Part I

Item 1.        Business

General Description of Registrant's Business and Its Development

        DNB Financial Corporation (the "Registrant" or "DNB"), a Pennsylvania business corporation, is a bank holding company registered with and supervised by the Board of Governors of the Federal Reserve System (Federal Reserve Board). The Registrant was incorporated on October 28, 1982 and commenced operations on July 1, 1983 upon consummation of the acquisition of all of the outstanding stock of Downingtown National Bank, now known as DNB First, National Association (the "Bank"). Since commencing operations, DNB's business has consisted primarily of managing and supervising the Bank, and its principal source of income has been derived from the Bank. At December 31, 2012, DNB had total consolidated assets, total liabilities and stockholders' equity of $639.6 million, $582.9 million, and $56.7 million, respectively.

        The Bank was organized in 1860. The Bank is a national banking association that is a member of the Federal Reserve System, the deposits of which are insured by the Federal Deposit Insurance Corporation ("FDIC"). The Bank is a full service commercial bank providing a wide range of services to individuals and small to medium sized businesses in the southeastern Pennsylvania market area, including accepting time, demand, and savings deposits and making secured and unsecured commercial, real estate and consumer loans. In addition, the Bank has twelve full service branches and one limited service branch and a full-service wealth management group known as "DNB First Wealth Management". The Bank's financial subsidiary, DNB Financial Services, Inc., (also know as "DNB Investments & Insurance") is a Pennsylvania licensed insurance agency, which, together with the Bank, sells a broad variety of insurance and investment products. The Bank's other subsidiaries are Downco, Inc. and DN Acquisition Company, Inc. which were incorporated in December 1995 and December 2008, respectively, for the purpose of acquiring and holding Other Real Estate Owned acquired through foreclosure or deed in-lieu-of foreclosure, as well as Bank-occupied real estate. In accordance with U.S. generally accepted accounting principles, the Registrant and the Bank operate as one segment, and therefore do not report segment financial information.

        The Bank's headquarters is located at 4 Brandywine Avenue, Downingtown, Pennsylvania. As of December 31, 2012, the Bank had total assets of $639.1 million, total deposits of $530.6 million and total stockholders' equity of $65.7 million. The Bank's business is not seasonal in nature. The FDIC, to the extent provided by law, insures its deposits. On December 31, 2012, the Bank had 112 full-time employees and 22 part-time employees.

        The Bank derives its income principally from interest charged on loans and, to a lesser extent, interest earned on investments, fees received in connection with the origination of loans, wealth management and other services. The Bank's principal expenses are interest expense on deposits and borrowings and operating expenses. Funds for activities are provided principally by operating revenues, deposit growth and the repayment of outstanding loans and investments.

        On April 2, 2012, the Bank entered into a Purchase and Assumption Agreement to acquire certain assets and assume certain liabilities of one full-service branch office located in Boothwyn, Pennsylvania (the "Branch Acquisition"). The Bank consummated the Branch Acquisition on June 11, 2012. The Bank purchased specified assets of the branch, including personal loans totaling $66,000, real estate, furniture and equipment totaling $670,000, and the Bank assumed approximately $15.9 million of deposits. The Branch Acquisition included the payment of $130,000 or a 0.82% premium on the deposits, which has been recorded as a core deposit intangible.

        The Bank encounters vigorous competition from a number of sources, including other commercial banks, thrift institutions, other financial institutions and financial intermediaries. In addition to commercial banks, Federal and state savings and loan associations, savings banks, credit unions and

2

industrial savings banks actively compete in the Bank's market area to provide a wide variety of banking services. Mortgage banking firms, real estate investment trusts, finance companies, insurance companies, leasing companies and brokerage companies, financial affiliates of industrial companies and certain government agencies provide additional competition for loans and for certain financial services. The Bank also competes for interest-bearing funds with a number of other financial intermediaries, which offer a diverse range of investment alternatives, including brokerage firms and mutual fund companies.

Supervision and Regulation — Registrant

Federal Banking Laws

        The Registrant is subject to a number of complex Federal banking laws, most notably the provisions of the Bank Holding Company Act of 1956, as amended ("Bank Holding Company Act") and the Change in Bank Control Act of 1978 ("Change in Control Act"), and to supervision by the Federal Reserve Board.

Bank Holding Company Act — Financial Holding Companies

        The Bank Holding Company Act requires a "company" (including the Registrant) to secure the prior approval of the Federal Reserve Board before it owns or controls, directly or indirectly, more than five percent (5%) of the voting shares or substantially all of the assets of any bank. It also prohibits acquisition by any "company" (including the Registrant) of more than five percent (5%) of the voting shares of, or interest in, or all or substantially all of the assets of, any bank located outside of the state in which a current bank subsidiary is located unless such acquisition is specifically authorized by laws of the state in which such bank is located. A "bank holding company" (including the Registrant) is prohibited from engaging in or acquiring direct or indirect control of more than five percent (5%) of the voting shares of any company engaged in non-banking activities unless the Federal Reserve Board, by order or regulation, has found such activities to be so closely related to banking or managing or controlling banks as to be a proper incident thereto. In making this determination, the Federal Reserve Board considers whether the performance of these activities by a bank holding company would offer benefits to the public that outweigh possible adverse effects. Applications under the Bank Holding Company Act and the Change in Control Act are subject to review, based upon the record of compliance of the applicant with the Community Reinvestment Act of 1977 ("CRA"). See further discussion below.

        The Registrant is required to file an annual report with the Federal Reserve Board and any additional information that the Federal Reserve Board may require pursuant to the Bank Holding Company Act. The Federal Reserve Board may also make examinations of the Registrant and any or all of its subsidiaries. Further, under Section 106 of the 1970 amendments to the Bank Holding Company Act and the Federal Reserve Board's regulations, a bank holding company and its subsidiaries are prohibited from engaging in certain tie-in arrangements in connection with any extension of credit or provision of credit or provision of any property or services. The so-called "anti-tie-in" provisions state generally that a bank may not extend credit, lease, sell property or furnish any service to a customer on the condition that the customer provide additional credit or service to the bank, to its bank holding company or to any other subsidiary of its bank holding company or on the condition that the customer not obtain other credit or service from a competitor of the bank, its bank holding company or any subsidiary of its bank holding company.

        Permitted Non-Banking Activities. The Federal Reserve Board permits bank holding companies to engage in non-banking activities so closely related to banking or managing or controlling banks as to be a proper incident thereto. A number of activities are authorized by Federal Reserve Board regulation, while other activities require prior Federal Reserve Board approval. The types of permissible activities are subject to change by the Federal Reserve Board. Revisions to the Bank Holding Company Act contained in the Federal Gramm-Leach Bliley Act of 1999 permit certain eligible bank holding companies to qualify as "financial holding companies" and thereupon engage in a wider variety of financial services such as

3

Table of Contents

securities and insurance activities, and subject such companies to increased competition from a wider variety of non-banking competitors as well as banks.

        Gramm-Leach Bliley Act of 1999 ("GLB"). This law repealed certain restrictions on bank and securities firm affiliations, and allows bank holding companies to elect to be treated as a "financial holding company" that can engage in approved "financial activities," including insurance, securities underwriting and merchant banking. Banks without holding companies can engage in many of these financial activities through a "financial subsidiary." The law also mandates functional regulation of bank securities activities. Banks' exemption from broker-dealer regulation is limited to, for example, trust, safekeeping, custodian, shareholder and employee benefit plans, sweep accounts, private placements (under certain conditions), self-directed IRAs, third party networking arrangements to offer brokerage services to bank customers, and the like. It also requires banks that advise mutual funds to register as investment advisers. The legislation provides for state regulation of insurance, subject to certain specified state preemption standards. It establishes which insurance products banks and bank subsidiaries may provide as principal or underwriter, and prohibits bank underwriting of title insurance, but also preempts state laws interfering with affiliations. GLB prohibits approval of new de novo thrift charter applications by commercial entities and limits sales of existing so-called "unitary" thrifts to commercial entities. The law bars banks, savings and loans, credit unions, securities firms and insurance companies, as well as other "financial institutions," from disclosing customer account numbers or access codes to unaffiliated third parties for telemarketing or other direct marketing purposes, and enables customers of financial institutions to "opt out" of having their personal financial information shared with unaffiliated third parties, subject to exceptions related to the processing of customer transactions and joint financial services marketing arrangements with third parties, as long as the institution discloses the activity to its customers and requires the third party to keep the information confidential. It requires policies on privacy and disclosure of information to be disclosed annually, requires federal regulators to adopt comprehensive regulations for ensuring the security and confidentiality of consumers' personal information, and allows state laws to give consumers greater privacy protections. The GLB has increased the competition the Bank faces from a wider variety of non-banking competitors as well as banks.

Change in Bank Control Act

        Under the Change in Control Act, no person, acting directly or indirectly or through or in concert with one or more other persons, may acquire "control" of any Federally insured depository institution unless the appropriate Federal banking agency has been given 60 days prior written notice of the proposed acquisition and within that period has not issued a notice disapproving of the proposed acquisition or has issued written notice of its intent not to disapprove the action. The period for the agency's disapproval may be extended by the agency. Upon receiving such notice, the Federal agency is required to provide a copy to the appropriate state regulatory agency, if the institution of which control is to be acquired is state chartered, and the Federal agency is obligated to give due consideration to the views and recommendations of the state agency. Upon receiving a notice, the Federal agency is also required to conduct an investigation of each person involved in the proposed acquisition. Notice of such proposal is to be published and public comment solicited thereon. A proposal may be disapproved by the Federal agency if the proposal would have anticompetitive effects, if the proposal would jeopardize the financial stability of the institution to be acquired or prejudice the interests of its depositors, if the competence, experience or integrity of any acquiring person or proposed management personnel indicates that it would not be in the interest of depositors or the public to permit such person to control the institution, if any acquiring person fails to furnish the Federal agency with all information required by the agency, or if the Federal agency determines that the proposed transaction would result in an adverse effect on a deposit insurance fund. In addition, the Change in Control Act requires that, whenever any Federally insured depository institution makes a loan or loans secured, or to be secured, by 25% or more of the outstanding voting stock of a Federally insured depository institution, the president or chief executive officer of the lending bank must

promptly report such fact to the appropriate Federal banking agency regulating the institution whose stock secures the loan or loans.

        Participation in U.S. Treasury Capital Purchase Program. On January 30, 2009, as part of the Capital Purchase Program administered by the United States Department of the Treasury, the Registrant entered into a Letter Agreement and a Securities Purchase Agreement with the U.S. Treasury, pursuant to which the Registrant issued and sold on January 30, 2009, and the U.S. Treasury purchased for cash on that date (i) 11,750 shares of the Registrant's Fixed Rate Cumulative Perpetual Preferred Stock, Series 2008A, par value $10.00 per share, having a liquidation preference of $1,000 per share (the "CPP Shares"), and (ii) a ten-year warrant to purchase up to 186,311 shares of the Registrant's common stock, $1.00 par value, at an exercise price of $9.46 per share, for an aggregate purchase price of $11,750,000 in cash. The issuance and sale of these securities was a private placement exempt from registration pursuant to Section 4(2) of the Securities Act of 1933. During its participation in this program, the Registrant was subject to a number of requirements and restrictions related to, among other things, executive compensation and governance standards.

        Participation in U.S. Treasury Small Business Lending Fund Program. On August 4, 2011, DNB entered into a Securities Purchase Agreement with the Secretary of the Treasury, pursuant to which DNB issued and sold to the Treasury 13,000 shares of its Non-Cumulative Perpetual Preferred Stock, Series 2011A ("Series 2011A Preferred Stock"), having a liquidation preference of $1,000 per share for aggregate proceeds of $13.0 million. The Securities Purchase Agreement was entered into, and the Series 2011A Preferred Stock was issued, pursuant to the Treasury's Small Business Lending Fund program ("SBLF"), a $30 billion fund established under the Small Business Jobs Act of 2010, that encourages lending to small businesses by providing capital to qualified community banks with assets of less than $10 billion. The securities sold in this transaction were exempt from registration under Section 4(2) of the Securities Act of 1933, as amended, as a transaction by DNB not involving a public offering. Of the $13.0 million in aggregate proceeds, $11,879,000 was used on August 4, 2011 to repurchase all CPP Shares ($11,750,000 was paid in principal and $128,900 in dividends related to the CPP Shares) held by the Treasury as described above.

        On September 21, 2011, DNB entered into a letter agreement (the "Warrant Letter Agreement") with the Treasury. Pursuant to the Warrant Letter Agreement, DNB Financial Corporation repurchased from the Treasury the warrant to purchase 186,311 shares of DNB Financial Corporation's common stock issued to the Treasury in January 2009 under CPP. DNB Financial Corporation paid a purchase price of $458,000 for the warrant.

        Participation in the Temporary Liquidity Guarantee Program. Due to the recent difficult economic conditions, deposit insurance per account owner has been raised to $250,000 for all types of accounts. That coverage was made permanent by the Dodd-Frank Act. In addition, the FDIC adopted an optional Temporary Liquidity Guarantee Program by which, for a fee, noninterest-bearing transaction accounts would receive unlimited insurance coverage until June 30, 2010, subsequently extended to December 31, 2010, and certain senior unsecured debt issued by institutions and their holding companies between October 13, 2008 and October 31, 2009 would be guaranteed by the FDIC through June 30, 2012, or in some cases, December 31, 2012. The Dodd-Frank Act provided for continued unlimited coverage for certain non-interest bearing accounts until December 31, 2012 (see discussion of Dodd-Frank Act below).

        Dodd-Frank Wall Street Reform and Consumer Protection Act. The federal government is considering a variety of reforms related to banking and the financial industry including, without limitation, the newly adopted Dodd-Frank Act. The Dodd-Frank Act is intended to promote financial stability in the U.S., reduce the risk of bailouts and protect against abusive financial services practices by improving accountability and transparency in the financial system and ending "too big to fail" institutions. It is the broadest overhaul of the U.S. financial system since the Great Depression, and much of its impact will be determined by the scope and substance of many regulations that will need to be adopted by various

5

Table of Contents

regulatory agencies to implement its provisions. For these reasons, the overall impact on DNB and its subsidiaries is unknown at this time.

        The Dodd-Frank Act delegates to various federal agencies the task of implementing its many provisions through regulation. Hundreds of new federal regulations, studies and reports addressing all of the major areas of the new law, including the regulation of banks and their holding companies, will be required, ensuring that federal rules and policies in this area will be further developing for months and years to come. Based on the provisions of the Dodd-Frank Act and anticipated implementing regulations, it is highly likely that banks and thrifts as well as their holding companies will be subject to significantly increased regulation and compliance obligations.

        The Dodd-Frank Act could require us to make material expenditures, in particular personnel training costs and additional compliance expenses, or otherwise adversely affect our business or financial results. It could also require us to change certain of our business practices, adversely affect our ability to pursue business opportunities we might otherwise consider engaging in, cause business disruptions and/or have other impacts that are as-of-yet unknown to DNB and the Bank. Failure to comply with these laws or regulations, even if inadvertent, could result in negative publicity, fines or additional licensing expenses, any of which could have an adverse effect on our cash flow and results of operations. For example, a provision of the Dodd-Frank Act is intended to preclude bank holding companies from treating future trust preferred securities issuances as Tier 1 capital for regulatory capital adequacy purposes. This provision may narrow the number of possible capital raising opportunities DNB and other bank holding companies might have in the future. As another example, the new law establishes the Consumer Financial Protection Bureau, which has been given substantive rule-making authority under most of the consumer protection regulations affecting the Bank and its customers. The Bureau and new rules it will issue may materially affect the methods and costs of compliance by the Bank in connection with future consumer related transactions.

Pennsylvania Banking Laws

        Under the Pennsylvania Banking Code of 1965, as amended ("PA Code"), the Registrant is permitted to control an unlimited number of banks, subject to prior approval of the Federal Reserve Board as more fully described above. The PA Code authorizes reciprocal interstate banking without any geographic limitation. Reciprocity between states exists when a foreign state's law authorizes Pennsylvania bank holding companies to acquire banks or bank holding companies located in that state on terms and conditions substantially no more restrictive than those applicable to such an acquisition by a bank holding company located in that state. Interstate ownership of banks in Pennsylvania with banks in Delaware, Maryland, New Jersey, Ohio, New York and other states is currently authorized. Some state laws still restrict de novo formations of branches in other states, but restrictions on interstate de novo banking have been relaxed by the Dodd-Frank Act. Pennsylvania law also provides Pennsylvania state chartered institutions elective parity with the power of national banks, federal thrifts, and state-chartered institutions in other states as authorized by the Federal Deposit Insurance Corporation ("Competing Institutions"). In some cases, this may give state chartered institutions broader powers than national banks such as the Bank, and may increase competition the Bank faces from other banking institutions.

Supervision and Regulation — Bank

        The operations of the Bank are subject to Federal and State statutes applicable to banks chartered under the banking laws of the United States, to members of the Federal Reserve System and to banks whose deposits are insured by the FDIC. Bank operations are also subject to regulations of the Office of the Comptroller of the Currency ("OCC"), the Federal Reserve Board and the FDIC.

6

---

Table of Contents

        The primary supervisory authority of the Bank is the OCC, who regularly examines the Bank. The OCC has the authority to prevent a national bank from engaging in an unsafe or unsound practice in conducting its business.

        Federal and state banking laws and regulations govern, among other things, the scope of a bank's business, the investments a bank may make, the reserves against deposits a bank must maintain, loans a bank makes and collateral it takes, the activities of a bank with respect to mergers and consolidations and the establishment of branches. All nationally and state-chartered banks in Pennsylvania are permitted to maintain branch offices in any county of the state. National bank branches may be established only after approval by the OCC. It is the general policy of the OCC to approve applications to establish and operate domestic branches, including ATMs and other automated devices that take deposits, provided that approval would not violate applicable Federal or state laws regarding the establishment of such branches. The OCC reserves the right to deny an application or grant approval subject to conditions if (1) there are significant supervisory concerns with respect to the applicant or affiliated organizations, (2) in accordance with CRA, the applicant's record of helping meet the credit needs of its entire community, including low and moderate income neighborhoods, consistent with safe and sound operation, is less than satisfactory, or (3) any financial or other business arrangement, direct or indirect, involving the proposed branch or device and bank "insiders" (directors, officers, employees and 10% or greater shareholders) involves terms and conditions more favorable to the insiders than would be available in a comparable transaction with unrelated parties.

        The Bank, as a subsidiary of a bank holding company, is subject to certain restrictions imposed by the Federal Reserve Act on any extensions of credit to the bank holding company or its subsidiaries, on investments in the stock or other securities of the bank holding company or its subsidiaries and on taking such stock or securities as collateral for loans. The Federal Reserve Act and Federal Reserve Board regulations also place certain limitations and reporting requirements on extensions of credit by a bank to principal shareholders of its parent holding company, among others, and to related interests of such principal shareholders. In addition, such legislation and regulations may affect the terms upon which any person becoming a principal shareholder of a holding company may obtain credit from banks with which the subsidiary bank maintains a correspondent relationship.

Capital Adequacy

        Federal banking laws impose on banks certain minimum requirements for capital adequacy. Federal banking agencies have issued certain "risk-based capital" guidelines, and certain "leverage" requirements on member banks such as the Bank. Banking regulators have authority to require higher minimum capital ratios for an individual bank or bank holding company in view of its circumstances.

        Minimum Capital Ratios. The risk-based guidelines require all banks to maintain two "risk-weighted assets" ratios. The first is a minimum ratio of total capital ("Tier 1" and "Tier 2" capital) to risk-weighted assets equal to 8.00%; the second is a minimum ratio of "Tier 1" capital to risk-weighted assets equal to 4.00%. Assets are assigned to five risk categories, with higher levels of capital being required for the categories perceived as representing greater risk. In making the calculation, certain intangible assets must be deducted from the capital base. The risk-based capital rules are designed to make regulatory capital requirements more sensitive to differences in risk profiles among banks and bank holding companies and to minimize disincentives for holding liquid assets.

        The risk-based capital rules also account for interest rate risk. Institutions with interest rate risk exposure above a normal level would be required to hold extra capital in proportion to that risk. A bank's exposure to declines in the economic value of its capital due to changes in interest rates is a factor that the banking agencies will consider in evaluating a bank's capital adequacy. The rule does not codify an explicit minimum capital charge for interest rate risk. The Bank currently monitors and manages its assets and liabilities for interest rate risk, and management believes that the interest rate risk rules which have been implemented and proposed will not materially adversely affect our operations.

Table of Contents

        The "leverage" ratio rules require banks which are rated the highest in the composite areas of capital, asset quality, management, earnings, liquidity and sensitivity to market risk to maintain a ratio of "Tier 1" capital to "adjusted total assets" (equal to the bank's average total assets as stated in its most recent quarterly Call Report filed with its primary federal banking regulator, minus end-of-quarter intangible assets that are deducted from Tier 1 capital) of not less than 3.00%. For banks which are not the most highly rated, the minimum "leverage" ratio will range from 4.00% to 5.00%, or higher at the discretion of the bank's primary federal regulator, and is required to be at a level commensurate with the nature of the level of risk of the bank's condition and activities.

        For purposes of the capital requirements, "Tier 1" or "core" capital is defined to include common stockholders' equity and certain non-cumulative perpetual preferred stock and related surplus. "Tier 2" or "qualifying supplementary" capital is defined to include a bank's allowance for loan and lease losses up to 1.25% of risk-weighted assets, plus certain types of preferred stock and related surplus, certain "hybrid capital instruments" and certain term subordinated debt instruments.

        New Proposed Capital Rules. On June 7, 2012, the Federal Reserve proposed rules that would substantially amend the regulatory risk-based capital rules applicable to the Corporation and the Bank. The FDIC and the OCC subsequently proposed the rules on June 12, 2012. The proposed rules implement the "Basel III" regulatory capital reforms and changes required by the Dodd-Frank Act. "Basel III" refers to two consultative documents released by the Basel Committee on Banking Supervision in December 2009, the rules text released in December 2010, and loss absorbency rules issued in January 2011, which include significant changes to bank capital, leverage and liquidity requirements. The proposed rules were subject to a comment period that expired on October 22, 2012.

        The proposed rules include new risk-based capital and leverage ratios, which were to be phased in from 2013 to 2019 but which have been delayed pending further review of the proposed implementing regulations, and would refine the definition of what constitutes "capital" for purposes of calculating those ratios. The proposed new minimum capital level requirements applicable to the Corporation and the Bank under the proposals would be: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6% (increased from 4%); (iii) a total capital ratio of 8% (unchanged from current rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The proposed rules would also establish a "capital conservation buffer" of 2.5% above the new regulatory minimum capital requirements, which must consist entirely of common equity Tier 1 capital and would result in the following minimum ratios: (i) a common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%, and (iii) a total capital ratio of 10.5%. The new capital conservation buffer requirement would be phased in beginning in January 2016 at 0.625% of risk-weighted assets and would increase by that amount each year until fully implemented in January 2019. An institution would be subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level falls below the buffer amount. These limitations would establish a maximum percentage of eligible retained income that could be utilized for such actions.

        Basel III provided discretion for regulators to impose an additional buffer, the "countercyclical buffer," of up to 2.5% of common equity Tier 1 capital to take into account the macro-financial environment and periods of excessive credit growth. However, the proposed rules permit the countercyclical buffer to be applied only to "advanced approach banks" (i.e. , banks with $250 billion or more in total assets or $10 billion or more in total foreign exposures), which currently excludes the Corporation and the Bank. The proposed rules also implement revisions and clarifications consistent with Basel III regarding the various components of Tier 1 capital, including common equity, unrealized gains and losses, as well as certain instruments that will no longer qualify as Tier 1 capital, some of which would be phased out over time.

        The federal bank regulatory agencies also proposed revisions to the prompt corrective action framework, which is designed to place restrictions on insured depository institutions, including the Bank, if their capital levels begin to show signs of weakness. These revisions would take effect January 1, 2015.

Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions would be required to meet the following increased capital level requirements in order to qualify as "well capitalized:" (i) a new common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8% (increased from 6%); (iii) a total capital ratio of 10% (unchanged from current rules); and (iv) a Tier 1 leverage ratio of 5% (increased from 4%).

        The proposed rules set forth certain changes for the calculation of risk-weighted assets, which we would be required to utilize beginning January 1, 2015. The standardized approach proposed rule utilizes an increased number of credit risk exposure categories and risk weights, and also addresses: (i) a proposed alternative standard of creditworthiness consistent with Section 939A of the Dodd-Frank Act; (ii) revisions to recognition of credit risk mitigation; (iii) rules for risk weighting of equity exposures and past due loans; (iv) revised capital treatment for derivatives and repo-style transactions; and (v) disclosure requirements for top-tier banking organizations with $50 billion or more in total assets that are not subject to the "advance approach rules" that apply to banks with greater than $250 billion in consolidated assets.

        On November 9, 2012, the U.S. federal banking agencies released a joint press release indefinitely delaying the January 1, 2013 implementation date for their proposed rules that would revise and replace the current regulatory capital rules according to Basel III and certain provisions of Dodd-Frank.

        Prompt Corrective Action. Federal banking law mandates certain "prompt corrective actions," which Federal banking agencies are required to take, and certain actions which they have discretion to take, based upon the capital category into which a Federally regulated depository institution falls. Regulations have been adopted by the Federal bank regulatory agencies setting forth detailed procedures and criteria for implementing prompt corrective action in the case of any institution that is not adequately capitalized. Under the rules, an institution will be deemed to be "adequately capitalized" or better if it exceeds the minimum Federal regulatory capital requirements. However, it will be deemed "undercapitalized" if it fails to meet the minimum capital requirements, "significantly undercapitalized" if it has a total risk-based capital ratio that is less than 6.0%, a Tier 1 risk-based capital ratio that is less than 3.0%, or a leverage ratio that is less than 3.0%, and "critically undercapitalized" if the institution has a ratio of tangible equity to total assets that is equal to or less than 2.0%. The rules require an undercapitalized institution to file a written capital restoration plan, along with a performance guaranty by its holding company or a third party. In addition, an undercapitalized institution becomes subject to certain automatic restrictions including a prohibition on the payment of dividends, a limitation on asset growth and expansion, and in certain cases, a limitation on the payment of bonuses or raises to senior executive officers, and a prohibition on the payment of certain "management fees" to any "controlling person". Institutions that are classified as undercapitalized are also subject to certain additional supervisory actions, including increased reporting burdens and regulatory monitoring, a limitation on the institution's ability to make acquisitions, open new branch offices, or engage in new lines of business, obligations to raise additional capital, restrictions on transactions with affiliates, and restrictions on interest rates paid by the institution on deposits. In certain cases, bank regulatory agencies may require replacement of senior executive officers or directors, or sale of the institution to a willing purchaser. If an institution is deemed to be "critically undercapitalized" and continues in that category for four quarters, the statute requires, with certain narrowly limited exceptions, that the institution be placed in receivership.

        DNB's management believes that the Bank is "well capitalized" for regulatory capital purposes. Please see the table detailing the Bank's compliance with minimum capital ratios, in Note 16 ("Regulatory Matters") to DNB's audited financial statements in this Form 10-K.

        Under the Federal Deposit Insurance Act, the OCC possesses the power to prohibit institutions regulated by it, such as the Bank, from engaging in any activity that would be an unsafe and unsound banking practice and in violation of the law. Moreover, Federal law enactments have expanded the circumstances under which officers or directors of a bank may be removed by the institution's Federal supervisory agency; unvested and further regulated lending by a bank to its executive officers, directors,

principal shareholders or related interests thereof; and unvested management personnel of a bank from serving as directors or in other management positions with certain depository institutions whose assets exceed a specified amount or which have an office within a specified geographic area; and unvested management personnel from borrowing from another institution that has a correspondent relationship with their bank.

        Interstate Banking. Federal law permits interstate bank mergers and acquisitions. Limited branch purchases are still subject to state laws. Pennsylvania law permits out-of-state banking institutions to establish branches in Pennsylvania with the approval of the Pennsylvania Banking Department, provided the law of the state where the banking institution is located would permit a Pennsylvania banking institution to establish and maintain a branch in that state on substantially similar terms and conditions. It also permits Pennsylvania banking institutions to maintain branches in other states. The Dodd-Frank Act created a more permissive interstate branching regime by permitting banks to establish branches de novo in any state if a bank chartered by such state would have been permitted to establish the branch. Bank management anticipates that interstate banking will continue to increase competitive pressures in the Bank's market by permitting entry of additional competitors, but management is of the opinion that this will not have a material impact upon the anticipated results of operations of the Bank.

        Bank Secrecy Act and OFAC. Under the Bank Secrecy Act ("BSA"), the Bank is required to report to the Internal Revenue Service, currency transactions of more than $10,000 or multiple transactions of which the Bank is aware in any one day that aggregate in excess of $10,000. Civil and criminal penalties are provided under the BSA for failure to file a required report, for failure to supply information required by the BSA or for filing a false or fraudulent report. The Department of the Treasury's Office of Foreign Asset Control ("OFAC") administers and enforces economic and trade sanctions against targeted foreign countries, terrorism-sponsoring jurisdictions and organizations, and international narcotics traffickers based on U.S. foreign policy and national security goals. OFAC acts under presidential wartime and national emergency powers and authority granted by specific legislation to impose controls on transactions and freeze foreign assets under U.S. jurisdiction. Acting under authority delegated from the Secretary of the Treasury, OFAC promulgates, develops, and administers the sanctions under its statutes and executive orders. OFAC requirements are separate and distinct from the BSA, but both OFAC requirements and the BSA share a common national security goal. Because institutions and regulators view compliance with OFAC sanctions as related to BSA compliance obligations, supervisory examination for OFAC compliance is typically connected to examination of an institution's BSA compliance. Examiners focus on a banking organization's compliance processes and evaluate the sufficiency of a banking organization's implementation of policies, procedures and systems to ensure compliance with OFAC regulations.

        USA PATRIOT Act. The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (together with its implementing regulations, the "Patriot Act"), designed to deny terrorists and others the ability to obtain access to the United States financial system, has significant implications for banks and other financial institutions. It required DNB and its subsidiary to implement new policies and procedures or amend existing policies and procedures with respect to, anti-money laundering, compliance, suspicious activity and currency transaction reporting and due diligence on customers, as well as related matters. The Patriot Act permits and in some cases requires information sharing for counter-terrorist purposes between federal law enforcement agencies and financial institutions, as well as among financial institutions, and it requires federal banking agencies to evaluate the effectiveness of an institution in combating money laundering activities, both in ongoing examinations and in connection with applications for regulatory approval.

        Deposit Insurance Assessments. The deposits of the Bank are insured by the FDIC up to the limits set forth under applicable law and are subject to deposit insurance premium assessments. The FDIC imposes a risk based deposit premium assessment system, under which the amount of FDIC assessments paid by an individual insured depository institution, such as the Bank, is based on the level of risk incurred in its

10

Table of Contents

activities. The FDIC places a depository institution in one of four risk categories determined by reference to its capital levels and supervisory ratings. In addition, in the case of those institutions in the lowest risk category, the FDIC further determines its assessment rates based on certain specified financial ratios. Pursuant to the Federal Deposit Insurance Act, the FDIC has authority and the responsibility to establish deposit insurance assessments at rates sufficient to maintain the designated reserve ratio of the Deposit Insurance Fund at a level between 1.15% and 1.5% of estimated insured deposits, and to take action to restore the designated reserve ratio to at least 1.15% of estimated insured deposits when it falls below that level. As of June 30, 2008, the designated reserve ratio fell below 1.15%, to 1.01%. On October 7, 2008, the FDIC established a restoration plan which it has updated periodically since then to respond to deteriorating economic conditions. Conditions in the banking industry continued to deteriorate through 2008 and 2009. According to the FDIC's Quarterly Banking Profile for the Fourth Quarter 2009, as of December 30, 2009 the designated reserve ratio had fallen to (0.39%), down from (0.16%) on September 30, 2009, and 0.36% as of December 31, 2008. The FDIC reports that the December 31, 2009 reserve ratio is the lowest on record for a combined bank and thrift insurance fund. In response to the declining reserve ratio, the FDIC took a series of extraordinary deposit insurance assessment actions during 2009.

        Effective as of April 1, 2011, the FDIC adopted changes to its base and risk-based deposit insurance rates. Pursuant to the new rules, a bank's annual assessment base rates were as follows, depending on the bank's risk category:

Initial and Total Base Assessment Rates*

        On November 12, 2009, the FDIC adopted a final rule to require insured institutions to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009, and for all of 2010, 2011, and 2012. The prepaid assessment was collected on December 30, 2009, along with the institution's regular quarterly risk-based deposit insurance assessment for the third quarter of 2009. For purposes of calculating the prepaid assessment, each institution's assessment rate was its total base assessment rate in effect on September 30, 2009. In calculating the prepayment attributable to 2011 and thereafter, it is calculated using the September 29, 2009 increase in 2011 base assessment rates. In addition, future deposit growth was reflected in the prepayment by assuming that an institution's third quarter 2009 assessment base would be increased quarterly at a 5 percent annual growth rate through the end of 2012. The FDIC began to draw down institutions' prepaid assessments on March 30, 2010, representing payment for the regular quarterly risk-based assessment for the fourth quarter of 2009. In announcing these initiatives, the FDIC stated that, while the prepaid assessment would not immediately affect bank earnings, each institution would record the entire amount of its prepaid assessment as a prepaid expense asset as of December 30, 2009, the date

11

Table of Contents

the payment was made and, as of December 31, 2009 and each quarter thereafter, record an expense or charge to earnings for its regular quarterly assessment and an offsetting credit to the prepaid assessment until the asset is exhausted. Once the asset is exhausted, institutions would resume paying and accounting for quarterly deposit insurance assessments as they currently do. The total amount of the Bank's deposit insurance assessment prepayment was $3.1 million.

        The Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, that was enacted by Congress on July 15, 2010, and was signed into law by President Obama on July 21, 2010, enacted a number of changes to the federal deposit insurance regime that will affect the deposit insurance assessments the Bank will be obligated to pay in the future. For example:

•

The law permanently raises the federal deposit insurance limit to $250,000 per account ownership. This change may have the effect of increasing losses to the FDIC insurance fund on future failures of other insured depository institutions.



•

The new law makes deposit insurance coverage unlimited in amount for non-interest bearing transaction accounts until December 31, 2012. This change may also have the effect of increasing losses to the FDIC insurance fund on future failures of other insured depository institutions. Effective January 1, 2013, non-interest bearing transaction accounts will fall under the existing FDIC insurance limit of $250,000 per account ownership.



•

The law increases the insurance fund's minimum designated reserve ratio from 1.15 to 1.35, and removes the current 1.50 cap on the reserve ratio. The law gives the FDIC discretion to suspend or limit the declaration or payment of dividends even when the reserve ratio exceeds the minimum designated reserve ratio.

        The Dodd-Frank Act expands the base for FDIC insurance assessments, requiring that assessments be based on the average consolidated total assets less tangible equity capital of a financial institution. On February 7, 2011, the FDIC approved a final rule to implement the foregoing provision of the Dodd-Frank Act and to make other changes to the deposit insurance assessment system applicable to insured depository institutions with over $10 billion in assets. Among other things, the final rule eliminates risk categories and the use of long-term debt issuer ratings in calculating risk-based assessments, and instead implements a scorecard method, combining CAMELS ratings and certain forward-looking financial measures to assess the risk an institution poses to the Deposit Insurance Fund. The final rule also revises the assessment rate schedule for large institutions and highly complex institutions to provide assessments ranging from 2.5 to 45 basis points.

        Each of these changes may increase the rate of FDIC insurance assessments to maintain or replenish the FDIC's deposit insurance fund. This could, in turn, raise the Bank's future deposit insurance assessment costs. On the other hand, the law changes the deposit insurance assessment base so that it will generally be equal to consolidated assets less tangible equity. This change of the assessment base from an emphasis on deposits to an emphasis on assets is generally considered likely to cause larger banking organizations to pay a disproportionately higher portion of future deposit insurance assessments, which may, correspondingly, lower the level of deposit insurance assessments that smaller community banks such as the Bank may otherwise have to pay in the future. On December 14, 2010, the FDIC issued a final rule setting the insurance fund's designated reserve ratio at 2, which is in excess of the 1.35 minimum designated reserve ratio established by the Dodd-Frank Act. While it is likely that the new law will increase the Bank's future deposit insurance assessment costs, the specific amount by which the new law's combined changes will affect the Bank's deposit insurance assessment costs is hard to predict, particularly because the new law gives the FDIC enhanced discretion to set assessment rate levels.

        In addition to deposit insurance assessments, banks are subject to assessments to pay the interest on Financing Corporation bonds. The Financing Corporation was created by Congress to issue bonds to finance the resolution of failed thrift institutions. The FDIC sets the Financing Corporation assessment

12

Table of Contents

rate every quarter. The current annual Financing Corporation assessment rate is 64 basis points on the deposit insurance assessment base, as defined above, which we anticipate will result in an aggregate estimated FICO assessment payment by the Bank of $36,000 in 2013.

        Other Laws and Regulations. The Bank is subject to a variety of consumer protection laws, including the Truth in Lending Act, the Truth in Savings Act adopted as part of the Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), the Equal Credit Opportunity Act, the Home Mortgage Disclosure Act, the Electronic Funds Transfer Act, the Real Estate Settlement Procedures Act and the regulations adopted hereunder. In the aggregate, compliance with these consumer protection laws and regulations involves substantial expense and administrative time on the part of the Bank and DNB.

        Legislation and Regulatory Changes. From time to time, legislation is enacted which has the effect of increasing the cost of doing business, limiting or expanding permissible activities and/or affecting the competitive balance between banks and other financial institutions. Proposals to change the laws and regulations governing the operations and taxation of banks, bank holding companies and other financial institutions are frequently made in Congress, and before various bank regulatory agencies. No prediction can be made as to the likelihood of any major changes or the impact such changes might have on DNB and its subsidiary Bank.

        Effect of Government Monetary Policies. The earnings of DNB are and will be affected by domestic economic conditions and the monetary and fiscal policies of the United States Government and its agencies (particularly the Federal Reserve Board). The monetary policies of the Federal Reserve Board have had and will likely continue to have, an important impact on the operating results of commercial banks through its power to implement national monetary policy in order, among other things, to curb inflation or combat a recession. The Federal Reserve Board has a major effect upon the levels of bank loans, investments and deposits through its open market operations in United States Government securities and through its regulation of, among other things, the discount rate on borrowing of member banks and the reserve requirements against member bank deposits. It is not possible to predict the nature and impact of future changes in monetary and fiscal policies.

        All of DNB's revenues are attributable to customers located in the United States, and primarily from customers located in Southeastern Pennsylvania. All of Registrant's assets are located in the United States and in Southeastern Pennsylvania. Registrant has no activities in foreign countries and hence no risks attendant to foreign operations.

        DNB files reports with the Securities and Exchange Commission ("SEC"). The public may read and copy any materials we file with the SEC at the SEC's Public Reference Room at 450 fifth Street, NW, Washington, DC 20549. The public may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330.

Item 7.        Management's Discussion and Analysis of Financial Condition and Results of Operations

I.     Introductory Overview

        DNB Financial Corporation ("DNB") is a bank holding company whose bank subsidiary, DNB First, National Association (the "Bank") is a nationally chartered commercial bank with trust powers, and a member of the FDIC. DNB provides a broad range of banking services to individual and corporate customers through its thirteen community offices located throughout Chester and Delaware Counties, Pennsylvania. DNB is a community banking organization that focuses its lending and other services on businesses and consumers in the local market area. DNB funds all these activities with retail and business deposits and borrowings. Through its Wealth Management division, the Bank provides wealth management and trust services to individuals, businesses and non-profit organizations. The Bank and its subsidiary, DNB Investments and Insurance, make available certain non-depository products and services, such as securities brokerage, mutual funds, life insurance and annuities.

        DNB earns revenues and generates cash flows by lending funds to commercial and consumer customers in its marketplace. DNB generates its largest source of interest income through its lending function. A secondary source of interest income is DNB's investment portfolio, which provides liquidity and cash flows for future lending needs.

        In addition to interest earned on loans and investments, DNB earns revenues from fees it charges customers for non-lending services. These services include wealth management and trust services; brokerage and investment services; cash management services; banking and ATM services; as well as safekeeping and other depository services.

        To ensure we remain well positioned to meet the growing needs of our customers and communities and to meet the challenges of the 21st century, we've worked to build awareness of our full-service capabilities and ability to meet the needs of a wide range of customers. This served to not only retain our existing, customer base, but to position ourselves as an attractive financial institution on which younger individuals and families can build their dreams. To that end, DNB continues to make appropriate investments in all areas of our business, including people, technology, facilities and marketing.

        Highlights of DNB's results for the year-end December 31, 2012 include:

•

Increased earnings — Net income increased $337,000 or 6.9% year over year. Net income was $5.2 million or $1.79 per diluted share in 2012, compared to $4.9 million or $1.53 per diluted share in 2011.



•

Improvement of net interest margin — DNB's net interest margin, on a tax-equivalent basis, improved 6 basis points from 3.72% in 2011 to 3.78% in 2012. The most significant factor in this improvement was the reduction in the cost of interest bearing liabilities, which declined from 0.93% in 2011 to 0.78% in 2012.



•

DNB continued to focus on growing fee-based income — Our Wealth Management area experienced a 31.6% increase over 2011, exceeding $1.0 million for the first time compared to $785,000 in 2011. Fees for deposit and cash management services also increased $216,000 or 18.9% over 2011.



•

Strengthened capital position — Shareholder's equity increased $5.7 million to $56.7 million at December 31, 2012 compared to December 31, 2011, reflecting our solid earnings growth. DNB's Tier 1 leverage ratio and Tier 1 risk-based capital ratio were 10.50% and 14.60%, exceeding regulatory definitions for a well capitalized institution.

        The global and U.S. economies have experienced significantly reduced business activity as a result of disruptions in the financial system during the past four years. Dramatic declines in the housing market, with falling home prices and increasing foreclosures and unemployment, have resulted in significant write-

Table of Contents

downs of asset values by financial institutions, including government-sponsored entities and major commercial and investment banks. As a result of the recession, retail customers may delay borrowing from DNB as unemployment remains high and availability to borrow against equity in primary residences diminishes. As the U.S. economy moves through a period of recession, delinquencies will rise as the value of homes decline and DNB's borrowers experience financial difficulty due to corporate downsizing, reduced sales, or other negative events which may impact their ability to meet their contractual loan payments. As a result of these negative trends in the economy and their impact on our borrowers' ability to repay their loans, DNB made a $1.5 million provision in 2012 in response to DNB's increased level of non-performing loans which increased $2.8 million during the year to $10.4 million at December 31, 2012.

        In addition, DNB's net interest margin has been impacted by these changes in the economy. Management has been aggressive in managing DNB's cost of funds during the year by implementing carefully planned pricing strategies, designed to offset the decline in rates on earning assets, while matching liquidity needs. Our composite cost of funds for 2012 dropped 15 basis points to 0.78%, from 0.93% in 2011. DNB's net interest margin increased to 3.78% in 2012 from 3.72% in 2011.

        Earnings. For the year ended December 31, 2012, DNB reported net income of $5.2 million, an increase of $337,000 from the $4.9 million reported for the year ended December 31, 2011, or $1.79 per share versus $1.53 per share, respectively, on a fully diluted basis. DNB's earnings were favorably impacted by a higher net interest margin and a higher level of non-interest income. Although DNB reported an increase in earnings in 2012 over 2011, our operations and earnings are subject to the same negative economic conditions challenging all commercial banking institutions.

        Asset Quality. Non-performing assets were $11.7 million at December 31, 2012 compared to $11.6 million at December 31, 2011. Non-performing assets as of December 31, 2012 were comprised of $9.6 million of non-accrual loans and leases, $869,000 of loans and leases delinquent over ninety days and still accruing, as well as $1.1 million of Other Real Estate Owned ("OREO") and $126,000 in other repossessed property. As of December 31, 2012, the non-performing loans to total loans ratio increased to 2.63% compared to 1.89% at December 31, 2011. The non-performing assets to total assets ratio decreased to 1.82% at December 31, 2012, compared to 1.91% at December 31, 2011. The allowance for credit losses was $6.8 million at December 31, 2012, compared to $6.2 million at December 31, 2011. The allowance to total loans was 1.72% at December 31, 2012 compared to 1.53% at December 31, 2011. DNB's delinquency ratio (the total of all delinquent loans and leases plus loans greater than 90 days and still accruing, divided by total loans and leases) was 2.36% at December 31, 2012, up from 2.19% at December 31, 2011. The increase in delinquencies during 2012 occurred primarily in the commercial loan portfolio.

II.    Overview of Financial Condition — Major Changes and Trends

        At December 31, 2012, DNB had consolidated assets of $639.6 million and a Tier I/Leverage Capital Ratio of 10.50%. Loans and leases comprise 64.5% of earning assets, while investments and overnight funds constitute the remainder. During 2012, assets increased $32.5 million to $639.6 million at December 31, 2012, compared to $607.1 million at December 31, 2011. During the same period, investment securities increased $57.4 million to $201.3 million, while the loan and lease portfolio decreased $7.2 million, or 1.78%, to $396.5 million. Deposits increased $32.9 million to $530.4 million at December 31, 2012. DNB's liabilities are comprised of a high level of core deposits with a low cost of funds in addition to a moderate level of borrowings with costs that are more volatile than core deposits.

        Comprehensive 5-Year Plan. During the second quarter of 2012, management updated the 5-year strategic plan that was designed to reposition its balance sheet and improve core earnings. Through the plan, management will endeavor to expand its loan portfolio through new originations, increased loan participations, as well as strategic loan and lease receivable purchases. Management also plans to reduce

the absolute level of borrowings with cash flows from existing loans and investments as well as from new deposit growth. A discussion on DNB's Key Strategies follows below:

•

Focus on penetrating existing markets to maximize profitability



•

Grow loans and diversify the mix



•

Improve asset quality



•

Focus on profitable customer segments



•

Grow and diversify non-interest income, primarily wealth management



•

Focus on reducing DNB's cost of funds by changing DNB's mix of deposits



•

Focus on cost containment and improving operational efficiencies

        Strategic Plan Update. During the year ended December 31, 2012, management focused on reducing our composite cost of funds as well as strengthening DNB's net interest margin. The composite cost of funds for the year ended December 31, 2012 was 0.78% compared to 0.93% in 2011. The net interest margin for the year ended December 31, 2012 was 3.78% compared to 3.72% in 2011. Management continued to actively manage deposits during 2012 to reduce DNB's cost of funds. Time deposits decreased $2.9 million to $102.3 million at December 31, 2012 compared to $105.2 million at December 31, 2011. Transaction and savings accounts increased $35.8 million during the year ended December 31, 2012. Overall, non-interest income increased $862,000 or 23.51% to $4.5 million. Positive trends were observed for the year ended December 31, 2012, in two key business lines that make up total non-interest income: service charges on deposits increased 18.9% or $216,000, and wealth management fees increased 31.59% or $248,000 when compared to the same period in 2011. These increases were partially offset by a $123,000 decrease on gains on sale of Small Business Administration ("SBA") loans. Non-interest expense for the year ended December 31, 2012 showed an increase of 5.70% or $954,000, compared to the same period in 2011. During 2012, DNB had $440,000 of write-downs on OREO and other repossessed property that it held compared to $23,000 of such write-downs during 2011. Absent these write-downs, non-interest expenses increased $537,000 or 3.21% year over year. Approximately $65,000 of the $954,000 increase is attributable to the purchase of assets and the assumption of deposits associated with the Boothwyn branch acquisition which was completed during the second quarter of 2012.

        Management's strategies are designed to direct DNB's tactical investment decisions and support financial objectives. DNB's most significant revenue source continues to be net interest income, defined as total interest income less total interest expense, which in 2012 accounted for approximately 82.9% of total revenue. To produce net interest income and consistent earnings growth over the long-term, DNB must generate loan and deposit growth at acceptable economic spreads within its market area. To generate and grow loans and deposits, DNB must focus on a number of areas including, but not limited to, the economy, branch expansion, sales practices, customer satisfaction and retention, competition, customer behavior, technology, product innovation and credit performance of its customers.

        Management has made a concerted effort to improve the measurement and tracking of business lines and overall corporate performance levels. Improved information systems have increased DNB's ability to track key indicators and enhance corporate performance levels. Better measurement against goals and objectives and increased accountability will be integral in attaining desired loan, deposit and fee income production.

III.  DNB's Principal Products and Services

        Loans and Lending Services. DNB's primary source of earnings and cash flows is derived from its lending function. The commercial loan and lease portfolios amounted to $328.4 million or 82.8% of total loans as of December 31, 2012. DNB focuses on providing these products to small to mid-size businesses throughout Chester and Delaware Counties. In keeping with DNB's goal to match customer business initiatives with products designed to meet their needs, DNB offers a wide variety of fixed and variable rate loans that are priced competitively. DNB serves this market by providing funds for the purchase of business property or ventures, working capital lines, Small Business Administration loans, lease financing for equipment and for a variety of other purposes.

        As a community bank, DNB also serves consumers by providing home equity and home mortgages, as well as term loans for the purchase of consumer goods. Residential mortgage and consumer loans remained relatively flat in 2012 compared to 2011, primarily due to the current economic environment, which has lessened consumer demand for home equity loan products as a result of falling housing prices and a higher unemployment rate. In addition to providing funds to customers, DNB also provides a variety of services to its commercial customers. These services, such as cash management, remote capture, commercial sweep accounts, internet banking, letters of credit and other lending services are designed to meet our customer needs and help them become successful. DNB provides these services to assist its customers in obtaining financing, securing business opportunities, providing access to new resources and managing cash flows.

        Deposit Products and Services. DNB's primary source of funds is derived from customer deposits, which are typically generated by DNB's thirteen branch offices. DNB's deposit base, while highly concentrated in central Chester County, extends to southern Chester County and into parts of Delaware and Lancaster Counties. In addition, a growing amount of new deposits are being generated through expanded government service offerings and as a part of comprehensive loan or wealth management relationships.

        The majority of DNB's deposit mix consists of low costing core deposits, (demand, NOW and savings accounts). The remaining deposits are comprised of rate-sensitive money market and time products. DNB offers tiered savings and money market accounts, designed to attract high dollar, less volatile funds. Certificates of deposit and IRAs are traditionally offered with interest rates commensurate with their terms.

        Non-Deposit Products and Services. DNB offers non-deposit products and services through its subsidiaries under the names "DNB Investments & Insurance" and "DNB First Investment Management & Trust." Revenues under these entities were $1.0 million and $785,000 for 2012 and 2011, respectively.

DNB Investments & Insurance.  Through a partnership with Cetera Investment Services, LLC, DNB Investments & Insurance offers a complete line of investment and insurance products.

IV.    Material Challenges, Risks and Opportunities

A.    Interest Rate Risk Management.

        Interest rate risk is the exposure to adverse changes in net interest income due to changes in interest rates. DNB considers interest rate risk a predominant risk in terms of its potential impact on earnings. Interest rate risk can occur for any one or more of the following reasons: (a) assets and liabilities may mature or re-price at different times; (b) short-term or long-term market rates may change by different amounts; or (c) the remaining maturity of various assets or liabilities may shorten or lengthen as interest rates change.

        The principal objective of DNB's interest rate risk management is to evaluate the interest rate risk included in certain on and off balance sheet accounts, determine the level of risk appropriate given DNB's business strategy, operating environment, capital and liquidity requirements and performance objectives, and manage the risk consistent with approved guidelines. Through such management, DNB seeks to reduce the vulnerability of its operations to changes in interest rates. DNB's Asset Liability Committee (the "ALCO") is responsible for reviewing DNB's asset/liability policies and interest rate risk position and making decisions involving asset liability considerations. The ALCO meets on a monthly basis and reports trends and DNB's interest rate risk position to the Board of Directors on a quarterly basis. The extent of the movement of interest rates is an uncertainty that could have a negative impact on DNB's earnings. (See additional discussion in Item 7a. Quantitative and Qualitative Disclosures About Market Risk on page 45 of this Form 10-K.)

1.    Net Interest Margin

        DNB's net interest margin is the ratio of net interest income to average interest-earning assets. Unlike the interest rate spread, which measures the difference between the rates on earning assets and interest paying liabilities, the net interest margin measures that spread plus the effect of net free funding sources. This is a more meaningful measure of profitability because a bank can have a narrow spread but a high level of equity and non-interest-bearing deposits, resulting in a good net interest margin. One of the most critical challenges DNB faced over the last several years was the impact of historically low interest rates and a narrower spread between short-term rates and long-term rates as noted in the tables below.

 

22

---

Table of Contents

        In general, financial institutions price their fixed rate loans off of 5 and 10 year treasuries and price their deposits off of shorter indices, like the Federal Funds Sold rate. As you can see in the table above, the spread between the Federal Funds Sold rate and the 5 year treasury has ranged from 2.44% to a negative 0.62% during the last 6 years. The spread between the Federal Funds Sold rate and the 10 year treasury has ranged from 3.60% to a negative 0.04% during the last 6 years. As a result of the compression between long and short term rates, many banks, including DNB, have seen their net interest margin fluctuate during the last 6 years.

        The table below provides, for the periods indicated, information regarding: (i) DNB's average balance sheet; (ii) the total dollar amounts of interest income from interest-earning assets and the resulting average yields (tax-exempt yields have been adjusted to a tax equivalent basis using a 34% tax rate); (iii) the total dollar amounts of interest expense on interest-bearing liabilities and the resulting average costs; (iv) net interest income; (v) net interest rate spread; and (vi) net interest margin. Average balances were calculated based on daily balances. Non-accrual loan balances are included in total loans. Loan fees and costs are included in interest on total loans.

2.    Rate / Volume Analysis

        During 2012, net interest income, before the provision for credit losses, increased $599,000 or 2.74% on a tax equivalent basis. As shown in the Rate/Volume Analysis on the following page, $639,000 was attributable to volume changes and $40,000 to rate changes. The volume changes were mostly attributable to increased levels of investment securities of $19.7 million and demand deposits of $18.2 million, offset by decreased levels of time deposits of $20.2 million. The average balance of investment securities was $172.7 million in 2012 compared to $153.0 million in 2011. The average balance of demand deposits was $80.1 million in 2012 compared to $62.0 million in 2011. The average balance of time deposits was $103.3 million in 2012 compared to $123.4 million in 2011. The decrease in yields on interest-earning assets and the decrease in rates on interest-bearing liabilities offset each other, resulting in a $40,000 unfavorable difference. The tax equivalent yield on securities increased to 2.36% in 2012 from 2.34% in 2011. The favorable change due to rate on savings deposits was $171,000 which had an average rate of 0.27% in 2012 and 0.33% in 2011. The favorable change due to rate on time deposits was $361,000 which had an average rate of 1.48% in 2012 and 1.77% in 2011. DNB's composite cost of funds decreased to 0.78% in 2012 compared to 0.93% in 2011.

        The following table sets forth, among other things, the extent to which changes in interest rates and changes in the average balances of interest-earning assets and interest-bearing liabilities have affected interest income and expense for the periods noted (tax-exempt yields have been adjusted to a tax equivalent basis using a 34% tax rate). For each category of interest-earning assets and interest-bearing liabilities, information is provided with respect to changes attributable to (i) changes in rate (change in rate multiplied by old volume) and (ii) changes in volume (change in volume multiplied by new rate). The net change attributable to the combined impact of rate and volume has been allocated proportionately to the change due to rate and the change due to volume.

3.    Interest Rate Sensitivity Analysis

        The largest component of DNB's total income is net interest income, and the majority of DNB's financial instruments are comprised of interest rate-sensitive assets and liabilities with various terms and maturities. The primary objective of management is to maximize net interest income while minimizing interest rate risk. Interest rate risk is derived from timing differences in the re-pricing of assets and liabilities, loan prepayments, deposit withdrawals, and differences in lending and funding rates. The Asset/Liability Committee ("ALCO") actively seeks to monitor and control the mix of interest rate-sensitive assets and interest rate-sensitive liabilities.

        ALCO continually evaluates interest rate risk management opportunities, including the use of derivative financial instruments. Management believes that hedging instruments currently available are not cost-effective, and therefore, has focused its efforts on increasing DNB's spread by attracting lower-costing retail deposits and in some instances, borrowing from the FHLB of Pittsburgh.

        DNB reports its callable agency investments ($35.5 million at December 31, 2012) and callable FHLBP advances ($20.0 million at December 31, 2012) at their Option Adjusted Spread ("OAS") effective duration date, as opposed to the call or maturity date. In management's opinion, using effective duration dates on callable securities and advances provides a better estimate of the option exercise date under any interest rate environment. The OAS methodology is an approach whereby the likelihood of option exercise takes into account the coupon on the security, the distance to the call date, the maturity date and current interest rate volatility. In addition, prepayment assumptions derived from historical data have been applied to mortgage-related securities, which are included in investments. (See additional discussion in Item 7a. Quantitative and Qualitative Disclosures About Market Risk on page 45 of this Form 10-K.)

B.    Liquidity and Market Risk Management

        Liquidity is the ability to meet current and future financial obligations. The Bank further defines liquidity as the ability to respond to deposit outflows as well as maintain flexibility to take advantage of lending and investment opportunities. The Bank's primary sources of funds are operating earnings, deposits, repurchase agreements, principal and interest payments on loans, proceeds from loan sales, sales and maturities of mortgage backed and investment securities, and FHLBP advances. The Bank uses the funds generated to support its lending and investment activities as well as any other demands for liquidity such as deposit outflows. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows, mortgage prepayments, loan and security sales and the exercise of call features are greatly influenced by general interest rates, economic conditions and competition.

        The objective of DNB's asset/liability management function is to maintain consistent growth in net interest income within DNB's policy limits. This objective is accomplished through the management of liquidity and interest rate risk, as well as customer offerings of various loan and deposit products. DNB maintains adequate liquidity to meet daily funding requirements, anticipated deposit withdrawals, or asset opportunities in a timely manner. Liquidity is also necessary to meet obligations during unusual, extraordinary or adverse operating circumstances, while avoiding a significant loss or cost. DNB's foundation for liquidity is a stable deposit base as well as a marketable investment portfolio that provides cash flow through regular maturities or that can be used for collateral to secure funding in an emergency. As part of its liquidity management, DNB maintains assets, which comprise its primary liquidity (Federal funds sold, investments and interest-bearing cash balances, less pledged securities).

C.    Credit Risk Management

        DNB defines credit risk as the risk of default by a customer or counter-party. The objective of DNB's credit risk management strategy is to quantify and manage credit risk on an aggregate portfolio basis as well as to limit the risk of loss resulting from an individual customer default. Credit risk is managed through a combination of underwriting, documentation and collection standards. DNB's credit risk

Table of Contents

management strategy calls for regular credit examinations and quarterly management reviews of large credit exposures and credits experiencing credit quality deterioration. DNB's loan review procedures provide objective assessments of the quality of underwriting, documentation, risk grading and charge-off procedures, as well as an assessment of the allowance for credit loss reserve analysis process. As the U.S. economy moves through a period of recession, it is possible that delinquencies and non-performing assets may rise as the value of homes decline and DNB's borrowers experience financial difficulty due to corporate downsizing, reduced sales, or other negative events which will impact their ability to meet their contractual loan payments. To minimize the impact on DNB's earnings and maintain sound credit quality, management continues to aggressively monitor credit and credit relationships that may be impacted by such adverse factors.

D.    Competition

        In addition to the challenges related to the interest rate environment, community banks in Chester and Delaware Counties have been experiencing increased competition from large regional and international banks entering DNB's marketplace through mergers and acquisitions. Competition for loans and deposits has negatively affected DNB's net interest margin. To compensate for the increased competition, DNB, along with other area community banks, has aggressively sought and marketed customers who have been disenfranchised by these mergers.

        To attract these customers, DNB has introduced new deposit products and services, such as Choice Checking with ATM surcharge rebates, Mobile Banking, Popmoney® and expanded bill payment functionality with CheckFree®. DNB also offers a complete package of cash management services including remote deposit, ARP services, ACH, government account services and more. In addition, our Free Business Checking products provide significant advantages to our customers when compared to those offered by our competitors.

        None.

VI.   Critical Accounting Policies and Estimates

        The following discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. Generally accepted accounting principles are complex and require management to apply significant judgment to various accounting, reporting and disclosure matters. Management must use assumptions and estimates to apply these principles where actual measurement is not possible or practical. Actual results may differ from these estimates under different assumptions or conditions.

        In management's opinion, the most critical accounting policies and estimates impacting DNB's consolidated financial statements are listed below. These policies are critical because they are highly dependent upon subjective or complex judgments, assumptions and estimates. Changes in such estimates may have a significant impact on the financial statements. For a complete discussion of DNB's significant accounting policies, see the footnotes to the Consolidated Financial Statements and discussion throughout this Form 10-K.

1.    Determination of the allowance for credit losses.    Credit loss allowance policies involve significant judgments, estimates and assumptions by management which may have a material impact on the carrying value of net loans and, potentially, on the net income recognized by DNB from period to period. The allowance for credit losses is based on management's ongoing evaluation of the loan and lease portfolio and reflects an amount considered by management to be its best estimate of the amount necessary to absorb known and inherent losses in the portfolio. Management considers a variety of factors when establishing the allowance, such as the impact of current economic conditions, diversification of the portfolios, delinquency statistics, results of loan review and related classifications, and historic loss rates. In addition, certain individual loans which management has identified as problematic are specifically provided for, based upon an evaluation of the borrower's perceived ability to pay, the estimated adequacy of the underlying collateral and other relevant factors. In addition, regulatory authorities, as an integral part of their examinations, periodically review the allowance for credit losses. They may require additions to the allowance based upon their judgments about information available to them at the time of examination. Although provisions have been established and segmented by type of loan, based upon management's assessment of their differing inherent loss characteristics, the entire allowance for credit losses is available to absorb further losses in any category.

        Management uses significant estimates to determine the allowance for credit losses. Because the allowance for credit losses is dependent, to a great extent, on conditions that may be beyond DNB's control, management's estimate of the amount necessary to absorb credit losses and actual credit losses could differ. DNB's current judgment is that the allowance for credit losses remains appropriate at December 31, 2012.

VII. 2012 Financial Results

A.    Liquidity

        Management maintains liquidity to meet depositors' needs for funds, to satisfy or fund loan commitments, and for other operating purposes. DNB's foundation for liquidity is a stable and loyal customer deposit base, cash and cash equivalents, and a marketable investment portfolio that provides periodic cash flow through regular maturities and amortization, or that can be used as collateral to secure funding. Primary liquidity includes investments, Federal funds sold, and interest-bearing cash balances, less pledged securities. DNB also anticipates scheduled payments and prepayments on its loan and mortgage- backed securities portfolios. In addition, DNB maintains borrowing arrangements with various correspondent banks, the Federal Home Loan Bank of Pittsburgh and the Federal Reserve Bank of Philadelphia to meet short-term liquidity needs. Through these relationships, DNB has available credit of approximately $195.2 million at December 31, 2012. Management believes that DNB has adequate resources to meet its short-term and long-term funding requirements.

        As of December 31, 2012, deposits totaled $530.4 million, up $32.9 million from $497.5 million at December 31, 2011. There were $61.1 million in certificates of deposit (including IRAs) scheduled to mature during the next twelve months. At December 31, 2012, DNB had $67.8 million in un-funded loan commitments. In addition, there was $2.1 million in un-funded letters of credit. Management anticipates the majority of these commitments will be funded by means of normal cash flows.

        For detailed information regarding the maturity of our time deposits and certificates of deposit, see Note 6 to our Consolidated Financial Statements beginning at page 67.

Capital Resources and Adequacy

        Stockholders' equity was $56.7 million at December 31, 2012 compared to $51.1 million at December 31, 2011. The increase in stockholders' equity was primarily a result of 2012 earnings of $5.2 million and $793,000 of net-of-tax other comprehensive income. These additions to stockholders equity were partially offset by $543,000 of dividends paid on DNB's common stock and $315,000 of dividends paid on DNB's Non-Cumulative Perpetual Preferred Stock, Series 2011A. During the first quarter of 2012, DNB paid the Treasury dividends of $135,000, applicable to the fourth quarter of 2011. (See Note 16 regarding DNB's participation in the Treasury's Small Business Lending Fund program ("SBLF"), a $30 billion fund established under the Small Business Jobs Act of 2010.)

        On January 30, 2009, as part of the Capital Purchase Program ("CPP") of the Emergency Economic Stabilization Act of 2008 administered by the United States Department of the Treasury ("the Treasury"), DNB entered into a Letter Agreement and a Securities Purchase Agreement with the Treasury, pursuant to which DNB issued and sold on January 30, 2009, and the Treasury purchased for cash on that date (i) 11,750 shares of DNB's Fixed Rate Cumulative Perpetual Preferred Stock, Series 2008A, par value $10.00 per share, having a liquidation preference of $1,000 per share ("the CPP Shares"), and (ii) a ten-year warrant to purchase up to 186,311 shares of DNB's common stock, $1.00 par value, at an exercise price of $9.46 per share, for an aggregate purchase price of $11,750,000 in cash. This transaction closed on January 30, 2009. The issuance and sale of these securities was a private placement exempt from registration pursuant to Section 4(2) of the Securities Act of 1933. The Bank provided dividends to DNB in connection with the $11,750,000 of Fixed Rate Cumulative Perpetual Preferred Stock sold on January 30, 2009 as part of the CPP through its redemption in 2011. On September 21, 2011, DNB entered into the Warrant Letter Agreement with the Treasury. Pursuant to the Warrant Letter Agreement, DNB Financial Corporation repurchased from Treasury the warrant to purchase 186,311 shares of DNB Financial Corporation's common stock issued to Treasury in January 2009 under CPP. DNB Financial Corporation paid a purchase price of $458,000 for the warrant.

        On August 4, 2011, DNB entered into a Securities Purchase Agreement with the Secretary of the Treasury, pursuant to which DNB issued and sold to the Treasury 13,000 shares of its Non-Cumulative Perpetual Preferred Stock, Series 2011A ("Series 2011A Preferred Stock"), having a liquidation preference of $1,000 per share for aggregate proceeds of $13,000,000. The Securities Purchase Agreement was entered into, and the Series 2011A Preferred Stock was issued, pursuant to the Treasury's Small Business Lending Fund program ("SBLF"), a $30 billion fund established under the Small Business Jobs Act of

2010, that encourages lending to small businesses by providing capital to qualified community banks with assets of less than $10 billion. Of the $13 million in aggregate proceeds, $11,879,000 was used to repurchase all CPP Shares ($11,750,000 was paid in principal and $128,900 in accrued, unpaid dividends related to the CPP Shares) previously held by the Treasury. The securities sold in this transaction were exempt from registration under Section 4(2) of the Securities Act of 1933, as amended, as a transaction by DNB not involving a public offering.

        Management believes that DNB and the Bank have each met the definition of "well capitalized" for regulatory purposes on December 31, 2012. The Bank's capital category is determined for the purposes of applying the bank regulators' "prompt corrective action" regulations and for determining levels of deposit insurance assessments and may not constitute an accurate representation of DNB's or the Bank's overall financial condition or prospects. DNB's capital exceeds the Federal Reserve Bank's ("FRB's") minimum leverage ratio requirements for bank holding companies (see additional discussion in Regulatory Matters — Note 16 to DNB's consolidated financial statements).

        Under federal banking laws and regulations, DNB and the Bank are required to maintain minimum capital as determined by certain regulatory ratios. Capital adequacy for regulatory purposes, and the capital category assigned to an institution by its regulators, may be determinative of an institution's overall financial condition.

B.    Results of Operations

1.    Summary of Performance

(a)    Summary of Results

        For the year ended December 31, 2012, DNB reported net income of $5.2 million versus $4.9 million for 2011. Per share earnings on a fully diluted basis were $1.79, up from $1.53 for the prior year. The global and U.S. economies have experienced reduced business activity as a result of disruptions in the financial system during the past four years. The United States, Europe and many other countries across the globe are struggling with too much debt and weaker streams of revenues as a result of recessionary pressures and high unemployment. Overall economic growth continues to be slow and national and regional unemployment rates remain at elevated levels. The risks associated with our business remain acute in periods of slow economic growth and high unemployment. Moreover, financial institutions continue to be affected by a sluggish real estate market and constrained financial markets. While we are continuing to take steps to decrease and limit our exposure to problem loans, we nonetheless retain direct exposure to the residential and commercial real estate markets, and we are affected by these events.

        The January 16, 2013 Beige Book indicated that residential builders in the Third Federal Reserve District (the "Third District"), the District where DNB is located, reported slight year-over-year growth during 2012. Residential brokers reported robust year-over-year sales growth, with steady year-end momentum. As with new home construction, existing home sales are growing from a low base. Builders and, to a greater extent, brokers are optimistic that recent growth will be sustained in 2013.

        The January 16, 2013 Beige Book indicates that there has been renewed modest growth in overall leasing activity and continued slight growth in construction. Leasing activity finished 2012 with sustained double-digit growth. Stronger employment growth of professional services is credited with much of the demand; however, that demand is partially offset, as existing firms are consolidating and adjusting to more efficient overall office spaces with smaller square footage per person. The Third District's nonresidential real estate contacts retain an outlook of slow and steady growth.

        Optimism among Third District manufacturers that business conditions will improve during the next six months has rebounded strongly since the November 28, 2012 Beige Book and is evident across nearly all sectors. Companies have also significantly raised their overall expectations of future hiring and their plans for capital spending since the November 28, 2012 Beige Book. Since the November 28, 2012 Beige

Book, Third District manufacturers have reported that orders and shipments have recovered to a pace of slight growth. The mild pace can be partially attributed to seasonal trends. Makers of food products, lumber and wood products, primary metals, fabricated metal products, and instruments have reported gains since the November 28, 2012 Beige Book. Lower activity was reported by makers of industrial machinery and electronic equipment.

        The overall outlook of the Third District's business contacts, many of which have business models similar to DNB's small business clients, is considerably more optimistic relative to the views expressed in the November 28, 2012 Beige Book. They reported underlying strength in many sectors and expressed relief that part of the fiscal cliff dilemma has been resolved. Contacts from virtually all sectors reported greater expectations of future growth than views expressed in the November 28, 2012 Beige Book. Plans for future hiring were also significantly more expansive. Most contacts continued to express concerns over the impact from the recent payroll tax increase and the remaining potential budget cuts that might reduce demand.

        Although DNB's earnings have been impacted by the general economic conditions, the impact has not been as severe as it has been in many parts of the nation, due to a relatively healthier economic climate in the Third Federal Reserve District and specifically Chester County. DNB's franchise spans both Chester and Delaware counties in southeastern Pennsylvania. The majority of loans have been made to businesses and individuals in Chester County and the majority of deposits are from businesses and individuals within the County. According to census data, Chester County's population has grown at approximately 15%, compared to 13% for the nation and 3% for the Commonwealth of Pennsylvania. The median household income in Chester County is $72,288 and the County ranks 14th nationally in disposable income. The unemployment rate for Chester County stood at 5.7% as of May 2012, compared to a Pennsylvania unemployment rate of 7.3% and a national unemployment rate of 7.9%. Traditionally, the unemployment rate has been the lowest in the surrounding five-county area and it ranks among the lowest unemployment rates in the Commonwealth. Chester County has a civilian labor force of 266,100, with manufacturing jobs representing 23.1% of the workforce and retail shopping comprising 13.8% of the total employment. During the last few years, the County has been able to keep most of its major employers, however some of them have downsized in order to remain competitive. Chester County is home to several Fortune 500 companies. Thirteen Chester County employers have 1,000 employees or more. Of these 13 companies, two companies have more than 5,000 employees.

        As the U.S. and local economy moves through a period of reduced business activity and historically high unemployment rates, delinquencies will rise as the value of homes decline and DNB's borrowers experience financial difficulty due to corporate downsizing, reduced sales, or other negative events which may impact their ability to meet their contractual loan payments. As a result of continued negative trends in the economy and their impact on our borrowers' ability to repay their loans, DNB made a $1.5 million provision for credit losses during the year ended December 31, 2012.

        These and other factors have impacted our operations. We continue to focus on the consistency and stability of core earnings and balance sheet strength which are critical success factors in today's challenging economic environment.

(b)    Significant Events, Transactions and Economic Changes Affecting Results

        Some of DNB's significant events during 2012 include:

•

Total loans and leases were $396.5 million at December 31, 2012, down $7.2 million or 1.8% from 2011. DNB's total loans declined due to historically high pay-downs in the commercial loan portfolio, precipitated by historically low rates and aggressive competition for such loans in DNB's market area. Gross loans funded during 2012 were $89.7 million compared to $78.7 million in 2011. Paydowns on loans were $96.9 million, up 36.1% from $71.2 million in 2011. Commercial loans declined by $7.0 million or 6.9% to $94.1 million, while commercial mortgage loans grew

$1.9 million or 0.82% to $234.2 million. Residential mortgage and consumer loans remained relatively flat.

•

Positive trends were observed for the year ended December 31, 2012, in two key business lines that contribute to total non-interest income. Service charges on deposits increased 18.9% or $216,000 and wealth management fees increased 31.6% or $248,000 when compared to the same period in 2011.



•

On June 11, 2012, The Bank acquired one full-service branch office located in Boothwyn, Pennsylvania. The Bank purchased specified assets of the branch, including personal loans totaling $66,000, real estate, furniture and equipment totaling $670,000 and assumed approximately $15.9 million of deposits.

(d)    Material Changes in Results

        Please refer to the discussion above in the section titled "Significant Events, Transactions and Economic Changes Affecting Results."

(e)    Effect of Inflation and Changing Rates

        For detailed discussion of the effects of inflation and changes in rates on DNB's results, refer to the discussion below on "Net Interest Income."

2.    Net Interest Income

        DNB's earnings performance is primarily dependent upon its level of net interest income, which is the excess of interest income over interest expense. Interest income includes interest earned on loans and leases (net of interest reversals on non-performing loans), investments and Federal funds sold, as well as net loan fee amortization and dividend income. Interest expense includes the interest cost for deposits, FHLBP advances, repurchase agreements, corporate debentures, Federal funds purchased and other borrowings.

        During the year ended December 31, 2012, management focused on strengthening DNB's net interest margin, as well as reducing our composite cost of funds. The composite cost of funds for the year ended December 31, 2012 was 0.78% compared to 0.93% in 2011. The net interest margin for the year ended December 31, 2012 was 3.78% compared to 3.72% in 2011. Management continued to actively manage deposits during 2012 to reduce DNB's cost of funds. Time deposits decreased $2.9 million to $102.3 million at December 31, 2012 compared to $105.2 million at December 31, 2011. Transaction and savings accounts, which are generally lower costing deposits, increased $35.8 million during the year ended December 31, 2012.

        Interest on loans and leases was $21.9 million for 2012, compared to $22.7 million for 2011. The average balance of loans and leases was $400.7 million with an average tax equivalent yield of 5.52% in 2012 compared to $408.8 million with an average tax equivalent yield of 5.60% in 2011.

        Interest and dividends on investment securities was $3.8 million and $3.5 million for 2012 and 2011, respectively. The average balance of investment securities was $173.0 million with an average tax equivalent yield of 2.36% in 2012 compared to $153.0 million with an average tax equivalent yield of 2.34% in 2011. Total investment securities increased $57.4 million from December 31, 2011 to December 31, 2012 primarily due to purchases of $126.9 million of securities during 2012, offset by $70.3 million of sales,

maturities, calls and pay-downs during 2012. Interest and dividends increased $300,000, primarily due to a higher average balance of securities.

        Interest on deposits was $2.4 million for 2012 compared to $3.2 million for 2011. The average balance of interest-bearing deposits was $431.2 million with an average rate of 0.56% for 2012 compared to $441.5 million with an average rate of 0.73% for 2011. The decrease in rate during both periods was primarily attributable to a lower interest rate environment.

        Interest on FHLBP advances was $848,000 for 2012 compared to $864,000 for 2011. The average balance on FHLBP advances was $20.0 million with an average rate of 4.23% for 2012 compared to $20.3 million with an average rate of 4.25% for 2011.

        Interest on repurchase agreements was $71,000 for 2012 compared to $142,000 for 2011. The average balance on repurchase agreements was $20.4 million with an average rate of 0.34% for 2012 compared to $26.0 million with an average rate of 0.55% for 2011. The decrease in interest expense was primarily the result of the lower interest rate environment, coupled with lower average balances during 2012.

3.    Provision for Credit Losses

        To provide for known and inherent losses in the loan and lease portfolio, DNB maintains an allowance for credit losses. There was a $1.5 million provision made in both 2012 and 2011. For a detailed discussion on DNB's reserve methodology, refer to "Item 1 — Determination of the allowance for credit losses" which can be found under "Critical Accounting Policies and Estimates".

4.    Non-Interest Income

        Non-interest income includes service charges on deposit products; fees received in connection with the sale of non-depository products and services, including fiduciary and investment advisory services offered through DNB First Wealth Management; securities brokerage products and services and insurance products and services offered through DNB Investments & Insurance; and other sources of income such as increases in the cash surrender value of Bank Owned Life Insurance ("BOLI"), net gains on sales of investment securities and SBA loans. In addition, DNB receives fees for cash management, remote capture, merchant services, debit cards, safe deposit box rentals and similar activities.

        Non-interest income was $4.5 million for 2012 compared to $3.7 million for 2011. The $862,000 increase was primarily due to a $380,000 increase in gains on the sale of investments, a $248,000 increase in Wealth Management fees, a $216,000 increase in service charges on deposits and a $145,000 increase in other income. These increases were offset by a $123,000 decrease in gains on sales of SBA loans.

5.    Non-Interest Expense

        Non-interest expense includes salaries & employee benefits, furniture & equipment, occupancy, professional & consulting fees as well as marketing, printing & supplies, FDIC insurance, PA shares tax, telecommunications, write-downs on other real estate owned ("OREO") and other repossessed property and other less significant expense items. Non-interest expenses increased during 2012 by $954,000 or 5.7% over 2011. During 2012, DNB had $440,000 of write-downs on OREO properties and other assets that it held compared to $23,000 of such write-downs during 2011. Absent these write-downs, non-interest expenses increased $537,000 or 3.21% year over year.

        Salary and employee benefits.    Salary and employee benefits were $9.0 million for 2012 compared to $8.8 million for 2011. The $233,000 increase was attributable to a higher level of full-time equivalent employees year over year, primarily due to the acquisition of the branch in Boothwyn, Pennsylvania as well as a higher level of incentive based compensation in DNB's Wealth Management area.

32

Table of Contents

        Professional and Consulting.    Professional and consulting expense was $1.3 million for 2012 compared to $1.1 million for 2011. The increase was primarily attributable to higher levels of legal fees associated with credit administration.

        Other expenses.    Other expenses was $1.8 million for 2012 compared to $1.6 million for 2011. The $247,000 increase was primarily due to $65,000 of one-time conversion costs associated with the Boothwyn branch conversion in the second quarter of 2012. There were also increased expenses for unfunded loan provision and donations.

        FDIC insurance.    FDIC insurance expense was $470,000 in 2012 compared to $562,000 in 2011. The $92,000 decrease was primarily due to changes adopted by the FDIC, effective April 1, 2011, to its base and risk-based deposit insurance rates. Pursuant to the new rules, DNB's annual assessment base rates were based on the bank's risk category. Prior to the FDIC adopting these new assessment base rates, insurance premiums were primarily based on the level of DNB's insured deposits. (See "Deposit Insurance Assessments" on page 10 of this Form 10-K)

        Write-down of OREO and other repossessed property.    During 2012, DNB had $440,000 of write-downs on OREO and other repossessed property that it held compared to $23,000 of such write-downs during 2011. At December 31, 2012, DNB held $1.2 million of such assets, compared to $4.0 million at December 31, 2011. Prior to the filing of this Form 10-K, DNB reported such write-downs as an adjustment to non-interest income in filings with the SEC for 2011 and 2012.

6.    Income Taxes

        Income tax expense was $2.1 million for both 2012 and 2011. Income tax expense for each period primarily differs from the amount determined at the statutory rate of 34.0% due to tax-exempt income on loans and investment securities, DNB's ownership of BOLI policies and tax credits recognized on a low-income housing limited partnership. The effective tax rates for 2012 and 2011 were 28.7% and 29.6%, respectively. The lower effective tax in 2012 was primarily due to higher levels of tax-exempt investment securities in 2012, compared to 2011.

Financial Condition Analysis

1.    Investment Securities

        DNB's investment portfolio consists of US agency securities, mortgage-backed securities issued by US Government agencies, collateralized mortgage obligations, state and municipal securities, bank stocks, and other bonds and notes. In addition to generating revenue, DNB maintains the investment portfolio to manage interest rate risk, provide liquidity, provide collateral for borrowings and to diversify the credit risk of earning assets. The portfolio is structured to maximize DNB's net interest income given changes in the economic environment, liquidity position and balance sheet mix.

        Given the nature of the portfolio, and its generally high credit quality, management normally expects to realize all of its investment upon the maturity of such instruments. Management determines the appropriate classification of securities at the time of purchase. Investment securities are classified as: (a) securities held to maturity ("HTM") based on management's intent and ability to hold them to maturity; (b) trading account ("TA") securities that are bought and held principally for the purpose of selling them in the near term; and (c) securities available for sale ("AFS"). DNB does not currently maintain a trading account portfolio.

        Securities classified as AFS include securities that may be sold in response to changes in interest rates, changes in prepayment assumptions, the need to increase regulatory capital or other similar requirements. DNB does not necessarily intend to sell such securities, but has classified them as AFS to provide flexibility to respond to liquidity needs.

Table of Contents

        DNB's investment portfolio (HTM and AFS securities) totaled $201.3 million at December 31, 2012, up $57.4 million or 39.8% from $144.0 million at December 31, 2011.

        As of June 16, 2011, DNB reclassified 3 mortgage backed securities and 2 collateralized mortgage obligations with book values (net carrying amount) of $12.5 million and $7.7 million, respectively, from available-for-sale (AFS) to held-to-maturity (HTM). Reclassifying these 5 securities to HTM will reduce the volatility and possible future negative effect on DNB's capital ratios, because HTM securities are not marked-to-market through other comprehensive income, but carried at their amortized cost basis. In addition, the 5 securities that were reclassified to HTM will continue to produce strong cash flows for DNB's operating and funding needs. The fair value of the 3 mortgage backed securities and 2 collateralized mortgage obligations was $12.4 million and $7.7 million, respectively at June 16, 2011, the date of their reclassification. The $116,000 difference between their book value and their fair value will be amortized as an adjustment to the carrying value of the investment securities over the remaining lives, which is estimated to be 2.3 years. There were no such reclassifications in 2012.

        At December 31, 2012, approximately 67% of DNB's investments were in the AFS portfolio and 33% were in the HTM portfolio. Investments consist mainly of mortgage-backed securities and Agency notes backed by government sponsored enterprises, such as FHLMC, FNMA and FHLB. Management regularly reviews its investment portfolio to determine whether any securities are other than temporarily impaired. DNB did not invest in securities backed by sub-prime mortgages. At December 31, 2012, the combined AFS and HTM portfolios had an unrealized pretax gain of $4.0 million and an unrealized pretax loss of $434,000. At December 31, 2011, the combined AFS and HTM portfolios had an unrealized pretax gain of $2.2 million and an unrealized pretax loss of $926,000. There were no other than temporarily impaired securities.

        The following tables set forth information regarding the composition, stated maturity and average yield of DNB's investment security portfolio as of the dates indicated (tax-exempt yields have been adjusted to a tax equivalent basis using a 34% tax rate). The first two tables do not include amortization or anticipated prepayments on mortgage-backed securities. Callable securities are included at their stated maturity dates.

2.    Loan and Lease Portfolio

        DNB's loan and lease portfolio consists primarily of commercial and residential real estate loans, commercial loans and lines of credit (including commercial construction), commercial leases and consumer loans. The portfolio provides a stable source of interest income, monthly amortization of principal and, in the case of adjustable rate loans, re-pricing opportunities.

        Total loans and leases were $396.5 million at December 31, 2012, down $7.2 million or 1.8% from 2011. DNB's total loans declined due to historically high pay-downs in the commercial loan portfolio, precipitated by historically low rates and aggressive competition for such loans in DNB's market area. Gross loans funded during 2012 were $89.7 million compared to $78.7 million in 2011. Paydowns on loans were $96.9 million, up from $71.2 million in 2011. Commercial loans declined by $7.0 million or 6.9% to $94.1 million, while commercial mortgage loans grew $1.9 million or 0.82% to $234.2 million. Residential mortgage and consumer loans remained relatively flat, primarily due to the current economic environment, which has lessened consumer demand for home equity loan products as a result of falling housing prices and a higher unemployment rate.

3.    Non-Performing Assets

        Total non-performing assets increased $55,000 to $11.7 million at December 31, 2012, compared to $11.6 million at December 31, 2011. The $55,000 increase was attributable to a $2.1 million increase in non-performing loans, a $659,000 increase in loans 90 days past due and still accruing, offset by a $2.7 million reduction in other real estate owned & other repossessed property. As a result of the increase in non-performing loans and a $7.2 million net decrease in gross loans, the non-performing loans to total loans ratio increased to 2.63% at December 31, 2012, from 1.89% at December 31, 2011. The non-performing assets to total assets ratio decreased to 1.82% at December 31, 2012 from 1.91% at December 31, 2011. The allowance to non-performing loans ratio decreased to 65.5% at December 31, 2012 from 80.7% at December 31, 2011. DNB continues to work diligently to improve asset quality by adhering to strict underwriting standards and improving lending policies and procedures. Non-performing assets have, and will continue to have, an impact on earnings; therefore management intends to continue working aggressively to reduce the level of such assets.

        Non-performing assets are comprised of non-accrual loans and leases, loans and leases delinquent over ninety days and still accruing, troubled debt restructurings ("TDRs") as well as Other Real Estate

Table of Contents

Owned ("OREO") and other repossessed property. Non-accrual loans and leases are loans and leases for which the accrual of interest ceases when the collection of principal or interest payments is determined to be doubtful by management. It is the policy of DNB to discontinue the accrual of interest when principal or interest payments are delinquent 90 days or more (unless the loan principal and interest are determined by management to be fully secured and in the process of collection), or earlier if considered prudent. Interest received on such loans is applied to the principal balance, or may, in some instances, be recognized as income on a cash basis. A non-accrual loan or lease may be restored to accrual status when management expects to collect all contractual principal and interest due and the borrower has demonstrated a sustained period of repayment performance in accordance with the contractual terms. OREO consists of real estate acquired by foreclosure. Other repossessed property are primarily assets from DNB's commercial lease portfolio that were repossessed. OREO and other repossessed property are carried at the lower of cost or estimated fair value, less estimated disposition costs. Any significant change in the level of non-performing assets is dependent, to a large extent, on the economic climate within DNB's market area.

        DNB's Credit Policy Committee monitors the performance of the loan and lease portfolio to identify potential problem assets on a timely basis. Committee members meet to design, implement and review asset recovery strategies, which serve to maximize the recovery of each troubled asset. As of December 31, 2012, DNB had $14.2 million of loans classified as substandard, which, although performing at that date, are believed to require increased supervision and review; and may, depending on the economic environment and other factors, become non-performing assets in future periods. The amount of such loans at December 31, 2011 was $9.2 million. The majority of the loans are secured by commercial real estate, with lesser amounts being secured by residential real estate, inventory and receivables.

        The following table sets forth those assets that are: (i) placed on non-accrual status, (ii) contractually delinquent by 90 days or more and still accruing, (iii) troubled debt restructurings other than those included in items (i) and (ii), and (iv) OREO as a result of foreclosure or voluntary transfer to DNB as well as other repossessed property.

Table of Contents

        Included in the loan portfolio are loans for which DNB has ceased the accrual of interest (i.e. non-accrual loans). Loans of approximately $9.6 million and $7.4 million as of December 31, 2012 and 2011, respectively, were on a non-accrual basis. DNB also had loans of approximately $869,000 and $210,000 that were 90 days or more delinquent, but still accruing, as of December 31, 2012 and 2011, respectively. If contractual interest income had been recorded on non-accrual loans, interest would have been increased as shown in the following table:

4.    Allowance for Credit Losses

        To provide for known and inherent losses in the loan and lease portfolios, DNB maintains an allowance for credit losses. Provisions for credit losses are charged against income to increase the allowance when necessary. Loan and lease losses are charged directly against the allowance and recoveries on previously charged-off loans and leases are added to the allowance. In establishing its allowance for credit losses, management considers the size and risk exposure of each segment of the loan and lease portfolio, past loss experience, present indicators of risk such as delinquency rates, levels of non-accruals, the potential for losses in future periods, and other relevant factors. Management's evaluation of criticized and classified loans generally includes reviews of borrowers of $100,000 or greater. Consideration is also given to examinations performed by regulatory agencies, primarily the Office of the Comptroller of the Currency ("OCC").

        Management reviews and establishes the adequacy of the allowance for credit losses in accordance with U.S. generally accepted accounting principles, guidance provided by the Securities and Exchange Commission and as prescribed in OCC Bulletin 2006-47. Its methodology for assessing the appropriateness of the allowance consists of several key elements which include: specific allowances for identified impaired loans; and allowances by loan type for pooled homogenous loans. In considering national and local economic trends, we review a variety of information including Federal Reserve publications, general economic statistics, foreclosure rates and housing statistics published by third parties. We believe this improves the measure of inherent loss over a complete economic cycle and reduces the impact for qualitative adjustments. The unallocated portion of the allowance is intended to provide for probable losses not otherwise accounted for in management's other elements of its overall estimate. An unallocated component is maintained to cover uncertainties such as changes in the national and local economy, concentrations of credit, expansion into new markets and other factors that could affect management's estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

        In addition, DNB reviews historical loss experience for the commercial real estate, commercial, residential real estate, home equity and consumer installment loan pools to determine a historical loss factor. The historical loss factors are then applied to the current portfolio balances to determine the required reserve percentage for each loan pool based on risk rating. Historical losses are segregated into risk-similar groups and a loss ratio is determined for each group over a three year period. The three year average loss ratio by type is then used to calculate the estimated loss based on the current balance of each group. This three year time period is appropriate given DNB's historical level of losses and, more importantly, represents the current economic environment.

Table of Contents

        This analysis is intended to assess the potential for loss within the loan portfolio and to substantiate the adequacy of the allowance. Should the analysis indicate that the allowance is not adequate, management will recommend a provision expense be made in an amount equal to the shortfall derived. In establishing and reviewing the allowance for adequacy, emphasis has been placed on utilizing the methodology prescribed in OCC Bulletin 2006-47. Management believes that the following factors create a comprehensive system of controls in which management can monitor the quality of the loan portfolio. Consideration has been given to the following factors and variables which may influence the risk of loss within the loan portfolio:

•

Changes in the nature and volume of the portfolio and in the terms of loans



•

Changes in the volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or graded loans



•

The existence and effect of any concentrations of credit, and changes in the level of such concentrations



•

Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses



•

Changes in the experience, ability, and depth of lending management and other relevant staff



•

Changes in the quality of the institution's loan review system



•

Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments



•

The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution's existing portfolio



•

Changes in the value of underlying collateral for collateral-dependent loans

        Portfolio risk includes the levels and trends in delinquencies, impaired loans, changes in the loan rating matrix and trends in volume and terms of loans. Management is satisfied with the stability of the past due and non-performing loans and believes there has been no further decline in the quality of the loan portfolio due to any trend in delinquent or adversely classified loans. In determining the adequacy of the allowance, management considered the deterioration of asset quality in DNB's commercial mortgage and residential first mortgage portfolios, which were factors contributing to the increase in the level of allowance during 2012 and 2011. In addition to ordering new appraisals and creating specific reserves on impaired loans, the allowance allocation rates were increased, reflective of delinquency trends which have been caused by continued weakness in the housing markets, falling home equity values, and rising unemployment. New appraisal values we have obtained for existing loans have generally been consistent with trends indicated by Case-Schiller and other indices.

        Given the contraction in real estate values, DNB closely monitors the loan to value ratios of all classified assets and requires periodic current appraisals to monitor underlying collateral values. Management also reviews borrower, sponsorship and guarantor's financial strength along with their ability and willingness to provide financial support of their obligations on an immediate and continuing basis.

        The provision remained flat at $1.5 million in 2012, compared to 2011. DNB's percentage of allowance for credit losses to total loans and leases was 1.72% at December 31, 2012 compared to 1.53%, 1.49%, and 1.52% for the years ended December 31, 2011, 2010 and 2009, respectively. Management monitors DNB's performance metrics including those ratios related to non-performing loans and leases. The allowance as a percentage of total loans and leases has increased over the last five years from 1.36% at December 31, 2008 to 1.72% at December 31, 2012, precipitated by the increase in non-performing assets since 2008 ($7.7 million, $13.7 million, $11.5 million, $11.6 million and $11.7 million at December 31, 2008,

2009, 2010, 2011 and 2012, respectively.) Net charge-offs were $781,000 in 2012 compared to $1.2 million and $1.8 million in 2011 and 2010, respectively. The percentage of net charge-offs to total average loans and leases were 0.20%, 0.29%, and 0.49% during the three years ending December 31, 2012, 2011, and 2010, respectively. Management is not aware of any potential problem loans, which were accruing and current at December 31, 2012, where serious doubt exists as to the ability of the borrower to comply with the present repayment terms and that would result in a significant loss to DNB.

        The increase in the allowance for loan loss ratio reflects management's estimate of the level of inherent losses in the portfolio, which continued to increase during 2012 due to a recessionary economy, continued high unemployment, a weakened housing market and deterioration in income-producing properties.

        We typically establish a general valuation allowance on classified loans which are not impaired. In establishing the general valuation allowance, we segregate these loans by category. The categories used by DNB include "doubtful," "substandard," "special mention," "watch list" and "pass." For commercial and construction loans, the determination of the category for each loan is based on periodic reviews of each loan by our lending and credit officers as well as an independent, third-party consultant. The reviews include a consideration of such factors as recent payment history, current financial data, cash flow, financial projections, collateral evaluations, guarantor or sponsorship financial strength and current economic and business conditions. Categories for mortgage and consumer loans are determined through a similar review. Classification of a loan within a category is based on identified weaknesses that increase the credit risk of loss on the loan. Each category carries a loss factor for the allowance percentage to be assigned to the loans within that category. The allowance percentage, is determined based on inherent losses associated with each type of lending as determined through consideration of our loss history with each type of loan, trends in credit quality and collateral values, and an evaluation of current economic and business conditions.

        We establish a general allowance on non-classified loans to recognize the inherent losses associated with lending activities, but which, unlike specific allowances, have not been allocated to particular problem loans. This general valuation allowance is determined by segregating the loans by loan category and assigning allowance percentages to each category. An evaluation of each category is made to determine the need to further segregate the loans within each category by type. For our residential mortgage and consumer loan portfolios, we identify similar characteristics throughout the portfolio including credit scores, loan-to-value ratios and collateral. For our commercial real estate and construction loan portfolios, a further analysis is made in which we segregated the loans by type based on the purpose of the loan and the collateral properties securing the loan. Various risk factors for each type of loan are considered, including the impact of general economic and business conditions, collateral value trends, credit quality trends and historical loss experience.

        As of December 31, 2012, DNB had $11.7 million of non-performing assets, which included $10.4 million of non-performing or impaired loans and $1.2 million of OREO. Loans are reviewed for impairment in accordance with FASB ASC 310-10-35. Impaired loans can either be secured or unsecured, not including large groups of smaller balance loans that are collectively evaluated. Impairment is measured by the difference between the loan amount and the present value of the future cash flow discounted at the loan's effective interest rate. Management measures loans for impairment by using the fair value of collateral for collateral dependent loans. In general, management reduces the amount of the appraisal by the estimated cost of acquisition and disposition of the underlying collateral and compares that adjusted value with DNB's carrying value. As part of the general allowance, DNB reserves at the rate of approximately 6% to 10% on non-performing loans. DNB establishes a specific valuation allowance on impaired loans that have a collateral shortfall, including estimated costs to sell in comparison to the carrying value of the loan. Of the $12.3 million of impaired loans at December 31, 2012, $6.9 million had a valuation allowance of $1.0 million and $5.4 million had no specific allowance as of December 31, 2012. For those impaired loans that management determined that no specific valuation allowance was necessary,

management has reviewed the appraisal for each loan and determined that there is no shortfall in the collateral. During the year ended December 31, 2012, we recognized $947,000 in charge-offs related to impaired loans. An impaired loan may not represent an expected loss.

        We typically order new third-party appraisals or collateral valuations when a loan becomes impaired or is transferred to OREO. This is done within two weeks of a loan becoming impaired or a loan moving to OREO. It generally takes two to eight weeks to receive the appraisals, depending on the type of property being appraised. We recognize any provision or related charge-off within two weeks of receiving the appraisal after the appraisal has been reviewed by DNB. We generally order a new appraisal for all impaired real estate loans having a balance of $100,000 or higher, every twelve months, unless management determines more frequent appraisals are necessary. We use updated valuations when time constraints do not permit a full appraisal process, to reflect rapidly changing market conditions. Because appraisals and updated valuations utilize historical data in reaching valuation conclusions, the appraised or updated value may or may not reflect the actual sales price that we will receive at the time of sale. Management uses the qualitative factor "Changes in the value of underlying collateral for collateral-dependent loans" to calculate any required write-down to mitigate this risk.

        Real estate appraisals typically include up to three approaches to value: the sales comparison approach, the income approach (for income-producing property) and the cost approach. Not all appraisals utilize all three approaches to value. Depending on the nature of the collateral and market conditions, the appraiser may emphasize one approach over another in determining the fair value of collateral.

        Appraisals may also contain different estimates of value based on the level of occupancy or future improvements. "As-is" valuations represent an estimate of value based on current market conditions with no changes to the collateral's use or condition. "As-stabilized" or "as-completed" valuations assume that the collateral is improved to a stated standard or achieves its highest and best use in terms of occupancy. "As-stabilized" valuations may be subject to a present value adjustment for market conditions or the schedule for improvements.

        In connection with the valuation process, we will typically develop an exit strategy for the collateral by assessing overall market conditions, the current condition and use of the asset and its highest and best use. For most income- producing real estate, investors value most highly a stable income stream from the asset; consequently, we conduct a comparative evaluation to determine whether conducting a sale on an "as-is" basis or on an "as-stabilized" basis is most likely to produce the highest net realizable value and compare these values with the costs incurred and the holding period necessary to achieve the "as stabilized" value.

        Our estimates of the net realizable value of collateral include a deduction for the expected costs to sell the collateral or such other deductions as deemed appropriate. For most real estate collateral, we apply a seven to ten percent deduction to the value of real estate collateral to determine its expected costs to sell the asset. This estimate generally includes real estate commissions, one year of real estate taxes and miscellaneous repair and closing costs. If we receive a purchase offer that requires unbudgeted repairs, or if the expected holding period for the asset exceeds one year, then we include the additional real estate taxes and repairs or other holding costs in the expected costs to sell the collateral on a case-by-case basis.

5.    Certain Regulatory Matters

        Dividends payable to DNB by the Bank are subject to certain regulatory limitations. Under normal circumstances, the payment of dividends in any year without regulatory permission is limited to the net profits (as defined for regulatory purposes) for that year, plus the retained net profits for the preceding two calendar years. The sum of these items amounted to $11.3 million for the year ended December 31, 2012. During 2012, the Bank paid $720,000 to DNB. During 2013, the Bank will need to provide dividends to DNB in connection with the $13.0 million of Non-Cumulative Perpetual Preferred Stock sold on August 4, 2011 as part of the Small Business Lending Fund program administered by the United States Treasury.

        The FDIC has authority to assess and change federal deposit insurance assessment rates on assessable deposits of the Bank. For further information, please refer to the discussion of FDIC deposit insurance assessments under Part I, Item 1 ("Business"), section (c) ("Narrative Description of Business") — "Supervision and Regulation — Bank" under the heading "Deposit Insurance Assessments" on page 10 of this report. DNB's FDIC insurance expense was $470,000 in 2012.

        DNB was well capitalized at December 31, 2012 and met all regulatory capital requirements. Please refer to Note 16 for a table that summarizes required capital ratios and the corresponding regulatory capital positions of DNB and the Bank at December 31, 2012.

        At December 31, 2012, DNB owned $2.2 million of stock of the Federal Home Loan Bank of Pittsburgh ("FHLBP") and had outstanding borrowings of $20.0 million from the FHLBP. The FHLBP stock entitles DNB to dividends from the FHLBP. DNB recognized dividend income of $4,000 in 2012. At December 31, 2012, DNB's excess borrowing capacity from the FHLBP was $178.2 million. Generally, the loan terms from the FHLBP are better than the terms DNB can receive from other sources.

6.    Off Balance Sheet Arrangements

        In the normal course of business, various commitments and contingent liabilities are outstanding, such as guarantees and commitments to extend credit, borrow money or act in a fiduciary capacity, which are not reflected in the consolidated financial statements. Management does not anticipate any significant losses as a result of these commitments.

        DNB had outstanding stand-by letters of credit totaling $2.1 million and unfunded loan and lines of credit commitments totaling $67.8 million at December 31, 2012.

        These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the balance sheet. The exposure to credit loss, in the event of non-performance by the party to the financial instrument for commitments to extend credit and stand-by letters of credit, is represented by the contractual amount. Management uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.

        Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. DNB evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral, if any, obtained upon the extension of credit, usually consists of real estate, but may include securities, property or other assets.

        Stand-by letters of credit are conditional commitments issued by DNB to guarantee the performance or repayment of a financial obligation of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risks involved in issuing letters of credit are essentially the same as those involved in extending loan facilities to customers. DNB holds various forms of collateral to support these commitments.

Table of Contents

        DNB maintains borrowing arrangements with various correspondent banks, the Federal Home Loan Bank of Pittsburgh and the Federal Reserve Bank of Philadelphia to meet short-term liquidity needs. Through these relationships, DNB has available credit of approximately $195.2 million at December 31, 2012. At December 31, 2012, DNB had borrowed $20.0 million and the FHLBP had issued letters of credit, on DNB's behalf, totaling $20.0 million against its available credit lines.

        As of December 31, 2012, approximately $68.6 million of assets are held by DNB First Wealth Management in a fiduciary, custody or agency capacity. These assets are not assets of DNB, and are not included in the consolidated financial statements.

These payments are not included in the table above.

Item 7A.        Quantitative and Qualitative Disclosures About Market Risk

        To measure the impacts of longer-term asset and liability mismatches beyond two years, DNB utilizes Key Rate Duration and Economic Value of Equity ("EVE") models. The Key Rate Duration measures the differences in durations in various maturity buckets and indicates potential asset and liability mismatches. Because of balance sheet optionality, an EVE analysis is also used to dynamically model the present value of asset and liability cash flows, with rates ranging up or down 200 basis points. The economic value of equity is likely to be different if rates change. Results falling outside prescribed ranges require action by management. At December 31, 2012 and 2011, DNB's variance in the economic value of equity as a percentage of assets with an instantaneous and sustained parallel shift of 200 basis points was within its negative 3% guideline, as shown in the table below. The change as a percentage of the present value of equity with a 200 basis point increase or decrease at December 31, 2012 and 2011was within DNB's negative 25% guideline.

Notes to Consolidated Financial Statements

(1)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        DNB Financial Corporation (the "Corporation" or "DNB") through its wholly owned subsidiary, DNB First, National Association (the "Bank"), formerly Downingtown National Bank, has been serving individuals and small to medium sized businesses of Chester County, Pennsylvania since 1860. DNB Capital Trust I and II are special purpose Delaware business trusts, which are not consolidated (see additional discussion in Junior Subordinated Debentures — Note 9). The Bank is a locally managed commercial bank providing personal and commercial loans and deposit products, in addition to investment and trust services from thirteen community offices. The Bank encounters vigorous competition for market share from commercial banks, thrift institutions, credit unions and other financial intermediaries.

        The consolidated financial statements of DNB and its subsidiary, the Bank, which together are managed as a single operating segment, are prepared in accordance with U.S. generally accepted accounting principles applicable to the banking industry.

        In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the balance sheets, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Amounts subject to significant estimates are items such as the allowance for credit losses and lending related commitments, the fair value of repossessed assets, pension and post-retirement obligations, the fair value of financial instruments and other-than-temporary impairments. Among other effects, such changes could result in future impairments of investment securities, and establishment of allowances for credit losses and lending related commitments as well as increased benefit plans' expenses.

        Principles of Consolidation    The accompanying consolidated financial statements include the accounts of DNB and its wholly owned subsidiary, the Bank. All significant inter-company transactions have been eliminated.

        Cash and Due From Banks    For purposes of the consolidated statement of cash flows, cash and due from banks, and federal funds sold are considered to be cash equivalents. Generally, federal funds are sold for one-day periods.

        Investment Securities    Investment securities are classified and accounted for as follows:

        Held-To-Maturity ("HTM") includes debt securities that DNB has the positive intent and ability to hold to maturity. Debt securities are reported at cost, adjusted for amortization of premiums and accretion of discounts.

        Available-For-Sale ("AFS") includes debt and equity securities not classified as HTM securities. Securities classified as AFS are securities that DNB intends to hold for an indefinite period of time, but not necessarily to maturity. Such securities are reported at fair value, with unrealized holding gains and losses excluded from earnings and reported, net of tax (if applicable), as a separate component of stockholders' equity. Realized gains and losses on the sale of AFS securities are computed on the basis of specific identification of the adjusted cost of each security. Amortization of premiums and accretion of discounts for all types of securities are computed using a method approximating a level-yield basis.

        Other Than Temporary Impairment Analysis Securities are evaluated on a quarterly basis, and more frequently when market conditions warrant such an evaluation, to determine whether declines in their value are other-than-temporary. To determine whether a loss in value is other-than-temporary, management utilizes criteria such as the reasons underlying the decline, the magnitude and duration of the decline, and whether or not management intends to sell or expects that it is more likely than not that it will be required to sell the security prior to an anticipated recovery of the fair value. Once a decline in value for a debt security is determined to be other-than-temporary, the other-than-temporary impairment is

Table of Contents

separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total impairment related to credit losses should be included in earnings. The amount of the total impairment related to all other factors should be included in other comprehensive income. DNB recorded no impairment charges in 2012 or 2011.

        Restricted Stock includes investments in Federal Home Loan Bank of Pittsburgh (FHLBP), Federal Reserve Bank (FRB) and Atlantic Central Bankers Bank (ACBB) stock which are carried at cost and are redeemable at par with certain restrictions. Investments in these stocks are necessary to participate in FHLB, FRB and ACBB programs. Restricted stock represents required investments in the common stock of a correspondent bank and is carried at cost. As of December 31, 2012 and December 31, 2011, restricted stock consists solely of the common stock of the Federal Home Loan Bank of Pittsburgh ("FHLBP"). Management's evaluation and determination of whether these investments are impaired is based on their assessment of the ultimate recoverability of their cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of an investment's cost is influenced by criteria such as (1) the significance of the decline in net assets of the FHLBP as compared to the capital stock amount for the FHLBP and the length of time this situation has persisted, (2) commitments by the FHLBP to make payments required by law or regulation and the level of such payment in relation to the operating performance of the FHLBP, and (3) the impact of legislative and regulatory changes on institutions and, accordingly, on the customer base of the FHLBP. The FHLBP repurchased $288,000 and $577,000 of excess capital stock during 2012 and 2011, respectively. At December 31, 2012, DNB owned $2.2 million of stock of the Federal Home Loan Bank of Pittsburgh ("FHLBP") and had outstanding borrowings of $20.0 million from the FHLBP. The FHLBP stock entitles DNB to dividends from the FHLBP. DNB recognized dividend income of $4,000 in 2012. At December 31, 2012, DNB's excess borrowing capacity from the FHLBP was $178.2 million.

        Loans and Leases    Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for credit losses and any deferred fees or costs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) of the related loans. DNB is generally amortizing these amounts over the contractual life of the loan. Premiums and discounts on purchased loans are amortized as adjustments to interest income using the effective yield method.

        The loans receivable portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following classes: commercial mortgages, commercial term loans, and commercial leases. Consumer loans consist of the following classes: residential mortgages and consumer loans.

        For all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on non-accrual, interest accruals cease and uncollected accrued interest is reversed and charged against current income. Interest received on nonaccrual loans including impaired loans generally is either applied against principal or reported as interest income, according to management's judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The past due status of all classes of loans receivable is determined based on contractual due dates for loan payments.

52

Table of Contents

        Deferred Loan Fees and Costs    Loan origination and commitment fees and related direct-loan origination costs of completed loans are deferred and accreted to income as a yield adjustment over the life of the loan using the level-yield method. The accretion to income is discontinued when a loan is placed on non-accrual status. When a loan is paid off, any unamortized net deferred fee balance is credited to income. When a loan is sold, any unamortized net deferred fee balance is considered in the calculation of gain or loss.

        Allowance for Credit Losses    The allowance for credit losses consists of the allowance for loan losses and represents management's estimate of losses inherent in the loan portfolio as of the balance sheet date and is recorded as a reduction to loans. The allowance for credit losses is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Non-residential consumer loans are generally charged off no later than 120 days past due on a contractual basis, earlier in the event of Bankruptcy, or if there is an amount deemed uncollectible. No portion of the allowance for loan losses is restricted to any individual loan or groups of loans, and the entire allowance is available to absorb any and all loan losses.

        The allowance for credit losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on DNB's past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower's ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available.

        The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not considered impaired, as well as smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure, based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These qualitative risk factors include:

1.

Lending policies and procedures, including underwriting standards and collection, charge-off and recovery practices

2.

National, regional, and local economic and business conditions as well as the condition of various market segments, including the value of underlying collateral for collateral dependent loans

3.

Nature and volume of the portfolio and terms of loans

4.

Experience, ability, and depth of lending management and staff

5.

Volume and severity of past due, classified and nonaccrual loans as well as other loan modifications

6.

Quality of DNB's loan review system, and the degree of oversight by DNB's Board of Directors

7.

Existence and effect of any concentrations of credit and changes in the level of such concentrations

8.

Effect of external factors, such as competition and legal and regulatory requirements

9.

Changes in the value of underlying collateral for collateral-dependent loans

        Each factor is assigned a value to reflect improving, stable or declining conditions based on management's best judgment using relevant information available at the time of the evaluation.

53

Table of Contents

Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for credit loss calculation.

        Commercial real estate lending entails significant additional risks as compared with single-family residential property lending. Such loans typically involve large loan balances to single borrowers or groups of related borrowers. The payment experience on such loans is typically dependent on the successful operation of the real estate project. The success of such projects is sensitive to changes in supply and demand conditions in the market for commercial real estate as well as economic conditions generally.

        Construction lending is generally considered to involve a higher level of risk as compared to single-family residential lending, due to the concentration of principal in a limited number of loans and borrowers and the effects of general economic conditions on developers and builders. Moreover, a construction loan can involve additional risks because of the inherent difficulty in estimating both a property's value at completion of the project and the estimated cost (including interest) of the project. The nature of these loans is such that they are generally more difficult to evaluate and monitor. DNB has attempted to minimize the foregoing risks by, among other things, limiting the extent of its construction lending and has adopted underwriting guidelines which impose stringent loan-to-value, debt service and other requirements for loans which are believed to involve higher elements of credit risk, by limiting the geographic area in which DNB will do business and by working with builders with whom it has established relationships.

        Consumer loans generally have shorter terms and higher interest rates than mortgage loans but generally involve more credit risk than mortgage loans because of the type and nature of the collateral and, in certain cases, the absence of collateral. In addition, consumer lending collections are dependent on the borrower's continuing financial stability, and thus are more likely to be adversely effected by job loss, divorce, illness and personal bankruptcy. In most cases, any repossessed collateral for a defaulted consumer loan will not provide an adequate source of repayment of the outstanding loan balance because of improper repair and maintenance of the underlying security. The remaining deficiency often does not warrant further substantial collection efforts against the borrower. DNB believes that the generally higher yields earned on consumer loans compensate for the increased credit risk associated with such loans and that consumer loans are important to its efforts to provide a full range of services to its customers.

        An unallocated component is maintained to cover uncertainties that could affect management's estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

        A loan is considered impaired when, based on current information and events, it is probable that DNB will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and industrial loans, commercial real estate loans and commercial construction loans by either the present value of expected future cash flows discounted at the loan's effective interest rate or the fair value of the collateral if the loan is collateral dependent.

        An allowance for credit losses is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of DNB's impaired loans are measured based on the estimated fair value of the loan's collateral.

54

---

Table of Contents

        For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property.

        For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower's financial statements, inventory reports, accounts receivable agings or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets.

        Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, DNB does not separately identify individual residential mortgage loans, with the exception of certain purchased residential loans, home equity loans and other consumer loans for impairment disclosures, unless such loans are the subject of a troubled debt restructuring agreement.

        Loans whose terms are modified are classified as troubled debt restructurings if DNB grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve a temporary reduction in interest rate or an extension of a loan's stated maturity date. Non-accrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive months after modification. Loans classified as troubled debt restructurings are designated as impaired.

        The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower's overall financial condition, repayment sources, guarantors and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial and consumer loans. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful and loss. Loans criticized special mention have potential weaknesses that deserve management's close attention. If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. Loans classified substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They include loans that are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified doubtful have all the weaknesses inherent in loans classified substandard with the added characteristic that collection or liquidation in full, on the basis of current conditions and facts, is highly improbable. Loans classified as a loss are considered uncollectible and are charged to the allowance for loan losses. Loans not classified are rated pass.

        In addition, Federal regulatory agencies, as an integral part of their examination process, periodically review DNB's allowance for credit losses and may require DNB to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management's comprehensive analysis of the loan portfolio, management believes the current level of the allowance for credit losses is appropriate.

        Other Real Estate Owned & Other Repossessed Property    Other real estate owned ("OREO") and other repossessed property consists of properties acquired as a result of, or in-lieu-of, foreclosure as well as other repossessed property. Properties classified as OREO are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value or fair value, less estimated costs to sell. Costs relating to the development or improvement of the properties are capitalized and costs relating to holding the properties are charged to expense.

55

---

Table of Contents

        Office Properties and Equipment    Office properties and equipment are recorded at cost. Depreciation is computed using the straight-line method over the expected useful lives of the assets. The costs of maintenance and repairs are expensed as they are incurred; renewals and betterments are capitalized. All long-lived assets are reviewed for impairment, based on the fair value of the asset. In addition, long-lived assets to be disposed of are generally reported at the lower of carrying amount or fair value, less cost to sell. Gains or losses on disposition of properties and equipment are reflected in operations.

        Income Taxes    DNB accounts for income taxes in accordance with the income tax accounting guidance set forth in FASB ASC Topic 740, Income Taxes.

        The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. DNB determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.

        DNB recognizes interest and penalties on income taxes as a component of income tax expense. DNB is no longer subject to examinations by taxing authorities for the years before January 1, 2009.

        Pension Plan    The Bank maintains a noncontributory defined benefit pension plan covering substantially all employees over the age of 21 with one year of service. Plan benefits are based on years of service and the employee's monthly average compensation for the highest five consecutive years of their last ten years of service (see Note 13 — Benefit Plans).

        Stock Based Compensation    Stock compensation accounting guidance (FASB ASC Topic 718, Compensation — Stock Compensation) requires that the compensation cost relating to share-based payment transactions be recognized in financial statements. That cost will be measured based on the grant date fair value of the equity or liability instruments issued. The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans.

        The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees' service period, generally defined as the vesting period. For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. A Black Sholes model is used to estimate the fair value of stock options, while the market price of DNB's common stock at the date of grant is used for restricted stock awards.

        Preferred Stock    Preferred stock ranks senior to common stock with respect to dividends and has preference in the event of liquidation.

        Fixed rate cumulative perpetual preferred stock, Series 2008A — The shares of fixed rate cumulative perpetual preferred stock, Series 2008A ("Series 2008A Preferred Stock") issued to the United States Treasury ("U.S. Treasury") under the TARP Capital Purchase Program ("CPP") of the Emergency Economics Stabilization Act of 2008 and the warrants issued under the CPP were accounted for as permanent equity on the Consolidated Statements of Financial Condition. The proceeds received were allocated between the Series 2008A Preferred Stock and the warrants based upon their relative fair values as of the date of issuance which resulted in the recording of a discount of the Series 2008A Preferred Stock upon issuance that reflects the value allocated to the warrants. The discount was accreted by a charge to retained earnings on a straight-line basis over the expected life of the preferred stock of five years and then in full when the CPP preferred stock was redeemed in 2011. DNB paid cumulative dividends at a rate of five percent per annum while these shares were outstanding. Dividends were payable quarterly in arrears and accrued as earned over the period the Series 2008A Preferred Stock was outstanding. Preferred dividends paid (declared and accrued) and the related accretion was deducted from net income for computing income available to common stockholders and earnings per share computations.

        Non-Cumulative Perpetual Preferred Stock, Series 2011A — The shares of Non-Cumulative Perpetual Preferred Stock, Series 2011A ("Series 2011A Preferred Stock") issued to the United States Treasury ("U.S. Treasury") under the Small Business Lending Fund program ("SBLF") are accounted for as permanent equity on DNB's Consolidated Statements of Financial Condition. Proceeds received from the issuance of the SBLF preferred stock were used to redeem the CPP preferred stock.

        The Series 2011A Preferred Stock is entitled to receive non-cumulative dividends payable quarterly. The dividend rate, which is calculated on the aggregate Liquidation Amount, was initially set at 3.874% per annum based upon the current level of "Qualified Small Business Lending", or "QSBL" (as defined in the Securities Purchase Agreement) by DNB's wholly owned subsidiary, DNB First, National Association (the "Bank"). The dividend rate for future dividend periods will be set based upon the "Percentage Change in Qualified Lending" (as defined in the Securities Purchase Agreement) between each dividend period and the "Baseline" QSBL level. Such dividend rate may vary from 1% per annum to 5% per annum for the second through tenth dividend periods depending on the volume of QSBL the Bank originates in future periods, and will be fixed at a rate between 1% per annum to 7% per annum and remain unchanged up to four and one-half years following the funding date (the eleventh through the first half of the nineteenth dividend periods). If the Series 2011A Preferred Stock remains outstanding for more than four-and-one-half years, the dividend rate will be fixed at 9%. Prior to that time, in general, the dividend rate decreases as the level of the Bank's QSBL increases. At December 31, 2012 the dividend rate was 1.00%. Such dividends are not cumulative, but DNB may only declare and pay dividends on its common stock (or any other equity securities junior to the Series 2011A Preferred Stock) if it has declared and paid dividends for the current dividend period on the Series 2011A Preferred Stock, and will be subject to other restrictions on its ability to repurchase or redeem common stock and other securities. In addition, if (i) DNB has not timely declared and paid dividends on the Series 2011A Preferred Stock for six dividend periods or more, whether or not consecutive, and (ii) shares of Series 2011A Preferred Stock with an aggregate liquidation preference of at least $13,000,000 are still outstanding, the Treasury (or any successor holder of Series 2011A Preferred Stock) may designate two additional directors to be elected to DNB's Board of Directors. Preferred dividends paid (declared and accrued) is deducted from net income for computing income available to common stockholders and earnings per share computations.

        Earnings Per Common Share (EPS)    Basic EPS is computed based on the weighted average number of common shares outstanding during the year. Diluted EPS reflects the potential dilution that could occur from unvested stock awards and the exercise of stock options and warrants computed using the treasury stock method. Stock options and awards for which the exercise price exceeds the average market price over the period have an anti-dilutive effect on EPS and, accordingly, are excluded from the EPS calculation. Treasury shares are not deemed outstanding for earnings per share calculations.

        Comprehensive Income    Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains on securities available for sale, accretion

of discount on securities transferred from available-for-sale to held-to-maturity, and changes in the funded status of the pension plan which are also recognized as separate components of stockholders' equity.

(2)    INVESTMENT SECURITIES

        The amortized cost and estimated fair values of investment securities, as of the dates indicated, are summarized as follows:

---

Table of Contents

        Included in unrealized losses are market losses on securities that have been in a continuous unrealized loss position for twelve months or more and those securities that have been in a continuous unrealized loss position for less than twelve months. The table below details the aggregate unrealized losses and aggregate fair value of the underlying securities whose fair values are below their amortized cost at December 31, 2012 and 2011.

 

        As of December 31, 2012, there were 3 certificates of deposit, 14 municipalities, 13 corporate bonds, 5 agency notes, 3 collateralized mortgage obligations and 6 equity securities which were in an unrealized loss position. Thirty-five of these 44 securities did not meet the criteria of having market value loss greater than 10% of book value or having been in a loss position for more than 12 months. DNB does not intend to sell these securities and management of DNB does not expect to be required to sell any of these securities prior to a recovery of its cost basis. Management does not believe any individual unrealized loss as of December 31, 2012 represents an other-than-temporary impairment. There were 3 corporate bonds and 6 equity securities that were impaired for more than 12 months. DNB reviews its investment portfolio on a quarterly basis judging each investment for other-than-temporary impairment (OTTI). The OTTI analysis focuses on duration and amount a security is below book. As of December 31, 2012, the following securities were reviewed:

        Corporates    The unrealized loss on three investments in the Corporate Bond portfolio were caused by interest rate increases and increased spreads in this sector. Some of the bonds have had downgrades since they were purchased. The book value of the three securities is $3.5 million and the unrealized loss is

60

---

Table of Contents

$115,000. The three corporate bonds have been impaired for more than twelve months and had a loss less than 10% of the book value. The contractual terms of those investments do not permit the issuer to settle these securities at a price less than the amortized cost basis of the investments. Based on this analysis and an evaluation of DNB's ability and intent to hold these investments for a reasonable period of time sufficient for each security to increase to DNB's cost, DNB does not intend to sell these investments and it is not more likely than not that DNB will be required to sell the investments before recovery of their cost, DNB does not consider these investments to be other-than-temporarily impaired at December 31, 2012.

        Equity securities    DNB's investment in six marketable equity securities consist primarily of investments in common stock of community banks in Pennsylvania. The unrealized losses on the six investments in the Equity securities portfolio were all impaired for more than twelve months. The severity and duration of the impairment are driven by higher collateral losses, wider credit spreads, and changes in interest rates within the financial services sector. DNB evaluated the prospects of all issuers in relation to the severity and duration of the impairment. Based on this analysis and an evaluation of DNB's ability and intent to hold these investments for a reasonable period of time sufficient for each security to increase to DNB's cost, DNB does not intend to sell these investments and it is not more likely than not that DNB will be required to sell the investments before recovery of their cost, DNB does not consider these investments to be other-than-temporarily impaired at December 31, 2012.

        The amortized cost and estimated fair value of investment securities as of December 31, 2012, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because certain securities may be called or prepaid without penalties.

        DNB sold $19.7 million and $27.8 million securities from the AFS portfolio during 2012 and 2011, respectively. Gains and losses resulting from investment sales, redemptions or calls were as follows:

        At December 31, 2012 and 2011, investment securities with a carrying value of approximately $90 million and $96 million, respectively, were pledged to secure public funds, repurchase agreements, FHLBP advances and for other purposes as required by law. See Note 7 regarding the use of certain securities as collateral.

        Certificates of deposit scheduled to mature have the following remaining maturities:

(7)    FHLBP ADVANCES AND SHORT-TERM BORROWED FUNDS

        DNB's short-term borrowed funds consist of borrowings at the Federal Home Loan Bank of Pittsburgh (FHLBP), repurchase agreements and Federal funds purchased. Repurchase agreements and Federal funds purchased generally represent one-day borrowings. Borrowings at the FHLBP consist of overnight and 90 day borrowings. DNB had $17.0 million of repurchase agreements at December 31, 2012 with an average rate of 0.30% and $23.8 million of repurchase agreements at December 31, 2011 with an average rate of 0.40%.

        In addition to short-term borrowings, DNB maintains borrowing arrangements with a correspondent bank and the FHLBP, as well as access to the discount window at the Federal Reserve Bank of Philadelphia to meet short-term liquidity needs. Through these relationships, DNB has available credit of approximately $195.2 million. DNB has a maximum borrowing capacity at the FHLBP of approximately $178.2 million. At December 31, 2012, DNB had $20.0 million of outstanding long-term advances, which mature at various dates through the year-ended December 31, 2015, as shown in the table below. These advances are collateralized by loans and investment securities, and a lien on the Bank's FHLBP stock. At December 31, 2011, DNB had $20.0 million of outstanding long-term advances with an average rate of 4.17%. All of the advances are convertible term advances and are callable, at the FHLBP's option, at various dates. If an advance is called by the FHLBP, DNB has the option of repaying the borrowing, or continuing to borrow at three month Libor plus 10-14 basis points, depending on the advance. In addition to the $20.0 million of borrowings from the FHLBP at December 31, 2012, the FHLBP had issued letters of credit, on DNB's behalf, totaling $20.0 million against DNB's available credit lines. These letters of credit were used to secure public deposits as required by law.

As of December 31, 2012 the lease has a carrying amount of $309,000 net of accumulated depreciation of $441,000, and is included in the balance of office properties and equipment in the accompanying statements of financial condition. The following is a schedule of the future minimum capital lease payments, together with the present value of the net minimum lease payments, as of December 31, 2012:

        The following is a schedule of the future minimum operating lease payments as of December 31, 2012.

(9)    JUNIOR SUBORDINATED DEBENTURES

        DNB has two issuances of junior subordinated debentures (the "debentures") as follows. The majority of the proceeds of each issuance were invested in DNB's subsidiary, DNB First, National Association, to increase the Bank's capital levels. The junior subordinated debentures issued in each case qualify as a component of capital for regulatory purposes. DNB Capital Trust I and II are special purpose Delaware business trusts, which are not consolidated.

DNB Capital Trust I

        DNB's first issuance of junior subordinated debentures was on July 20, 2001. This issuance of debentures are floating rate and were issued to DNB Capital Trust I, a Delaware business trust in which DNB owns all of the common equity. DNB Capital Trust I issued $5 million of floating rate (6 month Libor plus 3.75%, with a cap of 12%) capital preferred securities to a qualified institutional buyer. The proceeds of these securities were used by the Trust, along with DNB's capital contribution, to purchase $5,155,000 principal amount of DNB's floating rate junior subordinated debentures. The preferred securities have

Table of Contents

been redeemable since July 25, 2006 and must be redeemed upon maturity of the debentures on July 25, 2031.

DNB Capital Trust II

        DNB's second issuance of junior subordinated debentures was on March 30, 2005. This issuance of debentures are floating rate and were issued to DNB Capital Trust II, a Delaware business trust in which DNB owns all of the common equity. DNB Capital Trust II issued $4.0 million of floating rate (the rate was fixed at 6.56% for the first 5 years and is now adjusting at a rate of 3-month LIBOR plus 1.77%) capital preferred securities. The proceeds of these securities were used by the Trust, along with DNB's capital contribution, to purchase $4,124,000 principal amount of DNB's floating rate junior subordinated debentures. The preferred securities have been redeemable since May 23, 2010. The preferred securities must be redeemed upon maturity of the debentures on May 23, 2035.

(10)    FAIR VALUE OF FINANCIAL INSTRUMENTS

        FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy based on the nature of data inputs for fair value determinations, under which DNB is required to value each asset within its scope using assumptions that market participations would utilize to value that asset. When DNB uses its own assumptions, it is required to disclose additional information about the assumptions used and the effect of the measurement on earnings or the net change in assets for the period.

        The three levels of the fair value hierarchy under FASB ASC Topic 820 are as follows:

        Level 1—Quoted prices in active markets for identical securities.

        Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active and model derived valuations whose inputs are observable or whose significant value drivers are observable.

        Level 3—Instruments whose significant value drivers are unobservable.

        A description of the valuation methodologies used for assets measured at fair value is set forth below:

        DNB's available-for-sale investment securities, which generally include U.S. government agencies and mortgage backed securities, collateralized mortgage obligations, corporate bonds and equity securities are reported at fair value. These securities are valued by an independent third party ("preparer"). The preparer's evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

        U.S. Government agencies are evaluated and priced using multi-dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other investments are evaluated using a broker-quote based application, including quotes from issuers.

        Impaired loans are those loans that the Bank has measured impairment generally based on the fair value of the loan's collateral. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are

70

---

Table of Contents

included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

        OREO assets are adjusted to fair value less estimated selling costs upon transfer of the loans to OREO. Subsequently, OREO assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management's estimation of the value of the collateral. There assets are included as level 3 fair values.

        The following table summarizes the assets at December 31, 2012 and December 31, 2011 that are recognized on DNB's balance sheet using fair value measurement determined based on the differing levels of input.

        The following table presents additional information about assets measured at fair value on a nonrecurring basis and for which DNB has utilized Level 3 inputs to determine fair value:

Quantitative Information about Level 3 Fair Value Measurement

 

        Impaired loans.    Impaired loans, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a carrying amount of $12.3 million at December 31, 2012. Of this, $6.9 million had a valuation allowance of $1.0 million and $5.4 million had no valuation allowance as of December 31, 2012. Impaired loans had a carrying amount of $7.6 million at December 31, 2011. Of this, $4.8 million had a valuation allowance of $1.2 million and $2.8 million had no valuation allowance as of December 31, 2011.

        Other Real Estate Owned & other repossessed property.    Other real estate owned ("OREO") consists of properties acquired as a result of, or in-lieu-of, foreclosure. Properties or other assets are classified as OREO and other repossessed property are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value or fair value, less estimated costs to sell. Costs relating to the development or improvement of the assets are capitalized and costs relating to holding the assets are charged to expense. DNB had $1.2 million of such assets at December 31, 2012, which consisted of $1.1 million in OREO and $126,000 in other repossessed property. DNB had $4.0 million of such assets at December 31, 2011, which consisted of $3.8 million in OREO and $212,000 in other repossessed property. Subsequent to the repossession of these assets, DNB wrote down the carrying values by $440,000 in other repossessed assets during the year ending December 31, 2012 and $23,000 during the year ending December 31, 2011.

        Below is management's estimate of the fair value of all financial instruments, whether carried at cost or fair value on DNB's consolidated balance sheet. The carrying amounts and estimated fair values of financial instruments at December 31, 2012 and December 31, 2011 are as follows:

 

73

---

Table of Contents

        The specific estimation methods and assumptions used can have a substantial impact on the resulting fair values of financial instruments. Following is a brief summary of the significant assumptions, methods, and estimates used in estimating fair value.

        Limitations    Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time DNB's entire holdings of a particular financial instrument. Because no market exists for a significant portion of DNB's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

        Cash and Cash Equivalents, Investment Securities, Accrued Interest Receivable and Accrued Interest Payable     The carrying amounts for short-term investments (cash and cash equivalents) and accrued interest receivable and payable approximate fair value. The fair value of investment securities are determined by an independent third party ("preparer"). The preparer's evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

        U.S. Government agencies are evaluated and priced using multi-dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other investments are evaluated using a broker- quote based application, including quotes from issuers. The carrying amount of non-readily marketable equity securities approximates liquidation value.

        Loans    Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, commercial mortgages, residential mortgages, consumer and non-accrual loans. The fair value of performing loans is calculated by discounting expected cash flows using an estimated market discount rate. Expected cash flows include both contractual cash flows and prepayments of loan balances. Prepayments on consumer loans were determined using the median of estimates of securities dealers for mortgage-backed investment pools.

        The estimated discount rate considers credit and interest rate risk inherent in the loan portfolios and other factors such as liquidity premiums and incremental servicing costs to an investor. Management has made estimates of fair value discount rates that it believes to be reasonable. However, because there is no market for many of these financial instruments, management has no basis to determine whether the fair value presented would be indicative of the value negotiated in an actual sale.

        The fair value for non-accrual loans not based on fair value of collateral was derived through a discounted cash flow analysis, which includes the opportunity costs of carrying a non-performing asset. An estimated discount rate was used for these non-accrual loans, based on the probability of loss and the expected time to recovery.

        Deposits and Borrowings    The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of

74

---

Table of Contents

variable-rate money market accounts, savings accounts, and interest checking accounts approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

        Off-balance-sheet Instruments (Disclosed at Cost)    Off-balance- sheet instruments are primarily comprised of loan commitments, which are generally priced at market at the time of funding. Fees on commitments to extend credit and stand-by letters of credit are deemed to be immaterial and these instruments are expected to be settled at face value or expire unused. It is impractical to assign any fair value to these instruments. At December 31, 2012, un-funded loan commitments totaled $67.8 million. Stand-by letters of credit totaled $2.1 million at December 31, 2012. At December 31, 2011, un-funded loan commitments totaled $57.7 million. Stand-by letters of credit totaled $4.0 million at December 31, 2011.

(11)    FEDERAL INCOME TAXES

        Income tax expense (benefit) was comprised of the following:

        The effective income tax rates of 28.7% for 2012 and 29.6% for 2011 were different than the applicable statutory Federal income tax rate of 34%. The reason for these differences follows:

Table of Contents

        The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are presented below:

        As of December 31, 2012, DNB had no material unrecognized tax benefits or accrued interest and penalties. It is DNB's policy to account for interest and penalties accrued relative to unrecognized tax benefits as a component of income tax expense. Federal and state tax years 2009 through 2012 were open for examination as of December 31, 2012.

        DNB had net operating loss carryovers with the Commonwealth of Pennsylvania of $6.0 million and $5.7 million at December 31, 2012 and 2011, respectively for which a full valuation allowance has been established. These carryovers will begin to expire in 2021.

(12)    EARNINGS PER COMMON SHARE

        Basic earnings per share ("EPS") is computed based on the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the treasury stock method and reflects the potential dilution that could occur from the exercise of stock options, and warrants and the amortized portion of unvested stock awards. Stock options and unvested stock awards for which the exercise or the grant price exceeds the average market price over the period have an anti-dilutive effect on EPS and, accordingly, are excluded from the calculation. Treasury shares are not deemed outstanding for calculations. There were 128,568 anti-dilutive stock options outstanding, and no anti-dilutive stock awards at December 31, 2012. There were 148,459 anti-dilutive stock options outstanding, and no anti-dilutive stock awards at December 31, 2011. The following table sets forth the computation of basic and diluted earnings per share:

(13)    BENEFIT PLANS

        Pension Plan    The Bank maintains a defined benefit pension plan (the "Plan") covering all employees, including officers, who have been employed for one year and have attained 21 years of age. Prior to May 1, 1985, an individual must have attained the age of 25 and accrued one year of service. The Plan provides pension benefits to eligible retired employees at 65 years of age equal to 1.5% of their average monthly pay multiplied by their years of accredited service (maximum 40 years). The accrued benefit is based on the monthly average of their highest five consecutive years of their last ten years of service. The Plan generally covers only full-time employees.

        Effective December 31, 2003, DNB amended its Plan to curtail future eligibility and so that no participants will earn additional benefits under the Plan after December 31, 2003. As a result of this amendment, no further service or compensation was credited under the Plan after December 31, 2003. The Plan, although frozen, will continue to provide benefit payments and employees can still earn vesting credits until retirement.

As of December 31, 2012, the plan held 77.98% of its assets in bonds and cash due to market volatility surrounding fiscal cliff negotiations.

        Retirement and Death Benefit Agreement    During 1999, the Bank and Henry F. Thorne, its then current Chief Executive Officer (the "Executive"), entered into a Death Benefit Agreement providing for supplemental death and retirement benefits for him (the "Supplemental Plan"). In 2003, the Supplemental Plan was replaced by a Retirement and Death Benefit Agreement (the "Replacement Plan").

        The Replacement Plan provides that the Bank and the Executive share in the rights to the cash surrender value and death benefits of a split-dollar life insurance policy (the "Policy") The policy is designed to provide the Executive, upon attaining age 65, with projected annual after-tax payments of approximately $35,000. In addition, the Policy is intended to provide the Executive with a projected death benefit of $750,000.

        In July 2008, DNB commenced making monthly payments of $3,658 to the Executive. The remaining liability under the plan was $729,000 and $730,000 as of December 31, 2012 and 2011, respectively. The annual expense for the same respective periods was $51,000 and $41,000.

        Supplemental Executive Retirement Plan for Chairman and Chief Executive Officer    On December 20, 2006, the Board of Directors of DNB Financial Corporation approved, and effective April 1, 2007 and December 8, 2008 modified, a Supplemental Executive Retirement Plan (also known as a SERP) for its Chairman and Chief Executive Officer, William S. Latoff. The purpose of the SERP is to provide Mr. Latoff a pension supplement beginning at age 70 for 15 years in approximately equal amounts each year and to compensate him for the loss of retirement plan funding opportunities from his other business interests because of his commitments to DNB as Chairman and CEO.

        The remaining liability under the plan was $1.2 million and $1.1 million as of December 31, 2012 and 2011, respectively. The annual expense for the same respective periods was $67,000 and $63,000.

        401(k) Retirement Savings Plan    In 1994, the Bank adopted a retirement savings plan intended to comply with Section 401(k) of the Internal Revenue Code of 1986. Participants are permitted to authorize pre-tax savings contributions to a separate trust established under the 401(k) plan, subject to limitations on deductibility of contributions imposed by the Internal Revenue Code. Effective July 1, 2007 the Bank amended the plan to allow after-tax contributions to be made as well. The contributions are subject to the same limitations. Effective January 1, 2010, management indicated that it would evaluate discretionary matching contributions each quarter based upon DNB's financial performance. DNB made no matching contributions to the 401(k) plan in 2012 and 2011.

        Profit Sharing Plan    The Bank maintains a Profit Sharing Plan for eligible employees. The plan provides that the Bank make contributions equal to 3% of the eligible participant's W-2 wages. DNB's

related expense associated with the Profit Sharing Plan was $225,000 and $219,000 in 2012 and 2011, respectively.

        Stock Option Plan    DNB has a Stock Option Plan for employees and directors. Under the plan, options (both qualified and non-qualified) to purchase a maximum of 793,368 (as adjusted for subsequent stock dividends) shares of DNB's common stock could be issued to employees and directors.

        Under the plan, option exercise prices must equal the fair market value of the shares on the date of option grant and the option exercise period may not exceed ten years. Vesting of options under the plan is determined by the Plan Committee. There were 327,964 and 156,144 shares available for grant at December 31, 2012 and 2011, respectively. All options with the exception of 44,600 options granted on April 23, 2010 and 44,600 options granted on December 12, 2011 are immediately exercisable. The options granted on April 23, 2010 have a fair value of $100,000 or $2.25 per share, based on a risk free interest rate of 3.273%, a dividend yield of 1.73% and a volatility of 35.564% and are subject to four year cliff vesting. These options which expire on April 23, 2017 if not exercised or cancelled, have an exercise price of $6.93 per share, and the shares are restricted from resale for two years after exercise. These options are exercisable only at and after such time as the market value of the common stock first equals or exceeds $7.97, which is 115% of the $6.93 exercise price. The options granted on December 12, 2011 have a fair value of $141,000 or $3.17 per share, based on a risk free interest rate of 1.445%, a dividend yield of 1.16% and a volatility of 36.513% and are subject to three year cliff vesting. These options which expire on December 12, 2018 if not exercised or cancelled, have an exercise price of $10.31 per share, and the shares are restricted from resale for two years after exercise. These options are exercisable only at and after such time as the market value of the common stock first equals or exceeds $11.34, which is 110% of the $10.31 exercise price. DNB expensed $69,000 and $27,000 during the years ended December 31, 2012 and 2011, respectively, and anticipates additional expense of $31,000 through April 23, 2014 for the options granted on April 23, 2010 and $91,000 through December 12, 2014 for the options granted on December 12, 2011, the dates the options can first be exercised.

        Other Stock-Based Compensation    DNB maintains an Incentive Equity and Deferred Compensation Plan. The plan provides that up to 243,101 shares of common stock may be granted, at the discretion of the Board, to individuals of DNB. Shares already granted are issuable on the earlier of three years after the date of the grant or a change in control of DNB if the recipients are then employed by DNB ("Vest Date"). Upon issuance of the shares, resale of the shares is restricted for an additional one year, during which the shares may not be sold, pledged or otherwise disposed of. Prior to the Vest Date and in the event the recipient terminates association with DNB for reasons other than death, disability or change in control, the recipient forfeits all rights to the shares that would otherwise be issued under the grant.

        Share awards granted by the plan were recorded at the date of award based on the market value of shares. Awards are being amortized to expense over the three-year cliff-vesting period. DNB records compensation expense equal to the value of the shares being amortized. For the twelve-month periods ended December 31, 2012 and 2011, $74,000 and $61,000 was amortized to expense. At December 31, 2012, approximately $418,000 in additional compensation will be recognized over the weighted average

remaining service period of approximately 1.97 years. At December 31, 2012, 158,354 shares were reserved for future grants under the plan. Stock grant activity is indicated below.

(14)    COMMITMENTS, CONTINGENT LIABILITIES AND OFF-BALANCE-SHEET RISK

        In the normal course of business, various commitments and contingent liabilities are outstanding, such as guarantees and commitments to extend credit, borrow money or act in a fiduciary capacity, which are not reflected in the consolidated financial statements. Management does not anticipate any significant losses as a result of these commitments.

        DNB had outstanding stand-by letters of credit totaling $2.1 million and unfunded loan and lines of credit commitments totaling $67.8 million at December 31, 2012, of which, $60.2 million were variable rate and $7.4 million were fixed rate.

        These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the balance sheet. The exposure to credit loss in the event of non-performance by the party to the financial instrument for commitments to extend credit and stand-by letters of credit is represented by the contractual amount. Management uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.

        Stand-by letters of credit are conditional commitments issued by DNB to guarantee the performance or repayment of a financial obligation of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risks involved in issuing letters of credit are essentially the same as those involved in extending loan facilities to customers. DNB holds various forms of collateral to support these commitments.

        Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. DNB evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral, if any, obtained upon the extension of credit, usually consists of real estate, but may include securities, property or other assets.

        DNB maintains borrowing arrangements with correspondent banks and the FHLB of Pittsburgh, as well as access to the discount window at the Federal Reserve Bank of Philadelphia to meet short-term liquidity needs. Through these relationships, DNB has available credit of approximately $195.2 million.

        Approximately $68.6 million of assets were held by DNB First Wealth Management in a fiduciary, custody or agency capacity at December 31, 2012. These assets are not assets of DNB, and are not included in the consolidated financial statements.

        DNB is a party to a number of lawsuits arising in the ordinary course of business. While any litigation causes an element of uncertainty, management is of the opinion that the liability, if any, resulting from the actions, will not have a material effect on the accompanying financial statements.

(16)    REGULATORY MATTERS

        Under the Federal Reserve's Regulation H, DNB First, National Association may not, without regulatory approval, declare or pay a dividend to DNB if the total of all dividends declared in a calendar year exceeds the total of (a) the Bank's net income for that year and (b) its retained net income for the preceding two calendar years, less any required transfers to additional paid-in capital or to a fund for the retirement of preferred stock.

        Federal banking agencies impose three minimum capital requirements — Total risk-based, Tier 1 risk-based and Leverage capital. The risk-based capital ratios measure the adequacy of a bank's capital against the riskiness of its assets and off-balance sheet activities. Failure to maintain adequate capital is a

basis for "prompt corrective action" or other regulatory enforcement action. In assessing a bank's capital adequacy, regulators also consider other factors such as interest rate risk exposure; liquidity, funding and market risks; quality and level of earnings; concentrations of credit, quality of loans and investments; risks of any nontraditional activities; effectiveness of bank policies; and management's overall ability to monitor and control risks.

        Quantitative measures established by regulation to ensure capital adequacy require DNB to maintain certain minimum amounts and ratios as set forth below. Management believes that DNB and the Bank meet all capital adequacy requirements to which they are subject. The Bank is considered "Well Capitalized" under the regulatory framework for prompt corrective action. To be categorized as Well Capitalized, the Bank must maintain minimum ratios as set forth below. There are no conditions or events since the most recent regulatory notification that management believes would have changed the Bank's category. Actual capital amounts and ratios are presented in the following table.

(17)    BRANCH PURCHASE

        On April 2, 2012, the Bank entered into a Purchase and Assumption Agreement with Capital Bank, National Association, to acquire certain assets and assume certain liabilities of one full-service branch office of Capital Bank located in Boothwyn, Pennsylvania (the "Branch Acquisition").

        The Bank consummated the Branch Acquisition on June 11, 2012. The Bank purchased specified assets of the branch, including personal loans totaling $66,000, real estate, furniture and equipment totaling $670,000 and assumed approximately $15.9 million of deposits. The Branch Acquisition includes the payment to Capital Bank of $130,000 or a 0.82% premium on the deposits, which has been recorded as a core deposit intangible.

Report of Independent Registered Public Accounting Firm

Board of Directors and
Stockholders of DNB Financial Corporation

        We have audited the accompanying consolidated statements of financial condition of DNB Financial Corporation and subsidiaries (the "Corporation") as of December 31, 2012 and 2011, and the related consolidated statements of income, comprehensive income, stockholders' equity and cash flows for the years then ended. These consolidated financial statements are the responsibility of the Corporation's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Corporation is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Corporation's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of DNB Financial Corporation and subsidiaries as of December 31, 2012 and 2011, and the results of their operations and their cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Management's Report on Internal Control Over Financial Reporting

        Management is responsible for establishing and maintaining adequate internal control over financial reporting. Management assessed the effectiveness of DNB's internal control over financial reporting at December 31, 2012. To make this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework. Management believes that, as of December 31, 2012 DNB's internal control over financial reporting was effective. This annual report on Form 10-K does not include an attestation report of DNB's independent registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by DNB's independent registered public accounting firm pursuant to the exemption provided to issuers that are not "large accelerated filers" or "accelerated filers".

        There have been no changes in internal controls over financial reporting that occurred during our fourth quarter of 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
