Lumentum Holdings Inc. (“Lumentum” or the “Company”) today reported results for its fiscal first quarter ended September 26, 2026.

“Lumentum built on its strong momentum in the first fiscal quarter of 2027, delivering growth across all our businesses, with pump lasers and optical circuit switches (OCS) being the leading contributors. During the quarter, we secured our second major NPO/CPO win, backed by purchase commitments exceeding $5 billion. Additionally, our OCS demand visibility has expanded significantly in recent months, positioning optical switching to become a multi-billion-dollar annual revenue stream. Finally, we continue to see strength in our cloud modules business which is showing improvement on the gross margin line,” said President and CEO Michael Hurlston.

"Looking ahead, we anticipate adding approximately $350 million in sequential growth in our second quarter, a figure greater than the quarterly revenue of the whole company just two years ago. Furthermore, we project our second quarter operating margin to exceed 45 percent.”

The tables above provide comparisons of quarterly results to prior periods, including sequential quarterly and year-over-year changes. A reconciliation between GAAP and non-GAAP measures is contained in this release under the section titled “Use of Non-GAAP Financial Measures.”

Business Outlook

Lumentum expects the following for the second quarter of fiscal year 2027:

• Net revenue in the range of $1.575 billion to $1.625 billion
• Non-GAAP operating margin of 45.0% to 46.0%
• Non-GAAP diluted earnings per share of $5.90 to $6.20

We have not provided reconciliations from GAAP to non-GAAP financial measures or the equivalent GAAP measure for non-GAAP financial measures in our outlook, as they cannot be provided without unreasonable effort. A large portion of non-GAAP adjustments, such as stock-based compensation and related payroll taxes, acquisition related costs, net, integration related costs, restructuring and related charges, foreign exchange losses (gains), net, non-GAAP income tax reconciling adjustments, and other non-GAAP adjustments are by their nature highly volatile and we have low visibility as to the range that may be incurred in the future.

The following financial tables are presented in accordance with GAAP, unless otherwise specified.

Use of Non-GAAP Financial Measures

In this press release, Lumentum provides investors with certain non-GAAP financial measures: gross profit, gross margin, research and development expense, selling, general and administrative expense, operating margin, income from operations, total other income (expense), net, income before income taxes, provision for income taxes, net income, shares used in per share calculation, and net income (loss) per share on a non-GAAP basis, as well as the non-GAAP measures of EBITDA and Adjusted EBITDA. Lumentum believes this non-GAAP financial information provides additional insight into the Company’s on-going business operations and results, and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of the Company’s on-going operations and enable more meaningful period to period comparisons. In addition, the Company believes that providing certain of these measures allows investors to better understand the Company’s operating performance and, importantly, to evaluate the methodology and information used by management to monitor, manage, evaluate and measure the Company’s business and results of operations. However, investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future. Moreover, the non-GAAP financial measures we present may be different from non-GAAP financial measures used by other companies or may not be comparable to similarly titled measurements reported by other companies, limiting their usefulness for comparison purposes. We do not consider non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial measures, and the non-GAAP financial measures used in this press release should not be considered in isolation from measures of financial performance prepared in accordance with GAAP.

Our non-GAAP measures used in this press release exclude (i) stock-based compensation and related payroll taxes, (ii) acquisition related costs, net (iii) integration related costs (income), net, (iv) amortization of acquired intangibles, (v) restructuring and related charges, (vi) intangible assets write-off, (vii) gain on sale of business, net (viii) foreign exchange losses (gains), net, (ix) loss on debt extinguishment, (x) inducement expense, (xi) non-cash interest expense, (xii) other charges or income related to non-recurring activities, and (xiii) non-GAAP income tax reconciling adjustments.

We utilize a long-term projected non-GAAP tax rate to compute our non-GAAP income tax provision. The long-term projected non-GAAP tax rate is based on a multi-year projection of our estimated annual GAAP income tax forecast, adjusted to account for the tax effect of non-GAAP pretax adjustments as well as the effects of significant non-recurring and period specific tax items. Our non-GAAP tax provision for fiscal year 2027 is based on a rate of 16.5%. The difference between our GAAP income tax provision and our non-GAAP income tax provision is presented as non-GAAP income tax reconciling adjustments.

A quantitative reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial table attached to this press release.

We calculate basic net income per share pursuant to the two-class method as a result of the issuance of the Series A Convertible Preferred Stock (the “Preferred Stock”) in March 2026. Our Preferred Stock represents a second class of common stock for purposes of computing net income per share under the two-class method as it is entitled to receive dividends on an as-converted basis in the same manner as holders of common stock and does not have any material preferential rights relative to our common stock.

As the Preferred Stock participates on an if-converted basis, and there are no dividends, the income allocated to the two classes of stock converge and the results are mathematically equal. Thus, basic and diluted net income per share is calculated assuming the Preferred Stock have been converted into common stock, and the related shares are included in the weighted average shares outstanding.
