                      Corning Reports Third-Quarter Results

CORNING, N.Y. -- Corning Incorporated (NYSE: GLW) today announced  third-quarter
sales of $1.006  billion,  and that it incurred a net loss of $2.491  billion or
$1.78 per share.  This net loss includes a number of noncash  special items that
reduced Corning's results by $2.704 billion or $1.92 per share in the quarter.

"Our  third-quarter  results reflect  Corning's highest level of sales since the
fourth  quarter  of 2001,"  James R.  Houghton,  chairman  and  chief  executive
officer, said. "We are disappointed with the magnitude of the noncash accounting
charges  we  took  in the  quarter,  but we  continue  to be  pleased  with  our
sequential revenue  improvement and our strong gross margin. We believe that our
business  strategy is working,  and we are well on track to meet our performance
objectives for the year," he said.

Corning's  third-quarter  net income was reduced by $2.704  billion or $1.92 per
share as a result of the following:

.    Restructuring,  impairment  and other charges and credits of $1.794 billion
     ($1.798 billion after-tax and minority  interest)  primarily related to the
     previously  announced  impairment  of  goodwill  and  fixed  assets  in the
     Telecommunications segment.
.    A $50 million  gain to reflect the  decrease in the market value of Corning
     common stock to be contributed to settle the asbestos litigation related to
     Pittsburgh Corning Corporation.
.    A $4 million charge related to Corning's ongoing debt reduction program.
.    A $937 million  increase in the company's income tax expense as a result of
     the  company's   previously-announced   decision  to  provide  a  valuation
     allowance against a significant portion of its deferred tax assets.
.    A previously-announced  $35 million impairment of equity method investments
     in  the  Telecommunications   segment,   included  in  equity  earnings  of
     associated companies, net of impairments.
.    A $20 million gain  related to the final  settlement  of escrowed  proceeds
     from the  fourth-quarter  2002 sale of Corning Precision Lens,  recorded as
     income from discontinued operation.

Third-Quarter Operating Results
Corning's  third-quarter  sales of $1.006  billion  increased 4 percent over the
previous quarter's sales of $971 million. The sequential increase was the result
of  continued  growth of the  Display  Technologies  segment and  stronger  than
expected sales in the Telecommunications segment.

The company's operating  performance remained strong with gross margins reaching
40 percent  versus 36 percent last quarter.  Corning  continued to record strong
quarterly equity earnings from Samsung Corning  Precision Glass Co., Ltd and Dow
Corning Corporation.

Sales  for the  Display  Technologies  segment  grew 6 percent  to $295  million
compared to $277 million for the second  quarter.  Liquid crystal  display (LCD)
glass volume grew sequentially 4 percent and year-over-year it increased greater
than 70 percent.  Pricing for the quarter  remained  stable.  Net income for the
segment  increased 5 percent to $142  million  from $135 million in the previous
quarter.

Telecommunications segment sales were $412 million, a 5 percent improvement over
second-quarter  sales of $392 million. The segment recorded a net loss of $1.820
billion versus a net loss of $21 million in the previous quarter,  primarily due
to goodwill,  fixed assets and equity method  investment  impairment  charges of
$1.837 billion.  Fiber volume increased more than 20 percent  sequentially while
pricing was essentially flat. The segment's  third-quarter results reflected the
strength of the company's fiber and cable and hardware and equipment  volumes in
North America,  principally  driven by its participation in Verizon's ramp up of
its fiber-to-the-premises  project. Corning said that its fiber exports to China
have been impacted by the recent anti-dumping preliminary  determination but not
to the levels originally anticipated.

Environmental  Technologies  segment  sales  for the  third  quarter  were  $136
million, a decline from the previous quarter's sales of $141 million.  Quarterly
sales were  impacted by a recent  slowdown in diesel  products  retrofit  sales.
Segment  earnings  were  down  primarily  due  to  disappointing   manufacturing
performance  and  higher  development  spending  on  diesel  products.  The Life
Sciences segment saw  third-quarter  revenues and earnings off slightly from the
previous quarter.

Cash Flow/Liquidity Update
Corning  ended  the  third  quarter  with $1.7  billion  in cash and  short-term
investments,  an increase from the previous  quarter's  balance of $1.6 billion.
The improved cash flow  performance was primarily due to the receipt of customer
deposits and proceeds from  divestitures.  The company's  debt-to-capital  ratio
increased to 42 percent versus 31 percent at the end of last quarter as a result
of the loss in the third quarter.

"Putting  aside the  noncash  accounting  charges,  we had a very  strong  third
quarter," James B. Flaws, vice chairman and chief financial  officer,  said. "We
surpassed a billion  dollars in  quarterly  sales,  we  continued to improve our
gross margins, and we again experienced strong cash flow," he said.

Fourth-Quarter Outlook
The company said that it expects fourth-quarter sales to be in the range of $950
million  to $1  billion  and  earnings  per share in the range of $0.10 to $0.12
before  special items.  This earning per share estimate is a non-GAAP  financial
measure and excludes any previously announced special items. A reconciliation of
the non-GAAP  financial estimate is on the company's Investor Relations web site
and accompanies  this news release.  Corning expects that foreign exchange rates
will remain stable, and that its gross margin will be in the range of 37 percent
to 38 percent.

In its  Display  Technologies  segment,  Corning  expects  that  its  LCD  glass
sequential  sales volume will  increase  between 3 percent and 10 percent,  with
continued  stable  pricing.  The  company  expects  to bring on some  additional
capacity  this  quarter,  but it  said  that  current  customer  demand  exceeds
Corning's ability to supply the market.

Wendell P. Weeks,  president and chief operating officer, said that the consumer
electronics industry has recently begun to reduce retail pricing on LCD monitors
and LCD  televisions.  "We are now seeing some  historically  low prices for LCD
monitors,  which we  believe  in turn,  will  drive  retail  sales in the fourth
quarter.  It is our belief  that the global LCD glass  market  volume  will grow
approximately  60 percent  this year,  and  Corning's  glass volume will grow 65
percent to 70 percent this year. It is important to note that the pace of growth
is subject to normal business  factors,  including the level of inventory supply
within the supply chain," Weeks said.

In the  Telecommunications  segment, the company anticipates that fourth-quarter
fiber volumes will decline 10 percent to 20 percent, reflecting typical seasonal
declines in North America and greater  Europe,  while volumes in China should be
similar to the third quarter. Fourth-quarter pricing declines are expected to be
less than 5 percent.

Presentation of Information in this News Release
Corning's  earnings  estimate  for the fourth  quarter  is a non-GAAP  financial
measure as it excludes the impact of any potential  gains or losses arising from
previously  announced  restructuring  actions;  any  potential  gains or  losses
arising from debt repurchases or debt retirements;  and any further  adjustments
to the  asbestos  settlement  reserve  required by movement in  Corning's  stock
price. The company  believes  presenting  earnings  estimates that exclude these
items is helpful in understanding  Corning's  operating  results.  This earnings
estimate     is     reconciled      on     the     company's      website     at
www.corning.com/investor_relations and accompanies this news release.

(1)  Non-direct  research,  development and  engineering  expenses are allocated
     based upon direct project spending for each segment.
(2)  Interest  expense is allocated to segments based on a percentage of segment
     net operating assets.  Consolidated  subsidiaries with independent  capital
     structures do not receive additional allocations of interest expense.
(3)  Many of Corning's  administrative  and staff  functions  are performed on a
     centralized  basis.  Where  practicable,  Corning charges these expenses to
     segments  based upon the extent to which each  business  uses a centralized
     function. Other staff functions, such as corporate finance, human resources
     and legal are allocated to segments primarily as a percentage of sales.
(4)  (Loss)  income  before  minority  interests  and equity  (losses)  earnings

                  CORNING INCORPORATED AND SUBSIDIARY COMPANIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


1.   Restructuring, Impairment and Other Charges and (Credits)

In the third quarter of 2004, we recorded net charges of $1,794 million  ($1,798
million after-tax and minority interest)  included in restructuring,  impairment
and other charges and (credits). A summary of the charges/(credits) follows:

(a)  Telecommunications  segment charges  totaling  $1,802 million  included the
     following:

     .    Goodwill - Pursuant to  Financial  Accounting  Standards  Board (FASB)
          Statement of Financial  Accounting Standards (SFAS) No. 142, "Goodwill
          and Other  Intangible  Assets,"  goodwill is required to be tested for
          impairment  annually at the reporting  unit level.  The reporting unit
          for our Telecommunications  segment goodwill is our Telecommunications
          operating segment. While our annual goodwill recoverability assessment
          is  completed  in the fourth  quarter,  it is the  culmination  of our
          annual  strategic  planning  process  that runs from June to  October.
          Management  performed an  assessment  in the third quarter of 2004 and
          reviewed the outcome with  Corning's  board of directors on October 6,
          2004. The result of this strategic  review is that we have lowered our
          estimates  and  projections  for the long-term  revenue  growth of the
          Telecommunications segment.

          Based  on our  updated  estimates  for  the  long-term  growth  of the
          Telecommunications  segment,  management concluded that the fair value
          of the  Telecommunications  segment  was  below its  carrying  amount.
          Accordingly,  we recorded an  impairment  charge of $1,420  million to
          reduce the carrying  value of goodwill to its estimated  fair value of
          approximately $120 million.

     .    Fixed  Assets - As a result of the lowered  long-term  outlook for the
          Telecommunications  segment  discussed  above,  Corning recorded asset
          impairment  charges of $374 million in  accordance  with SFAS No. 144,
          "Accounting  for the  Impairment  or Disposal of  Long-Lived  Assets."
          These charges  primarily  relate to the permanent  abandonment  of the
          unfinished  phase II expansion of the Concord,  North Carolina optical
          fiber plant. This portion of the facility was only partially completed
          before Corning mothballed the entire Concord plant in October 2002.

     .    Loss on sale of business - Corning completed the  previously-announced
          sale  of its  frequency  controls  business  for net  proceeds  of $80
          million and recorded a loss of $14 million.

     .    Other - Corning  recorded net credits of $6 million for adjustments to
          prior years' restructuring and impairment charges.

(b)  In the third quarter of 2004,  Corning  completed the final sale of Corning
     Asahi Video  Products  Company assets to Henan Anyang CPT Glass Bulb Group,
     Xinyi Electronic Glass, Co., LTD, a Chinese corporation. In connection with
     this asset  sale,  Corning  recorded a gain of $8 million  before  minority
     interest.






2.   Asbestos Settlement

On  March  28,  2003,  we  announced  that we had  reached  agreement  with  the
representatives  of asbestos  claimants  for the  settlement  of all current and
future asbestos claims against us and Pittsburgh  Corning  Corporation  ("PCC"),
which might arise from PCC products or  operations.  Accordingly,  we recorded a
charge of $298  million in the first  quarter of 2003.  The charge  included the
value of 25 million  shares of Corning  common stock that we will  contribute as
part of the settlement.  Also at that time, we indicated that any changes in the
value of our common stock  contribution  would be  recognized  in our  quarterly
results through the date of  contribution to the settlement  trust. As required,
we recorded a mark-to-market  credit of $50 million in the third quarter of 2004
reflecting the decrease in Corning's  common stock from June 30 to September 30,
2004.  Beginning  with the first  quarter of 2003,  we have  recorded  total net
charges of $429 million to reflect the initial  settlement and to mark-to-market
the value of our common stock. We will make our  contributions to the settlement
trust under the agreement after the plan is approved,  becomes  effective and is
no longer subject to appeal.

3.   Long-Term Debt

In the third  quarter of 2004,  we issued 6 million  shares of common  stock and
paid  $4  million  in  cash in  exchange  for  57,500  of our  3.5%  convertible
debentures  with a book value of $58 million.  In  accordance  with SFAS No. 84,
"Induced  Conversions  of Convertible  Debt," Corning  recognized a charge of $4
million reflecting the fair value of the incremental  consideration given (i.e.,
the cash) beyond those required by the terms of the debentures.

4.   Provision for Income Taxes

In the third  quarter of 2004, we increased our tax expense by $937 million as a
result of the company's  decision to establish a valuation  allowance  against a
significant  portion  of its  deferred  tax  assets,  primarily  in the U.S.  We
performed  an  assessment  of  positive  and  negative  evidence  regarding  the
realization  of our net  deferred  tax  assets  as  required  by SFAS  No.  109,
"Accounting  for Income  Taxes" (SFAS 109).  SFAS 109 requires  that a valuation
allowance be  established  when it is more likely than not that all or a portion
of a deferred tax asset will not be  realized.  SFAS 109 further  requires  that
"greater  weight be given to  previous  cumulative  losses  than the outlook for
future profitability when determining whether deferred tax assets can be used."

We  have  incurred   significant  losses  in  the  U.S.  due  primarily  to  the
restructuring   and   impairment   charges   and   operating   losses   in   our
Telecommunications  segment  over the last four years.  As a result of the third
quarter  impairment  charges and the lowering of our  long-term  outlook for the
Telecommunications  segment,  our largest U.S.  business,  we  concluded  that a
valuation  allowance  against these tax assets is required until  realization is
more assured.

5.   Equity Investments

In the third quarter of 2004, Corning recorded impairment charges of $35 million
to write-down certain  Telecommunications  segment equity-method  investments to
their estimated fair value. As a result of Corning's revised  Telecommunications
segment outlook,  we determined that these  investments were no longer strategic
assets. Accordingly, we recorded a charge to fully impair the book values of our
investments in these entities.  These impairment charges are included in "equity
in earnings of associated  companies,  net of  impairments" in the statements of
operations.

6.   Discontinued Operation

In the third quarter of 2004, we reached a final  settlement  agreement  with 3M
Company for  disbursement  of funds held in escrow as part of our December  2002
sale of our precision  lens business.  Accordingly,  we recognized a gain of $20
million  upon receipt of these  proceeds.  This gain is included in "income from
discontinued operation" in the statements of operations.

                  CORNING INCORPORATED AND SUBSIDIARY COMPANIES
     RECONCILIATION OF NON-GAAP FINANCIAL MEASURE TO GAAP FINANCIAL MEASURE
                      Nine Months Ended September 30, 2004
           (Unaudited; amounts in millions, except per share amounts)

--------------------------------------------------------------------------------
Corning's  earnings  excluding certain items for the third quarter is a non-GAAP
financial  measure  within the meaning of  Regulation  G of the  Securities  and
Exchange  Commission.  The company believes  presenting  earnings estimates that
exclude these items is helpful in  understanding  Corning's  operating  results.
This non-GAAP  measure is not in accordance with and should not be considered an
alternative  of  measurements   required  under  generally  accepted  accounting
principles  (GAAP).  A detailed  reconciliation  is provided below outlining the
differences between this non-GAAP measure and the directly related GAAP measure.

(a)  Corning  recorded  charges of $1.794  billion in the third quarter of 2004.
     The following charges are associated with its  Telecommunications  segment:
     $1.420  billion to impair  goodwill;  $374 million to impair  certain fixed
     assets;  and $14 million for the  completion  of the sale of the  frequency
     controls business. Also in the third quarter of 2004, Corning completed the
     final sale of Corning Asahi Video  Products  Company assets to Henan Anyang
     CPT Glass Bulb Group, Xinyi Electronic Glass, Co., LTD. and recorded a gain
     of $8 million  before  minority  interest.  Lastly,  Corning  recorded  net
     credits of $6 million  for  adjustments  to prior  year  restructuring  and
     impairment charges.

(b)  As part of Corning's  asbestos  settlement  arrangement to be  incorporated
     into the Pittsburgh Corning Corporation  reorganization  plan, Corning will
     contribute,  when the  reorganization  plan becomes  effective,  25 million
     shares of Corning  common  stock to a trust.  This  portion of the asbestos
     liability requires  quarterly  adjustment based upon movements in Corning's
     common stock price prior to contribution of the shares to the trust. In the
     third  quarter of 2004,  Corning  recorded a credit of $50  million for the
     change in its common stock price of $11.08 at September  30, 2004  compared
     to $13.06, the common stock price at June 30, 2004.

(c)  From time to time,  Corning  may  repurchase  or retire  debt,  which could
     result in a gain or loss during the quarter.  In the third quarter of 2004,
     Corning  retired certain  amounts of its 3.5%  convertible  bonds due 2008,
     resulting in a loss of $4 million.

(d)  In the third quarter of 2004,  Corning increased income tax expense by $937
     million  as a result  of the  company's  previously-announced  decision  to
     provide a valuation allowance against a significant portion of its deferred
     tax assets.

(e)  This amount  reflects  charges  for  impairments  of certain  non-strategic
     equity method investments in Corning's Telecommunications segment.

(f)  This  gain  relates  to the  final  settlement  of the  sale  of  Corning's
     precision lens business to 3M Company.

        This schedule will be updated as additional announcements occur.
        ----------------------------------------------------------------

(a)  As part of Corning's  asbestos  settlement  arrangement to be  incorporated
     into the Pittsburgh Corning Corporation  reorganization  plan, Corning will
     contribute,  when the  reorganization  plan becomes  effective,  25 million
     shares  of  Corning  common  stock to a trust.  The  common  stock  will be
     contributed to the trust,  after the plan has been approved by the asbestos
     claimants and bankruptcy court. The portion of the asbestos liability to be
     settled  in common  stock  requires  adjustment  each  quarter  based  upon
     movements in  Corning's  common  stock price prior to  contribution  of the
     shares to the trust.  In the fourth quarter of 2004,  Corning will record a
     charge or credit for the change in its common  stock  price as of  December
     31, 2004 compared to $11.08, the common stock price at September 30, 2004.

(b)  From time to time,  Corning may need to make  adjustments to estimates used
     in the determination of prior year  restructuring  and impairment  charges,
     which could result in a gain or loss during the quarter.

(c)  From time to time,  Corning  may  repurchase  or retire  debt,  which could
     result in a gain or loss during the quarter.


Please note that the  company  may pursue  other  financing,  restructuring  and
divestiture  activities at any time in the future, and that the potential impact
of these events is not included within Corning's third quarter guidance.
