                      Corning Reports First-Quarter Results

                          Performance exceeds guidance
                      Continued strength seen in LCD market

CORNING,  N.Y.  -- Corning  Incorporated  (NYSE:GLW)  today  announced  that its
first-quarter   results   exceeded   quarterly   guidance  and  sales  increased
sequentially  for the first time in two years.  The company said sales were $746
million and that it recorded a net loss of $205 million or $0.17 per share. This
net loss includes $201 million or $0.17 per share of charges  primarily  related
to the previously announced asbestos litigation settlement and restructuring and
impairment charges.

James R. Houghton, chairman and chief executive officer, said, "We are extremely
pleased with the improvement in our quarterly  performance.  Our results reflect
stronger  than  expected  demand for fiber and cable in Japan and the  continued
strength of our technologies  businesses,  particularly the Display Technologies
and  Environmental  Technologies  businesses."  Houghton  said that the  company
continues  to focus on its  goal of  returning  to  profitability  by the  third
quarter of this year. "We are seeing significant improvement in our gross margin
and lower operating costs due to our restructuring  efforts over the past year,"
he said.

Previously Announced Charges
Corning said its first-quarter results include net charges totaling $345 million
($201 million after-tax and minority interest) or $0.17 per share. These include
the following:
     .    A previously announced charge of $298 million ($192 million after-tax)
          for asbestos litigation related to Pittsburgh Corning Corporation.
     .    Net restructuring  and impairment  charges of $51 million ($12 million
          after-tax and minority  interest) related to the previously  announced
          decisions  to shut down  Corning  Asahi  Video  (CAV) and the  optical
          switching  business,  offset by adjustments to the company's  existing
          restructuring reserves.
     .    A net  gain  of $4  million  ($3  million  after-tax)  related  to the
          repurchase of debt using cash and common stock.

First-Quarter Operating Results
Sales for the quarter of $746  million  represent  a  sequential  increase  from
fourth-  quarter  sales of $736 million.  Telecommunications  segment sales were
$352 million,  compared to  fourth-quarter  sales of $363 million.  Fiber volume
increased  approximately  15 percent  sequentially due to stronger than expected
demand in Japan and China,  offset by  continued  softness in North  America and
Europe.  Sequential  price declines,  as expected,  were in the 10 to 15 percent
range for the quarter.

Corning Technologies  recorded  first-quarter sales of $388 million, an increase
over  fourth-quarter  sales of $367 million.  Corning's display glass sales were
fueled by strong  demand for flat screen  desktop  monitors,  the  popularity of
notebook  computers  and  growing  interest  in  liquid  crystal  display  (LCD)
televisions.  Sequential  quarterly  display  glass  volume  gains were about 10
percent  and LCD glass  pricing  was stable.  Corning's  environmental  products
business  experienced  volume  increases  worldwide.  Both of  these  businesses
benefited from favorable exchange rates.

Corning's  first-quarter  results benefited from the initial  recognition of $17
million of equity earnings from Dow Corning Corporation.  Corning's total equity
earnings for the first quarter were $59 million.

Liquidity Update
Corning  said that it ended the first  quarter  with  $1.85  billion in cash and
short-term investments, a decline from $2.1 billion at the end of last year. The
decline was primarily due to the use of cash to retire debt. Operating cash flow
included a $191 million federal income tax refund.

In the first quarter,  Corning used $251 million for scheduled  debt  repayments
and open market repurchases.  In addition,  Corning exchanged 6.5 million shares
of Corning common stock for debt with an accreted value of $43 million.  Corning
said that it might continue from  time-to-time  to retire its debt securities in
open market,  privately  negotiated  or other  transactions.  Corning  ended the
quarter with a  debt-to-capital  ratio of 45.6  percent,  down from 46.7 percent
from year-end.

Second-Quarter Outlook
Corning  said that it  expects  second-quarter  sales to be in the range of $715
million to $745 million.  It also anticipates  results in the range of a loss of
$0.02 per share to income of $0.01 per share.  These results  exclude the impact
of  previously  announced  restructuring  charges  and  any  adjustments  to the
asbestos settlement reserve required by movement in Corning's stock price.

Corning expects continued strong  performance from its LCD glass business,  with
sequential  volume gains of about 10 percent and stable pricing.  Second quarter
fiber volumes are expected to decline  sequentially by about 25 percent,  driven
by the seasonal  slowdowns in Japan and the continued  softness across the North
American market.

Corning  said it also  continues to explore a number of options for its Photonic
Technologies business and expects to reach a decision by mid-year.

James B. Flaws, vice chairman and chief financial officer,  said, "Putting aside
the strength of our fiber and cable  business in Asia last  quarter,  we are not
seeing a lift in our telecommunications  businesses,  but this does not surprise
us. Global events,  the long winter in North America and the overall  malaise in
the economy appear to be delaying any potential seasonal improvements in telecom
sales. We anticipate that with normal  seasonality in the Japanese fiber market,
there will be a pick up in volume in the second half of the year.

Flaws said that the company has been closely  monitoring  external trends across
all its markets and said,  "While it is too early to tell, there are indications
that a general  economic slow down in North America may affect some of Corning's
businesses  such  as  Environmental   Technologies  where  potential   inventory
corrections in the auto industry could dampen second-quarter sales. However, our
plan to return to profitability is mostly dependent on strong performance of our
display business and our own cost cutting actions. Our first-quarter performance
on these fronts was strong and we remain optimistic that our profitability  goal
is achievable."

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



1.   Restructuring, Impairment and Other Charges and Credits

In the first quarter of 2003,  Corning recorded charges for the shut-down of the
conventional  video components  business and the optical  switching product line
which were  announced on April 15, 2003 and  February  13,  2003,  respectively.
Corning also recorded  credits related to the  restructuring  reserve  discussed
below.

Conventional video components business

Corning  Asahi Video  Products  Company,  a 51% owned  consolidated  subsidiary,
(conventional  video  components  business,  or CAV), is a manufacturer of glass
panels and funnels for use in conventional  tube  televisions and is reported in
the Technologies segment.

On April 15,  2003,  Corning  announced  that it had agreed  with its partner to
cease  production.  Corning  impaired the long-lived  assets of this business to
estimated  salvage  value and  recorded a charge of $62  million,  ($19  million
after-tax  and  minority  interest).  Restructuring  costs  are  expected  to be
recorded  in the  second  quarter  and total $80  million to $110  million  ($20
million to $35 million  after-tax and minority  interest).  Corning  expects the
restructuring  costs to require  $40  million to $65  million in cash  spending.
Corning  has agreed with its partner to a shared  funding  arrangement  based on
proportional partnership interests.

Optical Switching

Corning recorded a charge of $17 million  associated with the  discontinuance of
the optical switching product line in the photonic  technologies business due to
the  downturn  in the  telecommunications  industry.  In  addition  to the first
quarter charges,  Corning expects to record charges of $10 million in the second
quarter for certain exit costs.

Impairment of Cost Investments

In the first  quarter,  Corning  recorded a $5 million  ($3  million  after-tax)
charge for other than temporary  declines in certain  investments  accounted for
under the cost method in the Telecommunications segment.

Credits

The current  restructuring  reserve continues to be evaluated as plans are being
executed.  As a  result,  there  may be  additional  charges  or  reversals.  In
addition,  since the restructuring  program is an aggregation of many individual
plans  currently  being  executed,  actual costs have  differed  from  estimated
amounts.  During the first  quarter,  Corning  recorded  credits of $33  million
related to revised cost estimates of existing  restructuring  plans of which $24
million related to employee  separation and exit costs, while $9 million related
to  adjustments  to  assumed  salvage  values  of assets  that  were  previously
impaired.

2.   Asbestos Settlement

On March 28, 2003,  Corning  announced  that it had reached  agreement  with the
representatives  of asbestos  claimants  for the  settlement  of all current and
future asbestos claims against Corning and Pittsburgh Corning Corporation (PCC),
which might arise from PCC products or operations.






The agreement is expected to be incorporated into a settlement fund as part of a
reorganization  plan  for  PCC.  The  plan  will  be  submitted  to the  federal
bankruptcy court in Pittsburgh for approval,  and is subject to a favorable vote
by 75 percent of the asbestos claimants voting on the PCC  reorganization  plan.
Corning will make its  contributions to the settlement trust under the agreement
after the plan is approved and no longer subject to appeal. The approval process
could take one year or longer.

Corning's  settlement  will  require  the  contribution,  when the plan  becomes
effective,  of Corning's equity interest in PCC, its one-half equity interest in
Pittsburgh  Corning  Europe N.V.  (PCE), a Belgian  corporation,  and 25 million
shares of Corning  common  stock.  Corning also will make cash  payments  with a
current  value of $130  million  over  six  years  beginning  in June  2005.  In
addition,  Corning  will  assign  insurance  policy  proceeds  from its  primary
insurance  and a portion  of its  excess  insurance  as part of the  settlement.
Corning recorded a charge of $298 million ($192 million  after-tax) in the first
quarter.  The carrying value of Corning's  stock in PCE and the fair value as of
March 31, 2003, of 25 million shares of Corning common stock have been reflected
in current liabilities. The remaining $130 million, representing the net present
value of the cash  payments,  discounted  at 5.5%,  is  recorded  in  noncurrent
liabilities.  Any changes in the value of Corning's  common  stock  contribution
will need to be recognized in Corning's  quarterly  results  through the date of
contribution to the settlement trust.

3.   Gain on Repurchases of Debt, Net of Inducements

During the first quarter of 2003,  Corning  repurchased and retired 298,500 zero
coupon convertible debentures with an accreted value of $231 million in exchange
for cash of $189  million in a series of  open-market  repurchases.  Also in the
first  quarter  Corning  issued 6.5 million  shares of treasury  common stock in
exchange for zero coupon  convertible  debentures  with an accreted value of $43
million.  Corning  recorded  a net gain of $4  million  ($3  million  after-tax)
associated  with  retirements of its zero coupon  convertible  debentures in the
first  quarter.  The  increase  in equity  due to the  issuance  of shares  from
treasury stock was $77 million.

4.   Income Tax

In the first quarter of 2003, the effective tax benefit rate  excluding  certain
items  such  as  restructuring,   impairment,   asbestos   settlement  and  debt
transactions was 30%.
