                 Corning Reports First-Quarter Net Income Gains

         Strong performance in Display, Environmental and Life Sciences
             Company's 2004 LCD volume growth may exceed 50 percent

CORNING,  N.Y. -- Corning  Incorporated  (NYSE:  GLW) today  announced  that its
first-quarter  sales were $844  million  and its net  income was $55  million or
$0.04 per share. Net income includes  previously  announced after-tax charges of
$60 million or $0.04 per share.

James R.  Houghton,  chairman  and chief  executive  officer,  remarking  on the
quarter  results  said,  "We  are  extremely   pleased  with  our  first-quarter
performance.  Our sales exceeded our  expectations  and we were pleased with our
improved  manufacturing   performance  that  contributed  to  our  gross  margin
improvement  to more than 35 percent.  In addition,  we continued to  experience
strong equity earnings."

Corning said that its first-quarter  results include previously announced pretax
charges  of $76  million  ($60  million  after-tax  or $0.04 per  share).  These
include:
..    Restructuring,  impairment  and other  charges of $34 million  ($21 million
     after-tax  and  minority  interest)  primarily  related  to the  closure of
     Corning's  high purity fused silica  manufacturing  facility in Charleston,
     S.C.

..    A $23 million charge ($21 million  after-tax)  related to Corning's ongoing
     debt reduction program.

..    A $19 million charge ($18 million after-tax) to reflect the increase in the
     market  value of  Corning  common  stock to be  contributed  to settle  the
     asbestos litigation related to Pittsburgh Corning Corporation.

First-Quarter Operating Results
The company's first-quarter sales of $844 million exceeded its guidance range of
$770  million  to  $830   million  and   increased   $24  million   compared  to
fourth-quarter sales of $820 million. The sales increase was driven by continued
strong demand for liquid crystal display (LCD) glass in the Display Technologies
segment and solid sales  increases in the  Environmental  Technologies  and Life
Sciences segments,  offset by an expected decline in Telecommunications  segment
sales.

The company's net income of $55 million  increased  sequentially  by $84 million
compared  to a $29  million  net  loss in the  fourth  quarter.  The net  income
increase  was  primarily  the result of  improved  manufacturing  in many of its
businesses  and the  continued  growth of LCD glass,  which  resulted in a total
gross  margin of 35.5  percent in the quarter  compared  to 29.5  percent in the
fourth  quarter;  a  significant  increase in equity  earnings  driven by strong
operating  performance  at Samsung  Corning  Precision  Glass Co.,  Ltd. and Dow
Corning Corporation; and a lower level of after-tax special charges in the first
quarter.

Segment Results
Due to a change in its operating  segments,  Corning will now separately  report
four key operating segments beginning in the first quarter of this year.

Corning's Display Technologies segment sales were $230 million compared to sales
of $199 million in the previous  quarter.  Sequential sales of LCD glass grew 16
percent due to volume  increases  of 14 percent,  stable  pricing and  favorable
foreign exchange rates.  Display's strong  manufacturing  performance and the 30
percent increase in equity earnings from Samsung Corning  Precision  contributed
to the  quarterly  results.  The  display  segment  recorded  net income of $118
million in the quarter, compared to $81 million in the previous quarter.

The  Environmental  Technologies  segment's  quarterly  sales were $141  million
versus sales of $123 million in the previous quarter. The segment's record sales
were driven by strong thin-wall and ultra thin-wall  automotive  substrate sales
in all regions. Improved manufacturing performance in the quarter contributed to
the segment's  increased net income. In April of this year,  Corning  officially
dedicated its $200 million diesel  substrates  facility to meet the  anticipated
demand of the emerging diesel emission control market.

The Life Sciences segment also experienced  record sales of $79 million compared
to the previous  quarter  sales of $66 million.  Quarterly  sales and net income
gains were due to stronger  than  expected  seasonal  volume  increases for life
science products.

Corning's  Telecommunications  segment  sales were $312 million and net loss was
$43 million for the quarter, a decline from fourth-quarter sales of $357 million
and a net loss of $18  million.  The  fourth-quarter  loss  included net credits
related to restructuring of approximately $23 million after-tax. Quarterly fiber
volume  declined 7 percent  sequentially,  slightly  better  than the  company's
revised March  guidance of 10 percent to 15 percent due to  particularly  strong
March sales in North America. Price declines were again moderate.

Of the $24 million sequential sales increase for the company,  approximately $10
million  is  related  to more  favorable  foreign  exchange  rates in the  first
quarter.

Cash Flow/Liquidity Update
Corning  ended the first  quarter  with  approximately  $1.5 billion in cash and
short-term  investments,  an increase of about $200  million  from year end. The
increase  was  primarily  due to proceeds  of $400  million  resulting  from the
company's  debt  offering,  offset by $140  million of cash used to reduce debt.
Corning's  debt-to-capital  ratio was 33.1 percent at the end of the quarter, an
improvement from 33.8 percent at year end.

Second-Quarter Outlook
Corning  said that it  expects  second-quarter  sales to be in the range of $900
million to $950 million,  with earnings per share in the range of $0.07 to $0.09
before  special  items.  This  estimate is a non-GAAP  financial  measure and is
reconciled on the company's  investor  relations Web site.  Corning  anticipates
that foreign  exchange  rates will remain stable in the second  quarter and that
gross margins will be in the range of 34 percent to 35 percent.

In the  Telecommunications  segment,  Corning expects a sequential  fiber volume
increase  between 10 percent and 15 percent due to typical  seasonality in North
America and greater Europe,  along with  incremental  volume increases in Japan.
Pricing declines are again expected to be moderate at less than 5 percent in the
quarter.

Corning  anticipates second quarter revenues for both its environmental and life
sciences segments to be consistent with the first quarter.

The company expects to remain sold out of LCD glass in the quarter, and it plans
to bring on additional capacity throughout the year, expanding larger-generation
manufacturing  capabilities.  Corning  remains the only  commercial  supplier of
Generation  6 glass to date and Samsung  Corning  Precision  is expected to ship
samples  of  Generation  7 glass in the  third  quarter.  Sequential  volume  is
expected to increase  by 10 percent to 15 percent for the  quarter.  Pricing for
the second quarter should remain stable.

James B. Flaws, vice chairman and chief financial officer,  said, "The continued
demand for flat  screen  monitors  and  notebook  computers  will  drive  strong
second-quarter growth for our display segment.  While we do not yet have updated
industry  growth  estimates  for the full year, we are now  optimistic  that the
overall LCD glass market growth will be near 50 percent. Corning's first-quarter
results  and  second  quarter  forecast  suggest  that  volume  growth  for  our
wholly-owned  business may likely exceed 50 percent. This increase appears to be
the  result  of  the  market's  movement  to  larger-size  glass  and  Corning's
leadership in the production of Generation 5 and 6 size glass substrates."

Flaws said that the popularity of LCD televisions also continues to grow, noting
that in the first  quarter  alone the  industry  shipped more than 2 million LCD
televisions.  "This is almost half of the entire LCD television market shipments
of 4.5 million televisions last year," he said. "Based on market experience, and
assuming a drop in retail prices and a healthy economy, we remain confident that
this will be a robust market for the foreseeable future," he said.

Corning said that its equity  venture,  Dow  Corning,  will take a charge in the
second quarter as a result of some restructuring and cost reductions.  Corning's
share of these charges will be approximately $10 million and will be reported as
a special charge for the quarter.

"Overall,  we are very pleased with our  progress in the first  quarter,"  Flaws
said,  "And we are excited  about our  potential  revenue  growth for the second
quarter.  We are gaining momentum and we look forward to delivering on our three
priorities:   maintaining   our  financial   health,   improving  the  company's
profitability and continuing to invest in future growth opportunities."

Presentation of Information in this News Release
Corning's  earnings  estimate  for the second  quarter  is a non-GAAP  financial
measure as it excludes any  potential  gains or losses  arising from  previously
announced  restructuring  actions,  any  further  adjustments  to  the  asbestos
settlement reserve required by movement in Corning's stock price and income from
discontinued operations. 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  investor  relations Web
site.

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

1.   Restructuring, Impairment and Other Charges and Credits

In the first  quarter of 2004,  we recorded net  restructuring,  impairment  and
other  charges  and credits  totaling  $34 million  ($21  million  after tax and
minority interest). A summary of these charges and credits follow:

..    We recorded $39 million of accelerated  depreciation and $1 million of exit
     costs  relating  to  the  final  shutdown  of our  semiconductor  materials
     manufacturing facility in Charleston,  South Carolina,  which we previously
     announced in the fourth quarter of 2003.

..    We recorded credits of $6 million  primarily  related to proceeds in excess
     of assumed salvage values for assets that were previously impaired.


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  ($192  million  after tax) in the first quarter of 2003.
The charge included the value of 25 million shares of Corning common stock which
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  charge of $19
million  ($18 million  after tax) in the first  quarter of 2004  reflecting  the
increased fair value of Corning's common stock. Since the first quarter of 2003,
we have  recorded  total  charges of $432 million  ($282  million  after tax) to
reflect the settlement and to mark-to-market the value of our common stock.


3.   Long-Term Debt

In March 2004, we issued $400 million of senior  unsecured  notes, of which $200
million  aggregate  principal amount of 5.90% notes mature on March 15, 2014 and
$200 million aggregate principal amount of 6.20% notes mature on March 15, 2016.
These senior unsecured notes were issued under our existing $5 billion universal
shelf registration statement,  which became effective in March 2001. We realized
net proceeds of approximately  $396 million from the issuance of these notes. We
will pay interest on these senior unsecured notes on each March 15 and September
15. These senior unsecured notes are redeemable in whole or in part at any time.

During the first  quarter of 2004,  we issued 22 million  shares of common stock
and paid $24 million in cash in exchange for 3.5% convertible  debentures with a
book value of $213 million. In addition, we repurchased 150 thousand of our zero
coupon convertible debentures with a book value of $119 million for $117 million
in cash.  As a result of these  transactions,  we recorded a loss of $23 million
($21 million after tax) in first quarter 2004.


4.   Income Tax

In the  first  quarter  of  2004,  the  effective  tax  benefit  rate  excluding
restructuring,   impairment,   and  other  charges  and  credits,  the  asbestos
settlement, and loss on repurchases and retirement of debt transactions was 33%.

(1) This charge primarily related to the consolidation of our high purity fused
silica manufacturing facility in Charleston, South Carolina. This charge also
included a credit related to prior years' restructuring charges, principally in
the Telecommunications segment.

(2) As part of Corning's asbestos settlement for Pittsburgh Corning, Corning
will be contributing 25 million shares of Corning common stock to the trust,
along with some cash. The common stock is currently expected to be contributed
to the trust in 2004, after the claimants have approved the plan and all appeals
have been resolved. Until the common stock is contributed to the trust, changes
in its market value will be recognized in our quarterly results. At the end of
the first quarter, we recorded a charge of $19 million pre tax and $18 million
after tax to reflect the increase in Corning's stock price over the past quarter
from $10.43 to $11.18.

(3) This charge is related to debt-for-equity exchanges pertaining to our 3.5%
convertible bonds due in 2008.

                  ---------------------------------------------

Quarter 2, 2004

--------------------------------------------------------------------------------
Corning's earnings estimate for the first quarter is a non-GAAP financial
measure as it excludes certain items listed below. The company believes
presenting earnings estimates that exclude these items is helpful in
understanding Corning's operating results.

Restructuring, impairment and other charges and (credits) (1)

Asbestos settlement (2)

Gain (loss) on repurchases and retirements of debt, net (3)

Equity in earnings of associated companies (4)


(1) Corning expects to record a gain from the sale of CAV equipment to the Henan
Anyang CPT Glass Bulb Group, Xinyi Electronic Glass, Co., LTD. The sale is
expected to be completed over the remainder of 2004.

(2) As part of Corning's asbestos settlement for Pittsburgh Corning, Corning
will be contributing 25 million shares of Corning common stock to the trust,
along with $138 million in cash. The common stock is expected to be contributed
to the trust in 2004, after the claimants have approved the plan and all appeals
have been resolved. Until the common stock is attributed to the trust, the
change in Corning's stock price from the closing price of $11.18 on March 31,
2003 to the closing price on June 30, 2004 will be recognized in our first
quarter results.

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

(4) Dow Corning, a 50% equity venture, will record restructuring charges in the
second quarter. Corning's share of those charges will be approximately $10
million and will be recorded in equity earnings of associated companies.

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 fourth quarter guidance.
