                     Corning Reports Second-Quarter Results

                 Company posts 15 percent sequential sales gain

CORNING, N.Y. -- Corning Incorporated (NYSE:GLW) today announced  second-quarter
sales of $971 million and net income of $108  million,  or $0.07 per share.  Net
income includes net after-tax charges of $61 million, or $0.04 per share.

"We clearly  exceeded our  expectations  for the  quarter,"  James R.  Houghton,
chairman and chief executive  officer,  said. "We saw very strong performance in
our Telecommunications and Display Technologies segments. In addition,  this was
our sixth quarter of sequential revenue growth," he said.

Corning's  second-quarter  net  after-tax  charges of $61 million,  or $0.04 per
share, include:

..    A $47 million charge ($45 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.
..    A $34 million gain ($14 million after-tax and minority interest) from
     restructuring activities, primarily related to the sale of Corning Asahi
     Video Products Company assets.
..    A $9 million charge ($9 million after-tax) related to Corning's ongoing
     debt reduction program.
..    Charges totaling $21 million in equity earnings related to restructuring
     actions at Dow Corning Corporation and adjustments to interest liabilities
     recorded on its emergence from bankruptcy.

Second-Quarter Operating Results
The  company's  second-quarter  sales of $971 million  increased 15 percent over
first-quarter  sales of $844  million.  The  sales  improvement  was  driven  by
seasonal increases in the Telecommunications segment and continued growth in the
Display Technologies segment.

Corning's net income of $108 million  almost doubled  compared to  first-quarter
net income of $55 million.  The net income  increase was primarily the result of
higher  sales  in the  company's  Telecommunications  and  Display  Technologies
segments. In addition,  equity earnings from Dow Corning Corporation and Samsung
Corning Precision Glass Co., Ltd. were strong in the quarter.

Segment Results
Display  Technologies  segment sales grew 20 percent to $277 million compared to
first-quarter  sales of $230 million.  This increase  reflects 22 percent volume
growth in liquid crystal  display (LCD) glass and stable prices.  Second-quarter
volume growth was particularly strong in Taiwan. Segment net income increased 14
percent to $135 million compared to $118 million in the previous quarter.

Telecommunications  segment sales were $392 million and net loss was $21 million
for the quarter, compared to first-quarter sales of $312 million and net loss of
$43  million.  The  improved  quarterly  performance  was  driven  primarily  by
sequential fiber and cable volume gains in North America and Europe,  and strong
demand  for the  company's  hardware  and  equipment  products  in  part  due to
Verizon's  fiber-to-the-premises  build-out.  Fiber volume  increased 31 percent
sequentially and price declines were moderate. Corning also said that the recent
anti-dumping  preliminary  determination in China is beginning to have an impact
on fiber  exported to China.  The company is  continuing  to cooperate  with the
Chinese Ministry of Commerce to reach a final determination.

Both  Environmental  Technologies  and Life Sciences  segment sales and earnings
were about even with the first-quarter  results. The Environmental  Technologies
segment had sales of $141 million for the second quarter. The company said sales
of its diesel products  increased  sequentially and its automotive product sales
were down slightly from a record first-quarter performance. In the Life Sciences
segment,   second-quarter   sales   were  $79   million,   keeping   pace   with
stronger-than-expected first-quarter sales.

Cash Flow/Liquidity Update
Corning ended the quarter with approximately $1.6 billion in cash and short-term
investments  compared to $1.5  billion in the first  quarter.  The  increase was
primarily  due to  strong  operating  cash  flow,  which  more than  offset  the
company's capital spending.  Corning's debt-to-capital ratio was 31.2 percent at
the end of the second quarter versus 33.1 percent in the first quarter.

Third-Quarter Outlook
Corning  said  that it  expects  third-quarter  sales to be in the range of $950
million to $1 billion,  with  earnings  per share in the range of $0.10 to $0.12
before special items. This estimate is a non-GAAP financial measure and excludes
the previously announced charge of approximately $25 million pretax for the sale
of the  company's  frequency  control  business  and other  potential  gains and
charges. The non-GAAP financial estimate is reconciled on the company's Investor
Relations Web site and in the financial  statements  accompanying  this release.
Corning  expects that its gross margins will be in the range of 36 percent to 37
percent and foreign exchange rates will remain stable.

Corning is  increasing  its  estimate of capital  spending  for the year to $950
million to $1 billion.  This increase  reflects the company's  intent to keep up
with the strong growth in the LCD market, as well as the faster-than-anticipated
cash outflows for its construction projects in Taiwan.

In the Telecommunications  segment, Corning expects that sequential fiber volume
will decrease between 10 percent and 15 percent in the third quarter and pricing
declines will remain  moderate.  The company said that it expects seasonal gains
in fiber volume in North America and Europe to be offset by declines in China as
a result of the recent anti-dumping  preliminary ruling. Corning also expects to
continue to see strong hardware and equipment sales in the quarter.

Corning expects that its Display  Technologies  segment will have another strong
quarter.  Sequential volume is expected to increase approximately 10 percent for
the  quarter  and is being  limited  by the  company's  ability  to bring on new
capacity. Pricing is expected to remain stable.

"We  believe  that  we  will  remain  sold  out  of LCD  manufacturing  capacity
throughout the year," James B. Flaws, vice chairman and chief financial officer,
said.  "And we are  adding  capacity  to meet the  industry's  demand for larger
generation state-of-the-market LCD substrates," he said.

Flaws also said that Corning is pleased with the  improving  performance  of the
company's Telecommunications segment, but that it is too early to see a recovery
trend in the market. "We are encouraged by the sales we are experiencing for the
fiber-to-the-premises build-outs," he added.

Flaws  remarked  that,  "We are making  excellent  progress on our key  business
priorities,  and we believe we can sustain this momentum into the third quarter.
It  feels  good to us right  now.  We see  positive  trends  across  many of our
businesses, and we are looking forward to the third quarter."

Presentation of Information in this News Release
Corning's  earnings  estimate  for the third  quarter  is a  non-GAAP  financial
measure as it excludes any  potential  gains or losses  arising from  previously
announced  restructuring  actions;  previously announced loss on the sale of the
frequency control business;  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 in this press release.

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


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

In the second  quarter of 2004, we recorded  credits of $34 million ($14 million
after-tax and minority interest) included in restructuring, impairment and other
charges and (credits). A summary of these credits follows:

..    a $25 million gain ($8 million after-tax and minority  interest) related to
     proceeds in excess of assumed  salvage  values for assets of Corning  Asahi
     Video Products  Company that were  previously  impaired but later sold to a
     third party in China; and
..    a $9 million  credit ($6  million  after-tax)  comprised  of  reversals  of
     reserves related to prior years' restructuring charges.

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 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  charge of $47
million ($45 million  after-tax) in the second  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 $479 million  ($327  million  after-tax) to
reflect the settlement and to mark-to-market the value of our common stock.

3.   Long-Term Debt

During the second  quarter of 2004, we issued 10 million  shares of common stock
and paid $9 million in cash in exchange for 3.5%  convertible  debentures with a
book value of $98 million. As a result of these  transactions,  we recorded a $9
million charge ($9 million after-tax) relating to the retirement of debt.

4.   Dow Corning Corporation

In the second quarter of 2004,  Corning's  50-percent owned equity company,  Dow
Corning  Corporation,  recorded  a  restructuring  charge and a charge to adjust
interest liabilities due to court rulings on its emergence from bankruptcy.  Our
equity  earnings in the second  quarter of 2004 included $21 million  related to
these charges.

5.   Subsequent Event

On July 8, 2004, we announced the sale of our frequency control business,  which
is part of our  Telecommunications  segment.  The frequency control business had
2003  annual  sales of  approximately  $70  million.  We  expect  to  close  the
transaction and recognize a pretax loss  approximating  $25 million in the third
quarter of 2004.

Corning's  earnings excluding certain items for the second 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)  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 is currently
     expected to be  contributed  to the trust in 2004,  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  the  common  stock  price  prior  to
     contribution  of the shares to the trust. At the end of the second quarter,
     we  recorded a pretax  charge of $47 million  ($45  million  after-tax)  to
     reflect the  increase in  Corning's  stock price over the past quarter from
     $11.18 to $13.06.

(b)  This gain relates to restructuring activities, which is primarily comprised
     of the sale of Corning  Asahi  Video  Products  Company  assets  during the
     second quarter of 2004.

(c)  From time to time,  Corning  may  repurchase  or retire  debt,  which could
     result in a gain or loss during a quarter.  In the second  quarter of 2004,
     Corning  retired certain  amounts of its 3.5%  convertible  bonds due 2008,
     resulting in a pretax and after-tax loss of $9 million.

(d)  This amount reflects  charges of $21 million in equity earnings  related to
     restructuring  actions and adjustments to interest  liabilities recorded by
     Dow Corning Corporation on its emergence from bankruptcy.

        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 is currently
     expected to be  contributed  to the trust in 2004,  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  the  common  stock  price  prior  to
     contribution  of the  shares to the  trust.  In the third  quarter of 2004,
     Corning will record a charge for the change in its common stock price as of
     September 30, 2004  compared to $13.06,  the common stock price at June 30,
     2004.

(b)  Corning expects to record pretax charges  approximating  $18 million in the
     third quarter of 2004. In the third quarter of 2004, Corning announced that
     it reached an agreement to sell its Frequency Controls  business,  the sale
     of which is expected to generate a pretax loss  approximating  $25 million.
     Also in the  third  quarter  of 2004,  Corning  will  complete  the sale of
     Corning Asahi Video Products  Company assets to Henan Anyang CPT Glass Bulb
     Group,  Xinyi  Electronic  Glass.,  Co.,  LTD.  and  record a  pretax  gain
     approximating $7 million.

(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.
