                      Corning is Well Positioned for Growth
                        LCD TV to help drive glass demand
                      Company's financial position improved

CORNING,   N.Y.  --  Continued   investments  in  three  major  business  growth
opportunities   and  a   significantly   improved   balance  sheet  has  Corning
Incorporated  (NYSE:  GLW)  well  positioned  for  success,  Wendell  P.  Weeks,
president and chief  operating  officer,  will tell investors  today.  Weeks and
other  Corning  executives  will address an audience of more than 300  financial
analysts and investors at the company's annual investors  meeting beginning at 9
a.m. at the Mandarin Oriental Hotel in New York.

In an opening address to conference attendees,  James R. Houghton,  chairman and
chief  executive  officer,  will say,  "Corning is a unique  company...we  are a
company  devoted to creating  innovations  that are useful to society and become
successful  businesses for Corning." He will explain that Corning has repeatedly
brought forth  innovations  "that truly helped to change society,"  highlighting
Corning's  invention of the glass light bulb which led to the  commercialization
of electricity,  the creation of the color picture tube which revolutionized the
television  industry,  and optical  fiber  which has helped make the  internet a
reality.

Houghton also will reiterate his  announcement of Jan. 26 that he will turn over
the  role  of  chief  executive   officer  to  Weeks  at  the  company's  annual
shareholders'  meeting on April 28 and retain his  position  as  chairman of the
board  of  directors.   Peter  F.  Volanakis,   current   president  of  Corning
Technologies, will become chief operating officer.

Leadership Priorities
Weeks will tell investors, "Corning has a much stronger balance sheet today than
when we began our  restructuring  program in 2001. We have reduced the company's
overall  debt by more than $2 billion and improved  our  operating  cash flow to
over  $1  billion  last  year.  We have  seen a $1  billion  turn-around  in our
profitability  before special items over the past two years." This is a non-GAAP
financial measure. This and all non-GAAP financial measures disclosed during the
annual investors meeting are reconciled on the company's  investor relations Web
site and in attachments to this news release.

While addressing Corning's 2005 priorities, Weeks will say, "We must continue to
improve the company's overall  profitability,  generate positive free cash flow,
and manage our significant  capital spending  investments for future growth.  We
are  optimistic  that we will achieve an  investment  grade  credit  rating this
year." Weeks will also emphasize that this year is critical to Corning's  growth
businesses,  adding,  "We will learn a lot about how ambitious the regional bell
operating  companies will be with their fiber build outs,  engine  manufacturers
will announce their 2007 platform  choices for diesel  emissions  control and we
will see if  continued  retail  price  declines  spur  consumer  demand  for LCD
televisions."

Growth Opportunities
Telecommunications
Larry Aiello,  president and chief  executive  officer of Corning Cable Systems,
will tell  investors  that  while the  overall  telecommunications  industry  is
showing some signs of improvement,  there remains significant excess capacity in
the fiber and cable  industry.  "We are seeing public policy  improvements  that
encourage investment by telecommunications customers, while profitable broadband
service  models are emerging  among  providers,  and overall  network  demand is
increasing,"  he will say. "A sustainable  industry  recovery must ultimately be
led by  strong  customer  demand  for new  service  capabilities.  As  broadband
subscriber  growth  continues,  service and product  requirements will increase.
Optical  fiber is the gold  standard to deliver  these  end-user  requirements,"
Aiello will say. "For example, a broadband subscriber with fiber-to-the-premises
could  download the movie,  `The Matrix  Reloaded' in only 520 seconds,  while a
dial-up  telephone  connection  would tie up the line for 11 days.  And it would
take  almost two and half hours to download  this movie with a cable  modem," he
will state.

Corning will note that Verizon's FTTP project  successfully passed more than one
million  homes last year and they plan to add an  additional  two million  homes
this year.  Corning's total revenue  opportunity for each home passed is between
$130 and $220.  Additionally,  SBC and Bell South have begun fiber-based network
infrastructure  projects  which  may  provide  $35 to $55 per home in  potential
revenue opportunities for Corning.

Diesel Products
Volanakis  will tell  investors  that while the global diesel  product market is
about $200 million today,  growth will accelerate  strongly after 2006 driven by
U.S. regulatory  requirements and could reach a $1 billion market in 2008. "This
is a very important  year for us in the heavy duty diesel engine market.  Diesel
manufacturers will be making decisions for the 2007 vehicle engine platforms and
we believe we are  extremely  well  positioned  in this market.  We have already
received  several letters of intent from engine  manufacturers  and expect these
will lead to supply agreements this year," he will say.

Display Technologies
Corning  will tell  investors  that  overall  market  demand for liquid  crystal
display  (LCD) glass is  expected  to grow  between 40 percent and 60 percent in
2005 and continue to grow at a compound  annual rate of 40 percent through 2007.
"Corning's current view of this year's market growth is that it will be above 50
percent," Volanakis will say.

"The majority of the recent growth has been the result of LCD monitors replacing
the traditional desktop CRT and steady increases in notebook computers. However,
in 2005, LCD TV will continue its momentum, creating a third wave of glass
demand for our industry," Volanakis will say.

LCD TV's were 5 percent of all televisions sold in 2004 and the company believes
they will reach 10 percent market penetration in 2005. Corning will say that LCD
TV's may account for as much as 21 percent of the world's  television unit sales
by 2007.  LCD glass for TV,  currently at 75 million  square feet of demand will
grow to more than 500 million square feet in 2007. Volanakis will tell investors
that they  should  not focus on U.S.  LCD TV sales  alone in order to  determine
global market demand or trends.  More than 75 percent of the world's televisions
are sold outside of North America.

Regarding LCD glass price declines,  Volanakis will say, "Historically,  we have
seen a compound  annual rate of decline  near 5 percent.  We expect to see price
declines on LCD glass in this range during the first  quarter of this year after
two years of price stability. However, we anticipate that our continued focus on
manufacturing cost reduction will allow us to maintain our gross margins despite
expected price declines this year."

Financial Outlook
James B. Flaws, vice chairman and chief financial officer,  will tell attendees,
"Corning  has been on a journey  with three  phases.  We wanted to  improve  our
profitability  and  we  have  done  that.  We  have a goal  of  returning  to an
investment grade credit rating by 2005 and believe that we have made significant
progress  toward  that goal.  And,  we want to achieve  top  quartile  financial
performance by 2007."

He will tell investors that Corning  expects its capital  expenditures  to be in
the range of $1.2 billion to $1.4 billion in 2005, with approximately 75 percent
of this funding for LCD expansions.  The majority of the LCD capital spending is
for previously announced expansion projects. He will note that the company's LCD
expansions  are paced by the  industry's  growth  patterns and remain modular as
they can be adjusted according to actual market demand. Flaws will also say that
the company has a goal to achieve positive free cash flow again in 2005.

First-Quarter Outlook
Corning will also reaffirm its  first-quarter  guidance of sales in the range of
$980 million to $1.03 billion and earnings per share,  before special items,  in
the range of $0.11 to  $0.13.  This is a  non-GAAP  financial  measure.  Company
officials will tell investors they expect Corning's total LCD glass volume,  for
the combination of its wholly-owned business and 50 percent owned equity venture
Samsung Corning Precision Glass Co. Ltd., to increase sequentially for the first
quarter  in the range of 5 percent  to 10 percent  and LCD glass  pricing  could
decline by about 5 percent. Sequential optical fiber volume will be in the range
of flat to a 10  percent  decline  and  pricing  should  decline  by less than 5
percent. The company's sales of premium fiber will be less than 10 percent.

Conference Broadcast Information
Corning will make the presentation at its annual investor  conference  available

Presentation of Information in this News Release
Non-GAAP  financial  measures are not in accordance  with, or an alternative to,
GAAP.  Corning's  non-GAAP  net income and EPS measures  exclude  restructuring,
impairment  and  other  charges  and  adjustments  to prior  estimates  for such
charges.  Additionally,  the company's non-GAAP measures exclude  adjustments to
asbestos  settlement  reserves  required by movements in Corning's  common stock
price,  gains and  losses  arising  from debt  retirements,  charges  or credits
arising from adjustments to the valuation allowance against deferred tax assets,
equity method charges resulting from impairments of equity method investments or
restructuring, impairment or other charges taken by equity method companies, and
gains from discontinued operations. The company believes presenting non-GAAP net
income and EPS measures is helpful to analyze financial  performance without the
impact of unusual  items that may  obscure  trends in the  company's  underlying
performance. These non-GAAP measures are reconciled on the company's Web site at
www.corning.com/investor-relations and accompany this news release.

-------------------------------------------------------------------------------
Corning's comment, "We have a $1 billion turn-around in our profitability before
special items over the past two years." is a non-GAAP  financial  measure within
the meaning of Regulation G of the Securities and Exchange Commission.  Non-GAAP
financial  measures are not in accordance  with, or an alternative to, generally
accepted  accounting  principles  (GAAP).  The  company  believes  presenting  a
non-GAAP  improvement in net income is helpful to analyze financial  performance
without  the impact of unusual  items that may obscure  trends in the  company's
underlying  performance.  A detailed  reconciliation is provided below outlining
the  differences  between this  non-GAAP  measure and the directly  related GAAP
measure.

     www.corning.com/investor-relations  for an explanation of the special items
     being excluded.

2002 Special Items:

(b)  Corning  recorded  total  net  charges  of $2.08  billion  ($1.462  billion
     after-tax  and  minority  interest)  related to the  following  significant
     actions:  restructuring  charges of $1.271 billion ($929 million  after-tax
     and minority interest) for the closure of facilities,  workforce reductions
     and   abandonment  of  certain   construction   projects,   mostly  in  our
     Telecommunications  segment;  $400 million ($294 million after-tax) for the
     impairment of goodwill in our Telecommunications  segment; and $409 million
     ($239  million  after-tax)  for the  impairment  of assets of our  photonic
     technologies and conventional video components businesses.

(c)  During  2002,  Corning  retired a  significant  portion of  long-term  debt
     resulting in a gain of $176 million ($108 million after-tax).

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

(e)  On December 13, 2002,  Corning  completed  the sale of our  precision  lens
     business to 3M Company for approximately  $800 million in cash and recorded
     a gain on the sale of $652 million  ($415  million  after-tax)  included in
     income from discontinued operations. The remaining $63 million, net of tax,
     of  income  from  discontinued  operations  represents  the 2002  operating
     results of the precision lens business prior to the sale to 3M Company.

Corning's earnings per share (EPS) excluding special items for the first quarter
of 2005 is a non-GAAP  financial  measure  within the meaning of Regulation G of
the Securities and Exchange  Commission.  Non-GAAP financial measures are not in
accordance with, or an alternative to, generally accepted accounting  principles
(GAAP).  The  company  believes  presenting  non-GAAP  EPS is helpful to analyze
financial  performance  without  the  impact of unusual  items that may  obscure
trends in the company's  underlying  performance.  A detailed  reconciliation is
provided below outlining the differences  between this non-GAAP  measure and the
directly related GAAP measure.

Guidance: EPS excluding special items                   $0.11            $0.13

Special items:
     Restructuring, impairment and other 
       (charges) and credits (a)

     Asbestos settlement (b)

     (Loss) gain on repurchases and 
        retirements of debt, net (c)                    -----            -----

Earnings per share

        This schedule will be updated as additional announcements occur.

(a)  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.

(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.  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 first  quarter of 2005,  Corning will record a
     charge or credit for the change in its common  stock  price as of March 31,
     2005 compared to $11.77, the common stock price at December 31, 2004.

(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 first quarter 2005 guidance.

This schedule  contains  forward  looking  statements  within the meaning of the
Private  Securities   Litigation  Reform  Act  of  1995.  Such  forward  looking
statements  are based on current  expectations  and  involve  certain  risks and
uncertainties.  Actual  results may differ from those  projected  in the forward
