                     Corning Reports Fourth-Quarter Results


CORNING, N.Y. -- Corning Incorporated (NYSE:GLW) today reported a fourth-quarter
pro forma net loss of $261 million,  or $0.28 per share, down significantly from
pro forma earnings of $307 million,  or $0.33 per share,  for the fourth quarter
of 2000. The quarter results include pre-tax operating  charges,  announced last
week, totaling $178 million ($109 million after-tax), or $0.12 per share.

"Over  the  course  of the  second  half of  2001,  we took a  series  of  tough
restructuring  actions that improved our  competitive  position," John W. Loose,
Corning's  president and chief executive officer,  said. "We lowered inventories
significantly,  reduced  our  capital  expenditures,  resized  our  organization
through the  elimination  of 12,000  positions  and idled and closed a number of
manufacturing operations. We are focused on returning Corning to profitability,"
Loose said.

Fourth-quarter Operating Results
Fourth-quarter  sales  were $974  million,  less  than half of the $2.1  billion
reported in the  fourth-quarter of 2000. Sales and earnings declines were led by
the Telecommunications segment, which reported sales declines of 65% versus last
year and  operated  at a loss for the  quarter.  Optical  fiber and cable  sales
decreased  significantly  as demand for optical fiber was extremely  weak in the
quarter. This prompted significant  slowdowns in cable manufacturing  operations
and the  idling  of most of the  company's  fiber  manufacturing  facilities  in
November  and  December.  The company  announced  earlier  this month that it is
recalling  some  workers  to  resume  manufacturing   operations  in  its  fiber
production facilities beginning this week.

Weak global  economic  conditions  also  impacted  Corning's  other  businesses.
Fourth-quarter  sales and  earnings  of  Corning's  Advanced  Materials  segment
declined due  primarily  to weak sales in its  environmental  and  semiconductor
businesses.  The  Information  Display  segment  also  recorded  lower sales and
earnings in the fourth-quarter  driven primarily by weakness in its conventional
television business.

With these  fourth-quarter  results,  pro forma  earnings per share for the full
year were $0.17,  compared with $1.22 per share in 2000. Sales for the full year
totaled $6.3 billion, a decrease of 12% compared with $7.1 billion in 2000.

The  company  ended the year with $2.2  billion  in cash and  continues  to have
additional  liquidity with $2 billion of committed and unused  revolving  credit
lines.

Restructuring Actions
In the fourth quarter,  Corning  recorded a pre-tax charge of $614 million ($363
after-tax and minority  interest)  related to  restructuring  actions which were
part of the  previously  announced  program  totaling $961 million for the year.
Approximately  one third of the total  charges for the  program  will be paid in
cash.  Corning  expects  to  realize  annualized  savings  from the  program  of
approximately $400 million.

Fourth-Quarter and Calendar Year Results
With the  charges  for  restructuring  actions  and  amortization  of  goodwill,
Corning's  net loss  for the  quarter  was $655  million,  or $0.69  per  share,
compared  with a net loss of $58 million,  or $0.08 per share,  from  continuing
operations for the fourth quarter of 2000.

Including charges for restructuring  actions,  amortization of goodwill, and the
second-quarter  impairment of goodwill and intangible assets, Corning reported a
full-year 2001 loss of $5.5 billion, or $5.89 per share,  compared to net income
from continuing operations of $409 million, or $0.46 per share in 2000.

Outlook
James B. Flaws,  Corning's chief financial officer,  said, "While we continue to
experience weakness in demand across our telecommunications  businesses,  we are
beginning  to sense a settling in the market that  suggests we may see  improved
demand in the  second  half of this  year." He also  said the  company  will not
provide  guidance for its 2002  financial  performance at this time, but it will
discuss its  expectations  for the first quarter of 2002 at its investor meeting
on February 8, 2002 at the Plaza Hotel in New York City and  simultaneously  via
audio webcast.

"This past year was extremely challenging for everyone in the telecommunications
industry," Loose said. "At Corning, we believe in our optical layer strategy and
will continue to invest in and build a product and business portfolio which will
make us an even stronger player in the optical  networking  market.  We are also
excited  about a number  of  emerging  technologies  in our  Advanced  Materials
segment  and we believe  our liquid  crystal  display  business  is poised for a
strong year," Loose said.

Corning Incorporated and Subsidiary Companies
Notes to Consolidated Financial Statements
Quarter 4, 2001
(Unaudited; in millions, except per share amounts)

(1)  Information  by Operating  Segment  Information  about the  performance  of
     Corning's  three  operating  segments for the fourth quarter and year ended
     December  31, 2001 and 2000 are  presented  below.  These  amounts  exclude
     revenues,  expenses and equity  earnings not  specifically  identifiable to
     segments.  Segment  net income  excludes  impairment  and  amortization  of
     goodwill,   restructuring   actions,   purchased  in-process  research  and
     development costs, one-time acquisition costs and other nonrecurring items.
     This  measure  is not in  accordance  with  generally  accepted  accounting
     principles  (GAAP) and may not be  consistent  with  measures used by other
     companies.

     Corning prepared the financial results for its three operating  segments on
     a basis  that is  consistent  with the manner in which  Corning  management
     internally disaggregates financial information to assist in making internal
     operating  decisions.  Corning has  allocated  some common  expenses  among
     segments  differently  than it would for stand alone financial  information
     prepared in accordance with GAAP.  During the quarter ended March 31, 2001,
     Corning realigned one product line from the Advanced Materials segment into
     the  Telecommunications  segment.  Effective in the fourth quarter of 2001,
     and  as  reported  on  Form  8-K  filed  on  January  14,   2002,   Corning
     retroactively  revised  its segment  net income  definition  to include the
     amortization  of  intangible  assets.  Segment  results  for 2000 have been
     restated to conform to the current presentation.

(2)  Restructuring Actions
     During the fourth  quarter,  Corning  approved and began executing plans to
     close  additional  facilities  and downsize  its  workforce in an effort to
     reduce  capacity to meet future  expected  revenue  levels.  As a result of
     these  actions,  Corning  recorded a charge of $614 million  ($363  million
     after-tax and minority  interest) which includes a restructuring  charge of
     $308  million and a charge to impair plant and  equipment of $306  million.
     Corning has recorded  $961 million  ($590  million  after-tax  and minority
     interest) for restructuring actions in 2001.

     Restructuring Charges
     During the fourth quarter,  Corning recorded  restructuring charges of $308
     million.  The charge  includes  employee  separation  costs of $245 million
     (including curtailment losses related to pension and health care plans) and
     exit costs of $63  million  (principally  lease  termination  and  contract
     cancellation  payments).   The  plans  comprehend  the  elimination  of  an
     additional 4,000 positions  worldwide for a total of  approximately  12,000
     announced  in 2001.  Employees  have  been  informed  of the  restructuring
     initiatives and benefits  available to them under applicable  benefit plans
     or related  contractual  provisions.  These benefits include  voluntary and
     involuntary  separation,  early retirement and social programs.  During the
     fourth  quarter  Corning  paid  employee  related  separation  costs of $48
     million  and other exit  costs of $14  million.  For the full year  Corning
     recorded  charges of $324  million and $95 million and paid $60 million and
     $17 million  respectively,  for employee related separation and exit costs.
     As of December 31, 2001,  approximately  10,100 of the 12,000 employees had
     been separated under the plans.






     Impairment of Plant and Equipment
     Corning  recorded a fourth  quarter  charge of $306 million to impair plant
     and equipment  relating to facilities to be shutdown or disposed across all
     three operating  segments.  The impairment charges were determined based on
     the amount by which the  carrying  value  exceeded the fair market value of
     the asset. For the full year Corning recorded  impairment  charges totaling
     $542   million   related  to  plant  and   equipment,   primarily   in  the
     telecommunications operating segment.

     The charges relate to the operating segments as follows:



                                                                Restructuring Actions

(3)  Provisions for Inventory Write-Off
     During the second  quarter,  major  customers in the photonic  technologies
     business  reduced their order forecasts and canceled orders already placed.
     As a result, management determined that certain products were not likely to
     be sold in their  product  life cycle.  Corning  recorded a  provision  for
     excess and obsolete inventory, including estimated purchase commitments, of
     $273  million  ($184  million  after-tax)  in cost of sales  in the  second
     quarter of 2001.  In the fourth  quarter,  Corning  recorded an  additional
     provision of $60 million ($37 million after-tax) in cost of sales primarily
     for excess and obsolete inventory in the photonic  technologies business in
     response to continued weak demand.

(4)  Stock Compensation
     In the fourth quarter,  Corning's Board of Directors released  restrictions
     on 4.8  million  shares of  Corning  common  stock held by  employees.  The
     unamortized  expense  associated with the grants totaled $90 million.  This
     charge is included in selling, general and administrative expense.

(5)  Impairment of Goodwill and Other Intangible Assets
     During the first half of 2001, Corning  experienced a significant  decrease
     in the rate of growth of its telecommunications  segment,  primarily in the
     photonic technologies business, due to a dramatic decline in infrastructure
     spending in the  telecommunications  industry.  During the second  quarter,
     major customers in the photonic technologies business further reduced their
     order forecasts and canceled orders already placed.  Management  determined
     that the growth  prospects  of this  business are  significantly  less than
     previously expected and those of historical periods.

     As a result of these events and changes in circumstances,  Corning assessed
     the  recoverability  of certain  long-lived  assets related to the photonic
     technologies  business,  including  goodwill  and  other  intangibles,  and
     concluded that these assets were impaired.  Corning recorded a charge equal
     to the  difference  between  the  carrying  value  and fair  value of these
     assets.  Management's  estimate  of fair  value was based on  multiples  of
     forecasted   revenue  and  earnings  of  publicly  traded   companies  with
     operations in the optical component market segment.

     Corning  recorded  pre-tax  charges of $4.7 billion to impair a significant
     portion of the goodwill and approximately $100 million to impair intangible
     assets associated with certain business combinations  completed in 2000. Of
     the total charge of $4.8 billion,  $3.2 billion  related to the acquisition
     of the Pirelli  optical  components  business and $1.6  billion  related to
     goodwill resulting from the acquisition of NetOptix Corporation.






(6)  (Benefit) Provision for Income Taxes
     Corning's  tax rates  for the  fourth  quarter  and the full year 2001 were
     37.4% and 7.4%, respectively.  The full year rate is significantly impacted
     by  nondeductible  amortization  of goodwill  and other  one-time  charges.
     Excluding the impact of these items, the fourth quarter tax rate was 37.5%.
     The comparable rate for the fourth quarter 2000 was 32%. The fourth quarter
     of 2001 rate reflects certain one-time benefits attributable to the period.

(7)  Financing Transaction
     In November  2001,  Corning  completed a convertible  debt offering of $665
     million due November 1, 2008 and convertible into  approximately 69 million
     shares of common  stock.  Each $1,000  debenture was issued at par and pays
     interest  of 3.5%  semiannually.  The  proceeds  will be used  for  general
     corporate purposes.

(8)  Supplementary Cash Flow Data
     Supplemental disclosure of cash flow information is as follows:
