OVERVIEW



In response to the COVID-19 pandemic ("the pandemic") and the ensuing economic
uncertainty, including changing market conditions, the Company has and will
continue to focus on three core priorities: preserving the financial health of
the Company; protecting employees and communities; and delivering on customer
commitments.  We are continuing to build a stronger, more resilient company that
is committed to rewarding shareholders and supporting all global stakeholders.



Despite the pandemic and resulting global disruptions, Corning adapted rapidly
and remained resilient. We acted quickly to preserve our financial strength by
executing well and advancing major innovations with industry leaders. We have
continued to effectively leverage our focused and cohesive portfolio to create
value and outperform our underlying markets, contributing to sales and earnings
growth and strong free cash flow in the second half of 2020 and the first nine
months of 2021.



Corning announced the Strategy & Growth Framework in 2019, highlighting
significant opportunities to sell more Corning content through each of our
Market-Access Platforms.  The Company is focused on our cohesive portfolio and
the utilization of our financial strength, supported by strong operating cash
flow generation, which we expect to continue.  Corning has and will continue to
use its cash to grow, extend its leadership and reward shareholders.  Our key
growth drivers remain intact, and some are accelerating as key trends converge
around Corning's capabilities.



Corning will continue to advance the objectives of the Strategy & Growth
Framework, which sets its leadership priorities and articulates opportunities
across its businesses.  Our probability of success increases as we invest in our
world-class capabilities.  Corning is concentrating approximately 80% of its
research, development and engineering investment along with capital spending on
a cohesive set of three core technologies, four manufacturing and engineering
platforms, and five market-access platforms.  This strategy allows us to quickly
apply our talents and repurpose our assets across the company, as needed, to
capture high-return opportunities.

Summary of results for the three and nine months ended September 30, 2021





In the third quarter, net sales were $3,615 million, compared to $3,001 million
during the same period in 2020, a net increase of $614 million, or 20%.  Net
sales for the nine months ended September 30, 2021 were $10,406 million,
compared to $7,953 million during the same period in 2020, a net increase of
$2,453 million, or 31%, driven by increases in all segments.



In the third quarter of 2021, Corning generated net income of $371 million, or $0.43 per diluted share, compared to net income of $427 million, or $0.48 per diluted share, for the same period in 2020. The decrease in net income of $56 million was primarily driven by the following items (amounts presented after-tax):





?  The absence of an after-tax gain recorded on a previously held equity
   investment in HSG of $387 million.



The negative impacts to net income, outlined above, were partially offset by the following items:





?  Higher segment net income primarily driven by higher sales; net income
   increases by segment were $51 million, $24 million, $17 million and

$45 million for Display Technologies, Optical Communications, Life Sciences

and "All Other", respectively; ? Lower severance charges, impairment losses, capacity realignment and other

costs of $98 million; ? Translated earnings contract losses were $67 million lower than the third


   quarter of 2020; and
?  Equity in losses of affiliated companies were $66 million lower.




In the first nine months of 2021, Corning generated net income of $1,419 million, or $0.71 per diluted share, compared to net income of $260 million, or $0.24 per diluted share, for the same period in 2020. The increase in net income of $1,159 million and diluted earnings per share of $0.47, was primarily driven by the following items (amounts presented after-tax):

? Higher segment net income of $673 million primarily driven by higher sales;

net income increases by segment were

$208 million, $173 million, $111 million, $48 million, and $141 million for

Display Technologies, Optical Communications, Environmental Technologies,

Life Sciences and "All Other", respectively; ? The absence of after-tax asset impairment losses related to investments in

research and development programs within our All Other segment of $170

million;

? Lower severance charges, capacity realignment and other costs of $346

million;

? Translated earnings contract gains in the current period were $207 million

higher than prior year; ? The absence of a negative impact of a cumulative adjustment recorded during

the first quarter of 2020 to reduce revenue $105 million; and ? Higher translation gains of $137 million on Japanese yen-denominated debt.

The positive impacts to net income, outlined above, were partially offset by the following items:





?  The absence of an after-tax gain recorded on a previously held equity
   investment in HSG of $387 million.




The change in diluted earnings per share for the three months ended September
30, 2021, was primarily driven by changes in net income, outlined above.  The
change in diluted earnings per share for the nine months ended September 30,
2021, was primarily driven by the changes in net income, outlined above, as well
as the conversion of the Preferred Stock into 115 million Common Shares. The
immediate repurchase and retirement of 35 million Common Shares resulted in an
$803 million one-time reduction to net income available to common shareholders
during the second quarter of 2021.  Refer to Note 6 (Earnings per Common Share)
and Note 14 (Shareholders' Equity) to the consolidated financial statements for
additional information.



The translation impact of fluctuations in foreign currency exchange rates,
including the impact of hedges realized in the current quarter, adversely
impacted Corning's consolidated net income by $19 million and $20 million in the
three and nine months ended September 30, 2021, respectively, when compared to
the same periods in 2020.



2021 Corporate Outlook


We expect core net sales of approximately $3.5 to $3.7 billion for the fourth quarter of 2021.

the Display Technologies segment. (3) Amount represents the negative impact of a cumulative adjustment recorded

during the first quarter of 2020 to reduce revenue by $105 million. The

adjustment was associated with a previously recorded commercial benefit asset,

reflected as a prepayment, to a customer with a long-term supply agreement


    that substantially exited its production of LCD panels.

In the third quarter, net sales of reportable segments were $3,639 million, compared to $3,007 million during the same period in 2020, a net increase of $632 million, or 21%. Changes in net sales were as follows:

? Display Technologies' net sales increased by $129 million or 16%, largely due


   to volume growth of more than 10 percent and increased price in the
   low-single digits in percentage terms;

? Optical Communications' net sales increased by $222 million, or 24%, as sales


   volumes increased $179 million and $43 million for carrier products and
   enterprise products, respectively, primarily driven by 5G, broadband and
   cloud computing;

? Specialty Materials' net sales decreased by $14 million, or 2%, primarily due

to extremely strong demand for cover materials in support of customer product


   launches experienced during the third quarter of 2020;


?  Net sales for Environmental Technologies increased by $6 million, or 2%,

driven by higher diesel product sales, partially offset by lower automotive

product sales, which were significantly impacted by an industry-wide shortage


   of automotive components and semiconductor chips;


?  Net sales for Life Sciences increased by $82 million, or 37%, primarily
   driven by the ongoing recovery in academic and pharmaceutical research
   labs and continued strong demand for bioproduction vessels and

diagnostic-related consumables; and ? Net sales for "All Other" increased by $207 million, mainly driven by the


   consolidation of HSG, as of September 9, 2020.

In the nine months ended September 30, 2021, net sales of reportable segments
were $10,406 million, compared to $8,124 million during the same period in 2020,
a net increase of $2,282 million, or 28%.  Changes in net sales were as
follows:



? Display Technologies' net sales increased by $427 million or 18%, largely due

to mid-teens volume growth, in percentage terms, and consistent pricing;

? Optical Communications' net sales increased by $556 million, or 21%, as sales


   volumes increased $372 million and $184 million for carrier products and
   enterprise products, respectively, primarily driven by 5G, broadband and
   cloud computing;

? Specialty Materials' net sales increased by $151 million, or 11%, primarily


   driven by strong demand for premium cover materials, strength in the IT
   market, and greater optical content in semiconductor manufacturing;

? Net sales for Environmental Technologies increased by $308 million, or 33%,

primarily driven by improving markets and increased Corning content, along


   with strong demand for diesel products in China and North America;


?  Net sales for Life Sciences increased by $193 million, or 27%, primarily

driven by the ongoing recovery in academic and pharmaceutical research labs

and continued strong demand for bioproduction vessels and diagnostic-related

consumables; and ? Net sales for "All Other" increased by $647 million, mainly driven by the


   consolidation of HSG.




Movements in foreign exchange rates adversely impacted Corning's consolidated
net sales by $24 million and positively by $53 million, in the three and nine
months ended September 30, 2021, respectively, when compared to the same periods
in 2020.



Cost of Sales



The types of expenses included in the cost of sales line item are: raw materials
consumption, including direct and indirect materials; salaries, wages and
benefits; depreciation and amortization; production utilities;
production-related purchasing; warehousing (including receiving and inspection);
repairs and maintenance; inter-location inventory transfer costs; production and
warehousing facility property insurance; rent for production facilities; freight
and logistics costs; and other production overhead.



Gross Margin



In the three and nine months ended September 30, 2021, gross margin increased by
$320 million, or 32% and $1,474 million, or 64%, respectively. Gross margin as a
percentage of sales increased by 4 percentage points and 7 percentage points,
respectively. The increase in gross margin was primarily driven by higher sales,
as well as lower charges for restructuring and capacity realignment of $124
million and $383 million, respectively. These increases were partially offset by
increased expenses due to elevated freight and logistics costs, as well as
higher inflation.



The translation impact of fluctuations in foreign currency exchange rates,
including the impact of hedges realized in the current quarter, adversely
impacted Corning's consolidated gross margin by $42 million and $40 million in
the three and nine months ended September 30, 2021, respectively, when compared
to the same periods in 2020.


Selling, General and Administrative Expenses





In the three and nine months ended September 30, 2021, selling, general and
administrative expenses increased by $6 million, or 1%, and $75 million, or 6%,
respectively, and declined by 3 percentage points as a percentage of sales, when
compared to the prior periods.  Increases in these costs were primarily driven
by higher compensation and benefit expenses and the consolidation of HSG,
partially offset by lower restructuring and other charges and credits of $21
million and $91 million, respectively, when compared to the same periods in
2020.



The types of expenses included in the selling, general and administrative
expenses line item are: salaries, wages and benefits; share-based compensation
expense; travel; sales commissions; professional fees; and depreciation and
amortization, utilities, rent for administrative facilities and restructuring,
impairment and other charges and credits.

Research, Development and Engineering Expenses





In the three and nine months ended September 30, 2021, research, development and
engineering expenses increased by $20 million, or 9%, and
decreased $207 million, or 22%, respectively, when compared to the same periods
last year.  The primary driver was lower restructuring, impairment, and other
charges and credits of $18 million and $243 million, respectively.  As a
percentage of sales, these expenses were 1 and 5 percentage points lower,
respectively, for the three and nine months ended September 30, 2021, when
compared to the same periods last year.



Translated earnings contract (loss) gain, net





Included in the line item translated earnings contract (loss) gain, net, is the
impact of foreign currency hedges which hedge translation exposure arising from
movements in the Japanese yen, South Korean won, new Taiwan dollar, euro,
Chinese yuan and British pound and its impact on net income. The following table
provides detailed information on the impact of translated earnings contract
gains and losses:

Income Before Income Taxes


The translation impact of fluctuations in foreign currency exchange rates, including the impact of hedges realized in the current quarter, adversely impacted Corning's consolidated income before income taxes by $23 million and $25 million for the three and nine months ended September 30, 2021, respectively, when compared to the same periods in 2020.

For the three months ended September 30, 2021, the effective income tax rate
differed from the U.S. statutory rate of 21%, primarily due to non-deductible
expenses for tax purposes, foreign rate differential, and tax reform items. 

For


the nine months ended September 30, 2021, the effective income tax rate differed
from the U.S. statutory rate of 21% primarily due to an adjustment to the
permanently reinvested foreign income position, excess tax benefit related to
share-based compensation payments, foreign rate differential, and tax reform
items related to The Tax Cuts and Jobs Act of 2017.



For the three and nine months ended September 30, 2020, the effective income tax
rate differed from the U.S. statutory rate of 21%, primarily due to an estimate
of income tax benefits generated by a current year net operating loss that will
be carried-back to prior years as allowed under the CARES Act and changes of
estimates based on the final 2019 U.S. tax return which were partially offset by
additional income tax reserves.  For the nine months ended September 30, 2020,
the effective income tax rate differed from the U.S. statutory rate of 21%
primarily due to an estimate of income tax benefits generated by a current year
net operating loss that will be carried-back to prior years as allowed under the
CARES Act and changes of estimates based on the final 2019 U.S. tax return which
were partially offset by income tax reserves, an adjustment to the permanently
reinvested foreign income position and foreign valuation allowances on deferred
tax assets.

    statements for additional information.




Comprehensive Income



For the three months ended September 30, 2021, comprehensive income decreased by
$561 million when compared to the same period in 2020, primarily due to a
decline in net income of $56 million and a net loss on foreign currency
translation adjustments of $475 million, largely driven by the Japanese yen,
South Korean won and euro.



For the nine months ended September 30, 2021, comprehensive income increased by
$603 million when compared to the same period in 2020, primarily due to an
increase in net income of $1,159 million.  The increase in comprehensive income
was partially offset by the net loss on foreign currency translation adjustments
of $591 million, primarily driven by the Japanese yen, South Korean won, and
euro.

CORE PERFORMANCE MEASURES



In managing the Company and assessing our financial performance, certain
measures provided by our consolidated financial statements are adjusted to
exclude specific items to arrive at core performance measures. These items
include gains and losses on translated earnings contracts, acquisition-related
costs, certain discrete tax items and other tax-related adjustments,
restructuring, impairment losses, and other charges and credits, certain
litigation-related expenses, pension mark-to-market adjustments and other items
which do not reflect on-going operating results of the Company or our equity
affiliates. Corning utilizes constant-currency reporting for our Display
Technologies, Environmental Technologies, Specialty Materials and Life Sciences
segments for the Japanese yen, South Korean won, Chinese yuan, new Taiwan dollar
and the euro. The Company believes that the use of constant-currency reporting
allows investors to understand our results without the volatility of currency
fluctuations and reflects the underlying economics of the translated earnings
contracts used to mitigate the impact of changes in currency exchange rates on
earnings and cash flows. Corning also believes that reporting core performance
measures provides investors greater transparency to the information used by the
management team to make financial and operational decisions.



Core performance measures are not prepared in accordance with GAAP. We believe
investors should consider these non-GAAP measures in evaluating results as they
are more indicative of our core operating performance and how management
evaluates operational results and trends. These measures are not, and should
not, be viewed as a substitute for GAAP reporting measures. With respect to the
Company's outlook for future periods, it is not possible to provide
reconciliations for these non-GAAP measures because the Company does not
forecast the movement of foreign currencies against the U.S. dollar, or other
items that do not reflect ongoing operations, nor does it forecast items that
have not yet occurred or are out of the Company's control. As a result, the
Company is unable to provide outlook information on a GAAP basis.



For a reconciliation of non-GAAP performance measures to their most directly comparable GAAP financial measure, please see "Reconciliation of Non-GAAP Measures".

Core Net Income



In the three months ended September 30, 2021, we generated core net income of
$485 million, or $0.56 per diluted share, compared to core net income generated
in the three months ended September 30, 2020 of $380 million, or $0.43 per
diluted share.  The increase of $105 million, or $0.13 per diluted share, was
primarily due to higher segment net income when compared to the same period in
2020. Net income increases by reportable segment are as follows:



? Display Technologies' net income increased by $51 million, primarily driven

by increased volume;

? Optical Communications' net income increased by $24 million, largely driven

by volume, partially offset by increased raw material and shipping costs; and




?  Life Sciences' and "All Other" net income increased by $17 million, and
   $45 million, respectively.



The increases to segment net income were partially offset by income declines of $39 million and $9 million for Specialty Materials and Environmental Technologies, respectively. The change in diluted earnings per share was primarily driven by changes in net income.





In the nine months ended September 30, 2021, we generated core net income of
$1,346 million, or $1.53 per diluted share, compared to core net income
generated in the nine months ended September 30, 2020 of $775 million, or
$0.88 per diluted share.  The increase of $571 million, and $0.65 per diluted
share, was primarily due to higher earnings across most operating segments when
compared to the same period in 2020. Net income changes by reportable
segment are as follows:



? Display Technologies' net income increased by $208 million, primarily driven

by increased volume;

? Optical Communications' net income increased by $173 million, largely driven


   by volume, partially offset by increased raw material and shipping costs;
?  Specialty Materials' net income decreased by $8 million;


?  Environmental Technologies' net income increased by $111 million; and
?  Life Sciences' and "All Other" net income increased by $48 million and
   $141 million, respectively.

Reconciliation of Non-GAAP Measures

Corning utilizes certain financial measures and key performance indicators that
are not calculated in accordance with GAAP to assess financial and operating
performance. A non-GAAP financial measure is defined as a numerical measure of a
company's financial performance that (i) excludes amounts, or is subject to
adjustments that have the effect of excluding amounts, that are included in the
comparable measure calculated and presented in accordance with GAAP in the
consolidated statements of income or statements of cash flows, or (ii) includes
amounts, or is subject to adjustments that have the effect of including amounts,
that are excluded from the comparable measure as calculated and presented in
accordance with GAAP in the consolidated statements of income or statements of
cash flows.



Core net sales, core equity in earnings of affiliated companies and core net
income are non-GAAP financial measures utilized by management to analyze
financial performance without the impact of items that are driven by general
economic conditions and events that do not reflect the underlying fundamentals
and trends in the Company's operations.

Shares. Corning immediately repurchased 35 million of the converted Common

Shares and excluded them from the weighted-average common shares outstanding

for the calculation of the Company's basic and diluted earnings per share. The


    redemption of these Common Shares resulted in an $803 million reduction of
    retained earnings which reduced the net income available to common
    shareholders.

Table of Contents

Items which we exclude from GAAP measures to arrive at core performance measures are as follows:

(1) Constant-currency adjustment: Because a significant portion of segment revenues and

expenses are denominated in currencies other than the U.S. dollar, management believes it

is important to understand the impact on core net income of translating these currencies

into U.S. dollars. Display Technologies' segment sales and net income are primarily

denominated in Japanese yen, but also impacted by the South Korean won, Chinese yuan, and

new Taiwan dollar. Environmental Technologies and Life Science segments sales and net

income are primarily impacted by the euro and Chinese yuan. Presenting results on a

constant-currency basis mitigates the translation impact and allows management to evaluate

performance period over period, analyze underlying trends in the businesses, and establish

operational goals and forecasts. We establish constant-currency rates based on internally

derived management estimates which are closely aligned with the currencies we have hedged.

Constant-currency rates are as follows:


       Currency     Japanese yen    Korean won    Chinese yuan    New Taiwan dollar       Euro
         Rate           ¥107          ?1,175          ¥6.7              NT$31             €.81

(2) Translation (gain) loss on Japanese yen-denominated debt: We have excluded the gain or loss

on the translation of the yen-denominated debt to U.S. dollars. (3) Translated earnings contract (loss) gain: We have excluded the impact of the realized and

unrealized gains and losses of the Japanese yen, South Korean won, Chinese yuan, euro and

new Taiwan dollar-denominated foreign currency hedges related to translated earnings, as

well as the unrealized gains and losses of the British pound-denominated foreign currency

hedges related to translated earnings. (4) Acquisition-related costs: These expenses include intangible amortization, inventory

valuation adjustments, external acquisition-related deal costs, and other transaction

related costs. (5) Discrete tax items and other tax-related adjustments: These include discrete period tax

items such as changes of tax reserves and changes in our permanently reinvested foreign

income position. (6) Pension mark-to-market adjustment: Defined benefit pension mark-to-market gains and losses,

which arise from changes in actuarial assumptions and the difference between actual and

expected returns on plan assets and discount rates. (7) Restructuring, impairment and other charges and credits: This amount includes

restructuring, impairment losses and other charges and credits, primarily accelerated

depreciation and asset write-offs, which are not related to continuing operations and are

not classified as restructuring expense. During the third quarter of 2021, we recorded

asset write-offs and charges related to facility repairs resulting from the impact of power

outages. The Company is pursuing recoveries under its applicable property insurance

policies.

(8) Litigation, regulatory and other legal matters: Includes amounts that reflect developments

in commercial litigation, intellectual property disputes, adjustments to the estimated

liability for environmental-related items and other legal matters. (9) Preferred stock conversion: This amount includes the put option from the Share Repurchase


      Agreement with Samsung Display Co., Ltd.
(10)  Bond redemption loss: Amount represents premiums on redemption of debentures
(11)  Loss on investments: Amount represents the loss recognized due to mark-to-mark adjustments

capturing the change in fair value based on the closing stock market price. (12) Gain on sale of business: Amount represents the gain recognized for the sale of certain

businesses.

(13) Equity in losses of affiliated companies: These adjustments relate to costs not related to

continuing operations of our affiliated companies, such as restructuring, impairment

losses, inventory adjustments, other charges and credits and settlements under

"take-or-pay" contracts, including Corning's share of HSG's settlement of its pre-existing

relationship of its long-term supply contract related to the HSG's acquisition of TCS. (14) Transaction-related gain, net: Amount represents the pre-tax gain recorded on a previously

held equity investment in HSG. (15) Cumulative adjustment related to customer contract: The negative impact of a cumulative

adjustment recorded during the first quarter of 2020 to reduce revenue by $105 million. The

adjustment was associated with a previously recorded commercial benefit asset, reflected as

a prepayment, to a customer with a long-term supply agreement that substantially exited its


      production of LCD panels.

All other businesses that do not meet the quantitative threshold for separate
reporting have been grouped as "All Other." This group is primarily comprised of
the results of the pharmaceutical technologies, auto glass, new product lines,
development projects, and certain corporate investments.



The Company obtained a controlling interest in HSG during the third quarter of
2020 and has consolidated results in "All Other" as of September 9, 2020.  Refer
to Note 3 (HSG Transactions) to the consolidated financial statements for
additional information on this transaction.



Financial results for the reportable segments are prepared on a basis consistent
with the internal disaggregation of financial information to assist the CODM in
making internal operating decisions. A significant portion of segment revenues
and expenses are denominated in currencies other than the U.S. dollar.
Management believes it is important to understand the impact on core net income
of translating these currencies into U.S. dollars. The Company uses constant
currency reporting for Display Technologies, Specialty Materials, Environmental
Technologies and Life Sciences.  Corning excludes the impact of these currencies
from segment sales and net income.  The adjustment for constant currency is
primarily related to the Display Technologies' segment and excludes the impact
of the fluctuation of the Japanese yen, South Korean won, Chinese yuan, and new
Taiwan dollar.  Certain income and expenses are included in the unallocated
amounts in the reconciliation of reportable segment net income (loss) to
consolidated net income. These include items that are not used by the CODM in
evaluating the results of or in allocating resources to the segments and include
the following items: the impact of translated earnings contracts;
acquisition-related costs; discrete tax items and other tax-related adjustments;
certain litigation, regulatory and other legal matters; restructuring,
impairment losses and other charges and credits; adjustments relating to
acquisitions; and other non-recurring non-operational items. Although these
amounts are excluded from segment results, they are included in reported
consolidated results.



Earnings of equity affiliates that are closely associated with the reportable
segments are included in the respective segment's net income (loss). Certain
common expenses among reportable segments have been allocated differently than
they would for stand-alone financial information. Segment net income (loss) may
not be consistent with measures used by other companies.

Net sales in the Specialty Materials segment declined by $14 million and
increased $151 million, respectively, for the three and nine months ended
September 30, 2021.  Net sales declined slightly for the three months ended
September 30, 2021, primarily due to extremely strong demand for cover materials
in support of customer product launches experienced during the third quarter of
2020.  Strong demand for premium cover materials, strength in the IT market and
greater optical content in semiconductor manufacturing were the primary drivers
of the increase for the nine months ended September 30, 2021.



Net income decreased by $39 million and $8 million, respectively, for the three
and nine months ended September 30, 2021, primarily driven by increased
investments in innovation programs that are moving towards commercialization and
higher inflationary and logistics costs.

Management Assessment of Liquidity

Corning is committed to strong financial stewardship and expects to maintain a strong cash balance and generate positive free cash flow for the year.





We ended the third quarter of 2021 with approximately $2.2 billion of cash and
cash equivalents. Our cash and cash equivalents are held in various locations
throughout the world and are generally unrestricted.  We utilize a variety of
strategies to ensure that our worldwide cash is available in the locations in
which it is needed.  At September 30, 2021, approximately 74% of the
consolidated amount was held outside the U.S.



Corning has a commercial paper program pursuant to which we may issue
short-term, unsecured commercial paper notes up to a maximum aggregate principal
amount outstanding at any one time of $1.5 billion. Under this program, the
Company may issue the paper from time to time and will use the proceeds for
general corporate purposes. As of September 30, 2021, Corning had no outstanding
commercial paper.


The Company's $1.5 billion Revolving Credit Agreement is available to support its commercial paper program, if needed, and for general corporate purposes.





Other



Comprehensive reviews of significant customers and their creditworthiness are
completed by analyzing their financial strength, at least annually or more
frequently, for customers where Corning has identified an increased measure of
risk.  The Company closely monitors payments and developments which may signal
possible customer credit issues.  During the three months ended September 30,
2021, Corning sold accounts receivable and accelerated collections for the
period by $80 million. Sales of accounts receivable during the first and second
quarter of 2021, were $133 million and $192 million, respectively, which the
Company believes would have been collected during the normal course of business
in the quarter following the respective sales.  Corning has not currently
identified any potential material impact on our liquidity resulting from
customer credit issues.

Table of Contents

We believe we have sufficient liquidity to fund operations, acquisitions, capital expenditures, scheduled debt repayments and dividend payments





The Revolving Credit Agreement includes affirmative and negative covenants with
which we must comply, including a leverage (debt to capital ratio) financial
covenant. The required leverage ratio is a maximum of 60%. At September 30,
2021, the leverage using this measure was approximately 36%. As of September 30,
2021, we were in compliance and no amounts were outstanding under the Company's
Revolving Credit Agreement.



The Company's debt instruments contain customary event of default provisions,
which allow the lenders the option of accelerating all obligations upon the
occurrence of certain events. In addition, some of the debt instruments contain
a cross default provision, whereby an uncured default of a specified amount on
one debt obligation of the Company, would be considered a default under the
terms of another debt instrument. As of September 30, 2021, we were in
compliance with all such provisions.



Other than discussed, management is not aware of any known trends or any known
demands, commitments, events or uncertainties that will, or are reasonably
likely to, result in insufficient liquidity. There are no known trends,
favorable or unfavorable, that would have a material change in the overall cost
of liquidity.


Off Balance Sheet Arrangements

There have been no material changes outside the ordinary course of business in off balance sheet arrangements as disclosed in the 2020 Form 10-K under the caption "Off Balance Sheet Arrangements."





Contractual Obligations



There have been no material changes outside the ordinary course of business in

The preparation of financial statements requires management to make estimates
and assumptions that affect amounts reported therein. The estimates that require
management's most difficult, subjective or complex judgments are described in
the 2020 Form 10-K and remain unchanged through the first nine months of 2021.
For certain items, additional details are provided below.



Impairment of Assets Held for Use





We are required to assess the recoverability of the carrying value of long-lived
assets when an indicator of impairment has been identified. We review long-lived
assets in each quarter in which impairment indicators are present. We must
exercise judgment in assessing whether an event of impairment has occurred.



Manufacturing equipment includes certain components of production equipment that
are constructed of precious metals, primarily platinum and rhodium. These metals
are not depreciated because they have very low physical losses and are
repeatedly reclaimed and reused in the manufacturing process and have a very
long useful life. Precious metals are reviewed for impairment as part of the
assessment of long-lived assets. This review considers all the Company's
precious metals that are either in place in the production process; in
reclamation, fabrication, or refinement in anticipation of re-use; or awaiting
use to support increased capacity. Precious metals are acquired to support the
manufacturing operations and are not held for trading or other purposes.



At September 30, 2021 and December 31, 2020, the carrying value of precious
metals was $3.3 billion and $3.4 billion, respectively, and significantly lower
than the fair market value.  Most of these precious metals are utilized by the
Display Technologies and Specialty Materials segments.  The potential for
impairment exists in the future if negative events significantly decrease the
cash flow of these segments.  Such events include, but are not limited to, a
significant decrease in demand for products or a significant decrease in
profitability in these segments.

NEW ACCOUNTING STANDARDS


Refer to Note 1 (Significant Accounting Policies) to the consolidated financial statements.







ENVIRONMENT



Corning has been named by the Environmental Protection Agency (the Agency) under
the Superfund Act, or by state governments under similar state laws, as a
potentially responsible party for 15 active hazardous waste sites.  Under the
Superfund Act, all parties who may have contributed any waste to a hazardous
waste site, identified by the Agency, are jointly and severally liable for the
cost of cleanup unless the Agency agrees otherwise.  It is Corning's policy to
accrue for its estimated liability related to Superfund sites and other
environmental liabilities related to property owned by Corning based on expert
analysis and continual monitoring by both internal and external consultants.  At
September 30, 2021 and December 31, 2020, Corning had accrued approximately $60
million and $68 million, respectively, for the estimated undiscounted liability
for environmental cleanup and related litigation. Based upon the information
developed to date, management believes that the accrued reserve is a reasonable
estimate of the Company's liability and that the risk of an additional loss in
an amount materially higher than that accrued is remote.

FORWARD-LOOKING STATEMENTS



The statements in this Quarterly Report on Form 10-Q, in reports subsequently
filed by Corning with the SEC on Forms 8-K, and related comments by management
that are not historical facts or information and contain words such as "will,"
"believe," "anticipate," "expect," "intend," "plan," "seek," "see," "would," and
"target" and similar expressions are forward-looking statements. Such statements
relate to future events that by their nature address matters that are, to
different degrees, uncertain. These forward-looking statements relate to, among
other things, the Company's future operating performance, the Company's share of
new and existing markets, the Company's revenue and earnings growth rates, the
Company's ability to innovate and commercialize new products, and the Company's
implementation of cost-reduction initiatives and measures to improve pricing,
including the optimization of the Company's manufacturing capacity.



Although the Company believes that these forward-looking statements are based
upon reasonable assumptions regarding, among other things, current estimates and
forecasts, general economic conditions, its knowledge of its business, and key
performance indicators that impact the Company, actual results could differ
materially. The Company does not undertake to update forward-looking statements.
Some of the risks, uncertainties and other factors that could cause actual
results to differ materially from those expressed in or implied by the
forward-looking statements include, but are not limited to:



- the duration and severity of the COVID-19 pandemic, and its impact across our

businesses on demand, operations, our global supply chains and stock price; - the effects of acquisitions, dispositions and other similar transactions; - global economic trends, competition and geopolitical risks, or an escalation

of sanctions, tariffs or other trade tensions between the U.S. and China or

other countries, and related impacts on our businesses' global supply chains

level or to repurchase shares at planned levels; - possible disruption in commercial activities or our supply chain due to

terrorist activity, cyber-attack, armed conflict, political or financial

instability, natural disasters, international trade disputes or major health

concerns;

  information technology infrastructure;
- unanticipated disruption to our supply chain, equipment, facilities, IT
  systems or operations;
