2019 January Introduced the industry’s first AutoGrade™ Corning Gorilla Glass solutions 2019 Financial Performance Before I delve into our strategy, I’d like to share Corning’s financial results from last year. Our core sales were $11.7 billion, up 2% from 2018, driven by growth in Environmental Technologies, Specialty Materials, and Life Sciences. Core earnings per share were $1.76. During 2019, we set new four-year targets for growth and capital allocation, we increased our dividend, and we demonstrated our ability to generate significant operating cash flow even with market performance below our expectations. Strong capital stewardship is a cornerstone of our management approach. Once again, we outperformed our underlying markets in each business segment. We grew Environmental Technologies sales 16% against a backdrop of declining car sales. We grew Specialty Materials sales 8% while smartphone units were down. In Life Sciences, we exceeded industry growth rates on the strength of new bioprocess and advanced cell culture products. In Display Technologies, our glass volume grew at a mid-single digit rate even though TV unit sales were down.

See “Items Excluded from GAAP Measures” below for the descriptions of the footnoted reconciling items. 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. Our 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. Beginning January 1, 2019, as our Environmental Technologies and Life Science segments sales and net income are impacted by the euro, Chinese yuan and Japanese yen, these segments will also be presented on a constant-currency basis. We have not recast the prior periods for these two segments as the impact of fluctuations in these currencies are not material for prior periods. Presenting results on a constant-currency basis mitigates the translation impact and allows management to evaluate performance period over period, analyze underlying trends in our 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 our yen-denominated debt to U.S. dollars. (3) Translated earnings contract (gain) loss: We have excluded the impact of the realized and unrealized gains and losses of our Japanese yen, South Korean won, Chinese yuan and new Taiwan dollar-denominated foreign currency hedges related to translated earnings, as well as the unrealized gains and losses of our euro and British pound-denominated foreign currency hedges related to translated earnings. (4) Acquisition-related costs: These expenses include intangible amortization, inventory valuation adjustments and external acquisition-related deal costs. CORNING 2019 ANNUAL REPORT (5) Discrete tax items and other tax-related adjustments: For 2019, these include discrete period tax items such as changes in tax law, the impact of tax audits, changes in judgement about the realizability of certain deferred tax assets and other tax-related adjustments. For 2018, this amount primarily relates to the preliminary IRS audit settlement offset by changes in judgment about the realizability of certain deferred tax assets. For 2017, this amount represents the removal of discrete adjustments (e.g., changes in tax law, other than those of the 2017 Tax Act which are set forth separately, and changes in judgment about the realizability of certain deferred tax assets) as well as other non-operational tax-related adjustments. (6) Litigation, regulatory and other legal matters: Includes amounts that reflect developments in commercial litigation, intellectual property disputes, adjustments to our estimated liability for environmental-related items and other legal matters. (7) Restructuring, impairment and other charges or credits: This amount includes restructuring, impairment and other charges or credits, as well as other expenses, primarily accelerated depreciation and asset write-offs, which are not related to continuing operations and are not classified as restructuring expense. 24

Page 35

Management’s Discussion and Analysis of Financial Condition and Results of Operations (8) Equity in (earnings) losses of affiliated companies: These adjustments relate to costs not related to continuing operations of our affiliated companies, such as restructuring, impairment and other charges and settlements, or modifications, under “take-or-pay” contracts. (9) Adjustments related to acquisitions: Includes fair value adjustments to the Corning Precision Materials (“CPM”) indemnity asset related to contingent consideration, post-combination expenses and other acquisition and disposal adjustments. (10) 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. (11) Adjustments resulting from the 2017 Tax Act: Includes a provisional amount related to the one-time mandatory tax on unrepatriated foreign earnings, a provisional amount related to the remeasurement of U.S. deferred tax assets and liabilities, changes in valuation allowances resulting from the 2017 Tax Act, and adjustments for the elimination of excess foreign tax credit planning.

Corning’s glass volume increased by a mid-single digit percentage, a mid-single digit percentage, similar to the mid-single digit percentage higher than the overall market, driven by increased Gen 10.5 output growth expected in the display glass market.

Net income in the Display Technologies segment decreased by $49 million in the year ended December 31, 2019, driven by the decrease in sales outlined above. Display Technologies shipped more glass in the first half of 2019 than in the latter half. Due to lower glass volumes in the second half of 2019, factory utilization declined impacting profitability. 25
