Dear Fellow Shareholder:

Corning Incorporated will hold its 2020 Annual Meeting in Corning, New York, on April 30 at 11 a.m. Eastern Time. Shareholders will vote on the annual election of directors, the advisory approval of the 2019 compensation for our named executive officers, and the ratification of Corning's independent registered public accounting firm for 2020.

This meeting is your opportunity to hear directly from leadership about Corning's 2019 performance and our expectations for the future. We're pleased that we successfully delivered on the goals of our four-year Strategy and Capital Allocation Framework, returning more than $12.5 billion to shareholders over four years, including a 67% increase in dividends per share. We also extended our leadership in every business, advanced key growth initiatives, and positioned the company to drive long-term growth.

In 2019, we announced our new Strategy & Growth Framework, which defines our leadership priorities through 2023 and reflects our core leadership philosophy of operating our businesses well, investing to capture profitable growth opportunities that align with our focused portfolio, de-risking investments through customer commitments, and distributing cash to shareholders. It's our previous Framework evolved for a new growth era.

Of course, how we do things is as important as what we achieve. We are committed to making the world a better place, not only with our innovations, but also with our actions.

We practice sound corporate governance and align our practices with the principles of the Investor Stewardship Group. We communicate consistently and openly with our shareholders. We have improved our disclosure around all our practices and policies. And we follow industry best practices on executive pay, including tying compensation closely to company performance.

I'm also proud of how we continue to honor our commitment to sustainability. Corning is helping protect the environment through the ongoing improvement of processes, products, and services. We are committed to ensuring a diverse and inclusive environment for our employees around the world. And Corning invests to strengthen the economy and enhance the quality of life in the communities where we live and work. We understand that our sustainability efforts are a work in progress, so we look forward to evolving our practices to continue making Corning a better version of itself.

I look forward to sharing more details at the Annual Meeting. The following pages contain the formal notice of meeting and the proxy statement. I encourage you to sign and return your proxy card or vote by telephone or Internet prior to April 30 so your shares will be represented and voted at the meeting.

CORE PERFORMANCE MEASURES

In managing the Company and assessing our financial performance, we adjust certain measures in our consolidated financial statements to arrive at measures that are not calculated in accordance with GAAP and exclude specific items that are non-recurring, related to foreign exchange volatility, or unrelated to continuing operations. These measures are our Core Performance Measures. Our management uses Core Performance Measures to make financial and operational decisions. We believe that sharing our Core Performance Measures with investors provides greater visibility into how we make business decisions. Accordingly, these measures also form the basis for our compensation program metrics.

Items that are excluded from certain Core Performance calculations include: gains and losses on our translated earnings contracts, acquisition-related costs, certain discrete tax items and other tax-related adjustments, restructuring, impairment, and other charges or credits, certain litigation-related expenses, pension mark-to-market adjustments and other items which do not reflect on-going operating results of the Company. More information on these items can be found in Appendix A.

Corning utilizes constant-currency reporting for our Display Technologies and Specialty Materials segments for the Japanese yen, South Korean won, Chinese yuan and new Taiwan dollar currencies. Effective January 1, 2019, Corning also began using constant-currency reporting for our Environmental Technologies and Life Sciences segments for the euro, Japanese yen and Chinese yuan. The Company believes that the use of constant-currencyreporting 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 our earnings and cash flows. We have hedged approximately 91% of our projected yen exposure through 2022.

These non-GAAP measures are not an alternative, or a replacement, for financial results determined in accordance with generally accepted accounting principles. Please see Appendix A to this proxy statement for a reconciliation of the non-GAAPmeasures we use in this proxy statement to the most directly comparable GAAP financial measures.

Proxy Statement Summary

Successful Completion of our 2016-2019 Strategy and Capital Allocation Framework

In 2019, Corning successfully delivered the goals under its 2016-2019 Strategy and Capital Allocation Framework. Using the framework, we focused our portfolio through disciplined project selection and the strategic realignment of Dow Corning. We invested more than $10 billion to grow and extend our leadership through significant new products, capacity expansion and strategic acquisitions. Corning returned more than $12.5 billion to shareholders; increased dividends per share 67%; and reduced outstanding shares by more than 37%. We also created value for our shareholders: Corning's total shareholder return (TSR) from the inception of the framework through its completion was 93.26%, well above the S&P 500 TSR of 74.23% during the same period.

Our opportunities and execution allowed us to increase both our investments and shareholder returns beyond our initial targets. Our successful execution positions us to deliver growth far into the future.

2019 Performance Highlights

While we successfully delivered the goals of the Strategy and Capital Allocation Framework, 2019 presented challenges that negatively affected our 2019 financial performance, executive compensation, and total shareholder return. Our 2019 growth did not meet our targets and we accelerated actions in our Optical Communications and Display Technologies segments to align production output and working capital to current customer demand, which impacted gross margin. Despite these challenges, we once again outperformed our underlying markets. We expect to build momentum throughout 2020 that will keep us on track to achieve the goals set forth in our four-year Strategy & Growth Framework.

In 2019:

• Corning grew sales 2% driven by strong performance in three segments and outperformed underlying markets
• Environmental Technologies grew sales 16% in an auto market that was down mid-single digits, driven by the adoption of Corning's proprietary gasoline particulate filter (GPF) innovation
• Specialty Materials grew sales 8% with the adoption of industry-leading cover glass innovations despite smartphone unit sales being down 3%
• Life Sciences reached a $1 billion sales milestone, growing more than twice the rate of a strengthening market
• Corning's Display glass pricing reached low-single digit percentage declines for the year
• Corning significantly advanced product commercialization in Corning Valor® Glass, with FDA approval and supply agreements, and in Automotive Glass Solutions, with the opening of a dedicated factory to support growing demand from industry leaders
• We advanced key growth initiatives and took actions to address the material impact of changing market and customer dynamics in Display Technologies and Optical Communications

Governance Highlights

Corning is committed to maintaining strong corporate governance as a critical component of driving sustained shareholder value. The Board of Directors continually monitors emerging best practices in governance to best serve the interests of the Company's stakeholders.

Following is a brief overview of some of our most notable corporate governance practices and policies:

• Qualifying shareholders are permitted to include director nominees in the proxy statement ("proxy access");
• We contacted holders of approximately 45% of our common stock last year to discuss our executive compensation programs and corporate governance practices;
• We ensure alignment of our corporate governance practices with the Investor Stewardship Group's corporate governance Principles for U.S. Listed Companies (see page 17);
• We adopted the principles embodied in the Shareholder-Director Exchange (SDX) Protocol; and
• We continually enhance our disclosures regarding sustainability and environmental, social and governance practices.

The Corporate Governance section beginning on page 17 describes our governance framework, which includes the following:

• Annual election of all directors
• Majority vote standard for the election of directors in uncontested elections
• Active shareholder engagement, including by directors, to directly gather investor perspectives
• Active, engaged and experienced Lead Independent Director
• Independent board committees, with all committees (except the Executive Committee) consisting entirely of independent directors

• Regular executive sessions of independent directors
• Market competitive director compensation program designed to support and reinforce our governance principles
• Robust stock ownership guidelines for directors and key executive officers
• Prohibition on pledging, hedging or trading in derivatives of the Company's stock for directors and employees
• Clawback policy for executive incentive compensation in the event of certain financial restatements

Shareholder Communication

Communicating with shareholders, particularly about our Strategy & Growth Framework, is critically important to Corning. We communicate with our shareholders through a number of channels, including quarterly earnings calls, Securities and Exchange Commission (SEC) filings, Investor Days, investor conferences, our website at corning.comand other electronic communications. Our executives and Board members also routinely engage with investors through in-person meetings and calls.

In addition to regular discussions regarding our Strategy & Growth Framework, we also conduct outreach to the governance teams at our largest shareholders.

In 2019, as part of our shareholder outreach:

• we met with approximately 45% of our outstanding shares and approximately two-thirds of our fifty largest shareholders
• we discussed our 2016-2019 Strategy and Capital Allocation Framework, our 2020-2023 Strategy & Growth Framework, governance, compensation, human capital management and sustainability
• our investors expressed satisfaction with both of our strategic frameworks, as well as our executive compensation program

Environmental, Social and Governance Matters and Human Capital Management

In accordance with Corning's Values, we believe that a commitment to positive environmental, social and governance-related business practices strengthens our company and our community, increases our connection with our shareholders, and helps us better serve our customers and the communities in which our employees live and we operate. We also see in these commitments additional ways of creating value for our shareholders, our employees, our customers, and the wider world.

Corning demonstrates its commitment to environmental, social, governance and human capital matters, and its Values, in many ways that can be explored on our Sustainability website at corning.com/sustainability. Specifically:

• Corning is committed to protecting the environment through the continuous improvement of our processes, products, and services. For example:
• • For nearly fifty years, Corning has been a leader in developing clean-airtechnologies, investing more than $2 billion in the development of clean- air products and holding more than 600 environmental technology patents.
  • The U.S. Environmental Protection Agency has awarded Corning the ENERGY STAR® Partner of the Year for the last 6 years, with Sustained Excellence designation the last 4 years.

To date, Corning has 29 Challenge for Industry achievers.
  • Five new solar projects went online in 2019 at Corning facilities around the globe. To date, Corning has 15 solar projects up and running with a nameplate capacity of more than 58 megawatts.
  • In 2019, Corning co-sponsored the 6th Annual Harmful Algal Blooms (HABs) Symposium in an effort to further understand and help mitigate the effects of climate change, which contributes to HABs.
• Corning's formal commitment to diversity and inclusion began more than 50 years ago. Together with our Values, our diversity and inclusion initiatives unite us as "one Corning" worldwide and form the foundation of our shared workplace culture in which all employees have the opportunity to thrive.
• • Corning is a global employer with approximately 49,500 employees across the U.S., Asia, Latin America and Europe.
  • We achieved 100% pay equity for men and women in the U.S. in 2017 and in China and Taiwan in 2019, and we made significant progress in our other largest locations outside the U.S. comprising approximately 90% of our global workforce with the goal to have 100% of our salaried workforce included in our annual analyses by 2021.
  • Since 2006 we have increased diversity from 24% to 52% within our businesses and from 8% to 20% among corporate officers.
  • Corning's global salaried employee retention rate is 96%.
  • For the fourth year in a row, Corning was named to the "Best-of-the-Best" Corporations for Inclusion list by the National Gay & Lesbian Chamber of Commerce, distinguishing Corning as one of the "Best Places to Work for LGBT Equality" and earned a score of 100 on the Disability Equality Index and recognition as a "Best Place to Work" by the American Association of People with Disabilities and Disability:IN.
  • Corning has scored a 90 or above on the Human rights Campaign Corporate Equality Index for fifteen years.
  • Corning received recognition as a Top Supporter of Historically Black Colleges and Universities (HBCUs) for the sixteenth consecutive year by the Council of Engineering Deans of HBCUs.
• Corning's Human Rights Policy operates in conjunction with, and is mutually supportive of, our Code of Conduct, our Supplier Code of Conduct, our product stewardship programs, our global environmental, health and safety policies and procedures, and our compliance program. Together, these policies and practices demonstrate our firm commitment to respect and advance human rights. More information about these policies can be accessed through our Sustainability page linked above.
• In 2019, Corning's Sustainability team completed the Company's first materiality assessment to identify the ESG issues most important to the Company and its stakeholders.

Supporting Sustainable Communities

Throughout its history, Corning has routinely made contributions to civic, educational, charitable, cultural and other institutions that improve the quality of life and increase the resources of the communities in which it operates, making Corning more attractive to employees.

The Company undertakes its philanthropic activities both directly and indirectly through The Corning Incorporated Foundation (the Foundation), a separate 501(c)3 organization. We believe in being an active corporate citizen and the Foundation directs its grant-making toward the communities where Corning operates and its employees live, enabling initiatives in four areas: education, culture, human services and volunteerism. In 2019, Corning donated $4.0 million to the Foundation, and the Foundation disbursed approximately $5 million, of which approximately 33% was directed toward initiatives supporting education, including grants made under the Foundation's Employee Programs (Employee Matching Gifts, Dollars for Doers, Vibrant Community Grants and Excellence in Volunteerism Awards).. Additional information about the Foundation can be found at corningfoundation.org.

Corning's direct giving includes annual contributions to both local and international cultural and educational institutions. In particular, Corning is proud to support The Corning Museum of Glass (CMoG) - the world's leading glass museum. Beyond just a key cultural and community hub, CMOG also provides Corning with a unique innovation crucible where our glass scientists and experts collaborate with glass artists and designers to creatively explore the novel properties of glass and innovate new uses in an environment uninhibited by traditional commercial boundaries. In a small community, our employees, including executives and their families, inevitably have relationships with the non-profit organizations that receive such contributions from the Company. Wendell P. Weeks (chairman, CEO and president), David Morse (executive vice president and chief technology officer) and Jeffrey W. Evenson (executive vice president and chief strategy officer) serve on the CMoG board of trustees. In 2019, Corning provided cash and non-cash contributions of services to CMoG of approximately $45 million.

Corning provides financial support to the Alternative School for Math and Science (ASMS), a private middle school located in Corning, New York, with an advanced curriculum focusing on science and math. Currently, children of Corning employees represent approximately 51% of its enrollment. In 2019, non-cash contributions totaled approximately $1.6 million and cash contributions totaled $346,000. Kim Frock Weeks (spouse of Wendell P. Weeks, our chairman, CEO and president) serves on the ASMS board of trustees and also serves as executive head of school, but receives no salary or benefits in this role.

Proxy Statement Summary

Compensation Performance Metrics - Pay for Performance

Our goals for annual and long-term incentives in 2019 focused on the key drivers for successfully executing our Strategy and Capital Allocation Framework and creating and sustaining long-term shareholder value: profitability (Core EPS), top line growth (Core Net Sales) operating cashflow (Adjusted Operating Cash Flow) and prudent investing for growth (CapEx). While we successfully delivered the goals of the Framework, we missed our financial performance targets for executive compensation due to changing market and customer dynamics in Display Technologies and Optical Communications. Our executive compensation outcomes for 2019 were down accordingly.

Our Metrics and Why We Use Them

Core Earnings per Share (Core EPS):

Core EPS is our key measure of profitability. Corning generally budgets for share repurchases in establishing its target Core EPS measures.

Core Net Sales:

Sales growth, both organic through innovation and through acquisitions, is critical to our short- and long-term success.

Adjusted Operating Cash Flow:

Strong positive cash generation enables our ongoing investment in growth,

sustained leadership and returns to shareholders.

CapEx:

Making good decisions on where and when to invest for future growth is paramount to our long-term success

Return on Invested Capital (ROIC):

We focus on ROIC because it reflects our ability to generate returns from the capital we have deployed in our operations. The Cash Performance Units (CPUs) payout is increased or decreased up to 10% based on Corning's ROIC over the three-year performance period.

2019 Compensation Plan Payout Percentages

Corporate Governance

and the Board of Directors

Corporate Governance

Our Board of Directors employs practices that foster effective Board oversight of critical matters such as strategy, management succession planning, financial and other controls, risk management and compliance. The Board reviews our major governance policies, practices and processes regularly in the context of current corporate governance trends, investor feedback, regulatory changes and recognized best practices. Corning also aligns its corporate governance practices with the Investor Stewardship Group's (ISG) Corporate Governance Framework for U.S. Listed Companies.

The following sections provide an overview of our corporate governance structure and processes, including key aspects of our Board operations, and how they align with the ISG Principles.

Description

ISG Principle 5: Board should adopt structures and practices that enhance their effectiveness

Independence	Our Corporate Governance Guidelines require a substantial majority of our directors to be independent. Currently, all
directors but one (or 93%) are independent. Except for our Executive Committee, each of our Board committees
	consists entirely of independent directors. See page 24.
Skills and qualifications	Our Board is composed of accomplished professionals with deep experiences, skills, and knowledge relevant to our
business, resulting in a high-functioning and engaged Board. A matrix of relevant skills can be found on page 31.
Commitment to Diversity	The Board seeks to achieve diversity among its members and is committed to actively seeking out highly qualified
women and minority candidates, as well as candidates with diverse backgrounds, skills and experiences, to include
	in the pool from which Board nominees are chosen. See page 23.
	The current average tenure of members of our Board, excluding our CEO Mr. Weeks and our retiring director Mr.
	Canning, is 9.5 years. Our director retirement policy requires a director to retire at the annual meeting of
Director tenure	shareholders following the director's 74th birthday. The Board, upon a recommendation of the Nominating and
Corporate Governance Committee, may waive this limitation for any Director if the Board determines that it is in the
	best interests of the Company. In addition, a director is required to submit an offer of resignation for consideration by
	the Board upon any significant change in the director's principal employment or responsibilities.
	Corning values director participation on other public company boards as a means of adding depth to our governance
	and risk oversight practices. However, we have a policy to help provide confidence that each of our directors can

review and approval by the Nominating and Corporate Governance Committee, a non-employee director may serve
	on no more than three other public company boards and an employee director may serve on no more than two other
	public company boards.
	The Board and each committee conducts an annual review of its effectiveness. The Chair of the Nominating and

	ensure implementation.
Meeting attendance	Directors attended 95% of combined total Board and applicable committee meetings in 2019. See page 28.

ISG Principle 6: Boards should develop management incentive structures that are aligned with the long-term strategy of the company

Robust stock ownership	We require robust stock ownership for directors (5x annual cash retainer), CEO (6x base salary), other NEOs (3x
guidelines	base salary) and non-NEO senior management (1.5x base salary). See page 42.
Shareholder support for executive	Corning's executive compensation program received 94% shareholder support in 2019 and has averaged 92%

Corporate Governance and the Board of Directors

Board Leadership Structure

The Board regularly considers the issue of board leadership in committee meetings and executive sessions of the independent directors. As the Board reviews its leadership structure, it considers a variety of factors, with a particular focus on those described on page 31. The Company's Corporate Governance Guidelines provide that the Board must annually review whether the role of Chairman should be a non-executive position or combined with that of the CEO. In February 2020, the Board determined that, at the present time, our combined Chairman and CEO, supported by our strong Lead Independent Director continues to provide appropriate leadership and oversight and ensures effective functioning of management and the Company.

When the Chair and CEO roles are combined, as it is currently, our Corporate Governance Guidelines require that the independent directors annually appoint an independent director to serve as Lead Independent Director. The Lead Independent Director has significant authority and responsibilities with respect to the operation of the Board, as described below under the heading "Lead Independent Director." The Company believes that a Lead Independent Director enhances strong Board governance and oversight.

Richard T. Clark was re-appointed to the role of Lead Independent Director of the Board by the independent directors effective February 5, 2020.

Lead Independent Director

Richard T. Clark, retired Chairman, Chief Executive Officer and President of Merck & Co., Inc. is our current Lead Independent Director. His regular duties include:

• presiding at all meetings at which the Chair is not present, including executive sessions of the independent directors (which are held at every Board meeting);
• leading the Board's oversight of Corning's Strategy & Growth Framework;
• facilitating regular CEO performance reviews and ongoing management succession planning reviews;
• participating in conversations with the Company's shareholders;
• serving as liaison between the Chair and the independent directors;
• approving Board meeting agendas and schedules;

• approving the type of information to be provided to directors for Board meetings;
• calling meetings of the independent directors when necessary and appropriate; and
• performing such other duties as the Board may from time to time designate.
• meeting with the CEO after regularly scheduled Board meetings to provide feedback on the independent directors' deliberations; and
• regularly speaking with the CEO between Board meetings to discuss matters of concern, often following consultation with other independent directors.

Corporate Governance and the Board of Directors

Board Composition

Our Board is responsible for the oversight and success of our Company. We seek to maintain a mix of directors who bring strong leadership, diverse perspectives, a broad range of skills relevant to Corning and depth of experience to their positions. Our board is high-functioning and engaged. A supermajority of independent directors ensures robust debate and challenged opinions in the boardroom, while diversity of gender, age, ethnicity and expertise contributes to a wide range of views. Our Board includes three women, two African-Americans, and four directors who hold science, technology or mathematics Ph.Ds. We also have two decades of age diversity among our directors, with their ages ranging between 53 and 74 years. We also value the broad corporate governance experience of directors who have served on the boards of other public companies, which adds additional rigor to our governance and risk oversight practices.

CHARACTERISTICS OF OUR BOARD (EXCLUDING OUR CEO AND DIRECTOR RETIRING IN 2020)

Board Nomination and Refreshment Process

When considering Board candidates, the Nominating and Corporate Governance Committee considers those factors most relevant to the Company's needs, including relevant knowledge and experience, diversity of background, and expertise in areas including business, finance, accounting, science and technology, marketing, manufacturing, operations, international business, government and human capital management. The Committee assesses personal qualities of leadership, character, judgment, ethics and reputation; roles and contributions valuable to the business community and the ability to act on behalf of shareholders; whether the candidate is free of conflicts and has the time required for preparation, participation and meeting attendance. Pursuant to the Company's Corporate Governance Guidelines, the Committee actively seeks out highly qualified women and minority candidates, as well as candidates with diverse backgrounds, skills and experiences, to include in the pool from which Board nominees are chosen. The Board conducts an annual self-evaluation which helps identify skills and experiences to seek in future candidates that would benefit the Company, its stakeholders and the Board.

In the case of incumbent directors, the Nominating and Corporate Governance Committee will review such directors' overall service to the Company during their term, including the number of meetings attended, level of participation, quality of performance, and any transactions of such directors with the Company, if any, during their term. For those potential new director candidates who appear upon first consideration to meet the Board's selection criteria, the Nominating and Corporate Governance Committee will conduct appropriate inquiries into their background, qualifications and skills relevant to Corning's Strategy & Growth Framework and, depending on the result of such inquiries, arrange for in-person meetings with the potential candidates.

CORNING 2020 PROXY STATEMENT 23

Table of Contents

Corporate Governance and the Board of Directors

The Nominating and Corporate Governance Committee uses multiple sources for identifying director candidates, including executive search firms, its members' own contacts, and referrals from other directors, members of management and the Company's advisors. To maintain a pipeline for new directors, the Nominating and Corporate Governance Committee has retained the executive search firm of Spencer Stuart to help identify director prospects, perform candidate outreach, assist in reference and background checks, and provide other related services on an ongoing basis. Director candidates recommended by shareholders in the manner described on page 82 will be considered in the same manner in which the Nominating and Corporate Governance Committee evaluates candidates recommended by other sources. In addition, our by-laws permit a group of up to 20 shareholders who have owned a minimum of 3% of our outstanding capital stock for at least three years to submit director nominees for up to the greater of two directors or 20% of the board for inclusion in our proxy statement. See "How Do I Submit A Shareholder Proposal For, Or Nominate a Director For Election At, Next Year's Annual Meeting" on page 82 of this proxy statement.

Management Succession Planning

One of the Board's primary responsibilities is ensuring that Corning has a high-performing management team in place. The Company's CEO is supported by a Management Committee of eleven senior executives that oversee the full sphere of the Company's business, of which four are our other Named Executive Officers. The Board oversees management succession planning, with our Lead Independent Director facilitating ongoing review and Board approval of succession and management development plans for the CEO and Management Committee. The goal of this ongoing process is to maximize the pool of internal candidates able to assume top management positions with minimal business interruption. The Board regularly discusses succession planning for the chief executive officer and certain other senior management positions in executive sessions. The Board has regular engagement with various levels of management at Board and Committee meetings which gives directors additional exposure to the management pipeline. Each member of the Management Committee annually presents to fellow Management Committee members his or her own succession planning analysis.

Director Independence

Our Board is 93% independent and such independent oversight bolsters our success. Our Board has determined that each of our non-employee directors qualifies as "independent" in accordance with the listing requirements of the NYSE, applicable SEC rules and the Company's director qualification standards. Mr. Weeks is not independent because he is an executive officer of Corning.

The NYSE listing requirements state that no director may be qualified as "independent" unless our Board affirmatively determines that the director has no material relationship with Corning. When making independence determinations, the Board considers all relevant facts and circumstances which might bar a director from being determined to be "independent", including the NYSE criteria.

Our Corporate Governance Guidelines require the Board to make an annual determination regarding the independence of each of our directors. In making its independence determinations, the Board considered transactions, if any, that occurred since the beginning of 2017 between Corning and entities associated with our independent directors or members of their immediate family. The Board also reviewed and discussed information with regard to each director's business and personal activities as they may relate to Corning and Corning's management. It considered that each of Mr. Martin, and Drs. Huttenlocher and Wrighton are or were, during the previous three years, an employee of a company or organization that had a business relationship with Corning at some time during those years. The Board also considered: that Corning's business relationships with each such company or organization were ordinary course/arm's length dealings; no Corning director had a personal interest in, or received a personal benefit from, such relationships; any payments or contributions to or from each of these entities constituted less than the greater of $1 million, or 2% of such entity's consolidated gross revenues in each of those years; that such relationships arise only from such director's position as an employee of the relevant company with which Corning does business; that such director has no input or direct or indirect material interest in any of the business relationships or transactions; that such director had no role or financial interest in any decisions about any of these relationships or transactions; and that such a relationship does not bar independence under the NYSE listing requirements, applicable SEC rules or Corning's director qualification standards.

24 CORNING 2020 PROXY STATEMENT

Table of Contents

Corporate Governance and the Board of Directors

Based on all of the relevant facts and circumstances, the Board concluded that none of the director relationships mentioned above constituted a material relationship with Corning that represents a potential conflict of interest, or otherwise interferes with the exercise by any of these directors of his or her independent judgment with respect to Corning.

Policy on Transactions with Related Persons

The Board of Directors has a policy requiring the full Board or a designated Board committee to approve or ratify any transaction involving Corning in which one of our directors, nominees for director, executive officers, or greater than 5% shareholders, or their immediate family members, have a direct or indirect material interest and where the amount involved exceeds $120,000 in any fiscal year. The Board has delegated to the Nominating and Corporate Governance Committee the responsibility for reviewing and approving any such transactions.

In determining whether to approve or ratify any such transaction, the Board or relevant committee must consider, in addition to other factors deemed appropriate, whether the transaction is on terms no less favorable to Corning than transactions involving unrelated parties. No director may participate in any review, approval or ratification of any transaction if he or she, or his or her immediate family member, has a direct or indirect material interest in the transaction.

There were no such transactions requiring review and approval in accordance with this policy during 2019.

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee is now, or has ever been, an officer or employee of Corning. No member of the Compensation Committee had any relationship with Corning or any of its subsidiaries during 2019 pursuant to which disclosure would be required under applicable rules of the SEC pertaining to the disclosure of transactions with related persons. No Corning executive officer currently serves or served during 2019 on the board of directors or compensation committee of another company at any time during which an executive officer of such other company served on Corning's Board or Compensation Committee.

Corporate Governance and the Board of Directors

Risks associated with current business status or strategic alternatives are subjected to analysis, discussion and deliberation by management and the Board. Once a strategy is in place-such as the 2016-2019 Strategy and Capital Allocation Framework and the 2020-2023 Strategy and Growth Framework-the Board reviews it with the CEO at every Board meeting and discusses any newly-identified strategic risks.

Operationally, management reports periodically to the Board on the Company's enterprise risk management (ERM) policies and procedures, and to the Audit, Information Technology, Finance, and Corporate Relations Committees on our top risks and compliance policies and practices. Management also provides a comprehensive annual report of top risks to the Board. Corning's ERM program utilizes (1) a Risk Council chaired by the Executive Vice President and Chief Financial Officer and composed of Corning management and staff to aggregate, prioritize and assess risks, including strategic, financial, operational, business, reputational, governance and managerial risks; (2) an internal audit department; and (3) a Compliance Council, which reports directly to each of the Audit Committee and Corporate Relations Committee and reviews the Company's compliance with laws and regulations of the countries in which we conduct business.

The Board believes that the work undertaken by the committees of the Board, together with the work of the full board and the Company's management, enables the Board to effectively oversee Corning's management of risk.

Assessment of Company Culture

Our directors are positioned to assess Company culture in a number of ways. The Company's full Management Committee attends every Board meeting and numerous other members of management attend committee meetings. The Company's Chief Compliance Officer attends meetings of the Audit Committee and annually reports to the full Board and the Corporate Relations Committee. Formal dinners and informal lunches with meeting attendees provide Directors insight to how our teams function. When presenting an issue relevant to the Board, full business and technology teams attend to answer the Directors' questions and to join them at these dinners and lunches. Once a year the Board visits our research campus to meet with dozens of employees working on our key innovation initiatives. The Board also meets at different Corning locations - occasionally internationally - to see our manufacturing facilities, meet local managers and employees and explore the Company's culture. At the Company's annual meeting, all Company officers and their spouses are invited to attend the Board dinner and have opportunities for direct interaction.

Compensation Risk Analysis

In February 2020, the Compensation Committee reviewed the conclusions of a risk assessment of our compensation policies and practices covering all employees. This type of assessment is conducted annually by a cross-functional team with representatives from Human Resources (Compensation and Benefits), Law and Finance. The Compensation Committee evaluated the levels of risk-taking that potentially could be encouraged by our compensation arrangements, considering the arrangements' risk-mitigation features, to determine whether they are appropriate in the context of our strategic plan and annual budget, our overall compensation arrangements, our compensation objectives, and Corning's overall risk profile. Identified risk-mitigation features included the following:

• The mix of cash and equity payouts tied to both short-term financial performance, mid-term financial performance, and long-term value creation;
• The time vesting requirements in our long-term incentive plans, which help align the interests of employees to shareholders;
• The use of multiple financial performance metrics that are readily monitored and reviewed, and aligned with the corporate and business unit objectives;
• The rigorous budget and goal-setting processes that involve both top-down and bottom-up analyses;
• The use of common performance metrics for incentives across Corning's management team and all eligible employees with corporate results impacting the compensation of all Corning employees;
• Governance committees and plan caps that are intended to avoid imprudent risk-taking;

CORNING 2020 PROXY STATEMENT 27

Corporate Governance and the Board of Directors

• Our robust stock ownership, clawback, anti-hedging and anti-pledging policies for NEOs and other employees;
• Multiple levels of review and approval of awards, including Committee approval of all officer compensation; and
• Immediate oversight of executive pay matters in mergers and acquisitions and unit compensation throughout the acquisition integration process. The Committee concluded that Corning's executive compensation program is balanced and does not reward excessive financial risk-taking.

Corning does not use compensation policies or practices that create risks that are likely to have a material adverse effect on the Company.

Board and Shareholder Meeting Attendance

The Board of Directors met six times during 2019. Attendance at Board and committee meetings averaged 95% in 2019, and each incumbent director attended no less than 76% of the meetings of the Board and committees on which the director served.

The Board has a policy requiring all directors to attend our Annual Meeting, absent extraordinary circumstances. All of our directors attended our 2019 Annual Meeting of Shareholders except for Mr. Cummings who was absent due to illness.

Ethics and Conduct

We are committed to conducting business lawfully and ethically. Our directors, NEOs, and all Corning employees, are required to act at all times with honesty and integrity. We have a comprehensive Code of Conduct that applies to all Corning directors and employees that covers areas of professional conduct, including conflicts of interest, the protection of corporate opportunities and assets, employment policies, non-discrimination policies, confidentiality, vendor standards, and intellectual property, and requires strict adherence to all laws and regulations applicable to our business. Our Board spends meaningful time with executive management at board meetings, and other members of management at other board events, where the relationships developed enable the Board to ensure that the Company maintains a culture of integrity, responsibility and accountability throughout the organization.

We also have a supplemental "Code of Conduct for Directors and Executive Officers" that includes policies calling for strict observance of all laws applicable to our business, requires directors and executive officers to avoid any conflict between their personal interests and the interests of the company in dealing with suppliers, customers, and other third parties, and imposes standards upon certain conduct in their personal affairs, including transactions in securities of the Company, any company affiliate, or any unaffiliated organization. Each director and executive officer is expected to be familiar with and to follow these policies to the extent applicable to them. Any employee can provide an anonymous report of an actual or apparent violation of our Codes of Conduct. We will disclose any future amendments to, or waivers from, any provision of our Codes of Conduct involving our directors, our principal executive officer, principal financial officer, principal accounting officer, controller or other persons performing similar functions on our website within four business days following the date of any such amendment or waiver. No such waivers were sought or granted in 2019.

Lobbying and Political Contributions Policy

Corning encourages employees to participate in the political process on a personal basis. However, any use of Corning funds, property, resources or employee work time for U.S. political purposes - for example, to any U.S. political party, candidate or government official - is subject to Corning's Lobbying and Political Contributions Policy and must be approved in advance by Corning's Government Affairs office. Any contact with members of the U.S. Congress on behalf of Corning, or any Corning contribution to U.S. government officials or payment related to these officials, must be approved by and coordinated through Corning's Government Affairs office. Our policy can be found at corning.com/political-contributions.

Director Compensation

The Compensation Committee sets director compensation at levels that ensure our directors are paid appropriately for their time commitment and responsibilities relative to directors at companies of comparable size, industry and scope of operations. The Committee believes that providing a competitive compensation package is important because it enables Corning to attract and retain highly qualified directors who are critical to the Company's long-term success. Our objective is to pay non-employee directors competitively compared to comparable companies and to award a significant portion of director compensation in equity. The Compensation Committee's independent consultant, Frederic W. Cook & Co., Inc., conducts an annual review of the director compensation levels relative to Corning's compensation peer group and advises the Committee annually to ensure that compensation levels remain competitive.

The Company uses a combination of stock-based compensation and cash for its directors. Corning believes that a significant portion of director compensation should be linked to the Company's performance. Therefore, a portion of the Directors' compensation is paid as an annual equity grant of restricted share units, which are settled in shares of common stock following retirement or resignation from the Board.

Directors may defer receipt of the annual equity retainer restricted share units by electing distribution in up to 10 annual installments and also may defer all or a portion of their cash compensation. Cash amounts deferred may be allocated to: an account earning interest, compounded quarterly, at the rate equal to the prime rate of Citibank, N.A. at the end of each calendar quarter; a restricted stock unit account; or a combination of such accounts. In 2019, six directors elected to defer some or all of their cash compensation.

As an employee of the Company, Mr. Weeks is not compensated separately for service on the Board or any of its Committees.

2019 Director Compensation

The following table outlines 2019 director compensation:

Each non-employee director annually receives a form of long-term equity compensation approved by the Board. Annual equity grants for non-employee directors are generally approved at the February meeting of the Board. If, however, a director is appointed between the February meeting and December 31, then that director will receive a pro-rata grant shortly after joining the Board.

Annual Equity Grants

In 2019, our directors' annual equity grant was $175,000. We issued 5,182 restricted stock units (with a grant date value of approximately $175,000) to each non-employee director under our 2019 Equity Plan for Non-Employee Directors. These restricted stock units are not available for transfer or sale until six months after the date of a director's retirement or resignation.

Non-employee directors are reimbursed for expenses (including costs of travel, food, and lodging) incurred in attending Board, committee, and shareholder meetings. Directors are also reimbursed for reasonable expenses associated with participation in director education programs.

Directors' Charitable Giving Programs

Although closed to directors joining the Board after October 5, 2016, Corning has a Directors' Charitable Giving Program pursuant to which a director may direct the Company to make a charitable bequest to one or more qualified charitable organizations recommended by such director and approved by Corning in the amount of $1,000,000 (employee directors) or $1,250,000 (non-employee directors) following his or her death.

This program is either funded directly by the Company or by purchasing insurance policies on the lives of the directors. However, we are under no obligation to use the proceeds of the insurance policies to fund a director's bequest and can elect to retain any proceeds from the policies as assets of Corning and use another source of funds to pay the directors' bequests. In 2019, we paid a total of $68,628 in premiums and fees on such policies for our current directors. Because the charitable deductions and cash surrender value of life insurance policies accrue solely to Corning, the directors derive no direct financial benefit from the program, and we do not include these amounts in the directors' compensation. Generally, one must have been a director for five years to participate in the program. Directors who had not yet achieved five years' tenure as of October 5, 2016 will be permitted to participate after five years of Board service. In 2019, Messrs. Blair, Canning, Clark, Cummings, Landgraf, Martin, Tookes and Weeks, Ms. Henretta and Drs. Burns, Rieman and Wrighton were eligible to participate in the program.

Directors are also eligible to participate in the Corning Incorporated Foundation Matching Gifts Program for eligible charitable organizations. This Program is available to all Corning employees and directors. The maximum matching gift amount available from the Foundation on behalf of each participant in the Program is $7,500 per calendar year.

Corning also pays premiums on our directors' and officers' liability insurance policies.

Changes to Director Compensation in 2020

In February 2020, the Board approved certain changes to director compensation proposed by the Compensation Committee in consultation with the Committee's independent consultant. Effective January 1, 2020, the non-employee directors' annual equity grant increased from $175,000 to $185,000. As with the 2019 director equity compensation, this amount will be payable in restricted stock units, which are not available for transfer or sale until six months after the date of a director's retirement or resignation.

Stock Ownership Guidelines

We believe in the importance of equity ownership by directors and executive management as a direct link to shareholders, and require all directors, named executive officers (NEOs), and non-NEO executive management to achieve the required levels of ownership under our stock ownership guidelines within five years of their election, appointment or designation. Restricted, direct and indirectly owned shares, and current and deferred restricted stock units, each count toward our stock ownership guidelines. An NEO who falls below the ownership requirement for any reason will have up to three years to return to the required minimum ownership level. All directors and NEOs who have been so for five years or more currently comply with our guidelines.

Proposal 2

Advisory Approval of Executive Compensation (Say on Pay)

Our Board of Directors requests that shareholders approve the compensation of our Named Executive Officers (NEOs), pursuant to Section 14A of the Securities Exchange Act of 1934, as disclosed in this proxy statement, which includes the Compensation Discussion and Analysis, the Summary Compensation Table and the supporting tabular and narrative disclosure on executive compensation.

While this vote is advisory and not binding on the Company, the Board of Directors values shareholder opinion and will consider the outcome of the vote in determining our executive compensation programs.

Say on Pay Proposal

Our Board maintains a "pay for performance" philosophy that forms the foundation for all of the Compensation Committee's decisions regarding executive compensation. In addition, our compensation programs are designed to facilitate strong corporate governance, foster collaboration and support our short- and long-term corporate strategies.

The Compensation Discussion and Analysis portion of this proxy statement contains a detailed description of our executive compensation philosophy and programs, the compensation decisions the Compensation Committee has made under those programs and the factors considered in making those decisions, including 2019 Company performance and the direct alignment of pay with performance, focusing on the compensation of our NEOs. Our shareholders have affirmed their support of our programs in our outreach discussions and in their ongoing support of our Say on Pay proposals. We believe that we have created a compensation program deserving of shareholder support.

For these reasons, the Board of Directors recommends that shareholders vote in favor of the resolution:

RESOLVED, that the compensation paid to the Named Executive Officers disclosed in this proxy statement pursuant to the SEC's executive compensation disclosure rules (which includes the Compensation Discussion & Analysis, the Summary Compensation Table, and the supporting tabular and related narrative disclosure on executive compensation) is hereby APPROVED.

Our Metrics and Why We Use Them

Core Earnings per Share (Core EPS):

Core EPS is our key measure of profitability. Corning generally budgets for share repurchases in establishing its target Core EPS measures.

Core Net Sales:

Sales growth, both organic through innovation and through acquisitions, is critical to our short- and long-term success.

Adjusted Operating Cash Flow:

Strong positive cash generation enables our ongoing investment in growth,

sustained leadership and returns to shareholders.

ALL OTHER NEOs

CapEx:

Making good decisions on where and when to invest for future growth is paramount to our long-term success.

Return on Invested Capital (ROIC):

We focus on ROIC because it reflects our ability to generate returns from the capital we have deployed in our operations. The Cash Performance Units (CPUs) payout is increased or decreased up to 10% based on Corning's ROIC over the three-year performance period.

Compensation Discussion & Analysis

2019 Performance and Compensation Alignment

Each year our Compensation Committee sets rigorous and challenging performance goals aligned with our strategic objectives. The success of our strategic framework requires top line growth, overall profitability, the generation of operating cash flow, prudent investment for growth and delivery of long-term shareholder value.

Approximately 89% of the CEO's target total compensation (excluding employee benefits and perquisites) and 80% of the other NEOs' target total compensation (excluding employee benefits and perquisites) is variable and depends upon our operating performance or is linked to our stock price.

Net profitability and sales growth, both short- and long-term, drive success under our strategic framework. Accordingly, we have incentive measures linked to both short- and long-term outcomes. Our short-term incentives are cash bonuses composed of the Performance Incentive Plan (PIP) and the GoalSharing plan. Under the PIP, Core EPS (75% weight) measures bottom line profitability and Core Net Sales (25% weight) focuses on increasing top line growth. These two financial goals determine 100% of PIP payouts for NEOs. In 2019, actual performance was significantly below established PIP targets, with the blended result being a payout of 24% of PIP target (significantly lower than the 126% PIP payout in 2018). While 2019 was a challenging year for the Company, this result clearly demonstrates the alignment of our executive compensation with our financial performance.

GoalSharing is a company-wide plan that rewards our workforce based on the Company's and respective business unit's success (25% corporate financial performance/75% business unit performance weighting as outlined above). NEOs receive payouts based on the weighted average performance of all business unit plans, which in 2019 was 4.37% of base salary versus a target of 5% (down significantly compared to 6.41% in 2018).

Our Long-Term Incentive (LTI) program reflects our belief that (1) revenue growth and cash flows enable investments that will sustain our growth over the long term and (2) our executives' interests should aligned with our shareholders' interest. LTI awards are comprised of 60% Cash Performance Units (CPUs), 25% Restricted Stock Units (RSUs), and 15% Stock Options. CPU awards are based 35% on Adjusted Operating Cash Flow, 35% on CapEx and 30% on Core Net Sales, averaged over a three-year performance period. In addition to the above metrics, 2017 CPUs to be paid in 2020 are subject to an ROIC modifier of up to +/-10% based on ROIC performance over the three-year period 2017 through 2019. We define ROIC as core net income before interest, divided by invested capital. Core net income before interest is calculated using constant exchange rates for Japanese yen, South Korean won, Chinese yuan, new Taiwan dollar, and the euro against the U.S. dollar, and a constant tax rate. Invested capital is the sum of total assets excluding foreign currency hedge assets less total liabilities excluding foreign currency hedge liabilities and debt. The 2019 performance result for CPUs (impacting year 3 of the 2017-2019 CPUs, year 2 of the 2018-2020 CPUs and year 1 of the 2019-2021 CPUs) was 62% of target.

While 2019 was a challenging year for the Company, the compensation outcomes clearly illustrate the alignment of our executive compensation with Corning's financial performance.

	24%	126%
	Goalsharing payout (vs. 5% target)	4.37%	6.41%

2019 Company Performance Overview

In 2019, we delivered the commitments of the 2016-2019 Strategy and Capital Allocation Framework. While 2019 was a challenging year financially, we grew sales 2%, had strong performance in three segments, advanced key growth initiatives, and took action to address headwinds in Display Technologies and Optical Communications. However, our 2019 growth did not meet long-term targets and we accelerated actions in our Optical Communications and Display Technologies segments to align production output and working capital to match reduced customer demand, which impacted gross margin. Corning expects to build momentum throughout 2020 that will keep us on track to achieve the goals laid out in our four-year Strategy & Growth Framework.

ROIC Modifier

In 2016, based on investor feedback and in support of our Strategy and Capital Allocation Framework, the Compensation Committee added a three-year ROIC modifier to the CPUs in our LTI Plan. With this modifier, the CPU payout may be increased or decreased up to 10% based on ROIC performance over the three-year performance period. For the 2017-2019 performance period, the ROIC improvement target was established at 100 basis points, which the Committee believed was challenging but achievable through continued strong operating performance. The setting of this target reflected the multi-year operating plan for the Company and management's assessment of future Company performance. The ROIC modifier for 2017 CPUs (based on 2017 through

2019 performance) was as follows:

ROIC Improvement
2017 - 2019	Modifier (Adjustment to 2017 CPUs)
(in basis points)
250	+10%
175	+5%
100	No adjustment
50	-5%
0	-10%

From 2017 to 2019, ROIC improved 72 basis points, resulting in a 2.8% decrease to the 2017 CPU payout made in 2020.

Total Shareholder Return

Corning's Total Shareholder Return (TSR), which consists of stock price appreciation and reinvestment of common dividends, is shown below for 1, 3 and 5 year periods. The financial challenges of 2019 significantly impaired our 1-, 3- and 5-year TSR results. In the first three years of our 2016-2019Strategy and Capital Allocation Framework, TSR significantly outperformed the S&P 500 Index; however, 2019 TSR performance was disappointing as a result of headwinds in Display Technologies and Optical Communications. Nevertheless, we had strong performance in three segments, grew sales 2%, advanced key growth initiatives, and took action to address headwinds in the segments mentioned above. Although 2019 was a challenging year, our compensation outcomes demonstrate the direct alignment of our executive compensation program with the Company's performance.

Shareholder Engagement

Strong Say on Pay Results. At our 2019 Annual Meeting of shareholders, our Say on Pay proposal received support from 94% of votes cast. We have received 90% or greater support for our Say on Pay proposal each of the past three years. We view this level of shareholder support as an affirmation of our current pay practices and pay for performance philosophy.

Shareholder Outreach. In 2019, we met with shareholders representing approximately 45% of our outstanding shares, and approximately two-thirds of our top fifty shareholders. Additionally, executive management, Board members, Investor Relations and the Corporate Secretary engage annually with the governance teams of our largest investors to understand their perspectives on a variety of matters, including executive compensation, risk oversight, corporate governance policies and corporate sustainability practices.

We learned through these meetings that our investors are pleased with our strategic framework and believe we have clearly articulated how it creates shareholder value and how it is connected to management compensation. These shareholders also were generally supportive of our executive

compensation program, the direct linkage of financial metrics in our performance-based variable compensation plans to our strategic framework, and the addition of the ROIC modifier that was implemented in 2016 in response to investor feedback. As in previous years, shareholders were not prescriptive about compensation plan design. Instead, they were more interested to see that the results and outcomes delivered by the incentive plans were aligned appropriately with Corning's performance and had appropriately incented our executives to deliver on our strategic framework.

We also communicate with shareholders through a number of routine forums, including quarterly earnings presentations, U.S. Securities and Exchange Commission ("SEC") filings, the Annual Report and Proxy Statement, the annual shareholder meeting, investor meetings and conferences and web communications. We relay shareholder feedback and trends on corporate governance and sustainability developments to our Board and its Committees and work with them to both enhance our practices and improve our disclosures.

No tax gross-ups or tax assistance on perquisites

No repricing or cash buyout of underwater stock options without shareholder approval

No excise tax gross-ups for officer agreements entered into after July 2004

2019 Executive Compensation Program Details

Our key compensation program principles are as follows:

• Provide a competitive base salary
• Pay for performance
• Incent successful completion of our 2016-2019 Strategy and Capital Allocation Framework
• Apply a team-based management approach
• Increase the proportion of performance-based incentive compensation for more senior positions
• Align the interests of our executive group with shareholders

Base Salary

Base salaries provide a form of fixed compensation and are reviewed annually by the Committee, which considers internal equity and individual performance, as well as competitive positioning, as discussed in the "Compensation Peer Group" section starting on page 58. In 2019, Mr. Weeks' base salary increased by 3.25%, consistent with the salary increase budget for all other U.S. salaried employees. Base salaries of the remaining NEOs also increased by 3.25% in 2019.

Short-Term Incentives

Short-term incentives are designed to reward NEOs for Corning's consolidated annual financial performance supporting our strategic framework and team-based management approach. Corning has two short-term incentive plans: the Performance Incentive Plan (PIP) and GoalSharing.

CORNING 2020 PROXY STATEMENT 53

Table of Contents

Compensation Discussion & Analysis

PIP targets are established by the Committee each February as a percentage of the NEO's year-end salary depending on the competitive marketplace and his or her level of experience. In 2019, Mr. Weeks' PIP target was unchanged at 150% of year-end base salary. Mr. McRae's PIP target was 85% of year-end base salary and other NEOs had PIP targets of 80%. PIP targets are approved in February and payments are made by the following March 15 once the performance results are known. As outlined on page 50, the 2019 PIP payout will be 24% of target based on performance which was well below 2019 targets.

GoalSharing is designed to motivate employees to work together to achieve the most critical goals in each business unit. All Corning employees are eligible for GoalSharing with a target generally equal to 5% of base salary. Earned GoalSharing may be 0% - 10% of base salary, and is weighted 25% on corporate financial performance and 75% on business unit performance. The NEOs' GoalSharing is based 25% on corporate financial performance and 75% on the average of the results of all business unit plans. GoalSharing goals are approved in February each year and payments are made by the end of the following February once the performance results are known. As outlined on page 51, the 2019 GoalSharing payout for our NEOs was 4.37% of year-end base pay versus a target of 5%.

Long-Term Incentives

Long-Term Incentives (LTI) are comprised of cash and equity in the form of CPUs, RSUs, and stock options (Options). We believe it is important to link LTI metrics to financial measures that will drive the success of our strategic framework and generate long-term value for our shareholders. We also believe it is important for a significant portion of LTI to be in the form of equity to align our executives' stock ownership interests with those of our shareholders.

LTI targets are established by the Committee for each NEO annually in February. Mr. Weeks' 2019 LTI target was $9.75 million. Other NEOs' targets may be found in footnote 3 to the Summary Compensation Table on page 62 and range from $2.35 million to $2.55 million.

• CPUs represent 60% of the annual target LTI value. Payout is based on cash generation and revenue growth-measures that support our strategic framework as well as our long-term financial health and success. The performance measures for CPUs are 1) Adjusted Operating Cash Flow (35%), which aligns the cash flow goal to our capital allocation plan, 2) CapEx (35%) which maintains focus on prudent investment decisions and 3) Core Net Sales (30%). Actual CPUs earned are based on the actual performance averaged over a three-year period. CPUs awarded in 2019 were also subject to a three-year ROIC modifier of up to ±10% to further align compensation earned with the goal of our 2016-2019 Strategy and Capital Allocation Framework to improve our corporate ROIC. CPUs earned for the years 2019-2021 will be paid out (in 2022) based on pre-established performance goals.
• RSUs represent 25% of the annual target LTI value. The number of RSUs granted is determined based on the closing stock price on the first business day of April, and awards cliff vest approximately three years from the grant date.
• Options represent 15% of the annual target LTI value. The number of Options granted is determined using a Black-Scholes valuation. Options were granted on the first business day of April. Vesting is three years after the grant date, and the option awards have a maximum ten-year term.

CEO Compensation

Over the past fifteen years, under the leadership of Mr. Weeks, Corning has grown significantly, achieved the lowest cost position and market leadership in key businesses, and created new-to-the-world product categories, such as Corning® Gorilla® Glass, heavy-duty diesel substrates and filters, customized fiber-to-the- home solutions and Corning Valor® Glass.

In recognition of this track record of performance and particularly strong performance results in 2017 and 2018 in February 2019, the Compensation Committee approved a 3.25% base salary increase for Mr. Weeks and increased Mr. Weeks' LTI target to $9.75 million.

• Base salary - increased by 3.25%, in line with base salary increases for all other U.S. based salaried employees.
• Short-TermIncentives Target - remained flat at 155% of base salary, comprised of a PIP target of 150% of base salary and a GoalSharing target of 5% of base salary.
• Long-TermIncentives Target - increased to $9.75 million from $9 million

Year-over-year,eighty-nine percent of Mr. Weeks' pay is directly tied to Corning's operating performance and stock price. As a result, Mr. Weeks' year over year compensation in 2019 is significantly below that of 2018. The table below shows annual CEO pay (i.e., salary and incentive compensation) for 2018 and 2019, excluding employee benefits, perquisites and the change in pension value, which can fluctuate significantly year-to-year solely due to discount rate changes.

Employee Benefits and Perquisites

Employee Benefits: Our NEOs are eligible to participate in the same employee benefits plans as all other eligible U.S. salaried employees. These plans include medical, dental, life insurance, disability, matching gifts, qualified defined benefit and defined contribution plans. We also maintain non-qualified defined benefit and defined contribution retirement and long-term disability plans with the same general features and benefits as our qualified plans for all U.S. salaried employees affected by tax law compensation, contribution or deduction limits.

In addition to the standard benefits available to all eligible U.S. salaried employees, the NEOs are eligible for the benefits and perquisites described in this section.

Executive Supplemental Pension Plan (ESPP): We maintain an ESPP to reward and retain long-serving individuals who are critical to executing Corning's innovation strategy. Our non-qualified ESPP covers approximately 26 active participants, including all of the NEOs. In 2006, we capped the percentage of cash compensation earned as a retirement benefit under the ESPP at a maximum of 50% of final average pay for 25 or more years of service, a change that applies to all the NEOs except Dr. Morse. The definition of pay used to determine benefits includes base salary and annual cash bonuses. Long-term cash or equity incentives are not included and do not affect retirement benefits. Executives must have at least ten years of service to be vested under this plan. All of the NEOs meet the ten-year vesting requirement.

While we seek to maintain well-funded qualified retirement plans, we do not fund our non-qualified retirement plans.

For additional details of the ESPP benefits and plan features, please refer to the section entitled "Retirement Plans" on page 67.

Executive Physical and Wellness: All executives are eligible for an annual physical exam in addition to wellness programs sponsored by Corning for all employees. The cost of the physical is imputed income to the executive.

Relocation and Expatriate-RelatedExpenses: As part of our global mobility program, our policies provide that employees who relocate to another country at our request are eligible for certain relocation and expatriate benefits to facilitate the transition and international assignment. These benefits include moving expenses, allowances for housing and goods and services, and tax assistance. These policies are intended to recognize and compensate employees for incremental costs incurred with moving or with living and working outside of the employee's home country. The goal of these relocation and expatriate assistance programs is to ensure that employees are not financially advantaged or disadvantaged because of their relocation and/or international assignment, including related taxes. In July 2016, Mr. Clappin's assignment in Tokyo ended and he relocated back to Corning, NY. While he was based in Tokyo, Mr. Clappin was eligible for expatriate benefits. Tax-related assistance extends for several years beyond the assignment end due to LTI amounts earned while on assignment which vest after the assignment end date. These amounts are detailed in footnote 5, section (v) to the Summary Compensation Table.

56 CORNING 2020 PROXY STATEMENT

Table of Contents

Compensation Discussion & Analysis

Other Executive Perquisites: We provide the NEOs with an overall allowance that can be used for home security, modest personal aircraft usage, and limited financial counseling services. Each NEO is responsible for all taxes on any imputed income resulting from these perquisites.

Given the limited commercial flight options available in the Corning, New York area, the Committee believes that a well-managed program of limited personal aircraft use provides an extremely important benefit at a reasonable cost to the Company. We closely monitor business and personal usage of our planes and limit personal usage to keep it at a low percentage of total usage. The Committee establishes annual personal aircraft usage caps under this program (both hours and absolute dollar value) for each NEO. The established cap for the CEO was 100 hours and $170,000; the cap for the other NEOs was approximately half this level or lower. Actual utilization falls below these caps. For additional details, refer to footnotes relating to "All Other Compensation" included with the Summary Compensation Table starting on page 61.

Executive Severance: We have entered into severance agreements with each NEO. The severance agreements provide clarity for both Corning and the executive if the executive's employment terminates. By having an agreement in place, we avoid the uncertainty, negotiations and potential litigation that may otherwise occur in the event of termination. The agreements are competitive with market practices at many other large companies and are helpful in retaining senior executives. Additional details can be found under "Arrangements with Named Executive Officers" on page 70.

Executive Change-in-ControlAgreements: The Committee believes that it is in the best interests of shareholders, employees and the communities in which Corning operates to ensure an orderly process if a change in control were to occur. The Committee also believes it is important to prevent the loss of key management personnel (who would be difficult to replace) that may occur in connection with a potential or actual change in control. Therefore, we have provided each NEO with a change-in-control agreement (separate from the severance agreements described above). The change-in-control agreements provide that an executive's employment must be terminated or effectively terminated in connection with a change in control in order to receive severance benefits. Additional details about the specific agreements can be found under "Arrangements with Named Executive Officers - Change-in-Control Agreements" on page 72.

In 2012, the Committee approved updated forms of agreements for all corporate officers entering into change-in-control agreements after July 2004, which contain no provision for gross-ups for excise taxes, and cap severance and other benefits at 2.99 times base salary plus target bonus, with cash severance for most officers limited to 2 times base salary plus target bonus. Except for Mr. Tripeny, whose agreement is dated January 1, 2015, our current NEOs have grandfathered agreements that were entered into prior to July 2004.

Compensation Peer Group

Corning is a diversified technology company with five reportable business segments. The majority of our businesses do not have U.S. public company peers. Most of our businesses compete with non-U.S. companies in Asia and Europe, or privately-held companies that do not provide comparable executive compensation disclosure. In attempting to identify peer companies for compensation purposes, Corning must look to globally diversified companies or innovation companies in other industries to find organizations of similar size and complexity (when viewed in terms of revenues, net income, market capitalization, assets and number of employees). For these reasons, our peer group for compensation purposes does not closely resemble the companies with which we compete for business.

• Our largest competitors and most relevant financial performance peers are not U.S. public companies.

• Corning must look to globally diversified companies or innovation companies in other industries to find companies of similar size and complexity.

CORNING 2020 PROXY STATEMENT 57

Compensation Discussion & Analysis

We currently participate in and use several executive compensation surveys for NEO positions. Primary surveys are the Willis Towers Watson General Industry Executive Compensation Survey, the Equilar TrueValue Survey and Aon Hewitt Total Compensation Measurement Survey for Executives. The surveys provide general market data for relevant positions in companies with revenues and market capitalization similar to Corning's in both the technology industry and in general industry.

2019 Compensation Peer Group

The Compensation Peer Group in 2019 is set forth below. It is the same as the Compensation Peer Group in 2018.

Advanced Micro Devices, Inc.	Cummins Inc.	Medtronic, Inc.	TE Connectivity Limited
Agilent Technologies, Inc.	Danaher Corporation	Motorola Solutions, Inc.	Texas Instruments Incorporated

BorgWarner, Inc.	Eaton Corporation PLC	PPG Industries, Inc.
Boston Scientific Corporation	Harris Corporation	QUALCOMM, Inc.
Broadcom Corporation	Juniper Networks, Inc.	Rockwell Automation, Inc.

The Company selects a fair and challenging Compensation Peer Group as a reference point when setting its executive compensation. The Company's percentage ranking versus the Compensation Peer Group is near to or well-above the median in all measured categories.

PERCENT RANK, CORNING VERSUS COMPENSATION PEER GROUP

Corning uses the Compensation Peer Group solely as a reference point, in combination with broader executive compensation surveys, to assess each NEO's target total direct compensation (i.e., salary, target bonus, and the grant date fair value of long-term incentives). Our goal is to position our CEO's target total direct compensation within a competitive range of the Compensation Peer Group median. Median target total direct CEO compensation in the Compensation Peer Group was determined to be $13.6 million, and 75th percentile target total direct CEO compensation was $14.7 million, compared with Corning target total direct CEO compensation of $13.5 million. Beyond the CEO, external data serves as a reference point, with internal equity and individual performance and impact being more important considerations in establishing a base salary and target total direct compensation for the other NEOs.

Compensation Program - Other Governance Matters

Role of Compensation Consultant

The Compensation Committee has the authority to retain and terminate a compensation consultant, and to approve the consultant's fees and all other terms of such engagement. Since 2014, the Committee has retained an executive compensation expert from Frederic W. Cook & Co., Inc. (FW Cook) as its independent consultant.

In 2019, FW Cook attended all Committee meetings. FW Cook advises the Committee on all matters related to NEO and director compensation and assists the Committee in interpreting its data as well as data and recommendations received from the Company.

In 2019, the Company also engaged Compensation Advisory Partners LLC (CAP) and Willis Towers Watson (WTW) to assist management with various executive compensation matters.

The Committee conducted an independence review of FW Cook, CAP and WTW pursuant to SEC and NYSE rules, and concluded that the work of each firm for the Committee did not raise any conflicts of interest concerns. FW Cook provides no services to Corning other than the services rendered to the Committee.

Corning's senior vice president (SVP), Human Resources and SVP, Global Compensation and Benefits, working closely with other members of Corning's Human Resources, Law and Finance departments, are responsible for designing and implementing executive compensation programs and discussing with the Committee significant proposals or topics that affect executive compensation at the Company. The SVP, Global Compensation and Benefits, formulates the target total compensation recommendations for all of the NEOs (except the CEO) and reviews the recommendations for each of the other NEOs with the CEO. The NEOs do not recommend or suggest individual compensation actions that benefit them personally.

The CEO may propose adjustments he deems appropriate before management's recommendations are submitted to the Committee. Recommendations for the CEO's compensation are prepared by the Committee's independent compensation consultant (FW Cook) and are not discussed or reviewed with the CEO prior to the Committee's review and the CEO is not present for discussion of his compensation by the Committee.

After the annual budget is finalized each year, the Committee receives management's recommendations for the compensation plan performance metrics and sets the final targets for the year.

The CFO and the Controller typically attend the annual Committee meeting to review the CD&A and attends that portion of the February Committee meeting where performance metrics are reviewed.

Clawback Policy

Our clawback policy gives the Committee the sole and absolute discretion to make retroactive adjustments to any cash or equity-based incentive compensation paid to executive officers and other key employees if such payment was based upon the achievement of financial results that were subsequently the subject of a restatement. The Committee has discretion to seek recovery of any amount that it determines was received inappropriately by such individuals.

Anti-Hedging Policy

Our anti-hedging policy prohibits employees and directors from selling or buying publicly traded options on Corning stock, or trading in any Corning stock derivatives. Additionally, these individuals may not engage in transactions in which they may profit from short-term speculative swings in the value of Corning stock utilizing "short sales" or "put" or "call" options.

Anti-Pledging Policy

Our anti-pledging policy prohibits employees and directors from holding Corning stock in a margin account or pledging Company securities as collateral for a loan.

Tax Deductibility of Compensation

Historically, the Committee has made compensation decisions with an eye towards deductibility of performance-based pay under IRC Section 162(m). However, the Tax Cuts and Jobs Act of 2017 ("the Tax Act") that was signed into law December 22, 2017 eliminated the exemption from Section 162(m)'s deduction limit for performance-based compensation, effective for taxable years beginning after December 31, 2017. Compensation paid to our covered officers in excess of $1 million therefore will not be deductible unless it qualifies for transition relief.

Accounting Implications

In designing our compensation and benefit programs, we review the accounting implications of our decisions. We seek to deliver cost-effective compensation and benefit programs that meet both the needs of the Company and our employees.

Compensation Committee Report

The Compensation Committee of the Board of Directors (the Committee), which is composed entirely of independent directors, is responsible to the Board of Directors and our shareholders for the oversight and administration of executive compensation at Corning. The Committee approves the principles guiding the Company's compensation philosophy, reviews and approves executive compensation levels (including cash compensation, equity incentives, benefits and perquisites for officers) and reports its actions to the Board of Directors for review and, as necessary, approval. The Committee is responsible for interpreting Corning's executive compensation plans and programs. In the event of any questions or disputes, the Committee may use its judgment and/or discretion to make final administrative decisions regarding these plans and programs. It is our practice that all compensation decisions affecting a corporate officer must be reviewed and approved by the Committee. Additional details regarding the role and responsibilities of the Committee are defined in the Committee Charter, located in the Corporate Governance section of the Company's website.

The Committee has reviewed and discussed the foregoing CD&A with management. Based on our review and discussions with management, we recommended to the Board of Directors that the CD&A be included in this proxy statement and in our Annual Report on Form 10-K for the year ended December 31, 2019.

2019 Compensation Tables

2019 Summary Compensation Table

This table describes the total compensation paid to our NEOs for fiscal years 2019, 2018 and 2017, as required. The components of the total compensation are described in the footnotes below and in more detail in the tables and narratives that follow. For information on the role of each component of compensation, see the description under "Compensation Discussion and Analysis."

Our 2019 financial performance fell well short of our targets. As a result, 2019 compensation was significantly lower than 2018 compensation. CEO pay (i.e., base plus incentives) was down 35.9% year-over-year and NEO pay was down 32.4%, excluding employee benefits and perquisites and the change in pension value, which increased due to declining discount rates.

Compensation Discussion & Analysis

1. The amounts in the Non-Equity Incentive Plan Compensation column reflect the sum of annual short-term incentive payments and earned cash performance units. All of the annual cash bonuses paid to the NEOs are performance-based. Cash bonuses are paid annually through two plans: (i) GoalSharing; and (ii) the Performance Incentive Plan (PIP). Awards earned under the 2019 GoalSharing plan were 4.37% of each NEO's year-end base salary and paid in February 2020. Awards earned under the 2019 PIP were based on actual corporate performance compared to the Core EPS and Core Net Sales goals established for the plans in February 2019. Based on actual performance, each of the NEOs earned PIP awards equal to 24% of their annual target bonus opportunities (established as a percentage of year-end base salary). Cash awards earned under the PIP for 2019 will be paid in March 2020.

In addition to the 2019 PIP and GoalSharing awards noted above, the amounts in column (f) also reflect the earned portions of CPU awards granted in 2019, 2018 and 2017 on the basis of 2019 performance against established measures. 2019 CPU award payouts will be made in 2022 based on actual corporate performance compared to the established performance goals averaged over three years (2019, 2020 and 2021) and subject to a ±10% ROIC modifier as described on page 51. 2018 and 2017 CPU award payouts are based on performance goals averaged over three years (2018, 2019 and 2020) and (2017, 2018 and 2019) respectively and are also subject to a ±10% ROIC modifier. Adjusted Operating Cash Flow, CapEx and Core Net Sales goals for 2020 and 2021 are yet to be established. While the final payout amounts for 2019 and 2018 CPU awards are unknown, the table below reflects the earned amount of 2019, 2018 and 2017 CPU awards which are reflected in the Non-Equity Plan Compensation column above, on the basis of 2019 performance metrics which excludes the portion of the 2019 award that remains unearned because ROIC performance against targets (2020-2021) is not yet known and the portion of the 2018 award that remains unearned because ROIC performance against target (2020) is not yet known. The 3-year ROIC modifier for the period 2017-2019 was -2.8%. The Summary Compensation Table includes an adjustment for 2017 CPUs as shown in the table below as a result of this modifier.

• 2017 CPUs earned as a result of the ROIC modifier of -2.8% based on 2017-2019 ROIC performance against pre-established objectives

The amount disclosed in column (f) consists of the total (A) + (B) + (C) + (D) + (E) + (F) shown in this footnote (3).

1. The amounts in Change in Pension Value Column reflect the increase in the actuarial present value of the NEO's benefits under all defined benefit pension plans established by the Company determined using interest rate and mortality rate assumptions consistent with those used in the Company's financial statements. Although column (g) is also used to report the amount of above market earnings on compensation that is deferred under the nonqualified deferred compensation plan, Corning does not have any above market earnings under its nonqualified deferred compensation plan, also referred to as the Supplemental Investment Plan. In 2019 the discount rate used to value the actuarial liability decreased approximately 98 basis points from 4.29% to 3.31%. Discount rate changes over the past several years have resulted in significant year-to-year fluctuations in the present value of pension benefits as shown below:

Compensation Discussion & Analysis

1. The following table shows "All Other Compensation" amounts provided to the NEOs. Capped personal aircraft rights, financial counseling services and home security are the only perquisites offered to the NEOs. The value of the personal aircraft rights in the table below reflects the incremental cost of providing such perquisites and is calculated based on the average variable operating costs to the Company. Hourly rates are developed using variable operating costs that include fuel costs, mileage, maintenance, crew travel expense, catering and other miscellaneous variable costs. Fixed costs that do not change based on usage, such as pilot salaries, hangar expense and general taxes and insurance are excluded.

1. Amounts shown above reflect aircraft usage over 2019. Messrs. Weeks' and McRae's use of Corning aircraft for travel to external board meetings is also included.
2. NEOs may use their executive allowance for residential security or financial counseling services.
3. These amounts include costs attributable to executive physicals, including associated travel costs, an annual Board gift, and contributions made under the Corning Foundation Matching Gifts Program.
4. This reflects Company-paid expenses relating to personal and residential security benefitting Mr. Weeks and, through association, his family. Mr. Weeks' personal safety and security are of vital importance to the Company's business and prospects, and the Board considers these costs to be appropriate. However, because these costs can be viewed as conveying a personal benefit to Mr. Weeks, they are reported as perquisites in this column.
5. This reflects expenses pursuant to our standard global mobility program in connection with Mr. Clappin's assignment in Tokyo, Japan as President, Corning Glass Technologies. Mr. Clappin repatriated back to the U.S. in July 2016, but tax costs extend beyond the end of assignment because of LTI amounts earned during the assignment but which vest and are paid after the end of the assignment.

1. The amounts shown in columns (d), (e) and (f) reflect the award amounts under (i) the Company's 2019 Performance Incentive Plan (PIP) (ii) the 2019 GoalSharing Plan and (iii) the Cash Performance Units under the Corning 2019 Corporate Performance Plan. Awards under these plans are paid in cash. If the threshold level of performance is not met the payout will be 0%. If the performance target is met, the payout will be 100% of the target award. If the maximum level of performance is met for GoalSharing and PIP the payout will be 200% of the target award, and 165% for CPUs which represents the 150% performance metrics cap plus the maximum 10% ROIC modifier. PIP and GoalSharing awards are based on the individual's 2019 bonus target and year-end base salary. Actual awards earned for CPUs are based on average performance against established metrics over three years (2019, 2020, 2021), adjusted up or down by up to 10% based on ROIC results versus the pre- established goal for the three-year period, and will be payable in February 2022.

Retirement Plans

Qualified Pension Plan

Corning maintains a qualified defined benefit pension plan to provide retirement income to Corning's U.S.-based employees which was amended effective July 1, 2000, to include a cash balance component. All salaried and non-union hourly employees as of July 1, 2000, were given a choice to prospectively accrue benefits under the previously existing career average earnings formula or a cash balance formula, if so elected. Employees hired subsequent to July 1, 2000, earn benefits solely under the cash balance formula.

Benefits earned under the career average earnings formula are equal to 1.5% of plan compensation plus 0.5% of plan compensation on which employee contributions have been made. Under the career average earnings formula, participants may retire as early as age 55 with 5 years of service. Unreduced benefits are available when a participant attains the earlier of age 60 with 5 years of service or age 55 with 30 years of service. Otherwise, benefits are reduced 4% for each year by which retirement precedes the attainment of age 60. Pension benefits earned under the career average earnings formula are distributed in the form of a lifetime annuity with six years of payments guaranteed.

Benefits earned under the cash balance formula are expressed in the form of a hypothetical account balance. Each month a participant's cash balance account is increased by (1) pay credits based on the participant's plan compensation for that month and (2) interest credits based on the participant's hypothetical account balance at the end of the prior month. Pay credits vary between 3% and 8% based on the participant's age plus service at the end of the year. Interest credits are based on 10-year Treasury bond yields, subject to a minimum credit of 3.80%. Pension benefits under the cash balance formula may be distributed as either a lump sum of the participant's hypothetical account balance or an actuarial equivalent life annuity.

Messrs. Weeks, Clappin, McRae and Dr. Morse are earning benefits under the career average earnings formula. Mr. Tripeny is earning benefits under the cash balance formula. All of the active NEOs are currently eligible to retire under the plan.

Supplemental Pension Plan and Executive Supplemental Pension Plan

Since 1986, Corning has maintained non-qualified pension plans to attract and retain its executive workforce by providing eligible employees with retirement benefits in excess of those permitted under the qualified plans. The benefits provided under the Supplemental Pension Plan (SPP) are equal to the difference between the benefits provided under the Corning Incorporated Pension Plan and benefits that would have been provided thereunder if not for the limitations of the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended (the Code).

CORNING 2020 PROXY STATEMENT 67

Compensation Discussion & Analysis

Each NEO participates in the Corning Incorporated Executive Supplemental Pension Plan (ESPP). Participants in the ESPP receive no benefits from the SPP, other than earned SPP benefits under the cash balance formula prior to their participation in the ESPP, if any. Executives fully vest in their ESPP benefit upon attainment of age 50 with 10 years of service. All NEOs are fully vested in the ESPP.

Under the ESPP, participants earn benefits based on the highest 60 consecutive months of average plan compensation over the last 120 months immediately preceding the date of termination of employment.

A change in the benefits provided under the ESPP formula was approved in December 2006. Following the change, gross benefits determined under this plan are equal to one of two benefit formulas:

Formula A: 2.0% of average plan compensation multiplied by years of service up to 25 years.

Formula B: 1.5% of average plan compensation multiplied by years of service.

Benefits are determined under Formula A for all NEOs except for Dr. Morse, whose benefits are determined under Formula B.

Benefits earned under the Corning Incorporated Pension Plan and the cash balance formula of the SPP prior to ESPP participation, if any, will offset benefits earned under the ESPP.

Participants may retire as early as age 55 with 10 years of service. Unreduced benefits under Formulas A and B are available when a participant attains the earlier of age 60 with 10 years of service or age 55 with 25 years of service, provided their accrued benefit is less than four-times-the-annual-compensation limitation under Section 401(a)(17) of the Code ($1,120,000 in 2019). Participants with accrued benefits in excess of four times the annual compensation limitation under Section 401(a)(17) of the Code must be age 57 with 25 years of service to receive an unreduced benefit under the ESPP. Otherwise, benefits are reduced 4% for each year by which retirement precedes the attainment of age 60. Benefit reductions of 1% per year by which retirement precedes age 57 apply if the four-times-annual-compensation-limit rule noted above is in effect for the participant.

Benefits earned under the ESPP are distributed in the form of a lifetime annuity, with six years of payments guaranteed except for benefits earned under the cash balance formula of the SPP prior to becoming a participant in the ESPP, which is distributed as a lump sum of the participant's credited balance.

All NEOs are currently eligible to retire under the ESPP.

Pension Benefits

The table below shows the actuarial present value of accumulated benefits payable to each of the NEOs, including the number of years of service credited to each such NEO, under the qualified pension plan and the ESPP. These amounts were determined using interest rate and mortality rate assumptions consistent with those used in the Company's financial statements with the exception of the assumed retirement age and the assumed probabilities of leaving employment prior to retirement. Retirement was assumed to occur at the earliest possible unreduced retirement age for each plan in which the executive participates. For purposes of determining the earliest unreduced retirement age, service was assumed to be granted until the actual date of retirement. For example, an executive under the ESPP formula who is age 50 with 20 years

of service would be assumed to retire at age 55 due to eligibility of unreduced benefits at 25 years of service or age 57, if the four times annual compensation limit rule noted previously applies. No termination, disability or death was assumed to occur prior to retirement. Otherwise, the assumptions used are described in Note 12 to our Financial Statements for the year ended December 31, 2019, of our Annual Report on Form 10-K filed with the SEC on February 18, 2019.

1. Under Formula A, years of service are capped at 25 years, in determining benefits under the ESPP.
2. Under Formula B, years of service are not capped.

The compensation considered for purposes of determining benefits under the qualified pension plan and the ESPP for the NEOs is the "Salary" plus the GoalSharing and PIP cash bonuses set forth in the Summary Compensation Table. Bonuses are included as compensation in the calendar year paid. Long-term cash or equity incentives are not (and have never been) considered as eligible earnings for determining retirement benefits under these plans. For the 2019 calendar year, the NEOs eligible earnings and final average compensation were as follows:

Non-qualified Deferred Compensation

The table below shows the contributions, earnings and account balances for the NEOs in the Supplemental Investment Plan. Pursuant to the Company's Supplemental Investment Plan, the NEOs may choose to defer up to 75% of annual base salary and up to 75% of GoalSharing and PIP cash bonuses. The participant chooses from the same funds available under our Company Investment Plan (401(k)) in which to "invest" the deferred amounts. No cash is actually invested in the unfunded accounts under the Supplemental Investment Plan. Deferred amounts incur gains and losses based on the performance of the individual participant's investment fund selections. Participants may change their elections among these fund options. Corning does not have any above market earnings under its Supplemental Investment Plan. All of our current NEOs have more than three years of service with the Company, so all of the Company's matching contributions are fully vested. Participants cannot withdraw any amounts from their deferred compensation balances until retirement from the Company at or after age 55 with 5 years of service. Participants may elect to receive distributions as a lump sum payment or two to five annual installments. If an NEO leaves the Company prior to retirement, the account balance is distributed in a lump sum six months following the executive's departure.

The earnings on deferred base salary and bonus payments are calculated based on the actual returns from the same fund choices that Company employees have in the qualified 401(k) plan. Currently, employees have 14 fund choices that they may select from. As nonqualified plans, these plans are unfunded which means that no actual dollars are invested in these funds. The Company does not provide any above market interest rates or other special terms for any deferred amounts. These amounts are not included in the Change in Pension Value column of the Summary Compensation Table.

Arrangements with Named Executive Officers

Severance Agreements

We have entered into severance agreements with each of our NEOs. All new executive severance agreements and executive change-in-control agreements entered into after July 2004, limit the benefits that may be provided to an executive to 2.99 times the executive's annual compensation of base salary plus target incentive payments. Messrs. Weeks, Clappin, McRae and Dr. Morse have agreements which were in effect prior to July 2004. Mr. Tripeny has a severance agreement dated as of January 1, 2015.

Severance Agreements-Mr. Weeks

Under Mr. Weeks' severance agreement, if he is terminated involuntarily, and without cause, or as a result of disability, he is entitled to the following:

• Base salary, reimbursable expenses and annual bonus accrued and owing as of the date of termination (lump sum payment);
• A severance amount equal to 2.99 times his then-base salary plus an annual bonus amount (calculated at 100% of target that would have been paid for the fiscal year in which the termination occurs) (lump sum payment);
• Continued participation in the Company's benefit plans for up to three years; and
• In the calendar year following the year in which the termination occurs (subject to a six-month waiting period), the purchase of his principal residence by the Company upon request.

If however, Mr. Weeks is terminated for cause or he resigns, he would (1) be entitled to accrued, but unpaid salary (lump sum payment) and any reimbursable expenses accrued or owing to him and, if terminated for cause, (2) forfeit any outstanding stock awards.

Severance Agreements-Other Named Executive Officers

Under the severance agreements, an NEO is entitled to severance payments if he is terminated involuntarily other than for cause.

Generally, under the severance agreements, an NEO (other than Mr. Weeks) is entitled to receive the following:

• Accrued but unpaid base salary, reimbursable expenses, vacation pay and the executive's target percentage for the annual bonus plans multiplied by the executive's salary, pro-rated to the last day of the month closest to the termination date (lump sum payment);
• A severance amount equal to two times the executive's then-base salary plus an annual bonus amount (an amount equal to executive's salary multiplied by the executive's target percentage in effect on the termination date under the Company's Performance Incentive Plan and 5% target under the GoalSharing Plan) (lump sum payment);
• Continued medical, dental and hospitalization benefits for 24 months;
• In the calendar year following the year in which the termination occurs (subject to a six-month waiting period), the purchase of his principal residence by the Company upon request; and
• Outplacement benefits up to a maximum amount of $50,000.

The following table reflects the amounts that would be payable under the various arrangements assuming termination occurred at December 31, 2019.

Compensation Discussion & Analysis

1. Nonqualified plan benefits shown for all NEOs are payable from the Executive Supplemental Pension Plan. The timing and form of the benefits payable in the table above for a voluntary termination are as follows: Messrs. Weeks, Tripeny, McRae and Clappin's Executive Supplemental Pension Plan benefits are payable as an immediate life annuity. Dr. Morse's benefit is payable as an immediate life annuity with six years guaranteed.
2. The value of welfare benefits continuation is estimated at $17,673 per year for three years for Mr. Weeks and two years for Dr. Morse. Benefits continuation for Messrs. Tripeny and McRae is $26,774 per year for two years. Mr. Clappin's benefits continuation is $14,812 per year for two years.
3. Under the terms of the severance agreements, the NEOs may also request that Corning purchase their principal residence in the Corning, New York area. Corning is unable to accurately and precisely estimate the value that may be delivered under this provision as it requires an independent appraisal of the executive's residence as well as, for Mr. Weeks and Dr. Morse, a calculation of the executive's purchase price of the residence plus a percentage of documented improvements made to the property. These values are not maintained by Corning in its normal course of business. They are required only if an executive is terminated. Such purchase must be finalized in the calendar year following the year in which the executive's termination occurred (subject to a six-month waiting period). Mr. Clappin does not currently have a principal residence in the Corning, New York area.

Change-in-Control Agreements

We have entered into change-in-control agreements with each of the NEOs. These agreements are intended to provide for continuity of management if there is a change in control of the Company. These agreements will be effective until the executive leaves the employ of Corning or until the executive ceases to be an officer of Corning.

If during the term of the agreement a change in control occurs, the restrictions on all restricted stock and restricted stock units held by the NEO lapse, and any stock options vest and become immediately exercisable.

The NEOs are also entitled to severance and other benefits upon certain terminations of employment following or in connection with a change in control.

• For Mr. Weeks, benefits are payable if he (i) is terminated without cause or resigns for "good reason", each during a "potential change in control period" or (ii) resigns or is terminated for any reason or within four years following a change in control.
• For the NEOs (other than Mr. Weeks), benefits are payable if their employment is terminated (other than for cause, by reason of death or disability, or by the executive for any reason) during a potential change in control period, or within two years following a change in control.

The benefits payable are as follows:

• Accrued but unpaid base salary, reimbursable expenses, vacation pay and the executive's target percentage for the annual bonus plans multiplied by the executive's salary, pro-rated to the last day of the month closest to the termination date (lump sum payment);
• A severance amount equal to 2.99 times (for Mr. Weeks) and two times (for Messrs. McRae, Clappin, Tripeny and Dr. Morse) the NEO's then-current base salary plus an annual bonus amount (lump sum payment);
• Continued participation in the Company's benefit plans for 3 years;
• Upon request, purchase of the NEO's principal residence in the Corning, NY area; and
• Outplacement benefits (equal to 20% of base salary) (excluding Mr. Weeks).

If the employment of an NEO (other than Mr. Weeks) is terminated for cause or he resigns for other than good reason, or the NEO's employment terminates by reason of death or disability, the NEO is entitled to accrued but unpaid base salary, reimbursable expenses, vacation pay and the executive's target percentage for the annual bonus plans multiplied by the executive's salary, pro-rated to the last day of the month closest to the termination date (lump sum payment). In addition, each NEO except Mr. Tripeny is generally entitled to receive a gross-up payment in an amount sufficient to make him whole for any federal excise tax on excess parachute payments imposed under Section 280G and 4999 of the IRC. However, if the federal excise tax can be avoided by reducing the related payments by a present value of $45,000 or less, then the payment will be reduced to the extent necessary to avoid the excise tax and no gross-up payment will be made to the NEO.

1. Long-termincentives includes a combination of equity (stock options, and restricted stock units) and cash (cash performance units) which vest upon a change of control.

In addition to the above, the NEOs may also request that Corning purchase their principal residence. Corning is unable to accurately and precisely estimate the value as it requires an independent appraisal of the executive's residence and, for all, a calculation of the executive's purchase price of such residence and any documented improvements made to the property. This is data that Corning does not maintain in its normal course of business. See footnote (3) to the "Termination Scenarios" on page 71.

Pay Ratio Disclosure

For 2019, our last completed fiscal year, the annual total compensation of the median employee, excluding our CEO, was $49,121 and the annual total compensation of our CEO was $14,283,654. Accordingly, the ratio of the CEO's annual total compensation to the annual total compensation of the median employee was 291:1.

This reflects analysis of our global workforce of 50,155 employees as of October 1, 2019, which excludes 741 employees in Brazil, 94 employees in Hungary, 349 employees in India, 2 employees in Indonesia, 3 employees in Pakistan, 155 employees in South Africa, 77 employees in Turkey and 60 employees in Russia, which are de minimis. We used estimated total cash compensation to determine the median employee. Our estimate of total cash compensation for our full 2019 fiscal year included (i) annual base salary plus annual incentives calculated at target for salaried employees and (ii) hourly salary rate times annual standard hours plus additional adjustments for shift differentials, estimated overtime rates, production bonuses, holiday bonuses, fixed bonuses and other cash allowances paid to hourly employees.

Our estimates were based on an analysis of the pay components and payrolls in each of the 37 countries in which we operate, excluding Brazil, Hungary, India, Indonesia, Pakistan, Russia, South Africa and Turkey. Total cash compensation rates of employees paid in foreign currencies were converted into U.S. dollars using our standard monthly foreign exchange conversion rates in effect on October 1, 2019 for the determination of the median and December 31, 2019 for the year-end actual total compensation. Once the median employee was identified, actual total compensation was determined in accordance with Item 402(c)(2)(x) of Regulation S-K.

The SEC's rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Proposal 3

Ratification of Appointment of Independent Registered Public Accounting Firm

The Audit Committee (the Committee) evaluates our independent registered public accounting firm each year and has appointed PricewaterhouseCoopers LLP (PwC) as our independent registered public accounting firm for 2020. PwC has served in this role since 1944. The Committee concluded that many factors contribute to the continued support of PwC's independence, such as the oversight of the Public Company Accounting Oversight Board (PCAOB) through the establishment of audit, quality, ethics, and independence standards in addition to conducting audit inspections; the mandating of reports on internal control over financial reporting; PCAOB requirements for audit partner rotation; and limitations imposed by regulation and by the Committee on non-audit services provided by PwC. The Committee preapproves all audit and permitted non-audit services that PwC performs for the Company, and it approves the audit fees associated with the engagement of PwC. All services provided to Corning by PwC in 2018 and 2019 were pre-approved by the Committee in accordance with the policy.

The Committee and the PCAOB require key PwC partners assigned to our audit to be rotated at least every five years. The Committee and its Chair oversee the selection process for each new lead engagement partner. Throughout this process, the Committee and management provide input to PwC about the Company's priorities, discuss candidate qualifications and interview potential candidates put forth by the firm.

In determining whether to reappoint PwC, the Committee took into consideration a number of factors, including:

• PwC's global capabilities to handle the breadth and complexity of Corning's global operations;
• PwC's technical expertise and knowledge of Corning's industry and global operations;
• The quality and candor of PwC's communications with the Committee and management, which include routine executive sessions with the Committee held without management present and a management survey of PwC's performance;
• PwC's independence;
• The appropriateness of PwC's fees; and
• PwC's tenure as our independent registered public accounting firm, including the benefits of that tenure (including higher audit quality due to PwC's deep understanding of Corning's business and accounting policies and practices), the avoidance of significant costs and disruptions that would be associated with retaining a new independent auditor, and the controls and processes in place such as rotation of key partners and an annual assessment of PwC's qualifications, service quality, sufficiency of resources, quality of communications, working relationship with our management, objectivity and professional skepticism that help ensure PwC's continued independence.

Proposal 3 Ratification of Appointment of Independent Registered Public Accounting Firm

Based on its evaluation, the Committee believes that the continued retention of PwC is in the best interests of the Company and its shareholders. The Board concurs and requests that the shareholders ratify the appointment of PwC as Corning's independent registered public accounting firm for the fiscal year ending December 31, 2020. If the selection of PwC is not ratified by a majority of the shares of common stock present or represented at the annual meeting and entitled to vote on the matter, the Committee will review its future selection of an independent registered public accounting firm in light of that vote result. Even if the selection is ratified, the Committee in its discretion may appoint a different registered public accounting firm at any time during the year if the Committee determines that such change would be appropriate.

Corning expects representatives of PwC to be present at the Annual Meeting and available to respond to questions that may be raised there. These representatives may comment on the financial statements if they so desire.

FOR Our Board unanimously recommends a vote FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2020.

Fees Paid to Independent Registered Public Accounting Firm

Aggregate fees for professional services rendered by PwC in 2018 and 2019:

		2018		2019
Audit Fees	$	9,572,000	$	9,479,000
Audit-Related Fees		357,000		73,000

All Other Fees		58,000		13,000

Audit fees also include statutory audits of Corning's foreign jurisdiction subsidiaries, comfort letters, consents for other SEC filings and reviews of documents filed with the SEC.

Audit-RelatedFees. These fees are composed of professional services rendered in connection with procedures to translate certain financial statements for foreign subsidiaries, employee benefit plan audits, agreed-upon procedures and the evaluation of new accounting policies.

Tax Fees. These fees are composed of statutory tax compliance, assistance for Corning's foreign jurisdiction subsidiaries' tax returns, expatriate tax return compliance and other tax compliance projects.

Policy Regarding Audit Committee Pre-Approval of Audit and Permitted Non- Audit Services of Independent Registered Public Accounting Firm

The Audit Committee has adopted a policy for pre-approval of audit and permitted non-audit services by Corning's independent registered public accounting firm. The full Audit Committee approves annually projected services and fee estimates for these services and other major types of services. The Audit Committee chairman has been designated by the Audit Committee to approve any services arising during the year that were not pre-approved by the Audit Committee and services that were pre-approved, but for which the associated fees will materially exceed the budget established for the type of service at issue. Services approved by the chairman are communicated to the full Audit Committee at its next regular meeting. For each proposed service, the independent registered public accounting firm is required to provide supporting documentation detailing said service and confirm that the provision of such services does not impair its independence. The Audit Committee regularly reviews reports detailing services provided to Corning by its independent registered public accounting firm.

Report of the Audit Committee

The purpose of the Audit Committee is to assist the Board of Directors in its general oversight of Corning's financial reporting, internal controls and audit functions. The Audit Committee operates under a written charter adopted by the Board of Directors. The directors who serve on the Audit Committee have no financial or personal ties to Corning (other than director compensation and equity ownership as described in this proxy statement) and are all "financially literate" and "independent" for purposes of the New York Stock Exchange listing standards. The Board of Directors has determined that none of the Audit Committee members has a relationship with Corning that may interfere with the members' independence from Corning and its management.

The Audit Committee met with management periodically during the year to consider the adequacy of Corning's internal controls and the objectivity of its financial reporting. The Audit Committee discussed these matters with Corning's independent registered public accounting firm and with the appropriate financial personnel and internal auditors. The Audit Committee also discussed with Corning's senior management and independent registered public accounting firm the process used for certifications by Corning's chief executive officer and chief financial officer that are required for certain of Corning's filings with the SEC. The Audit Committee met privately with both the independent registered public accounting firm and the internal auditors, both of whom have unrestricted access to the Audit Committee.

The Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent registered public accounting firm. Management is responsible for: the preparation, presentation and integrity of Corning's financial statements; accounting and financial reporting principles; establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)); establishing and maintaining internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)); evaluating the effectiveness of disclosure controls and procedures; evaluating the effectiveness of internal control over financial reporting; and evaluating any change that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting. The independent registered public accounting firm is responsible for performing an independent audit of the consolidated financial statements and expressing an opinion on the conformity of those financial statements with accounting principles generally accepted in the United States, as well as expressing an opinion on the effectiveness of internal control over financial reporting.

During the course of 2019, management updated the documentation, and performed testing and evaluation of Corning's system of internal control over financial reporting in response to the requirements set forth in Section 404 of the Sarbanes-Oxley Act of 2002 and related regulations. The Audit Committee was kept apprised of the progress of the evaluation, and it provided oversight and advice to management during the process. In connection with this oversight, the Audit Committee received periodic updates provided by management, internal audit and the independent registered public accounting firm at each regularly scheduled Audit Committee meeting. At the conclusion of the process, management provided the Audit Committee with, and the Audit Committee reviewed a report on, the effectiveness of Corning's internal control over financial reporting. The Audit Committee also reviewed: the report of management contained in Corning's Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC; as well as PricewaterhouseCoopers LLP's Report of Independent Registered Public Accounting Firm included in Corning's Annual Report on Form 10-K for the year ended December 31, 2019 related to its audits of the consolidated financial statements and financial statement schedule, and the effectiveness of internal control over financial reporting.

Proposal 3 Ratification of Appointment of Independent Registered Public Accounting Firm

The Audit Committee has discussed with the independent registered public accounting firm the matters required by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. In addition, the Audit Committee has received from the independent registered public accounting firm the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence and discussed with them their independence from Corning and its management. The Audit Committee has considered whether the provision of permitted non-audit services by the independent registered public accounting firm to Corning is compatible with the auditor's independence.

Based on these reviews and discussions, the Audit Committee recommended to the Board of Directors and the Board of Directors approved that the audited financial statements be included in Corning's Annual Report on Form 10-K for the year ended December 31, 2019.

Frequently Asked Questions About the Meeting and Voting

Who is Entitled to Vote?

You may vote if you owned our common shares as of the close of business on March 2, 2020, the record date for the Annual Meeting.

How Many Votes Do I Have?

You are entitled to one vote for each common share you own. As of the close of business on March 2, 2020, we had 762,620,093 common shares outstanding. The shares held in our treasury are not considered outstanding and will not be voted or considered present at the meeting.

How Do I Vote By Proxy Before the Annual Meeting?

Before the meeting, registered shareholders may vote shares in one of the following three ways:

• By Internet at www.proxyvote.com;
• By telephone (from the United States and Canada only) at 1-(800)-690-6903; and
• By mail by completing, signing, dating and returning the enclosed proxy card in the postage paid envelope provided (see instructions on proxy card). Please refer to the proxy card for further instructions on voting by Internet or telephone.
  Please use only oneof the three ways to vote.

If you hold shares in the account of or name of a broker, your ability to vote those shares by Internet and telephone depends on the voting procedures used by your broker, as explained below under "How Do I Vote If My Broker Holds My Shares In "Street Name"?"

May I Vote My Shares in Person At the Annual Meeting?

Yes. You may vote your shares at the meeting if you attend in person, even if you previously submitted a proxy card or voted by Internet or telephone. Whether or not you plan to attend the meeting, however, we strongly encourage you to vote your shares by proxy before the meeting.

May I Change My Mind After I Vote?

Yes. You may change your vote or revoke your proxy at any time before the polls close at the meeting. You may change your vote by:

• signing another proxy card with a later date and returning it to Corning's Corporate Secretary at One Riverfront Plaza, Corning, NY 14831, prior to the meeting;
• voting again by Internet or telephone prior to the meeting; or

Frequently Asked Questions About the Meeting and Voting

What Shares Are Included on My Proxy Card?

Your proxy card includes shares held in your own name and shares held in any Corning plan. You may vote these shares by Internet, telephone or mail, as described on the enclosed proxy card. Your proxy card does not include any shares held in a brokerage account in the name of your bank or broker (such shares are said to be held in "street name").

How Do I Vote if I Participate in the Corning Investment Plan?

If you hold shares in the Corning Investment Plan, which includes shares held in the Corning Stock Fund in the Company's 401(k) plan, these shares have been added to your other holdings on your proxy card. Your completed proxy card serves as voting instructions to the trustee of the plan. You may direct the trustee to vote your plan shares by submitting your proxy vote for those shares, along with the rest of your shares, by Internet, telephone or mail, all as described on the enclosed proxy card. If you do not instruct the trustee to vote, your plan shares will be voted by the trustee in the same proportion that it votes shares in other plan accounts for which it did receive timely voting instructions.

How Do I Vote if My Broker Holds My Shares in "Street Name"?

If your shares are held in a brokerage account in the name of your bank or broker (this is called "street name"), those shares are not included in the total number of shares listed as owned by you on the enclosed proxy card. Instead, your bank or broker will send you directions on how to vote those shares.

Will My Shares Held in Street Name be Voted if I Do Not Provide My Proxy?

Under the New York Stock Exchange rules, if you own shares in "street name" through a broker and do not vote, your broker may not vote your shares on proposals determined to be "non-routine." In such cases, the absence of voting instructions results in a "broker non-vote." Broker non-voted shares count toward achieving a quorum requirement for the Annual Meeting, but they do not affect the determination of whether the non-routine matter is approved or rejected. The proposal to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm is the only matter in this proxy statement considered to be a routine matter for which brokers will be permitted to vote on behalf of their clients, if no voting instructions are furnished. Since Proposals 1 and 2 are non-routine matters, broker non-voted shares will not count as votes cast to affect the determination of whether those proposals are approved or rejected. Therefore, it is important that you provide voting instructions to your broker.

What if I Return My Proxy Card or Vote by Internet or Telephone but Do Not Specify How I Want to Vote?

If you sign and return your proxy card or complete the Internet or telephone voting procedures, but do not specify how you want to vote your shares, we will vote them as follows:

• FOR all 13 director nominees (Proposal 1);
• FOR the advisory approval of the Company's executive compensation, as such information is disclosed in the Compensation Discussion & Analysis, the compensation tables and the accompanying disclosure (Say on Pay) (Proposal 2); and
• FOR ratification of the Board's appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2020 (Proposal 3).

If you participate in the Corning Investment Plan and do not submit timely voting instructions, the trustee of the plan will vote the shares in your plan account in the same proportion that it votes shares in other plan accounts for which it did receive timely voting instructions, as explained above under the question "How Do I Vote If I Participate In The Corning Investment Plan?"

Frequently Asked Questions About the Meeting and Voting

Why Haven't I Received a Printed Copy of the Proxy Statement or Annual Report?

We are furnishing proxy materials to you online, as permitted by SEC rules, to expedite your receipt of materials while lowering costs and reducing the environmental impact of printing and mailing full sets of annual meeting materials. If you received by mail a notice of the electronic availability of these materials, you will not receive a printed copy unless you specifically request it. Such notice contains instructions on how to request a paper copy of the materials.

Is the Proxy Statement Available on the Internet?

Yes. Most shareholders will receive the proxy statement and other annual meeting materials online. If you received a paper copy, you can also view these documents online by accessing our website at corning.com/2020-proxy. You can elect to receive future proxy statements and annual reports by Internet instead of receiving paper copies by mail by following the instructions for making such election when you electronically vote your shares.

Are You "Householding" For Shareholders Sharing the Same Address?

Yes. The SEC's rules regarding the delivery to shareholders of proxy statements, annual reports, prospectuses and information statements permit us to deliver a single copy of these documents to an address shared by two or more of our shareholders. This method of delivery is referred to as "householding," and can significantly reduce our printing and mailing costs. It also reduces the volume of mail you receive. This year, we are delivering only one proxy statement and 2019 Annual Report to multiple registered shareholders sharing an address, unless we receive instructions to the contrary from one or more of the shareholders. We will still be required, however, to send you and each other shareholder at your address an individual proxy voting card. If you would like to receive more than one copy of this proxy statement and our 2019 Annual Report, we will promptly send you additional copies upon written or oral request directed to Broadridge Financial Solutions, Inc. ("Broadridge"), either by calling toll free at [phone] or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717. The same phone number and mailing address may be used to notify us that you wish to receive a separate proxy statement or Annual Report in the future, or to request delivery of a single copy of a proxy statement or Annual Report if you are receiving multiple copies.

Code of Ethics

Our Board of Directors has adopted the Code of Ethics for the Chief Executive Officer and Financial Executives and the Code of Conduct for Directors and Executive Officers, which supplements the Code of Conduct governing all employees and directors. A copy of the Code of Ethics is available on our website at investor.corning.com/investor-relations/governance/overview/default.aspx. We will disclose any amendments to, or waivers from, the Code of Ethics on our website within four business days of such determination. During 2019, no amendments to or waivers of the provisions of the Code of Ethics were made with respect to any of our directors or executive officers.

Incorporation by Reference

The Compensation Committee Report on page 60 and the Report of Audit Committee of the Board of Directors on page 76, are not deemed filed with the SEC and shall not be deemed incorporated by reference into any prior or future filings made by Corning under the Securities Act or the Exchange Act, except to the extent that Corning specifically incorporates such information by reference. In addition, this proxy statement includes several website addresses. These website addresses are intended to provide inactive, textual references only. The information on these websites is not part of this proxy statement.

CORNING INCORPORATED AND SUBSIDIARY COMPANIES

CORE PERFORMANCE MEASURES

In managing the Company and assessing our financial performance, we adjust certain measures provided by our consolidated financial statements to exclude specific items to report core performance measures. These items include gains and losses on our translated earnings contracts, acquisition-related costs, certain discrete tax items and other tax-related adjustments, restructuring, impairment, and other charges or 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 and Specialty Materials segments for the Japanese yen, South Korean won, Chinese yuan and new Taiwan dollar currencies. Effective January 1, 2019, Corning also began using constant- currency reporting for our Environmental Technologies and Life Sciences segments for the euro, Japanese yen and Chinese yuan. 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 our earnings and cash flows. Corning also believes that reporting core performance measures provides investors greater transparency to the information used by our management team to make financial and operational decisions.

Core performance measures are not prepared in accordance with Generally Accepted Accounting Principles in the United States ("GAAP"). We believe investors should consider these non-GAAP measures in evaluating our results as they are more indicative of our core operating performance and how management evaluates our 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.

Effective July 1, 2019, we replaced the term "Core Earnings" with "Core Net Income". The terms are interchangeable and the underlying calculations remain the same.

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

(1)		Constant-currencyadjustment: 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-denominateddebt: 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-relatedcosts: These expenses include intangible amortization, inventory valuation adjustments and external acquisition-related deal costs.
(5)		Discrete tax items and other tax-relatedadjustments: 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-operationaltax-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.
(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-marketadjustment: 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.
