A Letter from Our Chairman and CEO

Dear Fellow Shareholder,

This year we mark Corning's 175th birthday. Not only are we among the oldest companies currently listed on the S&P 500, but we just closed out 2025 with all-time record core sales and core EPS and have an incredibly exciting growth outlook.

The basis of our success begins with Springboard. Two years ago, we outlined our plan to capture strong sales growth, as our innovative products and deep customer relationships positioned us to capitalize on important secular trends.

Since we had the capacity in place to support the growth, we also expected deliver a significantly enhanced return profile, with profits growing faster than sales. We set a core operating margin target of 20% by the end of 2026 to track our progress and said we also expected significant improvements in core EPS, core ROIC, and adjusted free cash flow.

Two years into the plan, Springboard has been a tremendous success. Overall, we have fundamentally transformed the company's financial profile. We believe we now have a highly profitable launch point for future growth, and we enter 2026 on an exciting journey to extend our success in the coming years. What an exciting way to mark Corning's 175<sup>th</sup> anniversary, a feat so few companies ever attain.

Going forward, we plan to maintain our long-term approach to value creation. Through an unwavering commitment to life-changing innovation, we provide durable, profitable growth and long-term value for our shareholders by inventing category-defining products, developing scalable manufacturing platforms, and building strong, trust-based relationships with our people and communities and our customers who are leaders in their industries. And all of our actions are grounded in a distinct set of Values, which guide everything we do.

I thank you, our shareholders, for being on this journey with us. We work hard every day to earn your trust and reward your confidence in us.

I hope you are as excited as I am about Corning's next 175 years of life-changing innovation. We look forward to sharing more details at our Annual Meeting.

\*Refer to Appendix A for more information.

**CORE PERFORMANCE MEASURES**

In managing the Company and assessing our financial performance, we adjust certain measures included in our consolidated financial statements to exclude specific items to arrive at measures that are not calculated in accordance with accounting principles generally accepted in the United States of America ("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.

&nbsp;&nbsp;&nbsp;**Our management uses core performance measures, along with GAAP financial measures, to make financial and operational decisions. These measures also form the basis of our compensation program metrics. Management believes that our core performance measures are indicative of our core operating performance and provide investors with greater visibility into how management evaluates our results and trends, and makes business decisions.**

Items that are excluded from certain core performance measure calculations include: the impact of translating foreign-denominated debt, the impact of translated earnings contracts, acquisition-related costs, certain discrete tax items and other tax-related adjustments, restructuring, impairment and other charges and credits, certain litigation, regulatory and other legal matters, pension mark-to-market adjustments and other items which do not reflect ongoing operating results of the Company.

In addition, because a significant portion of our revenues and expenses are denominated in currencies other than the U.S. dollar, management believes it is important to understand the impact on sales and net income of translating these currencies into U.S. dollars. Therefore, Corning utilizes constant-currency reporting for our Optical Communications, Display, Specialty Materials, Automotive and Life Sciences segments to exclude the impact from the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro, as applicable to the segment. **We believe that the use of constant-currency reporting allows management to understand our results without the volatility of currency fluctuations, analyze underlying trends in the businesses and establish operational goals and forecasts.** More information on these items can be found in Appendix A.

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

Proxy Statement Summary

2025 Performance Highlights: Springboard Delivers Enhanced Financial Profile and Continued Momentum

In 2025, Corning delivered another excellent year, building on the early success of our Springboard plan and fundamentally transforming the financial profile of the Company. Our results reflect strong execution against our Springboard objectives—driving higher sales, expanding profitability, and significantly increasing returns and free cash flow.

**Full-Year 2025: Achieving Milestones while Delivering Exceptional Results** 

For the full year 2025:

• We
 delivered double-digit core sales growth and **delivered on our high-confidence Springboard sales plan a full year early.** 

• Core
 EPS grew twice as fast as sales, with full-year core EPS at $2.52.

• Adjusted
 free cash flow grew three times as fast as sales, reaching $1.72 billion for the full year, **nearly doubling since the launch of Springboard.** 

• We **expanded core operating margin by 180 basis points** year over year.

Additionally, in the fourth quarter of 2025, we delivered core operating margin of 20.2%, achieving our Springboard core operating margin target of 20% a full year early.

Taken as a whole, 2025 demonstrated the strong incrementals of our Springboard plan, with a greater than 20% core operating margin, core ROIC in the low teens, and stronger cash generation.

Overall, the first two years of Springboard have been a tremendous success—establishing a highly profitable launch point for future growth. With an upgraded high-confidence Springboard growth plan and long-term, de-risked contracts with major customers, Corning is well positioned to continue this momentum into 2026 and beyond, generating strong profit and cash flow as demand for our products and capabilities continues to grow.

**During 2025, We Bolstered Key Partnerships while Expanding Our Capacity and Capability**

• We
 announced long-term agreements with key customers, including **a multiyear, up to $6-billion-dollar agreement with Meta to accelerate the buildout of the most advanced data centers in the U.S.** to support Meta's apps, technologies, and AI ambitions using our newest innovations
 in optical fiber, cable, and connectivity solutions. We continue to pursue similarly structured
 long-term agreements with other key customers in order to allow Corning to provide secure
 U.S. origin production of our most advanced Gen AI, high density innovations, while appropriately
 sharing the cost and risk of such expansions with customers.

• We
 announced a major expansion of our long-standing partnership with Apple, whereby **Apple made a new $2.5 billion commitment to produce all of the cover glass for iPhone and Apple Watch in Corning's Harrodsburg, Kentucky, manufacturing facility.** This means that
 100 percent of the cover glass on iPhone and Apple Watch units sold worldwide will be made
 in the U.S. for the first time. We believe this creates a larger, longer term opportunity
 for Corning in mobile consumer electronics.

• **We built the largest solar ingot and wafer facility in the United States**, co-located with
 our polysilicon facility in Hemlock, Michigan. This investment represents a step forward
 in one of our newest businesses where we are applying deep materials science expertise to
 bring a "More Corning" content approach in Solar.

• We
 announced that **the upcoming Samsung Galaxy S25 Edge will feature Corning<sup>®</sup> Gorilla<sup>®</sup> Glass Ceramic 2**, a new glass ceramic offering that delivers advanced
 protection in a new, remarkably thin device form factor.

**Sharing our Success with Our Stakeholders**

During 2025, we continued to return capital to our shareholders. We have consistently paid a quarterly dividend to our holders of record, which we held steady in 2025 at $1.12, representing a 27.3% increase since 2020. Additionally, we have coupled our regular dividends with opportunistic share repurchases. In 2025 alone we returned more than $1.1 billion to our shareholders through dividends and repurchases.

&nbsp;&nbsp;**Our Total Shareholder Return (TSR) consists of stock price appreciation and reinvestment of common dividends. Our 1-, 3-, and 5-year TSR performance of approximately 88%, 198%, and 179%, respectively, has significantly outperformed each of the S&P 500, S&P 500 Equal Weight Index (S&P EW), and our Compensation Peer Group over each such period as presented below.**

We achieve this through a balanced mix of base salary and annual and long-term incentives, with a substantial portion of compensation tied directly to the Company's financial, operational, and strategic results. Our programs promote sustained leadership accountability through robust governance, strong share ownership requirements, and risk-mitigation practices, ensuring we attract, motivate, and retain top talent while upholding transparency and responsible business conduct. Our Board of Directors recommends that shareholders vote in favor of the resolution approving our executive compensation as found on page 53.

**2025 Compensation Components**

In 2025 approximately 91% of our CEO's target total compensation and 87% of the other Named Executive Officers' (NEOs) target total compensation (in both cases excluding employee benefits and perquisites) was variable and dependent on Corning's financial performance or stock price.

| **Our Metrics and Why We Use Them** |  |
| &nbsp;&nbsp;**Core Earnings per Share (Core EPS)**<br> Core EPS is our key measure of **profitability**.\*<br> **Core Net Sales**<br> Growing **core net sales** — both organically through innovation and through acquisitions — remains critical to our **short**- and **long**-term success. | &nbsp;&nbsp;**Adjusted Free Cash Flow**<br> Strong cash generation enables us to **invest in future growth, sustain leadership in our markets, and remain financially strong during periods of uncertainty**. It also requires us to carefully manage our capital investments.<br> **Return on Invested Capital (ROIC)\*\***<br> 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 and Performance Stock Units (PSUs) earned are increased or decreased up to 10% based on Corning's ROIC improvement over the three-year performance period. |

---

\*Corning budgets for share repurchases when establishing annual financial performance targets.

\*\*ROIC as used here and elsewhere in our compensation discussion refers to ROIC for compensation purposes, which is a different metric from core ROIC. Please see the bottom of page 69 and Appendix A for more information.

**Core net sales is a primary indicator of Corning's short- and long-term success.** Evaluating performance against a predetermined net sales metric provides insight into how well the Company has retained sales and met sales growth targets, accounting for both organic growth efforts and the impact of acquisitions. We use core net sales as a performance measure in our annual bonus plans (GoalSharing and PIP) because GoalSharing impacts every employee and PIP impacts over 8,000 employees. In this way, every employee has alignment with Corning's sales growth goals. The LTI plan, which impacts approximately 320 executives who are key to driving the short- and long-term financial growth of the Company, also includes a core net sales performance measure. Incorporating net sales into both the STI and LTI plans allows for a comprehensive evaluation of Corning's ability to establish sustainable sales growth. It is a "duplicate goal" for only a small fraction, about 0.5%, of our approximately 67,200 employees, and **the Compensation and Talent Management Committee believes the increased focus on core net sales growth is appropriate for that smaller group of executives given the importance of sales growth for Corning over time and the essential role of these key executives in facilitating and driving this sales growth.**

**Restricted Stock Units**

In addition to the performance metric-driven compensation described above, 30% of each executive's target Long-Term Incentive award is delivered in the form of time-based Restricted Stock Units (RSUs) that will vest after three years. These RSUs are not tied to specific performance measures; however their value is directly impacted by changes in the Company's stock price. The impact of our stock price, along with the three-year vesting period, help to further align the compensation of our executives with the performance outcomes of our shareholders and also provide an ongoing retention benefit for executives, in particular with respect to those executives who are not yet retirement-eligible.

Proxy Statement Summary

Impact of our Values in Action

Corning is guided by its core Values, which define our relationship with our stakeholders. These Values – Quality, Integrity, Performance, Leadership, Innovation, Independence and The Individual – are the foundation of who we are. Our Values guide our actions and decisions, as they have for much of our 175-year history. We are always working to leave the world better than we found it. That's why we lead with our Values, whether in the products we make, the way we make them, or how we treat people and our communities. We believe that our innovations have transformed industries, enhanced people's lives and addressed some of society's biggest challenges. In accordance with our Values, we also believe improved, sustainable business practices increase shareholder value, drive performance, strengthen our Company, increase our connection with our shareholders, and help us better serve our customers and the communities in which our employees live and we operate. **We embrace these opportunities to deliver value to our shareholders, our employees, our customers, and the wider world.**

At Corning, we think about our sustainability contributions in two categories: **Our handprint** – what we enable others to do through our products and services, and **our footprint** – how our actions directly affect others. Our people and products make a positive difference in the world, and continuous innovation, done our way, is made sustainable through a deeply engrained moral compass and the trust of our stakeholders.

| **HANDPRINT**<br> ![](glw4500541-def14a1x19x1.jpg) | • **Harnessing solar power with a resilient U.S. supply chain.** Coming online in 2025, Corning now operates the largest ingot and wafer facility in the United States, delivering secure and transparent solutions that meet rising global energy demand. With a co-located polysilicon source on our Michigan campus, our logistics are measured in minutes, not months, making us resilient to trade disruptions and reducing transportation-related emissions.<br> • **Making AI more sustainable.** With the rise of AI comes an unprecedented demand for energy from data centers and hyperscaler facilities. Corning<sup>®</sup> GlassWorks AI™ Solutions, offer a portfolio of products and services to help operators build the dense fiber infrastructure required for data center connectivity. Greater density means more fiber in the same footprint, resulting in a more efficient use of materials. A central product in the portfolio, Contour™ Flow cable, fits double the optical fiber into the same space, allowing operators of intercity networks to reuse existing infrastructure.<br> • **Using co-packaged optics to promote data center efficiency.** The rise of AI has pushed copper connections in data centers to their limit – creating computational bottlenecks and generating extra heat. Corning's co-packaged optics technology increases optical fiber's reach into the server, keeping the data in its optical form until it gets much closer to the GPU or switch. This helps to unlock faster, cheaper, and more energy-efficient data processing.<br> • **Helping to make windows less wasteful.** Corning is vital in the push for building energy efficiency with our solution for triple- and quadruple-paned windows. Corning<sup>®</sup> Enlighten™ Glass is an enabling technology for high-performance windows and doors that can significantly enhance the thermal performance, comfort, durability, and aesthetics of built environments. |
| **FOOTPRINT**<br> ![](glw4500541-def14a1x19x2.jpg) | • **Reworking our packaging to reduce waste.** Our Optical Communications business eliminated the use of LDPE polybags to hold coiled cable trunks in boxes by 50% for EMEA data center customers, and eliminated the use of foam inserts for Edge XD, resulting in a reduction of 1 ton of CO<sub>2</sub> in EMEA. Additionally, the business achieved a 52% reduction in plastic corrugate reels packaging in NAFTA and EMEA.<br> • **Encouraging self-ownership of sustainable process improvements.** Competing teams from the Corning Sustainability Network pitched ideas for sustainability projects to raise awareness of innovative process improvements and receive funding for implementation. Researchers from Corning Research Center China in Shanghai won $20,000 to use scrap materials as an energy storage solution, while a team from Corning European Technology Center in France won $5,000 to greatly improve the energy efficiency of their furnaces with new technology.<br> • **Broadening our sources of power.** In 2025, we expanded the scope of our solar energy supply, including beginning to receive energy from ib vogt's solar farm in Segovia, Spain, through renewable energy credits and installing solar power panels to supply power for nonprocess equipment at our optical fiber plan in Haikou, China, generating an estimated annual energy savings of 788,000 kWh/year. |

Corporate Governance and the Board of Directors

Board Leadership Structure

Our Board leadership structure combines the roles of Chairman and Chief Executive Officer, held by Mr. Wendell P. Weeks, with a Lead Independent Director, Dr. Stephanie A. Burns, and independent committee chairs. Each year, the Board reviews whether this structure continues to serve the best interests of the Company and its shareholders. In February 2026, after conducting that review, the Board unanimously determined that this structure remains the most effective model for Corning.

**The Value of Unified Leadership Under Mr. Weeks**

The Board believes that combining the Chairman and CEO roles under Mr. Weeks creates meaningful strategic and operational benefits that drive value creation and align with shareholder interests. With more than 40 years at Corning, Mr. Weeks brings vast knowledge of the Company's diverse businesses, global operations, innovation pipeline, and competitive landscape. His dual role enables him to bridge Board-level strategy and day-to-day execution seamlessly, ensuring that the priorities set in the boardroom translate directly into operational results. It also allows Corning to speak with a single, consistent voice to shareholders, customers, employees, and other stakeholders, a significant advantage in an increasingly complex business environment.

**Strong Independent Oversight Led by Dr. Burns**

This unified leadership is balanced by rigorous independent oversight. As Lead Independent Director, Dr. Burns draws on her experience as former CEO of Dow Corning and her deep technical expertise to lead the independent directors with authority and effectiveness. Together with our independent committee chairs, she ensures that the Board exercises substantive, ongoing oversight of management and Company performance. This independent leadership is reinforced by Corning's comprehensive set of shareholder-focused corporate governance practices and policies.

**A Track Record That Validates the Approach**

The strength of this structure is reflected in results. Under the current leadership framework, Corning has delivered total shareholder returns that significantly exceed those of our industry peers, demonstrating that unified leadership and engaged independent oversight, working together, create tangible value for shareholders.

**A Commitment to Flexibility and Ongoing Evaluation**

The Board recognizes that no single leadership model is right for all companies or all circumstances. Our Corporate Governance Guidelines deliberately preserve the Board's flexibility to adopt the structure that best serves shareholders at each stage of the Company's evolution. In its annual review, the Board considers a range of factors, including the Company's strategic priorities and business needs, the composition of the Board and senior management, leadership continuity, and sound succession planning. This disciplined process ensures that the Board's leadership structure is never static, but is instead regularly evaluated and affirmed or adjusted based on current conditions.

The Board believes that Corning's current leadership structure, unified strategic direction through Mr. Weeks' combined Chairman and CEO role, paired with the strong independent oversight provided by Dr. Burns and our independent committee chairs, is the structure best positioned to oversee strategic matters and drive long-term value for our shareholders.

Her background spans global scientific innovation, manufacturing, and commercial management, complemented by service on other public boards.

Board Composition and Refreshment

Our Board is responsible for the oversight and success of our Company. We believe that our Board operates most effectively by leveraging its broad range of experience, skills, and knowledge to understand the risks and opportunities of, our short-, medium-, and long-term strategies. As such, our Board seeks to implement a dynamic boardroom culture that encourages independent thought as well as intelligent debate on critical matters to achieve a higher level of success for the Company and our investors. To achieve this result, we seek to maintain a mix of directors who bring strong leadership, distinct perspectives, and a broad range of skills and depth of experience aligned with the Company's strategic priorities. A supermajority of independent directors ensures robust debate and challenged opinions in the boardroom, while a range of perspectives and expertise contributes to a wide range of views.

Ongoing Board Refreshment

Continuing to successfully execute on our ongoing Board refreshment strategy remains a key priority for our Board. We believe that aligning the skills and competencies of our Board with the Company's strategic priorities maximizes value for our shareholders.

CORNING 2026 PROXY STATEMENT 37

[**Table of Contents**](#toc)

Corporate Governance and the Board of Directors

Our Board seeks to operate with the highest degree of effectiveness, providing dynamic oversight of the Company's evolving strategies and continued growth arc, and believes a deeply experienced and multidimensional board enhances decision-making, ensuring the widest range of opinions and viewpoints are expressed in the boardroom. To this end, the Board seeks highly qualified candidates with varied backgrounds, skills and experiences, including appropriate financial, industry and other expertise relevant to the Company's business and strategy, in accordance with its Corporate Governance Guidelines. The Board also believes it is desirable to maintain a mix of longer-tenured, experienced directors that have developed increased knowledge and insight into the Company's operations, and newer directors with fresh perspectives and new ideas, and will take this into consideration as part of its refreshment efforts.

As part of our broader refreshment efforts, Dr. Stephanie A. Burns was appointed Lead Independent Director by the independent directors of the Board effective May 2, 2024 and continues to serve in the role. Most recently, on February 11, 2026, Dr. Burns was reappointed as Lead Independent Director by the independent directors of the Board as a result of our Board's annual review process. As described in more detail beginning on page 34, Dr. Burns' strong and productive working relationships with her fellow directors and her dynamic experience and leadership has enhanced Board oversight, decision-making, and engagement during her tenure. Additionally, the Board recently refreshed its committee membership and leadership roles, including the Board's appointment of new chairs of the Compensation and Talent Management Committee, Nominating and Corporate Governance Committee, and Audit Committee. These new chairs have brought fresh perspectives and insights to the committees they lead.

In 2025, as part of this ongoing effort to maintain a vital and engaged boardroom today and into the future, the Board welcomed Ami Badani as its newest director. Ms. Badani is recognized for her leadership at the intersection of AI, semiconductors, go-to-market strategy, and business transformation. The Board believes that her expertise in strategic marketing, portfolio expansion and the scaling of transformative technologies aligns with Corning's longstanding commitment to deliver innovations that serve and shape vital industries. Her impressive combination of skills, experiences and personal qualities will serve our shareholders, the Company and our Board well now and in the years ahead.

With the addition of Ms. Badani, **we have added four new independent directors in the last five years, with seven director retirements over the last two years**, bringing our Board size to 10 directors. Consistent with the Board's broader assessment of its focus and alignment with our strategic needs, the Nominating and Corporate Governance Committee has determined the appropriate Board size for our Company is between 9 and 12 directors. The Committee prioritizes decision-making efficiency, ease of communication, and the capacity to focus on strategic oversight matters in determining optimal board size. The Committee will continue to weigh these factors as it continues to evaluate additional highly qualified, multifaceted candidates pursuant to the Committee's robust assessment process and criteria further described below.

Considerations for Nomination or Re-nomination

Our Nominating and Corporate Governance Committee appreciates the importance of critically evaluating individual directors and their contributions to our Board both when identifying new director candidates and in connection with annual re-nomination decisions. Annual Board and director self-assessments are utilized both to help identify skills and experiences sought in future candidates and as determinants in a director's re-nomination and tenure. All incumbent director nominees complete questionnaires annually to update and confirm their background, qualifications and skills, and to identify any potential conflicts of interest.

When identifying prospective director nominees or making re-nomination decisions, the Nominating and Corporate Governance Committee considers those factors most relevant to the Company's needs and also considers each individual in the context of the Board's composition as a whole, with the objective of recruiting and recommending a slate of director nominees who can best sustain the Company's success and represent shareholders' interests through sound judgment and informed decision-making aligned with our strategic priorities. Key factors include relevant knowledge and experience, range of background and experience, and expertise in certain strategic skills and core competencies, including public company governance experience, finance and accounting acumen, enterprise and emerging risk management experience, government and regulatory experience, experience in management of a complex organization, knowledge of our industries and end markets, experience in technology, R&D, and innovation, knowledge of operations, commercial strategy experience, enterprise and digital transformation experience, corporate development experience, and a global perspective. The Committee also

Corporate Governance and the Board of Directors

assesses personal qualities of leadership, character, candor, judgment, analytical skills, ethics and reputation, willingness to engage management and other board members in a constructive and collaborative fashion, and the ability to act on behalf of shareholders.

While the Board believes director participation on other public company boards adds additional depth to our governance and risk oversight practices, the Board also expects that a director's other commitments will not interfere with his or her duties as a Company director. The Nominating and Corporate Governance Committee assesses directors' time commitment to the Board throughout the year, including through the annual formal self-evaluation process and prior to the annual renomination of currently serving directors. The Nominating and Corporate Governance Committee and the Board take into account the nature and extent of a director's other commitments when determining whether to nominate that individual for election or re-election. Under the Company's Corporate Governance Guidelines, absent review and approval by the Nominating and Corporate Governance Committee, non-employee directors should not serve on more than three public company boards in addition to the Company's Board (for a total of four public company boards), and an employee director should not serve on more than two public company boards in addition to the Company's Board (for a total of three public company boards).

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 retains one or more executive search firms to help identify director prospects, perform candidate outreach, assist in reference and background checks, and provide other related services.

Corporate Governance and the Board of Directors

Director candidates recommended by shareholders in the manner described beginning on page 105 will be considered in the same way 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 "Shareholder Proposals and Director Nominations for the 2027 Annual Meeting" on page 105 of this proxy statement.

![](glw4500541-def14a1x42x1.jpg)

Director Independence

Our Corporate Governance Guidelines require a majority of our directors to be independent. **Currently, the Board is comprised solely of independent directors other than the CEO (90%), and 100 percent of the Audit, Compensation and Talent Management, Finance, Information Technology and Nominating and Corporate Governance Committee members are independent**. 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 2023 between Corning and entities associated with our independent directors or members of their immediate family. The Board also reviewed information about each director's business and personal activities as they may relate to Corning and Corning's management. It considered that each of Ms. Badani, Mr. Brun, Mr. Ferguson, Dr. Huttenlocher, and Mr. Martin are or were, during the previous three years, an employee, partner or affiliate 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

Corporate Governance and the Board of Directors

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 arose only from such director's position as an employee, partner or affiliate 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.

Based on all 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 written policy requiring the full Board or a designated Board committee to pre-approve 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. As set forth in the Corporate Governance Guidelines, 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 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 or approval of any transaction if he or she, or his or her immediate family member, has a direct or indirect material interest in the transaction. No related party transaction occurred in 2025 that required disclosure under this policy or under relevant SEC rules.

Compensation and Talent Management Committee Interlocks and Insider Participation

Dr. Burns, Mr. Brun, Mr. Ferguson, and Mr. Martin, as well as one director, Dr. Rieman, who retired effective May 1, 2025, served on the Compensation and Talent Management Committee during 2025. No member of the Compensation and Talent Management Committee that served during 2025 is now, or has ever been, an officer or employee of Corning. No member of the Compensation and Talent Management Committee had any relationship with Corning or any of its subsidiaries during 2025 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 2025 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 and Talent Management Committee.

Corporate Governance and the Board of Directors

Our Board's Role and Responsibilities

Our Board bears the responsibility for the oversight of the Company and its management team on behalf of our shareholders in order to ensure long-term value creation. In that regard, the primary responsibilities of our Board include, but are not limited to (i) oversight of the Company's corporate strategy, including strategic objectives for the Company's businesses, (ii) ongoing succession planning and talent management, and (iii) oversight of risk management, including overseeing the development of the Company's risk appetite. The Board fulfills these responsibilities through its committees as well as with direct oversight of management. This approach allows the Board to draw upon the experience and judgment of all directors in understanding and overseeing the Company's risks and opportunities.

Oversight of Corporate Strategy

One of the Board's foremost responsibilities is overseeing management's establishment and execution of its corporate strategy. At least annually, management reviews the overall corporate strategy and key strategic risks with the Board. Throughout the year, the Board monitors progress against the strategic plan to ensure alignment with long-term objectives. Our senior management team regularly reviews developments, including operational and financial performance, against the Company's strategic framework at Board meetings and provides updates between regularly-scheduled sessions, as necessary.

Management Succession Planning

Our Board ensures that Corning has the right management team in place to pursue our strategies successfully. The entire Board oversees management succession planning, with our Lead Independent Director facilitating ongoing review and with Board approval of succession and management development plans for the CEO and senior management. The goal of this ongoing process is to maximize the pool of internal candidates able to assume top management positions with minimal business interruption. **At every meeting, the Board discusses succession planning for the Chief Executive Officer and 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.

Succession planning remains a cornerstone of the Board's governance oversight, resulting in the elevation of highly qualified leaders to key executive roles, including the appointments of internal candidates as Chief Financial Officer, Chief Technology Officer, and Chief Human Resources Officer, and accomplished external candidates as Chief Digital and Information Officer and Senior Vice President and General Counsel. In early 2025, we announced the retirement of our long-time President and Chief Operating Officer, Eric Musser, and the appointment of A. Hal Nelson III as Executive Vice President and Chief Operating Officer, which was part of a long-term succession planning process that helped facilitate an orderly and successful transition. Further, the Board appointed Lewis A. Steverson as Vice Chairman in addition to his responsibilities as Executive Vice President and Chief Legal and Administrative Officer, and John Z. Zhang as Executive Vice President and Chief Corporate Development Officer, expanding his leadership of our Display, Specialty Materials, and Life Sciences businesses. These actions underscore the Board's proactive approach to talent development and succession, leveraging Corning's deep leadership bench to ensure continuity, operational excellence, and sustained value creation for our customers, shareholders, and broader stakeholder community.

Workforce Management

Corning's talented and dedicated workforce of approximately 67,200 full-time employees is central to our success, and the Board is committed to fostering a workplace culture rooted in our core Values, where every individual is respected, valued, recognized, and supported. The Compensation and Talent Management Committee provides consistent oversight of employee development, compensation, and talent management programs, ensuring alignment with our strategic objectives and commitment to attracting, retaining, and developing top talent. As part of our robust governance practices, the Committee also reviews the detailed results of our Voice to Action Survey, which gives employees an important platform to share feedback on leadership, engagement, work environment, risk management, career growth, and well-being. Last year, more than 88% of employees participated in the survey, contributing to an impressive three percentage point increase in engagement compared to the prior year and reaffirming our ongoing commitment to understanding and responding to the needs and aspirations of our workforce in support of long-term value creation for our stakeholders.

Corporate Governance and the Board of Directors

We prioritize the well-being of our people, and our Total Rewards package includes a range of offerings designed to support the health, wealth, and growth of our employees, including comprehensive healthcare and wellness programs, competitive salaries and retirement plans, and opportunities for professional development. We employ people at all career stages with varied backgrounds and we invest in the further development of our employees through training, apprenticeship programs, leadership development plans and tuition assistance among other professional development programs and practices. Last year, more than 20,000 employees participated in our Leadership Essentials training program, and numerous employees participated in regional mentorship programs. We believe this employee development makes us more competitive and assists with leadership succession planning throughout the Company.

Risk Oversight

Inherent in the Board's responsibilities is the understanding and oversight of the various risks facing the Company. The Board does not view risk in isolation: risks are considered in virtually every decision. The Board recognizes that it is neither possible nor prudent to eliminate all risk; indeed, purposeful and appropriate risk taking is essential for the Company to be competitive on a global basis and to achieve the Company's long-term strategic objectives.

Effective risk oversight is of critical importance to our Board. The Board has implemented a risk governance framework designed to:

• understand critical risks in the Company's business and strategy;

• allocate responsibilities for risk oversight among the full Board and its committees;

• evaluate the Company's risk management processes and whether they are functioning adequately;

• facilitate open communication between management and Directors; and

• foster an appropriate culture of integrity and risk awareness.

To learn more about key risks facing the Company, you can review Part I, "Item 1A. Risk Factors" in our Annual Report on Form 10-K. The risks described in our Annual Report on Form 10-K are not the only risks facing the Company. Additional risks and uncertainties not currently known or that may currently be deemed to be immaterial based on the information known to the Company also may materially adversely affect the Company's business, financial condition or results of operations in future periods.

Risks associated with current business status or strategic alternatives, including traditional enterprise risk as well as newly emerging and evolving risks, are subjected to analysis, discussion and deliberation by management and the Board. Operationally, management reports periodically to the Board on the Company's enterprise risk management (ERM) policies and procedures, and to the Audit, Information Technology, and Finance Committees on our top risks and compliance policies and practices. Management also provides a comprehensive annual report of top risks to the Board. The Chief Compliance Officer reports to the Audit Committee at each of its meetings on any relevant compliance issues, and annually presents an overview of the Company's compliance function, processes and effectiveness. While these periodic reports provide the Board with a regular comprehensive perspective of our key enterprise risks, specific risks are highlighted and discussed in connection with each matter brought to the Board or its committees in the ordinary course.

Corning's ERM program utilizes (1) a Risk Council chaired by our 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

44 CORNING 2026 PROXY STATEMENT

[**Table of Contents**](#toc)

Corporate Governance and the Board of Directors

Council, which reports regularly to the Audit Committee and reviews the Company's compliance with laws and regulations of the countries in which we conduct business as well as disclosures made by the Company about relevant risks.

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.

Cybersecurity

Corning's Board oversees risks associated with cybersecurity threats. In particular, the Information Technology Committee of the Board is responsible for cybersecurity governance and has information security oversight as a key component of its charter. In all meetings, the IT Committee reviews the Company's cybersecurity posture as well as any significant cybersecurity events. Corning's Chief Digital and Information Officer (CDIO), in combination with Corning's Chief Information Security Officer (CISO), briefs the IT Committee on cybersecurity activities and long-term cybersecurity strategies, as well as general cybersecurity trends that could have a material impact on the Company. On an annual basis, the CISO provides a cybersecurity update to the Board and participates in meetings with the IT Committee and Audit Committee to review significant cybersecurity trends, risks and their related impacts, if any, on internal controls. At any time, Board members may raise concerns regarding the Company's cybersecurity posture and recommend future changes to controls or procedures. The Company utilizes a multi-faceted information security training program for all employees. This includes a mandatory annual training as well as monthly, quarterly, and yearly deliverables and touch points uniquely crafted for certain groups of employees based on their roles and the specific security risks they face. Should a cybersecurity incident rise to the level of a corporate crisis, consistent with the Company's corporate crisis response escalation protocols, the Board would be engaged.

Artificial Intelligence

Our Board and management team understand the business of technology and have experience driving innovation and product development, and believe that AI carries significant opportunity and risk for the Company and the world. As such, our Board oversees the Company's governance of AI and related risks, including the use of AI for scientific discovery, research and development, manufacturing, and other applications. Monitoring AI risk and effectiveness is one of the primary responsibilities of the Information Technology Committee, which is composed of Board members who provide significant experience in computer science, AI, and enterprise digital transformation. Senior leadership, including the CDIO, further discuss relevant aspects of our AI strategy regularly with the Board. In 2023, we introduced an Artificial Intelligence and Machine Learning Policy for the Company and our employees around the globe. The policy outlines standards to help employees access and use AI and machine learning technology in a way that is safe and secure, and aligns with Corning's Code of Conduct, Values, and other policies.

Government Affairs

Corning participates in public policy advocacy at the state federal, and international levels as a component of responsible business conduct. The Board recognizes that involvement in legislative, regulatory, and political processes is an important way to uphold our Values, support sound public policy, foster market innovation, promote fiscal responsibility, and maintain a constructive regulatory environment for our industries. The Nominating and Corporate Governance Committee has primary oversight of Corning's political contributions and related activities. Our Senior Vice President, Government Affairs, along with other senior management, reports regularly to the Committee and the Board regarding the Company's political activities, to ensure appropriate risk assessment, management, and oversight. For more information regarding our policies and disclosures with respect to political activity, please refer to page 48.

Sustainability

The Board believes that identifying risks and opportunities relating to sustainability is essential to the long-term viability of our Company and to deliver long-term value to shareholders. With respect to Board oversight of sustainability matters, our Board believes each committee of the Board should maintain oversight over the matters that fall within its scope. Our Nominating and Corporate Governance Committee provides primary oversight of general sustainability matters, including environmental and climate-related, social and governance matters, while our Compensation and Talent Management

CORNING 2026 PROXY STATEMENT 45

[**Table of Contents**](#toc)

Corporate Governance and the Board of Directors

Committee oversees human capital management and culture matters, and other committees oversee sustainability matters that fall within their scope. The relevant Committees then report to the Board as appropriate. Using this approach, members of each committee can leverage their subject-matter expertise to oversee and advise the Board on matters most relevant to their committee's area of responsibility. Our Vice President of Sustainability and Climate Initiatives, reporting to our Executive Vice President and Chief Financial Officer, has primary accountability for our sustainability strategy, performance and disclosures. These matters are managed through coordination of a cross-disciplinary team of senior corporate leaders. Our business leaders are responsible for implementing Corning's sustainability efforts throughout their respective businesses, and employees can join our Sustainability Network, whereby they can make individual efforts in their communities and areas of activity.

Beyond the Boardroom

The commitment of our Board extends well beyond preparation for, and participation at, regularly scheduled Board or committee meetings. Engagement outside of meetings provides our directors with additional insight into our business and our industry and gives them valuable perspectives on the performance of our Company, the Board, our CEO and other members of senior management, as well as on the Company's culture and strategic direction.

Compensation Risk Analysis

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

Annually, the Compensation and Talent Management Committee instructs Frederic W. Cook & Co., Inc. (FW Cook), the committee's independent consultant, to undertake a risk assessment regarding the Company's compensation policies and practices covering all employees, and reviews the this risk assessment each year in February. As part of its review, the 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 pay-outs 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 local plant 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;

• Internal advisory committees and plan caps that are intended to avoid imprudent risk-taking;

• 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 Compensation and Talent Management Committee approval of all officer and equity compensation; and

• Immediate oversight of executive pay matters in mergers and acquisitions and unit compensation plans throughout the acquisition integration process and/or until fully integrated.

With the assistance of the annual risk assessment provided by FW Cook, the Compensation and Talent Management Committee concluded that Corning's executive compensation program is balanced and does not reward inappropriate risk-taking.

Board and Shareholder Meeting Attendance

The Board of Directors met six times in 2025. **Attendance at Board and committee meetings averaged 97% in 2025**, and each incumbent director nominee attended 100% 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 of Shareholders, absent extraordinary circumstances. All then-serving directors attended our 2025 Annual Meeting of Shareholders.

Ethics and Conduct

We are committed to conducting business lawfully and ethically. Our directors, executive officers, and all Corning employees must act 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. Furthermore, our Code of Ethics for our Chief Executive Officer and Financial Executives requires business integrity, avoidance of conflicts of interest, and transparency. 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.

Corporate Governance and the Board of Directors

Director Compensation

The Compensation and Talent Management Committee sets director compensation at levels that ensure our directors are paid competitively for their time commitment and responsibilities relative to directors at companies of comparable size, industry and scope of operations. The Compensation and Talent Management 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. In addition to our objective to pay competitively we also intend for a significant portion of director compensation to be stock-based. The Compensation and Talent Management Committee's independent consultant, FW Cook, conducts an annual review of the director compensation levels relative to our objectives, external best practices as well as 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 and cash compensation for its directors. Corning believes that a significant portion of director compensation should be linked to the Company's performance over time. Therefore, a significant portion of the directors' compensation is paid as an annual equity grant of restricted stock units (in 2025, 2.1x the annual cash retainer), which are not settled in shares of common stock until retirement or resignation from the Board, unless the director makes an election prior to the start of the calendar year to receive the RSUs either 1 year, 5 years, or 10 years after the grant date (subject to the Share Ownership Guidelines for directors).

Directors may defer receipt of all or a portion of their cash compensation and may defer receipt of their annual equity retainer (in RSUs) by electing distribution in up to 10 annual installments. 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.

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.

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

**The following table outlines 2025 director compensation:**

Corporate Governance and the Board of Directors

Changes to Director Compensation in 2026

In February 2026, the Board approved certain changes to director compensation proposed by the Compensation and Talent Management Committee in consultation with the committee's independent consultant in order to remain competitive. Specifically, the non-employee directors' annual equity grant increased from $235,000 to $240,000 and the annual cash retainer increased from $110,000 to $115,000. Additionally, the annual retainer for the Lead Independent Director was increased from $40,000 to $50,000 and the annual retainer for the Chair of the Audit Committee was increased from $25,000 to $30,000.

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 up to $1,000,000 (employee directors) or $1,250,000 (non-employee directors) following his or her death. This program is directly funded from general corporate assets. Because the charitable deductions 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. Dr. Burns, Mr. Cummings, Dr. Huttenlocher, and Mr. Martin each remain eligible for this discontinued program.

Directors are also eligible to participate in the Corning Impact and Investment Matching Gifts Program for eligible charitable organizations. This program is available to all active Corning employees and directors. In 2025, the matching gift amount available on behalf of each participant in the program was $7,500 per calendar year.

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

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 non-employee directors, named executive officers (NEOs), and non-NEO senior leadership team members 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. All directors and NEOs who have been so for five years or more currently comply with the guidelines.

Our directors and executive management are also subject to our anti-hedging and anti-pledging policies. For further information, see "Anti-Hedging Policy" and "Anti-Pledging Policy" on pages 75 and 76, respectively.

Delinquent Section 16(a) Reports

SEC rules require disclosure of those directors, officers, and beneficial owners of more than 10% of our common stock who fail to timely file reports required by Section 16(a) of the Securities Exchange Act of 1934 (Exchange Act) during the most recent fiscal year. Based on review of reports furnished to us and written representations that no other reports were required during the fiscal year ended December 31, 2025, all Section 16(a) filing requirements were met, except that one Form 4 for Wendell P. Weeks, covering the disposition of 24,322 shares of common stock, was not timely filed due to an inadvertent administrative error and not any error of the reporting person.

(3) Includes shares of common stock held by The Bank of New York Mellon Corporation as the trustee of Corning's Investment Plans for the benefit of the members of the group, who may instruct the trustee as to the voting of such shares. If no instructions are received, the trustee votes the shares in the same proportion as it votes the shares for which instructions were received. The power to dispose of shares of common stock is also restricted by the provisions of the plans. The trustee holds for the benefit of Weeks, Schlesinger, Musser, Nelson, Steverson and Zhang, and all executive officers as a group, the equivalent of 15,114; 0; 0; 4,944; 0; 0; and 23,401 shares of common stock, respectively. It also holds for the benefit of all employees who participate in the plans the equivalent of 5,565,018 shares of common stock (being .65% of the class).

(4) The Restricted Stock Units (RSUs) and Performance Share Units (PSUs) represented entitled the holder to receive the same number of unrestricted shares of common stock upon the lapse of restrictions, at which point shareholders will have sole investment and voting power. RSUs and PSUs that will not vest within 60 days of the date of this table are not considered beneficially owned for purposes of the table and therefore are not included in the Total Shares Beneficially Owned column because the holders are not entitled to voting rights or investment control until the restrictions lapse. However, ownership of these RSUs and PSUs further aligns our Directors and Executive Officers' interests with those of our shareholders.

Proposal 2: Approve, on an Advisory Basis, Our Executive Compensation (Say on Pay Proposal)

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 (the "Exchange Act"), as disclosed in this proxy statement, which includes the Compensation Discussion and Analysis, the compensation tables 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.

Our Board maintains a "pay for performance" philosophy that forms the foundation for all Compensation and Talent Management Committee 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 and Talent Management Committee has made under those programs during the last year and the factors considered in making those decisions. Overall, our shareholders have affirmed their support of our executive pay 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 unanimously 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 compensation tables and related narrative disclosure on executive compensation) is hereby APPROVED.

Compensation Discussion & Analysis

**2025 Target Compensation Summary**

Target compensation for all NEOs rose year over year, reflecting both Corning's outstanding performance in 2024 and our sustained growth trajectory. Throughout the year, Corning reinforced its position as a global leader in advanced optical and materials solutions, critical to the explosive expansion of AI infrastructure around the world. We delivered record results in Optical Communications and Specialty Materials, expanded into semiconductor and solar glass innovations, and increased investments in manufacturing capacity and automation. Most notably, our total shareholder return (TSR) significantly outpaced the S&P 500, S&P Equal Weight, and our Compensation Peer Group. In recognition of our key executives' pivotal contributions to these achievements, and in light of the momentum generated by the successful execution of our Springboard plan, the Compensation and Talent Management Committee determined that increased compensation was both warranted and appropriate.

In the case of the long-term incentive (LTI) targets for Mr. Weeks, Mr. Musser and Mr. Steverson, the Committee also took into consideration that the LTI targets for these executives had not been increased since 2022. The target compensation for Mr. Schlesinger, Mr. Nelson, Mr. Steverson and Mr. Zhang were further adjusted in an effort to align their compensation with their increased responsibilities and to more closely align the targets with external market benchmarks. In early 2025, Mr. Nelson, Mr. Steverson, and Mr. Zhang each were promoted into roles with enhanced responsibilities: Mr. Nelson as Executive Vice President and Chief Operating Officer, Mr. Zhang as Executive Vice President and Chief Corporate Development Officer, expanding his leadership of our Display, Specialty Materials, and Life Sciences businesses, and Mr. Steverson as Vice Chairman in addition to his responsibilities as Executive Vice President and Chief Legal and Administrative Officer. While Mr. Schlesinger's appointment predates these more recent succession actions, the decision to increase his compensation was part of a multi-year plan closely align his compensation with the benchmark targets of similarly scoped chief financial officers.

The following 2025 Target Compensation Table reflects the Compensation and Talent Management Committee's compensation decisions for our NEOs for levels of base salary, target bonus opportunity and target value for long-term incentive awards made during 2025, in the manner in which it was considered by the Committee. While this table summarizes how the Compensation Committee viewed its annual target compensation decisions for the NEOs, it is not a substitute for the Summary Compensation Table on page 77.

This presentation in the 2025 Target Compensation Table above differs from that shown in the Summary Compensation Table in the following respects:

&nbsp;&nbsp;&nbsp;&nbsp;• **Base Salary:** The
 table above reflects the annual base salary rate applicable for each NEO approved by the Committee. The "Salary" column
 in the Summary Compensation Table presents the amount of base salary actually paid during 2025.

[**Table of Contents**](#toc)

Compensation Discussion & Analysis

&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• **Target STI:** The
 table above reflects the target cash incentive award opportunity (which includes both target Performance Incentive Plan and GoalSharing
 opportunities) for each NEO. The "Non-Equity Incentive Plan Compensation" column in the Summary Compensation Table includes
 the actual cash incentive earned based on 2025 performance (to be paid in the first quarter of 2026).

• **Target LTI:** The
 "Target LTI" columns in the table above reflect the target grant date value of each NEO's long-term incentive awards
 during 2025, as approved by the Committee. Actual earned awards will depend on performance and/or stock price. The "Stock Awards"
 column of the Summary Compensation Table contains the grant value of the portion of 2023, 2024 and 2025 performance share units (PSUs)
 which are subject to 2025 performance, plus the grant date value of 2025 restricted stock units (RSUs), and the "Non-Equity
 Incentive Plan Compensation" column includes the actual earned value of the portion of 2023, 2024 and 2025 cash performance
 units (CPUs) which are subject to 2025 performance.

• **Target Total Direct Compensation:** The
 amounts disclosed in the table above differ from the amounts reported in the "Total" column of the Summary Compensation
 Table due to the different methodologies discussed in the notes above and below. Additionally, the table above excludes values reported
 in the "Change in Pension Value and Non-Qualified Deferred Compensation Earnings" and "All Other Compensation"
 columns of the Summary Compensation Table. Although important, these items do not comprise target direct compensation for internal
 and external benchmarking.

**Our Short-Term Incentives**

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

**Performance Incentive Plan (PIP)**

PIP recognizes and rewards leaders for delivering the annual operating plan. 2025 PIP for NEOs was based:

&nbsp;&nbsp;&nbsp;&nbsp;• 50% on corporate financial
 performance (of which, 75% was based on core EPS and 25% was based on core net sales)

• 50% based on business financial
 performance (of which, 25% was based on core net sales, 20% on core gross margin percentage, 30% on core net profit after tax, and
 25% on adjusted free cash flow, in each case, for the applicable division).

Our business financial performance targets are set both "bottoms up" by executive leadership within each division and "top down" by our corporate executive leadership, ensuring that division goals are carefully considered and assessed based on the realities of that division and the corporate strategic plan. For adjusted free cash flow, this includes an independent, forward-looking consideration of the division's cash flow needs for that year, including with respect to capital. Targets for core net sales, core net profit after tax, and core gross margin percentage may take into account new product introductions, anticipated customer growth, and expected pricing changes, among other unique considerations fundamental to that specific business. This process also considers relevant market factors, including the applicable market stage faced by the particular division in the coming year – a division facing a growth market is expected to take a different approach to its targets than one facing a declining or flat market. On top of these specific considerations, targets are also expected to drive each division to advance the Company's corporate goals. Since the launch of our corporate Springboard plan, each division's performance targets have been expected to contribute to Corning's broad Springboard goals – goals that we achieved in 2025, significantly ahead of plan.

As a result of this approach, in 2025:

&nbsp;&nbsp;&nbsp;&nbsp;• The 100% target goals
 for all but one division reflected year-over year growth from the division's 2024 actual results

• The maximum payout target goals for
 core net sales and core net profit after tax for all but one division reflected double digit growth from the division's 2024
 actual results

The business score for all NEOs (except Mr. Nelson and Mr. Zhang) is based on the average business financial performance across all of our operating divisions. The business scores for Mr. Nelson and Mr. Zhang are blended based on their respective responsibilities during 2025. Specifically, the first half average business financial performance of the

CORNING 2026 PROXY STATEMENT 57

Compensation Discussion & Analysis

operating divisions for which they were each responsible and the second half average business financial performance of all of our operating divisions. For 2026, the payouts for Mr. Nelson and Mr. Zhang will be based on the business financial performance of all of our operating divisions.

**GoalSharing**

GoalSharing plans are local unit annual performance plans (generally local plant or business unit) designed to give every employee the opportunity to be rewarded for achieving key local business unit objectives. Employee GoalSharing plans are weighted 75% on local unit performance metrics. These metrics typically include financial and/or continuous improvement objectives such as cost reduction, quality, or manufacturing performance. The remaining 25% reflects corporate financial performance.

For 2025, the GoalSharing payout for all NEOs except Mr. Nelson and Mr. Zhang was based on the average payout of all local unit plans. The GoalSharing payouts for Mr. Nelson and Mr. Zhang are a blended result based on their respective responsibilities during 2025. Specifically, the first half average results of the local unit plans for which they were each respectively responsible and the second half average results of all local unit plans. For 2026, the Goal Sharing payouts for Mr. Nelson and Mr. Zhang will be based on the average payout of all local unit plans.

Compensation Discussion & Analysis

**Our Long-Term Incentives**

We believe it is important that our long-term incentives (LTIs) drive the success of our strategic priorities and generate long-term value for our shareholders. We also believe it is important for a significant portion of our LTI awards to be in the form of equity to align our executives' financial interests with those of our shareholders.

LTI awards are comprised of:

&nbsp;&nbsp;&nbsp;&nbsp;• Performance Stock Units
 (PSUs) (45% of target LTI);

• Cash Performance Units
 (CPUs) (25% of target LTI); and

• Restricted Stock Units
 (RSUs) (30% of target LTI).

PSUs and CPUs pay out based on performance over a three-year period, while the RSUs vest after three years.

2025 CPU and PSU payouts will be based 70% on Adjusted Free Cash Flow, and 30% on Core Net Sales with annual results averaged over a three-year performance period (2025–2027). In addition, CPUs and PSUs are subject to an ROIC modifier of up to +/- 10%, based on a pre-established three-year ROIC improvement objective.

**Benefits and Perquisites**

To enhance our ability to attract and retain talented executive leaders we provide certain key benefits and perquisites detailed in the table below. These benefits and perquisites are determined in conjunction with our compensation philosophy and in consideration of other relevant factors, including that our corporate headquarters is not located near a major metropolitan center. The Compensation and Talent Management Committee regularly reviews the appropriateness and level of perquisites for the NEOs. See the discussion beginning on page 71 for more detail.

**2025 Performance Metrics**

Our key compensation metrics focus and align leadership on the key drivers for creating long-term value for our shareholders. In 2025, the Compensation Committee determined that core net sales, profitability (as measured by Core EPS) and a cash flow measure (as measured by adjusted free cash flow) were still the appropriate performance measures for 2025.

In addition to the performance metric-driven compensation described above, 30% of each executive's target Long-Term Incentive award is delivered in the form of time-based RSUs that will vest after three years. These RSUs are not tied to specific performance measures; however their value is impacted by changes in the Company's stock price. The impact of our stock price, along with the three-year vesting period, help to further align the compensation of our executives with the performance outcomes of our shareholders and provide an ongoing retention benefit for executives, in particular with respect to those executives who are not yet retirement-eligible.

Full-Year 2025: Achieving Milestones while Delivering Exceptional Results

For the full year 2025:

&nbsp;&nbsp;&nbsp;&nbsp;• We
 delivered double-digit core sales growth, and **delivered on our high-confidence Springboard sales plan a full year early.** 

• Core EPS grew twice as
 fast as sales, with full-year core results at $2.52.

• Adjusted free cash flow
 grew three times as fast as sales, reaching $1.72 billion for the full year, **nearly doubling since the launch of Springboard.** 

• We **expanded core operating margin by 180 basis points** year over year.

Additionally, in the fourth quarter of 2025, we delivered core operating margin of 20.2%, achieving our Springboard core operating margin target of 20% a full year early.

Taken as a whole, 2025 demonstrated the strong incrementals of our Springboard plan, with a greater than 20% core operating margin, core ROIC in the low teens, and stronger cash generation.

Overall, the first two years of Springboard have been a tremendous success—establishing a highly profitable launch point for future growth. With an upgraded high-confidence Springboard growth plan and long-term, de-risked contracts with major customers, Corning is well positioned to continue this momentum into 2026 and beyond, generating strong profit and cash flow as demand for our products and capabilities continues to grow.

\*Corning budgets for share repurchases when establishing annual financial performance targets.

\*\*Adjusted free cash flow goals are established yearly, independent of the prior year, as the Company's cash needs, including capital, will vary based on various strategic factors.

**Our Performance Metrics in Context**

In 2025, we again set rigorous performance metrics. The metrics we use to measure our performance continue to include core earnings per share (EPS), core net sales, and adjusted free cash flow, with a 3-year ROIC modifier on our LTI (see page 60 for details). These metrics and ROIC modifier were chosen because they are key drivers for creating long-term shareholder value and the financial indicators that best reflect the achievement of the strategic and operational objectives set out for our management team.

**Setting the Bar High in an Uncertain Environment**

Despite economic uncertainties and volatility in key end markets entering 2025, we deliberately set aggressive compensation **targets that exceeded our already strong 2024 performance:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Core EPS target of $2.26
 – a **15% increase** compared to 2024 actual results

• Core net sales target
 of $15.45 billion – a **nearly 7% increase** compared to 2024 actual results

• Adjusted free cash flow target
 of $1.40 billion – a **12% increase** compared to 2024 actual results

While our stock delivered exceptional 88% one-year TSR, we remained focused on the operational and financial metrics that drive sustainable value creation rather than stock price alone.

**Delivering Exceptional Results**

Corning exceeded the aggressive compensation targets it set for 2025. We emerged as the global leader in advanced optical and materials solutions critical to AI infrastructure expansion, expanded our reach in semiconductor and solar glass innovations, and increased investments in manufacturing capacity and automation, resulting in record financial results:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Double-digit sales growth** – delivering on our high-confidence Springboard sales plan a full year early

• **Core EPS of $2.52** –
 growing twice as fast as sales

• **Free cash flow of $1.72 billion** – growing
 three times faster than sales

**Our performance payouts exceeding 100% reflect our significant outperformance across all metrics.**

2025 Executive Compensation Program Details for NEOs

Compensation for all NEOs rose year over year, reflecting both Corning's outstanding performance and our sustained growth trajectory. Throughout the year, Corning reinforced its position as a global leader in advanced optical and materials solutions, critical to the explosive expansion of AI infrastructure around the world. We delivered record results in Optical Communications and Specialty Materials, expanded into semiconductor and solar glass innovations, and increased investments in manufacturing capacity and automation. Most notably, our total shareholder return (TSR) significantly outpaced the S&P 500, S&P Equal Weight, and our Compensation Peer Group. In recognition of our key executives' pivotal contributions to these achievements, and in light of the momentum generated by the successful execution of our Springboard plan, the Compensation and Talent Management Committee determined that increased compensation was both warranted and appropriate.

**Base Salary**

Base salaries provide a form of fixed compensation and are reviewed annually by the Compensation Committee, which considers internal equity and individual performance, as well as competitive positioning, as discussed in the "Compensation Peer Group" section beginning on page 73. In 2025, all of our NEOs except Mr. Nelson and Mr. Zhang each received base pay increases of 4-4.5%, respectively, in line with the annual salary increase budget for all U.S. salaried employees. Additionally, Mr. Schlesinger, Mr. Nelson and Mr. Zhang received higher than normal pay increases of 22%, 10%, and 10% respectively. These increases were, in part, an effort to align their compensation with their increased responsibilities and to more closely align the targets with external market benchmarks. As described further on page 54, in early 2025, Mr. Nelson and Mr. Zhang each were promoted into roles with enhanced responsibilities: Mr. Nelson as Executive Vice President and Chief Operating Officer and Mr. Zhang as Executive Vice President and Chief Corporate Development Officer, expanding his leadership of our Display, Specialty Materials, and Life Sciences businesses. While Mr. Schlesinger's appointment predates these more recent succession actions, the increase to his compensation likewise was in part a multi-year effort to more closely align his compensation with the benchmark targets of similarly scoped Chief Financial Officers.

Compensation Discussion & Analysis

**Short-Term Incentives**

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

**Performance Incentive Plan (PIP)**

PIP targets are established by the Compensation Committee each February as a percentage of the NEO's salary depending on the competitive marketplace and his or her level of experience. PIP payouts may be 0 to 200% of target, based on performance results.

In 2025, PIP targets (as a percentage of base salary) for our NEOs were increased as described below:

---

| | | |
|:---|:---|:---|
| **NEO** | **2024 PIP Target\*** | **2025 PIP Target\*** |
| Wendell P. Weeks | 150% | 160% |
| Edward A Schlesinger | 90% | 100% |
| Eric S. Musser | 140% | 140% |
| A. Hal Nelson III | 80% | 85% |
| Lewis A. Steverson | 95% | 100% |
| John Z. Zhang | 80% | 85% |

---

\* % of base salary

The increases to PIP targets shown above were in recognition of the contributions of these key executives to our strong 2024 results and the sustained momentum enabled by the successful execution of the Springboard plan as well as an effort to align certain NEO's compensation with the increased responsibilities associated with their respective appointments and external market benchmarks.

2025 PIP payout was 140% of target for all NEOs expect Mr. Nelson and Mr. Zhang, whose 2025 PIP payouts were 133% and 144%, respectively. Further details regarding the calculation of these payouts can be found beginning on page 57.

**GoalSharing**

GoalSharing is designed to motivate employees to work together to achieve the most critical goals in each local unit. All Corning employees are eligible for GoalSharing with a target opportunity generally equal to 5% of base salary. GoalSharing payouts may be 0% to 10% of base salary. GoalSharing payouts are determined as described on page 58. In 2025 the NEO's GoalSharing paid out at 7.25% of base salary for all NEOs except Mr. Nelson and Mr. Zhang whose GoalSharing payouts were 6.72% of base salary and 7.23% of base salary, respectively.

See page 68 for details on the 2025 PIP and GoalSharing metrics and actual results for the year.

**Long-Term Incentives**

We believe it is important to link LTI metrics to financial measures that will drive the success of our strategic priorities and generate long-term value for our shareholders. We also believe it is important for a significant percentage of LTI to be in the form of equity to align our executives' financial interests with those of our shareholders.

Our LTI construct for 2025 is as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  |  | **Vehicle** | **Vehicle** |  |  |
|  | **% of LTI Target** | **Cash** | **Equity** | **Performance-Based** | **Time-Based** |
| &nbsp;&nbsp;Cash Performance Units (CPUs) | 25% | ✓ |  | ✓ |  |
| &nbsp;&nbsp;Performance Share Units (PSUs) | 45% |  | ✓ | ✓ |  |
| &nbsp;&nbsp;Restricted Stock Units (RSUs) | 30% |  | ✓ |  | ✓ |

---

LTI targets are established by the Compensation Committee for each NEO annually in February.

66 CORNING 2026 PROXY STATEMENT

[**Table of Contents**](#toc)

Compensation Discussion & Analysis

In 2025, LTI targets for our NEOs were increased as a noted below:

---

| | | |
|:---|:---|:---|
| **NEO** | **2024 LTI Target Value** | **2025 LTI Target Value** |
| Wendell P. Weeks | $12650000 | $13650000 |
| Edward A Schlesinger | $2500000 | $3850000 |
| Eric S. Musser | $4750000 | $5000000 |
| A. Hal Nelson III | $2450000 | $3700000 |
| Lewis A. Steverson | $3800000 | $4125000 |
| John Z. Zhang | $2450000 | $3700000 |

---

Similar to the other elements of compensation noted above, the LTI targets for these key executives were increased in recognition of the contributions of these key executives to our strong 2024 results and the sustained momentum enabled by the successful execution of the Springboard plan as well as to align their compensation with their increased responsibilities and external market benchmarks as described above. For Mr. Weeks, Mr. Musser and Mr. Steverson, the Committee also took into consideration that the LTI targets for these executives had not been increased since 2022.

**2025 Performance and Compensation Alignment**

In 2025, our results exceeded those set forth in our Springboard plan. As a result of our excellent performance, we delivered double-digit sales growth with core net sales at $16.41 billion for the year, and achieved on both of our key Springboard targets of adding $4 billion of incremental annualized sales and achieving a 20% operating margin a full year early. Additionally, our core EPS of $2.52 reflected growth at twice the rate of sales and an increase of 28.6% year over year, and our adjusted free cash flow at $1.72 billion grew three times faster than sales and reflected year over year growth of $460 million. As a result of these significantly favorable results, each of our metrics reflected a payout significantly above their respective targets including our ROIC modifier in our long term incentive plan, which was +10% based on a three-year 290 basis point improvement. The strength of these results has underscored confidence in our Springboard plan and is reflected in our favorable TSR performance (1-year TSR of approximately 88%).

See page 9 for more performance highlights and page 62 for further TSR details.

Details of our financial targets for 2025 compared to 2024 actual results are shown on the chart on page 63.

Further details regarding how our performance targets are set can be found beginning on page 56.

**PIP: The final PIP payout for our NEOs is 140% of target, except Mr. Nelson and Mr. Zhang whose final PIP payouts are 133% and 144%, respectively.** PIP performance measures and payout factors for our NEOs are described on page 57.

**GoalSharing: The final GoalSharing payout for NEOs is 7.25% of their base salaries for all NEOs except Mr. Nelson and Mr. Zhang whose GoalSharing payouts were 6.72% of base salary and 7.23% of base salary, respectively.** GoalSharing payout is determined as described on page 58.

**LTI: 2025 CPU and PSU Performance Measures**

**PSUs and CPUs** represent 45% and 25% of the annual target LTI value, respectively. Payout is based on cash generation and sales growth—measures that support our long-term financial health and success. The 2025 performance measures for PSUs and CPUs are:

1) Adjusted free cash flow (70%) which focuses on generating cash to ensure the Company's financial stability and to allow for investment in innovation and future growth as well as shareholder distributions, and

2) Core net sales (30%) which focuses on growth.

68 CORNING 2026 PROXY STATEMENT

[**Table of Contents**](#toc)

Compensation Discussion & Analysis

**Actual CPUs and PSUs earned are based on the average of the actual performance for each year in the three-year period and are subject to an ROIC modifier of up to ±10% (for the years 2025, 2026 and 2027).** CPUs and PSUs granted in 2025 will be paid out (in the case of CPUs) or vested and released (in the case of PSUs) in 2028 based on:

&nbsp;&nbsp;&nbsp;&nbsp;• Performance against financial
 targets, which are set at the beginning of each year of the three-year performance period, and

• ROIC improvement over
 the entire performance period, as measured by the ROIC modifier. The improvement target for the ROIC modifier is established at the
 beginning of the three-year performance period, and the modifier acts as a multiplier of -10% to +10% to the three-year average performance
 results.

See the description below for details on the 2025 CPU and PSU metrics and actual results for the year as well as the results for the three-year plan ending in 2025, covering the performance period from 2023-2025.

**RSUs represent 30% of the annual target LTI value.** The number of RSUs granted is determined based on the closing stock price on the grant date (the first business day in April), and awards cliff vest approximately three years from the grant date.

**2025 CPU & PSU Performance Measures**

![](glw4500541-def14a1x71x1.jpg)

\*Adjusted free cash flow goals are set independently each year and not with reference to prior years' goals or results as the Company's cash needs, including capital, will vary year to year based on various strategic factors.

**2023-2025 CPU and PSU ROIC Modifier (Multiplier) 3-year ROIC Improvement**

**Starting Point - December 31, 2022 - ROIC: 9.5%**

![](glw4500541-def14a1x71x2.jpg)

We define ROIC for compensation purposes 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, Mexican peso, and the euro against the U.S. dollar, and a constant tax rate of 21%. Invested capital is the sum of total equity plus debt less derivative assets and liabilities. ROIC improved by 290 basis points over the 3-year period, which exceeded our target resulting in an ROIC modifier of +10% on the +/-10% scale.

Please see page 8 for more information about our Core Performance Measures and Appendix A for a reconciliation of the non- GAAP measures to the most directly comparable GAAP financial measures.

Compensation Discussion & Analysis

**CPUs and PSUs — Our Three-Year Performance — How It Works**

The following illustration shows how earned CPUs and PSUs are calculated at the end of the three-year performance period. The 2025 performance result is the third performance year of the three-years ending in 2025 (2023, 2024 and 2025), which is averaged and then subject to the ROIC modifier, which is a multiplier (of up to +/- 10%) on the average result.

![](glw4500541-def14a1x72x1.jpg)

\*Performance targets are generally established in February each year for the calendar year. See page 68 for performance measures and results for the applicable year.

\*\*3-year ROIC improvement target is established at the beginning of each three-year performance period. See page 70 for the 2023-2025 performance measures and results.

Restricted Stock Units: In addition to the performance metric-driven compensation described above, 30% of each executive's target Long-Term Incentive award is delivered in the form of time-based RSUs that will vest after three years. These RSUs are not tied to specific performance measures; however their value is impacted by changes in the Company's stock price. The impact of our stock price, along with the three-year vesting period, help to further align the compensation of our executives with the performance outcomes of our shareholders and provide an ongoing retention benefit for executives, in particular with respect to those executives who are not yet retirement-eligible.

**CEO Compensation**

Over the past two decades under Mr. Weeks' leadership, Corning has significantly expanded its global reach, reinforced its American manufacturing capabilities, solidified its position as a market leader in key businesses, and continued to create and scale breakthrough technology platforms. The Company has delivered durable growth while maintaining a strong focus on operational excellence and disciplined capital management. Recent innovations include the ongoing expansion of Corning<sup>®</sup> Gorilla<sup>®</sup> Glass into new device categories, the advancement of Optical Communications solutions to support next-generation connectivity and data centers and the domestic deployment of advanced glass technologies for the semiconductor and solar industries, enabling critical components for chip manufacturing and renewable energy solutions. Corning's relentless pursuit of innovation has enabled it to remain the lowest-cost producer in core businesses and to address evolving customer needs across the display, optical communications, environmental technologies, mobile consumer electronics, and life sciences markets.

Mr. Weeks' extensive leadership experience and long-standing tenure as CEO have been invaluable to the Company and its Board, successfully steering Corning through the global pandemic, supply chain disruptions, economic volatility, and inflationary pressures—while continuing to drive substantial growth across our businesses. Under Mr. Weeks' guidance, Corning:

&nbsp;&nbsp;&nbsp;&nbsp;• Not only advanced but
 exceeded the strategic objectives of its Springboard plan, announced in late 2023, with 2025 results surpassing targets for revenue
 and profitability and creating strong TSR performance to benefit shareholders;

• Emerged as a global leader
 in the development of advanced optical and materials solutions that are foundational to the rapid expansion of AI infrastructure
 worldwide, supporting the next generation of data centers and connectivity; and

• Achieved record performance
 in its Optical Communications and Specialty Materials businesses, expanded into semiconductor and solar glass innovations, and increased
 investments in manufacturing capacity and automation.

In recognition of our strong 2024 results and the sustained momentum enabled by the successful execution of the Springboard plan, including Corning's strategic impact on AI enablement, the Compensation and Talent Management Committee approved adjustments to Mr. Weeks' compensation to acknowledge his exceptional leadership and performance. For Mr. Weeks' LTI target,

[**Table of Contents**](#toc)

Compensation Discussion & Analysis

the Committee also considered that Mr. Weeks had not received an increase since 2022. Mr. Weeks' pay components were increased as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• **Base salary** –
 Increased by 4% in line with average increases for all U.S. salaried employees.

• **Short-Term Incentives** –
 2025 PIP target was increased by 10% to 160% (from 150%) while GoalSharing targets were unchanged at 5% of base salary.

• **Long-Term Incentives** –
 Target grant value increased by $1 million to $13.65 million.

Mr. Weeks' compensation is strongly aligned with Company performance, with 91% of Mr. Weeks' target pay delivered through incentives that are directly tied to Corning's business, operating and financial performance or stock price (via equity).

**Robust Compensation Program Governance**

Corning has rigorous and robust governance with respect to its executive compensation plan:

**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, and 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 Corning's long-term success. Our non-qualified ESPP covers about 19 active participants, including all NEOs. The percentage of cash compensation earned as a retirement benefit under the ESPP is a maximum of 50% of final average pay for 25 or more years of service. The definition of pay used to determine benefits includes base salary and annual cash

CORNING 2026 PROXY STATEMENT 71

[**Table of Contents**](#toc)

Compensation Discussion & Analysis

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. As of December 31, 2025, all 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" beginning on page 84.

**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 reported under perquisites in the Summary Compensation Table.

**Other Executive Perquisites:** We provide the NEOs with an 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 the imputed income resulting from these perquisites.

Given the limited commercial flight options available in the Corning, New York area, the Compensation 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 Compensation Committee establishes annual personal aircraft usage caps under this program (both in absolute dollar value and hours) for each NEO. The established cap for the CEO and Chief Operating Officer (COO) was $170,000 in the case of Mr. Weeks, $162,500 in the case of Mr. Musser, and 100 hours for each. The cap for the other NEOs was approximately three-quarters of the CEO cap or lower. Actual personal utilization in 2025 fell well below these caps. For additional details, refer to footnotes relating to "All Other Compensation" included with the Summary Compensation Table beginning on page 77.

**Relocation and Expatriate-Related Expenses:** 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 in connection 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 2025, Mr. Zhang was eligible for expatriate benefits due to his temporary international assignment to Shanghai, China. These amounts are included in footnote 5, section (iii) to the Summary Compensation Table beginning on page 77.

**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 – Severance Agreements" beginning on page 87.

**Executive Change-in-Control Agreements:** The Compensation 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 Compensation 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 to receive severance benefits. Additional details about the specific agreements can be found under "Arrangements with Named Executive Officers – Change-in-Control Agreements" beginning on page 89.

&nbsp;&nbsp;**In 2012, the Compensation Committee approved updated forms of agreements for all corporate officers entering into severance and change-in-control agreements after July 2004. These agreements 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. All NEOs except Mr. Weeks have the new form of agreements, whereas Mr. Weeks has a grandfathered agreement that was entered into prior to July 2004.**

Compensation Discussion & Analysis

Compensation Peer Group

Corning is a diversified technology company with five reportable business segments. Most 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 and, while such businesses may be a competitor to one of our businesses, are not appropriate peers to our Company as a whole. 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). These companies, and not competitors to our individual businesses, are those included in our Compensation Peer Group.

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

• **As a result, Corning looks to globally diversified companies or innovation companies in other industries to find companies of similar size and complexity.** 

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 TrueView Survey and the Radford Total Compensation Database for Executives. These 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.

**2025 Compensation Peer Group**

Our 2025 Compensation Peer Group is set forth below.

In 2022 the Compensation Committee (with the assistance and advice of its consultant, Frederic W. Cook & Co., Inc.) reviewed and approved changes to the Compensation Peer Group removing two companies (Thermo Fischer Scientific and Broadcom) and adding seven new companies (Honeywell International, 3M Company, Illinois Tool Works, Emerson Electric, Amphenol Corporation, IQVIA Holdings and DuPont de Nemours). This had the net effect of increasing the Compensation Peer Group from 21 companies to 26 companies with the goal of creating a data set of sufficient size which would not require further update for several years, outside of adjustments for peer M&A activity, etc. In 2025, Juniper Networks, Inc. was replaced by Hewlett Packard Enterprise (HPE) in our Compensation Peer Group as a result of HPE's acquisition of Juniper Networks, Inc. in mid-2025. Performance data for both Juniper Networks, Inc. and HPE are excluded given that each company was a peer for part of the year.

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., base salary, STI and LTI 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 $19.2 million, and 75th percentile target total direct CEO compensation was $24.1 million, compared with Corning target total direct CEO compensation of $18.2 million. The Compensation Committee deems this market position for CEO pay to be appropriate given (a) Mr. Weeks' strong performance in managing the complexity of the Company and (b) his years of experience in the role. 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 sole authority to retain and terminate its compensation consultant and approve the consultant's fees and all other terms of engagement. Since 2014, the Compensation Committee has retained executive compensation experts from Frederic W. Cook & Co., Inc. (FW Cook).

In 2025, FW Cook attended all Compensation Committee meetings. FW Cook advises the Compensation Committee on all matters related to NEO and director compensation and assists the Compensation Committee in interpreting its data and recommendations received from the Company.

In 2025, the Company engaged Compensation Advisory Partners LLC (CAP) and Willis Towers Watson (WTW) to assist management and the Compensation Committee with various executive compensation matters and disclosures.

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

**Role of Executive Management in the Executive Compensation Process**

Corning's Chief Human Resources Officer 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 Compensation 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 executive officers (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 Compensation Committee. Recommendations for the CEO's compensation are prepared by the Compensation Committee's independent compensation consultant (FW Cook) and are not discussed or reviewed with the CEO prior to the Compensation Committee's review and the CEO is not present for discussion of his compensation by the Compensation Committee. The Compensation Committee recommends the CEO's compensation to the Board annually for approval.

After the annual budget is finalized each year, the Compensation Committee receives management's recommendations for the annual bonus and long-term incentive plans performance metrics and sets the final targets for the year.

The CFO and the Corporate Controller attend the annual Compensation Committee meeting to review the CD&A and at least one of them attends the portion of the February Compensation Committee meeting where performance metrics are reviewed.

**Clawback Policy**

The Compensation Committee of the Board has adopted a formal Compensation Clawback Policy, as required by the NYSE Listing Standards. The Clawback Policy provides for the recovery of incentive-based compensation erroneously received by current or former executive officers during the three fiscal years immediately preceding the year in which the Company is required to prepare an accounting restatement due to material noncompliance with financial reporting requirements. The requirements under the Clawback Policy are separate from any recoupment required by the Sarbanes-Oxley Act of 2002. The Compensation Committee also has discretion to seek recovery of any amount that it determines was received otherwise inappropriately by such individuals.

**Anti-Hedging Policy**

Our written insider trading policy, which governs trading activity by directors, officers and employees, and certain of their family members, prohibits selling or buying publicly traded options on Corning stock, or trading in any Corning stock derivatives. Additionally, the policy prohibits engaging in transactions in which the covered party may profit from short-term speculative swings in the value of Corning stock utilizing "short sales" or "put" or "call" options. For more information, see our written Insider Trading Policy, which is filed as an exhibit to our Annual Report on Form 10-K.

**Anti-Pledging Policy**

Our written insider trading policy, which governs trading activity by directors, officers and employees, and certain of their family members, prohibits holding Corning stock in a margin account or pledging Company securities as collateral for a loan. For more information, see our written Insider Trading Policy, which is filed as an exhibit to our Annual Report on Form 10-K.

**Accounting Implications**

In designing our compensation and benefits 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 and Talent Management Committee Report

The Compensation and Talent Management Committee ("Compensation 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 Compensation 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 Compensation Committee is responsible for interpreting Corning's executive compensation plans and programs. In the event of any questions or disputes, the Compensation 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 Compensation Committee. Additional details regarding the role and responsibilities of the Compensation Committee are defined in the Compensation Committee Charter, located in the Corporate Governance section of the Company's website.

The Compensation 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, as appropriate, for the year ended December 31, 2025.

(1) Includes all amounts
 paid in cash, or deferred under the Investment Plan and/or Supplemental Investment Plan.
 In 2023, it also includes the aggregate grant date fair value of RSUs granted under the Cash
 for Equity Exchange program in lieu of up to 40% of salary earned during the first half of
 2023.

(2) The amounts in
 the Stock Awards column reflect the aggregate grant date fair value computed in accordance
 with FASB ASC Topic 718 of awards of RSUs and PSUs granted pursuant to the long-term incentive
 plan. In 2023, this includes both the 20% premium applicable to amounts of salary paid in
 RSUs and the target value of PSUs granted in lieu of cash PIP under the 2023 Cash for Equity
 Exchange Program. Assumptions used in the calculation of these amounts are included in Note
 14 to the Company's audited financial statements for the fiscal year ended December
 31, 2025 included in the Company's Annual Report on Form 10-K filed with the SEC on
 February 12, 2026. This same method was used for the fiscal years ended December 31, 2024
 and 2023. There can be no assurance that the grant date fair value amounts will ever be realized.

(3) The amounts in
 the Non-Equity Incentive Plan Compensation column reflect the sum of annual short-term incentive
 payments earned under the 2025 GoalSharing and PIP plans, and the portion of earned CPU awards
 based on 2025 performance goals. GoalSharing awards were 7.25% of each NEO's year-end
 base salary, except for Nelson and Zhang whose GoalSharing payouts were 6.72% and 7.23% of
 their year-end base salaries, respectively (compared to a target payout of 5% of salary),
 and paid in February 2026. Cash PIP awards were 140% of each NEO's target percent multiplied
 by his year-end base salary, respectively, except for Nelson and Zhang whose PIP payouts
 were 133% and 144% of target percent multiplied by their year end base salaries, respectively.
 Musser's PIP and GoalSharing payouts were prorated to reflect his retirement on September
 30, 2025.

In addition to the 2025 GoalSharing and PIP awards noted above, the amounts in column (f) also reflect the earned portions of CPU Awards granted in 2025, 2024 and 2023 on the basis of 2025 performance against established measures. 2025 CPU award payouts will be made in February 2028 based on actual corporate performance compared to the established performance goals averaged over three years (2025, 2026 and 2027) and subject to a ±10% 3-year ROIC modifier as described starting on page 69. 2024 and 2023 CPU award payouts are based on performance goals averaged over three years (2024, 2025 and 2026 for 2024 CPUs; and 2023, 2024, and 2025 for 2025 CPUs), respectively, and are also subject to a ±10% 3-year ROIC modifier. Performance goals for 2026 and 2027 are yet to be established. While the final payout amounts for 2025 and 2024 CPU awards are unknown, the table below reflects the earned amount of 2025, 2024 and 2023 CPU awards, which are reflected in column (f) on the basis of 2025 performance metrics, and which exclude the portion of the 2025 award that remains unearned as a result of the 3-year performance modifier that is not yet known. The 3-year ROIC modifier for the period 2023-2025 is +10%, so the adjustment in the Summary Compensation Table as a result of this modifier is noted below since the amount "at risk" was previously unreported until final performance was known. Musser's 2025 CPU target is prorated to reflect his retirement on September 30, 2025.

following table shows "All Other Compensation" amounts provided to the NEOs in 2025. 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.

&nbsp;&nbsp;&nbsp;&nbsp;(i) Amounts shown above reflect personal aircraft usage
during 2025 (although the Executive Allowance runs from November 1 through October 31). Weeks' use of Corning aircraft for
travel to external board meetings is also included.

&nbsp;&nbsp;&nbsp;&nbsp;(ii) NEOs may use their executive allowance for residential security
or financial counseling services.

&nbsp;&nbsp;&nbsp;&nbsp;(iii) 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.
Zhang's expatriate assignment benefits pursuant to our standard global mobility program in connection with his assignment in Shanghai,
China are also included. Amounts listed for Zhang for 2025 include standard expatriate benefits related to housing ($323,259), cost
of living related allowances ($229,443), home leave and home country support ($114,698) as well as local country tax payments, tax preparation
and tax equalization ($911,172). Tax equalization expenses arise from additional taxes payable in respect of Zhang's compensation
as a result of his residence and work in China that are payable in addition to U.S. taxes. Our global mobility program is designed to
enable us to relocate talent where needed throughout our global business without creating financial hardships (or windfalls) for the
relocating individual(s). Expenses associated with a widely available corporate-leased apartment which was made available to Musser for
approximately three months related to his support of the transition of his responsibilities are also included. There was no incremental
cost to the Company for providing access to this otherwise unoccupied apartment.

&nbsp;&nbsp;&nbsp;&nbsp;(iv) This reflects Company-paid expenses relating to personal
and residential security benefitting Weeks and, through association, his family. Weeks' personal safety and security are of vital
importance to the Company's business and prospects, and the Board considers providing personal security in response to concerns
arising out of employment by the Company to be appropriate, business-related costs. However, because these costs can be viewed as conveying
a personal benefit to Weeks, they are reported as perquisites in this column.

(1) The
 amounts shown in columns (d), (e) and (f) reflect the award amounts under (i) the Company's
 2025 Performance Incentive Plan (PIP) (ii) the 2025 GoalSharing Plan and (iii) the Cash Performance
 Units (CPUs) under the Corning 2025 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%
 of the target award. 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 220% for CPUs, which represents the 200% performance metrics
 cap plus the maximum 10% ROIC modifier. PIP and GoalSharing awards are based on the individual's
 2025 bonus target and year-end base salary. Actual awards earned for CPUs are based on average
 performance against established metrics over three years (2025, 2026, 2027), 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 2028.

(2) The
 amounts shown in columns (g), (h) and (i) reflect the award amounts under the Performance
 Share Units under the Corning 2025 Corporate Performance Plan (2025 PSUs) and the portion
 of PSUs granted in 2023 and 2024 attributable to 2025 performance goals. Awards under this
 plan are paid in stock. If the threshold level of performance is not met, the payout will
 be 0% of the target award. If the performance target is met, the payout will be 100% of the
 target award. If the maximum level of performance is met for 2025 PSUs, the payout will be
 220% of the target award which represents the 200% performance metrics cap plus the maximum
 10% ROIC modifier. Actual awards earned for 2025 PSUs are based on average performance against
 established metrics over three years, adjusted up or down by up to 10% based on ROIC results
 versus the pre-established goal for the three-year period. 2023 PSUs will be payable in April
 2026, 2024 PSUs will be payable in April 2027, and 2025 PSUs will be payable in April 2028.
 The target number of 2025 PSU awards are 134,881; 38,043; 49,407; 36,561; 40,761; and 36,561
 to Weeks, Schlesinger, Musser, Nelson, Steverson, and Zhang, respectively. Because the grant
 date for a PSU occurs when the performance goals are approved, the reported number of shares
 reflects the portion of the 2025 PSUs for which performance goals have been set (i.e., 1/3
 of the total award).

(3) These
 amounts reflect the total grant date fair value computed in accordance with FASB ASC Topic
 718 of the portion of the 2023 PSUs pursuant to the Corning 2021 Long-Term Incentive Plan,
 which portion is attributable to 2025 performance measures established by the Committee (i.e.,
 1/3 of the total award). Amounts shown correspond to the amounts set forth in column (d)
 for 2025 of the Summary Compensation Table.

(4) These amounts reflect the total
 grant date fair value computed in accordance with FASB ASC Topic 718 of the portion of the 2024 PSUs pursuant to the Corning 2021
 Long-Term Incentive Plan, which portion is attributable to 2025 performance measures established by the Committee (i.e., 1/3 of the
 total award). Amounts shown correspond to the amounts set forth in column (d) for 2025 of the Summary Compensation
 Table.

(5) These
 amounts reflect the total grant date fair value computed in accordance with FASB ASC Topic
 718 of the portion of the 2025 PSUs pursuant to the Corning 2021 Long-Term Incentive Plan,
 which portion is attributable to 2025 performance measures established by the Committee (i.e.,
 1/3 of the total award). Amounts shown correspond to the amounts set forth in column (d)
 for 2025 of the Summary Compensation Table.

(6) These
 amounts reflect the total grant date fair value computed in accordance with FASB ASC Topic
 718 of restricted stock units granted in calendar year 2025 pursuant to the Corning 2021
 Long-Term Incentive Plan and correspond to the amounts set forth in column (d) for 2025 of
 the Summary Compensation Table. Awards vest 100% three years after grant date.

(7) Musser
 retired on September 30, 2025, and awards granted in 2025 (i.e., 2025 CPUs, PSUs and RSUs)
 were prorated for time worked in 2025 following retirement, with the remainder being forfeited.
 Prorated 2025 CPUs and PSUs remain subject to performance requirements pursuant to goals
 established by the Committee.

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, for those making voluntary contributions in 2022, 0.5% of plan compensation. 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. Beginning in January 2023 career average participants also receive a cash balance pay credit equal to 2.175% of pay.**

**Benefits earned under the cash balance formula are expressed as 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.**

**Mr. Weeks and Mr. Musser are earning benefits under the career average earnings formula. Mr. Schlesinger, Mr. Nelson, Mr. Steverson, and Mr. Zhang are earning benefits under the cash balance formula. All active and currently employed NEOs except Mr. Zhang are 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).**

**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 (the value of which is subtracted from the final ESPP annuity benefit). 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. Gross benefits for all NEOs are equal to 2.0% of average plan compensation multiplied by years of service up to 25 years (the "ESPP Formula"). 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 the ESPP Formula are available when a participant attains the earlier of age 60 with 10 years of service or age 55 with 25 years of service.**

**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.**

**All NEOs except Mr. Zhang 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 except for 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 age 55 with 25 years of service. No termination, disability or death was assumed to occur prior to retirement. Otherwise, the assumptions used are described in Note 11 to our consolidated financial statements for the year ended December 31, 2025, of our Annual Report on Form 10-K filed with the SEC on February 12, 2026.**

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 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 our current NEOs have more than three years of service with the Company, so all 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.

participation in the Supplemental Investment Plan by Weeks, Schlesinger, Nelson, and Zhang in the deferral of a portion of their 2025

year performance.

(2) Reflects Company match
 on the Supplemental Investment Plan, which was credited to the account of the Named Executive Officers in 2025. All of these amounts
 are included in the All Other Compensation column of the Summary Compensation Table (and are also detailed in footnote (5) to

(3) Reflects
 aggregate earnings on each type of deferred compensation listed above. 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
 16 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 and Nonqualified Deferred Compensation Earnings
 column of the Summary Compensation Table.

Arrangements with Named Executive Officers

Severance Agreements

**We have entered into severance agr**eements with each of our NEOs. All new executive severance agreements and executive change-in-control agreements executed 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. Mr. Weeks has an agreement in effect before July 2004. Mr. Schlesinger, Mr. Musser, Mr. Nelson, Mr. Steverson, and Mr. Zhang all have the new form of agreement.

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:

&nbsp;&nbsp;&nbsp;&nbsp;• 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 the sum of his then-base salary plus his annual target bonus amount (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 be entitled to accrued, but unpaid salary (lump sum payment) and any reimbursable expenses accrued or owing to him and, if terminated for cause, he would 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.**

CORNING 2026 PROXY STATEMENT 87

[**Table of Contents**](#toc)

Compensation Discussion & Analysis

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

&nbsp;&nbsp;&nbsp;&nbsp;• Accrued
 but unpaid base salary, reimbursable expenses, and the executive's target annual bonus, pro-rated to the last day of the month
 closest to the termination date (lump sum payment);

• For
 NEOs other than the COO whose base salary is less than $599,000, two (2) times the sum of (A) the base salary, and (B) the target
 bonus; for NEOs other than the COO whose base salary is equal to or greater than $599,000, three-and-a-half (3.5) times the base
 salary (only); and for the COO, four (4) times the base salary (only).

• A
 lump sum equal to the monthly COBRA premium times 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, 2025.

(1) Non-qualified
 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
 for all NEOs except for Musser and Zhang is an immediate life annuity. Musser's form
 of payment being received is a six-year certain and 100% joint and survivor. The amount shown
 above reflects the 100% joint and survivor annuity after the six year certain period ends.
 During the six year certain period, Musser's non-qualified annual annuity is $1,057,736
 and his qualified annuity is $134,150. Zhang's benefit would be a deferred life annuity.

(2) Non-qualified
 annuity payments in the event of death for Weeks, Schlesinger, Nelson, and Zhang are as follows:
 $2,095,179 for six years and $1,549,170 thereafter, $264,766 for six years and $226,130 thereafter,
 $496,171 for six years and $418,397 thereafter, and $93,512 for six years and $87,784 thereafter
 respectively. Death benefits on behalf of Steverson would be payable under the ESPP as a
 lump sum.

(3) The
 value of welfare benefits continuation is estimated at $21,554 per year for three years for
 Weeks. Benefits continuation for Schlesinger is $32,647, Nelson is $21,554, Steverson is
 $32,647, and Zhang is $10,028 per year respectively, for two years.

(4) 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 Weeks, a calculation of the
 executive's purchase price of the residence plus a percentage of documented improvements
 made to the property, if greater. 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).

(5) Musser
 is not eligible for severance benefits due to his retirement on September 30, 2025. The voluntary
 column shows amounts he will receive from the retirement plans.

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. Cash performance units and performance stock units are adjusted based on actual performance for completed performance periods and assumed performance of 100% for incomplete performance and adjusted CPUs and PSUs are vested and released immediately. Pension benefits earned in the ESPP also become immediately vested, and no longer subject to early retirement reductions, if any.

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

&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;• Accrued
 but unpaid base salary, reimbursable expenses, and the executive's target bonus, 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 the sum of his then-base salary plus annual target bonus amount (for Mr. Weeks). For NEOs other
 than the COO whose base salary is less than $599,000, two (2) times the sum of (A) the base salary, and (B) the target bonus;
 for NEOs other than the COO whose base salary is equal to or greater than $599,000, three- and-a-half (3.5) times the base salary
 (only); and for the COO, four (4) times the base salary (only). Severance is paid as a lump sum payment;

CORNING 2026 PROXY STATEMENT 89

[**Table of Contents**](#toc)

Compensation Discussion & Analysis

&nbsp;&nbsp;&nbsp;&nbsp;• Continued
 participation in the Company's health and welfare and risk benefit plans for 3 years for Mr. Weeks; and for other NEOs a lump
 sum equal to the monthly COBRA premium times 24;

• Upon request, purchase
 of the NEO's principal residence in the Corning, NY area at appraised value, or in the case of Mr. Weeks, a calculation of the
 executive's purchase price of the residence plus a percentage of documented improvements made to the property, if greater;
 and

• Outplacement
 benefits (equal to 20% of base salary, capped at $50,000) (excluding Mr. Weeks).

If the employment of an NEO (other than Mr. Weeks) is terminated for cause or he resigns other than for 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, and the executive's actual bonus, pro-rated to the last day of the month closest to the termination date (lump sum payment). In addition, Mr. Weeks 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 Internal Revenue Code. 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 other NEOs.

The following table reflects the amounts payable under the various arrangements assuming a change in control occurred on December 31, 2025.

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

(2) Musser
was not eligible for change in control benefits due to his retirement on September 30, 2025.

(3) Zhang
has cash severance capped under Section 280G best net provisions. Full cash severance (i.e., before a cutback) is $2,406,250. Under the
hypothetical calculations as of December 31, 2025, Zhang was above the Section 280G limit and better off on an after tax basis with his
cash severance cut back such that his total parachute payment would not exceed the Section 280G limit. The cash severance amount shown
reflects the reduced cash severance value that would result in his total payment being below the Section 280G limit.

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 Mr. Weeks, a calculation of the executive's purchase price of such residence and any documented improvements made to the property, if greater. This is data that Corning does not maintain in its normal course of business. See footnote (4) to the "Termination Scenarios" on page 88.

Pay Ratio Disclosure

**For 2025, the annual total compensation of the median employee, excluding our CEO, was $57,059 and the annual total compensation of our CEO was $25,756,121. Accordingly, the ratio of the CEO's annual total compensation to the annual total compensation of the median employee was 451:1.**

**This reflects analysis of our global workforce of employees as of October 1, 2025, which excludes 1 employee in Argentina, 53 employees in Brazil, 182 employees in Hungary, 474 employees in India, 3 employees in Pakistan, 11 employees in the Philippines, 7 employees in the Russian Federation, and 179 employees in Turkey (excluded employees are de minimis relative to the size of our global workforce). We used estimated total cash compensation to determine the median employee. Our estimate of total cash compensation for our full 2025 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 36 countries in which we operate, excluding Argentina, Brazil, Hungary, India, Pakistan, Philippines, Russian Federation 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, 2025 for the determination of the median and December 31, 2025 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

**Th**e Audit Committee evaluates our independent registered public accounting firm each year and has appointed PricewaterhouseCoopers LLP (PwC) as our independent registered public accounting firm for 2026. PwC has served in this role since 1944. The Audit 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 Audit Committee on non-audit services provided by PwC. The Audit Committee preapproves all audit and permitted non-audit services that PwC performs for the Company, and it approves the fees associated with the engagement of PwC. All services provided to Corning by PwC in 2024 and 2025 were pre-approved by the Audit Committee in accordance with the policy.

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

In determining whether to reappoint PwC, the Audit 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 Audit Committee and management, which include routine executive sessions
 with the Audit 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.

Based on its evaluation, the Audit 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, 2026. If the selection of PwC is not ratified by a majority of the votes cast by the holders of shares entitled to vote on the matter, the Audit Committee will

Audit Committee Matters

review its future selection of an independent registered public accounting firm in light of that vote result. Even if the selection is ratified, the Audit Committee in its discretion may appoint a different registered public accounting firm at any time during the year if the Audit 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.

Audit fees also include statutory audits, comfort letters, consents for other SEC filings and reviews of documents filed with the SEC.

*Audit-Related Fees*. These fees are composed of professional services rendered in connection with due diligence pertaining to acquisitions, procedures to translate certain financial statements for foreign subsidiaries, employee benefit plan audits, agreed-upon procedures, and other audit-related activities over systems pre-implementation review procedures.

*Tax Fees*. These fees are composed of statutory tax compliance, assistance for Corning's foreign jurisdiction subsidiaries' tax returns, tax transfer pricing services, and other tax consulting projects.

*All Other Fees.* Consists of fees not included in the Audit, Audit-Related, or Tax categories, including licensing technical accounting software and pre-assurance sustainability reporting readiness assessments from the independent registered public accounting firm.

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 chair 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 chair 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.**

Audit Committee Matters

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 Director**s. 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 2025, 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, 2025, 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, 2025 related to its audits of the consolidated financial statements and financial statement schedule, and the effectiveness of internal control over financial reporting.

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.

[**Table of Contents**](#toc)

![](glw4500541-def14a1x101x1.jpg)

At Corning, we are deeply committed to upholding strong corporate governance practices that align with our Values and support the long-term interests of our shareholders. We value constructive engagement with our shareholders and stakeholders, and we actively seek their perspectives on key issues affecting our Company. Over the past year, we have engaged directly with the proponent of the shareholder proposal below, as well as shareholders representing approximately 33% of our outstanding shares, to discuss their views and provide transparency regarding Corning's governance framework, policies and practices.

The following proposal was submitted for inclusion in this Proxy Statement by the AFL-CIO Reserve Fund which has represented to Corning that it has continuously been the beneficial owner of a sufficient amount of the Company's securities for a sufficient time period as required by Rule 14a-8. We will promptly provide you with the address and, to our knowledge, the number of voting securities held by the proponent of the shareholder proposal upon receiving a written or oral request directed to Corning's Corporate Secretary at One Riverfront Plaza, Corning, NY 14831. In accordance with rules of the SEC, other than minor formatting changes, we are reprinting the proposal and supporting statement as it was submitted to us. You may vote "FOR", "AGAINST" or "ABSTAIN", with respect to this Shareholder Proposal. If you "ABSTAIN" from voting, the abstention will not constitute a vote cast and will have no effect on the outcome.

Proposal 4: Request to Adopt an Independent-Chair Policy

RESOLVED: Shareholders of Corning Incorporated (the "Company") urge the Board of Directors (the "Board") to adopt a policy to require that the Chair of the Board (the "Chair") shall be an independent director who has not previously served as an executive officer of the Company.

This policy shall apply prospectively so as not to violate any contractual obligations, with amendments to the Company's governing documents as needed. The policy should also specify the process for selecting a new independent Chair if the current Chair ceases to be independent between annual meetings of shareholders. Compliance with the policy may be excused if no independent director is available and willing to be Chair.

**Shareholder's Supporting Statement**

We believe that an independent Chair will enhance the independent leadership of the Board. In our opinion, the Board's oversight of management can be diminished when the Board Chair is not an independent director. We favor having an independent Board Chair to provide a more robust oversight of risk including of environmental, social, and governance issues. Independent board chairs have become more common in recent years. In 2025, 42 percent of S&P 500 Index company boards were chaired by an independent director, compared to 29 percent a decade ago.<sup>1</sup>

According to Institutional Shareholder Services, "boards with independent leadership (either via an independent Chair or a Lead Director) are more likely to be more diverse, have more balance tenure, are more responsive to shareholders, while their CEO pay levels are less likely to be excessive relative to peers."<sup>2</sup> According to Glass Lewis, "shareholders are better served when the board is led by an independent chairman who we believe is better able to oversee the executives of the Company and set a pro-shareholder agenda without management conflicts that exist when the CEO or other executive also serves as a chairman."<sup>3</sup>

For these reasons, we urge shareholders to vote FOR this resolution.

Shareholder Proposal

**Corning's Statement in Opposition to Proposal 4**

---

| | |
|:---|:---|
| **AGAINST** | &nbsp;&nbsp;Our Board unanimously recommends you vote AGAINST Proposal 4 |

---

The Board views the flexibility to determine its own leadership structure as a fundamental governance responsibility and competitive advantage. This flexibility enables the Board to select the leadership configuration that best supports Corning's strategic priorities and provides the expertise needed to guide the Company through phases of growth and transformation. Imposing a rigid, one-size-fits-all policy would undermine the Board's ability to exercise informed judgment about what leadership structure best serves shareholders at any given time. Rather than addressing a real issue, such a mandate would introduce unnecessary rigidity that could ultimately disadvantage the Company and our shareholders.

Corning's current Board leadership structure, combining the roles of Chairman and CEO with a strong Lead Independent Director, has produced exceptional results, delivering strong shareholder returns over the last five years and significantly outperforming our peers and the S&P 500. This structure has enabled the Board to oversee major inflection points, such as expanding our advanced manufacturing capabilities to supply critical solar components to the U.S. energy supply chain, implementing strategic succession planning, and managing other complex initiatives that have demanded strong governance and oversight.

The Board believes this leadership structure is key to the effective execution of Corning's long-term strategy. With Mr. Weeks serving as both Chairman and CEO, there is clear alignment between the Board's strategic vision and management's operational execution as well as transparent communication between management and the Board. The Board believes this unified leadership is especially important, both internally and externally, as Corning navigates complex technological transformations. Forcing a separation of these roles could lead to inefficiencies and mixed signals at a time when clarity and cohesion provide a real competitive edge. Our results clearly demonstrate that Corning's current leadership structure delivers both operational excellence and sustained long-term value for shareholders, while ensuring strong, consistent governance.

In line with principles of sound governance and shareholder expectations, Corning's Corporate Governance Guidelines require the Board to review its leadership structure annually, including whether the role of Chairman and CEO should be separate. In making these determinations, the Board considers many factors, including the current circumstances of the Company, the composition of the Board, and the best interests of the Company's shareholders.

Our Corporate Governance Guidelines also state that when the roles of Chairman and CEO are combined, our independent directors must appoint a Lead Independent Director. This role carries significant, well-defined authority, including leading executive sessions at every Board meeting, providing feedback to our CEO on independent director deliberations, approving agendas and Board information, facilitating CEO performance reviews and ongoing management succession planning, engaging directly with shareholders, and serving as the key liaison between our independent directors and management. Our current Lead Independent Director, Dr. Stephanie A. Burns, provides robust independent oversight by actively leading executive sessions of our independent directors, directly engaging with major shareholders on governance matters, working directly with management to determine key areas of focus, leveraging her extensive leadership experience and technical expertise to challenge and oversee strategy and risk decisions, and managing the Board's oversight of the CEO. Dr. Burns' leadership is not ceremonial: she actively shapes Board priorities, ensures independent director voices are heard, and maintains direct dialogue with major shareholders. In addition, her deep leadership experience and industry expertise enables her to provide substantive challenge to the CEO and management on technical and strategic matters.

Corning also upholds robust, shareholder-friendly governance policies, including annual director elections, majority voting, proxy access, stringent stock ownership requirements for our directors and key officers, annual Board and committee self-evaluations, and active shareholder engagement. These practices foster transparency, accountability, and ongoing alignment with shareholder interests.

Corning sincerely values engagement with our shareholders and has carefully considered this proposal. The Board strongly believes that Corning's current governance practices and leadership structure represent a thoughtful, proven approach that has delivered exceptional results for shareholders. Adopting a policy mandating an independent chair would strip the Board of essential flexibility without providing corresponding benefits. It would impose a one-size-fits-all policy on a company that has thrived through adaptability and strategic alignment with its stakeholders, customers, and markets as circumstances demand. Most importantly, it would fix what is not broken, attempting to improve upon a governance structure that has already proven its effectiveness. We ask shareholders to preserve the Board's ability to exercise its business judgment in determining the optimal leadership structure for Corning's continued success.

For these reasons, the Board of Directors unanimously recommends a vote **AGAINST** this proposal.

For more information about our governance practices and the role and qualifications of our Lead Independent Director, please refer to pages 33 and 34.

You may vote if you owned shares of our common stock as of the close of business on March 2, 2026, the record date for the Annual Meeting.

How Many Votes Do I Have?

You are entitled to one vote for each share of common stock you own. As of the close of business on March 2, 2026, we had 859,014,837 shares of common stock 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 ProxyVote.com;

• By
 telephone (from the United States and Canada only) at **1-(800)-690-6903**; or

• 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 <u>one</u> of 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?"

How Do I Vote My Shares During the Annual Meeting?

Even if you plan to attend and participate in our virtual Annual Meeting, we encourage you to vote by telephone or over the Internet, or by returning a proxy card following your request for printed materials. This will ensure that your vote will be counted if you are unable to, or later decide not to, participate in the virtual Annual Meeting. Whether you are a shareholder of record or hold your shares in "street name," you may vote online at the Annual Meeting.

Frequently Asked Questions About the Meeting and Voting

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:

• voting again by Internet or telephone prior to the meeting;

• voting again at the meeting; or

• 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.

You also may revoke your proxy prior to the meeting without submitting any new vote by sending a written notice that you are withdrawing your vote to our Corporate Secretary at the address listed above.

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 your proxy card or the notice you previously received. 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 your proxy card or the notice you previously received. 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 cases where a broker votes on certain proposals but does not vote on other proposals, this results in a "broker non-vote." Broker non-voted shares count toward achieving a quorum requirement for the Annual Meeting.

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. For Proposals 1, 2 and 4, broker non-votes will not count as votes cast and will not affect the determination of whether those proposals are approved or rejected. Therefore, it is important that you provide voting instructions to your broker.

Frequently Asked Questions About the Meeting and Voting

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

 the fiscal year ending December 31, 2026 (Proposal 3); and

If you are the registered holder, you may contact our transfer agent, Computershare Trust Company, N.A., at 1-(800)-255-0461.

May Shareholders Ask Questions at the Virtual Annual Meeting?

Yes. We have designed the format of the virtual Annual Meeting to ensure that our shareholders are afforded the same rights and opportunities to participate as they would have at an in-person meeting. After the business portion of the Annual Meeting concludes and the meeting is adjourned, we will hold a Q&A session during which we will answer questions submitted during the meeting that are pertinent to the Company, as time permits, and in accordance with our Rules for Conduct of the Shareholder Meeting. During the Annual Meeting, you can view our Rules for Conduct of the Shareholder Meeting and submit any questions at virtualshareholdermeeting.com/GLW2026. Answers to any questions not addressed during the meeting will be posted on the investor page of our website following the meeting. Questions and answers will be grouped by topic, and substantially similar questions will be answered only once.

How Many Shares Must be Present to Hold the Meeting?

In order for us to conduct our meeting, a majority of our outstanding shares of common stock as of March 2, 2026, the record date for the meeting, must be present in person (by logging in to our virtual annual meeting with your control number) or by proxy at the meeting.

We also will reimburse brokers for their costs in sending proxies and proxy materials to our shareholders so that you may vote your shares. Our directors, officers and regular employees may supplement Innisfree's proxy solicitation efforts by contacting you by telephone or electronic communication or in person. We will not pay directors, officers or other regular employees any additional compensation for their proxy solicitation efforts.

How Can I Find the Voting Results of the Annual Meeting?

After the Annual Meeting, we will include the voting results in a Form 8-K, which we will file with the SEC on or before May 6, 2026.

Shareholder Proposals and Director Nominations for the 2027 Annual Meeting

Under Rule 14a-8 of the Securities Exchange Act of 1934 (the Exchange Act), eligible shareholders may submit proposals for inclusion in the proxy statement for our 2027 Annual Meeting. Shareholder proposals must comply with the requirements established by the SEC and must be submitted in writing and received by our Corporate Secretary on or before the close of business on November 20, 2026 (for them to be considered for inclusion in the 2027 proxy statement).

Our by-laws permit a group of shareholders (up to 20) who have owned at least 3% of Corning's common stock for at least 3 years to submit director nominees for the greater of two directors or the largest whole number that does not exceed 20% of

our Board. These director nominees will be included in our proxy statement for the 2027 Annual Meeting if the shareholder(s) and the nominee(s) satisfy the requirements specified in our by-laws. Notices of director nominees submitted under these by-law provisions must be received no earlier than December 31, 2026 and no later than January 30, 2027.

If you would like to present a matter not included in our proxy statement for consideration at our 2027 Annual Meeting, including nominations for director candidates, you must send advance written notice to our Corporate Secretary no earlier than the 120th day prior to the first anniversary of the preceding year's annual meeting (December 31, 2026) and no later than the close of business on the 90th day prior to the first anniversary of the preceding year's annual meeting (January 30, 2027). Any matter or nomination must comply with our by-laws. Eligible shareholders who intend to solicit proxies for the 2027 Annual Meeting in support of director nominees other than the Company's nominees under Rule 14a-19 of the Exchange Act must comply with the requirements of the Company's by-laws and provide the notice required by, and in compliance with, Rule 14a-19 no later than March 1, 2027.

All proposals in this section should be addressed to **Corporate Secretary, Corning Incorporated, One Riverfront Plaza, Corning, New York 14831** and must be received by the applicable dates specified above.

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/2026-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 2025 Annual Report on Form 10-K 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 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 (866) 540-7095 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 request delivery of a single copy of a proxy statement or Annual Report on Form 10-K if you are receiving multiple copies.

Code of Ethics

Our Board of Directors adopted (i) the Code of Conduct for Directors and Executive Officers, which supplement our Code of Conduct that governs all employees and directors and (ii) the Code of Ethics for the Chief Executive Officer and Financial

Executives (Code of Ethics). These Codes have existed for over ten years. The Code of Ethics applies to our Chief Executive Officer, Chief Financial Officer, Controller and other financial executives. During 2025, no amendments to or waivers of the Code of Ethics provisions were made for any of our directors or executive officers.

**CORNING INCORPORATED AND SUBSIDIARY COMPANIES**

**CORE PERFORMANCE MEASURES** 

In managing the Company and assessing our financial performance, we adjust certain measures included in our consolidated financial statements to exclude specific items to arrive at measures that are not calculated in accordance with accounting principles generally accepted in the United States of America ("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.

Management uses core performance measures, along with GAAP financial measures, to make financial and operational decisions and certain of these measures also form the basis of our compensation program metrics. Management believes that our core performance measures are indicative of our core operating performance and provide investors with greater visibility into how management evaluates our results and trends and makes business decisions. These measures are not, and should not be viewed as a substitute for, GAAP reporting measures.

Items that are excluded from certain core performance calculations include: the impact of translating foreign denominated debt, the impact of the translated earnings contracts, acquisition-related costs, certain discrete tax items and other tax-related adjustments, restructuring, impairment and other charges and credits, certain litigation, regulatory and other legal matters, pension mark-to-market adjustments and other items which do not reflect the ongoing operating results of the Company.

In addition, because a significant portion of our revenues and expenses are denominated in currencies other than the U.S. dollar, management believes it is important to understand the impact on sales and net income of translating these currencies into U.S. dollars. Therefore, management utilizes constant-currency reporting for the Optical Communications, Display, Specialty Materials, Automotive and Life Sciences segments to exclude the impact from the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro, as applicable to the segment. The most significant constant-currency adjustment relates to the Japanese yen exposure within the Display segment. The constant-currency rates established for our core performance measures are long-term management-determined rates, which are closely aligned with our hedging instrument rates. These hedging instruments may include, but are not limited to, foreign exchange forward or option contracts and foreign-denominated debt. For details of the rates used, refer to the footnotes included in the "Items Adjusted from GAAP Measures" section.

We believe that the use of constant-currency reporting allows management to understand our results without the volatility of currency fluctuations, analyze underlying trends in the businesses and establish operational goals and forecasts.

For a reconciliation of non-GAAP performance measures to their most directly comparable GAAP financial measure, see the tables and footnotes included below. With respect to the outlook for future periods, it is not possible to provide reconciliations for these non-GAAP measures because management 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 management's control. As a result, management is unable to provide outlook information on a GAAP basis.

**Items Adjusted from GAAP Measures**

(1) <u>Constant-currency adjustment</u>: As a significant portion of revenues and expenses are denominated in currencies
 other than the U.S. dollar, management believes it is important to understand the impact
 on sales and net income of translating these currencies into U.S. dollars. The Company utilizes
 constant-currency reporting for Optical Communications, Display, Specialty Materials, Automotive
 and Life Sciences segments for the Japanese yen, South Korean won, Chinese yuan, New Taiwan
 dollar, Mexican peso and euro, as applicable to the segment. We believe that the use of constant-currency
 reporting allows management to understand our results without the volatility of currency
 fluctuation, analyze underlying trends in the businesses and establish operational goals
 and forecasts. For the years ended December 31, 2025 and 2024, the constant-currency adjustment
 primarily relates to our Japanese yen exposure due to the difference in the average spot
 rate compared to our core rate. The constant-currency rates established for our core performance
 measures are long-term management-determined rates, which are closely aligned with our hedging instrument rates. These hedging instruments
 may include, but are not limited to, foreign exchange forward or option contracts and foreign-denominated debt. Effective January
 1, 2025, management updated the constant-currency rates and the updated rates were applied prospectively beginning with reporting
 periods in 2025. Comparative results were not recast and are reported based on the 2024 rates. Constant-currency rates used are as follows and are applied to
 all periods presented and to all foreign exchange exposures during the period, even though we may be less than 100% hedged:

(2) <u>Translation of foreign denominated debt, net</u>: Amount reflects the gain or loss on the translation of our yen-denominated and euro-denominated
 debt to U.S. dollars, net of gains or losses on related hedging instruments.

(3) <u>Translated earnings contract, net</u>: Amount reflects the impact of the realized and unrealized gains and losses from the Japanese yen, South
 Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro-denominated foreign currency hedges related to translated earnings.

(4) <u>Acquisition-related costs</u>: Amount reflects intangible amortization, inventory valuation adjustments, contingent consideration adjustments and external
 acquisition-related deal costs, as well as other transaction related costs.

(5) <u>Discrete tax items and other tax-related adjustments</u>: Amount reflects certain discrete period tax items such as changes in tax law, the
 impact of tax audits, changes in tax reserves, changes in deferred tax asset valuation allowances and stock compensation windfall
 or shortfall, as well as other tax-related adjustments.

112 CORNING 2026 PROXY STATEMENT

[**Table of Contents**](#toc)

Appendix A

&nbsp;&nbsp;&nbsp;&nbsp;(6) <u>Restructuring, impairment and other charges and credits</u>: Amount reflects certain restructuring, impairment losses and other charges and credits, as well
 as other expenses, including severance, accelerated depreciation, asset write-offs and facility repairs resulting from power outages,
 and the recognition of cumulative foreign currency translation adjustments upon the substantial liquidation or disposition of a foreign
 entity, which are not related to ongoing operations. For the year ended December 31, 2024, amount includes $131 million of non-cash
 cumulative foreign currency translation losses required to be recognized upon the substantial liquidation or disposition of foreign
 entities, which was recorded in other (expense) income, net on the consolidated statements of income. Amount also includes $49 million
 of non-cash charges in one of our Emerging Growth Businesses relating to a customer that recently entered into a multi-jurisdictional
 restructuring effort including insolvency filings in certain countries. These charges primarily relate to the full write-down of
 upfront payments made to the customer, which were determined to be nonrecoverable, and recorded as a charge to net sales on the consolidated
 statements of income. Other charges recorded during 2024 related to asset write-offs associated with the exit of certain facilities
 and product lines. The activity in 2023 primarily relates to asset write-offs associated with the exit of certain facilities and
 product lines and severance charges across all segments.

(7) <u>Litigation, regulatory and other legal matters</u>: Amount reflects developments in commercial litigation, intellectual property disputes, adjustments to
 our estimated liability for environmental-related items and other legal matters.

(8) <u>Pension mark-to-market adjustment</u>: Amount primarily reflects 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.

(9) <u>Loss (gain) on investments</u>:
 Amount reflects the loss or gain recognized on investments due to mark-to-market adjustments for the change in fair value or the
 disposition of an investment.

(10) <u>Loss (gain) on sale of assets</u>: Amount represents the loss or gain recognized for the sale of assets, recorded in cost of sales, on the consolidated
 statements of income.

(11) <u>Loss on sale of business</u>:
 Amount reflects the loss recognized for the sale of a business, recorded in other (expense) income, net on the consolidated statements
 of income, and includes $14 million for the year ended December 31, 2024 of non-cash cumulative foreign currency translation losses
 related to the disposition of a foreign entity.

(12) <u>Equity in losses of affiliated companies</u>: Amount reflects costs not related to continuing operations of affiliated companies, such as restructuring, impairment
 losses, inventory adjustments, other charges and credits.
