PROXY STATEMENT

Annual Meeting of Stockholders

To be Held on May 26, 2026

To Stockholders of Silgan Holdings Inc.:

This Proxy Statement and the accompanying proxy card are furnished in connection with the solicitation of proxies by the Board of Directors of Silgan Holdings Inc., or Silgan Holdings or the Company, for use at our annual meeting of stockholders, or the Meeting, to be held at the Courtyard by Marriott—Norwalk, 474 Main Avenue, Norwalk, Connecticut 06851, on May 26, 2026, at 9:00 a.m., and at any postponements or adjournments of the Meeting. If you need directions to attend the Meeting and vote in person, you should contact the Company by telephone at (203) 975-7110. This Proxy Statement and the accompanying proxy card will first be mailed to stockholders on or about April 16, 2026.

Only holders of record of our Common Stock as of the close of business on April 2, 2026, the Record Date, will be entitled to notice of and to vote at the Meeting. As of the Record Date, we had 105,679,758 shares of our Common Stock outstanding. Each share of our Common Stock is entitled to one vote. We have no other class of voting securities issued and outstanding. The presence in person or by proxy of the holders of a majority of the outstanding shares of our Common Stock will be necessary to constitute a quorum for the transaction of business at the Meeting.

All shares of our Common Stock represented by properly executed proxies will be voted in accordance with the instructions indicated on such proxies unless such proxies previously have been revoked. If any proxies are signed and returned but do not contain voting instructions, the shares of our Common Stock represented by such proxies will be voted FOR the election of the three nominees for director listed below to serve until our annual meeting of stockholders in 2029 and until their successors are duly elected and qualified, FOR the approval of the First Amendment to the Silgan Holdings Inc. Second Amended and Restated 2004 Stock Incentive Plan, FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026, and FOR the approval, on an advisory basis, of the compensation of the Company’s named executive officers. We do not anticipate that any other matters will be brought before the Meeting. If any other matters properly come before the Meeting, the shares of our Common Stock represented by all properly executed proxies will be voted in accordance with the judgment of the persons named on such proxies. Shares of our Common Stock abstaining and shares of our Common Stock held in street name as to which a broker has not voted on some matters but has voted on other matters, or Broker Shares, will be included in determining whether a quorum exists at the Meeting. The New York Stock Exchange, or the NYSE, has adopted rules that eliminate broker discretionary voting for the election of directors and certain other corporate governance matters. Therefore, your broker is not able to vote on your behalf in any director election or with respect to the second and fourth matters specified in the Notice of Meeting, in each case without voting instructions from you.

Assuming that a quorum exists at the Meeting, approval of each of the first, second and third matters specified in the Notice of Meeting requires the affirmative vote of a majority of the votes cast at the Meeting, and approval, on an advisory basis, of the non-binding resolution with respect to the fourth matter specified in the

Notice of Meeting requires the affirmative vote of a majority of the votes cast at the Meeting. Stockholders may not cumulate their votes. Abstentions and Broker Shares that have not been voted with respect to the first, second, third or fourth matter specified in the Notice of Meeting will not be counted in determining the total number of votes cast for such matter or in determining whether such proposal has received the requisite number of affirmative votes.

You may revoke your proxy at any time before it is exercised at the Meeting by: (1) delivering to the Secretary of the Company a duly executed proxy bearing a later date; (2) filing a written notice of revocation with the Secretary of the Company; or (3) appearing at the Meeting and voting in person.

In addition to solicitations by mail, some of our directors, officers and employees may solicit proxies for the Meeting personally or by telephone without extra remuneration. We will also provide persons, banks, brokerage firms, custodians, nominees, fiduciaries and corporations holding shares in their names or in the names of nominees, which in either case are beneficially owned by others, with proxy materials for transmittal to such beneficial owners and will reimburse such record owners for their expenses in doing so. The Company will bear the costs of soliciting proxies.

THE COMPANY HEREBY UNDERTAKES TO PROVIDE WITHOUT CHARGE TO EACH PERSON TO WHOM A COPY OF THIS PROXY STATEMENT HAS BEEN DELIVERED, UPON THE WRITTEN REQUEST OF ANY SUCH PERSON, A COPY OF OUR ANNUAL REPORT ON FORM 10-K, INCLUDING THE FINANCIAL STATEMENTS AND THE FINANCIAL STATEMENT SCHEDULES THERETO, THAT HAS BEEN FILED WITH THE SECURITIES AND EXCHANGE COMMISSION, OR THE SEC, PURSUANT TO RULE 13a-1 UNDER THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED, FOR THE FISCAL YEAR ENDED DECEMBER 31, 2025.

Risk Oversight and Board Structure

Our Board of Directors as a whole is responsible for risk oversight for the Company. Our Board of Directors risk oversight process builds upon management’s assessment of the Company’s risks and processes for managing and mitigating such risks. At meetings of our Board of Directors, the executive officers of the Company regularly address and discuss with our Board of Directors risks of the Company and the manner in which the Company manages or mitigates its risks. While our Board of Directors has the ultimate responsibility for risk oversight for

6

the Company, our Board of Directors works in conjunction with its committees on certain aspects of its risk oversight responsibilities. In particular, our Audit Committee focuses on financial reporting risks and related controls and procedures. Our Compensation Committee strives to create compensation practices that do not encourage excessive levels of risk taking that would be inconsistent with the Company’s strategy and objectives. Our Nominating Committee assists our Board of Directors in identifying qualified candidates to become nominees for our Board of Directors of the Company.

Our corporate governance documents provide our Board of Directors with flexibility to select the appropriate leadership structure for the Company. In making leadership structure determinations, our Board of Directors considers many factors. At this time, each of the positions of Chairperson of the Board and Chief Executive Officer of the Company are held by different persons. Our Board of Directors has decided at this time to have different persons hold such positions largely due to the availability to the Company of multiple persons with many years of experience in the consumer goods packaging industry and extensive executive management experience with the Company. Our Chairperson of the Board has extensive experience in leading the Company, most recently having served as our Chief Executive Officer through August 2021, and has thirty years of experience in the packaging industry. With his substantial knowledge of the Company and the consumer goods packaging industry and extensive executive management experience, our Chairperson of the Board effectively leads our Board of Directors in its fundamental role of overseeing the business and affairs of the Company.

As part of each regularly scheduled quarterly meeting of our Board of Directors, our non-management Directors meet without the presence of management. These meetings allow our non-management Directors to discuss matters involving the Company without the presence of any member of management. Additionally, at each regularly scheduled quarterly meeting of our Board of Directors, our independent Directors meet without the presence of management or inside directors, allowing our independent Directors to discuss matters involving the Company without the presence of management or any inside director. At these meetings of our non-management Directors and these meetings of our independent Directors, no presiding director is appointed and each of the Directors in attendance at these meetings is given the opportunity to raise issues, make comments and express views.

Corporate Governance Guidelines and Business Ethics Code of Conduct

Our Board of Directors has adopted Corporate Governance Guidelines and a Code of Business Conduct and Ethics to comply with the New York Stock Exchange Listed Company Manual. The Corporate Governance Guidelines and Code of Business Conduct and Ethics are available on our website at www.silganholdings.com/corporatedocuments.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Stockholders Agreement

On November 28, 2022, the Company and R. Philip Silver, a founder of the Company who was a Director on our Board of Directors until his retirement on November 2, 2022, and D. Greg Horrigan, a founder of the Company who was a Director on our Board of Directors until his retirement on May 30, 2023, entered into the Stockholders Agreement, which amended and restated a previous stockholders agreement among such parties pursuant to which Messrs. Silver and Horrigan had the contractual right to nominate for election all Directors of the Company. Such previous stockholders agreement had replaced in its entirety a prior stockholders agreement entered into among Messrs. Silver and Horrigan, the Company and the other parties thereto at the time of the initial public offering of shares of Common Stock of the Company on February 14, 1997. Such prior stockholders agreement had replaced prior agreements entered into in December 1993 and in June 1989 among the parties thereto, including the founding stockholders of the Company. Under the Stockholders Agreement, the Group (as defined in the Stockholders Agreement and generally including Messrs. Silver and Horrigan and their affiliates, family members, trusts and estates) has the contractual right to nominate for election one individual as a member of the Board of Directors of the Company, provided that such nominee is either Mr. Silver or Mr. Horrigan, so long as the Group beneficially owns at least five percent of the outstanding Common Stock of the Company. As of the date of this Proxy Statement, the Group beneficially owns at least five percent of the outstanding shares of our Common Stock. The Stockholders Agreement terminates upon the death or disability of both of Messrs. Silver and Horrigan.

Other

In 2025, there were ordinary course transactions in which certain of our subsidiaries purchased certain raw materials from two companies, on one of which one of our Directors serves as an executive officer and on one of which one of our Directors serves as a director and, through his employer, as an investor. In each case, our Directors did not direct any such purchases. None of these transactions constituted a related party transaction that required approval by the Audit Committee.

Review, Approval or Ratification of Transactions with Related Persons

Pursuant to its written charter, the Audit Committee of the Board of Directors of the Company is required to approve any related party transactions that are required to be disclosed under applicable securities rules. In

13

evaluating any such proposed reportable transaction, the Audit Committee will consider the specific facts and circumstances of each transaction, which facts and circumstances will include the related person’s interest in the transaction, whether the transaction is being negotiated on an arm’s length basis, whether the terms of the transaction are fair to the Company and whether the terms of the transaction with the related person are no less favorable to the Company than could be obtained with a non-related third party under similar circumstances.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

In 2025, the Compensation Committee of our Board of Directors consisted of Mr. Abramson, Mr. Donovan, Mr. Lich, Ms. Miller (starting May 27, 2025), Ms. Cleland Nielsen and Ms. Ramdev, none of whom was an officer, former officer or employee of the Company. During 2025, none of our executive officers served as: (i) a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on the Compensation Committee of our Board of Directors, (ii) a director of another entity, one of whose executive officers served on the Compensation Committee of our Board of Directors, or (iii) a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on our Board of Directors.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

General

In this section of this Proxy Statement, we discuss the compensation for our executive officers, and we describe how we compensated our Chief Executive Officer, our Chief Financial Officer and our three other most highly compensated executive officers in 2025 based on total compensation, or, collectively, our Named Executive Officers. On November 4, 2025, the Board of Directors of the Company appointed Shawn C. Fabry as Executive Vice President and Chief Financial Officer of the Company effective November 6, 2025, succeeding Kimberly I. Ulmer in such position. On the same day, the Board of Directors of the Company appointed Ms. Ulmer as Senior Vice President and Chief Accounting Officer of the Company and Alexander G. Hutter as Senior Vice President, Strategy and Investor Relations of the Company, both effective November 6, 2025. Our Named Executive Officers for the fiscal year ended December 31, 2025 were:

Compensation Committee

The Compensation Committee is governed by a written charter approved by the Board of Directors of the Company. Pursuant to the Compensation Committee’s written charter, the Board of Directors of the Company has empowered the Compensation Committee to review and approve matters relating to the compensation of the Chief Executive Officer of the Company and all other executive officers of the Company. Pursuant to its charter, the Compensation Committee is also responsible for administering the Company’s equity compensation plans in which any executive officer of the Company participates (including the Stock Incentive Plan), including making awards and grants under such plans, setting performance goals for awards and grants as applicable under such plans, confirming performance levels as applicable in respect of performance awards made under such plans and interpreting and prescribing rules for administering such plans. The Compensation Committee also oversees and monitors the Company’s compensation policies, practices and programs for executive officers of the Company in light of the compensation philosophy and objectives of the Company. Additionally, the Compensation Committee reviews and makes recommendations to the Board of Directors of the Company relating to the compensation of Directors of the Company.

As required by its charter, the Compensation Committee must review and consider the outcome of any advisory vote of the stockholders of the Company at an annual meeting of stockholders regarding the compensation of the named executive officers of the Company. In addition, the Compensation Committee is required to review and assess the adequacy of its charter annually and recommend any proposed changes to its charter to the Board of Directors of the Company. In carrying out its responsibilities, the Compensation Committee has the authority, in its sole discretion, to retain and obtain advice of compensation consultants, legal counsel and other advisers, and the Company is required to provide funding therefor.

The Compensation Committee is currently comprised of six members, Leigh J. Abramson, William T. Donovan, Brad A. Lich, Shannon Miller, Fiona Cleland Nielsen and Niharika Ramdev. Mr. Abramson is the

18

Chairperson of the Compensation Committee. As required by its charter, all members of the Compensation Committee are (i) “independent directors” as required under the applicable rules of the NYSE, (ii) “outside directors” for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code, and (iii) “non-employee directors” for purposes of Rule 16b-3 of the Securities Exchange Act of 1934, as amended, or the Exchange Act.

In accordance with its charter, the Compensation Committee has reviewed and discussed with the Company’s management this Compensation Discussion and Analysis and has recommended to the Board of Directors of the Company that this Compensation Discussion and Analysis be included in this Proxy Statement. The Compensation Committee has also reviewed and approved the Compensation Committee Report included in this Proxy Statement as required by its charter.

Compensation Philosophy

The Compensation Committee strives to establish a compensation program for the executive officers of the Company that meets the following objectives:

The components of the compensation program for all executive officers of the Company are base salary, annual cash incentive bonus and equity-based compensation consisting of restricted stock units and performance awards of restricted stock units. The Compensation Committee believes that restricted stock units foster more balanced risk taking because they are more closely linked to direct ownership of stock than other forms of equity-based compensation. By including a combination of cash and at-risk equity compensation, the Compensation Committee believes that the Company’s executive compensation program is consistent with its business strategy and does not encourage its executive officers to take excessive risks that might threaten the long- term value of the Company. In addition, executive officers of the Company, other than Mr. Greenlee, our Chief Executive Officer, or CEO, receive other benefits typically provided to officers (such as retirement benefits and medical benefits), as further described below in “—Retirement and Other Benefits.”

2025 Advisory Vote on Compensation of Named Executive Officers

At our annual meeting of stockholders in 2025, pursuant to an advisory vote our stockholders overwhelmingly approved the compensation provided to our Named Executive Officers in 2024, with approximately 97% of the votes cast approving such compensation. The Compensation Committee reviewed and considered the results of the advisory vote of our stockholders in 2025 on the compensation of our Named Executive Officers and did not implement any changes as a result of such advisory vote of our stockholders.

Base Salary

The Compensation Committee endeavors to set base salaries for executive officers that enable the Company to attract and retain such officers and provide fair compensation taking into account relevant employment markets. The base salary for an individual executive officer is targeted such that the total compensation for such person is at a competitive level for individuals with similar responsibilities at manufacturing companies of a similar size, including packaging related companies.

19

Generally, each executive officer’s salary is reviewed on an annual basis by the Compensation Committee and may be adjusted based on:

In making such determinations for our Named Executive Officers, the Compensation Committee has generally reviewed publicly available compensation data including from the following manufacturing companies: AptarGroup, Inc.; Avery Dennison Corporation; Ball Corporation; Berry Global Group, Inc. (which was acquired in 2025 by Amcor plc); Clearwater Paper Corporation; Crown Holdings, Inc.; Graphic Packaging Holding Company; Greif, Inc.; O-I Glass, Inc.; Packaging Corporation of America; Pactiv Evergreen Inc.; Sealed Air Corporation; Sonoco Products Company; and Sylvamo Corp. Although the Compensation Committee does not use benchmarking to determine any element of compensation, the Compensation Committee believes that it is important from time to time to review compensation information from other appropriate companies to gain a general understanding of the competitiveness of the Company’s compensation program. For all other executive officers of the Company, the Compensation Committee reviews recommendations of the CEO of the Company and other information available to the Compensation Committee. For 2025, the salaries of Messrs. Greenlee, Hogan, Fabry and Hutter and Ms. Ulmer were increased 3.0% based on a general increase associated with inflation in the cost of living. In addition, the salaries of Messrs. Hogan, Fabry and Hutter and Ms. Ulmer were increased an additional 3.2%, 12.4%, 18.4% and 11.3%, respectively, for competitive market purposes. Additionally, on November 6, 2025, the salary of Mr. Fabry was increased from $425,000 to $550,000 in connection with his appointment as Executive Vice President and Chief Financial Officer of the Company and the salary of Mr. Hutter was increased from $375,000 to $450,000 in connection with his appointment as Senior Vice President, Strategy and Investor Relations of the Company.

Annual Cash Bonuses under Incentive Programs

All executive officers of the Company are eligible to receive annual cash bonuses, which are provided to enable the Company to attract and retain such officers and provide fair compensation taking into account responsibilities and relevant employment markets. Additionally, the Compensation Committee uses annual cash bonuses to reward executive officers for achieving the Company’s financial and non-financial goals. Executive officers of the Company are eligible for an annual cash bonus based on a percentage of their annual base salary that is determined generally based on the person’s responsibilities. In addition, the Compensation Committee may provide an executive officer with a cash bonus for a special assignment or in extraordinary circumstances where warranted.

The table below sets forth summary information for 2025 for our Named Executive Officers with regard to the incentive plan or program in which such individual participated, the bonus range, target bonus award and maximum bonus award as a percentage of salary for each such individual, the actual bonus award for each such individual and the actual bonus award as a percentage of salary for each such individual.

2025 Annual Cash Bonuses under Incentive Programs

21

Annual cash bonuses are paid to Mr. Greenlee under the Company’s Senior Executive Performance Plan, as amended, or the Senior Executive Performance Plan. For 2025, Mr. Greenlee was the only participant in the Senior Executive Performance Plan. Pursuant to the Senior Executive Performance Plan, Mr. Greenlee could be eligible for an annual cash bonus of up to 200% of his annual base salary, with such maximum amount of Mr. Greenlee’s annual target cash bonus being set annually by the Compensation Committee. For 2025, the Compensation Committee evaluated competitive data and approved a maximum annual target cash bonus for Mr. Greenlee of 125% of his annual base salary. In setting the maximum amount of the annual target cash bonus for Mr. Greenlee, the Compensation Committee based its determination on its objective of retaining Mr. Greenlee and providing him with fair overall annual cash compensation taking into account his responsibilities and relevant employment markets. The maximum amount of the annual target cash bonus for Mr. Greenlee was increased by the Compensation Committee from 100% in 2024 to 125% in 2025 based on a review of competitive compensation data by the Compensation Committee in 2024.

For 2025, Messrs. Chevrier and Hogan and Ms. Ulmer and, for the period November 6, 2025 through December 31, 2025, Messrs. Fabry and Hutter participated in a bonus program, or the Holdings Executive Officer Program, which was approved by the Compensation Committee and under which annual cash bonuses were calculated on the same basis as under the Senior Executive Performance Plan. Messrs. Fabry and Hutter were approved to participate in the Holdings Executive Officer Program for the period November 6, 2025 through December 31, 2025 in connection with their appointments as Executive Vice President and Chief Financial Officer and Senior Vice President, Strategy and Investor Relations of the Company, respectively, on November 6, 2025. For 2025, the Compensation Committee approved maximum annual target cash bonuses for each of Messrs. Chevrier and Hogan and Ms. Ulmer in an amount of 75% of their respective annual base salaries and, effective November 6, 2025, maximum annual target cash bonuses for each of Messrs. Fabry and Hutter in an amount of 50% of their respective annual base salaries received for the period November 6, 2025 through December 31, 2025. For the period January 1, 2025 through November 5, 2025, Messrs. Fabry and Hutter participated in the Holdings Officer Program, as further described below.

Under the Senior Executive Performance Plan and the Holdings Executive Officer Program, at the beginning of each year, the Compensation Committee establishes a performance goal and a performance goal target for the Company for that year. Following such year, the Compensation Committee confirms the extent to which the performance goal target for such year was met. If the performance goal target was met, then the participants under this plan and this program would receive the annual target cash bonus for which he was eligible for that year. If the performance goal target was not met, then the participant would receive a pro rata amount of the annual target cash bonus for which he was eligible for that year. For 2025, the performance goal established by the Compensation Committee under this plan and this program was the net income before interest, taxes, depreciation and amortization and rationalization charges, acquisition termination fees (net of related costs), costs attributable to announced acquisitions, the impact from any foreign currency devaluations and other pension income (expense) from U.S. pension plans (Adjusted EBITDA) of the Company, subject to further adjustment as determined by the Compensation Committee for acquisitions and/or divestitures completed during 2025 and unusual gains and unusual losses, and the performance goal target for the annual target cash bonus was the Adjusted EBITDA level of the Company for 2024 ($881.5 million), with the amount of the annual bonus under this plan and this program calculated based on the following formula:

X multiplied by the Company’s Adjusted EBITDA for 2025; with X being equal to a percentage, the numerator of which is the maximum annual target cash bonus for a particular person and the denominator of which is the Company’s Adjusted EBITDA for 2024.

The Company’s Adjusted EBITDA for 2025 was 977.8 million, or 110.9% of the Company’s Adjusted EBITDA for 2024. Therefore, each of Messrs. Greenlee, Chevrier and Hogan and Ms. Ulmer was entitled to an annual cash bonus for 2025 equal to 100% of his or her annual target cash bonus for 2025, or 125%, 75%, 75% and 75% of their annual base salaries in 2025, respectively. In addition, each of Messrs. Fabry and Hutter was

22

entitled to a cash bonus for the period November 6, 2025 through December 31, 2025 equal to 100% of his annual target cash bonus for such period, or 50% of their annual base salaries received for such period.

For 2026, Mr. Greenlee is the only participant in the Senior Executive Performance Plan. Pursuant to the Senior Executive Performance Plan, Mr. Greenlee could be eligible for an annual cash bonus of up to 200% of his annual base salary, with the maximum amount of Mr. Greenlee’s annual target cash bonus being set annually by the Compensation Committee. For 2026, the Compensation Committee evaluated competitive compensation data and approved a maximum annual target cash bonus for Mr. Greenlee of 125% of his annual base salary. In setting the maximum amount of the annual target cash bonus for Mr. Greenlee, the Compensation Committee bases its determination on its objective of retaining Mr. Greenlee and providing him with fair overall annual cash compensation taking into account his responsibilities and relevant employment markets.

For 2026, the Compensation Committee set the performance goal for Mr. Greenlee under the Senior Executive Performance Plan as the Adjusted EBITDA of the Company, subject to further adjustment as determined by the Compensation Committee for acquisitions and/or divestitures completed during 2026 and unusual gains and unusual losses, and the performance goal target for the maximum amount of his annual bonus as the Adjusted EBITDA of the Company in 2025, with the manner for calculating the amount of his annual bonus being the same as in 2025. If the performance goal target is met, then Mr. Greenlee will receive his annual target cash bonus for which he is eligible, or 125% of his annual base salary. If the performance goal target is not met, then Mr. Greenlee will receive a pro rata amount of his annual target cash bonus for which he is eligible. In setting the performance goal under the Senior Executive Performance Plan, the Compensation Committee chose net income before interest, taxes, depreciation and amortization and rationalization charges of the Company because it believes that it is an important and accepted measure of performance of the Company, and the Compensation Committee decided to exclude acquisition termination fees (net of related costs), costs attributable to announced acquisitions, the impact from any foreign currency devaluations and other pension income (expense) for U.S. pension plans from such calculation because such items are generally non-recurring and/or not indicative of the Company’s operating results. For 2026, the Compensation Committee approved an annual cash bonus program for each of Messrs. Chevrier, Hogan, Fabry and Hutter pursuant to which each of them is eligible to receive a maximum annual target cash bonus in an amount of 75%, 75%, 75% and 50%, respectively, of his annual base salary received in 2026, with the amount of such annual cash bonus being calculated on the same basis that an annual cash bonus is calculated for Mr. Greenlee for 2026 under the Senior Executive Performance Plan.

The Compensation Committee has established annual bonus programs applicable to Messrs. Greenlee, Chevrier, Hogan and Fabry, or the Holdings Executives, that are different from the annual cash bonus programs applicable to the other executive officers of the Company because they assist the Compensation Committee in establishing the annual cash bonus programs for the other executive officers of the Company, including setting financial and non-financial goals under such programs and determining whether goals were met under such programs. The Compensation Committee believes it is important that it receive an unbiased view from members of top management in establishing such programs, and believes that the best way to accomplish this objective is to not have those assessing such programs participate in them so that these individuals have no conflict of interest. Additionally, the objectives of the annual cash bonus programs for Messrs. Greenlee, Chevrier, Hogan, Fabry and Hutter are to retain such individuals and provide them with fair overall annual compensation taking into account relevant employment markets, and such programs are not meant primarily as an award for short-term financial performance. The Compensation Committee believes that it is more advantageous for the Company that Messrs. Greenlee, Chevrier, Hogan, Fabry and Hutter focus more on long-term creation of stockholder value rather than short-term goals. Accordingly, the Compensation Committee establishes a performance goal target with respect to annual bonuses payable to Messrs. Greenlee, Chevrier, Hogan, Fabry and Hutter that, although not certain, should be attainable. For 2026, the Compensation Committee approved an annual cash bonus program for Ms. Ulmer pursuant to the Holdings Officer Program, as further described below, and established that she is eligible to receive an annual target cash bonus in an amount of 50% of her annual base salary received in 2026.

23

For the period January 1, 2025 through November 5, 2025, Messrs. Fabry and Hutter participated in an incentive program for the other officers of the Company located at its corporate office, or the Holdings Officer Program. Annual cash bonuses are paid to participants in the Holdings Officer Program based upon the achievement of a certain financial goal and certain non-financial goals established by the Holdings Executives and reviewed by the Compensation Committee. The Compensation Committee generally believes that a majority of the annual cash bonuses payable under the Holdings Officer Program should be based on a financial goal. The financial goal for the Holdings Officer Program is established at the beginning of the year by the Holdings Executives and reviewed and approved by the Compensation Committee. The remaining portion of annual cash bonuses payable under the Holdings Officer Program is based on non-financial goals established by the Holdings Executives and reviewed by the Compensation Committee. In determining the levels of achievement for the non-financial goals, the Compensation Committee relies upon the subjective evaluation of the Holdings Executives, as well as their own observations and views obtained during the year. Participants in the Holdings Officer Program can receive up to two times their target bonus if financial and non-financial goals are far exceeded. Generally, however, the Compensation Committee is of the view that non-financial goals, by their nature, are extremely hard to attain at a level warranting two times payment of the amount of the target bonus applicable to such non-financial goals, and therefore realistically participants can expect to receive generally between approximately 50% and 150% of the amount of their target bonus applicable to such non-financial goals.

Under the Holdings Officer Program, as approved by the Compensation Committee, each of Messrs. Fabry and Hutter was eligible for a target bonus of 30% of his annual salary received for the period January 1, 2025 through November 5, 2025. The Compensation Committee approved 75% of each of Messrs. Fabry’s and Hutter’s target bonus of 30% of his salary received for the period January 1, 2025 through November 5, 2025, or 22.5% of his salary received for the period January 1, 2025 through November 5, 2025, being based upon the achievement of a financial goal by the Company for 2025 and 25% of each of Messrs. Fabry’s and Hutter’s target bonus of 30% of his annual salary, or 7.5% of his salary received for the period January 1, 2025 through November 5, 2025, being based upon the achievement of non-financial goals for 2025. The financial goal for the Company for 2025, as approved by the Compensation Committee, was its 2025 budgeted net income before interest and taxes and rationalization charges, the foreign currency impact from certain intercompany agreements, the impact from any foreign currency devaluations, costs attributed to announced acquisitions, other pension income (expense) for U.S. pension plans and acquired intangible asset amortization expense and subject to further adjustment as determined by the Compensation Committee for unusual gains, unusual losses, unusual business impacts and acquisitions and/or divestitures completed during 2025 (Adjusted EBIT). The budgeted Adjusted EBIT for 2025 of the Company was compared to the actual Adjusted EBIT for 2025 of the Company. If the actual Adjusted EBIT of the Company for 2025 was between 96% and 104% of the budgeted Adjusted EBIT of the Company for 2025, then each of Messrs. Fabry and Hutter would have been entitled to 100% of the portion of his bonus payable based upon the achievement of a financial goal (i.e., 22.5% of his salary received for the period January 1, 2025 through November 5, 2025). If the actual Adjusted EBIT of the Company for 2025 was less than 96% (but more than 88%) or greater than 104% (up to 112%) of the budgeted Adjusted EBIT for 2025, then each of Messrs. Fabry’s and Hutter’s bonus would have been adjusted on a pro rata basis on a sliding scale based on the chart below, as follows:

The non-financial goals under the Holdings Officer Program for 2025, as approved by the Compensation Committee, consisted of certain corporate initiatives and certain other initiatives for corporate development,

24

finance, tax, legal and investor relations. For the portion of each of Messrs. Fabry’s and Hutter’s bonus payable based upon non-financial goals (i.e., 25% of his target bonus of 30% of his salary received for the period January 1, 2025 through November 5, 2025, or 7.5% of his salary received for the period January 1, 2025 through November 5, 2025), the Holdings Executives determined the percentage (based on 100%) that such non-financial goals were met and recommended such percentage to the Compensation Committee for their approval. The approved percentage is then multiplied by such portion of the target bonus payable based upon non-financial goals and such amount is added to the amount of the bonus payable for the financial goal to determine the total bonus payable for 2025.

In 2025, the Company achieved 93.4% of its budgeted Adjusted EBIT, and Messrs. Fabry and Hutter achieved 132% and 117% of his non-financial goals, respectively.

Based on the foregoing, the bonus amount payable to Mr. Fabry under the Holdings Officer Program for the period January 1, 2025 through November 5, 2025 based upon the achievement of a financial goal by the Company in 2025 was 15.1% of his salary received for the period January 1, 2025 through November 5, 2025 in accordance with the chart above. The bonus amount payable to Mr. Fabry under the Holdings Officer Program for the period January 1, 2025 through November 5, 2025 based upon the achievement of non-financial goals in 2025 was 9.9% of his salary received for the period January 1, 2025 through November 5, 2025, calculated as follows:

132% x 7.5% = 9.9%

Therefore, Mr. Fabry’s bonus under the Holdings Officer Program for the period January 1, 2025 through November 5, 2025 was the sum of the percentage payable for the financial goal and the percentage payable for the non-financial goals, or 25.0% (15.1% plus 9.9%) of his salary received for the period January 1, 2025 through November 5, 2025 (which equates to approximately 83.45% of his target bonus of 30% of his annual salary received for the period January 1, 2025 through November 5, 2025). On a combined basis, for 2025 Mr. Fabry received an aggregate annual cash bonus under the Holdings Executive Officer Program and Holdings Officer Program as described above of 29.8% of his annual base salary in 2025.

Based on the foregoing, the bonus amount payable to Mr. Hutter under the Holdings Officer Program for the period January 1, 2025 through November 5, 2025 based upon the achievement of a financial goal by the Company in 2025 was 15.1% of his salary received for the period January 1, 2025 through November 5, 2025 in accordance with the chart above. The bonus amount payable to Mr. Hutter under the Holdings Officer Program for the period January 1, 2025 through November 5, 2025 based upon the achievement of non-financial goals in 2025 was 8.8% of his salary received for the period January 1, 2025 through November 5, 2025, calculated as follows:

117% x 7.5% = 8.8%

Therefore, Mr. Hutter’s bonus under the Holdings Officer Program for the period January 1, 2025 through November 5, 2025 was the sum of the percentage payable for the financial goal and the percentage payable for the non-financial goals, or 23.9% (15.1% plus 8.8%) of his salary received for the period January 1, 2025 through November 5, 2025 (which equates to approximately 79.70% of his target bonus of 30% of his annual salary received for the period January 1, 2025 through November 5, 2025). On a combined basis, for 2025 Mr. Hutter received an aggregate annual cash bonus under the Holdings Executive Officer Program and Holdings Officer Program as described above of 28.6% of his annual base salary in 2025.

Annual cash bonuses are paid to participants in the incentive programs of the Company’s business operations based upon the achievement of certain financial goals and non-financial goals. Participants in those programs are viewed on a team basis for purposes of annual cash bonuses and establishing financial and non-financial goals. The Compensation Committee generally believes that a majority of the annual cash bonuses

25

payable to managers of the Company’s business operations should be based on a financial goal. The financial goals for the Company’s business operations for a given year are established at the beginning of such year by the Holdings Executives and reviewed by the Compensation Committee. The remaining portion of the annual cash bonuses for the managers of the Company’s business operations is based upon non-financial goals. Such non-financial goals for each of the Company’s business operations for a given year are established at the beginning of the year by the Holdings Executives in conjunction with the managers of such business operations and reviewed by the Compensation Committee. Such non-financial goals are generally items that both the Holdings Executives and the managers of the particular business operation desire additional attention during the year. In determining levels of achievement for non-financial goals, the Compensation Committee relies upon the subjective evaluations of the Holdings Executives, as well as their own observations of the Company’s business operations obtained from the reports given by the managers of such business operations at regular quarterly meetings of the Board of Directors of the Company. Participants in the incentive programs of the Company’s business operations can receive up to two times their target bonus amount if financial and non-financial goals of the applicable business operations are far exceeded. Generally, however, the Compensation Committee is of the view that non-financial goals, by their nature, are extremely hard to attain at a level warranting two times payment of the amount of the target bonus applicable to such non-financial goals, and therefore realistically participants can expect to receive generally between approximately 50% and 150% of the amount of their target bonus applicable to such non-financial goals.

Equity Based Compensation

The Compensation Committee provides equity based compensation to executive officers of the Company and its subsidiaries through awards that achieve the Compensation Committee’s objectives of attracting and retaining officers and other key employees and aligning their interests with those of the stockholders of the Company. The purpose of the Company’s equity based compensation plans (including the Stock Incentive Plan), or the Plans, is to promote the long-term success of the Company and the creation of stockholder value by (i) encouraging the attraction and retention of directors and officers and other key employees and (ii) linking directors and officers and other key employees of the Company directly to stockholder interests through stock ownership and appreciation.

The Compensation Committee is responsible for administering the Plans, including determining recipients of awards, approving awards, setting the terms and conditions of awards, and interpreting and prescribing rules for administering the Plans. The Stock Incentive Plan allows the Compensation Committee to grant awards of stock options, stock appreciation rights, restricted stock, restricted stock units and performance awards.

From 2005 to 2025, the Compensation Committee granted only restricted stock units and performance awards for restricted stock units under the Plans. At this time, the Compensation Committee has determined to grant only restricted stock units and performance awards for restricted stock units because it believes that restricted stock units are more closely linked to ownership of stock as compared to stock options and stock appreciation rights, thereby aligning the interests of award recipients more closely with those of our stockholders.

Under the Plans, the Compensation Committee generally granted (i) restricted stock units to newly hired individuals (including from acquisitions) and to individuals who are promoted and (ii) performance awards annually to current officers and other key employees, all as described below. In addition, the Compensation Committee may grant awards under the Plans to officers and other key employees of the Company and its subsidiaries at other times and for other purposes.

To attract new officers and other key employees (including from acquisitions), the Compensation Committee will grant restricted stock units to such new individuals, which generally will vest ratably over a five-year period or all at once in a single installment at least one year from the date of grant. The number of restricted stock units that are granted to an individual will be determined by the Compensation Committee generally on the basis of what it believes is necessary to hire and retain such individual, taking into account the salary and bonus

26

offered to such individual and the total nominal value of such restricted stock units. The Compensation Committee may also grant restricted stock units during the course of the year to officers who are promoted, largely on the basis of the nominal value of unvested restricted stock units of such individuals as compared to a targeted multiple of such individual’s new annual base salary. The primary purpose of such equity awards is retention of the individual, and therefore these restricted stock units will generally vest ratably over a five-year period. Typically, the Compensation Committee makes grants to newly hired or promoted individuals on only up to one business day during a fiscal quarter, generally at a regularly scheduled meeting of the Compensation Committee which generally follows the issuance by the Company of its quarterly earnings release. As a result, the general practice of the Compensation Committee is to make grants on up to four dates during each year and, in addition, as applicable, in connection with certain acquisitions. The Compensation Committee does not grant awards under the Plans in anticipation of the release of material, nonpublic information or time the release of material, nonpublic information based on award grant dates.

Additionally, to retain current officers and other key employees, the Compensation Committee annually reviews the nominal value of unvested restricted stock units of such persons. For each officer and other key employee of the Company, the Compensation Committee targets a multiple of such person’s annual base salary (plus, in the case of the CEO, targeted annual bonus) as the level of the nominal value of unvested restricted stock units for each such person. The multiple for each individual is determined on the basis of the individual’s anticipated long-term contribution to the Company. Within the first ninety days of each year, the Compensation Committee will fix and establish performance criteria for that year for potential grants of performance awards of restricted stock units in the following year. The minimum level of performance required to be attained for grants to be made in the following year is set by the Compensation Committee at a level that, although not certain, should be attainable because the primary purpose of these grants is retention. For grants made in 2025, the Compensation Committee established in February 2024 the Company’s Adjusted EBITDA, subject to adjustment as determined by the Compensation Committee for unusual items and acquisitions and divestitures completed in 2024, as the performance criteria and the minimum level of performance by the Company for 2024 as 75% of the Company’s Adjusted EBITDA level in 2023. At the time the performance criteria is set for a particular year, the Compensation Committee approves a maximum number of restricted stock units that may be granted to each individual in the following year if the Company attains the minimum level of performance. Then, following the end of a particular year, if the Company attains the minimum level of performance for that year, the Compensation Committee will review the nominal value of the unvested restricted stock units previously granted to an individual and compare this to the individual’s target multiple of salary (plus, in the case of the CEO, bonus). For 2025, the target multiple for Mr. Greenlee was three times his salary and bonus. For 2025, the target multiple for each of Messrs. Chevrier, Hogan, Fabry and Hutter and Ms. Ulmer was three times such person’s salary. Generally, at its regularly scheduled meeting during the first quarter, the Compensation Committee will then consider performance awards of restricted stock units to individuals whose aggregate nominal value of unvested restricted stock units is less than their target multiple of salary (plus, in the case of the CEO, bonus) so that the total nominal value of unvested restricted stock units approximates their target multiple of salary (plus, in the case of the CEO, bonus). Any such restricted stock units so granted will generally vest ratably over a five-year period. In 2025, Messrs. Greenlee, Chevrier, Hogan, Fabry and Hutter and Ms. Ulmer were granted performance awards for 70,700, 42,000, 16,900, 11,400, 10,500 and 16,900 restricted stock units, respectively, on the basis described in this paragraph, since the Company achieved the minimum level of performance established by the Compensation Committee for such grants.

In addition to the performance awards granted annually as described in the paragraph above, the Compensation Committee has granted performance awards for restricted stock units from time to time to Messrs. Greenlee, Chevrier, Hogan, Fabry and Hutter and Ms. Ulmer to supplement their total compensation. These grants generally vest ratably over a period of at least three years from the date of grant or all at once in a single installment at least three years from the date of grant. The primary purpose of these grants is to provide additional long-term compensation to such executive officers to keep them at competitive compensation levels and to do so in a manner that further augments the retention of such executive officers. These grants have been subject to the attainment of performance criteria as established by the Compensation Committee and are

27

forfeitable in the event the Company does not attain such performance criteria. The performance criteria for such grants has generally been the Adjusted EBITDA of the Company for the year of or following such grant, subject to adjustments as determined by the Compensation Committee for unusual items and acquisitions or divestures completed in the applicable year, and the minimum level of performance required for such grant has been 75% of the Company’s prior year Adjusted EBITDA level. In May 2023, on the basis described in this paragraph, Messrs. Greenlee and Hogan and Ms. Ulmer were granted performance awards for 70,000, 10,500 and 25,000 restricted stock units, respectively, which, since the Company attained the applicable performance criteria for these grants, vest ratably over a three year period beginning March 1, 2024. In March 2024, on the basis described in this paragraph, Messrs. Greenlee and Hogan and Ms. Ulmer were granted performance awards for 66,000, 17,000 and 6,500 restricted stock units, respectively, which, since the Company attained the applicable performance criteria for 2024, vest ratably over a three year period from the date of grant. In March 2025, on the basis described in this paragraph, Messrs. Greenlee, Chevrier and Hogan and Ms. Ulmer were granted performance awards for 105,000, 48,000, 8,800 and 9,200 restricted stock units, respectively, which, since the Company attained the applicable performance criteria for 2025, vest ratably over a three year period beginning March 1, 2026. In March 2025, on the basis described in this paragraph, Messrs. Fabry and Hutter were each granted performance awards for 25,000 restricted stock units, which, since the Company attained the applicable performance criteria for 2025, vest all at once on March 1, 2030. The Compensation Committee views all these performance awards as additional compensation for the applicable individual spread evenly over the entire vesting period, rather than being entirely allocated to the year of grant (as required under SEC reporting rules).

For example, in the case of Mr. Greenlee, the Compensation Committee views the compensation attributable to the performance award of 70,000 restricted stock units granted to him on May 30, 2023 over the three-year vesting period of such performance award, the compensation attributable to the performance award of 66,000 restricted stock units granted to him on March 1, 2024 over the three-year vesting period of such performance award, and the compensation attributable to the performance award of 105,000 restricted stock units granted to him on March 1, 2025 over the three-year vesting period of such performance award. Therefore, the Compensation Committee allocates the compensation attributable to such awards equally over each year of the applicable vesting period as opposed to all in one year as the Summary Compensation Table requires. Accordingly, the Compensation Committee views the performance award of 70,000 restricted stock units granted to Mr. Greenlee on May 30, 2023 as additional compensation annually of $1,079,750 (using the grant date fair value used in the Summary Compensation Table) for Mr. Greenlee over the three-year vesting period of such performance award, the performance award of 66,000 restricted stock units granted to Mr. Greenlee on March 1, 2024 as additional compensation annually of $965,910 (using the grant date fair value used in the Summary Compensation Table) for Mr. Greenlee over the three-year vesting period of such performance award, and the performance award of 105,000 restricted stock units granted to Mr. Greenlee on March 1, 2025 as additional compensation annually of $1,890,000 (using the grant date fair value used in the Summary Compensation Table) for Mr. Greenlee over the three-year vesting period of such performance award, in each case in contrast to the total amount being recognized all in one year as required in the Summary Compensation Table.

Restricted stock units granted under the Plans carry with them the right to receive dividend equivalents in an amount equal to all cash dividends paid on one share of Common Stock of the Company for each restricted stock unit while such restricted stock unit is outstanding and until such restricted stock unit vests. Such dividend equivalents for a restricted stock unit are accrued as dividends and are paid to the individual only upon the vesting of such restricted stock unit. The Compensation Committee added dividend equivalent rights to restricted stock units to further align the interests of officers and other key employees of the Company and its subsidiaries with those of the stockholders of the Company.

Stock Ownership Guidelines

The Company adopted stock ownership guidelines applicable to our Directors at five times the $110,000 annual cash retainer payable to Directors, our CEO at six times our CEO’s annual base salary, our other Named Executive Officers at three times his or her annual base salary and our other executive officers at one times his or her annual base salary. These guidelines apply to all equity holdings and are subject to a transition period of five years for newly elected Directors and executive officers.

28

Retirement and Other Benefits

The Company also provides pension benefits to certain of its longer tenured executive officers and 401(k), supplemental retirement, medical, disability, life insurance and other benefits to most of its executive officers for purposes of retention.

The Company does not provide retirement benefits to Messrs. Greenlee and Chevrier or certain other benefits to Mr. Greenlee. Messrs. Greenlee and Chevrier are eligible for group term life insurance benefits on the same general basis as all other U.S. employees of the Company and its subsidiaries and can make elective contributions to the 401(k) plan but do not receive any matching contributions from the Company. Additionally, Mr. Greenlee can participate in the medical benefits provided he pays 100% of his premiums. This approach allows them to provide unbiased assistance to the Compensation Committee in its oversight and review of these benefits.

Each of Messrs. Hogan, Fabry and Hutter and Ms. Ulmer are eligible to participate in (i) the Silgan Containers Retirement Savings Plan, or the Silgan Containers 401(k) Plan (a 401(k) plan intended to be qualified under Section 401(a) of the Code, in which individuals can elect to participate and which provides for matching contributions), (ii) the Silgan Containers Supplemental Executive Retirement Plan, as amended, or the Silgan Containers Supplemental Plan (a non-qualified defined contribution plan that provides for contributions on behalf of participating individuals which are intended to make up for benefits not payable under the pension and 401(k) plans because of limits imposed by the Code), and (iii) medical benefits and group life insurance benefits generally available to all salaried employees of the Company and Silgan Containers on the same basis as they are available to all other salaried employees of the Company and Silgan Containers. In addition, Mr. Hogan and Ms. Ulmer participate in the Silgan Containers Pension Plan for Salaried Employees, or the Silgan Containers Pension Plan, a defined benefit plan intended to be qualified under Section 401(a) of the Code, which has been closed to new participants since January 1, 2007.

Perquisites and Other Personal Benefits

Generally, the Company does not provide its executive officers with any perquisites or other personal benefits.

Employment Agreements

Mr. Greenlee is entitled to a severance benefit, as provided in an employment letter from the Company dated October 1, 2007, if his employment is terminated by the Company without cause, in an amount equal to the sum of (i) his then current annual salary plus (ii) his annual bonus, calculated at the then current maximum bonus amount payable to him as previously approved by the Compensation Committee.

Mr. Chevrier is entitled to a severance benefit, as provided in an officer agreement with the Company, dated February 3, 2025, if his employment is terminated by the Company without cause, in an amount equal to the sum of (i) his then current annual salary plus (ii) his annual bonus, calculated at the then current target bonus amount payable to him as previously approved by the Compensation Committee.

Mr. Fabry is entitled to a severance benefit, as provided in an officer agreement with the Company, dated August 1, 2023, if his employment is terminated by the Company without cause, in an amount equal to the sum of (i) his then current annual salary plus (ii) his annual bonus, calculated at the then current target bonus amount payable to him as previously approved by the Compensation Committee.

Mr. Hutter is entitled to a severance benefit, as provided in an officer agreement with the Company, dated November 6, 2025, if his employment is terminated by the Company without cause, in an amount equal to his then current annual salary.

30

Tax Deductibility of Incentive Compensation

As a general matter, the Compensation Committee intends to design a compensation program for the executive officers of the Company that meets the objectives set forth above, even if such compensation is not fully deductible by the Company for federal income tax purposes. For the year ended December 31, 2025, Section 162(m) of the Code limited the Company’s deduction to $1 million for annual compensation paid to our Named Executive Officers that are considered “covered employees”, as defined in Section 162(m) of the Code. While the Compensation Committee considers tax implications to the Company as factors when designing our executive compensation program, they are not the only factors considered as important in our executive compensation program. In addition, the Compensation Committee reserves the right to establish compensation arrangements that may not be fully tax deductible under the Code or other applicable tax laws.

31

Compensation Committee Report

The Compensation Committee has reviewed and discussed the section of this Proxy Statement titled “Compensation Discussion and Analysis” with management of the Company. Based on such review and discussion, the Compensation Committee recommended to the Board of Directors of the Company that the “Compensation Discussion and Analysis” be included in the Proxy Statement of the Company for its 2026 annual meeting of stockholders.

32

Summary Compensation Table

The table below summarizes the total compensation for the fiscal years ended December 31, 2025, 2024 and 2023 paid to or earned by our Named Executive Officers, consisting of those individuals who served as Chief Executive Officer or Chief Financial Officer of the Company during 2025 and the three most highly compensated executive officers of the Company for 2025 (other than those who served as CEO or CFO during 2025).

Total Compensation with Supplemental Stock Awards Allocated Over Vesting Period

The following table, which is not required under the SEC’s rules and is not a substitute for any of the tables required under the SEC’s rules, provides an alternative presentation of the total compensation of our Named Executive Officers by adjusting the total compensation amounts in column (j) of the Summary Compensation Table to reflect the Compensation Committee’s view on the compensation attributable to Supplemental Stock Awards. The amounts in the column titled “Total Compensation with Supplemental Stock Awards Allocated Over Vesting Period” consist of the total of columns (c), (d), (e), (f), (g), (h) and (i) of the Summary Compensation Table for the corresponding year, with the amount in column (e) for stock awards being adjusted in respect of Supplemental Stock Awards to include compensation attributable to such Supplemental Stock Awards spread evenly over the entire vesting period of such Supplemental Stock Awards. This presentation is consistent with the Compensation Committee’s view on the compensation attributable to Supplemental Stock Awards, in contrast to including the full amounts of the compensation attributable to such Supplemental Stock Awards in the year of grant as reflected in columns (e) and (j) of the Summary Compensation Table. For further information on equity based compensation provided by the Company, you should read the sections in this Proxy Statement titled “Executive Compensation—Compensation Discussion and Analysis—Equity Based Compensation” and “Executive Compensation—Summary Compensation Table.”

Grants of Plan Based Awards

The following table provides information concerning each grant of an award made to our Named Executive Officers in the fiscal year ended December 31, 2025 under any plan. All awards under non-equity incentive plans were paid under the incentive plans or programs described in the section of this Proxy Statement titled “Executive Compensation— Compensation Discussion and Analysis—Annual Cash Bonuses under Incentive Programs.” All equity awards were made under the Stock Incentive Plan and were all performance based awards that were granted consistent with the Compensation Committee’s practices for equity based compensation as described in the section of this Proxy Statement titled “Executive Compensation—Compensation Discussion and Analysis—Equity Based Compensation.”

Option Exercises and Stock Vested

The following table provides information concerning each exercise of stock options and each vesting of restricted stock units during the fiscal year ended December 31, 2025 for each of our Named Executive Officers on an aggregated basis.

Pension Benefits

The following table shows the present value of accumulated benefits payable to each of our Named Executive Officers, including the number of years of service credited to each such Named Executive Officer, under the Silgan Containers Pension Plan. The basic terms of this plan are generally described below. Each of Messrs. Greenlee, Chevrier, Fabry and Hutter does not participate in and is not eligible to participate in any pension plan of the Company or any of its subsidiaries.

42

Benefits under the Silgan Containers Pension Plan are based on the participant’s average rate of base pay (or salary) over the final three years of employment, with increases to a participant’s rate of base pay following January 1, 2007 (or the first January 1 the participant earned base pay, if later) capped at 3% per year for purposes of the Silgan Containers Pension Plan. The amount of average base pay taken into account for any year is limited by Section 401(a)(17) of the Code, which imposes a cap of $350,000 (to be indexed for inflation) on compensation taken into account for 2025. Benefits under the Silgan Containers Pension Plan are not subject to any deduction for social security or other offset amounts. The Silgan Containers Pension Plan was amended in 2006 to provide that salaried employees hired after 2006 are no longer eligible to participate in the Silgan Containers Pension Plan.

Non-Qualified Deferred Compensation

The following table provides information with respect to each defined contribution or other plan that provides for the deferral of compensation on a basis that is not tax qualified for each of our Named Executive Officers. Messrs. Hogan and Fabry and Ms. Ulmer currently participate in the Silgan Containers Supplemental Plan. Mr. Hutter is eligible to participate in the Silgan Containers Supplemental Plan. Each of Messrs. Greenlee and Chevrier does not participate in any non-qualified deferred compensation plan of the Company or any of its subsidiaries. You should read the section of this Proxy Statement titled “Executive Compensation—Compensation Discussion and Analysis—Retirement and Other Benefits” above for further information regarding these plans.

Potential Payments Upon Termination or Change of Control

Potential Payments Upon Termination

In the event that a Named Executive Officer’s employment is terminated for any reason, such person is entitled to receive amounts earned through the date of termination, including salary, amounts contributed under the applicable 401(k) plan (including, to the extent applicable, any vested contributions made by the Company or a subsidiary of the Company), unused vacation pay and, in the case of Mr. Hogan and Ms. Ulmer, accrued and vested benefits under and pursuant to the Silgan Containers Pension Plan and, in the case of Messrs. Hogan, Fabry and Hutter and Ms. Ulmer, accrued and vested benefits under and pursuant to the Silgan Containers Supplemental Plan.

Upon termination of employment for any reason, all restricted stock units of a Named Executive Officer that are unvested are forfeited except as described in the section below titled “Potential Payments Upon Change of Control.” In addition, if such termination is not voluntary, such person is entitled to receive a pro rata amount of his bonus for the year in which such person is terminated.

In addition to the foregoing, each of our Named Executive Officers is entitled to the following in the event that his or her employment is terminated without cause:

The following table sets forth the potential payments to each Named Executive Officer if such officer had been terminated without cause on December 31, 2025.

Potential Payments Upon Change of Control

The Company does not have any agreement or other arrangement with any of our Named Executive Officers in the event of a change of control involving the Company, other than in respect of outstanding restricted stock units granted under the Plans. For restricted stock units granted under the Plans, upon a change of control all such restricted stock units shall only become vested if the acquiring or surviving corporation does not assume such restricted stock units. If the acquiring company assumes such restricted stock units and the employment of a holder of any such assumed restricted stock unit, including a Named Executive Officer, is terminated without

44

cause within 24 months of such change of control, then all such assumed restricted stock units of such holder shall become immediately vested. Notwithstanding the foregoing, the Plans provide that the applicable award agreement shall govern the treatment of an award upon a change of control, which may differ from the foregoing, and any such provision for a change of control shall be in a manner consistent with the provisions of Section 409A of the Code.

Based upon a price per share of $40.37 (the closing sales price of a share of our Common Stock on December 31, 2025, the last business day of 2025 as quoted by the NYSE) and the number of restricted stock units held by our Named Executive Officers that were unvested as of December 31, 2025 (information concerning such unvested restricted stock units is provided in the Outstanding Equity Awards at Fiscal Year-End Table), we estimate the value related to the immediate vesting of these unvested restricted stock units held by each of our Named Executive Officers upon a change of control involving the Company (assuming the acquiring or surviving corporation does not assume the outstanding restricted stock units under the Plans) to be as follows:

CEO Pay Ratio

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing the ratio of the median of the annual total compensation of all of our employees to the annual total compensation of Mr. Adam J. Greenlee, our CEO and President. For 2025, our last completed fiscal year:

Based on this information, for 2025 the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all of our employees was estimated to be 262 to 1.

The following calculation, which is not required under the SEC’s rules and is not a substitute for the presentation of the ratio above that is required under the SEC’s rules, provides the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all of our employees using the total compensation of our CEO in 2025 that reflects the Compensation Committee’s view on the compensation attributable to Supplemental Stock Awards, which spreads such compensation attributable to such Supplemental Stock Awards evenly over the entire vesting period of such Supplemental Stock Awards instead of all in the year of grant. For further information on such Supplemental Stock Awards, you should read the section in this Proxy Statement titled “Executive Compensation—Total Compensation with Supplemental Stock Awards Allocated Over Vesting Period.” For 2025, the annual total compensation of our CEO, reflecting the compensation attributable to the Supplemental Stock Awards granted to him spread evenly over the entire vesting period of such Supplemental Stock Awards, was $10,843,983, and the ratio of such annual total compensation of our CEO to the median of the annual total compensation of all of our employees was estimated to be 232 to 1.

45

Our previous median-compensated employee for 2023 and 2024 in our proxy statements for our annual meetings of stockholders in 2024 and 2025 was identified on December 31, 2023. For 2025, we determined to identify a new median-compensated employee for our proxy statement for our annual meeting of stockholders in 2026. The annual total compensation for 2025 of our new median-compensated employee was lower than the annual total compensation for 2024 of our previous median-compensated employee as a result of (i) the closing of several plants in the United States during 2024 and 2025 in connection with a cost reduction initiative announced in late 2023 and (ii) the inclusion for 2025 of employees of Weener Packaging which we acquired in late 2024, most of whom are located outside of the United States and many of whom earn lower compensation as compared to our employees in the United States.

We applied the following methodology and made the following material assumptions, adjustments and estimates, all as permitted by the SEC rules, to identify our median-compensated employee:

Once we identified our median-compensated employee, we calculated such employee’s annual total compensation for 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, which are the same requirements used to calculate the annual total compensation of our CEO as reported in the Summary Compensation Table included elsewhere in this Proxy Statement.

The CEO pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and based on the methodology, assumptions, adjustments and estimates described above, which were chosen from a wide range of permissible methodologies, assumptions, adjustments and estimates. As a result, the CEO pay ratios reported by other companies, which may have employed other permitted methodologies, assumptions, adjustments and estimates and which may have a significantly different work force structure than ours, are likely not comparable to our CEO pay ratio.

PROPOSAL 2: APPROVAL OF THE FIRST AMENDMENT TO THE SILGAN HOLDINGS INC. SECOND AMENDED AND RESTATED 2004 STOCK INCENTIVE PLAN

You are being asked to approve the First Amendment, or the Amendment, to the Silgan Holdings Inc. Second Amended and Restated 2004 Stock Incentive Plan, or, for purposes of this proposal only, the Plan. The purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by (i) encouraging officers and other key employees and non-employee directors of the Company to focus on critical long-range objectives, (ii) encouraging the attraction and retention of officers and other key employees and non-employee directors with exceptional qualifications and (iii) linking officers and other key employees and non-employee directors of the Company directly to stockholder interests through increased stock ownership. The Plan provides for awards of stock options, stock appreciation rights, restricted stock, restricted stock units and performance awards. The Plan was approved and adopted by our Board of Directors on March 23, 2023 and approved by our stockholders on May 30, 2023.

Summary of the Amendment

The Amendment was approved and adopted by our Board of Directors, effective as of April 2, 2026, subject to approval of the Amendment by our stockholders at the Meeting. As discussed below, the Amendment will effect the following changes to the Plan (which are in addition to certain non-substantive clarifications and improvements):

Voting Required

Stockholder approval of the Amendment requires the favorable vote of a majority of the votes cast at the Meeting. If stockholders do not approve the Amendment, we will likely be able to continue granting equity awards to our officers, key employees and directors under the Plan in 2026, but may be unable to grant equity awards thereafter.

Description of the Plan

The principal features of the Plan, as proposed to be amended pursuant to the Amendment, are summarized below. The following summary does not purport to be a complete description of all of the provisions of the Plan. It is qualified in its entirety by reference to the complete text of the Amendment, as set forth in Appendix A to this Proxy Statement, as well as the terms of the Plan, which can be found as Exhibit 10.21 to our Annual Report on Form 10-K for the year ended December 31, 2025.

Shares Available Under the Plan

The Plan, as of March 23, 2023, provided for the issuance of up to 3,410,184 shares of our Common Stock pursuant to awards under the Plan. If the Amendment is approved by our stockholders at the Meeting, the Plan will provide for the issuance of up to 4,410,758 shares of our Common Stock, which will have the effect of increasing the number of shares available for grant under the Plan by 4,000,000.

53

If the Amendment is approved by our stockholders at the Meeting, we anticipate that we will have sufficient shares of Common Stock reserved to make equity grants to participants under the Plan for the foreseeable future based on our past practices. The closing sales price of our Common Stock was $39.48 per share on April 2, 2026, as quoted by the NYSE.

As of the Record Date, the Company’s “equity overhang,” or the percentage of outstanding shares of our Common Stock represented by all equity awards granted under the Plan plus all shares available for future grants under the Plan, was 1.81%. If the Amendment is approved by our stockholders at the Meeting, the equity overhang represented by all equity awards granted and available for future grant under the Plan would have been 3.60% as of the Record Date. The Company’s equity overhang has ranged between 2.03% and 3.03% from 2021 through 2025 and has averaged 2.47% over such period. Equity overhang is calculated as all shares issuable upon vesting of outstanding restricted stock units plus all shares available for future grants of restricted stock units under all plans, divided by the sum of (a) the number of shares of our Common Stock outstanding plus (b) the number of shares in the numerator. The Company does not currently have any outstanding stock options or any equity plans other than the Plan. Our equity overhang has been calculated on the assumption that all shares available for future grant are in the form of restricted stock units (whether time-vested or containing performance conditions), as the Compensation Committee has issued only restricted stock units under the Plan (although the Compensation Committee may issue other types of awards under the Plan as described below).

Another measurement that may be considered meaningful by some stockholders in connection with a proposal to increase the number of shares available under an equity plan is the “burn rate.” The burn rate is calculated as restricted stock units granted in a fiscal year, divided by the number of shares of our Common Stock outstanding at the end of that fiscal year. Our burn rate for 2025 was 0.77%, for 2024 was 0.49%, for 2023 was 0.28% and for the last five years has averaged 0.45%. Grants of restricted stock units to newly hired officers of the Company and its subsidiaries in 2025 and in connection with promotions in 2025 resulted in a higher burn rate in 2025 as compared to previous years. We anticipate our average burn rate under the Plan will be approximately 0.60% over the next five years, calculated assuming that the Compensation Committee continues to issue only restricted stock units under the Plan (although the Compensation Committee may issue other types of awards under the Plan as described below).

Each award of stock options or stock appreciation rights under the Plan, if any, would reduce the number of shares of our Common Stock available for future issuance under the Plan by the number of shares of our Common Stock subject to the award. For this purpose, if a stock option and a stock appreciation right are awarded in tandem so that the exercise of one results in the cancelation of the other, then the stock option and the stock appreciation right are deemed to relate to the same share of our Common Stock. In contrast, each award of restricted shares or restricted stock units under the Plan reduces the number of shares of our Common Stock available for future issuance under the Plan by two shares for every one restricted share or restricted stock unit awarded.

Shares of our Common Stock subject to awards that are forfeited under the Plan or a prior plan will be added back to the share reserve under the Plan. If the Company assumes or converts awards made under a plan of another entity that the Company acquires or merges with, those assumed or converted awards do not reduce the number of shares of our Common Stock available for future issuance under the Plan.

Appropriate adjustments may be made to the maximum number of shares of our Common Stock available for issuance under the Plan in the event of a stock split, stock dividend, reclassification or similar event. Such events may also result in adjustments to the number of shares of our Common Stock subject to awards previously granted under the Plan.

54

Administration

The Compensation Committee is responsible for administering the Plan. The Compensation Committee selects or approves award recipients, sets the terms and conditions of awards, makes adjustments to outstanding awards and to the share reserve as permitted by the Plan, interprets the Plan and prescribes rules for administering the Plan. While the Compensation Committee is permitted to amend outstanding awards, it is not permitted to reduce the exercise price of any outstanding stock option or stock appreciation right without obtaining approval of our stockholders.

Eligibility and Limits on Awards

The Compensation Committee retains the sole discretion to select or approve the selection of employees to receive awards under the Plan. Each of the approximately fifty officers and other key employees of the Company and its subsidiaries is potentially eligible to receive awards under the Plan. Currently, each of the non-employee directors of the Company will receive restricted shares or restricted stock units annually under and in accordance with the Plan. We currently have eight non-employee directors, and, if all of the nominees for Class II Director of the Company are elected by our stockholders at the Meeting, we will continue to have eight non-employee directors.

No more than 1,800,000 shares of our Common Stock in the aggregate may be granted to any employee in any period of 36 consecutive months pursuant to stock options and stock appreciation rights. In addition, if the Amendment is approved by our stockholders at the Meeting, no more than 1,200,000 shares of our Common Stock in the aggregate may be awarded to any one employee during any period of 36 consecutive months pursuant to awards of restricted shares or restricted stock units or otherwise pursuant to performance awards. Each of the foregoing maximum aggregate number of shares of our Common Stock set forth in this paragraph is subject to adjustment in the event of a stock split, stock dividend, reclassification or similar event.

The limits described above are not intended to indicate that all of these awards are or will be made, or that awards are or will be made up to these limits.

5% Pool of Awards

If the Amendment is approved by our stockholders at the Meeting, a pool of 5% of the total shares available to be granted under the Plan will be available to grant to participants under the Plan (other than to the Company’s Chief Executive Officer) without any minimum vesting, exercisability or performance period requirements. Any shares granted under the Plan in connection with awards that are assumed, converted or substituted as a result of the acquisition of another business, corporation or other entity by the Company or a combination of the Company with another business shall not apply against this 5% pool of shares. The number of shares available for awards for this 5% pool of shares shall be determined in the same manner as described above under “Shares Available Under the Plan.”

Types of Awards

Stock Options and Stock Appreciation Rights. Stock options give the holder the right to purchase shares of our Common Stock at a specified exercise price. Stock appreciation rights give the holder the right to receive, without any payment on the holder’s part, the excess of the fair market value of the shares of our Common Stock subject to the right at the time of exercise over a specified exercise price. All stock options granted under the Plan will be nonqualified stock options for federal income tax purposes.

The exercise price of a stock option or stock appreciation right may not be less than the fair market value of the shares of our Common Stock subject to the award on the date of grant. Awards to employees become fully vested over a period no shorter than 12 months (except as set forth above under “5% Pool of Awards”) and have a term no longer than seven years. The ability to exercise vested stock options and stock appreciation rights after termination of employment is limited.

55

Stock appreciation rights may be granted alone or in tandem with a grant of stock options. When granted in tandem, the exercise of a stock option for a specified number of shares cancels the stock appreciation right for the same number of shares, and exercise of the stock appreciation right has a similar impact on the shares available under the stock option. Stock appreciation rights may be payable in cash or in shares of our Common Stock, or a combination of both, in each case having a value equal to the excess of the fair market value of the shares of our Common Stock subject to the stock appreciation right at the time of exercise over the exercise price. The Compensation Committee may permit or require such payments to be made in a lump sum or in installments.

Restricted Shares and Restricted Stock Units. Restricted shares are actual shares of our Common Stock that are subject to vesting requirements and transfer restrictions. A restricted stock unit represents the right to receive one share of our Common Stock at a future date. Restricted stock units are subject to vesting requirements and may permit the holder to defer receipt of actual shares of our Common Stock to a date subsequent to the date the restricted stock units vest. Awards of restricted shares and restricted stock units generally do not require the recipient to pay for the shares of our Common Stock, but the Compensation Committee may require payment for restricted shares.

Restricted shares and restricted stock units awarded to employees may become vested over a period no shorter than three years from the date of grant, except as set forth above under “5% Pool of Awards” and except that awards to new employees may vest more quickly but over a period of at least one year. Awards of restricted shares and restricted stock units to non-employee directors may vest over a period no shorter than the approximately 12 month period beginning on the first business day following each annual meeting of stockholders of the Company and ending on the date of the next annual meeting of stockholders of the Company. Holders of restricted shares have the same voting and dividend rights as other holders of shares of our Common Stock. While holders of restricted stock units have no voting and dividend rights, as they do not hold actual shares of our Common Stock, awards of restricted stock units may provide for dividend equivalents.

Performance Awards. A performance award under the Plan is an award of restricted shares or restricted stock units where the grant of the award, or the vesting of the award, is subject to the attainment of specified performance goals. The Compensation Committee sets performance goals over periods that it selects in advance, which cannot be shorter than 12 months (except as set forth above under “5% Pool of Awards”), and after the end of each period the Compensation Committee confirms the extent to which those goals are attained. A performance award will vest over such period as determined by the Compensation Committee in its discretion.

The performance goals are based on the attainment by the Company, or by one or more business units or subsidiaries of the Company, of specified levels of performance criteria, which may include one or more of the following:

56

The Compensation Committee determines whether to measure performance under these criteria in absolute terms or in comparison to the performance of other corporations. In applying these criteria to a particular period, the Compensation Committee may, in its discretion, exclude the impact of the following: unusual or infrequently occurring charges (including, without limitation, the impact from any foreign currency devaluations and acquisition termination fees (net of related costs)); the amount of all charges and expenses incurred or income earned in connection with any refinancing, restructuring, rationalization, recapitalization or reorganization; the cumulative effect of accounting changes; discontinued operations; and any business units, divisions, subsidiaries or other entities sold or acquired. In addition, the Compensation Committee may determine after the commencement of an applicable performance period to exclude other items, each determined in accordance with generally accepted accounting principles in the United States as applicable. Notwithstanding the attainment of the performance goals for a particular period, the Compensation Committee may decrease the amount payable under any individual’s performance award, as long as that action does not increase the payment to any other holder of a performance award.

Director Awards. Pursuant to the Plan, as of the first business day following the day of each annual meeting of our stockholders (including the Meeting), each non-employee director is awarded either restricted shares of our Common Stock or restricted stock units related to shares of our Common Stock, with an aggregate fair market value of $125,000 as of the date of grant, rounded down to the nearest number of whole shares or whole stock units. Awards to non-employee directors will vest over a period no shorter than the approximately 12 month period beginning on the first business day following each annual meeting of stockholders of the Company and ending on the date of the next annual meeting of stockholders of the Company.

Deferral

The Compensation Committee may permit a participant to defer receipt of any cash that otherwise would be paid as a result of the exercise of a stock appreciation right or of any Common Stock that otherwise would be delivered as restricted shares or as a result of the exercise of a stock option or stock appreciation right or the settlement of restricted stock units. The Compensation Committee may also prescribe rules for the treatment of deferred amounts in the event of a participant’s termination of service. A deferral may be credited with dividend equivalents, interest or other forms of investment return, as determined by the Compensation Committee. Any dividend equivalents provided on the deferral amounts are paid immediately to the participant. A participant does not have voting rights with respect to deferred shares of Common Stock until the shares are distributed to the participant.

Change in Control

Equity awards are subject to “double trigger” change in control vesting, which means that in the event of a change in control of the Company, as defined in the Plan, all outstanding stock options and stock appreciation rights will become vested and exercisable, unless the acquiring or surviving corporation assumes those awards or

57

substitutes its own stock for the shares underlying the awards. Also, a change in control will result in the waiver of all restrictions with respect to outstanding restricted shares and restricted stock units and any performance awards that have been earned but remain unvested will immediately become vested, in each case unless the acquiring or surviving corporation assumes the awards or substitutes its own stock for the shares underlying the awards. A participant’s assumed or substituted stock options, stock appreciation rights, restricted shares, restricted stock units and performance awards will immediately vest if the participant’s service with the Company or the acquiring or surviving corporation is terminated involuntarily without cause within 24 months after the change in control.

Unless an award provides otherwise, any amounts credited to a deferred compensation account will continue to be deferred following a change in control if our Common Stock continues to be publicly traded. If our Common Stock is not publicly traded following the change in control, the full value of the deferred amounts will be settled in cash and immediately distributed to the participant.

Transfer

Awards may not be transferred by a participant other than by will or the laws of descent and distribution, except that restricted shares may be freely transferred after the restrictions lapse or are satisfied and unrestricted shares of Common Stock are delivered.

Amendment and Termination

The Plan may be amended or terminated by the Board of Directors at any time without stockholder approval, except that any material revision to the terms of the Plan requires stockholder approval before it can be effective. A revision is “material” for this purpose if, among other changes, it materially increases the number of shares of our Common Stock that may be issued under the Plan (other than an increase pursuant to an adjustment for stock splits, stock dividends or other events permitting adjustments under the Plan), changes the types of awards under the Plan, materially expands the class of persons eligible to receive awards under the Plan, materially extends the term of the Plan, materially decreases the exercise price at which stock options or stock appreciation rights may be granted in the future, reduces the exercise price of outstanding stock options or stock appreciation rights or results in the replacement of outstanding stock options or stock appreciation rights with awards that have a lower exercise price. Accordingly, the Amendment is “material” under the terms of the Plan. No amendment of the Plan can adversely affect the rights of any holder of an outstanding award without the holder’s written consent.

If stockholders of the Company approve the Amendment at the Meeting, the Plan will automatically terminate on June 30, 2031, if not terminated earlier by the Board of Directors. If stockholders of the Company do not approve the Amendment at the Meeting, the Plan will automatically terminate on March 31, 2029, if not terminated earlier by the Board of Directors. No awards may be granted under the Plan after it is terminated, but any previously granted awards will remain in effect until they expire in accordance with the terms of the Plan and the applicable award agreements.

Other

If our stockholders approve the Amendment at the Meeting, the Plan will include a provision stating that awards (including applicable dividend equivalents) will be subject to the Clawback Policy adopted by the Company. Since the Clawback Policy was adopted by the Company, award agreements for awards granted under the Plan have included such a provision. Information on the Clawback Policy adopted by the Company is set forth in the section of this Proxy Statement titled “Executive Compensation—Compensation Discussion and Analysis—Clawback Policy.”

58

New Plan Benefits

If the Amendment is approved by our stockholders at the Meeting, the awards that will be granted in the future under the Plan are not currently determinable, other than awards to non-employee directors. Because awards under the Plan will depend on the market value of our Common Stock in the future and decisions of the Compensation Committee, it is not possible to determine the benefits that will be received by officers and other key employees of the Company and its subsidiaries under the Plan if the Amendment is approved by our stockholders at the Meeting. For information on how the Compensation Committee determines to grant awards under the Plan to officers and other key employees of the Company and its subsidiaries, you should read the section of this Proxy Statement titled “Executive Compensation—Compensation Discussion and Analysis—Equity Based Compensation.” For information on awards made under the Plan to the Named Executive Officers in 2025, you should read the section in this Proxy Statement titled “Executive Compensation—Plan Based Awards.” The following table sets forth information with respect to awards of restricted shares or restricted stock units to be granted each year to non-employee directors pursuant to and under the Plan, if the Amendment is approved by our stockholders at the Meeting.

Federal Income Tax Consequences

The following is a brief summary of the current principal United States federal income tax consequences of the grant, exercise and disposition of awards under the Plan. This summary is not intended to be exhaustive and, among other things, does not describe state, local or foreign tax consequences.

Stock Options and Stock Appreciation Rights

A participant does not recognize any income at the time a stock option or stock appreciation right is granted, nor is the Company entitled to a deduction at that time. When a stock option is exercised, the holder recognizes ordinary income in an amount equal to the excess of the fair market value of shares of Common Stock received as of the date of exercise over the exercise price. When a stock appreciation right is exercised, the holder recognizes ordinary income in an amount equal to the cash received or, if the right is paid in shares of Common Stock, the fair market value of our Common Stock recognized as received as of the date of exercise. Payroll taxes are required to be withheld from the holder on the amount of ordinary income recognized by the holder. The Company is entitled to a tax deduction with respect to a stock option or stock appreciation right at the same time and generally in the same amount as the holder recognizes income.

Restricted Shares

A participant does not recognize any income at the time restricted shares of our Common Stock are granted, nor is the Company entitled to a deduction at that time. In the year in which restrictions on restricted shares lapse, the participant recognizes ordinary income in an amount equal to the excess of the fair market value of the shares on the date of vesting over the amount, if any, that the participant paid for the shares. A participant may, however, elect within 30 days after receiving restricted shares to recognize ordinary income in the year of receipt

59

instead of the year of vesting. If an election is made, the amount of income recognized by the participant is equal to the excess of the fair market value of the shares on the date of receipt over the amount, if any, the participant paid for the shares. Payroll taxes are required to be withheld on the income recognized by the participant. The Company will be entitled to a tax deduction at the same time and generally in the same amount as the participant recognizes income.

Restricted Stock Units

A participant does not recognize any income at the time a restricted stock unit is granted, nor is the Company entitled to a deduction at that time. When payment on a restricted stock unit is made, the participant recognizes ordinary income in an amount equal to the fair market value of the shares of Common Stock received. Payroll taxes are required to be withheld on the income recognized by the participant (or, if the award is subject to a vesting schedule, on the vesting date). The Company is entitled to a tax deduction at the same time and generally in the same amount as the participant recognizes income.

Performance Awards

A participant does not recognize any income at the time a performance award is granted, nor is the Company entitled to a deduction at that time. To the extent a performance award is paid in restricted shares, a participant recognizes compensation income in the year in which the award vests and in the amount of the fair market value of the shares of Common Stock as of the vesting date. To the extent a performance award is paid in restricted stock units, a participant recognizes compensation in the year of payment in the amount of the fair market value of the shares of Common Stock as of the payment date. Payroll taxes are required to be withheld on performance awards on the vesting date (or, if the award is not subject to a vesting schedule, on the payment date). The Company is entitled to a tax deduction at the same time and generally in the same amount as the participant recognizes income.

Code Section 409A

Awards that result in the deferral of compensation are subject to ordinary income tax and penalties in the year of vesting unless they satisfy the requirements of Section 409A of the Code. It is the intent of the Company to structure awards and administer the Plan in a manner that complies with the requirements of Section 409A.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE FIRST AMENDMENT TO THE SILGAN HOLDINGS INC. SECOND AMENDED AND RESTATED 2004 STOCK INCENTIVE PLAN.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee is governed by a written charter approved by the Company’s Board of Directors. In accordance with the written charter of the Audit Committee, the applicable listing standards of the NYSE and the applicable rules of the SEC, all members of the Audit Committee are independent. The Audit Committee held eight meetings during 2025.

The Audit Committee provides assistance to the Board of Directors of the Company in fulfilling its oversight responsibility relating to the Company’s consolidated financial statements and financial reporting process, systems of internal accounting and financial controls, internal audit activities and compliance with legal and regulatory requirements relating to accounting and financial reporting matters and the annual independent audits of the Company’s consolidated financial statements and the effectiveness of the Company’s internal control over financial reporting. Management of the Company is responsible for the consolidated financial statements and reporting process of the Company, including maintaining effective internal control over financial reporting and assessing the effectiveness of the Company’s internal control over financial reporting. Ernst & Young LLP, the independent registered public accounting firm of the Company, is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States), or the PCAOB, and for issuing a report thereon. The independent registered public accounting firm is also responsible for auditing the effectiveness of the Company’s internal control over financial reporting. The Audit Committee’s responsibility is to oversee these audits and the financial reporting process of the Company.

In fulfilling its oversight responsibilities, the Audit Committee discussed with management, the Company’s internal auditors and the Company’s independent registered public accounting firm the overall scope and plans for the Company’s audits. The Audit Committee met with the Company’s internal auditors and independent registered public accounting firm, with and without management present, to discuss the Company’s audits, the Company’s consolidated financial statements and the effectiveness of the Company’s internal control over financial reporting. The Audit Committee also reviewed and discussed with management and the Company’s independent registered public accounting firm the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Additionally, the Audit Committee reviewed with management its report on its assessment of the effectiveness of the Company’s internal control over financial reporting and the independent registered public accounting firm’s report on the effectiveness of the Company’s internal control over financial reporting.

The Audit Committee has received the written disclosures and the letter from the Company’s independent registered public accounting firm required by the applicable requirements of the PCAOB regarding such firm’s communications with the Audit Committee concerning independence, and has discussed with the Company’s independent registered public accounting firm such firm’s independence. The Audit Committee has also considered the compatibility of nonaudit services with such firm’s independence. Additionally, in assessing such firm’s independence, the Audit Committee reviewed the amount of fees paid to the Company’s independent registered public accounting firm for audit and nonaudit services.

The Audit Committee has also discussed with the Company’s independent registered public accounting firm the matters required to be discussed by Auditing Standard 1301, as adopted by the PCAOB in Rule 3200T.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors of the Company that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the SEC.

The Audit Committee is also directly responsible for the appointment, compensation, retention and oversight of the work of the independent registered public accounting firm of the Company. Accordingly, the Audit Committee has approved, subject to stockholder ratification, the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026.

62

In addition, the Audit Committee reviews and discusses with management and the Company’s independent registered public accounting firm the Company’s Quarterly Reports on Form 10-Q and its earnings press releases.

The Audit Committee has adopted a formal policy, consistent with its written charter, that requires its approval in advance for any audit, audit-related, tax and other services to be performed by the Company’s independent registered public accounting firm. Pursuant to its formal policy, the Audit Committee approved in advance all audit, audit-related, tax and other services performed by the Company’s independent registered public accounting firm in 2025. This policy provides that the Audit Committee may delegate to any of its members the authority to approve in advance any audit and nonaudit services to be performed by the Company’s independent registered public accounting firm, and, in such case, requires such member to report any decisions to the Audit Committee at its next scheduled meeting.

PROPOSAL 3: RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Appointment of Independent Registered Public Accounting Firm

The Audit Committee of the Board of Directors of the Company has appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026. The Board of Directors of the Company is requesting ratification of this appointment by the stockholders of the Company. It should be noted however that, even if this appointment is ratified by the stockholders of the Company, the Audit Committee in its discretion may replace the Company’s independent registered public accounting firm and appoint a new independent registered public accounting firm for the Company at any time during the year if it determines that such a change would be in the best interests of the Company.

A representative of Ernst & Young LLP is expected to be present at the Meeting and to be available to respond to appropriate questions from those attending the Meeting, but is not otherwise expected to make a statement.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026.

PROPOSAL 4: ADVISORY VOTE TO APPROVE

COMPENSATION OF NAMED EXECUTIVE OFFICERS

At our annual meeting of stockholders in 2023, for the advisory vote on the frequency of future advisory votes on the compensation of the Company’s Named Executive Officers, a frequency of every year received a majority of the votes cast at such meeting. In light of this result and other factors considered by the Board of Directors of the Company, the Board of Directors of the Company decided that the Company will hold an advisory vote on the compensation of its Named Executive Officers each year at its annual meeting of stockholders until the next required advisory vote on the frequency of the same, which is no later than the Company’s annual meeting of stockholders in 2029. Accordingly, pursuant to Section 14A of the Exchange Act, we are including in this Proxy Statement an advisory vote on the compensation of our Named Executive Officers as described in this Proxy Statement (commonly referred to as “Say-on-Pay”).

You should read the section of this Proxy Statement entitled “Executive Compensation” for a description of the compensation provided to our Named Executive Officers. The Company’s executive compensation program provides base salaries and annual cash incentive bonuses that enable the Company to attract and retain such executives and provide fair compensation to them taking into account responsibilities and relevant employment markets. The Company’s executive compensation program also provides equity-based compensation consisting primarily of performance awards of restricted stock units, which the Company believes fosters more balanced risk taking because restricted stock units are more closely linked to ownership of stock than other equity-based compensation. In addition, the Company provides modest retirement and other benefits primarily for purposes of retention to its executives other than Mr. Greenlee. Mr. Greenlee is not provided with any retirement or other benefits, thereby allowing him to assist the Compensation Committee in an unbiased manner in its oversight and review of such benefits.

Overall, the Board of Directors believes the compensation program for our Named Executive Officers attracts and retains them by providing fair compensation, rewards them for achieving short-term business goals and long-term creation of stockholder value while at the same time not encouraging excessive risk taking, and aligns their interests with the interests of our stockholders. The Board of Directors believes the compensation program for our Named Executive Officers strikes the appropriate balance between utilizing responsible, measured compensation practices and effectively incentivizing our executives to focus on long-term value creation for stockholders. Additionally, the Board of Directors believes that total compensation, as shown in the Summary Compensation Table, for any Named Executive Officer should be considered over a longer period of time than one year as a result of the fact that equity based awards may be granted in an uneven manner in one year as compared to another year based on the practices of the Compensation Committee in granting equity based awards as described in the section of this Proxy Statement titled “Compensation Discussion and Analysis— Equity Based Compensation.” Accordingly, the Board of Directors strongly endorses the Company’s compensation for our Named Executive Officers and recommends that the stockholders of the Company vote in favor of the following resolution:

RESOLVED, that the compensation provided to the Company’s Named Executive Officers, as described in this Proxy Statement in the section entitled “Executive Compensation,” including the Compensation Discussion and Analysis, compensation tables and the accompanying narrative disclosures, is hereby approved, on an advisory basis, by the stockholders of the Company.

Because this vote is advisory, it will not be binding upon the Company, and neither the Board of Directors nor the Compensation Committee will be required to take any action as a result of this vote. The Compensation Committee will consider the outcome of this vote when reviewing compensation matters in the future.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS OF THE COMPANY.

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Exchange Act requires our directors and officers and persons holding more than ten percent of a registered class of our equity securities to file with the SEC initial reports of ownership, reports of changes in ownership and annual reports of ownership of Common Stock and other equity securities of the Company. Based solely upon a review of the copies of reports furnished to us and/or representations that no reports were required, we believe that all of our directors, officers and ten percent stockholders complied with all filing requirements under Section 16(a) of the Exchange Act in 2025.
