PACCAR (PCAR) 2026 proxy outlines director elections, pay and auditor vote

Rhea-AI Filing Summary

PACCAR Inc is asking stockholders to vote at its April 28, 2026 annual meeting on electing twelve directors for one-year terms, approving on an advisory basis executive compensation, and ratifying the company’s independent auditors. Stockholders of record as of March 3, 2026, when 526,262,965 common shares were outstanding, are entitled to vote in person or by proxy.

The proxy describes PACCAR’s 2025 performance, including net sales and revenues of $28.44 billion, net income of $2.38 billion, and total stockholder return of 8% for the year. The company highlights record year-end stockholders’ equity of $19.26 billion, cash provided by operations of $4.42 billion, PACCAR Parts revenue of $6.87 billion, and PACCAR Parts pre-tax income of $1.67 billion.

Executive pay is heavily performance-based, with about 68% of target compensation for named executive officers tied to incentives. Annual bonuses are driven mainly by net income, while long-term incentives depend on three-year net income growth, return on sales, return on capital and total shareholder return versus a defined peer group. In 2025, over 93% of shares voting supported the advisory “Say on Pay” resolution.

Vote Required and Method of Counting Votes

The presence at the Annual Meeting – in person or by duly authorized proxy – of a majority of all the stock issued and outstanding and having voting power shall constitute a quorum for the transaction of business. Abstentions are counted as shares present at the meeting.

Item 1: Election of Directors

In an uncontested director election, each director nominee shall be elected by the affirmative vote of the majority of the votes cast with respect to that director’s election at any meeting for the election of directors at which a quorum is present. A majority of votes cast means that the number of shares voted “for” a director’s election exceeds 50 percent of the number of votes cast with respect to that director’s election. Votes cast include votes “against,” but exclude “abstentions” and “broker nonvotes” with respect to that director’s election. Pursuant to the Company’s Bylaws, an incumbent director that is not elected by a majority vote will tender his or her resignation subject to acceptance by the Board. The Company’s Certificate of Incorporation does not provide for cumulative voting. Proxies signed, dated and returned unmarked will be voted FOR all of the nominees.

Please note that brokers and custodians may not vote on the election of directors in the absence of specific client instruction. Those who hold shares in such accounts are encouraged to provide voting instructions to the broker or custodian.

If any nominee is unable to act as director because of an unexpected occurrence, the proxy holders may vote the proxies for another person or the Board of Directors may reduce the number of directors to be elected.

Item 2: Advisory Resolution to Approve Executive Compensation (“Say on Pay”)

Proxies signed, dated and returned unmarked will be voted FOR Item 2.

To be approved, Item 2 must receive the affirmative vote of a majority of the shares present in person or by proxy and entitled to vote on this item at the Annual Meeting. Abstentions will have the effect of a vote against the item. Broker nonvotes will not affect the outcome of the vote.

Item 3: Advisory Vote on the Ratification of Independent Auditors

THE BOARD RECOMMENDS A VOTE FOR EACH OF THE NOMINEES.

BOARD GOVERNANCE

The Board of Directors has determined that the following persons served as independent directors in 2025 as defined by Nasdaq Rule 5605(a)(2): Pierre R. Breber, Dame Alison J. Carnwath, Kirk S. Hachigian, Brice A. Hill, Barbara B. Hulit, Roderick C. McGeary (retired 4/27/25), Cynthia A. Niekamp (retired 4/26/26), Luiz A. S. Pretti, Ganesh Ramaswamy, Mark A. Schulz and Gregory M. E. Spierkel (retired 4/27/25).

The Board of Directors maintains a corporate governance section on the Company’s website, which includes key information about its governance practices. The Company’s Corporate Governance Guidelines, Board Committee Charters, Code of Business Conduct and Code of Ethics for Senior Financial Officers are located at www.paccar.com/about-us/board-of-directors. The Corporate Governance Guidelines prohibit the Company’s directors and executive officers from hedging or pledging their ownership of PACCAR stock. Employees, other than executive officers, are generally permitted to engage in transactions designed to hedge or offset market risk. The Company has adopted insider trading policies and procedures governing the purchase and sale of the Company’s securities by directors, officers and employees that are reasonably designed to promote compliance with applicable insider trading laws, rules and regulations and Nasdaq listing standards. See Exhibit 19 of the Company’s Annual Report on Form 10-K for additional information.

The Company’s leadership structure includes an Executive Chairman, a Chief Executive Officer and an independent lead director who serves for a three-year term. M. A. Schulz currently serves as lead director and was reelected for 2026. This leadership structure, in which the roles of the Executive Chairman and Chief Executive Officer are separate, together with an experienced and engaged lead director and independent key committees, is appropriate for the Company because it effectively allocates authority, responsibility and oversight between management, the Executive Chairman and the independent members of the Board.

The Company has policies to ensure a strong and independent board. The Board regularly meets in executive session without management. The lead director presides over the executive sessions of the Board’s independent directors. Seventy-five percent of the Company’s twelve director nominees are independent as defined under Nasdaq rules.

Perquisites were less than the $10,000 reporting threshold.

(e)R. C. McGeary and G. M. E. Spierkel served as directors until their retirement from the Board of Directors on April 27, 2025.

Non-Employee Director Compensation Program

In addition to the cash compensation described in footnote (a) in the previous table, on the first business day of the year, each non-employee director receives $175,000 in restricted stock or RSUs under the RSDC Plan. The number of restricted shares or RSUs is determined by dividing $175,000 by the closing price of a share of Company stock on the first business day of the year and rounding up to the nearest whole share. Non-employee directors newly elected during the calendar year receive a prorated award to reflect the number of calendar quarters the director will serve in the year of election. RSUs are credited to the director’s deferred stock unit account. Restricted shares or RSUs vest three years after the date of grant or upon retirement, death or disability. Restricted shares receive dividends and voting rights and RSUs receive dividend equivalents (treated as if reinvested at the closing price of Company stock on the dividend date) and have no voting rights.

Non-employee directors may also elect to defer all or a part of their cash retainer and fees to an income account or to a stock unit account under the RSDC Plan. The income account accrues interest at a rate equal to the simple combined average of the monthly Aa Industrial Bond yield averages for the immediately preceding quarter and is compounded quarterly. The stock unit account is credited with the number of shares of Company common stock that could have been purchased at the closing price on the date the cash compensation is payable. Stock units receive dividend equivalents (as described above) and have no voting rights.

Deferred accounts are paid out at or after retirement or termination in accordance with the director’s election. The stock unit account is distributed in shares of the Company’s common stock. The deferred stock units held by non-employee directors are reflected in footnote (b) to the Stock Ownership Table on page 5.

The Company provides transportation or reimburses non-employee directors for travel and out-of-pocket expenses incurred in connection with their services. It also pays or reimburses directors for expenses incurred to participate in continuing education programs related to their service as a PACCAR director.

Stock Ownership Guidelines for Non-Employee Directors

All non-employee directors are expected to hold at least five times their annual cash retainer in Company stock and/or deferred stock units while serving as a director. Directors have five years from the date of appointment to attain this ownership threshold. All non-employee directors with five or more years of service have the required stockholding as of January 1, 2026.

POLICIES AND PROCEDURES FOR TRANSACTIONS WITH RELATED PERSONS

Under its charter, the Audit Committee of the Board of Directors is responsible for reviewing and approving related-person transactions as set forth in Item 404 of the Securities and Exchange Commission Regulation S-K. The Committee will consider whether such transactions are in the best interests of the Company and its stockholders. The Company has written procedures designed to bring such transactions to the attention of management. Management is responsible for presenting related-person transactions to the Audit Committee for review and approval.

Compensation Program Objectives and Structure

PACCAR’s compensation programs are directed by the Compensation Committee of the Board of Directors, composed exclusively of independent directors. The programs are designed to attract and retain high-quality executives, link incentives to the Company’s performance and align the interests of management with those of stockholders. These programs offer compensation that is competitive with companies that operate in the same industries globally. PACCAR’s goal is to achieve superior performance measured against its industry peers. The Company has achieved 87 consecutive years of net income, paid annual dividends every year since 1941 and delivered a total stockholder return of 8 percent in 2025. PACCAR’s average annual total return to stockholders has exceeded that of the S&P 500 Index over the last 5-, 10- and 20- year periods ended December 31, 2025. The compensation framework has these components:

Short-term performance compensation:

•Salary. The fixed amount of compensation for performing day-to-day responsibilities.

•Annual incentive cash compensation. Annual cash awards that focus on the attainment of Company profit targets and individual business unit goals.

Long-term performance compensation:

•An equity- and cash-based Long-Term Incentive Plan (“LTIP”) that focuses on long-term growth in stockholder value, including three-year performance versus industry peers as measured by net income change, return on sales, return on capital and total shareholder return. The equity-based compensation consists of stock options and restricted stock or RSUs.

The Committee believes that this combination of salary, cash incentives and equity-based compensation provides appropriate incentives for executives to deliver superior short- and long-term business performance and stockholder returns.

The Named Executive Officers and all U.S. salaried employees participate in the Company’s retirement programs. The Named Executive Officers also participate in the Company’s unfunded Supplemental Retirement Plan described on page 30, which provides a retirement benefit to those employees affected by the maximum benefit limitations permitted for qualified plans by the Internal Revenue Code and other qualified plan benefit limitations.

The Company does not provide any other significant perquisites or executive benefits to its Named Executive Officers.

Stockholder Approval for the Company’s Executive Compensation Programs (“Say on Pay”)

In 2025, stockholders voted on an advisory basis to approve the compensation of the Named Executive Officers with over 93 percent of the shares voting to approve the Company’s compensation practices. The Committee believes the stockholder vote affirms the Company’s conservative approach to executive compensation.

Executive Compensation Criteria

The Committee considers a number of important factors when reviewing and determining executive compensation, including job responsibilities, Company performance, business unit performance, individual performance and compensation for executives among peer organizations. The Committee also considers the opinion of the Chief Executive Officer when determining compensation for the executives that report to him.

Table of Contents

Industry Compensation Comparison Groups. The Committee periodically utilizes information from published compensation surveys as well as compensation data from Peer Companies to determine if compensation for the Chief Executive Officer and other executive officers is competitive with the market. The Committee believes that comparative compensation information should be used in its deliberations. It does not specify a “target” compensation level for any given executive but rather a range of target compensation. The Committee has discretion to determine the nature and extent to which it will use comparative compensation data.

Role of Compensation Consultants. The Committee typically retains a compensation consultant to assess the competitiveness of the Company’s compensation programs every two years. It did not employ a compensation consultant in 2025. The Committee adopted the current executive salary structure effective January 1, 2025.

Peer Companies. As part of its analysis of comparative data, the Committee includes compensation data from Peer Companies. In particular, the Company measures its financial performance against Peer Companies when evaluating achievement of the cash portion of the LTIP Company Performance Goal. The Committee reviews the composition of the Peer Companies annually to ensure the companies are appropriate for comparative purposes. The Peer Companies are listed below. The Peer Group Index is shown on page 42.

Company Name		FY 2025 Revenue (in $ billions)
PACCAR Inc				28.4
AGCO Corporation				10.1
Caterpillar Inc.				67.6
Cummins Inc.				33.7

Elements of Total Compensation

The Company’s executive compensation program is comprised of base salaries, annual incentive cash and long-term incentives consisting of cash, stock options and restricted stock/RSUs.

Compensation Element		Designed To Reward		Relationship To The Objectives
Base Salary		•Experience, knowledge of the industry, duties and scope of responsibility		•Provides a level of cash compensation to attract and retain talented executives to the Company who can continue to improve the Company’s overall performance
Short-Term Incentive    Compensation		•Success in achieving annual objectives		•Motivates executives to achieve specific Company-wide and business unit objectives •Provides competitive compensation to attract and retain talented executives
Long-Term Incentive    Compensation		•Continued excellence and attainment of objectives over time •Success in long-term growth and development		•Motivates executives to achieve long-term business unit and Company-wide objectives •Aligns the executives’ interests with long-term stockholder interests in order to increase overall stockholder value •Provides competitive compensation to attract and retain talented executives

Compensation Mix. The Company’s executive compensation program structure includes a balance of salary and annual and long-term incentives, including Company equity. For 2025, the Committee approved target allocations as displayed below for R. P. Feight, the Company’s Chief Executive Officer, and the other Named Executive Officers. The Company believes these allocations promote its objectives of profitable growth and superior long-term results, which benefit stockholders.

Base Salary. Base salary provides a level of compensation that is competitive with industry Peer Companies to attract and retain high-caliber executives. The midpoints of the base salary ranges are set at approximately the market median of the 2024 Mercer report with the minimum salary at 70 percent of the midpoint and the maximum salary at 130 percent of the midpoint. An executive officer’s actual salary relative to this salary range reflects his or her responsibility, experience, tenure with the Company and individual performance.

Table of Contents

The Committee reviews base salaries every 12 to 24 months and may or may not approve changes. Consistent with this practice, the Committee reviewed the salary of each Named Executive Officer in 2025. The Committee considered performance, the addition of new responsibilities and the midpoint of the base salary range. The Chief Executive Officer suggested salary revisions for the other Named Executive Officers. The Committee approved salary percentage increases in 2025 as follows: R. P. Feight, 4.5 percent; B. J. Poplawski, 13.3 percent; K. D. Baney, 9.1 percent; C. M. Dozier, 4.9 percent; D. C. Siver, 4.9 percent. The Committee believes these increases align the Named Executive Officers with the salaries of the median of the industry peer group reflecting current market trends and the responsibilities of the Named Executive Officers. The Committee believes that the base salary of each Named Executive Officer is appropriate based on scope of responsibility, experience, tenure with the Company, individual performance and competitive pay practices.

Annual Incentive Cash Compensation (“IC”). This program provides yearly cash incentives for the Named Executive Officers to achieve annual Company profit and business unit goals. Subject to the funding maximums established by the Committee that are described below under the heading “IC Funding Limit,” the Committee sets annual performance goals and a threshold, target and maximum award for each Named Executive Officer, expressed as a percentage of base salary. 2025 awards are measured on a sliding scale as follows:

% of Goal Achieved		<70%		70%		85%		100%		115%		130%		140% and above
% of Target Paid		0%		40%		70%		100%		130%		160%		200%

A hallmark of the annual cash incentive program has been a consistent and rigorous focus on achieving the Company’s annual net income goal. The Committee has chosen net income, not EBITDA or operating profit, as the chief financial metric for this program because it is the primary indicator of corporate performance to stockholders. When setting incentive compensation goals for the Named Executive Officers, the Committee believes that corporate performance is an appropriate measure of individual performance. Accordingly, the majority of the 2025 annual incentive compensation for the Chief Executive Officer and a substantial portion of the annual incentive compensation for each of the Named Executive Officers is based upon Company net income performance. The net income goal is proposed by Company management and approved by the Board and the Committee before or within the first 90 days of each year. The target level represents an amount of net income that the Committee determines is attainable with excellent performance under expected economic conditions. The remaining goals for the Chief Executive Officer and the other Named Executive Officers are based upon individual business unit or leadership criteria determined by the Committee for the Chief Executive Officer and by the Chief Executive Officer for the other Named Executive Officers. The Committee assesses annual goal achievement and approves awards for the Named Executive Officers.

For 2025, the Company’s IC net income target was $3.70 billion with a minimum threshold of $2.80 billion and a maximum threshold of $4.90 billion. The Committee approved the Company’s adjusted income of $2.85 billion, which excluded the $264.5 million after-tax charge related to civil litigation in Europe as well as the negative financial impact of direct tariffs. The Committee approved an overall payment for R. P. Feight of 62.7 percent of target, based on 71.8 percent achievement of the Company profit goal and 110 percent for his leadership in achieving the Company’s strategic initiatives in his role as Chief Executive Officer. The Committee approved an overall payment for B. J. Poplawski of 71.4 percent of target, including 71.8 percent achievement of the Company profit goal and 95 percent achievement for his leadership of Company growth initiatives. The Committee approved an overall payment for K. D. Baney of 66.6 percent of target, including 72 percent achievement of the business unit profit goals and 110 percent for his leadership of Company growth initiatives. The Committee approved an overall payment for C. M. Dozier of 70.6 percent of target, including 88.7 percent achievement of the business unit profit goals and 100 percent achievement for his leadership of Company growth initiatives. The Committee approved an overall payment for D. C. Siver of 62.5 percent of target, including 71.7 percent achievement of the business unit profit goals and 86.7 percent achievement for his leadership of Company initiatives. The Committee exercised discretion to reduce each Named Executive Officer’s maximum funding amount described below under the heading “IC Funding Limit” in determining payout as described above.

IC Funding Limit. IC awards for the Named Executive Officers are subject to the terms of the Senior Executive Yearly Incentive Compensation Plan (the “IC Plan”) approved by the stockholders. The maximum amount that may be paid to any eligible participant in any year under the IC Plan is $4,500,000. Pursuant to the IC Plan, the Committee established a yearly funding plan limit for 2025 IC awards equal to a percentage of the Company’s net income (the “Annual Pool”) and assigned a percentage of the Annual Pool to each Named Executive Officer. The 2025 funding limit equaled three percent of the Company’s net income and the corresponding maximum share of such pool for the current Chief Executive Officer and the next four most highly compensated executive officers was 43.3 percent, 22.5 percent, 12 percent, 12 percent and 10.2 percent, respectively. The Committee, in its sole discretion, may reduce or eliminate (but not increase) any award otherwise payable to the Named Executive Officers under each officer’s funding maximum based on the achievement of the IC Plan goals, an assessment of individual performance and other factors within the discretion of the Committee. The Committee exercised such discretion in determining the IC awards for 2025 performance.

Long-Term Incentive Compensation (“LTIP”). The Company’s long-term incentive program is based on a multi-year performance period and provides annual grants of stock options and cash incentive awards. The program also includes restricted stock/RSUs, which are awarded to certain executives based on the attainment of an annual performance goal and vest over three years. The LTIP aligns the interests of executives with those of stockholders to focus on long-term growth in stockholder value. The 2025 target for each element of the long-term compensation program for each Named Executive Officer is calculated as a percentage of base salary as indicated in the table below:

Name		Long-Term Cash					Stock Options					Restricted Stock/RSUs
R. P. Feight			270	%				600	%				270	%
H. C. Schippers (retired 6/2/25)			110	%				400	%				120	%
B. J. Poplawski			80	%				250	%				80	%
K. D. Baney			100	%				380	%				110	%

Long-term incentive compensation cash award. This program focuses on long-term growth in stockholder value by providing an incentive for superior Company performance that is measured against Peer Companies’ performance over a three-year period. Company performance is measured by the three-year change in net income, return on sales, return on capital and total shareholder return (weighted equally) as compared to the Peer Companies (“Company Performance Goal”). Named Executive Officers and all executive officers are eligible for a long-term incentive cash award based upon the three-year Company Performance Goal approved by the Committee with a new performance period beginning every calendar year.

Subject to the funding maximums established by the Committee that are described below under the heading “LTIP Funding Limit,” the Named Executive Officers’ goals for the 2025-2027 cycle are the following:

Name		Financial Performance and Individual Performance Measures for LTIP 2025-2027 Cycle		Performance Measure as a % of Target
R. P. Feight		Company Performance Goal		75
		Business Leadership		25
H. C. Schippers (retired 6/2/25)		Company Performance Goal		50
		Business Unit Profit		30
		Business Leadership		20
B. J. Poplawski		Company Performance Goal		40
		Company Profit Goal		30
		Business Leadership		30
K. D. Baney		Company Performance Goal		50
		Business Unit Profit		25
		Business Leadership		25
C. M. Dozier (retired 4/1/26)		Company Performance Goal		50
		Business Unit Profit		25
		Business Leadership		25
D. C. Siver (retired 1/7/26)		Company Performance Goal		50
		Business Unit Profit		25
		Business Leadership		25

The Committee believes that the three-year change in net income, return on sales, return on capital and total shareholder return are excellent indicators of the Company’s performance against the Peer Companies. The target amount will be earned if the Company’s financial performance ranks above at least half of the Peer Companies. The maximum cash award amount will be earned if the Company’s financial performance ranks above all of the Peer Companies. No award will be earned if the Company’s financial performance ranks in the bottom 25 percent of the Peer Companies. The Company has used this rigorous comparison goal for over 15 years. During that period, the Company ranked above 50 percent of the Peer Companies in 13 of the last 15 years, demonstrating excellent performance against the Peer Companies and providing superior returns to stockholders.

The remaining portion of the award for the Chief Executive Officer and the Named Executive Officers is based upon individual business unit and leadership goals determined by the Committee for the Chief Executive Officer and by the Chief Executive Officer for the other Named Executive Officers, measured over a three-year performance cycle. The Committee assesses goal achievement for the prior three-year period in April following completion of the applicable cycle and approves awards for the Named Executive Officers at such time. Long-term incentive cash awards are measured on a sliding scale as indicated below:

% of Goal Achieved		<75%		75%		100%		125%		150% and above
% of Target Paid		0%		50%		100%		150%		200%

Table of Contents

In April 2025, the Committee determined cash awards for the three-year period ending December 31, 2024. For the 2022-2024 LTIP cycle, the Company ranked third among the eleven Peer Companies and the Committee approved a payout of 160 percent of target on the Company Performance Goal for each Named Executive Officer.

All Named Executive Officers in the 2022-2024 LTIP cycle had goals in addition to the Company Performance Goal. The award for R. P. Feight was based 30 percent on strategic goals focused on market share growth, parts sales and PACCAR’s emerging technologies strategy development. The Committee determined that R. P. Feight exceeded each goal and approved an overall payout of 148 percent of target. The award for H. C. Schippers was based 30 percent on business unit profit at DAF and Worldwide Financial Services and 20 percent on business unit leadership. The Committee determined that H. C. Schippers met or exceeded each goal and approved an overall payout of 155.9 percent of target. The award for K. D. Baney was based 50 percent on business unit profit at Kenworth and 20 percent on business unit leadership. The Committee determined that K. D. Baney met or exceeded each goal and approved an overall payout of 168 percent of target. The award for C. M. Dozier was based 25 percent on business unit profit at Kenworth, PACCAR Australia, Brasil and Mexico, and 25 percent on business unit leadership. The Committee determined that C. M. Dozier exceeded the business unit goal and approved an overall payout of 147.5 percent of target. The award for D. C. Siver was based 25 percent on business unit profit at Peterbilt, PACCAR Parts and Dynacraft and 25 percent on business unit leadership. The Committee determined that D. C. Siver met or exceeded each goal and approved an overall payout of 155 percent of target. The Committee exercised discretion to reduce each Named Executive Officer’s maximum funding amount described below under the heading “LTIP Funding Limit” in determining payout as described above. The long-term cash awards for the 2023-2025 LTIP cycle have not been determined as of the date of this proxy statement because peer group comparison data was not available.

LTIP Funding Limit. The maximum cash portion amount that may be paid to any eligible participant in any year under the LTIP program is $7,000,000. The LTIP awards for the Named Executive Officers are subject to the conditions of payment set forth in the Long-Term Incentive Plan. Pursuant to the LTIP, the Committee established a funding limit for the 2025-2027 LTIP performance cycle equal to one percent of the Company’s cumulative net income and the maximum share of such pool assigned to the current Chief Executive Officer and the next four most highly compensated executive officers was 55.8 percent, 16.7 percent, 9.7 percent, 9.7 percent and 8.1 percent, respectively. The Committee, in its sole discretion, may reduce or eliminate (but not increase) any award otherwise payable to the Named Executive Officers under each officer’s funding maximum based on the achievement of the LTIP goals, an assessment of individual performance and other factors within the discretion of the Committee.

Stock options. The Committee includes stock options in its compensation program because stock options link the interests of executives directly with stockholders’ interests through increased individual stock ownership. Stock options are granted by the Committee once each year on a predetermined date after the fourth-quarter earnings release and are not repriced, backdated or purchased by the Company. The number of options is determined by multiplying the executive’s base salary on the grant date by a target award percentage and dividing by the average closing price of the Company’s stock on the first five trading days of the year. The exercise price of stock options is the closing price of the Company’s stock on the date of grant. Options become exercisable at the end of a three-year vesting period and expire ten years after the date of grant. A participant who elects to retire at age 62 with 15 years of service, but before age 65, has ten years from date of grant to exercise vested options and a prorated number of stock options which are not otherwise exercisable at the time of retirement will become immediately exercisable, and may thereafter be exercised by the participant at any time within ten years after the date of grant. A participant who retires at or after age 65 has the full term to exercise options and unvested options will continue to vest. Vesting may be accelerated in the event of a change in control.

The Committee granted stock options on February 3, 2025 in accordance with the target award percentages listed on page 20. All stock options granted in 2025 vest and become exercisable on January 1, 2028 and remain exercisable until February 3, 2035, unless the participant’s employment terminates earlier for reasons other than retirement or the participant is demoted to an ineligible position.

Annual restricted stock program. Performance-based restricted stock and RSUs are included in the program because they link the interests of executives directly with stockholders’ interests through increased individual stock ownership and add a performance goal that is tied to the success of the Company’s business. The Committee sets a Company performance goal and makes dollar-denominated restricted stock or RSU grants, subject to the achievement of the annual performance goal, on or before the first 90 days of the year. If the Committee determines that the annual performance goal was achieved, the number of restricted shares or RSUs is determined and settled by multiplying the executive’s base salary by the target award percentage and dividing by the average closing price of the Company’s stock on the first five trading days of the following year. The restricted stock or RSUs vest 25 percent on the first day of the month following the first anniversary of the grant and an additional 25 percent on each succeeding first of January. Unvested awards are forfeited upon termination unless termination is by reason of death, disability or retirement. All awards vest immediately upon a change in control. Each Named Executive Officer has the same rights as all other stockholders to vote the restricted shares and to receive cash dividends. Named Executive Officers may elect to receive RSUs instead of restricted stock on the above terms, except that RSUs do not have voting rights and receive dividend equivalents that are credited to a stock unit account.

The performance goal for 2025 was five percent after-tax return on revenue. The goal was determined based on the average return on revenues of heavy- and medium-duty truck manufacturers in Europe and North America. Return on revenue is defined as net income divided by total revenues.

On February 6, 2026, the Committee determined that the 2025 performance goal was achieved and approved the grant of restricted stock or RSUs consistent with the target award percentages listed on page 20. The restricted stock or RSUs granted on February 6, 2026 for 2025 performance are included in footnote (b) on page 27.

Compensation of the Chief Executive Officer

The Committee applies the same compensation philosophy, policies and comparative data analysis to the Chief Executive Officer as it applies to the other Named Executive Officers. The Chief Executive Officer is the only officer with overall responsibility for all corporate functions and, as a result, has a greater percentage of his total compensation based on the overall financial performance of the Company. Under his leadership in 2025, the Company achieved $28.44 billion annual revenues and $2.38 billion net income.

Deferral of Annual and Long-Term Performance Awards

The Committee administers a Deferred Compensation Plan described on page 31, which allows eligible employees to defer cash incentive awards into an income account or a stock unit account. Both accounts are unfunded and unsecured. This program provides tax and retirement planning benefits to participants and market-based returns on amounts deferred. Certain deferrals are subject to Internal Revenue Code Section 409A. Payouts from the income account are made in cash either in a lump sum or in a maximum of 15 annual installments in accordance with the executive’s payment election. Stock unit accounts are paid out in Company stock either in a one-time distribution or in a maximum of 15 annual installments in accordance with the executive’s payment election. Participation in the Deferred Compensation Plan is voluntary.

Stock Ownership Guidelines

The Company’s executive officers are required to meet stock ownership guidelines that reflect alignment of senior executives’ long-term goals with that of the Company stockholders. The minimum number of shares of Company stock and deferred stock units expected to be held by each category of executive officer is as follows: the Chief Executive Officer — five times base salary; other Named Executive Officers — three times base salary; and other executive officers — one times base salary. Company executive officers have three years from the first January after the executive first holds the qualifying position to attain the stock ownership target.

23

Table of Contents

The Committee reviews compliance with the guidelines each year. Executives who are not in compliance with the ownership threshold must retain all vested stock awards and at least 50 percent of after-tax shares acquired through the exercise of stock options until the applicable stock ownership threshold is met. As of January 1, 2026, all executive officers either had achieved the stock ownership threshold or were within the time allowed to meet it.

Effect of Post-Termination Events

The Company has no written employment agreement with its Chief Executive Officer or with any Named Executive Officer. Executive compensation programs provide full benefits only if a Named Executive Officer remains with the Company until normal retirement at age 65. In general, upon a termination without cause, a Named Executive Officer retains vested benefits but receives no enhancements or severance. In a termination for cause, the executive forfeits all benefits except those provided under a qualified pension plan. Long-term cash incentives are prorated upon retirement at age 62, with 15 years of service, or death and are awarded at the maximum level upon a change in control. The annual restricted stock/RSU grants become fully vested at retirement, death or a change in control. The Company believes that the benefits described in this section help it attract and retain its executive officers by providing financial security in the event of certain qualifying terminations of employment or a change in control of the Company. The fact that the Company provides these benefits does not materially affect other decisions that the Company makes regarding compensation. The Company maintains a separation pay plan for all U.S. salaried employees that provides a single payment of up to six months of base salary in the event of job elimination in a business restructuring or reduction in the workforce. The Named Executive Officers are eligible for the benefit on the same terms as any other eligible U.S. salaried employee.

Effect of Tax Treatment

While the Committee considers the deductibility of compensation as one factor in determining executive compensation, the Committee believes that it is in the best interests of our stockholders to structure a program that is considered to be the most effective in attracting, motivating and retaining key executives.

Compensation Forfeiture

In the event the Board determines that an executive officer has engaged in misconduct detrimental to the Company, including fraudulent conduct which results in a material inaccuracy in the Company’s financial statements, the officer may be terminated for cause and all unpaid compensation forfeited. Cause is defined to include: an act of embezzlement, fraud or theft; the deliberate disregard of the rules of the Company or a subsidiary; any unauthorized disclosure of any secret or confidential information of the Company or a subsidiary; any conduct which constitutes unfair competition with the Company or a subsidiary; or inducing any customer of the Company or a subsidiary to breach any contracts with the Company or a subsidiary. The provisions do not allow for recoupment of base salary which has been previously paid.

The Company maintains an incentive compensation recovery policy in accordance with Rule 10D-1 of the Exchange Act and Nasdaq Rule 5608 that requires the Company to recover excess incentive compensation that was paid to an executive officer based in whole or in part on financial results that were subject to a restatement of the Company’s financial statements. Additionally, in the event the Board determines that an executive officer has engaged in fraud that has caused or substantially contributed to the restatement, the Board in its discretion may recover from the officer or former officer any or all incentive compensation based in whole or in part on the financial results that were subject to the restatement.

Conclusion

The Company’s compensation programs are designed and administered in a manner consistent with its conservative executive compensation philosophy and guiding principles. The programs emphasize the retention of key executives and appropriate rewards for excellent results. The Committee monitors these programs in recognition of the dynamic marketplace in which the Company competes for talent. The Company will continue to emphasize Pay for Performance and equity-based incentive programs that compensate executives for results that are consistent with generating outstanding performance for its stockholders.

Compensation Committee Report

The Committee reviewed and discussed the Compensation Discussion and Analysis Section (“CD&A”) for 2025 with management. Based on the Committee’s review and its discussions with management, the Committee recommends to the Board of Directors that the CD&A be included in the Company’s proxy statement for the 2026 Annual Meeting and incorporated by reference into the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

The Company’s U.S. qualified noncontributory retirement plan has been in effect since 1947. The Named Executive Officers participate in this plan on the same basis as other U.S. salaried employees. Employees are eligible to become a member in the plan after completion of 12 months of employment with at least 1,000 hours of service. The plan provides benefits based on years of service and salary. Participants are vested in their retirement benefits after five years of service.

29

Table of Contents

The benefit for each year of service, up to a maximum of 35 years, is equal to one percent of the highest average salary plus 0.5 percent of highest average salary in excess of the Social-Security-covered compensation level. Highest average salary is defined as the average of the highest 60 consecutive months of an employee’s cash compensation, which includes base salary and annual incentive cash compensation, but it excludes compensation under the LTIP. The benefits are not subject to any deduction for Social Security or other offset amounts. Benefits from the plan are paid as a monthly single-life annuity or, if married, actuarially equivalent 50 percent, 75 percent or 100 percent joint and survivor annuity options are also available. Survivor benefits based on the 50 percent joint and survivor option will be paid to an eligible spouse if the employee is a vested member in the plan and dies before retirement.

The Company’s unfunded U.S. Supplemental Retirement Plan (“SRP”) provides a retirement benefit to those affected by the maximum benefit limitations permitted for qualified plans by the Internal Revenue Code and to those deferring incentive compensation bonuses. The benefit is equal to the amount of normal pension benefit reduction resulting from the application of maximum benefit and salary limitations and the exclusion of deferred incentive compensation bonuses from the retirement plan benefit formula. Benefits from the plan are paid as a lifetime monthly annuity or a single lump-sum distribution at the executive’s election and the benefits will be paid at the later of: (1) termination of employment or (2) the date the participant attains age 55. If the participant dies before the supplemental benefit commencement date, the participant’s surviving spouse will be eligible to receive a survivor pension for the amount by which the total survivor pension benefit exceeds the surviving spouse’s retirement plan benefit. Executives terminated for cause, as defined in the Plan, forfeit all SRP benefits.

Normal retirement age under both plans is 65, and participants may retire early between ages 55 and 65 if they have 15 years of service. For retirement at ages 55 through 61 with 15 years of service, pension benefits are reduced four percent per year from age 65. For retirement at or after age 62 with 15 years of service, there is no reduction in retirement benefits. As of December 31, 2025, R. P. Feight, B. J. Poplawski, K. D. Baney, C. M. Dozier and D. C. Siver are eligible for a reduced early retirement benefit.

H. C. Schippers’ transition agreement provides that if he works for PACCAR in the United States for at least five years, then an additional year of credited service will be added to his nonqualified retirement benefit for each fully completed year of service.

H. C. Schippers participated in the Company’s pension program in the Netherlands on the same basis as other DAF Eindhoven employees. DAF participates in the Metal and Electrical Engineering Industry Pension Fund (the “Fund”), a multi-employer defined benefit plan covering employees of the country’s metal industry. The benefit is based on a percentage of the career average salary up to the annually indexed salary maximum multiplied by years of service up to age 68 per January 1, 2025. In 2025, thPe percentage of salary was 1.875 percent and the yearly indexed maximum salary was €95,236. Survivor benefits include a pension up to 70 percent of the participant’s benefit. Participants contribute 50 percent of the premiums and are vested from date of hire. Normal retirement benefits begin at age 68 and participants may retire early at or after age 55 with reduced benefits.

The Pension Benefits table shows the present value of the accrued retirement benefits for the Named Executive Officers under the Company’s retirement plan and SRP based on highest average salary and service as of December 31, 2025 and the present value of H. C. Schippers’ accrued benefits under the Fund and his transition agreement. Present value calculations for each Named Executive Officer under age 62 assumed that each remains employed until age 62, if eligible for unreduced benefits, or age 65 if not. Additional assumptions include the use of FTSE Discount Pension Curve as of December 31, 2025 and December 31, 2024 to discount future payouts (equivalent to a discount rate of 5.55 percent and 5.50 percent, respectively, for the Plan in aggregate). The mortality assumptions use the RP-2012 White Collar Male Mortality Table projected generationally with projection scale MP-2021.

2025 Nonqualified Deferred Compensation

The following table provides information about the deferred compensation accounts of the Named Executive Officers as of December 31, 2025. Amounts deferred reflect cash awards payable in prior years but voluntarily deferred by the executive.

(a)To the extent required to be reported, all cash awards were reported as compensation to the Named Executive Officer in the Summary Compensation Table for previous years.

The Company’s Deferred Compensation Plan provides all eligible employees, including the Named Executive Officers, an opportunity to voluntarily defer all or part of the cash awards earned and payable under the LTIP and the IC Plan. The Company makes no contributions to the Deferred Compensation Plan. Accounts are credited with interest or dividend equivalents as described below.

A portion of the amount in the 2025 Aggregate Earnings column is reported in the Summary Compensation Table for the Named Executive Officers as follows: D. C. Siver $1,476. Certain of the Named Executive Officers have elected to defer into an income account, a stock unit account or any combination of each. Deferral elections were made in the year before the award was payable. Cash awards were credited to the income account on the date the award was payable and interest is compounded monthly on the account balance based on the simple combined average of the daily Aa Industrial Bond yield average for the immediately preceding month. The Named Executive Officer may elect to be paid out the balance of the income account in a lump sum or in up to 15 substantially equal annual installments. Cash awards credited to the stock unit account are treated as if they had been invested in the Company’s common stock on the date the cash award is payable. Dividend equivalents are credited to the stock unit account and treated as if they had been invested in the Company’s common stock on the date the dividend is paid to stockholders. A Named Executive Officer’s stock unit account is paid out in Company stock either in a one-time distribution or in a maximum of 15 annual installments, at the election of the Named Executive Officer. Payment of a Named Executive Officer’s income account and stock unit account will be made or commence to be made in the first January following the Named Executive Officer’s termination of employment, unless the Named Executive Officer elects to have payment occur or commence on an earlier date, except that payment on account of termination of employment to a participant who is a specified employee for purposes of Section 409A on the Internal Revenue Code will not be made prior to the first day of the month following the six-month anniversary of termination of employment. If the Named Executive Officer dies before his or her interest under the Deferred Compensation Plan has been distributed, his or her interest will be distributed to his or her beneficiary. A Named Executive Officer will forfeit his or her entire interest under the Deferred Compensation Plan if he or she is terminated by the Company for cause or if the Named Executive Officer refuses to provide advice or counsel to the Company or any of its subsidiaries after the Named Executive Officer’s termination of employment.

Termination for Cause. If a Named Executive Officer had been terminated for “cause,” as defined in the Company’s LTIP Administrative Guidelines, all unpaid cash incentives under the IC Plan and the LTIP, stock options (vested and unvested), restricted stock/RSUs, deferred compensation balances and accrued SRP benefits would have been immediately forfeited.

Resignation or Termination Without Cause. If a Named Executive Officer had resigned or been terminated without cause, all unpaid incentives under the IC Plan and the LTIP, unvested stock options and restricted stock/RSUs would have been immediately forfeited. Vested stock options would remain exercisable for one month from the date of termination.

Deferred compensation balances, as described in the Nonqualified Deferred Compensation Table, would be paid in a lump sum or in installments according to the payment election filed by the Named Executive Officer. The Named Executive Officer may elect to have such payments made or commence in any January that is at least 12 months from the date of such payment election, but no later than the first January following the year in which the executive attains age 70-1/2.

Accrued SRP benefits described under the Pension Benefits Table would be paid in a form previously elected by the Named Executive Officer. R. P. Feight, B. J. Poplawski and C. M. Dozier would receive a single lump-sum cash payment. K. D. Baney and D. C. Siver would receive monthly annuities payable for life. If termination occurred on December 31, 2025, these payments would be made or would commence in accordance with the terms of the SRP on July 1, 2026 for each Named Executive Officer.

Table of Contents

Retirement. R. P. Feight, B. J. Poplawski, K. D. Baney, C. M. Dozier and D. C. Siver were eligible for early retirement benefits as of December 31, 2025. Deferred compensation balances and accumulated SRP benefits would have been payable for the Named Executive Officers as described above under “Resignation or Termination Without Cause.” Annual incentive compensation earned in 2025 would have been paid in the first quarter of 2026 and long-term incentive cash awards earned under the 2023-2025 performance cycle would be paid by May 2026 based on actual performance against goals. The long-term performance awards in the table reflect target awards. LTIP cash awards for incomplete cycles are prorated for retirement after age 62, with 15 or more years of service. For an officer over age 62, but before age 65, with 15 or more years of service, a prorated number of stock options will vest on retirement and will be exercisable through their original expiration date. The stock options value in the table reflects the difference between the closing market price on December 31, 2025 and the exercise price multiplied by the prorated number of unvested stock options. All outstanding restricted stock/RSUs for the Named Executive Officers who were (i) over age 62 or (ii) over age 55 with at least 15 years of service would vest in full upon retirement. The amount listed for restricted stock/RSUs in the table reflects vesting of all unvested restricted stock/RSUs for those eligible for normal or early retirement at the closing market price on December 31, 2025. The closing market price on December 31, 2025 was $109.51 per share.

Death. In the event of the death of a Named Executive Officer on December 31, 2025, beneficiaries of the Named Executive Officer would have been entitled to receive all of the benefits that would have been paid to a Named Executive Officer who had retired on that date as described above, with the following exceptions:

•Long-term incentive cash awards earned under the 2024-2026 LTIP performance cycle and the 2025-2027 LTIP performance cycle would have been paid on a prorated basis (2/3 and 1/3, respectively) following completion of the cycle, based on actual performance against goals.

•All outstanding restricted stock/RSUs would vest immediately.

Change in Control. Benefits payable in the event of a change in control on December 31, 2025 are the same as benefits payable in the event of death on the same date (as described above) with the following exceptions:

•Named Executive Officers employed on December 31, 2025 would have been entitled to a maximum IC award for 2025 (200 percent of target), a maximum long-term incentive cash award under the 2023-2025 performance cycle of the LTIP and a maximum prorated award under the 2024-2026 and the 2025-2027 performance cycles based on the number of full or partial months completed in the performance cycle. The maximum payment amounts are shown in the table above and would have been paid in a lump sum immediately following the change in control.

•All outstanding restricted stock/RSUs would vest immediately.

Deferred compensation balances would have been paid as a single lump sum in cash from the “income account” and whole shares of the Company’s common stock from the “stock account” immediately following the change in control.

CEO PAY RATIO DISCLOSURE

PACCAR identified its median employee using the employee population on October 1, 2023 and used total cash compensation as the appropriate “consistently applied compensation measure” in order to determine the median paid employee. Total cash compensation paid to each employee for the period from January 1, 2025 to September 30, 2025 was reviewed for all global employees. PACCAR believes total cash compensation reasonably reflects annual compensation. PACCAR used the same employee for 2025 because there has been no change in its employee population or employee compensation arrangements that it reasonably believes would result in a significant change to its pay ratio disclosure. The identified median employee’s total annual compensation will be compared to the CEO’s total annual compensation, both as calculated in accordance with the requirements of the Summary Compensation Table. The CEO’s cash award earned for the 2023-2025 LTIP cycle will not be determined until April 27, 2026. The CEO pay ratio for 2025 will be disclosed on Form 8-K following such determination. The CEO pay ratio for 2024 was 189 to 1.

(d)Total shareholder return is based on a $100 investment as of December 31, 2020 and determined using S&P’s calculations of the cumulative total shareholder return on the Company’s common stock and the stock of each of the Peer Companies for the applicable year, weighted according to its respective capitalization at the beginning of each period, with dividends reinvested on a monthly basis.

(e)The Peer Group for 2025 is the same as for 2024. Total shareholder return reflects revisions to the composition of the Peer Group in prior years due to (i) acquisitions of prior Peer Companies by current Peer Companies, and (ii) the inclusion of Peer Companies only for full years during which they were publicly traded.

ITEM 2: ADVISORY RESOLUTION TO APPROVE EXECUTIVE COMPENSATION (“SAY ON PAY”)

In 2025, PACCAR stockholders voted on an advisory basis to approve the compensation of the Named Executive Officers as required by Section 14A of the Exchange Act (known as a “Say on Pay” vote), with over 93 percent of the shares voted in favor of “Say on Pay.”

In 2025, the Company reported net sales and revenues of $28.44 billion and net income of $2.38 billion. The Company has achieved 87 consecutive years of net income, paid annual dividends every year since 1941 and delivered a total stockholder return of 8 percent in 2025. PACCAR’s average annual total return to stockholders has exceeded that of the S&P 500 Index over the last 5-, 10- and 20-year periods ended December 31, 2025.

2025 Financial Results and Business Highlights:

•Consolidated net sales and revenues of $28.44 billion

•Net income of $2.38 billion

•Record year-end stockholders’ equity of $19.26 billion

•Cash dividends declared of $1.43 billion

•8.4 percent after-tax return on revenues

•Record PACCAR Parts revenue of $6.87 billion

•PACCAR Parts pre-tax income of $1.67 billion

•Financial Services assets of $22.80 billion

•Financial Services pre-tax income of $485.4 million

•Cash provided by operations of $4.42 billion

•Delivered 144,200 vehicles worldwide

The Company’s executive compensation program provides excellent incentives for executives to deliver superior short- and long-term business performance and stockholder returns. The Board of Directors recommends an advisory vote to APPROVE the compensation of the Named Executive Officers (“Say on Pay”).

The Compensation Discussion and Analysis (“CD&A”) beginning on page 15 of this Proxy Statement describes in detail the Company’s 2025 executive compensation program and the decisions made by the Compensation Committee. Highlights of the CD&A include the following:

•Incentive-based pay (“Pay for Performance”) represents approximately 68 percent of the Named Executive Officers’ target total compensation, with approximately 51 percent related to long-term incentives and 17 percent related to achievement of challenging annual performance goals.

•The Named Executive Officers earn long-term equity awards in the form of restricted stock/RSUs and stock options subject to multiple-year vesting requirements. The Company believes these awards ensure that a significant portion of the executives’ compensation reflects long-term growth in stockholder value.

•Executive officer stock ownership guidelines align executives’ long-term goals with that of stockholders.

•None of the Named Executive Officers has an employment agreement or severance arrangement.

“RESOLVED, THAT THE COMPENSATION PAID TO THE COMPANY’S NAMED EXECUTIVE OFFICERS, AS DISCLOSED PURSUANT TO ITEM 402 OF REGULATION S-K INCLUDING THE COMPENSATION DISCUSSION AND ANALYSIS, COMPENSATION TABLES AND NARRATIVE DISCUSSION, IS HEREBY APPROVED.”

This advisory vote is an excellent method for stockholders to provide input on the Company’s executive compensation program. Although the vote is not binding on the Company, the Board and Compensation Committee value the opinions expressed by stockholders and will consider the outcome of the vote when evaluating future executive compensation decisions.

The following line graph compares the yearly percentage change in the cumulative total stockholder return on the Company’s common stock to the cumulative total return of the S&P 500 Index and the return of the industry peer group of companies identified below (the “Peer Group Index”) for the last five fiscal years ended December 31, 2025. The Peer Group Index includes AGCO Corporation, Caterpillar Inc., Cummins Inc., Daimler Truck Holdings AG (effective January 1, 2022), Deere & Company, Eaton Corporation, Iveco Group N.V. (effective January 1, 2022), Oshkosh Corporation, TRATON SE, Terex Corporation and AB Volvo. S&P has calculated a return for each company in the Peer Group Index weighted according to its respective capitalization at the beginning of each period with dividends reinvested on a monthly basis. Management believes that the identified companies and methodology used in the graph for the Peer Group Index provide a better comparison than other indices available. The comparison assumes that $100 was invested December 31, 2020, in the Company’s common stock and in the stated indices and assumes reinvestment of dividends.
