General

The Honeywell Puerto Rico Savings Plan (the “Plan”) is a defined contribution plan for certain employees of Honeywell International Inc. (“Honeywell” or the “Company”), ADI of Puerto Rico, Inc. and Honeywell Aerospace de Puerto Rico, Inc. (together with the Company, the “Employer”). It is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended, (“ERISA”) and the Puerto Rico (“PR”) Internal Revenue Code of 2011, as amended in Section 1081.01 (“PR Code”). The following represents a summary of key provisions of the Plan but does not purport to be complete and is qualified in its entirety by the terms of the Plan. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

Administration

The Company’s Vice President – Global Total Rewards is the Plan Administrator and has full discretionary authority and power to control and manage the administrative aspects of the Plan, including, but not limited to, the power to adopt rules of procedure and regulations necessary for the proper and efficient administration of the Plan and the power to enforce the terms of the Plan it adopts. The Savings Plan Investment Committee has the full power and discretionary authority to manage the investments of the Plan, including but not limited to the power to appoint and remove trustees and monitor trustee performance. The trustee and custodian of the Plan is The Northern Trust Company (the “Trustee”). The trustee of the Plan is Banco Popular de Puerto Rico (the “Trustee”) and the custodian of the Plan is The Northern Trust Company (the “Custodian”). Administration services for the Plan are provided by Fidelity Investments Institutional Operations Company. The Plan has a Puerto Rico based trust (“the Honeywell Puerto Rico Savings Plan Trust”) that participates and invests the Plan’s assets in the Honeywell Savings and Ownership Plan Master Trust.

Contributions and Vesting

Participants may elect to contribute from 1 percent to 30 percent before-tax of their “base pay” and also 1 percent to 10 percent after-tax of their “base pay” as defined in the Plan document during each pay period, subject to certain restrictions for “highly compensated employees”, as defined in the Plan document. Contributions are permitted to be made either on a before-tax or after-tax basis, or a combination of both, and may be directed into any investment option available within the Plan. The investment options for participants consist of white-labeled, multi-managed funds that are proprietary to the Plan. In addition to regular before-tax or after-tax contributions, eligible participants may also contribute up to $1,500 per year in catch-up contributions if they are or will attain age 50 by December 31^st of the respective plan year and are contributing at least 10 percent on a before-tax basis to the Plan or have contributed the maximum regular before-tax contributions to the Plan.

The Company matches up to 52.50 percent of the first 6 percent of base pay that the participant contributes to the Plan (excluding rollover and catch-up contributions). The Company’s matching contributions are initially invested in the Honeywell Common Stock Fund. Vested participants may subsequently direct such matching contributions into any investment option available within the Plan.

Employer matching contributions are made annually in a lump sum by the end of the January following the calendar year-end. Participants must be actively employed on December 15^th, and if not, disabled or deceased to receive the annual match. There is no minimum service requirement to receive the annual match. Accordingly, the Statement of Net Assets Available for Benefits at December 31, 2025 and Statement of Changes in Net Assets Available for Benefits for the year ended December 31, 2025 include $2,345,000 for company matching contributions earned in 2025 and paid by the Company to the Plan in January 2026.

Participants have a full and immediate vested interest in the portion of their accounts contributed by them and the earnings on such contributions. A participant will become 100 percent vested in any Employer contributions upon completion of three years of vesting service or upon attainment of age 65 while an employee of the Employer or an affiliated company. In addition, a participant’s account will become 100 percent vested if the participant’s termination with the Employer or an affiliated company was due to any one of the following (i) retirement under the terms of an Employer pension plan in which

Certain expenses relating to the administration of the Master Trust and managing the investment funds established thereunder are borne by certain businesses of the Employer, not by the participating Plan. Administrative expenses of the Plan are paid by the Plan or the plan sponsor, as provided in the Plan document. Participants pay administrative costs for loans, distributions and qualified domestic relation orders.

The individual assets of the Master Trust’s separately managed portfolios and multi-manager funds are held in the name of the Master Trust (i.e., the Master Trust owns the underlying securities) and are considered separately as individual investments for accounting and financial statement reporting purposes.

The Master Trust owns 100% of the underlying assets of the following separately managed portfolios and multi-manager funds and the underlying investments of each are included in Note 4:

Global REIT Fund
Growth Equity Fund
International Stock Fund
Investment Grade Bond Fund
Short-Term Fixed Income Fund
Small to Mid-Cap Stock Fund
Value/Yield Equity Fund
Honeywell Common Stock Fund

The Plan’s investments are held in the Master Trust, which is commingled with the assets of the Honeywell 401(k) Plan, the Honeywell Secured Benefit Plan and the Intermec FSSP Spinoff Plan. Each participating plan’s interest in the Master Trust is divided based on the participants’ investment elections. The allocation of income and expenses is based upon each plan’s specific interests in the underlying plan investments, which are based upon participant-direction and Company direction of the investments. The interest and dividends and the net depreciation or appreciation in the fair value of investments are allocated to the individual accounts on a daily basis based upon the individual accounts’ equitable share of the various investment funds that comprise the Master Trust. The total interest of the Plan is determined as the sum of the individual account balances of the Plan.

The Plan provides for both participant-directed and nonparticipant-directed investment programs. Employer matching contributions are initially invested in the Company’s common stock, which is a nonparticipant-directed investment option. Participants may subsequently transfer these amounts to other investment options at their discretion once vested.

The Master Trust is invested in the Company’s common stock which qualifies as an exempt party-in-interest transaction. During the year ended December 31, 2025, the Master Trust’s investment in the Company’s common stock included purchases of approximately $187 million, sales of approximately $516 million, realized gains of approximately $241 million (realized gains of approximately $2 million by the Plan), unrealized gain of approximately $579 million and dividend income of approximately $79 million. The Master Trust invests in short term investment funds managed by the Custodian. These related transactions qualify as an exempt party-in-interest transactions.

The Company is both the plan sponsor and a party to the Master Trust, therefore the Master Trust investment and the Plan’s interest of $23 million in the Company’s common stock qualifies as a related party transaction, along with the dividend income of $502 thousand earned by the Plan on this investment.

The Plan provides for various investment options. Investment securities are exposed to certain risks, such as interest rate, market, liquidity and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the value of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits. The Plan’s exposure to a concentration of credit risk is limited by the opportunity to diversify investments across multiple participant-directed fund elections including active and passively managed funds covering multiple asset classes. Additionally, the investments within each participant-directed fund election are further diversified into varied financial instruments, with the exception of the Honeywell Common Stock Fund, which primarily invests in a single security.

The Plan is designed and intended to be qualified under Section 1165 of the Puerto Rico Internal Revenue Code of 1994, as amended (the “1994 PR Code”), and Section 1081.01(a) of the Internal Revenue Code for a New Puerto Rico, Act No. 1 of January 14, 2011, as amended from time to time (the “2011 PR Code”). The Plan has received a favorable determination letter from the Puerto Rico Treasury Department as to its qualified status under the 1994 PR Code and the 2011 PR Code. The Trust associated with the Plan is intended to be exempt from Puerto Rico income taxation. Pursuant to the provisions of Section 1165(a) of the 1994 PR Code and Section 1081.01(a) of the 2011 PR Code,

The Plan has evaluated subsequent events through the date the financial statements were issued and has identified the following events requiring disclosure. Effective April 1, 2026, in anticipation of the spin-off of Honeywell Aerospace Inc. from the Company, which is expected to be finalized on June 29, 2026, active participants expected to be employed by the new Honeywell Aerospace Inc. entity (or its Puerto Rican subsidiary) following the spin-off ceased participation in the Plan and became participants of the Honeywell Aerospace Puerto Rico Savings Plan (the “Aerospace PR Plan”). In connection with this transfer, $83,125 thousand of account balances of such participants will transfer from the Master Trust to the master trust of the Aerospace PR Plan.
