USE OF PROCEEDS

The proceeds from the sale of the common stock to which this prospectus relates are solely for the account of the Selling Stockholder. Honeywell will not receive any of the proceeds from such sales.

SELLING STOCKHOLDER

This prospectus covers the resale, from time to time, by the Selling Stockholder, of shares of common stock, par value $1.00 per share, of Honeywell. The number of shares to be sold by the Selling Stockholder shall be specified from time to time in a prospectus supplement.

In 2024, Honeywell is not required to make any contributions to its U.S. pension plans to satisfy minimum statutory funding requirements. Honeywell does not presently anticipate making any voluntary contributions of Honeywell common stock to the Selling Stockholder. The shares of common stock to which this prospectus relates (i) have been or will be contributed by Honeywell to the Selling Stockholder, from time to time, in one or more private transactions, or (ii) may be purchased by the Selling Stockholder in the open market.

The Selling Stockholder is a tax-qualified trust that holds the assets for most of our U.S. defined benefit pension plans. We make contributions to the Selling Stockholder from time to time in amounts that are not less than the minimum amount required under, or more than the maximum deductible amount permitted by, the Internal Revenue Code.

The registration of the shares of common stock does not necessarily mean that the Selling Stockholder will sell all or any of the shares of common stock registered by the registration statement of which this prospectus forms a part. The Selling Stockholder may offer and sell all or any portion of the shares of common stock covered by this prospectus and any applicable prospectus supplement from time to time, but is under no obligation to offer or sell any such shares. Because the Selling Stockholder may sell, transfer or otherwise dispose of all, some or none of the shares of common stock covered by this prospectus, or may acquire additional shares from us or in the market in the future, we cannot determine the number of such shares of common stock that will be sold, transferred or otherwise disposed of by the Selling Stockholder or the amount or percentage of shares of common stock that will be held by the Selling Stockholder upon termination of any particular offering. See “Plan of Distribution.” Additionally, from time to time the Selling Stockholder may sell shares of common stock to the Company in one or more privately negotiated transactions.

The shares of common stock are held in the custody of The Northern Trust Company, 50 South LaSalle Street, Chicago, IL 60675, as the Trustee. Honeywell currently has on-going banking relationships with the Trustee in the ordinary course of business and expects to continue to have similar relationships with the Trustee in the future. The shares of common stock are held in a separate investment account at the Trustee. An independent, third party investment fiduciary has been chosen by the Pension Investment Committee (“PIC”) under a delegation of authority from the Retirement Plans Committee of the board of directors of Honeywell and appointed by the PIC to instruct the Trustee as to any disposition of the shares of common stock. The investment fiduciary has sole authority to manage the shares of common stock, subject to general investment criteria established by the PIC, and the sole power to vote and to dispose of the shares of common stock.

15,677,997 shares of common stock are the only shares of common stock owned by the Selling Stockholder as of October 24, 2024.

DESCRIPTION OF COMMON STOCK

General

As of the date of this prospectus, we are authorized to issue up to 2,000,000,000 shares of common stock. As of September 30, 2024, we had approximately 958 million shares of common stock issued (including approximately 307.4 million shares held in treasury). EQ Shareowner Services, a division of Equiniti Trust Company, is the transfer agent and registrar for our common stock. Shares of common stock are listed on the Nasdaq Stock Market under the symbol “HON.”

The following summary is not complete. You should refer to the applicable provision of Honeywell’s charter and by-laws and to Delaware corporate law for a complete statement of the terms and rights of our common stock.

Dividends

Holders of common stock are entitled to receive dividends when, as and if declared by the board of directors, out of funds legally available for their payment, subject to the rights of holders of any preferred stock outstanding.

Voting Rights

Each holder of common stock is entitled to one vote per share. Subject to any rights of the holders of any series of preferred stock pursuant to applicable law or the provision of the certificate of designations creating that series, all voting rights are vested in the holders of shares of common stock. Holders of shares of common stock have noncumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of directors can elect 100% of the directors, and the holders of the remaining shares voting for the election of directors will not be able to elect any directors.

Rights Upon Liquidation

In the event of Honeywell’s voluntary or involuntary liquidation, dissolution or winding up, the holders of common stock will be entitled to share equally in any of Honeywell’s assets available for distribution after the payment in full of all debts and distributions and after the holders of any series of outstanding preferred stock have received their liquidation preferences in full.

Other Rights

Holders of shares of common stock are not entitled to preemptive rights. Shares of common stock are not convertible into shares of any other class of capital stock. If we merge or consolidate with or into another company and as a result our common stock is converted into or exchangeable for shares of stock, other securities or property (including cash), all holders of common stock will be entitled to receive the same kind and amount of consideration per share of common stock.

Possible Anti-Takeover Provisions

Honeywell’s charter and by-laws provide:

3

Any of these provisions could delay, deter or prevent a tender offer for or attempted takeover of Honeywell.

Our charter permits us to issue up to 40,000,000 shares of preferred stock with terms that may be set by our board of directors or a committee of the board. That preferred stock could have terms that could delay, deter or prevent a tender offer or takeover attempt of Honeywell.

Under Delaware law, an acquirer of 15% or more of our shares of stock must wait three years before a business combination with us unless one of the following exceptions is available:

Honeywell’s by-laws provide that, unless Honeywell consents in writing to the selection of an alternative forum, a state or federal court located within the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of Honeywell, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of Honeywell to Honeywell or Honeywell’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or (iv) any action asserting a claim governed by the internal affairs doctrine. Honeywell’s by-laws also provide that any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of Honeywell will be deemed to have notice of and consented to the exclusive forum provisions described above.

PLAN OF DISTRIBUTION

The Selling Stockholder may, upon the instructions from the independent, third party investment fiduciary, sell all or a portion of the shares of common stock to which this prospectus relates either (1) on the markets in which our common stock is traded or (2) through underwriters or in privately negotiated transactions.

Market sales may be effected from time to time in one or more transactions (which may involve block transactions):

4

Such transactions may be effected by the Selling Stockholder, upon instructions from the independent, third party investment fiduciary, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or at fixed prices. The Selling Stockholder will act independently of us with respect to the timing, manner and size of each sale.

The Selling Stockholder may, upon instructions from the independent, third party investment fiduciary, effect such transactions by selling shares of common stock to or through broker-dealers. Such broker-dealers may receive compensation in the form of discounts or commissions from the Selling Stockholder and may receive commissions from the purchasers of shares for whom they may act as agent in amounts to be negotiated. Such compensation may be received if the broker-dealer acts as either an agent or as a principal. The Selling Stockholder does not expect these discounts or commissions to exceed what is customary in the types of transactions involved. Any offering price, and any discounts or concessions allowed or reallowed or paid to dealers, may be changed from time to time.

The Selling Stockholder may, upon instructions from the independent, third party investment fiduciary, cause such transactions to be conducted via an underwritten offering. In the case of an underwritten offering, a prospectus supplement with respect to an offering of shares of common stock will set forth the terms of the offering of the shares of common stock, including the name or names of the underwriters, the purchase price and the proceeds to the Selling Stockholder from such sale, any underwriting discounts and other items constituting underwriters’ compensation, the public offering price and any discounts or concessions allowed or reallowed or paid to dealers. The shares of common stock will be acquired by the underwriters for their own account and may be sold from time to time in one or more transactions at a fixed public offering price determined at the time of sale. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase shares of common stock will be subject to conditions precedent and the underwriters will be obligated to purchase all the shares of common stock if any are purchased. The public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

The aggregate proceeds to the Selling Stockholder will be the purchase price of the shares of common stock less discounts and commissions, if any.

In offering the shares of common stock covered by this prospectus, the Selling Stockholder and any broker-dealers, underwriters or agents who execute sales for the Selling Stockholder may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), in connection with such sales. Any profits realized by the Selling Stockholder and the compensation of any broker-dealer, underwriter or agent may be deemed to be underwriting discounts and commissions. We know of no existing arrangements between the Selling Stockholder and any broker-dealer, underwriter or other agent relating to the sale or distribution of the shares of common stock. Honeywell has not engaged any broker-dealer, underwriter or agent in connection with the distribution of the shares of common stock.

Under the terms of any particular transactions, dealers, underwriters or agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents, dealers or underwriters may be required to make in respect thereof.

Agents and underwriters may be engaged in transactions with, or perform commercial or investment banking or other services for, us or our subsidiaries or affiliates, in the ordinary course of business.

5

All of the shares of common stock will be listed on the Nasdaq Stock Market. Any agents or underwriters to whom the shares of common stock are sold may make a market in our common stock. However, those agents or underwriters will not be obligated to do so and may discontinue any market making at any time without notice.
