Under the Investment Agreement, the selling shareholder agreed to make an equity investment in KeyCorp’s common shares in two separate tranches, with the closing of each tranche subject to certain specified conditions.

The selling shareholder may from time to time offer and sell pursuant to this prospectus and any applicable prospectus supplement or pricing supplement any or all of the common shares that have been issued to it.

The table below sets forth the name of the selling shareholder, the number of common shares beneficially owned by the selling shareholder and the number of common shares that such selling shareholder may offer pursuant to this prospectus. The information set forth below is based on information provided by or on behalf of the selling shareholder prior to the date hereof. Information concerning the selling shareholder may change from time to time.

The amounts and percentages of common shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities.

Under these rules, more than one person may be deemed beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. Percentages in the table below are based on 1,079,368,644 common shares outstanding as of May 31, 2026.

However, the selling shareholder may sell all, some or none of the common shares offered pursuant to this prospectus and may sell some or all of its common shares pursuant to an exemption from the registration provisions of the Securities Act of 1933, as amended (the “Securities Act”).

⁽²⁾	Based solely upon information provided by the selling shareholder in connection with the filing of this prospectus. The reported address of the selling shareholder is 40 Temperance Street, Toronto, Ontario, M5H 0B4.

PLAN OF DISTRIBUTION

This prospectus relates to the offer and sale, from time to time, by the selling shareholder of our common shares. We are registering the resale of these common shares, but the registration of such shares does not necessarily mean that any of such shares will be offered or sold by the selling shareholder pursuant to this prospectus or at all. As used in this section, the term “selling shareholder” includes pledgees, donees, assignees, distributees, transferees or other successors-in-interest selling such shares received after the date of this prospectus from the selling shareholder as a gift, pledge, distribution or other non-sale related transfer.

The selling shareholder may, from time to time, offer our common shares at fixed prices, at market prices or varying prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices, and by a variety of methods, including the following methods:

•

one or more transactions (which may involve underwritten offerings on a firm commitment or best-efforts basis, cross sales or block transactions) on the NYSE or otherwise;

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

secondary distributions pursuant to and in accordance with the rules of the NYSE;

•

through one or more electronic trading platforms or services;

•

over-the-counter market, in negotiated transactions;

•

direct sales to one or more purchasers, including affiliates;

•

privately negotiated transactions;

•

short sales;

•

through the writing of options or other hedging transactions on the shares (whether such options are listed on an options exchange or otherwise);

•

a combination of such methods of sale; or

•

any other method permitted by applicable law.

The selling shareholder may effect such transactions by selling the common shares offered under this prospectus to or through underwriters, broker-dealers or other agents, including electronic trading platforms or similar services, and such underwriters, broker-dealers or agents may receive compensation in the form of underwriting discounts, commissions or fees from the selling shareholder or the purchasers of shares for whom they may act as agent. The selling shareholder and any underwriters, broker-dealers or agents that participate in the distribution of the common shares offered under this prospectus may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by them and any profit on the sale of registered shares may be deemed to be underwriting commissions or discounts under the Securities Act.

The selling shareholder may have agreements with underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act, and to reimburse them for certain expenses.

In connection with the sale of its common shares or interests therein, the selling shareholder may enter into derivative transactions with underwriters, broker-dealers or other financial institutions or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If any applicable additional prospectus supplement, pricing supplement or free-writing prospectus indicates, in connection with those derivative transactions, the broker-dealers or other financial institutions or third parties may sell securities covered by this prospectus, including in short sale transactions. If so, the broker-dealer or other financial institution or third party may use securities pledged by the selling shareholder or borrowed from the selling

shareholder to settle those sales or to close out any related open borrowings of shares, and may use securities received from the selling shareholder in settlement of those derivative transactions to close out any related open borrowings of shares. The selling shareholder may also enter into options or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of shares offered under this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as further supplemented or amended to reflect such transaction).

At a time a particular offering of our common shares is made, a prospectus supplement, pricing supplement or free writing prospectus may be distributed that will set forth the common shares to be sold, the name of the selling shareholders, the respective purchase prices and public offering prices, the name or names of any underwriters, dealers, brokers or agents, any applicable commissions or discounts with respect to the particular offer and any other required information.

In addition, any shares of common shares that qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than pursuant to this prospectus.

VALIDITY OF SECURITIES

Unless otherwise specified in the applicable prospectus supplement or pricing supplement, the validity of the securities in respect of which this prospectus is being delivered will be passed upon for us by Squire Patton Boggs (US) LLP, Cleveland, Ohio.

EXPERTS

The consolidated financial statements of KeyCorp for the year ended December 31, 2025 appearing in KeyCorp’s Current Report on Form 8-K dated June 3, 2026, and the effectiveness of KeyCorp’s internal control over financial reporting appearing in KeyCorp’s Annual Report on Form 10-K as of December 31, 2025 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements and KeyCorp management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2025 are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

With respect to the unaudited consolidated interim financial information of KeyCorp for the three-month periods ended March 31, 2026 and March 31, 2025, incorporated by reference herein, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report dated May 5, 2026, included in KeyCorp’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “Act”) for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the Pre-Effective Amendment No. 1 to the Registration Statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Act.

Item 15.

Indemnification of Directors and Officers.

Under Ohio law, Ohio corporations are authorized to indemnify directors, officers, employees, and agents within prescribed limits and must indemnify them under certain circumstances. Ohio law does not provide statutory authorization for a corporation to indemnify directors, officers, employees, and agents for settlements, fines, or judgments in the context of derivative suits. However, it provides that directors (but not officers, employees, and agents) are entitled to mandatory advancement of expenses, including attorneys’ fees, incurred in defending any action, including derivative actions, brought against the director, provided the director agrees to cooperate with the corporation concerning the matter and to repay the amount advanced if it is proved by clear and convincing evidence that his act or failure to act was done with deliberate intent to cause injury to the corporation or with reckless disregard to the corporation’s best interests.

Ohio law does not authorize payment of judgments to a director, officer, employee, or agent after a finding of negligence or misconduct in a derivative suit absent a court order. Indemnification is required, however, to the extent such person succeeds on the merits. In all other cases, if a director, officer, employee, or agent acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, indemnification is discretionary except as otherwise provided by a corporation’s articles, code of regulations, or by contract except with respect to the advancement of expenses of directors.

Under Ohio law, a director is not liable for monetary damages unless it is proved by clear and convincing evidence that the director’s action or failure to act involved an act or omission undertaken with deliberate intent to cause injury to the corporation or undertaken with reckless disregard for the best interests of the corporation. There is, however, no comparable provision limiting the liability of officers, employees, or agents of a corporation. The statutory right to indemnification is not exclusive in Ohio, and Ohio corporations may, among other things, procure insurance for such persons.

The Fourth Amended and Restated Regulations of KeyCorp provide that KeyCorp shall indemnify to the fullest extent permitted by law any person made or threatened to be made a party to any action, suit, or proceeding by reason of the fact that he is or was a director, officer, or employee of KeyCorp or of any other bank, corporation, partnership, trust, or other enterprise for which he was serving as a director, officer, or employee at the request of KeyCorp.

II-1

Under the terms of KeyCorp’s directors’ and officers’ liability and company reimbursement insurance policy, directors and officers of KeyCorp are insured against certain liabilities, including liabilities arising under the Securities Act.

KeyCorp is party to Change of Control Agreements with certain executive officers pursuant to which KeyCorp has agreed to indemnify the officer, to the fullest extent permitted or authorized by Ohio law, if the officer is made or threatened to be made a party to any action, suit, or proceeding by reason of the officer’s serving as employee, officer, or director of KeyCorp and/or any of its subsidiaries, and KeyCorp has agreed to advance expenses incurred by the officer in defending any such action, suit, or proceeding.

Item 17.

Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (17 C.F.R. § 424(b)) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the registration statement is on Form S-3 (17 C.F.R. § 239.13) or Form F-3 (17 C.F.R. § 239.33) and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) (17 C.F.R. § 230.424(b)) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) (17 C.F.R. § 230.424(b)(3)) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) (17 C.F.R. § 230.424(b)(2), (b)(5), or (b)(7)) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) (17 C.F.R. § 230.415(a)(1)(i), (vii), or (x)) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated

II-3

by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(5) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
