Item 7.01.

Regulation FD Disclosure.

On March 9, 2026, Kalaris Therapeutics, Inc. (the “Company”) made available an updated corporate presentation that it plans to use for upcoming meetings with investors and analysts at The Leerink Partners Global Healthcare Conference and other conferences. The presentation includes updates regarding timelines for reporting data from the Company’s Phase 1b/2 multi-ascending dose clinical trial of TH103 and initiating Phase 3 clinical development of TH103, as well as other clinical operations updates and cash runway guidance.

A copy of the presentation is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

The information in this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and Section 21E of the Exchange Act, that involve substantial risk and uncertainties. All statements, other than statements of historical fact, contained in this Current Report on Form 8-K, including statements regarding timelines for reporting data from the Company’s Phase 1b/2 multi-ascending dose clinical trial of TH103 and initiating Phase 3 clinical development of TH103 and future expectations, plans and prospects for the Company, are forward-looking statements. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “would” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These statements are based on current expectations and beliefs of the management of the Company as well as assumptions made by, and information currently available to, the management of the Company and are subject to risks and uncertainties. There can be no assurance that future developments affecting the Company will be those that it has anticipated. Actual results or events could differ materially from the plans, intentions and expectations disclosed in these forward-looking statements as a result of various important factors, including: risks associated with the clinical development and regulatory approval of TH103, including potential delays in the completion of clinical trials; expectations regarding the therapeutic benefits, clinical potential and clinical development of TH103; the timing of and the Company’s ability to enroll patients in clinical trials; whether results from preclinical studies and initial data from early clinical trials will be predictive of the final results of the clinical trials or future trials; risks related to the inability of the Company to obtain sufficient additional capital to continue to advance its product candidate; uncertainties in obtaining successful clinical results for product candidates and unexpected costs that may result therefrom; risks related to the failure to realize any value from any product candidates being developed and anticipated to be developed in light of inherent risks and difficulties involved in successfully bringing product candidates to market; the ability to obtain, maintain, and protect intellectual property rights related to product candidates; changes in regulatory requirements and government incentives; the Company’s competitive position and expectations regarding developments and projections relating to its competitors and any competing therapies that are or become available; the risk of involvement in current and future litigation; and such other factors as are set forth in the Company’s public filings with the Securities and Exchange Commission, including, but not limited to, those described under the heading “Risk Factors”. The Company may not actually achieve the plans, intentions or expectations disclosed in its forward-looking statements, and you should not place undue reliance on its forward-looking statements. The forward-looking statements contained in this Current Report on Form 8-K are made as of the date of this Current Report on Form 8-K, and the Company does not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law.
