Item 1.01 Entry into a Material Definitive Agreement.

Agreement and Plan of Merger
 
On September 17, 2026, Lisata Therapeutics, Inc., a Delaware corporation (the “Company” or “Lisata”), acquired Marea Therapeutics, Inc., a Delaware corporation (“Marea”), in accordance with the terms of the Agreement and Plan of Merger, dated September 17, 2026 (the “Merger Agreement”), by and among the Company, Mariner Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“First Merger Sub”), Mariner Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Second Merger Sub”), and Marea. Pursuant to the Merger Agreement, First Merger Sub merged with and into Marea, pursuant to which Marea was the surviving corporation and became a wholly owned subsidiary of the Company (the “First Merger”). Immediately following the First Merger, Marea merged with and into Second Merger Sub, pursuant to which Second Merger Sub was the surviving entity (together with the First Merger, the “Merger”). The Merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes.
 
Under the terms of the Merger Agreement, upon the closing of the Merger (the “Closing”), the Company issued to the stockholders of Marea (i) 1,793,129.0 shares of the common stock of the Company, par value $0.001 per share (the “Common Stock”), and (ii) 211,365.213 shares of Series C Non-Voting Convertible Preferred Stock of the Company, par value $0.01 per share (the “Series C Preferred Stock”), each share of which is convertible into 1,000 shares of Common Stock, subject to approval by the stockholders of the Company of the Conversion Proposal (as defined below). The powers, preferences, rights, qualifications, limitations and restrictions applicable to the Series C Preferred Stock are set forth in the Certificate of Designation (as defined below).
 
Reference is made to the discussion of the Series C Preferred Stock in Item 5.03 of this Current Report on Form 8-K, which is incorporated into this Item 1.01 by reference.
 
Shares of Common Stock held by holders thereof immediately prior to the First Effective Time (as defined in the Merger Agreement) remain outstanding and were unaffected by the Merger. Immediately following the consummation of the Merger but prior to giving effect to the Financing (as defined below), assuming the conversion of shares of Series C Preferred Stock issued pursuant to the Merger Agreement into shares of Common Stock (without giving effect to any beneficial ownership limitations), pre-transaction equityholders of the Company held approximately 3.87% of the issued and outstanding shares of Common Stock and former equityholders of Marea held approximately 96.13% of the issued and outstanding shares of Common Stock, in each case, calculated on a fully-diluted basis and based on the implied equity values of the Company and Marea. Following the consummation of the Financing (as defined below), assuming the conversion of the PIPE Securities (as defined below) and shares of Series C Preferred Stock issued pursuant to the Merger Agreement into shares of Common Stock (in each case, without giving effect to any beneficial ownership limitations), pre-transaction stockholders of the Company hold approximately 2.39% of the issued and outstanding shares of Common Stock, former equityholders of Marea hold approximately 59.54% of the issued and outstanding shares of Common Stock and the Investors (as defined below) hold approximately 38.07% of the issued and outstanding shares of Common Stock, in each case, calculated on a fully-diluted basis and based on the implied equity values of the Company and Marea.
 
Pursuant to the terms of the Merger Agreement, each option to purchase Marea common stock was assumed by the Company and converted into an option to purchase Series C Preferred Stock (each, a “Parent Assumed Option”), which options are subject to exercise restrictions prior to obtaining the approval of the Parent Stockholder Matters (as defined below).
 
Pursuant to the Merger Agreement and the Purchase Agreement (as defined below), the Company has agreed to hold a stockholders’ meeting (the “Stockholders’ Meeting”) to submit the following matters to its stockholders for their consideration: (i) the approval of the conversion of the Series C Preferred Stock into shares of Common Stock in accordance with certain of the rules of the Nasdaq Stock Market LLC (the “Conversion Proposal”), (ii) the approval of a “change of control” under Nasdaq Listing Rules 5110 and 5635(b) (the “Change in Control Proposal”), (iii) to the extent deemed necessary or advisable by Company and/or Marea, the approval of an amendment to the certificate of incorporation of the Company to authorize sufficient shares of Common Stock for the conversion of the Series C Preferred Stock issued pursuant to the Merger Agreement and the Purchase Agreement (as described below) and/or to effectuate a reverse stock split of all outstanding shares of Common Stock at a reverse stock split ratio to be reasonably determined by the Company for the purpose of maintaining compliance with Nasdaq listing standards (the “Charter Amendment Proposal”), (iv) to the extent deemed necessary or advisable by the Company and/or Marea, the approval of (A) an equity incentive plan and (B) an employee stock purchase plan, in each case as approved by the Board (as defined below), and (v) such additional matters as may be mutually agreed between the Company and Marea to facilitate approval of the Conversion Proposal (the matters contemplated by clauses (i)–(v) collectively, the “Parent Stockholder Matters”). In connection with these matters, the Company intends to file with the Securities and Exchange Commission (the “SEC”) a proxy statement and other relevant materials. Holders of shares of Common Stock issued pursuant to the Merger Agreement and Parent Assumed Options (as defined in the Merger Agreement) will not be entitled to vote such shares in connection with the Conversion Proposal in accordance with Rule 5635 of the listing rules of Nasdaq and as provided in the Merger Agreement.
 
The Board of Directors of the Company (the “Board”) unanimously approved the Merger Agreement and the related transactions, and the consummation of the Merger did not require the approval of the Company stockholders.


The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.
 
The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the Company or Marea. The Merger Agreement contains representations, warranties and covenants that the Company and Marea made to each other as of specific dates. The assertions embodied in those representations, warranties and covenants were made solely for purposes of the Merger Agreement between the Company and Marea and may be subject to important qualifications and limitations agreed to by the Company and Marea in connection with negotiating its terms, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Merger Agreement. Moreover, the representations and warranties may be subject to a contractual standard of materiality that may be different from what may be viewed as material to investors or securityholders, or may have been used for the purpose of allocating risk between the Company and Marea rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures. For the foregoing reasons, no person should rely on the representations and warranties as statements of factual information at the time they were made or otherwise.

Marea Stockholders Registration Rights Agreement

In connection with the execution of the Merger Agreement, the Company entered into a Registration Rights Agreement (the “Marea Stockholders Registration Rights Agreement”) pursuant to which as promptly as practicable following the date of the Closing (and in any event not later than the later of (i) 45 days following the Financing Closing Date (as defined below) and (ii) the date upon which the Company shall have filed a current report on Form 8-K/A containing the financial statements of Marea and pro forma financial information required to be filed with the SEC in connection with the Merger (which Form 8-K/A shall be filed in any event no later than November 12, 2026) (such date in clause (ii), the “Form 8-K/A Filing Date”)), the Company has agreed to prepare and file with the SEC a Registration Statement on Form S-3 (or, if Form S-3 is not then available to the Company, on such form of registration statement as is then available) to register the resale of (i) the shares of Common Stock issued pursuant to the Merger Agreement and (ii) the shares of Common Stock underlying the Series C Preferred Stock issued pursuant to the Merger Agreement.
 
The foregoing summary of the Marea Stockholders Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Marea Stockholders Registration Rights Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Support Agreements

In connection with the execution of the Merger Agreement, the Company and Marea entered into stockholder support agreements (the “Support Agreements”) with the Company’s officers and directors (together with affiliated entities), solely in their capacity as stockholders of the Company, and representing approximately 4.3% of the pre-transaction shares of Common Stock outstanding. The Support Agreements provide that, among other things, each of the parties thereto has agreed to vote or cause to be voted all of the shares of Common Stock owned by such stockholder in favor of the Parent Stockholder Matters at the Stockholders’ Meeting to be held in connection therewith, subject to and in accordance with the terms of the Support Agreements.
 
The foregoing description of the Support Agreements does not purport to be complete and is qualified in its entirety by reference to the form of the Support Agreement, which is provided as Exhibit E to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Lock-up Agreements

Concurrently and in connection with the execution of the Merger Agreement, certain officers, directors and stockholders of Marea as of immediately prior to the Merger, and the Company’s directors and officers (together with affiliated entities) as of immediately prior to the Merger entered into lock-up agreements (the “Lock-up Agreements”) with the Company and Marea, pursuant to which each such stockholder will be subject to a 180-day lockup on the sale or transfer of shares of Common Stock, Series C Preferred Stock and any securities convertible into Common Stock held by each such stockholder at the Closing, including those shares received by Marea stockholders in the Merger.
 
The foregoing description of the Lock-up Agreements does not purport to be complete and is qualified in its entirety by reference to the form of the Lock-up Agreement, which is provided as Exhibit B to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Private Placement and Securities Purchase Agreement
 
On September 17, 2026, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with the purchasers named therein (the “Investors”).
 
Pursuant to the Purchase Agreement, the Company agreed to sell an aggregate of 150,867.995 shares of Series C Preferred Stock (the “PIPE Securities”) for an aggregate purchase price of approximately $225 million (the “Financing”). Each share of Series C Preferred Stock is convertible into 1,000 shares of Common Stock, as described below. The powers, preferences, rights, qualifications, limitations and restrictions applicable to the Series C Preferred Stock are set forth in the Certificate of Designation (as defined below).
 

The closing of the Financing is expected to occur on September 18, 2026 (the “Financing Closing Date”), subject to the satisfaction of customary conditions to closing.

The Financing is exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), as a transaction by an issuer not involving a public offering.

The Company shall use its commercially reasonable efforts to cause this registration statement to be declared effective by the SEC within five business days of the date the Company is notified by the SEC that the registration statement will not be reviewed (or within 60 calendar days if the SEC reviews the registration statement).
 
The Company has also agreed to, among other things, indemnify the Investors, their officers, directors, members, employees, partners, managers, stockholders, affiliates, investment advisors and agents under the registration statement from certain liabilities and pay all fees and expenses (excluding any legal fees of the selling holder(s), and any underwriting discounts and selling commissions) incident to the Company’s obligations under the Registration Rights Agreement.

Item 5.03 – Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.
 
On September 17, 2026, the Company filed with the Secretary of State of the State of Delaware a Certificate of Designation of Preferences, Rights and Limitations of the Series C Preferred Stock (the “Certificate of Designation”) in connection with the Merger and the Financing referenced in Item 1.01 above. The Certificate of Designation provides for the issuance of shares of the Company’s Series C Preferred Stock.
 
Holders of Series C Preferred Stock are entitled to receive dividends on shares of Series C Preferred Stock, equal to, on an as-if-converted-to-Common-Stock basis, and in the same form as dividends actually paid on shares of the Common Stock. Except as otherwise required by law, the Series C Preferred Stock does not have voting rights. However, as long as any shares of Series C Preferred Stock are outstanding, the Company will not, without the affirmative vote of the holders of a majority of the then outstanding shares of Series C Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series C Preferred Stock, (b) alter or amend the Certificate of Designation, (c) amend its certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series C Preferred Stock, (d) issue additional shares of Series C Preferred Stock or increase or decrease (other than by conversion) the number of authorized shares of Series C Preferred Stock, (e) prior to the automatic conversion of the Series C Preferred Stock, consummate a Fundamental Transaction (as defined in the Certificate of Designation) or a Change of Control Transaction (as defined in the Certificate of Designation), (f) prior to the automatic conversion of the Series C Preferred Stock, authorize or issue any class or series of stock that is senior to the Series C Preferred Stock, (g) amend, waive or modify the Merger Agreement in a manner that would be reasonably likely to prevent, impede or materially delay the obtainment of stockholder approval of the Conversion Proposal or the automatic conversion of the Series C Preferred Stock or (h) enter into any agreement with respect to any of the foregoing. The Series C Preferred Stock ranks senior to the Common Stock upon any liquidation, dissolution or winding-up of the Company solely to the extent of a nominal liquidation amount of $0.01 per share, and on parity with the Common Stock in all other respects.
 
Following stockholder approval of the Conversion Proposal, each share of Series C Preferred Stock will automatically convert into 1,000 shares of Common Stock, subject to certain limitations, including that a holder of Series C Preferred Stock is prohibited from converting shares of Series C Preferred Stock into shares of Common Stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than a specified percentage (to be established by the holder between 4.99% and 19.99%, with a default of 9.99%) of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such conversion.
 
If at any time after the earlier of (i) the Stockholder Approval or (ii) six months after the initial issuance of the Series C Preferred Stock, the Company fails to deliver to the holder of the Series C Preferred Stock shares of Common Stock underlying such shares of Series C Preferred Stock, then (other than in certain circumstances set forth in the Certificate of Designation), the Company will pay, at the request of such holder, an amount of cash by wire transfer of immediately available funds equal to the Fair Value (as defined in the Certificate of Designation) of such undelivered shares, provided that the Company has funds legally available for such payment.
 
The foregoing description of the Series C Preferred Stock does not purport to be complete and is qualified in its entirety by reference to the Certificate of Designation, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 7.01 – Regulation FD Disclosure.
