This Amendment No. 2 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission on June 10, 2026 (together with any subsequent amendments and supplements thereto, the “Schedule TO”), by Kuva Acquisition Corp., a Delaware corporation (“Purchaser”) and a direct wholly-owned subsidiary of Kuva Labs Inc., a Delaware corporation (“Parent”), and Parent. The Schedule TO relates to the offer by Purchaser to purchase all of the outstanding shares of common stock, par value $0.001 per share (the “Common Shares”), of Lisata Therapeutics, Inc., a Delaware corporation (the “Company”), at a purchase price of (i) $4.00 per Common Share, net to the seller in cash, without interest (the “Closing Amount”), plus (ii) one contingent value right (each, a “CVR”), which represents the contractual right to receive contingent cash payments of up to an aggregate of $3.00 per CVR subject to the achievement of the Milestones (as defined in the CVR Agreement), in accordance with the terms and subject to the conditions of a contingent value rights agreement (the “CVR Agreement”), net to the seller in cash, without interest (the Closing Amount plus one CVR, collectively, or any higher amount per Common Share paid pursuant to the Offer, the “Offer Price”) and less any applicable tax withholding, upon the terms and subject to the conditions set forth in the Offer to Purchase dated June 10, 2026 (together with any amendments or supplements thereto, the “Offer to Purchase”), and in the accompanying Letter of Transmittal, which are annexed to and filed with the Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively.

All information contained in the Offer to Purchase (including Schedule I to the Offer to Purchase) is hereby expressly incorporated by reference herein in response to Items 1 through 9 and Item 11 of this Schedule TO and is supplemented by the information specifically provided in this Amendment, except as otherwise set forth below. Except as otherwise set forth in this Amendment, the information in the Schedule TO remains unchanged and is incorporated herein by reference to the extent relevant to the items in this Amendment. Capitalized terms used but not defined herein have the meanings ascribed to them in the Schedule TO.

The Offer to Purchase and Items 1 through 9 and Item 11 of the Schedule TO, to the extent such Items incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented as set forth below. Page references below are to the Offer to Purchase as originally filed.

Section 10—“Background of the Offer; Past Contacts or Negotiations with the Company” of the Offer to Purchase is hereby amended and supplemented by adding the following paragraphs at the end thereof:

“On July 16, 2026, Purchaser, Parent, and the Company entered into an amendment to the Merger Agreement to extend the Outside Date from July 17, 2026 to July 21, 2026.”

The Offer to Purchase and the related Letter of Transmittal are hereby amended and supplemented to reflect that the Expiration Time of the Offer has been extended, as follows:

“On July 16, 2026, Purchaser extended the Expiration Time until 11:59 p.m., New York City time, on July 20, 2026, unless the Offer is further extended or earlier terminated as permitted by the Merger Agreement. The Offer was previously scheduled to expire at 11:59 p.m., New York City time, on July 16, 2026.

Equiniti Trust Company, LLC, the depositary for the Offer, has advised Purchaser that, as of 5:30 p.m., New York City time, on July 15, 2026, approximately 5,897,848 Common Shares have been validly tendered and not validly withdrawn pursuant to the Offer, representing approximately 64.67% of the 9,119,742 Common Shares outstanding as of July 15, 2026 (the most recent practicable date).

Parent and Purchaser expect the Offer will be consummated promptly following the expiration of the Offer (as hereby extended), subject to the satisfaction of the remaining conditions to the consummation of the Offer set forth in the Merger Agreement.”

Accordingly, all references to “11:59 p.m., New York City time, on July 16, 2026” set forth in the Offer to Purchase (Exhibit (a)(1)(A)), the Letter of Transmittal (Exhibit (a)(1)(B)), the Letter to Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees (Exhibit (a)(1)(C)), the Letter to Clients for use by Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees (Exhibit (a)(1)(D)) and the Form of Notice of Guaranteed Delivery (Exhibit (a)(1)(E)) are hereby amended and replaced with “11:59 p.m., New York City time, on July 20, 2026.”
