Item 7.01 Regulation FD Disclosure.

On May 18, 2026, Artivion, Inc. (“Artivion”) issued a press release announcing the completion of the acquisition of Endospan Ltd. (“Endospan”), an Israeli corporation that designs, develops, markets and sells innovative products for the treatment of aortic instability, including the Nexus™ product. A copy of the press release is furnished as Exhibit 99.1 hereto. Such press release shall not be deemed “filed” for purposes of Section 18 of the 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 made by Artivion under the Securities Act of 1933, as amended, or the Exchange Act.

Item 8.01 Other Events.

On May 18, 2026, Artivion completed its previously announced acquisition of Endospan pursuant to the exercise of Artivion’s option to purchase (directly or indirectly through an affiliate) all of the outstanding securities of Endospan. This transaction was consummated pursuant to that certain Securities Purchase Option Agreement, dated September 11, 2019, by and among Artivion, Endospan, the securityholders of Endospan listed in Schedule 1 thereto (together with any additional securityholder that becomes a party by joinder, the “Securityholders”), and Shareholder Representative Services LLC, as the Securityholder representative (as amended on July 1, 2024 and January 9, 2026, the “Agreement”).

As previously disclosed, the base purchase price of $175.0 million which, pursuant to the Agreement, Artivion elected to cause to be paid entirely in cash, was subject to certain adjustments for, among other things, working capital, indebtedness, cash and transaction expenses, as well as escrowed and reserved amounts for indemnification and purchase price adjustments, and outstanding indebtedness, including amounts outstanding under the Amended and Restated Loan Agreement, dated July 1, 2024, by and between Artivion and Endospan (the “Amended and Restated Loan Agreement”). CryoLife Asia Pacific Pte. Ltd., a private company limited by shares organized in Singapore and a wholly owned subsidiary of Artivion, paid a net purchase price, after offsetting the loans under the Amended and Restated Loan Agreement, of approximately $131.3 million. A portion of the purchase price was deposited into escrow accounts, including $16.5 million in an indemnity escrow fund and $1.0 million in an adjustment escrow fund, in each case subject to the terms and conditions of the Agreement.

In addition, the Securityholders are entitled to receive contingent consideration of up to $200.0 million based on the future performance of Endospan’s Nexus™ product, which amount, if any, would be determined and payable approximately two years following the closing of the acquisition.

The foregoing description of the acquisition and the Agreement does not purport to be complete and is subject to and qualified in its entirety by reference to the full text of the Securities Purchase Option Agreement, dated as of September 11, 2019, by and among Artivion, Endospan, the Securityholders and Shareholder Representative Services LLC, as the securityholder representative, Amendment No. 1 to Securities Purchase Option Agreement, dated July 1, 2024, by and among Artivion, Endospan and Shareholder Representative Services LLC, as the securityholder representative, and Amendment No. 2 to Securities Purchase Option Agreement, dated January 9, 2026, by and among Artivion, Endospan and Shareholder Representative Services LLC, as the securityholder representative, which were filed as Exhibits 10.1, 10.2 and 10.3, respectively, to the Current Report on Form 8-K filed by Artivion with the Securities Exchange Commission on May 7, 2026, and are incorporated by reference herein.

References to Nexus™ refer to Endospan’s NEXUS™ Aortic Arch Stent Graft System product. All brands, product names, company names, trademarks and service marks are the properties of their respective owners.
