Item 1.01 Entry Into a Material Definitive Agreement.

 

On June 26, 2026, Arcturus Therapeutics, Inc. (“Arcturus”), a wholly-owned subsidiary of Arcturus Therapeutics Holdings Inc., a Delaware corporation (the “Company”), entered into a series of agreements with Thermo Fisher Scientific Inc. (“Thermo Fisher”) and certain of Thermo Fisher’s affiliates to establish a strategic collaboration for the provision of contract development and manufacturing organization (“CDMO”) and contract research organization (“CRO”) services in connection with the development of ARCT-032, the Company’s investigational mRNA therapeutic for cystic fibrosis (“CF”). The collaboration is structured through (i) a Master Services Agreement (the “MSA”) between Thermo Fisher and Arcturus and (ii) a Project Addendum for Development Services between Patheon UK Limited, a Thermo Fisher affiliate (“Patheon”), and Arcturus (the “Project Agreement”, and together with the MSA, the “Transaction Documents”).

 

Master Services Agreement

 

The MSA establishes the framework under which Thermo Fisher and its affiliates will provide CRO and CDMO services to Arcturus from time to time pursuant to the Project Agreement and any additional individual project addendums. CRO services will be provided through PPD, Inc., Thermo Fisher’s affiliated contract research organization (“PPD”), and CDMO services will be provided through Thermo Fisher’s Pharma Services division. Under the MSA, Thermo Fisher will contribute up to $40 million of clinical manufacturing services for ARCT-032, and Arcturus will engage PPD for up to $40 million in CRO services. Upon regulatory approval of ARCT-032, Thermo Fisher would receive exclusive commercial manufacturing rights for the product for a specified duration, on terms to be set forth in a definitive commercial supply agreement to be negotiated in good faith by the parties. Arcturus may engage an alternative manufacturer only if Thermo Fisher is unable to supply, limited solely to the quantities and duration necessary to address the supply shortfall. The MSA has an initial term of five years from the effective date and automatically renews for successive one-year periods unless either party provides at least 90 days’ prior written notice of non-renewal.

 

Project Agreement

 

Under the Project Agreement, the services to be provided include technical transfer, engineering batches, manufacture of clinical trial materials, manufacture of process performance qualification batches, open-label extension batches, drug product fill and finish, product release, and stability studies. The Project Agreement remains in effect from its effective date until the completion of all services or earlier termination under the MSA.

 

The foregoing descriptions of the MSA and the Project Agreement, do not purport to be complete and are qualified in their entirety by reference to the full text of each such agreement, copies of which the Company intends to file with the Securities and Exchange Commission (the “SEC”) as exhibits to the Company’s Quarterly Report on Form 10-Q for the quarter ending June 30, 2026.

 

Item 7.01 Regulation FD Disclosure.

 

On July 2, 2026, the Company issued a press release announcing the transactions described herein (the “Press Release”). A copy of the Press Release is furnished herewith as Exhibit 99.1.

 

The information set forth in this Item 7.01 of this Current Report on Form 8-K, including the Press Release, shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liability of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended. In addition, this information shall not be deemed incorporated by reference into any of the Company’s filings with the SEC, except as shall be expressly set forth by specific reference in any such filing.
