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.

transactions described herein (the “Press Release”). A copy of the Press Release is furnished herewith as Exhibit 99.1.

Arcturus Therapeutics

Strategic manufacturing agreement includes Phase
3 clinical supply and commercial manufacturing rights
SAN DIEGO, Calif. --(BUSINESS WIRE)--July 2, 2026--Arcturus
Therapeutics Holdings Inc. (“Arcturus”, Nasdaq: ARCT), a messenger RNA medicines company focused on the development of
liver and respiratory rare disease therapeutics, today announced a strategic collaboration with Thermo Fisher Scientific, the world
leader in serving science, to help support the Phase 3 development and potential commercialization of ARCT-032, Arcturus’ investigational

The collaboration will leverage Thermo Fisher's
Accelerator™ Drug Development solutions, combining manufacturing and clinical research capabilities to support Phase 3 development
through potential commercialization. Thermo Fisher will provide integrated manufacturing, clinical research, and commercial readiness
services to help accelerate development of ARCT-032 while Arcturus continues to advance the program.
“We are pleased to collaborate with Thermo
Fisher to utilize its impressive CDMO capabilities, global infrastructure, and proven ability to support complex mRNA programs from Phase
3 through potential commercialization,” said Joseph Payne, President and Chief Executive Officer of Arcturus Therapeutics. “Their
capabilities are aligned with Arcturus’ goal of efficiently advancing our cystic fibrosis program into Phase 3 and preparing for
potential commercial supply.”
“Biotechnology innovators increasingly seek
strategic collaborators that can support complex development programs across clinical and commercial stages,” said Mike Shafer,
Executive Vice President and President, Biopharma Services, Thermo Fisher Scientific. “Through Accelerator™ Drug Development,
Thermo Fisher brings together manufacturing, clinical research, and commercialization expertise to help customers simplify development,
reduce operational complexity, and accelerate the delivery of innovative therapies to patients. Our collaboration with Arcturus demonstrates
the value of this integrated model.”
Under the agreement,
Thermo Fisher will provide Phase 3 manufacturing, clinical research, and related services. If Phase 2 yields positive results, Arcturus
expects to conduct its Phase 3 program through Thermo Fisher's PPD™ clinical research business. Subject to regulatory approval of
ARCT-032, Thermo Fisher will receive exclusive commercial manufacturing rights under a separate commercial agreement.
