• Icosavax stockholders to receive $15.00 per share in cash at closing plus non-tradeable contingent value right (CVR) of up to $5.00 per share 
  
• Representing a total equity value of up to $1.1 billion including the CVR 

SEATTLE, Dec. 11, 2023 (GLOBE NEWSWIRE) -- Icosavax, Inc. (Nasdaq: ICVX) today announced it has entered into a definitive agreement pursuant to which AstraZeneca, through an acquisition subsidiary, will initiate a tender offer to acquire all of Icosavax’s outstanding shares for a price of $15.00 per share in cash at closing, plus a non-tradable contingent value right to receive up to $5.00 in cash, payable upon achievement of specified regulatory and net sales milestones.

The upfront cash portion of the consideration represents an equity value of approximately $838 million and a 43% premium over Icosavax’s closing market price on December 11, 2023, and a 73% premium to Icosavax’s volume-weighted average price for the preceding 60 trading days. Combined, the upfront and maximum potential contingent value payments represent, if achieved, an equity value of approximately $1.1 billion and a 91% premium over Icosavax’s closing market price on December 11, 2023, and a 130% premium to Icosavax’s volume-weighted average price for the preceding 60 trading days.

The closing of the tender offer is subject to certain conditions, including the tender of shares representing at least a majority of the total number of Icosavax’s outstanding shares, and other customary closing conditions and regulatory clearances. Upon the successful completion of the tender offer, a subsidiary of AstraZeneca will be merged with and into Icosavax and any remaining shares of common stock of Icosavax will be cancelled and converted into the right to receive the same consideration (including the contingent value right) per share payable in the tender offer. Subject to the satisfaction of the conditions in the merger agreement, the acquisition is expected to close in the first quarter of 2024.

Adam Simpson, Chief Executive Officer, Icosavax, said, “We are pleased to announce the proposed acquisition of Icosavax by AstraZeneca as we believe it offers the opportunity to accelerate, and expand access to, our potential first-in-class combination vaccine for older adults at risk from RSV and hMPV. We look forward to combining our skills and expertise in advancing the development of IVX-A12, with AstraZeneca’s decades of experience in RSV, resources, and capabilities in late-stage development.”

Iskra Reic, Executive Vice President, Vaccines & Immune Therapies, AstraZeneca, said: “This virus-like particle vaccine technology has the potential to transform prevention against severe infectious diseases, including RSV and hMPV. With the addition of Icosavax’s Phase III-ready lead asset to our late-stage pipeline, we will have a differentiated, advanced investigational vaccine, and a platform for further development of combination vaccines against respiratory viruses. This aligns with our strategy to deliver a portfolio of therapies to address high unmet needs in infectious diseases, and our ambition to protect the most vulnerable patients who have high risk of severe outcomes.”

Concurrent with this press release, Icosavax issued a press release announcing positive topline interim results for Icosavax’s Phase 2 study of IVX-A12, a combination virus like particle (VLP) vaccine candidate targeting both respiratory syncytial virus (RSV) and human metapneumovirus (hMPV).
