Sanofi to acquire Translate Bio; advances deployment of mRNA technology across vaccines and therapeutics development

• Accelerates development of current Sanofi licensed programs in vaccines and potential to explore other therapeutic areas
• Fast tracks establishment of Sanofi’s recently announced mRNA Center of Excellence
• Full integration upgrades drug formulation capabilities and enhances US talent in a promising new technology

PARIS and LEXINGTON, Mass – August 3, 2021 – As part of Sanofi’s endeavor to accelerate the application of messenger RNA (mRNA) to develop therapeutics and vaccines, the company has entered into a definitive agreement with Translate Bio (NASDAQ: TBIO), a clinical-stage mRNA therapeutics company, under which Sanofi will acquire all outstanding shares of Translate Bio for $38.00 per share in cash, which represents a total equity value of approximately $3.2 billion (on a fully diluted basis). The Sanofi and Translate Bio Boards of Directors unanimously approved the transaction.

“Translate Bio adds an mRNA technology platform and strong capabilities to our research, further advancing our ability to explore the promise of this technology to develop both best-in-class vaccines and therapeutics,” said Paul Hudson, Sanofi Chief Executive Officer. “A fully owned platform allows us to develop additional opportunities in the fast-evolving mRNA space. We will also be able to accelerate our existing partnered programs already under development. Our goal is to unlock the potential of mRNA in other strategic areas such as immunology, oncology, and rare diseases in addition to vaccines.”

“Sanofi and Translate Bio have a shared commitment to innovation in the mRNA space. With Sanofi’s long-standing expertise in developing and commercializing vaccines and other innovative medicines on a global scale, Translate Bio’s mRNA technology is now even better positioned to reach more people, faster,” said Ronald Renaud, Chief Executive Officer, Translate Bio. “The talented and dedicated Translate Bio team has built the foundation of a strong mRNA platform. Our expertise coupled with that of Sanofi has driven significant progress under the collaboration thus far, and we believe that this acquisition will strengthen the team’s ability to achieve the full potential of the mRNA technology.”

In June 2018, Sanofi and Translate Bio entered into a collaboration and exclusive license agreement to develop mRNA vaccines which was further expanded in 2020 to broadly address current and future infectious diseases. There are two ongoing mRNA vaccine clinical trials under the collaboration, the COVID-19 vaccine Phase 1/2 study with results expected in Q3 2021 and the mRNA seasonal influenza vaccine Phase 1 trial with results due in Q4 2021. The acquisition builds on Sanofi’s establishment of a first-of-its kind vaccines mRNA Center of Excellence.

On the therapeutic side, Translate Bio has an early-stage pipeline in cystic fibrosis and other rare pulmonary diseases. In addition, discovery work is ongoing in diseases that affect the liver, and Translate Bio’s MRT^TM platform may be applied to various classes of treatments, such as therapeutic antibodies or vaccines in areas such as oncology. Sanofi’s recent acquisition of Tidal Therapeutics expanded the company’s mRNA research capabilities in both immuno-oncology and inflammatory diseases. The Translate Bio acquisition further accelerates Sanofi’s efforts to develop transformative medicines using mRNA technology.

Transaction Terms

Under the terms of the merger agreement, Sanofi will commence a cash tender offer to acquire all outstanding shares of Translate Bio common stock for $38.00 per share in cash reflecting a total equity value of Translate Bio of approximately $3.2 billion. The purchase price represents a premium of 56% to Translate Bio’s volume-weighted average price per share over the past 60 days.

To demonstrate their commitment to the transaction, the chief executive officer of Translate Bio and Translate Bio’s largest shareholder, The Baupost Group, L.L.C., have signed binding commitments to support the tender offer. These binding commitments, combined with the Translate Bio shares already owned by Sanofi or its affiliates, represent a total of approximately 30% of Translate Bio’s total shares outstanding.

The consummation of the tender offer is subject to customary closing conditions, including the tender of a number of shares of Translate Bio common stock that together with shares already owned by Sanofi or its affiliates represents at least a majority of the outstanding shares of Translate Bio common stock, the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, and other customary conditions. Following the successful completion of the tender offer, a wholly owned subsidiary of Sanofi will merge with Translate Bio and the outstanding Translate Bio shares not already owned by Sanofi or its affiliates that are not tendered in the tender offer will be converted into the right to receive the same $38.00 per share in cash paid in the tender offer. The tender offer is expected to commence later this month. Sanofi plans to fund the transaction with available cash resources. Subject to the satisfaction or waiver of customary closing conditions, Sanofi expects to complete the acquisition in the third quarter of 2021.
