Sanofi agrees to buy mRNA partner Translate Bio in $3.2 bn deal

Bid for Translate Bio marks latest interest by large pharmaceutical firm in mRNA tech

Sanofi has agreed to buy US biotech company Translate Bio in a $3.2 billion (€2.69bn) deal, as it bets on next-generation mRNA vaccine technology beyond the Covid-19 pandemic.

Sanofi said it would acquire all outstanding shares of Translate Bio for $38.00 per share in cash, representing a total equity value of about $3.2 billion.

The boards of both companies have approved the deal. And the chief executive of Translate Bio and the US company’s largest shareholder have backed it, said Sanofi and Translate Bio in a joint statement.

Shares in the French pharmaceuticals company edged up 0.3 per cent in early morning trade.


"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 Sanofi chief executive Paul Hudson.

Sanofi’s offer of $38 represented a 30.4 per cent premium on the New York-listed company’s August 2nd closing share price.

Translate Bio’s stock soared more than 70 per cent to above $50 in extended trading on Monday following the Reuters report.


Sanofi's bid for Translate Bio marks the latest interest by a large pharmaceutical company in mRNA technology, following its proven success in Covid-19 vaccines developed by Pfizer-BioNTech and Moderna.

Analysts said the price made strategic sense, a long-term wager on mRNA vaccine technology beyond Covid-19 by one of the world’s top flu vaccine makers.

“Since Covid, mRNA vaccines have made a big impact on the future of vaccine R&D and the most obvious target for next generation mRNA vaccines is influenza,” Liberum wrote in a briefing note.

The messenger RNA (ribonucleic acid) approach, an area of Translate Bio expertise, instructs human cells to make specific proteins that produce an immune response to a given disease.

Sanofi and Translate Bio joined forces last year to develop an mRNA-based Covid-19 vaccine. They expect interim results of their Phase I/II clinical trial in the third quarter.

The two companies are also looking at mRNA vaccines for several infectious diseases and in June started a Phase I trial evaluating a possible mRNA-based vaccine against seasonal flu.

Rival Moderna launched a Phase I/II trial into a possible mRNA flu shot in July.

Tough year

Sanofi expects to complete the acquisition in the third quarter of 2021.

Translate Bio's chief executive and its largest shareholder, Baupost Group, signed binding commitments to support the deal. Their shares combined with those already held by Sanofi represent about 30 per cent of Translate Bio's total shares outstanding.

Sanofi’s interest comes after a tough year for the French drug maker after falling behind rivals in the Covid-19 vaccine race, a major blow to Mr Hudson who joined the company almost two years ago.

Sanofi warned last year its traditional, protein-based Covid-19 jab developed with GlaxoSmithKline showed an insufficient immune response in older people, delaying its launch until toward the end of 2021.

Mr Hudson has also been under increasing pressure to reduce the company’s dependence on its star eczema treatment Dupixent to boost earnings.

Earlier this year, Sanofi agreed to fill and pack millions of doses of shots made by Pfizer-BioNTech, Johnson & Johnson and Moderna.

Translate Bio, set up in 2016, has not launched any drugs on the market but its clinical-stage pulmonary product using its mRNA platform is being tested as an inhaled treatment for cystic fibrosis in a Phase I/II clinical trial. – Reuters
