Bluebird's Surprise: Ayrmid's Premium Offer Shakes Up Existing Deal
Deal News | Mar 28, 2025 | EIN

Bluebird bio, a gene therapy company facing commercialization challenges, has received a superior acquisition bid from Ayrmid. This new offer is 50% higher than an existing deal struck with Carlyle and SK Capital Partners. Ayrmid proposes to buy bluebird for $4.5 per share upfront along with a one-time contingent value right of $6.84 per share linked to a sales milestone. The previously agreed offer with Carlyle-SK stood at $3 per share with a similar CVR. Bluebird's board is currently reviewing the Ayrmid proposal, adhering to fiduciary obligations while maintaining compliance with their pre-existing agreement's terms. If bluebird chooses Ayrmid’s offer, they will incur a $1.5 million termination fee, yet the higher offer more than compensates for this. Ayrmid’s bid significantly values bluebird at approximately $45 million, contrasting with Carlyle-SK's $29 million offer. Notably, Ayrmid had been approached by bluebird in the past for a takeover interest but declined to make a proposal at that time. Ayrmid is known to be the parent company of Gamida Cell, a cell therapy firm focusing on blood cancers.
