bluebird bio confirms that Ayrmid, Ltd. has not delivered a binding offer or obtained necessary financing despite extensive engagement

bluebird Board reaffirms unanimous recommendation in support of transaction with Carlyle and SK Capital and recommends all stockholders tender into the current agreement by May 2, 2025

bluebird bio, Inc. (NASDAQ: BLUE) (“bluebird” or “the Company”) today announced that after three weeks of engagement, including a timeline extension, Ayrmid Ltd. (“Ayrmid”) has not submitted a binding proposal to acquire bluebird and has not obtained necessary financing. In consultation with its financial and legal advisors, the bluebird Board of Directors (the “Board”) reaffirms its recommendation in support of the transaction with Carlyle and SK Capital and recommends all stockholders tender into the current agreement by May 2, 2025.

“Ayrmid’s proposal remains highly conditional, despite an extension to the previously agreed-upon timeline to complete confirmatory diligence and submit a binding offer,” said Mark Vachon, chairman of the bluebird bio Board of Directors. “bluebird has engaged with Ayrmid on two separate occasions—neither of which has resulted in a binding or fully-financed offer. After careful consideration with our financial and legal advisors, discussions with Hercules Capital, and taking into account that absent a significant infusion of capital, bluebird continues to be at significant risk of defaulting on its loan covenants, the Board unanimously reaffirms its support of the previously announced agreement with Carlyle and SK Capital in the strongest possible terms.”

Background on the Board’s Recommendation

As announced on February 21, 2025, bluebird entered into a definitive agreement (the “Merger Agreement”) with funds managed by global investment firms Carlyle and SK Capital, LP to be acquired and taken private for $3.00 per share in cash and a one-time contingent value right of $6.84 per share payable upon achievement of a net sales milestone, contingent upon certain offer conditions. The Board unanimously approved the agreement following a comprehensive review of bluebird’s strategic alternatives that included meeting with more than 100 potential investors and partners over a period of five months, and a third and final denial by the Federal Drug Administration of bluebird’s appeal for a priority review voucher.

After commencing the tender offer with Carlyle and SK Capital, bluebird subsequently received an unsolicited non-binding written proposal from Ayrmid to acquire bluebird for an upfront cash payment of $4.50 per share and a one-time contingent value right of $6.84 per share payable upon achievement of a net sales milestone. The Ayrmid Proposal was subject to significant conditions and further negotiations between the parties, including confirmatory diligence.

Consistent with its fiduciary duties, bluebird and the Board agreed to a two-week period of confirmatory diligence with Ayrmid to conclude with submission of a binding offer ready for signature. On April 11, 2025, at the request of Ayrmid, bluebird agreed to extend this period by four additional days. Ayrmid did not deliver a binding offer at the conclusion of that period and also acknowledged that it had not obtained necessary financing for its proposal. Ayrmid indicated they are continuing to pursue financing and expected to provide an update in the coming week. In addition to the most recent three-week diligence period Ayrmid was also party to the strategic process prior to announcement of the agreement with Carlye and SK Capital. In light of Ayrmid’s failure to deliver a binding offer after three weeks of engagement, or as part of the earlier strategic review process, the Board reiterates its unanimous recommendation in support of the transaction with Carlyle and SK Capital. In making this determination, the Board considered that absent a significant infusion of capital, bluebird continues to be at significant risk of defaulting on its loan covenants and the transaction with Carlyle and SK Capital Partners is the only currently viable solution to generate value for stockholders.
