Carlyle and SK Capital Receive All Required Regulatory Approvals to Complete the Acquisition of bluebird bio

bluebird Board of Directors unanimously supports the transaction as the only viable option for stockholders to receive consideration for their shares and recommends that all stockholders immediately tender their shares into the offer

Parties expect the merger to be completed promptly following the successful completion of the ongoing tender offer

bluebird bio, Inc. (NASDAQ:BLUE) ("bluebird" or "the Company"), Carlyle (NASDAQ:CG) ("Carlyle"), SK Capital Partners, LP ("SK Capital") and Beacon Parent Holdings, L.P. ("Parent") announced today that all required regulatory approvals to complete the previously announced acquisition of the Company by Carlyle and SK Capital have been received.

No further regulatory approvals are required to complete the transaction. The parties expect to complete the merger promptly following the successful completion of the ongoing tender offer, which is scheduled to expire one minute after 11:59 p.m. New York City time on May 12, 2025, unless the tender offer is further extended or earlier terminated.

Under the terms of the merger agreement, stockholders will receive an upfront payment of $3.00 per share in cash and a contingent value right (CVR) of $6.84 per share in cash payable upon achievement of a net sales milestone, for a total potential value of $9.84 per share. The bluebird board of directors (the "Board") unanimously recommends that stockholders tender into the offer.

"The bluebird Board unanimously recommends that stockholders tender into the offer, which expires May 12, 2025. Absent a majority of stockholders tendering, bluebird is at significant risk of defaulting on its loan agreements with Hercules Capital and it is extremely unlikely that stockholders would receive any consideration for their shares in a bankruptcy or liquidation," said Mark Vachon, chairman of the bluebird bio Board of Directors. "The bluebird Board considered all reasonable alternatives during its review of strategic alternatives and concluded that the proposed transaction with Carlyle and SK Capital is the only viable solution to generate value for bluebird stockholders. We strongly urge stockholders to tender their shares before the expiration date to ensure the best possible outcome for all bluebird stakeholders and the patients that depend on its treatments."

"The receipt of all required regulatory approvals is excellent news for stockholders as well as for patients and families seeking to be treated with bluebird gene therapies," said Andrew Obenshain, chief executive officer, bluebird bio. "With this update, we have a clear path forward to close the transaction and officially begin the next chapter of bluebird's journey to deliver potentially curative gene therapies in the commercial setting."
