bluebird bio Reminds Stockholders to Act Now to Tender Shares for Acquisition by Carlyle and SK Capital

SOMERVILLE, Mass.--(BUSINESS WIRE)-- bluebird bio, Inc. (NASDAQ: BLUE) (“bluebird” or “the Company”) today reminds all stockholders to promptly tender their shares into the tender offer by Carlyle and SK Capital to purchase all outstanding shares of bluebird common stock by 11:59 p.m. Eastern on May 29, 2025. Stockholders that hold shares of bluebird through a broker or other nominee may be subject to a processing cutoff that is prior to the tender deadline, so it is important to act now.

Additionally, the Company today announced that Ayrmid Ltd. (“Ayrmid”) has confirmed it will not submit a binding proposal to acquire bluebird following bluebird’s amended agreement with Carlyle and SK Capital. 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 or retender into the current agreement.

Every share tendered by stockholders is important and it is important to tender now. The Board continues to believe that the transaction with Carlyle and SK Capital, as amended, represents the only viable option for stockholders to receive consideration for their shares. Absent a majority of stockholders tendering, bluebird is at significant risk of defaulting on its loan agreements with Hercules Capital. It is extremely unlikely that stockholders would receive any consideration for their shares in a bankruptcy or liquidation.

Details on Amended Agreement with Carlyle and SK Capital

Under the terms of the amended agreement, bluebird stockholders can elect to receive either (x) the original offer of $3.00 per share in cash plus a contingent value right (“CVR”) of $6.84 per share in cash payable upon achievement of a net sales milestone or (y) $5.00 per share in cash. Any shares tendered for which no election is made will receive the original consideration of $3.00 per share in cash plus a CVR per share.

As previously announced on May 5, 2025, Carlyle and SK Capital have received all required regulatory approvals to complete the transaction, and all parties expect the transaction to be consummated promptly following the successful completion of the ongoing tender offer, which expires one minute after 11:59 p.m. New York City time on May 29, 2025.

Instructions for Stockholders

• Stockholders that have previously tendered their shares into the original agreement must re-tender their shares and complete and sign the letter of election and transmittal attached to the Offer to Purchase. Detailed instructions are available in the Offer to Purchase.
• Shares tendered prior to the amended agreement will not be valid unless they are re-tendered with an election. If stockholders that previously tendered do not take action, it will have the same effect as withdrawing previously tendered shares from the offer.
• Stockholders that hold shares of bluebird through a broker or other nominee may be subject to a processing cutoff that is prior to the tender deadline, so it is important to act now.
• Stockholders who need assistance with tendering their shares of bluebird may contact the Information Agent, Innisfree M&A Incorporated, by calling toll-free at (877) 825-8793.
