Carlyle, SK Capital Partners and bluebird bio Amend Merger Agreement
Stockholders may elect to receive either $3.00 per share plus CVR of $6.84 per share in cash payable upon achievement of a net sales milestone or $5.00 per share with no CVR
SOMERVILLE, Mass.—(BUSINESSWIRE)—May 14, 2025—bluebird bio, Inc. (NASDAQ: BLUE) (“bluebird”), Carlyle (NASDAQ: CG) (“Carlyle”) and SK Capital Partners, LP (“SK Capital”) today announced they have amended their definitive agreement pursuant to which Carlyle and SK Capital will purchase all of the outstanding shares of bluebird. 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. The amended offer price provides an alternative for stockholders who would prefer greater upfront cash consideration instead of the potential upside of the CVR. Any shares tendered for which no election is made will receive the original consideration of $3.00 per share in cash and a contingent value right per share.
The bluebird board of directors unanimously approved the amended agreement and recommends that all stockholders immediately tender their shares in support of the transaction. The bluebird board of directors 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, and it is extremely unlikely that stockholders would receive any consideration for their shares in a bankruptcy or liquidation.
In connection with the amended agreement, the expiration date of the tender offer has been extended to expire at one minute after 11:59 p.m., New York City time, on May 29, 2025. Equiniti Trust Company, LLC, the depositary for the Offer, has advised that as of the close of business on May 13, 2025, approximately 2,281,724 shares of bluebird common stock have been validly tendered and not properly withdrawn pursuant to the Offer.
Instructions for Stockholders:
- Stockholders that have previously tendered their shares and elect to receive the original offer of $3.00 per share plus a CVR do not need to re-tender their shares or take any other action in response to this extension
- Stockholders that have previously tendered their shares and wish to elect to receive $5.00 per share in cash must withdraw and 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.
- 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.
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.
