Item 5.07			Submission of Matters to a Vote of Security Holders.

As previously reported, bluebird bio, Inc. (the “Company”) held its Annual Meeting of Stockholders (the “Annual Meeting”) on November 6, 2024 at which a quorum was present. As reported on the Company’s Current Report on Form 8-K filed on November 6, 2024, the Annual Meeting was adjourned until December 4, 2024 to allow the Company to solicit additional proxies to approve amendments to the Certificate of Incorporation to effect a reverse stock split of the Company’s common stock at a ratio ranging from any whole number between 1-for-15 and 1-for-20, as determined by the Board in its discretion (“Proposal 4”).

On December 4, 2024, the Company reconvened the Annual Meeting and the sole item of business presented to its stockholders for consideration was a vote on Proposal 4, which was approved by the requisite vote of the Company’s stockholders. The final voting results for Proposal 4 are set forth below:


Votes For	Votes Against	Abstentions	Broker Non-Votes
99,839,224	34,711,232	675,466	0


Item 8.01			Other Events.

As disclosed above, at the Annual Meeting, the stockholders of the Company approved a reverse stock split of all outstanding shares of the Company’s common stock, at a ratio ranging from any whole number between 1-for-15 and 1-for-20, with the exact ratio as determined by the Board in its discretion. On December 4, 2024, the Board approved a reverse stock split of the Company’s common stock at a final ratio of 1-for-20 (the “Reverse Stock Split”) and abandoned all other amendments. The Reverse Stock Split is expected to become effective at 5:00 p.m. Eastern Time on December 12, 2024, following the filing of a certificate of amendment with the Secretary of State of the State of Delaware, in substantially the form described and set forth in our Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on September 26, 2024 under Proposal 4 and Appendix B. The common stock is expected to commence trading on a split-adjusted basis when the markets open on December 13, 2024, under the existing trading symbol “BLUE.” The new CUSIP number for the common stock following the Reverse Stock Split will be 09609G 209.

No fractional shares will be issued if, as a result of the Reverse Stock Split, a stockholder would otherwise become entitled to a fractional share because the number of shares of common stock they hold before the Reverse Stock Split is not evenly divisible by the split ratio. Instead, each stockholder will be entitled to receive a cash payment in lieu of such fractional share. The cash payment to be paid will be equal to the fraction of a share to which such stockholder would otherwise be entitled multiplied by the closing price per share as reported by The Nasdaq Global Select Market (as adjusted to give effect to the Reverse Stock Split) on December 12, 2024.
