SECOND QUARTER FINANCIAL HIGHLIGHTS

• Cash Position: The Company’s cash, cash equivalents and restricted cash balance was approximately $193 million, including restricted cash of approximately $49 million, as of June 30, 2024.
  
  Based on current operating assumptions, bluebird expects its cash and cash equivalents as of June 30, 2024 will be sufficient to fund its operations into the second quarter of 2025ⁱ, not accounting for the cash minimums required under the Company’s loan agreement with Hercules Capital, Inc. and excluding receipt of any future tranches under the agreement.
  
  The Company has also renegotiated certain terms of its loan agreement with Hercules Capital, Inc. and is eligible to receive two future tranches totaling $50 million, contingent upon achievement of patient start and product delivery milestones and completion of additional financing. These tranches take the place of previously agreed tranches tied to patient starts and gross profit.

• Revenue, net: Total revenue, net was $16.1 million for the three months ended June 30, 2024, compared to $6.9 million for the three months ended June 30, 2023. The increase of $9.2 million was due to increased ZYNTEGLO product revenue.

On March 26, 2024, bluebird announced that it will restate its consolidated financial statements as of and for the year ended December 31, 2022, and for each of the first three quarters of 2022 and 2023 in its Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K"). The restatements relate to the identification of leases and the treatment of non-lease components contained in lease agreements. The restatement is not expected to impact the Company’s cash position or revenue. As a result of the restatement, the Company is delayed in filing its 2023 Form 10-K and its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2024 (the “Q1 2024 Form 10-Q") and June 30, 2024 (the “Q2 2024 Form 10-Q”). The Company is continuing to work expeditiously to complete these filings.

The financial results included in this press release represent the most current information available to the Company’s management.
