"Notably this quarter, we secured additional capital through the close of a private financing and completion of the sale of our manufacturing facility in North Carolina and continued to make meaningful progress with our product pipeline, including filing the US biologics licensing application for beti-cel for beta-thalassemia. I am excited for what lies ahead for both bluebird and 2seventy bio, and the impact that both companies will have for patients and their families."

THIRD QUARTER 2021 FINANCIAL RESULTS

• Cash Position: Cash, cash equivalents and marketable securities as of September 30, 2021, and December 31, 2020, were $970.7 million and $1.27 billion, respectively. The decrease in cash, cash equivalents and marketable securities is primarily related to cash used in support of ordinary course operating activities.
• Revenues: Total revenues were $22.7 million for the three months ended September 30, 2021, compared to $19.3 million for the three months ended September 30, 2020. Total revenues were $42.9 million for the nine months ended September 30, 2021, compared to $240.0 million for the nine months ended September 30, 2020. The increase for the three-month period was primarily driven by our collaborative arrangement revenue recognized under our collaboration arrangement with BMS. The decrease for the nine-month period was primarily driven by a cumulative catch-up adjustment to revenue recorded in connection with the May 2020 BMS contract modification in the second quarter of 2020.
• ABECMA Revenue: This quarter Bristol-Myers Squibb (BMS) reported total U.S. revenues of $67 million for ABECMA (idecabtagene vicleucel; ide-cel). bluebird bio reported a net collaboration revenue of $14.8 million for 3Q, which includes the company's share of revenue and costs associated with the commercialization of ABECMA in the U.S.
• R&D Expenses: Research and development expenses were $131.4 million for the three months ended September 30, 2021, compared to $140.4 million for the three months ended September 30, 2020. Research and development expenses were $429.6 million for the nine months ended September 30, 2021, compared to $450.9 million for the nine months ended September 30, 2020. The decrease for the three-month period was primarily driven by decreased collaboration research funding costs resulting from a decrease in expense recognized under our collaboration arrangement with BMS. The decrease for the nine-month period was primarily driven by decreased manufacturing expenses.
• SG&A Expenses: Selling, general and administrative expenses were $68.3 million for the three months ended September 30, 2021, compared to $68.0 million for the three months ended September 30, 2020. Selling, general and administrative expenses were $229.7 million for the nine months ended September 30, 2021, compared to $210.0 million for the nine months ended September 30, 2020. The increase for both periods was primarily driven by an increase in fees associated with the spinoff of 2seventy bio as well as increased employee compensation, benefit, and other headcount related expenses.
• Restructuring Expenses: Restructuring expenses were $20.2 million and $24.8 million for the three months and nine months ended September 30, 2021, respectively. These costs are related to a reduction in the workforce, primarily driven by the wind down of operations in Europe.
• Net Loss: Net loss was $216.8 million for the three months ended September 30, 2021, compared to $194.7 million for the three months ended September 30, 2020.
