Second Quarter 2023 Financial Results

Cash, cash equivalents, and marketable securities as of June 30, 2023, were $480.0 million compared to $401.8 million as of March 31, 2023.

For the three months ended June 30, 2023, net loss attributable to common stockholders was $40.3 million, or $0.56 per share, compared to net loss of $53.5 million, or $0.78 per share, for the same period in 2022.
Collaboration and other research and development revenues decreased by $3.5 million to $2.9 million for the three months ended June 30, 2023, compared to $6.4 million for the same period in 2022. The decrease is related to Bristol Myers Squibb's program opt-in in the second quarter of 2022 that did not occur in the same period of 2023.
Research and development expenses decreased to $29.8 million for the three months ended June 30, 2023, compared to $43.7 million for the same period in 2022. The $13.9 million decrease is attributable to the Company's strategic reprioritization, including a targeted clinical and manufacturing focus on EDIT-301, and reduced employee-related costs.
General and administrative expenses remained relatively flat, slightly increasing by $0.3 million to $17.2 million for the three months ended June 30, 2023, from $16.9 million for the same period in 2022.
