Fourth Quarter and Full Year 2025 Financial Results
Cash and cash equivalents as of December 31, 2025, were $146.6 million compared to $269.9 million as of December 31, 2024. The Company expects that the existing cash and cash equivalents will enable the Company to fund its operating expenses and capital expenditure requirements into the third quarter of 2027.

Fourth Quarter 2025

• For the three months ended December 31, 2025, net loss attributable to common stockholders was $5.6 million, or $0.06 per share, compared to net loss of $45.4 million, or $0.55 per share, for the same period in 2024.

• Collaboration and other research and development revenues decreased to $24.7 million for the three months ended December 31, 2025, compared to $30.6 million for the same period in 2024. The decrease is primarily attributable to the recognition of revenue related to milestones achieved under the Company’s collaboration agreement with BMS in the fourth quarter of 2024.

• Research and development expenses decreased by $21.2 million to $27.4 million for the three months ended December 31, 2025, compared to $48.6 million for the same period in 2024. The decrease is primarily related to reduced clinical and manufacturing costs related to discontinuation of the clinical development of the Company’s reni-cel program initiated in December 2024, partially offset by costs attributable to in vivo research and discovery.

• General and administrative expenses decreased by $5.0 million to $11.4 million for the three months ended December 31, 2025, compared to $16.4 million for the same period in 2024. The decrease is primarily attributable to a reduction in employee-related expenses related to reduced headcount associated with the reduction in workforce, as well as reduced professional services in connection with the discontinuation of the clinical development of the Company’s reni-cel program initiated in December 2024.

• Restructuring and impairment charges decreased by $18.5 million to a $6.3 million benefit for the three months ended December 31, 2025, compared to $12.2 million for the same period in 2024. The decrease is primarily attributable to favorable adjustments to prior estimated costs for contracts associated with the discontinuation of the clinical development of the Company’s reni-cel program upon finalization of contract costs.
  
  

Full Year 2025

• For the full year 2025, net loss attributable to common stockholders was $160.1 million, or $1.80 per share, compared to net loss of $237.1 million, or $2.88 per share, for the same period in 2024.

• Collaboration and other research and development revenues increased to $40.5 million for 2025, compared to $32.3 million for the same period in 2024. The increase was attributable to recognition of the remaining deferred revenue upon the conclusion of a collaboration agreement with a strategic partner, as well as recognition of revenue related to a milestone achieved in 2025 under our collaboration with BMS.

• Research and development expenses decreased by $109.2 million to $90.0 million for 2025, compared to $199.2 million for the same period in 2024. The decrease was primarily attributable to reduced clinical and manufacturing costs due to the discontinuation of the Company’s former reni-cel program, partially offset by costs attributable to in vivo research and discovery.

• General and administrative expenses decreased by $22.1 million to $49.9 million for 2025, compared to $72.0 million for the same period in 2024. The decrease was primarily related to reduced headcount associated with the workforce reduction and reduced professional services related to the discontinuation of the Company’s former reni-cel program.

• Restructuring and impairment charges increased by $48.4 million to $60.7 million for 2025, compared to $12.2 million for the same period in 2024. The increase was attributable actions associated with the discontinuation of the Company’s former reni-cel program and the associated workforce reduction.
  
  

About Heterozygous Familial Hypercholesterolemia (HeFH)
Heterozygous Familial Hypercholesterolemia (HeFH) is an inherited genetic disorder that leads to significantly elevated LDL?cholesterol levels from an early age. Individuals with HeFH are at high risk of heart disease, heart attack, or stroke if the condition is not identified and treated early. An estimated 1.2 million people in the United States are living with HeFH, though many remain undiagnosed. Elevated LDL-C, also known as hyperlipidemia, is a highly prevalent disease affecting over 70 million patients in the United States alone. Substantial unmet need exists across multiple at-risk segments of patients with hyperlipidemia, including the HeFH population.
