Additionally, we announced that our workforce was reduced by 47 employees, or approximately 32 % of our workforce.
−Removed: As a result, we recorded cash severance costs, benefits, and transition support services expenses of $ 1.8 million for each of the three- and six-month periods ended June 30, 2025, which we recorded as research and development expenses or general and administrative expenses in our unaudited condensed consolidated statements of operations and comprehensive loss.
−Removed: For each of the three- and six-month periods ended June 30, 2025, we recorded wind down costs of $ 0.3 million as research and development expenses in our unaudited condensed consolidated statements of operations and comprehensive loss related to the discontinuation of our GALLOP phase 1 clinical trial and AMpLify phase 1 clinical trial.
+Added: As a result, we recorded cash severance costs, benefits, and transition support services expenses of $ 1.8 million for the nine months ended September 30, 2025, which we recorded as research and development expenses or general and administrative expenses in our unaudited condensed consolidated statements of operations and comprehensive loss.
+Added: For the nine months ended September 30, 2025, we recorded wind down costs of $ 0.4 million, as research and development expenses in our unaudited condensed consolidated statements of operations and comprehensive loss related to the discontinuation of our GALLOP and AMpLify phase 1 clinical trials.
Impairment Charges
As part of the preparation of the financial statements for each reporting period, we review our long-lived assets for impairment indicators.
−Removed: As a result of the previously announced strategic pipeline prioritization, we identified certain triggering events, such as significant changes in our current and expected use of leased office and lab space, and lab equipment.
−Removed: We determined the asset groups based on the lowest level of identifiable cash flows under the our strategic pipeline prioritization and assessed the impairment for each of the asset groups.
+Added: As a result of the previously announced strategic pipeline prioritization during the second quarter of 2025, we identified certain triggering events, such as significant changes in our current and expected use of leased office and lab space, and lab equipment.
+Added: We determined the asset groups based on the lowest level of identifiable cash flows under our strategic pipeline prioritization and assessed the impairment for each of the asset groups.
We have reduced the usage of our leased office and lab space, and we may sublease the unused space.
The leasehold improvements, right of use assets, and lab equipment related to the leased office and lab space were assessed as a single asset group and determined to not be recoverable.
−Removed: Accordingly, in connection with the preparation of the financial statements for the three and six months ended June 30, 2025, we concluded that this asset group is impaired.
+Added: Accordingly, for the second quarter of 2025, we concluded that this asset group is impaired.
For asset groups where impairment is triggered, we use discounted cash flow models (an income approach) with Level 3 inputs to estimate the fair values of the asset groups.
The significant assumptions used in the discounted cash flow models include projected sublease income over the remaining lease term, expected downtime prior to the commencement of executed or future subleases, and discount rates that reflect a market participant's assumptions in valuing the asset groups.
−Removed: As a result, we recognized impairment charges totaling $ 10.0 million for each of the three- and six-month periods ended June 30, 2025, of which $ 7.4 million and $ 2.6 million, respectively, were related to the tenant improvements and right of use asset associated with the underlying leased property.
+Added: As a result, we recognized impairment charges totaling $ 10.0 million for the second quarter of 2025, of which $ 7.4 million and $ 2.6 million, respectively, were related to the tenant improvements and right of use asset associated with the underlying leased property.
We also identified certain laboratory equipment that we no longer plan to use.
This asset group, consisting of laboratory equipment that would no longer be used going forward, was also determined to not be recoverable.
−Removed: As a result, this asset group was deemed impaired, resulting in a $ 2.2 million impairment charge for each of the three- and six-month periods ended June 30, 2025.
+Added: As a result, this asset group was deemed impaired, resulting in a $ 2.2 million impairment charge for the second quarter of 2025.
The fair value of the lab equipment is classified as Level 3 in the fair value hierarchy due to the use of unobservable inputs utilized, such as estimates provided by third-party vendors.
−Removed: The following table summarizes the restructuring and impairment costs recognized in our unaudited condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2025:
