Fourth Quarter and Full Year 2024 Financial Results

As of December 31, 2024, Aclaris had aggregate cash, cash equivalents and marketable securities of $203.9 million compared to $181.9 million as of December 31, 2023. The Company believes that its cash, cash equivalents and marketable securities as of December 31, 2024 will be sufficient to fund its operations into 2028, without giving effect to any potential business development transactions or financing activities.

Net loss was $96.6 million for the fourth quarter of 2024 compared to $1.5 million for the fourth quarter of 2023. Net loss was $132.1 million for the year ended December 31, 2024 compared to $88.5 million for the year ended December 31, 2023.

Total revenue was $9.2 million for the fourth quarter of 2024 compared to $17.6 million for the fourth quarter of 2023. The decrease was primarily driven by a one-time upfront payment under the license agreement with Sun Pharmaceutical Industries, Inc. received in the fourth quarter of 2023, offset by the achievement of a commercial milestone under the license agreement with Eli Lilly and Company in the fourth quarter of 2024. Total revenue was $18.7 million for the year ended December 31, 2024 compared to $31.2 million for the year ended December 31, 2023.

Research and development (R&D) expenses were $9.0 million for the quarter ended December 31, 2024 compared to $26.6 million for the prior year period. The $17.6 million decrease was primarily the result of lower zunsemetinib development expenses, lepzacitinib preclinical and clinical development activities, and compensation-related expenses. For the year ended December 31, 2024, R&D expenses were $33.6 million compared to $98.4 million for the year ended December 31, 2023.

General and administrative (G&A) expenses were $5.0 million for the quarter ended December 31, 2024 compared to $8.2 million for the corresponding prior year period. The decrease was primarily due to a reduction in personnel and stock-based compensation expenses. For the year ended December 31, 2024, G&A expenses were $22.2 compared to $32.4 million for the year ended December 31, 2023, primarily due to lower compensation-related costs.

Licensing expenses were $8.6 million for the quarter ended December 31, 2024 compared to $5.7 million for the prior year period. The increase was primarily attributable to a milestone achieved during the fourth quarter of 2024, the entirety of which was payable to a third party. For the year ended December 31, 2024, licensing expenses were $12.7 million compared to $14.7 million for the year ended December 31, 2023.

Revaluation of contingent consideration resulted in a $1.3 million gain for the quarter ended December 31, 2024 compared to a $26.3 million gain for the prior year period. For the year ended December 31, 2024, revaluation of contingent consideration resulted in a charge of $2.5 million compared to a $26.9 million gain for the year ended December 31, 2023.

During the quarter and year ended December 31, 2024, the Company recorded $86.9 million of in-process research and development expenses, representing the fair value of consideration expensed in connection with the in-license of bosakitug (ATI-045) and ATI-052, as well as transaction costs incurred. During the quarter ended December 31, 2023, the Company recorded an intangible asset impairment charge of $6.6 million representing the full balance of its in-process research and development intangible asset.
