We will continue to evaluate our facility needs.
Interest Expense Interest expense consists primarily of interest expense associated with our convertible debt and amortization of debt issuance costs. Interest expense for the year ended December 31, 2024 decreased, compared to the comparable prior year period, in line with our outstanding debt obligations.
Interest expense for the year ended December 31, 2025 increased, compared to the comparable prior year period, due to the amortization of new debt issuance costs from the issuance of the 2030 Notes, partially offset by a reduction in the amortization of debt issuance costs, driven by the repurchase of a portion of the 2026 Notes.
Cost of revenue for the year ended December 31, 2024 decreased, compared to the comparable prior year period, primarily due to a decrease in amortization expenses related to intangible assets acquired through our business combinations, which includes $105 million of incremental expenses in the fourth quarter of 2023 from fully amortizing intangible assets related to the Wētā FX Limited contract that was terminated, a decrease in personnel costs, driven by our reductions in headcount, and a decrease in our hosting expenses in line with decreases in related revenue.
Cost of revenue for the year ended December 31, 2025 was roughly flat, compared to the comparable prior year period, due to a decrease in personnel costs, driven by our reductions in headcount, offset by an increase in hosting and other direct costs to support the revenue growth in our advertising networks.
This resulted in approximately $214 million in employee separation costs, primarily related to the acceleration and modifications of equity awards, and $53 million of non-employee charges associated with these reductions. We are continuing to evaluate our facility needs, and expect more changes in 2025.
In the year ended December 31, 2025, we incurred incremental employee separation costs related to these actions of approximately $33 million, primarily within research and development, and sales and marketing. In addition, we incurred approximately $14 million of non-employee charges associated with this restructuring in 2025.
