Our long-term inventory, which is fully reserved as of December 31, 2024, consists of excess raw materials that remain viable but with limited market opportunities. The following table summarizes the changes in our allowance for obsolescence for the periods presented:
| Year Ended December 31,
| 2024 |  | 2023 |  | 2022
Beginning balance | $ | 4,004 |  |  | $ | 120 |  |  | $ | 64 |
Allowance for obsolescence | 1,863 |  |  | 3,965 |  |  | 83 |
Write-offs | — |  |  | (81) |  |  | (27) |
Ending balance | $ | 5,867 |  |  | $ | 4,004 |  |  | $ | 120 |
The allowance for 2023 was primarily related to our decision to cease future compressor assembly at our Midland, Texas facility, which reduced the expected future demand of certain inventory items held at this facility. In 2024, we continued actions in support of our strategy to further outsource assembly activities to third parties resulting in an additional allowance charge.
