Changes in liability for pre-existing warranties result from changes in estimates for warranties issued in prior periods.

The Company provides indemnification agreements to certain direct or indirect customers. The Company agrees to reimburse these parties for any damages, costs and expenses incurred by them as a result of legal actions taken against them by third parties for infringing upon their intellectual property rights as a result of using the Company’s products and technologies. These indemnification provisions are varied in scope and are subject to certain terms, conditions, limitations and exclusions. In addition, the Company has entered into indemnification agreements with its directors and officers.

It is not possible to predict the maximum potential amount of future payments under these agreements due to the limited history of indemnification claims and the unique facts and circumstances involved in each particular agreement. There were no indemnification liabilities incurred for the periods presented. However, there can be no assurances that the Company will not incur any financial liabilities in the future as a result of these obligations.

Purchase Commitments

The Company has outstanding purchase obligations with its suppliers and other parties that require the purchases of goods or services. The purchase obligations primarily consist of wafer and other inventory purchases, assembly and other manufacturing services, construction of manufacturing and R&D facilities, purchases of production and other equipment, and license arrangements.

In May 2022, the Company entered into a long-term supply agreement in order to secure manufacturing production capacity for silicon wafers over a four-year period. As of December 31, 2024, the Company had remaining prepayments under this agreement of $60.0 million reported in other long-term assets on the Consolidated Balance Sheets.

Total estimated future unconditional purchase commitments to all suppliers and other parties, net of the $60.0 million prepayment, as of December 31, 2024 were as follows (in thousands):

2025	$	569,637
2026		17,897
2027		29,252
Total	$	616,786

Litigation

The Company is a party to actions and proceedings in the ordinary course of business, including challenges to the enforceability or validity of its intellectual property, claims that the Company’s products infringe on the intellectual property rights of others, and employment matters. The Company has also been subject to litigation initiated by its stockholders. These proceedings often involve complex questions of fact and law and may require the expenditure of significant funds and the diversion of other resources to prosecute and defend. The Company defends itself vigorously against any such claims. As of December 31, 2024, there were no material pending legal proceedings to which the Company was a party.
