When we recognize revenue for sales of modules, we accrue liabilities for the estimated future costs of meeting our limited warranty obligations. We estimate our limited product warranty liability for power output and defects in materials and workmanship under normal use and service conditions based on return rates for each series of module technology and other factors. We make and revise these estimates based primarily on the number of solar modules under warranty installed at customer locations, our historical experience with and projections of warranty claims, and our estimated per-module replacement costs. We also monitor our expected future module performance through certain quality and reliability testing and actual performance in certain field installation sites. From time to time, we have taken remediation actions with respect to affected modules beyond our limited warranties and may elect to do so in the future, in which case we would incur additional expenses. Such potential voluntary future remediation actions beyond our limited warranty obligations may be material to our condensed consolidated statements of operations if we commit to any such remediation actions.

During the year ended December 31, 2024, we identified manufacturing issues affecting certain Series 7 modules manufactured in 2023 and 2024 that may cause the modules to experience premature power loss once installed in the field. The ultimate loss we will incur for these manufacturing issues will depend on the extent of the premature power loss that is experienced in relation to the obligations under our limited product warranties, as well as any potential additional commitments we may make to remediate the affected modules. Based on currently available information and certain assumptions and estimates, we believe a reasonable estimate of the aggregate losses related to these manufacturing issues will range from approximately $56 million to $100 million. At this time, no individual amount within that range is a better estimate than any other amount. Accordingly, as of December 31, 2024, we increased our product warranty liability by the low end of the range, which we recorded as a reduction to revenue. The estimated range set forth above was based on our evaluation of the currently available information, including select samples of module performance data from several locations, the estimated number of affected modules, and projections of probable costs to remediate the issues. As additional information becomes available to us, our estimate of the aggregate losses related to these manufacturing issues may change, and any change in estimate may also result in a change to our product warranty liability.

In certain limited circumstances, we have provided indemnifications to customers or other parties under which we are contractually obligated to compensate such parties for losses they suffer resulting from a breach of a representation, warranty, or covenant; the resolution of specific matters associated with a solar project’s development or construction; guarantees of a third party’s payment or performance obligations; or any disallowance or lack of the right to claim all or any portion of certain tax credits. For contracts that have such indemnification provisions, we initially recognize a liability under ASC 460 for the estimated premium that would be required by a guarantor to issue the same indemnity in a standalone arm’s-length transaction with an unrelated party. We may base these estimates on the cost of insurance or other instruments that cover the underlying risks being indemnified and may purchase such instruments to mitigate our exposure to potential indemnification payments. We subsequently measure such liabilities at the greater of the initially estimated premium or the contingent liability required to be recognized under ASC 450. We recognize any indemnification liabilities as a reduction of earnings associated with the related transaction.

After an indemnification liability is recorded, we derecognize such amount pursuant to ASC 460 depending on the nature of the indemnity, which derecognition typically occurs upon expiration or settlement of the arrangement, and any contingent aspects of the indemnity are accounted for in accordance with ASC 450. As of March 31, 2025 and December 31, 2024, we accrued $0.3 million and $2.5 million of current indemnification liabilities, respectively. As of March 31, 2025, the maximum potential amount of future payments under our indemnifications was $1.5 billion.

As part of a business acquisition in May 2023, we agreed to pay additional consideration of up to $42.5 million to the selling shareholders contingent upon the successful achievement of certain technical milestones. As of March 31, 2025 and December 31, 2024, we recorded $6.5 million of long-term liabilities for such contingent obligation based on its estimated fair value.

We previously established a module collection and recycling program, which has since been discontinued, to collect and recycle modules sold and covered under such program once the modules reach the end of their service lives. For legacy customer sales contracts that are covered under this program, we agreed to pay the costs for the collection and recycling of qualifying solar modules, and the end-users agreed to notify us, disassemble their solar power systems, package the solar modules for shipment, and revert ownership rights over the modules back to us at the end of the modules’ service lives. Accordingly, we recorded any collection and recycling obligations within “Cost of sales” at the time of sale based on the estimated cost to collect and recycle the covered solar modules.

We estimate the cost of our collection and recycling obligations based on the present value of the expected future cost of collecting and recycling the solar modules, which includes estimates for the cost of packaging materials; the cost of freight from the solar module installation sites to a recycling center; material, labor, and capital costs; and by-product credits for certain materials recovered during the recycling process. We base these estimates on our experience collecting and recycling solar modules and certain assumptions regarding costs at the time the solar modules will be collected and recycled. In the periods between the time of sale and the related settlement of the collection and recycling obligation, we accrete the carrying amount of the associated liability and classify the corresponding expense within “Selling, general and administrative” expense on our condensed consolidated statements of operations.

During the year ended December 31, 2022, we received several indemnification demands from certain customers, for whom we provided EPC services, regarding claims that such customers’ PV tracker systems infringe, in part, on patents owned by Rovshan Sade (“Plaintiff”), the owner of a company called Trabant Solar, Inc. In January 2023, we were notified by two of our customers that Plaintiff served them with patent infringement complaints, and we have assumed the defense of these claims. We have conducted due diligence on the patents and claims and believe that we will prevail in the actions. In April 2023, we commenced an Inter Partes Review (“IPR”) before the United States Patent and Trademark Office seeking to invalidate such claims. In November 2023, the United States Patent Trial and Appeal Board declined to hear the First Solar IPR. In July 2024, Plaintiff’s counsel filed a motion seeking to withdraw as counsel. The court granted the motion and issued a 45-day stay of all proceedings while Plaintiff seeks new representation. In September and December 2024, Plaintiff filed motions seeking a stay of all proceedings, claiming health issues. The court issued additional stays of all proceedings until March 2025. On March 20, 2025, the parties met to mediate the case but were unable to agree on a settlement. The court subsequently denied Plaintiff’s motion seeking a stay of all proceedings. At this time, we are not in a position to assess the likelihood of any potential loss or adverse effect on our financial condition or to estimate the amount or range of possible loss, if any, from these actions.

In April 2019, a subcontractor of First Solar sustained certain injuries while performing work at a former project site and, in May 2019, commenced legal action against a subsidiary of the Company. In June 2023, a jury awarded damages of approximately $51.3 million to the plaintiff. On September 21, 2023, the Superior Court of California for Monterey County ruled, in response to a motion for remittitur filed by the Company, that the damages awarded to the plaintiff were excessive and reduced the award from $51.3 million to $21.8 million. The plaintiff and defendant have appealed and cross appealed varying aspects of the verdict and the remittitur. Accordingly, due to the uncertainty surrounding the multiple decisions and appeals, as of March 31, 2025, we recorded a $21.8 million accrued litigation payable included in “Other current liabilities” in our condensed consolidated balance sheet. We believe the full amount of awarded damages will be covered by our various insurance policies. Accordingly, we also recorded a $21.8 million receivable included in “Other current assets” in our condensed consolidated balance sheet as of March 31, 2025. The plaintiff did not accept the reduced award by the court ordered deadline of October 10, 2023, and, as a result, the $21.8 million award has been vacated, and a new trial will be scheduled. We, in conjunction with our insurance carriers, are challenging the initial verdict in an appellate court, and the plaintiff is cross appealing from the decision to reduce the award, among other issues, stemming from the trial. We filed our initial briefs with the court on December 20, 2024.

On September 29, 2023 and June 5, 2024, the Company received subpoenas from the Division of Enforcement of the SEC seeking documents and information relating to the Company’s operations in India, the Company's entry into a PV module supply agreement with an India-based customer, and certain aspects of the Company's technology roadmap, among other things. The Company is cooperating with the SEC and cannot predict the ultimate timing, scope, or outcome of this matter.

We are party to other legal matters and claims in the normal course of our operations. While we believe the ultimate outcome of these matters and claims will not have a material adverse effect on our financial position, results of operations, or cash flows, the outcome of such matters and claims is not determinable with certainty, and negative outcomes may adversely affect us.
