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 consolidated statements of operations if we commit to any such remediation actions.

We have 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.

During the year ended December 31, 2023, we revised our warranty estimate based on updated information regarding our warranty claims, which reduced our module warranty liability by $5.4 million. This updated information reflected lower-than-expected warranty claims for our older series of module technology and revisions to projected settlements, resulting in reductions to our projected module return rate. During the year ended December 31, 2022, we revised the warranty estimate based on updated information regarding our warranty claims, which reduced our module warranty liability by $10.2 million. This updated information reflected lower-than-expected warranty claims for our older series of module technology as well as the evolving claims profile of our newest series of module technology, resulting in reductions to our projected module return rates.

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 December 31, 2024 and 2023, we accrued $2.5 million and $3.3 million of current indemnification liabilities, respectively. As of December 31, 2024, the maximum potential amount of future payments under our indemnifications was $1.3 billion.

As part of our acquisition of Evolar 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. See Note 3. “Business Acquisitions” to our consolidated financial statements for further discussion of this acquisition. As of December 31, 2023, we recorded $7.5 million of current liabilities and $11.0 million of long-term liabilities for such contingent obligations based on their estimated fair values.

During the year ended December 31, 2024, we paid $7.5 million of contingent consideration to the selling shareholders based on the achievement of specific milestones. As of December 31, 2024, the remaining long-term contingent consideration liability was remeasured to a fair value of $6.5 million. The remeasurement resulted from adjustments in the probability and timing of achieving the remaining milestones. The changes in the fair value of the contingent consideration arrangement are classified within “Research and development” expense in our consolidated statements of operations.

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 consolidated statements of operations.

We periodically review our estimates of expected future recycling costs and may adjust our liability accordingly. Such adjustments are presented within “Cost of sales” on our consolidated statements of operations. During the years ended December 31, 2024 and 2023, we completed our annual cost study of obligations under our module collection and recycling program and determined that no adjustment to the associated liability was necessary. During the year ended December 31, 2022, we completed our annual cost study of obligations under our module collection and recycling program and reduced the associated liability by $7.5 million primarily due to lower estimated capital and chemical costs resulting from improvements to our module recycling technology.

Our module collection and recycling liability was $134.4 million and $135.1 million as of December 31, 2024 and 2023, respectively. During the years ended December 31, 2024, 2023, and 2022, we recognized accretion expense of $5.8 million, $5.5 million, and $5.5 million, respectively, associated with this liability. See Note 7. “Restricted Marketable Securities” to our consolidated financial statements for more information about our arrangements for funding this liability.

In January 2022, a putative class action lawsuit titled City of Pontiac General Employees’ Retirement System v. First Solar, Inc., et al., Case No. 2:22-cv-00036-MTL, was filed in the United States District Court for the District of Arizona (hereafter “Arizona District Court”) against the Company and certain of our current officers (collectively, “Putative Class Action Defendants”). The complaint was filed on behalf of a purported class consisting of all purchasers of First Solar common stock between February 22, 2019 and February 20, 2020, inclusive. The complaint asserts violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 based on allegedly false and misleading statements related to the Company’s Series 6 solar modules and its project development business. It seeks unspecified damages and an award of costs and expenses. On April 25, 2022, the Arizona District Court issued an order appointing the Palm Harbor Special Fire Control & Rescue District Firefighters’ Pension Plan and the Greater Pennsylvania Carpenters’ Pension Fund as Lead Plaintiffs. On June 23, 2022, Lead Plaintiffs filed an Amended Complaint that brought the same claims and sought the same relief as the original complaint. On January 10, 2023, the Court granted the Putative Class Action Defendants’ motion to dismiss in full, with leave to amend by February 10, 2023. On February 10, 2023, Lead Plaintiffs filed a Second Amended Complaint. Putative Class Action Defendants filed a motion to dismiss the Second Amended Complaint on February 24, 2023. Lead Plaintiffs filed their opposition to the motion to dismiss on March 10, 2023, and Putative Class Action Defendants filed a reply in support of their motion to dismiss on March 17, 2023. On June 23, 2023, the Court granted the Putative Class Action Defendants’ motion to dismiss with prejudice. On July 14, 2023, the Clerk of Court entered judgment in favor of the Putative Class Action Defendants. Lead Plaintiffs did not file an appeal, and the judgment in favor of the Putative Class Action Defendants is now final.

In September 2022, a derivative action titled Federman v. Widmar, et al., Case No. 2:22-cv-01541-JAT, was filed by a putative stockholder purportedly on behalf of the Company in the Arizona District Court against our current directors and certain officers of the Company (collectively, “Derivative Action Defendants”), alleging violations of Section 14(a) of the Securities Exchange Act of 1934, breach of fiduciary duties, contribution and indemnification, aiding and abetting, and gross mismanagement. The complaint generally alleges that the Derivative Action Defendants caused or allowed false and misleading statements to be made concerning the Company’s Series 6 modules and project development business. The action includes claims for, among other things, damages in favor of the Company and an award of costs and expenses to the putative plaintiff stockholder, including attorneys’ fees. The Company believes that the plaintiff in the derivative action lacks standing to pursue litigation on behalf of First Solar. On February 17, 2023, the case was transferred to Judge Liburdi, who is also presiding over the related putative class action. On March 10, 2023, the plaintiff filed an Amended Complaint. On April 10, 2023, the Derivative Action Defendants filed a motion to dismiss the Amended Complaint. The plaintiff filed its opposition to the motion to dismiss on May 17, 2023, and the Derivative Action Defendants filed a reply in support of their motion to dismiss on June 17, 2023. Given the Court’s dismissal of the putative class action, the parties agreed that the claims in the Derivative Action should be dismissed with prejudice and filed a joint stipulation to that effect on September 7, 2023. On September 8, 2023, the Court ordered the Clerk of Court to dismiss the action with prejudice.

In July 2021, Southern Power Company and certain of its affiliates (“Southern”) filed an arbitration demand with the American Arbitration Association against two subsidiaries of the Company, alleging breach of the EPC agreements for five projects in the United States, for which the Company’s subsidiaries served as the EPC contractor. The arbitration demand asserts breach of obligations to design and engineer the projects in accordance with the EPC agreements, particularly as such obligations relate to the procurement of tracker systems and inverters. The Company and its subsidiaries denied the claims, and defended the claims in arbitration hearings, which concluded in February 2023. In May 2023, the parties submitted their final proposals of individual award claims to the arbitration panel. In July 2023, the arbitration panel entered an interim award to Southern for $35.6 million, which was paid during the year ended December 31, 2023. As a result, we recognized a loss for such interim award in our results of operations for the year ended December 31, 2023. The final arbitration award, which did not change the results of the interim award, was signed on November 6, 2023. On February 2, 2024, First Solar commenced an action in the New York County Supreme Court seeking to vacate certain aspects of the final award. On May 6, 2024, such action was denied. First Solar has elected not to appeal, and considers this matter closed.

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 initially granted the motions and issued additional stays of all proceedings until March 2025 and subsequently ordered both parties to mediate the case, which is expected to take place during the week of March 17, 2025. 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 December 31, 2024, we recorded a $21.8 million accrued litigation payable included in “Other current liabilities” in our 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 consolidated balance sheet as of December 31, 2024. 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. The plaintiff’s briefs are due by March 24, 2025.

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.
