Opinion

SOLARPARK KOREA CO., LTD., Case No. 23-cv-01181-AMO

Plaintiff, ORDER RE MOTION TO DISMISS v. Re: Dkt. No. 127 SOLARIA CORPORATION, et al., Defendants.

The partial motion to dismiss of Defendants The Solaria Corporation and Complete Solaria, Inc. (referred to collectively as “Solaria”) was heard before this Court on February 12, 2026. Having read the papers filed by the parties and carefully considered their arguments therein and those made at the hearing, as well as the relevant legal authority, the Court GRANTS the motion in part and DENIES it in part for the following reasons. A. Factual Background1 1. The Parties’ Relationship In 2015, Plaintiff SolarPark Korea Co. (“SolarPark”) and Solaria began exploring a business partnership under which SolarPark would mass produce shingled solar modules designed by Solaria. First Amended Compl. (Dkt. No. 120, “FAC”) ¶ 10. SolarPark and Solaria executed an Agreement to Manufacture on April 8, 2016 (the “2016 Agreement”). FAC ¶ 11. The 2016 Agreement contained a minimum purchase clause which required Solaria to purchase (i) “a total of

On October 6, 2018, SolarPark and Solaria entered into a Technology License Agreement (the “TLA”) setting forth detailed licensing terms and conditions of their respective intellectual property (“IP”). FAC, Ex. B (Dkt. No. 120-2). In April 2019, Solaria proposed expanding the partnership and ramping up production by adding three new production lines at SolarPark’s factory dedicated to Solaria’s products. This expansion required SolarPark to invest approximately $60 million to install new production lines and also double its workforce. FAC ¶ 15. Solaria’s proposal meant increasing production by approximately five times the minimum purchase requirement under the 2016 Agreement (i.e., over 200 MW per year). FAC ¶ 16. The expansion also meant that SolarPark would devote nearly its entire manufacturing capacity to Solaria’s orders. FAC ¶ 17. On June 19, 2019, Solaria and SolarPark entered into an Agreement for Supply (the “2019 Agreement”). FAC ¶ 18. Under Sections 2.2 and 3.4 of the 2019 Agreement, Solaria agreed to purchase a minimum volume of 224 MW per year (i.e., 164,656 modules per quarter) for five years through June 2024. FAC ¶ 19. To ramp up production as requested by Solaria, SolarPark had to (i) remove the existing equipment for standard modules, (ii) purchase and install new equipment for shingled modules, (iii) hire about 200 additional employees, and (iv) refurbish the production facilities to accommodate the new equipment and personnel. FAC ¶ 20. SolarPark anticipated that such an undertaking would require a capital investment of tens of millions of dollars. Id. As SolarPark could not afford such significant investment, the parties agreed to explore an alternative pricing scheme to account for the upfront costs. Id. To that end, Solaria and SolarPark executed the Solar Module Sales Agreement (the “MSA”) on August 4, 2019. FAC ¶ 21; FAC, Ex. A (Dkt. No. 120- 1). The MSA expressly superseded the 2016 Agreement, but not the TLA nor the 2019 Agreement. FAC, Ex. A § 1. The MSA provided that “[a]bsolute quantity conditions applied for each quarter” and that SolarPark would provide a volume discount if more than 164,656 modules were purchased each quarter (the “Absolute Quantity Conditions”). FAC, Ex. A § 5.2(c). For three years following execution of the MSA, SolarPark filled all of Solaria’s orders. FAC ¶ 26. Solaria, however, failed to meet the Absolute Quantity Conditions of 164,656 module orders per quarter throughout the period from 3Q 2019 to 1Q 2022. Id. As a result, SolarPark continued to suffer significant financial difficulties and was forced to shut down one of the two factories dedicated to producing Solaria’s shingled modules temporarily on December 31, 2021. FAC ¶ 27. On January 19, 2022, Solaria sent a letter to SolarPark purporting to terminate the MSA as of February 18, 2022. FAC ¶ 28. Although the parties thereafter negotiated a deal to resume production and compensate SolarPark for the losses caused by Solaria’s failure to order minimum volumes, Solaria did not follow through. FAC ¶ 29. On June 28, 2022, Solaria sent a letter to SolarPark purporting to terminate the TLA as of August 31, 2022. FAC ¶ 31. On November 7, 2022, Solaria merged with Complete Solar to form Defendant Complete Solaria, of which Solaria became a wholly owned subsidiary. FAC ¶ 33. Complete Solaria began trading on Nasdaq on July 17, 2023. FAC ¶ 43. On September 20, 2023, Complete Solaria announced that it entered into an Asset Purchase Agreement with Maxeon Solar Technologies, Ltd., and sold off its shingled cell solar panel technology and dealer operations. Id. On September 24, 2024, Complete Solaria purchased certain assets from SunPower Corporation. FAC ¶ 44. On April 21, 2025, Complete Solaria announced its rebrand to SunPower and that its Nasdaq ticker would change to “SPWR.” Id. 2. The SIAC Arbitration Solaria commenced an arbitration against SolarPark before the Singapore International Arbitration Centre (“SIAC”) in June 2022 (Case No. ARB160/22/WXZ; the “Arbitration”). FAC ¶ 40; Dkt. No. 127 at 9; Dkt. No. 32-2 ¶ 51. On July 30, 2022, SolarPark counterclaimed against Solaria for breach of the MSA and fraudulent inducement to enter into the MSA (collectively, the “Arbitration Claims”). FAC ¶ 40; Dkt. No. 127 at 9-10; Dkt. No. 115-5. Solaria submitted its Statement of Claim in the Arbitration on February 10, 2023. Dkt. No. May 12, 2023. Dkt. No. 32-3. On November 15, 2023, after being compelled to arbitrate in this action, SolarPark, Solaria, and Complete Solaria reached an agreement to (i) arbitrate Counts III through VI in Plaintiff’s original complaint (Tortious Interference with Contractual Relations against Complete Solaria, Inducement to Breach Contract against Complete solaria, Violation of California’s Unfair Competition Law against all Defendants, and Civil Conspiracy against all Defendants), and (ii) join Complete Solaria as a party to the Arbitration. Dkt. No. 127 at 10; Dkt. No. 103-6. On December 15, 2023, SolarPark submitted in the Arbitration its Statement of Rejoinder and Reply to Counterclaims, in which SolarPark added Counts III through VI of the original complaint to its counterclaims pursuant to the Parties’ agreement. Dkt. No. 127 at 10; Dkt. No. 103-7. On February 16, 2024, Solaria submitted in the Arbitration their Rejoinder to Counterclaims and Response to Additional Claims, in which Solaria pleaded their defenses to both the Arbitration Claims and Counts III through VI. Dkt. No. 103-9. Both SolarPark and Solaria failed to pay their respective portions of the SIAC fees. Dkt. No. 103-3 at 4; Dkt. No. 113-3 at 2, 6, 10, 17; Dkt. No. 105-11 at 2; Dkt. No. 105-14. Due to the nonpayment, on June 26, 2024, the SIAC Registrar notified the parties that their claims and counterclaims were considered withdrawn without prejudice to the Parties reintroducing them in another proceeding. Dkt. No. 127 at 5; Dkt. No. 103-18; see also SIAC Rule 34.6(b) (Dkt. No. 48-2 at 37) (permitting registrar to deem claims withdrawn without prejudice due to the litigants’ nonpayment of deposits). On July 1, 2024, the SIAC Tribunal confirmed the withdrawal of claims and counterclaims. Dkt. No. 127 at 5; Dkt. No. 103-13. On November 18, 2024, the SIAC Registrar notified the parties regarding the final settlement of their accounts. Dkt. No. 103-20. B. Procedural History SolarPark initiated this lawsuit on March 16, 2023. Dkt. No. 1. In May 2023, SolarPark filed a motion for preliminary injunction, Dkt. No. 28, after which Solaria filed a motion to dismiss, Dkt. No. 32. Both motions were heard and decided together. See Dkt. No
