8 Plaintiff, ORDER RE MOTION TO DISMISS v. 9 Re: Dkt. No. 127 10 SOLARIA CORPORATION, et al., Defendants. 11

12 13 The partial motion to dismiss of Defendants The Solaria Corporation and Complete 14 Solaria, Inc. (referred to collectively as “Solaria”) was heard before this Court on February 12, 15 2026. Having read the papers filed by the parties and carefully considered their arguments therein 16 and those made at the hearing, as well as the relevant legal authority, the Court GRANTS the 17 motion in part and DENIES it in part for the following reasons. 18 I. BACKGROUND 19 A. Factual Background1 20 1. The Parties’ Relationship 21 In 2015, Plaintiff SolarPark Korea Co. (“SolarPark”) and Solaria began exploring a 22 business partnership under which SolarPark would mass produce shingled solar modules designed 23 by Solaria. First Amended Compl. (Dkt. No. 120, “FAC”) ¶ 10. SolarPark and Solaria executed 24 an Agreement to Manufacture on April 8, 2016 (the “2016 Agreement”). FAC ¶ 11. The 2016 25 Agreement contained a minimum purchase clause which required Solaria to purchase (i) “a total of 26

27 1 “On a motion to dismiss, a court accepts as true a plaintiff’s well-pleaded factual allegations and 1 25 MWp for the first six (6) months of production” and (ii) “a minimum of 10 MWp per quarter 2 for the remaining six (6) quarters.” FAC ¶ 12. 3 On October 6, 2018, SolarPark and Solaria entered into a Technology License Agreement 4 (the “TLA”) setting forth detailed licensing terms and conditions of their respective intellectual 5 property (“IP”). FAC, Ex. B (Dkt. No. 120-2). 6 In April 2019, Solaria proposed expanding the partnership and ramping up production by 7 adding three new production lines at SolarPark’s factory dedicated to Solaria’s products. This 8 expansion required SolarPark to invest approximately $60 million to install new production lines 9 and also double its workforce. FAC ¶ 15. Solaria’s proposal meant increasing production by 10 approximately five times the minimum purchase requirement under the 2016 Agreement (i.e., over 11 200 MW per year). FAC ¶ 16. The expansion also meant that SolarPark would devote nearly its 12 entire manufacturing capacity to Solaria’s orders. FAC ¶ 17. On June 19, 2019, Solaria and 13 SolarPark entered into an Agreement for Supply (the “2019 Agreement”). FAC ¶ 18. Under 14 Sections 2.2 and 3.4 of the 2019 Agreement, Solaria agreed to purchase a minimum volume of 224 15 MW per year (i.e., 164,656 modules per quarter) for five years through June 2024. FAC ¶ 19. 16 To ramp up production as requested by Solaria, SolarPark had to (i) remove the existing 17 equipment for standard modules, (ii) purchase and install new equipment for shingled modules, 18 (iii) hire about 200 additional employees, and (iv) refurbish the production facilities to 19 accommodate the new equipment and personnel. FAC ¶ 20. SolarPark anticipated that such an 20 undertaking would require a capital investment of tens of millions of dollars. Id. As SolarPark 21 could not afford such significant investment, the parties agreed to explore an alternative pricing 22 scheme to account for the upfront costs. Id. To that end, Solaria and SolarPark executed the Solar 23 Module Sales Agreement (the “MSA”) on August 4, 2019. FAC ¶ 21; FAC, Ex. A (Dkt. No. 120- 24 1). The MSA expressly superseded the 2016 Agreement, but not the TLA nor the 2019 25 Agreement. FAC, Ex. A § 1. The MSA provided that “[a]bsolute quantity conditions applied for 26 each quarter” and that SolarPark would provide a volume discount if more than 164,656 modules 27 were purchased each quarter (the “Absolute Quantity Conditions”). FAC, Ex. A § 5.2(c). 1 For three years following execution of the MSA, SolarPark filled all of Solaria’s orders. 2 FAC ¶ 26. Solaria, however, failed to meet the Absolute Quantity Conditions of 164,656 module 3 orders per quarter throughout the period from 3Q 2019 to 1Q 2022. Id. As a result, SolarPark 4 continued to suffer significant financial difficulties and was forced to shut down one of the two 5 factories dedicated to producing Solaria’s shingled modules temporarily on December 31, 2021. 6 FAC ¶ 27. 7 On January 19, 2022, Solaria sent a letter to SolarPark purporting to terminate the MSA as 8 of February 18, 2022. FAC ¶ 28. Although the parties thereafter negotiated a deal to resume 9 production and compensate SolarPark for the losses caused by Solaria’s failure to order minimum 10 volumes, Solaria did not follow through. FAC ¶ 29. 11 On June 28, 2022, Solaria sent a letter to SolarPark purporting to terminate the TLA as of 12 August 31, 2022. FAC ¶ 31. 13 On November 7, 2022, Solaria merged with Complete Solar to form Defendant Complete 14 Solaria, of which Solaria became a wholly owned subsidiary. FAC ¶ 33. Complete Solaria began 15 trading on Nasdaq on July 17, 2023. FAC ¶ 43. On September 20, 2023, Complete Solaria 16 announced that it entered into an Asset Purchase Agreement with Maxeon Solar Technologies, 17 Ltd., and sold off its shingled cell solar panel technology and dealer operations. Id. On 18 September 24, 2024, Complete Solaria purchased certain assets from SunPower Corporation. 19 FAC ¶ 44. On April 21, 2025, Complete Solaria announced its rebrand to SunPower and that its 20 Nasdaq ticker would change to “SPWR.” Id. 21 2. The SIAC Arbitration 22 Solaria commenced an arbitration against SolarPark before the Singapore International 23 Arbitration Centre (“SIAC”) in June 2022 (Case No. ARB160/22/WXZ; the “Arbitration”). FAC 24 ¶ 40; Dkt. No. 127 at 9; Dkt. No. 32-2 ¶ 51. On July 30, 2022, SolarPark counterclaimed against 25 Solaria for breach of the MSA and fraudulent inducement to enter into the MSA (collectively, the 26 “Arbitration Claims”). FAC ¶ 40; Dkt. No. 127 at 9-10; Dkt. No. 115-5. 27 Solaria submitted its Statement of Claim in the Arbitration on February 10, 2023. Dkt. No. 1 May 12, 2023. Dkt. No. 32-3. On November 15, 2023, after being compelled to arbitrate in this 2 action, SolarPark, Solaria, and Complete Solaria reached an agreement to (i) arbitrate Counts III 3 through VI in Plaintiff’s original complaint (Tortious Interference with Contractual Relations 4 against Complete Solaria, Inducement to Breach Contract against Complete solaria, Violation of 5 California’s Unfair Competition Law against all Defendants, and Civil Conspiracy against all 6 Defendants), and (ii) join Complete Solaria as a party to the Arbitration. Dkt. No. 127 at 10; Dkt. 7 No. 103-6. On December 15, 2023, SolarPark submitted in the Arbitration its Statement of 8 Rejoinder and Reply to Counterclaims, in which SolarPark added Counts III through VI of the 9 original complaint to its counterclaims pursuant to the Parties’ agreement. Dkt. No. 127 at 10; 10 Dkt. No. 103-7. On February 16, 2024, Solaria submitted in the Arbitration their Rejoinder to 11 Counterclaims and Response to Additional Claims, in which Solaria pleaded their defenses to both 12 the Arbitration Claims and Counts III through VI. Dkt. No. 103-9. 13 Both SolarPark and Solaria failed to pay their respective portions of the SIAC fees. Dkt. 14 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 15 nonpayment, on June 26, 2024, the SIAC Registrar notified the parties that their claims and 16 counterclaims were considered withdrawn without prejudice to the Parties reintroducing them in 17 another proceeding. Dkt. No. 127 at 5; Dkt. No. 103-18; see also SIAC Rule 34.6(b) (Dkt. No. 18 48-2 at 37) (permitting registrar to deem claims withdrawn without prejudice due to the litigants’ 19 nonpayment of deposits). On July 1, 2024, the SIAC Tribunal confirmed the withdrawal of claims 20 and counterclaims. Dkt. No. 127 at 5; Dkt. No. 103-13.
