13 I. INTRODUCTION 14 Plaintiffs, Albireo Energy LLC and Albireo Holdings Inc. (collectively, “Albireo”) brought 15 this action against three former employees—Ivan Aron, Ryan Cowper, and Gregory Siefferman— 16 and a competitor, ATS Automation Inc., alleging breach of contractual obligations and fiduciary 17 duties, misappropriation of trade secrets, unfair competition, tortious interference with business 18 expectancy and with contract, and civil conspiracy. Am. Compl., ECF No. 3. Currently pending 19 before the Court is Plaintiffs’ Motion for a Preliminary Injunction, ECF No. 13, against Ivan Aron. 20 21 22 23

24 ORDER DENYING PRELIMINARY INJUNCTION 1 Having reviewed the materials1 and the relevant legal authorities, the Court will deny the motion. 2 The reasoning for the Court’s decision follows. 3 II. BACKGROUND 4 Plaintiff Albireo Energy, a wholly owned subsidiary of Albireo Holdings, provides building 5 controls and energy services to commercial and institutional facilities across the United States and 6 abroad. Am. Compl. ¶¶ 11-12, 14. Ivan Aron was employed by Albireo Energy as the General 7 Manager/Vice President from August 2021 to September 2025. Id. ¶ 37. He is also a shareholder 8 of Albireo Holdings. Id. ¶¶ 40-41, 51. Defendants Siefferman and Cowper were also employed by 9 Albireo Energy until July and September 2025 respectively. Id. ¶¶ 21, 25. Defendants Aron, 10 Siefferman, and Cowper (the “Individual Defendants”) are all current employees of Defendant 11 ATS, a direct competitor of Albireo Energy. Id. ¶¶ 3, 4, 6, 69. Plaintiffs allege that the Individual 12 Defendants use confidential knowledge they learned while employed with Albireo Energy to divert 13 Albireo Energy’s business opportunities to ATS. Id. ¶¶ 60-63, 70, 76, 80. 14 Relevant to this motion, Plaintiffs allege that Defendant Aron breached multiple restrictive 15 covenants, contained in his Non-Solicitation Agreement, Stockholders Agreement, and Separation 16 Agreement, when he joined ATS and diverted Washington customers to ATS, specifically key 17 accounts with Sound Transit and McKinstry Co., LLC. Am. Compl. ¶¶ 42-50, 53-58, 85-87, 107- 18 114; Mot. 1, 3-4. Plaintiffs seek to enjoin Defendant Aron from taking further acts that “imperil 19 Albireo Energy’s trade secrets, including competing against them at ATS in the same market and 20 soliciting Albireo Energy’s employees, clients, or vendors.” Mot. 13. 21

22 1 Including the motion, ECF No.13; modified response in opposition, ECF No. 28-1; and Plaintiffs’ reply, ECF No. 23 24; together with attached exhibits and declarations.

24 ORDER DENYING PRELIMINARY INJUNCTION 1 III. LEGAL STANDARD 2 “A preliminary injunction is an extraordinary and drastic remedy; it is never awarded as of 3 right.” Munaf v. Geren, 553 U.S. 674, 689-90 (2008) (internal citations omitted). For a preliminary 4 injunction to issue, the moving party has the burden of demonstrating all four of the following 5 elements: (1) that it is likely to succeed on the merits; (2) that it is likely to suffer irreparable harm 6 in the absence of preliminary relief; (3) that the balance of equities tips in its favor; and (4) that an 7 injunction serves the public interest. Winter v. Nat. Res. Def. Council, Inc., 555 U.S. 7, 20 (2008).2 8 The Ninth Circuit follows a “‘sliding scale’ approach to evaluating the first and third Winter 9 elements, [where] a preliminary injunction may be granted when there are ‘serious questions going 10 to the merits and a hardship balance that tips sharply toward the plaintiff,’ so long as ‘the other two 11 elements of the Winter test are also met.’” Ass’n des Eleveurs de Canards et d’Oies du Quebec v.

12 Harris, 729 F.3d 937, 944 (9th Cir. 2013) (quoting Alliance for the Wild Rockies v. Cottrell, 632 13 F.3d 1127, 1131–32 (9th Cir. 2011)); see also All. for the Wild Rockies v. Pena, 865 F.3d 1211, 14 1217 (9th Cir. 2017) (referring to the original Winter standard and the “sliding scale” variant, the 15 Court stated: “A party seeking a preliminary injunction must meet one of two variants of the same 16 standard.”). Further, to obtain injunctive relief, “plaintiffs must establish that irreparable harm is 17 likely, not just possible, in order to obtain a preliminary injunction.” Alliance for the Wild Rockies, 18 632 F.3d at 1131. 19 20

21 2 “Due to the urgency of obtaining a preliminary injunction at a point when there has been limited factual development, the rules of evidence do not apply strictly to preliminary injunction proceedings.” Herb Reed Enters., LLC v. Florida 22 Ent. Mgmt., Inc., 736 F.3d 1239, 1250 n. 5 (9th Cir. 2013). “In deciding a motion for a preliminary injunction, the district court ‘is not bound to decide doubtful and difficult questions of law or disputed questions of fact.’” Int'l Molders’ & Allied Workers' Local Union No. 164 v. Nelson, 799 F.2d 547, 551 (9th Cir. 1986) (quoting Dymo Indus., 23 Inc. v. Tapeprinter, Inc., 326 F.2d 141, 143 (9th Cir.1964)).

24 ORDER DENYING PRELIMINARY INJUNCTION 1 IV. DISCUSSION 2 A. Likelihood of success on the merits 3 Plaintiffs must make a clear showing that they are likely to succeed on the merits. Defendant 4 Aron argues that the agreements being asserted by Plaintiffs against him are illegal and 5 unenforceable under Washington law. Opp’n 2, 5-11. Aron contends that the restrictive covenants 6 are noncompetition covenants prohibited under Washington law. Opp’n 5-6 (citing RCW 7 49.62.010). Therefore, the Court will begin by resolving whether the restrictive covenants at issue 8 are enforceable. 9 1. Enforceability of restrictive covenants 10 Plaintiffs attached the following agreements with Aron to the Amended Complaint: (1) 11 Confidentiality & Non-Solicitation Agreement, Ex. B; (2) Non Disclosure Agreement, Ex. C; (3)

12 Joinder, Ex. D; (4) Amended and Restated Stockholders’ Agreement, Ex. E; and (5) Separation 13 Agreement, Ex. F. In their complaint, Plaintiffs allege that under the various agreements’ restrictive 14 covenant provisions, Aron agreed that he would not solicit Plaintiffs’ employees or customers and 15 would maintain confidential and trade secret information. Am. Compl. ¶¶ 43- 51 (citing Exs. B, C, 16 E, F). 17 Under the Confidentiality & Non-Solicitation Agreement, Aron is prohibited from soliciting 18 customers or employees during employment “and for two (2) years thereafter.” Am. Compl. Ex. B. 19 The Non Disclosure Agreement requires Aron to acknowledge that all classified, non-classified, 20 and sensitive information belongs to Albireo Energy, to refrain from divulging such information to 21 anyone outside the Company, and to promptly return all documents and other materials when his

22 employment ends. Id. Ex. C. Under the Stockholders’ Agreement, Aron is prohibited from 23 competing with Plaintiffs and from soliciting any of Plaintiffs’ clients and vendors, while he owns
