OPINION _________________

KAREN NELSON MOORE, Circuit Judge. Robert Boyd wanted to exit from his company. In 2019, he had sold a majority stake in Northern Biomedical Research, Inc. (“NBR”) to the individual defendants in this case: Shane Woods, Dean Haan, Joshua Bartoe, and Mark Johnson. He retained a 16% stake in the business but had moved from its headquarters in Michigan to a ranch in Idaho and had grown increasingly frustrated with the management of the company that he started several decades earlier. At the same time, the individual defendants were seeking to expand. NBR lacked the cash or revenue to fund that expansion, so the defendants began exploring a potential loan, and they also considered equity financing options. But they told Boyd little or nothing about these efforts, particularly with respect to the company’s interest in equity financing and early overtures from Avista Capital Partners, LLP (“Avista”), the venture capital firm that would wind up taking a 50% stake in NBR.

Boyd sold his shares in December 2020 for about $3.4 million, an amount based on an agreed-upon accounting firm’s annual valuation of NBR at roughly $21 million. The next spring, Avista and NBR entered an agreement for a capital infusion of $40 million, thus valuing the company at $80 million. Unhappy that he sold his stake in NBR for less than he might have later received, Boyd sued the company and the individual defendants, alleging that their failure to inform him about their discussions with Avista or the fact that NBR was considering private- equity financing violated securities law and breached the defendants’ fiduciary duties under Michigan common law. After discovery, the district court granted summary judgment to the defendants on all counts. This appeal followed.

We hold that the district court did not err when it granted summary judgment on Boyd’s securities-law claims. But because it applied an incorrect legal standard under Michigan common law, a genuine dispute of material fact remains as to whether Boyd is entitled to relief on Counts III, IV, and V of his second amended complaint. We therefore affirm in part and reverse in part. No. 25-1001 Boyd v. N. Biomedical Research et al. Page 3

I. BACKGROUND

A. Factual Background

In 2019, the individual defendants began talks with Boyd, who they learned was interested in selling his company, NBR. R. 168-3 (Bartoe Dep. at 21) (Page ID #3717). On September 1, 2019, their company, BHJW, acquired NBR. Id. at 21–23 (Page ID #3717). The post-acquisition shareholders of BHJW—the individual defendants along with Boyd and two other NBR employees—entered into a shareholder agreement. R. 168-45 (Shareholder Agreement at 1) (Page ID #3911). BHJW, which soon changed its name to Northern Biomedical Research to reflect continuity, had 10,000 outstanding shares, of which Boyd held 1,600. Id.; R. 168-52 (Redemption Docs. at 1) (Page ID #4013); D. 26 (Appellant Br. at 23).1 The new NBR owned the company’s operations and physical assets, but Boyd himself retained the company’s real estate, which NBR leased back from him. R. 168-46 (Lease at 1–12) (Page ID #3935–47). Boyd also agreed to extend a $400,000 line of credit to the new company. R. 168-45 (Shareholder Agreement at 10–11) (Page ID #3920–21).

Boyd’s role in the company after the 2019 sale is not entirely clear. After the acquisition, Haan sent emails to customers stating that Boyd “will continue on as a senior scientific advisor and Chairman of the Board of the new company.” R. 168-11 (Haan Customer Email) (Page ID #3795). Boyd asserts that he remained as an employee from September 2019 to January 2020. R. 168-4 (Boyd Dep. at 90–91) (Page ID #3739). But there “wasn’t a great relationship” between Boyd and new management, so in January 2020 Boyd left day-to-day employment at NBR and moved to Idaho. Id. at 91–93 (Page ID #3739); R. 48-1 (Residency Documents) (Page ID #890–94). Boyd believed, however, that he “more or less” remained chairman of the board of directors. R. 168-4 (Boyd Dep. at 52–53) (Page ID #3732). He formally resigned as “an officer, director and employee” of NBR on December 17, 2020, when he sold his stock in the company. R. 168-13 (Resignation) (Page ID #3800–02); R. 168-52 (Redemption Docs. at 25) (Page ID #4013).

1 To avoid confusion, we refer to both the pre- and post-acquisition companies as NBR throughout. No. 25-1001 Boyd v. N. Biomedical Research et al. Page 4

In the meantime, the individual defendants began to focus on expanding NBR’s facilities and operations to allow it to take on more clients because the company was “routinely turning away about twice as much work” as it could actually undertake. R. 168-48 (Bartoe Dep. at 44) (Page ID #3963). Haan led the initial exploration of financing options for such an expansion. Id. at 43–44 (Page ID #3963). The directors knew that the costs could run on the scale of tens of millions of dollars. R. 168–47 (Boyd Dep. at 99–102) (Page ID #3959–60).

In June 2020, Haan visited Boyd in Idaho, where they discussed purchasing the facility from Boyd, redeeming Boyd’s stock, and financing NBR’s expansion. Haan recounted their discussion of financing options, recalling “going over in generalities the options that [he] had explored,” which included “senior debt, junior debt, mezzanine debt . . . venture capitalism and private equity.” R. 168-2 (Haan Dep. at 76–77) (Page ID #3699–3700). Boyd recalled Haan discussing the possibility of a loan from Mercantile Bank to fund the purchase of his stock, and Boyd then said that he’d told Haan he had “always been . . . against capital venture [sic] investment, that you lose control and you are no longer making the decisions.” R. 168-4 (Boyd Dep. at 42–43 (Page ID #3731). Boyd testified that when they discussed financing the facility expansion, Haan had “talked about acquiring a loan” from Mercantile Bank “for that expansion” too. Id. at 44 (Page ID #3731). In response to a follow-up question as to whether “Haan sa[id] something about private equity investments,” Boyd responded: “I have been consistently against private equity . . . and losing control. And I’m sure that we talked about losing control and control of the company because these people were having managerial conflicts . . . .” Id. at 44– 45 (Page ID #3731).

Shortly thereafter, Haan and NBR began seeking financing for the expansion in earnest. In an October 22, 2020 email to the NBR shareholders (except for Boyd), Haan sketched out the various options for raising capital, which focused on debt but also referenced the possibility of a private-equity investment.
