SEITZ, Chief Justice:

Stillwater Mining Company filed suit against its directors’ and officers’

liability insurers to recover the expenses it incurred defending a Delaware stockholder appraisal action. The Superior Court granted the insurers’ motions to dismiss after it found that Delaware law applied to the dispute and our Court’s decision in In re Solera Ins. Coverage Appeals (“Solera II”) precluded coverage for losses incurred in a stockholder appraisal action under a similar D&O policy.

The main issue on appeal is whether Delaware or Montana law applies to the claims in Stillwater’s amended complaint. Stillwater argues that the Superior Court should have applied Montana law because Montana has the most significant relationship to the dispute and the parties. If Montana law applies, according to Stillwater, it can recover its defense costs – not because the policies cover the loss – but because Montana recognizes coverage by estoppel, meaning the insurers are estopped to deny coverage when they failed to defend Stillwater in the appraisal action.

We affirm the Superior Court’s judgment. Before this Court issued its Solera II decision, the Superior Court in Solera I held that D&O insureds could recover losses incurred in a stockholder appraisal action. Taking advantage of the trial court’s favorable ruling, Stillwater argued that Delaware law applied to the interpretation of the policies. As it argued in its original complaint,

“Delaware law applies to the principles of contract interpretation at issue in this proceeding” and “Delaware has a strong interest in the application of its principles of corporate law and governance in construing the directors’ and officers’ liability insurance policies at issue in this matter.”1 After Solera II, however, Stillwater reversed position and claimed that Montana law applies to the policies. Its amended complaint dropped all indemnity claims for covered losses in favor of three contractual claims for the duty to advance defense costs and a statutory claim under Montana law. In our view, Stillwater’s amended claims raise the same Delaware interests that Stillwater identified in its original complaint – applying one consistent body of law to insurance policies that cover comprehensively the insured’s directors’, officers’, and corporate liability across many jurisdictions. Stillwater also challenges the Superior Court’s denials of its motion for voluntary dismissal without prejudice and its motion to stay pending resolution of the action Stillwater filed in Montana. The Superior Court did not exceed its discretion when it denied both motions.

I.

A.

Stillwater Mining Company is a Delaware corporation with its principal place of business in Stillwater County, Montana.2 Stillwater has directors’, officers’, and corporate liability insurance policies (the “D&O policies”) from National Union Fire Insurance Company (“NUFI”), as primary policy issuer, and ACE American Insurance Company and QBE Insurance Corporation, as excess insurers.3 We refer to the three defendants together as the “Insurers.”

The D&O policies provide that the Insurers “shall pay the Loss . . . arising from any Securities Claim made against [Stillwater] for any Wrongful Act.”4 The policies define “Loss” to include defense costs.5 The policies define a “Securities Claim” as “a Claim . . . alleging a violation of any law, rule or regulation, whether statutory or common law.”6 Under the policies, “Wrongful Act” means “any actual or alleged breach of duty, neglect, error, misstatement, misleading statement, omission or act by [Stillwater], but solely in regard to a Securities Claim.”7 The

2 Unless otherwise specified, the facts are drawn from the Superior Court’s opinion, Stillwater Mining Co. v. Nat’l Union Fire Ins. Co. of Pittsburgh, Pa., 2021 WL 6068046 (Del. Super. Dec. 22, 2021) [hereinafter Stillwater]. 3 The contract terms are from the primary policy. The excess policies are follow-form policies that incorporate the primary policy’s terms and conditions.

D&O policies do not require the Insurers to provide a defense in litigation but the Insurers “shall advance . . . covered Defense Costs” once they “received written notice of a Claim.”8 The D&O policies do not have a choice-of-law provision, but Stillwater emphasizes that they contain Montana amendatory endorsements, one of which provides for conformity with Montana law.9 Another Montana amendatory endorsement governing alternative dispute resolution states that “[t]he mediator or arbitrators shall give due consideration to the general principles of the law of the state where [Stillwater] is incorporated in the construction or interpretation of the provisions of this policy.”10 The policies afford coverage “anywhere in the world.”11 The D&O policies formed a tower of insurance that provided directors’, officers’, and corporate liability coverage for claims made during the policy period from May 1, 2016, to August 1, 2017.

Stillwater was publicly traded until 2017 when Sibanye Gold Limited, a South African mining company, acquired Stillwater in a merger and took it private. Following the merger, some Stillwater stockholders filed an appraisal action in the
