WILL, Vice Chancellor

In 2021, Armaments Research Company, Inc. and its co-founder William O’Neil signed a Separation Agreement establishing a process to value and repurchase O’Neil’s equity. They later signed a Stock Repurchase Agreement to effect that transfer. Three years later, the parties disputed a contractual price adjustment.

O’Neil sued in North Carolina under the Separation Agreement. Armaments sued here, seeking an anti-suit injunction based on a Delaware forum selection clause in the Stock Repurchase Agreement. O’Neil now moves to dismiss Armaments’ lawsuit.

Armaments’ action rests on the flawed premise that the Stock Repurchase Agreement extinguished the Separation Agreement. Because O’Neil’s claims arise under the Separation Agreement, he did not breach the forum selection clause by suing in North Carolina. Armaments’ claim for breach of the Stock Repurchase Agreement is dismissed with prejudice.

As for the remaining declaratory judgment claim, I decline to exercise jurisdiction. The claim can be fully resolved in the pending North Carolina action and is overripe. It is therefore dismissed without prejudice.

I. BACKGROUND Unless otherwise noted, the following facts are drawn from the Verified Amended and Supplemental Complaint (the “Complaint”) and the documents it incorporates by reference.1 A. The Separation Agreement Armaments Research Company, Inc. is a Delaware corporation with its principal place of business in Bethesda, Maryland.2 It is a technology company developing hardware and software for artificial intelligence-enabled weapons sensors that support large-scale combat operations.3 William O’Neil, formerly known as William Deng, is a co-founder of Armaments who resides in North Carolina.4 On June 15, 2021, Armaments and O’Neil entered into a Separation Agreement to sever their relationship.5 According to Armaments, its technology

development was beginning to outpace O’Neil’s skillset.6 The Separation Agreement is governed by North Carolina law.7 Under the Separation Agreement, the parties agreed to a process for Armaments to repurchase O’Neil’s shares.8 Moss Adams LLP, an independent valuation firm, would calculate the share value.9 The parties would then mutually agree to one of two repurchase options within ten days after the price was determined.10 The first option called for Armaments to repurchase the equivalent of 3,900,000 shares of O’Neil’s common stock in exchange for a promissory note.11 The note would be due at the earlier of five years after the separation date, June 15, 2026, or the closing of a bona fide acquisition of Armaments.12 If the note remained

unpaid by June 15, 2024, the parties agreed to adjust the purchase price by applying a new per-share value determined by a second Moss Adams valuation.13 The Separation Agreement contemplated that the parties would enter into a later, binding agreement relating to Armaments’ acquisition of O’Neil’s stock once the price was determined.14 B. The Stock Repurchase Agreement On August 10, 2021, the parties amended the Separation Agreement to extend the initial valuation date to August 24, 2021.15 On August 25, Moss Adams presented its valuation to Armaments. It concluded that the fair market value of one share of Armaments common stock (on a minority, non-marketable basis) was $0.154.16 On September 28, the parties executed a Stock Repurchase and Transaction Bonus Cancellation Agreement (the “Stock Repurchase Agreement”), which is governed by Delaware law.17 To satisfy the aggregate purchase price of $354,199.85, Armaments delivered to O’Neil a promissory note (the “Note”).18 In connection

with the Stock Repurchase Agreement, O’Neil executed a stock assignment transferring 2,299,999 of his shares of common stock to Armaments.19 The Stock Repurchase Agreement contains a “Release and Waiver” provision in which O’Neil released Armaments from all claims “arising directly or indirectly out of” an “investment in, ownership of, and the sale of” his shares.20 The parties also agreed that any action “brought by either party under or in relation to” the Stock Repurchase Agreement would be submitted to the exclusive jurisdiction and venue of Delaware courts.21 C. The Second Valuation As of June 15, 2024, Armaments had not repaid the Note.22 On June 17, it proposed that the parties forgo the 2024 valuation required by the Note, but O’Neil refused.23 As a result, under Section 3 of the Note, Moss Adams began a new

valuation “in a manner substantively consistent with the valuation process set forth in Section 6(b) of the Separation Agreement.”24 On July 19, 2024, Moss Adams completed the second valuation, calculating a new per-share fair market value of $0.08.25 O’Neil disputed this valuation, arguing that the methodology did not represent fair market value.26 Moss Adams provided further explanations, but O’Neil was not swayed.27 O’Neil insisted the shares be valued based on the company’s enterprise value.28 He also accused Armaments of pursuing the valuation independently, despite a purported requirement to include him.29 Armaments, however, maintained that the valuation properly followed the Note and Stock Repurchase Agreement, which required applying a discount for lack of control and lack of marketability.30

Armaments also expressed a willingness to commission another valuation to address O’Neil’s objections.31 D. The Lawsuits
