MEMORANDUM OPINION

Date Submitted: December 9, 2025 Date Decided: March 17, 2026

Robert K. Beste, K&L GATES LLP, Wilmington, Delaware; Attorney for Plaintiff Armaments Research Company, Inc.

Dominick T. Gattuso & Elizabeth A. DeFelice, HEYMAN ENERIO GATTUSO & HIRZEL LLP, Wilmington, Delaware; Nathaniel J. Pencook, NELSON MULLINS RILEY & SCARBOROUGH LLP, Raleigh, North Carolina; Attorneys for Defendant William O’Neil

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.

1 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

1 Verified Am. and Suppl. Compl. Seeking Anti-Suit Inj. and Other Relief (Dkt. 13) (“Am. Compl.”); see Freedman v. Adams, 2012 WL 1345638, at *5 (Del. Ch. Mar. 30, 2012) (“When a plaintiff expressly refers to and heavily relies upon documents in her complaint, these documents are considered to be incorporated by reference into the complaint . . . .”). The paragraphs in the Complaint are misnumbered; citations to the Complaint reflect the paragraph numbers included in the document. 2 Am. Compl. ¶ 1. 3 Id. ¶ 2. 4 Id. ¶¶ 3-4. 5 Id. ¶ 9.

2 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

6 Id. ¶ 9. 7 Id. at Ex. 2 (“Separation Agreement”) § 18. 8 Id. § 6. 9 Id. § 6(b); see also Am. Compl. ¶ 14. 10 Separation Agreement § 6(a). 11 Id. § 6(a), (c). 12 Id. § 6(c); see also Am. Compl. ¶ 15.

3 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

13 Separation Agreement § 6(d). 14 Id. § 6(a). 15 Am. Compl. Ex. 3 (Amendment to Separation Agreement) § 1; see also Am. Compl. ¶ 17. 16 Am. Compl. ¶ 19. 17 Id. at Ex. 1 (“Stock Repurchase Agreement”) § 11; Am. Compl. § 20. 18 Am. Compl. Ex. 4 (“Note”); Stock Repurchase Agreement § 1; see also Am. Compl. ¶ 21.

4 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

19 Stock Repurchase Agreement Ex. B. 20 Stock Repurchase Agreement § 7(a) (“[T]he Seller . . . irrevocably and unconditionally forever discharges, acquits and releases the Company . . . from all rights, claims . . . arising directly or indirectly out of [] an investment in, ownership of, and the sale of the Shares . . . .”). 21 Id. § 11. 22 Am. Compl. ¶ 21. 23 Id. ¶ 22.

5 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,
