4 terms

Agreement and Plan of Merger financial

"In connection with the terms of an Agreement and Plan of Merger, dated November 16, 2025"

An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.

Merger Sub financial

"Sword Merger Sub, Inc., a wholly owned subsidiary of Sword ("Merger Sub"), Merger Sub merged with and into the Issuer"

A merger sub is a temporary, wholly owned subsidiary that an acquiring company creates to carry out a merger with another firm. Think of it as a wrapper used to combine two businesses—this can simplify legal and tax steps, isolate liabilities, and help preserve the target’s contracts or stock structure, so investors watch it because the chosen approach affects deal mechanics, shareholder votes, potential dilution, and legal or tax risk.

Effective Time financial

"with the Issuer surviving as a wholly owned subsidiary of Sword (the "Effective Time"). At the Effective Time, each outstanding share"

Disposition to issuer financial
