Agreement and Plan of Merger regulatory

"This Form 4 reports securities disposed of under the Agreement and Plan of Merger (the "Merger Agreement"), entered into on March 2, 2026, by and among the Issuer, Stallion Intermediate Corporation ("Parent"), and Stallion MergerSub Corporation."

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.

restricted shares financial

"Immediately prior to the effective time of the merger, the Reporting Person contributed 40,000 restricted shares to Parent in exchange for an equivalent amount of shares restricted shares of Parent."

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.
