Agreement and Plan of Merger regulatory

"pursuant to, the transactions contemplated by the Agreement and Plan of Merger, dated as of August 7, 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 Agreement regulatory

"Horizon Technology Finance Management LLC, a Delaware limited liability company (the "Merger Agreement")"

A merger agreement is a binding contract that lays out the exact terms for two companies to combine, including the price, what each side will deliver, and the conditions that must be met before the deal is completed. Investors care because it sets the timetable, payouts and risks — like a blueprint or prenup that shows whether the deal is likely to close, how ownership will change, and what could cancel or alter the payout they expect.

converted into the right to receive financial

"each share of MRCC common stock, par value $0.001 per share, was converted into the right to receive 0.9402 shares of HRZN common stock"

par value financial

"MRCC common stock, par value $0.001 per share, was converted into the right to receive 0.9402 shares of HRZN common stock, par value $0.001 per share"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

Common Stock financial

"security_title": "Common Stock""

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
