("Parent"), Onyx MergerSub, Inc., a wholly owned subsidiary of Parent ("Obsidian Merger Sub"), and Gazelle Merger Subsidiary, Inc., a wholly owned subsidiary of Parent ("Galera Merger Sub"), on August 3, 2026, Galera merged with and into Galera Merger Sub, with Galera surviving as a wholly owned subsidiary of Parent (the "Galera Merger"), and Obsidian merged with and into Obsidian Merger Sub, with Obsidian surviving as a wholly owned subsidiary of Parent (together with the Galera Merger, the "Mergers").
- F3.

"adjusted to reflect the 1-for-200 reverse stock split Galera Therapeutics, Inc. effected"
Agreement and Plan of Merger regulatory
"Pursuant to an Agreement and Plan of Merger, dated as of April 14, 2026"
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.
In-the-Money Option financial
"each outstanding Galera stock option with an exercise price per share less than $15.62 (each, an "In-the-Money Option")"
Galera Exchange Ratio financial
"was converted into the right to receive 0.7019 shares of Parent common stock (the "Galera Exchange Ratio")"
withholding taxes financial
"subtracting the number of shares of Parent common stock with a value equal to the exercise price and withholding taxes"
Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.
