3 terms

Agreement and Plan of Merger financial

"Agreement and Plan of Merger, dated May 4, 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.

cash consideration financial

"right to receive $17.25 cash consideration"

Cash consideration is the actual money paid to buy a company, asset, or stake rather than payment in shares or other forms. For investors it matters because cash payments deliver immediate, certain value and affect the buyer’s and seller’s cash reserves and balance sheets—like selling a car for cash versus taking a trade-in, one side gets instant spending power while the other changes its liquidity and risk profile.

exercise price financial

"less the exercise price of such option"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
