Agreement and Plan of Merger financial

"pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated as of January 11, 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.

First Merger financial

"Merger Sub 1 merged with and into Sun Country (the "First Merger"), with Sun Country surviving"

Second Merger financial

"Sun Country merged with and into Merger Sub 2, with Merger Sub 2 surviving ... (the "Second Merger")"

Merger Consideration financial

"the "Per Share Stock Consideration" and, together with the Per Share Cash Consideration, the "Merger Consideration""

Merger consideration is the total payment a company or buyer offers to shareholders of a target company in exchange for combining the two businesses, and can include cash, shares in the surviving company, debt assumption, or a mix of these. Investors care because the form and amount affect the deal’s value, tax consequences, immediate cash received versus future ownership, and the risk and upside of holding new shares — similar to choosing between cash now or stock that could grow later.

Company RSU Award financial

"each outstanding Sun Country restricted stock unit award ("Company RSU Award") consisting of 10,390 restricted stock units"
