5 terms

Agreement and Plan of Merger regulatory

"On May 7, 2026, pursuant to the Agreement and Plan of Merger entered into on February 1, 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.

wholly owned subsidiary financial

"...Coterra became a wholly owned subsidiary of Devon."

A wholly owned subsidiary is a company whose entire ownership is held by another company (the parent), so the parent controls decisions, operations, and finances. Think of it as a fully controlled branch that runs as its own legal entity but whose results flow straight into the parent’s financial statements; investors watch these structures because they affect consolidated revenue, risk exposure, and how profits, liabilities, and cash flow are allocated across the corporate group.

restricted stock unit financial

"each time-based Coterra restricted stock unit ("Coterra RSU") outstanding and unvested..."

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

performance stock units financial

"These Devon RSUs relate to an award of Coterra performance stock units (a "Coterra PSU Award")..."

Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.

target level financial

"...was deemed earned at 100% of the target level as a result of the certification..."
