Agreement and Plan of Merger regulatory
"Disposed of pursuant to the Agreement and Plan of Merger, dated December 29, 2025, by and among Issuer, OceanFirst Financial Corporation (OCFC), and Apollo Merger Sub Corp."
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 Consideration financial
"each share of Issuer common stock issued and outstanding ... was converted into the right to receive 0.85 shares of OCFC common stock (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.
restricted stock units financial
"Represents previously unvested Issuer RSUs and Issuer PRSUs awarded prior to the date of the Merger Agreement that ... were accelerated and vested."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
performance restricted stock units financial
"Represents previously unvested Issuer RSUs and Issuer PRSUs awarded after the date of the Merger Agreement that ... were converted into service-based RSUs."
Performance restricted stock units (PRSUs) are promises to deliver company shares to employees or executives only if the business meets specific performance targets and any time-based holding rules. Think of them as a bonus that converts into stock only after set goals are reached, so investors watch PRSUs for two reasons: they can dilute existing shares if paid out, and they signal how closely management’s pay is tied to company performance.
401(k) Savings Plan financial
"Consists of shares of Issuer common stock credited to the Reporting Person 401(k) account at the Issuer 401(k) Savings Plan."
A 401(k) savings plan is an employer-sponsored retirement account that lets employees set aside a portion of their paycheck on a tax-advantaged basis, often with employer matching contributions that act like free additional savings. It matters to investors because matching, tax-deferred growth and investment choices can significantly boost long-term wealth—while plan rules or heavy concentration in a single company’s stock can increase an employee’s financial exposure to that company.
