Insights

Equity compensation analyst

CEO executed a modest open-market sale while retaining a sizable equity stake and unexercised options.

Charles M. Shaffer sold 10,367 Seacoast Banking common shares at a weighted average of $30.88, with trade prices between $30.75 and $30.96. Following the sale, he directly held 174,113 common shares, so the transaction represents only a small portion of his visible equity position.

Shaffer also retained stock options covering 18,952 shares at $31.15 expiring on April 1, 2028, and 28,544 shares at $28.69 expiring on April 1, 2027. Footnotes describe additional unvested restricted stock and plan-based holdings, underscoring that a substantial part of his compensation remains equity-linked.

Overall, this looks like a routine liquidity event rather than a transformational change in insider ownership. Future company filings may provide further context on how his remaining options and restricted awards vest over time and align incentives with long-term performance.

Key Terms

6 terms

weighted average price financial

"The price reported in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

restricted stock units financial

"Represents unvested time based restricted stock units granted on April 15, 2026, which vests over 3 years"

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.

restricted stock award financial

"Represents an unvested time-based restricted stock award granted on April 1, 2024, which shall vest over 3 years"

A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.

Employee Stock Purchase Plan financial

"Shares in the Company's Employee Stock Purchase Plan, as of March 31, 2026"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

Retirement Savings Plan financial

"Share equivalents held in Company's Retirement Savings Plan as of March 31, 2026"

Incentive Plan financial

"Granted pursuant to the Company's Amended and Restated 2013 Incentive Plan."
