Insights

Form 4 shows award forfeitures on termination and routine tax withholding, not market selling.

The filing shows Samantha Jacobson, a director and Chief Strategy Officer at Trade Desk, Inc., returning 258,158 Class A shares to the issuer on May 18, 2026. Code "D" and footnotes indicate these shares were unvested restricted stock and restricted stock units forfeited upon her termination of employment.

Earlier, on May 15, 2026, 6,673 shares were withheld at $21.15 per share under code "F" to cover tax obligations triggered by partial vesting of multiple equity awards. These are non-market, administrative events rather than discretionary buys or sells. She still directly holds 318,937 shares after the transactions, so her equity exposure remains substantial despite the forfeitures.

Restricted Stock Unit Award financial
"The shares were withheld ... in connection with the partial vesting of a Restricted Stock Unit Award granted April 26, 2022."
A restricted stock unit award is a promise by a company to give an employee a specified number of company shares at a future date if certain conditions are met, such as staying with the company or hitting performance goals. For investors, these awards matter because they can increase the total number of shares outstanding when converted, diluting existing holders, and they align employees’ incentives with shareholders’ interests much like giving a rising bonus that becomes real only after conditions are satisfied.
Restricted Stock Award financial
"The shares were withheld ... in connection with the partial vesting of a Restricted Stock Award granted April 23, 2024."
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
"Includes 622 shares acquired through the Employee Stock Purchase Plan on May 15, 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.
