restricted stock units financial

"restricted stock units with respect to the Issuer's common stock"

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.

dividend equivalent right financial

"Each dividend equivalent right entitles the reporting person to receive one share"

quarterly cash dividend financial

"declared a quarterly cash dividend in the amount of $0.15 per share"

A quarterly cash dividend is a payment made by a company to its shareholders four times a year, usually based on its profits. It is like a regular bonus or reward for owning the company's stock, providing shareholders with income. Many investors see these payments as a sign of the company's stability and its ability to generate consistent profits.

Rule 16b-3 regulatory

"The grant of dividend equivalent rights was approved ... pursuant to Rule 16b-3"

Rule 16b-3 is a Securities and Exchange Commission regulation that exempts certain routine, pre-approved transactions by company insiders from automatic liability for short-term trading profits. It acts like a safe harbor: if an insider follows a formal plan or the board approves specific transactions in advance, profits from buying and selling company stock within six months are not automatically reclaimed. Investors care because the rule clarifies when insider trades are permissible and reduces uncertainty about potential clawbacks.

Explanation of Responses:

1. On March 5, 2026, the Issuer's board of directors declared a quarterly cash dividend in the amount of $0.15 per share of its common stock, payable on March 31, 2026 to stockholders of record of the common stock at the close of business on March 16, 2026 (the "Dividend"). The amount acquired in column 4 represents equivalent rights accrued as a result of the Dividend on restricted stock units with respect to the Issuer's common stock ("Original RSUs") held by the reporting person. Each dividend equivalent right entitles the reporting person to receive one share of the Issuer's common stock upon the settlement of the Original RSUs and is subject to the same terms and conditions, including vesting and settlement, as the Original RSUs to which it relates. The grant of dividend equivalent rights was approved by the Issuer's board of directors pursuant to Rule 16b-3 of the Securities Exchange Act of 1934, as amended.
