deferred stock units (DSUs) financial

"Issued as deferred stock units (DSUs) in connection with reporting person's retainer as a director"

Deferred stock units (DSUs) are a form of long-term pay that promises an employee or director future company shares or cash equal to the share value at a later date, usually after leaving the company or at a set vesting time. Think of them as a delayed paycheck tied to the stock: they align recipients’ interests with long-term share performance and matter to investors because they create potential future dilution and signal how management is rewarded and incentivized.

2023 Equity Incentive Plan financial

"in connection with reporting person's retainer as a director under the Company's 2023 Equity Incentive Plan"

Section 16(b) regulatory

"exempt from Section 16(b) by virtue of Rule 16b-3(d)(1) and (3)"

A federal rule that requires company insiders—like officers, directors and large shareholders—to return any profits made from buying and selling the company’s stock within a six-month window. It matters to investors because it discourages short-term trades that could exploit non-public information and helps protect outside shareholders by creating a simple, enforceable way to recover unfair gains, much like a rule stopping someone from flipping a limited-edition item for quick profit after getting early access.

Explanation of Responses:

1. Issued as deferred stock units (DSUs) in connection with reporting person's retainer as a director under the Company's 2023 Equity Incentive Plan and exempt from Section 16(b) by virtue of Rule 16b-3(d)(1) and (3). These DSUs are reportable, however, as directly owned shares of common stock, rather than as a derivative security in Table II, because any and all underlying DSUs are payable, at such time as they are to be settled, solely in common stock. See Lincoln National Corp. (March 20, 1992) (Q.3). The DSUs vest as follows: 1/4 on 8/31/2026, 1/4 on 11/30/2026, 1/4 on 2/28/2027 and 1/4 on 5/31/2027.
