2024 Incentive Stock and Awards Plan financial

"Common Stock granted to Reporting Person pursuant to the Company's 2024 Incentive Stock and Awards Plan."

deferred shares financial

"The amount beneficially owned includes deferred shares acquired pursuant to dividend reinvestments"

Deferred shares are a class of stock whose economic benefits or certain shareholder rights are delayed or paid later than ordinary shares—for example, dividends may be paid only after other shareholders receive theirs, or voting or redemption rights may be postponed. For investors, that timing difference matters because deferred shares typically offer lower near-term income and different risk, affecting expected returns, priority in payouts, and the share’s market value; think of them like a delayed paycheck compared with a regular salary.

dividend reinvestments financial

"deferred shares acquired pursuant to dividend reinvestments in exempt transactions"

Section 16(a) regulatory

"exempt transactions not required to be reported pursuant to Section 16(a)."
