Argus Roger R 4

What Happened

• Roger Argus, President and CEO of Tetra Tech (TTEK), received a grant of 28,174 restricted stock units (RSUs) on February 19, 2026. The reported acquisition price is $0.00 because this is an equity award (transaction code A) rather than a cash purchase. The RSUs are a derivative award that convert into shares when they vest.

Key Details

• Transaction date: February 19, 2026; Form 4 filed February 20, 2026 (timely filing).
• Award size: 28,174 RSUs; reported acquisition price $0.00 (derivative award).
• Vesting: 25% vests on February 19, 2027, and 25% annually thereafter until fully vested (Footnote F2).
• Exercisability/Expiration: RSUs become exercisable upon vesting and have no set expiration date (Footnote F3).
• Shares owned after transaction: not reported in the Form 4 filing.
• Transaction type: Grant/award of RSUs (derivative), not a market purchase or sale.

Context

• RSU grants are common as part of executive compensation and align long-term incentives; because these are awards (not purchases or sales), they do not directly indicate the insider buying or selling stock.
• The award vests over multiple years, so the economic benefit depends on future vesting and the company’s share price at vesting.
