Key Details

• Transaction date: 2026-05-21; Form 4 filed: 2026-05-26 (filed one business day after the typical two-business-day Form 4 deadline).
• Grant: 4,024 RSUs @ $0.00 (derivative award).
• Shares owned after transaction: not disclosed in the provided filing.
• Footnote: RSUs were granted under the Fifth Amended and Restated Trinity Industries, Inc. 2004 Stock Option and Incentive Plan. Units vest on the first annual stockholders meeting following the grant date; distribution is 1-for-1 in Trinity common stock after the director’s termination.

Context RSUs are a form of equity compensation that convert into shares under specified conditions (vesting and distribution). This award is a grant (not a market purchase or sale) and therefore does not by itself indicate immediate buying or selling activity by the insider. The filing was submitted after the usual two-business-day reporting window, which may be treated as a late filing under SEC Form 4 timing rules.
