HELT JAMES 4

What Happened

Key Details

• Transaction date: March 13, 2026; Form 4 filed March 17, 2026 (timely filing).
• Award details: 8,419.431 restricted shares @ $46.42 = $390,830.
• Tax withholding: 799.565 shares withheld @ $46.42 = $37,116 (shares withheld, not sold).

Context

• This was a compensation award (restricted stock) rather than an open-market purchase or sale. The immediate withholding to cover taxes is a common administrative step and does not indicate a market sale of shares. The filing notes the execution date and withholding per SEC rules; no sale of shares by the insider was reported.
