Jackson Mary M. 4

What Happened

• Mary M. Jackson, a director of Custom Truck One Source, had restricted stock units (derivatives) that vested and were converted into 26,859 shares on March 31, 2026 (reported as an exercise/conversion, code M) at $0.00 per share. Immediately the derivative instrument was shown as disposed (derivative cancelled) as part of the conversion. On April 1, 2026 she was granted 19,225 restricted stock units (code A) at $0.00. These transactions reflect vesting/conversion and a subsequent equity award as part of compensation — not an open-market purchase or sale.

Context

• These entries reflect typical equity compensation actions: vested RSUs converting into common shares (a non‑cash event) and a subsequent award of new RSUs. Such compensation-related conversions and grants are common for directors and do not, by themselves, indicate a buy or sell signal in the market.
