Reitemeier Christophe 4

What Happened

• Christophe Reitemeier, President—Harsco Environmental, had 2,498 restricted stock units (RSUs) convert into Enviri common shares on 2026-03-07. The RSU conversion shows an exercise/conversion at $0 (typical for RSUs) and 1,175 of the resulting shares were withheld to cover tax withholding, valued at $17.65 each for a total withholding value of $20,739. Net shares delivered to Reitemeier were 1,323 (2,498 converted minus 1,175 withheld).

Key Details

• Transaction date: 2026-03-07; Form filed: 2026-03-10 (appears timely).
• Conversion: 2,498 RSUs converted (transaction code M) at $0 exercise price.
• Tax withholding: 1,175 shares withheld (transaction code F) at $17.65/share = $20,739.
• Net shares received: 1,323 (noted from conversion minus withholding).
• Footnote: These were restricted stock units under the 2013 Equity and Incentive Compensation Plan; RSUs vest in one-third increments (F1).
• Shares owned after transaction: not disclosed in the provided excerpt.

Context

• This was a vesting/conversion of RSUs rather than an open-market purchase or sale. Withholding shares to cover taxes is a routine administrative step (similar to a cashless settlement) and does not by itself indicate a buy or sell decision by the insider. Transaction codes: M = exercise/conversion of derivative (RSU conversion here); F = shares withheld to satisfy tax obligations.
