Koppers (KOP) CEO LeRoy Ball Vests PSUs, Surrenders 22,236 Shares

What Happened

LeRoy Ball, CEO and Director of Koppers Holdings (KOP), had performance share units (PSUs) and related dividend equivalent rights (DERs) vest on Feb 26, 2026. As a result he was issued 50,025 shares (award) and additional DER-related shares (1,215 reported). To satisfy tax withholding on the vesting, Ball surrendered 22,236 shares to the issuer at $37.24 per share, generating proceeds/withholding of $828,069. Several derivative-related entries reflect the conversion/release of DERs and PSU settlement; the awarded shares show $0 acquisition price because they were compensation awards.

Key Details

Transaction date: 2026-02-26; Form 4 filed 2026-03-02 (no late-filing flag noted).
Awarded/issued: 50,025 shares (award) and 1,215 DER/related shares (reported as acquisitions at $0).
Disposed/surrendered for tax withholding: 22,236 shares at $37.24 each = $828,069 (code F — tax withholding).
Derivative actions: entries coded M/A reflect conversion/exercise or release of dividend equivalent rights tied to PSUs.
Shares owned after the transactions: not specified in the provided filing details.
Footnotes: PSUs were originally granted Jan 4, 2023 (performance period 2023–2025); DERs are the economic equivalent of one share and were released on vesting; surrendered shares were used to pay tax withholding.

Context

These transactions are compensation-related (PSU vesting and DER releases), not an open-market purchase or indicative "buy" signal. Surrendering shares to cover taxes on vested awards is a routine administrative action and does not by itself indicate the insider’s view of the stock.
For retail investors: awards increase insider-held shares but some were immediately surrendered for taxes; derivative entries mean rights tied to the PSUs were converted into shares upon vesting.
