Packaging Corp (PKG) SVP Olivier Darla Receives Award, 559 Shares Withheld

What Happened
Olivier Darla, Senior Vice President at Packaging Corporation of America (PKG), received a payout of performance units that vested on March 6, 2026 — 1,182 shares from the ROIC performance units and 104 shares representing accumulated dividends, for a total of 1,286 shares granted at $0.00. To satisfy withholding tax obligations under the company plan, the company withheld/disposed 559 of those shares at $222.52 each, yielding proceeds of $124,389. The primary event is an award/vesting (A); the share disposition (F) was tax withholding, not a market sale for cash proceeds beyond covering taxes.

Context
This was a vesting of performance-based equity (not an open-market purchase or voluntary sale). The 559-share disposition was a routine share-withholding to cover taxes under the company’s long-term equity incentive plan (a cashless tax-withholding mechanism), so it should not be read as a directional market bet by the insider.
