Footnotes
  1. F1 The restricted stock units ("RSU") were settled in shares of common stock per the terms of the award.
  2. F2 On May 12, 2026, the reporting person filed a Form 4 that inadvertently reported that he disposed of 90 RSUs and acquired 90 shares of Common Stock upon vesting of the RSUs. In fact, as reported in this amendment, the reporting person disposed of 140 RSUs and acquired 140 shares of Common Stock upon vesting of the RSUs. The original filing correctly reported the withholding of 50 shares of Common Stock to satisfy tax obligations arising from the settlement. This amendment also corrects the amounts of Common Stock and RSUs beneficially owned following the reported transactions to reflect the corrected transaction amounts.
  3. F3 Withholding of shares to satisfy tax liability on the vesting of the RSUs.
  4. F4 Each RSU represents a contingent right to receive one share of Stepan Company common stock.
  5. F5 Vests ratably over three years beginning on the date shown.
