Arnold Mark L. 4

What Happened

• Mark L. Arnold, President (Rasmussen) of American Public Education, Inc. (APEI), received a grant of 4,617 restricted stock units (RSUs) (reported as an acquisition) on 2026-02-02. The award has a $0.00 per-share acquisition price (standard for RSU grants).
• On 2026-01-30 the company withheld 903 shares from Arnold to satisfy tax withholding obligations tied to RSU vesting. Those 903 shares were disposed at $41.78 per share, generating $37,727. This withholding is a routine tax-related disposition (transaction code F), not an open-market sale.

• Vesting: RSUs granted under the American Public Education, Inc. 2017 Omnibus Incentive Plan; vest in three equal annual installments beginning on the first anniversary of the grant (footnote F2).
• Tax withholding: The 903-share disposition reflects shares withheld by the issuer to pay tax withholding on RSU vesting (footnote F1).

Context

• RSU grants are compensation and represent future share delivery as they vest; the grant is an acquisition of rights to shares, not an immediate open-market purchase. Withholding shares to cover taxes is a common, routine issuer action and does not necessarily indicate a voluntary sale by the insider.
• For retail investors, new RSU grants signal ongoing executive compensation alignment with company performance, while the withheld shares are an administrative tax event rather than a market-driven sale.
