Xu Kang 4

What Happened

• Xu Kang, Chief Technology Officer of SES AI Corp (SES), was granted 221,239 restricted stock units (RSUs) on May 18, 2026. The grant is reported as an acquisition at $0.00 (no cash paid). The RSUs will convert into the same number of Class A common shares as they vest.

Key Details

• Transaction date and price: May 18, 2026; grant recorded at $0.00 per share (reported acquisition value $0). Filing date: May 20, 2026.
• Vesting: The RSUs vest in three equal installments on the first, second and third anniversaries of the May 18, 2026 grant date, subject to continued employment (per footnote F1).
• Existing RSUs: The filing notes 537,894 shares of Class A common stock are already subject to outstanding RSUs and remain subject to forfeiture until they vest (per footnote F2).
• Timeliness: Form 4 was filed May 20, 2026 for a May 18 transaction—this appears to be a timely Form 4 filing (Form 4 is generally due within two business days).

Context

• This was an equity award (grant of RSUs), not a market purchase or sale, so it reflects a compensation/retention action rather than an immediate investment or liquidity event. RSUs do not transfer marketable shares to the insider until they vest; therefore these grants do not by themselves indicate immediate buying or selling pressure.
