What Happened

Narayan Vijai, VP, Corporate Controller & CAO of Kaiser Aluminum, was granted 733 restricted stock units (RSUs) effective March 5, 2026. The RSUs carry no immediate cash price and restrictions generally lapse on March 5, 2029.

Context

RSU grants are compensation awards that vest over time — they are not purchases and do not necessarily signal a buy/sell opinion. The share disposals reported here are tax-withholding transactions (common when RSUs vest) rather than discretionary market sales.
This filing reports an award plus routine withholding to cover taxes; no 10b5-1 plan or late filing was indicated in the provided details.
