Context

• This was a compensation grant (restricted stock) with a one‑year restriction/vesting period; such awards are common for directors and do not by themselves indicate a buy/sell market signal.
• The grant value shown on the Form 4 is $0 because it reports the grant price; the market value would depend on KALU’s stock price and is not stated in the filing.
