Each of the two grants covers 100,000 underlying shares of common stock. The options were awarded at a grant price of $0.00 with a $16.00 per-share exercise price, giving the CMO potential future ownership if vesting and exercise conditions are satisfied.

What are the time-based vesting terms of the KLRA stock options granted to the CMO?

One option grant vests 25% of its underlying shares on April 16, 2027. The remaining shares vest in 36 substantially equal monthly installments thereafter, so long as Scott M. Wasserman continues providing service through each applicable vesting date.

What performance conditions apply to the performance-based Kailera (KLRA) option grant?

The performance-based options vest only if the company’s stock reaches at least $40 per share. This can occur via a 30-day average daily closing price on Nasdaq or a qualifying change in control price during the October 16, 2026 to April 16, 2030 performance period.

When do the newly granted Kailera Therapeutics (KLRA) options expire?

Both stock option awards reported for Scott M. Wasserman have an expiration date of April 16, 2036. If the options are not exercised by that date, they will lapse, subject to earlier termination under standard employment or equity plan provisions described by the company.

Are the Kailera (KLRA) option awards to the CMO open-market purchases or compensation grants?
