FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What did Kailera Therapeutics (KLRA) disclose about CFO Douglas Pagan’s recent equity awards?

Kailera Therapeutics disclosed that CFO Douglas W. Pagan received two stock option grants, each covering 100,000 shares at a $16.00 exercise price. The options are compensation awards, not open-market purchases, and they expire on April 16, 2036, subject to specific vesting conditions.

How do the service-based stock options for KLRA’s CFO vest over time?

One 100,000-share stock option grant vests 25% on April 16, 2027, then in 36 substantially equal monthly installments. Vesting requires Douglas W. Pagan to remain in service through each vesting date, aligning his compensation with longer-term employment at Kailera Therapeutics.

What performance conditions apply to the KLRA CFO’s second stock option grant?

The second 100,000-share option grant vests only if the company’s stock price reaches $40 per share during a specified performance measurement period or in a qualifying change in control. Vesting also depends on Pagan’s continued service through the date the performance condition is met.

What is the performance measurement period for Kailera Therapeutics’ performance-based options?

The performance measurement period runs from October 16, 2026 to April 16, 2030. During this time, vesting of the performance-based options can occur if the average daily closing price hits $40 per share for 30 consecutive days or a qualifying change in control happens.

Are the reported KLRA stock option grants open-market insider purchases or sales?

The reported transactions are compensation-related option grants, not open-market buys or sells. They are recorded under code "A" for awards, giving the CFO rights to buy shares at $16.00 if the vesting and performance conditions described in the filing are satisfied over time.
