Kalowski Lee 4

What Happened

• Kalowski Lee, CFO and President of Q32 Bio Inc. (QTTB), was granted 53,250 restricted stock units (RSUs) on February 24, 2026. The award was recorded at $0.00 per RSU (no cash paid on grant). Each RSU represents a contingent right to receive one share of Q32 Bio common stock upon vesting.

Key Details

• Transaction date: 2026-02-24. Filing date: 2026-03-20 (the filing appears late relative to the typical 2-business-day Form 4 deadline).
• Grant details: 53,250 RSUs granted at $0.00 per unit; total immediate cash value reported as $0.
• Shares owned after transaction: not specified in the information provided.
• Footnote (vesting schedule): RSUs vest in four equal installments — 25% at 6 months from the grant date (Aug 24, 2026), 25% at 12 months, 25% at 24 months, and 25% at 36 months. Each vested RSU converts to one share.
• No 10b5-1 plan, tax-withholding sale, or immediate sale of shares was reported in the provided filing.

Context

• This is an equity award (grant) rather than a market purchase or sale. RSU grants align executive compensation with future company performance and do not represent immediate sale proceeds. The vesting schedule means the shares will be delivered over three years if vesting conditions are met. The late filing date may be noted by investors and compliance observers, as Form 4s are normally due within two business days of the transaction.
