Aclaris CBO reports RSU vesting, tax withholding

Aclaris Therapeutics, Inc.'s Chief Business Officer reported multiple equity compensation events on February 1, 2026.

Rhea-AI Filing Summary

Aclaris Therapeutics, Inc.'s Chief Business Officer reported multiple equity compensation events on February 1, 2026. Several restricted stock unit (RSU) awards were exercised (transaction code M), delivering 11,250, 7,500, and 14,750 shares of common stock in separate transactions.

The filing also reports a transaction coded F, where 10,686 shares were withheld at $3.51 per share to cover tax obligations tied to RSU vesting. The RSU grants vest in four equal annual installments starting on February 1 of 2022, 2023, and 2024, subject to continued service. This amendment corrects a prior filing that mistakenly referenced a February 1, 2025 transaction due to a filing platform error.

FAQ

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

What insider activity did Aclaris Therapeutics (ACRS) report in this Form 4/A?

The filing reports the Chief Business Officer’s restricted stock units converting into common stock and related tax share withholding on February 1, 2026. Multiple RSU tranches vested and were settled in shares, with some shares withheld to satisfy tax obligations.

Who is the reporting person in this Aclaris Therapeutics (ACRS) Form 4/A?

The reporting person is Aclaris Therapeutics’ Chief Business Officer, identified as an officer of the company. The individual reports beneficial ownership of common stock directly, reflecting changes from RSU vesting and tax share withholding on February 1, 2026.

What RSU-related stock transactions occurred on February 1, 2026 for ACRS?

On February 1, 2026, three RSU awards were exercised, delivering 11,250, 7,500, and 14,750 Aclaris common shares in separate transactions. These events are coded M, showing conversions from RSUs into common stock at a stated exercise price of $0 for the derivative securities.

Why were 10,686 Aclaris (ACRS) shares withheld in this insider filing?

The filing shows 10,686 shares withheld at $3.51 per share, coded F, to satisfy the reporting person’s tax withholding obligations. This withholding is tied to the vesting and settlement of RSUs and reduces the net shares delivered to the officer.

What vesting schedules apply to the Aclaris (ACRS) RSUs in this Form 4/A?

The RSUs vest in four equal annual installments on the first through fourth anniversaries of February 1, 2022, 2023, and 2024. Vesting is subject to the officer’s continuous service under the company’s plan as of each applicable anniversary date.

Why was the original Aclaris (ACRS) Form 4 amended and restated?

The amendment states the prior Form 4, filed February 3, 2026, erroneously reported a February 1, 2025 transaction. The error arose from the filing platform, so this Form 4/A corrects the transaction date to February 1, 2026 and restates the details.
