FAQ

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

What equity awards did Longeveron (LGVN) CEO Willard Stephen H receive?

The CEO received a 200,000-share stock option at $0.545, a 200,000-share initial hire award of Class A common stock, and 200,000 time-based vesting RSUs. These grants significantly increase his equity-based compensation and align pay with Longeveron’s share performance over time.

How do the new stock options for Longeveron (LGVN) CEO vest?

The 200,000-share stock option granted to the CEO vests quarterly over a four-year period beginning on April 1, 2026. This schedule encourages longer-term retention and performance, as the full option benefit is realized only if he remains with Longeveron over that period.

Were any Longeveron (LGVN) shares sold in this Form 4 filing?

No open-market sales were reported. Instead, 105,533 shares of Class A common stock were withheld to satisfy tax obligations related to the initial hire stock award. This tax-withholding disposition is a standard mechanism and does not represent a discretionary sale into the market.

How many Longeveron (LGVN) shares does the CEO hold after these awards?

After the reported equity grants and tax withholding, the CEO directly holds 294,467 shares of Class A common stock. This figure includes RSUs that are still subject to future vesting, reflecting both currently owned and time-based restricted equity positions.

What is the significance of the RSU award to the Longeveron (LGVN) CEO?

The CEO received 200,000 time-based vesting RSUs, which convert into Class A common stock as they vest. RSUs typically encourage executives to focus on long-term company performance, since their value depends on both vesting conditions and future Longeveron share prices.
