Incentive Stock Option financial

"Represents stock options (the "Options") granted pursuant to the Issuer's Amended and Restated 2019 Omnibus Equity Incentive Plan"

An incentive stock option is a type of employee benefit that gives a worker the right to buy company shares at a fixed price, with special tax advantages if the employee holds the shares for a required period. Think of it as a coupon to buy future shares at today’s price that can result in lower tax on the gain. Investors care because ISOs can dilute share count, align staff incentives with the stock price, and affect company compensation costs and the timing of potential share sales.

Non-Qualified Stock Option financial

"Non-Qualified Stock Option (right to buy)"

A non-qualified stock option (NSO) is a contract that lets an employee or service provider buy company shares at a fixed price for a set period, like a voucher to purchase stock later at today’s price. It matters to investors because exercising NSOs creates ordinary income for the holder and can increase share count, affecting a company’s earnings and ownership mix; think of it as a future sale that can dilute existing shareholders and has immediate tax consequences for the recipient.

Amended and Restated 2019 Omnibus Equity Incentive Plan financial

"granted pursuant to the Issuer's Amended and Restated 2019 Omnibus Equity Incentive Plan, as amended"

vesting financial

"25% of the Options will vest on the six-month anniversary"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

Grant Date financial

"six-month anniversary of April 7, 2026 (the "Grant Date")"

The grant date is the day a company formally gives an employee or contractor the right to receive stock-based compensation, such as stock options or restricted shares. It matters to investors because it fixes key terms—like the price, the start of the ownership clock, and when the award will affect the company’s financial statements and share count—so it can influence dilution, reported expenses, and potential future selling pressure.

FAQ

What did Vistagen (VTGN) report in this Form 4 filing?

Vistagen reported stock option grants to its Chief Legal Officer, Reid G. Adler. He received incentive and non-qualified options linked to common stock as equity compensation, with a fixed exercise price and multi-step vesting schedule over two years following the April 7, 2026 grant date.

How many Vistagen (VTGN) options were granted to the Chief Legal Officer?

Reid G. Adler received 18,753 Incentive Stock Options and 56,247 Non-Qualified Stock Options. Both option grants relate to Vistagen common stock and represent equity-based compensation rather than cash, aligning part of the executive’s pay with future share performance.

What is the exercise price of the Vistagen (VTGN) options granted?

Both the Incentive Stock Option and the Non-Qualified Stock Option were granted with an exercise price of $0.5358 per share. This price is what the executive must pay per share to acquire Vistagen common stock upon exercising the options before their expiration date.

When do the new Vistagen (VTGN) option grants vest for the Chief Legal Officer?

The options vest over two years from the April 7, 2026 grant date. Twenty-five percent vests on the six-month anniversary, and additional 25% portions vest every six months thereafter, so the grants become fully vested on the two-year anniversary of the grant date.

When do the Vistagen (VTGN) options granted to Reid G. Adler expire?

Both the Incentive Stock Option and the Non-Qualified Stock Option expire on April 7, 2036. The executive must exercise any vested portions before that expiration date to purchase common shares at the fixed exercise price disclosed in the Form 4 filing.

Is this Vistagen (VTGN) Form 4 filing a market buy or sell by the insider?

No, this filing reflects equity awards rather than market trades. The Form 4 shows stock option grants to the Chief Legal Officer as compensation, not open-market purchases or sales of existing Vistagen shares on a securities exchange or through a broker.
