FAQ

What did Enanta (ENTA) director Yujiro S. Hata report on this Form 4?

Yujiro S. Hata reported receiving a grant of stock options for 20,000 shares of Enanta common stock. These options are a compensation-related award, not an open-market share purchase or sale, and give him the right to buy shares at a fixed exercise price.

How many Enanta (ENTA) stock options were granted and at what exercise price?

The filing shows a grant of stock options covering 20,000 shares of Enanta common stock at a $14.17 exercise price. This means Hata can later purchase those shares at $14.17 per share if he exercises the options after they vest.

When do Yujiro S. Hata’s Enanta (ENTA) stock options vest?

The options vest monthly in substantially equal installments over one year starting from the March 11, 2026 grant date. The final monthly installment will vest no later than the nearest Nasdaq Global Select Market trading day before Enanta’s 2027 annual meeting of stockholders.

When do the Enanta (ENTA) stock options granted to Hata expire?

The stock options granted to Yujiro S. Hata expire on March 11, 2036. After that expiration date, any unexercised portion of the 20,000-share option grant can no longer be used to purchase Enanta common stock at the $14.17 exercise price.

Is this Enanta (ENTA) Form 4 a market transaction or a compensation grant?

This Form 4 reflects a compensation grant, not an open-market trade. The transaction code “A” denotes a grant or award acquisition of stock options, giving Hata the right to buy 20,000 Enanta shares at $14.17, subject to the stated vesting schedule and expiration date.

What is Yujiro S. Hata’s position in Enanta (ENTA) options after this grant?

After the reported grant, Hata directly holds stock options covering 20,000 shares of Enanta common stock. The filing does not list additional derivative positions, so this 20,000-share option award represents his reported derivative holding following the March 11, 2026 compensation grant.
