Stock Option (right to buy) financial

"security_title: Stock Option (right to buy)"

exercise price financial

"conversion_or_exercise_price: 1.6500"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.

expiration date financial

"expiration_date: 2036-06-15T00:00:00.000Z"

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.

Common Stock financial

"underlying_security_title: Common Stock"

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

FAQ

What did SenesTech (SNES) disclose in this Form 4 for Phillip Nicholas Grandinetti III?

SenesTech reported a stock option grant to director Phillip Nicholas Grandinetti III for 100,000 shares. The options are compensation-related, giving him the right to buy common stock at a fixed exercise price if he chooses to exercise in the future.

How many SenesTech stock options were granted to the director in this filing?

The director received stock options for 100,000 underlying shares of SenesTech common stock. This award increases his derivative holdings, giving him potential future ownership if he exercises the options once they vest and while they remain within their stated term.

What is the exercise price and term of the SenesTech options granted in this Form 4?

The granted stock options have an exercise price of $1.65 per share and expire on June 15, 2036. This creates a long-dated right to purchase SenesTech common shares at that fixed price if the director chooses to exercise.

How do the SenesTech (SNES) director’s new options vest according to the Form 4?

The options vest monthly over one year in 12 equal installments, as noted in the footnote. This means the director’s right to exercise the full 100,000-share award becomes available gradually rather than all at once on the grant date.

Is this SenesTech Form 4 transaction an open-market buy or a compensation grant?

The transaction is a compensation-related grant coded as an acquisition (A), not an open-market purchase. The director pays no price at grant and may later choose to exercise at the fixed $1.65 per-share exercise price if conditions are met.
