Tyra Biosciences (NASDAQ: TYRA) grants 13,160 stock options to director Adele Gulfo

Rhea-AI Filing Summary

Tyra Biosciences director Adele M. Gulfo received a stock option grant for 13,160 shares of common stock at an exercise price of $32.68 per share. This award was issued under the company’s Non-Employee Director Compensation Program and represents compensation rather than an open-market purchase.

The option vests over time: one-twelfth of the shares vest monthly after the May 28, 2026 grant date. If the next annual shareholder meeting occurs before the first anniversary of the grant, any remaining unvested portion will vest on that meeting date, provided she continues serving the company through each vesting date.

Non-Employee Director Compensation Program financial

"The option was granted pursuant to the Issuer's Non-Employee Director Compensation Program."

stock option financial

"The option was granted pursuant to the Issuer's Non-Employee Director Compensation Program."

A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.

vest financial

"1/12th of the total number of shares of common stock subject to the option vest monthly following May 28, 2026, the date of grant."

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

expiration date financial

"expiration_date": "2036-05-27T00:00:00.000Z""

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised.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.
