[Form 4] Corvus Pharmaceuticals, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Corvus Pharmaceuticals director Ian T. Clark received a grant of stock options covering 15,000 shares of common stock. The options have an exercise price of $11.60 per share and expire on June 11, 2036, representing compensation rather than an open-market purchase.

The underlying shares vest and become exercisable in full on the earlier of the first anniversary of the grant date or the company’s 2027 annual stockholder meeting, assuming he continues serving as a director through that date. After this grant, Clark holds stock options for 15,000 shares from this award.

exercise price financial

"conversion_or_exercise_price: 11.6000"

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.

vest and become exercisable financial

"The underlying shares subject to the option vest and become exercisable"

expiration date financial

"expiration_date: 2036-06-11T00:00:00.000Z"

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised.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