exercise price financial
"conversion_or_exercise_price: 36.0500"
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: 2036-06-29T00:00:00.000Z"
The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised.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.

FAQ

What insider transaction did CALIX (CALX) report for Carl Russo?

CALIX reported that director and ten percent owner Carl Russo received a grant of 15,999 stock options. These options give him the right to buy common shares at a fixed exercise price as part of his equity-based compensation arrangement.

The grant covers 15,999 stock options with an exercise price of $36.0500 per share, expiring June 29, 2036. These options are a compensation award rather than an open-market purchase of CALIX common stock.

How do Carl Russo’s CALIX (CALX) stock options vest over time?

The options vest in four equal installments, with 25% of the underlying shares vesting on each anniversary of the June 29, 2026 grant date. This structure encourages longer-term alignment between Russo’s incentives and CALIX’s multi-year performance.

What does the $36.0500 exercise price mean for CALIX (CALX) options granted to Russo?

The $36.0500 exercise price is the cost per share Russo must pay to convert each option into CALIX common stock once vested. The economic value of the award depends on CALIX’s future share price relative to this fixed strike level.
