Rhea-AI Filing Summary

Skye Bioscience Chief Operating Officer Diep Tuan Tu reported a board-approved, one-time repricing of several stock option awards effective March 31, 2026. Existing options with exercise prices between $2.89 and $14.56 per share were surrendered and replaced with new options for the same share amounts at a $0.615 exercise price, matching the closing price on the repricing date.

The grants include, among others, a 150,000-share option expiring on February 25, 2035 and additional options for 75,000, 22,021, 9,194, 8,000 and 7,080 shares at the same $0.615 exercise price. These options generally vest in equal monthly installments over four years from their original vesting start dates and become fully vested upon a change in control. The filing reflects compensation-related option adjustments, not open-market purchases or sales of common stock.

stock option financial
"The exercise price of the stock option is $0.615 per share"
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.
exercise price financial
"The exercise price of the stock option is $0.615 per share"
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.
repricing financial
"approved the one-time repricing of the stock option effective as of March 31, 2026"
vests in equal monthly installments financial
"The stock option vests in equal monthly installments over the four year period"
change in control financial
"Upon a change in control of the Issuer, 100% of the stock option will become fully vested"
A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.
