Rhea-AI Filing Summary

Xencor Inc director Todd E. Simpson received new equity awards as part of his compensation. On June 16, 2026, he was granted 10,302 shares of Common Stock in the form of restricted stock units, which will fully vest on the first anniversary of the grant date.

Following these awards, Simpson directly holds 23,988 shares of Common Stock and 20,604 stock options.

Insights

Equity compensation analyst

Routine director equity grants increase alignment but reflect no open-market buying.

Director Todd E. Simpson received 10,302 restricted stock units and a stock option for 20,604 shares at $12.20 per share. Both awards are characterized as grants or awards, not market purchases, and therefore represent standard equity compensation rather than an investment decision.

The RSUs cliff-vest after one year, while the option vests monthly over a year until June 16, 2027. This structure encourages ongoing service and retention. Because these are non-cash, compensation-related awards with no open-market trades, their informational value for sentiment is limited.

5 terms

restricted stock units financial

"Represents restricted stock units that shall fully vest on the first anniversary of the date of grant."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Stock Option (Right to Buy) financial

"Stock Option (Right to Buy) with 20,604 shares underlying Common Stock."

exercise price financial

"conversion_or_exercise_price: "12.2000" for the stock option grant."

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 in equal monthly installments financial

"The shares subject to the option will vest in equal monthly installments over one year beginning on the one-month anniversary of June 16, 2026."

expiration date financial

"expiration_date: "2036-06-15T00:00:00.000Z" for the stock option."

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.
