Oruka Therapeutics (ORKA) director awarded 9,136 stock options with 2036 expiry

Rhea-AI Filing Summary

Oruka Therapeutics director Carl Dambkowski received a grant of 9,136 stock options on Common Stock. These options have an exercise price of $55.23 per share and expire on June 1, 2036. The grant was a compensation-related award, bringing his directly held stock options to 9,136. According to the vesting terms, the option vests as to 1/12 of the underlying shares monthly beginning on June 2, 2026, so the award becomes exercisable gradually over time rather than immediately.

Insights

Equity compensation analyst

Routine director option grant with time-based monthly vesting.

Director Carl Dambkowski received 9,136 stock options for Oruka Therapeutics, Inc. as a grant or award, with an exercise price of $55.23 and expiration on June 1, 2036. This is a derivative acquisition, not an open-market purchase.

The award vests in equal monthly installments, 1/12 of the underlying 9,136 shares each month starting on June 2, 2026. Such time-based vesting aligns director incentives with longer-term company performance but does not, by itself, signal a change in outlook.

No other derivative positions are listed in this snapshot, and there are no same-day sales or tax-withholding dispositions. As disclosed, this looks like standard equity compensation, with its impact depending mainly on future stock performance and ongoing vesting.

exercise price financial

"conversion_or_exercise_price: "55.2300""

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.

"The option vests as to 1/12 of the underlying shares monthly"

expiration date financial

"expiration_date: "2036-06-01T00:00:00.000Z""

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised.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