Insights

Equity compensation analyst

Routine director option grant with long-dated vesting and standard service condition.

Director Mary Haak‑Frendscho was granted 5,550 Director Stock Options for Surrozen common stock. The exercise price is $30.14 per share, with a final expiration on May 12, 2036. This is classified as a grant or award, not an open‑market purchase or sale.

The footnote states the options vest on the anniversary of the grant date, contingent on continuous board service. Such time‑based vesting is typical for non‑employee directors and aligns incentives with longer‑term company performance without immediate cash outlay by the company.

After this grant, the filing shows 5,550 derivative securities held, with no additional option positions listed. Future company filings may clarify any subsequent equity awards or exercises that change her overall equity exposure.

exercise price financial

"conversion_or_exercise_price": "30.1400""

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.

derivative securities financial

"derivativeTransactionCount": 1"

Financial contracts whose value is tied to the price or performance of another asset, such as a stock, bond, commodity, index, or currency; examples include options, futures and swaps. They matter to investors because they let you protect against price swings, bet on future moves or gain larger exposure with less upfront cash—like using a lever or insurance policy on an investment—so they can amplify gains and losses and help manage portfolio risk.

vesting financial

"The options vest and become exercisable on the anniversary"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
