Non-Qualified Stock Options financial
"Includes 17,731 non-qualified stock options ("Stock Options") exercisable solely into common stock"
Non-qualified stock options are a type of employee benefit that gives individuals the right to buy company shares at a set price, usually lower than the market value, within a certain period. Unlike other options that may have special tax advantages, these options are taxed as income when exercised, which can affect how much money the employee or investor ultimately gains. They are important because they can influence company compensation strategies and impact the financial outcomes for employees and investors.
2018 Equity Incentive Plan financial
"granted by the Issuer to Felix J. Baker ... pursuant to the Issuer's 2018 Equity Incentive Plan"
indirect pecuniary interest financial
"each may be deemed to have an indirect pecuniary interest in the Stock Options"
voting and dispositive power financial
"the Adviser has voting and dispositive power over the Stock Options and any Common Stock"
beneficial ownership financial
"disclaim beneficial ownership of the securities held for the benefit of the Funds"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
Section 16 regulatory
"beneficial owner of such securities for purposes of Section 16 or any other purpose"
Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.

FAQ

What insider transaction did Kodiak Sciences (KOD) report in this Form 4?

Kodiak Sciences reported a grant of 17,731 non-qualified stock options to director Felix J. Baker. These options are tied to Baker-affiliated funds and provide the right to buy Kodiak common stock at a set price under the 2018 Equity Incentive Plan.

How many Kodiak Sciences stock options were granted and at what strike price?

The filing shows a grant of 17,731 non-qualified stock options with a strike price of $38.96 per share. Each option is exercisable solely into Kodiak Sciences common stock, giving exposure at that fixed exercise price if conditions are met.

When do the newly granted Kodiak Sciences options vest and expire?

The options vest on the earlier of the first anniversary of the June 30, 2026 grant date or one day before Kodiak Sciences’ next annual stockholder meeting. They expire on June 29, 2036, providing a long-dated potential exercise window if vested.

Who has voting and investment power over the Kodiak Sciences options reported?

Baker Bros. Advisors LP has complete discretion over investment and voting power for securities held for the benefit of the Baker funds. The general partners relinquished this authority, so the adviser controls voting and dispositive power over these options and any resulting common stock.

Do Julian and Felix Baker directly own the Kodiak Sciences options in this filing?

Julian and Felix Baker may be deemed to have an indirect pecuniary interest through their ownership interests in the Baker funds and related entities. However, they and the adviser disclaim beneficial ownership beyond their economic interest and do not have direct pecuniary rights to the compensation securities.

Why is the same Kodiak Sciences option grant reported for multiple Baker entities?

The Form 4 explains that the 17,731-stock-option grant to Felix J. Baker is reported for each Baker fund because each fund has an indirect proportionate pecuniary interest. This structure spreads economic exposure across 667, L.P., Baker Brothers Life Sciences LP and related partnerships.
