9. Convertible Preferred Stock and Stockholders’ Equity

Convertible Preferred Stock

In November 2016, the Company completed a private placement of stock in which investors, including investors affiliated with the directors and officers of the Company, purchased convertible preferred stock and common stock of the Company (the November 2016 Placement). The Company issued 2,819,549 shares of Class A Convertible Preferred Stock, $0.001 par value per share (the Class A Preferred), at $13.30 per share, each of which is convertible into five shares of common stock upon certain conditions defined in the Certificate of Designation of Preferences, Rights and Limitations of the Class A Preferred filed with the Delaware Secretary of State

on November 22, 2016 (the CoD). The Class A Preferred were purchased exclusively by entities affiliated with Redmile Group, LLC (collectively, Redmile). The terms of the CoD prohibited Redmile from converting the Class A Preferred into shares of the Company’s common stock if, as a result of conversion, Redmile, together with its affiliates, would own more than 9.99% of the Company’s common stock then issued and outstanding (the Redmile Percentage Limitation), which percentage could change at Redmile’s election upon 61 days’ notice to the Company to (i) any other number less than or equal to 19.99% or (ii) subject to approval of the Company’s stockholders to the extent required in accordance with the NASDAQ Global Market rules, any number in excess of 19.99%. On May 2, 2017, the Company’s stockholders approved the issuance of up to an aggregate of 14,097,745 shares of common stock upon the conversion of the outstanding shares of Class A Preferred. As a result, Redmile has the right to increase the Redmile Percentage Limitation to any percentage in excess of 19.99% at its election. The Company also issued 7,236,837 shares of common stock at $2.66 per share as part of the November 2016 Placement. In April 2023, the Company filed with the office of the Secretary of State of the State of Delaware a Certificate of Amendment to Certificate of Designation of Preferences, Rights and Limitations of Class A Convertible Preferred Stock which amends the definition of Beneficial Ownership Limitation to be 14.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the issuance of shares of common stock pursuant to a Notice of Conversion. In April 2023, 33,441 shares of Class A Preferred were converted into 167,205 shares of the Company’s common stock. In December 2024, 6,022 shares of the Class A Preferred were converted into 30,110 shares of the Company’s common stock.

The Class A Preferred are non-voting shares and are convertible into five shares of the Company’s common stock at a conversion price of $2.66 per share, which was the fair value of the Company’s common stock on the date of issuance. Holders of the Class A Preferred have the same dividend rights as holders of the Company’s common stock. Additionally, the liquidation preferences of the Class A Preferred are pari passu among holders of the Company’s common stock and holders of the Class A Preferred, pro rata based on the number of shares held by each such holder (treated for this purpose as if the Class A Preferred had been converted to common stock).

Stock Option and Incentive Plans and Inducement Equity Plan

2022 Stock Option and Incentive Plan

On June 9, 2022, the Company adopted the 2022 Stock Option and Incentive Plan (the 2022 Plan). The 2022 Plan initially authorized 9.5 million shares, and in June 2024, stockholders approved an additional 8,000,000 shares, of common stock for issuance and allows for the grant of stock options, stock appreciation rights, restricted stock awards, performance-based awards, and other awards to individuals who are then employees, officers, directors or consultants of the Company. The shares of common stock underlying any awards from the 2022 Plan and a previously existing equity plan from 2013 or 2007 that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without any issuance of common stock, expire or are otherwise terminated (other than by exercise) are added back to the shares of common stock available for issuance under the 2022 Plan.

Recipients of stock options under the 2022 Plan shall be eligible to purchase shares of the Company’s common stock at an exercise price equal to no less than the estimated fair value of such stock on the date of grant. Under the 2022 Plan, stock options generally vest 25% on the first anniversary of the original vesting date, with the balance vesting monthly over the remaining three years, or vest monthly over four years, unless they contain specific performance and/or market-based vesting provisions. The maximum term of stock options granted under the 2022 Plan is ten years. Under the 2022 Plan, restricted stock units generally vest annually over four years. Performance-based stock units/awards vest upon the achievement of certain pre-defined company-specific performance-based clinical achievement criteria.

Inducement Plan

On May 10, 2016, the Company’s board of directors approved the Fate Therapeutics, Inc. Inducement Equity Plan (the Inducement Plan), the purpose of which is to enable the Company to grant equity awards to induce highly-qualified prospective officers and employees who are not employed by the Company to accept employment with the Company. Under the Inducement Plan, the Company may grant non-qualified stock options and restricted stock units. A total of 500,000 shares of common stock were initially reserved for issuance under the Inducement Plan. In January 2021, March 2020, and January 2019, an additional 300,000 shares, 470,822 shares, and 200,000 shares, respectively, of common stock were reserved for issuance under the Inducement Plan. The shares of common stock underlying any awards from the Inducement Plan that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without any issuance of common stock, expire or are otherwise terminated (other than by exercise) under the Inducement Plan will be added back to the shares of common stock available for issuance under the Inducement Plan.

Pre-Funded Warrants

In January 2021, in conjunction with a public offering, the Company issued Pre-Funded Warrants, in lieu of common stock to certain investors, to purchase 257,310 shares of the Company’s common stock (the 2021 Pre-Funded Warrants). The purchase price for the 2021 Pre-Funded Warrants was $85.499 per pre-funded warrant, which equals the per share public offering price for the shares of common stock less the $0.001 exercise price for each such pre-funded warrant. Given that the 2021 Pre-Funded Warrants are indexed to the Company’s own shares of common stock (and otherwise meet the requirements to be classified in equity), the Company recorded the consideration received from the issuance of the warrants as additional paid-in capital on the Company’s consolidated balance sheets.

In March 2024, in conjunction with a public offering, the Company issued in a private placement, in lieu of common stock to certain investors, pre-funded warrants to purchase 3,636,364 shares of the Company’s common stock (2024 Pre-Funded Warrants, and collectively with the 2021 Pre-Funded Warrants, the Pre-Funded Warrants). The purchase price for the 2024 Pre-Funded Warrants was $5.499 per pre-funded warrant, which equals the per share public offering price for the shares of common stock issued in the March 2024 public offering, less the $0.001 exercise price for each such pre-funded warrant. Given that the 2024 Pre-Funded Warrants are indexed to the Company’s own shares of common stock (and otherwise meet the requirements to be classified in equity), the Company recorded the consideration received from the issuance of the warrants as additional paid-in capital on the Company’s unaudited condensed consolidated balance sheets.

The Pre-Funded Warrants are exercisable at any time after the date of issuance. A holder of Pre-Funded Warrants may not exercise the Pre-Funded Warrant if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to such exercise. A holder of Pre-Funded Warrants may increase or decrease this percentage not in excess of 19.99% by providing at least 61 days’ prior notice to the Company.

As of December 31, 2024, there were 3,893,674 Pre-Funded Warrants outstanding.

Stock Options and Restricted Stock Unit Awards

Stock Options. The following table summarizes stock option activity and related information under all equity plans for the year ended December 31, 2024:

For the years ended December 31, 2024 and 2023, the weighted average grant date fair value of stock options granted per share was equal to $4.89 and $4.83, respectively.

As of December 31, 2024 and 2023, the unrecognized compensation cost related to outstanding options was $15.4 million and $23.0 million, respectively, which was expected to be recognized as expense over approximately 1.6 years and 1.9 years, respectively.

The total intrinsic value, which is the amount by which the exercise price was exceeded by the price of the Company’s common stock on the date of exercise, of stock options exercised during the year ended December 31, 2023 was $0.3 million. As of December 31, 2024, all outstanding options had an exercise price above the Company's common stock price and therefore no intrinsic value. Total cash received upon the exercise of stock options was $0.1 million for the year ended December 31, 2024.

Restricted Stock Units. The following table summarizes restricted stock unit activity and related information under all equity plans for the year ended December 31, 2024:

During the year ended December 31, 2024, the Company granted 300,000 performance-based restricted stock units with a total grant date fair value of approximately $1.6 million, none of which have vested. There were 1,062,607 and 1,020,617 PRSUs outstanding at December 31, 2024 and 2023, respectively.

Stock-Based Compensation Expense

Stock Option Grants Valuation. The weighted-average assumptions used in the Black-Scholes option pricing model to determine the fair value of the employee and nonemployee stock option grants were as follows:

Risk-free interest rate. The Company bases the risk-free interest rate assumption on observed interest rates appropriate for the expected term of the stock option grants.

Expected dividend yield. The Company bases the expected dividend yield assumption on the fact that it has never paid cash dividends and has no present intention to pay cash dividends.

Expected volatility. The Company based the expected volatility on the historical volatility of its common stock over the most recent period commensurate with the estimated expected term of the Company’s stock options, as the Company determined there was sufficient operating history and company-specific historical volatility to estimate the expected volatility.

Expected term. The expected term represents the period of time that options are expected to be outstanding. The Company estimated the expected term using historical experience and anticipated future exercise behavior.
