ASC 718 requires compensation expense associated with share-based awards to be recognized over the requisite service period which, for the Company, is the period between the grant date and the date the award vests or becomes exercisable. The Company recognizes all share-based awards under the straight-line attribution method, assuming that all granted awards will vest. Forfeitures are recognized in the periods when they occur.

Stock based compensation has been reported within expense line items on the consolidated statement of operations for the three and six months ended June 30, 2024 and 2023 as shown in the following table (in $000s):


	Three Months Ended				Six Months Ended

In May 2018, the Company’s stockholders approved the 2018 Equity Incentive Plan (the “2018 Plan”), under which Cyclacel may make equity incentive grants to its officers, employees, directors and consultants. The 2018 Plan replaced the 2015 Equity Incentive Plan (the “2015 Plan”).

The 2018 Plan allows for various types of award grants, including stock options and restricted stock units.

On June 21, 2024, the Company’s stockholders approved an additional 160,000 shares of common stock that may be issued under the 2018 Plan. On June 13, 2023, the Company’s stockholders approved an additional 60,000 shares of common stock that may be issued under the 2018 Plan. As of June 30, 2024, the Company has reserved 190,039 shares of the Company’s common stock under the 2018 Plan for future issuances. Stock option awards granted under the Company’s equity incentive plans have a maximum life of 10 years and generally vest over a one to four-year period from the date of grant.

In October 2020, the Inducement Equity Incentive Plan (the “Inducement Plan”), became effective. Under the Inducement Plan, Cyclacel may make equity incentive grants to new senior level Employees (persons to whom the Company may issue securities without stockholder approval). The Inducement Plan allows for the issuance of up to 13,333 shares of the Company’s common stock (or the equivalent of such number). As of June 30, 2024, 8,000 shares under the Inducement Plan have been issued, leaving a remaining reserve of 5,333 shares.

There were 12,500 options granted during the six months ended June 30, 2024, all issued under the 2018 Plan. These options had a grant date fair value of $1.77 per option. There were 43,342 options granted during the six months ended June 30, 2023. These options had a grant date fair value ranging between $6.32-$10.98 per option.

All of the options granted during the six months ended June 30, 2024 shall vest six months from their date of grant. Of the options granted during the six months ended June 30, 2023, 25,633 awards shall vest on the third anniversary of their date of grant, or earlier if either of the certain performance conditions are met relating to enrollment goals for various clinical studies. The Company has assumed that these awards will vest after three years as satisfaction of the performance conditions is not probable at this time.

The fair value of the stock options granted is calculated using the Black-Scholes option-pricing model as prescribed by ASC 718 using the following assumptions:



	Six months ended	Six months ended
	June 30, 2024	June 30, 2023
Expected term (years)	6	5 - 6
Risk free interest rate	3.995%	3.660% – 4.050%
Volatility	93%	89% – 92%
Expected dividend yield over expected term	0.00%	0.00%
Resulting weighted average grant date fair value	$1.77	$6.63

There were no stock options exercised during each of the six months ended June 30, 2024 and 2023, respectively. The Company does not expect to be able to benefit from the deduction for stock option exercises that may occur because the company has tax loss carryforwards from prior periods that would be expected to offset any potential taxable income.

As of June 30, 2024, the total remaining unrecognized compensation cost related to the non-vested awards with service conditions amounted to approximately $0.4 million, which will be amortized over the weighted-average remaining requisite service period of 1.46 years.

The Company issued 12,500 restricted stock units during the six months ended June 30, 2024. These restricted stock units vest monthly over a six-month service period. These restricted stock units were valued at $2.28 at the date of grant, which was equivalent to the market price of a share of the Company’s common stock on that date.

A total of 17,133 restricted stock units issued in January 2023 vest on the third anniversary of their date of grant, or earlier if certain defined clinical trial related performance targets are met. A three-year vesting assumption was applied to these restricted stock units as satisfaction of the performance conditions is not probable at this time. Each of these restricted stock units was valued at $13.50 at the date of grant, which was equivalent to the market price of a share of the Company’s common stock on that date. During 2023, 300 of these restricted stock units were forfeited as the recipient voluntarily terminated employment with the Company. Through June 30, 2024, an additional 6,072 of these restricted stock units have been forfeited due to the holders’ termination of employment with the Company.

Summarized information for restricted stock units as of June 30, 2024 is as follows:
