SHARE-BASED COMPENSATION
The Cipher Mining Inc. 2021 Incentive Award Plan (the “Incentive Award Plan”) provides for the grant of stock options, including incentive stock options and nonqualified stock options, stock appreciation rights, RSUs and other stock or cash-based awards to employees, consultants and directors. Upon vesting of an award, the Company may either issue new shares or reissue treasury shares.
Initially, up to 19,869,312 shares of Common Stock were available for issuance under awards granted pursuant to the Incentive Award Plan. In addition, the number of shares of Common Stock available for issuance under the Incentive Award Plan is increased on January 1 of each calendar year beginning in 2022 and ending in 2031 by an amount equal to the lesser of (a) three percent (3%) of the total number of shares of Common Stock outstanding on the final day of the immediately preceding calendar year and (b) such smaller number of shares determined by the Board. On January 1, 2025, this resulted in an increase of 10,523,515 shares of Common Stock available for issuance under the Incentive Award Plan. As of December 31, 2025, 15,118,752 shares of Common Stock were available for issuance under the Incentive Award Plan.

Service-based RSUs
A summary of the Company's unvested Service-Based RSU activity for the year ended December 31, 2025 is shown below:
| | | | | | | | | | | |
| Number of Shares | | Weighted Average Grant Date Fair Value |
| Unvested at December 31, 2024 | 15,922,220 | | $ | 2.65 | |
| Granted | 4,805,472 | | $ | 5.83 | |
Vested | (10,084,960) | | $ | 2.79 | |
| Unvested at December 31, 2025 | 10,642,732 | | $ | 3.95 | |
As of December 31, 2025, there was approximately $25.5 million of unrecognized compensation expense related to unvested Service-Based RSUs, which is expected to be recognized over a weighted-average vesting period of approximately 0.9 years.
If not fully vested upon grant, service-based RSUs awarded generally vest over a period ranging from three to four years in installments as determined by the Board.
Vesting is subject to the award recipient’s continuous service on the applicable vesting date; provided, that if the award recipient’s employment is terminated by the Company without “cause”, by award recipient for “good reason” (if applicable, as such term or similar term may be defined in any employment, consulting or similar service agreement between award recipient and the Company) or due to award recipient’s death or permanent disability, all unvested service-based RSUs will vest in full (unless otherwise specified in the agreement between the award recipient and the Company). In addition, in the event of a change in control, any unvested service-based RSUs will vest subject to the award recipient’s continuous service to the Company through such change in control. In addition, if the Company achieves a $10 billion market capitalization milestone (described further below) and the CEO remains in continuous service through such achievement, any then-unvested service-based RSUs awarded to the CEO will also vest.
Performance-Based RSUs
In 2021, the Company issued 4,257,710 performance-based RSUs (the “2021 Performance-Based RSUs”) at a weighted average grant date fair value of $7.76. As of December 31, 2025, 2,838,474 of the 2021 Performance-Based RSUs were vested.
There was no unrecognized compensation expense related to unvested performance-based RSUs at December 31, 2025.
Two-thirds of the outstanding 2021 Performance-Based RSUs have vested upon the Company achieving a market capitalization equal to or exceeding $5 billion and $7.5 billion. One-third remains outstanding and will vest upon the company achieving a market capitalization equal to or exceeding $10 billion, over a 30-day lookback period and subject to the CEO’s continuous service through the end of the applicable 30-day period. In the event of a change in control and CEO’s continuous service through such change in control, the per share price (plus the per share value of any other consideration) received by the Company’s stockholders in such change in control will be used to determine whether any of the market capitalization milestones are achieved (without regard to the 30-day lookback period). Any 2021 Performance-Based RSUs that do not vest prior to the CEO’s termination of service or, if earlier, in connection with a change in control will be forfeited for no consideration.
On February 26, 2025, the Company issued an additional 2,490,943 Performance-Based RSUs (the “2025 Performance-Based RSUs”) to the Company’s senior management team under the Incentive Award Plan at a weighted average grant date fair value of $5.01. There was approximately $7.5 million in unrecognized compensation expense related to the 2025 Performance-Based RSUs at December 31, 2025, which is expected to be recognized over a weighted-average vesting period of approximately 1.13 years, regardless of whether the market conditions required for vesting are achieved.
As of the end of the performance period, the Compensation Committee of the Board of Directors certified that the Company’s common stock achieved the necessary Total Shareholder Return (TSR) relative to the TSR of peer companies identified in the grant agreements and overall TSR for the performance period, and earned 225% of the 2025 Performance-Based RSUs originally granted, resulting in the issuance of 5,604,621 shares. One-third of the earned PSUs vested on December 31, 2025, and the remaining two-thirds of the earned PSUs will vest in equal quarterly installments over the following two years with the first such vesting date occurring on March 31, 2026.
The grant date fair value of the 2025 Performance-Based RSUs was measured using a Monte Carlo simulation model based on the following assumptions:

| Risk-free interest rate | 4.14% |
