2020 Omnibus Incentive Plan - On May 26, 2020, the Board adopted the Omnibus Plan. The Omnibus Plan provides for potential grants of the following awards with respect to shares of the Common Stock and OpCo Units: (i) incentive stock options qualified as such under U.S. federal income tax laws; (ii) non-qualified stock options or any other form of stock options; (iii) stock appreciation rights; (iv) Restricted Stock; (v) Restricted Stock Units; (vi) OpCo Units, and (vii) other equity-based and cash-based incentive awards as determined by the compensation committee of the Board or any properly delegated subcommittee.

The maximum aggregate number of shares of Common Stock that may be issued pursuant to awards under the Omnibus Plan shall not exceed 18,650,000 shares (including OpCo Units or other securities which have been issued under the plan and were converted into awards based on shares of common stock) (the “Plan Share Reserve”). The Omnibus Plan also contains a provision that will add an additional number of shares of Common Stock to the Plan Share Reserve on the first day of each year starting with January 1, 2021, equal to the lesser of (i) the positive difference between (x) 5% of the number of shares of Common Stock outstanding on the last day of the immediately preceding year, and (y) the Plan Share Reserve on the last day of the immediately preceding year, and (ii) a lower number of shares of Common Stock as may be determined by the Board.

The Company currently has equity-based compensation awards outstanding as follows: Restricted Stock Units, Common Stock Options, and Restricted Stock. In addition, the Company recognizes equity-based compensation expense from awards granted to employees as further described below under HSKB Incentive Units.

Except where indicated otherwise, the equity-based compensation awards described below are subject to time-based service requirements. For grants issued prior to June 2020, the service vesting condition is generally over four years with 50% vesting on the two years anniversary of the grant date of the award and the remainder vesting monthly thereafter. For awards made after May 2020 to existing employees, the service vesting condition is generally four years with 25% vesting on the one year anniversary of the grant date of the award and 6.25% vesting quarterly thereafter.

For performance-based Restricted Stock Units (“PRSUs”) issued in the third quarter of 2022, the service vesting condition is one year and specified company performance targets. During the six months ended June 30, 2023, the Company issued PRSUs, which were recommended by the Compensation Committee of the Board and approved by the full Board. The service vesting condition for one of the issued awards is one year. Each of the remaining PRSU awards will vest in annual tranches over a three-year service period. Total PRSUs earned for grants made in 2023 may vary between 0% and 200% of the PRSUs granted based on the attainment of company-specific performance targets during the related performance period and continued service. All of the PRSUs earned will be settled through the issuance of an equivalent number of shares of the Company’s common stock based on the payout level achieved. Certain additional grants have other vesting periods approved by the Compensation Committee of the Board.

All Options outstanding were issued at the time of the IPO in 2020. No additional options have been issued to date. The fair value of Common Stock Options granted at the time of the IPO was determined using the Black-Scholes option pricing model. We estimated the future stock price volatility based on the volatility of a set of publicly traded comparable companies with a look back period consistent with the expected term. The estimated life for the units was based on the expected hold period of private equity owners. The risk-free rate is based on the rate for a U.S. government security with the same estimated life at the time of grant.

On June 3, 2020, the Board adopted the ZoomInfo Technologies Inc. 2020 Employee Stock Purchase Plan (the “ESPP”) that allows eligible employees to purchase shares of the Company's common stock at a discounted price, through payroll deductions of up to 15% of their eligible compensation and the IRS allowable limit per calendar year. The Board’s Compensation Committee administers the ESPP, including with respect to the frequency and duration of offering periods, the maximum number of shares that an eligible employee may purchase during an offering period, and, subject to certain limitations set forth in the ESPP, the per-share purchase price. Currently, the maximum number of shares that can be purchased by an eligible employee under the ESPP is 1,500 shares per offering period and there are two six-month offering periods that begin in the second and fourth quarter of each fiscal year. The purchase price for one share of Common Stock under the ESPP is currently equal to 90% of the fair market value of one share of Common Stock on the first trading day of the offering period or the purchase date, whichever is lower.

The maximum aggregate number of shares of the Common Stock that may be issued under the ESPP is no more than 7,500,000 shares (the “ESPP Plan Share Reserve”). The ESPP plan also contains a provision that will add an additional number of shares of Common Stock to the ESPP Plan Reserve on the first day of each year starting with January 1, 2021, equal to the lesser of (i) the positive difference between (x) 1% of the number of shares of Common Stock outstanding on the last day of the immediately preceding fiscal year, and (y) the ESPP Plan Share Reserve on the last day of the immediately preceding fiscal year, and (ii) a lower number of shares of Common Stock as may be determined by the Board.

The fair value of the ESPP purchase was determined using the Black-Scholes option pricing model. The expected term for the purchases was based on the six-month offering period. We estimate the future stock price volatility based on the historical volatility of the Company with a lookback period commensurate with the expected term of the ESPP purchases. The risk-free rate is the implied yield available on U.S. Treasury zero-coupon bonds issued with a remaining term equal to the expected term.

The Company withheld $1.4 million and $4.4 million worth of ESPP contributions for the three and six months ended June 30, 2023 on behalf of participating employees through payroll deductions included in Accrued expenses and other current liabilities on our Consolidated Balance Sheets. The Company withheld $0.6 million and $0.6 million worth of ESPP contributions for the three and six months ended June 30, 2022 on behalf of participating employees through payroll deductions included in Accrued expenses and other current liabilities on our Consolidated Balance Sheets. The Company purchased 181,931 shares of Common Stock under the ESPP for the three and six months ended June 30, 2023. No shares of Common Stock were purchased under the ESPP for the three and six months ended June 30, 2022. The Company recognized $0.8 million and $2.0 million of equity-based compensation expense related to the ESPP for the three and six months ended June 30, 2023. The Company recognized $0.1 million and $0.1 million of equity-based compensation expense related to the ESPP for the three and six months ended June 30, 2022.

The founders of the Company contributed membership units of ZoomInfo OpCo into an upper tier entity, HSKB Funds, LLC, which is controlled by the current CEO of the Company (“HSKB Manager”). In connection with the Reorganization Transactions, HSKB was reorganized into HSKB I and HSKB II (together, “HSKB”), with HSKB I owning OpCo Units and HSKB II owning HoldCo Units.

During the year ended December 31, 2021, HSKB II exchanged their HoldCo Units and paired shares of Class B common stock of the Company for shares of Class A common stock of the Company pursuant to the terms of the limited liability company agreement of HoldCo. Subsequently, HSKB I exchanged their OpCo Units and paired shares of Class B common stock of the Company for shares of Class A common stock of the Company.

HSKB has issued LLC units to the employees of the Company (“HSKB Grant”) in the form of Class 1 units and Class 2 units. Such units may be exchangeable into one share of Common Stock upon vesting. HSKB awards are recorded as compensation expense of the Company in accordance with the measurement and recognition criteria of ASC 718 for awards made by economic interest holders to employees of the Company.

HSKB has also allocated $31.3 million to be paid in cash over three years from 2019 to 2021 if the holder of an HSKB Grant remains employed by the Company as of the payment date. This pool was further expanded in March 31, 2020, when HSKB allocated an additional $5.3 million to be paid out over three years, starting with March 31, 2020, to holders of HSKB Grants who received grants after the March 2018 Carlyle Investment, subject to the holder’s continued employment by the Company. During the six months ended June 30, 2023, HSKB paid $0.9 million from allocated funds.

In December 2019, HSKB I adopted the HSKB Funds, LLC 2019 Phantom Unit Plan wherein HSKB may grant Phantom Units (“HSKB Phantom Units”) to employees of the Company. HSKB Phantom Units are recorded as compensation expense of the Company in accordance with the measurement and recognition criteria of ASC 718 for awards made by economic interest holders to employees of the Company. HSKB Phantom Units represent the economic equivalent of one share of common stock in the Company. In connection with the Reorganization Transactions, all HSKB Phantom Units were moved from HSKB I to HSKB II. Within 30 days of the later of the date upon which a Phantom Unit vests, HSKB II must settle the HSKB Phantom Unit in exchange for either (1) cash or (2) Common Stock as determined by the HSKB Manager, in each case, equal to the fair market value of such Common Unit at the time of such exchange.
