("New ASP") and Class A common stock and common units ("Opco LLC Interests") of SOLV Energy Holdings LLC ("Opco") are owned directly by ASP Endeavor Investco LP ("ASP Investco") and ASP SOLV Aggregator LP ("ASP SOLV Aggregator"). American Securities Partners VIII(B), L.P. ("Sponsor 1"), ASP VIII Alternative Investments L.P. ("Sponsor 2") and AS/ASP VIII Co-Investor LLC ("Sponsor 3") are the owners of partnership interests in ASP Investco and ASP SOLV Aggregator. American Securities Associates VIII, LLC ("AS Associates VIII") is the general partner of Sponsor 1, Sponsor 2, and New ASP. American Securities LLC ("AS LLC") provides investment advisory services to Sponsor 1, Sponsor 2, and New ASP. ASP VIII SOLV Holdings LP ("Aggregator 1") and ASP VIII CSE Holdings LP ("Aggregator 2") are the owners of the partnership interests in New ASP.
2. AS LLC is also the sole stockholder of ASP Manager Corp. ("ASP Manager"), which is the general partner of ASP Investco, ASP SOLV Aggregator, Aggregator 1 and Aggregator 2 and the manager of Sponsor 3. ASP Investco, ASP SOLV Aggregator, New ASP, Sponsor 1, Sponsor 2, Sponsor 3, AS Associates VIII, Aggregator 1, Aggregator 2, AS LLC and ASP Manager are referred to herein as "Reporting Persons".
3. Pursuant to the limited liability company agreement ("Opco LLCA") of OpCo, each of ASP Investco and ASP SOLV Aggregator is entitled to redeem Opco LLC Interests for, at the Issuer's election, shares of Class A common stock on a one-for-one basis or, using proceeds from a substantially contemporaneous follow-on or secondary offering, a cash payment equal to the price per share of the Class A common stock net of any underwriting discounts or commissions paid in such offering, in each case in accordance with the terms of the Opco LLCA. Upon redemption, an equal number of shares of Class B common stock of the Issuer also held by ASP Investco and/or ASP SOLV Aggregator will be surrendered to and cancelled by the Issuer for no additional consideration. Each share of Class B common stock entitles the holder thereof to one vote per share but carries no economic rights. Opco LLC Interests have no expiration date.
