did not otherwise receive any annual bonuses for Equity Compensation Prior to this offering, our equity incentive program generally consisted of grants of “Compensatory Units” in ER Holdings. The Compensatory Units are intended to qualify as “profits interests” for U.S. income tax purposes. The Compensatory Units are designed to align the NEOs’ interests with the interests of our equity holders and represent interests in the profits of ER Holdings in excess of a certain “Threshold Amount” that acts similarly to a strike price for a stock option in that the holder will only realize value in excess of such amount. The Threshold Amount has traditionally been reviewed and set in conjunction with a third-party valuation. Certain of our NEOs also historically received grants of profits interest units in ERock Holdings, Ltd. (an affiliated entity of ER Holdings) in 2015 and 2016, all of which were fully vested prior to 2025.

Compensatory Units have been granted to new executives upon hire, or a short time
thereafter, and grant amounts have been determined after considering internal pay and equity alignment and external factors, including but not limited to the value of any forfeited compensation opportunities from a prior employer. Compensatory Units
are also granted from time-to-time for purposes related to recognition, promotion, retention, increased role or responsibilities and other factors. In connection with
their respective appointment and/or recognition of their performance, during 2025, each of Messrs. Amthor, Blakely, and Froutan received a grant of Compensatory Units. Mr. Carrington received a grant of Compensatory Units in connection with his
service on the Board and an additional grant upon his appointment as Chief Executive Officer. During 2025, the Threshold Amount of certain prior Compensatory Unit grants were adjusted in order to preserve the incentive and retention value of such
awards, including certain units held by Messrs. Amthor, Blakely, and Froutan, as further described in the footnotes to the Summary Compensation Table above.

Employment Agreements

John Carrington

In connection with his appointment as Chief Executive Officer, Enchanted Rock Management, LLC (“ER Management”), a
subsidiary of ER Holdings, entered into an employment agreement with Mr. Carrington pursuant to which he is eligible to receive (i) an annual base salary of $500,000, (ii) an annual bonus with a target equal to 100% of his base salary, and
(iii) a one-time bonus equal to $100,000 upon the Debt Repayment (which was paid in December of 2025 and was intended to be in lieu of the cash bonus upon Debt Repayment in his director letter agreement
described below). Such agreement has an initial term of one year and will automatically renew for additional one-year terms unless a non-renewal notice is provided no
later than 30 days prior to the expiration of the then-current term. Upon a termination of his employment by ER Management without Cause (including non-renewal of the agreement) or by him for Good Reason,
subject to his execution of a release of claims, he will be entitled to receive: (i) cash severance payments equal to 12 months of his base salary, payable in monthly installments over 12 months, (ii) a
pro-rated annual bonus for the year of termination based on actual performance of any performance metrics, (iii) any earned annual bonus for the year prior to the year of termination, and
(iv) payment of his full premiums for continuation of group health benefits under COBRA for up to 12 months.

“Cause” for purposes of Mr. Carrington’s employment agreement generally means: (i) his material
breach of the employment agreement, ER Holdings’ limited liability company agreement or any other written agreements with ER Holdings and its affiliates, (ii) his material breach of any written policy or code of conduct, (iii) his
gross negligence or willful misconduct in connection with the performance of his duties, or violation of any law applicable to the workplace, (iv) his breach of fiduciary duty, fraud, theft or embezzlement, (v) his commission, or
conviction or indictment of, or plea of nolo contendere to, any felony or any crime involving

moral turpitude, or (vi) his willful failure or refusal, other than due to disability, to perform his obligations or to follow any lawful directive from the Board. If his actions or
omissions as set forth in clauses (i), (ii), (iii) or (vi) are curable, then he will receive a 30-day cure period.

“Good Reason” for purposes of Mr. Carrington’s employment agreement generally means: (i) a
material breach by ER Management of the employment agreement, (ii) a material diminution in his duties, title, authority or responsibilities, or (iii) a material reduction in his base salary (other than any
across-the-company reductions affecting substantially all of the senior executives and which reduction does not reduce his base salary by more than 10%). He must provide
ER Management a 30-day cure period following written notice of the condition constituting Good Reason.

Prior to his appointment as Chief Executive Officer, ER Holdings and Mr. Carrington were parties to a letter agreement
with respect to his services as a director, pursuant to which he was eligible to receive (i) a biweekly fee of $8,333, (ii) a $475,000 additional cash payment upon the Debt Repayment, which was subsequently reduced to $100,000 pursuant to his
employment agreement as described above, and (iii) 2,323 Compensatory Units, of which 50% vested upon the Debt Repayment and the remaining 50% vests in 12 equal monthly installments commencing on January 9, 2026. Upon his appointment as Chief
Executive Officer, Mr. Carrington also received a grant of 22,715 Compensatory Units, which vests in equal monthly installments over thirty-six months commencing on December 26, 2025, subject to his
continued service with the Company through the applicable vesting dates.

partner. Such agreement provided for Mr. Amthor’s base salary and eligibility to receive a discretionary bonus determined at the sole discretion of ER Management based on individual and overall organization performance.

Ian Blakely

Management entered into an offer letter and employment agreement with Mr. Blakely in January 2015, which provide for his base salary, eligibility to receive a discretionary bonus determined at the sole discretion of ER Management based on
individual and overall organization performance, and eligibility to receive a grant of profits interest units (which were granted as profits interest units in ERock Holdings, Ltd.).

Paul Froutan

Management entered into an offer letter and employment agreement with Mr. Froutan in May 2022, which provide for his base salary, eligibility to receive a discretionary bonus determined at the sole discretion of ER Management based on
individual and overall organization performance, and a grant of Compensatory Units which vests 25% one year after the date of grant and the remaining 75% in equal monthly installments thereafter.

Thomas McAndrew

Management entered into an employment agreement with Mr. McAndrew in June 2025 in connection with his transition to the role of advisor to the Chief Executive Officer, which has an initial term of one year and may be extended by mutual
agreement. Such agreement provides for (i) an initial annual base salary of $200,000 that increased to $275,000 upon the Debt Repayment, (ii) a cash incentive equal to $75,000 multiplied by the product of (a) 1.5 and (b) a fraction
the numerator of which is the number of months that elapsed between the date of the agreement and the Debt Repayment date and the denominator of which is 12 (the “Debt Repayment Success Fee”), and (iii) eligibility to receive
commissions on sales agreements entered into with certain parties, which commissions are reduced by his company-reimbursed expenses, his base salary, the earned Debt

time, without Cause upon 90 days advance written notice, or upon written notice in the event of disability or upon death. If Mr. McAndrew’s employment is terminated without Cause prior to the end of the initial term, he will receive any
earned sales commissions through the end of the 90-day notice period. The agreement also contains non-competition covenants covering the
one-year period post-termination or until his termination date if he is terminated without Cause prior to the end of the initial term, in which case ER Management may elect to extend the non-compete period for one year subject to ER Management’s payment of his base salary through such extension period. ER Management also agreed to pay 100% of the premiums for Mr. McAndrew’s coverage
under ER Management’s health and other insurance plans.
