Income Taxes
The Company is a corporation and, as a result, is subject to United States federal, state and local income taxes. Solaris LLC is treated as a partnership for United States federal income tax purposes and therefore does not pay United States federal income tax on its taxable income. Instead, the Solaris LLC unitholders, including the Company, are liable for United States federal income tax on their respective shares of Solaris LLC’s taxable income reported on the unitholders’ United States federal income tax returns. Solaris LLC is liable for income taxes in those states not recognizing its status as a partnership for United States federal income tax purposes.
For the three months ended June 30, 2026 and 2025, we recognized a combined United States federal and state expense for income taxes of $5.0 million and $6.0 million, respectively. For the six months ended June 30, 2026 and 2025, we recognized a combined United States federal and state expense for income taxes of $20.2 million and $9.9 million, respectively. The effective combined United States federal and state income tax rates were 16.5% and 19.8% for the three months ended June 30, 2026 and 2025, respectively, and 26.1% and 21.0% for the six months ended June 30, 2026 and 2025, respectively. For the three months ended June 30, 2026, our effective tax rate differed from the statutory rate primarily due to the impact of the non-controlling interest and mix of states where we operate. Our effective tax rate differed from the statutory rate for the six months ended June 30, 2026, primarily due to the impact of the non-controlling interest, the executive compensation deduction limitation and the mix of states where we operate.
The Company’s deferred tax position reflects the net tax effects of the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax reporting. The largest components of the Company’s deferred tax position relate to the Company’s investment in Solaris LLC and net operating loss carryovers. The Company recorded a deferred tax asset and additional paid-in capital for the difference between the book value and the tax basis of the Company’s investment in Solaris LLC. This difference originates from the equity offerings of Class A common stock, exchanges of Solaris LLC units (together with a corresponding number of shares of Class B common stock) for shares of Class A common stock, and issuances of Class A common stock, and corresponding Solaris LLC units, in connection with stock-based compensation.
Based on our cumulative earnings history and forecasted future sources of taxable income, we believe that we will be able to realize our deferred tax assets in the future. As the Company reassesses this position in the future, changes in cumulative earnings history, excluding non-recurring charges, or changes to forecasted taxable income may alter this expectation and may result in an increase to the valuation allowance and an increase in the effective tax rate.
Section 382 of the Internal Revenue Code of 1986, contains rules that limit the ability of a company that undergoes an “ownership change” to utilize its net operating loss and tax credit carryovers and certain built-in losses recognized in years after the “ownership change.” An “ownership change” is generally defined as any change in ownership of more than 50% of a corporation’s stock over a rolling three-year period by stockholders that own (directly or indirectly) 5% or more of the stock of a corporation, or arising from a new issuance of stock by a corporation. If an ownership change occurs, Section 382 generally imposes an annual limitation on the use of pre-ownership change net operating loss carryovers to offset taxable income earned after the ownership change. We do not believe the Section 382 annual limitation related to historical ownership changes impacts our ability to utilize our net operating losses; however, if we were to experience a future ownership change, our ability to use net operating losses may be impacted.
Payables Related to the Tax Receivable Agreement
On May 17, 2017, in connection with its initial public offering (“IPO”), the Company entered into a Tax Receivable Agreement (the “Tax Receivable Agreement”) with the other then-existing members of Solaris LLC. The Tax Receivable Agreement was later amended on June 27, 2023. As of June 30, 2026, our liability under the Tax Receivable Agreement was $109.2 million, representing 85% of the net cash savings in United States federal, state and local income tax or franchise tax that the Company anticipates realizing in future years from certain increases in tax basis and certain tax benefits attributable to imputed interest as a result of the Company’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC units in connection with our IPO or pursuant to previous exercises of the Redemption Right or the Call Right (each as defined in the Solaris LLC Agreement) and additional tax basis arising from any payments the Company makes under the Tax Receivable Agreement.
The projection of future taxable income involves significant judgment. Actual taxable income may differ from our estimates, which could significantly impact our liability under the Tax Receivable Agreement. Therefore, in accordance with ASC 450, Contingencies, we have recorded a liability under the Tax Receivable Agreement related to the tax savings we may realize from certain increases in tax basis and certain tax benefits attributable to imputed interest as a result of the Company’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC units in connection with the IPO or pursuant to previous exercises of the Redemption Right or the Call Right (each as defined in Solaris LLC’s limited liability company agreement) and additional tax basis arising from any payments the Company makes under the Tax Receivable Agreement. Solaris LLC may make cash distributions to the Company in order for the Company to satisfy its obligations under the Tax Receivable Agreement and will be required to distribute cash pro rata to each of the other members of Solaris LLC, in accordance with the number of Solaris LLC units owned by each member at that time.
During the six months ended June 30, 2026, the Company made payments totaling $1.7 million under the Tax Receivable Agreement. Solaris LLC made a cash distribution to the Company of $1.7 million to satisfy these obligations and concurrently made a cash distribution on a pro rata basis to certain Solaris LLC unitholders amounting to $0.4 million.
