Summit Inc.’s tax provision includes its proportional share of Summit Holdings’ tax attributes. Summit Holdings’ subsidiaries are primarily limited liability companies but do include certain entities organized as C corporations and a Canadian subsidiary. The tax attributes related to the limited liability companies are passed on to Summit Holdings and then to its partners, including Summit Inc. The tax attributes associated with the C corporation and Canadian subsidiaries are fully reflected in the Company’s accounts.

Our income tax expense was $20.5 million and $33.5 million in the three and nine months ended October 2, 2021, respectively, and our income tax benefit was $(19.6) million and $(25.3) million in the three and nine months ended September 26, 2020, respectively. The effective tax rate for Summit Inc. differs from the federal statutory tax rate

primarily due to (1) unrecognized tax benefits in 2020, (2) state taxes, (3) tax depletion expense in excess of the expense recorded under U.S. GAAP, (4) the minority interest in the Summit Holdings partnership that is allocated outside of the Company and (5) various other items such as limitations on meals and entertainment, certain stock compensation and other costs. In the first quarter of 2020, we recorded the impact of the Coronavirus Aid, Relief and Economic Stability Act ("CARES Act") enacted into law in late March 2020, which reduced our unrecognized tax benefits by approximately $9.5 million. In the third quarter of 2020, final regulations were issued clarifying portions of the Tax Cuts and Jobs Act of 2017 ("TCJA"). Under the provisions of the final regulations, we reversed unrecognized tax benefits of $32.9 million in the third quarter of 2020.

As of October 2, 2021 and January 2, 2021, Summit Inc. had a valuation allowance of $1.7 million, which relates to certain deferred tax assets in taxable entities where realization is not more likely than not.

No material interest or penalties were recognized in income tax expense during the three and nine months ended October 2, 2021 and September 26, 2020.

Tax Receivable Agreement—The Company is party to a TRA with certain current and former holders of LP Units that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. actually realizes (or, under certain circumstances such as an early termination of the TRA, is deemed to realize) as a result of increases in the tax basis of tangible and intangible assets of Summit Holdings and certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments under the TRA. 

In the nine months ended October 2, 2021, 1,440,983 LP Units were acquired by Summit Inc. in exchange for an equal number of newly-issued shares of Summit Inc.’s Class A common stock. These exchanges resulted in net new deferred tax assets of approximately $10.8 million. As we determined that the deferred tax assets created from these exchanges are realizable and payment under the TRA is considered probable, we have recorded 85% of the increase in deferred tax assets as TRA liability and the remainder as an adjustment to additional paid in capital. As of October 2, 2021 and January 2, 2021, we had recorded $330.9 million and $321.7 million of TRA liability, respectively.

Tax Distributions – The holders of Summit Holdings’ LP Units, including Summit Inc., incur U.S. federal, state and local income taxes on their share of any taxable income of Summit Holdings. The limited partnership agreement of Summit Holdings provides for pro rata cash distributions (“tax distributions”) to the holders of the LP Units in an amount generally calculated to provide each holder of LP Units with sufficient cash to cover its tax liability in respect of the LP Units. In general, these tax distributions are computed based on Summit Holdings’ estimated taxable income allocated to Summit Inc. multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate in New York, New York. Summit Holdings did not make any tax distributions in the nine months ended October 2, 2021 and September 26, 2020.

Summit LLC is a limited liability company and passes its tax attributes for federal and state tax purposes to its parent company and is generally not subject to federal or state income tax. However, certain subsidiary entities file federal, state and Canadian income tax returns due to their status as taxable entities in the respective jurisdiction. The effective income tax rate for the C Corporations differs from the statutory federal rate primarily due to (1) tax depletion expense in excess of the expense recorded under U.S. GAAP, (2) state income taxes and the effect of graduated tax rates and (3) various other items, such as limitations on meals and entertainment and other costs. The effective income tax rate for the Canadian subsidiary is not significantly different from its historical effective tax rate.

No material interest or penalties were recognized in income tax expense during the three and nine months ended October 2, 2021 and September 26, 2020. We recognized uncertain tax benefits in the three and nine months ended March 28, 2020 related to the passage of the Coronavirus Aid, Relief and Economic Stability Act (“CARES Act”) on March 25, 2020.
