Management assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. On the basis of this evaluation, for the fiscal year ended March 31, 2026, no material change to the valuation allowance account of $1.3 million has been recorded to recognize only the portion of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased.
As of March 31, 2026, the Company has provided for earnings in foreign subsidiaries that are not considered to be indefinitely reinvested and therefore subject to withholding taxes on $124.3 million of undistributed foreign earnings, recording a deferred tax liability of approximately $8.9 million thereon.

Nextpower and its subsidiaries file federal, state, and local income tax returns in multiple jurisdictions around the world. With few exceptions, Nextpower is no longer subject to income tax examinations by tax authorities for years before 2018.
The Company recognizes interest and penalties accrued related to unrecognized tax benefits within the Company’s tax expense. The Company had immaterial accrued interest and penalties as of March 31, 2026 and 2025, respectively. To the extent taxes are not assessed with respect to uncertain tax positions, substantially all amounts accrued (including interest and penalties) will be reduced and reflected as a reduction of the overall income tax provision.
The Company has entered into 45X Credit transfer and assignment agreements with certain suppliers which resulted in an offset of the Company’s federal tax payable by $130.1 million and $63.8 million for the fiscal years ended March 31, 2026 and 2025, respectively.
Tax Receivable Agreement
On February 13, 2023, Nextpower Inc. entered into the TRA with the LLC, Yuma, Yuma Sub, TPG Rise and the TPG Affiliates. The TRA provides for the payment by Nextpower Inc. to Yuma, Yuma Sub, TPG and the TPG Affiliates (or certain permitted transferees thereof) of 85% of the tax benefits, if any, that Nextpower Inc. is deemed to realize under certain circumstances as a result of (i) its allocable share of existing tax basis in tangible and intangible assets resulting from exchanges or acquisitions of outstanding Series A Preferred Units or common units of the LLC (collectively, the “LLC Units”), including as part of the Transactions or under the Exchange Agreement, (ii) increases in tax basis resulting from exchanges or acquisitions of LLC Units and shares of Nextpower Inc.’s Class B common stock (including as part of the Transactions or under the Exchange Agreement), (iii) certain pre-existing tax attributes of certain blocker corporations affiliated with TPG Rise that each merged with a separate direct, wholly-owned subsidiary of Nextpower Inc., as part of the Transactions, and (iv)
certain other tax benefits related to Nextpower Inc. entering into the TRA, including tax benefits attributable to payments under the TRA. Prior to the Spin-off, Yuma and Yuma Sub assigned their respective rights under the TRA to an entity that remains an affiliate of the former parent.
As of March 31, 2026 and 2025, a liability of $393.2 million and $419.4 million, respectively, was recorded for the expected amount to be paid to the affiliate of the former parent, TPG and the TPG affiliates, of which $372.7 million and $394.9 million, respectively, were included in TRA liabilities and $20.5 million and $24.5 million, respectively, were included in other current liabilities on the consolidated balance sheets.
Pillar Two
The Organization for Economic Co-operation and Development ("OECD"), a global policy forum, issued Pillar Two Global Anti-Base Erosion rules, which a global minimum tax of 15% would apply to multinational groups with consolidated financial statement revenue in excess of EUR 750 million. The Company has evaluated the impact of these rules and currently believes that it will not have a material impact on its financial results through 2026.
As many countries have proposed or enacted Pillar Two in jurisdictions in which the Company operates, the Company continues to monitor the relevant developments.
Tax distributions
During fiscal years 2026, 2025 and 2024 and pursuant to the LLC Agreement, the LLC made pro rata tax distributions cash payment to its former non-controlling interest holders in the aggregate amount of approximately $3.0 million, $6.1 million, and $66.9 million, respectively.
