Note 15. Stockholders’ Equity

Business Combination

On May 8, 2026, the Company consummated the Business Combination (see Note 2 - Business Combination) which was accounted for as a reverse recapitalization, with Boost Run Holdings, LLC determined to be the accounting acquirer for financial reporting purposes. In connection with the Closing, all outstanding equity interests of Boost Run Holdings were cancelled and converted into the right to receive merger consideration in accordance with the Business Combination Agreement. As a result, no Class A Units, Class B Units or Class C Units of Boost Run Holdings remained outstanding as of September 30, 2026.

Authorized Capital Stock

As of September 30, 2026, pursuant to the Company’s Amended and Restated Certificate of Incorporation, the Company is authorized to issue 1,000,000,000 shares of capital stock, consisting of:

Class A Common Stock and Class B Common Stock

Holders of Class A Common Stock and Class B Common Stock vote together as a single class on all matters submitted to a vote of stockholders. Each share of Class A Common Stock is entitled to one vote per share, and each share of Class B Common Stock is entitled to ten votes per share. Holders of Class A Common Stock and Class B Common Stock participate equally on a per-share basis with respect to dividends and distributions and are entitled to receive ratably all assets available for distribution upon liquidation, subject to the rights of any outstanding preferred stock.

Each share of Class B Common Stock automatically converts into one share of Class A Common Stock upon certain transfers and other events specified in the Company’s Certificate of Incorporation, including (i) a transfer, assignment or other disposition of the share, (ii) the holder ceasing to serve as an executive officer or director of the Company, or (iii) the holder’s ownership of Class B Common Stock falling below 40% of the shares held by that holder at the closing of the Business Combination.

Legacy Class C Units

Prior to the Business Combination, Boost Run Holdings issued 128 Class C Units in connection with the August 2025 Warrant Cancellation Agreement. The Class C Units were non-voting interests that entitled the holder to specified economic rights in Boost Run Holdings and were subject to a participation threshold of $6,394 per unit. The Company determined that the Class C Units were appropriately classified as permanent equity because the units did not contain redemption features outside of the Company’s control.

Upon consummation of the Business Combination on May 8, 2026, all outstanding Class C Units were cancelled and converted into the right to receive shares of Boost Run Class A Common Stock in accordance with the Business Combination Agreement. Accordingly, no Class C Units remained outstanding as of September 30, 2026.

Warrants

In connection with the Business Combination, the Company assumed Public Warrants and Private Warrants previously issued by the SPAC. Each whole warrant entitles the holder to purchase one share of the Company’s Class A Common Stock at an exercise price of $11.50 per share. The warrants became exercisable upon consummation of the Business Combination and expire on May 8, 2031, unless earlier exercised, redeemed or otherwise terminated in accordance with their terms. Management evaluated the warrant terms in accordance with ASC 815, Derivatives and Hedging, and concluded that the warrants qualify for equity classification. Accordingly, the warrants are recorded within additional paid-in capital and are not subsequently remeasured.

Warrant Redemption

On July 21, 2026, the Company delivered a notice of redemption to the holders of all of its outstanding warrants to purchase Class A Common Stock, calling such warrants for redemption at 5:00 p.m., New York City time, on August 20, 2026, at a redemption price of $0.01 per warrant, in accordance with the terms of the Warrant Agreement. Prior to the redemption date, holders were able to exercise their warrants for cash at the stated exercise price of $11.50 per share; any warrants not exercised by that time were to be redeemed for $0.01 per warrant, and holders of such unexercised warrants will have no further rights with respect to those warrants other than to receive the redemption price.

During the nine months ended September 30, 2026, holders exercised all 11,447,717 warrants in connection with the redemption, respectively, for aggregate cash proceeds of approximately $131,615, recorded in the interim condensed consolidated balance sheet, which is net of approximately $34 of fees recorded in selling, general and administrative (excluding depreciation and amortization) in the interim condensed consolidated statement of operations, resulting in the issuance of 11,447,717 shares of the Company’s Class A Common Stock. As of September 30, 2026, no warrants remained outstanding.
