Jun. 30, 2025

The accompanying condensed consolidated interim financial statements have been prepared on the basis of accounting principles generally accepted in the United States of America (“U.S. GAAP”). The condensed consolidated interim financial statements include the accounts of the Company and all entities in which it holds a controlling financial interest. All intercompany balances and transactions have been eliminated.

We have prepared the accompanying unaudited condensed consolidated interim financial statements in accordance with the accounting policies described in GDH LP’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2024 and the interim reporting requirements of Regulation S-X for the three and six months ended June 30, 2025. Accordingly, certain information and note disclosures normally

included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These unaudited condensed consolidated interim financial statements should be read in conjunction with GDH LP’s audited consolidated financial statements for the year ended December 31, 2024. The Company’s interim results are not necessarily indicative of its results for a full year.

Change in Presentation

Certain comparative figures in the Company’s condensed consolidated interim statements of operations have been reclassified to conform to the current year’s presentation.

Noncontrolling Interests

The Company, as holder of LP Units and sole general partner of GDH LP, has both (i) the power to direct GDH LP’s most significant activities; and (ii) the obligation to absorb losses or the right to receive benefits that could be significant to GDH LP. The limited partnership interests in GDH LP that are not owned by the Company are presented as noncontrolling interests in the Company’s consolidated financial statements.

The noncontrolling interests were initially measured at the proportional share of equity held by the noncontrolling interest holders on the date of the Reorganization Transaction, May 13, 2025. Each reporting period, the noncontrolling interests are adjusted for (i) the noncontrolling interest holders’ share of GDH LP’s net income / (loss) based on their relative ownership and (ii) distributions declared.

Each LP Unit of GDH LP that represents a noncontrolling interest in the Company corresponds with a share of Class B common stock of the Company. Each share of Class B common stock, along with its paired LP Unit, are together exchangeable for a share of Class A common stock on a 1:1 basis. Such exchanges increase the Company’s ownership of GDH LP and are accounted for as equity transactions.

Because the noncontrolling interests held through LP Units are economically equivalent to shares of Class A common stock, diluted EPS is calculated using the if-converted method, assuming all noncontrolling interests were exchanged for shares of Class A common stock as of the beginning of each period.

Change in Presentation

Certain comparative figures in the Company’s condensed consolidated interim statements of operations have been reclassified to conform to the current year’s presentation.
