Subsequent Event [Line Items]
Subsequent Events	Subsequent Events On April 1, 2026, the Company’s Class A common stock, par value $0.01 per share (“Class A common stock”), began trading on The Nasdaq Global Select Market under the symbol “HMH.” On April 2, 2026, the Company completed its IPO of 10,520,000 shares of its Class A common stock at a price to the public of $20.00 per share. The net proceeds from the IPO were approximately $197.8 million, after deducting the underwriters’ discounts and offering fees of $12.9 million. The Company also granted the IPO underwriters a 30-day option to purchase up to 1,578,000 additional shares of Class A common stock on the same terms. The underwriters partially exercised the option on April 30, 2026 and, on May 5, 2026, purchased 685,844 additional shares of Class A common stock, resulting in additional net proceeds of $12.9 million, after deducting the underwriters’ discounts and offering fees of $0.8 million. HMH B.V. has recognized IPO-related costs of $26.1 million and $21.3 million as of March 31, 2026 and December 31, 2025, respectively, reflected in Prepaids and other current assets on HMH B.V.’s Condensed Consolidated Balance Sheets. The Company will use net proceeds from the IPO to reimburse HMH B.V. for these costs. Corporate Reorganization The Company used approximately $39.5 million of the net proceeds from the IPO as the cash consideration to purchase an aggregate of 2,100,000 voting Class A ordinary shares of HMH B.V. (“B.V. Voting Class A Shares”) and 2,100,000 voting Class B ordinary shares of HMH B.V. (“B.V. Voting Class B Shares” and, together with B.V. Voting Class A Shares, the “B.V. Voting Shares”) from Baker Hughes Holdings LLC, a wholly owned subsidiary of Baker Hughes Company (together with Baker Hughes Holding LLC, “Baker Hughes”), and Akastor AS and Mercury HoldCo Inc., wholly owned subsidiaries of Akastor ASA (together with Akastor AS, Mercury HoldCo Inc. and Mercury HoldCo AS, “Akastor”). Baker Hughes and Akastor are collectively referred to as the “Principal Stockholders”. On April 2, 2026, the Company contributed all of the remaining net proceeds from the IPO to HMH B.V. in exchange for a number of B.V. Voting Class A Shares and B.V. Voting Class B Shares such that the number of B.V. Voting Class A Shares and B.V. Voting Class B Shares, respectively, held by the Company, taking into account the B.V. Voting Class A Shares and B.V. Voting Class B Shares acquired by the Company from the Principal Stockholders, equals the number of shares of Class A common stock sold by the Company in the IPO. On May 5, 2026, the Company contributed all of the net proceeds from the underwriters’ exercise of the over-allotment option to HMH B.V. in exchange for an additional 685,844 B.V. Voting Class A Shares and 685,844 B.V. Voting Class B Shares. HMH B.V. used such additional net proceeds to purchase in equal proportion from Baker Hughes and Akastor, respectively, an aggregate number of shares of the Company’s Class B common stock, par value $0.01 per share (“Class B common stock”), non-voting Class A ordinary shares of HMH B.V. (“B.V. Non-Voting Class A Shares”) and non-voting Class B ordinary shares of HMH B.V. (“B.V. Non-Voting Class B Shares” and, together with the B.V. Non-Voting Class A Shares, the “B.V. Non-Voting Shares”), respectively, equal to the number of shares of Class A common stock purchased by the underwriters pursuant to the exercise of the option. As a result of these transactions on April 2, 2026, the Company owns 100% of the B.V. Voting Shares and will consolidate HMH B.V. and its subsidiaries. After giving effect to these transactions, including the shares of Class A common stock issuable upon the consummation of the IPO pursuant to equity awards that vested in connection with the IPO, Baker Hughes and Akastor each owned 15,945,826 shares of the Company’s Class B common stock, par value $0.01 per share (“Class B common stock”), collectively representing approximately 72% of the total voting power of the Company’s capital stock, and each owned 15,945,826 non-voting Class A ordinary shares of HMH B.V. (“B.V. Non-Voting Class A Shares”) and 15,945,826 non-voting Class B ordinary shares of HMH B.V. (“B.V. Non-Voting Class B Shares”, and together with the B.V. Non-Voting Class A Shares, the “B.V. Non-Voting Shares”), collectively representing an approximately 72% equity interest in HMH B.V. and 0% voting power of the equity in HMH B.V. Immediately following the underwriters’ exercise of the over-allotment option, the investors in the IPO, collectively, owned all of the shares of the Company’s Class A common stock, representing approximately 28% of the total voting power of the Company’s capital stock. Tax Receivable Agreement On April 2, 2026, the Company entered into a Tax Receivable Agreement (the “TRA”) with HMH B.V. and the Principal Stockholders. The TRA requires the Company to pay 85% of the net cash savings, if any, actually realized or deemed to be realized in certain circumstances to the Principal Stockholders in connection with U.S. federal, state, local and foreign income taxes and franchises taxes resulting from (i) acquisitions of B.V. Voting Shares from the Principal Stockholders by the Company in connection with the IPO, (ii) the acquisition of B.V. Non-Voting Shares from the Principal Stockholders using the net proceeds from any future offering, (iii) redemptions or exchanges of B.V. Non-Voting Shares by the Principal Stockholders and the corresponding number of shares of the Company’s Class B common stock for shares of the Company’s Class A common stock or cash or (iv) tax benefits related to imputed interest deemed arising as a result of payments made under the TRA. In the second quarter of 2026, the Company expects to record a TRA liability in the amount of approximately $3.8 million. The Company expects to record a full valuation allowance on the deferred tax asset, resulting from difference between the book and tax basis of the Company’s investment in HMH B.V. which is expected to be realized over the useful life of the underlying assets acquired. A full valuation allowance is expected to be established as the Company believes it is more likely than not that all or a portion of these deferred tax assets will not be realized in future.

Subsequent Events	Subsequent Events On April 2, 2026, HMH Holding completed its IPO of shares of its Class A common stock and received net proceeds of approximately $197.8 million after deducting the underwriters’ discounts and offering fees of $12.6 million. HMH Holding also granted the IPO underwriters a 30-day option to purchase additional shares of Class A common stock on the same terms. On April 30, 2026, the underwriters partially exercised the option, resulting in additional net proceeds of $12.9 million, after deducting the underwriters’ discounts and offering fees of $0.8 million. HMH Holding used approximately $39.5 million of the net proceeds it received from the IPO as the cash consideration to purchase an aggregate of 2,100,000 of our voting Class A ordinary shares (“B.V. Voting Class A Shares”) and 2,100,000 of our voting Class B ordinary shares (“B.V. Voting Class B Shares” and, together with B.V. Voting Class A Shares, the “B.V.

Voting Class B Shares acquired by HMH Holding from the Principal Stockholders, equals the number of shares of Class A common stock sold by HMH Holding in the IPO. We used the remaining net proceeds received from the IPO to repay all of the outstanding principal and accrued and unpaid interest under a loan agreement with Baker Hughes Holdings LLC and Akastor AS, dated as of October 1, 2021 (as amended, the “Shareholder Loans”), net of amounts owed to the Company by Baker Hughes and Akastor, respectively, pursuant to that certain note with Baker Hughes and Akastor dated March 17, 2023, as amended, and remaining proceeds were used to fund our working capital.

Non-Voting Class A Shares”) and non-voting Class B ordinary shares of the Company (“B.V. Non-Voting Class B Shares” and, together with the B.V. Non-Voting Class A Shares, the “B.V. Non-Voting Shares”), respectively, equal to the number of shares of Class A common stock purchased by the underwriters pursuant to the exercise of the option. After giving effect to these transactions, including the shares of Class A common stock issuable upon the consummation of the IPO pursuant to equity awards that vested in connection with the IPO, Baker Hughes and Akastor each owned 15,945,826 shares of HMH Holding’s Class B common stock, par value $0.01 per share (“Class B common stock”), collectively representing approximately 72% of the total voting power of HMH Holding’s capital stock, and each owned 15,945,826 B.V.

Earnings Per Share, Basic, by Common Class, Including Two Class Method [Line Items]

Earnings per Share

For purposes of calculating earnings per share, Class A ordinary shares and Class B ordinary shares are identical. Therefore, the Company has calculated basic earnings per share on the basis of 200 shares. Basic earnings per ordinary share is calculated by dividing the net income attributable to the Company during the period by the weighted average number of ordinary shares outstanding during the same period. There are no adjustments required to be made to net income or the ordinary shares outstanding for purposes of computing basic and diluted earnings per share.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The Company’s condensed balance sheets have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). As there has been no operating activity for the Company since its inception through March 31, 2026, separate condensed statements of income, comprehensive income, cash flows and changes in stockholder’s equity have not been presented. The Company’s year-end is December 31. The preparation of financial statements in accordance with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, related revenues and expenses and the disclosure of gain and loss contingencies at the date of the financial statements and during the periods presented. The Company bases these estimates on historical results and various other assumptions believed to be reasonable, all of which form the basis for making estimates concerning the carrying values of assets and liabilities that are not readily available from other sources. Actual results could differ materially from those estimates. Offering Costs In connection with the Company’s initial public offering (“IPO”), affiliates of the Company have or will incur accounting, legal and other costs, which will be reimbursed by the Company upon consummation of the IPO. Such costs will be deferred and recorded as a reduction to stockholder’s equity and recorded against the proceeds from the IPO.

Commitment and Contingencies

Commitments and Contingencies

We are involved in various claims and legal actions arising in the ordinary course of business. A liability is recognized in our consolidated financial statements when a loss is considered probable and amounts can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, we will disclose the nature of the claim and, if possible, an estimate of the loss or range of loss. We believe it is remote that outcomes of such known matters would have a material adverse impact on our consolidated financial position, result of operations or liquidity.

Restructuring

The Company has taken a substantial workforce decrease and reorganization in recent years, driven by the desire to increase efficiency and flexibility and rationalize its footprint, which involved establishing a new organization structure by converting the “Major Projects and Products” division under ESS to “Product and Innovation, Engineering Disciplines and Product Management.” In January 2025, the Company also announced a restructuring plan primarily focused on the reorganization of facilities in Horten and Fornebu, Norway and global workforce reductions. These initiatives impacted 135 individuals, comprising 110 employees in Norway and 25 employees in Germany.

For the three months ended March 31, 2025, we recognized restructuring and other expenses of $3.3 million, which included a charge of $1.1 million related to the impairment of right-of-use assets. There were no restructuring and other expenses recognized in the three months ended March 31, 2026.

The following table summarizes the changes to the Company’s provision balance for restructuring and other charges:


	March 31, 2026

	(in thousands)
Balance at the beginning of the period	$	2,085

Reductions for payments	(308)
Foreign currency translation	(10)
Balance at the end of period	$	1,767

Other

In the normal course of business with customers, vendors and others, the Company has issued various bank guarantees, such as advance payment guarantees, surety bonds, performance guarantees, bid bonds, customs and tax guarantees to guarantee the Company’s performance as it relates to contracts with customers, contract bidding, customs duties, tax appeals and obligations in various jurisdictions. As of March 31, 2026, the Company had outstanding bank guarantees of $29.1 million. As of March 31, 2026, none of these guarantees either has, or is likely to have, a material impact on the Company’s financial position, results of operations or cash flows as the Company expects to comply with the underlying performance requirements.

Segment Reporting [Line Items]

Segment Information

Operating segments are defined as components of an entity for which separate financial information is available and evaluated on a regular basis by the Chief Operating Decision Maker (“CODM”) to allocate resources and assess performance. As of March 31, 2026 and 2025, the Company had two operating segments, ESS and PCS. The Company has identified its reportable segments based on the nature of the products and services, markets served and pricing and go-to-market strategies.

•ESS is a supplier of drilling solutions and complete topside drilling packages and services to both onshore and offshore oil and gas customers. Key product offerings consist of overhaul, equipment installation and commissioning, services account management, 24/7 technical support, logistics, engineering upgrades, spare parts supply and training and condition-based maintenance. The ESS segment is derived from the acquisition of MHWirth AS.

•PCS is a supplier of integrated drilling products and services. Key product offerings consist of blowout preventer systems, controls and drilling riser equipment, spare parts supply for rig operations and maintenance programs, overhaul and recertification and reactivation of rigs and technical and operational rig support. The PCS segment is derived from the acquisition of Subsea Drilling Systems.

In addition to its reportable segments, the Company has corporate operations (Headquarters) which include general corporate expenses. Headquarters includes certain corporate stewardship items discussed below necessary to reconcile the reportable segments to the Company’s total amounts.

The CODM, who is the Company’s Chief Executive Officer, uses segment operating income as the primary financial measure to evaluate segment performance. Segment operating income is defined as income before taxes (excluding certain corporate stewardship costs which are not allocable to the segments, such as legal, certain corporate finance functions and centrally managed initiatives, other non-operating items, and depreciation and amortization related to certain long-lived assets, including the headquarters office space), net other operating expenses (income), net foreign currency gain/(loss), net other non-operating income (loss), and net interest income (expense). Inter-segment pricing is determined on an arm’s length basis. The CODM uses segment operating income in the budget and forecasting process and to monitor budget versus actual results, which are used in assessing the performance of the segments and to allocate resources to the segments. Segment assets are not reported to, or used by, the CODM to allocate resources to or assess performance of the Company’s segments.

The following table presents the reconciliation of reportable segment revenues:


	Three Months Ended March 31, 2026						Three Months Ended March 31, 2025
	ESS		PCS		Total		ESS		PCS		Total

	(in thousands)
Revenues from external customers	$	100,690	$	70,631	$	171,321	$	107,541	$	90,889	$	198,430
Intersegment revenue	5,249		3,619		8,868		2,118		3,232		5,350
Total segment revenue	$	105,939	$	74,250	$	180,189	$	109,659	$	94,121	$	203,780
Elimination of intersegment revenue					(8,868)						(5,350)
Total consolidated revenue					$	171,321					$	198,430

The following table presents the reconciliation of segment performance:


	Three Months Ended March 31, 2026						Three Months Ended March 31, 2025
	ESS		PCS		Total		ESS		PCS		Total

Interest expense					(6,953)						(9,179)
Income (loss) before income taxes					$	9,727					$	11,134

(a)As the CODM does not regularly review intersegment revenue, it is excluded from the determination of total segment operating income. The CODM uses revenue from external customers to assess performance and allocate resources.

(b) Restructuring and other expenses consist of severance costs primarily related to workforce reductions and reorganization within ESS and impairment of right-of-use assets.

(c) Unallocated corporate costs include certain corporate stewardship costs that are not allocable to the segments, consisting of centralized finance costs of $1.6 million for both the three months ended March 31, 2026 and 2025 and other corporate expenses of $1.6 million and $0.1 million for the three months ended March 31, 2026 and 2025, respectively.

Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Description of Business HMH Holding B.V. (“HMH,” the “Company,” “we,” “us” or “our”) is a leading global provider of offshore and onshore drilling equipment and services. The Company was operationally established with effect from October 1, 2021, through its acquisition of all shares in the MHWirth business from Akastor ASA and the Subsea Drilling Systems business from Baker Hughes Company. After these transactions, the shareholders were Baker Hughes Holdings LLC (50%), Akastor AS (25%) and Mercury HoldCo Inc. (25%). Baker Hughes Holdings LLC is a wholly owned subsidiary of Baker Hughes Company (together with Baker Hughes Holdings LLC, “Baker Hughes”), and Akastor AS and Mercury HoldCo Inc. are wholly owned subsidiaries of Akastor ASA (together with Akastor AS, Mercury HoldCo AS and Mercury HoldCo Inc., “Akastor”). HMH Holding Inc. (“HMH Holding”) was incorporated in the State of Delaware on April 29, 2024 as a holding entity with an intent to complete its initial public offering (“IPO”) and other related transactions in order to carry on our business. On April 2, 2026, HMH Holding completed its IPO of its Class A common stock, par value $0.01 per share (“Class A common stock”) and received net proceeds of approximately $197.8 million after deducting the underwriters’ discounts and offering fees of $12.6 million. HMH Holding also granted the IPO underwriters a 30-day option to purchase additional shares of Class A common stock on the same terms. On April 30, 2026, the underwriters partially exercised the option, resulting in additional net proceeds of $12.9 million, after deducting the underwriters’ discounts and offering fees of $0.8 million. Subsequent to the IPO, the Company will be consolidated by HMH Holding as HMH Holding controls 100% of the voting shares of the Company. Basis of Presentation The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These statements, therefore, should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2025 included in the final prospectus of HMH Holding dated March 31, 2026 and filed with SEC on April 1, 2026. The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q reflect all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of our consolidated financial position as of March 31, 2026 and December 31, 2025 and the consolidated results of operations and cash flows for the three months ended March 31, 2026 and 2025. The unaudited results of operations for the interim periods reported are not necessarily indicative of results to be expected for the full year. Subsequent to the IPO, HMH Holding’s sole material asset is its equity interest in the Company. As the sole managing member and holder of 100% of the voting interest of the Company, HMH Holding operates and controls all of the business and affairs of the Company. The reorganization transactions will be accounted for as a reorganization of entities under common control. Certain amounts in prior periods have been reclassified to conform with current period presentation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. Although management believes these assumptions to be reasonable, given historical experience, actual amounts and results could differ from these estimates. Estimates are used for, but are not limited to, determining the following: allowance for credit losses and inventory valuation reserves; recoverability of long-lived assets; revenue recognition on long-term contracts; valuation of goodwill; useful lives used in depreciation and amortization; income taxes and related valuation allowances; accruals for contingencies; actuarial assumptions to determine costs and liabilities related to employee benefit plans; stock-based compensation expense; valuation of derivatives; and the fair value of assets acquired and liabilities assumed in business combinations. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected. Offering Costs In connection with HMH Holding’s IPO, we and our affiliates have or will incur accounting, legal and other costs, which will be reimbursed by HMH Holding. Such costs will be deferred and recorded as a reduction to shareholders’ equity and recorded against the proceeds from the IPO. Deferred offering costs of $26.1 million and $21.3 million were recognized in Prepaids and other current assets in our Condensed Consolidated Balance Sheets as of March 31, 2026 and December 31, 2025, respectively. Concentration Risk During the three months ended March 31, 2026, two customers accounted for approximately 13.6% and 11.5% of total revenue, and three customers accounted for approximately 14.4%, 12.3% and 11.9% of total revenue during the three months ended March 31, 2025, respectively. The revenue associated with these customers were included in both Equipment and System Solutions (“ESS”) and Pressure Control Systems (“PCS”) revenue. As of March 31, 2026 and December 31, 2025, one customer accounted for approximately 15.7% and 11.2%, respectively, of current accounts receivable. The Company expects to maintain its relationship with this customer. New Accounting Standards to be Adopted As an emerging growth company (“EGC”), the Jumpstart Our Business Startups Act (the “JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The JOBS Act does not preclude an EGC from early adopting new or revised accounting standards codification. The Company has elected to use extended transition periods permissible under the JOBS Act, while also early adopting certain accounting pronouncements. The adoption dates discussed below reflect these elections. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for the Company prospectively to all annual periods beginning after December 15, 2025. The Company is currently evaluating the impact of this standard on its disclosures. In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses (Subtopic 220-40).” The ASU requires public entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, with early adoption permitted, and may be applied retrospectively. The Company is currently evaluating the impact of adopting the new ASU on its consolidated financial statements and related disclosures. In September 2025, the FASB issued ASU 2025-06, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”). Under the new guidance, internal-use software costs are capitalized when management has authorized and committed to funding the project and it is probable that the software will be completed and used for its intended function. ASU 2025-06 is effective for the Company for annual reporting periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new ASU on its consolidated financial statements and related disclosures. In November 2025, the FASB issued ASU 2025-09, “Hedge Accounting Improvements” (“ASU 2025-09”). The new guidance provides targeted improvements to the hedge accounting guidance to primarily address cash flow hedging, but also impact certain fair value and net investment hedges, including (i) permitting designation of variable price components of forecasted purchases or sales of nonfinancial assets when clearly and closely related to the underlying asset, (ii) allowing groups of forecasted transactions with similar risk exposures (including those based on different interest rate indexes) to be hedged together, and (iii) introducing a model for cash flow hedges of forecasted interest payments on “choose-your-rate” debt instruments that permits a borrower to change the designated interest rate index and/or tenor without automatically discontinuing hedge accounting. ASU 2025-09 is effective for the Company for annual reporting periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2025-09 on its consolidated financial statements and related disclosures.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2026
HMH Holding B.V. And Subsidiaries
Effective Income Tax Rate Reconciliation [Line Items]
Income Taxes	Income Taxes Provision for Income Taxes We estimate the annual effective tax rate for the full year to be applied to the actual year-to-date ordinary income and reflect the tax effects of discrete items as they occur. The tax provision for the three months ended March 31, 2026 and 2025 was $5.9 million and $5.3 million, respectively. The increase in the tax provision was primarily attributable to a change in the Company’s geographic mix of revenues. The effective tax rate for the three months ended March 31, 2026 and 2025 was 60.2% and 47.2%, respectively. Our effective tax rates for the three months ended March 31, 2026 and 2025 were impacted by valuation allowances related to losses in certain jurisdictions for which the Company cannot currently recognize a tax benefit. The effective tax rates were also impacted by certain withholding taxes, differences in tax rates in the jurisdictions in which the Company operates and the Company’s U.S. income, which is taxed at the ultimate owner level rather than at the Company level.

- Definition

The entire disclosure for income tax.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2026
Subsidiary, Sale of Stock [Line Items]
Basis of Presentation	Basis of Presentation The Company’s condensed balance sheets have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). As there has been no operating activity for the Company since its inception through March 31, 2026, separate condensed statements of income, comprehensive income, cash flows and changes in stockholder’s equity have not been presented. The Company’s year-end is December 31. The preparation of financial statements in accordance with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, related revenues and expenses and the disclosure of gain and loss contingencies at the date of the financial statements and during the periods presented. The Company bases these estimates on historical results and various other assumptions believed to be reasonable, all of which form the basis for making estimates concerning the carrying values of assets and liabilities that are not readily available from other sources. Actual results could differ materially from those estimates.
Offering Costs	Offering Costs In connection with the Company’s initial public offering (“IPO”), affiliates of the Company have or will incur accounting, legal and other costs, which will be reimbursed by the Company upon consummation of the IPO. Such costs will be deferred and recorded as a reduction to stockholder’s equity and recorded against the proceeds from the IPO.
HMH Holding B.V. And Subsidiaries
Subsidiary, Sale of Stock [Line Items]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These statements, therefore, should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2025 included in the final prospectus of HMH Holding dated March 31, 2026 and filed with SEC on April 1, 2026. The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q reflect all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of our consolidated financial position as of March 31, 2026 and December 31, 2025 and the consolidated results of operations and cash flows for the three months ended March 31, 2026 and 2025. The unaudited results of operations for the interim periods reported are not necessarily indicative of results to be expected for the full year. Subsequent to the IPO, HMH Holding’s sole material asset is its equity interest in the Company. As the sole managing member and holder of 100% of the voting interest of the Company, HMH Holding operates and controls all of the business and affairs of the Company. The reorganization transactions will be accounted for as a reorganization of entities under common control.
Offering Costs	Offering Costs In connection with HMH Holding’s IPO, we and our affiliates have or will incur accounting, legal and other costs, which will be reimbursed by HMH Holding. Such costs will be deferred and recorded as a reduction to shareholders’ equity and recorded against the proceeds from the IPO. Deferred offering costs of $26.1 million and $21.3 million were recognized in Prepaids and other current assets in our Condensed Consolidated Balance Sheets as of March 31, 2026 and December 31, 2025, respectively.
Reclassification	Certain amounts in prior periods have been reclassified to conform with current period presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. Although management believes these assumptions to be reasonable, given historical experience, actual amounts and results could differ from these estimates. Estimates are used for, but are not limited to, determining the following: allowance for credit losses and inventory valuation reserves; recoverability of long-lived assets; revenue recognition on long-term contracts; valuation of goodwill; useful lives used in depreciation and amortization; income taxes and related valuation allowances; accruals for contingencies; actuarial assumptions to determine costs and liabilities related to employee benefit plans; stock-based compensation expense; valuation of derivatives; and the fair value of assets acquired and liabilities assumed in business combinations. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected.
New Accounting Standards to be Adopted	New Accounting Standards to be Adopted As an emerging growth company (“EGC”), the Jumpstart Our Business Startups Act (the “JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The JOBS Act does not preclude an EGC from early adopting new or revised accounting standards codification. The Company has elected to use extended transition periods permissible under the JOBS Act, while also early adopting certain accounting pronouncements. The adoption dates discussed below reflect these elections. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for the Company prospectively to all annual periods beginning after December 15, 2025. The Company is currently evaluating the impact of this standard on its disclosures. In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses (Subtopic 220-40).” The ASU requires public entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, with early adoption permitted, and may be applied retrospectively. The Company is currently evaluating the impact of adopting the new ASU on its consolidated financial statements and related disclosures. In September 2025, the FASB issued ASU 2025-06, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”). Under the new guidance, internal-use software costs are capitalized when management has authorized and committed to funding the project and it is probable that the software will be completed and used for its intended function. ASU 2025-06 is effective for the Company for annual reporting periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new ASU on its consolidated financial statements and related disclosures. In November 2025, the FASB issued ASU 2025-09, “Hedge Accounting Improvements” (“ASU 2025-09”). The new guidance provides targeted improvements to the hedge accounting guidance to primarily address cash flow hedging, but also impact certain fair value and net investment hedges, including (i) permitting designation of variable price components of forecasted purchases or sales of nonfinancial assets when clearly and closely related to the underlying asset, (ii) allowing groups of forecasted transactions with similar risk exposures (including those based on different interest rate indexes) to be hedged together, and (iii) introducing a model for cash flow hedges of forecasted interest payments on “choose-your-rate” debt instruments that permits a borrower to change the designated interest rate index and/or tenor without automatically discontinuing hedge accounting. ASU 2025-09 is effective for the Company for annual reporting periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2025-09 on its consolidated financial statements and related disclosures.
