SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
Mar. 31, 2026
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These Condensed Combined Financial Statements have been derived from the consolidated financial statements and accounting records of Hexagon. These Condensed Combined Financial Statements reflect the combined historical results of operations, financial position and cash flows of the Company for the periods presented as historically operated within Hexagon in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). The Condensed Combined Financial Statements may not be indicative of the Company’s future performance and do not necessarily reflect what the financial position, results of operations, and cash flows would have been had it operated as an independent company during the periods presented. These Condensed Combined Financial Statements have been prepared on the same basis as the annual Combined Financial Statements for the three years ended December 31, 2025 included in the Information Statement attached as Exhibit 99.1 to Octave’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on May 12, 2026 (the “Information Statement”) and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The December 31, 2025 Condensed Combined Balance Sheet included herein is derived from the audited Combined Financial Statements included in the Information Statement. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results expected for the remainder of the fiscal year. These unaudited Condensed Combined Financial Statements and accompanying Notes should be read in conjunction with the audited Combined Financial Statements and accompanying Notes for the year ended December 31, 2025 included in the Information Statement. All intracompany transactions have been eliminated. All significant intercompany transactions between Octave and Parent have been included in these Condensed Combined Financial Statements. For those transactions between the Company and Parent that are historically settled in cash, the Company has reflected such balances in the Condensed Combined Balance Sheets as due from related parties or due to related parties. The total net effect of the settlement of intercompany transactions not historically settled in cash are reflected in the Condensed Combined Statements of Cash Flows as a financing activity and in the Condensed Combined Balance Sheets as Net Parent investment, with the difference between the amounts presented in the Condensed Combined Statements of Equity and the Condensed Combined Statements of Cash Flows being attributable to stock-based compensation. Historically, Hexagon provided certain corporate functions to the Company and costs associated with these functions were allocated to the Company. These functions include, but are not limited to, corporate communications, executive management, legal, human resources, treasury, finance, accounting, information technology, and the related benefit costs associated with such functions, such as stock-based compensation. The costs of such services were allocated to the Company based on direct usage when identifiable, with the remainder allocated on a pro rata basis of revenue of the Company and Hexagon. The charges for these functions are included in Sales and marketing and General and administrative expenses in the Condensed Combined Statements of Operations. The Company believes the basis on which the expenses have been allocated are a reasonable reflection of the utilization of services provided to, or the benefit received by, Octave during the periods presented; however, they may not be indicative of the actual expense that would have been incurred had the Company been operating as a standalone company for the periods presented. Actual costs that may have been incurred if the Company had been a standalone company would depend on a number of factors, including the organizational structure, pricing power, whether functions were outsourced or performed by employees, and strategic decisions made in areas such as information technology and corporate infrastructure. The Company is unable to quantify the amounts that it would have recorded during the historical periods on a standalone basis, as it is not practicable to do so. Going forward, the Company may perform these functions using its own resources or outsourced services. For an interim period, however, some of these functions may continue to be provided by the Parent under a transition services agreement following the Distribution. Hexagon utilizes a centralized treasury management function for financing its operations. The cash and cash equivalents held by Hexagon at the corporate level are not specifically identifiable to the Company and therefore have not been reflected in the Condensed Combined Balance Sheets. Cash transfers between Hexagon and the Company are accounted for through Net Parent investment. Cash and cash equivalents in the Condensed Combined Balance Sheets represent cash and cash equivalents directly identifiable to the Company and its operations. The Condensed Combined Financial Statements include certain assets and liabilities that have historically been held at the Hexagon corporate level but are specifically identifiable or otherwise attributable to the Company. Hexagon’s third-party long-term debt and the related interest expense have not been allocated to the Company for any of the periods presented as the Company was not the legal obligor of such debt and the Hexagon borrowings were not directly attributable to the Company. The income tax provision included in these Condensed Combined Financial Statements has been calculated using the separate return basis, as if the Company had filed separate tax returns.

Recent Accounting Pronouncements and Recently Adopted Accounting Standards	Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have a minimal impact on the Combined Statements of Operations, Combined Balance Sheets and Combined Statements of Cash Flows. In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 is intended to update the guidance in Topic 270 by improving navigability of the required interim disclosures, clarifying when that guidance is applicable and adding a principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for the Company for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2025-11 on its Condensed Combined Financial Statements and related disclosures. In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). The amendments in ASU 2025-06 remove the concept of development stages and introduce a principles-based model for capitalizing internal-use software costs, including those related to agile and cloud-based development. The guidance also consolidates website development costs under ASC 350-40 and enhances disclosure requirements related to software development activities. ASU 2025-06 is effective for the Company for annual reporting periods beginning after December 15, 2027, and interim periods within those annual periods, and should be applied prospectively, with optional retrospective or modified retrospective transition methods. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2025-06 on its Combined Financial Statements and related disclosures. In November 2024, FASB issued ASU No. 2024-03, Income Statements-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"), which requires enhanced disclosure of income statement expense categories to improve transparency and provide financial statement users with more detailed information about the nature, amount, and timing of expenses impacting financial performance. ASU 2024-03 is effective for the Company for the annual reporting period beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in ASU 2024-03 may be adopted either on a prospective basis to financial statements issued for reporting periods after the effective date or on a retrospective basis to all periods presented. The Company is currently evaluating the impact of the adoption of ASU 2024-03; however, other than additional disclosure, the Company does not expect a change to the Combined Financial Statements. Recently Adopted Accounting Standards In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This ASU provides entities with a practical expedient to simplify the estimation of expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606 by allowing entities to assume that current conditions as of the balance sheet date will not change over the remaining life of such assets. The Company adopted ASU 2025-05 during the three months ended March 31, 2026. The adoption did not have a material impact on the Company’s Condensed Combined Financial Statements or related disclosures.
