The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Accordingly, these interim financial statements do not include all information or footnote disclosures required by U.S. GAAP for complete financial statements and, therefore, should be read in conjunction with the Consolidated Financial Statements and notes thereto in our 2025 Annual Report on Form 10-K and other current filings with the SEC. In the opinion of management, all adjustments, consisting of those of a normal recurring nature, necessary to present fairly the results of the periods presented have been included. The results of operations for the interim periods presented may not necessarily be indicative of the results to be expected for the full year.

The Unaudited Condensed Consolidated Financial Statements include the accounts of H&P and its domestic and foreign subsidiaries. Consolidation of a subsidiary begins when the Company gains control over the subsidiary and ceases when the Company loses control of the subsidiary. Specifically, income, expenses and other comprehensive income or loss of a subsidiary acquired or disposed of during the fiscal year are included in the Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Comprehensive Income (Loss) from the date the Company gains control until the date when the Company ceases to control the subsidiary. The equity attributable to non-controlling interests in subsidiaries is shown separately in the accompanying Unaudited Condensed Consolidated Balance Sheets. All intercompany accounts and transactions have been eliminated upon consolidation.

As of June 30, 2026 and September 30, 2025, restricted cash was $34.9 million and $29.1 million, respectively. Of the total at June 30, 2026 and September 30, 2025, $33.6 million and $27.4 million, respectively, represents the amount management has elected to restrict for the purpose of potential insurance claims in our wholly-owned captive insurance companies. Additionally, of the total at September 30, 2024, $1.2 billion represents net proceeds from senior notes issued in fiscal year 2024 to finance the purchase price of the entire issued share capital (the "Acquisition") of KCA Deutag International Limited ("KCA Deutag") and to repay certain of KCA Deutag's outstanding indebtedness. These proceeds were subsequently used during the fiscal year ended September 30, 2025 to fund the Acquisition. The restricted amounts are primarily invested in short-term money market securities.


Standard	Description	Date of Adoption	Effect on the Financial Statements or Other Significant Matters



Standards that are not yet adopted as of June 30, 2026
ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures	This ASU enhances income tax disclosure requirements. Under the ASU, public business entities must annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). Specific categories that must be included in the reconciliation for each annual reporting period are specified in the amendment. This update is effective for annual periods beginning after December 15, 2024. Early adoption of the amendments is permitted. Upon adoption, the amendments shall be applied on a prospective basis. Retrospective application is permitted.	September 30, 2026	We plan to adopt this ASU, as required, during fiscal year 2026, with the first disclosure enhancements reflected in our fiscal year 2026 Form 10-K. We are currently evaluating the impact this ASU will have on our disclosures.
ASU No. 2024-03, Income Statement -- Reporting Comprehensive Income -- Expense Disaggregation Disclosure (Subtopic 220-40)	This ASU enhances disclosure requirements for certain costs and expenses. The amendments in this update enhance annual and interim disclosure requirements, certain liability-related expenses, expense reimbursements related to a cost-sharing or cost-reimbursement arrangement with another entity, and the disaggregation of relevant expense captions. This update gives entities the ability to use estimates or other methods that produce a reasonable approximation of the amounts required to be disclosed. This update is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. Upon adoption, the amendments shall be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this Update or (2) retrospectively to any or all prior periods presented in the financial statements.	September 30, 2028	We plan to adopt this ASU, as required, during fiscal year 2028 with the first disclosure enhancements reflected in our 2028 fiscal year Form 10-K. We are currently evaluating the impact the new guidance may have on our consolidated financial statements and disclosures.

We continue to use our captive insurance companies to fund the self-insured retentions ("SIRs") and deductibles for our domestic workers’ compensation, general liability, automobile liability programs, medical stop-loss program, and certain international casualty and property programs. Our operating subsidiaries are paying premiums to the Captives, typically on a monthly basis, for the estimated losses based primarily on an external actuarial analysis. These premiums are currently held in a restricted cash account, resulting in a transfer of risk from our operating subsidiaries to the Captives. These intercompany insurance premiums are reflected as segment operating expenses within the North America Solutions, International Solutions, and Offshore Solutions reportable operating segments and are reflected as intersegment sales within "Other." Intercompany premium revenues recorded by the Captives during the three months ended June 30, 2026 and 2025 amounted to $17.3 million and $16.3 million, respectively, and $55.2 million and $50.8 million during the nine months ended June 30, 2026 and 2025, respectively, which were eliminated upon consolidation. Direct operating costs consisted primarily of adjustments to accruals for estimated losses of $(3.7) million and $29.3 million during the three months ended June 30, 2026 and 2025, respectively, and $(1.6) million and $43.5 million during the nine months ended June 30, 2026 and 2025, respectively, and rig and casualty insurance premiums of $12.6 million and $10.1 million during the three months ended June 30, 2026 and 2025, respectively, and $35.9 million and $31.8 million during the nine months ended June 30, 2026 and 2025, respectively. Our medical stop loss operating expenses for the three months ended June 30, 2026 and 2025 were $4.8 million and $4.4 million, respectively, and $11.5 million and $14.8 million for the nine months ended June 30, 2026 and 2025, respectively. These operating costs were recorded within Drilling services operating expenses in our Unaudited Condensed Consolidated Statements of Operations.

The reporting and functional currency of the parent company, H&P, is the United States Dollar ("USD"). Our foreign subsidiaries are measured using the currency of the primary economic environment in which the entity operates (the functional currency). For some of our foreign subsidiaries, functional currency is not measured in U.S. Dollars, and, instead, is the local currency. On consolidation, the assets and liabilities of our non U.S. Dollar functional entities are translated at exchange rates in effect at the balance sheet date. Revenue and expenses are translated at the average exchange rates prevailing during the reporting period. Translation adjustments are recorded as a separate component of stockholders’ equity and are included in Other comprehensive income or loss on the Unaudited Condensed Consolidated Statements of Comprehensive Income (Loss).

International drilling operations may significantly contribute to our revenues and net operating income (loss). There can be no assurance that we will be able to successfully conduct such operations, and a failure to do so may have an adverse effect on our financial position, results of operations, and cash flows. Also, the success of our international operations will be subject to numerous contingencies, some of which are beyond management’s control. These contingencies include general and regional economic conditions, geopolitical developments and tensions, war and uncertainty in oil-producing countries, fluctuations in currency exchange rates, foreign currency exchange restrictions and other difficulties repatriating cash from foreign countries, changes in international regulatory requirements and international employment issues, risk of expropriation of real and personal property and the burden of complying with foreign laws. Additionally, in the event that extended labor strikes occur or a country experiences significant political, economic or social instability, we could experience shortages in labor and/or material and supplies necessary to operate some of our drilling rigs, thereby potentially causing an adverse material effect on our business, financial condition and results of operations.

Because of the impact of local laws, some of our current operations and potential future operations in certain areas may be conducted through entities in which local citizens own interests. Additionally, these operations might involve entities (including joint ventures) where we hold only a minority interest or where operations are carried out under contracts with local entities. While we believe that neither operating through such entities nor pursuant to such arrangements would have a material adverse effect on our operations or revenues, there can be no assurance that we will in all cases be able to structure or restructure our operations to conform to local law (or the administration thereof) on terms acceptable to us.

Approximately 42.7 percent and 41.7 percent of our operating revenues were generated from international locations during the three and nine months ended June 30, 2026 compared to 36.7 percent and 31.4 percent during the three and nine months ended June 30, 2025, respectively. Although we attempt to minimize the potential impact of such risks by operating in more than one geographical area, approximately 15.7 percent and 16.2 percent of our total consolidated operating revenues were from operations in the Middle East during the three and nine months ended June 30, 2026 compared to 16.1 percent and 13.2 percent during the three and nine months ended June 30, 2025, respectively. The majority of our operating revenues in the Middle East were from operations in Saudi Arabia and Oman. During the three and nine months ended June 30, 2026, a single customer in Saudi Arabia accounted for 7.2 percent and 6.9 percent of our total consolidated operating revenues, compared to 10.0 percent and 7.4 percent during the three and nine months ended June 30, 2025. This customer has the ability to suspend rigs and a portion of our rigs with this customer are currently suspended. The future occurrence of one or more international events arising from the types of risks described above could have a material adverse impact on our business, financial condition and results of operations.
