Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Basis of Presentation	Background and Basis of Presentation Hillenbrand, Inc. (the “Company” or “Hillenbrand”) is a global industrial company that provides highly-engineered processing equipment and solutions to customers around the world. Our portfolio is composed of leading industrial brands that serve large, attractive end markets, including durable plastics, food, and recycling. Guided by our Purpose, Shape What Matters for TomorrowTM, we pursue excellence, collaboration, and innovation to shape solutions that best serve our people, our customers, and our communities. Customers choose Hillenbrand due to our reputation for designing, manufacturing, and servicing highly-engineered, mission-critical equipment and solutions that meet their unique and complex processing requirements. Hillenbrand is composed of two reportable operating segments: Advanced Process Solutions and Molding Technology Solutions. Advanced Process Solutions is a leading global provider of highly-engineered process and material handling equipment, systems, and aftermarket parts and services for a variety of industries, including durable plastics, food, and recycling. Molding Technology Solutions is a global leader in highly-engineered equipment, systems, and aftermarket parts and service for the plastic technology processing industry. Molding Technology Solutions has a comprehensive product portfolio that includes injection molding and extrusion equipment, hot runner systems, process control systems, mold bases and components, and maintenance, repair, and operating (“MRO”) supplies. The Consolidated Financial Statements include the accounts of Hillenbrand and its subsidiaries. They also include three subsidiaries where the Company’s ownership percentage is less than 100%. The Company’s fiscal year ends on September 30. Unless otherwise stated, references to years refer to fiscal years. These unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements and therefore do not include all information required in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The unaudited Consolidated Financial Statements have been prepared on the same basis as, and should be read in conjunction with, the audited Consolidated Financial Statements and notes thereto included in the Company’s latest Annual Report on Form 10-K for the year ended September 30, 2025, as filed with the SEC on November 19, 2025. In the opinion of management, these unaudited Consolidated Financial Statements reflect all adjustments necessary to present a fair statement of the Company’s consolidated financial position and the consolidated results of operations and cash flows as of the dates and for the periods presented and are normal and recurring in nature. The interim period results are subject to variation and are not necessarily indicative of the consolidated results of operations to be expected for the full fiscal year. The preparation of the Consolidated Financial Statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of net revenue and expenses during the period. Actual results could differ from those estimates. Examples of such estimates include, but are not limited to, revenue recognition under the over time method, establishment of reserves related to credit losses, warranties, income taxes, litigation, and self-insurance. Acquisition by Lone Star As announced on October 15, 2025, on October 14, 2025, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with LSF12 Helix Parent, LLC, a Delaware limited liability company (“Parent”), and LSF12 Helix Merger Sub, Inc., an Indiana corporation and a wholly owned subsidiary of Parent (“Merger Sub”), providing for the merger of Merger Sub with and into Hillenbrand (the “Merger”), with Hillenbrand surviving the Merger as a wholly owned subsidiary of Parent. Parent and Merger Sub are affiliates of Lone Star Funds XII, L.P. At the effective time of the Merger, on the terms and subject to the conditions set forth in the Merger Agreement, each share of the Company’s common stock issued and outstanding immediately prior to such time, other than shares of the Company’s common stock owned by Hillenbrand, any wholly owned subsidiary of Hillenbrand, Parent, Merger Sub or any other wholly owned subsidiary of Parent (each of which will be cancelled), will be converted into the right to receive $32.00 in cash, without interest. The transactions contemplated by the Merger Agreement were unanimously approved by Hillenbrand’s Board of Directors, and Hillenbrand’s shareholders voted to approve the Merger Agreement at a special meeting of the Company’s shareholders on January 8, 2026. The Merger is expected to close by the end of the first quarter of calendar year 2026, subject to customary closing conditions.
