Divestitures	Divestitures Batesville As previously described, on February 1, 2023, the Company completed the divestiture of Batesville to BL Memorial Partners, LLC, a Delaware limited liability company owned by funds affiliated with LongRange Capital, L.P., for $761.5, including an $11.5 subordinated note. At closing, after the applicable adjustments, the Company received $698.0 in pre-tax cash proceeds, including an adjustment for cash on hand acquired from the Company, and the previously mentioned subordinated note. This divestiture represented a strategic shift in Hillenbrand’s business and qualified as a discontinued operation. Accordingly, the operating results and cash flows related to Batesville have been reflected as discontinued operations in the Consolidated Statements of Operations and the Consolidated Statements of Cash Flows for all periods presented. The Company recognized a $586.0 pre-tax gain on divestiture, recorded within gain on divestiture of discontinued operations (net of income tax expense) in the Consolidated Statement of Operations for the year ended September 30, 2023. Certain indirect corporate costs included within operating expenses in the Consolidated Statements of Operations that were previously allocated to Batesville do not qualify for classification within discontinued operations and are now reported as operating expenses in continuing operations within corporate expenses. In addition, costs directly attributable to Batesville have been reflected in discontinued operations. As a result, income before income taxes of Batesville decreased $16.0 and $3.1 for the years ended September 30, 2023 and 2022, respectively. Discontinued operations Components of amounts reflected in the Consolidated Statements of Operations related to discontinued operations are presented in the table, as follows: Year Ended September 30, 2024 2023 2022 Net revenue $ — $ 213.7 $ 625.6 Cost of goods sold — 142.2 434.8 Gross profit — 71.5 190.8 Operating expense 1.1 42.3 76.4 Income from discontinued operations before income taxes (1.1) 29.2 114.4 Income tax (benefit) expense (3.3) 9.7 14.9 Income from discontinued operations (net of income tax (benefit) expense) 2.2 19.5 99.5 Gain on divestiture of discontinued operations (1) — 443.1 — Total income from discontinued operations $ 2.2 $ 462.6 $ 99.5 (1)

Business Combinations [Abstract]
Acquisitions	Acquisitions Acquisition of Schenck Process Food and Performance Materials Business On September 1, 2023, the Company completed its acquisition of Schenck Process Food and Performance Materials (“FPM”) for $763.3, including cash acquired, which consisted of $748.7 in consideration paid at the acquisition date, plus contingent consideration of $14.6. The contingent consideration of $14.6 reflects the estimated fair value, as of the date of acquisition, of contingent future cash payments based on the value of certain research and development tax credits that were generated by FPM prior to the acquisition date, which is included in other long-term liabilities on the Consolidated Balance Sheets. The value of these credits, and therefore the payment of the contingent consideration, is subject to audit by the tax authorities and to the closing of the statute of limitations for the year in which the tax credits are fully utilized, the timing of which is not able to be determined at this time, but we expect to extend several years. There have been no changes in the estimated fair value of the initial calculation of the contingent consideration during the year ended September 30, 2024. The Company used available borrowings under its multi-currency revolving credit facility (the “Facility”) to fund the cash consideration portion of this acquisition. Headquartered in Kansas City, Missouri, FPM specializes in the design, manufacturing, and service of feeding, filtration, baking, and material handling technologies and systems that are highly complementary to the equipment and solutions offered in our Advanced Process Solutions reportable operating segment. The results of FPM since the date of the acquisition are included in the Advanced Process Solutions reportable operating segment. As of August 1, 2024, the FPM business has been rebranded under Hillenbrand's existing Coperion brand. Purchase price allocation and other items The Company utilized the services of an independent valuation consultant, along with estimates and assumptions determined by management, to estimate the fair value of the assets acquired and liabilities assumed. The allocation of the purchase price was based on an evaluation of the appropriate fair values and represents management’s best estimate based on available data. The following table summarizes the final fair values of the assets acquired and liabilities assumed as of the acquisition date: September 1, 2023 (as initially reported) Measurement Period Adjustments September 1, 2023 (as adjusted) Assets acquired: Cash and cash equivalents $ 17.3 $ — $ 17.3 Trade receivables 65.2 (8.7) 56.5 Receivables from long-term manufacturing contracts 22.4 — 22.4 Inventories 64.8 1.8 66.6 Prepaid expenses and other current assets 10.3 (0.3) 10.0 Property, plant, and equipment 27.3 14.6 41.9 Operating lease right-of-use assets 11.0 3.1 14.1 Intangible assets 338.0 2.0 340.0 Goodwill 476.5 (1.6) 474.9 Other non-current assets 2.7 3.2 5.9 Total assets acquired 1,035.5 14.1 1,049.6 Liabilities assumed: Trade accounts payable 59.4 (2.3) 57.1 Liabilities from long-term manufacturing contracts 86.6 11.0 97.6 Accrued compensation 13.5 — 13.5 Other current liabilities 45.7 (1.0) 44.7 Accrued pension and postretirement healthcare — 2.2 2.2 Operating lease liabilities 9.5 — 9.5 Deferred income taxes 69.0 (19.4) 49.6 Other non-current liabilities 3.1 9.0 12.1 Total liabilities assumed 286.8 (0.5) 286.3 Net assets acquired $ 748.7 $ 14.6 $ 763.3 Measurement period adjustments The preliminary purchase price allocation was based upon a preliminary valuation, and the Company’s estimates and assumptions were subject to change within the measurement period (defined as one year following the acquisition date). As a result of further refining its estimates and assumptions since the date of the acquisition, the Company recorded measurement period adjustments to the initial opening balance sheet as shown in the table above. Adjustments were primarily made to property, plant, and equipment, deferred income taxes, liabilities from long-term manufacturing contracts, other non-current liabilities, trade receivables, goodwill, and other non-current assets. There were no measurement period adjustments materially impacting earnings that would have been recorded in previous reporting periods if the adjustments had been recognized as of the acquisition date. During the year ended September 30, 2024, the purchase price allocation for the acquisition was finalized. Intangible assets identified The purchase price allocation included $340.0 of acquired identifiable intangible assets. Intangible assets primarily consist of FPM’s technology and customer relationships and are being amortized on a straight-line basis over the respective estimated periods for which the intangible assets will provide economic benefit to the Company. The determination of the useful lives was based upon various industry studies, historical acquisition experience, degree of stability in the current FPM customer base, economic factors, and expected future cash flows of the Company following the acquisition of FPM. The technology was valued using the relief-from-royalty method of the income approach. Customer relationships were valued using the multi-period excess earnings method of the income approach. Significant assumptions used in the valuations included FPM’s future cash flow projections, which were based on estimates used to price the FPM acquisition, discount rates that were benchmarked with reference to the implied rate of return to the Company’s pricing model, and the applicable weighted-average cost of capital (12%). The amounts allocated to intangible assets are as follows: Gross Carrying Amount Weighted-Average Useful Life Customer relationships $ 285.0 15 years Technology 49.0 12 years Trade name 5.0 5 years Other 1.0 6 years Total intangible assets $ 340.0 Goodwill was calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The factors contributing to the recognition of goodwill were based on strategic benefits that are expected to be realized from the acquisition. None of the goodwill is deductible for income tax purposes. The working capital assets and liabilities were valued using Level 2 inputs, which included data points that are observable, such as definitive sales agreements, appraisals or established market values of comparable assets (market approach). Goodwill and identifiable intangible assets were valued using Level 3 inputs, which are unobservable by nature, and included internal estimates of future cash flows (income approach). Significant increases (decreases) in any of those unobservable inputs in isolation would result in a significantly lower (higher) fair value measurement. Management used a third-party valuation firm to assist in the determination of the preliminary purchase accounting fair values, specifically those considered Level 3 measurements. Management ultimately oversees the third-party valuation firm to ensure that the transaction-specific assumptions are appropriate for the Company. Impact on consolidated results of operations The results of FPM’s operations have been included in Hillenbrand’s Consolidated Financial Statements since the September 1, 2023, acquisition date. The following table provides the results of operations for FPM included in Hillenbrand’s Consolidated Statement of Operations: Year Ended September 30, 2024 2023 Net revenue $ 535.7 $ 43.3 Income from continuing operations before income taxes 58.7 3.4 During the years ended September 30, 2024 and 2023, the Company incurred $0.4 and $16.2, respectively, in acquisition expenses related to the FPM acquisition, which are included in operating expenses in the Consolidated Statement of Operations. Acquisition of Peerless Food Equipment On December 1, 2022, the Company completed the acquisition of Peerless for a purchase price of $59.2, net of certain customary post-closing adjustments and including cash acquired, using available borrowings under the Facility. Headquartered in Sidney, Ohio, Peerless is a premier supplier of industrial food processing equipment. The acquisition of Peerless increased the Company’s scale in the food end market, and combining Peerless’ highly complementary equipment and solutions with other Advanced Process Solutions reportable operating segment technologies now allows the Company to deliver more comprehensive solutions to its customers. The purchase price allocation was finalized during the year ended September 30, 2024 with no material purchase price adjustments recognized. The results of Peerless since the date of acquisition are included in the Advanced Process Solutions reportable operating segment. Acquisition of LINXIS Group SAS On October 6, 2022, the Company completed the acquisition of Linxis from IBERIS INTERNATIONAL S.À R.L, an affiliate of IK Partners, and additional sellers (collectively, the “Sellers”). As a result of the acquisition, the Company acquired from the Sellers all of the issued and outstanding securities of Linxis, and Linxis became a wholly owned subsidiary of the Company for total aggregate consideration of $590.8 (€596.2) in cash, reflecting an approximate enterprise value of $566.8 (€572.0) plus cash acquired at closing. The Company used available borrowings under the Facility to fund this acquisition. Linxis has six market-leading brands – Bakon, Diosna, Shaffer, Shick Esteve, Unifiller, and VMI – that serve customers in over one hundred countries. With a global manufacturing, sales and service footprint, Linxis specializes in design, manufacturing, and service of dosing, kneading, mixing, granulating, drying, and coating technologies. The results of Linxis since the date of acquisition are included in the Advanced Process Solutions reportable operating segment. Supplemental Pro Forma Information The supplemental pro forma financial information presented below is for illustrative purposes only and is not necessarily indicative of the financial position or results of operations that would have been realized if the FPM, Peerless, Linxis, and other individually immaterial acquisitions had been completed on the date indicated, do not reflect synergies that might have been achieved, and are not indicative of future results of operations or financial position. The pro forma adjustments are based upon currently available information and certain assumptions that Hillenbrand believes are reasonable under the circumstances. The supplemental pro forma financial information reflects pro forma adjustments to present the combined pro forma results of operations as if the acquisitions of FPM, Peerless, Linxis, and other individually immaterial acquisitions had occurred on October 1, 2021, to give effect to certain events that Hillenbrand believes to be directly attributable to the acquisitions. These pro forma adjustments primarily include: • an increase to depreciation and amortization expense that would have been recognized due to acquired tangible and intangible assets; • an adjustment to interest expense to reflect the additional borrowings of Hillenbrand and the repayment of Linxis’s historical debt in conjunction with the acquisition; • an adjustment to remove business acquisition and integration costs and inventory step-up costs during the years ended September 30, 2023 and 2022, as these costs are non-recurring in nature and would not have a continuing effect on Hillenbrand’s consolidated results of operations; and • the related income tax effects of the adjustments noted above. The supplemental pro forma financial information for the periods presented is as follows: Year Ended September 30, 2023 2022 Net revenue $ 3,331.3 $ 3,241.4 Income from continuing operations attributable to Hillenbrand 137.7 111.3 Income from continuing operations attributable to Hillenbrand — per share of common stock: Basic earnings per share from continuing operations $ 1.97 $ 1.55 Diluted earnings per share from continuing operations $ 1.96 $ 1.54

The lease has an initial term of 20 years with four additional renewal terms of five years each at the option of the Company. In the Company’s lease classification assessment, only the initial term was used as it was not determined to be reasonably probable that the Company would exercise the extensions as of September 30, 2024. The Company received net proceeds of $53.7 and recognized a gain of $33.7, which is included in gain on sale of property, plant, and equipment in the Consolidated Statement of Operations for the year ended September 30, 2024.

(4) Includes unamortized debt issuance costs of $2.9 and $3.4 at September 30, 2024 and 2023, respectively. The following table summarizes the scheduled maturities of long-term debt for 2025 through 2029: Amount 2025 $ 20.6 2026 404.3 2027 627.8 2028 — 2029 500.0 Primary Financing Facilities $1,000 Revolving Credit Facility, $200 Term Loan, and €185 Term Loan On June 8, 2022, the Company entered into a Fourth Amended and Restated Credit Agreement (such agreement, as amended from time to time as detailed below, the “Prior Credit Agreement”), which governs the multi-currency revolving credit facility (the “Facility”), by and among Hillenbrand and certain of its affiliates, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent. The Prior Credit Agreement increased the maximum principal amount available for borrowing under the Facility to $1,000. The aggregate principal amount available for borrowing under the Prior Credit Agreement may be expanded, subject to the approval of the lenders, by an additional $600. The Prior Credit Agreement extended the maturity date of the Facility to June 8, 2027. The Prior Credit Agreement further provided for a delayed-draw term loan facility in an aggregate principal amount of up to $200. The term loan commitment was subject to ticking fees if not drawn within 60 days of closing. The Prior Credit Agreement fully transitioned interest rate benchmarks from LIBOR-based interest rates to SOFR-based interest rates for U.S. dollar borrowings. Borrowings under the Prior Credit Agreement may bear interest (A) if denominated in US dollars, at the Term SOFR Rate or the Alternate Base Rate (each as defined in the Prior Credit Agreement) at the Company’s option, (B) if denominated in Japanese Yen, Canadian dollars or Euros, at rates based on the rates offered for deposits in the applicable interbank markets for such currencies and (C) if denominated in Pounds Sterling or Swiss Francs, at SONIA and SARON, respectively (each as defined in the Prior Credit Agreement), plus, in each case, margin based on the Company’s leverage ratio, ranging from 0% to 0.525% for borrowings bearing interest at the Alternate Base Rate and from 0.90% to 1.525% for all other borrowings. The $200 Term Loan accrues interest, at the Company’s option, at the Term SOFR Rate or the Alternate Base Rate plus a margin based on the Company’s leverage ratio, ranging from 1.00% to 1.75% for term loans bearing interest at the Term SOFR Rate and 0% to 0.75% for term loans bearing interest at the Alternate Base Rate. In November 2022, the Company drew $200 on the $200 Term Loan. The $200 Term Loan is subject to quarterly amortization payments equal to $2.5 for the first full twelve calendar quarters following the funding date, and quarterly amortization payments equal to $3.8 thereafter until the maturity date. The $200 Term Loan will mature on June 8, 2027. On June 21, 2023, the Company entered into Amendment No. 1 to the Prior Credit Agreement (“Amendment No.1”). Amendment No. 1 includes, among other changes, establishment of a euro-denominated, delayed-draw term loan facility available to the Company’s wholly owned subsidiary, Hillenbrand Switzerland GmbH, in an initial aggregate principal amount of up to €185 (the “€185 Term Loan”) and the inclusion of requirements that would be triggered by a Collateral Springing Event (described below). In August 2023, the Company drew €185.0 on the €185 Term Loan. The €185 Term Loan is subject to quarterly amortization payments equal to €2.3 for the first full eight calendar quarters following the funding date, and €3.5 thereafter until the maturity date. The €185 Term Loan accrues interest at the Adjusted EURIBO Rate (as defined in Amendment No.1) plus a margin based on the Company’s leverage ratio, ranging from 1.00% to 2.25%, and will mature on June 8, 2027. On May 10, 2024, the Company entered into Amendment No. 3 to the Prior Credit Agreement (“Amendment No.3”). Amendment No. 3 provides for a replacement benchmark rate for borrowings in Canadian Dollars, replacing the Canadian Dollar Overnight Rate, which will no longer be published, as defined further in Amendment No. 3. On September 23, 2024, the Company entered into Amendment No. 4 to the Prior Credit Agreement (as amended, the “Amended Credit Agreement”). The Amended Credit Agreement increased the maximum permitted leverage ratio to 4.50x for the quarters ended September 30, 2024 and December 31, 2024, stepping down to 4.25x for the quarter ended March 31, 2025, stepping down to 4.00x for the quarters ended June 30, 2025, September 30, 2025 and December 31, 2025, stepping down to 3.75x for the quarter ended March 31, 2026, and stepping down to 3.50x for the quarter ended June 30, 2026, and thereafter. Except for the amendments applicable during the Adjustment Period (defined below), the Amended Credit Agreement contains substantially the same affirmative and negative covenants and events of default. New deferred financing costs related to the Amended Credit Agreement were $1.0, which along with existing costs of $4.5, are being amortized to interest expense over the remaining term of the Amended Credit Agreement. With respect to the Facility, as of September 30, 2024 and 2023, the Company had outstanding balances of $298.5 and $505.1, respectively. As of September 30, 2024, the Company had $20.3 in outstanding letters of credit issued. Under the Amended Credit Agreement, the Company had $681.2 of available borrowing capacity as of September 30, 2024, of which $599.4 was immediately available based on our most restrictive covenant. The weighted-average interest rate on borrowings under the Facility was 5.76% and 3.05% for the years ended September 30, 2024 and 2023, respectively. The weighted average facility fee was 0.23% and 0.17% for the years ended September 30, 2024 and 2023, respectively. The weighted-average interest rate on the $200 Term Loan was 7.22% and 6.30% for the years ended September 30, 2024 and 2023, respectively. The weighted-average interest rate on the €185 Term Loan was 5.63% and 5.39% for the years ended September 30, 2024 and 2023, respectively. €325 L/G Facility Agreement On June 21, 2022, Hillenbrand and certain of its subsidiaries entered into a Syndicated L/G Facility Agreement (such agreement, as amended from time to time as detailed below, the “Prior L/G Facility Agreement”) with Commerzbank Aktiengesellschaft, as coordinator, mandated lead arranger, and bookrunner, the other financial institutions party thereto as lenders and issuing banks, and Commerzbank Finance & Covered Bond S.A., as agent. The Prior L/G Facility Agreement replaced the Company’s Syndicated L/G Facility Agreement dated March 8, 2018, as amended, and permits Hillenbrand and certain of its subsidiaries (collectively, the “Participants”) to request that one or more of the lenders issue, on the Participants’ behalf, up to an aggregate of €225 in unsecured letters of credit, bank guarantees, or other surety bonds (collectively, the “Guarantees”). The Guarantees carry an annual fee that varies based on the Company’s leverage ratio. The Prior L/G Facility Agreement also provides for a leverage-based commitment fee assessed on the undrawn portion of the facility. On June 22, 2023, the Company entered into an Amendment and Restatement Agreement which amends and restates the Prior L/G Facility Agreement (the “Amended Prior L/G Facility Agreement”). The Amended Prior L/G Facility Agreement includes, among other changes, an increase in the facility from €225 to €325 and the inclusion of requirements that would be triggered by a Collateral Springing Event (described below). On September 23, 2024, the Company, Commerzbank Aktiengesellschaft, as coordinator, mandated lead arranger, and bookrunner, and the other financial institutions party thereto as lenders and issuing banks, amended the terms of the Amended Prior Amended L/G Facility Agreement (“the Amended L/G Facility Agreement”) to increase the maximum permitted leverage ratio to 4.50x for the quarters ended September 30, 2024 and December 31, 2024, stepping down to 4.25x for the quarter ended March 31, 2025, stepping down to 4.00x for the quarters ended June 30, 2025, September 30, 2025 and December 31, 2025, stepping down to 3.75x for the quarter ended March 31, 2026, and to 3.50x for the quarter ended June 30, 2026, and thereafter. Except for the amendments applicable during the Adjustment Period, the Amended L/G Facility Agreement contains substantially the same affirmative and negative covenants and events of default. New deferred financing costs related to the Amended L/G Facility Agreement were $0.2, which along with existing costs of $2.0, are being amortized to interest expense over the remaining term of the Amended L/G Facility Agreement. Guarantees may be issued in euros or certain other agreed-upon currencies. Specified sublimits apply, based on the specific lender and currency. The Amended L/G Facility Agreement also provides for a leverage-based commitment fee assessed on the undrawn portion of the facility. The Amended L/G Facility Agreement matures on June 22, 2027, but can be extended or terminated earlier under certain conditions. The Amended L/G Facility Agreement contains representations, warranties, and covenants that are customary for agreements of this type and contains specified customary events of default. The obligations under the Amended L/G Facility Agreement are guaranteed by Hillenbrand and certain of its domestic subsidiaries named therein. In the normal course of business, the Company provides, primarily to certain customers, bank guarantees and other credit arrangements in support of performance, warranty, advance payment, and other contractual obligations. This form of trade finance is customary in the industry and, as a result, the Company maintains adequate capacity to provide the guarantees. As of September 30, 2024, the Company had credit arrangements totaling $594.3, under which $400.2 was utilized for this purpose. These arrangements included the facilities under the Amended L/G Facility Agreement and other ancillary credit facilities. Collateral Springing Event The Amended Credit Agreement and the Amended L/G Facility Agreement require the Company and certain domestic subsidiaries that are guarantors thereunder to take certain actions if a Collateral Springing Event (as defined in the agreements) occurs before the later of April 1, 2025 or the date that all principal, interest, and other amounts owing in respect of the €185 Term Loan have been paid in full (the “Adjustment Period”). After a Collateral Springing Event, the Company and the guarantors would be required to grant liens on substantially all of their assets (subject to customary exceptions for excluded assets, including an exception for Principal Property (as defined in the Company’s indentures in respect of its senior notes) and for capital stock of entities that own any such Principal Property) in favor of the Administrative Agent and L/G Agent, as applicable, for the benefit of the secured parties. Long Term Notes $500 Senior Unsecured Notes On February 14, 2024, the Company issued $500.0 of senior unsecured notes due February 2029 (the “2024 Notes”). The 2024 Notes were issued at par value and bear interest at a fixed rate of 6.25% per year, payable semi-annually in arrears beginning August 2024. Unamortized deferred financing costs associated with the 2024 Notes of $5.4 are being amortized to interest expense on a straight-line basis (which approximates the effective interest method) over the term of the 2024 Notes. The 2024 Notes are unsecured unsubordinated obligations of the Company and rank equally in right of payment with all other existing and future unsubordinated obligations. Subject to certain limitations, in the event of a change of control repurchase event (as defined in the 2024 Notes), the Company will be required to make an offer to purchase the 2024 Notes at a price equal to 101% of the principal amount of the 2024 Notes, plus any accrued and unpaid interest to, but excluding, the date of repurchase. The Company may redeem the 2024 Notes at any time in whole, or from time to time in part, prior to February 15, 2026, at its option at the “make-whole” redemption price, as described in the Indenture. The Company may also redeem the 2024 Notes at any time in whole, or from time to time in part, on or after February 15 of the relevant year listed, as follows: 2026 at a redemption price of 103.125%; 2027 at a redemption price of 101.5625%; and 2028 and thereafter at a redemption price of 100%. At any time prior to February 15, 2026, the Company may redeem up to 40% of the aggregate principal amount of the 2024 Notes with the proceeds of one or more Equity Offerings (as defined in the Indenture) at a redemption price of 106.25% of the principal amount of the 2024 Notes being redeemed. In each of the above cases, the Company will also pay any accrued and unpaid interest to, but excluding, the applicable redemption date. $350 Senior Unsecured Notes On March 3, 2021, the Company issued $350.0 of senior unsecured notes due March 2031 (the “2021 Notes”). The 2021 Notes were issued at par value and bear interest at a fixed rate of 3.75% per year, payable semi-annually in arrears beginning September 2021. Unamortized deferred financing costs associated with the 2021 Notes of $2.9 are being amortized to interest expense on a straight-line basis (which approximates the effective interest method) over the term of the 2021 Notes. The 2021 Notes are unsecured unsubordinated obligations of the Company and rank equally in right of payment with all other existing and future unsubordinated obligations. Subject to certain limitations, in the event of a change of control repurchase event (as defined in the 2021 Notes), the Company will be required to make an offer to purchase the 2021 Notes at a price equal to 101% of the principal amount of the 2021 Notes, plus any accrued and unpaid interest to, but excluding, the date of repurchase. The Company may redeem the 2021 Notes at any time in whole, or from time to time in part, prior to March 1, 2026, at its option at the “make-whole” redemption price, as described in the Indenture. The Company may also redeem the 2021 Notes at any time in whole, or from time to time in part, on or after March 1 of the relevant year listed, as follows: 2026 at a redemption price of 101.875%; 2027 at a redemption price of 101.25%; 2028 at a redemption price of 100.625%; and 2029 and thereafter at a redemption price of 100%. In each of the above cases, the Company will also pay any accrued and unpaid interest to, but excluding, the applicable redemption date. $400 Senior Unsecured Notes On June 16, 2020, the Company issued $400.0 of senior unsecured notes due June 2025 (the “2020 Notes”). The 2020 Notes were issued at par value and bear interest at a fixed rate of 5.75% per year, payable semi-annually in arrears beginning December 2020. During the year ended September 30, 2024, the 2020 Notes were repaid in full by the Company, using a portion of the net proceeds from the 2024 Notes, and the remaining issuance costs of $1.1 associated with the 2020 Notes were written off to interest expense in the Consolidated Statement of Operations. $375 Senior Unsecured Notes On September 25, 2019, the Company issued $375.0 of senior unsecured notes due September 2026 (“2019 Notes”). The 2019 Notes initially had a fixed coupon rate of 4.5% per year, payable semi-annually in arrears beginning March 2020. The coupon rate on the 2019 Notes is impacted by public bond ratings from Moody’s and S&P Global, as downgrades from either rating agency increases the coupon rate by 0.25% per downgrade level below investment grade. During the third quarter of 2020, Moody’s and S&P Global each downgraded the Company’s senior unsecured credit rating by one level. As such, the original coupon rate of 4.5% on the 2019 Notes increased to 5%, effective September 15, 2020. The 2019 Notes were issued at a discount of $0.6, resulting in an initial carrying value of $374.4. The Company is amortizing the discount to interest expense over the term of the 2019 Notes using the effective interest rate method, resulting in an annual interest rate of 4.53%. Unamortized deferred financing costs associated with the 2019 Notes of $1.2 are being amortized to interest expense on a straight-line basis (which approximates the effective interest method) over the remaining term of the 2019 Notes. The 2019 Notes are unsubordinated obligations of Hillenbrand and rank equally in right of payment with all of the Company’s other existing and future unsubordinated obligations. Subject to certain limitations, in the event of a change of control, the Company will be required to make an offer to purchase the 2019 Notes at a price equal to 101% of the principal amount of the 2019 Notes, plus accrued and unpaid interest, if any, to but excluding the date of repurchase. In addition, the 2019 Notes are redeemable with prior notice at a price equal to par plus accrued interest and a make-whole amount. $100 Series A Unsecured Notes On December 15, 2014, the Company issued $100.0 in 4.6% Series A unsecured notes (“Series A Notes”) pursuant to the Private Shelf Agreement, dated as of December 6, 2012, among the Company, Prudential Investment Management, Inc. (“Prudential”) and each Prudential Affiliate (as defined therein) that became a purchaser thereunder. During the year ended September 30, 2023, the Company repaid in full the Series A Notes using a portion of the net proceeds from the Batesville divestiture and wrote off the remaining issuance costs ($0.1). Covenants related to current Hillenbrand financing agreements Except as described above, the Amended Credit Agreement and the Amended L/G Facility Agreement contain the following financial covenants: a maximum leverage ratio (as described above and defined in the agreements) of 3.50 to 1.00 and minimum ratio of EBITDA (as defined in the agreements) to interest expense of 3.00 to 1.00. The Company may elect to increase the maximum permitted leverage ratio to a ratio of 4.00 to 1.00 following certain acquisitions for four full fiscal quarters (plus the fiscal quarter in which the acquisition takes place). Additionally, the Amended Credit Agreement and the Amended L/G Facility Agreement provide the Company with the ability to sell assets and to incur debt at its international subsidiaries under certain conditions. All obligations of the Company arising under the Amended Credit Agreement, the 2024 Notes, the 2021 Notes, the 2020 Notes, the 2019 Notes, and the Amended L/G Facility Agreement are fully and unconditionally, and jointly and severally, guaranteed by certain of the Company’s domestic subsidiaries. The Amended Credit Agreement and the Amended L/G Facility Agreement each contains certain other customary covenants, representations and warranties and events of default. The indentures governing the 2024 Notes, 2021 Notes, 2020 Notes and 2019 Notes do not limit our ability to incur additional indebtedness. They do, however, contain certain covenants that restrict our ability to incur secured debt and to engage in certain sale and leaseback transactions. The indentures also contain customary events of default . The indentures provide holders of the notes with remedies if the Company fails to perform specific obligations. As of September 30, 2024, the Company was in compliance with all covenants and there were no events of default.

Retirement Benefits [Abstract]
Retirement Benefits	Retirement Benefits Defined Benefit Retirement Plans — Certain of the Company’s employees participate in one of nine defined benefit retirement programs, including the defined benefit retirement plans of certain of the Company’s foreign subsidiaries, and the supplemental executive defined benefit retirement plan. The Company funds the retirement plan trusts in compliance with the Employment Retirement Income Security Act (ERISA) or local funding requirements and as necessary to provide for current service and for any unfunded projected future benefit obligations over a reasonable period. The benefits for these plans are based primarily on years of service and the employee’s level of compensation during specific periods of employment. All defined benefit retirement plans have a September 30 measurement date. Effect on the Consolidated Statements of Operations — The components of net pension costs (benefit) under defined benefit retirement plans were: U.S. Pension Benefits Non-U.S. Pension Benefits 2024 2023 2022 2024 2023 2022 Service cost (1) $ — $ — $ — $ 1.8 $ 1.5 $ 1.8 Interest cost 7.2 11.1 6.2 4.5 4.2 0.8 Expected return on plan assets (8.3) (13.6) (10.8) (1.5) (1.5) (0.9) Amortization of unrecognized prior service cost, net — — — 0.1 0.1 0.1 Amortization of actuarial loss (gain) 0.3 0.3 1.5 (0.7) (0.8) 1.8 Settlement expense (benefit) 35.2 — — 0.5 (0.3) 0.1 Other one-time expense — — — — — 0.3 Net pension costs (benefit) (2) $ 34.4 $ (2.2) $ (3.1) $ 4.7 $ 3.2 $ 4.0 (1) Service cost for U.S. Pension Benefits includes $0.0, $0.1 and $0.5 included within discontinued operations for the years ended September 30, 2024, 2023 and 2022, respectively. (2) The components of net pension costs (benefit) are recorded within operating expenses on the Consolidated Statements of Operations. The Company uses a full yield curve approach in the estimation of the service and interest cost components of our defined benefit retirement plans. Under this approach, the Company applies discounting using individual spot rates from a yield curve composed of the rates of return on several hundred high-quality, fixed income corporate bonds available at the measurement date. These spot rates align to each of the projected benefit obligations and service cost cash flows. The service cost component relates to the active participants in the plan, so the relevant cash flows on which to apply the yield curve are considerably longer in duration on average than the total projected benefit obligation cash flows, which also include benefit payments to retirees. Interest cost is computed by multiplying each spot rate by the corresponding discounted projected benefit obligation cash flows. The full yield curve approach reduces any actuarial gains and losses based upon interest rate expectations (e.g. built-in gains in interest cost in an upward sloping yield curve scenario), or gains and losses merely resulting from the timing and magnitude of cash outflows associated with the Company’s benefit obligations. The Company uses the full yield curve approach to improve the correlation between projected benefit cash flows and the corresponding yield curve spot rates and to provide a more precise measurement of service and interest rate costs. During 2019, the Company completed all negotiations to transition all employees at U.S. facilities from a defined benefit-based model to a defined contribution structure over three-year sunset periods, the latest of which ended January 1, 2023. These changes caused remeasurements for the U.S. defined benefit pension plan (the “Plan”) for the affected populations as they were implemented. The remeasurements did not cause material changes, as the assumptions did not materially differ from the assumptions prior to the remeasurements. On July 18, 2023, we announced an offer to provide former employees who are participants in the Plan the opportunity to elect a lump sum distribution of their earned Plan benefits. The Plan’s fiduciaries made lump sum payments to electing eligible participants in December 2023, funded by the existing assets in the Plan. In April 2024, the remaining assets of the Plan were used to purchase annuities to support the remaining obligation, resulting in the termination and liquidation of the Plan. During the year ended September 30, 2024, the Company recorded non-cash settlement pre-tax charges of $35.2, related to the termination and liquidation of the Plan, as well as to the lump sum payments made in December 2023. Obligations and Funded Status — The change in benefit obligation and funded status of the Company’s defined benefit retirement plans were: U.S. Pension Benefits Non-U.S. Pension Benefits 2024 2023 2024 2023 Change in benefit obligation: Projected benefit obligation at beginning of year $ 213.6 $ 226.8 $ 131.5 $ 118.1 Projected benefit obligation attributable to acquisitions — — — 2.7 Service cost — — 1.8 1.5 Interest cost 7.2 11.1 4.5 4.2 Actuarial loss (gain) 1.5 (9.1) 12.5 1.5 Benefits paid (54.3) (15.3) (5.5) (3.5) Settlements — — (5.0) (3.7) Transfer of participants benefit obligation (150.0) — — — Employee contributions — — 1.4 1.3 Other events — 0.1 — — Effect of exchange rates on projected benefit obligation — — 9.8 9.4 Projected benefit obligation at end of year 18.0 213.6 151.0 131.5 Change in plan assets: Fair value of plan assets at beginning of year 219.2 225.4 49.0 41.5 Actual (loss) return on plan assets (16.6) 7.1 3.2 1.7 Employee and employer contributions 1.7 2.0 10.3 9.8 Benefits paid (54.3) (15.3) (5.5) (3.5) Settlements — — (5.0) (3.7) Annuity premium for transferred participants (150.0) — — — Effect of exchange rates on plan assets — — 4.6 3.2 Fair value of plan assets at end of year — 219.2 56.6 49.0 Funded status: Plan assets (less) more than benefit obligations $ (18.0) $ 5.6 $ (94.4) $ (82.5) Amounts recorded in the Consolidated Balance Sheets: Prepaid pension costs, non-current $ — $ 25.3 $ 3.1 $ 4.7 Accrued pension costs, current portion (1.7) (1.9) (7.0) (6.7) Accrued pension costs, long-term portion (16.3) (17.8) (90.5) (80.5) Plan assets (less) more than benefit obligations $ (18.0) $ 5.6 $ (94.4) $ (82.5) Net actuarial losses ($21.1) and prior service costs ($0.1), less an aggregate tax effect ($5.0), are included as components of accumulated other comprehensive loss at September 30, 2024. Net actuarial losses ($46.2) and prior service costs ($0.1), less an aggregate tax effect ($11.7), are included as components of accumulated other comprehensive loss at September 30, 2023. The amount that will be amortized from accumulated other comprehensive loss into net pension costs (benefit) in 2025 is expected to be $0.5. Accumulated Benefit Obligation — The accumulated benefit obligation for all defined benefit retirement plans was $169.0 and $345.0 at September 30, 2024 and 2023, respectively. Selected information for plans with accumulated benefit obligations in excess of plan assets was: U.S. Pension Benefits Non-U.S. Pension Benefits 2024 2023 2024 2023 Projected benefit obligation $ 18.0 $ 19.7 $ 97.8 $ 87.5 Accumulated benefit obligation 18.0 19.7 97.8 87.5 Fair value of plan assets — — 0.3 0.3 The weighted-average assumptions used in accounting for defined benefit retirement plans were: U.S. Pension Benefits Non-U.S. Pension Benefits 2024 2023 2022 2024 2023 2022 Discount rate for obligation, end of year 4.6 % 5.7 % 5.3 % 2.7 % 3.5 % 3.3 % Discount rate for costs (benefit), during the year 5.4 % 5.4 % 3.0 % 3.5 % 3.9 % 1.1 % Expected rate of return on plan assets N/A 5.2 % 5.2 % 2.9 % 3.1 % 1.9 % Rate of compensation increase N/A N/A 3.0 % 2.0 % 2.0 % 2.0 % The discount rates are evaluated annually based on current market conditions. In setting these rates, the Company utilizes long-term bond indices and yield curves as a preliminary indication of interest rate movements, then makes adjustments to the indices to reflect differences in the terms of the bonds covered under the indices in comparison to the projected outflow of pension obligations. The overall expected long-term rate of return is based on historical and expected future returns, which are inflation-adjusted and weighted for the expected return for each component of the investment portfolio. The rate of assumed compensation increase is also based on the Company’s specific historical trends of past wage adjustments in recent years. U.S. Pension Plan Assets — As discussed above, the Plan was terminated and liquidated during 2024. Prior to the termination of the Plan, the Company had employed a 100% liability-hedging portfolio of investments in order to reduce the volatility associated with equity investments. Pension plan assets were invested by the plans’ fiduciaries, which directed investments according to specific policies. Those policies subjected investments to the following restrictions in the Company’s domestic plan: short-term securities had to be rated A1/P1, liability-hedging fixed income securities had an average quality credit rating of investment grade, and investments in equities in any one company may not exceed 10% of the equity portfolio. Non-U.S. Pension Plan Assets — Long-term strategic investment objectives utilize a diversified mix of suitable assets of appropriate liquidity to generate income and capital growth that, together with contributions from participants, the Company believes will meet the cost of the current and future benefits that the plan provides. Long-term strategic investment objectives also seek to limit the risk of the assets failing to meet the liabilities over the long term. None of Hillenbrand’s common stock was directly owned by the defined benefit retirement plan trusts at September 30, 2024 or 2023. The tables below provide the fair value of the Company’s pension plan assets by asset category at September 30, 2024 and 2023. The accounting guidance on fair value measurements specifies a fair value hierarchy based upon the observability of inputs used in valuation techniques (Level 1, 2, and 3). See Note 14 for definitions. Fair values are determined as follows: • Cash equivalents are stated at the carrying amount, which approximates fair value, or at the fund’s net asset value. • Equity securities are stated at the last reported sales price on the day of valuation. • Fixed income securities, including government and corporate bonds, are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources, primarily matrix pricing, with reasonable levels of price transparency. Matrix pricing, primarily used for corporate bonds, is based on quoted prices for securities with similar coupons, ratings, and maturities, rather than on specific bids and offers for the specific security. • Government index funds are stated at the closing price reported in the active market in which the fund is traded. • Corporate bond funds and equity mutual funds are stated at the closing price in the active markets in which the underlying securities of the funds are traded. • Real estate is stated based on a discounted cash flow approach, which includes future rental receipts, expenses, and residual values as the highest and best use of the real estate from a market participant view as rental property. U.S. Pension Plans Prior to the termination of the Plan, the pension plan assets of the Plan consisted of cash equivalents as well as certain investments (common collective trusts) that were measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The underlying investments of the common collective trusts were generally composed of marketable debt and equity securities. The underlying investments were subject to various risks including interest rate, market and credit risks. Because the common collective trusts were not readily marketable, the estimated carrying values were subject to uncertainty and, therefore, could have differed from the value that would have been used had a public market existed. There are no liquidity restrictions with respect to the common collective trusts after appropriate sale notification is provided. Accordingly, these assets were not required to be classified and reported under the fair value hierarchy. At September 30, 2024 and 2023, the fair values of these investments were $0.0 and $144.5, respectively. At September 30, 2024, and 2023, the fair value of cash equivalents were $0.0 and $74.7, respectively, and are categorized in Level 1 in the fair value hierarchy.

The Company expects to make estimated contributions of $11.8 in 2025 to the defined benefit retirement plans. Estimated Future Benefit Payments — The following represents estimated future benefit payments, including expected future service, which are expected to be paid from plan assets or Company contributions as necessary: U.S. Pension Plans Non-U.S. Pension Plans 2025 $ 1.7 $ 9.8 2026 1.7 10.0 2027 1.7 10.2 2028 1.6 9.7 2029 1.6 9.6 2030-2034 7.1 45.1 Defined Contribution Plans — The Company sponsors a number of defined contribution plans.

The majority of the foreign net operating loss and interest carryforwards have unlimited carryforward periods. Portions of the net operating loss carryforwards with expiration periods will begin to expire in 2025. Deferred tax assets as of September 30, 2024 and 2023, were reduced by a valuation allowance of $21.2 and $34.1, respectively, relating to foreign net operating loss carryforwards and foreign tax credit carryforwards. At September 30, 2024 and 2023, the Company had $16.5 and $72.8, respectively, of current income tax payable included in other current liabilities on the Consolidated Balance Sheets. As of September 30, 2024 and 2023, the Company also had a transition tax liability of $6.2 and $11.2 included within other long-term liabilities on the Consolidated Balance Sheets. The Company establishes a valuation allowance for deferred tax assets when it is determined that the amount of expected future taxable income is not likely to support the use of the deduction or credit. As of September 30, 2024 and 2023, respectively, $11.5 and $8.6 of deferred tax liability on unremitted earnings of foreign subsidiaries was recognized, representing the assumed tax on the future distribution and tax withholdings on the distribution of such earnings among certain of the Company’s foreign subsidiaries. Deferred tax liabilities were not recorded for any additional basis differences inherent in the Company’s foreign subsidiaries (i.e., basis differences in excess of those subject to the Transition Tax) as these amounts continue to be permanently reinvested outside of the U.S. If these amounts were not considered permanently reinvested, deferred tax liabilities would be recorded for any additional income taxes, distribution taxes, and withholding taxes payable in various countries. A determination of the unrecognized deferred tax liabilities on the permanently reinvested basis differences at September 30, 2024 is not practicable. A reconciliation of the unrecognized tax benefits is as follows: September 30, 2024 2023 2022 Balance at beginning of year $ 38.9 $ 33.9 $ 40.5 Additions for tax positions related to the current year 31.6 0.7 — Additions for tax positions of prior years 2.5 0.6 1.0 Reductions for tax positions of prior years (0.8) (2.9) (6.9) Settlements (0.1) (1.7) (0.7) Balance attributable to acquisitions 5.8 8.3 — Balance at end of year $ 77.9 $ 38.9 $ 33.9 The gross unrecognized tax benefit included $77.9 and $38.9 at September 30, 2024 and 2023, respectively, which, if recognized, would impact the effective tax rate in future periods. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. During 2024 and 2023, the Company recognized $2.6 and $0.9, respectively, in additional interest and penalties. Excluded from the reconciliation were $7.5 and $4.9 of accrued interest and penalties at September 30, 2024 and 2023, respectively. The Company operates in multiple income tax jurisdictions both inside and outside the U.S. and are currently under examination in various federal, state, and foreign jurisdictions. There are ongoing audits in India, Canada, Germany, and the Czech Republic specifically which could prove to be significant for the Company. In addition, there are other ongoing audits in various stages of completion in several state and foreign jurisdictions. It is possible that the liability associated with the unrecognized tax benefits will increase or decrease within the next 12 months. These changes may be the result of ongoing audits or the expiration of statutes of limitations and could range up to $0.5 based on current estimates. Audit outcomes and the timing of audit settlements are subject to significant uncertainty. Although the Company believes that adequate provision has been made for such issues, it is possible that their ultimate resolution could affect earnings. Conversely, if these issues are resolved favorably in the future, the related provision would be reduced and yield a positive impact on earnings. The Company does not expect that the outcome of these audits will significantly impact the Consolidated Financial Statements.

Compensation Related Costs [Abstract]
Share-Based Compensation	Share-Based Compensation The Company has share-based compensation plans under which 15,385,436 shares are registered. As of September 30, 2024, 2,174,230 shares were outstanding under these plans and 10,525,888 shares had been issued, leaving 2,637,050 shares available for future issuance. Our primary plan, the Hillenbrand, Inc. Stock Incentive Plan, provides for long-term performance compensation for management and members of the Board of Directors. Under the Stock Incentive Plan, a variety of discretionary awards for employees and non-employee directors are authorized, including incentive or non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, and bonus stock. These programs are administered by the Board of Directors and its Compensation and Management Development Committee. Year Ended September 30, 2024 2023 2022 Stock-based compensation cost $ 20.3 $ 22.2 $ 21.3 Less impact of income tax 4.7 5.1 4.9 Stock-based compensation cost, net of tax $ 15.6 $ 17.1 $ 16.4 The Company realized current tax benefits o f $3.2 , $6.4 and $5.8 from the exercise of stock options and the payment of stock awards during the years ended September 30, 2024, 2023 and 2022, respectively. Stock Options — No stock options were issued during the years ended September 30, 2024, 2023 and 2022. A summary of outstanding stock option awards as of September 30, 2024 and changes during the year is presented below: Number Weighted-Average Outstanding at September 30, 2022 1,251,722 $ 36.47 Granted — — Exercised (618,414) 34.39 Forfeited — — Expired/cancelled (5,699) 31.14 Outstanding at September 30, 2023 627,609 38.56 Granted — — Exercised (68,140) 35.85 Forfeited — — Expired/cancelled (5,578) 37.15 Outstanding at September 30, 2024 553,891 $ 38.91 Exercisable at September 30, 2024 553,891 $ 38.91 As of September 30, 2024, there was no unrecognized stock-based compensation associated with unvested stock options. As of September 30, 2024, the average remaining life of the outstanding and exercisable stock options was 3.4 years with an aggregate intrinsic value of $0.0. The total intrinsic value of options exercised by employees and directors during the years ended September 30, 2024, 2023, and 2022 was $0.7, $9.2, and $9.6, respectively. The grant-date fair value of options that vested during the years ended September 30, 2024, 2023, and 2022 was $0.0, $2.2, and $11.5, respectively. Time-Based Stock Awards and Performance-Based Stock Awards — These awards are consistent with the Company’s compensation program’s guiding principles and are designed to (i) align management’s interests with those of shareholders, (ii) motivate and provide incentive to achieve superior results, (iii) maintain a significant portion of at-risk incentive compensation, (iv) delineate clear accountabilities, and (v) ensure competitive compensation. The Company believes that the blend of compensation components provides the Company’s management with the appropriate incentives to create long-term value for shareholders while taking thoughtful and prudent risks to grow the value of the Company. The Company’s stock plan enables us to grant several types of restricted stock unit awards including time-based, performance-based contingent on the creation of shareholder value (“SV”), and performance-based based on a relative total shareholder return formula (“TSR”). The Company’s time-based stock awards provide an unconditional delivery of shares after a specified period of service. The Company records expense associated with time-based awards on a straight-line basis over the vesting period, net of estimated forfeitures. The vesting of the SV awards granted in fiscal 2024 is contingent upon the creation of shareholder value as measured by the cumulative cash returns and final period net operating profit after tax compared to the established hurdle rate over a three-year period and a corresponding service requirement. The hurdle rate is a reflection of the weighted-average cost of capital and targeted capital structure. The number of shares awarded is based upon the fair value of the Company’s common stock at the date of grant adjusted for the attainment level at the end of the period. Based on the extent to which the performance criteria are achieved, it is possible for none of the awards to vest or for a range up to the maximum (200 percent) to vest. The Company records expense associated with the awards on a straight-line basis over the vesting period based upon an estimate of projected performance. The actual performance of the Company is evaluated quarterly, and the expense is adjusted according to the new projections. As a result, depending on the degree to which performance criteria are achieved or projections change, expenses related to the SV awards may become more volatile as the Company approaches the final performance measurement date at the end of the three-year period. The vesting of TSR awards granted in fiscal 2024 will be determined by comparing the Company’s total shareholder return during a three-year period to the respective total shareholder returns of members of the Standard & Poor’s 400 Mid Cap Industrials index (the “Index Companies”). Based on the Company’s relative ranking within the Index Companies, performance below the 25th percentile earns a zero payout, a 25 percent minimum payout for achievement at the 25th percentile, 100 percent payout at 50th percentile achievement, and 200 percent payout at 75th percentile achievement and above. Compensation expense for the TSR awards is recognized over the vesting period regardless of whether the market conditions are expected to be achieved. The Company estimates the fair value of TSR awards using a Monte-Carlo simulation model which included the following key assumptions: Year Ended Year Ended September 30, 2024 2023 2022 Expected term (years) 2.83 2.83 2.83 Risk-free interest rate 4.28 % 3.96 % 0.86 % Share price volatility 32.40 % 44.70 % 43.90 % Expected dividend yield — % — % — % Actual dividend yield 1.95 % 1.97 % 1.91 % A summary of the non-vested stock awards, including dividends, as of September 30, 2024 (representing the maximum number of shares that could be vested) and changes during the year is presented below: Number of Shares Weighted-Average Time-Based Stock Awards Non-vested time-based stock awards at September 30, 2022 660,460 $ 42.50 Granted 268,503 50.54 Vested (358,592) 41.36 Forfeited (71,635) 47.62 Non-vested time-based stock awards at September 30, 2023 498,736 46.91 Granted 360,823 39.76 Vested (260,712) 45.51 Forfeited (52,159) 44.51 Non-vested time-based stock awards at September 30, 2024 546,688 $ 43.09 Number of Shares Weighted-Average Performance-Based Stock Awards Non-vested performance-based stock awards at September 30, 2022 538,352 $ 47.69 Granted 368,419 67.04 Vested (187,894) 43.15 Forfeited (136,401) 54.78 Non-vested performance-based stock awards at September 30, 2023 582,476 59.90 Granted 482,914 42.18 Vested (48,268) 46.18 Forfeited (259,062) 53.90 Non-vested performance-based stock awards at September 30, 2024 758,060 $ 51.54 The total vest date fair value of shares held by Hillenbrand employees and directors which vested during the years ended September 30, 2024, 2023, and 2022 was $15.6, $28.0, and $23.0 (including dividends), respectively. As of September 30, 2024, $12.7 and $8.3 of unrecognized stock-based compensation was associated with the Company’s unvested time-based and performance-based (including SV and TSR) stock awards, respectively. The unrecognized amount of compensation related to the SV awards is based upon projected performance to date. The unrecognized compensation cost of the time-based and performance-based awards is expected to be recognized over a weighted-average period of 1.9 and 1.6 years and includes a reduction for an estimate of potential forfeitures. As of September 30, 2024, the outstanding time-based stock awards and performance-based stock awards had an aggregate fair value of $15.2 and $14.4, respectively. Dividends payable in stock accrue on both time-based and SV awards during the performance period and are subject to the same terms as the original grants. Dividends do not accrue on TSR awards during the performance period. As of September 30, 2024, a total of 37,895 shares had accumulated on unvested stock awards due to dividend reinvestments and were included in the tables above. The aggregate fair value of these shares at September 30, 2024 was $1.1. Vested Deferred Stock — Certain stock-based compensation programs allow or require deferred delivery of shares after vesting. As of September 30, 2024, there were 315,591 fully vested deferred shares, which were excluded from the tables above. The aggregate fair value of these shares at September 30, 2024 was $8.8.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation From time to time, Hillenbrand is involved in claims, lawsuits, and government proceedings relating to its operations, including environmental, antitrust, patent infringement, business practices, commercial transactions, product and general liability, workers’ compensation, auto liability, employment-related, and other matters. The ultimate outcome of any claims, lawsuits, and proceedings cannot be predicted with certainty. An estimated loss from these contingencies is recognized when the Company believes it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated; however, it is difficult to measure the actual loss that might be incurred related to these matters. If a loss is not considered probable or cannot be reasonably estimated, the Company is required to make a disclosure if there is at least a reasonable possibility that a significant loss may have been incurred. Legal fees associated with claims and lawsuits are generally expensed as incurred. Claims covered by insurance have in most instances deductibles and self-funded retentions up to $0.5 per occurrence or per claim, depending upon the type of coverage and policy period. For auto, workers compensation, and general liability claims in the U.S., outside insurance companies and third-party claims administrators generally assist in establishing individual claim reserves. An independent outside actuary often provides estimates of ultimate projected losses, including incurred but not reported claims, which are used to establish reserves for losses. For all other types of claims, reserves are established when payment is considered probable and are based upon advice from internal and external counsel and historical settlement information for such claims. The recorded amounts represent the best estimate of the costs the Company will incur in relation to such exposures, but it is possible that actual costs will differ from those estimates. At September 30, 2024 and 2023, the Company had $11.2 and $5.1, respectively, included in other current liabilities on the Consolidated Balance Sheets, related to a discrete commercial dispute stemming from a contract entered into with a Molding Technology Solutions’ customer prior to the Company’s acquisition of the Molding Technology Solutions reportable operating segment.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The authoritative guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are from sources independent of the Company. Unobservable inputs reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is broken down into three levels: Level 1: Inputs are quoted prices in active markets for identical assets or liabilities. Level 2: Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3: Inputs are unobservable for the asset or liability. See the section below titled “Valuation Techniques” for further discussion of how Hillenbrand determines fair value for investments. Carrying Value at September 30, Fair Value at September 30, 2024 Using Inputs Considered as: Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $ 199.3 $ 199.3 $ — $ — DPP receivables 6.7 — 6.7 — Restricted cash 1.1 1.1 — — Restricted cash for benefit plan contributions 27.5 27.5 — — Investments in rabbi trust 4.8 4.8 — — Derivative instruments 19.0 — 19.0 — Liabilities: Revolving Credit Facility 298.5 — 298.5 — $200 term loan 182.5 — 182.5 — €185 term loan 196.5 — 196.5 — $350 senior unsecured notes 350.0 312.9 — — $375 senior unsecured notes 374.8 373.7 — — $500 senior unsecured notes 500.0 509.8 — — Derivative instruments 40.5 — 40.5 — Contingent consideration 14.6 — — 14.6 Carrying Value at September 30, Fair Value at September 30, 2023 Using Inputs Considered as: Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $ 242.9 $ 242.9 $ — $ — Restricted cash 7.3 7.3 — — Investments in rabbi trust 3.3 3.3 — — Derivative instruments 1.5 — 1.5 — Liabilities: Revolving Credit Facility 505.1 — 505.1 — $200 term loan 192.5 — 192.5 — €185 term loan 195.0 — 195.0 — $350 senior unsecured notes 350.0 281.6 — — $400 senior unsecured notes 400.0 395.1 — — $375 senior unsecured notes 374.7 355.0 — — Derivative instruments 1.7 — 1.7 — Valuation Techniques • Cash and cash equivalents, restricted cash, restricted cash for benefit plan contributions, and investments in rabbi trust are classified within Level 1 of the fair value hierarchy. Financial instruments classified as Level 1 are based on quoted market prices in active markets. The types of financial instruments the Company classifies within Level 1 include most bank deposits, money market securities, and publicly traded mutual funds. The Company does not adjust the quoted market price for such financial instruments. • The DPP receivables fair value is based on a discounted cash flow analysis (estimated amount expected to be received) using historical experience and inputs from similar programs, which include the estimated timing of payments and the credit quality of the underlying creditor. Significant changes in any of the inputs in isolation would not result in a materially different fair value estimate. Based on the short-term nature of the DPP receivables, typically 90 -120 days, they are classified as a level 2 measurement. • The Company estimates the fair value of derivative instruments using industry accepted models. The significant Level 2 inputs used in the valuation of derivatives include spot rates, forward rates, and volatility. These inputs were obtained from pricing services, broker quotes, and other sources. • The fair values of the $350 senior unsecured notes, $400 senior unsecured notes, $375 senior unsecured notes, and $500 senior unsecured notes were based on quoted prices in active markets and are classified within Level 1 of the fair value hierarchy. • The fair value of the amounts outstanding under the Facility, $200 term loan, and €185 term loan approximate carrying value, as the Company believes their variable interest rate terms correspond to current market terms, and therefore, are classified within Level 2 of the fair value hierarchy. • The contingent consideration of $14.6 reflects the estimated fair value of contingent future cash payments to the previous owners of FPM for research and development tax credits that were generated by FPM prior to the acquisition date. The Company estimated the fair value of the contingent consideration based on the technical merits of the research and development tax credits using an internally developed analysis. The key inputs to this calculation include the nature of the research and development activities, personnel involved in the research and development activities, the level of research and development spend prior to acquisition by the Company, and interpretation of applicable tax law. The value of these credits is subject to audit by the tax authorities and to the closing of the statute of limitations for the year in which the tax credits are fully utilized, the timing of which is not able to be determined at this time, but we expect to extend several years. There have been no changes in the estimated fair value of the initial calculation of the contingent consideration during the year ended September 30, 2024. The inputs for the liability are unobservable, and therefore, are classified within Level 3 of the fair value hierarchy.

Segment and Geographical Information	Segment and Geographical Information As previously described, on February 1, 2023, the Company completed the divestiture of Batesville. The operating results and cash flows for Batesville have been classified as discontinued operations within the Consolidated Financial Statements for all periods presented. Hillenbrand is now composed of two reportable operating segments: Advanced Process Solutions and Molding Technology Solutions. The Company’s reportable operating segments maintain separate financial information for which results of operations are evaluated on a regular basis by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company records the direct costs of business operations to the reportable operating segments, including stock-based compensation, asset impairments, restructuring activities, and business acquisition costs. Corporate provides management and administrative services to each reportable operating segment. These services include treasury management, human resources, legal, business development, and other public company support functions such as internal audit, investor relations, financial reporting, and tax compliance. With limited exception for certain professional services and back-office and technology costs, the Company does not allocate these types of corporate expenses to the reportable operating segments.

The Company expects that substantially all of the initial costs to complete the Program, which are primarily severance costs, will result in future cash expenditures, and we anticipate the majority of these cash expenditures to be paid in the next twelve months. The restructuring charges within the Advanced Process Solutions reportable operating segment during the years ended September 30, 2024, 2023, and 2022 are related primarily to severance costs. The restructuring charges within the Molding Technology Solutions reportable operating segment and Corporate during the years ended September 30, 2023 and 2022 were primarily related to severance costs associated with productivity initiatives within the Molding Technology Solutions reportable operating segment. At September 30, 2024, $10.6 of restructuring costs were accrued and are expected to be paid over the next twelve months.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 30, 2024
Basis of presentation	Basis of presentation — The accompanying Consolidated Financial Statements include the accounts of Hillenbrand and its subsidiaries, as well as three subsidiaries where the Company’s ownership percentage is less than 100%. The portion of the businesses that are not owned by the Company is presented as noncontrolling interests within shareholders’ equity in the Consolidated Balance Sheets. Income attributable to the noncontrolling interests is separately reported within the Consolidated Statements of Operations. All significant intercompany accounts and transactions have been eliminated. Certain prior period balances have been reclassified to conform to the current presentation.
Use of estimates	Use of estimates — The Company prepared the Consolidated Financial Statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”). GAAP requires management 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 reporting period. The Company’s results are affected by economic, political, legislative, regulatory, and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies, and changes in the prices of raw materials, can have a significant effect on operations. These factors and other events may cause actual results to differ from management’s estimates.
Foreign currency translation	Foreign currency translation — The financial statements of the Company’s foreign subsidiaries are translated into U.S. dollars using period-end exchange rates for assets and liabilities and average exchange rates for operating results. Unrealized translation gains and losses are included in accumulated other comprehensive loss in shareholders’ equity in the Consolidated Balance Sheets. When a transaction is denominated in a currency other than the subsidiary’s functional currency, the Company recognizes a transaction gain or loss in operating expenses, net within the Consolidated Statements of Operations when the transaction is settled.
Cash and cash equivalents	Cash and cash equivalents and restricted cash include short-term investments with original maturities of three months or less. The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents and restricted cash are valued at cost, which approximates their fair value.
Trade receivables	Trade receivables are recorded at the invoiced amount and generally do not bear interest, unless they become past due. The allowance for credit losses is a best estimate of the amount of probable credit losses and collection risk in the existing trade receivables portfolio. Account balances are charged against the allowance when the Company believes it is probable the trade receivables will not be recovered. The Company generally holds trade receivables until they are collected. At September 30, 2024 and 2023, the Company had an allowance for credit losses against trade receivables of $13.6 and $10.1, respectively.
Inventories	Inventories are generally valued at the lower of cost or net realizable value, unless the inventories are acquired in a business combination, at which time it is recorded at fair value. Costs of inventories have been determined principally by the first-in, first-out (“FIFO”) and average cost methods. Inventories are comprised of the following amounts at:
Property, plant, and equipment	Property, plant, and equipment are carried at cost less accumulated depreciation, unless the property, plant and equipment is acquired in a business combination, at which time is recorded at fair value. Depreciation is computed using principally the straight-line method based on estimated useful lives of three three
Leases	Leases — The Company’s lease portfolio is comprised of operating leases primarily for manufacturing facilities, offices, vehicles, and certain equipment. At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on whether the contract conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. Leases are classified as operating or finance leases at the commencement date of the lease. Operating leases are recorded within operating lease right-of-use assets, other current liabilities, and operating lease liabilities in the Consolidated Balance Sheets. The Company’s finance leases were insignificant as of September 30, 2024 and 2023. Leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets. The Company elected an accounting policy to combine lease and non-lease components for all leases. Operating lease right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the implicit rate is generally not readily determinable for most leases, the Company uses an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The incremental borrowing rate reflects the estimated rate of interest that the Company would pay to borrow on a collateralized basis over a similar term in a similar economic environment. Lease expense for operating leases is recognized on a straight-line basis over the lease term.
Goodwill	Goodwill is not amortized, but is tested for impairment at least annually, or on an interim basis upon the occurrence of triggering events or substantive changes in circumstances. Goodwill has been assigned to reporting units. The Company assesses the carrying value of goodwill annually, or more often if events or changes in circumstances indicate there may be impairment. Impairment testing is performed at a reporting unit level. The following table summarizes the changes in the Company’s goodwill, by reportable operating segment, for the years ended September 30, 2024 and 2023: Advanced Process Solutions Molding Technology Solutions Total Balance September 30, 2022 $ 516.0 $ 635.1 $ 1,151.1 Acquisitions (1) 859.4 — 859.4 Acquisition measurement period adjustments (38.9) — (38.9) Foreign currency adjustments 58.4 (1.9) 56.5 Balance September 30, 2023 1,394.9 633.2 2,028.1 Impairment charges — (238.0) (238.0) Acquisition measurement period adjustments (1.3) — (1.3) Foreign currency adjustments 36.6 10.3 46.9 Balance September 30, 2024 $ 1,430.2 $ 405.5 $ 1,835.7 (1) Goodwill associated with the acquisitions of LINXIS Group SAS (“Linxis”), the Peerless Food Equipment business (“Peerless”), and the Schenck Process Food and Performance Materials (“FPM”) business Testing for impairment of goodwill and indefinite-lived intangible assets must be performed annually, or on an interim basis upon the occurrence of triggering events or substantive changes in circumstances that indicate that the fair value of the indefinite-lived intangible asset or reporting unit may have decreased below the carrying value. The Company’s annual goodwill and indefinite-lived intangible asset assessment is performed on July 1 at the indefinite-lived intangible asset and reporting unit level, which consists of determining each indefinite-lived intangible asset or reporting unit’s current fair value compared to its current carrying value. Annual impairment assessment The Company performed its annual July 1 goodwill and indefinite-lived intangible asset impairment assessments for all reporting units. For all reporting units, the fair value was determined to exceed the carrying value, resulting in no impairment to goodwill as part of this assessment for the years ended September 30, 2024, 2023, and 2022. For purposes of the quantitative goodwill impairment assessment, weighting is equally attributed to both the market and income approaches in arriving at the fair value of the reporting units. The key assumptions for the market and income approaches we use to determine fair value of our reporting units are updated at least annually. Those assumptions and estimates include macroeconomic conditions, competitive activities, cost containment activities, achievement of synergy initiatives, market data and market multiples, discount rates, and terminal growth rates, as well as future levels of net revenue growth and EBITDA margins, which are based upon the Company’s strategic plan. The strategic plan is updated as part of its annual planning process and is reviewed and approved by management and the Board of Directors. The strategic plan may be revised as necessary during a fiscal year, based on changes in market conditions or other changes in the reporting units. The most significant assumptions used in the determination of the estimated fair value of the indefinite-lived intangible assets and reporting units are the net revenue and EBITDA growth rates (including terminal growth rates) and the discount rate. The terminal growth rate represents the rate at which the reporting unit is expected to grow beyond the shorter-term business planning period. The terminal growth rate utilized in the Company’s fair value estimate is consistent with the reporting unit operating plans and approximates expected long-term category market growth rates and inflation. The discount rate, which is consistent with a weighted-average cost of capital that is likely to be expected by a market participant, is based upon industry required rates of return, including consideration of both debt and equity components of the capital structure. The discount rates may be impacted by adverse changes in the macroeconomic environment, volatility in the equity and debt markets, or other factors. Determining the fair value of a reporting unit requires the Company to make significant judgments, estimates, and assumptions. Although there are always changes in assumptions to reflect changing business and market conditions, our overall valuation methodology and the types of assumptions we use have remained consistent and reasonable. However, future changes in the judgments, assumptions, and estimates that are used in the impairment assessment for goodwill, including discount rates and future cash flow projections, could result in significantly different estimates of fair values, resulting in future impairment charges related to recorded goodwill balances. Interim impairment assessment In connection with the preparation of the Consolidated Financial Statements for the third quarter of 2024, an interim impairment assessment was performed for select indefinite-lived intangible assets, specifically trade names, and select reporting units within the Molding Technology Solutions reportable operating segment as a result of certain triggering events and changes in circumstances discussed in detail below. Additionally, based on macroeconomic factors discussed below, and a decline in the Company’s common stock price during the third quarter of 2024, the Company performed a qualitative review for all of the Company’s other indefinite-lived intangible assets and reporting units and determined that those indefinite-lived intangible assets and reporting units did not require an interim impairment assessment, as it was more likely than not that the current fair value of those indefinite-lived intangible assets and reporting units exceeded their carrying values, based on their current and projected financial performance as well as the headroom from the previous annual goodwill and indefinite-lived intangible asset impairment assessment. For the select indefinite-lived intangible assets and reporting units within the Molding Technology Solutions reportable operating segment, an interim impairment assessment was triggered by macroeconomic conditions including an elevated interest rate and inflationary cost environment, and changing market fundamentals, coupled with business performance and a decrease in the Company’s market capitalization. Hot runner equipment had experienced a prolonged decline in demand and the outlook for a recovery of that demand remained uncertain. Additionally, certain competitors had made advancements in supplying high quality hot runner equipment. As a result of these indicators, during the third quarter of 2024, management developed a new five-year strategic plan for the select reporting units within the Molding Technology Solutions reportable operating segment, which established a revised downward outlook for net revenue, EBITDA, and operating cash flows. As a result of the change to expected future cash flows and comparable market information used in the market approach for estimating the fair value of one of the reporting units, the Company concluded that the carrying value for that reporting unit exceeded its fair value, resulting in a goodwill impairment charge of $238.0 during the third quarter of 2024. The pre-impairment goodwill balance for this reporting unit was $417.0. Additionally, under the relief-from-royalty fair value method, the Company concluded during the third quarter of 2024 that the carrying value of a trade name exceeded its fair value associated with that same reporting unit. As a result, an impairment charge of $27.0 was recorded for this trade name during the third quarter of 2024. The pre-impairment balance for this trade name was $88.6. The goodwill and indefinite-lived intangible asset impairment charges are nondeductible for tax purposes. Summary As a result of these factors and other factors discussed above, and the limited cushion (or headroom as commonly referred) due to recent acquisitions, goodwill and indefinite-lived intangible assets for the reporting units within the Molding Technology Solutions reportable operating segment are more susceptible to impairment risk. The estimated fair value, as calculated during the interim and annual impairment assessments, for all the reporting units within the Molding Technology Solutions reportable operating segment ranged from approximately 3% to 6% greater than their carrying value (versus 10% to 28% at the previous annual goodwill impairment assessment date). The estimated fair value, as calculated on July 1, 2024, for a reporting unit within the Advanced Process Solutions reportable operating segment was approximately 29% greater than its carrying value (this is a newly identified reporting unit as the result of the integration of recent acquisitions). Each of the other reporting units within the Advanced Process Solutions reportable operating segment had significant cushion or headroom at the annual impairment assessment date. The Company compared the total fair values of all reporting units to the Company's market capitalization on July 1, 2024, to determine if the fair values were reasonable. The Company's aggregate fair value of all reporting units exceeded the market capitalization at the annual goodwill impairment assessment date by approximately 6% (representing an implied control premium). Recent comparable (industrial companies) market transactions over the past 5 years would imply control premiums in a median range of 22% - 32% at the median (i.e., the premium of an offer price over the closing stock price immediately preceding an announced transaction), indicating a level of conservatism in in the Company’s annual goodwill impairment assessment. The Company is required to provide additional disclosures about fair value measurements as part of the Consolidated Financial Statements for each major category of assets and liabilities measured at fair value on a non-recurring basis (including impairment assessments). Goodwill and indefinite-lived intangible assets were valued using Level 3 inputs, which are unobservable by nature, and included internal estimates of future cash flows (income approach). Significant increases (decreases) in any of those unobservable inputs in isolation would result in a significantly higher (lower) fair value measurement.
Intangible assets	Intangible assets three
Equity method investments	Equity method investment — The Consolidated Financial Statements includes our 46% interest in TerraSource Holdings, LLC (“Holdings”), which is accounted for using the equity method of accounting as we have significant influence over the operating and financial policies of Holdings, however, do not control Holdings. When we record our proportionate share of net income, we record it as a reduction to Operating expenses in the Consolidated Statements of Operations and increase the carrying value of our equity method investment. Conversely, when we record our proportionate share of a net loss, if applicable we record it within Operating expenses in the Consolidated Statements of Operations and decrease the carrying value of our equity method investment. The value of our equity method investment in Holdings, which is recorded in Other long-term assets, was $9.2 and $5.1 at September 30, 2024 and 2023, respectively. We recorded our proportionate share of net income (loss) of Holdings of $5.8, $0.1, and $(2.1) for the years ended September 30, 2024, 2023, 2022, as a reduction decrease (increase) of Operating expenses.
Environmental liabilities	Environmental liabilities — Expenditures that relate to an existing condition caused by past operations which do not contribute to current or future net revenue generation are expensed. A reserve is established when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These reserves are determined without consideration of possible loss recoveries. Based on consultations with an environmental engineer, the range of liability is estimated based on current interpretations of environmental laws and regulations. A determination is made of the specific measures that are believed to be required to remediate the site, the estimated total cost to carry out the remediation plan, and the periods in which the Company will make payments toward the remediation plan. The Company does not make an estimate of inflation for environmental matters because the number of sites is relatively small, the Company believes the magnitude of costs to execute remediation plans is not significant, and the estimated time frames to remediate sites are not believed to be lengthy. Specific costs included in environmental expense and reserves include site assessment, remediation plan development, clean-up costs, post-remediation expenditures, monitoring, fines, penalties, and legal fees. The amount reserved represents the expected undiscounted future cash outflows associated with such plans and actions and the Company believes is not significant to Hillenbrand.
Self-insurance	Self-insurance — The Company is self-funded up to certain limits in the U.S. for product and general liability, workers compensation, and auto liability insurance programs, as well as certain employee health benefits including medical, drug, and dental. Claims covered by insurance have in most instances deductibles and self-funded retentions up to $0.5 per occurrence, depending upon the type of coverage and policy period. The Company’s policy is to estimate reserves for product and general liability, workers compensation, and auto liability based upon a number of factors, including known claims, estimated incurred but not reported claims, and outside actuarial analysis. The outside actuarial analysis is based on historical information along with certain assumptions about future events. These reserves are classified as other current liabilities and other long-term liabilities within the Consolidated Balance Sheets.
Pension and Other Postretirement Plans, Pensions, Policy	Pension benefit plans —
Treasury stock	Treasury stock consists of the Company’s common shares that have been issued but subsequently reacquired. The Company accounts for treasury stock purchases under the cost method. When these shares are reissued, the Company uses an average-cost method to determine cost. Proceeds in excess of cost are credited to additional paid-in capital.
Preferred stock	Preferred stock — The Company has authorized 1,000,000 shares of preferred stock (no par value), of which no shares were issued or outstanding at September 30, 2024 and 2023.
Accumulated other comprehensive loss	Accumulated other comprehensive loss — Includes all changes in Hillenbrand shareholders’ equity during the period except those that resulted from investments by or distributions to shareholders. Accumulated other comprehensive loss was comprised of the following amounts as of:
Revenue recognition	Revenue recognition — Net revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services and is recognized when performance obligations are satisfied under the terms of contracts with customers. A performance obligation is deemed to be satisfied by the Company when control of the product or service is transferred to the customer. The transaction price of a contract, or the amount the Company expects to receive upon satisfaction of the performance obligation, is determined by reference to the contract’s terms and includes adjustments, if applicable, for any variable consideration, such as sales discounts, which may require us to make estimates for the portion of these allowances that have yet to be credited or paid to our customers. The majority of sales discounts are included on the invoice to the customer and therefore, involved no estimation. If an estimate is required, these allowances are determined using the expected value method, which is typically based upon historical rates. The timing of revenue recognition for the contract’s performance obligation is either over time or at a point in time. We recognize revenue over time for contracts that have an enforceable right to collect payment for performance completed to date upon customer cancellation and provide one or more of the following: (i) service over a period of time, (ii) highly customized equipment, or (iii) parts which are highly engineered and have no alternative use. Net revenue generated from standard equipment and highly customized equipment or parts contracts without an enforceable right to payment for performance completed to date, as well as net revenue from non-specialized parts sales, is recognized at a point in time. We use the input method of “cost-to-cost” to recognize net revenue over time. Accounting for these contracts involves management judgment in estimating total contract revenue and cost. Contract revenue is largely determined by negotiated contract prices and quantities, modified by our assumptions regarding contract options and change orders. Contract costs are incurred over longer periods of time and, accordingly, the estimation of these costs requires judgment. We measure progress based on costs incurred to date relative to total estimated cost at completion. Incurred cost represents work performed, which corresponds with, and we believe thereby best depicts, the transfer of control to the customer. Contract costs include labor, material, and certain overhead expenses. Cost estimates are based on various assumptions to project the outcome of future events, including the complexity and length of the work to be performed, the cost of materials, and the performance of suppliers and subcontractors. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, and anticipated labor agreements. Net revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Anticipated losses on long-term manufacturing contracts are recognized immediately when such losses become evident, which is rare. We maintain financial controls over the customer qualification, contract pricing, and estimation processes designed to reduce the risk of contract losses. Standalone service net revenue is recognized either over time proportionately over the period of the underlying contract or as invoiced, depending on the terms of the arrangement. Standalone service net revenue is not material to the Company. Contract balances The Company often requires an advance deposit based on the terms and conditions of contracts with customers for many of its contracts. Payment terms generally require an upfront payment at the start of the contract, and the remaining payments during the contract or within a certain number of days of delivery. Typically, net revenue is recognized within one year of receiving an advance deposit. For certain contracts within the Advanced Process Solutions reportable operating segment where an advance payment is received greater than one year from expected net revenue recognition, or a portion of the payment due extends beyond one year, the Company has determined it does not constitute a significant financing component. The timing of revenue recognition, billings, and cash collections can result in trade receivables, advance payments, and billings in excess of net revenue recognized. Customer receivables include amounts billed and currently due from customers and are included in trade receivables, net, as well as unbilled amounts (contract assets) which are included in receivables from long-term manufacturing contracts on the Consolidated Balance Sheets. Amounts are billed in accordance with contractual terms or as work progresses in accordance with contractual terms. Unbilled amounts arise when the timing of billing differs from the timing of net revenue recognized, such as when contract provisions require specific milestones to be met before a customer can be billed. Unbilled amounts primarily relate to performance obligations satisfied over time when the cost-to-cost method is used and the revenue recognized exceeds the amount billed to the customer as there is not yet a right to payment in accordance with contractual terms. Unbilled amounts are recorded as a contract asset when the net revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. Advance payments and billings in excess of net revenue recognized are included in liabilities from long-term manufacturing contracts and advances on the Consolidated Balance Sheets. Advance payments and billings in excess of net revenue recognized represent contract liabilities and are recorded when customers remit contractual cash payments in advance of us satisfying performance obligations under contractual arrangements, including those with performance obligations satisfied over time. Billings in excess of net revenue recognized primarily relate to performance obligations satisfied over time when the cost-to-cost method is used and revenue cannot yet be recognized as the Company has not completed the corresponding performance obligation. Contract liabilities become unrecognized when net revenue is recognized and the performance obligation is satisfied. The balance in receivables from long-term manufacturing contracts at September 30, 2024 and 2023 was $302.7 and $260.2, respectively. The change was driven by the impact of net revenue recognized prior to billings. The balance in the liabilities from long-term manufacturing contracts and advances at September 30, 2024 and 2023 was $315.2 and $388.5, respectively, and consists primarily of cash payments received or due in advance of satisfying performance obligations. Substantially all of the liabilities from long-term manufacturing contracts and advances at September 30, 2023 and 2022, were recognized as net revenue during the years ended September 30, 2024 and 2023. During the years ended September 30, 2024, 2023, and 2022, the adjustments related to performance obligations satisfied in previous periods were immaterial. Costs incurred to obtain a customer contract are not material to the Company. The Company elected to apply the practical expedient to not capitalize contract costs to obtain contracts with a duration of one year or less, which are expensed as incurred.
Cost of goods sold	Cost of goods sold consists primarily of purchased material costs, fixed manufacturing expense, variable direct labor, and overhead costs. It also includes costs associated with the distribution and delivery of products.
Research and development costs	Research and development costs are expensed as incurred as a component of operating expenses and were $36.7, $25.4, and $19.8 for the years ended September 30, 2024, 2023, and 2022, respectively.
Warranty costs	Warranty costs
Income taxes	Income taxes — The Company establishes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Consolidated Financial Statements. Deferred tax assets and liabilities are determined in part based on the differences between the accounting treatment of tax assets and liabilities under GAAP and the tax basis of assets and liabilities using statutory tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in statutory tax rates on deferred tax assets and liabilities is recognized in consolidated net income in the period that includes the enactment date. The Company continues to assert that most of the cash at its foreign subsidiaries represents earnings considered to be permanently reinvested for which deferred taxes have not been recorded in the Consolidated Financial Statements, as the Company does not intend, nor does the Company foresee a need, to repatriate these funds. The Company continues to actively evaluate its global capital deployment and cash needs. The Company has a variety of deferred income tax assets in numerous tax jurisdictions. The recoverability of these deferred income tax assets is assessed periodically, and valuation allowances are recognized if it is determined that it is more likely than not that the benefits will not be realized. When performing this assessment, the Company considers the ability to carryback losses to prior tax periods, future taxable income, the reversal of existing temporary differences, and tax planning strategies. The Company accounts for accrued interest and penalties related to unrecognized tax benefits in income tax expense.
Derivative financial instruments	Derivative financial instruments — The Company has hedging programs in place to manage its currency exposures. The objectives of the Company’s hedging programs are to mitigate exposures in gross margin and non-functional-currency-denominated assets and liabilities. Under these programs, the Company uses derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates. These include foreign currency exchange forward contracts, which generally have terms up to 24 months. Additionally, the Company periodically enters into interest rate swaps to manage or hedge the risks associated with indebtedness and interest payments. The Company’s objectives in using these interest rate swaps are to add stability to interest expense and to manage exposure to interest rate movements. Contracts designated as cash flow hedges for customer orders or intercompany purchases have an offsetting tax-adjusted amount in accumulated other comprehensive loss. Foreign exchange contracts intended to manage foreign currency exposures within the Consolidated Balance Sheets have an offsetting amount recorded in operating expenses. The cash flows from such hedges are presented in the same category in the Consolidated Statement of Cash Flows as the items being hedged. Hillenbrand participates in cross-currency swap agreements aiming to hedge the variability in the movement of foreign currency exchange rates for its operations in Europe, while simultaneously lowering the Company’s overall borrowing costs. The maturity dates of these agreements range from 2027 to 2029. These agreements qualify for hedge accounting and accordingly the changes in fair value of the derivatives are recorded in other comprehensive (loss) income and remain in accumulated other comprehensive loss attributable to Hillenbrand in shareholders’ equity until the hedged item is recognized in earnings. We assess the effectiveness of cross-currency swap contracts using the spot method, and the difference between the interest rate received and paid under the cross-currency swap agreements is recorded in interest expense, net, in the Consolidated Statements of Operations. As a result of participating in these cross-currency swap agreements, Hillenbrand recorded a reduction in interest expense, net of $3.9 and $0 during the years ended September 30, 2024 and 2023, respectively. Hillenbrand presents the cross-currency swap agreements’ periodic settlements in operating activities in the Consolidated Statements of Cash Flows. The Company measures all derivative instruments at fair value and reports them on the Consolidated Balance Sheets as assets or liabilities. Changes in the fair value of derivatives are accounted for depending on the intended use of the derivative, designation of the hedging relationship, and whether or not the criteria to apply hedge accounting have been satisfied. If a derivative is designated as a fair value hedge, the gain or loss on the derivative and the offsetting loss or gain on the hedged asset or liability are recognized in earnings. For derivative instruments designated as a cash flow hedge, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive loss and reclassified to earnings in the same period that the hedged transaction affects earnings. The portion of the gain or loss that does not qualify for hedge accounting is immediately recognized in earnings. The aggregate notional value of the cross currency swap agreements was $727.8 and $0 at September 30, 2024 and 2023, respectively. The aggregate notional value of the foreign currency exchange forward contract derivatives was $172.5 and $164.6 at September 30, 2024 and 2023, respectively. The carrying value of all of the Company’s derivative instruments
Financing Receivable	Other financial instruments — Supply chain financing programs The Company has agreements with third-party financial institutions to facilitate supply chain finance (“SCF”) programs. The SCF programs allow qualifying suppliers to sell their receivables, on an invoice level at the selection of the supplier, from the Company to the financial institutions and negotiate their outstanding receivable arrangements and associated fees directly with the financial institutions. Hillenbrand is not party to the agreements between the supplier and the financial institutions. The supplier invoices that have been confirmed as valid under the SCF programs require payment in full by the financial institutions to the supplier by the original maturity date of the invoice, or discounted payment at an earlier date as agreed upon with the supplier. The Company’s obligations to its suppliers, including amounts due and scheduled payment terms, are not impacted by a supplier’s participation in the SCF programs. All outstanding amounts related to suppliers participating in the SCF programs are recorded upon confirmation with the third-party financial institutions in trade accounts payable in the Consolidated Balance Sheets, and associated payments are included in cash used in operating activities in the Consolidated Statements of Cash Flows. The Company’s outstanding obligations included in trade accounts payable as of September 30, 2024 and 2023, were $16.0 and $29.1, respectively. Trade receivables financing agreements The Company sells a small percentage of our trade receivables to outside financial institutions in the normal course of business. These trade receivable financing agreements are accounted for as a sale of assets under the provisions of Accounting Standards Codification (“ASC”) 860, Transfers and Servicing ("ASC 860"). During the year ended September 30, 2024, the Company executed an amendment of its trade receivables financing agreement (as amended, the “Amended Agreement”) with a financial institution. In accordance with ASC 860 this Amended Agreement is deemed a true sale, as the Company retains no rights or interest and has no obligations with respect to the trade receivables, and has no continuing involvement with the trade receivables once transferred to the financial institution. As part of the Amended Agreement, we receive the majority of the proceeds of the trade receivables sold to the financial institution upon sale in cash (level 1 fair value measurement) with the remaining portion of the proceeds held by the financial institution as a deferred purchase price (“DPP”) (level 2 fair value measurement) until the collection of the trade receivables sold. The DPP receivables are ultimately realized by the Company following the collection of the underlying trade receivables sold to the financial institution (typically within 90 - 120 days). As defined in the Amended Agreement, the financial institution is responsible for any credit risk associated with the sold trade receivables. There is no limit on the amount of trade receivables that can be sold under the Amended Agreement; however, all trade receivables must be accepted by the financial institution prior to sale. Sales of trade receivables under the Amended Agreement and other trade receivable factoring arrangements were $250.0, $25.4, and $28.2, and cash collections from customers on trade receivables sold were $243.4, $25.4 and $28.2 during the fiscal years ended September 30, 2024, 2023 and 2022, respectively. The Company acts as a servicer (collects customer cash on behalf of the financial institution) for one of its trade receivables factoring arrangements. The servicing fee associated with this trade receivables factoring arrangement was not material to the Company for the years ended September 30, 2024, 2023, and 2022. Amounts collected on behalf of the financial institution under this trade receivables factoring arrangement and owed to the financial institution were $3.1 and $0.2 at September 30, 2024 and 2023, respectively. The loss on the sale of trade receivables under the Amended Agreement and other trade receivables factoring arrangements was not material to the Company for the years ended September 30, 2024, 2023, and 2022. The following roll forward summarizes the activity related to the DPP receivables: Year Ended September 30, 2024 Beginning DPP receivables balance $ — Non-cash additions to DPP receivables 32.3 Cash collections on DPP receivables (25.6) Ending DPP receivables balance $ 6.7
Business acquisitions and related business acquisition and integration costs	Business acquisitions and related business acquisition and integration costs — Assets and liabilities associated with business acquisitions are recorded at fair value, using the acquisition method of accounting. The Company allocates the purchase price of acquisitions based upon the fair value of each component, which may be derived from observable or unobservable inputs and assumptions. The Company generally utilizes third-party valuation specialists to assist us in this allocation. Initial purchase price allocations are preliminary and subject to revision within the measurement period, generally not to exceed one year from the date of acquisition. Business acquisition and integration costs are expensed as incurred and are reported as a component of cost of goods sold and operating expenses depending on the nature of the cost. The Company defines these costs to include finder’s fees, advisory, legal, accounting, valuation, and other professional or consulting fees, as well as travel associated with investigating opportunities (including acquisition and divestitures). Business acquisition and integration costs also include costs associated with acquisition tax planning, retention bonuses, and related integration costs. These costs exclude the ongoing expenses of the Company’s business development department.
Restructuring costs	Restructuring costs may occur when the Company takes action to exit or significantly curtail a part of the Company’s operations or change the deployment of assets or personnel. A restructuring charge can consist of an impairment or accelerated depreciation of affected assets, severance costs associated with reductions to the workforce, costs to terminate an operating lease or contract, and charges for legal obligations for which no future benefit will be derived.
Recently adopted accounting standards	Recently adopted accounting standards — In September 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50); Disclosure of Supplier Finance Program Obligations . ASU 2022-04 requires entities that use supplier finance programs to disclose information about the nature and potential magnitude of the programs, activity during the period, and changes from period to period. ASU 2022-04 does not affect the recognition, measurement, or consolidated financial statement presentation of obligations covered by supplier finance programs. The Company adopted ASU 2022-04 effective October 1, 2023. The adoption of ASU 2022-04 did not have a material effect on our Consolidated Financial Statements and related disclosures. See the other financial instruments section above for further details.
