FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts and can generally be identified by words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” "future," “goal,” “intend,” “may,” “outlook,” “plan,” “position,” “possible,” “potential,” “project,” “should,” “target,” “will,” “would,” and similar expressions or variations thereof, or the negative thereof, but these terms are not the exclusive means of identifying such statements. Forward-looking statements are based on management’s expectations and assumptions as of the date of this report and are not guarantees of future performance. You are cautioned not to place undue reliance on our forward-looking statements.

Forward-looking statements may relate to a number of matters, including expectations regarding revenue, margins, expenses, earnings, tax provisions, cash flows, pension obligations, share repurchases or other statements regarding economic conditions or our business outlook; statements regarding capital expenditures and plans, projects, investment opportunities, and potential transactions that are subject to ongoing negotiations and their expected impact and timing; strategies and objectives for our future operations, including our ability to win new projects and execute the projects in our backlog; and statements regarding our expectations with respect to pending legal claims or disputes. While forward-looking statements are made in good faith and based on assumptions, expectations and projections that management believes are reasonable based on currently available information, actual performance and financial results may differ materially from projections and estimates expressed in the forward-looking statements because of many factors, including, without limitation:

•changes in global or regional economic conditions, inflation, and supply and demand dynamics in the market segments we serve, including demand for technologies and projects to limit the impact of global climate change;

•changes in the financial markets may affect the availability and terms on which we may obtain financing;

•the ability to execute agreements with customers and implement price increases to offset cost increases;

•disruptions to our supply chain and related distribution delays and cost increases;

•risks associated with having extensive international operations, including political risks, risks associated with unanticipated government actions and risks of investing in developing markets;

•project delays, scope changes, cost escalations, contract terminations, customer cancellations, or postponement of projects and sales;

•our ability to safely develop, operate, and manage costs of large-scale and technically complex projects;

•the future financial and operating performance of major customers, joint ventures, and equity affiliates;

•our ability to safely and effectively develop, implement, and operate new technologies and to market products produced utilizing new technologies;

•our ability to execute the projects in our backlog and refresh our pipeline of new projects;

•tariffs, economic sanctions and regulatory activities in jurisdictions in which we, our affiliates and joint ventures, and our customers and other counterparties operate;

•the impact of environmental, tax, safety, or other legislation, as well as regulations and other public policy initiatives affecting our business and the business of our affiliates and related compliance requirements, including legislation, regulations, or policies intended to address global climate change;

•changes in tax rates and other changes in tax law;

•safety incidents relating to our operations;

•the timing, impact, and other uncertainties relating to acquisitions, divestitures, joint venture activities and other commercial transactions, as well as our ability to integrate acquisitions and separate divested businesses, respectively;

3

FORWARD-LOOKING STATEMENTS (CONTINUED)

•risks relating to cybersecurity incidents, including risks from the interruption, failure or compromise of our information systems or those of our business partners or service providers;

•catastrophic events, such as natural disasters and extreme weather events, pandemics and other public health crises, acts of war, including Russia’s invasion of Ukraine, the conflict with Iran and other new and ongoing conflicts in the Middle East, or terrorism;

•the impact on our business and customers of price fluctuations in oil and natural gas and disruptions in markets and the economy due to oil and natural gas price volatility;

•costs and outcomes of legal or regulatory proceedings and investigations;

•asset impairments due to economic conditions or specific events;

•significant fluctuations in inflation, interest rates, and foreign currency exchange rates from those currently anticipated;

•damage to facilities, pipelines or delivery systems, including those we are constructing or that we own or operate for third parties;

•availability and cost of electric power, natural gas, and other raw materials; and

•the commencement and success of any productivity and operational improvement programs.

In addition to the foregoing factors, forward-looking statements contained herein are qualified with respect to the risks disclosed elsewhere in this document, including in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations, and Item 3, Quantitative and Qualitative Disclosures About Market Risk, as well as with respect to the risks described in Item 1A, Risk Factors, to our Annual Report on Form 10-K for the fiscal year ended 30 September 2025 and in Part II, Item 1A, Risk Factors, of this Quarterly Report on Form 10-Q. Any of these factors, as well as those not currently anticipated by management, could cause our results of operations, financial condition or liquidity to differ materially from what is expressed or implied by any forward-looking statement. Except as required by law, we disclaim any obligation or undertaking to update or revise any forward-looking statements contained herein to reflect any change in assumptions, beliefs, or expectations or any change in events, conditions, or circumstances upon which any such forward-looking statements are based.

1. BASIS OF PRESENTATION AND MAJOR ACCOUNTING POLICIES

As used in this report, unless the context indicates otherwise, the terms “we”, “our”, “us”, the “Company”, "Air Products", or “registrant” include our controlled subsidiaries and affiliates.

Basis of Presentation

The interim consolidated financial statements of Air Products and Chemicals, Inc. and its controlled subsidiaries included herein have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). The accompanying notes are an integral part of these statements.

Certain information normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") has been condensed or omitted as permitted under such rules and regulations. In management’s opinion, the accompanying statements reflect adjustments necessary to fairly present our financial position, results of operations, and cash flows for the periods indicated and contain adequate disclosures to make the information presented not misleading. Adjustments included herein are of a normal, recurring nature unless otherwise disclosed in the notes to the interim consolidated financial statements. Certain prior period information has been reclassified to conform to the current year presentation.

To fully understand the basis of presentation, the interim consolidated financial statements and related notes included herein should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended 30 September 2025 (the "2025 Form 10-K"), which was filed with the SEC on 20 November 2025. Results of operations for interim periods are not necessarily indicative of the results of operations for a full year.

Major Accounting Policies

Refer to our 2025 Form 10-K for a description of our major accounting policies. There were no significant changes to these accounting policies during the first six months of fiscal year 2026.

Estimates and Assumptions

Preparation of the interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in these statements and the accompanying notes. Actual results could differ from those estimates.

2. NEW ACCOUNTING GUIDANCE

New Accounting Guidance to be Implemented

Climate-Related Disclosures

In March 2024, the SEC issued Release No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors", which includes final rules for providing annual qualitative and quantitative disclosures regarding certain climate-related topics. As a result of legal challenges, the SEC issued an order in April 2024 to stay the effectiveness of the rules pending the completion of judicial review of the consolidated challenges before the United States Court of Appeals for the Eighth Circuit.

The SEC subsequently announced its withdrawal of its legal defense to such challenges in March 2025; however, the rules have not been formally rescinded by the SEC. In April 2025, the appellate court suspended its proceedings indefinitely and directed the SEC to file a status report outlining its next steps. In response, the SEC stated in July 2025 that it does not intend to revisit the rules and requested the court to rule on the pending petitions.

In September 2025, the appellate court declined the SEC's request and placed the litigation in abeyance, which will remain in effect until the SEC reconsiders the rules by notice-and-comment rulemaking or renews its defense. We continue to monitor these developments.

Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740)—Improvements to Income Tax Disclosures”, to expand income tax disclosures, primarily through disaggregation requirements for the rate reconciliation and income taxes paid. The update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2026, although early adoption is permitted. The amendments should be applied on a prospective basis with a retrospective option. We are evaluating the impact this update will have on our disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires additional disclosures of certain costs and expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization, as well as selling expenses in the notes to the financial statements. In January 2025, the FASB clarified that the update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2028 as well as interim periods thereafter, although early adoption is permitted. The amendments should be applied either prospectively after the effective date or retrospectively to any or all periods presented. We are evaluating the impact this update will have on our disclosures.

Measurement of Credit Losses for Accounts Receivable and Contract Assets

In July 2025, the FASB issued ASU 2025-09, “Measurement of Credit Losses for Accounts Receivable and Contract Assets”, which allows an entity to elect a practical expedient to assume that current conditions as of the balance sheet date do not change when estimating expected credit losses. This update will be effective at the beginning of fiscal year 2027, although early adoption is permitted. The amendments should be applied on a prospective basis. We are evaluating the implications of this update. At this time, we do not expect it will have a material impact on our financial statements.

Accounting for Internal-Use Software

In September 2025, the FASB issued ASU 2025-06, “Targeted Improvements to the Accounting for Internal-Use Software”, which establishes criteria for commencing cost capitalization for software projects. This update will be effective at the beginning of fiscal year 2029, although early adoption is permitted. The amendments can be applied prospectively, retrospectively, or via a modified prospective transition method. We are evaluating the impact this update will have on our financial statements.

Government Grants

In December 2025, the FASB issued ASU 2025-10, “Accounting for Government Grants Received by Business Entities”, which provides guidance on the recognition, measurement, and presentation of government grants. This update will be effective at the beginning of fiscal year 2030, although early adoption is permitted. The amendments can be applied on a modified prospective approach, modified retrospective approach, or a full retrospective approach. We are evaluating the impact this update will have on our financial statements.

Interim Reporting

In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements”. This guidance addresses the form and content of interim financial statements, lists interim disclosures required by other codification topics, and establishes a principle for disclosing events since the end of the last annual reporting period that have a material impact. This update will be effective for interim periods beginning in fiscal year 2029, although early adoption is permitted. The ASU can be applied prospectively or retrospectively. We are evaluating the impact this update will have on our disclosures.

3. VARIABLE INTEREST ENTITIES

We are the primary beneficiary of the NEOM Green Hydrogen Company joint venture ("NGHC"), a variable interest entity ("VIE") that is consolidated in our Middle East and India segment. We are not the primary beneficiary of any other material VIEs.

Our other material VIEs are those in which we hold variable interests but are not the primary beneficiary. We have an equity interest and exercise significant influence in the Jazan Integrated Gasification and Power Company joint venture ("JIGPC"), which we account for as an equity method investment in our Middle East and India segment. We have no equity interest in World Energy, LLC ("World Energy"), but hold a variable interest through a financing receivable that was fully reserved in connection with our exit from the sustainable aviation fuel ("SAF") expansion project during the second quarter of fiscal year 2025.

NGHC Joint Venture

The NEOM Green Hydrogen Project is a multi-billion dollar green hydrogen-based ammonia production facility that is being constructed in NEOM City, Saudi Arabia. Owned and operated by NGHC, the facility will be powered by renewable energy to produce green ammonia for Air Products as the exclusive offtaker under a long-term take-if-tendered agreement.

Air Products is an equal owner in NGHC with our joint venture partners, ACWA Power and NEOM Company. While we only hold one-third of the voting interests in the joint venture, substantially all the activities of the joint venture involve or are conducted on behalf of Air Products. Since we have disproportionately few voting rights relative to our economic interests in the joint venture, we determined that NGHC is a VIE. In addition, we determined that we are the primary beneficiary of NGHC since we have the power to unilaterally direct certain significant activities, including key design and construction decisions, and we share power with our joint venture partners related to other activities that are significant to the economic performance of NGHC. Therefore, we consolidate NGHC within the Middle East and India segment.

Under the project financing discussed below, the assets of NGHC can only be used to settle obligations of the joint venture, and creditors of NGHC do not have recourse to the general credit of Air Products. A table summarizing balances associated with NGHC as reflected on our consolidated balance sheets is provided on page 15.

Project Financing

In May 2023, NGHC finalized the $6.7 billion engineering, procurement, and construction agreement, naming Air Products as the main contractor and system integrator for the facility. To support the project, NGHC secured project financing that is non-recourse to Air Products of approximately $6.1 billion, which is expected to fund about 73% of the project and is being drawn over the construction period. At the same time, NGHC secured additional credit facilities totaling approximately $500, primarily for NGHC's working capital needs. These facilities are also non-recourse to Air Products. Total principal borrowings were $5.4 billion and $4.9 billion as of 31 March 2026 and 30 September 2025, respectively. Long-term principal borrowings of approximately $415 during the first six months of fiscal year 2026 were primarily drawn under a 2.00% stated-rate Saudi Riyal facility.

The borrowings discussed above are primarily from long-term facilities that are presented net of unamortized discounts and debt issuance costs within "Long-term debt" on our consolidated balance sheets. Short-term borrowings were $46.5 and $24.0 as of 31 March 2026 and 30 September 2025, respectively, under a variable-rate Saudi Riyal facility that carried an interest rate of 5.02% as of 31 March 2026.

14

Interest Rate Swaps

In May 2023, NGHC entered into floating-to-fixed interest rate swaps designed to hedge long-term variable-rate debt facilities available under the project financing during the construction period. In fiscal year 2024, we discontinued cash flow hedge accounting for certain swaps due to changes in the anticipated drawdown timeline for the hedged borrowings. As a result of the de-designation, unrealized gains and losses related to the affected swaps were recorded in "Other non-operating income (expense), net" on our consolidated income statements.

During the three months ended 31 March 2025, we recorded an unrealized loss of $11.5 ($7.5 attributable to our noncontrolling partners, or $3.0 attributable to Air Products after tax). For the six months ended 31 March 2025, the total amount recorded was a net unrealized gain of $27.3 ($17.7 attributable to our noncontrolling partners, or $7.3 attributable to Air Products after tax).

We re-designated the affected swaps as cash flow hedges when the outstanding borrowings under the available project financing became commensurate with the swaps’ notional values. As of 1 January 2026, all swaps were re-designated as cash flow hedges. The unrealized gain on swaps that remained de-designated during the first quarter of fiscal year 2026 was not material.

NGHC Balance Sheet

JIGPC Joint Venture

JIGPC is a joint venture with Saudi Aramco Power Company (a subsidiary of Aramco), ACWA Power, and Air Products Qudra (“APQ”). JIGPC entered into project financing to purchase power blocks, gasifiers, air separation units, syngas cleanup assets, and utilities to supply electricity, steam, hydrogen, and utilities to Aramco’s refinery and terminal complex under a 25-year agreement, which commenced in the first quarter of fiscal year 2022. JIGPC recorded financing receivables upon acquisition of the assets and recognizes financing income over the supply term.

We determined JIGPC is a VIE for which we exercise significant influence but are not the primary beneficiary as we do not have the power to direct the activities that are most significant to its economic performance. Instead, these activities, including plant dispatch, operating and maintenance decisions, budgeting, capital expenditures, and financing, require unanimous approval of the owners or are controlled by the customer. Accordingly, we account for our 55% investment, which includes 4% that is attributable to the noncontrolling partner of APQ, under the equity method within the Middle East and India segment.

Our loss exposure is limited to the carrying value of our investment in the joint venture which, including amounts attributable to noncontrolling interests, totaled approximately $3.0 billion and $3.1 billion as of 31 March 2026 and 30 September 2025, respectively.

Our total investment in JIGPC primarily consists of shareholder loans that qualify as in-substance common stock in the joint venture. Certain shareholders receive a preferred cash distribution pursuant to the joint venture agreement, which specifies each shareholder’s share of income after considering the amount of cash available for distribution. As such, the earnings attributable to Air Products may not be proportionate to our ownership interest in the venture.

World Energy

In November 2023, we purchased an SAF facility in Paramount, California, from World Energy and accounted for the transaction as a financing arrangement because the agreement contained an embedded sales-type lease. Additionally, we entered into a Master Project Agreement ("MPA") that included terms for operation of the acquired facility as well as amended terms for the construction and operation of an SAF expansion project subject to construction at the same location. We determined that World Energy is a VIE, and our financing receivable represented a variable interest in World Energy. We are not the primary beneficiary as we did not control key operating decisions.

In February 2025, we terminated the MPA and announced our decision to exit the project. Cumulative project exit charges recorded in connection with this decision total approximately $1.9 billion, the majority of which were recognized in the second quarter of fiscal year 2025 and primarily related to the write-down of plant and equipment. We have no further loss exposure related to our variable interest in World Energy because these charges also included the establishment of an allowance for credit loss equal to the value of the financing receivable. However, future impacts to earnings may occur as we finalize our exit from the project.

Project exit charges related to World Energy were recorded with other business and asset actions discussed in Note 4, Business and Asset Actions.

4. BUSINESS AND ASSET ACTIONS

Our consolidated income statement for the six months ended 31 March 2026 includes charges for business and asset actions of $28.3 ($24.6 after tax) related to project exit decisions reached in fiscal year 2025. Of these charges, $22.0 were recorded to operating income to update cost estimates as we settle project‑related commitments and dispose of associated assets, and $6.3 were recorded in "Other non‑operating income (expense), net" for losses on cross‑currency interest rate swaps terminated in connection with the early repayment of related intercompany loans for one of the affected gasification projects in China. No additional charges were recorded during the second quarter of fiscal year 2026.

Our consolidated prior-year income statements for the three and six months ended 31 March 2025 included charges of approximately $2.9 billion, reflecting initial project exit charges as well as costs incurred in connection with our global cost reduction plan. Of these charges, $2.3 billion was attributable to Air Products after tax ($3.5 attributable to noncontrolling partners), including $6.8 recorded in equity affiliates’ income related to an other‑than‑temporary impairment of a joint venture in China formed to develop clean hydrogen infrastructure in the region.

Project Exit Costs

Project exit decisions reached in fiscal year 2025 were part of a review initiated by our Board of Directors and Chief Executive Officer to focus resources on projects we believe will deliver the greatest value to our shareholders. These actions primarily affected clean‑energy generation and distribution projects, including three U.S.-based projects within the Americas segment, as well as several smaller-scale projects across our global portfolio. The exit decisions were driven by several factors, including challenging commercial conditions and unfavorable regulatory actions, as well as customer‑related challenges for two coal gasification plants in China that resulted in assets and liabilities being classified as held for sale. Assets held for sale as of 31 March 2026 and 30 September 2025 primarily included plant and equipment. We continue to pursue the sale of these assets and remain engaged in marketing and negotiation efforts.

Cumulative charges incurred in connection with these decisions total approximately $3.6 billion, the majority of which were recognized in the second quarter of fiscal year 2025. Noncash expenses of approximately $3.3 billion included $2.5 billion to write down plant and equipment, with the remainder primarily related to other assets associated with our exit from the SAF expansion project with World Energy as discussed in Note 3, Variable Interest Entities.

Cash obligations primarily relate to costs to terminate contractual commitments and settle asset retirement obligations. Total cash outflows are expected to be approximately $360 once the actions are fully implemented. Approximately $240 has been paid through 31 March 2026.

The table below provides a reconciliation of the beginning and ending liability balances associated with project exit activities, which are reflected within “Payables and Accrued Liabilities” on our consolidated balance sheets:

Amount accrued as of 30 September 2025	$178.3
Changes in estimates	9.3
Cash payments	(67.0)
Amount accrued as of 31 March 2026	$120.6

Both the held-for-sale assets and other marketable plant and equipment were subject to Level 3 fair value measurements due to the use of significant unobservable inputs. There were no material changes to the valuation assumptions during the first six months of fiscal year 2026. Refer to Note 9, Fair Value Measurements, for additional information.

Estimates related to the actions described above reflect our best judgment based on information available at the time the charges were recorded. Final settlement of these items may differ materially from current estimates, which could impact our consolidated financial statements in future periods. While we expect the related exit activities to be substantially completed in fiscal year 2026, we cannot predict the occurrence of future events and circumstances that could extend the timing of certain actions beyond this period. In addition, the related project review remains ongoing and may result in additional costs in future periods.

17

Global Cost Reduction Plan

In June 2023, we initiated a global cost reduction plan that provides severance and other postemployment benefits to employees designated for involuntary separation. In accordance with our accounting policy, we recognize related costs in the period management formally commits to a defined set of actions under the plan. Benefits are determined based on the terms of our established ongoing benefit arrangements. Since the plan was initiated, we have incurred cumulative costs totaling $207.7 for approximately 3,600 employees globally. No costs were recorded for the plan during the first half of fiscal year 2026. Our consolidated prior-year income statement reflects costs of $66.1 for actions identified during the second quarter of fiscal year 2025.

The table below provides a reconciliation of the beginning and ending liability balances associated with our global cost reduction plan, which are reflected within “Payables and Accrued Liabilities” on our consolidated balance sheets:

Amount accrued as of 30 September 2025	$101.6
Cash payments	(29.8)
Currency translation adjustment	(0.5)
Amount accrued as of 31 March 2026	$71.3

The remaining liability as of 31 March 2026 relates to employees identified during fiscal year 2025. We expect implementation of these actions to be substantially complete by the end of fiscal year 2026. However, position eliminations are subject to legal requirements that vary by jurisdiction, which may extend this process beyond this period in certain cases.

5. REVENUE RECOGNITION

The majority of our revenue is generated from our sale of gas customers within the regional industrial gases segments. We distribute product to our industrial gas customers through either our on-site or merchant supply mode depending on various factors, including the customer's volume requirements and location. We also design and manufacture equipment for air separation, hydrocarbon recovery and purification, and liquid helium and liquid hydrogen transport and storage. The Corporate and other segment serves our sale of equipment customers.

Disaggregation of Revenue

The tables provided below present our consolidated sales disaggregated by supply mode for each of our reportable segments. We believe this presentation best depicts the nature, timing, type of customer, and contract terms for our sales.

Interest income associated with financing and lease arrangements accounted for approximately 1% of our total consolidated sales for the periods presented.

Remaining Performance Obligations

As of 31 March 2026, the transaction price allocated to remaining performance obligations is estimated to be approximately $28 billion. This amount includes fixed-charge contract provisions associated with our on-site and sale of equipment supply modes. We estimate that approximately half of this revenue will be recognized over the next five years and the balance thereafter.

Our remaining performance obligations do not include (1) expected revenue associated with new on-site plants that are not yet on-stream; (2) consideration associated with contracts that have an expected duration of less than one year; and (3) variable consideration for which we recognize revenue at the amount to which we have the right to invoice, including energy cost pass-through to customers.

In the future, actual amounts will differ due to events outside of our control, including, but not limited to, inflationary price escalations; currency exchange rates; and amended, terminated, or renewed contracts.

Contract Balances

The table below details balances arising from contracts with customers:

		31 March	30 September
	Balance Sheet Location	2026	2025

8. FINANCIAL INSTRUMENTS

Currency Price Risk Management

Our earnings, cash flows, and financial position are exposed to foreign currency risk from foreign currency-denominated transactions and net investments in foreign operations. It is our policy to seek to minimize our cash flow volatility from changes in currency exchange rates. This is accomplished by identifying and evaluating the risk that our cash flows will change in value due to changes in exchange rates and by executing strategies necessary to manage such exposures. Our objective is to maintain economically balanced currency risk management strategies that provide adequate downside protection.

Forward Exchange Contracts

We enter into forward exchange contracts to reduce the cash flow exposure to foreign currency fluctuations associated with highly anticipated cash flows and certain firm commitments, such as the purchase of plant and equipment. We also enter into forward exchange contracts to hedge the cash flow exposure on intercompany loans and third-party debt. This portfolio of forward exchange contracts consists primarily of the U.S. Dollar and each of the Chinese Renminbi, Canadian Dollar, and South Korean Won. The maximum remaining term of any forward exchange contract currently outstanding and designated as a cash flow hedge at 31 March 2026 is 2.3 years.

Forward exchange contracts are also used to hedge the value of investments in certain foreign subsidiaries and affiliates by creating a liability in a currency in which we have a net equity position. The primary currency pair in this portfolio of forward exchange contracts is the U.S. Dollar and Chilean Peso.

We also utilize forward exchange contracts that are not designated as hedges. These contracts are used to economically hedge foreign currency-denominated monetary assets and liabilities, primarily working capital. The primary objective of these forward exchange contracts is to protect the value of foreign currency-denominated monetary assets and liabilities from the effects of volatility in foreign exchange rates that might occur prior to their receipt or settlement. This portfolio of forward exchange contracts consists of multiple foreign currency pairs, with a profile that changes from time to time depending on our business activity and sourcing decisions.

The table below summarizes our outstanding currency price risk management instruments:

	31 March 2026		30 September 2025
	US$ Notional	Years Average Maturity	US$ Notional	Years Average Maturity
Forward Exchange Contracts:
Cash flow hedges	$4,250.1	0.5	$3,625.5	0.6
Net investment hedges	76.8	0.3	73.9	0.8
Not designated	2,105.2	1.2	2,968.6	1.2
Total Forward Exchange Contracts	$6,432.1	0.7	$6,668.0	0.9

We also use foreign currency-denominated debt to hedge the foreign currency exposures of our net investment in certain foreign subsidiaries. The designated foreign currency-denominated debt and related accrued interest was €3,142.0 million ($3,631.9 million) at 31 March 2026 and €3,188.1 million ($3,741.5 million) at 30 September 2025. The designated foreign currency-denominated debt is presented within "Long-term debt" on our consolidated balance sheets.

Debt Portfolio Management

It is our policy to identify, on a continuing basis, the need for debt capital and to evaluate the financial risks inherent in funding the Company with debt capital. Reflecting the result of this ongoing review, we manage our debt portfolio and hedging program with the intent to (1) reduce funding risk with respect to borrowings made by us to preserve our access to debt capital and provide debt capital as required for funding and liquidity purposes, and (2) manage the aggregate interest rate risk and the debt portfolio in accordance with certain debt management parameters.

22

Interest Rate Management Contracts

We enter into interest rate swaps to change the fixed/variable interest rate mix of our debt portfolio in order to maintain the percentage of fixed- and variable-rate debt within the parameters set by management. In accordance with these parameters, the agreements are used to manage interest rate risks and costs inherent in our debt portfolio. Our interest rate management portfolio generally consists of fixed-to-floating interest rate swaps (which are designated as fair value hedges), pre-issuance interest rate swaps and treasury locks (which hedge the interest rate risk associated with anticipated fixed-rate debt issuances and are designated as cash flow hedges), and floating-to-fixed interest rate swaps (which are designated as cash flow hedges). As of 31 March 2026, the outstanding interest rate swaps were denominated in U.S. Dollars. The notional amount of the interest rate swap agreements is equal to or less than the designated debt being hedged. When interest rate swaps are used to hedge variable-rate debt, the indices of the swaps and the debt to which they are designated are the same. It is our policy not to enter into any interest rate management contracts which lever a move in interest rates on a greater than one-to-one basis.

Cross Currency Interest Rate Swap Contracts

We enter into cross currency interest rate swap contracts when our risk management function deems necessary. These contracts may entail both the exchange of fixed- and floating-rate interest payments periodically over the life of the agreement and the exchange of one currency for another currency at inception and at a specified future date. The contracts are used to hedge either certain net investments in foreign operations or non-functional currency cash flows related to intercompany loans. The current cross currency interest rate swap portfolio consists of fixed-to-fixed swaps primarily between the U.S. Dollar and each of the Chinese Renminbi, South Korean Won, and New Taiwan Dollar.

The table below summarizes our outstanding interest rate management contracts and cross currency interest rate swaps:

	31 March 2026						30 September 2025

(A)We temporarily discontinued cash flow hedge accounting for certain floating-to-fixed interest rate swaps related to project financing for the NEOM Green Hydrogen Project beginning in the third quarter of fiscal year 2024 due to changes in the anticipated drawdown timeline for the hedged borrowings. As of 1 January 2026, all swaps were re-designated as cash flow hedges. Refer to Note 3, Variable Interest Entities, for additional information.

The cash flows related to derivative contracts are generally reported in the operating activities section of the consolidated statements of cash flows.

Credit Risk-Related Contingent Features

Certain derivative instruments are executed under agreements that require us to maintain a minimum credit rating with both Standard & Poor’s and Moody’s. If our credit rating falls below this threshold, the counterparty to the derivative instruments has the right to request full collateralization on the derivatives’ net liability position. The net liability position of derivatives with credit risk-related contingent features was $91.3 and $43.3 as of 31 March 2026 and 30 September 2025, respectively. Because our current credit rating is above the various pre-established thresholds, no collateral has been posted on these liability positions.

Counterparty Credit Risk Management

We execute financial derivative transactions with counterparties that are highly rated financial institutions, all of which are investment grade at this time. Some of our underlying derivative agreements give us the right to require the institution to post collateral if its credit rating falls below the pre-established thresholds with Standard & Poor’s, Moody’s, or Fitch. The collateral that the counterparties would be required to post was $259.6 and $174.0 as of 31 March 2026 and 30 September 2025, respectively. No financial institution is required to post collateral at this time, as all have credit ratings at or above threshold.

9. FAIR VALUE MEASUREMENTS

Fair value is defined as an exit price, or the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows:

Level 1    — Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2    — Inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability.

Level 3    — Inputs that are unobservable for the asset or liability based on our own assumptions about the assumptions market participants would use in pricing the asset or liability.

The methods and assumptions used to measure the fair value of financial instruments are as follows:

Derivatives

The fair value of our interest rate management contracts and forward exchange contracts are quantified using the income approach and are based on estimates using standard pricing models. These models consider the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. These standard pricing models utilize inputs that are derived from or corroborated by observable market data such as interest rate yield curves as well as currency spot and forward rates; therefore, the fair value of our derivatives is classified as a Level 2 measurement. On an ongoing basis, we randomly test a subset of our valuations against valuations received from the transaction’s counterparty to validate the accuracy of our standard pricing models. Counterparties to these derivative contracts are highly rated financial institutions.

Refer to Note 8, Financial Instruments, for a description of derivative instruments, including details related to the balance sheet line classifications.

Long-term Debt, Including Related Party

The fair value of our debt is based on estimates using standard pricing models that consider the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. These standard valuation models utilize observable market data such as interest rate yield curves and currency spot rates; therefore, the fair value of our debt is classified as a Level 2 measurement.

The carrying amounts reported on the consolidated balance sheets for cash and cash items, trade receivables, payables and accrued liabilities, accrued income taxes, and short-term borrowings approximate fair value due to the short-term nature of these instruments. Accordingly, these items have been excluded from the above table.

Nonrecurring Fair Value Measurements – Project Exit Activities

We estimate the value of certain long-lived assets associated with exited projects using Level 3 inputs under the fair value hierarchy due to the absence of observable market prices and significant reliance on management judgment and estimation techniques. These assets are described below. For additional information regarding project exit activities, refer to Note 4, Business and Asset Actions.

Long-lived assets that met the held-for-sale criteria and are actively being marketed for sale.

Because there were no observable market prices available, fair value, including costs to sell, for long-lived assets that met the held-for-sale criteria was estimated using an internally developed discounted cash flow analysis, which resulted in an impairment charge of $350.6 in the fourth quarter of fiscal year 2025. There were no material changes to valuation assumptions during the first six months of fiscal year 2026. Any gain or loss from the sales will be recognized upon closing of any such transaction based on the carrying amounts classified as held for sale. Interim adjustments may be recorded prior to closing if market participant assumptions or other valuation inputs change, including updates to expected selling price or transaction timing.

Plant and equipment that did not meet the held‑for‑sale criteria but are capable of being sold through secondary equipment markets.

These assets were evaluated for recoverability in fiscal year 2025, and the resulting impairment loss of approximately $2.1 billion was recorded primarily during the second quarter using an orderly liquidation valuation approach. The impairment charge reflects the difference between the estimated liquidation value and the net book value of the assets as of 31 March 2025. There were no material changes in the estimated net realizable value for any remaining assets not disposed as of 31 March 2026.

The table below presents the nonrecurring fair value measurements of these long-lived assets, categorized within the fair value hierarchy:

Balance Sheet Location	Total Estimated Value	Level 1	Level 2	Level 3
Assets held for sale	$454.7	$—	$—	$454.7
Plant and equipment, net	6.9	—	—	6.9

10. DEBT

U.S. Committed Credit Facilities

On 26 March 2026, we amended our existing 364-day $500 revolving credit agreement to extend its maturity date from 26 March 2026 to 25 March 2027. The amendment also provides that if we elect to convert the facility into a term loan, the maturity date of the term loan would be 25 March 2028. Fees incurred in connection with the amendment were not material.

We also maintain a five-year $3.0 billion revolving credit agreement that matures on 31 March 2029. Both the 364-day agreement and the five-year agreement are syndicated committed facilities that provide a source of liquidity and support our commercial paper program through the availability of senior unsecured debt to us and certain of our subsidiaries. No borrowings were outstanding under either of the agreements as of 31 March 2026 or 30 September 2025.

Repayments

During the first quarter of fiscal year 2026, we repaid at maturity $550.0 aggregate principal amount of our 1.50% senior notes due October 2025, plus accumulated and unpaid interest through the maturity date.

The amount of service costs capitalized in the first six months of fiscal years 2026 and 2025 were not material. The non-service related impacts are presented outside operating results within "Other non-operating income (expense), net."

For the six months ended 31 March 2026 and 2025, our cash contributions to funded pension plans and benefit payments under unfunded pension plans were $13.8 and $14.3, respectively. Total contributions for fiscal year 2026 are expected to be approximately $25 to $35. During fiscal year 2025, total contributions were $29.9.

During the three and six months ended 31 March 2026, we recognized actuarial loss amortization of $0.4 and $1.1 for our other postretirement benefits plans. During the three and six months ended 31 March 2025, we recognized actuarial gain amortization of $0.1 and $0.4 for our other postretirement benefits plans.

12. COMMITMENTS AND CONTINGENCIES

Litigation

We are involved in various legal proceedings, including commercial, competition, environmental, intellectual property, regulatory, product liability, and insurance matters. We do not currently believe there are any legal proceedings for which it is reasonably possible, individually or in the aggregate, to have a material impact on our financial condition, results of operations, or cash flows.

Environmental

In the normal course of business, we are involved in legal proceedings under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA," the federal Superfund law), the Resource Conservation and Recovery Act ("RCRA"), and similar state and foreign environmental laws relating to the designation of certain sites for investigation or remediation. Presently, there are 26 sites on which a final settlement or remediation has not been achieved where we, usually along with others, have been designated as a potentially responsible party by environmental authorities or are otherwise engaged in investigation or remediation, including cleanup activity at certain of our former and current manufacturing sites. We continually monitor these sites for which we have environmental exposure.

Accruals for environmental loss contingencies are recorded when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. As of 31 March 2026 and 30 September 2025, the consolidated balance sheets included accruals of $83.9 and $85.6, respectively, primarily as part of other noncurrent liabilities. These environmental liabilities will be paid over a period of up to 30 years. We estimate the exposure for environmental loss contingencies to range from $83 to a reasonably possible upper exposure of $97 as of 31 March 2026.

Actual costs to be incurred at identified sites in future periods may vary from the estimates, given inherent uncertainties in evaluating environmental exposures. Using reasonably possible alternative assumptions of the exposure level could result in an increase to the environmental accrual. Due to these inherent uncertainties, a significant increase to the reasonably possible upper exposure level could occur if a new site is designated, the scope of remediation is increased, a different remediation alternative is identified, or a significant increase in our proportionate share occurs. We do not expect that any sum we may have to pay in connection with environmental matters in excess of the amounts recorded or disclosed above would have a material adverse impact on our financial position or results of operations in any one year.

Pace

As of 31 March 2026, $53.1 of the environmental accrual was related to our facility in Pace, Florida.

In 2006, we sold our Amines business, which included operations at the Pace facility and recognized a liability for retained environmental obligations associated with remediation activities at the facility. We are required by the Florida Department of Environmental Protection ("FDEP") and the United States Environmental Protection Agency ("USEPA") to continue our remediation efforts. We recognized a before-tax expense of $42 in fiscal year 2006 in results from discontinued operations and recorded an environmental accrual of $42 in continuing operations on the consolidated balance sheets.

In the first quarter of 2015, we entered into a consent order with the FDEP requiring us to continue our remediation efforts at the Pace facility and complete a cost review every five years. In fiscal year 2020, we completed an updated cost review of the environmental remediation status at the Pace facility and increased our environmental accrual for this site by $19 in continuing operations on the consolidated balance sheet and recognized a before-tax expense of $19 in results from discontinued operations. In fiscal year 2024, we completed our most recent cost review of the environmental remediation status at the Pace facility. Based on our review, we expect ongoing activities to continue for 30 years. Additionally, we increased our estimate of near-term spending for an optimized groundwater recovery system and future annual costs due to higher inflation. As a result of these changes, we increased our environmental accrual for this site by $19 in continuing operations on the consolidated balance sheets and recognized a before-tax expense of $19 in results from discontinued operations in fiscal year 2024. There have been no significant changes to the estimated exposure.

33

We have implemented many of the remedial corrective measures at the Pace facility required under the 1995 consent orders issued by the FDEP and the USEPA. Contaminated soils have been bioremediated, and the treated soils have been secured in a lined on-site corrective action management unit. Several groundwater recovery systems have been installed to contain and remove contamination from groundwater. We completed an extensive assessment of the site to determine the efficacy of existing measures, what additional corrective measures may be needed, and whether newer remediation technologies that were not available in the 1990s might be better suited for groundwater remediation. Based on assessment results, we completed a focused feasibility study that identified alternative approaches that may more effectively remove contaminants. We continue to review alternative remedial approaches with the FDEP, and we completed additional field work during 2021 to support the design of an improved groundwater recovery network. This network targets areas of higher contaminant concentration and avoids areas of high groundwater iron which has proven to be a significant operability issue for the project. The design of the optimized recovery system was completed in fiscal year 2024, with construction expected to begin in fiscal year 2026. In the fourth quarter of fiscal year 2024, we completed an updated cost review which resulted in a change in assumptions regarding future operating costs as discussed above.

Piedmont

As of 31 March 2026, $9.8 of the environmental accrual was related to a production facility site in Piedmont, South Carolina.

On 30 June 2008, we sold our Elkton, Maryland, and Piedmont, South Carolina, production facilities and the related North American atmospheric emulsions and global pressure sensitive adhesives businesses. In connection with the sale, we recognized a liability for retained environmental obligations associated with remediation activities at the Piedmont site. This site is under active remediation for contamination caused by an insolvent prior owner.

We are required by the South Carolina Department of Environmental Services ("SCDES") to address both contaminated soil and groundwater. Numerous areas of soil contamination have been addressed, and contaminated groundwater is being recovered and treated. The SCDES issued its final approval to the site-wide feasibility study on 13 June 2017 and the Record of Decision for the site on 27 June 2018, after which we signed a Consent Agreement Amendment memorializing our obligations to complete the cleanup of the site.

Remediation has started in accordance with the design, which includes in-situ chemical oxidation treatment, as well as soil vapor extraction to remove volatile organic compounds from the unsaturated soils beneath the impacted areas of the plant. We estimate that source area remediation and groundwater recovery and treatment will continue through 2033. Thereafter, we currently expect this site to go into a state of monitored natural attenuation through 2038. We recognized a before-tax expense of $24 in 2008 as a component of income from discontinued operations and recorded an environmental liability of $24 in continuing operations on the consolidated balance sheets.

In the third quarter of fiscal year 2025, we completed an updated cost review of the environmental remediation status at Piedmont. Based on our review, we increased our estimate of remaining costs due to the extended period of time that will be required to complete the remediation along with higher annual costs due to inflation. As a result of these changes, we increased the environmental accrual for this site by $9 in continuing operations on the consolidated balance sheets and recognized a before-tax expense of $9 in results from discontinued operations.

34

Pasadena

As of 31 March 2026, $9.7 of the environmental accrual was related to a production facility site in Pasadena, Texas.

During fiscal year 2012, management committed to permanently shutting down our polyurethane intermediates production facility in Pasadena, Texas. In shutting down and dismantling the facility, we have undertaken certain obligations related to soil and groundwater contaminants. We have been pumping and treating groundwater to control off-site contaminant migration in compliance with regulatory requirements and under the approval of the Texas Commission on Environmental Quality ("TCEQ"). We estimate that the pump and treat system will continue to operate until 2042.

We continue to perform additional work to address other environmental obligations at the site. This additional work includes remediating impacted soils as required, maintaining recovery wells, continuing post closure care for two closed RCRA surface impoundment units, and maintaining engineering controls. Additionally, we have conducted an interim corrective action to treat impacted soils as recommended in the TCEQ 2019 Annual Report. We are currently in the process of renewing the site's RCRA permit. In 2012, we estimated the total exposure at this site to be $13. There have been no significant changes to the estimated exposure.

13. SHARE-BASED COMPENSATION

Our share-based compensation program includes performance and time-based deferred stock units. We issue shares from treasury stock upon the payout of deferred stock units. As of 31 March 2026, there were 0.6 million shares available for future grant under our Long-Term Incentive Plan ("LTIP"), which is shareholder approved.

Share-based compensation cost recognized on the consolidated income statements is summarized below:

	Three Months Ended		Six Months Ended
	31 March		31 March
	2026	2025	2026	2025
Before-tax share-based compensation cost(A)	$16.0	$38.3	$26.3	$54.8
Income tax benefit	(3.8)	(9.0)	(6.2)	(13.0)
After-tax share-based compensation cost	$12.2	$29.3	$20.1	$41.8

(A)Fiscal year 2025 includes noncash executive separation costs of $22.4 to accelerate vesting of share-based awards. Refer to the "Shareholder Activism-Related Costs" disclosure in Note 17, Supplemental Information, for additional information.

Before-tax share-based compensation cost is primarily included in "Selling and administrative expense" on our consolidated income statements. The amount of share-based compensation cost capitalized in the first six months of fiscal years 2026 and 2025 was not material.

35

Deferred Stock Units

During the six months ended 31 March 2026, we granted 100,048 performance shares to be earned over the performance period beginning 1 October 2025 and ending 30 September 2028.

The award conditions are equally weighted between market-based awards, which consider total shareholder return ("TSR") measured against a fixed group of companies that comprise the S&P 500 Industrials Index and the S&P Materials Index and awards that consider an internal performance measure for return on capital.

The fair value of the portion of the awards subject to the achievement of return on capital targets were valued based on the closing stock price of $260.86 on the grant date. The portion of the awards subject to market conditions were valued using a Monte Carlo simulation on the date of grant with an estimated grant-date fair value of $275.21 per unit. The model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the grant and calculates the fair value of the awards.

The calculation of the fair value of market-based deferred stock units used the following assumptions:

Expected volatility	34.5	%
Risk-free interest rate	3.6	%
Expected dividend yield	2.7	%

In addition, during the six months ended 31 March 2026, we granted 130,557 time-based deferred stock units at a weighted average grant-date fair value of $260.73.

We generally expense the grant-date fair value of these awards on a straight-line basis over the applicable vesting period. For the portion of performance shares subject to the achievement of return on capital, we consider the probability of meeting performance targets when recording compensation expense throughout the performance period.

16. INCOME TAXES

Effective Tax Rate

For the three and six months ended 31 March 2026, our consolidated income statements include an income tax expense of $158.7 and $318.1, respectively, compared to an income tax benefit of $505.8 and $365.1 for the comparative prior-year periods. The tax expenses in fiscal year 2026 represent an effective tax rate of 18.0% and 18.3% on the pre-tax income reported for the three and six months ended 31 March 2026, respectively. The tax benefits in fiscal year 2025 represented an effective tax rate of 22.5% and 25.1% on the pre-tax losses reported for the three and six months ended 31 March 2025, respectively. The fiscal year 2025 rates were primarily impacted by pre-tax charges of $2.9 billion for business and asset actions and other prior-year items as further discussed below.

Prior-Year Business and Asset Actions

In fiscal year 2025, we recorded charges related to our decision to exit certain projects and implement other cost-reduction measures as described in Note 4, Business and Asset Actions. These efforts resulted in pre-tax charges of approximately $2.9 billion during the second quarter of fiscal year 2025, which resulted in an overall loss from continuing operations before taxes for the three and six months ended 31 March 2025. The related net tax benefit of these actions, which primarily related to our U.S. operations, totaled $640.6.

The related net tax benefit of $640.6 recorded during the second quarter included a cost of $22.5 to establish reserves for uncertain tax positions related to the deductibility of certain costs in foreign subsidiaries as well as a cost of $13.1 primarily related to lower U.S. tax benefits for foreign-derived income. We also incurred a $41.8 increase in our valuation allowance related to tax benefits for foreign business and asset actions for which we could not recognize an income tax benefit.

Prior-Year Tax Reform Adjustment Related to Deemed Foreign Dividends

During the second quarter of fiscal year 2025, we recorded a net income tax benefit of $34.9 related to our intent to file a refund claim after a review of several U.S. Tax Court cases regarding the U.S. taxation of deemed foreign dividends in the transition year of the U.S. Tax Cuts and Jobs Act (our fiscal year 2018). While we were not a party to these cases, the opinions resulted in a change to our intent to pursue a refund claim. The $34.9 income tax benefit was net of a $67.8 reserve for an uncertain tax position related to the calculation of the refund amount.

38

Prior-Year Tax on Repatriation of Foreign Earnings

During the second quarter of fiscal year 2025, we recorded an income tax expense of $31.4 related to estimated withholding taxes on foreign earnings that we no longer intended to indefinitely reinvest.

Prior-Year Shareholder Activism-Related Costs

During the first six months of fiscal year 2025, we incurred costs of $61.3 related to a proxy contest led by an activist shareholder as further discussed in Note 17, Supplemental Information. The related net tax benefit recorded during the first half of fiscal year 2025 was $8.4.

Cash Paid for Taxes, Net of Refunds

Income tax payments, net of refunds, were $263.4 and $710.1 for the six months ended 31 March 2026 and 2025, respectively. Fiscal year 2025 included tax payments related to the sale of the LNG business.

17. SUPPLEMENTAL INFORMATION

Related Party Transactions

We have related party sales to some of our equity affiliates and joint venture partners as well as other income primarily from fees charged for use of Air Products' patents and technology. Sales to and other income from related parties totaled approximately $105 and $190 for the three and six months ended 31 March 2026, respectively, and $70 and $150 for the three and six months ended 31 March 2025, respectively. Sales agreements with related parties include terms that are consistent with those that we believe would have been negotiated at an arm’s length with an independent party. As of 31 March 2026 and 30 September 2025, our consolidated balance sheets included related party trade receivables of approximately $205 and $105, respectively.

Related party debt consists of shareholder loans with our joint venture partner, Lu’An Clean Energy Company. Total debt owed to related parties was $244.3 and $236.5 as of 31 March 2026 and 30 September 2025, respectively. These amounts included $61.0 and $59.0, respectively, in "Current portion of long-term debt" on the consolidated balance sheets.

Prior-Year Shareholder Activism-Related Costs

We recorded shareholder activism-related costs in fiscal year 2025 in connection with a proxy contest that concluded in January 2025 following certification of the election of directors at the 2025 Annual Meeting of Shareholders. Costs of $31.4 ($31.0 after tax) incurred during the second quarter of fiscal year 2025 primarily reflect executive separation costs for our former chief executive officer following the Board of Directors’ appointment of a new chief executive officer, which included a noncash expense of $22.4 related to the acceleration of vesting of share‑based awards and $7.3 in severance and other cash benefits. Costs of $61.3 ($52.9 after tax) incurred during the first six months of fiscal year 2025 also included legal and other professional service fees, as well as incremental proxy solicitation costs related to the 2025 Annual Meeting of Shareholders, which were largely incurred during the first quarter of fiscal year 2025.

Changes in Estimates

Changes in estimates on sale of equipment projects accounted for under the cost incurred input method are recognized as a cumulative adjustment for the inception-to-date effect of such change. We recorded changes to project revenue and cost estimates that unfavorably impacted operating income by approximately $25 and $58 for the three and six months ended 31 March 2026, respectively, and operating loss by approximately $15 and $45 for the three and six months ended 31 March 2025, respectively.

18. BUSINESS SEGMENT INFORMATION

We determine our reportable segments based on the manner in which our Chief Operating Decision Maker ("CODM") reviews financial results and allocates resources. The accounting policies applied to our reportable segments are consistent with those used in the preparation of our consolidated financial statements. Our reportable segments are as follows:

•Americas;

•Asia;

•Europe;

•Middle East and India; and

•Corporate and other.

The Americas, Asia, Europe, and Middle East and India segments represent the operations of our regional industrial gases business. Each of these segments qualifies as an individual operating segment and does not reflect the aggregation of multiple operating segments. Corporate and other consists of two operating segments that meet the aggregation criteria under GAAP. All segments also include our share of results from several equity method joint ventures.

Our CODM, who is our Chief Executive Officer, evaluates the performance of our reportable segments through segment operating income. This measure is reviewed regularly in internal management reports and serves as a key metric to monitor actual results against forecasts and prior periods. Segment operating income informs decisions related to resource allocation, including capital investments and employees, and supports strategic planning and long-term project development.

(A)Sales relate to external customers only. All intersegment sales are eliminated in consolidation.

(B)For the regional segments, other segment items primarily include impacts from transactions not directly related to our principal earnings activities, such as technology and royalty income and gains and losses on asset sales. For the Corporate and other segment, other segment items primarily include research and development expense and the net impact of gains and losses on foreign currency transactions.

(C)Operating income (loss) for our reportable segments does not include gains or losses that management does not consider to be indicative of underlying business performance, such as charges related to business and asset actions. Refer below for a reconciliation of total segment operating income to consolidated results.

(D)Segment equity affiliates’ income for the three and six months ended 31 March 2025 excludes a $6.8 impairment charge related to a joint venture in China, which was recorded as part of our business and asset actions during the second quarter of fiscal year 2025. As a result, total segment equity affiliates’ income does not reconcile to equity affiliates’ income for the total company as reported on the consolidated income statements for the three and six months ended 31 March 2025.

These forward-looking statements are based on management’s expectations and assumptions as of the date of this Quarterly Report on Form 10-Q and are not guarantees of future performance. Actual performance and financial results may differ materially from projections and estimates expressed in the forward-looking statements because of many factors not anticipated by management. These factors include, without limitation, those described in "Forward-Looking Statements" and Item 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended 30 September 2025 (the "2025 Form 10-K"), which was filed with the SEC on 20 November 2025, as well as in "Forward-Looking Statements" of this Quarterly Report on Form 10-Q.

This discussion should be read together with the accompanying interim consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q. Financial information is presented on a continuing operations basis. Unless otherwise stated, amounts are stated in millions of U.S. Dollars, except for per share data, which is calculated and presented on a diluted basis in U.S. Dollars per weighted-average common share.

The financial measures discussed below are presented in accordance with U.S. generally accepted accounting principles ("GAAP"), except as noted. We discuss certain financial measures on an "adjusted", or "non-GAAP", basis, which exclude gains or losses that management does not consider to be representative of our underlying business operations. These adjustments, which are described below for the periods presented, are not reflected in the results of our reportable segments. When viewed together with our GAAP results, we believe these non-GAAP financial measures offer a more complete understanding of the factors and trends affecting our financial performance and support analysis of our results on a more consistent basis. For each non-GAAP financial measure, including adjusted operating income, adjusted operating margin, adjusted earnings per share, the adjusted effective tax rate, and capital expenditures, we present a reconciliation to the most directly comparable financial measure calculated in accordance with GAAP. These reconciliations and further explanations of our use of non-GAAP financial measures are presented under the “Reconciliations of Non-GAAP Financial Measures” section beginning on page 62.

Comparisons included in the discussion that follows are for the second quarter and first six months of fiscal year 2026 versus ("vs.") the second quarter and first six months of fiscal year 2025. The disclosures provided in this Quarterly Report on Form 10-Q are complementary to those made in our 2025 Form 10-K.

We manage our operations, assess performance, and report earnings under five reportable segments: Americas, Asia, Europe, Middle East and India, and Corporate and other. Refer to Note 18, Business Segment Information, to the consolidated financial statements for additional information.

SECOND QUARTER 2026 VS. SECOND QUARTER 2025

SECOND QUARTER 2026 IN SUMMARY

•Sales of $3.2 billion increased 9%, or $255.6, due to higher volumes of 4%, a favorable impact from currency of 4%, and higher energy cost pass-through to customers of 2%, partially offset by lower pricing of 1% driven by lower helium pricing.

•Operating income of $752.7 increased 132%, or $3.1 billion, from an operating loss of $2.3 billion in the prior year, and operating margin improved to 23.7% from negative 79.8%, primarily due to prior-year charges for business and asset actions related to project exit decisions reached in the second quarter of fiscal year 2025.

•Adjusted operating income of $752.7 increased 19%, or $121.4, reflecting higher on-site volumes, favorable currency, and lower costs, partially offset by lower helium pricing. Adjusted operating margin improved to 23.7% from 21.6% in the prior year, primarily due to higher volumes and productivity, partially offset by energy cost pass-through to customers and pricing. These non-GAAP results exclude losses resulting from charges for business and asset actions as well as prior-year shareholder activism-related costs, as discussed below.

•Equity affiliates' income of $179.4 increased 23%, or $33.9, driven primarily by an affiliate in Mexico within the Americas segment.

•Earnings per share ("EPS") of $3.19 increased $10.96 from a loss per share of $7.77 in the prior year. On a non-GAAP basis, adjusted EPS of $3.20 increased $0.51 compared to $2.69 in the prior year. A summary table of changes in EPS is presented on page 45.

Sales

The table below summarizes the major factors that impacted consolidated sales for the periods presented:

Volume	4	%
Price	(1	%)
Energy cost pass-through to customers	2	%
Currency	4	%
Total Consolidated Sales Change	9	%

Sales of $3.2 billion increased 9%, or $255.6, due to higher volumes of 4%, a favorable currency impact of 4%, and higher energy cost pass-through to customers of 2%, partially offset by lower pricing of 1%. Volume growth was driven by on-sites, primarily HyCO in the Americas segment. The favorable currency impact reflected a weaker U.S. Dollar, most notably against the Euro, Chinese Renminbi, and British Pound Sterling. Lower pricing was primarily attributable to helium, partially offset by pricing improvements across non-helium product lines.

46

Cost of Sales and Gross Margin

Cost of sales of $2.2 billion increased 6%, or $130.5, due to an unfavorable currency impact of $81, higher energy cost pass-through to customers of $45, and higher costs of $19 related to sales volumes. These increases were partially offset by $8 of lower costs driven by productivity improvements and lower depreciation, which more than offset fixed-cost inflation and higher Americas maintenance costs, as well as $6 of lower product sourcing costs in our merchant business. Gross margin of 31.1% increased 150 bp from 29.6% in the prior year, driven by higher volumes.

Selling and Administrative Expense

Selling and administrative expense of $227.2 increased 2%, or $5.2, as unfavorable currency and labor inflation were partially offset by productivity improvements. Selling and administrative expense as a percentage of sales improved to 7.2% from 7.6% in the prior year.

Research and Development Expense

Research and development expense of $21.6 decreased 6%, or $1.3. Research and development expense as a percentage of sales decreased to 0.7% from 0.8% in the prior year.

Business and Asset Actions

We did not record any charges related to business and asset actions in the second quarter of fiscal year 2026.

Our consolidated prior year income statement for the three months ended 31 March 2025 included charges of $2.9 billion ($2.3 billion attributable to Air Products after tax, or $10.28 per share), consisting of initial charges related to project exit decisions as well as costs incurred in connection with our global cost reduction plan. These charges were not reflected in the results of our reportable segments. For additional information, refer to Note 4, Business and Asset Actions, to the consolidated financial statements.

Prior Year Shareholder Activism-Related Costs

We recorded shareholder activism-related costs in fiscal year 2025 in connection with a proxy contest that concluded in January 2025 following certification of the election of directors at the 2025 Annual Meeting of Shareholders. Costs of $31.4 ($31.0 after tax, or $0.14 per share) incurred during the second quarter were primarily for executive separation costs for our former chief executive officer. These costs were not reflected in the results of our reportable segments. For additional information, refer to Note 17, Supplemental Information, to the consolidated financial statements.

Other Income (Expense), Net

Other income of $14.1 increased 1%, or $0.2.

Operating Income (Loss) and Operating Margin

Operating income of $752.7 increased 132%, or $3.1 billion, from an operating loss of $2.3 billion in the prior year. The fiscal year 2025 loss was driven by $2.9 billion of charges for business and asset actions, largely related to project exit decisions reached in the second quarter of fiscal year 2025, and also included $31 of shareholder activism‑related costs. Volume impacts were favorable by $94, driven by on-sites. Currency was favorable by $25, and costs were lower by $13, as productivity improvements and lower depreciation more than offset fixed-cost inflation and higher Americas maintenance costs. These factors were partially offset by lower pricing, net of power costs, of $11, driven by lower helium pricing. Lower helium pricing was partially mitigated by pricing improvements across non-helium product lines. Operating margin was 23.7% compared to negative 79.8% in the prior year, which was primarily attributable to the charges for business and asset actions in fiscal year 2025.

On a non-GAAP basis, which excludes the charges for business and asset actions and prior-year shareholder activism-related costs discussed above, adjusted operating income of $752.7 increased 19%, or $121.4, due to higher volumes, favorable currency, and lower costs, partially offset by lower pricing. Adjusted operating margin improved to 23.7% from 21.6% in the prior year, primarily due to higher volumes and productivity, partially offset by energy cost pass-through to customers and pricing.

Equity Affiliates' Income

Equity affiliates' income of $179.4 increased 23%, or $33.9, primarily driven by an affiliate in Mexico within the Americas segment. Additionally, the prior year included a project exit-related impairment charge of $6.8 related to a joint venture in China.

47

Interest Expense

	Three Months Ended
	31 March
	2026	2025
Interest incurred	$167.5	$145.8
Less: Capitalized interest	118.0	103.6
Interest expense	$49.5	$42.2

Interest expense increased 17%, or $7.3, driven by higher interest on principal borrowings from Euro- and U.S. Dollar-denominated senior fixed-rate notes issued in fiscal year 2025.

Other Non-Operating Income (Expense), Net

Other non-operating income of $0.9 increased $19.5 compared to an expense of $18.6 in the prior year. The prior year included an expense of $11.5 ($3.0 attributable to Air Products after tax, or $0.01 per share) on certain interest rate swaps held by the NEOM Green Hydrogen Company joint venture. As of 1 January 2026, all swaps were re‑designated as cash flow hedges. Refer to Note 3, Variable Interest Entities, and Note 8, Financial Instruments, to the consolidated financial statements for additional information.

The increase also reflects income from excluded components from the assessment of effectiveness of our derivatives and lower non-service pension costs, partially offset by lower interest income on short-term investments.    

Effective Tax Rate

The effective tax rate equals the income tax expense (benefit) divided by income or loss before taxes. Equity affiliates' income is primarily included net of income taxes within income or loss before taxes on our consolidated income statements.

For the three months ended 31 March 2026, our consolidated income statement includes an income tax expense of $158.7 compared to an income tax benefit of $505.8 in the prior year period. The tax expense in fiscal year 2026 represents an effective tax rate of 18.0% on the pre-tax income of $883.5 reported for the three months ended 31 March 2026. The tax benefit in fiscal year 2025 represented an effective rate of 22.5% on the pre-tax loss of $2.2 billion reported for the three months ended 31 March 2025.

The prior-year rate was primarily impacted by $2.9 billion of pre-tax charges for business and asset actions and other items as further discussed in Note 16, Income Taxes. Also contributing to a lower rate for the current fiscal year were higher foreign and domestic tax credits and incentives and higher equity affiliates' income. These items were partially offset by a higher cost of U.S. tax on foreign earnings and withholding taxes on foreign earnings we no longer intend to indefinitely reinvest.

Our adjusted effective tax rate, which excludes the impact of adjustments presented in the "Reconciliations of Non-GAAP Financial Measures" section beginning on page 62, was 18.0% and 19.1% for the three months ended 31 March 2026 and 2025, respectively.

Equity affiliates’ income	$55.8		$31.2		$24.6	79	%

The table below summarizes the major factors that impacted sales in the Americas segment for the periods presented:

Volume	3	%
Price	—	%
Energy cost pass-through to customers	4	%
Currency	1	%
Total Americas Sales Change	8	%

Sales of $1.4 billion increased 8%, or $96.7, due to higher energy cost pass-through to customers of 4%, higher volumes of 3%, and favorable currency of 1%. The higher energy cost pass-through reflects increased natural gas rates in the U.S. Gulf Coast. Volumes were favorable in both on-sites and merchant, including helium, partially offset by income from a favorable one-time customer contract amendment in the prior year.

Operating income of $373.9 increased 2%, or $8.2, as higher volumes of $15 and favorable currency of $3 were partially offset by higher costs of $6 and lower pricing, net of power costs, of $4. The lower pricing reflected lower helium pricing and higher power costs in our merchant business, which were partially mitigated by favorable pricing actions across non-helium product lines. The increase in costs was primarily due to maintenance turnarounds and fixed-cost inflation, partially offset by lower depreciation. Operating margin of 27.0% decreased 140 bp from 28.4% in the prior year driven by a headwind of approximately 100 bp from higher energy cost pass-through to our on-site customers.

Equity affiliates’ income of $55.8 increased 79%, or $24.6, driven primarily by an affiliate in Mexico.

Equity affiliates’ income	$11.7		$10.5		$1.2	11	%

The table below summarizes the major factors that impacted sales in the Asia segment for the periods presented:

Volume	4	%
Price	(1	%)
Energy cost pass-through to customers	1	%
Currency	4	%
Total Asia Sales Change	8	%

Sales of $832.6 increased 8%, or $58.5, due to higher volumes of 4% primarily related to on-site activity, including new assets, and improved helium, as well as favorable currency of 4% driven by the weakening of the U.S. Dollar against the Chinese Renminbi. Higher energy cost pass-through to customers contributed 1%, offset by lower pricing of 1%. The 1% total segment price decrease equates to a 5% decline in our merchant business, driven by lower helium pricing.

Operating income of $240.0 increased 25%, or $48.6, due to higher volumes of $34, lower costs of $16 driven by productivity, and favorable currency of $8, partially offset by lower pricing, net of power costs, of $10. Depreciation was lower in fiscal year 2026 primarily due to certain gasification assets being classified as held for sale. Operating margin of 28.8% increased 410 bp from 24.7% in the prior year, primarily due to the impact of higher volumes and favorable costs, partially offset by lower pricing.

Equity affiliates’ income of $11.7 increased 11%, or $1.2, driven primarily by an affiliate in Thailand.

Volume	2	%
Price	(1	%)
Energy cost pass-through to customers	(2	%)
Currency	9	%
Total Europe Sales Change	8	%

Sales of $789.0 increased 8%, or $61.6, as favorable currency of 9% and higher volumes of 2% were partially offset by lower energy cost pass-through to customers of 2% and lower pricing of 1%. Favorable currency primarily reflected the weakening of the U.S. Dollar against the Euro and British Pound Sterling. Higher volumes were driven by on-sites, including the impact of a prior-year turnaround, partially offset by lower helium. Energy cost pass-through declined due to lower natural gas rates. Lower helium pricing was partially mitigated by favorable pricing actions across non-helium product lines.

Operating income of $211.6 increased 8%, or $16.1, due to higher volumes of $16, favorable currency of $16, and higher pricing, net of lower power costs, of $4, partially offset by higher costs of $20. The increase in costs was primarily due to higher depreciation and fixed-cost inflation. Operating margin of 26.8% decreased 10 bp from 26.9% in the prior year.

Equity affiliates’ income of $31.9 increased 15%, or $4.2, driven primarily by an affiliate in Italy.

Sales of $29.2 decreased 11%, or $3.6, primarily due to lower volumes. Operating income was $4.6 compared to a loss of $2.9 in the prior year, reflecting lower costs, including productivity improvements and the impact of the deconsolidation of Blue Hydrogen Industrial Gases Company ("BHIG") in the second quarter of fiscal year 2025.

Sales

The table below summarizes the major factors that impacted consolidated sales for the periods presented:

Volume	2	%
Price	—	%
Energy cost pass-through to customers	2	%
Currency	3	%
Total Consolidated Sales Change	7	%

Sales of $6.3 billion increased 7%, or $426.6, due to a favorable currency impact of 3%, higher volumes of 2%, and higher energy cost pass-through to customers of 2%. Currency was favorable as the U.S. Dollar weakened, most notably against the Euro. Volume growth was driven by on-sites, primarily from new assets and Americas HyCO facilities, partially offset by lower helium demand and a significant, non-recurring helium sale to an existing merchant customer in the Americas segment in the prior year. Pricing was flat as improvement across non-helium product lines was offset by lower helium pricing.

55

Cost of Sales and Gross Margin

Cost of sales of $4.3 billion increased 5%, or $221.5, due to an unfavorable currency impact of $128 and higher energy cost pass-through to customers of $124. These increases were partially offset by $16 of lower costs driven by productivity improvements and reduced depreciation, which more than offset fixed-cost inflation, lower product sourcing costs of $9, and lower costs of $5 related to sales volumes. Gross margin of 31.6% increased 120 bp from 30.4% in the prior year as the benefits from higher volumes were partially offset by higher energy cost pass-through to customers.

Selling and Administrative Expense

Selling and administrative expense of $455.9 decreased 2%, or $8.5, as productivity improvements were partially offset by unfavorable currency and fixed-cost inflation. Selling and administrative expense as a percentage of sales improved to 7.3% from 7.9% in the prior year.

Research and Development Expense

Research and development expense of $42.0 decreased 6%, or $2.9. Research and development expense as a percentage of sales decreased to 0.7% from 0.8% in the prior year.

Business and Asset Actions

Our consolidated income statement for the six months ended 31 March 2026 included charges of $28.3 ($24.6 attributable to Air Products after tax, or $0.11 per share), related to project exit decisions reached in fiscal year 2025. Our consolidated prior-year income statement for the six months ended 31 March 2025 included charges of $2.9 billion ($2.3 billion attributable to Air Products after tax, or $10.28 per share), consisting of initial charges related to these decisions as well as costs incurred in connection with our global cost reduction plan. These charges were not reflected in results of our reportable segments. For additional information, refer to Note 4, Business and Asset Actions, to the consolidated financial statements.

Prior-Year Shareholder Activism-Related Costs

We recorded shareholder activism-related costs in fiscal year 2025 in connection with a proxy contest that concluded in January 2025 following certification of the election of directors at the 2025 Annual Meeting of Shareholders. Costs of $61.3 ($52.9 after tax, or $0.24 per share) incurred during the first six months of fiscal year 2025 included executive separation costs for our former chief executive officer, professional service fees, and incremental proxy solicitation costs related to the 2025 Annual Meeting of Shareholders. These costs were not reflected in the results of our reportable segments. For additional information, refer to Note 17, Supplemental Information, to the consolidated financial statements.

Other Income (Expense), Net

Other income of $24.7 decreased 33%, or $12.1, primarily due to the prior year sale of a U.S. equity method investment.

Operating Income (Loss) and Operating Margin

Operating income of $1.5 billion increased 188%, or $3.2 billion, from an operating loss of $1.7 billion in the prior year. The fiscal year 2025 loss was driven by $2.9 billion of charges for business and asset actions, largely related to project exit decisions reached in the second quarter of fiscal year 2025, and also included $61 of shareholder activism‑related costs. Volume impacts were favorable by $121 driven by on-sites, partially offset by lower helium. Currency was favorable by $38, and costs were lower by $35, as productivity improvements and lower depreciation were partially offset by fixed-cost inflation. Pricing, net of power costs, improved by $11 driven by non-helium merchant products. Operating margin was 23.7% compared to negative 28.8% in the prior year, which was primarily attributable to the charge for business and asset actions in fiscal year 2025.

On a non-GAAP basis, which excludes the charges for business and asset actions and prior year-shareholder activism-related costs discussed above, adjusted operating income of $1.5 billion increased 16%, or $204.4 due to higher volumes, favorable currency, lower costs, and higher pricing, net of power costs. Adjusted operating margin improved to 24.1% from 22.3% in the prior year, primarily due to higher volumes and productivity, partially offset by energy cost pass-through to customers.

Equity Affiliates' Income

Equity affiliates' income of $351.6 increased 19%, or $55.5, driven by an affiliate in Mexico within the Americas segment. Additionally, the prior year included a project exit-related impairment charge of $6.8 related to a joint venture in China.

Interest Expense

	Six Months Ended

	2026	2025
Interest incurred	$335.3	$285.7
Less: Capitalized interest	231.5	200.9
Interest expense	$104.0	$84.8

Interest expense increased 23%, or $19.2, driven by higher interest on principal borrowings from Euro- and U.S. Dollar-denominated senior fixed-rate notes issued in fiscal year 2025.

Other Non-Operating Income (Expense), net

Other non-operating expense of $0.5 decreased $20.8 from income of $20.3 in the prior year. The prior year included a gain of $27.3 ($7.3 attributable to Air Products after tax, or $0.03 per share) on certain interest rate swaps held by the NEOM Green Hydrogen Company joint venture. As of 1 January 2026, all swaps were re‑designated as cash flow hedges. Refer to Note 3, Variable Interest Entities, and Note 8, Financial Instruments, to the consolidated financial statements for additional information. We also recognized lower interest income on short-term investments in fiscal year 2026.

These impacts were partially offset by income from excluded components from the assessment of effectiveness of our derivatives and lower non-service pension costs.

Effective Tax Rate

The effective tax rate equals the income tax expense (benefit) divided by income or loss before taxes. Equity affiliates' income is primarily included net of income taxes within income or loss before taxes on our consolidated income statements.

For the six months ended 31 March 2026, our consolidated income statement includes an income tax expense of $318.1 compared to an income tax benefit of $365.1 in the prior year period. The tax expense in fiscal year 2026 represents an effective tax rate of 18.3% on the pre-tax income of $1.7 billion reported for the six months ended 31 March 2026. The tax benefit in fiscal year 2025 represented an effective rate of 25.1% on the pre-tax loss of $1.5 billion reported for the six months ended 31 March 2025.

The prior-year rate was primarily impacted by $2.9 billion of pre-tax charges for business and asset actions and other items as further discussed in Note 16, Income Taxes. Also contributing to a lower rate for the current fiscal year were higher foreign and domestic tax credits and incentives and higher equity affiliates' income. These items were partially offset by a higher cost of U.S. tax on foreign earnings, larger excess tax benefits on share-based compensation in the prior year, and a benefit from a U.S. state tax law change in the prior period.

Our adjusted effective tax rate, which excludes the impact of adjustments presented in the "Reconciliations of Non-GAAP Financial Measures" section beginning on page 62, was 18.3% and 18.9% for the six months ended 31 March 2026 and 2025, respectively.

Discussion of First Six Months Results by Business Segment

Americas

	Six Months Ended
	31 March				Change vs. Prior Year
	2026		2025		$	%/bp
Sales	$2,725.6		$2,574.8		$150.8	6	%
Operating income	777.7		753.9		23.8	3	%
Operating margin	28.5	%	29.3	%		(80	bp)
Equity affiliates’ income	$107.5		$66.3		$41.2	62	%

The table below summarizes the major factors that impacted sales in the Americas segment for the periods presented:

Volume	(1	%)
Price	1	%
Energy cost pass-through to customers	5	%
Currency	1	%
Total Americas Sales Change	6	%

Sales of $2.7 billion increased 6%, or $150.8, due to higher energy cost pass-through to customers of 5%, higher pricing of 1%, and a favorable currency impact of 1%, partially offset by lower volumes of 1%. Higher energy cost pass-through reflects increased natural gas rates in the U.S. Gulf Coast. The 1% total segment price increase equates to a 2% improvement in our merchant business, driven by non-helium product lines. The modest volume decline was primarily due to favorable non‑recurring items in the prior year, including a significant helium sale to an existing merchant customer and a one‑time customer contract amendment, partially offset by higher on‑site volumes in fiscal year 2026.

Operating income of $777.7 increased 3%, or $23.8, as favorable business mix of $18, positive pricing, net of higher power costs, of $12, and favorable currency of $4 were partially offset by higher costs of $10. The increase in costs was primarily due to fixed-cost inflation and prior‑year income from the sale of an equity method investment, partially offset by lower depreciation. Operating margin of 28.5% decreased 80 bp from 29.3% as a headwind of approximately 150 basis points from higher energy cost pass‑through to customers was partially offset by favorable business mix.

Equity affiliates’ income of $107.5 increased 62%, or $41.2, driven by an affiliate in Mexico.

Operating margin	28.4	%	25.6	%		280	bp
Equity affiliates’ income	$25.5		$20.8		$4.7	23	%

The table below summarizes the major factors that impacted sales in the Asia segment for the periods presented:

Volume	2	%
Price	(2	%)
Energy cost pass-through to customers	2	%
Currency	3	%
Total Asia Sales Change	5	%

Sales of $1.7 billion increased 5%, or $72.9, as a favorable currency impact of 3%, higher volumes of 2%, and higher energy cost pass-through to customers of 2% were partially offset by lower pricing of 2%. Favorable currency reflected the weakening of the U.S. dollar against the Chinese Renminbi, while higher volumes were attributable to on‑sites, including contributions from new assets. The total segment pricing decline of 2% equates to a 4% decline in our merchant business, driven by lower helium pricing.

Operating income of $472.3 increased 16%, or $64.5, due to higher volumes of $41, lower costs of $31 driven by productivity, and a favorable currency impact of $12, partially offset by lower pricing, net of power costs, of $20. Depreciation was lower in fiscal year 2026 primarily due to certain gasification assets being classified as held for sale. Operating margin of 28.4% increased 280 bp from 25.6% in the prior year, primarily due to the impact of higher volumes and favorable costs, partially offset by lower pricing.

Equity affiliates’ income of $25.5 increased 23%, or $4.7, driven by affiliates in China and Thailand.

Volume	3	%
Price	—	%
Energy cost pass-through to customers	(2	%)
Currency	9	%
Total Europe Sales Change	10	%

Sales of $1.6 billion increased 10%, or $146.4, due to a favorable impact from currency of 9% and higher volumes of 3%, partially offset by lower energy cost pass-through to customers of 2%, primarily due to lower natural gas rates. Favorable currency primarily reflected the weakening of the U.S. Dollar against the Euro. The higher volumes were driven by on-sites, including the impact of a prior-year turnaround, partially offset by lower helium. Pricing was flat as improvement across non-helium product lines was offset by lower helium pricing.

Operating income of $435.1 increased 14%, or $53.1, due to higher volumes of $37, favorable currency of $27, higher pricing, net of lower power costs, of $19, partially offset by higher costs of $30. The increase in costs was primarily due to higher depreciation and fixed-cost inflation. Operating margin of 27.7% increased 90 bp from 26.8% in the prior year as the benefits from higher volumes and pricing were partially offset by higher costs.

Equity affiliates’ income of $55.3 increased 20%, or $9.4, driven by an affiliate in Italy.

RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES

We present certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles ("GAAP") because they exclude items that management does not consider to be representative of our underlying business operations. We provide these adjusted non-GAAP financial measures to allow investors, potential investors, securities analysts, and others to evaluate our business in the same manner as management. When viewed together with our GAAP results, we believe these non-GAAP financial measures offer a more complete understanding of the factors and trends affecting our financial performance and support analysis of our results on a more consistent basis.

Readers are cautioned that non‑GAAP financial measures have inherent limitations and should not be considered in isolation or as a substitute for the corresponding GAAP measures. Our definitions and calculations of non‑GAAP financial measures may differ from those used by other companies, which may limit comparability.

Non-GAAP Performance Measures

Management uses non-GAAP performance measures, including adjusted operating income, adjusted operating margin, and adjusted earnings per share ("EPS"), to assess our performance because these measures exclude items that management does not consider to be representative of our underlying business operations. In addition, adjusted operating income and adjusted EPS are important components of our incentive compensation plans. We also use adjusted operating margin to assess operational efficiency, cost discipline, and overall profitability.

Our non‑GAAP performance measures are adjusted to exclude gains or losses that management believes are not associated with the ongoing operations of our business. These adjustments, which are described below for the periods presented, are not reflected in the results of our reportable segments. Although these items are often difficult to predict, readers should be aware that similar gains or losses may occur in future periods. The related tax effects reflect the expected current and deferred income tax impacts of our non-GAAP adjustments, which are primarily driven by the statutory tax rates of the applicable jurisdictions and the taxability of the underlying adjustments in those jurisdictions.

We reconcile each non‑GAAP performance measure to its most directly comparable GAAP measure in the table below, followed by descriptions of each non-GAAP adjustment. Margins are calculated by dividing the applicable line item by consolidated sales for the relevant period. In addition to our non-GAAP performance measures, we also present components used in calculating adjusted EPS to illustrate the per share effect of our non‑GAAP adjustments. All per share amounts are calculated on a diluted basis from continuing operations attributable to Air Products. Because margins and per share amounts are calculated independently, the individual components may not sum to the related totals due to rounding.

Non-GAAP Adjustments

Business and Asset Actions

In the first half of fiscal year 2026, we recorded charges of $28.3 ($24.6 after tax, or $0.11 per share) related to project exit decisions reached in fiscal year 2025. Of these charges, $22.0 were recorded to operating income to update cost estimates as we settle project‑related commitments and dispose of associated assets, and $6.3 was recorded in "Other non‑operating income (expense), net" for losses on cross‑currency interest rate swaps terminated in connection with the early repayment of related intercompany loans for one of the affected gasification projects in China. No additional charges were recorded during the second quarter of fiscal year 2026.

Initial charges related to these project exit decisions were recorded together with costs associated with our global cost reduction plan during the second quarter of fiscal year 2025 and totaled $2.9 billion ($2.3 billion attributable to Air Products after tax, or $10.28 per share). These charges included $6.8 that was recorded in equity affiliates' income related to an other-than-temporary impairment of a joint venture in China formed to develop clean hydrogen infrastructure in the region.

For additional information regarding business and asset actions, refer to Note 4, Business and Asset Actions, to the consolidated financial statements.

Estimates related to business and asset actions reflect our best judgment based on information available at the time the charges were recorded. Final settlement of these items may differ materially from current estimates, which could impact our consolidated financial statements in future periods.

Prior-Year Shareholder Activism-Related Costs

We recorded shareholder activism-related costs in fiscal year 2025 in connection with a proxy contest that concluded in January 2025 following certification of the election of directors at the 2025 Annual Meeting of Shareholders. Costs of $31.4 ($31.0 after tax, or $0.14 per share) incurred during the second quarter of fiscal year 2025 primarily reflected executive separation costs for our former chief executive officer following the Board of Directors’ appointment of a new chief executive officer, which included a noncash expense of $22.4 related to the acceleration of vesting of share‑based awards and $7.3 in severance and other cash benefits. Costs of $61.3 ($52.9 after tax, or $0.24 per share) incurred during the first six months of fiscal year 2025 also included legal and other professional service fees, as well as incremental proxy solicitation costs related to the 2025 Annual Meeting of Shareholders, which were largely incurred during the first quarter of fiscal year 2025.

Prior-Year Gain on De-designation of Cash Flow Hedges

In fiscal year 2024, we discontinued cash flow hedge accounting for certain interest rate swaps due to changes in the anticipated drawdown timeline for hedged borrowings related to the NEOM Green Hydrogen Project. These swaps are held by NEOM Green Hydrogen Company, a consolidated joint venture accounted for under the variable interest model, in which Air Products holds a one-third ownership interest. As a result of the de-designation, unrealized gains and losses related to the affected swaps were recorded in "Other non-operating income (expense), net" on our consolidated income statements. During the second quarter of fiscal year 2025, we recorded an unrealized loss of $11.5 ($3.0 attributable to Air Products after tax, or $0.01 per share), with $7.5 attributable to our noncontrolling partners. For the six months ended 31 March 2025, the total amount recorded was a net unrealized gain of $27.3 ($7.3 attributable to Air Products after tax, or $0.03 per share), with $17.7 attributable to our noncontrolling partners, respectively.

We re-designated the affected swaps as cash flow hedges when the outstanding borrowings under the available project financing became commensurate with the swaps’ notional values. As of 1 January 2026, all swaps were re-designated as cash flow hedges. The unrealized gain on swaps that remained de-designated during the first quarter of fiscal year 2026 was not material.

Non-Service Related Pension Items

Non-service related pension items resulted in net non-operating costs of $4.6 ($3.5 after tax, or $0.02 per share) and $8.0 ($6.0 after tax, or $0.03 per share) for the three and six months ended 31 March 2026, respectively, compared to $10.7 ($8.0 after tax, or $0.04 per share) and $21.2 ($15.9 after tax, or $0.07 per share) for the three and six months ended 31 March 2025, respectively. Non-service related components are recurring, non-operating items that include interest cost, expected returns on plan assets, prior service cost amortization, actuarial loss amortization, as well as special termination benefits, curtailments, and settlements. The net impact of non-service related components is reflected within “Other non-operating income (expense), net” on our consolidated income statements. Adjusting for the impact of non-service pension components provides management and users of our financial statements with a more accurate representation of our underlying business performance because these components are driven by factors that are unrelated to our operations, such as volatility in equity and debt markets. Further, non-service related components are not indicative of our defined benefit plans’ future contribution needs due to the funded status of the plans.

Prior-Year Tax Reform Adjustment Related to Deemed Foreign Dividends

During the second quarter of fiscal year 2025, we recorded a net income tax benefit of $34.9 ($0.16 per share) related to our intent to file a refund claim after a review of several U.S. Tax Court cases regarding the U.S. taxation of deemed foreign dividends in the transition year of the U.S. Tax Cuts and Jobs Act (our fiscal year 2018). While we were not a party to these cases, the opinions resulted in a change to our intent to pursue a refund claim.

Prior-Year Tax on Repatriation of Foreign Earnings

During the second quarter of fiscal year 2025, we recorded an income tax expense of $31.4 ($0.14 per share) related to estimated withholding taxes on foreign earnings that we no longer intended to indefinitely reinvest.

ADJUSTED EFFECTIVE TAX RATE

The effective tax rate represents income tax expense (benefit) divided by income or loss before taxes as reported under GAAP. We calculate our adjusted effective tax rate by adjusting both the numerator and the denominator to exclude the tax and pre‑tax effects of our non‑GAAP adjustments, respectively.

The table below presents a reconciliation of the GAAP effective tax rate to our adjusted effective tax rate:

	Three Months Ended 31 March				Six Months Ended 31 March

CAPITAL EXPENDITURES (NON-GAAP)

Capital expenditures is a non-GAAP financial measure that management uses to evaluate our deployment of capital and assess alignment with our strategic priorities. Our calculation of this measure begins as the sum of cash paid for additions to plant and equipment, including long-term deposits, acquisitions (less cash acquired), investment in and advances to unconsolidated affiliates, and investment in financing receivables, each of which are reported on our consolidated statements of cash flows.

We then adjust this amount to exclude spending for additions to plant and equipment by our consolidated joint venture, NEOM Green Hydrogen Company (“NGHC”), to the extent such spending is funded by sources other than Air Products’ cash. These other funding sources include NGHC’s project financing, which is non‑recourse to Air Products, as well as equity contributions from the other joint venture partners. Management believes this adjustment provides a more useful view of the capital we deploy to support the ongoing growth of our business.

The most directly comparable GAAP measure to our non‑GAAP capital expenditures is “Cash used for investing activities,” as reported on our consolidated statements of cash flows. The reconciliation of cash used for investing activities to our reported capital expenditures is provided below:

	Six Months Ended

NGHC expenditures not funded by Air Products' equity(A)	(590.4)	(1,470.9)
Capital expenditures	$1,788.4	$2,939.4

(A)Reflects the portion of "Additions to plant and equipment, including long-term deposits" that is associated with NGHC, less our approximate cash investment in the joint venture. Substantially all the funding we provide to NGHC is limited for use by the joint venture for its capital expenditures.

67

LIQUIDITY AND CAPITAL RESOURCES

We believe we have sufficient cash, cash flows from operations, and access to funding sources to meet our liquidity needs. As further discussed in the "Cash Flows From Financing Activities" section below, we are able to raise capital through a variety of financing activities, including accessing capital or commercial paper markets or drawing upon our credit facilities.

As of 31 March 2026, we held cash and cash items of $951.0, substantially all of which were held outside the U.S. We do not expect a significant portion of the earnings from our foreign subsidiaries and affiliates to be subject to U.S. income tax upon repatriation. Depending on the country in which these entities operate, repatriation of earnings may be subject to foreign withholding and other taxes. However, we intend to indefinitely reinvest the majority of our foreign cash and cash items that would be subject to additional taxes outside the U.S.

Changes in working capital accounts	(271.3)	(703.5)
Cash Provided by Operating Activities	$2,004.4	$1,139.8

For the first six months of fiscal year 2026, cash provided by operating activities was $2.0 billion. The adjustment for deferred income taxes of $125.6 primarily reflects the timing of tax deductions associated with prior-year charges for business and asset actions. For additional information, refer to Note 4, Business and Asset Actions, to the consolidated financial statements. The working capital accounts were a net use of cash of $271.3, primarily driven by a $246.4 use related to payables and accrued liabilities. This use primarily included payments for incentive compensation under the fiscal year 2025 plan, contract terminations tied to our business and asset actions, and previously accrued severance actions under our global cost reduction plan.

For the first six months of fiscal year 2025, cash provided by operating activities was $1.1 billion. The adjustment for deferred income taxes of $540.1 was primarily driven by the tax impacts of charges recorded for business and asset actions in the second quarter of fiscal year 2025 as discussed in Note 4, Business and Asset Actions, to the consolidated financial statements. Other adjustments of $87.8 primarily included adjustments for noncash currency impacts of intercompany balances. The working capital accounts were a use of cash of $703.5, which was primarily driven by a use of cash of $571.0 within "Other working capital". Further, "Other working capital" included income tax payments in excess of expense of $515.4, which was driven by payments of $395 related to the gain on the sale of the LNG business in September 2024. The use of cash of $66.9 within "Trade receivables", primarily related to the timing of cash collections.

Cash Used for Investing Activities	($2,318.8)	($4,419.4)

For the first six months of fiscal year 2026, cash used for investing activities of $2.3 billion was primarily driven by additions to plant and equipment, including long-term deposits, as discussed in the "Capital Expenditures" section below.

For the first six months of fiscal year 2025, cash used for investing activities was $4.4 billion. The use of cash primarily resulted from additions to plant and equipment, including long-term deposits, of $4.0 billion. Refer to the "Capital Expenditures" section below for further detail. Investments in and advances to unconsolidated affiliates resulted in a use of cash of $365.4. Purchases of investments of $117.6 included purchases of time deposits, which have terms greater than three months but less than one year, and exceeded proceeds from investments of $11.1.

Capital Expenditures (Non-GAAP Financial Measure)

The components of our capital expenditures are detailed in the table below. Refer to page 67 for a definition of this non-GAAP financial measure as well as a reconciliation to cash used for investing activities.

NGHC expenditures not funded by Air Products' equity(A)	(590.4)	(1,470.9)
Capital expenditures	$1,788.4	$2,939.4

(A)Reflects the portion of "Additions to plant and equipment, including long-term deposits" that is associated with NGHC, less our approximate cash investment in the joint venture. Substantially all the funding we provide to NGHC is limited for use by the joint venture for its capital expenditures. For additional information regarding this adjustment, refer to page 67.

Capital expenditures for the first six months of fiscal year 2026 totaled $1.8 billion compared to $2.9 billion in the prior year. Cash outflows for both periods primarily reflect investments in clean energy initiatives, including the NEOM Green Hydrogen Project and clean energy complexes in Louisiana, United States, and Alberta, Canada, as well as ongoing capital spending to maintain and replace assets in our core industrial gases business. Spending on the NEOM Green Hydrogen Project declined in fiscal year 2026 as the project nears completion.

69

Outlook for Investing Activities

It is not possible, without unreasonable efforts, to reconcile our forecasted capital expenditures to future cash used for investing activities because management is unable to identify the timing or occurrence of our future investment activity, which is driven by our assessment of competing opportunities at the time we enter into transactions. These decisions, either individually or in the aggregate, could have a significant effect on our cash used for investing activities. Accordingly, management is unable to fully reconcile, without unreasonable efforts, our forecasted capital expenditures to future cash used for investing activities.

We expect capital expenditures for fiscal year 2026 to be approximately $4.0 billion, reflecting continued investment in our energy transition projects, traditional industrial gas projects, and maintenance within our core business. Approximately $1 billion of this amount is expected to be dedicated to traditional industrial gas projects. We anticipate funding these expenditures through our existing cash balance and cash generated from continuing operations. We also have access to capital and money market financing as well as other sources of funding as discussed in the "Financing and Capital Structure" section below.

Cash Flows From Financing Activities

	Six Months Ended
	31 March
	2026	2025
Long-term debt proceeds	$439.2	$2,002.5
Payments on long-term debt	(588.7)	(332.3)
Net increase in commercial paper and short-term borrowings	269.7	645.6
Dividends paid to shareholders	(797.0)	(787.4)
Investments by noncontrolling interests	120.5	355.7
Other financing activities	(34.8)	(59.0)
Cash (Used for) Provided by Financing Activities	($591.1)	$1,825.1

For the first six months of fiscal year 2026, cash used for financing activities was $591.1. The use of cash was driven by cash dividends paid to shareholders of $797.0 and long-term debt repayments of $588.7. Long-term debt repayments included the repayment of $550.0 aggregate principal amount of 1.50% senior notes due October 2025. These uses of cash were partially offset by $439.2 of long-term debt proceeds, primarily from incremental borrowings under the project financing arrangement available to NGHC for the NEOM Green Hydrogen Project. Additionally, we received net proceeds of $269.7 from commercial paper and short-term borrowings, and $120.5 from investments by noncontrolling interests.

For the first six months of fiscal year 2025, cash provided by financing activities was $1.8 billion. The source of cash was driven by long-term debt proceeds of $2.0 billion, which included approximately $1.0 billion from Eurobonds issued in February 2025. We used the proceeds from the offering to repay commercial paper obligations, including those incurred prior to the closing of our 2025 Eurobond offering for repayment of €300 million aggregate principal amount outstanding of our 1.000% Eurobonds at maturity, plus accrued interest. The remaining $1.0 billion was borrowed by the NGHC joint venture as further discussed below. Additionally, we received proceeds of $645.6 from commercial paper and short-term borrowings, and $355.7 from investments by noncontrolling interests. These sources of cash were partially offset by dividend payments to shareholders of $787.4.

Financing and Capital Structure

Debt

Total debt increased to $17.8 billion as of 31 March 2026 from $17.7 billion as of 30 September 2025. The increase in debt was driven by approximately $415 in incremental long-term principal borrowings under the project financing arrangement for the NEOM Green Hydrogen Project, which is non-recourse to Air Products, as further discussed below. Additionally, net issuances of commercial paper and cash received from short-term borrowings totaled $269.7. These borrowings were partially offset by the repayment of $550.0 aggregate principal amount of 1.50% senior notes due October 2025. Total debt included related party debt of $244.3 and $236.5 as of 31 March 2026 and 30 September 2025, respectively.

70

Various debt agreements to which we are a party include financial covenants and other restrictions, including restrictions pertaining to the ability to create property liens and enter into certain sale and leaseback transactions. As of 31 March 2026, we were in compliance with all the financial and other covenants under our debt agreements.

Committed Credit Facilities

On 26 March 2026, we amended our existing 364-day $500 revolving credit agreement to extend its maturity date from 26 March 2026 to 25 March 2027. The amendment also provides that if we elect to convert the facility into a term loan, the maturity date of the term loan would be 25 March 2028. Fees incurred in connection with the amendment were not material.

We also maintain a five-year $3.0 billion revolving credit agreement that matures on 31 March 2029. Both the 364-day agreement and the five-year agreement are syndicated committed facilities that provide a source of liquidity and support our commercial paper program through the availability of senior unsecured debt to us and certain of our subsidiaries. No borrowings were outstanding under either of the agreements as of 31 March 2026 or 30 September 2025.

Separately, certain of our foreign subsidiaries maintain access to committed credit facilities with a combined maximum borrowing capacity of $430.6, of which $337.0 was borrowed and outstanding as of 31 March 2026. The amount available and borrowed as of 30 September 2025 was $394.0.

NEOM Green Hydrogen Project Financing

To support the NEOM Green Hydrogen Project, NGHC has access to project financing of approximately $6.1 billion, which is expected to fund about 73% of the project and is being drawn over the construction period, as well as additional credit facilities totaling approximately $500 primarily for NGHC's working capital needs. Creditors of NGHC do not have recourse to the general credit of Air Products. As of 31 March 2026, the joint venture had borrowed short- and long-term principal amounts totaling $5.4 billion compared to $4.9 billion as of 30 September 2025. Refer to Note 3, Variable Interest Entities, to the consolidated financial statements for additional information.

Dividends

We believe that providing a consistent dividend plays a critical role in creating shareholder value. The Board of Directors determines whether to declare cash dividends on our common stock, and the timing and amount of those dividends, based on our financial condition and other factors it deems relevant. In January 2026, the Board of Directors approved a $0.02 per share increase to our quarterly dividend, raising it to $1.81 per share and marking our 44th consecutive year of dividend increases.

Dividends are paid quarterly, typically during the sixth week following the close of the fiscal quarter. During the first half of fiscal year 2026, we paid $797.0 in dividends to shareholders. Dividends declared but unpaid as of the date of this report were as follows:

Declaration Date	Dividend Per Share	Record Date	Date Payable
27 January 2026	$1.81	1 April 2026	11 May 2026
23 April 2026	$1.81	1 July 2026	10 August 2026

In total, we expect to return approximately $1.6 billion to shareholders in 2026.

71

PENSION BENEFITS

We and certain of our subsidiaries sponsor defined benefit pension plans and defined contribution plans that cover a substantial portion of our worldwide employees. The principal defined benefit pension plans are the U.S. salaried pension plan and the U.K. pension plan. These plans were closed to new participants in 2005, after which defined contribution plans were offered to new employees. The shift to defined contribution plans is expected to continue to reduce volatility of both plan expense and contributions. For additional information, refer to Note 11, Retirement Benefits, to the consolidated financial statements.

Net Periodic Cost

The table below summarizes the components of net periodic cost for our U.S. and international defined benefit pension plans:

	Three Months Ended		Six Months Ended
	31 March		31 March
	2026	2025	2026	2025
Service cost	$4.5	$5.0	$9.4	$10.2
Non-service cost	4.6	10.7	8.0	21.2
Other	0.3	—	0.6	0.1
Net Periodic Cost	$9.4	$15.7	$18.0	$31.5

Net periodic cost was $9.4 and $18.0 for the three and six months ended 31 March 2026, respectively. Net periodic cost was $15.7 and $31.5 for the three and six months ended 31 March 2025, respectively. The lower non-service related costs are the result of higher expected return on plan assets from increases in the return assumption and a decrease in actuarial loss amortization. Non-service related components of net periodic cost are reflected within "Other non-operating income (expense), net" on our consolidated income statements.

Service costs result from benefits earned by active employees and are reflected as operating expenses primarily within "Cost of sales" and "Selling and administrative expense" on our consolidated income statements. The amount of service costs capitalized in the first six months of fiscal years 2026 and 2025 was not material.

Company Contributions

Management considers various factors when making pension funding decisions, including tax, cash flow, and regulatory implications. For the six months ended 31 March 2026 and 2025, our cash contributions to funded pension plans and benefit payments for unfunded pension plans were $13.8 and $14.3, respectively.

Total contributions for fiscal year 2026 are expected to be approximately $25 to $35. During fiscal year 2025, total contributions were $29.9.

72

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

A description of our major accounting policies, including those that we consider to be the most critical to understanding our financial statements, is included in our 2025 Form 10-K. There were no significant changes to our accounting policies during the first six months of fiscal year 2026.

Management’s Discussion and Analysis of our financial condition and results of operations is based on the consolidated financial statements and accompanying notes that have been prepared in accordance with GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates reflect our best judgment about current and/or future economic and market conditions and their effect based on information available as of the date of our consolidated financial statements. If conditions change, actual results may differ materially from these estimates.

Judgments and estimates of uncertainties are required to apply our accounting policies in many areas. However, application of policies that management has identified as critical places significant importance on management’s judgment, often as the result of the need to make estimates about the effects of matters that are inherently uncertain.

During the first six months of fiscal year 2026, we recorded changes to project revenue and cost estimates on certain sale of equipment projects that are accounted for under the cost incurred input method. Accordingly, we recorded cumulative effect adjustments that unfavorably impacted operating income by approximately $25 and $58 for the three and six months ended 31 March 2026, respectively.

Additionally, we recorded a charge of $22.0 within operating income during the first quarter of fiscal year 2026 to update cost estimates related to previously announced project exit decisions as described in Note 4, Business and Asset Actions, to the consolidated financial statements. We estimate the value of certain long-lived assets associated with these decisions using Level 3 inputs under the fair value hierarchy due to the absence of observable market prices and significant reliance on management judgment and estimation techniques. For long-lived assets that met the held-for-sale criteria and are actively being marketed for sale, fair value, including costs to sell, was estimated using an internally developed discounted cash flow analysis as of 30 September 2025. There were no material changes to valuation assumptions related to assets held for sale during the first six months of fiscal year 2026. For plant and equipment that did not meet the held‑for‑sale criteria but are capable of being sold through secondary equipment markets, we estimated the net realizable value of the assets as of 31 March 2025 using an orderly liquidation valuation approach. There were no material changes in the estimated net realizable value for any remaining assets not disposed as of 31 March 2026.

Estimates related to these actions are considered critical because they involve significant assumptions regarding future cash flows, asset disposition strategies, and market conditions, all of which are subject to change and could materially affect the amount and timing of impairment charges. Additionally, because the project review is ongoing, we may make further project-related decisions that could impact the intended use or recoverability of certain assets, potentially resulting in the recognition of additional charges in future periods.

There were no other changes to our estimates during the first six months of fiscal year 2026 that had a significant impact on our financial condition, change in financial condition, liquidity, or results of operations.

73

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Information on our utilization of financial instruments and an analysis of the sensitivity of these instruments to selected changes in market rates and prices is included in our 2025 Form 10-K.

Our net financial instrument position decreased from a liability of $17.2 billion at 30 September 2025 to a liability of $16.8 billion at 31 March 2026. The decrease was primarily due to the repayment of $550.0 principal amount outstanding of our 1.50% U.S. senior note at maturity in October 2025. This decrease was partially offset by approximately $415 of additional long-term principal borrowings under the project financing associated with the NEOM Green Hydrogen Project as discussed in Note 3, Variable Interest Entities, to the consolidated financial statements.

Interest Rate Risk

Our debt portfolio as of 31 March 2026, including the effect of currency and interest rate swap agreements, was composed of 92% fixed-rate debt and 8% variable-rate debt. Our debt portfolio as of 30 September 2025, including the effect of currency and interest rate swap agreements, was composed of 91% fixed-rate debt and 9% variable-rate debt. The decrease in variable-rate debt is primarily due to the maturity of interest rate swaps designated as fair value hedges during October 2025.

The sensitivity analysis related to the interest rate risk on the fixed portion of our debt portfolio assumes an instantaneous 100 bp parallel move in interest rates from the level at 31 March 2026, with all other variables held constant. A 100 bp increase in market interest rates would result in a decrease of $1,044 and $1,128 in the net liability position of financial instruments at 31 March 2026 and 30 September 2025, respectively. A 100 bp decrease in market interest rates would result in an increase of $1,174 and $1,290 in the net liability position of financial instruments at 31 March 2026 and 30 September 2025, respectively.

There were no material changes to the sensitivity analysis related to the variable portion of our debt portfolio since 30 September 2025.

Foreign Currency Exchange Rate Risk

The sensitivity analysis related to foreign currency exchange rates assumes an instantaneous 10% change in the foreign currency exchange rates from their levels at 31 March 2026, with all other variables held constant. A 10% strengthening or weakening of the functional currency of an entity versus all other currencies would result in a decrease or increase, respectively, of $734 and $565 in the net liability position of financial instruments at 31 March 2026 and 30 September 2025, respectively. The increase in sensitivity is primarily due to the origination of cross currency interest rate swaps between the U.S. Dollar and each of the Chinese Renminbi, South Korean Won, and New Taiwan Dollar.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We maintain a comprehensive set of disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Under the supervision of the Chief Executive Officer and Chief Financial Officer, our management conducted an evaluation of the effectiveness of our disclosure controls and procedures as of 31 March 2026. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of 31 March 2026, our disclosure controls and procedures were effective.

Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended 31 March 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

74

PART II—OTHER INFORMATION

Section 5Governing Law.

Section 6Counterparts. This Amendment may be executed in any number of counterparts and by the different parties hereto on separate counterparts each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute but one and the same instrument. Delivery by fax or other electronic transmission of an executed counterpart of a signature page to this Amendment shall be effective as delivery of an original executed counterpart of this Amendment and the words “execution,” “execute”, “signed,” “signature,” and words of like import in or related to any document to be signed in connection with this Amendment shall be deemed to include electronic signatures, the electronic matching of assignment terms and contract formations on electronic platforms approved by the Administrative Agent, or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. The Administrative Agent may, in its discretion, require that any such documents and signatures executed electronically or delivered by fax or other electronic transmission be confirmed by a manually-signed original thereof; provided that the failure to request or deliver the same shall not limit the effectiveness of any document or signature executed electronically or delivered by fax or other electronic transmission.

Section 7Waiver of Jury Trial. Each party hereto waives the right to trial by jury in any action, suit or proceeding (whether in contract, tort or otherwise and whether at law or in equity) by any person arising from or relating to this Amendment or any other Loan Document or any statement, course of conduct, act, omission or event occurring in connection herewith or therewith (collectively, “Related Litigation”). In addition, each Borrower hereby irrevocably and unconditionally:

(a)Agrees that any Related Litigation by any Lender or Administrative Agent may be brought in any state or federal court of competent jurisdiction sitting in New York county, New York, and submits to the jurisdiction of such courts (but nothing herein shall affect the right of the Parent or any Administrative Agent or any Lender or Borrower to bring any action, suit or proceeding in any other forum);

(b)Waives any objection which it may have at any time to the laying of venue of any related litigation brought in any such court, waives any claim that any such related litigation has been brought in an inconvenient forum, and waives any right to object, with respect to any related litigation brought in any such court, that such court does not have jurisdiction over such Borrower; and

(c)Consents and agrees to service of any summons, complaint or other legal process in any related litigation by registered or certified U.S. mail, postage prepaid, to such Borrower at the address for notices pursuant to Section 12.05 of the Credit Agreement, and consents and agrees that such service shall constitute in every respect valid and effective service (but nothing herein shall affect the validity or effectiveness of process served in any other manner permitted by law).

Section 8Miscellaneous. On and after the Amendment No. 2 Effective Date, each reference in the Existing Credit Agreement to the Existing Credit Agreement, “hereunder”, “herein” or words of like import referring thereto, and each reference in the other Loan Documents to the Existing Credit Agreement, “thereunder”, “thereof” or words of like import referring thereto, shall mean and be a reference to the Credit Agreement. Except as specifically amended by this Amendment, the Existing

3

Credit Agreement and the other Loan Documents shall remain in full force and effect and are hereby ratified and confirmed (including all Obligations and Guarantee Obligations thereunder), and this Amendment shall not be considered a novation. The execution, delivery and performance of this Amendment shall not constitute a waiver of any provision of, or operate as a waiver of any right, power or remedy of the Administrative Agent or any Lender under, the Credit Agreement or any of the other Loan Documents. This Amendment shall constitute a “Loan Document” for all purposes of the Credit Agreement and the other Loan Documents.

New Accounting Guidance to be Implemented

Climate-Related Disclosures

In March 2024, the SEC issued Release No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors", which includes final rules for providing annual qualitative and quantitative disclosures regarding certain climate-related topics. As a result of legal challenges, the SEC issued an order in April 2024 to stay the effectiveness of the rules pending the completion of judicial review of the consolidated challenges before the United States Court of Appeals for the Eighth Circuit.

The SEC subsequently announced its withdrawal of its legal defense to such challenges in March 2025; however, the rules have not been formally rescinded by the SEC. In April 2025, the appellate court suspended its proceedings indefinitely and directed the SEC to file a status report outlining its next steps. In response, the SEC stated in July 2025 that it does not intend to revisit the rules and requested the court to rule on the pending petitions.

In September 2025, the appellate court declined the SEC's request and placed the litigation in abeyance, which will remain in effect until the SEC reconsiders the rules by notice-and-comment rulemaking or renews its defense. We continue to monitor these developments.

Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740)—Improvements to Income Tax Disclosures”, to expand income tax disclosures, primarily through disaggregation requirements for the rate reconciliation and income taxes paid. The update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2026, although early adoption is permitted. The amendments should be applied on a prospective basis with a retrospective option. We are evaluating the impact this update will have on our disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires additional disclosures of certain costs and expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization, as well as selling expenses in the notes to the financial statements. In January 2025, the FASB clarified that the update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2028 as well as interim periods thereafter, although early adoption is permitted. The amendments should be applied either prospectively after the effective date or retrospectively to any or all periods presented. We are evaluating the impact this update will have on our disclosures.

Measurement of Credit Losses for Accounts Receivable and Contract Assets

In July 2025, the FASB issued ASU 2025-09, “Measurement of Credit Losses for Accounts Receivable and Contract Assets”, which allows an entity to elect a practical expedient to assume that current conditions as of the balance sheet date do not change when estimating expected credit losses. This update will be effective at the beginning of fiscal year 2027, although early adoption is permitted. The amendments should be applied on a prospective basis. We are evaluating the implications of this update. At this time, we do not expect it will have a material impact on our financial statements.

Accounting for Internal-Use Software

In September 2025, the FASB issued ASU 2025-06, “Targeted Improvements to the Accounting for Internal-Use Software”, which establishes criteria for commencing cost capitalization for software projects. This update will be effective at the beginning of fiscal year 2029, although early adoption is permitted. The amendments can be applied prospectively, retrospectively, or via a modified prospective transition method. We are evaluating the impact this update will have on our financial statements.

Government Grants

In December 2025, the FASB issued ASU 2025-10, “Accounting for Government Grants Received by Business Entities”, which provides guidance on the recognition, measurement, and presentation of government grants. This update will be effective at the beginning of fiscal year 2030, although early adoption is permitted. The amendments can be applied on a modified prospective approach, modified retrospective approach, or a full retrospective approach. We are evaluating the impact this update will have on our financial statements.

Interim Reporting

In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements”. This guidance addresses the form and content of interim financial statements, lists interim disclosures required by other codification topics, and establishes a principle for disclosing events since the end of the last annual reporting period that have a material impact. This update will be effective for interim periods beginning in fiscal year 2029, although early adoption is permitted. The ASU can be applied prospectively or retrospectively. We are evaluating the impact this update will have on our disclosures.

Variable Interest Entities

6 Months Ended

Consolidated Variable Interest Entities Disclosure [Abstract]

Variable Interest Entities

VARIABLE INTEREST ENTITIES

We are the primary beneficiary of the NEOM Green Hydrogen Company joint venture ("NGHC"), a variable interest entity ("VIE") that is consolidated in our Middle East and India segment. We are not the primary beneficiary of any other material VIEs.

Our other material VIEs are those in which we hold variable interests but are not the primary beneficiary. We have an equity interest and exercise significant influence in the Jazan Integrated Gasification and Power Company joint venture ("JIGPC"), which we account for as an equity method investment in our Middle East and India segment. We have no equity interest in World Energy, LLC ("World Energy"), but hold a variable interest through a financing receivable that was fully reserved in connection with our exit from the sustainable aviation fuel ("SAF") expansion project during the second quarter of fiscal year 2025.

NGHC Joint Venture

The NEOM Green Hydrogen Project is a multi-billion dollar green hydrogen-based ammonia production facility that is being constructed in NEOM City, Saudi Arabia. Owned and operated by NGHC, the facility will be powered by renewable energy to produce green ammonia for Air Products as the exclusive offtaker under a long-term take-if-tendered agreement.

Air Products is an equal owner in NGHC with our joint venture partners, ACWA Power and NEOM Company. While we only hold one-third of the voting interests in the joint venture, substantially all the activities of the joint venture involve or are conducted on behalf of Air Products. Since we have disproportionately few voting rights relative to our economic interests in the joint venture, we determined that NGHC is a VIE. In addition, we determined that we are the primary beneficiary of NGHC since we have the power to unilaterally direct certain significant activities, including key design and construction decisions, and we share power with our joint venture partners related to other activities that are significant to the economic performance of NGHC. Therefore, we consolidate NGHC within the Middle East and India segment.

Under the project financing discussed below, the assets of NGHC can only be used to settle obligations of the joint venture, and creditors of NGHC do not have recourse to the general credit of Air Products. A table summarizing balances associated with NGHC as reflected on our consolidated balance sheets is provided on page 15.

Project Financing

In May 2023, NGHC finalized the $6.7 billion engineering, procurement, and construction agreement, naming Air Products as the main contractor and system integrator for the facility. To support the project, NGHC secured project financing that is non-recourse to Air Products of approximately $6.1 billion, which is expected to fund about 73% of the project and is being drawn over the construction period. At the same time, NGHC secured additional credit facilities totaling approximately $500, primarily for NGHC's working capital needs. These facilities are also non-recourse to Air Products. Total principal borrowings were $5.4 billion and $4.9 billion as of 31 March 2026 and 30 September 2025, respectively. Long-term principal borrowings of approximately $415 during the first six months of fiscal year 2026 were primarily drawn under a 2.00% stated-rate Saudi Riyal facility.

The borrowings discussed above are primarily from long-term facilities that are presented net of unamortized discounts and debt issuance costs within "Long-term debt" on our consolidated balance sheets. Short-term borrowings were $46.5 and $24.0 as of 31 March 2026 and 30 September 2025, respectively, under a variable-rate Saudi Riyal facility that carried an interest rate of 5.02% as of 31 March 2026.

Interest Rate Swaps

In May 2023, NGHC entered into floating-to-fixed interest rate swaps designed to hedge long-term variable-rate debt facilities available under the project financing during the construction period. In fiscal year 2024, we discontinued cash flow hedge accounting for certain swaps due to changes in the anticipated drawdown timeline for the hedged borrowings. As a result of the de-designation, unrealized gains and losses related to the affected swaps were recorded in "Other non-operating income (expense), net" on our consolidated income statements.

During the three months ended 31 March 2025, we recorded an unrealized loss of $11.5 ($7.5 attributable to our noncontrolling partners, or $3.0 attributable to Air Products after tax). For the six months ended 31 March 2025, the total amount recorded was a net unrealized gain of $27.3 ($17.7 attributable to our noncontrolling partners, or $7.3 attributable to Air Products after tax).

We re-designated the affected swaps as cash flow hedges when the outstanding borrowings under the available project financing became commensurate with the swaps’ notional values. As of 1 January 2026, all swaps were re-designated as cash flow hedges. The unrealized gain on swaps that remained de-designated during the first quarter of fiscal year 2026 was not material.

JIGPC Joint Venture

JIGPC is a joint venture with Saudi Aramco Power Company (a subsidiary of Aramco), ACWA Power, and Air Products Qudra (“APQ”). JIGPC entered into project financing to purchase power blocks, gasifiers, air separation units, syngas cleanup assets, and utilities to supply electricity, steam, hydrogen, and utilities to Aramco’s refinery and terminal complex under a 25-year agreement, which commenced in the first quarter of fiscal year 2022. JIGPC recorded financing receivables upon acquisition of the assets and recognizes financing income over the supply term.

We determined JIGPC is a VIE for which we exercise significant influence but are not the primary beneficiary as we do not have the power to direct the activities that are most significant to its economic performance. Instead, these activities, including plant dispatch, operating and maintenance decisions, budgeting, capital expenditures, and financing, require unanimous approval of the owners or are controlled by the customer. Accordingly, we account for our 55% investment, which includes 4% that is attributable to the noncontrolling partner of APQ, under the equity method within the Middle East and India segment.

Our loss exposure is limited to the carrying value of our investment in the joint venture which, including amounts attributable to noncontrolling interests, totaled approximately $3.0 billion and $3.1 billion as of 31 March 2026 and 30 September 2025, respectively.

Our total investment in JIGPC primarily consists of shareholder loans that qualify as in-substance common stock in the joint venture. Certain shareholders receive a preferred cash distribution pursuant to the joint venture agreement, which specifies each shareholder’s share of income after considering the amount of cash available for distribution. As such, the earnings attributable to Air Products may not be proportionate to our ownership interest in the venture.

World Energy

In November 2023, we purchased an SAF facility in Paramount, California, from World Energy and accounted for the transaction as a financing arrangement because the agreement contained an embedded sales-type lease. Additionally, we entered into a Master Project Agreement ("MPA") that included terms for operation of the acquired facility as well as amended terms for the construction and operation of an SAF expansion project subject to construction at the same location. We determined that World Energy is a VIE, and our financing receivable represented a variable interest in World Energy. We are not the primary beneficiary as we did not control key operating decisions.

In February 2025, we terminated the MPA and announced our decision to exit the project. Cumulative project exit charges recorded in connection with this decision total approximately $1.9 billion, the majority of which were recognized in the second quarter of fiscal year 2025 and primarily related to the write-down of plant and equipment. We have no further loss exposure related to our variable interest in World Energy because these charges also included the establishment of an allowance for credit loss equal to the value of the financing receivable. However, future impacts to earnings may occur as we finalize our exit from the project.

Project exit charges related to World Energy were recorded with other business and asset actions discussed in Note 4, Business and Asset Actions.

Business and Asset Actions

BUSINESS AND ASSET ACTIONS

Our consolidated income statement for the six months ended 31 March 2026 includes charges for business and asset actions of $28.3 ($24.6 after tax) related to project exit decisions reached in fiscal year 2025. Of these charges, $22.0 were recorded to operating income to update cost estimates as we settle project‑related commitments and dispose of associated assets, and $6.3 were recorded in "Other non‑operating income (expense), net" for losses on cross‑currency interest rate swaps terminated in connection with the early repayment of related intercompany loans for one of the affected gasification projects in China. No additional charges were recorded during the second quarter of fiscal year 2026.

Our consolidated prior-year income statements for the three and six months ended 31 March 2025 included charges of approximately $2.9 billion, reflecting initial project exit charges as well as costs incurred in connection with our global cost reduction plan. Of these charges, $2.3 billion was attributable to Air Products after tax ($3.5 attributable to noncontrolling partners), including $6.8 recorded in equity affiliates’ income related to an other‑than‑temporary impairment of a joint venture in China formed to develop clean hydrogen infrastructure in the region.

Project Exit Costs

Project exit decisions reached in fiscal year 2025 were part of a review initiated by our Board of Directors and Chief Executive Officer to focus resources on projects we believe will deliver the greatest value to our shareholders. These actions primarily affected clean‑energy generation and distribution projects, including three U.S.-based projects within the Americas segment, as well as several smaller-scale projects across our global portfolio. The exit decisions were driven by several factors, including challenging commercial conditions and unfavorable regulatory actions, as well as customer‑related challenges for two coal gasification plants in China that resulted in assets and liabilities being classified as held for sale. Assets held for sale as of 31 March 2026 and 30 September 2025 primarily included plant and equipment. We continue to pursue the sale of these assets and remain engaged in marketing and negotiation efforts.

Cumulative charges incurred in connection with these decisions total approximately $3.6 billion, the majority of which were recognized in the second quarter of fiscal year 2025. Noncash expenses of approximately $3.3 billion included $2.5 billion to write down plant and equipment, with the remainder primarily related to other assets associated with our exit from the SAF expansion project with World Energy as discussed in Note 3, Variable Interest Entities.

Cash obligations primarily relate to costs to terminate contractual commitments and settle asset retirement obligations. Total cash outflows are expected to be approximately $360 once the actions are fully implemented. Approximately $240 has been paid through 31 March 2026.

The table below provides a reconciliation of the beginning and ending liability balances associated with project exit activities, which are reflected within “Payables and Accrued Liabilities” on our consolidated balance sheets:

Amount accrued as of 30 September 2025	$178.3
Changes in estimates	9.3
Cash payments	(67.0)
Amount accrued as of 31 March 2026	$120.6

Both the held-for-sale assets and other marketable plant and equipment were subject to Level 3 fair value measurements due to the use of significant unobservable inputs. There were no material changes to the valuation assumptions during the first six months of fiscal year 2026. Refer to Note 9, Fair Value Measurements, for additional information.

Estimates related to the actions described above reflect our best judgment based on information available at the time the charges were recorded. Final settlement of these items may differ materially from current estimates, which could impact our consolidated financial statements in future periods. While we expect the related exit activities to be substantially completed in fiscal year 2026, we cannot predict the occurrence of future events and circumstances that could extend the timing of certain actions beyond this period. In addition, the related project review remains ongoing and may result in additional costs in future periods.

Global Cost Reduction Plan

In June 2023, we initiated a global cost reduction plan that provides severance and other postemployment benefits to employees designated for involuntary separation. In accordance with our accounting policy, we recognize related costs in the period management formally commits to a defined set of actions under the plan. Benefits are determined based on the terms of our established ongoing benefit arrangements. Since the plan was initiated, we have incurred cumulative costs totaling $207.7 for approximately 3,600 employees globally. No costs were recorded for the plan during the first half of fiscal year 2026. Our consolidated prior-year income statement reflects costs of $66.1 for actions identified during the second quarter of fiscal year 2025.

The table below provides a reconciliation of the beginning and ending liability balances associated with our global cost reduction plan, which are reflected within “Payables and Accrued Liabilities” on our consolidated balance sheets:

Amount accrued as of 30 September 2025	$101.6
Cash payments	(29.8)
Currency translation adjustment	(0.5)
Amount accrued as of 31 March 2026	$71.3

The remaining liability as of 31 March 2026 relates to employees identified during fiscal year 2025. We expect implementation of these actions to be substantially complete by the end of fiscal year 2026. However, position eliminations are subject to legal requirements that vary by jurisdiction, which may extend this process beyond this period in certain cases.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

REVENUE RECOGNITION

The majority of our revenue is generated from our sale of gas customers within the regional industrial gases segments. We distribute product to our industrial gas customers through either our on-site or merchant supply mode depending on various factors, including the customer's volume requirements and location. We also design and manufacture equipment for air separation, hydrocarbon recovery and purification, and liquid helium and liquid hydrogen transport and storage. The Corporate and other segment serves our sale of equipment customers.

Disaggregation of Revenue

The tables provided below present our consolidated sales disaggregated by supply mode for each of our reportable segments. We believe this presentation best depicts the nature, timing, type of customer, and contract terms for our sales.

Interest income associated with financing and lease arrangements accounted for approximately 1% of our total consolidated sales for the periods presented.

Remaining Performance Obligations

As of 31 March 2026, the transaction price allocated to remaining performance obligations is estimated to be approximately $28 billion. This amount includes fixed-charge contract provisions associated with our on-site and sale of equipment supply modes. We estimate that approximately half of this revenue will be recognized over the next five years and the balance thereafter.

Our remaining performance obligations do not include (1) expected revenue associated with new on-site plants that are not yet on-stream; (2) consideration associated with contracts that have an expected duration of less than one year; and (3) variable consideration for which we recognize revenue at the amount to which we have the right to invoice, including energy cost pass-through to customers.

In the future, actual amounts will differ due to events outside of our control, including, but not limited to, inflationary price escalations; currency exchange rates; and amended, terminated, or renewed contracts.

FINANCIAL INSTRUMENTS

Currency Price Risk Management

Our earnings, cash flows, and financial position are exposed to foreign currency risk from foreign currency-denominated transactions and net investments in foreign operations. It is our policy to seek to minimize our cash flow volatility from changes in currency exchange rates. This is accomplished by identifying and evaluating the risk that our cash flows will change in value due to changes in exchange rates and by executing strategies necessary to manage such exposures. Our objective is to maintain economically balanced currency risk management strategies that provide adequate downside protection.

Forward Exchange Contracts

We enter into forward exchange contracts to reduce the cash flow exposure to foreign currency fluctuations associated with highly anticipated cash flows and certain firm commitments, such as the purchase of plant and equipment. We also enter into forward exchange contracts to hedge the cash flow exposure on intercompany loans and third-party debt. This portfolio of forward exchange contracts consists primarily of the U.S. Dollar and each of the Chinese Renminbi, Canadian Dollar, and South Korean Won. The maximum remaining term of any forward exchange contract currently outstanding and designated as a cash flow hedge at 31 March 2026 is 2.3 years.

Forward exchange contracts are also used to hedge the value of investments in certain foreign subsidiaries and affiliates by creating a liability in a currency in which we have a net equity position. The primary currency pair in this portfolio of forward exchange contracts is the U.S. Dollar and Chilean Peso.

We also utilize forward exchange contracts that are not designated as hedges. These contracts are used to economically hedge foreign currency-denominated monetary assets and liabilities, primarily working capital. The primary objective of these forward exchange contracts is to protect the value of foreign currency-denominated monetary assets and liabilities from the effects of volatility in foreign exchange rates that might occur prior to their receipt or settlement. This portfolio of forward exchange contracts consists of multiple foreign currency pairs, with a profile that changes from time to time depending on our business activity and sourcing decisions.

The table below summarizes our outstanding currency price risk management instruments:

	31 March 2026		30 September 2025
	US$ Notional	Years Average Maturity	US$ Notional	Years Average Maturity
Forward Exchange Contracts:
Cash flow hedges	$4,250.1	0.5	$3,625.5	0.6
Net investment hedges	76.8	0.3	73.9	0.8
Not designated	2,105.2	1.2	2,968.6	1.2
Total Forward Exchange Contracts	$6,432.1	0.7	$6,668.0	0.9

We also use foreign currency-denominated debt to hedge the foreign currency exposures of our net investment in certain foreign subsidiaries. The designated foreign currency-denominated debt and related accrued interest was €3,142.0 million ($3,631.9 million) at 31 March 2026 and €3,188.1 million ($3,741.5 million) at 30 September 2025. The designated foreign currency-denominated debt is presented within "Long-term debt" on our consolidated balance sheets.

Debt Portfolio Management

It is our policy to identify, on a continuing basis, the need for debt capital and to evaluate the financial risks inherent in funding the Company with debt capital. Reflecting the result of this ongoing review, we manage our debt portfolio and hedging program with the intent to (1) reduce funding risk with respect to borrowings made by us to preserve our access to debt capital and provide debt capital as required for funding and liquidity purposes, and (2) manage the aggregate interest rate risk and the debt portfolio in accordance with certain debt management parameters.

Interest Rate Management Contracts

We enter into interest rate swaps to change the fixed/variable interest rate mix of our debt portfolio in order to maintain the percentage of fixed- and variable-rate debt within the parameters set by management. In accordance with these parameters, the agreements are used to manage interest rate risks and costs inherent in our debt portfolio. Our interest rate management portfolio generally consists of fixed-to-floating interest rate swaps (which are designated as fair value hedges), pre-issuance interest rate swaps and treasury locks (which hedge the interest rate risk associated with anticipated fixed-rate debt issuances and are designated as cash flow hedges), and floating-to-fixed interest rate swaps (which are designated as cash flow hedges). As of 31 March 2026, the outstanding interest rate swaps were denominated in U.S. Dollars. The notional amount of the interest rate swap agreements is equal to or less than the designated debt being hedged. When interest rate swaps are used to hedge variable-rate debt, the indices of the swaps and the debt to which they are designated are the same. It is our policy not to enter into any interest rate management contracts which lever a move in interest rates on a greater than one-to-one basis.

Cross Currency Interest Rate Swap Contracts

We enter into cross currency interest rate swap contracts when our risk management function deems necessary. These contracts may entail both the exchange of fixed- and floating-rate interest payments periodically over the life of the agreement and the exchange of one currency for another currency at inception and at a specified future date. The contracts are used to hedge either certain net investments in foreign operations or non-functional currency cash flows related to intercompany loans. The current cross currency interest rate swap portfolio consists of fixed-to-fixed swaps primarily between the U.S. Dollar and each of the Chinese Renminbi, South Korean Won, and New Taiwan Dollar.

The table below summarizes our outstanding interest rate management contracts and cross currency interest rate swaps:

	31 March 2026						30 September 2025

(A)We temporarily discontinued cash flow hedge accounting for certain floating-to-fixed interest rate swaps related to project financing for the NEOM Green Hydrogen Project beginning in the third quarter of fiscal year 2024 due to changes in the anticipated drawdown timeline for the hedged borrowings. As of 1 January 2026, all swaps were re-designated as cash flow hedges. Refer to Note 3, Variable Interest Entities, for additional information.

Credit Risk-Related Contingent Features

Certain derivative instruments are executed under agreements that require us to maintain a minimum credit rating with both Standard & Poor’s and Moody’s. If our credit rating falls below this threshold, the counterparty to the derivative instruments has the right to request full collateralization on the derivatives’ net liability position. The net liability position of derivatives with credit risk-related contingent features was $91.3 and $43.3 as of 31 March 2026 and 30 September 2025, respectively. Because our current credit rating is above the various pre-established thresholds, no collateral has been posted on these liability positions.

Counterparty Credit Risk Management

We execute financial derivative transactions with counterparties that are highly rated financial institutions, all of which are investment grade at this time. Some of our underlying derivative agreements give us the right to require the institution to post collateral if its credit rating falls below the pre-established thresholds with Standard & Poor’s, Moody’s, or Fitch. The collateral that the counterparties would be required to post was $259.6 and $174.0 as of 31 March 2026 and 30 September 2025, respectively. No financial institution is required to post collateral at this time, as all have credit ratings at or above threshold.

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

Fair value is defined as an exit price, or the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows:

Level 1    — Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2    — Inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability.

Level 3    — Inputs that are unobservable for the asset or liability based on our own assumptions about the assumptions market participants would use in pricing the asset or liability.

The methods and assumptions used to measure the fair value of financial instruments are as follows:

Derivatives

The fair value of our interest rate management contracts and forward exchange contracts are quantified using the income approach and are based on estimates using standard pricing models. These models consider the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. These standard pricing models utilize inputs that are derived from or corroborated by observable market data such as interest rate yield curves as well as currency spot and forward rates; therefore, the fair value of our derivatives is classified as a Level 2 measurement. On an ongoing basis, we randomly test a subset of our valuations against valuations received from the transaction’s counterparty to validate the accuracy of our standard pricing models. Counterparties to these derivative contracts are highly rated financial institutions.

Refer to Note 8, Financial Instruments, for a description of derivative instruments, including details related to the balance sheet line classifications.

Long-term Debt, Including Related Party

The fair value of our debt is based on estimates using standard pricing models that consider the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. These standard valuation models utilize observable market data such as interest rate yield curves and currency spot rates; therefore, the fair value of our debt is classified as a Level 2 measurement.

The carrying values and fair values of financial instruments were as follows:

	31 March 2026		30 September 2025
	Carrying Value	Fair Value	Carrying Value	Fair Value
Assets

Long-term debt, including current portion and related party	17,443.4	16,975.9	17,663.7	17,348.7

The carrying amounts reported on the consolidated balance sheets for cash and cash items, trade receivables, payables and accrued liabilities, accrued income taxes, and short-term borrowings approximate fair value due to the short-term nature of these instruments. Accordingly, these items have been excluded from the above table.

Nonrecurring Fair Value Measurements – Project Exit Activities

We estimate the value of certain long-lived assets associated with exited projects using Level 3 inputs under the fair value hierarchy due to the absence of observable market prices and significant reliance on management judgment and estimation techniques. These assets are described below. For additional information regarding project exit activities, refer to Note 4, Business and Asset Actions.

Long-lived assets that met the held-for-sale criteria and are actively being marketed for sale.

Because there were no observable market prices available, fair value, including costs to sell, for long-lived assets that met the held-for-sale criteria was estimated using an internally developed discounted cash flow analysis, which resulted in an impairment charge of $350.6 in the fourth quarter of fiscal year 2025. There were no material changes to valuation assumptions during the first six months of fiscal year 2026. Any gain or loss from the sales will be recognized upon closing of any such transaction based on the carrying amounts classified as held for sale. Interim adjustments may be recorded prior to closing if market participant assumptions or other valuation inputs change, including updates to expected selling price or transaction timing.

Plant and equipment that did not meet the held‑for‑sale criteria but are capable of being sold through secondary equipment markets.

These assets were evaluated for recoverability in fiscal year 2025, and the resulting impairment loss of approximately $2.1 billion was recorded primarily during the second quarter using an orderly liquidation valuation approach. The impairment charge reflects the difference between the estimated liquidation value and the net book value of the assets as of 31 March 2025. There were no material changes in the estimated net realizable value for any remaining assets not disposed as of 31 March 2026.

The table below presents the nonrecurring fair value measurements of these long-lived assets, categorized within the fair value hierarchy:

Balance Sheet Location	Total Estimated Value	Level 1	Level 2	Level 3
Assets held for sale	$454.7	$—	$—	$454.7

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Litigation

We are involved in various legal proceedings, including commercial, competition, environmental, intellectual property, regulatory, product liability, and insurance matters. We do not currently believe there are any legal proceedings for which it is reasonably possible, individually or in the aggregate, to have a material impact on our financial condition, results of operations, or cash flows.

Environmental

In the normal course of business, we are involved in legal proceedings under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA," the federal Superfund law), the Resource Conservation and Recovery Act ("RCRA"), and similar state and foreign environmental laws relating to the designation of certain sites for investigation or remediation. Presently, there are 26 sites on which a final settlement or remediation has not been achieved where we, usually along with others, have been designated as a potentially responsible party by environmental authorities or are otherwise engaged in investigation or remediation, including cleanup activity at certain of our former and current manufacturing sites. We continually monitor these sites for which we have environmental exposure.

Accruals for environmental loss contingencies are recorded when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. As of 31 March 2026 and 30 September 2025, the consolidated balance sheets included accruals of $83.9 and $85.6, respectively, primarily as part of other noncurrent liabilities. These environmental liabilities will be paid over a period of up to 30 years. We estimate the exposure for environmental loss contingencies to range from $83 to a reasonably possible upper exposure of $97 as of 31 March 2026.

Actual costs to be incurred at identified sites in future periods may vary from the estimates, given inherent uncertainties in evaluating environmental exposures. Using reasonably possible alternative assumptions of the exposure level could result in an increase to the environmental accrual. Due to these inherent uncertainties, a significant increase to the reasonably possible upper exposure level could occur if a new site is designated, the scope of remediation is increased, a different remediation alternative is identified, or a significant increase in our proportionate share occurs. We do not expect that any sum we may have to pay in connection with environmental matters in excess of the amounts recorded or disclosed above would have a material adverse impact on our financial position or results of operations in any one year.

Pace

As of 31 March 2026, $53.1 of the environmental accrual was related to our facility in Pace, Florida.

In 2006, we sold our Amines business, which included operations at the Pace facility and recognized a liability for retained environmental obligations associated with remediation activities at the facility. We are required by the Florida Department of Environmental Protection ("FDEP") and the United States Environmental Protection Agency ("USEPA") to continue our remediation efforts. We recognized a before-tax expense of $42 in fiscal year 2006 in results from discontinued operations and recorded an environmental accrual of $42 in continuing operations on the consolidated balance sheets.

In the first quarter of 2015, we entered into a consent order with the FDEP requiring us to continue our remediation efforts at the Pace facility and complete a cost review every five years. In fiscal year 2020, we completed an updated cost review of the environmental remediation status at the Pace facility and increased our environmental accrual for this site by $19 in continuing operations on the consolidated balance sheet and recognized a before-tax expense of $19 in results from discontinued operations. In fiscal year 2024, we completed our most recent cost review of the environmental remediation status at the Pace facility. Based on our review, we expect ongoing activities to continue for 30 years. Additionally, we increased our estimate of near-term spending for an optimized groundwater recovery system and future annual costs due to higher inflation. As a result of these changes, we increased our environmental accrual for this site by $19 in continuing operations on the consolidated balance sheets and recognized a before-tax expense of $19 in results from discontinued operations in fiscal year 2024. There have been no significant changes to the estimated exposure.

We have implemented many of the remedial corrective measures at the Pace facility required under the 1995 consent orders issued by the FDEP and the USEPA. Contaminated soils have been bioremediated, and the treated soils have been secured in a lined on-site corrective action management unit. Several groundwater recovery systems have been installed to contain and remove contamination from groundwater. We completed an extensive assessment of the site to determine the efficacy of existing measures, what additional corrective measures may be needed, and whether newer remediation technologies that were not available in the 1990s might be better suited for groundwater remediation. Based on assessment results, we completed a focused feasibility study that identified alternative approaches that may more effectively remove contaminants. We continue to review alternative remedial approaches with the FDEP, and we completed additional field work during 2021 to support the design of an improved groundwater recovery network. This network targets areas of higher contaminant concentration and avoids areas of high groundwater iron which has proven to be a significant operability issue for the project. The design of the optimized recovery system was completed in fiscal year 2024, with construction expected to begin in fiscal year 2026. In the fourth quarter of fiscal year 2024, we completed an updated cost review which resulted in a change in assumptions regarding future operating costs as discussed above.

Piedmont

As of 31 March 2026, $9.8 of the environmental accrual was related to a production facility site in Piedmont, South Carolina.

On 30 June 2008, we sold our Elkton, Maryland, and Piedmont, South Carolina, production facilities and the related North American atmospheric emulsions and global pressure sensitive adhesives businesses. In connection with the sale, we recognized a liability for retained environmental obligations associated with remediation activities at the Piedmont site. This site is under active remediation for contamination caused by an insolvent prior owner.

We are required by the South Carolina Department of Environmental Services ("SCDES") to address both contaminated soil and groundwater. Numerous areas of soil contamination have been addressed, and contaminated groundwater is being recovered and treated. The SCDES issued its final approval to the site-wide feasibility study on 13 June 2017 and the Record of Decision for the site on 27 June 2018, after which we signed a Consent Agreement Amendment memorializing our obligations to complete the cleanup of the site.

Remediation has started in accordance with the design, which includes in-situ chemical oxidation treatment, as well as soil vapor extraction to remove volatile organic compounds from the unsaturated soils beneath the impacted areas of the plant. We estimate that source area remediation and groundwater recovery and treatment will continue through 2033. Thereafter, we currently expect this site to go into a state of monitored natural attenuation through 2038. We recognized a before-tax expense of $24 in 2008 as a component of income from discontinued operations and recorded an environmental liability of $24 in continuing operations on the consolidated balance sheets.

In the third quarter of fiscal year 2025, we completed an updated cost review of the environmental remediation status at Piedmont. Based on our review, we increased our estimate of remaining costs due to the extended period of time that will be required to complete the remediation along with higher annual costs due to inflation. As a result of these changes, we increased the environmental accrual for this site by $9 in continuing operations on the consolidated balance sheets and recognized a before-tax expense of $9 in results from discontinued operations.

Pasadena

As of 31 March 2026, $9.7 of the environmental accrual was related to a production facility site in Pasadena, Texas.

During fiscal year 2012, management committed to permanently shutting down our polyurethane intermediates production facility in Pasadena, Texas. In shutting down and dismantling the facility, we have undertaken certain obligations related to soil and groundwater contaminants. We have been pumping and treating groundwater to control off-site contaminant migration in compliance with regulatory requirements and under the approval of the Texas Commission on Environmental Quality ("TCEQ"). We estimate that the pump and treat system will continue to operate until 2042.

We continue to perform additional work to address other environmental obligations at the site. This additional work includes remediating impacted soils as required, maintaining recovery wells, continuing post closure care for two closed RCRA surface impoundment units, and maintaining engineering controls. Additionally, we have conducted an interim corrective action to treat impacted soils as recommended in the TCEQ 2019 Annual Report. We are currently in the process of renewing the site's RCRA permit. In 2012, we estimated the total exposure at this site to be $13. There have been no significant changes to the estimated exposure.

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

SHARE-BASED COMPENSATION

Our share-based compensation program includes performance and time-based deferred stock units. We issue shares from treasury stock upon the payout of deferred stock units. As of 31 March 2026, there were 0.6 million shares available for future grant under our Long-Term Incentive Plan ("LTIP"), which is shareholder approved.

Share-based compensation cost recognized on the consolidated income statements is summarized below:

	Three Months Ended		Six Months Ended
	31 March		31 March
	2026	2025	2026	2025
Before-tax share-based compensation cost(A)	$16.0	$38.3	$26.3	$54.8
Income tax benefit	(3.8)	(9.0)	(6.2)	(13.0)
After-tax share-based compensation cost	$12.2	$29.3	$20.1	$41.8

(A)Fiscal year 2025 includes noncash executive separation costs of $22.4 to accelerate vesting of share-based awards. Refer to the "Shareholder Activism-Related Costs" disclosure in Note 17, Supplemental Information, for additional information.

Before-tax share-based compensation cost is primarily included in "Selling and administrative expense" on our consolidated income statements. The amount of share-based compensation cost capitalized in the first six months of fiscal years 2026 and 2025 was not material.

Deferred Stock Units

During the six months ended 31 March 2026, we granted 100,048 performance shares to be earned over the performance period beginning 1 October 2025 and ending 30 September 2028.

The award conditions are equally weighted between market-based awards, which consider total shareholder return ("TSR") measured against a fixed group of companies that comprise the S&P 500 Industrials Index and the S&P Materials Index and awards that consider an internal performance measure for return on capital.

The fair value of the portion of the awards subject to the achievement of return on capital targets were valued based on the closing stock price of $260.86 on the grant date. The portion of the awards subject to market conditions were valued using a Monte Carlo simulation on the date of grant with an estimated grant-date fair value of $275.21 per unit. The model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the grant and calculates the fair value of the awards.

The calculation of the fair value of market-based deferred stock units used the following assumptions:

Expected volatility	34.5	%
Risk-free interest rate	3.6	%
Expected dividend yield	2.7	%

In addition, during the six months ended 31 March 2026, we granted 130,557 time-based deferred stock units at a weighted average grant-date fair value of $260.73.

We generally expense the grant-date fair value of these awards on a straight-line basis over the applicable vesting period. For the portion of performance shares subject to the achievement of return on capital, we consider the probability of meeting performance targets when recording compensation expense throughout the performance period.

Income Taxes

INCOME TAXES

Effective Tax Rate

For the three and six months ended 31 March 2026, our consolidated income statements include an income tax expense of $158.7 and $318.1, respectively, compared to an income tax benefit of $505.8 and $365.1 for the comparative prior-year periods. The tax expenses in fiscal year 2026 represent an effective tax rate of 18.0% and 18.3% on the pre-tax income reported for the three and six months ended 31 March 2026, respectively. The tax benefits in fiscal year 2025 represented an effective tax rate of 22.5% and 25.1% on the pre-tax losses reported for the three and six months ended 31 March 2025, respectively. The fiscal year 2025 rates were primarily impacted by pre-tax charges of $2.9 billion for business and asset actions and other prior-year items as further discussed below.

Prior-Year Business and Asset Actions

In fiscal year 2025, we recorded charges related to our decision to exit certain projects and implement other cost-reduction measures as described in Note 4, Business and Asset Actions. These efforts resulted in pre-tax charges of approximately $2.9 billion during the second quarter of fiscal year 2025, which resulted in an overall loss from continuing operations before taxes for the three and six months ended 31 March 2025. The related net tax benefit of these actions, which primarily related to our U.S. operations, totaled $640.6.

The related net tax benefit of $640.6 recorded during the second quarter included a cost of $22.5 to establish reserves for uncertain tax positions related to the deductibility of certain costs in foreign subsidiaries as well as a cost of $13.1 primarily related to lower U.S. tax benefits for foreign-derived income. We also incurred a $41.8 increase in our valuation allowance related to tax benefits for foreign business and asset actions for which we could not recognize an income tax benefit.

Prior-Year Tax Reform Adjustment Related to Deemed Foreign Dividends

During the second quarter of fiscal year 2025, we recorded a net income tax benefit of $34.9 related to our intent to file a refund claim after a review of several U.S. Tax Court cases regarding the U.S. taxation of deemed foreign dividends in the transition year of the U.S. Tax Cuts and Jobs Act (our fiscal year 2018). While we were not a party to these cases, the opinions resulted in a change to our intent to pursue a refund claim. The $34.9 income tax benefit was net of a $67.8 reserve for an uncertain tax position related to the calculation of the refund amount.

Prior-Year Tax on Repatriation of Foreign Earnings

During the second quarter of fiscal year 2025, we recorded an income tax expense of $31.4 related to estimated withholding taxes on foreign earnings that we no longer intended to indefinitely reinvest.

Prior-Year Shareholder Activism-Related Costs

During the first six months of fiscal year 2025, we incurred costs of $61.3 related to a proxy contest led by an activist shareholder as further discussed in Note 17, Supplemental Information. The related net tax benefit recorded during the first half of fiscal year 2025 was $8.4.

Cash Paid for Taxes, Net of Refunds

Income tax payments, net of refunds, were $263.4 and $710.1 for the six months ended 31 March 2026 and 2025, respectively. Fiscal year 2025 included tax payments related to the sale of the LNG business.

Related Party Transactions

We have related party sales to some of our equity affiliates and joint venture partners as well as other income primarily from fees charged for use of Air Products' patents and technology. Sales to and other income from related parties totaled approximately $105 and $190 for the three and six months ended 31 March 2026, respectively, and $70 and $150 for the three and six months ended 31 March 2025, respectively. Sales agreements with related parties include terms that are consistent with those that we believe would have been negotiated at an arm’s length with an independent party. As of 31 March 2026 and 30 September 2025, our consolidated balance sheets included related party trade receivables of approximately $205 and $105, respectively.

Related party debt consists of shareholder loans with our joint venture partner, Lu’An Clean Energy Company. Total debt owed to related parties was $244.3 and $236.5 as of 31 March 2026 and 30 September 2025, respectively. These amounts included $61.0 and $59.0, respectively, in "Current portion of long-term debt" on the consolidated balance sheets.

Prior-Year Shareholder Activism-Related Costs

We recorded shareholder activism-related costs in fiscal year 2025 in connection with a proxy contest that concluded in January 2025 following certification of the election of directors at the 2025 Annual Meeting of Shareholders. Costs of $31.4 ($31.0 after tax) incurred during the second quarter of fiscal year 2025 primarily reflect executive separation costs for our former chief executive officer following the Board of Directors’ appointment of a new chief executive officer, which included a noncash expense of $22.4 related to the acceleration of vesting of share‑based awards and $7.3 in severance and other cash benefits. Costs of $61.3 ($52.9 after tax) incurred during the first six months of fiscal year 2025 also included legal and other professional service fees, as well as incremental proxy solicitation costs related to the 2025 Annual Meeting of Shareholders, which were largely incurred during the first quarter of fiscal year 2025.

Changes in Estimates

Changes in estimates on sale of equipment projects accounted for under the cost incurred input method are recognized as a cumulative adjustment for the inception-to-date effect of such change. We recorded changes to project revenue and cost estimates that unfavorably impacted operating income by approximately $25 and $58 for the three and six months ended 31 March 2026, respectively, and operating loss by approximately $15 and $45 for the three and six months ended 31 March 2025, respectively.

Segment Reporting [Abstract]

Business Segment Information

BUSINESS SEGMENT INFORMATION

We determine our reportable segments based on the manner in which our Chief Operating Decision Maker ("CODM") reviews financial results and allocates resources. The accounting policies applied to our reportable segments are consistent with those used in the preparation of our consolidated financial statements. Our reportable segments are as follows:

•Americas;

•Asia;

•Europe;

•Middle East and India; and

•Corporate and other.

The Americas, Asia, Europe, and Middle East and India segments represent the operations of our regional industrial gases business. Each of these segments qualifies as an individual operating segment and does not reflect the aggregation of multiple operating segments. Corporate and other consists of two operating segments that meet the aggregation criteria under GAAP. All segments also include our share of results from several equity method joint ventures.

Our CODM, who is our Chief Executive Officer, evaluates the performance of our reportable segments through segment operating income. This measure is reviewed regularly in internal management reports and serves as a key metric to monitor actual results against forecasts and prior periods. Segment operating income informs decisions related to resource allocation, including capital investments and employees, and supports strategic planning and long-term project development.

(A)Sales relate to external customers only. All intersegment sales are eliminated in consolidation.

(B)For the regional segments, other segment items primarily include impacts from transactions not directly related to our principal earnings activities, such as technology and royalty income and gains and losses on asset sales. For the Corporate and other segment, other segment items primarily include research and development expense and the net impact of gains and losses on foreign currency transactions.

(C)Operating income (loss) for our reportable segments does not include gains or losses that management does not consider to be indicative of underlying business performance, such as charges related to business and asset actions. Refer below for a reconciliation of total segment operating income to consolidated results.

(D)Segment equity affiliates’ income for the three and six months ended 31 March 2025 excludes a $6.8 impairment charge related to a joint venture in China, which was recorded as part of our business and asset actions during the second quarter of fiscal year 2025. As a result, total segment equity affiliates’ income does not reconcile to equity affiliates’ income for the total company as reported on the consolidated income statements for the three and six months ended 31 March 2025.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The interim consolidated financial statements of Air Products and Chemicals, Inc. and its controlled subsidiaries included herein have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). The accompanying notes are an integral part of these statements.

Certain information normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") has been condensed or omitted as permitted under such rules and regulations. In management’s opinion, the accompanying statements reflect adjustments necessary to fairly present our financial position, results of operations, and cash flows for the periods indicated and contain adequate disclosures to make the information presented not misleading. Adjustments included herein are of a normal, recurring nature unless otherwise disclosed in the notes to the interim consolidated financial statements. Certain prior period information has been reclassified to conform to the current year presentation.

To fully understand the basis of presentation, the interim consolidated financial statements and related notes included herein should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended 30 September 2025 (the "2025 Form 10-K"), which was filed with the SEC on 20 November 2025. Results of operations for interim periods are not necessarily indicative of the results of operations for a full year.

Estimates and Assumptions

Estimates and Assumptions

Preparation of the interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in these statements and the accompanying notes. Actual results could differ from those estimates.

New Accounting Guidance to be Implemented

New Accounting Guidance to be Implemented

Climate-Related Disclosures

In March 2024, the SEC issued Release No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors", which includes final rules for providing annual qualitative and quantitative disclosures regarding certain climate-related topics. As a result of legal challenges, the SEC issued an order in April 2024 to stay the effectiveness of the rules pending the completion of judicial review of the consolidated challenges before the United States Court of Appeals for the Eighth Circuit.

The SEC subsequently announced its withdrawal of its legal defense to such challenges in March 2025; however, the rules have not been formally rescinded by the SEC. In April 2025, the appellate court suspended its proceedings indefinitely and directed the SEC to file a status report outlining its next steps. In response, the SEC stated in July 2025 that it does not intend to revisit the rules and requested the court to rule on the pending petitions.

In September 2025, the appellate court declined the SEC's request and placed the litigation in abeyance, which will remain in effect until the SEC reconsiders the rules by notice-and-comment rulemaking or renews its defense. We continue to monitor these developments.

Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740)—Improvements to Income Tax Disclosures”, to expand income tax disclosures, primarily through disaggregation requirements for the rate reconciliation and income taxes paid. The update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2026, although early adoption is permitted. The amendments should be applied on a prospective basis with a retrospective option. We are evaluating the impact this update will have on our disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires additional disclosures of certain costs and expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization, as well as selling expenses in the notes to the financial statements. In January 2025, the FASB clarified that the update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2028 as well as interim periods thereafter, although early adoption is permitted. The amendments should be applied either prospectively after the effective date or retrospectively to any or all periods presented. We are evaluating the impact this update will have on our disclosures.

Measurement of Credit Losses for Accounts Receivable and Contract Assets

In July 2025, the FASB issued ASU 2025-09, “Measurement of Credit Losses for Accounts Receivable and Contract Assets”, which allows an entity to elect a practical expedient to assume that current conditions as of the balance sheet date do not change when estimating expected credit losses. This update will be effective at the beginning of fiscal year 2027, although early adoption is permitted. The amendments should be applied on a prospective basis. We are evaluating the implications of this update. At this time, we do not expect it will have a material impact on our financial statements.

Accounting for Internal-Use Software

In September 2025, the FASB issued ASU 2025-06, “Targeted Improvements to the Accounting for Internal-Use Software”, which establishes criteria for commencing cost capitalization for software projects. This update will be effective at the beginning of fiscal year 2029, although early adoption is permitted. The amendments can be applied prospectively, retrospectively, or via a modified prospective transition method. We are evaluating the impact this update will have on our financial statements.

Government Grants

In December 2025, the FASB issued ASU 2025-10, “Accounting for Government Grants Received by Business Entities”, which provides guidance on the recognition, measurement, and presentation of government grants. This update will be effective at the beginning of fiscal year 2030, although early adoption is permitted. The amendments can be applied on a modified prospective approach, modified retrospective approach, or a full retrospective approach. We are evaluating the impact this update will have on our financial statements.

Interim Reporting

In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements”. This guidance addresses the form and content of interim financial statements, lists interim disclosures required by other codification topics, and establishes a principle for disclosing events since the end of the last annual reporting period that have a material impact. This update will be effective for interim periods beginning in fiscal year 2029, although early adoption is permitted. The ASU can be applied prospectively or retrospectively. We are evaluating the impact this update will have on our disclosures.

(A)Sales relate to external customers only. All intersegment sales are eliminated in consolidation.

(B)For the regional segments, other segment items primarily include impacts from transactions not directly related to our principal earnings activities, such as technology and royalty income and gains and losses on asset sales. For the Corporate and other segment, other segment items primarily include research and development expense and the net impact of gains and losses on foreign currency transactions.

(C)Operating income (loss) for our reportable segments does not include gains or losses that management does not consider to be indicative of underlying business performance, such as charges related to business and asset actions. Refer below for a reconciliation of total segment operating income to consolidated results.

(D)Segment equity affiliates’ income for the three and six months ended 31 March 2025 excludes a $6.8 impairment charge related to a joint venture in China, which was recorded as part of our business and asset actions during the second quarter of fiscal year 2025. As a result, total segment equity affiliates’ income does not reconcile to equity affiliates’ income for the total company as reported on the consolidated income statements for the three and six months ended 31 March 2025.
