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,” “positioned,” “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, 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 that may affect the availability and terms on which we may obtain financing;

•the ability to 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 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 and our affiliates and joint ventures 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 and divestitures, including our ability to integrate acquisitions and separate divested businesses, respectively;

•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;

3

FORWARD-LOOKING STATEMENTS (CONTINUED)

•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 and 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 success of 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 2023. 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 subsidiaries included herein have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations. In our opinion, the accompanying statements reflect adjustments necessary to fairly present the financial position, results of operations, and cash flows for those 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.

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 2023 (the "2023 Form 10-K"), which was filed with the SEC on 16 November 2023. 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 2023 Form 10-K for a description of major accounting policies. There have been no significant changes to these accounting policies during the first three months of fiscal year 2024.

2. NEW ACCOUNTING GUIDANCE

New Accounting Guidance to be Implemented

Reportable Segment Disclosures

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures". The update includes enhanced disclosures about significant segment expenses and identification of the chief operating decision maker. The update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2025 as well as interim periods thereafter, although early adoption is permitted. The amendments must be applied retrospectively to all prior periods presented. We are evaluating the impact this update will have on our disclosures.

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.

11

3. VARIABLE INTEREST ENTITIES

We are the primary beneficiary of the NEOM Green Hydrogen Company joint venture ("NGHC"), which is 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. We account for a VIE for which we have an equity interest and exercise significant influence but are not the primary beneficiary, such as the Jazan Integrated Gasification and Power Company joint venture ("JIGPC"), as an equity method investment. During the first quarter of fiscal year 2024, we determined that World Energy, LLC ("World Energy") is a VIE for which we have no equity interest and are not the primary beneficiary. Our variable interests in NGHC, JIGPC, and World Energy are further discussed below.

NGHC Joint Venture

The NEOM Green Hydrogen Project (the "NEOM 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. We intend to transport the green ammonia around the world to be dissociated to produce green hydrogen for transportation and industrial markets.

In May 2023, NGHC finalized the $6.7 billion engineering, procurement, and construction ("EPC") agreement with Air Products named as the main contractor and system integrator for the facility. NGHC secured non-recourse project financing of approximately $6.1 billion, which is expected to fund about 73% of the project and will be drawn over the construction period. At the same time, NGHC secured additional non-recourse credit facilities totaling approximately $500 primarily for working capital needs. Under the financing, 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. Borrowings under the financing are reflected net of unamortized discounts and debt issuance costs within "Long-term debt" on our consolidated balance sheets. Principal borrowings totaled $2,129.4 and $1,364.8 as of 31 December 2023 and 30 September 2023, respectively. The increase from 30 September 2023 primarily relates to principal borrowings of approximately $620 as of 31 December 2023 on a 2.00% fixed-rate Saudi Riyal loan facility that matures in November 2040.

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.

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. The carrying value of our investment, including amounts attributable to noncontrolling interests, totaled $2,828.3 and $2,862.2 as of 31 December 2023 and 30 September 2023, respectively. Our loss exposure is limited to our investment in the joint venture.

Our investment 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 finalized an agreement to purchase a sustainable aviation fuel (“SAF”) facility in Paramount, California from World Energy. We determined the acquisition contains an embedded sales-type lease. As a result, we are accounting for the transaction as a financing arrangement and recorded a financing receivable of $210 as of 31 December 2023. We provided the remaining $90 million of financing available under this arrangement to World Energy in January 2024.

At the time of acquisition, we entered into a Master Project Agreement (“MPA”) containing 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. The MPA includes a tolling arrangement whereby we will receive feedstock from and produce renewable fuels for World Energy over a term that will conclude 15 years after onstream of the expansion project with the option to renew for two five-year terms.

During the first quarter of fiscal year 2024, we determined that World Energy is a VIE and our financing receivable represents a variable interest in World Energy. We are not the primary beneficiary as we do not have control over their key operating decisions, including feedstock supply, production of renewable fuels, and negotiating and executing supply agreements with customers. As of 31 December 2023, our maximum exposure to loss is approximately $1.9 billion. This includes project-related spending of $1.3 billion that is primarily capitalized within “Plant and equipment, net” and approximately $350 for open purchase commitments, both of which relate to the SAF expansion project, as well as $300 for our investment in the financing receivables discussed above.

4. REVENUE RECOGNITION

The majority of our revenue is generated from our sale of gas customers within the regional industrial gases segments. We distribute gases 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, natural gas liquefaction, 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 below present our consolidated sales disaggregated by supply mode for each of our reportable segments for the first three months of fiscal years 2024 and 2023. We believe this presentation best depicts the nature, timing, type of customer, and contract terms for our sales.

Total	$1,384.2	$777.8	$791.9	$41.4	$179.4	$3,174.7	100	%

Interest income associated with financing and lease arrangements accounted for approximately 1% of our total consolidated sales during the three months ended 31 December 2023.

14

Remaining Performance Obligations

As of 31 December 2023, the transaction price allocated to remaining performance obligations is estimated to be approximately $27 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 December	30 September
	Balance Sheet Location	2023	2023

(A)We recorded impairment charges related to the Latin America reporting unit ("LASA") in the Americas segment in fiscal years 2017 and 2014. The balance of accumulated impairment losses fluctuates over time due to currency translation.

We review goodwill for impairment annually in the fourth quarter of the fiscal year and whenever events or changes in circumstances indicate that the carrying value of goodwill might not be recoverable.

7. 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 Euros and U.S. Dollars. The maximum remaining term of any forward exchange contract currently outstanding and designated as a cash flow hedge at 31 December 2023 is 2.9 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 Euros and U.S. Dollars.

16

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 December 2023		30 September 2023
	US$ Notional	Years Average Maturity	US$ Notional	Years Average Maturity
Forward Exchange Contracts:
Cash flow hedges	$4,658.6	0.6	$4,463.2	0.7
Net investment hedges	898.5	2.3	864.0	2.5
Not designated	585.1	0.3	709.4	0.3
Total Forward Exchange Contracts	$6,142.2	0.8	$6,036.6	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 €1,930.7 million ($2,131.3) at 31 December 2023 and €1,938.6 million ($2,049.7) at 30 September 2023. The designated foreign currency-denominated debt is presented within "Long-term debt" on the 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 December 2023, 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, Indian Rupee, and Chilean Peso.

21

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 $69.6 and $94.2 as of 31 December 2023 and 30 September 2023, 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 $107.5 and $345.0 as of 31 December 2023 and 30 September 2023, respectively. No financial institution is required to post collateral at this time, as all have credit ratings at or above threshold.

8. 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:

Short-term Investments

Short-term investments primarily include time deposits with original maturities greater than three months and less than one year. We estimated the fair value of our short-term investments, which approximates carrying value as of the balance sheet date, using Level 2 inputs within the fair value hierarchy. Level 2 measurements were based on current interest rates for similar investments with comparable credit risk and time to maturity.

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 7, 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 amount of service costs capitalized in the first three months of fiscal years 2024 and 2023 were not material. The non-service related impacts are presented outside operating income within "Other non-operating income (expense), net."

For the three months ended 31 December 2023 and 2022, our cash contributions to funded pension plans and benefit payments under unfunded pension plans were $12.0 and $8.0, respectively. Total contributions for fiscal year 2024 are expected to be approximately $35 to $45. During fiscal year 2023, total contributions were $32.6.

During the three months ended 31 December 2023 and 2022, we recognized actuarial gain amortization of $0.1 and $0.6, respectively, for our other postretirement benefits plan.

10. 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.

In September 2010, the Brazilian Administrative Council for Economic Defense ("CADE") issued a decision against our Brazilian subsidiary, Air Products Brasil Ltda., and several other Brazilian industrial gas companies for alleged anticompetitive activities. CADE imposed a civil fine of R$179.2 million (approximately $37 at 31 December 2023) on Air Products Brasil Ltda. This fine was based on a recommendation by a unit of the Brazilian Ministry of Justice, following an investigation beginning in 2003, which alleged violation of competition laws with respect to the sale of industrial and medical gases. The fines are based on a percentage of our total revenue in Brazil in 2003.

We have denied the allegations made by the authorities and filed an appeal in October 2010 with the Brazilian courts. On 6 May 2014, our appeal was granted and the fine against Air Products Brasil Ltda. was dismissed. CADE has appealed that ruling and the matter remains pending. We, with advice of our outside legal counsel, have assessed the status of this matter and have concluded that, although an adverse final judgment after exhausting all appeals is possible, such a judgment is not probable. As a result, no provision has been made in the consolidated financial statements. In the event of an adverse final judgment, we estimate the maximum possible loss to be the full amount of the fine of R$179.2 million (approximately $37 at 31 December 2023) plus interest accrued thereon until final disposition of the proceedings.

24

Additionally, in April 2023, we received a favorable ruling from a Texas state court in litigation involving disputed energy management charges related to Winter Storm Uri, a severe winter weather storm that impacted the U.S. Gulf Coast in February 2021. The ruling is subject to appeal and had no impact on our consolidated financial statements for the three months ended 31 December 2023.

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), Resource Conservation and Recovery Act ("RCRA"), and similar state environmental laws relating to the designation of certain sites for investigation or remediation. Presently, there are 27 sites on which a final settlement or remediation has not been achieved where we, usually along with others, have been designated a potentially responsible party by environmental authorities or are otherwise engaged in investigation or remediation, including cleanup activity at certain of our current and former 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. The consolidated balance sheets at 31 December 2023 and 30 September 2023 included an accrual of $63.3 and $64.5, respectively, primarily as part of other noncurrent liabilities. The environmental liabilities will be paid over a period of up to 27 years. We estimate the exposure for environmental loss contingencies to range from $63 to a reasonably possible upper exposure of $77 as of 31 December 2023.

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 the inherent uncertainties related to environmental exposures, 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

At 31 December 2023, $36.7 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. The review was completed in conjunction with requirements to maintain financial assurance per the consent order issued by the FDEP discussed below. Based on our review, we expect ongoing activities to continue for 27 years. 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 2020. There have been no significant changes to the estimated exposure range related to the Pace facility since fiscal year 2020.

25

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 suitable to more quickly and effectively remediate groundwater. Based on assessment results, we completed a focused feasibility study that has identified alternative approaches that may more effectively remove contaminants. We continue to review alternative remedial approaches with the FDEP and completed additional field work during 2021 to support the design of an improved groundwater recovery network with the objective of targeting areas of higher contaminant concentration and avoiding 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 initiated in fiscal year 2023 with construction expected to begin in fiscal year 2025. In fiscal year 2025, we expect to connect groundwater recovery wells and ancillary equipment to the existing groundwater recovery system. Further, we expect additional future capital expenditures to consider the extended time horizon for remediation at the site.

Piedmont

At 31 December 2023, $4.1 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 Health and Environmental Control ("SCDHEC") to address both contaminated soil and groundwater. Numerous areas of soil contamination have been addressed, and contaminated groundwater is being recovered and treated. The SCDHEC 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 2029. Thereafter, we expect this site to go into a state of monitored natural attenuation through 2047. 

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. There have been no significant changes to the estimated exposure.

Pasadena

At 31 December 2023, $10.4 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 ("PUI") 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, as required, impacted soils, investigating groundwater west of the former PUI facility, 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. In 2012, we estimated the total exposure at this site to be $13. There have been no significant changes to the estimated exposure.

11. SHARE-BASED COMPENSATION

Our outstanding share-based compensation programs include deferred stock units and stock options. During the three months ended 31 December 2023, we granted market-based and time-based deferred stock units. Under all programs, the terms of the awards are fixed at the grant date. We issue shares from treasury stock upon the payout of deferred stock units and the exercise of stock options. As of 31 December 2023, there were 1.0 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
	31 December
	2023	2022
Before-tax share-based compensation cost	$13.6	$16.9
Income tax benefit	(3.3)	(4.1)
After-tax share-based compensation cost	$10.3	$12.8

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 three months of fiscal years 2024 and 2023 was not material.

Deferred Stock Units

During the three months ended 31 December 2023, we granted 102,120 market-based deferred stock units. The market-based deferred stock units are earned over the performance period beginning 1 October 2023 and ending 30 September 2026, conditioned on the level of our total shareholder return in relation to the S&P 500 Index over the three-year performance period.

The market-based deferred stock units had an estimated grant-date fair value of $302.10 per unit, which was estimated using a Monte Carlo simulation model. 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. We generally expense the grant-date fair value of these awards on a straight-line basis over the vesting period. The calculation of the fair value of market-based deferred stock units used the following assumptions:

Expected volatility	25.0	%
Risk-free interest rate	4.3	%
Expected dividend yield	2.6	%

In addition, during the three months ended 31 December 2023, we granted 132,317 time-based deferred stock units at a weighted average grant-date fair value of $273.02.

14. 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 $95 and $80 for the three months ended 31 December 2023 and 2022, 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 December 2023 and 30 September 2023, our consolidated balance sheets included related party trade receivables of approximately $90 and $80, respectively.

Total debt owed to related parties was $294.8 and $328.3 as of 31 December 2023 and 30 September 2023, respectively, of which $136.9 and $177.6, respectively, was reflected within "Current portion of long-term debt" on our consolidated balance sheets. Our related party debt primarily includes a loan with our joint venture partner, Lu’An Clean Energy Company.

Uzbekistan Asset Purchase

On 25 May 2023, we entered into an investment agreement with the Government of the Republic of Uzbekistan and Uzbekneftegaz JSC (“UNG”) to purchase a natural gas-to-syngas processing facility in Qashqadaryo Province, Uzbekistan, for $1 billion. Under the agreement, Air Products will acquire, own, and operate the facility and supply all offtake products to UNG under a 15-year on-site contract, with UNG supplying the feedstock natural gas and utilities. We are accounting for the transaction as a financing arrangement because UNG has the right to reacquire the facility at the end of the contract term. Accordingly, progress payments of approximately $910, of which $100 was paid during the first quarter of fiscal year 2024, are reflected within "Financing receivables" on our consolidated balance sheet as of 31 December 2023.

29

Accrual for Business and Asset Actions

In fiscal year 2023, we recognized an expense of $27.0 for severance and other benefits associated with position eliminations and restructuring of certain organizations globally. The charge was not recorded in segment results. The table below reconciles the charge to the carrying amount of the accrual included within "Payables and accrued liabilities" on our consolidated balance sheets as of 31 December 2023:

Fiscal year 2023 charge	$27.0
Cash payments	(6.8)
Currency translation adjustment	(0.4)
Accrual as of 30 September 2023	$19.8
Cash payments	(3.4)
Currency translation adjustment	0.4
Accrual as of 31 December 2023	$16.8

Debt

Third-party long-term debt was $11,715.4 and $9,280.6 as of 31 December 2023 and 30 September 2023, respectively. The increase from 30 September 2023 was primarily due to the issuance of commercial paper as well as additional borrowings under the project financing associated with the NEOM Green Hydrogen Project as discussed in Note 3, Variable Interest Entities. As of 31 December 2023, we classified the outstanding commercial paper, which totaled approximately $1.3 billion, as well as our 3.35% Senior Note of $400 maturing in July 2024 as long-term debt as we have the ability to refinance the debt under our $2.75 billion revolving credit agreement (the “2021 Credit Agreement”) maturing in 2026. Our current intent is to refinance this debt via the U.S. public debt market.

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 estimates that unfavorably impacted operating income by approximately $30 and $25 for the three months ended 31 December 2023 and 2022, respectively.

Income Taxes

Our effective tax rate was 17.9% and 18.9% for the three months ended 31 December 2023 and 2022, respectively.

Income tax payments, net of refunds, were $90.1 and $88.5 for the three months ended 31 December 2023 and 2022, respectively.

This Management’s Discussion and Analysis contains “forward-looking statements” within the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, including statements about business outlook. 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, including, 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 2023 (the "2023 Form 10-K"), which was filed with the SEC on 16 November 2023.

This discussion should be read in conjunction with the interim consolidated financial statements and the accompanying notes contained in this Quarterly Report on Form 10-Q. Unless otherwise stated, financial information is presented in millions of U.S. Dollars, except for per share data. Financial information is presented on a continuing operations basis.

The financial measures discussed below are presented in accordance with U.S. generally accepted accounting principles ("GAAP"), except as noted. We present certain financial measures on an "adjusted", or "non-GAAP", basis because we believe such measures, when viewed together with financial results computed in accordance with GAAP, provide a more complete understanding of the factors and trends affecting our historical financial performance. For each non-GAAP financial measure, including adjusted diluted earnings per share ("EPS"), adjusted EBITDA, adjusted EBITDA margin, 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 explanations regarding the use of non-GAAP measures are presented under the “Reconciliations of Non-GAAP Financial Measures” section beginning on page 40.

Comparisons included in the discussion that follows are for the first quarter of fiscal year 2024 versus ("vs.") the first quarter of fiscal year 2023. The disclosures provided in this Quarterly Report on Form 10-Q are complementary to those made in our 2023 Form 10-K.

For information concerning activity with our related parties, refer to Note 14, Supplemental Information, to the consolidated financial statements.

Sales

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

Volume	3	%
Price	1	%
Energy cost pass-through to customers	(11	%)
Currency	1	%
Total Consolidated Sales Change	(6	%)

Sales of $2,997.4 decreased 6%, or $177.3, as lower energy cost pass-through to customers of 11% was partially offset by higher volumes of 3%, higher pricing of 1%, and a favorable currency impact of 1%. Lower natural gas prices in the Americas and Europe segments drove the lower energy cost pass-through to our on-site customers. The volume improvement was primarily attributable to strong demand for hydrogen in our on-site business, which was partially offset by weaker demand for helium in our merchant business.

Cost of Sales and Gross Margin

Cost of sales of $2,067.2 decreased 9%, or $205.1, due to lower energy cost pass-through to customers of $340, partially offset by higher costs associated with sales volumes of $78, an unfavorable impact from currency of $30, and higher other costs of $27. The higher costs were driven by planned maintenance, higher depreciation expense, and inflation, partially offset by lower power costs in our merchant business across most regions. Gross margin of 31.0% increased 260 bp from 28.4% in the prior year primarily due to lower energy cost pass-through to customers, which favorably impacted margin by about 300 bp.

Selling and Administrative Expense

Selling and administrative expense of $238.4 increased 2%, or $4.0, primarily due to additional costs to support growth and labor inflation. Selling and administrative expense as a percentage of sales increased to 8.0% from 7.4% in the prior year.

Research and Development Expense

Research and development expense of $25.7 increased 5%, or $1.3. Research and development expense as a percentage of sales increased to 0.9% from 0.8% in the prior year.

Other Income (Expense), Net

Other income of $0.8 decreased 90%, or $7.6, primarily due to an unfavorable foreign exchange impact from the devaluation of the Argentine peso.

35

Operating Income and Operating Margin

Operating income of $666.9 increased 2%, or $14.9, as positive pricing, net of power and fuel costs, of $41 and higher volumes of $30 were partially offset by higher costs of $56. The higher costs were driven by planned maintenance, labor inflation, and higher depreciation expense. Operating margin of 22.2% increased 170 bp from 20.5% in the prior year primarily due to lower energy cost pass-through to customers, which positively impacted margin by about 200 basis points, as well as our pricing actions, partially offset by higher costs.

Equity Affiliates' Income

Equity affiliates' income of $158.4 increased 44%, or $48.4, primarily due to a higher contribution from the JIGPC joint venture, which completed the second phase of the asset purchase associated with the Jazan gasification and power project in January 2023, as well as higher income from our affiliate in Mexico.

Interest Expense

	Three Months Ended

	2023	2022
Interest incurred	$108.6	$56.3
Less: Capitalized interest	55.1	15.1
Interest expense	$53.5	$41.2

Interest incurred increased 93%, or $52.3, driven by a higher debt balance, including borrowings on project financing for the NEOM Green Hydrogen Project as well as the multi-currency green bonds that were issued during the second quarter of fiscal year 2023 to finance projects that are expected to have environmental benefits as defined under our Green Finance Framework. Capitalized interest increased $40.0 due to a higher carrying value of projects under construction, including the NEOM Green Hydrogen Project.

Other Non-Operating Income (Expense), Net

Other non-operating expense of $14.8 increased $14.2, primarily due to higher non-service pension costs as well as lower interest income on cash and cash items. The lower interest income was attributable to a lower balance of time deposits and short-term treasury securities.

Net Income and Net Income Margin

Net income of $621.6 increased 6%, or $37.8, primarily due to higher equity affiliates' income, favorable pricing, and higher volumes, partially offset by higher costs. Net income margin of 20.7% increased 230 bp from 18.4% in the prior year due to the factors noted above as well as lower energy cost pass-through to customers, which positively impacted margin by about 200 bp.

Adjusted EBITDA and Adjusted EBITDA Margin

Adjusted EBITDA of $1,174.5 increased 8%, or $91.0, primarily due to higher equity affiliates' income, higher volumes, and favorable pricing, partially offset by higher costs. Adjusted EBITDA margin of 39.2% increased 510 bp from 34.1% in the prior year due to the factors noted above as well as lower energy cost pass-through to customers, which positively impacted margin by about 400 bp.

Effective Tax Rate

The effective tax rate equals the income tax provision divided by income before taxes. Equity affiliates' income is primarily included net of income taxes within income before taxes on our consolidated income statements.

Our effective tax rate was 17.9% and 18.9% for the three months ended 31 December 2023 and 2022, respectively. The current year rate was lower primarily due to earning a greater share of income in jurisdictions with lower tax rates and higher equity affiliates' income. Additionally, we released certain foreign unrecognized tax benefits during the first quarter of fiscal year 2024 upon expiration of the statute of limitations for uncertain tax positions taken in prior years. These impacts were partially offset by lower excess tax benefits on share-based compensation in the first quarter of fiscal year 2024.

Our adjusted effective tax rate, which excludes the impact of the non-service components of net periodic cost for our defined benefit pension plans, was 18.1% and 19.1% for the three months ended 31 December 2023 and 2022, respectively.

Sales of $793.8 increased 2%, or $16.0, due to higher energy cost pass-through to customers of 2% and higher pricing of 1%, partially offset by an unfavorable impact from currency of 1%. Overall volumes were flat as higher volumes in our on-site business, including contributions from several new industrial gas plants, were offset by weak economic growth in China and lower demand for helium.

Operating income of $211.2 decreased 10%, or $24.7, primarily due to negative volume mix of $13 and higher costs of $7, including higher maintenance costs and labor inflation. Operating margin of 26.6% decreased 370 bp from 30.3% in the prior year.

Equity affiliates’ income of $4.2 decreased 43%, or $3.2, driven by higher maintenance expense for one of our affiliates in China.

Total Europe Sales Change	(8	%)

Sales of $731.2 decreased 8%, or $60.7, due to lower energy cost pass-through to customers of 20%, which was driven by lower natural gas prices, and lower pricing of 2%. These impacts were partially offset by higher volumes of 9% and a favorable impact from currency of 5%. The volume improvement was driven by a facility in Uzbekistan that we acquired in the third quarter of fiscal year 2023. Currency positively impacted sales due to the weakening of the U.S. Dollar against the Euro.

Operating income of $197.6 increased 36%, or $51.8, primarily due to higher volumes of $51, a net pricing impact of $13 due to lower power costs, and favorable currency of $8, partially offset by higher costs of $20. The higher costs were driven by labor inflation and higher costs for planned maintenance. Operating margin of 27.0% increased 860 bp from 18.4% in the prior year due to the factors noted above as well as lower energy cost pass-through to customers, which positively impacted margin by about 350 bp.

Equity affiliates’ income of $20.7 increased 17%, or $3.0, driven by affiliates in Italy and South Africa.

RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES

(Millions of U.S. Dollars unless otherwise indicated, except for per share data)

We present certain financial measures, other than in accordance with U.S. generally accepted accounting principles ("GAAP"), on an "adjusted" or "non-GAAP" basis. On a consolidated basis, these measures include adjusted diluted earnings per share ("EPS"), adjusted EBITDA, adjusted EBITDA margin, the adjusted effective tax rate, and capital expenditures. On a segment basis, these measures include adjusted EBITDA and adjusted EBITDA margin. In addition to these measures, we also present certain supplemental non-GAAP financial measures to help the reader understand the impact that certain disclosed items, or "non-GAAP adjustments," have on the calculation of our adjusted diluted EPS. For each non-GAAP financial measure, we present a reconciliation to the most directly comparable financial measure calculated in accordance with GAAP.

In many cases, non-GAAP financial measures are determined by adjusting the most directly comparable GAAP measure to exclude non-GAAP adjustments that we believe are not representative of our underlying business performance. For example, we exclude the impact of the non-service components of net periodic benefit/cost for our defined benefit pension plans. 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. We may also exclude certain expenses associated with cost reduction actions, impairment charges, and gains on disclosed transactions. The reader should be aware that we may recognize similar losses or gains in the future.

When applicable, the tax impact of our pre-tax non-GAAP adjustments reflects the expected current and deferred income tax impact of our non-GAAP adjustments. These tax impacts are primarily driven by the statutory tax rate of the various relevant jurisdictions and the taxability of the adjustments in those jurisdictions.

We provide these non-GAAP financial measures to allow investors, potential investors, securities analysts, and others to evaluate the performance of our business in the same manner as our management. We believe these measures, when viewed together with financial results computed in accordance with GAAP, provide a more complete understanding of the factors and trends affecting our historical financial performance and projected future results. However, we caution readers not to consider these measures in isolation or as a substitute for the most directly comparable measures calculated in accordance with GAAP. Readers should also consider the limitations associated with these non-GAAP financial measures, including the potential lack of comparability of these measures from one company to another.

ADJUSTED DILUTED EPS

The table below provides a reconciliation to the most directly comparable GAAP measure for each of the major components used to calculate adjusted diluted EPS from continuing operations, which we view as a key performance metric. In periods that we have non-GAAP adjustments, we believe it is important for the reader to understand the per share impact of each such adjustment because management does not consider these impacts when evaluating underlying business performance. Per share impacts are calculated independently and may not sum to total diluted EPS and total adjusted diluted EPS due to rounding.

ADJUSTED EBITDA AND ADJUSTED EBITDA MARGIN

We define adjusted EBITDA as net income less income from discontinued operations, net of tax, and excluding non-GAAP adjustments, which we do not believe to be indicative of underlying business trends, before interest expense, other non-operating income (expense), net, income tax provision, and depreciation and amortization expense. Adjusted EBITDA and adjusted EBITDA margin provide useful metrics for management to assess operating performance. Margins are calculated independently for each period by dividing each line item by consolidated sales for the respective period and may not sum to total margin due to rounding.

The table below presents consolidated sales and a reconciliation of net income on a GAAP basis to adjusted EBITDA and net income margin on a GAAP basis to adjusted EBITDA margin:

CAPITAL EXPENDITURES

Capital expenditures is a non-GAAP financial measure that we define as the sum of cash flows 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 on our consolidated statements of cash flows. Additionally, we adjust additions to plant and equipment to exclude NEOM Green Hydrogen Company (“NGHC”) expenditures funded by the joint venture's non-recourse project financing as well as our partners’ equity contributions to arrive at a measure that we believe is more representative of our investment activities. Substantially all the funding we provide to NGHC is limited for use by the venture for capital expenditures.

A reconciliation of cash used for investing activities to our reported capital expenditures is provided below:

LIQUIDITY AND CAPITAL RESOURCES

We believe we have sufficient cash, cash flows from operations, and funding sources to meet our liquidity needs. As further discussed in the "Cash Flows From Financing Activities" section below, we have the ability 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 December 2023, we had $1,852.1 of foreign cash and cash items compared to total cash and cash items of $1,962.6. We do not expect that a significant portion of the earnings of our foreign subsidiaries and affiliates will be subject to U.S. income tax upon repatriation to the U.S. Depending on the country in which the subsidiaries and affiliates reside, the repatriation of these earnings may be subject to foreign withholding and other taxes. However, since we have significant current investment plans outside the U.S., it is our intent to permanently 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	(369.6)	(337.6)
Cash Provided by Operating Activities	$626.6	$719.3

For the first three months of fiscal year 2024, cash provided by operating activities was $626.6. The working capital accounts were a use of cash of $369.6, primarily driven by $268.5 from payables and accrued liabilities, $64.5 from other receivables, and $48.6 from inventories. The use of cash within payables and accrued liabilities primarily resulted from payments for incentive compensation under the fiscal year 2023 plan, a reduction of customer advances for sale of equipment projects as we recognized revenue, and a reduction of liabilities associated with accrued utilities. The use of cash within other receivables primarily relates to the payment of value added taxes incurred in the construction of our larger projects for which we will claim a refund in the near term. The use of cash within inventories primarily relates to purchases of helium.

For the first three months of fiscal year 2023, cash provided by operating activities was $719.3. Distributed earnings of equity method investments reflect distributions in excess of earnings for the period of $17.2. Other adjustments of $99.0 primarily included adjustments for noncash currency impacts of intercompany balances. The working capital accounts were a use of cash of $337.6, primarily driven by $257.6 from payables and accrued liabilities and $102.8 from inventory. The use of cash within payables and accrued liabilities primarily resulted from the decrease in value of derivatives that hedge intercompany loans, payments for incentive compensation under the fiscal year 2022 plan and a reduction of liabilities associated with the purchase of natural gas.

	Three Months Ended
	31 December
	2023	2022
Additions to plant and equipment, including long-term deposits	$1,445.5	$834.2
Investment in financing receivables	301.8	—
NGHC expenditures not funded by Air Products' equity(A)	(361.6)	(109.7)
Capital Expenditures	$1,385.7	$724.5

(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.

Capital expenditures for the first three months of fiscal year 2024 totaled $1,385.7 compared to $724.5 for the first three months of fiscal year 2023. The investment in financing receivables of $301.8 primarily reflects payments associated with the purchase of renewable fuel assets from World Energy as well as the purchase of a natural gas-to-syngas processing facility in Uzbekistan. Refer to Note 3, Variable Interest Entities, and Note 18, Supplemental Information, to the consolidated financial statements, respectively, for additional information.

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 we are 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.

We continue to expect capital expenditures for fiscal year 2024 to be approximately $5.0 billion to $5.5 billion.

Cash Flows From Financing Activities

	Three Months Ended
	31 December
	2023	2022
Long-term debt proceeds	$810.4	$476.3
Payments on long-term debt	(54.8)	(195.9)
Net increase (decrease) in commercial paper and short-term borrowings	1,020.9	(4.1)
Dividends paid to shareholders	(388.9)	(359.4)
Proceeds from stock option exercises	5.3	14.0
Investments by noncontrolling interests	34.5	—
Other financing activities	(64.6)	(16.5)
Cash Provided by (Used for) Financing Activities	$1,362.8	($85.6)

For the first three months of fiscal year 2024, cash provided by financing activities was $1,362.8. The source of cash was primarily driven by net increase in commercial paper and short-term borrowings of $1,020.9 and long-term debt proceeds of $810.4, partially offset by dividend payments to shareholders of $388.9 and payments on long-term debt of $54.8.

For the first three months of fiscal year 2023, cash used for financing activities was $85.6. The use of cash was primarily driven by dividend payments to shareholders of $359.4 and payments on long-term debt of $195.9 partially offset by long-term debt proceeds of $476.3.

Financing and Capital Structure

Debt

Total debt increased from $10,305.8 as of 30 September 2023 to $12,107.7 as of 31 December 2023. The increase from 30 September 2023 was primarily due to the issuance of commercial paper as well as additional 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. As of 31 December 2023, we classified our outstanding commercial paper, which totaled approximately $1.3 billion, as well as our 3.35% Senior Note of $400 maturing in July 2024 as long-term debt as we have the ability to refinance the debt under our $2.75 billion revolving credit agreement (the “2021 Credit Agreement”), which is further discussed below. Our current intent is to refinance this debt via the U.S. public debt market.

Total debt includes related party debt of $294.8 and $328.3 as of 31 December 2023 and 30 September 2023, respectively.

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 December 2023, we were in compliance with all of the financial and other covenants under our debt agreements.

2021 Credit Agreement

We have a five-year $2.75 billion revolving credit agreement maturing 31 March 2026 with a syndicate of banks (the “2021 Credit Agreement”), under which senior unsecured debt is available to us and certain of our subsidiaries. The 2021 Credit Agreement provides a source of liquidity and supports our commercial paper program. No borrowings were outstanding under the 2021 Credit Agreement as of 31 December 2023. At this time, we do not expect to borrow from the facility.

The only financial covenant in the 2021 Credit Agreement is a maximum ratio of total debt to total capitalization (equal to total debt plus total equity) not to exceed 70%. The 2021 Credit Agreement defines total debt as the aggregate principal amount of all indebtedness, excluding limited recourse debt of any project financed subsidiary. Accordingly, this calculation does not consider borrowings associated with NGHC. Total debt to total capitalization was 38.7% and 36.6% as of 31 December 2023 and 30 September 2023, respectively.

48

Foreign Credit Facilities

We also have credit facilities available to certain of our foreign subsidiaries totaling $1,611.4, of which $1,091.1 was borrowed and outstanding as of 31 December 2023. The amount borrowed and outstanding as of 30 September 2023 was $1,041.4.

NEOM Green Hydrogen Project Financing

In May 2023, NGHC secured non-recourse project financing of approximately $6.1 billion, which is expected to fund approximately 73% of the NEOM Green Hydrogen Project and will be drawn over the construction period. At the same time, NGHC secured additional non-recourse credit facilities totaling approximately $500 primarily for working capital needs. The joint venture had borrowed $2.1 billion and $1.4 billion of the available financing as of 31 December 2023 and 30 September 2023, respectively. Refer to Note 3, Variable Interest Entities, to the consolidated financial statements for additional information.

Dividends

The Board of Directors determines whether to declare cash dividends on our common stock and the timing and amount based on financial condition and other factors it deems relevant. Dividends are paid quarterly, usually during the sixth week after the close of the fiscal quarter. On 15 November 2023, the Board of Directors declared a quarterly dividend of $1.75 per share that is payable on 12 February 2024 to shareholders of record at the close of business on 2 January 2024.

In January 2024, the Board of Directors increased the quarterly dividend to $1.77 per share, representing our 42nd consecutive year of dividend increases. The new dividend was declared on 25 January 2024 and is payable on 13 May 2024 to shareholders of record at the close of business on 1 April 2024.

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 9, 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
	31 December
	2023	2022
Service cost	$5.2	$6.0
Non-service cost	24.9	19.5
Other	0.1	0.3
Net Periodic Cost	$30.2	$25.8

Net periodic cost was $30.2 and $25.8 for the three months ended 31 December 2023 and 2022, respectively. The increased costs versus the prior year were primarily attributable to non-service costs, which were driven by lower expected returns on plan assets due to a smaller beginning balance of plan assets and higher interest cost, partially offset by 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 three months of fiscal years 2024 and 2023 was not material.

49

Company Contributions

Management considers various factors when making pension funding decisions, including tax, cash flow, and regulatory implications. For the three months ended 31 December 2023 and 2022, our cash contributions to funded pension plans and benefit payments for unfunded pension plans were $12.0 and $8.0, respectively.

Total contributions for fiscal year 2024 are expected to be approximately $35 to $45. During fiscal year 2023, total contributions were $32.6.

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 2023 Form 10-K. There were no changes to our accounting policies during the first three months of fiscal year 2024.

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 three months of fiscal year 2024, we recorded changes to project cost estimates on certain sale of equipment projects that are accounted for under the cost incurred input method. Accordingly, we recorded a cumulative effect adjustment that unfavorably impacted operating income by approximately $30 for the three months ended 31 December 2023. There were no other changes to our estimates during the first three months of fiscal year 2024 that had a significant impact on our financial condition, change in financial condition, liquidity, or results of operations.

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 2023 Form 10-K.

Our net financial instrument position increased from a liability of $8,990.8 at 30 September 2023 to a liability of $11,662.0 at 31 December 2023. The increase was primarily due to the issuance of commercial paper as well as additional 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. As of 31 December 2023, we classified the outstanding commercial paper, which totaled approximately $1.3 billion, as long-term debt as we have the ability to refinance the debt under our $2.75 billion revolving credit agreement maturing in 2026. Our current intent is to refinance this debt via the U.S. public debt market.

Interest Rate Risk

Our debt portfolio as of 31 December 2023, including the effect of currency and interest rate swap agreements, was composed of 73% fixed-rate debt and 27% variable-rate debt. Our debt portfolio as of 30 September 2023, including the effect of currency and interest rate swap agreements, was composed of 80% fixed-rate debt and 20% variable-rate debt. The increase in variable-rate debt was primarily driven by commercial paper of approximately $1.3 billion that was classified as long-term debt as of 31 December 2023.

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 December 2023, with all other variables held constant. A 100 bp increase in market interest rates would result in a decrease of $879 and $728 in the net liability position of financial instruments at 31 December 2023 and 30 September 2023, respectively. A 100 bp decrease in market interest rates would result in an increase of $1,030 and $845 in the net liability position of financial instruments at 31 December 2023 and 30 September 2023, respectively.

Based on the variable-rate debt included in our debt portfolio, including the interest rate swap agreements, a 100 bp increase in interest rates would result in an additional $33 and $21 of interest incurred per year at 31 December 2023 and 30 September 2023, respectively. A 100 bp decline in interest rates would lower interest incurred by $33 and $21 per year at 31 December 2023 and 30 September 2023, respectively.

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 December 2023, 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 $369 and $308 in the net liability position of financial instruments at 31 December 2023 and 30 September 2023, respectively.

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 December 2023. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of 31 December 2023, 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 December 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

51

PART II—OTHER INFORMATION

Item 5. Other Information

(h)Non-Competition. During your employment by the Company and, unless you are an Excluded Service Provider, during the Restricted Period, you agree that you will not Provide Services to any Person, other than the Company, that engages in or is preparing to engage in the Business of the Company within the Restricted Area, unless (i) such other Person also engages in lines of business that are separate, distinct and divisible from the Business of the Company, (ii) you do not Provide Services, Confidential Information or strategy to the Business of the Company conducted by such other Person, and (iii) you do not attend meetings where the Business of the Company conducted by such other Person is discussed or where you could, even inadvertently, disclose Confidential Information. Your passive ownership of not more than one percent (1%) of the capital stock or other ownership or equity interest, or voting power, in a public company, registered under the Securities Exchange Act of 1934, as amended, shall not be deemed to be a violation of this paragraph. For the avoidance of doubt, if you are an Excluded Service Provider, as described in Section 1(l) below (Grantees in California and Certain Other Jurisdictions), this Section 1(h) applies to you while you are providing services to the Company and does not apply to you during the Restricted Period.

(j)Tolling. If you violate any of the terms of the Restrictive Covenant obligations articulated herein, the obligation at issue will run from the first date on which you cease to be in violation of such obligation.

(k)Successors and Assigns. The Award Agreement (including this Paragraph 1) shall inure to the benefit of the successors and assigns of the Company.

If your employment by the Company and all its affiliates terminates on or after 1 December 2024, but during the Deferral Period, other than due to death, Disability, Retirement or a termination by the Company without Cause, all of your Performance Shares will be automatically forfeited in their entirety. For purposes of this Award Agreement, (i) a termination without Cause by the Company during the Deferral Period shall be referred to as an “Involuntary Termination,” and (ii) Cause shall have the meaning set forth in the Plan, provided that if the administrator of the Air Products and Chemicals, Inc. Executive Separation Program (the “Program”) determines that you are eligible for the benefits of the Program, Cause shall have the meaning set forth in the Program.

a.Death or Disability. If your employment by the Company and all its affiliates is terminated during the Deferral Period (including before 1 December 2024), due to death or Disability, you will vest in a pro-rata portion of your earned Performance Shares, based on actual financial performance, as determined by the Administrator in its sole discretion, (which portion in each case shall be based on the number of full months you worked during the Performance Period before your termination of employment divided by 36) and your remaining Performance Shares will be forfeited. If your employment by the Company and all its affiliates terminates at any time during the Deferral Period (including before 1 December 2024) due to death or Disability, payment in respect of earned Performance Shares that have not been forfeited and of related Dividend Equivalents shall be made, as soon as practicable following the end of the Deferral Period (but in no event later than 60 days thereafter), to you, or, in the event of death, your Designated Beneficiary or, if none, your legal representative.

b.Retirement. If your employment by the Company and all its affiliates is terminated on or after 1 December 2024, but during the Deferral Period, due to Retirement, you will vest in a pro-rata portion of your earned Performance Shres, based on actual financial performance, as determined by the Administrator in its sole discretion, (which portion in each case shall be based on the number of full months you worked during the Performance Period before your termination of employment divided by 36) and your remaining Performance Shares will be forfeited. In the event of your termination of employment due to Retirement on or after 1 December 2024 and prior to the end of the Deferral Period, payment in respect of the Performance Shares due to you and of related Dividend Equivalents shall be made as soon as administratively practical following the end of the Deferral Period (but in no event later than 60 days thereafter).

c.Involuntary Termination. If your employment is terminated at any time during the Deferral Period (including before 1 December 2024) due to Involuntary Termination and you execute a general release of claims in favor of the Company within 50 days following your termination in a form satisfactory to the Administrator (a “Release”), you will vest in a pro-rata portion of your earned Performance Shares, based on actual financial performance, as determined by the Administrator in its sole discretion, (which portion shall be based on the number of full months you worked during the Performance Period before your termination of employment divided by 36) and all of your remaining Performance Shares will be forfeited. If you do not execute a Release, all of your Performance Shares will be automatically forfeited in their entirety. With respect to an Involuntary Termination that also meets the definition of Retirement: (i) if services to the Company are terminated before 1 December 2024, such termination of employment shall be deemed to be, and shall be treated as, an Involuntary Separation for purposes of this Award Agreement; and (ii) if services to the Company are terminated on or after 1 December 2024 and prior to the end of the Deferral Period, such termination of employment shall be deemed to be, and shall be treated as, a Retirement for purposes of this Award Agreement. If your employment by the Company and all its affiliates terminates at any time during the Deferral Period due to Involuntary Termination, payment in respect of Performance Shares that have not been forfeited and of related Dividend Equivalents shall be made as soon as administratively practical following the end of the Deferral Period (but in no event later than 60 days thereafter).

5.Notwithstanding anything to the contrary above, if your employment by the Company and its affiliates is terminated and such termination constitutes a “Termination of Employment” within the meaning of the Program and the administrator of the Program determines you are entitled to the benefits of the Program, your outstanding Awards under this Agreement shall be treated in accordance with the Program.

6.Recoupment and Forfeiture. This award, and any proceeds hereunder, shall be subject to the terms of the Air Products and Chemicals, Inc. Compensation Recoupment Policy and Air Products and Chemicals, Inc. Supplemental Executive Officer Recoupment Policy (each a “Policy”), each as may be amended from time to time. By accepting this award, you acknowledge that this award, and proceeds hereunder, are subject to reimbursement, repayment, recoupment, or forfeiture pursuant to the terms of each Policy in the event of an accounting restatement or covered conduct under the terms of the applicable Policy.

7.Taxes. The Company shall have the right to deduct from all Awards hereunder paid or any payment in respect of an Award, any federal, state, local or foreign taxes required or permitted by law to be withheld. In the case of a payment in respect of Performance Shares made in Common Stock, the Company shall reduce number of the shares of Common Stock to be distributed by an amount with a value equal to the value of such taxes required or permitted to be withheld.

8.Adjustments. In the event of any change in the outstanding shares of Common Stock of the Company or the occurrence of certain other events as described in Section 12 of the Plan, an equitable adjustment of the number of Performance Shares covered by this Award Agreement shall be made as provided in the Plan.

9.Code section 409A. It is intended that the provisions of this Award Agreement avoid the adverse consequences under section 409A of the Internal Revenue Code (the “Code”), and all provisions of the Award Agreement shall be construed and interpreted in a manner consistent with that intent. The Administrator reserves the right to make amendments to the Award Agreement as the Administrator deems necessary or desirable to avoid the imposition of taxes or penalties under section 409A of the Code. In any case, you shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on you or for your account in connection with an Award (including any taxes and penalties under section 409A of the Code), and neither the Company nor any of its affiliates shall have any obligation to indemnify or otherwise hold you harmless from any or all of such taxes or penalties.

FY2024-2026 Performance Share Payout Schedule

1.Performance Shares Earned. For the avoidance of doubt, capitalized terms that are otherwise not defined in this Attachment will have the same definition as in the Award Agreement. The number of Performance Shares earned will be determined in accordance with the following formula:

(PERFORMANCE SHARES AWARDED) x (PAYOUT FACTOR) =

(PERFORMANCE SHARES EARNED)

2.Payout Factor. The “Payout Factor” is the percentage determined under this Section 2. The Payout Factor is based on the Company’s TSR Percentile Rank among the TSR comparator group for the Performance Period. The “Initial Payout Factor” is determined in accordance with the following schedule:

Company’s TSR Percentile Rank	Initial Payout Factor
> 75th %ile	200%
> 50th %ile	100%
> 30th %ile	30%
< 30th %ile	0%

The Initial Payout Factor will be interpolated for TSR Percentile Rank between discrete points, from a minimum Initial Payout Factor of 30 percentage points to a maximum Initial Payout Factor of 200 percentage points

The Initial Payout Factor will be increased by 15 percentage points to determine the maximum Payout Factor (the “Maximum Payout Factor”), but in no event will the Maximum Payout Factor exceed 215 percentage points. The Committee, in its discretion, may decrease the Maximum Payout Factor by up to 30 percentage points (i.e., a decrease of 15 percentage points from the Initial Payout Factor) to determine the Payout Factor. The Committee, in its discretion, may adjust the amount of any individual’s payout, but the Payout Factor used for such payout may not exceed the Maximum Payout Factor.

3. Definitions.

a.Beginning Price means, with respect to the Company’s and any other TSR comparator group company’s common stock, the average of the closing sale prices of a share of such common stock on the principal exchange on which such stock is traded for the thirty (30) calendar days preceding the first day of the of the Performance Period.

b.Ending Price means, with respect to the Company’s and any other TSR comparator group company’s common stock, the average of the closing sale prices of a share of such company’s common stock on the principal exchange on which such stock is traded for thirty (30) calendar days ending with the last day of the Performance Period.

c.TSR Comparator Group for purposes of calculating the TSR Percentile Rank, shall be a fixed group of the companies that comprise the S&P 500 index at the beginning of the Performance Period (i.e., 1 October 2023), subject to the modifications described below. The TSR Comparator Group will be modified to reflect merger and acquisition activity during the Performance Period. If an S&P 500 constituent is acquired during the Performance Period, they will be removed from the index when calculating the payout. If an S&P 500 constituent has a spin, the RemainCo stays when calculating the payout, and SpinCo will be treated as a dividend. If an S&P 500 constituent goes bankrupt during the Performance Period, the company will remain in the comparator group, ranked at the bottom.

d.Total Shareholder Return or TSR shall be the percent increase/decrease in value that would be experienced from purchasing a share of the Company’s or a TSR comparator group company’s common stock at the Beginning Price and holding it for the Performance Period and selling at the Ending Price of such a share, assuming that dividends and other distributions are reinvested in additional shares of such stock at the closing market price on the ex-dividend date. Any non-cash distributions shall be valued at market value that shall be determined by the Committee.

e.TSR Rank means the ranking of the Company’s TSR among the TSRs for the TSR Comparator Group companies for the Performance Period. TSR Rank is determined by ordering the TSR comparator group companies and the Company from highest to lowest based on TSR for the Performance Period and counting down from the company with the highest TSR (ranked first) to the Company’s position on the list. If two companies are ranked equally, the ranking of the next company shall account for the tie, so that if one company is ranked first, and two companies are tied for second, the next company is ranked fourth. In the event of any ambiguity, the determination of the Committee shall be final and binding.

3.TSR Percentile Rank. The TSR Percentile Rank will be determined as follows:

The nth ranked company out of the N companies (including Air Products) would have the following TSR Percentile Rank

TSR Percentile Rank = (N — n) (N — 1)

That is, if Air Products ranked 5th out of 16 companies, its TSR Percentile Rank would be 73.3% ((16-5)/(16-1)), which would give an Initial Payout Factor of 193.3%.

Reportable Segment Disclosures

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures". The update includes enhanced disclosures about significant segment expenses and identification of the chief operating decision maker. The update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2025 as well as interim periods thereafter, although early adoption is permitted. The amendments must be applied retrospectively to all prior periods presented. We are evaluating the impact this update will have on our disclosures.

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.

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"), which is 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. We account for a VIE for which we have an equity interest and exercise significant influence but are not the primary beneficiary, such as the Jazan Integrated Gasification and Power Company joint venture ("JIGPC"), as an equity method investment. During the first quarter of fiscal year 2024, we determined that World Energy, LLC ("World Energy") is a VIE for which we have no equity interest and are not the primary beneficiary. Our variable interests in NGHC, JIGPC, and World Energy are further discussed below.

NGHC Joint Venture

The NEOM Green Hydrogen Project (the "NEOM 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. We intend to transport the green ammonia around the world to be dissociated to produce green hydrogen for transportation and industrial markets.

In May 2023, NGHC finalized the $6.7 billion engineering, procurement, and construction ("EPC") agreement with Air Products named as the main contractor and system integrator for the facility. NGHC secured non-recourse project financing of approximately $6.1 billion, which is expected to fund about 73% of the project and will be drawn over the construction period. At the same time, NGHC secured additional non-recourse credit facilities totaling approximately $500 primarily for working capital needs. Under the financing, 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. Borrowings under the financing are reflected net of unamortized discounts and debt issuance costs within "Long-term debt" on our consolidated balance sheets. Principal borrowings totaled $2,129.4 and $1,364.8 as of 31 December 2023 and 30 September 2023, respectively. The increase from 30 September 2023 primarily relates to principal borrowings of approximately $620 as of 31 December 2023 on a 2.00% fixed-rate Saudi Riyal loan facility that matures in November 2040.

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.

The table below summarizes balances associated with NGHC as reflected on our consolidated balance sheets:

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. The carrying value of our investment, including amounts attributable to noncontrolling interests, totaled $2,828.3 and $2,862.2 as of 31 December 2023 and 30 September 2023, respectively. Our loss exposure is limited to our investment in the joint venture.

Our investment 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 finalized an agreement to purchase a sustainable aviation fuel (“SAF”) facility in Paramount, California from World Energy. We determined the acquisition contains an embedded sales-type lease. As a result, we are accounting for the transaction as a financing arrangement and recorded a financing receivable of $210 as of 31 December 2023. We provided the remaining $90 million of financing available under this arrangement to World Energy in January 2024.

At the time of acquisition, we entered into a Master Project Agreement (“MPA”) containing 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. The MPA includes a tolling arrangement whereby we will receive feedstock from and produce renewable fuels for World Energy over a term that will conclude 15 years after onstream of the expansion project with the option to renew for two five-year terms.

During the first quarter of fiscal year 2024, we determined that World Energy is a VIE and our financing receivable represents a variable interest in World Energy. We are not the primary beneficiary as we do not have control over their key operating decisions, including feedstock supply, production of renewable fuels, and negotiating and executing supply agreements with customers. As of 31 December 2023, our maximum exposure to loss is approximately $1.9 billion. This includes project-related spending of $1.3 billion that is primarily capitalized within “Plant and equipment, net” and approximately $350 for open purchase commitments, both of which relate to the SAF expansion project, as well as $300 for our investment in the financing receivables discussed above.

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 gases 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, natural gas liquefaction, 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 below present our consolidated sales disaggregated by supply mode for each of our reportable segments for the first three months of fiscal years 2024 and 2023. We believe this presentation best depicts the nature, timing, type of customer, and contract terms for our sales.

Total	$1,384.2	$777.8	$791.9	$41.4	$179.4	$3,174.7	100	%

Interest income associated with financing and lease arrangements accounted for approximately 1% of our total consolidated sales during the three months ended 31 December 2023.

Remaining Performance Obligations

As of 31 December 2023, the transaction price allocated to remaining performance obligations is estimated to be approximately $27 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:

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 Euros and U.S. Dollars. The maximum remaining term of any forward exchange contract currently outstanding and designated as a cash flow hedge at 31 December 2023 is 2.9 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 Euros and U.S. Dollars.

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 December 2023		30 September 2023
	US$ Notional	Years Average Maturity	US$ Notional	Years Average Maturity
Forward Exchange Contracts:
Cash flow hedges	$4,658.6	0.6	$4,463.2	0.7
Net investment hedges	898.5	2.3	864.0	2.5
Not designated	585.1	0.3	709.4	0.3
Total Forward Exchange Contracts	$6,142.2	0.8	$6,036.6	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 €1,930.7 million ($2,131.3) at 31 December 2023 and €1,938.6 million ($2,049.7) at 30 September 2023. The designated foreign currency-denominated debt is presented within "Long-term debt" on the 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 December 2023, 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, Indian Rupee, and Chilean Peso.

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

	31 December 2023						30 September 2023

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 $69.6 and $94.2 as of 31 December 2023 and 30 September 2023, 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 $107.5 and $345.0 as of 31 December 2023 and 30 September 2023, 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:

Short-term Investments

Short-term investments primarily include time deposits with original maturities greater than three months and less than one year. We estimated the fair value of our short-term investments, which approximates carrying value as of the balance sheet date, using Level 2 inputs within the fair value hierarchy. Level 2 measurements were based on current interest rates for similar investments with comparable credit risk and time to maturity.

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 7, 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 December 2023		30 September 2023
	Carrying Value	Fair Value	Carrying Value	Fair Value
Assets

The carrying amounts reported on the consolidated balance sheets for cash and cash items, short-term investments, 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.

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.

In September 2010, the Brazilian Administrative Council for Economic Defense ("CADE") issued a decision against our Brazilian subsidiary, Air Products Brasil Ltda., and several other Brazilian industrial gas companies for alleged anticompetitive activities. CADE imposed a civil fine of R$179.2 million (approximately $37 at 31 December 2023) on Air Products Brasil Ltda. This fine was based on a recommendation by a unit of the Brazilian Ministry of Justice, following an investigation beginning in 2003, which alleged violation of competition laws with respect to the sale of industrial and medical gases. The fines are based on a percentage of our total revenue in Brazil in 2003.

We have denied the allegations made by the authorities and filed an appeal in October 2010 with the Brazilian courts. On 6 May 2014, our appeal was granted and the fine against Air Products Brasil Ltda. was dismissed. CADE has appealed that ruling and the matter remains pending. We, with advice of our outside legal counsel, have assessed the status of this matter and have concluded that, although an adverse final judgment after exhausting all appeals is possible, such a judgment is not probable. As a result, no provision has been made in the consolidated financial statements. In the event of an adverse final judgment, we estimate the maximum possible loss to be the full amount of the fine of R$179.2 million (approximately $37 at 31 December 2023) plus interest accrued thereon until final disposition of the proceedings.

Additionally, in April 2023, we received a favorable ruling from a Texas state court in litigation involving disputed energy management charges related to Winter Storm Uri, a severe winter weather storm that impacted the U.S. Gulf Coast in February 2021. The ruling is subject to appeal and had no impact on our consolidated financial statements for the three months ended 31 December 2023.

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), Resource Conservation and Recovery Act ("RCRA"), and similar state environmental laws relating to the designation of certain sites for investigation or remediation. Presently, there are 27 sites on which a final settlement or remediation has not been achieved where we, usually along with others, have been designated a potentially responsible party by environmental authorities or are otherwise engaged in investigation or remediation, including cleanup activity at certain of our current and former 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. The consolidated balance sheets at 31 December 2023 and 30 September 2023 included an accrual of $63.3 and $64.5, respectively, primarily as part of other noncurrent liabilities. The environmental liabilities will be paid over a period of up to 27 years. We estimate the exposure for environmental loss contingencies to range from $63 to a reasonably possible upper exposure of $77 as of 31 December 2023.

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 the inherent uncertainties related to environmental exposures, 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

At 31 December 2023, $36.7 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. The review was completed in conjunction with requirements to maintain financial assurance per the consent order issued by the FDEP discussed below. Based on our review, we expect ongoing activities to continue for 27 years. 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 2020. There have been no significant changes to the estimated exposure range related to the Pace facility since fiscal year 2020.

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 suitable to more quickly and effectively remediate groundwater. Based on assessment results, we completed a focused feasibility study that has identified alternative approaches that may more effectively remove contaminants. We continue to review alternative remedial approaches with the FDEP and completed additional field work during 2021 to support the design of an improved groundwater recovery network with the objective of targeting areas of higher contaminant concentration and avoiding 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 initiated in fiscal year 2023 with construction expected to begin in fiscal year 2025. In fiscal year 2025, we expect to connect groundwater recovery wells and ancillary equipment to the existing groundwater recovery system. Further, we expect additional future capital expenditures to consider the extended time horizon for remediation at the site.

Piedmont

At 31 December 2023, $4.1 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 Health and Environmental Control ("SCDHEC") to address both contaminated soil and groundwater. Numerous areas of soil contamination have been addressed, and contaminated groundwater is being recovered and treated. The SCDHEC 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 2029. Thereafter, we expect this site to go into a state of monitored natural attenuation through 2047. 

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. There have been no significant changes to the estimated exposure.

Pasadena

At 31 December 2023, $10.4 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 ("PUI") 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, as required, impacted soils, investigating groundwater west of the former PUI facility, 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. 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 Compensation

SHARE-BASED COMPENSATION

Our outstanding share-based compensation programs include deferred stock units and stock options. During the three months ended 31 December 2023, we granted market-based and time-based deferred stock units. Under all programs, the terms of the awards are fixed at the grant date. We issue shares from treasury stock upon the payout of deferred stock units and the exercise of stock options. As of 31 December 2023, there were 1.0 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
	31 December
	2023	2022
Before-tax share-based compensation cost	$13.6	$16.9
Income tax benefit	(3.3)	(4.1)
After-tax share-based compensation cost	$10.3	$12.8

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 three months of fiscal years 2024 and 2023 was not material.

Deferred Stock Units

During the three months ended 31 December 2023, we granted 102,120 market-based deferred stock units. The market-based deferred stock units are earned over the performance period beginning 1 October 2023 and ending 30 September 2026, conditioned on the level of our total shareholder return in relation to the S&P 500 Index over the three-year performance period.

The market-based deferred stock units had an estimated grant-date fair value of $302.10 per unit, which was estimated using a Monte Carlo simulation model. 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. We generally expense the grant-date fair value of these awards on a straight-line basis over the vesting period. The calculation of the fair value of market-based deferred stock units used the following assumptions:

Expected volatility	25.0	%
Risk-free interest rate	4.3	%
Expected dividend yield	2.6	%

In addition, during the three months ended 31 December 2023, we granted 132,317 time-based deferred stock units at a weighted average grant-date fair value of $273.02.

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 $95 and $80 for the three months ended 31 December 2023 and 2022, 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 December 2023 and 30 September 2023, our consolidated balance sheets included related party trade receivables of approximately $90 and $80, respectively.

Total debt owed to related parties was $294.8 and $328.3 as of 31 December 2023 and 30 September 2023, respectively, of which $136.9 and $177.6, respectively, was reflected within "Current portion of long-term debt" on our consolidated balance sheets. Our related party debt primarily includes a loan with our joint venture partner, Lu’An Clean Energy Company.

Uzbekistan Asset Purchase

On 25 May 2023, we entered into an investment agreement with the Government of the Republic of Uzbekistan and Uzbekneftegaz JSC (“UNG”) to purchase a natural gas-to-syngas processing facility in Qashqadaryo Province, Uzbekistan, for $1 billion. Under the agreement, Air Products will acquire, own, and operate the facility and supply all offtake products to UNG under a 15-year on-site contract, with UNG supplying the feedstock natural gas and utilities. We are accounting for the transaction as a financing arrangement because UNG has the right to reacquire the facility at the end of the contract term. Accordingly, progress payments of approximately $910, of which $100 was paid during the first quarter of fiscal year 2024, are reflected within "Financing receivables" on our consolidated balance sheet as of 31 December 2023.

Accrual for Business and Asset Actions

In fiscal year 2023, we recognized an expense of $27.0 for severance and other benefits associated with position eliminations and restructuring of certain organizations globally. The charge was not recorded in segment results. The table below reconciles the charge to the carrying amount of the accrual included within "Payables and accrued liabilities" on our consolidated balance sheets as of 31 December 2023:

Fiscal year 2023 charge	$27.0
Cash payments	(6.8)
Currency translation adjustment	(0.4)
Accrual as of 30 September 2023	$19.8
Cash payments	(3.4)
Currency translation adjustment	0.4
Accrual as of 31 December 2023	$16.8

Debt

Third-party long-term debt was $11,715.4 and $9,280.6 as of 31 December 2023 and 30 September 2023, respectively. The increase from 30 September 2023 was primarily due to the issuance of commercial paper as well as additional borrowings under the project financing associated with the NEOM Green Hydrogen Project as discussed in Note 3, Variable Interest Entities. As of 31 December 2023, we classified the outstanding commercial paper, which totaled approximately $1.3 billion, as well as our 3.35% Senior Note of $400 maturing in July 2024 as long-term debt as we have the ability to refinance the debt under our $2.75 billion revolving credit agreement (the “2021 Credit Agreement”) maturing in 2026. Our current intent is to refinance this debt via the U.S. public debt market.

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 estimates that unfavorably impacted operating income by approximately $30 and $25 for the three months ended 31 December 2023 and 2022, respectively.

Income Taxes

Our effective tax rate was 17.9% and 18.9% for the three months ended 31 December 2023 and 2022, respectively.

Income tax payments, net of refunds, were $90.1 and $88.5 for the three months ended 31 December 2023 and 2022, respectively.
