CABOT CORPORATION

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2024

UNAUDITED

A. Basis of Presentation

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S.”) (“GAAP”) and include the accounts of Cabot Corporation (“Cabot” or the “Company”) and its wholly-owned subsidiaries and majority-owned and controlled U.S. and non-U.S. subsidiaries. Additionally, Cabot considers consolidation of entities over which control is achieved through means other than voting rights. Intercompany transactions have been eliminated in consolidation.

The unaudited consolidated financial statements have been prepared in accordance with the requirements of Form 10-Q and consequently do not include all disclosures required by Form 10-K. Additional information may be obtained by referring to Cabot’s Annual Report on Form 10-K for its fiscal year ended September 30, 2024 (the “2024 10-K”).

The financial information submitted herewith is unaudited and reflects all adjustments which are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods ended December 31, 2024 and 2023. All such adjustments are of a normal recurring nature. The results for interim periods are not necessarily indicative of the results to be expected for the fiscal year.

B. Significant Accounting Policies

Full detail on the Company’s significant accounting policies may be obtained by referring to Note A in the 2024 10-K.

Argentinian Government Actions

The Company’s wholly-owned Argentinian subsidiary operates in a highly inflationary economy and, as a result, the functional currency of the subsidiary is Cabot’s reporting currency, the U.S. dollar. During the three months ended December 31, 2024 and 2023, the Company recorded foreign exchange losses of $2 million and $40 million, respectively, related to the revaluation of non-functional currency denominated monetary asset and liability balances. Of the $40 million of foreign exchange losses in the first quarter of fiscal 2024, $33 million related to a single devaluation action in December 2023 by the Argentine government. The Company invests cash in money market funds and recorded investment income of less than $1 million and $12 million, respectively, for the three months ended December 31, 2024 and 2023. The foreign exchange losses and investment gains are recorded in Other income (expense) in the Consolidated Statement of Operations.

Recent Accounting Pronouncements

In November 2024, the FASB issued a new standard, Expense Disaggregation Disclosures. The new guidance requires quantitative and qualitative disclosure of certain cost and expense categories in the notes to the financial statements for interim and annual reporting periods. The new standard is effective for the Company's fiscal years and interim periods beginning October 1, 2027, with early adoption permitted. The Company is currently evaluating the timing of adoption and evaluating the impact of the potential adoption of this standard on the Company’s Consolidated Financial Statements.

In March 2024, the Securities and Exchange Commission (“SEC”) issued its final rule, The Enhancement and Standardization of Climate-Related Disclosures for Investors that requires the Company to provide certain climate-related information. The rule provides a phased-in compliance period and is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. In April 2024, the SEC voluntarily stayed its rule pending completion of judicial review by the U.S. Court of Appeals for the Eighth Circuit and, therefore, the timing of the effectiveness of these disclosure requirements is uncertain. The Company is currently monitoring the timing of adoption and evaluating the impact of the potential adoption of this standard on the Company’s Consolidated Financial Statements.

In December 2023, the FASB issued a new standard, Improvements to Income Tax Disclosures. The new guidance requires additional disclosures primarily related to the income tax rate reconciliation and income taxes paid. The new standard is effective for the Company’s fiscal years and interim periods beginning October 1, 2025. The Company is currently evaluating the impact of the adoption of this standard on the Company’s Consolidated Financial Statements.

In November 2023, the FASB issued a new standard, Improvement to Reportable Segment Disclosures. The new guidance requires enhanced disclosure of significant reportable segment expenses. The new standard is effective for the Company’s current fiscal year which began October 1, 2024, and for interim periods beginning October 1, 2025. The Company is currently evaluating the impact of the adoption of this standard on the Company’s Consolidated Financial Statements.

C. Acquisitions

In October 2024, the Company completed the purchase of certain assets and licensed related technology, which the Company expects to use to manufacture certain products for its Battery Materials product line. The Company paid $27 million, which was allocated to the identifiable assets on a relative fair value basis, with $19 million allocated to property, plant and equipment and $8 million to intangible assets.

D. Goodwill and Intangible Assets

The carrying amount of goodwill attributable to each reportable segment and the changes in those balances during the three months ended December 31, 2024 are as follows:


	Reinforcement Materials			Performance Chemicals			Total
	(In millions)
Balance at September 30, 2024	$	48		$	85		$	133
Foreign currency impact		(2	)		(4	)		(6	)
Balance at December 31, 2024	$	46		$	81		$	127

The following table provides information regarding the Company’s intangible assets:


	December 31, 2024							September 30, 2024
	Gross Carrying Value		Accumulated Amortization			Net Intangible Assets		Gross Carrying Value		Accumulated Amortization			Net Intangible Assets
	(In millions)
Intangible assets with finite lives
Developed technologies(1)	$	40	$	(12	)	$	28	$	34	$	(12	)	$	22
Trademarks		2		(1	)		1		2		(1	)		1
Customer relationships		58		(30	)		28		60		(30	)		30
Total intangible assets	$	100	$	(43	)	$	57	$	96	$	(43	)	$	53

(1)

Included within Developed technologies as of December 31, 2024 is $8 million of intangible assets acquired during the first quarter of fiscal 2025 as discussed in Note C above.

Intangible assets are amortized over their estimated useful lives, which range between ten and twenty-five years, with a weighted average amortization period of approximately sixteen years. Amortization expense was $2 million and $1 million, respectively, for the three months ended December 31, 2024 and 2023. Amortization expense is included in Cost of sales, Selling and administrative expenses and Research and technical expenses in the Consolidated Statements of Operations. Total amortization expense is estimated to be approximately $6 million each year for the next five fiscal years.

E. Accumulated Other Comprehensive Income (Loss) (“AOCI”)

Comprehensive income combines net income (loss) and other comprehensive income items, which are reported as components of stockholders’ equity in the accompanying Consolidated Balance Sheets.

Changes in each component of AOCI, net of tax, were as follows:


	Currency Translation Adjustment			Pension and Other Post-retirement Benefit Liability Adjustments			Total
	(In millions)
Balance at September 30, 2024, attributable to Cabot Corporation	$	(342	)	$	(18	)	$	(360	)
Other comprehensive income (loss) before reclassifications		(104	)		—			(104	)
Amounts reclassified from AOCI		—			—			—
Less: Other comprehensive income (loss) attributable to noncontrolling interests		(7	)		—			(7	)
Balance at December 31, 2024, attributable to Cabot Corporation	$	(439	)	$	(18	)	$	(457	)


	Currency Translation Adjustment			Pension and Other Post-retirement Benefit Liability Adjustments			Total
	(In millions)
Balance at September 30, 2023, attributable to Cabot Corporation	$	(353	)	$	(9	)	$	(362	)
Other comprehensive income (loss) before reclassifications		62			—			62
Amounts reclassified from AOCI		(1	)		—			(1	)
Less: Other comprehensive income (loss) attributable to noncontrolling interests		4			—			4
Balance at December 31, 2023, attributable to Cabot Corporation	$	(296	)	$	(9	)	$	(305	)

For both three months ended December 31, 2024 and 2023, the Company reclassified $1 million of gain associated with net investment hedges and $1 million and nil, respectively, of losses excluded from net investment hedges effectiveness testing out of AOCI and into interest expense on the Consolidated Statements of Operations.

F. Contingencies

Respirator Liabilities

Cabot has exposure in connection with a safety respiratory products business that a subsidiary acquired from American Optical Corporation (“AO”) in an April 1990 asset purchase transaction. The subsidiary manufactured respirators under the AO brand and disposed of that business in July 1995. In connection with its acquisition of the business, the subsidiary agreed, in certain circumstances, to assume a portion of AO’s liabilities, including costs of legal fees together with amounts paid in settlements and judgments, allocable to AO respiratory products used prior to the 1990 purchase by the Cabot subsidiary. In exchange for the subsidiary’s assumption of certain of AO’s respirator liabilities, AO agreed to provide to the subsidiary the benefits of: (i) AO’s insurance coverage for the period prior to the 1990 acquisition and (ii) a former owner’s indemnity of AO holding it harmless from any liability allocable to AO respiratory products used prior to May 1982. As more fully described in the 2024 10-K, the respirator liabilities generally involve claims for personal injury, including asbestosis, silicosis and coal worker’s pneumoconiosis, allegedly resulting from the use of respirators that are alleged to have been negligently designed and/or labeled. At no time did this respiratory product line represent a significant portion of the respirator market. In addition to Cabot’s subsidiary, other parties are responsible for significant portions of the costs of these respirator liabilities (as defined in the 2024 10-K, the “Payor Group”).

Cabot has a reserve to cover its expected share of liabilities for pending and future respirator liability claims, which is included in Other liabilities and Accounts payable and accrued liabilities on the Consolidated Balance Sheets. The Company expects these liabilities to be incurred over a number of years. The reserve balance was $34 million and $35 million at December 31, 2024 and September 30, 2024, respectively.

The Company’s current estimate of the cost of its share of pending and future respirator liability claims is based on facts and circumstances existing at this time, including the number and nature of the remaining claims. Developments that could affect the Company’s estimate include, but are not limited to, (i) significant changes in the number of future claims, (ii) changes in the rate of dismissals without payment of pending claims, (iii) significant changes in the average cost of resolving claims, including potential settlements of groups of claims, (iv) significant changes in the legal costs of defending these claims, (v) changes in the nature of claims received or changes in our assessment of the viability of these claims, (vi) trial and appellate outcomes, (vii) changes in the law and procedure applicable to these claims, (viii) the financial viability of the parties that contribute to the payment of respirator claims, (ix) exhaustion or changes in the recoverability of the insurance coverage maintained by certain members of the Payor Group, or a change in the availability of the indemnity provided by a former owner of AO, (x) changes in the allocation of costs among the various parties paying legal and settlement costs, and (xi) a determination that the assumptions that were used to estimate Cabot’s share of liability are no longer reasonable. The Company cannot determine the impact of these potential developments on its current estimate of its share of liability for existing and future claims. Because reserves are limited to amounts that are probable and estimable as of a relevant measurement date, and there is inherent difficulty in projecting the impact of potential developments on Cabot’s share of liability for these existing and future claims, it is reasonably possible that the liabilities for existing and future claims could change in the near term and that change could be material.

Other Matters

The Company has various other lawsuits, claims and contingent liabilities arising in the ordinary course of its business and with respect to its divested businesses. The Company does not believe that any of these matters will have a material adverse effect on its financial position; however, litigation is inherently unpredictable. Cabot could incur judgments, enter into settlements or revise its expectations regarding the outcome of certain matters, and such developments could have a material impact on its results of operations in the period in which the amounts are accrued or its cash flows in the period in which the amounts are paid.

G. Income Tax

Effective Tax Rate


	Three Months Ended December 31
	2024			2023
	(Dollars in millions)
(Provision) benefit for income taxes	$	(41	)	$	(34	)
Effective tax rate		28	%		36	%

For the three months ended December 31, 2024 and 2023, the provision for income taxes included a net discrete tax expense of $2 million and $7 million, respectively.

Income tax in Interim Periods

The Company records its tax provision or benefit on an interim basis using an estimated annual effective tax rate. This rate is applied to the current period ordinary income or loss to determine the income tax provision or benefit allocated to the interim period. The income tax effects of unusual or infrequent items are excluded from the estimated annual effective tax rate and are recognized in the impacted interim period. Losses from jurisdictions for which no benefit can be recognized are excluded from the overall computations of the estimated annual effective tax rate and a separate estimated annual effective tax rate is computed and applied to ordinary income or loss in the loss jurisdiction.

Valuation allowances are provided against the future tax benefits that arise from the deferred tax assets in jurisdictions for which the Company expects that no benefit can be recognized. The estimated annual effective tax rate may be significantly impacted by nondeductible expenses and the Company’s projected earnings mix by tax jurisdiction. Adjustments to the estimated annual effective income tax rate are recognized in the period when such estimates are revised.

Uncertainties

Cabot and certain subsidiaries are under audit in a number of jurisdictions. In addition, certain statutes of limitations are scheduled to expire in the near future. It is reasonably possible that a change in the unrecognized tax benefits may also occur within the next twelve months related to the settlement of one or more of these audits or the lapse of applicable statutes of limitations. However, an estimated range of the impact on the unrecognized tax benefits cannot be quantified at this time.

Cabot files U.S. federal and state and non-U.S. income tax returns in jurisdictions with varying statutes of limitations. The 2021 through 2023 tax years generally remain subject to examination by the IRS and various tax years from 2021 through 2023 remain subject to examination by the respective state tax authorities. In foreign jurisdictions, various tax years from 2006 through 2024 remain subject to examination by their respective tax authorities.

During the three month periods ended December 31, 2024 and 2023, Cabot released uncertain tax positions of $2 million and $1 million, respectively, due to the expiration of statutes of limitations in various jurisdictions.

Participating securities consist of shares underlying unvested time-based restricted stock units (the "TSUs"), earned and unvested performance-based restricted stock units (the "PSUs", and referred to in this note collectively with the TSUs as the "RSUs"), stock units accounted for under the Supplemental 401(k) Plan portion of the Company’s Deferred Compensation and Supplemental Retirement Plan, and stock units and phantom stock units accounted for under the Company’s Non-Employee Directors’ Deferral Plan. The holders of RSUs are entitled to receive dividend equivalents, payable in cash, to the extent dividends are paid on the outstanding shares of Common Stock, and equal in value to the dividends that would have been paid in respect of the Common Stock underlying the RSU. The accounts of holders of stock units and phantom stock units are credited with dividend equivalents, which are payable, in stock or cash, as the case may be, with the distribution of account balances.

Undistributed earnings are the earnings which remain after dividends declared during the period are assumed to be distributed to the common and participating stockholders. Undistributed earnings are allocated to common and participating stockholders on the same basis as dividend distributions. The calculation of undistributed earnings is as follows:


	Three Months Ended December 31
	2024		2023
	(In millions)
Calculation of undistributed earnings (loss):
Net income (loss) attributable to Cabot Corporation	$	93	$	50
Less: Dividends declared on common stock		24		22
Less: Dividends declared on participating securities		—		—
Undistributed earnings (loss)	$	69	$	28

Allocation of undistributed earnings (loss):
Undistributed earnings (loss) allocated to common stockholders	$	68	$	27
Undistributed earnings allocated to participating stockholders		1		1
Undistributed earnings (loss)	$	69	$	28

Undistributed earnings are adjusted for the assumed distribution of dividends to the dilutive securities, which are described in (3) below, and then reallocated to participating securities.

(3)

Represents incremental shares of common stock from the assumed exercise of stock options issued under Cabot’s equity incentive plans. For the three months ended December 31, 2024 and 2023, 63,807 and 330,331 incremental shares of common stock, respectively, were excluded from the calculation of diluted earnings per share because the inclusion of these shares would have been antidilutive.

I. Financial Instruments and Fair Value Measurements

The FASB authoritative guidance on fair value measurements defines fair value, provides a framework for measuring fair value, and requires certain disclosures about fair value measurements. The required disclosures focus on the inputs used to measure fair value. The guidance establishes the following hierarchy for categorizing these inputs:


Level 1	—	Quoted market prices in active markets for identical assets or liabilities

Level 2	—	Significant other observable inputs (e.g., quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs)

Level 3	—	Significant unobservable inputs

There were no transfers of financial assets or liabilities measured at fair value between Level 1 and Level 2 and there were no Level 3 investments during the first three months of either fiscal 2025 or 2024.

At December 31, 2024 and September 30, 2024, the fair values of cash and cash equivalents, accounts and notes receivable, accounts payable and accrued liabilities, and short-term borrowings and variable rate debt approximated their carrying values due to the short-term nature of these instruments. Cash and cash equivalents are classified as Level 1 within the fair value hierarchy.

At December 31, 2024 and September 30, 2024, Cabot had derivatives relating to foreign currency risks, including a net investment hedge and forward foreign currency contracts, carried at fair value. At December 31, 2024 and September 30, 2024, the fair value of the net investment hedge was an asset of $17 million and $1 million, respectively, and was included in Prepaid expenses and other current assets and Other Assets on the Consolidated Balance sheets. At December 31, 2024 and September 30, 2024, the fair value of the forward currency contracts was a net asset of less than $1 million and an asset of less than $1 million, respectively, and was included in Prepaid expenses and other current assets and Accounts payable and accrued liabilities on the Consolidated Balance Sheets. These derivatives are classified as Level 2 instruments within the fair value hierarchy as the fair value determination was based on observable inputs.

At both December 31, 2024 and September 30, 2024, the fair value of guaranteed investment contracts included in Other assets on the Consolidated Balance Sheets was $8 million. Guaranteed investment contracts were classified as Level 2 instruments within the fair value hierarchy as the fair value determination was based on other observable inputs.

The carrying value and fair value of the long-term fixed rate debt were $1.08 billion and $1.06 billion, respectively, as of December 31, 2024, and $1.08 billion and $1.08 billion, respectively, as of September 30, 2024. The fair values of Cabot’s fixed rate long-term debt are estimated based on comparable quoted market prices at the respective period ends. The carrying amounts of Cabot’s floating rate long-term debt and finance and operating lease obligations approximate their fair values. All such measurements are based on observable inputs and are classified as Level 2 within the fair value hierarchy. The valuation technique used is the discounted cash flow model.

J. Supplier Financing Programs

The Company maintains supply chain finance agreements with third-party financial institutions. These agreements allow the Company’s participating suppliers to sell their receivables to such third-party financial institutions to receive payment earlier than the negotiated commercial terms between the supplier and the Company. Such sales are at the sole discretion of the supplier, and on terms and conditions that are negotiated between the supplier and the respective financial institution. The terms and conditions of the supplier invoice, including payment terms and amounts due, are not impacted by a supplier’s participation in the program. Pursuant to the supply chain finance agreements, the Company has agreed to pay financial institutions on the original due date of the applicable invoice. There are no guarantees associated with these programs. The Company's outstanding payment obligations to financial institutions related to supplier financing programs were $14 million and $16 million as of December 31, 2024 and September 30, 2024, respectively, and are included within Accounts payable and accrued liabilities on the Consolidated Balance Sheets.

K. Financial Information by Segment

The Company identifies a product line as an operating segment if: i) it engages in business activities from which it may earn revenues and incur expenses; ii) its operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”), who is Cabot’s President and Chief Executive Officer, to make decisions about resources to be allocated to the segment and assess its performance; and iii) it has available discrete financial information. The CODM reviews financial information at the operating segment level to allocate resources and to assess the operating results and financial performance for each operating segment. Operating segments are aggregated into a reportable segment if the operating segments are determined to have similar economic characteristics and if the operating segments are similar in the following areas: i) nature of products and services; ii) nature of production processes; iii) type or class of customer for their products and services; iv) methods used to distribute the products or provide services; and v) if applicable, the nature of the regulatory environment.

The Company has two reportable segments: Reinforcement Materials and Performance Chemicals. The Reinforcement Materials segment combines the reinforcing carbons and engineered elastomer composites product lines. The Performance Chemicals segment aggregates the specialty carbons, specialty compounds, fumed metal oxides, battery materials, inkjet colorants and aerogel product lines.

Income (loss) before income taxes (“Segment EBIT”) is presented for each reportable segment in the table below. Segment EBIT excludes Interest expense, General unallocated income (expense), Unallocated corporate costs and Certain items, meaning items management does not consider representative of on-going operating segment results. In addition, Segment EBIT includes Equity in earnings of affiliated companies, net of tax, Net income attributable to noncontrolling interests, net of tax, and discounting charges for certain Notes receivable.

Financial information by reportable segment is as follows:


	Reinforcement Materials		Performance Chemicals		Segment Total		Unallocated and Other(1)			Consolidated Total
	(In millions)
Three Months Ended December 31, 2024
Revenues from external customers(2)	$	611	$	311	$	922	$	33		$	955

Income (loss) before income taxes(3)	$	129	$	34	$	163	$	(69	)	$	94

(1)

Unallocated and Other includes certain items and eliminations necessary to reflect management’s reporting of operating segment results. These items are reflective of the segment reporting presented to the CODM.

(2)

Consolidated Total Revenues from external customers reconciles to Net sales and other operating revenues on the Consolidated Statements of Operations. Revenues from external customers that are categorized as Unallocated and Other reflects external shipping and handling fees, the impact of unearned revenue, and discounting charges for certain Notes receivable. Details are provided in the table below:

(a)

Certain items are items of expense and income that management does not consider representative of the Company’s fundamental on-going segment results and they are, therefore, excluded from Segment EBIT.

(b)

Unallocated corporate costs are costs that are not controlled by the segments and primarily benefit corporate interests.

(c)

General unallocated income (expense) consists of gains (losses) arising from foreign currency transactions, net of other foreign currency risk management activities, Interest and dividend income, the profit or loss related to the corporate adjustment for unearned revenue and unrealized holding gains (losses) for investments. This does not include items of income or expense that are separately treated as Certain items.

(d)

Equity in earnings of affiliated companies, net of tax, is included in Segment EBIT and is removed in Unallocated and other to reconcile to Income (loss) from operations before income taxes and equity in earnings from affiliated companies.

The Company’s segments operate globally. In addition to presenting Revenue from external customers by reportable segment, the following tables further disaggregate Revenues from external customers by geographic region.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Recently Issued Accounting Pronouncements

Refer to the discussion under the heading “Recent Accounting Pronouncements” in Note B of our Notes to the Consolidated Financial Statements.

Results of Operations

The Company has two reportable segments: Reinforcement Materials and Performance Chemicals. Cabot is also organized for operational purposes into three geographic regions: the Americas; Europe, Middle East and Africa (“EMEA”); and Asia Pacific. The discussion of our results of operations for the periods presented reflects these structures.

Our analysis of our financial condition and operating results should be read with our consolidated financial statements and accompanying notes.

Definition of Terms and Non-GAAP Financial Measures

When discussing our results of operations, we use several terms as described below.

The term “product mix” refers to the mix of types and grades of products sold or the mix of geographic regions where products are sold, and the positive or negative impact this has on the revenue or profitability of the business and/or segment.

Our discussion under the heading “(Provision) Benefit for Income Taxes and Reconciliation of Effective Tax Rate to Operating Tax Rate” includes a discussion and reconciliation of our “effective tax rate” and our “operating tax rate” for the periods presented, as well as management’s projection of our operating tax rate range for the full fiscal year. Our operating tax rate is a non-GAAP financial measure and should not be considered as an alternative to our effective tax rate, the most comparable GAAP financial measure. The operating tax rate is calculated based upon management's forecast of the annual operating tax rate for the fiscal year applied to adjusted pre-tax earnings. The operating tax rate excludes income tax (expense) benefit on certain items, discrete tax items, and, on a quarterly basis, the timing of losses in certain jurisdictions. The income tax (expense) benefit on certain items is determined using the applicable rates in the taxing jurisdictions in which the certain items occurred and includes both current and deferred income tax (expense) benefit based on the nature of the certain items. Discrete tax items include, but are not limited to, changes in valuation allowance, uncertain tax positions, and other tax items, such as the tax impact of legislative changes and tax accruals on historic earnings due to changes in indefinite reinvestment assertions. Our definition of the operating tax rate may not be comparable to the definition used by other companies. Management believes that this non-GAAP financial measure is useful supplemental information because it helps our investors compare our tax rate year to year on a consistent basis and to understand what our tax rate on current operations would be without the impact of these items.

Our discussion under the heading “First Quarter of Fiscal 2025 versus First Quarter of Fiscal 2024—By Business Segment” includes a discussion of Total segment EBIT, which is a non-GAAP financial measure defined as Income (loss) from operations before income taxes and equity in earnings from affiliated companies less certain items and other unallocated items. Our Chief Operating Decision Maker, who is our President and Chief Executive Officer, uses segment EBIT to evaluate the operating results of each segment and to allocate resources to the segments. We believe Total segment EBIT, which reflects the sum of EBIT from our reportable segments, provides useful supplemental information for our investors as it is an important indicator of our operational strength and performance, allows investors to see our results through the eyes of management, and provides context for our discussion of individual business segment performance. Total segment EBIT should not be considered an alternative for Income (loss) from operations before income taxes and equity in earnings of affiliated companies, which is the most directly comparable U.S. GAAP financial measure. A reconciliation of Total segment EBIT to Income (loss) from operations before income taxes and equity in earnings of affiliated companies is provided under the heading “First quarter of Fiscal 2025 versus First quarter of Fiscal 2024—By Business Segment”. Investors should consider the limitations associated with this non-GAAP measure, including the potential lack of comparability of this measure from one company to another.

In calculating Total segment EBIT, we exclude from our Income (loss) from operations before income taxes and equity in earnings of affiliated companies (i) items of expense and income that management does not consider representative of our fundamental on-going segment results, which we refer to as “certain items”, and (ii) items that, because they are not controlled by the business segments and primarily benefit corporate objectives, are not allocated to our business segments, such as interest expense and other corporate costs, which include unallocated corporate overhead expenses such as certain corporate salaries and headquarter expenses, plus costs related to special projects and initiatives, which we refer to as “other unallocated items”. Management believes excluding the items identified as certain items facilitates operating performance comparisons from period to period by eliminating differences that would not otherwise be apparent on a GAAP basis and also facilitates an evaluation of our operating performance without the impact of these costs or benefits. The items of income and expense that we have excluded from

Total segment EBIT, as applicable, but that are included in our GAAP Income (loss) from operations before income taxes and equity in earnings of affiliated companies, as applicable, are described below.

•

Argentina controlled currency devaluation loss related to the foreign exchange loss from government-controlled currency devaluations on our net monetary assets denominated in the Argentine peso and investment losses related to the utilization of government bond programs established for the settlement of certain foreign payables.

•

Global restructuring activities, which include costs or benefits associated with cost reduction initiatives or plant closures and are primarily related to (i) employee termination costs, (ii) asset impairment charges associated with restructuring actions, (iii) costs to close facilities, including environmental costs and contract termination penalties, and (iv) gains realized on the sale of land or equipment associated with restructured plants or locations.

•

Legal and environmental matters and reserves, which consist of costs or benefits for matters typically related to former businesses or that are otherwise incurred outside of the ordinary course of business.

•

Acquisition and integration-related charges, which include transaction costs, redundant costs incurred during the period of integration, and costs associated with transitioning certain management and business processes to Cabot’s processes.

•

Asset impairment charges, which primarily include charges associated with an impairment of goodwill, other long-lived assets or assets held for sale.

•

Gains (losses) on sale of a business.

•

Employee benefit plan settlements, which consist of either charges or benefits associated with the termination of a pension plan or the transfer of a pension plan to a multi-employer plan.

Overview

During the first quarter of fiscal 2025, Income (loss) before income taxes and equity in earnings of affiliated companies increased compared to the first quarter of fiscal 2024. The increase was driven by lower foreign currency exchange losses primarily in Argentina and higher earnings in both our Reinforcement Materials and Performance Chemicals segments.

First quarter of Fiscal 2025 versus First quarter of Fiscal 2024—Consolidated

Net Sales and Other Operating Revenues and Gross Profit


	Three Months Ended December 31
	2024		2023
	(In millions)
Net sales and other operating revenues	$	955	$	958
Gross profit	$	235	$	218

The $3 million decrease in Net sales and other operating revenues in the first quarter of fiscal 2025 compared to the first quarter of fiscal 2024 was driven by less favorable pricing and product mix in both our Reinforcement Materials and Performance Chemicals segments ($40 million combined), partially offset by higher volumes in both our Reinforcement Materials and Performance Chemical segments ($39 million combined). The less favorable pricing and product mix in both our Reinforcement Materials and Performance Chemical segments was primarily due to lower raw material costs that are generally passed through to our customers. The higher volumes was due to higher volumes in Asia Pacific and EMEA in Reinforcement Materials and higher volumes in Performance Chemicals as volumes reconnected to underlying demand drivers in key end markets.

For the three months ended December 31, 2024, gross profit increased by $17 million compared to the same period of fiscal 2024. The increase in Gross profit in the first quarter of fiscal 2025 compared to the first quarter of fiscal 2024 was driven primarily by higher volumes in both our Reinforcement Materials and Performance Chemicals segments ($22 million combined). The higher volumes in the Reinforcement Materials segment was primarily in Asia Pacific and EMEA and the higher volumes in the Performance Chemicals segment was primarily due to volumes reconnecting to underlying demand drivers in key end markets.

Selling and Administrative Expenses

Selling and administrative expenses	$	66	$	67

Selling and administrative expenses decreased by $1 million in the first quarter of fiscal 2025 compared to the same period of fiscal 2024.

Research and Technical Expenses


	Three Months Ended December 31
	2024		2023
	(In millions)
Research and technical expenses	$	14	$	15

Research and technical expenses decreased by $1 million in the first quarter of fiscal 2025, compared to the same period of fiscal 2024.

Interest and Dividend Income, Interest Expense and Other Income (Expense)


	Three Months Ended December 31
	2024			2023
	(In millions)
Interest and dividend income	$	6		$	9
Interest expense	$	(18	)	$	(22	)
Other income (expense)	$	1		$	(29	)

Interest and dividend income decreased by $3 million in the first quarter of fiscal 2025 compared to the same period of fiscal 2024, primarily due to lower interest rates and lower average cash balances.

Interest expense decreased by $4 million in the first quarter of fiscal 2025 compared to the same period of fiscal 2024, due to lower average short-term borrowings and lower interest rates.

Other income increased by $30 million in the first quarter of fiscal 2025 compared to the same period of fiscal 2024, primarily due to lower foreign exchange losses primarily in Argentina.

(Provision) Benefit for Income Taxes and Reconciliation of Effective Tax Rate to Operating Tax Rate


	Three Months Ended December 31
	2024						2023
	(Provision) / Benefit for Income Taxes			Rate			(Provision) / Benefit for Income Taxes			Rate
Dollars in millions
Effective tax rate	$	(41	)		28	%	$	(34	)		36	%
Less: Non-GAAP tax adjustments(1)		1						4
Operating tax rate	$	(42	)		28	%	$	(38	)		28	%

(1)

Non-GAAP tax adjustments made to arrive at the operating tax provision include the income tax (expense) benefit on certain items, discrete tax items, and, on a quarterly basis, the timing of losses in certain jurisdictions, as further described above under the heading “Definition of Terms and Non-GAAP Financial Measures”.

For the three months ended December 31, 2024, the (Provision) benefit for income taxes was a provision of $41 million compared to a $34 million provision for the same period in fiscal 2024, with the change primarily due to higher earnings in the current period. Our income taxes are affected by the mix of earnings in the tax jurisdictions in which we operate, and by the presence of valuation allowances in certain tax jurisdictions.

For fiscal 2025, we expect the Operating tax rate to be in the range of 27% to 29%. We are not providing a forward-looking reconciliation of the operating tax rate range with an effective tax rate range because, without unreasonable effort, we are unable to predict with reasonable certainty the matters we would allocate to “certain items,” including unusual gains and losses, costs associated with future restructurings, acquisition-related expenses and litigation outcomes. These items are uncertain, depend on various factors, and could have a material impact on the effective tax rate in future periods.

Net Income (Loss) Attributable to Noncontrolling Interests


	Three Months Ended December 31
	2024		2023
	(In millions)
Equity in earnings of affiliated companies, net of tax	$	1	$	1
Net income (loss) attributable to noncontrolling interests, net of tax	$	11	$	11

Equity in earnings of affiliated companies, net of tax, remained flat in the first quarter of fiscal 2025, compared to the same period of fiscal 2024.

Net income (loss) attributable to noncontrolling interests, net of tax, remained flat in the first quarter of fiscal 2025, compared to the same period of fiscal 2024.

Net Income Attributable to Cabot Corporation

In the first quarter of fiscal 2025 and fiscal 2024, we reported Net income (loss) attributable to Cabot Corporation of $93 million ($1.67 per diluted common share) and $50 million ($0.88 per dilution common share), respectively. The higher net income in the first quarter of fiscal 2025 compared with the same period in fiscal 2024 is primarily due to lower Argentina controlled currency devaluation and other losses ($33 million) and higher Total segment EBIT ($12 million).

First quarter of Fiscal 2025 versus First quarter of Fiscal 2024—By Business Segment

Income (loss) before income taxes and equity in earnings of affiliated companies, Certain items, Other unallocated items and Total segment EBIT for the three months ended December 31, 2024 and 2023 are included in the following table, and details of each item is set forth in the sections below.


	Three Months Ended December 31
	2024			2023

	2024			2023
	(In millions)
Interest expense	$	(18	)	$	(22	)
Unallocated corporate costs		(13	)		(17	)
General unallocated income (expense)		7			13
Less: Equity in earnings of affiliated companies, net of tax		1			1
Total other unallocated items	$	(25	)	$	(27	)

Total other unallocated items decreased by $2 million for the three months ended December 31, 2024, when compared to the same periods in fiscal 2024, primarily due to lower Interest expense and lower Unallocated Corporate costs, partially offset by lower General unallocated income.

A discussion of items that we refer to as “other unallocated items” can be found under the heading “Definition of Terms and Non-GAAP Financial Measures”. The balances of unallocated corporate costs are primarily comprised of expenditures related to managing a public company that are not allocated to the segments and corporate business development costs related to ongoing corporate projects. The balances of General unallocated income (expense) consist of gains (losses) arising from foreign currency transactions, net of other foreign currency risk management activities, interest and dividend income, the profit or loss related to the corporate adjustment for unearned revenue and unrealized holding gains (losses) for investments. This does not include items of income or expense from the items that are separately treated as Certain items.

Reinforcement Materials

Sales and EBIT for Reinforcement Materials for the first quarter of fiscal 2025 and 2024 were as follows:


	Three Months Ended December 31
	2024		2023
	(In millions)
Reinforcement Materials Sales	$	611	$	641
Reinforcement Materials EBIT	$	130	$	129

Sales in Reinforcement Materials decreased by $30 million in the first quarter of fiscal 2025 compared to the same period of fiscal 2024, primarily due to less favorable pricing and product mix ($28 million) and lower energy center revenue ($5 million), partially offset by higher volumes primarily in Asia Pacific and EMEA ($5 million). The less favorable pricing and product mix was primarily due to lower raw material costs that are generally passed through to our customers, partially offset by higher pricing in our calendar year 2024 customer agreements.

EBIT in Reinforcement Materials in the first quarter of fiscal 2025 increased by $1 million compared to the same period of fiscal 2024. The increase in EBIT was driven by volume growth of approximately 1% primarily in Asia Pacific and EMEA ($2 million), partially offset by lower gross profit per ton ($1 million). The lower gross profit per ton was primarily due to lower energy center revenue and a less favorable geographic mix, partially offset with favorable pricing and product mix in our 2024 calendar year customer agreements.

As we look to the second quarter of the fiscal year, we expect the Reinforcement Materials segment EBIT to modestly improve sequentially from the first quarter of fiscal 2025 due to an anticipated favorable geographic mix. We anticipate relatively flat volumes sequentially with seasonal improvement and calendar year 2025 customer agreement gains in EMEA, partially offset with lower volumes in Asia Pacific due to the Lunar New Year holiday.

Performance Chemicals

Sales and EBIT for Performance Chemicals for the first quarter of fiscal 2025 and 2024 were as follows:


	Three Months Ended December 31
	2024		2023
	(In millions)
Performance Chemicals Sales	$	311	$	285
Performance Chemicals EBIT	$	45	$	34

Sales in Performance Chemicals increased by $26 million in the first quarter of fiscal 2025 compared to the same period of fiscal 2024, primarily due to higher volumes ($34 million) and the favorable impact from foreign currency translation ($3 million), partially offset by less favorable pricing and product mix ($12 million). The higher volumes were primarily due to volumes reconnecting to underlying demand drivers in key end markets. The less favorable pricing and product mix was primarily due to lower raw material costs which, in certain instances, are passed through to our customers through formulas and other market-based adjustments.

EBIT in Performance Chemicals increased by $11 million in the first quarter of fiscal 2025 compared to the same period of fiscal 2024 primarily due to 8% higher volumes ($20 million), partially offset by lower gross profit per ton ($8 million). The higher volumes in the first quarter of fiscal 2025 was primarily due to volumes reconnecting to underlying demand drivers in key end markets. The lower gross profit per ton was primarily due to higher costs associated with maintenance spend and new assets.

As we look to the second quarter of the fiscal year, we expect the Performance Chemicals segment EBIT to modestly improve sequentially from the first quarter of fiscal 2025 due to anticipated higher volumes, primarily from higher seasonal demand in North America and Europe.

Tariffs

Our current outlook does not include any adverse impacts from tariffs announced in February 2025 between the United States and Mexico, Canada and China. Given the dynamic nature of the tariff announcements, related delays and ongoing negotiations between countries, we are assessing the potential impact. In China and Mexico, we expect minimal direct impact as our production is sold mainly within the country. In Canada, a large portion of the production at our Canadian plants is sold in Canada, but also there is production sold to customers in the US. For reinforcing carbons and specialty carbons products, sales from our Canadian operations to almost all of these customers are pursuant to agreements that allow Cabot to pass through taxes and similar charges, such as tariffs. We are also working with our customers on potential alternative supply sources within our large plant network to minimize any negative impact from tariffs, where it is feasible. However, in all cases, if these (or other) tariffs are implemented, there could be a downstream impact on our customer's businesses, and this could impact underlying demand levels for our products.

Liquidity and Capital Resources

Overview

Our liquidity position, as measured by cash and cash equivalents plus borrowing availability, decreased by $118 million during the first three months of fiscal 2025, which was largely due to a higher outstanding commercial paper balance at the end of the period. As of December 31, 2024, we had cash and cash equivalents of $183 million and borrowing availability under our revolving credit agreements of $1.1 billion. We have access to borrowings under the following two credit agreements:

•

$1 billion unsecured revolving credit agreement (the “U.S. Credit Agreement”) with JPMorgan Chase Bank, N.A., as Administrative Agent, Citibank, N.A., as Syndication Agent, and the other lenders party thereto, which matures in August 2027. The U.S. Credit Agreement supports our issuance of commercial paper, and borrowings under it may be used for working capital, letters of credit and other general corporate purposes.

•

€300 million unsecured revolving credit agreement (the “Euro Credit Agreement”, and together with the U.S. Credit Agreement, the “Credit Agreements”), with PNC Bank, National Association, as Administrative Agent, and the other lenders party thereto, which matures in August 2027. Borrowings under the Euro Credit Agreement may be used for the repatriation of earnings of our foreign subsidiaries to the United States, the repayment of indebtedness of our foreign subsidiaries owing to us or any of our subsidiaries and for working capital and general corporate purposes.

As of December 31, 2024, we were in compliance with the debt covenants under the Credit Agreements, which, with limited exceptions, require us to comply on a quarterly basis with a leverage test requiring the ratio of consolidated net debt to consolidated EBITDA not to exceed 3.50 to 1.00. Consolidated net debt is defined as consolidated debt offset by the lesser of (i) unrestricted cash and cash equivalents and (ii) $150 million.

A significant portion of our business occurs outside the U.S. and our cash generation does not always align geographically with our cash needs. The vast majority of our cash and cash equivalent holdings tend to be held outside the U.S. We generally use a combination of U.S. earnings, repatriation of certain foreign earnings, commercial paper issuances and borrowings under our U.S. Credit Agreement to meet our U.S. cash needs. With the exception of Argentina, which has currency controls that prevent the distribution of cash, we are generally able to move cash throughout the Company through our cash pooling structures, intercompany accounts and/or distributions, as needed. Although we repatriate certain foreign earnings, cash held by foreign subsidiaries is generally considered permanently reinvested and is used to finance the subsidiaries’ operational activities and future investments. We usually reduce our commercial paper balance and, if applicable, borrowings under our Credit Agreements, at quarter-end using cash derived from customer collections, including the utilization of customer supply chain financing programs, settlement of intercompany balances and short-term intercompany loans. If additional funds are needed in the U.S., we expect to be able to repatriate cash, including cash from China, while paying any withholding or other taxes. Changes in regulations and tax laws in the U.S. or foreign countries could restrict our ability to transfer funds or impose material costs on such transfers.

As of each of December 31, 2024 and September 30, 2024, we had $113 million of borrowings under the Euro Credit Agreement and no outstanding borrowings under the U.S. Credit Agreement. There was $100 million and $45 million of commercial paper outstanding as of December 31, 2024 and September 30, 2024, respectively.

We anticipate sufficient liquidity from (i) cash on hand; (ii) cash flows from operating activities; and (iii) cash available from the Credit Agreements and our commercial paper program to meet our operational and capital investment needs and financial obligations for both the next twelve months and the foreseeable future. The liquidity we derive from cash flows from operations is, to a large degree, predicated on our ability to collect our receivables in a timely manner, the cost of our raw materials, and our ability to manage inventory levels.

The following discussion of the changes in our cash balance refers to the various sections of our Consolidated Statements of Cash Flows.

Cash Flows from Operating Activities

Cash provided by operating activities, which consists of net income adjusted for the various non-cash items included in income, changes in working capital and changes in certain other balance sheet accounts, totaled $124 million in the first three months of fiscal 2025 compared to $105 million of cash provided by operating activities during the same period of fiscal 2024.

Cash provided by operating activities in the first three months of fiscal 2025 was driven by business earnings excluding the non-cash impacts of depreciation and amortization of $37 million and cash dividends received from one of our equity investments of $12 million, which was partially offset by an increase in net working capital of $38 million. The increase in net working capital was largely driven by a decrease in Accounts Payable and accrued liabilities, and an increase in inventories, partially offset by a decrease in Accounts and notes receivable.

Cash provided by operating activities in the first three months of fiscal 2024 was driven by business earnings excluding the non-cash impacts of depreciation and amortization of $41 million and foreign exchange losses of $34 million, primarily related to devaluation of the Argentine peso, which was partially offset by an increase in net working capital of $46 million. The increase in net working capital was largely driven by a decrease in Accounts payable and accrued expenses and an increase in Inventories and Accounts and notes receivable.

Cash Flows from Investing Activities

Investing activities consumed $104 million of cash in the first three months of fiscal 2025 compared to $54 million of cash consumed in the first three months of fiscal 2024.

In the first three months of fiscal 2025 and 2024, investing activities included $77 million and $54 million, respectively, of capital expenditures for sustaining and compliance capital projects at our operating facilities as well as growth-related capital. In addition, in the first three months of fiscal 2025, investing activities included $27 million for cash paid for the asset acquisition described in Note C of our Notes to the Consolidated Financial Statements.

Capital expenditures for fiscal 2025 are expected to be between $250 million and $300 million. Our planned capital spending program for fiscal 2025 is for sustaining, compliance and improvement capital projects at our operating facilities as well as capacity expansion capital expenditures.

Province of Ontario Regulation 419 Update

As described in Part 1, Item 1 of the 2024 10-K under the heading “Safety, Health, Environment, and Sustainability”, under the Province of Ontario Ministry of Environment, Conservation and Parks’ (“MECP”) Regulation 419, a new requirement for sulfur dioxide (“SO2”) emissions went into effect on July 1, 2023 for our reinforcing carbons plant in Sarnia, Ontario. We are out of compliance with this new air standard. MECP has approved our proposed abatement plan, which requires us to install air pollution controls at the plant by July 1, 2028. As part of our abatement plan, we will continue to engage with MECP and other stakeholders. To date, our operations in Sarnia have not been restricted because of this matter. We anticipate that we will need to incur significant capital costs for the installation of these new SO2 emissions controls, particularly during the 24-month period prior to the date of installation.

Cash Flows from Financing Activities

Financing activities consumed $24 million of cash in the first three months of fiscal 2025 compared to $29 million of cash consumed during the same period of fiscal 2024.

In the first three months of fiscal 2025, financing activities primarily consisted of share repurchases of $42 million, dividend payments to stockholders of $24 million, and cash dividends paid to noncontrolling interests of $20 million. These payments were partially offset by net proceeds from the issuance of commercial paper of $55 million and proceeds from long-term debt of $6 million under our Euro Credit Agreement.

In the first three months of fiscal 2024, financing activities primarily consisted of share repurchases of $33 million, dividend payments to stockholders of $22 million, and cash dividends paid to noncontrolling interests of $12 million. These payments were partially offset by net proceeds from commercial paper of $32 million and proceeds from sales of common stock of $7 million from stock option exercises.

Forward-Looking Information

This report on Form 10-Q contains “forward-looking statements” under the Federal securities laws. These forward-looking statements address expectations or projections about the future, including our expectations regarding our future business performance and overall prospects, including for earnings, geographic mix and volumes in our Reinforcement Materials segment in the second quarter of fiscal 2025, and for earnings and volumes in our Performance Chemicals segment in the second quarter of fiscal 2025, and the principal assumptions underlying these expectations; the possible impact of recently announced trade tariffs between the United States and Mexico, Canada, and China on our operations, results of operations, and demand for our products, the sufficiency of our cash on hand, cash provided from operations and cash available under our credit and commercial paper facilities to fund our cash requirements in both the next twelve months and the foreseeable future; anticipated capital spending; regulatory developments, including regulatory compliance costs and potential impact on our operations; cash requirements and uses of available cash, including future cash outlays associated with respirator liabilities and the timing of such outlays; amortization expenses; our operating tax rate; and the possible outcome of legal and environmental proceedings. From time to time, we also provide forward-looking statements in other materials we release to the public and in oral statements made by authorized officers.

Forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, potentially inaccurate assumptions, and other factors, some of which are beyond our control or difficult to predict. If known or unknown risks materialize, our actual results could differ materially from those expressed in the forward-looking statements.

In addition to factors described elsewhere in this report, the following are some of the factors that could cause our actual results to differ materially from those expressed in our forward-looking statements: industry capacity utilization and competition from other specialty chemical companies; safety, health and environmental requirements and related constraints imposed on our business; regulatory and financial risks related to climate change developments; volatility in the price and availability of energy and raw materials, including with respect to the Russian invasion of Ukraine and the U.S.-China trade relationship; a significant adverse change in a customer or joint venture relationship or the failure of a customer or joint venture partner to perform its obligations under agreements with us; failure to achieve growth expectations from new products, applications and technology developments; failure to realize benefits from acquisitions, alliances, or joint ventures or achieve our portfolio management objectives; negative or uncertain worldwide or regional economic conditions and market opportunities, including from trade relations, global health matters or geo-political conflicts; litigation or legal proceedings; interest rates, tax rates, currency exchange controls, and fluctuations in foreign currency, such as the recent currency movements in Argentina; our inability to complete capacity expansions or other development projects; and the accuracy of the assumptions we used in establishing reserves for our share of liability for respirator claims. These other factors and risks are discussed more fully in our 2024 10-K and in our subsequent SEC filings.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Information about market risks for the period ended December 31, 2024 does not differ materially from that discussed under Item 7A of our 2024 10-K.

Item 4. Controls and Procedures

As of December 31, 2024, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended. Based upon that evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of that date.

There were no changes in our internal controls over financial reporting that occurred during our fiscal quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
