Jun. 30, 2026

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

Fair value is defined as 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 consists of three levels to prioritize the inputs used in valuations, as defined below:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3: Inputs that are unobservable.

As of June 30, 2026, the fair values of the Company’s financial assets and financial liabilities measured at fair value on a recurring basis are categorized as follows:


(in thousands)	Level 1		Level 2		Level 3		Total
Assets:
Derivatives (1)	$	—	$	32	$	—	$	32
Total assets at fair value	$	—	$	32	$	—	$	32

Liabilities:
Derivatives (1)	$	—	$	213	$	—	$	213
Total liabilities at fair value	$	—	$	213	$	—	$	213

As of June 30, 2025, the fair value of the Company’s financial assets and financial liabilities measured at fair value on a recurring basis are categorized as follows:


(in thousands)	Level 1		Level 2		Level 3		Total
Assets:
Derivatives (1)	$	—	$	88	$	—	$	88
Total assets at fair value	$	—	$	88	$	—	$	88

Liabilities:
Derivatives (1)	$	—	$	81	$	—	$	81

Total liabilities at fair value	$	—	$	81	$	—	$	81

(1) Currency derivatives are valued based on observable market spot and forward rates and are classified within Level 2 of the fair value hierarchy.

There have been no changes in classification and transfers between levels in the fair value hierarchy in the current period.

- Definition

Segment Reporting [Abstract]

SEGMENT DATA

The Company manages and reports its business in the following two segments: Metal Cutting and Infrastructure. The Company's reportable operating segments have been determined in accordance with the Company's internal management structure, which is organized based on operating activities, the manner in which we organize segments for making operating decisions and assessing performance and the availability of separate financial results. The Company's chief operating decision maker is its President and Chief Executive Officer. The President and Chief Executive Officer regularly reviews the discrete financial information of the Metal Cutting and Infrastructure reportable operating segments to assess performance and make decisions about the allocation of resources. The primary measure of profit or loss considered by the President and Chief Executive Officer when evaluating reportable operating segment performance is segment operating income. We do not allocate certain corporate expenses related to executive retirement plans, the Company’s Board of Directors and strategic initiatives, as well as certain other costs and report them in Corporate. Our reportable operating segments do not represent the aggregation of two or more operating segments.

Sales to a single customer did not aggregate to more than five percent of total sales in 2026, 2025 and 2024.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We assess, identify and manage cybersecurity risks through a structured process. We rely on the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework to guide our approach; covering risk identification, analysis, prioritization and treatment. We continuously monitor and mitigate identified risks, particularly those deemed significant to the Company, including, but not limited to: operational risk (i.e., disruption of business operations); intellectual property theft; fraud; extortion; harm to employees or customers; violation of privacy laws and other litigation and legal risk; and reputational risk, which are tracked through our enterprise risk management program. We closely oversee risks associated with using third-party service providers. This involves evaluating their adherence to our security requirements, conducting technical assessments, monitoring their operational performance and establishing incident reporting protocols when our information is impacted by cyber incidents. Despite our efforts, we acknowledge the potential impact of cyber threats on our operations and business. While the Company has not experienced any significant risks from cyber threats to date, we recognize the potential consequences, including operational disruptions, legal costs, damage to our reputation and financial impacts. We remain vigilant and proactive in managing these risks. We deploy state-of-the-art technologies and services to help us identify and respond to security incidents, manage a 24/7 Security Operations Center and regularly test our preparedness for cyber incidents. These efforts enable us to effectively recognize and respond to low-impact incidents, avoiding their escalation to more problematic situations.

Summary of Significant Accounting Policies (Policies)

Jun. 30, 2026

Accounting Policies [Abstract]

PRINCIPLES OF CONSOLIDATION

PRINCIPLES OF CONSOLIDATION The consolidated financial statements include our accounts and those of our subsidiaries in which we have a controlling interest. All intercompany balances and transactions are eliminated.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS In preparing our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), we make judgments and estimates about the amounts reflected in our consolidated financial statements. As part of our financial reporting process, our management collaborates to determine the necessary information on which to base our judgments and develop estimates used to prepare the consolidated financial statements. We use historical experience and available information to make these judgments and estimates. Actual amounts could differ from the estimates reflected in our consolidated financial statements.

CASH AND CASH EQUIVALENTS

CASH AND CASH EQUIVALENTS Cash investments having original maturities of three months or less are considered cash equivalents. Cash equivalents principally consist of investments in money market funds and bank deposits at June 30, 2026.

ACCOUNTS RECEIVABLE

ACCOUNTS RECEIVABLE We market our products to a diverse customer base throughout the world. Trade credit is extended based upon periodically updated evaluations of each customer’s ability to satisfy its obligations. We record allowances for estimated losses resulting from the inability of our customers to make required payments. We assess the creditworthiness of our customers based on multiple sources of information and analyze additional factors such as our historical bad debt experience, industry concentrations of credit risk, current economic trends, changes in customer payment terms and forward-looking information.

INVENTORIES

INVENTORIES We use the last-in, first-out (LIFO) method for determining the cost of a significant portion of our United States (U.S.) inventories, and they are stated at the lower of cost or market. The cost of the remainder of our inventories is measured using approximate costs determined on the first-in, first-out basis or using the average cost method, and are stated at the lower of cost or net realizable value. When market conditions indicate an excess of carrying costs over market value, a lower of cost or net realizable value provision or a lower of cost or market provision, as applicable, is recorded. Once inventory is determined to be excess or obsolete, a new cost basis is established that is not subsequently written back up in future periods.

PROPERTY, PLANT AND EQUIPMENT

PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are carried at cost. Major improvements are capitalized, while maintenance and repairs are expensed as incurred. Retirements and disposals are removed from cost and accumulated depreciation accounts, with the gain or loss reflected in operating income. Interest related to the construction of major facilities is capitalized as part of the construction costs and is depreciated over the facilities' estimated useful lives.

Depreciation for financial reporting purposes is generally computed using the straight-line method over the following estimated useful lives: building and improvements over 15-40 years; machinery and equipment over 4-15 years; furniture and fixtures over 5-10 years and computer hardware and software over 3-7 years.

LONG-LIVED ASSETS

LONG-LIVED ASSETS We evaluate the recoverability of property, plant and equipment, operating lease right-of-use (ROU) assets and intangible assets that are amortized, whenever events or changes in circumstances indicate the carrying amount of any such assets may not be fully recoverable. Changes in circumstances include technological advances, changes in our business model, capital structure, economic conditions or operating performance. Our evaluation is performed at the asset group level, based upon, among other things, our assumptions about the estimated future undiscounted cash flows these assets are expected to generate. When the sum of the undiscounted cash flows is less than the carrying value, we will recognize an impairment loss to the extent that carrying value exceeds fair value. We apply our best judgment when performing these evaluations to determine if a triggering event has occurred, the undiscounted cash flows used to assess recoverability and the fair value of the asset group.

GOODWILL AND OTHER INTANGIBLE ASSETS

GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of cost over the fair value of the net assets of acquired companies. Goodwill is tested at least annually for impairment. We perform our annual impairment test during the June quarter in connection with our annual planning process unless there are impairment indicators that warrant a test prior to that quarter. As of June 30, 2026, only the Metal Cutting reporting unit has goodwill recorded. We completed annual tests of goodwill impairment and recorded no impairments during 2026, 2025 or 2024 for our Metal Cutting reporting unit. We can use a qualitative test, known as "Step 0," or a quantitative method to determine whether impairment has occurred. In 2026 and 2024, we elected to perform Step 0 and were not required to conduct the quantitative analysis. In 2025, we performed a quantitative "Step 1" analysis using a combination of a discounted cash flow analysis and market multiples based upon historical and projected financial information. We apply our best judgment when assessing the reasonableness of the assumptions used to determine the fair value of the reporting unit.

The majority of our intangible assets with definite lives are amortized on a straight-line basis, while certain customer-related intangible assets are amortized on an accelerated method. Identifiable assets with finite lives are reviewed for impairment when events or circumstances indicate that the carrying value may not be recoverable.

PENSION AND OTHER POSTRETIREMENT BENEFITS

PENSION AND OTHER POSTRETIREMENT BENEFITS We sponsor these types of benefit plans for certain employees and retirees. Accounting for the cost of these plans requires the estimation of the cost of the benefits to be provided well into the future and attributing that cost over either the expected work life of employees or over the average life of participants participating in these plans, depending on plan status and on participant population. This estimation requires our judgment about the discount rate used to determine these obligations, expected return on plan assets, rate of future compensation increases, withdrawal and mortality rates and participant retirement age. Differences between our estimates and actual results may significantly affect the cost of our obligations under these plans.

In the valuation of our pension and other postretirement benefit liabilities, management utilizes various assumptions. Discount rates are derived by identifying a theoretical settlement portfolio of high quality corporate bonds sufficient to provide for a plan’s projected benefit payments. This rate can fluctuate based on changes in the corporate bond yields.

The long-term rate of return on plan assets is estimated based on an evaluation of historical returns for each asset category held by the plans, coupled with the current and short-term mix of the investment portfolio. The historical returns are adjusted for expected future market and economic changes. This return will fluctuate based on actual market returns and other economic factors.

Future compensation rates, withdrawal rates and participant retirement age are determined based on historical information. These assumptions are not expected to significantly change. Mortality rates are determined based on a review of published mortality tables.

EARNINGS PER SHARE

EARNINGS PER SHARE Basic earnings per share is computed using the weighted average number of shares outstanding during the period, while diluted earnings per share is calculated to reflect the potential dilution that would occur related to the issuance of capital stock under stock option grants, performance awards and restricted stock units. The difference between basic and diluted earnings per share relates solely to the effect of capital stock options, performance awards and restricted stock units.

The following tables provide the computation of diluted shares outstanding:


(in thousands)	2026	2025	2024
Weighted-average shares outstanding during period	76,215	77,264	79,390
Add: Unexercised stock options and unvested restricted stock units	1,209	630	575
Number of shares on which diluted earnings per share is calculated	77,424	77,894	79,965
Unexercised stock options with an exercise price greater than the average market price and restricted stock units not included in the computation because they were anti-dilutive	10	274	396

REVENUE RECOGNITION AND SHIPPING AND HANDLING FEES AND COSTS

REVENUE RECOGNITION The Company's contracts with customers are comprised of purchase orders, and for larger customers, may also include long-term agreements. We account for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. These contracts with customers typically relate to the manufacturing of products, which represent single performance obligations that are satisfied when control of the product passes to the customer. The Company considers the timing of right to payment, transfer of risk and rewards, transfer of title, transfer of physical possession and customer acceptance when determining when control transfers to the customer. As a result, revenue is generally recognized at a point in time - either upon shipment or delivery - based on the specific shipping terms in the contract. The shipping terms vary across all businesses and depend on the product, customary local commercial terms and the type of transportation. Shipping and handling activities are accounted for as activities to fulfill a promise to transfer a product to a customer and as such, costs incurred are recorded when the related revenue is recognized. Payment for products is due within a limited time period after shipment or delivery, typically within 30 to 90 calendar days of the respective invoice dates. The Company does not generally offer extended payment terms.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Amounts billed and due from our customers are classified as accounts receivable, less allowance for doubtful accounts on the consolidated balance sheets. Certain contracts with customers, primarily distributor customers, have an element of variable consideration that is estimated when revenue is recognized under the contract. Variable consideration primarily includes volume incentive rebates, which are based on achieving a certain level of purchases and other performance criteria as established by our distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned. The majority of our products are consumed by our customers or end users in the manufacture of their products. Historically, we have experienced very low levels of returned products and do not consider the effect of returned products to be material. We have recorded an estimated returned goods allowance to provide for any potential returns.

We warrant that products sold are free from defects in material and workmanship under normal use and service when correctly installed, used and maintained. This warranty terminates 30 days after delivery of the product to the customer and does not apply to products that have been subjected to misuse, abuse, neglect or improper storage, handling or maintenance. Products may be returned to Kennametal only after inspection and approval by Kennametal and upon receipt by the customer of shipping instructions from Kennametal. We have included an estimated allowance for warranty returns in our returned goods allowance discussed above.

The Company records a contract asset when it has a right to payment from a customer that is conditioned on events that have occurred other than the passage of time. The Company also records a contract liability when customers prepay but the Company has not yet satisfied its performance obligation. The Company did not have any material remaining performance obligations, contract assets or liabilities as of June 30, 2026 and 2025.

The Company pays sales commissions related to certain contracts, which qualify as incremental costs of obtaining a contract. However, the Company applies the practical expedient that allows an entity to recognize incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less. These costs are recorded within operating expense in our consolidated statements of income.

SHIPPING AND HANDLING FEES AND COSTS All fees billed to customers for shipping and handling are classified as a component of sales. All costs associated with shipping and handling are classified as a component of cost of goods sold.

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION We recognize stock-based compensation expense for all stock options, restricted stock awards and restricted stock units over the period from the date of grant to the date when the award is no longer contingent on the employee providing additional service (substantive vesting period). Forfeitures are recorded as incurred. We utilize the Black-Scholes valuation method to establish the fair value of all stock option awards. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model.

RESEARCH AND DEVELOPMENT COSTS

RESEARCH AND DEVELOPMENT COSTS Research and development costs of $43.2 million, $44.4 million and $44.2 million in 2026, 2025 and 2024, respectively, were expensed as incurred. These costs are included in operating expense in the consolidated statements of income.

INCOME TAXES

INCOME TAXES The Company’s provision for income taxes is calculated based on income and statutory tax rates in the various jurisdictions in which the Company operates and requires the use of management’s estimates and judgments. Management judgment is required in determining the Company’s worldwide provision for income taxes and recording the related assets and liabilities, including accruals for unrecognized tax benefits and assessing the need for valuation allowances on deferred tax assets. Deferred income taxes are recognized based on the future income tax effects (using enacted tax laws and rates) of differences in the carrying amounts of assets and liabilities for financial reporting and tax purposes. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not (greater than 50 percent) that a tax benefit will not be realized. In evaluating the need for a valuation allowance, we consider all potential sources of taxable income, including income available in carryback periods, future reversals of taxable temporary differences, projections of taxable income, and income from tax planning strategies, as well as all available positive and negative evidence. Positive evidence includes factors such as a history of profitable operations, and projections of future profitability within the carry forward period, including taxable income from tax planning strategies. Negative evidence includes items such as cumulative losses, projections of future losses, or carryforward periods that are not long enough to allow for the utilization of the deferred tax asset based on existing projections of income. Upon changes in facts and circumstances, we may conclude that deferred tax assets for which no valuation allowance is currently recorded may not be realized, resulting in a charge to establish a valuation allowance. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES AND CASH FLOW HEDGES

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES As part of our financial risk management program, we use certain derivative financial instruments. We do not enter into derivative transactions for speculative purposes and, therefore, hold no derivative instruments for trading purposes. We use derivative financial instruments to provide predictability to the effects of changes in foreign exchange rates on our consolidated results. Our objective in managing foreign exchange exposures with derivative instruments is to reduce volatility in cash flow, allowing us to focus more of our attention on business operations.

We account for derivative instruments as a hedge of the related asset, liability, firm commitment or anticipated transaction, when the derivative is specifically designated as a hedge of such items. We measure hedge effectiveness by assessing the changes in the fair value or expected future cash flows of the hedged item. Certain currency forward contracts hedging significant cross-border intercompany loans are considered other derivatives and, therefore, do not qualify for hedge accounting.

CASH FLOW HEDGES Range forward contracts (a transaction where both a put option is purchased and a call option is sold) are designated as cash flow hedges and hedge anticipated cash flows from cross-border intercompany sales of products and services. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss, and are recognized as a component of cost of goods sold when the underlying sale of products or services is recognized into earnings.

NET INVESTMENT HEDGES

NET INVESTMENT HEDGES We designate financial instruments as net investment hedges from time to time to hedge the foreign exchange exposure of our net investment in foreign currency-based subsidiaries. The remeasurements of these non-derivatives designated as net investment hedges are calculated each period with changes reported in foreign currency translation adjustment within accumulated other comprehensive loss. Such amounts will remain in accumulated other comprehensive loss unless we complete or substantially complete liquidation or disposal of our investment in the underlying foreign operations.

CURRENCY TRANSLATION

CURRENCY TRANSLATION Assets and liabilities of international operations are translated into U.S. dollars using year-end exchange rates, while revenues and expenses are translated at average exchange rates throughout the year. The resulting net translation adjustments are recorded as a component of accumulated other comprehensive loss. The local currency is the functional currency of most of our locations.

Losses of $1.6 million, $1.3 million and $4.1 million from currency transactions were included in other income, net in 2026, 2025 and 2024, respectively.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Matters. Various lawsuits arising during the normal course of business are pending against us. In our opinion, the ultimate liability, if any, resulting from these matters will have no significant effect on our consolidated financial position or results of operations. In February 2025, MachiningCloud, Inc. filed a lawsuit against the Company in the Superior Court of the State of California alleging breach of a contract and other matters. The Company removed the case to federal court and asserted counterclaims against MachiningCloud, Inc. MachiningCloud, Inc. initially sought damages in excess of $330 million. During the course of the litigation, certain of MachiningCloud's claims have been narrowed and the damages sought are significantly lower than originally asserted. The Company intends to vigorously defend the action and pursue its counterclaims. At this stage of the litigation, no determination can be made with regard to the outcome of the litigation, including the probability of an unfavorable outcome. Lease Commitments. We lease a wide variety of facilities, primarily for warehousing, production and offices, as well as vehicles and equipment that are considered operating leases. Refer to Note 9 for more information. Purchase Commitments. We have purchase commitments for materials, supplies and machinery and equipment as part of the ordinary conduct of business. Some of these commitments extend beyond one year and are based on minimum purchase requirements. We believe these commitments are not at prices in excess of current market. Other Contractual Obligations. We do not have material financial guarantees or other contractual commitments that are reasonably likely to adversely affect our liquidity. Related Party Transactions. Sales to affiliated companies were immaterial in 2026, 2025 and 2024. We do not have any other related party transactions that affect our operations, results of operations, cash flows or financial condition

Retirement Benefits [Abstract]

PENSION AND OTHER POSTRETIREMENT BENEFITS

Defined Benefit Pension Plans. We have defined benefit pension plans that cover certain employees in the U.S., Germany, the UK, Switzerland, India and Israel. Pension benefits under defined benefit pension plans are based on years of service and, for certain plans, on average compensation for specified years preceding retirement. We fund pension costs in accordance with the funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA), as amended, for U.S. plans and in accordance with local regulations or customs for non-U.S. plans. The accrued benefit for all participants in the Kennametal Inc. Retirement Income Plan was frozen as of December 31, 2016. The majority of our defined benefit pension plans are closed to future participation.

We have an Executive Retirement Plan for certain executives and a Supplemental Executive Retirement Plan both of which were closed to future participation as of June 15, 2017 and July 26, 2006, respectively.

We presently provide varying levels of postretirement health care and life insurance benefits to certain employees and retirees. By fiscal 2019, participants over the age of 65 were transitioned to a private exchange and some received a fixed Health Retirement Account (HRA) contribution to offset the cost of their coverage. Postretirement health and life benefits were closed to future participants as of December 31, 2016.

We use a June 30 measurement date for all of our plans. During 2025, the Company completed the wind-up of its Canadian defined benefit pension plans and recorded a settlement charge of $0.8 million. During 2023 and 2025, the Company annuitized portions of its UK defined benefit pension plans through the purchase of full buy-in policies. The Company expects to progress to a buy-out and an eventual wind-up of the UK plans after completing customary procedures including obtaining relevant regulatory approvals. The wind-up of the UK plans is expected to occur in fiscal 2027.

The funded status of our pension plans and amounts recognized in the consolidated balance sheets as of June 30 were as follows:

Unrecognized net actuarial losses	$	272,996	$	292,946
Unrecognized net prior service costs	1,748		1,762

Total	$	274,744	$	294,708

To the best of our knowledge and belief, the asset portfolios of our defined benefit pension plans do not contain our capital stock. Apart from the annuitization of the UK plans as previously mentioned, we do not issue insurance contracts to cover future annual benefits of defined benefit pension plan participants. The accumulated benefit obligation for all defined benefit pension plans was $629.9 million and $666.0 million as of June 30, 2026 and 2025, respectively.

Included in the above information are plans with accumulated benefit obligations exceeding the fair value of plan assets as of June 30 as follows:

As of June 30, 2026, the projected benefit payments, including future service accruals for these plans for 2027 through 2031, are $59.1 million, $56.9 million, $55.3 million, $54.3 million and $52.7 million, respectively, and $245.8 million in 2032 through 2036.

The amounts of accumulated other comprehensive loss expected to be recognized in net periodic pension cost during 2027 related to net actuarial losses are $11.8 million. The amount of accumulated other comprehensive income expected to be recognized in net periodic pension cost during 2027 related to transition obligations and prior service cost is immaterial.

We expect to contribute approximately $10.0 million to our pension plans in 2027, which is primarily for international plans.

Net periodic other postretirement benefit cost	$	220	$	278	$	312

As of June 30, 2026, the projected benefit payments, including future service accruals for our other postretirement benefit plans for 2027 through 2031, are $0.9 million, $0.8 million, $0.7 million, $0.7 million and $0.6 million, respectively, and $2.4 million in 2032 through 2036.

The amounts of accumulated other comprehensive loss expected to be recognized in net periodic other postretirement benefits cost during 2027 related to net actuarial losses and related to prior service credit are costs of $0.1 million and income of $0.3 million, respectively.

We expect to contribute $0.9 million to our other postretirement benefit plans in 2027.

The service cost component of net periodic pension expense (income) of $1.1 million, $0.9 million and $1.2 million for 2026, 2025 and 2024, respectively, was reported as a component of cost of goods sold and operating expense. The other components of net periodic pension expense (income) and net periodic other postretirement benefit cost totaling a net expense of $6.4 million and $1.3 million for 2026 and 2025, respectively, and a net benefit of $2.9 million for 2024 were presented as a component of other income, net.

Assumptions. The significant actuarial assumptions used to determine the present value of net benefit obligations for our defined benefit pension plans and other postretirement benefit plans were as follows:


	2026	2025	2024
Discount Rate:
U.S. plans	4.8-5.8%	5.0-5.6%	5.7-5.8%
International plans	1.1-6.9%	1.2-6.8%	1.3-7.2%
Rates of future salary increases:
U.S. plans (Executive Retirement Plan only)	4.0%	4.0%	4.0%
International plans	1.5-8.5%	1.5-7.5%	1.8-8.0%

The significant assumptions used to determine the net periodic expense (income) for our pension and other postretirement benefit plans were as follows:


	2026	2025	2024
Discount Rate:
U.S. plans	4.7-5.6%	5.7-5.8%	5.6-6.3%
International plans	1.2-6.8%	1.3-7.2%	1.8-7.3%
Rates of future salary increases:
U.S. plans (Executive Retirement Plan only)	4.0%	4.0%	4.0%
International plans	1.5-7.5%	1.8-8.0%	1.8-8.0%
Rate of return on plans assets:
U.S. plans	6.4%	6.5%	6.3%
International plans	1.3-7.3%	1.3-7.5%	1.8-7.3%

The rates of return on plan assets are based on historical performance, as well as future expected returns by asset class considering macroeconomic conditions, current portfolio mix, long-term investment strategy and other available relevant information.

Plan Assets. The primary objective of certain of our pension plans' investment policies is to ensure that sufficient assets are available to provide the benefit obligations at the time the obligations come due. The overall investment strategy for the defined benefit pension plans' assets combines considerations of preservation of principal and moderate risk-taking. The assumption of an acceptable level of risk is warranted in order to achieve satisfactory results consistent with the long-term objectives of the portfolio. Fixed income securities comprise a significant portion of the portfolio due to their plan-liability-matching characteristics and to address the plans' cash flow requirements. Additionally, diversification of investments within each asset class is utilized to further reduce the effect of losses in single investments.

Investment management practices for U.S. defined benefit pension plans must comply with ERISA and all applicable regulations and rulings thereof. The use of derivative instruments is permitted where appropriate and necessary for achieving overall investment policy objectives. Currently, the use of derivative instruments is not significant when compared to the overall investment portfolio.

The Company utilizes a liability driven investment strategy (LDI) for the assets of its U.S. defined benefit pension plans in order to reduce the volatility of the funded status of these plans and to meet the obligations at an acceptable cost over the long term. This LDI strategy entails modifying the asset allocation and duration of the assets of the plans to more closely match the liability profile of these plans. The asset reallocation involves increasing the fixed income allocation, reducing the equity component and adding alternative investments. Longer duration interest rate swaps have been utilized periodically in order to increase the overall duration of the asset portfolio to more closely match the liabilities.

Our defined benefit pension plans’ asset allocations as of June 30, 2026 and 2025 and target allocations for 2027, by asset class, were as follows:


	2026		2025		Target %
Equity	12	%	13	%	13	%
Fixed Income	74		72		72
Other	14		15		15

The following sections describe the valuation methodologies used to measure the fair value of the defined benefit pension plan assets, including an indication of the level in the fair value hierarchy in which each type of asset is generally classified (see Note 5 for the definition of fair value and a description of the fair value hierarchy).

Corporate fixed income securities. Investments in corporate fixed income securities consist of corporate debt and asset backed securities. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, swap curve and yield curve.

Common stock. Common stocks are classified as level one and are valued at their quoted market price.

Government securities. Investments in government securities consist of fixed income securities such as U.S. government and agency obligations and foreign government bonds and asset and mortgage backed securities such as obligations issued by government sponsored organizations. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, credit spreads and interest rates.

Other fixed income securities Investments in other fixed income securities are classified as level two and valued based on observable market data.

Other. Other investments consist primarily of state and local obligations and short term investments including cash, corporate notes, and various short term debt instruments which can be redeemed within a nominal redemption notice period. These investments are primarily classified as level two and are valued using independent observable market inputs.

The fair value methods described may not be reflective of future fair values. Additionally, while the Company believes the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in different fair value measurement at the reporting date.

The following table presents the fair value of the benefit plans' assets by asset category as of June 30, 2026:

Defined Contribution Plans. We sponsor several defined contribution retirement plans. Costs for defined contribution plans were $16.3 million, $16.5 million and $16.3 million in 2026, 2025 and 2024, respectively.

Certain U.S. employees are eligible to participate in the Kennametal Thrift Plus Plan (Thrift), which is a qualified defined contribution plan under section 401(k) of the Internal Revenue Code. Under the Thrift, eligible employees receive a full match of their contributions up to 6 percent of eligible compensation.

All contributions, including the company match and discretionary, are made in cash and invested in accordance with participants’ investment elections. There are no minimum amounts that must be invested in company stock, and there are no restrictions on transferring amounts out of company stock to another investment choice, other than excessive trading rules applicable to such investments. Employee contributions and our matching and discretionary contributions vest immediately as of the participants' employment dates.

Total long-term debt	$	685,280	$	596,788

In May 2026, the Company completed refinancing transactions designed to enhance liquidity, extend debt maturities and increase financial flexibility. The Company issued $300.0 million of 5.800% Senior Unsecured Notes due 2036 (the "2036 Notes"). Interest is paid semi-annually on May 28 and November 28 of each year. Net proceeds from the 2036 Notes were used to fund a tender offer for the Company's outstanding 4.625 percent Senior Unsecured Notes due 2028 (the "2028 Notes"). The tender offer resulted in the repurchase of $209.4 million out of the total $300.0 million aggregate principal of the 2028 Notes.

In connection with these transactions, the Company also entered into a new $500.0 million three-year term loan and amended its Credit Agreement (as defined in Note 12) to increase aggregate commitments by $200.0 million. The Company expects to have fully drawn the $500.0 million term loan by September 30, 2026, after which any undrawn commitments will no longer be available.

In February 2021, we issued $300.0 million of 2.800 percent Senior Unsecured Notes with a maturity date of March 1, 2031. Interest is paid semi-annually on March 1 and September 1 of each year.

As of June 30, 2026, the future principal maturities of long-term debt are $90.6 million in 2028, $300.0 million in 2031 and $300.0 million in 2036. The 2028 Notes were fully redeemed on July 1, 2026.

Fixed rate debt had a fair market value of $666.7 million and $570.8 million at June 30, 2026 and 2025, respectively. The Level 2 fair value is determined based on the quoted market prices for similar debt instruments as of June 30, 2026 and 2025, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

As part of our financial risk management program, we use certain derivative financial instruments. See Note 2 for discussion on our derivative instruments and hedging activities policy.

The fair value of derivatives designated and not designated as hedging instruments in the consolidated balance sheets are as follows:


(in thousands)	2026		2025
Derivatives designated as hedging instruments

Other current liabilities - range forward contracts	$	—	$	(9)




Total derivatives designated as hedging instruments	—		(9)



Derivatives not designated as hedging instruments
Other current assets - currency forward contracts	$	32	$	88
Other current liabilities - currency forward contracts	(213)		(72)
Total derivatives not designated as hedging instruments	(181)		16
Total derivatives	$	(181)	$	7

Certain currency forward contracts that hedge significant cross-border intercompany loans are considered as other derivatives and therefore do not qualify for hedge accounting. These contracts are recorded at fair value in the consolidated balance sheets, with the offset to other income, net. Losses (gains) related to derivatives not designated as hedging instruments have been recognized as follows:


(in thousands)	2026		2025		2024
Loss (gain) recognized in other income, net	$	282	$	(58)	$	69

CASH FLOW HEDGES

Range forward contracts (a transaction where both a put option is purchased and a call option is sold) are designated as cash flow hedges and hedge anticipated cash flows from cross-border intercompany sales of products and services. Gains and losses realized on these contracts are recorded in accumulated other comprehensive loss and are recognized as a component of cost of goods sold when the underlying sale of products or services is recognized into earnings. The notional amount of the contracts translated into U.S. dollars at June 30, 2026 and 2025 was zero and $4.7 million, respectively. The time value component of the fair value of range forward contracts is excluded from the assessment of hedge effectiveness.

The following represents (losses) gains, net of tax, related to cash flow hedges:


(in thousands)	2026		2025
Unrealized (loss) gain recognized in other comprehensive income (loss)	$	(207)	$	771

NET INVESTMENT HEDGES

As of June 30, 2026 and 2025, we had certain foreign currency-denominated intercompany loans payable with total aggregate principal amounts of ¥321.4 million and ¥82.3 million, respectively, designated as net investment hedges to hedge the foreign exchange exposure of our net investment in our China-based subsidiaries. Losses of $1.6 million and $2.2 million were recorded as a component of foreign currency translation adjustments in other comprehensive (loss) income as of June 30, 2026 and 2025, respectively.

As of June 30, 2026, the foreign currency-denominated intercompany loans payable designated as net investment hedges consisted of:


Instrument	Notional (CNY in thousands)(2)		Notional (USD in thousands)(2)		Maturity

Foreign currency-denominated intercompany loan payable	¥	87,611	$	12,910	January 2027




Foreign currency-denominated intercompany loan payable	¥	69,658	$	10,264	February 2027
Foreign currency-denominated intercompany loan payable	¥	123,069	$	18,134	March 2027
Foreign currency-denominated intercompany loan payable	¥	41,065	$	6,051	May 2027

Debt Disclosure [Abstract]

SUPPLIER FINANCE PROGRAM

We have a supplier finance program managed through two global financial institutions under which we agree to pay the financial institutions the stated amount of confirmed invoices from our participating suppliers on the invoice due date. We, or the global financial institutions, may terminate our agreements at any time upon 30 days written notice. We do not provide any forms of guarantees under these agreements. Supplier participation in the program is solely up to the supplier. We have no economic interest in a supplier’s decision to participate in the program, and their participation has no bearing on our payment terms or amounts due. The payment terms that we have with our suppliers under this program are considered commercially reasonable. As of June 30, 2026 and 2025, the obligations outstanding that the Company has confirmed as valid to the financial institutions under the program were $96.8 million and $17.3 million, respectively, and were recorded within trade accounts payable. Obligations outstanding under the supplier finance program increased during 2026 primarily due to higher purchasing activity as well as an increase in the program capacity.

The following rollforward table indicates the Company's outstanding obligations under the supplier finance program for the year ended June 30, 2026:

During 2024, we recorded a tax benefit of $7.8 million to record the effects of a tax rate increase enacted by the cantonal and municipal tax authorities where we operate in Switzerland. The impact of this item is included in the tax reconciliation table under the caption "Combined effects of Swiss tax reform."

During 2024, we recorded a tax benefit of $6.2 million to reduce an accrual for an unrecognized tax benefit due to the lapse of the statute of limitation. The impact of this item is included in the tax reconciliation table under the caption "Change in valuation allowance and other uncertain tax positions."

During 2024, we recorded a tax charge of $2.9 million to settle income tax litigation in Italy. The impact of this item is included in the tax reconciliation table under the caption "Change in valuation allowance and other uncertain tax positions."

The components of net deferred tax assets and liabilities were as follows at June 30:


(in thousands)	2026		2025
Deferred tax assets:
Net operating loss (NOL) carryforwards	$	16,028	$	19,756

Total	92,361		140,225
Valuation allowance	4,946		6,214
Total deferred tax assets	$	87,415	$	134,011
Deferred tax liabilities:
Tax depreciation in excess of book	$	46,068	$	53,337
Operating lease right-of-use assets	11,467		10,710

Unremitted earnings not permanently reinvested	6,795		3,754
Pension benefits	9,362		3,882
Other	3,459		4,464
Total deferred tax liabilities	$	77,151	$	76,147
Total net deferred tax assets	$	10,264	$	57,864

Included in deferred tax assets at June 30, 2026 is $1.0 million associated with tax credits and other carryforward items in the U.S. and Europe. Of that amount, $0.2 million expires through 2046, and $0.8 million does not expire.

Included in deferred tax assets at June 30, 2026 is $16.0 million associated with NOL carryforwards in U.S. state and foreign jurisdictions. Of that amount, $1.6 million expires through 2031, $0.5 million expires through 2036, $0.6 million expires through 2041, $2.5 million expires through 2046, and the remaining $10.8 million does not expire. The realization of these tax benefits is primarily dependent on future taxable income in these jurisdictions.

A valuation allowance of $4.9 million has been placed against deferred tax assets primarily in U.S. state, Hong Kong and Vietnam jurisdictions, all of which would be allocated to income tax expense upon realization of the deferred tax assets. As the respective operations generate sufficient income, the valuation allowances will be partially or fully reversed at such time we believe it will be more likely than not that the deferred tax assets will be realized. In 2026, the valuation allowance related to these deferred tax assets decreased by $1.3 million.

We consider the majority of the $1.1 billion unremitted earnings of our non-U.S. subsidiaries to be permanently reinvested. With regard to these unremitted earnings, we have not, nor do we anticipate the need to, repatriate funds to the U.S. to satisfy domestic liquidity needs arising in the ordinary course of business, including liquidity needs associated with our domestic debt service requirements. Determination of the amount of unrecognized deferred tax liability related to indefinitely reinvested earnings is not practicable due to our legal entity structure and the complexity of U.S. and local tax laws. With regard to the small portion of unremitted earnings that are not indefinitely reinvested, we maintain a deferred tax liability for foreign withholding and U.S. state income taxes. The deferred tax liability associated with unremitted earnings of our non-U.S. subsidiaries not permanently reinvested is $6.8 million as of June 30, 2026.

A reconciliation of the beginning and ending amount of unrecognized tax benefits (excluding interest and penalty) is as follows as of June 30:


(in thousands)	2026		2025		2024
Balance at beginning of year	$	1,694	$	1,309	$	6,935
Increases for tax positions of prior years	1,302		316		—

Increases for tax positions related to the current year	336		77		79

Decreases related to lapse of statute of limitations	(75)		(140)		(5,686)
Foreign currency translation	(79)		132		(19)
Balance at end of year	$	3,178	$	1,694	$	1,309

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate in 2026, 2025 and 2024 is $3.2 million, $1.7 million and $1.3 million, respectively.

Our policy is to recognize interest and penalties related to income taxes as a component of the provision for income taxes in the consolidated statements of income. We recognized an increase of $0.7 million and $0.1 million in 2026 and 2025, respectively and a decrease of $0.9 million in 2024. As of June 30, 2026 and 2025, the amount of penalty accrued was $0.1 million.

With few exceptions, we are no longer subject to income tax examinations by tax authorities for years prior to 2019. The Internal Revenue Service has audited, or the statute of limitations has expired, for all U.S. tax years prior to 2023. Various state and foreign jurisdiction tax authorities are in the process of examining our income tax returns for various tax years ranging from 2019 to 2024. We continuously review our uncertain tax positions and evaluate any potential issues that may lead to an increase or decrease in the total amount of unrecognized tax benefits recorded.

Losses of $1.6 million, $1.3 million and $4.1 million from currency transactions were included in other income, net in 2026, 2025 and 2024, respectively.

TARIFFS The Company is monitoring developments related to certain tariffs imposed under the International Emergency Economic Powers Act (IEEPA) that may result in future refunds of previously paid tariffs. Any potential recoveries are accounted for as gain contingencies and will not be recognized until realized or otherwise deemed realizable. As of June 30, 2026, refunds received were not material, and the Company had not recorded any related receivables. The Company has not recorded any liabilities associated with potential tariff recoveries, as any refunds received are expected to be reinvested in the business and no obligation to reimburse customers existed as of June 30, 2026. Any future recoveries will be recognized when the applicable accounting criteria is met.

Environmental Matters	Jun. 30, 2026
Environmental Remediation Obligations [Abstract]
ENVIRONMENTAL MATTERS	ENVIRONMENTAL MATTERS The operation of our business has exposed us to certain liabilities and compliance costs related to environmental matters. We are involved in various environmental cleanup and remediation activities at certain sites associated with our current or former operations. We establish and maintain accruals for estimated liabilities associated with certain environmental matters. At June 30, 2026, the balance of such accruals was $12.3 million, of which $2.7 million was current. At June 30, 2025, the balance was $11.0 million, of which $1.4 million was current. These accruals are generally not discounted. We record a loss contingency when the available information indicates it is probable that we have incurred a liability and the amount of the loss is reasonably estimable. The likelihood of a loss with respect to a particular environmental matter is often difficult to predict, and determining a meaningful estimate of the loss or a range of loss may not be practicable based on information available. When a material loss contingency is probable but a reasonable estimate cannot be made, or when a material loss contingency is at least reasonably possible, disclosure is provided. The accruals we have established for estimated environmental liabilities represent our best current estimate of the probable and reasonably estimable costs of addressing identified environmental situations, based on our review of currently available evidence, and taking into consideration our prior experience in remediation and that of other companies, as well as public information released by the United States Environmental Protection Agency (USEPA), other governmental agencies and by the Potentially Responsible Party (PRP) groups in which we are participating. The accrued liabilities for all environmental concerns could change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, technological changes, discovery of new information, the financial strength of other PRPs, the identification of new PRPs and the involvement of and direction taken by the government or the courts on these matters. Among other environmental laws, we are subject to the Comprehensive Environmental Response Compensation and Liability Act of 1980 (CERCLA), under which we have been identified by the USEPA or other third party as a PRP with respect to environmental remedial costs at certain Superfund sites. We have evaluated our claims and estimated liability associated with these sites based upon the best information currently available to us. We believe our environmental accruals are adequate to cover our portion of the environmental remedial costs at the sites where we have been designated a PRP, to the extent these expenses are probable and reasonably estimable.

- Definition

The entire disclosure for environmental loss contingencies, such as presence of hazardous waste, relevant information from reports issued by regulators, and estimated costs to achieve compliance with regulatory requirements. This element may be used for all of an entity's disclosures about environmental loss contingencies.

Financial Instruments	Jun. 30, 2026
Debt Instrument, Fair Value Disclosure [Abstract]
FINANCIAL INSTRUMENTS	FINANCIAL INSTRUMENTS The methods used to estimate the fair value of our financial instruments are as follows: Cash and Cash Equivalents, Revolving and Other Lines of Credit and Notes Payable. The carrying amounts approximate their fair value because of the short maturity of the instruments. Long-Term Debt, Including Current Maturities. Fixed rate debt had a fair market value of $666.7 million and $570.8 million at June 30, 2026 and 2025, respectively. The Level 2 fair value is determined based on the quoted market prices for similar debt instruments as of June 30, 2026 and 2025, respectively. Concentrations of Credit Risk. Financial instruments that potentially subject us to concentrations of credit risk consist primarily of temporary cash investments and trade receivables. By policy, we make temporary cash investments with high credit quality financial institutions and limit the amount of exposure to any one financial institution. With respect to trade receivables, concentrations of credit risk are significantly reduced because we serve numerous customers in many industries and geographic areas. We are exposed to counterparty credit risk for nonperformance of derivatives and, in the unlikely event of nonperformance, to market risk for changes in interest and currency exchange rates, as well as settlement risk. We manage exposure to counterparty credit risk through credit standards, diversification of counterparties and procedures to monitor concentrations of credit risk. We do not anticipate nonperformance by any of the counterparties. As of June 30, 2026 and 2025, we had no significant concentrations of credit risk.

Leases [Abstract]

LEASES

At the inception of our contracts, we determine if the contract is or contains a lease. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. ROU assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement. For leases that do not have a readily determinable implicit rate, we use a discount rate based on our incremental borrowing rate, which is determined considering factors such as the lease term, our credit rating and the economic environment of the location of the lease as of the commencement date.

We account for non-lease components separately from lease components. These costs often relate to the payments for a proportionate share of real estate taxes, insurance, common area maintenance and other operating costs in addition to base rent. We also generally do not recognize ROU assets and liabilities for leases with an initial term of 12 months or less. Lease costs associated with leases of less than 12 months were $8.2 million, $7.7 million and $5.9 million for the years ended June 30, 2026, 2025 and 2024, respectively.

As a lessee, we have various operating lease agreements primarily related to real estate, vehicles and office and plant equipment. Our real estate leases, which are comprised primarily of manufacturing, warehousing, office and administration facilities, represent a majority of our lease liability. Our lease payments are largely fixed. Any variable lease payments, including utilities, common area maintenance and repairs and maintenance, are expensed during the period incurred. Variable lease costs were immaterial for the years ended June 30, 2026, 2025 and 2024. A majority of our real estate leases include options to extend the lease and options to early terminate the lease. Leases with an early termination option generally involve a termination payment. We review all options to extend, terminate, or purchase the ROU assets at the inception of the lease and account for these options when they are reasonably certain of being exercised. Our lease agreements generally do not contain any material residual value guarantees or materially restrictive covenants. We have signed a material lease agreement related to the Company's future innovation center in Germany. The lease has not yet commenced as the facility has yet to be constructed and the Company does not have the right to use the property until the future handover date. We do not have any material lease transactions with related parties.

Operating lease expense is recognized on a straight-line basis over the lease term and is included in operating expense on our consolidated statements of income. Operating lease cost was $24.1 million, $24.3 million and $22.3 million in 2026, 2025 and 2024, respectively.

The following table sets forth supplemental balance sheet information related to our operating leases:

Share-Based Payment Arrangement [Abstract]

STOCK-BASED COMPENSATION

Stock Options. Changes in our stock options for 2026 were as follows:


	Options	Weighted Average Exercise Price		Weighted Average Remaining Life (years)	Aggregate Intrinsic value (in thousands)
Options outstanding, June 30, 2025	101,947	$	30.20

Exercised	(14,000)	20.87
Lapsed and forfeited	(87,947)	31.69
Options outstanding, June 30, 2026	—	$	—	0.0	$	—
Options vested and expected to vest, June 30, 2026	—	$	—	0.0	$	—
Options exercisable, June 30, 2026	—	$	—	0.0	$	—

As of June 30, 2026 and 2025, there was no unrecognized compensation cost related to options outstanding. All options were fully vested as of June 30, 2026 and 2025.

Tax benefits relating to excess stock-based compensation deductions are presented in the consolidated statements of cash flows as operating cash inflows. Tax benefits resulting from stock-based compensation deductions were less than the amounts reported for financial reporting purposes by $0.8 million, $0.8 million and $1.5 million in 2026, 2025 and 2024, respectively.

The amount of cash received from the exercise of capital stock options during 2026, 2025 and 2024 was zero. The related tax benefit was $0.1 million in 2026, and zero in 2025 and 2024. The total intrinsic value of options exercised in 2026 was $0.2 million, and zero in 2025 and 2024.

Restricted Stock Units – Time Vesting and Performance Vesting. Performance vesting restricted stock units are earned based on both annual and three-year performance targets. The performance vesting restricted stock units are subject to a service condition that requires the individual to be employed by the Company at the payment date after a three-year period, with the exception of retirement eligible grantees. Time vesting stock units are valued at the market value of the stock on the grant date. Performance vesting stock units with a market condition are valued using a Monte Carlo model.

Changes in our performance vesting and time vesting restricted stock units for 2026 were as follows:


	Performance Vesting Stock Units	Performance Vesting Weighted Average Fair Value		Time Vesting Stock Units	Time Vesting Weighted Average Fair Value
Unvested, June 30, 2025	568,332	$	24.76	1,197,215	$	25.50
Granted	365,215	21.04		1,167,710	21.19
Vested	(244,574)	27.15		(681,656)	25.53
Performance metric adjustments, net	(38,930)	26.28		—	—

Forfeited	(5,536)	22.95		(50,803)	23.16
Unvested, June 30, 2026	644,507	$	21.66	1,632,466	$	22.48

During 2026, 2025 and 2024, compensation expense related to performance vesting and time vesting restricted stock units was $33.4 million, $21.0 million and $23.4 million, respectively. Performance vesting stock units were adjusted by 38,930 units during 2026 related to the fiscal 2025 performance year. As of June 30, 2026, the total unrecognized compensation cost related to unvested performance vesting and time vesting restricted stock units was $24.8 million and is expected to be recognized over a weighted average period of 1.5 years.

Notes Payable and Lines of Credit [Abstract]
REVOLVING AND OTHER LINES OF CREDIT AND NOTES PAYABLE	NOTE 12 — REVOLVING AND OTHER LINES OF CREDIT AND NOTES PAYABLE During fiscal 2026, we entered into the Seventh Amended and Restated Credit Agreement dated as of November 17, 2025 (the Credit Agreement). The Credit Agreement is a five-year, multi-currency, revolving credit facility, which we use to augment cash from operations and as an additional source of funds. The Credit Agreement allows for borrowings in U.S. dollars, Canadian dollars, euros, pounds sterling and Japanese yen. Interest payable under the Credit Agreement is based upon the type of borrowing under the facility and may be (1) Euro Interbank Offered Rate (EURIBOR), Sterling Overnight Index Average (SONIA), Canadian Overnight Repo Rate Average (CORRA), Tokyo Interbank Offered Rate (TIBOR) and Secured Overnight Financing Rate (SOFR) for any borrowings in euros, pounds sterling, Canadian dollars, yen and U.S. dollars, respectively, plus an applicable margin, (2) the greater of the prime rate or the Federal Funds effective rate plus an applicable margin, or (3) fixed as negotiated by us. The Credit Agreement matures in November 2030. The Credit Agreement requires us to comply with various restrictive and affirmative covenants, including one financial covenant: a maximum leverage ratio where debt, net of domestic cash and sixty percent of the unrestricted cash held outside of the United States, must be less than or equal to 3.75 times trailing twelve months EBITDA, adjusted for certain non-cash expenses. In May 2026, in connection with the refinancing transactions more fully described in Note 11, the Company amended its Credit Agreement to increase aggregate commitments by $200.0 million for a total of $850.0 million. As of June 30, 2026 and 2025, we were in compliance with all covenants of the Credit Agreement. As of June 30, 2026, we had $20 million of borrowings outstanding and $830.0 million of availability. There were no borrowings outstanding as of June 30, 2025. The weighted average interest rate on borrowings under the Credit Agreement was 4.7 percent for the year ended June 30, 2026. Borrowings on other lines of credit and notes payable were $12.2 million and $1.0 million at June 30, 2026 and 2025, respectively. The lines of credit represented short-term borrowings under credit lines with commercial banks in the various countries in which we operate. The availability of these credit lines, translated into U.S. dollars at June 30, 2026 exchange rates, totaled $48.8 million.
