Basis of Presentation:

The accompanying consolidated financial statements of Materion Corporation and its subsidiaries (referred to herein as the Company, our, we, or us) contain all of the adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods reported. All adjustments were of a normal and recurring nature.

These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company's 2025 Annual Report on Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year.

New Accounting Guidance Issued and Not Yet Adopted:

In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses," which is intended to improve disclosures about a public business entity's expenses and address requests from investors for more detailed information about the types of expenses in commonly presented expense captions. Such information should allow investors to better understand an entity's performance, assess future cash flows, and compare performance over time and with other entities. The amendments will require public business entities to disclose in the notes to the financial statements, at each interim and annual reporting period, specific information about certain costs and expenses, including purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each expense caption presented on the face of the income statement, and the total amount of an entity's selling expenses. The amendments are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and may be applied either prospectively or retrospectively. Early adoption is permitted. While the adoption of ASU 2024-03 will result in enhanced disclosures, the Company does not expect it will have a material impact on its financial condition or results of operations.

In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-internal-use software (Subtopic 350-40): Targeted Improvements to the Accounting for internal-use software. The amendments in this ASU make targeted improvements to Subtopic 350-40, Intangibles-Goodwill and Other-internal-use software, to increase the operability of the recognition guidance considering different methods of software development. This ASU is effective for fiscal years beginning after December 15, 2027, and interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this ASU will have on its condensed consolidated financial statements and related disclosures.

In December 2025, the FASB issued 2025‑10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. This ASU establishes comprehensive U.S. GAAP guidance for the recognition, measurement, and presentation of government grants received by business entities. The amendments incorporate principles similar to those in International Accounting Standards (IAS) 20 and are intended to reduce diversity in practice by providing a consistent framework for accounting for monetary and tangible nonmonetary government grants. This ASU is effective for fiscal years beginning after December 15, 2028, and interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this ASU will have on its condensed consolidated financial statements and related disclosures.

On July 9, 2025, the Company completed the acquisition of certain manufacturing assets for tantalum solutions in Dangjin City, South Korea, from Konasol Co., Ltd., a Korean manufacturer serving the semiconductor and adjacent markets. This

strategic investment expands the Company’s global footprint with a facility in Asia to better serve semiconductor customers in that region.

The total purchase price was approximately $19.5 million, which was paid in cash on the date of acquisition. The acquisition and related fees and expenses were funded through available cash and borrowings under the Company's revolving credit facility. Acquisition-related transaction and integration costs totaled $1.8 million in 2025 with no material costs incurred in 2026. These costs are included in selling, general, and administrative expenses in the Consolidated Statements of Income.

The Company accounted for the transaction as a business combination using the acquisition method of accounting and a third-party valuation appraisal, and included the results of operations of the acquisition in its consolidated financial statements from the effective date of the acquisition. The operating results are included within the Company's Electronic Materials segment. Pro forma financial information has not been presented, as revenue and expenses related to the acquisition do not have a material impact on the Company’s consolidated financial statements.

The total purchase price was allocated to identifiable assets and liabilities based upon the preliminary estimates of fair value at the date of the acquisition, which primarily included property, plant and equipment, and a developed technology intangible asset of $2.1 million. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill and approximated $14.9 million. The goodwill is deductible for Korean tax purposes. The fair value of the acquired intangible asset is determined based on an income approach, using estimates and assumptions that are deemed reasonable by the Company. These assumptions are subject to revision as additional information is obtained about the facts and circumstances that existed as of the acquisition date, primarily related to intangible assets, which may result in adjustments to the preliminary values discussed above as valuations are finalized. No material provisional adjustments to the acquisition accounting have been recorded during 2026. We expect to finalize these amounts as soon as possible, but no later than the end of the third quarter of 2026.

 

The Company has the following reportable segments: Performance Materials, Electronic Materials, Precision Optics, and Other. The Company’s reportable segments represent components of the Company for which separate financial information is available that is utilized on a regular basis by the Chief Executive Officer, the Company's chief operating decision maker, in determining how to allocate the Company’s resources and evaluate performance.

Performance Materials provides advanced engineered solutions comprised of beryllium and non-beryllium containing alloy systems and custom engineered parts in strip, bulk, rod, plate, bar, tube, and other customized shapes.

Electronic Materials produces advanced chemicals, microelectric packaging, precious metal, non-precious metal, and specialty metal products, including vapor deposition targets, frame lid assemblies, clad and precious metal preforms and high temperature braze materials.

Precision Optics produces thin film coatings, optical filter materials, sputter-coated, and precision-converted thin film materials.

The Other reportable segment includes unallocated corporate costs and assets.

The primary measurement used by management to measure the financial performance of each segment is earnings before interest, taxes, depreciation and amortization (EBITDA). The below table presents financial information for each segment and a reconciliation of EBITDA to Net Income (the most directly comparable GAAP financial measure) for the second quarter and first six months of 2026 and 2025:

Net sales consist primarily of revenue from the sale of precious and non-precious specialty metals, beryllium and copper-based alloys, beryllium composites, and other products into numerous end markets. The Company requires an agreement with a customer that creates enforceable rights and performance obligations. The Company generally recognizes revenue in an amount that reflects the consideration to which it expects to be entitled upon satisfaction of a performance obligation by transferring control over a product to the customer. Control over a product is generally transferred to the customer when the Company has a present right to payment, the customer has legal title, the customer has physical possession, the customer has the significant risks and rewards of ownership, and/or the customer has accepted the product.

Transaction Price Allocated to Future Performance Obligations: Accounting Standards Codification 606, Revenue from Contracts with Customers, requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied at July 3, 2026. Remaining performance obligations include non-cancelable purchase orders and customer contracts. The guidance provides certain practical expedients that limit this requirement. As such, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

After considering the practical expedient at July 3, 2026 and December 31, 2025, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $116.4 million and $21.9 million, respectively.

Contract Balances: The timing of revenue recognition, billings, and cash collections resulted in the following contract assets and contract liabilities:

(Thousands)						July 3, 2026						December 31, 2025						$ change						% change
Accounts receivable, trade						$	261,405					$	223,763					$	37,642					17		%
Unbilled receivables						55,427						46,548						8,879						19		%
Unearned revenue						12,271						12,685						(414)						(3)		%

Accounts receivable, trade represents payments due from customers relating to the transfer of the Company’s products and services. The Company believes that its receivables are collectible and appropriate allowances for doubtful accounts have been recorded. Impairment losses (bad debt) incurred related to our receivables were immaterial during the second quarter and first six months of 2026.

During 2024, the Company entered into a factoring agreement to sell certain receivables to a third-party financial institution. The transfer of the receivables constitute purchases and sales of receivables resulting in a reduction of trade receivables on the consolidated balance sheets and the proceeds are included in the cash flows from operating activities in the consolidated statements of cash flows. The Company did not sell any receivables in the second quarter of 2026. The company sold a total of $8.1 million of receivables resulting in a loss on sale of $0.1 million for the first six months of 2026. The Company sold a total of $59.4 million of receivables in 2025. The Company did not sell any receivables in the fourth quarter of 2025. Total receivables sold under this program amount to $116.4 million

Unbilled receivables represent expenditures on contracts, plus applicable profit margin, not yet billed. Unbilled receivables are generally billed and collected within one year. Billings made on contracts are recorded as a reduction of unbilled receivables.

Unearned revenue is recorded for consideration received from customers in advance of satisfaction of the related performance obligations. The Company recognized approximately $6.9 million of the December 31, 2025 unearned amounts as revenue during the first six months of 2026.

As a practical expedient, the Company does not adjust the promised amount of consideration for the effects of a significant financing component because the period between the transfer of a product or service to a customer and when the customer pays for that product or service will be one year or less. The Company does not include extended payment terms in its contracts with customers.

Other-net for the second quarter and first six months of 2026 and 2025 is summarized as follows:

In fiscal years 2025 and 2024, we announced restructuring plans that were both designed to reduce costs and expenses in response to macroeconomic conditions and current operating performance. These actions impacted all three of our business segments as well as Corporate. The restructuring programs are expected to result in the reduction in annual cost of sales and operating expenses.

In 2026, the Company continued to implement restructuring actions across all segments. In connection with these actions, we recorded restructuring expenses of $0.3 million and $2.6 million in the three and six months ended July 3, 2026, respectively, compared to $0.5 million and $2.5 million in the three and six months ended June 27, 2025, respectively. All of these charges were associated with workforce reduction, including severance and other personnel-related costs. As of the July 3, 2026, we have substantially completed the restructuring activities expected for the fiscal year 2026.

The activity in the accrued balances incurred in relation to restructuring during the six months ended July 3, 2026 and June 27, 2025, were as follows:

The Company's effective tax rate for the second quarter of 2026 and 2025 was 12.9% and 13.8%, respectively, and 11.1% and 14.5% for the first six months of 2026 and 2025, respectively. The effective tax rate for 2026 is lower than the statutory tax rate primarily due to the impact of the foreign-derived deduction eligible income and percentage depletion. The effective tax rate for for 2025 was lower than the statutory tax rate primarily due to the impact of percentage depletion and the advanced manufacturing production credit. The effective tax rate for the first six months of 2026 included a $4.6 million net discrete income tax benefit, which primarily consists of $2.4 million excess tax benefits from stock-based compensation awards, a $1.1 million tax benefit from the release of a valuation allowance previously recorded against the deferred tax assets of one of the Company’s foreign subsidiaries, and a net $0.5 million tax benefit from a Liechtenstein tax review settlement as noted below. The effective tax rate for the first six months of 2025 included a net discrete income tax benefit of $0.6 million, which primarily consisted of $0.2 million of expense for stock-based compensation awards and $0.4 million expense for unrecognized tax benefits.

In the second quarter of 2026, the Company completed a tax review with the Liechtenstein tax authorities for tax years 2020 through 2023, resulting in a settlement related to an intercompany loan impairment that reduced net operating loss carryforwards by $2.5 million. Upon completion of the review, the Company released a $3.0 million uncertain tax position, which was partially offset by a related tax assessment and resulted in a $0.5 million net discrete tax benefit.

Government Tax Credits

Pursuant to The Inflation Reduction Act of 2022 (IRA), the Company is eligible for the Advanced Manufacturing Production Credit (production credit). The production credit provides an annual cash benefit for a portion of the production costs for the sale of certain critical minerals produced in the U.S. and sold during the year. The Company records the production credit as a reduction in cost of goods sold as the applicable items are produced and sold. U.S. GAAP does not address the accounting for government grants received by a business entity that are outside the scope of ASC 740. Our accounting policy is to analogize to IAS 20, Accounting for Government Grants and Disclosure of Government Assistance, under IFRS Accounting Standards. We recognize the benefit of the production credit by applying IAS 20 in pretax income on a systematic basis in line with its recognition of the expenses that the grant is intended to compensate.

Pillar Two

The Organization for Economic Co-operation and Development (OECD) introduced rules to establish a global minimum corporate tax rate, commonly referred to as Pillar Two. Many of the key non-U.S. jurisdictions where the Company operates have enacted Pillar Two legislation. While the U.S. has negotiated a “side-by-side” arrangement for the existing U.S. minimum taxes with the intent to exempt U.S. multinational companies from certain Pillar Two provisions, the timing and consistency of implementation across jurisdictions continue to evolve. As more countries adopt the “side-by-side” provisions in 2026, the Company’s Pillar Two tax expense will decrease accordingly. We will continue to evaluate the impact of future Pillar Two legislation on the Company’s effective tax rate.

In 2020, the Company entered into an investment agreement and a master supply agreement with a customer to procure equipment to manufacture product for the customer. The customer provided prepayments to the Company to fund the necessary infrastructure improvements and procure the equipment necessary to supply the customer with the desired product. The Company owns, operates and maintains the equipment that is being used to manufacture product for the customer.

Revenue will be recognized as the Company fulfills purchase orders and ships the commercial product to the customer, as product delivery is considered the satisfaction of the performance obligation.

Additionally, during the second quarter of 2022, the Company entered into an amendment to the investment agreement with the same customer to procure additional equipment to manufacture product for the customer. In 2023, the Company received the remaining prepayments related to this amendment, the total of which approximated $38.6 million.

As of July 3, 2026 and December 31, 2025, $41.1 million and $47.5 million, respectively, of prepayments are classified as Unearned income on the Consolidated Balance Sheets. The prepayments will remain in Unearned income until commercial purchase orders are received for product serviced out of the equipment, at which time a portion of the purchase order value related to prepayments will be reclassified to Unearned revenue. As of July 3, 2026 and December 31, 2025, $1.8 million and $2.4 million of the prepayments are classified as Unearned revenue.

Stock-based compensation expense, which includes awards settled in shares was $5.2 million and $8.6 million in the second quarter and first six months of 2026, respectively, compared to $2.6 million and $5.6 million, respectively, in the same periods of 2025.

The Company granted 47,436 SARs to certain employees during the first six months of 2026. The weighted-average exercise price per share and weighted-average fair value per share of the SARs granted during the six months ended July 3, 2026 were $166.59 and $56.70, respectively. The Company estimated the fair value of the SARs using the following weighted-average assumptions in the Black-Scholes model:

Risk-free interest rate						3.62		%
Dividend yield						0.34		%
Volatility						34.0		%
Expected term (in years)						4.8

The Company granted 93,035 stock-settled RSUs to certain employees during the first six months of 2026. The Company measures the fair value of stock-settled RSUs based on the closing market price of a share of Materion common stock on the date of the grant. The weighted-average fair value per share was $161.67 for stock-settled RSUs granted to employees during the six months ended July 3, 2026. RSUs are generally expensed over the vesting period of three years for employees.

The Company granted stock-settled performance-based restricted stock units (PRSUs) to certain employees in the first six months of 2026. The weighted-average fair value of the stock-settled PRSUs was $206.28 per share and will be expensed over the vesting period of three years. The final payout to the employees for all PRSUs will be based upon the Company’s return on invested capital and its total return to shareholders over the vesting period relative to a peer group’s performance over the same period.

The Company measures and records financial instruments at fair value. A hierarchy is used for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of three levels:

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

Level 2 — Inputs other than Level 1 inputs that are either directly or indirectly observable; and

Level 3 — Unobservable inputs developed using estimates and assumptions developed by the Company, which reflect

those that a market participant would use.

The following table summarizes the financial instruments measured at fair value in the Consolidated Balance Sheets as of July 3, 2026 and December 31, 2025: 

(Thousands)						Total Carrying Value in the Consolidated Balance Sheets												Quoted Prices in  Active Markets  for Identical Assets (Level 1)												Significant Other Observable Inputs (Level 2)												Significant Unobservable Inputs (Level 3)

The Company uses a market approach to value the assets and liabilities for financial instruments in the table above. Outstanding contracts are valued through models that utilize market observable inputs, including both spot and forward prices, for the same underlying currencies, metals, and interest rates. The carrying values of the other working capital items and debt in the Consolidated Balance Sheets approximate fair values as of July 3, 2026 and December 31, 2025. The Company's deferred compensation investments and liabilities are based on the fair value of the investments corresponding to the employees’ investment selections, primarily in mutual funds, based on quoted prices in active markets for identical assets. Deferred compensation investments are primarily presented in Other assets. Deferred compensation liabilities are primarily presented in Other long-term liabilities.

The Company uses derivative contracts to hedge exposure to movements in interest rates associated with borrowings, foreign currency exposures, and precious metal and copper exposures. The objectives and strategies for using derivatives in these areas are as follows:

Interest Rate. On March 4, 2022, the Company entered into a $100.0 million interest rate swap to hedge the interest rate risk on the Credit Agreement described in Note Q. The swap hedges the change in 1-month Secured Overnight Financial Rate (SOFR) from March 4, 2022 to November 2, 2026. On March 21, 2023, the Company entered into two $50.0 million interest rate swaps to hedge the interest rate risk on the Credit Agreement. Additionally, on April 2, 2026 and June 11, 2026, the Company entered into forward starting interest rate swaps of $25.0 million and $15.0 million, respectively, to hedge the interest rate risk on the Credit Agreement. These swaps will hedge the change in 1-month SOFR from November 2, 2026 to June 25, 2030. The purpose of these hedges is to manage the risk of changes in the monthly interest payments attributable to changes in the benchmark interest rate.

Foreign Currency.    The Company sells a portion of its products to overseas customers in their local currencies, primarily the euro and yen. The Company secures foreign currency derivatives, mainly forward contracts and options, to hedge these anticipated sales transactions. The purpose of the hedge program is to protect against the reduction in the dollar value of foreign currency sales from adverse exchange rate movements. Should the dollar strengthen

---

significantly, the decrease in the translated value of the foreign currency sales should be partially offset by gains on the hedge contracts. Depending upon the methods used, the hedge contracts may limit the benefits from a weakening U.S. dollar.

The use of forward contracts locks in a firm rate and eliminates any downside from an adverse rate movement as well as any benefit from a favorable rate movement. The Company may from time to time choose to hedge with options or a tandem of options, known as a collar. These hedging techniques can limit or eliminate the downside risk but can allow for some or all of the benefit from a favorable rate movement to be realized. Unlike a forward contract, a premium is paid for an option; collars, which are a combination of a put and call option, may have a net premium but can be structured to be cash neutral. The Company will primarily hedge with forward contracts due to the relationship between the cash outlay and the level of risk.

The use of foreign currency derivative contracts is governed by policies approved by the Audit Committee of the Board of Directors. A team consisting of senior financial managers reviews the estimated exposure levels, as defined by budgets, forecasts, and other internal data, and determines the timing, amounts, and nature of instruments to use to hedge exposures. Management analyzes the effective hedged rates and the actual and projected gains and losses on the hedging transactions against the program objectives, targeted rates, and levels of risk assumed. Foreign currency contracts are typically layered in at different times for a specified exposure period in order to minimize the impact of market rate movements.

Precious Metals.    The Company maintains the majority of its precious metal production requirements on consignment in order to reduce its working capital investment and the exposure to metal price movements. When a product containing precious metal is fabricated and delivered to the customer, the metal content is purchased out of consignment based on the current market price. The price paid by the Company for the precious metal forms the basis for the price charged to the customer for the metal content in the product. This methodology allows for changes in either direction in the market prices of the precious metals used by the Company to be passed through to the customer and reduces the impact changes in prices could have on the Company's margins and operating profit. The consigned metal is owned by precious metal consignors that charge the Company consignment fees based upon the value of the metal as it fluctuates while on consignment. Each precious metal consignor retains title to its consigned precious metal until it is purchased by the Company, and it is the Company’s typical practice to purchase metal out of consignment only after a product containing that metal has been purchased by one of our customers.

In certain instances, a customer may want to fix the price for the precious metal at the time the sales order is placed rather than at the time of shipment. Setting the sales price at a different date than when the material would be purchased out of consignment potentially creates an exposure to movements in the market price of the metal. Therefore, in these limited situations, the Company may elect to enter into a forward contract to purchase precious metal. The forward contract allows the Company to purchase metal at a fixed price on a specific future date. The price in the forward contract serves as the basis for the price to be charged to the customer. By doing so, the selling price and purchase price are matched, and the Company's price exposure is reduced.

The Company refines precious metal-containing materials for its customers and typically will purchase the refined metal from the customer at current market prices. In limited circumstances, the customer may want to fix the price to be paid at the time of the order as opposed to when the material is refined. The customer may also want to fix the price for a set period of time. The Company may then elect to enter into a hedge contract, either a forward contract or a swap, to fix the price for the estimated quantity of metal to be refined and purchased, thereby reducing the exposure to adverse movements in the price of the metal. The Company may also enter into hedges to mitigate the risk relating to the prices of the metals that we process or refine.

In certain circumstances, the Company also refines metal from the customer and may retain a portion of the refined metal as payment. The Company may elect to enter into a forward contract to sell precious metal to reduce the Company's price exposure in these instances.

The Company may, from time to time, elect to purchase precious metal and hold in inventory rather than on consignment due to potential credit line limitations or other factors. These purchases are infrequent and, when made are typically held for a short duration. A forward contract will be secured at the time of the purchase to fix the price to

---

be paid when the metal is transferred back to the consignment line, thereby limiting any price exposure during the time when the metal was owned by the Company.

The Company will only enter into a derivative contract if there is an underlying identified exposure. Contracts are typically held to maturity. The Company does not engage in derivative trading activities and does not use derivatives for speculative purposes. The Company only uses hedge contracts that are denominated in the same currency or metal as the underlying exposure.

All derivatives are recorded on the balance sheet at fair value. If a derivative is designated and effective as a cash flow hedge, changes in the fair value of the derivative are recognized in other comprehensive income (OCI) and reclassified into income in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of a derivative's fair value, if any, is recognized in earnings immediately. If a derivative is not a hedge, changes in the fair value are adjusted through income. The fair values of the outstanding derivatives are recorded on the balance sheet as assets (if the derivatives are in a gain position) or liabilities (if the derivatives are in a loss position). The derivative assets and liabilities are classified as short-term or long-term depending upon the contract maturity date.

The following table summarizes the notional amount and the fair value of the Company’s outstanding derivatives not designated as hedging instruments (on a gross basis) and the balance sheet classification as of July 3, 2026 and December 31, 2025:

						July 3, 2026												December 31, 2025
(Thousands)						Notional Amount						Fair Value						Notional Amount						Fair Value

Other liabilities and accrued items						21,706						277						56,174						489

These outstanding foreign currency derivatives were related to balance sheet hedges and intercompany loans. Other-net included $0.6 million and $1.4 million of foreign currency gains in the second quarter and first six months of 2026, respectively, compared to $1.5 million and $2.0 million of foreign currency losses in the second quarter and first six months of 2025, respectively.

All of the contracts summarized above were designated and effective as cash flow hedges. We expect to reclassify $0.8 million of net gains into earnings in the next 12 months contemporaneously with the earnings effects of the related forecasted transactions. At July 3, 2026, the maximum term of derivative instruments that hedge forecasted transactions was approximately four years. Refer to Note L for further details related to OCI.

Legal Proceedings. The Company is party to several pending legal proceedings and claims arising in the normal course of business. The Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the event the Company determines that a loss is not probable, but is reasonably possible, and it becomes possible to develop what the Company believes to be a reasonable range of possible loss, then the Company will include disclosure related to such matters. To the extent there is a reasonable possibility that the losses could exceed any amounts accrued, the Company will adjust the accrual in the period the determination is made, disclose an estimate of the additional loss or range of loss, indicate that the estimate is immaterial with respect to its financial statements as a whole or, if the amount of such adjustment cannot be reasonably estimated, disclose that an estimate cannot be made.

On May 13, 2026, the Company received an adverse ruling from the Frankfurt am Main Regional Court in a matter involving Heraeus Metals Germany GmbH & Co. KG (“Heraeus”) related to the theft of 50 kilograms of gold granulate during transport in Germany in 2022. The Company has appealed the ruling. At the time of the incident, the gold was valued at approximately $2.5 million and is valued at approximately $6.7 million as of July 3, 2026, which will fluctuate in future periods as the potential exposure is dependent on future gold prices. The Company expects that approximately $2.5 million of any potential loss will be recoverable under its insurance coverage.

Based on management’s review of the ruling and underlying facts, consultation with legal counsel, and the Company’s appeal, management continues to believe that a loss is not probable at this time. Accordingly, no accrual was recorded at the time of the incident or as of the date of our financial statements. The Company will continue to monitor the appeal process and any changes in facts or circumstances that may affect its assessment.

Environmental Proceedings. The Company has an active environmental compliance program and records reserves for the probable cost of identified environmental remediation projects. The reserves are established based upon analyses conducted by the Company’s engineers and outside consultants and are adjusted from time to time based upon ongoing studies, the difference between actual and estimated costs, and other factors. The reserves may also be affected by rulings and negotiations with regulatory agencies. The undiscounted reserve balance was $2.4 million and $2.5 million at July 3, 2026 and December 31, 2025, respectively, and is included in Other liabilities and accrued items and Other long-term liabilities on the Consolidated Balance Sheet. Environmental projects tend to be long-term, and the final actual remediation costs may differ from the amounts currently recorded.

As of July 3, 2026 and December 31, 2025, the Company had $212.1 million outstanding at an average interest rate of 5.28% and $221.1 million outstanding at an average interest rate of 5.26%, respectively, under its revolving credit facility. The available borrowing capacity under the revolving credit facility as of July 3, 2026 was $232.7 million. The Company has the option to repay or borrow additional funds under the revolving credit facility until the maturity date in 2030.

In connection with the revolving credit facility, the administrative agent provides the Company with an overdraft sweep facility that the Company uses on a daily basis for short-term cash needs. As of July 3, 2026, there was $0.1 million outstanding on the overdraft sweep facility. The facility allows for an additional $30.0 million of liquidity. The amended and restated credit agreement governing the revolving credit facility and the term loan facility (Credit Agreement) includes covenants subject to a maximum leverage ratio and a minimum interest coverage ratio. We were in compliance with all of our debt covenants as of July 3, 2026.

Other sources of liquidity include uncommitted short-term lines of credit for certain of the Company's foreign subsidiaries, which currently provide for borrowings up to $22.4 million. At July 3, 2026 the Company had borrowings outstanding of $10.1 million which reduced the aggregate availability under these facilities to $12.3 million.

The balance outstanding on the term loan facility as of July 3, 2026 and December 31, 2025 was $219.4 million and $222.2 million, respectively.

At July 3, 2026 and December 31, 2025, there was $5.2 million outstanding against the letters of credit sub-facility.
