The Company's principal executive offices are located in Columbus, Ohio and Greifensee, Switzerland.

The accompanying interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and include all entities in which the Company has control, which are its wholly-owned subsidiaries. The interim consolidated financial statements have been prepared without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The interim consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

The accompanying interim consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2024.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. These financial statements were prepared using information reasonably available as of June 30, 2024 and through the date of this report. Actual results may differ from those estimates due to uncertainty around ongoing developments in Ukraine, the Israel-Hamas war, as well as other factors.

All intercompany transactions and balances have been eliminated.

Trade Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for expected credit losses represents the Company’s best estimate based on historical information, current information, and reasonable and supportable forecasts of future events and circumstances.

Inventories

Inventories are valued at the lower of cost or net realizable value. Cost, which includes direct materials, labor and overhead, is generally determined using the first in, first out (FIFO) method. The estimated net realizable value is based on assumptions for future demand and related pricing. Adjustments to the cost basis of the Company’s inventory are made for excess and obsolete items based on usage, orders and technological obsolescence. If actual market conditions are less favorable than those projected by management, reductions in the value of inventory may be required.

Inventories consisted of the following:

			June 30, 2024						December 31, 2023
Raw materials and parts			$	171,135					$	180,352
Work-in-progress			72,982						81,181
Finished goods			122,278						124,332
			$	366,395					$	385,865

Goodwill and Other Intangible Assets

Goodwill, representing the excess of purchase price over the net asset value of companies acquired, and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The annual evaluation for goodwill and indefinite-lived intangible assets are generally based on an assessment of qualitative factors to determine whether it is more likely than not that the fair value of the assets are less than its carrying amount.

Other intangible assets include indefinite-lived assets and assets subject to amortization. Where applicable, amortization is charged on a straight-line basis over the expected period of benefit. The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company assesses the initial acquisition of intangible assets in accordance with the provisions of ASC 805 "Business Combinations" and the continued accounting for previously recognized intangible assets and goodwill in accordance with the provisions of ASC 350 "Intangible - Goodwill and Other" and ASC 360 "Property, Plant and Equipment".

Other intangible assets consisted of the following:

			June 30, 2024																		December 31, 2023
			Gross Amount						Accumulated Amortization						Intangibles, Net						Gross Amount						Accumulated Amortization						Intangibles, Net

The Company recognized amortization expense associated with the above intangible assets of $6.7 million and $6.9 million for the three months ended June 30, 2024 and 2023, respectively, and $13.6 million and $13.8 million for the six months ended June 30, 2024 and 2023, respectively. The annual aggregate amortization expense based on the current balance of other intangible assets is estimated to be $27.2 million for 2024, $26.2 million for 2025, $22.2 million for 2026, $20.7 million for 2027, $19.4 million for 2028, and $17.7 million for 2029. Purchased intangible amortization was $6.5 million, $5.0 million after tax, and $6.7 million, $5.2 million after tax, for the three months ended June 30, 2024 and 2023, respectively, and $13.1 million, $10.1 million after tax, and $13.3 million, $10.3 million after tax, for the six months ended June 30, 2024 and 2023, respectively.

In addition to the above amortization, the Company recorded amortization expense associated with capitalized software of $11.4 million and $11.1 million for the three months ended June 30, 2024 and 2023, respectively, and $22.7 million and $22.0 million for the six months ended June 30, 2024 and 2023, respectively.

Revenue Recognition

Product revenue is recognized from contracts with customers when a customer has obtained control of a product. The Company considers control to have transferred based upon shipping terms. To the extent the Company’s arrangements have a separate performance obligation, revenue related to any post-shipment performance obligation is deferred until completed. Shipping and handling costs charged to customers are included in total net sales and the associated expense is a component of cost of sales. Certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the end customer. Revenue is recognized on these distributor arrangements upon transfer of control to the distributor. Contracts do not contain variable pricing arrangements that are retrospective, except for rebate programs. Rebates are estimated based on expected sales volumes and offset against revenue at the time such revenue is recognized. The Company generally maintains the right to accept or reject a product return in its terms and conditions and also maintains appropriate accruals for outstanding credits. The related provisions for estimated returns and rebates are immaterial to the consolidated financial statements.

Certain of the Company’s product arrangements include separate performance obligations, primarily related to installation. Such performance obligations are accounted for separately when the deliverables have stand-alone value and the satisfaction of the undelivered performance obligations is probable and within the Company's control. The allocation of revenue between the performance obligations is based on the observable stand-alone selling prices at the time of the sale in accordance with a number of factors including service technician billing rates, time to install, and geographic location.

Software is generally not considered a distinct performance obligation with the exception of a few small software applications. The Company generally does not sell software products without the related hardware instrument as the software is embedded in the product. The Company’s products typically require no significant production, modification, or customization of the hardware or software that is essential to the functionality of the products.

Service revenue not under contract is recognized upon the completion of the service performed. Revenue from spare parts sold on a stand-alone basis is recognized when control is transferred to the customer, which is generally at the time of shipment or delivery. Revenue from service contracts is recognized ratably over the contract period using a time-based method. These contracts represent an obligation to perform repair and other services including regulatory compliance qualification, calibration, certification, and preventative maintenance on a customer’s pre-defined equipment over the contract period.

Share-Based Compensation

The Company recognizes share-based compensation expense within selling, general and administrative in the consolidated statements of operations and other comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $4.5 million and $9.3 million of share-based compensation expense for the three and six months ended June 30, 2024, respectively, compared to $4.2 million and $8.2 million for the corresponding periods in 2023.

Research and Development

Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred.

Business Combinations and Asset Acquisitions

The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in the Company's consolidated results as of the acquisition date. The purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values and any consideration in excess of the net assets acquired is recognized as goodwill. The determination of the values of the acquired assets and assumed liabilities, including goodwill and intangible assets, require significant judgment. Acquisition transaction costs are expensed when incurred.

In circumstances where an acquisition involves a contingent consideration arrangement, the Company recognizes a liability equal to the fair value of the expected contingent payments as of the acquisition date. Subsequent changes in the fair value of the contingent consideration are recorded to other charges (income), net.

Recent Accounting Pronouncements

In March 2020, January 2021 and December 2022, the FASB issued ASU 2020-04, ASU 2021-01 and ASU 2022-06: Reference Rate Reform, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuance of LIBOR or another referenced rate. The guidance may be applied to any applicable contract entered into before December 31, 2024. The Company amended its credit agreement and cross currency swap agreements in June 2023 to change the interest rate benchmark from LIBOR to SOFR and other non-U.S. dollar references, which did not change the amount or timing of cash flows. As a result, the discontinuation of LIBOR did not have a material impact on the Company's financial statements.

In November 2023, the FASB issued ASU 2023-07: Improvements to Reportable Segment Disclosures which requires incremental disclosures about a public entity's reportable segments but does not change the definition of a segment or the guidance for determining reportable segments. The Company will adopt the annual disclosure requirements in 2024 and is currently evaluating the impact of these requirements on the consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09: Improvements to Income Tax Disclosures, which enhances income tax disclosures, especially related to the rate reconciliation and income taxes paid information. The Company will adopt the annual disclosure requirements in 2025 and is currently evaluating the impact of these requirements on the consolidated financial statements.

The Company disaggregates revenue from contracts with customers by product, service, timing of revenue recognition and geography. A summary of revenue by the Company’s reportable segments for the three and six months ended June 30, 2024 and 2023 follows:

For the three months ended June 30, 2024			U.S. Operations						Swiss Operations						Western European Operations						Chinese Operations						Other Operations						Total

The Company's global revenue mix by product category is laboratory (56% of sales), industrial (39% of sales) and retail (5% of sales). The Company's product revenue by reportable segment is proportionately similar to the Company's global mix except the Company's Swiss Operations is largely comprised of laboratory products while the Company's Chinese Operations has a slightly higher percentage of industrial products. A breakdown of the Company’s sales by product category for the three and six months ended June 30 is as follows:

			Three Months Ended												Six Months Ended
			2024						2023						2024						2023
Laboratory			$	523,233					$	526,699					$	1,048,288					$	1,046,730
Industrial			374,257						399,001						726,102						754,181
Retail			49,260						56,417						98,309						109,944
Total			$	946,750					$	982,117					$	1,872,699					$	1,910,855

The payment terms in the Company’s contracts with customers do not exceed one year and therefore contracts do not contain a significant financing component. In most cases, after appropriate credit evaluations, payments are due in arrears and are recognized as receivables. Unbilled revenue is recorded when performance obligations have been satisfied, but not yet billed to the customer. Unbilled revenue as of June 30, 2024 and December 31, 2023 was $39.4 million and $35.7 million, respectively, and is included within accounts receivable. Deferred revenue and customer prepayments are recorded when cash payments are received or due in advance of the performance obligation being satisfied. Deferred revenue primarily includes prepaid service contracts, as well as deferred installation.

Changes in the components of deferred revenue and customer prepayments during the six month periods ending June 30, 2024 and 2023 are as follows:

						2024						2023
Beginning balances as of January 1						$	202,022					$	192,759
Customer pre-payments/deferred revenue						338,581						343,373
Revenue recognized						(320,727)						(332,005)
Foreign currency translation						(5,671)						422
Ending balance as of June 30						$	214,205					$	204,549

The Company generally expenses sales commissions when incurred because the contract period is one year or less. These costs are recorded within selling, general, and administrative expenses. The value of unsatisfied performance obligations other than customer prepayments and deferred revenue associated with contracts greater than one year is immaterial.

At June 30, 2024 and December 31, 2023, the Company had derivative assets totaling $3.4 million and $8.3 million respectively, and derivative liabilities totaling $5.7 million and $25.2 million, respectively. The Company has limited involvement with derivative financial instruments and therefore does not present all the required disclosures in tabular format. The fair values of the cross-currency swap agreements and foreign currency forward contracts that economically hedge short-term intercompany balances are estimated based upon inputs from current valuation information obtained from dealer quotes and priced with observable market assumptions and appropriate valuation adjustments for credit risk. The Company has evaluated the valuation methodologies used to develop the fair values by dealers in order to determine whether such valuations are representative of an exit price in the Company’s principal market. In addition, the Company uses an internally developed model to perform testing on the valuations received from brokers. The Company has also considered both its own credit risk and counterparty credit risk in determining fair value and determined these adjustments were insignificant at June 30, 2024 and December 31, 2023.

Under U.S. GAAP, 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. A fair value measurement consists of observable and unobservable inputs that reflect the assumptions that a market participant would use in pricing an asset or liability.

A fair value hierarchy has been established that categorizes these inputs into three levels:

Level 1:    Quoted prices in active markets for identical assets and liabilities

Level 2:    Observable inputs other than quoted prices in active markets for identical assets and liabilities

Level 3:    Unobservable inputs

---

The following table presents the Company's assets and liabilities, which are all categorized as Level 2, that are measured at fair value on a recurring basis. The Company does not have any assets or liabilities which are categorized as Level 1:

						June 30, 2024						December 31, 2023						Balance Sheet Classification
Foreign currency forward contracts not designated as hedging instruments						$	1,961					$	8,330					Other current assets and prepaid expenses
Cash Flow Hedges:
Cross currency swap agreement						864						—						Other current assets and prepaid expenses
Cross currency swap agreement						544						—						Other non-current assets
Total derivative assets						$	3,369					$	8,330
Foreign currency forward contracts not designated as hedging instruments						$	1,897					$	8,245					Accrued and other liabilities
Cash Flow Hedges:
Cross currency swap agreement						—						2,678						Accrued and other liabilities
Cross currency swap agreement						3,829						14,270						Other non-current liabilities
Total derivative liabilities						$	5,726					$	25,193

The Company had $6.7 million and $4.0 million of cash equivalents at June 30, 2024 and December 31, 2023, respectively, the fair value of which is determined using Level 2 inputs, through quoted and corroborated prices in active markets. The fair value of cash equivalents approximates cost.

The fair value of the Company's debt is less than the carrying value by approximately $209.2 million as of June 30, 2024. The fair value of the Company's fixed interest rate debt was estimated using Level 2 inputs, primarily discounted cash flow models, based on estimated current rates offered for similar debt under current market conditions for the Company.

Total long-term debt			$	1,084,854					$	661,784					$	1,746,638

(a) The benchmark interest rate is determined by the borrowing currency. The benchmark rates by borrowing currency are as follows: SOFR for U.S. dollars (plus a 10 basis points spread adjustment), SARON for Swiss franc, EURIBOR for Euro and SONIA for Great British pounds.

On May 30, 2024, the Company entered into a $1.35 billion Credit Agreement (the Credit Agreement), which amended its $1.25 billion Amended and Restated Credit Agreement (the Prior Credit Agreement). As of June 30, 2024, the Company had $712.0 million of additional borrowings available under its Credit Agreement, and the Company maintained $70.8 million of cash and cash equivalents.

The Credit Agreement is provided by a group of financial institutions (similar to the Company's Prior Credit Agreement) and has a maturity date of 2029. It is a revolving credit facility and is not subject to any scheduled principal payments prior to maturity. The obligations under the Credit Agreement are unsecured.

Borrowings under the Credit Agreement bear interest at current market rates plus a margin based on the Company’s consolidated leverage ratio. The Company must also pay facility fees that are tied to its leverage ratio. The Credit Agreement contains covenants that are similar to those contained in the prior Credit Agreement, with which the Company was in compliance as of June 30, 2024.

The Company is required to maintain (i) a ratio of net funded indebtedness to EBITDA of 3.5 to 1.0 or less, except in certain circumstances and (ii) an interest coverage ratio of 3.0 to 1.0 or greater. The Credit Agreement also places certain limitations on the Company, including limiting the ability to incur liens or indebtedness at a subsidiary level. In addition, the Credit Agreement has several events of default,

with customary grace periods applicable. The Company incurred approximately $0.2 million of debt extinguishment costs during 2024 related to the Prior Credit Agreement. The Company capitalized $2.0 million in financing fees during 2024 associated with the Credit Agreement which will be amortized to interest expense through 2029.

In May 2023, the Company amended its Prior Credit Agreement to replace all references of LIBOR to SOFR and other non-U.S. dollar references as the interest rate benchmark.

In December 2022, the Company entered into an agreement to issue and sell $150 million 10-year Senior Notes in a private placement. The Company issued $150 million with a fixed interest rate of 5.45% (5.45% Senior Notes) in March 2023. The 5.45% Senior Notes are senior unsecured obligations of the Company. The 5.45% Senior Notes mature in March 2033. The terms of the 5.45% Senior Notes are consistent with the previous Senior Notes as described in the Company's Annual Report on Form 10-K. The Company used the proceeds from the sale of the 5.45% Senior Notes to refinance existing indebtedness and for other general corporate purposes.

The Company has designated the EUR 125 million 1.47% Euro Senior Notes, the EUR 135 million 1.30% Euro Senior Notes, and the EUR 125 million 1.06% Euro Senior Notes as a hedge of a portion of its net investment in euro-denominated foreign subsidiaries to reduce foreign currency risk associated with the net investment. Changes in the carrying value of this debt resulting from fluctuations in the euro to U.S. dollar exchange rate are recorded as foreign currency translation adjustments within other comprehensive income (loss). The Company recorded in other comprehensive income (loss) related to this net investment hedge an unrealized gain of $5.1 million and unrealized loss of $3.6 million for the three months ended June 30, 2024 and 2023, respectively, and an unrealized gain of $13.3 million and unrealized loss of $8.9 million for the six month periods ended June 30, 2024 and 2023, respectively. The Company has an unrealized gain of $30.6 million recorded in accumulated other comprehensive income (loss) as of June 30, 2024.

Other Local Arrangements

The Company has $2.1 billion of remaining availability for its share repurchase program as of June 30, 2024. The share repurchases are expected to be funded from cash generated from operating activities, borrowings, and cash balances. Repurchases will be made through open market transactions, and the amount and timing of purchases will depend on business and market conditions, the stock price, trading restrictions, the level of acquisition activity, and other factors.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Mettler-Toledo International Inc. (Mettler-Toledo or the Company) is a leading global supplier of precision instruments and services. The Company manufactures weighing instruments for use in laboratory, industrial, packaging, logistics and food retailing applications. The Company also manufactures several related analytical instruments and provides automated chemistry solutions used in drug and chemical compound discovery and development. In addition, the Company manufactures metal detection and other end-of-line inspection systems used in production and packaging and provides solutions for use in certain process analytics applications. The Company's primary manufacturing facilities are located in China, Germany, Switzerland, the United Kingdom, the United States and Mexico. The Company's principal executive offices are located in Columbus, Ohio and Greifensee, Switzerland. The accompanying interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and include all entities in which the Company has control, which are its wholly-owned subsidiaries. The interim consolidated financial statements have been prepared without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The interim consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. The accompanying interim consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2024. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. These financial statements were prepared using information reasonably available as of June 30, 2024 and through the date of this report. Actual results may differ from those estimates due to uncertainty around ongoing developments in Ukraine, the Israel-Hamas war, as well as other factors. All intercompany transactions and balances have been eliminated.

Summary of Significant Accounting Policies	6 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for expected credit losses represents the Company’s best estimate based on historical information, current information, and reasonable and supportable forecasts of future events and circumstances. Inventories Inventories are valued at the lower of cost or net realizable value. Cost, which includes direct materials, labor and overhead, is generally determined using the first in, first out (FIFO) method. The estimated net realizable value is based on assumptions for future demand and related pricing. Adjustments to the cost basis of the Company’s inventory are made for excess and obsolete items based on usage, orders and technological obsolescence. If actual market conditions are less favorable than those projected by management, reductions in the value of inventory may be required. Inventories consisted of the following: June 30, 2024 December 31, 2023 Raw materials and parts $ 171,135  $ 180,352  Work-in-progress 72,982  81,181  Finished goods 122,278  124,332    $ 366,395  $ 385,865  Goodwill and Other Intangible Assets Goodwill, representing the excess of purchase price over the net asset value of companies acquired, and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The annual evaluation for goodwill and indefinite-lived intangible assets are generally based on an assessment of qualitative factors to determine whether it is more likely than not that the fair value of the assets are less than its carrying amount. Other intangible assets include indefinite-lived assets and assets subject to amortization. Where applicable, amortization is charged on a straight-line basis over the expected period of benefit. The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company assesses the initial acquisition of intangible assets in accordance with the provisions of ASC 805 "Business Combinations" and the continued accounting for previously recognized intangible assets and goodwill in accordance with the provisions of ASC 350 "Intangible - Goodwill and Other" and ASC 360 "Property, Plant and Equipment". Other intangible assets consisted of the following:   June 30, 2024 December 31, 2023 Gross Amount Accumulated Amortization Intangibles, Net Gross Amount Accumulated Amortization Intangibles, Net Customer relationships $ 286,191  $ (109,880) $ 176,311  $ 294,180  $ (107,665) $ 186,515  Proven technology and patents 126,154  (76,770) 49,384  129,227  (75,014) 54,213  Tradenames (finite life) 7,762  (4,869) 2,893  7,908  (4,535) 3,373  Tradenames (indefinite life) 35,104  —  35,104  36,320  —  36,320  Other 12,411  (7,949) 4,462  13,236  (8,228) 5,008    $ 467,622  $ (199,468) $ 268,154  $ 480,871  $ (195,442) $ 285,429  The Company recognized amortization expense associated with the above intangible assets of $6.7 million and $6.9 million for the three months ended June 30, 2024 and 2023, respectively, and $13.6 million and $13.8 million for the six months ended June 30, 2024 and 2023, respectively. The annual aggregate amortization expense based on the current balance of other intangible assets is estimated to be $27.2 million for 2024, $26.2 million for 2025, $22.2 million for 2026, $20.7 million for 2027, $19.4 million for 2028, and $17.7 million for 2029. Purchased intangible amortization was $6.5 million, $5.0 million after tax, and $6.7 million, $5.2 million after tax, for the three months ended June 30, 2024 and 2023, respectively, and $13.1 million, $10.1 million after tax, and $13.3 million, $10.3 million after tax, for the six months ended June 30, 2024 and 2023, respectively. In addition to the above amortization, the Company recorded amortization expense associated with capitalized software of $11.4 million and $11.1 million for the three months ended June 30, 2024 and 2023, respectively, and $22.7 million and $22.0 million for the six months ended June 30, 2024 and 2023, respectively. Revenue Recognition Product revenue is recognized from contracts with customers when a customer has obtained control of a product. The Company considers control to have transferred based upon shipping terms. To the extent the Company’s arrangements have a separate performance obligation, revenue related to any post-shipment performance obligation is deferred until completed. Shipping and handling costs charged to customers are included in total net sales and the associated expense is a component of cost of sales. Certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the end customer. Revenue is recognized on these distributor arrangements upon transfer of control to the distributor. Contracts do not contain variable pricing arrangements that are retrospective, except for rebate programs. Rebates are estimated based on expected sales volumes and offset against revenue at the time such revenue is recognized. The Company generally maintains the right to accept or reject a product return in its terms and conditions and also maintains appropriate accruals for outstanding credits. The related provisions for estimated returns and rebates are immaterial to the consolidated financial statements. Certain of the Company’s product arrangements include separate performance obligations, primarily related to installation. Such performance obligations are accounted for separately when the deliverables have stand-alone value and the satisfaction of the undelivered performance obligations is probable and within the Company's control. The allocation of revenue between the performance obligations is based on the observable stand-alone selling prices at the time of the sale in accordance with a number of factors including service technician billing rates, time to install, and geographic location. Software is generally not considered a distinct performance obligation with the exception of a few small software applications. The Company generally does not sell software products without the related hardware instrument as the software is embedded in the product. The Company’s products typically require no significant production, modification, or customization of the hardware or software that is essential to the functionality of the products. Service revenue not under contract is recognized upon the completion of the service performed. Revenue from spare parts sold on a stand-alone basis is recognized when control is transferred to the customer, which is generally at the time of shipment or delivery. Revenue from service contracts is recognized ratably over the contract period using a time-based method. These contracts represent an obligation to perform repair and other services including regulatory compliance qualification, calibration, certification, and preventative maintenance on a customer’s pre-defined equipment over the contract period. Share-Based Compensation The Company recognizes share-based compensation expense within selling, general and administrative in the consolidated statements of operations and other comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $4.5 million and $9.3 million of share-based compensation expense for the three and six months ended June 30, 2024, respectively, compared to $4.2 million and $8.2 million for the corresponding periods in 2023. Research and Development Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred. Business Combinations and Asset Acquisitions The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in the Company's consolidated results as of the acquisition date. The purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values and any consideration in excess of the net assets acquired is recognized as goodwill. The determination of the values of the acquired assets and assumed liabilities, including goodwill and intangible assets, require significant judgment. Acquisition transaction costs are expensed when incurred. In circumstances where an acquisition involves a contingent consideration arrangement, the Company recognizes a liability equal to the fair value of the expected contingent payments as of the acquisition date. Subsequent changes in the fair value of the contingent consideration are recorded to other charges (income), net. Recent Accounting Pronouncements In March 2020, January 2021 and December 2022, the FASB issued ASU 2020-04, ASU 2021-01 and ASU 2022-06: Reference Rate Reform, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuance of LIBOR or another referenced rate. The guidance may be applied to any applicable contract entered into before December 31, 2024. The Company amended its credit agreement and cross currency swap agreements in June 2023 to change the interest rate benchmark from LIBOR to SOFR and other non-U.S. dollar references, which did not change the amount or timing of cash flows. As a result, the discontinuation of LIBOR did not have a material impact on the Company's financial statements. In November 2023, the FASB issued ASU 2023-07: Improvements to Reportable Segment Disclosures which requires incremental disclosures about a public entity's reportable segments but does not change the definition of a segment or the guidance for determining reportable segments. The Company will adopt the annual disclosure requirements in 2024 and is currently evaluating the impact of these requirements on the consolidated financial statements. In December 2023, the FASB issued ASU 2023-09: Improvements to Income Tax Disclosures, which enhances income tax disclosures, especially related to the rate reconciliation and income taxes paid information. The Company will adopt the annual disclosure requirements in 2025 and is currently evaluating the impact of these requirements on the consolidated financial statements.

Revenue from Contract with Customer [Text Block]	REVENUE The Company disaggregates revenue from contracts with customers by product, service, timing of revenue recognition and geography. A summary of revenue by the Company’s reportable segments for the three and six months ended June 30, 2024 and 2023 follows: For the three months ended June 30, 2024 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 264,345  $ 39,418  $ 137,113  $ 148,436  $ 122,948  $ 712,260  Service Revenue: Point in time 73,839  7,615  43,218  11,753  34,614  171,039  Over time 24,031  3,152  21,982  4,195  10,091  63,451  Total $ 362,215  $ 50,185  $ 202,313  $ 164,384  $ 167,653  $ 946,750  For the three months ended June 30, 2023 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 265,881  $ 36,662  $ 130,404  $ 204,259  $ 121,765  $ 758,971  Service Revenue: Point in time 72,250  7,246  40,831  13,020  32,142  165,489  Over time 20,984  2,895  20,840  4,390  8,548  57,657  Total $ 359,115  $ 46,803  $ 192,075  $ 221,669  $ 162,455  $ 982,117  For the six months ended June 30, 2024 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 515,081  $ 83,039  $ 288,648  $ 277,447  $ 249,013  $ 1,413,228  Service Revenue: Point in time 146,973  15,379  86,039  21,654  65,824  335,869  Over time 46,284  6,017  42,391  8,481  20,429  123,602  Total $ 708,338  $ 104,435  $ 417,078  $ 307,582  $ 335,266  $ 1,872,699  For the six months ended June 30, 2023 U.S. Operations Swiss Operations Western European Operations Chinese Operations Other Operations Total Product Revenue $ 512,410  $ 73,123  $ 271,111  $ 374,689  $ 243,639  $ 1,474,972  Service Revenue: Point in time 142,875  14,707  81,996  24,368  62,187  326,133  Over time 41,231  5,342  38,392  8,380  16,405  109,750  Total $ 696,516  $ 93,172  $ 391,499  $ 407,437  $ 322,231  $ 1,910,855  A breakdown of net sales to external customers by geographic customer destination for the three and six months ended June 30 follows: Three Months Ended Six Months Ended 2024 2023 2024 2023 Americas $ 404,030  $ 396,897  $ 788,373  $ 768,970  Europe 258,836  246,340  532,697  500,314  Asia / Rest of World 283,884  338,880  551,629  641,571  Total $ 946,750  $ 982,117  $ 1,872,699  $ 1,910,855  The Company's global revenue mix by product category is laboratory (56% of sales), industrial (39% of sales) and retail (5% of sales). The Company's product revenue by reportable segment is proportionately similar to the Company's global mix except the Company's Swiss Operations is largely comprised of laboratory products while the Company's Chinese Operations has a slightly higher percentage of industrial products. A breakdown of the Company’s sales by product category for the three and six months ended June 30 is as follows: Three Months Ended Six Months Ended 2024 2023 2024 2023 Laboratory $ 523,233  $ 526,699  $ 1,048,288  $ 1,046,730  Industrial 374,257  399,001  726,102  754,181  Retail 49,260  56,417  98,309  109,944  Total $ 946,750  $ 982,117  $ 1,872,699  $ 1,910,855  The payment terms in the Company’s contracts with customers do not exceed one year and therefore contracts do not contain a significant financing component. In most cases, after appropriate credit evaluations, payments are due in arrears and are recognized as receivables. Unbilled revenue is recorded when performance obligations have been satisfied, but not yet billed to the customer. Unbilled revenue as of June 30, 2024 and December 31, 2023 was $39.4 million and $35.7 million, respectively, and is included within accounts receivable. Deferred revenue and customer prepayments are recorded when cash payments are received or due in advance of the performance obligation being satisfied. Deferred revenue primarily includes prepaid service contracts, as well as deferred installation. Changes in the components of deferred revenue and customer prepayments during the six month periods ending June 30, 2024 and 2023 are as follows: 2024 2023 Beginning balances as of January 1 $ 202,022  $ 192,759  Customer pre-payments/deferred revenue 338,581  343,373  Revenue recognized (320,727) (332,005) Foreign currency translation (5,671) 422  Ending balance as of June 30 $ 214,205  $ 204,549  The Company generally expenses sales commissions when incurred because the contract period is one year or less. These costs are recorded within selling, general, and administrative expenses. The value of unsatisfied performance obligations other than customer prepayments and deferred revenue associated with contracts greater than one year is immaterial.

Fair Value Measurements	6 Months Ended
	Jun. 30, 2024
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS At June 30, 2024 and December 31, 2023, the Company had derivative assets totaling $3.4 million and $8.3 million respectively, and derivative liabilities totaling $5.7 million and $25.2 million, respectively. The Company has limited involvement with derivative financial instruments and therefore does not present all the required disclosures in tabular format. The fair values of the cross-currency swap agreements and foreign currency forward contracts that economically hedge short-term intercompany balances are estimated based upon inputs from current valuation information obtained from dealer quotes and priced with observable market assumptions and appropriate valuation adjustments for credit risk. The Company has evaluated the valuation methodologies used to develop the fair values by dealers in order to determine whether such valuations are representative of an exit price in the Company’s principal market. In addition, the Company uses an internally developed model to perform testing on the valuations received from brokers. The Company has also considered both its own credit risk and counterparty credit risk in determining fair value and determined these adjustments were insignificant at June 30, 2024 and December 31, 2023. Under U.S. GAAP, 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. A fair value measurement consists of observable and unobservable inputs that reflect the assumptions that a market participant would use in pricing an asset or liability. A fair value hierarchy has been established that categorizes these inputs into three levels: Level 1:    Quoted prices in active markets for identical assets and liabilities Level 2:    Observable inputs other than quoted prices in active markets for identical assets and liabilities Level 3:    Unobservable inputs The following table presents the Company's assets and liabilities, which are all categorized as Level 2, that are measured at fair value on a recurring basis. The Company does not have any assets or liabilities which are categorized as Level 1:   June 30, 2024 December 31, 2023 Balance Sheet Classification Foreign currency forward contracts not designated as hedging instruments $ 1,961  $ 8,330  Other current assets and prepaid expenses Cash Flow Hedges: Cross currency swap agreement 864 —  Other current assets and prepaid expenses Cross currency swap agreement 544 —  Other non-current assets Total derivative assets $ 3,369  $ 8,330  Foreign currency forward contracts not designated as hedging instruments $ 1,897  $ 8,245  Accrued and other liabilities Cash Flow Hedges: Cross currency swap agreement —  2,678  Accrued and other liabilities Cross currency swap agreement 3,829  14,270  Other non-current liabilities Total derivative liabilities $ 5,726  $ 25,193  The Company had $6.7 million and $4.0 million of cash equivalents at June 30, 2024 and December 31, 2023, respectively, the fair value of which is determined using Level 2 inputs, through quoted and corroborated prices in active markets. The fair value of cash equivalents approximates cost. The fair value of the Company's debt is less than the carrying value by approximately $209.2 million as of June 30, 2024. The fair value of the Company's fixed interest rate debt was estimated using Level 2 inputs, primarily discounted cash flow models, based on estimated current rates offered for similar debt under current market conditions for the Company.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESThe Company's reported tax rate was 8.8% and 18.8% during the three months ended June 30, 2024 and 2023, respectively and 13.9% and 17.9% during the six months ended June 30, 2024 and 2023, respectively. The provision for taxes is based upon using the Company's projected annual effective tax rate of 19.0% before non-recurring discrete tax items during 2024 and 2023. The difference between the Company's projected annual effective tax rate and the reported tax rate is primarily related to the timing of excess tax benefits associated with stock option exercises. The reported tax rate for the three and six month periods ended June 30, 2024 also includes a non-cash discrete tax benefit of $23.0 million resulting from the reduction of uncertain tax position liabilities related to the settlement of a tax audit

The benchmark rates by borrowing currency are as follows: SOFR for U.S. dollars (plus a 10 basis points spread adjustment), SARON for Swiss franc, EURIBOR for Euro and SONIA for Great British pounds. On May 30, 2024, the Company entered into a $1.35 billion Credit Agreement (the Credit Agreement), which amended its $1.25 billion Amended and Restated Credit Agreement (the Prior Credit Agreement). As of June 30, 2024, the Company had $712.0 million of additional borrowings available under its Credit Agreement, and the Company maintained $70.8 million of cash and cash equivalents. The Credit Agreement is provided by a group of financial institutions (similar to the Company's Prior Credit Agreement) and has a maturity date of 2029. It is a revolving credit facility and is not subject to any scheduled principal payments prior to maturity. The obligations under the Credit Agreement are unsecured. Borrowings under the Credit Agreement bear interest at current market rates plus a margin based on the Company’s consolidated leverage ratio. The Company must also pay facility fees that are tied to its leverage ratio. The Credit Agreement contains covenants that are similar to those contained in the prior Credit Agreement, with which the Company was in compliance as of June 30, 2024. The Company is required to maintain (i) a ratio of net funded indebtedness to EBITDA of 3.5 to 1.0 or less, except in certain circumstances and (ii) an interest coverage ratio of 3.0 to 1.0 or greater. The Credit Agreement also places certain limitations on the Company, including limiting the ability to incur liens or indebtedness at a subsidiary level. In addition, the Credit Agreement has several events of default, with customary grace periods applicable. The Company incurred approximately $0.2 million of debt extinguishment costs during 2024 related to the Prior Credit Agreement. The Company capitalized $2.0 million in financing fees during 2024 associated with the Credit Agreement which will be amortized to interest expense through 2029. In May 2023, the Company amended its Prior Credit Agreement to replace all references of LIBOR to SOFR and other non-U.S. dollar references as the interest rate benchmark. In December 2022, the Company entered into an agreement to issue and sell $150 million 10-year Senior Notes in a private placement. The Company issued $150 million with a fixed interest rate of 5.45% (5.45% Senior Notes) in March 2023. The 5.45% Senior Notes are senior unsecured obligations of the Company. The 5.45% Senior Notes mature in March 2033. The terms of the 5.45% Senior Notes are consistent with the previous Senior Notes as described in the Company's Annual Report on Form 10-K. The Company used the proceeds from the sale of the 5.45% Senior Notes to refinance existing indebtedness and for other general corporate purposes. The Company has designated the EUR 125 million 1.47% Euro Senior Notes, the EUR 135 million 1.30% Euro Senior Notes, and the EUR 125 million 1.06% Euro Senior Notes as a hedge of a portion of its net investment in euro-denominated foreign subsidiaries to reduce foreign currency risk associated with the net investment. Changes in the carrying value of this debt resulting from fluctuations in the euro to U.S. dollar exchange rate are recorded as foreign currency translation adjustments within other comprehensive income (loss). The Company recorded in other comprehensive income (loss) related to this net investment hedge an unrealized gain of $5.1 million and unrealized loss of $3.6 million for the three months ended June 30, 2024 and 2023, respectively, and an unrealized gain of $13.3 million and unrealized loss of $8.9 million for the six month periods ended June 30, 2024 and 2023, respectively. The Company has an unrealized gain of $30.6 million recorded in accumulated other comprehensive income (loss) as of June 30, 2024. Other Local Arrangements In April 2018, two of the Company's non-U.S. pension plans issued loans totaling $39.6 million (Swiss franc 38 million) to a wholly owned subsidiary of the Company. The loans have the same terms and conditions, which include an interest rate of SARON plus 87.5 basis points. The loans were renewed for one year in April 2024.

Accounting Policies [Abstract]
Trade Accounts Receivable	Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for expected credit losses represents the Company’s best estimate based on historical information, current information, and reasonable and supportable forecasts of future events and circumstances.
Inventories	Inventories Inventories are valued at the lower of cost or net realizable value. Cost, which includes direct materials, labor and overhead, is generally determined using the first in, first out (FIFO) method. The estimated net realizable value is based on assumptions for future demand and related pricing. Adjustments to the cost basis of the Company’s inventory are made for excess and obsolete items based on usage, orders and technological obsolescence. If actual market conditions are less favorable than those projected by management, reductions in the value of inventory may be required. Inventories consisted of the following: June 30, 2024 December 31, 2023 Raw materials and parts $ 171,135  $ 180,352  Work-in-progress 72,982  81,181  Finished goods 122,278  124,332    $ 366,395  $ 385,865
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill, representing the excess of purchase price over the net asset value of companies acquired, and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The annual evaluation for goodwill and indefinite-lived intangible assets are generally based on an assessment of qualitative factors to determine whether it is more likely than not that the fair value of the assets are less than its carrying amount. Other intangible assets include indefinite-lived assets and assets subject to amortization. Where applicable, amortization is charged on a straight-line basis over the expected period of benefit. The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company assesses the initial acquisition of intangible assets in accordance with the provisions of ASC 805 "Business Combinations" and the continued accounting for previously recognized intangible assets and goodwill in accordance with the provisions of ASC 350 "Intangible - Goodwill and Other" and ASC 360 "Property, Plant and Equipment". Other intangible assets consisted of the following:   June 30, 2024 December 31, 2023 Gross Amount Accumulated Amortization Intangibles, Net Gross Amount Accumulated Amortization Intangibles, Net Customer relationships $ 286,191  $ (109,880) $ 176,311  $ 294,180  $ (107,665) $ 186,515  Proven technology and patents 126,154  (76,770) 49,384  129,227  (75,014) 54,213  Tradenames (finite life) 7,762  (4,869) 2,893  7,908  (4,535) 3,373  Tradenames (indefinite life) 35,104  —  35,104  36,320  —  36,320  Other 12,411  (7,949) 4,462  13,236  (8,228) 5,008    $ 467,622  $ (199,468) $ 268,154  $ 480,871  $ (195,442) $ 285,429  The Company recognized amortization expense associated with the above intangible assets of $6.7 million and $6.9 million for the three months ended June 30, 2024 and 2023, respectively, and $13.6 million and $13.8 million for the six months ended June 30, 2024 and 2023, respectively. The annual aggregate amortization expense based on the current balance of other intangible assets is estimated to be $27.2 million for 2024, $26.2 million for 2025, $22.2 million for 2026, $20.7 million for 2027, $19.4 million for 2028, and $17.7 million for 2029. Purchased intangible amortization was $6.5 million, $5.0 million after tax, and $6.7 million, $5.2 million after tax, for the three months ended June 30, 2024 and 2023, respectively, and $13.1 million, $10.1 million after tax, and $13.3 million, $10.3 million after tax, for the six months ended June 30, 2024 and 2023, respectively. In addition to the above amortization, the Company recorded amortization expense associated with capitalized software of $11.4 million and $11.1 million for the three months ended June 30, 2024 and 2023, respectively, and $22.7 million and $22.0 million for the six months ended June 30, 2024 and 2023, respectively.
Revenue Recognition	Revenue Recognition Product revenue is recognized from contracts with customers when a customer has obtained control of a product. The Company considers control to have transferred based upon shipping terms. To the extent the Company’s arrangements have a separate performance obligation, revenue related to any post-shipment performance obligation is deferred until completed. Shipping and handling costs charged to customers are included in total net sales and the associated expense is a component of cost of sales. Certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the end customer. Revenue is recognized on these distributor arrangements upon transfer of control to the distributor. Contracts do not contain variable pricing arrangements that are retrospective, except for rebate programs. Rebates are estimated based on expected sales volumes and offset against revenue at the time such revenue is recognized. The Company generally maintains the right to accept or reject a product return in its terms and conditions and also maintains appropriate accruals for outstanding credits. The related provisions for estimated returns and rebates are immaterial to the consolidated financial statements. Certain of the Company’s product arrangements include separate performance obligations, primarily related to installation. Such performance obligations are accounted for separately when the deliverables have stand-alone value and the satisfaction of the undelivered performance obligations is probable and within the Company's control. The allocation of revenue between the performance obligations is based on the observable stand-alone selling prices at the time of the sale in accordance with a number of factors including service technician billing rates, time to install, and geographic location. Software is generally not considered a distinct performance obligation with the exception of a few small software applications. The Company generally does not sell software products without the related hardware instrument as the software is embedded in the product. The Company’s products typically require no significant production, modification, or customization of the hardware or software that is essential to the functionality of the products. Service revenue not under contract is recognized upon the completion of the service performed. Revenue from spare parts sold on a stand-alone basis is recognized when control is transferred to the customer, which is generally at the time of shipment or delivery. Revenue from service contracts is recognized ratably over the contract period using a time-based method. These contracts represent an obligation to perform repair and other services including regulatory compliance qualification, calibration, certification, and preventative maintenance on a customer’s pre-defined equipment over the contract period.
Share - Based Compensation	Share-Based Compensation The Company recognizes share-based compensation expense within selling, general and administrative in the consolidated statements of operations and other comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $4.5 million and $9.3 million of share-based compensation expense for the three and six months ended June 30, 2024, respectively, compared to $4.2 million and $8.2 million for the corresponding periods in 2023.
Research and Development	Research and Development Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred.
Business Combinations Policy [Policy Text Block]	Business Combinations and Asset Acquisitions The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in the Company's consolidated results as of the acquisition date. The purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values and any consideration in excess of the net assets acquired is recognized as goodwill. The determination of the values of the acquired assets and assumed liabilities, including goodwill and intangible assets, require significant judgment. Acquisition transaction costs are expensed when incurred. In circumstances where an acquisition involves a contingent consideration arrangement, the Company recognizes a liability equal to the fair value of the expected contingent payments as of the acquisition date. Subsequent changes in the fair value of the contingent consideration are recorded to other charges (income), net.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In March 2020, January 2021 and December 2022, the FASB issued ASU 2020-04, ASU 2021-01 and ASU 2022-06: Reference Rate Reform, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuance of LIBOR or another referenced rate. The guidance may be applied to any applicable contract entered into before December 31, 2024. The Company amended its credit agreement and cross currency swap agreements in June 2023 to change the interest rate benchmark from LIBOR to SOFR and other non-U.S. dollar references, which did not change the amount or timing of cash flows. As a result, the discontinuation of LIBOR did not have a material impact on the Company's financial statements. In November 2023, the FASB issued ASU 2023-07: Improvements to Reportable Segment Disclosures which requires incremental disclosures about a public entity's reportable segments but does not change the definition of a segment or the guidance for determining reportable segments. The Company will adopt the annual disclosure requirements in 2024 and is currently evaluating the impact of these requirements on the consolidated financial statements. In December 2023, the FASB issued ASU 2023-09: Improvements to Income Tax Disclosures, which enhances income tax disclosures, especially related to the rate reconciliation and income taxes paid information. The Company will adopt the annual disclosure requirements in 2025 and is currently evaluating the impact of these requirements on the consolidated financial statements.
