Changes in the accrued product warranty obligation were as follows: Nine Months Ended September 30, 2021 2020 (In thousands) Balance at the beginning of the period $ 27,839 $ 27,611 Accruals for warranties issued during the period 8,379 9,766 Settlements made during the period (9,112) (11,513) Warranty accruals related to acquired businesses and other during the period 2,227 2,594 Balance at the end of the period $ 29,333 $ 28,458 Accounts Receivable The Company maintains allowances for estimated losses resulting from the inability of customers to meet their financial obligations to the Company. The Company recognizes an allowance for credit losses, on all accounts receivable and contract assets, which considers risk of future credit losses based on factors such as historical experience, contract terms, as well as general and market business conditions, country, and political risk. Balances are written off when determined to be uncollectible. At September 30, 2021, the Company had $768.4 million of accounts receivable, net of allowances of $12.1 million. Changes in the allowance were not material for the three and nine months ended September 30, 2021.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The calculation of basic earnings per share is based on the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding stock options and restricted stock grants). Securities that are anti-dilutive have been excluded and are not significant. The number of weighted average shares used in the calculation of basic earnings per share and diluted earnings per share was as follows: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 (In thousands) Weighted average shares: Basic shares 231,171 229,576 230,811 229,254 Equity-based compensation plans 1,829 1,884 1,901 1,650 Diluted shares 233,000 231,460 232,712 230,904

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the Company’s assets that are measured at fair value on a recurring basis, consistent with the fair value hierarchy, at September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 Fair Value Fair Value (In thousands) Mutual fund investments $ 10,456 $ 8,969 The fair value of mutual fund investments, which are valued as level 1 investments, was based on quoted market prices. The mutual fund investments are shown as a component of investments and other assets on the consolidated balance sheet. For the nine months ended September 30, 2021 and 2020, gains and losses on the investments noted above were not significant. No transfers between level 1 and level 2 investments occurred during the nine months ended September 30, 2021 and 2020. Financial Instruments Cash, cash equivalents and mutual fund investments are recorded at fair value at September 30, 2021 and December 31, 2020 in the accompanying consolidated balance sheet. The following table provides the estimated fair values of the Company’s financial instrument liabilities, for which fair value is measured for disclosure purposes only, compared to the recorded amounts at September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 Recorded Amount Fair Value Recorded Amount Fair Value (In thousands) Long-term debt, net (including current portion) $ (2,302,585) $ (2,467,313) $ (2,347,587) $ (2,550,956) The fair value of net short-term borrowings approximates the carrying value. Net short-term borrowings are valued as level 2 liabilities as they are corroborated by observable market data. The Company’s net long-term debt is all privately held with no public market for this debt, therefore, the fair value of net long-term debt was computed based on comparable current market data for similar debt instruments and is considered a level 3 liability. Foreign Currency At September 30, 2021, the Company had no foreign currency forward contracts outstanding. For the nine months ended September 30, 2021, the Company had no realized or unrealized gains or losses on foreign currency forward contracts. At September 30, 2020, the Company had a Canadian dollar forward contract for a total notional value of 24.0 million Canadian dollars and an immaterial unrealized gain outstanding. For the nine months ended September 30, 2020 realized and unrealized gains and losses on foreign currency forward contracts were not significant. The Company does not typically designate its foreign currency forward contracts as hedges.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Hedging Activities	Hedging Activities The Company has designated certain foreign-currency-denominated long-term borrowings as hedges of the net investment in certain foreign operations. As of September 30, 2021, these net investment hedges included British-pound-and Euro-denominated long-term debt. These borrowings were designed to create net investment hedges in certain designated foreign subsidiaries. The Company designated the British-pound- and Euro-denominated loans referred to above as hedging instruments to offset translation gains or losses on the net investment due to changes in the British pound and Euro exchange rates. These net investment hedges are evidenced by management’s contemporaneous documentation supporting the hedge designation. Any gain or loss on the hedging instruments (the debt) following hedge designation is reported in accumulated other comprehensive income in the same manner as the translation adjustment on the hedged investment based on changes in the spot rate, which is used to measure hedge effectiveness. At September 30, 2021, the Company had $303.0 million of British-pound-denominated loans, which were designated as a hedge against the net investment in British pound functional currency foreign subsidiaries. At September 30, 2021, the Company had $665.7 million in Euro-denominated loans, which were designated as a hedge against the net investment in Euro functional currency foreign subsidiaries. As a result of the British-pound- and Euro-denominated loans designated and 100% effective as net investment hedges, $41.7 million of pre-tax currency remeasurement gains have been included in the foreign currency translation component of other comprehensive income for the nine months ended September 30, 2021.

Acquisitions and Divestiture	Acquisitions and Divestiture Acquisitions The Company spent $1,839.7 million in cash, net of cash acquired, to acquire Magnetrol International ("Magnetrol"), Crank Software, and EGS Automation ("EGS") in March 2021, and NSI-MI Technologies ("NSI-MI") and Abaco Systems, Inc. ("Abaco") in April 2021. Magnetrol is a leading provider of level and flow control solutions for challenging process applications across a diverse set of end markets including medical, pharmaceutical, oil and gas, food and beverage, and general industrial. Crank Software is a leading provider of embedded graphical user interface software and services. EGS is an automation solutions provider that designs and manufactures highly engineered, customized robotic solutions used in critical applications for the medical, food and beverage, and general industrial markets. NSI-MI is a leading provider of radio frequency and microwave test and measurement systems for niche applications across the aerospace, defense, automotive, wireless communications, and research markets. Abaco specializes in open-architecture computing and electronic systems for aerospace, defense, and specialized industrial markets and is a leading provider of mission critical embedded computing systems. Magnetrol, Crank Software, NSI-MI, and Abaco are part of EIG. EGS is part of EMG. The following table represents the allocation of the purchase price for the net assets of the acquisitions based on the estimated fair values at acquisition (in millions): Abaco Other Acquisitions Total (in millions) Property, plant and equipment $ 56.2 $ 39.2 $ 95.4 Goodwill 737.9 244.7 982.6 Other intangible assets 616.9 252.8 869.7 Deferred income taxes (122.2) (30.5) (152.7) Net working capital and other (1) 57.1 (12.4) 44.7 Total cash paid $ 1,345.9 $ 493.8 $ 1,839.7 ________________ (1) Includes $66.2 million in accounts receivable, whose fair value, contractual cash flows and expected cash flows are approximately equal. The amount allocated to goodwill is reflective of the benefits the Company expects to realize from the 2021 acquisitions. Abaco's computing and electronic solutions expand and complement the Company's existing aerospace and defense businesses. NSI-MI strengthens the Company's test and measurement platform. Magnetrol's solutions combined with the Company’s existing Sensors, Test and Calibration business, becomes an industry leading differentiated sensor platform with a broad range of level and flow measurement solutions. Crank Software expands the Company's growing portfolio of software solutions. EGS complements the Company's existing Dunkermotoren business providing highly customizable engineering design and automation capabilities. The Company expects approximately $108 million of the goodwill relating to the 2021 acquisitions will be tax deductible in future years. At September 30, 2021, the purchase price allocated to other intangible assets of $869.7 million consists of $116.1 million of indefinite-lived intangible trade names, which are not subject to amortization. The remaining $753.6 million of other intangible assets consists of $569.9 million of customer relationships, which are being amortized over a period of 15 to 20 years, and $183.7 million of purchased technology, which is being amortized over a period of 11 to 20 years. Amortization expense for each of the next five years for the 2021 acquisitions is expected to approximate $41 million per year. At September 30, 2021, the Company finalized the measurements of certain tangible and intangible assets and liabilities for its 2021 acquisitions of EGS and Crank Software, which had no material impact to the consolidated statement of income. The Company is in the process of finalizing the measurement of the intangible assets and certain tangible assets and liabilities, as well as accounting for income taxes, for its 2021 acquisitions of Abaco, Magnetrol, and NSI-MI. The acquisitions had an immaterial impact on reported net income and diluted earnings per share for the three and nine months ended September 30, 2021. The acquisitions increased net sales by approximately 11% and 6% for the three and nine months ended September 30, 2021, respectively. Had the acquisitions been made at the beginning of 2021 or 2020, pro forma net income and diluted earnings per share for the three and nine months ended September 30, 2021 and 2020, would not have been materially different than the amounts reported. Pro forma net sales would not have been materially different than the amounts reported for the three and nine months ended September 30, 2021 and would have been approximately 10% higher than the reported amounts for the three and nine months ended September 30, 2020. Divestiture The Company completed its sale of Reading Alloys to Kymera International in March 2020 for net cash proceeds of $245.3 million. The sale resulted in a pretax gain of $141.0 million, recorded in Other income, net in the Consolidated

Share Based Compensation Expense Total share-based compensation expense was as follows: Three Months Ended Nine Months Ended 2021 2020 2021 2020 (In thousands) Stock option expense $ 2,768 $ 3,331 $ 10,017 $ 10,330 Restricted stock expense 4,848 4,537 16,765 12,665 Performance restricted stock unit expense 3,812 2,957 8,239 6,883 Total pre-tax expense $ 11,428 $ 10,825 $ 35,021 $ 29,878 Pre-tax share-based compensation expense is included in the consolidated statement of income in either Cost of sales or Selling, general and administrative expenses, depending on where the recipient’s cash compensation is reported. Stock Options The fair value of each stock option grant is estimated on the grant date using a Black-Scholes-Merton option pricing model. The following weighted average assumptions were used in the Black-Scholes-Merton model to estimate the fair values of stock options granted during the periods indicated: Nine Months Ended Year Ended December 31, Expected volatility 24.2 % 22.2 % Expected term (years) 5.0 5.0 Risk-free interest rate 0.85 % 0.52 % Expected dividend yield 0.66 % 1.14 % Black-Scholes-Merton fair value per stock option granted $ 25.63 $ 11.01 The following is a summary of the Company’s stock option activity and related information: Shares Weighted Weighted Aggregate (In thousands) (Years) (In millions) Outstanding at December 31, 2020 3,950 $ 65.16 Granted 552 121.91 Exercised (675) 60.32 Forfeited (96) 84.03 Outstanding at September 30, 2021 3,731 $ 73.95 6.1 $ 186.8 Exercisable at September 30, 2021 2,410 $ 65.00 4.6 $ 142.2 The aggregate intrinsic value of stock options exercised during the nine months ended September 30, 2021 was $40.7 million. The total fair value of stock options vested during the nine months ended September 30, 2021 was $13.7 million. As of September 30, 2021, there was approximately $16.4 million of expected future pre-tax compensation expense related to the 1.3 million non-vested stock options outstanding, which is expected to be recognized over a weighted average period of approximately two years. Restricted Stock The following is a summary of the Company’s non-vested restricted stock activity and related information: Shares Weighted (In thousands) Non-vested restricted stock outstanding at December 31, 2020 701 $ 76.86 Granted 153 122.51 Vested (353) 68.29 Forfeited (37) 93.97 Non-vested restricted stock outstanding at September 30, 2021 464 $ 97.07 The total fair value of restricted stock vested during the nine months ended September 30, 2021 was $24.1 million. As of September 30, 2021, there was approximately $32.6 million of expected future pre-tax compensation expense related to the 0.5 million non-vested restricted shares outstanding, which is expected to be recognized over a weighted average period of approximately two years. Performance Restricted Stock Units In March 2021, the Company granted performance restricted stock units ("PRSU") to officers and certain key management-level employees. The PRSUs vest over a period up to three years from the grant date based on continuous service, with the number of shares earned (0% to 200% of the target award) depending upon the extent to which the Company achieves certain financial and market performance targets measured over the period from January 1 of the year of grant to December 31 of the third year. Half of the PRSUs were valued in a manner similar to restricted stock as the financial targets are based on the Company’s operating results, which represents a performance condition. The grant date fair value of these PRSUs are recognized as compensation expense over the vesting period based on the probable number of awards to vest at each reporting date. The other half of the PRSUs were valued using a Monte Carlo model as the performance target is related to the Company’s total shareholder return compared to a group of peer companies, which represents a market condition. The Company recognizes the grant date fair value of these awards as compensation expense ratably over the vesting period. The following is a summary of the Company’s non-vested performance restricted stock activity and related information: Shares Weighted (In thousands) Non-vested performance restricted stock outstanding at December 31, 2020 264 $ 72.90 Granted 81 121.91 Performance assumption change 1 39 78.20 Vested (88) 78.20 Forfeited (5) 91.58 Non-vested performance restricted stock outstanding at September 30, 2021 291 $ 85.29 _________________________________________ 1 Reflects the number of PRSUs above target levels based on performance metrics. As of September 30, 2021, there was approximately $7.3 million of expected future pre-tax compensation expense related to the 0.3 million non-vested restricted shares outstanding, which is expected to be recognized over a weighted average period of less than one year.

Contingencies

Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Asbestos Litigation The Company (including its subsidiaries) has been named as a defendant in a number of asbestos-related lawsuits. Certain of these lawsuits relate to a business which was acquired by the Company and do not involve products which were manufactured or sold by the Company. In connection with these lawsuits, the seller of such business has agreed to indemnify the Company against these claims (the “Indemnified Claims”). The Indemnified Claims have been tendered to, and are being defended by, such seller. The seller has met its obligations, in all respects, and the Company does not have any reason to believe such party would fail to fulfill its obligations in the future. To date, no judgments have been rendered against the Company as a result of any asbestos-related lawsuit. The Company believes that it has good and valid defenses to each of these claims and intends to defend them vigorously. Environmental Matters Certain historic processes in the manufacture of products have resulted in environmentally hazardous waste by-products as defined by federal and state laws and regulations. At September 30, 2021, the Company is named a Potentially Responsible Party (“PRP”) at 13 non-AMETEK-owned former waste disposal or treatment sites (the “non-owned” sites). The Company is identified as a “de minimis” party in 12 of these sites based on the low volume of waste attributed to the Company relative to the amounts attributed to other named PRPs. In eight of these sites, the Company has reached a tentative agreement on the cost of the de minimis settlement to satisfy its obligation and is awaiting executed agreements. The tentatively agreed-to settlement amounts are fully reserved. In the other four sites, the Company is continuing to investigate the accuracy of the alleged volume attributed to the Company as estimated by the parties primarily responsible for remedial activity at the sites to establish an appropriate settlement amount. At the remaining site where the Company is a non-de minimis PRP, the Company is participating in the investigation and/or related required remediation as part of a PRP Group and reserves have been established to satisfy the Company’s expected obligations. The Company historically has resolved these issues within established reserve levels and reasonably expects this result will continue. In addition to these non-owned sites, the Company has an ongoing practice of providing reserves for probable remediation activities at certain of its current or previously owned manufacturing locations (the “owned” sites). For claims and proceedings against the Company with respect to other environmental matters, reserves are established once the Company has determined that a loss is probable and estimable. This estimate is refined as the Company moves through the various stages of investigation, risk assessment, feasibility study and corrective action processes. In certain instances, the Company has developed a range of estimates for such costs and has recorded a liability based on the best estimate. It is reasonably possible that the actual cost of remediation of the individual sites could vary from the current estimates and the amounts accrued in the consolidated financial statements; however, the amounts of such variances are not expected to result in a material change to the consolidated financial statements. In estimating the Company’s liability for remediation, the Company also considers the likely proportionate share of the anticipated remediation expense and the ability of the other PRPs to fulfill their obligations. Total environmental reserves at September 30, 2021 and December 31, 2020 were $33.8 million and $32.4 million, respectively, for both non-owned and owned sites. For the nine months ended September 30, 2021, the Company recorded $7.3 million in reserves. Additionally, the Company spent $5.9 million on environmental matters for the nine months ended September 30, 2021. The Company’s reserves for environmental liabilities at September 30, 2021 and December 31, 2020 included reserves of $4.8 million and $7.4 million, respectively, for an owned site acquired in connection with the 2005 acquisition of HCC Industries (“HCC”). The Company is the designated performing party for the performance of remedial activities for one of several operating units making up a Superfund site in the San Gabriel Valley of California. The Company has agreements with other former owners of certain of its acquired businesses, as well as new owners of previously owned businesses. Under certain of the agreements, the former or new owners retained, or assumed and agreed to indemnify the Company against, certain environmental and other liabilities under certain circumstances. The Company and some of these other parties also carry insurance coverage for some environmental matters. To date, these parties have met their obligations in all material respects. The Company believes it has established reserves for the environmental matters described above, which are sufficient to perform all known responsibilities under existing claims and consent orders. The Company has no reason to believe that other third parties would fail to perform their obligations in the future. In the opinion of management, based on presently
