NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(amounts in millions, except share and per share data, unless otherwise noted)

​

Note 1—Basis of Presentation and Principles of Consolidation

​

The Condensed Consolidated Balance Sheets as of June 30, 2021 and December 31, 2020, the related Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2021 and 2020, and the related Condensed Consolidated Statements of Cash Flow for the six months ended June 30, 2021 and 2020, include the accounts of Amphenol Corporation and its subsidiaries (“Amphenol,” the “Company,” “we,” “our,” or “us”). All material intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements included herein are unaudited. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, including normal recurring adjustments considered necessary for a fair presentation of the results, in conformity with accounting principles generally accepted in the United States of America. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year. These condensed consolidated financial statements and the related notes should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “2020 Annual Report”).

​

Stock Split

​

On January 27, 2021, the Company announced that its Board of Directors approved a two-for-one split of the Company’s Common Stock. The stock split was effected in the form of a stock dividend paid to shareholders of record as of the close of business on February 16, 2021. The additional shares were distributed on March 4, 2021, and the Company’s Common Stock began trading on a split-adjusted basis on March 5, 2021. As a result of the stock split, shareholders received one additional share of Amphenol Common Stock, $0.001 par value, for each share held as of the record date.

​

All current and prior year data presented in the accompanying Condensed Consolidated Financial Statements and notes thereto in this Form 10-Q, including but not limited to, number of shares and per share information, stock-based compensation data including stock options and restricted shares and related per share data, basic and diluted earnings per share, and dividends per share amounts, have been adjusted to reflect the effect of the stock split. As a result of the stock split, certain prior period amounts have been reclassified to conform to the current period presentation in the Condensed Consolidated Financial Statements and accompanying notes herein. The impact to the Condensed Consolidated Balance Sheets, as well as the rollforward of consolidated changes in equity included in Note 7 herein, was an increase of $0.3 to Common Stock, with an offsetting decrease in Additional paid-in capital, which has been retroactively adjusted for all periods presented.

​

While the stock split did not change the number of authorized common shares of the Company, in May 2021, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to increase the number of authorized shares of Common Stock, which amendment was filed and became effective on May 21, 2021. Refer to Note 7 herein for further details related to the increase in the number of shares of Common Stock authorized for issuance as a result of this amendment.

​

Discontinued Operations

​

The Company reports an operation’s assets and liabilities separately as “held for sale” when (1) management, having the authority to approve the action, commits to a plan to sell the discontinued operation, the plan of which is unlikely to have any significant changes or to be withdrawn, (2) the completed sale is probable within one year and (3) an active program to locate a buyer has been initiated with the operation actively marketed for sale at a price that is reasonable in relation to its current fair value and for immediate sale in its present condition. In December 2020, the Company signed a definitive agreement to acquire MTS Systems Corporation (Nasdaq: MTSC) (“MTS”) as more fully

Table of Contents

discussed in Note 11 herein. On January 19, 2021, the Company entered into a definitive agreement to sell the MTS Test & Simulation (“MTS T&S”) business to Illinois Tool Works Inc. (NYSE: ITW). The Company closed on the acquisition of MTS on April 7, 2021. The Company expects to close on the sale of the MTS T&S business as soon as all required regulatory approvals have been received and other customary closing conditions have been satisfied, which the Company expects to be within the one-year period outlined above. The Company concluded that the MTS T&S business met the “held for sale” criteria upon the closing of the MTS acquisition and, as such, the assets and liabilities are presented as held for sale and classified as current as of June 30, 2021 in the Condensed Consolidated Balance Sheets and accompanying Notes herein. The financial results and cash flows associated with the MTS T&S business are also accounted for as discontinued operations in the accompanying Condensed Consolidated Statements of Income and Statements of Cash Flow, respectively, for all current year periods presented. The comprehensive income associated with discontinued operations is not material and has not been separately presented in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2021.

​

Refer to Note 11 herein for further information related to the acquisition of MTS, along with Note 12 herein for further discussion of the Company’s discontinued operations associated with the MTS T&S business including the Company’s planned divestiture thereof.

​

Note 2—New Accounting Pronouncements

​

Recently Adopted Accounting Standards and Final SEC Rules

​

In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplified income tax accounting in various areas. The Company has evaluated and adopted ASU 2019-12 on January 1, 2021, which did not have a material impact on our consolidated financial statements.

​

In May 2020, the Securities and Exchange Commission (the “SEC”) issued a new rule regarding the financial statement requirements for acquisitions and dispositions of a business, which included, among other things, amending (i) certain criteria in the significance tests for acquired or to-be-acquired businesses, (ii) related pro forma financial information requirements, including its form and content, and (iii) related disclosure requirements, including the number of acquiree financial statement periods required to be presented in SEC filings. The final rule was effective for fiscal years beginning after December 31, 2020, with early application permitted. The Company evaluated and adopted this SEC final rule on January 1, 2021, which, to date, has not had a material impact on our condensed consolidated financial statements. Its impact on any future SEC filings will be dependent on the size of future business combinations and/or divestitures.

​

Recently Issued Accounting Standards and Final SEC Rules Not Yet Adopted

​

The United Kingdom’s Financial Conduct Authority (the “FCA”), which regulates the London Interbank Offered Rate (“LIBOR”), announced in July 2017 its intent to phase out the use of LIBOR by the end of 2021. In December 2020, the ICE Benchmark Administration published a consultation on its intention to extend the publication of certain U.S. dollar LIBOR (“USD LIBOR”) rates until June 30, 2023. Subsequently in March 2021, the FCA announced some USD LIBOR tenors (overnight, 1-month, 3-month, 6-month and 12-month) will continue to be published until June 30, 2023. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, identified the Secured Overnight Financing Rate (the “SOFR”) as its preferred benchmark alternative to USD LIBOR. The SOFR represents a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is calculated based on directly observable U.S. Treasury-backed repurchase transactions. In March 2020, in response to this transition, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued by reference rate reform, and addresses operational issues likely to arise in modifying contracts to replace discontinued reference rates with new rates. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. In January 2021, the FASB also issued ASU 2021-01 Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”), which permits entities to elect certain optional expedients and exceptions when accounting for derivatives and certain hedging relationships affected by

changes in interest rates and the transition. The Company is evaluating the potential impact of the replacement of LIBOR from both a risk management and financial reporting perspective. Our current portfolio of debt and financial instruments tied to LIBOR consists primarily of our Revolving Credit Facility (as defined below), which had no outstanding borrowings as of June 30, 2021. We do not currently believe that this transition will have a material impact on our financial condition, results of operations or cash flows.

​

In November 2020, the SEC issued a new rule that modernizes and simplifies various aspects and financial disclosure requirements in Regulation S-K, specifically related to Item 301 “Selected Financial Data”, Item 302 “Supplementary Financial Information” and Item 303 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”). The intent of this new rule is to (i) eliminate duplicative disclosures, (ii) enhance and promote more principles-based MD&A disclosures with the objective of making them more meaningful for investors, all while (iii) simplifying the compliance requirements and efforts for registrants, by providing them with the flexibility to present management’s perspective on the registrant’s financial condition and results of operations. While most of the changes involve reducing or eliminating previously required information and disclosures, the rule does expand the disclosure requirements surrounding certain aspects of the various items in Regulation S-K discussed above. The final rule was published in the Federal Register on January 11, 2021, is effective thirty days after its publication date, or February 10, 2021, and registrants are required to comply with this final rule in the registrant’s first fiscal year ending on or after the date that is 210 days after the publication date (August 9, 2021). The Company has evaluated this SEC final rule, and we plan to incorporate the requirements and amendments of this SEC rule, in its entirety, as part of our Form 10-K for the year ending December 31, 2021. The application of this new SEC rule is not expected to have a material impact on our future SEC filings.

Revolving Credit Facility

​

The Company has a $2,500.0 unsecured credit facility (the “Revolving Credit Facility”), which matures January 2024 and gives the Company the ability to borrow, in various currencies, at a spread over LIBOR. The Company may utilize the Revolving Credit Facility for general corporate purposes. At June 30, 2021 and December 31, 2020, there were no outstanding borrowings under the Revolving Credit Facility. The carrying value of any borrowings under the Revolving Credit Facility would approximate their fair value due primarily to their market interest rates and would be classified as Level 2 in the fair value hierarchy (Note 5). Any outstanding borrowings under the Revolving Credit Facility are classified as long-term debt in the accompanying Condensed Consolidated Balance Sheets. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants. At June 30, 2021, the Company was in compliance with the financial covenants under the Revolving Credit Facility.

Commercial Paper Programs

​

The Company has a commercial paper program pursuant to which the Company may issue short-term unsecured commercial paper notes (the “USCP Notes”) in one or more private placements in the United States (the “U.S. Commercial Paper Program”). The maturities of the USCP Notes vary, but may not exceed 397 days from the date of issue. The USCP Notes are sold under customary terms in the commercial paper market and may be issued at par or a discount therefrom, and bear varying interest rates on a fixed or floating basis. The maximum aggregate principal amount outstanding of USCP Notes at any time is $2,500.0. As of June 30, 2021, the amount of USCP Notes outstanding was $1,401.0, with a weighted average interest rate of 0.21%. On April 7, 2021, a combination of borrowings under the U.S. Commercial Paper Program and cash and cash equivalents on hand were used to fund the acquisition of MTS. Refer to Note 11 herein for further discussion of the acquisition of MTS.

​

The Company and one of its wholly owned European subsidiaries (collectively, the “Euro Issuer”) also has a commercial paper program (the “Euro Commercial Paper Program” and, together with the U.S. Commercial Paper Program, the “Commercial Paper Programs”) pursuant to which the Euro Issuer may issue short-term unsecured commercial paper notes (the “ECP Notes” and, together with the USCP Notes, “Commercial Paper”), which are guaranteed by the Company and are to be issued outside of the United States. The maturities of the ECP Notes will vary, but may not exceed 183 days from the date of issue. The ECP Notes are sold under customary terms in the

commercial paper market and may be issued at par or a discount therefrom or a premium thereto and bear varying interest rates on a fixed or floating basis. The ECP Notes may be issued in Euros, Sterling, U.S. dollars or other currencies. The maximum aggregate principal amount outstanding of ECP Notes at any time is $2,000.0. As of June 30, 2021, there were no ECP Notes outstanding.

​

Amounts available under the Commercial Paper Programs may be borrowed, repaid and re-borrowed from time to time. In conjunction with the Revolving Credit Facility, the authorization from the Company’s Board of Directors limits the maximum principal amount outstanding of USCP Notes, ECP Notes, and any other commercial paper or similar programs, along with outstanding amounts under the Revolving Credit Facility, at any time to $2,500.0 in the aggregate. The Commercial Paper Programs are rated A-2 by Standard & Poor’s and P-2 by Moody’s and are currently backstopped by the Revolving Credit Facility, as amounts undrawn under the Company’s Revolving Credit Facility are available to repay Commercial Paper, if necessary. Net proceeds of the issuances of Commercial Paper are expected to be used for general corporate purposes. The Commercial Paper is classified as long-term debt in the accompanying Condensed Consolidated Balance Sheets since the Company has the intent and ability to refinance the Commercial Paper on a long-term basis using the Company’s Revolving Credit Facility. The Commercial Paper is actively traded and is therefore classified as Level 1 in the fair value hierarchy (Note 5). The carrying value of Commercial Paper borrowings approximates their fair value.

U.S. Senior Notes

​

On February 20, 2020, the Company issued $400.0 principal amount of unsecured 2.050% Senior Notes due March 1, 2025 at 99.829% of face value (the “2025 Senior Notes”). The 2025 Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness. Interest on the 2025 Senior Notes is payable semiannually on March 1 and September 1 of each year, commencing on September 1, 2020. Prior to February 1, 2025, the Company may, at its option, redeem some or all of the 2025 Senior Notes at any time by paying the redemption price (which may include a make-whole premium), plus accrued and unpaid interest, if any, to, but not including, the date of redemption. If redeemed on or after February 1, 2025, the Company may, at its option, redeem some or all of the 2025 Senior Notes at any time by paying the redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. On April 1, 2020, the Company used the net proceeds from the 2025 Senior Notes to repay the $400.0 principal amount of unsecured 2.20% Senior Notes due April 1, 2020 upon maturity.

​

All of the Company’s outstanding senior notes in the United States (the “U.S. Senior Notes”) are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness. Interest on each series of U.S. Senior Notes is payable semiannually. The Company may, at its option, redeem some or all of any series of U.S. Senior Notes at any time subject to certain terms and conditions, which include paying 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of redemption, and, with certain exceptions, a make-whole premium. The fair value of each series of U.S. Senior Notes is based on recent bid prices in an active market and is therefore classified as Level 1 in the fair value hierarchy (Note 5). The remaining principal amounts outstanding associated with the Company’s 3.125% Senior Notes due in September 2021 and 4.00% Senior Notes due in February 2022 are each recorded, net of the related unamortized discount and debt issuance costs, within Current portion of long-term debt in the accompanying Condensed Consolidated Balance Sheets as of June 30, 2021. The U.S. Senior Notes contain certain financial and non-financial covenants. At June 30, 2021, the Company was in compliance with the financial covenants under its U.S. Senior Notes.

​

Euro Senior Notes

​

On May 4, 2020, the Euro Issuer issued €500.0 (approximately $545.4 at date of issuance) principal amount of unsecured 0.750% Senior Notes due May 4, 2026 at 99.563% of face value (the “2026 Euro Notes” or the “0.750% Euro Senior Notes”, collectively with the 2.000% Euro Senior Notes due October 2028, the “Euro Notes”, and the Euro Notes collectively with the U.S. Senior Notes, the “Senior Notes”). The 2026 Euro Notes are unsecured and rank equally in right of payment with the Euro Issuer’s other unsecured senior indebtedness, and are fully and unconditionally guaranteed on a senior unsecured basis by the Company. Interest on the 2026 Euro Notes is payable annually on May 4 of each year, commencing on May 4, 2021. Prior to February 4, 2026, the Company may, at its option, redeem some or

all of the 2026 Euro Notes at any time by paying the redemption price (which may include a make-whole premium), plus accrued and unpaid interest, if any, to, but not including, the date of redemption. If redeemed on or after February 4, 2026, the Company may, at its option, redeem some or all of the 2026 Euro Notes at any time by paying the redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of redemption. The Company used the net proceeds from the 2026 Euro Notes to repay amounts outstanding under the Revolving Credit Facility.

​

The Company’s Euro Notes are unsecured and rank equally in right of payment with the Euro Issuer’s other unsecured senior indebtedness, and are fully and unconditionally guaranteed on a senior unsecured basis by the Company. Interest on each series of Euro Notes is payable annually. The Company may, at its option, redeem some or all of any series of Euro Notes at any time subject to certain terms and conditions, which include paying 100% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, and, with certain exceptions, a make-whole premium. The fair value of each series of Euro Notes is based on recent bid prices in an active market and is therefore classified as Level 1 in the fair value hierarchy (Note 5). The Euro Notes contain certain financial and non-financial covenants. At June 30, 2021, the Company was in compliance with the financial covenants under its Euro Notes.

​

Note 5—Fair Value Measurements

​

Fair value is determined based on 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. These requirements establish market or observable inputs as the preferred source of values. Assumptions based on hypothetical transactions are used in the absence of market inputs. The Company does not have any non-financial instruments accounted for at fair value on a recurring basis.

​

The valuation techniques required are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:

​

Level 1 Quoted prices for identical instruments in active markets.

​

Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

​

Level 3 Significant inputs to the valuation model are unobservable.

​

The Company believes that the assets or liabilities currently subject to such standards with fair value disclosure requirements are primarily debt instruments, pension plan assets, short-term investments, and derivative instruments. Each of these assets and liabilities is discussed below, with the exception of debt instruments and pension plan assets, which are covered in Note 4 and Note 10, respectively, herein, in addition to the Notes to Consolidated Financial Statements in the 2020 Annual Report. Substantially all of the Company’s short-term investments consist of certificates of deposit with original maturities of twelve months or less and as such, are considered as Level 1 in the fair value hierarchy as they are traded in active markets for identical assets. The carrying amounts of these instruments, the majority of which are in non-U.S. bank accounts, approximate their fair value. The Company’s derivative instruments primarily consist of foreign exchange forward contracts, which are valued using bank quotations based on market observable inputs such as forward and spot rates and are therefore classified as Level 2 in the fair value hierarchy. The

impact of the credit risk related to these financial assets is immaterial. The fair values of the Company’s financial and non-financial assets and liabilities subject to such standards as of June 30, 2021 and December 31, 2020 are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Fair Value Measurements
​ | ​ | ​ | ​ | ​ | Quoted Prices in | ​ | Significant | ​ | Significant

June 30, 2021: | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Short-term investments | ​ | $ | 33.2 | ​ | $ | 33.2 | ​ | $ | — | ​ | $ | —

Total | ​ | $ | 33.4 | ​ | $ | 36.1 | ​ | $ | (2.7) | ​ | $ | —

​

As of June 30, 2021, the fair value of such forward contracts in the table above consisted of (i) two outstanding foreign exchange forward contracts accounted for as cash flow hedges, with each expiring in 2021, (ii) various outstanding foreign exchange forward contracts accounted for as net investment hedges and (iii) various outstanding foreign exchange forward contracts that are not designated as hedging instruments. The amounts recognized in Accumulated other comprehensive income (loss) associated with foreign exchange forward contracts and the amounts reclassified from Accumulated other comprehensive income (loss) to foreign exchange gain (loss), included in Cost of sales in the accompanying Condensed Consolidated Statements of Income during the three and six months ended June 30, 2021 and 2020, were not material. The fair values of the Company’s forward contracts are recorded within Prepaid expenses and other current assets, Other long-term assets, Other accrued expenses and Other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets, depending on their value and remaining contractual period.

​

As further discussed in Note 12 herein, the MTS T&S business met the held for sale criteria upon the acquisition of MTS on April 7, 2021. As a result, the disposal group was measured at fair value less costs to sell, which is considered a Level 3 fair value measurement based on the transaction’s expected consideration. The Company reassessed the fair value of these assets held for sale and liabilities held for sale as of June 30, 2021 and noted that the carrying value of the disposal group did not exceed its fair value less costs to sell.

​

With the exception of the fair value of the assets acquired and liabilities assumed in connection with acquisition accounting as well as the assets held for sale and liabilities held for sale discussed above, the Company does not have any other significant financial or non-financial assets and liabilities that are measured at fair value on a non-recurring basis.

​

For the three months ended June 30, 2021 and 2020, stock option exercise activity had the impact of decreasing our Provision for income taxes by $19.3 and $12.4, respectively, and decreasing our effective tax rate by 430 basis points and 380 basis points, respectively, due to the recognition of excess tax benefits within Provision for income taxes in the accompanying Condensed Consolidated Statements of Income. For the six months ended June 30, 2021 and 2020, stock option exercise activity had the impact of decreasing our Provision for income taxes by $22.0 and $17.4, respectively, and decreasing our effective tax rate by 250 basis points and 280 basis points, respectively. For the three and six months ended June 30, 2021, acquisition-related expenses had the effect of increasing the effective tax rate by approximately 60

basis points and 30 basis points, respectively, and a discrete tax benefit of $14.9 related to the settlement of uncertain tax positions in certain non-U.S. jurisdictions had the effect of decreasing the effective tax rate by 330 basis points and 170 basis points, respectively. For the six months ended June 30, 2020, the effective tax rate also includes a discrete tax benefit related to the settlements of refund claims in a non-U.S. jurisdiction and the resulting adjustments to deferred taxes, which had the impact of decreasing our Provision for income taxes and effective tax rate by $19.9 and 320 basis points, respectively.

​

On December 22, 2017, the United States federal government enacted the Tax Cuts and Jobs Act (“Tax Act”), marking a change from a worldwide tax system to a modified territorial tax system in the United States. As part of this change, the Tax Act, among other changes, provides for a transition tax (“Transition Tax”) related to the deemed repatriation of the accumulated unremitted earnings and profits of the Company’s foreign subsidiaries. The Company paid its fourth annual installment of the Transition Tax, net of applicable tax credits and deductions, in the second quarter of 2021, and will pay the balance of the Transition Tax, net of applicable tax credits and deductions, over the remainder of the eight-year period ending 2025, as permitted under the Tax Act. The current and long-term portions of the Transition Tax are recorded in Accrued income taxes and Other long-term liabilities, respectively, on the Condensed Consolidated Balance Sheets as of June 30, 2021 and December 31, 2020.

​

The Company operates in the U.S. and numerous foreign taxable jurisdictions, and at any point in time has numerous audits underway at various stages of completion. With few exceptions, the Company is subject to income tax examinations by tax authorities for the years 2017 and after. The Company is generally not able to precisely estimate the ultimate settlement amounts or timing until the close of an audit. The Company evaluates its tax positions and establishes liabilities for uncertain tax positions that may be challenged by tax authorities and may not be fully sustained, despite the Company’s belief that the underlying tax positions are fully supportable. As of June 30, 2021, the amount of unrecognized tax benefits, including penalties and interest, which if recognized would impact the effective tax rate, was approximately $157.1. Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including the progress of tax audits and the closing of statutes of limitations. Based on information currently available, management anticipates that over the next twelve-month period, audit activity could be completed and statutes of limitations may close relating to existing unrecognized tax benefits of approximately $8.3.

Note 7—Shareholders’ Equity and Noncontrolling Interests

​

Net income from continuing operations attributable to noncontrolling interests is classified below net income from continuing operations. Earnings per share is determined after the impact of the noncontrolling interests’ share in net income of the Company. In addition, the equity attributable to noncontrolling interests is presented as a separate caption within equity.

Authorized Shares for Issuance

​

On May 19, 2021, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation, which increased the total number of shares of Class A Common Stock, $0.001 par value (“Common Stock”) that the Company is authorized to issue to 2,000,000,000 shares, an increase of 1,000,000,000 shares from the amount previously authorized.

​

Stock Repurchase Programs

​

On April 24, 2018, the Company’s Board of Directors authorized a stock repurchase program under which the Company could purchase up to $2,000.0 of the Company’s Common Stock during the three-year period ending April 24, 2021 (the “2018 Stock Repurchase Program”) in accordance with the requirements of Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). During the three and six months ended June 30, 2021, the Company repurchased 0.8 million and 3.1 million shares of its Common Stock for $51.0 and $203.8, respectively, under the 2018 Stock Repurchase Program. As a result of these purchases, the Company completed all purchases authorized under the 2018 Stock Repurchase Program and, therefore, the 2018 Stock Repurchase Program has terminated. Of the total repurchases made during the first six months of 2021, 0.3 million shares, or $19.8, have been retained in Treasury stock at the time of repurchase; the remaining 2.8 million shares, or $184.0, have been retired by the Company. The Company did no t repurchase any of its Common Stock during the three months ended June 30, 2020. During the six months ended June 30, 2020, the Company repurchased 5.4 million shares of its Common Stock for $257.2 under the 2018 Stock Repurchase Program. All of the shares repurchased during the first six months of 2020 were retired by the Company.

​

On April 27, 2021, the Company’s Board of Directors authorized a new stock repurchase program under which the Company may purchase up to $2,000.0 of the Company’s Common Stock during the three-year period ending April 27, 2024 (the “2021 Stock Repurchase Program”) in accordance with the requirements of Rule 10b-18 of the Exchange Act. During the three months ended June 30, 2021, the Company repurchased 1.7 million shares of its Common Stock for $116.3 under the 2021 Stock Repurchase Program. All of the shares repurchased under the 2021 Stock Repurchase Program during the second quarter of 2021 have been or will be retired by the Company. From July 1, 2021 to July 27, 2021, the Company repurchased 0.7 million additional shares of its Common Stock for $48.8 under the 2021 Stock Repurchase Program, and has remaining authorization to purchase up to $1,834.9 of its Common Stock under the 2021 Stock Repurchase Program. The price and timing of any future purchases under the 2021 Stock Repurchase Program will depend on a number of factors such as levels of cash generation from operations, the volume of stock option exercises by employees, cash requirements for acquisitions, dividends paid, economic and market conditions and the price of the Company’s common stock.

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended June 30, | ​ | Six Months Ended June 30, | ​

Note 8—Stock-Based Compensation

​

For the three months ended June 30, 2021 and 2020, the Company’s Income from continuing operations before income taxes was reduced for stock-based compensation expense of $20.0 and $16.6, respectively. In addition, for the three months ended June 30, 2021 and 2020, the Company recognized aggregate income tax benefits of $21.8 and $14.3, respectively, in Provision for income taxes in the accompanying Condensed Consolidated Statements of Income associated with stock-based compensation. These aggregate income tax benefits during the three months ended June 30, 2021 and 2020 include excess tax benefits of $19.3 and $12.4, respectively, from option exercises.

​

For the six months ended June 30, 2021 and 2020, the Company’s Income from continuing operations before income taxes was reduced for stock-based compensation expense of $39.0 and $32.0, respectively. In addition, for the six months ended June 30, 2021 and 2020, the Company recognized aggregate income tax benefits of $26.4 and $21.1, respectively, in Provision for income taxes in the accompanying Condensed Consolidated Statements of Income associated with stock-based compensation. These aggregate income tax benefits during the six months ended June 30, 2021 and 2020 include excess tax benefits of $22.0 and $17.4, respectively, from option exercises.

​

The impact associated with recognizing excess tax benefits from option exercises in the provision for income taxes on our consolidated financial statements could result in significant fluctuations in our effective tax rate in the future, since the provision for income taxes will be impacted by the timing and intrinsic value of future stock-based compensation award exercises.

​

Stock-based compensation expense includes the estimated effects of forfeitures, which are adjusted over the requisite service period to the extent actual forfeitures differ or are expected to differ from such estimates. Changes in estimated forfeitures are recognized in the period of change and impact the amount of expense to be recognized in future periods. The expense incurred for stock-based compensation plans is included in Selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Income.

​

Stock Options

​

In May 2017, the Company adopted the 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (the “2017 Employee Option Plan”), which provided for the issuance of 60,000,000 shares. In March 2021, the Company’s Board of Directors authorized and approved the Amended and Restated 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (the “Amended 2017 Employee Option Plan” and, together with the 2017 Employee Option Plan, the “2017 Option Plan”), which among other things, increased the number of shares reserved for issuance under the plan by 40,000,000 shares. The Amended 2017 Employee Option Plan was approved by the Company’s shareholders and became effective on May 19, 2021. As of June 30, 2021, there were 42,932,620 shares of Common Stock available for the granting of additional stock options under the Amended 2017 Employee Option Plan. Prior to the approval of the 2017 Employee Option Plan, the Company issued stock options under the 2009 Stock

​

During the three and six months ended June 30, 2021 and 2020, the following activity occurred under the Company’s option plans:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Three Months Ended |  | Six Months Ended |
​ | ​ | June 30, | ​ | June 30, | ​

Total fair value of stock options vested | ​ |  | 70.4 | ​ |  | 60.8 | ​ |  | 70.8 | ​ |  | 61.4 | ​

​

As of June 30, 2021, the total compensation cost related to non-vested options not yet recognized was approximately $234.3 with a weighted average expected amortization period of 3.72 years.

​

The grant-date fair value of each option grant under the 2009 Employee Option Plan and the 2017 Option Plan is estimated using the Black-Scholes option pricing model. The grant-date fair value of each share grant is determined based on the closing share price of the Company’s Common Stock on the date of the grant. The fair value is then

17

Table of Contents

amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model for option grants requires management to make certain assumptions with respect to selected model inputs. Expected share price volatility is calculated based on the historical volatility of the Common Stock and implied volatility derived from related exchange traded options. The average expected life is based on the contractual term of the option and expected exercise and historical experience. The risk-free interest rate is based on U.S. Treasury zero-coupon issuances with a remaining term equal to the expected life assumed at the date of grant. The expected annual dividend per share is based on the Company’s dividend rate.

​

Restricted Shares

​

In 2012, the Company adopted the 2012 Restricted Stock Plan for Directors of Amphenol Corporation (the “2012 Directors Restricted Stock Plan”).

Note 9—Earnings Per Share

​

Basic earnings per share (“EPS”) is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of common shares outstanding. Diluted EPS is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of outstanding common shares, including dilutive common shares, the dilutive effect of which relates to stock options. A reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding, along with the earnings per share (basic and

Note 10—Benefit Plans and Other Postretirement Benefits

​

The Company and certain of its domestic subsidiaries have defined benefit pension plans (the “U.S. Plans”), which cover certain U.S. employees and which represent the majority of the plan assets and benefit obligations of the aggregate defined benefit plans of the Company. The U.S. Plans’ benefits are generally based on years of service and compensation and are generally noncontributory. The majority of U.S. employees are not covered by the U.S. Plans and are covered by defined contribution plans. Certain foreign subsidiaries have defined benefit plans covering their employees (the “Foreign Plans” and, together with the U.S. Plans, the “Plans”).

Note 11—Acquisitions

​

2021 Acquisitions

​

During the first six months of 2021, the Company completed six acquisitions for approximately $1,531.0, net of cash acquired. Five of the acquisitions have been included in the Interconnect Products and Assemblies segment, while one acquisition has been included in the Cable Products and Solutions segment. The Company is in the process of completing its analyses of the fair value of the assets acquired and liabilities assumed. The Company anticipates that the final assessments of values will not differ materially from the preliminary assessments. The operating results of the 2021 acquisitions have been included in the Condensed Consolidated Statements of Income since their respective dates of acquisition. Pro forma financial information, as well as further details regarding the purchase price allocation related to these acquisitions, has not been presented, since these acquisitions were not material, either individually or in the aggregate, to the Company’s financial results.

​

Acquisition of MTS Systems Corporation

​

On December 9, 2020, Amphenol announced that the Company entered into a definitive agreement under which Amphenol would acquire MTS Systems Corporation (Nasdaq: MTSC) (“MTS”) for $58.50 per share in cash. MTS is a leading global supplier of precision sensors, advanced test systems and motion simulators. MTS was historically organized into two business segments: Sensors (“MTS Sensors”) and Test & Simulation (“MTS T&S”). The MTS Sensors segment represents a highly complementary offering of high-technology, harsh environment sensors sold into diverse end markets and applications. The MTS Sensors business further expands the Company’s range of sensor and sensor-based products across a wide array of industries and is reported as part of our continuing operations and within

our Interconnect Products and Assemblies segment. On January 19, 2021 and prior to the closing of the MTS acquisition, the Company entered into a definitive agreement to sell the MTS T&S business to Illinois Tool Works Inc. (“ITW”) (NYSE: ITW). Refer to Note 12 herein for further details related to the planned divestiture of the MTS T&S business.

​

On April 7, 2021, the Company completed its acquisition of MTS for a purchase price of approximately $1,300, net of cash acquired and including the repayment of certain outstanding debt and liabilities at closing. The MTS acquisition was funded through a combination of borrowings under the U.S. Commercial Paper Program, as discussed in Note 4 herein, and cash and cash equivalents on hand. In addition to the purchase price, the Company also assumed MTS’s then-outstanding $350.0 principal amount of senior notes due August 15, 2027, which the Company repaid and settled shortly after the closing for approximately $387.3, which included accrued interest and a make-whole premium incurred as a result of the early extinguishment of the senior notes.

​

The Company has begun the acquisition accounting related to MTS, specifically the allocation of the MTS purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed of MTS based upon their estimated fair values. This preliminary purchase price allocation is being performed separately for the MTS Sensors business and the MTS T&S business, the latter of which is being accounted for as discontinued operations and whose assets acquired, including associated goodwill, and liabilities assumed are reported as current assets held for sale and liabilities held for sale on the accompanying Condensed Consolidated Balance Sheets.

​

While the Company is in the process of completing its analyses of the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed, as of June 30, 2021, the MTS acquisition resulted in the recognition of $740.3 of goodwill, $54.0 of indefinite-lived tradename intangible assets and $183.4 of definite-lived intangible assets, each associated with the MTS Sensors business. The definite-lived intangible assets are comprised of customer relationships, proprietary technology, and backlog of $128.1, $39.1 and $16.2, respectively, and are amortized based upon the underlying pattern of economic benefit with weighted-average useful lives of 11 years, 15 years and 0.25 years, respectively. Other than these intangible assets, the remainder of the purchase price has been allocated to other identifiable assets acquired and liabilities assumed. As part of acquisition accounting, the Company also recorded $61.0 of deferred tax liabilities associated with certain basis differences, which the Company anticipates recovery for tax purposes by the end of 2021. The excess purchase price over the fair value of the underlying assets acquired (net of liabilities assumed) was allocated to goodwill, which primarily represents the value of assembled workforce and the anticipated cost savings and efficiencies associated with the integration of MTS, along with other intangible assets acquired that do not qualify for separate recognition. The Company does no t expect any of the recognized goodwill associated with the acquisition of MTS to be deductible for tax purposes. Since the current purchase price allocation is based on preliminary assessments made by management as of June 30, 2021, the acquisition accounting for MTS is subject to final adjustment and it is possible that the final assessment of values may differ from this preliminary assessment. With the exception of the MTS T&S business, which has been classified and reported as discontinued operations as discussed further in Note 12 herein, the operating results for MTS have been included within continuing operations in the Condensed Consolidated Statements of Income since the acquisition date.

​

2020 Acquisitions

​

During the year ended December 31, 2020, the Company completed two acquisitions, which are included in the Interconnect Products and Assemblies segment, for approximately $50.4, net of cash acquired. While the Company has completed the acquisition accounting for one of the acquisitions in 2020, the Company is in the process of completing the analyses of the fair value of the assets acquired and liabilities assumed for the other 2020 acquisition. The Company anticipates that the final assessments of values will not differ materially from the preliminary assessments. Pro forma financial information, as well as further details regarding the purchase price allocation related to these acquisitions, has not been presented, since these acquisitions were not material, either individually or in the aggregate, to the Company’s financial results.

Acquisition-related Expenses

​

During the three and six months ended June 30, 2021, the Company incurred $55.4 ($44.6 after-tax) of acquisition-related expenses, primarily comprised of transaction, severance, restructuring and certain non-cash costs related to the MTS acquisition. Such acquisition-related expenses are separately presented in the accompanying Condensed Consolidated Statements of Income.

​

Note 12—Discontinued Operations

​

Planned Divestiture of MTS T&S Business

​

On January 19, 2021 and prior to the closing of the MTS acquisition, the Company entered into a definitive agreement to sell the MTS T&S business to ITW. The agreed-upon sale price is approximately $750, subject to certain post-closing adjustments and excluding any outstanding net debt assumed by Amphenol related to the MTS T&S business. The Company expects to close on the sale of the MTS T&S business upon the receipt of all required regulatory approvals and the satisfaction of other customary closing conditions, which is expected to be within one year of the date of the acquisition of MTS.

​

Since the MTS T&S business, which was part of the recent MTS acquisition, has never been nor is expected to ever be considered part of our continuing operations, the Company classifies and reports the financial results and related cash flows of the MTS T&S business as discontinued operations, effective as of the MTS acquisition date, in the accompanying Condensed Consolidated Financial Statements. The Company will continue to report the MTS T&S business as a discontinued operation until the business is sold to ITW as currently anticipated. As discussed in Note 11 herein, the purchase price allocation associated with the MTS T&S business is being performed separately from the MTS Sensors business, as the MTS T&S business meets the “held for sale” accounting criteria. These assets acquired and liabilities assumed resulting from the MTS T&S purchase price allocation are measured and recorded at fair value less costs to sell as of the date of the MTS acquisition; such accounts are included in Current assets held for sale and Current liabilities held for sale, respectively, in the Condensed Consolidated Balance Sheets, each presented as separate single line items in the Condensed Consolidated Balance Sheets as of June 30, 2021. The Company expects to close on the sale of the MTS T&S business within one year of the date of the acquisition of MTS, and as such, these associated assets held for sale and liabilities held for sale have been classified as current as of June 30, 2021. The Company also ceased recording depreciation and amortization on the held for sale assets as of the MTS acquisition date.

​

The Company did not assign the MTS T&S business to either of our two reportable business segments due to its planned sale. Amphenol will not have any continuing involvement with the MTS T&S business after the date of its divestiture.

Other than goodwill noted above, the Company’s intangible assets as of June 30, 2021 and December 31, 2020 were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

The increase in the gross carrying amount of intangible assets in the first six months of 2021 was driven by certain customer relationships recognized as a result of the acquisition accounting associated with our 2021 acquisitions, primarily from the MTS acquisition. Amortization expense for the three months ended June 30, 2021 and 2020 was approximately $32.6 and $12.5, respectively. Amortization expense for the six months ended June 30, 2021 and 2020 was approximately $44.9 and $25.4, respectively. Amortization expense for the three and six months ended June 30, 2021 includes $16.2 related to the amortization of acquired backlog resulting from the MTS acquisition. As of June 30, 2021, amortization expense relating to the Company’s current intangible assets estimated for the remainder of 2021 is approximately $32.1 and for each of the next five fiscal years is approximately $57.5 in 2022, $54.7 in 2023, $48.9 in 2024, $39.5 in 2025 and $37.8 in 2026.

​

Note 14—Reportable Business Segments

​

The Company has two reportable business segments: (i) Interconnect Products and Assemblies and (ii) Cable Products and Solutions. The Company organizes its reportable business segments based upon similar economic characteristics and business groupings of products, services, and customers, and do not include any aggregated operating segments. These reportable business segments are determined based upon how the Company operates its businesses, assesses operating performance, makes resource allocation decisions, and communicates results, outlook and strategy to our Board of Directors and shareholders. The Interconnect Products and Assemblies segment primarily designs, manufactures and markets a broad range of connector and connector systems, value-add products and other products, including antennas and sensors, used in a broad range of applications in a diverse set of end markets. The Cable Products and Solutions segment primarily designs, manufactures and markets cable, value-add products and components for use primarily in the broadband communications and information technology markets as well as certain applications in other markets. The accounting policies of the segments are the same as those for the Company as a whole and are described herein and in Note 1 of the Notes to Consolidated Financial Statements in the 2020 Annual Report. The Company evaluates the performance of the segments and allocates resources to them based on, among other things, profit or loss from operations before interest, headquarters’ expense allocations, stock-based compensation expense, income taxes, amortization related to certain intangible assets and nonrecurring gains and losses.

Note 15—Revenue Recognition

​

Revenues consist of product sales to either end customers and their appointed contract manufacturers (including original equipment manufacturers) or to distributors, and the vast majority of our sales are recognized at a point-in-time under the core principle of recognizing revenue when control transfers to the customer. With limited exceptions, the Company recognizes revenue at the point in time when we ship or deliver the product from our manufacturing facility to our customer, when our customer accepts and has legal title of the goods, and where the Company has a present right to payment for such goods. For the three and six months ended June 30, 2021 and 2020, less than 5% of our net sales were recognized over time, where the associated contracts relate to the sale of goods with no alternative use as they are only sold to a single customer and whose underlying contract terms provide the Company with an enforceable right to payment, including a reasonable profit margin, for performance completed to date, in the event of customer termination. Since we typically invoice our customers at the same time that we satisfy our performance obligations, contract assets and contract liabilities related to our contracts with customers recorded in the Company’s Condensed Consolidated Balance Sheets were not significant as of June 30, 2021 and December 31, 2020. These amounts are recorded in the accompanying Condensed Consolidated Balance Sheets within Prepaid expenses and other current assets or Other accrued expenses as of June 30, 2021 and December 31, 2020.

​

The Company receives customer orders negotiated with multiple delivery dates that may extend across more than one reporting period until the contract is fulfilled, the end of the order period is reached, or a pre-determined maximum order value has been reached. Orders typically fluctuate from quarter to quarter based on customer demand and general business conditions. It is generally expected that a substantial portion of our remaining performance obligations will be fulfilled within three months, and nearly all of our performance obligations are fulfilled within one year. Since our performance obligations are part of contracts that generally have original durations of one year or less, we have not

24

Table of Contents

disclosed the aggregate amount of transaction prices associated with unsatisfied or partially unsatisfied performance obligations as of June 30, 2021.

​

While the Company typically offers standard product warranty coverage which provides assurance that our products will conform to the contractually agreed-upon specifications for a limited period from the date of shipment, the Company’s warranty liabilities as of June 30, 2021 and December 31, 2020, and related warranty expense for the three and six months ended June 30, 2021 and 2020, have not been and were not material in the accompanying Condensed Consolidated Financial Statements.

Note 16—Commitments and Contingencies

​

The Company has been named as a defendant in several legal actions arising from normal business activities. The Company records a loss contingency liability when a loss is considered probable and the amount can be reasonably estimated. Although the potential liability with respect to certain of such legal actions cannot be reasonably estimated, none of such matters is expected to have a material adverse effect on the Company’s financial condition, results of operations or cash flows. The Company’s legal costs associated with defending itself are recorded to expense as incurred.

In August 2018, the Company received a subpoena from the U.S. Department of Defense, Office of the Inspector General, requesting documents pertaining to certain products manufactured by the Company’s Military and Aerospace Group that are purchased or used by the U.S. government. This matter is ongoing and the Company is cooperating with the request. The Company is currently unable to estimate the timing or outcome of the matter.

​

From December 2019 through October 2020, the Company has been named as one of several defendants in four separate lawsuits filed in the State of Indiana. The lawsuits relate to a manufacturing site in Franklin, Indiana (the “Site”) where the Company has been conducting an environmental clean-up effort under the direction of the United States Environmental Protection Agency (the “EPA”). The Site was shut down in 1983, more than three years before the Company acquired the Site as part of a larger acquisition that led to the establishment of the Company’s business in 1987 (the “Acquisition”). In connection with the Acquisition, the Company agreed, and has continued, to work closely with the EPA regarding the ongoing clean-up effort at the Site, subject to an indemnity from the seller (the “Seller”). In 1989, the Company sold the property where the Site is located. The lawsuits collectively seek, among other things, compensation for personal injuries and for past, present and future medical expenses, compensation for loss of property values near the Site and costs related to medical monitoring for individuals living close to the Site, in each case arising from alleged exposure to hazardous chemicals. The Company denies any wrongdoing and is defending each of the above described lawsuits. All the costs incurred relating to these lawsuits are reimbursed by the Seller based on the Seller’s indemnification obligations entered into in connection with the Acquisition (the “1987 Indemnification Agreement”). In addition, the environmental investigation, remediation and monitoring activities undertaken by the Company relating to the Site are reimbursed under the 1987 Indemnification Agreement. As a result, the Company does not believe that the costs associated with these lawsuits or the resolution of the related environmental matters will have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

​

In March 2021, a non-material customer of the Company filed a formal request for arbitration against the Company relating to a product sold to such customer that the customer alleges did not meet the agreed upon product specification. The customer is pursuing breach of warranty claims against the Company, among other assertions, and is seeking damages relating to its estimated costs of replacing the product. While the customer has claimed damages of approximately €80, the arbitrator will have discretion to determine the actual amount of damages as well as the apportionment of responsibility between the parties. The Company has denied that its product caused the damages, that its product did not meet the agreed upon specifications and that the claimed damages are appropriate, and is vigorously defending itself in the arbitration.

​

Certain operations of the Company are subject to environmental laws and regulations that govern the discharge of pollutants into the air and water, as well as the handling and disposal of solid and hazardous wastes. The Company believes that its operations are currently in substantial compliance with applicable environmental laws and regulations and that the costs of continuing compliance will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

associated with adverse public health developments, including epidemics and pandemics such as the COVID-19 pandemic, which continues to disrupt our operations, including, depending on the specific location, government regulations that limit our ability to operate certain of our facilities at full capacity or at all and to adjust certain costs, travel restrictions, “work-from-home” orders, supplier constraints, supply-chain interruptions, logistics challenges and limitations, and reduced demand from certain customers; uncertainties associated with a protracted economic slowdown that could negatively affect the financial condition of our customers; uncertainties and volatility in the global capital markets; political, economic, military and other risks in countries outside the United States; the impact of general economic conditions, geopolitical conditions and U.S. trade policies, legislation, trade disputes, treaties and tariffs, including those affecting China, on the Company’s business operations; risks associated with the improper conduct by any of our employees, customers, suppliers, distributors or any other business partners which could impair our business reputation and financial results and could result in our non-compliance with anti-corruption laws and regulations of the U.S. government and various foreign jurisdictions; changes in exchange rates of the various currencies in which the Company conducts business; the Company’s ability to obtain a consistent supply of materials, at stable pricing levels; the Company’s dependence on sales to the communications industry, which markets are dominated by large manufacturers and operators who regularly exert significant pressure on suppliers, including the Company; changes in defense expenditures in the military market, including the impact of reductions or changes in the defense budgets of U.S. and foreign governments; the Company’s ability to compete successfully on the basis of technology innovation, product quality and performance, price, customer service and delivery time; the Company’s ability to continue to conceive, design, manufacture and market new products and ability to rely upon continuing market acceptance of its existing and future product lines; difficulties and unanticipated expenses in connection with purchasing and integrating newly acquired businesses, including the potential for the impairment of goodwill and other intangible assets; events beyond the Company’s control that could lead to an inability to meet its financial covenants, which could result in a default under the Company’s revolving credit facility; the Company’s ability to access the capital markets on favorable terms, including as a result of significant deterioration of general economic or capital market conditions, or as a result of a downgrade in the Company’s credit rating; changes in interest rates; government contracting risks that the Company may be subject to, including laws and regulations governing performance of U.S. government contracts and related risks associated with conducting business with the U.S. government or its suppliers (both directly and indirectly); governmental export and import controls that certain of our products may be subject to, including export licensing, customs regulations, economic sanctions or other laws; cybersecurity threats, malware, phishing, ransomware or other increasingly sophisticated attacks, that could impair our information technology systems and could disrupt business operations, result in a loss of or inability to access confidential information and critical business, financial or other data, and/or cause the release of highly sensitive confidential information and adversely impact our reputation and operating results and potentially lead to litigation and/or governmental investigations; changes in fiscal and tax policies, audits and examinations by taxing authorities, laws, regulations and guidance in the United States and foreign jurisdictions; any difficulties in protecting the Company’s intellectual property rights; and litigation, customer claims, product recalls, governmental investigations, criminal liability or environmental matters including changes to laws and regulations to which the Company may be subject. In addition, the extent to which the COVID-19 pandemic will continue to impact our business and financial results going forward will be dependent on future developments such as the length and severity of the crisis, any potential resurgence of the crisis including from the recent, more transmissible Delta variant strain, future government regulations and actions in response to the crisis, the timing, availability, effectiveness and adoption rates of vaccines, and the overall impact of the COVID-19 pandemic on the global economy and capital markets, among many other factors, all of which remain highly uncertain and unpredictable.

​

A further description of these uncertainties and other risks can be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, Quarterly Reports on Form 10-Q and the Company’s other reports filed with the Securities and Exchange Commission.

Impact of COVID-19 on our Operations, Financial Condition, Liquidity and Results of Operations

​

The COVID-19 pandemic caused widespread disruptions to our Company during 2020, particularly during the first half of that year, and as of June 30, 2021, we continue to experience some disruptions, and at a minimum, we expect those disruptions to continue through the third quarter of 2021 and they could, potentially, extend for the full year and

beyond. These disruptions have included and may continue to include, depending on the specific location, government regulations that limit our ability to operate certain of our facilities at full capacity or at all and to adjust certain costs, travel restrictions, “work-from-home” orders, supplier constraints, supply-chain interruptions, logistics challenges and limitations, and reduced demand from certain customers. In the second half of 2020 and into the first half of 2021, in several regions around the world, there was a resurgence in COVID-19 cases. The extent to which the COVID-19 pandemic will continue to impact our business and financial results going forward will be dependent on future developments such as the length and severity of the crisis, any potential resurgence of the crisis including from the recent, more transmissible Delta variant strain, future government regulations and actions in response to the crisis, the timing, availability, effectiveness and adoption rates of vaccines, and the overall impact of the COVID-19 pandemic on the global economy and capital markets, among many other factors, all of which remain highly uncertain and unpredictable. In addition, the COVID-19 pandemic could impact the health of our management team and other employees. The Company continues taking actions to mitigate, as best we can, the impact of the COVID-19 pandemic on the health and well-being of our employees, the communities in which we operate and our partners, as well as the impact on our operations and business as a whole. However, there can be no assurance that the COVID-19 pandemic will not have a material and adverse impact on our operations, financial condition, liquidity and results of operations.

Results of Operations

​

Three and six months ended June 30, 2021 compared to the three and six months ended June 30, 2020

​

Net sales were $2,653.9 in the second quarter of 2021 compared to $1,987.5 in the second quarter of 2020, which represented an increase of 34% in U.S. dollars, 30% in constant currencies and 22% organically, over the respective prior year period. Net sales were $5,031.0 in the first six months of 2021 compared to $3,849.5 in the first six months of 2020, which represented an increase of 31% in U.S. dollars, 27% in constant currencies and 22% organically, over the respective prior year period. The increase in net sales during the second quarter and first six months of 2021 was driven primarily by growth in several markets in the Interconnect Products and Assemblies segment, as described below.

​

Net sales in the Interconnect Products and Assemblies segment (approximately 96% of net sales) in the second quarter of 2021 increased 34% in U.S. dollars, 30% in constant currencies and 22% organically, compared to the second quarter of 2020. The increase in the second quarter of 2021 compared to the second quarter of 2020 was driven by growth in several markets, in particular by strong growth in the automotive, industrial, and military markets, and moderate growth in the information technology and data communications and commercial aerospace markets, which included contributions from the Company’s acquisition program, all of which were slightly offset by a moderate decline in the mobile devices market. Net sales in the Interconnect Products and Assemblies segment (approximately 96% of net sales) in the first six months of 2021 increased 31% in U.S. dollars, 27% in constant currencies and 22% organically, compared to the first six months of 2020. The increase in the first six months of 2021 compared to the first six months of 2020 was driven by growth in several markets, in particular by strong growth in the automotive, industrial, information technology and data communications, military and mobile devices markets, and moderate growth in the mobile networks market, along with contributions from the Company’s acquisition program, all of which were slightly offset by a significant decline in the commercial aerospace market which continued to be negatively impacted by the COVID-19 pandemic. The strong sales growth in 2021 in the Interconnect Products and Assemblies segment also reflected a recovery in certain markets from the negative impact resulting from the COVID-19 pandemic during both the second quarter and first six months of 2020.

​

Net sales in the Cable Products and Solutions segment (approximately 4% of net sales) in the second quarter of 2021, which primarily serves the broadband communications market, increased 27% in U.S. dollars, 24% in constant currencies and 15% organically, compared to the second quarter of 2020. Net sales in the Cable Products and Solutions segment (approximately 4% of net sales) in the first six months of 2021, which primarily serves the broadband communications market, increased 22% in U.S. dollars, 21% in constant currencies and 16% organically, compared to the first six months of 2020. The increase in both periods in 2021 was primarily driven by increased market demand at broadband operators, coupled with the market recovery from the negative impact of the COVID-19 pandemic that impacted the first six months of 2020 as well as the contribution from one acquisition in this segment that closed during the first quarter of 2021.

(1) | Net sales growth in U.S. dollars is calculated based on Net sales as reported in the Condensed Consolidated Statements of Income and Note 14 of the accompanying financial statements. While the term “net sales growth in U.S. dollars” is not considered a U.S. GAAP financial measure, for purposes of this table, we derive the reported (GAAP) measure based on GAAP results, which serves as the basis for the reconciliation to its comparable non-GAAP financial measures.

(2) | Foreign currency translation impact, a non-GAAP measure, represents the percentage impact on net sales resulting from foreign currency exchange rate changes in the current reporting period(s) compared to the same period(s) in the prior year. Such amount is calculated by subtracting current year net sales translated at average foreign currency exchange rates for the respective prior year period(s) from current year reported net sales, taken as a percentage of the respective prior period net sales.

(3) | Constant Currency Net Sales Growth and Organic Net Sales Growth are non-GAAP financial measures as defined in the "Non-GAAP Financial Measures" section.

(4) | Acquisition impact, a non-GAAP measure, represents the percentage impact on net sales resulting from acquisitions that have closed during the prior twelve months that have not been included in the Company's consolidated results for the full current period(s) and/or prior comparable period(s) presented. Such net sales related to these acquisitions do not reflect the underlying growth of the Company on a comparative basis.

​

Geographically, sales in the United States in the second quarter of 2021 increased 37% in U.S. dollars ($779.1 in 2021 versus $569.8 in 2020) and 24% organically, compared to the second quarter of 2020. Sales in the United States in the first six months of 2021 increased 23% in U.S. dollars ($1,453.0 in 2021 versus $1,185.2 in 2020) and 16% organically, compared to the first six months of 2020. Foreign sales in the second quarter of 2021 increased 32% in U.S. dollars ($1,874.8 in 2021 versus $1,417.7 in 2020), 27% in constant currencies and 21% organically, compared to the second quarter of 2020. Foreign sales in the first six months of 2021 increased approximately 34% in U.S. dollars ($3,578.0 in 2021 versus $2,664.3 in 2020), 30% in constant currencies and 25% organically, compared to the first six months of 2020. The comparatively weaker U.S. dollar for the second quarter and first six months of 2021 had the effect of increasing sales by approximately $74.0 and $130.5, respectively, relative to the comparable periods in 2020.

​

Selling, general and administrative expenses increased to $311.6, or 11.7% of net sales, and $574.3, or 11.4% of net sales, for the second quarter and first six months of 2021, respectively, compared to $246.4, or 12.4% of net sales, and $489.3, or 12.7% of net sales, for the second quarter and first six months of 2020, respectively. The decrease in selling, general and administrative expenses as a percentage of net sales in both the second quarter and first six months of 2021 is primarily driven by higher sales during both periods of 2021, relative to the comparable periods of 2020, slightly offset by the impact of the MTS Sensors business which currently has significantly higher selling, general and administrative expenses as a percentage of net sales compared to the average of the Company. Administrative expenses represented approximately 4.6% and 4.4% of net sales for the second quarter and first six months of 2021, respectively, and represented approximately 5.0% and 5.1% of net sales for the second quarter and first six months of 2020, respectively. Research and development expenses represented approximately 3.1% of net sales for both the second quarter and first six months of 2021, and represented approximately 3.1% of net sales for both the second quarter and first six months of 2020. Selling and marketing expenses represented approximately 4.1% and 3.9% of net sales for the second quarter and first six months of 2021, respectively, and represented approximately 4.3% and 4.5% of net sales for the second quarter and first six months of 2020, respectively.

​

Operating income was $476.2, or 17.9% of net sales, and $941.0, or 18.7% of net sales, for the second quarter and first six months of 2021, respectively, compared to $357.4, or 18.0% of net sales, and $674.3, or 17.5% of net sales, for

30

Table of Contents

the second quarter and first six months of 2020, respectively. Operating income for the second quarter and first six months of 2021 included $55.4 of acquisition-related expenses (separately presented in the Condensed Consolidated Statements of Income) primarily comprised of transaction, severance, restructuring and certain non-cash costs related to the acquisition of MTS Systems Corporation (“MTS”). For the three and six months ended June 30, 2021, these acquisition-related expenses had the effect of decreasing net income from continuing operations by $44.6, or $0.07 per share. Excluding the effect of these acquisition-related expenses, Adjusted Operating Income and Adjusted Operating Margin, as defined in the “Non-GAAP Financial Measures” section below, were $531.6, or 20.0% of net sales and $996.4, or 19.8% of net sales, for the three and six months ended June 30, 2021, respectively. The increase in Adjusted Operating Income and Adjusted Operating Margin for the second quarter and first six months of 2021 relative to the comparable period in 2020 was primarily driven by the Interconnect Products and Assemblies segment, as discussed further below.

​

Operating income for the Interconnect Products and Assemblies segment for the second quarter and first six months of 2021 was $559.7, or 22.0% of net sales, and $1,049.0, or 21.8% of net sales, respectively, compared to $379.5, or 20.0% of net sales, and $719.2, or 19.6% of net sales, for the second quarter and first six months of 2020, respectively. The increase in operating margin for the Interconnect Products and Assemblies segment for the second quarter and first six months of 2021 relative to the comparable periods in 2020 was primarily driven by normal operating leverage on the higher sales volumes combined with the benefit of a lower cost impact resulting from the COVID-19 pandemic compared to the second quarter and first six months of 2020, partially offset by the impact of the more challenging commodity and supply chain environment experienced to date in 2021.

​

Operating income for the Cable Products and Solutions segment for the second quarter and first six months of 2021 was $6.9, or 6.1% of net sales, and $15.4, or 7.4% of net sales, respectively, compared to $8.4, or 9.4% of net sales, and $14.8, or 8.6% of net sales, for the second quarter and first six months of 2020, respectively. The decrease in operating margin for the Cable Products and Solutions segment for the second quarter and first six months of 2021 relative to the comparable periods in 2020 is primarily driven by the impact of the more challenging commodity and supply chain environment experienced to date in 2021.

​

Interest expense for the second quarter and first six months of 2021 was $29.1 and $57.7, respectively, compared to $30.2 and $59.0 for the second quarter and first six months of 2020, respectively. Refer to Note 4 of the Condensed Consolidated Financial Statements for further information related to the Company’s debt.

​

Provision for income taxes for the second quarter and first six months of 2021 was at an effective tax rate of 17.5% and 20.6%, respectively. Provision for income taxes for the second quarter and first six months of 2020 was at an effective tax rate of 20.7% and 18.5%, respectively. For the second quarter and first six months of 2021 and 2020, the excess tax benefits resulting from stock option exercise activity had the impact of decreasing the effective tax rate and increasing earnings per share by the amounts noted in the tables below. For the second quarter and first six months of 2021, the effective tax rate was further impacted by the tax effect of acquisition-related expenses and the discrete tax benefit related to the settlement of uncertain tax positions in certain non-U.S. jurisdictions, each of which had the impact on the effective tax rate and earnings per share by the amounts noted in the tables below. For the first six months of 2020, the effective tax rate was also impacted by a discrete tax benefit related to the settlements of refund claims in a non-U.S. jurisdiction and the resulting adjustments to deferred taxes, which had the impact of decreasing the effective tax rate and increasing earnings per share by the amounts noted in the tables below. Excluding the effect of these items, the Adjusted Effective Tax Rate, a non-GAAP financial measure as defined in the “Non-GAAP Financial Measures” section below within this Item 2, for the three and six months ended June 30, 2021 and 2020 was 24.5% for all periods, as reconciled in the tables below to the comparable effective tax rate based on GAAP results. Refer to Note 6 of the Condensed Consolidated Financial Statements for further information related to income taxes.

​

Net income from continuing operations attributable to Amphenol Corporation and Net income (from continuing operations) per common share attributable to Amphenol Corporation - Diluted (“Diluted EPS”) were $367.2 and $0.59, respectively, for the second quarter of 2021, compared to $257.7 and $0.42, respectively, for the second quarter of 2020. Excluding the effect of the aforementioned items discussed above, Adjusted Net Income from continuing operations attributable to Amphenol Corporation and Adjusted Diluted EPS, non-GAAP financial measures as defined in the “Non-GAAP Financial Measures” section below within this Item 2, were $377.6 and $0.61, respectively, for the second

Table of Contents

quarter of 2021, compared to $245.3 and $0.40, respectively, for the second quarter of 2020. Net income from continuing operations attributable to Amphenol Corporation and Diluted EPS were $696.7 and $1.12, respectively, for the first six months of 2021, compared to $499.8 and $0.82, respectively, for the first six months of 2020. Excluding the effect of the aforementioned items discussed above, Adjusted Net Income from continuing operations attributable to Amphenol Corporation and Adjusted Diluted EPS were $704.4 and $1.13, respectively, for the first six months of 2021, compared to $462.5 and $0.76, respectively, for the first six months of 2020.

​

The following tables reconcile Adjusted Operating Income, Adjusted Operating Margin, Adjusted Net Income from continuing operations attributable to Amphenol Corporation, Adjusted Effective Tax Rate and Adjusted Diluted EPS (all on a continuing operations basis only, as defined in the “Non-GAAP Financial Measures” section below) to the most directly comparable U.S. GAAP financial measures for the three and six months ended June 30, 2021 and 2020:

(1) | While the terms “operating margin” and “effective tax rate” are not considered U.S. GAAP financial measures, for purposes of this table, we derive the reported (GAAP) measures based on GAAP results, which serve as the basis for the reconciliation to their comparable non-GAAP financial measure.

(2) | All percentages and per share amounts in this table were calculated using actual, unrounded results; therefore, the sum of the components may not add due to rounding.

​

Discontinued Operations

​

Following the acquisition of MTS, the Company concluded that the MTS T&S business met the discontinued operations reporting criteria as of the MTS acquisition date of April 7, 2021 in light of our definitive agreement to sell the MTS T&S business to ITW. As a result, the financial results of the MTS T&S business are reported as discontinued operations for the three and six months ended June 30, 2021. Income from discontinued operations attributable to Amphenol Corporation, net of income taxes, was $2.6 for both the second quarter and first six months of 2021. Income from discontinued operations relates to the results associated with the MTS T&S business that was acquired as part of the MTS acquisition. The Company will continue to account for the MTS T&S business as discontinued operations until the business is sold to ITW upon the receipt of all required regulatory approvals and the satisfaction of other customary closing conditions, which we expect to occur within one year of the date of the acquisition of MTS. The Company expects to incur certain transaction fees and other professional and external costs associated with the planned sale of the

MTS T&S business. Refer to Note 12 of the Notes to Condensed Consolidated Financial Statements for further details related to the planned divestiture of the MTS T&S business.

​

Liquidity and Capital Resources

​

As of June 30, 2021 and December 31, 2020, the Company had cash, cash equivalents and short-term investments of $1,242.6 and $1,738.1, respectively, with the majority of such funds located outside of the United States. On April 7, 2021, the Company used a combination of cash and cash equivalents on hand and borrowings under its U.S. Commercial Paper Program (defined below) to fund the acquisition of MTS.

​

As a result of the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”), on December 31, 2017, the Company indicated an intention to repatriate most of its pre-2018 accumulated earnings and recorded the foreign and U.S. state and local tax costs related to the repatriation. The associated tax payments are due as the repatriations are made. The Company intends to distribute certain post-2017 foreign earnings and has accrued foreign and U.S. state and local taxes, if applicable, on those earnings as appropriate as of June 30, 2021, and intends to indefinitely reinvest all remaining post-2017 foreign earnings. The Company intends to evaluate future earnings for distribution, and accrue for those distributions where appropriate, and to indefinitely reinvest all other foreign earnings. In addition, the Transition Tax on the deemed repatriation of the accumulated unremitted earnings and profits of foreign subsidiaries will be paid, net of applicable tax credits and deductions, in annual installments until 2025, as permitted under the Tax Act.

​

The Company’s primary sources of liquidity are internally generated cash flow, our cash, cash equivalents and short-term investments on hand, the Commercial Paper Programs and the Revolving Credit Facility (each as defined and discussed further within this Item 2). The Company believes that its cash, cash equivalents and short-term investment position on hand, ability to generate future cash flow from operations, availability under its credit facilities, and access to capital markets, including recent borrowings under the U.S. Commercial Paper Program to partially fund the acquisition of MTS, provide adequate liquidity to meet its obligations for at least the next twelve months.

​

The Company’s primary ongoing cash requirements will be for operating and capital expenditures, product development activities, repurchases of its Common Stock, dividends, debt service, payments associated with the Transition Tax (which is payable in annual installments until 2025), taxes due upon the repatriation of foreign earnings (which will be payable upon the repatriation of such earnings), and funding of pension obligations. The Company’s debt service requirements consist primarily of principal and interest on the Company’s Senior Notes, and to the extent of any amounts outstanding, the Revolving Credit Facility and the Commercial Paper Programs (all as defined below). The Company may also use cash to fund all or part of the cost of acquisitions, as was the case with the recent acquisition of MTS.

​

Cash Flow Summary

​

The following table summarizes the Company’s cash flows from operating, investing and financing activities for the six months ended June 30, 2021 and 2020, as reflected in the Condensed Consolidated Statements of Cash Flow:

Operating Activities

​

The ability to generate cash from operating activities is one of the Company’s fundamental financial strengths. Net cash provided by operating activities from continuing operations (“Operating Cash Flow”) was $732.0 in the first six months of 2021 compared to $752.4 in the first six months of 2020. The decrease in Operating Cash Flow for the first six months of 2021 compared to the first six months of 2020 is primarily due to a higher usage of cash related to the change in working capital, partially offset by an increase in net income from continuing operations.

​

In the first six months of 2021, the components of working capital as presented on the accompanying Condensed Consolidated Statements of Cash Flow increased $194.9, excluding the impact of acquisitions and foreign currency translation, primarily due to increases in inventories of $165.4, accounts receivable of $42.4 and prepaid expenses and other current assets of $15.0 and a decrease in accrued liabilities, including income taxes, of $24.6, partially offset by an increase in accounts payable of $52.5. In the first six months of 2020, the components of working capital as presented on the accompanying Condensed Consolidated Statements of Cash Flow decreased $70.8, excluding the impact of acquisitions and foreign currency translation, primarily due to increases in accounts payable of $72.3 and accrued liabilities, including income taxes, of $34.8, along with a decrease in accounts receivable of $54.8, partially offset by increases in inventories of $69.3 and prepaid expenses and other current assets of $21.8.

​

The following describes the significant changes in the amounts as presented on the accompanying Condensed Consolidated Balance Sheets at June 30, 2021 as compared to December 31, 2020. Accounts receivable increased $121.2 to $2,072.8, primarily due to higher sales in the second quarter of 2021 relative to the fourth quarter of 2020, along with the impact of the MTS acquisition and the other five acquisitions (collectively, the “2021 acquisitions”) that closed during the first six months of 2021, partially offset by the effect of translation from exchange rate changes (“Translation”) at June 30, 2021 compared to December 31, 2020. Days sales outstanding at June 30, 2021 and December 31, 2020 were 71 days and 72 days, respectively. Inventories increased $309.2 to $1,771.4, primarily due to higher sales in addition to the impact of recent supply chain disruptions experienced during the first six months of 2021, along with the impact of the 2021 acquisitions, partially offset by Translation. Inventory days at June 30, 2021 and December 31, 2020 were 85 days and 79 days, respectively. Prepaid expenses and other current assets increased $33.1 to $372.0, primarily due to increases in certain prepaid expenses and other current receivables as well as the impact of the 2021 acquisitions. Property, plant and equipment, net, increased $114.7 to $1,169.3, primarily due to capital expenditures of $183.3 and the impact of the 2021 acquisitions, partially offset by depreciation of $131.6 and Translation. Goodwill increased $859.6 to $5,891.7, resulting from goodwill recognized related to the 2021 acquisitions, primarily from the MTS acquisition, partially offset by Translation. Other intangible assets, net increased $223.3 to $620.8, primarily due to the recognition of certain intangible assets related to the 2021 acquisitions, primarily from the MTS acquisition, partially offset by amortization. Other long-term assets increased $33.8 to $386.1, primarily due to an increase in operating lease right-of-use assets resulting from both leases assumed from the 2021 acquisitions as well as new and renewed lease agreements entered into during the first six months of 2021. Accounts payable increased $84.0 to $1,204.7, primarily due to increased purchasing activity related to higher sales levels, along with the impact of the 2021 acquisitions. Payable days at June 30, 2021 and December 31, 2020 were 60 days and 61 days, respectively. Total accrued expenses, including accrued income taxes, increased $88.8 to $1,042.1, primarily as a result of the MTS acquisition and the other 2021 acquisitions, along with an increase in accrued salaries and wages and other accrued expenses, partially offset by a decrease in accrued income taxes, primarily resulting from certain tax payments. Other long-term liabilities, including deferred tax liabilities, increased $140.7 to $847.0, primarily as a result of an increase in deferred tax liabilities resulting from the MTS acquisition.

​

There is no current requirement for cash contributions to any of the Company’s defined benefit pension plans in the U.S., and the Company plans to evaluate annually, based on actuarial calculations and the investment performance of the pension plans’ assets, the timing and amount of cash contributions in the future, as discussed in more detail in Note 10 of the Notes to Condensed Consolidated Financial Statements.

​

In addition to cash flow from operating activities, the Company also considers Free Cash Flow, a non-GAAP financial measure defined in the “Non-GAAP Financial Measures” section below, as a key metric in measuring the Company’s ability to generate cash. The following table reconciles Free Cash Flow to its most directly comparable U.S. GAAP financial measure for the six months ended June 30, 2021 and 2020. The decrease in Free Cash Flow was

34

Table of Contents

primarily driven by an increase in capital expenditures, and to a lesser extent, the decrease in Operating Cash Flow, as described above. The following table is on a continuing operations basis only and excludes any cash flows related to discontinued operations:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Six Months Ended June 30,
​ |  | 2021 |  | 2020
Operating Cash Flow (GAAP) |  | $ | 732.0 |  | $ | 752.4
Capital expenditures (GAAP) | ​ | ​ | (183.3) | ​ | ​ | (128.3)
Proceeds from disposals of property, plant and equipment (GAAP) | ​ |  | 1.6 | ​ |  | 1.9
Free Cash Flow (non-GAAP) | ​ | $ | 550.3 | ​ | $ | 626.0

​

Investing Activities

​

Cash flows from investing activities consist primarily of cash flows associated with capital expenditures, proceeds from disposals of property, plant and equipment, net sales and maturities (purchases) of short-term investments, and acquisitions.

​

Net cash used in investing activities from continuing operations was $1,721.3 in the first six months of 2021, compared to $151.7 in the first six months of 2020. In the first six months of 2021, net cash used in investing activities from continuing operations was driven primarily by the use of $1,531.0 to fund acquisitions and capital expenditures (net of disposals) of $181.7, partially offset by net sales and maturities of short-term investments of $2.6. In the first six months of 2020, net cash used in investing activities was driven primarily by capital expenditures (net of disposals) of $126.4, the use of $16.5 to fund acquisitions, and net purchases of short-term investments of $8.8.

​

Financing Activities

​

Cash flows from financing activities consist primarily of cash flows associated with borrowings and repayments of the Company’s credit facilities and other long-term debt, repurchases of common stock, proceeds from stock option exercises, dividend payments, and distributions to and purchases of noncontrolling interests.

​

Net cash provided by financing activities from continuing operations was $613.0 in the first six months of 2021, compared to net cash used in financing activities from continuing operations of $191.4 in the first six months of 2020. For the first six months of 2021, net cash provided by financing activities from continuing operations was driven primarily by (i) net borrowings of $1,402.7 comprised primarily of borrowings under the U.S. Commercial Paper Program, most of the proceeds of which were used for the MTS acquisition and (ii) cash proceeds of $103.3 from the exercise of stock options, partially offset by (i) debt repayments of $387.1, primarily related to the repayment of the then-outstanding MTS senior notes, (ii) repurchases of the Company’s common stock of $320.1, (iii) dividend payments of $173.4, (iv) distributions to and purchases of noncontrolling interests of $8.3, and (v) payments of $4.1 associated with the deferred purchase price related to acquisitions. For the first six months of 2020, net cash used in financing activities was driven primarily by (i) the repayment of the Company’s 2.20% U.S. Senior Notes due April 2020 and other debt of $401.3, (ii) net repayments related to the Company’s commercial paper programs of $385.2, (iii) repurchases of the Company’s common stock of $257.2, (iv) dividend payments of $148.4, (v) payment related to acquisition-related contingent consideration of $75.0, (vi) distributions to and purchases of noncontrolling interests of $9.7, (vii) payments of costs of $8.7 related to debt financing primarily associated with the 2025 Senior Notes and 2026 Euro Notes (each as defined below), and (viii) net repayments under the Company’s credit facilities of $0.7, partially offset by the (i) net cash proceeds from both the February 2020 issuance of the 2025 Senior Notes and the May 2020 issuance of the 2026 Euro Notes of $942.3 and (ii) cash proceeds of $152.5 from the exercise of stock options.

​

The Company has significant flexibility to meet its financial commitments. The Company uses debt financing to lower the overall cost of capital and increase return on stockholders’ equity. The Company’s debt financing includes the use of commercial paper programs, the Revolving Credit Facility and senior notes as part of its overall cash management strategy.

​

Table of Contents

The Company has a $2,500.0 unsecured credit facility (the “Revolving Credit Facility”), which matures January 2024 and gives the Company the ability to borrow, in various currencies, at a spread over LIBOR. The Company may utilize the Revolving Credit Facility for general corporate purposes. As of June 30, 2021 and December 31, 2020, there were no outstanding borrowings under the Revolving Credit Facility. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants. At June 30, 2021, the Company was in compliance with the financial covenants under the Revolving Credit Facility.

​

Pursuant to the terms of the U.S. commercial paper program, the Company may issue short-term unsecured commercial paper notes (the “USCP Notes”) in one or more private placements in the United States (the “U.S. Commercial Paper Program”). The maximum aggregate principal amount outstanding of USCP Notes at any time is $2,500.0. The amount of USCP Notes outstanding as of June 30, 2021 was $1,401.0, with a weighted average interest rate of 0.21%. On April 7, 2021, a combination of borrowings under the U.S. Commercial Paper Program and cash and cash equivalents on hand were used to fund the acquisition of MTS Systems Corporation. As of December 31, 2020, there were no USCP Notes outstanding.

​

The Company and one of its wholly owned European subsidiaries (collectively, the “Euro Issuer”) also has a commercial paper program (the “Euro Commercial Paper Program” and, together with the U.S. Commercial Paper Program, the “Commercial Paper Programs”) pursuant to which the Euro Issuer may issue short-term unsecured commercial paper notes (the “ECP Notes” and, together with the USCP Notes, “Commercial Paper”), which are guaranteed by the Company and are to be issued outside of the United States. The ECP Notes may be issued in Euros, Sterling, U.S. dollars or other currencies. The maximum aggregate principal amount outstanding of ECP Notes at any time is $2,000.0. As of June 30, 2021 and December 31, 2020, there were no ECP Notes outstanding.

​

Amounts available under the Commercial Paper Programs may be borrowed, repaid and re-borrowed from time to time. In conjunction with the Revolving Credit Facility, the authorization from the Company’s Board of Directors limits the maximum principal amount outstanding of USCP Notes, ECP Notes, and any other commercial paper or similar programs, along with outstanding amounts under the Revolving Credit Facility, at any time to $2,500.0 in the aggregate. The Commercial Paper Programs are rated A-2 by Standard & Poor’s and P-2 by Moody’s and are currently backstopped by the Revolving Credit Facility, as amounts undrawn under the Company’s Revolving Credit Facility are available to repay Commercial Paper, if necessary. Net proceeds of the issuances of Commercial Paper are expected to be used for general corporate purposes. The Company reviews its optimal mix of short-term and long-term debt regularly and may replace certain amounts of Commercial Paper, short-term debt and current maturities of long-term debt with new issuances of long-term debt in the future.

​

As of June 30, 2021, the Company has outstanding senior notes (the “Senior Notes”) as follows:

Senior Notes is payable semiannually. The Company may, at its option, redeem some or all of any series of U.S. Senior Notes, subject to certain terms and conditions. The remaining principal amounts outstanding associated with the Company’s 3.125% Senior Notes due in September 2021 and 4.00% Senior Notes due in February 2022 are each recorded, net of the related unamortized discount and debt issuance costs, within Current portion of long-term debt in the accompanying Condensed Consolidated Balance Sheets as of June 30, 2021.

​

On May 4, 2020, the Euro Issuer issued €500.0 (approximately $545.4 at date of issuance) principal amount of unsecured 0.750% Senior Notes due May 4, 2026 at 99.563% of face value (the “2026 Euro Notes” or the “0.750% Euro Senior Notes” and collectively with the Euro Notes due October 2028, the “Euro Notes”). The Company used the net proceeds from the 2026 Euro Notes to repay amounts outstanding under the Revolving Credit Facility.

​

The Euro Notes are unsecured and rank equally in right of payment with the Euro Issuer’s other unsecured senior indebtedness, and are fully and unconditionally guaranteed on a senior unsecured basis by the Company. Interest on each series of the Euro Notes is payable annually. The Company may, at its option, redeem some or all of any series of Euro Notes, subject to certain terms and conditions.

​

The Company’s Senior Notes contain certain financial and non-financial covenants. Refer to Note 4 of the Condensed Consolidated Financial Statements for further information related to the Company’s debt.

​

In April 2018, the Company’s Board of Directors authorized a stock repurchase program under which the Company could purchase up to $2,000.0 of the Company’s Common Stock during the three-year period ending April 24, 2021 (the “2018 Stock Repurchase Program”) in accordance with the requirements of Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). During the three and six months ended June 30, 2021, the Company repurchased 0.8 million and 3.1 million shares of its Common Stock for $51.0 and $203.8, respectively, under the 2018 Stock Repurchase Program. As a result of these purchases, the Company completed all purchases authorized under the 2018 Stock Repurchase Program and, therefore, the 2018 Stock Repurchase Program has terminated. Of the total repurchases made during the first six months of 2021, 0.3 million shares, or $19.8, have been retained in Treasury stock at the time of repurchase; the remaining 2.8 million shares, or $184.0, have been retired by the Company. The Company did not repurchase any of its Common Stock during the three months ended June 30, 2020, while during the six months ended June 30, 2020, the Company repurchased 5.4 million shares of its Common Stock for $257.2 under the 2018 Stock Repurchase Program. All of the shares repurchased during the first six months of 2020 were retired by the Company.

​

On April 27, 2021, the Company’s Board of Directors authorized a new stock repurchase program under which the Company may purchase up to $2,000.0 of the Company’s Common Stock during the three-year period ending April 27, 2024 (the “2021 Stock Repurchase Program”) in accordance with the requirements of Rule 10b-18 of the Exchange Act. During the three months ended June 30, 2021, the Company repurchased 1.7 million shares of its Common Stock for $116.3 under the 2021 Stock Repurchase Program. All of the shares repurchased under the 2021 Stock Repurchase Program during the second quarter of 2021 have been or will be retired by the Company. From July 1, 2021 to July 27, 2021, the Company repurchased 0.7 million additional shares of its Common Stock for $48.8 under the 2021 Stock Repurchase Program, and has remaining authorization to purchase up to $1,834.9 of its Common Stock under the 2021 Stock Repurchase Program. The price and timing of any future purchases under the 2021 Stock Repurchase Program will depend on a number of factors such as levels of cash generation from operations, the volume of stock option exercises by employees, cash requirements for acquisitions, dividends paid, economic and market conditions and the price of the Company’s common stock.

​

Acquisitions and Divestitures

​

During the first six months of 2021, the Company completed six acquisitions, all but one of which is included within the Interconnect Products and Assemblies segment, for approximately $1,531.0, net of cash acquired. These 2021 acquisitions were not material, either individually or in the aggregate, to the Company.

​

Acquisition of MTS and Planned Divestiture of MTS T&S Business

​

On April 7, 2021, pursuant to a definitive agreement dated December 9, 2020, by and among the Company and MTS, the Company completed the acquisition of MTS for a purchase price of approximately $1,300, net of cash acquired and including the repayment of certain outstanding debt and liabilities at closing. The MTS acquisition was funded through a combination of borrowings under the U.S. Commercial Paper Program and cash and cash equivalents on hand. In addition to the purchase price, the Company also assumed MTS’s then-outstanding $350.0 principal amount of senior notes due August 15, 2027, which the Company repaid and settled shortly after the closing for approximately $387.3, which included accrued interest and a make-whole premium incurred as a result of the early extinguishment of the senior notes. MTS is a leading global supplier of precision sensors, advanced test systems and motion simulators. MTS was historically organized into two business segments: Sensors (“MTS Sensors”) and Test & Simulation (“MTS T&S”). The MTS Sensors segment represents a highly complementary offering of high-technology, harsh environment sensors sold into diverse end markets and applications. The MTS Sensors business further expands the Company’s range of sensor and sensor-based products across a wide array of industries and is reported as part of our continuing operations and within our Interconnect Products and Assemblies segment. In the second quarter of 2021, the Company incurred $55.4 ($44.6 after-tax, or $0.07 per diluted share) of acquisition-related expenses, primarily comprised of transaction, severance, restructuring and certain non-cash costs related to the MTS acquisition.

​

On January 19, 2021 and prior to the closing of the MTS acquisition, the Company entered into a definitive agreement to sell the MTS T&S business to Illinois Tool Works Inc. (“ITW”). The agreed-upon sale price is approximately $750, subject to certain post-closing adjustments and excluding any outstanding net debt assumed by Amphenol related to the MTS T&S business. The Company expects to close on the sale of the MTS T&S business upon the receipt of all required regulatory approvals and the satisfaction of other customary closing conditions, which is expected to be within one year of the date of the acquisition of MTS. The MTS T&S business meets the “held for sale” accounting criteria, and its results and related cash flows are reported as discontinued operations, effective as of the MTS acquisition date, in the accompanying Condensed Consolidated Financial Statements. Such classification as discontinued operations will continue until the MTS T&S business is sold to ITW as currently anticipated. The Company did not assign the MTS T&S business to either of our two reportable business segments due to its planned sale. Amphenol will not have any continuing involvement with the MTS T&S business after the date of its divestiture.

well as the planned divestiture of the MTS T&S business, refer to Note 12 of the Notes to Condensed Consolidated Financial Statements.

​

Environmental Matters

​

Certain operations of the Company are subject to environmental laws and regulations that govern the discharge of pollutants into the air and water, as well as the handling and disposal of solid and hazardous wastes. The Company believes that its operations are currently in substantial compliance with applicable environmental laws and regulations and that the costs of continuing compliance will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows. For more information on certain environmental matters, refer to Note 16 of the Notes to Condensed Consolidated Financial Statements.

​

Non-GAAP Financial Measures

​

In addition to assessing the Company’s financial condition, results of operations, liquidity and cash flows in accordance with U.S. GAAP, management utilizes certain non-GAAP financial measures defined below as part of its internal reviews for purposes of monitoring, evaluating and forecasting the Company’s financial performance, communicating operating results to the Company’s Board of Directors and assessing related employee compensation measures. Management believes that these non-GAAP financial measures may be helpful to investors in assessing the Company’s overall financial performance, trends and period-over-period comparative results, in addition to the reasons noted below. Non-GAAP financial measures related to operating income, operating margin, net income from continuing operations attributable to Amphenol Corporation, effective tax rate and diluted EPS from continuing operations exclude income and expenses that are not directly related to the Company’s operating performance during the periods presented. Items excluded in the presentation of such non-GAAP financial measures in any period may consist of, without limitation, acquisition-related expenses, refinancing-related costs, and certain discrete tax items including but not limited to (i) the excess tax benefits related to stock-based compensation and (ii) the impact of significant changes in tax law. Non-GAAP financial measures related to net sales exclude the impact of foreign currency exchange rates and acquisitions. Non-GAAP financial measures and their most directly comparable U.S. GAAP financial measures presented within this Item 2 are on a continuing operations basis only and exclude any results associated with discontinued operations. The non-GAAP financial information contained herein is included for supplemental purposes only and should not be considered in isolation, as a substitute for or superior to the related U.S. GAAP financial measures. In addition, these non-GAAP financial measures are not necessarily the same or comparable to similar measures presented by other companies, as such measures may be calculated differently or may exclude different items.

​

The non-GAAP financial measures defined below should be read in conjunction with the Company’s financial statements presented in accordance with U.S. GAAP. The reconciliations of these non-GAAP financial measures to the most directly comparable U.S. GAAP financial measures for the three and six months ended June 30, 2021 and 2020 are included in “Results of Operations” and “Liquidity and Capital Resources” within this Item 2:

​

| ● | Adjusted Diluted EPS is defined as diluted earnings per share from continuing operations (as reported in accordance with U.S. GAAP), excluding income and expenses and their specific tax effects that are not directly related to the Company’s operating performance during the periods presented. Adjusted Diluted EPS is calculated as Adjusted Net Income from continuing operations attributable to Amphenol Corporation, as defined below, divided by the weighted average outstanding diluted shares as reported in the Condensed Consolidated Statements of Income.

​

| ● | Adjusted Effective Tax Rate is defined as Provision for income taxes, as reported in the Condensed Consolidated Statements of Income, expressed as a percentage of Income from continuing operations before income taxes, as reported in the Condensed Consolidated Statements of Income, each excluding the income and expenses and their specific tax effects that are not directly related to the Company’s operating performance during the periods presented.

​

| ● | Adjusted Net Income from continuing operations attributable to Amphenol Corporation is defined as Net income from continuing operations attributable to Amphenol Corporation, as reported in the Condensed Consolidated

39

Table of Contents

|  | Statements of Income, excluding income and expenses and their specific tax effects that are not directly related to the Company’s operating performance during the periods presented.

​

| ● | Adjusted Operating Income is defined as Operating income, as reported in the Condensed Consolidated Statements of Income, excluding income and expenses that are not directly related to the Company’s operating performance during the periods presented.

​

| ● | Adjusted Operating Margin is defined as Adjusted Operating Income (as defined above) expressed as a percentage of Net sales (as reported in the Condensed Consolidated Statements of Income).

​

| ● | Constant Currency Net Sales Growth is defined as the period-over-period percentage change in net sales growth, excluding the impact of changes in foreign currency exchange rates. The Company’s results are subject to volatility related to foreign currency translation fluctuations. As such, management evaluates the Company’s sales performance based on actual sales growth in U.S. dollars, as well as Organic Net Sales Growth (defined below) and Constant Currency Net Sales Growth, and believes that such information is useful to investors to assess the underlying sales trends.

​

| ● | Free Cash Flow is defined as (i) Net cash provided by operating activities from continuing operations (“Operating Cash Flow” - as reported in accordance with U.S. GAAP) less (ii) capital expenditures (as reported in accordance with U.S. GAAP), net of proceeds from disposals of property, plant and equipment (as reported in accordance with U.S. GAAP), all of which are derived from the Condensed Consolidated Statements of Cash Flow. Free Cash Flow is an important liquidity measure for the Company, as we believe it is useful for management and investors to assess our ability to generate cash, as well as to assess how much cash can be used to reinvest in the growth of the Company or to return to shareholders through either stock repurchases or dividends.

​

| ● | Organic Net Sales Growth is defined as the period-over-period percentage change in net sales growth resulting from operating volume and pricing changes, and excludes the impact of (i) changes in foreign currency exchange rates (described above), which is outside the control of the Company, and (ii) acquisitions, both of which are taken as a percentage of the respective prior period(s) net sales. The acquisition impact represents the percentage impact on net sales resulting from acquisitions that have closed during the prior twelve months that have not been included in the Company's consolidated results for the full current period(s) and/or prior comparable period(s) presented. Such net sales related to these acquisitions do not reflect the underlying growth of the Company on a comparative basis. Management evaluates the Company’s sales performance based on actual sales growth in U.S. dollars, as well as Constant Currency Net Sales Growth (defined above) and Organic Net Sales Growth, and believes that such information is useful to investors to assess the underlying sales trends.

Critical Accounting Policies and Estimates

​

The Company’s disclosures of its critical accounting policies, which are contained in its 2020 Annual Report, have not materially changed since that report was filed.

​

Item 3. Quantitative and Qualitative Disclosures About Market Risk

​

The Company, in the normal course of doing business, is exposed to a variety of risks, including market risks associated with foreign currency exchange rates and changes in interest rates. The Company does not have any significant concentration with any one counterparty. There has been no material change in the Company’s assessment of its sensitivity to foreign currency exchange rate risk since its presentation set forth in Part II, Item 7A “Quantitative and Qualitative Disclosures About Market Risk” in its 2020 Annual Report. From time to time, the Company may borrow under the Revolving Credit Facility and Commercial Paper Programs. Any borrowings under the Euro Commercial Paper Program and Revolving Credit Facility, in addition to the outstanding borrowings under the Company’s 2026 Euro Notes and 2028 Euro Notes, as discussed in Note 4 of the accompanying Condensed Consolidated Financial Statements, are and may continue to be denominated in foreign currencies, and there can be no assurance that the Company can successfully manage these changes in exchange rates, including in the event of a significant and sudden decline in the

40

Table of Contents

value of any of the foreign currencies for which such borrowings are made. In addition, any borrowings under the Revolving Credit Facility either bear interest at or trade at rates that fluctuate with a spread over LIBOR, while any borrowings under the Commercial Paper Programs are subject to floating interest rates. Therefore, when the Company borrows under these debt instruments, the Company is exposed to market risk from exposure to changes in interest rates. As of June 30, 2021, outstanding borrowings under the U.S. Commercial Paper Program were at a weighted average floating interest rate of 0.21%, while there were no outstanding borrowings under the Revolving Credit Facility and Euro Commercial Paper Program. The Company does not expect changes in interest rates to have a material effect on income or cash flows in 2021, although there can be no assurances that interest rates will not change significantly.

​

Item 4. Controls and Procedures

​

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures, pursuant to Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this report. These controls and procedures are designed to provide reasonable assurance that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on their evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

​

Changes in Internal Control Over Financial Reporting

​

There has been no change in our internal control over financial reporting during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

​

Repurchase of Equity Securities

​

In April 2018, the Company’s Board of Directors authorized a stock repurchase program under which the Company could purchase up to $2.0 billion of the Company’s Common Stock during the three-year period ending April 24, 2021 (the “2018 Stock Repurchase Program”) in accordance with the requirements of Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In April 2021, the Company repurchased 0.8 million shares of its Common Stock for $51.0 million. As a result of these purchases, the Company completed all purchases authorized under the 2018 Stock Repurchase Program and, therefore, the 2018 Stock Repurchase Program has terminated. All of the shares repurchased in April 2021 under the 2018 Stock Repurchase Program have been retired by the Company.

​

On April 27, 2021, the Company’s Board of Directors authorized a new stock repurchase program under which the Company may purchase up to $2.0 billion of the Company’s Common Stock during the three-year period ending April 27, 2024 (the “2021 Stock Repurchase Program”) in accordance with the requirements of Rule 10b-18 of the Exchange Act. During the three months ended June 30, 2021, the Company repurchased 1.7 million shares of its Common Stock for $116.3 million under the 2021 Stock Repurchase Program. All of the shares repurchased under the 2021 Stock Repurchase Program during the second quarter of 2021 have been or will be retired by the Company. From July 1, 2021 to July 27, 2021, the Company repurchased 0.7 million additional shares of its Common Stock for $48.8 million under the 2021 Stock Repurchase Program, and has remaining authorization to purchase up to $1,834.9 million of its Common Stock under the 2021 Stock Repurchase Program. The price and timing of any future purchases under the 2021 Stock Repurchase Program will depend on a number of factors such as levels of cash generation from operations, the volume of stock option exercises by employees, cash requirements for acquisitions, dividends paid, economic and market conditions and the price of the Company’s common stock.

​

The table below reflects the Company’s stock repurchases for the three months ended June 30, 2021:
