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 nine months ended September 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 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 September 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 nine months ended September 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.
