Acquisitions	Note 11—Acquisitions 2021 Acquisitions During the year ended December 31, 2021, the Company completed seven acquisitions for $2,225.4, net of cash acquired, while also completing the divestiture of the Divested MTS business, as discussed below and in Note 12 herein. Six of the acquisitions were included in the Interconnect Products and Assemblies segment, while one acquisition was 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 Consolidated Statements of Income for the year ended December 31, 2021, 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. Prior to the acquisition, MTS was 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 business provides the Company with 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 MTS (including the MTS T&S business, but excluding the MTS Sensors business) to Illinois Tool Works Inc. (“ITW”). Throughout this Annual Report, we refer to MTS (including the MTS T&S business, but excluding the MTS Sensors business) as the “Divested MTS business”. On April 7, 2021, the Company completed the acquisition of MTS for a total enterprise value of approximately $1,700, net of cash acquired and including the repayment of all outstanding debt and certain liabilities. 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 on hand. At closing, the Company paid approximately $1,300, net of cash acquired, for 100% of the common stock of MTS, including certain liabilities settled at closing, which is reflected within Net cash used in investing activities from continuing operations in the accompanying Consolidated Statements of Cash Flow for the year ended December 31, 2021. In addition, the Company also assumed MTS’s then-outstanding $350.0 principal amount of senior notes due August 15, 2027. Shortly after the closing, the Company repaid and settled the MTS senior notes 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 repayment of the outstanding senior notes, including the make-whole premium and excluding interest, was reflected within Net cash used in financing activities from continuing operations in the accompanying Consolidated Statements of Cash Flow for the year ended December 31, 2021. On December 1, 2021, the Company completed the sale of the Divested MTS business to ITW for approximately $750, net of cash divested and excluding related transaction fees and expenses. After giving effect to the sale of the Divested MTS business as well as the repayment of the aforementioned MTS senior notes as part of the MTS acquisition, the Company paid approximately $950, net of cash acquired and excluding related transaction fees and expenses, for the retained MTS Sensors business. Refer to Note 12 herein for further details related to the Company’s discontinued operations and the completed divestiture of the Divested MTS business. The Company is in the process of completing the acquisition accounting related to the MTS Sensors business, specifically the allocation of the purchase price attributable to the MTS Sensors business to the tangible and identifiable intangible assets acquired and liabilities assumed based upon their estimated fair values. The preliminary purchase price allocation for the MTS Sensors business is being performed separately from the Divested MTS business, the latter of which was accounted for as discontinued operations and whose assets acquired, including associated goodwill, and liabilities assumed were reported as current assets held for sale and liabilities held for sale in the Company’s balance sheet. As a result of the sale of the Divested MTS business on December 1, 2021, the Company completed the acquisition accounting associated with the Divested MTS business and the associated current assets held for sale and current liabilities held for sale are no longer reported on the Company’s Consolidated Balance Sheets as of December 31, 2021. 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 part of acquisition accounting, the MTS acquisition resulted in the recognition of $741.1 of goodwill, $54.0 of indefinite-lived tradename intangible assets and $178.2 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 $122.9, $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 $47.0 of deferred tax liabilities associated with certain basis differences, the majority of which the Company recognized for tax purposes and paid in the fourth quarter of 2021 upon the sale of the Divested MTS business. 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 the MTS Sensors business, along with other intangible assets acquired that do not qualify for separate recognition. The Company does not expect any such recognized goodwill associated with the acquisition of the MTS Sensors business to be deductible for tax purposes. Since the current purchase price allocation is based on preliminary assessments made by management as of December 31, 2021, the acquisition accounting is subject to final adjustment and it is possible that the final assessment of values may differ from this preliminary assessment. The operating results for the MTS Sensors business have been included within continuing operations in the Consolidated Statements of Income since the acquisition date, while the operating results for the Divested MTS business have been classified and reported as discontinued operations as discussed further in Note 12 herein. Acquisition of Halo Technology Limited On December 1, 2021, the Company completed the acquisition of approximately 97% of the common stock of Halo Technology Limited (“Halo”) for a purchase price of approximately $694, net of cash acquired. The sellers retained a less than 3% noncontrolling interest in Halo, which includes redeemable features that are outside the control of the Company and therefore, has been classified as temporary equity on the Consolidated Balance Sheet as of December 31, 2021, as discussed in more detail in Notes 1 and 5 herein. The acquisition was funded with cash on hand. Halo, which is headquartered in the United States (California), is a leading provider of active and passive fiber optic interconnect components, with product offerings that are highly complementary to our existing high-speed and fiber optic interconnect solutions for the communications infrastructure markets. The Company has begun the process of analyzing the allocation of the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed, as part of acquisition accounting. As of December 31, 2021, the Halo acquisition resulted in the recognition of $528.3 of goodwill, $28.0 of indefinite-lived tradename intangible assets and $156.0 of definite-lived intangible assets. The definite-lived intangible assets are comprised of customer relationships, proprietary technology, and backlog of $31.0, $116.0 and $9.0, respectively, and are amortized based upon the underlying pattern of economic benefit with weighted average useful lives of 10 years, 15 years and one month, respectively. Other than these intangible assets, the remainder of the purchase price has been allocated to other identifiable assets acquired and liabilities and noncontrolling interests (including redeemable noncontrolling interests) assumed. As part of acquisition accounting, the excess purchase price over the fair value of the underlying assets acquired (net of liabilities and noncontrolling interests 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 Halo, along with other intangible assets acquired that do not qualify for separate recognition. The Company does not expect any such recognized goodwill associated with the Halo acquisition to be deductible for tax purposes. Since the current purchase price allocation is based on an initial preliminary assessment made by management as of December 31, 2021, the acquisition accounting for Halo is subject to final adjustment and it is possible that the final assessment of values may differ from our initial preliminary assessment. The operating results for Halo have been included within continuing operations in the Consolidated Statements of Income since the acquisition date. The acquisition of Halo, which is reported within our Interconnect Products and Assemblies segment, was not material to the Company’s financial results. 2020 Acquisitions During the year ended December 31, 2020, the Company completed two acquisitions for $50.4, net of cash acquired, both of which were included in the Interconnect Products and Assemblies segment. The Company completed the acquisition accounting, including the analyses of the fair value of the assets acquired and liabilities assumed, for both 2020 acquisitions, and the final assessments of values did 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. 2019 Acquisitions During the year ended December 31, 2019, the Company completed nine acquisitions for $937.4, net of cash acquired. All but one of the acquisitions were included in the Interconnect Products and Assemblies segment. The 2019 acquisitions resulted in the recognition, in 2019, of $784.6 of goodwill and $111.8 of definite-lived intangible assets, primarily related to customer relationships and proprietary technology, with the remainder of the purchase price being allocated to other identifiable assets acquired and liabilities and noncontrolling interests assumed. These definite-lived intangible assets are being amortized based upon the underlying pattern of economic benefit, with the vast majority having useful lives ranging from 5 to 10 years. The excess purchase price over the fair value of the underlying net assets acquired was allocated to goodwill, which primarily represents the value of the assembled workforce along with other intangible assets acquired that do not qualify for separate recognition. Approximately $455 of the goodwill recognized from acquisitions in 2019 will be deductible for tax purposes. The Company completed the acquisition accounting, including its analyses of the fair value of the assets acquired and liabilities assumed, for all 2019 acquisitions, and the final assessments of values did not differ materially from the preliminary assessments. The operating results of the 2019 acquisitions have been included in the 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, was not presented, since these acquisitions were not material, either individually or in the aggregate, to the Company’s financial results. In January 2019, the Company acquired SSI Controls Technologies (“SSI”), the sensor manufacturing division of SSI Technologies, Inc., for approximately $400, net of cash acquired, plus a performance-related contingent payment. SSI, which is headquartered in the United States (Wisconsin), is a leading designer and manufacturer of sensors and sensing solutions for the global automotive and industrial markets. The SSI acquisition was not material to the Company. The contingent consideration payment was based on certain 2019 revenue and profitability levels of SSI. The Company determined the fair value of this liability using Level 3 unobservable inputs, such as probability weighted payout projections, and is classified as Level 3 in the fair value hierarchy (Note 5). The calculation of the contingent consideration was finalized in the first quarter of 2020 as $75.0, based on actual financial data used for inputs, and was paid in the second quarter of 2020. Acquisition-related Expenses In 2021, the Company incurred $70.4 ($57.3 after-tax) of acquisition-related expenses, comprised primarily of transaction, severance, restructuring and certain non-cash purchase accounting costs related to the MTS acquisition in the second quarter of 2021, along with external transaction costs and certain non-cash purchase accounting costs related to the Halo acquisition in the fourth quarter of 2021. In 2020, the Company incurred approximately $11.5 ($10.7 after-tax) of acquisition-related expenses, comprised primarily of external transaction costs related to acquisitions that were announced or closed. In 2019, the Company incurred approximately $25.4 ($21.0 after-tax) of acquisition-related expenses, comprised primarily of the amortization of $15.7 related to the value associated with acquired backlog (of which $12.5 related to the acquisition of SSI), with the remainder representing external transaction costs. Such acquisition-related expenses are separately presented in the accompanying Consolidated Statements of Income.
