Acquisitions	Note 11—Acquisitions 2024 Acquisitions During the year ended December 31, 2024, the Company completed two acquisitions (the “2024 Acquisitions”), including the acquisition of Carlisle Interconnect Technologies (“CIT”), for approximately $2,156.4, net of cash acquired. Both acquisitions have been included in the Harsh Environment Solutions segment. The 2024 Acquisitions were each funded using cash on hand, proceeds from the April Senior Notes or borrowings under the U.S. Commercial Paper Program, or a combination thereof. The Company is in the process of analyzing and completing the allocation of the fair value of assets acquired and liabilities assumed for the 2024 Acquisitions. Since the current purchase price allocations for the 2024 Acquisitions are based on preliminary assessments made by management as of December 31, 2024, the acquisition accounting is subject to final adjustments, and it is possible that the final assessments of values may differ from the Company’s preliminary assessments. The operating results of the 2024 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 allocations related to these acquisitions, have not been presented, since the 2024 Acquisitions are not material, either individually or in the aggregate, to the Company’s financial results. Acquisition of Carlisle Interconnect Technologies (“CIT”) On May 21, 2024, pursuant to a definitive stock purchase agreement by and between the Company and Carlisle Companies Incorporated dated January 30, 2024, the Company completed the acquisition of CIT for approximately $1,995.3, net of cash acquired and subject to customary post-closing adjustments. The Company funded the CIT acquisition through a combination of net proceeds from the April Senior Notes, as discussed in Note 4 herein, together with borrowings under the U.S. Commercial Paper Program and cash on hand. CIT, headquartered in St. Augustine, FL, is a leading global supplier of harsh environment interconnect solutions, primarily to the commercial aerospace, defense and industrial end markets. CIT’s wide range of products include wire and cable, cable assemblies, contacts, connectors and sensors, which management believes are highly complementary to Amphenol’s existing interconnect and sensor solutions. As of December 31, 2024, the CIT acquisition resulted in the recognition of $1,113.7 of goodwill and $543.0 of definite-lived intangible assets, with the remainder of the purchase price being allocated to other identifiable assets acquired and liabilities assumed. Of the acquired definite-lived intangible assets, approximately $488.0 and $55.0 were assigned to customer relationships and acquired backlog, respectively. The acquired customer relationships and acquired backlog have a weighted average useful life of approximately 15 years and 0.4 years, respectively. These definite-lived intangible assets are being amortized based upon the underlying pattern of economic benefit as reflected by the future net cash inflows. 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 the assembled workforce along with other intangible assets acquired that do not qualify for separate recognition. The Company expects that none of the goodwill recognized from the CIT acquisition will be deductible for tax purposes. 2023 Acquisitions During the year ended December 31, 2023, the Company completed 10 acquisitions (the “2023 Acquisitions”) for approximately $970.4, net of cash acquired. Five of the acquisitions were included in the Harsh Environment Solutions segment, three acquisitions were included in the Interconnect and Sensor Systems segment, and two acquisitions were included in the Communications Solutions segment. The 2023 Acquisitions were each funded using cash on hand or borrowings under our Commercial Paper Programs, or a combination thereof. One of the 2023 Acquisitions, which closed in the second quarter of 2023, represented a bargain purchase, where the estimated fair value of assets acquired, net of liabilities assumed, exceeded the purchase price. The Company recognized a non-cash gain of $5.4 on the bargain purchase acquisition during the year ended December 31, 2023, which was recorded separately in the Company’s Consolidated Statements of Income. As of December 31, 2024, the 2023 Acquisitions resulted in the recognition of $667.4 of goodwill and $153.2 of definite-lived intangible assets, comprised of customer relationships, proprietary technology and acquired backlog, 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 as reflected by the future net cash inflows, with the acquired customer relationships and proprietary technology having useful lives ranging from 6 to 12 years and the acquired backlog having a useful life of approximately 0.25 years. 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 the assembled workforce along with other intangible assets acquired that do not qualify for separate recognition. The Company expects that approximately $151 of the goodwill recognized from the 2023 Acquisitions will be deductible for tax purposes. In 2024, the Company completed the acquisition accounting, including the analyses of the fair value of assets acquired and liabilities assumed, for all of the 2023 Acquisitions, and each of the final assessments of values did not differ materially from their previous preliminary assessments. The operating results of the 2023 Acquisitions were 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 allocations related to these acquisitions, were not presented, since the 2023 Acquisitions were not material, either individually or in the aggregate, to the Company’s financial results. 2022 Acquisitions During the year ended December 31, 2022, the Company completed two acquisitions (the “2022 Acquisitions”) for approximately $288.2, net of cash acquired. The 2022 Acquisitions were funded through a combination of borrowings under the U.S. Commercial Paper Program and cash on hand. One acquisition was included in the Harsh Environment Solutions segment, while the other acquisition was included in the Interconnect and Sensor Systems segment. The Company completed the acquisition accounting, including the analyses of the fair value of assets acquired and liabilities assumed, associated with the 2022 Acquisitions, and each of the final assessments of values did not differ materially from their previous preliminary assessments. The operating results of the 2022 Acquisitions were 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 allocations related to these acquisitions, were not presented, since the 2022 Acquisitions were not material, either individually or in the aggregate, to the Company’s financial results. Acquisition-related Expenses In 2024, the Company incurred $145.6 ($119.3 after-tax) of acquisition-related expenses, comprised primarily of (i) external transaction costs associated with acquisitions and the amortization of $55.0 related to the value associated with acquired backlog resulting from the CIT acquisition (such acquisition-related expenses aggregating $127.4 are presented separately in the accompanying Consolidated Statements of Income) and (ii) the amortization of acquisition-related inventory step-up costs of $18.2 associated with the CIT acquisition (such costs are recorded in Cost of sales in the accompanying Consolidated Statements of Income). In 2023, the Company incurred $34.6 ($30.2 after-tax) of acquisition-related expenses, comprised primarily of external transaction costs associated with the 2023 Acquisitions, as well as the amortization of $12.4 related to the value associated with acquired backlog resulting from three of the 2023 Acquisitions. In 2022, the Company incurred $21.5 ($18.4 after-tax) of acquisition-related expenses, comprised primarily of the amortization of $12.0 related to the value associated with acquired backlog resulting from the 2022 Acquisitions, along with external transaction costs. Such acquisition-related expenses incurred in 2023 and 2022 were presented separately in the accompanying Consolidated Statements of Income.
