2025 Acquisitions

During the first nine months of 2025, the Company completed four acquisitions (collectively, the “2025 Acquisitions”), including the acquisition of the Andrew Business from CommScope, for approximately $2,772.2, net of cash acquired. The Andrew Business has been included in the Communications Solutions segment, two acquisitions have been included in the Harsh Environment Solutions segment, and one acquisition has been included in the Interconnect and Sensor Systems segment. The 2025 Acquisitions were each funded using cash on hand, proceeds from the October Senior Notes, 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 the assets acquired and liabilities assumed for each of the 2025 Acquisitions. Since the current purchase price allocations for such acquisitions are based on preliminary assessments made by management as of September 30, 2025, 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 2025 Acquisitions were 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 allocations related to these acquisitions, have not been presented, since the 2025 Acquisitions were not material, either individually or in the aggregate, to the Company’s financial results.

Acquisition of Andrew Business from CommScope

On January 31, 2025, pursuant to a purchase agreement with CommScope, dated July 18, 2024, the Company completed the acquisition of the Andrew Business from CommScope for an aggregate purchase price of approximately $2,022.7, net of cash acquired and subject to customary post-closing adjustments. The Andrew Business provides communications network solutions, with advanced technologies in the area of base station antennas and related interconnect solutions, as well as distributed antenna systems. The Andrew Business’s wide range of products add advanced antenna and associated interconnect products, technologies and capabilities, which management believes are highly complementary to Amphenol’s existing product portfolio for next-generation wireless networks. The Andrew Business has been included in the Communications Solutions segment.

As of September 30, 2025, the acquisition of the Andrew Business resulted in the recognition of $875.0 of goodwill and $800.0 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 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 12 to 15 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 net 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 $813.0 of the goodwill recognized from the Andrew Business will be deductible for tax purposes.

During the nine months ended September 30, 2025, the Company incurred $133.8 ($106.3 after-tax) of acquisition-related expenses, comprised primarily of (i) the non-cash amortization related to the value associated with acquired backlog resulting from the Andrew Business acquisition and external transaction costs related to acquisitions (such acquisition-related expenses aggregating $56.0 are presented separately in the Condensed Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $77.8 associated with the Andrew Business acquisition (such costs are recorded in Cost of sales in the Condensed Consolidated Statements of Income).

2024 Acquisitions

During the year ended December 31, 2024, the Company completed two acquisitions (collectively, the “2024 Acquisitions”), including the acquisition of 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.

As of September 30, 2025, the 2024 Acquisitions resulted in the recognition of $1,198.2 of goodwill and $576.0 of definite-lived intangible assets, comprised of customer relationships and acquired backlog, with the remainder of the purchase price being allocated to other identifiable assets acquired and liabilities 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 having useful lives ranging from 8 to 15 years and the acquired backlog having a useful life of approximately 0.4 years. 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 $61.2 of the goodwill recognized from the 2024 Acquisitions will be deductible for tax purposes.

The Company completed the acquisition accounting, including the analyses of fair value of assets acquired and liabilities assumed, for the acquisition of CIT, and the final assessment of values did not differ materially from the previous preliminary assessment. The Company is in the process of analyzing and completing the allocation of the fair value of assets acquired and liabilities assumed for the other 2024 Acquisition. Since the current purchase price allocation for such other acquisition is based on a preliminary assessment made by management as of September 30, 2025, the acquisition accounting is subject to final adjustments, and it is possible that the final assessment of values may differ from the Company’s preliminary assessment. The operating results of the 2024 Acquisitions were 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 allocations related to these acquisitions, were not presented, since the 2024 Acquisitions were not material, either individually or in the aggregate, to the Company’s financial results.

During the three and nine months ended September 30, 2024, the Company incurred $63.6 ($49.8 after-tax) and $133.6 ($109.7 after-tax), respectively, of acquisition-related expenses, comprised primarily of (i) the amortization of the value associated with the acquired backlog resulting from the CIT acquisition and external transaction costs associated with acquisitions (such acquisition-related expenses aggregating $45.4 and $115.4, respectively, which are presented separately in the Condensed Consolidated Statements of Income) and (ii) the amortization of acquisition-related

inventory step-up costs in the third quarter of 2024 of $18.2 associated with the CIT acquisition (such costs are recorded in Cost of sales in the Condensed Consolidated Statements of Income).

Purchase Agreement to Acquire CommScope’s Connectivity and Cable Solutions Business

On August 4, 2025, the Company entered into a Purchase Agreement with CommScope to acquire its CCS Business, for an aggregate purchase price of approximately $10,500 in cash, subject to customary post-closing adjustments. Subject to the receipt of certain regulatory approvals and satisfaction of other customary closing conditions, the acquisition is expected to close by the end of the first quarter of 2026. The Company expects to finance this acquisition through a combination of cash on hand and debt. In connection with its entry into the Purchase Agreement, the Company obtained a commitment from JPMorgan Chase Bank, N.A., BNP Paribas, BNP Paribas Securities Corp. and Mizuho Bank, Ltd. for a $10,500 senior unsecured bridge facility, subject to customary conditions. A portion ($4,000) of such financing was replaced by the Delayed Draw Term Loans, as discussed in Note 4 herein, and the remaining $6,500 is expected to be replaced by the issuance of new senior unsecured notes prior to the closing of the acquisition. The CCS Business would expand the Company’s interconnect product capabilities in the IT datacom, communications networks and industrial markets, particularly adding complementary fiber optic interconnect capabilities. If, and when, the acquisition is consummated, the Company expects to report the CCS Business within its Communications Solutions segment.

Purchase Agreement to Acquire Trexon

On August 18, 2025, the Company announced that it had entered into a definitive agreement to acquire Trexon, for an aggregate purchase price of approximately $1,000 in cash, subject to customary post-closing adjustments. Subject to the receipt of certain regulatory approvals and satisfaction of other customary closing conditions, the acquisition is expected to close by the end of the fourth quarter of 2025. The Company expects to finance this acquisition with cash on hand. Trexon would expand the Company’s high-reliability interconnect and cable assembly capabilities, primarily for the defense market. If, and when, the acquisition is consummated, the Company expects to report Trexon within its Harsh Environment Solutions segment.
