Acquired Narda-MITEQ in May

Wallingford, Connecticut, July 23, 2025. Amphenol Corporation (NYSE: APH) today reported record second quarter 2025 results.

“We are pleased to have closed the second quarter of 2025 with record sales and Adjusted Diluted EPS, both significantly exceeding the high end of our guidance,” said Amphenol President and Chief Executive Officer, R. Adam Norwitt. “Sales increased from prior year by 57%, driven by strong organic growth in all of our end markets including exceptional organic growth in the IT datacom market as well as contributions from the Company’s acquisition program. In the second quarter, we once again realized excellent profitability with Adjusted Operating Margin reaching a record 25.6%. We are extremely proud of the Company’s outstanding performance.”

The Company continues to deploy its financial strength in a variety of ways to increase shareholder value. During the second quarter, the Company purchased 2.0 million shares of its common stock for $160 million and paid dividends of $200 million, resulting in total capital returned to shareholders of approximately $360 million.

Amphenol remains focused on expanding its growth opportunities through a deep commitment to developing enabling technologies for customers across our served end markets, an ongoing strategy of market and geographic diversification as well as an active and successful acquisition program. To that end, we are excited to have closed on Narda-MITEQ (“Narda”) in May 2025. Based in Hauppauge, New York, with annual sales of approximately $120 million, Narda designs and manufactures active RF interconnect components that complement our product offering primarily serving the defense market. The Narda business is included in the Harsh Environment Solutions Segment.

Third Quarter 2025 Outlook

Assuming the continuation of current market conditions as well as constant exchange rates, for the third quarter of 2025, Amphenol expects sales to be in the range of $5.4 billion to $5.5 billion, representing a 34% to 36% increase over the prior year quarter. Adjusted Diluted EPS is expected to be in the range of $0.77 to $0.79, representing a 54% to 58% increase from the third quarter of 2024.

Mr. Norwitt continued, “I am very pleased with the Company’s outstanding second quarter 2025 results. The revolution in electronics continues to accelerate, with new innovations creating exciting growth opportunities for Amphenol across each of our diversified end markets. In turn, we have expanded our range of high-technology interconnect products, both through our organic innovation efforts as well as through our successful acquisition program. This expanded technology position coupled with our unique entrepreneurial culture has strengthened our competitive advantage. Our ongoing drive to leverage that competitive advantage and thereby create sustained financial strength has established an excellent base for the Company’s future performance. I am confident in the ability of our outstanding and expanding entrepreneurial management team to continue to dynamically adjust to changing market conditions, to capitalize on the wide array of growth opportunities that arise in all market cycles and to continue to generate sustainable long-term value for our shareholders and other stakeholders.”

Non-GAAP Financial Measures

The financial statements included within this press release are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP” or “U.S. GAAP”). This press release also contains certain non-GAAP financial measures, including Adjusted Operating Income, Adjusted Operating Margin, Adjusted Net Income attributable to Amphenol Corporation, Adjusted Effective Tax Rate, Adjusted Diluted EPS, Organic Net Sales Growth, and Free Cash Flow (collectively, “non-GAAP financial measures”), which are intended to supplement the reported GAAP results. Management utilizes these non-GAAP financial measures 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 such non-GAAP financial measures may be helpful to investors in assessing the Company’s overall financial performance, trends and period-over-period comparative results. Non-GAAP financial measures related to operating income, operating margin, net income attributable to Amphenol Corporation, effective tax rate and diluted EPS 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 these 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 related to foreign currency exchange and acquisitions. Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures are included at the end of this press release. However, such non-GAAP financial measures are included for supplemental purposes only and should not be considered in isolation or 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 are defined within the “Supplemental Financial Information” table at the end of this press release and should be read in conjunction with the Company’s financial statements presented in accordance with U.S. GAAP.

SUPPLEMENTAL FINANCIAL INFORMATION

RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES

(Unaudited)

(dollars in millions, except per share data)

Management utilizes the 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 such non-GAAP financial measures may be helpful to investors in assessing the Company’s overall financial performance, trends and period-over-period comparative results. Non-GAAP financial measures related to net sales exclude the impact of foreign currency exchange rates and acquisitions. Non-GAAP financial measures related to operating income, operating margin, net income attributable to Amphenol Corporation, effective tax rate and diluted EPS exclude income and expenses that are not directly related to the Company’s operating performance during the periods presented. Items excluded from such non-GAAP financial measures in any period may consist of, without limitation, acquisition-related expenses, refinancing-related costs, gains associated with bargain purchase acquisitions, 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. The following non-GAAP financial information is included for supplemental purposes only and should not be considered in isolation or 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. Such non-GAAP financial measures should be read in conjunction with the Company’s financial statements presented in accordance with U.S. GAAP.

The following are reconciliations of non-GAAP financial measures to the most directly comparable U.S. GAAP financial measures for the periods presented:

Percentages in this table were calculated using actual, unrounded results; therefore, the sum of the components may not add due to rounding.

(2)

Net sales growth in U.S. dollars is calculated based on Net sales as reported in the Condensed Consolidated Statements of Income. 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.

(3)

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 respective period(s) in the prior year. Such amount is calculated by subtracting net sales for the current reporting period(s) translated at average foreign currency exchange rates for the respective prior year period(s) from net sales for the current reporting period(s), taken as a percentage of the respective prior year period(s) net sales.

(4)

Acquisition impact, a non-GAAP measure, represents the percentage impact on net sales resulting from acquisitions 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. Acquisition impact is calculated as a percentage of the respective prior year period(s) net sales.

(5)

The following are definitions of certain non-GAAP financial measures presented in the table(s) above, which may be referred to within this press release. For purposes of this press release, the terms “constant currencies” and “organically” have the same meaning as the following non-GAAP financial measures, respectively:

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.

Organic Net Sales Growth is defined as the period-over-period percentage change in net sales growth resulting from operating volume, pricing changes and sales mix and excludes (i) the foreign currency translation impact, which is outside the control of the Company, and (ii) the acquisition impact, both as described above and which 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.

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.

(iv)	The following are definitions of non-GAAP financial measures presented in the tables above, which may be referred to within this press release:

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).

Adjusted Net Income attributable to Amphenol Corporation is defined as Net income attributable to Amphenol Corporation (as reported in the Condensed Consolidated 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 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 before income taxes (as reported in the Condensed Consolidated Statements of Income), each 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 defined as diluted earnings per share (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 attributable to Amphenol Corporation, as defined above, divided by the weighted average outstanding diluted shares (as reported in the Condensed Consolidated Statements of Income).

Free Cash Flow is defined as (i) Net cash provided by operating activities (“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 stockholders through either stock repurchases or dividends.

RECONCILIATIONS OF GAAP TO NON-GAAP FINANCIAL MEASURES - GUIDANCE

(Unaudited)

(dollars in millions, except per share data)

Management utilizes the non-GAAP financial measures defined earlier 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 such non-GAAP financial measures may be helpful to investors in assessing the Company’s overall financial performance, trends and period-over-period comparative results. Adjusted Diluted EPS, a non-GAAP financial measure, excludes income and expenses that are not directly related to the Company’s operating performance during the periods presented. Items excluded from such non-GAAP financial measures in any period may consist of, without limitation, acquisition-related expenses, refinancing-related costs, gains associated with bargain purchase acquisitions, 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. Adjusted Diluted EPS is 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. Such non-GAAP financial measures should be read in conjunction with the Company’s financial statements presented in accordance with U.S. GAAP.

The Company excludes the above items in its guidance for the upcoming quarter only to the extent that the Company reasonably expects to record such items in the forward-looking period presented and such amounts are estimable. As the Company has not yet identified any such items for the forward-looking period presented, there are currently no reconciling items for the three months ended September 30, 2025.
