Orders of $10.7 billion, resulting in a book-to-bill of 1.23:1
GAAP Diluted EPS of $1.37, up 59% compared to prior year
Adjusted Diluted EPS of $1.35, up 67% compared to prior year
GAAP and Adjusted Operating Margin of 29.5% and 29.8%, respectively

Amphenol Corporation (NYSE:APH) today reported record second quarter 2026 results.

"We are pleased to have closed the second quarter of 2026 with record sales and Adjusted Diluted EPS, both exceeding the high end of our guidance," said Amphenol Chairman and Chief Executive Officer, R. Adam Norwitt. "Sales increased from prior year by 55%, driven by strong organic growth in most of our end markets, including exceptional organic growth in the IT datacom market, as well as contributions from the Company’s acquisition program. We also booked record orders in the quarter, resulting in a book-to-bill of 1.23:1. The Company realized strong profitability during the quarter with Adjusted Operating Margin reaching 29.8%, inclusive of $80 million in net tariff recoveries. 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 1.5 million shares of its common stock for $208 million and paid dividends of $307 million, resulting in total capital returned to shareholders of $515 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, Amphenol acquired two companies during the second quarter, El.Com and Wilder Technologies. Based in Leno, Italy and with annual sales of approximately $150 million, El.Com is a leading manufacturer of complex interconnect solutions and high-voltage cable assemblies serving the industrial, defense and commercial aerospace markets. Based in Vancouver, Washington and with annual sales of approximately $15 million, Wilder Technologies is a key supplier to the Company of high-performance test and measurement solutions for high-speed digital, RF and signal integrity applications to the IT datacom market. El.Com is included in the Interconnect and Sensor Systems segment and Wilder Technologies is included in the Communications Solutions segment. In addition, given the better than expected performance of CommScope, Amphenol now expects this acquisition to generate full-year sales of $4.6 billion and to be $0.30 accretive to the Company’s Adjusted Diluted EPS in 2026. This is above our prior expectations for sales and accretion of $4.1 billion and $0.15, respectively.

Third Quarter 2026 Outlook

Assuming the continuation of current market conditions as well as constant exchange rates, for the third quarter of 2026, Amphenol expects sales to be in the range of $9.3 billion to $9.4 billion, representing a 50% to 52% increase over the prior year quarter. Adjusted Diluted EPS is expected to be in the range of $1.40 to $1.42, representing a 51% to 53% increase from the third quarter of 2025. This guidance does not include any additional tariff recoveries.

Mr. Norwitt continued, "I am very pleased with the Company’s outstanding second quarter 2026 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 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."

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 book to bill, Constant Currency Net Sales Growth, Organic Net Sales Growth, Adjusted Operating Income, Adjusted Operating Margin, Adjusted Net Income attributable to Amphenol Corporation, Adjusted Effective Tax Rate, Adjusted Diluted EPS 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. The Company’s book-to-bill is the ratio of orders received to net sales during the period. Constant Currency Net Sales Growth excludes the impact of foreign currency exchange rate changes. Organic Net Sales Growth excludes the impact of foreign currency exchange rate changes 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 in the presentation of these non-GAAP financial measures in any period may consist of, without limitation, acquisition-related expenses, refinancing-related costs, the excess tax benefits related to stock-based compensation and certain other discrete tax items including, but not limited to, (i) the impact of tax audits relating to prior periods and (ii) significant changes in tax law. Free Cash Flow is defined as Net Cash Provided by Operating Activities less capital expenditures net of proceeds from disposals. 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.

difficulties and unanticipated expenses in connection with purchasing and integrating newly acquired businesses, including the potential for the impairment of goodwill and other intangible assets; events beyond the Company’s control that could lead to an inability to meet its financial and other covenants and requirements, which could result in a default under the Company’s credit agreements or any of our various senior notes; risks associated with increased debt and interest expense as a result of the CommScope acquisition; risks associated with the Company’s inability to access the global capital markets on favorable terms, including as a result of significant deterioration of general economic or capital market conditions, or as a result of a downgrade in the Company’s credit rating; changes in interest rates; government contracting risks that the Company may be subject to, including laws and regulations governing reporting obligations, performance of government contracts and related risks associated with conducting business with the U.S. and other foreign governments or their suppliers (both directly and indirectly); governmental export and import controls as well as sanctions and trade embargoes that certain of our products may be subject to, including export licensing, customs regulations, economic sanctions and other laws;

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. Constant Currency Net Sales Growth excludes the impact of foreign currency exchange rate changes. Organic Net Sales Growth excludes the impact of foreign currency exchange rate changes 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 in the presentation of these non-GAAP financial measures in any period may consist of, without limitation, acquisition-related expenses, refinancing-related costs, the excess tax benefits related to stock-based compensation and certain other discrete tax items including, but not limited to, (i) the impact of tax audits relating to prior periods and (ii) significant changes in tax law. Free Cash Flow is defined as Net Cash Provided by Operating Activities less capital expenditures net of proceeds from disposals. 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:

(1) 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.

(i) While the terms "operating margin" and "effective tax rate" are not considered U.S. GAAP financial measures, for purposes of this table, we derive the reported (GAAP) measures based on GAAP results, which serve as the basis for the reconciliation to their comparable non-GAAP financial measures.

(ii) Amortization of acquisition-related inventory step-up costs is reported within Cost of sales in the Condensed Consolidated Statements of Income.

(iii) For the three and six months ended June 30, 2026, the Company recorded income tax related accruals of $39.0 million and $329.0 million, respectively. The amounts recorded during the three months ended June 30, 2026 primarily relate to reserves for potential settlement of various foreign tax matters. The amounts recorded during the six months ended June 30, 2026 also included $130.0 million primarily resulting from unfavorable determinations received from relevant tax authorities in China regarding certain of the Company’s prior period tax positions. In addition, the developments of the China tax matter also resulted in the Company reassessing certain tax rate assumptions applied to prior years’ results not subject to the China tax inquiries. This reassessment resulted in the Company recording $160.0 million of additional tax obligations in the six months ended June 30, 2026. As a result of this matter, as well as a continued shift in income to higher-tax jurisdictions, the Company increased its Adjusted Effective Tax Rate to 27.0%.

(iv) GAAP and Adjusted Operating Income for both the three and six months ended June 30, 2026 included an $80.0 million, or $0.04 per share, net benefit related to the recovery of IEEPA tariffs.

(v) 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.

(vi) 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, the excess tax benefits related to stock-based compensation, and certain other discrete tax items including, but not limited to, (i) the impact of tax audits relating to prior periods and (ii) 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 reasonable 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, 2026.
