Amphenol Corporation (NYSE: APH) today reported second quarter 2021 results.

“We are pleased to have closed the second quarter with sales and Adjusted Diluted EPS exceeding the high end of our guidance,” said Amphenol President and Chief Executive Officer, R. Adam Norwitt. “Sales increased by a strong 34% in the quarter, with growth driven in particular by the automotive, industrial, military and broadband markets as well as contributions from the Company’s acquisition program.”

“During the second quarter, Amphenol continued to deploy its financial strength in a variety of ways to increase shareholder value. To that end, the Company purchased 2.5 million shares of its common stock for $167 million. The Company also paid dividends of $87 million, resulting in total capital returned to shareholders during the second quarter of $254 million.”

“We remain focused on expanding our growth opportunities through a deep commitment to developing enabling technologies for customers across our served markets, an ongoing strategy of market and geographic diversification and an active and successful acquisition program. To that end, we are excited to have closed on the acquisition of Unlimited Services of Wisconsin, Inc. at the end of April. Based in Oconto, Wisconsin and with annual sales of approximately $50 million, Unlimited Services is a manufacturer of cable assemblies for industrial applications with a particular focus on heavy vehicles. The acquisition further strengthens our capabilities and enhances our product offerings in the industrial market, while adding a talented management team to the Amphenol family.”

Third Quarter 2021 Outlook

Given the current dynamic market environment and assuming no new material disruptions from the COVID-19 pandemic as well as constant exchange rates, for the third quarter 2021, Amphenol expects sales from continuing operations to be in the range of $2.640 billion to $2.700 billion, representing 14% to 16% growth over the third quarter of 2020, and Adjusted Diluted EPS² from continuing operations in the range of $0.60 to $0.62, representing 9% to 13% growth over the third quarter of 2020.

“Despite the ongoing challenges and uncertainties that continue to arise from the COVID-19 pandemic, we are encouraged by the platform of strength that has been created by the Company’s performance,” Mr. Norwitt continued. “The revolution in electronics is accelerating, thereby creating exciting and dynamic long-term growth opportunities for Amphenol across each of our diversified end markets. We believe these opportunities will enable a further, long-term increase in the demand for our ever expanding range of high-technology interconnect, sensor and antenna products. Our ongoing drive to leverage our competitive advantages and create sustained financial strength, as well as our initiatives to expand our product offerings, both organically and through our acquisition program, have created an excellent base for the Company’s future performance. I am confident in the ability of our outstanding entrepreneurial management team 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. Most importantly, I remain truly grateful to our team for their extraordinary efforts to protect the safety and health of our employees around the world throughout the ongoing pandemic, all while continuing to strongly support our customers and drive outstanding operating performance.”

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”). This press release also contains certain non-GAAP financial measures, including Adjusted Operating Income, Adjusted Operating Margin, Adjusted Net Income from continuing operations attributable to Amphenol Corporation, Adjusted Effective Tax Rate, Adjusted Diluted EPS from continuing operations, Organic 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, in addition to the reasons noted later within this press release. Non-GAAP financial measures related to operating income, operating margin, net income from continuing operations attributable to Amphenol Corporation, effective tax rate and diluted EPS from continuing operations 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. All non-GAAP financial measures and their most directly comparable U.S. GAAP financial measures presented within this press release are on a continuing operations basis only and exclude any results associated with discontinued operations. 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 should not be considered in isolation, 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.

This press release may include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which relate to future events and are subject to risks and uncertainties. All statements that address events or developments that we expect or believe may or will occur in the future are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. The forward-looking statements, which address the Company’s expected business and financial performance and financial condition as well as expectations regarding the anticipated timing and estimated expenses associated with the closing of certain acquisitions and divestitures, among other matters, may contain words and terms such as: “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “guidance,” “intend,” “look ahead,” “may,” “ongoing,” “optimistic,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will” or “would” and other words and terms of similar meaning. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about expected earnings, revenues, growth, liquidity or other financial matters, together with any forward-looking statements related in any way to the COVID-19 pandemic, including its future impact on the Company. Although the Company believes the expectations reflected in all forward-looking statements, including those regarding third quarter 2021 sales and Adjusted Diluted EPS from continuing operations, among other matters, are based upon reasonable assumptions, the expectations may not be attained or there may be material deviation. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made.

There are risks and uncertainties that could cause actual results to differ materially from these forward-looking statements, which include, but are not limited to, the following: future risks and existing uncertainties associated with adverse public health developments, including epidemics and pandemics such as the COVID-19 pandemic, which continues to disrupt our operations including, depending on the specific location, government regulations that limit our ability to operate certain of our facilities at full capacity or at all and to adjust certain costs, travel restrictions, “work-from-home” orders, supplier constraints, supply-chain interruptions, logistics challenges and limitations, and reduced demand from certain customers; uncertainties associated with a protracted economic slowdown that could negatively affect the financial condition of our customers; uncertainties and volatility in the global capital markets; political, economic, military and other risks in countries outside the United States; the impact of general economic conditions, geopolitical conditions and U.S. trade policies, legislation, trade disputes, treaties and tariffs, including those affecting China, on the Company’s business operations; risks associated with the improper conduct by any of our employees, customers, suppliers, distributors or any other business partners which could impair our business reputation and financial results and could result in our non-compliance with anti-corruption laws and regulations of the U.S. government and various foreign jurisdictions; changes in exchange rates of the various currencies in which the Company conducts business; the Company’s ability to obtain a consistent supply of materials, at stable pricing levels; the Company’s dependence on sales to the communications industry, which markets are dominated by large manufacturers and operators who regularly exert significant pressure on suppliers, including the Company; changes in defense expenditures in the military market, including the impact of reductions or changes in the defense budgets of U.S. and foreign governments; the Company’s ability to compete successfully on the basis of technology innovation, product quality and performance, price, customer service and delivery time; the Company’s ability to continue to conceive, design, manufacture and market new products and ability to rely upon continuing market acceptance of its existing and future product lines; 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 covenants, which could result in a default under the Company’s revolving credit facility; the Company’s ability to access the 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 performance of U.S. government contracts and related risks associated with conducting business with the U.S. government or its suppliers (both directly and indirectly); governmental export and import controls that certain of our products may be subject to, including export licensing, customs regulations, economic sanctions or other laws; cybersecurity threats, malware, phishing, ransomware or other increasingly sophisticated attacks, that could impair our information technology systems and could disrupt business operations, result in a loss of or inability to access confidential information and critical business, financial or other data, and/or cause the release of highly sensitive confidential information and adversely impact our reputation and operating results and potentially lead to litigation and/or governmental investigations; changes in fiscal and tax policies, audits and examinations by taxing authorities, laws, regulations and guidance in the United States and foreign jurisdictions; any difficulties in protecting the Company’s intellectual property rights; and litigation, customer claims, product recalls, governmental investigations, criminal liability or environmental matters including changes to laws and regulations to which the Company may be subject. In addition, the extent to which the COVID-19 pandemic will continue to impact our business and financial results going forward will be dependent on future developments such as the length and severity of the crisis, any potential resurgence of the crisis including from the recent, more transmissible Delta variant strain, future government regulations and actions in response to the crisis, the timing, availability, effectiveness and adoption rates of vaccines, and the overall impact of the COVID-19 pandemic on the global economy and capital markets, among many other factors, all of which remain highly uncertain and unpredictable.

A further description of these uncertainties and other risks can be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, Quarterly Reports on Form 10-Q and the Company’s other reports filed with the Securities and Exchange Commission. These or other uncertainties may cause the Company’s actual future results to be materially different from those expressed in any forward-looking statements. The Company undertakes no obligation to update or revise any forward-looking statements except as required by law.
