Amphenol Corporation (NYSE: APH) today reported fourth quarter and full year 2022 results.

“We are pleased to have closed 2022 with fourth quarter sales and Adjusted Diluted EPS both exceeding the high end of our guidance,” said Amphenol President and Chief Executive Officer, R. Adam Norwitt. “Sales increased from prior year by 7%, supported by robust growth in our broadband communications, commercial air, automotive and military markets and moderate growth in our industrial market, as well as contributions from the Company’s acquisition program, which were partially offset by the impact of the strengthening U.S. dollar. For the full year, sales increased 16% compared to 2021, driven by strong growth across virtually all of our end markets, along with contributions from the Company’s acquisition program, which were partially offset by the impact of the strengthening U.S. dollar. Despite facing inflationary and supply chain challenges throughout the year, we again realized strong profitability in 2022, with Adjusted Diluted EPS growing an impressive 21%. We are very proud of the Company’s outstanding performance in this dynamic year.”

“During the fourth quarter and throughout 2022, Amphenol continued to deploy its financial strength in a variety of ways to increase shareholder value. During the fourth quarter, the Company purchased 2.3 million shares of its common stock for $170 million and paid dividends of $119 million, resulting in total capital returned to shareholders in 2022 of more than $1.2 billion.”

“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. In addition to our previously announced 2022 acquisitions, we are excited to have closed on the acquisition of Control Measure Regulation Group (CMR) in January 2023. Based in France and with manufacturing locations in Tunisia, China and India, CMR manufactures cable assemblies and complex interconnect assemblies for the industrial market, particularly for heavy vehicle engine applications, and has annual sales of approximately $75 million. This acquisition further expands our offering of high-technology, value-added interconnect products in the diversified industrial market, while adding another talented management team to the Amphenol family.”

“We are also excited to announce that at the end of December 2022, we signed an agreement to acquire the North American cable and global base station antenna businesses of RFS. Based in Meriden, Connecticut, RFS designs and manufactures radio frequency and hybrid power and fiber optic cable for North American customers, as well as base station antennas for global customers in the mobile networks markets. We anticipate that the acquired businesses will generate full year 2023 sales of approximately $100 million and we expect to close the transaction by the end of the second quarter of 2023, subject to satisfying certain standard closing conditions.”

First Quarter 2023 Outlook

The current economic environment remains uncertain. In addition, as we discussed last quarter, we have seen some continued moderation in demand in the communications-related markets. Assuming market conditions do not meaningfully worsen as well as constant exchange rates, for the first quarter of 2023, Amphenol expects sales to be in the range of $2.840 billion to $2.900 billion. This represents a 2% to 4% decline over the first quarter of 2022 and includes a two percentage point negative currency impact. Adjusted Diluted EPS is expected to be in the range of $0.65 to $0.67, representing a 3% decline to flat over the first quarter of 2022.

“Despite the ongoing challenges and uncertainties around the world, we are very pleased with the Company’s strong fourth quarter and full year 2022 results,” Mr. Norwitt continued. “The revolution in electronics continues to accelerate, creating exciting and dynamic long-term growth opportunities for Amphenol across each of our diversified end markets. 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 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. Most importantly, I remain truly grateful to our team for their extraordinary efforts in navigating the myriad of challenges around the world 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” or “U.S. 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 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 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 are included for supplemental purposes only and 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.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about expected earnings, revenues, growth, liquidity, effective tax rate, interest rates or other matters. Although the Company believes the expectations reflected in all forward-looking statements, including those we may make regarding first quarter 2023 sales and Adjusted Diluted EPS, among other matters, are based upon reasonable assumptions, the expectations may not be attained or there may be material deviation. Readers and investors 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: political, economic, military and other risks related to operating in countries outside the United States, as well as changes in general economic conditions, geopolitical conditions, U.S. trade policies (including but not limited to sanctions) and other factors beyond the Company’s control; uncertainties associated with an economic slowdown or recession in any of the Company’s end markets that could negatively affect the financial condition of our customers and could result in reduced demand; future risks and existing uncertainties associated with adverse public health developments, including epidemics and pandemics, such as the COVID-19 pandemic, which have disrupted and may continue to disrupt our operations including government regulations that inhibit our ability to operate certain of our facilities in the ordinary course, travel restrictions, supplier constraints, supply chain interruptions, logistics challenges and limitations, labor disruptions and reduced demand from certain customers; risks associated with our inability to obtain certain raw materials and components, in light of supply chain and logistical challenges that caused and continue to cause supply chain constraints and commodity price increases on certain raw materials and components used by the Company; cybersecurity threats and techniques used to disrupt operations and gain unauthorized access to our information technology systems, including, but not limited to, malware, phishing, credential harvesting, ransomware and other increasingly sophisticated attacks, that continue to expand and evolve globally, which could, among other things, impair our information technology systems and disrupt business operations, result in reputational damage, loss of our intellectual property, the 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 potentially lead to litigation and/or governmental investigations and fines, among other risks; negative impacts caused by extreme weather conditions and natural catastrophic events, including those caused or intensified by climate change and global warming; 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 risks associated with the Company’s dependence on attracting, recruiting, hiring and retaining skilled employees, including as part of our various management teams; risks associated with the increasing scrutiny and expectations regarding environmental, social and corporate governance matters that could result in additional costs or risks or otherwise adversely impact our business; risks and difficulties in trying to compete successfully on the basis of technology innovation, product quality and performance, price, customer service and delivery time; the Company’s dependence on end market dynamics to sell its products, particularly in the communications, automotive and military end markets, pricing pressures resulting from large customers that regularly exert pressure on their suppliers, including the Company, and changes in defense expenditures of the U.S. and non-U.S. governments, which are subject to political and budgetary fluctuations and constraints, all of which could adversely affect our operating results; 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 revolving credit facility, unsecured term loan credit facility or any of our various senior notes; 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; 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 enforcing and protecting the Company’s intellectual property rights; litigation, customer claims, voluntary or forced product recalls, governmental investigations, criminal liability or environmental matters including changes to laws and regulations to which the Company may be subject; and incremental costs, risks and regulations associated with efforts to combat the negative effects of climate change. In addition, the extent to which the COVID-19 pandemic will continue to impact our business, operations, financial condition, liquidity and results of operations in the future remains 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, 2021, Quarterly Reports on Form 10-Q and the Company’s other reports filed with the Securities and Exchange Commission. These or other uncertainties not identified in these documents (that we either currently do not expect to have an adverse effect on our business or that we are unable to predict or identify at this time) 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.
