New in FY2020

The COVID-19 pandemic has caused widespread disruptions to our Company throughout most of 2020, particularly during the first half of the year.

New in FY2020

During the first quarter of 2020, these disruptions were primarily limited to our operations in China, which were closed for three weeks during January and February due to government mandates.

New in FY2020

As the virus spread to the rest of the world beginning in March and continuing throughout the remainder of 2020, most of our other operations outside of China were also impacted.

New in FY2020

As of December 31, 2020, we continue to experience some disruptions, and at a minimum, we expect those disruptions to continue through the first half of 2021 and they could, potentially, extend for the full year and beyond.

New in FY2020

These disruptions have included and may continue to include, depending on the specific location, government regulations that limit our ability to operate certain of our facilities at full capacity 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.

New in FY2020

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, future government regulations and actions in response to the crisis, the timing, availability and effectiveness of vaccines, some of which have recently been approved and distributed for use, 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.

New in FY2020

In addition, the COVID-19 pandemic could impact the health of our management team and other employees.

New in FY2020

It is impossible to predict the overall future impact of the COVID-19 pandemic on our business, financial condition, liquidity and financial results, and there can be no assurance that the COVID-19 pandemic will not have a material and adverse effect on our financial results in the future during any quarter or period in which we are affected.

New in FY2020

In addition, the COVID-19 pandemic increases the likelihood and potential severity of other risks (including some discussed separately within this Item 1A.

New in FY2020

_Risk Factors_), including but not limited to, the following:

New in FY2020

| | ● | A protracted economic slowdown could negatively affect the financial condition of our customers, which may result in an increase in bankruptcies or insolvencies, a delay in payments and decreased sales. |

New in FY2020

| | ● | A scarcity of resources or other hardships caused by the COVID-19 pandemic may result in increased nationalism, protectionism and political tensions which may cause governments and/or other entities to take actions that may have a significant negative impact on the ability of the Company, its suppliers and its customers to conduct business. |

New in FY2020

| --- | --- | --- |

New in FY2020

| | ● | We have transitioned a significant subset of our employee population to a remote work environment in an effort to mitigate the spread of COVID-19. This change may exacerbate certain risks to our business, including an increased demand for information technology resources, an increased risk of phishing and other cybersecurity attacks, and an increased risk of unauthorized dissemination of sensitive personal information or proprietary or confidential information. |

New in FY2020

| --- | --- | --- |

New in FY2020

| | ● | If the vaccines that have recently been approved and distributed for use prove ineffective, we could experience another disruption in the global capital markets, which could increase the cost of, and adversely impact access to, capital (including the commercial paper markets) and increase economic uncertainty. |

| | ● | If the financial performance of our businesses were to decline significantly as a result of the COVID-19 pandemic, we could incur a material non-cash charge to our income statement for the impairment of goodwill and other intangible assets. |

New in FY2020

For example, the COVID-19 pandemic initially disrupted the supply of raw materials, primarily in the first half of 2020; reoccurrences of such unforeseen events may result in the Company experiencing difficulties in obtaining a consistent supply of materials at stable pricing levels.

New in FY2020

Accordingly, such delays and associated risks could have an adverse effect on our business, results of operations and financial condition.

On December 9, 2020, the Company announced that we had entered into a definitive agreement to acquire MTS Systems Corporation (“MTS”) for $58.50 per share in cash, or approximately $1.7 billion, net of cash acquired and including the assumption of outstanding debt and liabilities.

New in FY2020

On January 19, 2021, the Company announced that we had entered into an agreement to sell the MTS Test & Simulation (“T&S”) business to Illinois Tool Works Inc. (“ITW”).

New in FY2020

The agreement to acquire MTS is expected to close by the middle of 2021, but is subject to certain regulatory approvals, approval from MTS’s shareholders and other customary closing conditions.

New in FY2020

The sale of the MTS T&S business to ITW is expected to close following the anticipated closing of our acquisition of MTS, but is also subject to certain regulatory approvals and other customary closing conditions.

New in FY2020

The acquisition of MTS and the sale of the MTS T&S business to ITW are subject to a number of risks that include, but are not limited to: (i) the risk that the proposed merger between Amphenol and MTS, and/or the proposed subsequent sale of the MTS T&S business to ITW, may not be completed in a timely manner or at all, (ii) unanticipated difficulties or expenditures relating to the proposed transactions, the response of business partners and competitors to the announcement of the proposed transactions, potential disruptions to current plans and operations and/or potential difficulties in employee retention as a result of the announcement and pendency of the proposed transactions and (iii) the failure of the transactions, if completed, to deliver the financial benefits to Amphenol currently anticipated by the Amphenol management team.

New in FY2020

On December 4, 2020, the ICE Benchmark Administration published a consultation on its intention to extend the publication of certain U.S. dollar LIBOR (“USD LIBOR”) rates until June 30, 2023.

Impact of Coronavirus (“COVID-19”) on our Operations, Financial Condition, Liquidity and Results of Operations

New in FY2020

The COVID-19 pandemic has caused widespread disruptions to our Company during 2020, particularly during the first half of the year.

New in FY2020

During the first quarter, these disruptions were primarily limited to our operations in China, which were closed for three weeks during January and February due to government mandates.

New in FY2020

As the virus spread to the rest of the world beginning in March and continuing throughout the remainder of 2020, most of our other operations outside of China were also impacted.

New in FY2020

As of December 31, 2020, we continue to experience some disruptions, and at a minimum, we expect those disruptions to continue through the first half of 2021 and they could, potentially, extend for the full year and beyond.

New in FY2020

These disruptions have included and may continue to include, depending on the specific location, government regulations that limit our ability to operate certain of our facilities at full capacity 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.

New in FY2020

During the fourth quarter of 2020 and into 2021, in several regions around the world, including the United States and Europe, there has been a resurgence in COVID-19 cases.

New in FY2020

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, future government regulations and actions in response to the crisis, the timing, availability and effectiveness of vaccines, some of which have recently been approved and distributed for use, 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.

New in FY2020

In addition, the COVID-19 pandemic could impact the health of our management team and other employees.

New in FY2020

The Company continues taking actions to mitigate, as best we can, the impact of the COVID-19 pandemic on the health and well-being of our employees, the communities in which we operate and our partners, as well as the impact on our operations and business as a whole.

New in FY2020

However, there can be no assurance that the COVID-19 pandemic will not have a material and adverse impact on our operations, financial condition, liquidity and results of operations.

New in FY2020

2020 Compared to 2019

New in FY2020

The increase in net sales in 2020 was driven by strong growth in several markets, which was partially offset by the sudden and severe slowdown in certain of our markets resulting from the global outbreak of the COVID-19 pandemic, which also caused production disruptions in many parts of the world during much of the first half of 2020.

New in FY2020

This sales growth was partially offset by declines in the commercial aerospace, mobile networks and automotive markets, all of which were negatively impacted by the COVID-19 pandemic.

New in FY2020

Net sales to the information technology and data communications market increased (approximately $234.0), driven primarily by strong sales growth to data center customers and market demand for storage and networking related products as customers worked to support higher demand for increased bandwidth to support work, school and entertainment activities during the pandemic, along with contributions from acquisitions.

New in FY2020

Net sales to the military market increased (approximately $32.2), driven by strength across multiple segments of the military market, offset in part by the impact of pandemic-related production disruptions experienced during the first half of the year.

New in FY2020

Net sales to the commercial aerospace market decreased significantly (approximately $135.3) primarily due to the significant impact of the COVID-19 pandemic on travel and aircraft production.

New in FY2020

Net sales to the mobile networks market decreased (approximately $98.5), which reflected the impact of the 2019 U.S. Government restrictions on certain Chinese customers as well as reduced demand from both mobile networks equipment manufacturers and mobile operators, partially as a result of the negative impact of the COVID-19 pandemic, offset in part by contributions from acquisitions.

New in FY2020

Net sales to the automotive market decreased (approximately $86.0), due to a significant reduction in demand resulting from customer factory shutdowns together with production disruptions in the first half of 2020 resulting from the COVID-19 pandemic, which was partially offset by a strong recovery of demand during the second half of the year.

New in FY2020

The decrease in net sales in the Cable Products and Solutions segment was largely driven by the

New in FY2020

negative impact of the COVID-19 pandemic primarily during the first half of 2020, as well as an overall weakness in market demand.

New in FY2020

The decrease in operating margin for the Interconnect Products and Assemblies segment for 2020 compared to 2019 was primarily driven by the significant incremental costs incurred, primarily during the first half of 2020, related to the COVID-19 pandemic.

New in FY2020

This decrease in the operating margin during the first half of 2020 was partly offset by strong operating leverage on higher sales volumes during the second half of 2020.

Coronavirus (“COVID-19”) Pandemic

New in FY2020

The COVID-19 pandemic has affected our manufacturing facilities throughout the world, as well as the facilities of our suppliers, customers and our customers’ contract manufacturers.

New in FY2020

Throughout most of 2020, particularly during the first half of the year, the COVID-19 pandemic has caused widespread disruptions to our Company, which have included and may continue to include, depending on the specific location, government regulations that limit our ability to operate certain of our facilities at full capacity 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.

New in FY2020

During the fourth quarter of 2020 and into 2021, in several regions around the world, including the United States and Europe, there has been a resurgence in COVID-19 cases.

New in FY2020

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, future government regulations and actions in response to the crisis, the timing, availability and effectiveness of vaccines, some of which have recently been approved and distributed for use, 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.

New in FY2020

In addition, the COVID-19 pandemic could impact the health of our management team and other employees.

New in FY2020

Given these uncertainties, we expect the pandemic to continue to have an impact on our operations, financial condition, liquidity and results of operations through at least the first half of 2021 and it could, potentially, extend for the full year and beyond.

New in FY2020

For a discussion of certain risks related to the COVID-19 pandemic, refer to the risk factor titled “We face significant risks related to adverse public health developments, including epidemics and pandemics such as the COVID-19 pandemic” in Part I, Item 1A.

Human Capital Management and Our Culture

New in FY2020

The Company’s success is based on the capability, adaptability and accountability of our people around the world.

New in FY2020

One of the key components of our business strategy is the fostering of a collaborative and entrepreneurial management culture.

New in FY2020

Each of our general managers operates in a flat organizational structure and is incented to grow and develop their business, with the support of the resources of the larger organization.

New in FY2020

We believe this structure, with approximately 120 general managers running unique businesses, creates an environment and culture where each of our employees has a more direct link to the success of their individual businesses and a more personal connection to the employees they oversee and the communities in which they operate.

New in FY2020

As of December 31, 2020, the Company had approximately 80,000 employees worldwide, with the majority of our people based in the Asia-Pacific region.

New in FY2020

_Governance and Culture_ - Our Board of Directors (the “Board”) is actively involved in overseeing the Company’s employee-related strategies and practices as well as the Company’s culture.

New in FY2020

This oversight is conducted both directly and through certain of the Board’s committees.

New in FY2020

At each of its regularly scheduled quarterly meetings, the Board reviews changes in key personnel and, at least annually, meets with management to discuss various human resources related topics, including talent development, succession planning, compensation and culture.

New in FY2020

We believe the Company’s culture has been a critical component of the Company’s success and reinforcing that culture is a key responsibility of our executive management.

New in FY2020

_Diversity and Inclusion_ - Our business spans the globe and the employees in our facilities reflect the diversity of our geographic footprint.

New in FY2020

The Company generally relies on local general management in every region, which we believe creates a strong degree of organizational stability and a deep commitment to our people and the local community.

Certain real estate

New in FY2020

The Company reviews its reporting unit structure each year or more frequently based on changes in our organization.

New in FY2020

In the third quarter of 2020, when testing for goodwill impairment, the Company performed a quantitative goodwill impairment assessment for each reporting unit.

New in FY2020

As part of the quantitative assessment, the Company estimated the fair value of each of its reporting units using a market approach.

New in FY2020

The Company believes the market-based guideline public company method provides the best indicator of fair value, by utilizing market prices and other relevant metrics for comparable publicly-traded companies with similar operating and investment characteristics, as well as recent transactions of similar businesses within the industry.

New in FY2020

Significant judgments, estimates and assumptions were used in the Company’s goodwill impairment assessment, including historical profitability data, the determination and selection of appropriate publicly-traded market comparison companies, and the calculation of comparable earnings-based and other multiples derived from comparable publicly traded companies and from recent transactions within the industry.

New in FY2020

As there are inherent uncertainties and management’s judgment related to impairment analyses, the Company evaluated whether there were reasonably likely changes to management’s estimates and assumptions that would have a material impact on the results of the goodwill impairment assessment.

New in FY2020

As of July 1, 2020, the Company determined that the fair value of each of the Company’s reporting units was substantially in excess of their respective carrying amounts, and therefore, no goodwill impairment resulted from the assessment.

New in FY2020

Company determines that it is more likely than not that the fair value of each of its reporting units is greater than its respective carrying amount.

New in FY2020

The expense incurred for stock-based compensation plans is included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Income.

New in FY2020

The accounting associated with each of the provisional amounts was completed in 2018.

New in FY2020

Noncontrolling Interests

New in FY2020

The Company presents noncontrolling interests in consolidated entities as its own caption within equity, separate from the Company’s equity attributable to Amphenol Corporation shareholders.

New in FY2020

Net income attributable to noncontrolling interests is classified below net income.

New in FY2020

Earnings per share is determined after the impact of the noncontrolling interests’ share in net income of the Company.

New in FY2020

The Company records each of its derivatives at fair value within the accompanying Consolidated Balance Sheets, and the respective accounting treatment for each derivative is based on its hedge designation.

New in FY2020

As of December 31, 2020, the Company does not have any significant concentration of exposure with any one counterparty.

New in FY2020

_Cash Flow Hedges_

New in FY2020

As of December 31, 2020 and 2019, the aggregate notional value of our outstanding cash flow hedge contracts was approximately $94 and $101, respectively.

New in FY2020

_Net Investment Hedges_

New in FY2020

The Company is exposed to variability in the U.S. dollar equivalent of the net investments in our foreign subsidiaries and, by extension, the U.S. dollar equivalent of any foreign earnings repatriated to the U.S. due to potential changes in foreign currency exchange rates.

Dropped from FY2019

For the year ended December 31, 2017, revenue from sales of the Company’s products was recognized at the time the goods were delivered, title passed and the risks and rewards of ownership passed to the customer, provided the earnings process was complete and revenue was measurable.

Dropped from FY2019

Such recognition generally occurred when the products reached the shipping point, the sales price was fixed and determinable, and collection was reasonably assured.

Dropped from FY2019

Delivery was determined by the Company’s shipping terms, which was primarily freight on board shipping point.

Dropped from FY2019

Revenue was recorded at the net amount to be received after deductions for estimated discounts, allowances and returns.

Since issuing Topic 842, the FASB has issued various subsequent ASUs, including but not limited to, ASU 2018-10, _Codification Improvements to Topic 842, Leases_, which clarified various aspects of the guidance under Topic 842, as well as ASU 2018-11, _Leases (Topic 842): Targeted Improvements_, which allows entities the option of recognizing the cumulative effect of applying Topic 842 as an adjustment to the opening balance of retained earnings in the year of adoption while continuing to present all prior periods under previous lease accounting guidance.

Dropped from FY2019

Prior to adoption, the Company evaluated Topic 842, including the initial review of any necessary changes to existing processes and systems that would be required to implement this standard, in order to determine its impact on our

Dropped from FY2019
