Employee engagement surveys are conducted annually to solicit, collect, and disseminate feedback in our effort to continually improve our work environment. Exponent maintains an online suggestion box for employees to express ideas for improving our work environment. Exponent also provides new parent affinity groups and a shared online workspace for balancing work and parenting life. Outreach In June of 2020, Exponent matched employee contributions to charities involved in diversity, equity, and inclusion initiatives with a $50,000 grant to the United Negro College Fund (UNCF). This grant will fund 16 scholarships for African American students pursuing STEM majors at UNCF-member historically black colleges and universities. We support the initiatives of our employees as they seek local service opportunities, and we are developing strategies for deeper engagement in service through our participation in professional societies. Our Volunteer Connection intranet site enables employees to share stories and pictures of outreach to their local communities and to encourage others to participate.

Risk Factors Exponent operates in a rapidly changing environment that involves a number of uncertainties, some of which are beyond our control and may have a material adverse effect on our financial condition and results of operations. These uncertainties include, but are not limited to, those mentioned elsewhere in this report and those set forth below. Although the risks are organized by headings, and each risk is discussed separately, many are interrelated. Risks Related to Our Clients and Demand for Our Services The effects of the COVID-19 pandemic have materially affected our operations and those of our clients. The duration and extent to which the COVID-19 pandemic will impact our future financial condition and results of operations remains uncertain. In March 2020, the World Health Organization declared the outbreak of COVID-19 a pandemic, which continues to spread throughout the U.S. and the world and has resulted in authorities implementing numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders, and business limitations and shutdowns. While we are unable to accurately predict the full impact that the COVID-19 pandemic will have on our financial condition and results of operations due to numerous uncertainties, including the duration and severity of the pandemic and containment measures, compliance with these measures has impacted, and will likely continue to impact, our operations. The vast majority of our employees have been working remotely since the implementation of government measures to contain the virus. These remote working arrangements may result in inefficiencies, delays and additional costs and risks. In addition, most of our clients are also working remotely, which may delay the initiation of new projects and the execution of on-going work. Many of our litigation support projects paused due to courthouse closures and associated legal delays. Travel restrictions have delayed work that requires inspection of a site or a product that cannot be shipped. The pandemic has also negatively impacted our ability to conduct user studies. The COVID-19 pandemic also raises the possibility of an extended global economic downturn and has caused volatility in financial markets, which could affect demand for our services and impact our financial condition and results of operations even after the pandemic is contained and the containment measures are lifted. For example, we 15 may be unable to collect receivables from those customers significantly impacted by the COVID-19 pandemic. We believe that our existing balances of cash, cash equivalents, short-term investments and cash generated from operations are sufficient to satisfy our working capital needs, capital expenditures, outstanding commitments, stock repurchases, dividends and other liquidity requirements over at least the next 12 months. However, we continue to monitor the impact of the COVID-19 pandemic on our cash flows and on the credit and financial markets. The duration and extent of the impact from the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the severity and transmission rate of the virus, the extent and effectiveness of containment actions, and the impact of these and other factors on our employees and clients. There can be no assurance, however, that the ultimate impact on our financial condition and results of operations will not be material. We will continue to evaluate the nature and extent of the impact of the COVID-19 pandemic to our business. The unpredictable and reactive nature of our business can create uneven performance in any given quarter or year. Revenues are primarily derived from services provided in response to client requests or events that occur without notice, and engagements, generally billed as services are performed, are terminable or subject to postponement or delay at any time by clients. As a result, backlog at any particular time is small in relation to our quarterly or annual revenues and is not a reliable indicator of revenues for any future periods. Revenues and operating margins for any particular quarter are generally affected by staffing mix, resource requirements and timing and size of engagements. Our financial results could suffer if our clients’ needs change more rapidly than we are able to secure the appropriate mix of trained, skilled and experienced personnel. As our clients’ needs change, new technologies develop, and legal and regulatory processes change, we may be unable to timely hire or train personnel with the appropriate new set of skills and experience which could negatively impact our growth and profitability. The loss of a large client could adversely affect our business. We currently derive a significant portion of our revenues from clients in the chemical, construction, consumer products, energy, life sciences and transportation industries. The loss of any large client could have a material adverse effect on our business, financial condition or results of operations. Our clients may be unable to pay for our services. If a client's financial difficulties become severe, the client may be unwilling or unable to pay our invoices in the ordinary course of business, which could adversely affect collections of both our accounts receivable and unbilled services. The COVID-19 pandemic raises the possibility of an extended global economic downturn, which may impact the ability of our customers to pay for our services. On occasion, some of our clients have entered bankruptcy, which has prevented us from collecting amounts owed to us. The bankruptcy of a client with substantial accounts receivable could have a material adverse effect on our financial condition and results of operations. Our business is dependent on our professional reputation. The professional reputation of Exponent and its consultants is critical to our ability to successfully compete for new client engagements and attract or retain professionals. Proven or unproven allegations against us may damage our professional reputation. Any factors that damage our professional reputation could have a material adverse effect on our business. Our business can be adversely impacted by deregulation or reduced regulatory enforcement. Public concern over health, safety and preservation of the environment has resulted in the enactment of a broad range of environmental and/or other laws and regulations by local, state and federal lawmakers and agencies. These laws and the implementation of new regulations affect nearly every industry, as well as the agencies of federal, state and local governments charged with their enforcement. To the extent changes in such laws, regulations and enforcement or other factors significantly reduce the exposures of manufacturers, owners, service providers and others to liability, the demand for our services may be significantly reduced. 16 Tort reform can reduce demand for our services. Several of our practices have a significant concentration in litigation support consulting services. To the extent tort reform reduces the exposure of manufacturers, owners, service providers and others to liability, the demand for our litigation support consulting services may be significantly reduced. Potential conflicts of interest may preclude us from accepting some engagements. We provide litigation support consulting and other services primarily in connection with significant disputes, or other matters that are usually adversarial or that involve sensitive client information. The nature of our consulting services has and will continue to preclude us from accepting engagements with other potential clients because of conflicts. Accordingly, the nature of our business limits the number of both potential clients and potential engagements. Inherent risks related to government contracts may adversely affect our business. We work for various United States and foreign governmental entities and agencies. Government entities reserve the right to audit our contracts and conduct inquiries and investigations of our business practices with respect to government contracts. Findings from an audit may result in fees being refunded to the government or prospective adjustment to previously agreed upon rates that will affect future margins. If a government client discovers improper or illegal activities in the course of audits or investigations, we may become subject to various civil and criminal penalties and administrative sanctions, which may include termination of contracts, forfeiture of profits, suspension of payments, fines and suspensions or debarment from doing business with other agencies of the government. The inherent limitations of internal controls may not prevent or detect all improper or illegal activities, regardless of the adequacy of such controls. Government contracts, and the proceedings surrounding them, are often subject to more extensive scrutiny and publicity than other commercial contracts. Negative publicity related to our government contracts, regardless of whether it is accurate, may further damage our business by affecting our ability to compete for new contracts. Governments may terminate, cancel, modify or curtail our contracts at any time prior to their completion. Under our government contracts, the client generally has the right not to exercise options to extend or expand our contracts and may otherwise terminate, cancel, modify or curtail our contracts at its convenience. Any decision by the client not to exercise contract options or to terminate, cancel, modify or curtail our programs or contracts would adversely affect our revenues, revenue growth and profitability. Risks Related to Our Operations Failure to attract and retain key employees may adversely affect our business. Exponent’s business involves the delivery of professional services and is labor-intensive. Our success depends in large part upon our ability to attract, retain and motivate highly qualified technical and managerial personnel. Qualified personnel are in great demand and are likely to remain a limited resource for the foreseeable future. We cannot provide any assurance that we can continue to attract sufficient numbers of highly qualified technical and managerial personnel and retain existing employees. We have experienced and expect to continue to experience employee turnover. The loss of key managerial employees, business generators or any significant number of employees could have a material adverse impact on our business, including our ability to secure and complete engagements. Our engagements may result in professional or other liability. Our services typically involve difficult engineering and scientific assignments and carry risks of professional and other liability. Many of our engagements involve matters that could have a severe impact on a client's business, cause a client to lose significant amounts of money, or prevent a client from pursuing desirable business opportunities. Accordingly, if a client is dissatisfied with our performance, the client could threaten or bring litigation in order to recover damages or to contest its obligation to pay our fees. Litigation alleging that we performed negligently, disclosed client confidential information, lost or damaged evidence, infringed on patents, were forced to withdraw from a legal matter due to a conflict or otherwise breached our obligations to a client could expose us to significant liabilities to our clients or other third parties or tarnish our reputation. 17 We are subject to unpredictable risks of litigation. Although we seek to avoid litigation whenever possible, from time to time we are party to various lawsuits and claims. Disputes may arise, for example, from employment issues, regulatory actions, business acquisitions and real estate and other commercial transactions. There can be no assurances that any lawsuits or claims will be immaterial in the future. Any material lawsuits or claims could adversely affect our business and reputation. We are subject to security breaches that may disrupt our operations and/or lead to the inability to protect confidential information. We have experienced, and expect to continue to be subjected to, security breaches and threats, none of which have been material to us to date. Despite the implementation of security and business continuity measures, our information technology infrastructure and networks are vulnerable to electronic breaches of security. Such breaches could lead to disruptions of our operations and potential unauthorized disclosure of confidential and/or personal information, which could result in legal claims or proceedings. While we have taken reasonable steps to prevent and mitigate the damage of a security breach by continuously improving our design and coordination of security controls across our business, those steps may not be effective and there can be no assurance that any such steps can be effective against all possible risks. Failure to protect client and employee data may have an adverse effect on our business. We manage, utilize, and store sensitive or confidential client or employee data, including personal data and protected health information. As a result, we are subject to numerous laws and regulations designed to protect this information, such as the U.S. federal and state laws governing the protection of health or other personally identifiable information, including the Health Insurance Portability and Accountability Act, and international laws such as the European Union General Data Protection Regulation. In addition, many states, U.S. federal governmental authorities and non-U.S. jurisdictions have adopted, proposed, or are considering adopting or proposing, additional data security and/or data privacy statutes or regulations such as the California Consumer Privacy Act. These laws and regulations are increasing in complexity and number. If any person, including any of our employees, negligently disregards or intentionally breaches our established controls with respect to client or employee data, or otherwise mismanages or misappropriates that data, we could be subject to significant monetary damages, regulatory enforcement actions, fines, and/or criminal prosecution. In addition, unauthorized disclosure of sensitive or confidential client or employee data, whether through systems failure, employee negligence, fraud, or misappropriation, could damage our reputation and cause us to lose clients and their related revenue in the future. Our remote working arrangements due to the COVID-19 pandemic may increase the risks associated with protecting client and employee data. Our international operations create special risks that could adversely affect our business. In addition to our offices in the United States, we have physical offices in the United Kingdom, Switzerland, Hong Kong, China, Singapore, Ireland, and Canada, and conduct business in several other countries. We expect to continue to expand globally and our international revenues may account for an increasing portion of our revenues in the future. Our international operations carry special financial, business and legal risks, including cultural and language differences; employment laws and related factors that could result in lower utilization, higher staffing costs, and cyclical fluctuations of utilization and revenues; currency fluctuations that adversely affect our financial position and operating results; burdensome regulatory requirements and other barriers to conducting business; tariffs/trade disputes and other trade barriers including the United Kingdom’s decision to leave the European Union; managing the risks associated with engagements with foreign officials and governmental agencies, including the risks arising from the United States Foreign Corrupt Practices Act and the United Kingdom Bribery Act of 2010; managing the risks associated with global privacy and data security laws and regulations including the General Data Protection Regulation in Europe; greater difficulties in managing and staffing foreign operations; successful entry and execution in new markets; restrictions on the repatriation of earnings; potentially adverse tax consequences; other impending legislation that could add additional risks to the business; and the COVID-19 pandemic and resulting restrictions on business activity, which vary significantly by region. 18 We could incur significant liabilities and suffer negative publicity if people or properties are harmed by the products and systems we sell or the services we offer. We, on occasion, design, develop, manufacture, sell, service and maintain various products and systems. In some instances, we also train operators of such products and systems. Many of these products and systems utilize software algorithms that are probabilistic in nature and subject to significant technical limitations. There are many factors, some of which are beyond our control, which could result in the failure of our products or systems. The failure of our products or systems could lead to injury, death, or extensive property damage and may lead to product liability, professional liability, or other claims against us. Further, if our products or systems fail, or are perceived to have failed, the negative publicity from such incident could have a material adverse effect on our business. General Risks Competition could reduce our pricing and adversely affect our business. The markets for our services are highly competitive. In addition, there are relatively low barriers to entry into our markets and we have faced, and expect to continue to face, additional competition from new entrants into our markets. Competitive pressure could reduce the market acceptance of our services and result in price reductions that could have a material adverse effect on our business, financial condition or results of operations. We hold substantial investments that could present liquidity risks. Our cash equivalent and short-term investment portfolio as of January 1, 2021 consisted primarily of obligations of the U.S. Treasury. We follow an established investment policy to monitor, manage and limit our exposure to interest rate and credit risk. The policy sets forth credit quality standards and limits our exposure to any one issuer, as well as our maximum exposure to various asset classes. Investments in some financial instruments may pose risks arising from liquidity and credit concerns. As of January 1, 2021, we had no impairment charge associated with our investment portfolio relating to such adverse financial market conditions. Although we believe our current investment portfolio has a low risk of impairment, we cannot predict future market conditions or market liquidity and can provide no assurance that our investment portfolio will remain unimpaired. Impairment of goodwill may require us to record a significant charge to earnings. On our balance sheet as of January 1, 2021, we have $8,607,000 of goodwill subject to periodic evaluation for impairment. Failure to achieve sufficient levels of cash flow at reporting units, the loss of key employees, changes to the scope of operations of our business or a significant and sustained decline in our stock price could result in goodwill impairment charges. During times of financial market volatility, significant judgment is required to determine the underlying cause of the decline and whether stock price declines are short-term in nature or indicative of an event or change in circumstances. Impairment of long-lived assets or restructuring activities may require us to record a significant charge to earnings. Our long-lived assets, including our office, laboratory and warehouse space in Menlo Park, California, our test and engineering center in Phoenix, Arizona, and our office and laboratory facilities in Natick, Massachusetts, are subject to periodic testing for impairment. Failure to achieve sufficient levels of cash flow at the asset group level could result in impairment of our long-lived assets. In addition, we have operating lease commitments for office and laboratory space. Changes in the business environment could lead to changes in the scope of operations of our business. These changes, including the closure of one or more offices, could result in restructuring and/or asset impairment charges. The COVID-19 pandemic raises the possibility of an extended global economic downturn, which increases the risk of long-lived asset impairment charges. 19 Changes in, or interpretations of, accounting principles could have a significant impact on our financial position and results of operations. We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These principles are subject to interpretation by the SEC and various bodies formed to interpret and create appropriate accounting principles. A change in these principles can have a significant effect on our reported results and may even retroactively affect previously reported transactions. Additionally, the adoption of new or revised accounting principles may require that we make significant changes to our systems, processes and controls. Our business can be adversely affected by downturns in the overall economy. The markets that we serve are cyclical and subject to general economic conditions. The direction and relative strength of the global economy continues to be uncertain. If economic growth in the United States, where we primarily operate, slows, our clients may consolidate or go out of business and thus demand for our services could be reduced significantly. Our quarterly results may vary. Variations in our revenues and operating results occur from time to time, as a result of a number of factors, such as the significance of client engagements commenced and completed during a quarter, the timing of engagements, the number of working days in a quarter, employee hiring and utilization rates, and integration of companies acquired. Because a high percentage of our expenses, particularly personnel and facilities related expenses, are relatively fixed in advance of any particular quarter, a variation in the timing of the initiation or the completion of our client assignments can cause significant variations in operating results from quarter to quarter. The market price of our common stock may be volatile. Many factors could cause the market price of our common stock to rise and fall. These include the risk factors listed above and below; changes in estimates of our performance or recommendations by securities analysts; future sales of shares of common stock in the public market; market conditions in the industry and economy as a whole; acquisitions or strategic alliances involving us or our competitors; restatement of financial results; and changes in accounting principles or methods. In addition, the stock market often experiences significant price fluctuations. These fluctuations are often unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the market price of our common stock. When the market price of a company's stock drops significantly, shareholders often institute securities class action litigation against that company. Any litigation against us could cause us to incur substantial costs, divert the time and attention of our management and other resources, or otherwise harm our business. There can be no assurance that we will continue to declare cash dividends or repurchase our shares at all or in any particular amounts. Our Board of Directors has declared quarterly dividends since March 2013. Our intent to continue to pay quarterly dividends and to repurchase our shares is subject to capital availability and, in the case of dividends, periodic determinations by our Board of Directors that cash dividends are in the best interest of our stockholders and are in compliance with all laws and agreements applicable to the declaration and payment of cash dividends by us. Future dividends and share repurchases may also be affected by, among other factors: our views on potential future capital requirements for investments, including acquisitions; legal risks; stock repurchase programs; changes in federal and state income tax laws or corporate laws; contractual restrictions; and changes to our business model. Our dividend payments and share repurchases may change from time to time, and we cannot provide assurance that we will continue to declare dividends or repurchase shares at all or in any particular amounts. A reduction or suspension in our dividend payments or share repurchase activity could have a negative effect on our stock price. 20 Catastrophic events may disrupt our business. We rely on our network infrastructure and certain third-party hosted services to support our operations. A disruption or failure of these systems in the event of a major earthquake, fire, flood, tsunami or other weather event, power loss, telecommunications failure, software or hardware malfunctions, pandemics, cyber-attack, war, terrorist attack or other catastrophic event that our disaster recovery plans do not adequately address, could have a material adverse effect on our business, financial condition or results of operations. Climate change may disrupt our business. The areas where we conduct business are vulnerable to the effects of climate change. For example, in California, wildfire danger increases the probability of planned power outages which may impact our employees’ abilities to commute to work and to stay connected. Climate-related events, including the increasing frequency of extreme weather events and their impact on critical infrastructure, have the potential to disrupt our business. Item 1B. Unresolved Staff Comments None. Item 2. Properties Our Silicon Valley office facilities consist of a 153,738 square foot building, with office and laboratory space located on a 6.3-acre tract of land we own in Menlo Park, California and an adjacent 27,000 square feet of warehouse storage space on a 1.1-acre tract of land that we also own. Our Test and Engineering Center (TEC) occupies 147 acres in Phoenix, Arizona. We lease this land from the state of Arizona under a 30-year lease agreement that expires in January 2028 and have options to renew for two fifteen-year periods. We constructed a 21,613 square foot indoor test facility as well as a 44,053 square foot engineering and test preparation building at the TEC. Our office facilities in Natick, Massachusetts, consist of a 60,480 square foot building, with office and laboratory space located on a 2.9 acre tract of land that we own and an adjacent building that consists of 9,100 square feet of office space located on a 0.81 acre tract of land that we also own. In addition, we lease office and laboratory space in 20 other locations in 13 states and the District of Columbia, as well as in China, Hong Kong, Singapore, Switzerland and the United Kingdom. Leases for these offices and laboratory facilities have terms generally ranging between one and ten years. Item 3. Legal Proceedings Exponent is not engaged in any material legal proceedings. Item 4. Mine Safety Disclosures Not applicable. 21 PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Exponent’s common stock is traded on the NASDAQ Global Select Market, under the symbol “EXPO.” As of February 19, 2021, there were 170 holders of record of our common stock. Because many of the shares of our common stock are held by brokers and other institutions on behalf of stockholders, we believe that there are considerably more beneficial holders of our common stock than record holders.

Management’s Discussion and Analysis of Financial Condition and Results of Operations OVERVIEW Exponent is an engineering and scientific consulting firm providing solutions to complex problems. Exponent's interdisciplinary organization of scientists, physicians, engineers, and business consultants draws from more than 90 technical disciplines to solve the most pressing and complicated challenges facing stakeholders today. The firm leverages over 50 years of experience in analyzing accidents and failures to advise clients as they innovate their technologically complex products and processes, ensure the safety and health of their users, and address the challenges of sustainability. CRITICAL ACCOUNTING ESTIMATES In preparing our consolidated financial statements, we make assumptions, judgments and estimates that can have a significant impact on our revenue, operating income and net income, as well as on the value of certain assets and liabilities on our consolidated balance sheet. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. On a regular basis we evaluate our assumptions, judgments and estimates and make changes accordingly. We believe that the assumptions, judgments and estimates involved in accounting for revenue recognition and estimating the allowance for contract losses and doubtful accounts have a potential impact on our consolidated financial statements, so we consider these to be our critical accounting policies. We discuss below the assumptions, judgments and estimates associated with these policies. Historically, our assumptions, judgments and estimates relative to our critical accounting policies have not differed materially from actual results. For further information on our critical accounting policies, see “Note 1: Summary of Significant Accounting Policies” of our Notes to Consolidated Financial Statements. Revenue recognition. We derive our revenues primarily from professional fees earned on consulting engagements, fees earned for the use of our equipment and facilities, as well as reimbursements for outside direct expenses associated with the services that are billed to our clients. Substantially all of our engagements are service contracts performed under time and material or fixed-price billing arrangements. For time and material and fixed-price service projects, revenue is generally recognized as the services are performed. For substantially all of our fixed-price service engagements, we recognize revenue based on the relationship of incurred labor hours at standard rates to our estimate of the total labor hours at standard rates we expect to incur over the term of the contract. Our estimate of total labor hours we expect to incur over the term of the contract is based on the nature of the project and our past experience on similar projects. We believe this methodology achieves a reliable measure of the revenue from the consulting services we provide to our customers under fixed-price contracts. Management judgments and estimates must be made and used in connection with the revenues recognized in any accounting period. These judgments and estimates include an assessment of the estimate as to the total effort required to complete fixed-price projects. Estimating the allowance for contract losses and doubtful accounts. We make estimates of our ability to collect accounts receivable and our unbilled but recognized work-in-process. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us or for disputes with customers that affect our ability to fully collect our accounts receivable and unbilled work-in-process, we record a specific allowance to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers we recognize allowances for contract losses and doubtful accounts taking into consideration factors such as historical write-offs, customer concentration, customer creditworthiness, current economic conditions, and aging of amounts due. 24 The following table sets forth, for the periods indicated, the percentage of revenues of certain items in our consolidated statements of income and the percentage increase (decrease) in the dollar amount of such items year to year: Percentage of Revenues for Fiscal Years 2020 2019 2018 Period to Period Change 2020 v 2019 2019 v 2018 Revenues ...................................................................... 100.0% 100.0% 100.0% (4.1)% 9.9% Operating expenses: Compensation and related expenses.......................

The decrease in revenues before reimbursements was due to a decrease in billable hours partially offset by an increase in billing rates. Business restrictions associated with the COVID-19 pandemic caused project delays across multiple areas of our business. Our litigation support work slowed with many projects paused due to court-related delays and closures. The business restrictions associated with the COVID-19 pandemic also delayed our human participant studies. The decrease in revenues before reimbursements was also due to fiscal 2020 having one less week of activity as compared to fiscal 2019. We continued to see strength in integrity management advisory services for the utilities sector as our clients focused on power reliability, in particular due to fire safety concerns in the western United States. We also experienced growth in our chemical regulation and food safety practice as our scientists evaluated the effects of chemicals and new products on human health and the environment. Society is raising the bar for safety, health, sustainability and reliability, and clients are increasingly seeking our interdisciplinary proactive solutions. We have been engaged by industry and government to help in the response to the coronavirus. We continue to advise clients with respect to disinfectant products and procedures, COVID-19 testing, contract tracing, and occupational health and safety. During the fourth quarter of 2020 we deployed wearable technology platforms for COVID-19 risk monitoring and mitigation for the U.S. Army and Navy. Net income was $82,552,000 during 2020 as compared to $82,460,000 during 2019. Diluted earnings per share increased to $1.55 for 2020 as compared to $1.53 for 2019. Net income and diluted earnings per share for 2020 benefited from a decrease in our effective tax rate due to an increase in the excess tax benefit associated with stock- based awards. The excess tax benefit associated with stock-based awards increased to $12,258,000 during 2020 as compared to $8,067,000 during 2019. We remain focused on selectively adding top talent and developing the skills necessary to expand upon our market position, providing clients with in-depth scientific research and analysis to determine what happened and how to prevent failures or exposures in the future. We also remain focused on capitalizing on emerging growth areas, managing other operating expenses, generating cash from operations, maintaining a strong balance sheet and undertaking activities such as share repurchases and dividends to enhance shareholder value. 25 COVID-19 Update We responded quickly and carefully to address the unprecedented challenges created by the pandemic. We have successfully adapted and will continue to evolve our business development, recruiting and operational approaches, yielding benefits both during and after this crisis. We have accelerated our sharing of in-depth scientific and regulatory knowledge through webinars and thought leadership pieces, which has fostered new client relationships and projects. We have shifted all recruiting activities online, allowing us to reach a more geographically expansive set of candidates. The health and safety of our team remain top priorities, and therefore we have leveraged our internal expertise to establish protocols that allow us to safely continue laboratory activities and resume human participant studies. Our business continuity plan and robust infrastructure have empowered productive remote work, and employees continue to work from home unless they are performing laboratory testing or inspections. Our leadership team has responded with enhanced internal communications to encourage increased connectivity across the firm. We are pleased that the Company has been able to address the majority of our clients’ needs with a mostly remote workforce. The relaxation of business restrictions in June allowed us to resume laboratory testing, inspections, and human participant studies for clients in non-essential industries. Field inspections of sites and products have increased due to lifting of travel restrictions but are still occurring at a reduced level since many businesses are not fully operational. We continue to receive new retentions for litigation support, and work is ongoing for many existing matters. At the same time, trial dates continue to be delayed, removing imminent deadlines and causing some clients – in particular the automotive industry – to pause work. Courts have been experimenting with virtual bench trials as well as social distancing for in-person trials, so we expect trials will gradually increase. We are pleased to be sharing our scientific and regulatory knowledge on health and safety issues related to the novel coronavirus through webinars and thought leadership pieces. We continue to advise clients with respect to disinfectant products and procedures, COVID-19 testing, contract tracing, and occupational health and safety. OVERVIEW OF THE YEAR ENDED JANUARY 1, 2021 Our revenues consist of professional fees earned on consulting engagements, fees for use of our equipment and facilities, and reimbursements for outside direct expenses associated with the services performed that are billed to our clients. We operate on a 52-53 week fiscal year with each year ending on the Friday closest to December 31st. The fiscal year ended January 1, 2021 included 52 weeks of activity. The fiscal year ended January 3, 2020 included 53 weeks of activity. The fiscal year ended December 28, 2018 included 52 weeks of activity. Fiscal 2021 is a 52 week fiscal year that will end on Friday, December 31, 2021. During 2020, billable hours decreased 7% to 1,273,000 as compared to 1,376,000 during 2019. Our utilization decreased to 67% for 2020 as compared to 72% for 2019. Technical full-time equivalent employees increased 1% to 912 for 2020 as compared to 901 for 2019. We continue to selectively hire key talent to expand our capabilities.

During 2020, billable hours for this segment decreased by 10% to 976,000 as compared to 1,084,000 during 2019. Utilization for this segment decreased to 67% for 2020 as compared to 73% for 2019. Business restrictions associated with the COVID-19 pandemic caused project delays across multiple practices within this segment. The most substantial impact was on our litigation support work with many projects paused due to court-related delays. The business restrictions associated with the COVID-19 pandemic also delayed our human participant studies. The decrease in billable hours was also due to fiscal 2020 having one less week of activity than fiscal 2019. We continued to see strength in integrity management advisory services for the utilities sector as our clients focus on power reliability, in particular due to fire safety concerns in the western United States. Technical full-time equivalent employees in this segment increased 1% to 704 during 2020 as compared to 699 for 2019. Clients continued to seek out our expertise for proactive and reactive engagements across a broad range of industries and use cases. Our multidisciplinary battery team leveraged its experience in consumer electronics to advance energy storage for electric vehicles and medical devices. Our integrity management advisory services for the utilities industry remained strong as clients and regulators focused on power reliability and safety. Our biomedical team advised clients as they navigated evolving regulatory frameworks around the world. The increase in revenues from our Environmental and Health segment was due to an increase in billable hours and an increase in billing rates partially offset by fiscal 2020 having one less week of activity than fiscal 2019. During 2020, billable hours for this segment increased by 2% to 297,000 as compared to 292,000 during 2019. The increase in billable hours was due to growth in our chemical regulation & food safety practice where we expanded our proactive services. The increase in billable hours was partially offset by fiscal 2020 having one less week of activity than fiscal 2019. This segment also experienced delays in litigation related projects due to business restrictions associated with the COVID-19 pandemic. Utilization for this segment increased to 69% during 2020 as compared to 68% during 2019. Technical full-time equivalents increased 3% to 208 during 2020 as compared to 202 for 2019 due to our recruiting and retention efforts. Revenues are primarily derived from services provided in response to client requests or events that occur without notice and engagements are generally terminable or subject to postponement or delay at any time by our clients. As a result, backlog at any particular time is small in relation to our quarterly or annual revenues and is not a reliable indicator of revenues for any future periods. Percent Change (0.9)% 2019 252,197 60.5% Compensation and Related Expenses (In thousands except percentages) Fiscal Years Compensation and related expenses................................................. $ Percentage of total revenues............................................................. 2020 250,041 $ 62.5% 27 The decrease in compensation and related expenses during 2020 was due to a change in the value of assets associated with our deferred compensation plan and a decrease in bonus expense, partially offset by an increase in payroll expense. During 2020, deferred compensation expense decreased $4,806,000 with a corresponding decrease to other income, net, as compared to the prior year due to the change in value of assets associated with our deferred compensation plan. This decrease consisted of an increase in the value of the plan assets of $8,028,000 during 2020 as compared to an increase in the value of the plan assets of $12,834,000 during 2019. During 2020, bonus expense decreased by $3,710,000 due to a corresponding decrease in the bonus pool, which is 33% of income before income taxes, interest income, bonus expense, and stock-based compensation. Payroll expense increased $6,187,000 during 2020 due to the increase in technical full-time equivalent employees and the impact of our annual salary increase, partially offset by fiscal 2020 having one less week of activity than fiscal 2019. We expect our compensation expense, excluding the change in value of deferred compensation plan assets, to increase as we selectively add new talent and adjust compensation to market conditions. Other Operating Expenses (In thousands except percentages) Fiscal Years 2020 2019 Percent Change Other operating Expenses................................................................. $ Percentage of total revenues............................................................. 32,234 $ 8.1% 33,562 8.0% (4.0)% Other operating expenses include facilities-related costs, technical materials, computer-related expenses and depreciation and amortization of property, equipment and leasehold improvements. The decrease in other operating expenses was primarily due to a decrease in occupancy expense of $978,000 and a decrease in technical materials of $487,000. The decrease in occupancy expenses and technical materials were primarily due to COVID-19 pandemic- related business restrictions and fiscal 2020 having one less week of activity than fiscal 2019. We expect other operating expense to grow as we selectively add new talent and make additional investments in our corporate infrastructure. Reimbursable Expenses (In thousands except percentages) Fiscal Years 2020 2019 Percent Change Reimbursable expenses .................................................................... $ Percentage of total revenues............................................................. 21,488 $ 5.4% 25,809 6.2% (16.7)% The amount of reimbursable expenses will vary from year to year depending on the nature of our projects. The decrease during 2020 was primarily due to COVID-19 pandemic-related business and travel restrictions. General and Administrative Expenses (In thousands except percentages) Fiscal Years 2020 2019 Percent Change General and administrative expenses ............................................... $ Percentage of total revenues............................................................. 12,888 $ 3.2% 20,520 4.9% (37.2)% 28 The decrease in general and administrative expenses during 2020 was primarily due to decreases in travel and meals of $5,969,000 and a decrease in personnel expenses of $1,348,000. The decrease was also due to fiscal 2020 having one less week of activity than fiscal 2019. The decrease in travel and meals and personnel expenses were primarily due to COVID-19 pandemic-related business and travel restrictions. We expect general and administrative expenses to increase as we selectively add new talent, expand our business development efforts, and pursue staff development initiatives.

The decrease in revenues was due to a decrease in billable hours, partially offset by an increase in billing rates. Business restrictions associated with the COVID-19 pandemic caused project delays across multiple practices within this segment. The most substantial impact was on our litigation support work with many projects paused due to court-related delays. The business restrictions associated with the COVID-19 pandemic also delayed our human participant studies. The decrease in billable hours was also due to fiscal 2020 having one less week of activity than fiscal 2019. We continued to see strength in the integrity management advisory services for the utilities sector. The impact of the decrease in revenues to operating income for this segment was partially offset by a decrease in operating expenses primarily due to the business and travel restrictions associated with the COVID-19 pandemic. The slight increase in operating income for our Environmental and Health segment during 2020 as compared to 2019 was due to an increase in revenues. The increase in revenues was due to an increase in billable hours and an increase in billing rates, partially offset by fiscal 2020 having one less week of activity than fiscal 2019. The increase in billable hours was due to growth in our chemical regulation & food safety practice where we expanded our proactive services. Certain operating expenses are excluded from the Company’s measure of segment operating income. These expenses include the costs associated with our human resources, finance, information technology, and business development groups; the deferred compensation expense/benefit due to the change in value of assets associated with our deferred compensation plan; stock-based compensation associated with restricted stock unit and stock option awards; and the change in our allowance for contract losses and doubtful accounts. The decrease in corporate operating expenses during 2020 as compared to 2019 was primarily due to a decrease in deferred compensation expense. During 2020, deferred compensation expense decreased $4,806,000, with a corresponding decrease to other income, net, as compared to the prior year, due to the change in value of assets associated with our deferred compensation plan. This decrease consisted of an increase in the value of plan assets of $8,028,000 during 2020 as compared to an increase in the value of plan assets of $12,834,000 during 2019. The decrease in corporate operating expenses was also due to a decrease in travel and meals and personnel expenses primarily due to COVID-19 pandemic-related business and travel restrictions. The decrease was also due to fiscal 2020 having one less week of activity than fiscal 2019. Other Income (In thousands except percentages) Fiscal Years 2020 2019 Percent Change Other income .................................................................................... $ Percentage of total revenues............................................................. 13,687 $ 3.4% 19,079 4.6% (28.3)% 29 Other income consists primarily of interest income earned on available cash, cash equivalents and short-term investments, changes in the value of assets associated with our deferred compensation plan and rental income from leasing excess space in our Silicon Valley facility. The decrease in other income was primarily due to the change in value of assets associated with our deferred compensation plan and a decrease in interest income of $2,207,000, partially offset by an increase in the realized gain on foreign exchange of $1,432,000 and an increase in rental income of $210,000. During 2020, other income decreased $4,806,000 with a corresponding decrease to deferred compensation expense as compared to 2019, due to the change in value of assets associated with our deferred compensation plan. This change consisted of an increase in the value of the plan assets of $8,028,000 during 2020 as compared to an increase in the value of the plan assets of $12,834,000 during 2019. The decrease in interest income was due to lower interest rates for our cash equivalents and short-term investments. The increase in the realized gain on foreign exchange was due to an increase in the value of monetary assets denominated in non-functional currencies during 2020 and the recognition of a foreign currency exchange loss of $601,000 during 2019 associated with the divestiture of our German subsidiary.

The excess tax benefit associated with stock-based awards increased to $12,258,000 during 2020 as compared to $8,067,000 during 2019. During 2019 we recognized a tax charge of $956,000 associated with the divestiture of our German subsidiary.

During 2019, billable hours for this segment increased by 9.3% to 1,084,000 as compared to 992,000 during 2018. This segment had strong growth in its biomedical engineering, buildings & structures, construction consulting, human factors, materials & corrosion engineering, thermal sciences, and polymer science & materials chemistry practices. We continued to see strong demand from multinational companies for our scientific expertise and advice regarding their products. Safety concerns regarding energy storage systems drove increased demand for risk assessments in the consumer products, transportation, utility and medical device industries. The increase in billable hours was also due to fiscal 2019 having one additional week of activity than fiscal 2018. Utilization decreased to 73% for 2019 as compared to 75% for 2018. The decrease in utilization was due to the completion of a large human factors’ assessment in the third quarter of 2018. Technical full-time equivalents increased 9.2% to 699 for 2019 as compared to 640 for 2018 due to our recruiting and retention efforts. 30 The increase in revenues from our Environmental and Health segment was due to an increase in billable hours and an increase in billing rates. During 2019, billable hours for this segment increased by 3.5% to 292,000 as compared to 282,000 during 2018. The increase in billable hours was due to growth in our chemical regulation and food safety practice where we expanded our proactive services. The increase in billable hours was also due to fiscal 2019 having one additional week of activity than fiscal 2018. Utilization was 68% for both 2019 and 2018. Technical full-time equivalents increased 1.5% to 202 during 2019 as compared to 199 for 2018 due to our recruiting and retention efforts. Revenues are primarily derived from services provided in response to client requests or events that occur without notice and engagements are generally terminable or subject to postponement or delay at any time by our clients. As a result, backlog at any particular time is small in relation to our quarterly or annual revenues and is not a reliable indicator of revenues for any future periods.

During 2019, payroll and fringe benefits increased $13,629,000 and $1,735,000, respectively, due to the increase in technical full-time equivalent employees, the impact of our annual salary increase, and fiscal 2019 having one additional week of activity than fiscal 2018. During 2019, bonus expense increased by $4,576,000 due to a corresponding increase in income before income taxes, before bonus expense, and before stock-based compensation. During 2019, deferred compensation expense increased $16,734,000 with a corresponding increase to other income, net, as compared with the prior year due to the change in value of assets associated with our deferred compensation plan. This increase consisted of an increase in the value of the plan assets of $12,834,000 during 2019 as compared to a decrease in the value of the plan assets of $3,900,000 during 2018.

The increase in other operating expenses was primarily due to an increase in occupancy expense of $1,028,000, an increase in information technology expenses of $768,000, an increase in depreciation and amortization of $514,000, and an increase in technical materials of $317,000. These increases were due to our increase in technical full-time equivalent employees, investments in our corporate infrastructure and fiscal 2019 having one additional week of activity than fiscal 2018. Reimbursable Expenses (In thousands except percentages) Fiscal Years 2019 2018 Percent Change Reimbursable expenses .................................................................... $ Percentage of total revenues............................................................. 25,809 $ 6.2% 24,884 6.6% 3.7% 31 The amount of reimbursable expenses will vary from year to year depending on the nature of our projects. General and Administrative Expenses (In thousands except percentages) Fiscal Years 2019 2018 Percent Change General and administrative expenses ............................................... $ Percentage of total revenues............................................................. 20,520 $ 4.9% 17,532 4.6% 17.0% The increase in general and administrative expenses during 2019 was primarily due to an increase in travel and meals of $1,724,000, an increase in marketing and promotion of $334,000, an increase in bad debt of $259,000 and several other individually insignificant increases. The increase in travel and meals was due to a firm-wide managers meeting held during 2019, an increase in technical full-time equivalent employees, an increase in business development and professional development activities and fiscal 2019 having one additional week of activity than fiscal 2018. The increase in marketing and promotion was due to an increase in business development activities. Operating Income (In thousands except percentages) Engineering and other scientific ....................................................... $ Environmental and health .................................................................

The increase in revenues was due to an increase in billable hours and an increase in billing rates. We continued to see strong demand for our services related to product recalls, including assignments from the consumer products and automotive industries. Proactive services continued to expand as companies sought our interdisciplinary advice throughout the product life cycle, consistent with the increased importance placed on understanding how users interact with complex technologies. The increase in operating income for our Environmental and Health segment during 2019 as compared to 2018 was due to an increase in revenues. The increase in revenues was due to an increase in billable hours and an increase in billing rates. The increase in billable hours was due to the expansion of our chemical regulation & food safety proactive services. Certain operating expenses are excluded from the Company's measure of segment operating income. These expenses include the costs associated with our human resources, finance, information technology, and business development groups; the deferred compensation expense/benefit due to the change in value of assets associated with our deferred compensation plan; stock-based compensation associated with restricted stock unit and stock option awards; and the change in our allowance for contract losses and doubtful accounts. The increase in corporate operating expenses during 2019 as compared to 2018 was primarily due to an increase in deferred compensation expense. During 2019, deferred compensation expense increased $16,734,000, with a corresponding increase to other income, net, as compared to the prior year, due to the change in value of assets associated with our deferred compensation plan. This increase consisted of an increase in the value of plan assets of $12,834,000 during 2019 as compared to a decrease in the value of plan assets of $3,900,000 during 2018. The increase in corporate operating expenses was also due to an increase in travel and meals due to a firm-wide managers meeting held during 2019, an increase in stock-based compensation associated with restricted stock unit grants, and increases in expenses for our human resources, finance, information technology, and business development groups due to increases in technical full-time equivalent employees, investments in our corporate infrastructure and fiscal 2019 having one additional week of activity than fiscal 2018. 32 Other Income (In thousands except percentages) Engineering and other scientific ....................................................... $ Environmental and health ................................................................. Fiscal Years 2019 110,822 $ 26,589 2018 100,307 23,824 Percent Change 10.5% 11.6% Other income consists primarily of interest income earned on available cash, cash equivalents and short-term investments, changes in the value of assets associated with our deferred compensation plan and rental income from leasing excess space in our Silicon Valley facility. The increase in other income was primarily due to the change in value of assets associated with our deferred compensation plan and an increase in interest income, partially offset by an increase in loss on foreign exchange. During 2019, other income increased $16,734,000 with a corresponding increase to deferred compensation expense as compared to 2018. This change consisted of an increase in the value of the plan assets of $12,834,000 during 2019 as compared to a decrease in the value of the plan assets of $3,900,000 during 2018. The increase in interest income of $1,161,000 was due to higher average balances and higher interest rates for our cash equivalents and short-term investments. During 2019, we recognized a foreign currency exchange loss of $601,000 associated with the planned divestiture of our German subsidiary. Income Taxes (In thousands except percentages) Fiscal Years Income taxes..................................................................................... $ Percentage of total revenues.............................................................

The excess tax benefit associated with stock-based awards increased to $8,067,000 during 2019 as compared to $4,154,000 during 2018. During 2019, we recognized a tax charge of $956,000 associated with the planned divestiture of our German subsidiary. LIQUIDITY AND CAPITAL RESOURCES (In thousands) Net cash provided by (used in): Operating activities ........................................................................... $ Investing activities ............................................................................ $ Financing activities ........................................................................... $ 2020 Fiscal Years 2019 2018 103,312 $ 5,024 $ (88,355) $ 108,059 $ 4,269 $ (63,414) $ 91,188 (25,820) (62,500) We financed our business in 2020 through available cash and cash flows from operating activities. We invest our excess cash in cash equivalents and short-term investments. As of January 1, 2021, our cash, cash equivalents and short-term investments were $242,526,000 as compared to $231,601,000 at January 3, 2020. We believe our existing balances of cash, cash equivalents and short-term investments will be sufficient to satisfy our working capital needs, capital expenditures, outstanding commitments, stock repurchases, dividends and other liquidity requirements over at least the next 12 months. Generally, our net cash provided by operating activities is used to fund our day-to-day operating activities. First quarter operating cash requirements are generally higher due to payment of our annual bonuses accrued during the prior year. Our largest source of operating cash flows is cash collections from our clients. Our primary uses of cash from operating activities are for employee-related expenditures, leased facilities, taxes, and general operating expenses. Net cash provided by operating activities was $103.3 million for 2020 as compared to $108.1 million and $91.2 million in 2019 and 2018, respectively. 33 During 2020, 2019 and 2018, net cash provided by/used in investing activities was primarily related to the purchase and maturity of short-term investments and capital expenditures. During 2019 we substantially completed construction of our office and laboratory facilities in Natick, Massachusetts. Total capital expenditures associated with this facility were $15.2 million during 2019. During 2018, we purchased 2.9 acres of land in Natick, Massachusetts, and started construction of our office and laboratory facilities. The total purchase price for the land was $5.2 million and our total capital expenditures during 2018 associated with the construction were $5.3 million. The increase in net cash used in financing activities during 2020 as compared to 2019 was due to an increase in our quarterly dividend payment and an increase in repurchases of our common stock. The increase in net cash used in financing activities during 2019 as compared to 2018 was due to an increase in our quarterly dividend payment partially offset by a decrease in repurchases of our common stock. We expect to continue our investing activities, including capital expenditures. Furthermore, cash reserves may be used to repurchase common stock under our stock repurchase programs, pay dividends, procure facilities and equipment or strategically acquire professional service firms that are complementary to our business.

Refer to “Note 7: Income Taxes” of the Notes to Consolidated Financial Statements for additional discussion on unrecognized tax benefits. We maintain nonqualified deferred compensation plans for the benefit of a select group of highly compensated employees. Vested amounts due under the plans of $83,961,000 were recorded as a long-term liability on our consolidated balance sheet at January 1, 2021. Vested amounts due under the plans of $5,016,000 were recorded as a current liability on our consolidated balance sheet at January 1, 2021. Company assets that are earmarked to pay benefits under the plans are held in a rabbi trust and are subject to the claims of our creditors. As of January 1, 2021, invested amounts under the plans of $83,731,000 were recorded as a long-term asset on our consolidated balance sheet. As of January 1, 2021, invested amounts under the plans of $5,016,000 were recorded as a current asset on our consolidated balance sheet. As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was serving, at our request in such capacity. The indemnification period covers all pertinent events and occurrences during the officer’s or director’s lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have director and officer insurance coverage that reduces our exposure and enables us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal. Off-Balance Sheet Arrangements As part of our ongoing business, we do not engage in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities. 34 Non-GAAP Financial Measures Regulation G, conditions for use of Non-Generally Accepted Accounting Principles (“Non-GAAP”) financial measures, and other SEC regulations define and prescribe the conditions for use of certain Non-GAAP financial information. Generally, a Non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. We closely monitor two financial measures, EBITDA and EBITDAS, which meet the definition of Non-GAAP financial measures. We define EBITDA as net income before income taxes, interest income, depreciation and amortization. We define EBITDAS as EBITDA before stock-based compensation. We regard EBITDA and EBITDAS as useful measures of operating performance and cash flow to complement operating income, net income and other GAAP financial performance measures. Additionally, management believes that EBITDA and EBITDAS provide meaningful comparisons of past, present and future operating results. These measures are used to evaluate our financial results, develop budgets and determine employee compensation. These measures, however, should be considered in addition to, and not as a substitute or superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP. A reconciliation of the Non-GAAP measures to the nearest comparable GAAP measure is set forth below. The following table shows EBITDA as a percentage of revenues before reimbursements for 2020, 2019 and 2018: (in thousands, except percentages) Revenues before reimbursements..................................................... $ EBITDA ........................................................................................... $ EBITDA as a % of revenues before reimbursements ...................... 2020 378,412 102,102 $ $ 27.0% Fiscal Years 2019 391,390 107,084 $ $ 27.4% 2018 354,639 96,858 27.3% The decrease in EBITDA as a percentage of revenues before reimbursements for 2020 as compared to 2019 was due to a 3% decrease in revenues before reimbursements, partially offset by a 37% decrease in general and administrative expenses primarily due to the business and travel restrictions associated with the COVID-19 pandemic. The slight increase in EBITDA as a percentage of revenues before reimbursements for 2019 as compared to 2018 was due to 10% growth in revenues before reimbursements, partially offset by a 17% increase in general and administrative expenses primarily due to a firm-wide managers’ meeting during 2020.

Quantitative and Qualitative Disclosure about Market Risk Exponent is exposed to interest rate risk associated with our balances of cash, cash equivalents and short-term investments. We manage our interest rate risk by maintaining an investment portfolio primarily consisting of debt instruments with high credit quality and relatively short average effective maturities in accordance with the Company’s investment policy. The maximum effective maturity of any issue in our portfolio of cash equivalents and short-term investments is 3 years and the maximum average effective maturity of the portfolio cannot exceed 12 months. If interest rates were to instantaneously increase or decrease by 100 basis points, the change in the fair value of our portfolio of cash equivalents and short-term investments would not have a material impact on our financial statements. We do not use derivative financial instruments in our investment portfolio. Notwithstanding our efforts to manage interest rate risk, there can be no assurances that we will be adequately protected against the risks associated with interest rate fluctuations. We have foreign currency risk related to our revenues and expenses denominated in currencies other than the U.S. dollar, primarily the British Pound, the Chinese Yuan, and the Hong Kong Dollar. Accordingly, changes in exchange rates may negatively affect the revenues and net income of our foreign subsidiaries as expressed in U.S. dollars. At January 1, 2021, we had net assets of approximately $16.9 million with a functional currency of the British Pound, net assets of approximately $5.9 million with a functional currency of the Chinese Yuan, and net assets of approximately $5.5 million with a functional currency of the Hong Kong Dollar associated with our operations in the United Kingdom, China, and Hong Kong respectively. We also have foreign currency risk related to foreign currency transactions and monetary assets and liabilities denominated in currencies that are not the functional currency. We have experienced and will continue to experience fluctuations in our net income as a result of gains (losses) on these foreign currency transactions and the re- measurement of monetary assets and liabilities. At January 1, 2021, we had net assets denominated in the non- functional currency of approximately $6.5 million. We do not use foreign exchange contracts to hedge any foreign currency exposures. To date, the impacts of foreign currency exchange rate changes on our consolidated revenues and consolidated net income have not been material. However, our continued international expansion increases our exposure to exchange rate fluctuations and as a result such fluctuations could have a significant impact on our future results of operations. 36 Item 8. Financial Statements and Supplementary Data See Item 15 of this Annual Report on Form 10-K for required financial statements and supplementary data. Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures KPMG LLP, an independent registered public accounting firm, has audited the internal control over financial reporting of Exponent, Inc., as stated in their report which is included in Part IV, Item 15 of this Annual Report on Form 10-K. (a) Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13(a)-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Annual Report on Form 10-K. (b) Management’s Report on Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting is designed to provide reasonable assurance, but not absolute assurance, regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. generally accepted accounting principles. There are inherent limitations to the effectiveness of any system of internal control over financial reporting. These limitations include the possibility of human error, the circumvention or overriding of the system and reasonable resource constraints. Because of its inherent limitations, our internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control - Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective at the reasonable assurance level as of January 1, 2021. (c) Changes in Internal Control Over Financial Reporting. There have not been any changes in the Company’s internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act, during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

We also have audited the Company’s internal control over financial reporting as of January 1, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of January 1, 2021 and January 3, 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended January 1, 2021, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of January 1, 2021 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Change in Accounting Principle As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for leases as of December 29, 2018 due to the adoption of FASB Accounting Standards Codification Topic 842, Leases. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting 40 includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Collectibility of accounts receivable As discussed in Notes 1 and 6 to the consolidated financial statements, the Company’s allowance for contract losses and doubtful accounts was $4.0 million as of January 1, 2021. The Company’s accounts receivable, net was $111.6 million as of January 1, 2021 which represents 19% of total assets and 28% of revenue for the year ended January 1, 2021. As discussed in Note 1, the Company maintains allowances to estimate their ability to collect financial obligations from customers. The Company records a specific allowance in circumstances where the Company is aware of a dispute with a specific customer or a specific customer’s inability to meet its financial obligations. We identified the assessment of the collectibility of accounts receivable as a critical audit matter. Specifically, the specific allowance is an estimate which involves assessing the likelihood of collection of a customer’s accounts receivable by considering various factors such as nature of the dispute, communications from the customer, historical collections, and number of days accounts receivables have been outstanding. Subjective auditor judgment was involved in evaluating the relevance and reliability of the evidence obtained in evaluating these factors. The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the critical audit matter. This included controls related to the Company’s assessment of the specific allowance. We investigated significant fluctuations in the specific allowance as compared to gross accounts receivable and the prior year specific allowance. For a selection of customer invoices and projects, we inquired of Company personnel to evaluate the rationale for establishing a specific allowance for certain customers and assessed the Company’s estimate of the specific customer allowance by evaluating the underlying contractual documents, historical collection trends, communications with customers, number of days accounts receivable have been outstanding, and other additional factors. We also evaluated subsequent collections occurring after the balance sheet date for the selected customer invoices and projects and considered the impact of potential subsequent events on the estimate of the specific customer allowance. /s/ KPMG, LLP We have served as the Company’s auditor since 1987.

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company operates on a 52-53 week fiscal year with each year ending on the Friday closest to December 31st. Fiscal period 2020 included 52 weeks of activity and ended on January 1, 2021. Fiscal period 2019 included 53 weeks of activity and ended on January 3, 2020. Fiscal period 2018 included 52 weeks of activity and ended on December 28, 2018. Fiscal period 2021 is 52 weeks and will end on December 31, 2021. Stock Split On May 31, 2018, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to (i) increase the number of authorized shares of common stock to 120,000,000 and (ii) effect a two-for-one stock split. As a result of the stock split, each shareholder of record at the close of business on May 31, 2018, received one additional share of common stock for each share of common stock owned by such stockholder. Restricted stock unit awards and stock option awards have also been adjusted to reflect the two-for-one stock split. For periods prior to the stock split, all share and per share data in the Company’s consolidated financial statements and related notes have been retroactively adjusted to reflect the stock split. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Estimates are used for, but not limited to, revenue recognition, allowance for contract losses and doubtful accounts, stock-based compensation, income taxes, goodwill, the useful life of property, equipment and leasehold improvements, and operating lease liabilities. Actual results could differ from those estimates. Foreign Currency Translation The Company translates the assets and liabilities of foreign subsidiaries, whose functional currency is the local currency, at exchange rates in effect at the balance sheet date. Revenues and expenses are translated at the average rates of exchange prevailing during the year. The adjustment resulting from translating the financial statements of such foreign subsidiaries is included in accumulated other comprehensive income/(loss), which is reflected as a separate component of stockholders’ equity. Cash Equivalents Cash equivalents consist of highly liquid investments such as money market mutual funds, commercial paper and debt securities with original remaining maturities of three months or less from the date of purchase. Short-term Investments Short-term investments consist of debt securities classified as available-for-sale and are carried at their fair value as of the balance sheet date. Short-term investments generally mature between three months and three years from the purchase date. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent investments readily available for current operations. 47 The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income. Realized gains or losses are determined on the specific identification method and are reflected in other income. Net unrealized gains and losses are recorded directly in accumulated other comprehensive income/(loss) except for unrealized losses that are deemed to be other-than-temporary, which are reflected in net income. Investments are reviewed on a regular basis to evaluate whether or not any security has experienced an other-than temporary decline in fair value. When assessing investments for other-than-temporary declines in fair value, the Company considers the significance of the decline in value as a percentage of the original cost, how long the market value of the investment has been less than its original cost, any news that has been released specific to the investee, and the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis. Allowances for Contract Losses and Doubtful Accounts The Company maintains allowances for estimated losses resulting from the inability of customers to meet their financial obligations or for disputes that affect the Company’s ability to fully collect amounts due. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations or aware of a dispute with a specific customer, a specific allowance is recorded to reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers the Company recognizes allowances for doubtful accounts based upon historical write-offs, customer concentration, customer creditworthiness, current economic conditions, aging of amounts due and changes in customer payment terms. Property, Equipment and Leasehold Improvements Property, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are recognized using the straight-line method. Buildings are depreciated over their estimated useful lives ranging from thirty to forty years. Equipment is depreciated over its estimated useful life, which generally ranges from two to seven years. Leasehold improvements are amortized over the shorter of their estimated useful lives, generally seven years, or the term of the related lease. Impairment of Long-Lived Assets The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future undiscounted cash flows to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company has not recognized impairment losses on any long-lived assets in 2020, 2019 or 2018. Goodwill The Company assesses the impairment of goodwill annually and whenever events or changes in circumstances indicate that the carrying amount may be impaired. The Company’s annual goodwill impairment review is completed during the fourth quarter of each year. The Company evaluates goodwill for each reporting unit for impairment by assessing qualitative factors to determine whether it is necessary to perform a quantitative goodwill impairment test. The Company considers events and circumstances, including but not limited to, macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers, a change in the composition or carrying amount of a reporting unit’s net assets and changes in the price of its common stock. If, after assessing the totality of events or circumstances, the Company determines that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then the quantitative goodwill impairment test is not performed. 48 The Company completed its annual assessment for all reporting units with goodwill for 2020 and determined, after assessing the totality of the qualitative factors, that it is more likely than not that the fair value of each reporting unit is greater than its respective carrying amount. Accordingly, there was no indication of impairment of goodwill for any of the Company’s reporting units and the quantitative goodwill impairment test was not performed. The Company did not recognize any goodwill impairment losses in 2020, 2019 or 2018. Deferred Revenues Deferred revenues represent amounts billed to clients in advance of services provided. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis and the financial reporting basis of assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates and laws in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities from changes in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. An uncertain tax position is recognized if it is determined that it is more likely than not to be sustained upon examination. The tax position is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits as income tax expense. Accrued interest and penalties are insignificant at January 1, 2021 and January 3, 2020. Fair Value of Financial Instruments Financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, other assets and accounts payable. Cash, cash equivalents and short-term investments are recorded at fair value. The carrying amount of the Company’s accounts receivable, other assets and accounts payable approximates their fair values due to their short maturities. Stock-Based Compensation Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period of the entire award. The Company accounts for forfeitures of stock-based awards when they occur. Net Income Per Share Basic per share amounts are computed using the weighted-average number of common shares outstanding during the period. Dilutive per share amounts are computed using the weighted-average number of common shares outstanding and potentially dilutive securities, using the treasury stock method if their effect would be dilutive. The following schedule reconciles the denominators of the Company’s calculation for basic and diluted net income per share: (In thousands) Shares used in basic per share computation......................................

There were no equity awards excluded from the diluted per share calculation for 2019 and 2018. 49 Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) established Topic 326, Measurement of Credit Losses on Financial Instruments, by issuing Accounting Standard Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement of the expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost where there is a contractual right to receive cash, including, accounts receivables, loan receivables and held-to-maturity debt securities. The Company adopted ASU No. 2016-13 in the first quarter of 2020 and the impact of the adoption was not material to the Company’s consolidated financial statements. In February 2016, the Financial Accounting Standards Board (“FASB”) established Topic 842, Leases, by issuing Accounting Standards Update (“ASU”) No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted the ASU as of the beginning of its first quarter of 2019. A modified retrospective transition approach is required, requiring the application of the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. The Company adopted the new standard on December 29, 2018, using the effective date as the date of initial application. Consequently, financial information was not updated and the disclosures required under the new standard were not provided for dates and periods before December 29, 2018. The new standard provides a number of optional practical expedients in transition. The Company elected the ‘package of practical expedients’, which permits it not to reassess under the new standard prior conclusions about lease identification, lease classification and initial direct costs. The Company elected the practical expedient to include both lease and non-lease components as a single component and account for it as a lease for all asset classes. The Company also elected to apply the short-term lease exception for all leases. Under the short-term lease exception, the Company will not recognize ROU assets or lease liabilities for leases that, at the acquisition date, have a remaining lease term of 12 months or less. The ASU had a material impact to the Company’s consolidated balance sheet, but did not have an impact on its consolidated statement of income. The most significant impact was the recognition of ROU assets and lease liabilities for its operating leases. Recently Accounting Pronouncements Not Yet Effective There are no new accounting pronouncements that have significance, or potential significance, to the Company’s consolidated financial statements. Note 2: Revenue Recognition Substantially all of the Company’s engagements are performed under time and materials or fixed-price arrangements. For time and materials contracts, the Company utilizes the practical expedient under Accounting Standards Codification 606 – Revenue from Contracts with Customers, which states, if an entity has a right to consideration from a customer in an amount that corresponds directly with the value of the entity’s performance completed to date (for example, a service contract in which an entity bills a fixed amount for each hour of service provided), the entity may recognize revenue in the amount to which the entity has a right to invoice. 50 The following table discloses the percent of the Company’s revenue generated from time and materials contracts: Engineering & other scientific .................................................. Environmental and health.......................................................... Total time and materials revenues ....................................... 2020 61% 19% 80% Fiscal Years 2019 66% 18% 84% 2018 64% 18% 82% For fixed-price contracts the Company recognizes revenue over time because of the continuous transfer of control to the customer. The customer typically controls the work in process as evidenced either by contractual termination clauses or by the Company’s rights to payment for work performed to date to deliver services that do not have an alternative use to the Company. Revenue for fixed-price contracts is recognized based on the relationship of incurred labor hours at standard rates to the Company’s estimate of the total labor hours at standard rates it expects to incur over the term of the contract. The Company believes this methodology achieves a reliable measure of the revenue from the consulting services it provides to its customers under fixed-price contracts given the nature of the consulting services the Company provides. The following table discloses the percent of the Company’s revenue generated from fixed price contracts: Engineering & other scientific ..................................................

During 2020, $8,815,000 of revenues were recognized that were included in the deferred revenue balance at January 3, 2020. During 2019, $5,754,000 of revenue were recognized that were included in the deferred revenue balance at December 28, 2018. During 2018, $6,067,000 of revenues were recognized that were included in the deferred revenue balance at December 29, 2017. Reimbursements, including those related to travel and other out-of-pocket expenses, and other similar third-party costs such as the cost of materials and certain subcontracts, are included in revenues, and an equivalent amount of reimbursable expenses are included in operating expenses. Any mark-up on reimbursable expenses is included in revenues before reimbursements. The Company reports revenues net of subcontractor fees for certain subcontracts where the Company has determined that it is acting as an agent because its performance obligation is to arrange for the provision of goods or services by another party. The total amount of subcontractor fees not included in revenues because the Company was acting as an agent were $9,408,000, $14,409,000 and $23,174,000 during 2020, 2019 and 2018, respectively. 51 Note 3: Cash, cash equivalents and short-term investments Cash, cash equivalents and short-term investments consisted of the following as of January 1, 2021: (In thousands) Classified as current assets: Amortized Cost Unrealized Gains Unrealized Losses Estimated Fair Value Cash .............................................................................................. $ 146,083 $ — $ — $ 146,083 Cash equivalents: Money market securities .........................................................

There have been no transfers between fair value measurement levels during 2020, 2019 and 2018. Any transfers between fair value measurement levels would be recorded on the actual date of the event or change in circumstances that caused the transfer. The fair value of these certain financial assets and liabilities was determined using the following inputs at January 1, 2021 (in thousands): Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets Money market securities (1)............................................... $ 51,442 $ 51,442 $ — $ Fixed income available for sale securities (2) ................... 45,001 — 45,001 Fixed income trading securities held in deferred compensation plan (3) ...................................... 26,274 26,274 — Equity trading securities held in deferred compensation plan (3)............................................................................ 62,473 62,473 — Total ................................................................................. $ 185,190 $ 140,189 $ 45,001 $ Liabilities Deferred compensation plan (4)......................................... 88,977 88,977 Total ................................................................................. $ 88,977 $ 88,977 $ — — $ — — — — — — — (1) (2) (3) (4) Included in cash and cash equivalents on the Company’s consolidated balance sheet.

Included in accounts payable and accrued liabilities and deferred compensation plan liabilities on the Company’s consolidated balance sheet. Fixed income available-for-sale securities as of January 1, 2021 and January 3, 2020 represent primarily obligations of the United States Treasury. Fixed income and equity trading securities represent mutual funds held in the Company’s deferred compensation plan. See Note 11 for additional information about the Company’s deferred compensation plan. At January 1, 2021 all short-term fixed income securities classified as short-term investments were due to mature within one year. At January 1, 2021 and January 3, 2020, the Company did not have any assets or liabilities valued using significant unobservable inputs. The following financial instruments are not measured at fair value on the Company's consolidated balance sheet at January 1, 2021 but require disclosure of their fair values: accounts receivable, other assets and accounts payable. The estimated fair value of such instruments at January 1, 2021 approximates their carrying value as reported on the consolidated balance sheet. There were no other-than-temporary impairments or credit losses related to available-for-sale securities during 2020, 2019 and 2018. 54 Note 5: Property, Equipment and Leasehold Improvements (In thousands) Property: Land............................................................................................................... $ Buildings .......................................................................................................

The Company is entitled to a deduction for federal and state tax purposes with respect to employees’ stock award activity. The net deduction in taxes otherwise payable arising from that deduction has been recorded as an income tax benefit. For 2020, 2019 and 2018, the net deduction in tax payable arising from employees’ stock award activity was $12,258,000, $8,067,000 and $4,154,000, respectively. 57 The Company and its subsidiaries file income tax returns in the United States federal jurisdiction, California and various other state and foreign jurisdictions. The Company is no longer subject to United States federal income tax examination for years prior to 2017. The Company is no longer subject to California franchise tax examinations for years prior to 2016. The California Franchise Tax Board is currently examining the Company’s 2017 and 2018 returns. With few exceptions, the Company is no longer subject to state and local or non-United States income tax examination by tax authorities for years prior to 2016. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Balance at December 28, 2018 .................................................................................................... $ Additions based on tax positions related to the current year.......................................................

To the extent these unrecognized tax benefits are ultimately recognized, they will impact the effective tax rate by $1,514,000 in a future period. There are no uncertain tax positions whose resolution in the next 12 months is expected to materially affect operating results. 58 Note 8: Stockholders’ Equity Preferred Stock The Company has authorized 2,000,000 shares of undesignated preferred stock with a par value of $0.001 per share. None of the preferred shares were issued and outstanding at January 1, 2021 and January 3, 2020.

Repurchase of Common Stock The Company repurchased 636,000 shares of its common stock for $40,049,000 during 2020. The Company repurchased 342,000 shares of its common stock for $21,957,000 during 2019. The Company repurchased 562,000 shares of its common stock for $27,915,000 during 2018. On May 29, 2020, the Board of Directors authorized $45,000,000 for the repurchase of the Company’s common stock. On January 31, 2019 the Board of Directors authorized $75,000,000 for the repurchase of the Company’s common stock. These repurchase programs have no expiration dates. As of January 1, 2021, the Company had remaining authorization under its stock repurchase plan of $75,455,000 to repurchase shares of common stock. Note 9: Stock-Based Compensation On May 29, 2008, the Company’s stockholders approved the 2008 Equity Incentive Plan and the 2008 Employee Stock Purchase Plan (“ESPP”). The 2008 Equity Incentive Plan and ESPP were previously adopted by the Company’s Board of Directors on April 8, 2008, subject to stockholder approval. 59 The 2008 Equity Incentive Plan allows for the award of stock options, stock awards (including stock units, stock grants and stock appreciation rights or other similar equity awards) and cash awards to officers, employees, consultants and non-employee members of the Board of Directors. The total number of shares reserved for issuance under the 2008 Equity Incentive Plan was 11,856,300 shares of common stock, subject to adjustment resulting from a stock split or the payment of a stock dividend or any other increase or decrease in the number of issued shares of the Company’s stock effected without receipt of consideration by the Company. As of January 1, 2021, 1,817,364 shares were available for grant under the 2008 Equity Incentive Plan. The ESPP allows for officers and employees to purchase common stock through payroll deductions of up to 15% of a participant’s eligible compensation. Shares of common stock are purchased under the ESPP at 95% of the fair market value of the Company’s common stock on each purchase date. Subject to adjustment resulting from a stock split or the payment of a stock dividend or any other increase or decrease in the number of issued shares of the Company’s stock effected without receipt of consideration by the Company, the total number of shares reserved for issuance under the ESPP was 1,200,000 shares of common stock. As of January 1, 2021, 362,171 shares were available for grant. Weighted average purchase prices for shares sold under the ESPP plan in 2020, 2019 and 2018 were $73.22, $60.32 and $45.26, respectively. Restricted Stock Units The Company grants restricted stock units to employees and outside directors. These restricted stock unit grants are designed to attract and retain employees, and to better align employee interests with those of the Company’s stockholders. For a select group of employees, up to 40% of their annual bonus is settled with fully vested restricted stock unit awards. Under these fully vested restricted stock unit awards, the holder of each award has the right to receive one share of the Company’s common stock for each fully vested restricted stock unit four years from the date of grant. Each individual who received a fully vested restricted stock unit award is granted a matching number of unvested restricted stock unit awards. These unvested restricted stock unit awards cliff vest four years from the date of grant, at which time the holder of each award will have the right to receive one share of the Company’s common stock for each restricted stock unit award, provided the holder of each award has met certain employment conditions. In the case of retirement at 59 ½ years or older, all unvested restricted stock unit awards will continue to vest provided the holder of each award does all consulting work through the Company and does not become an employee for a past or present client, beneficial party or competitor of the Company. All restricted stock units granted have dividend equivalent rights (“DER”), which entitle holders of restricted stock units to the same dividend value per share as holders of common stock. DER are subject to the same vesting and other terms and conditions as the corresponding unvested restricted stock units. DER are accumulated and paid when the underlying shares vest and are forfeited if the underlying shares are forfeited. The value of these restricted stock unit awards is determined based on the market price of the Company’s common stock on the date of grant. The value of fully vested restricted stock unit awards issued is recorded as a reduction to accrued bonuses. The portion of bonus expense that the Company expects to settle with fully vested restricted stock unit awards is recorded as stock-based compensation during the period the bonus is earned. For 2020, 2019 and 2018, the Company recorded stock-based compensation expense associated with accrued bonus awards of $8,112,000, $8,756,000 and $8,443,000 respectively. The Company recorded stock-based compensation expense associated with the unvested restricted stock unit awards of $8,472,000, $8,127,000 and $7,653,000 during 2020, 2019 and 2018, respectively. The total fair value of restricted stock unit awards vested during 2020, 2019, and 2018 was $31.3 million, $25.6 million and $23.2 million, respectively. The weighted-average grant date fair values of restricted stock unit awards granted during 2020, 2019 and 2018 were $68.21, $57.08 and $40.61, respectively. 60 The number of unvested restricted stock unit awards outstanding as of January 1, 2021 is as follows (1): Number of awards outstanding Weighted- average grant date fair value Weighted- average remaining contractual term (years) Aggregate intrinsic value (in thousands) (2) Balance as of January 3, 2020.........................

(2) The intrinsic value is calculated as the market value as of the end of the fiscal period. As reported by the NASDAQ Global Select Market, the market value as of January 1, 2021 was $90.03. Stock Options The Company currently grants stock options under the 2008 Equity Incentive Plan. Options are granted for terms of ten years and generally vest ratably over a four-year period from the grant date. The Company grants options at exercise prices equal to the fair value of the Company’s common stock on the date of grant. All stock options have dividend equivalent rights, which entitle holders of stock options to the same dividend value per share as holders of common stock. DER are subject to the same vesting terms as the corresponding stock options. DER are accumulated and paid in cash when the underlying stock options vest and are forfeited if the underlying stock options do not vest. During 2020, 2019 and 2018, the Company recorded stock-based compensation expense of $694,000, $583,000 and $897,000, respectively, associated with stock options. Option activity is as follows (1): Number of shares outstanding Weighted- average exercise price Weighted- average remaining contractual term (years) Aggregate intrinsic value (in thousands) Balance as of January 3, 2020......................... Options granted ......................................... Options forfeited and expired.................... Options exercised ...................................... 662,149 $ 40,000 — (283,755) 26.23 79.43 — 17.41 Balance at January 1, 2021 ............................. 418,394 $ 37.29 6.56 $ 22,066 Exercisable at January 1, 2021........................ 263,894 $ 29.24 5.89 $ 16,042 (1) Does not include restricted stock or employee stock purchase plans. The total intrinsic value of options exercised during 2020, 2019 and 2018 was $18,211,000, $9,651,000 and $0, respectively. The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the fiscal year ended January 1, 2021, and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on January 1, 2021. This amount changes based on the fair-value of the Company’s stock. 61 The Company uses the Black-Scholes option-pricing model to determine the fair value of options granted. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. The Company used historical exercise and post-vesting forfeiture and expiration data to estimate the expected term of options granted. The historical volatility of the Company’s common stock over a period of time equal to the expected term of the options granted was used to estimate expected volatility. The risk-free interest rate used in the option- pricing model was based on United States Treasury zero coupon issues with remaining terms similar to the expected term on the options. The dividend yield assumption considers the expectation of continued declaration of dividends, offset by option holders’ dividend equivalent rights. All stock-based payment awards are recognized on a straight-line basis over the requisite service periods of the awards. The assumptions used to value option grants for 2020, 2019 and 2018 are as follows: Stock Option Plan Fiscal Years 2019 2018 2020 Expected term (in years)................................................................... Risk-free interest rate........................................................................ Volatility...........................................................................................

The employee does not need to make a contribution to the plan to be eligible for the Company’s 7% contribution. To be eligible under the plan, an employee must be at least 21 years of age and be either a full-time or part-time salaried employee. The 7% Company contribution will vest 20% per year for the first 5 years of employment and then immediately thereafter. The Company’s expenses related to this plan were $9,752,000, $9,073,000, and $8,419,000 in 2020, 2019, and 2018, respectively. Note 11: Deferred Compensation Plans The Company maintains nonqualified deferred compensation plans for the benefit of a select group of highly compensated employees. Under these plans, participants may elect to defer up to 100% of their compensation. Company assets that are earmarked to pay benefits under the plans are held in a rabbi trust and are subject to the claims of the Company’s creditors. As of January 1, 2021, and January 3, 2020, the invested amounts under the plans totaled $88,747,000 and $75,934,000, respectively. These assets are classified as trading securities and are recorded at fair market value with changes recorded as adjustments to other income. As of January 1, 2021, and January 3, 2020, vested amounts due under the plans totaled $88,977,000 and $76,357,000, respectively. Changes in the liability are recorded as adjustments to compensation expense. During 2020, 2019 and 2018, the Company recognized compensation expense/(gain) of $8,028,000, $12,834,000 and $(3,900,000), respectively, as a result of changes in the market value of the trust assets with the same amount being recorded as other income. Note 12: Leases The Company determines if an arrangement is a lease at the inception of the arrangement. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and long-term operating lease liabilities in the Company’s consolidated balance sheet. The Company does not have any finance leases as of January 1, 2021. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, based on the information available at commencement date, in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The Company’s lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The amortization of operating lease ROU assets and the change in operating lease liabilities is disclosed as a single line item in the consolidated statement of cash flows. The Company leases office, laboratory, and storage space in 13 states and the District of Columbia, as well as in China, Hong Kong, Singapore, Switzerland and the United Kingdom. Leases for these office, laboratory, and storage facilities have terms generally ranging between one and ten years. Some of these leases include options to extend or terminate the lease, none of which are currently included in the lease term as the Company has determined that exercise of these options is not reasonably certain. The Company has a Test and Engineering Center on 147 acres of land in Phoenix, Arizona. The Company leases this land from the state of Arizona under a 30-year lease agreement that expires in January of 2028 and has options to renew for two fifteen-year periods. As of January 1, 2021, the Company has determined that exercise of the renewal options is not reasonably certain and thus the extension is not included in the lease term. The Company’s equipment leases are included in the ROU asset and liability balances but are not material. 63 The components of lease expense included in other operating expenses on the consolidated statement of income were as follows: (In thousands) Operating lease cost...................................................................................................... $ Variable lease cost ........................................................................................................
