Our business, results of operations, financial position or cash flow could in the future be materially adversely impacted by the COVID-19 pandemic.

The Davey Tree Expert Company, which was founded in 1880 and incorporated in Ohio in 1909, and its subsidiaries ("we" or "us") provide a wide range of arboricultural, horticultural, environmental and consulting services to our customers throughout the United States and Canada. We have two reportable operating segments organized by type or class of customer: Residential and Commercial, and Utility.

Our Residential and Commercial segment provides services to our residential and commercial customers including: the treatment, preservation, maintenance, removal and planting of trees, shrubs and other plant life; the practice of landscaping, grounds maintenance, tree surgery, tree feeding and tree spraying; the application of fertilizer, herbicides and insecticides; and natural resource management and consulting, forestry research and development, and environmental planning.

Our Utility segment is principally engaged in providing services to our utility customers--investor-owned, municipal utilities, and rural electric cooperatives--including: the practice of line-clearing and vegetation management around power lines and rights-of-way and chemical brush control; andcontrol, natural resource management and consulting, forestry research and development and environmental planning.

We also maintain research, technical support and laboratory diagnostic facilities.

Our Residential and Commercial segment is one of the largest national tree care organizations in the United States, and competes with other national and local firms with respect to its services. On a national level, our competition is primarily landscape construction and maintenance companies as well as residential and commercial lawn care companies. At a local and regional level, our competition comes mainly from small, local companies which are engaged primarily in tree care and lawn services. Our Utility segment is the second largest organization in the industry in the United States, and competes principally with one major national competitor, The Asplundh Tree Expert, Co.,LLC, as well as several smaller regional firms.

Principal methods of competition in both operating segments are customer service, marketing, image, performance and reputation. Our program to meet our competition stresses the necessity for our employees to have and project to customers a thorough knowledge of all horticultural services provided, and utilization of modern, well-maintained equipment. Pricing is not always a critical factor in a customer's decision with respect to our Residential and Commercial segment; however, pricing is generally the principal method of competition for our Utility segment, although in most instances consideration is given to reputation and past production performance.

We provide a wide range of horticultural services to private companies, public utilities, local, state and federal agencies, and a variety of industrial, commercial and residential customers. During 2019,2021, we had revenues of approximately $137$176 million, or approximately 12%13% of total revenues, from Pacific Gas & Electric Company ("PG&E"), our largest customer. On January 29, 2019, PG&E filed for Chapter 11 bankruptcy. As a utility company, PG&E serves residential and industrial customers in California and has an ongoing obligation to continue to serve its customers. Therefore, we do not anticipate PG&E's bankruptcy to have a material impact on our future cash flows and results of operations.

We solicit business from residential customers principally through referrals, direct mail programs and to a lesser extent through the placement of advertisements in national magazines and trade journals, local newspapers and "yellow pages" telephone directories. We also employ online marketing and lead generation strategies, including email marketing campaigns, search engine optimization, search engine marketing, and social media communication. Business from utility and commercial customers is obtained principally through negotiated contracts and competitive bidding. We carry out all of our sales and services through our employees. We generally do not use agents, and do not franchise our name or business.

Our business is seasonal, primarily due to fluctuations in horticultural services provided to Residential and Commercial customers. We can also be affected to a lesser extent by budget constraints of our Utility customers. Because of this seasonality, we have historically incurred losses in the first quarter, while sales and earnings are generally highest in the second and third quarters of the calendar year. Consequently, this has created heavy demands for additional working capital at various times throughout the year. We borrow primarily against bank commitments in the form of a revolving credit facility and issue notes to provide the necessary funds for our operations. You can find more information about our bank commitments in “Liquidity"Liquidity and Capital Resources”Resources" of this report under “Management’s"Management’s Discussion and Analysis of Financial Condition and Results of Operations.”"

Due to rapid changes in equipment technology and intensity of use, we must constantly update our equipment and processes to ensure that we provide competitive services to our customers and continue our compliance with the Occupational Safety and Health Act.

We own several trademarks including "Davey," "Davey and Design," "Arbor Green Pro," "Arbor Green," and "Davey Resource Group." Through substantial advertising and use, we believe that these trademarks have become of value in the identification and acceptance of our products and services.

Our values — safety, integrity, expertise, leadership, stewardship and perseverance — are built on the foundation that our people are the key to our success and sustainability as a company. We aim to engage and inspire our employees every day, providing them with education and development opportunities to help them grow personally and professionally. As of December 31, 2021, we employed approximately 9,70010,200 people, of which approximately 92% were in the United States and 8% were in our Canadian locations. Of our active employees, at December 31, 2019. However, employment levels fluctuate due to seasonal factors affecting our business.

99% are full time, 1% are part time and 14% are covered by a collective bargaining agreement. We consider our employee relations to be good.

We sell our services to customers in the United States and Canada.

We do not consider the risks associated with our business with foreign customers, other than currency exchange risks, to be materially different from those of our domestic customers.

The following documents are also made available on our website and a copy will be mailed, without charge, upon request to our Corporate Secretary:

The factors described below represent the principalmaterial risks we face. ExceptDisclosure of risks should not be interpreted to imply that the risks have not already materialized, and, except as otherwise indicated, these factors may or may not occur and we are not in a position to express a view on the likelihood of any such factor occurring. Other factors may exist that we do not consider to be significantmaterial based on information that is currently available or that we are not currently able to anticipate.

Our industry operates in an environment that requires heavy manual labor. We may experience slower growth in the labor force for this type of work than in the past. As a result, weWe also may experiencebe constrained in hiring and retaining sufficient qualified employees to support our growth strategy due to general labor shortages in our industry, including potential employee attrition in connection with any applicable

government or the needcustomer COVID-19 vaccine or testing mandates. In addition, a lack of qualified labor or increased turnover rates within our employee base could lead to pay moreincreased costs, such as increased overtime to meet demand and increased wage rates to attract and retain qualified employees. Additionally, changes to the laws and regulations that govern the classification or wages of workers may require us to make changes to our operations and may negatively impact our business, increase our costs and expose us to various liabilities.

We are generally self-insured for losses and liabilities related to workers' compensation, vehicle liability and general liability claims (including any wildfire-related claims, up to certain retained coverage limits). A liability for unpaid claims and associated expenses, including incurred but not reported losses, is actuarially determined and reflected in our consolidated balance sheet as an accrued liability. The determination of such claims and expenses, and the extent of the need for accrued liabilities, are continually reviewed and updated. If we were to experience insurance claims or costs above our estimates and were unable to offset such increases with earnings, our business could be adversely affected. Also, where we self-insure, a deterioration in claims management, whether by our management or by a third-party claims administrator, could lead to delays in settling claims, thereby increasing claim costs, particularly as it relates to workers’ compensation. In addition, catastrophic

Furthermore, many customers, particularly utilities, prefer to do business with contractors with significant financial resources, who can provide substantial insurance coverage. Should we be unable to renew our excess liability insurance and other commercial insurance policies at competitive rates, this loss would have an adverse effect on our financial condition and results of operations.

Any of our existing excess insurance coverage may not be renewed upon the expiration of the coverage period or future coverage may not be available at competitive rates for the required limits. In addition, our third-party insurers could fail, suddenly cancel our coverage or otherwise be unable to provide us with adequate insurance coverage. If any of these events occur, they may have a material adverse effect on our financial condition and results of operations as well as disrupt our operations. For example, we have operations in California, which has an environment prone to wildfires. Should our third-party insurers determine to exclude coverage for wildfires in the future, we could

be exposed to significant liabilities, havingwhich would have a material adverse effect on our financial condition and results of operations and potentially disruptingdisrupt our California operations.

Our business, other than tree services to utility customers, is highly seasonal and weather dependent, primarily due to fluctuations in horticultural services provided to Residential and Commercial customers. We have historically incurred losses inBased on the first quarter, whilegeographic areas we service, revenue and operating income are generally highest in the second and third quarters of the calendar year. Inclement weather, such as uncharacteristically low or high (drought) temperatures or storms, floods, and other events, the frequency, pattern or intensity of which may be increased by climate change, in the second and third quarters could dampen the demand for our horticultural services, resulting in reduced revenues that would have an adverse effect on our results of operations.

Our ability to collect our accounts receivable and future sales depends, in part, on the financial strength of our customers. We grant credit, generally without collateral, to our customers. Consequently, we are subject to credit risk related to changes in business and economic factors throughout the United States and Canada. In the event customers experience financial difficulty, and particularly if bankruptcy results, our profitability may be adversely impacted by our failure to collect our accounts receivable in excess of our estimated allowance for uncollectible accounts. Additionally, our future revenues could be reduced by the loss of a customer due to bankruptcy. Our failure to collect accounts receivable and/or the loss of one or more major customers could have an adverse effect on our net income and financial condition.

From time-to-time, customers, vendors, employees, governmental regulatory authorities and others may makehave made claims and taketaken legal action against us.us, and may do so in the future. Allegations, claims or proceedings may, for example, relate to personal injury, property damage, general liability claims, vehicle accidents involving our vehicles and our employees, regulatory issues, contract disputes or employment matters and may include class actions. Defending against these and other such claims and proceedings is costly and time consuming and may divert management’s attention and personnel resources from our normal business operations, and the outcome of many of these claims and proceedings cannot be predicted. Whether these claims and legal actions are founded or unfounded, if such claims and legal actions are not resolved in our favor, they may result in significant financial liability. Any such financial liability could have a material adverse effect on our financial condition and results of operations. While we carry a broad range of insurance for the protection of our assets and operations, such insurance may not fully cover all material expenses related to potential allegations, claims and proceedings, or any adverse judgments, fines or settlements that may result. We reserve currently for anticipated losses and related expenses in excess of anticipated insurance coverage that may exist.

The cost of fuel is a major operating expense of our business. Significant increases in fuel prices for extended periods of time will cause our operating expenses to fluctuate. An increase in cost with partial or no corresponding compensation from customers would lead to lower margins that would have an adverse effect on our results of operations.

Many scientists, environmentalists, international organizations, political activists, regulatorsRecently, there has been growing concern from advocacy groups, government agencies and other commentators believe that globalthe general public over the effects of climate change has added,on the environment. Transition risks, such as government restrictions, standards or regulations intended to reduce greenhouse gas emissions and will continue to add, topotential climate change impacts, are emerging and may increase in the unpredictability, frequency and severity of natural disasters in certain parts of the world. In response,future. For example, a number of legal and regulatory measures and social initiatives have been introduced in an effort to reduce greenhouse gas and other carbon emissionsemissions. Any such initiatives, restrictions and requirements could restrict our operating activities, require us to make changes in our operating activities that would increase our operating costs, reduce our efficiency or limit our output, require us to make capital improvements to our facilities, increase our energy, raw material and transportation costs or limit their availability, or otherwise adversely affect our results of operations, liquidity or capital resources, and these partieseffects could be material to us. We believe we are in compliance in all material respects with existing climate-related government restrictions, standards and regulations applicable to our business, and such compliance has not had a material impact on our business. However, given the rapidly changing nature of environmental laws and matters that may arise that are not currently known, we cannot predict our future exposure concerning such matters, and our future costs to achieve compliance or remedy potential violations could be contributors to global climate change. These proposals, if enacted, could result in a variety of regulatory programs, including potential new regulations, additional charges and taxes to fund energy efficiency activities, or other regulatory actions. Any of these actions could result in increased costs associated with our operations and impact the prices we charge our customers.significant.

We cannot predict the impact, if any, that changing climate conditions will have on us or our customers. However, it is possible thatcustomers, as the legal, regulatory and social responses to real or perceivedprospective impact of climate change on our operations and those of our customers remains uncertain. Our industry is subject to seasonal and weather factors, which can vary from period to period. Climate change may increase the frequency, patterns or intensity of extreme weather such as storms, floods, heat waves, droughts and other events, as well as result in changing sea levels and temperature levels, and these changes could have a negative effectbe severe and could vary by geographic location. At the present time, we cannot predict the prospective impact of climate change on our results of operations, liquidity or our financial condition.capital resources, or whether any such effects could be material to us.

We have experienced and expect to continue to experience quarterly variations in revenues and operating income as a result of many factors, including:

Accordingly, our operating results in any particular quarter may not be indicative of the results that you can expect for any other quarter or for the entire year.

Our Residential and Commercial segment and our Utility segment frequently operate in a competitive bid contract environment. As a result, we may misjudge a bid and be contractually bound to an unprofitable contract, which could adversely affect our results of operations.

We rely on the accuracy, capacity and security of our information technology systems. Despite the security measures that we have implemented, including those measures related to cybersecurity, our systems, or the systems of third parties upon whom we rely, could be breached or damaged by computer viruses, natural or man-made incidents or disasters, including third-party action, insider attacks, employee or service provider error or malfeasance, phishing or denial-of-service attacks, ransomware or other malware, or social engineering, other unauthorized physical or electronic access.access, or otherwise. A cyberattack or breach involving our information technology systems or those of our suppliers or other partners could result in business disruption, including disruptions in critical systems, corruption or loss of data, loss or theft of funds, theft of our intellectual property, trade secrets, customer information or other data and unauthorized access to, or release of, personnel information. In addition, we face increased information technology security and fraud risks due to our increased reliance on working remotely due to the COVID-19 pandemic, which may create additional information security vulnerabilities and/or magnify the impact of any disruption in information technology systems. To the extent that our business is interrupted or data is lost, destroyed or inappropriately used or disclosed, such disruptions could adversely affect our competitive position, reputation, relationships with our customers, financial condition, operating results and cash flows and could expose us to data loss, allow others to unfairly compete with us, and subject us to litigation, government enforcement actions, regulatory penalties and costly response measures. In addition, we may be required to incur significant costs to protect against the damage caused by these disruptions or security breaches in the future, and we may not have adequate insurance coverage to compensate us for any losses relating to such events.

Because the techniques used to obtain unauthorized access to, or disable, degrade or sabotage, information technology systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques, implement adequate preventative measures or remediate any intrusion on a timely or effective basis. Moreover, the development and maintenance of these preventative and detective measures is costly and requires ongoing monitoring and updating as technologies change and efforts to overcome security measures become more sophisticated. We, therefore, remain potentially vulnerable to additional known or yet unknown threats, as in some instances, we, or our suppliers and other partners, may be unaware of an incident or its magnitude and effects. We also

face the risk that we may expose our customers or partners to cybersecurity attacks. Any of these factors could have a material adverse effect on us.

In addition, we may incur costs in order to comply with cybersecurity or data privacy regulations in the regions in which we operate.operate, or with requirements imposed by customers. Such regulations and requirements continue to evolve and are increasingly demanding, which may impose additional requirements on usincrease our costs of compliance and increase our regulatory and litigation risk.

We are dependent, in part, upon our reputation of quality, integrity and performance. If our reputation were damaged in some way, it may impact our ability to grow or maintain our business.

Our facilities and operations are subject to governmental regulations designed to protect the environment, particularly with respect to our services regarding insect and tree, shrub and lawn disease management, because these services involve to a considerable degree the blending and application of spray materials, which require formal licensing in most areas. Continual changes in environmental laws, regulations and licensing requirements, including those related to climate change, environmental conditions, environmental awareness, technology and social attitudes, make it necessary for us to maintain a high degree of awareness of the impact such changes have on our compliance programs and the market for our services. We are subject to existing federal, state and local laws, regulations and licensing requirements regulating the use of materials in our spraying operations as well as certain other aspects of our business. If we fail to comply with such laws, regulations or licensing requirements, we may become subject to significant liabilities, fines and/or penalties, which could adversely affect our financial condition and results of operations.

We utilize surety bonds and letters of credit on a project-by-project basis and for our self-insurance program. If surety providers were to limit or eliminate our access to bonding, we would need to post other forms of collateral for project performance, such as letters of credit or cash. We may be unable to secure sufficient letters of credit on acceptable terms, or at all. Accordingly, if we were to experience an interruption or reduction in the availability of bonding capacity, our liquidity may be adversely affected.

Various economic factors, such as the ongoing effects of the COVID-19 pandemic, may adversely impact the demand for our services and potentially result in depressed prices for our services and the delay or cancellation of projects. That may make it difficult to estimate our customers' requirements for our services and, therefore, add uncertainty to customer demand. Various economic factors, such as any recession that has occurred, or may occur in the future, inflation, and customers' confidence in future economic conditions may cause a reduction in our customers' spending for our services and may also impact the ability of our customers to pay amounts owed, which could reduce our

We may need new or additional financing in the future to conduct our operations, expand our business or refinance existing indebtedness. Future changes in the general economic conditions and/or financial markets in the United States or globally could affect adversely our ability to raise capital on favorable terms or at all. From time-to-time we have relied, and may also rely in the future, on access to financial markets as a source of liquidity for working capital requirements, acquisitions and general corporate purposes. Our access to funds under our revolving credit facility is dependent on the ability of the financial institutions that are parties to the facility to meet their funding commitments. Those financial institutions may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time. Economic disruptions, such as the ongoing effects of the COVID-19 pandemic, and any resulting limitations on future funding, including any restrictions on access to funds under our revolving credit facility, could have a material adverse effect on us.

We are exposed to foreign currency exchange rate risk resulting from our operations in Canada, where we provide a comprehensive range of horticultural services. Our financial results could be affected by factors such as changes in the foreign currency exchange rate or differing economic conditions in the Canadian markets as compared with the markets for our services in the United States. Our earnings are affected by translation exposures from currency fluctuations in the value of the U.S. dollar as compared to the Canadian dollar.

Revenues from customers in Canada are subject to foreign currency exchange. Thus, certain revenues and expenses have been, and are expected to be, subject to the effect of foreign currency fluctuations, and these fluctuations may have a material adverse impact on our operating results and asset values and could reduce shareholders’ equity. In addition, if we expand our Canadian operations, exposures to gains and losses on foreign currency transactions may increase.

Our ability to offer affordable health care coverage to our employees is a significant expense to the business. Changes in our employees' behavior, cost of health care programs offered by third party providers or any future legislation or regulations that may be implemented at the federal or state level could impact our ability to provide health care coverage. Significant increases in the cost of health care coverage over time could have a material negative impact on our financial position, results of operations and cash flows and may also limit our ability to attract and retain qualified employees.

We utilize the U.S. government’s E-Verify program to assist in verifying the employment eligibility of potential new employees and require all new potential employees provide us with government-specified documentation evidencing their employment eligibility. However, the use of E-Verify does not guarantee that we will successfully identify all applicants who are ineligible for employment. While we believe we are in compliance with applicable laws and regulations of U.S. Immigration and Customs Enforcement, it is possible some of our employees may, without our knowledge, be unauthorized workers. The employment of unauthorized workers may subject the Company to fines, penalties and other costs related to compliance with laws and regulations as well as adverse publicity that negatively impacts our reputation and brand

regulations or enforcement programs. Changes in immigration or work authorization laws may increase our obligations for compliance and oversight, which could subject us to additional costs and potential liability and make our hiring process more cumbersome, or reduce the availability of potential employees.

There are no unresolved comments from the Staff of the SEC.

Our corporate headquarters campus is located in Kent, Ohio, which, along with several other properties in the surrounding area, includes The Davey Institute's research, technical support and laboratory diagnostic facilities.
