Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation--The consolidated financial statements include the accounts of Davey Tree and our wholly-owned subsidiaries and were prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") as codified in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"). Intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates in Financial Statement Preparation--The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts. Estimates are used for, but not limited to, accounts receivable valuation, depreciable lives of fixed assets, long-lived asset and goodwill valuation, self-insurance accruals, stock valuation and revenue recognition. Actual results could differ from those estimates.

Our business continues to be impacted, in varying degrees, by a number of macro-economic factors, including higher fuel costs, rising interest rates and a highly competitive labor market, which have created an inflationary environment and cost pressures.

The Company’s fiscal quarters each contain thirteen operating weeks, with the exception of the fourth quarter of a 53-week fiscal year, which contains fourteen operating weeks.

Mitigation Banking Credit Inventory--Our mitigation banking business creates and sells wetland, stream and other environmental credits and provides services to those engaged in permittee-responsible mitigation and environmental restoration. We record mitigation bank

credit inventory at the lower of cost or net realizable value. Inventory costs are based on estimated total costs for each mitigation bank, which could change as we perform mitigation banking activities.

Property and Equipment--Property and equipment are stated at cost. Repair and maintenance costs are expensed as incurred. Depreciation is computed for financial reporting purposes by the straight-line method for land improvements, building and leasehold improvements and by the declining-balance method for equipment, based on the estimated useful lives of the assets, as follows:


Land improvements			5 to 20 years
Buildings			5 to 30 years
Equipment			3 to 20 years
Leasehold improvements			Shorter of lease term or estimated useful life; ranging from 5 to 20 years

Intangible Assets--Intangible assets with finite lives, primarily customer lists, noncompete agreements and tradenames, are amortized by the straight-line method based on their estimated useful lives, ranging from one year to seven years.

Long-Lived Assets--We assess potential impairment to our long-lived assets, other than goodwill, when there is evidence that events or changes in circumstances have made recovery of the asset’s carrying value unlikely and the carrying amount of the asset exceeds the estimated future undiscounted cash flow. In the event the assessment indicates that the carrying amounts may not be recoverable, an impairment loss would be recognized to reduce the asset’s carrying amount to its estimated fair value based on the present value of the estimated future cash flows.

Goodwill--Goodwill is recorded when the cost of acquired businesses exceeds the fair value of the identified net assets acquired. Goodwill is not amortized, but tested for impairment annually or when events or circumstances indicate that impairment may have occurred. Annually, we perform the impairment tests for goodwill during the fourth quarter. Our annual impairment assessment date has been designated as the first day of our fourth fiscal quarter. Impairment of goodwill is tested at the reporting-unit level, which for us are also our business segments. Impairment of goodwill is tested by comparing the reporting unit’s carrying value, including goodwill, to the fair value of the reporting unit. The fair values of the reporting units are estimated using discounted projected cash flows. If the carrying value of the reporting unit exceeds its fair value, goodwill is considered impaired and an impairment loss should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the carrying value of the goodwill allocated to that reporting unit. We conducted our annual impairment tests and determined that no impairment loss was required to be recognized in 2023 or for any prior periods. There were no events or circumstances from the date of our assessment through December 31, 2023 that would impact this conclusion.

Self-Insurance Accruals--We are generally self-insured for losses and liabilities related primarily to workers’ compensation, vehicle liability and general liability claims. We use commercial insurance as a risk-reduction strategy to minimize catastrophic losses. Self-insurance accruals consist of the projected settlement value of reported and unreported claims. Ultimate losses are accrued based upon estimates of the aggregate liability for claims incurred using certain actuarial assumptions followed in the insurance industry and based on Company-specific experience.

Our self-insurance accruals include claims for which the ultimate losses will develop over a period of years. Estimating ultimate losses of reported and unreported claims is subject to a high degree of variability as it involves complex estimates that are generally derived using a

variety of actuarial estimation techniques and numerous assumptions and expectations about future events, many of which are highly uncertain. Accordingly, our estimates of ultimate losses can change as claims mature. Our accruals also are affected by changes in the number of new claims incurred and claim severity. The methods for estimating the ultimate losses and the total cost of claims were determined by third-party consulting actuaries; the resulting accruals are reviewed by management, and any adjustments arising from changes in estimates are reflected in income.

Our self-insurance accruals are based on estimates and, while we believe that the amounts accrued are adequate and not excessive, the ultimate claims may be in excess of or less than the amounts provided. Changes in claims incurred, claim severity, or other estimates and judgments used by management could have a material impact on the amount and timing of expense for any period.

Stock-Based Compensation--Stock-based compensation cost for all share-based payment plans is measured at fair value on the date of grant and recognized over the employee service period on the straight-line recognition method for awards expected to vest. The fair value of all stock-based payment plans—stock option plans, stock-settled stock appreciation rights, and performance-based restricted stock units as well as our Employee Stock Purchase Plan—is determined by the number of awards granted and the price of our common stock. The fair value of each award is estimated on the date of grant using a binomial option-pricing model. The binomial model considers a range of assumptions related to volatility, risk-free interest rate and employee exercise behavior. Expected volatilities utilized in the binomial model are based on historical volatility of our share prices and other factors. Similarly, the dividend yield is based on historical experience and expected future changes. The binomial model also incorporates exercise assumptions based on an analysis of historical data. The expected life of the stock-based awards is derived from the output of the binomial model and represents the period of time that awards granted are expected to be outstanding.

Income Taxes--We compute taxes on income in accordance with the tax rules and regulations where the income is earned. The income tax rates imposed by these taxing authorities vary. Taxable income may differ from pretax income for financial reporting purposes. We compute and recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of our assets and liabilities. Changes in tax rates and laws are reflected in income in the period when such changes are enacted. We account for uncertain tax positions by recognizing the financial statement effects of a tax position only when, based upon the technical merits, it is more-likely-than-not that the position will be sustained upon examination.

Earnings Per Share--Basic earnings per share is determined by dividing the income available to common shareholders by the weighted-average number of common shares outstanding. Diluted earnings per share is computed similarly to basic earnings per share except that the weighted-average number of shares is increased to include the effect of stock awards that were granted and outstanding during the period.

Revenue Recognition--We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. See Note S for a detailed description of our revenue recognition policy.

Concentration of Credit Risk--Credit risk represents the accounting loss that would be recognized if the counterparties failed to perform as contracted. The principal financial instruments subject to credit risk are as follows:

Cash--To limit our exposure, we transact our business and maintain banking relationships with high credit-quality financial institutions.

Accounts Receivable--Our residential and commercial customers are located geographically throughout the United States and Canada and, as to commercial customers, within differing industries; thus, minimizing credit risk. The credit exposure of utility services customers is directly affected by conditions within the utility industries as well as the financial condition of individual customers. One utility customer approximated 10% of revenues during 2023, 11% in 2022 and 13% in 2021. To reduce credit risk, we evaluate the credit of customers, but generally do not require advance payments or collateral. Exposure to losses on receivables is principally dependent on each customer’s financial condition.

Foreign Currency Translation and Transactions--Assets and liabilities of our Canadian operations are translated into U.S. dollars using year-end exchange rates, and revenues and expenses are translated using exchange rates as determined throughout the year. Gains or losses resulting from translation are included in the consolidated balance sheet, classified in shareholders’ equity as a separate component of accumulated other comprehensive income (loss). Gains or losses resulting from Canadian-dollar transactions with the Canadian operations are converted to U.S. dollars at the rates of exchange prevailing at the dates of the transactions. The effect of the transactions gain or loss is classified in the statement of operations as a component of other non-operating income (expense), net.

Comprehensive Income (Loss)--Comprehensive income (loss) includes net income and other comprehensive income or loss. Other comprehensive income (loss) refers to revenues, expenses, gains and losses that under U.S. GAAP are included in comprehensive income but are excluded from net income as these amounts are recorded directly as an adjustment to shareholders’ equity, net of tax.
