The following is a summary of the significant accounting policies and principles used in the preparation of the condensed consolidated financial statements:

Section 102(b)(1) of the Jumpstart Our Business Startups Act (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company that is either not an emerging growth company or, an emerging growth company that has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used.

Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contract with Customers (“ASC Topic 606”) provides a single comprehensive revenue recognition framework and supersedes almost all revenue recognition guidance including industry-specific revenue guidance. To determine the proper revenue recognition method under ASC Topic 606, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and if so, whether to account for the combined or single contract as more than one performance obligation. For most contracts, it is concluded that there is a single performance obligation because the promise to transfer individual goods or services is not separately identifiable from the commitment to the deliverable of the contract and, therefore, is not distinct.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) 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 reporting period. Actual results could vary from the estimates and assumptions that were used.

The Company’s financial instruments that are exposed to concentrations of credit risk consist of cash and accounts receivable.

Cash balances at various times during the year may exceed the amount insured by the Federal Deposit Insurance Corporation. The Company’s cash deposits are held in institutions whose credit ratings are monitored by management, and the Company has not incurred any losses related to such deposits.

The Company is subject to a concentration of credit risk with respect to outstanding accounts receivable. However the Company believes no such concentration existed during the three months ended March 31, 2021 or the year ended December 31, 2020. The Company’s customers are located throughout the United States. Although the Company generally grants credit without collateral, management believes that its contract acceptance, billing, and collection policies are adequate to minimize material credit risk. Also, for non-governmental customers, the Company can often place mechanics liens against the real property associated with the contract in the event of non-payment.

Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”) provides the framework for measuring and reporting financial assets and liabilities at fair value. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The codification establishes a three-level disclosure hierarchy to indicate the level of judgment used to estimate fair value measurements:

Level 1:Quoted prices in active markets for identical assets or liabilities as of the reporting date;

Level 2:Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices (such as interest rate and yield curves);

Level 3:Uses inputs that are unobservable, supported by little or no market activity and reflect significant management judgment.

•

The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the relatively short duration of these instruments;

•

The carrying amounts of debt obligations approximate their fair values as the terms are comparable to terms currently offered by local financial institutions for arrangements with similar terms to industry peers with comparable credit characteristics. Accordingly, the debt obligations involve Level 2 fair value inputs; and

•

The liability related to shares subject to repurchase is recognized at fair value using Level 3 inputs that were primarily determined based on the contractual settlement price as defined by the terms of the Company’s Shareholders’ Buy-Sell Agreement. For further discussion, see Note 16, Stock Bonus Plan.

The Company recognizes deferred income tax assets or liabilities for expected future tax consequences of events recognized in the consolidated financial statements or tax returns. Under this method, deferred income tax assets or liabilities are determined based upon the difference between the financial statement and income tax bases of assets and liabilities using enacted tax rates expected to apply when the differences settle or become realized. Valuation allowances are provided when it is more likely than not that a deferred tax asset is not realizable or recoverable in the future.

The Company recognizes the effect of a change in tax rates on deferred tax assets and liabilities in income in the period that includes the enactment date. The Company’s effective tax rate for the three months ended March 31, 2021 and 2020 was 28.0% and 25.0%. Exclusive of discrete items, the effective tax rate for the three months ended March 31, 2021 was 9.36%

The Company assesses uncertain tax positions to determine whether the position will more likely than not be sustained upon examination by the Internal Revenue Service (IRS) or other taxing authorities. If the Company cannot reach a more-likely-than-not determination, no benefit is recorded. If the Company determines that the tax position is more likely than not to be sustained, the Company records the largest amount of benefit that is more likely than not to be realized when the tax position is settled. The Company recognizes interest and penalties, if any, related to uncertain tax positions in income tax expense.

The Company files income tax returns in the U.S. federal jurisdiction and certain states in which it operates. Based on the timing of the filing of certain tax returns, the Company’s federal income tax returns for tax years 2017 and after remain subject to examination by the U.S. Internal Revenue Service. The statute of limitations on the Company’s state income tax returns generally conforms to the federal three-year statute of limitations.

The Company operates in one segment based upon the financial information used by its chief operating decision maker in evaluating the financial performance of its business and allocating resources. The single segment represents the Company’s core business of providing engineering and related professional services to its customers.

Leases. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (Topic 842) (“ASU 2016-02”) to increase transparency and comparability of accounting for lease transactions by requiring lessees to recognize the right-of-use assets and lease liabilities on the balance sheet and to disclose qualitative and quantitative information about lease transactions and enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The effective date of

ASU 2016-02 for the Company is January 1, 2022, with early adoption permitted. The Company is currently evaluating the impact this ASU may have on its consolidated financial statements and related disclosures.

Financial Instruments – Credit Losses. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) to replace the incurred loss impairment methodology under U.S. GAAP. This ASU introduces a new accounting model, the Current Expected Credit Losses model (CECL), which could result in earlier recognition of credit losses and additional disclosures related to credit risk. The CECL model will require the Company to use a forward-looking expected credit loss impairment methodology for the recognition of credit losses for financial instruments at the time the financial asset is originated or acquired, and require a loss be incurred before it is recognized. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. The new standard will apply to accounts receivable, loans, and other financial instruments. This standard is effective for the Company beginning January 1, 2023. Adoption of ASU 2016-13 will be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date. The Company is currently evaluating the impact of this ASU on our consolidated financial statements.

Goodwill. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350), simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates Step 2 of the goodwill impairment test. Goodwill impairment will now be the amount by which the reporting unit’s carrying amount exceeds its fair value, limited to the carrying amount of the goodwill. ASU 2017-04 is effective for us beginning January 1, 2022. The Company does not expect the impact of this ASU to be material to its consolidated financial statements.
