Summary of Significant Accounting Policies

Basis of Presentation

The accompanying interim Consolidated Financial Statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information. All intercompany transactions and balances have been eliminated in the accompanying Consolidated Financial Statements.

The accounting policies of the Company are the same as those set forth in Note 2. Summary of Significant Accounting Policies, to the audited Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, except for Stock-based Compensation and new accounting standards discussed under Recent Accounting Pronouncements as referenced below.

Unaudited Interim Financial Information

Certain information and footnote disclosures normally included in the Company’s annual audited Consolidated Financial Statements and accompanying notes have been condensed or omitted in these accompanying interim Consolidated Financial Statements and footnotes. Accordingly, the accompanying interim unaudited Consolidated Financial Statements included herein should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

The results of operations presented in this Quarterly Report on Form 10-Q are not necessarily indicative of the results of operations that may be expected for any future periods. In the opinion of management, these unaudited Consolidated Financial Statements include all adjustments and accruals, consisting only of normal, recurring adjustments that are necessary for a fair statement of the results of all interim periods reported herein.

Use of Estimates

The Company prepares its Consolidated Financial Statements in conformity with GAAP. These principles require management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, together with amounts disclosed in the related notes to the Consolidated Financial Statements. Actual results and outcomes may differ from management’s estimates, judgments and assumptions. Significant estimates, judgments and assumptions used in these Consolidated Financial Statements include, but are not limited, to those related to revenues, accounts receivable and related allowances, contingencies, useful lives and recovery of long-term assets and intangible assets, income taxes and valuation allowances, stock-based compensation, impairment analysis of goodwill, and restructuring reserves. These estimates, judgments, and assumptions are reviewed periodically and the effects of material revisions in estimates are reflected on the Consolidated Financial Statements prospectively from the date of the change in estimate.

Segment Reporting

The Company has historically reported its activities in two reportable segments; (1) the Clinical Services segment and (2) the Pharma Services segment. In the second quarter of 2023, the Pharma Services segment was rebranded as the Advanced Diagnostics segment. Functions within the Clinical Services segment include oncology diagnostics, community-based oncology and pathology sales, patient engagement, and clinical decision support. Functions within the Advanced Diagnostics segment include pharma services, informatics, R&D, minimal residual disease, liquid biopsy and therapy selection business development. For further financial information regarding reportable segments, please refer to Note 13. Segment Information.

Sales and Marketing Expenses

Sales and marketing expenses are primarily attributable to employee-related costs including sales management, sales representatives, sales and marketing consultants, and marketing and customer service personnel in the Clinical Services segment. Advertising costs are expensed at the time they are incurred and were immaterial for the three and nine months ended September 30, 2023 and 2022.

Stock-based Compensation

In the second quarter of 2023, the Company began granting performance stock units (“PSUs”) subject to a market condition to certain of its executives as part of its executive compensation program. The number of shares awarded will be subject to adjustment based on the achievement of an absolute total shareholder return (“TSR”) performance target. If the TSR

performance target is achieved, the awards will vest at the end of the three-year requisite service period so long as the employee remains employed with the Company through the applicable vesting date.

The Company measures compensation expense for stock-based awards to employees, non-employee contracted physicians, and directors based upon the awards’ initial grant-date fair values. Stock-based compensation expense for stock options, restricted stock awards, restricted stock units and performance awards is recorded over the requisite service period in general and administrative expenses on the Consolidated Statements of Operations. For awards with only a service condition, the Company expenses stock-based compensation using the straight-line method over the requisite service period for the entire award. For awards with a market condition, the Company expenses the grant date fair value at the target over the vesting period regardless of the value that the award recipients ultimately receive. The fair values of stock option grants are estimated as of the date of grant by applying the Black-Scholes option valuation model (“Black-Scholes”). The fair value of restricted stock with a market condition is estimated at the date of grant using the Monte Carlo simulation model (“Monte Carlo”). The Black-Scholes and Monte Carlo models incorporate assumptions as to stock price volatility, the expected life of options or restricted stock, a risk-free interest rate and dividend yield. The fair value of restricted stock without a market condition is estimated using the current market price of the Company’s common stock on the date of grant.

Black-Scholes is affected by the stock price on the date of the grant as well as assumptions regarding a number of highly complex and subjective variables. These variables include the expected term of the option, expected risk-free interest rate, the expected volatility of common stock, and expected dividend yield; each of which is described below. The assumptions for expected term and expected volatility are the two assumptions that significantly affect the grant date fair value.

Expected Term: The expected term of an option is determined using the simplified method under SAB 107 which represents the average between the vesting term and the contractual term. The Company utilizes the simplified method to determine the expected life of the options due to insufficient exercise activity during recent years.

Risk-free Interest Rate: The risk-free interest rate used in the Black-Scholes model is based on the implied yield at the grant date of the U.S. Treasury zero-coupon issue with an equivalent term to the stock-based award being valued. Where the expected term of a stock-based award does not correspond with the term for which a zero-coupon interest rate is quoted, the Company uses the nearest interest rate from available maturities.

Expected Stock Price Volatility: The Company uses its own historical weekly volatility because that is more reflective of market conditions.

Dividend Yield: Because the Company has never paid a dividend and does not expect to begin doing so in the foreseeable future, the Company assumed no dividend yield in valuing the stock-based awards.

The fair value of the PSUs granted during the nine months ended September 30, 2023 was estimated as of the grant date using the Monte Carlo, which requires management to make assumptions regarding risk-free interest rates and volatility of the Company’s stock price. The Monte Carlo incorporates the same assumptions as Black-Scholes as to stock price volatility, the risk-free interest rate and dividend yield. The Company utilized the expected life of the PSUs for the expected term of the award, as the vesting term and contractual term of the awards are identical.

Recent Accounting Pronouncements

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update amends guidance to require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Revenue from Contracts with Customers (Topic 606). At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption of the amendments is permitted including adoption in an interim period. If the Company early adopts in an interim period, the Company is required to apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. The amendments in ASU 2021-08 should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company adopted this standard as of January 1, 2023 and there was no impact on its Consolidated Financial Statements.
