Debt Disclosure [Abstract]
LONG-TERM DEBT	LONG-TERM DEBT Accounts Receivable Securitization Facility On June 29, 2022, the Company, through a wholly-owned special purpose entity, Exact Receivables LLC (“Exact Receivables”) entered into an accounts receivable securitization program (the “Securitization Facility”) with PNC Bank, National Association (“PNC”), with a scheduled maturity date of June 29, 2024. The Securitization Facility provides Exact Receivables with a revolving line-of-credit of up to $150.0 million of borrowing capacity, subject to certain borrowing base requirements, by collateralizing a security interest in the domestic customer accounts receivable of certain wholly-owned subsidiaries of the Company. The amount available under the Securitization Facility fluctuates over time based on the total amount of eligible customer accounts receivable generated by the Company during the normal course of operations. The Securitization Facility requires the Company to maintain minimum borrowings under the facility of $50.0 million. The debt issuance costs incurred related to the Securitization Facility were not significant and are being amortized over the life of the Securitization Facility through interest expense within the consolidated statements of operations. In connection with the Securitization Facility, the Company also entered into two Receivables Purchase Agreements (“Receivable Purchase Agreements”) on June 29, 2022. The Receivable Purchase Agreements are among the Company and certain wholly-owned subsidiaries of the Company, and between the Company and Exact Receivables. Under the agreements, the wholly-owned subsidiaries sell all of their right, title and interest in their accounts receivables to Exact Receivables. The receivables are used to collateralize borrowings made under the Securitization Facility. The Company retains the responsibility of servicing the accounts receivable balances pledged as collateral under the Securitization Facility and provides a performance guaranty. As of December 31, 2023, the eligible borrowing base under the Securitization Facility was $108.5 million of which the Company elected to collateralize $50.0 million. As of December 31, 2023 and December 31, 2022, the Company had an outstanding balance of $50.0 million, which is included in debt, current portion and long-term debt, less current portion, respectively, on the Company’s consolidated balance sheets. The outstanding balance accrues interest at a rate equal to a daily secured overnight financing rate (“SOFR”) rate plus a SOFR adjustment and an applicable margin. The interest rate was 6.89% at December 31, 2023. Revolving Loan Agreement During November 2021, the Company entered into a revolving loan agreement (the “Revolving Loan Agreement”) with PNC. The Revolving Loan Agreement provides the Company with a revolving line of credit of up to $150.0 million (the “Revolver”). The Revolver is collateralized by the Company’s marketable securities held by PNC, which must continue to maintain a minimum market value of $150.0 million. The Revolver is available for general working capital purposes and all other lawful corporate purposes. In addition, the Company may request, in lieu of cash advances, letters of credit with an aggregate stated amount outstanding not to exceed $20.0 million. The availability of advances under the line of credit will be reduced by the stated amount of each letter of credit issued and outstanding. Borrowings under the Revolving Loan Agreement accrue interest at an annual rate equal to the sum of the daily Bloomberg Short-Term Bank Yield Index Rate plus the applicable margin of 0.60%. Loans under the Revolving Loan Agreement may be prepaid at any time without penalty. In October 2022 the Revolving Loan Agreement was amended to extend the maturity date from November 5, 2023 to November 5, 2025. There were no other amendments to the Revolver. The Company has agreed to various financial covenants under the Revolving Loan Agreement, and as of December 31, 2023, the Company is in compliance with all covenants. In December 2021 and January 2023, PNC issued letters of credit of $2.9 million and $1.5 million, respectively, which reduced the amount available for cash advances under the line of credit to $145.6 million and $147.1 million as of December 31, 2023 and December 31, 2022, respectively. As of December 31, 2023, the Company has not drawn funds from, nor are any amounts outstanding under, the Revolving Loan Agreement. Construction Loan Agreement During December 2017, the Company entered into a loan agreement with Fifth Third Bank (the “Construction Loan Agreement”), which provided the Company with a non-revolving construction loan (the “Construction Loan”) of $25.6 million- with a maturity date of December 10, 2022. The Company used the Construction Loan proceeds to finance the construction of an additional clinical laboratory and related facilities in Madison, Wisconsin. The Construction Loan was collateralized by the additional clinical laboratory and related facilities. The Construction Loan Agreement bore interest at a rate equal to the sum of the 1-month LIBOR rate plus 2.25%. The interest incurred on the Construction Loan was not significant and was capitalized to the construction project. The Company also incurred minimal debt issuance costs which were recorded as a direct deduction from the liability, and amortized over the life of the Construction Loan. As part of the Revolving Loan Agreement discussed above, the Company agreed to repay in full all outstanding debt owed to Fifth Third Bank under the Construction Loan Agreement, and as of December 31, 2021, the remaining outstanding balance had been fully repaid in connection with the termination of the Construction Loan Agreement. Any unamortized issuance costs at the time or repayment were recorded as a loss.
