SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES |
Principles of Consolidation | Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Zynex, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates | Use of Estimates Preparation of financial statements in conformity with 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 revenue and expenses during the reporting period. Actual results could differ from those estimates. The most significant management estimates used in the preparation of the accompanying condensed consolidated financial statements are associated with the allowance for billing adjustments and uncollectible accounts receivable, the reserve for obsolete and damaged inventory, stock-based compensation, assumptions related to the valuation of contingent consideration, and valuation of long-lived assets and realizability of deferred tax assets.
Cash, Cash Equivalents, and Short-Term Investments | Cash, Cash Equivalents, and Short-Term Investments Cash equivalents consist of highly liquid investments with remaining maturities of three months or less at the date of purchase. We classify investments with maturities of greater than three months but less than one year as short-term investments. Short-term investments are classified as held-to-maturity as the Company has the positive intent and ability to hold the investments until maturity. Held-to-maturity investments are carried at amortized cost. Due to the short-term nature, the carrying amounts reported in the consolidated balance sheet approximate fair value.
Accounts Receivable, Net | Accounts Receivable, Net The Company’s accounts receivable represent unconditional rights to consideration and are generated when a patient receives one of the Company’s devices, related supplies or complementary products. In conjunction with fulfilling the Company’s obligation to deliver a product, the Company invoices the patient’s third-party payer and/or the patient. Billing adjustments represent the difference between the list price and the reimbursement rates set by third-party payers, including Medicare, commercial payers and amounts billed directly to the patient. Specific amounts, if uncollected over a period of time, may be written-off after several appeals, which in some cases may take longer than twelve months. Substantially all of the Company’s receivables are due from patients with commercial or government health plans and workers compensation claims with a smaller portion related to private pay individuals, attorney, and auto claims. The Company maintains a constraint for third-party payer refund requests, deductions and adjustments. See Note 15 – Concentrations for discussion of significant customer accounts receivable balances.
Inventory, Net | Inventory, Net Inventories are stated at the lower of cost or net realizable value. Cost is computed using standard costs, which approximates actual costs on an average cost basis. The Company monitors inventory for turnover and obsolescence and records losses for excess and obsolete inventory, as appropriate. The Company provides reserves for estimated excess and obsolete inventories based upon assumptions about future demand. If future demand is less favorable than currently projected by management, additional inventory write-downs may be required.
Long-lived Assets | Long-lived Assets The Company records intangible assets based on estimated fair value on the date of acquisition. Long-lived assets consist of net property and equipment and intangible assets. The finite-lived intangible assets are patents and are amortized on a straight-line basis over the estimated lives of the assets. The Company assesses impairment of long-lived assets when events or changes in circumstances indicates that their carrying value amount may not be recoverable. Circumstances which could trigger a review include, but are not limited to: (i) significant decreases in the market price of the asset; (ii) significant adverse changes in the business climate or legal or regulatory factors; (iii) or, expectations that the asset will more likely than not be sold or disposed of significantly before the end of its estimated useful life. If the estimated future undiscounted cash flows, excluding interest charges, from the use of an asset are less than the carrying value, a write-down would be recorded to reduce the related asset to its estimated fair value. Useful lives of finite-lived intangible assets by each asset category are summarized below: ​
​ | ​ | ​
​ | ​ | Estimated
​ | ​ | Useful Lives
​ |  | in years
Patents |  | 11
Goodwill | Goodwill Goodwill is recorded as the difference between the fair value of the purchase consideration and the estimated fair value of the net identifiable tangible and intangible assets acquired. Goodwill is not subject to amortization but is subject to impairment testing. The Company utilizes the simplified test for goodwill impairment. The amount recognized for impairment is equal to the difference between the carrying value and the asset’s fair value. The valuation methods used in the quantitative fair value assessment was a discounted cash flow method and required management to make certain assumptions and estimates regarding certain industry trends and future profitability of our reporting units. The Company tests more frequently if indicators are present or changes in circumstances suggest that impairment may exist. These indicators include, among others, declines in sales, earnings or cash flows, or the development of a material adverse change in the business climate. The Company assesses goodwill for impairment at the reporting unit level. The estimates of fair value and the determination of reporting units requires management judgment.
Revenue Recognition | Revenue Recognition Revenue is derived from sales and leases of the Company’s electrotherapy devices and sales of related supplies and complementary products. Device sales can be in the form of a purchase or a lease. Supplies needed for the device can be set up as a recurring shipment or ordered through the customer support team or online store as needed. The Company recognizes revenue when the performance obligation has been met and the product has been transferred to the patient, in the amount that reflects the consideration the Company expects to receive. In general, revenue from sales of devices and supplies is recognized once the product is delivered to the patient, which is when the performance obligation has been met and the product has been transferred to the patient. Sales of devices and supplies are primarily shipped directly to the patient, with a small amount of revenue generated from sales to distributors. In the healthcare industry there is often a third party involved that will pay on the patients’ behalf for purchased or leased devices and supplies. The terms of the separate arrangement impact certain aspects of the contracts, with patients covered by third party payers, such as contract type, performance obligations and transaction price, but for purposes of revenue recognition the contract with the customer refers to the arrangement between the Company and the patient. The Company does not have any material deferred revenue in the normal course of business as each performance obligation is met upon delivery of goods to the patient. There are no substantial costs incurred through support or warranty obligations. The following table provides a breakdown of disaggregated net revenues for the three and nine months ended September 30, 2023 and 2022 related to devices accounted for as purchases subject to Accounting Standards Codification (“ASC”) 606 – “Revenue from Contracts with Customers” (“ASC 606”), leases subject to ASC 842 – “Leases” (“ASC 842”), and supplies (in thousands):

Purchased | ​ | $ | 7,022 | ​ | $ | 2,900 | ​ | $ | 16,444 | ​ | $ | 7,357 | ​
Leased | ​ |  | 9,833 | ​ |  | 8,449 | ​ |  | 26,098 | ​ |  | 20,222 | ​
Total device revenue | ​ | $ | 16,855 | ​ | $ | 11,349 | ​ | $ | 42,542 | ​ | $ | 27,579 | ​
Supplies revenue | ​ | ​ | 33,060 | ​ | ​ | 30,171 | ​ | ​ | 94,495 | ​ | ​ | 81,783 | ​
Total revenue | ​ | $ | 49,915 | ​ | $ | 41,520 | ​ | $ | 137,037 | ​ | $ | 109,362 | ​
​ Revenues are estimated using the portfolio approach by third-party payer type based upon historical rates of collection, aging of receivables, trends in historical reimbursement rates by third-party payer types, and current relationships and experience with the third-party payers, which includes estimated constraints for third-party payer refund requests, deductions and adjustments. Inherent in these estimates is the risk that they will have to be revised as additional information becomes available and constraints are released. Specifically, the complexity of third-party payer billing arrangements and the uncertainty of reimbursement amounts for certain products from third-party payers or unanticipated requirements to refund payments previously received may result in adjustments to amounts originally recorded. Settlements with third-party payers for retroactive revenue adjustments due to audits, reviews or investigations are considered variable consideration and are included in the determination of the estimated transaction price using the expected amount method. These adjustments to transaction price are estimated based on the terms of the payment agreement with the payer, correspondence from the payer and historical settlement activity, including an assessment to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustment is subsequently resolved. Due to continuing changes in the healthcare industry and third-party payer reimbursement, it is possible the Company’s forecasting model to estimate collections could change, which could have an impact on the Company’s results of operations and cash flows. Any differences between estimated and actual collectability are reflected in the period in which received. Historically these differences have been immaterial, and the Company has not had a significant reversal of revenue from prior periods. The Company monitors the variability and uncertain timing over third-party payer types in the portfolios. If there is a change in the Company’s third-party payer mix over time, it could affect net revenue and related receivables. The Company believes it has a sufficient history of collection experience to estimate the net collectible amounts by third-party payer type. However, changes to constraints related to billing adjustments and refund requests have historically fluctuated and may continue to fluctuate significantly from quarter to quarter and year to year.
Leases | Leases The Company determines if an arrangement is a lease at inception or modification of a contract. The Company recognizes finance and operating lease right-of-use assets and liabilities at the lease commencement date based on the estimated present value of the remaining lease payments over the lease term. For the finance leases, the Company uses the implicit rate to determine the present value of future lease payments. For operating leases that do not provide an implicit rate, the Company uses incremental borrowing rates to determine the present value of future lease payments. The Company includes options to extend or terminate a lease in the lease term when it is reasonably certain to exercise such options. The Company recognizes leases with an initial term of 12 months or less as lease expense over the lease term and those leases are not recorded on the Company’s condensed consolidated balance sheets. For additional information on the leases where the Company is the lessee, see Note 14 - Leases. A significant portion of device revenue is derived from patients who obtain devices under month-to-month lease arrangements where the Company is the lessor. Revenue related to devices on lease is recognized in accordance with ASC 842. Using the guidance in ASC 842, the Company concluded the transactions should be accounted for as operating leases based on the following criteria below:
| ● | The lease does not transfer ownership of the underlying asset to the lessee by the end of the lease term.
| ● | The lease does not grant the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise.
| ● | The lease term is month to month, which does not meet the major part of the remaining economic life of the underlying asset. However, if the commencement date falls at or near the end of the economic life of the underlying asset, this criterion shall not be used for purposes of classifying the lease.
| ● | There is no residual value guaranteed and the present value of the sum of the lease payments does not equal or exceed substantially all of the fair value of the underlying asset
| ● | The underlying asset is expected to have alternative uses to the lessor at the end of the lease term.
Lease commencement occurs upon delivery of the device to the patient. The Company retains title to the leased device and those devices are classified as property and equipment on the balance sheet. Since the leases are month-to-month and can be returned by the patient at any time, revenue is recognized monthly for the duration of the period in which the patient retains the device.
Debt Issuance Costs | Debt Issuance Costs Debt issuance costs are costs incurred to obtain new debt financing. Debt issuance costs are presented in the accompanying condensed consolidated balance sheets as a reduction in the carrying value of the debt and are accreted to interest expense using the effective interest method.
Stock-based Compensation | Stock-based Compensation The Company accounts for stock-based compensation through recognition of the cost of employee services received in exchange for an award of equity instruments, which is measured based on the grant date fair value of the award that is ultimately expected to vest during the period. The stock-based compensation expenses are recognized over the period during which an employee is required to provide service in exchange for the award (the requisite service period, which in the Company’s case is the same as the vesting period). For awards subject to the achievement of performance metrics, stock-based compensation expense is recognized when it becomes probable that the performance conditions will be achieved over the respective performance period.
Segment Information | Segment Information The Company defines operating segments as components of the business enterprise for which separate financial information is reviewed regularly by the chief operating decision-makers to evaluate performance and to make operating decisions. The Company has identified our Chief Executive Officer, Chief Financial Officer, and Chief Operating Officer as our Chief Operating Decision-Makers (“CODM”). The Company currently operates business as one operating segment which includes two revenue types: Devices and Supplies.
Income Taxes | Income Taxes The Company records deferred tax assets and liabilities for the estimated future tax effects of temporary differences between the tax bases of assets and liabilities and amounts reported in the accompanying condensed consolidated balance sheets, as well as operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance if, based on available evidence, it is more likely than not that these benefits will not be realized. Tax benefits are recognized from uncertain tax positions if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The Inflation Reduction Act (“IRA”) was enacted into law on August 16, 2022. Included in the IRA was a provision to implement a 15% corporate alternative minimum tax on corporations whose average annual adjusted financial statement income during the most recently completed three year period exceeds $1 billion. This provision is effective for tax years beginning after December 31, 2022. We are in the process of evaluating the provisions of the IRA, but we do not currently believe the IRA will have a material impact on our reported results, cash flows or financial position when it becomes effective.
Recent Accounting Pronouncements | Recent Accounting Pronouncements On October 9, 2023, the Financial Accounting Standards Board (“FASB”) issued ASU (“Accounting Standards Update”) 2023-06 which amends the disclosure or presentation requirements related to various subtopics in the FASB ASC. The amendments in ASU 2023-06 modify the disclosure or presentation requirements of a variety of Topics in the ASC. Certain of the amendments represent clarifications to or technical corrections of the current requirements. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. For all entities, if by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. Management is evaluating the impacts of the recently issued ASU. Management does not believe that any other recently issued accounting pronouncements will have a material impact on the Company’s consolidated financial statements.
