NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

NOTE 1 – NATURE OF BUSINESS AND BASIS OF PRESENTATION

We are a national provider of freestanding, fixed-site outpatient diagnostic imaging services in the United States. At March 31, 2024, we operated directly or indirectly through joint ventures with hospitals, 375 centers located in Arizona, California, Delaware, Florida, Maryland, New Jersey, and New York. Our centers provide physicians with imaging capabilities to facilitate the diagnosis and treatment of diseases and disorders. Our services include magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), nuclear medicine, mammography, ultrasound, diagnostic radiology (X-ray), fluoroscopy and other related procedures. The vast majority of our centers offer multi-modality imaging services. Our multi-modality strategy diversifies revenue streams, reduces exposure to reimbursement changes and provides patients and referring physicians one location to serve the needs of multiple procedures. In the first quarter of 2024, we revised our reportable segments to combine our eRad business, which was included in the Imaging Center segment, with our AI segment to form a new Digital Health reportable segment. Prior period amounts were adjusted retrospectively to reflect the change in reportable segment. For further financial information about these segments, see Note 5, Segment Reporting. In March 2024, we closed on a public offering of 5,232,500 shares of our common stock, including 682,500 shares sold pursuant to the exercise of an underwriter's overallotment option, at a price to the public of $44.00 per share. The gross proceeds as a result of this public offering was $230.2 million before underwriting discounts, commissions, and expenses totaling $11.8 million.

The consolidated financial statements include the accounts of RadNet, Inc as well as its subsidiaries in which RadNet has a controlling financial interest. The consolidated financial statements also include certain variable interest entities in which we are the primary beneficiary (as described in more detail below). All material intercompany transactions and balances have been eliminated upon consolidation. All of these affiliated entities are referred to collectively as “RadNet”, “we”, “us”, “our” or the “Company” in this report.

Accounting regulations stipulate that generally any entity with a) insufficient equity to finance its activities without additional subordinated financial support provided by any parties, or b) equity holders that, as a group, lack the characteristics which evidence a controlling financial interest, is considered a Variable Interest Entity (“VIE”). We consolidate all VIEs in which we are the primary beneficiary. We determine whether we are the primary beneficiary of a VIE through a qualitative analysis that identifies which variable interest holder has the controlling financial interest in the VIE. The variable interest holder who has both of the following has the controlling financial interest and is the primary beneficiary: (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. In performing our analysis, we consider all relevant facts and circumstances, including: the design and activities of the VIE, the terms of the contracts the VIE has entered into, the nature of the VIE’s variable interests issued and how they were negotiated with or marketed to potential investors, and which parties participated significantly in the design or redesign of the entity.

VIEs that we consolidate as the primary beneficiary include professional corporations which are owned or controlled by individuals within our senior management and provide professional medical services for centers in Arizona, California, Delaware, Maryland, New Jersey and New York. These VIEs are collectively referred to as the consolidated medical group ("the Group"). RadNet provides non-medical, technical and administrative services to the Group for which it receives a management fee, pursuant to the related management agreements. Through the management agreements we have exclusive authority over all non-medical decision making related to the ongoing business operations and we determine the annual budget. The Group has insignificant operating assets and liabilities, and de minimis equity. Substantially all cash flows of the Group after expenses, including professional salaries, are transferred to us. We consolidate the revenue and expenses, assets and liabilities of the Group. The creditors of the Group do not have recourse to our general credit and there are no other arrangements that could expose us to losses on behalf of the Group. However, RadNet may be required to provide financial support to cover any operating expenses in excess of operating revenues.

The Group on a combined basis recognized $52.3 million and $48.8 million of revenue, net of management services fees to RadNet, for the three months ended March 31, 2024 and 2023, respectively and $52.3 million and $48.8 million of operating expenses for the three months ended March 31, 2024 and 2023, respectively. RadNet recognized $234.8 million and $207.4 million of total billed net service fee revenue for the three months ended March 31, 2024, and 2023, respectively, for management services provided to the Group relating primarily to the technical portion of billed revenue.

The cash flows of the Group are included in the accompanying condensed consolidated statements of cash flows. All intercompany balances and transactions have been eliminated in consolidation. In our condensed consolidated balance sheets at March 31, 2024 and December 31, 2023, we have included approximately $108.9 million and $94.1 million, respectively, of

Table of Contents

accounts receivable and approximately $16.0 million and $16.7 million of accounts payable and accrued liabilities related to the Group, respectively.

At all of our centers not serviced by the Group we have entered into long-term contracts with medical groups to provide professional services at those centers, including supervision and interpretation of diagnostic imaging procedures. The medical groups maintain full control over the physicians they employ. Through our management agreements, we make available to the medical groups the imaging centers, including all furniture, fixtures and medical equipment therein. The medical groups are compensated for their services from the professional component of the global net service fee revenue and after deducting management service fees paid to us, we have no economic controlling interest in these medical groups. As such, the financial results of these groups are not consolidated in our financial statements.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X and, therefore, do not include all information and footnotes necessary for conformity with U.S. generally accepted accounting principles for complete financial statements; however, in the opinion of management, all adjustments consisting of normal recurring adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods ended March 31, 2024 and 2023 have been made. The results of operations for any interim period are not necessarily indicative of the results for a full year. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto contained in our annual report on Form 10-K for the year ended December 31, 2023.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

During the period covered in this report, there have been no material changes to the significant accounting policies we use and have explained, in our annual report on Form 10-K for the fiscal year ended December 31, 2023. The information below is intended only to supplement the disclosure in our annual report on Form 10-K for the fiscal year ended December 31, 2023.

REVENUES - Our revenues generally relate to net patient fees received from various payors and patients themselves under contracts in which our performance obligations are to provide diagnostic services to the patients. Revenues are recorded during the period when our obligations to provide diagnostic services are satisfied. Our performance obligations for diagnostic services are generally satisfied over a period of less than one day. The contractual relationships with patients, in most cases, also involve a third-party payor (Medicare, Medicaid, managed care health plans and commercial insurance companies, including plans offered through the health insurance exchanges) and the fees for the services provided are dependent upon the terms provided by Medicare and Medicaid, or negotiated with managed care health plans and commercial insurance companies. The payment arrangements with third-party payors for the services we provide to the related patients typically specify payments at amounts less than our standard charges and generally provide for payments based upon predetermined rates per diagnostic services or discounted fee-for-service rates. Management continually reviews the contractual estimation process to consider and incorporate updates to laws and regulations and the frequent changes in managed care contractual terms resulting from contract renegotiations and renewals.

As it relates to the Group, this service fee revenue includes payments for both the professional medical interpretation revenue recognized by the Group as well as the payment for all other aspects related to our providing the imaging services, for which we earn management fees. As it relates to others centers, this service fee revenue is earned through providing the use of our diagnostic imaging equipment and the provision of technical services as well as providing administration services such as clerical and administrative personnel, bookkeeping and accounting services, billing and collection, provision of medical and office supplies, secretarial, reception and transcription services, maintenance of medical records, and advertising, marketing and promotional activities.

Our revenues are based upon the estimated amounts we expect to be entitled to receive from patients and third-party payors. Estimates of contractual allowances under managed care and commercial insurance plans are based upon the payment terms specified in the related contractual agreements. Revenues related to uninsured patients and copayment and deductible amounts for patients who have health care coverage may have discounts applied (uninsured discounts and contractual discounts). We also record estimated implicit price concessions (based primarily on historical collection experience) related to uninsured accounts to record self-pay revenues at the estimated amounts we expect to collect.

Under capitation arrangements with various health plans, we earn a per-enrollee amount each month for making available diagnostic imaging services to all plan enrollees under the capitation arrangement. Revenue under capitation arrangements is recognized in the period in which we are obligated to provide services to plan enrollees under contracts with various health plans.

ACCOUNTS RECEIVABLE - Substantially all of our accounts receivable are due under fee-for-service contracts from third party payors, such as insurance companies and government-sponsored healthcare programs, or directly from patients. Services are generally provided pursuant to one-year contracts with healthcare providers. We continuously monitor collections from our payors and maintain an allowance for bad debts based upon specific payor collection issues that we have identified and our historical experience.

We have entered into factoring agreements with various institutions and sold certain accounts receivable under non-recourse agreements in exchange for notes receivables from the buyers. These transactions are accounted for as a reduction in accounts receivable as the agreements transfer effective control over and risk related to the receivables to the buyers. Proceeds on notes receivables are reflected as operating activities on our statement of cash flows and on our balance sheet as prepaid expenses and other current assets for the current portion and deposits and other for the long term portion. Amounts remaining to be collected on these agreements were $12.1 million and $14.3 million at March 31, 2024 and December 31, 2023, respectively. We do not utilize factoring arrangements as an integral part of our financing for working capital and assess the party's ability to pay upfront at the inception of the notes receivable and subsequently by reviewing their financial statements annually and reassessing any insolvency risk on a periodic basis.

DEFERRED FINANCING COSTS - Costs of financing are deferred and amortized using the effective interest rate method and are related to our revolving credit facilities. Deferred financing costs, net of accumulated amortization, were $1.5 million and $1.6 million, as of March 31, 2024 and December 31, 2023, respectively. See Note 6, Credit Facilities and Notes Payable for more information.

PROPERTY AND EQUIPMENT - Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation of property and equipment is performed using the straight-line method over the estimated useful lives of the assets acquired, which range from 3 to 15 years. Leasehold improvements are amortized at the lesser of lease term or their estimated useful lives, which range from 3 to 15 years. Maintenance and repairs are charged to expense as incurred.

BUSINESS COMBINATION - When the qualifications for business combination accounting treatment are met, it requires us to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.

Table of Contents

GOODWILL - Goodwill at March 31, 2024 totaled $694.3 million. Goodwill is recorded as a result of business combinations. If we determine the carrying value of a reporting unit exceeds its fair value an impairment charge would be recognized and should not exceed the total amount of goodwill allocated to that reporting unit. We tested goodwill and indefinite lived intangibles for impairment on October 1, 2023, noting no impairment. Activity in goodwill for the three months ended March 31, 2024 is provided below (in thousands):

INTANGIBLE ASSETS - Intangible assets are primarily related to our business combinations and software development. They include the estimated fair values of such items as service agreements, customer lists, covenants not to compete, acquired technologies, and trade names. The components of intangible assets, both finite and indefinite, along with annual amortization expense that will be recorded over the next five years at March 31, 2024 and December 31, 2023 are as follows (in thousands):

Total intangible asset amortization expense was $3.2 million and $3.0 million for the three months ended March 31, 2024 and March 31, 2023, respectively. Intangible assets are amortized using the straight-line method over their useful life determined at acquisition. Management service agreements are amortized over 25 years using the straight line method. Software development is capitalized and amortized over the useful life of the software when placed into service. Trade names are reviewed annually for impairment.

INCOME TAXES - Income tax expense is computed using an asset and liability method and using expected annual effective tax rates. Under this method, deferred income tax assets and liabilities result from temporary differences in the financial reporting bases and the income tax reporting bases of assets and liabilities. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefit that, based on available evidence, is not expected to be realized. When it appears more likely than not that deferred taxes will not be realized, a valuation allowance is recorded to reduce the deferred tax asset to its estimated realizable value. For net deferred tax assets we consider estimates of future taxable income in determining whether our net deferred tax assets are more likely than not to be realized.

In 2021, the Organization for Economic Co-operation and Development ("OECD") announced an inclusive framework on base erosion and profit shifting including Pillar Two Model Rules defining the global minimum tax, which calls for taxation of large multinational corporations at a minimum rate of 15%. Subsequently, multiple sets of administrative guidance have been issued. Many non-US tax jurisdictions have either recently enacted legislation to support certain components of Pillar Two Model Rules beginning 2024 (including the European Union Member States) with the adoption of additional components in later years or announced their plans to enact legislation in future years. The model rules provide a framework for applying the minimum tax, countries may enact Pillar Two Model Rules slightly differently than the model rules and on different timelines and may adjust domestic tax incentives in response to Pillar Two Model Rules. On a long-term basis, we will continue to evaluate the impacts of enacted legislation and pending legislation to enact Pillar Two Model Rules in all countries applicable to us. For 2024, we expect that we will meet one or more transactional safe harbor rules, and as such, we do not believe Pillar Two model will have an impact on our annual effective tax rate for the year ending December 31, 2024.

We recorded an income tax expense (benefit) of $(1.9) million, or an effective tax rate of (52.6)%, for the three months ended March 31, 2024 and $1.1 million, or an effective tax rate of (8.6)% for the three months ended March 31, 2023. The income tax rates for the three months ended March 31, 2024 diverge from the federal statutory rate due to (i) effects of state income taxes ; (ii) officer's compensation limitations; (iii) partial valuation allowance on losses in foreign jurisdictions, partially offset by (iv) excess tax benefits attributable to share based compensation; and (v) noncontrolling interests from controlled partnerships.

LEASES - We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and long term operating lease liability in our consolidated balance sheets. Finance leases are included in property and equipment, current finance lease liability, and long-term finance lease liability in our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. We include options to extend a lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For a contract in which we are a lessee that contains fixed

Table of Contents

payments for both lease and non-lease components, we have elected to account for the components as a single lease component. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the ROU asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. ROU assets are tested for impairment if circumstances suggest that the carrying amount may not be recoverable. Our ROU assets consist of facility and equipment assets on operating leases. No events have occurred such as fire, flood, or other acts which have impaired the integrity of our ROU assets as of March 31, 2024. Our facility leases require us to maintain insurance policies which would cover major damage to our facilities. We maintain business interruption insurance to cover loss of business due to a facility becoming non-operational under certain circumstances. Our equipment leases are covered by warranty and service contracts which cover repairs and provide regular maintenance to keep the equipment in functioning order.

EQUITY BASED COMPENSATION – We have one long-term incentive plan that we adopted in 2006 and which we have amended and restated at various points in time: first on April 20, 2015, second on March 9, 2017, third on April 15, 2021 and currently as of April 27, 2023 (the “Restated Plan”). The Restated Plan was approved by our stockholders at our annual stockholders meeting on June 7, 2023. We have reserved 20,100,000 shares of common stock for issuance under the Restated Plan which can be issued in the form of incentive and/or nonstatutory stock options, restricted and/or unrestricted stock, stock units, and stock appreciation rights. Terms and conditions of awards can be direct grants or based on achieving a performance metric. We evaluate performance-based awards to determine if it is probable that the vesting conditions will be met. We also consider probability of achievement of performance conditions when determining expense recognition. For the awards where vesting is probable, equity-based compensation is recognized over the related vesting period. Stock options generally vest over three years to five years and expire five years to ten years from date of grant. We determine the compensation expense for each stock option award using the Black Scholes, or similar valuation model. Those models require that our management make certain estimates concerning risk free interest rates and volatility in the trading price of our common stock. The compensation expense recognized for all equity-based awards is recognized over the awards’ service periods. Equity-based compensation is classified in operating expenses within the same line item as the majority of the cash compensation paid to employees. In connection with our acquisition of DeepHealth Inc. on June 1, 2020, we assumed the DeepHealth, Inc. 2017 Equity Incentive Plan, including outstanding options awards that can be exercised for our common stock. No additional awards will be granted under the DeepHealth, Inc. 2017 Equity Incentive Plan. See Note 7, Stock-Based Compensation, for more information.

COMPREHENSIVE INCOME (LOSS) - Accounting guidance establishes rules for reporting and displaying other comprehensive income (loss) and its components. Our foreign currency translation adjustments and the amortization of balances associated with derivatives previously classified as cash flow hedges are included in other comprehensive income (loss). The components of other comprehensive income (loss) for the three months ended March 31, 2024 and March 31, 2023 are included in the consolidated statements of comprehensive income (loss).

COMMITMENTS AND CONTINGENCIES - We are party to various legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. With respect to these matters, we evaluate the developments on a regular basis and accrue a liability when we believe a loss is probable and the amount can be reasonably estimated. Based on current information, we do not believe that reasonably possible or probable losses associated with pending legal proceedings would either individually or in the aggregate, have a material adverse effect on our business and consolidated financial statements. However, the outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against us for amounts in excess of management's expectations, our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable, could be materially adversely affected.

DERIVATIVE INSTRUMENTS - In the second quarter of 2019, we entered into four forward interest rate agreements ("2019 Swaps"). The 2019 Swaps have total notional amounts of $500.0 million, consisting of two agreements of $50.0 million each and two agreements of $200.0 million each. The 2019 Swaps will secure a constant interest rate associated with portions of our variable rate bank debt and have an effective date of October 13, 2020. They matured in October 2023 for the smaller notional and will mature in October 2025 for the larger notional. Under these arrangements, we arranged the 2019 Swaps with locked in 1 month Term SOFR rates at 1.89% for the $100.0 million notional and at 1.98% for the $400.0 million notional. As of the effective date, we are liable for premium payments if interest rates decline below arranged rates, but will receive interest payments if rates are above the arranged rates.

At inception, we designated our 2019 Swaps as cash flow hedges of floating-rate borrowings. In accordance with accounting guidance, derivatives that have been designated and qualify as cash flow hedging instruments are reported at fair value. The gain or loss on the effective portion of the hedge (i.e. change in fair value) is reported as a component of comprehensive gain or loss in the consolidated statement of equity. The remaining gain or loss, if any, is recognized currently in earnings. The cash flows for both our $400.0 million notional interest rate swap contract locked in at 1.98% due October 2025 and our $100.0 million notional interest rate swap contract locked in at 1.89% do not match the cash flows for our Term

Table of Contents

Loans (the “Barclays Term Loans”) under our Second Amended and Restated First Lien Credit and Guaranty Agreement with Barclays (the “Restated Credit Agreement”), and so we have determined that they are not currently effective as cash flow hedges. Accordingly, all changes in their fair value after April 1, 2020 for the $400.0 million notional and after July 1, 2020 for the $100.0 million notional are being recognized in earnings. As of July 1, 2020, the total change in fair value relating to swaps included in other comprehensive income was approximately $24.4 million, net of taxes. This amount was amortized to interest expense through October 2023 at approximately $0.4 million per month and continuing at approximately $0.3 million through October 2025.

CONTINGENT CONSIDERATION -

Heart and Lung Imaging Limited

On November 1, 2022, we completed our acquisition of 75% of the equity interests of Heart and Lung Imaging Limited. The purchase included up to $10.2 million in contingent milestone consideration and cash holdback of $0.6 million to be issued 24 months after acquisition subject to adjustment for any indemnification claims, which will be adjusted to fair value in subsequent periods. The milestone contingency had a value of approximately $4.2 million as of March 31, 2024. The contingent consideration is determined by the achievement of a specific number of physician reads. On September 20, 2023, we settled a milestone contingent liability by issuing 56,600 shares of our common stock at an ascribed value of $1.6 million and cash of $1.8 million. On December 12, 2023, we settled a milestone contingent liability by issuing 64,569 shares of our common stock at an ascribed value of $2.3 million and cash of $2.1 million. On March 27, 2024, we partially settled a milestone contingent liability by issuing 95,019 shares of our common stock at an ascribed value of $4.6 million. Subsequently on April 1, 2024, we settled the remaining milestone contingent liability in cash of $3.6 million.

A tabular rollforward of contingent consideration is as follows (amounts in thousands):

See Fair Value Measurements section below for the fair value of contingent consideration at March 31, 2024.

FAIR VALUE MEASUREMENTS – Assets and liabilities subject to fair value measurements are required to be disclosed within a fair value hierarchy. The fair value hierarchy ranks the quality and reliability of inputs used to determine fair value. Accordingly, assets and liabilities carried at, or permitted to be carried at, fair value are classified within the fair value hierarchy in one of the following categories based on the lowest level input that is significant to a fair value measurement:

Level 1—Fair value is determined by using unadjusted quoted prices that are available in active markets for identical assets and liabilities.

Level 2—Fair value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets and liabilities in inactive markets. Related inputs can also include those used in valuation or other pricing models such as interest rates and yield curves that can be corroborated by observable market data.

Level 3—Fair value is determined by using inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgment.

Derivatives:

The tables below summarize the estimated fair values of certain of our financial assets that are subject to fair value measurements, and the classification of these assets on our condensed consolidated balance sheets, as follows (in thousands):


	As of March 31, 2024
	Level 1		Level 2		Level 3		Total
Current and long term assets

	Level 1		Level 2		Level 3		Total
Current and long term assets

2019 Swaps - Interest Rate Contracts	$	—	$	15,118	$	—	$	15,118

The estimated fair value of these contracts was determined using Level 2 inputs. More specifically, the fair value was determined by calculating the value of the difference between the fixed interest rate of the interest rate swaps and the counterparty’s forward SOFR curve. The forward SOFR curve is readily available in the public markets or can be derived from information available in the public markets.

Contingent Consideration:

The table below summarizes the estimated fair values of contingencies and holdback relating to our Heart and Lung Imaging Limited acquisition on November 1, 2022 that are subject to fair value measurements and the classification of these liabilities on our consolidated balance sheets, as follows (in thousands):

Table of Contents

The estimated fair value of these liabilities was determined using Level 3 inputs. For Heart Lung Imaging Limited the contingent consideration is determined by the achievement of a specific number of physician reads. As significant inputs for the contingent consideration of Heart Lung Imaging Limited are not observable and cannot be corroborated by observable market data they are classified as Level 3.

Long Term Debt:

The table below summarizes the estimated fair value compared to our face value of our long-term debt as follows (in thousands):


	As of March 31, 2024
	Level 1		Level 2		Level 3		Total Fair Value		Total Face Value

Barclays Term Loans and Truist Term Loan	$	—	$	824,759	$	—	$	824,759	$	823,063

The estimated fair value of our long-term debt, which is discussed in Note 6, Credit Facilities and Notes Payable, was determined using Level 2 inputs primarily related to comparable market prices.

We consider the carrying amounts of cash and cash equivalents, receivables, other current assets, current liabilities and other notes payables to approximate their fair value because of the relatively short period of time between the origination of these instruments and their expected realization or payment.

EARNINGS PER SHARE - Earnings per share is based upon the weighted average number of shares of common stock and common stock equivalents outstanding, net of common stock held in treasury, as follows (in thousands except share and per share data):

INVESTMENTS IN EQUITY SECURITIES–Accounting guidance requires entities to measure equity investments at fair value, with any changes in fair value recognized in net income. If there is no readily determinable fair value, the guidance allows entities the ability to measure investments at cost, adjusted for observable price changes and impairments, with changes recognized in net income.

As of March 31, 2024, we have four equity investments for an aggregate of $9.2 million. No observable price changes or impairments in our investments were identified as of March 31, 2024.

INVESTMENT IN JOINT VENTURES – We have 13 unconsolidated joint ventures with ownership interests ranging from 35% to 55%. These joint ventures represent partnerships with hospitals, health systems or radiology practices and were formed for the purpose of owning and operating diagnostic imaging centers. Professional services at the joint venture diagnostic imaging centers are performed by contracted radiology practices or a radiology practice that participates in the joint venture. Our investment in these joint ventures is accounted for under the equity method, since RadNet does not have a controlling financial interest in such ventures. We evaluate our investment in joint ventures, including cost in excess of book value (equity method goodwill) for impairment whenever indicators of impairment exist. No indicators of impairment existed as of March 31, 2024.

Formation of majority owned subsidiary and sale of economic interest

On February 23, 2024, we formed Tri Valley Imaging Group, LLC ("TVIG"), a partnership with Providence Health System - Southern California ("PHS"). The operation offers multi-modality services out of seven locations in Southern California. On March 29, 2024, we contributed the operations of four centers to the enterprise and PHS contributed a business comprising three centers included $0.5 million fixed assets, $0.1 million in equipment and $6.5 million in goodwill. Simultaneously, PHS purchased from us an additional economic interest in TVIG for cash payment of $9.6 million. As a result of the transaction, we recognized a gain of $7.6 million to additional paid in capital and retained a 52% controlling economic interest in TVIG and PHS retains and $7.8 million or 48% noncontrolling economic interest in TVIG.

Joint venture investment contribution

In determining the fair value of the imaging centers contributed to TVIG, we used an income approach which is considered a level 3 valuation technique. See Fair Value Measurements above for further detail on the valuation hierarchy. Key assumptions used in measuring the fair value are financial forecasts and a discount rate. We also utilized the cash paid for an additional interest in the joint venture to substantiate the fair value of the contributed assets.

NOTE 5 – SEGMENT REPORTING

In the first quarter of 2024, we revised our reportable segments to combine our eRad business, which was included in the Imaging Center segment, with our AI segment to form a new Digital Health reportable segment. Prior period amounts were adjusted retrospectively to reflect the change in reportable segment.

Our reportable segments are described below:

Imaging Center

Our Imaging Center segment provides physicians with imaging capabilities to facilitate the diagnosis and treatment of diseases and disorders. Services include magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), nuclear medicine, mammography, ultrasound, diagnostic radiology (X-ray), fluoroscopy and other related procedures. The vast majority of our centers offer multi-modality imaging services, a strategy that diversifies revenue streams, reduces exposure to reimbursement changes and provides patients and referring physicians one location to serve the needs of multiple procedures.

Digital Health

Our Digital Health segment develops and deploys clinical applications to enhance interpretation of medical images and improve patient outcomes with an emphasis on brain, breast, prostate, and pulmonary diagnostics. Included in the segment is our eRad subsidiary, which designs the underlying critical scheduling, data storage and retrieval systems necessary for imaging center operation.

Our chief operating decision maker ("CODM"), who is also our CEO, evaluates the financial performance of our segments based upon their respective revenue and segmented internal profit and loss statements prepared on a basis not consistent with GAAP. We do not report balance sheet information by segment since it is not reviewed by our CODM.

In the normal course of business, our reportable segments enter into transactions with each other. While intersegment transactions are treated like third-party transactions to determine segment performance, the revenues recognized by a segment and expenses incurred by the counterparty are eliminated in consolidation and do not affect consolidated results.

NOTE 7 – STOCK-BASED COMPENSATION

Stock Incentive Plans

We have one long-term equity incentive plan, the RadNet, Inc. Equity Incentive Plan, which we first amended and restated April 20, 2015, second on March 9, 2017, third on April 15, 2021, and currently as of April 27, 2023 (the "Restated Plan”). The Restated Plan was most recently approved by our stockholders at our annual stockholders meeting on June 7, 2023. We have reserved for issuance under the Restated Plan 20,100,000 shares of common stock. We can issue options (incentive and nonstatutory), performance based options, stock awards (restricted or unrestricted), stock units, performance based stock units, and stock appreciation rights under the Restated Plan.

Options

Certain options granted under the Restated Plan to employees are intended to qualify as incentive stock options under existing tax regulations. Stock options generally vest over 3 to 5 years and expire 5 to 10 years from the date of grant.

The following summarizes all of our option transactions for the three months ended March 31, 2024:


Outstanding Options Under the 2006 Plan	Shares	Weighted Average Exercise price Per Common Share		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value
Balance, December 31, 2023	911,411	$	16.60

Table of Contents

Aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between our closing stock price on March 31, 2024 and the exercise price, multiplied by the number of in-the-money options as applicable) that would have been received by the holder had all holders exercised their options on March 31, 2024. As of March 31, 2024, total unrecognized stock-based compensation expense related to non-vested employee awards was $1.1 million, which is expected to be recognized over a weighted average period of approximately 0.88 years.

DeepHealth Options

During the second quarter of fiscal 2020, in connection with the completion of the DeepHealth acquisition, we granted options to acquire 412,434 shares at a grant date fair value of $16.93 per share unit to DeepHealth employees in replacement of their stock options that were outstanding as of the closing date. As of March 31, 2024, total unrecognized stock based compensation expense related to non-vested DeepHealth options was insignificant.

Overview

We are a national provider of diagnostic imaging services in the United States. At March 31, 2024, we operated directly or indirectly through joint ventures with hospitals, 375 centers located in Arizona, California, Delaware, Florida, Maryland, New Jersey, and New York. Our centers provide physicians with imaging capabilities to facilitate the diagnosis and treatment of diseases and disorders and may reduce unnecessary invasive procedures, often reducing the cost and amount of care for patients. Internationally, our subsidiary Heart and Lung Imaging LLC, provides teleradiology services for remote interpretation of images on behalf of providers within the framework of the United Kingdom's National Health Service.

In addition to our imaging business, we have established a Digital Health business segment for our 2024 fiscal year, which combines our former Artificial Intelligence (“AI”) business segment with our eRad, Inc. business. Prior period amounts have been adjusted retrospectively to reflect the change in reportable segment.

Table of Contents

RadNet’s digital health segment develops and delivers AI-powered health informatics solutions to drive quality, efficiency, and outcomes in imaging and radiology. The portfolio of software solutions are anchored by eRad, Inc.'s RIS/PACS, informatics designed specifically for outpatient radiology and DeepHealth OS, a cloud-native operating system that helps operate all aspects of the radiology service line. DeepHealth OS addresses challenges across the entire value chain from scheduling and patient preparation to technologist workflow to interpretation and referral management.

Our current AI focus for clinical workflows is to develop solutions that employ machine learning to assist radiologists and other clinicians in interpreting images and improving radiologist efficiency and patient care, initially in the fields of screening for breast, prostate, lung and colon cancers. Our DeepHealth, Inc. subsidiary has received FDA clearance for use of its SaigeQ ”triage”/workflow product, SaigeDX advanced diagnostic product and Saige-Density breast density assessment software for screening breast mammography, which we have begun to roll out in certain markets as an Enhanced Breast Cancer Detection solution. Our Aidence subsidiary is focused on developing solutions for interpretation of chest and lung CT scans for lung cancer screening. It has received the CE mark for its solution and has existing customers in seven European countries, with its largest concentration in the United Kingdom, and plans to submit an application for FDA clearance to sell in the United States. Our Quantib subsidiary is primarily focused on interpretation of prostate MRI for widespread prostate cancer screening. Quantib’s prostate MRI post-processing software has both FDA clearances and European CE marking. The digital health segment provides these solutions to RadNet and to over 400 customers in the United States, Europe, and Israel.

Our operations comprise two segments for financial reporting purposes for this reporting period, Imaging Centers and Digital Health. For further financial information about these segments, see Note 5, Segment Reporting, in the notes accompanying our financial statements included in this report.

Recent Developments

The following table shows our imaging centers in operation and revenues for the three months ended March 31, 2024 and 2023:

Critical Accounting Policies

The Securities and Exchange Commission defines critical accounting estimates as those that (a) are most important to the portrayal of a company’s financial condition and results of operations and (b) require management’s most difficult, subjective or complex judgment, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. In Note 2 to our financial statements included in this report and in our annual report on Form 10-K for the year ended December 31, 2023, we discuss our significant accounting policies, including those that do not require management to make difficult, subjective or complex judgments or estimates. The most significant areas involving management’s judgments and estimates are described below.

Use of Estimates

The financial statements included in this report were prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions affect various matters, including our reported amounts of assets and liabilities in our consolidated balance sheets at the dates of the financial statements; our disclosure of contingent assets and liabilities at the dates of the financial statements; and our reported amounts of revenues and expenses in our consolidated statements of operations during the reporting periods. These estimates involve judgments with respect to numerous factors that are difficult to predict and are beyond management’s control. As a result, actual amounts could materially differ from these estimates.

Revenues

Our revenues generally relate to net patient fees received from various payors and patients themselves under contracts in which our performance obligations are to provide diagnostic services to the patients. Revenues are recorded during the period our obligations to provide diagnostic services are satisfied. Our performance obligations for diagnostic services are generally satisfied over a period of less than one day. The contractual relationships with patients, in most cases, also involve a third-party payor (Medicare, Medicaid, managed care health plans and commercial insurance companies, including plans offered through the health insurance exchanges) and the transaction prices for the services provided are dependent upon the terms provided by (Medicare and Medicaid) or negotiated with (managed care health plans and commercial insurance companies) the third-party payors. The payment arrangements with third-party payors for the services we provide to the related patients typically specify payments at amounts less than our standard charges and generally provide for payments based upon predetermined rates per diagnostic services or discounted fee-for-service rates. Management continually reviews the contractual estimation process to consider and incorporate updates to laws and regulations, changes in business and economic conditions, and the frequent changes in managed care contractual terms resulting from contract re-negotiations and renewals.

As it relates to the Group, this service fee revenue includes payments for both the professional medical interpretation revenue recognized by them as well as the payment for all other aspects related to our providing the imaging services, for which we earn management fees. As it relates to others centers, this service fee revenue is earned through providing the use of our diagnostic imaging equipment and the provision of technical services as well as providing administration services such as clerical and administrative personnel, bookkeeping and accounting services, billing and collection, provision of medical and

office supplies, secretarial, reception and transcription services, maintenance of medical records, and advertising, marketing and promotional activities.

Our revenues are based upon our management's estimate of amounts we expect to be entitled to receive from patients and third-party payors. Estimates of contractual allowances under Medicare, Medicaid, managed care and commercial insurance plans are based upon historical collection experience of the payments received from such payors in accordance with the underlying contractual agreements. Revenues related to uninsured patients and uninsured copayment and deductible amounts for patients who have health care coverage may have price concessions applied. We also record estimated implicit price concessions (based primarily on historical collection experience) related to uninsured accounts to record self-pay revenues at the estimated amounts we expect to collect.

Accounts Receivable

Substantially all of our accounts receivable are due under fee-for-service contracts from third party payors, such as insurance companies and government-sponsored healthcare programs, or directly from patients. Services are generally provided pursuant to one-year contracts with healthcare providers. Receivables generally are collected within industry norms for third-party payors. We continuously monitor collections from our payors and maintain an allowance for bad debts based upon specific payor collection issues that we have identified and our historical experience. Our estimates and assumptions for allowances on our account receivable did not change materially during the quarter ended March 31, 2024.

Business Combination

We evaluate all acquisitions under the framework Clarifying the Definition of a Business in the accounting guidance. Once a purchase has been determined to be the acquisition of a business, we are required to recognize the assets acquired and the liabilities assumed at their acquisition date fair values. Any portion of the purchase consideration transferred in excess of the net of the acquisition date fair values of the assets acquired and the liabilities assumed, is allocated to goodwill. The allocation requires our management to make estimates of the value of various assets acquired and liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.

Goodwill and Indefinite Lived Intangibles

Goodwill at March 31, 2024 totaled $694.3 million. Indefinite Lived Intangible Assets at March 31, 2024 were $20.2 million and are associated with the value of certain trade name intangibles and in process research and development (IPR&D). Goodwill, trade name intangibles and IPR&D are recorded as a result of business combinations. When we determine the carrying value of goodwill exceeds its fair value, an impairment charge would be recognized which should not exceed the total amount of goodwill allocated to that reporting unit. We determined fair values for each of the reporting units using the market approach, when available and appropriate, or the income approach, or a combination of both. We assess the valuation methodology based upon the relevance and availability of the data at the time we perform the valuation. If multiple valuation methodologies are used, the results are weighted appropriately.

Our annual test of goodwill, trade name noted no impairment as of October 1, 2023, and we have not identified any other indicators of impairment through March 31, 2024.

Three Months Ended March 31, 2024 Compared to the Three Months Ended March 31, 2023

Imaging Center Segment

We have developed our medical imaging centers segment through a combination of organic growth, equity investments, acquisitions and joint venture formations. In the discussion below same center metrics are based on imaging centers that were in operation throughout the period of January 1, 2024 through March 31, 2024. Excluded amounts relate to imaging centers that were acquired or divested between January 1, 2024 through March 31, 2024.

Total Revenue

Same Center Revenue	$376,655	$348,240	$28,415	8.2%
Excluded	$40,391	$31,247	—	—

Our 8.2% increase in same center revenue over the same period last year was driven by same center total procedure volume growth of 1.6% which was comprised of a 0.5% increase in routine imaging and a 5.1% increase in advanced modality imaging procedures. The balance of increase related to product mix, as advanced imaging was a greater portion of overall procedures, as well as increases in rates charged for imaging procedures.

Operating Expenses

Total operating expenses for the three months ended March 31, 2024 increased approximately $32.4 million, or 8.7%, from $370.3 million for the three months ended March 31, 2023 to $402.7 million for the three months ended March 31, 2024. The following table sets forth a breakdown of our cost of operations and total operating expenses for the three months ended March 31, 2024 and 2023 (in thousands):

Same Center Salaries	$228,105	$201,280	$26,825	13.3%
Excluded	$16,611	$13,376	—	—

Consistent with the higher procedure volumes noted above, our staffing levels were adjusted to support the influx of patients seeking radiology procedures. We are continuing to face inflation in employee wage rates as we compete for talent in a tight labor market.

Stock-based compensation

Stock-based compensation for the three months ended March 31, 2024 decreased approximately $0.5 million, or 4.0%, from $11.5 million for the three months ended March 31, 2023 to $11.1 million for the three months ended March 31, 2024. The decrease is primarily a result of a smaller number of shares granted in the first quarter of 2024, partially offset by higher fair value of stock awards granted and vested in the first quarter of 2024.

Building and equipment rental

Severance	$225	$122	103	84.2%

The fair value of the 2019 swaps at March 31, 2024 was a net asset of $16.3 million compared to a net asset of $15.1 million December 31, 2023, resulting in a gain of $1.2 million during the three months ended March 31, 2024, which increased the Company’s tax provision by $0.2 million. The change in fair value related to reduced expectations that market interest rates would decrease during the remaining term of the 2019 swaps.

Other income for the three months ended March 31, 2024 included money market interest income of $4.4 million.

Interest expense


In Thousands	Three Months Ended March 31,

*Includes payments from 2019 swaps

**Includes noncash amortization of deferred loan costs and discount on issuance of debt

***Includes interest related to our term loans, revolving credit line, notes, and other

The increase in interest expense was the result in the general increase in interest rates compared to the same period in the prior year, partially offset by payments from our 2019 swaps.

To mitigate our future floating rate interest expense exposure we entered into the 2019 swaps with locked in interest rates for one-month Term SOFR of 1.89% for $100 million of notional value and 1.98% for $400 million of notional value. We are liable for premium payments to the 2019 swap counterparties if interests rates are below the arranged rates, and receive payments from the 2019 swap counterparties if interest rates exceed the arranged rates. If interest rates were to theoretically reduce to 0%, our maximum premium payment would be the difference between the two swapped rates and 0% then multiplied by the notional value of the swaps, or $1.89 million per year for the $100 million swap and $8.0 million per year for the $400 million swap. Payments under the 2019 swaps are settled in cash on a monthly basis.

During the three months ended March 31, 2024, interest rates were above the arranged rates for most of the year and we received payment of $3.4 million in cash payments from our 2019 swap counterparties, which was reported a component of interest expense. See the Derivative Instruments section of Note 2, Summary of Significant Accounting Policies, in the notes accompanying in our annual report on Form 10-K for the fiscal year ended December 31, 2023 and Part 1, Item 3 — "Quantitative and Qualitative Disclosure About Market Risk" below for more details on our derivative transactions.

Equity in earnings from unconsolidated joint ventures

For the three months ended March 31, 2024 and 2023 we recognized equity in earnings from unconsolidated joint ventures in the amount of $4.3 million and $1.4 million, respectively, an increase of $2.9 million or 202.8%. The increase was mainly due to the additional contribution made to SMIG in September 2023. SMIG operated at a net income for the three

months ended March 31, 2024, which positively impacted our equity in earnings from unconsolidated joint ventures during the period.

Net income attributable to noncontrolling interests

At March 31, 2024, our consolidated subsidiaries operated 323 imaging centers of which 85 were not wholly-owned and thus a portion of their operating results were attributable to noncontrolling interests. At March 31, 2023, our consolidated subsidiaries included 324 centers of which 83 were not wholly-owned.

For the three months ended March 31, 2024, we recognized net income attributable to noncontrolling interests of $8.2 million versus $6.7 million for the three months ended March 31, 2023, an increase of $1.6 million. The increase in net income attributable to noncontrolling interests was primarily due to the formation of a new majority owned subsidiary, Los Angeles Imaging Group, LLC in September 2023. We contributed the operations of three centers to Los Angeles Group, LLC and Cedars-Sinai Medical Center contributed cash. Additionally, patient volumes for advanced modalities improved in 2024 and we closed two nonperforming centers in a majority owned subsidiary, Beach Imaging Group, LLC in December 2023.

As noncontrolling interests only represent a portion of our imaging center business, and excludes our Digital Health Segment which generated losses of $3.0 million for the three months ended March 31, 2024, we do not expect changes in net income attributable to noncontrolling interests to correlate with changes in consolidated operating income or pretax income.

Digital Health Segment

The breakdown of revenue and expenses of the segment for the three months ended March 31, 2024 and 2023 are as follows:

Segment net loss	(3,686)		(4,470)		784		(17.5)	%

Revenues for the digital health segment increased as a result of core growth in our eRad PICS business, the rollout in 2023 of our Deephealth OS, and continued rollout of our Enhanced Breast Cancer Detection solutions across additional facilities. The increase in operating expenses was primarily related to salary expense as we increased headcount in connection with the commercialization of our initial AI products. Our net loss for the segment was consistent with the prior year. We expect that our Digital Health segment will continue to generate net losses over the next several years.

Non-GAAP Financial Measures

We use both GAAP and non-GAAP metrics to measure our financial results. We believe that, in addition to GAAP metrics, non-GAAP metrics such as Adjusted EBITDA assist us in measuring our core operations from period to period.

Table of Contents

Adjusted EBITDA

Our Adjusted EBITDA metric removes non-cash and non-recurring charges that occur in the affected period and provides a basis for measuring the Company’s core financial performance against other periods.

We define Adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, as adjusted to exclude losses or gains on the disposal of equipment, other income or loss, loss on debt extinguishment, bargain purchase gains, loss on de-consolidation of joint ventures, gain on contribution of imaging centers into joint ventures, and non-cash equity compensation. Adjusted EBITDA includes equity earnings in unconsolidated operations and subtracts allocations of earnings to non-controlling interests in subsidiaries, and is adjusted for non-cash or one-time events that take place during the period.

Adjusted EBITDA is a non-GAAP financial measure used as an analytical indicator by us and the healthcare industry to assess business performance. Adjusted EBITDA should not be considered a measure of financial performance under GAAP, and Adjusted EBITDA should not be considered in isolation or as alternatives to net income, or other financial statement data presented in the consolidated financial statements as an indicator of financial performance. Adjusted EBITDA is not a measurement determined in accordance with GAAP and is therefore susceptible to varying methods of calculation and this metric, as presented, may not be comparable to other similarly titled measures of other companies.

The following is a reconciliation of the nearest comparable GAAP financial measure, net income, to Adjusted EBITDA for the three months ended March 31, 2024 and 2023, respectively.

Liquidity and Capital Resources

We expect our existing capital resources, anticipated cash from operations and our borrowing capacity under our credit facilities will be sufficient to sustain our operations for the next twelve months and the foreseeable future.

Our principal capital requirements are for the initial start-up and development of new diagnostic imaging centers, the acquisition of additional centers and the acquisition of new diagnostic imaging equipment. On a continuing basis, we evaluate various transactions to increase shareholder value and enhance our business results, including acquisitions, divestitures and joint ventures. We expect to fund any future acquisitions primarily with cash flow from operations and borrowings, including borrowing from amounts available under our senior secured credit facilities or through new equity or debt issuances.

We and our subsidiaries or affiliates may from time to time, in our sole discretion, purchase, repay, redeem or retire any of our outstanding debt or equity securities in privately negotiated or open market transactions, by tender offer or otherwise.

The following table summarizes key balance sheet data related to our liquidity as of March 31, 2024 and December 31, 2023 and income statement data for the three months ended March 31, 2024 and 2023 (in thousands):

Sources and Uses of Cash

The following table summarizes key components of our sources and uses of cash for the three months ended March 31, 2024 and 2023 (in thousands):

Table of Contents


Cash Flow Data	March 31, 2024		March 31, 2023
Cash provided by (used in) operating activities	$	17,085	$	32,616
Cash provided by (used in) investing activities	(60,937)		(65,556)
Cash provided by (used in) financing activities	228,298		(3,821)

Cash provided by operating activities for the three months ended March 31, 2024 decreased by $15.5 million compared to March 31, 2023 primarily driven by the timing of payments, as a $17.8 million increase in net income was offset by a $51.7 million change in assets and liabilities, primarily related to a pay down of accounts receivable and accrued expenses.

Cash used in investing activities for the three months ended March 31, 2024 decreased from March 31, 2023 by $4.6 million. Purchases of imaging centers during the period was $3.5 million, a $6.1 million decrease from the prior period. Capital expenditures for property and equipment during the period was $57.4 million, a $1.5 million increase from the prior period.

Cash provided by financing activities for the three months ended March 31, 2024 related primarily to a secondary public offering of our common stock, offset by payments including prepayments on our term loan, and payments of contingent consideration on recent acquisition transactions. In March 2024, we completed a public offering of 5,232,500 shares of our common stock, which included 682,500 shares sold pursuant to an underwriters overallotment option, at a price to the public of $44.00 per share, resulting in net proceeds after underwriting discounts, commissions, and expenses of $218.3 million. Additional cash provided by financing activities included $8.7 million received from sale of economic interest in majority owned subsidiary and a $4.2 million contribution from noncontrolling partners.

Senior Secured Credit Facilities

We maintain secured credit facilities with Barclays Bank PLC and with Truist Bank. Our condensed consolidated balance sheets at March 31, 2024 include $821.2 million of total term loan debt (exclusive of unamortized discounts of $10.6 million) in thousands:


	Face Value		Discount		Total Carrying Value
Barclays Term Loan	$	678,687	$	(8,519)	$	670,168
Truist Term Loan	142,500		(924)		141,576
Total Term Loans	$	821,187	$	(9,443)	$	811,744

At March 31, 2024, we had no borrowings under our Barclays or Truist revolving credit facilities. After reserves for outstanding letters of credit of $7.6 million, we had $187.4 million available for borrowing under our Barclays revolving credit facility and $50.0 million available under our Truist revolving credit facility.

On April 18, 2024, after the period covered by this report, we refinanced our Barclays term loan and credit facility, replacing the prior facility with an $875.0 million term loan and a $282.0 million revolving credit facility. The refinance transaction reduced out interest rates on the Barclays term loan and revolving credit facility and extended the maturity date for the term loan to April 18, 2031 and for the revolving credit facility to April 18, 2029. The new term loan calls for quarterly principal payments of $2.2 million, compared to $1.8 million under the prior credit facility. After paying off the balance on the prior facility, payment of accrued interest through the closing of the refinance transaction, and payment of transaction fees and expenses, we added approximately $167.9 million in cash to the balance sheet. Please see Note 6, Credit Facilities and Notes Payable in the notes to financial statements included in this report for more information on our secured credit facilities.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Foreign Currency Exchange Risk:

We are exposed to foreign exchange risk with respect to revenues and expenses denominated in the Pound Sterling, Euro, Canadian Dollar and Hungarian Forint. We provide radiological services in the United Kingdom, conduct Artificial Intelligence operations in the Netherlands, and maintain research and development centers in Canada and Hungary. We do not have any foreign currency exchange contracts to mitigate this risk. At March 31, 2024, a hypothetical 1% decline in the currency exchange rates between the U.S. dollar against these currencies, would have resulted in an annual increase of approximately $0.3 million in operating expenses.

Interest Rate Sensitivity:

Our debt instruments including borrowings under our Barclays term loan and revolving credit facility and our Truist term loan and revolving credit facility bear interest at variable rates. Accordingly, our interest expense and consequently, our earnings, are affected by changes in short term interest rates. We purchased the 2019 swaps to mitigate interest rate risk on a portion of our outstanding term loan debt as described below.

We can elect SOFR or Alternative Base Rate interest options on amounts outstanding under the Barclays Term Loans. At March 31, 2024, after giving effect to the $400 million notional amount of our 2019 swaps we had $278.7 million outstanding subject to a SOFR election and our effective rate plus applicable margin was 8.57%. A hypothetical 1% increase in the SOFR rates under the Barclay's credit facility would result in an increase of $1.2 million in annual interest expense and a corresponding decrease in income before taxes. The 2019 Swaps secure a 1 month Term SOFR rate of 1.98% for the $400 million notional amount.

We can elect SOFR or Base Rate interest rate options on amounts outstanding under the Truist credit facility. At March 31, 2024, we had $142.5 million outstanding subject to an adjusted SOFR election on the Truist term loan. At March 31, 2024, our effective SOFR rate plus applicable margin was 6.93%. A hypothetical 1% increase in the adjusted Eurodollar rates under the Truist credit facility would result in an increase of approximately $1.4 million in annual interest expense and a corresponding decrease in income before taxes.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures under Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, as of March 31, 2024. Based on this evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2024 to provide reasonable assurance that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during three months ended March 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

NATURE OF BUSINESS AND BASIS OF PRESENTATION	3 Months Ended
NATURE OF BUSINESS AND BASIS OF PRESENTATION	Mar. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF BUSINESS AND BASIS OF PRESENTATION	NATURE OF BUSINESS AND BASIS OF PRESENTATION We are a national provider of freestanding, fixed-site outpatient diagnostic imaging services in the United States. At March 31, 2024, we operated directly or indirectly through joint ventures with hospitals, 375 centers located in Arizona, California, Delaware, Florida, Maryland, New Jersey, and New York. Our centers provide physicians with imaging capabilities to facilitate the diagnosis and treatment of diseases and disorders. Our services include magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), nuclear medicine, mammography, ultrasound, diagnostic radiology (X-ray), fluoroscopy and other related procedures. The vast majority of our centers offer multi-modality imaging services. Our multi-modality strategy diversifies revenue streams, reduces exposure to reimbursement changes and provides patients and referring physicians one location to serve the needs of multiple procedures. In the first quarter of 2024, we revised our reportable segments to combine our eRad business, which was included in the Imaging Center segment, with our AI segment to form a new Digital Health reportable segment. Prior period amounts were adjusted retrospectively to reflect the change in reportable segment. For further financial information about these segments, see Note 5, Segment Reporting. In March 2024, we closed on a public offering of 5,232,500 shares of our common stock, including 682,500 shares sold pursuant to the exercise of an underwriter's overallotment option, at a price to the public of $44.00 per share. The gross proceeds as a result of this public offering was $230.2 million before underwriting discounts, commissions, and expenses totaling $11.8 million. The consolidated financial statements include the accounts of RadNet, Inc as well as its subsidiaries in which RadNet has a controlling financial interest. The consolidated financial statements also include certain variable interest entities in which we are the primary beneficiary (as described in more detail below). All material intercompany transactions and balances have been eliminated upon consolidation. All of these affiliated entities are referred to collectively as “RadNet”, “we”, “us”, “our” or the “Company” in this report. Accounting regulations stipulate that generally any entity with a) insufficient equity to finance its activities without additional subordinated financial support provided by any parties, or b) equity holders that, as a group, lack the characteristics which evidence a controlling financial interest, is considered a Variable Interest Entity (“VIE”). We consolidate all VIEs in which we are the primary beneficiary. We determine whether we are the primary beneficiary of a VIE through a qualitative analysis that identifies which variable interest holder has the controlling financial interest in the VIE. The variable interest holder who has both of the following has the controlling financial interest and is the primary beneficiary: (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. In performing our analysis, we consider all relevant facts and circumstances, including: the design and activities of the VIE, the terms of the contracts the VIE has entered into, the nature of the VIE’s variable interests issued and how they were negotiated with or marketed to potential investors, and which parties participated significantly in the design or redesign of the entity. VIEs that we consolidate as the primary beneficiary include professional corporations which are owned or controlled by individuals within our senior management and provide professional medical services for centers in Arizona, California, Delaware, Maryland, New Jersey and New York. These VIEs are collectively referred to as the consolidated medical group ("the Group"). RadNet provides non-medical, technical and administrative services to the Group for which it receives a management fee, pursuant to the related management agreements. Through the management agreements we have exclusive authority over all non-medical decision making related to the ongoing business operations and we determine the annual budget. The Group has insignificant operating assets and liabilities, and de minimis equity. Substantially all cash flows of the Group after expenses, including professional salaries, are transferred to us. We consolidate the revenue and expenses, assets and liabilities of the Group. The creditors of the Group do not have recourse to our general credit and there are no other arrangements that could expose us to losses on behalf of the Group. However, RadNet may be required to provide financial support to cover any operating expenses in excess of operating revenues. The Group on a combined basis recognized $52.3 million and $48.8 million of revenue, net of management services fees to RadNet, for the three months ended March 31, 2024 and 2023, respectively and $52.3 million and $48.8 million of operating expenses for the three months ended March 31, 2024 and 2023, respectively. RadNet recognized $234.8 million and $207.4 million of total billed net service fee revenue for the three months ended March 31, 2024, and 2023, respectively, for management services provided to the Group relating primarily to the technical portion of billed revenue. The cash flows of the Group are included in the accompanying condensed consolidated statements of cash flows. All intercompany balances and transactions have been eliminated in consolidation. In our condensed consolidated balance sheets at March 31, 2024 and December 31, 2023, we have included approximately $108.9 million and $94.1 million, respectively, of accounts receivable and approximately $16.0 million and $16.7 million of accounts payable and accrued liabilities related to the Group, respectively. At all of our centers not serviced by the Group we have entered into long-term contracts with medical groups to provide professional services at those centers, including supervision and interpretation of diagnostic imaging procedures. The medical groups maintain full control over the physicians they employ. Through our management agreements, we make available to the medical groups the imaging centers, including all furniture, fixtures and medical equipment therein. The medical groups are compensated for their services from the professional component of the global net service fee revenue and after deducting management service fees paid to us, we have no economic controlling interest in these medical groups. As such, the financial results of these groups are not consolidated in our financial statements. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X and, therefore, do not include all information and footnotes necessary for conformity with U.S. generally accepted accounting principles for complete financial statements; however, in the opinion of management, all adjustments consisting of normal recurring adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods ended March 31, 2024 and 2023 have been made. The results of operations for any interim period are not necessarily indicative of the results for a full year. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto contained in our annual report on Form 10-K for the year ended December 31, 2023.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
SIGNIFICANT ACCOUNTING POLICIES (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
REVENUES	REVENUES - Our revenues generally relate to net patient fees received from various payors and patients themselves under contracts in which our performance obligations are to provide diagnostic services to the patients. Revenues are recorded during the period when our obligations to provide diagnostic services are satisfied. Our performance obligations for diagnostic services are generally satisfied over a period of less than one day. The contractual relationships with patients, in most cases, also involve a third-party payor (Medicare, Medicaid, managed care health plans and commercial insurance companies, including plans offered through the health insurance exchanges) and the fees for the services provided are dependent upon the terms provided by Medicare and Medicaid, or negotiated with managed care health plans and commercial insurance companies. The payment arrangements with third-party payors for the services we provide to the related patients typically specify payments at amounts less than our standard charges and generally provide for payments based upon predetermined rates per diagnostic services or discounted fee-for-service rates. Management continually reviews the contractual estimation process to consider and incorporate updates to laws and regulations and the frequent changes in managed care contractual terms resulting from contract renegotiations and renewals. As it relates to the Group, this service fee revenue includes payments for both the professional medical interpretation revenue recognized by the Group as well as the payment for all other aspects related to our providing the imaging services, for which we earn management fees. As it relates to others centers, this service fee revenue is earned through providing the use of our diagnostic imaging equipment and the provision of technical services as well as providing administration services such as clerical and administrative personnel, bookkeeping and accounting services, billing and collection, provision of medical and office supplies, secretarial, reception and transcription services, maintenance of medical records, and advertising, marketing and promotional activities. Our revenues are based upon the estimated amounts we expect to be entitled to receive from patients and third-party payors. Estimates of contractual allowances under managed care and commercial insurance plans are based upon the payment terms specified in the related contractual agreements. Revenues related to uninsured patients and copayment and deductible amounts for patients who have health care coverage may have discounts applied (uninsured discounts and contractual discounts). We also record estimated implicit price concessions (based primarily on historical collection experience) related to uninsured accounts to record self-pay revenues at the estimated amounts we expect to collect. Under capitation arrangements with various health plans, we earn a per-enrollee amount each month for making available diagnostic imaging services to all plan enrollees under the capitation arrangement. Revenue under capitation arrangements is recognized in the period in which we are obligated to provide services to plan enrollees under contracts with various health plans.
ACCOUNTS RECEIVABLE	ACCOUNTS RECEIVABLE - Substantially all of our accounts receivable are due under fee-for-service contracts from third party payors, such as insurance companies and government-sponsored healthcare programs, or directly from patients. Services are generally provided pursuant to one-year contracts with healthcare providers. We continuously monitor collections from our payors and maintain an allowance for bad debts based upon specific payor collection issues that we have identified and our historical experience. We have entered into factoring agreements with various institutions and sold certain accounts receivable under non-recourse agreements in exchange for notes receivables from the buyers. These transactions are accounted for as a reduction in accounts receivable as the agreements transfer effective control over and risk related to the receivables to the buyers. Proceeds on notes receivables are reflected as operating activities on our statement of cash flows and on our balance sheet as prepaid expenses and other current assets for the current portion and deposits and other for the long term portion.We do not utilize factoring arrangements as an integral part of our financing for working capital and assess the party's ability to pay upfront at the inception of the notes receivable and subsequently by reviewing their financial statements annually and reassessing any insolvency risk on a periodic basis.
DEFERRED FINANCING COSTS	DEFERRED FINANCING COSTS - Costs of financing are deferred and amortized using the effective interest rate method and are related to our revolving credit facilities.
PROPERTY AND EQUIPMENT	PROPERTY AND EQUIPMENT - Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation of property and equipment is performed using the straight-line method over the estimated useful lives of the assets acquired, which range from 3 to 15 years. Leasehold improvements are amortized at the lesser of lease term or their estimated useful lives, which range from 3 to 15 years. Maintenance and repairs are charged to expense as incurred.
BUSINESS COMBINATION	BUSINESS COMBINATION - When the qualifications for business combination accounting treatment are met, it requires us to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.
GOODWILL	GOODWILLGoodwill is recorded as a result of business combinations. If we determine the carrying value of a reporting unit exceeds its fair value an impairment charge would be recognized and should not exceed the total amount of goodwill allocated to that reporting unit. We tested goodwill and indefinite lived intangibles for impairment on October 1, 2023, noting no impairment.
INCOME TAXES	INCOME TAXES - Income tax expense is computed using an asset and liability method and using expected annual effective tax rates. Under this method, deferred income tax assets and liabilities result from temporary differences in the financial reporting bases and the income tax reporting bases of assets and liabilities. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefit that, based on available evidence, is not expected to be realized. When it appears more likely than not that deferred taxes will not be realized, a valuation allowance is recorded to reduce the deferred tax asset to its estimated realizable value. For net deferred tax assets we consider estimates of future taxable income in determining whether our net deferred tax assets are more likely than not to be realized.
LEASES	LEASES - We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and long term operating lease liability in our consolidated balance sheets. Finance leases are included in property and equipment, current finance lease liability, and long-term finance lease liability in our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. We include options to extend a lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For a contract in which we are a lessee that contains fixed payments for both lease and non-lease components, we have elected to account for the components as a single lease component. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the ROU asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. ROU assets are tested for impairment if circumstances suggest that the carrying amount may not be recoverable. Our ROU assets consist of facility and equipment assets on operating leases. No events have occurred such as fire, flood, or other acts which have impaired the integrity of our ROU assets as of March 31, 2024. Our facility leases require us to maintain insurance policies which would cover major damage to our facilities. We maintain business interruption insurance to cover loss of business due to a facility becoming non-operational under certain circumstances. Our equipment leases are covered by warranty and service contracts which cover repairs and provide regular maintenance to keep the equipment in functioning order.
EQUITY BASED COMPENSATION	EQUITY BASED COMPENSATION – We have one long-term incentive plan that we adopted in 2006 and which we have amended and restated at various points in time: first on April 20, 2015, second on March 9, 2017, third on April 15, 2021 and currently as of April 27, 2023 (the “Restated Plan”). The Restated Plan was approved by our stockholders at our annual stockholders meeting on June 7, 2023. We have reserved 20,100,000 shares of common stock for issuance under the Restated Plan which can be issued in the form of incentive and/or nonstatutory stock options, restricted and/or unrestricted stock, stock units, and stock appreciation rights. Terms and conditions of awards can be direct grants or based on achieving a performance metric. We evaluate performance-based awards to determine if it is probable that the vesting conditions will be met. We also consider probability of achievement of performance conditions when determining expense recognition. For the awards where vesting is probable, equity-based compensation is recognized over the related vesting period. Stock options generally vest over three years to five years and expire five years to ten years from date of grant. We determine the compensation expense for each stock option award using the Black Scholes, or similar valuation model. Those models require that our management make certain estimates concerning risk free interest rates and volatility in the trading price of our common stock. The compensation expense recognized for all equity-based awards is recognized over the awards’ service periods. Equity-based compensation is classified in operating expenses within the same line item as the majority of the cash compensation paid to employees. In connection with our acquisition of DeepHealth Inc. on June 1, 2020, we assumed the DeepHealth, Inc. 2017 Equity Incentive Plan, including outstanding options awards that can be exercised for our common stock. No additional awards will be granted under the DeepHealth, Inc. 2017 Equity Incentive Plan. See Note 7, Stock-Based Compensation, for more information.
COMPREHENSIVE INCOME (LOSS)	COMPREHENSIVE INCOME (LOSS) - Accounting guidance establishes rules for reporting and displaying other comprehensive income (loss) and its components. Our foreign currency translation adjustments and the amortization of balances associated with derivatives previously classified as cash flow hedges are included in other comprehensive income (loss). The components of other comprehensive income (loss) for the three months ended March 31, 2024 and March 31, 2023 are included in the consolidated statements of comprehensive income (loss).
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES - We are party to various legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. With respect to these matters, we evaluate the developments on a regular basis and accrue a liability when we believe a loss is probable and the amount can be reasonably estimated. Based on current information, we do not believe that reasonably possible or probable losses associated with pending legal proceedings would either individually or in the aggregate, have a material adverse effect on our business and consolidated financial statements. However, the outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against us for amounts in excess of management's expectations, our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable, could be materially adversely affected.
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTSThe 2019 Swaps will secure a constant interest rate associated with portions of our variable rate bank debt and have an effective date of October 13, 2020. They matured in October 2023 for the smaller notional and will mature in October 2025 for the larger notional.As of the effective date, we are liable for premium payments if interest rates decline below arranged rates, but will receive interest payments if rates are above the arranged rates.At inception, we designated our 2019 Swaps as cash flow hedges of floating-rate borrowings. In accordance with accounting guidance, derivatives that have been designated and qualify as cash flow hedging instruments are reported at fair value. The gain or loss on the effective portion of the hedge (i.e. change in fair value) is reported as a component of comprehensive gain or loss in the consolidated statement of equity.
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS – Assets and liabilities subject to fair value measurements are required to be disclosed within a fair value hierarchy. The fair value hierarchy ranks the quality and reliability of inputs used to determine fair value. Accordingly, assets and liabilities carried at, or permitted to be carried at, fair value are classified within the fair value hierarchy in one of the following categories based on the lowest level input that is significant to a fair value measurement: Level 1—Fair value is determined by using unadjusted quoted prices that are available in active markets for identical assets and liabilities. Level 2—Fair value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets and liabilities in inactive markets. Related inputs can also include those used in valuation or other pricing models such as interest rates and yield curves that can be corroborated by observable market data. Level 3—Fair value is determined by using inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgment. The estimated fair value of these contracts was determined using Level 2 inputs. More specifically, the fair value was determined by calculating the value of the difference between the fixed interest rate of the interest rate swaps and the counterparty’s forward SOFR curve. The forward SOFR curve is readily available in the public markets or can be derived from information available in the public markets. The estimated fair value of our long-term debt, which is discussed in Note 6, Credit Facilities and Notes Payable, was determined using Level 2 inputs primarily related to comparable market prices. We consider the carrying amounts of cash and cash equivalents, receivables, other current assets, current liabilities and other notes payables to approximate their fair value because of the relatively short period of time between the origination of these instruments and their expected realization or payment.
EARNINGS PER SHARE	EARNINGS PER SHARE - Earnings per share is based upon the weighted average number of shares of common stock and common stock equivalents outstanding, net of common stock held in treasury, as follows (in thousands except share and per share data):
INVESTMENTS IN EQUITY SECURITIES	INVESTMENTS IN EQUITY SECURITIES–Accounting guidance requires entities to measure equity investments at fair value, with any changes in fair value recognized in net income. If there is no readily determinable fair value, the guidance allows entities the ability to measure investments at cost, adjusted for observable price changes and impairments, with changes recognized in net income.
INVESTMENTS IN JOINT VENTURES	INVESTMENT IN JOINT VENTURES – We have 13 unconsolidated joint ventures with ownership interests ranging from 35% to 55%. These joint ventures represent partnerships with hospitals, health systems or radiology practices and were formed for the purpose of owning and operating diagnostic imaging centers. Professional services at the joint venture diagnostic imaging centers are performed by contracted radiology practices or a radiology practice that participates in the joint venture. Our investment in these joint ventures is accounted for under the equity method, since RadNet does not have a controlling financial interest in such ventures. We evaluate our investment in joint ventures, including cost in excess of book value (equity method goodwill) for impairment whenever indicators of impairment exist. No indicators of impairment existed as of March 31, 2024.
RECENT ACCOUNTING AND REPORTING STANDARDS	Recently Issued Accounting Pronouncements We monitor new accounting pronouncements issued by the Financial Accounting Standards Board ("FASB") and do not believe any accounting pronouncements issued through the date of this report will have a material impact on our financial statements.
