NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(US Dollars in thousands, except share data)

Note 1. Description of the Business

Overview of the Business

The Oncology Institute, Inc. (“TOI”) is the successor entity to DFP Healthcare Acquisitions Corp. ("DFPH"). DFPH is a Delaware corporation originally formed in 2019 as a publicly-traded special purpose acquisition company for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination ("Business Combination"). TOI was originally founded in 2007 and is a community oncology practice that operates value-based oncology services platforms. TOI has various wholly-owned subsidiaries, including The Oncology Institute, LLC ("TOI LLC") (which was formerly known as TOI Parent, Inc.), The Oncology Institute of Hope and Innovation Patient Safety Organization, LLC, and TOI Management, LLC (“TOI Management”). Additionally, TOI Management holds master services agreements with affiliated physician-owned professional entities ("TOI PCs") that confer controlling financial interest over the professional entities and their wholly-owned subsidiaries (TOI PCs, together with TOI, the “Company”).

On November 12, 2021 ("Closing Date"), the Business Combination closed following a series of mergers, which resulted in DFPH emerging as the parent of the combined entity Orion Merger Sub II, LLC and the former TOI Parent, Inc. (together, "Legacy TOI"). DFPH was renamed “The Oncology Institute, Inc.” and common stock and "Public Warrants" continued to be listed on Nasdaq under the ticker symbols “TOI” and “TOIIW,” respectively (See Note 16).

Operationally, the Company’s medical centers provide a complete suite of medical oncology services including: physician services, in-house infusion and pharmacy, clinical trials, radiation, educational seminars, support groups, counseling, and 24/7 patient assistance. TOI’s mission is to heal and empower cancer patients through compassion, innovation and state-of-the-art medical care. The Company brings comprehensive, integrated cancer care into the community setting, including clinical trials, palliative care programs, stem cell transplants, and other care delivery models traditionally associated with non-community-based academic and tertiary care settings. In addition, the Company, through its consolidating subsidiary TOI Clinical Research, LLC ("TCR"), performs cancer clinical trials through a network of cancer care specialists. TCR conducts clinical trials for a broad range of pharmaceutical and medical device companies from around the world.

The Company has approximately 112 oncologists and mid-level professionals across 70 clinic locations located within five states: California, Florida, Arizona, Nevada, and Texas. The Oncology Institute CA, a Professional Corporation ("TOI CA"), one of the TOI PCs, has clinic locations in California, Nevada, and Arizona. The Company has contractual relationships with multiple payors, serving Medicare, including Medicare Advantage, Medi-Cal, and commercial patients.

Note 2. Summary of Significant Accounting Policies

Unaudited Interim Financial Information

The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and note disclosures required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. However, the Company believes that the disclosures are adequate to ensure the information is not misleading. In the opinion of management, all adjustments (of normal and recurring nature) considered necessary for fair presentation have been reflected in these interim condensed consolidated financial statements. As such, the information included in the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes as of, and for the year ended December 31, 2022, issued on March 16, 2023.

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of TOI, its subsidiaries, all of which are controlled by TOI through majority voting control, and variable interest entities (“VIE”) for which TOI (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation.

11

Table of Contents

Variable Interest Entities

The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and net income from these subsidiaries are included in the consolidated amounts as presented on the Condensed Consolidated Statements of Operations.

The Company holds variable interests in TOI PCs, which it cannot legally own, as a result of entering into master services agreements ("MSAs"). As of September 30, 2023, TOI held variable interests in TOI CA, The Oncology Institute FL, LLC, a Professional Corporation ("TOI FL"), and The Oncology Institute TX, a Professional Corporation ("TOI TX"), all of which are VIEs. The Company is the primary beneficiary of the TOI PCs and thus, consolidates the TOI PCs in its financial statements. As discussed in Note 17, the shareholders of the Company's consolidating VIEs own a minority of the issued and outstanding common shares of the Company.

Business Combinations

The Company accounts for all transactions that represent business combinations using the acquisition method of accounting under Accounting Standards Codification ("ASC") Topic No. 805, Business Combinations (“ASC 805”). The Company first assesses whether an acquisition constitutes a business combination or asset acquisition by applying the screening test and analyzing whether the acquired entity has substantive inputs, processes, and the ability to produce outputs. Upon concluding an acquisition is a business combination, per ASC 805, the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquired entity are recognized and measured at their fair values on the date an entity obtains control of the acquiree. Such fair values that are not finalized for reporting periods following the acquisition date are estimated and recorded as provisional amounts. Adjustments to these provisional amounts during the measurement period (defined as the date through which all information required to identify and measure the consideration transferred, the assets acquired, the liabilities assumed, and the noncontrolling interests obtained, limited to one year from the acquisition date) are recorded when identified. Goodwill is determined as the excess of the fair value of the consideration exchanged in the acquisition over the fair value of the net assets acquired.

The DFPH-Legacy TOI Business Combination was accounted for as a reverse recapitalization. Under this method of accounting, DFPH was treated as the “acquired” company for accounting purposes and the Business Combination was treated as the equivalent of Legacy TOI issuing stock for the net assets of DFPH, accompanied by a recapitalization. The net assets of DFPH are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination were those of TOI LLC.

Segment Reporting

The Company presents the financial statements by segment in accordance with ASC Topic No. 280, Segment Reporting (“ASC 280”) to provide investors with transparency into how the chief operating decision maker (“CODM”) manages the business. The Company determined the CODM is its Chief Executive Officer. The CODM reviews financial information and allocates resources across three operating segments: patient services, dispensary, and clinical trials & other. Each of the operating segments is also a reporting segment as described further in Note 20.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates under different assumptions or conditions. Significant items subject to such estimates and assumptions include judgements related to revenue recognition, estimated accounts receivable and the allowance for credit losses, useful lives and recoverability of long-lived and intangible assets, recoverability of goodwill, fair values of acquired identifiable assets and assumed liabilities in business combinations, fair value of intangible assets and goodwill, fair value of share-based compensation, fair value of liability classified instruments, and judgements related to deferred income taxes.

Net Income (Loss) Per Share

Basic and diluted net income (loss) per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company's Series A Convertible Preferred Stock is classified as a

12

Table of Contents

participating security in accordance with ASC 260. Under the two-class method, basic and diluted net income (loss) per share attributable to common stockholders is computed by dividing the basic and diluted net income (loss) attributable to common stockholders by the basic and diluted weighted-average number of shares of common stock outstanding during the period. Diluted net income per share attributable to common stockholders adjusts basic net income per share for the potentially dilutive impact of stock options, restricted stock units, Medical RSUs (defined in Note 14), earnout shares (defined in Note 14), public warrants, private placement warrants, and Senior Secured Convertible Notes (defined in Note 11).

The treasury stock method is used to calculate the potentially dilutive effect of stock options, RSUs, public warrants, and private placement warrants. The if-converted method is used to calculate the potentially dilutive effect of the Senior Secured Notes. In both methods, diluted net income (loss) attributable to common stockholders and diluted weighted-average shares outstanding are adjusted to account for the impact of the assumed issuance of potential common shares that are dilutive, subject to dilution sequencing rules. The earnout shares are contingently issuable; therefore, the earnout shares are excluded from basic and diluted net income (loss) per share until the market conditions have been met (see more detail on the earnout shares in Note 14). The Medical RSUs (defined in Note 14) are also contingently issuable; therefore, they are excluded from basic net income (loss) per share until the performance and service conditions have been met (see more detail in Note 14). Further, the number of contingently issuable Medical RSUs included in diluted net income (loss) per share is based on the number of shares, if any, that would be issuable if the end of the reporting period were the end of the contingency period and if the result would be dilutive. For the periods presented, the public and private placement warrants are out of the money; therefore, the public and private placement warrants are antidilutive and excluded from diluted net income per share.

Fair Value Measurements

The Company accounts for fair value measurements under ASC Topic No. 820, Fair Value Measurements (“ASC 820”). The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels (see Note 7 for further discussion):

Level 1inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The Company's fair value measurement methodology for cash and cash equivalents, accounts receivable, other receivables, and accounts payable approximates fair value because of the short maturity and high liquidity of these instruments. Fair value measurement of investment securities available for sale is based upon quoted prices from active markets, if available (Level 1). If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation methodologies. Level 2 investment securities include US Treasuries purchased in the secondary market that use pricing inputs other than quoted prices in active markets and fair value is determined using pricing models or other valuation methodologies such as broker price indications, which are based on quoted prices for identical or similar notes, which are Level 2 input measures. Fair value measurements of derivative warrants are based on the market price of our public warrants, which are quoted prices for similar instruments and considered a Level 2 input. Fair value measurements of earnout liabilities are based on the Monte-Carlo Simulation Model, which is considered to be a Level 3 fair value measurement. The primary unobservable input utilized in determining the fair value of the earnouts is the expected volatility of the common stock. Fair value measurements of the convertible note warrant and conversion option derivative liabilities are based on the Black-Derman-Troy model implemented in the Binomial Lattice and Black-Scholes Models, which are considered to be Level 3 fair value measurements. The primary unobservable input utilized in determining the fair value of the convertible note warrant and conversion option derivative liabilities is the expected volatility of the common stock.

Cash and Cash Equivalents

The Company considers all highly liquid investments that are both readily convertible into cash and mature within 90 days from the date of purchase to be cash equivalents.

Accounts Receivable and Allowance for Credit Losses

The Company’s accounts receivables are recorded and stated at the amount expected to be collected determined by each payor, net of an allowance for credit losses, under ASC Topic No. 310, Receivables (“ASC 310”). In accordance with ASC Topic No. 326, Financial Instruments — Credit Losses (“ASC 326”), the Company recognizes credit losses based on a forward-looking current expected credit losses (“CECL”) model. The Company segregates accounts receivables into portfolio segments based on shared risk characteristics, such as line of business and customer type, for evaluation of expected credit losses. The Company makes estimates of expected credit losses based upon its assessment of various factors, including the age of accounts receivable balances, default-based statistics, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The allowance for credit losses is developed using a loss rate method and is recognized in the Condensed Consolidated Statement of Operations. The uncollectible accounts receivables are written off on a quarterly basis in the period when collection activities cease due to a final determination that all or a portion of the balance is no longer collectible and if there is no pending litigation activity related to the receivable. No allowance for credit losses was recorded as of September 30, 2023 and December 31, 2022.

Inventories, net

The Company accounts for inventory under Accounting Standard Codification Topic No. 330, Inventory (“ASC 330”). Inventories consist of intravenous chemotherapy drugs and oral prescription drugs. Inventories are stated at the lower of cost, determined using the weighted average cost method of inventory valuation, or net realizable value. Net realizable value is determined using the selling price, less costs to sell.

The Company receives purchase discounts on products purchased. Contractual arrangements with vendors, including manufacturers and wholesalers, normally provide for the Company to receive purchase discounts from established list prices in one, or a combination, of the following forms: (i) a direct discount at the time of purchase or (ii) a discount for the prompt payment of invoices. Additionally, in other circumstances, the Company may receive rebates when products are purchased indirectly from a manufacturer (e.g., through a wholesaler). These rebates are recognized when intravenous chemotherapy drugs and oral prescription drugs are dispensed and are generally calculated by manufacturers within 30 days after the end of each completed quarter. The Company also receives additional rebates under its wholesaler contracts if it exceeds contractually defined annual purchase volumes. Purchase rebates are recorded as reductions to cost of services.

Goodwill

The Company accounts for goodwill under ASC No. 350, Intangibles - Goodwill and Other (“ASC 350”). Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net assets acquired in our business combinations.

Goodwill is not amortized but is required to be evaluated for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company performs its annual testing of impairment for goodwill in the fourth quarter of each year. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit.

In assessing goodwill for impairment, an entity has the option to assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary. An entity can choose not to perform a qualitative assessment for any of its reporting units and proceed directly to the use of the two-step impairment test.

When assessing goodwill for impairment for the three months ended March 31, 2023, we first performed a qualitative assessment to determine whether it was necessary to perform the two-step quantitative analysis. Based on the qualitative assessment including our share price decrease as well as factors related to macroeconomic conditions, industry and market considerations, cost factors, financial performance and market capitalization, we determined it was likely that our reporting unit fair value was less than its carrying value and the two-step impairment test was performed. Based on the results of our assessment performed there was a goodwill impairment of $16,867 for the three months ended March 31, 2023. There was no impairment of goodwill recorded for the three months ended September 30, 2023. Goodwill impairment recorded for the three and nine months ended September 30, 2023 was $0 and $16,867, respectively.

Debt

The Company accounts for debt net of debt issuance costs and debt discount. Debt issuance costs and debt discount are

Table of Contents

capitalized, netted against the related debt for presentation purposes, and amortized to interest expense over the terms of the related debt using the effective interest method.

The Company accounts for bifurcated, debt-classified embedded features separately as derivative liabilities pursuant to ASC Topic No. 815, Derivatives and Hedging ("ASC 815"). Bifurcated, debt-classified embedded features are recorded at fair value on the Company's balance sheet with subsequent changes in fair value recorded in the Condensed Consolidated Statement of Operations each reporting period.

Investments in Marketable Securities

The Company's investments in marketable securities are classified as available-for-sale and are carried at fair value. The Company accounts for its investment securities available for sale using the fair value election pursuant to ASC 825, Financial Instruments ("ASC 825"), where changes in fair value are recorded in unrealized gains (losses), net on the Company's Condensed Consolidated Statements of Operations. The Company determines the appropriate classification of these investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company’s marketable securities are classified as current assets if the maturity date is less than one year from the balance sheet date.

Interest income and accretion on marketable securities are included in interest income in the Condensed Consolidated Statements of Operations. Realized gains and losses on sales of securities, and other-than-temporary declines in the fair value of marketable securities, if any, are included as a component of other income (expense), net in the Condensed Consolidated Statements of Operations. The cost of securities sold is based on the First In, First Out method.

At each reporting period, the Company evaluates available-for-sale marketable securities, to the extent the fair value option is not elected, for any credit-related impairment when the fair value of the investment is less than its amortized cost. If the Company determines that the decline in fair value is below the carrying value and this decline is other-than-temporary, credit-related impairment is recognized in the Consolidated Statement of Operations in accordance with ASC 320, Debt Securities. As of September 30, 2023, there were no available-for-sale instruments for which the fair value option was not elected.

Emerging Growth Company

Pursuant to the Business Combination, the Company qualifies as an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933 ("Securities Act"), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and has elected to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company, nor an emerging growth company which has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used.

Recently Adopted Accounting Standards

In June 2016, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, instead of when incurred. In November 2018, the FASB issued Accounting Standard Update 2018-19, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2018-19”), which amends Subtopic 326-20 (created by ASU 2016-13) to explicitly state that operating lease receivables are not in the scope of Subtopic 326-20. Additionally, in April 2019, the FASB issued Accounting Standard Update 2019-04, Codification Improvements to Topic 326, Financial Instruments — Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments (“ASU 2019-04”); in May 2019, the FASB issued Accounting Standards Update 2019-05, Financial Instruments — Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”); in November 2019, the FASB issued Accounting Standards Update 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842):

Table of Contents

Effective Dates and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2019-10”), and in March 2022, the FASB issued Accounting Standard Update 2022-02, Financial Instruments — Credit Losses: Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”), to provide further clarifications on certain aspects of ASU 2016-13 and to extend the nonpublic entity effective date of ASU 2016-13. The changes (as amended) are effective for the Company for annual and interim periods in fiscal years beginning after December 15, 2022. An entity may early adopt ASU 2016-13, as amended, for annual and interim periods in fiscal years beginning after December 15, 2018. ASU 2016-13 introduced a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including receivables, contract assets and held-to-maturity debt securities, which requires the Company to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 also expands disclosure requirements.

The Company adopted the ASU 2016-13, as amended, effective January 1, 2023, which resulted in changes to the Company’s accounting policies for accounts receivables. Upon adoption of ASU 2016-13, the Company evaluated accounts receivables on a collective (i.e., portfolio) basis when similar risk characteristics were shared. The adoption of this standard did not have a material impact on our consolidated financial statements and there was no allowance for credit losses recorded as of September 30, 2023.

Recently Issued Accounting Standards

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06"), which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU 2020-06 also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. The new standard is effective for the Company beginning January 1, 2024. The Company is currently evaluating the effect of ASU 2020-06 on the Company’s consolidated financial statements and related disclosures.

In October 2021, the FASB issued ASU 2021-08, Business Combinations: Accounting for Contract Assets and Contract Liabilities from Contracts with Customers ("ASU 2021-08"). Under ASU 2021-08, an acquirer must recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contract with Customers (“ASC 606”). The guidance is effective for interim and annual periods beginning after December 15, 2023, with early adoption permitted. The Company will adopt ASU 2021-08 on January 1, 2024 on a prospective basis. The Company does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements and related disclosures.

Note 3. Significant Risks and Uncertainties Including Business and Credit Concentrations

Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, accounts receivable, and investment securities.

Cash accounts in a financial institution may, at times, exceed the Federal Deposit Insurance Corporation coverage of $250 per account ownership category. The Company has not experienced losses on these accounts, and management believes the Company is not exposed to significant risks on such accounts.

The Company’s accounts receivable has implicit collection risk. The Company grants credit without collateral to their patients, most of whom are local residents and are insured under third-party payor agreements. The Company believes this risk is partially mitigated by the Company’s establishment of long-term agreements and relationships with third-party payors that provide the Company with insight into historic collectability and improve the collections process.

The Company's investment securities portfolio is managed by a third party vendor to provide a relatively stable source of investment income from excess liquidity while satisfactorily managing risk, including credit risk, reinvestment risk, liquidity risk, and interest rate risk.

Revenue Concentration Risk

The concentration of net revenue on a percentage basis for major payors for the three and nine months ended September 30, 2023 and 2022 are as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Percentage of Patient Services Net Revenue:
Payor A	11	%	12	%	11	%	14	%
Payor B	14	%	15	%	14	%	16	%

The concentration of gross receivables on a percentage basis for major payors at September 30, 2023 and December 31, 2022 are as follows:

	September 30, 2023		December 31, 2022
Percentage of Gross Receivables of Patient Revenue:
Payor B	10	%	13	%
Payor C	8	%	10	%

All of the Company’s revenue is generated from customers located in the United States.

Vendor Concentration Risk

The concentration of cost of sales on a percentage basis for major vendors for the three and nine months ended September 30, 2023 and 2022 are as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Percentage of Cost of Sales:
Vendor A	100	%	97	%	100	%	69%
Vendor B	N/A		N/A		N/A		29%

Note 4. Accounts Receivable

The Company’s accounts receivable consists primarily of amounts due from third-party payors and patients. See Note 2 for a summary of the Company’s policies relating to accounts receivable and allowance for credit losses.

Accounts Receivable as of September 30, 2023 and December 31, 2022 consist of the following:

(in thousands)	September 30, 2023		December 31, 2022
Oral drug accounts receivable	$	3,238	$	4,165
Capitated accounts receivable	3,187		1,623
FFS accounts receivable	32,388		26,313
Clinical trials accounts receivable	2,488		2,443

Total	$	48,442	$	39,816

The Company adopted ASU 2016-13, as amended, effective January 1, 2023, and determined no allowance for credit losses was required as of September 30, 2023. No allowance for credit losses was recorded as of September 30, 2023.

During the three and nine months ended September 30, 2023, credit losses related to direct write-offs totaled $31 and $42, respectively. Credit losses were a result of accounts receivable on completed contracts that were deemed uncollectible during the period due to delayed collection efforts. During the three and nine months ended September 30, 2023, the Company had recoveries of credit losses of $0 and $11, respectively. During the three and nine months ended September 30, 2022, the Company had net reversals of bad debt recoveries of $28 and $110, respectively and bad debt expense of $115, and $292, respectively.

Note 5. Revenue

The Company recognizes revenue in accordance with ASC 606 on the basis of its satisfaction of outstanding performance obligations. The Company typically fulfills its performance obligations over time, either over the course of a single treatment (fee-for-service or "FFS"), a month (capitation), or a number of months (clinical research). The Company also has revenue that is satisfied at a point in time (dispensary). See Note 2 for summary of the Company’s policies and significant assumptions related to revenue recognition.

Disaggregation of Revenue

The Company categorizes revenue based on various factors such as the nature of contracts, payors, order to billing arrangements, and cash flows received by the Company, as follows:

(in thousands)	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Patient services
Capitated revenue	$	18,056	$	16,355	$	51,410	$	44,815
FFS revenue	35,578		28,272		105,923		73,978
Subtotal	53,634		44,627		157,333		118,793
Dispensary revenue	26,792		18,839		76,228		57,736
Clinical research trials and other revenue	1,609		1,511		4,890		4,530
Total	$	82,035	$	64,977	$	238,451	$	181,059

Refer to Note 20 for Segment Reporting for disaggregation of revenue by reporting segment.

Contract Asset and Liabilities

Under ASC 606, contract assets represent rights to payment for performance contingent on something other than the passage of time and accounts receivable are rights to payment for performance without contingencies. The Company does not have any contract assets as of September 30, 2023 and December 31, 2022. Refer to Note 4 for accounts receivable as of September 30, 2023 and December 31, 2022.

Table of Contents

Contract liabilities represent cash that has been received for contracts, but for which performance is still unsatisfied. As of September 30, 2023 and December 31, 2022, contract liabilities amounted to $545 and $1,139, respectively. Contract liabilities are included within other current liabilities and presented in Note 9 along with refund liabilities due to materiality.

Remaining Unsatisfied Performance Obligations

The accounting terms for the Company’s patient services and dispensary contracts do not extend past a year in duration. Additionally, the Company applies the ‘as invoiced’ practical expedient to its clinical research contracts.

Note 6. Inventories

The Company purchases intravenous chemotherapy drugs and oral prescription drugs from various suppliers. See Note 2 for a summary of the Company’s policies relating to intravenous chemotherapy and oral prescription drugs inventory.

The Company’s inventories as of September 30, 2023 and December 31, 2022 were as follows:

Total	$	12,174	9,261

Note 7. Marketable Securities and Fair Value Measurements

Marketable Securities

The Company accounts for its investment securities as available for sale using the fair value election pursuant to ASC 825, where changes in fair value are recorded in Other, net non-operating income (expense) on the Company's Condensed Consolidated Statements of Operations. The Company’s investments in marketable securities at September 30, 2023 and December 31, 2022 is as follows:

Total available for sale securities	$	72,892	$	47,831	$	—	$	120,723

The Company recorded a net unrealized loss of $157 and a net unrealized loss of $44 for the three and nine months ended September 30, 2023. At September 30, 2023, six securities were in an unrealized loss position. The decline in fair value of our securities since acquisition was attributable to a combination of changes in interest rates and general volatility in the credit market conditions in response to the economic uncertainty caused by the risk of an upcoming recession and monetary policy. The Company does not currently intend to sell any of the securities in an unrealized loss position and further believe, it is more likely than not, that we will not be required to sell these securities before their anticipated recovery.

Accrued interest receivable on cash equivalents and marketable securities was $270 and $274, respectively, at September 30, 2023 and December 31, 2022, and is included within other receivables in the Condensed Consolidated Balance Sheets.

Fair Value Measurements

The following table presents the carrying amounts of the Company’s recurring and non-recurring fair value measurements at September 30, 2023 and December 31, 2022:

	September 30, 2023
(in thousands)	Total		Level 1		Level 2		Level 3
Financial assets:
Marketable securities	$	59,877	$	—	$	59,877	$	—
Financial liabilities:
Derivative warrant liabilities	$	292	$	—	$	292	$	—
Earnout liabilities	11		—		—		11

Contingent consideration liability	1,813		—		1,813		—
Non-recurring fair value measurement:
Goodwill	$	7,230	$	—	$	—	$	7,230

As of September 30, 2023, derivative warrant liabilities of $292 were transferred from a Level 3 to a Level 2 financial instrument as a result of the valuation being based on the market price of our public warrants, which management considers to be a similar and comparable instrument, as compared to the previous valuation which was based on the Binomial Lattice Model.

Non-recurring fair value measurement:
Goodwill	$	21,418	$	—	$	—	$	21,418

The carrying amounts of cash, accounts receivable, other receivables, and accounts payable approximate fair value because of the short maturity and high liquidity of these instruments.

The Company measures its investments (including cash equivalents, marketable securities, and non-current investments) at fair value on a recurring basis and classifies those instruments within Level 2 of the fair value hierarchy. Investment securities, including U.S. Treasury Bills purchased in the secondary market and U.S. Treasury bonds, are classified within Level 2 of the fair value hierarchy because pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined using models or other valuation methodologies.

The Company measures its private derivative warrants at fair value on a recurring basis and classifies those instruments within Level 2 of the fair value hierarchy because the valuation is based on an observable input of a similar instrument. The Company measures its earnout, convertible note warrant derivative liability, optional redemption derivative liability, conversion option derivative liability, and contingent consideration liability on a recurring basis and classifies those instruments within Level 3 of the fair value hierarchy because unobservable inputs are used to measure fair value. See Note 2 for a summary of the Company’s policies relating to fair value measurements, and Note 11 for more detail on the convertible note warrant, optional redemption, and conversion option derivative liabilities.

The Company measures goodwill at fair value on a nonrecurring basis and classifies goodwill within Level 3 of the fair value hierarchy. It was concluded in connection with the preparation of these financial statements that, based on the results of our most recent qualitative assessment performed for the three months ended September 30, 2023, there was no impairment of goodwill recorded for the three months ended September 30, 2023.

The following table presents information about the Company’s financial liabilities that are measured at fair value on a recurring basis at September 30, 2023:

(in thousands)	Earnout Liability		Conversion Option Derivative Liability
Balance at December 31, 2021	$	60,018	$	—
Conversion option derivative liability acquired (see Note 11 for detail)	—		28,160

Table of Contents

considered to be a Level 2 fair value measurement, and the contingent consideration liability was valued using a present value factor, which is considered to be a Level 2 fair value measurement. As of December 31, 2022, derivative warrant and earnout liabilities were valued using a Binomial Lattice and Monte-Carlo Simulation Model, respectively, which are considered to be Level 3 fair value measurements.

As of September 30, 2023 and December 31, 2022, the convertible note warrant and conversion option derivative liabilities were valued using the Binomial Lattice and Black-Scholes Models, which are considered to be Level 3 fair value measurements. The primary unobservable input utilized in determining the fair value of our Level 3 liabilities is the expected volatility of the common stock. A summary of the inputs used in the valuations is as follows:

	September 30, 2023

On August 9, 2022, the Company issued a senior secured convertible note that contains embedded warrant, optional redemption, and conversion option features. Due to the economic disincentive to redeem and the make whole amount that would be required to be paid, it is highly unlikely that the optional redemption would occur, reducing the value during the period to a qualitatively immaterial amount. See Note 11 for additional detail. A summary of the inputs used in the initial measurement of the convertible note warrant and conversion option derivative liabilities is as follows:

	August 9, 2022
	(Initial Measurement)
	Convertible Note Warrant Derivative Liability			Conversion Option Derivative Liability
Unit price	$	6.63		$	6.63

Uncertainty of Fair Value Measurement from Use of Significant Unobservable Inputs

The inputs to estimate the fair value of the Company’s earnout, convertible note warrant, and conversion option derivative liabilities were the market price of the Company’s common stock, their remaining expected term, the volatility of the

23

Table of Contents

Company’s common stock price and the risk-free interest rate over the expected term. Significant changes in any of those inputs in isolation can result in a significant change in the fair value measurement.

Generally, an increase in the market price of the Company’s shares of common stock, an increase in the volatility of the Company’s shares of common stock, and an increase in the remaining term of the derivative liabilities would each result in a directionally similar change in the estimated fair value of the Company’s derivative liabilities. Such changes would increase the associated liability while decreases in these assumptions would decrease the associated liability. An increase in the risk-free interest rate would result in a decrease in the estimated fair value measurement and thus a decrease in the associated liability. The Company has not, and does not plan to, declare dividends on its common stock and, as such, there is no change in the estimated fair value of the derivative warrant liabilities due to the dividend assumption.

Note 8. Property and Equipment, Net

The Company accounts for property and equipment at historical cost less accumulated depreciation. See Note 2 for a summary of the Company’s policies relating to property and equipment.

Note 10. Leases

The Company leases clinics, office buildings, and certain equipment under noncancellable financing and operating lease agreements that expire at various dates through November 2031. See Note 2 for a summary of the Company’s policies relating to leases.

The initial terms of operating leases range from 1 to 10 years and certain leases provide for free rent periods, periodic rent increases, and renewal options. Monthly payments for these leases range from $0 to $60. All lease agreements generally require the Company to pay maintenance, repairs, property taxes, and insurance costs, which are generally variable amounts based on actual costs incurred during each applicable period.

The Company has determined that periods covered by options to extend the Company's leases are excluded from the lease terms as it is not reasonably certain the Company will exercise such options.

Lease Modifications

During the three months ended September 30, 2023, the Company extended the lease terms of three clinics in California. The extensions constitute a lease modification that qualifies as a change of accounting for the original lease and not a separate contract. Accordingly, for the three months ended September 30, 2023, the Company recognized the difference of $1,274 as an increase to the operating lease liability; net of lease incentives of $1,274, as an increase to operating lease right-of-use asset.

During the nine months ended September 30, 2023, the Company expanded its lease space for one clinic in California and extended the lease terms of five clinics in California. The expansion and extension constitute a lease modification that qualifies as a change of accounting for the original lease and not a separate contract. Accordingly, for the nine months ended September 30, 2023, the Company recognized the difference of $3,018 as an increase to the operating lease liability; net of lease incentives of $3,021, as an increase to operating lease right-of-use asset, and $3 as an increase to rent expense.

Note 11. Debt

Senior Secured Convertible Note

On August 9, 2022, TOI entered into a Facility Agreement (the “Facility Agreement”) with certain lenders (“Lenders”) and Deerfield Partners L.P. (“Agent”), pursuant to which, TOI borrowed cash loans from the Lenders in the amount of $110,000, in exchange for which, TOI issued to each Lender a secured convertible promissory note (“Senior Secured Convertible Note”), which is payable to such Lenders in an amount equal to the unpaid principal amount of loans held by such Lender.

The Senior Secured Convertible Note will mature on August 9, 2027 (the “Maturity Date”) and shall bear interest at the rate of 4.00% per annum from August 9, 2022, on the outstanding principal amount, any overdue interest and any other amounts and obligations. The interest shall be paid in cash quarterly in arrears commencing on October 1, 2022. In case of any prepayment, repayment or redemption of the Senior Secured Convertible Note, the Company shall pay any accrued and unpaid interest on the principal, along with a make whole amount and an exit fee.

26

Table of Contents

The Facility Agreement requires the Company to meet certain operational and reporting requirements, including, but not limited to, customary regulatory, financial reporting, and disclosure requirements. Additionally, limitations are placed on the Company's ability to merge with other companies and enter into other debt arrangements and permitted investments are limited to amounts specified in the Facility Agreement. The Facility Agreement also provides certain restrictions on dividend payments and other equity transactions and requires the Company to make prepayments under specified circumstances. Financial covenants in the Facility Agreement require the Company to maintain a minimum unrestricted cash and cash equivalent balance of $40,000 and minimum net quarterly revenues of $50,000 during fiscal year 2023; $75,000 during fiscal year 2024; and $100,000 during fiscal year 2025. Cash Equivalents as defined by the Facility Agreement means (a) any readily-marketable securities (i) issued by, or directly, unconditionally and fully guaranteed or insured by the United States federal government or (ii) issued by any agency of the United States federal government the obligations of which are fully backed by the full faith and credit of the United States federal government, (b) any readily-marketable direct obligations issued by any other agency of the United States federal government, any state of the United States or any political subdivision of any such state or any public instrumentality thereof, in each case having a rating of at least “A-1” from S&P or at least “P-1” from Moody’s, (c) any commercial paper rated at least “A-1” by S&P or “P-1” by Moody’s and issued by any person organized under the laws of any state of the United States, (d) any United States dollar-denominated time deposit, insured certificate of deposit, overnight bank deposit or bankers’ acceptance issued or accepted by any commercial bank that (A) is organized under the laws of the United States, any state thereof or the District of Columbia, (B) is “adequately capitalized” (as defined in the regulations of its primary federal banking regulators) and (C) has Tier 1 capital (as defined in such regulations) in excess of $250,000 and (e) shares of any United States money market fund that (i) has substantially all of its assets invested continuously in the types of investments referred to in clause (a), (b), (c) and/or (d) above with maturities as set forth in the proviso below, (ii) has net assets in excess of $500,000 and (iii) has obtained from either S&P or Moody’s the highest rating obtainable for money market funds in the United States; provided, however, that the maturities of all obligations specified in any of clause (a), (b), (c) and (d) above shall not exceed one year. Additionally, the registration rights agreement between the Company and certain stockholders of Legacy TOI and DFPH entered into in connection with the Business Combination requires the Company to have an effective registration statement and calls for payment should the registration statement cease to remain effective. The Company was in compliance with the covenants of the Facility Agreement as of September 30, 2023.

Conversion Options

The Senior Secured Convertible Note contains several embedded conversion options (the “Conversion Options”) that grant the holders of the Senior Secured Convertible Note the ability to convert the Senior Secured Convertible Note at any time on or after date of issuance of the note. The Conversion Options are convertible into shares of the Company’s common stock (such converted shares, “Conversion Shares”) and, in certain circumstances, a combination of cash and shares of the Company’s common stock, or a combination of cash, other assets and securities or other property of any Company successor entity. The Conversion Shares or settlement amounts shall be computed on the basis of a predefined formula, with a set conversion price of $8.567 as one of the inputs and a conversion cap of 14,663,019 shares. The if-converted value did not exceed the principal amount as of September 30, 2023. No Conversion Shares were issued as of September 30, 2023 and December 31, 2022.

The Company evaluated the Conversion Options of the Senior Secured Convertible Note under ASC 815 and concluded that they require bifurcation from the host contract as a separate unit of account. The Conversion Options do not meet the criteria to be classified in shareholders’ equity and hence, are accounted for as a derivative liability remeasured at fair value at each balance sheet date with changes in fair value reported in earnings.

The Conversion Options contain certain limits on exercise if, after giving effect to the exercise, the Lender would beneficially own a number of shares of common stock of the Company in excess of those permissible under the terms of the Senior Secured Convertible Note. The number of shares to be issued against these notes and conversion price are each subject to adjustments provided under the terms of Senior Secured Convertible Note.

The holder shall receive dividends on the Senior Secured Convertible Note and distributions of any kind made to the holders of common stock, other than dividends of, or distributions in, shares, to the same extent as if the holder had converted the Senior Secured Convertible Note into such shares and had held such shares on the record date for such dividends and distributions any limitations on conversion options.

Optional Redemption

The Facility Agreement also provides the Company the right to redeem the outstanding principal amount of each note (“Optional Redemption”) for the Optional Redemption Price. The Company shall not affect any Optional Redemption under this Senior Secured Convertible Note unless along with this, the Company effects an optional redemption under all other notes in accordance with the terms thereof, on a pro rata basis, based upon the respective applicable original principal amount of each of the notes outstanding as of the date the notice for Optional Redemption is delivered to the holders.

27

Table of Contents

The Company evaluated the Optional Redemption feature of the Senior Secured Convertible Note under ASC 815 and concluded that it requires bifurcation from the host contract as a separate unit of account. The Optional Redemption feature does not meet the criteria to be classified in shareholders’ equity and hence, is accounted for as a derivative liability remeasured at fair value at each balance sheet date with changes in fair value reported in earnings. The fair value of the Optional Redemption feature is de minimis.

If the principal redemption amount specified in an Optional Redemption notice is less than the entire principal amount then outstanding, the principal amount specified in each conversion notice shall be applied (i) first, to reduce, on a dollar-for-dollar basis, the principal amount of the note in excess of the principal redemption amount until such excess principal amount is reduced to zero and (ii) to reduce, on a dollar-for-dollar basis, the principal redemption amount until all of such principal redemption amount shall have been converted.

Convertible Note Warrants

The Facility Agreement also provides for the issuance of warrants (the “Convertible Note Warrants”) on each date any principal amount of any Senior Secured Convertible Note is paid, repaid, redeemed, or prepaid at any time prior to the Maturity Date. Convertible Note Warrants are exercisable from their original issue date to August 9, 2027, for purchase of an aggregate amount of Conversion Shares into which such principal amount of Senior Secured Convertible Note was convertible into, immediately prior to such payment, at an exercise price of $8.567. The holder of Convertible Note Warrants may pay the exercise price in cash or exercise the warrant on cashless basis or through a reduction of an amount of principal outstanding under any Senior Secured Convertible Note held by such holder. In the event that the Convertible Note Warrant has not been exercised in full as of the last business day during its term, the holder shall be deemed to have exercised the purchase rights represented by the Convertible Note Warrant in full as a cashless exercise, in which event the Company shall issue number of shares to the holder computed on the basis of a predefined formula.

The Company evaluated the Convertible Note Warrants of the Senior Secured Convertible Note under ASC 815 and concluded that they require bifurcation from the host contract as a separate unit of account. The Convertible Note Warrants do not meet the criteria to be classified in shareholders’ equity and hence, are accounted for as a derivative liability remeasured at fair value at each balance sheet date with changes in fair value reported in earnings.

The Convertible Note Warrant holder shall be entitled to receive any dividend or distribution made by the Company to the holders of common stock to the same extent as if the holder had exercised the Convertible Note Warrants in full in a cash exercise.

The number of shares to be issued against these warrants and exercise price are each subject to adjustments provided under the terms of Convertible Note Warrants. The Convertible Note Warrants contain certain limits on exercise if, after giving effect to the exercise, the Lender would beneficially own a number of shares of common stock of the Company in excess of those permissible under the terms of the Convertible Note Warrants. Further, the Convertible Note Warrants can be fully or partially settled in cash in certain cases in accordance with the terms of issuance such as when shares issuable upon exercise of the warrants exceed a predefined number, upon occurrence of predefined event of default and upon occurrence of predefined events that will bring a fundamental change in the Company such as merger, consolidation, business combination, recapitalization, reorganization, reclassification or other similar event.

As of September 30, 2023 and December 31, 2022, there were no Convertible Note Warrants outstanding.

Allocation of Proceeds

The Company has allocated total issuance proceeds of $110,000 among the Senior Secured Convertible Note and Convertible Note Warrants based on fair value. Upon issuance of the Convertible Note Warrants, the Company recorded Convertible Note Warrants, Optional Redemption, and Conversion Options of $0, $0 and $28,160, which were recorded as a debt discount to the Senior Secured Convertible Note of $110,000. The Company will amortize the debt discount over a period of 5 years (of which 3.86 years remain).

The total issuance costs of $4,924 was allocated among the Senior Secured Convertible Note, Convertible Note Warrants, Optional Redemption, and Conversion Options, by allocating costs of $0, $0, and $1,261 to the Convertible Note Warrants, Optional Redemption, and Conversion Options with the residual cost of $3,663 being allocated to the Senior Secured Convertible Note (in addition to the debt discount). The Company expensed issuance costs allocated to Warrants, Optional Redemption, and Conversion Options at inception and will amortize the costs allocated to the Senior Secured Convertible Note over a period of 5 years (of which 3.86 years remain).

Amounts Outstanding and Recognized during the Periods Presented

The Senior Secured Convertible Note as of September 30, 2023 and December 31, 2022 consists of the following:

(in thousands)	September 30, 2023		December 31, 2022
Senior Secured Convertible Note, due August 9, 2027	$	110,000	$	110,000

Less: Unamortized debt discount	21,718		25,925
Long-term debt, net of unamortized debt discount and issuance costs	$	85,254	$	80,621

The amortization of the debt issuance costs and debt discount was charged to interest expense for all periods presented. For the three months ended September 30, 2023, the effective yield was 13.38%. The amount of debt issuance costs and debt discount included in interest expense for the three and nine months ended September 30, 2023 was $1,566 and $4,633, respectively. The Company recorded interest of $1,125 and $3,337 on the Credit Agreement term loan for the three and nine months ended September 30, 2023, respectively. There was $892 of debt issuance cost and debt discount amortization included in interest expense, $648 of recorded interest related to this facility for the three and nine months ended September 30, 2022.

On August 9, 2022, the Company also entered into the Guarantee and Security Agreement (“Guarantee Agreement”) with the Agent for the purpose of providing a guarantee of all the obligations under the Facility Agreement (refer to Note 15. Commitments and Contingencies for detail).

Note 12. Income Taxes

The Company recorded income tax expense of $135 and $278 for the three and nine months ended September 30, 2023, respectively, as compared to income tax benefit of $24 and income tax expense of $124 for the three and nine months ended September 30, 2022, respectively. The increase of $159, in income tax expense for the three months ended September 30, 2023 as compared to the three months ended September 30, 2022, is primarily related to the corresponding increase in the valuation allowance for TOI. The Company's effective tax rate decreased to (0.43)% for the nine months ended September 30, 2023, from 1.10% for the nine months ended September 30, 2022.

The Company's effective tax rate for the nine months ended September 30, 2023, was different than the U.S. federal statutory tax rate of 21.00%, primarily due to the increased valuation allowance, partially offset by the tax effect of the change in fair market value of the warrant, earn out, and derivative liabilities, as well as the Section 162(m) limitation on compensation for covered employees and Section 163(l) limitation on interest expense related to the convertible note, which are non-deductible for federal income tax purposes.

Each share of preferred stock is convertible, at any time on the part of the holder except with respect to the Beneficial Ownership Limitation (defined below), into 100 shares of common stock.

Blocker/Beneficial Ownership Limitation

The preferred stock is subject to a beneficial ownership limitation such that the preferred stock may not, at any time, be convertible into more than 4.99% of the total number of shares of common stock outstanding (“Beneficial Ownership Limitation”).

Voting

The holders of preferred stock do not have voting rights in the Company.

Dividends

The holders of preferred stock are entitled to receive dividends whenever funds are legally available and when declared by the board of directors on an as-converted basis. No dividends have been declared as of September 30, 2023.

Assumed Public Warrants and Private Placement Warrants

As a result of the Business Combination, holders of the public warrants and private placement warrants are entitled to acquire common stock of the Company. The warrants became exercisable 30 days from the completion of the Business Combination, on December 12, 2021, and will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation. As of September 30, 2023, there are 5,749,986 public warrants outstanding and 3,177,542 private placement warrants outstanding. None of the public and private warrants holders have exercised since the Business Combination.

Each warrant entitles the holder to purchase one share of common stock for $11.50 per share. Private warrants held by the initial purchaser or certain permitted transferees may be exercised on a cashless basis.

If the reported last sale price of the common stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders, the Company may redeem all the public warrants at a price of $0.01 per warrant upon not less than 30 days’ prior written notice.

If the Company calls the public warrants for redemption, management will have the option to require all holders that wish to exercise the public warrants to do so on a cashless basis. The Company will not be required to net cash settle the warrants.

The private warrants are exercisable on a cashless basis and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the private warrants are held by someone other than the initial purchasers of their

permitted transferees, the private warrants will be redeemable by the Company and exercisable by such holders on the same basis as the public warrants.

Share Repurchase Program

On August 28, 2023, the Company's Board approved a share repurchase program with authorization to purchase up to 2 million shares of the Company’s common stock. During the three months ended September 30, 2023, the Company repurchased 140,646 shares of its common stock for $125 through one or more securities broker-dealers, in open market purchases and negotiated market purchases. The financial impact of the share buybacks, including the change in the number of outstanding shares and its effect on earnings per share (EPS), is disclosed in the earnings per share computation in accordance with ASC 260, Earnings Per Share.

On June 14, 2023, the Company's Board approved a share repurchase program with authorization to purchase up to 5 million shares of the Company's stock. During the three months ended June 30, 2023, the Company repurchased 1,593,128 shares of its common stock for $894 through one or more securities broker-dealers, in open market purchases and negotiated market purchases.

On May 10, 2022, the Company's Board consented to the adoption and approval of the Share Repurchase Program, authorizing up to $20,000 to be spent on the repurchase of the Company's common stock, expiring on December 31, 2022. The Company repurchased and immediately retired 1,500,000 shares of its common stock for $9,000 from a related party during the year ended December 31, 2022, before the expiration of the program.

Note 14. Share-Based Compensation

Non-Qualified Stock Option Plan

On January 2, 2019, the Company issued and adopted the 2019 Non-Qualified Stock Option Plan (the “2019 Plan”) to incentivize directors, consultants, advisors, and other key employees of the Company and its subsidiaries to continue their association by providing opportunities to participate in the ownership and further growth of the Company. The 2019 Plan provides for the grant of options (the “Stock Options”) to acquire common shares of the Company.

Stock Options are exercised from the pool of shares designated by the appropriate Committee of the Board of Directors. The grant-date fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The grant date fair value of the service vesting and the performance vesting options is recognized as an expense over the requisite service period and upon the achievement of the performance condition deemed probable of being achieved, respectively. The exercise price of each Stock Option shall be determined by the Committee and may not be less than the fair market value of the common shares on the date of grant. Stock Options have 10-year terms, after which they expire and are no longer exercisable.

The total number of common shares for which Stock Options may be granted under the 2019 Plan shall not exceed 13,640. The 2019 Plan was amended on November 6, 2020, pursuant to which the total number of common shares for which Stock Options may be granted under the 2019 Plan shall not exceed 15,640.

Stock Options become vested upon fulfillment of either service vesting conditions, performance vesting conditions, or both, as determined by the award agreement entered into by the Company and optionee. The service vesting requirement states that: (i) 25% of the service vesting options shall vest on the first anniversary of the grant date and (ii) the remaining 75% shall vest on an equal monthly-basis, so long as the optionee has remained continuously employed by the Company from the date of the award through the fourth anniversary of the grant date. The performance vesting requirement states that Stock Options shall vest upon sale of the Company only if the optionee has been continuously employed by the Company or its subsidiaries from the grant date through the date of such sale of the Company. For the awards vesting based on service conditions only and that have a graded vesting schedule, the Company recognizes compensation expense for vested awards in earnings, net of actual forfeitures in the period they occur, on a straight-line basis over the requisite service period.

Conversion of the Stock Options

In conjunction with the Business Combination, the Company amended and fully restated the 2019 Plan through the establishment of the 2021 Incentive Plan (“2021 Plan”). Pursuant to the 2021 Plan, each remaining legacy Stock Option from the 2019 Plan that was outstanding immediately prior to the Business Combination, whether vested or unvested, was converted into an option to purchase a number of shares of common stock (each such option, an “Exchanged Option”) equal to the product (rounded down to the nearest whole number) of (i) the number of shares of Legacy TOI stockholders subject to such Stock Option immediately prior to the Business Combination, and (ii) an exercise price per share equal to (A) the exercise price per

31

Table of Contents

share of such Stock Option immediately prior to the consummation of the Business Combination, divided by (B) the Common Stock Exchange Ratio ("Stock Option Exchange Ratio"). Following the Business Combination, each Exchanged Option that was previously subject to time vesting only, will continue to be governed by the same terms and conditions (including vesting and exercisability terms) as were applicable to the corresponding former old Stock Option immediately prior to the consummation of the Business Combination. Each Exchanged Option that was previously subject to performance vesting, will no longer be subject to the sale of the Company, and was modified to include service requirements only, under which, the Exchange Options will vest on a monthly-basis, so long as the optionee has remained continuously employed by the Company from the date of the Business Combination through the third anniversary of the Closing Date. The Company treated the Exchanged Options that were previously subject to performance conditions as a new award granted at the Closing Date. The Exchanged Options that were previously subject to service vesting only were not modified as a result of the Business Combination. All stock option activity was retroactively restated to reflect the Exchanged Options.

As of the Closing Date, the 11,850 Stock Options outstanding under the 2019 Plan were converted into 6,925,219 Exchanged Options after effect of the Common Stock Exchange Ratio. This effect of the Common Stock Exchange Ratio has been retroactively adjusted throughout the Company's condensed consolidated financial statements.

As of September 30, 2023, the total number of shares of common stock remaining available for future awards (e.g., non-qualified stock options, incentive stock options, restricted stock units, restricted stock awards) under the 2021 Plan is 6,782,851.

The weighted average assumptions used in the Black-Scholes-Merton option-pricing model for the units granted during the nine months ended September 30, 2023 and 2022 Stock Options are provided in the following table:

	September 30, 2023	September 30, 2022
Valuation assumptions:
Expected dividend yield	—%	—%
Expected volatility	64.00%	35.0% to 45.0%
Risk-free rate	3.40%	2.33% to 2.84%
Expected term (years)	6.25	6.07 to 6.65

The Company used the simplified method to calculate the expected term of stock option grants because sufficient historical exercise data was not available to provide a reasonable basis for the expected term. Under the simplified method, the expected term is estimated to be the mid-point between the vesting date and the contractual term of the option.

Stock option activity during the nine months ended September 30, 2023 and 2022 is as follows:

Stock options	Number of shares	Weighted average exercise price		Weighted average remaining contractual term	Aggregate intrinsic value (in thousands)
Balance at January 1, 2023	8,049,474	$	2.14

Total share-based compensation expense relating to stock options during the three and nine months ended September 30, 2023 was $2,563 and $7,823, respectively. Total share-based compensation expense relating to stock options during the three and nine months ended September 30, 2022 was $2,756 and $8,837, respectively.

At September 30, 2023, there was $13,279 of total unrecognized compensation cost related to unvested service Stock Options granted under the 2021 Plan and 2019 Plan that are expected to vest. That cost is expected to be recognized over a weighted average period of 2.56 years as of September 30, 2023. The total fair value of common shares vested during the nine months ended September 30, 2023 and 2022 was $1,616 and $6,976, respectively.

Restricted Stock Awards (“RSAs”) and Restricted Stock Units (“RSUs”)

Agajanian Holdings (“Holdings”), a holder of Series A Preferred Shares of Legacy TOI, entered into arrangements with physicians employed by the TOI PCs to issue RSAs which represent Series A Preferred Shares of Legacy TOI. The Legacy TOI RSAs only have performance vesting requirements linked to the sale of the Company so long as the grantee remains continuously and actively employed by the Company’s subsidiaries through the vesting date.

Conversion of the RSAs

Each of the Legacy TOI RSAs, from the Plan that was outstanding immediately prior to the Business Combination, whether vested or unvested, was converted into an RSU equal to the product (rounded down to the nearest whole number) of (i) the number of shares of RSAs immediately prior to the Business Combination, (ii) conversion rate of 1:10 of the Series A Preferred Shares of Legacy TOI, and (iii) the Common Stock Exchange Ratio. Following the Business Combination, each RSU is no longer subject to the sale of the Company event in order to vest, but was modified to include service requirements only. The service vesting requirement states that: (i) 16.67% of the RSUs shall vest on the sixth month anniversary of the Closing Date, and (ii) the remaining 83.33% shall vest on an equal quarterly-basis, so long as the grantee has remained continuously employed by the Company from the date of the award through the third anniversary of the grant date. The Company treated the RSUs that were previously subject to performance conditions as a new award granted at the Closing Date. All RSAs activity was retroactively restated to reflect the RSUs.

As of the Closing Date, the 2,210 RSAs outstanding under the Plan were converted into 1,291,492 RSUs upon the completion of the Business Combination after giving effect to the Common Stock Exchange Ratio. This effect of the Common Stock Exchange Ratio has been retroactively adjusted throughout our condensed consolidated financial statements.

The weighted-average grant date fair values of the RSUs granted during nine months ended September 30, 2023 and 2022, were determined to be $0.64 and $6.82, respectively, based on the fair value of the Company’s common share at the grant date.

A summary of the activity for the RSUs for the nine months ended September 30, 2023 and 2022, respectively, are shown in the following table:

	Nine Months Ended September 30,

Unvested at end of year	2,124,905	$	4.44	2,170,047	$	10.98

The total share-based compensation expense related to RSUs during the three and nine months ended September 30, 2023 was $1,188 and $4,715, respectively and during the three and nine months ended September 30 , 2022 was $2,356 and $5,848, respectively.

As of September 30, 2023 there was $9,033 of unrecognized compensation expense related to the RSUs that are expected to vest. That cost is expected to be recognized over a weighted average period of 2.56 years as of September 30, 2023. As of September 30, 2023, 2,024,351 of the RSUs have vested and zero were net settled to cover the required withholding tax upon vesting.

RSUs granted to Medical Employees and Nonemployees

In 2022, the Company entered into arrangements with certain medical directors and supervisors of advanced practice providers employed by or engaged as independent contractors of TOI to issue RSUs of the Company (“Medical RSUs”). Vesting on each annual Medical RSU award is dependent on the participant performing a specified minimum number of service hours during the calendar year (“One-Year Term”) and further contingent upon the participant’s continued service to, or employment by, the Company through the grant date. The Company’s regular grant date for these Medical RSU awards is in the first quarter of the calendar year following the one-Year Term.

The number of Medical RSUs granted to each such participant is determined by dividing a fixed monetary value by the trailing five-day closing price per share of the Common Stock preceding the grant date. Due to the calculation, some Medical RSU awards are liability-classified whereas other Medical RSU awards have a fixed number of shares and are equity-classified.

In the fourth quarter of 2022, the Company amended the terms of Medical RSUs previously issued to approximately 21 participants during the first quarter of 2022. The amendment primarily updated the vesting period and conditions. The original terms of the Medical RSU awards were deemed improbable of vesting at the modification date whereas the amended Medical RSU awards were deemed probable of vesting at the modification date, and thus are a Type III modification under ASC 718. The modification to the Medical RSUs resulted in $187 incremental share-based compensation expense before forfeitures, $(11) after accounting for forfeitures related to participants who did not perform the minimum number of service hours specified, recorded in the Company's Statement of Operations.

The total fair value of the liability-classified Medical RSU awards granted in 2022 and outstanding as of December 31, 2022 was approximately $264, which represents the fixed monetary value of the awards. The weighted-average grant-date fair value, based on the Company’s share price granted during 2023 and 2022 was $1.00 and $3.56 for equity-classified Medical RSUs granted. There were no unvested equity-classified Medical RSU awards outstanding as of September 30, 2023.

A summary of the activity for the equity-classified Medical RSUs for the nine months ended September 30, 2023 is shown in the following table:

Total compensation costs for Medical RSUs was $814 and $872 for the three and nine months ended September 30, 2023. As of September 30, 2023, all Medical RSUs have vested.

Earnout Shares granted to Employees

As part of the Business Combination, DFPH issued to eligible Legacy TOI stockholders and Legacy TOI employees the contingent right to receive up to $12.5 million additional shares of common stock (“Legacy TOI Earnout Shares”), in two tranches of $5.0 million ("First Earnout Tranche") and $7.5 million ("Second Earnout Tranche"), respectively, upon the Company common stock achieving a price per share of $12.50 during the two-year period following the Closing or a price per share of $15.00 during the three-year period following the Closing Date, in each case, as its last reported sales price per share for any 20 trading days within any 30 consecutive trading day period within the applicable period ("Earnout Terms"); provided, that (i) if one or both of the share price triggers has not been achieved prior to the end of the three-year period following the Closing Date, (ii) the Company enters into a definitive agreement that would result in a change of control and (iii) the price per share of the Company’s common stock in such transaction is equal to or greater than one or both of the share price triggers, then at the Closing Date of such transaction, the Company shall issue the applicable portion of the Legacy TOI Earnout Shares as if such share price trigger had been achieved.

In addition, certain DFPH common stockholders deposited 575,000 shares of DFPH common stock in an escrow account that will vest and be released to such holders in two tranches of 50%, each (“DFPH Earnout Shares”), upon the Company common stock achieving the Earnout Terms as described above; provided, that (i) if one or both of the share price triggers has not been achieved prior to the end of the three-year period following the closing, (ii) the Company enters into a definitive agreement that would result in a change of control and (iii) the price per share of common stock in such transaction is equal to or greater than one or both of the share price triggers, then at the closing of such transaction, the Company shall issue the applicable portion of the DFPH Earnout Shares as if such share price trigger had been achieved. To the extent any DFPH Earnout Shares remain unvested at the expiration of the three-year period following the closing, such DFPH Earnout Shares shall be forfeited and cancelled without any consideration.

Collectively, the Legacy TOI Earnout Shares and DFPH Earnout Shares constitute the “Earnout Shares”, the “Earnout”, and the “Earnout Liability”.

The Company issued Legacy TOI Earnout Shares to Legacy TOI option holders and Legacy RSU holders (“Option-holders Earnout” and “RSU-holders Earnout”, respectively, together “Employees Earnout Shares”).

The Option-holders Earnout vests upon the Company common stock achieving the price per share as provided above, so long as the optionee has remained continuously employed by the Company at that date. The RSU-holders Earnout vests upon (a) the Company common stock achieving the price per share as provided above, and (b) the underlying RSU vested, so long as the optionee has remained continuously employed by the Company at that date.

The grant date fair value of the First Earnout Tranche and Second Earnout Tranche as of Closing Date was determined to be $8.35 and $6.76, respectively. The assumptions used in the Monte-Carlo Simulation model for the Earnout Shares granted on the Closing Date are provided in the following table:

As of September 30, 2023, there was $183 of unrecognized compensation expense related to the Employees Earnout Shares, which are expected to vest. That cost is expected to be recognized over a weighted average period of 0.37 years as of September 30, 2023. As of September 30, 2023, none of the Employee Earnout Shares have vested.

Note 15. Commitments and Contingencies

The Company evaluates contingencies based upon available evidence. In addition, allowances for losses are provided each year for disputed items which have continuing significance. The Company believes that allowances for losses have been provided to the extent necessary, and that its assessment of contingencies is reasonable. Due to the inherent uncertainties and subjectivity involved in accounting for contingencies, there is at least a reasonable possibility that recorded estimates will change by a material amount in the near term. To the extent that the resolution of contingencies results in amounts which vary from management’s estimates, future operating results will be charged or credited. The principal commitments and contingencies are described below.

Legal Matters

The Company is subject to certain outside claims and litigation arising in the ordinary course of business. In the opinion of Management, the outcome of such matters will not have a material effect on the Company’s condensed consolidated financial statements. Loss contingencies entail uncertainty and a possibility of loss to an entity. If the loss is probable and the amount of loss can be reasonably estimated, the loss should be accrued according to ASC No. 450-20, Disclosure of Certain Loss Contingencies.

Indemnities

The Company’s Articles of Incorporation and bylaws require it, among other things, to indemnify the director or officer against specified expenses and liabilities, such as attorneys’ fees, judgments, fines, and settlements, paid by the individual in connection with any action, suit, or proceeding arising out of the individual’s status or service as its director or officer, other than liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest, and to advance expenses incurred by the individual in connection with any proceeding against the individual with respect to which the individual may be entitled to indemnification by the Company. The Company also indemnifies its lessor in connection with its facility lease for certain claims arising from the use of the facilities. These indemnities do not provide for any limitation of the maximum potential future payments it could be obligated to make. Historically, the Company has not incurred any payments for these obligations and, therefore, no liabilities have been recorded for these indemnities in the accompanying Condensed Consolidated Balance Sheets.

The Health Insurance Portability and Accountability Act

The Health Insurance Portability and Accountability Act (“HIPAA”) assures health insurance portability, reduces healthcare fraud and abuse, guarantees security and privacy of health information, and enforces standards for health information. Organizations are required to be in compliance with HIPAA provisions. The Health Information Technology for Economic and Clinical Health Act (“HITECH”) imposes notification requirements in the event of certain security breaches relating to protected health information. Organizations are subject to significant fines and penalties if found not to be compliant with the provisions outlined in the regulations. The Company believes it is in compliance with these laws.

Table of Contents

Regulatory Matters

Laws and regulations governing the Medicare program and healthcare generally, are complex and subject to interpretation. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing. While no regulatory inquiries have been made, compliance with such laws and regulations can be subject to future government review and interpretation as well as significant regulatory action including fines, penalties, and exclusion from the Medicare and Medi-Cal programs.

Many of the Company’s payor and provider contracts are complex in nature and may be subject to differing interpretations regarding amounts due for the provision of medical services. Such differing interpretations may not come to light until a substantial period of time has passed following contract implementation. Liabilities for claims disputes are recorded when the loss is probable and can be estimated. Any adjustments to reserves are reflected in current operations. The Company does not have any reserves for regulatory matters as of September 30, 2023 and December 31, 2022.

Liability Insurance

The Company believes that its insurance coverage is appropriate based upon the Company’s claims experience and the nature and risks of the Company’s business. In addition to the known incidents that have resulted in the assertion of claims, the Company cannot be certain that its insurance coverage will be adequate to cover liabilities, arising out of claims asserted against the Company or the Company’s affiliated professional organizations, in the future where the outcomes of such claims are unfavorable.

The Company believes that the ultimate resolution of all pending claims, including liabilities in excess of the Company’s insurance coverage, will not have a material adverse effect on the Company’s financial position, results of operations or cash flows; however, there can be no assurance that future claims will not have such a material adverse effect on the Company’s business. Contracted physicians are required to obtain their own insurance coverage.

Guarantees

The Company, along with certain of the Company's subsidiaries from time to time party to the Facility Agreement (“Guarantors”), have pledged a first priority perfected lien on substantially all of their respective personal and real property, as collateral security for the payment of outstanding obligations, under the Facility Agreement.

Note 16. Business Combinations

During the year ended December 31, 2022, the Company closed on five business combinations and one asset acquisition. There were no business combinations or asset acquisitions during the three months ended September 30, 2023. There was one business combination and no asset acquisitions during the nine months ended September 30, 2023.

Practice Acquisitions

For the acquisition of various clinical practices, the Company applied the acquisition method of accounting, where the total purchase price was allocated, or preliminarily allocated, to the tangible and intangible assets acquired and liabilities assumed, based on their fair values as of the acquisition dates.

Perkins Practice Acquisition

On April 30, 2022 ("Perkins Acquisition Date"), the Company acquired certain non-clinical assets of California Oncology of the Central Valley Medical Group, Inc., (the “Perkins Practice”) from Christopher Perkins, M.D. (“Dr. Perkins”). Further, TOI CA acquired certain clinical assets of the Perkins Practice from Dr. Perkins. In conjunction with the acquisition, the Company also entered into a Professional Service Agreement with Oncology Associates of Fresno Medical Group, Inc. Intangible assets of $70 were recognized pursuant to the acquisition in the form of trade names of $2,480 and clinical contracts of $70, with weighted average amortization periods of 10 years and 5 years, respectively. The Company transferred cash consideration of $8,920 and contingent consideration of $2,000 to Dr. Perkins for the purchase. The contingent cash consideration was to be paid in two equal installments on the first and second anniversary of the transaction closing date (April 29, 2023 and 2024, respectively), pending Dr. Perkins' continued employment at that time. Dr. Perkins terminated his employment with the Company before the first anniversary date, therefore no contingent consideration is payable.

The Perkins Practice Acquisition was determined to constitute a business combination in accordance with ASC 805.

The deferred cash consideration liability will be remeasured at each reporting period until the contingent milestone is achieved or the liability is settled. Any changes in the fair value of the deferred cash consideration liability will be recognized in the Statements of Operations.

Summary of Consideration Transferred

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Such assets include synergies the Company expects to achieve, such as the use of the Company's existing infrastructure to support the added membership, and future economic benefits arising from the assembled workforce. The purchase consideration for the acquisitions has been allocated under the acquisition method of accounting to the estimated fair market value of the net assets acquired including a residual amount of tax deductible goodwill as noted in the fair value table below.

Acquisition costs amounted to $41 and $166 for the three months ended September 30, 2023 and 2022 respectively, and $112 and $700 for the nine months ended September 30, 2023 and 2022 respectively, were recorded as “General and administrative expenses” in the accompanying Condensed Consolidated Statements of Operations.

The following table summarizes the fair values assigned to identifiable assets acquired and liabilities assumed.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis provides information that management believes is relevant to an assessment and understanding of the consolidated results of operations and financial condition of The Oncology Institute, Inc. ("TOI") along with its consolidating subsidiaries (the "Company"). The discussion should be read together with the unaudited condensed consolidated financial statements and the related notes that are included elsewhere in this Report. The information in this discussion contains forward-looking statements within the meaning of Section 27A of the Securities Act, as amended, and Section 21E of the Securities and Exchange Act of 1934, as amended. Such statements are based upon current expectations, as well as management's beliefs and assumptions and involve a high degree of risk and uncertainty. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Statements that include the words "believes," "anticipates," "plans," "expects." "intends," and similar expressions that convey uncertainty of future events or outcomes are forward-looking statements. Our actual results could differ materially from those discussed or suggested in the forward-looking statements herein. Factors that could cause or contribute to such differences include those described under the heading "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2022 and in our Quarterly Report on Form 10-Q for the three months ended March 31, 2023. In addition, as a result of these and other factors, our past financial performance should not be relied on as an indication of future performance. All forward-looking statements in this document are based on information available to us as of the filing date of this Quarterly Report on Form 10-Q and we assume no obligation to update any forward-looking statements or the reasons why our actual results may differ. All dollar values are expressed in thousands, unless otherwise noted.

Overview

The Company is a leading value-based oncology company that manages community-based oncology practices that serve patients at 84 clinic locations across 15 markets and five states throughout the United States. Our community-based oncology practices are staffed with 123 oncologists and advanced practice providers. 70 of these clinics are staffed with 112 providers employed or contracted by our affiliated physician-owned professional corporations, referred to as the "TOI PCs", which provided care for more than 64,000 patients in 2022 and managed a population of approximately 1.8 million patients under value-based agreements as of September 30, 2023. The Company also provides management services on behalf of 14 clinic locations owned by independent oncology practices. The Company's mission is to heal and empower cancer patients through compassion, innovation, and state-of-the-art medical care.

Operationally, the Company’s medical centers provide a complete suite of medical oncology services including: physician services, in-house infusion and pharmacy, clinical trials, radiation, educational seminars, support groups, counseling, and 24/7 patient assistance. Many of our services, such as managing clinical trials, palliative care programs and stem cell transplants, are traditionally accessed through academic and tertiary care settings, while the TOI PCs bring these services to patients in a community setting. As scientific research progresses and more treatment options become available, cancer care is shifting from acute care episodes to chronic disease management. With this shift, it is increasingly important for high-quality, high-value cancer care to be available in a local community setting to all patients in need.

As a value-based oncology company, the Company seeks to deliver both better quality care and lower cost of care. The Company works to accomplish this goal by reducing wasteful, inefficient or counterproductive care that drives up costs but does not improve outcomes. The Company believes payors and employers are aligned with the value-based model due to its enhanced access, improved outcomes, and lower costs. Patients under the Company's affiliated providers’ care can benefit from evidence-based and personalized care plans, gain access to sub-specialized care in convenient community locations, and lower out-of-pocket costs. The Company believes its affiliated providers enjoy the stability and predictability of a large multi-state practice, are not incentivized or pressured to overtreat when it may be inconsistent with a patient’s goals of care, and can focus on practicing outstanding evidence-based medicine, rather than business building.

The Business Combination

On June 28, 2021, DFP Healthcare Acquisition Corp. ("DFPH"), Orion Merger Sub I, Inc. ("First Merger Sub") and Orion Merger Sub II, LLC ("Second Merger Sub") entered into an agreement and plan of merger ("Merger Agreement") with The Oncology Institute, LLC ("TOI LLC") (which was formerly known as TOI Parent, Inc.) (collectively, the "Business Combination"). In connection with the Business Combination, DFPH entered into subscription agreements with certain investors (the “PIPE Investors”), whereby it issued 17.5 million shares of common stock at $10.00 per share and 100,000 shares of preferred stock at $1,000.00 per share (“PIPE Shares”) for an aggregate investment of $275,000 (“PIPE Investment”), which closed simultaneously with the consummation of the Business Combination.

The Business Combination closed on November 12, 2021 ("Closing Date"). On the Closing Date, (i) First Merger Sub merged with and into the former TOI Parent, Inc., with the former TOI Parent, Inc. being the surviving corporation and (ii)

46

Table of Contents

immediately following, the former TOI Parent, Inc. merged with and into Second Merger Sub ("Legacy TOI"), with Second Merger Sub being the surviving entity and a wholly owned subsidiary of DFPH. DFPH was renamed “The Oncology Institute, Inc.” and TOI Common Stock and Public Warrants continued to be listed on Nasdaq under the ticker symbols “TOI” and “TOIIW,” respectively.

The total merger consideration on the Closing Date was $762,052, consisting of 51.3 million shares of common stock, valued at $10.00 per share (aggregate $595,468, inclusive of shares of DFPH common stock issuable per restricted stock units and the exercise of Legacy TOI stock options), and $166,584 in cash. Legacy TOI also issued 12.5 million shares of common stock pursuant to the terms of an earnout (“Earnout Shares”). The earnout shares are allocable to both Legacy TOI stockholders and Legacy TOI option holders. On the Closing Date, shares of DFPH common stock that were not otherwise redeemed as part of the DFPH public stockholder vote and the PIPE Shares automatically converted into shares of TOI stock on a one-for-one basis.

The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. generally accepted accounting principles (“U.S. GAAP"). Under this method of accounting, DFPH was treated as the “acquired” company for accounting purposes and the Business Combination was treated as the equivalent of Legacy TOI issuing stock for the net assets of DFPH, accompanied by a recapitalization. The net assets of DFPH are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination were those of Legacy TOI.

Components of Results of Operations

Revenue

The Company receives payments from the following sources for services rendered: (i) commercial insurers; (ii) pharmacy benefit managers (“PBMs”), (iii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”); (iv) state governments under Medicaid and other programs; (v) other third-party payors and managed care organizations (e.g., risk bearing organizations and independent practice associations (“IPAs”)); and (vi) individual patients and clients.

Revenue primarily consists of capitation revenue, fee-for-service (“FFS”) revenue, dispensary revenue, and clinical trials revenue. Capitation and FFS revenue comprise the revenues within the Company’s patient services segment and are presented together in the results of operations. The following paragraphs provide a summary of the principal forms of our billing arrangements and how revenue is recognized for each type of revenue.

Capitation

Capitation revenues consist primarily of fees for medical services provided by the TOI PCs to the Company's patients under a capitated arrangement with various managed care organizations. Capitation revenue is paid monthly based on the number of enrollees by the contracted managed care organization (per member per month or “PMPM”). Capitation contracts generally have a legal term of one year or longer. Payments in capitation contracts are variable since they primarily include PMPM fees associated with unspecified membership that fluctuates throughout the term of the contract; however, based on our experience, our total underlying membership generally increases over time as penetration of Medicare Advantage products grows. Certain contracts include terms for a capitation deduction where the cost of out-of-network referrals of members are deducted from the future payment. Revenue is recognized in the month services are rendered on the basis of the transaction price established at that time.

Fee-for-service revenue

FFS revenue represents revenue earned under contracts in which we bill and collect for medical services rendered by the TOI PCs’ employed physicians. The terms for FFS contracts are short in duration and only last for the period over which services are rendered (typically, one day). FFS revenue consists of fees for medical services provided to patients. As specialist providers, our FFS revenue is dependent on referrals from other physicians, such as primary care physicians. The Company's affiliated providers build trusted, professional relationships with these physicians and their associated medical groups, which can lead to recurring FFS volume; however, this volume is subject to numerous factors the Company cannot control and can fluctuate over time. The Company also receives FFS revenue for capitated patients that receive medical services which are excluded from the Company's capitation contracts. Under the FFS arrangements, third-party payors and patients are billed for patient care services provided by the TOI PCs. Payments for services provided are generally less than billed charges. The Company records revenue net of an allowance for contractual adjustments, which represents the net revenue expected to be collected from third-party payors (including managed care, commercial, and governmental payors such as Medicare and Medicaid), and patients. These expected collections are based on fees and negotiated payment rates in the case of third-party

payors, the specific benefits provided for under each patient’s healthcare plan, mandated payment rates in the case of Medicare and Medicaid programs, and historical cash collections (net of recoveries). The recognition of net revenue (gross charges less contractual allowances) from such services is dependent on certain factors, such as the proper completion of medical charts following a patient visit, the forwarding of such charts to our billing center for medical coding and entering into the Company's billing system, and the verification of each patient’s submission or representation at the time services are rendered as to the payor(s) responsible for payment of such services. Revenue is recorded on the date the services are rendered based on the information known at the time of entering of such information into the Company's billing systems as well as an estimate of the revenue associated with medical services.

Dispensary

Oral prescription drugs prescribed by doctors to their patients are sold directly through the TOI PCs’ dispensaries. Revenue for the prescriptions is based on fee schedules set by various PBMs and other third-party payors. The fee schedule is often subject to direct and indirect remuneration (“DIR”) fees, which are based primarily on pre-established metrics. DIR fees may be assessed in the periods after payments are received against future payments. The Company recognizes revenue, deducted by estimated DIR fees, at the time the patient takes possession of the oral drug.

Clinical trials & other revenue

The TOI PCs also enter into contracts to perform clinical research trials. The terms for clinical trial contracts last many months as the clinical research is performed. Each contract represents a single, integrated set of research activities that are satisfied over time as the output of results from the trial is captured for the trial sponsor to review. Under the clinical trial contracts, the TOI PCs receive a fixed payment for administrative, set-up, and close-down fees; a fixed amount for each patient site visit; and certain expense reimbursements. The Company recognizes revenue for these arrangements on the fees earned to date based on the state of the trial, as established under contract with the customer.

Operating Expenses

Direct costs - patient services

Direct costs - patient services primarily includes chemotherapy drug costs, clinician salaries and benefits, and medical supplies. Clinicians include oncologists, advanced practice providers such as physician assistants and nurse practitioners, and registered nurses employed by the TOI PCs.

Direct costs - dispensary

Direct costs - dispensary primarily includes the cost of oral medications dispensed in the TOI PCs’ clinic locations.

Direct costs - clinical trials & other

Direct costs - clinical trials & other primarily includes costs related to clinical trial contracts and medical supplies.

Selling, general and administrative expense

Selling, general and administrative expenses include employee-related expenses, including both clinic and field support staff as well as central administrative and corporate staff. These expenses include salaries and related costs and stock-based compensation for our executives and physicians. The Company's selling, general and administrative expenses also includes occupancy costs, technology infrastructure, operations, clinical and quality support, finance, legal, human resources, and business development. Following the consummation of the Business Combination, general and administrative expenses have increased, and the Company expects continued increases over time, due to the additional legal, accounting, insurance, investor relations and other costs that the Company incurs as a public company, as well as other costs associated with continuing to grow the business. While the Company expects its selling, general and administrative expenses to increase in absolute dollars in the foreseeable future. such expenses are on average expected to decrease as a percentage of revenue over the long term.

(1)     Includes independent oncology practices to which we provide limited management services, but do not bear the operating costs.

(2) Adjusted EBITDA is a "non-GAAP" financial measure within the meaning of Item 10 of Regulation S-K promulgated by the SEC. The Company defines Adjusted EBITDA as net income (loss) adjusting for:

•Depreciation and amortization,

•Interest expense, net,

•Income tax expense,

•Non-cash addbacks,

•Share-based compensation,

•Goodwill impairment charges

•Changes in fair value of liabilities,

•Unrealized (gains) losses on investments

•Practice acquisition-related costs,

•Post combination compensation expense,

•Consulting and legal fees,

•Infrastructure and workforce costs, and

•Transaction costs.

The Company includes Adjusted EBITDA because it is an important measure which our management uses to assess the results of operations, to evaluate factors and trends affecting the business, and to plan and forecast future periods.

Management believes that this measure provides an additional way of viewing aspects of the Company's operations that, when viewed with the GAAP results, provides a more complete understanding of the Company's results of operations and the factors and trends affecting the business. However, non-GAAP financial measures should be considered a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with U.S. GAAP. Non-GAAP financial measures used by management may differ from the non-GAAP measures used by other companies, including the Company's competitors. Management encourages investors and others to review the Company's financial information in its entirety, not to rely on any single financial measure.

Liquidity and Capital Resources

General

To date, the Company has financed its operations principally through debt facilities, issuances of equity securities and payments received from various payors. As of September 30, 2023, the Company had $27,535 of cash and cash equivalents, current marketable securities of $59,877, and noncurrent marketable securities of $0.

The Company expects to incur operating losses and generate negative cash flows from operations for the foreseeable future due to the investments management intends to continue to make in expanding operations and sales and marketing and due to additional general and administrative expenses management expects to incur in connection with operating as a public company. As a result, the Company may require additional capital resources to execute strategic initiatives to grow the business.

Management believes that the cash on hand and investments in marketable securities will be sufficient to fund the Company's operating and capital needs for at least the next 12 months. Management's assessment of the period of time through

Table of Contents

which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties. The Company's actual results could vary because of, and its future capital requirements will depend on, many factors, including our growth rate, the timing and extent of spending to open or acquire new clinics and expand into new markets and the expansion of sales and marketing activities. The Company may in the future enter into arrangements to acquire or invest in complementary businesses, services and technologies, including intellectual property rights. The Company has based this estimate on assumptions that may prove to be wrong, and the Company could use its available capital resources sooner than management currently expects. The Company may be required to seek additional equity or debt financing. In the event that additional financing is required from outside sources, the Company may not be able to raise it on terms acceptable to management or at all. If unable to raise additional capital when desired, or if the Company cannot expand operations or otherwise capitalize on business opportunities because the Company's lack of sufficient capital, the Company's business, results of operations, and financial condition would be adversely affected.

Outside of the aforementioned, and any routine transactions made in the ordinary course of business, there have been no significant changes to our material cash requirements as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

Operating Activities

Significant changes impacting net cash, cash equivalents, and restricted cash used in operating activities for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 were as follows:

•Net loss of $64,314 for the nine months ended September 30, 2023 compared to net income of $11,159 for the nine months ended September 30, 2022, primarily as the result of goodwill impairment of $16,867 for the nine months ended September 30, 2023 that did not occur the prior year, and a decrease of $66,892 in the gain related to the change in fair value of liabilities compared to the prior year;

•Share based compensation for the nine months ended September 30, 2023 decreased by $7,882 compared to the nine months ended September 30, 2022;

•Cash used by accounts receivable decreased $6,558 for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 due to the growth in the Company's business;

•Cash provided by accounts payable, accrued expenses and income taxes payable increased $5,795 for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 primarily due to an increase in vendor payables due to the growth in the Company's business; and

•Cash provided by prepaid and other current assets decreased $817 for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 primarily due to the amortization of the D&O policy during 2023 and costs incurred in association with the SPAC transaction during 2022 that were deferred until the transaction closed.

Investing Activities

Net cash provided by investing activities increased $150,056 for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 due to sales of marketable securities of $68,702, and purchases of $77,719 that did not occur in the current period.

Financing Activities

Net cash used in financing activities decreased $98,119 for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022 primarily due to $110,000 debt issuance that did not occur in the current period offset by $7,981 decrease in stock repurchase.

JOBS Act

The Company qualifies as an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and has elected to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company that is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Critical Accounting Policies

The Company prepares its financial statements in accordance with generally accepted accounting principles in the United States ("U.S. GAAP"), which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates under different assumptions or conditions.

Leases

On January 1, 2022, the Company adopted ASU 2016-02, Leases, with various amendments issued in 2018 and 2019 (collectively, “ASC 842”) using the modified retrospective approach, for leases that existed on January 1, 2022. ASC 842 requires lessees to recognize assets and liabilities for most leases. The Company evaluates whether an arrangement is or contains a lease at contract inception. A lease exists when a contract conveys to the customer the right to control the use of an identified asset for a period of time in exchange for consideration. Upon lease commencement, the date on which a lessor makes the underlying asset available to the Company for use, the Company classifies the lease as either an operating or finance lease. The Company applied certain practical expedients permitted under the transition guidance, including the package of practical expedients, which permits the Company not to reassess its prior conclusions related to lease identification, lease classification, and initial direct costs capitalization. The Company solely acts as a lessee and its leases primarily consist of operating leases for its real estate in the states in which the Company operates. The Company has other operating or financing leases for various clinical and non-clinical equipment.

Generally, upon the commencement of a lease, the Company will record a right-of-use (“ROU”) asset and lease liability. An ROU asset represents the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease liabilities are measured at the present value of the remaining, fixed lease payments at lease commencement. The Company uses its incremental borrowing rate, based on the information available at the later of adoption, inception, or modification in determining the present value of lease payments.

57

Table of Contents

ROU assets are measured at an amount equal to the initial lease liability, plus any prepaid lease payments (less any incentives received) and initial direct costs, at the lease commencement date. The Company has elected to account for lease and non-lease components as a single lease component for all underlying classes of assets. As a result, the fixed payments that would otherwise be allocable to the non-lease components are accounted for as lease payments and included in the measurement of the Company’s right-of-use asset and lease liability.

Lease arrangements with an initial term of 12 months or less are considered short-term leases and are not recorded on the balance sheet. The short-term lease payments are recognized as an expense on a straight-line basis over the lease term. The lease term includes any period covered by renewal options available that the Company is reasonably certain to exercise and any options to terminate the lease that the Company is not reasonably certain to exercise.

Variable Interest Entities

The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. The Company holds variable interests in the TOI PCs, comprised of TOI CA, TOI FL, and TOI TX all of which the Company cannot legally own due to jurisdictional laws governing the corporate practice of medicine. The TOI PCs employ physicians and other clinicians in order to provide professional services to patients of our managed clinics, and under substantially similar MSAs, we serve as the exclusive manager and administrator of the TOI PCs’ non-medical functions and services. The TOI PCs are considered variable interest entities (“VIEs”) as they do not have sufficient equity to finance their activities without additional financial support from the Company. An enterprise having a controlling financial interest in a VIE must consolidate the VIE if it has both power and benefits — that is, it has (1) the power to direct the activities of a VIE that most significantly impacts the VIE’s economic performance (power), and (2) the obligation to absorb the losses of the VIE that potentially could be significant to the VIE or the right to receive benefits from the VIE that potentially could be significant to the VIE (benefits). The Company has the power to control all financial activities of the TOI PCs, the rights to receive substantially all benefits from the VIEs, and consequently consolidates the TOI PCs. Revenues, expenses, and income from the TOI PCs are included in the consolidated amounts as presented on the Condensed Consolidated Statements of Operations.

Segment Reporting

The Company presents the financial statements by segment in accordance with the relevant accounting literature to provide investors with transparency into how the chief operating decision maker (“CODM”) manages the business. The Company's CODM is our Chief Executive Officer. The CODM reviews financial information and allocates resources across three operating segments: dispensary, patient care, and clinical trials & other.

Revenue Recognition

The Company recognizes consolidated revenue based upon the principle of the transfer of control of our goods and services to customers in an amount that reflects the consideration to which it expects to be entitled. This principle is achieved through applying the following five-step approach:

1.Identification of the contract, or contracts, with a customer.

2.Identification of the performance obligations in the contract.

3.Determination of the transaction price.

4.Allocation of the transaction price to the performance obligations in the contract.

5.Recognition of revenue when, or as, the entity satisfies a performance obligation.

Consolidated revenue primarily consists of capitation revenue, fee-for-service (FFS) revenue, dispensary revenue, and clinical trials revenue. Revenue is recognized in the period in which services are rendered or the period in which the TOI PCs are obligated to provide services. The form of billing and related risk of collection for such services may vary by type of revenue and the payor. The following paragraphs provide a summary of the principal forms of billing arrangements and how revenue is recognized for each.

Capitation

Capitation contracts have a single performance obligation that is a stand ready obligation to perform specified healthcare services to the population of enrolled members and constitutes a series for the provision of managed healthcare services for the term of the contract, which is deemed to be one month since the mix of patient-customers can and do change month over

58

Table of Contents

month. The transaction price for capitation contracts is variable as it primarily includes PMPM fees associated with unspecified membership that fluctuates throughout the term of the contract. Further, we adjust the transaction price for capitation deductions based on historical experience. Revenue is recognized in the month services are rendered on the basis of the transaction price established at that time. If subsequent information resolves uncertainties related to the transaction price, adjustments will be recognized in the period they are resolved. When payment has been received but services have not yet been rendered, the payment is recognized as a contract liability.

Fee For Service

FFS revenue consists of fees for medical services actually provided to patients. These medical services are distinct since the patient can benefit from the medical services on their own. Each service constitutes a single performance obligation for which the patient accepts and receives the benefit of the medical services as they are performed.

The transaction price from FFS arrangements is variable in nature because fees are based on patient encounters, credits due to patients, and reimbursement of provider costs, all of which can vary from period to period. The Company estimates the transaction price using the most likely methodology and amounts are only included in the net transaction price to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. As a practical expedient, the Company adopted a portfolio approach to determine the transaction price for the medical services provided under FFS arrangements. Under this approach, the Company bifurcated the types of services provided and grouped health plans with similar fees and negotiated payment rates.

At these levels, portfolios share the characteristics conducive to ensuring that the results do not materially differ from the standard applied to individual patient contracts related to each medical service provided.

Revenue is recorded on the date the services are rendered based on the information known at the time of entering of such information into our billing systems as well as an estimate of the revenue associated with medical services. When the performance obligation is not satisfied, the billing is recognized as a contract liability.

Dispensary

Dispensed prescriptions that are filled and delivered to the patient are considered a distinct performance obligation. The transaction price for the prescriptions is based on fee schedules set by PBMs and other third-party payors. The fee schedule is often subject to DIR fees, which are based primarily on pre-established metrics. DIR fees may be assessed in periods after payments are received against future payments. The Company estimates DIR fees to arrive at the transaction price for prescriptions. Revenue is recognized based on the transaction at the time the patient takes possession of the oral drug.

Clinical Research & Other

Clinical research contracts represent a single, integrated set of research activities and thus are a single performance obligation. The performance obligation is satisfied over time as the output is captured in data and documentation that is available for the customer to consume over the course of arrangement and furthers progress of the clinical trial. The Company has elected to recognize revenue for clinical trials using the ‘as-invoiced’ practical expedient. The customer is invoiced periodically based on the progress of the trial such that each invoice captures the revenue earned to date based on the state of the trial as established under contract with the customer.

Direct Costs of Sales

Direct cost of sales primarily consists of wages paid to clinical personnel and other health professionals, oral and IV drug costs, and other medical supplies used to provide patient care. Costs for clinical personnel wages are expensed as incurred and costs for inventory and medical supplies are expensed when used, generally by applying the specific identification method.

Goodwill and Intangible Assets

The Company accounts for goodwill and intangible assets under Accounting Standards Codification Topic No. 350, Goodwill and Other (“ASC 350”). Goodwill represents the excess of the fair value of the consideration conveyed in acquisition over the fair value of net assets acquired.

Goodwill is not amortized but is required to be evaluated for impairment at the same time every year. The Company performs annual testing of impairment for goodwill in the fourth quarter of each year or earlier if potential impairment indicators exist. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying

59

Table of Contents

amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit.

Under ASC 350, finite-lived intangible assets are stated at acquisition-date fair value. Intangible assets are amortized using the straight-line method.

Finite-lived intangible assets are stated at acquisition-date fair value. Intangible assets are amortized using the straight-line method. Finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When circumstances indicate that recoverability may be impaired, the Company assesses its ability to recover the carrying value of the asset group from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset, an impairment loss is recognized for the difference between estimated fair value and carrying value. Fair value is determined based on appropriate valuation techniques.

Item 3. Quantitative and Qualitative Disclosures About Market Risk 

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of exposure due to potential changes in inflation or interest rates. We do not hold financial instruments for trading purposes.

Interest Rate Risk

We held cash and cash equivalents of $27,535, current marketable securities of $59,877, and noncurrent marketable securities of $0 as of September 30, 2023, consisting of bank deposits. Such interest-earning instruments carry a degree of interest rate risk. The goals of our investment policy are liquidity and capital preservation. We believe that we do not have any material exposure to changes in the fair value of these assets as a results of changes in interest rates due to the short-term nature of our cash and cash equivalents.

Inflation Risk

Recently, inflation has increased throughout the U.S. economy. Inflation can adversely affect us by increasing the costs of drugs, clinical trials and research, administration and other costs of doing business. We may experience increases in the prices of labor and other costs of doing business. In an inflationary environment, cost increases may outpace our expectations, causing us to use our cash and other liquid assets faster than forecasted. If this happens, we may need to raise additional capital to fund our operations, which may not be available in sufficient amounts or on reasonable terms, if at all, sooner than expected.

Impairment Risk

Impairment risk refers to the risk that the Company will write down a material amount of its goodwill or intangible assets. This risk is assessed at least annually in the fourth quarter each year when the Company performs its impairment testing. To the extent that, among other factors, (i) there is underperformance in one or more reporting units (ii) a potential recession further disrupts the economic environment or (iii) interest rates continue to rise in response to persistent inflation, the fair value of one or more of the reporting units could fall below their carrying value, resulting in a goodwill or intangible impairment charge.

For the three and nine months ended September 30, 2023, the Company recognized an impairment charge of $0 and $16,867, respectively to write-down the carrying value of goodwill related to patient services and clinical trials & other in excess of the fair value.

Item 4. Controls and Procedures 

Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to ensure that the information relating to our Company, including our consolidated subsidiaries, that are required to be disclosed in our SEC reports, is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosure. We conducted an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of September 30, 2023. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2023, our disclosure controls and procedures were not effective due to a material weakness in our internal

60

Table of Contents

control over financial reporting, as described below. Notwithstanding the identified material weakness noted below, management, including our Chief Executive Officer and Chief Financial Officer, who serve as our principal executive officer and principal financial officer, respectively, believe the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly represent, in all material respects, our financial condition, results of operations and cash flows as of and for the periods presented in accordance with GAAP.

Material Weakness in Internal Controls Over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

As of September 30, 2023, we have identified a material weakness in our internal control over financial reporting of complex accounting transactions, as previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

During the third quarter of 2023, our management continued to execute against the remediation plan under the oversight of the Audit Committee. This involves hiring and training additional qualified personnel, performing detailed risk assessments in key process areas to identify risks of material misstatement, further documenting and implementing control procedures to address the identified risk of material misstatement, and implementing monitoring activities over such control procedures.

Changes in Internal Control over Financial Reporting

Except for the changes in the Company's internal control that have been made toward remediating the material weakness noted above, there were no changes in the Company’s internal control over financial reporting that occurred during the three months ended September 30, 2023 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on Effectiveness of Disclosure Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management, including the Chief Executive Officer and Chief Financial Officer, recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II

Item 1. Legal Proceedings

From time to time, we may be involved in various legal proceedings and subject to claims that arise in the ordinary course of business. Although the results of litigation and claims are inherently unpredictable and uncertain, we are not currently a party to any legal proceedings the outcome of which, if determined adversely to us, are believed to, either individually or taken together, have a material adverse effect on our business, operating results, cash flows or financial condition.

Item 1A. Risk Factors 

There have been no material changes to the risk factors previously described in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and in Part II Item 1A of our Quarterly Report for the three months ended March 31, 2023. These risk factors describe some of the assumptions, risks, uncertainties and other factors that could adversely affect our business or that could otherwise result in changes that differ materially from our expectations. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds 

On August 28, 2023 the Company's Board approved a share repurchase program with authorization to purchase up to 2 million shares of the Company's common stock. The Company repurchased $125 of its common stock in the third quarter of 2023. The table below reflects our purchases of common stock during each of the months in the three months ended September 30, 2023.

Period	Total Number of Shares of Stock Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Program	Maximum Number of Shares that May Yet be Purchased Under the Program

(b)The Executive will be eligible to receive an annual bonus payment of up to forty percent (40%) of the Executive’s then-current Base Salary based on the achievement of mutually agreed performance objectives determined in accordance with the Company’s annual budget (the “Bonus”); provided, that (i) the achievement of such Bonus shall be determined by the Board in its good faith discretion, and (ii) any Bonus payable for the Executive’s first calendar year with the Company will be pro-rated based on the Effective Date of this Agreement.

The Executive acknowledges and agrees that: (i) the Executive has a major responsibility for the operation, development and growth of the Company’s Business (as defined in Section 21(b) below); (ii) the Executive’s work for the Company has brought and will bring the Executive into close contact with Confidential Information (as defined in paragraph (a)(i) immediately below) of the Company and its direct and indirect subsidiaries (collectively, and together with their respective predecessors and successors, the “Company Group”) and each of their respective customers, vendors, suppliers, employees, and independent contractors; (iii) the agreements and covenants contained in this Section 4 are essential to protect the business interests of each member of the Company Group and

    - 2 -    

|US-DOCS\126616667.2||

their respective Affiliates; and (iv) the Company would not enter into this Agreement but for such agreements and covenants. Accordingly, the Executive covenants and agrees to the following:

(a)Confidential Information.

(i)Except as set forth below in Section 4(a)(ii), the Executive agrees to keep confidential and not disclose, directly or indirectly, to any Person or use in any way (other than for the benefit of the Company Group), both during the Employment Period and thirty-six (36) months after the Executive’s employment with the Company terminates (the “Non-Disclosure Period”), all Confidential Information concerning any member of the Company Group or any of their respective Affiliates, that was acquired by, or disclosed to, or developed on behalf of the Company by, the Executive during the course of the Executive’s employment with the Company or any of its Affiliates. For purposes of this Agreement, “Confidential Information” means, any written or oral proprietary or non-public information of any member of the Company Group or any of their respective Affiliates, including information relating to corporate or organizational documents, contracts, employees, independent contractors, customers, suppliers, sales, promotional, marketing, sales programs, credit history, repayment history, financial information, financial statements, costs, operations, trade secrets, know-how, research and development, software, databases, inventions, processes, technology, sales, pricing, vendors, compensation, marketing, advertising, promotions, product lines, alliances, financial data, plans, prospects, and government and regulatory activities, whether past, current or planned. “Confidential Information” does not include information that: (A) was, is now, or becomes generally available and known to the public or participants in the Company’s industry (but, in each case, not as a result of a breach of any duty of confidentiality by which the Executive or the disclosing party is bound); (B) is disclosed by the Company to any Person without a duty of confidentiality prior to disclosure to the Executive; or (C) is independently developed by the Executive without any reference to, or any use of, any Confidential Information and as provided in paragraph (c) below, not in connection with the Executive’s performance of legitimate business purposes on behalf of the Company with respect to the Executive’s employment with the Company. As to Confidential Information that constitutes a trade secret, the restrictions in this Section 4(a)(i) shall last for as long as the item qualifies as a trade secret under federal or state law. As to Confidential Information that does not constitute a trade secret, the restrictions in this Section 4(a)(i) shall last for so long as the Confidential Information remains confidential, unless applicable law requires a shorter duration and, if that is the case, the restrictions shall last during the Employment Period and for thirty-six (36) months after the Executive’s employment with the Company terminates.

(ii)Notwithstanding anything to the contrary set forth in Section 4(a)(i), the Executive may disclose Confidential Information to any Person (A) if, upon the opinion of the Executive’s counsel, such Confidential Information is required to be disclosed by applicable law, regulation or legal process, (B) in the ordinary course of the Company’s business as a proper part of the Executive’s employment in connection with communications with customers, vendors, suppliers, and other proper parties; provided, that it is for a proper purpose for the benefit of any member of the Company Group, and/or (C) to enforce the Executive’s rights under this Agreement or any other agreement between the Company or any of its Affiliates and the Executive or any of the Executive’s Affiliates. If the Executive is required to disclose any Confidential Information pursuant to Section 4(a)(ii)(A), the Executive shall give the Company prompt notice so that the applicable member of the Company Group may seek a protective order or other appropriate remedy and/or waive compliance with Section 4(a) and, in the event such protective order or other remedy is not obtained, or that the applicable member of the Company Group waives compliance with Section 4(a), the Executive shall (1) use commercially reasonable efforts to cooperate with, and assist, the applicable member of the Company Group in connection therewith, at the applicable member of the Company Group’s sole cost and expense, (2) disclose only that portion of the Confidential Information which is legally required to be disclosed, and (3) seek to obtain confidential treatment, at the applicable member of the Company Group’s sole cost and expense, for such Confidential Information.

(iii)Notwithstanding anything to the contrary set forth in Section 4(a)(i) or Section 4(a)(ii), the Executive understands that nothing contained in this Agreement limits or otherwise prohibits Executive’s ability to file a charge or complaint with the Department of Justice, the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission, any agency Inspector General, or any

    - 3 -    

|US-DOCS\126616667.2||

other federal, state or local governmental agency or commission (the “Government Agencies”), or to make other disclosures that are protected under the whistleblower provisions of state or federal law or regulation. The Executive further understands that this Agreement does not limit Executive’s ability to communicate with any of the Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any of the Government Agencies, including providing documents or other information, without notice to the Company. This Agreement does not limit Executive’s right to receive an award for information provided to any Government Agencies.

(iv)Pursuant to 18 U.S.C. § 1833(b)(1): “An individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (1) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney and (2) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.” Additionally, if Executive files a lawsuit against the Company for retaliation for reporting a suspected violation of law, Executive understands that Executive has the right to provide trade secret information to Executive’s attorney and use the trade secret information in the court proceeding, although Executive must file any document containing the trade secret under seal and Executive may not disclose the trade secret, except pursuant to court order.

(b)Non-Competition; Non-Solicitation.

(i)Subject to Section 4(b)(iii), the Executive agrees that, for the Employment Period, i.e., the period commencing on the Effective Date and ending on the date on which the Executive’s employment with the Company is terminated for any reason (such period also shall be referred to as the “Non-Competition Period”), the Executive shall not directly or indirectly, alone or in association with others, or as a partner, officer, director, employee, consultant, agent, independent contractor, lender, member, manager or equity holder, or on behalf, of any Person, engage in the Business or any business activity that is in competition with the Business of any member of the Company Group within the Restricted Territory.

(ii)The Executive agrees that, for the period commencing on the Effective Date and ending twenty four (24) months after the date on which the Executive’s employment with the Company is terminated for any reason (such period shall be referred to as the “Non-Solicitation Period”), the Executive shall not directly or indirectly, in any capacity, either alone, separately or in association with, or on behalf of, any other Person solicit for employment or any business relationship any current or former employee or independent contractor of any member of the Company Group who was employed or engaged by the Company within six (6) months of the solicitation and with whom Executive has had material personal contact, supervised or managed, or otherwise possesses Confidential Information or the Company’s goodwill; provided, however, that a general solicitation or advertisement of employment conducted by or on behalf of the Executive or any of the Executive’s Affiliates in newspapers, trade journals, the Internet, through recruiters or by any similar means, in each case, not specifically directed at any of the Company Group’s employees or independent contractors shall not, in and of itself, be deemed a breach of this subsection (ii).

(iii)Notwithstanding the restrictions set forth in Section 2 and/or Section 4(b)(i), nothing contained in Section 4(b) shall be deemed to prohibit the Executive during the Non-Competition Period from (A) being a passive owner of less than five percent (5%) of any class or series of outstanding securities of publicly traded securities of any entity or (B) volunteering in any capacity with any civic, educational or charitable organization, or any trade association, in each case without seeking or obtaining approval by the Company or the Board; provided, that in each case such activities and services do not materially interfere or conflict with the performance of the Executive’s duties hereunder or violate any of the Restrictive Covenants.

(c)Proprietary Rights. The Executive acknowledges and agrees that all right, title and interest in all developments, including inventions, patentable or otherwise, discoveries, improvements, patents, trade secrets, designs, reports, computer software, flow charts and diagrams, procedures, data, documentation, ideas and writings and applications thereof relating to the present or contemplated Business of any member of the Company Group that, alone or jointly with others, the

    - 4 -    

|US-DOCS\126616667.2||

Executive has already or may in the future during the Employment Period conceive, create, make, develop, reduce to practice or acquire (collectively, the “Developments”) are works made for hire and shall remain the sole and exclusive property of the Company, and the Executive hereby assigns to the Company all of the Executive’s right, title and interest in and to all such Developments, and such Developments shall not be used by the Executive in any way adverse to any member of the Company Group’s interests. All items related to the Developments, including memoranda, notes, lists, charts, drawings, records, files, computer software, programs, source and programming narratives and other documentation (and all copies thereof) made or compiled by the Executive, or made available to the Executive, during the Employment Period concerning the Business or planned business of any member of the Company Group shall be the property of the Company, and shall be delivered to the Company promptly upon the earlier of the Company’s request or the termination of this Agreement. The Executive shall not deliver, reproduce or in any way allow such documents or Developments to be delivered or used by any third party without the prior written approval of the Board. The Executive will promptly disclose all Developments to the Company and, at the Company’s expense, perform all reasonable actions requested by the Company (whether during or after employment) to establish and confirm such ownership (including assignments, consents, powers of attorney and other instruments). Pursuant to California Labor Code 2870, the foregoing provisions regarding the assignment of Developments to the Company does not apply to a Development for which no equipment, supplies, facility or trade secret information of the Company was used and which was developed entirely on the Executive’s own time, unless (i) the invention relates at the time of conception or use (A) to the business of the Company or (B) to the Company’s actual or demonstrably anticipated research or development, or (ii) the invention results from or is the product of any work performed by the Executive for the Company in the scope of the Executive’s efforts on behalf of the Company.

(d)Non-Disparagement. Except in order to comply with law, regulation or legal process, or to enforce (or defend) the Executive’s rights hereunder or any other agreement with any member of the Company Group or as described in Section 4(a)(iii) or Section 4(a)(iv), the Executive agrees not to make any public disparaging or negative remarks, whether oral or written, with respect to any member of the Company Group or any of their respective equity holders, officers, directors, managers, and/or employees.

(e)Remedies. If the Executive breaches any of the provisions contained in Section 4(a), Section 4(b), Section 4(c), or Section 4(d) (the “Restrictive Covenants”), the Company shall have the remedies set forth below, each of which shall be enforceable, and each of which is in addition to, and not in lieu of, any other rights and remedies available to the Company at law or in equity. The provisions of this Section 4 are intended to be for the benefit of each member of the Company Group and their respective Affiliates (for enforcement purposes only with respect to such Affiliates), each of which Person may enforce such provisions and each of which is an express third party beneficiary of such provisions and this Agreement generally. The Executive acknowledges and agrees that money damages would be an inadequate remedy for any breach of any of the Restrictive Covenants, and, in the event of a violation or a breach or threatened breach of any of the Restrictive Covenants, the Company may have no adequate remedy at law, and the Company, in addition to other rights and remedies existing in its favor, shall be entitled to specific performance, or to enforce each such provision by temporary or permanent injunction or mandatory relief, obtained in any court of competent jurisdiction without the necessity of proving damages, posting any bond or other security, and without prejudice to any other rights and remedies that may be available at law or in equity.

(f)Severability. If any of the Restrictive Covenants, or any part thereof, is held to be invalid or unenforceable, the same shall not affect the remainder of the covenant or covenants, which shall be given full effect, without regard to the invalid or unenforceable portion(s). Without limiting the generality of the foregoing, if any of the Restrictive Covenants, or any part thereof, is held to be unenforceable because of the scope of the activity restricted, the duration of such provision or the area covered thereby, the Parties agree that the court making such determination (or the Parties together themselves) shall have the power to reduce the scope of activity restricted, the duration and/or area of such provision and, in its reduced form, such provision shall then be enforceable.

(g)Enforceability. The Executive acknowledges that the restrictions and duration of the obligations set forth in this Section 4 (i) are reasonable and no broader than necessary to protect the

    - 5 -    

|US-DOCS\126616667.2||

legitimate business interests of the Company Group and the goodwill thereof and (ii) do not and will not impose an unreasonable burden upon the Executive. The Company and the Executive agree that if, at the time of enforcement of any of the provisions of this Section 4, a court holds that any restriction stated herein is unreasonable under circumstances then existing, then the maximum period, scope or geographical area reasonable under such circumstances will be substituted for the otherwise applicable period, scope or area. Subject to Section 4(b)(iii), in the event of any breach or violation by the Executive of any of the provisions of Section 4(a), Section 4(b)(i) or Section 4(b)(ii), the running of the Non-Disclosure Period, Non-Competition Period, or Non-Solicitation Period, as the case may be, shall be tolled during the continuation of any breach or violation by the Executive.

5.Termination and Compensation Due Upon Termination. The Employment Period shall continue until terminated in accordance with one of Section 5(a) through Section 5(f).

(a)Termination Without Cause. The Company shall have the right to terminate the Executive’s employment at any time during the Employment Period without Cause. If the Company terminates the Executive’s employment under this Agreement without Cause, the Company shall pay the Executive any compensation and benefits the Company owes to the Executive through the date of termination, in each case, as applicable, pursuant to and in accordance with Section 3 (collectively, the “Accrued Compensation and Benefits”). Additionally, conditioned upon the Executive’s voluntary execution of the Release of Claims Agreement in substantially the form of Exhibit A attached hereto, which Release of Claims Agreement shall be subject to modification only to the extent necessary to comply with changes in applicable law, if any, occurring after the Effective Date and prior to the date such Release of Claims Agreement is executed or by mutual agreement (the “Release”) (which must become effective on or prior to the sixtieth (60th) day following such termination), the Company shall pay to or on behalf of the Executive (i) the Executive’s Base Salary at the time of such termination for three (3) months thereafter (the “Severance Period”), plus (ii) subject to applicable law, payment or reimbursement of all premiums for medical benefits elected by the Executive pursuant to the continuation of medical coverage under Section 4980B of the Code (as defined below) and Sections 601 through 608, inclusive, of the Employee Retirement Income Security Act of 1974 (“ERISA”), which amounts shall be deemed to be taxable income to the Executive, during the Severance Period (collectively, the payments described in Section 5(a)(i) and Section 5(a)(ii) shall be referred to as the “Severance Payments”). Severance Payments required to be paid pursuant to (A) Section 5(a)(i) shall be paid during the Severance Period in accordance with Section 3(a) and (B) Section 5(a)(ii) shall be paid or reimbursed as when due or incurred by the Executive during the Severance Period in accordance with Section 3, as applicable. Notwithstanding anything in this Section 5(a), the Severance Payments shall be paid to the Executive, in accordance with the Company’s payroll policy, beginning on the payroll date which next occurs after the sixty first (61st) day following such termination; provided, that the Release is timely executed and delivered to the Company (and becomes effective) within such sixty (60) day period. All Severance Payments due from the date of termination of employment to the sixty first (61st) day following such termination shall be paid on the first payroll date of the Company following such period. If the Executive does not voluntarily execute the Release and the Release does not become effective within sixty (60) days of delivery of the Release by the Company to the Executive, the Executive shall not be entitled to the Severance Payments.

(b)Resignation with Good Reason. The Executive shall have the right to terminate the Executive’s employment with the Company during the Employment Period for Good Reason upon thirty (30) days’ written notice to the Company and the Board; provided, that such notice provides a reasonably detailed explanation of the event or circumstance that constitutes Good Reason and such event or circumstance remains uncured (if curable) for ten (10) days after the Company and the Board have received such written notice. If the Executive terminates the Executive’s employment with the Company for Good Reason during the Employment Period, the Executive will be entitled to all payments and benefits as if the Executive had been terminated without Cause pursuant to, and in accordance with, the terms and conditions set forth in Section 5(a) (including the Executive’s voluntary execution of the Release). The Executive’s right to receive the Severance Payments in connection with the termination of the Executive’s employment for Good Reason for any particular event or circumstance shall cease to exist solely with respect to such event or circumstance if the Executive fails to provide written notice to the Company and the Board of such event or circumstance within thirty (30) days after the Executive has actual knowledge of the occurrence or existence thereof.

    - 6 -    

|US-DOCS\126616667.2||

(c)Voluntary Resignation without Good Reason. The Executive may terminate the Executive’s employment with the Company for any reason (or no reason at all), other than Good Reason, at any time during the Employment Period by giving the Company sixty (60) days’ prior written notice of the Executive’s voluntary resignation; provided, however, that the Company may elect to waive all or any part of such notice period and/or that the Executive’s voluntary resignation be effective immediately upon notice of such resignation. The Company shall have no obligation to make any other payments to the Executive in accordance with the provisions of Section 3 (or otherwise in respect of the Executive’s employment) for periods after the date on which the Executive’s employment with the Company terminates due to the Executive’s voluntary resignation (other than for Good Reason), other than any Accrued Compensation and Benefits.

(d)Termination for Cause. The Company shall have the right to terminate the Executive’s employment at any time during the Employment Period for Cause; provided, that the Company has delivered written notice to the Executive of a reasonably detailed explanation of the event or circumstance that constitutes Cause and such event or circumstance remains uncured (if curable) for ten (10) business days after the Executive has received such written notice. If the Executive’s employment with the Company is terminated for Cause, the Company shall have no obligation to make any payments to the Executive in accordance with the provisions of Section 3 (or otherwise in respect of the Executive’s employment) for periods after the Executive’s employment with the Company is terminated on account of the Executive’s termination for Cause, other than any Accrued Compensation and Benefits. Any event or circumstance that constitutes Cause will be presumed to be curable, unless such event or circumstance arises from, relates to, or is in connection with any of clauses (i), (iii), (iv) (v), (vi), (vii) (viii) or (ix) in the definition of Cause.

(e)Disability. If, during the Employment Period, the Executive is unable to perform, with or without reasonable accommodation, the Executive’s essential job functions pursuant to and in accordance with this Agreement due to any physical or mental disability which exists for a period of one hundred eighty (180) days in any twelve (12) consecutive month period during the Employment Period, the Company shall have the right to terminate the Executive’s employment hereunder by giving not less than thirty (30) days’ prior written notice to the Executive, at the end of which time the Executive’s employment shall be terminated. Upon expiration of such thirty (30) day period, the Company shall have no obligation to make payments to the Executive in accordance with the provisions of Section 3 (or otherwise in respect of the Executive’s employment) for periods after the date the Executive’s employment with the Company terminates on account of disability, other than any Accrued Compensation and Benefits. For purposes of this Section 5(e), determination of whether the Executive is disabled shall be determined in accordance with the Company’s long term disability plan (if any) and applicable law (if the Company does not have a long term disability plan).

(f)Death. If the Executive’s employment hereunder is terminated by reason of the Executive’s death, the Company shall have no obligation to make payments to the Executive in accordance with the provisions of Section 3 (or otherwise in respect of the Executive’s employment) for periods after the date of the Executive’s death, other than any Accrued Compensation and Benefits.

(g)Duty to Mitigate. If, as of the time of termination of this Agreement, the Executive is indebted to the Company or any of its subsidiaries in any manner whatsoever, evidenced by a written instrument, the Company shall have the right to reduce the amount due to the Executive by such outstanding indebtedness, to the extent consistent with applicable law including without limitation Section 409A of the Code (as later defined); provided, that if, after having reduced the remaining amount due to Executive to zero (or the minimal amount permissible under applicable law), any amount remains due and payable by the Executive to the Company, such amount will remain due to the Company by the Executive.

6. Successors. This Agreement shall be binding on, and inure to the benefit of, the Company and its successors and assigns without further action or consent by the Executive; provided, however, that the Executive hereby agrees to execute an acknowledgement of assignment if requested to do so by the successor, assign or acquiring Person.

The interests of the Executive under this Agreement are not subject to the claims of the Executive’s creditors, other than pursuant to law, and may not otherwise be voluntarily or involuntarily assigned, alienated or encumbered except to the Executive’s estate upon the Executive’s death.

8.Waiver of Breach. The waiver by either the Company or the Executive of a breach of any provision of this Agreement shall not operate as, or be deemed a waiver of, any subsequent breach by either the Company or the Executive.

16.Entire Agreement. This Agreement and the Exhibits attached hereto set forth the entire agreement and understanding between the Company, on the one hand, and the Executive, on the other hand, relating to the subject matter herein and merges all prior discussions between the Parties, including any and all statements made by any officer, director, manager, employee, equity holder or representative of any member of the Company Group or any of their respective Affiliates. The Executive understands and acknowledges that, except as set forth in this Agreement and the agreements referred to herein, (a) no other representation or inducement has been made to the Executive, (b) the Executive has relied on the Executive’s own judgment and investigation in executing this Agreement, and (c) the Executive has not relied on any representation or inducement made by any officer, director, manager, employee, equity holder or representative of any member of the Company Group or any of their respective Affiliates. To the extent there is any conflict between the terms and conditions of this Agreement and the terms and conditions of any prior employment or consulting agreement, the terms and conditions of this Agreement shall control.

17.409A Compliance.

(a)It is intended that this Agreement will comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and any regulations and guideline issued thereunder (“Section 409A”) to the extent that any compensation and benefits provided hereunder constitute deferred compensation subject to Section 409A. This Agreement shall be interpreted on a basis consistent with this intent. The Parties will negotiate in good faith to amend this Agreement as necessary to comply with Section 409A in a manner that preserves the original intent of the Parties to the extent reasonably possible. No action or failure to act, pursuant to this Section 17 shall subject the Company to any claim, liability, or expense, and the Company shall not have any obligation to indemnify or otherwise protect the Executive from the obligation to pay any taxes pursuant to Section 409A.

(b)Notwithstanding anything in this Agreement to the contrary, if any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A would otherwise be payable or distributable under this Agreement by reason of the Executive’s separation from service during a period in which the Executive is a “specified employee” (as defined under Section 409A and the final regulations thereunder), then, subject to any permissible acceleration of payment by the Company under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes):

(i)if the payment or distribution is payable in a lump sum, the Executive’s right to receive payment or distribution of such non-exempt deferred compensation will be delayed until the earlier of the Executive’s death or the first (1st) day of the seventh (7th) month following the Executive’s separation from service; and

(ii)if the payment or distribution is payable over time, the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period

    - 9 -    

|US-DOCS\126616667.2||

immediately following the Executive’s separation from service will be accumulated and the Executive’s right to receive payment or distribution of such accumulated amount will be delayed until the earlier of the Executive’s death or the first (1st) day of the seventh (7th) month following the Executive’s separation from service, whereupon the accumulated amount will be paid or distributed to the Executive and the normal payment or distribution schedule for any remaining payments or distributions will resume.

(c)If and to the extent required to comply with Section 409A, any payment or benefit required to be paid hereunder on account of termination of the Executive’s employment, service (or any other similar term) shall be made only in connection with a “separation from service” with respect to the Executive within the meaning of Section 409A.

(d)Notwithstanding anything herein to the contrary or otherwise, to the extent necessary to avoid taxes and penalties under Section 409A: (i) the amount of expenses eligible for reimbursement or in-kind benefits provided to the Executive during any calendar year will not affect the amount of expenses eligible for reimbursement or in-kind benefits provided to the Executive in any other calendar year; (ii) the reimbursements for expenses for which the Executive is entitled to be reimbursed shall be made on or before the last day of the calendar year following the calendar year in which the applicable expense is incurred; and (iii) the right to payment or reimbursement or in-kind benefits hereunder may not be liquidated or exchanged for any other benefit.

(e)For purposes of Section 409A, the right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments.

(f)Any “nonqualified deferred compensation” subject to Section 409A of the Code payable under this Agreement shall not be subject to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, garnishment by creditors, or borrowing, to the extent necessary to avoid tax, penalties and/or interest under Section 409A of the Code

18.[Intentionally Omitted].

19.Executive’s Compliance with other Agreements. The Executive represents and warrants that (a) the execution of this Agreement by the Executive and the Executive’s performance of the Executive’s obligations hereunder does not constitute (with or without notice or lapse of time or both) a default, breach or violation of any contract, written or oral, express or implied, to which the Executive is a party or to which the Executive is or may be bound, including any contract with any present or former employer, and (b) this Agreement constitutes a valid and legally binding obligation of the Executive, enforceable against the Executive in accordance with its terms, except as such enforcement may be limited by bankruptcy, general principles of equity or other laws affecting creditors or debtors rights generally. All representations and warranties contained herein will survive the execution and delivery of this Agreement.

20.No Rule of Construction. The Parties, each represented by legal counsel in negotiating this Agreement’s terms, have participated jointly in the negotiation of this Agreement and hereby agree that this Agreement shall be construed to be neither against nor in favor of any Party based upon any Party’s role in drafting this Agreement, but rather in accordance with the fair meaning hereof. The Executive hereby acknowledges and agrees that the Executive (a) carefully read and understands all of the provisions of this Agreement and the Schedules and Exhibits attached hereto and thereto, and has had the opportunity for this Agreement and the Schedules and Exhibits attached hereto and thereto to be reviewed by the Executive’s counsel, and (b) is voluntarily entering into this Agreement, including the Schedules and Exhibits attached hereto and thereto. All references in this Agreement to any gender include references to all genders, and references to the singular include references to the plural and vice versa.

RELEASE OF CLAIMS AGREEMENT

This RELEASE OF CLAIMS AGREEMENT (the “Release”) is executed on [_________] [___], 20[__], by and among the undersigned (the “Releasor”), and TOI Management, LLC, a Delaware limited liability company (together with its direct and indirect subsidiaries, the “Company”). All capitalized terms used herein and not otherwise defined herein shall have the meanings given to such term in the Employment Agreement (as defined below).

WITNESSETH:

WHEREAS, the Company and the Releasor are parties to that certain Employment Agreement, dated September 5, 2023 (the “Employment Agreement”);

WHEREAS, pursuant to Section 5(a) and Section 5(b) of the Employment Agreement, the execution and delivery by the Releasor of this Release is a condition precedent to the payment of the Severance Payments; and

WHEREAS, the Releasor has made an independent, voluntary and informed decision that the transactions contemplated by this Release are in the Releasor’s best interests.

NOW, THEREFORE, in consideration of the mutual promises and covenants between the Parties, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and incorporating the recitals set forth above, the Releasor agrees as follows:

1.    Release. The Releasor makes this Release on behalf of the Releasor and the Releasor’s successors, assigns, heirs, beneficiaries, executors, administrators, creditors, representatives, agents and Affiliates (the “Releasing Parties”). The Release is given to the Company and its parents, subsidiaries, Affiliates, partners, and each of their predecessors, successors, and assigns and each and all of their respective past, present or future members, officers, directors, equity holders, trustees, representatives, employees, principals, agents, insurers, partners, lenders, attorneys, and other advisors; and any employee benefit plan established or maintained by the foregoing entities and their plan administrators (collectively, the “Released Parties”). In consideration of the promises and covenants set forth herein and in the Employment Agreement, Releasor hereby fully, finally and irrevocably releases, acquits and forever discharges the Released Parties forever and unconditionally of and from any and all commitments, actions, debts, sums of money, claims, counterclaims, suits, causes of action, damages, penalties, demands, liabilities, obligations, costs, expenses, contracts, covenants, controversies, agreements, promises, judgments and compensation of every kind and nature whatsoever, past, present or future, at law or in equity, whether known or unknown, contingent or otherwise, existing or claimed to exist, which such Releasing Parties, or any of them, had, has or may have had at any time arising from the beginning of time through the date Releasor signs this Release, against the Released Parties, or any of them, including those relating to or arising out of or from the Employment Agreement or the Releasor’s service as an employee, officer and/or director of the Company and the Releasor’s termination of employment thereof (the “Claims”). The Claims include Claims for (a) the payment of Base Salary; Bonus; employee benefits; lost wages or benefits; any other compensation or benefits; compensatory damages; punitive damages; penalties; attorneys’ fees or costs; equitable relief; or any other form of damages or relief; (b) any discrimination claim based on race, religion, color, national origin, age, sex, sexual orientation or preference, disability, or other protected classification under the federal, state, municipal, or local laws of employment, including those arising under the common law, and any alleged violation of the Age Discrimination and Employment Act of 1967 (“ADEA”), the Older Workers Benefit Protection Act, Title VII of the Civil Rights Act of 1964, the Equal Pay Act, the Civil Rights Act of 1991, Americans With Disabilities Act, the Employee Retirement Income Security Act of 1974, the Fair Labor Standards Act, the Family and Medical Leave Act, the Occupational Safety and Health Act, or the Worker Adjustment and Retraining Notification Act, all as amended, and any other law; (c) wrongful termination, back pay, or future wage loss; (d) any other claim, whether in tort, contract or otherwise; and/or (e) any claim for costs, fees or other expenses, including attorneys’ fees. Nothing herein shall be deemed to release the Released Parties or any of them hereunder from and the term “Claim” shall exclude (i) any claims or

    - 2 –[correct pagination]    

DM_US 156368491-1.103640.0013

|US-DOCS\126616667.2||

other rights that either Party may have arising from a breach by the other Party of its obligations set forth in this Release, (ii) any claim, right or remedy of any of the Releasing Parties under, related to, arising out of or in connection with the provisions of the Employment Agreement that survive the termination of the Releasor’s employment, or any of the Released Parties’ obligations under any such agreements in this subsection (ii), (iii) the Company’s obligations to make the Severance Payments set forth in the Employment Agreement or to provide benefits under any other plan of the Company, or (iii) any claims or rights that cannot be waived or released as a matter of law.

2.    Release of Unknown Claims. The Releasor represents that the Releasor is not aware of any claims other than the claims that are released by this Agreement. The Releasor expressly acknowledges and agrees that the releases herein are general in nature and as broad as may be granted under applicable law, and that this Agreement fully and finally settles and forever resolves all of the claims released hereby, even those which are unknown, unanticipated or unsuspected. Upon the advice of legal counsel, the Releasor hereto hereby acknowledges that the Releasor understands, and expressly waives, all benefits and protections under Section 1542 of the Civil Code of California, as well as under any other statutes, legal decisions or common law principles of similar effect to the extent that such benefits or protections may contravene the provisions of this Agreement. Section 1542 of the Civil Code of California states:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.

The Releasor hereto acknowledges that the foregoing waiver was separately bargained for and is a key element and material term of this Agreement.

3.    Representations. Except as set forth on Schedule 1 attached hereto, the Releasor represents and warrants that the Releasor (a) has not filed, and there is not pending with any governmental agency or, any state or federal court, or any other forum, any charge or Claim against any of the Released Parties, and (b) is not aware of any facts that could give rise to a charge or Claim against any of the Released Parties.

4.    No Assignment of Claims. The Releasor hereby represents to the Released Parties that the Releasor (a) is the sole owner of the Claims, (b) has not assigned any Claims or possible Claims against any Released Party, (c) fully intends to release all Claims against the Released Parties, including unknown and contingent Claims, (d) has the full right and power to grant, execute, and deliver the full and complete releases, undertakings, and agreements herein contained, and (e) has consulted with counsel with respect to the execution and delivery of this Release and has been fully apprised of the consequences hereof.

5.    Covenant Not to Sue. The Releasor covenants and agrees not to institute, or to authorize any person on behalf of the Releasor to institute, any action or proceeding against any of the Released Parties with respect to the released Claims. The Releasor understands that nothing contained in this Agreement limits Releasor’s ability to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission, or any other federal, state, or local government agency or commission (collectively, the “Government Agencies”). However, the Releasor also understands that the Releasor is waiving Releasor’s right to recover monetary damages or other individual relief in connection with any such charge, but not Releasor’s right to receive an award pursuant to any whistleblower provisions for information provided to any Government Agencies, consistent with applicable law. The Releasor further understands that this Agreement does not limit Releasor’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company.

|US-DOCS\126616667.2||

6.    Remedies. Subject to Section 7, the Releasor understands and agrees that, if the Releasor violates any of the commitments made in this Release, the Company may seek to recover the Severance Payments and the Releasor agrees to pay the actual attorney’s fees and expenses incurred by the Released Parties in enforcing this Release or in defending a released Claim. However, nothing herein shall affect the Company’s rights to seek restitution, recoupment or setoff or any other remedy in connection with any challenge related to the validity of the release under ADEA.

7.    ADEA Rights. In compliance with the Releasor’s statutorily protected rights under the ADEA, no penalty, condition precedent (including any requirement that the Releasor tender back the Severance Payments) or other limitation shall be imposed if the Releasor challenges the waiver of rights under Section 1 or covenant not to sue pursuant to Section 5 under the ADEA on the grounds that the waiver or covenant not to sue was not made knowingly and voluntarily. This Section 7 shall apply notwithstanding any other provision in the Release. The Releasor hereby acknowledges that the Company has informed the Releasor that the Releasor has up to twenty-one (21) days to sign this Release and the Releasor may knowingly and voluntarily waive all or any part of that twenty-one (21) day period by signing this Release earlier. The Releasor also understands that the Releasor shall have seven (7) days following the date on which the Releasor signs this Release within which to revoke it by providing a written notice of the Releasor’s revocation to the Company at the following address: 18000 Studebaker Rd., STE 800, Cerritos, CA 90703. If this Release is not revoked during that seven (7) day period, it shall become final and binding.

8.    Adequacy of Information. The Releasor hereby represents and warrants that the Releasor has access to adequate information regarding the scope and effect of the release set forth herein, and all other matters encompassed by this Release, to make a voluntary, informed, and knowledgeable decision with regard to entering into this Release. The Releasor further represents and warrants that the Releasor has not relied upon the Company in deciding to enter into this Release and has instead made the Releasor’s own independent analysis and decision to enter into this Release. The Company has advised, and hereby advises, the Releasor to consult an attorney prior to executing this Release which contains a general release and waiver.

9.    Sufficiency of Consideration. The Releasor acknowledges and agrees that the obligations of the Released Parties pursuant to the Employment Agreement and the covenants contained therein provide good and sufficient consideration for every promise, duty, release, obligation, agreement and right contained in this Release.

10.    Law Governing; Dispute Resolution. The Releasor and the Company, each represented by legal counsel in drafting and negotiating this Release, agree that this Release, and all claims and disputes arising in connection with this Release, or the negotiation, breach, termination, performance or validity hereof or the transactions contemplated hereby, shall be governed by and construed in accordance with the laws of the State of California, without giving effect to the conflicts of laws principles thereof. Any claim or dispute arising out of or relating to this Release, or the negotiation, breach, termination, performance or validity hereof or the transactions contemplated hereby, shall be resolved solely and exclusively in accordance with the terms of the Employment Agreement.

11.    Interpretation. Each Party has been represented by counsel in connection with this Release and each provision of this Release shall be interpreted and construed as if it were equally and jointly drafted by the Parties.

12.    Severability. Subject to Section 7, if any term or other provision of this Release is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of law or public policy, the Company may elect to enforce the remainder of the Release or cancel it and seek to recover any consideration paid to the Releasor if the Releasor has violated this Release.

13.    Counterparts and Facsimile Signatures. This Release may be executed in two or more counterparts (including by means of facsimile or electronically transmitted portable document format (.PDF) signature pages), each of which shall be deemed to be an original, but all of which together shall constitute and be one and the same instrument; provided, that facsimile or electronically transmitted

Description of the Business

Description of the Business

Overview of the Business

The Oncology Institute, Inc. (“TOI”) is the successor entity to DFP Healthcare Acquisitions Corp. ("DFPH"). DFPH is a Delaware corporation originally formed in 2019 as a publicly-traded special purpose acquisition company for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination ("Business Combination"). TOI was originally founded in 2007 and is a community oncology practice that operates value-based oncology services platforms. TOI has various wholly-owned subsidiaries, including The Oncology Institute, LLC ("TOI LLC") (which was formerly known as TOI Parent, Inc.), The Oncology Institute of Hope and Innovation Patient Safety Organization, LLC, and TOI Management, LLC (“TOI Management”). Additionally, TOI Management holds master services agreements with affiliated physician-owned professional entities ("TOI PCs") that confer controlling financial interest over the professional entities and their wholly-owned subsidiaries (TOI PCs, together with TOI, the “Company”).

On November 12, 2021 ("Closing Date"), the Business Combination closed following a series of mergers, which resulted in DFPH emerging as the parent of the combined entity Orion Merger Sub II, LLC and the former TOI Parent, Inc. (together, "Legacy TOI"). DFPH was renamed “The Oncology Institute, Inc.” and common stock and "Public Warrants" continued to be listed on Nasdaq under the ticker symbols “TOI” and “TOIIW,” respectively (See Note 16).

Operationally, the Company’s medical centers provide a complete suite of medical oncology services including: physician services, in-house infusion and pharmacy, clinical trials, radiation, educational seminars, support groups, counseling, and 24/7 patient assistance. TOI’s mission is to heal and empower cancer patients through compassion, innovation and state-of-the-art medical care. The Company brings comprehensive, integrated cancer care into the community setting, including clinical trials, palliative care programs, stem cell transplants, and other care delivery models traditionally associated with non-community-based academic and tertiary care settings. In addition, the Company, through its consolidating subsidiary TOI Clinical Research, LLC ("TCR"), performs cancer clinical trials through a network of cancer care specialists. TCR conducts clinical trials for a broad range of pharmaceutical and medical device companies from around the world.

The Company has approximately 112 oncologists and mid-level professionals across 70 clinic locations located within five states: California, Florida, Arizona, Nevada, and Texas. The Oncology Institute CA, a Professional Corporation ("TOI CA"), one of the TOI PCs, has clinic locations in California, Nevada, and Arizona. The Company has contractual relationships with multiple payors, serving Medicare, including Medicare Advantage, Medi-Cal, and commercial patients.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Unaudited Interim Financial Information

The accompanying interim condensed consolidated financial statements are unaudited and have been prepared in accordance with Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and note disclosures required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. However, the Company believes that the disclosures are adequate to ensure the information is not misleading. In the opinion of management, all adjustments (of normal and recurring nature) considered necessary for fair presentation have been reflected in these interim condensed consolidated financial statements. As such, the information included in the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes as of, and for the year ended December 31, 2022, issued on March 16, 2023.

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of TOI, its subsidiaries, all of which are controlled by TOI through majority voting control, and variable interest entities (“VIE”) for which TOI (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation.

Variable Interest Entities

The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and net income from these subsidiaries are included in the consolidated amounts as presented on the Condensed Consolidated Statements of Operations.

The Company holds variable interests in TOI PCs, which it cannot legally own, as a result of entering into master services agreements ("MSAs"). As of September 30, 2023, TOI held variable interests in TOI CA, The Oncology Institute FL, LLC, a Professional Corporation ("TOI FL"), and The Oncology Institute TX, a Professional Corporation ("TOI TX"), all of which are VIEs. The Company is the primary beneficiary of the TOI PCs and thus, consolidates the TOI PCs in its financial statements. As discussed in Note 17, the shareholders of the Company's consolidating VIEs own a minority of the issued and outstanding common shares of the Company.

Business Combinations

The Company accounts for all transactions that represent business combinations using the acquisition method of accounting under Accounting Standards Codification ("ASC") Topic No. 805, Business Combinations (“ASC 805”). The Company first assesses whether an acquisition constitutes a business combination or asset acquisition by applying the screening test and analyzing whether the acquired entity has substantive inputs, processes, and the ability to produce outputs. Upon concluding an acquisition is a business combination, per ASC 805, the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquired entity are recognized and measured at their fair values on the date an entity obtains control of the acquiree. Such fair values that are not finalized for reporting periods following the acquisition date are estimated and recorded as provisional amounts. Adjustments to these provisional amounts during the measurement period (defined as the date through which all information required to identify and measure the consideration transferred, the assets acquired, the liabilities assumed, and the noncontrolling interests obtained, limited to one year from the acquisition date) are recorded when identified. Goodwill is determined as the excess of the fair value of the consideration exchanged in the acquisition over the fair value of the net assets acquired.

The DFPH-Legacy TOI Business Combination was accounted for as a reverse recapitalization. Under this method of accounting, DFPH was treated as the “acquired” company for accounting purposes and the Business Combination was treated as the equivalent of Legacy TOI issuing stock for the net assets of DFPH, accompanied by a recapitalization. The net assets of DFPH are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination were those of TOI LLC.

Segment Reporting

The Company presents the financial statements by segment in accordance with ASC Topic No. 280, Segment Reporting (“ASC 280”) to provide investors with transparency into how the chief operating decision maker (“CODM”) manages the business. The Company determined the CODM is its Chief Executive Officer. The CODM reviews financial information and allocates resources across three operating segments: patient services, dispensary, and clinical trials & other. Each of the operating segments is also a reporting segment as described further in Note 20.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates under different assumptions or conditions. Significant items subject to such estimates and assumptions include judgements related to revenue recognition, estimated accounts receivable and the allowance for credit losses, useful lives and recoverability of long-lived and intangible assets, recoverability of goodwill, fair values of acquired identifiable assets and assumed liabilities in business combinations, fair value of intangible assets and goodwill, fair value of share-based compensation, fair value of liability classified instruments, and judgements related to deferred income taxes.

Net Income (Loss) Per Share

Basic and diluted net income (loss) per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company's Series A Convertible Preferred Stock is classified as a

participating security in accordance with ASC 260. Under the two-class method, basic and diluted net income (loss) per share attributable to common stockholders is computed by dividing the basic and diluted net income (loss) attributable to common stockholders by the basic and diluted weighted-average number of shares of common stock outstanding during the period. Diluted net income per share attributable to common stockholders adjusts basic net income per share for the potentially dilutive impact of stock options, restricted stock units, Medical RSUs (defined in Note 14), earnout shares (defined in Note 14), public warrants, private placement warrants, and Senior Secured Convertible Notes (defined in Note 11).

The treasury stock method is used to calculate the potentially dilutive effect of stock options, RSUs, public warrants, and private placement warrants. The if-converted method is used to calculate the potentially dilutive effect of the Senior Secured Notes. In both methods, diluted net income (loss) attributable to common stockholders and diluted weighted-average shares outstanding are adjusted to account for the impact of the assumed issuance of potential common shares that are dilutive, subject to dilution sequencing rules. The earnout shares are contingently issuable; therefore, the earnout shares are excluded from basic and diluted net income (loss) per share until the market conditions have been met (see more detail on the earnout shares in Note 14). The Medical RSUs (defined in Note 14) are also contingently issuable; therefore, they are excluded from basic net income (loss) per share until the performance and service conditions have been met (see more detail in Note 14). Further, the number of contingently issuable Medical RSUs included in diluted net income (loss) per share is based on the number of shares, if any, that would be issuable if the end of the reporting period were the end of the contingency period and if the result would be dilutive. For the periods presented, the public and private placement warrants are out of the money; therefore, the public and private placement warrants are antidilutive and excluded from diluted net income per share.

Fair Value Measurements

The Company accounts for fair value measurements under ASC Topic No. 820, Fair Value Measurements (“ASC 820”). The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels (see Note 7 for further discussion):

Level 1inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The Company's fair value measurement methodology for cash and cash equivalents, accounts receivable, other receivables, and accounts payable approximates fair value because of the short maturity and high liquidity of these instruments. Fair value measurement of investment securities available for sale is based upon quoted prices from active markets, if available (Level 1). If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation methodologies. Level 2 investment securities include US Treasuries purchased in the secondary market that use pricing inputs other than quoted prices in active markets and fair value is determined using pricing models or other valuation methodologies such as broker price indications, which are based on quoted prices for identical or similar notes, which are Level 2 input measures. Fair value measurements of derivative warrants are based on the market price of our public warrants, which are quoted prices for similar instruments and considered a Level 2 input. Fair value measurements of earnout liabilities are based on the Monte-Carlo Simulation Model, which is considered to be a Level 3 fair value measurement. The primary unobservable input utilized in determining the fair value of the earnouts is the expected volatility of the common stock. Fair value measurements of the convertible note warrant and conversion option derivative liabilities are based on the Black-Derman-Troy model implemented in the Binomial Lattice and Black-Scholes Models, which are considered to be Level 3 fair value measurements. The primary unobservable input utilized in determining the fair value of the convertible note warrant and conversion option derivative liabilities is the expected volatility of the common stock.

Cash and Cash Equivalents

The Company considers all highly liquid investments that are both readily convertible into cash and mature within 90 days from the date of purchase to be cash equivalents.

Accounts Receivable and Allowance for Credit Losses

The Company’s accounts receivables are recorded and stated at the amount expected to be collected determined by each payor, net of an allowance for credit losses, under ASC Topic No. 310, Receivables (“ASC 310”). In accordance with ASC Topic No. 326, Financial Instruments — Credit Losses (“ASC 326”), the Company recognizes credit losses based on a forward-looking current expected credit losses (“CECL”) model. The Company segregates accounts receivables into portfolio segments based on shared risk characteristics, such as line of business and customer type, for evaluation of expected credit losses. The Company makes estimates of expected credit losses based upon its assessment of various factors, including the age of accounts receivable balances, default-based statistics, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The allowance for credit losses is developed using a loss rate method and is recognized in the Condensed Consolidated Statement of Operations. The uncollectible accounts receivables are written off on a quarterly basis in the period when collection activities cease due to a final determination that all or a portion of the balance is no longer collectible and if there is no pending litigation activity related to the receivable. No allowance for credit losses was recorded as of September 30, 2023 and December 31, 2022.

Inventories, net

The Company accounts for inventory under Accounting Standard Codification Topic No. 330, Inventory (“ASC 330”). Inventories consist of intravenous chemotherapy drugs and oral prescription drugs. Inventories are stated at the lower of cost, determined using the weighted average cost method of inventory valuation, or net realizable value. Net realizable value is determined using the selling price, less costs to sell.

The Company receives purchase discounts on products purchased. Contractual arrangements with vendors, including manufacturers and wholesalers, normally provide for the Company to receive purchase discounts from established list prices in one, or a combination, of the following forms: (i) a direct discount at the time of purchase or (ii) a discount for the prompt payment of invoices. Additionally, in other circumstances, the Company may receive rebates when products are purchased indirectly from a manufacturer (e.g., through a wholesaler). These rebates are recognized when intravenous chemotherapy drugs and oral prescription drugs are dispensed and are generally calculated by manufacturers within 30 days after the end of each completed quarter. The Company also receives additional rebates under its wholesaler contracts if it exceeds contractually defined annual purchase volumes. Purchase rebates are recorded as reductions to cost of services.

Goodwill

The Company accounts for goodwill under ASC No. 350, Intangibles - Goodwill and Other (“ASC 350”). Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net assets acquired in our business combinations.

Goodwill is not amortized but is required to be evaluated for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company performs its annual testing of impairment for goodwill in the fourth quarter of each year. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit.

In assessing goodwill for impairment, an entity has the option to assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary. An entity can choose not to perform a qualitative assessment for any of its reporting units and proceed directly to the use of the two-step impairment test.

When assessing goodwill for impairment for the three months ended March 31, 2023, we first performed a qualitative assessment to determine whether it was necessary to perform the two-step quantitative analysis. Based on the qualitative assessment including our share price decrease as well as factors related to macroeconomic conditions, industry and market considerations, cost factors, financial performance and market capitalization, we determined it was likely that our reporting unit fair value was less than its carrying value and the two-step impairment test was performed. Based on the results of our assessment performed there was a goodwill impairment of $16,867 for the three months ended March 31, 2023. There was no impairment of goodwill recorded for the three months ended September 30, 2023. Goodwill impairment recorded for the three and nine months ended September 30, 2023 was $0 and $16,867, respectively.

Debt

The Company accounts for debt net of debt issuance costs and debt discount. Debt issuance costs and debt discount are

capitalized, netted against the related debt for presentation purposes, and amortized to interest expense over the terms of the related debt using the effective interest method.

The Company accounts for bifurcated, debt-classified embedded features separately as derivative liabilities pursuant to ASC Topic No. 815, Derivatives and Hedging ("ASC 815"). Bifurcated, debt-classified embedded features are recorded at fair value on the Company's balance sheet with subsequent changes in fair value recorded in the Condensed Consolidated Statement of Operations each reporting period.

Investments in Marketable Securities

The Company's investments in marketable securities are classified as available-for-sale and are carried at fair value. The Company accounts for its investment securities available for sale using the fair value election pursuant to ASC 825, Financial Instruments ("ASC 825"), where changes in fair value are recorded in unrealized gains (losses), net on the Company's Condensed Consolidated Statements of Operations. The Company determines the appropriate classification of these investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company’s marketable securities are classified as current assets if the maturity date is less than one year from the balance sheet date.

Interest income and accretion on marketable securities are included in interest income in the Condensed Consolidated Statements of Operations. Realized gains and losses on sales of securities, and other-than-temporary declines in the fair value of marketable securities, if any, are included as a component of other income (expense), net in the Condensed Consolidated Statements of Operations. The cost of securities sold is based on the First In, First Out method.

At each reporting period, the Company evaluates available-for-sale marketable securities, to the extent the fair value option is not elected, for any credit-related impairment when the fair value of the investment is less than its amortized cost. If the Company determines that the decline in fair value is below the carrying value and this decline is other-than-temporary, credit-related impairment is recognized in the Consolidated Statement of Operations in accordance with ASC 320, Debt Securities. As of September 30, 2023, there were no available-for-sale instruments for which the fair value option was not elected.

Emerging Growth Company

Pursuant to the Business Combination, the Company qualifies as an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933 ("Securities Act"), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and has elected to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company, nor an emerging growth company which has opted out of using the extended transition period, difficult or impossible because of the potential differences in accounting standards used.

Recently Adopted Accounting Standards

In June 2016, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, instead of when incurred. In November 2018, the FASB issued Accounting Standard Update 2018-19, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2018-19”), which amends Subtopic 326-20 (created by ASU 2016-13) to explicitly state that operating lease receivables are not in the scope of Subtopic 326-20. Additionally, in April 2019, the FASB issued Accounting Standard Update 2019-04, Codification Improvements to Topic 326, Financial Instruments — Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments (“ASU 2019-04”); in May 2019, the FASB issued Accounting Standards Update 2019-05, Financial Instruments — Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”); in November 2019, the FASB issued Accounting Standards Update 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842):

Effective Dates and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2019-10”), and in March 2022, the FASB issued Accounting Standard Update 2022-02, Financial Instruments — Credit Losses: Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”), to provide further clarifications on certain aspects of ASU 2016-13 and to extend the nonpublic entity effective date of ASU 2016-13. The changes (as amended) are effective for the Company for annual and interim periods in fiscal years beginning after December 15, 2022. An entity may early adopt ASU 2016-13, as amended, for annual and interim periods in fiscal years beginning after December 15, 2018. ASU 2016-13 introduced a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including receivables, contract assets and held-to-maturity debt securities, which requires the Company to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 also expands disclosure requirements.

The Company adopted the ASU 2016-13, as amended, effective January 1, 2023, which resulted in changes to the Company’s accounting policies for accounts receivables. Upon adoption of ASU 2016-13, the Company evaluated accounts receivables on a collective (i.e., portfolio) basis when similar risk characteristics were shared. The adoption of this standard did not have a material impact on our consolidated financial statements and there was no allowance for credit losses recorded as of September 30, 2023.

Recently Issued Accounting Standards

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06"), which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU 2020-06 also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. The new standard is effective for the Company beginning January 1, 2024. The Company is currently evaluating the effect of ASU 2020-06 on the Company’s consolidated financial statements and related disclosures.

In October 2021, the FASB issued ASU 2021-08, Business Combinations: Accounting for Contract Assets and Contract Liabilities from Contracts with Customers ("ASU 2021-08"). Under ASU 2021-08, an acquirer must recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contract with Customers (“ASC 606”). The guidance is effective for interim and annual periods beginning after December 15, 2023, with early adoption permitted. The Company will adopt ASU 2021-08 on January 1, 2024 on a prospective basis. The Company does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements and related disclosures.

Risks and Uncertainties [Abstract]

Significant Risks and Uncertainties Including Business and Credit Concentrations

Significant Risks and Uncertainties Including Business and Credit Concentrations

Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, accounts receivable, and investment securities.

Cash accounts in a financial institution may, at times, exceed the Federal Deposit Insurance Corporation coverage of $250 per account ownership category. The Company has not experienced losses on these accounts, and management believes the Company is not exposed to significant risks on such accounts.

The Company’s accounts receivable has implicit collection risk. The Company grants credit without collateral to their patients, most of whom are local residents and are insured under third-party payor agreements. The Company believes this risk is partially mitigated by the Company’s establishment of long-term agreements and relationships with third-party payors that provide the Company with insight into historic collectability and improve the collections process.

The Company's investment securities portfolio is managed by a third party vendor to provide a relatively stable source of investment income from excess liquidity while satisfactorily managing risk, including credit risk, reinvestment risk, liquidity risk, and interest rate risk.

Revenue Concentration Risk

The concentration of net revenue on a percentage basis for major payors for the three and nine months ended September 30, 2023 and 2022 are as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Percentage of Patient Services Net Revenue:
Payor A	11	%	12	%	11	%	14	%
Payor B	14	%	15	%	14	%	16	%

The concentration of gross receivables on a percentage basis for major payors at September 30, 2023 and December 31, 2022 are as follows:

	September 30, 2023		December 31, 2022
Percentage of Gross Receivables of Patient Revenue:
Payor B	10	%	13	%
Payor C	8	%	10	%

All of the Company’s revenue is generated from customers located in the United States.

Vendor Concentration Risk

The concentration of cost of sales on a percentage basis for major vendors for the three and nine months ended September 30, 2023 and 2022 are as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Percentage of Cost of Sales:
Vendor A	100	%	97	%	100	%	69%
Vendor B	N/A		N/A		N/A		29%

The concentration of gross payables on a percentage basis for major payors at September 30, 2023 and December 31, 2022 are as follows:

	September 30, 2023		December 31, 2022
Percentage of Gross Payables:
Vendor A	48	%	66	%
Vendor B	12	%	N/A

Receivables [Abstract]

Accounts Receivable

Accounts Receivable

The Company’s accounts receivable consists primarily of amounts due from third-party payors and patients. See Note 2 for a summary of the Company’s policies relating to accounts receivable and allowance for credit losses.

Accounts Receivable as of September 30, 2023 and December 31, 2022 consist of the following:

(in thousands)	September 30, 2023		December 31, 2022
Oral drug accounts receivable	$	3,238	$	4,165
Capitated accounts receivable	3,187		1,623
FFS accounts receivable	32,388		26,313
Clinical trials accounts receivable	2,488		2,443
Other trade receivables	7,141		5,272
Total	$	48,442	$	39,816

The Company adopted ASU 2016-13, as amended, effective January 1, 2023, and determined no allowance for credit losses was required as of September 30, 2023. No allowance for credit losses was recorded as of September 30, 2023.

During the three and nine months ended September 30, 2023, credit losses related to direct write-offs totaled $31 and $42, respectively.

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

The Company recognizes revenue in accordance with ASC 606 on the basis of its satisfaction of outstanding performance obligations. The Company typically fulfills its performance obligations over time, either over the course of a single treatment (fee-for-service or "FFS"), a month (capitation), or a number of months (clinical research). The Company also has revenue that is satisfied at a point in time (dispensary). See Note 2 for summary of the Company’s policies and significant assumptions related to revenue recognition.

Disaggregation of Revenue

The Company categorizes revenue based on various factors such as the nature of contracts, payors, order to billing arrangements, and cash flows received by the Company, as follows:

(in thousands)	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Patient services
Capitated revenue	$	18,056	$	16,355	$	51,410	$	44,815
FFS revenue	35,578		28,272		105,923		73,978
Subtotal	53,634		44,627		157,333		118,793
Dispensary revenue	26,792		18,839		76,228		57,736

Total	$	82,035	$	64,977	$	238,451	$	181,059

Refer to Note 20 for Segment Reporting for disaggregation of revenue by reporting segment.

Contract Asset and Liabilities

Under ASC 606, contract assets represent rights to payment for performance contingent on something other than the passage of time and accounts receivable are rights to payment for performance without contingencies. The Company does not have any contract assets as of September 30, 2023 and December 31, 2022. Refer to Note 4 for accounts receivable as of September 30, 2023 and December 31, 2022.

Contract liabilities represent cash that has been received for contracts, but for which performance is still unsatisfied. As of September 30, 2023 and December 31, 2022, contract liabilities amounted to $545 and $1,139, respectively. Contract liabilities are included within other current liabilities and presented in Note 9 along with refund liabilities due to materiality.

Remaining Unsatisfied Performance Obligations

The accounting terms for the Company’s patient services and dispensary contracts do not extend past a year in duration. Additionally, the Company applies the ‘as invoiced’ practical expedient to its clinical research contracts.

The Company recorded a net unrealized loss of $157 and a net unrealized loss of $44 for the three and nine months ended September 30, 2023. At September 30, 2023, six securities were in an unrealized loss position. The decline in fair value of our securities since acquisition was attributable to a combination of changes in interest rates and general volatility in the credit market conditions in response to the economic uncertainty caused by the risk of an upcoming recession and monetary policy. The Company does not currently intend to sell any of the securities in an unrealized loss position and further believe, it is more likely than not, that we will not be required to sell these securities before their anticipated recovery.

Accrued interest receivable on cash equivalents and marketable securities was $270 and $274, respectively, at September 30, 2023 and December 31, 2022, and is included within other receivables in the Condensed Consolidated Balance Sheets.

Fair Value Measurements

The following table presents the carrying amounts of the Company’s recurring and non-recurring fair value measurements at September 30, 2023 and December 31, 2022:

	September 30, 2023
(in thousands)	Total		Level 1		Level 2		Level 3
Financial assets:
Marketable securities	$	59,877	$	—	$	59,877	$	—

Contingent consideration liability	1,813		—		1,813		—
Non-recurring fair value measurement:
Goodwill	$	7,230	$	—	$	—	$	7,230

As of September 30, 2023, derivative warrant liabilities of $292 were transferred from a Level 3 to a Level 2 financial instrument as a result of the valuation being based on the market price of our public warrants, which management considers to be a similar and comparable instrument, as compared to the previous valuation which was based on the Binomial Lattice Model.

	December 31, 2022
(in thousands)	Total		Level 1		Level 2		Level 3
Financial assets:
Cash equivalents	$	2,573	$	—	$	2,573	$	—

Conversion option derivative liabilities	3,960		—		—		3,960
Non-recurring fair value measurement:
Goodwill	$	21,418	$	—	$	—	$	21,418

The carrying amounts of cash, accounts receivable, other receivables, and accounts payable approximate fair value because of the short maturity and high liquidity of these instruments.

The Company measures its investments (including cash equivalents, marketable securities, and non-current investments) at fair value on a recurring basis and classifies those instruments within Level 2 of the fair value hierarchy. Investment securities, including U.S. Treasury Bills purchased in the secondary market and U.S. Treasury bonds, are classified within Level 2 of the fair value hierarchy because pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined using models or other valuation methodologies.

The Company measures its private derivative warrants at fair value on a recurring basis and classifies those instruments within Level 2 of the fair value hierarchy because the valuation is based on an observable input of a similar instrument. The Company measures its earnout, convertible note warrant derivative liability, optional redemption derivative liability, conversion option derivative liability, and contingent consideration liability on a recurring basis and classifies those instruments within Level 3 of the fair value hierarchy because unobservable inputs are used to measure fair value. See Note 2 for a summary of the Company’s policies relating to fair value measurements, and Note 11 for more detail on the convertible note warrant, optional redemption, and conversion option derivative liabilities.

The Company measures goodwill at fair value on a nonrecurring basis and classifies goodwill within Level 3 of the fair value hierarchy. It was concluded in connection with the preparation of these financial statements that, based on the results of our most recent qualitative assessment performed for the three months ended September 30, 2023, there was no impairment of goodwill recorded for the three months ended September 30, 2023.

The following table presents information about the Company’s financial liabilities that are measured at fair value on a recurring basis at September 30, 2023:

(in thousands)	Earnout Liability		Conversion Option Derivative Liability
Balance at December 31, 2021	$	60,018	$	—
Conversion option derivative liability acquired (see Note 11 for detail)	—		28,160
Decrease in fair value included in other expense	(59,215)		(24,200)
Balance at December 31, 2022	$	803	$	3,960
Contingent consideration liability acquired (see Note 16 for detail)	$	—	—
Decrease in fair value included in other expense	$	(792)	(2,034)
Balance at September 30, 2023	$	11	$	1,926

As of September 30, 2023, earnout liabilities were valued using a Monte-Carlo Simulation Model, which is considered to be a Level 3 fair value measurement, derivative warrant liabilities were valued using the public warrant trading price, which is

considered to be a Level 2 fair value measurement, and the contingent consideration liability was valued using a present value factor, which is considered to be a Level 2 fair value measurement. As of December 31, 2022, derivative warrant and earnout liabilities were valued using a Binomial Lattice and Monte-Carlo Simulation Model, respectively, which are considered to be Level 3 fair value measurements.

As of September 30, 2023 and December 31, 2022, the convertible note warrant and conversion option derivative liabilities were valued using the Binomial Lattice and Black-Scholes Models, which are considered to be Level 3 fair value measurements. The primary unobservable input utilized in determining the fair value of our Level 3 liabilities is the expected volatility of the common stock. A summary of the inputs used in the valuations is as follows:

	September 30, 2023
	First Tranche Earnout			Second Tranche Earnout			Convertible Note Warrant Derivative Liability			Conversion Option Derivative Liability
Unit price	$	1.40		$	1.40		$	1.40		$	1.40

On August 9, 2022, the Company issued a senior secured convertible note that contains embedded warrant, optional redemption, and conversion option features. Due to the economic disincentive to redeem and the make whole amount that would be required to be paid, it is highly unlikely that the optional redemption would occur, reducing the value during the period to a qualitatively immaterial amount. See Note 11 for additional detail. A summary of the inputs used in the initial measurement of the convertible note warrant and conversion option derivative liabilities is as follows:

	August 9, 2022
	(Initial Measurement)
	Convertible Note Warrant Derivative Liability			Conversion Option Derivative Liability
Unit price	$	6.63		$	6.63
Term (in years)	5.00			5.00
Volatility	42.5		%	42.5		%
Risk-free rate	3.0		%	3.0		%
Dividend yield	—			—
Cost of equity	—			—

Uncertainty of Fair Value Measurement from Use of Significant Unobservable Inputs

The inputs to estimate the fair value of the Company’s earnout, convertible note warrant, and conversion option derivative liabilities were the market price of the Company’s common stock, their remaining expected term, the volatility of the

Company’s common stock price and the risk-free interest rate over the expected term. Significant changes in any of those inputs in isolation can result in a significant change in the fair value measurement.

Generally, an increase in the market price of the Company’s shares of common stock, an increase in the volatility of the Company’s shares of common stock, and an increase in the remaining term of the derivative liabilities would each result in a directionally similar change in the estimated fair value of the Company’s derivative liabilities. Such changes would increase the associated liability while decreases in these assumptions would decrease the associated liability. An increase in the risk-free interest rate would result in a decrease in the estimated fair value measurement and thus a decrease in the associated liability. The Company has not, and does not plan to, declare dividends on its common stock and, as such, there is no change in the estimated fair value of the derivative warrant liabilities due to the dividend assumption.

Leases

The Company leases clinics, office buildings, and certain equipment under noncancellable financing and operating lease agreements that expire at various dates through November 2031. See Note 2 for a summary of the Company’s policies relating to leases.

The initial terms of operating leases range from 1 to 10 years and certain leases provide for free rent periods, periodic rent increases, and renewal options. Monthly payments for these leases range from $0 to $60. All lease agreements generally require the Company to pay maintenance, repairs, property taxes, and insurance costs, which are generally variable amounts based on actual costs incurred during each applicable period.

The Company has determined that periods covered by options to extend the Company's leases are excluded from the lease terms as it is not reasonably certain the Company will exercise such options.

Lease Modifications

During the three months ended September 30, 2023, the Company extended the lease terms of three clinics in California. The extensions constitute a lease modification that qualifies as a change of accounting for the original lease and not a separate contract. Accordingly, for the three months ended September 30, 2023, the Company recognized the difference of $1,274 as an increase to the operating lease liability; net of lease incentives of $1,274, as an increase to operating lease right-of-use asset.

During the nine months ended September 30, 2023, the Company expanded its lease space for one clinic in California and extended the lease terms of five clinics in California. The expansion and extension constitute a lease modification that qualifies as a change of accounting for the original lease and not a separate contract. Accordingly, for the nine months ended September 30, 2023, the Company recognized the difference of $3,018 as an increase to the operating lease liability; net of lease incentives of $3,021, as an increase to operating lease right-of-use asset, and $3 as an increase to rent expense.

The expansion and extension constitute a lease modification that qualifies as a change of accounting for the original lease and not a separate contract. Accordingly, for the nine months ended September 30, 2023, the Company recognized the difference of $3,018 as an increase to the operating lease liability; net of lease incentives of $3,021, as an increase to operating lease right-of-use asset, and $3 as an increase to rent expense.

Senior Secured Convertible Note

On August 9, 2022, TOI entered into a Facility Agreement (the “Facility Agreement”) with certain lenders (“Lenders”) and Deerfield Partners L.P. (“Agent”), pursuant to which, TOI borrowed cash loans from the Lenders in the amount of $110,000, in exchange for which, TOI issued to each Lender a secured convertible promissory note (“Senior Secured Convertible Note”), which is payable to such Lenders in an amount equal to the unpaid principal amount of loans held by such Lender.

The Senior Secured Convertible Note will mature on August 9, 2027 (the “Maturity Date”) and shall bear interest at the rate of 4.00% per annum from August 9, 2022, on the outstanding principal amount, any overdue interest and any other amounts and obligations. The interest shall be paid in cash quarterly in arrears commencing on October 1, 2022. In case of any prepayment, repayment or redemption of the Senior Secured Convertible Note, the Company shall pay any accrued and unpaid interest on the principal, along with a make whole amount and an exit fee.

The Facility Agreement requires the Company to meet certain operational and reporting requirements, including, but not limited to, customary regulatory, financial reporting, and disclosure requirements. Additionally, limitations are placed on the Company's ability to merge with other companies and enter into other debt arrangements and permitted investments are limited to amounts specified in the Facility Agreement. The Facility Agreement also provides certain restrictions on dividend payments and other equity transactions and requires the Company to make prepayments under specified circumstances. Financial covenants in the Facility Agreement require the Company to maintain a minimum unrestricted cash and cash equivalent balance of $40,000 and minimum net quarterly revenues of $50,000 during fiscal year 2023; $75,000 during fiscal year 2024; and $100,000 during fiscal year 2025. Cash Equivalents as defined by the Facility Agreement means (a) any readily-marketable securities (i) issued by, or directly, unconditionally and fully guaranteed or insured by the United States federal government or (ii) issued by any agency of the United States federal government the obligations of which are fully backed by the full faith and credit of the United States federal government, (b) any readily-marketable direct obligations issued by any other agency of the United States federal government, any state of the United States or any political subdivision of any such state or any public instrumentality thereof, in each case having a rating of at least “A-1” from S&P or at least “P-1” from Moody’s, (c) any commercial paper rated at least “A-1” by S&P or “P-1” by Moody’s and issued by any person organized under the laws of any state of the United States, (d) any United States dollar-denominated time deposit, insured certificate of deposit, overnight bank deposit or bankers’ acceptance issued or accepted by any commercial bank that (A) is organized under the laws of the United States, any state thereof or the District of Columbia, (B) is “adequately capitalized” (as defined in the regulations of its primary federal banking regulators) and (C) has Tier 1 capital (as defined in such regulations) in excess of $250,000 and (e) shares of any United States money market fund that (i) has substantially all of its assets invested continuously in the types of investments referred to in clause (a), (b), (c) and/or (d) above with maturities as set forth in the proviso below, (ii) has net assets in excess of $500,000 and (iii) has obtained from either S&P or Moody’s the highest rating obtainable for money market funds in the United States; provided, however, that the maturities of all obligations specified in any of clause (a), (b), (c) and (d) above shall not exceed one year. Additionally, the registration rights agreement between the Company and certain stockholders of Legacy TOI and DFPH entered into in connection with the Business Combination requires the Company to have an effective registration statement and calls for payment should the registration statement cease to remain effective. The Company was in compliance with the covenants of the Facility Agreement as of September 30, 2023.

Conversion Options

The Senior Secured Convertible Note contains several embedded conversion options (the “Conversion Options”) that grant the holders of the Senior Secured Convertible Note the ability to convert the Senior Secured Convertible Note at any time on or after date of issuance of the note. The Conversion Options are convertible into shares of the Company’s common stock (such converted shares, “Conversion Shares”) and, in certain circumstances, a combination of cash and shares of the Company’s common stock, or a combination of cash, other assets and securities or other property of any Company successor entity. The Conversion Shares or settlement amounts shall be computed on the basis of a predefined formula, with a set conversion price of $8.567 as one of the inputs and a conversion cap of 14,663,019 shares. The if-converted value did not exceed the principal amount as of September 30, 2023. No Conversion Shares were issued as of September 30, 2023 and December 31, 2022.

The Company evaluated the Conversion Options of the Senior Secured Convertible Note under ASC 815 and concluded that they require bifurcation from the host contract as a separate unit of account. The Conversion Options do not meet the criteria to be classified in shareholders’ equity and hence, are accounted for as a derivative liability remeasured at fair value at each balance sheet date with changes in fair value reported in earnings.

The Conversion Options contain certain limits on exercise if, after giving effect to the exercise, the Lender would beneficially own a number of shares of common stock of the Company in excess of those permissible under the terms of the Senior Secured Convertible Note. The number of shares to be issued against these notes and conversion price are each subject to adjustments provided under the terms of Senior Secured Convertible Note.

The holder shall receive dividends on the Senior Secured Convertible Note and distributions of any kind made to the holders of common stock, other than dividends of, or distributions in, shares, to the same extent as if the holder had converted the Senior Secured Convertible Note into such shares and had held such shares on the record date for such dividends and distributions any limitations on conversion options.

Optional Redemption

The Facility Agreement also provides the Company the right to redeem the outstanding principal amount of each note (“Optional Redemption”) for the Optional Redemption Price. The Company shall not affect any Optional Redemption under this Senior Secured Convertible Note unless along with this, the Company effects an optional redemption under all other notes in accordance with the terms thereof, on a pro rata basis, based upon the respective applicable original principal amount of each of the notes outstanding as of the date the notice for Optional Redemption is delivered to the holders.

The Company evaluated the Optional Redemption feature of the Senior Secured Convertible Note under ASC 815 and concluded that it requires bifurcation from the host contract as a separate unit of account. The Optional Redemption feature does not meet the criteria to be classified in shareholders’ equity and hence, is accounted for as a derivative liability remeasured at fair value at each balance sheet date with changes in fair value reported in earnings. The fair value of the Optional Redemption feature is de minimis.

If the principal redemption amount specified in an Optional Redemption notice is less than the entire principal amount then outstanding, the principal amount specified in each conversion notice shall be applied (i) first, to reduce, on a dollar-for-dollar basis, the principal amount of the note in excess of the principal redemption amount until such excess principal amount is reduced to zero and (ii) to reduce, on a dollar-for-dollar basis, the principal redemption amount until all of such principal redemption amount shall have been converted.

Convertible Note Warrants

The Facility Agreement also provides for the issuance of warrants (the “Convertible Note Warrants”) on each date any principal amount of any Senior Secured Convertible Note is paid, repaid, redeemed, or prepaid at any time prior to the Maturity Date. Convertible Note Warrants are exercisable from their original issue date to August 9, 2027, for purchase of an aggregate amount of Conversion Shares into which such principal amount of Senior Secured Convertible Note was convertible into, immediately prior to such payment, at an exercise price of $8.567. The holder of Convertible Note Warrants may pay the exercise price in cash or exercise the warrant on cashless basis or through a reduction of an amount of principal outstanding under any Senior Secured Convertible Note held by such holder. In the event that the Convertible Note Warrant has not been exercised in full as of the last business day during its term, the holder shall be deemed to have exercised the purchase rights represented by the Convertible Note Warrant in full as a cashless exercise, in which event the Company shall issue number of shares to the holder computed on the basis of a predefined formula.

The Company evaluated the Convertible Note Warrants of the Senior Secured Convertible Note under ASC 815 and concluded that they require bifurcation from the host contract as a separate unit of account. The Convertible Note Warrants do not meet the criteria to be classified in shareholders’ equity and hence, are accounted for as a derivative liability remeasured at fair value at each balance sheet date with changes in fair value reported in earnings.

The Convertible Note Warrant holder shall be entitled to receive any dividend or distribution made by the Company to the holders of common stock to the same extent as if the holder had exercised the Convertible Note Warrants in full in a cash exercise.

The number of shares to be issued against these warrants and exercise price are each subject to adjustments provided under the terms of Convertible Note Warrants. The Convertible Note Warrants contain certain limits on exercise if, after giving effect to the exercise, the Lender would beneficially own a number of shares of common stock of the Company in excess of those permissible under the terms of the Convertible Note Warrants. Further, the Convertible Note Warrants can be fully or partially settled in cash in certain cases in accordance with the terms of issuance such as when shares issuable upon exercise of the warrants exceed a predefined number, upon occurrence of predefined event of default and upon occurrence of predefined events that will bring a fundamental change in the Company such as merger, consolidation, business combination, recapitalization, reorganization, reclassification or other similar event.

As of September 30, 2023 and December 31, 2022, there were no Convertible Note Warrants outstanding.

Allocation of Proceeds

The Company has allocated total issuance proceeds of $110,000 among the Senior Secured Convertible Note and Convertible Note Warrants based on fair value. Upon issuance of the Convertible Note Warrants, the Company recorded Convertible Note Warrants, Optional Redemption, and Conversion Options of $0, $0 and $28,160, which were recorded as a debt discount to the Senior Secured Convertible Note of $110,000. The Company will amortize the debt discount over a period of 5 years (of which 3.86 years remain).

The total issuance costs of $4,924 was allocated among the Senior Secured Convertible Note, Convertible Note Warrants, Optional Redemption, and Conversion Options, by allocating costs of $0, $0, and $1,261 to the Convertible Note Warrants, Optional Redemption, and Conversion Options with the residual cost of $3,663 being allocated to the Senior Secured Convertible Note (in addition to the debt discount). The Company expensed issuance costs allocated to Warrants, Optional Redemption, and Conversion Options at inception and will amortize the costs allocated to the Senior Secured Convertible Note over a period of 5 years (of which 3.86 years remain).

Amounts Outstanding and Recognized during the Periods Presented

The Senior Secured Convertible Note as of September 30, 2023 and December 31, 2022 consists of the following:

The Company recorded interest of $1,125 and $3,337 on the Credit Agreement term loan for the three and nine months ended September 30, 2023, respectively. There was $892 of debt issuance cost and debt discount amortization included in interest expense, $648 of recorded interest related to this facility for the three and nine months ended September 30, 2022.

On August 9, 2022, the Company also entered into the Guarantee and Security Agreement (“Guarantee Agreement”) with the Agent for the purpose of providing a guarantee of all the obligations under the Facility Agreement (refer to Note 15. Commitments and Contingencies for detail).

Income Taxes

Income Taxes

The Company recorded income tax expense of $135 and $278 for the three and nine months ended September 30, 2023, respectively, as compared to income tax benefit of $24 and income tax expense of $124 for the three and nine months ended September 30, 2022, respectively. The increase of $159, in income tax expense for the three months ended September 30, 2023 as compared to the three months ended September 30, 2022, is primarily related to the corresponding increase in the valuation allowance for TOI. The Company's effective tax rate decreased to (0.43)% for the nine months ended September 30, 2023, from 1.10% for the nine months ended September 30, 2022.

The Company's effective tax rate for the nine months ended September 30, 2023, was different than the U.S. federal statutory tax rate of 21.00%, primarily due to the increased valuation allowance, partially offset by the tax effect of the change in fair market value of the warrant, earn out, and derivative liabilities, as well as the Section 162(m) limitation on compensation for covered employees and Section 163(l) limitation on interest expense related to the convertible note, which are non-deductible for federal income tax purposes.

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

Non-Qualified Stock Option Plan

On January 2, 2019, the Company issued and adopted the 2019 Non-Qualified Stock Option Plan (the “2019 Plan”) to incentivize directors, consultants, advisors, and other key employees of the Company and its subsidiaries to continue their association by providing opportunities to participate in the ownership and further growth of the Company. The 2019 Plan provides for the grant of options (the “Stock Options”) to acquire common shares of the Company.

Stock Options are exercised from the pool of shares designated by the appropriate Committee of the Board of Directors. The grant-date fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The grant date fair value of the service vesting and the performance vesting options is recognized as an expense over the requisite service period and upon the achievement of the performance condition deemed probable of being achieved, respectively. The exercise price of each Stock Option shall be determined by the Committee and may not be less than the fair market value of the common shares on the date of grant. Stock Options have 10-year terms, after which they expire and are no longer exercisable.

The total number of common shares for which Stock Options may be granted under the 2019 Plan shall not exceed 13,640. The 2019 Plan was amended on November 6, 2020, pursuant to which the total number of common shares for which Stock Options may be granted under the 2019 Plan shall not exceed 15,640.

Stock Options become vested upon fulfillment of either service vesting conditions, performance vesting conditions, or both, as determined by the award agreement entered into by the Company and optionee. The service vesting requirement states that: (i) 25% of the service vesting options shall vest on the first anniversary of the grant date and (ii) the remaining 75% shall vest on an equal monthly-basis, so long as the optionee has remained continuously employed by the Company from the date of the award through the fourth anniversary of the grant date. The performance vesting requirement states that Stock Options shall vest upon sale of the Company only if the optionee has been continuously employed by the Company or its subsidiaries from the grant date through the date of such sale of the Company. For the awards vesting based on service conditions only and that have a graded vesting schedule, the Company recognizes compensation expense for vested awards in earnings, net of actual forfeitures in the period they occur, on a straight-line basis over the requisite service period.

Conversion of the Stock Options

In conjunction with the Business Combination, the Company amended and fully restated the 2019 Plan through the establishment of the 2021 Incentive Plan (“2021 Plan”). Pursuant to the 2021 Plan, each remaining legacy Stock Option from the 2019 Plan that was outstanding immediately prior to the Business Combination, whether vested or unvested, was converted into an option to purchase a number of shares of common stock (each such option, an “Exchanged Option”) equal to the product (rounded down to the nearest whole number) of (i) the number of shares of Legacy TOI stockholders subject to such Stock Option immediately prior to the Business Combination, and (ii) an exercise price per share equal to (A) the exercise price per

share of such Stock Option immediately prior to the consummation of the Business Combination, divided by (B) the Common Stock Exchange Ratio ("Stock Option Exchange Ratio"). Following the Business Combination, each Exchanged Option that was previously subject to time vesting only, will continue to be governed by the same terms and conditions (including vesting and exercisability terms) as were applicable to the corresponding former old Stock Option immediately prior to the consummation of the Business Combination. Each Exchanged Option that was previously subject to performance vesting, will no longer be subject to the sale of the Company, and was modified to include service requirements only, under which, the Exchange Options will vest on a monthly-basis, so long as the optionee has remained continuously employed by the Company from the date of the Business Combination through the third anniversary of the Closing Date. The Company treated the Exchanged Options that were previously subject to performance conditions as a new award granted at the Closing Date. The Exchanged Options that were previously subject to service vesting only were not modified as a result of the Business Combination. All stock option activity was retroactively restated to reflect the Exchanged Options.

As of the Closing Date, the 11,850 Stock Options outstanding under the 2019 Plan were converted into 6,925,219 Exchanged Options after effect of the Common Stock Exchange Ratio. This effect of the Common Stock Exchange Ratio has been retroactively adjusted throughout the Company's condensed consolidated financial statements.

As of September 30, 2023, the total number of shares of common stock remaining available for future awards (e.g., non-qualified stock options, incentive stock options, restricted stock units, restricted stock awards) under the 2021 Plan is 6,782,851.

The weighted average assumptions used in the Black-Scholes-Merton option-pricing model for the units granted during the nine months ended September 30, 2023 and 2022 Stock Options are provided in the following table:

	September 30, 2023	September 30, 2022
Valuation assumptions:
Expected dividend yield	—%	—%
Expected volatility	64.00%	35.0% to 45.0%
Risk-free rate	3.40%	2.33% to 2.84%
Expected term (years)	6.25	6.07 to 6.65

The Company used the simplified method to calculate the expected term of stock option grants because sufficient historical exercise data was not available to provide a reasonable basis for the expected term. Under the simplified method, the expected term is estimated to be the mid-point between the vesting date and the contractual term of the option.

Stock option activity during the nine months ended September 30, 2023 and 2022 is as follows:

Stock options	Number of shares	Weighted average exercise price		Weighted average remaining contractual term	Aggregate intrinsic value (in thousands)
Balance at January 1, 2023	8,049,474	$	2.14

Vested Options Exercisable at September 30, 2022	2,762,097	$	0.87	6.74	$	10,391

Total share-based compensation expense relating to stock options during the three and nine months ended September 30, 2023 was $2,563 and $7,823, respectively. Total share-based compensation expense relating to stock options during the three and nine months ended September 30, 2022 was $2,756 and $8,837, respectively.

At September 30, 2023, there was $13,279 of total unrecognized compensation cost related to unvested service Stock Options granted under the 2021 Plan and 2019 Plan that are expected to vest. That cost is expected to be recognized over a weighted average period of 2.56 years as of September 30, 2023. The total fair value of common shares vested during the nine months ended September 30, 2023 and 2022 was $1,616 and $6,976, respectively.

Restricted Stock Awards (“RSAs”) and Restricted Stock Units (“RSUs”)

Agajanian Holdings (“Holdings”), a holder of Series A Preferred Shares of Legacy TOI, entered into arrangements with physicians employed by the TOI PCs to issue RSAs which represent Series A Preferred Shares of Legacy TOI. The Legacy TOI RSAs only have performance vesting requirements linked to the sale of the Company so long as the grantee remains continuously and actively employed by the Company’s subsidiaries through the vesting date.

Conversion of the RSAs

Each of the Legacy TOI RSAs, from the Plan that was outstanding immediately prior to the Business Combination, whether vested or unvested, was converted into an RSU equal to the product (rounded down to the nearest whole number) of (i) the number of shares of RSAs immediately prior to the Business Combination, (ii) conversion rate of 1:10 of the Series A Preferred Shares of Legacy TOI, and (iii) the Common Stock Exchange Ratio. Following the Business Combination, each RSU is no longer subject to the sale of the Company event in order to vest, but was modified to include service requirements only. The service vesting requirement states that: (i) 16.67% of the RSUs shall vest on the sixth month anniversary of the Closing Date, and (ii) the remaining 83.33% shall vest on an equal quarterly-basis, so long as the grantee has remained continuously employed by the Company from the date of the award through the third anniversary of the grant date. The Company treated the RSUs that were previously subject to performance conditions as a new award granted at the Closing Date. All RSAs activity was retroactively restated to reflect the RSUs.

As of the Closing Date, the 2,210 RSAs outstanding under the Plan were converted into 1,291,492 RSUs upon the completion of the Business Combination after giving effect to the Common Stock Exchange Ratio. This effect of the Common Stock Exchange Ratio has been retroactively adjusted throughout our condensed consolidated financial statements.

The weighted-average grant date fair values of the RSUs granted during nine months ended September 30, 2023 and 2022, were determined to be $0.64 and $6.82, respectively, based on the fair value of the Company’s common share at the grant date.

A summary of the activity for the RSUs for the nine months ended September 30, 2023 and 2022, respectively, are shown in the following table:

	Nine Months Ended September 30,
	2023			2022
	Number of Shares	Weighted Average Grant Date Fair Value		Number of Shares	Weighted Average Grant Date Fair Value

The total share-based compensation expense related to RSUs during the three and nine months ended September 30, 2023 was $1,188 and $4,715, respectively and during the three and nine months ended September 30 , 2022 was $2,356 and $5,848, respectively.

As of September 30, 2023 there was $9,033 of unrecognized compensation expense related to the RSUs that are expected to vest. That cost is expected to be recognized over a weighted average period of 2.56 years as of September 30, 2023. As of September 30, 2023, 2,024,351 of the RSUs have vested and zero were net settled to cover the required withholding tax upon vesting.

RSUs granted to Medical Employees and Nonemployees

In 2022, the Company entered into arrangements with certain medical directors and supervisors of advanced practice providers employed by or engaged as independent contractors of TOI to issue RSUs of the Company (“Medical RSUs”). Vesting on each annual Medical RSU award is dependent on the participant performing a specified minimum number of service hours during the calendar year (“One-Year Term”) and further contingent upon the participant’s continued service to, or employment by, the Company through the grant date. The Company’s regular grant date for these Medical RSU awards is in the first quarter of the calendar year following the one-Year Term.

The number of Medical RSUs granted to each such participant is determined by dividing a fixed monetary value by the trailing five-day closing price per share of the Common Stock preceding the grant date. Due to the calculation, some Medical RSU awards are liability-classified whereas other Medical RSU awards have a fixed number of shares and are equity-classified.

In the fourth quarter of 2022, the Company amended the terms of Medical RSUs previously issued to approximately 21 participants during the first quarter of 2022. The amendment primarily updated the vesting period and conditions. The original terms of the Medical RSU awards were deemed improbable of vesting at the modification date whereas the amended Medical RSU awards were deemed probable of vesting at the modification date, and thus are a Type III modification under ASC 718. The modification to the Medical RSUs resulted in $187 incremental share-based compensation expense before forfeitures, $(11) after accounting for forfeitures related to participants who did not perform the minimum number of service hours specified, recorded in the Company's Statement of Operations.

The total fair value of the liability-classified Medical RSU awards granted in 2022 and outstanding as of December 31, 2022 was approximately $264, which represents the fixed monetary value of the awards. The weighted-average grant-date fair value, based on the Company’s share price granted during 2023 and 2022 was $1.00 and $3.56 for equity-classified Medical RSUs granted. There were no unvested equity-classified Medical RSU awards outstanding as of September 30, 2023.

A summary of the activity for the equity-classified Medical RSUs for the nine months ended September 30, 2023 is shown in the following table:

	Nine Months Ended
	September 30, 2023
Balance at beginning of period	147,470
Granted	824,288
Vested	(971,758)
Forfeited	—
Balance at end of period	—

Total compensation costs for Medical RSUs was $814 and $872 for the three and nine months ended September 30, 2023. As of September 30, 2023, all Medical RSUs have vested.

Earnout Shares granted to Employees

As part of the Business Combination, DFPH issued to eligible Legacy TOI stockholders and Legacy TOI employees the contingent right to receive up to $12.5 million additional shares of common stock (“Legacy TOI Earnout Shares”), in two tranches of $5.0 million ("First Earnout Tranche") and $7.5 million ("Second Earnout Tranche"), respectively, upon the Company common stock achieving a price per share of $12.50 during the two-year period following the Closing or a price per share of $15.00 during the three-year period following the Closing Date, in each case, as its last reported sales price per share for any 20 trading days within any 30 consecutive trading day period within the applicable period ("Earnout Terms"); provided, that (i) if one or both of the share price triggers has not been achieved prior to the end of the three-year period following the Closing Date, (ii) the Company enters into a definitive agreement that would result in a change of control and (iii) the price per share of the Company’s common stock in such transaction is equal to or greater than one or both of the share price triggers, then at the Closing Date of such transaction, the Company shall issue the applicable portion of the Legacy TOI Earnout Shares as if such share price trigger had been achieved.

In addition, certain DFPH common stockholders deposited 575,000 shares of DFPH common stock in an escrow account that will vest and be released to such holders in two tranches of 50%, each (“DFPH Earnout Shares”), upon the Company common stock achieving the Earnout Terms as described above; provided, that (i) if one or both of the share price triggers has not been achieved prior to the end of the three-year period following the closing, (ii) the Company enters into a definitive agreement that would result in a change of control and (iii) the price per share of common stock in such transaction is equal to or greater than one or both of the share price triggers, then at the closing of such transaction, the Company shall issue the applicable portion of the DFPH Earnout Shares as if such share price trigger had been achieved. To the extent any DFPH Earnout Shares remain unvested at the expiration of the three-year period following the closing, such DFPH Earnout Shares shall be forfeited and cancelled without any consideration.

Collectively, the Legacy TOI Earnout Shares and DFPH Earnout Shares constitute the “Earnout Shares”, the “Earnout”, and the “Earnout Liability”.

The Company issued Legacy TOI Earnout Shares to Legacy TOI option holders and Legacy RSU holders (“Option-holders Earnout” and “RSU-holders Earnout”, respectively, together “Employees Earnout Shares”).

The Option-holders Earnout vests upon the Company common stock achieving the price per share as provided above, so long as the optionee has remained continuously employed by the Company at that date. The RSU-holders Earnout vests upon (a) the Company common stock achieving the price per share as provided above, and (b) the underlying RSU vested, so long as the optionee has remained continuously employed by the Company at that date.

The grant date fair value of the First Earnout Tranche and Second Earnout Tranche as of Closing Date was determined to be $8.35 and $6.76, respectively. The assumptions used in the Monte-Carlo Simulation model for the Earnout Shares granted on the Closing Date are provided in the following table:

As of September 30, 2023, there was $183 of unrecognized compensation expense related to the Employees Earnout Shares, which are expected to vest. That cost is expected to be recognized over a weighted average period of 0.37 years as of September 30, 2023. As of September 30, 2023, none of the Employee Earnout Shares have vested.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

The Company evaluates contingencies based upon available evidence. In addition, allowances for losses are provided each year for disputed items which have continuing significance. The Company believes that allowances for losses have been provided to the extent necessary, and that its assessment of contingencies is reasonable. Due to the inherent uncertainties and subjectivity involved in accounting for contingencies, there is at least a reasonable possibility that recorded estimates will change by a material amount in the near term. To the extent that the resolution of contingencies results in amounts which vary from management’s estimates, future operating results will be charged or credited. The principal commitments and contingencies are described below.

Legal Matters

The Company is subject to certain outside claims and litigation arising in the ordinary course of business. In the opinion of Management, the outcome of such matters will not have a material effect on the Company’s condensed consolidated financial statements. Loss contingencies entail uncertainty and a possibility of loss to an entity. If the loss is probable and the amount of loss can be reasonably estimated, the loss should be accrued according to ASC No. 450-20, Disclosure of Certain Loss Contingencies.

Indemnities

The Company’s Articles of Incorporation and bylaws require it, among other things, to indemnify the director or officer against specified expenses and liabilities, such as attorneys’ fees, judgments, fines, and settlements, paid by the individual in connection with any action, suit, or proceeding arising out of the individual’s status or service as its director or officer, other than liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest, and to advance expenses incurred by the individual in connection with any proceeding against the individual with respect to which the individual may be entitled to indemnification by the Company. The Company also indemnifies its lessor in connection with its facility lease for certain claims arising from the use of the facilities. These indemnities do not provide for any limitation of the maximum potential future payments it could be obligated to make. Historically, the Company has not incurred any payments for these obligations and, therefore, no liabilities have been recorded for these indemnities in the accompanying Condensed Consolidated Balance Sheets.

The Health Insurance Portability and Accountability Act

The Health Insurance Portability and Accountability Act (“HIPAA”) assures health insurance portability, reduces healthcare fraud and abuse, guarantees security and privacy of health information, and enforces standards for health information. Organizations are required to be in compliance with HIPAA provisions. The Health Information Technology for Economic and Clinical Health Act (“HITECH”) imposes notification requirements in the event of certain security breaches relating to protected health information. Organizations are subject to significant fines and penalties if found not to be compliant with the provisions outlined in the regulations. The Company believes it is in compliance with these laws.

Regulatory Matters

Laws and regulations governing the Medicare program and healthcare generally, are complex and subject to interpretation. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing. While no regulatory inquiries have been made, compliance with such laws and regulations can be subject to future government review and interpretation as well as significant regulatory action including fines, penalties, and exclusion from the Medicare and Medi-Cal programs.

Many of the Company’s payor and provider contracts are complex in nature and may be subject to differing interpretations regarding amounts due for the provision of medical services. Such differing interpretations may not come to light until a substantial period of time has passed following contract implementation. Liabilities for claims disputes are recorded when the loss is probable and can be estimated. Any adjustments to reserves are reflected in current operations. The Company does not have any reserves for regulatory matters as of September 30, 2023 and December 31, 2022.

Liability Insurance

The Company believes that its insurance coverage is appropriate based upon the Company’s claims experience and the nature and risks of the Company’s business. In addition to the known incidents that have resulted in the assertion of claims, the Company cannot be certain that its insurance coverage will be adequate to cover liabilities, arising out of claims asserted against the Company or the Company’s affiliated professional organizations, in the future where the outcomes of such claims are unfavorable.

The Company believes that the ultimate resolution of all pending claims, including liabilities in excess of the Company’s insurance coverage, will not have a material adverse effect on the Company’s financial position, results of operations or cash flows; however, there can be no assurance that future claims will not have such a material adverse effect on the Company’s business. Contracted physicians are required to obtain their own insurance coverage.

Guarantees

The Company, along with certain of the Company's subsidiaries from time to time party to the Facility Agreement (“Guarantors”), have pledged a first priority perfected lien on substantially all of their respective personal and real property, as collateral security for the payment of outstanding obligations, under the Facility Agreement.

Any changes in the fair value of the deferred cash consideration liability will be recognized in the Statements of Operations.

Summary of Consideration Transferred

Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Such assets include synergies the Company expects to achieve, such as the use of the Company's existing infrastructure to support the added membership, and future economic benefits arising from the assembled workforce. The purchase consideration for the acquisitions has been allocated under the acquisition method of accounting to the estimated fair market value of the net assets acquired including a residual amount of tax deductible goodwill as noted in the fair value table below.

Acquisition costs amounted to $41 and $166 for the three months ended September 30, 2023 and 2022 respectively, and $112 and $700 for the nine months ended September 30, 2023 and 2022 respectively, were recorded as “General and administrative expenses” in the accompanying Condensed Consolidated Statements of Operations.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2023

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of TOI, its subsidiaries, all of which are controlled by TOI through majority voting control, and variable interest entities (“VIE”) for which TOI (through TOI Management) is the primary beneficiary. The Company consolidates entities in which it has a controlling financial interest based on either the variable interest entity or voting interest model. All significant intercompany balances and transactions have been eliminated in consolidation.

Variable Interest Entities

Variable Interest Entities

The Company consolidates entities for which it has a variable interest and is determined to be the primary beneficiary. Noncontrolling interests in less-than-wholly-owned consolidated subsidiaries of the Company are presented as a component of total equity to distinguish between the interests of the Company and the interests of the noncontrolling owners. Revenues, expenses, and net income from these subsidiaries are included in the consolidated amounts as presented on the Condensed Consolidated Statements of Operations.

The Company holds variable interests in TOI PCs, which it cannot legally own, as a result of entering into master services agreements ("MSAs"). As of September 30, 2023, TOI held variable interests in TOI CA, The Oncology Institute FL, LLC, a Professional Corporation ("TOI FL"), and The Oncology Institute TX, a Professional Corporation ("TOI TX"), all of which are VIEs. The Company is the primary beneficiary of the TOI PCs and thus, consolidates the TOI PCs in its financial statements.

Business Combinations

Business Combinations

The Company accounts for all transactions that represent business combinations using the acquisition method of accounting under Accounting Standards Codification ("ASC") Topic No. 805, Business Combinations (“ASC 805”). The Company first assesses whether an acquisition constitutes a business combination or asset acquisition by applying the screening test and analyzing whether the acquired entity has substantive inputs, processes, and the ability to produce outputs. Upon concluding an acquisition is a business combination, per ASC 805, the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquired entity are recognized and measured at their fair values on the date an entity obtains control of the acquiree. Such fair values that are not finalized for reporting periods following the acquisition date are estimated and recorded as provisional amounts. Adjustments to these provisional amounts during the measurement period (defined as the date through which all information required to identify and measure the consideration transferred, the assets acquired, the liabilities assumed, and the noncontrolling interests obtained, limited to one year from the acquisition date) are recorded when identified. Goodwill is determined as the excess of the fair value of the consideration exchanged in the acquisition over the fair value of the net assets acquired.

The DFPH-Legacy TOI Business Combination was accounted for as a reverse recapitalization. Under this method of accounting, DFPH was treated as the “acquired” company for accounting purposes and the Business Combination was treated as the equivalent of Legacy TOI issuing stock for the net assets of DFPH, accompanied by a recapitalization. The net assets of DFPH are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination were those of TOI LLC.

Segment Reporting

Segment Reporting

The Company presents the financial statements by segment in accordance with ASC Topic No. 280, Segment Reporting (“ASC 280”) to provide investors with transparency into how the chief operating decision maker (“CODM”) manages the business. The Company determined the CODM is its Chief Executive Officer. The CODM reviews financial information and allocates resources across three operating segments: patient services, dispensary, and clinical trials & other. Each of the operating segments is also a reporting segment as described further in Note 20.

Use of Estimates

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates under different assumptions or conditions. Significant items subject to such estimates and assumptions include judgements related to revenue recognition, estimated accounts receivable and the allowance for credit losses, useful lives and recoverability of long-lived and intangible assets, recoverability of goodwill, fair values of acquired identifiable assets and assumed liabilities in business combinations, fair value of intangible assets and goodwill, fair value of share-based compensation, fair value of liability classified instruments, and judgements related to deferred income taxes.

Net Income (Loss) Per Share

Net Income (Loss) Per Share

Basic and diluted net income (loss) per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company's Series A Convertible Preferred Stock is classified as a

participating security in accordance with ASC 260. Under the two-class method, basic and diluted net income (loss) per share attributable to common stockholders is computed by dividing the basic and diluted net income (loss) attributable to common stockholders by the basic and diluted weighted-average number of shares of common stock outstanding during the period. Diluted net income per share attributable to common stockholders adjusts basic net income per share for the potentially dilutive impact of stock options, restricted stock units, Medical RSUs (defined in Note 14), earnout shares (defined in Note 14), public warrants, private placement warrants, and Senior Secured Convertible Notes (defined in Note 11).

The treasury stock method is used to calculate the potentially dilutive effect of stock options, RSUs, public warrants, and private placement warrants. The if-converted method is used to calculate the potentially dilutive effect of the Senior Secured Notes. In both methods, diluted net income (loss) attributable to common stockholders and diluted weighted-average shares outstanding are adjusted to account for the impact of the assumed issuance of potential common shares that are dilutive, subject to dilution sequencing rules. The earnout shares are contingently issuable; therefore, the earnout shares are excluded from basic and diluted net income (loss) per share until the market conditions have been met (see more detail on the earnout shares in Note 14). The Medical RSUs (defined in Note 14) are also contingently issuable; therefore, they are excluded from basic net income (loss) per share until the performance and service conditions have been met (see more detail in Note 14). Further, the number of contingently issuable Medical RSUs included in diluted net income (loss) per share is based on the number of shares, if any, that would be issuable if the end of the reporting period were the end of the contingency period and if the result would be dilutive. For the periods presented, the public and private placement warrants are out of the money; therefore, the public and private placement warrants are antidilutive and excluded from diluted net income per share.

Fair Value Measurements

Fair Value Measurements

The Company accounts for fair value measurements under ASC Topic No. 820, Fair Value Measurements (“ASC 820”). The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels (see Note 7 for further discussion):

Level 1inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The Company's fair value measurement methodology for cash and cash equivalents, accounts receivable, other receivables, and accounts payable approximates fair value because of the short maturity and high liquidity of these instruments. Fair value measurement of investment securities available for sale is based upon quoted prices from active markets, if available (Level 1). If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation methodologies. Level 2 investment securities include US Treasuries purchased in the secondary market that use pricing inputs other than quoted prices in active markets and fair value is determined using pricing models or other valuation methodologies such as broker price indications, which are based on quoted prices for identical or similar notes, which are Level 2 input measures. Fair value measurements of derivative warrants are based on the market price of our public warrants, which are quoted prices for similar instruments and considered a Level 2 input. Fair value measurements of earnout liabilities are based on the Monte-Carlo Simulation Model, which is considered to be a Level 3 fair value measurement. The primary unobservable input utilized in determining the fair value of the earnouts is the expected volatility of the common stock. Fair value measurements of the convertible note warrant and conversion option derivative liabilities are based on the Black-Derman-Troy model implemented in the Binomial Lattice and Black-Scholes Models, which are considered to be Level 3 fair value measurements. The primary unobservable input utilized in determining the fair value of the convertible note warrant and conversion option derivative liabilities is the expected volatility of the common stock.

Cash and Cash Equivalents

Cash and Cash EquivalentsThe Company considers all highly liquid investments that are both readily convertible into cash and mature within 90 days from the date of purchase to be cash equivalents.

Accounts Receivable and Allowance for Credit Losses

Accounts Receivable and Allowance for Credit LossesThe Company’s accounts receivables are recorded and stated at the amount expected to be collected determined by each payor, net of an allowance for credit losses, under ASC Topic No. 310, Receivables (“ASC 310”). In accordance with ASC Topic No. 326, Financial Instruments — Credit Losses (“ASC 326”), the Company recognizes credit losses based on a forward-looking current expected credit losses (“CECL”) model. The Company segregates accounts receivables into portfolio segments based on shared risk characteristics, such as line of business and customer type, for evaluation of expected credit losses. The Company makes estimates of expected credit losses based upon its assessment of various factors, including the age of accounts receivable balances, default-based statistics, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect its ability to collect from customers. The allowance for credit losses is developed using a loss rate method and is recognized in the Condensed Consolidated Statement of Operations. The uncollectible accounts receivables are written off on a quarterly basis in the period when collection activities cease due to a final determination that all or a portion of the balance is no longer collectible and if there is no pending litigation activity related to the receivable.

Inventories, net

Inventories, net

The Company accounts for inventory under Accounting Standard Codification Topic No. 330, Inventory (“ASC 330”). Inventories consist of intravenous chemotherapy drugs and oral prescription drugs. Inventories are stated at the lower of cost, determined using the weighted average cost method of inventory valuation, or net realizable value. Net realizable value is determined using the selling price, less costs to sell.

The Company receives purchase discounts on products purchased. Contractual arrangements with vendors, including manufacturers and wholesalers, normally provide for the Company to receive purchase discounts from established list prices in one, or a combination, of the following forms: (i) a direct discount at the time of purchase or (ii) a discount for the prompt payment of invoices. Additionally, in other circumstances, the Company may receive rebates when products are purchased indirectly from a manufacturer (e.g., through a wholesaler). These rebates are recognized when intravenous chemotherapy drugs and oral prescription drugs are dispensed and are generally calculated by manufacturers within 30 days after the end of each completed quarter. The Company also receives additional rebates under its wholesaler contracts if it exceeds contractually defined annual purchase volumes. Purchase rebates are recorded as reductions to cost of services.

Goodwill

Goodwill

The Company accounts for goodwill under ASC No. 350, Intangibles - Goodwill and Other (“ASC 350”). Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net assets acquired in our business combinations.

Goodwill is not amortized but is required to be evaluated for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company performs its annual testing of impairment for goodwill in the fourth quarter of each year. When impairment indicators are identified, the Company compares the reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between the reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit.

In assessing goodwill for impairment, an entity has the option to assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary. An entity can choose not to perform a qualitative assessment for any of its reporting units and proceed directly to the use of the two-step impairment test.

When assessing goodwill for impairment for the three months ended March 31, 2023, we first performed a qualitative assessment to determine whether it was necessary to perform the two-step quantitative analysis. Based on the qualitative assessment including our share price decrease as well as factors related to macroeconomic conditions, industry and market considerations, cost factors, financial performance and market capitalization, we determined it was likely that our reporting unit fair value was less than its carrying value and the two-step impairment test was performed.

Debt

Debt

The Company accounts for debt net of debt issuance costs and debt discount. Debt issuance costs and debt discount are

capitalized, netted against the related debt for presentation purposes, and amortized to interest expense over the terms of the related debt using the effective interest method. The Company accounts for bifurcated, debt-classified embedded features separately as derivative liabilities pursuant to ASC Topic No. 815, Derivatives and Hedging ("ASC 815"). Bifurcated, debt-classified embedded features are recorded at fair value on the Company's balance sheet with subsequent changes in fair value recorded in the Condensed Consolidated Statement of Operations each reporting period.

Investments in Marketable Securities

Investments in Marketable Securities

The Company's investments in marketable securities are classified as available-for-sale and are carried at fair value. The Company accounts for its investment securities available for sale using the fair value election pursuant to ASC 825, Financial Instruments ("ASC 825"), where changes in fair value are recorded in unrealized gains (losses), net on the Company's Condensed Consolidated Statements of Operations. The Company determines the appropriate classification of these investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company’s marketable securities are classified as current assets if the maturity date is less than one year from the balance sheet date.

Interest income and accretion on marketable securities are included in interest income in the Condensed Consolidated Statements of Operations. Realized gains and losses on sales of securities, and other-than-temporary declines in the fair value of marketable securities, if any, are included as a component of other income (expense), net in the Condensed Consolidated Statements of Operations. The cost of securities sold is based on the First In, First Out method.

At each reporting period, the Company evaluates available-for-sale marketable securities, to the extent the fair value option is not elected, for any credit-related impairment when the fair value of the investment is less than its amortized cost. If the Company determines that the decline in fair value is below the carrying value and this decline is other-than-temporary, credit-related impairment is recognized in the Consolidated Statement of Operations in accordance with ASC 320, Debt Securities. As of September 30, 2023, there were no available-for-sale instruments for which the fair value option was not elected.

Recently Adopted Accounting Standards and Recently Issued Accounting Standards

Recently Adopted Accounting Standards

In June 2016, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, instead of when incurred. In November 2018, the FASB issued Accounting Standard Update 2018-19, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2018-19”), which amends Subtopic 326-20 (created by ASU 2016-13) to explicitly state that operating lease receivables are not in the scope of Subtopic 326-20. Additionally, in April 2019, the FASB issued Accounting Standard Update 2019-04, Codification Improvements to Topic 326, Financial Instruments — Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments (“ASU 2019-04”); in May 2019, the FASB issued Accounting Standards Update 2019-05, Financial Instruments — Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”); in November 2019, the FASB issued Accounting Standards Update 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842):

Effective Dates and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments — Credit Losses (“ASU 2019-10”), and in March 2022, the FASB issued Accounting Standard Update 2022-02, Financial Instruments — Credit Losses: Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”), to provide further clarifications on certain aspects of ASU 2016-13 and to extend the nonpublic entity effective date of ASU 2016-13. The changes (as amended) are effective for the Company for annual and interim periods in fiscal years beginning after December 15, 2022. An entity may early adopt ASU 2016-13, as amended, for annual and interim periods in fiscal years beginning after December 15, 2018. ASU 2016-13 introduced a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including receivables, contract assets and held-to-maturity debt securities, which requires the Company to incorporate considerations of historical information, current information and reasonable and supportable forecasts. ASU 2016-13 also expands disclosure requirements.

The Company adopted the ASU 2016-13, as amended, effective January 1, 2023, which resulted in changes to the Company’s accounting policies for accounts receivables. Upon adoption of ASU 2016-13, the Company evaluated accounts receivables on a collective (i.e., portfolio) basis when similar risk characteristics were shared. The adoption of this standard did not have a material impact on our consolidated financial statements and there was no allowance for credit losses recorded as of September 30, 2023.

Recently Issued Accounting Standards

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06"), which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU 2020-06 also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. The new standard is effective for the Company beginning January 1, 2024. The Company is currently evaluating the effect of ASU 2020-06 on the Company’s consolidated financial statements and related disclosures.

In October 2021, the FASB issued ASU 2021-08, Business Combinations: Accounting for Contract Assets and Contract Liabilities from Contracts with Customers ("ASU 2021-08"). Under ASU 2021-08, an acquirer must recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contract with Customers (“ASC 606”). The guidance is effective for interim and annual periods beginning after December 15, 2023, with early adoption permitted. The Company will adopt ASU 2021-08 on January 1, 2024 on a prospective basis. The Company does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements and related disclosures.
