Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q (this “Form 10-Q”), including, without limitation, statements under the headings “Management's Discussion and Analysis of Financial Condition and Results of Operations,” contains forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995, including statements about the financial condition, results of operations, earnings outlook and prospects of American Oncology Network, Inc. (“AON”, “New AON”, “AON Inc.”, or the “Company”). Any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would” and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements are based on current expectations and projections about future events and various assumptions. AON cannot guarantee that it will actually achieve the plans, intentions, or expectations disclosed in its forward-looking statements and you should not place undue reliance on AON’s forward-looking statements.

These forward-looking statements involve a number of risks, uncertainties (many of which are beyond the control of AON), or other assumptions that may cause actual results or performance to differ materially from those expressed or implied by these forward-looking statements. The forward-looking statements contained herein are also subject generally to other risks and uncertainties that are described from time to time in AON’s filings with the Securities and Exchange Commission, including “Risk Factors” in the Company’s most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. The risks described in the “Risk Factors” sections are not exhaustive. New risk factors emerge from time to time, and it is not possible to predict all such risk factors, nor can AON assess the impact of all such risk factors on the business of AON, or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statement. The statements made herein are made as of the date of this press release and, except as may be required by law, AON undertakes no obligation to update them, whether as a result of new information, developments, or otherwise.

The operations of the practices above have been included in the Company’s condensed consolidated financial statements.
Business Combination Agreements

Digital Transformation Opportunities Corp. (“DTOC”), American Oncology Network, LLC (“AON LLC”), GEF AON Holdings Corp. (“AON Class C Preferred Investor”), and DTOC Merger Sub, Inc., a direct, wholly owned subsidiary of DTOC (“Merger Sub”) entered into a Business Combination Agreement (the “Business Combination Agreement”), dated as of June 14, 2023 (which further amended and restated the Business Combination Agreement entered into by DTOC and AON as of October 5, 2022, and amended and restated on January 6, 2023, and April 27, 2023), pursuant to which, among other transactions, on September 20, 2023 (the “Closing Date”), DTOC and AON undertook a series of transactions (the “Business Combination” or “Reverse Recapitalization”) resulting in the organization of the combined post-business combination company as an umbrella partnership C corporation, in which substantially all of the assets and the business of the combined company are held by AON LLC, and DTOC became a member of AON LLC. In connection with the closing of the Business Combination (“the Closing”), DTOC changed its name to “American Oncology Network, Inc.”. The Business Combination was completed on September 20, 2023.

As a result of, and in connection with, the Closing, among other things, (i) AON LLC amended and restated its operating agreement (the “Amended and Restated AON LLC Agreement”) to reclassify its existing Class A units, Class A-1 units and Class B units into a single class of AON LLC common units (“AON LLC Common Units”) that can be exchanged on a one-to-one basis for shares of New AON Class A common stock (“New AON Class A Common Stock”) and its existing AON LLC Class C units into AON LLC Series A preferred units (AON LLC Series A Preferred Units”); (ii) AON LLC converted profit pool units of certain of AON LLC’s subsidiaries into an equal number of AON LLC Common Units and shares of New AON Class B common stock (“New AON Class B Common Stock”), which together are exchangeable into shares of New AON Class A Common Stock (together with the New AON Class B Common Stock, the “New AON Common Stock”); (iii) New AON amended and restated its charter (the “Charter”) to provide for (a) the conversion of all existing shares of DTOC Class B common stock into shares of New AON Class A Common Stock on a one-to-one basis, (b) amendment of the terms
of New AON Class B Common Stock to provide holders voting rights but no economic rights and (c) designation of a new series of New AON preferred stock as Series A convertible preferred stock (the “New AON Series A
Preferred Stock” or “Series A Preferred Stock") with such rights and preferences as provided for in the certificate of designation of the New Aon Series A Preferred Stock (the “New AON Series A Certificate of Designation”); and (iv) among other things, (a) AON LLC issued common units to New AON in exchange for a combination of cash
5

and shares of New AON Class B Common Stock and warrants to acquire shares of New AON Class B Common Stock (the “Class B Prefunded Warrants”), (b) New AON was admitted as a member of AON LLC, (c) AON LLC distributed shares of New AON Class B common stock or Class B Prefunded Warrants, as applicable, to AON LLC equity holders, (d) New AON reserved a specified number of additional shares of New AON Class A Common Stock after the Closing for issuance to eligible participants, (e) Merger Sub merged with and into the AON Class C Preferred Investor whereby the separate existence of Merger Sub ceased and New AON issued a number of shares of New AON Series A Preferred Stock equal to the number of AON LLC Series A preferred units held by the AON Class C Preferred Investor to AEA Growth Management LP, the parent of AON Class C Preferred Investor (“AEA Growth”) in exchange for all the shares of common stock held by AEA Growth in the AON Class C Preferred Investor (the “First Step”), (f) promptly after the First Step, the AON Class C Preferred Investor merged with and into New AON whereby the separate existence of the AON Class C Preferred Investor ceased and New AON held all the AON LLC Series A preferred units and (g) from and after the Closing (but subject to lock-up restrictions), the AON LLC common equity holders (other than New AON), referred to herein as “Legacy AON Shareholders” (former AON LLC Class A, Class A-1, and Class B unit holders), will have the right (but not the obligation) to exchange AON LLC Common Units together with an equal number of shares of New AON Class B Common Stock (whether held directly or indirectly through Class B Prefunded Warrants) for shares of New AON Class A Common Stock.

In addition, in connection with the Closing, DTOC completed the offer to the holders of AON LLC Class B-1 units to exchange their AON LLC Class B-1 units for such number of newly issued shares of New AON Class A Common Stock equal to the ratio set forth in the Business Combination Agreement (such offer, the “Exchange Offer”). DTOC and AON LLC solicited consents from the holders of AON LLC Class B-1 units to make certain amendments to the terms of the awards and the unit grant agreements pursuant to which the AON LLC Class B-1 units were granted, which provided for the automatic exchange, as of immediately prior to the adoption of the Amended and Restated AON LLC Agreement, of all outstanding AON LLC Class B-1 units into shares of New AON Class A Common Stock (collectively, the “Proposed Amendments”). The requisite number of holders of Class B-1 units provided their consent to the Proposed Amendments, and as a result, in connection with the Closing, all AON LLC Class B-1 units were exchanged for an aggregate of 1,047,343 shares of New AON Class A Common Stock.

Upon the consummation of the Business Combination, the outstanding membership units in AON LLC and the outstanding shares in AON Inc. (New AON) are as follows:
AON LLC Common Units held by the Legacy AON Shareholders - 28,109,796
AON LLC Common Units held by New AON - 9,532,354

(a) Sponsor Earnout Shares of 2,839,375 are subject to vesting and forfeiture provisions and are not outstanding for GAAP purposes as of the Closing Date.

(b) Certain Legacy AON Shareholders hold 3,000,245 Class B Prefunded Warrants, which underlying shares of Class B common stock are not outstanding as of the Closing Date.

Warrants

As of the Closing Date, New AON assumed the outstanding warrants (Public Warrants and Private Placement Warrants) that were issued by DTOC as part of DTOC’s IPO. Further, New AON issued the Class B Prefunded Warrants to former Class A-1 unit holders, in lieu of New AON Class B Common Stock. The accounting treatment for the Public Warrants, the Private Placement Warrants, and the Class B Prefunded Warrants, collectively referred to as “the Warrants”, is disclosed in Note 2.

Public Warrants

6

As of the Closing Date, New AON assumed 8,337,500 public warrants (the “Public Warrants”) issued by DTOC in its IPO. Each whole warrant entitles the holder to purchase one share of New AON Class A Common Stock at a price of $11.50 per share, subject to adjustment. The warrants will become exercisable on the later of 12 months from the closing of the DTOC Initial Public Offering or 30 days after the completion of its initial business combination and will expire five years after the Closing of the Business Combination, or earlier upon redemption or liquidation.

Private Warrants

As of the Closing Date, New AON assumed 6,113,333 Private Placement Warrants held by the DTOC Sponsor (the “Private Placement Warrants” or “Private Warrants”). The Private Placement Warrants will be non-redeemable in certain circumstances so long as they are held by the Sponsor or its permitted transferees. The Private Placement Warrants may also be exercised by the Sponsor and its permitted transferees for cash or on a cashless basis. Otherwise, the Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants, including as to exercise price, exercisability, and exercise period.

Class B Prefunded Warrants

As of the Closing Date, New AON issued 3,000,245 of Class B Prefunded Warrants to former AON Class A-1 unitholders. Because the Class B Warrants are prefunded, there was not any cash consideration exchanged as part of the Class B Warrant issuance. Each Class B Prefunded Warrant entitles the holder to purchase one share of New AON Class B common stock at a price of $0.01 per share. The exercise term of the Class B Warrant shall continue indefinitely so long as the holder of the Class B Warrant is also the holder of an AON LLC Common Unit, provided that the number of shares of Common Stock that this Warrant is exercisable for shall not exceed the number of AON LLC Common Units held by holder.

Transaction Expenses

In connection with the Reverse Recapitalization, AON LLC and New AON incurred costs of $0.4 million and $1.9 million during the three months ended March 31, 2024 and 2023, respectively, which were reported as transaction expenses in the condensed consolidated statements of operations and comprehensive loss.

2.Basis of Presentation and Significant Accounting Policies
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements of the Company were prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. Management believes the unaudited condensed consolidated financial statements for the interim periods presented contain all necessary adjustments, of a normal recurring nature, to state fairly, in all material respects, the Company’s financial position, results of operations and cash flows for the interim periods presented. These unaudited condensed consolidated financial statements were prepared on the same basis as and should be read in conjunction with such audited consolidated financial statements and related notes thereto of AON Inc. and its wholly-owned subsidiaries, included in the Annual Report on Form 10-K, dated and filed on March 28, 2024 with the SEC (the “Annual Report 2023"). Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results the Company expects for the entire year.

For the three months ended March 31, 2024, these unaudited condensed consolidated financial statements reflect the consolidated results of operations, comprehensive loss, cash flows and changes in equity of AON Inc. and its wholly-owned subsidiaries. The condensed consolidated balance sheet at March 31, 2024 presents the financial condition of AON Inc. and its consolidated subsidiaries.

For the three months ended March 31, 2023, these unaudited condensed consolidated financial statements present the consolidated results of operations, comprehensive loss, cash flows and changes in equity of AON LLC. The condensed consolidated balance sheet as of December 31, 2023 presents the financial condition of AON Inc. and its consolidated subsidiaries after the Reverse Recapitalization. All intercompany balances and transactions of AON LLC have been eliminated.

In accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, the historical equity of AON LLC has been recasted in all periods up to the Closing Date, to reflect the number of shares of New AON’s Class A Common Stock and Class B Common Stock issued to Legacy AON Shareholders in connection with the Reverse Recapitalization. The Company recasted the units outstanding related to the historical AON LLC Class A, Class A-1, and Class B units prior to the Reverse Recapitalization (“Historical AON LLC Equity”) as common equity of New AON, equal to the Per Company Class Unit Exchange Ratio, pursuant to the Business Combination Agreement.

The Per Company Unit Exchange Ratio at which AON LLC Class A units and Class A-1 units were reclassified is equal to 2,524 AON Common Units. The Per Company Unit Exchange Ratio at which AON LLC Class B units were reclassified varied depending on participation threshold, and is equal to 2,524, 2,453, or 1,976, AON Common Units. The Per Company Unit Exchange Ratio at which Class C units were reclassified is equal to 2,705 AON LLC Series A Preferred Units.

The condensed consolidated financial statements and related notes thereto give effect to the conversion for all periods presented, without any change to par value or per unit amounts. The condensed consolidated financial statements do not necessarily represent the capital structure of New AON had the Reverse Recapitalization occurred in prior periods. The Company has not made retroactive adjustments related to the historical book values of Historical AON LLC Equity as the adjustments were considered immaterial.

For the three months ended March 31, 2024, $7.8 million of the consolidated net loss of AON LLC were attributable to the Class A Common Stockholders, and reflects the Class A Common Stockholders’ absorption of 23.0% of the consolidated net loss of AON LLC. For the three months ended March 31, 2024, $17.2 million of the consolidated net losses of AON LLC were attributable to noncontrolling interest, and reflects the Legacy AON Stockholders’ absorption of 77.0% of the consolidated net losses of AON LLC.

For the three months ended March 31, 2023, $1.5 million of the consolidated net losses of AON LLC were attributable to the Legacy AON Stockholders, to reflect their absorption of 100% of the consolidated net losses of AON LLC pertaining to the days prior to the Reverse Recapitalization.

Principles of Consolidation
For the period of January 1, 2024 through March 31, 2024, the condensed consolidated financial statements include the accounts of the Company, American Oncology Network, LLC (“AON LLC”), and its wholly owned subsidiary American Oncology Management Company, LLC (“AOMC”), and its consolidated variable interest entities (“VIEs”) American Oncology Partners, P.A. (“AON Partners”), American Oncology Partners of Maryland, P.A. (“Partners of Maryland”), AON Central Services, LLC (“AON Central Services”), and Meaningful Insights Biotech Analytics, LLC (“MIBA”). All intercompany accounts and transactions between the entities have been eliminated in consolidation.

The accounting treatment of the Business Combination was a Reverse Recapitalization.

For the periods prior to the Reverse Recapitalization, the consolidated financial statements of the Company comprise the accounts of AON LLC and its wholly-owned subsidiaries. All intercompany accounts and transactions among AON LLC and its consolidated subsidiaries were eliminated.
The Company accounts for American Oncology Network, LLC, AON Partners, Partners of Maryland, AON Central Services, and MIBA in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidations. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a VIE. A VIE is broadly defined as an entity that has any of the following three characteristics: (i) the equity investment at risk is insufficient to finance the entity’s activities without additional subordinated financial support; (ii) substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights; or (iii) the equity investors as a group lack any of the following, the power through voting or similar rights to direct the activities of the entity that most significantly impact the entity’s economic performance, the obligation to absorb the expected losses of the entity, or the right to receive the expected residual returns of the entity. The Company consolidates a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Management performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE will cause the consolidation conclusion to change. Changes in consolidation status are applied prospectively, if any.

AON LLC has contractual relationships with AON Partners, Partners of Maryland and AON Central Services and the physician owners through management service agreements (“MSAs”) and other contractual agreements to provide all practice management services outside of medical services provided by the physicians. In addition, despite not being required by the contractual relationships, AON LLC regularly provides funding to support AON Partners and Partners of Maryland’s operations and acquisitions of physician practices. AON Central Services was formed July 15, 2022 and, effective January 1, 2023, entered into an agreement with AOMC to provide qualified non-clinical and non-medical employees to AOMC to support the operation of the physician practices. MIBA was established during the first quarter of 2023 for the purpose of developing intellectual property to synergize the collection, de-identification, and dissemination of the Company’s patient data for sale to external parties for research, development, and clinical decisions. In May 2023, the Company contributed $0.2 million for a 56% interest in the equity of MIBA. As of March 31, 2024, MIBA had no significant operating activity. The Company concluded that AON LLC had a controlling financial interest in MIBA and has consolidated the entity at March 31, 2024 and recorded the noncontrolling interest in equity. 
The Company has concluded that AON Partners, Partners of Maryland, AON Central Services, and MIBA are all VIEs in which AON LLC has the characteristics of a controlling financial interest and is deemed to be the primary beneficiary. The variable interest subjects AON LLC to all potential losses in the entities and, therefore, requires AON LLC, and in turn AON Inc., to consolidate the results of AON Partners, Partners of Maryland, AON Central Services, and MIBA in its condensed consolidated financial statements. 
Refer to Note 4 for further information on the VIEs.
Significant Accounting Policies
The accounting policies included below should be read in conjunction with the annual consolidated financial statements.

Accounting Estimates and Assumptions
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
Segments
Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker (the “CODM”). The Company’s CODM is its chief executive officer who reviews financial information together with certain operating metrics principally to make decisions about how to allocate resources and to measure the Company’s performance. The Company has one operating segment and one reportable segment that are structured around the organizational management of oncology practice operations. All revenue and assets are in the United States. 
Revenue Recognition
Revenue is recognized under Accounting Standards Update (“ASU”) 2014-09 Revenue from Contracts with Customers (“Topic 606”). The Company determines the transaction price based upon standard charges for goods and services with anticipated consideration due from patients, third-party payors (including health insurers and government agencies) and others. The Company’s revenue is primarily derived from patient service revenues, which encompass oncology services provided during patient visits and shipments of pharmacy prescriptions. Performance obligations for the Company’s services provided to patients and most procedures, are satisfied over the time of visit which is the same day services are performed. Performance obligations relating to pharmacy revenue are considered fully satisfied at a point in time upon the customer receiving delivery of the prescription. Accordingly, the Company does not anticipate a significant amount of revenue from performance obligations satisfied (or partially satisfied) in previous periods, and any such revenue recognized during the three month periods ended March 31, 2024 and 2023 was immaterial. Additionally, the Company does not expect to recognize material revenue in the future related to performance obligations that are unsatisfied (or partially satisfied) as of March 31, 2024 and December 31, 2023. Approximately $246.1 million and $214.3 million and of the Company’s revenues are generated from services performed during patient visits with the remainder primarily generated from shipments of pharmacy prescriptions for the three month periods ended March 31, 2024 and 2023, respectively.
As services are performed and prescriptions are shipped, timely billing occurs for services rendered and prescriptions shipped less discounts provided to uninsured patients and contractual adjustments to third-party payors based upon prospectively determined rates and discounted charges. Payment is requested at the time of service for self-paying patients and for patients covered by third-party payors that are responsible for paying deductibles and coinsurance.
The Company monitors revenue and receivables to prepare estimated contractual allowances for the anticipated differences between billed and reimbursed amounts. Payments from third-party payors and Government programs including Medicare and Medicaid may be subject to audit and other retrospective adjustments. Such amounts are considered on an estimated basis when net patient revenue is recorded and are adjusted as final adjustments are determined. For the three month periods ended March 31, 2024 and 2023, such resulting historic adjustments have been immaterial to the condensed consolidated financial statements. 
In assessing who is the principal in providing patient services and pharmacy prescriptions, the Company considered who controls the provision of services and prescriptions. The Company has determined they are acting as a principal in these relationships. 
In April 2022, the Company entered into a long-term arrangement to sponsor and manage a clinical trial. The Company subsequently contracted with a third-party to provide the clinical research services and is the principal in this arrangement. The performance of clinical research services are considered a single performance obligation because the Company provides a highly-integrated service. Revenue is recognized for the single performance obligation over time due to the Company’s right to payment for work performed to date. The contract provides for invoices based on predetermined milestones. 

The Company uses the cost-to-cost measure of progress for the Company’s contract because it best depicts the transfer of control to the customer as the performance obligation is fulfilled. For this method, the Company
10

compares the contract costs incurred to date to the estimated total contract costs through completion. As part of the client proposal and contract negotiation process, the Company develops a detailed project budget for the direct costs and reimbursable costs based on the scope of the work, the complexity of the study, the geographical location involved and the Company’s historical experience. The estimated total contract costs at the project level are reviewed and revised periodically throughout the life of the contract, with adjustments to revenue resulting from such revisions being recorded on a cumulative basis in the period in which the revisions are identified. Contract costs consist primarily of direct labor and other reimbursable project-related costs such as travel, third-party vendor costs and investigator fees. The Company establishes pricing based on the Company’s internal pricing guidelines, discount agreements, if any, and negotiations with the client. The transaction price is the contractually defined amount. Revenue related to the clinical trial, which is included within other revenue, was $0.5 million and $0 million for the three months ended March 31, 2024 and 2023, respectively. 
The Company has a system and estimation process for recording Medicare net patient service revenue and estimated recoupments as it relates to value-based care (“VBC”) revenue included in patient service revenue in the condensed consolidated statements of operations and comprehensive loss. The Company’s VBC revenue is primarily generated through its participation in the CMS Oncology Care Model (“OCM”) which is an episode-based payment model to promote high-quality cancer care. Participants enter six-month episode periods, and the Company bills a monthly fee during the six-month period based on a fixed rate per participant per month and the total number of participants. Certain quality and compliance metrics are tracked as part of the program and submitted to CMS at the end of the episode period which may result in recoupment of funds. The Company estimates the recoupment amount by developing a recoupment percentage for each period based on historical known recoupment from CMS and applies the recoupment percentage against total fees for the period. Based on the estimate, the Company accrues a liability representing the expected final recoupments based on historical settlement trends.
Short-term Marketable Securities 
Investments in marketable securities consist of corporate bonds and U.S. Treasury securities.
Management determines the appropriate classification of investments at the time of purchase and reevaluates such determination at each balance sheet date. Marketable securities are classified as available-for-sale and are carried at fair value in the consolidated balance sheets. The marketable securities are classified as short-term based on management’s intent to convert such securities within one year and the ability to convert them within two to three days.
Certain of our available-for-sale securities are debt securities. For an available-for-sale debt security with an amortized cost that exceeds its fair value, the Company first determines if it intends to sell or will more-likely-than-not be required to sell the security before the expected recovery of its amortized cost. If it intends to sell or will more-likely-than-not be required to sell the security, then the Company recognizes the impairment as a credit loss in the condensed consolidated statements of operations and comprehensive loss by writing down the security’s amortized cost to its fair value. If it does not intend to sell or it is not more-likely-than-not that it will be required to sell the security before the expected recovery of its amortized cost, the Company recognizes the portion of the impairment that is due to a credit loss, if any, in the condensed consolidated statements of operations and comprehensive loss through an allowance. The portion of the impairment that is due to factors other than a credit loss is recognized in other comprehensive income (loss) in the condensed consolidated statements of operations and comprehensive loss as an unrealized loss.
Equity Investment in Affiliate
In January 2023, the Company contributed noncash consideration, with a fair value of approximately $2.3 million, in return for a 49% equity interest in OCP Management Arizona, LLP. Investments in entities over which the Company has the ability to exercise significant influence but does not control the entity are accounted for using the equity method. Equity method investments are included with other assets in the condensed consolidated balance sheets. The carrying amount of the investment is adjusted to reflect the Company’s proportionate share of the net earnings or losses and reduced by any dividends received. The Company’s share of income or loss related to this investment is reported as an equity in loss of affiliate in the condensed consolidated statements of operations and comprehensive loss.
11

Noncontrolling Interests
The Company consolidates the results of entities in which it has a controlling financial interest. Refer to Note 15 for additional considerations and presentation for noncontrolling interest.
Mezzanine Equity

New AON Series A Preferred Stock is redeemable for cash or the value of the property, rights or securities to be paid or distributed in the event of a Deemed Liquidation Event (which is outside of the Company’s control). As a result, Management has determined that the New AON Series A Preferred Stock should be classified as mezzanine equity. As of March 31, 2024, the Preferred Stock are recorded at their initial carrying value, net of offering costs of $0.8 million. The Series A Preferred Stock are not being accreted to redemption value, as the redemption is not probable. The Series A Preferred Stock are classified outside of members’ equity on the consolidated balance sheets. Refer to Note 14 for mezzanine equity presentation considerations for redeemable noncontrolling interest.
Treasury Stock

We account for treasury stock purchased under the cost method and include treasury stock as a component of
accumulated paid in capital. Treasury stock purchased with intent to retire (whether or not the retirement is actually accomplished) is charged to common stock. The company repurchased 14,729 shares of class A common stock at the spot rate as of each transaction date for a total cost of less than $0.1 million for the year ended December 31, 2023. For the three months ended March 31, 2024 the Company repurchased an additional 16,441 shares of class A common stock at the spot rate as of each transaction date for a total cost of less than $0.1 million. To date, the Company has repurchased a total of 31,170 shares.
Equity-Based Compensation

The Company issues stock-based awards to employees and directors in the form of stock options and restricted stock units. The Company measures and recognizes compensation expense for its stock-based awards granted to its employees and directors based on the estimated grant date fair value in accordance with ASC 718, Compensation-Stock Compensation, and determines the fair value of restricted stock units based on the fair value of its common stock. The Company measures all share-based options granted to employees and directors based on the fair value on the date of grant using the Black-Scholes option-pricing model. Compensation expense of those awards is recognized over the requisite service period, which is generally the vesting period of the respective award. The Company records the expense for awards with service-based conditions using the straight-line method over the requisite service period, net of any actual forfeitures. The Company classifies share-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.
Business Combinations
The Company evaluates acquired practices in accordance with ASU 2017-01, Business Combinations (Topic 805)-Clarifying the Definition of a Business. This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Because substantially all of the value of each acquired practice did not relate to a similar group of assets and as each acquired practice contained both inputs and processes necessary to provide economic benefits to the Company, it was determined that each acquisition represents a business combination. Therefore, the transactions have been accounted for using the acquisition method of accounting, which requires, with limited exceptions, that assets acquired, and liabilities assumed be recognized at their estimated fair values as of the acquisition date. Any excess of the consideration transferred over the estimated fair values of the net assets acquired is recorded as goodwill. Transaction costs related to business combinations are expensed in the period in which they are incurred.
Offering Costs
The Company defers specific incremental costs directly attributable to proposed offerings of securities. These costs consist of legal, accounting, and other similar expenses incurred through the balance sheet date that are directly related to a potential offering. If the offering is completed, these costs will be charged against the gross proceeds of the offering. These offering costs will be allocated to the separable financial instruments issued in the transaction on a relative fair value basis of the securities issued, compared to total proceeds received. Offering costs associated
12

with any instruments classified as liabilities will be expensed as incurred, presented as non-operating expenses in the condensed consolidated statement of operations and comprehensive loss.

Professional Liability
The Company maintains insurance policies for exposure to professional malpractice insurance risk. The limits of malpractice insurance provide each physician/advanced practice provider with a dedicated $1.0 million limit per claim and a $3.0 million limit in the aggregate per policy period – on a first dollar basis, as no deductible applies. The policy further then extends coverage to the Company, by providing a $2.0 million limit per claim and a $4.0 million limit in the aggregate per policy period - on a first dollar basis, additionally, as no deductible applies. Reserves are established for estimates of the loss that will ultimately be incurred on claims that have been reported but not paid and claims that have been incurred but not reported. These reserves are established based on consultation with a third-party actuary. The actuarial valuations consider a number of factors, including historical claims payment patterns, changes in case reserves and the assumed rate of increase in healthcare costs. Management believes the use of actuarial methods to account for these reserves provides a consistent and effective way to measure these subjective accruals. However, due to the sensitive nature of this estimation technique, recorded reserves could differ from ultimate costs related to these claims due to changes in claims reporting, claims payment and settlement practices and differences in assumed future cost increases. Accrued unpaid claims and expenses that are expected to be paid within the next twelve months are classified as current liabilities and included in accrued other. All other accrued unpaid claims and expenses are classified as long-term liabilities and included in other long-term liabilities. Insurance recoveries associated with the unpaid claims are classified as long-term assets included in other assets.
Fair Value of Financial Instruments
Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date.
Accounting guidance establishes a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:
Level 1Inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market.
Level 2Inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability.
Level 3Inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. 
Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement of assets and liabilities being measured within the fair value hierarchy.
Our financial instruments include cash, short-term marketable securities, accounts receivable, notes receivable, accounts payable, accrued expenses, long-term debt and contractual agreements that resulted in derivative liabilities. Our nonfinancial assets such as property and equipment are not measured at fair value on a recurring basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence that impairment may exist.
The carrying amounts of cash, accounts receivable, accounts payable, notes receivable, and accrued expenses approximate their fair value because of the short-term maturity and highly liquid nature of these instruments. We
13

determine the fair value of long-term debt and marketable securities based on various factors including maturity schedules and current market rates.
See Note 6 for a discussion of the Company’s Level 1 and Level 2 Marketable Securities as of March 31, 2024. See below for a discussion of the Company’s Level 1 and Level 3 warrant liabilities as of March 31, 2024. As of March 31, 2024 and December 31, 2023, there were no Level 3 financial instruments. There were no transfers between any levels of the hierarchy during any periods presented.

Warrant Liabilities

Upon Closing of the Business Combination, on September 20, 2023, the Company evaluated the Public Warrants and Private Placement Warrants and the Class B Prefunded Warrants, collectively referred to herein as “Warrants”, in accordance with ASC 815-40, “Derivatives and Hedging —- Contracts in Entity’s Own Equity”, and concluded that a provision in the warrant agreements related to potential net cash settlement of the warrants upon an exchange or tender offer that may not result in a change in control of the entity precludes the warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative as contemplated in ASC 815, the Warrants are recorded as current liabilities within accrued other on the condensed consolidated balance sheets and measured at fair value at inception and at each reporting date in accordance with ASC 820, “Fair Value Measurement”, with changes in fair value recognized in other income (expense), net on the condensed consolidated statements of operations and comprehensive loss in the period of change.

As of March 31, 2024, the Public Warrants were trading separately from the Class A Common Stock and the quoted market price was used to establish fair value. As such, the Public Warrants fair value was determined using a Level 1 input. The fair value of the Public Warrants as of March 31, 2024 is $2.8 million and recorded in other long-term liabilities on the condensed consolidated balance sheets.

Management has utilized the public warrant price to value the private warrants and believes the public and private warrants have materially consistent fair values given the existence of the make-whole redemption feature. As of March 31, 2024, a valuation of the private warrants was performed which confirmed the private warrant value was materially consistent with the public warrants. The details of this valuation are included in the paragraph below.

The fair value of the Private Placement warrants was determined using Level 3 inputs. As of March 31, 2024, the fair value of the Private Placement Warrants was estimated to be $2.1 million and recorded in other long-term liabilities on the condensed consolidated balance sheets. The fair value was estimated at March 31, 2024, using the Black-Scholes Option Pricing model using the following assumptions:
Expected annual dividend yield – 0.0%
                Expected volatility – 26.40%
                Risk-free rate of return – 4.31%
                Expected Option Term – 5.0 years
                
The AON Class B Prefunded Warrants are exercisable into one share of New AON Class B Common Stock. A share of New AON Class B Common Stock, together with an AON LLC Common Unit, may be exchanged for one share of New AON Class A Common Stock. Considering New AON Class B Common Stock has no economic rights and limited liquidity or value if the holder does not also possess an AON LLC Common Unit, and because the AON Class B Prefunded Warrants are exercisable into New AON Class B Common Stock, the Company has estimated fair value of the Class B Prefunded Warrants to be immaterial.
Earnings Per Share

The Company recast Historical AON LLC Equity as AON Inc. common equity for all periods prior to the Reverse Recapitalization, refer to Note 2. However, as 100% of the net losses of AON LLC prior to the Reverse Recapitalization were absorbed by the Legacy AON Shareholders, basic and diluted earnings (loss) per share is zero for the three months ended March 31, 2023. Basic and diluted earnings (loss) per share for the three months ended March 31, 2024 represents the period where the Company had earnings (loss) attributable to Class A Common Stockholders. Class B Common Stock does not have economic rights in AON Inc., including rights to dividends or distributions upon liquidation, and as a result, is not considered a participating security for basic and diluted earnings (loss) per share. As such, basic and diluted earnings (loss) per share of Class B Common Stock has not been presented.
14


The Company has issued and outstanding Sponsor Earnouts, which are subject to forfeiture if the achievement of certain stock price thresholds are not met. In accordance with ASC Topic 260, “Earnings Per Share,” the Sponsor Earnouts are excluded from weighted-average shares outstanding to calculate basic earnings (loss) per share as they are considered contingently issuable shares due to their potential forfeiture. Sponsor Earnouts will be included in weighted-average shares outstanding to calculate basic earnings (loss) per share as of the date of their stock price thresholds are met and they are no longer subject to forfeiture.

Basic and diluted earnings (loss) per share is computed by use of the two-class method as a result of outstanding Series A Preferred Stock, which accrue dividends at the annual rate of 8% of the original price per share, participate with common stock on all other dividends, and accordingly have participation rights in undistributed earnings as if all such earnings had been distributed during the period (see Note 12). Under such method income available to common shareholders is computed by deducting both dividends declared or, if not declared, accumulated on Series A Preferred Stock from net income. Loss attributable to common shareholders is computed by increasing net loss by such dividends. Since the participating Series A Preferred Stock has no contractual obligation to share in the losses of the Company, there is no loss allocation between Class A Common Stock and Series A Preferred Stock.

Basic earnings (loss) per share is based on the weighted-average number of shares of Class A Common Stock outstanding during the period. Diluted earnings (loss) per share is based on the weighted-average number of shares of Class A Common Stock used for the basic earnings (loss) per share calculation, adjusted for the dilutive effect of the Public and Private Warrants and Sponsor Earnout, if any, using the “treasury stock” method and the convertible Series A Preferred Stock and, exchangeable Class B Common Stock and Class B Prefunded Warrants, if any, using the “if-converted” method. Net earnings (loss) for diluted loss per share is adjusted for the Company’s share of AON LLC’s consolidated net earnings (loss), net of AON Inc. taxes, after giving effect to the Class B Common Stock and Class B Prefunded Warrants that are exchanged into potential shares of Class A Common Stock, Public and Private Warrants that are liability classified, and Series A Preferred Stock, to the extent it is dilutive.
Recently Adopted Accounting Pronouncements 
In June 2016, the FASB issued ASU 2016-13, ‘‘Financial instruments-Credit Losses’’ (“ASU 2016- 13”). ASU 2016-13 requires entities to report ‘‘expected’’ credit losses on financial instruments and other commitments to extend credit rather than the current ‘‘incurred loss’’ model. These expected credit losses for financial assets held at the reporting date are to be based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU will also require enhanced disclosures relating to significant estimates and judgments used in estimating credit losses, as well as the credit quality. ASU 2016-13 is effective for the Company for annual reporting periods beginning after December 15, 2022. ASU 2016-13 was adopted by the Company effective January 1, 2023, with no material impact 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”, which provides that an acquirer must recognize, and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606. The guidance is effective for the Company for annual reporting periods beginning after December 15, 2023, with early adoption permitted. The adoption of this standard as of January 1, 2024, did not have a material impact on the Company’s consolidated financial statements and related disclosures.
Recently Issued Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The amendments in this update are intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant expenses. The ASU requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker, a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the chief operating decision maker when deciding how to allocate resources. The ASU also requires all annual disclosures currently required by Topic 280, “Segment Reporting,” to be included in interim periods. This update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and retrospective application is required for all
15

periods presented. The Company is evaluating the impact this will have on the Company's consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The amendments in this upgrade enhance the transparency and decision usefulness of income tax disclosures. This ASU requires disclosures of specific categories and disaggregation of information in the rate reconciliation table. The ASU also requires disclosure of disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. The requirements of the ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted and the amendments should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating the effect that ASU 2023-09 will have on its disclosures.

3.Reverse Recapitalization

As discussed in Note 1, AON LLC merged with DTOC, with AON LLC surviving the Merger. AON LLC is governed by a board of managers composed of three (3) persons that were designated by New AON and two (2) persons that were designated by holders of a majority of the AON LLC Common Units, held by members of AON LLC other than New AON. Management determined AON LLC was not a variable interest entity (Refer to Note 2), and as result, identified AON LLC as the accounting acquirer of the Merger in accordance ASC Topic 805. Management concluded that AON LLC was the accounting acquirer due to (i) the Legacy AON Shareholders, defined as the former AON Class A, Class A-1, and Class B unit holders, receiving the largest portion of the voting rights in the combined company, New AON, (ii) significantly all of the Legacy AON Shareholders retained their equity interest as stockholders in New AON, (iii) AON LLC’s operations prior to the Reverse Recapitalization comprising the only ongoing operations of New AON, (iv) the Legacy AON Shareholders have the right to appoint a majority of the directors of New AON, (v) the executive management of AON LLC will become the executive management of New AON and (vi) AON LLC is significantly larger than New AON in terms of revenue, total assets, and employees. Therefore, the Merger was accounted for as a reverse recapitalization, with no goodwill or other intangible assets recorded, in accordance with ASC Topic 805. New AON was treated as the “acquired” company for financial reporting purposes, and for accounting purposes, the Reverse Recapitalization was treated as the equivalent of AON LLC issuing stock for the net assets of New AON, accompanied by a recapitalization. The net assets of New AON were recorded at historical cost on the condensed consolidated balance sheet as of September 20, 2023, the Closing Date of the Reverse Recapitalization, with no goodwill or other intangible assets recorded. For additional information on the capitalization of New AON and AON LLC immediately following the Closing of the Reverse Recapitalization, see Note 1.

The following table provides the historical cost of assets and liabilities of AON Inc. as of September 20, 2023.

As of September 20, 2023
Cash and Cash Equivalents$1,493 
Current Liabilities(13,295)
Long Term Liabilities(6,791)
Total Net Liabilities$(18,593)

The Company recorded a Day 1 expense as of the Closing of the Business Combination equal to $18.2 million. Of that total amount, $13.0 million was recorded in transaction expenses on the condensed consolidated statement of operations and comprehensive loss. The remaining $5.2 million was recorded in other income (expense) net on the condensed consolidated statement of operations and comprehensive loss. This amount represented the loss on the issuance of Public and Private Warrants, as of the Closing, net of cash received. The Company also recorded a $4.3 million gain in other income (expense), net related to the change in the fair value of the Public and Private Warrants during the period of September 21, 2023 through September 30, 2023.

4.Variable Interest Entities
AOMC is a wholly owned subsidiary of AON LLC and neither AOMC nor AON LLC has ownership interest in AON Partners and Partners of Maryland. Both AON Partners and Partners of Maryland are fully owned by physicians. AON LLC operates its physician practices through the MSAs and other contractual agreements between AOMC, AON Partners, and Partners of Maryland. The responsibilities of AOMC include, but are not limited to, negotiating provider and payor contracts, employment and compensation decisions, billing and collections, furnishing all supplies and equipment necessary for the respective practice’s operations as well as, necessary real estate, contracting on behalf of AON Partners and Partners of Maryland, entering into leases, holding a power of attorney to perform the above activities, preparing, maintaining and administering all accounting records (including financial reporting), expense payment, and maintenance of all information systems/software. AON LLC is paid a management fee to compensate AOMC for the services provided. AON Central Services is 80% physician owned and 20% owned by AON LLC. AOMC entered into an agreement with AON Central Services, effective January 1, 2023, to provide qualified non-clinical and non-medical employees to AOMC to support the operation of the physician practices. AOMC pays a monthly management fee to AON Central Services equal to the aggregate cost of compensation, benefits and all other costs related to these employees. AON LLC invested $0.2 million in MIBA, a newly formed LLC, during the second quarter of 2023 in exchange for 56% equity ownership. The Company evaluated AON LLC’s relationship with MIBA under the VIE model and determined it was a VIE and the Company is the primary beneficiary based on its financial controlling interest.

Based on various quantitative and qualitative factors, including assessment of certain services performed and relationships held above, management has determined that AON Partners, Partners of Maryland, AON Central Services, and MIBA are all variable interest entities and AOMC is the primary beneficiary who holds the decision-making rights over the activities that most significantly impact the economic performance of AON Partners, Partners of Maryland, AON Central Services, and MIBA through the MSAs and other contractual agreements. Accordingly, the results of AON Partners, Partners of Maryland, AON Central Services, and MIBA have been consolidated with the Company for the three month period ended March 31, 2024. The results of AON Partners, Partners of Maryland, and AON Central Services have been consolidated with the Company for the three month period ended March 31, 2023.

Credit Facilities
On April 30, 2021, the Company entered into a Loan Facility with PNC (“PNC Loan Facility”) collateralized by the Company’s assets and outstanding patient accounts receivable. The PNC Loan Facility is guaranteed on a limited basis by the Company and shareholder of AON Partners and Partners of Maryland. $34.6 million of proceeds from the PNC Loan Facility was used to pay off the Company’s previous term loans and revolver with Truist Bank. The remaining funds were made available for working capital and acquisition of additional physician practices.
The PNC Loan Facility is interest-only with total principal due at an initial maturity on April 30, 2024. Interest originally accrued at one-month LIBOR or an alternate base rate plus 1.45%. The maximum balance of the PNC Loan Facility (“Borrowing Base”) is limited to the lesser of the Facility Limit ($65.0 million) or the fair value of the Company’s patient accounts receivable. The Company must maintain a balance of the lesser of the Borrowing Base or 65% of the Facility Limit in the first year and 75% of the Facility Limit in subsequent years (“minimum funding threshold”). The Company can repay the PNC Loan Facility up to the minimum funding threshold at any time without penalty. In accordance with the PNC Loan Facility, the Company pledged $10.0 million of collateral as restricted cash to be released quarterly in increments of $2.5 million. The restricted cash was fully released as of March 31, 2024 and December 31, 2023.
On April 30, 2021, the Company entered into a $5.0 million revolving line of credit agreement (“PNC Line of Credit”). The PNC Line of Credit has an expiration date of April 30, 2024 and originally bore interest at a rate per annum equal to the sum of the daily LIBOR rate plus 1.65% or an alternate base rate plus 0.65% and is due on the first day of each month beginning June 1, 2021. Any outstanding principal and accrued interest will be due on the expiration date. Beginning July 1, 2021, quarterly bank fees equal to 1.65% per day per annum are due in arrears and will continue on the first day of each quarter thereafter. All debt related to the PNC Line of Credit is collateralized by the Company’s assets. As of March 31, 2024 and December 31 2023, no draws had been made on the PNC Line of Credit. The Company is also subject to a 0.20% unused line fee calculated per annum on the unused balance of the PNC Line of Credit. 
On July 29, 2021, the Company amended the PNC Loan Facility increasing the Facility Limit to $75.0 million. On February 14, 2022, the Company further amended the PNC Loan Facility and Line of Credit agreements. The primary changes included an increase of the Facility limit from $75.0 million to $125.0 million, an increase of the PNC Line of Credit availability from $5.0 million to $10.0 million, interest charges to be calculated based on the Bloomberg Short-Term Bank Yield Index plus 1.65% and certain financial covenants. As part of the amendment, the Company drew an additional $16.3 million in proceeds under the Loan Facility. On August 15, 2022, the PNC Loan Facility and Line of Credit agreements were amended again to reduce the availability under the PNC Line of Credit from $10.0 million to $1.0 million. 
Effective November 23, 2022, the Company entered into Waiver and Amendment No. 6 (“Waiver and Amendment”) under its PNC Loan Facility as the Company was not in compliance with the Delinquency Ratio financial covenant for the period ending October 31, 2022 and the requirement to provide certain annual financial statements. The Waiver and Amendment waives each event of default and also revised future delinquency percentages and financial statement requirements. 
On June 30, 2023, the Company entered into Amendment No. 7 (“Amendment 7”) to its PNC Loan Facility which extended the maturity date from April 30, 2024 to June 30, 2026. In connection with Amendment 7, the Company paid additional debt issuance costs of $0.4 million which will be amortized over the revised remaining life of the
24

Loan Facility. In addition, Amendment 7 revised the definition of the minimum funding threshold to limit the threshold multiplier to 65% of the Facility Limit. 

On January 1, 2024, the Company entered into Amendment No. 8 (“Amendment 8”) to its PNC Loan Facility to modify certain definitions such as “change in control”. In addition, the Amendment 8 also amended the delinquency ratio threshold used to calculate certain debt covenants. The effective date of Amendment 8 was January 16, 2024.

On January 16, 2024, the Company also entered into Amendment No. 3 (“Amendment 3”) to its PNC Line of Credit to modify certain definitions such as “change in control”. In addition, the Amendment 3 also amended certain debt covenants, such as EBITDA thresholds. The effective date of Amendment 3 was December 31, 2023.

The PNC Loan Facility and PNC Line of Credit nonfinancial covenants include restrictions related to unpermitted property liens and the requirement of audited financial statements. Both agreements also contain several financial covenants, including the following ratios: accounts receivable default, delinquency, dilution, days sales outstanding, leverage, and fixed charge coverage. As of March 31, 2024, the Company was in compliance with all financial and nonfinancial debt covenants as required by both loan agreements.

9. Income Taxes

The Company is a member of American Oncology Network, LLC, which is treated as a partnership for U.S. federal and certain state and local income taxes. As a partnership, American Oncology Network, LLC is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by American Oncology Network, LLC is passed through to and included in the taxable income or loss of its members, including the Company.

The Company is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to the allocable share of any taxable income of American Oncology Network, LLC. Additionally, other corporate entities within the Company's structure are subject to income taxes. These corporate entities continue to generate losses and continue to maintain a valuation allowance against their net deferred tax assets.

The Company’s effective income tax rate was (13.1)% and 0.0% for the three months ended March 31, 2024 and 2023, respectively. The provision for income taxes was $2.9 million and $0 for the three months ended March 31, 2024 and 2023, respectively.

The change to the income tax provision for the three months ended March 31, 2024 compared to the income tax provision for the three months ended March 31, 2023 was primarily a result of the transaction closing on September 20, 2023, resulting in a portion of the Company's consolidated pre-tax earnings, which were previously not subject to income taxes, flowing into a taxable corporation included in the Company's post transaction structure. As of December 31, 2023, the Company recognized a deferred tax asset related to its investment in the American Oncology Network, LLC partnership. As of March 31, 2024, the Company updated its valuation allowance assessment based on new factors including its year-to-date loss and forecasted loss at the American Oncology Network, LLC partnership legal entity. Based on its updated valuation allowance assessment, the Company recorded a discrete valuation allowance against its investment in partnership deferred tax asset during the three months ending March 31, 2024.

The effective income tax rate for the three months ended March 31, 2024 and 2023 differed from the federal statutory rate primarily due to certain legal entities in the Company's structure being treated as partnerships for income tax purposes and, therefore, a significant portion of its income not being subject to income tax. Additionally, certain corporate entities within the Company's structure continue to maintain a full valuation allowance against their net deferred tax assets.

12. Equity-Based Compensation

The Company maintains a single equity incentive plan, the “2023 Incentive Equity Plan”, which was adopted by the Board of Directors and approved by stockholders in connection with the Business Combination. A total of 5,300,000 shares were authorized under the 2023 Incentive Equity Plan. The number of shares of common stock available for issuance under the 2023 Incentive Equity Plan will be increased annually on the first day of each fiscal year during the term of the 2023 Incentive Equity Plan by an amount equal to the lesser of (a) 5% of the shares of common stock outstanding on the final day of the immediately preceding calendar year or (b) such smaller number of shares as determined by the Company’s board of directors. At March 31, 2024, 2,044,394 shares were available for grant under the 2023 Incentive Equity Plan. The purpose of the 2023 Incentive Equity Plan is to attract and retain personnel for positions with the Company, to provide additional incentive to employees, directors, and consultants, and to promote the success of the Company’s business. The Plan permits the grant of Incentive Stock Options (“ISO”) to any ISO Employee and the grant of Non statutory stock options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, and Performance Awards to any Service Provider.

Restricted Stock Units

The Company granted 3,759,459 Restricted Stock Units (“RSUs”) to employees during the three months ended March 31, 2024.

A summary of the RSU activity during the three month period ending March 31, 2024 is as follows:

Restricted Stock UnitsWeighted Average Grant Date Fair Value
Outstanding as of December 31, 2023— $— 
Granted3,759,459 $5.73 
Vested(2,289,181)$5.80 
Forfeited— $— 
Outstanding as of March 31, 20241,470,278 $5.67 

The Company recognized $13.3 million in stock-based compensation expense related to outstanding RSUs during the three months ended March 31, 2024.

As of March 31, 2024, there was approximately $8.2 million of total unrecognized compensation expense related to RSUs, which is expected to be recognized over a weighted-average period of approximately 1.7 years.

The fair value of the RSUs is determined on the date of the grant based on the market price of the Company’s common stock on that date. Each RSU represents the right to receive one share of the Company’s common stock, upon vesting. Portions of the RSUs granted vest immediately with others vesting over one to two years following the grant date, subject to the individual’s continued service to the Company through the applicable vesting date, and are subject to the terms and conditions on the Company’s form of RSU agreement under the 2023 Incentive Equity Plan.

13. Equity

Prior Period Presentation

For periods prior to the Reverse Recapitalization, AON LLC had equity and stock-based compensation described below authorized, issued and outstanding. As discussed in Note 1, upon the Closing of the Business Combination, Legacy AON Shareholders received Class A Common Stock, Class B Common Stock, or Class B Prefunded Warrants and AON LLC reclassified their existing Class A, Class A-1, and Class B Units into AON LLC Common Units, pursuant to the terms of the Business Combination Agreement.

The Company recasted Historical AON LLC Equity outstanding for the periods prior to the Reverse Recapitalization, equal to the Per Company Unit Exchange Ratio, pursuant to the Business Combination, that was applied to the Class A, Class A-1, and Class B Units. The historical AON LLC units disclosed in this note give effect to the conversion for all periods presented, as follows.

Class A Units

AON LLC had authorized 19,495,376 units of Class A Units, of which 19,495,376 units were issued and were outstanding as of December 31, 2022.

Class A-1 Units

AON LLC had authorized 3,000,245 units of Class A-1 Units, of which 1,842,520 units were issued and were outstanding as of December 31, 2022.

Class B Units (Profit Interest)

The Class B units were issued through the 2017 Profits Interest Plan adopted by the Company in October 2017. The Class B Units represented a non-voting equity interest in AON LLC that entitled the holder to appreciation in the equity value of AON LLC arising after the date of grant and after such time as an applicable hurdle amount is met. AON LLC recognized the cost of services received in exchange for Class B Units based on the grant-date fair value. That cost was recognized over the period during which the service provider is required to provide service in exchange for the award over the requisite service period or based on performance. AON LLC used the Black-Scholes-Merton pricing model to estimate the fair value of profits interest unit awards. On an as converted basis, as of December 31, 2022, AON LLC issued 5,614,176 Class B Units, of which 4,703,628 were vested and outstanding; the remaining 910,548 of Class B units vested upon consummation of the Business Combination.

The following table summarizes the changes to AON LLC’s Class A, Class A-1, and Class B Units for the three months ended March 31, 2023.

Class B-1 Units

In June and July of 2023, the Company granted a total of 415 AON LLC Class B-1 Units to certain employees under the 2017 Profits Interest Plan (the “Plan”). Upon the closing of the Business Combination, the vested Class B-1 Units were reclassified to AON LLC Common Units and exchanged for newly issued shares of Class A Common Stock equal to the Per Company Unit Exchange Ratio, pursuant to the Business Combination Agreement, which resulted in the issuance of 1,047,343 shares of New AON Class A Common Stock.

Mezzanine Equity Class C Units

As described in Note 1, the AON LLC Class C Units were converted into AON LLC Series A Preferred Units as of the Closing Date. Concurrently, New AON issued a number of shares of New AON Series A Preferred Stock equal
32

to the number of AON LLC Series A Preferred Units held by the AON Class C Preferred Investor to AEA Growth Management LP, the parent of AON Class C Preferred Investor (“AEA Growth”) in exchange for all the shares of common stock held by AEA Growth in the AON Class C Preferred Investor. Promptly after the First Step, the AON Class C Preferred Investor merged with and into New AON whereby the separate existence of the AON Class C Preferred Investor ceased and New AON held all the AON LLC Series A Preferred Units. On an as converted basis, as of September 20, 2023, 6,651,610 Series A Preferred Stock were issued to AEA Growth Management LP.

The AON LLC Class C Units were contingently redeemable convertible preferred units and classified as mezzanine equity on the condensed consolidated balance sheet as of June 30, 2023 because the units were redeemable five years from the issuance date, at the option of the holder. As of June 30, 2023, the AON LLC Class C Units were recorded at their initial carrying value, net of offering costs. The Class C Units were not being accreted to redemption value, as the redemption was not probable due to the removal of the redemption right pursuant to the Business Combination. See discussion below.

The Class C Units had materially the same rights as the Series A Preferred Stock issued by the Company to AEA Growth Management LP, the parent of the AON Class C Preferred Investor, with the exception of the “AON LLC Class C Unit Redemption Right” and the “Class C Option to Purchase Additional Shares”, discussed below. Further, the Class C Units did not contain a mandatory conversion feature that allowed AON LLC to force the Class C Investor to convert the Class C Units into another equity unit in AON LLC and the Class C Units did not have a one time conversion price adjustment.

Class C Unit Redemption Right

After the fifth anniversary of the Effective Date (June 7, 2028), the holders of a majority of the Class C Units had the right to cause the Company to redeem all of the Class C Units. The redemption price per Class C Unit was equal to the greater of (i) the Class C Liquidation Preference and (ii) the Fair Market Value of a Class C Unit (the “Class C Redemption Price”). The Class C Liquidation Preference is defined as an amount equal to the sum of (a) the Class C Preferred Return of such Class C Member and (b) the amount of such Class C Member’s Net Invested Capital Contributions of $65.0 million. The Class C Unit Preferred Return is defined as the cumulative, semiannually-compounded return of 8% per annum based on the original Net Invested Capital Contributions of $65.0 million. The Class C Unit Redemption Right was removed as of the Closing of the Business Combination.


Series A Preferred Stock (Mezzanine Equity)

New AON Series A Preferred Stock is redeemable for cash or the value of the property, rights or securities to be paid or distributed in the event of a Deemed Liquidation Event (which outside of the Company’s control). As a result, the Company has determined that the New AON Series A Preferred Stock should be classified as mezzanine equity. At the closing of the Business Combination, the Company exchanged existing AON LLC Class C Units for Series A Preferred Stock in the Company. Based on the qualitative changes to the instrument, this exchange is considered an extinguishment for accounting purposes, with the Company recording a deemed dividend of $2.1 million to account for the difference between the carrying value of the Class C Units and the fair value of the Series A Preferred Stock at the transaction date. This amount is reflected in the December 31, 2023 condensed consolidated statements of mezzanine and stockholders’ equity as part of the reverse recapitalization, net. See further discussion on the PIK Dividend discussed below.

The Series A Preferred Stock are not being accreted to redemption value, as the Series A Preferred Stock are not redeemable, nor are they probable of becoming redeemable.

Dividends

The Series A Preferred Stock accrue dividends at a cumulative, semiannually-compounded return of 8% per annum based on the original Net Invested Capital Contributions from the Class C Units of $65.0 million. These dividends may be paid in cash or accumulate into the Accrued Value at the option of New AON. The accrual shall be calculated on June 30 and December 31 and with respect to the semiannually-compounded return, no interest is required to be paid on any present or future Series A Preferred Stock accrued dividends. The Series A Preferred Stock also participate in distributions with the Class A Common stockholders.

33

On September 20, 2023, the Company issued 6,651,610 Series A Preferred Stock to AEA Growth Management LP. The number of Series A Preferred Stock shares issued at the Closing of the Business Combination was equal to the aggregate Class C Liquidation Preference pursuant to the Business Combination Agreement. As a result, the issuance of the Series A Preferred Stock effectively included an in-kind payout (“PIK”) of the accrued dividend since the calculation of the amount issued was based on the Class C Liquidation Preference. As of the Closing, the Company recorded a dividend of 151,610 Series A Preferred Stock PIK shares with respect to the accrued dividends on the Series A Preferred Stock (the "PIK Dividend") in the December 31, 2023 condensed consolidated statements of mezzanine and stockholders’ equity.

Voting

The holders of the Preferred Stock are entitled to elect and appoint one of the directors (“Series A Director”) to the Board of Directors. All other directors are appointed by the Class A and Class B Common stockholders. There are no restrictions on which matters the Series A Preferred stockholders are entitled to vote. The Series A Preferred stockholders are entitled to the number of votes equal to the number of shares of Common Stock into which the Series A Preferred Stock would be convertible on the record date of the vote.

Conversion Rights

The Series A Preferred Stock is convertible, at the option of the holder, at any time, and without the payment of additional consideration by the holder, into such number of fully-paid Class A Common Stock as is determined by dividing the Accrued Value by the Conversion Price in effect at the time of conversion (“Conversion Ratio”). The Accrued Value is the Original Issue Price (which is $10.00 per share of Preferred Stock, as adjusted for any stock split, stock dividend, combination, or other recapitalization) plus any unpaid dividends, compounded semi-annually. The Conversion Price is initially $10.00 per Preferred Share subject to adjustment for dilutive issuances of additional shares, dividends to common stockholders, stock splits, mergers, and a five-year anniversary special adjustment based on the volume weighted average price of the common stock. These dividends may be paid in cash or accumulate into the Accrued Value, at the option of New AON, on June 30 and December 31 of each year. The Conversion Rights shall terminate at the close of business on the day prior to the date of a Change of Control.

If at any time on or after the 30th day after the five-year anniversary of the issue date, any of the Series A Preferred Stock remain outstanding and the 30-Day VWAP of the Common Stock is less than $10.00 (as adjusted for any stock split, stock dividend, combination, or other recapitalization or reclassification), then the Conversion Price shall be adjusted to the greater of (x) the 30-Day VWAP on such date of determination and (y) $5.00 (as adjusted for any stock split, stock dividend, combination, or other recapitalization or reclassification).

New AON also has the right on or after the third-year anniversary of the date of issuance to cause all (but not less than all) of the outstanding shares of Series A Preferred Stock to be converted into shares of Class A Common Stock for each share of Series A Preferred Stock at the Conversion Ratio detailed above. The Company may only convert shares of Series A Preferred Stock into shares of Common Stock if the 30-Day VWAP of the Common Stock immediately prior to the Company Conversion Date is greater than $16.00 (as adjusted for any stock split, stock dividend, combination, or other recapitalization).

Liquidation Preferences

In the event of voluntary or involuntary liquidation, dissolution or winding up of the Company or an Initial Public Offering (IPO) or Exit Event, the Series A Preferred Stock have preferential liquidation rights. If a Deemed Liquidation Event were to occur, each Series A Preferred stockholder is entitled to be paid out of the assets of the Company available for distribution, equal to the greater of the following:

(i) The Original Issue Price of $10 per Series A Preferred Stock multiplied by the Applicable Percentage plus any Accrued Dividends on such share of Series A Preferred Stock; or

(ii) Such amount per share as would have been payable had all shares of Series A Preferred Stock been converted into Common Stock immediately prior to such Deemed Liquidation Event.

The Series A Preferred Stock Applicable Percentage is defined as a percentage equal to (a) one hundred twenty-five percent (125%) if an Exit Event, dissolution, liquidation, or winding-up occurs prior to June 7, 2024, (b) one
34

hundred twenty percent (120%) if an Exit Event, dissolution, liquidation, or winding up occurs after June 7, 2024, but prior to June 7, 2025, (c) one hundred fifteen percent (115%) if an Exit Event, dissolution, liquidation, or winding-up occurs after June 7, 2025, but prior to June 7, 2026, (d) one hundred ten percent (110%) if an Exit Event, dissolution, liquidation, or winding up occurs after June 7, 2026, but prior to June 7, 2027, (e) one hundred five percent (105%) if an Exit Event, dissolution, liquidation, or winding-up occurs after June 7, 2027, but prior to June 7, 2028, (f) one hundred percent (100%) if an Exit Event, dissolution, liquidation, or winding-up occurs after June 7, 2028.

Distributions to Class A and Class A-1 Members

On March 4, 2020, the AON LLC entered into the Second Amended and Restated Limited Liability Agreement (“Second Operating Agreement”) which established another class of equity, Class A-1 Units. The Second Operating Agreement provided, among other things, that the Class A and A-1 Units would receive a cumulative, annually-compounded, preferred return of 8.0% and 4.0%, respectively, on capital contributions when and if distributions are declared by the Board of the Company.

Prior to the issuance of the Class C Units on June 7, 2023 as discussed above, the Class A and A-1 unitholders were paid a cash distribution of $4.0 million and $4.1 million, respectively, representing the cumulative accrued preferred return to June 7, 2023.

On June 7, 2023, in connection with the issuance of the Class C Units, AON LLC entered into the Third Amended and Restated Limited Liability Agreement (“Third Operating Agreement”) which, among other things, eliminated any provisions for future preferred returns on Class A and A-1 units.

14. Net Loss Per Share

The following table sets forth the computation of basic and diluted net loss per share of Class A Common Stock and represents the period from January 1, 2024 to March 31, 2024, the period where the Company had Class A and Class B common stock outstanding. Class B Common Stock does not have economic rights in AON Inc., including rights to dividends or distributions upon liquidation, and as a result, is not considered a participating security for basic and diluted loss per share. As such, basic and diluted loss per share of Class B Common Stock has not been presented. Series A Preferred Stock are considered participating securities for basic and diluted loss per share, but do not participate in losses. As such, basic and diluted loss per share is computed using the two-class method. For additional information, see Notes 1 and 2.

Basic loss per share is based on the weighted-average number of shares of Class A Common Stock outstanding during the period. Diluted loss per share is based on the weighted-average number of shares of Class A Common Stock used for the basic loss per share calculation, adjusted for the dilutive effect of Public and Private Warrants, Restricted Stock Units, and Sponsor Earnouts, if any, using the “treasury stock” method and the convertible Series A Preferred Stock, Class B Common Stock, and Class B Prefunded Warrants, if any, using the “if-converted” method. Net loss for diluted loss per share is adjusted for the Company’s share of AON LLC’s consolidated net loss, net of AON Inc. taxes, after giving effect to Class B Common Stock and Class B Prefunded Warrants that are exchanged into potential shares of Class A Common Stock, Public and Private Warrants that are liability classified, and Series A Preferred Stock that accrue dividends, to the extent it is dilutive.

Net loss attributable to Class A Common Stockholders for basic and diluted earnings per share$(7,841,000)
Series A Preferred Cumulative Dividends(1,360,180)
Undistributed loss for basic earnings per share$(9,201,180)
Weighted-average shares for basic earnings per share7,527,882 
Basic and Diluted loss per share of Class A Common Stock$(1.22)

The following table details the securities that have been excluded from the calculation of weighted-average shares for diluted loss per share for the period presented as they were anti-dilutive. Note that the Sponsor Earnouts are excluded from the calculation of weighted-average shares for diluted loss per share as the contingency had not been met as of the period end.

15. Redeemable Noncontrolling Interest

Legacy AON Shareholders own 26,726,243 AON LLC Common Units, equal to a 61.1% of the economic interest in AON LLC. Legacy AON Shareholders also own 23,725,998 shares of Class B Common Stock and 3,000,245 Class B Prefunded Warrants, which, together with the AON LLC Common Units, may be redeemed at the option of the Legacy AON Shareholder on a one-for-one basis for shares of Class A Common Stock or the cash equivalent thereof (based on the market price of the shares of Class A Common Stock at the time of redemption) as determined by New AON. If New AON elects the redemption to be settled in cash, the cash used to settle the redemption must be funded through a private or public offering of Class A Common Stock no later than ten (10) business days after the redemption notice date. Upon the redemption of the AON LLC Common Units and Class B
Common Stock for shares of Class A Common Stock or the equivalent thereof, all redeemed shares of Class B Common Stock will be cancelled. The redemption value is determined based on a five-day volume weighted average price (”VWAP”) of the Class A common shares, subject to customary conversion rate adjustments for share splits, share dividends, and similar events affecting Class A Common Stock.

When applying SEC guidance concerning mezzanine classification, the Company understands that due to the NCI holders having control of the Board, if there is a sequence of remotely possible events that could trigger a redemption, this requires the instrument to be classified as temporary equity, without any regard to probability. Accordingly, though the redemption would require such a remotely possible sequence of events, and such remote sequence of events would also require, in management’s view, the Company to take extraordinary actions in order to allow such sequence of events to be remotely possible, the noncontrolling interest is currently classified as temporary equity. In the event that the Legacy AON Shareholders own less than 50% of the outstanding economic interest in AON LLC Common Units due to future redemptions, the noncontrolling interest will be presented as permanent equity.

The redeemable noncontrolling interest is recognized at the greater of (1) its initial fair value plus accumulated earnings/(losses) associated with the noncontrolling interest or (2) the redemption value as of the balance sheet date. At March 31, 2024, the redeemable noncontrolling interest was recorded based on its redemption value of $157.7 million which exceeded its carrying value by $15.6 million. This measurement adjustment decreased additional paid in capital by $9.7 million and retained deficit by $5.9 million. At the end of each reporting period, AON LLC equity attributable to AON Inc. and the Legacy AON Shareholders is rebalanced to reflect AON Inc.’s and the Legacy AON Shareholder’s ownership in AON LLC.


The following table summarizes the economic ownership of AON LLC, for the period beginning December 31, 2023 and ending March 31, 2024.

Overview
Since its inception in 2018, AON has offered an innovative model of physician-led, community-based oncology management. AON preserves and elevates community oncology by helping its physicians navigate the complex healthcare landscape, providing them an efficient platform to work autonomously and thrive, and most importantly, improving the quality of patient care that is being delivered. We are an alliance of physicians and veteran healthcare leaders partnering to ensure the long-term success and viability of oncology diagnosis and treatment in community-based settings. As of March 31, 2024, we have approximately 220 physicians and advanced practice providers across 91 locations in 19 states and the District of Columbia. Our robust platform provides oncology practices with comprehensive support, access to revenue- diversifying adjacent services and practice management expertise to empower physicians to make cancer care better for every patient.
Our mission is to provide high quality, cost effective cancer care close to where patients live and work. We believe the key to accessible and equitable healthcare lies in the strength of community healthcare practices and we are committed to closing the gap in cancer care to ensure every patient has access to the optimal, comprehensive care needed to help in their fight against cancer. To accomplish this, we have practices in some of the most densely populated cities as well as rural areas where medical resources are scarce. We deliver cancer care innovation by bringing new treatments to the forum and also by ensuring access to the necessary adjacent services to provide comprehensive quality cancer care and preserving the delivery of personalized cancer care in the community oncology setting.
Through access to care-enhancing patient services such as a centralized specialty pharmacy, wide ranging clinical lab and pathology services, clinical research, diagnostic imaging, a fully integrated technology platform anchored by an oncology- specific electronic medical record system, as well as a caring management team and a variety of financial assistance programs, our patients receive expert cancer care at each of our clinics.
We provide patients a variety of services to enhance patient care throughout the healthcare journey: high-quality and timely laboratory services for routine and specialized testing; in-house professional and technical pathology services providing complete, accurate and timely pathology reports; in-house specialty pharmacy with patient education, financial assistance, and 24/7 patient assistance; and care management support services including nutrition guidance.
As the future of healthcare continues to transition from volume to value, we are at the forefront of this initiative by ensuring we remain focused on care quality over care quantity and maintaining a patient-first mentality. Through an integrated system of seamless communication, coordination and patient care for better health outcomes, AON practices benefit from decreased expenditures through the implementation of centralized administrative services, processes, and technologies designed to support effective decision- making such as optimal pricing on drugs and medical supplies. Our patients benefit through our 24/7 clinical care support leading to a reduction in unnecessary emergency room visits and admissions and enhanced care quality. Ultimately, the payors benefit from more efficient delivery of high-quality, comprehensive services comparable to any hospital system at a lower cost point.
39

Though our network spans the country, our clinicians are interconnected and focused on driving change not just at their local clinics, but throughout our network. Our Network Practices not only unite in collaboration through a physician advisory board, but they also remain at the forefront of new discoveries and findings by expanding and improving cancer treatment options for every patient through a Pharmacy and Therapeutics Committee that continuously updates its formulary in real time as advanced therapeutics come to market and through participating in clinical research to ensure we remain on the cutting edge of cancer protocols. Patients benefit from convenient access to clinical trials that we participate in without the need to travel to large cities or tertiary cancer care facilities, and personalized care by matching a patient’s cancer to a tailored therapy using molecular profiling.
We have invested significantly in a resilient, integrated technology platform to support the practices which includes a fully integrated electronic health record and a robust decision support tool and analytics engine. Our development of compliance materials ensures consistency and optimal patient experiences that meets or exceeds the Office of Inspector General (“OIG”) guidelines.
We believe that our position in the market and focus on elevating the state of oncology care with our affiliated providers bodes well for future growth. Our proprietary technology platform supports this growth and enables the Network Practices to standardize and deliver consistent care at scale. We believe that our model will support growth into new markets and allow us to continue to service more patients across the United States.

(“AON Class C Preferred Investor”), and DTOC Merger Sub, Inc., a direct, wholly owned subsidiary of DTOC (“Merger Sub”) entered into a Business Combination Agreement (the “Business Combination Agreement” or “Reverse Recapitalization”), dated as of June 14, 2023 (which further amended and restated the Business Combination Agreement entered into by DTOC and AON as of October 5, 2022, and amended and restated on January 6, 2023, and April 27, 2023), pursuant to which, among other transactions, on September 20, 2023 (the “Closing Date”), DTOC and AON undertook a series of transactions (the “Business Combination”) resulting in the organization of the combined post-business combination company as an umbrella partnership C corporation, in which substantially all of the assets and the business of the combined company are held by AON LLC, and DTOC became a member of AON LLC. In connection with the closing of the Business Combination (“the Closing”), DTOC changed its name to “American Oncology Network, Inc.”. The Business Combination was completed on September 20, 2023.

As a result of, and in connection with, the Closing, among other things, (i) AON LLC amended and restated its operating agreement (the “Amended and Restated AON LLC Agreement”) to reclassify its existing Class A units, Class A-1 units and Class B units into a single class of AON LLC common units (“AON LLC Common Units”) that can be exchanged on a one-to-one basis for shares of New AON Class A common stock (“New AON Class A Common Stock”) and its existing AON LLC Class C units into AON LLC Series A preferred units (AON LLC Series A Preferred Units”); (ii) AON LLC converted profit pool units of certain of AON LLC’s subsidiaries into an equal number of AON LLC Common Units and shares of New AON Class B common stock (“New AON Class B Common Stock”), which together are exchangeable into shares of New AON Class A Common Stock (together with the New AON Class B Common Stock, the “New AON Common Stock”); (iii) New AON amended and restated its charter (the “Charter”) to provide for (a) the conversion of all existing shares of DTOC Class B common stock into shares of New AON Class A Common Stock on a one-to-one basis, (b) amendment of the terms of New AON Class B Common Stock to provide holders voting rights but no economic rights and (c) designation of a new series of New AON preferred stock as Series A convertible preferred stock (the “New AON Series A Preferred Stock” or “Series A Preferred Stock") with such rights and preferences as provided for in the certificate of designation of the New Aon Series A Preferred Stock (the “New AON Series A Certificate of Designation”); and (iv) among other things, (a) AON LLC issued common units to New AON in exchange for a combination of cash and shares of New AON Class B Common Stock and warrants to acquire shares of New AON Class B Common Stock (the “Class B Prefunded Warrants”), (b) New AON was admitted as a member of AON LLC, (c) AON LLC distributed shares of New AON Class B common stock or Class B Prefunded Warrants, as applicable, to AON LLC equity holders, (d) New AON reserved a specified number of additional shares of New AON Class A Common Stock after the Closing for issuance to eligible participants, (e) Merger Sub merged with and into the AON Class C Preferred Investor whereby the separate existence of Merger Sub ceased and New AON issued a number of shares of New AON Series A Preferred Stock equal to the number of AON LLC Series A preferred units held by the AON Class C Preferred Investor to AEA Growth Management LP, the parent of AON Class C Preferred Investor (“AEA Growth”) in exchange for all the shares of common stock held by AEA Growth in the AON Class C Preferred Investor (the “First Step”), (f) promptly after the First Step, the AON Class C Preferred Investor merged with and into New AON whereby the separate existence of the
40

AON Class C Preferred Investor ceased and New AON held all the AON LLC Series A preferred units and (g) from and after the Closing (but subject to lock-up restrictions), the AON LLC common equity holders (other than New AON), referred to herein as “Legacy AON Stockholders” (former AON LLC Class A, Class A-1, and Class B unit holders), will have the right (but not the obligation) to exchange AON LLC Common Units together with an equal number of shares of New AON Class B Common Stock (whether held directly or indirectly through Class B Prefunded Warrants) for shares of New AON Class A Common Stock.

In addition, in connection with the Closing, DTOC completed the offer to the holders of AON LLC Class B-1 units to exchange their AON LLC Class B-1 units for such number of newly issued shares of New AON Class A Common Stock equal to the ratio set forth in the Business Combination Agreement (such offer, the “Exchange Offer”). DTOC and AON LLC solicited consents from the holders of AON LLC Class B-1 units to make certain amendments to the terms of the awards and the unit grant agreements pursuant to which the AON LLC Class B-1 units were granted, which provided for the automatic exchange, as of immediately prior to the adoption of the Amended and Restated AON LLC Agreement, of all outstanding AON LLC Class B-1 units into shares of New AON Class A Common Stock (collectively, the “Proposed Amendments”). The requisite number of holders of Class B-1 units provided their consent to the Proposed Amendments, and as a result, in connection with the Closing, all AON LLC Class B-1 units were exchanged for an aggregate of 1,047,343 shares of New AON Class A Common Stock.

Key Factors Affecting Performance & Non-GAAP Measures
Factors Affecting Our Revenues
There are many factors that drive patient service revenues; however, we focus on certain key metrics such as:
Total patient encounters which include initial consultations and treatments, new patient encounters, recurring patient encounters and treatments, and cancer vs non cancer patients.
Patient referrals which are also an important driver of patient service revenue; we manage the referral pipeline locally through the coordinated efforts of our physician liaisons working with our physicians to market our practices by visiting referral sources such as, primary care providers and other medical specialties.
Factors Affecting Our Operating Costs
Operating costs are primarily dependent upon factors such as:
The cost of prescription drugs used in our treatment plans which include both intravenous and oral oncolytics. The management of these costs are a critical component of our business as it is our single largest expense. We manage
41

this cost by strategic volume purchases and continuously evaluating the most clinically effective drug for cancer type through our Pharmaceutical and Therapeutics Committee.
Clinical compensation and benefits, including non-medical personnel, represent our second largest operating expense. These costs are impacted by both micro and macro-economic factors as well as local competition for personnel that could impact costs associated with personnel. In particular, in all of our markets, we have seen significant increases in compensation for qualified nursing resources. We continuously monitor wages period over period to mitigate the impact of variations in industry and macro-economic labor conditions.
We lease all of our facilities, therefore real-estate costs are a significant component of our operating costs. We continuously monitor local and national real estate conditions to actively manage our exposure to fluctuating occupancy costs.
Key Non-GAAP Financial Measures We Use to Evaluate Our Performance
Adjusted EBITDA
This filing includes the non-GAAP financial measure “Adjusted EBITDA”. Management views this metric as a useful way to look at the performance of our operations between periods and to exclude decisions on capital investment and financing that might otherwise impact the review of profitability of the business based on present market conditions. Management believes 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.
Adjusted EBITDA is defined as net income prior to interest income, interest expense, income taxes, and depreciation and amortization, as adjusted to add back certain other non-cash charges that we may record each year, such as stock-compensation expense, as well as non-recurring charges such as expenses incurred related to major operational transitions and transaction costs. We believe these expenses and non-recurring charges are not considered an indicator of ongoing company performance. The measures are used as a supplement to GAAP results in evaluating certain aspects of our business, as described below. We believe Adjusted EBITDA is useful to investors in evaluating our performance because the measure considers the performance of our operations, excluding decisions made with respect to capital investment, financing, and other non-recurring charges as outlined above.
The Company includes Adjusted EBITDA because it is an important measure upon which our management uses to assess the results of operations, to evaluate factors and trends affecting the business, and to plan and budget future periods. 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 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, and not to rely on any single financial measure. Adjusted EBITDA should not be considered as an alternative to net income as an indicator of our performance or as an alternative to any other measure prescribed by GAAP as there are limitations to using such non-GAAP measures. We compensate for these limitations by providing disclosure of the differences between Adjusted EBITDA and GAAP results, including providing a reconciliation to GAAP results, to enable investors to perform their own analysis of our operating results.
Components of Results of Operations
Patient Service Revenue, net
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, including managed Medicare and Medicaid; and (v) individual patients.
The primary elements of patient service revenue are from fee for service (“FFS”) revenue which includes revenue from required patient infusion and injection treatments, as well as oral prescription drugs. FFS revenue comprise revenues in which we bill and collect for medical services rendered by our physicians or nurse practitioners including office visits and consults. FFS revenue also includes infusion therapies and treatment. FFS revenue consists of fees for medical services provided to patients. Payments for services provided are generally less than billed charges. The Company records revenue
42

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 encounter, proper medical coding of the charts, and the verification and authorization of each patient’s eligibility at the time services are rendered as to the payor(s) responsible for payment of such services.
Oral prescription drugs comprise revenues from prescriptions written by our doctors to their patients which are dispensed directly by AON’s specialty pharmacy. Revenue for the oral prescription 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 adherence and other metrics. DIR fees may be significant and may be assessed in the periods after payments are received against future payments. The Company recognizes revenue, net of estimated DIR fees, at the time the patient takes possession of the oral drug.
Other Revenue
Other revenue is primarily generated from service arrangements with various hospitals systems and data contracts as well as through clinical trials.
Cost of Revenue
Cost of services primarily includes chemotherapy drug costs, clinician salaries and benefits, medical supplies, and clinical occupancy costs. Clinicians include oncologists, advanced practice providers such as physician assistants and nurse practitioners, and registered nurses. Specialty pharmacy costs primarily include the cost of oral medications dispensed from the specialty pharmacy including overhead costs for running a free-standing pharmacy and shipping costs to patients.
General and administrative
Our general and administrative expenses include corporate occupancy costs, technology infrastructure, operations, clinical and quality support, finance, legal, human resources, and business development. Depreciation and amortization expenses are also included in general and administrative expenses. The Company expects its general and administrative expenses to increase over time following the consummation of the Business Combination due to the additional legal, accounting, insurance, investor relations and other costs that the Company will incur as a public company, as well as other costs associated with continuing to grow the business. While we expect general and administrative expenses to increase in the foreseeable future, such expenses on average are expected to decrease as a percentage of revenue over the long term, as the company continues to scale its operations.

Transaction Expenses
Transaction expenses consist of legal services, professional fees and other due diligence expenses that were incurred in connection with the Business Combination. These transaction expenses are considered non-recurring and as a result are included as an add-back in the Company’s Adjusted EBITDA calculation.

For the three months ended March 31, 2024 and 2023 revenue increased $60.6 million, or 20.0%, primarily due to a $59.7 million increase in patient service revenue and a $0.9 million increase in other revenue.
43

Patient service revenue, net
For the three months ended March 31, 2024 and 2023 the $59.7 million increase in revenue is largely attributable to an increased revenue per encounter of 12.8% driving $41.0 million of the revenue increase. $18.7 million of increase in patient service revenue was due to increase of patient encounters of 7.1% seen within the period. This revenue growth was constrained in part by approximately $4.1 million of incremental implicit price concessions associated with accounts receivable in our legacy billing system as the Company transitioned its billing and collection efforts to a new billing system in the fourth quarter of 2023.
Other revenue
For the three months ended March 31, 2024 and 2023 other revenue increased $0.9 million due to an increase in service arrangements and data contracts.

For the three months ended March 31, 2024 and 2023, operating expenses increased $79.4 million, or 26.1%, due to a $76.4 million increase in cost of revenue, and a $4.6 million increase in general and administrative expenses offset by a $1.6 million decrease in transaction expenses.
Cost of revenue
For the three months ended March 31, 2024 and 2023, cost of revenue increased $76.4 million which was primarily driven by drug and medical supply costs, due to both increased patient encounters and cost per encounter. The volume of patient encounters at our practices increased cost of revenue by $14.9 million, and the cost per encounter drove a $42.8 million increase. The increased cost of patient encounters was driven by a combination of higher drug and supply costs as well as the drug and service mix patients required. In March 2024, the Company issued Restricted Stock Units (“RSUs”) under the 2023 Equity Incentive Plan to employees of the Company with various vesting periods including RSUs that vest immediately, over a period of one year, and over a period of two years. The Company recognized $13.3 million of equity-based compensation expense associated with the March 2024 grant of RSUs, substantially all of which was related to RSUs that vested immediately upon grant. There was no stock-based compensation expense recognized during the three months ended March 31, 2023. Refer to Note 12, Equity-Based Compensation, for further discussion.
General and administrative expense
For the three months ended March 31, 2024 and 2023, the $4.6 million increase in general and administrative expenses was driven by a $1.1 million increase in revenue cycle costs associated with the Company’s growth and optimization of our revenue cycle function as well as $0.9 million of increase seen in computer expense as a result of Company’s AthenaIDX RCM conversion and dual RCM costs within the quarter. The company saw an increase of $1.4 million in insurance and accounting fees as a result of being publicly traded as well as $1.5 million increase in operating costs related to legal costs, office expenses, contract labor, licenses, and travel expenses relative to Company growth.
Transaction expense
For the three months ended March 31, 2024 and 2023, the Company saw a $1.6 million decrease in transaction expenses driven by the legal, accounting, and consulting fees incurred by the Company due to the Business Combination that closed in September of 2023.

The change to the income tax provision for the three months ended March 31, 2024 compared to the income tax provision for the three months ended March 31, 2023 was primarily a result of the transaction closing on September 20, 2023, resulting in a portion of the Company's consolidated pre-tax earnings, which were previously not subject to income taxes, flowing into a taxable corporation included in the Company's post transaction structure. As of December 31, 2023, the Company recognized a deferred tax asset related to its investment in the American Oncology Network, LLC partnership. As of March 31, 2024, the Company updated its valuation allowance assessment based on new factors including its year-to-date loss and forecasted loss at the American Oncology Network, LLC partnership legal entity. Based on its updated valuation allowance assessment, the Company recorded a discrete valuation allowance against its investment in partnership deferred tax asset during the three months ending March 31, 2024.

Liquidity and Capital Resources 
General
To date, the Company has financed its operations principally through the issuance of membership units and long-term debt, and to a lesser extent, cash flows from operations. As discussed below, on June 7, 2023, the Company entered into an agreement to issue Class C Preferred Units for net proceeds of approximately $64.5 million. As of March 31, 2024, the Company had $74.9 million of cash and cash equivalents, $30.1 million of short-term marketable securities, $80.9 million in outstanding long-term indebtedness, and $1.0 million of availability under its PNC Line of Credit. 
The Company may incur operating losses and generate negative cash flows from operations for the foreseeable future due to the investments management intends to continue making 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, operating cash flows, and availability under PNC Facility will be sufficient to fund the Company’s operating and capital needs for at least the next 12 months. The Company’s actual results may vary due to, and its future capital requirements will depend on, many factors, including its organic growth rate and the timing and extent of acquisitions of new clinics and expansion into new markets. The Company may in the future enter into arrangements to acquire or invest in complementary businesses. 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. 

Reverse Recapitalization

The Company closed the Business Combination on September 20, 2023 (“the Closing” or the “Closing Date”). As of the Closing, the Company received $1.4 million of the remaining cash held in the Trust Account after all redemptions. On the Closing Date, the Company paid $7.1 million of DTOC transaction expenses incurred as a result of the Business Combination. The Company assumed an additional $6.1 million in liabilities, of which $3.4 million were related to an excise tax and $2.7 million related to unpaid transaction expenses incurred by DTOC as a result of the Business Combination.
46

Significant Financing Transactions
2022 Debt Financing Activity
In 2022, the Company amended the PNC Facility and Line of Credit agreements. The primary changes included an increase of the Facility limit from $75.0 million to $125.0 million, a decrease of the PNC Line of Credit amount from $5.0 million to $1.0 million, interest charges to be calculated based on the Bloomberg Short-Term Bank Yield Index plus 1.65% and certain financial covenants. As part of the amendments, the Company drew an additional $16.3 million in proceeds under the Facility. 
The total amount outstanding under the PNC Facility as of December 31, 2023 was $81.3 million at an interest rate of 7.19%. No amounts were drawn down on the PNC Line of Credit as of December 31, 2023.
2023 Sale of Class C Equity
On April 27, 2023, AON LLC and the AON Class C Preferred Investor entered into a Unit Purchase Agreement, which they subsequently amended and restated on June 7, 2023 (as amended, the “Unit Purchase Agreement”), which provides for an investment of at least $65.0 million with an option to increase the investment to $75.0 million in connection with the issuance of AON Class C Convertible Preferred Units (“AON Class C Units”) to the AON Class C Preferred Investor.
Pursuant to the Unit Purchase Agreement, on June 7, 2023, the AON Class C Preferred Investor purchased, and AON LLC issued and sold to the AON Class C Preferred Investor, 2,459 AON Class C Units at an aggregate purchase price of $65.0 million. Under the Unit Purchase Agreement, the AON Class C Preferred Investor has an option to purchase an additional 378 AON LLC Class C Units until the closing of the Business Combination (the “Closing”), at a purchase price of $26,432 per Unit. This option was not exercised and expired as of the Closing of the Business Combination. In connection with the Class C Unit sale, AON LLC amended and restated its operating agreement, to among other things, authorize 2,837 AON LLC Class C Units of which 2,459 were outstanding as of June 30, 2023 to the AON Class C Preferred Investor. The AON LLC Class C Units were reclassified into AON LLC Series A Preferred Units as of September 20, 2023, the Closing Date. Concurrently, New AON issued a number of shares of New AON Series A Preferred Stock equal to the number of AON Series A Preferred Units held by the AON Class C Preferred Investor to AEA Growth Management LP, the parent of AON Class C Preferred Investor (“AEA Growth”) in exchange for all the shares of common stock held by AEA Growth in the AON Class C Preferred Investor. Promptly after the First Step, the AON Class C Preferred Investor merged with and into New AON whereby the separate existence of the AON Class C Preferred Investor ceased and New AON held all the AON Series A Preferred Units.
2023 Debt Financing Activity
On June 30, 2023, AON entered into Amendment No. 7 to its PNC Loan Facility which primarily extended the maturity date of the Facility from April 30, 2024 to June 30, 2026.
On December 31, 2023, AON entered into Amendment No. 3 to its Line of Credit agreement to modify certain definitions such as “change in control”. In addition, this also amended certain debt covenants, such as the EBITDA thresholds.
2024 Debt Financing Activity
On January 16, 2024, AON entered into Amendment 8 to its PNC Loan Facility in order to modify the agreement to reflect that transfers of AON LLC units between AON LLC members to AON Inc. or the holder of a majority of AON Inc.’s Series A Preferred Stock, do not trigger a change of control, as defined therein, consistent with the intention of the parties to the PNC Loan Facility. In addition, Amendment 8 also amended the delinquency ratio threshold used to calculate certain debt covenants.
Cash Flows

Cash flows from operating activities

The primary sources and uses of our operating cash flow are operating income or operating losses, net of any non-cash items such as stock-based compensation, and depreciation and amortization. The timing of collections of accounts receivable and the payment of accounts payable, and other working capital items can also impact and cause fluctuations in our operating cash flow. Cash provided by operating activities increased by $45.5 million during the three-month period ended March 31, 2024 compared to the three month period ended March 31, 2023, primarily due to:

The comparative provision of cash of $56.4 million from accounts payable, primarily associated with the timing of $48.3 million of vendor payments for drug purchases during the first quarter of 2024 that were deferred until the second quarter of 2024.

The comparative provision of cash of $13.6 million associated with the timing of collections of patient accounts receivable, net.

An increase in loss from operations during the three month period ended March 31, 2024, net of changes in non-cash items such as stock compensation, as well as the comparative usage of cash related to other working capital items.
Cash flows from investing activities
Net cash provided by investing activities was $1.5 million for the three months ended March 31, 2024 compared to $2.6 million used in for the comparable period for 2023. The increase in cash provided period over period was primarily attributable to the following:
Purchases of marketable securities for the three months ended March 31, 2024 of $7.1 million were offset by sales of marketable securities of $12.6 million. Purchases of marketable securities for the three months ended March 31, 2023 were $1.4 million offset by sales of $1.4 million during this period. This difference resulted in approximately a $5.6 million increase in cash provided between periods.
The $1.4 million increase in purchases of property and equipment during the three months ended March 31, 2024, compared to 2023 further increased the cash provided between periods.
Cash flows from financing activities
Net cash used in financing activities was $0.3 million for the three months ended March 31, 2024 compared to net cash used in financing activities of $0.1 million for the comparable period for 2023.
Off Balance Sheet Arrangements
As of the date of this Quarterly Report on Form 10-Q, AON does not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors. The term “off-balance sheet arrangement” generally means any transaction, agreement or other contractual arrangement to which an entity unconsolidated with AON is a party, under which it has any obligation arising under a guarantee contract, derivative instrument or variable interest or a retained or contingent interest in assets transferred to such entity or similar arrangement that serves as credit, liquidity or market risk support for such assets.
AON does not engage in off-balance sheet financing arrangements.

Cash outflows related to certain vendor contracts with committed expenditures are expected to total approximately $1.6 million. The timing of the expenditures is as follows: $1.6 million in 2024.
The Company does not have any significant supply or other arrangements which result in material cash requirements other than as described above.
Critical Accounting Policies and Estimates
The accompanying consolidated financial statements have been prepared in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Revenue Recognition
Revenue is recognized under Accounting Standards Update (“ASU”) 2014-09 Revenue from Contracts with Customers (“Topic 606”). The Company determines the transaction price based upon standard charges for goods and services with anticipated consideration due from patients, third-party payors (including health insurers and government agencies) and others. The Company’s revenue is primarily derived from patient service revenues, which encompass oncology services provided during patient encounters and shipments of pharmacy prescriptions. Performance obligations for the Company’s services provided to patients and most procedures, are satisfied over the time of visit which is the same day services are performed. Performance obligations relating to pharmacy revenue are considered fully satisfied at a point in time upon the customer receiving delivery of the prescription. Accordingly, the Company does not anticipate a significant amount of revenue from performance obligations satisfied (or partially satisfied) in previous periods.
As services are performed and prescriptions are shipped, timely billing occurs for services rendered and prescriptions shipped less discounts provided to uninsured patients and contractual adjustments to third-party payors based upon prospectively determined rates and discounted charges. Payment is requested at the time of service for self-paying patients and for patients covered by third-party payors that are responsible for paying deductibles and coinsurance.
The Company monitors revenue and receivables to prepare estimated contractual allowances for the anticipated differences between billed and reimbursed amounts. Payments from third-party payors and Government programs including Medicare and Medicaid may be subject to audit and other retrospective adjustments. Such amounts are considered on an estimated basis when net patient revenue is recorded and are adjusted as final adjustments are determined.
The Company has a system and estimation process for recording Medicare net patient service revenue and estimated recoupments as it relates to value-based care (“VBC”) revenue included in patient service revenue on the Consolidated Statements of Operations and Comprehensive Income (Loss). The Company’s VBC revenue is primarily generated through its participation in the Enhancing Oncology Model (“EOM”) which is an episode-based payment model to promote high-quality cancer care. Participants enter six-month episode periods, and the Company bills a monthly fee during the six-month period based on a fixed rate per participant per month and the total number of participants. Certain quality and compliance metrics are tracked as part of the program and submitted to CMS at the end of the episode period which may result in recoupment of funds. The Company estimates the recoupment amount by developing a recoupment percentage for each period based on historical known recoupment from CMS and applies the recoupment percentage against total fees for
49

the period. Based on the estimate, the Company accrues a liability representing the expected final recoupments based on historical settlement trends.
Accounts Receivable
Accounts receivable from patients are carried at the original charge for the services provided, and an adjustment is made to the receivable in a contra account based on the historical collection rate for the provider and payor combination. This adjustment takes into consideration any allowance for doubtful accounts. Management determines the allowance for uncollectible accounts based on historical experience.
Business Combinations
The Company evaluates acquired practices in accordance with ASU 2017-01, Business Combinations (Topic 805) — Clarifying the Definition of a Business. This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Because substantially all of the value of each acquired practice did not relate to a similar group of assets and as each acquired practice contained both inputs and processes necessary to provide economic benefits to the Company, it was determined that each acquisition represents a business combination. Therefore, the transactions have been accounted for using the acquisition method of accounting, which requires, with limited exceptions, that assets acquired, and liabilities assumed be recognized at their estimated fair values as of the acquisition date. Any excess of the consideration transferred over the estimated fair values of the net assets acquired is recorded as goodwill. Transaction costs related to business combinations are expensed in the period in which they are incurred.
Professional Liability
The Company maintains an insurance policy for exposure to professional malpractice insurance risk beyond selected retention levels. Reserves are established for estimates of the loss that will ultimately be incurred on claims that have been reported but not paid and claims that have been incurred but not reported. These reserves are established based on consultation with a third-party actuary. The actuarial valuations consider a number of factors, including historical claims payment patterns, changes in case reserves and the assumed rate of increase in healthcare costs. Management believes the use of actuarial methods to account for these reserves provides a consistent and effective way to measure these subjective accruals. However, due to the sensitive nature of this estimation technique, recorded reserves could differ from ultimate costs related to these claims due to changes in claims reporting, claims payment and settlement practices and differences in assumed future cost increases. Accrued unpaid claims and expenses that are expected to be paid within the next twelve months are classified as current liabilities and included in accrued other. All other accrued unpaid claims and expenses are classified as long-term liabilities and included in other long-term liabilities. Insurance recoveries associated with the unpaid claims are classified as long-term assets included in other assets.

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
Certain of AON’s outstanding indebtedness bears interest at a floating rate. As a result, AON may be exposed to fluctuations in interest rates to the extent of its borrowings under these arrangements. AON does not currently engage in any hedging or derivative instruments to attempt to offset this risk. Based on the total amount of variable debt outstanding as of March 31, 2024, if the Bloomberg Short-Term Bank Yield Index increased by 1.0% due to normal market conditions, AON’s interest expense will increase by approximately $0.8 million per annum.
AON had $81.3 million of borrowings under loans with variable rates as of March 31, 2024.
Inflation Risk
The healthcare industry is very labor intensive and salaries and benefits are subject to inflationary pressures, as are drug and medical supplies costs, medical equipment and other costs. The nationwide shortage of nurses and other clinical staff and support personnel has been a significant operating issue facing us and other healthcare providers. In particular, like others in the healthcare industry, we have experienced a shortage of nurses and other clinical staff and support
50

personnel in certain geographic areas, which was largely driven by the COVID-19 pandemic. Nationally, the increase demand for healthcare workers has in some regions, required us to offer one-time retention bonuses, pay premium wages above standard compensation for essential workers, and even utilize higher cost temporary labor. This staffing shortage may require us to further enhance wages and benefits to recruit and retain nurses and other clinical staff and support personnel or require us to hire expensive temporary personnel. We have also experienced cost increases related to the procurement of medical supplies and equipment as well as construction of new facilities and additional capacity added to existing facilities. Our ability to pass on increased costs associated with providing healthcare to Medicare and Medicaid patients is limited due to various federal, state and local laws which have been enacted that, in certain cases, limit our ability to increase prices.
We minimize the impact of inflation on our labor, drug, and supply costs primarily through maintaining strong relationship with our suppliers and GPO and renegotiated contracts with our payors. In addition, AOP has a Pharmacy and Therapeutics Committee (“P&T Committee”) that meets biweekly to evaluate and modify the preferred drug formulary. The P&T Committee considers the following in its formulary recommendations: 1) evidence-based research demonstrating favorable clinical outcomes of such treatment; 2) potential adverse events or side effects of such treatment; and 3) cost of such treatment to the applicable stakeholder (patient and payor).

Item 4. Controls and Procedures
Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2024. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company on the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including, our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgement in designing and evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2024, our Chief Executive Officer and Chief Financial Officer concluded that, as a result of material weaknesses identified in our internal control over financial reporting, as previously disclosed in our Annual Report on Form 10-K, filed with the SEC on March 28, 2024, our disclosure controls and procedures were not effective as of March 31, 2024. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting as defined under the Exchange Act and by the Public Company Accounting Oversight Board (United States), 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. We are in the process of implementing measures designed to improve our internal control over financial reporting to remediate these material weaknesses.
Changes in Internal Control

There has been no change in our internal control over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act during our most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
