DFP Healthcare Acquisitions Corp. ANNOUNCES PROPOSED BUSINESS COMBINATION WITH the oncology institute

The Oncology Institute is the U.S. Market Leader in Value-Based Oncology Care

New York, NY and Los Angeles, CA – June 28, 2021 – DFP Healthcare Acquisitions Corp (“DFP”) (NASDAQ: DFPH, DFPHW), a special purpose acquisition company sponsored by an affiliate of Deerfield Management Company, L.P. (“Deerfield”) and Richard Barasch, a veteran healthcare public company executive and investor, announced today that it has entered into a definitive agreement for a business combination with The Oncology Institute ( “TOI” or “The Company”), the U.S. market leader in providing value-based oncology care. Following the business combination, DFP expects to be renamed The Oncology Institute and will remain listed on the NASDAQ stock market under new ticker symbol “TOI”.

The transaction values the combined company at a pro forma enterprise value of approximately $842 million and implies a multiple of 2.4x estimated 2022 revenue. The current equity holders of The Oncology Institute, which include Management, Havencrest Capital Management, M33 Growth, and ROCA Partners, will be entitled to receive an additional earn out payment of up to 12.5 million shares of The Oncology Institute common stock.

In addition to the approximately $230 million held in the DFP Trust Account, premier healthcare investors, including Fidelity Management & Research Company LLC, Deerfield Management Company, L.P. and Redmile Group, LLC have committed to purchase $275 million of shares of common stock of the Company at $10.00 per share through a private placement in public entity (a “PIPE”).

Assuming no redemptions of DFP public shares, the current equity holders of The Oncology Institute will collectively own 48%, Deerfield will own approximately 14%, other DFP stockholders (including other PIPE investors) will own 33%, and DFP’s sponsor will own 5% respectively of the approximately 106 million issued and outstanding shares of common stock of The Oncology Institute immediately following the closing.

DFP estimates that, assuming no redemptions of DFP shares, the Company will have an initial market capitalization of approximately $1.06 billion, with approximately $225 million of cash on the balance sheet and a strong growth trajectory. The Oncology Institute expects to use this capital to accelerate its de novo and acquisition-driven growth initiatives.

Please refer to the investor presentation furnished with DFP’s Current Report on Form 8-K for details on the pro-forma financials of the Company and its Non-GAAP Financial Measures.

“TOI is elevating the standard of care in community oncology. By focusing on individualized care plans, evidence-based medicine, and great symptom control, TOI patients can achieve better outcomes with reduced financial burden. The rising cost and poor coordination of oncology care in the United States is driven by several factors, including misalignment between physicians and payors, complex and variable clinical pathways, and the high cost of cancer therapies,” said Brad Hively, CEO of The Oncology Institute. “Traditional fee for service payment models emphasize quantity over quality of care, without considering patient wellness and satisfaction as metrics of success. We are committed to applying the principles of value-based care to simultaneously enhance quality and manage costs. For more than 14 years, The Oncology Institute has played a significant role in the lives of cancer patients by providing accessible, high-quality medical care. Our proposed combination with DFP brings us significantly closer to expanding our presence across the United States and advancing our efforts to rebuild the nation’s healthcare system.”

“The Oncology Institute is disrupting the status quo in cancer care, and we are pleased to assist them in continuing their mission of broadening access to high quality, value-based care.” said Mr. Barasch. “Brad and his team have created a scalable, replicable model with difficult-to-duplicate capabilities that facilitate rapid expansion. We believe that their high-touch, data-driven approach to cancer care represents the model of the future. This business combination will create a well-capitalized company that is poised to expand organically, through accretive M&A activity, and via strategic payor relationships.”

The business combination, which has been approved by the board of directors of DFP and The Oncology Institute, is expected to close in the 3^rd or 4^th quarter of 2021, subject to customary conditions, including the approval by DFP stockholders.

A more detailed description of the transaction terms and a copy of the business combination agreement will be included in a current report on Form 8-K to be filed by DFP with the United States Securities & Exchange Commission (“SEC”). DFP will file a proxy statement with the SEC in connection with the transaction.

This press release includes certain statements that are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding projections, estimates and forecasts of revenue and other financial and performance metrics and projections of market opportunity and expectations, the expectation that the Company’s common stock will be listed on Nasdaq, and the anticipated closing date of the proposed business combination. These statements are based on various assumptions and on the current expectations of DFP and The Oncology Institute and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of DFP and The Oncology Institute. These forward-looking statements are subject to a number of risks and uncertainties, including the outcome of judicial and administrative proceedings to which The Oncology Institute may become a party or governmental investigations to which The Oncology Institute may become subject that could interrupt or limit The Oncology Institute’s operations, result in adverse judgments, settlements or fines and create negative publicity; changes in The Oncology Institute’s clients’ preferences, prospects and the competitive conditions prevailing in the healthcare sector; the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the stockholders of DFP and/or the equity holders of The Oncology Institute for the proposed business combination is not obtained; failure to meet stock exchange listing standards following the consummation of the business combination; costs related to the business combination; failure to realize the anticipated benefits of the proposed business combination, including as a result of a delay in consummating the proposed business combination or a delay or difficulty in integrating the businesses of DFP and The Oncology Institute; the amount of redemption requests made by DFP’s stockholders; the impact of COVID-19 on the combined company’s business and/or the ability of the parties to complete the proposed Business Combination; those factors discussed in DFP’s registration statement on Form S-1, which was initially filed with the SEC on February 21, 2020, under the heading “Risk Factors,” and other documents of DFP filed, or to be filed, with the SEC. If the risks materialize or assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither DFP nor The Oncology Institute presently know or that DFP and The Oncology Institute currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect DFP’s and The Oncology Institute’s expectations, plans or forecasts of future events and views as of the date of this press release. DFP and The Oncology Institute anticipate that subsequent events and developments will cause DFP’s and The Oncology Institute’s assessments to change. DFP and The Oncology Institute do not undertake any obligation to update any of these forward-looking statements. These forward-looking statements should not be relied upon as representing DFP’s and The Oncology Institute’s assessments as of any date subsequent to the date of this press release. Accordingly, undue reliance should not be placed upon the forward-looking statements.

The financial information and data contained in this press release is unaudited and does not conform to Regulation S-X. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement or registration statement to be filed by DFP or The Oncology Institute with the SEC. Some of the financial information and data contained in this press release, such as adjusted EBITDA, has not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). A reconciliation of certain of these non-GAAP financial measures to their most comparable GAAP measure is set forth in a table in the investor presentation.

DFP and The Oncology Institute believe these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to The Oncology Institute’s financial condition and results of operations. DFP and The Oncology Institute believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing The Oncology Institute’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Management of The Oncology Institute does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in The Oncology Institute’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. You should review The Oncology Institute audited financial statements, which will be presented in DFP’s proxy statement to be filed with the SEC, and not rely on any single financial measure to evaluate DFP and The Oncology Institute’s business.

Use of Projections: This presentation contains projected financial information with respect to TOI, including revenue, gross profit, gross margin, Adjusted EBITDA and Adjusted EBITDA margin. Such projected financial information constitutes forward- looking information, is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the projected financial information. See “Forward-Looking Statements” above and the Risk Factors included at the end of this presentation. Actual results may differ materially from the results contemplated by the projected financial information contained in this presentation, and the inclusion of such information in this presentation should not be regarded as a representation by any person that the results reflected in such projections will be achieved.

Financial Information; Non-GAAP Financial Measures: The financial information and data contained in this presentation is unaudited and does not conform to the requirements of Regulation S-X. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement, registration statement or prospectus to be filed by the SPAC with the SEC. In addition, the historical financial information included herein is preliminary and subject to change, including in connection with the audit of the financial statements, which has not been completed. Some of the financial information and data contained in this presentation, such as Adjusted EBITDA and Adjusted EBITDA margin, have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). The Company believes that the use of Adjusted EBITDA provides an additional tool to assess operational performance and trends in, and in comparing our financial measures with, other similar companies, many of which present similar non-GAAP financial measures to investors. TOI’s non-GAAP financial measures may be different from non-GAAP financial measures used by other companies. The presentation of non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial measures determined in accordance with GAAP. The principal limitation of Adjusted EBITDA is that it excludes significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. A reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure for full years 2021 – 2024 cannot be provided without unreasonable effort because of the inherent difficulty of accurately forecasting the occurrence and financial impact of the various adjusting items necessary for such reconciliations that have not yet occurred, are out of the Company’s control or cannot be reasonably predicted. For the same reasons, the Company is unable to provide probable significance of the unavailable information, which could be material to future results. Because of the limitations of non-GAAP financial measures, you should consider the non-GAAP financial measures presented in this presentation in conjunction with TOI’s financial statements and the related notes thereto. 2

Summary Risk Factors

Certain Risks Related to the Oncology Institute All references to “TOI,” “we,” “us,” “our” or the “Company” refer to the business of TOI Parent, Inc. and its affiliates. The risks presented below are certain of the general risks related to the business of the Company, and such list is not exhaustive. The list below has been prepared solely for purposes of the private placement transaction, and solely for potential private placement investors, and not for any other purpose. Accordingly, the list below is qualified in its entirety by disclosures contained in future documents filed or furnished with the United States Securities and Exchange Commission (“SEC”), including the documents filed or furnished by the Company and/or the special purpose acquisition company (the “SPAC”) in connection with the proposed business transaction. The risks presented in such filings will be consistent with those that would be required for a public company in their SEC filings, including with respect to the business and securities of the Company and the SPAC and the proposed business transaction between the Company and the SPAC, and may differ significantly from and be more extensive than those presented below. • Our growth strategy depends on our ability to build or acquire new clinics to service our contracts and treat our patients, and if we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of service and patient satisfaction or adequately address competitive challenges. • Our services are concentrated in certain geographic areas and populations exposing us to unfavorable changes in local benefit costs, reimbursement rates, competition and economic conditions. • We primarily depend on reimbursement from third-party payors, as well as payments by individuals, which could lead to delays, denials, or uncertainties in the reimbursement process. • With many of our value-based agreements, we assume the risk that the cost of providing services will exceed our compensation. • As oncology costs rise, if we do not accurately predict the cost to deliver care, some of our value-based agreements could become less profitable, or unprofitable. • Renegotiation, non-renewal or termination of our third-party payor contracts, including capitation agreements with health plans, could have a material adverse effect on our business, results operations, financial condition and cash flows. • We derive a significant portion of our sales from a limited number of health insurance and medical group companies. Those health insurance and medical group companies could take action to remove, exclude, delay, or otherwise prevent our inclusion in their provider networks. • We derive a significant portion of our sales from prescription drug sales reimbursed by a limited number of pharmacy benefit management companies. Those pharmacy benefit management companies could take action to remove, exclude, delay or otherwise prevent our inclusion in their provider networks. • We cannot predict the effect that health care reform and other changes in government programs may have on our business, financial condition or results of operations. • Reductions in Medicare reimbursement rates or changes in the rules governing the Medicare program could have a material adverse effect on our financial condition and results of operations • Competition for physicians and clinical personnel, including nurses, shortages of qualified personnel or other factors could increase our labor costs and adversely affect our revenue, growth rate, profitability and cash flows. • We must attract and retain highly qualified physicians, medical professionals and other personnel in order to execute our growth plan. • If we are unable to provide consistently high quality of care, our business will be adversely impacted. • We may become subject to medical liability claims, which could cause us to incur significant expenses, may require us to pay significant damages if not covered by insurance, and could harm our business. • If certain of our suppliers do not meet our needs, if there are material price increases on supplies, if we are not reimbursed or adequately reimbursed for drugs we purchase or if we are unable to effectively access new technology or superior products, it could negatively impact our ability to effectively provide the services we offer and could have a material adverse effect on our business, results of operations, financial condition and cash flows. • If we are unable to protect the confidentiality of our trade secrets, know-how and other proprietary and internally developed information, the value of our technology could be adversely affected. • A pandemic, epidemic or outbreak of an infectious disease in the United States or worldwide, including the outbreak of the novel strain of coronavirus disease, COVID-19, could adversely affect our business, financial condition, results of operations and growth. 43

Certain Risks Related to the Oncology Institute (Cont'd) • With respect to Innovative Clinical Research Institute, if we fail to perform our clinical trial services in accordance with contractual requirements, government regulations and ethical considerations, we could be subject to significant costs or liability and our reputation could be adversely affected. • Actual or perceived failures to comply with applicable data protection, privacy and security, advertising and consumer protection laws, regulations, standards and other requirements could adversely affect our business, financial condition and results of operations. • We depend on our information technology systems, and those of our third-party vendors, contractors and consultants, and any failure or significant disruptions of these systems, security breaches or loss of data could materially adversely affect our business, financial condition and results of operations. • Our centers and affiliated physician practices providing professional services at such centers may become subject to medical liability claims, which could have a material adverse impact on our business. • Our centers and affiliated physician practices may be subject to third-party payor audits, which, if adversely determined against us or affiliated physician practices, may have a material effect on our results of operations and financial condition. • Third-party payors and other entities, such as pharmacy benefit managers, continue to take action to manage and/or control the utilization and cost of drugs and medical devices. • We could be adversely affected by increases in the cost to procure drugs. • We could be adversely affected by drug shortages that prevent us from providing certain treatments. • We are subject to extensive fraud, waste, and abuse laws that may give rise to federal and state audits, investigations, lawsuits and claims against us, the outcome of which may have a material adverse effect on our business, financial condition, cash flows, or results of operations. • Laws regulating the corporate practice of medicine and fee-splitting with physicians could restrict the manner in which we are permitted to conduct our business, and the failure to comply with such laws could subject us to penalties or require a restructuring of our business. • We are dependent on our relationships with the TOI PCs, which are affiliated professional entities that we do not own, to provide healthcare services, and our business would be harmed if those relationships were disrupted or if our arrangements with the TOI PCs become subject to legal challenges. • If our agreements or arrangements with any physician equity holder of our TOI PCs are deemed invalid under applicable laws or are terminated as a result of changes in such laws, or if there is a change in accounting standards by the Financial Accounting Standards Board or the interpretation thereof affecting consolidation of entities, it could have a material adverse effect on our consolidation of total revenues derived from such practices. • Some jurisdictions preclude us from entering into non-compete agreements with our physicians, and other non-compete agreements and restrictive covenants applicable to certain physicians and other clinical employees may not be enforceable. • We and our TOI PCs are subject to federal, state and local laws and regulations that govern our employment practices, including minimum wage, living wage, and paid time-off requirements. Failure to comply with these laws and regulations, or changes to these laws and regulations that increase our employment related expenses, could adversely impact our operations. • We have a history of net losses, we anticipate increasing expenses in the future, and we may not be able to achieve or maintain profitability. • Each of the SPAC and the Company will incur significant transaction costs in connection with the Business Combination. • If the benefits of the Business Combination do not meet the expectations of investors or securities analysts, the market price of our securities may decline. • A market for the combined company’s securities may not develop, which would adversely affect the liquidity and price of such securities. • Financial projections with respect to the Company may not prove to be reflective of actual future results. • The Business Combination is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all. • The Company will incur significant costs and obligations as a result of being a public company. • Provisions in our charter and Delaware law may inhibit a takeover of us, which could limit the price investors might be willing to pay in the future for our common stock. • Our charter will provide, subject to limited exceptions, that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain stockholder litigation matters, which could limit stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders. • Our charter will renounce any interest or expectancy that we have in certain corporate opportunities that may be presented to our officers, directors or stockholders or their respective affiliates, other than those officers, directors, stockholders or affiliates who are our or our subsidiaries’ employees. As a result, these persons will not be required to offer certain business opportunities to us and may engage in business activities that compete with us. 44

Greetings and welcome to the DFP Healthcare Acquisitions Corp. call to discuss the proposed business combination with The Oncology Institute. At this time, all participants are on a listen-only mode. If anyone is connected via the phone and require operator assistance during the conference, please press star zero on your telephone keypad. As a reminder, this conference is being recorded. It is now my pleasure to introduce your host, Mr. Chris Wolfe, CFO of DFP Healthcare Acquisitions Corp. Thank you, sir, you may begin.

Thank you, and good morning, everyone. Thank you for joining today’s call arranged by DFP Healthcare Acquisitions Corp. I am Chris Wolfe, the CFO of DFP. Before we begin, please note that DFP Healthcare Acquisitions Corp. filed a Form 8-K containing a copy of our press release and investor presentation. This filing can be found at the website of the SEC at www.sec.gov.

I'd like to remind you that our remarks contain forward-looking statements, and we refer you to slides 2 and 3 of the presentation and to our press release for a detailed discussion of these forward-looking statements and associated risks. In addition, the presentation contains detailed reconciliations of non-GAAP financial information that will be discussed on this call. Neither DFP nor the management of our proposed merger target, The Oncology Institute, will entertain questions during this call.

With that, I'd like to introduce today's speaker, Richard Barasch, Executive Chairman of DFP and Brad Hively, CEO of The Oncology Institute and CEO of the combined company following the proposed combination with DFP.

I’ll now turn the conversation over to Richard Barasch. Richard, please go ahead.

Earlier today, we announced that we have signed a definitive agreement to combine DFP with The Oncology Institute, known as TOI. Deerfield and I are delighted to bring this disruptive and fast-growing value-based care company to the public market.

Oncology is an enormous and fast-growing segment of healthcare and for all risk-takers, oncology costs have become increasingly difficult to manage. TOI is the first scaled provider of value-based oncology and has already achieved validation and market acceptance with more than 50 community-based practice locations in four states.

Given the size and white space in the market, we think that TOI will grow significantly over the next several years, especially with the growth capital that this transaction will provide.

It’s clear that the need exists for what TOI offers and that TOI is doing something that no other company is doing in scale.

As a result of its highly scalable and replicable model, the company now serves approximately 1.3 million lives under value-based contracts with leading payors and at-risk physician groups.

The foundation for this growth is an experienced and committed management team working from a proprietary technology platform purpose built for oncology care. This platform allows TOI to collect patient information, analyze the data collected, and then dictate the appropriate plan of care.

The company will be led by its CEO Brad Hively, Chief Operating Officer Dr. Daniel Virnich,, Chief Medical Officer Dr. Yale Podnos, and Chief Financial Officer Scott Dalgleish. Collectively, these individuals and their teams have done a remarkable job in managing the expansion of TOI over the last several years. Along with growth, the team is committed to the highest levels of patient care and compliance. The fact that many of the company’s long-term clients are sponsoring TOI’s entry into new markets is further validation of the value of the model.

Brad and his team have done a terrific job building the business to this point and we are excited to see how growth will accelerate with the capital that this transaction will provide. Even in the short period of time that we have been working on the transaction, TOI has landed significant new business.

I am pleased to report that we are bringing a fully financed transaction to the market. Current shareholders of TOI are rolling approximately 70% of their holding into the new company demonstrating their belief in the future of the company. The cash portion of the deal will be funded from the $230 million DFP trust account, including $50 million invested by Deerfield that will roll over into the business combination plus approximately $275 million that we raised in the PIPE from sophisticated healthcare investors, including Deerfield, Fidelity, and Redmile. We were oversubscribed on the PIPE and we are gratified for the support of current and new investors.

The transaction values the combined company at a pro forma enterprise value of approximately $843 million and implying a multiple of 2.4x estimated 2022 revenues. Assuming no redemptions, we expect there to be 106 million shares outstanding at closing, with an initial market cap of $1.06 billion. We also expect more than $200 million of cash on the balance sheet to support our growth.

Now I'd like to turn it over to the CEO, Brad Hively, who will provide some further insight.

I want to begin by saying how excited we are to work with the DFP team. As the leading value-based oncology group in the country, we believe the team at Deerfield provides the public markets with a powerful endorsement of our achievements, our strategy, and our outlook. This transaction will, in addition to elevating our overall profile, provide the necessary capital to drive our growth, expand our reach, and support our efforts to redefine cancer care in the United States.

My journey with TOI has been more than a decade in the making. Over 10 years ago I was managing a region for a large, value-based primary care group. I asked TOI to begin caring for a large population of patients, and I immediately saw a dramatic improvement in the quality of care, cost of care, and patient satisfaction for those members. I was so impressed by what I saw from TOI that I ended up joining the company as CEO many years later.

Now I’ll provide a little context on the big picture on the opportunity ahead of us.

So, while a value-based approach to primary care is becoming more common and accepted, our healthcare system still struggles with how to manage the rising cost of specialty care. Oncology, in particular, is challenged with rising costs and poor care coordination, which is driven by several factors, including misalignment between physicians and payors; complex and variable clinical pathways; and the high cost of cancer therapies.

Here at TOI we are helping to rebuild the healthcare system in the U.S. by replacing costly, inefficient Fee For Service care with a value-based approach that aligns physicians, patients, and payors to simultaneously enhance quality and manage costs.

What we do is hard and differentiated in the oncology space. Our value-based and patient-centric care model relies on several unique features to TOI that are hard for others to replicate. Here’s a quick overview of 6 of our key differentiators:

In terms of outcomes data, our High Value Cancer Care (HVCC) model has been validated through research conducted by Stanford University which concluded that patients in the HVCC program:

Our HVCC program ensures that each patient is assigned a healthcare coach who provides constant monitoring and care plan adjustments to address any side effects of therapy, like nausea, pain, dehydration, and other symptoms related to the primary diagnosis, as well as superior access to our clinicians through appointment coordination whether in person or via telemedicine, which dramatically improves patient experience and reduces the need to turn to overcrowded emergency departments or acute care facilities to make it through treatment successfully.

With respect to acquisitions, we plan to execute against a strategy of primarily organic growth in new and existing markets, complemented by an actionable acquisition pipeline.

We are forecasting revenue of $345 million in 2022 growing thereafter at more than 50% annually for the next few years. As we ramp up, we expect gross margin to increase during this period driven by an increasing shift in payor mix towards value-based agreements, a higher number of capitated and value-based lives, geographic expansion, and the benefits of scale.

In closing, this is a very exciting day for our company. I am extremely grateful to all of our teammates who have helped us achieve this milestone, and I am excited to bring world class cancer care into more local communities around the country.

Thank you all for your time today. As we commence this process, I hope to be able to speak with many of you personally in the months ahead.

Thank you very much for your participation this morning. I invite you to review the slides that we have filed with the SEC to gain a full appreciation for why we believe this transaction is attractive to investors. We intend to file our proxy in the next couple of weeks with a view to close the transaction in the 3^rd or 4^th quarter.

Ladies and gentlemen, thank you for your participation. You may disconnect your phone line or log off the webcast at this time, and have a wonderful day.

I am incredibly excited and proud to share with you that TOI is going to be a public company. We have entered into a business combination agreement with DFP Healthcare Acquisition Corp., which is a publicly traded special purpose acquisition company (SPAC). Upon the closing of this transaction, TOI will be listed as a public company under the ticker TOI on NASDAQ. You can read the full press release here.

Looking back over the journey that brought us to this point, it is truly incredible. From the founding of our company in 2007 with one clinic in Downey, to 2018 when we welcomed a new ownership group, to 2020 when we crossed the milestone of treating our 150,000^th patient, and now to this historic day which marks our transition to becoming a public company. Since that founding, we have cared for hundreds of thousands of people and brought hope to countless patients, their families, and their friends. We’ve conducted hundreds of clinical trials, brought cutting-edge research and treatment into our local communities, and elevated the standard of care in community oncology.

This transaction will make TOI stronger, will make TOI a better place to work, and will make TOI a better place to be a patient. It will also bring TOI the capital we need to expand our team, invest in technology, broaden our service offerings, improve our patient care, and fast track our growth. We wouldn’t be here today without each of you, and I hope you are as excited as I am to embark on this next chapter of growth at TOI.

Our team will be working diligently over the next few months to clear the standard regulatory hurdles to transition to having TOI listed as a public company. As we make that transition there are certain responsibilities that all TOI employees need to be aware of during this interim status. These include:

As we enter this exciting new phase for TOI, I want to reassure you that who we are as a company and as a team will not change – we remain committed to the same mission, vision, and core values. You may have questions about what to expect in the coming weeks and months – to address those questions we are holding a company-wide town hall meeting this afternoon at 4:30pm PT. An invitation will be sent shortly and you can submit an anonymous question in advance of the town hall [here].

As exciting as this is, we must all remember that this announcement is a milestone, not an endpoint. And while celebration is certainly deserved, it’s important that we remain focused on executing our responsibilities every day. If anything, it is more important than ever to remain fiercely dedicated to our mission. This new capital we are raising comes with heightened responsibilities. We must put this money to good use, improving our patient care, improving our physician support, and enhancing the employee experience at TOI.

Lastly, I want to take a moment and recognize that we couldn’t have done this without each and every one of you. Whether you’re a medical assistant, an authorization coordinator, a nurse, an accountant, a biller, a pharmacy technician, an HR professional, an operations manager, or a customer service representative. Whether you’re in the front office interacting with patients all day long, or if you’re in ICRI managing clinical trials or in Cerritos working on eligibility. We’ve all done this together. To recognize your contributions, I will be recommending that shortly after we become a public company, all full-time employees as of today’s date who don’t currently have stock options, be considered for an equity award of 2,000 shares of TOI stock. More details on this stock will follow shortly, but this is a thank you to our heroes, our healthcare workers, who have persevered through an incredibly challenging past 18 months -- masking up, gloving up, and coming to work each and every day to make sure our patients receive the best possible care.

Thank you again for everything you do for TOI, for our patients, and for your colleagues.

A SPAC, or special purpose acquisition company, raises capital through an initial public offering (IPO) for the purpose of acquiring an existing operating company. Once that process is complete, an operating company (like TOI) can combine with the publicly traded SPAC to go public instead of going through the traditional IPO process.

The process of going public gives us the opportunity to grow and have the financial resources to expand our services and acquire the tools necessary to do so successfully. We expect this to make doing your job easier and more fulfilling, as well as allowing for more opportunities for career advancement.
