Management

Commentary

Daniel Virnich,

CEO of TOI, commented, "The first quarter of 2026 was a strong start to the year for TOI, delivering 41% year over year revenue growth,

driven in part by strong capitated revenue growth and a record performance in our pharmacy business. We made meaningful progress on several

fronts, including in Florida, where we reached profitability, marking an important milestone that reflects the maturation of our capitated

relationships in the state, which is a proof point of our model. Our provider portal, which is designed to underscore our commitment to

high quality patient care, strengthen provider engagement, and drive continued adherence to our clinical pathways and quality metrics,

is preparing for launch this summer. Looking ahead, we are focused on building on the momentum we have coming out of this quarter, are

reaffirming our guidance for 2026 revenue and adjusted EBITDA, and feel confident in our ability to execute sustainable profitability

over the long term."

Outlook for Fiscal

Year 2026

TOI uses Adjusted EBITDA

and Free Cash flow, each a non-GAAP metric, as an additional tool to assess its operational and financial performance. See "Financial

Information: Non-GAAP Financial Measures" below. In reliance on the unreasonable efforts exception provided under Regulation S-K,

TOI is not reasonably able to provide a quantitative reconciliation for forward-looking information of Adjusted EBITDA and Free Cash flow

to net (loss) income and net cash provided by operations, respectively, the most directly comparable GAAP financial measures, without

unreasonable efforts due to uncertainties regarding capitated lives, direct costs, taxes, capital expenditures, share-based compensation,

change in fair value of liabilities, unrealized (gains) losses on investments, consulting and legal fees, transaction costs and other

non-cash items. The variability of these items could have an unpredictable, and potentially significant, impact on TOI’s future

GAAP financial results.

to $1 million, reflecting seasonal improvement as deductibles are satisfied and continued ramp of our Florida delegated lives TOI's achievement

of the anticipated results is subject to risks and uncertainties, including those disclosed in its filings with the U.S. Securities and

Exchange Commission. The outlook does not take into account the impact of any unanticipated developments in the business or changes in

the operating or economic environment, nor does it take into account the impact of TOI's acquisitions, dispositions or financings. TOI's

outlook assumes a largely stable global market, which would likely be negatively impacted if recent tariff rate increases and exchange

rate changes persist and adversely affect world trade.

Forward-Looking Statements

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 “preliminary,”

“believe,” “may,” “will,” “estimate,” “continue,” “anticipate,”

“intend,” “expect,” “should,” “would,” “plan,” “project,” “predict,”

“potential,” “guidance,” “approximately,” “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, anticipated financial results,

estimates and forecasts of revenue and other financial and performance metrics and projections of market opportunity and expectations.

These statements are based on various assumptions and on the current expectations of TOI 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 anyone 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

TOI. These forward-looking statements are subject to a number of risks and uncertainties, including the accuracy of the assumptions underlying

the 2026 full fiscal year outlook and the Q2 2026 outlook with respect to Adjusted EBITDA discussed herein, the outcome of judicial and

administrative proceedings to which TOI may become a party or investigations to which TOI may become or is subject that could interrupt

or limit TOI’s operations, result in adverse judgments, settlements or fines and create negative publicity; changes in TOI’s

patient or payors' preferences, prospects and the competitive conditions prevailing in the healthcare sector; failure to continue to meet

stock exchange listing standards; the impact of a cybersecurity incident affecting a software provider on TOI’s business; those

factors discussed in the documents of TOI filed, or to be filed, with the SEC, including the Item 1A. "Risk Factors" section

of TOI's Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 12, 2026 and any subsequent Quarterly

Reports on Form 10-Q or Current Reports on Form 8-K. 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 TOI currently is evaluating

or does not presently know or that TOI currently believes are immaterial that could also cause actual results to differ from those contained

in the forward-looking statements. In addition, forward-looking statements reflect TOI’s plans or forecasts of future events and

views as of the date of this press release. TOI anticipates that subsequent events and developments will cause TOI’s assessments

to change. TOI does not undertake any obligation to update any of these forward-looking statements. These forward-looking statements should

not be relied upon as representing TOI’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.

Financial Information; Non-GAAP Financial

Measures

Some of the financial information and data

contained in this press release, such as Adjusted EBITDA and Free Cash Flow, have not been prepared in accordance with United States generally

accepted accounting principles (“GAAP”). 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. Because of the limitations of non-GAAP financial

measures, you should consider the non-GAAP financial measures presented in this press release in conjunction with TOI’s financial

statements and the related notes thereto.

TOI believes that the use of Free Cash Flow

provides an additional tool to assess the Company's financial performance, evaluate its ability to generate cash from operations, and

plan for future investments and obligations. Free Cash Flow is useful in understanding the cash available for strategic initiatives. It

also helps in comparing TOI's financial performance with other similar companies, many of which use similar non-GAAP financial measures

to provide insights into their cash generation capabilities. However, the principal limitation of Free Cash Flow is that it does not account

for certain cash outflows or inflows that are required by GAAP to be recorded in TOI's financial statements. TOI defines Free Cash Flow

as net cash flow provided by (used in) operations plus cash paid for interest, less capital expenditures.

TOI believes that the use of Adjusted EBITDA

provides an additional tool to assess our operations and results of our performance, to plan and forecast future periods, and factors

and trends in, and in comparing our financial measures with, other similar companies, many of which present similar non-GAAP financial

measures to investors. The principal limitation of Adjusted EBITDA is that it excludes significant expenses and income that are required

by GAAP to be recorded in TOI's financial statements.

TOI defines Adjusted EBITDA as net (loss)

income plus depreciation, amortization, interest, taxes, non-cash items, share-based compensation, goodwill impairment charges, change

in fair value of liabilities, unrealized gains or losses on investments and other adjustments to add-back the following: consulting and

legal fees related to acquisitions, one-time consulting and legal fees related to certain advisory projects, software implementations

and debt or equity financings, severance expense and temporary labor and recruiting charges to build out our corporate infrastructure.

operations to Free Cash Flow and net loss to Adjusted EBITDA, the most comparable GAAP metrics, is set forth below:
