Forward-Looking Statements - Safe Harbor

This press release contains "forward-looking statements"

within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements

can be identified by words such as: "anticipate," "intend," "plan," "believe," "project,"

"estimate," "expect," "may," "should," "will" and similar references to future

periods. Examples of forward-looking statements include, among others, statements the Company may make regarding future revenues, future

earnings, other future financial results, regulatory developments, market developments, new products and growth strategies and the effects

of any of the foregoing on its future results of operations or financial condition.

Forward-looking statements are neither historical facts nor assurances

of future performance. Instead, they are based only on the Company's current beliefs, expectations and assumptions regarding the

future of its business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions.

Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances

that are difficult to predict and many of which are outside of the Company's control. The Company's actual results and financial

condition may differ materially from those indicated in the forward-looking statements. Important factors that could cause the Company's

actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others,

the following: changes in laws, regulations or trade policies applicable to its business model; loss of relationships with managed care

organizations and other non-governmental third party payers; changes in the pharmaceutical industry, including limiting or discontinuing

research, development, production and marketing of pharmaceuticals compatible with its services; changes in market conditions and receptivity

to its services and offerings; and pending and future litigation or potential liability for claims not covered by insurance. For a detailed

discussion of the risk factors that could affect its actual results, please refer to the risk factors identified in the Company's

SEC reports as filed with the SEC.

Any forward-looking statement made by the Company in this press release

is based only on information currently available to it and speaks only as of the date on which it is made. The Company undertakes no

obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as

a result of new information, future developments or otherwise.

Preliminary Unaudited Financial Data

The preliminary financial information included in this press release

is subject to completion of the Company's year-end close procedures and further financial review. The Company has provided ranges,

rather than specific amounts, because these results are preliminary and subject to change. Actual results may differ from these estimates

as a result of the completion of the Company's year-end closing procedures, review adjustments and other developments that may

arise between now and the time such financial information for the period is finalized. As a result, these estimates are preliminary,

may change and constitute forward-looking information and, as a result, are subject to risks and uncertainties. These preliminary estimates

should not be viewed as a substitute for full financial statements prepared in accordance with United States generally accepted accounting

principles ("GAAP"), and they should not be viewed as indicative of the Company's results for any future period. The

Company's independent registered public accounting firm has not audited, reviewed, compiled, or performed any procedures with respect

to these estimated financial results and, accordingly, does not express an opinion or any other form of assurance with respect to these

preliminary estimates.

Note Regarding Use of Non-GAAP Financial Measures

In addition to reporting financial information in accordance with

generally accepted accounting principles (GAAP), the Company is also reporting Adjusted net income, Adjusted EBITDA and Adjusted diluted

earnings per share ("EPS"), which are non-GAAP financial measures. These adjusted measures are not measurements of financial

performance under GAAP and should not be used in isolation or as a substitute or alternative to net income, EPS, or any other performance

measure derived in accordance with GAAP, or as a substitute or alternative to cash flow from operating activities or a measure of the

Company's liquidity. In addition, the Company's definitions of Adjusted net income, Adjusted EBITDA, and Adjusted diluted EPS may

not be comparable to similarly titled non-GAAP financial measures reported by other companies. As defined by the Company: (i) Adjusted

net income represents net income before intangible asset amortization expense, stock-based compensation expense, loss on extinguishment

of debt, and restructuring, acquisition, integration and other expenses, net of tax adjustments, (ii) Adjusted EBITDA represents net

income before net interest expense, income tax expense, depreciation and amortization, stock-based compensation expense, loss on extinguishment

of debt, and restructuring, acquisition, integration and other expenses, and (iii) Adjusted diluted EPS represents Adjusted net income

divided by weighted average common shares outstanding, diluted. As part of restructuring, acquisition, integration and other expenses,

the Company may incur significant charges such as the write down of certain long-lived assets, temporary redundant expenses, professional

fees, certain litigation expenses and reserves related to acquired businesses, potential retention and severance costs and potential

accelerated payments or termination costs for certain of its contractual obligations. Management believes that these adjusted measures

provide useful supplemental information regarding the performance of Option Care Health's business operations and facilitate comparisons

to the Company's historical operating results. The Company has not reconciled Adjusted EBITDA guidance to net income or Adjusted

diluted EPS guidance to GAAP diluted EPS as management believes creation of this reconciliation would not be practicable due to the uncertainty

regarding, and potential variability of, material reconciling items. Full reconciliations of each historical adjusted measure to the

most comparable GAAP financial measure are set forth below.
