**ABOUT THIS PROSPECTUS SUPPLEMENT**

This prospectus supplement and the accompanying prospectus are part of a "shelf" registration statement on Form S-3 (File No. 333-239504) that we initially filed with the Securities and Exchange Commission (SEC) on June 26, 2020, and that was declared effective by the SEC on July 8, 2020. This document contains two parts. The first part is this prospectus supplement, which contains specific information about the terms of this offering and also supplements and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part is the accompanying prospectus, which provides more general information, some of which may not apply to this offering. If the description of the offering varies between this prospectus supplement and the accompanying prospectus, you should rely on the information in this prospectus supplement.

We, the selling stockholder and the underwriter have not authorized anyone to provide you with information or to make any representation other than the information and representations contained or incorporated by reference in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference herein and therein, along with the information contained in any permitted free writing prospectuses we have authorized for use in connection with this offering. We, the selling stockholder and the underwriter take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you.

The selling stockholder and the underwriter are offering to sell, and seeking offers to buy, shares of our common stock only in jurisdictions where offers and sales are permitted. For investors outside the United States we, the selling stockholder and the underwriter have not done anything that would permit this offering or possession or distribution of this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering must inform themselves about, and observe any restrictions relating to, the offering of the shares of common stock and the distribution of this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering outside the United States.

The information contained in this prospectus supplement and the accompanying prospectus is accurate only as of the date of this prospectus supplement or the date of the accompanying prospectus, as applicable, and the information in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus is accurate only as of the date of those respective documents, regardless of the time of delivery of this prospectus supplement and the accompanying prospectus or of any sale of our common stock. Our business, financial condition, results of operations and prospects may have changed since those dates. It is important for you to read and consider all information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus in making your investment decision. You should read this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering, as well as the documents incorporated by reference herein and therein and the additional information described under "Where You Can Find More Information" and "Incorporation of Certain Information by Reference" in this prospectus supplement and in the accompanying prospectus, before investing in our common stock.

**FORWARD-LOOKING STATEMENTS**

This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein may contain and refer to certain statements that are not historical facts that contain "forward-looking statements." Some of these statements can be identified by terms and phrases such as "anticipate," "believe," "intend," "estimate," "expect," "continue," "could," "may," "plan," "project," "predict" and similar expressions and include references to assumptions that we believe are reasonable and relate to our future prospects, developments and business strategies. Such statements are subject to various risks and uncertainties that could cause actual results to differ materially from those anticipated due to a number of facts, including but not limited to those described from time to time in our reports filed or furnished with the SEC, and in particular those factors set forth in the section entitled "Risk Factors" in our annual and quarterly reports filed with the SEC.

While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. All forward-looking statements are expressly qualified in their entirety by these cautionary statements.

All forward-looking statements speak only as of the date on which they are made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to update any forward-looking statement, whether as a result of new information, future developments or otherwise. If we do update one or more forward-looking statements, there should be no inference that we will make additional updates with respect to those or other forward-looking statements.

**PROSPECTUS SUPPLEMENT SUMMARY**

*This summary highlights selected information contained in greater detail elsewhere in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein and does not contain all of the information that you should consider in making your investment decision. Before investing in our common stock, you should carefully read the entire prospectus supplement, accompanying prospectus, any free writing prospectus that we have authorized for use in connection with this offering and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, especially the risks of investing in our common stock discussed under the heading "Risk Factors," and our financial statements and related notes incorporated by reference in this prospectus supplement and the accompanying prospectus.*

**Overview**

Option Care Health and its wholly-owned subsidiaries provide infusion therapy and other ancillary health care services through our national network of 163 locations around the United States. We contract with managed care organizations, third-party payers, hospitals, physicians, and other referral sources to provide pharmaceuticals and complex compounded solutions to patients for intravenous delivery in the patients' homes or other nonhospital settings. Our services are provided in coordination with, and under the direction of, the patient's physician. Our multidisciplinary team of clinicians, including pharmacists, nurses, dietitians and respiratory therapists, work with the physician to develop a plan of care suited to each patient's specific needs. We provide home infusion services consisting of anti-infectives, nutrition support, chronic inflammatory disorders and neurological disorders, immunoglobulin therapy, and other therapies for chronic and acute conditions.

Our operating model enables us to provide favorable outcomes to our stakeholders as follows:

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Patients*** . We improve our patients' quality of life by allowing them to receive infusion therapy at home or
at one of our ambulatory infusion suites. In addition, we help manage patients' conditions through counseling and education regarding
their treatment and by providing ongoing monitoring to encourage patient compliance with the prescribed therapy. We also provide services
to help patients receive reimbursement benefits.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Payers*** . We provide payers with a comprehensive approach to meeting their pharmacy service needs and providing a
cost-effective solution. Our provision of infusion pharmacy services in the patient's home or at one of our local ambulatory infusion
suites offers a lower cost alternative to providing these therapies in a hospital setting. We also provide payers with utilization and
outcome data to evaluate therapy effectiveness.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Providers*** . We provide providers with timely patient clinical support by providing care management related to their
patients' pharmacy needs and improving compliance with therapy protocols. We eliminate the need for providers to carry inventories
of high-cost prescriptions by distributing the medications directly to patients' homes.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Pharmaceutical Manufacturers*** . We collaborate with pharmaceutical manufacturers to provide a broad distribution
channel for their existing pharmaceuticals and their new product launches. We implement patient monitoring programs that encourage compliance
with the prescribed therapy. We also provide valuable clinical information in the form of outcomes and compliance data to manufacturers
to aid in their evaluation of the efficacy of their products.

&nbsp;&nbsp;&nbsp;&nbsp;·  ***Health Systems*** . We partner with health systems across the country to provide an effective post-acute care network
to manage patients across the continuum of care.

On April 7, 2015, HC Group Holdings II, Inc. ("HC II") and its sole shareholder, HC Group Holdings I, LLC ("HC I"), collectively acquired Walgreens Infusion Services, Inc. and its subsidiaries from Walgreen Co. ("Walgreens"), and the business was rebranded as Option Care, Inc. ("Option Care").

On March 14, 2019, HC I and HC II entered into a definitive agreement (the "Merger Agreement") to merge with and into a wholly-owned subsidiary of BioScrip, Inc. ("BioScrip") (the "Merger"), a national provider of infusion and home care management solutions, which was completed on August 6, 2019. Following the close of the Merger, BioScrip was rebranded as Option Care Health, Inc.

**Concurrent Share Repurchase**

We have entered into an agreement to concurrently repurchase directly from the selling stockholder 2,475,166 shares of our common stock. The price per share to be paid by us will equal the price at which the underwriter will purchase the shares from the selling stockholder in this offering, net of underwriting discounts and commissions. We refer to this transaction as the "concurrent share repurchase." The concurrent share repurchase will be made under the Company's share repurchase program, which was approved by the Company's Board of Directors (the "Board") on February 20, 2023 and had $250 million of availability remaining as of February 23, 2023. Any shares that we repurchase in the concurrent share repurchase will be held in treasury and will reduce the availability remaining under our share repurchase program. The closing of the concurrent share repurchase will be conditioned upon the closing of this offering and therefore there can be no assurance that the concurrent share repurchase will be completed. This offering is not conditioned upon the completion of the concurrent share repurchase.

The concurrent share repurchase was approved by the Audit Committee of the Board. We intend to fund the concurrent share repurchase with cash on hand.

The description of, and the other information in this prospectus supplement regarding, the concurrent share repurchase is included in this prospectus supplement for informational purposes only. Nothing in this prospectus supplement should be construed as an offer to sell, or the solicitation of an offer to buy, any of our shares of common stock subject to the concurrent share repurchase.

Our principal executive offices are located at 3000 Lakeside Drive, Suite 300N, Bannockburn, Illinois 60015, and our telephone number at that address is (312) 940-2443.

**RISK FACTORS**

Investing in our securities involves a high degree of risk. You should carefully consider the information contained in this prospectus supplement and the accompanying prospectus, together with all of the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. You should also consider the risks and uncertainties described under the caption "Risk Factors" in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are incorporated by reference in this prospectus supplement and the accompanying prospectus. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The market or trading price of our securities could decline due to any of these risks, and you may lose all or part of your investment. Please note that additional risks not presently foreseen by us or that we currently deem immaterial may also impair our business and operations.

**Risks Related to This Offering**

***As of the date of this prospectus supplement, Walgreens Boots Alliance, Inc. ("Walgreens") is our largest stockholder and has the ability to exercise influence over decisions requiring our stockholders' approval.***

As of the date of this prospectus supplement, before giving effect to this offering, Walgreens controls approximately 14.4% of our common stock through its control of HC I. As a result, Walgreens has the ability to exercise influence over decisions requiring approval of our stockholders including the election of directors, amendments to our certificate of incorporation and approval of significant corporate transactions, such as a merger or change in control of the Company.

***Provisions of our corporate governance documents could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our current management, even if beneficial to our stockholders.***

In addition to Walgreens' beneficial ownership of approximately 14.4% of our common stock, our third amended and restated certificate of incorporation contains provisions that could make it more difficult for a third party to acquire us, even if doing so might be beneficial to our stockholders. Among other things:

· these provisions allow us to authorize the issuance of undesignated preferred stock, the terms of which may be established and the
shares of which may be issued without stockholder approval, and which may include supermajority voting, special approval, dividend, or
other rights or preferences superior to the rights of stockholders;

· these provisions provide that directors may be removed with or without cause only by the affirmative vote of holders of at least 66<sup>2</sup>∕3%
of the voting power of all the then-outstanding shares of our stock entitled to vote thereon, voting together as a single class;

· these provisions prohibit stockholder action by written consent; and

· these provisions provide that any amendment, alteration, rescission or repeal of our bylaws or certificate of incorporation by our
stockholders will require the affirmative vote of the holders of at least 66<sup>2</sup>∕3% of the voting power of all the then-outstanding
shares of our stock entitled to vote thereon, voting together as a single class.

These and other provisions in our certificate of incorporation, bylaws and Delaware law could make it more difficult for shareholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by our then-current board of directors, including delay or impede a merger, tender offer or proxy contest involving the Company. The existence of these provisions could negatively affect the price of our common stock and limit opportunities to realize value in a corporate transaction.

Moreover, Section 203 of the Delaware General Corporation Law ("DGCL") may discourage, delay, or prevent a change of control of the Company. Section 203 of the DGCL imposes certain restrictions on mergers, business combinations, and other transactions between us and holders of 15% or more of our common stock.

***Our third amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us.***

***We may issue shares of preferred stock in the future, which could make it difficult for another company to acquire us or could otherwise adversely affect holders of our common stock, which could depress the price of our common stock.***

Our third amended and restated certificate of incorporation authorizes us to issue one or more series of preferred stock. Our board of directors has the authority to determine the preferences, limitations and relative rights of the shares of preferred stock and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by our stockholders. Our preferred stock could be issued with voting, liquidation, dividend and other rights superior to the rights of our common stock. The potential issuance of preferred stock may delay or prevent a change in control, discouraging bids for our common stock at a premium to the market price, and materially and adversely affecting the market price and the voting and other rights of the holders of our common stock.

**USE OF PROCEEDS**

We will not receive any of the proceeds from the shares of common stock sold by the selling stockholder.

**SELLING STOCKHOLDER**

The following table and accompanying footnotes sets forth, as of the date of this prospectus supplement, information with respect to the beneficial ownership of our common stock by the selling stockholder, as adjusted, with respect to shares beneficially owned after the offering, to reflect the sale of shares of common stock by the selling stockholder in this offering and the concurrent share repurchase.

The percentage of common stock owned by the selling stockholder is based on 181,957,711 shares of common stock outstanding as of February 20, 2023 and, where indicated, gives effect to the repurchase by us of 2,475,166, shares of our common stock in the concurrent share repurchase. Information with respect to beneficial ownership is based on information obtained from such selling stockholder and publicly available information.

**MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS**

The following is a general discussion of the material U.S. federal income tax considerations applicable to non-U.S. holders (as defined herein) with respect to their ownership and disposition of shares of our common stock acquired pursuant to this offering. All prospective non-U.S. holders of our common stock should consult their own tax advisors with respect to the U.S. federal, state, local and non-U.S. tax consequences of the purchase, ownership and disposition of our common stock. In general, a non-U.S. holder means a beneficial owner of our common stock (other than a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not or is not treated as, for U.S. federal income tax purposes:

· An individual who is a citizen or resident of the United States;

· A corporation created or organized under the laws of the United States or of any state thereof or the District of Columbia;

· An estate, the income of which is includable in gross income for U.S. federal income tax purposes regardless of its source; or

· A trust if (1) a U.S. court can exercise primary supervision over the trust's administration and one or more U.S. persons
(within the meaning of Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended (the "Code")) have the authority
to control all of the trust's substantial decisions or (2) the trust has a valid election in effect under applicable U.S. Treasury
Regulations to be treated as a U.S. person.

This discussion is based on current provisions of the Code, existing U.S. Treasury Regulations promulgated thereunder, published administrative pronouncements and rulings of the U.S. Internal Revenue Service (the "IRS") and judicial decisions, all as in effect as of the date of this prospectus supplement. These authorities are subject to change and to differing interpretation, possibly with retroactive effect. Any change or differing interpretation could alter the tax consequences to non-U.S. holders described in this prospectus supplement and the accompanying prospectus.

We assume in this discussion that a non-U.S. holder holds shares of our common stock as a capital asset within the meaning of Section 1221 of the Code (generally, for investment). This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder's individual circumstances, nor does it address any estate or gift tax consequences, or any aspects of U.S. state, local or non-U.S. taxation. This discussion also does not consider any specific facts or circumstances that may apply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, including, but not limited to, holders that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below), corporations that accumulate earnings to avoid U.S. federal income tax, tax-exempt organizations, banks, financial institutions, insurance companies, regulated investment companies, real estate investment trusts, brokers, dealers or traders in securities, commodities or currencies, tax-qualified retirement plans, "qualified foreign pension funds" as defined in Section 897(1)(2) of the Code and entities in which all of the interests of which are held by qualified foreign pension funds or U.S. expatriates and former long-term residents of the United States, holders subject to the Medicare contribution tax on net investment income or the alternative minimum tax, holders that are subject to the special tax accounting rules of Section 451(b) of the Code, holders who hold or receive our common stock pursuant to the exercise of employee stock options or otherwise as compensation, holders holding our common stock as part of a hedge, straddle or other risk reduction strategy, conversion transaction or other integrated investment, holders deemed to sell our common stock under the constructive sale provisions of the Code, controlled foreign corporations, passive foreign investment companies and certain former U.S. citizens or long-term residents.

In addition, this discussion does not address the tax treatment of partnerships (or entities or arrangements that are treated as partnerships for U.S. federal income tax purposes) or persons that hold our common stock through such partnerships. If a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes, holds shares of our common stock, the U.S. federal income tax treatment of a partner in such partnership will generally depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Such partners and partnerships should consult their own tax advisors regarding the tax consequences of the purchase, ownership and disposition of our common stock.

There can be no assurance that a court or the IRS will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling with respect to the U.S. federal income tax consequences to a non-U.S. holder of the purchase, ownership or disposition of our common stock.

**Distributions on our Common Stock**

If we make distributions of cash or property on our common stock, such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder's investment, up to such holder's adjusted tax basis in the common stock. Any remaining excess will be treated as capital gain from the sale or exchange of such common stock, subject to the tax treatment described below in "Gain on Sale, Exchange or other Disposition of our Common Stock." Any such distribution will also be subject to the discussion below regarding effectively connected income, backup withholding and FATCA withholding.

Dividends paid to a non-U.S. holder will generally be subject to withholding of U.S. federal income tax at a 30% rate of the gross amount of dividends or such lower rate as may be specified by an applicable income tax treaty between the U.S. and such holder's country of residence.

Dividends that are treated as effectively connected with a trade or business conducted by a non-U.S. holder within the U.S. and, if an applicable income tax treaty so provides, that are attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder within the U.S., are generally exempt from the 30% withholding tax if the non-U.S. holder satisfies applicable certification and disclosure requirements. However, such U.S. effectively connected income, net of specified deductions and credits, is taxed at the same regular U.S. federal income tax rates applicable to U.S. persons (as defined in the Code). Any U.S. effectively connected earnings and profits of a non-U.S. holder that is a corporation may also, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the U.S. and such holder's country of residence.

To claim a reduction or exemption from withholding, a non-U.S. holder of our common stock generally will be required to provide (a) a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form), as applicable, and satisfy applicable certification and other requirements to claim the benefit of an applicable income tax treaty between the U.S. and such holder's country of residence, or (b) a properly executed IRS Form W-8ECI stating that dividends are not subject to withholding because they are effectively connected with such non-U.S. holder's conduct of a trade or business within the U.S.. Non-U.S. holders are urged to consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty.

A non-U.S. holder that is eligible for a reduced rate of U.S. withholding tax under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

**Gain on Sale, Exchange or other Disposition of our Common Stock**

Subject to the discussion below regarding backup withholding and FATCA withholding, in general, a non-U.S. holder will not be subject to any U.S. federal income tax on any gain realized upon such holder's sale, exchange or other disposition of shares of our common stock unless:

&nbsp;&nbsp;&nbsp;&nbsp;· The gain is effectively connected with a U.S. trade or business of the non-U.S. holder and, if an applicable income tax treaty so
provides, is attributable to a permanent establishment or a fixed base maintained in the U.S. by such non-U.S. holder, in which case the
non-U.S. holder generally will be taxed at the regular U.S. federal income tax rates applicable to U.S. persons (as defined in the Code)
and be required to file a U.S. federal income tax return. If the non-U.S. holder is treated as a foreign corporation for U.S. federal
income tax purposes, the branch profits tax described above in "Distributions on our Common Stock" also may apply;

&nbsp;&nbsp;&nbsp;&nbsp;· The non-U.S. holder is an individual who is treated as present in the U.S. for 183 days or more in the taxable year of the disposition
and certain other conditions are met, in which case the non-U.S. holder will be subject to a flat 30% tax (or such lower rate as may be
specified by an applicable income tax treaty) on the gain derived from the disposition, which may be offset by U.S. source capital losses
of the non-U.S. holder, if any (even though the individual is not considered a resident of the U.S.); or

&nbsp;&nbsp;&nbsp;&nbsp;· Our common stock constitutes a U.S. real property interest because we are, or have been, at any time during the five-year period ending
on the date of such disposition (or the non-U.S. holder's holding period of our common stock, if shorter) a "United States
real property holding corporation" for U.S. federal income tax purposes. Generally, a corporation is a U.S. real property holding
corporation only if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value
of its worldwide real property interests plus its other assets used or held for use in a trade or business. Although there can be no assurance,
we do not believe that we are, or have been, a U.S. real property holding corporation, or that we are likely to become one in the future.
Even if we are or become a U.S. real property holding corporation, provided that our common stock is regularly traded, as defined by applicable
Treasury Regulations, on an established securities market during the calendar year in which the disposition occurs, only a non-U.S. holder
that holds more than 5% of our outstanding common stock, directly or indirectly, actually or constructively, during the shorter of the
5-year period ending on the date of the disposition or the period that the non-U.S. holder held our common stock will be subject to U.S.
federal income tax on the disposition of our common stock. In such case, such non-U.S. holder generally will be taxed on its net gain
derived from the disposition at the regular U.S. federal income tax rates applicable to U.S. persons (as defined in the Code). No assurance
can be provided that our common stock will continue to be regularly traded on an established securities market for purposes of the rules described
above.

**Information Reporting and Backup Withholding**

We must report annually to the IRS and to each non-U.S. holder the gross amount of the dividends on our common stock paid to such holder and the tax withheld, if any, with respect to such dividends. A non-U.S. holder will have to comply with specific certification procedures to establish that the holder is not a U.S. person (as defined in the Code) in order to avoid backup withholding at the applicable rate (currently 24%) with respect to dividends on our common stock. A non-U.S. holder generally will not be subject to U.S. backup withholding with respect to payments of dividends on our common stock if such holder establishes an exemption by certifying his, her or its non-U.S. status by providing a valid IRS Form W-8BEN or W-8BEN-E (or other applicable or successor form); provided we do not have actual knowledge or reason to know that such non-U.S. holder is a U.S. person (as defined in the Code).

Information reporting and backup withholding will generally apply to the proceeds of a disposition of our common stock by a non-U.S. holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the holder establishes an exemption by certifying his, her or its status as a non-U.S. holder and satisfies certain other requirements. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a non-U.S. holder where the transaction is effected outside the U.S. through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker. Non-U.S. holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available to the tax authorities of the country in which the non-U.S. holder resides or is incorporated under the provisions of a specific treaty or agreement.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder may be allowed as a credit against the non-U.S. holder's U.S. federal income tax liability, if any, and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

**FATCA Withholding**

Sections 1471 through 1474 of the Code, and the U.S. Treasury Regulations and other administrative guidance issued thereunder, commonly referred to as "FATCA," generally impose a U.S. federal withholding tax of 30% on dividends on, and, subject to the proposed Treasury regulations discussed below, the gross proceeds from a sale or other disposition of, stock in a U.S. corporation paid to (i) a "foreign financial institution" (as specifically defined for this purpose), unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities certain information regarding certain U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise qualifies for an exemption from these rules, or (ii) a "non-financial foreign entity" (as defined in the Code), unless such entity provides the withholding agent with either a certification that it does not have any direct or indirect "substantial United States owners" (as defined in the Code) or provides the applicable withholding agent with a certification identifying, and information regarding, such substantial United States owners, or otherwise qualifies for an exemption from these rules. An intergovernmental agreement between the U.S. and the non-U.S. holder's country of residence may modify the requirements described in this paragraph.

U.S. Treasury Regulations proposed in December 2018 eliminate possible FATCA withholding on the gross proceeds from a sale or other disposition of our common stock, and may be relied upon by taxpayers until final regulations are issued.

We will not pay additional amounts or "gross up" payments to holders as a result of any withholding or deduction for taxes imposed under FATCA. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. Investors are encouraged to consult with their tax advisors regarding the implications of FATCA to their particular circumstances.

EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK.

**UNDERWRITING**

Subject to the terms and conditions set forth in an underwriting agreement among us, the selling stockholder and Goldman Sachs & Co. LLC (the "underwriter"), the selling stockholder has agreed to sell to the underwriter, and the underwriter has agreed to purchase from the selling stockholder, 13,000,000 shares of common stock, which does not include 2,475,166 shares of common stock that we intend to repurchase directly from the selling stockholder.

We and the selling stockholder have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriter may be required to make in respect of those liabilities.

The underwriter is offering the shares of common stock, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriter of officer's certificates and legal opinions. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

**Commissions and Discounts**

The underwriter has advised us and the selling stockholder that the underwriter proposes initially to offer the shares of common stock to the public at the public offering price set forth on the cover page of this prospectus and to dealers at that price less a concession not in excess of $0.2245 per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table shows the public offering price, underwriting discount and proceeds before expenses to the selling stockholder.

---

| | | |
|:---|:---|:---|
|  | **Per Share** | **Total** |
| Public offering price | $30.750 | $399750000 |
| Underwriting discount and commissions to be paid by selling stockholder | $0.449 | $5837000 |
| Proceeds, before expenses, to the selling stockholder | $30.301 | $393913000 |

---

The expenses of the offering, not including the underwriting discount, are estimated at $400,000 and are payable by us. We have agreed to reimburse the underwriter for certain of its expenses in an amount up to $20,000.

**No Sales of Similar Securities**

We and the selling stockholder, our executive officers and certain of our directors affiliated with the selling stockholder have agreed not to sell or transfer any common stock or securities convertible into, exchangeable for, exercisable for, or repayable with common stock, for 30 days after the date of this prospectus without first obtaining the written consent of the underwriter. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:

&nbsp;&nbsp;&nbsp;&nbsp;· offer, pledge, sell or contract to sell any common stock,

&nbsp;&nbsp;&nbsp;&nbsp;· sell any option or contract to purchase any common stock,

&nbsp;&nbsp;&nbsp;&nbsp;· purchase any option or contract to sell any common stock,

&nbsp;&nbsp;&nbsp;&nbsp;· grant any option, right or warrant for the sale of any common stock,

&nbsp;&nbsp;&nbsp;&nbsp;· lend or otherwise dispose of or transfer any common stock,

&nbsp;&nbsp;&nbsp;&nbsp;· request or demand that we file a registration statement related to the common stock, or

&nbsp;&nbsp;&nbsp;&nbsp;· enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of any common stock
whether any such swap or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.

This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

**Nasdaq Global Market Select Listing**

The shares are listed on the Nasdaq under the symbol "OPCH."

**Price Stabilization, Short Positions**

Until the distribution of the shares is completed, SEC rules may limit the underwriter and selling group members from bidding for and purchasing our common stock. However, the underwriter may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

Similar to other purchase transactions, the underwriter's purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriter may conduct these transactions on the Nasdaq, in the over-the-counter market or otherwise.

Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

**Passive Market Making**

In connection with this offering, the underwriter and selling group members may engage in passive market making transactions in the common stock on the Nasdaq in accordance with Rule 103 of Regulation M under the Exchange Act during a period before the commencement of offers or sales of common stock and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker's bid, that bid must then be lowered when specified purchase limits are exceeded. Passive market making may cause the price of our common stock to be higher than the price that otherwise would exist in the open market in the absence of those transactions. The underwriter and dealers are not required to engage in passive market making and may end passive market making activities at any time.

**Electronic Distribution**

In connection with the offering, the underwriter or certain of the securities dealers may distribute prospectuses by electronic means, such as e-mail.

**Other Relationships**

The underwriter and its affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. The underwriter and its affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses.

In addition, in the ordinary course of their business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

**Neither we nor the selling stockholders have authorized any dealer, salesperson or other person to give any information or to make any representation other than those contained or incorporated by reference in this prospectus and the applicable supplement to this prospectus or any associated free writing prospectus. In this prospectus, any reference to an applicable prospectus supplement may refer to a free writing prospectus, unless the context otherwise requires. You must not rely upon any information or representation not contained or incorporated by reference in this prospectus or the applicable prospectus supplement. This prospectus and the applicable prospectus supplement do not constitute an offer to sell or the solicitation of an offer to buy any securities other than the registered securities to which they relate, nor do this prospectus and the applicable prospectus supplement constitute an offer to sell or the solicitation of an offer to buy securities in any jurisdiction to any person to whom it is unlawful to make such offer or solicitation in such jurisdiction.**

**ABOUT THIS PROSPECTUS**

This prospectus is part of a registration statement on Form S-3 that we filed with the SEC using a "shelf" registration process. Under this shelf process, we may, from time to time, and the selling stockholders may, from time to time, offer and sell our securities in one or more offerings.

This prospectus provides you with a general description of the securities that we and the selling stockholders may offer. Each time we or the selling stockholders sell our securities, we will, to the extent required by law, provide a prospectus supplement that contains specific information about the terms of that offering. This prospectus may not be used to consummate sales of our securities unless it is accompanied by a prospectus supplement.

You should assume that the information appearing in this prospectus and any applicable prospectus supplement is accurate as of the date on its respective cover, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates.

If the description of the offering varies between any prospectus supplement and this prospectus, you should rely on the information in the applicable prospectus supplement. Any statement made in this prospectus or in a document incorporated by reference in this prospectus will be modified or superseded for purposes of this prospectus to the extent that a statement contained in this prospectus or in any other subsequently filed document that is also incorporated by reference in this prospectus modifies or supersedes that statement. Any statement so modified or superseded will not, except as so modified or superseded, constitute a part of this prospectus. Before making an investment in our securities, you should carefully read this prospectus, any applicable prospectus supplement and any applicable free writing prospectus, together with the information incorporated and deemed to be incorporated by reference herein as described under "Incorporation of Certain Information by Reference" and the additional information described under the heading "Where You Can Find More Information."

Except where the context otherwise requires or where otherwise indicated, references in this prospectus to "Option Care Health," the "Company," "we," "us," and "our" refer to Option Care Health, Inc., a Delaware corporation.

**FORWARD-LOOKING STATEMENTS**

This prospectus, any applicable prospectus supplement and the documents incorporated by reference may contain and refer to certain statements that are not historical facts that contain "forward-looking statements." Some of these statements can be identified by terms and phrases such as "anticipate," "believe," "intend," "estimate," "expect," "continue," "could," "may," "plan," "project," "predict" and similar expressions and include references to assumptions that the Company believes are reasonable and relate to its future prospects, developments and business strategies. Such statements are subject to various risks and uncertainties that could cause actual results to differ materially from those anticipated due to a number of facts, including but not limited to those described from time to time in our reports filed or furnished with the SEC, and in particular those factors set forth in the section entitled "Risk Factors" in our annual and quarterly reports filed with the SEC.

While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. All forward-looking statements are expressly qualified in their entirety by these cautionary statements.

All forward-looking statements speak only as of the date on which they are made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to update any forward-looking statement, whether as a result of new information, future developments or otherwise. If we do update one or more forward-looking statements, there should be no inference that we will make additional updates with respect to those or other forward-looking statements.

**THE COMPANY**

Option Care Health, and its wholly-owned subsidiaries, provides infusion therapy and other ancillary health care services through a national network of 155 locations around the United States. The Company contracts with managed care organizations, third-party payers, hospitals, physicians, and other referral sources to provide pharmaceuticals and complex compounded solutions to patients for intravenous delivery in the patients' homes or other nonhospital settings. Our services are provided in coordination with, and under the direction of, the patient's physician. Our multidisciplinary team of clinicians, including pharmacists, nurses, dietitians and respiratory therapists, work with the physician to develop a plan of care suited to each patient's specific needs. We provide home infusion services consisting of anti-infectives, nutrition support, bleeding disorder therapies, immunoglobulin therapy, and other therapies for chronic and acute conditions.

HC Group Holdings II, Inc. ("HC II") was incorporated under the laws of the State of Delaware on January 7, 2015, with its sole shareholder being HC Group Holdings I, LLC. ("HC I"). On April 7, 2015, HC I and HC II collectively acquired Walgreens Infusion Services, Inc. and its subsidiaries from Walgreen Co., and the business was rebranded as Option Care, Inc. ("Option Care").

On March 14, 2019, HC I and HC II entered into a definitive agreement to merge with and into a wholly-owned subsidiary of BioScrip, Inc. ("BioScrip") (the "Merger"), a national provider of infusion and home care management solutions, which was completed on August 6, 2019. The Merger was accounted for as a reverse merger under the acquisition method of accounting for business combinations with Option Care being considered the accounting acquirer and BioScrip being considered the legal acquirer. Following the close of the transaction, BioScrip was rebranded as Option Care Health, Inc.

**Corporate Information**

Our principal executive offices are located at 3000 Lakeside Drive, Suite 300N, Bannockburn, Illinois 60015, and our telephone number at that address is (312) 940-2443. Our website address is *www.optioncarehealth.com*. The information on our website is not part of this prospectus and you should not rely on that information when making a decision whether to invest in our securities.

**RISK FACTORS**

Investing in our securities involves a high degree of risk. You should carefully consider the risks and uncertainties described under the caption "Risk Factors" in our Annual Report and Quarterly Reports, which are incorporated by reference herein. You should also consider any "Risk Factors" contained in any applicable prospectus supplement, and in any document that we file with the SEC after the date of this prospectus that is incorporated by reference herein. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The market or trading price of our securities could decline due to any of these risks, and you may lose all or part of your investment. Please note that additional risks not presently foreseen by us or that we currently deem immaterial may also impair our business and operations.

**USE OF PROCEEDS**

Unless otherwise indicated in any applicable prospectus supplement, we intend to use the net proceeds from the sale of any securities offered by us under this prospectus and any related prospectus supplement for our operations and for general corporate purposes. These purposes may include financing of acquisitions and capital expenditures, additions to working capital and repayment or redemption of indebtedness, among other items. Additional information on the use of net proceeds from the sale of securities that we may offer from time to time by this prospectus will be set forth in the applicable prospectus supplement relating to a particular offering.

We will not receive any proceeds from the sale of shares of our common stock by any selling stockholder. All of the shares of common stock offered by the selling stockholders pursuant to this prospectus will be sold by the selling stockholders for their own account.

**SELLING STOCKHOLDERS**

The selling stockholders may from time to time offer and sell any or all of the shares of common stock set forth below pursuant to this prospectus and any prospectus supplement. We are registering the resale of these shares pursuant to registration rights that we have granted to such selling stockholders.

When we refer to the "selling stockholders" in this prospectus, we mean the stockholders listed in the table below, and the donees, pledgees, transferees, assignees or other successors-in-interest and others who later come to hold any of the selling stockholders' interest in shares of our common stock other than through a public sale, or any stockholders as may be named in one or more prospectus supplements, which will set forth the name of each of the stockholders and the number of securities beneficially owned by such stockholders that are covered by such prospectus supplement.

The following table sets forth, as of the date of this prospectus, the name of the selling stockholders and the aggregate amount of shares of common stock that the selling stockholders may offer pursuant to this prospectus. The percentage of common stock owned by the selling stockholders, both prior to and following the offering of any shares of common stock pursuant to this prospectus, is based on 176,714,792 shares of common stock outstanding as of June 24, 2020. Information with respect to beneficial ownership is based on information obtained from such selling stockholder and publicly available information. Information with respect to shares beneficially owned after the offering assumes the sale of all the shares offered and no other purchases or sales of common stock.

**DESCRIPTION OF CAPITAL STOCK**

The following is a description of our capital stock. The following is a summary, does not purport to be complete and is subject to our Third Amended and Restated Certificate of Incorporation (our "charter"), our Second Amended and Restated Bylaws (our "bylaws"), and provisions of applicable law. The following description does not purport to be complete and is subject to, and qualified in its entirety by, the full text of our charter and our bylaws, which have been filed as exhibits to the registration statement of which this prospectus forms a part.

**General**

Our authorized capital stock consists of 250,000,000 shares of common stock, par value $0.0001 per share, and 12,500,000 shares of preferred stock, par value $0.0001 per share.

**Common Stock**

*Voting Rights*

Each share of common stock entitles the holder thereof of one vote for each share held by such holder on all matters voted on by our stockholders, provided, however, that, except as otherwise required by law, holders of common stock are not entitled to vote on any amendment to our charter (including any certificate of designation relating to any series of preferred stock) that relates solely to the terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to our charter (including any certificate of designation relating to any series of preferred stock) or pursuant to the General Corporation Law of the State of Delaware (the "DGCL").

*Ranking*

Except as otherwise required by law or expressly provided in the our charter, each share of common stock has the same powers, rights and privileges and rank equally, share ratably and be identical in all respects as to all matters.

*Dividends*

Subject to the rights of the holders of preferred stock and to the other provisions of applicable law and our charter, holders of common stock will be entitled to receive equally, on a per share basis, such dividends and other distributions in cash, securities or other property if, as and when declared thereon by our Board of Directors (the "Board") from time to time out of our assets or funds legally available therefor.

*Liquidation*

Subject to the rights of holders of preferred stock, in the event of any liquidation, dissolution or winding up of our affairs, whether voluntary or involuntary, after payment or provision for payment of our debts and any other payments required by law and amounts payable upon shares of preferred stock ranking senior to the shares of common stock upon such dissolution, liquidation or winding up, if any, our remaining net assets will be distributed to the holders of shares of common stock and the holders of shares of any other class or series ranking equally with the shares of common stock upon such dissolution, liquidation or winding up, equally on a per share basis.

*No Preemptive or Similar Rights*

Our common stock is not entitled to preemptive rights, conversion or other rights to subscribe for additional securities and there are no redemption or sinking fund provisions applicable to our common stock.

**Preferred Stock**

The Board is authorized, subject to limitations prescribed by law, to provide, by resolution or resolutions for the issuance of shares of preferred stock in one or more series, and with respect to each series, to establish the number of shares to be included in each such series, and to fix the voting powers (if any), designations, powers, preferences, and relative, participating, optional or other special rights, if any, of the shares of each such series, and any qualifications, limitations or restrictions thereof. The powers (including voting powers), preferences, and relative, participating, optional and other special rights of each series of preferred stock and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding. Subject to the rights of the holders of any series of preferred stock, the number of authorized shares of preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the approval of the Board and by the affirmative vote of the holders of a majority in voting power of the outstanding shares of our capital stock entitled to vote generally in an election of directors, without the separate vote of the holders of the preferred stock as a class, irrespective of the provisions of Section 242(b)(2) of the DGCL.

**Certain Effects of Authorized but Unissued Stock**

We may issue additional shares of common stock or preferred stock without stockholder approval, subject to applicable rules of the The Nasdaq Stock Market LLC and Delaware law, for a variety of corporate purposes, including future public or private offerings to raise capital, corporate acquisitions, and employee benefit plans and equity grants. The existence of unissued and unreserved common stock and preferred stock may enable us to issue shares to persons who are friendly to current management, which could discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger, or otherwise.

**Anti-Takeover Effects of Provisions of our Charter and Bylaws**

The following is a brief description of the provisions in our charter and bylaws that could have an effect of delaying, deferring, or preventing a change in control of the Company.

*Director Nominations, Vacancies and Removal*

Subject to the rights of the holders of any series of preferred stock then outstanding and except as otherwise set forth in that certain Director Nomination Agreement between the Company and HC I, as described below, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the Board resulting from death, resignation, disqualification, removal from office or any other cause may be filled only by resolution of a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and may not be filled in any other manner. We and HC I entered into the Director Nomination Agreement on August 6, 2019 (the "Director Nomination Agreement").

The Director Nomination Agreement automatically terminates on the date on which HC I and its affiliates cease to beneficially own at least 10% of the total voting power of the then outstanding common stock.

Subject to the rights of the holders of any series of preferred stock then outstanding and notwithstanding any other provision of our charter, on and after the first date (the "Trigger Date") on which HC I and its Affiliated Companies (as defined below) cease to beneficially own (directly or indirectly) 50% or more of the voting power of the then outstanding shares of our capital stock then entitled to vote generally in the election of directors ("Voting Stock"), directors may be removed with or without cause upon the affirmative vote of stockholders representing at least sixty-six and two-thirds percent (66<sup>2</sup>∕3%) of the voting power of the then outstanding shares of Voting Stock, at a meeting of our stockholders called for that purpose. "Affiliated Companies" in our charter means (a) Madison Dearborn Partners, LLC, Madison Dearborn Partners VI-A&C, L.P., Madison Dearborn Partners VI-B, L.P. and MDP Global Investors Limited (collectively, the "MDP Group"), (b) Walgreens Company, (c) any entity that controls, is controlled by or under common control with HC I, the MDP Group or Walgreens Company (other than us and any company that is controlled by us) and any investment funds managed by the MDP Group and (d) in respect of us, any company controlled by us.

Our charter provides that whenever the holders of one or more series of preferred stock has the right, voting separately or together with the holders of one or more other series, to elect directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and newly created directorships and other features of such directorship will be subject to the rights of such series of preferred stock. During any period when the holders of any series of preferred stock, voting separately as a series or together with one or more series, have the right to elect additional directors, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of our directors will automatically be increased by such specified number of directors, and the holders of such preferred stock will be entitled to elect the additional directors so provided for or fixed pursuant to said provisions, and (ii) each such additional director will serve until such director's successor has been duly elected and qualified, or until such director's right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, resignation, disqualification or removal.

Except as otherwise provided by the Board in the resolution or resolutions establishing such series, whenever the holders of any series of preferred stock having such right to elect additional directors are divested of such right pursuant to the provisions of such stock, the terms of office of all such additional directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, will forthwith terminate (in which case each such director thereupon will cease to be qualified as, and will cease to be, a director) and the total authorized number of our directors will automatically be reduced accordingly.

*Action by Written Consent*

Prior to the Trigger Date, any action which is required or permitted to be taken by our stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of our stock entitled to vote thereon were present and voted. From and after the Trigger Date, any action required or permitted to be taken by our stockholders may be taken only at a duly called annual or special meeting of our stockholders and the power of stockholders to consent in writing without a meeting is specifically denied; *provided, however*, that any action required or permitted to be taken by the holders of preferred stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without a vote, to the extent expressly so provided the resolutions creating such series of preferred stock.

*Special Meetings of Stockholders*

Subject to the rights of the holders of any series of preferred stock then outstanding and to the requirements of applicable law, special meetings of our stockholders held may be called only (i) by or at the direction of the Board or the Chairman of the Board pursuant to a written resolution adopted by the affirmative vote of the majority of the total number of directors that we would have if there were no vacancies or (ii) prior to the Trigger Date, by the Chairman of the Board of Directors at the written request of the holders of a majority of the voting power of the then outstanding shares of Voting Stock in the manner provided for in our bylaws.

*Certain Corporate Opportunities*

To the fullest extent permitted by applicable law, none of HC I and/or its Affiliated Companies and/or their respective directors, partners, principals, officers, members, managers and/or employees, including any of the foregoing who serve as our officers or directors (collectively, the "Exempted Persons") have any fiduciary duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as us or any of our Affiliated Companies, and no Exempted Person is liable to us or our stockholders for breach of any fiduciary duty solely by reason of any such activities of HC I, its Affiliated Companies or such Exempted Person. To the fullest extent permitted by applicable law, we, on our own behalf and our Affiliated Companies, renounces in our charter any interest or expectancy of us and our Affiliated Companies in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to the Exempted Persons, even if the opportunity is one that we or our Affiliated Companies might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each Exempted Person has no duty to communicate or offer such business opportunity to us or our Affiliated Companies and, to the fullest extent permitted by applicable law, is not liable to us, any of our Affiliated Companies or our stockholders for breach of any fiduciary or other duty, as our director, officer or stockholder solely, by reason of the fact that HC I, its Affiliated Companies or any such Exempted Person pursues or acquires such business opportunity, sells, assigns, transfers or directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to us or any of our Affiliated Companies. Notwithstanding anything to the contrary in Section 2 of Article Eight of our charter, we do not renounce any interest or expectancy we may have in (i) any business opportunity that is expressly offered to any Exempted Person solely in his or her capacity as our director or officer, and not in any other capacity, or (ii) any business opportunity that any Exempted Person first learns of in his or her capacity as our director or officer.

Subject to the rights of the holders of any series of preferred stock then outstanding, and in addition to any vote required by applicable law, the affirmative vote of the holders of at least eighty percent (80%) of the voting power of the then outstanding shares of Voting Stock, voting together as a single class, is required to alter, amend or repeal, or to adopt any provision inconsistent with, Article Eight of our charter; *provided however*, that, to the fullest extent permitted by law, neither the alteration, amendment or repeal of Article Eight nor the adoption of any provision of our charter inconsistent with Article Eight will apply to or have any effect on the liability or alleged liability of any Exempted Person for or with respect to any activities or opportunities which such Exempted Person becomes aware prior to such alteration, amendment, repeal or adoption.

*Advance Notice for Stockholder Proposals and Nominations*

Our bylaws contain provisions requiring advance notice be delivered to us of any business to be brought by a stockholder before an annual meeting and providing for procedures to be followed by stockholders in nominating persons for election to our Board of Directors, including stockholder nominees to be included in our proxy statement. A stockholder must give notice no later than the 90th day nor earlier than the 120th days before the one-year anniversary of the date on which we held our annual meeting of stockholders the previous year. The notice must contain the information required by our bylaws, and the stockholder(s) and nominee(s) must comply with the information and other requirements required by our bylaws.

*No Cumulative Voting*

The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our charter provides otherwise. Our charter does not provide for cumulative voting for our directors. The absence of cumulative voting may make it more difficult for stockholders owning less than a majority of our common stock to elect any directors to our Board.

*Approval of Business Combinations with Interested Stockholders*

We do not opt out of Section 203 of the DGCL in our charter, and thus are subject to Section 203 of the DGCL. In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date the person became an interested stockholder, unless the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a "business combination" includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Generally, an "interested stockholder" is a person that together with affiliates and associates, owns or within three years prior to the determination of interested stockholder status, did own, 15% or more of a corporation's voting stock. This may have an anti-takeover effect with respect to transactions not approved in advance by our Board, including discouraging attempts that might result in a premium over the market price for the shares of our common stock.

*Supermajority Voting Requirements to Amend Our Charter and Bylaws*

Subject to the rights of holders of any series of preferred stock then outstanding, notwithstanding any other provision of our charter or bylaws, and in addition to any affirmative vote of the holders of any particular class or series of the capital stock required by law or otherwise, no provision of Articles Five, Six, Seven, Nine or Ten of our charter may be altered, amended or repealed in any respect, nor may any provision of our charter or bylaws inconsistent therewith be adopted, unless in addition to any other vote required by our charter or otherwise required by law, (i) prior to the Trigger Date, such alteration, amendment, repeal or adoption is approved by the affirmative vote of the holders of a majority of the voting power of all outstanding shares of Voting Stock, voting together as a single class, and (ii) from and after the Trigger Date, such alteration, amendment, repeal or adoption is approved by the affirmative vote of holders of at least sixty-six and two-thirds percent (66<sup>2</sup>∕3%) of the voting power of all outstanding shares of Voting Stock, voting together as a single class, at a meeting of our stockholders called for that purpose. Additionally, as discussed above, Article Eight of our charter can only be amended by a vote of eighty percent (80%) of the voting power of the then outstanding shares of Voting Stock, voting together as a single class, subject to the limitations discussed above.

Subject to the rights of holders of any series of preferred stock then outstanding, in furtherance and not in limitation of the powers conferred by law, prior to the Trigger Date, our bylaws may be amended, altered or repealed and new bylaws made by (i) the Board or (ii) in addition to any vote of the holders of any class or series of our capital stock required in our charter (including any resolution or certificate of designations setting forth the terms of any series of preferred stock) and any other vote otherwise required by applicable law, the affirmative vote of the holders of at least a majority of the voting power of all of the then outstanding shares of Voting Stock, voting together as a single class. On and after the Trigger Date, our bylaws may be amended, altered or repealed and new bylaws made by (i) the Board or (ii) in addition to any of the holders of any class or series of our capital stock required herein (including any certificate of designation relating to any series of preferred stock), the bylaws or applicable law, the affirmative vote of the holders of at least sixty-six and two-thirds percent (66<sup>2</sup>∕3%) of the voting power of the then outstanding Voting Stock, voting together as a single class.

**Listing**

Our common stock is traded on the Nasdaq Global Select Market under the symbol "OPCH."

**Transfer Agent and Registrar**

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC.

**DESCRIPTION OF WARRANTS**

We may issue warrants to purchase any combination of our common stock, preferred stock or other securities. We may issue warrants independently or together with other securities. Warrants sold with other securities may be attached to or separate from the other securities. We will issue warrants under one or more warrant agreements between us and a warrant agent that we will name in the applicable prospectus supplement.

The applicable prospectus supplement will include specific terms relating to the offering. We will file the form of any warrant agreement with the SEC, and you should read the warrant agreement for provisions that may be important to you. The applicable prospectus supplement will include some or all of the following terms:

&nbsp;&nbsp;&nbsp;&nbsp;· the title of the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;· the aggregate number of warrants offered;

&nbsp;&nbsp;&nbsp;&nbsp;· the designation, number and terms of the common stock, preferred stock or other securities purchasable upon exercise of the warrants,
and procedures by which the number of securities purchasable may be adjusted, if any;

&nbsp;&nbsp;&nbsp;&nbsp;· the exercise price of the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;· the dates or periods during which the warrants are exercisable;

&nbsp;&nbsp;&nbsp;&nbsp;· the designation and terms of any securities with which the warrants are issued;

&nbsp;&nbsp;&nbsp;&nbsp;· if the warrants are issued as a unit with another security, the date on and after which the warrants and the other security will be
separately transferable, if ever;

&nbsp;&nbsp;&nbsp;&nbsp;· any minimum or maximum amount of warrants that may be exercised at any one time; and

&nbsp;&nbsp;&nbsp;&nbsp;· any terms, procedures and limitations relating to the transferability, exchange or exercise of the warrants.

**DESCRIPTION OF SUBSCRIPTION RIGHTS**

We may, at our option, issue subscription rights independently or together with any other security, which may or may not be transferable. As part of any rights offering, we may enter into a standby underwriting or other arrangement under which the underwriters or any other person would purchase any securities that are not purchased in such rights offering. If we issue subscription rights, they may be governed by a separate subscription agent agreement that we will sign with a bank or trust company, as rights agent, that will be named in the applicable prospectus supplement. The rights agent will act solely as our agent and will not assume any obligation to any holders of rights certificates or beneficial owners of rights.

In general, a right entitles the holder to purchase for cash a specific number of shares of common stock or other securities at a specified exercise price. The rights are normally issued to stockholders as of a specific record date, may be exercised only for a limited period of time and become void following the expiration of such period. If we determine to issue subscription rights, we will accompany this prospectus with a prospectus supplement that will describe, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;· the record date for stockholders entitled to receive the rights;

&nbsp;&nbsp;&nbsp;&nbsp;· the number of shares of common stock or other securities that may be purchased upon exercise of each right;

&nbsp;&nbsp;&nbsp;&nbsp;· the exercise price of the rights;

&nbsp;&nbsp;&nbsp;&nbsp;· whether the rights are transferable;

&nbsp;&nbsp;&nbsp;&nbsp;· the period during which the rights may be exercised and when they will expire;

&nbsp;&nbsp;&nbsp;&nbsp;· the steps required to exercise the rights;

&nbsp;&nbsp;&nbsp;&nbsp;· the price, if any, for the subscription rights;

&nbsp;&nbsp;&nbsp;&nbsp;· the number of subscription rights issued;

&nbsp;&nbsp;&nbsp;&nbsp;· the terms of the shares of common stock or shares of preferred stock or depositary shares;

&nbsp;&nbsp;&nbsp;&nbsp;· if applicable, the material terms of any standby underwriting or other arrangement entered into by us in connection with the offering
of subscription rights;

&nbsp;&nbsp;&nbsp;&nbsp;· the other terms of the subscription rights, including the terms, procedures and limitations relating to the exercise of the subscription
rights;

&nbsp;&nbsp;&nbsp;&nbsp;· whether the rights include "oversubscription rights" so that the holder may purchase more securities if other holders
do not purchase their full allotments;

&nbsp;&nbsp;&nbsp;&nbsp;· whether we intend to sell the shares of common stock or other securities that are not purchased in the rights offering to an underwriter
or other purchaser under a contractual "standby" commitment or other arrangement; and

&nbsp;&nbsp;&nbsp;&nbsp;· any applicable United States federal income tax considerations.

If fewer than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

**DESCRIPTION OF DEPOSITARY SHARES**

We may, at our option, elect to offer fractional shares of preferred stock, rather than single shares of preferred stock (to be set forth in the prospectus supplement relating to a particular series of preferred stock). In the event we elect to do so, depositary receipts evidencing depositary shares will be issued.

This description of the terms of depositary shares sets forth certain general terms and provisions of depositary shares to which any prospectus supplement may relate. The particular terms of the depositary shares offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to those depositary shares will be described in the prospectus supplement relating to those depositary shares. Accordingly, for a description of the terms of a particular issue of depositary shares, reference must be made to both the prospectus supplement relating thereto and this description.

The shares of any class or series of preferred stock represented by depositary shares will be deposited under a deposit agreement between us and one or more depositaries selected by us. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share, to all the rights and preferences of the shares of preferred stock represented by the depositary share, including dividend, voting, redemption and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of the related class or series of preferred shares in accordance with the terms of the offering described in the related prospectus supplement.

The applicable prospectus supplement will include specific terms relating to the offering. We will file the form of any deposit agreement with the SEC, and you should read the deposit agreement for provisions that may be important to you.

**DESCRIPTION OF UNITS**

As specified in the applicable prospectus supplement, we may issue units comprised of two or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The applicable prospectus supplement will describe:

&nbsp;&nbsp;&nbsp;&nbsp;· the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances
the securities comprising the units may be held or transferred separately;

&nbsp;&nbsp;&nbsp;&nbsp;· a description of the terms of any unit agreement governing the units;

&nbsp;&nbsp;&nbsp;&nbsp;· a description of the provisions for the payment, settlement, transfer or exchange of the units; and

&nbsp;&nbsp;&nbsp;&nbsp;· whether the units will be issued in fully registered or global form.

The unit agreement, together with the terms of the underlying securities, will be filed with the SEC in connection with the offering of the specific units. You should read such filings for provisions that may be important to you.

**PLAN OF DISTRIBUTION**

We and/or the selling stockholders, which as used herein includes donees, pledgees, transferees, assignees or other successors-in-interest selling our securities or interests in our securities received after the date of this prospectus from the selling stockholders as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of certain of their securities or interests in our securities, on any stock exchange, market or trading facility on which the security is traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

We and/or the selling stockholders may use any one or more of the following methods when disposing of securities or interests therein:

&nbsp;&nbsp;&nbsp;&nbsp;· on the NASDAQ Stock Market or any other national securities exchange or U.S. inter-dealer system of a registered national securities
association on which our securities may be listed or quoted at the time of sale;

&nbsp;&nbsp;&nbsp;&nbsp;· ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;· one or more underwritten offerings;

&nbsp;&nbsp;&nbsp;&nbsp;· block trades in which the broker-dealer will attempt to sell the securities as agent, but may position and resell a portion of the
block as principal to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;· purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

&nbsp;&nbsp;&nbsp;&nbsp;· an exchange distribution in accordance with the rules of the applicable exchange;

&nbsp;&nbsp;&nbsp;&nbsp;· privately negotiated transactions;

&nbsp;&nbsp;&nbsp;&nbsp;· short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;· through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;· broker-dealers may agree with the selling stockholders to sell a specified number of such securities at a stipulated price per share;
and

&nbsp;&nbsp;&nbsp;&nbsp;· a combination of any such methods of sale.

The selling stockholders may, from time to time, pledge or grant a security interest in some of the securities owned by them and, if the selling stockholders default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the securities, from time to time, under this prospectus, or under an amendment or supplement to this prospectus amending the list of the selling stockholders to include the pledgee, transferee, assignees or other successors-in-interest as the selling stockholders under this prospectus. The selling stockholders also may transfer the securities in other circumstances, in which case the donees, pledgees, transferees, assignees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of our securities or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of our securities in the course of hedging the positions they assume. The selling stockholders may also sell our securities short and deliver these securities to close out their short positions, or loan or pledge our securities to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to us and/or the selling stockholders from the sale of our securities will be the purchase price of our securities less discounts or commissions, if any. We and/or the selling stockholders reserve the right to accept and, together with their agents from time to time, as applicable, to reject, in whole or in part, any proposed purchase of our securities to be made directly or through agents. We will not receive any of the proceeds from any offering by the selling stockholders.

The selling stockholders also may in the future resell a portion of the securities in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule, or pursuant to other available exemptions from the registration requirements of the Securities Act.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of our securities or interests therein may be "underwriters" within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the securities may be underwriting discounts and commissions under the Securities Act. If the selling stockholders are "underwriters" within the meaning of Section 2(11) of the Securities Act, then the selling stockholders will be subject to the prospectus delivery requirements of the Securities Act. Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with us and the selling stockholders, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

To the extent required, the securities to be sold, the respective purchase prices and public offering prices, the names of any agents, dealers or underwriters, and any applicable discounts, commissions, concessions or other compensation with respect to a particular offer will be set forth in an applicable prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

To facilitate the offering of the securities offered by us and/or the selling stockholders, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. This may include over-allotments or short sales, which involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of our securities by bidding for or purchasing such securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of our securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

The selling stockholders may use this prospectus in connection with resales of the securities as specified on the cover of this prospectus. The selling stockholders may be deemed to be underwriters under the Securities Act in connection with the securities they resell and any profits on the sales may be deemed to be underwriting discounts and commissions under the Securities Act. Unless otherwise set forth in a prospectus supplement, the selling stockholders will receive all the net proceeds from the resale of the securities sold by them.

If any legal matters relating to offerings made in connection with this prospectus are passed upon by counsel for underwriters, dealers or agents, such counsel will be named in the prospectus supplement relating to any such offering.
