2025 Stockholder Proposals or Director Nominations

For matters to be included in the proxy materials for our 2025 Annual Meeting, excluding director nominations, submissions must be received on or before the close of business on December 4, 2024. All proposals must comply with Rule 14a-8 under the Exchange Act.

Matters for consideration at our 2025 Annual Meeting but not for inclusion in our proxy materials must be submitted no earlier than the close of business on January 15, 2025 and no later than the close of business on February 14, 2025. The proposal must come from a stockholder of record and include the information required by our By-laws. If you are a beneficial owner of shares held in street name, contact the organization that holds your shares for details about how to register your shares directly in your name as a stockholder of record.

In 2023, we implemented a proxy access by-law allowing a stockholder or a group of up to 20 stockholders, owning continuously for at least three years shares of our stock representing an aggregate of at least 3% of our outstanding shares, to nominate and include in our proxy materials director nominees constituting up to 20% of the Board, provided that the stockholder(s) and nominee(s) satisfy the requirements in our By-laws. Notice of proxy access director nominees must be received between the close of business on November 4, 2024 and the close of business on December 4, 2024.

Under our By-laws, stockholders intending to nominate directors at our 2025 Annual Meeting (other than through proxy access as described above) must submit notice to us no earlier than the close of business on January 15, 2025 and no later than the close of business on February 14, 2025. Notice of director nominations must be submitted by a stockholder of record and satisfy the requirements in our By-laws. If you are a beneficial stockholder, contact the organization that holds your shares for details about how to register your shares directly in your name as a stockholder of record. In addition to satisfying the foregoing requirements, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Board’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 17, 2025.

Proposals and director nominations must be sent by mail to our Corporate Secretary at 3000 Lakeside Drive #300N, Bannockburn, Illinois 60015, or by e-mail to OCH-CorporateSecretary@optioncare.com. Our By-laws have been filed with the SEC and are available without charge on the SEC’s website atwww.sec.gov.

Notice of Internet Availability

We primarily use the Internet to provide proxy materials to our stockholders. We are sending a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”) to our stockholders with instructions on how to access the proxy materials online atwww.proxyvote.com or to request a printed copy of the materials.

Stockholders can follow the instructions in the Notice of Internet Availability to choose to receive future proxy materials in print by mail or electronically by e-mail. We encourage stockholders to use the online availability of proxy materials to help reduce the environmental impact of our annual meetings of stockholders and lower our printing and mailing costs. Our proxy materials are also available atinvestors.optioncarehealth.com.

Stockholders Sharing the Same Address

We have implemented a process known as “householding.” Under this process, we may send a single copy of the Notice of Internet Availability and, if you have requested printed versions by mail, this Proxy Statement and the 2023 Annual Report, to multiple stockholders who share the same address, unless we have received different instructions from any of the stockholders. This method helps reduce the environmental impact of our annual stockholder meetings and lowers our printing and mailing costs. Stockholders who participate in householding will still receive separate proxy cards. If a stockholder chooses not to participate in householding, they can request a separate copy of the Notice of Internet Availability and, if they requested printed versions by mail, this Proxy Statement and the 2023 Annual Report, which we will promptly deliver upon request.

To receive a separate copy of the Notice of Internet Availability and, if you requested printed versions by mail, this Proxy Statement or the 2023 Annual Report, or separate copies of any future notice, proxy statement, or annual reports at no charge, you may send notice to Option Care Health, Inc., 3000 Lakeside Drive #300N, Bannockburn, IL 60015 USA, Attention: Investor Relations or call (312) 940-2538. If you are receiving multiple copies of proxy materials at one address and wish to participate in householding, please contact the bank, broker or other organization holding your shares to inquire about eliminating duplicate mailings.

Legal Matters

This Proxy Statement may contain “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “anticipate,” “intend,” “plan,” “believe,” “project,” “estimate,” “expect,” “may,” “should,” “will” and similar references to future periods. Examples of forward-looking statements include, among others, statements regarding our ESG program and our executive compensation program.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. For a detailed discussion of the risks that could affect our actual results, please refer to the risk factors identified in our periodic reports as filed with the SEC.

Any forward-looking statement made in this Proxy Statement is based on information available to us as of the date of this Proxy Statement and speaks only as of such date. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.

Website references in this document are provided for convenience only, and the content on the referenced websites is not incorporated herein by reference and does not constitute a part of this Proxy Statement.

Other Matters

We are not aware of any additional matters to be presented at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, the individuals named in the accompanying proxy intend to vote on them in accordance with their best judgment.
