To the extent required by Item 3.03 of Form 8-K, the information regarding the reverse stock split contained in Item 5.03 and Item 8.01 of this Current Report on Form 8-K is incorporated by reference herein.

On January 30, 2020, as approved as described below under Item 8.01, Option Care Health, Inc. (the “Company”) filed a certificate of amendment to its certificate of incorporation (the “Certificate of Amendment”) with the Secretary of State of the State of Delaware to effect a reverse stock split of the Company’s common stock at a ratio of 1-for-4, effective on February 3, 2020.

The Certificate of Amendment is filed as Exhibit 3.1 to this Current Report on Form 8-K.

The Company’s board of directors has determined to set the reverse stock split ratio at 1-for-4. The effective date of the reverse stock split is February 3, 2020. The shares began trading on a split-adjusted basis at market open on February 3, 2020.

Upon the effectiveness of the reverse stock split on February 3, 2020, every four shares of the issued and outstanding shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), were automatically combined and reclassified into one issued and outstanding share of the Company’s Common Stock. The reverse stock split does not affect any stockholder’s ownership percentage of the Company’s Common Stock, alter the par value of the Company’s Common Stock or modify any voting rights or other terms of the Company’s Common Stock.

In connection with the reverse stock split, at the market open on February 3, 2020, the Company’s Common Stock began trading on the Nasdaq Global Select Market under the symbol “OPCH”. The Common Stock was assigned a new CUSIP number (68404L 201) and began trading on a split-adjusted basis.

On February 3, 2020, the Company issued a press release announcing the foregoing. A copy of the press release is filed as Exhibit 99.1 to this Current Report on Form 8-K.
