Item 8.01 Other Events.

On December 8, 2017, a reverse merger transaction between Network Medical Management, Inc., a California corporation (“NMM”) and Apollo Medical Holdings, Inc., a Delaware corporation (the “Company”) was consummated such that NMM became a wholly-owned subsidiary of the Company (the “Merger”). Pursuant to the Merger, the shares of NMM common stock previously held by former NMM shareholders were converted into securities of the Company as previously disclosed in the Company’s SEC filings.

As a condition to the closing of the Merger, and as previously disclosed in the Company’s SEC filings, all of the former NMM shareholders were required to enter into a Lock-Up Agreement with the Company, dated December 6, 2017 (the “Lock-Up Agreements”). Under the terms of the Lock-Up Agreements, the former NMM shareholders agreed not to, without the prior written consent of the Company and except in limited circumstances (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of “Covered Securities” (as defined in the Lock-Up Agreement), or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Covered Securities. The lock-up restrictions terminate with respect to one-third of the shares of the Company’s common stock issued in connection with the Merger immediately following each of (i) the 18^th month anniversary of the effective time of the Merger (the “First Lock Up Period”), (ii) the 30^th month anniversary of the effective time of the Merger, and (iii) the 42^nd month anniversary of the effective time of the Merger. Pursuant to amendments to the Lock-Up Agreements entered into between the Company and the former NMM shareholders, the former NMM shareholders agreed to extend the expiration date of the First Lock-Up Period from June 7, 2019 to September 30, 2019, and thereafter, to further extend the expiration date of the First Lock-Up Period from September 30, 2019 to January 31, 2020. Except as described above, all the terms and conditions of the Lock-Up Agreements remain unchanged and in full force and effect. Therefore, in accordance with the Lock-up Agreements, the First Lock Up Period (as extended) ended at 12:01 a.m. on February 1, 2020, and such shares became freely tradable.

As a result, the Company estimates that 7,083,957 shares of the Company’s common stock became eligible for sale in the public market at the open of trading on February 3, 2020 (subject to trading limitations on shares held by officers, directors and affiliates of the Company, and restrictions under the Company’s insider trading policy).
