Item 1. Security and Issuer.

This Amendment No. 2 (“Amendment No. 2”) amends and supplements the Schedule 13D/A filed with Securities and Exchange Commission (the “SEC”) by each of the undersigned Reporting Persons on November 20, 2017. Except as specifically provided herein, this Amendment No. 2 does not modify any of the information previously reported in the Schedule 13D/A. The principal executive offices of ADMA Biologics, Inc. (the “Issuer”) are located at 465 State Route 17, Ramsey, New Jersey.

Item 3. Source and Amount of Funds or Other Consideration.

On January 21, 2017, the Issuer and its wholly-owned subsidiary (the “Buyer”) entered into a definitive Master Purchase and Sale Agreement (the “Purchase Agreement”) with BPC, and for certain limited purposes set forth in the Purchase Agreement, Biotest AG (“Biotest”), pursuant to which Buyer agreed to acquire certain assets and assume certain liabilities constituting the therapy business of Biotest Pharmaceuticals Corporation (“BPC”). On June 6, 2017, following the satisfaction of all conditions to closing, including the approval of the stockholders of the Issuer, the transactions (the “Transaction”) contemplated by the Purchase Agreement were consummated.

The Transaction included the issuance to BPC, as part of the consideration for the Transaction, of an aggregate equity interest in the Issuer equal to fifty (50%), less one (1) share, of the issued and outstanding Issuer capital stock consisting of (a) 4,295,580 shares of the Issuer’s common stock, $0.0001 par value per share (the “Common Stock”), representing, at the time of the Transaction, twenty-five percent (25%) of the issued and outstanding Common Stock of the Issuer, which Common Stock is registered under the Securities Exchange Act of 1934, as amended, and (b) 8,591,160 shares of the Issuer’s non-voting common stock, $0.0001 par value per share (the “Non-Voting Common Stock”), which is convertible into Common Stock upon the occurrence of certain specified events which have not occurred as of the date of filing of this Schedule 13D/A.

On November 9, 2017, BPC purchased 5,813,954 shares of Common Stock of the Issuer in the Issuer’s public offering. Such shares of Common Stock were purchased for aggregate consideration of $12,500,001.10. The source of the funds to purchase 5,813,954 shares of Common Stock was working capital of the Reporting Person.

On May 14, 2018, the Issuer and its two wholly-owned subsidiaries, ADMA BioManufacturing, LLC, a Delaware limited liability company (“ADMA BioManufacturing”), and ADMA Bio Centers Georgia Inc., a Delaware corporation (“ADMA BioCenters”), entered into a Share Transfer, Amendment and Release Agreement with BPC, Biotest, Biotest US Corporation and The Biotest Divestiture Trust (the “Biotest Trust”) (the “Biotest Transfer Agreement”). Pursuant to the Biotest Transfer Agreement, BPC transferred to the Issuer, for no cash consideration, 8,591,160 shares of the Non-Voting Common Stock previously issued to BPC at an aggregate valuation of approximately $31.4 million, or $3.66 per share, in connection with the Transaction and representing 100% of the Issuer’s issued and outstanding Non-Voting Common Stock (the “NV Biotest Shares”). Immediately upon transfer of the NV Biotest Shares to the Issuer, the shares were retired and are no longer available for issuance. The retired NV Biotest Shares comprised approximately 19% of the Issuer’s total outstanding common stock as of May 14, 2018.

Item 4. Purpose of Transaction.

The purpose of the Transaction was for the Reporting Person to acquire a substantial voting and equity interest in the Issuer in exchange for the assets described herein and to enter into certain other agreements between the parties.

The purpose of the purchase of 5,813,954 shares of Common Stock in the Issuer’s public offering was to satisfy the Reporting Person’s contractual obligation with the Issuer, as described in the Purchase Agreement.

The purpose of the transfer by BPC of 8,591,160 shares of the Non-Voting Common Stock was to provide consideration to the Issuer for (i) granting to Biotest and BPC and their successors and assigns a release from all potential past, present and future indemnity claims arising under the Purchase Agreement; and (ii) relinquishing its rights pursuant to that certain Purchase Agreement, dated as of June 6, 2017, by and among the Issuer, ADMA BioCenters and BPC, to repurchase its two U.S. Food and Drug Administration approved plasma collection centers.

Item 5. Interest in Securities of the Issuer.

(a) The aggregate percentage of shares of Common Stock reported owned by the Reporting Person named herein is based upon a total of 36,726,084 shares of Common Stock outstanding as of May 14, 2018.

(b) BPC has the sole power to vote and dispose of the shares of Common Stock directly beneficially owned by it.

(c) Except as set forth herein and elsewhere in this Schedule 13D, there have been no other transactions in the class of securities reported on that were effected within the past sixty days.

(d) Not applicable.

(e) Not applicable.
