INTRODUCTION

This Amendment No. 5 (this “Final Amendment”), which amends and supplements the Rule 13E-3 Transaction Statement on Schedule 13E-3 filed on June 30, 2023 with the Securities and Exchange Commission (the “SEC”) (as amended by Amendment No. 4 filed with the SEC on September 18, 2023, Amendment No. 3 filed with the SEC on September 11, 2023, Amendment No. 2 filed with the SEC on August 3, 2023 and Amendment No. 1 filed with the SEC on July 28, 2023, the “Schedule 13E-3” or “Transaction Statement”), is being filed with the SEC pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”), jointly by the following persons (each, a “Filing Person,” and collectively, the “Filing Persons”): (i) Paratek Pharmaceuticals, Inc. (the “Company”), a Delaware corporation and the issuer of the common stock, par value $0.001 per share (the “Company Common Stock”), that is subject to the Rule 13e-3 transaction, (ii) GPC WH Fund LP, a Delaware limited partnership (the “Guarantor”); (iii) Resistance GP LLC, a Delaware limited liability company (“Resistance GP”); (iv) Novo Holdings A/S, a Danish limited liability company (“Novo Holdings”); (v) Resistance TopCo L.P. a Delaware limited partnership (“TopCo”); (vi) Resistance Holdings, Inc., a Delaware corporation (“Resistance Holdings”); (vii) Resistance Intermediate, Inc., a Delaware corporation (“Resistance Intermediate”); (viii) Resistance Acquisition, Inc., a Delaware corporation (“Parent”); (ix) Resistance Merger Sub, Inc., a Delaware corporation (“Merger Sub” and, together with the Guarantor, Resistance GP, Novo Holdings, TopCo, Resistance Holdings, Resistance Intermediate and Parent, the “Parent Entities”); and (x) Evan Loh. The Parent Entities are Filing Persons of this Transaction Statement because they may be deemed to be affiliates of the Company under a possible interpretation of the SEC rules governing “going-private” transactions.

On June 6, 2023, Parent, Merger Sub and the Company entered into an Agreement and Plan of Merger (as amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), which provides for, among other things, the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a direct wholly-owned subsidiary of Parent. On August 2, 2023, the Company filed with the SEC a definitive proxy statement (the “Proxy Statement”) under Regulation 14A of the Exchange Act, relating to a special meeting of the stockholders of the Company held on September 18, 2023 (the “Special Meeting”) at which the stockholders of the Company voted to approve and adopt the Merger Agreement and voted to approve certain items of compensation that are based on or otherwise related to the Merger and may become payable to certain named executive officers of the Company under existing agreements with the Company. A copy of the Proxy Statement is attached hereto as Exhibit (a)(2)(i). A copy of the Merger Agreement is attached as Annex A to the Proxy Statement and incorporated herein by reference.

The cross-references below are being supplied pursuant to General Instruction G to Schedule 13E-3 and show the location in the Proxy Statement of the information required to be included in response to the items of Schedule 13E-3. Pursuant to General Instruction F to Schedule 13E-3, the information contained in the Proxy Statement, including all appendices thereto, is incorporated in its entirety herein by reference, and the responses to each item in this Schedule 13E-3 are qualified in their entirety by the information contained in the Proxy Statement and the appendices thereto.

Capitalized terms used but not expressly defined in this Schedule 13E-3 shall have the respective meanings given to them in the Proxy Statement.

The information concerning the Company contained in, or incorporated by reference into this Schedule 13E-3 and the Proxy Statement was supplied by the Company. Similarly, all information concerning each other Filing Person contained in, or incorporated by reference into this Schedule 13E-3 and the Proxy Statement was supplied by such Filing Person. No Filing Person, including the Company, is responsible for the accuracy of any information supplied by any other Filing Person.

While each of the Filing Persons acknowledges that the Merger is a “going private” transaction for purposes of Rule 13E-3 under the Exchange Act, the filing of this Transaction Statement shall not be construed as an admission by any Filing Person, or by any affiliate of a Filing Person, that the Company is “controlled” by any Filing Person.

This Final Amendment is being filed pursuant to Rule 13e-3(d)(3) under the Exchange Act to report the results of the transaction that is the subject of this Transaction Statement. Except as otherwise set forth below, the information set forth in this Schedule 13E-3 remains unchanged. This Final Amendment is being filed to reflect certain updates as reflected below.

(c) Other Material Information. The information set forth in response to Item 1011(c) of Regulation M-A is hereby amended and supplemented as follows:

On September 21, 2023, Parent filed a Certificate of Merger with the Office of the Secretary of State of the State of Delaware, pursuant to which the Merger became effective and Merger Sub was merged with and into the Company, with the Company continuing as the surviving corporation in the Merger. As a result of the Merger, the Company became a wholly-owned subsidiary of Parent.

At the Effective Time of the Merger (the “Effective Time”), each share of Company Common Stock, other than as provided below, was converted into the right to receive (x) $2.15, payable to the holder thereof in cash, without interest (the “Cash Consideration”) but subject to reduction for any applicable withholding taxes payable in respect thereof and (y) one contractual contingent value right (a “CVR”) that represents the right to receive $0.85 upon the satisfaction of certain conditions, pursuant to a Contingent Value Rights Agreement entered into between Parent and a rights agent selected by Parent and reasonably acceptable to the Company (the Cash Consideration and one CVR, collectively, the “Merger Consideration”). The following Company Common Stock was not converted into the right to receive the per share Merger Consideration in connection with the Merger: (i) each share held in the treasury of the Company or owned by the Company or any direct or indirect wholly-owned subsidiary of the Company and each share owned by Parent, Merger Sub or any direct or indirect wholly-owned subsidiary of Parent or Merger Sub immediately prior to the Effective Time or (ii) Company Common Stock outstanding immediately prior to the Effective Time and held by stockholders who are entitled to demand, and properly demand, appraisal for such Company Common Stock in accordance with Section 262 of the Delaware General Corporation Law.

As a result of the Merger, the Company’s shares have ceased to trade on Nasdaq and became eligible for delisting from Nasdaq and termination of registration under the Exchange Act. The Company has requested that Nasdaq file with the SEC a notification of removal from listing on From 25 with respect to the delisting of the shares from Nasdaq. The Company intends to file with the SEC a certification on Form 15 to terminate or suspend its reporting obligations under Sections 13(a) and 15(d) of the Exchange Act.
