Item 8.01. Other Events.

On June 19, 2020, Tetraphase Pharmaceuticals, Inc. (“Tetraphase”) received an unsolicited proposal from La Jolla Pharmaceutical Company (“La Jolla”) to acquire Tetraphase for $43.0 million in cash, plus an additional $16.0 million in cash potentially payable under contingent value rights to be issued in the transaction (the “La Jolla Proposal”). Under the La Jolla Proposal, the upfront cash consideration would be paid as follows: (i) $2.00 per share of Tetraphase common stock (including common stock underlying restricted stock units, performance-based stock units and pre-funded warrants), (ii) $2.68 per share of Tetraphase common stock underlying the common stock warrants issued by Tetraphase in November 2019, and (iii) $2.69 per share of Tetraphase common stock underlying the common stock warrants issued by Tetraphase in January 2020.

Tetraphase previously announced that it had entered into a merger agreement, dated as of June 4, 2020 (the “Melinta Merger Agreement”), with Melinta Therapeutics, Inc. (“Melinta”) and Toronto Transaction Corp., a wholly-owned subsidiary of Melinta (“Purchaser”), pursuant to which Melinta would acquire Tetraphase through a cash tender offer by Purchaser for all of Tetraphase’s outstanding shares of common stock for (1) $1.79 per share of common stock, and (2) one contingent value right per share representing the right to receive certain consideration based on the achievement of net sales milestones in an aggregate amount of up to $16.0 million (the “Offer”).

On June 20, 2020, the board of directors of Tetraphase (the “Tetraphase Board”) determined in good faith, after consultation with its independent financial advisors and outside legal counsel, that the La Jolla Proposal could reasonably be expected to lead to a Superior Offer as defined in the Melinta Merger Agreement, and that the failure to (1) furnish, pursuant to an acceptable confidentiality agreement, information (including non-public information) to La Jolla, and (2) engage in or otherwise participate in discussions or negotiations with La Jolla in respect of the La Jolla Proposal could reasonably be expected to be inconsistent with the fiduciary duties of the Tetraphase Board to Tetraphase’s stockholders under applicable legal requirements. Accordingly, in accordance with the Melinta Merger Agreement, the Tetraphase Board determined to consider the La Jolla Proposal, to enter into discussions and/or negotiations with respect to the La Jolla Proposal and, subject to an acceptable confidentiality agreement, to furnish non-public information to La Jolla.

On June 21, 2020, the Tetraphase Board determined in good faith, after consultation with its independent financial advisors and outside legal counsel, that the La Jolla Proposal to acquire Tetraphase is a “Superior Offer” under the terms of the Melinta Merger Agreement. In connection with this determination and in accordance with the terms of the Melinta Merger Agreement, Tetraphase has given notice to Melinta of such determination and of its intention to consider changing its recommendation of the Offer and the Melinta Merger Agreement or terminating the Melinta Merger Agreement unless Melinta proposes revisions to the terms of the Melinta Merger Agreement or makes another proposal on or prior to Friday, June 26, 2020 that, if accepted, would result in the La Jolla Proposal ceasing to be a Superior Offer.

A copy of the press release announcing these developments is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

There can be no assurances that any definitive agreement or transaction will result from the La Jolla Proposal or Tetraphase’s discussions with La Jolla. At this time, the Tetraphase Board (1) continues to recommend the Offer under the Melinta Merger Agreement to its stockholders, (2) is not modifying or withdrawing its recommendation with respect to the Offer under the Melinta Merger Agreement, or proposing to do so, and (3) is not making any recommendation with respect to the La Jolla Proposal.

Janney Montgomery Scott LLC is acting as financial advisor to Tetraphase and Wilmer Cutler Pickering Hale and Dorr LLP is acting as legal advisor.

Additional Information and Where to Find it

The tender offer by a subsidiary of Melinta for the outstanding shares of Tetraphase referenced in this Current Report on Form 8-K commenced on June 12, 2020. This Current Report on Form 8-K is for informational purposes only and is neither an offer to purchase nor a solicitation of an offer to sell any securities, nor is it a substitute for the


tender offer materials that Tetraphase, Melinta and its subsidiary have filed with the Securities and Exchange Commission (“SEC”). On June 12, 2020, Melinta filed with the SEC a Tender Offer Statement on Schedule TO and Tetraphase filed with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9. Tetraphase and Melinta also plan to file other relevant documents with the SEC regarding the proposed transaction. The tender offer materials (including an Offer to Purchase, a related Letter of Transmittal and certain other tender offer documents) and the Solicitation/Recommendation Statement contain important information. Holders of shares of Tetraphase Common Stock are urged to read the tender offer materials (including the Offer to Purchase, the related Letter of Transmittal and certain other tender offer documents included in the Tender Offer Statement) and the Solicitation/Recommendation Statement and other relevant documents filed with the SEC carefully and in their entirety because they contain important information that holders of shares of Tetraphase Common Stock should consider before making any decision regarding tendering their shares. The Tender Offer Statement and the Solicitation/Recommendation Statement are available for free at the SEC’s website at www.sec.gov. Free copies of these materials and other tender offer documents will be made available by the information agent for the tender offer.

In addition to the Offer to Purchase, the related Letter of Transmittal and certain other tender offer documents, as well as the Solicitation/Recommendation Statement, Tetraphase, Melinta and La Jolla file or filed annual, quarterly and special reports, proxy statements and other information with the SEC. These filings with the SEC are available to the public from the website maintained by the SEC at www.sec.gov. Additional copies of the tender offer materials may be obtained for free by contacting Melinta Therapeutics, Inc. at 44 Whippany Rd, Suite 280, Morristown, New Jersey 07960, Attention: Legal.

If a negotiated transaction between Tetraphase and La Jolla is agreed, Tetraphase and La Jolla will prepare filing(s) related to the proposed transaction (such as a tender offer statement on Schedule TO, including an offer to purchase, a related letter of transmittal and other tender offer documents related to the transaction and any amendments thereto, and Tetraphase would file a recommendation statement on Schedule 14D-9 with the SEC and any amendments thereto), and Tetraphase will provide the filing(s) to its stockholders. Tetraphase, and possibly La Jolla, may also file other documents with the SEC regarding the proposed transaction. This document is not a substitute for any tender offer document or any other document which Tetraphase or La Jolla may file with the SEC in connection with the proposed transaction. If a negotiated transaction between Tetraphase and La Jolla is agreed, investors and security holders are urged to read the filing(s) and the other relevant materials with respect to the proposed transaction with La Jolla carefully in their entirety when they become available before making any voting or investment decision with respect to any proposed transaction with La Jolla, because they will contain important information about any proposed transaction with La Jolla.
