FOURTH REMINDER - TAKE ACTION AND PROTECT YOUR INVESTMENT PARATEK PHARMACEUTICALS IF THE TRANSACTION IS NOT APPROVED YOUR INVESTMENT IN PARATEK IS AT RISK As you may know, Paratek Pharmaceuticals, Inc. (“Paratek”) previously announced a definitive agreement to be acquired by Gurnet Point Capital (“Gurnet Point”) and Novo Holdings A/S (“Novo Holdings”). The consequences of failing to approve the transaction, and leaving Paratek as a standalone company, will create near term liquidity needs and would likely result in substantial dilution of ALL stockholders or risk of bankruptcy. Join other Paratek stockholders in voting FOR the transaction. If you do not vote, it has the same effect as voting against the transaction. Time is running out - Vote your shares online today to ensure they are received in time. THE DEADLINE FOR YOUR ONLINE VOTE TO BE RECEIVED IS 11:59 PM ET ON SEPTEMBER 17, 2023. If the transaction is approved, stockholders will receive both an immediate cash payment of $2.15 per share plus a contingent value right of $0.85 per share payable upon the achievement of a net sales threshold for NUZYRA, representing an aggregate potential total value of $3.00 per share. The upfront cash payment at the closing of the transaction represents a premium of 41% over the closing price of our common stock as of May 31, 2023’. Every vote is important, no matter how many shares you own. Please vote your proxy today “FOR” the transaction. For Assistance in Voting Your Proxy, Please Contact Our Proxy Solicitor Morrow Sodali LLC Today at +1 (800) 662-5200 (toll-free in North America) +1 (203) 658-9400 (collect outside of North America) PRTK@info.morrowsodali.com ‘The last full trading day prior to market speculation regarding a potential sale of Paratek.
