Dear _______________,

Today we at Paratek Pharmaceuticals announced some important news – we’ve entered into an agreement to be acquired by an entity affiliated with Gurnet Point Capital (GPC), a private equity firm headquartered in Cambridge, Mass. and Novo Holdings (Novo), a holding and investment company responsible for managing the assets and wealth of the Novo Nordisk Foundation. The transaction is subject to regulatory review and other customary closing conditions and is expected to occur in the third quarter of 2023.

You can read more in this press release the company issued.

We are establishing a strong path for the future of Paratek and NUZYRA with this transaction. Importantly, GPC and Novo share in our confidence in NUZYRA and passion for generating positive patient outcomes. Paratek is confident in GPC’s and Novo’s commitment to providing resources to enhance our ability to deliver NUZYRA to more patients and ensure continued success.

Until the close of the transaction, Paratek, GPC and Novo will continue to operate as separate, independent companies and it remains business as usual.

As always, please do not hesitate to reach out if you have any questions.

We look forward to continuing to work with you to as we enter this next chapter.

Sincerely,
