-- NUZYRA Generated Net U.S. Sales of $12.4 Million in the Fourth Quarter 2020; a 14% Increase Over the Third Quarter 2020

-- NUZYRA Expansion into the Primary Care Setting in 2021

-- Paratek Expects Full Year 2021 Total Revenue Between$166and$177Million

BOSTON, Feb. 24, 2021 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (Nasdaq: PRTK), a commercial-stage biopharmaceutical company focused on the development and commercialization of novel life-saving therapies for life-threatening diseases or other public health threats for civilian, government andmilitary use, today reported financial results and provided an update on corporate activities for the quarter and year ended December 31, 2020.

The launch of NUZYRA continued to demonstrate consistent quarter-over-quarter growth through 2020 in a challenging environment created by the ongoing COVID-19 pandemic, said Evan Loh, M.D., Chief Executive Officer at Paratek. The full year commercial net U.S. sales of NUZYRA, which landed at the high end of our guidance range, reflects the strong health of the underlying core commercial business. With two Biomedical Advanced Research and Development Authority (BARDA) Project BioShield procurements for the Strategic National Stockpile (SNS) now anticipated in 2021 plus the expected continued commercial growth of NUZYRA, we are anticipating a significant ramp up in total revenue for 2021. We believe prescribers recognize NUZYRA as an important life-saving antibiotic that addresses patient needs in the face of the growing global threat from antibiotic resistance.

In our conversations with clinicians over the past several years, it is clear there is a tremendous unmet need for a well-tolerated, once daily oral broad-spectrum antibiotic that includes coverage against MRSA for skin infections. Current generic antibiotic options are universally challenged by either significant bacterial resistance or serious safety concerns that limit their clinical utility, said Adam Woodrow, Parateks President and Chief Commercial Officer. NUZYRAs product profile makes it a very attractive treatment option for community use. With access now solidly established with the payers and significant support from infectious disease specialists, we believe our primary care expansion will accelerate and strengthen our sales trajectory, especially as we enter the second half of 2021.Key 2021 Priorities

-- Expansion of NUZYRA into Primary Care Setting: Paratek completed the hiring of approximately 40 U.S. sales representatives in February 2021 to enable the expansion of the NUZRYA launch into the primary care setting. The Company expects to execute this expansion within its previously communicated cash runway guidance. -- NTM Rare Disease Opportunity: The Company plans to initiate a Phase 2b study, as early as mid-2021, to explore the potential utility of omadacycline as a treatment for non-tuberculous mycobacteria (NTM) infections due to Mycobacterium abscessus (M. abscessus), a rare disease with currently no approved therapies. M. abscessus and based on Company estimates represents a potential $1.0 billion addressable market opportunity in the U.S. -- Continued Progress of the BARDA Project BioShield Anthrax Program: The Company expects to continue to execute and deliver on its contract with BARDA to develop NUZYRA for the treatment of pulmonary anthrax, a critical bioterrorism threat deemed important to national security by BARDA. These activities include advancing the U.S. onshoring of NUZYRA manufacturing and the continued execution of certain preclinical research activities supporting the pulmonary anthrax development program. Under Parateks five-year agreement with BARDA, the Company also anticipates two procurements of 2,500 treatment courses of NUZYRA each in 2021 for addition to the SNS.

Other Recent Highlights

-- In December 2020, Paratek entered into a $60 million non-recourse loan agreement with an affiliate of R-Bridge Healthcare Investment Advisory (the R-Bridge Loan) that will be repaid using (i) all proceeds of royalties from the Companys License and Collaboration Agreement with Zai Lab and (ii) an initial 2.5% revenue interest from the Companys U.S. net sales of NUZYRA (initial annual cap of $10 million). The net proceeds of the R-Bridge Loan, together with cash on hand, was used to prepay in full all obligations outstanding under the Companys Amended and Restated Loan and Security Agreement with Hercules Capital on December 31, 2020.

-- Full year 2020 total revenue Full year 2020 total revenue was$46.9million, an increase of 184% over full year 2019 total revenue.NUZYRA generated $38.8 million in net U.S. sales for the full year 2020, an increase of 237% over the full year 2019. The growth in NUZYRA sales in 2020 reflects the Companys continued commitment to strong execution and NUZYRAs attributes that address unmet needs in the marketplace despite the significant disruptions of patient traffic to physician offices and institutions throughout the ongoing COVID-19 pandemic.IntodaysCOVID-19environment, NUZYRAs ability to minimize hospitalstays with the oral formulation is especially relevant for many prescribers and a meaningful benefit for patients.Governmentcontract serviceand grantrevenuewas$6.7millionin 2020.No revenue was generatedfrom the BARDA contract in 2019 as it was executed in December of that year.Collaboration and royalty revenue of $1.5 million in 2020 is primarily comprised of royalties earned from SEYSARA sales in the U.S. Collaboration and royalty revenue of $5.0 million in 2019 includeda $3.0 million milestone earned from Zai Lab in addition to royalties earned from SEYSARA sales in the U.S.

Research and development(R&D)expenseswere $6.3 million for the fourthquarter of 2020, compared to $9.1 million forsame period in the prior year. R&D expenses were $23.9 million for the full year 2020, compared to $39.6 million in the prior year. The decrease in both periods is primarily the result of lower clinical study costs associated withcompletion of thePhase 2 UTI program in 2019, partially offset by an increase in expenses incurred under the BARDA contract andthird-partymanufacturing process scale-up to meet expected future demand for NUZYRA.

Selling, general and administrative(SG&A)expenseswere $24.3 million for thefourth quarter of 2020, compared to $21.3millionfor thesame period in the prior year. The $3.0 million increase is primarily due to costs incurred to realign our hospital territories and our community expansion.

SG&A expenses were $89.9 million for the full year 2020, compared to $89.1 million in the prior year. The $0.8 million increase is primarily the result of costs for the Companys contract sales organization and higher product distribution fees, partially offset by lower marketing and promotional program expenses, personnel-related costs and travel due to the COVID-19 pandemic.

Paratek reported a net loss of $25.0million, or ($0.54) per share, for thefourthquarter of 2020, compared to a net loss of $27.4million, or ($0.81) per share, for the same period in 2019.
