Mr. Spencer added, "Our COVID-19 collaborations have advanced significantly in recent months with multiple partners targeting emergency use authorization in the second half of 2021. The emerging portfolio of product opportunities with CpG 1018 has the potential to drive significant revenue growth in 2021 and beyond. Through the continued advancement of our multiple collaborations, CpG 1018 could be utilized in up to 500 million to 1.5 billion doses of vaccine annually starting in 2022, with additional capacity expansion available depending on global demand."

• Full year 2020 net product revenue of $36.0 million compared to $34.6 million for full year 2019, a 4% year-over-year growth rate despite the substantial ongoing reduction in market utilization due to the pandemic and COVID-19 vaccine rollout.
• Net product revenue for HEPLISAV-B during the fourth quarter 2020 was $11.5 million, up 8.5% year-over-year from $10.6 million for the fourth quarter of 2019.
• Market share in accounts targeted by the field sales team increased to 26%, up from 20% market share in the fourth quarter of 2019.
• Received Marketing Authorization in February 2021 from the European Commission following the positive opinion in December 2020 from the European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP).
• Reported final immunogenicity data from a study in adults with end-stage renal disease (ESRD) undergoing hemodialysis. In this study of 119 patients, HEPLISAV-B demonstrated a high seroprotection rate of 89.3% at week 20 after 4 standard doses.

CpG 1018 (Advanced Vaccine Adjuvant)

• Dynavax is scheduled to supply CpG 1018 to produce up to 100 million doses of Valneva's SE adjuvanted COVID-19 vaccine in 2021, which would generate CpG 1018 revenue of up to $230 million in 2021, contingent on the continued success of Valneva's vaccine candidate.
• First quarter 2021 CpG revenue is anticipated to be between $40 million and $60 million.
• Clover Biopharmaceuticals is initiating a global Phase 2/3 efficacy trial with their protein sub–unit COVID-19 vaccine candidate adjuvanted with CpG 1018 with an interim analysis for vaccine efficacy expected in the middle of 2021.
• Coalition for Epidemic Preparedness Innovations (CEPI) agreed to provide funding of up to $99 million for advanced manufacturing of CpG 1018 for use in COVID–19 vaccines developed by CEPI grantees to ensure product availability in 2021 upon emergency use authorization.

Total Revenues and Product Revenue, Net. Total revenues for the fourth quarter of 2020 were $19.6 million, including $13.1 million of net product revenue. Total revenues for 2020 were $46.6 million compared to $35.2 million for 2019. HEPLISAV-B product revenue, net increased to $11.5 million in the fourth quarter of 2020 compared to $10.6 million in the same period in 2019. Full year product revenue, net for HEPLISAV-B in 2020 was $36.0 million compared to $34.6 million for the full year 2019. CpG 1018 product revenue, net was $1.6 million in the fourth quarter of 2020 compared to $0.0 million in the same period in 2019. Full year product revenue, net for CpG 1018 in 2020 was $3.3 million compared to $0.0 million for the full year 2019.

Cost of Sales - Product. Cost of sales - product for the fourth quarter 2020 increased to $4.1 million, compared to $2.4 million for the fourth quarter of 2019. Full year 2020 cost of sales - product was $11.4 million compared to $10.2 million for the full year 2019. The increase was primarily due to higher unit costs for HEPLISAV-B as we produce and then sell inventory that reflects the full cost of manufacturing. For the six months ended December 31, 2020, cost of sales-product included $1.4 million of costs to produce CpG 1018 for our collaboration partners. The Company anticipates cost of sales - product to increase substantially in 2021 due to increased manufacturing of CpG 1018 under the supply agreement with Valneva.

Research and Development Expenses. Research and development (R&D) expenses for the fourth quarter of 2020 decreased to $9.5 million, compared to $12.3 million for the fourth quarter of 2019. Full year 2020 R&D expenses were $28.6 million compared to $62.3 million for the full year 2019. The decrease in R&D expenses is due to personnel costs, facilities overhead cost allocations and non-cash stock-based compensation decreases due to lower R&D headcount resulting from our restructuring in May 2019 and the winding down of our immuno-oncology programs and an increase of additional CpG 1018 development costs at our third-party manufacturing facility to support increased CpG 1018 demand from our collaboration partners for use in their development and/or commercialization of COVID-19 vaccines.

SG&A Expenses. Selling, general and administrative (SG&A) expenses for the fourth quarter of 2020 decreased to $17.8 million, compared to $20.3 million for the fourth quarter of 2019. Full year 2020 SG&A expenses were $79.3 million compared to $75.0 million for the full year 2019.

Loss from Operations and Net Income Loss. Loss from operations for the fourth quarter of 2020 decreased to $11.9 million from $27.4 million in the fourth quarter of 2019. Full year 2020 loss from operations decreased to $68.4 million compared to $134.8 million for the full year 2019. Net loss for the fourth quarter of 2020 was $15.5 million compared to a net loss of $36.8 million for the fourth quarter of 2019. Basic and diluted net loss per share was $0.14 for the fourth quarter of 2020, compared to $0.44 per basic and diluted net loss per share in the fourth quarter of 2019. Full year 2020 net loss decreased to $75.2 million or $0.75 per basic and $0.78 per diluted share compared to $152.6 million or $2.16 per basic and diluted share for the full year 2019.

In adults, hepatitis B is spread through contact with infected blood and through unprotected sex with an infected person. The U.S. Centers for Disease Control (CDC) recommends vaccination for those at high risk for infection due to their jobs, lifestyle, living situations and travel to certain areas.ⁱⁱ Because people with diabetes are particularly vulnerable to infection, the CDC recommends vaccination for adults age 19 to 59 with diabetes as soon as possible after their diagnosis, and for people age 60 and older with diabetes at their physician's discretion.ⁱⁱⁱ Approximately 20 million U.S. adults have diabetes, and 1.5 million new cases of diabetes are diagnosed each year.^iv

Do not administer HEPLISAV-B to individuals with a history of severe allergic reaction (e.g., anaphylaxis) after a previous dose of any hepatitis B vaccine or to any component of HEPLISAV-B, including yeast. Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of HEPLISAV-B. Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to HEPLISAV-B. Hepatitis B has a long incubation period. HEPLISAV-B may not prevent hepatitis B infection in individuals who have an unrecognized hepatitis B infection at the time of vaccine administration. The most common patient reported adverse reactions reported within 7 days of vaccination were injection site pain (23% to 39%), fatigue (11% to 17%) and headache (8% to 17%).

CpG 1018 is the adjuvant used in HEPLISAV-B® [Hepatitis B Vaccine (Recombinant), Adjuvanted], an adult hepatitis B vaccine approved by the U.S. Food and Drug Administration (FDA). Dynavax developed CpG 1018 to provide an increased vaccine immune response, which has been demonstrated in HEPLISAV-B. CpG 1018 provides a well- developed technology and a significant safety database, potentially accelerating the development and large-scale manufacturing of a COVID-19 vaccine.

Dynavax is a commercial stage biopharmaceutical company developing and commercializing novel vaccines. The Company's first commercial product, HEPLISAV-B® [Hepatitis B Vaccine (Recombinant), Adjuvanted], is approved in the U.S. for prevention of infection caused by all known subtypes of hepatitis B virus in adults age 18 years and older. Dynavax is also advancing CpG 1018 as a premier vaccine adjuvant through research collaborations and partnerships. Current collaborations are focused on adjuvanted vaccines for COVID-19, pertussis and universal influenza. For more information, visit www.dynavax.com and follow the company on LinkedIn.
