CpG 1018® Adjuvant Supply for COVID-19 Vaccines

Dynavax has established a global portfolio of CpG 1018 adjuvant commercial supply agreements (CSA) currently focused on the development of COVID-19 vaccines across a variety of vaccine platforms.

• CpG 1018 adjuvant revenue for the second quarter of 2022 was $222.6 million, up 471% compared to $39.0 million for the second quarter of 2021.
• The Company now expects 2022 full-year CpG 1018 adjuvant COVID-19 supply revenue to be between $550 million and $600 million, based on committed orders, with an anticipated full-year gross margin of approximately 60%.

Clinical Pipeline

Dynavax is advancing a pipeline of differentiated product candidates that leverage its CpG 1018 adjuvant, which has demonstrated its ability to enhance the immune response with a favorable tolerability profile in a wide range of clinical trials and real-world commercial use.

• Tetanus, diphtheria and pertussis (Tdap) vaccine program: Previously reported interim adult data from an on-going Phase 1 clinical trial evaluating the Company's adjuvanted Tdap vaccine candidate demonstrated it was well tolerated without safety concerns with immunogenicity data supporting continued advancement. The Company anticipates adolescent data from the same trial in the fourth quarter of 2022.
• Shingles vaccine program: The Company recently completed enrollment in the ongoing Phase 1 study evaluating the safety, tolerability, and immunogenicity in adults compared to Shingrix, the leading marketed shingles vaccine in the U.S. Topline data is anticipated in the fourth quarter of 2022.
• Plague vaccine candidate: The Company anticipates that in August the first participant will be dosed in a Phase 2 clinical trial evaluating the immunogenicity, safety and tolerability of a plague vaccine candidate utilizing CpG 1018 adjuvant. The clinical trial is being conducted in collaboration with, and funded by, the U.S. Department of Defense.

SECOND-QUARTER FINANCIAL HIGHLIGHTS

Total Revenues and Product Revenue, Net.
Total revenues for the second quarter of 2022 were $256.5 million, compared to $52.8 million for the second quarter of 2021.

• U.S. HEPLISAV-B vaccine product revenue, net was $32.7 million for the second quarter of 2022, compared to $13.7 million for the second quarter of 2021. Additionally, approximately $0.9 million was reported in HEPLISAV-B net product sales associated with sales to the Company's commercialization partner in Germany, Bavarian Nordic.
• CpG 1018 adjuvant product revenue, net was $222.6 million in the second quarter of 2022 compared to $39.0 million in the second quarter of 2021.
• Selected financial highlights from CpG 1018 adjuvant product supply partnerships for COVID-19 vaccines and vaccine candidates:
• The Company recorded approximately $68.0 million in CpG 1018 adjuvant product revenue under its CSA with Valneva.  Dynavax does not have any further supply obligations under the CSA.
• The Company recorded approximately $51.0 million in CpG 1018 adjuvant product revenue under its CSA with Biological E.
• The Company recorded approximately $91.3 million in CpG 1018 adjuvant product revenue under its CSA with Clover.
• The Company recorded approximately $12.3 million in CpG 1018 adjuvant product revenue under its CSA with Bio Farma. In May 2022, Dynavax and Bio Farma entered into a CSA for the supply of CpG 1018 adjuvant to be used in Bio Farma's subunit COVID-19 vaccine candidate, currently in a Phase 3 immunogenicity and safety study.

Cost of Sales - Product. Cost of sales - product for the second quarter of 2022 increased to $83.4 million, compared to $14.8 million for the second quarter of 2021. The increase was primarily due to manufacturing costs for increased volumes of CpG 1018 adjuvant sold to COVID-19 supply partners and increased HEPLISAV-B vaccine sales volume.

Research and Development Expenses (R&D). R&D expenses for the second quarter of 2022 increased to $9.7 million, compared to $7.2 million for the second quarter of 2021. The increase was primarily driven by increased headcount-related compensation and personnel costs, including non-cash stock-based compensation, as well as investments in product candidates utilizing CpG 1018 adjuvant and additional discovery efforts.

Selling, General, and Administrative Expenses (SG&A). SG&A expenses for the second quarter of 2022 increased to $36.2 million, compared to $21.6 million for the second quarter of 2021. The increase was primarily driven by compensation and related personnel costs, including non-cash stock-based compensation, primarily associated with increased headcount as the Company expanded its field sales team to support HEPLISAV-B vaccine commercialization in mid-2021.

Interest Expense. Interest expense was $1.7 million in the second quarter of 2022, a decrease of $1.4 million from $3.1 million in the second quarter of 2021, reflecting a decreased interest rate associated with the Company's convertible senior notes due 2026.

Net Income.  GAAP net income was $128.8 million, or $1.02 per share (basic) and $0.87 per share (diluted) in the second quarter of 2022, compared to GAAP net income of $4.5 million, or $0.04 per share (basic) and $0.02 per share (diluted) in the second quarter of 2021.

Cash and Marketable Securities.  Cash and marketable securities were $518.2 million as of June 30, 2022.
