• Market share in the accounts targeted by the Dynavax field sales team increased to approximately 43%, with total market share increasing to approximately 32% in the third quarter of 2022, up from approximately 32% and 25%, respectively, in the third quarter of 2021.

CpG 1018® Adjuvant Supply for COVID-19 Vaccines

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

• CpG 1018 adjuvant revenue for the third quarter of 2022 was $126.3 million, up 50% compared to $84.3 million for the third quarter of 2021.
• The Company reiterates its expectation of 2022 full-year CpG 1018 adjuvant COVID-19 supply revenue to be between $550 million and $600 million, based on committed orders under our CSAs, 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:

• In October, the Company presented adult and adolescent safety data from the Phase 1 clinical trial demonstrating the Tdap vaccine candidate was well tolerated without safety concerns. Immunogenicity in adults was consistent with the Company's expectations and support its plan to continue advancement of this clinical program. These clinical results were presented at ID Week.

Shingles vaccine program:

• In August, enrollment was completed in the ongoing randomized Phase 1 clinical trial evaluating the safety, tolerability, and immunogenicity in adults of the Company's shingles vaccine candidate adjuvanted with CpG 1018 compared to the leading marketed shingles vaccine in the U.S.
• Data from this clinical trial is anticipated before the end of 2022.

Plague vaccine candidate:

• In August, the first participant was dosed in the Phase 2 clinical trial evaluating the immunogenicity, safety and tolerability in adults of a plague (rF1V) vaccine candidate adjuvanted with CpG 1018. The clinical trial is being conducted in collaboration with, and funded by, the U.S. Department of Defense.

THIRD-QUARTER FINANCIAL HIGHLIGHTS

• HEPLISAV-B vaccine product revenue, net was $37.5 million for the third quarter of 2022, compared to $22.7 million for the third quarter of 2021.
• CpG 1018 adjuvant product revenue, net was $126.3 million in the third quarter of 2022 compared to $84.3 million in the third quarter of 2021.

Cost of Sales - Product. Cost of sales - product for the third quarter of 2022 increased to $61.3 million, compared to $60.1 million for the third quarter of 2021. The increase was due to manufacturing costs for increased volumes of CpG 1018 adjuvant sold to COVID-19 supply partners, an inventory write-down of $14.5 million related to the reduction in demand for CpG 1018 and increased HEPLISAV-B vaccine sales volume.

Research and Development Expenses (R&D). R&D expenses for the third quarter of 2022 increased to $13.0 million, compared to $6.2 million for the third 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 for TDAP, shingles and plague.

Selling, General, and Administrative Expenses (SG&A). SG&A expenses for the third quarter of 2022 increased to $32.0 million, compared to $26.9 million for the third quarter of 2021. The increase was primarily driven by compensation and related personnel costs, including non-cash stock-based compensation coupled with increased external commercial and marketing activities related to the universal recommendation for hepatitis B vaccination.

Net Income. GAAP net income was $63.8 million, or $0.50 per share (basic) and $0.43 per share (diluted) in the third quarter of 2022, compared to GAAP net loss of $28.4 million, or $0.24 per share (basic) and $0.24 per share (diluted) in the third quarter of 2021.
