RISK FACTOR SUMMARY
Below is a summary of material factors that make an investment in our securities speculative or risky. 
Importantly, this summary does not address all of the risks and uncertainties that we face. Additional discussion of the risks 
and uncertainties summarized in this risk factor summary, as well as other risks and uncertainties that we face, can be 
found in the more detailed discussion that follows this summary, and the below summary is qualified in its entirety by that 
more complete discussion of such risks and uncertainties. You should carefully consider the risks and uncertainties 
described herein as part of your evaluation of an investment in our securities:
•
HEPLISAV-B has been approved in the United States ("U.S."), the European Union ("EU") 
and the United Kingdom and launched in the U.S. and Germany, and there is significant 
competition in these marketplaces. Since this is our first marketed product, the timing of 
uptake and distribution efforts are unpredictable and there is a risk that we may not achieve 
and sustain commercial success for HEPLISAV-B.
•
Our financial results may vary significantly from quarter to quarter or may fall below the 
expectations of investors or securities analysts, each of which may adversely affect our 
stock price.
•
We have incurred annual net losses in most years since our inception and could continue to 
incur significant losses if we do not successfully commercialize HEPLISAV-B, launch new 
products and/or significant sales of our CpG 1018 adjuvant do not resume. Until we are 
able to generate significant revenues or achieve profitability through product sales on a 
consistent basis, we may require substantial additional capital to finance our operations. 
•
Many of our competitors have greater financial resources and expertise than we do. If we 
are unable to successfully compete with existing or potential competitors as a result of these 
disadvantages, we may be unable to generate sufficient, or any, revenues and our business 
will be harmed.
•
We rely on our facility in Düsseldorf, Germany and third parties to supply materials or 
perform processes necessary to manufacture our products and our product candidates. We 
rely on a limited number of suppliers to produce the oligonucleotides we require for 
development and commercialization. Additionally, we have limited experience in 
manufacturing our products or product candidates in commercial quantities. With respect to 
HEPLISAV-B, we use a pre-filled syringe presentation of the vaccine and our ability to 
meet future demand will depend on our ability to manufacture or have manufactured 
sufficient supply in this presentation.
•
As we continue to focus on the commercialization of our HEPLISAV-B vaccine and our 
CpG 1018 adjuvant, we may encounter difficulties in managing our commercial growth and 
expanding our operations successfully.
•
As we continue to grow as a commercial organization and enter into supply agreements 
with customers, those supply agreements will have obligations to deliver product that we 
are in part reliant upon third parties to manufacture on our behalf. 
•
We face uncertainty regarding coverage, pricing and reimbursement and the practices of 
third-party payors, which may make it difficult or impossible to sell certain of our products 
or product candidates on commercially reasonable terms.
•
We are subject to ongoing U.S. Food and Drug Administration (“FDA”), EU and 
comparable foreign post-marketing obligations concerning HEPLISAV-B, which may 
result in significant additional expense, and we may be subject to penalties if we fail to 
comply with regulatory requirements or experience unanticipated regulatory issues with 
HEPLISAV-B. If HEPLISAV-B or any products we develop are not accepted by the market 
or if regulatory authorities limit our labeling indications, require labeling content that 
diminishes market uptake of HEPLISAV-B or any other products we develop, or limit our 
marketing claims, we may be unable to generate significant future revenues, if any.
•
HEPLISAV-B and all of our clinical programs rely on oligonucleotide toll-like receptor 
(“TLR”) agonists. In the event of serious adverse events relating to TLR agonists, we may 
be required to reduce the scope of, or discontinue, our operations, or reevaluate the viability 
of strategic alternatives.
4

•
HEPLISAV-B is subject to regulatory obligations and continued regulatory review, and if 
we receive regulatory approval for our other product candidates, we will be subject to 
ongoing FDA and foreign regulatory obligations and continued regulatory review for such 
products.
•
Regulatory authorities may require more clinical trials for our product candidates than we 
currently expect or are conducting before granting regulatory approval, if regulatory 
approval is granted at all. Our clinical trials may be extended which may lead to substantial 
delays in the regulatory approval process for our product candidates and may impair our 
ability to generate revenues.
•
Clinical trials for our commercial product and product candidates are expensive and time 
consuming, may take longer than we expect or may not be completed at all, and have 
uncertain outcomes.
•
A key part of our business strategy for products in development is to establish collaborative 
relationships to help fund or manage development and commercialization of our product 
candidates and research programs. We may not succeed in establishing and maintaining 
collaborative relationships, which may significantly limit our ability to continue to develop 
and commercialize those products and programs, if at all. 
•
As we plan for the broader commercialization of our HEPLISAV-B vaccine and for the 
requisite capacity to manufacture our CpG 1018 adjuvant, our financial commitments for 
manufacturing and supply capacity might outpace actual demand for our products.
•
We may develop, seek regulatory approval for and market HEPLISAV-B or any other 
product candidates outside of the U.S., the European Union and the United Kingdom, 
requiring a significant additional commitment of resources. Failure to successfully manage 
our international operations could result in significant unanticipated costs and delays in 
regulatory approval or commercialization of our products or product candidates.
•
We rely on clinical research organizations (“CROs”) and clinical sites and investigators for 
our clinical trials. If these third parties do not fulfill their contractual obligations or meet 
expected deadlines, our planned clinical trials may be delayed and we may fail to obtain the 
regulatory approvals necessary to commercialize our product candidates.
•
As a biopharmaceutical company, we engage CROs to conduct clinical studies, and failure 
by us or our CROs to conduct a clinical study in accordance with good clinical practices 
(“GCP”) standards and other applicable regulatory requirements could result in 
disqualification of the applicable clinical trial from consideration in support of approval of a 
potential product.
•
If third parties assert that we have infringed their patents or other proprietary rights or 
challenge our patents or other proprietary rights, we may become involved in disputes and 
litigation that would be costly, time consuming and have a negative impact on the 
commercialization of our current products and delay or prevent development or 
commercialization of our product candidates.
•
Our stock price is subject to volatility, and your investment may suffer a decline in value. 
•
Future sales of our common stock or the perception that such sales may occur in the public 
market could cause our stock price to fall.
•
Servicing our Convertible Notes (defined below) requires a significant amount of cash, and 
we may not have sufficient cash flow from our business to pay our substantial debt. 
Conversion of the Convertible Notes may dilute the ownership interest of our stockholders 
or may otherwise depress the price of our common stock.
•
The loss of key personnel could delay or prevent achieving our objectives. In addition, our 
continued growth to support commercialization may result in difficulties in managing our 
growth and expanding our operations successfully.
•
If our information technology systems or those of third parties upon which we rely, or our 
data are or were compromised, we could experience adverse consequences resulting from 
such compromise, including but not limited to regulatory investigations or actions; 
litigation; fines and penalties; disruptions of our business operations; reputational harm; 
loss of revenue or profits; and other adverse consequences.

PART I
ITEM 1. BUSINESS
OUR COMPANY
We are a commercial stage biopharmaceutical company developing and commercializing innovative 
vaccines to help protect the world against infectious diseases. We are currently focused on our efforts to drive long-term 
shareholder value by maximizing utilization of our HEPLISAV-B® hepatitis B vaccine, expanding our own portfolio of 
innovative vaccine candidates leveraging our proven CpG 1018® adjuvant technology, and identifying strategic 
opportunities to accelerate growth through both commercial and research collaborations.
HEPLISAV-B [Hepatitis B Vaccine (Recombinant), Adjuvanted]
Our first marketed product, HEPLISAV-B [Hepatitis B Vaccine (Recombinant), Adjuvanted], is approved 
in the United States ("U.S."), the European Union ("EU") and the United Kingdom for prevention of infection caused by all 
known subtypes of hepatitis B virus ("HBV") in adults aged 18 years and older. HEPLISAV-B is the only two-dose 
hepatitis B vaccine for adults approved in the U.S., EU and the United Kingdom. In Phase 3 trials, HEPLISAV-B 
demonstrated faster and higher rates of protection with two doses in one month compared to other currently approved 
hepatitis B vaccines, which require three doses over six months, with similar safety profiles. We received marketing 
authorization approval of HEPLISAV-B in February 2021 from the European Commission for prevention of infection 
caused by all known subtypes of HBV in adults aged 18 years and older. In May 2021, we entered into a commercialization 
agreement with Bavarian Nordic for the marketing and distribution of HEPLISAV-B in Germany, and in May 2022, we 
commenced commercial shipments of HEPLISAV-B in Germany. In March 2023, we received marketing authorization in 
the United Kingdom for HEPLISAV-B for the active immunization against hepatitis B virus infection caused by all known 
subtypes of hepatitis B virus in adults aged 18 years and older.
Pipeline Programs
We are advancing a pipeline of differentiated product candidates that leverage our CpG 1018 adjuvant to 
develop improved vaccines in indications with unmet medical needs. These programs include vaccine candidates under 
development for shingles and plague and additional vaccine programs in preclinical development.
•
Shingles vaccine program: Z-1018 is an investigational vaccine candidate being developed 
for the prevention of shingles in adults aged 50 and older. 
•
Plague vaccine program: We are developing a plague (rF1V) vaccine candidate adjuvanted 
with CpG 1018 in collaboration with and fully funded by the U.S. Department of Defense 
("DoD").
Additionally, we manufacture and have supplied in the past CpG 1018 adjuvant, the adjuvant used in 
HEPLISAV-B, through both commercial supply agreements and preclinical and clinical research collaborations with third-
party organizations.
Adjuvant Technology Overview: Toll-like Receptor Targeted Immune Modulation Platform
Toll-like receptors (TLRs) are a family of transmembrane proteins that play a vital role in innate immunity 
and subsequent adaptive immunity. Signaling through these receptors is triggered by the binding of a variety of pathogen-
associated molecules and is essential to generation of innate immunity. The innate immune response is the first line of 
defense against viruses, bacteria and other potential pathogens. Importantly, the innate response initiates and regulates the 
generation of an adaptive immune response composed of highly specific antibodies and T cells. Compounds used in 
vaccine products that stimulate enhanced immune responses are generally referred to as adjuvants.
Our work in this area has been focused primarily on stimulation of a subset of TLRs that recognize 
bacterial and viral nucleic acids. This work resulted in the identification of proprietary unmethylated synthetic 
oligonucleotides (short segments of deoxyribonucleic acid (DNA)), that mimic the activity of microbial DNA, and 
selectively activate one of these important receptors, TLR9. These TLR9 agonists are called CpG oligonucleotides – or 
“CpGs” for short – referring to the presence of specific nucleotide sequences containing the CG base pair. 
Our vaccine research to date has focused on the use of TLR9 agonists as novel vaccine adjuvants. B-Class 
TLR9 agonists, such as our CpG 1018 adjuvant, stimulate release of cytokines necessary for T cell activation establishing 
long-term immunity. TLR9 stimulation particularly helps generate Th1 immune responses that are important to control 
pathogens such as viruses and bacteria. As a result, TLR9 adjuvanted vaccines induce a specific Th1 immune response and 
6

more durable levels of protective antibodies relative to non-adjuvanted vaccines. Our CpG 1018 adjuvant has an 
established tolerability profile demonstrated in a wide range of clinical trials and real-world, commercial use, and has 
consistently demonstrated its ability to enhance the immune response without excessive reactogenicity as shown in 
multiple clinical trials in our HEPLISAV-B and COVID-19 vaccine collaboration programs. 
Key 2024 Business and Financial Highlights
Drive Growth of HEPLISAV-B [Hepatitis B Vaccine (Recombinant), Adjuvanted] 
HEPLISAV-B vaccine is the first and only adult hepatitis B vaccine approved in the U.S. and EU that enables series 
completion with only two doses in one month. Hepatitis B vaccination is universally recommended for adults aged 19-59 in 
the U.S.
•
We recognized $268.4 million of HEPLISAV-B product revenue during the year ended 
December 31, 2024, representing a 26% increase compared to the year ended December 31, 
2023. This increase was primarily driven by an increase in the adult hepatitis B vaccine 
market and HEPLISAV-B market share gains in the U.S. in 2024, compared to 2023.
•
HEPLISAV-B estimated total market share in the U.S. increased to approximately 44% at 
the end of 2024, compared to approximately 42% at the end of 2023.
•
We continue to expect the hepatitis B adult vaccine market in the U.S. to expand to a peak 
of over $900.0 million in annual sales by 2030, with HEPLISAV-B expected to achieve at 
least 60% total market share. Additionally, we believe the HEPLISAV-B U.S. market 
opportunity will remain substantial beyond 2030 due to the ongoing penetration of the 
unvaccinated eligible adult population, observed revaccination practices by healthcare 
providers, and continued gains in market share. 
•
We generated $66.5 million in cash from operating activities during the year ended 
December 31, 2024 and ended the year with $713.8 million in cash and cash equivalents 
and marketable securities.
•
We reported a net income of $27.3 million during the year ended December 31, 2024.
Advance Clinical Pipeline Leveraging our Proven Adjuvant Technology
We are advancing a pipeline of product candidates that leverage our 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.
Shingles vaccine program:
Z-1018 is an investigational vaccine candidate being developed for the prevention of shingles in adults aged 50 years and 
older.
•
We are currently conducting a randomized, active-controlled, dose escalation, multicenter 
Phase 1/2 trial to evaluate the safety, tolerability, and immunogenicity of Z-1018 compared 
to Shingrix® in 441 healthy adults aged 50 to 69.
•
In the fourth quarter of 2024, we completed enrollment in the trial, and we anticipate 
reporting top line immunogenicity and safety data in the third quarter of 2025.
Plague vaccine candidate:
We are developing a plague (rF1V) vaccine candidate adjuvanted with CpG 1018® in collaboration with, and fully funded 
by, the U.S. Department of Defense ("DoD").
•
Based on the results from a randomized, active-controlled Phase 2 clinical trial of the two-
dose plague vaccine adjuvanted with CpG 1018, we and the DoD executed a new 
agreement for approximately $30.0 million through the first half of 2027 to support 
additional clinical and manufacturing activities, including a Phase 2 clinical trial expected 
to initiate in the third quarter of 2025.
7

HEPLISAV-B for Adults on Hemodialysis:
We are developing a four-dose HEPLISAV-B vaccine regimen for adults on hemodialysis.
•
In the fourth quarter of 2024, we received feedback from the FDA regarding the potential to 
conduct an observational retrospective cohort study to support our sBLA filing for adults on 
hemodialysis.
Tdap vaccine program: 
•
In November 2024, we announced that we have decided to discontinue development of our 
Tdap-1018 program based on results from a long-term Phase 1 extension study that did not 
demonstrate a differentiated profile that we believe would be successful commercially.
OUR STRATEGY
Our vision is to continue building a leading vaccines company dedicated to developing and 
commercializing innovative vaccines to help protect the world against infectious diseases. Our strategy is focused on our 
core priorities: drive growth in our HEPLISAV-B commercial vaccine, advance a differentiated vaccine pipeline, and 
identify strategic opportunities to accelerate growth. Key elements of our strategy include: 
•
Increase our HEPLISAV-B vaccine market share to become the market leader in the future;
•
Maximize total addressable HEPLISAV-B vaccine market based on the CDC's Advisory 
Committee on Immunization Practices ("ACIP") Universal Recommendation;
•
Leverage HEPLISAV-B vaccine as a foundational commercial asset to support company 
growth and pipeline development;
•
Deliver on our innovative and diversified pipeline leveraging CpG 1018 adjuvant with 
proven antigens;
•
Build an adult vaccine portfolio of best-in-class products;
•
Advance innovative pre-clinical and discovery efforts leveraging collaborations;
•
Continue disciplined allocation of capital aligned with corporate strategy to deliver long-
term value through internal and external innovation; and
•
Pursue external opportunities with high synergy assets in vaccines, or other modalities in 
infectious diseases, to further leverage our expertise and capabilities. 
HEPLISAV-B [Hepatitis B Vaccine, (Recombinant), Adjuvanted]
Our first commercial product, HEPLISAV-B [Hepatitis B Vaccine, (Recombinant), Adjuvanted], is 
approved by the FDA, the European Commission and the UK Medicines and Healthcare products Regulatory Agency for 
prevention of infection caused by all known subtypes of HBV in adults aged 18 years and older. HEPLISAV-B combines 
CpG 1018 adjuvant, our proprietary TLR9 agonist adjuvant, and recombinant hepatitis B surface antigen (“rHBsAg” or 
“HBsAg”) that is manufactured by Dynavax GmbH, our wholly owned subsidiary, in Düsseldorf, Germany. HEPLISAV-B 
and each of the vaccines it directly competes against use rHBsAg to elicit an immune response to the virus. 
About Hepatitis B
Hepatitis B is a potentially life-threatening liver infection caused by HBV. It is a major global health 
problem. It can cause chronic infection and puts people at high risk of death from cirrhosis and liver cancer. The World 
Health Organization (“WHO”) and the CDC have set a goal to eliminate all viral hepatitis infections, including hepatitis B, 
globally by 2030, and are calling for a continued commitment to increase services to eliminate hepatitis. The WHO 
estimates that worldwide, approximately 254.0 million people were living with chronic hepatitis B in 2022, and that in the 
same year hepatitis B resulted in an estimated 1.1 million deaths primarily from liver cancer. In addition, the CDC 
estimated that in 2021 approximately 580,000 to 1.2 million people in the U.S. were living with HBV infection. There was 
a total of 2,045 new cases of acute hepatitis B reported to the CDC in 2021. However, after adjusting for under-
ascertainment and under-reporting, the CDC estimated that 14,229 acute hepatitis B cases occurred in the U.S. in 2021.
8

Recommendations for Adult Vaccination to Prevent Hepatitis B 
The CDC’s ACIP unanimously voted at its November 2021 meeting to recommend that all adults 19 to 59 
years of age should receive a hepatitis B vaccination, and such recommendation was published in April 2022. This 
universal recommendation greatly simplifies the identification of patients who need a hepatitis B vaccine compared to the 
previous risk-based recommendation, and significantly expands the number of adults in the U.S. who should be vaccinated 
against hepatitis B under the CDC recommendation. Based on this opportunity, we launched a series of innovative 
marketing campaigns targeting consumers and healthcare providers to increase the awareness of HEPLISAV-B as the only 
two-dose hepatitis B vaccine option, with broad protection across most patient types. Such efforts have driven an increase 
in HEPLISAV-B demand and market share in the U.S. in 2024 compared to 2023.
Protection Against Hepatitis B by HEPLISAV-B
The approval of HEPLISAV-B by the FDA was based on data from three Phase 3 non-inferiority trials 
involving nearly 10,000 adult participants who received HEPLISAV-B. These pivotal studies compared HEPLISAV-B 
administered in two doses over one month to Engerix-B® administered in three doses over a six-month schedule. Results 
from HBV-23, the largest Phase 3 trial, which included 6,665 participants, showed that HEPLISAV-B demonstrated a 
statistically significantly higher rate of protection of 95% compared with 81% for Engerix-B. Across the three clinical 
trials, the most common local reaction was injection site pain (23% to 39%). The most common systemic reactions were 
fatigue (11% to 17%) and headache (8% to 17%). 
We have worldwide commercial rights to HEPLISAV-B. In addition to HEPLISAV-B, there are four other 
vaccines approved for the prevention of hepatitis B in the U.S.: Engerix-B and Twinrix® from GlaxoSmithKline plc 
(GSK), Recombivax-HB® from Merck & Co. (“Merck”) and PreHevbrio™ from VBI Vaccines Inc. HEPLISAV-B is 
currently approved in the U.S., the EU and the United Kingdom for the prevention of hepatitis B in adults. We are also 
considering additional territories where it would be commercially feasible to market HEPLISAV-B. 
The largest segments of the market are concentrated in independent hospitals and clinics, integrated 
delivery networks, dialysis centers, public health clinics and prisons, the Departments of Defense and Veterans Affairs and 
retail pharmacies. Our promotional activity is focused on the largest accounts in each segment. Our field sales force of 
approximately 103 people are targeting customers that we believe have the highest impact on adult hepatitis B vaccine 
utilization in the U.S. We deploy our sales force to the physician or pharmacist level, as well as at the procurement level 
within respective healthcare segments where vaccines are utilized. Our primary objectives are to both increase market share 
and increase market size over time.
We continue to explore ways to enhance the clinical profile of HEPLISAV-B. We completed an open-label, 
single-arm study of a 4-dose regimen of HEPLISAV-B in adults with end-stage renal disease who are initiating or 
undergoing hemodialysis. Final immunogenicity results included a seroprotection rate of 89.3% with high levels of anti-
HBs antibodies. Safety data showed HEPLISAV-B was well tolerated and no safety concerns were observed. The safety 
and effectiveness of HEPLISAV-B in adults on hemodialysis have not yet been established. If we do receive approval of 
this dosing schedule, we expect to add dialysis centers to our personal promotion efforts. We submitted an sBLA for 
HEPLISAV-B vaccination of adults on hemodialysis to the FDA and received a Complete Response Letter ("CRL") in 
May 2024 that stated the data were insufficient to support the immunogenicity and safety of the four-dose regimen.We are 
exploring approaches to address the deficiencies identified in the CRL. In the fourth quarter of 2024, we received feedback 
from the FDA regarding the potential to conduct an observational retrospective cohort study to support our sBLA filing for 
adults on hemodialysis. We expect to resubmit our sBLA for HEPLISAV-B vaccination of adults on hemodialysis to the 
FDA in 2025.
CpG 1018 Vaccine Adjuvant
We believe the favorable immunogenicity and safety results achieved with HEPLISAV-B utilizing our CpG 
1018 adjuvant support our efforts to develop it as a broadly useful vaccine adjuvant platform. CpG 1018 adjuvant has an 
established profile for the potential development of safe and effective vaccines. It has a well-defined mechanism of action, 
targeting select immune system cells, with well-characterized effects on the immune response that mimic the immune 
response to naturally occurring TLR9 agonists in pathogens. This results in potent adjuvant activity for antibody responses. 
In HEPLISAV-B, our CpG 1018 adjuvant is believed to drive faster and consistently higher rates of seroprotection than 
Engerix-B, even in the elderly and populations known to be less responsive to other vaccines. CpG 1018 adjuvant 
differentially elicits a preferred T Helper 1 (Th1) cell polarized response and drives protective antibody production. CpG 
1018 adjuvant has a large safety database that indicates a favorable safety profile with lower reactogenicity compared to 
other adjuvants. We have established several clinical and preclinical collaborations with vaccine developers to evaluate 
9

CpG 1018 adjuvanted vaccine product candidates against influenza, other infectious diseases, and particularly COVID-19 
across a variety of vaccine platforms. 
Our Vaccine Research and Development Pipeline
We are building an innovative pipeline of investigational vaccine product candidates, leveraging our 
proven, proprietary vaccine adjuvant technology. A summary of our pipeline programs follows:
Shingles Vaccine Program
Shingles is an extremely painful consequence of the reactivation of a latent varicella-zoster virus (“VZV”) 
infection, with attacks leading to potential complications including chronic pain. The global shingles vaccine market was 
over $4.0 billion in 2024. Our CpG 1018 adjuvant has demonstrated its ability to enhance the immune response without 
excessive reactogenicity in both HEPLISAV-B and multiple COVID-19 clinical trials. Importantly, CpG 1018 adjuvant has 
shown the ability to generate high levels of CD4+ T-cell which have been demonstrated to be key cell types in controlling 
latent VZV infection to avoid reactivation leading to shingles, with potentially lower reactogenicity compared to the 
current standard of care.
In January 2022, we initiated a Phase 1 clinical trial of our shingles vaccine candidate, utilizing our CpG 
1018 adjuvant. The Phase 1 study was designed to evaluate safety, tolerability and immunogenicity of the vaccine 
candidate which is comprised of glycoprotein E (gE) plus CpG 1018 adjuvant.
In January 2023, we announced the completion of a randomized Phase 1 clinical trial of our shingles 
vaccine program evaluating the safety, tolerability, and immunogenicity in adults. At four weeks following the 2-dose 
regimen, the investigational shingles vaccine Z-1018 demonstrated high antibody and CD4+ T-cell vaccine response rates 
in all arms, which were similar to the licensed comparator. Robust increases in CD4+ T-cells were observed in all Z-1018 
arms, although lower than the comparator. Total frequency of solicited systemic adverse events and local post-injection 
reactions and moderate and severe reactions were similar across the Z-1018 arms and lower than the comparator. 
In June 2023, we presented results from the Phase 1 trial at the National Foundation for Infectious 
Diseases’ 2023 Annual Conference on Vaccinology Research. These results demonstrate the opportunity to develop a 
shingles vaccine with improved vaccine tolerability and comparable efficacy to Shingrix and support the continued 
development of our shingles vaccine candidate. We received Type B meeting feedback from the FDA on the Z-1018 
clinical development plan and submitted an IND to the FDA to support the initiation of a Phase 1/2 trial of Z-1018, upon 
IND clearance, in the first half of 2024. 
In June 2024, we initiated a Phase 1/2 clinical trial evaluating the safety, tolerability, and immunogenicity 
of Z-1018. Enrollment in the Phase 1/2 randomized, active-controlled, dose escalation, multicenter trial was completed in 
2024, with approximately 440 healthy adults aged 50 to 69 years enrolled at trial sites in Australia. The trial will evaluate 
the safety, tolerability, and immunogenicity of Z-1018 compared to Shingrix. Key objectives of the trial include selecting 
the optimal glycoprotein E (gE) protein dose level and dosing schedule for further clinical development. The Phase 1/2 trial 
will be used to support validation of a Patient Reported Outcome measurement tool to differentiate Z-1018 on tolerability 
and to support potential label claims. We anticipate reporting top line immunogenicity and safety data in the third quarter 
of 2025.
Tdap Vaccine Program
In June 2017, we entered into an agreement with Serum Institute of India Pvt. Ltd. ("SIIPL") to collaborate 
on development and commercialization of certain potential vaccines including Tdap booster adjuvated with CpG 1018. 
Under the collaboration, we have exclusive worldwide rights to commercialize the vaccine, except that SIIPL has exclusive 
rights to distribute in India and to fulfill WHO/United Nations Children's Fund (UNICEF) tender contracts. Each party is 
responsible for clinical development cost in their respective territories.
In October 2022, we presented adult and adolescent safety data from the Phase 1 clinical trial of 
Tdap-1018, which was well tolerated with no safety concerns observed. Additionally, immunogenicity levels in adults met 
our expectations and support our plan to continue advancement of this clinical program. 
In December 2023, we completed a pertussis challenge study in nonhuman primates demonstrating 
protection from disease upon challenge and robust Type 1 T helper (Th1) cell responses in nonhuman primates vaccinated 
with Tdap-1018. After we received Type B meeting feedback from the FDA on the Tdap-1018 clinical development plan, 
10

we evaluated the persistence of pertussis immunogenicity of Tdap-1018 through a long-term follow-up study of 
participants that completed a Phase 1 trial of a booster dose of Tdap-1018 compared to an active control. Based on results 
from this long-term follow-up study, in November 2024 we decided to discontinue development of the Tdap-1018 program 
as it did not demonstrate a differentiated profile that we believe would be successful commercially.
U.S. Department of Defense (Plague Vaccine) Phase 2 Program
In September 2021, we entered into an agreement with the U.S. Department of Defense ("DoD") for the 
development of a recombinant plague vaccine adjuvanted with CpG 1018 for approximately $22.0 million over two and a 
half years. Under the agreement, we agreed to conduct a Phase 2 clinical trial combining our CpG 1018 adjuvant with the 
DoD's rF1V vaccine designed to show that two doses of CpG 1018 adjuvanted vaccine administrated within a period of one 
month is similar to three doses of the aluminum-adjuvanted vaccine administered over a period of six months.
In August 2022, we commenced the Phase 2 clinical trial with the first participant dosed, evaluating the 
immunogenicity, safety and tolerability of the DoD’s rF1V vaccine combined with our CpG 1018 adjuvant, in adults 18 to 
55 years of age. 
In January 2023, Part 1 of the Phase 2 clinical trial evaluating the immunogenicity, safety, and tolerability 
in adults of a plague (rF1V) vaccine candidate adjuvanted with CpG 1018 was successfully completed. Both CpG 1018 
adjuvanted arms met the Part 1 primary endpoint and demonstrated a greater than two-fold increase in antibodies over the 
alum adjuvanted control arm after two doses. In 2023, we completed enrollment and dosing in Part 2 of the Phase 2 clinical 
trial evaluating immunogenicity, safety, and tolerability. Preliminary results were received in 2024.
In July 2023, we executed a contract modification with the DoD to support advancement of the plague 
vaccine candidate into a nonhuman primate challenge study. This study was completed in 2024 and totaled $33.7 million.
In late 2024, we completed the phase 2 clinical trial evaluating the immunogenicity, safety, and tolerability 
in adults of a plague (rF1V) vaccine candidate adjuvanted with CpG 1018. Based on the results from that study, we 
executed a new agreement with the DoD for approximately $30.0 million through the first half of 2027 to support 
additional Phase 2 clinical and manufacturing activities.
CpG 1018 Adjuvant Supply Partnerships for COVID-19 Vaccine Development
To support the fight against COVID-19, we collaborated with five other organizations on their development 
of COVID-19 vaccines, by supplying them with CpG 1018 adjuvant under commercial supply agreements supported by 
two contract manufacturing organizations, with whom we developed and implemented plans to help scale-up activities to 
support pandemic-level production of our CpG 1018 adjuvant as necessary to support these and any future collaborations. 
As of December 31, 2022, our delivery obligations under our related supply agreements with all five organizations had 
been fully satisfied. Under our agreement (together with subsequent amendments, the "CEPI Agreement") with Coalition 
for Epidemic Preparedness Innovations (“CEPI”), through December 31, 2024, we received advance payments totaling 
approximately $175.0 million, of which $67.3 million have been repaid and $47.4 million have been forgiven. As of 
December 31, 2024 and 2023, remaining advance payments totaling $60.3 million in CEPI accrual long-term were 
reflected in our consolidated balance sheets. We continue to work to identify other programs where CpG 1018 adjuvant can 
be utilized to enhance the immune response to a coronavirus vaccine or other vaccines. 
For a summary of our significant CpG 1018 adjuvant collaboration agreements, see Note 9 - Collaborative 
Research, Development and License Agreements, in the accompanying notes to the consolidated financial statements 
included in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K.
INTELLECTUAL PROPERTY
Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our 
products, product candidates, technology and know-how, to operate without infringing the proprietary rights of others and 
to prevent others from infringing our proprietary rights. Generally, we seek patent protection in the U.S and foreign 
countries on a selective basis to further protect the inventions that we or our partners consider important to the development 
of our business. We also rely on trade secrets and contracts to protect our proprietary information, and we rely on 
trademarks to protect our brand, products, product candidates, and technology.
As of December 31, 2024, our intellectual property portfolio included over 20 issued U.S. patents, over 45 
granted foreign patents and over 130 additional Dynavax-solely owned or co-owned pending U.S. non-provisional and 
11

foreign patent applications claiming compositions containing TLR agonists or antagonists, methods of use, and/or methods 
of manufacture thereof. Specifically, our portfolio includes: (i) three issued U.S. patents related to certain uses of 
HEPLISAV-B that expire in 2032; (ii) 32 pending U.S. and foreign patent applications related to an investigational 
shingles vaccine; (iii) four issued U.S. and foreign patents and 53 pending U.S. non-provisional and foreign patent 
applications related to COVID-19 vaccines, which include patent families that are either solely-owned or co-owned with 
Valneva Austria GmbH, Medigen Vaccine Biologics Corporation, or Colorado State University Research Foundation; and 
(iv) one pending U.S. patent application related to an investigational plague vaccine, which is co-owned with The 
Government of the United States, as Represented by the Secretary of the Army. Lastly, some of the patents and patent 
applications in our portfolio relate to our discontinued tetanus, diphtheria, pertussis (Tdap) booster vaccine and immuno-
oncology programs.
In general, the term of a patent extends for 20 years from the filing date of the earliest U.S. non-provisional 
or international (PCT) application to which priority is claimed. In certain instances, a patent term may be extended to 
recapture a portion of the term effectively lost as a result of the FDA regulatory review period. Moreover, in the U.S., the 
term of a patent may be extended as a consequence of patent office delays during prosecution. Our patent estate, based on 
patents existing now and expected by us to issue based on pending applications, is projected to expire on dates ranging 
from 2025 to 2044.
The actual protection afforded by a patent varies on a product-by-product basis, from country-to-country 
and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory related 
extensions, the availability of legal remedies in a particular country and the validity and enforceability of the patents. 
Because patent applications in the U.S. and many foreign jurisdictions typically are not published until 18 
months after filing and publications of discoveries in the scientific literature often lag behind actual discoveries, we cannot 
be certain that we were the first to file for protection of the inventions set forth in these patent applications or in our issued 
patents. Further, there could be post-grant proceedings such as inter partes review (IPR), post grant review (PGR), 
reexamination, reissue or opposition which could result in claims in our patents being narrowed or invalidated. 
Our commercial success depends significantly on our ability to operate without infringing patents and other 
proprietary rights of third parties. A number of pharmaceutical companies and biotechnology companies, as well as 
universities and research institutions, may have filed patent applications or may have been granted patents that cover 
inventions similar to the inventions owned by or licensed to us. We may not be able to determine with certainty whether 
patents or patent applications of other parties may materially affect our ability to make, use, offer to sell, or sell any 
products. If another party controls patents or patent applications covering our products, we may not be able to obtain the 
rights we need to those patents or patent applications in order to commercialize our products. 
Litigation may be necessary to enforce patents issued or licensed to us or to determine the scope or validity 
of another party’s proprietary rights. The existence of third-party patent applications and patents could significantly reduce 
the coverage of the patents owned by or licensed to us and limit our ability to obtain meaningful patent protection. 
Litigation or any other proceedings could result in substantial costs to and diversion of effort by us, and an adverse 
outcome in a court or patent office could subject us to significant liabilities, require disputed rights to be licensed from 
other parties, or require us to cease using some of our technology. We may not prevail in these actions or proceedings if 
they arise. 
In addition, other parties may duplicate, design around or independently develop similar or alternative 
technologies to ours or our licensors. 
We may rely, in some circumstances, on trade secrets and confidentiality agreements to protect our 
technology. Although trade secrets are difficult to protect, wherever possible, we use confidential disclosure agreements to 
protect the proprietary nature of our technology. Our standard practice is to require each of our collaborators, commercial 
partners, employees, consultants, contractors and advisors to enter into an agreement before beginning their employment, 
consulting or advisory relationship with us that in general provides that the individuals must keep confidential and not 
disclose to other parties any of our confidential information developed or learned by the individuals during the course of 
their relationship with us except in limited circumstances. These agreements with employees, consultants and contractors 
also generally provide that we own all inventions conceived by the individuals in the course of rendering their employment 
or services to us. However, there can be no assurance that these agreements will not be breached, that we will have 
adequate remedies for any breach, or that our trade secrets and/or proprietary information will not otherwise become 
known or be independently discovered by competitors. To the extent that our employees, consultants or contractors use 
intellectual property owned by others in their work for us, disputes may also arise as to the rights in related or resulting 
know-how and inventions. 
12

COMPETITION
The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, 
intense competition and a strong emphasis on proprietary products. Our products and development programs compete with 
several commercially available vaccine and adjuvant products. Many companies and institutions are making substantial 
investments in developing additional vaccines and adjuvants that could compete directly or indirectly with our marketed 
products and products under development by us and our collaborators. For example, there are multiple other shingles 
vaccine candidates in development including those being developed by Pfizer, BioNTech SE, Curevo Vaccine, Moderna, 
Inc., and others. The approved products from these programs will all need to compete with a single approved vaccine 
currently available in the U.S. 
We also believe our CpG 1018 adjuvant, which we use in our own products and product candidates and 
provide to our collaborators through clinical and commercial supply agreements, is as or more effective than other 
available adjuvants and, being a yeast-derived product, is far more sustainable that other available products that are derived 
from, for example, shark squalene or tree bark. Regardless, there can be no guarantee that we can compete with other 
companies for sales of adjuvant, or any approved vaccine.
Competition for HEPLISAV-B
HEPLISAV-B, a two-dose in one month adult hepatitis B vaccine, competes directly with three-dose over 
six months marketed vaccines Engerix-B from GSK, as well as Recombivax-HB marketed by Merck. There are also 
modified schedules of conventional hepatitis B vaccines for limited age ranges that are approved in the EU, the United 
Kingdom and the U.S. In addition, HEPLISAV-B competes against Twinrix, a bivalent vaccine marketed by GSK for 
protection against hepatitis B and hepatitis A, and PreHevbrio, a three-dose adult hepatitis B vaccine manufactured by VBI 
Vaccines Inc. (“VBI”). While we believe that HEPLISAV-B competes very well with other approved vaccines available on 
the market, we face significant competition in our longer term goal to capture a majority of U.S. market share. To the 
extent that we explore additional territories outside of the U.S., the EU and the United Kingdom to market HEPLISAV-B, 
in doing so we will likely face competition from these or other products and competitors.
Competition for our adjuvant supply supporting COVID-19 and our development pipeline including shingles, plague and 
other potential pipeline indications 
We are also in competition with companies developing vaccines, and vaccine adjuvants, generally 
including, among others, GSK, Pfizer, Inc., Sanofi S.A., Merck, Bavarian Nordic A/S, Emergent BioSolutions, Inc., 
Novavax, Inc., Medicago Inc., Valneva, AstraZeneca plc, Moderna, Inc., and Johnson & Johnson. 
Many of the entities developing or marketing these competing products have significantly greater financial 
resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, 
obtaining regulatory approvals and marketing than we do. Smaller or early-stage companies may also prove to be 
significant competitors, particularly through collaborative agreements with large, established companies with access to 
capital. These entities may also compete with us in recruiting and retaining qualified scientific and management personnel, 
as well as in acquiring technologies complementary to or necessary for our programs. 
REGULATORY CONSIDERATIONS 
Government Regulation
The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries 
impose extensive requirements upon the clinical development, pre-market approval, manufacture, labeling, marketing, 
promotion, pricing, import, export, storage and distribution of biopharmaceuticals. These agencies and other regulatory 
agencies regulate research and development activities and the testing, approval, manufacture, quality control, safety, 
effectiveness, labeling, storage, recordkeeping, advertising and promotion of drugs and biologics. Failure to comply with 
applicable FDA or foreign regulatory agency requirements may result in warning letters, fines, civil or criminal penalties, 
additional reporting obligations and/or agency oversight, suspension or delays in clinical development, recall or seizure of 
products, partial or total suspension of production or withdrawal of a product from the market. 
In the U.S., the FDA regulates drug products under the Federal Food, Drug, and Cosmetic Act and its 
implementing regulations and biologics additionally under the Public Health Service Act. The process required by the FDA 
before biopharmaceuticals may be marketed in the U.S. generally involves the following: 
•
submission to the FDA of an IND, which must become effective before human clinical 
trials may begin and, at a minimum, must be updated annually; 
13

•
completion of extensive pre-clinical laboratory tests and pre-clinical animal studies, all 
performed in accordance with the FDA’s Good Laboratory Practice (“GLP”) regulations; 
•
performance of adequate and well controlled human clinical trials to establish the safety and 
efficacy of the product for each proposed indication; 
•
submission to the FDA of a new drug application ("NDA") or a biologics license 
application ("BLA") depending on the nature of the product after completion of all pivotal 
clinical trials to demonstrate the safety, purity and potency of the product for the indication 
for use; 
•
a determination by the FDA to accept the application for review; 
•
satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities 
to assess compliance with the FDA’s current good manufacturing practices (“cGMP”) 
regulations for pharmaceuticals; and 
•
FDA review and approval of an NDA or BLA prior to any commercial marketing or sale of 
the product in the United States. 
The development and approval process requires substantial time, effort and financial resources, and we 
cannot be certain that any approvals for our product candidates, or those of our collaborators, will be granted on a timely 
basis, if at all. 
The results of pre-clinical tests (which include laboratory evaluation as well as GLP studies to evaluate 
toxicity in animals) for a particular product candidate, together with related manufacturing information and analytical data, 
are submitted as part of an IND to the FDA. The IND automatically becomes effective 30 days after receipt by the FDA, 
unless the FDA, within the thirty-day time period, raises concerns or questions about the conduct of the proposed clinical 
trial, including concerns that human research subjects will be exposed to unreasonable health risks. In such a case, the IND 
sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. IND submissions may not 
result in FDA authorization to commence a clinical trial. A separate submission to an existing IND must also be made for 
each successive clinical trial conducted during product development. Further, an independent institutional review board 
("IRB") for each medical center proposing to conduct the clinical trial must review and approve the plan for any clinical 
trial before it commences at that center and it must monitor the study until completed. The FDA, the IRB or the sponsor 
may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being 
exposed to an unacceptable health risk. Clinical testing also must satisfy extensive good clinical practice (“GCP”) 
regulations and regulations for informed consent and privacy of individually identifiable information.
Clinical Trials. For purposes of an NDA or BLA submission and approval, clinical trials are typically 
conducted in the following sequential phases, which may overlap: 
•
Phase 1. Studies are initially conducted in a limited population to test the product candidate 
for safety, dose tolerance, absorption, distribution, metabolism, and excretion, often in 
healthy humans, but in some cases in patients. 
•
Phase 2. Studies are generally conducted in a limited patient population to identify possible 
adverse effects and safety risks, explore the initial efficacy of the product for specific 
targeted indications and to determine dose range or pharmacodynamics. Multiple Phase 2 
clinical trials may be conducted by the sponsor to obtain information prior to beginning 
larger and more expensive Phase 3 clinical trials. 
•
Phase 3. These are commonly referred to as pivotal studies. When Phase 2 evaluations 
demonstrate that a dose range of the product is effective and has an acceptable safety 
profile, Phase 3 clinical trials are undertaken in large patient populations to further evaluate 
dosage, provide substantial evidence of clinical efficacy and further test for safety in an 
expanded and diverse patient population at multiple, geographically dispersed clinical trial 
centers. 
•
Phase 4. The FDA may approve an NDA or BLA for a product candidate, but require that 
the sponsor conduct additional clinical trials to further assess the product after approval 
under a post-marketing commitment or post- marketing requirement. In addition, a sponsor 
may decide to conduct additional clinical trials after the FDA has approved a product. Post-
approval trials are typically referred to as Phase 4 clinical trials. 
14

The results of product development, pre-clinical studies and clinical trials are submitted to the FDA as part 
of an NDA or BLA. Applications also must contain extensive manufacturing and control information. Applications must be 
accompanied by a significant user fee. Once the submission has been accepted for filing, the FDA’s goal is to review 
applications within ten months of accepting the submission or, if the application relates to an unmet medical need in a 
serious or life-threatening indication, eight months from accepting the submission. During the review process, the FDA 
often has multiple requests for information or clarifications. The review process may be extended if the FDA deems that a 
response contains significant new information and will require additional time beyond the period originally designated to 
appropriately review. The FDA will typically conduct a pre-approval inspection of the manufacturer to ensure that the 
product can be reliably produced in compliance with cGMPs and will typically inspect certain clinical trial sites for 
compliance with GCP. The FDA may refer the application to an advisory committee for review, evaluation and 
recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an 
advisory committee, but it typically follows such recommendations. The FDA may deny approval of an application by 
issuing a Complete Response Letter if the applicable regulatory criteria are not satisfied. A Complete Response Letter may 
require additional clinical data and/or trial(s), and/or other significant, expensive and time-consuming requirements related 
to clinical trials, pre-clinical studies or manufacturing. Approval may occur with boxed warnings on product labeling or 
Risk Evaluation and Mitigation Strategies, which limit the labeling, distribution or promotion of a product. Once issued, 
the FDA may withdraw product approval if ongoing regulatory requirements are not met or if safety problems occur after 
the product reaches the market. In addition, the FDA may require testing, including Phase 4 clinical trials, and surveillance 
programs to monitor the safety effects of approved products which have been commercialized and the FDA has the power 
to prevent or limit further marketing of a product based on the results of these post-marketing programs or other 
information. 
Other Regulatory Requirements. Products manufactured or distributed pursuant to FDA approvals are 
subject to continuing regulation by the FDA, including recordkeeping, annual product quality review, payment of program 
user fees and reporting requirements. Adverse event experience with the product must be reported to the FDA in a timely 
fashion and pharmacovigilance programs to proactively look for these adverse events are mandated by the FDA. 
Manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies 
are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with ongoing 
regulatory requirements, including cGMPs, which impose certain procedural and documentation requirements upon us and 
our third-party manufacturers. Failure to comply with the statutory and regulatory requirements can subject a manufacturer 
to possible legal or regulatory action, such as suspension of manufacturing, seizure of product, injunctive action, additional 
reporting requirements and/or oversight by the agency, import alert or possible civil or criminal penalties. The FDA may 
also require us to recall a product from distribution or withdraw approval for that product. 
The FDA closely regulates the post-approval marketing and promotion of pharmaceuticals, including 
standards and regulations for direct-to-consumer advertising, dissemination of off-label information, industry-sponsored 
scientific and educational activities and promotional activities involving the internet, including certain social media 
activities. Further, if there are any modifications to the product, including changes in indications, labeling, or 
manufacturing processes or facilities, we may be required to submit and obtain FDA approval of a new or supplemental 
application, which may require us to develop additional data or conduct additional pre-clinical studies and clinical trials. 
Failure to comply with these requirements can result in adverse publicity, warning letters, corrective advertising and 
potential administrative, civil and criminal penalties, as well as damages, fines, withdrawal of regulatory approval, the 
curtailment or restructuring of our operations, the exclusion from participation in federal and state healthcare programs, 
additional reporting requirements and/or oversight by the agency, and imprisonment, any of which could adversely affect 
our ability to sell our products or operate our business and also adversely affect our financial results. 
Physicians may, in their independent medical judgment, prescribe legally available pharmaceuticals for 
uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such 
off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment 
for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of 
treatments. The FDA does, however, impose stringent restrictions on manufacturers’ communications regarding off-label 
use. Additionally, a significant number of pharmaceutical companies have been the target of inquiries and investigations by 
various U.S. federal and state regulatory, investigative, prosecutorial and administrative entities in connection with the 
promotion of products for off-label uses and other sales practices. These investigations have alleged violations of various 
U.S. federal and state laws and regulations, including claims asserting antitrust violations, violations of the Food, Drug and 
Cosmetic Act, false claims laws, anti-kickback laws, and other alleged violations in connection with the promotion of 
products for unapproved uses, pricing and Medicare and/or Medicaid reimbursement. If our promotional activities, 
including any promotional activities that a contracted sales force may perform on our behalf, fail to comply with these 
regulations or guidelines, we may be subject to warnings from, or enforcement action by, these authorities. In addition, our 
failure to follow FDA rules and guidelines relating to promotion and advertising may cause the FDA to issue warning 
letters or untitled letters, suspend or withdraw an approved product from the market, require corrective advertising or a 
15

recall or institute fines or civil fines, additional reporting requirements and/or oversight or could result in disgorgement of 
money, operating restrictions, injunctions or criminal prosecution, any of which could harm our business. 
Outside the United States, the ability of our partners and us to market a product is contingent upon 
obtaining marketing authorization from the appropriate regulatory authorities. The requirements governing marketing 
authorization, pricing and reimbursement vary widely from country to country and region to region. 
Clinical Trials in the EU. In the EU, clinical trials are governed by the Clinical Trials Regulation (EU) No 
536/2014 (“CTR”), which entered into application on January 31, 2022 repealing and replacing the former Clinical Trials 
Directive 2001/20 (“CTD”).
The CTR is intended to harmonize and streamline clinical trial authorizations, simplify adverse-
event reporting procedures, improve the supervision of clinical trials and increase transparency. Specifically, the regulation, 
which is directly applicable in all EU Member States, introduces a streamlined application procedure through a single-entry 
point, the "EU portal," the Clinical Trials Information System (“CTIS”); a single set of documents to be prepared and 
submitted for the application; as well as simplified reporting procedures for clinical trial sponsors. A harmonized procedure 
for the assessment of applications for clinical trials has been introduced and is divided into two parts. Part I assessment is 
led by the competent authorities of a reference Member State selected by the trial sponsor and relates to clinical trial 
aspects that are considered to be scientifically harmonized across EU Member States. This assessment is then submitted to 
the competent authorities of all concerned Member States in which the trial is to be conducted for their review. Part II is 
assessed separately by the competent authorities and Ethics Committees in each concerned EU Member State concerned. 
Individual EU Member States retain the power to authorize the conduct of clinical trials on their territory. 
The extent to which on-going clinical trials will be governed by the CTR will depend on the 
duration of the individual clinical trial. For clinical trials in relation to which an application for approval was made on the 
basis of the CTD before January 31, 2023, the CTD continued to apply on a transitional basis until January 31, 2025. All 
ongoing trials are now subject to the provisions of the CTR.  
In all cases, clinical trials must be conducted in accordance with GCP and the applicable regulatory 
requirements and the ethical principles that have their origin in the Declaration of Helsinki. Medicines used in clinical trials 
must be manufactured in accordance with the guidelines on cGMP and in a GMP licensed facility, which can be subject to 
GMP inspections.
European Union Marketing Authorization. To obtain a Marketing Authorization ("MA") for a product in 
the EU, an applicant must submit a Marketing Authorization Application ("MAA") either under a centralized procedure 
administered by the European Medicines Agency ("EMA") or one of the procedures administered by competent authorities 
in the EU Member States (decentralized procedure, national procedure or mutual recognition procedure). An MA may be 
granted only to an applicant established in the EU.
The centralized procedure provides for the grant of a single MA by the European Commission that is valid 
for all EU Member States. Pursuant to Regulation (EC) No 726/2004, the centralized procedure is compulsory for specific 
products, including for (i) medicinal products derived from biotechnological processes, (ii) products designated as orphan 
medicinal products, (iii) advanced therapy medicinal products ("ATMPs"), and (iv) products with a new active substance 
indicated for the treatment of HIV/AIDS, cancer, neurodegenerative diseases, diabetes, auto-immune and other immune 
dysfunctions and viral diseases. For products with a new active substance indicated for the treatment of other diseases and 
products that are highly innovative or for which a centralized process is in the interest of patients, the centralized procedure 
may be optional. 
Under the centralized procedure, the EMA’s Committee for Medicinal Products for Human Use ("CHMP") 
is responsible for conducting the initial assessment of a product. The CHMP is also responsible for several post-
authorization and maintenance activities, such as the assessment of modifications or extensions to an existing MA.
Under the centralized procedure in the EU, the maximum timeframe for the evaluation of an MAA is 210 
days, excluding clock stops when additional information or written or oral explanation is to be provided by the applicant in 
response to questions of the CHMP. Accelerated assessment may be granted by the CHMP in exceptional cases, when a 
medicinal product targeting an unmet medical need is expected to be of major interest from the point of view of public 
health and in particular from the viewpoint of therapeutic innovation. If the CHMP accepts a request for accelerated 
assessment, the time limit of 210 days will be reduced to 150 days (not including clock stops). The CHMP can, however, 
revert to the standard time limit for the centralized procedure if it considers that it is no longer appropriate to conduct an 
accelerated assessment.
16

Unlike the centralized authorization procedure, the decentralized MA procedure requires a separate 
application to, and leads to separate approval by, the competent authorities of each EU Member State in which the product 
is to be marketed. This application is identical to the application that would be submitted to the EMA for authorization 
through the centralized procedure. The reference EU Member State prepares a draft assessment and drafts of the related 
materials within 120 days after receipt of a valid application. The resulting assessment report is submitted to the concerned 
EU Member States who, within 90 days of receipt, must decide whether to approve the assessment report and related 
materials. If a concerned EU Member State cannot approve the assessment report and related materials due to concerns 
relating to a potential serious risk to public health, disputed elements may be referred to the Heads of Medicines Agencies’ 
Coordination Group for Mutual Recognition and Decentralised Procedures – Human ("CMDh") for review. The subsequent 
decision of the European Commission is binding on all EU Member States. 
The mutual recognition procedure allows companies that have a medicinal product already authorized in 
one EU Member State to apply for this authorization to be recognized by the competent authorities in other EU Member 
States. Like the decentralized procedure, the mutual recognition procedure is based on the acceptance by the competent 
authorities of the EU Member States of the MA of a medicinal product by the competent authorities of other EU Member 
States. The holder of a national MA may submit an application to the competent authority of an EU Member State 
requesting that this authority recognize the MA delivered by the competent authority of another EU Member State.
In principle, an MA has an initial validity of five years. The MA may be renewed after five years on the 
basis of a re-evaluation of the risk-benefit balance by the EMA or by the competent authority of the EU Member State in 
which the original MA was granted. To support the application, the MA holder must provide the EMA or the competent 
authority with a consolidated version of the eCTD (Common Technical Document) providing up-to-date data concerning 
the quality, safety and efficacy of the product, including all variations introduced since the MA was granted, at least nine 
months before the MA ceases to be valid. The European Commission or the competent authorities of the EU Member 
States may decide, on justified grounds relating to pharmacovigilance, to proceed with one further five year renewal period 
for the MA. Once subsequently definitively renewed, the MA shall be valid for an unlimited period. Any authorization 
which is not followed by the actual placing of the medicinal product on the EU market (in case of centralized procedure) or 
on the market of the authorizing EU Member State within three years after authorization ceases to be valid (the so-called 
sunset clause). 
Innovative products that target an unmet medical need and are expected to be of major public health interest 
may be eligible for a number of expedited development and review programs, such as the Priority Medicines ("PRIME") 
scheme, which provides incentives similar to the breakthrough therapy designation in the U.S. PRIME is a voluntary 
scheme aimed at enhancing the EMA’s support for the development of medicinal products that target unmet medical needs. 
It permits increased interaction and early dialogue with companies developing promising medicinal products, to optimize 
their product development plans and speed up their evaluation to help the product reach patients earlier than normal. 
Product developers that benefit from PRIME designation are potentially eligible for accelerated assessment of their MAA 
although this is not guaranteed. Benefits accrue to sponsors of product candidates with PRIME designation, including but 
not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and 
other development program elements, and potentially accelerated MAA assessment once a dossier has been submitted.
In the EU, a “conditional” MA may be granted in cases where all the required safety and efficacy data are 
not yet available. The conditional MA is subject to conditions to be fulfilled for generating the missing data or ensuring 
increased safety measures. It is valid for one year and must be renewed annually until all related conditions have been 
fulfilled. Once any pending studies are provided, the conditional MA can be converted into a traditional MA. However, if 
the conditions are not fulfilled within the timeframe set by the EMA, the MA will cease to be renewed. 
An MA may also be granted “under exceptional circumstances” where the applicant can show that it is 
unable to provide comprehensive data on the efficacy and safety under normal conditions of use even after the product has 
been authorized and subject to specific procedures being introduced. These circumstances may arise in particular when the 
intended indications are very rare and, in the state of scientific knowledge at that time, it is not possible to provide 
comprehensive information, or when generating data may be contrary to generally accepted ethical principles. Like a 
conditional MA, an MA granted in exceptional circumstances is reserved to medicinal products intended to be authorized 
for treatment of rare diseases or unmet medical needs for which the applicant does not hold a complete data set that is 
required for the grant of a standard MA. However, unlike the conditional MA, an applicant for authorization in exceptional 
circumstances is not subsequently required to provide the missing data. Although the MA “under exceptional 
circumstances” is granted definitively, the risk-benefit balance of the medicinal product is reviewed annually and the MA is 
withdrawn in case the risk-benefit ratio is no longer favorable.
17

In addition to an MA, various other requirements apply to the manufacturing and placing on the EU market 
of medicinal products. Manufacture of medicinal products in the EU requires a manufacturing authorization, and import of 
medicinal products into the EU requires a manufacturing authorization allowing for import. The manufacturing 
authorization holder must comply with various requirements set out in the applicable EU laws, regulations and guidance. 
These requirements include compliance with EU GMP standards when manufacturing medicinal products and active 
pharmaceutical ingredients ("APIs"), including the manufacture of APIs outside of the EU with the intention to import the 
APIs into the EU. Similarly, the distribution of medicinal products within the EU is subject to compliance with the 
applicable EU laws, regulations and guidelines, including the requirement to hold appropriate authorizations for 
distribution granted by the competent authorities of the EU Member States. MA holders and/or manufacturing and import 
authorization ("MIA") holders and/or distribution authorization holders may be subject to civil, criminal or administrative 
sanctions, including suspension of manufacturing authorization, in case of non-compliance with the EU or EU Member 
States’ requirements applicable to the manufacturing of medicinal products.
Data and Market Exclusivity. The EU provides opportunities for data and market exclusivity related to 
MAs. Upon receiving an MA, innovative medicinal products are generally entitled to receive eight years of data exclusivity 
and 10 years of market exclusivity. Data exclusivity, if granted, prevents regulatory authorities in the EU from referencing 
the innovator’s data to assess a generic application or biosimilar application for eight years from the date of authorization 
of the innovative product, after which a generic or biosimilar MAA can be submitted, and the innovator’s data may be 
referenced. The market exclusivity period prevents a successful generic or biosimilar applicant from commercializing its 
product in the EU until 10 years have elapsed from the initial MA of the reference product in the EU. The overall ten-year 
period may, occasionally, be extended for a further year to a maximum of 11 years if, during the first eight years of those 
ten years, the MA holder obtains an authorization for one or more new therapeutic indications which, during the scientific 
evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. 
However, there is no guarantee that a product will be considered by the EU’s regulatory authorities to be a new chemical/
biological entity, and products may not qualify for data exclusivity.
In the EU, there is a special regime for biosimilars, or biological medicinal products that are similar to a 
reference medicinal product but that do not meet the definition of a generic medicinal product. For such products, the 
results of appropriate preclinical or clinical trials must be provided in support of an application for MA. Guidelines from 
the EMA detail the type of quantity of supplementary data to be provided for different types of biological product. 
Pediatric Development. In the EU, Regulation (EC) No 1901/2006 provides that all MAAs for new 
medicinal products have to include the results of trials conducted in the pediatric population, in compliance with a pediatric 
investigation plan ("PIP") agreed with the EMA’s Pediatric Committee ("PDCO"). The PIP sets out the timing and 
measures proposed to generate data to support a pediatric indication of the medicinal product for which MA is being 
sought. The PDCO can grant a deferral of the obligation to implement some or all of the measures provided in the PIP until 
there are sufficient data to demonstrate the efficacy and safety of the product in adults. Further, the obligation to provide 
pediatric clinical trial data can be waived by the PDCO when these data are not needed or appropriate because the product 
is likely to be ineffective or unsafe in children, the disease or condition for which the product is intended occurs only in 
adult populations, or when the product does not represent a significant therapeutic benefit over existing treatments for 
pediatric patients. Once the MA is obtained in all EU Member States and study results are included in the product 
information, even when negative, the product is eligible for a six-month extension to the Supplementary Protection 
Certificate ("SPC") if any is in effect at the time of authorization or, in the case of orphan medicinal products, a two-year 
extension of orphan market exclusivity.
Post-Approval Requirements. Where an MA is granted in relation to a medicinal product in the EU, the 
holder of the MA is required to comply with a range of regulatory requirements applicable to the manufacturing, 
marketing, promotion and sale of medicinal products.
Similar to the United States, both MA holders and manufacturers of medicinal products are subject to 
comprehensive regulatory oversight by the EMA, the European Commission and/or the competent regulatory authorities of 
the individual EU Member States. The holder of an MA must establish and maintain a pharmacovigilance system and 
appoint an individual qualified person for pharmacovigilance who is responsible for oversight of that system. Key 
obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety update 
reports ("PSURs").
All new MAAs must include a risk management plan ("RMP") describing the risk management system that 
a company will put in place and documenting measures to prevent or minimize the risks associated with the product. The 
regulatory authorities may also impose specific obligations as a condition of the MA. Such risk-minimization measures or 
18

post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or the 
conduct of additional clinical trials or post-authorization safety studies.
In the EU, the advertising and promotion of medicinal products are subject to both EU and EU Member 
States’ laws governing promotion of medicinal products, interactions with physicians and other healthcare professionals, 
misleading and comparative advertising and unfair commercial practices. Although general requirements for advertising 
and promotion of medicinal products are established under EU directives, the details are governed by regulations in each 
Member State and can differ from one country to another. For example, applicable laws require that promotional materials 
and advertising in relation to medicinal products comply with the product’s Summary of Product Characteristics ("SmPC") 
as approved by the competent authorities in connection with an MA. The SmPC is the document that provides information 
to physicians concerning the safe and effective use of the product. Promotional activity that does not comply with the 
SmPC is considered off-label and is prohibited in the EU. Direct-to-consumer advertising of prescription medicinal 
products is also prohibited in the EU.
Medicinal Products in the UK and Brexit. The United Kingdom’s (“UK”) withdrawal from the EU 
on January 31, 2020, commonly referred to as Brexit, has changed the regulatory relationship between the UK and the EU. 
The Medicines and Healthcare products Regulatory Agency (“MHRA”) is now the UK’s standalone regulator for 
medicinal products and medical devices. The UK is now a third country to the EU.
The UK regulatory framework in relation to clinical trials is governed by the Medicines for Human 
Use (Clinical Trials) Regulations 2004, as amended, which is derived from the CTD, as implemented into UK national law 
through secondary legislation. On January 17, 2022, the MHRA launched an eight-week consultation on reframing the UK 
legislation for clinical trials. The UK Government published its response to the consultation on March 21, 2023 confirming 
that it would bring forward changes to the legislation. These resulting legislative amendments, if implemented in their 
current form, bring the UK into closer alignment with the CTR. In October 2023, the MHRA announced a new Notification 
Scheme for clinical trials which enables a more streamlined and risk-proportionate approach to initial clinical trial 
applications for Phase 4 and low-risk Phase 3 clinical trial applications.
Marketing authorizations in the UK are governed by the Human Medicines Regulations (SI 
2012/1916), as amended. Since January 1, 2021, an applicant for the EU centralized procedure marketing authorization can 
no longer be established in the UK. As a result, since this date, companies established in the UK cannot use the EU 
centralized procedure. 
In order to obtain a UK MA to commercialize products in the UK, an applicant must be established 
in the UK and must follow one of the UK national authorization procedures or one of the remaining post-Brexit 
international cooperation procedures. Applications are governed by the Human Medicines Regulations (SI 2012/1916) and 
are made electronically through the MHRA Submissions Portal. The MHRA has introduced changes to national licensing 
procedures, including procedures to prioritize access to new medicines that will benefit patients, a 150-day assessment 
(subject to clock-stops) and a rolling review procedure. The rolling-review procedure permits the separate or joint 
submission of quality, non-clinical, and clinical data to the MHRA which can be reviewed on a rolling basis. After an 
application under the rolling-review procedure has been validated, the decision should be received within 100 days (subject 
to clock-stops). 
In addition, since January 1, 2024, the MHRA may rely on the International Recognition Procedure 
(“IRP”), when reviewing certain types of MAAs. Pursuant to the IRP, the MHRA will take into account the expertise and 
decision-making of trusted regulatory partners (e.g., the regulatory in Australia, Canada, Switzerland, Singapore, Japan, the 
U.S.A. and the EU). The MHRA will conduct a targeted assessment of IRP applications but retain the authority to reject 
applications if the evidence provided is considered insufficiently robust. The IRP allows medicinal products approved by 
such trusted regulatory partners that meet certain criteria to undergo a fast-tracked MHRA review to obtain and/or update a 
MA in the UK. Applications should be decided within a maximum of (i) 60 days if there are no major objections identified 
that cannot be resolved within such 60 day period and the approval from the trusted regulatory partner selected has been 
granted within the previous 2 years, or (ii) 110 days if major objections are identified or such approval has not been granted 
within the previous 2 years. Applicants can submit initial MAAs to the IRP but the procedure can also be used throughout 
the lifecycle of a product for post-authorization procedures including line extensions, variations and renewals.
All existing EU marketing authorizations for centrally authorized products were automatically 
converted or grandfathered into UK marketing authorizations, effective in the UK only, free of charge on January 1, 2021, 
unless the marketing authorization holder opted-out of this possibility. Northern Ireland remained within the scope of EU 
authorizations in relation to centrally authorized medicinal products until January 1, 2025. However, on January 1, 2025, a 
new arrangement as part of the so-called “Windsor Framework” came into effect and reintegrated Northern Ireland under 
the regulatory authority of the MHRA with respect to medicinal products. The Windsor Framework removes EU licensing 
19

processes and EU labeling and serialization requirements in relation to Northern Ireland and introduces a UK-wide 
licensing process for medicines. 
Healthcare Fraud and Abuse Laws. As a pharmaceutical company, certain federal and state healthcare laws 
and regulations pertaining to fraud and abuse and patients’ rights may be applicable to our business. We may be subject to 
various federal, state and foreign laws targeting fraud and abuse in the healthcare industry. For example, in the United 
States, there are federal and state anti-kickback laws that prohibit the payment or receipt of kickbacks, bribes or other 
remuneration intended to induce the purchase or recommendation of healthcare products and services or reward past 
purchases or recommendations. These laws are applicable to manufacturers of products regulated by the FDA, such as us, 
and pharmacies, hospitals, physicians and other potential purchasers of such products. 
The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, receiving, 
offering or paying remuneration, directly or indirectly, to induce either the referral of an individual, or the furnishing, 
recommending, or arranging for a good or service, for which payment may be made, in whole or in part, under a federal 
healthcare program, such as the Medicare and Medicaid programs. The term “remuneration” is defined as any 
remuneration, direct or indirect, overt or covert, in cash or in kind, and has been broadly interpreted to include anything of 
value, including for example, gifts, discounts, the furnishing of supplies or equipment, credit arrangements, payments of 
cash, waivers of payment, ownership interests and providing anything at less than its fair market value. Several courts have 
interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to 
induce referrals of federal healthcare covered business, the statute may have been violated, and enforcement will depend on 
the relevant facts and circumstances. The Patient Protection and Affordable Care Act of 2010, as amended by the Health 
Care and Education Reconciliation Act of 2010 (collectively, the "ACA"), among other things, amended the intent 
requirement of the federal Anti-Kickback Statute to state that a person or entity need not have actual knowledge of this 
statute or specific intent to violate it in order to have committed a violation. In addition, the ACA provides that the 
government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback 
Statute constitutes a false or fraudulent claim for purposes of the False Claims Act (discussed below) or the civil monetary 
penalties statute, which imposes penalties against any person who is determined to have presented or caused to be 
presented a claim to a federal health program that the person knows or should know is for an item or service that was not 
provided as claimed or is false or fraudulent, or to have offered improper inducements to federal health care program 
beneficiaries to select a particular provider or supplier. The federal Anti-Kickback Statute is broad, and despite a series of 
narrow statutory exceptions and regulatory safe harbors, prohibits many arrangements and practices that are lawful in 
businesses outside of the healthcare industry. Many states have also adopted laws similar to the federal Anti-Kickback 
Statute, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only 
the Medicare and Medicaid programs, and do not contain identical safe harbors. In addition, where such activities involve 
foreign government officials, they may also potentially be subject to the Foreign Corrupt Practices Act. Because of the 
breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available, it is possible that 
some of our business activities, including our activities with physician customers, pharmacies, and patients, as well as our 
activities pursuant to partnerships with other companies and pursuant to contracts with contract research organizations, 
could be subject to challenge under one or more of such laws. 
The federal criminal and civil false claims laws, including the False Claims Act, which prohibits any person 
from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly 
making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal 
government. A claim includes “any request or demand” for money or property presented to the U.S. government. In 
addition, the ACA specified that a claim including items or services resulting from a violation of the federal Anti-Kickback 
Statute constitutes a false or fraudulent claim for purposes of the False Claims Act. The False Claims Act has been the 
basis for numerous enforcement actions and settlements by pharmaceutical and other healthcare companies in connection 
with various alleged financial relationships with customers. In addition, a number of pharmaceutical manufacturers have 
reached substantial financial settlements in connection with allegedly causing false claims to be submitted because of the 
companies’ marketing of products for unapproved, and thus non-reimbursable, uses. Certain marketing practices, including 
off-label promotion, may also violate false claims laws, as might violations of the federal physician self-referral laws, such 
as the Stark laws, which prohibit a physician from making a referral to certain designated health services with which the 
physician or the physician’s family member has a financial interest and prohibit submission of a claim for reimbursement 
pursuant to the prohibited referral. The “qui tam” provisions of the False Claims Act allow a private individual to bring 
civil actions on behalf of the federal government alleging that the defendant has submitted a false claim to the federal 
government, and to share in any monetary recovery. In addition, various states have enacted similar fraud and abuse 
statutes or regulations, including, without limitation, false claims laws analogous to the False Claims Act that apply to 
items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. 
Separately, there are a number of other fraud and abuse laws that pharmaceutical manufacturers must be 
mindful of, particularly after a product candidate has been approved for marketing in the United States. For example, a 
20

federal criminal law enacted as part of, the Health Insurance Portability and Accountability Act of 1996 ("HIPAA") 
prohibits, among other things, knowingly and willfully executing a scheme to defraud any healthcare benefit program, 
including private third-party payors. The false statements statute prohibits knowingly and willfully falsifying, concealing or 
covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery 
of or payment for healthcare benefits, items or services. There are also federal and state consumer protection and unfair 
competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers. 
Healthcare Privacy and Security Laws. We are subject to, or our marketing activities may be limited by, 
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 ("HITECH") 
and their respective implementing regulations, which established uniform standards for certain “covered entities” (certain 
healthcare providers, health plans and healthcare clearinghouses) governing the conduct of certain electronic healthcare 
transactions and protecting the security and privacy of protected health information. Among other things, HIPAA’s privacy 
and security standards are directly applicable to “business associates” — independent contractors or agents of covered 
entities that create, receive, maintain or transmit protected health information in connection with providing a service for or 
on behalf of a covered entity, as well as their covered subcontractors. In addition to possible civil and criminal penalties for 
violations, HITECH created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties 
directly applicable to business associates, and gave state attorneys general authority to file civil actions for damages or 
injunctions in federal courts to enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil 
actions. State laws also govern the privacy and security of health information in certain circumstances, many of which 
differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Further, 
we are required to comply with international personal data protection laws and regulations, particularly as the result of our 
operations in Düsseldorf, Germany. 
Privacy and Security Laws. We are subject to diverse laws and regulations relating to data privacy and 
security, including HIPAA in the United States, the European Union's General Data Protection Regulation ("EU GDPR") 
in the European Economic Area ("EEA"), and the UK's General Data Protection Regulation ("UK GDPR"). New privacy 
rules are being enacted in the United States and globally, and existing ones are being expanded, updated and strengthened.
For example, the EU GDPR imposes strict requirements on the processing of personal data, which apply to 
non-EU entities that process, or control the processing of, the personal information of EU subjects, including clinical trial 
data. The EU GDPR implements more stringent operational requirements than its predecessor legislation.
Also, the California Consumer Privacy Act of 2018 (“CCPA”) establishes a privacy framework for covered 
businesses, including an expansive definition of personal information and data privacy rights for California residents. The 
CCPA includes a framework with potentially severe statutory damages and private rights of action. The CCPA requires 
covered companies to provide new disclosures to California consumers (as that word is broadly defined in the CCPA), 
provide such consumers new ways to opt-out of certain sales of personal information, and allow for a new cause of action 
for data breaches. 
Further, the California Privacy Rights Act ("CPRA") significantly modifies the CCPA, including by 
expanding consumers’ rights with respect to certain sensitive personal information. The CPRA also created a state agency 
that is vested with authority to implement and enforce the CCPA and the CPRA.
“Sunshine” and Marketing Disclosure Laws. There are an increasing number of federal and state 
“sunshine” laws and equivalent foreign laws that require pharmaceutical manufacturers to make reports to states and 
equivalent foreign authorities on pricing and marketing information. Several states and local jurisdictions and equivalent 
foreign laws have enacted legislation requiring pharmaceutical companies to, among other things, establish marketing 
compliance programs, file periodic reports with the state, make periodic public disclosures on sales and marketing 
activities, register pharmaceutical sales representatives, and prohibiting certain other sales and marketing practices. In 
addition, a similar federal requirement, known as the Physician Payments Sunshine Act, requires manufacturers, including 
pharmaceutical manufacturers, to track and report annually to the federal government certain payments and other transfers 
of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other 
healthcare professionals (such as physician assistants and nurse practitioners) and teaching hospitals and information 
regarding ownership or investment interests held by such physicians and their immediate family members. The federal 
government discloses the reported information on a publicly available website. Certain states, such as Massachusetts, also 
make the reported information publicly available. Some foreign jurisdictions, including a number of EU Member States, 
impose equivalent requirements. In addition, there are state and local laws that require pharmaceutical representatives to be 
licensed and comply with codes of conduct, transparency reporting, and other obligations. These laws may adversely affect 
our sales, marketing, and other activities with respect to our products in the United States and on some foreign markets by 
21

imposing administrative and compliance burdens on us. If we fail to track and report as required by these laws or otherwise 
comply with these laws, we could be subject to the penalty provisions of the pertinent state and federal authorities.
Government Price Reporting. We are required to discount such products to authorized users of the Federal 
Supply Schedule of the General Services Administration, under which additional laws and requirements apply. These 
programs require submission of pricing data and calculation of discounts pursuant to complex statutory formulas, as well as 
the entry into government procurement contracts governed by the Federal Acquisition Regulations, and the guidance 
governing such calculations is not always clear. Compliance with such requirements can require significant investment in 
personnel, systems and resources, but failure to properly calculate our prices or offer required discounts could subject us to 
substantial penalties.
Penalties. Because of the breadth of these laws and the narrowness of available statutory exception and 
regulatory safe harbors, it is possible that some of our business activities in the United States could be subject to challenge 
under one or more of such laws. Moreover, state governmental agencies may propose or enact laws and regulations that 
extend or contradict federal requirements. If we or our operations are found to be in violation of any of the state or federal 
laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including 
significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from 
participation in U.S. federal or state healthcare programs, additional reporting requirements and/or oversight, if subject to a 
corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, exclusion 
from participation in federal healthcare programs, contractual damages, reputational harm, diminished profits and future 
earnings, and the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment or restructuring 
of our operations could materially adversely affect our ability to operate our business and our financial results. Although 
compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, the risks cannot be 
entirely eliminated. Any action against us for violation of these laws, even if we successfully defend against it, could cause 
us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, 
achieving and sustaining compliance with applicable federal and state privacy, security, sunshine, government price 
reporting, and fraud laws may prove costly.
Coverage and Reimbursement. Sales of any marketed product, in particular for HEPLISAV-B, depend, in 
part, on the extent to which such product will be covered by third-party payors, such as federal, state, and foreign 
government healthcare programs, commercial insurance and managed healthcare organizations, and the level of 
reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of 
reimbursement to be provided are made on a plan-by-plan basis. These third-party payors are increasingly reducing 
coverage and reimbursement for medical products, drugs and services. Further, coverage policies and reimbursement rates 
may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for 
which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in 
the future. In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost-
containment programs, including price controls, restrictions on coverage and reimbursement and requirements for 
substitution of generic products. For example, the newly elected Presidential administration may be more skeptical of the 
safety and efficacy of vaccine products, which could lead to increased regulatory scrutiny and more restrictive coverage 
policies regarding vaccine products. Adoption of price controls and cost-containment measures, and adoption of more 
restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. Decreases 
in third-party reimbursement for any marketed product or a decision by a third-party payor not to cover a market product 
could reduce physician usage and patient demand for the product and also have a material adverse effect on sales. 
Impact of Healthcare Reform and Recent Public Scrutiny of Specialty Drug Pricing on Coverage, 
Reimbursement, and Pricing. In the United States and other potentially significant foreign markets for our products, federal 
and state authorities as well as third-party payors are increasingly attempting to limit or regulate the price of medical 
products and services, particularly for new and innovative products and therapies, which has resulted in lower average net 
selling prices. Further, there is increased scrutiny of prescription drug pricing practices by federal and state lawmakers and 
enforcement authorities. In addition, there is an emphasis on managed healthcare in the United States, which will put 
additional pressure on product pricing, reimbursement and usage, which may adversely affect our future product sales and 
results of operations. These pressures can arise from rules and practices of managed care groups, judicial decisions and 
governmental laws and, in the US, regulations related to Medicare, Medicaid and healthcare reform, pharmaceutical 
reimbursement policies and pricing in general. 
There also has been particular and increasing legislative and enforcement interest in the United States with 
respect to specialty drug pricing practices, particularly with respect to drugs that have been subject to relatively large price 
increases over relatively short time periods. Such interest has resulted in several recent U.S. Congressional inquiries and 
proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug 
pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under 
22

Medicare, and reform government program reimbursement methodologies for drugs. For example, on August 16, 2022, the 
Inflation Reduction Act of 2022 (“IRA”) was signed into law, which among other things, (1) directs the U.S. Department 
of Health and Human Services (“HHS”) to negotiate the price of certain single-source biologics that have been on the 
market for at least 11 years covered under Medicare (the “Medicare Drug Price Negotiation Program”) and (2) imposes 
rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions 
began to take effect progressively in fiscal year 2023. On August 15, 2024, HHS announced the agreed-upon price of the 
first ten drugs that were subject to price negotiations, although the Medicare Drug Price Negotiation Program is currently 
subject to legal challenges. On January 17, 2025, HHS selected fifteen additional products covered under Part D for price 
negotiation in 2025. Each year thereafter more Part B and Part D products will become subject to the Medicare Drug Price 
Negotiation Program. Further, on December 7, 2023, an initiative to control the price of prescription drugs through the use 
of march-in rights under the Bayh-Dole Act was announced. On December 8, 2023, the National Institute of Standards and 
Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In 
Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise 
march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the 
new framework. At the state level, legislatures have increasingly passed legislation and implemented regulations designed 
to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, 
restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, 
designed to encourage importation from other countries and bulk purchasing. For example, on January 5, 2024, the FDA 
approved Florida’s Section 804 Importation Program ("SIP") proposal to import certain drugs from Canada for specific 
state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and 
whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals 
that are pending review by the FDA. Any such approved importation plans, when implemented, may result in lower drug 
prices for products covered by those programs. Additionally, in California, effective January 1, 2019, drug companies must 
notify insurers and government regulators of certain price increases and provide an explanation of the reasons for such 
increases. 
In addition, in the United States, the pharmaceutical industry has already been significantly affected by 
major legislative initiatives, including, for example, the ACA. The ACA, among other things, imposes a significant annual 
fee on companies that manufacture or import branded prescription drug products. It also contains substantial provisions 
intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, and impose 
additional health policy reforms, any or all of which may affect our business. 
There have been judicial, Congressional, and executive branch challenges to certain aspects of the ACA. 
For example, the IRA, among other things, extends enhanced subsidies for individuals purchasing health insurance 
coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part 
D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new 
manufacturer discount program. It is possible that the ACA will be subject to judicial or Congressional challenges in the 
future. It is unclear how such challenges and the healthcare reform measures of the second Trump administration will 
impact the ACA.
Other legislative changes have also been proposed and adopted since the ACA was enacted. For example, 
the Budget Control Act of 2011 resulted in aggregate reductions in Medicare payments to providers of up to two percent 
per fiscal year, starting in 2013 and, due to subsequent legislative amendments to the statute, will remain in effect until 
2032 unless additional Congressional action is taken. Such laws, and others that may affect our business that have been 
recently enacted or may in the future be enacted, may result in additional reductions in Medicare and other healthcare 
funding. 
Moreover, in the EEA some countries require the completion of additional studies that compare the cost-
effectiveness of a particular medicinal product candidate to currently available therapies. In December 2021, Regulation 
No 2021/2282 on Health Technology Assessment ("HTA") Regulation, was adopted in the EU. This HTA process, which 
is currently governed by the national laws of the individual EU Member States, is the procedure according to which the 
assessment of the public health impact, therapeutic impact and the economic and societal impact of use of a given 
medicinal product in the national healthcare systems of the individual country is conducted. The outcome of HTA 
regarding specific medicinal products will often influence the pricing and reimbursement status granted to these medicinal 
products by the competent authorities of individual EU Member States. The HTA Regulation is intended to boost 
cooperation among Member States in assessing health technologies, including new medicinal products, and providing the 
basis for cooperation at the level of the EU for joint clinical assessments in these areas. The HTA Regulation has applied 
from January 12, 2025. Although it will enter into force iteratively and initially apply to new active substances to treat 
cancer and to all advanced therapy medicinal products (ATMPs), it will then be expanded to orphan medicinal products in 
January 2028, and to all centrally authorized medicinal products as of 2030. Selected high-risk medical devices will also be 
assessed under the HTA Regulation as of 2026. The HTA Regulation is intended to harmonize the clinical benefit 
assessment of HTA across the EU. Pricing and reimbursement decisions, based on these assessments, remain the 
responsibility of individual Member States. In light of the fact that the UK has left the EU, Regulation No 2021/2282 on 
23

HTA does not apply in the UK. However, the UK Medicines and Healthcare products Regulation Agency (“MHRA”) is 
working with UK HTA bodies and other national organizations, such as the Scottish Medicines Consortium (“SMC”), the 
National Institute for Health and Care Excellence (“NICE”), and the All-Wales Medicines Strategy Group, to introduce 
new pathways supporting innovative approaches to the safe, timely and efficient development of medicinal products, 
including, effective as of March 31, 2025, relaunching the Innovative Licensing and Access Pathway with more predicable 
timelines and closer involvement of the National Health Service.
MANUFACTURING
We rely on our facility in Düsseldorf, Germany and third parties to perform the multiple processes involved 
in manufacturing HBsAg for use in HEPLISAV-B, the combination of the oligonucleotide and the antigens, and 
formulation, fill and finish. As is common in our industry, in light of FDA inspection and licensing requirements for 
manufacturing sites, we have relied on a limited number of suppliers to produce oligonucleotides for clinical trials and 
conduct formulation, fill and finish operations. We rely on a single supplier to produce our CpG 1018 adjuvant for 
HEPLISAV-B and for our collaborators. Switching suppliers, or bringing on additional suppliers, could be complicated and 
time consuming, but we generally seek to maintain inventory to help bridge any unexpected gap in supply. In order to help 
us successfully manufacture and commercialize HEPLISAV-B, we have secured long-term supply agreements with the key 
third-party suppliers and vendors for commercial supply of our component products and finished goods. We currently 
manufacture the HBsAg for HEPLISAV-B at our Dynavax GmbH facility. 
COMMITMENT TO COMPLIANCE AND ENVIRONMENT
We are committed to conducting our business in compliance with all applicable legal and ethical standards. 
In addition, we are committed to helping to protect the environment.
Our Ethics and Compliance program includes our Code of Business Conduct and Ethics (“Code”), which 
sets forth our expectations of all Dynavax directors, officers and employees globally that they conduct their business 
activities in a legal and ethical manner. The Code can be found on our website under the header “Investors” and within that 
under the header “Corporate Governance and Compliance.” We have a Chief Ethics and Compliance Officer, a Compliance 
Steering Committee and policies, procedures and training addressing specific aspects of our business, including advertising 
and promotion; engagements with healthcare providers; and regarding our business activities outside the United States to 
ensure they comply with the U.S. Foreign Corrupt Practices Act and all other applicable anti-corruption laws. We certify 
on an annual basis to having a comprehensive compliance program that meets the standards set forth under California law. 
This certification, which sets forth all of the elements of our healthcare compliance program, can be found on our website.
We also care about the environment. To that end, our headquarters is in a building certified as “Gold” level 
on the LEED Scorecard as set forth by the United States Green Building Committee. Our transition to a largely virtual 
environment has further helped reduce congestion and pollution. Our relatively small headquarters space (approximately 
8,000 square feet) has further reduced our carbon footprint. In addition, we participate in our building's active recycling 
program. We continue to consider other ways in which we can conduct our business in an environmentally friendly 
manner.
We have made, and will continue to make, expenditures for environmental compliance and protection. We 
do not expect that expenditures for compliance with environmental laws will have a material effect on our results of 
operations in the future.
HUMAN CAPITAL MANAGEMENT
As of December 31, 2024, we had 405 employees, comprised of 260 employees in the U.S., including 103 
members of our field sales team located throughout the U.S., as well as 145 employees in our office and manufacturing 
facility in Düsseldorf, Germany. Many of our employees hold advanced degrees, including Masters degrees and Pharm.D., 
Ph.D., M.D. or J.D. degrees. We consider the intellectual capital of our employees to be an essential driver of our business 
and key to our future prospects. None of our employees is subject to a collective bargaining agreement or represented by a 
trade or labor union. We consider our relations with our employees to be very good.
Retention and Compensation 
Our regrettable turnover rate for 2024 was 6% in the U.S. and 5% in Düsseldorf. Despite these low 
turnover rates, as a vaccine-focused company, we face stiff competition to hire and retain our employees. The average 
24

tenure among our employees is 3.7 years in the U.S. and 6.1 years in Düsseldorf. We also believe that our remote-first 
working environment in the U.S. serves as a useful recruiting and retention tool. 
We monitor our compensation programs closely and provide what we consider to be a very competitive 
mix of compensation and insurance benefits for all our employees, which includes base salary, annual cash bonus 
opportunity or semi-annual sales incentive bonus for our field sales team, comprehensive benefits package and equity 
compensation. Each of our employees participates in our equity programs. The annual cash bonus opportunity and equity 
compensation generally increase as a percentage of total compensation based on level of responsibility. Any actual cash 
bonus payout for our employees is based on a combination of our performance against corporate goals and individual 
performance, with the exception of any actual cash bonus payouts to our Chief Executive Officer and President which is 
based solely on our performance against corporate goals. The mix of equity compensation also shifts based on the level of 
responsibility; employees below the senior director level typically receive 100 percent of their equity compensation in 
restricted stock units, while more senior level employees typically receive a mix of stock options and restricted stock units. 
Annual equity awards to our senior leadership team include performance-based restricted stock units.
Employee Development and Workplace Culture
Attracting and retaining top talent is key to the achievement of our strategic goals. The development and 
engagement of our employees is also a top priority of the human resources team. We perform annual performance reviews 
of all employees, and we seek employee feedback in a variety of ways, including annual employee surveys. In 2024, 29 
leaders and key contributors completed a leadership development program, in addition to the 32 who participated in the 
prior year. Our senior management and human resources team periodically undertake comprehensive organizational 
reviews. In addition, we have an extensive series of employee training programs on business ethics and compliance 
matters, including required annual trainings on our Code, our Anti-Corruption Compliance Policy and certain cybersecurity 
topics. Also, depending on employee roles and departments, we have employee training programs on medical affairs, 
commercial, sales and other matters.
The development and engagement of our employees is among our top priorities. We remain committed to 
living out our core values and in creating a culture where every employee is recognized and appreciated for the unique 
individuals they are. Our work related to these commitments focus on community outreach and engagement as well as 
efforts to support leadership excellence and career development for all employees. As a vaccine company, bettering public 
health is core to our mission, and that responsibility reaches to bettering the lives of our employees and broader 
communities.
In 2024, we were certified as a Great Place To Work for the second year in a row. In addition, we were 
named by Fortune as one of the Best Places to Work in small to medium sized biotech companies in the United States.

Risks Related to our Business and Capital Requirements
HEPLISAV-B has been approved in the United States, the European Union and the United Kingdom and launched in 
the United States and Germany, and there is significant competition in these marketplaces. Since this is our first 
marketed product, the timing of uptake and distribution efforts are unpredictable and there is a risk that we may not 
achieve and sustain commercial success for HEPLISAV-B.
We have established sales, marketing and distribution capabilities and commercialized HEPLISAV-B in the 
United States and Germany. We have also received approval in the European Union and the United Kingdom for 
HEPLISAV-B. Successful commercialization of HEPLISAV-B in these regions or elsewhere will require significant 
resources and time, and there can be no certainty that we will succeed in these efforts. While our personnel are experienced 
with respect to marketing of healthcare products, because HEPLISAV-B is our first marketed product, the potential uptake 
of the product through distribution, and the timing, trajectory, rate and sustainability for growth in sales is unpredictable, 
and we may not be successful in commercializing HEPLISAV-B in the long term. In particular, successful 
commercialization of HEPLISAV-B will require that we continue to negotiate and enter into contracts with wholesalers, 
distributors, group purchasing organizations, and other parties, and that we maintain those contractual relationships. There 
is a risk that we may fail to complete or maintain some or all of these important contracts on favorable terms or at all, or 
that in a potentially evolving reimbursement environment, our efforts may fail to overcome established competition at 
favorable pricing, or at all.
We have continued to expand our field sales force. As these teams expand, it will take time for our 
expanded teams to generate significant sales momentum, if they do so at all. Although we have had some success growing 
and developing our field sales force following the launch of HEPLISAV-B, there is no guarantee that we will be able to 
generate sales at the same or improved rates going forward, if at all. In addition, retention of capable sales personnel may 
be more difficult for us compared to our competitors, as we focus on a single product offering. We must retain our sales 
force in order for HEPLISAV-B to maintain or expand its commercial presence.
Moreover, we expect that we will need to divert resources in order to successfully market, sell and 
distribute HEPLISAV-B for use with dialysis patients, one of our targeted patient populations. We do not yet have 
approval to market the regimen for dialysis. In the second quarter of 2024, the FDA issued a Complete Response Letter 
(“CRL”) for the supplemental Biologics License Application (“sBLA”) to include a four-dose regimen for adults on 
hemodialysis in the U.S. label, and we are exploring approaches to address the deficiencies noted in the CRL. In the fourth 
quarter of 2024, we received feedback from the FDA regarding the potential to conduct an observational retrospective 
cohort study to support our sBLA filing for adults on hemodialysis. We expect to resubmit our sBLA for HEPLISAV-B 
vaccination of adults on hemodialysis to the FDA in 2025. We may be unsuccessful in conducting an observational 
retrospective cohort study, may not successfully resubmit our sBLA for a four-dose regimen for adults on hemodialysis, 
and may never obtain FDA approval for such indication, which would limit our addressable market and revenue.  Although 
the Centers for Disease Control and Prevention (“CDC”) and the CDC’s Advisory Committee on Immunization Practices 
(“ACIP”) recommend that all adults aged 19-59, including patients on dialysis, receive hepatitis B vaccinations, our 
predictions of how many of those patients actually receive HEPLISAV-B may be inaccurate. In particular, vaccine 
skepticism and disinformation may impact the willingness of patients to consider hepatitis B vaccination.
In addition to the risks with employing and maintaining our own commercial capabilities and with 
contracting, other factors that may inhibit our efforts to successfully commercialize HEPLISAV-B include:
•
whether we are able to continue recruiting and retaining adequate numbers of effective sales 
and marketing personnel;
•
whether we are able to access key health care providers to discuss HEPLISAV-B;
•
whether we can continue to compete successfully as a relatively new entrant in established 
distribution channels for vaccine products; and
•
whether we will maintain sufficient financial resources to cover the costs and expenses 
associated with sustaining a capable sales and marketing organization and related 
commercial infrastructure.
If we are not able to enter new markets ourselves, we may be required to collaborate or partner 
HEPLISAV-B with a third-party pharmaceutical or biotechnology company with existing products. To the extent we 
collaborate or partner, as we have done for HEPLISAV-B distribution in Germany, the product’s financial value will be 
shared with another party and we will need to establish and maintain a successful collaboration arrangement, and we may 
not be able to enter into these arrangements on acceptable terms or in a timely manner in order to establish HEPLISAV-B 
in these new markets. To the extent that we enter into co-promotion or other arrangements, any revenues we receive will 
depend upon the efforts of third parties, which may not be successful and are only partially in our control. In that event, our 
product revenues may be lower than if we marketed and sold our products directly with the highest priority, and we may be 
26

required to reduce or eliminate much of our commercial infrastructure and personnel as a result of such collaboration or 
partnership.
Governments influence the price of medicinal products in the European Union through their pricing and 
reimbursement rules and control of national healthcare systems that fund a large part of the cost of those products to 
consumers. Even though we have been granted a marketing authorization in the European Union for HEPLISAV-B, we 
have yet to obtain broad reimbursements and pricing approval in any European Union Member State and rely on our 
distributor to do so, who currently only markets in Germany. Some jurisdictions operate positive and negative list systems 
under which products may only be marketed once a reimbursement price has been agreed. To obtain reimbursement or 
pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness 
of a particular product candidate to currently available therapies. Other European Union Member States allow companies to 
fix their own prices for medicines, but monitor and control company profits. Any delay in being able to market our 
products in the European Union, the United Kingdom or elsewhere may adversely affect our business and financial 
condition.
If we, or our partners, are not successful in setting our marketing, pricing and reimbursement strategies, 
recruiting and maintaining effective sales and marketing personnel or building and maintaining the infrastructure to support 
commercial operations in the U.S., Germany and elsewhere, we will have difficulty successfully commercializing 
HEPLISAV-B, which would adversely affect our business and financial condition. 
Our financial results may vary significantly from quarter to quarter or may fall below the expectations of investors or 
securities analysts, each of which may adversely affect our stock price.
Numerous factors, many of which are outside our control, may cause or contribute to significant 
fluctuations in our quarterly and annual operating results. For example, during the year ended December 31, 2022, we 
recognized $587.7 million of CpG 1018 adjuvant revenue. However, our CpG 1018 adjuvant supply agreements expired at 
the end of 2022, and as a result, we did not recognize CpG 1018 adjuvant revenue for the years ended December 31, 2024 
and December 31, 2023. Similarly, if demand for HEPLISAV-B decreases from recent trends for any reason, that could 
also cause unexpected fluctuations in our quarterly and annual operating results.
The occurrence and timing of any transfer of control of product sold to customers can also be difficult to 
predict, and the recognition of revenue can vary widely depending on timing of product deliveries and satisfaction of other 
obligations. As an example, any future revenue we do receive from sales of our CpG 1018 adjuvant has been and will 
continue to be difficult to predict, if it materializes at all. Historically, we generally required customers to place orders for 
CpG 1018 adjuvant with at least six months lead time and to make an advance payment toward the finished order. Where 
we receive such advance payments, we record such payments as deferred revenue until we have delivered the adjuvant and 
met all criteria to recognize revenue. In accordance with our stated revenue policy, we historically recorded revenue for 
these contracts upon meeting all of the criteria for revenue recognition under Accounting Standards Codification 606, 
which includes, among other criteria, the transfer of control for CpG 1018 adjuvant to our customer. During the year ended 
December 31, 2024 and December 31, 2023, we did not receive any advanced payments from any of our customers to 
purchase CpG 1018 adjuvant. Our collaborators in many cases have purchase agreements with government agencies. If our 
collaborators do not receive payment from these agencies for any past or future adjuvant orders, our ability to collect our 
own receivables may be adversely affected. For example, as of December 31, 2023, we had recorded an allowance for 
doubtful accounts of $12.3 million in connection with our accounts receivable balance due from Bio E, which was 
determined by assessing changes in Bio E’s credit risk, contemplation of ongoing negotiations relating to an amendment to 
the supply agreement with Bio E, and Bio E’s dependence on cash collections from the Government of India, which have 
been delayed significantly by the Government of India. 
We have in the past, and may in the future, adjust delivery dates, allow cancellations or give concessions on 
outstanding receivables in certain circumstances to better enable our customers to meet their obligations, which can impact 
the timing or amount of our revenue recognition, cash collections and transfer of control. For example, in August and 
October 2022, we entered into amendments to our Supply Agreement, dated June 29, 2021, with Zhejiang Clover 
Biopharmaceuticals, Inc. and Clover Biopharmaceuticals (Hong Kong) Co., Limited (the "Clover Supply Agreement"), 
which, among other things, modified the scope of the Clover Supply Agreement to reduce certain quantities of CpG 1018 
adjuvant deliverable under the agreement and/or reduce amounts receivable, which we originally intended to deliver in 
accordance with a purchase order previously issued by Clover, and apply prepayments Clover previously made to us as 
payment for portions of pending outstanding purchase orders. In January 2023, we entered into another amendment to the 
Clover Supply Agreement to modify the price per dose of CpG 1018 adjuvant paid by Clover for adjuvant used in finished 
vaccine doses sold through government procurement programs relating to the booster program promoted by the China 
National Health Commission. In addition, in April 2023, we entered into the Bio E Amendment No. 3 and the CEPI-Bio E 
Assignment Agreement, pursuant to which CEPI forgave amounts outstanding relating to the Bio E CEPI Advance 
Payments and assumed our previous rights to collect $47.4 million of Bio E accounts receivable. Among other things, the 
CEPI-Bio E Assignment Agreement resulted in no accounts receivable from Bio E, the derecognition of $47.4 million 
27

CEPI accrual in connection with the Bio E CEPI Advance Payments, and certain additional future payments contingent on 
Bio E’s receipt of payments from the Government of India associated with its CORBEVAX product on or before August 
15, 2025, which may not materialize. 
Moreover, our revenue or operating expenses in one period may be disproportionately higher or lower 
relative to the others due to, among other factors, revenue fluctuations or increases in expenses as we invest in our pipeline. 
We may also incur significant expenses in any given reporting period related to shareholder engagement matters, including, 
without limitation, fees for legal, financial and other professional advisors. Accordingly, comparing our operating results 
on a period-to-period basis may not be meaningful, and investors should not rely on any particular past results as an 
indication of our future performance. If such fluctuations occur or if our operating results deviate from our expectations or 
the expectations of investors or securities analysts, our stock price may be adversely affected. 
We have incurred annual net losses in most years since our inception and could continue to incur significant losses if 
we do not successfully commercialize HEPLISAV-B, launch new products and/or significant sales of our CpG 1018 
adjuvant do not resume.
Prior to January 1, 2021, we had incurred losses in each year since we commenced operations in 1996. 
While we recognized revenue for the years ended December 31, 2021, 2022 and 2024, we recognized a net loss of $6.4 
million for the year ended December 31, 2023. As of December 31, 2024, we had an accumulated deficit of $903.3 million. 
With our investment in the launch and commercialization of HEPLISAV-B in the United States and 
Germany, we have in the past, and could in the future, incur operating losses. Our expenses have increased substantially as 
we maintain our HEPLISAV-B commercial infrastructure, including investments in internal infrastructure to support our 
field sales force and investments in manufacturing and supply chain commitments to maintain commercial supply of 
HEPLISAV-B. Further, we expect to increase research and development costs as we invest in our pipeline. We are already 
advancing a multi-program clinical pipeline leveraging CpG 1018 adjuvant to develop improved vaccines in indications 
with unmet medical needs including a Phase 1/2 clinical trial for shingles and additional clinical and manufacturing 
activities, including a Phase 2 clinical trial expected to initiate in the third quarter of 2025, for plague in collaboration with 
and fully funded by the U.S. Department of Defense (“DoD”). We expect research and development costs to increase 
further if we add additional programs to our pipeline.
Sales of CpG 1018 adjuvant generated significant revenue during the COVID-19 pandemic, but we do not 
currently expect such revenues to continue in the long term, and we did not recognize any CpG 1018 adjuvant revenue in 
the year ended December 31, 2023 nor December 31, 2024. The timing for uptake of our products in the U.S. and abroad 
may further affect costs or losses related to commercialization. Due to the numerous risks and uncertainties associated with 
developing and commercializing vaccine products or other products we may choose to offer in the future, we are unable to 
predict the extent of any future losses or when, if ever, we will become profitable on an annual recurring basis, or, that if 
we are able to reach consistent profitability that it will be sustainable for any period of time. 
Many of our competitors have greater financial resources and expertise than we do. If we are unable to successfully 
compete with existing or potential competitors as a result of these disadvantages, we may be unable to generate 
sufficient, or any, revenues and our business will be harmed.
We compete with pharmaceutical companies, biotechnology companies, academic institutions and research 
organizations, in developing and marketing vaccines and adjuvants. For example, HEPLISAV-B competes in the U.S. with 
established hepatitis B vaccines marketed by Merck, GlaxoSmithKline plc (“GSK”) and VBI Vaccines Inc. ("VBI"), and 
with vaccines from those companies as well as several additional established pharmaceutical companies who market 
abroad. There are also modified schedules of conventional hepatitis B vaccines for limited age ranges that are approved in 
the United States, the European Union and the United Kingdom. Competition in European markets could affect our success 
or the success of our distributor in that market as well. In addition, HEPLISAV-B competes against Twinrix, a bivalent 
vaccine marketed by GSK for protection against hepatitis B and hepatitis A. 
We are also in competition with companies developing vaccines and vaccine adjuvants, generally 
including, among others, GSK, Pfizer, Inc., Sanofi S.A., Merck, Bavarian Nordic A/S, Emergent BioSolutions, Inc., 
Novavax, Inc., Medicago Inc., Valneva, AstraZeneca plc, Moderna, Inc., Johnson & Johnson, VBI, BioNTech SE and 
Curevo Vaccine. We will likely compete with several of these companies in the hepatitis space, shingles space, and other 
spaces occupied by any other product candidates we ultimately choose to advance through our pipeline in the future. 
Products in our clinical pipeline, if approved, will also face competition from competitors who have 
competing clinical programs or already approved products. Existing and potential competitors or other market participants 
may also compete with us for qualified commercial, scientific and management personnel, as well as for technology that 
would otherwise be advantageous to our business. Our success in developing marketable products and achieving a 
28

competitive position will depend, in part, on our ability to attract and retain qualified personnel in the near-term, 
particularly with respect to HEPLISAV-B commercialization. If we do not succeed in attracting new personnel and 
retaining and motivating existing personnel, our operations may suffer and we may be unable to properly manage our 
business, obtain financing as needed, enter into collaborative arrangements, advance or sell our product candidates or 
generate revenues.
We rely on our facility in Düsseldorf, Germany and third parties to supply materials or perform processes necessary to 
manufacture our products and our product candidates. We rely on a limited number of suppliers to produce the 
oligonucleotides we require for development and commercialization. Additionally, we have limited experience in 
manufacturing our products or product candidates in commercial quantities. With respect to HEPLISAV-B, we use a 
pre-filled syringe presentation of the vaccine and our ability to meet future demand will depend on our ability to 
manufacture or have manufactured sufficient supply in this presentation.
We rely on our facility in Düsseldorf and third parties to perform the multiple processes involved in 
manufacturing hepatitis B surface antigen for use in HEPLISAV-B, the combination of the oligonucleotide and the 
antigens, and formulation, fill and finish. We may continue to do the same for any additional products we might add in the 
future through natural internal expansion of our pipeline, or in transactions with an external third-party or parties. The FDA 
approved our pre-filled syringe presentation of HEPLISAV-B in 2018 and we expect such presentation will be the sole 
presentation for HEPLISAV-B going forward. We have limited experience in manufacturing and supplying this 
presentation ourselves, and rely on a contract manufacturer to do so. Our contract manufacturer is the only approved 
provider that we have, and there can be no assurance that we or they can successfully manufacture sufficient quantities of 
pre-filled syringes in compliance with good manufacturing practice ("GMP") in order to meet market demand, whether 
because of problems with our supplier’s own operations, operations of its sub-suppliers, issues with downstream supply 
chains or otherwise. If our contract manufacturer is unable to source components needed to complete fill and finish of our 
pre-filled syringes, we may be required to identify a second source which would have associated costs and regulatory 
requirements. Qualifying a second source could take more than a year to accomplish. If we are unable to do all this, on a 
timely basis or at all, our HEPLISAV-B sales could be materially and adversely impacted.
Historically, we have also relied on a limited number of suppliers to produce oligonucleotides for clinical 
trials and a single supplier to produce (i) our CpG 1018 adjuvant for manufacture of HEPLISAV-B and for sale to our 
collaborators and (ii) our pre-filled syringe presentation. In 2021, we qualified a second supplier to manufacture CpG 1018 
adjuvant for our COVID business. If we are unable to maintain our existing suppliers for CpG 1018 adjuvant, we would 
have to establish an alternate qualified manufacturing capability ourselves, which would result in significant additional 
operating costs and delays in manufacturing HEPLISAV-B, or CpG 1018 adjuvant, and developing and commercializing 
our, and potentially our collaborators’, product candidates. We or other third parties may not be able to produce product at 
a cost, quantity and quality that are available from our current third-party suppliers, or at all.
In countries outside of the U.S., we may not be able to comply with comparable foreign regulations, and 
our manufacturing process may be subject to delays, disruptions or quality control/quality assurance problems. 
Noncompliance with these regulations or other problems with our manufacturing process may limit or disrupt the 
commercialization of our products or our and our collaborators’ product candidates and could result in significant expense.
As we continue to focus on the commercialization of our HEPLISAV-B vaccine and our CpG 1018 adjuvant, we may 
encounter difficulties in managing our commercial growth and expanding our operations successfully.
As our commercial operations expand, we expect that we will also need to manage additional relationships 
with various third parties, including sole source suppliers, distributors, collaboration partners, wholesalers and hospital 
customers. Future growth will impose significant added responsibilities on our organization, in particular on management. 
Our future financial performance and our ability to successfully commercialize our HEPLISAV-B vaccine and CpG 1018 
adjuvant or any new products, and to compete effectively will depend, in part, on our ability to manage any future growth 
effectively. To that end, we may not be able to manage our growth efforts effectively, and hire, train, retain and integrate 
additional management, administrative and sales and marketing personnel, or secure sufficient or timely supply from third 
party service and product providers. Any failure to accomplish any of these activities could prevent us from successfully 
increasing or maintaining the same level of commercial growth as we have seen in the past.
29

If HEPLISAV-B or any products we develop are not accepted by the market or if regulatory authorities limit our 
labeling indications, require labeling content that diminishes market uptake of HEPLISAV-B or any other products we 
develop, or limit our marketing claims, we may be unable to generate significant future revenues, if any.
Even if we obtain regulatory approval for our product candidates, such as our U.S., European Union and 
the United Kingdom approvals of HEPLISAV-B, and are able to commercialize them as we have with HEPLISAV-B, our 
products may not gain market acceptance among physicians, patients, healthcare payors and the medical community.
The degree of market acceptance of HEPLISAV-B and any of our future approved products will depend 
upon a number of factors, including:
•
the indication for which the product is approved and its approved labeling;
•
the presence of other competing approved products;
•
the potential advantages of the product over existing and future treatment methods;
•
the relative convenience and ease of administration of the product;
•
the strength of our sales, marketing and distribution efforts;
•
the price and cost-effectiveness of the product; and
•
third-party coverage and adequate reimbursement and the willingness of patients to pay out-
of-pocket in the absence of sufficient reimbursement by third-party payors.
Market acceptance of vaccines has been negatively impacted in recent years due to increasing vaccine 
skepticism and disinformation. The potential for individuals with anti-vaccine views to hold governmental and other roles 
of influence and for disinformation campaigns to negatively impact potential market acceptance for HEPLISAV-B and any 
of our future approved products may slow our sales growth and weaken our market prospects.
The FDA or other regulatory authorities could limit the labeling indication for which our product 
candidates may be marketed or could otherwise limit marketing efforts for our products. If we are unable to achieve 
approval or successfully market any of our products or product candidates, or marketing efforts are restricted by regulatory 
limits, our ability to generate revenue could be significantly impaired.
As we continue to grow as a commercial organization and enter into supply agreements with customers, those supply 
agreements will have obligations to deliver product that we are in part reliant upon third parties to manufacture on our 
behalf.
As our commercial business begins to expand in connection with commercial sales of HEPLISAV-B or 
CpG 1018 adjuvant, as applicable, the contracts we enter into with our customers will generally carry delivery obligations 
that require us to deliver product in certain quantities and meet certain quality thresholds, among other things, all within 
specified timeframes. If, for any reason, whether due to reliance on third-party manufacturers or otherwise, we are unable 
to deliver timely, compliant products to our customers in quantities that meet our contractual obligations, we could be 
subject to lost revenue, contractual penalties, suits for damages, harm to our reputation or other problems that could 
materially and adversely affect our business. To the extent we add new products in the future, these risks could be 
exacerbated by the added complexity of managing multiple product lines.
We face uncertainty regarding coverage, pricing and reimbursement and the practices of third-party payors, which may 
make it difficult or impossible to sell certain of our products or product candidates on commercially reasonable terms. 
In both domestic and foreign markets, our ability to achieve profitability will depend in part on the 
negotiation of a favorable price, as well as the availability of coverage and adequate reimbursement, from third-party 
payors, in particular for HEPLISAV-B, where existing products are already marketed. In the U.S., pricing for hepatitis B 
vaccines is currently stable and reimbursement is favorable as we believe private and public payors recognize the value of 
prophylaxis in this setting given the high costs of potential morbidity and mortality, and we have achieved coverage with 
most third-party payors. However, there is a risk that some payors may limit coverage to specific products on an approved 
list, also known as a formulary, which might not include HEPLISAV-B. Reimbursement or pricing in jurisdictions outside 
the U.S. may be less favorable. Thus, there can be no assurance that HEPLISAV-B will achieve and sustain stable pricing 
and favorable reimbursement. Our ability to successfully obtain and retain market share and achieve and sustain 
profitability will be significantly dependent on the market’s acceptance of a price for HEPLISAV-B sufficient to achieve 
profitability, and future acceptance of such pricing.  
30

Third-party payors are increasingly challenging the price and cost-effectiveness of medical products and 
services, and pricing, as well as coverage and reimbursement decisions, may not allow our future products to compete 
effectively with existing competitive products. Because we intend to offer products, if approved, that involve new 
technologies, the willingness of third-party payors to reimburse for our products is uncertain. We will have to charge a 
price for HEPLISAV-B or any other products we commercialize that is sufficient to enable us to recover our considerable 
investment in product development and our operating costs. Further, coverage policies and third-party reimbursement rates 
may change at any time. Therefore, even if favorable coverage and reimbursement status is attained, less favorable 
coverage policies and reimbursement rates may be implemented in the future. For example, the newly elected Presidential 
administration may be more skeptical of the safety and efficacy of vaccine products, which could lead to increased 
regulatory scrutiny and more restrictive coverage policies regarding our products and product candidates. Adequate third-
party payor reimbursement may not be available to enable us to maintain price levels sufficient to achieve or maintain 
profitability, and such unavailability could harm our future prospects and reduce our stock price.
The UK and many EU Member States periodically review their reimbursement procedures for medicinal 
products, which could have an adverse impact on reimbursement status. We expect that legislators, policymakers and 
healthcare insurance funds in European countries will continue to propose and implement cost-containing measures, such 
as lower maximum prices, lower or lack of reimbursement coverage and incentives to use cheaper, usually generic, 
products as an alternative to branded products, and/or branded products available through parallel import to keep healthcare 
costs down. Moreover, in order to obtain reimbursement for our products in some European countries, including some EU 
Member States, we may be required to compile additional data comparing the cost-effectiveness of our products to other 
available therapies. This Health Technology Assessment ("HTA") of medicinal products is becoming an increasingly 
common part of the pricing and reimbursement procedures in some EU Member States, including those representing the 
larger markets. The HTA process is the procedure to assess therapeutic, economic and societal impact of a given medicinal 
product in the national healthcare systems of the individual country. The outcome of an HTA will often influence the 
pricing and reimbursement status granted to these medicinal products by the competent authorities of individual EU 
Member States. The extent to which pricing and reimbursement decisions are influenced by the HTA of the specific 
medicinal product currently varies between EU Member States. 
In December 2021, Regulation No 2021/2282 on HTA amending Directive 2011/24/EU, was adopted in the 
EU. This Regulation, which entered into force in January 2022 and applies as of January 12, 2025, is intended to boost 
cooperation among EU Member States in assessing health technologies, including new medicinal products, and providing 
the basis for cooperation at EU level for joint clinical assessments in these areas. The Regulation permits EU Member 
States to use common HTA tools, methodologies, and procedures across the EU, working together in four main areas, 
including joint clinical assessment of the innovative health technologies with the most potential impact for patients, joint 
scientific consultations whereby developers can seek advice from HTA authorities, identification of emerging health 
technologies to identify promising technologies early, and continuing voluntary cooperation in other areas. Individual EU 
Member States continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health 
technologies, and making decisions on pricing and reimbursement. If we are unable to maintain favorable pricing and 
reimbursement status in EU Member States for product candidates that we may successfully develop and for which we may 
obtain regulatory approval, any anticipated revenue from and growth prospects for those products in the EU could be 
negatively affected. In light of the fact that the UK has left the EU, Regulation No 2021/2282 on HTA does not apply in the 
UK. However, the UK Medicines and Healthcare products Regulation Agency (“MHRA”) is working with UK HTA 
bodies and other national organizations, such as the Scottish Medicines Consortium (“SMC”), the National Institute for 
Health and Care Excellence (“NICE”), and the All-Wales Medicines Strategy Group, to introduce new pathways supporting 
innovative approaches to the safe, timely and efficient development of medicinal products. For example, in March 2021, 
the UK introduced the Innovative Licensing and Access Pathway (“ILAP”) which brings together the MHRA, NICE, SMC 
and the All Wales Therapeutics and Toxicology Centre, to accelerate time to market for certain innovative products. The 
ILAP temporarily stopped accepting applications on November 20, 2024, but applications under a relaunched ILAP will 
reopen in March 2025, with changes including improvements to interaction with the National Health Service and an 
amended eligibility and selection criteria. 
Legislators, policymakers and healthcare insurance funds in the EU and the UK may continue to propose 
and implement cost-containing measures to keep healthcare costs down, particularly due to the financial strain that 
COVID-19 placed on national healthcare systems of European countries. These measures could include limitations on the 
prices we would be able to charge for product candidates that we may successfully develop and for which we may obtain 
regulatory approval or the level of reimbursement available for these products from governmental authorities or third-party 
payors. Further, an increasing number of EU and other foreign countries use prices for medicinal products established in 
other countries as “reference prices” to help determine the price of the product in their own territory. Consequently, a 
downward trend in prices of medicinal products in some countries could contribute to similar downward trends elsewhere.

We are subject to ongoing FDA, EU and comparable foreign post-marketing obligations concerning HEPLISAV-B, 
which may result in significant additional expense, and we may be subject to penalties if we fail to comply with 
regulatory requirements or experience unanticipated regulatory issues with HEPLISAV-B.
Our HEPLISAV-B regulatory approval in the United States is subject to certain post-marketing obligations 
and commitments to the FDA. For example, we were required to conduct an observational comparative study of 
HEPLISAV-B to Engerix-B to assess occurrence of acute myocardial infarction (“AMI”). This post-marketing study was 
initiated in August 2018 and concluded in November 2020. While the results of the study, announced in April 2021, 
indicated that there was no increased risk of AMI associated with vaccination with HEPLISAV-B compared to Engerix-B, 
we may be required to conduct further studies on HEPLISAV-B or our other product candidates in the future. Also, we 
received data from the autoimmune portion of our observational study, and the data indicated no association between 
HEPLISAV-B and any of the studied autoimmune diseases. In addition, we conducted a pregnancy registry study to 
provide information on outcomes following pregnancy exposure to HEPLISAV-B and submitted the information to the 
FDA in December 2023. In May 2024, the FDA released us from the post-marketing commitment related to the pregnancy 
registry study. Failure to complete any future post-marketing obligation to the satisfaction of the FDA could result in 
withdrawal of our biologics license application approval, which would have a material adverse effect on our business, 
results of operations, financial condition and prospects. As we advance our pipeline, similar studies may be required for 
other candidates. The results of post-marketing studies may also result in additional warnings or precautions for the 
HEPLISAV-B label or labels of any future products, if authorized, or expose additional safety concerns that may result in 
product liability and withdrawal of a product or products from the market, any of which would have a material adverse 
effect on our business, results of operations, financial condition and prospects.
Similar post-marketing obligations and commitments exist in the European Union and the UK. For 
example, we are required to submit periodic safety update reports to the European Medicines Agency ("EMA") and the 
MHRA and to keep an up-to-date risk management plan that takes into account new information that may lead to a 
significant change in the risk/benefit profile of HEPLISAV-B. In addition, in accordance with our EU marketing 
authorization for HEPLISAV-B, HEPLISAV-B is subject to additional monitoring, meaning that it is monitored more 
intensively than other medicinal products. We may have similar obligations for future products if and when approved. Non-
compliance with European Union or UK requirements regarding safety monitoring or pharmacovigilance can result in 
significant financial penalties.
In addition, the manufacturing processes, labelling, packaging, distribution, adverse event reporting, 
storage, advertising, promotion and recordkeeping for HEPLISAV-B are subject to extensive and ongoing regulatory 
requirements in the United States, the European Union and the UK. These requirements include submissions of safety and 
other post-marketing information and reports, registration, as well as continued compliance with current good 
manufacturing practices (“cGMP”), good clinical practices (“GCP”), International Conference on Harmonization 
guidelines, and good laboratory practices (“GLP”). If we are not able to meet and maintain regulatory compliance for 
HEPLISAV-B or any future product, if authorized, we may lose marketing approval and be required to withdraw our 
product. Withdrawal of our product would have a material adverse effect on our business.
HEPLISAV-B and all of our clinical programs rely on oligonucleotide TLR agonists. In the event of serious adverse 
events relating to TLR agonists, we may be required to reduce the scope of, or discontinue, our operations, or reevaluate 
the viability of strategic alternatives.
Our programs, including HEPLISAV-B, incorporate TLR9 agonist CpG oligonucleotides. If any of our 
product candidates in clinical trials or similar products from competitors or collaborators result in serious adverse events, 
we may be required to delay, discontinue or modify our clinical trials or our clinical trial strategy, or significantly 
reevaluate strategic alternatives. If a safety risk based on mechanism of action or the molecular structure were identified, it 
may hinder our ability to develop our product candidates or enter into potential collaboration or commercial arrangements. 
Rare diseases and a numerical imbalance in cardiac adverse events have been observed in patients in our clinical trials. If 
adverse events are found to relate to our TLR agonist as a whole, we may be required to significantly reduce or discontinue 
our operations.
HEPLISAV-B is subject to regulatory obligations and continued regulatory review, and if we receive regulatory 
approval for our other product candidates, we will be subject to ongoing FDA and foreign regulatory obligations and 
continued regulatory review for such products.
With respect to HEPLISAV-B and our other product candidates in development, we and our third-party 
manufacturers and suppliers are required to comply with applicable cGMP regulations and other international regulatory 
requirements. The regulations require that our products and product candidates be manufactured and records maintained in 
a prescribed manner with respect to manufacturing, testing and quality control/quality assurance activities. Manufacturers 
32

and suppliers of key components and materials must be named in a Biologics License Application (“BLA”) submitted to 
the FDA for any product candidate for which we are seeking FDA approval. Additionally, third-party manufacturers and 
suppliers and any manufacturing facility must undergo a pre-approval inspection before we can obtain marketing 
authorization for any of our product candidates. Even after a manufacturer has been qualified by the FDA, the manufacturer 
must continue to expend time, money and effort in the area of production and quality control to ensure full compliance with 
GMP. Manufacturers are subject to regular, periodic inspections by the FDA following initial approval. Further, to the 
extent that we contract with third parties for the manufacture of our products or product candidates, our ability to control 
third-party compliance with FDA requirements will be limited to contractual remedies and rights of inspection. 
If, as a result of the FDA’s inspections, it determines that the equipment, facilities, laboratories or processes 
do not comply with applicable FDA regulations and conditions of product approval, the FDA may not approve the product 
or may suspend the manufacturing operations. If the manufacturing operations of any of the suppliers for our products or 
product candidates are suspended, we may be unable to generate sufficient quantities of commercial or clinical supplies of 
product to meet market demand, which would harm our business. In addition, if delivery of material from our suppliers is 
interrupted for any reason, we might be unable to ship our approved product for commercial supply or to supply our 
products in development for clinical trials. Significant and costly delays can occur if the qualification of a new supplier is 
required. Similar requirements and procedures apply outside of the United States.
Failure to comply with regulatory requirements could prevent or delay marketing approval or require the 
expenditure of money or other resources to correct. Failure to comply with applicable requirements may also result in 
warning letters, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, 
refusal of the government to renew marketing applications and criminal prosecution, any of which could be harmful to our 
ability to generate revenues and to our stock price.
Regulatory authorities may require more clinical trials for our product candidates than we currently expect or are 
conducting before granting regulatory approval, if regulatory approval is granted at all. Our clinical trials may be 
extended which may lead to substantial delays in the regulatory approval process for our product candidates and may 
impair our ability to generate revenues.
Our registration and commercial timelines depend on further discussions with regulatory authorities and 
requirements and any requests that they may make for additional data or completion of additional clinical trials. Any such 
requirements or requests could:
•
adversely affect our ability to timely and successfully commercialize or market these 
product candidates;
•
result in significant additional costs;
•
potentially diminish any competitive advantages for those products;
•
potentially limit the markets for those products;
•
adversely affect our ability to enter into collaborations or receive milestone payments or 
royalties from potential collaborators;
•
cause us to abandon the development of the affected product candidate; or
•
limit our ability to obtain additional financing on acceptable terms, if at all. 
Clinical trials for our commercial product and product candidates are expensive and time consuming, may take longer 
than we expect or may not be completed at all, and have uncertain outcomes.
Clinical trials, including post-marketing studies, to generate sufficient data to meet FDA and other 
regulatory authority requirements are expensive and time consuming, may take more time to complete than expected, may 
not be completed at all, and may not have favorable outcomes if they are completed. In addition, results from smaller, 
earlier stage clinical studies may not be representative of larger, controlled clinical trials that would be required in order to 
obtain regulatory approval of a product candidate.
Each of our clinical trials requires the investment of substantial planning, expense and time and the timing 
of the commencement, continuation and completion of these clinical trials may be subject to significant delays relating to 
various causes, including scheduling conflicts with participating clinicians and clinical institutions, difficulties in 
identifying and enrolling participants who meet trial eligibility criteria, failure of participants to complete the clinical trial, 
delay or failure to obtain Institutional Review Board (“IRB”), Ethics Committee or regulatory approval to conduct a 
clinical trial at a prospective site, unexpected adverse events and shortages of available vaccine or component supply. 
33

Participant enrollment is a function of many factors, including the size of the relevant population, the proximity of 
participants to clinical sites, the eligibility criteria for the trial, the existence of competing clinical trials and the availability 
of alternative or new treatments. Failure of one or more product candidates to successfully advance through to approval and 
licensure could result in the loss of unrecoverable costs expended and impact our ability to generate future revenue from 
such products, either of which, or both of which, could have an adverse impact on our business.
A key part of our business strategy for products in development is to establish collaborative relationships to help fund or 
manage development and commercialization of our product candidates and research programs. We may not succeed in 
establishing and maintaining collaborative relationships, which may significantly limit our ability to continue to develop 
and commercialize those products and programs, if at all.
We have and may in the future need to establish collaborative relationships to obtain domestic and/or 
international sales, marketing, research, development and distribution capabilities for our products or product candidates 
and our discovery research programs. Failure to obtain a collaborative relationship for those products or product candidates 
and programs in markets outside the U.S. requiring extensive sales efforts may significantly impair the potential for those 
products and programs and we may be required to raise additional capital to continue them. The process of establishing and 
maintaining collaborative relationships is difficult and time-consuming, and even if we establish such relationships, they 
may involve significant uncertainty, including:
•
our partners may seek to renegotiate or terminate their relationships with us due to 
unsatisfactory clinical results, manufacturing issues, a change in business strategy, a change 
of control or other reasons;
•
our perceived shortage of capital resources may impact the willingness of companies to 
collaborate with us; 
•
our contracts for collaborative arrangements are often terminable at will on written notice 
and may otherwise expire or terminate and we may not have alternative funding available;
•
our partners may choose to pursue alternative technologies, including those of our 
competitors;
•
we may have disputes with a partner that could lead to litigation or arbitration;
•
we have limited control over the decisions of our partners and they may change the priority 
of our programs in a manner that would result in termination of the agreement or add 
significant delay in the partnered program;
•
our ability to generate future payments and royalties from our partners depends upon the 
abilities of our partners to establish the safety and efficacy of product candidates, obtain 
regulatory approvals and successfully manufacture and commercialize the products 
developed from product candidates; 
•
we or our partners may fail to properly initiate, maintain or defend our intellectual property 
rights, where applicable, or a party may use our proprietary information in such a way as to 
invite litigation that could jeopardize or potentially invalidate our intellectual property or 
other proprietary rights or expose us to potential liability;
•
our partners may not devote sufficient capital or resources towards our product candidates; 
and
•
our partners may not comply with applicable government regulatory requirements.
Supporting diligence activities conducted by potential collaborators and negotiating the financial and other 
terms of a collaboration agreement are long and complex processes with uncertain results. Despite our efforts, we may be 
unable to secure collaborative arrangements. If we are unable to establish and maintain collaborative relationships on 
acceptable terms or to successfully transition terminated collaborative agreements, we may have to delay or discontinue 
further development of one or more of our product candidates, undertake development and commercialization activities at 
our own expense or find alternative sources of capital.
Even when we are successful in entering into collaboration agreements, collaborations can involve greater 
uncertainty for us, as we have less control over certain aspects of our collaborative programs than we do over our solely-
owned development and commercialization programs, and the financial terms upon which collaborators are willing to enter 
into such an arrangement cannot be certain. If any collaborator fails to fulfill its responsibilities in a timely manner, or at 
all, our research, clinical development, manufacturing or commercialization efforts pursuant to that collaboration could be 
34

delayed or terminated, or it may be necessary for us to assume responsibility for expenses or activities that would otherwise 
have been the responsibility of our collaborator.
For example, we are working to develop our CpG 1018 adjuvant as a premier vaccine adjuvant through 
research collaborations, partnerships and supply arrangements. Current relationships and efforts are focused on adjuvanted 
vaccines for COVID-19, shingles and plague. For some of these relationships, our collaborators have primary 
responsibility for the development, conduct of clinical trials, and for seeking and obtaining regulatory approval of potential 
vaccines containing our adjuvant. We have limited or no control over our collaborators’ decisions, including the amount 
and timing of resources that any of these collaborators will dedicate to such activities. In circumstances where our 
collaborators do not purchase as much adjuvant as we anticipate or they delay placing orders or taking certain deliveries, 
there can be a negative impact on our revenue recognition. If a collaborator fails to conduct collaborative activities 
successfully, the development and commercialization of a vaccine could be delayed or may not occur at all. Lastly, the 
ability of our collaborators to deliver, sell and collect on receivables is not guaranteed and this could, in turn, impact our 
own ability to collect receivables. 
Until we are able to generate significant revenues or achieve profitability through product sales on a consistent basis, 
we may require substantial additional capital to finance our operations. 
As of December 31, 2024, we had $713.8 million in cash and cash equivalents, and marketable securities. 
Prior to January 1, 2021, we incurred net losses in each year since our inception. While we recognized revenue for the 
years ended December 31, 2021, 2022 and 2024, we recognized a net loss of $6.4 million for the year ended December 31, 
2023. As of December 31, 2024, we had an accumulated deficit of $903.3 million. We expect to continue to incur 
substantial expenses as we continue to invest in the commercialization and development of HEPLISAV-B and our CpG 
1018 adjuvant, clinical trials for our pipeline candidates, and other development. If we cannot generate a sufficient amount 
of revenue from product sales, we may need to finance our operations through strategic alliance and licensing arrangements 
and/or future public or private debt and equity financings. Raising additional funds through the issuance of equity or debt 
securities could result in dilution to our existing stockholders, increased fixed payment obligations, or both. In addition, our 
2.50% convertible senior notes due 2026 (“Convertible Notes”) and other securities we issue in the future may have rights 
senior to those of our common stock and could include covenants that restrict our operations.
Our ability to raise additional capital in the equity and debt markets, should we choose to do so, is 
dependent on a number of factors, including, but not limited to, the market demand for our common stock, which itself is 
subject to a number of development and business risks and uncertainties, our creditworthiness and the uncertainty that we 
would be able to raise such additional capital at a price or on terms that are favorable to us. In addition, our ability to raise 
additional funds may be adversely impacted by deteriorating global economic conditions and disruptions to and volatility 
in the credit and financial markets in the United States and worldwide. Adequate financing may not be available to us on 
acceptable terms, or at all. If adequate funds are not available when needed, we may need to significantly reduce our 
operations while we seek strategic alternatives, which could have an adverse impact on our ability to achieve our intended 
business objectives and the value of our stock. 
As we plan for the broader commercialization of our HEPLISAV-B vaccine and for the requisite capacity to 
manufacture our CpG 1018 adjuvant, our financial commitments for manufacturing and supply capacity might outpace 
actual demand for our products.
As we manage our production capabilities for HEPLISAV-B and CpG 1018 adjuvant to support recent 
market share gains and other initiatives, we have been, and in the future could be, required to make significant financial 
commitments at our contract manufacturing organizations (“CMOs”), including minimum purchase commitments and 
prepayments of purchase orders to facilitate the procurement of raw materials and the incurrence of various manufacturing 
costs. Because of minimum or advance purchase commitments and uncertainty about the expected demand for 
HEPLISAV-B or CpG 1018 adjuvant, the financial commitments we make to our CMOs to support manufacturing may not 
be recovered in their entirety, or at all, if our customers do not ultimately purchase from us at expected volumes, or other 
concessions are made by us. Capacity reservation fees are generally not recoverable if we do not use the capacity we have 
reserved as a result of lower than expected demand, or otherwise. Similarly, prepayments of purchase orders may not be 
recoverable if we do not ultimately require the entire volume subject to the applicable purchase order. As a result, we could 
end up making financial commitments that we never recover if demand for HEPLISAV-B or CpG 1018 adjuvant does not 
materialize in the volumes we are expecting or at all. This may require us to record certain charges or write-offs in one or 
more fiscal periods, which in turn could result in significant, unexpected fluctuations in our quarterly and annual operating 
results, and potentially have a material adverse effect on our results of operations, and financial condition.
For example, in August and October 2022, we entered into amendments to the Clover Supply Agreement, 
which, among other things, modified the scope of the Clover Supply Agreement to reduce certain quantities of CpG 1018 
35

adjuvant that we originally intended to deliver in accordance with a purchase order previously issued by Clover. As a result 
of the concessions made in the amendments to the Clover Supply Agreement, prior financial commitments made to certain 
CMOs to manufacture quantities of CpG 1018 adjuvant to fulfill the original Clover purchase order, and reduced demand 
for CpG 1018 adjuvant, we recorded write-offs of $13.9 million of CpG 1018 adjuvant raw materials inventory and $20.4 
million of finished goods inventory during the year ended December 31, 2022. Relating to our Bio E Supply Agreement, 
we entered into an amendment and an assignment agreement in April 2023, pursuant to which (i) CEPI forgave the entirety 
of remaining amounts outstanding relating to the Bio E CEPI Advance Payments for CpG 1018 Materials allocated to Bio 
E and has assumed our previous rights to collect $47.4 million of Bio E accounts receivable, (ii) we collected $14.5 million 
from Bio E, resulting in no accounts receivable balance as of December 31, 2024 and December 31, 2023, and (iii) we 
derecognized a $47.4 million CEPI accrual in connection with the Bio E CEPI Advance Payments. It is possible we may 
have similar write-offs in the future.
We may develop, seek regulatory approval for and market HEPLISAV-B or any other product candidates outside of the 
U.S., the European Union and the United Kingdom, requiring a significant additional commitment of resources. 
Failure to successfully manage our international operations could result in significant unanticipated costs and delays in 
regulatory approval or commercialization of our products or product candidates.
We may seek to introduce HEPLISAV-B, or any other product candidates we may develop, to various 
additional markets in or outside of the U.S., the European Union and the United Kingdom. Developing, seeking regulatory 
approval for and marketing our product candidates in or outside of the U.S., the European Union and the United Kingdom 
in jurisdictions where we don't currently have approval could impose substantial costs, impose burdens on our personnel, 
and divert management’s attention from domestic operations. International operations are subject to risk, including:
•
the difficulty of managing geographically distant operations, including recruiting and 
retaining qualified employees, locating adequate facilities and establishing useful business 
support relationships in the local community;
•
compliance with varying international regulatory requirements, laws and treaties;
•
securing international distribution, marketing and sales capabilities upon favorable terms;
•
adequate protection of our intellectual property rights;
•
obtaining regulatory and pricing approvals at a level sufficient to justify commercialization;
•
legal uncertainties and potential timing delays associated with tariffs, export licenses and 
other trade barriers;
•
foreign tax compliance and diverse tax consequences;
•
the fluctuation of conversion rates between foreign currencies and the U.S. dollar; and
•
regional and geopolitical risks.
In the event that we determine to pursue commercialization of HEPLISAV-B outside the United States, the 
European Union and the United Kingdom, our opportunity will depend upon our receiving regulatory approval, which can 
be costly and time consuming, and there is a risk that one or more regulatory bodies may require that we conduct additional 
clinical trials and/or take other measures which will take time and require that we incur significant additional expense. In 
addition, we may not receive approval in one or more jurisdictions, even if we undertake these efforts.
The results of clinical trials conducted to support regulatory approval in one or more jurisdictions, and any 
failure or delay in obtaining regulatory approval in one or more jurisdictions, may have a negative effect on the regulatory 
approval process in other jurisdictions, including our existing regulatory approval in the United States, the European Union 
and the United Kingdom. If we are unable to successfully manage our international operations, we may incur significant 
unanticipated costs and delays in regulatory approval or commercialization of our products or product candidates, which 
would impair our ability to generate revenues.
We rely on CROs and clinical sites and investigators for our clinical trials. If these third parties do not fulfill their 
contractual obligations or meet expected deadlines, our planned clinical trials may be delayed and we may fail to obtain 
the regulatory approvals necessary to commercialize our product candidates.
We rely on CROs, clinical sites and investigators for our clinical trials. If these third parties do not perform 
their obligations or meet expected deadlines our planned clinical trials may be extended, delayed, modified or terminated. 
While we maintain oversight over our clinical trials and conduct regular reviews of the data, we are dependent on the 
processes and quality control efforts of our third-party contractors to ensure that clinical trials are conducted properly and 
36

that detailed, quality records are maintained to support the results of the clinical trials that they are conducting on our 
behalf. Any extension, delay, modification or termination of our clinical trials or failure to ensure adequate documentation 
and the quality of the results in the clinical trials could delay or otherwise adversely affect our ability to commercialize our 
product candidates and could have a material adverse effect on our business and operations.
As a biopharmaceutical company, we engage CROs to conduct clinical studies, and failure by us or our CROs to 
conduct a clinical study in accordance with GCP standards and other applicable regulatory requirements could result in 
disqualification of the applicable clinical trial from consideration in support of approval of a potential product.
We are responsible for conducting our clinical trials consistent with GCP standards and for oversight of our 
vendors to ensure that they comply with such standards. We depend on medical institutions and CROs to conduct our 
clinical trials in compliance with GCP. To the extent that we or they fail to comply with GCP standards, fail to enroll 
participants for our clinical trials, or are delayed for a significant time in the execution of our trials, including achieving full 
enrollment, we may be affected by increased costs, program delays or both, which may harm our business.
Clinical trials must be conducted in accordance with FDA or other applicable foreign government 
guidelines and are subject to oversight by the FDA, other foreign regulatory authorities, IRBs and the Ethics Committees at 
the medical institutions where the clinical trials are conducted. In addition, clinical trials must be conducted with supplies 
of our product candidates produced under GMP and other requirements in foreign countries and may require large numbers 
of participants.
In addition, we obtain guidance from regulatory authorities on certain aspects of our clinical development 
activities and seek to comply with written guidelines provided by the authorities. These discussions and written guidelines 
are not binding obligations on the part of the regulatory authorities and the regulatory authorities may require additional 
patient data or studies to be conducted. Regulatory authorities may revise or retract previous guidance during the course of 
a clinical trial or after completion of the trial. The authorities may also disqualify a clinical trial from consideration in 
support of approval of a potential product if they deem the guidelines have not been met. The FDA or foreign regulatory 
authorities may determine our clinical trials or other data regarding safety, efficacy or consistency of manufacture or 
compliance with GMP regulations are insufficient for regulatory approval.
The FDA or other foreign regulatory authorities or we ourselves could delay, suspend or halt our clinical 
trials of a product candidate for numerous reasons, including with respect to our product candidates and those of our 
partners in combination agent studies:
•
deficiencies in the trial design;
•
deficiencies in the conduct of the clinical trial including failure to conduct the clinical trial 
in accordance with regulatory requirements or clinical protocols;
•
deficiencies in the clinical trial operations or trial sites resulting in the imposition of a 
clinical hold;
•
a product candidate may have unforeseen adverse side effects, including fatalities, or a 
determination may be made that a clinical trial presents unacceptable health risks;
•
the time required to determine whether a product candidate is effective may be longer than 
expected;
•
fatalities or other adverse events arising during a clinical trial that may not be related to 
clinical trial treatments;
•
a product candidate or combination study may appear to be no more effective than current 
therapies;
•
the quality or stability of a product candidate may fail to conform to acceptable standards;
•
the inability to produce or obtain sufficient quantities of a product candidate to complete the 
trials; 
•
our inability to reach agreement on acceptable terms with prospective CROs and trial sites, 
the terms of which can be subject to extensive negotiation and may vary significantly 
among different CROs and trial sites;
•
our inability to obtain IRB or Ethics Committee approval to conduct a clinical trial at a 
prospective site;
37

•
the inability to obtain regulatory approval to conduct a clinical trial;
•
lack of adequate funding to continue a clinical trial, including the occurrence of unforeseen 
costs due to enrollment delays, requirements to conduct additional trials and studies and 
increased expenses associated with the services of our CROs and other third parties;
•
the inability to recruit and enroll individuals to participate in clinical trials for reasons 
including competition from other clinical trial programs for the same or similar indications; 
or
•
the inability to retain participants who have initiated a clinical trial but may withdraw due to 
side effects from the product, lack of efficacy or personal issues, or who are otherwise 
unavailable for further follow-up.
In addition, we may experience significant setbacks in advanced clinical trials, even after promising results 
in earlier trials, such as unexpected adverse events that occur when our product candidates are given to larger patient 
populations, which often occur in later-stage clinical trials, or less favorable clinical outcomes. Moreover, clinical results 
are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. 
Negative or inconclusive results or adverse medical events, including participant fatalities that may be 
attributable to our product candidates, during a clinical trial may necessitate that it be redesigned, repeated or terminated. 
Further, some of our clinical trials may be overseen by a Data Safety Monitoring Board (“DSMB”), and the DSMB may 
determine to delay or suspend one or more of these trials due to safety or futility findings based on events occurring during 
a clinical trial. Any such delay, suspension, termination or request to repeat or redesign a trial could increase our costs and 
prevent or significantly delay our ability to commercialize our product candidates. Even if we complete all such activities 
without issue, final results may not actually support approval of a particular product candidate.
Our ability to use our net operating loss carryforwards and other tax attributes may be limited.
We have incurred significant net operating losses ("NOLs") during our history, and despite prior 
profitability, may not be able to achieve sustained profitability over the long term. Unused U.S. federal NOLs for taxable 
years beginning before January 1, 2018 may be carried forward to offset future taxable income, if any, until such unused 
NOLs expire. Under legislation enacted in 2017, as modified by legislation enacted in 2020, U.S. federal NOLs incurred in 
taxable years beginning after December 31, 2017 can be carried forward indefinitely, but the deductibility of such U.S. 
federal NOLs in taxable years beginning after December 31, 2020 is limited to 80% of taxable income. It is uncertain if and 
to what extent various states will conform to the aforementioned U.S. tax law provisions.
As of December 31, 2024, we had U.S. federal and state NOL carryforwards of $293.5 million and $262.9 
million, respectively. Of the $293.5 million U.S. federal NOL carryforwards, $293.1 million may be carried forward 
indefinitely with utilization limited to 80% of taxable income, and the remainder will begin to expire in 2025. The state 
NOL carryforwards will begin to expire in 2025.
In addition, under Section 382 of the Internal Revenue Code of 1986, as amended, and corresponding 
provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as one or more 
stockholders or groups of stockholders who own at least 5% of our stock increasing their ownership by more than 50 
percentage points over their lowest ownership percentage within a rolling three-year period, the corporation’s ability to use 
its pre-change NOL carryforwards to offset its post-change income or taxes may be limited. We have experienced 
ownership changes as a result of shifts in our stock ownership in the past, and in the future it is possible that we may be 
deemed to have experienced additional ownership changes as a result of shifts in our stock ownership, some of which may 
be outside of our control. This could limit the amount of NOLs that we can utilize annually to offset future taxable income 
or tax liabilities. Subsequent ownership changes and changes to the U.S. tax rules in respect of the utilization of NOLs may 
further affect the limitation in future years. In addition, at the state level, there may be periods during which the use of 
NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. 
Tax law changes could adversely affect our business and financial condition. 
New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any 
time, which could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, 
rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, legislation 
informally titled the Tax Cuts and Jobs Act of 2017, the 2020 Coronavirus Aid, Relief, and Economic Security Act, and the 
2022 Inflation Reduction Act enacted many significant changes to the U.S. tax laws. Future guidance from the Internal 
Revenue Service and other tax authorities with respect to such legislation may affect us, and certain aspects of the 
38

foregoing tax legislation could be repealed or modified in future legislation. In addition, it is uncertain if and to what extent 
various states will conform to such legislation or any newly enacted federal tax legislation. Changes in corporate tax rates, 
the realization of net deferred tax assets relating to our operations, the taxation of foreign earnings, and the deductibility of 
expenses under past or future reform legislation could have a material impact on the value of our deferred tax assets, could 
result in significant one-time charges, and could increase our future U.S. tax expense. 
We and the third parties supporting our operations are subject to stringent and evolving U.S. and foreign laws, 
regulations, and rules, contractual obligations, industry standards, policies and other obligations related to data privacy 
and security. Our actual or perceived failure to comply with such obligations (or by the third parties supporting our 
operations) could lead to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business 
operations; reputational harm; loss of revenue or profits; loss of customers or sales; and other adverse business 
consequences. 
In the ordinary course of business, we process personal data and other sensitive information, including our 
proprietary and confidential business data, trade secrets, intellectual property, data we may collect about trial participants in 
connection with clinical trials, and other sensitive data. Our data processing activities subject us to numerous data privacy 
and security obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and 
security policies, contracts, and other obligations that govern the processing of personal data by us and on our behalf. 
In the United States, federal, state, and local governments have enacted numerous data privacy and security 
laws, including data breach notification laws, personal data privacy laws, consumer protection laws (e.g., Section 5 of the 
Federal Trade Commission Act), and other similar laws (e.g., wiretapping laws). In the past few years, numerous U.S. 
states—including California, Virginia, Colorado, Connecticut, and Utah—have enacted comprehensive privacy laws that 
impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and affording 
residents with certain rights concerning their personal data. As applicable, such rights may include the right to access, 
correct, or delete certain personal data, and to opt-out of certain data processing activities, such as targeted advertising, 
profiling, and automated decision-making. The exercise of these rights may impact our business and ability to provide our 
products and services. Certain states also impose stricter requirements for processing certain personal data, including 
sensitive information, such as conducting data privacy impact assessments. These state laws allow for statutory fines for 
noncompliance. For example, the California Consumer Privacy Act of 2018, as amended by the California Privacy Rights 
Act of 2020 (“CPRA”) (collectively, “CCPA”) requires businesses to provide specific disclosures in privacy notices and 
honor requests of California residents to exercise certain privacy rights. The CCPA provides for civil penalties of up to 
$7,500 per intentional violation and allows private litigants affected by certain data breaches to recover significant statutory 
damages. Similar laws are being considered in several other states, as well as at the federal and local levels. These 
developments may further complicate compliance efforts and may increase legal risk and compliance costs for us and the 
third parties upon whom we rely. 
We may be subject to new laws governing the privacy of consumer health data, including reproductive, 
sexual orientation, and gender identity privacy rights. For example, Washington’s My Health My Data Act (“MHMD”) 
broadly defines consumer health data, places restrictions on processing consumer health data (including imposing stringent 
requirements for consents), provides consumers certain rights with respect to their health data, and creates a private right of 
action to allow individuals to sue for violations of the law. Other states are considering and may adopt similar laws. 
California also recently passed a law protecting privacy of abortion-related records and other reproductive healthcare 
services. These laws would also apply to our employees in the respective states.
Outside the United States, an increasing number of laws, regulations, and industry standards may govern  
data privacy and security. For example, the European Union’s General Data Protection Regulation (“EU GDPR”), the 
United Kingdom’s General Data Protection Regulation (“UK GDPR”), Brazil’s General Data Protection Law (Lei Geral de 
Proteção de Dados Pessoais, or “LGPD”) (Law No. 13,709/2018), and China’s Personal Information Protection Law 
(“PIPL”) impose strict requirements for processing personal data. For example, under the EU GDPR, companies may face 
temporary or definitive bans on data processing and other corrective actions; fines of up to 20 million Euros or 4% of 
annual global revenue, whichever is greater; or private litigation related to processing of personal data brought by classes 
of data subjects or consumer protection organizations authorized at law to represent their interests.
Regulators in the United States are also increasingly scrutinizing certain personal data transfers and may 
impose data localization requirements, for example, the Biden Administration’s executive order Preventing Access to 
Americans’ Bulk Sensitive Personal Data and United States Government-Related Data by Countries of Concern. 
Outside the United States, certain jurisdictions have enacted data localization and cross-border data transfer 
laws, which could make it more difficult to transfer information across jurisdictions. In particular, the European Economic 
39

Area ("EEA") and the U.K. have significantly restricted the transfer of personal data to the United States and other 
countries whose privacy and data security laws they believe not to offer an adequate level of protection. Although there are 
currently various mechanisms that may be used to transfer personal data from the EEA and U.K. to the United States in 
compliance with law, such as the EU standard contractual clauses, the U.K.’s International Data Transfer Agreement/
Addendum and the EU-U.S. Data Privacy Framework and the U.K. extension thereto (which allows for transfers to 
relevant U.S.-based organizations who self-certify compliance and participate in the Framework), these mechanisms are 
subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer 
personal data to the United States. If we are unable to implement a legal mechanism to ensure that our transfers of personal 
data from the EEA or the U.K. are lawful, we could face adverse consequences, including increased exposure to regulatory 
actions, substantial fines and penalties and injunctions against processing or transferring personal data, and could be 
required to increase our data processing capabilities in the EEA, the U.K. or elsewhere at significant expense. Restrictions 
on our ability to transfer personal data from the EEA, the U.K. or elsewhere could impact our clinical trial activities in the 
EEA or the U.K. and limit our ability to collaborate with CROs and other third parties.
We are also bound by contractual obligations related to data privacy and security, and our efforts to comply 
with such obligations may not be successful. For example, certain privacy laws, such as the GDPR and the CCPA, require 
our customers to impose specific contractual restrictions on their service providers. We publish privacy policies, marketing 
materials and other statements, such as compliance with certain certifications or self-regulatory principles, regarding data 
privacy and security. If these policies, materials or statements are found to be deficient, lacking in transparency, deceptive, 
unfair or misrepresentative of our practices, we may face adverse consequences, which may include, but are not limited to, 
governmental enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar), litigation 
(including class-related claims) and mass arbitration demands, additional reporting requirements and/or oversight, bans on 
processing personal data, orders to destroy or not use personal data, civil and criminal liability and imprisonment of 
company officials.  In particular, plaintiffs have become increasingly more active in bringing privacy-related claims against 
companies, including class claims and mass arbitration demands. Some of these claims allow for the recovery of statutory 
damages on a per violation basis, and, if viable, carry the potential for monumental statutory damages, depending on the 
volume of data and the number of violations. Any of these events could have a material adverse effect on our reputation, 
business or financial condition, including but not limited to interruptions or stoppages in business operations (including 
clinical trials), inability to process personal data or to operate in certain jurisdictions, limited ability to develop or 
commercialize our products, expenditure of time and resources to defend any claim or inquiry or revision or restructuring 
of our operations.
In addition, privacy advocates and industry groups have proposed, and may propose, standards with which 
we are legally or contractually bound to comply or may become subject to in the future.
Our obligations related to privacy and data security are quickly changing and becoming increasingly 
stringent, creating uncertainty. These obligations may be subject to differing applications and interpretations, which may be 
inconsistent or in conflict among jurisdictions. Preparing for and complying with these obligations requires us to devote 
significant resources. These obligations may also necessitate changes to our information technologies, systems and 
practices and those of third parties upon which we rely. Moreover, despite our efforts, our personnel or third parties upon 
which we rely may fail to comply with such obligations, which could negatively impact our business operations and 
compliance posture. 
For instance, in the European Union, the second Network and Information Security Directive (Directive 
(EU) 2022/2555, “NIS2”) entered into force on 17 January 2023 and had to be transposed into the national law of each 
Member State by 17 October 2024. NIS2 creates a specific legal framework for the resilience and incident response 
capabilities of entities operating in 18 sectors, including the health sector. As a result, companies in scope are obligated to 
maintain robust network and information systems security measures and report any significant incidents that might impact 
their operations. Companies that fail to comply with NIS2 may face significant operational disruptions, legal liabilities, and 
regulatory penalties of a maximum of €10 million or up to 2% of the total worldwide turnover of the preceding financial 
year.
Our employees and other personnel can use generative artificial intelligence (“AI”) technologies, from time 
to time, in certain circumstances to perform portions of their work, and the disclosure and use of personal data in generative 
AI technologies is subject to various privacy laws and other privacy obligations. Governments have passed and are likely to 
pass additional laws regulating generative AI. Our use of this technology could result in additional compliance costs, 
regulatory investigations and actions, and lawsuits. Our use of generative AI could make it more difficult to comply with 
various privacy laws and other privacy obligations in the U.S. and Europe and could negatively affect our ability to protect 
or own certain intellectual property, any or all of which may cause us to incur significant expense, cause reputational 
damage, and otherwise adversely affect our business. 
40

If we fail to comply with the extensive requirements applicable to biopharmaceutical manufacturers and marketers 
under the healthcare fraud and abuse, anticorruption, privacy, transparency and other laws of the jurisdictions in 
which we conduct our business, we may be subject to significant liability.
Our activities, and the activities of our agents, including some contracted third parties, are subject to 
extensive government regulation and oversight both in the U.S. and in foreign jurisdictions. Our interactions with 
physicians and others in a position to prescribe or purchase our products are subject to a legal regime designed to prevent 
healthcare fraud and abuse and off-label promotion. We also are subject to laws pertaining to transparency of transfers of 
value to healthcare providers; privacy and data protection; compliance with industry voluntary compliance guidelines; and 
prohibiting the payment of bribes. Relevant U.S. laws include:
•
the federal Anti-Kickback Statute, which prohibits persons from, among other things, 
knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or 
indirectly, in exchange for or to induce either the referral of an individual for, or the 
purchase, order or recommendation of, any good or service for which payment may be 
made under federal health care programs, such as the Medicare and Medicaid programs;
•
federal false claims laws, including the False Claims Act and Civil Monetary Penalties 
Law, which prohibit individuals or entities from, among other things, knowingly presenting, 
or causing to be presented, claims for payment to the government or its agents that are false 
or fraudulent;
•
the Federal Food, Drug and Cosmetic Act and governing regulations which, among other 
things, prohibit off-label promotion of prescription drugs;
•
the federal Physician Payments Sunshine Act created under the Patient Protection and 
Affordable Care Act of 2010, as amended by the Health Care and Education and 
Reconciliation Act of 2010 (collectively, “ACA”) which requires certain manufacturers of 
drugs, devices, biologics and medical supplies to report annually to the Centers for 
Medicare & Medicaid Services, information related to payments and other transfers of 
value to physicians (defined to include doctors, dentists, optometrists, podiatrists and 
chiropractors), other health care professionals (such as physician assistants and nurse 
practitioners), and teaching hospitals, and ownership and investment interests held by such 
physicians and their immediate family members; 
•
the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which 
created, among other things, new federal criminal statutes that prohibit knowingly and 
willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit 
program, or knowingly and willfully falsifying, concealing or covering up a material fact or 
making any materially false statement, in connection with the delivery of, or payment for, 
healthcare benefits, items or services;
•
HIPAA, as amended by the Health Information Technology for Economic and Clinical 
Health Act, and their implementing regulations, which imposes certain requirements on 
“covered entities,” including certain healthcare providers, health plans, and healthcare 
clearinghouses, and their respective “business associates” that create, receive, maintain or 
transmit individually identifiable health information for or on behalf of a covered entity as 
well as their covered subcontractors relating to the privacy, security, and transmission of 
individually identifiable health information; 
•
the Foreign Corrupt Practices Act, which prohibits the payment of bribes to foreign 
government officials and requires that a company’s books and records accurately reflect our 
transactions; and
•
foreign and state law equivalents of each of the federal laws described above, such as anti-
kickback and false claims laws which may apply to items or services reimbursed by state 
health insurance programs or any third-party payor, including commercial insurers; state 
laws that require pharmaceutical companies to comply with the pharmaceutical industry’s 
voluntary compliance guidelines and the applicable compliance guidance promulgated by 
the federal government; state laws that require drug manufacturers to report information on 
the pricing of certain drugs; state and local laws that require the registration of 
pharmaceutical sales representatives; and state and foreign laws governing the privacy and 
security of health information, many of which differ from each other in significant ways 
and often are not preempted by HIPAA.
41

In the U.S., the Office of Inspector General for the Department of Health and Human Services, the 
Department of Justice, states’ Attorneys General and other governmental authorities actively enforce the laws and 
regulations discussed above. These entities also coordinate extensively with the FDA, using legal theories that connect 
violations of the Federal Food, Drug and Cosmetic Act (such as off-label promotion) to the eventual submission of false 
claims to government healthcare programs. Prosecution of such promotion cases under the False Claims Act provides the 
potential for private parties (qui tam relators, or “whistleblowers”) to initiate cases on behalf of the government and 
provides for significantly higher penalties upon conviction.
In the U.S., pharmaceutical and biotechnology companies have been the target of numerous government 
prosecutions and investigations alleging violations of law, including claims asserting impermissible off-label promotion of 
pharmaceutical products, payments intended to influence the referral of federal or state health care business, submission of 
false claims for government reimbursement, or submission of incorrect pricing information.
Violations of any of the laws described above or any other applicable governmental regulations and other 
similar foreign laws may subject us, our employees or our agents to significant criminal, civil and administrative penalties, 
including fines, civil monetary penalties, exclusion from participation in government health care programs (including, in 
the U.S., Medicare and Medicaid), disgorgement, imprisonment, additional reporting requirements and oversight if we 
become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these 
laws and the restriction or restructuring of our operations, any of which could adversely affect our ability to operate our 
business and our financial results. Additionally, whether or not we have complied with the law, an investigation into 
alleged unlawful conduct may cause us to incur significant expense, cause reputational damage, divert management time 
and attention, and otherwise adversely affect our business. While we have developed and instituted a corporate compliance 
program, we cannot guarantee that we, our employees, our consultants, contractors, or other agents are or will be in 
compliance with all applicable U.S. or foreign laws.
We have applied for, and in some cases have received, grants that, if and when received, may involve pricing or other 
restrictions.
We have applied for, and in some cases have received, grants from various charitable, philanthropic and 
other organizations that, if and when received, may come with certain pricing requirements, global access requirements, 
reporting requirements or other covenants that require us to make the funded product available worldwide and on a 
nondiscriminatory basis. For example, we received such an initial grant from the Bill and Melinda Gates Foundation in 
2020 to help fund the potential scale-up of production of our CpG 1018 adjuvant that may be required in the event the CpG 
1018 adjuvant is included in any approved and commercially available vaccine, whether a COVID-19 vaccine or otherwise. 
Covenants in these types of grants may limit the price we can charge for any funded product and may involve a license to 
use technology we own that is included in the funded products if we do not comply. Such price limitations or licenses, if 
invoked, could serve to limit the prices we charge, or our control over the manufacturing and distribution of grant-funded 
products. Failure to agree to such requirements, may result in us not receiving some or all of the grant.
Enacted or future legislation, including potentially unfavorable pricing regulations or other healthcare reform 
initiatives, may have an adverse effect on our operations and business.
We expect there will continue to be federal and state laws and/or regulations, proposed and implemented, 
that could impact our operations and business. For example, the ACA, among other things, imposes a significant annual fee 
on companies that manufacture or import branded prescription drug products. It also contains substantial provisions 
intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, and impose 
additional health policy reforms, any or all of which may affect our business. There have been executive, legal and political 
challenges and amendments to certain aspects of ACA. For example, on August 16, 2022, the Inflation Reduction Act of 
2022 (“IRA”) was signed into law, which among other things, extends enhanced subsidies for individuals purchasing 
health insurance coverage in ACA marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under 
the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and 
through a newly established manufacturer discount program. It is unclear how any such challenges and additional 
healthcare reform measures by the second Trump administration will impact the ACA and our business. 
Other legislative changes have also been proposed and adopted since the ACA was enacted. For example, 
the Budget Control Act of 2011 resulted in aggregate reductions in Medicare payments to providers of up to two percent 
per fiscal year, starting in 2013 and, due to subsequent legislative amendments to the statute, will remain in effect until 
2032 unless additional Congressional action is taken. Additionally, on March 11, 2021, the American Rescue Plan Act of 
2021 was signed into law, which eliminated the statutory Medicaid drug rebate cap, previously set at 100% of a drug’s 
average manufacturer price, for single source and innovator multiple source drugs, effective January 1, 2024.

Also, there has been heightened governmental scrutiny recently in the U.S. over pharmaceutical pricing 
practices in light of the rising cost of prescription drugs and biologics. For example, the IRA, among other things, (i) 
directs the U.S. Department of Health and Human Services (“HHS”) to negotiate the price of certain biologics covered 
under Medicare that have been on the market for at least 11 years (the “Medicare Drug Price Negotiation Program”), and 
subjects drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or 
less than the negotiated “maximum fair price” under the law, and (ii) imposes rebates under Medicare Part B and Medicare 
Part D to penalize price increases that outpace inflation. These provisions began to take effect progressively in 2023, 
although the Medicare Drug Price Negotiation Program is currently subject to legal challenges. On August 15, 2024, HHS 
announced the agree-upon price of the first ten drugs that were subject to price negotiations, which take effect in January 
2026. On January 17, 2025, HHS selected fifteen additional products covered under Part D for price negotiation in 2025. 
Each year thereafter more Part B and Part D products will become subject to the Medicare Drug Price Negotiation 
Program. Further, on December 7, 2023, an initiative to control the price of prescription drugs through the use of march-in 
rights under the Bayh-Dole Act was announced. On December 8, 2023, the National Institute of Standards and Technology 
published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which 
for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. 
While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.
At the state level, legislatures have increasingly passed legislation and implemented regulations designed to 
control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, and 
restrictions on certain product access. In some cases, such legislation and regulations have been designed to encourage 
importation from other countries and bulk purchasing. For example, on January 5, 2024, the FDA approved Florida’s 
Section 804 Importation Program (SIP) proposal to import certain drugs from Canada for specific state healthcare 
programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be 
subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending 
review by the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products 
covered by those programs.
Many EU Member States periodically review their reimbursement procedures for medicinal products, 
which could have an adverse impact on reimbursement status. We expect that legislators, policymakers and healthcare 
insurance funds in the EU Member States will continue to propose and implement cost-containing measures, such as lower 
maximum prices, lower or lack of reimbursement coverage and incentives to use cheaper, usually generic, products as an 
alternative to branded products, and/or branded products available through parallel import to keep healthcare costs down. 
We cannot predict the initiatives that may be adopted in the future or the effect any such initiatives may 
have on our business. However, in the future, there will likely continue to be additional proposals relating to the reform of 
the U.S. healthcare system, particularly in light of the recent U.S. Presidential and Congressional elections and other 
equivalent foreign systems, some of which could further limit coverage and reimbursement of products, including our 
product candidates. For example, the newly elected Presidential administration may be more skeptical of the safety and 
efficacy of vaccine products, which could lead to increased regulatory scrutiny and more restrictive coverage policies 
regarding our products and product candidates. Any reduction in reimbursement from Medicare or other government 
programs may result in a similar reduction in payments from private payors. The implementation of cost containment 
measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or 
commercialize our products.
In connection with our work with the U.S. Department of Defense ("DoD"), we have become a defense contractor, and 
are therefore subject to additional administrative burdens and control requirements in connection with the maintenance 
of that relationship.
In September 2021, we entered into an agreement with the DoD relating to the conduct of a clinical trial 
and studies in connection with the development of an improved plague vaccine. In July 2023, we entered into a contract 
modification with the DoD to support advancement into a nonhuman primate challenge study, and in December 2024, we 
entered into an agreement with the DoD to support additional Phase 2 clinical and manufacturing activities to be performed 
through the first half of 2027. In connection with this agreement, we became subject to new administrative and control 
requirements, including certain reporting obligations as well as a requirement to develop, implement and maintain an 
International Traffic in Arms Regulations compliance program, among other things. Further, if our efforts result in an 
improved plague vaccine and we enter into a supply agreement for finished plague vaccines with the DoD, we expect that 
such a supply contract would impose additional administrative, control, compliance and other obligations. We have limited 
experience developing and administering such programs. Development and maintenance of such programs can be 
burdensome and costly and there can be no guarantee that we will be able to maintain compliance with all of the terms of 
such an agreement. As a federal government contractor, we also maintain plans to ensure compliance with 
nondiscrimination and regulatory requirements for qualified employees on the basis of gender, race, disability, and veteran 
status. Consequently, we may be subject to executive orders and regulatory changes affecting various aspects of our 
43

operations, including compliance with nondiscrimination plans. Any required elimination or modification of such plans in 
response to new executive orders could pose challenges in hiring or retaining employees, and may lead to other adverse 
operational impacts. Failure to comply with requirements applicable to us as a federal contractor could expose us to 
administrative, civil, or criminal liabilities, including fines, penalties, repayments, or suspension or debarment from 
eligibility for future U.S. government contracts and could have a significant reputational or financial impact on our 
business and on our stock price. 
We face product liability exposure, which, if not covered by insurance, could result in significant financial liability.
While we have not experienced any product liability claims to date, the use of any of our product 
candidates in clinical trials and the sale of any approved products, including HEPLISAV-B, will subject us to potential 
product liability claims and may raise questions about a product’s safety and efficacy. As a result, we could experience a 
delay in our ability to commercialize one or more of our product candidates or reduced sales of any approved product 
candidates. In addition, a product liability claim may exceed the limits of our insurance policies and exhaust our internal 
resources. We have obtained limited clinical trial liability and umbrella insurance coverage for our clinical trials. This 
coverage may not be adequate or may not continue to be available in sufficient amounts, at an acceptable cost, or at all. 
While we have obtained product liability insurance coverage for HEPLISAV-B, there is a risk that this coverage may not 
be adequate or may not continue to be available in sufficient amounts, at an acceptable cost or at all. We also may not be 
able to obtain commercially reasonable product liability insurance for any product approved for marketing in the future. A 
product liability claim, product recalls or other claims, as well as any claims for uninsured liabilities or in excess of insured 
liabilities, would divert our management’s attention from our business and could result in significant financial liability.
Risks Related to our Intellectual Property
If third parties assert that we have infringed their patents or other proprietary rights or challenge our patents or other 
proprietary rights, we may become involved in disputes and litigation that would be costly, time consuming and have a 
negative impact on the commercialization of our current products and delay or prevent development or 
commercialization of our product candidates.
We may be exposed to future litigation or other dispute with third parties based on claims that our products, 
product candidates or proprietary technologies infringe their intellectual property rights, or we may be required to enter into 
litigation to enforce patents issued or licensed to us or to determine the ownership, scope or validity of our or another 
party’s proprietary rights, including a challenge as to the validity and scope of our issued and pending claims. From time to 
time, we have been, and in the future may become, involved in various administrative proceedings related to our 
intellectual property which can cause us to incur certain legal expenses. If we become involved in any litigation and/or 
other administrative proceedings related to our intellectual property or the intellectual property of others, we will incur 
substantial additional expenses and it will divert the efforts of our technical and management personnel.
If we or our collaborators are unsuccessful in defending or prosecuting our issued and pending claims or in 
defending potential claims against our products, for example, as may arise in connection with the commercialization of 
HEPLISAV-B or any similar or other product candidate, we or our collaborators could be required to pay substantial 
damages or be unable to commercialize our product candidates or use our proprietary technologies without a license from 
such third party. A license may require the payment of substantial fees or royalties, require a grant of a cross-license to our 
intellectual property or technologies or may not be available on acceptable terms, if at all. Any of these outcomes could 
require us to change our business strategy and could materially impact our business, operations or financial condition. 
If the combination of patents, trade secrets and contractual provisions that we rely on to protect our intellectual property 
is inadequate, the value of our products or product candidates may decrease, and we may be unable to realize any 
commercial benefit from the development of our products or product candidates.
Our success depends on our ability to:
•
obtain and protect commercially valuable patents or the rights to patents both domestically 
and abroad;
•
operate without infringing upon the proprietary rights of others; and
•
prevent others from successfully challenging or infringing our proprietary rights.
We will be able to protect our proprietary rights from unauthorized use only to the extent that these rights 
are covered by valid and enforceable patents for a commercially sufficient term or are otherwise effectively maintained as 
trade secrets. We try to protect our proprietary rights by filing and prosecuting U.S. and foreign patent applications. 
44

However, in certain cases such protection may be limited, depending in part on existing patents held by third parties, or 
other disclosures which impact patentability, which may only allow us to obtain relatively narrow patent protection, if any 
at all. In the U.S., and worldwide, legal standards relating to the validity and scope of patent claims in the 
biopharmaceutical field can be highly uncertain, are still evolving and involve complex legal and factual questions for 
which important legal principles remain unresolved. Changes in U.S. patent and ex-U.S. patent laws could diminish the 
value of patents in general, thereby impairing us and our collaborators’ ability to protect our products.
Our HEPLISAV-B vaccine and CpG 1018 adjuvant have no composition of matter patent protection in the 
United States or elsewhere. We must therefore rely primarily on the protection afforded by method of use patent claims 
relating to HEPLISAV-B vaccine and the use of CpG 1018 adjuvant in vaccines, and trade secret protection and 
confidentiality and other agreements to protect our interests in proprietary know-how related to HEPLISAV-B vaccine and 
CpG 1018 adjuvant. We have three issued U.S. patents relating to certain uses of HEPLISAV-B that are projected to expire 
in 2032. We have filed patent applications claiming compositions and methods of use of CpG 1018 adjuvant for 
COVID-19 and other vaccines, but we cannot provide any assurances that we will receive an issued patent for any of these 
patent applications or that, if issued, any of these patents will provide adequate protection for any intended use of CpG 
1018 adjuvant in vaccines. In addition, we are or may be subject to co-ownership of the underlying intellectual property 
with our collaborators and, therefore, may not be the sole owner and be in a position to diligently control patent 
prosecution, or enforce our rights. If we are unable to adequately obtain patent protection or enforce our other proprietary 
rights relating to CpG 1018 adjuvant, we may be unable to realize any recurring commercial benefit from the development 
of a vaccine containing CpG 1018 adjuvant, and we may not have the ability to prevent others from developing or 
commercializing a vaccine containing CpG 1018 adjuvant. 
We also rely on trade secret protection and confidentiality and other agreements to protect our interests in 
proprietary know-how related to CpG 1018 adjuvant. If we or our collaborators are unable to adequately obtain, protect or 
enforce our proprietary rights relating to CpG 1018 adjuvant, we may be unable to realize recurring commercial benefit 
from the development of a vaccine containing CpG 1018 adjuvant, and we or our collaborators may not have the ability to 
prevent others from developing or commercializing a vaccine containing the adjuvant. Disputes or litigation may also arise 
with our collaborators (with us and/or with one or more third parties), including disputes over ownership rights to 
intellectual property, know-how or technologies developed with our collaborators. 
Because patent applications in the U.S. and many foreign jurisdictions typically are not published 
until 18 months after filing and publications of discoveries in the scientific literature lag behind actual discoveries, we 
cannot be certain that we were the first to file for protection of the inventions set forth in these patent applications or in our 
issued patents. Further, there could be post-grant proceedings such as inter partes review ("IPR"), post grant review 
("PGR"), reexamination, reissue or opposition which could result in claims in our patents being narrowed or invalidated. 
Our commercial success depends significantly on our ability to operate without infringing patents 
and other proprietary rights of third parties. A number of pharmaceutical companies and biotechnology companies, as well 
as universities and research institutions, may have filed patent applications or may have been granted patents that cover 
inventions similar to the inventions owned by or licensed to us. We may not be able to determine with certainty whether 
patents or patent applications of other parties may materially affect our ability to make, use, offer to sell, or sell any 
products. If another party controls patents or patent applications covering our products, we may not be able to obtain the 
rights we need to those patents or patent applications in order to commercialize our products.  
Litigation may be necessary to enforce patents issued or licensed to us or to determine the scope or 
validity of another party’s proprietary rights. The existence of third-party patent applications and patents could significantly 
reduce the coverage of the patents owned by or licensed to us and limit our ability to obtain meaningful patent protection. 
Litigation or any other proceedings could result in substantial costs to and diversion of effort by us, and an adverse 
outcome in a court or patent office could subject us to significant liabilities, require disputed rights to be licensed from 
other parties, or require us to cease using some of our technology. We may not prevail in these actions or proceedings if 
they arise.
In addition, other parties may duplicate, design around or independently develop similar or 
alternative technologies to ours or our licensors. 
The risks and uncertainties that we face with respect to our patents and other proprietary rights include the 
following:
•
we may not receive an issued patent for any of our patent applications or for any patent 
applications that we may have exclusively licensed, now or in the future;
45

•
the pending patent applications we have filed or to which we have exclusive rights may take 
longer than we expect to result in issued patents;
•
the claims of any patents that are issued may not provide meaningful protection or may not 
be valid or enforceable;
•
we might not be able to develop additional proprietary technologies that are patentable;
•
the patents licensed or issued to us or our collaborators may not provide a competitive 
advantage;
•
patents issued to other parties may limit our intellectual property protection or harm our 
ability to do business;
•
other parties may independently develop similar or alternative technologies or duplicate our 
technologies and commercialize discoveries that we attempt to patent; 
•
other parties may design around technologies we have licensed, patented or developed;
•
pending patent applications or issued patents may be challenged by third parties in litigation 
or other proceedings, such as inter partes reviews, pre- and post-grant oppositions, 
reexaminations, derivation proceedings and post-grant review, in the U.S or abroad;
•
we may be subject to claims that our employees or consultants have used or disclosed trade 
secrets or other proprietary information of their former employers or clients, thus putting 
our intellectual property at risk;
•
our reliance on trade secret protection and confidentiality and other agreements may not be 
sufficient to protect our interests and proprietary know-how related to our products and 
processes; and
•
it may be found that we or our collaborators have not complied with various procedural, 
document submission, fee payment and other requirements imposed by patent offices, and 
our patent protection could be reduced or eliminated.
We also rely on trade secret protection and confidentiality agreements to protect our interests in proprietary 
know-how that may not be directed to what is considered to be patentable subject matter, and for processes for which 
patents are difficult to enforce. We cannot be certain that we will be able to protect our trade secrets or other proprietary 
know-how adequately. Any disclosure of confidential data in the public domain or to third parties could allow our 
competitors to learn our trade secrets. If we are unable to adequately obtain or enforce proprietary rights, we may be unable 
to commercialize or continue to commercialize our products, enter into or maintain collaborations, generate revenues or 
maintain any advantage we may have with respect to existing or potential competitors.
We have in the past, and may in the future, rely on licenses to intellectual property from third parties. Impairment of 
these licenses or our inability to obtain or maintain them could severely harm our business.
Our current or future research and development efforts may depend in part upon our license arrangements 
for certain intellectual property owned by or co-owned with third parties. Our dependence on these licenses could subject 
us to numerous risks, such as disputes regarding the use of the licensed intellectual property and the creation and ownership 
of new discoveries under such license agreements. In addition, these license arrangements could require us to make timely 
payments to maintain our licenses and typically contain diligence or milestone-based termination provisions. Our failure to 
meet any obligations pursuant to such agreements could allow licensors to terminate our agreements or undertake other 
remedies such as converting exclusive to non-exclusive licenses if we are unable to cure or obtain waivers for such failures 
or amend such agreements on terms acceptable to us or at all. In addition, license agreements may be terminated or may 
expire by their terms, and we may not be able to maintain the exclusivity of these licenses or any rights to the underlying 
intellectual property. If we cannot obtain and maintain licenses that are advantageous or necessary to the development or 
the commercialization of our products or product candidates, we may be required to expend significant time and resources 
to develop or license similar technology or to find other alternatives to maintaining the competitive position of our products 
or product candidates. If such alternatives are not available to us in a timely manner or on acceptable terms, we may be 
unable to develop or commercialize certain of our products or product candidates. In the absence of a current license, we 
may be required to redesign our technology so it does not infringe a third-party’s intellectual property (including patents), 
which may not be possible or could require substantial funds and time.
We may be subject to claims that we or our employees or consultants have wrongfully used or disclosed alleged trade 
secrets of our employees’ or consultants’ former employers or their clients. These claims may be costly to defend and if 
46

we do not successfully do so, we may be required to pay monetary damages and may lose valuable intellectual property 
rights or personnel. 
Many of our employees or consultants may have been previously employed in other biopharmaceutical 
companies, including our competitors or potential competitors. Some of these individuals executed proprietary rights, non-
disclosure and non-competition agreements in connection with such previous employment or engagements. Although no 
claims against us are currently pending, we may be subject to claims that these employees or consultants or we have 
inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers or 
clients. Litigation may be necessary to defend against these claims. If we fail in defending such claims, in addition to 
paying monetary damages, we may lose valuable intellectual property rights or personnel. A loss of key research personnel 
or their work product could hamper our ability to develop and ultimately commercialize, or prevent us from developing and 
commercializing, our product candidates, which could severely harm our business. Even if we are successful in defending 
against these claims, litigation could result in substantial costs and be a distraction to management.
We may rely, in some circumstances, on trade secrets and confidentiality agreements to protect our 
technology. Although trade secrets are difficult to protect, wherever possible, we use confidential disclosure agreements to 
protect the proprietary nature of our technology. Our standard practice is to require each of our collaborators, commercial 
partners, employees, consultants, contractors and advisors to enter into an agreement before beginning their employment, 
consulting or advisory relationship with us that in general provides that the individuals must keep confidential and not 
disclose to other parties any of our confidential information developed or learned by the individuals during the course of 
their relationship with us except in limited circumstances. These agreements with employees, consultants and contractors 
also generally provide that we own all inventions conceived by the individuals in the course of rendering their employment 
or services to us. However, there can be no assurance that these agreements will not be breached, that we will have 
adequate remedies for any breach, or that our trade secrets and/or proprietary information will not otherwise become 
known or be independently discovered by competitors. To the extent that our employees, consultants or contractors use 
intellectual property owned by others in their work for us, disputes may also arise as to the rights in related or resulting 
know-how and inventions, which could result in substantial costs which could severely harm our business. 
Obtaining and maintaining our patent protection depends on compliance with various procedural, document 
submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection 
could be reduced or eliminated for non-compliance with these requirements. 
Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/
or applications are due to be paid to the United States Patent and Trademark Office and various governmental patent 
agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We employ 
reputable law firms and other professionals to help us comply, and in many cases an inadvertent lapse can be cured by 
payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which 
non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss 
of patent rights in the relevant jurisdictions, and in such an event, our competitors might be able to enter the market.
We may not be able to protect our intellectual property rights throughout the world.
The biopharmaceutical patent environment outside the U.S. is also uncertain. We may be 
particularly affected by this uncertainty since several of our product candidates or our collaborators’ vaccine candidates 
may initially address market opportunities outside the U.S., where we may only be able to obtain limited patent protection, 
if any at all. For example, while many countries such as the U.S. permit method of use patents or patent claims relating to 
the use of drug products, in some countries the law relating to patentability of such use claims is evolving, or may prohibit 
certain activities, and may be unfavorably interpreted to prevent us from successfully prosecuting some or all of our 
pending patent applications. There are some countries that currently do not allow such method of use patents or patent 
claims, or that significantly limit the types of uses, claims or subject matter that are patentable. 
Patents are of national or regional effect. Filing, prosecuting and defending patents on all of our 
products and product candidates in all countries throughout the world would be prohibitively expensive, and our 
intellectual property rights in some countries outside the U.S. can be less extensive than those in the U.S. In addition, the 
laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the 
U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the 
U.S. or from selling or importing products made using our inventions in and into the U.S. or other jurisdictions. 
Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own 
products and, further, may export otherwise infringing products to territories where we have patent protection, but 
enforcement is not as strong as that in the U.S. These competitor products may compete with our products and product 
47

candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from 
competing. 
Geo-political actions in the U.S. and in foreign countries could increase the uncertainties and costs 
surrounding the prosecution or maintenance of our patent applications or those of any current or future licensors and the 
maintenance, enforcement or defense of our issued patents or those of any current or future licensors. 
Various companies have encountered significant problems in protecting and defending intellectual 
property rights in foreign jurisdictions. The legal systems of many countries do not favor the enforcement of patents and 
other intellectual property protection, particularly those relating to pharmaceuticals, which could make it difficult for us to 
stop the infringement of our patents or marketing of competing products in violation of our proprietary rights. 
Various countries outside the U.S. have compulsory licensing laws under which a patent owner 
may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against 
government agencies or government contractors. As a result, a patent owner may have limited remedies in certain 
circumstances, which could materially diminish the value of such patent. If we are forced to grant a license to third parties 
with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial 
condition, results of operations and prospects may be adversely affected. Accordingly, our efforts to enforce our 
intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the 
intellectual property that we develop or license. 
Further, the standards applied by the USPTO, foreign patent offices and other adjudicating bodies 
in granting and/or adjudicating patents are not always applied uniformly or predictably. As such, we do not know the 
degree of future protection that we will have on our products and product candidates. 
Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in 
general, thereby impairing our ability to protect our products.
Changes in either the patent laws or interpretation of the patent laws in the U.S. or in other 
jurisdictions could increase the uncertainties and costs surrounding the prosecution of patent applications and the 
enforcement or defense of issued patents. In the U.S., numerous recent changes to the patent laws and proposed changes to 
the rules of the USPTO may have a significant impact on our ability to protect our technology and enforce our intellectual 
property rights. 
For example, the America Invents Act, involved significant changes in patent legislation. 
Additionally, the U.S. Supreme Court has ruled on several patent cases in recent years, some of which cases either narrow 
the scope of patent protection available in certain circumstances or weaken the rights of patent owners in certain situations. 
For example, in Europe, a new unitary patent system took effect June 1, 2023, which will 
significantly impact European patents, including those granted before the introduction of such a system. Under the unitary 
patent system, European applications have the option, upon grant of a patent, of becoming a Unitary Patent which will be 
subject to the jurisdiction of the Unitary Patent Court ("UPC"). As the UPC is a new court system, there is no precedent for 
the court, increasing the uncertainty of any litigation. Patents granted before the implementation of the UPC will have the 
option of opting out of the jurisdiction of the UPC and remaining as national patents in the UPC countries. Patents that 
remain under the jurisdiction of the UPC will be potentially vulnerable to a single UPC-based revocation challenge that, if 
successful, could invalidate the patent in all countries who are signatories to the UPC. We cannot predict with certainty the 
long-term effects of any potential changes. 
Risks Related to our Common Stock
Our stock price is subject to volatility, and your investment may suffer a decline in value.
The market prices for securities of biopharmaceutical companies have in the past been, and are likely to 
continue in the future to be, very volatile. The market price of our common stock is subject to substantial volatility 
depending upon many factors, many of which are beyond our control, including:
•
our ability to expand or retain our HEPLISAV-B vaccine market share;
•
impact of COVID-19 or other respiratory or seasonal vaccination initiatives on our 
HEPLISAV-B vaccine, CpG 1018 adjuvant, or other product revenue;
48

•
progress or results of any of our clinical trials or regulatory or manufacturing efforts, in 
particular any announcements regarding the progress or results of our planned trials and 
BLA filing and communications, from the FDA or other regulatory authorities;
•
our ability to receive timely regulatory approval for our product candidates;
•
our ability to establish and maintain collaborations for the development and 
commercialization of our product candidates;
•
our ability to raise additional capital to fund our operations, to the extent needed;
•
technological innovations, new commercial products or drug discovery efforts and 
preclinical and clinical activities by us or our competitors;
•
changes in our intellectual property portfolio or developments or disputes concerning the 
proprietary rights of our products or product candidates;
•
our ability to obtain component materials and successfully enter into manufacturing 
relationships for our products or product candidates or establish manufacturing capacity on 
our own;
•
our ability to establish and maintain licensing agreements for intellectual property necessary 
for the development of our product candidates;
•
changes in government regulations, general economic conditions or industry 
announcements;
•
changes in the structure of healthcare payment systems;
•
issuance of new or changed securities analysts’ reports or recommendations;
•
accumulations of our common stock or other public actions by our shareholders and related 
market or investor perceptions and expectations, some of which may be speculative or short 
term in nature;
•
actual or anticipated fluctuations in our quarterly financial and operating results; 
•
the volume of trading in our common stock;
•
investor perceptions or negative announcements by our customers, competitors or suppliers 
regarding their own performance; and
•
industry conditions and general financial, economic and political instability.
The stock markets in general, and the markets for biotechnology and pharmaceutical stocks in particular, 
have historically experienced significant volatility that has often been unrelated or disproportionate to the operating 
performance of particular companies. Changes in the broader macroeconomic condition, including historically high 
inflation, changes in interest rates, government policies, impact of pandemics or endemics and instances of geopolitical 
instability, such as that resulting from the conflicts in the Middle East and Ukraine, can and have caused changes in market 
prices, notwithstanding a lack of fundamental change in the underlying business models or prospects of companies. These 
broad market fluctuations have adversely affected and may in the future adversely affect the market price of our common 
stock, regardless of our actual operating performance.
One or more of these factors could cause a substantial decline in the price of our common stock. In 
addition, securities class action and shareholder derivative litigation have often been brought against a company following 
a decline in the market price of its securities. We have in the past been, and we may in the future be, the target of such 
litigation. Securities and shareholder derivative litigation could result in substantial costs, and divert management’s 
attention and resources, which could harm our business, operating results and financial condition.
Future sales of our common stock or the perception that such sales may occur in the public market could cause our 
stock price to fall.
Sales of a substantial number of shares of our common stock in the public market, or the perception that 
these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital 
through the sale of additional equity securities. 
Under our universal shelf registration statement, we may sell any combination of common stock, preferred 
stock, debt securities and warrants in one or more offerings, including pursuant to our sales agreement with Cowen & 
49

Company, LLC, under which we can offer and sell our common stock from time to time up to aggregate sales proceeds of 
$120.0 million. As of December 31, 2024, we had $120.0 million of our common stock remaining available for future 
issuance under our sales agreement with Cowen & Company, LLC. The sale or issuance of our securities, as well as the 
existence of outstanding options and shares of common stock reserved for issuance under our option and equity incentive 
plans also may adversely affect the terms upon which we are able to obtain additional capital through the sale of equity 
securities.
There can be no assurance with respect to the number of shares of our common stock repurchased under the share 
repurchase program or that our share repurchase program will provide the benefits anticipated.
In November 2024, our Board of Directors authorized a share repurchase program to repurchase up to 
$200.0 million of our common stock, subject to market conditions. We can provide no assurance with respect to the 
number of shares of our common stock repurchased under the share repurchase program or that our share repurchase 
program will provide the benefits anticipated, and it may not prove to be the best use of our cash. The program could affect 
the trading price of our stock and increase volatility, and any announcement of a termination of this program may result in 
a decrease in the trading price of our stock. In addition, this program will reduce our cash reserves.
The anti-takeover provisions of our certificate of incorporation, our bylaws, Delaware law and our stockholder rights 
plan may prevent or frustrate a change in control, even if an acquisition would be beneficial to our stockholders, which 
could affect our stock price adversely and prevent attempts by our stockholders to replace or remove our current 
management.
Provisions of our certificate of incorporation and bylaws may delay or prevent a change in control, 
discourage bids at a premium over the market price of our common stock and adversely affect the market price of our 
common stock and the voting or other rights of the holders of our common stock. These provisions include:
•
authorizing our Board of Directors to issue additional preferred stock with voting rights to 
be determined by the Board of Directors;
•
limiting the persons who can call special meetings of stockholders;
•
prohibiting stockholder actions by written consent;
•
a classified Board of Directors pursuant to which our directors are elected for staggered 
three year terms;
•
providing that a supermajority vote of our stockholders is required for amendment to certain 
provisions of our certificate of incorporation and bylaws; and
•
establishing advance notice requirements for nominations for election to our Board of 
Directors or for proposing matters that can be acted on by stockholders at stockholder 
meetings.
Our limited duration stockholder rights plan also may have certain anti-takeover effects. Specifically, the 
rights issued pursuant to the plan will cause substantial dilution to a person or group that acquires beneficial ownership of 
more than a specified percentage of our outstanding common stock without the prior approval of our Board of Directors. 
Although the rights should not interfere with any merger or other business combination approved by the Board of Directors 
since the rights issued may be amended to permit such acquisition, or may be redeemed by us, the rights plan may deter 
certain parties from pursuing strategic transactions involving us, including potential acquisitions. In addition, we remain 
subject to the provisions of the Delaware corporation law that, in general, prohibit any business combination with a 
beneficial owner of 15% or more of our common stock for three years unless the holder’s acquisition of our stock was 
approved in advance by our Board of Directors.
Risks Related to Our Outstanding Convertible Notes
Servicing our Convertible Notes requires a significant amount of cash, and we may not have sufficient cash flow from 
our business to pay our substantial debt.
Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our 
indebtedness, including the $225.5 million in Convertible Notes, depends on our future performance, which is subject to 
economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash 
flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable 
to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt 
or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our 
indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in 
50

any of these activities or engage in these activities on desirable terms, which could result in a default on our debt 
obligations.
We may not have the ability to generate or raise the funds necessary to settle conversions of the Convertible Notes in 
cash or to repurchase the notes for cash upon a fundamental change, and our future debt may contain limitations on 
our ability to pay cash upon conversion or repurchase of the Convertible Notes.
Holders of the Convertible Notes will have the right, subject to certain conditions and limited exceptions, to 
require us to repurchase all or a portion of their Convertible Notes upon the occurrence of a fundamental change at a 
fundamental change repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, 
plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, upon 
conversion of the Convertible Notes, unless we elect to deliver solely shares of our common stock to settle such conversion 
(other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of 
the Convertible Notes being converted. Moreover, we will be required to repay the Convertible Notes in cash at their 
maturity unless earlier converted, redeemed or repurchased. However, we may not have enough available cash or be able to 
obtain financing at the time we are required to make repurchases of Convertible Notes surrendered therefore or pay cash 
with respect to Convertible Notes being converted. In addition, our ability to repurchase the Convertible Notes or to pay 
cash upon conversions of the Convertible Notes may be limited by law, by regulatory authority or by agreements governing 
our future indebtedness. Our failure to repurchase Convertible Notes at a time when the repurchase is required by the 
indenture governing the Convertible Notes or to pay any cash payable on future conversions of the Convertible Notes as 
required by the indenture governing the Convertible Notes would constitute a default under the indenture governing the 
Convertible Notes. A default under the indenture governing the Convertible Notes or the occurrence of a fundamental 
change itself could also lead to a default under agreements governing our future indebtedness. Moreover, the occurrence of 
a fundamental change under the indenture governing the Convertible Notes could constitute an event of default under any 
agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any 
applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the 
Convertible Notes or make cash payments upon conversions thereof.
The conditional conversion feature of the Convertible Notes may adversely affect our financial condition and operating 
results.
From January 1 through December 31, 2024, the conditions allowing holders to convert all or any portion 
of their Convertible Notes were not met. In the event the conditional conversion feature of the Convertible Notes is 
triggered, holders of Convertible Notes will be entitled to convert their Convertible Notes at any time during specified 
periods at their option. If one or more holders elect to convert their Convertible Notes, unless we elect to satisfy our 
conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any 
fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, 
which could adversely affect our liquidity. In addition, even if holders do not elect to convert their Convertible Notes, we 
could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 
Convertible Notes as a current rather than long-term liability, which would result in a material reduction of our net working 
capital.
Conversion of the Convertible Notes may dilute the ownership interest of our stockholders or may otherwise depress the 
price of our common stock.
From January 1 through December 31, 2024, the conditions allowing holders to convert all or any portion 
of their Convertible Notes have not been met. In the event the conditional conversion feature of the Convertible Notes is 
triggered, the conversion of some or all of the Convertible Notes to shares of common stock may dilute the ownership 
interests of our stockholders. Upon conversion of the Convertible Notes, we have the option to pay or deliver, as the case 
may be, cash, shares of our common stock, or a combination of cash and shares of our common stock. If we elect to settle 
our conversion obligation in shares of our common stock or a combination of cash and shares of our common stock, any 
sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market 
prices of our common stock. In addition, the existence of the Convertible Notes may encourage short selling by market 
participants because the conversion of the Convertible Notes could be used to satisfy short positions, or anticipated 
conversion of the Convertible Notes into shares of our common stock could depress the price of our common stock.
51

Certain provisions in the indenture governing the Convertible Notes may delay or prevent an otherwise beneficial 
takeover attempt of us.
Certain provisions in the indenture governing the Convertible Notes may make it more difficult or 
expensive for a third party to acquire us. For example, the indenture governing the Convertible Notes will require us, 
subject to certain exceptions, to repurchase the Convertible Notes for cash upon the occurrence of a fundamental change 
and, in certain circumstances, to increase the conversion rate for a holder that converts its Convertible Notes in connection 
with a make-whole fundamental change. A takeover of us may trigger the requirement that we repurchase the Convertible 
Notes and/or increase the conversion rate, which could make it more costly for a potential acquirer to engage in such 
takeover. Such additional costs may have the effect of delaying or preventing a takeover of us that would otherwise be 
beneficial to investors.
The Capped Calls may affect the value of the Convertible Notes and our common stock. 
In connection with the issuance of the Convertible Notes, we have entered into capped call transactions 
with the option counterparties totaling $27.2 million (the "Capped Calls"). The Capped Calls cover, subject to customary 
adjustments under the terms of the Capped Calls, the number of shares of common stock that initially underlie the Capped 
Calls. The Capped Calls are expected to offset the potential dilution to our common stock as a result of any conversion of 
the Convertible Notes, subject to a cap based on the cap price. 
In connection with establishing their initial hedges of the Capped Calls, we have been advised that the 
option counterparties and/or their respective affiliates entered into various derivative transactions with respect to our 
common stock concurrently with or shortly after the pricing of the Convertible Notes and/or purchased shares of our 
common stock concurrently with or shortly after the pricing of the Convertible Notes. In addition, the option counterparties 
and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with 
respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market 
transactions following the pricing of the Convertible Notes and prior to the maturity of the Convertible Notes (and are 
likely to do so on each exercise date of the Capped Calls, which are expected to occur during the 30 trading day period 
beginning on the 31st scheduled trading day prior to the maturity date of the Convertible Notes, or following any 
termination of any portion of the Capped Calls in connection with any repurchase, redemption or early conversion of the 
Convertible Notes). This activity could also cause or avoid an increase or a decrease in the market price of our common 
stock or the Convertible Notes.
We are subject to counterparty risk with respect to the capped call transactions.
The option counterparties are financial institutions, and we will be subject to the risk that any or all of them 
might default under the Capped Calls. Our exposure to the credit risk of the option counterparties will not be secured by 
any collateral.
If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor 
in those proceedings with a claim equal to our exposure at that time under the Capped Calls with such option counterparty. 
Our exposure will depend on many factors but, generally, an increase in our exposure will be correlated to an increase in 
the market price and in the volatility of our common stock. In addition, upon a default by an option counterparty, we may 
suffer adverse tax consequences and more dilution than we currently anticipate with respect to our common stock. We can 
provide no assurances as to the financial stability or viability of the option counterparties.
General Risk Factors
The loss of key personnel could delay or prevent achieving our objectives. In addition, our continued growth to support 
commercialization may result in difficulties in managing our growth and expanding our operations successfully.
We depend on our senior executive officers, as well as other key scientific personnel. Our commercial and 
business efforts could be adversely affected by the loss of one or more key members of our commercial or management 
staff, including our senior executive officers. We currently have no key person insurance on any of our employees.
As our operations expand, we expect that we will need to manage additional relationships with various 
vendors, partners, suppliers and other third parties. Future growth will impose significant added responsibilities on 
members of management. Our future financial performance and our ability to successfully commercialize HEPLISAV-B, 
or other future products we may attempt to commercialize, and to compete effectively will depend, in part, on our ability to 
manage any future growth effectively. To that end, we must be able to effectively manage our commercialization efforts, 
research efforts and clinical trials and hire, train and integrate additional regulatory, manufacturing, administrative, and 
52

sales and marketing personnel. We may not be able to accomplish these tasks, and our failure to accomplish any of them 
could prevent us from successfully growing and achieving profitability.
Our business operations are vulnerable to interruptions by natural disasters, health epidemics and other catastrophic 
events beyond our control, the occurrence of which could materially harm our manufacturing, distribution, sales, 
business operations and financial results.
Our business operations are subject to interruption by natural disasters and other catastrophic events beyond 
our control, including, but not limited to, earthquakes, hurricanes, fires, droughts, tornadoes, tsunamis, electrical blackouts, 
public health crises and pandemics, war, terrorism, bank failures and geo-political unrest and uncertainties. We have not 
undertaken a systematic analysis of the potential consequences to our business that might result from any such natural 
disaster or other catastrophic event and have limited recovery plans in place. If any of these events occur, our 
manufacturing and supply chain, distribution, sales and marketing efforts and other business operations could be subject to 
business shutdowns or disruptions and financial results could be adversely affected. We cannot presently predict the scope 
and severity of any potential business shutdowns or disruptions resulting from these events, but if we or any of the third 
parties with whom we engage, including the suppliers, contract manufacturers, distributors and other third parties with 
whom we conduct business, were to experience shutdowns or other business disruptions, our ability to conduct our 
business in the manner and on the timelines presently planned could be materially and adversely affected in a number of 
ways, some of which are not predicable.
Our business could be adversely affected by health epidemics in regions where we have manufacturing 
facilities, sales activities or other business operations. For example, outbreaks of epidemic or pandemic diseases, such as 
COVID-19, or the fear of such events, have and could again in the future cause restrictions on supply chains, restrict access 
to workplaces and affect employee health and availability. Furthermore, during the peak of the COVID-19 pandemic there 
was a significantly reduced utilization of all adult vaccines (other than COVID-19 vaccines), including a reduced 
utilization of HEPLISAV-B.
Although we maintain inventories of HEPLISAV-B and its components, our ability and those of our 
contractors and distributors to produce and distribute HEPLISAV-B could be adversely affected. A pandemic or similar 
health challenge could severely impact the U.S. healthcare system, which may have an adverse effect on usage and sales of 
HEPLISAV-B. In addition, any such event could result in widespread global health crisis that could adversely affect global 
economies and financial markets resulting in an economic downturn that could affect the demand for HEPLISAV-B and 
future revenue and operating results and our ability to raise additional capital when needed on acceptable terms, if at all. 
Additionally, our corporate headquarters in Emeryville, California, is located in a seismically active region 
that also is subject to possible electrical shutdowns and wildfires. Because we do not carry earthquake insurance for 
earthquake-related losses and significant recovery time could be required to resume operations, our financial condition and 
operating results could be materially adversely affected in the event of a major earthquake or catastrophic event. We carry 
only limited business interruption insurance that would compensate us for actual losses from interruption of our business 
that may occur, and any losses or damages incurred by us in excess of insured amounts could adversely affect our business 
and operations.
If our information technology systems or those of third parties upon which we rely, or our data are or were 
compromised, we could experience adverse consequences resulting from such compromise, including but not limited to 
regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational 
harm; loss of revenue or profits; and other adverse consequences.
Our business is increasingly dependent on critical, complex and interdependent information technology 
systems, including internet-based systems, to support business processes as well as internal and external communications. 
In addition, our dependence on information technology systems has intensified because many of our critical business 
activities are now being conducted remotely in our remote-first work environment. The size and complexity of our 
computer systems make them potentially vulnerable to breakdown, malicious intrusion and computer viruses that may 
result in the impairment of key business processes.
In addition, our systems, along with those of our customers, suppliers, or third-party service providers 
which operate critical business systems to process sensitive information in a variety of contexts are potentially vulnerable 
to a variety of evolving threats and data security breaches—whether by employees or others—that may expose sensitive 
data to unauthorized persons. Such threats could include, but not be limited to social-engineering attacks (including 
through phishing attacks), online and offline fraud, malicious code (such as viruses and worms), malware (including as a 
result of advanced persistent threat intrusions), denial-of-service attacks, access attacks (such as credential stuffing or 
53

credential harvesting), personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server 
malfunctions, software or hardware failures, loss of data or other information technology assets, adware, 
telecommunications failures, earthquakes, fires, floods, and other similar threats. Such threats are prevalent and continue to 
rise, are increasingly difficult to detect, and come from a variety of sources, including traditional computer “hackers,” 
threat actors, “hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated 
nation states, and nation-state-supported actors. 
Ransomware attacks, including by organized criminal threat actors, nation-states, and nation-state-
supported actors, are becoming increasingly prevalent and severe and can lead to significant interruptions in our operations, 
loss of data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact 
of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or 
regulations prohibiting such payments. Similarly, supply-chain attacks have increased in frequency and severity, and we 
cannot guarantee that third parties and infrastructure in our supply chain or our third-party partners’ supply chains have not 
been compromised or that they do not contain exploitable flaws or bugs that could result in a breach of or disruption to our 
information technology systems (including our products or the third-party information technology systems that support us 
and our goods). 
We rely on third parties to operate critical business systems to process sensitive information in a variety of 
contexts. Our ability to monitor these third parties’ information security practices is limited, and these third parties may not 
have adequate information security measures in place. If our third-party service providers experience a security incident or 
other interruption, we could experience adverse consequences. While we may be entitled to damages if our third-party 
service providers fail to satisfy their privacy or security-related obligations to us, any award may be insufficient to cover 
our damages, or we may be unable to recover such award.
It may be difficult and/or costly to detect, investigate, mitigate, contain, and remediate a security incident. 
Our efforts to do so may not be successful. Actions taken by us or the third parties with whom we work to detect, 
investigate, mitigate, contain, and remediate a security incident could result in outages, data losses, and disruptions of our 
business. Threat actors may also gain access to other networks and systems after a compromise of our networks and 
systems.
The potential liability and associated consequences we could suffer as a result of any such cyber events 
could be catastrophic and result in irreparable harm including (a) the loss of trade secrets or other intellectual property, or 
(b) the public exposure of personally identifiable information (including sensitive personal information) of our employees, 
collaborators, clinical trial patients, and others, (c) extortion and other monetary damages due to malware or business email 
compromise, (d) significant interruptions in our operations, or (e) other significant damages. A data security breach or 
privacy violation that leads to disclosure or modification of or prevents access to patient information, including personally 
identifiable information or protected health information, could harm our reputation, compel us to comply with federal, state 
and/or international data breach notification laws, subject us to mandatory corrective action, require us to verify the 
correctness of database contents and otherwise subject us to liability under laws and regulations that protect personal data, 
including, but not limited to, HIPAA, similar state data protection regulations, and the EU GDPR and UK GDPR, resulting 
in significant penalties; increased costs; loss of revenue; expenses of computer or forensic investigations; material fines and 
penalties; compensatory, special, punitive or statutory damages; litigation; consent orders regarding our privacy and 
security practices; requirements that we provide notices, credit monitoring services and/or credit restoration services or 
other relevant services to impacted individuals; adverse actions against our licenses to do business; or injunctive relief. 
Compliance with these and any other applicable privacy and data security laws and regulations is a rigorous 
and time-intensive process, and we may be required to put in place additional mechanisms ensuring compliance with the 
new data protection rules. If we fail to comply with any such laws or regulations, we may face significant fines and 
penalties that could adversely affect our business, financial condition and results of operations. Furthermore, the laws are 
not consistent, and compliance in the event of a widespread data breach is costly.
U.S. and equivalent foreign authorities and international authorities warned businesses of increased 
cybersecurity threats from actors seeking to exploit the COVID-19 pandemic. If we are unable to prevent data security 
breaches or privacy violations or implement satisfactory remedial measures, our operations could be disrupted, and we may 
suffer loss of reputation, financial loss and other regulatory penalties because of lost or misappropriated information, 
including sensitive patient data. Moreover, failure to maintain effective internal accounting controls related to data security 
breaches and cybersecurity in general could impact our ability to produce timely and accurate financial statements and 
could subject us to regulatory scrutiny. In addition, these breaches and other inappropriate access can be difficult to detect, 
and any delay in identifying them may lead to increased harm of the type described above. Moreover, the prevalent use of 
mobile devices that access confidential information increases the risk of data security breaches, which could lead to the loss 
of confidential information, trade secrets or other intellectual property. While we have implemented security measures that 
54

are intended to protect our data security and information technology systems, there can be no assurance that these measures 
will be effective. We take steps designed to detect, mitigate, and remediate vulnerabilities in our information systems (such 
as our hardware and/or software, including that of third parties upon which we rely). We may not, however, detect and 
remediate all such vulnerabilities including on a timely basis. Further, we may experience delays in deploying remedial 
measures and patches designed to address identified vulnerabilities.
Such disruptions and breaches of security could have a material adverse effect on our business, financial 
condition and results of operations. Our contracts may not contain limitations of liability, and even where they do, there can 
be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, damages, or claims 
related to our data privacy and security obligations. We cannot be sure that our insurance coverage will be adequate or 
sufficient to protect us from or to mitigate liabilities arising out of our privacy and security practices, that such coverage 
will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.
Adverse developments affecting the financial services industry may have adverse consequences on our business, 
financial condition and stock price.
We regularly maintain cash balances at third-party financial institutions in excess of the FDIC insurance 
limit. Although we assess our banking relationships as we believe necessary or appropriate, our access to funding sources 
in amounts adequate to finance or capitalize our current and projected future business operations could be significantly 
impaired by factors that affect us, the financial institutions with which we have arrangements directly, or the financial 
services industry or economy in general. These factors could involve financial institutions or financial services industry 
companies with which we have financial or business relationships, but could also include factors involving financial 
markets or the financial services industry generally.
ITEM 1B. UNRESOLVED STAFF COMMENTS 
None. 
ITEM 1C. CYBERSECURITY
Risk Management and Strategy
We have implemented and maintain various information security processes designed to identify, assess and 
manage material risks from cybersecurity threats to our critical computer networks, third party hosted services, 
communications systems, hardware and software, and our critical data, including intellectual property, confidential 
information that is proprietary, strategic or competitive in nature, along with personal data and other sensitive information, 
including our trade secrets, data we may collect about trial participants in connection with clinical trials, and other sensitive 
data (“Information Systems and Data”). 
Our Senior Director of IT Infrastructure & Security also functions as our information security officer 
(“ISO”). The ISO (as part of our security function), along with our management committee and broader internal 
cybersecurity, IT infrastructure, and digital technology automation functions, as well as third-party service providers, all 
help identify, assess and manage our cybersecurity threats and risks. Our security function identifies and assesses risks 
from cybersecurity threats by monitoring and evaluating our threat environment using various methods including, for 
example, manual tools, automated tools, subscribing to reports and services that identify cybersecurity threats, analyzing 
reports of threats and actors, conducting scans of the threat environment, evaluating our and our industry’s risk profile, 
evaluating threats reported to us, coordinating with law enforcement concerning threats, responding to proactive outreach 
from CISA and FBI, internal and/or external audits, conducting threat assessments for internal and external threats, third-
party threat assessments, conducting vulnerability assessments to identify vulnerabilities, and use of external intelligence 
feeds.
Depending on the environment, we implement and maintain various technical, physical, and organizational 
measures, processes, standards and policies designed to help manage and mitigate material risks from cybersecurity threats 
to our Information Systems and Data, including, for example: a corporate security incident response plan, a vulnerability 
management policy, a vendor risk management program, incident detection and response processes, IT systems disaster 
recovery procedures, risk assessments, reasonable implementation of security controls in accordance with applicable 
security standards/certifications, encryption of data, network security controls, data segregation, access controls, physical 
security, asset management, tracking and disposal, systems monitoring, employee training, penetration testing, 
cybersecurity insurance, dedicated cybersecurity staff/officer. We also rely on third-party vendor backup/restore, disaster 
recovery and business continuity procedures as stated in the respective SOC 1 and SOC 2 reports if provided by such 
vendors as they pertain to certain of our managed services.
55

Our procedures for assessment and management of material risks from cybersecurity threats are integrated 
into our overall risk management processes. For example, (1) cybersecurity risk is evaluated as a component of our broader 
enterprise risk management program, identified in our risk register and monitored and managed more specifically by our 
Corporate Security Incident Response Team (CSIRT); (2) the security function works with the CSIRT to help prioritize our 
risk management processes and help mitigate cybersecurity threats that we believe are more likely to lead to a possible 
material impact to our business; (3) our ISO evaluates material risks identified from cybersecurity threats against our 
overall business objectives and reports to the audit committee of the board of directors (the "Audit Committee"), which 
reviews and discusses with senior management our overall risk assessment and management. 
We use third-party managed service providers to assist us in identifying, assessing, mitigating and 
managing potential risks from cybersecurity threats. In addition, we engage other advisors from time to time to help 
identify, assess, mitigate and manage new or developing risks in a changing threat landscape. Such ongoing services and 
periodic services include professional services from providers such as legal counsel, threat intelligence service providers, 
cybersecurity consultants, cybersecurity software providers, managed cybersecurity service providers, penetration testing 
firms, dark web monitoring services, and forensic investigators (as needed). 
We use third-party service providers to perform a variety of functions throughout our business, such as 
application service providers, software-as-a-service providers, hosting companies, contract research organizations, contract 
manufacturing organizations, distributors, and other supply chain resources. We have a vendor risk management program 
to help manage cybersecurity risks associated with our use of these providers. This includes risk assessment for each 
vendor, review of security assessments, supplemental security questionnaires (as needed), security assessment calls with 
the vendor's security personnel, and imposition of certain information contractual obligations on the vendor. In addition, 
depending on the nature of the services provided, the sensitivity of the Information Systems and Data at issue, and the 
identity of the provider, our vendor risk management program may involve different levels of assessment designed to help 
identify cybersecurity risks associated with a provider and impose contractual obligations related to cybersecurity on the 
provider.  
For a description of the risks from cybersecurity threats that may materially affect us and how they may do 
so, see our risk factors under Part 1. Item 1A. Risk Factors in this Annual Report on Form 10-K, including “If our 
information technology systems or those of third parties upon which we rely, or our data are or were compromised, we 
could experience adverse consequences resulting from such compromise, including but not limited to regulatory 
investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of 
revenue or profits; and other adverse consequences.”
Governance
Our board of directors addresses our cybersecurity risk management as part of its general oversight 
function. The Audit Committee is responsible for reviewing and discussing with management our cybersecurity risk 
assessment and management processes, including our oversight and the steps we take to monitor and help control risks 
from cybersecurity threats.
Our cybersecurity risk assessment and management processes are implemented and maintained by certain 
of our management, including our ISO, who has over 20 years of experience in information security. Our ISO oversees a 
global team of information security professionals consisting of multiple full time equivalent employees in multiple 
countries.
Our ISO is responsible for hiring appropriate personnel, helping to integrate cybersecurity risk 
considerations into our overall risk management strategy, and communicating key priorities to relevant personnel. Our ISO 
(in coordination with our CSIRT) is also responsible for other functions, including preparing for cybersecurity incidents, 
approving cybersecurity processes, and reviewing security assessments and other security-related reports. Our CSIRT 
reviews, approves and prioritizes information security and cybersecurity policies, projects and initiatives. Executive 
management is responsible for prioritizing initiatives and approving budgets to allocate funding for the foregoing based on 
feedback from the ISO, the CSIRT and the Audit Committee. 
Our cybersecurity incident response processes are designed to escalate certain cybersecurity incidents to 
members of management depending on the circumstances, including our ISO. The ISO works with our CSIRT to help us 
mitigate and remediate cybersecurity threats or incidents of which they are notified. The ISO is responsible for designing 
and promoting general security awareness and training, as well as defining and training relevant participants on our 
incident response processes. Our security and incident response processes include escalation and reporting to the CSIRT, 
56

Disclosure and Risk Committee, senior management and Audit Committee for certain information security incidents, as 
warranted under the circumstances. 
The Audit Committee receives periodic reports from the ISO concerning our significant cybersecurity 
threats and risk, and the processes we have implemented to address them. The Audit Committee also has access to various 
reports, summaries of reports or presentations related to cybersecurity threats, risk and mitigation.

Market Information and Holders
Our common stock is traded on the Nasdaq Global Select Market under the ticker symbol “DVAX.” 
As of February 18, 2025, there were approximately 39 holders of record of our common stock, one of 
which was Cede & Co., a nominee for Depository Trust Company (“DTC”). All of the shares of our common stock held by 
brokerage firms, banks and other financial institutions as nominees for beneficial owners are deposited into participant 
accounts at DTC and are therefore considered to be held of record by Cede & Co. as one stockholder. 
Dividends 
We have never paid any cash dividends on our common stock. We currently expect to retain future earnings 
for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable 
future.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS
The following Management’s Discussion and Analysis of Financial Condition and Results of Operations 
contains forward-looking statements that involve a number of risks and uncertainties. Our actual results could differ 
materially from those indicated by forward-looking statements as a result of various factors, including but not limited to, 
the period for which we estimate our cash resources are sufficient, the availability of additional funds, as well as those set 
forth under “Risk Factors” and those that may be identified from time to time in our reports and registration statements 
filed with the Securities and Exchange Commission. 
The following discussion and analysis is intended to provide an investor with a narrative of our financial 
results and an evaluation of our financial condition and results of operations. The discussion should be read in conjunction 
with the Consolidated Financial Statements and the related notes thereto set forth in “Item 8—Financial Statements and 
Supplementary Data.” 
Overview
We are a commercial stage biopharmaceutical company developing and commercializing innovative 
vaccines to help protect the world against infectious diseases. We are currently focused on our efforts to drive long-term 
shareholder value by maximizing utilization of our HEPLISAV-B® hepatitis B vaccine, expanding our own portfolio of 
innovative vaccine candidates leveraging our proven adjuvant technology, and leveraging our CpG 1018® adjuvant supply 
strategy through both commercial and research collaborations.
Our first marketed product, HEPLISAV-B® [Hepatitis B Vaccine (Recombinant), Adjuvanted], is 
approved in the United States, the European Union and the United Kingdom for the prevention of infection caused by all 
known subtypes of hepatitis B virus in adults aged 18 years and older. In May 2022, we commenced commercial shipments 
of HEPLISAV-B in Germany. 
In April 2022, the CDC's Advisory Committee on Immunization Practices ("ACIP") published its universal 
recommendation for hepatitis B vaccination in adults, advising that all adults aged 19-59 should be vaccinated against 
hepatitis B. We believe this has helped create a significantly expanded total annual market opportunity of approximately 
$900.0 million in the U.S. by 2030, with HEPLISAV-B expected to achieve at least 60% total market share. Additionally, 
we believe the HEPLISAV-B U.S. market opportunity will remain substantial beyond 2030 due to the ongoing penetration 
of the unvaccinated eligible adult population, observed revaccination practices by healthcare providers, and continued gains 
in market share. Our annual revenue has continued to grow significantly since the recommendation was made, as a result of 
our successful efforts to capture a greater share of an expanding market.
We are advancing a pipeline of differentiated product candidates that leverage our CpG 1018 adjuvant to 
develop improved vaccines in indications with unmet medical needs. These programs include vaccine candidates under 
development for shingles and plague and additional vaccine programs in preclinical development. Additionally, we are 
working to advance product candidates utilizing our CpG 1018 adjuvant through discovery efforts and preclinical and 
clinical collaborations with third-party research organizations.
In addition, we manufacture and have supplied in the past, and could supply in the future, our CpG 1018 
adjuvant to a number of global customers, including companies engaged in the development and manufacture of 
COVID-19 vaccines across a variety of vaccine platforms utilizing CpG 1018 adjuvant. While we did not recognize any 
CpG 1018 adjuvant revenue in 2024, we could see new demand in the future if our collaborators work through their 
inventory on hand and need additional supply, or new programs utilizing our adjuvant advance to later stages up to and 
including commercialization. However, long-term demand for CpG 1018 adjuvant supporting COVID-19 or other vaccines 
will be highly dependent on each customer’s ability to commercialize in respective territories and geographies where their 
respective COVID-19 or other vaccines are approved for use.
HEPLISAV-B® Vaccine [Hepatitis B Vaccine (Recombinant), Adjuvanted] 
In Phase 3 trials, HEPLISAV-B demonstrated faster and higher rates of protection with two doses in one 
month compared to another currently approved hepatitis B vaccine, which requires three doses over six months, with a 
similar safety profile. HEPLISAV-B is the only two-dose hepatitis B vaccine for adults approved in the U.S., the European 
Union and the United Kingdom. 
We have worldwide commercial rights to HEPLISAV-B and we market it in the United States and the 
European Union. There are four other vaccines approved for the prevention of hepatitis B in the U.S.: Engerix-B and 
60

Twinrix® from GlaxoSmithKline plc, Recombivax-HB® from Merck & Co and PreHevbrio™ from VBI Vaccines Inc. In 
February 2021, we received Marketing Authorization of HEPLISAV-B from the European Commission for prevention of 
infection caused by all known subtypes of hepatitis B virus in adults aged 18 years and older. In May 2021, we entered into 
a commercialization agreement with Bavarian Nordic for the marketing and distribution of HEPLISAV-B in Germany, and 
in May 2022, we commenced commercial shipments of HEPLISAV-B in Germany. In March 2023, we received marketing 
authorization in the United Kingdom for HEPLISAV-B for the active immunization against hepatitis B virus infection 
caused by all known subtypes of hepatitis B virus in adults aged 18 years and older.
All of our HEPLISAV-B sales in the U.S. are to certain wholesalers and specialty distributors whose 
principal customers include independent hospitals and clinics, integrated delivery networks, public health clinics and 
prisons, the Department of Defense, the Department of Veterans Affairs and retail pharmacies. All of our HEPLISAV-B 
sales in Germany are to one distributor. For the year ended December 31, 2024, HEPLISAV-B product revenue, net was 
$268.4 million.
CpG 1018® Adjuvant Supply for COVID-19 Vaccines 
In January 2021, we entered into an agreement (together with subsequent amendments, the "CEPI 
Agreement") with Coalition for Epidemic Preparedness Innovations (“CEPI”) for the manufacture and reservation of a 
specified quantity of CpG 1018 adjuvant. In May 2021, we entered into the first amendment to the CEPI Agreement. The 
CEPI Agreement enables CEPI to direct the supply of CpG 1018 adjuvant to CEPI partner(s). In exchange for reserving 
CpG 1018 adjuvant, CEPI has agreed to provide advance payments in the form of an interest-free, unsecured, forgivable 
loan (the “Advance Payments”) of up to $176.4 million. 
Through December 31, 2024, we have received Advance Payments totaling approximately $175.0 million 
pursuant to the CEPI Agreement, of which $67.3 million have been repaid and $47.4 million have been forgiven (as 
discussed below). As of December 31, 2024, remaining Advance Payments totaling $60.3 million were reflected in CEPI 
accrual long-term in our consolidated balance sheets, representing the outstanding balance of the Advance Payments 
relating to the Clover Supply Agreement (as defined and discussed below).
In June 2021, we entered into an agreement (together with subsequent amendments, the “Clover Supply 
Agreement”) with Zhejiang Clover Biopharmaceuticals, Inc. and Clover Biopharmaceuticals (Hong Kong) Co., Limited 
(collectively, “Clover”) for the commercial supply of CpG 1018 adjuvant, for use with its protein-based COVID-19 
vaccine candidate, SCB-2019. Under the Clover Supply Agreement, Clover committed to purchase specified quantities of 
CpG 1018 adjuvant, at pre-negotiated prices pursuant to the CEPI Agreement, for use in Clover’s commercialization of 
vaccines containing SCB-2019 and CpG 1018 adjuvant (“Clover Product”). The Clover Supply Agreement also provides 
terms for Clover to order additional quantities of CpG 1018 adjuvant beyond the quantities reserved by CEPI. In 2022 and 
2023, we signed four amendments to the Clover Supply Agreement. The terms and conditions of the Clover Supply 
Agreement were operative through December 31, 2022, and as of December 31, 2022, we had satisfied all delivery 
obligations thereunder.
For CpG 1018 adjuvant reserved for Clover under the CEPI Agreement, Clover is obligated to pay us the 
purchase price upon the earliest of (i) the true-up exercise, (ii) within a specified period after Clover delivers Clover 
Product to a customer, or (iii) Clover’s receipt of payment for Clover Product from a customer.
Approximately $71.3 million relating to future amounts receivable representing a contract asset from 
Clover in connection with the CEPI Agreement are classified as other assets (long term) as of December 31, 2024. The 
classification as long term reflects the timing of expected utilization of CpG 1018 adjuvant for Clover Product expected to 
be sold under the CEPI Agreement. Corresponding Advance Payments of $60.3 million relating to Clover are recorded in 
CEPI accrual long-term in our consolidated balance sheets as of December 31, 2024. These Advance Payments may be 
repaid using cash collected from Clover or forgiven in accordance with the CEPI Agreement. We had no accounts 
receivable balance from Clover as of December 31, 2024 and 2023.
In July 2021, we entered into an agreement (together with subsequent amendments, the “Bio E Supply 
Agreement”) with Biological E. Limited (“Bio E”), for the commercial supply of CpG 1018 adjuvant, for use with Bio E’s 
subunit COVID-19 vaccine candidate, CORBEVAX™. Under the Bio E Supply Agreement, Bio E previously committed 
to purchase specified quantities of CpG 1018 adjuvant at pre-negotiated prices pursuant to the CEPI Agreement, for use in 
Bio E’s commercialization of its CORBEVAX vaccine. The Bio E Supply Agreement also provides terms for Bio E to 
order additional quantities of CpG 1018 adjuvant beyond the quantities reserved by CEPI. In June 2022 and October 2022, 
we entered into two amendments to the Bio E Supply Agreement (the “Bio E Amendment No. 1” and the “Bio E 
Amendment No. 2,” respectively, together the “Bio E Amendments”). The Bio E Amendments primarily established: (i) a 
61

new payment schedule for certain outstanding invoices related to the CEPI product to be the earlier of December 31, 2022, 
or receipt of certain amounts by Bio E from the Government of India in connection with their advance purchase agreement 
for CORBEVAX, and (ii) further modified the scope of the Bio E Supply Agreement, by reducing certain quantities of 
CpG 1018 adjuvant to be delivered. The terms and conditions of the Bio E Supply Agreement were operative through 
December 2022, and as of December 31, 2022, we had satisfied all delivery obligations thereunder.
As of December 31, 2024 and 2023, we had no accounts receivable balance from Bio E. During the first 
quarter of 2023, we recorded an allowance for doubtful accounts of $12.3 million, which was determined by assessing 
changes in Bio E’s credit risk, contemplation of ongoing negotiations relating to Bio E Amendment No. 3 (defined below), 
and Bio E's dependence on cash collections from the Government of India, which have been delayed and significantly 
reduced in connection with the overall reduction in demand for CORBEVAX from the Government of India.
On April 26, 2023, we entered into a third amendment to the Bio E Supply Agreement (the “Bio E 
Amendment No. 3”), and on April 27, 2023, we entered into the waiver and second amendment to the CEPI Agreement by 
and between us and CEPI (the "CEPI-Bio E Assignment Agreement"). Pursuant to the CEPI-Bio E Assignment Agreement, 
CEPI has forgiven the entirety of remaining amounts outstanding relating to a liability for Advance Payments of $47.4 
million (the “Bio E CEPI Advance Payments”) for CpG 1018 Materials allocated to Bio E, and has assumed our previous 
rights to collect $47.4 million of Bio E accounts receivable. Pursuant to the Bio E Amendment No. 3, we collected $14.5 
million from Bio E (including $13.5 million in April 2023 and $1.0 million in August 2023). Accordingly, as of 
December 31, 2024, the CEPI-Bio E Assignment Agreement resulted in: (i) no accounts receivable balance, and (ii) the 
derecognition of $47.4 million CEPI accrual in connection with the Bio E CEPI Advance Payments. The Bio E 
Amendment No. 3 provides for additional future payment of either $5.5 million in the event that Bio E receives at least 
$125.0 million, or $12.3 million in the event that Bio E receives at least $250.0 million in future payments from the 
Government of India associated with its CORBEVAX product on or before August 15, 2025. These additional amounts are 
not considered collectible until the achievement of these future milestones.
See Note 9 - Collaborative Research, Development and License Agreements, in the accompanying notes to 
the consolidated financial statements included in Part II, Item 8, “Financial Statements and Supplementary Data” of this 
Annual Report on Form 10-K.
Convertible Notes
In May 2021, we issued $225.5 million aggregate principal amount of 2.5% convertible senior notes due in 
2026 (the “Convertible Notes”) in a private placement. Total proceeds from the issuance of the Convertible Notes, net of 
debt issuance and offering costs of $5.7 million, were $219.8 million. We used $190.2 million of the net proceeds to repay, 
in full, our outstanding debt and other obligations under our previous loan agreement with CRG Servicing LLC ("Loan 
Agreement") and $27.2 million of the net proceeds to pay the costs of capped call transactions (the "Capped Calls").
In connection with the issuance of the Convertible Notes, we entered into the Capped Calls with one of the 
initial purchasers and other financial institutions, totaling $27.2 million. The Capped Calls have an initial strike price and 
an initial cap price of $10.47 per share and $15.80 per share, respectively, subject to certain adjustments under the terms of 
the Capped Calls. The Capped Calls are freestanding and are considered separately exercisable from the Convertible Notes. 
The Capped Calls are expected to offset the potential dilution to our common stock as a result of any conversion of the 
Convertible Notes, subject to a cap based on the cap price. 
Seasonality
HEPLISAV-B is currently our only revenue-producing product. We believe that HEPLISAV-B product 
revenue is, and will likely continue to be, subject to seasonal variations. Specifically, HEPLISAV-B product revenue has 
generally been, and will likely continue to be, lower in the fourth quarter of our fiscal year compared to the third quarter 
due to holiday schedules and increased focus by healthcare providers on respiratory disease vaccines, including vaccines 
for influenza, COVID-19 and respiratory syncytial virus, during the fall and winter months.
Critical Accounting Estimates
We prepare our consolidated financial statements in accordance with U.S. generally accepted accounting 
principles. In doing so, we are required to make estimates and assumptions. Our critical accounting estimates are those 
estimates that involve a significant level of uncertainty at the time the estimate was made, and changes in them have had or 
are reasonably likely to have a material effect on our financial condition or results of operations. Actual results could differ 
materially from our estimates. We base our estimates on past experience and other assumptions that we believe are 
reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. 
62

See Note 2 - Summary of Significant Accounting Policies, in the accompanying notes to the consolidated 
financial statements included in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report on 
Form 10-K for a summary of our significant accounting policies.
Revenue Recognition
Product Revenue, Net – HEPLISAV-B
We recognize revenue at net sales prices when control of the promised goods is transferred to the customer, 
incorporating estimates such as product returns, chargebacks, discounts, rebates and other fees. While each item is more 
fully described in Note 2 to the Consolidated Financial Statements, the following items reflect the more critical and 
significant estimates used in the preparation of our consolidated financial statements. Our estimates of such items are 
inherently uncertain and if we were to change any of these judgments or estimates, it could cause a material increase or 
decrease in the amount of accounts receivable reserves or revenue reserves accrual that we report in a particular period.
Product Returns: Consistent with industry practice, we offer our customers a limited right of return based 
on the product’s expiration date for product that has been purchased from us. We estimate the amount of our product sales 
that may be returned by our customers and record this estimate as a reduction of revenue in the period the related product 
revenue is recognized. We consider several factors in the estimation of potential product returns including expiration dates 
of the product shipped, the limited product return rights, available information about our customers’ inventory and other 
relevant factors.
Chargebacks: Our customers subsequently resell our product to healthcare providers, pharmacies and 
others. In addition to distribution agreements with our customers, we enter into arrangements with qualified healthcare 
providers that provide for chargebacks and discounts with respect to the purchase of our product. Chargebacks represent 
the estimated obligations resulting from contractual commitments to sell product to qualified healthcare providers at prices 
lower than the list prices charged to customers who directly purchase the product from us. These reserves are established in 
the same period that the related revenue is recognized, resulting in a reduction of product revenue and accounts receivable. 
Chargeback amounts are determined at the time of resale to the qualified healthcare providers by customers, and we issue 
credits for such amounts generally within a few weeks of the customer’s notification to us of the resale. Reserves for 
chargebacks consists of credits that we expect to issue for units that remain in the distribution channel inventories at each 
reporting period end that we expect will be sold to the qualified healthcare providers, and chargebacks for units that our 
customers have sold to the qualified healthcare providers, but for which credits have not been issued.
Inventories 
Inventory is stated at the lower of cost or estimated net realizable value, on a first-in, first-out, or FIFO, 
basis. We primarily use actual costs to determine our cost basis for inventories. Our assessment of market value requires 
the use of estimates regarding the net realizable value of our inventory balances, including an assessment of excess or 
obsolete inventory. We determine excess or obsolete inventory based on multiple factors, including an estimate of the 
future demand for our products, product expiration dates and current sales levels. Our assumptions of future demand for 
our products are inherently uncertain and if we were to change any of these judgments or estimates, it could cause a 
material increase or decrease in the amount of inventory reserves that we report in a particular period.
Recent Accounting Pronouncements 
See Note 2 – Summary of Significant Accounting Policies, in the accompanying notes to the consolidated 
financial statements included in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report on 
Form 10-K for information regarding recent accounting pronouncements that are of significance, or potential significance 
to us.
Results of Operations 
This section of this Form 10-K generally discusses 2024 and 2023 items and year-to-year comparisons 
between 2024 and 2023. Discussions of 2022 items and year-to-year comparisons between 2023 and 2022 that are not 
included in this Form 10-K can be found in "Management's Discussion and Analysis of Financial Condition and Results of 
Operations" in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2023.

Revenues 
Revenues consist of amounts earned from product sales and other revenues. Product revenue, net, consists 
of sales of HEPLISAV-B.
Revenue from HEPLISAV-B product sales is recorded at the net sales price, which includes estimates of 
product returns, chargebacks, discounts, rebates and other fees. Overall, product revenue, net, reflects our best estimates of 
the amount of consideration to which we are entitled based on the terms of the contracts.
Actual amounts of consideration ultimately received may differ from our estimates. If actual results in the 
future vary from our estimates, we will adjust these estimates, which would affect net product revenue and earnings in the 
period such variances become known.

HEPLISAV-B product revenue increased by $55.1 million for the year ended December 31, 2024 
compared to the year ended December 31, 2023. Approximately $40.3 million of the increase was due to higher volume 
driven by continued improvement in market share, particularly in the integrated delivery networks and retail segments, and 
growth in the U.S. hepatitis-B vaccine market related to the Advisory Committee on Immunization Practices ("ACIP") 
universal recommendation. Approximately $14.8 million of the increase was due to higher net sales price.
Other revenue primarily includes revenue from our agreement with the DoD. During the years ended 
December 31, 2024 and 2023, we recognized $8.6 million and $17.6 million of revenue from our agreement with the DoD, 
respectively. The decrease in other revenue was due to the completion of the plague Phase 2 clinical trial during the third 
quarter of 2024, as compared to higher revenue earned in early 2023 in connection with the initiation of Part 2 of the 
plague Phase 2 clinical trial.
Cost of Sales – Product
Cost of sales - product consists primarily of raw materials, certain fill, finish and overhead costs and any 
inventory adjustment charges for HEPLISAV-B.

HEPLISAV-B cost of sales-product decreased by $0.7 million for the year ended December 31, 2024 
compared to the year ended December 31, 2023. The decrease was primarily due to lower per-unit manufacturing costs as a 
result of previous process improvements and lower comparative one-time charges, partially offset by the increase in 
HEPLISAV-B sales volume.

Research and Development Expenses
Research and development expenses are tracked on a program-by-program basis and consist primarily of 
costs incurred for the continued research and development of HEPLISAV-B and CpG 1018 adjuvant, clinical product 
candidates and preclinical studies, which include but are not limited to, compensation and related personnel costs (which 
include benefits, recruitment and travel costs), expenses incurred under agreements with contract research organizations, 
contract manufacturing organizations and service providers that assist in conducting clinical studies and costs associated 
with our preclinical activities, including engineering activities at our manufacturing facility in Düsseldorf related to 
functional improvements of our product and process advances, development activities and regulatory operations. We do not 
allocate stock-based compensation or facility expenses to specific programs because these costs are deployed across 
multiple programs.

(1) In September 2021, we entered into an agreement with the DoD for the development of a recombinant plague vaccine utilizing CpG 1018 adjuvant. 
Under the agreement, we conducted a Phase 2 clinical trial and studies combining our CpG 1018 adjuvant with the DoD's rF1V vaccine. We are 
being fully reimbursed by the DoD for the costs of this study which is recorded in other revenue in our consolidated statements of operations.
Research and development expenses increased by $6.7 million for the year ended December 31, 2024 
compared to the year ended December 31, 2023. 
•
Shingles program costs increased primarily due to increased clinical expenses related to the 
initiation of a Phase 1/2 clinical trial and the completion of patient enrollment in the study 
in the fourth quarter of 2024.
•
Tdap program costs decreased, as we completed the long-term Phase 1 extension study in 
the third quarter of 2024. In connection with the discontinued development of the 
Tdap-1018 program announced in November 2024, we do not expect to incur significant 
research and development expenses for this program in the future.
•
Plague program costs decreased with the completion of the Phase 2 clinical trial in the third 
quarter of 2024, as compared to higher costs incurred in early 2023 due to the initiation of 
Part 2 of the Phase 2 clinical trial.
•
HEPLISAV-B and CpG 1018 adjuvant development costs decreased due to the non-
recurrence of a $1.1 million expense related to an engineering run performed for product 
testing purposes in 2023, partially offset by continued investment in clinical research and 
collaboration.
•
Other program costs increased as we continued to invest in product candidates utilizing our 
CpG 1018 adjuvant through discovery and preclinical efforts, including external 
collaborations.
•
Non-cash stock-based compensation expense increased primarily due to incremental 
headcount to support the advancement of our clinical vaccine programs.
As we continue to progress our clinical-stage pipeline, we expect research and development expenses to 
continue to represent a substantial portion of our expenses and to continue to increase, both in dollar amount and 
proportion of total expense, in future years.

Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of compensation and related costs for our 
commercial support personnel, medical education professionals and personnel in executive and other administrative 
functions, including legal, finance and information technology; costs for outside services such as sales and marketing, post-
marketing studies of HEPLISAV-B, accounting, commercial development, consulting, business development, investor 
relations, insurance, and legal costs that include corporate and patent-related expenses; allocated facility costs; and non-
cash stock-based compensation.
The following is a summary of our selling, general and administrative expenses (in thousands, except for 
percentages):

2024 compared to the year ended December 31, 2023.
•
Compensation and related personnel costs and non-cash stock-based compensation costs 
increased due to continued investments in headcount and personnel across commercial and 
administrative functions to support HEPLISAV-B and pipeline growth.
•
Outside services increased primarily due to continued investments in commercial efforts 
designed to increase HEPLISAV-B market share. 
We expect our selling, general, and administrative expenses to remain consistent in future periods as we 
continue to support the overall growth of our business.
Bad Debt Expense
We did not record bad debt expense during the year ended December 31, 2024. We recorded $12.3 million 
of bad debt expense during the year ended December 31, 2023 in connection with the allowance for doubtful accounts of 
$12.3 million recorded with respect to outstanding accounts receivable from Bio E and relating to CpG 1018 Materials 
delivered under the Bio E Supply Agreement and CEPI Agreement. The allowance for doubtful accounts was determined 
by assessing changes in Bio E’s credit risk, contemplation of ongoing negotiations relating to Bio E Amendment No. 3, and 
Bio E's dependence on cash collections from the Government of India, which have been delayed significantly by the 
Government of India.
Other Income (Expense)
Interest income is reported net of amortization of premiums and discounts on marketable securities and 
includes realized gains on investments. Interest expense includes the stated interest and accretion of discount of our 
Convertible Notes. Sublease income is recognized in connection with our sublease of office and laboratory space.

2024 and 2023, respectively, are primarily comprised of state and foreign income tax expense. Our effective tax rate for the 
years ended December 31, 2024 and 2023 was 11.5% and (46.3)%, respectively, which is primarily comprised of state and 
foreign income tax expense.
Liquidity and Capital Resources
As of December 31, 2024, we had $713.8 million in cash and cash equivalents and marketable securities. 
Since our inception, we have relied primarily on the proceeds from public and private sales of our equity securities, 
borrowings, government grants and revenues from product sales and collaboration agreements to fund our operations. Our 
funds are currently invested in money market funds, U.S. treasuries, U.S. government agency securities and corporate debt 
securities. We currently anticipate that our cash and cash equivalents, and short-term marketable securities as of 
December 31, 2024, and anticipated revenues from HEPLISAV-B will be sufficient to fund our operations for at least the 
next 12 months from the date of this filing and in the longer term.
Advanced payments received from CEPI to reserve a specified quantity of CpG 1018 adjuvant are initially 
accounted for as long-term deferred revenue. When we deliver CpG 1018 adjuvant to CEPI partner(s) or when we receive 
payment from CEPI partner(s), we reclassify the advanced payments from long-term deferred revenue to accrued liabilities. 
As of December 31, 2024 and 2023, we had no CEPI-related net accounts receivable relating to Bio E. CEPI-related 
accruals and contract assets relating to Clover totaled $60.3 million and $71.3 million as of December 31, 2024 and 2023, 
respectively. As of December 31, 2024, the CEPI-related accrual relating to Clover may be repaid using cash to be 
collected from Clover or forgiven in accordance with the CEPI Agreement.
In November 2024, our Board of Directors authorized the Program allowing us to repurchase up to $200.0 
million of our common stock. On November 8, 2024, we entered into an accelerated share repurchase agreement (the "ASR 
Agreement") with Goldman Sachs & Co. LLC ("Goldman") to repurchase an aggregate amount of $100.0 million of our 
common stock. Under the ASR agreement, we made an aggregate upfront payment of $100.0 million to Goldman and 
received an aggregate initial delivery of 6,149,116 shares of our common stock on November 12, 2024, representing 
approximately 80% of the total shares that would be repurchased under the ASR Agreement measured based on the closing 
price of our common stock on November 8, 2024. 
67

The final number of shares that we ultimately repurchased pursuant to the ASR Agreement will be based on 
the average of the daily volume-weighted average price ("VWAP") per share of our common stock during the repurchase 
period, subject to adjustments pursuant to the terms and conditions of the ASR Agreement. The accelerated share 
repurchase terminated in February 2025.
As of December 31, 2024, $100.0 million remained available for future repurchases under the Program. See 
Note 14 - Stockholder's Equity, in the accompanying notes to the consolidated financial statements included in Part II, Item 
8, “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K.
On April 26, 2023, we entered into the Bio E Amendment No. 3, and on April 27, 2023, we entered into the 
CEPI-Bio E Assignment Agreement. Pursuant to the CEPI-Bio E Assignment Agreement, CEPI has forgiven the entirety 
of remaining amounts outstanding relating to the Bio E CEPI Advance Payments for CpG 1018 Materials allocated to Bio 
E and has assumed our previous rights to collect $47.4 million of Bio E accounts receivable. The CEPI-Bio E Assignment 
Agreement resulted in no accounts receivable balance from Bio E. Pursuant to the Bio E Amendment No. 3, we collected 
$13.5 million from Bio E in April 2023 and subsequently collected the remaining $1.0 million in August 2023. The Bio E 
Amendment No. 3 provides for additional future payment of either $5.5 million in the event that Bio E receives at least 
$125.0 million, or $12.3 million in the event that Bio E receives at least $250.0 million in future payments from the 
Government of India associated with its CORBEVAX product on or before August 15, 2025. These additional amounts are 
not considered collectible until the achievement of these future milestones.
As of December 31, 2024, the aggregate principal amount of our Convertible Notes was $225.5 million, 
excluding debt discount of $1.6 million. The Convertible Notes bear interest at a rate of 2.5% per year, payable 
semiannually in arrears on May 15 and November 15 of each year. The Convertible Notes mature on May 15, 2026, unless 
converted, redeemed or repurchased in accordance with their terms prior to such date. See Note 10 – Convertible Notes, in 
the accompanying notes to the consolidated financial statements included in Part II, Item 8, “Financial Statements and 
Supplementary Data” of this Annual Report on Form 10-K.
We entered into an at-the-market Sales Agreement with Cowen and Company, LLC (“Cowen”) on August 
6, 2020 and an amendment to such agreement on August 3, 2023 (the sales agreement as amended, the “ATM 
Agreement”). Under the ATM Agreement, we may offer and sell from time to time, at our sole discretion, shares of our 
common stock having an aggregate offering price of up to $120.0 million through Cowen as our sales agent. We agreed to 
pay Cowen a commission of up to 3% of the gross sales proceeds of any common stock sold through Cowen under the 
ATM Agreement. As of December 31, 2024, we had approximately $120.0 million remaining under the ATM Agreement. 
Prior to January 1, 2021, we incurred net losses in each year since our inception. For the year ended 
December 31, 2024, we recorded a net income of $27.3 million. For the year ended December 31, 2023, we recorded a net 
loss of $6.4 million. We cannot be certain that sales of our products, and the revenue from our other activities will be 
sustainable. Further, we expect to continue to incur substantial expenses as we continue investing in commercialization of 
HEPLISAV-B, advancing our research and development pipeline, and investing in clinical trials and other development. If 
we cannot generate a sufficient amount of revenue from product sales, we will need to finance our operations through 
strategic alliance and licensing arrangements and/or future public or private debt and equity financings. Raising additional 
funds through the issuance of equity or debt securities could result in dilution to our existing stockholders, increased fixed 
interest payment obligations, or both. In addition, these securities may have rights senior to those of our common stock and 
could include covenants that would restrict our operations.
Our ability to raise additional capital in the equity and debt markets, should we choose to do so, is 
dependent on a number of factors, including, but not limited to, the market demand for our common stock, which itself is 
subject to a number of development and business risks and uncertainties, our creditworthiness and the uncertainty that we 
would be able to raise such additional capital at a price or on terms that are favorable to us or at all. In addition, our ability 
to raise additional funds may be adversely impacted by deteriorating global economic conditions and the recent or future 
disruptions to and volatility in the credit and financial markets in the United States and worldwide. Adequate financing 
may not be available to us on acceptable terms, or at all. If adequate funds are not available when needed, we may need to 
significantly reduce our operations while we seek strategic alternatives, which could have an adverse impact on our ability 
to achieve our intended business objectives.
During the year ended December 31, 2024, we generated $66.5 million of cash from our operations, which 
consisted of a net income of $27.3 million, $55.2 million of net adjustments from non-cash items, which included 
depreciation and amortization, amortization of right-of-use assets, inventory write off, sublease termination loss, 
amortization of premiums (accretion of discounts) on marketable securities, stock-based compensation expense, non-cash 
interest expense, and approximately $16.0 million net changes from operating assets and liabilities, which included an 
68

increase  of $19.9 million in inventories primarily related to higher number of batches produced, an increase of $3.1 
million in prepaid assets and other current assets primarily related to interest receivable, prepaid taxes, and prepaid 
insurance, a decrease of $4.4 million in lease liabilities, and an increase of $11.0 million in accrued and other liabilities. By 
comparison, during the year ended December 31, 2023, we generated $100.6 million of cash from our operations, which 
consisted of a net loss of $6.4 million, $46.7 million of net adjustments from non-cash items, which included depreciation 
and amortization, amortization of right-of-use assets, amortization of premiums (accretion of discounts) on marketable 
securities, stock-based compensation expense, non-cash interest expense, bad debt expense, and approximately $61.2 
million net changes from operating assets and liabilities, which included a decrease of $43.3 million in accounts and other 
receivables, net and a increase of $19.8 million in accrued and other liabilities. Overall, cash provided by our operations 
during the year ended December 31, 2024 decreased by $34.1 million compared to the same period in December 31, 2023. 
Net cash provided by operating activities is also impacted by changes in our operating assets and liabilities due to timing of 
cash receipts and expenditures. 
During the year ended December 31, 2024, net cash used in investing activities was $18.0 million 
compared to $153.9 million of cash used in investing activities for the year ended December 31, 2023. Cash used in 
investing activities during the year ended December 31, 2024 included $11.7 million of net purchases of marketable 
securities, compared to $150.8 million of net purchases of marketable securities for the year ended December 31, 2023.
During the year ended December 31, 2024, net cash used in financing activities was $102.0 million 
compared to $1.4 million of cash provided by financing activities for the year ended December 31, 2023. Cash used in 
financing activities for the year ended December 31, 2024 included $100.0 million payment for the repurchase of common 
stock in connection with our ASR Agreement, $9.3 million for the payments of taxes related to net share settlement of 
restricted stock units ("RSUs"), partially offset by proceeds received from the exercise of options and from share purchases 
under our employee stock purchase plan for $7.3 million combined. Cash used in financing activities for the year ended 
December 31, 2023 included $6.5 million for the payments of taxes related to net share settlement of restricted stock units 
("RSUs"), partially offset by proceeds received from the exercise of options and from share purchases under our employee 
stock purchase plan for $7.9 million combined.
Contractual Obligations 
We lease our facilities in Emeryville, California and Düsseldorf, Germany. We lease and sublease certain 
manufacturing and office space with lease terms ranging from 3 to 12 years. These leases require monthly lease payments 
that may be subject to annual increases throughout the lease term. Certain of these leases also include renewal options at 
our election to renew or extend the lease for two successive five-year terms. These optional periods have not been 
considered in the determination of the Right-of-use (“ROU”) assets or lease liabilities associated with these leases as we 
did not consider the exercise of these options to be reasonably certain.
In December 2024, we entered into the first amendment of our headquarters office space lease (the "lease 
amendment") located at 2100 Powell Street, Emeryville, California, The lease amendment extends the term of the original 
lease by 36 months to July 31, 2028. The base rent is approximately $0.3 million for the first 12 months, including a four-
month abatement, and scheduled annual 3% increases. The lease includes a renewal option.
We also sublease one of our leased premises to a third party. Rent is subject to scheduled annual increases 
and the subtenant is responsible for certain operating expenses and taxes throughout the life of the sublease. The sublease 
term expires on March 31, 2031, unless earlier terminated, concurrent with the term of our lease. The subtenant has no 
option to extend the sublease term. Sublease income was $5.0 million, $7.6 million and $7.7 million for the years ended 
December 31, 2024, 2023 and 2022, respectively. Sublease income is included in other income (expense) in our 
consolidated statements of operations. Rent received from the subtenant in excess of rent paid to the landlord is shared by 
paying the landlord 50% of the excess rent. The excess rent is considered a variable lease payment and the total estimated 
payments are being recognized as additional rent expense on a straight-line basis.
On February 22, 2024, our third-party subtenant obtained the approval of a voluntary petition for relief 
under Chapter 11 of the United States Code. As a consequence, the sublease agreement with that third-party for the 
subleased premises (approximately 75,662 square feet of office/laboratory space located at 5959 Horton Street, Emeryville, 
California) was terminated effective March 7, 2024. Simultaneously, on March 7, 2024, we entered into a new sublease 
agreement with a different third-party under similar conditions and for the same premises. See Note 8 - Commitments and 
Contingencies, in the accompanying notes to the consolidated financial statements included in Part II, Item 8, “Financial 
Statements and Supplementary Data” of this Annual Report on Form 10-K.
In May 2021, we issued $200.0 million aggregate principal amount of 2.50% convertible senior notes due 
2026 in a private placement. The purchasers also partially exercised their option to purchase additional Convertible Notes 
69

in May 2021 and we issued an additional $25.5 million of the Convertible Notes. As of December 31, 2024, the aggregate 
principal amount of our Convertible Notes was $225.5 million, excluding debt discount of $1.6 million. The Convertible 
Notes bear interest at a rate of 2.5% per year, payable semiannually in arrears on May 15 and November 15 of each year, 
beginning on November 15, 2021. The Convertible Notes mature on May 15, 2026, unless converted, redeemed or 
repurchased in accordance with their terms prior to such date. 
We have entered into material purchase commitments with commercial manufacturers for the supply of 
HEPLISAV-B. In November 2013, we entered into a Commercial Manufacturing and Supply Agreement with Baxter 
Pharmaceutical Solutions LLC (“Baxter”) that was amended in September 2021 and January 2025 (as amended, the 
“Baxter Agreement”). Baxter provides formulation, fill and finish services and produces HEPLISAV-B for commercial 
use. Pursuant to the Baxter Agreement, we are obligated to purchase an annual minimum number of batches of 
HEPLISAV-B through December 31, 2029, and there are certain limits on the number of batches that Baxter is required to 
produce. As of December 31, 2024, our aggregate minimum commitment under the Baxter Agreement was $17.0 million 
within the next 12 months, and $55.4 million beyond the next 12 months.
On September 7, 2023 (the “Effective Date”), we entered into an agreement (the “Avecia Supply 
Agreement”) with Nitto Denko Avecia Inc. (“Avecia”) for the manufacture and supply of our CpG 1018 adjuvant using a 
specific production process. Under the Avecia Supply Agreement, Avecia has agreed to produce and supply to us quantities 
of CpG 1018 adjuvant ordered by us after the Effective Date. Subject to certain conditions in the Avecia Supply 
Agreement, we are obligated to purchase all of our annual volume requirements of CpG 1018 adjuvant from Avecia up to a 
specified production capacity. We may alternatively order CpG 1018 adjuvant produced using a different production 
process pursuant to the existing supply agreement between us and Avecia dated October 1, 2012 (the “2012 Agreement”). 
As of December 31, 2024, our aggregate minimum commitment for the supply of CpG 1018 adjuvant under the Avecia 
Supply Agreement was $8.2 million for the 12 months following December 31, 2024.
In addition to the non-cancelable commitments noted above, we have entered into contractual arrangements 
that obligate us to make payments to the contractual counterparties upon the occurrence of future events. In addition, in the 
normal course of operations, we have entered into license and other agreements and intend to continue to seek additional 
rights relating to compounds or technologies in connection with our discovery, manufacturing and development programs. 
Under the terms of the agreements, we may be required to pay future up-front fees, milestones and royalties on net sales of 
products originating from the licensed technologies, if any, or other payments contingent upon the occurrence of future 
events that cannot reasonably be estimated.
We also rely on and have entered into agreements with research institutions, contract research organizations 
and clinical investigators as well as clinical material manufacturers. These agreements are typically terminable by us upon 
reasonable written notice. Generally, we are only obligated to pay for actual time spent and materials consumed by the 
organizations at any point in time during the contract through the notice period.
During 2004, we established a letter of credit with Deutsche Bank as security for our Düsseldorf lease in 
the amount of €0.20 (Euros). The letter of credit remained outstanding through December 31, 2024 and was collateralized 
by a certificate of deposit for €0.2 (Euros), which has been included in restricted cash in the consolidated balance sheets as 
of December 31, 2024.
In conjunction with our agreement with Symphony Dynamo, Inc. and Symphony Dynamo Holdings LLC 
(“Holdings”) in November 2009, we agreed to make contingent cash payments to Holdings equal to 50% of the first $50.0 
million from any upfront, pre-commercialization milestone or similar payments received by us from any agreement with 
any third party with respect to the development and/or commercialization of cancer and hepatitis C therapies originally 
licensed to Symphony Dynamo, Inc., including our immune-oncology compound, SD-101. In July 2020, we sold assets 
related to SD-101 to Surefire Medical, Inc. d/b/a TriSalus Life Sciences (“TriSalus”). We paid $2.5 million to Holdings in 
August 2020. In each of September 2021, May 2022 and September 2023, we received $1.0 million from TriSalus because 
it met pre-commercialization milestones. We recorded the proceeds as gain on sale of assets in our consolidated statements 
of operations. We paid Holdings $0.5 million in each of September 2021, May 2022 and October 2023. We included the 
payments in selling, general and administrative expenses in our consolidated statements of operations. No liability has been 
recorded under this agreement as of  December 31, 2024.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 
Quantitative and Qualitative Disclosure about Market Risk 
Interest Rate Risk 
We are subject to interest rate risk. Our investment portfolio is maintained in accordance with our 
investment policy, which defines allowable investments, specifies credit quality standards and limits the credit exposure of 
any single issuer. The primary objective of our investment activities is to preserve principal and, secondarily, to maximize 
income we receive from our investments without significantly increasing risk. Some of the securities that we invest in may 
have market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to 
fluctuate. To minimize this risk, we maintain our portfolio of cash equivalents and investments in highly liquid investments 
in money market funds, U.S. government agency securities, U.S. treasuries and corporate debt securities. We do not invest 
in auction rate securities or securities collateralized by home mortgages, mortgage bank debt or home equity loans. We do 
not have derivative financial instruments in our investment portfolio. To assess our risk, we calculate that if interest rates 
were to rise or fall from current levels by 100 basis points or by 125 basis points, the pro forma change in fair value of 
investments would be $9.0 million or $12.0 million as of December 31, 2024, compared to $7.0 million or $9.0 million as 
of December 31, 2023, respectively.
Due to the short duration and nature of our cash equivalents and marketable securities, as well as our 
intention to hold the investments to maturity, we do not expect any material loss with respect to our investment portfolio. 
Foreign Currency Risk 
We have certain investments outside the U.S. for the operations of Dynavax GmbH, Dynavax India LLP, 
and a branch of Dynavax registered in Italy, with exposure to foreign exchange rate fluctuations. The cumulative 
translation adjustment reported in the consolidated balance sheet as of December 31, 2024 and 2023 was a $5.3 million and 
$3.0 million loss, respectively, primarily related to the translation of Dynavax GmbH assets, liabilities and operating results 
from Euros to U.S. dollars. As of December 31, 2024 and 2023, the effect of our exposure to these exchange rate 
fluctuations has not been material, and we do not expect it to become material in the foreseeable future. We do not hedge 
our foreign currency exposures and have not used derivative financial instruments for speculation or trading purposes.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Dynavax Technologies Corporation
Opinion on the Financial Statements 
We have audited the accompanying consolidated balance sheets of Dynavax Technologies Corporation (the Company) as 
of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income (loss), 
stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2024, and the related 
notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial 
statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, 
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in 
conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (2013 framework), and our report dated February 20, 2025 expressed an unqualified opinion 
thereon.
Basis for Opinion 
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion 
on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 
financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures 
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits 
also included evaluating the accounting principles used and significant estimates made by management, as well as 
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our 
opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements 
that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex 
judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a 
separate opinion on the critical audit matter or on the account or disclosure to which it relates.
Reserves for returns on product revenue
Description of 
the Matter
During the year ended December 31, 2024, the Company’s net product revenues for HEPLISAV-
B were $268.4 million. As explained in Note 2 of the consolidated financial statements, revenue 
from product sales includes estimates of variable consideration for which reserves are established, 
including reserves for product returns.
Auditing the Company’s measurement of reserves for HEPLISAV-B product returns under its 
contracts with wholesalers and specialty distributors (collectively, “Customers”) was challenging 
because (1) the calculation involves management assumptions about the estimated returns on 
product sales that could be subject to return in future periods under the Company’s returns policy, 
and (2) the Company has limited returns history on which to base its assumptions.
73

How We 
Addressed the 
Matter in Our 
Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of 
internal controls that identified risks related to the Company’s process used to determine reserves 
for returns on product revenue. For example, we tested controls over management’s review of the 
completeness and accuracy of the data used in the process and the assumptions about the 
estimated returns on product sales.
To test the Company’s reserves for returns on product revenue, our audit procedures included, 
among other procedures, testing the accuracy and completeness of the underlying data used in the 
calculations and evaluating the assumptions used by management to estimate its reserves. To test 
management’s assumptions, we inspected the Company’s rights of return policy, obtained written 
representations from members of the commercial and market access functions regarding changes 
to the terms and conditions reported to the legal and accounting departments, examined credit 
memos issued during and after year end for unusual items or trends not consistent with the 
Company’s analysis of product returns and performed revenue cutoff testing at period end to 
assess whether there were unusual trends that should have been considered in the Company 
analysis of product returns. We also performed sensitivity analyses over the Company’s return 
rate to assess the effect of changes in assumptions.

DYNAVAX TECHNOLOGIES CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1.                      Organization
Dynavax Technologies Corporation (“we,” “our,” “us,” “Dynavax” or the “Company”) is a commercial 
stage biopharmaceutical company developing and commercializing innovative vaccines to help protect the world against 
infectious diseases. Our first marketed product, HEPLISAV-B® [Hepatitis B Vaccine (Recombinant), Adjuvanted] is 
approved in the United States, the European Union and the United Kingdom for the prevention of infection caused by all 
known subtypes of hepatitis B virus in adults aged 18 years and older. In May 2022, we commenced commercial shipments 
of HEPLISAV-B in Germany.
We are advancing a pipeline of differentiated product candidates that leverage our CpG 1018® adjuvant, 
the adjuvant used in HEPLISAV-B, to develop improved vaccines in indications with unmet medical needs. These 
programs include vaccine candidates under development for shingles and a plague vaccine candidate program in 
collaboration with, and fully funded by the U.S. Department of Defense ("DoD"), and additional vaccine programs in 
preclinical development.
Additionally. we manufacture and have supplied in the past CpG 1018 adjuvant, the adjuvant used in 
HEPLISAV-B, through both commercial supply agreements, and through preclinical and clinical research collaborations 
with third-party organizations. As of December 31, 2022, we had satisfied all delivery obligations under our commercial 
supply agreements. 
2.                      Summary of Significant Accounting Policies 
Basis of Presentation and Principles of Consolidation
The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting 
principles (“GAAP”) and include our accounts and those of our wholly-owned subsidiaries, Dynavax GmbH located in 
Düsseldorf, Germany, Dynavax India LLP in India and a branch of Dynavax in Italy. All intercompany accounts and 
transactions among the entities have been eliminated from the consolidated financial statements. 
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make informed 
estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying 
notes. Management’s estimates are based on historical information available as of the date of the consolidated financial 
statements and various other assumptions we believe are reasonable under the circumstances. Actual results may differ 
materially from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported 
results in the period in which they become known. 
Foreign Currency Translation
We consider the local currency to be the functional currency for our international subsidiaries, Dynavax 
GmbH, located in Düsseldorf, Germany, Dynavax India LLP, and a branch of Dynavax registered in Italy. Accordingly, 
assets and liabilities denominated in this foreign currency are translated into U.S. dollars using the exchange rate in effect 
on the balance sheet date. Revenues and expenses are translated at average exchange rates prevailing during the year. 
Currency translation adjustments arising from period to period are charged or credited to accumulated other comprehensive 
(loss) income in stockholders’ equity. 
As of December 31, 2024 and 2023, the cumulative translation adjustments balances reflected losses of 
$5.3 million and $3.0 million, respectively, primarily related to the translation of Dynavax GmbH assets, liabilities and 
operating results from Euros to U.S. dollars. For the years ended December 31, 2024, 2023 and 2022, we reported an 
unrealized foreign currency translation (loss) gain of $(2.4) million, $1.1 million and $(1.8) million, respectively. Realized 
gains and losses resulting from currency transactions are included in other (expense) income in the consolidated statements 
of operations. For the years ended December 31, 2024, 2023 and 2022, we reported a gain (loss) of $0.3 million, $(0.1) 
million and $0.1 million, respectively, resulting from currency transactions in our consolidated statements of operations.

Segment Information
Operating segments are defined as components of an entity for which discrete financial information is 
available that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate 
resources to an individual segment and in assessing performance. Our Chief Executive Officer is the CODM. The CODM 
reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating 
resources, and evaluating financial performance. As such, management has determined that we operate in one operating 
segment that is focused on the discovery, development, and commercialization of innovative vaccines. Net assets outside of 
the U.S. were less than 10% of total net assets as of December 31, 2024 and 2023. See Note 11.
Cash and Cash Equivalents and Marketable Securities 
We consider all liquid investments purchased with an original maturity of three months or less and that can 
be liquidated without prior notice or penalty to be cash equivalents. Management determines the appropriate classification 
of marketable securities at the time of purchase. In accordance with our investment policy, we invest in short-term money 
market funds, U.S. treasuries, U.S. government agency securities and corporate debt securities. We believe these types of 
investments are subject to minimal credit and market risk.
We have classified our entire investment portfolio as available-for-sale and available for use in current 
operations and accordingly have classified all investments as short-term. Available-for-sale securities are carried at fair 
value based on inputs that are observable, either directly or indirectly, such as quoted market prices for similar securities; 
quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market 
data for substantially the full term of the securities, with unrealized gains and losses included in accumulated other 
comprehensive loss in stockholders’ equity. Commencing with our adoption of Accounting Standards Codification 
(“ASC”) 326, Financial Instruments — Credit Losses (“ASC 326") on January 1, 2023, we determine whether a decline in 
the fair value of our available-for-sale ("AFS") debt securities below their amortized cost basis (i.e., an impairment) is due 
to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other 
comprehensive (loss) income, net of applicable taxes. Credit-related impairments (if any) are recognized as an allowance 
on the balance sheet with a corresponding adjustment to earnings. Both the allowance and the adjustment to net income can 
be reversed if conditions change. To date, there have been no declines in fair value that have been identified as a credit-
related impairment.
Concentration of Credit Risk and Other Risks and Uncertainties 
Financial instruments that are subject to concentration of credit risk consist primarily of cash equivalents, 
marketable securities and accounts receivable. 
Our policy is to invest cash in institutional money market funds and marketable securities of the U.S. 
government and corporate issuers with high credit quality to limit the amount of credit exposure. We currently maintain a 
portfolio of cash equivalents and marketable securities in a variety of securities, including short-term money market funds, 
U.S. treasuries, U.S. government agency securities and corporate debt securities. We have not experienced any significant 
losses on our cash equivalents and marketable securities. 
Our accounts receivable balance consists, primarily, of amounts due from product sales. Accounts 
receivable are recorded net of reserves for chargebacks, distribution fees, trade discounts and doubtful accounts. We 
estimate our allowance for doubtful accounts based on an evaluation of the aging of our receivables. Accounts receivable 
balances are written off against the allowance when it is probable that the receivable will not be collected. During the year 
ended December 31, 2023, we recorded an allowance for doubtful accounts of $12.3 million, which was determined by 
assessing changes in Biological E. Limited's (“Bio E”) credit risk, contemplation of ongoing negotiations relating to Bio E 
Amendment No. 3 (See Note 9), and Bio E's dependence on cash collections from the Government of India, which have 
been delayed and significantly reduced in connection with the overall reduction in demand for CORBEVAX from the 
Government of India. As of December 31, 2024 and 2023, three customers collectively represented approximately 97% and 
81% of our HEPLISAV-B trade receivable balance, respectively.
Our product candidates will require approval from the United States Food and Drug Administration 
("FDA") and foreign regulatory agencies before commercial sales can commence. There can be no assurance that our 
product candidates will receive any of these required approvals. The denial or delay of such approvals may have a material 
adverse impact on our business and may impact our business in the future. In addition, after the approval of HEPLISAV-B 
by the FDA, there is still an ongoing risk of adverse events that did not appear during the drug approval process that could 
affect our authorizations in the future.
81

We are subject to risks common to companies in the biopharmaceutical industry, including, but not limited 
to, new technological innovations, clinical development risk, establishment of appropriate commercial partnerships, 
protection of proprietary technology, compliance with government and environmental regulations, uncertainty of market 
acceptance of product candidates, product liability, the volatility of our stock price and the need to obtain additional 
financing.
Our long-lived assets located in the United States as of December 31, 2024 and 2023, represented 26% and 
31% of our total assets, respectively, and the remaining long-lived assets were located in Germany.
Inventories 
HEPLISAV-B Inventories
Inventory is stated at the lower of cost or estimated net realizable value, on a first-in, first-out, or FIFO, 
basis. We primarily use actual costs to determine our cost basis for inventories. Our assessment of market value requires 
the use of estimates regarding the net realizable value of our inventory balances, including an assessment of excess or 
obsolete inventory. We determine excess or obsolete inventory based on multiple factors, including an estimate of the 
future demand for our products, product expiration dates and current sales levels. Our assumptions of future demand for 
our products are inherently uncertain and if we were to change any of these judgments or estimates, it could cause a 
material increase or decrease in the amount of inventory reserves that we report in a particular period. For the years ended 
December 31, 2024 and 2023, there were no material inventory reserves or write-offs recognized. 
We consider regulatory approval of product candidates to be uncertain and product manufactured prior to 
the required regulatory approval may not be sold unless regulatory approval is obtained. As such, the manufacturing costs 
for product candidates incurred prior to regulatory approval are not capitalized as inventory. Instead, those are expensed as 
research and development costs. We begin capitalization of these inventory related costs once regulatory approval is 
obtained. 
Long-Lived Assets 
Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over 
the estimated useful lives of the respective assets. Additions, major renewals and improvements are capitalized, while 
repair and maintenance costs are charged to expense as incurred. Leasehold improvements are amortized over the 
remaining life of the initial lease term or the estimated useful lives of the assets, whichever is shorter.
We evaluate the carrying value of long-lived assets, whenever events or changes in business circumstances 
or our planned use of long-lived assets indicate, based on undiscounted future operating cash flows, that their carrying 
amounts may not be fully recoverable or that their useful lives are no longer appropriate. When an indicator of impairment 
exists, undiscounted future operating cash flows of long-lived assets are compared to their respective carrying value. Where 
the carrying value is greater than the undiscounted future operating cash flows of long-lived assets, the long-lived assets are 
written down to their respective fair values, and an impairment loss is recorded. Fair value is determined primarily using 
the discounted cash flows expected to be generated from the use of assets. Significant management judgment is required in 
the forecast of future operating results that are used in the preparation of expected cash flows. There have been no material 
adjustments to these estimates during the years presented.
Leases
We determine if an arrangement is or contains a lease at inception by assessing whether the arrangement 
contains an identified asset, and whether we have the right to control the identified asset. Operating leases are included in 
operating lease right-of-use (“ROU”) assets, other current liabilities and long-term portion of lease liabilities in our 
consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term, and lease 
liabilities represent our obligation to make lease payments arising from the lease. The classification of our leases as 
operating or finance leases along with the initial measurement and recognition of the associated ROU assets and lease 
liabilities is performed at the lease commencement date. The measurement of ROU assets and lease liabilities is based on 
the present value of future lease payments over the lease term. The ROU asset also includes the effect of any lease 
payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as 
applicable. 
As the implicit rate in our leases is generally unknown, we use our incremental borrowing rate based on 
information available at the lease commencement date in determining the present value of future lease payments. We 
consider our credit risk, term of the lease, total lease payments and adjust for the impacts of collateral, as necessary, when 
82

calculating our incremental borrowing rate. The lease terms may include options to extend or terminate the lease when it is 
reasonably certain we will exercise any such options. Rent expense for our operating leases is recognized on a straight-line 
basis over the lease term. Variable lease payments are recorded as an expense in the period incurred.
We have elected not to apply the recognition requirements of ASC 842, Leases ("ASC 842"), for short-term 
leases. We have also elected the practical expedient to not separate lease components from non-lease components.
As lessors, we determine if an arrangement includes a lease at inception. We elected the practical expedient 
to not separate lease components from non-lease components. Sublease income is recognized on a straight-line basis over 
the expected lease term and is included in other income (expense) in our consolidated statements of operations.
Goodwill
Goodwill represents the excess purchase price over the fair value of tangible and intangible assets acquired 
and liabilities assumed. Our goodwill balance relates to our acquisition of Dynavax GmbH in 2006. Goodwill is not 
amortized, but instead is reviewed for impairment at least annually, or more frequently if events occur or circumstances 
change that would indicate the carrying amount may be impaired. Goodwill is assigned to, and impairment testing is 
performed at, the reporting unit level. We determined that we have only one operating segment and there are no 
components of that operating segment that are deemed to be separate reporting units, such that we have one reporting unit 
for purposes of our goodwill impairment testing. No impairment has been identified for the years presented.
Convertible Notes 
We account for our 2.50% convertible senior notes due in 2026 (“Convertible Notes”), as a long-term 
liability equal to the proceeds received from issuance, including the embedded conversion feature, net of the unamortized 
debt issuance and offering costs on the consolidated balance sheets (See Note 10). We evaluate all conversion, repurchase 
and redemption features contained in a debt instrument to determine if there are any embedded features that require 
bifurcation as a derivative. The conversion feature is not required to be accounted for separately as an embedded derivative. 
We amortize debt issuance and offering costs over the contractual term of the Convertible Notes, using the effective 
interest method, as interest expense on the consolidated statements of operations.
Capped Calls 
We evaluate financial instruments under ASC 815, Derivatives and Hedging ("ASC 815"). The capped calls 
purchased in connection with the Convertible Notes financing ("Capped Calls") cover the same number of shares of 
common stock that initially underlie the Convertible Notes (subject to anti-dilution and certain other adjustments). The 
Capped Calls meet the definition of derivative under ASC 815. In addition, the Capped Calls meet the conditions in ASC 
815 to be classified in stockholders’ equity and are not subsequently remeasured as long as the conditions for the equity 
classification continue to be met. 
Revenue Recognition 
We recognize revenue when the customer obtains control of promised goods or services, in an amount that 
reflects the consideration, which we expect to receive in exchange for those goods or services. To determine revenue 
recognition for arrangements that we determine are within the scope of ASC 606, Revenue from Contracts with Customers 
("ASC 606"), we apply the following five step model:
•
identify the contract(s) with a customer;
•
identify the performance obligation(s) in the contract;
•
determine the transaction price;
•
allocate the transaction price to the performance obligation(s) in the contract; and 
•
recognize revenue when (or as) we satisfy a performance obligation. 
Product Revenue, Net – HEPLISAV-B
We sell HEPLISAV-B to a limited number of wholesalers and specialty distributors in the U.S. 
(collectively, our “Customers”). 
83

Revenues from product sales are recognized when we have satisfied our performance obligation, which is 
the transfer of control of our product upon delivery to the Customer. The timing between the recognition of revenue for 
product sales and the receipt of payment is not significant. Because our standard credit terms are short-term and we expect 
to receive payment in less than one-year, there is no significant financing component on the related receivables. Taxes 
collected from Customers relating to product sales and remitted to governmental authorities are excluded from revenues. 
Since our performance obligation is part of a contract that has an original expected duration of one year or less, we elect 
not to disclose the information about our remaining performance obligations.
Overall, product revenue, net - HEPLISAV-B, reflects our best estimates of the amount of consideration to 
which we are entitled based on the terms of the contract. The amount of variable consideration is included in the net sales 
price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized 
will not occur in a future period. If our estimates differ significantly from actuals, we will record adjustments that would 
affect product revenue, net in the period of adjustment.
Reserves for Variable Consideration
Revenues from product sales are recorded at the net sales price, which includes estimates of variable 
consideration such as product returns, chargebacks, discounts, rebates and other fees that are offered within contracts 
between us and our Customers, healthcare providers, pharmacies and others relating to our product sales. We estimate 
variable consideration using either the most likely amount method or the expected value method, depending on the type of 
variable consideration and what method better predicts the amount of consideration we expect to receive. We take into 
consideration relevant factors such as industry data, current contractual terms, available information about Customers’ 
inventory, resale and chargeback data and forecasted customer buying and payment patterns, in estimating each variable 
consideration. The variable consideration is recorded at the time product sales is recognized, resulting in a reduction in 
product revenue and a reduction in accounts receivable (if the Customer offsets the amount against its accounts receivable) 
or as an accrued liability (if we pay the amount through our accounts payable process). Variable consideration requires 
significant estimates, judgment and information obtained from external sources. The amount of variable consideration is 
included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the 
cumulative revenue recognized will not occur in a future period. If our estimates differ significantly from actuals, we will 
record adjustments that would affect product revenue, net in the period of adjustment. If we were to change any of these 
judgments or estimates, it could cause a material increase or decrease in the amount of revenue that we report in a 
particular period. We evaluate our estimates of variable considerations including, but not limited to, product returns, 
chargebacks and rebates, periodically or when there is an event or change in circumstances that may indicate that our 
estimates may change. 
Product Returns: Consistent with industry practice, we offer our Customers a limited right of return based 
on the product’s expiration date for product that has been purchased from us. We estimate the amount of our product sales 
that may be returned by our Customers and record this estimate as a reduction of revenue in the period the related product 
revenue is recognized. We consider several factors in the estimation of potential product returns including expiration dates 
of the product shipped, the limited product return rights, available information about Customers’ inventory and other 
relevant factors. 
Chargebacks: Our Customers subsequently resell our product to healthcare providers, pharmacies and 
others. In addition to distribution agreements with Customers, we enter into arrangements with qualified healthcare 
providers that provide for chargebacks and discounts with respect to the purchase of our product. Chargebacks represent 
the estimated obligations resulting from contractual commitments to sell product to qualified healthcare providers at prices 
lower than the list prices charged to Customers who directly purchase the product from us. Customers charge us for the 
difference between what they pay for the product and the ultimate selling price to the qualified healthcare providers. These 
reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product 
revenue and accounts receivable. Chargeback amounts are determined at the time of resale to the qualified healthcare 
providers by Customers, and we issue credits for such amounts generally within a few weeks of the Customer’s notification 
to us of the resale. Reserves for chargebacks consists of credits that we expect to issue for units that remain in the 
distribution channel inventories at each reporting period end that we expect will be sold to the qualified healthcare 
providers, and chargebacks for units that our Customers have sold to the qualified healthcare providers, but for which 
credits have not been issued.
Trade Discounts and Allowances: We provide our Customers with discounts which include early payment 
incentives that are explicitly stated in our contracts, and are recorded as a reduction of revenue in the period the related 
product revenue is recognized. 
84

Distribution Fees: Distribution fees include fees paid to certain Customers for sales order management, 
data and distribution services. Distribution fees are recorded as a reduction of revenue in the period the related product 
revenue is recognized.
Rebates: Under certain contracts, Customers may obtain rebates for purchasing minimum volumes of our 
product. We estimate these rebates based upon the expected purchases and the contractual rebate rate and record this 
estimate as a reduction in revenue in the period the related revenue is recognized.
Other Revenue
Other revenue includes revenue from our agreement with the DoD, collaboration and manufacturing service 
revenue. We have entered into grant agreements, collaborative arrangements and arrangements to provide manufacturing 
services to other companies. Such arrangements may include promises to customers which, if capable of being distinct, are 
accounted for as separate performance obligations. For agreements with multiple performance obligations, we allocate 
estimated revenue to each performance obligation at contract inception based on the estimated transaction price of each 
performance obligation. Revenue allocated to each performance obligation is then recognized when we satisfy the 
performance obligation by transferring control of the promised good or service to the customer. 
Research and Development Expenses and Accruals 
Research and development expenses include personnel and facility-related expenses, outside contracted 
services including clinical trial costs, manufacturing and process development costs, research costs and other consulting 
services and non-cash stock-based compensation. Research and development costs are expensed as incurred. Amounts due 
under contracts with third parties may be either fixed fee or fee for service, and may include upfront payments, monthly 
payments and payments upon the completion of milestones or receipt of deliverables. Non-refundable advance payments 
under agreements are capitalized and expensed as the related goods are delivered or services are performed.
We contract with third parties to perform various clinical trial activities in the on-going development of 
potential products. The financial terms of these agreements are subject to negotiation, vary from contract to contract and 
may result in uneven payment flows to our vendors. Payments under the contracts depend on factors such as the 
achievement of certain events, successful enrollment of patients, and completion of portions of the clinical trial or similar 
conditions. Our accrual for clinical trials is based on estimates of the services received and efforts expended pursuant to 
contracts with clinical trial centers and clinical research organizations. We may terminate these contracts upon written 
notice and we are generally only liable for actual effort expended by the organizations to the date of termination, although 
in certain instances we may be further responsible for termination fees and penalties. We estimate research and 
development expenses and the related accrual as of each balance sheet date based on the facts and circumstances known to 
us at that time. There have been no material adjustments to the prior period accrued estimates for clinical trial activities 
during the years presented. 
Stock-Based Compensation
Stock-based compensation expense for restricted stock units ("RSUs"), market-based performance stock 
units ("PSUs") and stock options is estimated at the grant date based on the award’s estimated fair value.
For awards that vest based on service conditions and market conditions, we use a straight-line method to 
recognize compensation expense over the award’s requisite service period, assuming estimated forfeiture rates. For awards 
that contain performance conditions, we determine the appropriate amount to expense at each reporting date based on the 
anticipated achievement of performance targets, which requires judgement, including forecasting the achievement of future 
specified targets. At the date performance conditions are determined to be probable of achievement, we record a 
cumulative expense catch-up, with remaining expense amortized over the remaining service period. Throughout the 
performance period, we re-assesses the estimated performance and updates the number of performance-based awards that 
we believe will ultimately vest. 
Fair value of RSUs is determined at the date of grant using our closing stock price, with the exception of 
PSUs, which are measured using the Monte Carlo simulation method on the date of grant. Our determination of the fair 
value of stock options on the date of grant using an option-pricing model is affected by our stock price, as well as 
assumptions regarding a number of subjective variables. We selected the Black-Scholes option pricing model as the most 
appropriate method for determining the estimated fair value-based measurement of our stock options. The Black-Scholes 
model requires the use of subjective assumptions, which determine the fair value-based measurement of stock options. 
These assumptions include, but are not limited to, our expected stock price volatility over the term of the awards, and 
85

projected employee stock option exercise behaviors. In the future, as additional empirical evidence regarding these input 
estimates becomes available, we may change or refine our approach of deriving these input estimates. These changes could 
impact our fair value of stock options granted in the future. Changes in the fair value of stock awards could materially 
impact our operating results. 
Our current estimate of volatility is based on the historical volatility of our stock price. To the extent 
volatility in our stock price increases in the future, our estimates of the fair value of options granted in the future could 
increase, thereby increasing stock-based compensation expense recognized in future periods. We derive the expected term 
assumption primarily based on our historical settlement experience, while considering options that have not yet completed 
a full life cycle. Stock-based compensation expense is recognized only for awards ultimately expected to vest. Our estimate 
of the forfeiture rate is based primarily on our historical experience. To the extent we revise this estimate in the future, our 
share-based compensation expense could be materially impacted in the period of revision. There have been no material 
adjustments to these estimates during the years presented.
Income Taxes
The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected 
future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. 
Tax law and rate changes are reflected in income in the period such changes are enacted. We include interest and penalties 
related to income taxes, including unrecognized tax benefits, within income tax expense.
Our income tax returns are based on calculations and assumptions that are subject to examination by the 
Internal Revenue Service and other tax authorities. In addition, the calculation of our tax liabilities involves dealing with 
uncertainties in the application of complex tax regulations. We recognize liabilities for uncertain tax positions based on a 
two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available 
evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related 
appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 
50% likely of being realized upon settlement. While we believe we have appropriate support for the positions taken on our 
tax returns, we regularly assess the potential outcomes of examinations by tax authorities in determining the adequacy of 
our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and adjust the 
income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision 
become known.
Judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities 
and the valuation allowance recorded against our net deferred tax assets. Deferred tax assets and liabilities are determined 
using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation 
allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will 
not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis 
and includes a review of all available positive and negative evidence, including future reversals of existing taxable 
temporary differences, projected future taxable income, tax planning strategies and recent financial operations. 
Based on all available evidence, both positive and negative, and the weight of that evidence to the extent 
such evidence can be objectively verified, we believe that recognition of the deferred tax assets arising from future tax 
benefits is currently not more likely than not to be realized and, accordingly, we have determined a need for a full valuation 
allowance.
Recent Accounting Pronouncements
In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-07, Segment 
Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose 
information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. 
Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well 
as all existing segment disclosures and reconciliation requirements in ASC 280 on an interim and annual basis. ASU 
2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years 
beginning after December 15, 2024, with early adoption permitted. We adopted ASU 2023-07 in the fiscal year beginning 
January 1, 2024. The adoption of this guidance did not have a material impact on our consolidated financial statements.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income 
Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate 
reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal 
86

years beginning after December 15, 2024, with early adoption permitted. We are currently evaluating the impact of 
adopting ASU 2023-09.
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income 
- Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires 
the disaggregation of certain expense captions into specified categories in disclosures within the notes to the financial 
statements to provide enhanced transparency into the expense captions presented on the face of the income statement. ASU 
2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim periods beginning after 
December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively to financial 
statements issued for reporting periods after the effective date of ASU 2024-03 or retrospectively to any or all prior periods 
presented in the financial statements. We are currently evaluating the impact of adopting ASU 2024-03.
In November 2024, the FASB issued ASU 2024-04, Debt with Conversion and Other Options (Subtopic 
470-20): Induced Conversions of Convertible Debt Instruments, which amends ASC 470-202 and seeks to clarify the 
requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an 
induced conversion. ASU 2024-04 is effective for all entities for annual reporting periods beginning after 15 December 
2025, and interim periods within those annual reporting periods. Early adoption is permitted for all entities that have 
adopted the amendments in ASU 2020-06. We are currently evaluating the impact of adopting ASU 2024-04.
3.                      Fair Value Measurements 
We measure fair value as the exchange price that would be received for an asset or paid to transfer a 
liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction 
between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the 
use of observable inputs and minimize the use of unobservable inputs. The accounting standard describes a fair value 
hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that 
may be used to measure fair value which are the following:
•
Level 1—Observable inputs, such as quoted prices in active markets for identical assets or 
liabilities; 
•
Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as 
quoted prices for similar assets or liabilities, quoted prices in markets that are not active or 
other inputs that are observable or can be corroborated by observable market data for 
substantially the full term of the assets or liabilities; and 
•
Level 3—Unobservable inputs that are supported by little or no market activity and that are 
significant to the fair value of the assets or liabilities; therefore, requiring an entity to develop 
its own valuation techniques and assumptions. 
Assets and liabilities are classified based on the lowest level of input that is significant to the fair value 
measurements. We review the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe 
valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. 
There were no transfers between Level 1, 2 and 3 during the years ended December 31, 2024 and 2023.
The carrying amounts of cash equivalents, accounts and other receivables, accounts payable and accrued 
liabilities are considered reasonable estimates of their respective fair value because of their short-term nature.

Money market funds are highly liquid investments and are actively traded. The pricing information on these 
investment instruments is readily available and can be independently validated as of the measurement date. This approach 
results in the classification of these securities as Level 1 of the fair value hierarchy.
U.S. treasuries, U.S. government agency securities and corporate debt securities are measured at fair value 
using Level 2 inputs. We review trading activity and pricing for these investments as of each measurement date. When 
sufficient quoted pricing for identical securities is not available, we use market pricing and other observable market inputs 
for similar securities obtained from various third-party data providers. These inputs represent quoted prices for similar 
assets in active markets or these inputs have been derived from observable market data. This approach results in the 
classification of these securities as Level 2 of the fair value hierarchy.

We have classified our entire investment portfolio as available-for-sale ("AFS") and available for use in 
current operations and accordingly have classified all investments as short-term. Our AFS securities are carried at fair value 
based on inputs that are observable, either directly or indirectly, such as quoted market prices for similar securities, quoted 
prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data 
for substantially the full term of the securities. Unrealized losses are included in accumulated other comprehensive loss in 
stockholders’ equity. We determine whether a decline in the fair value of our AFS debt securities below their amortized 
cost basis (i.e., an impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit 
related is recognized in other comprehensive (loss) income, net of applicable taxes. Credit-related impairments (if any) are 
recognized as an allowance on the balance sheet with a corresponding adjustment to earnings. Both the allowance and the 
adjustment to net income can be reversed if conditions change.
There were no realized gains or losses from the sale of marketable securities for the years ended 
December 31, 2024 and 2023. We do not intend to sell, and are not required to sell, the investments that are in an 
89

unrealized loss position before recovery of their amortized cost basis. For the year ended December 31, 2024, we did not 
record an allowance for credit losses, as management believes any such losses would be immaterial based on the 
investment-grade credit rating for each of the investments as of December 31, 2024. As such, there have been no declines 
in fair value that have been identified as a credit-related impairment.

8.                      Commitments and Contingencies
Leases
We lease our facilities in Emeryville, California and Düsseldorf, Germany. We lease and sublease certain 
manufacturing and office space with lease terms ranging from 3 to 12 years. These leases require monthly lease payments 
that may be subject to annual increases throughout the lease term. Certain of these leases also include options to renew or 
extend the lease for two successive five-year terms. These optional periods have not been considered in the determination 
of the right-of-use assets or lease liabilities associated with these leases as we did not consider the exercise of these options 
to be reasonably certain.
Sublease Termination and New Sublease
On February 22, 2024, our third-party subtenant obtained the approval of a voluntary petition for relief 
under Chapter 11 of the United States Code. As a consequence, the sublease agreement with that third-party for the 
subleased premises (approximately 75,662 square feet of office/laboratory space located at 5959 Horton Street, Emeryville, 
California) was terminated effective March 7, 2024. Simultaneously, on March 7, 2024, we entered into a new sublease 
agreement with a different third-party under similar conditions and for the same premises. Rent from the new sublease 
agreement is subject to scheduled annual increases, and the subtenant is responsible for certain operating expenses and 
taxes throughout the life of the sublease. The new sublease term expires on March 31, 2031, unless earlier terminated, 
concurrent with the term of our lease. The subtenant has no option to extend the sublease term.
As a result of the termination of the existing sublease agreement, we recognized a net loss of approximately 
$3.5 million during the year ended December 31, 2024, comprising primarily of a $4.8 million write-off of the accrued rent 
asset balance as of March 7, 2024, partially offset by the collection of a termination payment of $1.3 million.
We also sublease one of our leased premises to a third party. Rent is subject to scheduled annual increases 
and the subtenant is responsible for certain operating expenses and taxes throughout the life of the sublease. The sublease 
term expires on March 31, 2031, unless earlier terminated, concurrent with the term of our lease. The subtenant has no 
option to extend the sublease term. Sublease income was $5.0 million, $7.6 million and $7.7 million for the years ended 
December 31, 2024, 2023 and 2022, respectively. Both the net loss on sublease termination and the sublease income are 
included net in “Sublease income” within “Other income (expense)” in our consolidated statements of operations. Rent 
received from the subtenant in excess of rent paid to the landlord shall be shared by paying the landlord 50% of the excess 
rent. The excess rent is considered a variable lease payment and the total estimated payments are being recognized as 
additional rent expense on a straight-line basis.

The amounts presented in the table above include obligations under a contract that was executed subsequent to December 31, 2024. These obligations 
have been included to provide a comprehensive view of our future commitments as of the filing date of this report.
We have entered into material purchase commitments with commercial manufacturers for the supply of 
HEPLISAV-B. In November 2013, we entered into a Commercial Manufacturing and Supply Agreement with Baxter 
Pharmaceutical Solutions LLC (“Baxter”) that was amended in September 2021 and January 2025 (as amended, the 
“Baxter Agreement”). Baxter provides formulation, fill and finish services and produces HEPLISAV-B for commercial 
use. Pursuant to the Baxter Agreement, we are obligated to purchase an annual minimum number of batches of 
HEPLISAV-B through December 31, 2029, and there are certain limits on the number of batches that Baxter is required to 
produce. As of December 31, 2024, our aggregate minimum commitment under the Baxter Agreement was $17.0 million 
within the next 12 months, and $55.4 million beyond the next 12 months.
On September 7, 2023 (the “Effective Date”), we entered into an agreement (the “Avecia Supply 
Agreement”) with Nitto Denko Avecia Inc. (“Avecia”) for the manufacture and supply of our CpG 1018 adjuvant using a 
specific production process. Under the Avecia Supply Agreement, Avecia has agreed to produce and supply to us quantities 
92

of CpG 1018 adjuvant ordered by us after the Effective Date. Subject to certain conditions in the Avecia Supply 
Agreement, we are obligated to purchase all of our annual volume requirements of CpG 1018 adjuvant from Avecia up to a 
specified production capacity. We may alternatively order CpG 1018 adjuvant produced using a different production 
process pursuant to the existing supply agreement between us and Avecia dated October 1, 2012 (the “2012 Agreement”). 
As of December 31, 2024, our aggregate minimum commitment for the supply of CpG 1018 adjuvant under the Avecia 
Supply Agreement was $8.2 million within the next 12 months. 
In addition to the non-cancelable commitments included above, we have entered into contractual 
arrangements that obligate us to make payments to the contractual counterparties upon the occurrence of future events. In 
addition, in the normal course of operations, we have entered into license and other agreements and intend to continue to 
seek additional rights relating to compounds or technologies in connection with our discovery, manufacturing and 
development programs. Under the terms of the agreements, we may be required to pay future up-front fees, milestones and 
royalties on net sales of products originating from the licensed technologies, if any, or other payments contingent upon the 
occurrence of future events that cannot reasonably be estimated.
We also rely on and have entered into agreements with research institutions, contract research organizations 
and clinical investigators as well as clinical material manufacturers. These agreements are terminable by us upon written 
notice. Generally, we are liable only for actual effort expended by the organizations at any point in time during the contract 
through the notice period.
As of December 31, 2024, the aggregate principal amount of our convertible senior notes ("Convertible 
Notes") was $225.5 million, excluding debt discount of $1.6 million (See Note 10). 
During 2004, we established a letter of credit with Deutsche Bank as security for our Düsseldorf lease in 
the amount of €0.2 million (Euros). The letter of credit remained outstanding through December 31, 2024 and was 
collateralized by a certificate of deposit for €0.2 million, which has been included in restricted cash in the consolidated 
balance sheets as of December 31, 2024 and 2023.
In conjunction with our agreement with Symphony Dynamo, Inc. and Symphony Dynamo Holdings LLC 
(“Holdings”) in November 2009, we agreed to make contingent cash payments to Holdings equal to 50% of the first $50 
million from any upfront, pre-commercialization milestone or similar payments received by us from any agreement with 
any third party with respect to the development and/or commercialization of cancer and hepatitis C therapies originally 
licensed to Symphony Dynamo, Inc., including our immune-oncology compound, SD-101. In July 2020, we sold assets 
related to SD-101 to Surefire Medical, Inc. d/b/a TriSalus Life Sciences (“TriSalus”). We paid $2.5 million to Holdings in 
August 2020. In each of September 2021, May 2022 and September 2023, we received $1.0 million from TriSalus because 
it met pre-commercialization milestones. We recorded the proceeds as gain on sale of assets in our consolidated statements 
of operations. We paid Holdings $0.5 million in each of September 2021, May 2022 and October 2023. We included the 
payments in selling, general and administrative expenses in our consolidated statements of operations. 
Contingencies
From time to time, we may be involved in claims, suits, and proceedings arising from the ordinary course 
of our business, including actions with respect to intellectual property claims, commercial claims, and other matters. Such 
claims, suits, and proceedings are inherently uncertain and their results cannot be predicted with certainty. Regardless of 
the outcome, such legal proceedings can have an adverse impact on us because of legal costs, diversion of management 
resources, and other factors. In addition, it is possible that a resolution of one or more such proceedings could result in 
substantial damages, fines, penalties or orders requiring a change in our business practices, which could in the future 
materially and adversely affect our financial position, results of operations, or cash flows in a particular period.
9.                      Collaborative Research, Development and License Agreements 
Coalition for Epidemic Preparedness Innovations 
In January 2021, we entered into an agreement (together with subsequent amendments, the “CEPI 
Agreement”) with Coalition for Epidemic Preparedness Innovations (“CEPI”) for the manufacture and reservation of a 
specified quantity of CpG 1018 adjuvant (“CpG 1018 Materials”). In May 2021, we entered into the first amendment to the 
CEPI Agreement. The CEPI Agreement enables CEPI to direct the supply of CpG 1018 Materials to CEPI partner(s). CEPI 
partner(s) would purchase CpG 1018 Materials under separately negotiated agreements. The CEPI Agreement also allows 
us to sell CpG 1018 Materials to third parties if not purchased by a CEPI partner within a two-year term.
93

In exchange for reserving CpG 1018 Materials and agreeing to sell CpG 1018 Materials to CEPI partner(s) 
at pre-negotiated prices, CEPI agreed to provide payments in the form of an interest-free, unsecured, forgivable loan (the 
“Advance Payments”). We are obligated to repay the Advance Payments, in proportion to quantity sold, if and to the extent 
we receive payments from sales of CpG 1018 Materials reserved under the CEPI Agreement. If the vaccine programs 
pursued by CEPI partner(s) are unsuccessful and no alternative use is found for CpG 1018 Materials reserved under the 
CEPI Agreement, the applicable Advance Payments will be forgiven at the end of the two-year term.
On April 27, 2023, we entered into a waiver and second amendment to the CEPI Agreement by and 
between us and CEPI (the “CEPI-Bio E Assignment Agreement”). Pursuant to the CEPI-Bio E Assignment Agreement, 
CEPI has forgiven the entirety of the outstanding Advance Payments for CpG 1018 Materials allocated to and ordered by 
Bio E under the CEPI Agreement and has assumed our previous rights to $47.4 million of Bio E accounts receivable.
Through December 31, 2024, we received Advance Payments totaling approximately $175.0 million 
pursuant to the CEPI Agreement, of which $67.3 million have been repaid and $47.4 million have been forgiven (as 
discussed above). As of December 31, 2024, remaining Advance Payments totaling $60.3 million in CEPI accrual long-
term were reflected in our consolidated balance sheets, representing the outstanding balance of the Advance Payments 
relating to the Clover Supply Agreement (as defined and discussed below). There were no deferred revenue balances 
related to the CEPI Agreement as of December 31, 2024 and December 31, 2023.
Zhejiang Clover Biopharmaceuticals, Inc. and Clover Biopharmaceuticals (Hong Kong) Co., Limited
In June 2021, we entered into an agreement with Zhejiang Clover Biopharmaceuticals, Inc. and Clover 
Biopharmaceuticals (Hong Kong) Co., Limited (collectively, “Clover”), for the commercial supply of CpG 1018 adjuvant, 
for use with Clover’s COVID-19 vaccine candidate, SCB-2019 (together with subsequent amendments, the “Clover Supply 
Agreement”). Under the Clover Supply Agreement, Clover committed to purchase specified quantities of CpG 1018 
adjuvant, at pre-negotiated prices pursuant to the CEPI Agreement, for use in Clover’s commercialization of vaccines 
containing SCB-2019 and CpG 1018 adjuvant (“Clover Product”). The Clover Supply Agreement also provides terms for 
Clover to order additional quantities of CpG 1018 adjuvant beyond the quantities reserved by CEPI. In 2022 and 2023, we 
signed four amendments to the Clover Supply Agreement. The terms and conditions of the Clover Supply Agreement were 
operative through December 31, 2022, and as of December 31, 2022, we had satisfied all delivery obligations thereunder.
For CpG 1018 adjuvant reserved for Clover under the CEPI Agreement, Clover is obligated to pay us the 
purchase price upon the earliest of (i) the true-up exercise, (ii) within a specified period after Clover delivers Clover 
Product to a customer, or (iii) Clover’s receipt of payment for Clover Product from a customer. When we transfer control 
of CpG 1018 adjuvant that is reserved under the CEPI Agreement, we recognize product revenue and a corresponding 
contract asset as our right to consideration is contingent on something other than the passage of time, as outlined above. 
The contract asset of $71.3 million relating to Clover was included in other current assets as of 
December 31, 2024 and December 31, 2023. The contract asset was included in other assets (long term) to reflect the 
timing of expected long term demand for CpG 1018 adjuvant for Clover Product.
Corresponding Advance Payments of $60.3 million relating to Clover are recorded in CEPI accrual long-
term in our consolidated balance sheets as of December 31, 2024. These Advance Payments may be repaid using cash 
collected from Clover or forgiven in accordance with the CEPI Agreement. We had no accounts receivable balance from 
Clover as of December 31, 2024 and December 31, 2023. 
Biological E. Limited
In July 2021, we entered into an agreement (together with subsequent amendments, the “Bio E Supply 
Agreement”) with Biological E. Limited (“Bio E”), for the commercial supply of CpG 1018 adjuvant, for use with Bio E’s 
subunit COVID-19 vaccine candidate, CORBEVAX™. Under the Bio E Supply Agreement, Bio E committed to purchase 
specified quantities of CpG 1018 adjuvant, at pre-negotiated prices pursuant to the CEPI Agreement, for use in Bio E’s 
commercialization of its CORBEVAX vaccine (“Bio E Product”) with specified delivery dates in 2021 and the first quarter 
of 2022. The Bio E Supply Agreement also provides terms for Bio E to order additional quantities of CpG 1018 adjuvant 
beyond the quantities reserved by CEPI. In June 2022 and in October 2022, we entered into amendments to the Bio E 
Supply Agreement (the “Bio E Amendment No. 1” and the “Bio E Amendment No. 2,” together the “Bio E 
Amendments”). The Bio E Amendments primarily established: (i) a new payment schedule for certain outstanding invoices 
related to the CEPI product to be the earlier of December 31, 2022, or receipt of certain amounts from Bio E from the 
Government of India in connection with their advance purchase agreement for CORBEVAX, and (ii) further modified the 
scope of the Bio E Supply Agreement, by reducing certain quantities of CpG 1018 adjuvant to be delivered. The terms and 
94

conditions of the Bio E Supply Agreement were operative through December 31, 2022, and as of December 31, 2022, we 
had satisfied all delivery obligations thereunder.
As of December 31, 2024, we had no accounts receivable balance from Bio E. In 2023, we recorded an 
allowance for doubtful accounts of $12.3 million, which was determined by assessing changes in Bio E’s credit risk, 
contemplation of ongoing negotiations relating to Bio E Amendment No. 3 (defined below), and Bio E's dependence on 
cash collections from the Government of India, which have been delayed and significantly reduced in connection with the 
overall reduction in demand for CORBEVAX from the Government of India.
On April 26, 2023, we entered into a third amendment to the Bio E Supply Agreement (the “Bio E 
Amendment No. 3”), and on April 27, 2023, we entered into the CEPI-Bio E Assignment Agreement. Pursuant to the 
CEPI-Bio E Assignment Agreement, CEPI has forgiven the entirety of remaining amounts outstanding relating to a liability 
for Advance Payments of $47.4 million (the “Bio E CEPI Advance Payments”) for CpG 1018 Materials allocated to Bio E, 
and has assumed our previous rights to collect $47.4 million of Bio E accounts receivable. Pursuant to the Bio E 
Amendment No. 3, we collected $14.5 million from Bio E (including $13.5 million in April 2023 and $1.0 million in 
August 2023). Accordingly, as of December 31, 2024, the CEPI-Bio E Assignment Agreement resulted in: (i) no accounts 
receivable balance, and (ii) the derecognition of $47.4 million CEPI accrual in connection with the Bio E CEPI Advance 
Payments. The Bio E Amendment No. 3 provides for additional future payment of either $5.5 million in the event that Bio 
E receives at least $125.0 million, or $12.3 million in the event that Bio E receives at least $250.0 million in future 
payments from the Government of India associated with its CORBEVAX product on or before August 15, 2025. These 
additional amounts are not considered collectible until the achievement of these future milestones.
U.S. Department of Defense
In September 2021, we entered into an agreement with the DoD for the development of a recombinant 
plague vaccine adjuvanted with CpG 1018 adjuvant for approximately $22.0 million over two and a half years. Under the 
agreement, we are conducting a Phase 2 clinical trial combining our CpG 1018 adjuvant with the DoD's rF1V vaccine. In 
July 2023, we executed a contract modification with the DoD to support advancement into a nonhuman primate challenge 
study, with the agreement now totaling $33.7 million through 2025. In December 2024, we executed a contract totaling 
$30.0 million to support additional Phase 2 clinical and manufacturing activities to be performed through the first half of 
2027.
For the years ended December 31, 2024 and 2023, we recognized revenue of $8.6 million and $17.6 
million, respectively, from the DoD agreement, which is included in other revenue in our consolidated statements of 
operations. 
10.                    Convertible Notes
In May 2021, we issued $225.5 million of Convertible Notes in a private placement. Total proceeds from 
the issuance of the Convertible Notes, net of debt issuance and offering costs of $5.7 million, were $219.8 million. We 
used $190.2 million of the net proceeds to retire our previous loan agreement with CRG Servicing LLC and $27.2 million 
of the net proceeds to pay the costs of the Capped Calls described below. 
The Convertible Notes are general, unsecured obligations and accrue interest at a rate of 2.5% per annum 
payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2021. The 
Convertible Notes mature on May 15, 2026, unless converted, redeemed or repurchased prior to such date.
The Convertible Notes are convertible into cash, shares of our common stock or a combination of cash and 
shares of our common stock, at our election, at an initial conversion rate of 95.5338 shares of our common stock per $1,000 
principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $10.47 per 
share of our common stock. The Convertible Notes are convertible at the option of the holders at any time prior to the close 
of business on the business day immediately preceding February 15, 2026, only under the following circumstances:
•
During any calendar quarter (and only during such calendar quarter), if the last reported sale 
price of our common stock for at least 20 trading days (whether or not consecutive) during 
a period of 30 consecutive trading days ending on, and including, the last trading day of the 
immediately preceding calendar quarter is greater than or equal to 130% of the conversion 
price on each applicable trading day;
•
During the five business day period after any ten consecutive trading day period (the 
“measurement period”), in which the “trading price” (as defined in the indenture governing 
the Convertible Notes) per $1,000 principal amount of the Convertible Notes for each 
95

trading day of the measurement period was less than 98% of the product of the last reported 
sale price of our common stock and the conversion rate on each such trading day;
•
If we call such Convertible Notes for redemption, at any time prior to the close of business 
on the scheduled trading day immediately preceding the redemption date; or
•
Upon the occurrence of specified corporate events as set forth in the indenture governing 
the Convertible Notes.
On or after February 15, 2026, until the close of business on the second scheduled trading day immediately 
preceding the maturity date, holders of the Convertible Notes may convert all or any portion of their Convertible Notes 
regardless of the foregoing circumstances. 
Since we have the election of repaying the Convertible Notes in cash, shares of our common stock, or a 
combination of both, we continued to classify the Convertible Notes as long-term debt on the consolidated balance sheets 
as of December 31, 2024.
We may redeem for cash all or any portion of the Convertible Notes (subject to the partial redemption 
limitation described in the indenture governing the Convertible Notes), at our option, on or after May 20, 2024 and prior to 
the 31st scheduled trading day immediately preceding the maturity date, if the last reported sale price of our common stock 
has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during 
any 30 consecutive trading day period (including the last trading day of such period) ending on the trading day immediately 
preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount 
of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. 
If we undergo a fundamental change (as set forth in the indenture governing the Convertible Notes), 
noteholders may require us to repurchase for cash all or any portion of their Convertible Notes at a repurchase price equal 
to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the 
fundamental change repurchase date. In addition, following certain corporate events (as set forth in the indenture governing 
the Convertible Notes) or if we deliver a notice of redemption prior to the maturity date, we will, in certain circumstances, 
adjust the conversion rate for a noteholder who elects to convert its notes in connection with such a corporate event or such 
notice of redemption. 
We accounted for the Convertible Notes as a single liability in accordance with ASU 2020-06 - Accounting 
for Convertible Instruments and Contracts in an Entity's Own Equity (“ASU 2020-06”). As of December 31, 2024, the 
Convertible Notes were recorded at the aggregate principal amount of $225.5 million less unamortized issuance costs of 
$1.6 million as a long-term liability on the consolidated balance sheets. As of December 31, 2024, the fair value of the 
Convertible Notes was $295.5 million. The fair value was estimated using a reputable third-party valuation model based on 
observable inputs and is considered Level 2 in the fair value hierarchy. The debt issuance costs are amortized to interest 
expense over the contractual term of the Convertible Notes at an effective interest rate of 3.1%.

Capped Calls
In connection with the issuance of the Convertible Notes, we entered into capped call transactions with one 
of the initial purchasers of the Convertible Notes and other financial institutions, totaling $27.2 million (the “Capped 
Calls”). The Capped Calls cover, subject to customary adjustments, the number of shares of our common stock that initially 
underlie the Convertible Notes (or 21,542,871 shares of our common stock). The Capped Calls have an initial strike price 
and an initial cap price of $10.47 per share and $15.80 per share, respectively, subject to certain adjustments. Conditions 
that cause adjustments to the initial strike price of the Capped Calls mirror conditions that result in corresponding 
adjustments to the conversion price of the Convertible Notes. The Capped Calls are expected to offset the potential dilution 
to our common stock as a result of any conversion of the Convertible Notes, subject to a cap based on the cap price.
96

For accounting purposes, the Capped Calls are considered separate financial instruments and not part of the 
Convertible Notes. As the Capped Calls transactions meet certain accounting criteria, we recorded the cost of the Capped 
Calls, totaling $27.2 million, as a reduction to additional paid-in capital within the consolidated statements of stockholders’ 
equity.

13.                    Net Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing net income (loss) attributable to common 
stockholders by the weighted-average number of shares of our common stock outstanding.
98

For the calculation of diluted net income per share, net income attributable to common stockholders for 
basic net income per share is adjusted by the effect of dilutive securities, including awards under our equity compensation 
plans and change in fair value of warrant liability. Diluted net income per share attributable to common stockholders is 
computed by dividing the resulting net income attributable to common stockholders by the weighted-average number of 
fully diluted common shares outstanding.
The numerators and denominators of the basic net income (loss) and diluted net income per share 
computations for our common stock are calculated as follows (in thousands):

Common Stock Outstanding
As of December 31, 2024, there were 125,449,558 shares of our common stock outstanding.
We entered into an at-the-market Sales Agreement with Cowen and Company, LLC (“Cowen”) on 
August 6, 2020 and an amendment to such agreement on August 3, 2023 (the sales agreement as amended, the “ATM 
99

Agreement”). Under the ATM Agreement, we may offer and sell from time to time, at our sole discretion, shares of our 
common stock having an aggregate offering price of up to $120.0 million through Cowen as our sales agent. We agreed to 
pay Cowen a commission of up to 3% of the gross sales proceeds of any common stock sold through Cowen under the 
ATM Agreement. As of December 31, 2024, we had approximately $120.0 million remaining under the ATM Agreement.
Share Repurchase Program
In November 2024, our Board of Directors authorized a share repurchase program (the “Program”) 
allowing us to repurchase up to $200.0 million of our common stock. On November 8, 2024, we entered into an accelerated 
share repurchase agreement (the "ASR Agreement") with Goldman Sachs & Co. LLC ("Goldman") to repurchase an 
aggregate amount of $100.0 million of our common stock. Under the ASR agreement, we made an aggregate upfront 
payment of $100.0 million to Goldman and received an aggregate initial delivery of 6,149,116 shares of our common stock 
on November 12, 2024, representing approximately 80% of the total shares that would be repurchased under the ASR 
Agreement measured based on the closing price of our common stock on November 8, 2024. 
The final number of shares that we ultimately repurchased pursuant to the ASR Agreement will be based on 
the average of the daily volume-weighted average ("VWAP") price per share of our common stock during the repurchase 
period, subject to adjustments pursuant to the terms and conditions of the ASR Agreement. The accelerated share 
repurchase terminated in February 2025. As of December 31, 2024, $100.0 million remained available for future 
repurchases under the Program.
Shares of our common stock repurchased under the ASR Agreement are immediately retired upon receipt 
and returned to authorized and unissued status. Repurchased common stock is reflected as a reduction of stockholders’ 
equity. Any excess of cost over par value is charged to additional paid-in capital to the extent that a balance is present. 
Once additional paid-in capital is fully depleted, any remaining excess of cost over par value is charged to accumulated 
deficit.
Warrants
During the year ended December 31, 2022, all of the 1,882,600 outstanding warrants as of December 31, 
2021 were exercised or expired, resulting in cash proceeds totaling $8.5 million. For the year ended December 31, 2022, 
we recognized the decrease in the estimated fair value of warrant liability of $1.8 million as income in other income 
(expense) in our consolidated statements of operations.
15.                    Equity Plans and Stock-Based Compensation
Equity Plans 
In January 2021, we adopted the Dynavax Technologies Corporation 2021 Inducement Award Plan (“2021 
Inducement Plan”), pursuant to which we reserved 1,500,000 shares of common stock for issuance under the plan to be 
used exclusively for grants of awards to individuals who were not previously our employees or directors. In June 2021, we 
amended the 2021 Inducement Plan (“Amended 2021 Inducement Plan”) to increase the number of shares of common 
stock reserved under the 2021 Inducement Plan to 3,250,000. The Amended 2021 Inducement Plan was terminated 
effective as of April 3, 2022 and, therefore, there are no shares of our common stock available for grant.
In May 2024, our stockholders approved the amendment and restatement of our 2018 Equity Incentive Plan 
(the “Amended 2018 EIP”) to, among other things, increase the authorized number of shares of common stock by 
11,400,000. The maximum number of shares of common stock that may be issued under the Amended 2018 EIP, will not 
exceed 41,440,250 shares of common stock. As of December 31, 2024, the Amended 2018 EIP and the Amended and 
Restated 2014 Employee Stock Purchase Plan are our active plans (the "Plans"). 
The Amended 2018 EIP is administered by our Board of Directors, or a designated committee of the Board 
of Directors, and awards granted under the Amended 2018 EIP have a term of 7 years unless earlier terminated by the 
Board of Directors. As of December 31, 2024, there were 14,122,413 shares of common stock reserved for issuance under 
the Amended 2018 EIP.
Under our Amended 2018 EIP, we may grant stock options, RSUs, performance-based awards, and other 
awards that are settled in shares of our common stock. Our equity awards generally vest over a three-year period contingent 
upon continuous service and unless exercised, expire seven or ten years from the date of grant (or earlier upon termination 
of continuous service). Activity under our stock plans is set forth below:

Performance-based Options
As of December 31, 2024, approximately 36,000 shares underlying performance-based options were 
outstanding.
Significant Assumptions in Estimating Option Fair Value
The fair value of each time-based option is estimated on the date of grant using the Black-Scholes option 
valuation model. The fair value of each RSU is determined at the date of grant using our closing stock price. The fair value 
of each PSU is estimated using the Monte Carlo simulation method on the date of grant. The weighted-average 
assumptions used in the calculations of these fair value measurements are as follows:

Expected volatility is based on historical volatility of our stock price. The expected life of options granted 
is estimated based on historical option exercise and employee termination data. Our senior management, who hold a 
majority of the options outstanding, and other employees were grouped and considered separately for valuation purposes. 
The risk-free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at 
the time of grant. Forfeiture estimates are based on historical employee turnover. The dividend yield is zero for all years 
and is based on our history and expectation of dividend payouts. 
Stock-based Compensation
Compensation expense is based on awards ultimately expected to vest and reflects estimated forfeitures. 
For equity awards with time-based vesting, the fair value is amortized to expense on a straight-line basis over the vesting 
periods. 
We have also granted performance-based equity awards to certain of our employees. For equity awards 
with performance-based vesting criteria, the fair value is amortized to expense when the achievement of the vesting criteria 
becomes probable.

As of December 31, 2024, the total unrecognized compensation cost related to non-vested stock options 
and RSUs deemed probable of vesting, including all stock options with time-based vesting, net of estimated forfeitures, 
amounted to $50.0 million, which is expected to be recognized over the remaining weighted-average vesting period of 1.7 
years. As of December 31, 2024, the total unrecognized compensation cost related to PSUs amounted to $9.2 million.
Employee Stock Purchase Plan 
The Amended and Restated 2014 Employee Stock Purchase Plan (the “Employee Stock Purchase Plan”) 
provides for the purchase of common stock by eligible employees. In May 2021, our stockholders approved the amendment 
and restatement of the Employee Stock Purchase Plan to increase the authorized number of shares of common stock by 
1,000,000. The maximum number of shares of common stock that may be issued under the Employee Stock Purchase Plan 
will not exceed 1,850,000 shares of common stock.
The purchase price per share is the lesser of (i) 85% of the fair market value of the common stock on the 
commencement of the two-year offer period (generally, the sixteenth day in February or August) or (ii) 85% of the fair 
market value of the common stock on the exercise date, which is the last day of a purchase period (generally, the fifteenth 
day in February or August). For the year ended December 31, 2024, employees have acquired approximately 184,000 
shares of our common stock under the Employee Stock Purchase Plan and approximately 538,000 shares of our common 
stock remained available for future purchases under the Employee Stock Purchase Plan. 
As of December 31, 2024, the total unrecognized compensation cost related to shares of our common stock 
under the Employee Stock Purchase Plan amounted to $0.4 million, which is expected to be recognized over the remaining 
weighted-average vesting period of 1.4 years.
16.                    Employee Benefit Plan 
We maintain a 401(k) Plan, which qualifies as a deferred salary arrangement under Section 401(k) of the 
Internal Revenue Code. Under the 401(k) Plan, participating employees may defer a portion of their pretax earnings. We 
may, at our discretion, contribute for the benefit of eligible employees. Our contribution to the 401(k) Plan was 
approximately $1.8 million, $1.3 million and $0.9 million for the years ended December 31, 2024, 2023 and 2022, 
respectively.

The tax benefit of net operating losses, temporary differences and credit carryforwards is required to be 
recorded as an asset to the extent that management assesses that realization is "more likely than not." Realization of the 
future tax benefits is dependent on our ability to generate sufficient taxable income within the carryforward period. A high 
degree of judgment is required to determine if, and the extent to which, valuation allowances should be recorded against 
deferred tax assets. In making such determination, we consider all available positive and negative evidence, including 
future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and 
recent financial operations. Based on all available evidence as of December 31, 2024, both positive and negative, and the 
weight of that evidence to the extent such evidence can be objectively verified, management believes that recognition of 
the deferred tax assets arising from the above-mentioned future tax benefits is currently not more likely than not to be 
realized, and, accordingly, has provided a valuation allowance.
The valuation allowance decreased by $7.9 million during the year ended December 31, 2024 and increased 
by $1.5 million during the year ended December 31, 2023. The increase in valuation allowance during the year ended 
December 31, 2024 was due to a decrease in our deferred tax assets, predominantly related to utilization of net operating 
losses and research and development credits offset by Section 174 capitalization and increased reserves. The increase in 
valuation allowance during the year ended December 31, 2023 was due to an increase in our deferred tax assets, 
predominantly related to Section 174 capitalization and increased reserves offset largely by utilization of net operating 
losses. 
As of December 31, 2024, we had federal net operating loss carryforwards of approximately $0.4 million, 
which began to expire in the year 2025, federal net operating loss carryforwards of approximately $293.1 million, which do 
not expire and federal research and development tax credits of approximately $26.5 million, which expire in the years 2025 
through 2044. 
As of December 31, 2024, we had net operating loss carryforwards for California and other states for 
income tax purposes of approximately $262.9 million, which expire in the years 2025 through 2041, and California state 
research and development tax credits of approximately $21.8 million, which do not expire.
As of December 31, 2024, we had no remaining net operating loss carryforwards for foreign income tax 
purposes.

Uncertain Income Tax positions
The total amount of unrecognized tax benefits was $12.4 million and $12.1 million as of December 31, 
2024 and 2023, respectively. If recognized, none of the unrecognized tax benefits would affect the effective tax rate.

Our policy is to account for interest and penalties as income tax expense. As of December 31, 2024, there 
were no interest and no material penalties recognized in the provision for income taxes. As of December 31, 2023, there 
were no interest and no penalties recognized in the provision for income taxes. We do not anticipate any significant change 
within 12 months of this reporting date of its uncertain tax positions.
The Tax Reform Act of 1986 limits the annual use of net operating loss and tax credit carryforwards in 
certain situations where changes occur in stock ownership of a company. In the event there is a change in ownership, as 
defined, the annual utilization of such carryforwards could be limited. For the year ended December 31, 2021, we 
completed a preliminary analysis under Section 382 of the Internal Revenue Code indicating we experienced ownership 
changes in 2008, 2010, 2012, and 2019 that limited the future use of our pre-change federal and state net operating loss 
carryforwards and federal research and development tax credits. We finalized the study during the year ended 
December 31, 2022 and concluded that we only experienced ownership changes in 2008, 2010, and 2012, resulting in a 
significant reduction in the federal and state net operating loss carryforwards and federal research and development tax 
credits that are expected to expire unused. We have revised the net operating loss carryforwards and research and 
development tax credits that are expected to expire unused as a result of the annual limitations in the deferred tax assets and 
corresponding uncertain tax positions as of December 31, 2022. There were no changes to our Section 382 analysis as of 
December 31, 2024.
We are subject to income tax examinations for U.S. federal and state income taxes from 2001 forward. We 
are subject to tax examination in Germany from 2020 forward, in India from 2021 forward and in Italy from 2021 forward.

ITEM 9A. CONTROLS AND PROCEDURES
(a) Evaluation of Disclosure Controls and Procedures 
We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the 
Securities Exchange Act of 1934 (“the Exchange Act”)) that are designed to ensure that information required to be 
disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in 
the Securities and Exchange Commission rules and forms and that such information is accumulated and communicated to 
our management, including our Principal Executive Officer and Principal Financial Officer, as appropriate, to allow for 
timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, 
management recognizes that any controls and procedures, no matter how well designed and operated, can only provide 
reasonable, not absolute, assurance of achieving the desired control objectives. 
Based on their evaluation of the effectiveness of the design and operation of our disclosure controls and 
procedures as of the end of the period covered by this report, our management, with the participation of our Principal 
Executive Officer and our Principal Financial Officer, concluded that our disclosure controls and procedures are effective 
and were operating at the reasonable assurance level to ensure that information required to be disclosed by us in reports that 
we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods 
specified in the Securities and Exchange Commission rules and forms. 
(b)Management’s Annual Report on Internal Control Over Financial Reporting 
Our management is responsible for establishing and maintaining adequate internal control over financial 
reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our management, with the participation of 
our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our internal 
control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (2013 Framework). Based on that evaluation, our management 
concluded that our internal control over financial reporting was effective as of December 31, 2024. Our independent 
registered public accountants, Ernst & Young LLP, audited the consolidated financial statements included in this Annual 
Report on Form 10-K and have issued a report on our internal control over financial reporting. The report on the audit of 
internal control over financial reporting appears below.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Dynavax Technologies Corporation
Opinion on Internal Control Over Financial Reporting
We have audited Dynavax Technologies Corporation’s internal control over financial reporting as of December 31, 2024, 
based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Dynavax Technologies 
Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2024, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related 
consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the 
three years in the period ended December 31, 2024 and the related notes and our report dated February 20, 2025 expressed 
an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s 
Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s 
internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform 
the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in 
all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, 
and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides 
a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and 
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded 
as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and 
that receipts and expenditures of the company are being made only in accordance with authorizations of management and 
directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Resolution of Class Action Law Suit 
As previously disclosed, on October 28, 2024, our Board of Directors (the “Board”) adopted a limited-
duration stockholder rights plan (the “Rights Agreement”).
On November 26, 2024, plaintiff Terry Ignasiak (the “Plaintiff”) filed a putative class action complaint (the 
“Complaint”) in the Court of Chancery of the State of Delaware (the “Court”) against the Company and the Board under 
the caption Ignasiak v. Dynavax Technologies Corporation et al., C.A. No. 2023-1219-JTL (the “Action”). The Action 
alleged, among other things, that Section 28 of the Rights Agreement improperly eliminated all liability of the Board for 
any action conducted in connection with the Rights Agreement.
After the Complaint was filed, on December 26, 2024, we entered into Amendment No. 1 (the 
“Amendment”) to the Rights Agreement. The Amendment removed and replaced Section 28 of the Rights Agreement 
making certain technical amendments to the rights and obligations of the Board to administer and make determinations 
with respect to the Rights Agreement and the rights issued thereunder. In particular, the Amendment confirms that nothing 
in the Rights Agreement, express or implied, including any provision requiring or permitting the Board to take (or refrain 
from taking) any action or making any determination shall be deemed to limit or eliminate the fiduciary duties of the Board 
under applicable law. The Rights Agreement otherwise remains unmodified and in full force and effect in accordance with 
its terms.
The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety 
by reference to the complete text of the Amendment, a copy of which we filed with the U.S. Securities and Exchange 
Commission (the “SEC”) on December 27, 2024 as Exhibit 4.1 to a Current Report on Form 8-K.
The Company denies and continues to deny all allegations of wrongdoing in the Action. We and the 
Plaintiff agreed that the Amendment and our actions related to the Amendment rendered Plaintiff’s claims moot. We also 
subsequently agreed to pay $155,000 in attorneys’ fees and reimbursement of expenses (the “Mootness Fee,” inclusive of a 
109

$500 service award to Plaintiff) in full satisfaction of any and all claims by Plaintiff and his counsel for fees and expenses 
in the Action. The Court has not and will not pass judgment on the amount of the Mootness Fee.
On February 17, 2025, the Court entered an order closing the Action, subject to us filing an affidavit with 
the Court confirming that these disclosures in this Annual Report on Form 10-K, which shall constitute notice to the 
putative class for purposes of Delaware Court of Chancery Rule 23, have been filed with the SEC.
