Adjuvanted Hepatitis B vaccine (Recombinant)(Dynavax Technologies Corp.)

Dynavax's Strategy is Delivering Significant Long-Term Stockholder Value Dynavax's Nominees Are Vastly Superior to Deep Track's Candidates Across Every Critical Area Follow Recommendations of Proxy Advisory Firms ISS and Egan-Jones and Vote "FOR" All Four of Dynavax's Director Nominees on the GOLD Proxy Card Today EMERYVILLE, Calif., June 9, 2025 /PRNewswire/ -- Dynavax Technologies Corporation (Nasdaq: DVAX) ("Dynavax" or the "Company"), a commercial-stage biopharmaceutical company developing and commercializing innovative vaccines, today issued the following statement reiterating to stockholders its recommendation to vote "FOR" all four of Dynavax's highly qualified directors standing for election – Brent MacGregor, Scott Myers, Lauren Silvernail and Elaine Sun – at the Company's upcoming Annual Meeting of Stockholders on June 11, 2025 (the "2025 Annual Meeting"). Since 2019, Dynavax has successfully executed a strategic repositioning of our business, and our refreshed Board is executing a plan that is delivering significant stockholder value. In direct contrast, Deep Track – which has no experience developing and executing corporate strategy, operations, or finance – is insistent on implementing its strip-mining plan for Dynavax, jeopardizing a strong platform with significant long-term growth opportunities for a near-term payoff of a considerably lower value. Simply put: there is no case for change, and changing course to Deep Track's purported plan will destroy long-term value and is not in the best interests of all stockholders. Re-electing all four of our nominees is essential to our ability to continue driving value for all stockholders. Without Brent MacGregor, Scott Myers, Lauren Silvernail and Elaine Sun, the Board would be deprived of essential strategic leadership, vaccine expertise, senior public biotechnology and M&A experience, as well as deep industry financial expertise – qualifications that none of Deep Track's candidates can adequately match. Deep Track's principal, Brett Erkman, is beholden to his own hedge fund investors – not our stockholders – and has demonstrated an inability to be open-minded. Donald Santel lacks vaccine industry experience and his public company executive experience ended ten years ago. In short, Deep Track's nominees are far less qualified than all of our current directors. Make no mistake – Deep Track is attempting to gain control of Dynavax to implement its flawed plan, which would be detrimental to the long-term value we are generating for our stockholders. Independent proxy advisory firms Institutional Shareholder Services ("ISS") and Egan-Jones agree and recommend that stockholders support all of Dynavax's director nominees. ISS noted that Deep Track has failed to present a compelling case for change and called attention to Deep Track's cherry picked and highly misleading materials throughout its campaign – "There are serious concerns with the dissident's presentation of TSR…The dissident's attempt to suggest otherwise through a blatantly distorted TSR analysis has only diminished its credibility."1 Glass, Lewis & Co. ("Glass Lewis") acknowledged the significant stockholder returns we have been generating, our differentiated capital allocation plan, and the meaningful refreshment and high caliber Board we have in place. Perhaps most importantly, Glass Lewis put a fine point on the legitimate concerns stockholders should have in electing Mr. Erkman to the Board – noting that "his fiduciary experience in a boardroom setting remains untested" and "may raise legitimate questions about Mr. Erkman's ability to balance Deep Track's position with the broader interests of all shareholders."2 Here's why we encourage you to vote for ALL four of Dynavax's nominees: The strategy Dynavax has in place, and is successfully executing against, is working. We positioned HEPLISAV-B® to be the market-leading hepatitis B vaccine, and are consistently delivering record financial results, including most recently a few weeks ago when we reported Q1 2025 results, and have delivered 203% total return to stockholders over the last five years3. We are far outperforming vaccine peers, which have returned 9%, and the S&P Biotechnology Select Industry Index, which has declined 17%. This is the result of consistent operational execution, skilled business development which generated over $950 million in revenue between 2020 and 2022, and a disciplined capital allocation plan that, as of May 5, 2025, included execution of over 85% of the $200 million share repurchase program authorized in November 2024. The directors Dynavax needs at this time are already on the Board. The Board has been thoughtfully reshaped in recent years with new, independent directors – following the Annual Meeting, the Board will be comprised of nine directors, with six of eight independent directors having been appointed since 2020 – who bring highly specialized skillsets that are directly aligned to our long-term strategic plan. Our directors, including those up for re-election, are renowned experts in their fields within biotech and vaccines across operations, finance/capital markets, business development M&A, commercialization, R&D, public health and more. Replacing any Dynavax directors with Deep Track's underqualified nominees would disrupt the momentum of our clearly successful long-term strategy and put stockholder value at risk. With our 2025 Annual Meeting fast approaching on June 11, it is extremely important that you vote as soon as possible, no matter how many shares you own. We urge you to vote "FOR" all four of Dynavax's director nominees – Brent MacGregor, Scott Myers, Lauren Silvernail and Elaine Sun – on the GOLD proxy card today.

Dynavax is Already Delivering Significant Long Term Stockholder Value Through Execution of Current Strategy Overseen by Board; Deep Track's Inferior Short-Term Plan and Nominees are Not in the Best Interests of All Stockholders Glass Lewis' Recommendation Recognizes the Significant Stockholder Value Creation and Differentiated Capital Return Overseen by the Dynavax Board Reiterates ISS and Egan Jones Recommendations that Stockholders Support ALL Dynavax Nominees and Deep Track Board Representation is Not Warranted Urges Stockholders to Vote "FOR" ALL Four of Dynavax's Highly Qualified Director Nominees on the GOLD Proxy Card Today EMERYVILLE, Calif., June 4, 2025 /PRNewswire/ -- Dynavax Technologies Corporation (Nasdaq: DVAX) ("Dynavax" or the "Company"), a commercial-stage biopharmaceutical company developing and commercializing innovative vaccines, today commented on a report published by Glass, Lewis & Co. ("Glass Lewis") in connection with the election of the Company's director nominees – Brent MacGregor, Scott Myers, Lauren Silvernail and Elaine Sun – at its Annual Meeting of Stockholders on June 11, 2025 (the "2025 Annual Meeting"): We strongly disagree with Glass Lewis' recommendation against two of our highly qualified directors. Significant Board composition and strategy changes have already been made, and the directors needed to continue successfully executing our superior strategic plan that is delivering significant long-term stockholder value are already on the Board. Indeed, Glass Lewis acknowledges that Dynavax's 2019 pivot has generated significant stockholder returns, the Company's share repurchase program differentiates Dynavax amongst our peers, and our Board has been meaningfully refreshed with high-quality and sector-specific expertise. In its June 4, 2025, report, Glass Lewis noted1: "Dynavax's longer-term performance suggest that its 2019 strategic pivot toward vaccines has meaningfully contributed to shareholder value creation." "We also observe that the board has a relatively balanced mix of short-, medium- and long-tenured directors: two directors (including Management Nominee Silvernail) were appointed in February 2025; four (including Management Nominees MacGregor, Myers and Sun) were appointed between 2020 and 2021, more than a year after the Company had announced its strategic pivot to focus on its vaccine business; and three have served since the pre-2019 strategic pivot." "We recognize that each of the Company's directors have C-suite experience within the healthcare sector. To be clear, we do not doubt the depth, quality and relevance of the sector-specific expertise offered by these directors." Importantly, Institutional Shareholder Services ("ISS") and Egan Jones agree that there is not a case for change and stockholders should support all of Dynavax's director nominees. Dynavax has the right strategy and the right Board: Growing HEPLISAV-B® market leadership: Since its launch in 2019, the Board and management team have grown HEPLISAV-B® to be the market-leading hepatitis B vaccine with $268 million of net product revenue in 2024 and 44% market share as of year-end 2024, quickly overtaking the large pharma incumbent market leader of the U.S. adult hepatitis B vaccine market. The Company continues to deliver record operational and financial results, including record first quarter 2025 financial results with HEPLISAV-B® net product revenue of $65 million, a 36% increase year-over-year, and total revenue of $68.2 million, 34% increase year-over-year. Clear strategic plan that is delivering superior stockholder value: The Company is executing a clear go-forward capital allocation strategy that balances strategic investment in growth through pursuit of internal and external assets and opportunistically returning capital to stockholders. This plan is clearly working as Dynavax has delivered 203% total return to stockholders over the last five years2 while vaccine peers returned 9% and the S&P Biotechnology Select Industry Index declined 17% over the same period. Dynavax is one of the few vaccine companies that has returned meaningful capital to stockholders: As of May 5, 2025, the Company has executed over 85% of its $200 million share repurchase program authorized in November 2024. The $200 million share repurchase program represents 47%3 of Dynavax's use of capital, far in excess of its peers. Proactive, strategic and extensive Board refreshment: Following the 2025 Annual Meeting, the Board will be comprised of nine directors, with six of eight independent directors having been appointed since 2020. Strengthened accountability and oversight: Through a phased board declassification. All of our nominees – Brent MacGregor, Scott Myers, Lauren Silvernail and Elaine Sun – are vastly superior to Deep Track's slate, and replacing any of them would leave Dynavax deficient in vital expertise that is needed to guide the Company through a pivotal year. They have expertise across every facet of the biotechnology and vaccine spaces and have led multiple company transactions generating billions of dollars and maximizing stockholder value. In particular, the loss of Mr. MacGregor, a member of our Nominating and Corporate Governance Committee who has helped oversee the Company's proactive refreshment program and brings critical vaccine development and commercialization expertise, or Mr. Myers, the Chairman of our Board who brings decades of public company leadership experience, would be detrimental to long-term stockholders. Deep Track's candidates lack the decades of public company biotechnology and vaccine operational and financial acumen that Dynavax's directors bring and have little to no public company board experience. In discussing the redundant skills of Deep Track's independent candidates, Glass Lewis noted, "However, we note that these functional areas – operations, commercialization, and C-suite leadership – are already represented to a meaningful degree on the current board." As Glass Lewis states, there are legitimate concerns with Brett Erkman's candidacy and background that stockholders should question. As a Deep Track fund principal, he is beholden to Deep Track's thesis and has repeatedly demonstrated his unwillingness to be open-minded. Further, he is underqualified to serve on our Board given he has never served as an executive at a biotech company or as a director of a public company nor served in an operational or financial role at any company. Glass Lewis noted, "Mr. Erkman's candidacy is not without potential drawbacks. He has no prior experience serving as a public company director or executive, and as such, his fiduciary experience in a boardroom setting remains untested. Moreover, while his affiliation with Deep Track underscores alignment with shareholders, his interview with the Company reportedly emphasized his firm belief that Dynavax's current capital allocation strategy should change – a stance that management characterized as rigidly aligned with Deep Track's views. This posture, along with the Company's consistent resistance to his appointment across multiple settlement discussions, may raise legitimate questions about his willingness or ability to balance Deep Track's position with the broader interests of all shareholders." It remains abundantly clear that Deep Track simply wants a near-term payoff, which would come at the expense of long-term value generation for all other stockholders.
