Deep Track Capital Comments on ISS Recommendation

Deep Track Capital, LP, (together with its affiliates, “Deep Track” or “we”), one of the largest shareholders of Dynavax Technologies Corporation (NASDAQ: DVAX) (“Dynavax”, “DVAX” or the “Company”), with ownership of approximately 14.82% of the Company’s outstanding shares, today issued the following statement in response to a report issued by Institutional Shareholder Services Inc. (“ISS”) regarding the election of directors to the Company’s Board of Directors (the “Board”) at the 2025 Annual Meeting of Stockholders (the “Annual Meeting”).

“We firmly believe ISS reached the wrong conclusion by failing to recommend any amount of change in the Dynavax boardroom. The report reads as a rushed and incomplete assessment: not only does it mistakenly use the name of a completely different company at one point, but it also contains numerous factual errors and does not accurately capture key events. Critical issues are completely ignored, including Heplisav’s flattening market share growth, management missing performance targets set by the Board, and a shareholder-unfriendly approach to capital allocation. ISS fails to hold the Board to account even for issues it acknowledges in its report, such as the need for improved corporate governance. Above all else, we are disappointed that ISS readily adopted the Company’s view that a significant long-term shareholder would add no value to the Board.

We call shareholders’ attention to the following points:

• Recent failures demand a strategic pivot. Heplisav’s market share of 44% exiting 2024 failed to achieve the target of 47% set by the Board; similarly, annual sales also failed to achieve the $275 million goal.¹ This year is hardly off to a better start, with market share of only 43% for the first quarter of 2025. Yet Dynavax refuses to acknowledge this is a problem, with management stating just earlier this month that they were “very comfortable” with and “very proud” of this result and noted the strategy is going “exactly how we had planned.”² It is entirely unclear why ISS would completely ignore key performance metrics set by the Board as part of their evaluation, choosing instead to simply rubber stamp the Company’s arguments.

• ISS acknowledges that the Company has “a number of suboptimal corporate governance provisions”³ yet fails to take Dynavax to task for its half-hearted attempts to address these issues. ISS ignores the most glaring governance defect, which is the imbalanced classes of directors (with the classes split three, two and four) and with the classified Board structure not ending until 2028. Further, the addition of two new directors with no vaccine commercialization expertise while Heplisav’s market share has been stuck in the low 40 percent range for now seven consecutive quarters is, in our view, inexplicable. We proposed a candidate with over two decades of vaccine commercialization experience (who, contrary to what ISS wrote, was never offered a seat by the Board). Instead, ISS applied their rubber stamp to the director handpicked by the Chairman from his previous board role, who has served for all of three months and brings zero prior vaccine expertise to the table.

• Market reaction to first quarter 2025 results indicates widespread concerns, in our view. The Company’s share price fell 11% in reaction to the first quarter earnings report. In terms of broader strategy, ISS states that “the company has been sitting on a cash pile for several years, and shareholder patience may be waning” but then fails to consider our argument that excess cash could be best deployed by returning capital to shareholders. ISS appears to assert that the Board is unlikely to pursue a potentially destructive acquisition because it has not done so yet; while they may find comfort in this logic, we don’t think shareholders will take the same generous view.

• The Company’s total shareholder return (“TSR”) demonstrates clear underperformance. We question the relevance of DVAX performance dating back to 2019, given how few of the current Board members had anything to do with the Company at that time (and in fact, none of the nominees up for election this year). The Company extracted significant value from the pandemic, but as the CEO himself describes, that was a “once in a lifetime”⁴ experience, and attention should now shift to the present. Dynavax shares are down 23% year-to-date. The Company’s TSR declined by 43% between two milestone events: from the appointment of Scott Myers as Board Chair to our amended Schedule 13D filing that led the Board to adopt a poison pill.⁵ With respect to the benchmark that the Board uses to assess relative TSR for determining management’s compensation, the Nasdaq Biotech Index, DVAX shares underperformed by 40 percentage points.

• ISS’s report paints an inaccurate and incomplete picture of settlement discussions. Contrary to what ISS wrote, the Company never made an offer that included re-balancing its classes. Also, our final proposal included a two-year standstill, another item that ISS omits. Specifically, our final proposal was that Dynavax appoint Mr. Erkman and Mr. Santel to the Board, two incumbent directors step down, the share repurchase program be increased, and Deep Track would agree to a standstill until the nomination period for the 2027 annual meeting.

Shareholders should see through ISS’s surface-level analysis and consider the substantive issues at stake. Dynavax continues to underperform while the Board ignores its failed strategy. Our nominees possess exceptional relevant experience that could immediately improve the Board’s ability to assess the best path forward to maximize value. We urge shareholders to vote FOR our four highly qualified nominees.”
