Dynavax Announces Convertible Debt Refinancing and Common Stock Share Repurchase

Dynavax Announces Convertible Debt Refinancing and Common Stock Share Repurchase

• Opportunistic refinancing extends the maturity of most of existing debt with improved terms and reduces dilution to existing capital structure
• $225 million of convertible notes due in 2030 issued, including an exchange for the retirement of ~$185 million of existing convertible notes due in 2026 and ~$40 million of new money
• Dynavax repurchased ~$8 million of the Company's common stock in connection with this transaction

EMERYVILLE, Calif., March 6, 2025 /PRNewswire/ -- Dynavax Technologies Corporation (Nasdaq: DVAX), a commercial-stage biopharmaceutical company developing and commercializing innovative vaccines, has entered into privately negotiated exchange and subscription agreements (the "Exchange Agreements") with a limited number of holders of its outstanding 2.50% Convertible Senior Notes due 2026 (the "2026 Notes") and one new investor, pursuant to which the Company will issue $225 million aggregate principal amount of 2.0% Convertible Senior Notes due 2030 (the "New Notes") comprised of (i) an exchange for the retirement of approximately $185 million in aggregate principal amount of existing 2026 Notes, and (ii) approximately $40 million of New Notes issued to existing holders and one new investor (the "Transactions").

The conversion price of the New Notes will initially be $18.21 per share of Dynavax's common stock, which represents a conversion premium of 30% over the closing price of Dynavax's common stock on March 5, 2025. Upon the completion of the Transactions, which is expected to occur on or about March 13, 2025, approximately $40 million in aggregate principal amount of the 2026 Notes will remain outstanding with terms unchanged, and the aggregate principal amount of the New Notes outstanding will be $225 million.

In connection with the Transactions, Dynavax entered into agreements with certain of the existing capped call counterparties to unwind a  portion of the existing capped call derivatives in a notional amount corresponding to the number of common shares underlying the 2026 Notes to be retired. Dynavax expects to receive approximately $46.5 million in connection with the unwind transactions, which it intends to use to partially offset the premium paid for the 2026 Notes in excess of par value and accrued and unpaid interest.

Additionally, the Company intends to repurchase approximately $8 million of the Company's common stock from certain participants in the Transactions through a financial intermediary at the closing price on March 5, 2025, to maintain a net neutral exchange of shares associated with the Transactions.

Kelly MacDonald, Chief Financial Officer of Dynavax said, "We continue to make progress across our strategic priorities, including strengthening our overall financial profile. This opportunistic refinancing accomplishes several of our liability management objectives in a highly efficient way by extending the maturity of a large portion of our existing debt, lowering overall cost of capital with meaningfully improved terms, reducing total shares underlying the 2026 Notes by nearly 25% and advantageously buying back approximately $8 million of the Company's common stock as part of these Transactions.  We believe these Transactions have resulted in a significantly strengthened capital structure, which helps position us to execute on our balanced strategy to deliver near-term value while also investing in our long-term growth."

Additional information regarding this announcement may be found in a Current Report on Form 8-K that Dynavax intends to file today with the U.S. Securities and Exchange Commission.
