• Public Offering Finalized

  Aura Biosciences finalized an underwritten public offering of 39,591,000 shares of common stock and 3,800,000 pre-funded warrants at $6.00 per share (or $5.99999 per warrant). This follows the proposed offering announced on May 4, 2026.

• Significant Capital Raise

  The offering is expected to generate approximately $244.7 million in gross proceeds, with net proceeds of $205.1 million after a stock repurchase and expenses. This capital infusion is crucial for extending the company's cash runway into the second half of 2028, addressing the "going concern" warning from its last annual report.

• Strategic Stock Repurchase

  The company will use $39.0 million of the net proceeds from this offering to repurchase 6,922,870 shares (approximately 10.8% of outstanding stock) from Matrix Capital Management Master Fund, LP at $5.64 per share, a discount to both the offering price and current market price.

• Substantial Dilution

  The offering, including warrants, represents a potential increase of approximately 57.35% in outstanding shares (net of the repurchase), indicating significant dilution for existing shareholders.

This 424B5 filing finalizes the terms and pricing of the public offering previously proposed on May 4, 2026. While the offering is highly dilutive and priced at a notable discount to the current market price, it is a critical financing event for Aura Biosciences, a company that had a "going concern" warning in its most recent annual report. The successful raise of over $205 million (net of repurchase) significantly extends the company's cash runway into the second half of 2028, providing essential capital for its clinical programs. The concurrent repurchase of a substantial 10.8% stake from Matrix Capital at a price below the offering price is a strategic move that partially mitigates the overall dilution and is a favorable transaction for the company. Investors should weigh the immediate dilution against the improved financial stability and extended operational timeline for its drug development.
