What Happened
Soligenix, Inc. announced a Charter Amendment that increases its authorized common stock from 75,000,000 to 125,000,000 shares. The amendment was approved at the company’s 2026 annual meeting and became effective upon filing with the Delaware Secretary of State on September 17, 2026. The company also filed a prospectus supplement (June 26, 2026) increasing the capacity under its At Market Issuance Sales Agreement (dated January 23, 2026, with Rodman & Renshaw LLC) by an additional $2,500,000; a legal opinion regarding the $2.5M of shares is included as an exhibit.

• Prospectus supplement filed June 26, 2026 increased the maximum aggregate ATM offering by $2,500,000.
• The company previously sold approximately $6,234,000 of common stock under the Sales Agreement; prior prospectus coverage was up to $6,406,000.
• Sales Agreement counterparty: Rodman & Renshaw LLC (agreement dated January 23, 2026). Legal opinion filed as Exhibit 5.1; Certificate of Amendment filed as Exhibit 3.1.

Why It Matters
Increasing authorized shares gives Soligenix the legal capacity to issue more common stock in the future, which the company can use for financing, partnerships, or other corporate purposes. The expanded At Market (ATM) facility increases the company’s immediate ability to raise up to an additional $2.5M by selling shares into the market. For investors, these actions can provide cash-raising flexibility but also represent a potential source of future dilution if shares are issued.
