APTN Largest Shareholder Aprogen Increases Stake to 48% Amid 17.8% Dilutive Capital Increase and Convertible Bond Adjustments; Pledge of Shares Raises Governance Concerns
Aprogen Inc., the largest shareholder of APTN Inc., reported an increase in its total holding from 45.61% to 48.06% as of July 23, 2026, driven by a paid-in capital increase that expanded outstanding shares by 3.5 million or 17.8%, and by conversion price adjustments on convertible bonds held by related parties.
