Credit & convertible securities analyst

GigaMedia extends a US$7M Aeolus convertible note on fixed 4% terms.

The amendment keeps GigaMedia’s exposure to the Aeolus Robotics convertible note at US$7 million with a 4% annual interest rate, pushing maturity to May 31, 2026. This preserves both interest income and potential upside from equity conversion tied to future Aeolus financing milestones.

Conversion is allowed at the lower of US$1.25 per share or 80% of the offering price at maturity, prepayment, certain events, the next equity round, or an IPO. Actual impact depends on Aeolus’s ability to complete financings or an offering on favorable terms.

The amendment is described as supporting Aeolus’s recent financing activities, and GigaMedia notes it may enter further Aeolus securities transactions subject to law. Future company filings would clarify outcomes if Aeolus completes equity financings or an initial public offering that trigger conversion.
