Irvine-based drugmaker AtheroNova Inc.’s shares fell sharply Friday after it disclosed that it experienced “an event of default” on a $427,500 loan that triggered defaults on three others.
Shares of the development-stage heart drug maker were down 62% to a market value of $1.1 million after Friday’s market close. Markets are closed today for the President’s Day holiday.
AtheroNova said in a Securities and Exchange Commission filing that it received a debt acceleration notice from holder Europa International Inc., which is affiliated with company director Fred Knoll.
AtheroNova said the default triggered defaults on three other notes totaling about $3 million.
Separately, the company received a patent from the U.S. Patent and Trademark Office for “subcutaneous fat reduction.”
