San Diego-based Pulse Electronics reported late Tuesday that it has received a warning from the New York Stock Exchange, saying that the company is not in compliance with continued listing rules on the exchange. Pulse said that the company is below the NYSE minimum requirement for average total market capitalization over 30 consecutive trading days of greater than $50 million when its last reported shareholders' equity is less than $50 million. Pulse said it has 45 days to demonstrate the ability to achieve compliance within nine months of the notice. The warning is the first warning shot towards an eventual delisting, if it does not regain the NYSE standards. Pulse makes magnetic products, antennas, and connectors for the electronics industry.
