Wahlco Applies for Nasdaq Listing

Wahlco Environmental Systems Inc. said it has applied to have its common stock listed on the Nasdaq Bulletin Board, an unregulated electronic marketplace.

The Santa Ana company’s stock has been listed on the New York Stock Exchange, but trading was suspended last month because the company fell below listing requirements. The exchange said Wahlco has less than $12 million in net tangible assets available to common shares and less than $600,000 in average net income for the last three years.

Wahlco makes power generation and air pollution control equipment.
