Lumber Liquidators, facing U.S. government probes over claims of dangerous levels of a cancer-causing substance in its flooring products, stood by the safety of its products and said it would offer free indoor air quality testing for qualifying customers.
The hardwood flooring retailer's stock was up 4.5 percent at $34.20 in volatile premarket trading on Thursday.
The stock had halved since Feb. 25 when the company said CBS's "60 Minutes" show would portray Lumber Liquidators in an "unfavorable light with regard to sourcing and product quality."
The CBS show, aired on March 1, alleged Lumber Liquidators' flooring had higher-than-permitted levels of formaldehyde, a known carcinogen.
Customers would get the same quality testing kits used in workplaces and the tests would be carried out by a third party, the retailer said on Thursday in slides slated to be used later on a conference call to assuage investors' concerns.
