JELD-WEN Holding, Inc.’s shares fell as much as 9.8 percent post-market Thursday, after it announced preliminary third quarter results and lowered its forecast for the year.

The company now sees sales for the year down 2 percent, a cut from a view of flat sales JELD-WEN predicted in August. Shares were trading down as much as 9.3 percent Friday, the biggest drop in a year.

JELD-WEN also predicted third quarter net revenues of approximately $1.09 billion, a decrease of 3.9 percent compared to the same period last year. The company’s earnings before interest, tax, depreciation and amortization for the third quarter are expected to be between $106 million and $110 million, which is a decrease from the previous year’s $132.6 million.

The overall results were lower than expected for the North America and Australasia regions. The company said this can be attributed to a decline in demand for residential construction, as well as inconsistent order patterns for the windows retail channel in North America.

“I believe the issues that impacted our third quarter results underscore the urgency to continue to implement our strategy, reduce our cost structure, eliminate complexity in our operations, and increase agility throughout the organization,” said CEO Gary Michel.

The company will provide a full update to its 2019 financial metrics outlook during its scheduled call on Nov. 6.

JELD-WEN is one of the world’s largest door and window manufacturers, operating manufacturing facilities in 20 countries.

The company’s stock was trading at $16.84 Friday, down $1.73 per share.
