What: Shares of Lumber Liquidators Holdings (LL 0.87%) rose more than 15% in Wednesday's early trading, then settled to trade up around 9.5% as of 1:30 p.m. after the hardwood flooring retailer announced weaker-than-expected third-quarter results, but also appointed a promising new CEO.

So what: Regarding the former, third-quarter revenue fell 11.3% year over year to $236.1 million. Thanks primarily to allegations in a critical 60 Minutes report that Lumber Liquidators sold laminate flooring sourced from China containing illegally high levels of formaldehyde, those results included a 14.6% comparable-store sales decline, which itself was comprised of a 13% drop in the number of customers invoiced, and a 1.6% decrease in each average sale. To a lesser extent, Lumber Liquidators believes sales were also hurt by stronger competition, its decision to suspend sales of all laminate flooring sourced from China, and the disruption of supply for certain engineered hardwood vendors.  On the bottom line, that translated to a net loss of $8.5 million, or $0.31 per diluted share, compared to net income of $0.58 per share in the year-ago period.

Analysts, on average, were expecting Lumber Liquidators to report a narrower loss of $0.18 per share on higher revenue of $259.8 million.

For perspective on the latter, keep in mind Lumber Liquidators stock plunged in May after the company announced the unexpected resignation of then-CEO Robert Lynch. Though to be fair, Lynch's departure did follow the critical 60 Minutes report two months earlier. At the time, Lumber Liquidators appointed company founder Thomas Sullivan as acting CEO as it searched for a permanent replacement.

Today, however, Lumber Liquidators has found that replacement in John Presley, who most recently served as independent chairman of the board and head of Lumber Liquidators' special committee formed to review the underlying certification and labeling processes of its suppliers. Presley had served as CEO of First Capital Bancorp and also joined Lumber Liquidators as a director in early 2006, well before the company's IPO in late 2007.

Presley added:

I am honored to have been chosen to lead Lumber Liquidators forward.  Lumber Liquidators has a unique value proposition of delivering the best hardwood flooring selection, prices and expertise.  Over the years I have come to see just how committed our employees are -- and I know that together, we have the drive and the vision to succeed and enter the next chapter of our Company's exciting future as we execute our turnaround.  As CEO, I am committed to strengthening Lumber Liquidators across every area of the organization and improving our performance.

Now what: With shares still down more than 70% so far in 2015, I can't blame investors for being excited by the prospect of an experienced leader in Presley managing Lumber Liqiudators' turnaround. But we should also keep in mind the company has plenty of work to do before it's out of the woods, most notably including finding resolution to potential regulatory action from the California Air Resources Board from an ongoing investigation of its products.

That's part of the reason Lumber Liquidators isn't providing specific fourth-quarter 2015 guidance. But also to its credit, it did tell investors by the end of 2015, it will have opened a total of 23 to 24 new store locations in its expanded showroom format (near the high end of previous guidance for 20 to 25 new stores), remodeled a total of 12 existing stores in that format (narrowed from 10 to 15 existing store remodels previously), and have capital expenditures between $22 million and $25 million (a $2 million increase to the bottom end of the prior range). 

In the end, though, I prefer to watch Lumber Liquidators from the sidelines until it finds a complete resolution to outstanding regulatory action. While this might result in missing out on some near-term speculative gains, the risk of an extended slide in sales or a negative surprise from that regulatory action is too great for my investing taste.
