La-Z-Boy Inc. /zigman2/quotes/202858913/composite LZB +6.75% shares sank 10.2% in Thursday premarket trading after the furniture company reported an earnings miss, with tariffs taking a toll. La-Z-Boy's Casegoods segment had a 6.3% sales decline to $29.4 million, which the company attributed to "industry challenges," a merchandise delay from one supplier and the impact of tariffs on the table business. Sales for the e-commerce site Joybird rose 11.9% to $20.8 million, a lower-than-expected result, according to Raymond James, though analysts held on to their outperform rating based on the 3.5% same-store sales increase for the La-Z-Boy Furniture Galleries. KeyBanc Capital Markets isn't as bullish. "While the top-line opportunity for La-Z-Boy remains encouraging (supported by online brand Joybird and the new Kristen Bell marketing), we remain concerned about choppier end-market trends due to competition and uncertainty related to tariffs," analysts said. KeyBanc rates La-Z-Boy shares sector weight. La-Z-Boy stock has gained 30.6% for the year to date while the S&P 500 index /zigman2/quotes/210599714/realtime SPX +1.92% is up 24% for the period.
