Lowe’s (NYSE:LOW) on Tuesday reported lower fiscal second-quarter results, although earnings topped Wall Street’s expectations and the home improvement retailer maintained its full-year outlook. Per-share earnings came in at $4.56 for the three months through Aug. 4, down from $4.67 the year before, but ahead of the Capital IQ-polled consensus of $4.48. Sales dropped to $24.96 billion from $27.48 billion, just shy of the Street’s view for $24.98 billion. The stock gained 2.9% in premarket trading. Sales included a roughly $335 million headwind related to a timing shift in the retailer’s fiscal calendar, as it cycled over a 53-week year, it said. Same-store sales declined 1.6%, compared with a 2.6% decrease modeled by analysts, as a robust spring recovery and sales traction in the company’s pro and online businesses helped partially offset lumber deflation and lower do-it-yourself discretionary demand. Selling, general and administrative expenses narrowed to $4.09 billion from $4.46
