The Home Depot Inc. had a good second quarter, but its performance really hit home with sales to its business “Pro” customers.

Total sales in the second quarter ended June 30 increased 6.5% year over year to $43.8 billion, as net earnings increased 8.3% to $5.2 billion.

“In the second quarter, we delivered the highest quarterly sales and earnings in our company’s history,” president and CEO Ted Decker said on a Q2 earnings call, according to a transcript from The Motley Fool. But sales through the retailer’s digital channels grew at almost twice that rate, increasing 12%, he added.
