Quote Factors to ConsiderPro customers have been a significant driver in Lowe's business growth. Moreover, in a bid to continue augmenting sales from pro customers, the company has been boosting pro-focused brands. Lowe’s has refurbished its pro-service business website, LowesForPros.com, in order to give special attention to the needs of its Pro-customers.Also, the company’s strong digital presence has been aiding its performance for a while. It achieved 16% comps growth on Lowes.com during the last reported quarter driven by robust traffic. Management’s focus on improving omni-channel capabilities, enhancing consumers’ digital shopping experience and inventory rationalizing, are likely to generate incremental sales. Lowe’s is also ramping up the amount of SKUs and assortments on lowes.com. Together, these upsides paint an impressive picture about Lowe’s top line in the quarter to be reported.However, margins will remain one of the key areas to watch this earnings season. We note that the metric shrunk around 160 basis points to 31.5% during the last reported quarter due to systems & process limitations and pricing issues, increased supply chain costs associated to new facilities along with higher transportation costs and customer deliveries, and adverse product mix shift.Nevertheless, the company is on track to undertake the necessary pricing and other actions to battle cost-related headwinds. It is to be seen how much it has succeeded on this front. Surely, any deleverage is likely to hurt the bottom line.What Our Model SaysOur proven model does not conclusively show that Lowe's is likely to beat bottom-line estimates this quarter.
