Thank you, and good morning to everyone. Sherwin-Williams delivered excellent first quarter results compared to the same period a year ago. Consolidated net sales grew by a high single-digit percentage, ahead of our expectations and were led by a mid-teens percentage increase in our professional architectural end markets. On the Industrial side of the business, sales increased in all regions except Asia Pacific.
Gross margin significantly improved sequentially and year-over-year, driven by strong volume in the Paint Stores Group and effective pricing. Cost of goods sold includes higher inflation in wages and other employee-related categories, which were partially offset by a slight decrease in year-over-year raw material costs. We expect to hold the majority of the pricing we have put into the market, given the ongoing investments we have made to drive innovation, enhance services and secure the talent that provides differentiated solutions to help our customers reach their goals and drive their success.
Segment margin in all three reportable segments expanded sequentially and year-over-year. We also delivered strong double-digit growth in diluted net income per share and EBITDA. Additionally, we continue to execute on the portfolio realignment actions we announced late last year, including the divestiture of a noncore aerosol business, which closed on April 1, and our recently announced agreement to divest our China architectural business.
