Thank you, Brian. Good afternoon, everyone. We reported a solid quarter in Q1 with year-over-year growth of 35%. This growth was led by solid performance across all of our product lines, especially in our high-power laser cleaning processing applications and affordable entry-level systems. We attribute this growth to our continued investment in sales and marketing and capitalizing on our existing and newly installed customer base.We are also making investments in R&D to develop world-class products that meet the demands of our customers in industrial, automotive, MRO and nuclear facility decommissioning markets.
Moving to our growth investments, which, as we said on our recent fourth quarter earnings call, would negatively impact profits this year. From a personnel perspective, we brought on Peter and Bill, 2 C-level executives with proven success in relevant verticals at larger companies. We also expanded our marketing department to 13 people to support anticipated growth and added 4 outside sales professionals to target the DoD, automotive and energy industries and strategic geographic areas. Furthermore, we are building an AI and big data team, which will primarily focus on targeting specific end users, such as plant managers, department managers and chief engineers, from selected industries and verticals, including the automotive, aeronautical and maritime sectors, to enhance lead creation while decreasing customer acquisition costs.
For R&D, we maintain several programs and activities to improve our technology and processes to enhance performance to reduce the cost of our laser cleaning systems. In Q1, we increased R&D investments to stay ahead of our competition. We equip our application center with state-of-the-art laser blasters and develop new complementary technologies, such as remote particle removal for energy transmission power lines and infrastructure projects, maintenance, repair and construction. Moving forward, we intend to make further investments in R&D to innovate and guarantee the company's long-term future.
Now I'd like to turn the call over to our President, Mr. Peter Evans, for a detailed review of our sales and marketing efforts.
