Total revenue decreased by $4.3 million, or 11%, to $36.2 million for the three months ended September 30, 2025, from $40.5 million for the three months ended September 30, 2024. The decrease was primarily driven by a decrease in Units Shipped to 20,047 for the three months ended September 30, 2025 from 44,763 for the three months ended September 30, 2024, partially offset by an increase in New Units Deployed to 22,644 units for the three months ended September 30, 2025 from 15,168 units for the three months ended September 30, 2024. The overall decrease in Units Shipped is primarily attributable to our customers' decisions to defer capital expenditures, driven by broader macroeconomic conditions. In addition, changes in leadership and the structure of our sales organization have adversely impacted sales and overall volumes.
