The pump manufacturer reported adjusted earnings per share of $0.55 for Q4 2025, beating analyst estimates of $0.47 and representing a significant increase from $0.42 in the same period last year. Net income rose 24.5% year-over-year to $13.7 million, while revenue increased 2.4% to $166.6 million, driven primarily by strong demand in fire suppression, industrial, and OEM markets due to data center construction.
