Sono-Tek Corporation, a developer and manufacturer of ultrasonic coating systems, has been shifting its mix toward larger, higher-value production machines with higher ASPs (average selling prices). That transition has helped expand profitability even as revenue growth has remained modest. This fiscal second quarter report matters because it shows whether the company can sustain margin momentum while clean energy demand softens, and whether strength in medical and electronics markets is enough to offset that weakness. With a growing backlog and a clean balance sheet, investors are watching how effectively management converts orders into revenue as it prepares for the next fiscal year.
For the fiscal second quarter ended August 31, 2026, Sono-Tek reported total revenue of approximately $5.23 million, compared with $5.16 million in the prior-year period, an increase of about $69,000. For the first half of fiscal 2027, revenue increased 6% to roughly $10.9 million, up from $10.3 million in the first half of fiscal 2026.
Gross profit for the second quarter was approximately $2.8 million, an increase of about 7% year over year, with a gross margin of roughly 53%, which management attributed to a favorable product and geographic mix. For the first half, gross profit rose 14% to about $6 million, lifting the gross margin to 55% from 51% a year earlier.
Operating income for the second quarter decreased 9%, or $39,000, to $382,000, driven by higher operating expenses. Net income was approximately $366,000, down from roughly $424,000 in the prior-year quarter, resulting in basic and diluted EPS of $0.02 compared with $0.03 a year ago. For the six-month period, net income increased to about $1.11 million from roughly $909,000, with EPS of $0.07 versus $0.06.

The market’s response to Sono-Tek’s results tends to hinge on two signals: the direction of gross margins and the trajectory of backlog, which provides visibility into future revenue. A modest top-line gain combined with softer second quarter profitability reflects the continued drag from reduced clean energy activity, particularly in electrolysis applications, even as medical and electronics demand remains firm. A 23% sequential rise in backlog and a stronger cash position are likely to be viewed as positive indicators, though investors remain attentive to whether higher operating expenses continue to pressure near-term earnings.
Looking ahead, management has indicated it expects continued revenue growth and profitability in the first half of fiscal 2027, supported by expanding medical-sector demand and broader adoption of high-ASP, production-scale coating systems. For the full year, Sono-Tek has projected revenue to be relatively flat to modestly higher compared with fiscal 2026, citing limited visibility beyond the first half and uncertainty in certain clean energy sectors.
Investors should monitor several factors. First, the conversion of backlog into recognized revenue, given that larger, higher-value system orders can create lumpiness in quarterly delivery timing. Second, the pace of order intake in medical and microelectronics, which management has identified as the primary sources of recent quoting activity.
Third, cost trends, since higher operating expenses were the main driver of the second quarter profit decline. Finally, developments in the clean energy market, including policy shifts affecting electrolysis demand, will continue to shape the company’s sales mix. The strengthened backlog and balance sheet provide a foundation, but the timing of large orders remains a key swing factor for quarterly results.
