Sono-Tek's medical sales jump 289% to $7.1M as it pivots to production platforms

Sono-Tek is shifting from selling coating components to selling integrated production platforms, as medical customers move from research into commercial manufacturing. Medical sales rose 289% to $7.1 million in its second quarter of fiscal 2027, and gross margin reached 55%. Management warned that the margin was unusually favourable, helped by US shipments that avoid distributor discounts. It also received a record $7.2 million order from an alternative energy customer, though demand in that sector has weakened after government policy changes. Recent record orders totalling more than $10.79 million give early visibility into fiscal 2028. Sono-Tek expects flat to modest revenue growth in fiscal 2027. A multi-phase facility expansion starting in December 2026 would lift capacity from about $27 million to $45 million. The company has no debt and holds $17.7 million in cash.

Sono-Tek falls short on Q2 2027: $0.02 EPS vs $0.04 expected.

Sono-Tek falls short on Q2 2027: $0.02 EPS vs $0.04 expected. Earnings Miss. Sono-Tek Corporation (NASDAQ:SOTK) posted Q2 2027 diluted EPS of $0.02, falling short of the $0.04 estimate by 50.0%. Revenue totaled $5.7M f... AlphaStreet Newsdesk powered by AlphaStreet Intelligence SOTK | EPS $0.02 vs $0.04 est (-50.0%) | Rev $5.2M | Net Income $366,000 Stock $6.09 (-14.4%) Earnings Miss. Sono-Tek Corporation (NASDAQ: SOTK) posted Q2 2027 diluted EPS of $0.02, falling short of the $0.04 estimate by 50.0%. Revenue totaled $5.23M for the quarter, up 1.0% from $5.16M in Q2 2026. Net income reached $366,000 for the quarter. The scientific and technical instruments manufacturer saw shares fall 14.4% in midday trade on Wednesday. Medical Strength Offsets. The quality of this quarter centered on dramatic growth in Sono-Tek's medical market segment, which led with $3.1M in revenue, up 209.0% year-over-year. Medical market sales growth reflected the company's successful pivot toward higher-margin healthcare applications of its ultrasonic coating technology. This triple-digit expansion in the medical vertical provides a compelling growth narrative even as the top-line advance remained modest at 1.0%, indicating weakness in other end markets that offset the medical surge. Profitability Pressures. Year-over-year, EPS moved down 33.3% from the $0.03 posted in Q2 2026, a concerning decline given that revenue actually grew during the period. The deterioration in per-share earnings despite revenue expansion points to margin compression, potentially driven by product mix shifts, operational investments to support the medical market ramp, or cost inflation that the company has yet to fully pass through to customers. For a precision instruments manufacturer, maintaining pricing power while scaling new market segments remains critical to margin preservation. Backlog Visibility. The company had $9.51M in combined equipment and service-related backlog at quarter end, providing some forward revenue visibility for this capital equipment business. This backlog metric offers reassurance that the medical market strength isn't simply a one-quarter anomaly, though the conversion timeline from backlog to recognized revenue will be important to monitor in coming quarters. Analyst Positioning. Wall Street consensus stands at 4 buy, 2 hold, 0 sell, indicating analysts maintain conviction despite the earnings miss. The bullish tilt suggests the Street views the medical market transformation as a sustainable growth driver that should eventually translate to improved profitability as the business scales and operating leverage returns. What to Watch: The critical question for SOTK centers on margin recovery timing. With medical revenue tripling year-over-year yet EPS declining, investors need clarity on when operating leverage materializes and whether the 209.0% medical growth rate proves sustainable enough to drive consolidated margin expansion in the back half of 2027.

Kingston retains no. 1 position in global DRAM module market.

Kingston retains no. 1 position in global DRAM module market. Sono-Tek to introduce SPT300WS automated ultrasonic wafer Coating System at SEMICON Europa. October 13, 2026 Sono-Tek SPT300WS Ultrasonic Coating System - Sono-Tek Corporation will introduce its new SPT300WS automated ultrasonic photoresist coating system at SEMICON Europa, November 10-13, 2026, at Messe München in Munich, Germany. The system will be exhibited in Sono-Tek Booth C1.254. Developed for precision semiconductor manufacturing, the SPT300WS expands Sono-Tek's automated wafer-coating platform to provide standard processing capability for wafers up to 300 mm. The fully enclosed system is designed for photoresist and protective coating applications, including MEMS, advanced packaging and wafers with deep wells, high-aspect-ratio features or other challenging three-dimensional topographies. The SPT300WS incorporates automated wafer-shuttle capabilities similar to Sono-Tek's established SPT200WS platform. The automation is designed to transfer wafers between the cassette, pre-alignment station and coating module, reducing operator involvement and supporting repeatable production processing. "The SPT300WS represents an important expansion of our semiconductor coating platform," said Steve Harshbarger, CEO and President of Sono-Tek Corporation. "It combines the precision and material efficiency of ultrasonic spray coating with 300 mm wafer capability and production-oriented automation. This gives semiconductor manufacturers a scalable alternative for coating complex wafer topographies that can be difficult to address with conventional spin-coating methods." Source Parts The SPT300WS incorporates a high-uniformity heated vacuum wafer chuck with automatic lift pins, programmable XYZ motion, a repeatable syringe pump with automatic refill and an integrated 360-degree bottom-draw exhaust system. An ISO Class 5 work area with HEPA-filtered air intake helps maintain process cleanliness, while photosensitive lighting, automatic nozzle cleaning and integrated photoresist monitoring support controlled and repeatable operation. Discover more Electronics news India Tech news India Automotive electronics components Depending on the application, the system can be configured with Sono-Tek's AccuMist or Vortex ultrasonic spray-shaping nozzles. The nozzles produce precise, controllable spray patterns at very low flow rates and can reduce photoresist consumption by up to 90% compared with conventional coating methods. Their non-clogging operation and low-velocity spray are particularly effective for producing uniform thin-film coverage over trenches, deep wells and other three-dimensional wafer features. Additional SPT300WS capabilities include: * Processing of 100, 125, 150, 200 and 300 mm wafers * Standard 300 mm heated vacuum wafer chuck * Automated wafer-shuttle integration * Deposition uniformity and repeatability of +/-2%, application dependent * Flow rates ranging from 1 μL/min to 30 mL/min * Programmable, Windows-based process control with a 22-inch touchscreen * UV-safe photosensitive lighting * Heat-plate temperatures up to 150°C * Automatic nozzle-cleaning purge * Integrated cleaning-liquid and overspray containment * CE-certified design

Sono-Tek hits $20.9M revenue with 81% operating income surge despite clean energy slump

Sono-Tek Corp reported its third consecutive year of revenue growth, reaching $20.9 million in fiscal 2026, with gross margins expanding to 51% and operating income growing 81%. The medical sector was particularly strong, posting 54% revenue growth driven by demand for advanced medical technologies. However, the clean energy market declined 19% due to reduced electrolysis demand, whilst the industrial market also showed weakness. The company reported a book-to-bill ratio of 0.44 for the quarter, indicating challenges in order intake. Sono-Tek maintained a debt-free balance sheet with $14.8 million in cash and marketable securities. The company anticipates continued revenue growth in the first half of fiscal 2027, driven by medical sector momentum, though visibility beyond that remains limited due to clean energy uncertainty.
