Detailed narrative
Medical Market Growth and Production Transition
The medical market was a primary growth driver in the first half of FY27, with sales increasing 289% to $7.1 million. This growth is fueled by customers transitioning from process development to commercial manufacturing, particularly in drug-eluting balloon coating systems and specialty stent applications.
This shift is critical as production applications involve larger, more sophisticated systems with higher average selling prices (ASPs) and opportunities for follow-on equipment and services. Sono-Tek is recognized as an industry leader in drug-eluting balloon coating, with customers increasingly bringing next-gen medical devices for lab validation.
Strategic Shift to High-Value Production Systems
Sono-Tek is increasingly providing complete production solutions rather than just coating systems, leading to significantly higher ASPs. This strategy is supported by the Forward Deployed Engineering (FDE) team, which integrates Sono-Tek's ultrasonic technology into larger production platforms. The company's success in the clean energy sector, where it developed high-value production expertise, has been successfully replicated in the medical sector, leading to more extensive and capable systems with ASPs of $250,000-$300,000 for drug-eluting balloons, compared to $75,000-$100,000 for earlier stent coating systems.
Record Backlog and FY28 Visibility
The company announced record orders, including $7.2 million for alternative energy and over $3.6 million for medical diagnostics, totaling more than $10.79 million in backlog. As of August 31, 2026, the backlog stood at $9.5 million, a 23% increase from the prior quarter.
The majority of these significant orders are expected to be delivered in fiscal year 2028, providing substantial early visibility into the next fiscal year and demonstrating the long-term potential of Sono-Tek's technology and customer relationships.
Organic Investment in Forward Deployed Engineering (FDE)
Sono-Tek is doubling down on organic investments, particularly in its FDE team, which has grown from one person 2.5 years ago to four (three engineers, one project manager). This team works closely with customers to integrate ultrasonic technology into production platforms, generating meaningful returns within one to two years compared to five to six years for traditional R&D.
The FDE team's success in securing large, integrated orders is a key driver of the company's growth strategy, with plans to further expand the team.
Manufacturing Capacity Expansion Plans
To support increasing demand and larger orders, Sono-Tek plans a major manufacturing expansion starting in December/January. This involves building a mezzanine structure and optimizing manufacturing flow, which will increase capacity from $27 million to $33-$36 million. A subsequent retrofit of an unoccupied building will further boost capacity to $44-$45 million.
The company is also beginning planning for a future expansion to $85 million, considering incentives from New York State and alternative locations like South Carolina.
Semiconductor and Microelectronics Opportunity
Sono-Tek sees a broad and growing opportunity in the microelectronics sector, including semiconductors. While initially focused on photoresist, the company is receiving inquiries for other thin film processes, particularly for next-gen chips in the AI world. Sono-Tek is working to scale its offerings from lab and low-volume production to fab-level for 200mm and 300mm wafers, with a focus on SEMICON Europe.
The company believes this could become its largest sector in the future, despite a longer sales cycle for significant impact.
Defense Sector Potential
The industrial business saw a 156% increase in the first half, influenced by an optics-related shipment to the defense sector. Management views defense as a high-tech, less price-sensitive market with good margin potential, aligning with Sono-Tek's strategy. While not currently a primary focus for trade shows or marketing, the company is exploring applications in optics for flying objects and sensors, and may soon establish a dedicated presence for this sector on its website and in marketing efforts.
