Business Overview
Precision Optics Corporation develops and manufactures advanced optical instruments, specializing in proprietary medical endoscopes and custom optical components. The company operates through three main divisions: medical instrumentation including single-use and 3D endoscopes, aerospace optical components, and custom optical assemblies under the Ross Optical and Lighthouse Imaging brands. Revenue is generated primarily through production sales of medical and aerospace products and engineering design services.
Performance Analysis
In Q3 fiscal 2025, Precision Optics reported revenue of $4.2 million, down from $5.2 million a year earlier, primarily due to production disruptions in the single-use cystoscope program. Production revenue increased modestly to $3.2 million from $3.0 million, while engineering revenue declined sharply to $924,000 from $2.3 million, reflecting engineering resources diverted to resolving manufacturing yield issues. Gross margin contracted to 10% from 35% year-over-year due to lower yields, line shutdown, and under absorption of engineering costs.
The aerospace program continued its steady ramp, reaching nearly $900,000 in production revenue for the quarter, doubling output quarter-over-quarter and supported by a new manufacturing agreement with minimum annual purchase commitments of $4 million for 2025 and 2026. The company also initiated production on two additional medical programs, contributing $100,000 to $200,000 quarterly each.
- Yield Disruption Impact: A sudden drop in single-use cystoscope production yields to below 50% led to a temporary manufacturing halt and delayed revenue recognition.
- Engineering Resource Allocation: Significant non-billable engineering hours were spent on troubleshooting and ramp-up support, reducing billable engineering revenue.
- Backlog and Pipeline Growth: The company reported its largest backlog in over two decades, driven by strong demand from aerospace and single-use endoscope customers.
Despite short-term execution challenges, management expects a meaningful revenue rebound in Q4 with improved production throughput, margin recovery, and positive adjusted EBITDA driven by increased volumes and the Unity platform’s contribution to new program development.
Executive Commentary
"We have made significant progress on resolving the third quarter issues, and we have the largest production backlog in over 20 years. With a positive response to the launch of our Unity platform in Q3, we believe the underlying fundamentals of our strategy for business growth remain strong, and we look forward to recovering that growth in Q4 and beyond."
Dr. Joe Forkey, Chief Executive Officer
"Low yields forced us to pause production of our single-use cystoscope, resulting in unplanned increases in non-billable, sustaining engineering activities. With the launch of Unity and strong trade show interest, we've seen the pace of engineering pipeline opportunities increasing. We expect to finish our fiscal year strongly with $6 million in sales next quarter."
