Management views validated systems as a leading indicator of future recurring revenue, as customers transition to routine use of consumables post-validation.

The company's financial trajectory is also showing significant improvement. After years of incurring net losses, RPID achieved positive gross margins for the first time in Q3 2024 and has maintained this trend. In Q3 2025, gross margins reached 9%, a 70 basis point improvement from the prior year quarter. This was largely propelled by service margins of 40%, driven by higher revenue, productivity gains, and lower service headcount. While product margins remained slightly negative in Q3 2025, the company anticipates achieving positive product margins in Q4 2025 due to ongoing product cost reduction and manufacturing efficiency initiatives. For the full year 2024, gross margins were effectively breakeven, a substantial improvement from negative 24% in 2023.

The operational efficiency program initiated in August 2024, which included workforce reductions and other cost-saving measures, has played a significant role in this margin expansion, with its full benefits realized by the end of Q1 2025. Total operating expenses decreased by 5% in Q3 2025 compared to the prior year, reflecting these efforts.

Strategic Partnerships and Future Outlook

RPID's strategic initiatives are designed to accelerate its growth trajectory and solidify its market leadership. A cornerstone of this strategy is the Distribution and Collaboration Agreement with MilliporeSigma , announced in February 2025.
