StoneRidge (SRI) Q4 2025: Mirai Platform Grows 69% as Control Devices Exit Reshapes Portfolio
StoneRidge’s portfolio transformation accelerates as Mirai, its digital vision platform, surges and the company exits its legacy control devices business. Operational discipline and cost reductions offset severe end-market contraction, positioning SRI for margin expansion as commercial vehicle markets stabilize. Management’s focus on advanced safety and connectivity solutions signals a long-term pivot to higher-growth, higher-margin segments.
Summary
- Portfolio Realignment: Divestiture of control devices sharpens the focus on advanced electronics and connectivity.
- Mirai Momentum: Rapid adoption of MirrorEye and digital safety platforms drives outperformance versus end markets.
- Operational Discipline: Cost controls and inventory management underpin cash flow resilience amid volatile demand.
Performance Analysis
StoneRidge delivered a year marked by strategic transition, with the successful sale of its control devices segment and a sharpened focus on electronics and Brazil operations. Despite a nearly 7% decline in weighted average OEM end markets, SRI outperformed by 150 basis points, led by Mirai, the company’s digital vision system platform, which grew 69% to $111 million. Electronics now represent the core of StoneRidge’s business, accounting for the majority of revenue and setting the stage for technology-driven growth.
Cost discipline remained a defining theme: material costs were reduced by 80 basis points, and quality-related costs fell by $6.6 million, even as legacy warranty settlements created fourth quarter headwinds. Free cash flow reached $19 million, supported by an $18.7 million inventory reduction. Tariff-related expenses and adverse foreign exchange impacted results, but management expects to recover most tariff costs in coming periods. The Mirai platform’s strong market acceptance, especially with new OEM launches in Europe and North America, offset volume declines in other categories.
- Segmental Shift: Electronics and Brazil now comprise 100% of ongoing operations after the divestiture, with Brazil contributing around 15% of revenue.
- Mirai as Growth Engine: Mirai’s OEM revenue rose 84%, fueled by increasing take rates and new programs with Daimler and Volvo.
- Cash Focus: Inventory and capital management drove positive free cash flow despite margin compression.
While adjusted EBITDA margin dipped 60 basis points, the decremental margin of 14.2% was well below historical averages, highlighting effective cost containment in the face of severe end-market contraction. Management’s pivot to high-return platforms and disciplined execution positions SRI for improved margin leverage as industry volumes recover.
Executive Commentary
"Our outperformance was primarily driven by continued momentum with Mirai, resulting in sales of over $110 million, or approximately 70% growth compared to the prior year. In addition to strong performance this year, our strategy to grow the Mirai platform continues to pay off with additional business awards and expansion across many of our global OEMs."
Jim Ziselman, President and Chief Executive Officer
"For electronics, full-year sales of $551 million outperformed our weighted average OEM end markets by approximately 430 basis points. This market outperformance was driven by Mirai sales which totaled $111 million in 2025, resulting in growth of $45 million, or 69% compared to the prior year."

Strategic Positioning
1. Portfolio Simplification and Focus on High-Return Segments
The divestiture of the control devices segment marks a pivotal simplification, allowing StoneRidge to concentrate capital and management attention on advanced electronics, connectivity, and vision systems. This move reduces organizational complexity and is expected to enhance structural cost efficiency, with proceeds earmarked for debt reduction and interest savings.
2. Mirai Platform as the Core Growth Driver
Mirai, StoneRidge’s digital camera and vision system, replaces traditional mirrors with digital displays, offering safety, efficiency, and driver comfort. OEM adoption is accelerating, especially in Europe and North America, with strong customer feedback and marketing support. The platform’s expansion into connected trailer and 360-degree surround view solutions opens adjacent growth opportunities.
3. Global Engineering and Market Diversification
StoneRidge leverages a global engineering footprint, with Brazil as a critical R&D hub and India supporting cost-advantaged engineering. This enables rapid technology deployment and customization for leading OEMs across continents, mitigating region-specific risks and supporting local content requirements for commercial vehicle customers.
4. Cost and Quality Discipline
Ongoing material and quality cost reduction initiatives are embedded in the operating model. The company prioritizes early-stage quality processes to minimize long-tail warranty exposures and has a robust pipeline of supply chain and manufacturing efficiency projects to drive further margin expansion as volumes recover.
5. Digital Services and Recurring Revenue Potential
In Brazil, StoneRidge’s track and trace business is building a recurring revenue base from digital services, complementing hardware sales. While currently a smaller contributor, this segment positions SRI to participate in the secular shift toward telematics, compliance, and fleet management solutions globally.
Key Considerations
StoneRidge’s 2025 results reflect a business in strategic transition, balancing near-term market headwinds with long-term repositioning. The company’s focus on advanced technology, operational rigor, and global customer integration is reshaping its growth profile.
Key Considerations:
- Mirai Platform Scaling: Continued take rate increases and new OEM launches are expected to drive 45% Mirai growth in 2026, with further upside as market adoption accelerates.
- Cost Structure Reset: Structural cost reductions of at least $5 million are planned for 2026, with additional savings in 2027 as transition service agreements wind down.
- Quality Focus: Settling legacy warranty issues enables forward focus, while early-stage quality investments aim to reduce future exposures and costs.
- Cash Generation Discipline: Inventory management and capital expenditure oversight remain priorities, supporting liquidity and covenant compliance as end markets recover.
Risks
Geopolitical volatility, especially in Europe and North America, could disrupt OEM production forecasts and delay anticipated market recoveries. Tariff-related cost unpredictability and lingering quality settlements present near-term margin risk. Aftermarket and regulatory-driven products face cyclical and policy risk, as seen in the expected Smart2 tachograph sales decline. Management’s conservative revenue outlook reflects these uncertainties, but further market contraction or execution missteps could pressure results.
Forward Outlook
For Q1 2026, StoneRidge guided to:
- Approximately break-even EBITDA, reflecting muted production volumes and a seasonal revenue dip versus Q4 2025.
For full-year 2026, management maintained guidance:
- Revenue growth of approximately 4.2%, driven primarily by Mirai expansion, with weighted average OEM end markets assumed flat.
- Midpoint EBITDA guidance of $22.5 million, reflecting revenue growth, cost reductions, and incremental margin improvement in the second half.
Management highlighted several factors that shape the outlook:
- Mirai sales expected to reach $160 million, up 45% year over year, with OEM programs as the primary driver.
- Structural cost reduction and operating efficiency initiatives to support margin expansion as volumes recover.
Takeaways
StoneRidge’s transformation is now operationally visible, with Mirai’s growth offsetting legacy headwinds and the exit from control devices clarifying the business model. Investors should monitor the cadence of OEM recovery, Mirai adoption rates, and execution on cost initiatives for margin leverage.
- Growth Engine in Place: Mirai’s rapid scaling and strong OEM pipeline position SRI for outsized growth versus end markets as commercial vehicle production rebounds.
- Structural Simplification: The divestiture of control devices reduces complexity, sharpens capital allocation, and supports higher-margin, technology-driven segments.
- Execution Watchpoint: Margin recovery and cash generation depend on continued discipline in cost management and successful transition to a leaner, more focused organization.
Conclusion
StoneRidge’s Q4 2025 performance underscores a decisive strategic pivot, with Mirai’s growth and portfolio simplification setting a new trajectory. Operational rigor and global customer integration will be critical as the company navigates near-term market volatility and executes on its long-term value creation plan.
