This surge was driven by large deals across leading-edge customers, SecureWise, and the Accentio product suite, pushing total backlog to $292 million, a 25% sequential and 22% year-over-year increase.
Gross margin held at 76%, slightly ahead of the long-term target, even as perpetual software revenue declined as a mix. Operating expenses rose 3% sequentially, reflecting higher R&D and variable compensation tied to outperformance. CapEx moderated as major investments in SecureWise integration and E-Pro machine builds tapered off, with management signaling a return to cash generation in 2026. Customer concentration increased, with a single customer accounting for 38% of revenue, reflecting multi-contract wins rather than reliance on one deal.
- Bookings Outperformance: Bookings growth of 49% year-to-date validates demand for PDFS’s manufacturing analytics and connectivity solutions.
- Analytics as Growth Engine: Accentio and SecureWise are now core drivers, with multi-year, multi-product contracts expanding customer footprint.
- Cash Flow Inflection: Operating cash flow turned positive despite elevated investment, with CapEx expected to decline further.
The combination of record revenue, expanding backlog, and broadening product adoption signals a durable shift in PDFS’s operating model from investment-led to platform monetization.
Executive Commentary
"With our Q3 results, we achieved another record for quarterly revenue. Our bookings for this quarter totaled over $100 million as a result of multiple large deals signed across our product portfolio of Leading Edge, Xencio, and SecureWise. During the third quarter, our bookings were greater than the prior two quarters combined."
Adnan Raza, Chief Financial Officer
"We see PDF becoming a platform for the industry rather than a platform for each individual company. And SecureWise is a very important element to that."
John Kibarian, President and Chief Executive Officer
Strategic Positioning
1. SecureWise as Industry Standard
SecureWise, PDFS’s secure remote connectivity platform, is gaining adoption as a standard across both equipment vendors and fabs. The Intel win will see SecureWise deployed on every Intel machine, broadening access for equipment vendors and enabling new forms of collaboration and AI-driven diagnostics. This creates a network effect, as smaller vendors seek the same access historically reserved for industry giants.
2. Accentio and AI-First Analytics
Accentio, the company’s analytics platform, is evolving to deliver AI-first, highly parallelized analytics at scale. Management highlighted customer demand for interactive, large-scale data analysis—capabilities conventional business intelligence tools cannot match. The upcoming integration of Studio AI will allow Accentio to operate on massive datasets, supporting advanced manufacturing and test flows. Multi-year contracts, including an eight-figure Accentio deal, signal robust renewal and upsell potential.
3. E-Pro and Yield Ramp Expansion
The E-Pro machine business, focused on advanced inspection and yield optimization, is scaling through a subscription model. Two new machines shipped this quarter, with additional units in qualification and a pipeline of 5 to 10 active customer engagements worldwide. The minimum deployment is two machines per site, reflecting mission-critical status for production continuity.
4. Multi-Segment Customer Penetration
PDFS’s business is diversifying across fabs, fabless/system companies, and equipment vendors. Fabs account for 40-50% of revenue, fabless and system companies for 35-45%, and equipment vendors for 15-20%. SecureWise is the “point of the spear” for cross-segment collaboration, while Accentio and orchestration products drive adoption deeper into the value chain.
5. Investments Transitioning to Monetization
2025 was a peak investment year, with cash deployment for SecureWise integration and E-Pro builds. With integration costs largely behind and subscription revenue ramping, management expects a return to cash generation and operating leverage in 2026.
Key Considerations
PDF Solutions is at an inflection point, shifting from heavy investment to platform monetization as its backlog and customer footprint expand. The SecureWise and Accentio platforms are now central to both customer acquisition and long-term recurring revenue growth, but customer concentration and the timing of large contract qualifications remain key watchpoints.
Key Considerations:
- Platform Network Effect: SecureWise’s adoption by both equipment vendors and fabs is creating a connectivity standard that could entrench PDFS across the industry.
- AI-Driven Analytics Differentiation: Accentio’s move to AI-first, native parallelization positions PDFS to win analytics workloads that legacy BI providers cannot address.
- Customer Concentration Risk: A single customer now represents 38% of revenue, reflecting multi-contract wins but also increasing exposure to contract timing and renewal dynamics.
- CapEx and Cash Flow Leverage: With major investments behind, PDFS is positioned for improved cash generation as subscription and recurring revenues scale.
- Operational Visibility: Backlog and pipeline strength provide high revenue visibility, but qualification timing for E-Pro and large contracts could swing quarterly results.
Risks
Customer concentration and large deal timing create quarterly revenue lumpiness and potential renewal risk. The transition to a platform model hinges on continued adoption of SecureWise and Accentio, with competitive threats from larger analytics or equipment software providers. Integration of acquired assets and successful qualification of new E-Pro deployments remain operational execution risks, while macro uncertainty in semiconductor capital spending could impact near-term demand.
Forward Outlook
For Q4, PDF Solutions guided to:
- Sequential revenue growth, underpinned by backlog conversion and additional large contracts.
- Continued margin discipline, with gross margin expected near the 75% long-term target.
For full-year 2025, management reaffirmed guidance:
- 21% to 23% annual revenue growth
Management highlighted several factors that will drive results:
- Further SecureWise and Accentio contract wins, with multi-segment expansion
- Potential upside from E-Pro machine qualifications and additional shipments
Takeaways
PDF Solutions is now operating with a platform mindset, leveraging SecureWise and Accentio to embed itself deeper across the semiconductor manufacturing ecosystem. The company’s record backlog, robust bookings, and multi-segment traction provide high visibility, but customer concentration and execution on new deployments remain key variables.
