Performance Analysis

PDF Solutions posted $47.8 million in Q1 revenue, up 16% year-over-year, marking its second-best quarter ever behind Q4’s E-Probe-driven peak. Analytics revenue, the company’s core software and services engine, grew 10% YoY to $42.5 million, reflecting continued enterprise adoption but a sequential dip due to Q4’s hardware spike. IYR (yield ramp and gainshare) revenue surged 86% YoY from a low base, now approaching 10% of total business as new fab and node contracts ramp.

Gross margin expanded to 77%, up five points YoY and QoQ, as recurring software and gainshare revenue outpaced lower-margin hardware. Operating margin held steady at 18%, with net income up 40% YoY to $8.1 million, despite increased SG&A from elevated pre-sales and pilot activity. SecureWise contributed less than one month of revenue but is already accretive to both gross and operating margins, reinforcing the platform’s high-quality revenue profile. Cash fell to $54 million post-acquisition, offset by $70 million in new bank debt, but positive operating cash flow of $9 million signals healthy underlying profitability.

• Recurring Revenue Mix Drives Margin: Shift toward SaaS and gainshare streams, plus SecureWise’s subscription-heavy model, boosted gross margin to 77%.
• Enterprise Wins Build Backlog: Sapiens Manufacturing Hub and Accentio bookings contributed to a $227 million backlog, up sequentially.
• Disciplined Opex Growth: SG&A rose 6% on higher sales activity, but operating leverage preserved margin expansion.

PDFS’s financial profile now reflects a true platform business, with recurring analytics and enterprise deployments supporting both top-line growth and high-margin conversion. The SecureWise acquisition is already proving strategically and financially accretive, while robust backlog and customer activity underpin the company’s 21-23% growth target for the year.

Executive Commentary

Strategic Positioning

1. SecureWise Acquisition: Platform Expansion and Recurring Revenue

SecureWise, a $130 million acquisition, immediately deepens PDFS’s value proposition for secure, collaborative semiconductor data analytics. Its nearly all-recurring revenue model and accretive margin profile plug directly into PDFS’s platform, enabling tighter integration between equipment, foundries, and OSATs (Outsourced Semiconductor Assembly and Test). Customers value SecureWise’s global security standards and the ability to securely deploy AI models and manage data across geographies, a growing requirement as advanced packaging complexity rises.

2. Enterprise Software Adoption: Sapiens and Accentio Momentum

Enterprise-wide deployments of Sapiens Manufacturing Hub (SMH) and Accentio analytics are gaining traction, with a major pilot converting to full deployment and additional contracts expected this year. These solutions connect disparate manufacturing, engineering, and analytics systems, enabling customers to leverage AI and streamline operations. The company’s focus on integrating SMH, Accentio, and MLOps (machine learning operations) into a single platform is increasing stickiness and wallet share with fabless, foundry, and equipment customers.

3. Advanced Node and AI-Driven Demand

Industry demand is shifting toward advanced nodes, 3D processing, and AI-driven workflows. PDFS’s bookings and pipeline reflect customers’ need to manage more complex test flows and packaging, areas where its analytics and DFI (Design-for-Inspection) tools excel. The company shipped two DFI systems to logic customers in Q1, with DRAM applications expected to follow, and sees strong demo and engineering activity supporting further shipments and revenue recognition in the second half.

4. Capital Allocation and Balance Sheet Discipline

PDFS used $61 million cash and added $70 million in five-year bank debt to fund SecureWise, but remains focused on debt reduction as a top priority. Management signaled willingness to consider opportunistic share buybacks as cash flow allows, but expects to maintain a conservative balance sheet to support ongoing platform investments.

5. Evolving Go-to-Market and Sales Execution

Sales and marketing investment increased to convert pilots and drive enterprise adoption, but management acknowledges further improvement is needed in scaling new technology deployments. The company is actively refining sales processes to accelerate the conversion of R&D innovation into revenue, recognizing that complex enterprise sales cycles require persistent engagement and customer enablement.

Key Considerations

This quarter marks a strategic inflection for PDF Solutions, as the business model pivots further toward high-value, recurring platform revenue and deepens its integration across the semiconductor supply chain.

Key Considerations:

• SecureWise Integration Synergies: Immediate customer interest in combining SecureWise security with PDFS analytics and DEX nodes signals cross-sell potential and platform stickiness.
• Margin Expansion Sustainability: Gross margin gains hinge on continued mix shift toward SaaS, analytics, and gainshare, with hardware sales variability now less impactful.
• Enterprise Sales Cycle Complexity: Converting pilots to full deployments remains a multi-quarter process, especially for large-scale solutions like Sapiens Manufacturing Hub.
• Capital Allocation Focus: Debt reduction is prioritized post-acquisition, but positive cash flow and a growing backlog provide optionality for opportunistic buybacks or further investment.

Risks

Macro uncertainty, including semiconductor demand cycles and regulatory shifts such as tariffs, could impact customer spending or hardware cost structure, though management sees minimal near-term effect. Integration execution risk remains for SecureWise, especially in scaling cross-sell and technical integration. Enterprise sales cycles for analytics and manufacturing platforms remain long and lumpy, potentially delaying revenue recognition if pilots stall. Sustaining margin expansion will require disciplined opex management as the company invests in sales and product enablement.

Forward Outlook

For Q2 2025, PDF Solutions expects:

• Continued sequential improvement in IYR revenue as new contracts ramp
• Additional Sapiens Manufacturing Hub and SecureWise bookings to support backlog growth

For full-year 2025, management reaffirmed guidance:

• Revenue growth of 21%-23% over 2024, ahead of its long-term 20% target

Management emphasized:
