Revenue Growth and Earnings Performance:
- PDF Solutions reported total revenues of $47.8 million for Q1 2025, up 16% year-on-year.
- The growth was driven by strong bookings in enterprise solutions, particularly the Sapience Manufacturing Hub Enterprise, and increased revenue from a new gain share customer engagement.

IYR Revenue Improvement:
- PDF's IYR revenue was up 86% for Q1, contributing $2.5 million to the total revenue growth.
- This improvement was due to the start of a new gain share engagement with a customer, which is expected to continue to enhance IYR revenues throughout the year.

eProbe Tool Shipments and Revenue Projections:
- PDF shipped 2 eProbe tools in Q1, with expectations for one of these to contribute incremental revenue growth this year.
- The company remains committed to shipping at least 4 eProbe tools for the year, with these shipments contributing to demo, install, and engineering activity with customers.

Integration of New Acquisition SecureWise:
- SecureWise, acquired in Q1, contributed less than a month of revenues, with expectations for increased integration with the PDF platform.
- The acquisition aligns with PDF's strategy to enhance collaboration and security across the supply chain, particularly with advanced packaging and AI/ML systems.

Gross Margin and Operating Profitability:
- PDF's gross margin for the quarter was 77%, up from 72% in the previous quarter, driven by increased gain share and lower cost of sales due to eProbe machine expenses.
- The operating margin was 18%, with $8.6 million of operating profit, reflecting a focus on efficiency and cost control.
