PDF Solutions has amended its credit agreement to increase its revolving credit facility to $75 million whilst maintaining other material terms unchanged. The amendment, executed on 23 April 2026, introduced leverage-based tiers for annual commitment fees. Under the new structure, the commitment fee is 0.50% when total debt to EBITDA reaches or exceeds 2.50 to 1.00, decreases to 0.35% for ratios between 0.50 and 2.50 to 1.00, and drops to 0.20% when the ratio falls below 0.50 to 1.00. This tiered approach aligns financing costs with the company's debt-to-EBITDA ratio, potentially lowering borrowing costs as leverage decreases. The adjustment provides added financial flexibility for the semiconductor analytics provider's operations and investment plans.
