Key Financial Metrics

Material Changes vs. Prior Period

• Goodwill Impairment: The Company recorded a non-cash goodwill impairment charge of $151.1 million in Q2 2025. This charge was driven by a sustained decline in the Company's market capitalization, which triggered an interim impairment test. The impairment was allocated to the Fluid Solutions ($77.6 million) and Services ($73.5 million) reporting units.
• Revenue Growth: Total revenues increased slightly by 0.5% in Q2 and 4.4% YTD compared to the prior year, driven by increased customer demand in the semiconductor industry. International revenues grew 3.9% in Q2, offsetting a 7.9% decline in U.S. revenues.
• Margin Compression: Gross margins declined to 15.3% in Q2 from 17.1% in the prior year due to higher employee costs, restructuring expenses, and inflation. Operating margins turned negative (-27.3%) primarily due to the goodwill impairment and increased stock-based compensation.
• Customer Concentration: Revenue concentration remains high, with Lam Research Corporation and Applied Materials, Inc. accounting for 56.0% of total revenues in Q2 2025.

Guidance, Outlook, and Risks

• Internal Control Weaknesses: Management concluded that disclosure controls and procedures were not effective as of June 27, 2025, due to material weaknesses in internal control over financial reporting. These include deficiencies in IT general controls for certain subsidiaries and segregation of duties. A remediation plan is underway, including ERP migration and hiring additional personnel.
• Litigation: A putative securities class action lawsuit was filed on March 24, 2025, alleging misleading statements regarding demand in the Chinese market. Management intends to vigorously defend the claims, which are currently in early stages.
• Liquidity: The Company maintains $327.4 million in cash and cash equivalents and has $146.4 million available under its revolving credit facility. Management believes existing resources are sufficient to meet obligations for the next 12 months.
• Tax Law Changes: The Company is evaluating the impact of the "One Big Beautiful Bill Act" (OBBBA) signed on July 4, 2025, which includes changes to R&D expensing and interest deduction limits. Preliminary analysis suggests no material change to the effective tax rate due to existing valuation allowances.

Investor Verification Checklist

• Goodwill Impairment Details: Verify the specific assumptions used in the fair value assessment (discount rates, growth projections) that led to the $151.1 million charge.
• Remediation Timeline: Monitor the progress of the remediation plan for material weaknesses in internal controls, specifically the ERP migration for Fluid Solutions subsidiaries.
• Legal Proceedings: Track the status of the securities class action lawsuit filed in March 2025 and any potential settlement costs.
• Customer Concentration Risk: Assess the impact of potential demand shifts from top customers (Lam Research and Applied Materials), which represent over half of total revenue.
• Debt Covenants: Confirm continued compliance with financial covenants (fixed charge coverage and leverage ratios) given the recent operating losses.
