• The Company did not consult with KPMG on specific accounting issues or audit opinions prior to their engagement.

Sentiment

Score: 4

Explanation: The change in auditor itself is neutral, but the persistent material weakness in internal controls, leading to adverse opinions for two consecutive years, is a significant negative factor. This raises concerns about the reliability of financial reporting, despite the unqualified opinion on the financial statements themselves. The competitive process for auditor selection is a positive, but it doesn't outweigh the internal control issue.

Positives

• The change in auditor followed a competitive process conducted by the Audit Committee, suggesting due diligence.
• Grant Thornton's audit reports on the consolidated financial statements for fiscal years 2024 and 2025 were unqualified.
• No disagreements on accounting principles or practices were reported between the Company and Grant Thornton.

Negatives

• Grant Thornton issued adverse opinions on the Company's internal control over financial reporting for both fiscal years ended October 31, 2025, and October 31, 2024.
• A material weakness in the design and operation of controls over the preparation and review of the Company's statement of cash flows was identified and continues to exist.

Risks

• A material weakness in internal control over financial reporting, specifically concerning the preparation and review of the statement of cash flows, which could lead to errors in financial reporting.
• The adverse opinion on internal controls indicates a heightened risk of financial misstatement.

Future Outlook

The Company will continue to address the identified material weakness in its internal control over financial reporting, as it has persisted since its initial disclosure in late 2024.

Management Comments

• The Audit Committee approved the decision to change the Company's independent registered public accounting firm.
• Management previously reported the material weakness in Part II, Item 9A of its Annual Reports on Form 10-K for the fiscal years ended October 31, 2025, and October 31, 2024.

Industry Context

Changes in independent auditors are common, often driven by competitive bidding processes or a desire for fresh perspectives. However, such changes, especially when accompanied by persistent material weaknesses in internal controls, warrant close scrutiny by investors as they can signal underlying issues in financial reporting integrity. Strong internal controls are a fundamental expectation for publicly traded companies, and a material weakness can impact investor confidence and the reliability of financial statements.

Comparison to Industry Standards

• Maintaining effective internal control over financial reporting is a fundamental requirement for publicly traded companies under Sarbanes-Oxley Act (SOX) Section 404. The persistent material weakness at Quanex Building Products Corporation, specifically concerning the statement of cash flows, falls short of industry best practices and regulatory expectations.
• Companies like Microsoft or Apple, for instance, consistently report effective internal controls, which is the industry standard for large, complex organizations. The adverse opinion from Grant Thornton highlights a significant deviation from this standard, indicating a higher risk profile compared to peers with robust control environments.
• While auditor changes are routine, the context of a material weakness makes this change more notable. Peer companies typically change auditors without such a significant disclosure regarding internal control deficiencies.

Corporate Governance

Stakeholder Impact

• Shareholders: Potential impact on investor confidence due to the persistent material weakness in internal controls, which raises questions about the accuracy and reliability of financial reporting.
• Management: Increased pressure to remediate the identified material weakness and ensure effective internal controls.
• Audit Committee: Continued responsibility to oversee the remediation of the material weakness and ensure the effectiveness of the new auditor.

Next Steps

• KPMG LLP will serve as the independent public accounting firm for the fiscal year ending October 31, 2026.
• The Company's management is expected to continue its efforts to remediate the identified material weakness in internal control over financial reporting.

Key Dates

Recommendation

While the change in auditor to KPMG is a standard corporate action, the persistent material weakness in internal control over financial reporting, specifically concerning the statement of cash flows, is a significant concern. This issue has led to adverse opinions on internal controls for two consecutive fiscal years and continues to exist. This raises questions about the reliability of the Company's financial reporting, despite unqualified opinions on the financial statements themselves. Investors should hold and monitor the Company's progress in remediating this material weakness, as its resolution is crucial for long-term investor confidence and financial integrity. Until this fundamental issue is resolved, a 'buy' recommendation would be premature, and a 'sell' would be an overreaction to an issue that management is aware of and presumably working to fix.
