8-K/A: Moog Inc. Changes Auditors, Cites Internal Control Weakness

Moog Inc. has dismissed Ernst & Young LLP as its independent auditor, effective November 26, 2025, and engaged KPMG LLP, following an adverse opinion on internal controls due to a material weakness.

Summary

• Moog Inc. dismissed Ernst & Young LLP (EY) as its independent registered public accounting firm, effective November 26, 2025.
• The dismissal occurred after EY completed the audit of the Company's consolidated financial statements and internal control over financial reporting for the fiscal year ended September 27, 2025.
• KPMG LLP (KPMG) has been engaged to serve as the Company's independent registered public accounting firm for the fiscal year ending October 3, 2026, with their review commencing for the quarter ending January 3, 2026.
• EY's audit reports on the consolidated financial statements for the fiscal years ended September 28, 2024, and September 27, 2025, did not contain an adverse opinion, disclaimer, or qualification.
• However, EY's report on the Company's internal control over financial reporting as of September 27, 2025, contained an adverse opinion.
• This adverse opinion was due to a material weakness identified by management in the design and operation of controls over distinct long-term aftermarket service revenue contracts in the Commercial Aircraft segment.
• The material weakness was previously reported by the Company in its Annual Report on Form 10-K for the fiscal year ended September 27, 2025.
• There were no disagreements between the Company and EY on accounting principles, financial statement disclosure, or auditing scope, other than the material weakness in internal controls.
• The Company did not consult with KPMG regarding any accounting or auditing matters prior to their engagement.

Sentiment

Score: 3

Explanation: The adverse opinion on internal controls and the identified material weakness are significant negative indicators for financial reporting reliability and corporate governance. While the consolidated financial statements were not qualified, the fundamental control issue raises serious concerns about the company's ability to accurately report its financial position and results.

Positives

• EY's audit reports on the consolidated financial statements for the fiscal years ended September 28, 2024, and September 27, 2025, did not contain an adverse opinion or qualification, indicating the financial statements themselves were presented fairly.

Negatives

• An adverse opinion was issued on the Company's internal control over financial reporting as of September 27, 2025.
• A material weakness was identified in the design and operation of controls over distinct long-term aftermarket service revenue contracts in the Commercial Aircraft segment.

Risks

• The identified material weakness in internal control over financial reporting, specifically concerning long-term aftermarket service revenue contracts in the Commercial Aircraft segment, poses a risk to the accuracy and reliability of future financial reporting.
• Ineffective internal controls could lead to undetected errors or fraud, potentially resulting in material misstatements in financial statements.
• The remediation of the material weakness will require significant management attention and resources, potentially diverting focus from other operational priorities.

Future Outlook

The Company has engaged KPMG LLP to serve as its independent registered public accounting firm for the fiscal year ending October 3, 2026, with their review of consolidated financial statements commencing for the quarter ending January 3, 2026. No other specific forward-looking statements or guidance were provided.

Management Comments

• The Company had not maintained effective internal control over financial reporting as of September 27, 2025, due to the effect of a material weakness identified by management in the design and operation of its controls over distinct long-term aftermarket service revenue contracts in the Company's Commercial Aircraft segment.

Industry Context

A change in independent auditors, especially following an adverse opinion on internal controls, is a significant event in the financial reporting landscape. While auditor rotations are common, the underlying reason of a material weakness in internal controls signals potential operational and financial reporting challenges. Companies in the aerospace and defense sector, like Moog, often manage complex, long-term contracts, making robust internal controls over revenue recognition particularly critical. This event could lead to increased scrutiny from investors and regulators regarding the company's financial governance and operational efficiency compared to industry peers.

Comparison to Industry Standards

• An adverse opinion on internal control over financial reporting is a serious finding, indicating that the company's internal controls are not effective and could lead to material misstatements in its financial statements. This falls significantly below industry best practices for financial reporting and corporate governance.
• Leading companies in the aerospace and defense sector, such as Boeing or Lockheed Martin, are expected to maintain strong internal control environments, particularly for complex revenue streams like long-term aftermarket service contracts. Moog's identified material weakness suggests a notable gap in its control framework compared to these industry benchmarks.

Corporate Governance

Stakeholder Impact

• Shareholders: May face increased uncertainty regarding the reliability of financial reporting and potential for future restatements or delays if the material weakness is not effectively remediated, potentially impacting investor confidence and stock valuation.
• Management: Will need to dedicate significant time, resources, and attention to remediating the identified material weakness and strengthening the internal control environment.
• Regulators (SEC): The adverse opinion on internal controls and the material weakness will likely draw increased scrutiny from the SEC, potentially leading to further inquiries or compliance requirements.
• Customers/Suppliers: While not directly impacted by the auditor change, the underlying control weakness could signal broader operational issues that might indirectly affect business relationships if not addressed.

Next Steps

• KPMG will begin reviewing the Company's consolidated financial statements for the quarter ending January 3, 2026.
• The Company's Audit Committee has authorized EY to respond fully to KPMG's inquiries concerning the material weakness.
• The Company will need to implement remediation efforts to address the identified material weakness in its internal controls over financial reporting.

Key Dates

Recommendation

The adverse opinion on internal controls over financial reporting, stemming from a material weakness in a critical revenue area (long-term aftermarket service contracts in the Commercial Aircraft segment), is a serious red flag. While the consolidated financial statements were not qualified, the inability to maintain effective internal controls raises significant concerns about the reliability of future financial reporting and the company's operational integrity. This fundamental governance issue warrants a cautious stance, suggesting a 'sell' recommendation until clear and effective remediation plans are demonstrated and implemented, and the new auditor provides clean opinions on internal controls.
