Critical Audit Matters

Impact of Rate Regulation on Financial Statements

The report highlights the complexity and risk associated with Otter Tail’s regulated Electric segment, which accounts for the effects of rate regulation under ASC 980. This allows the company to record regulatory assets or liabilities for certain costs or credits that are expected to be recovered or returned in future rates. The report notes that there is a risk that regulatory commissions may not approve full recovery of costs or provide a reasonable return on investment, which could materially impact future results and share value.

The audit involved a thorough review of the company’s controls and management’s judgments regarding the recoverability of regulatory assets and the likelihood of future rate reductions. Given the subjectivity and complexity in regulatory matters, this is an area of heightened attention for both management and investors.

Internal Controls and Audit Opinion

• The independent auditor, Deloitte & Touche LLP, provided an unqualified (“clean”) opinion on both the financial statements and internal controls over financial reporting as of December 31, 2025.
• The audit report confirms material compliance with U.S. GAAP and effective internal controls, reducing the risk for accounting-related surprises.
• No errors or restatements were noted in the period, and no recovery analysis for incentive-based compensation was triggered.

Other Notable Shareholder Information

• Otter Tail Corporation is a well-known seasoned issuer and a large accelerated filer.
• All required reports have been timely filed, and the company is not a shell company.
• No emerging growth company exemptions were elected.
• There are no documents incorporated by reference in this amendment.
• The amendment was solely to correct the audit report date and add updated certifications from the CEO and CFO as required by SEC rules.

Potential Price-Sensitive Information and Investor Considerations

• Regulatory risk remains a key consideration: The company’s earnings and asset values are significantly influenced by regulatory outcomes. Any adverse regulatory decision could impact the ability to fully recover investments or earn expected returns, which is a material risk for investors.
• Strong cash position and equity base: The company’s solid liquidity, growing asset base, and rising retained earnings indicate financial strength.
• No correction to previously reported financials other than the audit report date: There is no new or restated financial data in this amendment.

Conclusion

Bottom Line: The amendment does not introduce new financial information or corrections that would directly impact Otter Tail Corporation’s share price. The most notable investor-relevant issue remains the ongoing regulatory risk inherent in the company’s utility operations and the potential for future rate cases to affect profitability. The company’s financial position remains strong, and the clean audit opinion provides additional assurance to shareholders.
