Otter Tail Corporation Announces Note Purchase Agreement and New Financial Obligations

Key Points for Investors:

• Otter Tail Corporation (OTTR) has entered into a significant Note Purchase Agreement as of March 19, 2026, between Otter Tail Power Company and several named purchasers.
• This agreement establishes new direct financial obligations for Otter Tail Corporation that may influence the company’s capital structure, liquidity, and financial flexibility.
• The agreement is structured as a private placement, not subject to public securities registration, and is aimed at sophisticated institutional investors.
• The newly issued notes are senior unsecured debt, which will rank pari passu with all other senior unsecured indebtedness of the company.
• Key financial covenants include a limitation on interest-bearing debt (not to exceed 65% of total capitalization) and a cap on priority indebtedness (not to exceed 20% of total capitalization) as measured at the end of each fiscal quarter.
• Comprehensive reporting and disclosure requirements are included, with the company committing to provide detailed quarterly and annual financial statements, officer certifications, and other material updates to noteholders and institutional investors.
• The agreement includes investor protections such as mandatory prepayment options for holders in the event of a Change of Control, and provisions for make-whole amounts if the company opts for early prepayment.
• Use of proceeds from the notes will follow the plans described in the company’s Offering Letter, with explicit commitments not to use proceeds for margin stock investments, thereby limiting regulatory risk exposure.
• The company also agreed to maintain robust internal controls, compliance with applicable laws and environmental regulations, and to avoid transactions with affiliates unless they are on arm’s length terms and in the ordinary course of business.

Details Investors Should Note

1. New Debt Issuance and Capital Structure Impact
The Note Purchase Agreement represents a new, senior unsecured debt issuance by Otter Tail Corporation, which may affect the company’s leverage ratios and financial risk profile. The company’s commitment to keep interest-bearing debt below 65% and priority debt below 20% of total capitalization is a critical covenant. It provides comfort to investors that the company will not become excessively leveraged, but also signals management’s plans for prudent capital management and financial discipline.

2. Stringent Reporting and Disclosure Requirements
Otter Tail is required to provide comprehensive financial information to noteholders, including quarterly and annual consolidated financial statements (prepared in accordance with GAAP), officer certifications attesting to covenant compliance, and timely updates on any material events, regulatory matters, or litigation that could affect the company’s financial condition. These requirements ensure transparency and accountability, but also mean that any negative developments will be quickly communicated to sophisticated investors, which could impact market perceptions and share price.

3. Change of Control and Prepayment Provisions
A material provision for investors is the “Change of Control” clause. Should a change of control occur, affected noteholders have the right to require the company to prepay their notes. This could have significant financial implications for Otter Tail during periods of corporate activity (such as M&A), and may influence the company’s future strategic flexibility.

4. Use of Proceeds and Regulatory Commitments
The company has explicitly committed that proceeds from the notes will not be used for margin stock purchases or speculative trading in securities, reducing potential regulatory risk. The company also affirms compliance with all environmental, safety, and other applicable laws, and commits to maintain stringent internal controls and transparent financial reporting.

5. Affiliate Transactions and Governance
The agreement restricts transactions between Otter Tail and its affiliates, requiring that any such transactions be in the ordinary course of business and on arm’s length terms. This is an important governance safeguard and reduces the risk of value-leakage or potential conflicts of interest that may harm shareholders.

Potential Price Sensitive Information

• The increase in senior unsecured debt may impact Otter Tail’s credit profile and cost of capital.
• Financial covenants provide downside protection for creditors, but may constrain management’s financial flexibility in the future.
• The detailed reporting requirements mean that any deterioration in the company’s financial performance, regulatory compliance, or material litigation will be promptly disclosed and could drive share price volatility.
• The Change of Control clause could affect the company’s attractiveness as an M&A target or its ability to engage in strategic transactions.

Shareholder Considerations:
Shareholders should closely monitor Otter Tail’s leverage ratios, compliance with new debt covenants, and the company’s ability to maintain its investment grade profile. Any breach of these covenants or material adverse events could trigger technical defaults, mandatory prepayments, or other actions that may adversely affect share value. Furthermore, the obligation to maintain robust internal controls and transparency is positive, but also means that any negative news will be rapidly disseminated to the market.
