• Achieved a consolidated return on equity of 16% on an equity ratio of 63% in 2025.

Future Outlook

The company anticipates 2026 diluted earnings per share to be in the range of $5.22 to $5.62, with an expected earnings mix of approximately 49% from the Electric segment and 51% from the Manufacturing and Plastics segments. This deviates from the long-term expected mix of 70% Electric and 30% Non-Electric due to expected elevated Plastics segment earnings. The Electric segment earnings are projected to increase by 14% in 2026, driven by rate base growth and new interim rates. Manufacturing segment earnings are expected to increase by 7% with flat to modest sales volume increases. Plastics segment earnings are projected to decline by 36% due to continued price declines, partially offset by increased sales volumes from new capacity. The company reaffirms its long-term financial targets of 7-9% EPS growth and 10-12% total shareholder return.

Industry Context

StockSavvy.ai notes that the utility sector, represented by Otter Tail's Electric segment, typically offers stable, regulated returns, which is evident in the company's reaffirmed 10% rate base growth target and consistent capital investment in renewable generation and transmission. The challenges faced by the Manufacturing and Plastics segments, particularly soft end-market demand and declining PVC prices, reflect broader macroeconomic pressures and supply-demand dynamics impacting industrial and materials sectors. The strategic diversification helps mitigate risks from cyclical non-electric segments.

Comparison to Industry Standards

• The company's consolidated return on equity of 16% in 2025 is strong, potentially above the average for diversified utilities, which often range from 9-12%.
• The reaffirmed 10% compounded annual growth rate on average rate base for the Electric segment is competitive within the utility industry, indicating robust infrastructure investment plans.
• The decline in PVC pipe sales prices and soft demand in manufacturing end markets (agriculture, lawn and garden, recreational vehicles) aligns with broader industry reports of inventory destocking and demand normalization after pandemic-era highs, affecting companies like Westlake Chemical (WLK) or Advanced Drainage Systems (WMS) in the plastics/materials space, and various industrial manufacturers.
• The company's target long-term EPS growth rate of 7-9% and total shareholder return of 10-12% are ambitious and generally above the average for mature utility companies, suggesting confidence in their diversified strategy.

Stakeholder Impact

• Shareholders: Positive impact from 2025 results exceeding expectations and reaffirmed long-term growth targets, but potential concern from lower 2026 EPS guidance.
• Customers (Electric): Benefit from continued investments in safe, reliable, and increasingly clean electric service, and Otter Tail Power maintaining some of the lowest electric rates despite proposed increases.
• Employees: Efforts recognized by the CEO, and alignment of cost structure in the Manufacturing segment to current demand levels.
• Creditors: Issuance of $100.0 million long-term debt indicates continued access to capital markets.

Next Steps

• Completion of the second phase of the Vinyltech expansion project in early 2026.
• Anticipated final rates from the South Dakota general rate case.
• Host a live webcast on Tuesday, February 17, 2026, at 10:00 a.m. CT to discuss financial and operating performance.
• Continued capital investments in solar and battery storage resources, transmission and distribution assets, and system reliability and technology as part of the five-year capital expenditure plan.

Key Dates

Recommendation

While Otter Tail Corporation delivered strong 2025 results exceeding expectations and maintains robust long-term growth targets for its stable Electric segment, the significantly lower 2026 EPS guidance, driven by anticipated declines in the Plastics segment and increased corporate costs, presents a near-term headwind. The diversified business model offers resilience, but the non-electric segments face cyclical pressures. A "hold" recommendation reflects the balance between the strong utility fundamentals and the near-term earnings deceleration, suggesting investors monitor the execution of capital projects and the recovery of non-electric segment demand.
