SUMMARY

• Produced annual diluted earnings per share of $6.55.
• Achieved a consolidated return on equity of 16% on an equity ratio of 63%.

CEO OVERVIEW

"We are pleased with our 2025 financial results as they exceeded our expectations for the year,” said President and CEO Chuck MacFarlane. “Our results are fueled by our team members’ efforts, and I am proud of the ways they delivered for our customers and shareholders amidst dynamic market conditions.

“Throughout 2025, Otter Tail Power navigated a full agenda and our team members rose to the occasion. We made significant progress on a number of our capital projects, including our wind repowering, solar development and large regional transmission projects, all while executing on our regulatory priorities. We filed rate cases in South Dakota and Minnesota for the first time since 2018 and 2020, respectively. Even with the proposed increases, Otter Tail Power will continue to have some of the lowest electric rates in the region and country.

“Otter Tail Power’s capital spending plan for 2026 through 2030 remains robust. We have identified a pipeline of high-quality projects that provide safe, reliable and increasingly clean electric service for our customers. We are reaffirming our five-year rate base compounded annual growth rate of 10 percent.

“Our Manufacturing segment businesses continued to face soft end market demand following a sharp decline in sales volumes beginning in the third quarter of 2024. Our team members did an excellent job aligning our cost structure with the current demand environment while ensuring we remained well-positioned to respond when conditions improved. This positioning became important towards the end of 2025 as customer order activity picked up, enabling us to end the year with momentum.

“Our Plastics segment businesses continued to provide significant value to our organization even as segment earnings receded from record levels last year, and I am proud of how our team members navigated these changing market conditions. We benefitted from increased sales volumes enabled by the incremental production capacity and large-diameter capability added at Vinyltech in late 2024, partially offsetting the impact of lower PVC pipe sales prices. We expect to complete the second phase of our Vinyltech expansion project in early 2026.

“We are initiating our 2026 diluted earnings per share guidance range of $5.22 to $5.62 and affirming our long-term financial targets. The fundamentals of our business and diversified portfolio remain strong and we are confident in our ability to deliver on our growth plan for the benefit of our customers and shareholders. We continue to target a long-term earnings per share growth rate of 7 to 9 percent, resulting in a total shareholder return of 10 to 12 percent.”

CASH FLOWS AND LIQUIDITY

Our consolidated cash provided by operating activities was $386.0 million in 2025, compared to $452.7 million in 2024. The decrease was primarily driven by higher working capital requirements, including the timing of fuel cost and rider recoveries from our utility customers, and lower earnings.

Investing activities during the year included capital expenditures of $288.1 million. These expenditures were primarily within our Electric segment and included investments in our wind repowering initiatives, solar facilities, and other projects.

Financing activities in 2025 included the issuance of $100.0 million of long-term debt at Otter Tail Power, with the proceeds used to repay short-term borrowings, fund capital investments, and support operating activities. Other financing activities during the year included dividend payments of $88.1 million.

As of December 31, 2025, we had $319.3 million of available liquidity under our credit facilities and $386.2 million of available cash and cash equivalents, for total available liquidity of $705.5 million.

ANNUAL SEGMENT OPERATING RESULTS

Electric Segment

The following table shows heating and cooling degree days as a percent of normal.

The following table summarizes the estimated effect on diluted earnings per share of the difference in retail kilowatt-hour (kwh) sales under actual weather conditions and expected retail kwh sales under normal weather conditions in 2025 and 2024.

Operating Revenues increased $42.2 million largely due to increased fuel recovery revenues, recovery of our rate base investments, increased residential and commercial sales volumes, and the impact of favorable weather compared to last year. The increase in fuel recovery revenue was driven by increased customer demand as well as higher market energy and natural gas prices. These factors were partially offset by a net decrease in rider revenues resulting from higher production tax credits during the year following the completion of certain of our wind repowering projects and the commencement of tax credit generation which decreased income tax expense and offset rider revenue. These credits are passed through to customers, reducing operating revenue.

Net Income increased $6.6 million primarily due to higher retail revenues, as discussed above, and lower operating and maintenance expenses. These items were partially offset by higher depreciation and interest expense related to our rate base investments and the associated financing costs. In addition, a decrease in pension and postretirement related gains further offset the increase in operating revenues and decrease in operating and maintenance expenses.

Manufacturing Segment

Operating Revenues decreased $28.0 million primarily driven by a 6% decline in sales volumes, with reductions across several end markets, including agriculture, lawn and garden and recreational vehicles. Sales volumes were negatively affected by soft demand and inventory management efforts by manufacturers and dealers throughout much of the year, continuing a trend that began in the third quarter of 2024. A 1% decrease in steel costs, which are passed through to customers, also contributed to the decrease in operating revenues.

Net Income decreased $2.2 million primarily driven by lower sales volumes, as described above, and higher general and administrative expenses. These impacts were partially offset by higher profit margins from improved production efficiencies and reduced production costs, as we continue to align our cost structure with current demand levels.

Plastics Segment

Operating Revenues decreased $40.7 million primarily driven by a 15% decline in average sales prices compared to last year. Prices have been declining for several years after peaking in late 2022. The impact of lower sales prices was partially offset by an 8% increase in sales volumes, largely driven by additional production capacity following the completion of the first phase of our expansion project at Vinyltech in late 2024.

Net Income decreased $30.3 million as a result of decreased sales prices, as described above, partially offset by a 14% decrease in PVC resin and other input material costs and the 8% increase in sales volumes.

Corporate

FOURTH QUARTER OPERATING RESULTS

Consolidated Results

Electric Segment

Electric segment net income was $26.4 million, a $4.9 million increase from the fourth quarter of 2024. The increase was primarily driven by lower operating and maintenance expenses, higher residential and commercial sales volumes, and the impact of favorable weather compared to the same period last year. These benefits were partially offset by higher depreciation and interest expense associated with our rate base investments and related financing costs.

Manufacturing Segment

Manufacturing segment net income was $2.6 million, an increase of $3.2 million from a net loss of $0.6 million in the fourth quarter of 2024. The increase was primarily driven by an 11% increase in sales volumes and improved profit margins compared to the same period in the prior year. For much of the year, sales volumes were impacted by soft end market demand and inventory destocking by manufacturers and dealers. In the fourth quarter, however, sales volumes increased as customers began replenishing inventories. These favorable impacts were partially offset by higher general and administrative expenses compared to the prior year.

Plastics Segment

Plastics segment net income was $30.4 million, an $8.6 million decrease from the fourth quarter of 2024. The decrease was primarily driven by lower sales prices, which continued to decline throughout the year and were 20% lower in the fourth quarter compared to the same period last year. The impact of lower sales prices was partially offset by decreases in PVC resin and other input material costs and by higher sales volumes. The cost of input materials, including PVC resin, decreased 22% largely due to global supply and demand dynamics. Sales volumes increased 4% compared to the same period last year, largely driven by our increased production capacity.

Corporate

Corporate net loss was $7.6 million, an increase of $2.6 million from the net loss of $5.0 million in the fourth quarter of 2024. This increase was primarily the result of higher income tax expense, driven by higher state income taxes compared to last year.

2026 OUTLOOK

We anticipate 2026 diluted earnings per share to be in the range of $5.22 to $5.62. We expect our earnings mix in 2026 to be approximately 49% from our Electric segment and 51% from our Manufacturing and Plastics segments, net of corporate costs. Our anticipated earnings mix in 2026 deviates from our long-term expected earnings mix of 70% Electric and 30% Non-Electric as we expect Plastics segment earnings to remain elevated in 2026 compared to our long-term view of normal earnings for this segment.

The segment components of our 2026 diluted earnings per share guidance compared with actual earnings for 2025 are as follows:

The following items contribute to our 2026 earnings guidance:

Electric Segment - We expect segment earnings to increase 14% in 2026 based on the following:

• Returns generated from an increase in average rate base of 14% in 2026.
• Interim revenues commencing January 1, 2026 from our general rate case filed in Minnesota and anticipated final rates from our South Dakota general rate case.
• Increased operating and maintenance expenses from higher labor costs, planned outage costs at Big Stone Plant, and investments to promote system reliability.
• Increased depreciation and interest expense from our capital investments and associated financing.

Manufacturing Segment - We expect segment earnings to increase 7% in 2026 based on the following assumptions:

• Flat to modest increase in sales volumes in our contract metal fabrication business as conditions in certain end markets remain challenged.
• Increased sales volumes of horticulture products from improved end market conditions.
• Improved productivity partially offset by inflationary cost increases.

Plastics Segment - We expect segment earnings to decline 36% in 2026 based on the following assumptions:

• Continued decline in average product sales prices throughout 2026, as pricing continues to recede from the high point in 2022.
• Increased sales volumes from the new capacity added at our Phoenix facility, partially offset by a subdued housing market.
• Flat raw material costs in 2026 compared to 2025 as global supply and demand factors for PVC resin appear supportive of current pricing.

Corporate Costs - We expect our corporate costs to increase primarily from lower investment income and higher labor costs.

CAPITAL EXPENDITURES

The following provides a summary of actual capital expenditures for the year ended December 31, 2025, and anticipated annual capital expenditures for the next five years, along with average rate base and annual rate base growth of our Electric segment:

Our updated five-year capital expenditure plan includes Electric segment investments in solar and battery storage resources, transmission and distribution assets, and investments in system reliability and technology. Our Electric segment capital expenditure plan produces a compounded annual growth rate on average rate base of 10% over the next five years and will serve as a key driver in increasing Electric segment earnings over this timeframe. Our capital expenditure plan in our Manufacturing and Plastics segments includes a mix of investments to replace and upgrade existing equipment and investments to add additional capacity or productivity to our operations.
