Otter Tail Corporation Announces First Quarter Earnings and Affirms 2026 EPS Guidance
FERGUS FALLS, Minnesota - Otter Tail Corporation (Nasdaq: OTTR) today announced financial results for the quarter ended March 31, 2026.
SUMMARY
•Produced diluted earnings per share of $1.73 in the first quarter of 2026.
•Return on equity of 15% over the trailing twelve months.
•Affirmed 2026 diluted earnings per share guidance range of $5.22 to $5.62.
CEO OVERVIEW
"We are pleased with our first quarter financial results and are well positioned to achieve our financial objectives for the year,” said CEO Chuck MacFarlane. “Across our businesses, our team members executed on our near-term priorities for the benefit of our customers and shareholders.
“Otter Tail Power delivered on our regulatory priorities while making significant progress on our customer-focused rate base growth plan. We obtained approval of our fully settled South Dakota rate case in the first quarter and implemented our new base rates at the beginning of April. We also implemented interim rates at the start of the year for our ongoing Minnesota rate case.
“We completed our wind repowering project earlier this year on budget despite weather-related headwinds delaying the in-service timing. We continue to make progress on our solar, battery storage and large regional transmission projects. Our team members secured the solar panels needed for our two solar development projects during the first quarter, eliminating tariff-related risk and avoiding the potential cost increase for the benefit of our customers.
“We are pleased with the results produced by our Manufacturing segment businesses as our team members’ cost-management efforts over the past year positively contributed to our quarterly results. We are also encouraged by increasing sales volumes in several of our end markets.
“Our Plastics segment businesses benefitted from better-than-expected demand for our products while average sales prices continued to recede in line with our expectations. We completed the second phase of our Vinyltech expansion project earlier this year and look forward to leveraging the additional production capacity. With the conclusion of the second phase, this completes a multi-year expansion project that added 15 percent of additional production capacity, and increased manufacturing space and raw material storage capabilities. This investment will allow us to better serve our customers, pursue growth opportunities and enhance our employee experience.
“We are maintaining our 2026 diluted earnings per share guidance range of $5.22 to $5.62. The fundamentals of our diversified portfolio remain strong, and we are confident in our ability to deliver on our customer-focused growth plan over the long term. Our targeted long-term earnings per share growth rate is 7 to 9 percent, with a total shareholder return of 10 to 12 percent.”
QUARTERLY DIVIDEND
On May 4, 2026, the corporation’s Board of Directors declared a quarterly common stock dividend of $0.5775 per share. This dividend is payable on June 10, 2026 to shareholders of record on May 15, 2026.
CASH FLOWS AND LIQUIDITY
Our consolidated cash provided by operating activities for the three months ended March 31, 2026 was $70.6 million compared to $39.5 million for the three months ended March 31, 2025. The increase in cash provided by operating activities was primarily due to a decrease in working capital requirements, largely driven by the timing of vendor payments and the recovery of fuel cost and rider revenue from our utility customers.
Investing activities for the three months ended March 31, 2026 included capital expenditures of $185.3 million. Our capital investments were largely within our Electric segment and included investments in our solar, wind repowering and other projects.
Financing activities for the three months ended March 31, 2026 included the issuance of $100.0 million of long-term debt by Otter Tail Power; the proceeds of which were used to repay short-term borrowings, fund capital investments and support operating activities. Financing activities for the period also included net short-term borrowings totaling $7.7 million and dividend payments of $24.3 million.
As of March 31, 2026 we had $170.0 million and $140.5 million of available liquidity under our Otter Tail Corporation and Otter Tail Power credit facilities, respectively, along with $348.4 million of available cash and cash equivalents, resulting in total available liquidity of $658.9 million.

Operating Revenues increased $16.2 million driven by higher retail revenues due to increased rates, higher fuel recovery revenues, increased commercial sales volumes and the recovery of our investments through riders. These increases were partially offset by the impact of unfavorable weather and higher production tax credits, the benefit of which is provided to customers.
Interim rates in Minnesota and South Dakota became effective in January 2026 and December 2025, respectively, and updated base rates in North Dakota went into effect in March 2025. Higher fuel recovery revenues resulted from increased generation from our natural gas and coal-fired facilities. Finally, we benefited from the recovery of our significant rate base investments over the past twelve months, including investments in our wind repowering and solar facility projects.
Net Income increased $10.5 million primarily due to higher retail revenues, partially offset by higher operating and maintenance expenses, including increased labor costs, as well as higher depreciation and interest expense associated with our rate base investments.

Operating Revenues increased $7.9 million primarily due to a 5% increase in steel costs, which are passed on to customers, and a 4% increase in sales volumes. Demand improved in certain markets we serve, including the construction and recreational vehicle markets, compared to softer demand and tighter inventory management efforts during the same period last year.
Net Income increased $2.8 million primarily due to higher margins resulting from the mix of products sold, improved production efficiencies and a cost structure aligned with current demand levels. Higher sales volumes also contributed to the increase in earnings. The impact of higher margins and sales volumes was partially offset by higher general and administrative expenses.

Operating Revenues decreased $14.4 million primarily due to a 19% decrease in average sales prices compared with the same period last year, continuing the multi‑year decline in product pricing from peak levels in late 2022. This decrease was partially offset by a 7% increase in sales volumes. Sales volumes benefited from the opportunistic sale of specialty pipe during the period. Late in the quarter, we also benefited from distributor and contractor demand as they sought to secure inventories in advance of potential PVC resin cost increases.
Net Income decreased $10.5 million as a result of decreased sales prices, partially offset by the increase in sales volumes and a 12% decrease in PVC resin and other input material costs.

Net Income improved $1.7 million compared to the same period last year, primarily driven by a higher tax benefit and lower employee healthcare claims under our self-insured healthcare program. These improvements were partially offset by market-driven losses on our corporate-owned life insurance investments.
2026 OUTLOOK
We continue to 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.
