Otter Tail Corporation (NASDAQ:OTTR) today announced financial results for the quarter ended June 30, 2025.

SUMMARY

Produced diluted earnings per share of $1.85 in the second quarter of 2025.
Increased midpoint of 2025 earnings per share guidance by $0.38 to $6.26 per share.
Return on equity of 17% over the trailing twelve months.

CEO OVERVIEW

"We are pleased with our second quarter financial results," said President and CEO Chuck MacFarlane. "Across our businesses, our team members remain committed to our mission - delivering value through building strong electric and manufacturing platforms - amidst dynamic market conditions.

"During the second quarter, severe weather moved through Otter Tail Power's service territory, resulting in significant property and infrastructure damage, as well as tree loss. Approximately 30 percent of our customers experienced an interruption in electric service due to the storms. Our employees worked tirelessly to restore power to our customers as quickly and safely as possible.

"Beyond our storm response, Otter Tail Power continues to perform well, executing on our significant capital investment plan and regulatory priorities. We secured approval to directly assign and recover the capital investment for our two solar development projects from the Minnesota and South Dakota Commissions. We look forward to adding 345 MW of cost-effective solar generation to our portfolio to better serve our customers. Additionally, for the first time since 2018, we filed a request with the South Dakota Public Utilities Commission for permission to increase our electric rates by approximately $5.7 million.

"Our Manufacturing segment continues to navigate soft end market demand but remains well positioned to respond when market conditions improve. Our recently completed BTD Georgia facility is ramping up to full production capability and we look forward to being able to better serve our growing customers in the southeast.

"Plastics segment results outpaced our expectations for the second quarter. We continue to benefit from strong product demand and higher sales volumes as the sales prices of PVC pipe continue to recede.

"We are uplifting our 2025 diluted earnings per share guidance for the Plastics segment, increasing our consolidated guidance to a range of $6.06 to $6.46 from our previous range of $5.68 to $6.08.

"Our strategic diversification continues to serve us and our stakeholders well even as we return to more normalized levels of Plastics segment earnings, generating incremental cash for us to reinvest into our significant utility rate base growth plan. We remain confident in our ability to deliver on our investment targets, producing an earnings per share growth of 6 to 8 percent."

QUARTERLY DIVIDEND

On August 4, 2025, the corporation's Board of Directors declared a quarterly common stock dividend of $0.525 per share. This dividend is payable September 10, 2025 to shareholders of record on August 15, 2025.

CASH FLOWS AND LIQUIDITY

Our consolidated cash provided by operating activities for the six months ended June 30, 2025 was $159.4 million compared to $223.5 million for the six months ended June 30, 2024, with the decrease primarily due to the timing of fuel cost and rider recoveries from our utility customers and the timing of payments for operating costs, as well as a decrease in earnings.

Investing activities for the six months ended June 30, 2025 included capital expenditures of $124.2 million. Capital expenditures during the period were largely within our Electric segment, including investments in wind repowering, advanced metering infrastructure, and transmission line projects.

Financing activities for the six months ended June 30, 2025 included the issuance of $100.0 million of long-term debt at 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 six months ended June 30, 2025 also included net repayments of short-term borrowings totaling $69.6 million and dividend payments of $44.0 million.

As of June 30, 2025, we had $170.0 million and $211.0 million of available liquidity under our Otter Tail Corporation and Otter Tail Power credit facilities, respectively, along with $307.2 million of available cash and cash equivalents, for total available liquidity of $688.2 million.

Effect on Diluted Earnings Per Share

—

0.03

(0.03

)

Operating Revenues increased $15.9 million primarily due to increases in fuel recovery and rider revenues, and the impact of favorable weather compared to the same period last year. Increased fuel recovery revenue was primarily driven by an increase in the price of natural gas and the cost of market energy. Increased rider revenue was largely from the recovery of our investments in our wind repowering projects.

Net Income increased $0.7 million primarily due to the increase in revenues, as described above, partially offset by increased operating and maintenance expenses, including planned outage costs at Coyote Station, and increased depreciation and interest expense associated with our rate base investments.

Manufacturing Segment

	*Three Months Ended June 30,*
*(in thousands)*		*2025*	*2024*		*$ Change*			*% Change*
Operating Revenues	$	78,726	$	96,684	$	(17,958	)	(18.6	)%
Net Income		3,481		6,835		(3,354	)	(49.1	)

Operating Revenues decreased $18.0 million primarily due to a 9% decrease in sales volumes, with declines experienced across several end markets, including agriculture, recreational vehicles, lawn and garden, and construction. Sales volumes were down at our metal fabrication business due to soft end market demand and inventory management efforts by manufacturers and dealers. A 7% decrease in steel costs, which are passed through to customers, also contributed to the decrease in operating revenues.

Net Income decreased $3.4 million primarily due to lower sales volumes and enhanced profit margins in the second quarter of 2024, which benefited from the positive impact of the timing of pass-through steel cost fluctuations and the selling of lower cost inventory. The impacts of decreased operating revenues and profit margins were partially offset by a decrease in general and administrative costs.

Plastics Segment

	*Three Months Ended June 30,*
*(in thousands)*		*2025*		*2024*	*$ Change*			*% Change*
Operating Revenues	$	125,586	$	132,824	$	(7,238	)	(5.4	)%
Net Income		53,104		60,612		(7,508	)	(12.4	)

Operating Revenues decreased $7.2 million primarily due to a 15% decrease in sales prices compared to the same period last year, continuing the steady decline in product pricing from peak market conditions in late 2022. The impact of decreased sales prices was partially offset by an 11% increase in sales volumes, driven by strong distributor and end-market demand for our products, coupled with increased production capacity following the completion of our expansion project at Vinyltech in late 2024. Active infrastructure investment and construction activity across our sales territories continue to contribute to strong demand for our products.

Net Income decreased $7.5 million primarily due to decreased sales prices, as described above, partially offset by the 11% increase in sales volumes and a 15% decrease in PVC resin cost driven by global supply and demand dynamics which continues to result in elevated supply.

2025 OUTLOOK

We are increasing our 2025 diluted earnings per share guidance to a range of $6.06 to $6.46. We expect our earnings mix in 2025 to be approximately 37% from our Electric segment and 63% from our Manufacturing and Plastics segments, net of corporate costs. Our anticipated earnings mix in 2025 deviates from our long-term expected earnings mix of 65% Electric / 35% Non-Electric as we expect Plastics segment earnings to remain elevated in 2025 compared to our long-term view of normal earnings for this segment.

The segment components of our 2025 diluted earnings per share guidance compared with actual earnings for 2024 are as follows:

				*2025 EPS Guidance*						*2025 EPS Guidance*
	*2024 EPS*			*February 17, 2025*						*August 4, 2025*
	*by Segment*			*Low*			*High*			*Low*			*High*
Electric	$	2.16		$	2.29		$	2.35		$	2.29		$	2.35
Manufacturing		0.33			0.21			0.27			0.21			0.27
Plastics		4.77			3.26			3.50			3.64			3.88
Corporate		(0.09	)		(0.08	)		(0.04	)		(0.08	)		(0.04	)
Total	$	7.17		$	5.68		$	6.08		$	6.06		$	6.46
Return on Equity		19.3	%		13.8	%		14.6	%		14.5	%		15.3	%

We are maintaining our earnings guidance for our Electric and Manufacturing segments and maintaining our Corporate cost outlook. We are increasing our Plastics segment earnings guidance based on:

Better than expected financial results in the second quarter of 2025,
Lower material costs anticipated for the remainder of the year, as the forecasted price of PVC resin has declined, and
Revised expectations for PVC pipe pricing for the second half of the year.
