Press Release

FERGUS FALLS, Minnesota - Otter Tail Corporation (Nasdaq: OTTR) today announced financial results for the quarter ended September 30, 2023.

Compared to the quarter ended September 30, 2022:

•Consolidated operating revenues decreased 7% to $358 million.

•Consolidated net income increased 9% to $92 million.

•Diluted earnings per share increased 9% to $2.19 per share.

“Otter Tail Corporation, through the combined efforts of our employees and our diversified business model, delivered record setting quarterly earnings,” said President and CEO Chuck MacFarlane. Electric segment earnings were flat with the third quarter of 2022. Our Manufacturing segment produced earnings growth of 20 percent due to increased sales volumes and profit margins. Plastics segment earnings increased 6 percent primarily due to stronger operating margins as our sales price to resin spreads have improved compared to the third quarter of 2022.

“In August 2023, our 49 MW Hoot Lake Solar facility became fully operational. The project was completed and placed in service on time and on budget. Hoot Lake Solar was constructed on and near the retired Hoot Lake coal plant property in Fergus Falls, Minnesota and is the third largest operating solar site based on generation capacity in the state of Minnesota. With the completion of Hoot Lake Solar, we expect nearly 40 percent of Otter Tail Power’s owned and contracted energy generation will come from renewable resources.

“Otter Tail Power Company will file a request with the North Dakota Public Service Commission on November 2, 2023, for an increase in general rates in North Dakota. This request is largely driven by increases in our operating costs over the six years since our last rate case filing. We are proposing to increase net revenues by approximately $17 million, or 8.4 percent. Even with this increase, Otter Tail Power Company will continue to have some of the lowest rates in the country.

“We are increasing our 2023 diluted earnings per share guidance to a range of $6.76 to $6.96 from our previous range of $5.70 to $6.00. The increase in our guidance is primarily driven by stronger than expected Plastics segment earnings and revised expectations for the fourth quarter of the year.

“Our long-term focus remains unchanged - executing our strategy to grow our businesses and achieve operational, commercial and talent excellence to strengthen our position in the markets we serve. We believe our businesses are well-positioned to achieve these objectives and to deliver on our financial targets, including producing over the long-term a compounded annual growth rate in earnings per share of 5 to 7 percent based on an earnings mix of approximately 65 percent from our Electric segment and 35 percent from our Manufacturing and Plastics segments.”

On October 30, 2023, the corporation’s Board of Directors declared a quarterly common stock dividend of $0.4375 per share. This dividend is payable December 8, 2023 to shareholders of record on November 15, 2023.

Our consolidated cash provided by operating activities for the nine months ended September 30, 2023 was $318.5 million compared to $288.0 million for the nine months ended September 30, 2022. The increase was primarily due to the absence of a pension plan contribution in 2023 due to the plan's funded status, whereas a $20.0 million discretionary contribution was made in February 2022, and the timing of customer collections of forecasted fuel costs that will be adjusted in future periods. Increases to operating cash flows were partially offset by lower earnings. Investing activities for the nine months ended September 30, 2023 included capital expenditures of $229.8 million, primarily related to capital investments within our Electric segment including the purchase of the Ashtabula III wind farm for $50.6 million and investments in our Hoot Lake Solar facility and wind repowering projects. Financing activities for the nine months ended September 30, 2023 included net proceeds from short-term borrowings of $43.3 million at Otter Tail Power and dividend payments of $54.8 million.

As of September 30, 2023, we had $170.0 million and $108.9 million of available liquidity under our Otter Tail Corporation and Otter Tail Power Credit Agreements, respectively, along with $189.2 million of available cash and cash equivalents, for total available liquidity of $468.1 million.

The following table shows heating degree days (HDDs) and cooling degree days (CDDs) as a percent of normal.

			Three Months Ended September 30,
			2023						2022
HDDs			6.3		%				43.1		%
CDDs			92.2		%				108.4		%

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 2023 and 2022.

Operating Revenues decreased $12.4 million primarily due to a $13.2 million decrease in fuel recovery revenues, a decrease in wholesale revenues, and the impact of unfavorable weather, partially offset by increased renewable rider revenue and higher commercial and industrial sales in North Dakota. The decrease in fuel recovery revenues was primarily due to lower purchased power and fuel costs arising from decreased market energy costs and natural gas prices. Wholesale revenues decreased due to a decrease in wholesale electric prices driven by decreased fuel costs. Renewable rider revenue increases included recovery of costs related to the Ashtabula III wind farm and our Hoot Lake Solar project.

Net Income decreased $0.3 million primarily due to the impact of unfavorable weather, increased depreciation expense, and increased operating and maintenance expenses, driven by higher labor costs and strategic spending initiatives, partially offset by increased rider revenue, increased commercial and industrial sales, and lower pension costs.

Operating Revenues increased $1.9 million primarily due to an 8% increase in sales volumes at BTD Manufacturing driven by end market demand in the construction, recreational vehicle and power generation segments and incremental volumes from additional work with existing customers. Operating revenues also benefited from sales price increases implemented in response to labor and non-steel material cost inflation. Sales price increases and sales volume growth were partially offset by decreased steel prices, resulting in a 4% decrease in material costs, which are passed through to customers. Operating revenues at T.O. Plastics decreased primarily due to decreased sales volumes of horticulture products, as order and delivery lead times have normalized, and customers are working to reduce their inventory levels and return to more normal seasonal fluctuations.

Net Income increased $1.2 million primarily due to increased sales volumes and profit margins, as well as an increase in research and development tax credits at BTD, partially offset by decreased sales volumes at T.O. Plastics.

Operating Revenues decreased $15.3 million primarily due to an 11% decrease in sales prices compared to the same period last year. Sales prices have continued to decrease in the current year; however, they continue to remain elevated compared to pre-2021 levels. Sales volumes in the third quarter of 2023 were consistent with sales volumes during the same period last year.

Net Income increased $3.2 million primarily due to increased profit margins as our sales price to resin spreads improved compared to the third quarter of 2022. Resin and sales prices continued to decrease in the current year; however, the magnitude of sales price decreases was less than resin price declines. PVC resin and other input material costs decreased 39% compared to the same period last year as supply conditions improved, causing resin prices to decline over the last twelve months.

Net Income (Loss) at our corporate cost center increased primarily due to decreased employee benefit expenses, including decreases in our employee health insurance claim costs and increased investment income earned on our short-term cash equivalent investments.

We are increasing our 2023 diluted earnings per share range to $6.76 to $6.96. We expect our earnings mix in 2023, based on our updated guidance, to be approximately 30% from our Electric segment and 70% from our Manufacturing and Plastics segments, net of corporate costs. This anticipated mix deviates from our long-term expected earnings mix of approximately 65% Electric/35% non-electric as our Plastics segment continues to produce elevated earnings.

The segment components of our 2023 diluted earnings per share guidance compared with actual earnings for 2022 are as follows:

The following items contributed to our revised 2023 earnings guidance:

Electric Segment - We are tightening our range of expected earnings from our July 31, 2023 guidance and continue to expect our Electric segment to produce earnings growth of 6% over 2022.

Manufacturing Segment - We are increasing our Manufacturing segment guidance based on:

•The strength of third quarter earnings as sales volumes, margin improvement and tax credits drove earnings growth at BTD.

•Backlog for the manufacturing companies as of September 30, 2023 was approximately $107 million, compared with $141 million one year ago.

Plastics Segment - We are increasing our Plastics segment guidance based on:

•Continued strength in our product sales prices and related margins. While sales prices and margins have begun to recede from historic highs, the rate of decline continues to be slower than our previous expectations.

•Increased sales volume expectations as distributor inventory destocking is generally complete and demand has rebounded in advance of the seasonal decline anticipated in the latter part of the fourth quarter.

Corporate Costs - We are decreasing our Corporate cost guidance based on the following:

•The results in the third quarter of 2023 were better than expected due to higher balances of invested cash, higher yields on our cash investments and lower employee healthcare costs.

•Increased earnings on our cash balance investments over the remainder of the year due to a higher balance of invested funds and a higher yield.
