Press Release

FERGUS FALLS, Minnesota - Otter Tail Corporation (Nasdaq: OTTR) today announced financial results for the quarter and year ended December 31, 2023.

Compared to the year ended December 31, 2022:

•Consolidated operating revenues decreased 8% to $1.3 billion.

•Consolidated net income increased 4% to $294.2 million.

•Diluted earnings per share increased 3% to $7.00 per share.

•The corporation achieved a consolidated return on equity of 22.1% on an equity ratio of 61.4%.

The corporation’s board of directors increased the quarterly common stock dividend to $0.4675 per share, an indicated annual dividend rate of $1.87 per share in 2024, a 7% increase from $1.75 per share in 2023.

“Otter Tail Corporation, through the efforts of our employees and the strength of our diversified business model, produced record earnings in 2023, beating the record set last year,” said President and CEO Chuck MacFarlane. "Electric segment earnings grew 6 percent compared to 2022, driven by the recovery of rate base investments and increased commercial and industrial sales. Manufacturing segment earnings increased modestly from 2022. Plastics segment earnings fell 4 percent from 2022 primarily due to a decrease in sales volumes. While Plastics segment earnings declined slightly from the extraordinary results produced in 2022, this segment continues to capitalize on favorable industry conditions and produce strong financial results compared to pre-2021 levels. A significant reduction in our corporate costs also drove 2023 earnings as we benefited from returns on our short-term investments funded by the significant cash flows our businesses have generated over the last three years.

“We continue to identify opportunities to reinvest in our businesses. In 2023, Otter Tail Power completed the purchase of Ashtabula III, a 62 MW wind facility, and placed Hoot Lake Solar, a 49 MW solar facility, into service. Expansion projects are underway for both BTD Manufacturing and Vinyltech as we add capacity to support our customers and future growth opportunities.

“We updated our Electric segment’s 5 year capital expenditure plan to $1.3 billion, an increase of approximately $200 million from our previous plan. Our updated plan is expected to produce rate base growth at a compounded annual rate of 7.7 percent.

“We ended 2023 in a position of financial strength, with a strong balance sheet and ample liquidity. We expect to fund our capital expenditures and fuel our earnings growth over the next five years without the need for additional equity financing.

“Our long-term focus remains unchanged - executing our strategy to grow our business 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 our objectives and to deliver on our financial targets, including producing a compounded annual growth rate in consolidated earnings per share of 5 to 7 percent over the long-term based on an earnings mix of approximately 65 percent from our Electric segment and 35 percent from our Manufacturing and Plastics segments.

“We are initiating our 2024 diluted earnings per share guidance range of $5.13 to $5.43. Our 2024 guidance reflects Electric segment earnings growth of approximately 7 percent and a decline in our Plastics segment earnings, driven by a continuing downward trend in sales prices and resin spreads, but partially offset by increased sales volumes. We expect declines in sales prices and resin spreads will occur throughout 2024 and into 2025.

Our consolidated cash provided by operating activities was a record $404.5 million in 2023, compared to $389.3 million in 2022, with the increase primarily due to a $10.0 million increase in net income and a decrease in pension plan contributions due to the plan's funded status, partially offset by an increase in working capital. Investing activities included capital expenditures of $287.1 million in 2023, primarily related to capital investments within our Electric segment, including the purchase of the Ashtabula III wind farm and investments in our Hoot Lake Solar and wind repowering projects. Financing activities in 2023 included net short-term borrowings of $73.2 million and dividend payments of $73.1 million.

As of December 31, 2023, we had $249.4 million of available liquidity under our credit facilities and $230.4 million of available cash and cash equivalents, for total available liquidity of $479.8 million.

Effect on Diluted Earnings Per Share			$	0.02					$	(0.09)					$	0.11

Operating Revenues decreased $21.3 million primarily due to decreased fuel recovery and wholesale revenues, and the impact of unfavorable weather, partially offset by increased commercial and industrial sales volumes and rider revenue. 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, largely driven by decreased fuel costs. Commercial and industrial sales volumes increased compared to the previous year as a result of increased demand, including a new commercial customer load in North Dakota added during 2022. The increase in rider revenue was driven by the recovery of costs from the acquisition of the Ashtabula III wind farm and our Hoot Lake Solar project, which were completed during the year.

Net Income increased $4.5 million primarily due to increased rider revenue, increased commercial and industrial sales, and lower pension and other postretirement benefit costs, partially offset by increased operating and maintenance expenses, increased depreciation expense, and the impact of unfavorable weather. Increased operating and maintenance expenses included strategic spending on customer reliability initiatives, increased labor and employee benefit costs, and increased insurance expenses.

Operating Revenues increased $4.8 million primarily due to a 12% increase in sales volumes at BTD Manufacturing (BTD), our contract metal fabricator, driven by strong end market demand in the construction, industrial, and agricultural segments. 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 an 11% decrease in material costs, which are passed through to customers. Operating revenues at T.O. Plastics, our plastics thermoforming manufacturer, decreased primarily due to decreased sales volumes of horticulture products, as order and delivery lead times for these products have begun to normalize after volatility experienced in the previous year and customers reduced their order demand and are beginning to return to normal seasonal buying patterns.

Net Income increased $0.5 million due to increased operating revenues at BTD, partially offset by lower sales volumes at T.O. Plastics, increased depreciation expense, and increased operating expenses due to inflationary cost pressures and increased variable operating costs.

Operating Revenues decreased $94.5 million primarily due to a 14% decrease in sales volumes. Sales volume decreases were attributable to softer end market demand coupled with distributor inventory management, as these customers reduced their inventory levels during the first half of the year after previously building higher inventory levels in response to market uncertainty and supply chain challenges. Operating revenue decreases were also the result of a 5% decrease in sales prices, as prices in 2023 decreased from record highs in 2022.

Net Income decreased $7.6 million due to decreased operating revenues, as described above, partially offset by an increase in gross profit margins, as decreases in the cost of PVC resin and other input materials outpaced decreases in sales prices.

Net Income at our corporate cost center increased $12.7 million, from a $12.1 million loss in the prior year primarily due to increased investment income earned on our short-term cash equivalent investments, lower health care costs related to our self-funded health insurance program, and investment gains from our corporate-owned life insurance policies.

Electric segment net income was $17.0 million, which was consistent with the fourth quarter of 2022. Compared to last year, operating revenues decreased primarily due to lower fuel recovery revenues driven by lower purchased power costs, the impact of unfavorable weather, and decreased transmission revenue, partially offset by an increase in rider revenue. Operating and maintenance expenses increased compared to last year including increases in labor and employee benefit cost, vegetative maintenance, and insurance expenses. The decrease in operating revenues and increase in operating and maintenance expenses were largely offset by lower pension and other postretirement benefit costs.

Manufacturing segment net income was $1.2 million, a $1.9 million decrease from the fourth quarter of 2022. The decrease was primarily due to decreased sales volumes of horticulture products at T.O. Plastics and increased operating expenses, partially offset by increased sales volumes and sales price increases implemented in response to labor and non-steel material cost inflation at BTD, as well as a $0.6 million increase in scrap revenues, driven primarily by higher scrap metal prices.

Plastics segment net income was $39.5 million, a $14.9 million increase from the fourth quarter of 2022, primarily due to a 59% increase in sales volumes. In the fourth quarter of 2022, demand for PVC pipe was lower as distributor customers strategically managed their inventory levels and made efforts to sell through higher-priced inventories. The increase in sales volumes was partially offset by decreased sales prices, as sales prices decreased 14% from the fourth quarter of 2022.

Corporate net income was $0.1 million, a $2.8 million increase from a $2.7 million loss in the fourth quarter of 2022, primarily due investment income earned on our short-term cash equivalent investments and lower health care costs related to our self-funded health insurance program.

We anticipate 2024 diluted earnings per share to be in the range of $5.13 to $5.43, with an earnings mix of approximately 41% from our Electric segment and 59% 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 we expect Plastics segment earnings to remain elevated in 2024 compared to our long-term view of normal earnings for this segment.

The segment components of our 2024 diluted earnings per share guidance compared with actual earnings for 2023 are as follows:

The following items contribute to our 2024 earnings guidance:

Electric Segment - We expect segment earnings to increase 7% over 2023 based on the following key assumptions:

•Normal weather conditions in 2024.

•Returns generated from an increase in average rate base of 8.5% in 2024, compared to 2023.

•Interim revenue increase, which commenced January 1, 2024, resulting from the general rate case filed in North Dakota.

•Lower operating and maintenance expenses driven by lower anticipated employee benefit cost and discretionary spending.

•Increased depreciation expense resulting from our capital expenditures.

•Increased interest expense from increased borrowings to fund our capital investments.

Manufacturing Segment - We expect segment earnings in 2024 to increase 4% over 2023 based on the following key assumptions:

•Higher sales volumes and favorable product mix, improved productivity and lower incentive costs at BTD, partially offset by continued cost pressures in the business.

•Product pricing pressures and increased manufacturing cost at T.O. Plastics driving a decline in earnings in 2024.

Plastics Segment - We expect segment earnings to decline in 2024 based on the following key assumptions:

•Anticipated margin compression resulting from a continued downward trend in product prices over the course of 2024.

•Increased sales volumes as distributor purchasing normalizes in 2024 after destocking and inventory management in 2023.

Corporate Costs - We anticipate corporate costs will increase in 2024 primarily due to the following:

•Lower anticipated market-based gains on our corporate investments.

•Expected increase in claims in our self-insured health plan.

•Lower incentive compensation cost.

•Higher earnings on cash equivalent investments from an anticipated increase in our average investment balance.

The following provides a summary of actual capital expenditures for the year ended December 31, 2023, and anticipated annual capital expenditures for the next five years, along with average rate base and annual rate base growth of our Electric segment:

Annual Rate Base Growth												7.3		%							8.5		%				10.1		%				5.8		%				6.8		%				7.2		%

Our updated capital expenditure plan for the next five years (2024-2028) includes Electric segment investments in wind and solar 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 7.7% over the next five years and will serve as a key driver in increasing Electric segment earnings over this timeframe.

Our previous five year capital expenditure plan (2023-2027) had a compounded annual growth rate on average rate base of 6.5%. Our capital expenditure plan in our Manufacturing and Plastics segments includes investments to bring additional capacity to our operations, which will provide an opportunity for organic growth within these segments.
