Board of Directors Declares Quarterly Dividend of $0.39 Per Share

Otter Tail Corporation (Nasdaq: OTTR) today announced financial results for the quarter ended September 30, 2021.

SUMMARY

Compared to the quarter ended September 30, 2020:

• Consolidated operating revenues increased 34.2% to $316.3 million.

• Consolidated net income increased 46.8% to $52.8 million primarily driven by strong Plastics segment performance resulting from unique market conditions.

• Diluted earnings per share increased 44.8% to $1.26 per share.

The corporation increases its 2021 diluted earnings per share guidance range to $4.05 to $4.20 reflecting a range of 73% to 79% growth from 2020 reported diluted earnings per share of $2.34.

CEO OVERVIEW

“Otter Tail Corporation, through the efforts of our employees, achieved outstanding financial results during the third quarter of 2021,” said President and CEO Chuck MacFarlane. “Our Plastics segment continues its outstanding year as we capitalize on unique industry supply and demand conditions. PVC resin supply constraints began from the extreme cold weather in February which caused resin suppliers to temporarily close various petrochemical plants in the Gulf Coast region and was exacerbated in the third quarter of 2021 from disruptions caused by Hurricane Ida. These supply constraints, along with strong customer demand, have led to low PVC pipe inventories leading to high PVC pipe prices and margins at levels not previously experienced. We expect these supply and demand conditions to persist for the remainder of 2021 and continue during the first half of 2022. We currently expect these conditions to subside beginning in the second half of 2022.

“Electric segment earnings were down from the third quarter 2020 primarily due to increased costs arising from planned major maintenance at Big Stone Plant. Manufacturing segment earnings improved from the third quarter in 2020 primarily as a result of strong horticultural end market performance at T.O. Plastics.

“Otter Tail Power filed its Integrated Resource Plan in September. The requests in the five year action plan include the addition of dual fuel capability at our Astoria Station natural gas plant, the addition of 150 MW of solar generation in 2025 and the commencement of the process to withdraw from our 35 percent ownership in Coyote Station by December 31, 2028. After incorporating the requests from the Integrated Resource Plan, we now anticipate capital expenditures in our Electric segment of nearly $1 billion over the next five years, which will result in a compounded annual growth rate in rate base of 7.2% from the end of 2020 to the end of 2026.

“We continue to make progress on the development of Otter Tail Power’s 49.9 MW Hoot Lake Solar project, which will be constructed on and near the retired Hoot Lake Plant property in Fergus Falls, Minnesota. The project is expected to be completed in 2023 and has received renewable rider eligibility approval in Minnesota. The location of Hoot Lake Solar offers us a unique opportunity to utilize our existing Hoot Lake transmission rights, substation and land. We continue to experience supply chain challenges, including inflationary costs associated with the project.

“Our investments in Hoot Lake Solar, those identified in our Integrated Resource Plan and other capital expenditure plans allow us to improve our customers’ experience, reduce operating and maintenance expenses, reduce emissions and improve reliability and safety. Based on our current dispatch levels of Big Stone Plant and Coyote Station, we are targeting to reduce carbon emissions from our owned generation resources approximately 50 percent from 2005 levels by 2025 and 97 percent by 2050.

“Otter Tail Power received regulatory approval in the third quarter for the addition of a new load with a customer whose business is focused on the delivery of high performance crypto mining and infrastructure solutions to their customers and also engages in direct mining of Ethereum, Bitcoin and other crypto assets. Demand from this new customer is expected to be 100 MW with a high load factor and the ability to significantly curtail the load. We expect this load to be fully on line by the end of the first quarter of 2022.

“In September 2021, the Administrative Law Judge provided recommendations on our Minnesota Rate Case. The recommendations included a revenue decoupling mechanism and return on equity of 9.48% on a 52.5% equity layer. The Minnesota Public Utility Commission is expected to hold deliberations in early November with a written order issued by the end of January 2022. We expect final rates to be implemented by mid-2022.

“Our Manufacturing segment continues to be challenged by labor and recruitment costs as we focus on hiring to meet customer demand. We have made progress on hiring new employees during the quarter after increasing starting wages, off-shift premiums and sign-on incentives. We are focusing on getting these new employees to full productivity. Steel prices remain at historically high levels but lead times have started to improve. We remain focused on managing our steel supply to ensure we continue to receive material on time.

“Our Plastics segment experienced further resin supply constraints in the third quarter due to disruptions caused by Hurricane Ida. Resin shortages and low PVC pipe inventories negatively impacted our volume of pipe sold in the quarter. However, demand for PVC pipe remains strong and sales prices continue to increase because of these conditions and resulted in a record third quarter earnings.

“Our long-term focus remains on executing our growth strategies. For the utility, our strategy is to continue to invest in rate base growth opportunities and drive efficiency within our operating and maintenance expenses, which will lower our overall risk, create a more predictable earnings stream, maintain our credit quality and preserve our ability to pay dividends. Over time, we expect the electric utility business will provide approximately 70 percent of our overall earnings.

“The utility is complemented by well-run, strategic manufacturing and plastic pipe businesses, which provide organic growth opportunities from new products and services, market expansion and increased efficiencies. We expect these companies will provide approximately 30 percent of our earnings over the long term.

“We are increasing our 2021 earnings per share guidance to a range of $4.05 to $4.20 from our previous range announced in August 2021 of $3.50 to $3.65.”

QUARTERLY DIVIDEND

On November 1, 2021 the corporation’s Board of Directors declared a quarterly common stock dividend of $0.39 per share. This dividend is payable December 10, 2021 to shareholders of record on November 15, 2021.

CASH FLOWS AND LIQUIDITY

Our consolidated cash provided by operating activities for the nine months ended September 30, 2021 was $154.8 million compared with $141.3 million for the nine months ended September 30, 2020.

Investing activities for the nine months ended September 30, 2021 included capital expenditures of $117.3 million compared with $220.6 million for the nine months ended September 30, 2020. The decrease in capital expenditures was primarily related to Astoria Station and our Merricourt wind farm being under construction during 2020, with the capital spend being substantially complete for both projects by year-end 2020.

Financing activities for the nine months ended September 30, 2021 included net proceeds from short-term borrowings of $16.9 million and dividend payments of $48.6 million. The proceeds from short-term borrowings were primarily used to fund construction expenditures and support operating activities. Financing activities for the nine months ended September 30, 2020 included proceeds of $75.0 million from the issuance of long-term debt at Otter Tail Power Company, $42.6 million in net short-term borrowings and $35.2 million from the issuance of common stock. Proceeds from these debt and equity issuances were used to fund construction program expenditures in 2020. We paid $45.1 million in dividends during the nine months ended September 30, 2020.

On September 30, 2021, Otter Tail Corporation entered into a Fourth Amended and Restated Credit Agreement and Otter Tail Power Company entered into a Third Amended and Restated Credit Agreement, amending and restating the previously existing credit agreements to extend the maturity date of each agreement to September 30, 2026. The borrowing capacity and other significant terms of the agreements remained unchanged from the previous credit agreements.

The following table presents the status of the corporation’s lines of credit at September 30, 2021 and December 31, 2020:

SEGMENT PERFORMANCE

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 2021 and 2020.

Retail Revenues decreased $3.2 million primarily due to the following:

• The recognition of $2.6 million of Minnesota transmission rider revenue in the third quarter of 2020 resulting from a favorable judicial decision regarding the state jurisdictional treatment of federally approved transmission projects.
• A $1.2 million decrease in fuel recovery revenues largely due to lower purchased power costs and credits provided to retail customers from increased margins on wholesale sales, but partially offset by increased recovery of higher production fuel costs.
• A decrease in revenue from the combination of reduced demand from residential and commercial and industrial customers, exclusive of the impact of weather, net of the effect of a change in customer usage mix.

These decreases in revenue were partially offset by a $1.2 million increase in consumption from the favorable impact of weather in the third quarter of 2021 compared to the same period last year.

Transmission Services Revenues increased $1.0 million primarily due to increased generator interconnection revenues.

Wholesale Revenues increased $5.4 million as a result of a 129.5% increase in wholesale sales volumes and a 101.7% increase in wholesale prices driven by increased fuel costs and market demand for wholesale energy.

Production Fuel costs increased $6.1 million mainly as a result of a 41.4% increase in kwhs generated from our fuel-burning plants due to higher demand and favorable prices for energy in wholesale markets. In addition, increased fuel cost per kwh also contributed to higher production fuel costs in the third quarter of 2021.

Purchased Power costs to serve retail customers decreased $3.6 million primarily due to a 48.9% decrease in the volume of purchased power as our recent capacity additions provide additional generation resources to serve customer demand and market conditions led to operating our existing facilities at higher capacity factors in lieu of purchasing power at higher market prices, but partially offset by an increase in the cost of purchased power per kwh in the third quarter of 2021.

Operating and Maintenance Expense increased $3.6 million mainly due to:

• $1.4 million of Merricourt and Astoria Station operating and maintenance expenses incurred in the third quarter of 2021 as these facilities are now commercially operational.
• $2.1 million of maintenance costs arising from our planned outage at Big Stone plant, which began in the third quarter of 2021 and we expect will be completed in the fourth quarter of the year.
• Other additional expenses include an increase in transmission tariff expense from higher transmission volumes and increased travel costs as business travel recovers from the impact of COVID-19.

These expense increases were partially offset by, among other items, lower operating costs following the closure of Hoot Lake Plant in May 2021 and lower bad debt expense due to improving customer collections as the economic impact of COVID-19 has eased.

Depreciation and Amortization expense increased $2.2 million primarily due to Merricourt and Astoria Station being placed in service in the fourth quarter of 2020 and the first quarter of 2021, respectively.

Interest Charges increased $1.1 million primarily due to additional interest expense from a $40.0 million long-term debt issuance in August 2020, a higher level of short-term debt borrowings outstanding in 2021 and a lower level of capitalized interest due to the completion and placement in service of Astoria Station in the first quarter of 2021.

Other Income decreased $0.8 million driven by lower allowance for equity funds used during construction due to the completion of Astoria Station in the first quarter of 2021.

Income Tax Expense decreased $4.4 million primarily due to earning production tax credits on Merricourt generation in 2021. The tax benefits of these credits are passed through to retail customers in each of our jurisdictions.

Manufacturing Segment

Manufacturing segment revenues and net income increased $30.1 million and $0.9 million, respectively. The increase in revenues was primarily due to a 41.3% increase in material costs at BTD, which is passed through to customers, as steel prices increased significantly from the previous year. Steel prices have increased as steel mill production has not matched customer demand as mill capacity recovers from shutdowns in 2020 resulting from the COVID-19 pandemic. A 4.0% increase in sales volumes and an increase in scrap revenues, primarily due to higher scrap metal prices, also contributed to the increase in operating revenues.

The increase in operating revenues at BTD were largely offset by lower gross profit margins and increased operating costs. Gross profit margins were negatively impacted by lower productivity and increased labor and freight costs. The lower level of productivity during the period was primarily the result of recent increases in headcount and the time required for new employees to achieve peak productivity. The increase in operating expenses in the third quarter of 2021 was the result of increased incentive based compensation and other costs necessary to support higher business volumes.

Segment operating revenues and net income also benefited from increased product pricing and higher levels of horticulture sales at T.O. Plastics, along with increased gross profit margins resulting from higher production volumes.

Plastics Segment

Plastics segment revenues and net income increased $46.8 million and $18.1 million, respectively. The price per pound of polyvinyl chloride (PVC) pipe sold continued to increase, as it has throughout 2021, increasing 103.6% in the third quarter of 2021 compared to the same period last year and exceeding the 91.7% increase in the cost of PVC resin and other input materials. The increase in sale prices was largely due to the combination of PVC resin supply constraints, which has led to limited PVC pipe inventory, and strong demand for PVC pipe products. Resin supply in the third quarter of 2021 was negatively impacted by disruptions caused by Hurricane Ida in the Gulf Coast region, which compounded supply constraints that began in the first quarter of 2021 as a result of plant shutdowns caused by extreme winter weather. Pounds of pipe sold in the third quarter of 2021 decreased 13.0% from the same period last year, as resin supply constraints limited our production.

Corporate Costs

Our corporate net loss in 2021 was consistent with the same period last year. Quarterly performance based compensation expense in the third quarter of 2021 was lower than the amount recognized in the same period last year. This change was partially offset by a decreased income tax benefit. The decreased income tax benefit was primarily the result of the decrease in losses before income taxes and changes related to non-taxable transactions impacting our estimated annual effective tax rate.

2021 BUSINESS OUTLOOK

We are increasing our 2021 diluted earnings per share guidance range to $4.05 to $4.20 in light of third quarter results and forecasts for the remainder of 2021 driven by expected performance in our Plastics segment. The midpoint of our revised 2021 earnings per share guidance of $4.13 per share reflects a 76% growth rate from 2020 diluted earnings per share of $2.34.

Segment components of our revised 2021 diluted earnings per share guidance range compared with 2020 actual earnings and prior guidance are as follows:

The following items contribute to our 2021 earnings guidance:

• We continue to maintain our Electric segment guidance from our May 3, 2021 earnings release.
• We continue to maintain our Manufacturing segment guidance from our August 2, 2021 guidance earnings release.
  • Steel lead times have improved somewhat during the third quarter and supply has become less of an issue. Despite these positive indicators, we remain focused on managing our steel supply to ensure we continue to receive material on time. We anticipate elevated steel prices will continue throughout the remainder of 2021 and into 2022. We continue to improve staffing levels to keep up with strong demand and to mitigate the impact of increasing expedited freight costs while maintaining or improving labor efficiencies.
  • Backlog for the manufacturing companies of approximately $90 million for 2021 compared with $59 million one year ago.
• We are increasing our previous 2021 guidance for our Plastics segment as operating margins during the first nine months have been higher than expected driven by unique market conditions. Unexpected PVC resin supply constraints arose from the extreme cold weather in February which caused resin suppliers to temporarily close various petrochemical plants. Supply constraints were further exacerbated in the third quarter due to the impacts from Hurricane Ida, which caused resin suppliers to again enforce force majeure contract provisions. This further contributed to continuing increases in PVC pipe prices and operating margins at levels not previously experienced in the industry. Pounds of pipe sold in 2021 are now expected to be slightly higher than 2020 driven by strong construction and municipal markets. Resin suppliers continued to enforce resin allocations to customers and increase prices for raw materials due to market conditions such as availability constraints related to feedstock supplies for resin and a strong export market that has higher resin prices than the domestic market. We currently expect the current supply and demand dynamics to continue for the remainder of 2021 and into 2022. We currently expect these conditions could moderate during the last half of 2022.
• We continue to maintain our Corporate cost center guidance from our August 2, 2021 earnings release.

CAPITAL EXPENDITURES

The following provides a summary of actual capital expenditures for the year ended December 31, 2020, and anticipated capital expenditures for the period 2021 through 2026, for our Electric segment, which incorporates our latest IRP filing, and non-electric businesses:

Our capital expenditure plan for the 2021 to 2026 time period includes Electric segment investments in system reliability, wind and solar resources, technology and distribution assets, and transmission assets. Our Electric segment investment plan produces a compounded annual growth rate in rate base of 7.2% from the end of 2020 to the end of 2026 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 include investments to bring additional capacity to our operations, providing an opportunity for organic growth within these segments.
