CEO Overview

“While we expected difficult business conditions in 2009, the impacts of the recession have become more widespread and significant than we had anticipated and now affect nearly all of our operating companies. Consequently, first quarter results fell below our expectations,” said John Erickson, president and chief executive officer of Otter Tail Corporation. “Compared to a year ago, our electric business faces reduced demand from industrial customers and lower demand and prices for power sold in the wholesale market. Our nonelectric businesses, particularly our manufacturing companies, are impacted by reduced orders from major customers as demand for their products has declined. This quarter’s year-over-year reductions in net income from our electric, plastics and manufacturing segments were partially offset by improved results from our other operating segments and reductions in corporate expenses.”

“We now expect the difficult economic conditions will last longer than we originally projected. In light of our first quarter results, and our expectation of continuing difficult economic conditions for the balance of the year, we are revising 2009 diluted earnings per share guidance to a range of $0.80 to $1.20 from our initial range of $1.10 to $1.50.

We have taken significant expense-reduction actions throughout the organization to mitigate the effects of the economic slowdown and will continue to closely monitor and appropriately manage our expense levels to address this business environment. We are grateful for the support and commitment from our employees across the organization, whose efforts to enhance efficiency, improve cash flow and better serve customers play a central role in preserving the strength of Otter Tail Corporation.”

Erickson concluded, “Although 2009 will be a challenging year, Otter Tail Corporation remains fundamentally strong, appropriately diversified and well-positioned for growth when the economy begins to recover. There are several bright spots worth noting. Earnings from our food ingredient processing segment improved in the first quarter of 2009 and we expect this to continue for the remainder of the year. Additionally, several of our operating companies have significant involvement in the wind-energy industry. Despite the slow economy and currently tight capital markets delaying wind-energy projects in 2009, we believe the prospects for wind-energy activity beyond 2009 are very positive, given the high level of support for renewable energy at both the federal and state levels. Finally, our consolidated cash flow from operations and our liquidity position continue to be strong, which gives us flexibility in managing through this environment.”

Cash Flow from Operations

The corporation’s cash flow from operations increased to $21.9 million for the quarter ended March 31, 2009 compared with $7.4 million for the quarter ended March 31, 2008, primarily driven by an improvement in working capital of approximately $10.6 million.

Otter Tail Corporation maintains a strong liquidity position, including amounts available under credit lines of $206.5 million; $137.7 million under the Otter Tail Power Company credit facility and $68.8 million under the Varistar Corporation credit facility as of March 31, 2009. The corporation believes it has the necessary liquidity to effectively conduct business operations for an extended period if current market conditions continue. “Despite the difficult economic conditions, the corporation maintains its commitment to a strong balance sheet and continues its focus on cash flow,” said Kevin Moug, chief financial officer of Otter Tail Corporation.

Cascade Investment

Cascade Investment, L.L.C. is the corporation’s largest shareholder, holding nearly 10% of the corporation’s outstanding common stock. A Special Committee of the Board of Directors has agreed to waive certain provisions of Minnesota law which impose limitations on business transactions between a publicly held Minnesota corporation and a shareholder that owns more than 10% of its common stock. The corporation has entered into a standstill agreement with Cascade whereby Cascade has agreed to limit its ownership of the corporation’s common stock to less than 20% of the outstanding common stock for a period of four years, except in certain circumstances. Erickson noted, “Cascade has been a large investor in the Otter Tail Corporation for nearly a decade and our relationship with Cascade has been very positive. We appreciate their long-term investment in our company and are pleased to have developed a framework with Cascade by which it will have an opportunity to increase its ownership in our corporation if it chooses to do so.”

Segment Performance Summary

Electric

Electric revenues and net income were $88.5 million and $8.5 million, respectively, for the quarter ended March 31, 2009 compared with revenues of $97.6 million and net income of $12.7 million for the quarter ended March 31, 2008. Retail electric revenues decreased 9.4% mainly due to the following:

• a $9.7 million decrease in fuel clause adjustment revenues related to a reduction in fuel and purchased power costs incurred to serve retail customers,

• a $1.0 million reduction in Minnesota retail revenues related to a final rate increase of 2.9% in effect in the first quarter of 2009 compared to an interim rate increase of 5.4% in effect in the first quarter of 2008, and

3

• a 10.6% decrease in kilowatt-hour (kwh) sales to industrial customers due to reduced demand by pipeline customers as a result of declining oil and natural gas prices.

These retail revenue decreases were partially offset by a $1.5 million increase in revenues related to increases in kwh sales to residential and commercial customers, increases in renewable resource recovery rider revenues of $1.5 million and a 4.1% interim rate increase in North Dakota. Fuel and purchased power costs related to retail use were down $3.3 million, despite the 2.3% increase in retail kwh sales. Fuel costs decreased as a result of generating less electricity from company-owned generators to serve retail load. Purchased power costs decreased, despite an increase in kwhs purchased, as a result of a 36.5% reduction in the cost per kwh of purchased power for retail use. Decreases in natural gas prices, increased output from regional hydroelectric plants, increased efficiency in wholesale electric markets and a decline in industrial demand for electricity are factors that have contributed to a significant decline in wholesale electric prices in 2009. The electric utility’s 59 wind turbines at Langdon and Ashtabula contributed to a reduction in fuel costs per kwh of generation by providing 9.0% of the electric utility’s total kwh generation in the first quarter of 2009.

Wholesale electric revenues from company-owned generation were $4.4 million for the quarter ended March 31, 2009 compared with $4.1 million for the quarter ended March 31, 2008 as a result of an increase in wholesale kwh sales that more than offset a 46.2% decrease in revenue per kwh sold. Fuel costs related to wholesale sales increased $0.4 million between the quarters. Net gains from energy trading activities, including net mark-to-market gains on forward energy contracts, were $1.4 million for the quarter ended March 31, 2009 compared with net gains of $1.7 million for the quarter ended March 31, 2008. Other electric operating revenues were down $0.8 million as a result of a $0.6 million decrease in revenues from contracted services and a $0.2 million reduction in transmission services related revenue. Electric operating and maintenance expenses were essentially unchanged. Depreciation expense increased $1.3 million mainly due to the construction of 32 wind turbines at the Ashtabula Wind Energy Center in 2008. There was also an increase in interest costs of $1.0 million.

Plastics

Plastics revenues and net loss were $13.5 million and $2.5 million, respectively, for the quarter ended March 31, 2009 compared with revenues of $22.3 million and net income of $0.6 million for the quarter ended March 31, 2008. The decrease in revenues and net income was due to an 18.8% decline in pounds of pipe sold combined with a 25.2% decrease in polyvinyl chloride (PVC) pipe prices. The lower profitability between the quarters was also impacted by the sell-off of higher priced finished goods inventory which adversely impacted operating margins. Significant reductions in new home construction in markets served by the plastic pipe companies have resulted in reduced demand and lower prices for PVC pipe products.

4

Manufacturing

Manufacturing revenues and net loss were $96.0 million and $1.1 million, respectively, for the quarter ended March 31, 2009 compared with revenues of $97.6 million and a net loss of $0.6 million for the quarter ended March 31, 2008.

• At DMI, revenues and net income increased $1.7 million and $2.0 million, respectively. In the first quarter of 2008, DMI’s results included costs of $0.8 million associated with the start up of DMI’s new plant in Oklahoma and lower than expected margins on a production contract at its Fort Erie plant of $3.2 million.

• At BTD, revenues increased $3.8 million. This increase reflects first quarter 2009 revenues of $5.2 million from Miller Welding, acquired in May 2008, offset by a $0.7 million decrease in sales volume and a $0.6 million decrease in scrap sales revenue related to a decrease in steel prices. The decline in sales volume and selling of higher-priced inventory in a constrained market contributed to a $1.0 million decrease in BTD’s net income between the quarters.

• At T.O. Plastics, revenues and net income decreased $4.6 million and $0.4 million, respectively, mainly due to a decrease in horticultural product sales as customers utilized existing inventory in the channel.

• At ShoreMaster, revenues and net earnings decreased $2.5 million and $1.1 million, respectively. The decline in earnings was due to the recognition of $1.8 million in product recall and testing costs and $0.9 million in additional losses on a marina construction project.

Health Services

Health services revenues and net loss were $28.2 million and $0.1 million, respectively, for the quarter ended March 31, 2009 compared with revenues of $29.3 million and a net loss of $0.7 million for the quarter ended March 31, 2008. Decreases in revenues of $0.9 million from scanning and other related services and $0.2 million from equipment sales and servicing were more than offset by decreases in costs of goods sold and operating expenses, resulting in a $0.6 million reduction in net losses. The imaging side of the business continues to be affected by less-than-optimal utilization of certain imaging assets.

Food Ingredient Processing

Food ingredient processing revenues and net income were $20.1 million and $1.4 million, respectively, for the quarter ended March 31, 2009 compared with revenues of $15.9 million and net income of $1.1 million for the quarter ended March 31, 2008. The $4.2 million increase in revenues is due to a 7.6% increase in pounds of product sold, combined with 17.4% increase in the price per pound of product sold. Cost of goods sold increased $3.7 million as a result of the increase in sales and a 20.5% increase in the cost per pound of product sold.

5

Other Business Operations

Other business operations revenues and net loss were $31.9 million and $0.3 million, respectively, for the quarter ended March 31, 2009 compared with revenues of $38.1 million and a net loss of $1.8 million for the quarter ended March 31, 2008. At the construction companies, revenues decreased $4.1 million while net income increased to $0.4 million compared to a net loss of $1.5 million for the same period a year ago. The increase in net income is a result of improved margins on construction projects. In the trucking operations, revenues decreased $2.1 million and net losses increased $0.5 million due to a significant reduction in miles driven directly related to the current economic recession.

Corporate

Corporate expenses, net-of-tax, were $1.6 million for the quarter ended March 31, 2009 compared with $3.2 million for the quarter ended March 31, 2008. The decrease reflects $2.0 million in expense reductions for general and administrative costs and a $0.4 million decrease in interest costs related to a reduction in corporate-held debt.

Income Taxes

The corporation’s effective income tax rate for the three months ended March 31, 2009 and 2008 was (46.0%) and 27.5%, respectively. The reduction from the federal statutory rate mainly reflects the benefit of production tax credits and North Dakota wind energy credits related to the electric utility’s wind turbines of approximately $2.1 million in the first quarter of 2009 and $0.6 million in the first quarter of 2008.

2009 Expectations

Otter Tail Corporation is revising its 2009 earnings guidance to be in a range of $0.80 to $1.20 per diluted share from its previously announced range of $1.10 to $1.50. The earnings guidance revision is reflective of the corporation’s expectations that difficult economic conditions will continue for the balance of the year. The revised earnings guidance is subject to risks and uncertainties given current global economic conditions and the other risk factors outlined below.

Contributing to the earnings guidance for 2009 are the following items:

• The corporation’s expectations for earnings from its electric segment have been revised downward due to the negative impact from continuing softness in demand from commercial and industrial customers and lower volumes and margins from wholesale energy sales. Declining demand along with the lowest natural gas prices in years is having a dramatic impact on the volume and price that can be realized from sales of excess generation into the marketplace. As a result, the corporation now expects earnings from its electric

6

segment to be lower in 2009 than in 2008. The corporation still expects increased levels of retail revenue from the electric segment in 2009 as a result of a 4.1% interim rate increase in North Dakota and increases in resource recovery rider revenue related to the Ashtabula Wind Energy Center that was placed in service in late 2008. The interim rate increase is part of a rate case filed with the North Dakota Public Service Commission (NDPSC) in November 2008 requesting a general annual rate increase of approximately $6.1 million, or 5.1%. Interim rates remain in effect for all North Dakota customers until the NDPSC makes a final determination on the electric utility’s request, which is expected to occur by August 1, 2009. Expectations in 2009 also reflect a request for an increase in revenues in South Dakota. A final decision on the request is expected from the South Dakota Public Utilities Commission in mid-summer 2009 with an interim rate increase going into effect in May 2009.

• The corporation expects the plastics segment’s 2009 performance to be below 2008 earnings given continued poor economic conditions. Previously announced capacity expansions are not expected to be brought on line until the economy improves and demand for PVC pipe increases.

• The corporation now expects earnings from the manufacturing segment to decline in 2009 as a result of the following:

o BTD Manufacturing saw unanticipated declines in customer demand in the first quarter of 2009 and expects the soft demand to continue for the rest of the year resulting in lower earnings compared with 2008.

o While the economy is expected to reduce the amount of spending on waterfront products, earnings are expected to improve at ShoreMaster compared with 2008 given the restructuring that has occurred in its business. While there continues to be uncertainty on the level of spending on residential products, ShoreMaster has implemented significant cost reductions across the organization, reduced capital spending and reorganized its business units for more efficient operations.

o At DMI Industries, the corporation expects a decline in earnings in 2009 due to wind developers’ limited access to financing which has resulted in cancellation or suspension of orders across the industry. Industry forecasts for megawatt installations of wind power in 2009 indicate a decrease of between 25 to 50 percent from 2008.

o T. O. Plastics’ earnings are expected to remain flat between the years. While it expects economic challenges, T.O. Plastics has implemented cost reductions and efficiency projects to maintain profitability.

o Backlog in place in the manufacturing segment to support revenues for the remainder of 2009 is approximately $152 million compared with $280 million one year ago.

7

• The corporation expects increased net income from its health services segment in 2009 as it focuses on improving its mix of imaging assets and asset utilization rates and has implemented cost reductions across the segment.

• The corporation expects increased net income from its food ingredient processing business in 2009 based on expectations of higher sales volumes, lower energy costs and higher production levels in 2009 compared with 2008.

• The other business operations segment is expected to have a similar level of earnings in 2009 compared with 2008. Backlog in place for the construction businesses is $85 million for the remainder of 2009 compared with $83 million one year ago.

• Corporate general and administrative costs are expected to decrease in 2009.

Risk Factors and Forward-Looking Statements that Could Affect Future Results

The information in this release includes certain forward-looking information, including 2009 expectations, made under the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995. Although the corporation believes its expectations are based on reasonable assumptions, actual results may differ materially from those expectations. The following factors, among others, could cause actual results for the corporation to differ materially from those discussed in the forward-looking statements:

• The corporation is subject to federal and state legislation, regulations and actions that may have a negative impact on its business and results of operations.

• Federal and state environmental regulation could cause the corporation to incur substantial capital expenditures and increased operating costs.

• Volatile financial markets and changes in the corporation’s debt rating could restrict the corporation’s ability to access capital and could increase borrowing costs and pension plan expenses. Disruptions, uncertainty or volatility in the financial markets can also adversely impact the results of operations, the ability of customers to finance purchases of goods and services, and the financial condition of the corporation as well as exert downward pressure on stock prices and/or limit the corporation’s ability to sustain its current common stock dividend level.

• The corporation’s defined benefit pension plan assets declined significantly during 2008 due to the volatile equity markets. The corporation is not required to make a mandatory contribution to the pension plan in 2009. However, if the market value of pension plan assets continues to decline and relief under the Pension Protection Act is no longer granted, the corporation could be required to contribute additional capital to the pension plan in 2009.

• A sustained decline in the corporation’s common stock price below book value may result in goodwill impairments that could adversely affect the corporation’s results of operations and financial position, as well as credit facility covenants.

• Any significant impairment of the corporation’s goodwill would cause a decrease in the corporation’s assets and a reduction in its net operating performance.

• Economic conditions could negatively impact the corporation’s businesses.

• If the corporation is unable to achieve the organic growth it expects, its financial performance may be adversely affected.

• The corporation’s plans to grow and diversify through acquisitions and capital projects may not be successful and could result in poor financial performance.

8

• The corporation’s plans to acquire additional businesses and grow and operate its nonelectric businesses could be limited by state law.

• The terms of some of the corporation’s contracts could expose the corporation to unforeseen costs and costs not within the corporation’s control, which may not be recoverable and could adversely affect the corporation’s results of operations and financial condition.

• The corporation is subject to risks associated with energy markets.

• Certain of the corporation’s operating companies sell products to consumers that could be subject to recall.

• Competition is a factor in all of the corporation’s businesses.

• The corporation may experience fluctuations in revenues and expenses related to its electric operations, which may cause financial results to fluctuate and could impair the corporation’s ability to make distributions to shareholders or scheduled payments on the corporation’s debt obligations.

• The corporation’s electric segment has capitalized $11.9 million in costs related to the planned construction of a second electric generating unit at its Big Stone Plant site as of March 31, 2009. If the project is abandoned for permitting or other reasons, a portion of these capitalized costs and others incurred in future periods may be subject to expense and may not be recoverable.

• Actions by the regulators of the electric segment could result in rate reductions, lower revenues and earnings or delays in recovering capital expenditures.

• Future operating results of the electric segment will be impacted by the outcome of rate rider filings in Minnesota for transmission investments.

• Future operating results of the electric segment will be impacted by the outcome of a rate case filed in North Dakota on November 1, 2008 requesting an overall increase in North Dakota rates of 5.14%. The filing included a request for an interim rate increase of 4.07%, which went into effect on January 1, 2009. Interim rates will remain in effect for all North Dakota customers until the NDPSC makes a final determination on the electric utility’s request, which is expected by August 1, 2009. If final rates are lower than interim rates, the electric utility will refund North Dakota customers the difference with interest.

• The corporation may not be able to respond effectively to deregulation initiatives in the electric industry, which could result in reduced revenues and earnings.

• The corporation’s electric generating facilities are subject to operational risks that could result in unscheduled plant outages, unanticipated operation and maintenance expenses and increased power purchase costs.

• Wholesale sales of electricity from excess generation could be affected by reductions in coal shipments to the Big Stone and Hoot Lake plants due to supply constraints or rail transportation problems beyond the corporation’s control.

• Existing or new laws or regulations addressing climate change or reductions of greenhouse gas emissions by federal or state authorities, such as mandated levels of renewable generation or mandatory reductions in carbon dioxide (CO2) emission levels, taxes on CO2 emissions or cap and trade regimes, that result in increases in electric service costs could negatively impact the corporation’s net income, financial position and operating cash flows if such costs cannot be recovered through rates granted by ratemaking authorities in the states where the electric utility provides service or through increased market prices for electricity.

• The corporation’s plastics segment is highly dependent on a limited number of vendors for PVC resin, many of which are located in the Gulf Coast regions, and a limited supply of resin. The loss of a key vendor or an interruption or delay in the supply of PVC resin could result in reduced sales or increased costs for this business. Reductions in PVC resin prices could negatively impact PVC pipe prices, profit margins on PVC pipe sales and the value of PVC pipe held in inventory.

• The corporation’s plastic pipe companies compete against a large number of other manufacturers of PVC pipe and manufacturers of alternative products. Customers may not distinguish the pipe companies’ products from those of its competitors.

9

• Competition from foreign and domestic manufacturers, the price and availability of raw materials, fluctuations in foreign currency exchange rates and general economic conditions could affect the revenues and earnings of the corporation’s manufacturing businesses.

• Changes in the rates or method of third-party reimbursements for diagnostic imaging services could result in reduced demand for those services or create downward pricing pressure, which would decrease revenues and earnings for the corporation’s health services segment.

• The corporation’s health services businesses may be unable to continue to maintain agreements with Philips Medical from which the businesses derive significant revenues from the sale and service of Philips Medical diagnostic imaging equipment.

• Technological change in the diagnostic imaging industry could reduce the demand for diagnostic imaging services and require the corporation’s health services operations to incur significant costs to upgrade their equipment.

• Actions by regulators of the corporation’s health services operations could result in monetary penalties or restrictions in the corporation’s health services operations.

• The corporation’s food ingredient processing segment operates in a highly competitive market and is dependent on adequate sources of raw materials for processing. Should the supply of these raw materials be affected by poor growing conditions, this could negatively impact the results of operations for this segment.

• The corporation’s food ingredient processing business could be adversely affected by changes in foreign currency exchange rates.

• A significant failure or an inability to properly bid or perform on projects by the corporation’s construction businesses could lead to adverse financial results.
