principles (GAAP). Management believes that adjusting for certain one-time
costs, such as debt prepayment premiums and for interest expense related to
the retired debt, and presenting results on the basis of the expected future
classification of continuing and discontinued operations will assist investors

CEO Overview

"We are pleased to have ended the year with a good quarter. 2012 was a year of
transformation. We made significant progress and our company is stronger with
enhanced financial stability, more predictable growth, and a lower risk
profile," said Otter Tail Corporation President and CEO Jim McIntyre. "In
2012, we completed the sales of DMS, our health services company, and DMI, our
wind tower manufacturer.And on February 8, 2013 we closed on the sale of
substantially all of the assets of ShoreMaster, our waterfront equipment
manufacturer. Additionally, we took steps to further strengthen our capital
structure and lower our borrowing expense by retiring our $50 million, 8.89%
Senior Unsecured Note, in connection with the sale of DMI.

"Completing the sale of DMI and garnering approximately $80 million in net
proceeds from the sale of DMI's fixed assets and monetizing its net working
capital helped fund our growth prospects in the Electric segment. We continued
to invest in key electric utility opportunities, such as the CapX2020
transmission projects currently under way, the environmental upgrades at Big
Stone Plant, and planned Midwest Independent Transmission System Operator
(MISO) transmission projects. These projects, which have already received
certain regulatory approvals, will generate significant growth for our
Electric segment over the next several years.

"We are encouraged by our 2012 performance.Consolidated operating income rose
14.1%.Our Electric segment continued its strong performance in
2012.Moreover, all of our manufacturing and infrastructure businesses, except
Foley Company, our mechanical and prime contractor on industrial projects,
showed improvement in net income. Our more focused, disciplined approach
coupled with improving consumer markets, is benefitting our financial and
operating results.

"In 2013 we will work to further improve operational and financial results
from all of our businesses. Our goal is to deliver annual growth in earnings
per share between four to seven percent over the next several years. The
growth is expected to come from the substantial increase in our regulated
utility rate base and from planned increased earnings from existing capacity
already in place in our manufacturing and infrastructure businesses. As
previously indicated, we are targeting approximately 75-85 percent of earnings
from our core electric business and 15-25 percent to come from our remaining
portfolio of companies. We believe this is sustainable over time while
maintaining strong credit quality, dependable earnings and manageable risk."

^1The corporation retired early its $50 million, 8.89% Senior Unsecured
Note due November 30, 2017 from proceeds generated in connection with
the divestiture of DMI.Generally Accepted Accounting Principles require
that in order for debt retirement premiums and related interest expense
to be reported as discontinued operations, a company must be required by
the lender to repay the related debt as a result of the disposition.
Although the corporation was not legally obligated to repay the
aforementioned note, management believes it is appropriate to associate
the 2012 debt prepayment premium and interest expense with its
discontinued operations to provide a better indication of future

Cash Flow from Operations and Liquidity

The corporation's consolidated cash flow from continuing operations for the
year ended December 31, 2012 was $169.0million compared with $93.7million
for the year ended December 31, 2011. The corporation's consolidated cash flow
from discontinued operations for the year ended December 31, 2012 was
$64.6million, compared with $10.7million for the year ended December 31,
2011. The corporation used proceeds from the sale of DMI to retire its
$50million, 8.89% Senior Unsecured Note due November 30, 2017. This early
retirement reduced the corporation's long-term debt outstanding and lowered
its cost of capital, strengthened its consolidated capital structure and will
have a positive effect on future years' earnings by lowering interest costs.

The following table presents the status of the corporation's lines of credit
as of December 31, 2012:

2012 Segment Performance Summary


Electric revenues and net income were $350.8 million and $38.3 million,
respectively, compared with revenues of $342.7million and net income of $38.9
million for 2011. Retail electric revenues increased $4.3 million as a result

  *a $2.6 million increase in transmission cost recovery revenues as a result
    of increased investment in transmission assets,
  *a $1.8 million interim rate refund in 2011 related to amounts collected
    under interim rates in Minnesota in 2010,
  *a $1.5 million increase in revenue mainly related to rate design changes
    implemented in Minnesota in October 2011 on finalization of Otter Tail
    Power Company's 2010 general rate case, and
  *a $0.9 million increase in retail revenue related to the recovery of
    increased fuel and purchased power costs,

offset by:

  *a $2.3 million decrease in revenues related to a 1.2% reduction in retail
    kilowatt-hour (kwh) sales between the periods due to an 11% reduction in
    heating-degree days resulting from significantly milder weather in the
    first half of 2012, partially offset by a 19.6% increase in cooling-degree
    days in the summer of 2012 compared with the same periods in 2011, and
  *a $0.2 million reduction in accrued conservation program cost recovery
    revenues and incentives.

Wholesale electric revenues from company-owned generation decreased $1.6
million due to a 6.7% decline in wholesale kwh sales in combination with a
4.4% decrease in the average price per wholesale kwh sold. This was related to
an 8.7% reduction in kwh generation mainly as a result of two major shutdowns
of Otter Tail Power Company's lowest-cost baseload resource, Coyote Station in
2012. The first occurred in the second quarter of 2012 for seven weeks of
scheduled maintenance, and the second occurred on November 27, 2012, when an
electrical fault caused major damage to the station's generator, which needed
to be moved offsite for repairs estimated to take 10 to 12 weeks. Lower demand
in wholesale markets and low natural gas prices for alternative generation
also contributed to the reduction in wholesale electric sales.

Net gains from energy trading activities, including net mark-to-market gains
on forward energy contracts, decreased $0.9 million mainly as a result of a
decrease in mark-to-market gains on open energy contracts, along with a
reduction in trading activity.

A $6.1 million increase in other electric operating revenues reflects:

  *a $3.6 million increase in MISO Schedule 26 transmission tariff revenues,
    driven in part by returns on, and recovery of, CapX2020 investment costs
    and operating expenses,
  *a $1.5 million increase in revenues earned under agreements for shared use
    of transmission facilities with other regional transmission providers,
  *$0.9 million in MISO Schedule 26A revenue, new in 2012, mainly related to
    investments in MISO designated Multi-Value Projects (MVPs),
  *$0.8 million in revenue earned under a contract to upgrade a distribution
    system for another regional electric service provider, and
  *a $0.7 million increase in MISO Schedule 1 transmission tariff revenues
    due to 2011 and 2012 changes in the calculation methodology used to
    determine Schedule 1 revenues,

offset by:

  *a $1.3 million reduction in revenue related to a payment received in 2011
    from a transmission cooperative to Otter Tail Energy Services Company
    (OTESCO) for access rights to construct a high voltage transmission line
    through a wind farm site where OTESCO owned development rights, and for
    assistance in obtaining easements from landowners.

Fuel costs decreased $2.7 million as a result of a 9.0% decrease in kwhs
generated from Otter Tail Power Company's steam-powered and combustion turbine
generators, partially offset by a 5.5% increase in the cost of fuel per kwh
generated. The decrease in kwh generation was due to the two major maintenance
shutdowns of Coyote Station in 2012. The cost of purchased power for retail
sales increased $5.7 million as a result of a 28.2% increase in kwhs purchased
for system use, partially offset by an 11.7% decrease in the cost per kwh
purchased. The increase in kwh purchases was driven by the need to buy
replacement power after Coyote Station went off-line in November 2012.

Electric operating and maintenance expenses increased $5.7 million due to the

  *a $3.4 million increase in MISO transmission service charges, mainly MISO
    Schedule 26 charges related to increased investment in transmission
    facilities by MISO member companies,
  *a $2.2 million increase in labor and benefit expenses mainly due to
    increases in pension and retiree health benefit costs resulting from a
    reduction in the discount rate applied to projected benefit obligations,
  *a $1.1 million increase in maintenance expenses at Coyote Station related
    to its second quarter 2012 seven-week scheduled major maintenance
  *a $0.5 million increase in property tax expense related to higher taxes on
    electric distribution property and increased investments in transmission
  *a $0.4 million increase in wind farm maintenance service costs, and
  *a $0.3 million increase in maintenance costs at Big Stone Plant,

offset by:

  *a $1.7 million reduction in material and supply costs related to costs
    incurred in conjunction with a major overhaul of Big Stone Plant in the
    fourth quarter of 2011, and
  *a $0.4 million reduction in incurred conservation program costs,
    commensurate with a reduction in accrued revenues related to the future
    recovery of those costs.

Other Income in the Electric segment increased $0.5 million as a result of:

  *a $0.3 million increase in allowances for equity funds used during
    construction (AFUDC), mainly related to costs incurred in conjunction with
    planning and construction of a new air quality control system (AQCS) at
    Big Stone Plant, and
  *a $0.2 million increase in investment income.


ShoreMaster's results have been reclassified to discontinued operations, as it
meets the accounting criteria for assets held for sale at the end of 2012 and
are no longer included in the Manufacturing segment.

Manufacturing revenues and net income were $209.0million and $10.7 million,
respectively, compared with $189.5 million and $8.2 million for 2011.

  *At BTD, revenues increased $17.7 million and net income increased $1.4
    million as a result of higher sales volume due to improved customer demand
    for products and services.
  *At T.O. Plastics, revenues increased by $1.8 million and net income
    increased $1.1 million as a result of increased sales of industrial and
    medical products. Productivity improvements and more selective bidding
    practices also contributed to the increase in net income at T.O. Plastics.


Construction revenues and net losses were $149.1 million and $7.7 million,
respectively, compared with $184.7million and $2.2 million for 2011.

  oFoley Company revenues decreased $48.3million and its net losses
    increased $7.7 million due to a decrease in work volume and the effect of
    cost overruns on estimated revenues recognized under
    percentage-of-completion accounting. Estimated costs on certain large
    projects in excess of previous period estimates resulted in pretax charges
    of $14.9 million in 2012 compared with $7.0 million in 2011. Substantially
    all of these projects had been completed or were in the final stages of
    completion as of December 31, 2012.
  oAevenia's revenues and net income increased $12.7million and $2.2
    million, respectively, mainly as a result of an increase in electrical
    transmission, distribution and substation work in the oil patch region of
    western North Dakota and improved performance on construction projects.


Plastics revenues and net income were $150.5 million and $14.1million,
respectively, compared with revenues of $123.7 million and net income of $5.8
million for 2011. The increase in revenues and net income was due to a 17.0%
increase in pounds of pipe sold combined with a 4.1% increase in the price per
pound of pipe sold, while the cost per pound of pipe sold decreased by 6.6%
between the years. The decrease in the cost per pound of pipe sold was due to
lower prices of resin between the years and increased productivity as fixed
production costs were spread over a larger volume of pipe produced over longer
production runs with less downtime.


Corporate expenses, net-of-tax, increased $0.7 million between the years. The
increase in corporate expenses includes the $7.9 million after tax charge for
the early retirement of long-term debt offset by $7.2 million in net-of-tax
reductions in operating expenses, including reductions in compensation and
benefit costs and less interest expense due to the retirement of the $50
million Senior Unsecured Note on July 13, 2012 and a $28.5 million reduction
in the daily average balance of short-term debt outstanding between the years
under the Otter Tail Corporation line of credit.

Discontinued Operations

On February 8, 2013 the corporation closed on the sale of substantially all
the assets of ShoreMaster for approximately $13.0 million in cash plus a
future working capital true up to be finalized within 180 days of closing. The
corporation recorded a $4.6 million net-of-tax impairment of ShoreMaster's
assets in December 2012 based on the market value of ShoreMaster's assets. On
November 30, 2012 the corporation completed the sale of DMI's assets for total
proceeds, net of commissions and selling costs, of $18.1 million. On February
29, 2012 the corporation completed the sale of DMS for $30.0 million in cash.
On January 18, 2012, the corporation sold the assets of Aviva Sports, Inc.
(Aviva), a wholly owned subsidiary of ShoreMaster that sold various
recreational products, for $0.3 million in cash.

On December29, 2011 the corporation completed the sale of E.W. Wylie
Corporation (Wylie), its trucking business, for approximately $25.0million in
cash. The proceeds from the sale of Wylie were used for general corporate
purposes. On May 6, 2011 the corporation completed the sale of Idaho Pacific
Holdings, Inc. (IPH), its food ingredient processing business, for
approximately $86.0million in cash. The proceeds from the sale, net of $3.0
million deposited in an escrow account, were used to pay down borrowings under
the corporation's then existing credit agreement.

The financial position, results of operations and cash flows of ShoreMaster,
DMI, DMS, Aviva, Wylie and IPH are reported as discontinued operations in the
corporation's consolidated financial statements provided at the end of this
report. Following are summary presentations of the results of discontinued
operations for the years ended December 31, 2012 and 2011:

Realigning the corporation's portfolio of businesses and refocusing its
capital investment are important to reducing its risk profile, as well as
better supporting its credit metrics, which enhances its ability to support
the dividend and capitalize on available growth opportunities. The corporation
may continue to pursue other opportunities for strategic realignment.

Fourth Quarter 2012 Consolidated Results

Operating revenues were $212.6million compared with $207.3 million for the
same quarter a year ago. Operating income was $24.2million compared with
$12.6million for the fourth quarter of 2011.

Net income from continuing operations was $17.1 million compared with $6.0
million in the fourth quarter of 2011. Fourth quarter 2012 net income from
continuing operations includes increases in net income in all of the
corporation's operating segments.

Net income from continuing and discontinued operations was $3.0 million
compared with a net loss of $44.1million in the fourth quarter of 2011. The
fourth quarter 2011 net loss from continuing and discontinued operations
mainly reflects a net loss from discontinued operations of $50.1 million,
which included:

  oa $39.1 million net-of-tax asset impairment charge at DMS resulting from
    the write down of DMS to its fair value based on DMS's indicated sales
    price, and
  oa $3.8 million after-tax loss on the sale of Wylie.

Diluted earnings per share from continuing operations were $0.47 compared with
$0.16 for the fourth quarter of 2011. Diluted earnings (losses) per share from
continuing and discontinued operations were $0.08 compared with ($1.23) for
the fourth quarter of 2011.

2013 Business Outlook

The corporation anticipates 2013 diluted earnings per share to be in the range
of $1.30 to $1.55. This guidance reflects the current mix of businesses owned
by the corporation as it starts out 2013. It considers the cyclical nature of
some of the corporation's businesses and reflects challenges presented by
current economic conditions, as well as the corporation's plans and strategies
for improving future operating results. The corporation's current consolidated
capital expenditures expectation for 2013 is in the range of $200 million to
$210million. This compares with $116 million of capital expenditures in 2012.
The major project contributing to the increase in planned expenditures is the
new AQCS for Big Stone Plant to meet requirements of the federal Clean Air Act
and regional haze regulations. The corporation plans to invest in generation
and transmission projects for the Electric segment that are expected to
positively impact the corporation's earnings and returns on capital. In
addition to the AQCS project, current Electric segment projects include
investment in three MISO-determined MVP transmission projects that will serve
the nine-state MISO region, of which one is a CapX2020 project already under
way, and investment with other utilities in one other remaining CapX2020
transmission project also under way.

Segment components of the corporation's 2013 earnings per share guidance range
are as follows:

Contributing to the earnings guidance for 2013 are the following items:

  *The corporation expects net income to increase slightly in its Electric
    segment in 2013 compared with 2012. This is based on rider recovery
    increases and an increase in AFUDC related to larger construction
    expenditures, offset by lower conservation improvement program incentives
    and increases in operating and maintenance expenses due to higher benefit
    costs. Otter Tail Power Company's pension benefit costs for the
    corporation's noncontributory funded pension plan are expected to increase
    by $2.7million in 2013, reflecting a change in the assumed rate of return
    on pension plan assets from 8.0% in 2012 to 7.75% in 2013 and a decrease
    in the estimated discount rate used to determine annual benefit cost
    accruals from 5.15% in 2012 to 4.50% in 2013.
  *The corporation expects earnings from its Manufacturing segment to improve
    in 2013 due to the following factors:

    *Increased order volume and continuing improvement in economic conditions
      in the industries BTD serves,
    *A slight increase in earnings from T.O. Plastics, and
    *Backlog for the manufacturing companies of approximately $124million
      for 2013 compared with $115million one year ago.

  *The corporation expects higher net income from its Construction segment in
    2013 as it has implemented improved cost control processes in construction
    management and selectively bid on projects with the potential for higher
    margins. 2012 was negatively impacted by the results on certain large
    projects at Foley. These projects are now substantially completed and
    Foley's internal bidding and estimating project review procedures have
    been improved such that the corporation does not expect to see similar
    losses in 2013. Backlog in place for the construction businesses is $151
    million for 2013 compared with $106 million one year ago.
  *The Plastics segment experienced its second best earnings year in its
    history in 2012 due in part to certain market and weather related events
    that are not expected to recur in 2013. Accordingly, the corporation
    expects 2013 net earnings for Plastics to be lower based on the market and
    weather conditions currently being experienced.
  *Corporate general and administrative costs are expected to remain
    relatively flat between the years.

The sales of DMI and ShoreMaster were strategic decisions by management to
monetize assets and divest of companies that do not fit with the corporation's
current operating plans. The divestitures free up liquidity going forward for
upcoming Electric segment capital investments. The corporation will continue
to review its portfolio to see where additional opportunities exist to improve
its risk profile, improve credit metrics and generate additional sources of
cash to support the future capital expenditure plans of its Electric segment.
This will result in a larger percentage of the corporation's earnings coming
from Otter Tail Power Company, its most stable and relatively predictable
business, and is consistent with the strategy to grow this business given its
current investment opportunities.

The following table shows the corporation's 2012 actual and 2013 through 2017
anticipated capital expenditures and electric utility average rate base:

Execution on the currently anticipated electric utility capital expenditure
plan is expected to grow rate base and be a key driver in increasing utility
earnings over the 2013 through 2017 timeframe. The corporation intends to
maintain its equity-to-total capitalization ratio near its present level of
52% in its Electric segment and will seek to earn its authorized overall
return on equity of approximately 10.5% in the utility's regulatory

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

The information in this release includes certain forward-looking information,
including 2013 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:

  oFederal and state environmental regulation could require the corporation
    to incur substantial capital expenditures and increased operating costs.
  oVolatile financial markets and changes in the corporation's debt ratings
    could restrict its ability to access capital and could increase borrowing
    costs and pension plan and postretirement health care expenses.
  oThe corporation relies on access to both short- and long-term capital
    markets as a source of liquidity for capital requirements not satisfied by
    cash flows from operations. If the corporation is not able to access
    capital at competitive rates, its ability to implement its business plans
    may be adversely affected.
  oDisruptions, uncertainty or volatility in the financial markets can also
    adversely impact the corporation's results of operations, the ability of
    its customers to finance purchases of goods and services, and its
    financial condition, as well as exert downward pressure on stock prices
    and/or limit its ability to sustain its current common stock dividend
  oThe corporation made a $10.0 million discretionary contribution to its
    defined benefit pension plan in January 2013. The corporation could be
    required to contribute additional capital to the pension plan in the
    future if the market value of pension plan assets significantly declines,
    plan assets do not earn in line with the corporation's long-term rate of
    return assumptions or relief under the Pension Protection Act is no longer
  oAny significant impairment of the corporation's goodwill would cause a
    decrease in its asset values and a reduction in its net operating income.
  oA sustained decline in the corporation's common stock price below book
    value or declines in projected operating cash flows at any of its
    operating companies may result in goodwill impairments that could
    adversely affect its results of operations and financial position, as well
    as financing agreement covenants.
  oThe corporation currently has $7.3 million of goodwill and a $1.1 million
    indefinite-lived trade name recorded on its consolidated balance sheet
    related to the acquisition of Foley Company in 2003. Foley Company
    generated a large operating loss in 2012 due to significant cost overruns
    on certain construction projects. If operating margins do not meet the
    corporation's projections, the reductions in anticipated cash flows from
    Foley Company may indicate that its fair value is less than its book
    value, resulting in an impairment of some or all of the goodwill and
    indefinite-lived trade name associated with Foley along with a
    corresponding charge against earnings.
  oThe inability of the corporation's subsidiaries to provide sufficient
    earnings and cash flows to allow the corporation to meet its financial
    obligations and debt covenants and pay dividends to its shareholders could
    have an adverse effect on the corporation.
  oEconomic conditions could negatively impact the corporation's businesses.
  oIf the corporation is unable to achieve the organic growth it expects, its
    financial performance may be adversely affected.
  oThe corporation's plans to grow and realign its business mix through
    capital projects, acquisitions and dispositions may not be successful,
    which could result in poor financial performance.
  oThe corporation may, from time to time, sell assets to provide capital to
    fund investments in its electric utility business or for other corporate
    purposes, which could result in the recognition of a loss on the sale of
    any assets sold and other potential liabilities. The sale of any of the
    corporation's businesses could expose the corporation to additional risks
    associated with indemnification obligations under the applicable sales
    agreements and any related disputes.
  oThe corporation's plans to grow and operate businesses outside of its
    electric utility, while also owning a regulated utility, could be limited
    by state law.
  oThe corporation's subsidiaries enter into construction contracts which
    could expose them to unforeseen costs and costs not within their control,
    which may not be recoverable and could adversely affect the corporation's
    results of operations and financial condition.
  oSignificant warranty claims and remediation costs in excess of amounts
    normally reserved for such items could adversely affect the corporation's
    results of operations and financial condition.
  oThe corporation is subject to risks associated with energy markets.
  oThe corporation is subject to risks and uncertainties related to the
    timing and recovery of deferred tax assets which could have a negative
    impact on the corporation's net income in future periods.
  oA significant failure or an inability to properly bid or perform on
    projects or contracts by the corporation's construction businesses could
    lead to adverse financial results and could lead to the possibility of
    delay or liquidated damages.
  oThe corporation relies on its information systems to conduct its business,
    and failure to protect these systems against security breaches could
    adversely affect its business and results of operations. Additionally, if
    these systems fail or become unavailable for any significant period of
    time, the corporation's business could be harmed.
  oThe corporation may experience fluctuations in revenues and expenses
    related to its electric operations, which may cause its financial results
    to fluctuate and could impair its ability to make distributions to its
    shareholders or scheduled payments on its debt obligations, or to meet
    covenants under its borrowing agreements.
  oActions by the regulators of the corporation's electric operations could
    result in rate reductions, lower revenues and earnings or delays in
    recovering capital expenditures.
  oOtter Tail Power Company'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.
  oChanges to regulation of generating plant emissions, including but not
    limited to carbon dioxide (CO[2]) emissions, could affect Otter Tail Power
    Company's operating costs and the costs of supplying electricity to its
  oCompetition from foreign and domestic manufacturers, the price and
    availability of raw materials and general economic conditions could affect
    the revenues and earnings of our manufacturing businesses.
  oThe 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 segment.
  oThe 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.
  oReductions in PVC resin prices can negatively impact PVC pipe prices,
    profit margins on PVC pipe sales and the value of PVC pipe held in
