<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Powell Industries, Inc. (we, us, our, Powell or the Company) was incorporated in the state of
Delaware in 2004 as a successor to a Nevada company incorporated in 1968. The Nevada corporation
was the successor to a company founded by William E. Powell in 1947, which merged into the Company
in 1977. Our major subsidiaries, all of which are wholly-owned, include: Powell Electrical Systems,
Inc.; Transdyn, Inc.; Powell Industries International, Inc.; Switchgear &#038; Instrumentation Limited
(S&#038;I) and Powell Canada Inc.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We develop, design, manufacture and service custom engineered-to-order equipment and systems for
the management and control of electrical energy and other critical processes. Headquartered in
Houston, Texas, we serve the transportation, environmental, energy, industrial and utility
industries.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In December&nbsp;2009, we acquired the business and certain assets of PowerComm Inc. and its
subsidiaries (referred to herein as Powell Canada) for $23.4&nbsp;million, not including expenses.
Powell Canada is headquartered in Edmonton, Alberta, Canada, and provides electrical and
maintenance services. Powell Canada is also a manufacturer of switchgear and related products,
primarily serving the oil and gas industry in western Canada. The operating results of Powell
Canada are included in our Electrical Power Products business segment from the acquisition date.
For further information on the Powell Canada acquisition, see Note C.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">These unaudited condensed consolidated financial statements include the accounts of Powell and its
wholly-owned subsidiaries. All significant intercompany accounts and transactions have been
eliminated in consolidation.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">These unaudited condensed consolidated financial statements have been prepared pursuant to the
rules of the Securities and Exchange Commission (SEC). Certain information and footnote
disclosures, normally included in annual financial statements prepared in accordance with
accounting principles generally accepted in the United States (U.S. GAAP), have been condensed or
omitted pursuant to those rules and regulations. We believe that the disclosures made are adequate
to make the information presented not misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to fairly state the financial position,
results of operations and cash flows with respect to the interim consolidated financial statements
have been included. The results of operations for the interim periods are not necessarily
indicative of the results for the entire fiscal year. The year-end balance sheet data was derived
from audited financial statements, but does not include all disclosures required by U.S. GAAP.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">These unaudited condensed consolidated financial statements should be read in conjunction with the
audited consolidated financial statements and notes thereto of Powell and its subsidiaries included
in Powell&#146;s Annual Report on Form 10-K for the year ended September&nbsp;30, 2010, which was filed with
the SEC on December&nbsp;8, 2010.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The preparation of financial statements in conformity with U.S. GAAP requires management to make
estimates and assumptions that affect the amounts reported in the condensed consolidated financial
statements and accompanying footnotes. The most significant estimates used in our financial
statements affect revenue and cost recognition for construction contracts, the allowance for
doubtful accounts, provision for excess and obsolete inventory, goodwill and other intangible
assets, self-insurance, warranty accruals, income taxes and estimates related to acquisition
valuations. The amounts recorded for insurance claims, warranties, legal, income taxes and other
contingent liabilities require judgments regarding the amount of expenses that will ultimately be
incurred. We base our estimates

surrounding these contingent liabilities, in evaluating the amount of liability that should be
recorded. Estimates may change as new events occur, additional information becomes available or
operating environments change. Actual results may differ from our estimates.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>New Accounting Standards</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In December&nbsp;2008, the Financial Accounting Standards Board (FASB)&nbsp;issued accounting guidance on
employers&#146; disclosures about postretirement benefit plan assets. The disclosures about plan assets
required by this guidance shall be provided for fiscal years ending after December&nbsp;15, 2009, and
was adopted by us in the first quarter of fiscal year 2011. Adoption of this guidance did not have
a material impact on our consolidated financial statements.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In April&nbsp;2009, the FASB issued accounting guidance regarding the accounting for assets acquired and
liabilities assumed in a business combination due to contingencies. This guidance clarifies the
initial and subsequent recognition, subsequent accounting and disclosure of assets and liabilities
arising from contingencies in a business combination. This guidance requires that assets acquired
and liabilities assumed in a business combination that arise from contingencies be recognized at
fair value, if the acquisition-date fair value can be reasonably estimated. If the
acquisition-date fair value of an asset or liability cannot be reasonably estimated, the asset or
liability would be measured at the amount that would be recognized using the accounting guidance
related to accounting for contingencies or the guidance for reasonably estimating losses. This
accounting guidance became effective for us on October&nbsp;1, 2010. The adoption of this guidance did
not have an impact on our consolidated financial statements.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In January&nbsp;2010, the FASB issued updated guidance to amend the disclosure requirements related to
recurring and nonrecurring fair value measurements. This update requires new disclosures about
significant transfers of assets and liabilities between Level 1 and Level 2 of the fair value
hierarchy (including the reasons for these transfers) and the reasons for any transfers in or out
of Level 3. This update also requires a reconciliation of recurring Level 3 measurements about
purchases, sales, issuances and settlements on a gross basis. In addition to these new disclosure
requirements, this update clarifies certain existing disclosure requirements. For example, this
update clarifies that reporting entities are required to provide fair value measurement disclosures
for each class of assets and liabilities, rather than each major category of assets or liabilities.
This update also clarifies the requirement for entities to disclose information about both the
valuation techniques and inputs used in estimating Level 2 and Level 3 fair value measurements.
This update became effective for us with the interim and annual reporting period beginning after
December&nbsp;15, 2009, our fiscal year 2011, except for the requirement to provide the Level 3 activity
of purchases, sales, issuances and settlements on a gross basis, which will become effective for us
with the interim and annual reporting period beginning after December&nbsp;15, 2010, our fiscal year
2012. We will not be required to provide the amended disclosures for any previous periods
presented for comparative purposes. Other than requiring additional disclosures, adoption of this
update for the provisions currently in effect for us did not have a material impact on our
consolidated financial statements.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In April&nbsp;2010, the FASB issued accounting guidance for the milestone method of revenue recognition.
This guidance allows entities to make a policy election to use the milestone method of revenue
recognition and provides guidance on defining a milestone and the criteria that should be met for
applying the milestone method. The scope of this guidance is limited to transactions involving
milestones relating to research and development. The guidance includes enhanced disclosure
requirements about each arrangement, individual milestones and related contingent consideration,
information about substantive milestones and factors considered in the determination. This
guidance is effective prospectively to milestones achieved in fiscal years, and interim periods
within those years, beginning after June&nbsp;15, 2010. Early application and retrospective application
are permitted. We have evaluated this new guidance and have determined that it will not currently
have a significant impact on the determination or reporting of our financial results.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Subsequent Events</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We evaluated subsequent events through the time of filing this Quarterly Report on Form&nbsp;10-Q. No
significant events occurred subsequent to the balance sheet or prior to the filing of this report
that would have a material impact on our consolidated financial statements or results of
operations.

</DIV>

<!-- xbrl,body -->
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We measure certain financial assets and liabilities at fair value. Fair value is defined as an
&#147;exit price&#148; which represents the amount that would be received to sell an asset or paid to
transfer a liability in an orderly transaction between market participants as of the measurement
date. As such, fair value is a market-based measurement that should be determined based on
assumptions that market participants would use in valuing an asset or liability. The accounting
guidance requires the use of valuation techniques to measure

As a basis for considering such assumptions and inputs, a fair value hierarchy has been established
which identifies and prioritizes three levels of inputs to be used in measuring fair value.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The three levels of the fair value hierarchy are as follows:

directly or indirectly, including: quoted prices for similar assets and liabilities in active
markets; quoted prices for identical or similar assets and liabilities in markets that are not
active or other inputs that are observable or can be corroborated by observable market data.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Level 3 &#151; Unobservable inputs that are supported by little or no market data and require the
reporting entity to develop its own assumptions.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cash equivalents, primarily funds held in money market instruments, are reported at their current
carrying value which approximates fair value due to the short-term nature of these instruments and
are included in cash and cash equivalents in our Condensed Consolidated Balance Sheets.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Foreign currency forward contracts are valued using an income approach which consists of a
discounted cash flow model that takes into account the present value of future cash flows under the
terms of the contracts using observable market spot and forward rates as of our reporting date, and
are included in Level 2 inputs in the above table. We use these derivative instruments to mitigate
non-functional currency transaction exposure on certain contracts with customers and vendors. We
mitigate derivative credit risk by transacting with highly rated counterparties. We have evaluated
the credit and non-performance risks associated with our derivative counterparties and believe them
to be insignificant at March&nbsp;31, 2011. All contracts are recorded at fair value and
marked-to-market at the end of each reporting period, with unrealized gains and losses being
included in accumulated other comprehensive income on our Condensed Consolidated Balance Sheets for
that period. See Note I for further discussion regarding our derivative instruments.

</DIV>

<!-- xbrl,body -->
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On December&nbsp;15, 2009, we acquired the business and certain assets of PowerComm Inc. and its
subsidiaries, Redhill Systems, Ltd., Nextron Corporation, PCG Technical Services Inc. and Concorde
Metal Manufacturing Ltd (the business of which is referred to herein as Powell Canada). Powell
Canada is headquartered in Edmonton, Alberta, Canada, and provides electrical and maintenance
services in western Canada. Powell Canada is also a manufacturer of switchgear and related
products, primarily serving the oil and gas industry in western Canada. This acquisition supports
our strategy to expand our geographic presence into Canada, as well as increasing our service and
maintenance capabilities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We paid $23.4&nbsp;million, plus expenses of approximately $2.4&nbsp;million, for the acquisition from our
existing cash and cash equivalents and assumed $15.1&nbsp;million of existing bank debt. See the table
below for assets acquired and liabilities assumed. In December&nbsp;2009, approximately $2.4&nbsp;million of
the $23.4&nbsp;million purchase price was placed into an escrow account related to the purchase of
PowerComm&#146;s 50% interest in the operations of a joint venture in Kazakhstan. This transaction
closed in April&nbsp;2010 and the escrow was released. The finalization of the net asset adjustment
related to the Kazakhstan transaction and the calculation of the management fee agreement related
to the operating results of the Kazakhstan joint venture from December&nbsp;16, 2009, through March&nbsp;31,
2010, as defined in the acquisition agreement, resulted in a refund to the Company of approximately
$472,000. This refund was received by the Company subsequent to September&nbsp;30, 2010, and reduced
the corresponding receivable.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Intangible assets recorded are approximately $9.0&nbsp;million and are being amortized over an initial
weighted average life of approximately 8.4&nbsp;years. Goodwill was initially recorded at approximately
$7.2&nbsp;million and was not amortized. Goodwill represented the excess purchase price over the
estimated fair value allocated to the net assets acquired. During fiscal 2010, our impairment
analysis indicated that the goodwill related to the acquisition of Powell Canada was completely

In the fourth quarter of fiscal year 2010, the Company made a strategic decision
to exit the 50%
owned joint venture in Kazakhstan. We did not record our share of revenue and expense or assets and liabilities as financial
information was not available, and based on the fact that this information was not material to the
consolidated financial position or results of operations of the Company.
We received approximately $1.2&nbsp;million in the second quarter of
fiscal 2011 resulting from the sale of our 50% investment in a joint venture in Kazakhstan, which
is recorded in other income in our Condensed Consolidated Statements of Operations.

$1.5&nbsp;million at March&nbsp;31, 2011.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>US and UK Revolvers</I>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In December&nbsp;2007 and 2008, we amended our existing credit agreement (Amended Credit Agreement) with
a major domestic bank and certain other financial institutions. These amendments to our credit
facility were made to expand our US borrowing capacity to provide additional working capital
support for the Company. The Amended Credit Agreement provides for a 1) $58.5&nbsp;million revolving
credit facility (US Revolver); 2) &#163;4.0&nbsp;million (pound sterling) (approximately $6.4&nbsp;million)
revolving credit facility (UK Revolver) and 3) &#163;6.0&nbsp;million (approximately $9.6&nbsp;million) single
advance term loan (UK Term Loan). The UK Term Loan was repaid in September&nbsp;2009 and may not be
reborrowed. Expenses associated with the issuance of the original credit agreement are classified
as deferred loan costs, totaled $576,000 and are being amortized as a non-cash charge to interest
expense. Obligations are collateralized by the stock of certain of our subsidiaries.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The interest rate for amounts outstanding under the Amended Credit Agreement for the US Revolver is
a floating rate based upon the higher of the Federal Funds Rate plus 0.5%, or the bank&#146;s prime
rate. Once the applicable rate is determined, a margin ranging from negative 0.5% to 0.5%, as
determined by our consolidated leverage ratio, is added to the applicable rate. The floating
interest rate for amounts outstanding under the Amended Credit Agreement for the UK Revolver is a
floating rate based upon the LIBOR plus a margin which can range from 1.25% to 2.25%, as determined
by our consolidated leverage ratio as defined within the Amended Credit Agreement.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The US Revolver and UK Revolver provide for the issuance of letters of credit which reduce the
amounts available under the respective revolvers. The amount available under the US Revolver was
reduced by approximately $11.6&nbsp;million for our outstanding letters of credit at March&nbsp;31, 2011.
There were no letters of credit outstanding under the UK Revolver.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">There were no borrowings under the US Revolver or the UK Revolver as of March&nbsp;31, 2011. Amounts
available under the US Revolver and the UK Revolver were approximately $46.9&nbsp;million and $6.4
million, respectively, at March&nbsp;31, 2011. The US Revolver and the UK Revolver expire on December
31, 2012.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Canadian Revolver</I>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On December&nbsp;15, 2009, we entered into a credit agreement with a major international bank (the
Canadian Facility) to finance the $15.1&nbsp;million debt assumed in the acquisition of Powell Canada,
and to provide additional working capital support for our operations in Canada. The Canadian
Facility provides for a $20&nbsp;million CAD (approximately $20.6&nbsp;million) revolving credit facility
(the Canadian Revolver), subject to certain limitations including a limitation on borrowings based
upon certain financial ratios, as defined in the credit agreement. Expenses associated with the
Canadian Facility were approximately $0.1&nbsp;million and are classified as deferred loan costs in
other assets and are being amortized as a non-cash charge to interest expense over two years.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Canadian Revolver provides for the issuance of letters of credit which reduce the amounts which
may be borrowed under the Canadian Revolver. As of March&nbsp;31, 2011, there were no letters of credit
outstanding under the Canadian Revolver.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">There were no borrowings outstanding under the Canadian Revolver, and approximately $20.6&nbsp;million
was available at March&nbsp;31, 2011. The amount available under the Canadian Revolver was reduced to
approximately $15.5&nbsp;million based upon the available borrowing base as defined in the Canadian
Facility credit agreement. The Canadian Facility expires on February&nbsp;29, 2012. The interest rate
for amounts outstanding under the Canadian Revolver is a floating interest rate based upon either
the Canadian Prime Rate, or the lender&#146;s US Bank Rate. Once the applicable rate is determined, a
margin of 0.3755% to 1.125%, as determined by our consolidated leverage ratio, is added to the
applicable rate.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The principal financial covenants are consistent with those in our US Revolver facility. As
discussed above, the borrowings under the Canadian Revolver are subject to a borrowing base
limitation. The Canadian Facility contains a &#147;material adverse effect&#148; clause. A material adverse
effect is defined as a material change in the operations of Powell or Powell Canada in relation to
our financial condition, property, business operations, expected net cash flows, liabilities or
capitalization.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Canadian Facility is secured by the assets of our Canadian operations and provides for
customary events of default and carries cross-default provisions with our existing debt agreements.
If an event of default (as defined in the Canadian Facility credit agreement) occurs and is
continuing, on the terms and subject to the conditions set forth in the Canadian Facility credit
agreement, amounts outstanding under the Canadian Facility may be accelerated and may become
immediately due and payable. As of March&nbsp;31, 2011, we were in compliance with all of the financial
covenants of the Canadian Facility credit agreement.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Industrial Development Revenue Bonds</I>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We borrowed $8.0&nbsp;million in October&nbsp;2001 through a loan agreement funded with proceeds from tax-exempt industrial development revenue
bonds (Bonds). These Bonds were issued by the Illinois Development Finance Authority and were used for the completion of our Northlake,
Illinois facility. Pursuant to the Bond issuance, a reimbursement agreement between us and a major domestic bank required an issuance by the
bank of an irrevocable direct-pay letter of credit (Bond LC) to the Bonds&#146; trustee to guarantee payment of the Bonds&#146; principal and interest when
due. The Bond LC is subject to both early termination and extension provisions customary to such agreements, as well as various covenants, for
which we are in compliance at March&nbsp;31, 2011. While the Bonds mature in 2021, the reimbursement agreement requires annual redemptions of
$400,000 that commenced on October&nbsp;25, 2002. A sinking fund is used for the redemption of the Bonds. At March&nbsp;31, 2011, the balance in the
restricted sinking fund was approximately $234,000 and was recorded in cash and cash equivalents. The Bonds bear interest at a floating rate
determined weekly by the Bonds&#146; remarketing agent, which was the underwriter for the Bonds and is an affiliate of the bank. This interest rate
was 0.46% per year on March&nbsp;31, 2011.

</DIV>

<!-- xbrl,body -->
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We operate in various countries and have operations in the United Kingdom and Canada. These
international operations expose us to market risk associated with foreign currency exchange rate
fluctuations. We have entered into certain forward contracts to hedge the risk of certain foreign
currency rate fluctuations. To the extent we choose to manage volatility associated with the net
exposures, we enter into various financial transactions which we account for using the applicable
accounting guidance for derivative instruments and hedging activities. Our objective is to hedge
the variability in forecasted cash flow due to the foreign currency risk associated with certain
long-term sales. As of March&nbsp;31, 2011, we held only derivatives that were designated as cash flow
hedges related to the U.S. Dollar/British Pound Sterling exchange rate and the Euro/British Pound
Sterling exchange rate.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">All derivatives are recognized on the Condensed Consolidated Balance Sheets at their fair value and
classified based on the instrument&#146;s maturity date. The total notional amount of outstanding
derivatives as of March&nbsp;31, 2011 was approximately $1.0&nbsp;million.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The purpose of our foreign currency hedging activities is to protect us from the risk that the
eventual cash flows resulting from transactions that are denominated in currencies other than the
U.S. Dollar will be adversely affected by changes in exchange rates. We are currently hedging our
exposure to the reduction in value of forecasted foreign currency cash flows through foreign
currency forward agreements through September&nbsp;30, 2011, for transactions denominated in the British
Pound Sterling.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">All changes in the fair value of outstanding cash flow hedge derivatives, except the ineffective
portion, are recorded in accumulated other comprehensive income, until net income is affected by
the variability of cash flows of the hedged transaction, or until it is probable that the
forecasted transaction will not occur. In most cases, amounts recorded in accumulated other
comprehensive income will be released to net income some time after the maturity of the related
derivative. The Condensed Consolidated Statements of Operations&#146; classification of effective hedge
results is the same as that of the underlying exposure. Results of hedges of revenue and product
costs are recorded in revenue and costs of sales, respectively, when the underlying hedged
transaction affects net income. Results of hedges of selling and administrative expense, if any,
are recorded together with those costs when the related expense is recorded. In addition, any
ineffective portion of the changes in the fair value of the derivatives designated as cash flow
hedges are reported in the Condensed Consolidated Statements of Operations as the changes occur.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As of March&nbsp;31, 2011, approximately $16,000 of deferred net losses (net of tax) on outstanding
derivatives recorded in accumulated other comprehensive income are expected to be reclassified to
net income during the next twelve months as a result of underlying hedged transactions being
recorded in net income. Actual amounts ultimately reclassified to net income are dependent on the
exchange rates in effect when the derivative contracts that are currently outstanding mature. As of
March&nbsp;31, 2011, the maximum term over which we are hedging exposure to the variability of cash
flows for our forecasted and recorded transactions is six months. For

hedging instruments. The ability of financial counterparties to perform under financial instruments
has become less certain. We attempt to take into account the financial viability of counterparties
in both valuing the instruments and determining their effectiveness as hedging instruments. If a
counterparty was unable to perform, our ability to qualify for hedging certain transactions would
be compromised and the realizable value of the financial instruments would be uncertain. As a
result, our results of operations and cash flows would be impacted.

officers and key employees. An additional 5,000 RSUs were granted in October&nbsp;2010, with a fair
value of $32.12. The RSUs vest over a three-year period from their date of issuance. The fair
value of the RSUs was based on the closing price of our common stock as reported on the NASDAQ
Global Market (NASDAQ)&nbsp;on the grant dates. The actual amount of the RSUs earned will be based on
the cumulative earnings per share as reported relative to established goals for the three-year
performance cycle which began October 1 of the year granted, and ranges from 0% to 150% of the
target RSUs granted. At March&nbsp;31, 2011, there were approximately 105,000 RSUs outstanding. The RSUs

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are including the following discussion to inform our existing and potential shareholders
generally of some of the risks and uncertainties that can affect our Company and to take advantage
of the &#147;safe harbor&#148; protection for forward-looking statements that applicable federal securities
law affords.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">From time to time, our management or persons acting on our behalf make forward-looking statements
to inform existing and potential shareholders about our Company. These statements may include
projections and estimates concerning the timing and success of specific projects and our future
backlog, revenues, income and capital spending. Forward-looking statements are generally
accompanied by words such as &#147;estimate,&#148; &#147;project,&#148; &#147;predict,&#148; &#147;believe,&#148; &#147;expect,&#148; &#147; anticipate,&#148;
&#147;plan,&#148; &#147;goal&#148; or other words that convey the uncertainty of future events or outcomes. In
addition, sometimes we will specifically describe a statement as being a forward-looking statement
and refer to this cautionary statement.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In addition, various statements in this Quarterly Report on Form 10-Q, including those that express
a belief, expectation or intention, as well as those that are not statements of historical fact,
are forward-looking statements. These forward-looking statements speak only as of the date of this
report; we disclaim any obligation to update these statements unless required by securities law,
and we caution you not to rely on them unduly. We have based these forward-looking statements on
our current expectations and assumptions about future events. While our management considers these
expectations and assumptions to be reasonable, they are inherently subject to significant business,
economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which
are difficult to predict and many of which are beyond our control. These risks, contingencies and
uncertainties relate to, among other matters, the following:

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We believe the items we have outlined above are important factors that could cause estimates
included in our financial statements to differ materially from actual results and those expressed
in a forward-looking statement made in this report or elsewhere by us or on our behalf. We have
discussed many of these factors in more detail in our Annual Report on Form 10-K for the year ended
September&nbsp;30, 2010. These factors are not necessarily all of the factors that could affect us.
Unpredictable or unanticipated factors we have not discussed in this report could also have
material adverse effects on actual results of matters that are the subject of our forward-looking
statements. We do not intend to update our description of important factors each time a potential
important factor arises, except as required by applicable securities laws and regulations. We
advise our shareholders that they should (1)&nbsp;be aware that factors not referred to above could
affect the accuracy of our forward-looking statements and (2)&nbsp;use caution when considering our
forward-looking statements.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Overview</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We develop, design, manufacture and service custom engineered-to-order equipment and systems for
the management and control of electrical energy and other critical processes. Headquartered in
Houston, Texas, we serve the transportation, environmental, energy, industrial and utility
industries. Our business operations are consolidated into two business segments: Electrical Power
Products and Process Control Systems. Financial information related to these business segments is
included in Note L of Notes to Condensed Consolidated Financial Statements. Revenues and costs are
primarily related to engineered-to-order equipment and systems which precludes us from providing
detailed price and volume information.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The markets that Powell participates in are capital-intensive and cyclical in nature. Cyclicality
is driven by customer demand, global economic markets and potential environmental or regulatory
impacts which affect the manner in which our customers proceed with capital projects. Our
customers have been assessing the short-term demand for oil and electrical energy, the overall
banking environment, the outlook for offshore drilling and related regulatory actions and the drive
towards environmental controls over the type and way energy is produced and utilized. These
factors over the last two years have contributed to decisions by customers to delay or to change
where they place new capital projects, which has driven our backlog of orders to $282.3&nbsp;million
entering fiscal 2011, down $83.5&nbsp;million from the beginning of fiscal 2010. The orders that
comprise our current backlog were taken in a much more competitive environment than the previous
year&#146;s backlog. This increased competition, along with higher commodity prices, will place
downward pressure on gross profit compared to last fiscal year as we work to fulfill these orders
in fiscal 2011.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In December&nbsp;2009, we acquired the business and certain assets of PowerComm Inc. and its
subsidiaries (referred to herein as Powell Canada) for $23.4&nbsp;million, excluding debt assumed of
$15.1&nbsp;million and not including expenses. Powell Canada is headquartered in Edmonton, Alberta,
Canada, and provides electrical and maintenance services. Powell Canada is also a manufacturer of
switchgear and related products, primarily serving the oil and gas industry in western Canada. The
operating results of Powell Canada are included in our Electrical Power Products business segment
from the acquisition date.

fiscal 2011, domestic revenues decreased by 19.1% to $82.7&nbsp;million compared to the second quarter

$42.9&nbsp;million in the second quarter of 2011 compared to $39.9&nbsp;million in the second quarter of

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">decreased by
approximately $10.9&nbsp;million, to $25.6&nbsp;million, as a result of the reduction in volume and pressure
on margins, as discussed above. These two factors also contributed to the decrease in gross profit
as a percentage of revenues decreasing to 20.4% in the second quarter of fiscal 2011, compared to
25.7% in the second quarter of fiscal 2010. We anticipate that gross margin levels will continue
to be depressed over the balance of fiscal 2011 given the overall mix of jobs currently in our
backlog.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the six months ended March&nbsp;31, 2011, consolidated revenues decreased $27.8&nbsp;million to $250.3
million compared to $278.1&nbsp;million for the six months ended March&nbsp;31, 2010. Revenues decreased as a
result of reduced backlog discussed above. For the first six months of fiscal 2011, domestic
revenues decreased by 20.7% to $165.5&nbsp;million compared to the first six months of fiscal 2010.
Total international revenues increased to $84.8&nbsp;million in the first six months of 2011 compared to
$69.3&nbsp;million in the first six months of fiscal 2010. Powell Canada contributed approximately
$16.9&nbsp;million of this increase in international revenues during the first six months of fiscal
2011. Gross profit for the first six months of fiscal 2011, as compared to the first six months of
fiscal 2010, decreased by approximately $22.8&nbsp;million, to $51.5&nbsp;million, as a result of the
reduction in volume and pressure on margins, as discussed above. These factors also contributed to
the decrease in gross profit as a percentage of revenues to 20.6% for the first six months of
fiscal 2011, compared to 26.7% for the first six months of fiscal 2010.

and commercial customers totaled $80.9&nbsp;million in the second quarter of 2011, an increase of $4.1
million compared to the second quarter of fiscal 2010. Municipal and transit projects generated
revenues of $6.9&nbsp;million in the second quarter of fiscal 2011 compared to $9.1&nbsp;million in the

fiscal 2011, compared to 25.2% in the second quarter of fiscal 2010. This decrease in gross profit
as a percentage of revenues resulted primarily from the reduction in volume and pressure on
margins, as discussed above. Gross profit in fiscal 2010 benefitted from the favorable execution
of large projects, as well as cancellation fees and the successful negotiation of change orders on
projects which were substantially completed in prior periods.

reduction in volume and pressure on margins, as discussed above. The gross profit in 2010
benefitted from strong market demand when the projects were negotiated, reduced costs on project
completion from operational efficiencies, a reduced work force, cancellation fees for orders that
were cancelled from our backlog and the successful negotiation of change orders for which the costs
were previously recognized.

Selling, general and administrative expenses were $21.5&nbsp;million for the second quarter of fiscal

due to a $0.6&nbsp;million credit bad debt expense in fiscal 2010 as a result of collections for
previously reserved accounts, along with an increase in depreciation expense. Selling, general and
administrative expenses increased as a percentage of revenues as a result of our decline in

fiscal 2011, compared to $41.7&nbsp;million for the first six months of fiscal 2010. This increase is
primarily related to the acquisition of Powell Canada, increases in commission expense and

31, 2011, respectively, a decrease of approximately $134,000 and $202,000 compared to the three and
six months ended March&nbsp;31, 2010, respectively. The decrease in interest expense was primarily due
to lower amounts outstanding under our credit facilities during the first half of fiscal 2011.

38.3% in the second quarter of fiscal 2011, compared to 35.2% in the second quarter of fiscal 2010.
For the first six months of fiscal 2011, our effective tax rate was 36.4%, compared to 35.2% for
the first six months of fiscal 2010. The effective tax rates for both the second quarter of
fiscal 2011 and the first six months of fiscal 2011 have been negatively impacted by our inability
to record the tax benefit related to pre-tax losses in Canada, offset by favorable changes in the
tax rate for the domestic production activities deduction and the research and development credit
in the United States.

For the six months ended March&nbsp;31, 2011, we recorded net income of $4.9&nbsp;million, or $0.42 per
diluted share, compared to $19.5&nbsp;million, or $1.68 per diluted share, for the six months ended
March&nbsp;31, 2010. Net income for the second quarter of fiscal 2011 was favorably impacted by

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cash and cash equivalents increased to approximately $122.1&nbsp;million at March&nbsp;31, 2011, primarily as
a result of cash flow provided by operations of approximately $8.5&nbsp;million during the first six
months of fiscal 2011. Approximately $8.5&nbsp;million of cash flow from operations resulted from net
income and steps taken to manage our working capital. As of March&nbsp;31, 2011, current assets
exceeded current liabilities by 2.7 times and our debt to total capitalization was 2.1%.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">At March&nbsp;31, 2011, we had cash and cash equivalents of approximately $122.1&nbsp;million, compared to
approximately $115.4&nbsp;million at September&nbsp;30, 2010. We have a $58.5&nbsp;million revolving credit
facility in the U.S. and an additional $6.0&nbsp;million revolving credit facility in the United
Kingdom, both of which expire in December&nbsp;2012. As of March&nbsp;31, 2011, there were no amounts
borrowed under these lines of credit. We also have a $20.0&nbsp;million revolving credit facility,
which is subject to certain limitations as defined in the credit agreement, in Canada. At March
31, 2011, there was no balance outstanding under the Canadian revolving credit facility. Total
long-term debt and capital lease obligations, including current maturities, totaled $6.0&nbsp;million at
March&nbsp;31, 2011, compared $6.9&nbsp;million at September&nbsp;30, 2010. Letters of credit outstanding were
$11.6&nbsp;million at March&nbsp;31, 2011, compared to $15.2&nbsp;million at September&nbsp;30, 2010, which reduce our
availability under our credit facilities. Amounts available under the U.S. revolving credit
facility and the revolving credit facility in the United Kingdom were approximately $46.9&nbsp;million
and $6.4&nbsp;million, respectively, at March&nbsp;31, 2011. Amounts available under the Canadian revolving
credit facility were approximately $15.5&nbsp;million at March&nbsp;31, 2011. For further information
regarding our debt, see Notes H and J of Notes to Condensed Consolidated Financial Statements.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We believe that cash and cash equivalents, projected cash flows from operations and borrowing
capacity under our existing bank revolvers should be sufficient to finance anticipated operations
activities, capital improvements and debt repayments for the foreseeable future. During this
period of market uncertainty, we will continue to monitor the factors that drive our markets. We
will strive to maintain our leadership and competitive advantage in the markets we serve while
aligning our cost structures with market conditions.

fiscal 2011 and approximately $46.0&nbsp;million during the first six months of fiscal 2010. Cash flow
from operations is primarily influenced by demand for our products and services and is impacted as
our progress payment terms with our customers are matched with the payment terms with our
suppliers. Cash flow from operations decreased during the first six months of fiscal 2011 compared
to the same period in the prior year, primarily due to the reduction in income from operations.

During the first six months of fiscal 2011, we received cash of approximately $1.2&nbsp;million from the
sale of our 50% equity investment in Kazakhstan. During the first six months of fiscal 2010, we

The preparation of these condensed consolidated financial statements requires us to make estimates
and assumptions that affect the reported amounts of assets and liabilities, disclosures of
contingent assets and liabilities known to exist at the date of the condensed consolidated
financial statements and the reported amounts of revenues and expenses during the reporting period.
We evaluate our estimates on an ongoing basis, based on historical experience and on various other
assumptions that are believed to be reasonable under the circumstances. There can be no assurance
that actual results will not differ from those estimates.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Outlook</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The markets that Powell participates in are capital-intensive and cyclical in nature. Cyclicality
is driven by customer demand, global economic markets and potential environmental or regulatory
impacts which affect the manner in which our customers proceed with capital projects. Our
customers have been assessing the short-term demand for oil and electrical energy, the overall
banking environment, the outlook for offshore drilling and related regulatory actions and the drive
towards environmental controls over the type and way energy is produced and utilized. These
factors over the last two years have contributed to decisions by customers to delay or to change
where they place new capital projects, which has driven our backlog of orders to $282.3&nbsp;million
entering fiscal 2011, down $83.5&nbsp;million from the beginning of fiscal 2010. The orders that
comprise our current backlog were taken in a much more competitive environment than the previous
year&#146;s backlog. This increased competition, along with higher commodity prices, has placed
downward pressure on gross profit compared to last fiscal year as we work to fulfill these orders
in fiscal 2011.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Growth in demand for energy is expected to continue over the long term. New infrastructure
investments will be needed to ensure the available supply of petroleum products. New power
generation and distribution infrastructure will also be needed to meet the growing demand for
electrical energy. New power generation plants will also be needed to replace the aging facilities
across the United States, as those plants reach the end of their life cycle. A heightened concern
for environmental damage, together with the uncertainty of gasoline prices, has expanded the
popularity of urban transit systems, which should drive demand for investment in transit
infrastructure, contingent upon available financing. Opportunities for future projects continue;
however, the timing and pricing of many of these projects is difficult to predict. The demand for
our products and services should continue to increase as investments in large capital-intensive
infrastructure projects begin to receive funding and support. The increase in our backlog to
$436.6&nbsp;million at March&nbsp;31, 2011 resulted from several large projects awarded related to
petrochemical and offshore oil and gas production which will help solidify our backlog going into
fiscal 2012.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are exposed to certain market risks arising from transactions we have entered into in the normal
course of business. These risks primarily relate to fluctuations in interest rates, foreign
exchange rates and commodity prices.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Interest Rate Risk</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are subject to market risk resulting from changes in interest rates related to our floating rate
bank credit facility. A hypothetical 100 basis point increase in variable interest rates would not
result in a material impact to our financial statements. While we do not currently have any
derivative contracts to hedge our exposure to interest rate risk, we have in the past and may in
the future enter into such contracts. During each of the past three years, we have not experienced
a significant effect on our business due to changes in interest rates.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Foreign Currency Transaction Risk</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have operations that expose us to currency risk in the British Pound Sterling, the Canadian
Dollar and to a lesser extent the Euro. Amounts invested in our foreign operations are translated
into U.S. Dollars at the exchange rates in effect at the balance sheet date. The resulting
translation adjustments are recorded as accumulated other comprehensive income (loss), a component
of stockholders&#146; equity in our consolidated balance sheets. We believe the exposure to the effects
that fluctuating foreign currencies have on our consolidated results of operations is limited
because the foreign operations primarily invoice customers and collect obligations in their
respective currencies or U.S. Dollars. Our international operations are financed utilizing local
credit facilities denominated in local currencies. Additionally, expenses associated with these
transactions are generally contracted and paid for in the same local currencies. A 10% unfavorable
change in the U.S. Dollar exchange rate, relative to other functional currencies in which we

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">During fiscal 2010 and the first half of fiscal 2011, we entered into nine foreign currency forward
contracts to manage the volatility of future cash flows on certain long-term contracts that are
denominated in the British Pound Sterling. The contracts are designated as cash flow hedges for
accounting purposes. The changes in fair value related to the effective portion of the hedges are
recognized as a component of accumulated other comprehensive income on our Condensed Consolidated
Balance Sheets. At March&nbsp;31, 2011, we recorded a net liability of approximately $17,900 on our
Condensed Consolidated Balance Sheets related to these transactions.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are subject to market risk from fluctuating market prices of certain raw materials. While such
materials are typically available from numerous suppliers, commodity raw materials are subject to
price fluctuations. We attempt to pass along such commodity price increases to our customers on a
contract-by-contract basis to avoid a negative effect on profit margin. While we may do so in the
future, we have not currently entered into any derivative contracts to hedge our exposure to
commodity risk. We continue to experience price volatility with some of our key raw materials and
components. Fixed price contracts may limit our ability to pass cost increases to our customers,
thus negatively impacting our earnings. Fluctuations in commodity prices may have a material impact
on our future earnings and cash flows.

receivable or costs and estimated earnings in excess of billings on uncompleted contracts. The
amounts recorded may be at risk if our customers&#146; ability to pay these obligations is negatively
impacted by economic conditions. Our customers and their industries are typically engineering
procurement and construction firms, oil and gas producers, oil and gas pipelines, refineries,
petrochemical plants, electrical power generators, public and private utilities, co-generation
facilities, mining/metals operations, pulp and paper plants, transportation authorities,
governmental agencies and other large industrial customers. We maintain ongoing discussions with
customers regarding contract status with respect to payment status, change orders and billing terms

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">must reflect the fact that there are resource constraints, and the benefits of controls must
be considered relative to their costs. Further, because of the inherent limitations in all control
systems, no evaluation of controls can provide absolute assurance that misstatements due to error
or fraud will not occur or that all control issues and instances of fraud, if any, within the
Company have been detected. These inherent limitations include the realities that judgments in
decision-making can be faulty and breakdowns can occur because of simple errors or mistakes.
Controls can be circumvented by the individual acts of some persons, by collusion of two or more
people or by management override of the controls. The design of any system of controls is based in
part on certain assumptions about the likelihood of future events, and there can be no assurance
that any design will succeed in achieving its stated goals under all potential future conditions.
Over time, controls may become inadequate because of changes in conditions or personnel, or
deterioration in the degree of compliance with policies or procedures. Because of the inherent
