conservative capital structure. IES has not drawn on its existing facility since
April 2002.  As of March 31, 2003,  we have $26.1 million in cash on our balance
sheet and have provided  guidance that we expect to generate between $30 million
and $40  million of free cash flow this fiscal  year,  defined as cash flow from
operations less capital expenditures." The amendment to the credit facility will
be filed on May 28, 2003 with the Securities and Exchange  Commission ("SEC") on
Form 8-K.

         Additionally,  IES  announced  today that it has updated its "Company &
Investment   Profile"   which  can  be  found  on  the   company's   website  at

Summary - -------------------------------------------------------------------------------- Integrated Electrical Services ("IES" or the "Company") is the largest single source provider of electrical contracting services in the United States. It provides a broad range of services including designing, building, maintaining and servicing electrical systems including data communications for commercial, industrial and residential customers. The Company is headquartered in Houston, Texas. Since the Company's inception in 1997, it has developed a national footprint of approximately 150 locations currently serving the continental 48 states with concentration in the Sunbelt. At the time of its IPO in January 1998, the Company had run-rate revenues of approximately $313 million. Since that time, IES has grown rapidly through acquisitions and internal growth. From 1997 to 2002, revenues increased at a compounded annual growth rate of approximately 47%. Included in that growth was approximately 8% organic or "same store sales" growth compared to an industry growth rate of 5%, according to F.W. Dodge, during the same period. EXHIBIT 1 IES HAS A NATIONWIDE PRESENCE IES OPERATES IN 150 LOCATIONS ACROSS THE U.S. (U.S. MAP) IES' business includes providing system design, installation, maintenance and service to general contractors, developers and companies of all sizes. IES has two business segments, Commercial/Industrial and Residential. In 2002, 81% of revenues were from Commercial/Industrial and 19% of revenues were from Residential. IES' service and maintenance work is done within the Commercial/Industrial segment and accounted for 10% of IES' Commercial/Industrial revenues. Shortly after being named CEO in October 2001, H. Roddy Allen led the implementation of a three-phase strategic plan to strengthen the Company during the recent reduction in construction spending, further integrate the Company and focus on future growth. The first phase of the strategy, Back to Basics, is largely in place and is an ongoing process. Phase II, One Company. One Plan. is underway, and focuses on the integration of the Company. Phase III, Continued Growth, will seek to grow the Company via internal and acquisition-driven growth. 5

As part of Phase III, IES will consider compelling acquisition opportunities. In February 2003, IES acquired substantially all the assets of Encompass Electrical Technologies - Rocky Mountains, Inc. (formerly known as Riviera Electric), a provider of electrical contracting services based in Denver, Colorado, with locations throughout the state of Colorado. The assets acquired by IES generated revenues of $84 million for the calendar year ended December 31, 2002. The purchase price was $2.7 million net of cash acquired plus the assumption of certain liabilities. 6

Three-Phase Strategic Plan The strategic plan is a multi-year three-phase plan with Phase I actions to build backlog, control costs, and generate strong cash flow; Phase II actions to integrate IES' subsidiaries; and finally Phase III to focus on continued growth. The three phases of the plan are detailed in Exhibit 2 below: EXHIBIT 2 A WELL-DEFINED AND SUCCESSFUL STRATEGY - ----------------------------------------------------------------------------------------- Phase I Phase II Phase III - ----------------------------------------------------------------------------------------- BACK TO THE BASICS ONE COMPANY. ONE PLAN.

EXHIBIT 3 IMPROVED PERFORMANCE OPERATING INCOME MARGIN IN 2002 IMPROVED IN EACH QUARTER THROUGHOUT THE YEAR. (Dollars in Millions) 1Q02 2Q02 3Q02 4Q02 2002 - -------------------------------------------------------------------------------- Revenues $375.2 $356.5 $374.8 $368.9 |$1,475.4 Operating Income Before | One-Time Charges* 7.5 11.3 18.6 22.0 | 59.4 GAAP Operating Income 3.5 9.8 18.6 10.1 | 41.8 Diluted EPS Prior to Charges* $0.02 $0.08 $0.19 $0.22 | $0.50 | Restructuring Charges ($0.06) ($0.03) - - | ($0.09) One-Time Charges - - - (0.16) | (0.16) Diluted EPS ($0.04) $0.05 $0.19 $0.06 | $0.25 | Gross Margin 15.3% 15.3% 15.6% 17.1% | 15.8% Operating Income Margin Before | One-Time Charges* 2.0% 3.2% 5.0% 6.0% | 4.0% GAAP Operating Income Margin 0.9% 2.7% 5.0% 2.7% | 2.8% Cash flow from Operations ($2.5) $12.3 $37.5 $6.1 | $53.4 * Before one-time charges of $15.2 million ($9.9 million after tax) for reorganizing the business and an increase in accruals for self insurance liabilities. 7

As the impact of the implementation of Back to Basics was realized throughout fiscal 2002, the Company showed steady and significant improvement in key profitability metrics on a quarterly basis, despite posting its strongest revenues in the first quarter. Operating income margins more than doubled over the four-quarter period while EPS prior to one-time charges increased from $0.02 per share in the first quarter to $0.22 in the fourth quarter. IES has focused on doing business more efficiently in order to improve profitability in this tighter market. Examples include: the national procurement program which has strengthened IES' relationship with vendors and reduced its overall cost to procure goods; the focus on serving customers on a more national basis allowing for cost savings from repeat projects; and the initiative to reduce overhead costs. Build Backlog Backlog is a key indicator of the future revenues of the Company, and building that backlog was a primary element of Back to Basics. IES was able to increase its backlog in 2002 in a market where commercial and industrial construction spending was down 18%, according to statistics from F.W. Dodge. The primary components of backlog are commercial and industrial projects, since most service work (except for long-term service contracts) and most single-family residential projects are not included in backlog due to the short-term nature of the projects. The Company's strong backlog performance serves to highlight the advantages of its size and diverse customer base, and helps it navigate through difficult economic periods. The table below demonstrates how IES has increased its backlog over the last three years. The Company divested three non-core businesses in 2002, and the backlog associated with these divestitures was removed in each year. At the end of the second quarter of 2003 IES had backlog of $798 million. EXHIBIT 4 RECORD BACKLOG IN FISCAL 2002 DESPITE WEAK CONSTRUCTION SPENDING IN 2002 IES' BACKLOG INCREASED BY $12 MILLION, WHILE THE COMMERCIAL AND INDUSTRIAL CONSTRUCTION MARKET WAS DOWN 18%. BACKLOG GROWTH* (BAR CHART) (Dollars in Millions) 1999 $644 2000 $726 2001 $789 2002 $801 Q2 2003 $798 * Prior years have been restated to exclude divestitures. Backlog includes project work which the Company has a signed contract for, but is not yet complete. 8

Control Costs Reigning in costs is a key element of the Back to Basics strategy. Throughout 2002, particular effort was focused on reducing selling, general and administrative ("SG&A") costs. By the fourth quarter, significant progress had been made; that quarter's SG&A was only $41.1 million versus $57.3 million a year earlier. This is a 28% reduction, as summarized in Exhibit 5. IES continues to lower costs in 2003, and in the second quarter selling general and administrative costs were $37.5 million, a $3.6 million reduction over fourth quarter levels and an 8.8% improvement in the overall cost structure of the firm. EXHIBIT 5 SIGNIFICANTLY LOWER SG&A COSTS IES REDUCED SG&A EXPENSES BY 28% IN FISCAL 2002. (Dollars in Millions) 4Q 2001 4Q 2002 ---------- ---------- Corporate SG&A decreased 59% $ 11.0 $ 4.5 Field SG&A decreased 21% 46.3 36.6 ---------- ---------- Overall SG&A decreased 28% $ 57.3 $ 41.1 In conjunction with these cost-saving efforts, IES took a $4.0 million restructuring charge against earnings in the first quarter of 2002 and a $1.6 million charge in the second quarter of 2002, associated primarily with workforce reductions. These charges reduced earnings per share by about $0.09 per share for fiscal 2002. With costs reduced and the Company streamlined, IES is now well positioned to take advantage of future economic growth. Focus on Cash Flow Management has been successful in improving free cash flow generation (cash flow from operations less capital expenditures). Cash flow from operations increased from $8.6 million in 2001 to $53.4 million in 2002. Meanwhile IES was able to reduce capital expenditures from $25.8 million in 2001 to $11.9 million in 2002. IES' 2002 free cash flow was an all-time high of $41.5 million, a positive swing of $58.7 million from fiscal 2001's cash flow use ($17.2) million. IES' guidance for free cash flow generation in 2003 is between $30 million and $40 million and in the first six months of fiscal 2003 IES has already generated free cash flow of $13.3 million. IES presents free cash flow because management believes it is a good measure of cash available for shareholders. Exhibit 6 illustrates the free cash flow generation over the past four years and 2003 projected free cash flow. EXHIBIT 6 RECORD LEVELS OF FREE CASH FLOW IN FISCAL 2002 FREE CASH FLOW* ----------------------------- 1999 -19.9 2000 14.8 2001 -17.2 2002 41.5 2003P 30.0 - 40.0 * Cash Flow from Operations less Capital Expenditures. 9

In addition to the large reduction in SG&A expenses, better management of working capital helped increase cash generation. Days Sales Outstanding ("DSO") in accounts receivable, a measure of capital tied up in financing receivables, was 81 days in the first quarter of 2001. Renewed focus on collecting receivables reduced this figure by 8 days to 73 days in the first quarter of 2002. DSO's fell a further 3 days to 70 by the third quarter, and closed out the year at 73 days at the end of the fourth quarter. The eight-day swing in DSOs represented about $32 million in cash. At the end of the second quarter of 2003, DSOs were 78 days. The table below illustrates how IES' move from a significant growth phase into an integrated company is positively impacting its capital structure: EXHIBIT 7 CASH FLOW TRENDS ILLUSTRATE INTEGRATION IES IMPROVED ITS FREE CASH FLOW GENERATION BY $58.7 MILLION IN FISCAL 2002. (Dollars in Millions) 1999 2000 2001 2002 ------------ ------------ ------------ ------------ CASH FLOW FROM OPERATIONS $ (6.3) $ 43.2 $ 8.6 $ 53.4 CAPITAL EXPENDITURES (12.9) (28.4) (25.8) (11.9) ------------ ------------ ------------ ------------ FREE CASH FLOW $ (19.2) $ 14.8 $ (17.2) $ 41.5 ACQUISITION EXPENDITURES (106.5) (33.2) (0.2) -- DIVESTITURE PROCEEDS -- -- -- 7.5 ------------ ------------ ------------ ------------ CASH FLOW AFTER ACQ/DIVEST $ (125.7) $ (18.4) $ (17.4) $ 49.0 DECREASE (INCREASE) IN DEBT $ (137.5) $ (16.0) $ (44.0) $ 39.1 As shown in the table, negative cash flow from operations and a high level of spending characterized 1999. IES was focused on acquisition growth and spent over $100 million in cash to acquire some 40 electrical contractors with about $415 million in annualized revenues. In 2000, IES slowed its aggressive acquisition growth goals and focused on integration. Acquisition spending fell to $33 million in cash for 2000 and ceased in 2001. In 2002, with Back to Basics implemented, acquisition spending eliminated and capital expenditures reduced, free cash flow increased sharply. IES also streamlined its business by divesting non-core and/or under performing operations, raising another $7.5 million in cash. IES EXPECTS TO GENERATE BETWEEN $30 MILLION AND $40 MILLION OF FREE CASH FLOW IN FISCAL 2003. IES will continue to work diligently to maximize cash flow generation. In addition to focusing on an efficient base business and controlling capital expenditures, IES is proactive in reviewing and implementing tax planning opportunities. As a result of effective tax planning, IES expects to reduce cash taxes paid in 2003 and 2004 and expects this to improve the Company's free cash flow and contributes to IES' expectation to generate between $30 million and $40 million in free cash flow. This is an increase over the original guidance given in December of at least $20 million to $30 million in free cash flow. FINANCIAL REENGINEERING Across all three phases of IES' strategic plan, IES is reengineering the Company's capital structure. IES is utilizing its free cash flow to set a solid foundation for the future. The Company reduced debt by $39.1 million in fiscal 2002, and in August of 2002, it began a two million share common stock repurchase program. Through March 31, 2003 IES has repurchased about 1.1 million shares under the program, further confirmation of management's belief that IES is on the right track and positioned to generate significant free cash flow. The Company plans to continue to retire debt over the next two to three years as long as the price of IES' debt remains attractive, and plans to reduce total debt levels to under $200 million from its $249 million level today. 10

IES had a $150 million credit facility led by JP Morgan that was undrawn. On May 27th, 2003, IES extended its facility for an additional two years from May 2004 to May 2006. At the time of the extension, IES reduced the size of its facility from $150 million to $125 million in keeping with the Company's more conservative capital structure. However, there is an accordiaon feature in the facility such that IES can increase the facility to $150 million. At the time of the extension, the covenant requirements for IES' Debt to EBITDA ratio were changed from 3.50x in June 2003 to 3.75x in June and there after it was changed from 3.25x to 3.75x in September, 3.5x in December and down to 3.25x in June 2004 and thereafter. The EBIT to Interest coverage ratio was changed from 2.50x in June to 2.00x and up to 2.25x in September and then up to 2.50x in March 2004 and thereafter. In addition, the provisions of the extension limit the amount of outstanding debt and capital stock that can be repurchased to the lesser of $70 million or $30 million plus 50% of cumulative net income if there is no outstanding balance on the facility. If there is an outstanding balance on the facility it is the lesser of $50 million or $30 million plus 50% of cumulative net income. Additionally, capital stock purchases are limited to $20 million in aggregate. IES has not drawn on the current facility since April 2002 and as of March 31st, 2003, IES had $26.1 million in cash on its balance sheet. Current cash levels combined with the lack of current financing needs allowed IES to reduce its facility to $125 million. Reducing the facility saved IES approximately $160,000 at the time of the extension and will save the Company approximately $160,000 each year through 2006 in annual commitment fees for the undrawn portion of the facility. PHASE II - ONE COMPANY. ONE PLAN. With Back to Basics in place and its benefits ongoing, management moved to Phase II of its strategic plan, One Company. One Plan. The primary goal of One Company. One Plan. is to achieve a higher level of integration among the operating units. Even with the divestiture of under-performing subsidiaries and the combination of some subsidiaries, IES can further streamline the organization and recognize significant value from increased integration. The focus of Phase II is instituting a regional structure, implementing a unified financial planning and reporting system, unifying employee programs and incentives, further improving the Company's safety record, generating savings through a centralized procurement program and servicing customers on a more national basis. Early results indicate that the program is on track to be as successful as Back to Basics. Regional Structure IES has implemented a regional structure with six Regional Operating Officers reporting directly to the Chief Operating Officer, Rick China and the Chief Executive Officer, H. Roddy Allen. For 2003, corporate planning was done on a regional basis and incentive plan goals are based on regional targets. This has already created a stronger team environment within each region; the subsidiaries are more frequently sharing customers and jointly executing projects. Financial Reporting and Planning System The financial planning and reporting system, Forefront, has been implemented at 70% of the Company's subsidiaries. This system allows IES direct access to detailed subsidiary financials at any time and gives each subsidiary enhanced project management tools. The system has already helped IES to shorten the monthly financial closing process by two to three days. Employees IES has established a common healthcare plan throughout the Company. In addition, IES has put in place a common field incentive and bonus plan focused on overall corporate performance, as well as regional performance. IES' executive incentive plan, while discretionary, is structured so that executives and subsidiary leaders may receive up to a target bonus compensation when IES achieves certain levels of profitability. Safety IES' focus on safety is generating continuously improving performance. Recordable accidents, a key safety measure, have dropped from 9.72 per 100 employees in fiscal 2000 to 3.04 per 100 employees in the first half of 2003, as shown in Exhibit 8 below. The 11

industry average is approximately eight recordable accidents per 100 employees according to the Bureau of Labor Statistics, so IES has improved to less than half the industry average. In addition to protecting its workers, this should lead to lower insurance costs. EXHIBIT 8 PHASE II INITIATIVES PRODUCING TANGIBLE RESULTS IES' RECORDABLE ACCIDENTS ARE LESS THAN HALF THE INDUSTRY AVERAGE. RECORDABLE ACCIDENTS (per 100 employees) (BAR CHART) 2000 9.72 2001 6.41 2002 4.65 2003 YTD 3.04 Source: Company records. Procurement The national procurement initiative is generating positive results. At the end of fiscal 2001, IES began forging relationships and alliances with manufacturers, service providers and distributors. The relationships have created more consolidated purchasing on the part of IES and the benefits include improved pricing, volume-based rebates, increased service commitments, funding of IES company-wide in-house procurement tools and partial sponsorship of Company events. As part of this initiative, IES implemented a system that allows the Company to track the majority of the goods and services purchased. In 2001, IES could only track 30% of its procurement spending. Today that percentage is over 70% and IES' goal is to reach over 90% by the end of 2003. In 2002, IES earned $2.1 million in volume based incentives and, as a result of this initiative, has reduced the direct cost of goods and services purchased. IES expects increased benefits from the program during this fiscal year. Customers IES is committed to managing relationships with nation-wide customers and providing services to larger customers across the country. IES maintains a customer database so projects across all subsidiaries are tracked and the data is available in one centralized location. This database is particularly important due to IES' unique triangular relationship with its customers. IES typically works for a general contractor; however, the ultimate customer is the end user, such as Walgreen's or 3M. It is key for IES to maintain and foster relationships with both of these groups and it has become a particular focus of the Company. 12

PHASE III - CONTINUED GROWTH Phase III will be implemented as market conditions begin to improve. However, IES will consider compelling growth opportunities as they present themselves, as was the case with Riviera Electric in Colorado. With the implementation of Phases I and II, the foundation for effective growth is substantially in place. The Company is more streamlined and efficient and is functioning more as a unified organization than a federation of different entities. The Company's acquisition and expansion plans will be strategically focused and will occur at a manageable pace, with strategic fit and acquisition quality being the drivers of the process. In the case of Riviera, the state of Colorado is projected to have 7% compound annual growth in construction spending over the next three years, which is over three times the projected U.S. construction growth level. Previously, IES did not have a strong presence in Colorado. Backlog for work to be completed in the state of Colorado was $7.7 million as of December 31, 2002. Riviera had backlog of $23 million in December of 2002 and at the beginning of calendar 2002, (prior to the bankruptcy filing of the previous owner, Encompass Services), Riviera had backlog of approximately $48 million. IES believes over time it will be able to build that backlog back up since Riviera had not added significant projects since July 2002 as a result of Encompass' financial difficulties. EXHIBIT 9 GROWTH IN CONSTRUCTION SPENDING IN COLORADO COLORADO IS EXPECTED TO GROW THREE TIMES AS FAST AS THE OVERALL U.S. CONSTRUCTION MARKET.

Dodge December 2002. CAGR = Compound Annual Growth Rate. Riviera has locations in Denver, Colorado Springs, Loveland, Boulder, Silverthorne, Eagle, and Aspen, Colorado and provides electrical contracting services to the commercial, industrial, service and retrofit markets. In calendar 2002, Riviera had strong financial performance, with revenues of $84 million, and pro forma EBITDA of $7.6 million. Riviera has historically generated gross margins between 19.5% and 21.5% and has been able to keep SG&A as a percentage of revenues between 10.5% and 11.0% for an operating income margin of 8.5% to 10.5%. Given the current condition of Riviera and the depressed backlog levels as a result of the stress Encompass' financial difficulties created, it is unlikely that Riviera will be able to generate comparable returns in 2003. However, IES expects at this time that the transaction will be accretive to earnings in fiscal 2003 and the acquisition will return to its prior performance over time. IES filed a Form 8-K with the SEC on May 12, 2003 which includes the audited financial statements for Riviera Electric. 13

Recent Financial Results and Guidance - -------------------------------------------------------------------------------- IES REPORTED EARNINGS OF $0.09 PER SHARE, WITHIN THE GUIDANCE RANGE FOR THE SECOND QUARTER OF 2003. The Second Quarter The Company posted earnings for the fiscal second quarter ended March 31, 2003 of $0.09 per share versus $0.08 per share a year ago. The $0.08 a year ago is prior to a restructuring charge of $0.03. Results for the quarter were within the previously issued guidance of $0.08 to $0.12 per share. Revenues were $343.1 million versus $356.5 million a year ago. This was a 3.7% decline reflecting $12.2 million of lost revenues on divested or closed subsidiaries that were included in revenues for the second quarter last year, but not during the second quarter this year, and unfavorable weather conditions in the northeast and the south. Highlights of the second quarter included: * SG&A as a percentage of revenue fell 130 basis points to 10.9% of revenues from 12.2% one year ago. * $187 million of new larger project work was added to backlog. * Free cash flow generation of $12.6 million. Free cash flow is cash flow from operations less capital expenditures and management believes it is a good measure of cash available for shareholders. * Through March 31, IES has repurchased 1.1 million shares under its stock repurchase program announced last August. IES added $187 million of new larger project work, which is defined as projects greater than $300,000, to backlog during the second quarter compared to $155 million added during our first fiscal quarter of 2003 and $108 million added in our second fiscal quarter of 2002. Backlog at the end of the second quarter of 2003 was $798 million compared to $766 million at the end of the first fiscal quarter of 2003 and $783 million at the end of the second fiscal quarter of 2002. $187 MILLION OF NEW LARGER PROJECT WORK WAS ADDED TO BACKLOG IN Q2 2003. Review of New Projects in the second quarter: * $28 million of manufacturing and heavy industrial projects * $22 million of high-rise hotel and condominium and mid-rise apartment projects * $21 million of work at retail centers * $21 million of work at schools and community centers * $20 million of work at office buildings * $13 million of new healthcare projects * $8 million of wastewater treatment facility work The $28 million increase in manufacturing and heavy industrial projects is a significant increase to that category from 7% of total backlog in the first quarter of fiscal 2003 to 9% of backlog in the second quarter. In addition the $20 million increase in office building projects increases that category from 5% of total backlog in the first quarter of fiscal 2003 to 7% of total backlog in the second quarter. 14

IES REPORTED EARNINGS OF $0.10 PER SHARE, AT THE TOP OF THE GUIDANCE RANGE FOR THE FIRST QUARTER OF 2003. The First Quarter The Company posted earnings for the fiscal first quarter ended December 31, 2002 of $0.10 per share versus $0.02 per share a year ago. The $0.02 a year ago is prior to a charge for adoption of SFAS 142 and a restructuring charge. Results for the quarter were at the top of the previously issued guidance of $0.06-$0.10 per share. Revenues came in at $348.6 million versus $375.2 million a year ago. This was a 7% decline reflecting divestitures of non-core assets in the fourth quarter of 2002, a significant slow down in telecommunications work versus a year ago and continued weakness in the commercial and industrial construction market. See Exhibit 10 below for a detailed breakdown of the decrease in revenues versus the first quarter of 2001. IES continued to have record performance from its residential division, as the residential construction market remains quite robust. IES' residential revenues were $76.9 million for the first quarter of 2003 versus $67.1 million for the period one year ago which is a 14.6% increase. EXHIBIT 10 Q1 2003 VERSUS Q1 2002 CHANGES IN REVENUES - ----------------------------------------------------------------- (Dollars in Millions) Change in Revenues - ----------------------------------------------------------------- Divestitures ($14) Telecommunications ($10) Commercial/Industrial ($12) Residential/Other $8 - ----------------------------------------------------------------- Highlights of the first quarter included: * SG&A as a percentage of revenue fell over 200 basis points to 11.1% of revenues from 13.3% one year ago. * $155 million of new larger project work was added to backlog. * Operating margin increased 170 basis points to 3.7%. * Free cash flow was positive at $0.7 million in a quarter that normally uses cash. Free cash flow is cash flow from operations less capital expenditures and management believes it is a good measure of cash available for shareholders. Backlog for the quarter was down to $776 million versus a record $801 million in the fourth fiscal quarter of 2002. This is a typical seasonal decline. The decline in SG&A expense and the generation of free cash flow continues to demonstrate the success of the Company's Back to Basics program. SG&A expense for the quarter was $38.6 million versus $49.8 million a year ago, a decrease of 22.5%. $155 MILLION OF NEW LARGER PROJECT WORK WAS ADDED TO BACKLOG IN Q1 2003. Review of New Projects in the first quarter: * $33 million of high-rise hotel, condominium and mid-rise apartment projects * $24 million of new healthcare projects * $20 million of wastewater and water treatment facility work * $19 million of work at retail centers * $17 million of work at school and community centers * $11 million of manufacturing and heavy industrial projects * $7 million of work at office buildings The $20 million increase in wastewater and water treatment facilities is significant and increased that category from 2% of backlog to 4% of backlog. 15

Fiscal Q3 2003 and Full-Year 2003 Financial Guidance For the third fiscal quarter, management expects to earn between $0.14 and $0.20 per share. Guidance for the full year fiscal 2003 is unchanged at $0.53 to $0.60 per share with free cash flow (cash flow from operations less capital expenditures) of $30 to $40 million.

Company Overview - -------------------------------------------------------------------------------- Founded in 1997 to consolidate the electrical contracting business, IES quickly grew to become the largest provider of electrical services in the industry with revenues of approximately $1.5 billion. IES provides a broad range of electrical services including designing, building and maintaining both low and high voltage electrical systems for commercial, industrial, municipal, utility, and residential customers. EXHIBIT 12 IES' GEOGRAPHIC DIVERSITY OF BACKLOG - 03/31/03 (PIE CHART) Southeast 36% South 31% Northwest 3% Northeast 6% Mid Atlantic 13% Midwest 4% Southwest 7% IES' national presence mitigates the region specific economic slowdowns. IES' presence in the southwest and in Florida has been particularly beneficial through this most recent construction decline because these areas were less impacted than some of the other regions of the U.S. Since 1997, much of the Company's revenues have been derived from the fast growing Sunbelt states. These states stand to benefit from expected favorable population movement over the next decade. A diverse revenue mix- The Company services a wide variety of customers which also cushions it from sector declines. The impact of a slowdown in a particular industry tends to be muted when compared to its smaller, more geographically concentrated competitors. In addition, IES' expertise in a variety of industries allows it to be flexible and to share its expertise across regions. For instance, with the recent increase in healthcare construction spending, one of the Company's subsidiaries, whose specialty is healthcare facilities construction, trained and aided other IES subsidiaries so the Company is able to perform complex healthcare projects across the U.S. 17

EXHIBIT 13 IES' DIVERSITY OF CLIENTS HAS SERVED IT WELL IN A TOUGH ECONOMIC ENVIRONMENT CURRENT MIX OF BACKLOG - 3/31/03 (BAR CHART) Hotels/Condos 13% Health Care 13% Utilities 12% Institutions 13% Apartments 8% Airports 7% Heavy Industry/Manufacturing 9% Other Commercial 5% Retail 5% Office Buildings 7% Highway 4% Communications 2% Government 1% Service 1% Nationwide presence- The Company's nationwide presence and name recognition helps it to compete for larger, national contracts with customers that operate throughout the U.S. This represents a growing market and IES has made significant progress in pursuing these sizable accounts. A few of IES' current national customers include Wal-Mart, Marriott, Nordstrom's, Intel, Starbucks, Ryland Homes and Pulte Homes. Given its size, IES still maintains customer diversity because no single customer accounts for more than 10% of total revenues. Additionally, IES believes its size and national service offering uniquely positions it as the only single source non-union electrical contracting service provider able to execute projects on a national basis. IES is able to take on very large, and complex projects often with a national scope that would strain the capabilities and resources of most of its competitors. Strong growth opportunities- The Sunbelt focus, as well as market share gains, and customer satisfaction have helped IES grow organically about 3% faster than the construction industry as a whole over the last several years. Over 50% of business is from repeat customers. Currently, over 70% of the Company's revenues come from sunbelt states. According to F.W. Dodge, in 2003 sunbelt states are projected to have slightly positive growth versus a 2% decline across the entire U.S. In 2004, Sunbelt states are projected to have a 6% growth rate versus 5% for the entire U.S. 18

Access to Resources - Access to resources is key to success especially in this difficult environment. Many of IES' competitors have reduced access to both bonding capacity and capital, which is constraining their ability to effectively compete and bid on many jobs. As a result of size and track record, IES has more than adequate capacity. This, in conjunction with IES' access to a $125 million credit facility, provides a significant competitive advantage over most of its local competitors. IES is able to bid on larger projects that require bonding and working capital. Proprietary Systems and Processes - IES has proprietary systems and processes which help the Company bid on projects, manage projects once they have been awarded and maintain and track customer information. In addition, IES has developed and perfected techniques and processes for installation on a variety of different projects including its prefabrication process that have been implemented throughout the organization. Through the consolidation of over 85 entities, IES has taken the best practices and leveraged those systems and processes across the entire organization for best in class practices. Utilization of Prefabrication Processes - IES' size and 100% merit shop environment has allowed the firm to quickly implement best practices across the Company as it relates to prefabrication. IES has invested in and utilizes prefabrication facilities to pre-assemble electrical components that can later be installed on site. This is safer, more cost effective and more efficient for IES and the customer. IES has prefabrication centers strategically located to service the U.S. for larger scale projects. 19

Operations Overview IES has two principal operating segments (1) Commercial/Industrial and (2) Residential. For the year ended September 30, 2002, the Commercial/Industrial segment accounted for approximately 81% of revenues and Residential made up the remainder. Exhibit 14 below illustrates IES' revenue by type of work over the past 5 years and shows the increase in communications work in 2000 and 2001 and then the fall-off as the communications infrastructure was overbuilt. Note that the Commercial/Industrial segment data for segment reporting purposes contains both the communications and the service and maintenance business segments, which had previously been reported separately. Residential revenues increased 11%, while Commercial/Industrial revenues declined in 2002 as a result of the 18% decrease in commercial and industrial construction spending in 2002. EXHIBIT 14 HISTORICAL REVENUES BY TYPE REVENUE BY TYPE (Dollars in Millions) 1998 1999 2000 2001 2002 6 Months 2003 - --------------------------------------------------------------------------------------------------- Commercial and Industrial $238 $716 $1,127 $1,120 $1,002 $459 Residential $111 $176 $251 $257 $282 $135 Service and Maintenance $35 $69 $132 $136 $119 $52 Communications $3 $74 $163 $180 $72 $46 Segment data for the last three fiscal years is detailed on the following page in Exhibit 15. 20

Over that time period, higher margin projects in backlog were replaced with lower margin jobs as the bidding environment became more competitive and the number of new projects declined. While over 70% of IES' work is from new construction, when there is a decrease in construction spending, renovation and service work increases because businesses and individuals modify or renovate the old in favor of building new facilitates. That trend is demonstrated in the increase in IES' revenues from renovation work from 19% in 2001 to 22% in 2002. However, that trend appears to be changing and in the first six months of fiscal 2003 with new construction actually increasing to 73% of total revenues and only 19% from renovation and 8% from service and maintenance. See Exhibit 16 on the next page. 21

Commercial projects include: high-rise structures such as hotels, apartment buildings, condominiums and office building; retail stores and centers; hospitals and healthcare facilities; schools and community centers including stadiums and arenas; and projects specifically related to low voltage installations including communications. Industrial projects include: manufacturing and heavy industrial facilities; distribution centers; utility and power generation, including substations and power line installation; high-technology centers; water and wastewater treatment facilities; government and military installations; airports; and highway projects. Below is a list of IES' top general contractor customers in the Commercial/Industrial market and the top end customers sorted alphabetically. IES typically works for a general contractor although in some cases the Company does work directly for the end user. IES is awarded work as a result of both of these relationships and the Company is focused on fostering relationships and maintaining customer satisfaction with the end customer as well as the general contractor. 22

It is common for IES to take on long-term service contracts with end customers. Residential IES is the largest residential electrical contractor in the country. IES' residential segment is composed of three different types of projects: single family homes, often tract homes with entire subdivisions built at one time; high-end single family custom homes, which are often quite large and typically include the latest trends in security and technology; and multifamily low rise apartments, condominiums and town homes. IES works for some of the largest single family and multifamily developers in the country. See Exhibit 18 for IES' top customers by residential project type sorted alphabetically. 23

Organizational Systems, Processes and Controls Overview IES has in place an integrated system of internal controls, including management of operations, information systems and financial activities. These controls complement the regional operating structure established under the Company's One Company. One Plan. strategy and are designed to provide a framework of procedures, monitoring systems and certifications that enable the Company to ensure compliance with company policies as well as applicable rules and laws. Although IES management believes an effective structure is in place to manage the business there are inherent risks in the contracting industry especially as it pertains to fixed bid contracts that sometimes experiences fade in profitability over the life of the contract. Although the structure and controls are in place to minimize this and other risks, there is no guarantee that IES will not experience financial difficulties as a result of these risks. See the disclosure statement on page 4 for additional risk factors. Management structure The Company's Executive Committee, comprised of the Chief Executive Officer, Chief Operating Officer, Chief Financial Officer, Chief Technology and Procurement Officer, Senior Vice President of Operations and Senior Vice President of Human Resources, monitors the Company's operations and its progress on the three-phase strategy. The Executive Committee is supplemented by a regional operating structure consisting of six geographically based regions. The regions are led by Regional Operating Officers ("ROOs") that report directly to the Company's Chief Operating Officer and Chief Executive Officer. Each ROO is supported by a Regional Controller ("RC"), that is responsible for monitoring the financial aspects of operations at each of the subsidiaries within the region. Together the ROO and RC maintain control and consistent application of policies and procedures throughout the Company. Together they provide a control environment to address financial operating results and issues, as well as upcoming events, opportunities or concerns, and carry out company initiatives. At the end of each quarter, the regions host a series of "Home and Away" meetings. The CEO, COO, CFO, Regional Operating Officers and the Presidents of the subsidiaries attend these Home & Away meetings. Every other quarter, regions conduct these meetings at or near their "home" locations and on opposite quarters attend an "away" meeting at the home office in Houston. These meetings facilitate face-to-face sharing of results, events, opportunities and concerns and allow for sharing of best practices and cross-selling among the subsidiaries. Information Systems All of the Company's locations are joined on a common Wide Area Network ("WAN"). This platform enables the Company to access and monitor the computer servers at each subsidiary location and facilitates efficient communication across the Company. Stringent controls are in place limiting access to the data stored on each location's server. The Company is approximately 70% complete in the implementation of a fully integrated Enterprise Resource Planning ("ERP") system known as Forefront. The Company expects 25

that this implementation will be substantially complete by December 2003. This system, while allowing real time access to subsidiary and project data, facilitates the implementation of common and consistent financial controls throughout the Company. The Company's ERP system is complemented by consolidation software known as the Financial Manager's Workbench. The implementation of this software is substantially complete and is already used for contract analysis and budgeting. Timely access to data - The Company monitors the performance of each of its subsidiaries monthly, and compiles an internal report that discusses each subsidiary's operations compared to key operating metrics. Included in these metrics is a comparison to budgeted results, prior results, change in gross margin and operating income percentages, change in headcount, accounts receivable and performance measures such as days sales outstanding. The Company also maintains an evolving contract status report for work in progress ("WIP report") that details the financial data for every significant contract in progress throughout the Company. This WIP report contains the updated contract prices, cost estimates, percentage completion calculations, and calculations for the variance between revenues and billings on a job-by-job basis. The Company utilizes the Financial Manager's Workbench, a component of the firms Enterprise Resource Planning system, to conduct detailed analyses on the WIP report data and other operating metrics and presents financial reports, including a "Rack and Stack" report that lays out each subsidiary compared to its other IES peers. These reports are used by the management team to conduct financial review meetings, semi-monthly Regional Operating Officer meetings and the quarterly Home and Away meetings. Real-time response - As the Company monitors the performance of each subsidiary, certain metrics may indicate a potential for problems at a particular location. These indices include a decline in operating results or a turnover in subsidiary management. In this event, the subsidiary is placed "at watch." The subsidiary is monitored closely and, if management deems necessary, the subsidiary is placed "at risk." The "at risk" program involves bi-weekly operational and financial meetings with the subsidiary management, regional management and certain members of IES management, including the Company's Chief Operating Officer. The subsidiary's operations are closely monitored and the home office must approve any new work that is bid. Certifications The information obtained from these meetings and reports provides the Company with a strong platform to support its financial certification process. Section 302 of the Sarbanes-Oxley Act of 2002 ("SOX") requires the Company's Chief Executive Officer and Chief Financial Officer to certify the accuracy of the quarterly and annual financial statements of the Company. The purpose of the control environment and financial monitoring is to provide the Company's management with information that enables them to accurately and reliably make that certification. In this vein, each subsidiary president and controller provides a certification to IES management, and each Regional Operating Officer and Regional Controller provides a similar certification to management. These internal certifications include the scope, definitions and expectations outlined in the Sarbanes-Oxley certifications. The certification process includes a detailed positive affirmation as to the knowledge of the accuracy of presented operational results, fraud, theft and controls in place. Each certification is signed and reviewed each fiscal quarter, then presented to IES management to aid in the certification process required by SOX. These certifications are not a new control in response to the SOX. In fact, the Company has required quarterly certifications for many years and annual certifications since the inception of the firm. 26

Under section 404 of the SOX, the Company's Chief Executive Officer and Chief Financial Officer will be required to assess annually on the effectiveness and reliability of the Company's internal control environment. To comply with this regulation, the Company established a five-phased approach to defining, documenting and testing its internal control framework. The five phases include defining the Company's system of internal controls, establishing a core working group to implement the project, assessing the current state of its internal controls, filling any gaps in the framework with industry best practices, and testing the controls to ensure they are effectively working. While final rules detailing when and how certifications are to be made are not yet known, the Company is continuing to press forward with its documentation and gap analysis. Currently the Company is in phase three of its five phase project for fiscal 2003. Internal audit program IES utilizes all of its corporate resources to monitor the Company's operations. The Company has in place an internal audit program that requires each subsidiary to undergo an internal audit at least once every three years. In addition to these routine audits, internal audits may occur as a "surprise" event or if the subsidiary is placed in the "at risk" program. The internal audit reports are distributed to the subsidiary's management, the executive committee and to the Company's Audit Committee of the Board of Directors. Audit findings are addressed and a revisit is performed six months after the initial internal audit to ensure compliance. Ethics hotline IES has established a confidential toll-free hotline for the purpose of reporting known or suspected events of theft, fraud or other financial abuse. The hotline is monitored by a third party and reported to the Company. Reported incidents are communicated to the proper management to investigate. The reported incidents, results of investigations and corrective actions taken are communicated to the Company's Audit Committee. Operational policies and procedures IES has established and published operating guidelines in accordance with Generally Accepted Accounting Principles and applicable laws, as well as the Company's best practices. These guidelines encompass all aspects of operational and financial reporting, from the estimating and bidding process to the financial reporting process. The controls over the estimating and bidding procedures allow each location to select the projects for bid, but increasing levels of approval from Regional and Executive management are required based on the size and type of job before the bid can be finalized and submitted. Subsidiaries are limited by the size of job they may undertake based on their backlog and ability to manage additional growth. Subsidiaries are further restricted from undertaking non-standard work or work outside of their technical expertise. This level of management oversight and approval extends through the term of the contract once it is awarded, and is covered in the operational meetings held throughout the Company. Financial policies and procedures Financial controls are established and published in a manual provided to regional management. These financial controls include accounting policies in accordance with Generally Accepted Accounting Principles that address revenue recognition, credit 27

and cash management, financial accounting standards and business responsibilities. Adherence to these policies is verified by assertions made by each location's management, regional management, internal audit and by control checks performed at the Company's corporate headquarters. Financial controls also include requirements for processing data, storing records and segregating of duties. Monthly operating results are transmitted via a standardized model that utilizes automatic data checks to ensure the accuracy and reliability of the data presented. These checks ensure high integrity in the internal reports used by management. 28

Corporate Governance - -------------------------------------------------------------------------------- Since IES' initial public offering ("IPO") in 1998, the Company has divided the duties of Chairman of the Board and Chief Executive Officer between two individuals. As a governance policy, this prevents a concentration of control with one person. Since the IPO, Byron Snyder has served as Chairman; and since late 2001, H. Roddy Allen has served as Chief Executive Officer. The IES board has significant representation from independent directors. The Board of Directors consists of 7 directors of which four are independent directors. The inside board members include H. Roddy Allen, the President and Chief Executive Officer, Rick China, the Chief Operating Officer and Byron Snyder, the Chairman of the Board and founder of IES. This stands in contrast to the original board in 1998, consisting of 11 members, many of whom were among the sixteen owners of the founding companies. The Board has four committees: Audit, Compensation, Nominating/Governance and Executive. The Audit, Compensation, and Nominating/Governance committees are entirely composed of independent directors. During fiscal 2002, IES implemented an evaluation process in which those reporting directly to the CEO and the Board of Directors review the CEO anonymously and rate him on key business and management strengths. These ratings are reviewed by the board and serve as an early warning system for any potential problems that might arise. IES also maintains a growing internal audit function, an important consideration for a Company that has grown through acquisition and has numerous subsidiaries across the country. Currently every subsidiary (about 60, given that some of the acquisitions have been merged with other subsidiaries) undergoes an internal audit at least once every three years with approximately 20 internal audits performed each year. 31

Industry Overview - -------------------------------------------------------------------------------- The electrical and low voltage contracting industry is highly fragmented, with over 70,000 electrical contractors operating across the United States in 2001. Most are small, private "mom and pop" operations. Three quarters of these companies have less than 10 employees, according to the U.S. Department of Commerce. Only a little over 1% have more than 100 employees and just a handful, like IES, have thousands of workers and the advantages of significant scale. IES has approximately 13,000 employees. Below is a table that shows the breakdown of the size of electrical contractors based on number of employees. It clearly demonstrates the significant fragmentation of the industry. Interestingly some of IES' largest competitors in each individual local market are companies with 20 to 100 employees. EXHIBIT 19 ELECTRICAL CONTRACTORS SEGMENTED BY NUMBER OF EMPLOYEES - ---------------------------------------------------- # of Employees Percent of Electrical Contractors - ---------------------------------------------------- 1 to 4 57.0% 5 to 9 19.4% 10 to 19 12.3% 20 to 49 7.7% 50 to 99 2.2% 100 or more 1.4% ------ 100.0% - ---------------------------------------------------- Source: Electrical Contractor Magazine At the end of 2001, the electrical contracting market was estimated at $95 billion. As the largest electrical contractor with $1.5 billion in revenues, IES still only represents 1.6% of the market (see Exhibit 20 below).

Virtually all construction and renovation work in the U.S. requires electrical contracting services. Electrical and low voltage work usually runs between 8%-12% of the cost of a commercial or industrial project and 5%-10% of the cost of a residential project. This percentage is substantially higher in high-end residential home building. Growth in the electrical contracting market has accelerated in recent years due to: o Complexity as a result of the increase in computer, security and communications systems in the workplace. Computers, printers and on-line access are a part of virtually every workstation, increasing the electrical and low voltage demands placed on a given system. New telecommunications systems have also increased the burden, as well as networking of local and wide area computer systems. o The pace of electrical renovation of existing structures has increased, primarily as a result of more advanced computer and communications systems. o There has been an increased focus on cost savings through energy management systems. o New electrical codes for power efficiency and safety. o National energy standards have been revised stressing energy-efficient lighting fixtures and other equipment. o As the workplace has become more complex and more dependent on technology, there has been an increased demand for backup power systems. o Increased security requirements have also increased demand and sophistication of security systems. o Increased demand for preventive maintenance to minimize disruption of power. The electrical contracting industry had a difficult year in 2002 due to the reduction in commercial and industrial construction spending. Commercial and industrial construction, which accounts for about 80% of revenues for IES, was down 18% according to figures from F.W. Dodge. The strong demand in the late 1990's and in early 2000 increased the supply of providers, which made the decreases in 2002 and 2003 particularly difficult due to the excess supply of electrical service providers. However, the growth drivers for the industry detailed above are long-term in nature and will continue to generate demand for electrical contracting services throughout the next several decades. Residential construction, driven by record low mortgage rates, drove spending on single family housing construction up an estimated 15% in 2002 according to F.W. Dodge. The low rates are so appealing that many people who would typically be apartment dwellers are becoming first-time homeowners instead. This is causing the single family home and condominium market to remain quite strong in 2003, but it is beginning to cause some slowdown in multifamily construction. Specialty Contractors IES is currently the only "pure play" publicly traded electrical contractor in operation. Specialty contractor competitors provide other services besides electrical contracting such as mechanical contracting and building maintenance as well as other services. Below is an overview of some of the publicly traded specialty contractors. The only specialty contractors listed below that IES typically competes directly against are EMCOR and 33

Quanta Services. However, EMCOR's primarily union affiliation tends to keep their focus in the northern cities and areas with a high level of union affiliation where IES has less of a presence and Quanta Services primarily services the power utility sector and this type of work is less than 10% of IES' revenues while it represents over 50% of Quanta's revenues. Information below is from public filings of each company and is included herein as summary. Further information on these companies may be obtained from those filings. EMCOR- operates internationally with locations in the United States, Canada, Europe, the Middle East and Far East and South Africa. Through over 75 operating companies, EMCOR employs 28,000 workers and generated almost $4 billion in revenues in 2002. The company divides its business into three segments; (1) mechanical construction (2) electrical construction and (3) facilities management. Facilities services make up about 17% of revenues and the rest are approximately equally divided between electrical and mechanical work. EMCOR's work tends to be concentrated in larger cities due to its union affiliation. This has allowed the company to win public transportation work to buffer it during the economic slowdown. Quanta Services- Quanta is a leading provider of specialized contracting services, with a focus on the electric power, telecommunications, broadband cable and gas pipeline industries. The company provides a range of services, including the design, installation, maintenance and repair of many types of network infrastructure. Quanta has offices in 40 states, and operations in all 50 states, as well as Canada. Revenues in 2002 were approximately $1.75 billion with 53% from electric and gas utility, 16% from telecom, 12% from cable television and 19% from other. Comfort Systems- The company focuses almost exclusively on the heating, ventilation and air conditioning market (known as HVAC) and is a leading provider of these services, and had 2002 revenues of $820 million. In 2002, the company sold 19 union affiliated subsidiaries representing about $650 million in revenues to EMCOR. Comfort Systems now has 84 locations in 57 cities throughout the US. Dycom- is headquartered in Palm Beach Gardens, Florida and is one of the larger telecommunications services companies. The company has 28 operating subsidiaries. Dycom currently serves over 100 different customers in 48 states, with approximately 5,700 employees, based out of more than 200 locations throughout the United States. Revenues for fiscal year 2002 exceeded $600 million. In 2002, Dycom acquired Arguss, a provider of infrastructure services to cable and telecommunications companies, for about $85 million, expanding its geographical footprint within its existing customer base. For the six months ended January 2003 the revenue breakdown was 88.3% telecommunications services, 9.1% underground utility locating and 2.6% construction and maintenance to electrical utilities. Below is a chart that illustrates how IES' revenue and focus differs from some of its closer publicly traded peers. Notice that IES' is the only publicly- traded pure play electrical contractor in the group. In addition, IES is the only publicly-traded completely merit shop electrical contractor, giving it significantly more flexibility to utilize prefabrication and pre-assembly on projects which saves money and time. 34

Competitors Typically, IES bids against a larger national competitor like EMCOR or one of the larger private players such as Rosendin or Fisk on national projects or large regional projects such as an airport. In addition to publicly traded peers, IES competes against private regional players that range from $40 million to over $300 million in revenues, as well as smaller local competitors the can range anywhere from $2 million to $30 million in revenues. There are 10 private electrical contractors with revenues between $200 million and $600 million. Of those players, approximately seven are companies IES competes against and, even then, it is only occasionally and in selected markets. There are another 100 or so companies in the $40 million to $200 million range and of those companies IES competes against approximately 40 in local and regional markets as well as in certain segments such as utilities or multifamily residential. On larger single site projects, IES is likely to bid against large regional or local players with access to bonding and capital such as Fisk (owned by Tyco), Red Simpson or Infrasource, to name a few. However, on smaller projects that make up the greatest percentage of IES' revenues, the Company's largest competitors are often smaller private electrical contractors that have anywhere from $2 million to $30 million in revenue. These smaller players are actually the organizations IES bids against most frequently in each local market. To provide more insight into the competitive landscape, the next few pages contain a review of the larger private electrical contractors over $200 million, as well larger players that IES competes against. Included in the description are the areas where IES competes against these companies. Surprisingly, as can be seen from the data, many of the larger regional players rarely compete with IES for work. This is most likely the result of the geographic markets served. Larger Private Electrical Contractors and Major IES Competitors MYR Group is the largest private electrical contractor, with 2001 revenues of about $627 million and subsidiaries in 19 states. The company is headquartered in Illinois and provides a complete range of power line and electrical services for electric utilities, telecommunications providers, commercial and industrial facilities and government 35

Outlook and Valuation - -------------------------------------------------------------------------------- After years of economic expansion, the economy stumbled in 2002 and the beginning of 2003. The events of September 11th have demonstrated that unpredictable events can have a significant impact on the economy and on equity valuations. Below is an analysis of F.W. Dodge's outlook for construction spending by sector in 2003 through 2005. Although 2003 is expected to remain soft, 2004 and 2005 are projected to be much stronger in commercial and industrial spending according to F. W. Dodge with particular strength in markets where IES has expertise and a history of earning higher profits, which include office buildings, retail centers, hotels and manufacturing facilities. Residential construction spending is expected to remain quite strong with only a 1% decrease in 2003 and the multi-family construction outlook for 2004 is quite strong with 12% expected growth. Market Outlook Below is an analysis of F.W. Dodge's expectations for 2003 through 2005, as well as some analysis on profitability trends through cycles in the construction industry. This analysis should help investors to develop projections for IES' performance over the next few years. F.W. Dodge anticipates that construction spending will slide very slightly, about 2%, in fiscal 2003, as single-family housing construction takes a well-deserved rest after a record few years with a 1% decrease. Total non-building construction is projected to decline 7% in fiscal 2003 and overall non-residential building construction is projected to be down 2%. There are several factors impacting construction this year. With declining incomes and tax dollars, states and the federal government have seen projected budget surpluses quickly turn to deficits and public works and institutional building projects are expected to slow this year. Additionally, while interest rates are now low and have recently come down, F.W. Dodge believes some upward movement is possible before the end of 2003 that will cause single-family housing starts to flatten out. As for commercial and industrial, a weak employment market may dampen demand for new projects. Both 2004 and 2005 are projected to be strong years for construction spending with an overall growth rate of 4% in 2004 and 4% in 2005. Double-digit growth is expected in the commercial and industrial construction markets where the majority of IES' revenue is generated.

Dodge report and IES company data. Based on December 31, year end. (2) Market data includes electrical services provided for communications infrastructure which is why this market is in such a state of decline. Comparison of Historical Profitability Performance versus Construction Spending The industry is highly cyclical and driven to a large extent by construction expenditures. Growth in construction expenditures can vary widely from year to year and this will have a flow-through impact on profitability of electrical, mechanical and other contractors. Below is an analysis of 30 years of construction expenditures compared to the EBITDA margins of Fluor Corp. (Fluor has a long history of data and serves as a good proxy for the industry). IES believes the analysis demonstrates that in periods of growth, overall profitability and profit margins expand, and when construction spending contracts, profit margins contract as well. Construction spending, the primary business driver for IES and its competitors, is highly variable and can significantly impact profitability. 40

Dodge Construction Industry Data. Exhibit 25 below illustrates IES and its peers' gross profit margin and operating income margin over the past four years. With the exception of EMCOR, which generates over 20% of its revenues from facilities maintenance, which is not tied to construction, the profit margins have contracted as commercial and industrial construction spending has declined.

Dodge forecasts are correct, it is possible that IES could see a 150 to 300 basis point improvement in operating income margin over the course of 2004 and 2005. IES' Weighted Average Cost of Capital ("WACC") IES believes its cost of capital, based on a WACC analysis, is between 10% and 12%. WACC is the combination of IES' cost of debt, which is approximately 6% after tax, and its cost of equity, which is between 15% and 16%. The calculation is based on using the average beta for the specialty contracting industry adjusted for the appropriate capital structure, a risk free rate of 3.75%, which is the recent 10-year government bond rate, and a target debt to capital ratio for IES of between 35% and 45%. The WACC analysis also includes a 3.1% size premium for cost of equity given that IES is a small cap stock. 41

IES relative to its Peers IES is the largest electrical contractor, however there are a number of companies in similar market segments that are good proxies for valuation. IES' publicly traded peers include EMCOR, Comfort Systems, Quanta Services and Dycom. An analysis of select engineering and construction firms including Fluor, Shaw Group and Jacobs Engineering has also been included because, although these firms have a slightly different business model, they operate in the same markets as IES and face a similar market environment.

Appendix I - Construction Accounting Primer - -------------------------------------------------------------------------------- As an electrical contractor, IES uses construction accounting conventions as prescribed under GAAP accounting. The primary issue surrounding construction accounting is recognition of revenue from longer-term construction contracts. With longer-term fixed-price contracts, contractors generally use the percentage of completion method of accounting. This method requires companies to estimate the percentage of a project that it has completed work on. There are several acceptable methods for determining percentage of completion such as: the ratio of costs incurred to date to the total expected costs at completion, the ratio of labor hours or dollars incurred to date to the total expected labor hours or dollars at completion, or any other rationale and systematic method. IES uses the ratio of costs incurred to date to the total expected costs at completion to estimate percentage of completion. Generally, if 40% of a project's cost has been incurred over a 6 month period then the company should recognize 40% of the revenues and 40% of the profits related to the project. The primary issue in percentage of completion accounting is the use of estimates for total costs at completion. If estimates change during a project, the impact of the change in profitability is recognized in the period in which the estimate is changed. The following example illustrates how changes in estimates can impact the profitability across periods. Example: * Fixed price contract to be completed over 2 accounting periods. * Total contract amount equals $1 million. * Cost of project to contractor is $850,000 for a 15% margin at completion. COMPANY ESTIMATES ARE CORRECT THROUGHOUT PROJECT PERIOD 1 PERIOD 2 TOTAL -------- -------- ----------- Revenue $500,000 $500,000 $ 1,000,000 Cost of Goods Sold 425,000 425,000 850,000 -------- -------- ----------- Gross Profit $ 75,000 $ 75,000 $ 150,000 Gross Margin 15.0% 15.0% 15.0% THE PROJECT IS COMPLETED AT A HIGHER PROFIT THAN ORIGINALLY ESTIMATED PERIOD 1 PERIOD 2 TOTAL -------- -------- ----------- Revenue $500,000 $500,000 $ 1,000,000 Cost of Goods Sold 425,000 400,000 825,000 -------- -------- ----------- Gross Profit $ 75,000 $100,000 $ 175,000 Gross Margin 15.0% 20.0% 17.5% In the second example above, the original profit estimates are significantly understated. In period two, the profitability on the project rises as profits "catch up" to reflect a 17.5% margin over the life of the contract. For companies with long projects that last for 2 to 3 years, the risk of under- or overstating revenues and profitability for several quarters exists, but for companies with an average project life of 2 to 3 months, this risk is substantially reduced. The average project life at IES is only 6 to 8 months so any inaccuracies in estimates are corrected fairly quickly. Additionally, because of IES' size and large number of projects, under- and overestimates across the Company will tend to offset each other. 47

Under percentage of completion accounting, contract revenue is based on costs incurred while customer billings may be impacted by other factors such as: achieving certain milestones, acceptance of completed work by the customer or some other schedule. Because of this discrepancy, contract revenue recognized is usually different from the amount billed as the project progresses. When revenue recognized exceeds customer billings the excess is reported as a current asset referred to as "costs and estimated earnings in excess of billings on uncompleted contracts". Sometimes it may be referred to as "underbillings" or "unbilled receivables" although these are not GAAP terms. Conversely, when customer billings exceed contract revenue recognized, the excess is reported as a current liability referred to as "billings in excess of costs and estimated earnings on uncompleted contracts". Sometimes it may be referred to as "overbillings" although this is not a GAAP term. When calculating days sales outstanding underbillings should be added to accounts receivable and overbillings should be subtracted from accounts receivable. The other balance sheet term that sometimes causes confusion is retainage. It is a current asset on the balance sheet that is a subcategory of accounts receivable. Often some portion of payment is held at the completion of a contract for some period of time almost like a warranty. The amount of retainage on a project is determined upfront when the terms of the contract are negotiated and is typically 5% to 10% of the overall revenue on the project. 48 ________________________________________________________________________________ NYSE: IES (C)2003 Integrated Electrical Services, Inc.
