Quanta Services, Inc.
(NYSE: PWR)

The Power of One

Leading Provider of Specialty Contracting Services

Overview & Key Points

As one of the largest specialty infrastructure contractors in the U.S., Quanta is well positioned to capitalize on: the urgent need for the nations power grid to be expanded, upgraded and maintained, on new telecommunications initiatives and also on increasing infrastructure outsourcing trends.

Demand for electricity is expected to increase by more than 20%¹ over the next decade and utilities have made less than adequate investment in the nations power grid during the past few years. Quanta estimates that it will cost $100 billion to $200 billion over the next 10 to 15 years to expand, upgrade and maintain the nations power grid to meet current and future electricity demand.

A comprehensive energy bill was signed by the President in August 2005, which, among other things, is aimed at improving the nations electric transmission capacity, reliability and promoting investment in the nations energy infrastructure. Signage of the bill may not yield an immediate positive impact on Quantas business, but the positive impact of more active infrastructure investment by utilities should begin in the next twelve to eighteen months.

Quanta saw increased activity in the telecommunications industry in the second half of 2004 and year-to-date in 2005 that reinforces its belief that spending is returning to certain pockets of the telecommunications industry particularly from fiber to the premise (FTTP) and fiber to the node (FTTN) initiatives.

Company Profile				December 2005

This document is being published by Quanta Services in continuation of the Companys goal to provide more disclosure and transparency to the investment community regarding Quantas operations, strategies, industry dynamics and conditions, etc. Quanta Services intends to take greater responsibility for and a proactive role in communicating with the investment community and in providing greater operating and financial transparency.

Executive Summary & Selected Highlights

Founded in August 1997, with its IPO in February 1998, Quanta Services is a leading national provider of specialty contracting solutions to the electric power, natural gas, telecommunications, cable television and other industries. Quanta was created to respond to the increasing need for the outsourcing of infrastructure services. That is, Quantas current and future customers are expecting as they grow their businesses through mergers and increased outsourcing specialty contractors to increase the scope of their service capabilities and geographic reach. Through its operating units located throughout the U.S., Quanta provides design, installation, repair, maintenance and emergency response services that enable its customers to reduce costs, increase operating efficiencies and improve network performance.

The August 2003 power blackout, the largest in North Americas history, brought to the forefront what the power industry has known for years: the nations power grid is old, overloaded, and needs significant upgrades and maintenance to serve the countrys current and future power needs. Quanta estimates that it will cost between $100 billion and $200 billion to upgrade and maintain the countrys transmission and distribution (T&D) system adequately over the next ten to fifteen years. According to Platts, a leading energy news, research and consulting company, before the August 2003 blackout there were $27.5 billion worth of T&D projects to begin in 2004 and be completed by 2008. The discrepancy between the $27.5 billion earmarked before the blackout versus the $100 billion the Electric Power Research Industry estimates it would cost to fix the system illustrates the magnitude of the underinvestment by the electric utility industry in its T&D infrastructure over the years.

Quanta and the industries it serves are emerging from the most difficult operating conditions in thirty years due to challenging economic and capital markets conditions and the collapse of the telecommunications industry. However, Quantas customers have been regaining financial strength and are experiencing operational stability such that their spending patterns have been improving. It may be some time before normal operating conditions return, but the Company is cautiously optimistic that its operating environment is headed in the right direction. As operating conditions return to normal and growth opportunities return, there are several major trends that could generate long-term organic revenue growth opportunities of approximately 15% annually:

New awareness of transmission and distribution network upgrade needs and new telecommunications network upgrade initiatives

Customers focusing on their core business, which increases the value of Quantas end-to-end services

Increased outsourcing of infrastructure services

Faced with extremely difficult operating conditions for the last three years, Quanta has focused on its operations and on maintaining a healthy financial position. Quanta has seen all of its end-markets experience increased stability over the past several quarters. As Quantas customers financial health has improved, these customers are beginning to increase investment in their infrastructure networks. Quanta expects to achieve increases in profitability through the course of the year so long as industry conditions remain stable. With $223.6 million of cash on its balance sheet as of September 30, 2005, Quanta believes it is well positioned, both financially and operationally, to successfully operate in the current environment and to capitalize on future growth opportunities.

Company Profile				December 2005

Quanta Services Company Overview

Founded in August 1997, with its IPO in February 1998, Quanta Services is a leading national provider of specialty contracting solutions to the electric power, natural gas, telecommunications, cable television, and specialty services industries. Through its operating units located throughout the U.S., Quanta provides design, installation, repair, maintenance and emergency response services that enable Quantas customers to reduce costs, increase operating efficiencies and improve network performance. The Company also provides a variety of specialty services such as inside electrical wiring; intelligent traffic networks; cable and control systems for light rail lines, airports and highways; and specialty rock trenching, directional boring and road milling for industrial and commercial customers.

Quanta was created to respond to the increasing need for outsourced infrastructure services. Quantas customers are expecting specialty contractors to increase the scope of their service capabilities and geographic reach as they grow their businesses through mergers and increased outsourcing. Such requirements are a tall order for the average private specialty contractor, so in February 1998, Quanta went public to obtain additional capital to pursue a strategy of smart growth consolidation coupled with organic growth, driven by the growth in infrastructure services outsourcing trends and increased customer demands.

After its IPO, Quanta selectively acquired approximately 85 specialty contractors over several years to increase the scope of its services, expand its geographic reach and diversity, and enhance its future growth opportunities. Though initially focused on the electric utility industry, Quanta expanded into the telecommunications and cable television infrastructure services industries as its core utility customers began expanding into those unregulated sectors and turned to Quanta to perform simultaneous electrical, telecommunications and cable television related projects.

With the challenges in the telecommunications and cable television sectors, Quantas utility customers largely have ceased pursuing telecommunications and cable television initiatives and have refocused on the electric and gas utility side of their businesses. To meet the ever-changing needs of its core customers, Quanta has reorganized its operations to focus on two primary client bases: Electric Power/Natural Gas and Telecommunications/Cable Television.

Increased Outsourcing of Infrastructure Services

Heightened Awareness of Network Upgrade Needs

Due to challenging operating and capital market conditions and the collapse of the telecommunications industry, many service providers in the industries Quanta serves have not adequately invested in their networks. This has been a problem in the electric utility industry for many years, which was highlighted during the August 2003 power blackout. The collapse of the telecommunications industry resulted in nearly all telecommunications companies significantly reducing network maintenance and expansion plans for several years. This has created pent-up demand for general network maintenance as well as for new network development to handle demand and competition for new communications and entertainment services.

August 2003 Blackout Highlighted Need for Transmission & Distribution (T&D) Network Upgrade & Maintenance

For many years the electric power industry has not invested enough in its T&D networks to keep pace with electricity demand. Though a while back, the August 14, 2003 power blackout the largest power blackout in North Americas history highlighted the significant need for T&D network upgrade and maintenance. The statistics regarding the impact of the blackout are staggering:

		Eight states and one Canadian province, home to approximately 50 million people, were affected.

		Twenty-two U.S. and Canadian nuclear plants were shut down.

		Ten major airports were shut down, canceling 700 flights nationwide.

		The Cleveland National Guard distributed 7,600 gallons of drinking water after the citys four main pumping stations failed.

		Approximately 350,000 people were on New York City subways when the power went out; 19 trains were in underwater tunnels.

		*Various estimates put the cost of the outage between $6 billion and $8 billion.*

Due to the number of people impacted by the catastrophic failure of the countrys power grid, the event increased the nations awareness of what has been known in the power industry for many years: the nations electrical grid is old, overloaded, and needs significant maintenance and expansion to handle the countrys current and growing power needs. Despite previous power blackouts since the 1960s that left tens of millions of people in the dark, expansion and maintenance of the grid has fallen short. As the countrys population has grown and technology has become a larger part of everyday life, generating

capacity has increased nearly eight fold over the past ten years² while demand for electricity has grown over 20%³. However, transmission capacity over the last ten years has fallen by approximately 16% and is expected to decline by approximately 7% from 2003 to 2008⁴.

The August 2003 blackout caught the attention of the media, the general population, the politicians, and the electric utility industry, and discussions are ongoing to find solutions to remedy the problem. For example, the Electric Power Research Institute began a public education campaign to raise some $100 billion from investors, governments and consumers to upgrade the nations power grid.

The August 2003 blackout was the worst in the nations history, but it was not the first major blackout impacting North America, and unfortunately, may not be the last. The accompanying table lists examples of other major bulk electric system power outages that have hit North America. Note that this list excludes many past power outage events that also impacted many people, such as the rolling blackouts experienced in California during 2000 and 2001.

Each year there are smaller power outages that occur throughout North America that do not get significant media attention, but are more frequent than one would expect. The dots in the chart to the right represent individual outages in North America between 1984 and 1997. Though the data is a bit dated, it remains an accurate illustration and the number of system outages per year and the number of customers impacted has probably increased since 1997 due to lack of T&D investment.

Company Profile				December 2005

Telecommunications Network Maintenance & Upgrade Needs

The collapse of the telecommunications industry from 2001 to 2003 was the most severe shock to the industry in its history many telecommunications companies filed for bankruptcy protection or shut down. Surviving companies significantly reduced capital expenditures and network investment to focus on cash generation and debt reduction. As a result, telecommunications networks have not been properly maintained over the last few years and network expansion has been minimal.

Telecommunications industry spending stabilized in 2004 and in the latter half of 2004 several significant new telecommunications initiatives were announced that require significant network expansion and upgrades. These new initiatives involve bringing fiber optic cable much closer to the end user: fiber to the premise (FTTP) and fiber to the node (FTTN). Such initiatives have been announced and are being implemented by Verizon and SBC Communications and municipalities have also become active in FTTx initiatives. These projects will increase telecommunications network spending by billions of dollars over the next five to ten years and should create favorable demand for the network installation and maintenance services Quanta provides.

Customers Focusing on Core Business; Value of End-to-End Solutions

All of the industries Quanta serves are facing very competitive environments. With challenging economic and capital market conditions over the last few years, many companies in the electric and gas utility, telecommunications, and cable television industries have refocused their human and financial assets on core operations, operating efficiencies and prudent capital investment in their networks. The absolute dollar amount of network capital expenditures by Quantas customers has declined over the past few years. However, conditions generally have stabilized and Quantas customers will need to begin investing in the development and maintenance of their networks once again.

One way for Quantas customers to focus on core operations, operating efficiencies and prudent capital investment is to outsource non-revenue-generating functions, such as network infrastructure development and maintenance. Small owner-operated contractors are not as well positioned as Quanta to serve the broad range of needs that many utilities, telecommunications, and cable television companies request. Further, service providers are reducing the number of vendors they deal with to reduce paperwork, bidding and vendor management costs, and time. Increasingly, the industries Quanta serves are looking for companies like Quanta that are able to provide a wide array of network infrastructure services on a national basis on time and on budget.

Increased Outsourcing of Infrastructure Services

Challenging economic and capital market conditions, stiff competition amongst their peers, focus on efficiencies, and the need to enhance and maintain the lifeblood of their business their networks are causing companies in the electric and gas utility, telecommunications, and cable television industries to increase the amount of network infrastructure work they outsource to specialty contractors like Quanta Services.

Quanta estimates that annual infrastructure spending in the primary industries Quanta serves is approximately $30 $40 billion. Quanta further estimates that the electric power industry typically outsources approximately 30%-40% of its infrastructure work to specialty contractors, telecommunications typically outsources approximately 50%-60% of its infrastructure work, and cable television typically outsources approximately 70%-80% of its infrastructure work to specialty contractors.

Company Profile				December 2005

As economic, capital market, and operating conditions improve for Quantas customers and they return to more normalized levels of investment in their networks, Quantas annual addressable market opportunity and the amount of work that is outsourced should grow.

In addition to service providers outsourcing elements of their network installation and maintenance activities, Quanta believes there is significant opportunity in its customers completely outsourcing the operation and maintenance of their network infrastructure (utilities, telecommunications and cable television companies alike). In fact, Quanta is the only specialty contractor to successfully develop and implement a complete infrastructure outsourcing program with an electric utility.

Puget Sound Energy was one of the first utilities to announce that it would progressively outsource 100% of its infrastructure operations and maintenance functions. Puget Sound Energy considered twelve different companies for this vital task and chose Quanta for both electric and gas infrastructure outsourcing initiatives. Today, Quanta is managing all electric and gas construction for new residences and businesses in Puget Sounds Washington service area, as well as managing all related inventory and materials. Productive work hours have increased by at least one hour per day, a 30% cost savings over historical numbers is projected, and service levels continue to improve. Puget Sound Energy and Quanta forged new ground with this outsourcing model and in 4Q04 Quanta negotiated a two-year extension to its outsourcing agreement with Puget Sound Energy. As it has proven successful, more and more companies are seriously examining a complete outsourcing model.

Massive Need for Transmission & Distribution Upgrades & Maintenance

Source: Platts Research

The challenge the industry faces is not one of a shortage of electricity and generating capacity, but capacity strains and bottlenecks for transmitting and distributing the electricity to the end user. The map above depicts the nations major transmission lines and identifies key capacity constraints. As indicated, there are a troubling number of key transmission capacity constraints. While demand for electricity has grown over 20% over the past decade, transmission capacity has fallen by approximately 16% and is expected to decline further by approximately 7% from 2003 to 2008.

Quanta estimates that it will cost between $100 billion and $200 billion to significantly upgrade and

maintain the countrys transmission and distribution (T&D) system over the next ten to fifteen years.

According to Platts, before the August 2003 blackout there was $27.5 billion worth of T&D projects to begin in 2004 and be completed by 2008. The discrepancy between the amount of earmarked projects before the blackout versus the $100 billion investment the power industry is now trying to attract illustrates the magnitude of the electric power industrys underinvestment in its T&D infrastructure over the years.

Prior to the August 2003 blackout, R.J. Rudden Associates estimated that bringing spending in line with forecast demand would require a 25% annual increase in transmission spending and a 50% annual increase in distribution spending.

The majority of the nations T&D infrastructure was built shortly after World War II, is over 50 years old in many cases, and is beyond its useful life. The table below illustrates the number of poles installed annually by a particular electric power utility. While the identity of the specific utility will remain concealed, the chart illustrates an investment pattern that is typical for the average US electric utility. The vast majority of the grid system was installed from 1945 to the late 1970s. With these assets already past or rapidly approaching the end of their useful life, as depicted in the chart below, there is significant demand for pole repair and replacement going forward based on past T&D investment.

Electric utilities have underinvested in their T&D infrastructure for three primary reasons: (1) uncertainty regarding the final terms of the Federal Energy Regulatory Commissions (FERC) standard market design proposal, (2) the inability to recover investment costs in T&D investment under state imposed rate freezes, and (3) balance sheet issues resulting from energy trading losses, telecommunications business investments, etc. Note that many of the state rate freezes began to expire in 2003 and pressure will mount on utilities to invest in their T&D infrastructure.

Company Profile				December 2005

It is troubling that investment in T&D infrastructure has declined over the years while demand for electricity has meaningfully increased. Coupled with the fact that much of the nations T&D infrastructure is 50 years old, it is apparent that the power industry is increasingly relying on aging assets. This is a recipe for significant future problems as power demand increases on an aged and overloaded grid.

The accompanying table depicts adjusted historical utility T&D expenditures to year 2000 dollars and assumes that T&D assets have a 40 year useful life. The data suggests (1) capital spending has not been enough to replace old transmission assets and (2) distribution has not earmarked enough spending to replace aging distribution assets in the future.

As the charts and data show, utility investment in the expansion and maintenance of T&D assets has lagged what is needed. Further, there is significant pending demand for the replacement and repair of poles that were installed 50 years ago.

Expanding and improving current T&D assets to meet current and future power demand is a daunting task. Further complicating the issue, the demand for electricity is expected to continue to grow at a healthy rate for the next few decades as (1) the countrys population expands and (2) we become increasingly dependent on technology, which requires power.

Source: PA Consulting based on datafrom the UDI database

The map below illustrates the estimated demand for electricity by state in the US from 2003 to 2014. It is estimated that overall electricity demand in the US will grow in excess of 20% over this period. Areas such as California and the northeastern US are expected to have 40%-55% increases in electricity demand over the period; note both are areas that have had major blackouts and brownouts in the past few years.

The electric utility industry finds itself in the position of playing catch-up from underinvestment, needing to replace and repair a significant amount of its legacy distribution network, and properly plan for future electricity demand. While the August 2003 blackout has caught the attention of utilities and politicians, it is too early to determine if it will result in real efforts to fix the grid. To the extent that this wake up call is heeded, it may take twelve months or more before hurdles are crossed and serious T&D investment begins. However, as one of the largest specialty electrical infrastructure contractor in the country, Quanta is well positioned to meet the needs of its customers and to harvest the fruits of future increases in T&D network investment by the electric utility industry.

Quanta Services Operations Overview

For the first nine months of 2005, revenues generated by customers in the electric power and natural gas industries accounted for approximately 68% of revenue, telecommunications and cable television for approximately 15% and ancillary for approximately 17%. For the year 2004, revenues generated by customers in the electric power and natural gas industries accounted for approximately 65% of revenue, telecommunications and cable television for approximately 17% and ancillary for approximately 18%. For the year 2003, revenues generated by customers in the electric power and natural gas industries accounted for approximately 60% of revenue, telecommunications and cable television for approximately 22% and ancillary for approximately 18%.

Quanta estimates that the combined historical average market opportunity for infrastructure spending is approximately $30 $40 billion annually. Of that, Quanta estimates that the six largest public and private specialty contractors serving these combined industries only account for 15% or less of the market. Quanta estimates that it commands the largest portion of this estimated 15% share, but that it is less than 5% of the total addressable market. The balance of the market is served by smaller, typically private companies. With its greater scope of services, greater financial and organizational resources, and superior work force, Quanta believes it has significant opportunities to increase its market share over time. Quanta estimates that approximately 30%-40% of electric and gas infrastructure work is typically outsourced, 50%-60% of telecommunications infrastructure work is outsourced, and 70%-80% of cable television infrastructure work is outsourced currently.

As the accompanying charts depict, the percentage of revenues Quanta derived from the telecommunications and cable television industries in 2004 declined versus the year 2001. This is primarily due to the historic collapse of the telecommunications market and a challenging operating environment in the cable television market. As a result, nearly all of Quantas telecommunications and cable television customers experienced operating and financial challenges for several years, and a number of Quantas telecommunications and cable television customers have filed for bankruptcy. As a result, capital expenditures and overall network investment by the telecommunications and cable television sectors have declined significantly versus levels in the late 1990s and early 2000, and also relative to normal historical levels.

Company Profile				December 2005

Quanta believes the historic downturn of the telecommunications industry has passed and that the industry has stabilized. Further, there is several telecommunications initiatives currently in discussion and underway by several government organizations, wire line carriers and wireless carriers that could provide Quanta with pockets of opportunity for its telecommunications group in the future. However, Quanta currently does not believe these opportunities are indicative of an overall return to historical network investment levels by the telecommunications industry as a whole.

With the stabilization of several of Quantas markets, the Company has begun to see gross margins generally stabilize as well. While operating conditions are still abnormal and many challenges remain, Quanta is also beginning to see some opportunity for margins to improve slightly, but they are not expected to return to historical levels in the near term. To the extent that Quantas primary markets remain stable or begin to improve, margins could gradually continue to improve.

Quanta is unique from its competitors because it has always had a diversified network infrastructure service offering for its customers and a diversified customer base. Thus, Quanta is not overly reliant on a given industry or client for business. For 3Q05, Quantas largest customer accounted for 5% of revenues. For 3Q05, Quantas top ten and top twenty customers accounted for approximately 36% and 49% of revenues, respectively. This diverse customer base reduces Quantas reliance on any one customer in a given period and is one reason why the Company was able to remain financially healthy through the tumultuous telecommunications downturn over the past few years.

Company Profile				December 2005

It is important to understand that Quantas business is typically influenced by seasonal factors. These factors include influences due to weather, capital expenditure spending patterns, bidding seasons, and holidays. Typically, Quantas revenues are lowest in the first quarter of the year because cold, snowy or wet conditions cause delays. The second quarter is typically better than the first, as some projects begin, but continued cold and wet weather can often impact second quarter productivity. The third quarter is typically the best of the year, as a greater number of projects are underway and weather is more accommodating to work on projects. Revenues during the fourth quarter of the year are typically lower than the third quarter but higher than the second quarter. Many projects are completed in the fourth quarter and revenues often are positively impacted by customers seeking to spend their capital budget before the end of the year; however, the holiday season and inclement weather sometimes can cause delays.

Electric Utility Infrastructure Services

Quanta performs a complete range of specialty contracting installation, maintenance and repair services for the electric utility industry. Types of electric utility customers include investor-owned utilities (IOUs), independent power producers (IPPs), rural electric associations (REAs) and federal, state and municipal agencies.

As the largest specialty electric power contractor in the US, Quanta has some of the most experienced contractors and employees in the industry. In fact, many of the companies that are now part of Quanta contributed to the original build-out of the national transmission and distribution system over 70 years ago.

Quanta has the ability to handle any electrical infrastructure need for its customers. From project-based engineering and construction of a multi-state, several hundred mile, high voltage transmission line and substation system to complex underground distribution networks, Quanta can handle every size and scope of power project. In fact, there are more than 200,000 miles of overhead electrical lines and thousands of miles of underground electrical cable that have been built and/or are maintained by Quanta Services.

Energized Services

One of Quantas significant competitive advantages on the power side is its unmatched expertise and capabilities in the field of energized services. Quantas Energized Services and techniques enable Quanta to perform a wide variety of installation, maintenance, rebuild and repair services to almost all parts of an electric network while the network remains energized, without service interruption. Unique to Quantas specialty electrical service offering is its exclusive, patented LineMaster^TM Robotic Arm. Quanta owns the US rights and the exclusive right to use the LineMaster Robotic Arm for more than the next 10 years. The LineMaster Robotic Arm is used in the construction, maintenance, repair, and improvement of energized T&D lines and substation facilities, and can reduce project completion times by more than 50% versus traditional methods. The telescoping robotic arm temporarily supports live power lines to allow repair or replacement of transmission poles, cross-arms, insulators, etc., while maintaining an energized connection. Importantly, this capability prevents Quantas customers from having to shut down a portion of the power grid to allow work to be done, eliminating downtime costs and angry consumers.

Hotstick & Barehand Hotstick and barehand techniques also enable crews to work on lines without interrupting the customers power supply. Quanta uses hotsticks to move conductors, install fuses, and open and close switches. For more intricate repairs, Quantas crews use barehand techniques in which live-line workers wear specially designed protective gear that enables them to work at the same electrical potential as the line. Quantas employees performing energized services are hand-selected, experienced journeymen, each of whom have completed more than 120 hours of specialized barehand training and annual, recurrent training to be energized certified.

Barehand crews can safely handle and efficiently repair live lines up to 765kV. On one project, Quanta used barehand techniques to repair a nuclear plants 345kV substation switches in one day without shutting down the reactor. This saved the utility an estimated $10 million the cost associated with shutting down the reactor, making repairs, returning it to operation and making spot market power purchases during the down time.

Coupling the LineMaster Robotic Arm technology with Quantas barehand and hotstick methods provides a complete energized solution that increases efficiency, reliability, levelization, and safety.

Energized Services Case Study

Kansas City Power & Light (KCP&L) was experiencing transmission congestion on its LaCygne-Stilwell Line, representing a major bottleneck for members and customers of the Southwest Power Pool (SPP) who rely on the line for service. Since the line was vital to the service needs of KCP&L and the SPP, taking the line out of service for any extended period of time for upgrades would have proved extremely disruptive in the form of lost revenue, power outages, and angry customers.

Since the line was built in 1972, KCP&L had done a number of system augmentations including substation enhancements at either end of the line as well as installing monitoring equipment that provided incremental capacity as power demand grew over the years. However, as KCP&L looked for additional capacity enhancements for the line, it became clear that KCP&L would have to rebuild or upgrade the line to truly solve its capacity problem.

The advent of a high-temperature conductor, or ACSS (aluminum conductor steel supported), meant that the ACSS could carry twice the load of the conductors KCP&L was using on the line, and that if the 345-kV line could be reconductored with the ACSS, KCP&L could use the existing H-frames supporting the line. If this were able to be done while the line remained energized, the lines capacity problem would be solved and customers would not experience any service disruption.

Because of Quantas unmatched expertise in energized services, proprietary tools and work methods, KCP&L approached Quanta to work toward a rebuild solution on the LaCygne-Stillwell Line. Quanta worked with KCP&L and developed a plan predicated on reconductoring the line while energized. At that time, Quanta had worked on many energized projects for KCP&L, but none of this magnitude.

To do the job, Quanta used the Equal Potential Stringing Method, which isolated the working area and the conductor being pulled, used proprietary processes, tools and equipment to solve complicated issues and completed the project all while the line remained in service. The project ran smoothly and was completed a month ahead of schedule, a major accomplishment given the snow and mud experienced at the start of the project in February and spring rains and storms in May.

In summary, Quanta and KCP&L broke new ground with this project in solving transmission congestion problems and upgrading conductors in an energized state. The project was completed ahead of schedule in under five months and cost less than $8 million. Had the line been replaced using traditional installation methods, the project would have taken longer, required the line to be shut down for periods at a time, been significantly more costly, and been disruptive to customers.

Company Profile				December 2005

Understanding Margins

It is important to understand how various factors some controllable, some not impact Quantas gross margins on a quarterly or annual basis.

		Seasonal & Geographical: Seasonal patterns can have a significant impact on gross margins. Generally, business is slower in the winter months versus the warmer parts of the year. This can be offset somewhat by increased demand for electrical service and repair work from severe weather. In addition, the mix of business conducted in different parts of the country will affect margins; some parts of the country offer the opportunity for higher gross margins than others.

		Weather: Adverse or favorable weather conditions can impact gross margins in a given period. For example, in the first half of 2004, parts of the country experienced record snow or rain fall that negatively impacted Quantas revenue and gross margin. In many cases projects were delayed or had to be temporarily placed on hold. Conversely, in periods where weather remains dry and temperatures are accommodating, more work can be done, sometimes with less cost, which would have a favorable impact in gross margin. In some cases, as in the second half of 2004 and 2005, strong storms or hurricanes can provide Quanta with high margin emergency service restoration work, which has a positive impact on margins.

		Revenue Mix: The mix of revenue derived from the industries we serve will impact gross margins. Changes in our customers spending patterns in each of the industries we serve can cause an imbalance in supply and demand and, therefore, affect margins and mix of revenue by industry served.

		Service and Maintenance versus Installation: In general, installation work has a higher gross margin than maintenance work. This is because installation work is often obtained on a fixed price basis, which has higher risk than other types of pricing arrangements. Quanta typically derives approximately 50% of its revenue from maintenance type work, which is performed under pre-established or negotiated prices or cost-plus pricing arrangements. Thus, a higher portion of installation work in a given quarter may result in a higher gross margin.

		Subcontract Work: Work that has to be subcontracted out generally has lower gross margins. An increase in subcontract work in a given period may contribute to a decrease in gross margin. Quanta typically subcontracts approximately 10%-15% of its work to other service providers.

		Materials versus Labor: Margins may be lower on projects on which Quanta furnishes materials as material prices are generally more predictable than labor costs. Consequently, Quanta generally is not able to mark up materials as much as labor costs. In a given period, a higher percentage of work that has a higher materials component may decrease overall gross margin.

		Depreciation: Quanta includes depreciation in its cost-of-services line. This is common practice in its industry, but can make comparability to other companies difficult. This must be taken into consideration when comparing Quanta to other companies.

		Insurance: Gross margins could be impacted by fluctuations in insurance accruals related to Quantas deductibles in the period in which such adjustments are made. As of September 30, 2005, Quanta had a deductible of $1,000,000 per occurrence related to employers and general liability and a deductible of $2,000,000 per occurrence for automobile liability and workers compensation insurance. Quanta also has a non-union employee related health care benefit plan that is subject to a deductible of $250,000 per claimant per year.

		Selling, General and Administrative Expenses: Selling, general and administrative expenses consist primarily of compensation and related benefits to management, administrative salaries and benefits, marketing, office rent and utilities, communications, professional fees, bad debt expense, letter of credit fees and gains and losses on the sale of property and equipment.

Again, it is important to understand how various factors impact gross margin. Just because gross margin narrows in a quarter may not mean that Quanta is not managing its costs of services well.

Quantas Growth Strategy Steady Organic Growth Supplemented by Selected Acquisitions

As discussed, the past three years have been the most challenging and abnormal operating environments for Quanta and its peers in thirty years. No one could have predicted the severity and depth of the telecommunications industrys collapse and challenging environment for cable television, leading to the significant reduction in network development and maintenance investment. The electric power industry, to a lesser extent, was impacted as well.

Throughout this period, Quanta transitioned from a company focused on growth to a company focused on managing its business in a tumultuous environment. Quanta has been successful in reducing its cost structure, streamlining and focusing on operations, and improving its balance sheet. Though the operating environment has not returned to normal or demonstrated a return to a growth trend, Quanta has positioned itself to operate successfully in the current environment and is well positioned to capitalize on growth opportunities as conditions improve.

In normal market conditions, Quanta enjoyed solid organic revenue growth in excess of 20%. Quanta believes that a sustainable long-term organic revenue growth rate for its business is approximately 10% to 15% in normal operating conditions. This growth will be driven by the need to invest in the expansion and maintenance of the nations power grid and continued development and maintenance of telecommunications and cable television networks as technology continues to develop new applications and services. It will also be driven by increased network infrastructure installation and maintenance outsourcing trends.

Since the founding of Quanta, the Company has augmented its organic growth with strategic acquisitions of top tier companies, enabling it to expand its service offering and geographic reach to better serve its customers. Quanta has not completed an acquisition since early 2002, but as business conditions return to normal, Quanta may elect to selectively and opportunistically pursue the acquisition of companies to continue to enhance its service offering and expand its geographic reach.

We would note that Quanta has not purchased start-up companies or turnarounds, instead focusing on companies with an average operating history of 20 to 30 years and with a record of operational excellence and profitability. Quanta has a disciplined acquisition approach that focuses on various financial, geographic, and management criteria including:

			Solid historical and projected financial performance,

			Internal rate of return, return on assets, and return on revenue benchmarks,

			Management experience and reputation,

			The composition and size of the candidates customer base,

			The candidates impact on increasing or maintaining market share,

			Operational synergies, and

			Any liabilities, contingent or otherwise.

Recent Financial Results & Commentary

Quantas 3Q05 results came in ahead of the Companys previously disclosed 3Q05 financial outlook, with both revenues and diluted EPS exceeding expectations due to solid growth across almost all of the industries Quanta serves and due to emergency storm restoration work performed across the Gulf coast due to hurricanes Katrina and Rita in 3Q05. In 2004, Quanta focused on operations stabilization, maintaining strong customer relationships and strengthening its balance sheet to ensure its ability to serve its customers as their financial strength returns. As Quantas customers have gained financial strength, Quantas year-to-date 2005 results indicate that its operational focus in 2004 is paying off. Quanta believes 2005 will be a building year as the Company continues to see signs that its customers are gaining strength, that the economy has turned the corner and that Quantas long-term future is promising.

3Q05 financial results included the following highlights:

			Revenues were $523.3 million versus previous estimates of $460 to $490 million reflecting 13% internal growth.

			Excluding emergency storm restoration work associated with hurricanes in 3Q05 and 3Q04, electric and gas utility revenues increased 18%.

			Gross margin increased to 15.3% in 3Q05 versus 12.6% in 3Q04. Excluding the impact of an insurance charge in 3Q04 of $8.6 million, gross margin would have been 14.5% in 3Q04.

			Diluted earnings per share was $0.11 in 3Q05 versus the previous 3Q05 diluted earnings per share estimate of between $0.06 and $0.08.

			Backlog at September 30, 2005 was $1.271 billion, up from $1.070 billion at December 31, 2004 and up versus backlog at the same time last year of $1.070 billion.

Revenue for 3Q05 was $523.3 million versus 3Q04 revenue of $463.1 million, which reflected 13% internal growth. Revenues increased due to improved spending patterns by Quantas customers and by most of the industries Quanta serves. 3Q05s higher revenue can also be attributed to a slightly larger amount of storm work being performed in 3Q05 versus 3Q04. Revenues from electric and gas utility customers increased approximately 18% (excluding storm related work in 3Q05 and 3Q04), revenues from telecom and cable customers increased by approximately 5% (combined) and revenues from ancillary customers increased by approximately 11%, all versus the same quarter last year.

Revenue Breakdown by Type of Customer


	Third Quarter
	2004			2005
Electric & Gas Utilities		68	%		69	%
Telecom & Cable TV		15	%		13	%
Ancillary		17	%		18	%

Gross margin (including depreciation expense) in 3Q05 increased to 15.3% versus 12.6% in 3Q04. Excluding the effect of an insurance charge of $8.6 million in 3Q04, gross margin would have been 14.5% in 3Q04. The increase in margins in the quarter was due to improved spending patterns by Quantas customers which resulted in improved margins in all of the primary industries Quanta serves.

3Q05 G&A expenses were $49.4 million, or 9.4% of revenues versus 3Q04 G&A expenses of $44.3 million, or 9.5% of revenues. 3Q05 G&A expenses were higher primarily due to higher salaries and benefits costs, increased personnel, cost of living adjustments, higher performance bonus costs, higher professional fees and higher bad debt expense.

Quantas 3Q05 net income was $12.9 million, or $0.11 per diluted share, versus 3Q04 net income of $4.2 million, or $0.04 per diluted share. 3Q04 results were negatively impacted by a pre-tax insurance charge

of approximately $8.6 million, which did not recur in 3Q05.

Cash flow from operations in 3Q05 was negatively impacted due to increased working capital requirements associated with the $84.1 million sequential increase in revenues in 3Q05 over 2Q05. Year-to-date cash flow from operations through September 30, 2005, was a negative $1 million. Quanta expects its negative cash flow from operations to reverse substantially by the end of 2005 as receivables are collected for work performed over the past quarter. Year-to-date capital expenditures as of September 30, 2005, were $38.9 million.

Quantas backlog at the end of 3Q05 was $1.271 billion, up from 4Q04 backlog of $1.070 billion, and up versus 2Q05 backlog of $1.200 billion. For 3Q05, Quantas largest customer accounted for 5% of revenues. Quantas top 10 customers for the quarter accounted for 36% of revenues and top 20 customers accounted for 49% of revenues. At the end of 3Q05, Quantas employee count was 11,572 versus 11,161 at the end of 2Q05.

Quantas days sales outstanding (DSO), which includes current accounts receivable plus costs and estimated earnings in excess of billings on uncompleted contracts less billings in excess of costs and estimated earnings on uncompleted contracts, was 86 days at the end of 3Q05 versus 85 days at the end of 2Q05 and versus 85 days at the end of 3Q04. DSOs tend to peak in the first quarter of a given year and decline over the balance of the year. Quantas believes its DSOs can decline slightly by the end of the year.

At its peak in 3Q05, Quanta had more than 2,000 of its line personnel from all corners of North America working in areas affected by hurricanes Katrina and Rita. These individuals worked to clear vegetation, remove downed power and phone lines, repair damaged infrastructure and rebuild phone and power transmission and distributions systems where necessary. Quantas rapid and large mobilization of its people in response to the hurricanes demonstrates the Companys ability to respond to its customers. Though most of the power has been restored in affected areas, the work to truly repair damaged power systems has just begun. Entergy has estimated damage from hurricane Katrina to be in the range of $750 million to $1.1 billion. Damage from Rita to Entergys system alone may reach as much as $550 million. For Entergy, Rita alone affected more than 340 transmission lines and 430 substations. More than one million customers experienced power outages as a result of hurricane Katrina and more than 760,000 customers lost power due to hurricane Rita. These numbers were recently exceeded by the impact of hurricane Wilma, which left six million customers without power. Quantas crews remain deployed throughout the Gulf Coast and in Florida to help its customers repair their systems.

The hurricanes generated a great deal of news coverage and as discussed, Quanta participated in helping

affected areas restore power. However, excluding storm related work in 3Q05 and 3Q04, electric and gas utility revenues increased by 18% in 3Q05 over the same period last year. In addition, Quantas telecom and cable TV revenues increased by approximately 5% and revenues from ancillary services increased by 11%. This solid growth across almost all of Quantas core industries continues to illustrate improved spending patterns by its customers due to their continuing improvement in financial health and outlook for the future. The operational outlook for the remainder of the year appears favorable and Quanta is optimistic that operating conditions will continue to improve through 2006.

There are three major trends in the electric utility sector that make this an exciting time for Quanta: (1) a comprehensive energy bill, certain sections of which address the state of the power delivery system, was signed by the President on August 8, 2005, (2) increased spending by many of its customers who have strengthened their balance sheets and overall financial health over the past several quarters and (3) increasing interest in outsourcing as a way to reduce costs while maintaining quality service to the customer.

Among other things, the energy bill is aimed at improving the nations electric transmission capacity, reliability and promoting investment in the nations energy infrastructure. Specifically, the bill establishes a self-regulating reliability organization that will enforce mandatory reliability rules on all market participants, with oversight by the FERC. The bill also grants the FERC limited backstop citing authority for critical transmission projects if states do not act. The bill also designates the Department of Energy as the lead agency to help streamline the federal permitting process for transmission facilities. These two elements of the bill should contribute to a streamlined, smoother and shorter permitting process, which should make investment in the nations transmission system more attractive.

Lastly, the bill modifies a longstanding barrier to effective competition by repealing the Public Utility Holding Company Act (PUHCA). The repeal of PUHCA will bring new players into the industrys investment landscape. These non-utility investors will focus solely on driving costs down, while enabling the utility to focus on their core competencies. Quanta believes there may be increased interest in outsourcing solutions as a result of the PUHCA repeal.

As a result, Quanta expects utilities to evaluate the condition of their infrastructure more closely and act on much needed upgrades to meet the higher reliability standards. Signage of the bill may not yield an immediate positive impact on Quantas business, but the positive impact of more active infrastructure investment by utilities should begin in the next twelve to eighteen months.

Quantas telecommunications operations continue to see pockets of activity spurred by a variety of factors, including regulatory changes, various FTTx initiatives, merger and acquisition activity and a recovering economy. At the end of 3Q05, Quantas telecom backlog had increased 14% sequentially over 2Q05. Of note, Texas recently became the first state to pass legislation that allows video service providers to get one franchise license for the entire state. This will dramatically reduce the time and money required for Quantas wireline customers to offer TV services in more than one Texas city. These developments, combined with demand for new technologies from consumers and businesses alike, should contribute to a continuing recovery for the telecommunications industry throughout 2005 and 2006.

Positive regulatory developments over the past few months have fueled optimism in the industry and have the potential to increase spending. For example, a bill called The Broadband Investment and Consumer Choice Act of 2005 was recently introduced to the Senate that would replace the Telecommunications Act of 1996. If approved, the bill would deregulate services, roll back current restrictions on providing video services and ultimately assure consumer access to Internet-based phone services.

Company Profile				December 2005

In addition, on August 5, 2005, the Federal Communications Commission (FCC) adopted policies that should bring more and better broadband services to consumers by eliminating facilities sharing requirements on facilities-based wireline broadband Internet access service providers. Specifically, it puts wireline broadband Internet access service, commonly delivered through DSL technology, on an equal regulatory footing with cable modem service. While wireline Internet service providers will have to continue to provide existing wireline facilities access to unaffiliated ISPs for one year, this policy change should encourage network investment in broadband services and over time, increased network spending.

Quanta has continued to focus on the quality of margins on projects rather than pursue a large quantity of work, which has had a favorable impact on overall telecom margins. The Company continued to see robust activity and progression of FTTx projects in 3Q05 and Quanta continues its work for Verizon in a number of states across the country. Verizon recently reaffirmed that it has passed 2.5 million homes in 15 states and is on track to reach three million homes by year end. Verizon also announced that it plans to pass an additional three million homes and businesses next year. In addition, SBC recently completed its field test of Project Lightspeed and Quanta expects SBCs fiber to the node initiative to gain momentum through the balance of 2005 and into 2006, as SBC expects to have deployed the necessary fiber to pass two million homes with Lightspeed service by the end of 2005. BellSouth too has become more vocal about its fiber to the curb initiatives and announced that it plans to accelerate its deployment due to recent positive regulatory court rulings. BellSouth plans to deploy fiber to almost 60% more locations in 2005 than it did in 2004. The momentum behind fiber deployments deeper into the network is not limited to the large telcos such as Verizon and SBC, but is also coming from smaller telephone companies, municipalities, rural telcos and other industry participants.

Outlook

The following statements are based on current expectations. These statements are forward-looking, and actual results may differ materially due to various risks and uncertainties as further described on page 37 of this Company Profile.

For 4Q05, Quanta expects revenues to range from $450 million to $480 million and that diluted EPS will range between $0.06 to $0.08. This compares to diluted EPS of $0.02 in 4Q04. Quanta expects operating margins of between 4% and 5% in 4Q05. The Company estimates its tax rate in 4Q05 will be approximately 50% and its diluted share count for 4Q05 to be approximately 117 million. Regarding cash flow, using the midpoint of the Companys 4Q05 revenue range and assuming that DSOs are at 83 days, Quanta estimates it could generate approximately $85 million in cash flow from operations in 2005. Quanta estimates its capital expenditures for full year 2005 to be approximately $44 million.

Peer Operation & Valuation Comparison

The specialty contracting industry is highly fragmented and very competitive. Quanta estimates that its annual addressable market is approximately $30 billion to $40 billion. Quanta believes that the top five specialty contractors (based on revenues) account for approximately 15% of this annual market opportunity. Quanta estimates that it commands the largest portion of this estimated 15% share, but that it is less than 5% of the total addressable market. The remaining 85% market share is held by smaller, private specialty contracting companies.

With its diversified service offering and customer base, and national presence, Quanta is unique. Below is a table of Quantas peers, indicating the various markets each specialty contractor serves. Also included is a peer valuation analysis of a broader peer group that includes several companies in the construction and engineering sector. While Quanta may not compete directly with some of these companies, they are included because they perform construction and engineering services and are often impacted by similar macro and/or other trends as Quanta. Of this peer group, InfraSource, Dycom Industries and MasTec are Quantas closest public peers. However, both Dycom and MasTec focus more on the telecommunications and cable television industries and InfraSource does not have as large a geographic presence as Quanta does.

Upon initial election to the Board of Directors at an annual meeting of stockholders, each such initially elected non-employee director receives an annual cash retainer payment of $30,000 and an annual award of shares of restricted common stock having a value of $120,000.
