	Demand for Voice, Video and Data Services. Demand for faster and more robust voice, video and data services has increased significantly with the proliferation of the internet, broadband and advanced video services. To serve this developing market, voice, video and data service providers are upgrading the performance of their networks or deploying new networks. Investment is facilitated by declining equipment costs and expanded capabilities of network equipment. In addition, the service offerings of our customers are converging as telephone and cable providers increasingly seek to deploy networks that allow them to provide bundled voice, video and data services to their customers. Verizon Communications, BellSouth and SBC Communications have each announced initiatives to upgrade their networks from copper line to fiber optic line in order to enhance their ability to provide full bundled service offerings. Cable companies continue to upgrade their systems to provide for enhanced broadband services, including voice over internet protocol as well as improved video offerings, including digital television, high definition television, video on demand and digital video recording. Satellite television subscriptions and installations have grown substantially over the last five years as the industry has gained acceptance in part through offering attractive programming such as NFL Sunday Ticket, as well as high definition television and digital video recorder capabilities. According to a 2005 study by J.D. Power and Associates, the percentage of U.S. households with telephones that subscribe to satellite service has grown from 12% in 2000 to 27% in 2005.
	Increased Outsourcing of Network Infrastructure Installation and Maintenance. We provide specialized services that are labor and equipment intensive. According to a study by management consulting firm Booz Allen Hamilton described in an article entitled “Outsourcing Trends in the North American Telecommunications Markets,” more than 75% of telecommunications executives consider outsourcing an important component of their business that allows them to better respond to market challenges, and network installation and maintenance are among functions most likely to be outsourced. We believe that communications companies view outsourcing as an opportunity to reduce expenses, optimize expenditures and stay competitive.
	Inadequacy of Existing Electric Power Transmission and Distribution Networks. The United States electric transmission and distribution infrastructure requires significant ongoing maintenance, upgrades and extensions to manage powerline congestion, avoid delivery failures and connect distribution lines to new end users. According to a 2004 Edison Electric Institute report annual transmission and distribution spending in the U.S. has been between $12 and $17 billion annually since 1980. Despite this significant spending since 1980, the pace of transmission investment has

	lagged behind total electricity generation. Such underinvestment combined with ever-increasing load demand contributed to the rolling blackouts in California in 2001 as well as the August 2003 blackout, which left 50 million people in the midwest and northeast United States and Canada without electricity. As a result, we believe that that transmission and distribution spending will continue and likely rise in the near future in order to meet the increasing needs of customers.
	Increased Funding for Energy Projects. On August 8, 2005, President Bush signed the Energy Policy Act of 2005 into law. The law was passed to develop more reliable supply chains and distribution channels for U.S. energy resources. Among other things, the bill facilitates the siting, construction and financing of more reliable electrical grid components. As a result, we believe that transmission and distribution spending will continue and likely rise in the near future in order to meet the increasing needs of consumers and businesses.
	Increased Funding for Highway Transportation Projects. On August 10, 2005, President Bush signed a six-year $244.1 billion transportation reauthorization bill known as the Safe, Accountable, Flexible and Efficient Transportation Equity Act: A Legacy for Users. The new law funds federal highway, maintenance, bridge, safety and congestion mitigation programs. Management estimates that up to 5 percent of this funding may be allocated to projects that involve intelligent transportation systems. These projects encompass traffic management solutions such as video surveillance systems, variable message signs, radar detection devices and traffic signal systems, combined with related highway lighting, signage and construction services.

	National Capability and Brand. We, or our predecessors, have been in business for over 70 years and are one of the largest companies in our industry. Through our network of approximately 220 locations and 7,700 employees as of December 31, 2005 across the United States and in Canada, we offer comprehensive infrastructure services to our customers. We believe our experience, technical expertise and size are important to our customers, which include some of the largest communications and utility companies in the United States. Our size and national capability allow us to allocate people, equipment and resources when and where needed. We offer all of our services under the MasTec service mark and maintain uniform performance standards across projects, geographic areas and industries.
	Ability to Respond Quickly and Effectively. The services we provide to the various industries we serve are similar which allows us to utilize qualified personnel across multiple industries. We are able to respond quickly and effectively to industry changes and major weather events by allocating our employees, fleet and other assets as and where they are needed. For example, we were able to redeploy hundreds of our employees and assets from several project teams to areas impacted by Hurricane Katrina within days of the storm striking Louisiana and Mississippi.
	Customer Base. Our customers include some of the largest communication and utility companies in the United States, including DirecTV, Verizon Communications, BellSouth, Sprint Nextel and Florida Power and Light. These customers have significant infrastructure needs and the financial resources necessary to fund those needs. We provide services to many of our significant customers under multi-year master service agreements and other service agreements.
	Reputation for Reliable Customer Service and Technical Expertise. We believe that over the years we have established a reputation for quality customer service and technical expertise. We are one of the largest private label in-home installation and maintenance service providers for DirecTV. A 2004 study described in an article entitled “As Satellite TV Penetration Grows, Overall Customer Satisfaction among Satellite Subscribers Continues to Top Cable” by J.D. Power and Associates recognized DirecTV for achieving one of the highest levels of customer satisfaction in

Table of Contents

	its market. We believe that the training and performance of our technicians contributed to DirecTV’s high level of customer satisfaction. We also believe our reputation for technical expertise gives us an advantage in competing for new work. For example, one of our communications customers has selected us as one of their primary fiber to the home subcontractors.
	Experienced Management Team. Our management team, which includes our chief executive officer, service group presidents and financial officers, plays a significant role in establishing and maintaining long-term relationships with our customers, supporting the growth of our business and managing the financial aspects of our operations. Our chief executive officer, Austin J. Shanfelter, has over 24 years of experience in the network infrastructure construction business and is well-known in the industry. Our service group presidents average 28 years of industry experience and have a deep understanding of our customers and their requirements. Our financial officers, including our service group chief financial officers, average 22 years of experience and allow us to operate our business effectively by reducing costs and enhancing our control environment.

	Capitalize on Favorable Industry Trends. Many of our customers have increased spending on their network infrastructure in order to enhance their ability to offer voice, video and data services, deliver electric power or improve the logistics of their transportation networks. In addition, many companies are increasing outsourcing network installation and maintenance work. We intend to use our national presence and full range of services to capitalize on these trends to generate additional revenue from existing and new customers.
	Operate More Efficiently. We have recently taken action and instituted programs to improve our operating efficiencies and working capital management, such as hiring additional experienced operating and financial professionals at the service group and corporate levels, requiring increased accountability throughout our organization, expanding the use of our Oracle management information systems throughout our business, better managing customer contract bidding procedures and increasing individual project profitability. We intend to improve our operating effectiveness by allocating our resources across multiple customers and projects which will continue to increase our utilization rates. We intend to continue to capture operating efficiencies and improve working capital management in order to increase our operating margins and cash flows.
	Improve Our Financial Strength. With the proceeds of this offering, we intend to reduce our debt and increase our cash, which will significantly improve our financial condition. We believe improvements to our financial condition will enhance our credit rating and support our ability to reduce our collateral for our surety bonds and insurance policies.
	Acquisitions, Strategic Alliances and Divestitures. We intend to pursue selected acquisitions and strategic alliances. We will focus on acquisitions and alliances that allow us to expand our operations into targeted geographic areas or allow us to expand our service offerings in areas that require skill sets or equipment that we do not currently maintain. Our strategy will include timely and efficient integration to best fit into our internal control environment. We may also consider sales or divestitures of portions of our assets, operations, real estate or other properties.

	Some of the work we perform is in underground environments. If the field location maps supplied to us are not accurate, or if objects are present in the soil that are not indicated on the field location maps, our underground work could strike objects in the soil containing pollutants and result in a rupture and discharge of pollutants. In such a case, we may be liable for fines and damages.
	We own and lease several facilities at which we store our equipment. Some of these facilities contain fuel storage tanks which may be above or below ground. If these tanks were to leak, we could be responsible for the cost of remediation as well as potential fines.
	We sometimes perform directional drilling operations below certain environmentally sensitive terrains and water bodies. Due to the inconsistent nature of the terrain and water bodies, it is possible that such directional drilling may cause a surface fracture releasing subsurface materials. These releases may contain contaminants in excess of amounts permitted by law, potentially exposing us to remediation costs and fines.

(2)	All options were granted at an exercise price equal to fair market value based on the closing price of our common stock on the New York Stock Exchange on the date of grant.
(3)	Amounts represent hypothetical gains assuming exercise at the end of the option term and assuming rates of stock price appreciation of 5% and 10% compounded annually from the date the respective options were granted to their expiration date. The 5% and 10% assumed rates of appreciation are mandated by the rules of the Securities and Exchange Commission. These assumptions are not intended to forecast future appreciation of our stock price. The potential realizable value computation does not take into account federal or state income tax consequences of option exercises or sales of appreciated stock. The actual gains, if any, on the stock option exercises will depend on the future performance of our common stock, the optionee’s continued employment through applicable vesting periods and the date on which the options are exercised and the underlying shares are sold.

	Management identified weaknesses in internal controls involving inventory practices and policies in the Company’s ITS division, with respect to inventory pricing on receipt and the related cost of revenue, and inventory tracking prior to sale or use.
