PART I

Item 1.Business

Overview

We are a leading specialty contractor operating mainly throughout the United States and across a range of industries. Our core activities are the building, installation, maintenance and upgrade of communications and utility infrastructure. Our primary customers are in the following industries: communications (including satellite television and cable television), utilities and government. We provide similar infrastructure services across the industries we serve. Our customers rely on us to build and maintain infrastructure and networks that are critical to their transportation and delivery of voice, video and data communications, electricity and other energy resources.

We, or our predecessor companies, have been in business for over 70 years. We offer our services under the MasTec^{^®} service mark and operate through a network of approximately 200 locations and 8,240 employees as of December 31, 2007. Providing services to communication industries, utility industries and government markets, we have consistently ranked among the top specialty contractors by Engineering News-Record.

Our customers include some of the largest communication and utility companies in the United States, including DIRECTV^®, Verizon, AT&T, EMBARQ, Progress Energy, Florida Power & Light, TXU, Qwest, XTO Energy, and Dominion Virginia Power. For the years ended December 31, 2007, 2006 and 2005, 76.7%, 76.4% and 74.4%, respectively, of our revenues were from our ten largest customers. We have longstanding relationships with many customers and often provide services under multi-year master service agreements and other service agreements. For the years ended December 31, 2007, 2006 and 2005, 72.3%, 74.3% and 68.7%, respectively, of our revenues were derived under multi-year master service agreements and other service agreements.

Industry Trends

Our industry is comprised of national, regional and local companies that provide outsourced infrastructure services to customers in the communications and utilities industries as well as government customers.

We believe the following industry trends impact demand for our services:

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, video and music download services, high definition television and other advanced video services. To serve this developing market and the ever-increasing need for more bandwidth, 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 wireline and wireless 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, and advanced video and data services to their customers. Verizon, AT&T, Qwest and numerous regional and rural telecommunication companies are upgrading 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, commonly called VOIP, 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, NASCAR HotPass, and other exclusive sports offerings as well as high definition television and digital video recorder capabilities.

Increased Outsourcing of Network Infrastructure Installation and Maintenance.We provide specialized services that are labor and equipment intensive. We believe that communications companies view outsourcing as an opportunity to reduce expenses, manage capital costs 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. Despite significant spending since 1980, the pace of transmission investment has lagged behind total electricity generation investment. Such underinvestment, combined with ever-increasing load demand, contributed to the blackouts, brownouts and rolling blackouts nationwide since 2001, which have periodically left millions in the United States without electricity. 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 customers. According to a 2005 Edison Electric Institute report, transmission and distribution spending in the U.S. is expected to average approximately $19 billion annually through 2015.

Alternative Energy Projects. As utilities search for more environmentally sensitive ways to generate electrical power, the number of alternative energy generation projects, such as wind and solar collection farms, has been expanding rapidly. According to the American Wind Energy Association, in the 4^th quarter of 2007, the U.S. had 16,819 megawatts of installed wind farm generating capacity with another 3,506 megawatts currently under construction. These projects are often located in areas where there is no other generation capacity. We believe that extensive collection and transmission projects are necessary to connect these projects to the electrical grid.

Increased Funding for Energy Projects.The Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007 were passed to develop more reliable supply chains and distribution channels for U.S. energy resources. Among other things, the Energy Policy Act facilitates the siting, environmental compliance, construction and financing of more reliable electrical grid components. The Energy Independence and Security Act promotes a number of research and development initiatives that could lead to increased spending on the nations energy infrastructure and the facilitation of the development of alternative energy projects. As a result, we believe that transmission and distribution spending will likely rise in the near future in order to meet the increasing needs of consumers and businesses.

Competitive Strengths

Our competitive strengths include:

National Capability and Brand.We, or our predecessor companies, have been in business for over 70 years and we are one of the largest companies in our industry. Through our network of approximately 200 locations and 8,240 employees across the United States, 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 when and where they are needed.

Customer Base.Our customers include some of the largest communication and utility companies in the United States, including DIRECTV^®, Verizon, AT&T, EMBARQ, Progress Energy, Florida Power & Light, Qwest, XTO Energy, TXU and Dominion Virginia Power. 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 believe that we are one of the largest private label in-home installation and maintenance service providers for DIRECTV^®. A 2007 study by J.D. Power and Associates recognized DIRECTV^® for achieving one of the highest levels of customer satisfaction in many of its markets. We believe that the training and performance of our technicians contributed to DIRECTV^{^®’}shigh level of customer satisfaction. We also believe our reputation for technical expertise gives us an advantage in competing for new work from the home installation customers.

Experienced Management Team.Our management team, which includes our chief executive officer, chief operating 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, chief operating officer and service group presidents have a deep understanding of our customers and their requirements.

Strategy

The key elements of our business strategy are as follows:

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 other energy resources. In addition, many companies are increasing outsourcing network installation and maintenance work. We intend to increase the percentage of business derived from large, financially stable customers in the communications and utility industries. We also 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 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.We have increased our financial resources in recent years with receipt of the net proceeds from the public offering of our common stock in 2006 and the offering of our senior notes in 2007. These actions have significantly improved our financial condition. We believe these improvements to our financial condition have enhanced our credit worthiness and support our ability to reduce our collateral requirements 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. 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, projects, real estate or other properties.

Services

Our core services are building, installing, maintaining and upgrading infrastructure for our communications, utility and government customers. We provide each of these customers with similar services that include:

Build.We build underground and overhead distribution systems, such as trenches, conduits, power lines and pipelines, that are used by our customers in networks that provide communications and power delivery.

Install.We install buried and aerial fiber optic cables, coaxial cables, copper lines, electrical and other energy distribution systems, transmission systems and satellite dishes in a variety of environments for our customers. In connection with our installation work, we deploy and manage network connections that involve our customers’ hardware, software and network equipment.

Maintain and Upgrade.We offer 24-hours-a-day, 7-days-a-week and 365-days-a-year maintenance and upgrade support to our customers. Our comprehensive service offerings include the regular maintenance of our customers’ distribution facilities and networks as well as emergency services for accidents or storm damage. Our upgrade work ranges from routine replacements and upgrades to major network overhauls.

Customers

Our primary customers are in the communications, utilities industries and the government markets. We provide similar infrastructure services across the industries we serve. For the year ended December 31, 2007, 74.2%, 20.9% and 4.9% of our revenues were from customers in the communications, utilities and government industries, respectively. In the year ended December 31, 2007, we derived approximately 44.1%, 9.1% and 6.8% of our revenue from DIRECTV^®, Verizon and AT&T, respectively.

We have longstanding relationships with many customers and often provide services under multi-year master service agreements and other service agreements. For the years ended December 31, 2007, 2006 and 2005, 72.3%, 74.3% and 68.7%, respectively, of our revenues were derived under master service agreements and other service agreements. While our multi-year master service agreements and other service agreements generally do not guarantee a specific level of work and are generally cancelable upon short notice, the agreements have historically been an important contributor to our revenue and backlog.

We believe that our industry experience, technical expertise and customer service are important to our being retained by large communications and utility companies and governments. The relationships developed between these customers and our senior management and project management teams are also important to our being retained.

Backlog

At December 31, 2007 and December 31, 2006, our 18-month backlog was approximately $1.3 billion and $1.1 billion, respectively. We expect to realize approximately 70.3% of our 2007 backlog in 2008. Approximately 85.3% of our backlog at December 31, 2007 was comprised of services to be performed under existing master service agreements and long term contracts. The balance is our estimate of work to be completed on other service agreements.

Sales and Marketing

We market our services individually and in combination with other companies to provide what we believe is the most efficient and effective solution to meet our customers’ demands, which increasingly require resources from multiple disciplines. Through our unified MasTec^® brand and an integrated organizational structure designed to permit rapid deployment of labor, equipment and materials, we are able to quickly and efficiently allocate resources to meet customer needs.

We have developed a marketing plan emphasizing the MasTec^® registered service mark and an integrated service offering to position ourselves as a provider of a full range of service solutions, providing services ranging from basic installation to sophisticated engineering, design and integration. We believe our long-standing relationships with our customers and reputation for reliability and efficiency facilitate our recurring business. Our marketing efforts are principally carried out by the management of our service groups in coordination with our corporate marketing organization. Our management team has many years of industry experience, both at the service provider level and in some cases with the customers we serve. Our service group managers market directly to existing and potential customers for new contracts and also market our company to be placed on lists of vendors invited to submit proposals for service agreements and individual projects. Our executive management supplements these efforts at the national level.

Safety and Insurance/Risk Management

We strive to instill safe work habits in our employees. We require our employees to participate in internal training and service programs relevant to their employment and to complete any training programs required by law. We evaluate employees in part based upon their safety records and the safety records of the employees they supervise. We have established a company-wide safety program to share best practices and to monitor and improve compliance with safety procedures and regulations.

Our business involves heavy equipment and exposure to conditions that can be dangerous. While we are committed to operating safely and prudently, we are subject to claims by employees, customers and third parties for property damage and personal injuries that occur in connection with our work. See “Item 1A. Risk Factors — Our business is subject to hazards that could result in substantial liabilities and weaken our financial condition.”

Suppliers, Materials and Working Capital

Under most of our contracts, our customers supply the necessary materials and supplies and we are responsible for installation, but not for material costs or material warranties. Under certain of our contracts we acquire materials and supplies for our own account from third-party providers. We are not dependent on any one supplier for materials or supplies and have not experienced any significant difficulty in obtaining an adequate supply of materials and supplies.

We utilize independent contractors to assist on projects and to help us manage work flow. Our independent contractors are typically sole proprietorships or small business entities that provide their own vehicles, tools and insurance coverage. We are not dependent on any single independent contractor. See “Item 1A. Risk Factors — We may choose, or be required, to pay our subcontractors even if our customers do not pay, or delay paying, us for the related services.”

We need working capital to support seasonal variations in our business, primarily due to the impact of weather conditions on external construction and maintenance work, including storm restoration work, and the corresponding spending by our customers on their annual capital expenditure budgets. Our business is typically slower in the first and fourth quarters of each calendar year and stronger in the second and third quarters. We generally experience seasonal working capital needs from approximately April through September to support growth in unbilled revenue and accounts receivable, and to a lesser extent, inventory. Our billing terms are generally net 30 to 60 days, although some contracts allow our customers to retain a portion (from 2% to 15%) of the contract amount until the contract is completed to their satisfaction. We maintain inventory to meet the material requirements of some of our contracts. Some of our customers pay us in advance for a portion of the materials we purchase for their projects, or allow us to pre-bill them for materials purchases up to a specified amount.

Competition

Our industry is highly competitive and highly fragmented. We often compete with a number of companies in markets where we operate, ranging from small local independent companies to large national firms. The national or large regional firms that compete with us include Dycom Industries, Inc., Pike Electric, Inc. and Quanta Services, Inc.

Relatively few significant barriers to entry exist in the markets in which we operate and, as a result, any organization that has adequate financial resources and access to technical expertise may become a competitor. Some of our customers employ personnel to perform infrastructure services of the type we provide. We compete based upon our industry experience, technical expertise, financial and operational resources, nationwide presence, industry reputation and customer service. While we believe our customers consider a number of factors when selecting a service provider, most of their work is awarded through a bid process. Consequently, price is often a principal factor in determining which service provider is selected. See “Item 1A. Risk Factors — Our industry is highly competitive which may reduce our market share and harm our financial performance.”

Regulation

We are subject to state and federal laws that apply to businesses generally, including laws and regulations related to labor relations, worker safety and environmental protection. While many of our customers operate in regulated industries (for example, utilities regulated by the public service commission or broadband companies regulated by franchise agreements with various municipalities), we are not generally subject to such regulation and oversight.

As a contractor, our operations are subject to various laws, including:

	•		regulations related to vehicle registrations, including those of state and the United States Departments of Transportation;

	•		regulations related to worker safety and health, including those established by the Occupational Safety and Health Administration;

	•		contractor licensing requirements;

	•		building and electrical codes; and

	•		permitting and inspection requirements.

We are also subject to various environmental laws. Our failure to comply with environmental laws could result in significant liabilities. For example,

•

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.

See “Item 1A. Risk Factors — Our failure to comply with environmental laws could result in significant liabilities.”

We believe we have all licenses and permits needed to conduct operations and that we are in compliance with all material applicable regulatory requirements. However, if we fail to comply with any material applicable regulatory requirements, we could incur significant liabilities. See “Item 1A. Risk Factors — Our failure to comply with regulations of the U.S. Occupational Safety and Health Administration, the U.S. Department of Transportation and other state and local agencies that oversee transportation and safety compliance could reduce our revenue, profitability and liquidity.”

We offer services and are branded under the MasTec^® service mark. We do not have any patents that are material to our business.

Financial Information About Geographic Areas

During the years ended December 31, 2007, 2006 and 2005, we operated in the United States and Canada. In March 2007, we declared our Canadian operations as discontinued. On April 10, 2007, we sold substantially all of our Canadian operations. Accordingly, our results of operations for all periods presented reflect our Canadian business as discontinued. As of December 31, 2007, we operate almost exclusively in the United States.

Employees

As of December 31, 2007, we had approximately 8,240 employees. We hire employees from a number of sources, including our industry, trade schools and colleges. Our primary sources for employees include promotion from within, team member referrals, print and Internet advertising and direct recruiting. We attract and retain employees by offering technical training opportunities, bonus opportunities, stock ownership, competitive salaries and a comprehensive benefits package.

We believe that our focus on training and career development helps us to attract and retain employees. Our employees participate in ongoing educational programs, many of which are internally developed, to enhance their technical and management skills through classroom and field training. We provide opportunities for promotion and mobility within our organization that we also believe helps us to retain our employees. We believe our relations with our employees are good.

Recent Developments

Settlement Agreement with Buyer of Our State Department of Transportation Related Projects and Assets

Effective February 1, 2007, we sold our state Department of Transportation related projects and assets. On January 24, 2008, we entered into a settlement agreement with the buyer of our state Department of Transportation projects and assets to settle previously disclosed warranty, indemnification and other claims primarily relating to work we had performed on the state Department of Transportation projects we sold. In connection with the settlement agreement, the parties also agreed to further amend and restate the Amended Asset Purchase Agreement effective as of January 24, 2008, which we refer to as the “Revised Amended Agreement.”

Under the terms of the settlement agreement, we paid $6 million in cash and obtained from the buyer a covenant not to sue and general release from nearly all obligations owed by us to the buyer under the purchase agreement, including warranty and other indemnification obligations. The Revised Amended Agreement, among other things, deleted substantially all of our representations and warranties and indemnification obligations set forth in the Amended Asset Purchase Agreement, reduced the term of our covenants against competition and solicitation of customers, suppliers and other third parties (other than the buyer’s employees) from the five year period ending February 13, 2012 to the four year period ending February 13, 2011 and released us from our covenant not to compete in the following states: Arizona, Nevada, Colorado, Oklahoma, New Mexico, Missouri and Minnesota. See “Item 1A. Risk Factors — Risks Related to Our Business — We have agreed to keep certain liabilities related to the state Department of Transportation related projects and assets that were sold in February 2007.”

Risks Related to Our Industry and Our Customers’ Industries

An economic downturn or reduced capital expenditures in the industries we serve may result in a decrease in demand for our services.

Beginning in the fourth quarter of 2007 and continuing into 2008, a number of key economic indicators including the Consumer Confidence Index, US Leading Index, Consumer Price Index (‘CPI’), and total new housing starts have been trending downward and pointing in the direction of a potential economic downturn during 2008. Because we have been negatively impacted by previous economic downturns, we constantly monitor our customers industries and their relative health compared to the economy as a whole. The aforementioned reduction in new housing starts, should it continue during 2008, could negatively impact our customers who utilize our services to construct their ‘last mile’ of infrastructure. Continued reductions in new housing starts, which generally follow overall economic trends, could result in the cancellation of certain projects or a reduction in the utilization of our services until these sectors of the economy improve. Additionally, our customers who provide satellite communications to consumers across the country could be adversely impacted by an economic downturn if new subscriptions and upgrades for new and existing consumers are not ordered at the rate that we and our customers anticipate. Moreover, during an economic downturn, our customers may not have the ability or desire to continue to fund capital expenditures for infrastructure at their current levels. A decrease in either ‘last mile’ projects, new subscriptions and upgrades or any other services we provide could adversely affect our results of operations, cash flows and liquidity.

Many of the industries we serve are subject to consolidation and rapid technological and regulatory change, and our inability or failure to adjust to our customers’ changing needs could reduce demand for our services.

We derive, and anticipate that we will continue to derive, a substantial portion of our revenue from customers in the communications industry. The communications industry is subject to rapid changes in technology and governmental regulation. Changes in technology may reduce the demand for the services we provide. New or developing technologies could displace the wire line systems used for the transmission of voice, video and data, and improvements in existing technology may allow communications

providers to significantly improve their networks without physically upgrading them. Additionally, the communications industry has been characterized by a high level of consolidation that may result in the loss of one or more of our customers. Utilities have also entered into a phase of consolidation similar to the communications industry which could lead to the same uncertainties.

Our industry is highly competitive which may reduce our market share and harm our financial performance.

Our industry is highly fragmented, and we compete with other companies in most of the markets in which we operate, ranging from small independent firms servicing local markets to larger firms servicing regional and national markets. We also face competition from existing or prospective customers that employ in-house personnel to perform some of the same types of services we provide. There are relatively few barriers to entry into the markets in which we operate and, as a result, any organization that has adequate financial resources and access to technical expertise and skilled personnel may become one of our competitors.

Most of our customers’ work is awarded through a bid process. Consequently, price is often the principal factor in determining which service provider is selected, especially on smaller, less complex projects. Smaller competitors are sometimes able to win bids for these projects based on price alone due to their lower costs and financial return requirements.

Risks Related to Our Business

We derive a significant portion of our revenue from a few customers, and the loss of one of these customers or a reduction in their demand for our services could impair our financial performance.

For the year ended December 31, 2007, we derived approximately 44.1%, 9.1% and 6.8% of our revenue from DIRECTV^®, Verizon, and AT&T, respectively. In the year ended December 31, 2006, we derived approximately 37.5%, 10.2% and 8.3% of our revenue from DIRECTV^®, AT&T, and Verizon, respectively. In addition, our ten largest customers accounted for approximately 76.7%, 76.4% and 74.4% of our revenue in the years ended December 31, 2007, 2006 and 2005, respectively.

Because our business is concentrated among relatively few major customers, our revenue could significantly decline if we lose one or more of these customers or if the amount of business we obtain from them is reduced, which could result in reduced profitability and liquidity.

Our profitability and liquidity could decline if certain customers reduce the amounts they pay for our services or if our customers are unable to pay for our services.

In the past, we incurred significant losses after a number of customers filed for bankruptcy or experienced financial difficulties following a general economic downturn and certain industry specific factors that worsened the impact of the overall economic downturn on those customers. See “Risks Related to Our Industry and Our Customers’ Industries”, specifically the risk factor entitled “An economic downturn or reduced capital expenditures in the industries we serve may result in a decrease in demand for our services”. In 2007, 2006 and 2005 total provisions for bad debts aggregated to $17.6 million, $10.0 million and $4.9 million, respectively, of which $14.1 million, $7.9 million and $3.7 million, respectively, resulted from anticipated legal settlements and discontinued operations. As of December 31, 2007, we had remaining receivables from customers undergoing bankruptcy reorganization totaling $1.6 million, of which $0.3 million is included in specific reserves for bad debts, with the remaining amounts expected to be recovered through secured and unsecured claims and enforcement of liens or bonds.

Most of our contracts do not obligate our customers to undertake any infrastructure projects or other work with us.

A significant portion of our revenue is derived from multi-year master service agreements and other service agreements. Under our multi-year master service agreements and other service agreements, we contract to provide customers with individual project services, through work orders, within defined geographic areas on a fixed fee basis. Under these agreements, our customers have no obligation to undertake any infrastructure projects or other work with us. A significant decline in the projects customers assign us under these service agreements could result in a decline in our revenue, profitability and liquidity.

We recorded an unrealized loss in 2007 to reduce the carrying value of certain auction rate securities we hold, and we may incur additional impairment charges with respect to auction rate securities in future periods.

The current overall credit concerns in capital markets may affect our ability to liquidate certain securities that we classify as securities available for sale on our balance sheet. As of December 31, 2007, we have identified approximately $16.2 million of investments subject to this auction process for which there have been insufficient bidders at the scheduled rollover dates and held another approximately $33.0 million of these securities. As a result, we recorded an unrealized loss of $4.8 million in 2007. Subsequent to year end, of the approximately $33.0 million of these securities, approximately $8.5 million were sold at par, approximately $7.9 million had insufficient bidders and failed the reset process, and we believe the remaining approximately $16.6 million may be at risk of having this occur. While the investments are of a high credit quality and the rating of these securities has not been lowered, at this time we are uncertain when the liquidity issues associated with these investments will improve, when we will be able to exit these investments at their par value or whether we will incur any additional losses as a result of these investments. See Note 5 in “Notes to Consolidated Financial Statements.”

Most of our contracts may be canceled on short notice, so our revenue is not guaranteed.

Most of our contracts are cancelable on short notice, ranging from immediate cancellation to cancellation upon 180 days notice, even if we are not in default under the contract. Many of our contracts, including our service agreements, are periodically open to public bid. We may not be the successful bidder on our existing contracts that are re-bid. We also provide a significant portion of our services on a non-recurring, project-by-project basis. We could experience a reduction in our revenue, profitability and liquidity if:

	•		our customers cancel a significant number of contracts;

	•		we fail to win a significant number of our existing contracts upon re-bid; or

	•		we complete the required work under a significant number of our non-recurring projects and cannot replace them with similar projects.

We may not accurately estimate the costs associated with our services provided under fixed-price contracts which could impair our financial performance.

A substantial portion of our revenue is derived from master service agreements and other service agreements that are fixed price contracts. Under these contracts, we set the price of our services on a per unit or aggregate basis and assume the risk that the costs associated with our performance may be greater than we anticipated. In addition to master or other service agreements we enter into contracts that require installation or construction of specified units within an infrastructure system. Under those agreements, we have also contractually agreed to a price per unit. Profitability will be reduced if the actual costs to complete each unit exceed original estimates. We are also required to immediately recognize the full amount of any estimated costs on these projects if estimated costs to complete the remaining units for the projects exceed the revenue to be earned on such units.

Our profitability is therefore dependent upon our ability to accurately estimate the costs associated with our services. These costs may be affected by a variety of factors, such as lower than anticipated productivity, conditions at the work sites differing materially from what was anticipated at the time we bid on the contract and higher costs of materials and labor. Certain agreements or projects could have lower margins than anticipated or losses if actual costs for our contracts exceed our estimates, which could reduce our profitability and liquidity.

We recognize revenue for our installation/construction fixed price contracts using the percentage-of-completion method, therefore, variations of actual results from our assumptions may reduce our profitability.

We recognize revenue on long-term installation/construction fixed price contracts using the percentage-of-completion method. Under the percentage-of-completion method, we record revenue as work on the contract progresses. The cumulative amount of revenue recorded on a contract at a specified point in time is that percentage of total estimated revenue that incurred costs to date bear to estimated total contract costs. The percentage-of-completion method therefore relies on estimates of total expected contract costs. Contract revenue and total cost estimates are reviewed and revised periodically as the work progresses. Adjustments are reflected in contract revenue in the fiscal period when such estimates are revised. Estimates are based on management’s reasonable assumptions and experience, but are only estimates. Variation of actual results from estimates on a large project or on a number of smaller projects could be material. We immediately recognize the full amount of the estimated loss on a contract when our estimates indicate such a loss. Such adjustments and accrued losses could result in reduced profitability which could negatively impact our liquidity. For example, for the years ended December 31, 2007, 2006 and 2005, we incurred approximately $0.3 million, $6.8 million and $3.3 million, respectively, of losses on percentage-of-completion contracts. For the years ended December 31, 2006 and 2005, $6.5 million and $2.3 million, respectively, were included in loss from discontinued operations.

Amounts included in our backlog may not result in actual revenue or translate into profits.

Approximately 85.3% of our 18-month backlog at December 31, 2007 was comprised of master service agreements and other service agreements which do not require our customers to purchase a minimum amount of services and are cancelable on short notice. These backlog amounts are based on our estimates and therefore may not result in actual receipt of revenue in the originally anticipated period, or at all. In addition, contracts included in our backlog may not be profitable. We may experience variances in the realization of our backlog because of project delays or cancellations resulting from weather conditions, external market factors and economic factors beyond our control. If our backlog fails to materialize, we could experience a reduction in our revenue, profitability and liquidity.

Our business is seasonal and is affected by adverse weather conditions and the spending patterns of our customers, exposing us to variable quarterly results.

The budgetary years of many of our specialty infrastructure services customers end December 31. As a result, some of our customers reduce their expenditures and work order requests towards the end of the year. Adverse weather conditions, particularly during the winter season, also affect our ability to perform outdoor services in certain regions of the United States. As a result, we experience reduced revenue in the first and fourth quarters of each calendar year.

Natural catastrophes such as hurricanes in the United States could also have a negative impact on the economy overall and on our ability to perform outdoor services in affected regions or utilize equipment and crews stationed in those regions, which could result in a decline in profitability and liquidity.

We are self-insured against many potential liabilities.

Although we maintain insurance policies with respect to automobile liability, general liability, workers’ compensation and employee group health claims, those policies are subject to high deductibles, and we are self-insured up to the amount of the deductible. Since most claims against us do not exceed the deductibles under our insurance policies, we are effectively self-insured for substantially all claims. We actuarially determine any liabilities for unpaid claims and associated expenses, including incurred but not reported losses, and reflect those liabilities in our balance sheet as other current and non-current liabilities. The determination of such claims and expenses and the appropriateness of the liability is reviewed and updated quarterly. However, insurance liabilities are difficult to assess and estimate due to the many relevant factors, the effects of which are often unknown, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents not reported and the effectiveness of our safety program. If our insurance claims increase or costs exceed our estimates of insurance liabilities, we could experience a decline in profitability and liquidity.

Increases in our insurance premiums or collateral requirements could significantly reduce our profitability, liquidity and availability under our credit facility.

Because of factors such as increases in claims, projected significant increases in medical costs and wages, lost compensation and reductions in coverage, insurance carriers may be unwilling to continue to provide us with our current levels of coverage without a significant increase in insurance premiums or collateral requirements to cover our deductible obligations. An increase in premiums or collateral requirements could significantly reduce our profitability and liquidity as well as reduce availability under our revolving credit facility.

We may be unable to obtain sufficient bonding capacity to support certain service offerings and the need for performance and surety bonds may reduce our availability under our credit facility.

Some of our contracts require performance and surety bonds. Bonding capacity in the infrastructure industry has become increasingly difficult to obtain, and bonding companies are denying or restricting coverage to an increasing number of contractors. Companies that have been successful in renewing or obtaining coverage have sometimes been required to post additional collateral to secure the same amount of bonds which reduces availability under our credit facility. We may not be able to maintain a sufficient level of bonding capacity in the future, which could preclude us from being able to bid for certain contracts and successfully contract with certain customers. In addition, even if we are able to successfully renew or obtain performance or payment bonds in the future, we may be required to post letters of credit in connection with the bonds which would reduce availability under our credit facility. We reported net losses for the past six years. If we continue to incur net losses, our overall level of bonding capacity could be reduced.

We have agreed to keep certain liabilities related to the state Department of Transportation related projects and assets that were sold in February 2007.

In connection with the sale of our state Department of Transportation related projects and assets and the related settlement explained in “Item 1 — Business — Recent Developments”, we agreed to keep certain liabilities, mainly related to the cost to maintain and continue certain performance and payment bonds, certain obligations under leases between the parties and certain other litigation matters. We may also be unable to recover any losses we incur as a result of any third party claims to the extent any third parties seek payment from us directly and we are unable to recover such losses from the buyer pursuant to the indemnification obligations contained in the Revised Amended Agreement; including, in the event the buyer were financially unable to meet certain obligations, any losses resulting from creditor claims.

Under the terms of the Revised Amended Agreement, the buyer is no longer required to issue a standby letter of credit in our favor in February 2008 to cover any remaining exposure related to our bonded obligations. Instead, pursuant to the terms of the settlement agreement, the buyer entered into indemnity agreements directly with certain surety bonding companies in connection with our bonded obligations. Therefore, if the buyer is unable to meet its contractual obligations, the surety bonding company can seek its remedies under the indemnity agreement. If the surety bonding company, however, pays the amounts due under the bonds, the surety bonding company will seek reimbursement of such payment from us. Accordingly, we may incur losses in the future related to these contingent liabilities if the buyer does not complete the bonded contracts and we are unable to recover such losses from the buyer pursuant to the indemnification provisions contained in the Revised Amended Agreement. At December 31, 2007, we estimate that the cost to complete on the $161.8 million in performance and payment bonds related to these projects and assets was $8.4 million.

We may incur goodwill impairment charges in our reporting entities which could harm our profitability.

In accordance with Statement of Financial Accounting Standards, No. 142, “Goodwill and Other Intangible Assets”, or “SFAS No. 142”, we periodically review the carrying values of our goodwill to determine whether such carrying values exceed the fair market value. In the year ended December 31, 2005, we charged $11.5 million, against goodwill related to the decision to sell substantially all of our state Department of Transportation related projects and assets. In connection with our decision to sell substantially all our Canadian net assets, we wrote off goodwill associated with this entity in the amount of $0.4 million for the year ended December 31, 2007. We may incur additional impairment charges related to goodwill in any of our reporting entities in the future if the markets they serve or their business deteriorates.

We may incur restructuring charges which could reduce our profitability.

From time to time we review our operations in an effort to improve profitability. We could incur charges in the future as a result of:

	•		eliminating service offerings that no longer fit into our business strategy;

	•		reducing or eliminating services that do not produce adequate revenue or margin;

	•		reducing costs of businesses that provide adequate profit contributions but need margin improvements; and

	•		reviewing new business opportunities capable of utilizing our existing human and physical resources.

All charges related to restructuring would be reflected as operating expenses and could reduce our profitability.

Our revolving credit facility and senior notes impose restrictions on us which may prevent us from engaging in transactions that might benefit us, including responding to changing business and economic conditions or securing additional financing, if needed.

At December 31, 2006, we had $121.0 million in senior subordinated notes outstanding due February 2008 under an indenture. Since then we have issued $150.0 million aggregate principal amount of 7.625% senior notes due 2017, under a new indenture, the proceeds of which we used to redeem the senior subordinated notes due February 2008. We also have a $150.0 million revolving credit facility of which we had no outstanding cash draws at December 31, 2007. At December 31, 2007, the net availability under the credit facility was approximately $44.0 million which includes outstanding standby letters of credit aggregating $86.4 million. The terms of our indebtedness contain customary events of default and covenants that prohibit us from taking certain actions without satisfying certain financial tests or obtaining the consent of the lenders. The prohibited actions include, among other things:

	•		making investments and acquisitions in excess of specified amounts;

	•		incurring additional indebtedness in excess of specified amounts;

	•		paying cash dividends;

	•		creating certain liens against our assets;

	•		prepaying our other indebtedness, excluding the senior notes;

	•		engaging in certain mergers or combinations; and

	•		engaging in transactions that would result in a “change of control” (as defined in the credit facility and indenture).

Our credit facility provides that if our net borrowing base availability falls below $15.0 million we must comply with a minimum fixed charge coverage ratio. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations-Financial Condition, Liquidity and Capital Resources.” In the past, we have not been in compliance with certain financial covenants of our credit facility and have had to seek amendments or waivers from our lenders. Should we be unable to comply with the terms and covenants of our credit facility, we would be required to obtain further modifications of the facility or secure another source of financing to continue to operate our business. A default could result in the acceleration of either our obligations under the credit facility or under the indenture relating to the senior notes, or both. In addition, these covenants may prevent us from engaging in transactions that benefit us, including responding to changing business and economic conditions or securing additional financing, if needed. Our business is capital intensive and, to the extent we need additional financing, we may not be able to obtain such financing at all or on favorable terms, which may decrease our profitability and liquidity.

If we are unable to attract and retain qualified managers and skilled employees, we will be unable to operate efficiently which could reduce our revenue, profitability and liquidity.

Our business is labor intensive, and some of our operations experience a high rate of employee turnover. At times of low unemployment rates in the areas we serve, it can be difficult for us to find qualified and affordable personnel. We may be unable to hire and retain a sufficient skilled labor force necessary to support our operating requirements and growth strategy. Our labor expenses may increase as a result of a shortage in the supply of skilled personnel. If we are unable to hire employees with the requisite skills, we may also be forced to incur significant training expenses. Additionally, our business is managed by a number of key executive and operational officers and is dependent upon retaining and recruiting qualified management. Labor shortages, increased labor or training costs or the loss of key personnel could result in reduced revenue, profitability and liquidity.

Increases in the costs of fuel could reduce our operating margins.

The price of fuel needed to run our vehicles and equipment is unpredictable and fluctuates based on events outside our control, including geopolitical developments, supply and demand for oil and gas, actions by OPEC and other oil and gas producers, war and unrest in oil producing countries, regional production patterns and environmental concerns. Most of our contracts do not allow us to adjust our pricing. Accordingly, any increase in fuel costs could reduce our profitability and liquidity.

We may choose, or be required, to pay our subcontractors even if our customers do not pay, or delay paying, us for the related services.

We use subcontractors to perform portions of our services and to manage work flow. In some cases, we pay our subcontractors before our customers pay us for the related services. If we choose, or are required, to pay our subcontractors for work performed for customers who fail to pay, or delay paying us for the related work, we could experience a decrease in profitability and liquidity.

Our failure to comply with environmental laws could result in significant liabilities.

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.

We are currently engaged in litigation related to environmental liabilities in Coos Bay, Oregon. See “Item 3. Legal Proceedings.”

In addition, new environmental laws and regulations, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or leaks, or the imposition of new clean-up requirements could require us to incur significant costs or become the basis for new or increased liabilities that could negatively impact our profitability and liquidity.

Our failure to comply with the regulations of the U.S. Occupational Safety and Health Administration the U.S. Department of Transportation and other state and local agencies that oversee transportation and safety compliance could reduce our revenue, profitability and liquidity.

The Occupational Safety and Health Act of 1970, as amended, or “OSHA”, establishes certain employer responsibilities, including maintenance of a workplace free of recognized hazards likely to cause death or serious injury, compliance with standards promulgated by the Occupational Safety and Health Administration and various record keeping, disclosure and procedural requirements. Various standards, including standards for notices of hazards, safety in excavation and demolition work, may apply to our operations. We have incurred, and will continue to incur, capital and operating expenditures and other costs in the ordinary course of our business in complying with OSHA and other state and local laws and regulations.

We have, from time to time, received notice from the U.S. Department of Transportation that our motor carrier operations will be monitored and that the failure to improve our safety performance could result in suspension or revocation of vehicle registration privileges. If we cannot successfully resolve these issues, our ability to service our customers could be damaged which could lead to a reduction of our revenue, profitability and liquidity.

Our financial results are based, in part, upon estimates and assumptions that may differ from actual results.

In preparing our consolidated financial statements in conformity with accounting principles generally accepted in the United States, a number of estimates and assumptions are made by management that affect the amounts reported in the financial statements. These estimates and assumptions must be made because certain information that is used in the preparation of our financial statements is either dependent on future events or cannot be calculated with a high degree of precision from data available. In some cases, these estimates are particularly uncertain and we must exercise significant judgment. Estimates are primarily used in our assessment of the revenue recognition for costs and estimated earnings in excess of billings, allowance for doubtful accounts, accrued self-insured claims, valuation of goodwill and intangible assets, asset lives used in computing depreciation and amortization, including amortization of intangibles, and accounting for performance-based stock awards, income taxes (including net deferred tax assets), contingencies and litigation. Actual results could differ materially from the estimates and assumptions that we use, which could have a material adverse effect on our financial condition, results of operations and cash flows.

Our business is subject to hazards that could result in substantial liabilities and weaken our financial condition.

Construction projects undertaken by our employees involve exposure to electrical lines, pipelines carrying potentially explosive materials, heavy equipment, mechanical failures and adverse weather conditions. If serious accidents or fatalities occur, we may be restricted from bidding on certain work and certain existing contracts could be terminated. In addition, if our safety record were to deteriorate, our ability to bid on certain work could suffer. The occurrence of accidents in our business could result in significant liabilities or harm our ability to perform under our contracts or enter into new contracts with customers, which could reduce our revenue, profitability and liquidity.

Many of our communications customers are highly regulated and the addition of new regulations or changes to existing regulations may adversely impact their demand for our specialty contracting services and the profitability of those services.

Many of our communications customers are regulated by the Federal Communications Commission, or the “FCC”. The FCC may interpret the application of its regulations to communication companies in a manner that is different than the way such regulations are currently interpreted and may impose additional regulations. If existing or new regulations have an adverse affect on our communications customers and adversely impact the profitability of the services they provide, then demand for our specialty contracting services may be reduced.

Claims, lawsuits and proceedings could reduce our profitability and liquidity and weaken our financial condition.

We are subject to various claims, lawsuits and proceedings which arise in the ordinary course of business, including those described in “Item 3. Legal Proceeding.” Claimants may seek large damage awards and defending claims can involve significant costs. When appropriate, we establish reserves against these items that we believe to be adequate in the light of current information, legal advice and professional indemnity insurance coverage, and we adjust such reserves from time to time according to case developments. If our reserves are inadequate, or if in the future our insurance coverage proves to be inadequate or unavailable or there is an increase in liabilities for which we self-insure, we could experience a reduction in our profitability and liquidity. An adverse determination on any such claim, lawsuit or proceeding could have a material adverse effect on our business, financial condition or results of operations. In addition, claims, lawsuits and proceedings may harm our reputation or divert management resources away from operating our business. See “Item 3. Legal Proceedings.”

Acquisitions involve risks that could result in a reduction of our profitability and liquidity.

We have made, and in the future plan to make, strategic acquisitions. However, we may not be able to identify suitable acquisition opportunities or may be unable to obtain the consent of our lenders and therefore not be able to complete such acquisitions. We may pay for acquisitions with our common stock which may dilute your investment in our common stock or decide to pursue acquisitions that investors may not agree with. In addition, acquisitions may expose us to operational challenges and risks, including:

	•		the ability to profitably manage additional businesses or successfully integrate the acquired business operations and financial reporting and accounting control systems into our business;

	•		increased indebtedness and contingent purchase price obligations associated with an acquisition;

	•		the ability to fund cash flow shortages that may occur if anticipated revenue is not realized or is delayed, whether by general economic or market conditions or unforeseen internal difficulties;

	•		the availability of funding sufficient to meet increased capital needs;

	•		diversion of management’s attention; and

	•		the ability to hire qualified personnel required for expanded operations.

A failure to successfully manage the operational challenges and risks associated with or resulting from acquisitions could result in a reduction of our profitability and liquidity. Borrowings associated with these acquisitions may also result in higher levels of indebtedness which could impact our ability to service our debt within the scheduled repayment terms.

We may incur significant costs as a result of our lawsuit with our excess insurance carrier.

In the second quarter of 2004, several complaints for a purported securities class action were filed against us and certain of our officers. We have settled these actions without payments to the plaintiffs by us. As part of the settlement, our excess insurance carrier has retained its rights to seek up to $2.0 million in reimbursement from us based on its claim that notice was not properly given under the policy. We may be unable to successfully resolve this dispute without incurring significant expense. See “Item 3. Legal Proceedings.”

Risks Related to Our Company and Our Common Stock

The market price of our common stock has been, and may continue to be, highly volatile.

From 2001 to 2003, for example, our common stock fluctuated from a high of $24.75 per share in the first quarter of 2001 to a low of $1.31 per share in the first quarter of 2003. During 2006 and 2007, our common stock fluctuated from a high of $16.25 per share to a low of $8.68 per share. We may continue to experience significant volatility in the market price of our common stock. See “Item 5. Market Information for the Registrant’s Common Equity, Related Shareholder Matters and Issuer Purchases of Equity Securities.”

Numerous factors could have a significant effect on the price of our common stock, including:

	•		announcements of fluctuations in our operating results or the operating results of one of our competitors;

	•		future sales of our common stock or other securities;

	•		announcements of new contracts or customers by us or one of our competitors;

	•		market conditions for providers of services to communications companies, utilities and government;

	•		changes in recommendations or earnings estimates by securities analysts; and

	•		announcements of acquisitions by us or one of our competitors.

In addition, the stock market has experienced significant price and volume fluctuations in recent years that have sometimes been unrelated or disproportionate to the operating performance of companies. The market price for our common stock has been volatile and such volatility could cause the market price of our common stock to decrease and cause you to lose some or all of your investment in our common stock.

A small number of our existing shareholders have the ability to influence major corporate decisions.

Jorge Mas, our Chairman, Jose Mas, our CEO, and other members of the Mas family who are employed by MasTec, beneficially own approximately 32.7% of the outstanding shares of our common stock as of February 25, 2008. Accordingly, they are in a position to influence:

	•		the vote of most matters submitted to our shareholders, including any merger, consolidation or sale of all or substantially all of our assets;

	•		the nomination of individuals to our Board of Directors; and

	•		a change in our control.

These factors may discourage, delay or prevent a takeover attempt that you might consider in your best interest or that might result in you receiving a premium for your common stock.

Our articles of incorporation and certain provisions of Florida law contain anti-takeover provisions that may make it more difficult to effect a change in our control.

Certain provisions of our articles of incorporation and bylaws and the Florida Business Corporation Act could delay or prevent an acquisition or change in control and the replacement of our incumbent directors and management, even if doing so might be beneficial to our shareholders by providing them with the opportunity to sell their shares possibly at a premium over the then market price of our common stock. For example, our Board of Directors is divided into three classes. At any annual meeting of our shareholders, our shareholders only have the right to appoint approximately one-third of the directors on our Board of Directors. Consequently, it will take at least two annual shareholder meetings to effect a change in control of our Board of Directors, which may discourage hostile takeover bids. In addition, our articles of incorporation authorize our Board of Directors, without further shareholder approval, to issue preferred stock. The issuance of preferred stock could also dilute the voting power of the holders of our common stock, including by the grant of voting control to others, which could delay or prevent an acquisition or change in control.

Item 1B.Unresolved Staff Comments

None.

Item 2.Properties

Our corporate headquarters is a 24,000 square foot leased facility located in Coral Gables, Florida.

As of December 31, 2007, our operations were conducted from approximately 200 locations. None of our facilities in these locations is material to our operations because most of our services are performed on customers’ premises or on public rights of way and because suitable alternative locations are available in substantially all areas where we currently conduct business.

We also own property and equipment that, at December 31, 2007, had a net book value of $81.9 million. This property and equipment includes land, buildings, vans, trucks, tractors, trailers, bucket trucks, backhoes, bulldozers, directional boring machines, digger derricks, cranes, networks, computers, computer software, office and other equipment. Our equipment is acquired from various third-party vendors, none of which we depend upon, and we did not experience any difficulties in obtaining desired equipment in 2007.

Item 3.Legal Proceedings

Change in Strategy Regarding Litigation and Other Disputes

In the third quarter of 2007, our senior management performed a reassessment of our major legal cases, claims and other disputes, including disputes involving amounts due us, and decided to accelerate the closure of a number of these matters, particularly older legal cases, claims and disputes from the years 2001 through 2005, which generally do not involve current customers. In part, this decision was driven by a desire to reduce the high levels of legal expense and related costs that we have incurred in recent years, and to reduce the amount of management’s time devoted to litigation matters and other claims and disputes. While we will attempt to accelerate the closure of these matters, we will only do so if we believe such resolution is in the best interests of MasTec and its shareholders.

Legacy Litigation

MasTec is subject to significant outstanding litigation, primarily dating from the period 2001 through 2005.

In 2005, former employees filed a Fair Labor Standards Act (“FLSA”) collective action against MasTec in the Federal District Court in Tampa, Florida, alleging failure to pay overtime wages as required under the FLSA. While MasTec denies the allegations underlying the lawsuit, in October 2007 we agreed to a settlement to avoid significant legal fees, the uncertainty of a jury trial, other expenses and management time that would have to be devoted to protracted litigation. The settlement covers MasTec’s current and former install-to-the home employees who were employed by MasTec from October 2001 through September 2007 in California, Florida, Georgia, Maryland, New Jersey, New Mexico, North Carolina, South Carolina, Texas and Virginia. The gross amount of the settlement is up to $12.6 million, and is subject to court approval. This amount represents the maximum payout, assuming 100% opt-in by all potential members of the purported class.

We contracted to construct a natural gas pipeline for Coos County, Oregon in 2003. Construction work on the pipeline ceased in December 2003 after Coos County refused payment due us on regular contract invoices of $6.3 million and refused to process change orders submitted after November 2003 for additional work. In February 2004, we declared a breach of contract and brought an action for breach of contract against Coos County in Federal District Court in Oregon, seeking payment for work done and interest. In April 2004, Coos County announced it was terminating the contract and seeking another company to complete the project. Coos County subsequently counterclaimed against us in the Federal District Court action seeking damages in excess of $15 million for breach of contract for alleged failures to properly construct the pipeline and for alleged environmental and labor law violations, and other causes. The amount of revenue recognized on the Coos County project that remained uncollected in accounts receivable on the December 31, 2007 balance sheet amounted to $6.3 million representing amounts due to us on normal progress payment invoices submitted under the contract. In February 2008, we entered into a tentative agreement to settle our dispute with Coos County, which provides for a $4.35 million payment to Coos County in June 1, 2008 and a $4.35 million payment to Coos County on June 1, 2009 with 3% interest accruing beginning June 1, 2008. The tentative agreement is subject to the negotiation and approval of a definitive settlement agreement and MasTec not being penalized greater than $1.5 million in the Corps of Engineers case described below. We cannot assure you that these conditions will be met.

In connection with the Coos County pipeline project, the United States Army Corps of Engineers, or “Corps of Engineers”, and the Oregon Department of Environmental Quality issued cease and desist orders and notices of non-compliance to Coos County and to us with respect to the project. While we do not agree that the notices were appropriate or justified, we have cooperated with the Corps of Engineers and the Oregon Division of State Land, Department of Environmental Quality to mitigate any adverse impact as a result of construction. On March 30, 2006, the Corps of Engineers brought a complaint in a federal district court against us and Coos County and are seeking damages in excess of $16 million. The matter went to trial in February 2008 and we are awaiting a verdict.

In June 2005, we posted a $2.3 million bond in order to pursue the appeal of a $2.0 million final judgment entered against us for damages plus attorney’s fees resulting from a break in a Citgo pipeline that occurred in 1999. We are seeking a new trial and a reduction in the amount of damages awarded. We will continue to contest this matter in the appellate court, and on subsequent retrial, if any.

During 2003 and 2004, we provided services to MSE Power Systems on five separate projects in Pennsylvania, New York and Georgia, with invoices in excess of $8 million in dispute. In 2004, we filed suit against MSE seeking payment. To date, we have recovered $1.3 million from MSE in settlement on three of these projects and are seeking additional amounts owed us. An arbitration was held in August 2007 and in January 2008 we were awarded a $2.65 million judgment in connection therewith.

In November 2004, MasTec entered into, and bonded, a conditional $2.6 million settlement of litigation brought for subcontract work done in 2001 by Hugh O’Kane Electric for MasTec on a telecommunication project for Telergy in New York. Telergy is in bankruptcy and did not pay MasTec for this work. The settlement was conditioned upon the resolution of all of the Court proceedings including appeals. MasTec filed an appeal seeking to enforce contractual terms which relieved MasTec of its obligation to pay Hugh O’Kane when MasTec was not paid by Telergy. New York’s appellate level court upheld the enforceability of the terms of MasTec’s contract, but remanded the case to the trial court to determine whether there were factual issues that prevented MasTec from using the contractual provision as a defense. The trial court found that factual issues prevented MasTec from using the contractual provision as a defense and MasTec appealed. The appellate court upheld the trial courts ruling and MasTec requested a rehearing, which was denied.

Similar litigation was filed against MasTec by other subcontractors performing work in 2001 on the Telergy project. In a related matter, MasTec filed suit against Con Edison in May 2002, alleging that Con Edison directly interfered with MasTec’s work for Telergy, and that this interference resulted in the bankruptcy of Telergy and resulted in Con Edison obtaining MasTec’s work on the Telergy project without paying for it. MasTec seeks in excess of $40 million from Con Edison.

In April 2006, we settled, without payment to the plaintiffs by us, several complaints for purported securities class actions that were filed against us and certain officers in the second quarter of 2004. As part of the settlement, our excess insurance carrier has retained the rights to seek reimbursement of up to $2.0 million from us based on its claim that notice was not properly given under the policy. We are also seeking reimbursement of expenses incurred by us which we believe are reimbursable by our excess insurance carrier. We believe the claims of the excess insurance carrier are without merit and plan to continue vigorously pursuing this action. Although a district court ruled in March 2007 that there is no coverage provided under the excess policy, we disagree and have appealed. We are also pursuing claims against the insurance broker for any losses arising from the same issue involving notice.

In February 2008, we were notified in writing by the SEC staff that its formal investigation related to the restatement of our financial statements in 2001 through 2003 has been completed and that it does not intend to recommend an enforcement action.

We provided telecommunication infrastructure services to Adesta Communications, Inc. in 2000 and 2001. Adesta filed for bankruptcy in 2001. At December 31, 2007 we were seeking to recover amounts in excess of $4 million from the Adesta bankruptcy trustee from the proceeds of the sale of Adesta’s assets. Based on our understanding of the current status of the bankruptcy trustee’s sales negotiations with respect to these assets, we have reflected $1.3 million in other current assets on our consolidated balance sheet at December 31, 2007 related to Adesta.

2007, the Court decided to close the investigation and issued an order allowing the trial phase against the former officers of MasTec, Inc. to proceed. The order does not name MasTec, Inc. as a potentially liable party. The union has alleged Sintel and its creditors were damaged in the approximate amount of 269 million euros ($396 million at December 31, 2007). The order is subject to appeal by several of the parties. To date, no actions have been taken by the Court against us or any of the named individuals. Our directors’ and officers’ insurance carrier has reimbursed us all of our legal fees to date and agreed to fund legal expenses for the remainder of the litigation under a reservation of rights. The amount of loss, if any, relating to this matter cannot presently be determined.

In October 2003, a MasTec subsidiary filed a lawsuit in a New York state court against Inepar Industria e Construcoes or “Inepar”, its Brazilian joint venture partner. MasTec sued Inepar for breach of contract arising out of Inepar’s failure to indemnify MasTec for claims resulting from numerous misrepresentations made by Inepar. Inepar subsequently failed to answer MasTec’s complaint and MasTec sought a default judgment. In September 2006, the state court entered a judgment in favor of MasTec and against Inepar in the amount of $58.4 million. MasTec has commenced collections efforts. Due to the uncertainty of the ongoing collection process, we have accounted for the amounts related to this judgment in our favor as a gain contingency and have not reflected these amounts in our financial statements.

In December 2004, we brought an action against NextiraOne Federal in the Federal Court in Eastern District of Virginia, to recover payment for services rendered in connection with a Federal Department of Defense project on a network wiring contract. Our network services are now a discontinued operation. NextiraOne counterclaimed for offsets and remediation. On May 5, 2006, the court ruled that we failed to establish an entitlement to recover damages for contract work done, and that NextiraOne Federal failed to establish an entitlement to recover costs of alleged offsets and costs of remediation. We appealed, but the appellate court affirmed the lower court’s ruling.

Other Litigation, Claims and Disputes.

In addition to the matters discussed above, we are also subject to a variety of legal cases, claims and other disputes that arise from time to time in the ordinary course of our business.

Financial Statement Impact.

Primarily as a result of the change in strategy noted above, we entered into settlement negotiations on several of these legal cases, claims and other disputes, including disputes involving amounts due us, reached settlement on the FLSA matter discussed above and on other disputes, and authorized settlement on a number of other matters, including certain accounts receivable for which we had been pursuing collection via negotiation or via the legal process. As a result of these negotiations and actual or anticipated settlements (including FLSA and Coos County), and other developments, we recorded charges totaling $39.1 million for the actual or anticipated settlement of litigation, claims and other disputes in the nine months ended September 30, 2007 and $0.2 million in the three months ended December 31, 2007. Accrued aggregate liabilities related to the matters discussed above amounted to approximately $24.9 million at December 31, 2007 which is included in other current liabilities. Our allowance for doubtful accounts and other asset valuation accounts related to the matters discussed above amounted to $9.7 million and $4.4 million, respectively, at December 31, 2007.

Although we believe that we have gone through a thorough review of these legacy and other matters and have developed what we believe are reasonable estimates for settling the legacy legal cases, claims and other disputes, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future as facts and circumstances change. We have incurred substantial costs in connection with these claims and will continue to do so until there is a resolution of these matters. We cannot assure you that a favorable outcome will be reached in any of these cases. If we are not able to settle these cases at the amounts estimated, or if we are subject to an unfavorable trial outcome or other final resolution on these matters, there exists the possibility of a material adverse impact on the Company’s financial position and on the results of operations for the period in which the effect becomes reasonably estimable. See “Item 1A — Risk Factors — Risks Related to Our Business — Claims, lawsuits and proceedings could reduce profitability and liquidity and weaken our financial conditions.”

Dividends.We have never paid any cash dividends and do not anticipate paying any cash dividends in the foreseeable future. Instead we intend to retain any future earnings for reinvestment. Our Board of Directors will make any future determination as to the payment of dividends at its discretion, and its determination will depend upon our operating results, financial condition and capital requirements, general business conditions and such other factors that the board of directors considers relevant. In addition, our credit agreements prohibit us from paying cash dividends or making other distributions on our common stock without the prior consent of the lender and the indenture governing our senior notes contains covenants that restrict our ability to make certain payments including the payment of dividends. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Financial Condition, Liquidity and Capital Resources.”

Unregistered Sales of Equity Securities and Proceeds. On December 20, 2007, we acquired certain assets of Power Partners 1979, LLC, for a purchase price of $5.5 million in cash and assumed liabilities of $1.1 million and agreed to pay the seller and earnout based on performance through the fifth anniversary of the closing date. We may, at our option, issue up to 660,000 shares of our common stock to the seller of this business in connection with the earnout for this acquisition. We have offered to potentially issue these shares to the sellers in reliance on the exemption from registration provided by Section 4(2) of the Securities Act of 1933, as amended.

Purchases of MasTec Stock.We did not repurchase any shares of our common stock during the year ended December 31, 2007.

Item 7.Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our historical consolidated financial statements and related notes thereto in “Item 8. Financial Statements and Supplementary Data.” The discussion below contains forward-looking statements that are based upon our current expectations and are subject to uncertainty and changes in circumstances. Actual results may differ materially from these expectations due to inaccurate assumptions and known or unknown risks and uncertainties, including those identified in “Cautionary Statement Regarding Forward-Looking Statements” and “Item 1A. Risk Factors.”

Overview

We are a leading specialty contractor operating mainly throughout the United States and across a range of industries. Our core activities are the building, installation, maintenance and upgrade of communications and utility infrastructure. Our primary customers are in the following industries: communications (including satellite television and cable television), utilities and governments. We provide similar infrastructure services across the industries we serve. Our customers rely on us to build and maintain infrastructure and networks that are critical to their transport and delivery of voice, video and data communications, electricity and other energy resources.

We, or our predecessor companies, have been in business for over 70 years. We offer all of our services under the MasTec^® service mark and operate through a network of approximately 200 locations and 8,240 employees as of December 31, 2007. Providing services to the communication industries, utility industries and government sectors, we have consistently ranked among the top specialty contractors by Engineering News-Record.

On January 31, 2007, we issued $150.0 million of 7.625% senior notes due February 2017. On March 2, 2007, we used $121.8 million of the proceeds from the senior note offering to redeem all of our remaining 7.75% senior subordinated notes plus interest.

We also amended our credit facility effective June 30, 2007, which extended the expiration date of the credit facility from May 10, 2010 to May 10, 2012. The amendment also added an accordion feature which allows us to request an increase in the maximum amount borrowed under the credit facility from $150 million to $200 million, if certain criteria under the credit facility is met, reduced the interest rate margin applied to borrowings and increased the maximum available amount we can borrow at any given time, among other things.

In February 2007, we acquired the remaining 51% equity interest in an investment in which we previously owned a 49% interest. During 2007 we also acquired an entity specializing in the construction and maintenance of transmission and distribution utility systems, substation and storm restoration in several northern states and acquired certain assets and assumed certain liabilities of an electrical utility contractor specializing in wind farm construction. Finally, in 2007 and 2008 we acquired the remaining minority ownership interest in GlobeTec Construction, LLC (“GlobeTec”).

Effective February 1, 2007, we sold our state Department of Transportation related projects and assets. We agreed to keep certain assets and liabilities. On January 24, 2008, we entered into a settlement agreement with the buyer of our state Department of Transportation projects and assets to settle previously disclosed warranty, indemnification and other claims primarily relating to work we had performed on projects we sold.

In the third quarter of 2007, we performed a reassessment of our major legal cases, claims and other disputes, including disputes involving amounts due us, and decided to accelerate the closure of a number of these matters, particularly older legal cases, claims and disputes from the years 2001to 2005, which generally do not involve current customers. In part, this decision was driven by a desire to reduce the high levels of legal expense and related costs that we have incurred in recent years, and to reduce the amount of management’s time devoted to litigation matters and other claims and disputes. While we will attempt to accelerate the closure of these matters, we will only do so if we believe such resolution is in the best interests of MasTec and its shareholders. As a result of the change in strategy and actual or anticipated settlements, and other developments, we recorded charges totaling $39.1 million for the actual or anticipated settlement of litigation, claims and other disputes in the three months ended September 30, 2007 and $0.2 million in the three months ended December 31, 2007.

Revenue

We provide services to our customers which are companies in the communications and utilities industries as well as government customers.

Revenue for customers in these industries is as follows:


	Year Ended December 31,
	2007		2006		2005
	(In thousands)
Communications	$	769,611	$	684,217	$	610,787
Utilities		217,385		217,947		183,889
Government		50,783		38,257		43,987

	$	1,037,779	$	940,421	$	838,663

A significant portion of our revenue is derived from projects performed under service agreements. We also provide services under master service agreements which are generally multi-year agreements. Certain of our master service agreements are exclusive up to a specified dollar amount per work order for each defined geographic area. Work performed under master service and other agreements is typically generated by work orders, each of which is performed for a fixed fee. The majority of these services typically are of a maintenance nature and to a lesser extent upgrade services. These master service agreements and other service agreements are frequently awarded on a competitive bid basis, although customers are sometimes willing to negotiate contract extensions beyond their original terms without re-bidding. Our master service agreements and other service agreements have various terms, depending upon the nature of the services provided and are typically subject to termination on short notice.

The remainder of our work is generated pursuant to contracts for specific installation/construction projects or jobs that may require the construction and installation of specified units within an infrastructure system or an entire infrastructure system. Customers are billed with varying frequency: weekly, monthly or upon attaining specific milestones. Such contracts generally include retainage provisions under which 2% to 15% of the contract price is withheld from us until the work has been completed and accepted by the customer.

Revenue by type of contract is as follows:


	Year Ended December 31,
	2007		2006		2005
	(In thousands)
Master service and other service agreements	$	750,462	$	698,867	$	576,311
Installation/construction projects agreements		287,317		241,554		262,352

	$	1,037,779	$	940,421	$	838,663

Costs of Revenue

Our costs of revenue include the costs of providing services or completing the projects under our contracts including operations payroll and benefits, fuel, subcontractor costs, equipment rental, materials not provided by our customers, and insurance. Profitability will be reduced if the actual costs to complete each unit exceed original estimates on fixed price service agreements. We also immediately recognize the full amount of any estimated loss on fixed fee projects if estimated costs to complete the remaining units for the project exceed the revenue to be received from such units.

Our customers generally supply materials such as cable, conduit and telephone equipment. Customer furnished materials are not included in revenue and cost of sales due to all materials being purchased by the customer. The customer determines the specifications of the materials that are to be utilized to perform installation/construction services. We are only responsible for the performance of the installation/construction services and not the materials for any contract that includes customer furnished materials nor do we have any risk associated with customer furnished materials. Our customers retain the financial and performance risk of all customer furnished materials.

General and Administrative Expenses

General and administrative expenses include all costs of our management and administrative personnel, provisions for bad debts, rent, utilities, travel, business development efforts and back office administration such as financial services, insurance, administration, professional costs and clerical and administrative overhead.

Discontinued Operations

Effective February 2007, we sold the state Department of Transportation related projects and net assets. As a result of this sale, we recorded impairment charges totaling $2.9 million and $44.5 million during the years ended December 31, 2007 and 2006, respectively. On January 24, 2008, we entered into a settlement with the buyer of our state Department of Transportation related projects and assets, to settle previously disclosed warranty, indemnification and other claims primarily relating to work we had performed on the projects which were sold. As a result of the settlement, we have recorded a charge of $6.0 million which is reflected in our loss from discontinued operations for the year ended December 31, 2007.

In April 2007, we sold substantially all of our Canadian operations for approximately $1.0 million. In addition, we reviewed the carrying value of the net assets related to our Canadian operations. During the year ended December 31, 2007, we wrote-off $0.4 million in goodwill in connection with our decision to sell substantially all of our Canadian net assets. In addition, we recorded a non-cash impairment charge of approximately $0.6 million. See Note 11 “Discontinued Operations” in Notes to Consolidated Financial Statements. The financial information for all periods presented in this annual report on Form 10-K reflects the above operations as discontinued operations.

Financial Metrics

Members of our senior management team regularly review key performance metrics and the status of operating initiatives within our business. These key performance indicators include:

	•		revenue and profitability on an individual project basis;

	•		monthly, quarterly and annual changes in revenue on an individual project basis;

	•		costs of revenue, and general and administrative expenses as percentages of revenue;

	•		number of vehicles and equipment per employee;

	•		days sales outstanding;

	•		interest and debt service coverage ratios;

	•		safety results and productivity; and

	•		customer service metrics on an individual project basis.

We analyze this information periodically through operating reviews which include detailed discussions, proposed investments in new business opportunities or property and equipment and integration and cost reduction efforts. Measuring these key performance indicators is an important tool that our management uses to make operational decisions. These tools enable our management to make more informed, better and quicker decisions about the allocation of costs and resources which, we believe, can help us improve our performance.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, intangible assets, reserves and accruals, impairment of assets, income taxes, insurance reserves and litigation and contingencies. We base our estimates on historical

experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis of making judgments about the carrying values of assets and liabilities, that are not readily apparent from other sources. Actual results may differ from these estimates if conditions change or if certain key assumptions used in making these estimates ultimately prove to be materially incorrect.

We believe the following critical accounting policies involve our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

Revenue and related costs for master and other service agreements billed on a time and materials basis are recognized as the services are rendered. There are also master service agreements that are billed on a fixed fee basis. Under our fixed fee master service and similar type service agreements, we furnish various specified units of service for a separate fixed price per unit of service. For service agreements on a fixed fee basis, profitability will be reduced if the actual costs to complete each unit exceed original estimates.

In addition to master and other service agreements we enter into contracts that require the installation or construction of specified units within an infrastructure system. Under these contracts, revenue is recognized at the contractually agreed upon price as the units are completed and delivered. Our profitability will be reduced if the actual costs to complete each unit exceed our original estimates. We are also required to immediately recognize the full amount of any estimated loss on these projects if estimated costs to complete the remaining units for the project exceed the revenue to be earned on such units.

We also enter into fixed price, long-term installation/construction contracts that primarily require the construction and installation of an entire infrastructure system. We recognize revenue and related costs as work progresses on fixed price long-term contracts using the percentage-of-completion method, which relies on contract revenue and estimates of total expected costs. We estimate total project costs and profit to be earned on each fixed-price, long-term contract. We follow this method since reasonably dependable estimates of the revenue and costs applicable to various stages of a contract can be made. Under the percentage-of-completion method, we record revenue and recognize profit or loss as work on the contract progresses. The cumulative amount of revenue recorded on a contract at a specified point in time is that percentage of total estimated revenue that incurred costs to date bear to estimated total contract costs. We recognize the full amount of any estimated loss on a contract at the time our estimates indicate such a loss.

Our customers generally supply materials such as cable, conduit and telephone equipment. Customer furnished materials are not included in revenue and cost of sales as all materials are purchased by the customer. The customer determines the specification of the materials that are to be utilized to perform installation/construction services. We are only responsible for the performance of the installation/construction services and not the materials for any contract that includes customer furnished materials and we do not have any risk associated with customer furnished materials. Our customers retain the financial and performance risk of all customer furnished materials.

Allowance for Doubtful Accounts

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. Management analyzes past due balances based on invoice date, historical bad debt experience, customer concentrations, customer credit-worthiness, customer financial condition and credit reports, the availability of mechanics’ and other liens, the existence of payment bonds and other sources of payment, and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. We review the adequacy of reserves for doubtful accounts on a quarterly basis. If our estimates of the collectability of accounts receivable change, adjustments to the allowance for doubtful accounts may be required, which could reduce our profitability.

Our estimates for our allowance for doubtful accounts are subject to significant change during times of economic weakness or uncertainty in either the overall U.S. economy or the industries we serve, and our loss experience has increased during such times.

We recorded total provisions against earnings for doubtful accounts of $17.6 million, $10.0 million and $4.9 million, for the years ended December 31, 2007, 2006 and 2005, respectively, of which $14.1 million, $7.9 million and $3.7 million, respectively, resulted from anticipated legal settlement and discontinued operations in our consolidated statements of operations for those periods.

Inventories

Inventories consist of materials and supplies for construction and install to the home projects, and are typically purchased on a project-by-project basis. Inventories are valued at the lower of cost (using the specific identification method) or market. Construction projects are completed pursuant to customer specifications. The loss of the customer or the cancellation of the project could result in an impairment of the value of materials purchased for that customer or project. Technological or market changes can also render certain materials obsolete. Allowances for inventory obsolescence are determined based upon the specific facts and circumstances for each project and market conditions. During the year ended December 31, 2007, we recorded no inventory obsolescence provisions. During the years ended 2006 and 2005, we recorded inventory obsolescence provisions of $0.6 million and $1.0 million, respectively, of which $0.6 million and $0.3 million, respectively, are included in loss from discontinued operations in the consolidated statements of operations.

Depreciation and Amortization

We depreciate our property and equipment over estimated useful lives using the straight-line method. We periodically review changes in technology and industry conditions, asset retirement activity and salvage values to determine adjustments to estimated remaining useful lives and depreciation rates.

Securities Available-for-Sale

We account for securities available-for-sale in accordance with the provisions of SFAS No. 115, “Accounting For Certain Debt and Equity Securities.” Securities available-for-sale are recorded at fair value, and temporary unrealized holding gains and losses are recorded, as a separate component of accumulated other comprehensive income (loss). Unrealized losses are charged against net earnings when a decline in fair value is determined to be other-than-temporary. In accordance with FSP FAS 115-1 and 124-1,“The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments,”we review several factors to determine whether a loss is other-than-temporary. These factors include but are not limited to: i) the length of time a security is in an unrealized loss position, ii) the extent to which fair value is less than cost, iii) the financial condition and near term prospects of the issuer and, iv) our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Auction-rate securities represent interests in collateralized debt obligations, student loans, taxable municipal bonds and similar securities. Liquidity for these auction-rate securities is typically provided by an auction process that resets the applicable interest rate at pre-determined intervals, usually every 7, 28, or 35 days. Due to the short interest rate reset period and expected liquidity, we have recorded auction-rate securities as current securities available for sale. As of December 31, 2007, we held approximately $16.2 million of high credit quality auction-rate securities which had experienced a failed reset process and were deemed to have experienced a temporary decline in fair value, and held another approximately $33.0 million of these securities. We have recorded approximately $4.8 million of unrealized losses related to the auction securities as of December 31, 2007. Subsequent to year end, of the approximately $33.0 million of these securities, $8.5 million were sold at par, approximately $7.9 million had insufficient bidders and failed the reset process, and we believe the remaining approximately $16.6 million may also be temporarily at risk of having this occur.

Valuation of Long-Lived Assets

We review long-lived assets, consisting primarily of property and equipment and intangible assets with finite lives, for impairment in accordance with Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”). In analyzing potential impairment, we use projections of future discounted cash flows from the assets. These projections are based on our view of growth rates for the related business, anticipated future economic conditions and the appropriate discount rates relative to risk and estimates of residual values. We believe that our estimates are consistent with assumptions that marketplace participants would use in their estimates of fair value. In addition, due to the decision to dispose of our state Department of Transportation projects and assets, we evaluated long-lived assets for these operations under SFAS No. 144 based on projections of future discounted cash flows from these assets in 2006 and an estimated selling price for the assets held for sale.

Valuation of Goodwill and Intangible Assets

In accordance with SFAS No. 142, we conduct, on at least an annual basis, a review of our reporting units to determine whether the carrying values of goodwill exceed the fair market value using a discounted cash flow methodology for each unit. Should this be the case, the value of our goodwill may be impaired and written down.

In connection with the commitment to sell sale of substantially all of our state Department of Transportation related projects and assets, we wrote off goodwill associated with this entity in the amount of $11.5 million during the year ended December 31, 2005. In connection with our decision to sell substantially all of our Canadian operations, we wrote off goodwill associated with this entity in amount of $0.4 million for the year ended December 31, 2007.

We could record additional impairment losses if, in the future, profitability and cash flows of our reporting entities decline to the point where the carrying value of those units exceed their market value. See “Item 1A. Risk Factors — We may incur goodwill impairment charges in our reporting entities which could harm our profitability.”

Insurance Reserves

We presently maintain insurance policies subject to per claim deductibles of $1 million for our workers’ compensation policy, $2 million for our general liability policy and $3 million for our automobile liability policy. We have excess umbrella coverages up to $100 million per claim and in the aggregate. We also maintain an insurance policy with respect to employee group health claims subject to per claim deductibles of $300,000 after satisfying an annual deductible of $100,000. We actuarially determine any liabilities for unpaid claims and associated expenses, including incurred but not reported losses, and reflect those liabilities in our balance sheet as other current and non-current liabilities. The determination of such claims and expenses and the appropriateness of the related liability is reviewed and updated quarterly. However, insurance liabilities are difficult to assess and estimate due to the many relevant factors, the effects of which are often unknown, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents not reported and the effectiveness of our safety program. We are working with our insurance carriers to resolve claims more quickly in an effort to reduce our exposure. We are also attempting to accelerate the claims process where possible so that amounts incurred can be reported rather than estimated. In addition, known amounts for claims that are in the process of being settled, but have been paid in periods subsequent to those being reported, are booked in the reporting period. Our accruals are based upon known facts, historical trends and our reasonable estimate of future expenses and we believe such accruals to be adequate.

We are periodically required to post letters of credit and provide cash collateral to our insurance carriers. As of December 31, 2007 and 2006, such letters of credit amounted to $64.8 million and $66.2 million, respectively, and cash collateral posted amounted to $3.3 million and $6.6 million, respectively, which is included in other assets.

Income Taxes

We record income taxes using the liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequence of temporary differences between the financial statement and income tax bases of our assets and liabilities. We estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our tax exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. The recording of a net deferred tax asset assumes the realization of such asset in the future. Otherwise a valuation allowance must be recorded to reduce this asset to its net realizable value. We consider future pretax income and ongoing prudent and feasible tax planning strategies in assessing the need for such a valuation allowance. In the event that we determine that we may not be able to realize all or part of the net deferred tax asset in the future, a valuation allowance for the deferred tax asset is charged against income in the period such determination is made.

As a result of our operating losses, we have recorded valuation allowances aggregating $47.9 million and $49.2 million as of December 31, 2007 and 2006, respectively, to reduce certain of our net deferred federal, foreign and state tax assets to their estimated net realizable value. We anticipate that we will generate sufficient pretax income in the future to realize our remaining deferred tax assets. In the event that our future pretax operating income is insufficient for us to use our deferred tax assets, we have based our determination that the deferred tax assets are still realizable based on feasible tax planning strategies that are available to us. At December 31, 2007, we have approximately $176 million of net operating loss carryforwards for U.S. federal income tax purposes that expire beginning in 2022. We also have net operating loss carryforwards for U.S. state and local purposes that expire from 2007 to 2026. We have unrealized excess tax benefit of approximately $1.7 million, that when realized, will increase capital surplus.

Litigation and Contingencies

Litigation and contingencies are reflected in our consolidated financial statements based on our assessments, along with legal counsel, of the expected outcome of such litigation or expected resolution of such contingency. An accrual is made when the loss of such contingency is probable and estimable. If the final outcome of such litigation and contingencies differs significantly from our current expectations, such outcome could result in a charge to earnings. See “Part I. Item 3. Legal Proceedings” for discussions of current litigation.

2008 Outlook

We believe we have significant market opportunities in 2008 in five areas:

Fiber Deployment— we believe this market will continue to grow in 2008 and that the Regional Bell Operating Companies, or RBOCs and other communications companies, will continue to enhance their infrastructures by deploying more fiber optic cable which could increase the demand for our services.

Satellite Install to the Home— we believe the increased number of DIRECTV^® subscribers and expansion of high definition video programming provides us with the opportunity to provide maintenance services for the existing customers and opportunities to provide similar, or unrelated, installation services for new customers.

Federal Market for Telecommunications Upgrades— the Federal government is currently upgrading, or has planned to upgrade, many of its telecommunications networks and systems for military bases, ports, borders and security systems. We are making a concerted effort to market to major government contracting firms.

Local Maintenance Work for Electrical Grid Upgrades— we believe market and other conditions are making it increasingly attractive for utilities to outsource their maintenance activities and we are marketing our services for additional transmission, distribution and substation work.

Alternative Energy Projects— we believe this market will continue to grow in 2008 and we recently made an acquisition to expand our capabilities in this area. Our primary focus in this area is the construction of wind farm infrastructure.

Our 2008 results could be adversely affected by the matters discussed in the “Cautionary Statement Regarding Forward-looking Statements”, “Item 1A. Risk Factors” and “Item 3. Legal Proceedings” of this Annual Report on Form 10-K.

The following discussion and analysis of our results of operations should be read in conjunction with our consolidated financial statements and notes thereto in Item 8 of this Form 10-K.

Comparison of Years Ended December 31, 2007 and 2006

Revenue.Our revenue was $1,037.8 million for the year ended December 31, 2007, compared to $940.4 million for the same period in 2006, representing an increase of $97.4 million or 10.4%. The increase from 2006 to 2007 was due primarily to higher revenue of approximately $104.5 million from DIRECTV^®. The DIRECTV^® increase was primarily due to subscriber activations from our February 2007 acquisition and an increase in the number of work orders. Revenue from Verizon increased by $16.8 million, mainly due to higher volume of work orders. We also experienced increases in revenues from American Electric Power, the City of Ft. Lauderdale and XTO Energy in amounts of $8.4 million, $7.2 million, and $6.3 million, respectively, when compared to the prior year. These increases were partially offset by a decrease in revenue of $25.6 million from AT&T, a decrease in revenue of $11.3 million from Florida Power and Light due to termination of unprofitable contracts, and a decrease in revenue for Comcast Cable Communications, Inc. of $8.3 million.

Costs of Revenue.Our costs of revenue were $891.6 million or 85.9% of revenue for the year ended December 31, 2007, compared to $808.1 million or 85.9% of revenue for the same period in 2006. The increase of $83.5 million was generally attributable to the higher revenues achieved during the year ended December 31, 2007. Our gross margin of 14.1%, excluding depreciation, remained consistent in 2007 when compared to 2006 reflecting our continued ability to sustain margins.

Depreciation.Depreciation was $17.0 million or 1.6% of revenue for the year ended December 31, 2007, compared to $14.5 million or 1.5% of revenue for the same period in 2006, representing an increase of $2.5 million. The increase was primarily due to capital expenditures and capital lease agreements that we executed during 2006 and 2007 to finance machinery and equipment.

General and administrative expenses. General and administrative expenses were $114.7 million or 11.1% of revenue for the year ended December 31, 2007, compared to $73.4 million or 7.8% of revenue for the same period in 2006, representing an increase of $41.3 million. The increase in general and administrative expenses was mainly attributable to $38.6 million of the $39.3 million of expenses recorded during 2007 related to actual or expected settlement of legal cases, disputes and other contingencies, including litigation and other disputes related to accounts receivables. Excluding the impact of the $38.6 million of expenses recorded during 2007, general and administrative expense for the year ended December 31, 2007 would have been $76.1 million or 7.3% of revenue as compared to the $73.4 million, or 7.8% of revenue in 2006.

Interest expense, net.Interest expense, net of interest income was $9.2 million or 0.9% of revenue for the year ended December 31, 2007 compared to $10.1 million or 1.1% of revenue for the same period in 2006 representing a decrease of $0.9 million. The decrease was due to higher interest income, which increased $2.5 million, from $4.4 million for the year ended December 31, 2006 to $6.9 million for the year ended December 31, 2007, mostly due to higher outstanding cash and investment balances. Offsetting the increase in interest income was an increase of $1.7 million in interest expense, from $14.4 million for the year ended December 31, 2006 to $16.1 million for the year ended December 31, 2007, mostly due to an increase in average long term debt outstanding, as a result of the issuance of our $150 million 7.625% senior notes in 2007.

Other income net.Other income was $3.5 million or 0.3% of revenue for the year ended December 31, 2007, compared to $8.0 million or 0.8% of revenue for year ended December 31, 2006, representing a decrease of $4.5 million. The decrease is mainly due to a $5.7 million reduction in income earned during 2007 from our ownership in an equity investment. As discussed in Note 3 in our Notes to Consolidated Financial Statements, effective February 1, 2007, we acquired the remaining 51% interest and consolidated the results of this entity. As such, beginning February 1, 2007, no equity income was recorded for this entity as their results of operations are consolidated, whereas for the year ended December 31, 2006, we recorded $5.8 million in equity income related to this entity. This decrease in other income is partially offset by an increase of $1.0 million in gains on sale of property and equipment, from $2.1 million for the year ended December 31, 2006 to $3.1 million for the year ended December 31, 2007.

Benefit for income taxes.For 2007 and 2006, our effective tax rate was 0%. Our balance sheet as of December 31, 2007 and 2006 includes a net deferred tax asset of $56.9 million and $57.0 million, respectively, net of valuation allowance. The realization of this net deferred tax asset is dependent on our ability to generate future pretax income. We anticipate that we will generate sufficient pretax income in the future to realize a portion of our net deferred tax asset relating to federal income taxes. In making this assessment, we have considered our projected future pretax income to realize our remaining deferred tax assets. In the event that our future pretax income is insufficient for us to use our deferred tax assets, we believe that the deferred tax assets are still realizable based on prudent and feasible tax planning strategies available to us. However, these tax planning strategies may not be viable for the purpose of realizing all of the various income tax components of our net deferred tax asset. Accordingly, we recorded a net change to our valuation allowance of $1.3 million in 2007 to reduce certain of our net deferred federal, foreign and state tax assets at December 31, 2007, to their estimated net realizable value of $56.9 million.

Minority interest.Minority interest for GlobeTec Construction resulted in a charge of $2.5 million for the year ended December 31, 2007, compared to a charge of $2.3 million for the same period in 2006, representing an increase of $0.2 million. GlobeTec experienced an increase in business profits during 2007 compared to 2006, however, we also increased our ownership interest in GlobeTec acquiring an additional 45% equity interest during the year ended December 31, 2007. The net effect of the increase in profits and increase in ownership resulted in a slight increase in the minority interest charge for 2007. See Note 3 “Acquisitions” in Notes to Consolidated Financial Statements.

Discontinued operations.The loss from discontinued operations which mainly includes the operations of the state Department of Transportation related projects and assets, and our Canadian operations was $13.6 million for the year ended December 31, 2007 compared to $90.4 million for the year ended December 31, 2006, representing a decrease of $76.8 million. The decrease was mostly due to the sale of our state Department of Transportation related projects and assets effective February 1, 2007. On January 24, 2008, we negotiated a settlement with the buyers of our state Department of Transportation projects and assets, who had raised certain warranty, indemnification and other claims primarily related to work we had performed on the projects which the buyers purchased. Under the terms of the Settlement Agreement, MasTec paid $6.0 million in cash. As a result, we recorded a charge of $6.0 million which is reflected in our loss from discontinued operations for the year ended December 31, 2007. As such, the results of operations for our state Department of Transportation related projects and assets for the year ended December 31, 2007 was a loss of $12.3 million, which included the settlement charges, other changes in estimates and one month of operation in 2007, compared to a loss of $88.8 million for the year ended December 31, 2006 a decrease of $76.5 million compared to the prior year. The net loss attributable to our discontinued Canadian operations was $1.3 million for the year ended December 31, 2007 compared to $1.1 million for the year ended December 31, 2006, a decrease of $0.2 million.

Comparison of Years Ended December 31, 2006 and 2005

Revenue.Our revenue was $940.4 million for the year ended December 31, 2006, compared to $838.7 million for the same period in 2005, representing an increase of $101.7 million or 12.1%. This increase was due primarily to the increased revenue of approximately $83.5 million from DIRECTV^®, driven by a greater number of installations and larger market share resulting from the DSSI acquisition, higher revenue of $3.3 million from AT&T mostly attributable to work we were awarded for central office installations and an increase in general business activities from other customers during 2006 compared to 2005. These increases in revenue were partially offset by a decrease in revenue of $9.6 million from Verizon mostly attributed to the timing of generating work orders. During the year ended December 31, 2005, fiber-to-home installations for Verizon had commenced and work orders were high whereas the installations normalized during 2006. In addition, during 2005, we experienced an increase in revenue related to storm restoration in the Gulf Coast and Southern Florida, while we did not have any significant revenue from storm restoration during 2006.

Costs of Revenue.Our costs of revenue were $808.1 million or 85.9% of revenue for the year ended December 31, 2006, compared to $722.4 million or 86.1% of revenue for the same period in 2005 reflecting a slight improvement in margins. The improvement in margins was a result of decreasing subcontractor costs as a percentage of revenue with operational payroll only slightly increasing as a percentage of revenue. In 2006, we reduced the use of subcontractors and did not hire additional employees at the same rate as in 2005. The decrease in costs of revenue as a percentage of revenue was partially offset by rising fuel costs. Fuel costs, as a percentage of revenue, increased from 3.1% in the year ended December 31, 2005 to 3.6% in the year ended December 31, 2006.

Depreciation.Depreciation was $14.5 million for the year ended December 31, 2006, compared to $16.1 million for the same period in 2005, representing a decrease of $1.6 million. The decrease in depreciation expense in 2006 compared to 2005 was primarily due to our continued increase in use of operating leases for fleet requirements. We also continued to dispose of excess equipment. However, depreciation expense is expected to increase in the future as a result of several capital lease agreements we entered into during 2006 to finance various machinery and equipment totaling $8.6 million.

General and administrative expenses. General and administrative expenses were $73.4 million or 7.8% of revenue for the year ended December 31, 2006, compared to $62.0 million or 7.4% of revenue for the same period in 2005, representing an increase of $11.4 million or 18.4%. The increase in general and administrative expenses was mostly attributable to an increase in non-cash stock compensation expense and increases in legal fees. Non-cash stock compensation expense was $7.4 million or 0.8% of revenue during the year ended December 31, 2006, compared to $0.6 million during 2005 representing an increase of $6.8 million. Effective January 1, 2006, we account for stock-based award plans in accordance with SFAS 123R (revised 2004), “Shared Based Payment”, which requires us to expense over the vesting period the fair-value of stock options and other equity-based compensation issued to employees. In accordance with SFAS 123R, we expensed $6.0 million during the year ended December 31, 2006 related to unvested

stock options and restricted stock awards. In addition, we recorded approximately $1.4 million related to restricted stock options and restricted stock awards during the year ended December 31, 2006. For the year ended December 31, 2005, we expensed $0.6 million related to restricted stock awards. Had we adopted SFAS 123R in 2005, we would have been required to expense $6.9 million during the year ended December 31, 2005. See the pro forma compensation expense disclosure in Note 1 to our audited consolidated financial statements. These increases in general and administrative expenses were partially offset by a decrease in insurance expense. The reduction in insurance expense was a result of improved claims and loss history during 2006, as well as a reduction in our insurance reserve based on a change to the discount factor used for estimating actuarial insurance reserves. The discount factor was changed from 3.5% to 5.2% to reflect current market conditions and to use a discount factor more in line with the market interest rate we receive on our investments.

Interest expense, net.Interest expense, net of interest income was $10.1 million or 1.1% of revenue for the year ended December 31, 2006 compared to $19.3 million or 2.3% of revenue for the same period in 2005 representing a decrease of $9.2 million or 47.7%. The decrease was due to lower interest rates charged during 2006 under our Credit Facility and the 2006 Amendment, as well as a reduction in interest expense due to our redemption of $75.0 million principal of our 7.75% senior subordinated notes on March 2, 2006. In addition, the decrease in interest expense, net, was due to the higher interest income we earned during 2006 as a result of investing the remaining net proceeds from our January 2006 equity offering and higher interest rates earned on our invested funds.

��Other income net.Other income was $8.0 million or 0.8% of revenue for the year ended December 31, 2006, compared to $4.1 million or 0.5% of revenue for year ended December 31, 2005, representing an increase of $3.9 million. The increase mainly relates to income earned in 2006 of approximately $5.8 million associated with our equity investment in a limited liability company compared to $0.3 million recognized during 2005. On February 6, 2007, we acquired the remaining 51% equity interest of this entity. As a result, commencing in February 2007, we consolidated the results of operations of the acquired entity with our operations. This increase in other income was partially offset by a decrease in the net gains we recorded related to sales of fixed assets in the year ended December 31, 2006. Net gain on the sale of fixed assets was approximately $2.0 million during the year ended December 31, 2006 compared to approximately $2.8 million of net gains in the year ended December 31, 2005.

Benefit for income taxes.For 2006 and 2005, our effective tax rates were 0%. Our balance sheet as of December 31, 2006 and 2005 includes a net deferred tax asset of $57.0 million and $56.8 million, respectively, net of valuation allowance. The realization of this net deferred tax asset is dependent on our ability to generate future pretax income. We anticipate that we will generate sufficient pretax income in the future to realize a portion of our net deferred tax asset relating to federal income taxes. In making this assessment, we have considered our projected future pretax income to realize our remaining deferred tax assets. In the event that our future pretax income is insufficient for us to use our deferred tax assets, we believe that the deferred tax assets are still realizable based on prudent and feasible tax planning strategies available to us. However, these tax planning strategies may not be viable for the purpose of realizing all of the various income tax components of our net deferred tax asset. Accordingly, we recorded an addition to our valuation allowance of $15.3 million in 2006 to reduce certain of our net deferred federal, foreign and state tax assets at December 31, 2006, to their estimated net realizable value of $57.0 million.

Minority interest.Minority interest for GlobeTec Construction, LLC, in which we own a 51% stake, resulted in a charge of $2.3 million for the year ended December 31, 2006, compared to a charge of $1.7 million of minority interest for the same period in 2005, representing an increase of $0.6 million. GlobeTec experienced an increase in business profits during 2006 compared to 2005, resulting in an increase in minority interest charge for 2006.

Discontinued operations.The loss from discontinued operations which includes our Brazilian and network services operations, as well as our operations of the state Department of Transportation related projects and assets, was $90.4 million or 9.6% of revenue for the year ended December 31, 2006 compared to $35.9 million or 4.3% of revenue in year ended December 31, 2005. The net loss on our state Department of Transportation related projects and assets amounted to $88.8 million for the year ended December 31, 2006 compared to a net loss of $31.5 million in the year ended December 31, 2005. The net loss for these state Department of Transportation projects increased due to impairment charges, lower revenue, and operational cost overruns and inefficiencies on certain existing projects. During the second quarter of 2006, we determined there were sufficient indicators of impairment to the carrying value of the underlying net assets of the state Department of Transportation projects and assets. As a result, a $20.8 million non-cash impairment charge was recorded in the second quarter of 2006 for the estimated selling price and disposition of the state Department of Transportation projects and these assets. All impairment charges are included in discontinued operations. On November 9, 2006, we entered into an agreement to sell the state Department of Transportation related projects and assets to a third party. The contractual selling price in that agreement was less than we estimated in the impairment charge recorded in the quarter ended June 30, 2006. As a result, a non-cash impairment charge was recorded during the quarter ended September 30, 2006 of approximately $13.7 million based on the contractual selling price and our estimated closing costs. Effective February 1, 2007, we sold the state Department of Transportation related projects and net assets for $1.0 million in cash paid at closing, in addition to an earnout contingent on future operations of the projects sold, up to a maximum of $12.0 million. As a result, an additional impairment charge of $10.0 million was recorded during the quarter ended December 31, 2006.

In addition to the impairment charges related to the sale of the Department of Transportation related projects, the loss during the year ended December 31, 2006 as compared to the year ended December 31, 2005 included increased legal expenses of approximately $1.9 million and bad debt expense of approximately $4.8 million. In addition, we had increased operating expenses related to stock compensation expense of $0.2 million related to a terminated executive, duplication of back-office functions in order to ensure an easier transition and moving costs related to the consolidation of office space. The net loss for our Brazilian operations for the year ended December 31, 2006 was approximately $0.1 million and was attributable to legal fees related to the Brazilian operations bankruptcy proceedings. The net loss for our network services operations decreased to approximately $0.3 million for the year ended December 31, 2006 from a net loss of $1.7 million in the year ended December 31, 2005 as a result of the winding down of the network services operations. The loss for network services operations in the year ended December 31, 2006 is mostly attributable to personnel and legal costs in winding down the operations.

Financial Condition, Liquidity and Capital Resources

Our primary sources of liquidity are cash flows from continuing operations, availability under our credit facility, capital lease arrangements, and proceeds from sales of assets, securities, and investments. On January 31, 2007, we issued $150.0 million of 7.625% senior notes due February 2017. On March 2, 2007, we used $121.8 million of the proceeds from the senior note offering to redeem all of our remaining 7.75% senior subordinated notes plus interest. The remaining net proceeds from the senior note offering will generally be used for working capital, acquisitions of assets and businesses and other general corporate purposes. On January 24, 2006, we completed a public offering of 14,375,000 shares of our common stock at $11.50 per share. The net proceeds from the sale were approximately $156.5 million after deducting underwriting discounts and offering expenses. On March 2, 2006, we used $75.5 million of the net proceeds of the public offering to redeem a portion of our 7.75% senior subordinated notes due February 2008, including the payment of related interest.

Our primary liquidity needs are for working capital, capital expenditures, insurance collateral in the form of cash and letters of credit, earnout obligations and debt service. In addition to ordinary course working capital requirements, we estimate that we will spend between $30.0 million to $45.0 million per year on capital expenditures. We will, however, because of our improved financial condition, continue to evaluate lease versus buy decisions to meet our equipment needs and based on this evaluation, our capital expenditures may increase from this estimate in the future. We expect to continue to sell older vehicles and equipment as we upgrade with new equipment and we expect to obtain proceeds from these sales. Following the January 2007 issuance of the $150.0 million senior notes due 2017, our semi-annual interest payments have increased to approximately $5.7 million for the senior notes from approximately $4.7 million.

In February 2007, we used $15.0 million in cash in connection with the acquisition of the remaining 51% equity interest in an investment in which we previously owned a 49% interest. We have also agreed to pay the seller an earnout based on future performance through the eighth anniversary of the closing date.

In October 2007, we acquired all the outstanding shares of capital stock of Three Phase Line Construction, Inc., an entity specializing in the construction and maintenance of transmission and distribution utility systems, substation and storm restoration in several northern states, for a purchase price of $8.0 million in cash. We have also agreed to pay the seller an earnout based on future performance of the acquired entity through the fifth anniversary of the closing date.

In December 2007, we acquired certain assets and assumed certain liabilities of Power Partners, L.L.C., an electrical utility contractor, specializing in wind farm construction. The purchase price was for $5.5 million in cash and the assumption of up to $1.1 million in liabilities. We have also agreed to pay the sellers an earnout based on the future performance of the entity through the fifth anniversary of the closing date.

For the year ended December 31, 2007, we paid approximately $3.0 million for earnout obligations in connection with acquisitions we have made.

We hold a variety of highly rated interest bearing auction rate securities that most often represent interests in pools of either collateralized debt obligations, student loans, or taxable municipal bonds. These auction rate securities provide liquidity via an auction process that resets the applicable interest rate at predetermined calendar intervals, usually every 7, 28, or 35 days. This mechanism allows existing investors either to rollover their holdings, whereby they would continue to own their respective interest in the auction rate security, or to gain immediate liquidity by selling such interests at par. Certain of these auctions have not had sufficient bidders to allow investors to complete a sale, indicating that immediate liquidity at par is unavailable. As of December 31, 2007, we have identified approximately $16.2 million of investments subject to this auction process for which there have been insufficient bidders on the scheduled auction dates and we held another approximately $33.0 million of these securities. Subsequent to year end, of the approximately $33.0 million of these securities, $8.5 million were sold at par, approximately $7.9 million had insufficient bidders and failed the reset process, and we believe the remaining approximately $16.6 million may be temporarily at risk of having this occur. While the investments are of a high credit quality and the rating has not been lowered, at this time we are uncertain when the liquidity issues associated with these investments will improve and when we will be able to exit these investments at their par value. We currently anticipate holding these securities until we can realize their par value and feel that our existing cash resources will be sufficient to meet our anticipated needs for working capital and capital expenditures to execute our current business plan. We are continuing to monitor this situation. See Note 5 “Securities available for Sale” in Notes to Consolidated Financial Statements.

We need working capital to support seasonal variations in our business, primarily due to the impact of weather conditions on external construction and maintenance work, including storm restoration work, and the corresponding spending by our customers on their annual capital expenditure budgets. Our business is typically slower in the first and fourth quarters of each calendar year and stronger in the second and third quarters. Accordingly, we generally experience seasonal working capital needs from approximately April through September to support growth in unbilled revenue and accounts receivable, and to a lesser extent, inventory. Our billing terms are generally net 30 to 60 days, although some contracts allow our customers to retain a portion (from 2% to 15%) of the contract amount until the contract is completed to their satisfaction. We maintain inventory to meet the material requirements of some of our contracts. Some of our customers pay us in advance for a portion of the materials we purchase for their projects, or allow us to pre-bill them for materials purchases up to a specified amount.

Our vendors generally offer us terms ranging from 30 to 90 days. Our agreements with subcontractors usually contain a “pay-when-paid” provision, whereby our payments to subcontractors are made only after we are paid by our customers.

We anticipate that funds generated from continuing operations, our cash and cash equivalents, borrowings under our credit facility, and proceeds from sales of assets and investments will be sufficient to meet our working capital requirements, anticipated capital expenditures, insurance collateral requirements, and earnout obligations, letters of credit and debt service obligations for at least the next twelve months.

As of December 31, 2007, we had $159.5 million in working capital compared to $164.0 million as of December 31, 2006. Cash and cash equivalents increased to $74.3 million at December 31, 2007, including $18 million in restricted cash, from $35.3 million at December 31, 2006.

Net cash provided by operating activities was $68.7 million for the year ended December 31, 2007, primarily related to a decrease in net loss, reductions in discontinued operations assets and increases in non-cash items, primarily the provision for doubtful accounts and accruals for legal settlements. Non-cash items during 2007 primarily included depreciation and amortization, the gain on disposal of assets and investments, stock and restricted stock compensation and accrued losses on construction projects, provision for doubtful accounts, minority interest and the net effect related to legacy litigation. Changes in working capital and changes in other assets provided $34.2 million in operating cash flow in 2007, including a reduction in cash collateral requirement to our insurance carrier of $3.3 million and timing of cash payments to vendors and cash collections from customers. Net cash provided by operating activities was $46.4 million for the year ended December 31, 2006, primarily as a result of our operating loss adjusted for changes in working capital and changes in other assets, including a reduction in cash collateral requirements provided to our insurance carrier and non-cash items. Non-cash items during 2006 primarily included charges for impairment of assets of $44.5 million, depreciation and amortization, the gain on disposal of assets and investments, accrued losses on construction projects and provision for doubtful accounts minority interest.

Net cash used in investing activities was $62.5 million and $94.7 million for the years ended December 31, 2007 and 2006, respectively. Net cash used in investing activities for the year ended December 31, 2007 primarily related to capital expenditures in the amount of $32.1 million and payments made in connection with acquisitions in amount of $35.4 million, partially offset by $3.2 million in net proceeds from sales of assets and investments. Net cash used in investing activities for the year ended December 31, 2006 primarily related to capital expenditures in the amount of $22.3 million, payments made in connection with the DSSI acquisition of $19.3 million and payments related to our equity investment in amount of $4.7 million partially offset by $6.2 million in net proceeds from the sale of assets.

Net cash provided by financing activities was $32.8 million for the year ended December 31, 2007 compared to net cash provided by financing activities of $81.8 million for the year ended December 31, 2006. Net cash provided by financing activities for the year ended December 31, 2007 was primarily related to net proceeds from the issuance of $150.0 million of 7.625% senior notes due February 2017, and issuance of common stock pursuant to stock options exercises in amount of $13.9 million. These proceeds were partially offset by the redemption of $121.0 million 7.75% senior subordinated notes in February 2007 and repayments of borrowings of $3.9 million. Net cash provided by financing activities for the year ended December 31, 2006 was primarily related to the net proceeds from the issuance of common stock of $156.5 million and proceeds from the issuance of common stock pursuant to stock option exercises in the amount of $4.6 million offset by the redemption of $75.5 million principal on our senior subordinated notes and payments of borrowings of $3.8 million.

We have a secured revolving credit facility under which we may borrow up to $150 million, subject to certain adjustments and restrictions (the “Credit Facility”). Pursuant to an amendment of the Credit Facility that became effective June 30, 2007, the expiration date of the Credit Facility was extended from May 10, 2010 to May 10, 2012. The amendment added an accordion feature which allows us to request an increase in the maximum amount borrowed under the Credit Facility from $150 million to $200 million, if certain criteria under the credit facility is met. This amendment also reduced the interest rate margin applied to borrowings and increased the maximum available amount we can borrow at any given time, among other things. Deferred financing costs related to the Credit Facility are included in prepaid expenses and other current assets, and in other assets in our consolidated balance sheets.

The amount that we can borrow at any given time is based upon a formula that takes into account, among other things, eligible billed and unbilled accounts receivable, equipment, real estate and eligible cash collateral, which can result in borrowing availability of less than the full amount of the Credit Facility. At December 31, 2007 and December 31, 2006, net availability under the Credit Facility totaled $44.0 million and $35.1 million, respectively, which includes outstanding standby letters of credit aggregating $86.4 million and $83.3 million in each period, respectively. At December 31, 2007, $64.8 million of the outstanding letters of credit were issued to support MasTec’s casualty and medical insurance requirements. These letters of credit mature at various dates and most have automatic renewal provisions subject to prior notice of cancellation. The Credit Facility is collateralized by a first priority security interest in substantially all of our assets and a pledge of the stock of certain of our operating subsidiaries. Substantially all of our wholly-owned subsidiaries collateralize the Credit Facility. At December 31, 2007 and December 31, 2006, we had no outstanding cash draws under the Credit Facility. Interest under the Credit Facility accrues at variable rates based, at our option, on the agent bank’s base rate plus a margin of between 0.0% and 0.50%, or at the LIBOR rate (as defined in the Credit Facility) plus a margin of between 1.00% and 2.00%, depending on certain financial thresholds. Through December 31, 2007, the Credit Facility provided that the margin over LIBOR will be no higher than 1.125%, and currently the margin we pay over LIBOR is 1.125%. The Credit Facility includes an unused facility fee of 0.25%.

The Credit Facility contains customary events of default (including cross-default) provisions and covenants related to our operations that prohibit, among other things, making investments and acquisitions in excess of specified amounts, incurring additional indebtedness in excess of specified amounts, paying cash dividends, making other distributions, creating liens against our assets, prepaying other indebtedness excluding our 7.625% senior notes, and engaging in certain mergers or combinations without the prior written consent of the lenders. In addition, any deterioration in the quality of billed and unbilled receivables, reduction in the value of our equipment or an increase in our lease expense related to real estate, would reduce availability under the Credit Facility.

If the net availability under the Credit Facility does not exceed $15.0 million, MasTec is required to be in compliance with a minimum fixed charge coverage ratio of 1.1 to 1.0 measured on a monthly basis, and certain other events are triggered. The $15.0 million availability trigger is subject to adjustment if the maximum amount we may borrow under the Credit Facility is adjusted. The fixed charge coverage ratio is generally defined to mean the ratio of our net income before interest expense, income tax expense, depreciation expense, and amortization expense minus net capital expenditures and cash taxes to the sum of all interest expense plus current maturities of debt for the period. The financial covenant was not applicable as of December 31, 2007 because at that time the net availability under the Credit Facility did not decline below the required threshold specified above.

Based upon our current liquidity and projections for 2008, we believe we will be in compliance with the credit facility’s terms and conditions and the minimum availability requirements in 2008. We are dependent upon borrowings and letters of credit under this credit facility to fund operations. Should we be unable to comply with the terms and conditions of the credit facility, we would be required to obtain further modifications to the credit facility or another source of financing to continue to operate. We may not be able to achieve our 2008 projections and thus may not be in compliance with the credit facility’s minimum net availability requirements and minimum fixed charge ratio in the future.

Our variable rate credit facility exposes us to interest rate risk. We had no cash borrowings outstanding under the credit facility at December 31, 2007.

As of December 31, 2007, we had outstanding $150.0 million, 7.625% senior notes due in 2017, with interest due semi-annually which we issued on January 31, 2007. We used approximately $121.8 million of the net proceeds from this offering to redeem all of our 7.75% senior subordinated notes plus interest. The 7.625% senior notes contain default (including cross default) provisions and covenants restricting, among others, many of the same transactions as under our credit facility. The indenture that governs our senior notes allows us to incur the additional indebtedness or issue preferred stock under our credit facility (up to $200.0 million), and for renewals of existing debt permitted under the indenture plus an additional $50.0 million. The indenture prohibits incurring further indebtedness unless our fixed charge coverage ratio is greater than 2:1 for the four most recently ended fiscal quarters determined on a pro forma basis as if that additional debt has been incurred at the beginning of the period. In addition, the indenture prohibits incurring additional capital lease obligations in excess of 5% of our consolidated net assets at any time the senior notes remain outstanding.

Our credit standing and senior notes are rated by various agencies.

The following table sets forth our contractual commitments as of December 31, 2007 during the periods indicated below (in thousands):


			Payments Due By Period
									More than

(1)		Amounts do not include interest payments.

(2)		On February 6, 2007, we acquired the remaining 51% equity interest in an investment where we previously owned 49% for $15.0 million in cash, and issued 300,000 shares of our common stock. In addition to the 51% acquisition completed in 2007, we have made other acquisitions and have agreed to pay the sellers earnouts based on the performance of the businesses acquired. Due to the contingent nature of these earnout payments, we have only included earnout obligations which are presently quantifiable.

Off-balance sheet arrangement.We provide letters of credit to secure our obligations primarily related to our insurance arrangements and surety bonds. We also provide letters of credit related to legal matters. Total letters of credit reduce our available borrowings under our credit facility and amounted to $86.4 million at December 31, 2007 of which $64.8 million were related to our insurance programs.

Some of our contracts require us to provide performance and payment bonds, which we obtain from a surety company. If we were unable to meet our contractual obligations to a customer and the surety paid our customer the amount due under the bond, the surety would seek reimbursement of such payment from us. At December 31, 2007, the cost to complete on our $294.8 million performance and payment bonds was $46.2 million.

Seasonality

Our operations are historically slower in the first and fourth quarters of the year. This seasonality is primarily the result of the effect of weather on our external activities and customer budgetary constraints and preferences. Some of our customers tend to complete budgeted capital expenditures before the end of the year and defer additional expenditures until the following budget year.

Impact of Inflation

The primary inflationary factor affecting our operations is increased labor costs. We did not experience significant increases in labor costs in 2007, 2006 or 2005. To a lesser extent, we are also affected by changes in fuel costs which increased significantly in 2007 and 2006.

Recently Issued Accounting Pronouncements

See Note 1 — Nature of the Business and Summary of Significant Accounting Policies in “Item 8. Financial Statements and Supplementary Data.”

Item 7A.Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk related to changes in interest rates and fluctuations in foreign currency exchange rates.

Interest Rate Risk

Less than 8% of our outstanding debt at December 31, 2007 was subject to variable interest rates. The remainder of our debt has fixed interest rates. Our fixed interest rate debt includes $150 million (face value) in senior notes. The carrying value and market value of our debt at December 31, 2007 was $163.0 million and $154.7 million, respectively. Based upon debt balances outstanding at December 31, 2007, a 100 basis point (i.e. 1%) addition to our weighted average effective interest rate for variable rate debt would increase our interest expense by less than $0.1 million on an annual basis.

Our variable rate credit facility exposes us to interest rate risk. We had no cash borrowings outstanding under our revolving credit facility at December 31, 2007.

Foreign Currency Risk

We had an investment in a subsidiary in Canada and sold our services into this foreign market. On March 30, 2007, our Board of Directors voted to sell substantially all of our Canadian operations. On April 10, 2007, we sold substantially all of our Canadian operations. Accordingly, the operations in Canada have been accounted for as discontinued operations for all periods presented. See Note 11 in “Notes to our Consolidated Financial Statements.”

Our foreign net asset/exposures (defined as assets denominated in foreign currency less liabilities denominated in foreign currency) for Canada at December 31, 2007 of U.S. dollar equivalents was $0.3 million compared to $1.7 million as of December 31, 2006.

See Note 1 of Notes to Consolidated Financial Statements in Item 8 of this Report for further disclosures about market risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and
Shareholders of MasTec, Inc.

We have audited the accompanying consolidated balance sheets of MasTec, Inc. and subsidiaries as of December 31, 2007 and 2006 and the related consolidated statements of operations, changes in shareholders’ equity, and cash flows for the three years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of MasTec, Inc. as of December 31, 2007 and 2006, and the consolidated results of their operations and their cash flows for the three years then ended in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for uncertain tax positions as of January 1, 2007 and the way it accounted for share-based compensation as of January 1, 2006. Also, as discussed in Note 1 to the consolidated financial statements, the Company has reclassified its Consolidated Balance Sheet as of December 31, 2006 and Consolidated Statement of Cash Flows for the year ended December 31, 2006 to reflect the reclassification of certain financial instruments from “Cash and cash equivalents” to “Securities available for sale”.

We also have audited, in accordance with the Standards of the Public Company Accounting Oversight Board (United States), the effectiveness of MasTec, Inc.’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated February 27, 2008, expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — Nature of the Business and Summary of Significant Accounting Policies

MasTec, Inc. (collectively, with its subsidiaries, “MasTec”, “we,” “us,” “our” or the “Company”) is a leading specialty contractor operating mainly throughout the United States and across a range of industries. Our core activities are the building, installation, maintenance and upgrade of communications and utility infrastructure. Our primary customers are in the following industries: communications (including satellite television and cable television), utilities and government. MasTec provides similar infrastructure services across the industries it serves. Customers rely on us to build and maintain infrastructure and networks that are critical to their transport and delivery of voice, video and data communications, electricity and other energy resources.

The following is a summary of the significant accounting policies followed in the preparation of the accompanying consolidated financial statements:

Management estimates.The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. The more significant estimates relate to our revenue recognition, allowance for doubtful accounts, intangible assets, accrued insurance, income taxes, litigation and contingencies. Estimates are based on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for judgments about results and the carrying values of assets and liabilities. Actual results and values may differ from these estimates.

Principles of consolidation.The accompanying consolidated financial statements include MasTec, Inc. and its subsidiaries. We consolidate GlobeTec Construction, LLC as we have a controlling interest in the company. Other parties’ interest in this entity is reported as minority interest in the consolidated financial statements. All intercompany accounts and transactions have been eliminated in consolidation.

Reclassifications.Certain reclassifications were made to the prior year financial statements in order to conform to the current period presentation. Auction rate securities previously classified as “Cash and cash equivalents” have been reclassified to “Securities Available for Sale” on the Consolidated Balance Sheet and the Consolidated Statement of Cash Flows as of December 31, 2006 to conform to the current presentation.

As discussed in Note 11, on March 30, 2007, we reached the decision to sell substantially all of our Canadian operations, accordingly, these operations have been classified as discontinued operations and are not included in the results of continuing operations for any periods presented. In addition, current and long-term assets, as well as current and non-current liabilities, have been reclassified on the consolidated balance sheet as of December 31, 2006 to conform to the current presentation.

Comprehensive Income (loss).Comprehensive income (loss) is a measure of net gain (loss) and all other changes in equity that result from transactions other than with shareholders. Comprehensive income (loss) consists of foreign currency translation adjustments and unrealized losses on securities available for sale in the years ended December 31, 2007, 2006 and 2005.

Revenue recognition.Revenue and related costs for master and other service agreements billed on a time and materials basis are recognized as the services are rendered. There are also some service agreements that are billed on a fixed fee basis. Under our fixed fee master service and similar type service agreements, MasTec furnishes various specified units of service for a separate fixed price per unit of service. For service agreements on a fixed fee basis, profitability will be reduced if the actual costs to complete each unit exceed original estimates.

In addition to master and other service agreements we enter into contracts that require the installation or construction of specified units within an infrastructure system. Under these contracts, revenue is recognized at the contractually agreed price per unit as the units are completed and delivered. Profitability will be reduced if the actual costs to complete each unit exceed original estimates. We also are required to immediately recognize the full amount of any estimated loss on these projects if estimated costs to complete the remaining units for the project exceed the revenue to be earned on such units.

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

We also enter into fixed price, long-term installation/construction contracts that primarily require the construction and installationof an entire infrastructure system. We recognize revenue and related costs as work progresses on fixed price, long-term contracts using the percentage-of-completion method, which relies on contract revenue and estimates of total expected costs. We estimate total project costs and profit to be earned on each long-term, fixed-price contract. We follow this method since reasonably dependable estimates of the revenue and costs applicable to various stages of a contract can be made. Under the percentage-of-completion method, we record revenue and recognize profit or loss as work on the contract progresses. The cumulative amount of revenue recorded on a contract at a specified point in time is that percentage of total estimated revenue that incurred costs to date bear to estimated total contract costs. We recognize the full amount of any estimated loss on a contract at the time the estimates indicate such a loss.

Our customers generally supply materials such as cable, conduit and telephone equipment. Customer furnished materials are not included in revenue and cost of sales as these materials are purchased by the customer. The customer determines the specification of the materials that are to be utilized to perform installation/construction services. We are only responsible for the performance of the installation/construction services and not the materials for any contract that includes customer furnished materials and we have no risk associated with customer furnished materials. Our customers retain the financial and performance risk of all customer furnished materials.

Billings in excess of costs and estimated earnings on uncompleted contracts are classified as current liabilities. Any costs and estimated earnings in excess of billings are classified as current assets. Work in process on contracts is based on work performed but not billed to customers as per individual contract terms.

Basic and diluted net income (loss) per share. The computation of basic net income (loss) per common share is based on the weighted average number of common shares outstanding during each period. The computation of diluted net income (loss) per common share is based on the weighted average number of common shares outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options and unvested restricted stock (“common stock equivalents”). For the year ended December 31, 2007 and 2006 diluted net income (loss) per common share includes the effect of common stock equivalents in the amount of 1,479,000 and 1,545,000 shares, respectively. For the year ended December 31, 2005, common stock equivalents of approximately 843,000 shares were not included in the diluted net loss per common share because their effect would be anti-dilutive.

Allowance for doubtful accounts.We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. Management analyzes past due balances based on invoice date, historical bad debt experience, customer concentrations, customer credit-worthiness, customer financial condition and credit reports, the availability of mechanic’s and other liens, the existence of payment bonds and other sources of payment, and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Management reviews the adequacy of the reserves on a quarterly basis. Amounts are written off against the allowance when deemed uncollectible.

Cash and cash equivalents.All short-term investments with maturities of three months or less when purchased are considered to be cash equivalents stated at cost which approximates market value. Restricted cash related to collateral of the credit facility is also included in cash and cash equivalents.

Securities available for sale.We account for securities available-for-sale in accordance with the provisions of “Accounting For Certain Debt and Equity Securities”(“SFAS 115”). Securities available-for-sale are recorded at fair value, and temporary unrealized holding gains and losses are recorded, net of tax, as a separate component of accumulated other comprehensive income (loss). Unrealized losses are charged against net earnings when a decline in fair value is determined to be other-than-temporary. In accordance with FSP FAS 115-1 and 124-1,“The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments,”we review several factors to determine whether a loss is other-than-temporary. These factors include but are not limited to: i) the length of time a security is in an unrealized loss position, ii) the extent to which fair value is less than cost, iii) the financial condition and near term prospects of the issuer and, iv) our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Inventories.Inventories consist of materials and supplies for construction and install to the home projects, and are typically purchased on a project-by-project basis. Inventories are valued at the lower of cost (using the specific identification method) or market. Construction projects are completed pursuant to customer specifications. The loss of the customer or the cancellation of the project could result in an impairment of the value of materials purchased for that customer or project. Technological or market changes can also render certain materials obsolete. Allowances for inventory obsolescence are determined based upon the specific facts and circumstances for each project and market conditions. There was no obsolescence provision included in 2007. During 2006 and 2005, we recorded a provision for inventory obsolescence of approximately $0.6 million and $1.0 million, respectively, in “Costs of revenue” and “Loss on discontinued operations” in the Consolidated Statements of Operations.

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

Property and equipment.Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful lives of the improvements. Expenditures for repairs and maintenance are charged to expense as incurred. Expenditures for betterments and major improvements are capitalized and depreciated over the remaining useful life of the asset. The carrying amounts of assets sold or retired and related accumulated depreciation are eliminated in the year of disposal and the resulting gains and losses are included in other income or expense.

Deferred costs.Deferred financing costs related to our credit facility and the senior notes whose short and long-term portions are included in other current and non-current assets in the consolidated balance sheets are amortized over the related terms of the debt using the effective interest method. Net deferred financing costs were $6.4 million and $3.9 million at December 31, 2007 and 2006, respectively.

Software capitalization.The Company capitalizes certain costs incurred in connection with developing or obtaining internal use software in accordance with American Institute of Certified Public Accountants Statement of Position 98-1, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use.” These capitalized software costs are included in “Property and equipment, net” in the consolidated balance sheets and are being amortized over a period not to exceed seven years.

Valuation of Equity Investments.At December 31, 2006, we had an investment which we accounted for by the equity method because we owned 49% of the entity and had the ability to exercise significant influence over the operational policies of the limited liability company. As discussed in Note 3 in “Notes to Consolidated Financial Statements”, on February 6, 2007, we acquired the remaining 51% equity interest of this entity.

Valuation of Long-Lived Assets.Management reviews long-lived assets, consisting primarily of property and equipment and intangible assets with finite lives, for impairment in accordance with Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”). In analyzing potential impairment, we use projections of future discounted cash flows from the assets. These projections are based on our view of growth rates for the related business, anticipated future economic conditions and the appropriate discount rates relative to risk and estimates of residual values. We believe that our estimates are consistent with assumptions that marketplace participants would use in their estimates of fair value.

Valuation of Goodwill and Intangible Assets.In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”), we conduct, on at least an annual basis, a review of our reporting entities to determine whether the carrying values of goodwill exceed the fair value using a discounted cash flow methodology for each entity. Should this be the case, the value of goodwill may be impaired and written down. Goodwill acquired in a purchase business combination and determined to have an infinite useful life is not amortized, but instead tested for impairment at least annually in accordance with the provisions of SFAS No. 142. In addition, acquired intangible assets are required to be recognized and amortized over their useful lives if the benefit of the asset is based on contractual or legal rights.

In the year ended December 31, 2005, we charged $11.5 million, against goodwill related to the decision to sell substantially all of our state Department of Transportation related projects and assets.

During the year ended December 31, 2007, we recorded approximately $52.2 million of additional goodwill and other intangible assets in connection with acquisitions and payments of earnouts made throughout the year. See Note 3 “Acquisitions” in Notes to Consolidated Financial Statements.

Accrued insurance.MasTec maintains insurance policies subject to per claim deductibles of $1 million for its workers’ compensation policy, $2 million for its general liability policy and $3 million for its automobile liability policy. We have excess umbrella coverage for losses in excess of the primary coverages of up to $100 million per claim and in the aggregate. We also maintain an insurance policy with respect to employee group health claims subject to per claim deductibles of $300,000 after satisfying an annual deductible of $100,000. All insurance liabilities are actuarially determined on a quarterly basis for unpaid claims and associated expenses, including the ultimate liability for claims incurred and an estimate of claims incurred but not reported. The

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

accruals are based upon known facts, historical trends and a reasonable estimate of future expenses. However, a change in experience or actuarial assumptions could nonetheless materially affect results of operations in a particular period. Known amounts for claims that are in the process of being settled, but have been paid in periods subsequent to those being reported, are also recorded in such reporting period.

Income taxes.We record income taxes using the liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequence of temporary differences between the financial statement and income tax bases of our assets and liabilities. We estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our tax exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. The recording of a net deferred tax asset assumes the realization of such asset in the future. Otherwise a valuation allowance must be recorded to reduce this asset to its net realizable value. Management considers future pretax income and ongoing prudent and feasible tax planning strategies in assessing the need for such a valuation allowance. In the event that we determine that we may not be able to realize all or part of the net deferred tax asset in the future, a valuation allowance for the deferred tax asset is charged against income in the period such determination is made.

Stock based compensation.In the first quarter of 2006, MasTec adopted Statement of Financial Accounting Standards No. 123 (revised 2004),“Share-Based Payment”(“SFAS 123R”). This Statement requires companies to expense the estimated fair value of stock options and similar equity instruments issued to employees over the vesting period in their statement of operations. SFAS 123R eliminates the alternative to use the intrinsic method of accounting provided for in Accounting Principles Board Opinion No. 25,“Accounting for Stock Issued to Employees”(“APB 25”), which generally resulted in no compensation expense recorded in the financial statements related to the grant of stock options to employees if certain conditions were met.

We adopted SFAS 123R using the modified prospective method effective January 1, 2006, which requires us to record compensation expense over the vesting period for all awards granted after the date of adoption, and for the unvested portion of previously granted awards that remain outstanding at the date of adoption. Accordingly, amounts for periods prior to January 1, 2006 presented herein have not been restated to reflect the adoption of SFAS 123R. The pro forma effect of the 2005 prior period is as follows and has been disclosed to be consistent with prior accounting rules (in thousands, except per share data):

On August 23, 2005, the compensation committee of our Board of Directors approved the acceleration and vesting of all unvested stock options having an exercise price in excess of current market value on or before December 31, 2005 for option grants under the Company’s 2003 Employee Stock Incentive Plan (current employees, including executive officers) and the Company’s 2003 Stock Incentive Plan for Non-Employees, as amended. Stock option awards granted in 2003 and 2004 with respect to 769,000 shares of the Company’s common stock were accelerated resulting in approximately $4.1 million of pro forma compensation expense in the pro forma calculation for the year ended December 31, 2005. These options were not fully achieving their original objectives of incentive compensation and employee retention. These accelerations had a positive effect on employee morale, retention and perception of option value. The acceleration also eliminated future compensation expense the Company recognized in its consolidated statement of operations with respect to these options as required by SFAS 123R.

We also grant restricted stock, which is valued based on the market price of the common stock on the date of grant. Compensation expense arising from restricted stock grants is recognized using the ratable method over the vesting period. Unearned compensation for performance-based options and restricted stock is shown as a reduction of shareholders’ equity in the consolidated balance sheets.

Fair value of financial instruments.We estimate the fair value of financial instruments through the use of public market prices, quotes from financial institutions and other available information. Judgment is required in interpreting data to develop estimates of market value and, accordingly, amounts are not necessarily indicative of the amounts that we could realize in a current market exchange. Short-term financial instruments, including cash and cash equivalents, accounts and notes receivable, accounts payable and other liabilities, consist primarily of instruments without extended maturities, the fair value of which, based on management’s estimates, approximated their carrying values. At December 31, 2007 and 2006, the fair value of senior notes was $154.7 million and $121.0 million, respectively, based on quoted market values. MasTec uses letters of credit to back certain insurance policies. The letters of credit reflect fair value as a condition of their underlying purpose and are subject to fees competitively determined in the marketplace.

New accounting pronouncements.In December 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 141(R),“Business Combinations” (SFAS 141(R)) and Statement of Financial Accounting Standards No. 160 “Accounting and Reporting of Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB No. 51” (SFAS 160). SFAS 141(R) and SFAS 160 significantly change the accounting for and reporting of business combination transactions and noncontrolling (minority) interests. SFAS 141(R) and SFAS 160 are effective for the fiscal years beginning after December 15, 2008. SFAS 141(R) and SFAS 160 are effective prospectively; however, the reporting provisions of SFAS 160 are effective retroactively. SFAS 141(R) is required to be adopted concurrently with SFAS 160 and is effective for business combination transactions for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We are currently evaluating the impact of the adoption of SFAS 141(R) and SFAS 160 on our consolidated financial statements.

On February 15, 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities — Including an Amendment of FASB Statement No. 115” (“SFAS 159”). This standard permits an entity to measure financial instruments and certain other items at estimated fair value. Most of the provisions of SFAS No. 159 are elective; however, the amendment to SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities,”applies to all entities that own trading and available-for-sale securities. The fair value option created by SFAS 159 permits an entity to measure eligible items at fair value as of specified election dates. The fair value option (a) may generally be applied instrument by instrument, (b) is irrevocable unless a new election date occurs, and (c) must be applied to the entire instrument and not to only a

portion of the instrument. SFAS 159 is effective as of the beginning of the first fiscal year that begins after November 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity (i) makes that choice in the first 120 days of that year, (ii) has not yet issued financial statements for any interim period of such year, and (iii) elects to apply the provisions of Statement of Financial Accounting Standards No. 157 (“SFAS 157”),“Fair Value Measurements.”We are currently evaluating the impact of SFAS 159, if any, on our consolidated financial statements.

In November 2006, the Emerging Issues Task Force reached a consensus on Issue No. 06-04, “Accounting for Deferred Compensation and Postretirement Benefit Aspects of Endorsement Split of Endorsement Split-Dollar Life Insurance Arrangements��, (“EITF 06-04”). EITF 06-04 reached a consensus that for a split-dollar life insurance arrangement that provides a benefit to an employee that extends to postretirement periods, an employer should recognize a liability for future benefits in accordance with Statement of Financial Accounting Standards No. 106, “Employers’ Accounting for Postretirement Benefits Other Than Pensions”, (“SFAS 106”) or APB Opinion 12 (depending upon whether a substantive plan is deemed to exist) based on the substantive agreement with the employee. This consensus was effective for fiscal years beginning after December 15, 2006 and did not have a material effect on our consolidated financial statements.

In November 2006, the Emerging Issues Task Force reached a consensus on Issue No. 06-05, “Accounting for Purchase of Life Insurance-Determining the Amount That Could Be Realized in Accordance with FASB Technical Bulletin No. 85-04”, (“EITF 06-05”). EITF 06-05 reached a consensus that a policyholder should consider any additional amounts included in the contractual terms of the policy in determining the amount that could be realized under the insurance contract. The Task Force agreed that contractual limitations should be considered when determining the realizable amounts. Those amounts that are recoverable by the policyholder at the discretion of the insurance company should be excluded from the amount that could be realized. The Task Force also agreed that fixed amounts that are recoverable by the policyholder in future periods in excess of one year from the surrender of the policy should be recognized at their present value. The Task Force also reached a consensus that a policy holder should determine the amount that could be realizable under the life insurance contract assuming the surrender of an individual-life by individual policy (or certificate by certificate in a group policy). The Task Force noted that any amount that is ultimately realized by the policyholder upon the assumed surrender of the final policy (or final certificate in a group policy) shall be included in the amount that could be realized under the insurance contract. This consensus was effective for fiscal years beginning after December 15, 2006 and did not have a material effect on our consolidated financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans – an amendment of FASB Statements No. 87, 88 and 132(R)” (“SFAS 158”). This statement requires an employer to recognize the funded status of a benefit plan as an asset or liability in its financial statements. The funded status is measured as the difference between plan assets at fair value and the plan’s specific benefit obligation, which would be the projected benefit obligation. Under SFAS 158, the gains or losses and prior service cost or credits that arise in a period but are not immediately recognized as components of net periodic benefit expense will now be recognized, net of tax, as a component of other comprehensive income. SFAS 158 is effective for fiscal years ending after December 15, 2008. We do not expect this pronouncement to have a material effect on our consolidated financial statements.

In September 2006, the Securities and Exchange Commission (“SEC”) staff issued Staff Accounting Bulletin No. 108 (“SAB 108”), “Considering the effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.” Traditionally, there have been two widely recognized methods for quantifying the effects of financial statement misstatements: the “roll-over” method and the “iron-curtain” method. The roll-over method focuses primarily on the impact of a misstatement on the income statement, including the reversing effect of prior year misstatements. The iron-curtain method focuses primarily on the effect of correcting the period-end balance sheet with less emphasis on the reversing effects of prior year errors on the income statement. In SAB 108, the SEC staff established an approach that is commonly referred to as a “dual approach” because it now requires quantification of errors under both the iron-curtain and the roll-over methods. SAB 108 is effective for the fiscal year ending December 31, 2006. The adoption of SAB 108 did not have any effect on MasTec’s financial position, net earnings or prior year financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (“SFAS 157”), “Fair Value Measurements.” This statement establishes a single authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. SFAS 157 defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” SFAS 157 is effective for the fiscal year after November 15, 2007. We are currently evaluating this standard to determine its impact, if any, on our consolidated financial statements.

Note 2 — Sale of the Company’s Common Stock

On January 24, 2006, MasTec completed a public offering of 14,375,000 shares of our common stock at $11.50 per share. The net proceeds from the sale were approximately $156.4 million after deducting underwriting discounts and offering expenses. We used $18.5 million of the net proceeds for the cash portion of the purchase price for the DSSI acquisition, as described in Note 3 below. On March 2, 2006, we used $75.5 million of the net proceeds of the public offering to redeem a portion of our 7.75% senior subordinated notes due February 2008.

Note 3 — Acquisitions

Acquisition of Digital Satellite Services, Inc.

Effective January 31, 2006, we acquired substantially all of the assets and assumed certain operating liabilities and contracts of Digital Satellite Services, Inc., which we refer to as the DSSI acquisition. The purchase price was composed of $18.5 million in cash, $6.9 million of MasTec common stock (637,214 shares based on the closing price of MasTec’s common stock of $11.77 per share on January 27, 2006 discounted by 8.75% due to the shares being restricted for 120 days), $0.9 million of estimated transaction costs and an earnout based on future performance. We registered the resale of these shares on April 28, 2006.

DSSI was involved in the installation of residential and commercial satellite and security services in several markets including Atlanta, Georgia, the Greenville-Spartanburg area of South Carolina and Asheville, North Carolina, and portions of Tennessee, Kentucky and Virginia. These markets are contiguous to areas in which we are active with similar installation services. Following the DSSI acquisition, we provide installation services from the mid-Atlantic states to South Florida.

The purchase price allocation for the DSSI acquisition is based on fair-value of each of the following components on January 31, 2006 (in thousands):


Net assets	$	2,026
Non-compete agreement		658
Goodwill		23,559

Purchase price	$	26,243

The operations of DSSI are immaterial to our consolidated financial statements.

Acquisition of Remaining Interest in Our 49% Equity Investment.

In September 2004, MasTec purchased a 49% interest in a limited liability company from a third party. The purchase price for this investment was an initial amount of $3.7 million which was paid in four quarterly installments of $925,000 through December 31, 2005. Beginning in the first quarter of 2006, eight additional contingent quarterly payments were expected to be made to the third party from which the interest was purchased. The contingent payments were to be up to a maximum of $1.3 million per quarter based on the level of unit sales and profitability of the limited liability company in specified preceding quarters. The first five quarterly payments, each of $925,000, were made on January 10, 2006, April 10, 2006, July 11, 2006, October 10, 2006 and January 10, 2007. The January 10, 2007 amount was included in accrued expenses and other assets at December 31, 2006. In March 2006, The entity requested an additional capital contribution in the amount of $2.0 million of which $980,000, or 49%, was paid by MasTec.

Effective February 1, 2007, we acquired the remaining 51% equity interest in this investment. As a result of our acquisition of the remaining 51% equity interest, we have consolidated the operations of the acquired entity with our results commencing in February 2007. In February 2007, we paid the seller $8.65 million in cash, in addition to approximately $6.35 million which we also paid at that time to discharge our remaining obligations to the seller under the purchase agreement for the original 49% equity interest, and issued to the seller 300,000 shares of our common stock. We have also agreed to pay the seller an earnout through the eighth anniversary of the closing date based on the future performance of the acquired business. In connection with the purchase, we entered into a service agreement with the sellers for them to manage the business. Under certain circumstances, including a change of control of MasTec or the acquired entity or in certain cases a termination of the service agreement, the remaining earnout payments will be accelerated and become payable. Under certain circumstances, we may be required to invest up to an additional $3.0 million in the acquired entity. In connection with the acquisition, we registered for resale 300,000 shares of the total shares issued to the seller. On May 15, 2007, this registration statement was declared effective by the SEC.

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

The purchase price allocation for the 51% acquisition of this entity is based on the fair-value of each of the components as of February 1, 2007 (in thousands):


Net assets	$	3,281
Tradename		476
Non-compete agreement		311
Contract Intangible		5,941
Customer related intangible		774
Goodwill		928

Purchase price	$	11,711

The purchase price for the original 49% equity interest exceeded the carrying value of the net assets as of original acquisition date and accordingly the excess was considered goodwill.

The non-compete agreements are in force with the former shareholders of the acquired entity and are being amortized over their contractual life. Customer related intangibles are being amortized using an accelerated method over five years.

Prior to the acquisition of the remaining 51% equity interest, we accounted for this investment using the equity method as we had the ability to exercise significant influence over the financial and operational policies of this limited liability company. We recognized approximately $0.1 million, $5.8 million and $0.3 million in equity income during the years ended December 31, 2007, 2006 and 2005, respectively. As of December 31, 2006 the carrying amount of this investment was approximately $15.7 million and was included in other assets in the consolidated balance sheet.

Acquisition of Additional Ownership interest in GlobeTec

During 2007, we acquired an additional 45% ownership interest in GlobeTec Construction, LLC (“GlobeTec”) for $6.5 million in cash. In addition to the cash payments, we have agreed to pay certain sellers an earnout based on future performance through the fourth anniversary of the closing date. As a result of these investments, our ownership interest in GlobeTec increased from 51% to 96% during the year ended December 31, 2007. The aggregate purchase price of $6.5 million has been allocated, on a preliminary basis, to the estimated fair value of acquired tangible assets of $2.9 million and identifiable intangible assets of $0.7 million, resulting in goodwill totaling $2.9 million.

Acquisition of Three Phase Line Construction, Inc.

In October 2007, we acquired all the outstanding shares of capital stock of Three Phase Line Construction, Inc. for a purchase price of $8.0 million in cash, subject to adjustments, and an earnout based on future performance of the acquired entity through the fifth anniversary of the closing date based on fiscal year. We may, at our option, issue shares of our common stock to the sellers of Three Phase Line Construction, Inc. in connection with the earnout for this acquisition. Three Phase Line Construction is involved in the construction and maintenance of transmission and distribution utility systems, substation and storm restoration in several northern states. The purchase price, including acquisition cost, of approximately $0.1 million has been allocated, on a preliminary basis, to the estimated fair value of acquired tangible assets of $3.3 million, assumed liabilities of $1.9 million, and identifiable intangible assets of $0.7 million, resulting in goodwill totaling $6.0 million.

Acquisition of Power Partners, LLC.

In December 2007, we acquired certain assets, of Power Partners, LLC. for $5.5 million in cash, and assumed certain liabilities of $1.1 million and agreed to pay the seller an earnout based on future performance through the fifth anniversary of the closing date. Power Partners, LLC, is an electrical utility contractor specializing in wind farm construction. The purchase price of approximately $6.6 million has been allocated, on a preliminary basis, to the estimated fair value of acquired tangible assets of $0.2 million, and identifiable intangible assets of $0.5 million resulting in goodwill totaling $5.9 million.

None of the acquisitions made during the year ended December 31, 2007 were material, either individually or in the aggregate, to our revenue, results of operations and financial position.

Note 4 — Goodwill and Other Intangible Assets

SFAS No. 142 requires companies to stop amortizing goodwill and certain intangible assets with an infinite useful life. Instead, SFAS No. 142 requires that goodwill and certain intangible assets deemed to have an infinite useful life be reviewed for impairment upon adoption of SFAS No. 142 and annually thereafter.

Under SFAS No. 142, goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value as determined using a discounted cash flow methodology applied to the particular entity.

During the year ended December 31, 2007, we recorded approximately $52.2 million of goodwill and other identifiable intangible assets in connection with acquisitions and payment of earnouts made throughout the year.

During the fourth quarters of 2007, 2006 and 2005, management performed its annual review of goodwill and certain identifiable intangible assets with an infinite useful life for impairment. No additional impairment charges for 2007, 2006 and 2005 were required as a result of this review. In the year ended December 31, 2005, we charged $11.5 million against goodwill related to the decision to sell substantially all of our state Department of Transportation related projects and assets.

At December 31, 2007, identifiable intangible assets amount to approximately $10.7 million, including $3.6 million of identifiable intangible assets with finite lives. At December 31, 2006 identifiable intangible assets amount to approximately $1.3 million. We continue to amortize identifiable intangible assets that have a finite useful life. Total amortization expense related to these identifiable intangible assets was $1.0 million, $0.3 million and $0.2 million in 2007, 2006 and 2005, respectively.

Identifiable intangible assets that have a finite useful life will be amortized as summarized in the following table:

Note 5 —Securities available for sale

Securities available for sale consist of auction rate securities that most often represent interest in pools of either collateralized debt obligations, student loans, taxable municipal bonds and similar securities. Unrealized gains and losses related to auction rate securities are included in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity. While the underlying securities of auction rate securities may have contractual maturities of more than ten years, the interest rates on such securities reset at intervals of 7, 28 or 35 days. Auction rate securities are priced and trade as short-term investments and are considered available-for-sale investments because of such interest rate reset feature and expected liquidity.

As of December 31, 2007, we have identified approximately $16.2 million of investments subject to this auction process for which there have been insufficient bidders at the scheduled rollover dates and held another approximately $33.0 million of these securities. As a result, we recorded an unrealized loss of $4.8 million in 2007. Subsequent to year end, of the approximately $33.0 million of these securities, $8.5 million were sold at par, approximately $7.9 million had insufficient bidders and failed the reset process, and we believe the remaining approximately $16.6 million may be at risk of having this occur. While the investments are of a high credit quality and the rating of these securities has not been lowered, at this time we are uncertain when the liquidity issues associated with these investments will improve, when we will be able to exit these investments at their par value or whether we will incur any additional losses as a result of these investments.

The cost basis, gross unrealized gains and losses and fair value for these securities are as follows:


			December 31, 2007									December 31, 2006
			Gross		Gross							Gross		Gross
	Cost		Unrealized		Unrealized			Fair		Cost		Unrealized		Unrealized		Fair

Management reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be realizable. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the assets carrying amount to determine if an impairment of such asset is necessary. The effect of any impairment would be to expense the difference between the fair value of such asset and its carrying value.

Revolving Credit Facility

The amount that we can borrow at any given time is based upon a formula that takes into account, among other things, eligible billed and unbilled accounts receivable, equipment, real estate and eligible cash collateral, which can result in borrowing availability of less than the full amount of the Credit Facility. At December 31, 2007 and December 31, 2006, net availability under the Credit Facility totaled $44.0 million and $35.1 million, respectively, which includes outstanding standby letters of credit aggregating $86.4 million and $83.3 million in each period, respectively. At December 31, 2007, $64.8 million of the outstanding letters of credit were issued to support MasTec’s casualty and medical insurance requirements. These letters of credit mature at various dates and most have automatic renewal provisions subject to prior notice of cancellation. The Credit Facility is collateralized by a first priority security interest in substantially all of our assets and a pledge of the stock of certain of our operating subsidiaries. Substantially all of our wholly-owned subsidiaries collateralize the Credit Facility. At December 31, 2007 and December 31, 2006, we had no outstanding cash draws under the Credit Facility. Interest under the Credit Facility accrues at variable rates based, at our option, on the agent bank’s base rate plus a margin of between 0.0% and 0.50%, or at the LIBOR rate (as defined in the Credit Facility) plus a margin of between 1.00% and 2.00%, depending on certain financial thresholds. Currently the margin we pay over LIBOR is 1.125%. The Credit Facility includes an unused facility fee of 0.25%.

If the net availability under the Credit Facility does not exceed $15.0 million, MasTec is required to be in compliance with a minimum fixed charge coverage ratio of 1.1 to 1.0 measured on a monthly basis. The $15.0 million availability trigger is subject to adjustment if the maximum amount we may borrow under the Credit Facility is adjusted. The fixed charge coverage ratio is generally defined to mean the ratio of our net income before interest expense, income tax expense, depreciation expense, and amortization expense minus net capital expenditures and cash taxes to the sum of all interest expense plus current maturities of debt for the period. The financial covenant was not applicable as of December 31, 2007 because at that time the net availability under the Credit Facility did not decline below the required threshold specified above.

We are dependent upon borrowings and letters of credit under this Credit Facility to fund operations. Should we be unable to comply with the terms and conditions of the Credit Facility, we would be required to obtain further modifications of the Credit Facility or obtain another source of financing to continue to operate. We may not be able to achieve our 2007 projections and thus may not be in compliance with the Credit Facility’s minimum net availability requirements and minimum fixed charge ratio in the future.

The variable rate Credit Facility exposes us to interest rate risk.

Senior Notes

As of December 31, 2007, $150.0 million of our 7.625% senior notes due in February 2017, with interest due semi-annually were outstanding. The notes contain default (including cross-default) provisions and covenants restricting many of the same transactions as under our credit facility. The indenture which governs our senior notes allows us to incur the following additional indebtedness among others: the credit facility (up to $200 million), renewals to existing debt permitted under the indenture plus an additional $50 million of indebtedness, further indebtedness if our fixed charge coverage ratio is at least 2:1 for the four most recently ended fiscal quarters determined on a pro forma basis as if that additional debt has been incurred at the beginning of the period. In addition, the indenture prohibits incurring additional capital lease obligations in excess of 5% of our consolidated net assets at any time the senior notes remain outstanding. The definition of our fixed charge coverage ratio under the indenture is essentially equivalent to that under our credit facility.

MasTec had no holdings of derivative financial or commodity instruments at December 31, 2007.

Capital Leases

During 2007, we entered into agreements which provided financing for various machinery and equipment totaling $6.2 million. These capital leases are non-cash transactions and, accordingly, have been excluded from the consolidated statements of cash flows. These leases range between 60 and 72 months and have effective interest rates ranging from 3.31% to 5.12%. In accordance with Statement of Financial Accounting Standard No. 13, “Accounting for Leases” (“SFAS 13”), as amended, these leases were capitalized. SFAS 13 requires the capitalization of leases meeting certain criteria, with the related asset being recorded in property and equipment and an offsetting amount recorded as a liability. As of December 31, 2007, we had $12.3 million in total indebtedness relating to the capital leases entered into during 2007, of which $10.0 million was considered long-term.

Note 10 — Lease Commitments

We have operating lease agreements for premises and equipment that expire on various dates. The operating lease agreements are subject to escalation. Rent expense from continuing operations for the years ended December 31, 2007, 2006 and 2005 was approximately $48.1 million, $50.2 million and $47.5 million, respectively.

We also have capital lease agreements for equipment that expire on various dates.

Note 11 — Discontinued Operations

During the fourth quarter 2004, we ceased performing new services in the network services operations and sold these operations in 2005. On May 24, 2005, the Company sold certain assets of its network services operations to a third party for $0.2 million consisting of $0.1 million in cash and a promissory note in the principal amount of $0.1 million due in May 2006. We recorded a loss on sale of approximately $0.6 million, net of tax, in the year ended December 31, 2005. The loss on sale resulted from additional selling costs and remaining obligations that were not assumed by the buyer. These operations have been classified as a discontinued operation in all periods presented. The net loss for the years ended December 31, 2007, 2006 and 2005, for the network services operations was $0.0 million, $0.3 million and $1.7 million, respectively.

On December 31, 2005, the executive committee of our Board of Directors voted to sell substantially all of our state Department of Transportation related projects and assets. The decision to sell was made after evaluation of short and long-term prospects. The projects and assets that went for sale have been accounted for as discontinued operations for all periods presented. During the year ended December 31, 2005, we wrote-off approximately $11.5 million in goodwill in connection with our decision to sell substantially all of these related projects and assets. We determined that this goodwill amount would not be realized after evaluating the cash flows from the operations of these projects and assets in light of our decisions on future operations and our decision to sell. The remaining

net asset value was also reviewed by management and impairment charges were recorded to reserve for inventory items that were considered obsolete, accounts receivable that was considered uncollectible, write-off of fixed assets that were no longer in use or not saleable, estimated cost to complete for all projects in process and accrued estimated losses on the projects. We also assumed closing costs and other liabilities expected from the sale. As a result, we recorded impairment charges totaling $2.9 million and $44.5 million during the years ended December 31, 2007 and 2006, respectively. Effective on February 1, 2007, we sold the state Department of Transportation related projects and net assets. We agreed to keep certain assets and liabilities related to the state Department of Transportation related projects. The sales price of $1.0 million in cash was paid at closing. In addition, the buyer is required to pay us an earnout of up to $12.0 million contingent on the future operations of the projects sold. However, as the earnout is contingent upon the future performance of the state Department of Transportation related projects, we may not receive any of these earnout payments.

On January 24, 2008, we entered into a settlement with the buyer of our state Department of Transportation projects and assets to settle previously disclosed warranty, indemnification and other claims primarily relating to work we had performed on the projects which were sold. Under the terms of the Settlement Agreement, MasTec paid $6.0 million in cash and obtained a covenant not to sue and general release from nearly all obligations owed by us to the buyer under the purchase agreement including warranty and other indemnification obligations. As a result of the settlement, we have recorded a charge of $6.0 million which is reflected in our loss from discontinued operations for the year ended December 31, 2007.

On March 30, 2007, our Board of Directors voted to sell substantially all of our Canadian operations. The decision to sell was made after our evaluation of short and long term prospects for these operations. Due to this decision, operations in Canada have been accounted for as discontinued operations for all periods presented. In addition, we reviewed the carrying value of the net assets related to our Canadian operations. During the year ended December 31, 2007, we wrote-off $0.4 million in goodwill in connection with our decision to sell substantially all of our Canadian net assets. Based on management’s estimate and expected selling price, we recorded a non-cash impairment charge of approximately $0.6 million. On April 10, 2007, we sold substantially all of our Canadian for approximately $1.0 million. The purchase price is subject to adjustments based on the value of the net assets sold as of March 31, 2007.

Note 12 — Retirement and Stock Option Plans

MasTec has a 401(k) plan covering all eligible employees. Subject to certain dollar limits, eligible employees may contribute up to 15% of their pre-tax annual compensation to the plan. We did not match employee contributions in 2004 and 2005. Commencing in the first quarter of 2006, we began to match contributions under the 401(k) plan. MasTec matches $0.50 on the dollar for the first 2% of the employee’s contribution which is payable in common shares of MasTec.

We have granted options to purchase our common stock to our employees and members of our Board of Directors and our affiliates under various stock option plans at no less than the fair market value of the underlying stock on the date of grant. These options are granted for a term not exceeding ten years and are forfeited in the event the employee or director terminates his or her employment or relationship with us or one of our affiliates. All option plans contain anti-dilutive provisions that require the adjustment of the number of shares of our common stock represented by each option for any stock splits or dividends.

We have five stock option plans that have stock options outstanding as of December 31, 2007: the 1994 Stock Incentive Plan (the “1994 Plan”), the 1994 Stock Option Plan for Non-Employee Directors (the “Directors’ Plan”), the 1999 Non-Qualified Option Plan (the “Non-Qualified Plan”), the 2003 Employee Stock Incentive Plan as amended (the “2003 Plan”) and the Amended and Restated 2003 Stock Incentive Plan for Non-Employees as amended (the “2003 Non-Employee Plan”) and individual option agreements. Typically, options under these plans are granted at fair market value at the date of grant, vest between three to five years after grant and terminate no later than 10 years from the date of grant. The 1994 Plan and the Directors Plan expired in 2004 and no future stock options can be granted under these plans. During 2006, MasTec entered into the Deferred Fee Plan for its directors.

The 2003 Non-Employee Plan was adopted in April 2003 and authorized granting of restricted stock to non-employees. We have reserved 2,500,000 shares of common stock for grant under the 2003 Non-Employee Plan which covers stock options or restricted stock awards. We grant restricted stock which is valued based on the market price of the common stock on the date of grant. Compensation expense arising from restricted stock grants is recognized using the ratable method over the period of the restrictions. Unearned compensation for the restricted stock is shown as a reduction of shareholders’ equity in the consolidated balance sheets. We approved the issuance of restricted stock to the Board of Directors and certain employees in 2006. In the year ended December 31, 2007,

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

we issued 284,388 shares of restricted stock to key employees and certain board members, which were valued at approximately $3.4 million and are being expensed over a vesting period ranging from 12 to 36 months. In the year ended December 31, 2006, we issued 104,751 shares of restricted stock to key employees and board members. Total unearned compensation related to restricted stock grants as of December 31, 2007 and 2006 is $2.5 million and $0.7 million, respectively. Restricted stock expense for the years ended December 31, 2007, 2006 and 2005 is $1.5 million, $1.4 million and $.05 million, respectively.

Under these plans there were a total of 5,622,935, 5,526,667 and 6,354,015 options available for grant at December 31, 2007, 2006 and 2005, respectively. The 1997 Non-Qualified Employee Stock Purchase Plan also allows eligible employees to purchase the MasTec’s common stock through payroll deductions or in a lump sum at a 15% discount from fair market value. The amount of compensation expense related to these transactions is immaterial.

Note 13 — Income Taxes

We adopted Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement 109,” (“FIN 48”) in the first quarter of 2007. FIN 48 is an interpretation of FASB Statement No. 109, “Accounting for Income Taxes,” and seeks to reduce the diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. FIN 48 prescribes a recognition threshold and measurement attribute for

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

financial statement recognition and measurement of a tax position that an entity takes or expects to take in a tax return. Under FIN 48, an entity may only recognize or continue to recognize tax positions that meet a “more likely than not” threshold. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based on management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recognized the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in our financial statements.

On January 1, 2007, we recorded the cumulative effect of applying FIN 48 of $1.9 million as an adjustment to the balance of deferred tax assets, and an offset to the valuation allowance on that deferred tax asset. As of the adoption date, we had no accrued interest expense or penalties related to the unrecognized tax benefits. Interest and penalties, if incurred, would be recognized as a component of income tax expense. There are no open Federal tax years under audit.

The expense (benefit) for income taxes from continuing operations consists of the following (in thousands):

At December 31, 2007, we had approximately $176 million of net operating loss carryforwards for U.S. federal income tax purposes that expire beginning in 2022. We have net operating loss carryforwards for U.S. state and local purposes of approximately $18.1 million that expire from 2007 to 2026. We have an unrealized excess tax benefit of approximately $1.7 million, that when realized, will increase capital surplus.

In assessing the ability to realize the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which these temporary differences become deductible. Management considers the projected future taxable income and prudent and feasible tax planning strategies in making this assessment. As of December 31, 2007 and 2006, valuation allowances of $47.9 million and $49.2 million have been recorded, respectively.

Accordingly, results of operations for all periods presented reflect our Canadian business as discontinued and our results from continuing operations for all periods presented relate only to our United States operations.

Note 15 — Commitments and Contingencies

Change in Strategy Regarding Litigation and Other Disputes.In the third quarter of 2007, our senior management performed a reassessment of our major legal cases, claims and other disputes, including disputes involving amounts due us, and decided to accelerate the closure of a number of these matters, particularly older legal cases, claims and disputes from the years 2001 through2005, which generally do not involve current customers. In part, this decision was driven by a desire to reduce the high levels of legal expense and related costs that we have incurred in recent years, and to reduce the amount of management’s time devoted to litigation matters and other claims and disputes. While we will attempt to accelerate the closure of these matters, it will only do so if we believe such resolution is in the best interests of MasTec and its shareholders.

Legacy Litigation.MasTec is subject to significant outstanding litigation, primarily dating from the period 2001 through 2005.

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

former install to the home employees who were employed by MasTec from October 2001 through September 2007 in California, Florida, Georgia, Maryland, New Jersey, New Mexico, North Carolina, South Carolina, Texas and Virginia. The gross amount of the settlement is up to $12.6 million, and is subject to court approval. This amount represents the maximum payout, assuming 100% opt-in by all potential members of the purported class.

During 2003 and 2004, we provided services to MSE Power Systems on five separate projects in Pennsylvania, New York and Georgia, with invoices in excess of $8 million in dispute. In 2004, we filed suit against MSE seeking payment. To date, we have recovered $1.3 million from MSE in settlement on three of these projects and are seeking additional amounts owed us. An arbitration was held in August 2007, and in January 2008, we were awarded a $2.65 million judgment in connection therewith.

In November 2004, MasTec entered into, and bonded, a conditional $12.6 million settlement of litigation brought for subcontract work done in 2001 by Hugh O’Kane Electric for MasTec on a telecommunication project for Telergy in New York. Telergy is in bankruptcy and did not pay MasTec for this work. The settlement was conditioned upon the resolution of all of the Court proceedings including appeals. MasTec filed an appeal seeking to enforce contractual terms which relieved MasTec of its obligation to pay Hugh O’Kane when MasTec was not paid by Telergy. New York’s appellate level court upheld the enforceability of the terms of MasTec’s contract, but remanded the case to the trial court to determine whether there were factual issues that prevented MasTec from using the contractual provision as a defense. The trial court found that factual issues prevented MasTec from using the contractual provision as a defense and MasTec appealed. The appellate court upheld the trial courts ruling and MasTec has requested a rehearing, which was denied.

MasTec, Inc.
Notes To Consolidated Financial Statements — continued

In April 2006, we settled, without payment to the plaintiffs by us, several complaints for purported securities class actions that were filed against us and certain officers in the second quarter of 2004. As part of the settlement, our excess insurance carrier has retained the rights to seek reimbursement of up to $2.0 million from us based on its claim that notice was not properly given under the policy. We are also seeking reimbursement of expenses incurred by us which we believe are reimbursable by our excess insurance carrier. We believe the claims of the excess insurance carrier are without merit and plan to continue vigorously pursuing this action. Although a district court ruled in March 2007 that there is no coverage provided under the excess policy, we have appealed. We are also pursuing claims against the insurance broker for any losses arising from the same issue involving notice.

Financial Statement Impact.Primarily as a result of the change in strategy noted above, we entered into settlement negotiations on several of these legal cases, claims and other disputes, including disputes involving amounts due us, reached settlement on the FLSA matter discussed above and on other disputes, and authorized settlement on a number of other matters, including certain accounts receivable for which we had been pursuing collection via negotiation or via the legal process. As a result of these negotiations and actual or anticipated settlements (including FLSA and Coos County), and other developments, we recorded charges totaling $39.1 million for the actual or anticipated settlement of litigation, claims and other disputes in the nine months ended September 30, 2007 and $0.2 million in the three months ended December 31, 2007. This charge is for the actual or anticipated settlement of legacy legal claims and other disputes, including adjustments to reserves and other valuation accounts for litigated or disputed collections, and relates mostly to the years 2001-2005.

Accrued aggregate liabilities related to the matters discussed above amounted to approximately $25.6 million at December 31, 2007, which is included in other current liabilities. Our allowance for doubtful accounts and other asset valuation accounts related to the matters discussed above amounted to $9.7 million and $4.4 million, respectively, in the year ended December 31, 2007. These charges relate mostly to the years 2001-2005.

The labor union representing the workers of Sistemas e Instalaciones de Telecomunicación S.A. (“Sintel”), a former MasTec subsidiary, initiated an investigative action with a Spanish federal court that commenced in July 2001 alleging that six former members of the Board of Directors of Sintel, including Jorge Mas, our chairman, and his brother Juan Carlos Mas, approved a series of allegedly unlawful transactions that led to the bankruptcy of Sintel. We were also named as a potentially liable party. The Court conducted extensive discovery, including the declarations of certain present and former executives of MasTec, Inc. In December 2007, the Court decided to close the investigation and issued an order allowing the trial phase against the former officers of MasTec, Inc. to proceed. The order does not name MasTec, Inc. as a potentially liable party. The union has alleged Sintel and its creditors were damaged in the approximate amount of 269 million euros ($396 million at December 31, 2007). The order is subject to appeal by several of the parties. To date, no actions have been taken by the Court against us or any of the named individuals. Our directors’ and officers’ insurance carrier has reimbursed us all of our legal fees to date and agreed to fund legal expenses for the remainder of the litigation under a reservation of rights. The amount of loss, if any, relating to this matter cannot presently be determined.

Although we believe that we have gone through review of these legacy and other matters and have developed our best estimate for settling the legacy legal cases, claims and other disputes, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future as facts and circumstances change. We have incurred substantial costs in connection with these claims and will continue to do so until there is a resolution of these matters. We can not assure you that a favorable outcome will be reached in any of these cases. If we are not able to settle these cases at the amounts estimated, or if we are subject to an unfavorable trial outcome or other final resolution on these matters, there exists the possibility of a material adverse impact on the Company’s financial position and on the results of operations for the period in which the effect becomes reasonably estimable.

Other Litigation, Claims, and Disputes.In addition to the matters discussed above, we are also subject to a variety of legal cases, claims and other disputes that arise from time to time in the ordinary course of our business.

Other Commitments and Contingencies. We are required to provide payment and performance bonds for some of our contractual commitments related to projects in process. At December 31, 2007, the cost to complete projects for which the $294.8 million in performance and payment bonds are outstanding was $46.2 million.

We are subject to certain risk factors, including, but not limited to risks related to economic downturns in the telecommunications and broadband industries, collectability of receivables, competition within our industry, the nature of our contracts (which do not obligate our customers to undertake any infrastructure projects and may be canceled on short notice), acquisition integration and financing, seasonality, availability of qualified employees, recoverability of goodwill, and potential exposures to environmental liabilities.

We have more than 280 customers which include some of the largest and most prominent companies in the communications, utilities and government industries. Our customers include incumbent local exchange carriers, broadband and satellite operators, public and private energy providers, long distance carriers, financial institutions and wireless service providers.

We grant credit, generally without collateral, to our customers. Consequently, we are subject to potential credit risk related to changes in business and economic factors. However, we generally have certain lien rights on that work and concentrations of credit risk are limited due to the diversity of the customer base. We believe our billing and collection policies are adequate to minimize potential credit risk. During the year ended December 31, 2007, 59.7% of our total revenue was attributed to three customers. Revenue from these three customers accounted for 44.1%, 9.1% and 6.8% of total revenue for the year ended December 31, 2007. During the year ended December 31, 2006, 56.0% of our total revenue was attributed to three customers. Revenue from these three customers accounted for 37.5%, 10.2% and 8.3% of the total revenue for the year ended December 31, 2006. During the year ended December 31, 2005, 53.9% of our total revenue was attributed to three customers. Revenue from these three customers accounted for 32.1%,11.4% and 10.4% of total revenue for the year ended December 31, 2005.

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. Management analyzes historical bad debt experience, customer concentrations, customer credit-worthiness, the availability of mechanics and other liens, the existence of payment bonds and other sources of payment, and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. If judgments regarding the collectability of accounts receivables were incorrect, adjustments to the allowance may be required, which would reduce profitability. As of December 31, 2007, we had remaining receivables from customers undergoing bankruptcy reorganization totaling $1.6 million net of $0.3 million in specific reserves. As of December 31, 2006, we had remaining receivables from customers undergoing bankruptcy reorganization totaling $10.4 million net of $4.1 million in specific reserves. Based on the analytical process described above, management believes that we will recover the net amounts recorded. We maintain an allowance for doubtful accounts of $15.3 million and $11.5 million as of December 31, 2007 and December 31, 2006, respectively, for both specific customers and as a reserve against other past due balances. Should additional customers file for bankruptcy or experience difficulties, or should anticipated recoveries in existing bankruptcies and other workout situations fail to materialize, we could experience reduced cash flows and losses in excess of the current allowance.

In the third quarter of 2007, we recorded approximately $38.4 million of selling and administrative expenses related to the actual or expected settlement of legal cases, disputes, and other contingencies, including litigation or other disputes involving accounts receivable.

In the fourth quarter of 2006, we recorded a non-cash impairment charge of approximately $10.0 million in connection with our sale in February 2007 of substantially all of our state Department of Transportation related projects and underlying assets.

Note 18 — Related Party Transactions

MasTec purchases, rents and leases equipment used in its business from a number of different vendors, on a non-exclusive basis, including Neff Corp. (“Neff”), in which Jorge Mas, Chairman of our Board of Directors, and Jose Mas, our President and Chief Executive Officer, were directors and owners of a controlling interest through June 4, 2005. Juan Carlos Mas, the brother of Jorge and Jose Mas, was the Chairman, Chief Executive Officer, a director and a shareholder of Neff until May 31, 2007 when he sold his Neff shares and resigned as its chief executive officer. Juan Carlos Mas remains as chairman of the Neff Board of Directors. During the years ended December 31, 2007 and 2006, we paid Neff approximately $2.4 million and $1.4 million, respectively, for equipment purchases, rentals and leases. MasTec believes the amount paid to Neff is equivalent to the payments that would have been made between unrelated parties for similar transactions acting at arm’s length.

During 2007, we paid $76,000 to Irma Mas, the mother of Jorge Mas, our Chairman and Jose Mas, our President and Chief Executive Officer, for the lease of certain property located in Florida.

During the years ended December 31, 2007 and 2006, we had an arrangement with a customer whereby we leased employees to that customer and charged approximately $0.4 million and $0.3 million, respectively, to the customer. As of December 31, 2007 and 2006, $0.4 million and $0.3 million, respectively, receivable is included within other current assets. Jorge Mas, Chairman of our Board of Directors, and Jose Mas, our President and Chief Executive Officer, are minority owners of this customer.

We charter aircrafts from a third party who leases two of its aircraft from entities in which Jorge Mas, Chairman of our Board of Directors, and Jose Mas, our President and Chief Executive Officer, have an ownership interest. We paid this unrelated chartering company approximately $0.8 million and $0.7 million during the years ended December 31, 2007 and 2006, respectively.

Effective as of August 27, 2002, MasTec and Jorge Mas entered into a split dollar agreement, as subsequently amended, wherein MasTec agreed to pay the premiums due on two life insurance policies with an aggregate face amount of $50.0 million. Mr. Mas and his spouse are the insured under the policies. Under the terms of this agreement, MasTec is the sole owner and beneficiary of the policies and is entitled to recover the greater of (i) all premiums it pays on the policies plus interest equal to four percent, compounded annually, or (ii) the aggregate cash value of the life insurance policy immediately before the death of the insureds. The remainder of the policies’ proceeds will be paid in accordance with Mr. Mas’ designations.

On November 1, 2002, MasTec and Jorge Mas entered into a deferred bonus agreement in which we agreed to pay Mr. Mas a bonus in the event that the split dollar agreements Mr. Mas had entered into with MasTec were terminated due to a change of control of MasTec. The amount of the bonus is equal to the total premiums made by MasTec under the terms of the split dollar agreements, plus interest of four percent, compounded annually. The bonus is to be paid within 60 days after termination of the split dollar agreement. The deferred bonus agreement was subsequently amended to comply with Section 409A of the Internal Revenue Code.

The deferred bonus agreement was subsequently amended to comply with Section 409A of the Internal Revenue Code.

Effective as of August 3, 2004, MasTec and Jose Mas entered into a split dollar agreement wherein we agreed to pay premiums on a life insurance policy with an aggregate face amount of $10.0 million.

Item 9A.Controls and Procedure

Evaluation of Disclosure Controls and Procedures.As of the end of the period covered by this Annual Report on Form 10-K, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange Act”). We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within specified time periods. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

In designing and evaluating our disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and are subject to certain limitations, including the exercise of judgment by individuals, the difficulty in identifying unlikely future events, and the difficulty in eliminating misconduct completely.

In connection with this annual report on Form 10-K, our Chief Executive Officer and Chief Financial Officer evaluated, with the participation of our management, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that our disclosure controls and procedures were effective as of December 31, 2007.

Management’s Report on Internal Control Over Financial Reporting.Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework inInternal Control — Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission. Our internal control over financial reporting is designed to provide reasonable assurance to management and to our Board of Directors regarding the reliability of financial reporting and the preparation and fair presentation of financial statements for external purposes in accordance with generally accepted accounting principles. MasTec’s internal control over financial reporting includes those policies and procedures that:

(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and directors of MasTec; and

(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

In connection with this annual report on Form 10-K, our Chief Executive Officer and Chief Financial Officer evaluated, with the participation of our management, the effectiveness of our internal control over financial reporting as of the end of the period covered by this report. Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that our internal control over financial reporting was effective as of December 31, 2007.

BDO SEIDMAN LLP, the independent registered public accounting firm who audits our financial statements, has audited our internal control over financial reporting as of December 31, 2007 and has expressed an unqualified opinion thereon.

Changes in Internal Controls over Financial Reporting.In preparing our financial statements for the year ended December 31, 2007, we determined that we had been improperly classifying certain auction rate securities as cash and cash equivalents as of December 31, 2006, March 31, 2007, June 30, 2007 and September 30, 2007. The proper classification is to report them separately as securities available for sale. See Notes 1 and 5 to the consolidated financial statements. In the Fourth Quarter of 2007, we determined that our prior classification of auction rate securities as cash and cash equivalents was a material disclosure control weakness and took steps to remediate this disclosure control weakness. The Company’s remediation consisted of three items. First, we revised our investment policy to preclude future investments in auction rate securities. Second, we established a more thorough and independent analysis of cash, cash equivalents and investment securities by our accounting, treasury and internal audit functions. And, finally, we added a specific quarterly disclosure control to include an examination of cash, cash equivalents and short term investment instruments by senior management prior to the finalization of the financial statements.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders
Shareholders MasTec, Inc.

We have audited MasTec, Inc.’s internal control over financial reporting as of December 31, 2007, based on criteria established inInternal Control — Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). MasTec, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Management’s Report on Internal Control Over Financial Reporting”. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, MasTec, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of MasTec, Inc. as of December 31, 2007 and 2006, as reclassified, the related consolidated statements of operations, changes in shareholders’ equity, and cash flows for the three years then ended and our report dated February 27, 2008 expressed an unqualified opinion thereon.

Summaries of Plans Not Approved by Our Shareholders

1997 Non-Qualified Employee Stock Purchase Plan.The MasTec, Inc. 1997 Non-Qualified Employee Stock Purchase Plan is administered by the Compensation Committee, and permits employees of MasTec who meet certain criteria set by the Committee to purchase our common stock at a 15% discount to the market price at the time of purchase. Such purchases are made through regular payroll deductions or lump sum investments. Employees are limited to a maximum investment of $25,000 in the plan each year. The total amount of common stock reserved under the plan is approximately 600,000 shares, substantially all of which has been purchased.

Non-Employee Directors’ Stock Plan.The MasTec, Inc. Non-Employee Directors’ Stock Plan adopted in 1999 permits non-employee directors to elect to receive all or a specified percentage of any director fees paid for each year of service on the board in shares of our common stock. The number of shares issued to each non-employee director is determined by dividing the director’s fees owed to such director by the fair-market value of a share of common stock on the date of the issue. The shares issued are delivered to the non-employee director and the non-employee director has all the rights and privileges of a stockholder as to the shares. The shares are immediately vested upon grant and are not forfeitable to us. The maximum number of shares of common stock that may be issued under the plan is 150,000. As of December 31, 2007, there were no shares available for issuance under this plan.

1999 Non-Qualified Employee Stock Option Plan.The 1999 Non-Qualified Employee Stock Option Plan is administered by the Compensation Committee of the Board and permits the Committee to grant non-qualified options to purchase up to 2,000,000 shares of common stock to any MasTec employee. The Compensation Committee determines the recipient of options, the number of shares covered by each option, and the terms and conditions of options within the parameters of the plan (including the exercise price, vesting schedule, and the expiration date) and may adopt rules and regulations necessary to carry out the plan. Options may be granted pursuant to the plan until January 31, 2009. The Compensation Committee has the authority to change or discontinue the plan or the options issued pursuant thereto at any time without the holders consent so long as the holders’ rights would not be impaired. The plan permits the Compensation Committee to determine and accept different forms of payment pursuant to the exercise of options.

The plan provides for the termination of all outstanding options whether or not vested in the event of a termination of employment, and permits the Committee to take certain actions in the event of a change of control to ensure fair and equitable treatment of the employees who hold options granted under the plan, including accelerating the vesting of any outstanding option, offering to purchase any outstanding option and making other changes to the terms of the outstanding options. As of December 31, 2007, 1,150,750 shares remained available for issuance under this plan.

Deferred Fee Plan.The Deferred Fee Plan became effective on January 1, 2006. Under the terms of the Deferred Fee Plan, directors may elect to defer the receipt of cash and stock fees for their services as directors. Each director may elect the type of fees to be deferred, the percentage of such fees to be deferred, and the form in which the deferred fees and any earnings thereon are to be paid. Deferred cash fees may be directed to a deferred cash account or a deferred stock account (or both). Deferred stock fees may only be directed to a deferred stock account. Elections to defer fees remain in force, unless amended or revoked within the required time periods.

The deferred cash account will be credited with interest on the cash balance at the end of each calendar quarter. The interest rate is equal to the rate of interest payable by us on our revolving credit facility, as determined as of the first day of each calendar quarter.

The deferred stock account will be credited with stock dividends (or with cash dividends that are converted to deferred stock credits pursuant to the plan.)

Distribution of a director’s cash and stock accounts will begin on January 15 of the year following the directors’ termination of all services with us. Distributions from the deferred stock account will be made in cash. Distribution will either be made in a lump-sum payment or in up to five consecutive installments as elected by the director.

Individual Option Grants.We have entered into various option agreements with non-employee directors, advisors and other parties in connection with providing certain services, acquisitions and other matters. Such options have various vesting schedules and exercise prices and have been included in the equity compensation plan table above.
