ITEM 1. BUSINESS

The Internet website address of EMCOR Group, Inc. ("EMCOR" or the "Company") is http://www.emcorgroup.com. The Company's annual report on Form 10-K, quarterly reports on Forms 10-Q and current reports on Forms 8-K (and any amendments to those reports) are available free of charge on or through its Internet website as soon as reasonably practicable after such material is electronically filed with or furnished to the Securities and Exchange Commission.

GENERAL

EMCOR is one of the largest mechanical and electrical construction and facilities services firms in the United States, Canada, the United Kingdom and in the world. In 2003, EMCOR had revenues of approximately $4.53 billion. EMCOR provides services to a broad range of commercial, industrial, utility, and institutional customers through approximately 70 principal operating subsidiaries, joint ventures and a majority-owned interest in a limited liability company in the United States. EMCOR has offices in 38 states and the District of Columbia in the United States, eight provinces in Canada and 15 primary locations in the United Kingdom. In the United Arab Emirates and South Africa, EMCOR carries on business through joint ventures. EMCOR's executive offices are located at 301 Merritt Seven Corporate Park, Norwalk, Connecticut 06851-1060, and its telephone number at those offices is (203) 849-7800.

EMCOR specializes in providing construction services relating to mechanical and electrical systems in facilities of all types and in providing comprehensive services for the operation, maintenance and management of substantially all aspects of such facilities, commonly referred to as "facilities services."

EMCOR designs, integrates, installs, starts up, operates and maintains various electrical and mechanical systems, including:

o Systems for generation and distribution of electrical power;

o Lighting systems;

o Low-voltage systems, such as fire alarm, security, communications and process control systems;

o Voice and data communications systems;

o Heating, ventilation, air conditioning, refrigeration and clean-room process ventilation systems; and

o Plumbing, process and high-purity piping systems.

EMCOR's facilities services businesses, which support the operation of a customer's facilities, include:

o Site-based operations and maintenance;

o Mobile maintenance and services;

o Facilities management;

o Remote monitoring;

o Installation and support for building systems;

o Technical consulting and diagnostic services;

o Small modification and retrofit projects; and

o Program development and management for energy systems.

These facilities services are provided to a wide range of commercial, industrial, utility and institutional facilities, including those at which EMCOR provided construction services and others at which services were provided by others. EMCOR's varied facilities services are frequently combined to provide integrated service packages which include operations and maintenance, mobile services and facility improvement programs.

EMCOR provides construction services and facilities services directly to corporations, municipalities and other governmental entities, owners/developers and tenants of buildings. It also provides these services indirectly by acting as a subcontractor to general contractors, systems suppliers and other subcontractors. Worldwide, EMCOR employs approximately 26,000 people.

EMCOR's revenues are derived from many different customers in numerous industries which have operations in several different geographical areas. Of EMCOR's 2003 revenues, approximately 80% were generated in the United States and approximately 20% were generated internationally. In 2003, approximately 50% of revenues were derived from new construction projects, 28% were derived from renovation and retrofit of customer's existing facilities and 22% were derived from facilities services operations.

THE BUSINESS

The broad scope of EMCOR's operations are more particularly described below. For information regarding the revenues, operating income and total assets of each of EMCOR's segments with respect to each of the last three fiscal years, and EMCOR's revenues and assets attributable to the United States, Canada, the United Kingdom and all other foreign countries, see Note M to EMCOR's financial statements included herein.

MECHANICAL AND ELECTRICAL CONSTRUCTION SERVICES AND FACILITIES SERVICES

EMCOR believes that the mechanical and electrical construction services and facilities services business is highly fragmented, consisting of thousands of small companies across the United States and around the world. Because EMCOR has total assets, annual revenues, net worth, access to bank credit and surety bonding, and expertise significantly greater than most of its competitors, EMCOR believes it has a significant competitive advantage. The mechanical and electrical construction services industry has a higher growth rate than the overall non-residential construction industry, due principally to the ever increasing content and complexity of mechanical and electrical systems in all types of projects. This increasing content and complexity is, in part, a result of the expanded use of computers and more technologically advanced voice and data communications, lighting, and environmental control systems in all types of facilities. For these reasons, buildings of all types consume more electricity per square foot than in the past and thus need more extensive electrical distribution systems. In addition, advanced voice and data communication systems require more sophisticated power supplies and extensive low voltage and fiber-optic communications cabling. Moreover, the need for greater environmental controls within a building, such as the heightened need for climate control to maintain extensive computer systems at optimal temperatures, and the growing demand for environmental control in individual spaces, have created expanded opportunities for the mechanical and electrical construction services and facilities services business.

Mechanical and electrical construction services primarily involve the design, integration, installation and start-up of: (1) systems for the generation and distribution of electrical power, including power cables, conduits, distribution panels, transformers, generators, uninterruptible power supply systems and related switch gear and controls; (2) lighting systems, including fixtures and controls; (3) low-voltage systems, including fire alarm, security, and process control systems; (4) voice and data communications systems, including fiber-optic and low-voltage copper cabling; (5) heating, ventilation, air conditioning, refrigeration and clean-room process ventilation systems; and (6) plumbing, process and high-purity piping systems.

Mechanical and electrical construction services generally fall into one of two categories: (1) large installation projects with contracts often in the multi-million dollar range that involve construction of industrial and commercial buildings and institutional and public works facilities or the fit-out of large blocks of space within commercial buildings and (2) smaller installation projects typically involving fit-out, renovation and retrofit work.

EMCOR's United States mechanical and electrical construction services operations accounted for about 61% of its 2003 revenues, of which revenues approximately 67% was related to new construction and approximately 33% was related to renovation and retrofit projects. EMCOR provides mechanical and electrical construction services for both large and small installation and renovation projects. Its largest projects include those (1) for institutional use (such as water and wastewater treatment facilities, hospitals, correctional facilities, schools and research laboratories); (2) for industrial use (such as pharmaceutical plants, steel, pulp and paper mills, chemical, automotive and semiconductor manufacturing facilities, and oil refineries); (3) for transportation projects (such as highways, airports and transit systems); (4) for commercial use (such as office buildings, data centers, hotels, casinos, convention centers, sports stadiums, shopping malls and resorts); and (5) for power generation and energy management projects. EMCOR's largest projects, which typically range in size from $10.0 million up to and occasionally exceeding $50.0 million and are usually multi-year projects, represented about 30% of EMCOR's construction services revenues in 2003.

EMCOR's projects of less than $10.0 million accounted for approximately 70% of 2003 construction services revenues. These projects are typically completed in less than one year. They usually involve mechanical and electrical construction services when an end-user or owner undertakes construction or modification of a facility to accommodate a specific use. These projects frequently require mechanical and electrical systems to meet special needs such as critical systems power supply, special environmental controls and high-purity air systems, sophisticated electrical and mechanical systems for data centers, including those associated with internet service providers and electronic commerce, trading floors in financial services businesses, new production lines in manufacturing plants, and office arrangements in existing office buildings. They are not usually dependent upon the new construction market. Demand for these projects and types of services is often prompted by the expiration of leases, changes in technology or changes in the customer's plant or office layout in the normal course of a customer's business.

EMCOR performs its services pursuant to contracts with owners, such as corporations, municipalities and other governmental entities, general contractors, systems suppliers, construction managers, developers, other subcontractors and tenants of commercial properties. Institutional and public works projects are frequently long-term complex projects that require significant technical and management skills and the financial strength to obtain bid and performance bonds, which are often a condition to bidding for and winning these projects.

EMCOR also installs and maintains lighting for streets, highways, bridges and tunnels, traffic signals, computerized traffic control systems, and signal and communication systems for mass transit systems in several metropolitan areas. In addition, in the United States, EMCOR manufactures and installs sheet metal air handling systems for both its own mechanical construction operations and for unrelated mechanical contractors. EMCOR also maintains welding and pipe fabrication shops in support of some of its own mechanical operations.

In the early 1990's, the market for facilities services grew rapidly in the United Kingdom as a result of government initiatives. EMCOR's United Kingdom subsidiary expanded its traditional technical service business in response to these opportunities and established a dedicated unit to focus on the facilities services business. This unit currently provides a full range of facilities services to public and private sector customers under multi-year agreements, including the maintenance of British Airways' facilities at Heathrow and Gatwick Airports, GlaxoSmithKline Research Laboratories, and the Jubilee Line Extension of the London Underground. In the United Kingdom, EMCOR also provides facilities services at several BAE Systems manufacturing plants. In addition, the United Kingdom operations provide on-call and mobile service support on a task-order or contract basis, small renovation project work, and installation and maintenance services for data communications and security systems.

In 1997, EMCOR established a subsidiary to expand its facilities services operations in North America patterned on its United Kingdom business. This unit has built on EMCOR's traditional mechanical and electrical services operations, facilities services activities at its mechanical and electrical contracting subsidiaries, and EMCOR's client relationships, as well as acquisitions, to expand the scope of services currently offered and to develop packages of services for customers on a regional, national and global basis.

As a consequence, EMCOR's United States facilities services unit ("EFS") offers a broad range of facilities services, including maintenance and service of mechanical and electrical systems, which EMCOR has historically provided to customers following completion of construction projects, and site-based operations and maintenance, mobile maintenance and service, facilities management, remote monitoring, installation and support for building systems, technical consulting and diagnostic services, small modification and retrofit projects, and program development and management for energy systems.

EMCOR's facilities services are provided to a wide range of commercial, industrial and institutional facilities, including both those for which EMCOR provided construction services and those for which construction services were provided by others. Facilities services are frequently bundled to provide integrated service packages and are provided on a mobile basis or by customer site-based EMCOR employees.

These facilities services, which generated approximately 22% of 2003 revenues, are provided to owners, operators, tenants and managers of all types of facilities both on a contract basis for a specified period of time and on an individual task order basis.

EMCOR has experienced an expansion in the demand for its facilities services which it believes is driven by customers' decisions to focus on their own core competencies, the increasing technical complexity of their facilities and their mechanical, electrical, voice and data and other systems, and the need for increased reliability, especially in mechanical and electrical systems. These trends have led to outsourcing and privatization programs whereby customers in both the private and public sectors seek to contract out those activities that support but are not directly associated with the customer's core business. EFS clients include Fortune 100 companies in information technology, telecommunications, pharmaceuticals, financial services, publishing and manufacturing.

Illustrative of the outsourcing of companies' facilities services is a three-year agreement, expiring June 2005, with Bank One under which EMCOR provides facilities services for approximately 2,200 Bank One facilities encompassing 34.0 million square feet of space in 30 states; its four and one-half year agreement with LAM Research, expiring December 2006 under which EMCOR provides such services to approximately 1 million square feet of laboratory and office space; its three-year agreement with Mattson Technology, Inc., expiring December 2005 under which EMCOR provides integrated services to approximately 800,000 square feet of commercial space; its three and one-half year agreement with Fidelity Investments expiring June 2004 under which EMCOR provides integrated services to approximately 2.5 million square feet of data center space; and its agreements with Hewlett-Packard Company expiring in March and July 2006 under which EMCOR provides integrated services to approximately 20.0 million square feet of commercial space. In April 2000, EMCOR and CB Richard Ellis Inc., a nationwide real estate management company, created a limited liability company, in which EMCOR has a majority interest and principally provides operations and maintenance services to over 10,000 commercial facilities comprising approximately 30.0 million square feet of space. In November 2003, EMCOR acquired the Facility Management Services division of Siemens Building Technologies, Inc., including contracts to provide facilities services to several operating units of Siemens Corporation encompassing 5.0 million square feet of corporate, manufacturing and research space.

In December 2002, EMCOR acquired Consolidated Engineering Services, Inc. ("CES"), a facilities services business, which generated in 2003 revenues in excess of $422.2 million, and which provided services to approximately 9,800 facilities with an aggregate of approximately 277.0 million square feet of space. In Washington D.C., CES is the second largest facilities services provider to the federal government behind the General Services Administration and currently provides services to such preeminent buildings as the National Archives and the Ronald Reagan Building, the second largest government facility after the Pentagon. It currently provides its services in 28 states throughout the Northeast, Midwest, Mid-Atlantic and Southeast. As part of its operations, CES is responsible for (i) the oversight of all or most of a business' facilities operations, including operation and maintenance, (ii) the oversight of logistical processes, (iii) tenant services and management, (iv) servicing upgrade and retrofit of HVAC, electrical, plumbing, and industrial piping and sheet metal systems in existing facilities and (v) diagnostic and solution engineering for building systems and their components.

The deregulation of, and increased competition in, the utility industry, along with government mandates calling for reduced energy consumption by governmental entities, have led to renewed focus on energy costs and conservation measures. These measures typically include energy assessments and engineering studies, retrofit construction to implement energy savings measures, and the implementation of energy savings measures to ensure continued performance. Various subsidiaries of EMCOR participate in energy savings programs, such as an energy conservation project for Washington Mutual, Inc., which evolved from the facilities services provided by EMCOR to Washington Mutual, Inc. EMCOR believes it has the ability to be a single source provider of construction and facilities services required for energy assessment and for design, installation, and operations and maintenance of energy savings measures.

EMCOR believes mechanical and electrical construction services and facilities services activities are complementary, permitting it to offer customers a comprehensive package of services. The ability to offer both construction and facilities services should enhance EMCOR's competitive position with customers. Furthermore, EMCOR's facilities services operations tend to be less cyclical than its construction operations because facilities services are more responsive to the needs of an industry's operational requirements rather than its construction requirements.

COMPETITION

EMCOR believes that the mechanical and electrical construction services business is highly fragmented and competitive. A majority of EMCOR's revenues are derived from projects requiring competitive bids; however, an invitation to bid is often conditioned upon prior experience, technical capability and financial strength. EMCOR competes with national, regional and local companies, many of which are small, owner-operated entities that operate in a limited geographic area. However, there are a few public companies focused on providing mechanical and electrical construction services. EMCOR is one of the largest providers of mechanical and electrical construction services in the United States, Canada, the United Kingdom and in the world. Competitive factors in the mechanical and electrical construction services business include: (1) the availability of qualified and/or licensed personnel; (2) reputation for integrity and quality; (3) safety record; (4) cost structure; (5) relationships with customers; (6) geographic diversity; (7) the ability to control project costs; (8) experience in specialized markets; (9) the ability to obtain surety bonding; (10) adequate working capital; and (11) access to bank credit.

While the facilities services business is also highly fragmented, a number of large corporations such as Johnson Controls, Inc., Fluor Corp., Unicco Service Company, Trammel Crow and Jones Lang LaSalle are engaged in this field. EMCOR's facilities services operations were expanded both through organic growth and acquisitions.

EMPLOYEES

EMCOR presently employs approximately 26,000 people, approximately 71% of whom are represented by various unions pursuant to more than 430 collective bargaining agreements between EMCOR's individual subsidiaries and local unions. EMCOR believes that its employee relations are generally good. None of these collective bargaining agreements are national or regional in scope.

BACKLOG

EMCOR had contract backlog as of December 31, 2003 of approximately $3.0 billion, compared with backlog of approximately $2.9 billion as of December 31, 2002. Backlog is not a term recognized under accounting principles generally accepted in the United States; however, it is a common measurement used in EMCOR's industry. Backlog includes the unrecognized revenue to completion on the total value of existing construction contracts plus unrecognized revenue on existing facilities services contracts to be derived during the immediately succeeding 12 months. Backlog increased by $0.1 billion as of December 31, 2003 compared to December 31, 2002. Backlog attributable to United States construction and facilities services and backlog attributable to Canada and United Kingdom construction and facilities services each increased by approximately $0.05 billion as of December 31, 2003 when compared to December 31, 2002. For the year ended December 31, 2003, EMCOR had approximately $4.53 billion in revenues compared to approximately $3.97 billion in revenues for the year ended December 31, 2002.

ITEM 3. LEGAL PROCEEDINGS

In February 1995, as part of an investigation by the New York County District Attorney's office into the business affairs of a general contractor that did business with EMCOR's subsidiary, Forest Electric Corp. ("Forest"), a search warrant was executed at Forest's executive offices. On July 12, 2000, Forest was served with a Subpoena Duces Tecum to produce certain documents as part of a broader investigation by the New York County District Attorney's office into illegal business practices in the New York City construction industry. Forest has been informed by the New York County District Attorney's office that it and certain of its officers are targets of the investigation. Forest has produced documents in response to the subpoena and intends to cooperate fully with the District Attorney's office investigation as it proceeds.

In December 2001, the Company's Canadian subsidiary Comstock Canada Limited ("Comstock") commenced an action against Atomic Energy of Canada Limited ("AECL") in the Ontario Superior Court of Justice claiming approximately Cdn. $6.0 million (approximately $4.6 million) in connection with Comstock's work on two medical isotope nuclear reactors and associated works at AECL's facility at Chalk River, Ontario. Comstock's claim was for holdback, unpaid change requests, loss of productivity and extended duration costs. AECL filed an amended defense denying Comstock's claim and counterclaimed against Comstock for Cdn. $47.0 million (approximately $36.3 million) claiming fraud and substantial deficiencies in Comstock's performance of work which are alleged to have resulted in the need to replace much of Comstock's work and installed materials and the need to redesign and reinstall various components of the reactor systems. In December 2003, the matter was settled. The settlement provided for a payment of a portion of Comstock's claim by AECL and did not require payment of any damages by Comstock.

On March 14, 2003, John Mowlem Construction plc ("Mowlem") presented a claim in arbitration against EMCOR's United Kingdom subsidiary, EMCOR Drake & Scull Group plc ("D&S"), in connection with a subcontract D&S entered into with Mowlem with respect to a project for the United Kingdom Ministry of Defence at Abbey Wood in Bristol, U.K. Mowlem seeks damages arising out of alleged defects in the D&S design and construction of the mechanical and electrical engineering services for the project. Mowlem's claim is for (pound)39.5 million (approximately $70.5 million), which includes costs allegedly incurred by Mowlem in connection with rectification of the alleged defects, overhead, legal fees, delay and disruption costs related to such defects, and interest on such amounts. The claim also includes amounts in respect of liabilities that Mowlem accepted in connection with a settlement agreement it entered into with the Ministry of Defence and which it claims are attributable to D&S. D&S believes it has good and meritorious defenses to the Mowlem claim. D&S has denied liability and has asserted a counterclaim for approximately (pound)11.6 million (approximately $20.7 million) for certain design, labor and delay and disruption costs incurred by D&S in connection with its subcontract with Mowlem.

EMCOR is involved in other proceedings in which damages and claims have been asserted against it. EMCOR believes it has a number of valid defenses to such proceedings and claims and intends to vigorously defend itself and does not believe that a significant liability will result.

Inasmuch as the proceedings and claims in which EMCOR is involved range from a few thousand dollars to over $70.0 million, the outcome of which cannot be predicted, adverse results could have a material adverse effect on EMCOR's financial position and/or results of operations.

Of these options, executive officers were granted (i) an aggregate amount of 171,100 of such Executive Options on December 14, 2001 (exercisable in full upon grant) with an exercise price of $41.70 per share, (ii) an aggregate amount of 145,700 of such Executive Options on January 2, 2002 with an exercise price of $46.35 per share and (iii) an aggregate amount of 141,335 of such Executive Options on January 2, 2003 with an exercise price of $54.73.

Pursuant to the terms of the Current Employment Agreements, on the first business day of 2004, the executive officers were granted options to purchase an aggregate of 192,398 shares of Company common stock with an exercise price of $43.83 per share. These options are not included in the Table.

Other than those Executive Options granted on December 14, 2001, referred to above, the Executive Options granted vest one-fourth on the grant date, one-fourth on the first anniversary of the grant date, one-fourth on the second anniversary of the grant date and one-fourth on the last business day of the calendar year immediately preceding the third anniversary of the grant date.

Each of the Executive Options granted have a term of ten years from their respective grant dates and an exercise price per share equal to the fair market value of a share of common stock on their respective grant dates.

DIRECTOR OPTIONS

During 2002, each non-employee director of the Company received 2,000 Director Options and in 2003 Mr. Larry J. Bump, upon his election to the Board, received 2,000 Director Options. These options were in addition to the 3,000 options to purchase common stock granted to each non-employee director under the Company's 1995 Non-Employee Directors' Non-Qualified Stock Option Plan, which plan has been approved by the Company's stockholders. The price at which such Director Options are exercisable is equal to the fair market value per share of common stock on the grant date. The exercise price per share of the Director Options is $55.49 per share, except those granted to Mr. Yonker, upon his election to the Board on October 25, 2002, which have an exercise price of $51.75 per share, and those granted to Mr. Bump, upon his election to the Board on February 27, 2003, which have an exercise price of $48.15 per share. All of these options vested in full on the grant date and have a term of ten years from the grant date.

EXECUTIVE STOCK BONUS PLAN

An Executive Stock Bonus Plan (the "Stock Bonus Plan") was adopted by the Board of Directors in October 2000 and amended December 11, 2003. Pursuant to the Stock Bonus Plan, as amended, 25% of the annual bonus earned by each executive officer is automatically credited to him in the form of units ("RSUs") that will subsequently be converted into common stock at a 15% discount from the fair market value of common stock as of the date the annual bonus is determined. The units are to be converted into shares of common stock and delivered to the executive officer on the earliest of (i) the first business day following the day upon which the Company releases to the public generally its results in respect of the fourth quarter of the third calendar year following the year in respect of which the RSUs were granted ("Release Date"), (ii) the executive officer's termination of employment for any reason or (iii) immediately prior to a "change of control" (as defined in the Stock Bonus Plan). In addition, pursuant to the Stock Bonus Plan, each executive officer is permitted at his election to cause all or part of his annual bonus not automatically credited to him in the form of RSUs under the Stock Bonus Plan to be credited to him in the form of units ("Voluntary Units") that will subsequently be converted into common stock at a 15% discount from the fair market value of common stock as of the date the annual bonus is determined. An election to accept Voluntary Units under the Stock Bonus Plan must be made at least six months prior to the end of the calendar year in respect of which the bonus will be payable. These Voluntary Units are to be converted into shares of common stock and delivered to the executive officer on the earliest of (i) the date elected by the executive officer but in no event earlier than the Release Date, (ii) the executive officer's termination of employment or (iii) immediately prior to a "change of control."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION

OVERVIEW

The results of operations for each of the three years ended December 31, 2003, 2002 and 2001 have been impacted by a number of significant trends and events. Results of operations for 2003 compared to 2002 have been positively impacted by the acquisition of the capital stock of Consolidated Engineering Services, Inc. ("CES") from Archstone-Smith operating trust and others on December 19, 2002, and an increase in revenues and income generated by United States facilities services operations and United States transportation infrastructure work. However, the 2003 results compared to 2002 were negatively impacted by: (1) poor performance in the United Kingdom construction operations;
(2) increased competition for, and a related decrease in gross profit margin on, commercial and industrial work in the United States inasmuch as there has been a continuing decline in commercial and industrial work in the United States resulting from the economic recession; (3) reduced private sector spending on small and discretionary projects and repairs and maintenance work resulting from the economic recession; (4) an increase in the percentage of work relating to public sector construction that typically has lower gross profit margins than private sector work; (5) lower than historical gross profit margins on several United States projects as a result of poor contract performance; and (6) reduced labor productivity due to the uncertain job market. (The foregoing factors affecting the United States subsidiaries are hereafter referred to collectively as the "2003 Unfavorable United States Market Conditions").

The 2002 results of operations compared to 2001 were positively impacted by the acquisition on March 1, 2002 of a group of companies (the "Acquired Comfort Companies") from Comfort Systems USA, Inc. ("Comfort") and increased revenues and income from transportation infrastructure work and facilities services contracts. The results of operations for 2002 compared to 2001 were negatively impacted, as described above with respect to 2003, by (1) the economic recession; (2) the beginning of a negative trend in the performance on EMCOR's United Kingdom construction projects; (3) a reduction in "fast-track" projects (i.e. those projects with timetables more accelerated than typical contracts for similar projects) for telecom work and other work in the United States; and (4) a shift to public sector work in the United States which typically results in revenues being recognized over a longer period of time.

13

EMCOR's management recognizes that some of the business challenges it faces are endemic to the construction and facilities services industry. However, EMCOR has made or has under consideration certain strategic changes with respect to its geographic markets and sectors served, including a shift in focus toward more private sector commercial work even if that causes a temporary reduction in revenues until such construction spending increases significantly. Actions already taken include the replacement of the senior management of the United Kingdom operations and reductions in selling, general and administrative expenses in all segments. Such selling, general and administrative expense reductions are expected to continue in 2004. EMCOR expects the demand for HVAC repair and maintenance services to increase starting in the second quarter of 2004, and EMCOR will continue to follow its long-term strategy of increasing revenues from multi-year facilities services contracts. EMCOR's management believes it has positioned the company to benefit from its strategy; however, there is no guarantee that these strategies will result in significantly improved results if economic conditions affecting EMCOR and the construction industry generally do not improve.

HIGHLIGHTS

Revenues for the year ended December 31, 2003 were $4.53 billion, compared to $3.97 billion and $3.42 billion for the years ended December 31, 2002 and 2001, respectively. Net income was $20.6 million for 2003 compared to $62.9 million for 2002 and $50.0 million for 2001. Diluted earnings per share on net income were $1.33 per share for 2003 compared to $4.07 per share for 2002 and $3.40 per share for 2001.

The Consolidated Results of Operations for EMCOR for the year ended December 31, 2002 include the results of operations of the Acquired Comfort Companies and CES from their respective dates of acquisition. EMCOR acquired two additional companies during each of the years 2003 and 2002. See Note C - Acquisitions of Businesses of the notes to consolidated financial statements for additional discussion of these transactions.

OPERATING SEGMENTS

EMCOR has the following reportable segments which provide services associated with the design, integration, installation, startup, operation and maintenance of various systems: (a) United States electrical construction and facilities services (involving systems for generation and distribution of electrical power, lighting systems, low-voltage systems such as fire alarm, security, communications and process control systems and voice and data systems); (b) United States mechanical construction and facilities services (involving systems for heating, ventilation, air conditioning, refrigeration, and clean-room ventilation systems, and plumbing, process and high-purity piping systems); (c) United States facilities services; (d) Canada construction and facilities services; (e) United Kingdom construction and facilities services; and (f) Other international construction and facilities services. The segment "United States facilities services" principally consists of those operations which provide a portfolio of services needed to support the operation and maintenance of customers' facilities (mobile operation and maintenance services, site-based operation and maintenance services, facility planning and consulting services and energy management programs) which services are not related to customers' construction programs. The Canada, United Kingdom and Other international segments perform electrical construction, mechanical construction and facilities services. "Other international construction and facilities services" represents EMCOR's operations outside of the United States, Canada and the United Kingdom (primarily in South Africa and the Middle East during the periods presented).

APPLICATION OF CRITICAL ACCOUNTING POLICIES

The consolidated financial statements are based on the application of significant accounting policies, which require management to make significant estimates and assumptions. EMCOR's significant accounting policies are described in Note B - Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8 of this Form 10-K. There was no initial adoption of any accounting policies during 2003 other than those listed under "New Accounting Pronouncements" below. EMCOR believes that some of the more critical judgment areas in the application of accounting policies that affect the financial condition and results of operations are the impact of changes in the estimates and judgments pertaining to (a) revenue recognition from (i) long term construction contracts for which the percentage of completion method of accounting is used and (ii) services contracts, (b) collectibility or valuation of accounts receivable, (c) insurance liabilities, (d) income taxes and (e) intangible assets.

REVENUE RECOGNITION FROM LONG-TERM CONSTRUCTION CONTRACTS AND SERVICES CONTRACTS

EMCOR believes its most critical accounting policy is revenue recognition from long-term construction contracts for which EMCOR uses the percentage-of-completion method of accounting. Percentage-of-completion accounting is the prescribed method of accounting for long-term contracts in accordance with accounting principles generally accepted in the United States, Statement of Position No. 81-1, "Accounting for Performance of Construction-Type and Certain Production-Type Contracts," and, accordingly, the method used for revenue recognition within EMCOR's industry. Percentage-of-completion for each contract is measured principally by the ratio of costs incurred to date to perform each contract to the estimated total costs to perform such contract at completion. Certain of EMCOR's electrical contracting business units measure percentage-of-completion by the percentage of labor costs incurred to date to perform each contract to the estimated total labor costs to perform such contract at completion. Provisions for the entirety of estimated losses on

14

uncompleted contracts are made in the period in which such losses are determined. Application of percentage-of-completion accounting results in the recognition of costs and estimated earnings in excess of billings on uncompleted contracts in EMCOR's consolidated balance sheets. Costs and estimated earnings in excess of billings on uncompleted contracts reflected in the consolidated balance sheets arise when revenues have been recognized but the amounts cannot be billed under the terms of contracts. Such amounts are recoverable from customers upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. Costs and estimated earnings in excess of billings on uncompleted contracts also include amounts EMCOR seeks or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders in dispute or unapproved as to both scope and price, or other customer-related causes of unanticipated additional contract costs. Such amounts are recorded at estimated net realizable value and take into account factors that may affect the ability to bill and collect amounts billed. As of December 31, 2003 and 2002, costs and estimated earnings in excess of billings on uncompleted contracts included unbilled revenues for unapproved change orders of approximately $43.0 million and $35.9 million, respectively, and for claims of approximately $56.4 million and $53.3 million, respectively. In addition, accounts receivable as of December 31, 2003 and 2002 include claims and contractually billed amounts related to such contracts of approximately $63.1 million and $45.1 million, respectively. Generally, contractually billed amounts will not be paid by the customer to EMCOR until final resolution of related claims. Due to uncertainties inherent in estimates employed in applying percentage-of-completion accounting, estimates may be revised as project work progresses. Application of percentage-of-completion accounting requires that the impact of revised estimates be reported prospectively in the consolidated financial statements.

In addition to revenue recognition for long-term construction contracts, EMCOR recognizes revenues from services contracts as such contracts are performed in accordance with Staff Accounting Bulletin No. 104, "Revenue Recognition, revised and updated" ("SAB 104"). There are two basic types of services contracts: (1) fixed price services contracts which are signed in advance for maintenance, repair and retrofit work over periods typically ranging from one to three years (for which there may be EMCOR employees on a customer's site full time) and (2) services contracts which may or may not be signed in advance for similar maintenance, repair and retrofit work on an as needed basis (frequently referred to as time and material work). Fixed price services contracts are generally performed evenly over the contract period, and, accordingly, revenue is recognized on a pro-rata basis over the life of the contract. Revenues derived from other services contracts are recognized when the services are performed in accordance with SAB 104. Expenses related to all services contracts are recognized as incurred.

ACCOUNTS RECEIVABLE

EMCOR is required to estimate the collectibility of accounts receivable. A considerable amount of judgment is required in assessing the realization of receivables, which assessment factors include the creditworthiness of the customer, EMCOR's prior collection history with the customer and related aging of the past due balances. The provisions for bad debts during 2003, 2002, and 2001 amounted to approximately $11.2 million, $3.4 million and $2.9 million, respectively. The increased provision of $7.8 million for 2003 compared to 2002 primarily relates to the potential non-payment of a customer account receivable of approximately $5.8 million due to the publicly reported financial difficulties of the customer. At December 31, 2003 and 2002, accounts receivable of $1,009.2 million and $965.0 million, respectively, included allowances of $43.7 million and $40.6 million, respectively. Specific accounts receivable are evaluated when EMCOR believes a customer may not be able to meet its financial obligations due to a deterioration of its financial condition or credit ratings or its bankruptcy. The allowance requirements are based on the best facts available and are re-evaluated and adjusted on a regular basis and as additional information is received.

INSURANCE LIABILITIES

EMCOR has deductibles for certain workers' compensation, auto liability, general liability and property claims, has self-insured retentions for certain other casualty claims, and is self-insured for employee-related health care claims. Losses are recorded based upon estimates of the liability for claims incurred and an estimate of claims incurred but not reported. The liabilities are derived from known facts, historical trends and industry averages utilizing the assistance of an actuary to determine the best estimate of these obligations. EMCOR believes its liabilities for these obligations are adequate. However, such obligations are difficult to assess and estimate due to numerous factors, including severity of injury, determination of liability in proportion to other parties, timely reporting of occurrences and effectiveness of safety and risk management programs. Therefore, if actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and would be recorded in the period that the experience becomes known.

INCOME TAXES

EMCOR has net deferred tax assets primarily resulting from deductible temporary differences, which will reduce taxable income in future periods. A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. As of December 31, 2003 and 2002, the total valuation allowance on net deferred tax assets was approximately $2.0 million and $2.1 million, respectively.

INTANGIBLE ASSETS

As of December 31, 2003, EMCOR had goodwill and net identifiable intangible assets (primarily the market value of its backlog, customer relationships and trademarks and tradenames) of $278.0 million and $22.2 million, respectively, arising out of the acquisition of companies. The determination of related estimated useful lives for identifiable intangible assets and whether those assets are impaired involves significant judgments based upon short and long-term projections of future performance. These forecasts reflect assumptions regarding the ability to successfully integrate acquired companies. Statement of Financial Accounting Standards No. 142, "Goodwill and

15

Other Intangible Assets" ("SFAS 142") requires goodwill to be tested for impairment, on at least an annual basis, and be written down when impaired, rather than amortized as previous standards required. Furthermore, SFAS 142 requires identifiable intangible assets other than goodwill to be amortized over their useful lives unless these lives are determined to be indefinite. Changes in strategy and/or market conditions may result in adjustments to recorded intangible asset balances. As of December 31, 2003, no indicators of impairment of its goodwill or identifiable intangible assets resulted from EMCOR's annual impairment review, which was performed in accordance with the provisions of SFAS
142. See Note B - Summary of Significant Accounting Policies of the notes to consolidated financial statements for additional discussion of the provisions of SFAS 142.

DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS

The reportable segments reflect, in all years presented, reclassifications of certain business units among the segments due to changes in EMCOR's internal reporting structure.

REVENUES

As described below in more detail, revenues for the year ended December 31, 2003 increased 14.3% to $4.53 billion compared to $3.97 billion for 2002. The $566.6 million increase in revenues for 2003 when compared to 2002 was primarily due to revenues of $508.4 million from companies acquired in 2003 and 2002 and to increased revenues in the United States electrical construction and facilities services and United States facilities services segments (excluding acquisitions) of $85.1 million and $19.7 million, respectively. The increases in revenues were partially offset by decreased revenues for the United States mechanical construction and facilities services segment (excluding acquisitions). Revenues for 2002 of $3.97 billion represented a 16.0% increase over revenues of $3.42 billion for 2001. This $548.2 million increase in revenues for 2002 compared to 2001 was primarily due to revenues of $502.6 million from companies acquired in 2002 and to increased revenues related to site-based facilities services contracts and power generation projects. Partially offsetting these increases was a reduction, when compared to 2001, of revenues related to fast-track telecom and other commercial contracts, as well as a shift to longer-term projects which typically result in revenue being recognized over a longer period of time.

The following table presents EMCOR's revenues by operating segment and the approximate percentages of total revenues for the years ended December 31, 2003, 2002 and 2001 (in millions, except for percentages):

Revenues for EMCOR's United States electrical construction and facilities services segment for 2003 increased by $87.1 million compared to 2002. The increase in revenues was primarily due to an increase in transportation infrastructure and energy generation work, partially offset by a significant decline in private sector commercial work, which include offices, manufacturing facilities and hotels. Compared to 2002, the New York City area market in 2003 experienced the largest reduction in revenues from commercial work; however, this decline in revenues was offset by increased public sector work in the Washington D.C area market, increased transportation infrastructure work in the Denver area and increased power generation and transportation infrastructure work in California. The $182.3 million decrease in 2002 revenues attributable to this segment compared to 2001 was primarily due to a reduction during 2002 in fast-track telecom and other commercial work. During 2002, transportation infrastructure work increased and power generation work remained steady compared to the prior year.

United States mechanical construction and facilities services revenues increased $0.4 million for 2003 compared to 2002. Revenues for 2003 compared to 2002 increased in the education and institutional sectors, partially offset by significantly decreased commercial office, manufacturing and power generation work. In 2003, EMCOR's mid-western markets were particularly negatively impacted by a reduction in outage upgrade and replacement work at manufacturing facilities. In addition, revenues were negatively impacted by declines in small and discretionary projects and repairs and maintenance work caused largely by the cooler than normal summer weather conditions in parts of the United States. The $513.3 million increase in revenues for 2002 compared to 2001 was primarily attributable to $475.2 million of revenues from the Acquired Comfort Companies and increased revenues from power generation work in the northern California market. These increases were partially offset by decreased revenues as a result of the performance of fewer fast-track contracts, particularly in the telecom sector.

United States facilities services revenues, which include those operations that principally provide consulting and maintenance services, increased by $411.2 million for 2003 compared to 2002. The increase in revenues was primarily due to revenues of $387.5 million attributable to the CES acquisition and an increase in site-based facilities services contracts, partially offset by a decline in certain small and discretionary projects due to increased competition resulting in fewer projects awarded to EMCOR. Additionally, a reduction in demand for mobile services, which services had been adversely affected by cooler than normal summer weather conditions in parts of the United States, contributed to a decrease in 2003 revenues. Revenues for 2002 increased by $40.3 million compared to 2001. This increase in revenues was primarily attributable to business development activities resulting in an increase in the number of site-based facilities services contracts and, to a lesser extent, to the acquisition of CES, partially offset by a decline in telecommunications related work.

Revenues of Canada construction and facilities services increased by $30.5 million for 2003 as compared to 2002. The increase in revenues for 2003 was primarily attributable to an increase of $36.7 million caused by a change in the rate of exchange for Canadian dollars to United States dollars due to strengthening of the Canadian dollar. But for the exchange rates, revenues would have decreased due to a temporary scale-back in work on certain long-term power generation projects attributable to customer's project scheduling. The $118.1 million increase in revenues for 2002 compared to 2001 was primarily attributable to the performance of work on certain long-term contracts.

United Kingdom construction and facilities services revenues increased $37.4 million for 2003 compared to 2002 principally due to an increase of $47.5 million caused by a change in the rate of exchange for British pounds to United States dollars due to strengthening of the British pound. As was the case in Canada, but for exchange rates, revenues would have declined because of execution of a planned reduction in bidding for certain types of institutional and government-sponsored construction projects. The $70.3 million increase in 2002 revenues compared to 2001 revenues was principally due to growth in the facilities services market, offsetting a decline in the overall construction market. The decline in the overall construction market principally resulted in fewer attractive bid opportunities in 2002, which caused EMCOR to be more selective in submitting project bids.

Other international construction and facilities services revenues primarily consist of EMCOR's operations in the Middle East, South Africa and Europe. Revenues from those operations were zero for 2003, zero for 2002 and $11.6 million for 2001. All of the 2003 and 2002 projects in these markets were performed by joint ventures. The results of these joint venture operations are accounted for under the equity method of accounting because EMCOR has less than majority ownership in these joint ventures, is not subject to a majority of the risk of loss from the joint venture's activities and is not entitled to receive a majority of the joint venture's residual returns or both. Accordingly, revenues attributable to such joint ventures are not reflected as revenues in the consolidated financial statements. In 2001, certain European projects were performed entirely by EMCOR subsidiaries, and therefore, revenues were recorded. EMCOR continues to pursue new business selectively in these markets; however, the availability of opportunities has been significantly reduced as a result of local economic factors, particularly in the Middle East.

COST OF SALES AND GROSS PROFIT

The following table presents EMCOR's cost of sales, gross profit, and gross profit as a percentage of revenues for the years ended December 31, 2003, 2002 and 2001 (in millions, except for percentages):

                                                      2003          2002           2001
                                                    --------      --------       --------
Cost of sales .................................     $4,052.2      $3,485.4       $3,028.0
Gross profit ..................................     $  482.5      $  482.6       $  391.8
Gross profit as a percentage of revenues ......         10.6%         12.2%          11.5%

Gross profit decreased $0.1 million for 2003 compared to 2002. Gross profit as a percentage of revenues was 10.6% for 2003 compared with 12.2% for 2002. Gross profit as a percentage of revenues decreased primarily due to poor performance in the United Kingdom construction market and the 2003 Unfavorable United States Market Conditions previously discussed in the Overview above; this decline was offset in part by $93.7 million of gross profit attributable to the companies acquired and their generally higher gross profit as a percentage of revenues than other EMCOR subsidiaries. Gross profit increased $90.8 million for 2002 compared with 2001, and gross profit as a percentage of revenues increased to 12.2% for 2002 compared to 11.5% for 2001. The increase in gross profit was primarily due to gross profit of $81.2 million earned by companies acquired in 2002. An increase in gross profit of $9.6 million in 2002 compared to 2001, which was attributable to EMCOR's other subsidiaries, was due to the type and location of construction and facilities services contracts performed, efficient deployment of local labor, effective procurement of materials and focus on risk management programs. The increase in 2002 when compared to 2001 in gross profit as a percentage of revenues was principally attributable to the Acquired Comfort Companies and their generally higher gross profit as a percentage of revenues than other EMCOR subsidiaries and, to a lesser extent, improvements in gross profit in EMCOR's other subsidiaries due to favorable job close-outs.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

The following table presents EMCOR's selling, general and administrative expenses, and selling, general and administrative expenses as a percentage of revenues, for the years ended December 31, 2003, 2002 and 2001 (in millions, except for percentages):

                                                                                       2003           2002           2001
                                                                                      ------         ------         ------
Selling, general and administrative expenses ...................................      $437.3         $368.2         $303.1
Selling, general and administrative expenses as a percentage of revenues .......         9.6%           9.3%           8.9%

Selling, general and administrative expenses increased $69.1 million between 2003 and 2002. As a percentage of revenues, total selling, general and administrative expenses increased to 9.6% in 2003 as compared to 9.3% in 2002. For 2003, selling, general and administrative expenses included amortization expense of $2.8 million attributable to identifiable intangible assets associated with acquisitions compared to $0.8 million for 2002. Selling, general and administrative expenses (excluding companies acquired in 2003 and 2002 and related amortization expense) were approximately $302.8 million (8.4% of revenues) for 2003 compared to $307.5 million (8.9% of revenues) for 2002, which decrease in selling, general and administrative expenses was attributable to a managed reduction of both variable expenses (including reduced incentive compensation related to less favorable financial performance and reduction in personnel) and fixed expenses (such as building occupancy costs). Selling, general and administrative expenses increased $65.1 million in 2002 compared to 2001. As a percentage of revenues, total selling, general and administrative expenses increased to 9.3% in 2002 as compared to 8.9% in 2001. The increase in expenses and increase in expenses as a percentage of revenues during 2002 as compared to 2001 was primarily due to $61.0 million of expenses attributable to companies acquired in 2002 and increased variable selling, general and administrative expenses of certain other EMCOR subsidiaries (primarily incentive compensation related to more favorable financial performance), which increased expenses were partially offset by a $5.5 million reduction in goodwill amortization expense as goodwill is no longer required to be amortized per SFAS
142. Goodwill amortization expense for the year ended December 31, 2003, 2002 and 2001 was zero, zero and $5.5 million, respectively.

As described below in more detail, operating income decreased by $69.3 million to $45.1 million for 2003 compared to $114.4 million for 2002. This decrease in 2003 was primarily attributable to the 2003 Unfavorable United States Market Conditions previously discussed in the Overview above, and operating losses from the United Kingdom construction and facilities services segment. Operating income was favorably impacted by $4.5 million, $2.3 million and $0.5 million reductions of insurance liabilities previously established for insurance exposures as a consequence of effective risk management and safety programs. Operating income increased by $25.7 million to $114.4 million for 2002 compared to $88.7 million for 2001. This increase in 2002 was primarily attributable to $19.7 million of operating income from acquisitions, increased transportation infrastructure and power generation construction work and the successful completion and settlement of several contracts.

Operating income decreased for the United States electrical construction and facilities services operations for 2003 compared to 2002. The decrease in operating income for 2003 of $21.1 million as compared to 2002, and the related decrease as a percentage of revenues, was primarily attributable to the 2003 Unfavorable United States Market Conditions previously discussed in the Overview above. This decrease was partially offset by profitable performance of transportation infrastructure and certain power generation work. In 2003, the New York City area market was particularly adversely impacted by a significant decline in commercial work and by unprofitable performance of power generation work. Conversely, the Washington, D.C. area market provided a consistent profitable revenue base, the

18

Denver area benefited from increased income from transportation infrastructure work and operations in California benefited from increased income from power generation, transportation infrastructure work and project close-outs. In addition, selling, general and administrative expenses (excluding companies acquired) decreased by approximately $19.1 million in this segment for 2003 compared to 2002. This decrease was mostly related to a reduction in incentive compensation, which related to less favorable financial performance and reduction in personnel, and a reduction in other variable expenses. Operating income for 2002 for the United States electrical construction and facilities services operations increased $3.6 million, or 4.8%, from 2001 levels. The increase in operating income, and operating income as a percentage of revenues, for 2002 versus 2001 was primarily attributable to increased transportation infrastructure work and continuing power generation construction work on the west coast, the successful completion and settlement of several contracts, and increased operating income attributable to various commercial and industrial projects in the San Diego, Las Vegas, Washington D.C. and Denver markets, offset in part, by a reduction in fast-track data center construction work across other markets.

United States mechanical construction and facilities services operating income decreased $34.2 million for 2003 compared to 2002. This decrease in operating income and decrease as a percentage of revenues was primarily due to the 2003 Unfavorable United States Market Conditions previously discussed in the Overview above. The mid-western markets were negatively impacted by a significant reduction in work on manufacturing facilities, the western markets were negatively impacted by reduced income from power generation work and parts of the United States markets were negatively impacted by reduced repairs and maintenance work caused largely by the cooler than normal summer weather conditions. This decrease in operating income was partially offset by increased income from water and wastewater treatment facilities projects for 2003 compared to 2002. In addition, selling, general and administrative expenses decreased by approximately $11.5 million in this segment for 2003 compared to 2002. This decrease was mostly related to a reduction in incentive compensation related to less favorable financial performance and reduction in personnel and reduction in other variable expenses. Operating income for 2002 compared to 2001 increased $17.9 million, and as a percentage of revenues increased to 3.5% from 3.4%, primarily due to (i) operating income of $ 18.7 million from the Acquired Comfort Companies, (ii) operating income associated with power generation construction work in the northern California market and (iii) improved results at the Poole & Kent subsidiary operations which had losses in 2001. The increases were partially offset by reduced operating income attributable to fewer fast-track projects in the 2002 than 2001.

United States facilities services operating income increased by $12.7 million for 2003 compared with 2002. The increase in operating income was primarily attributable to income of $13.5 million from the CES acquisition and an increase in the number of site-based facilities services contracts resulting from business development activities. The increase was partially offset by reduced income from certain small and discretionary projects due to increased competition and from mobile services, which services were adversely affected by cooler than normal summer weather conditions in parts of the United States. Operating income of $4.3 million in this segment for 2002 compared to operating losses of $7.2 million for 2001 increased by $11.5 million primarily due to new facilities services contracts and a decrease in selling, general and administrative expenses as the facilities services operations became more established and required less spending related to the development of new business.

Canada construction and facilities services operating income decreased by $1.3 million in 2003 compared to 2002. This decrease was principally due to (a) increased hospital and school construction projects and less manufacturing outage work, since hospital and school construction projects generally had lower gross profits than the manufacturing outage work performed in 2002, (b) decreased profit from several longer-term power generation projects compared with the prior year and (c) $0.2 million of an increase in operating income relating to the change in exchange rates due to strengthening of the Canadian dollar. For 2002 compared to 2001, operating income increased by $1.0 million principally due to increased work on longer-term contracts that result in profit recognition over an extended time period, partially offset by a reduction in the number of fast-track type contracts.

United Kingdom construction and facilities services operating income decreased by $22.4 million to a reported operating loss in 2003 compared to 2002. The operating loss was primarily attributable to: (1) net unfavorable settlements and closeouts of certain construction projects completed during the year, (2) increased bad debt expense of $5.8 million in 2003 primarily related to the potential non-payment of a large customer account receivable due to publicly reported financial difficulties, (3) reorganization expenses of approximately $2.0 million related to employee severance expenses and the closing of several offices and (4) $1.5 million relating to the change in exchange rates due to strengthening of the British pound. For 2002, operating income decreased by $7.2 million as compared to 2001. This decrease was primarily attributable to unfavorable settlements and closeouts of certain construction projects completed during the year.

Other international construction and facilities services operating income was $0.3 million for 2003 compared to operating losses of $0.1 million and $1.2 million in 2002 and 2001, respectively. EMCOR continues to pursue new business selectively in the Middle Eastern, South African and European markets; however, the availability of opportunities has been significantly reduced as a result of local economic factors, particularly in the Middle East.

General corporate expenses for 2003 increased by $3.4 million from 2002 levels, and increased in 2002 by $2.2 million from 2001 levels. The increase in general corporate expenses for 2003 compared with 2002 was primarily related to an increase in personnel required to support the business growth related to acquisitions and increased marketing expenses associated with EMCOR's brand awareness campaign, which promotes the EMCOR brand on the national and local level in the United States and targets non-traditional buyers of EMCOR services such as chief executive and chief financial officers of companies. The increase for 2002 compared with 2001 was due to the expansion of operations support activities such as information technology infrastructure, human resources and marketing.

19

Interest expense increased by $4.8 million for 2003 compared to 2002 due to increased borrowing under EMCOR's revolving credit facility. Interest expense decreased by $0.7 million in 2002 compared to 2001 principally due to the conversion of $115.0 million of EMCOR's 5.75% Convertible Subordinated Notes into approximately 4.2 million shares of EMCOR common stock in the second quarter of 2001.

Interest income decreased by $1.3 million in 2003 compared to 2002 due to repayment of increased borrowings for working capital under the revolving credit facility. Interest income decreased by $3.6 million in 2002 compared with 2001, which decrease was due to a reduction in cash on hand in 2002 related to cash used for acquisitions and repayment of borrowings related to the acquisitions and to lower interest rates earned.

LIQUIDITY AND CAPITAL RESOURCES

The following table presents EMCOR's net cash provided by (used in) operating activities, investing activities and financing activities for the years ended December 31, 2003 and 2002 (in millions):

                                                           2003          2002

Net cash provided by operating activities ............    $  1.3       $ 154.7
Net cash used in investing activities ................    $(23.3)      $(364.8)
Net cash provided by financing activities ............    $  7.1       $ 113.4

The Company's consolidated cash balance decreased by $14.8 million from $93.1 million at December 31, 2002 to $78.3 million at December 31, 2003. Net cash provided by operating activities for 2003 was $1.3 million, a decrease of $153.4 million from net cash provided by operating activities of $154.7 million for 2002. The decrease in cash provided by operating activities in 2003 compared to 2002 was due to decreased net income, decreased accrued expenses, increased accounts receivable and increased contracts in progress, net, offset by increased accounts payable. The changes in these accounts in 2003, and the related decrease in net cash provided by operating activities, are a result of EMCOR's shift in work toward more public sector work and less small and discretionary projects. The increase in public sector work, which typically involves larger projects, lower gross profit margins and more capital than private sector work, was the primary reason for the decrease; the decrease was also due to reduced higher margin small and discretionary projects that requires much less upfront cash than large construction projects. Net cash used in investing activities in 2003 of $23.3 million consisted primarily of payments of an aggregate of $8.9 million for acquisitions in 2003 and earn-out payments of $2.0 million for acquisitions in prior periods, net disbursements for other investments of $1.8 million and $17.9 million for purchases of property, plant and equipment, offset by $5.2 million of payments received pursuant to indemnity provisions of acquisition agreements. This activity compares to net cash used in investing activities for 2002, which consists primarily of aggregate payments of $334.7 million for acquisitions in 2002 and earn-out payments of $8.7 million for acquisitions from prior periods, net disbursements for other investments of $7.7 million and $15.6 million for the purchase of property, plant and equipment. Net cash provided by financing activities for 2003 of $7.1 million was primarily attributable to net borrowings under working capital credit lines of $27.4 million and proceeds from the exercise of stock options of $2.0 million, offset by repayments of long-term debt of $22.2 million.

The following is a summary of EMCOR's material contractual obligations and other commercial commitments (in millions):

(1) Represent open purchase orders for material and subcontracting costs related to the Company's construction and service contracts. These purchase orders are not reflected in EMCOR's consolidated balance sheet and should not impact future cash flows as amounts will be recovered through customer billings.

(2) Represent primarily insurance related liabilities, the timing for which payments beyond one year is not practical to estimate.

(3) EMCOR classifies these borrowings as short-term on its consolidated balance sheet because of EMCOR's intent and ability to repay the amounts on a short-term basis.

On September 26, 2002, EMCOR entered into a $275.0 million five year revolving credit agreement (the "Revolving Credit Facility"). Effective July 9, 2003, EMCOR increased its borrowing capacity under the Revolving Credit Facility to $350.0 million. The Revolving Credit Facility, which replaced a credit facility entered into on December 22, 1998, is guaranteed by certain direct and indirect subsidiaries of EMCOR, is secured by substantially all of the assets of EMCOR and most of its subsidiaries, and provides for borrowings in the form of revolving loans and letters of credit. The Revolving Credit Facility contains various covenants requiring, among other things, maintenance of certain financial ratios and certain restrictions with respect to payment of dividends, common stock repurchases, investments, acquisitions, indebtedness and capital expenditures. A commitment fee is payable on the average daily unused amount of the Revolving Credit Facility. The fee ranges from 0.3% to 0.5% of the unused amount, based on certain financial tests. Loans under the Revolving Credit Facility bear interest at (1) a rate which is the prime commercial lending rate announced by Harris Nesbitt from time to time (4.0% at December 31, 2003) plus 0% to 1.0%, based on certain financial tests, (2) United States dollar LIBOR (at December 31, 2003 the rate was 1.16%) plus 1.5% to 2.5%, based on certain financial tests or (3) British pound LIBOR (at December 31, 2003 the rate was 3.91%) plus 1.5% to 2.5%, based on certain financial tests. The interest rates in effect at December 31, 2003 were 4.25%, 2.91% and 5.66% for the prime commercial lending rate, United States dollar LIBOR and British pound LIBOR, respectively. Letter of credit fees issued under this facility range from 0.75% to 2.5% of the respective face amounts of the letters of credit issued and are charged based on the type of letter of credit issued and certain financial tests. As of December 31, 2003 and 2002, EMCOR had approximately $49.2 million and $39.9 million of letters of credit outstanding, respectively. EMCOR had borrowings of $139.4 million and $112.0 million outstanding under the Revolving Credit Facility at December 31, 2003 and 2002, respectively.

In August 2001, the Company's Canadian subsidiary, Comstock Canada Ltd., renewed a credit agreement with a bank providing for an overdraft facility of up to Cdn. $0.5 million. The facility is secured by a standby letter of credit and provides for interest at the bank's prime rate (4.5% at December 31, 2003). There were no borrowings outstanding under this credit agreement at December 31, 2003 or 2002.

A subsidiary of EMCOR has guaranteed indebtedness of a venture in which it has a 40% interest; the other venture partner, Baltimore Gas and Electric, has a 60% interest. The venture designs, constructs, owns, operates, leases and maintains facilities to produce chilled water for sale to customers for use in air conditioning commercial properties. These guarantees are not expected to have a material effect on EMCOR's financial position or results of operations. Each of the venturers is jointly and severally liable, in the event of default, for the venture's $25.0 million borrowing due December 2031. During September 2002, each venture partner contributed equity to the venture, of which EMCOR's contribution was $14.0 million.

EMCOR is contingently liable to sureties in respect of performance and payment bonds issued by sureties, usually at the request of customers in connection with construction projects which secure EMCOR payment and performance obligations under contracts for such projects. In addition, at the request of labor unions representing certain EMCOR employees, bonds are sometimes provided to secure obligations for wages and benefits payable to or for such employees. EMCOR bonding requirements typically increase as the amount of public sector work increases. As of December 31, 2003, sureties had issued bonds for the account of EMCOR in the aggregate amount of approximately $1.7 billion. The bonds are issued by EMCOR's sureties in return for a premium which varies depending on the size and type of the bonds. The largest individual bond is approximately $170.0 million. EMCOR has agreed to indemnify the sureties for any payments made by them in respect of bonds issued on EMCOR's behalf.

On March 18, 1998, EMCOR sold, pursuant to an underwritten public offering, $115.0 million principal amount of 5.75% Convertible Subordinated Notes. During the second quarter of 2001, EMCOR called its 5.75% Convertible Subordinated Notes for redemption. As a consequence, all of the Convertible Subordinated Notes were converted into approximately 4.2 million shares of EMCOR common stock.

EMCOR does not have any other material financial guarantees or off-balance sheet arrangements other than those disclosed herein.

The primary source of liquidity for EMCOR has been, and is expected to continue to be, cash generated by operating activities. EMCOR also maintains the Revolving Credit Facility that may be utilized, among other things, to meet short-term liquidity needs in the event cash generated by operating activities is insufficient or to enable EMCOR to seize opportunities to participate in joint ventures or to make acquisitions that may require access to cash on short notice or for any other reason. EMCOR may also increase liquidity through an equity offering or other debt instruments. Short-term changes in macroeconomic trends may have an effect, positively or negatively, on liquidity. In addition to managing borrowings, EMCOR's focus on the facilities services market is intended to provide an additional buffer against economic downturns as the facilities services market is characterized by annual and multi-year contracts that provide a more predictable stream of cash flow than the construction market. The acquisition in December 2002 of CES, which is primarily focused on the facilities services market, is part of EMCOR's plan to grow its facilities services business. Short-term liquidity is also impacted by the type and length of construction contracts in place. During economic downturns, such as the 2001 through 2003 period, there are typically fewer small and discretionary projects from the private sector and companies such as EMCOR more aggressively bid more large long-term infrastructure and public sector contracts. Performance of long duration contracts typically require working capital until initial billing milestones are achieved. While EMCOR strives to maintain a net over-billed position with its customers, there can be no assurance that a net over-billed position can be maintained. EMCOR's net over-billings, defined as the balance sheet accounts billings in excess of costs and estimated earnings on uncompleted contracts less cost and estimated earnings in excess of billings on uncompleted contracts, was $95.8 million and $127.3 million as of December 31, 2003 and 2002, respectively.

21

Long-term liquidity requirements can be expected to be met through cash generated from operating activities, the Revolving Credit Facility, and the sale of various secured or unsecured debt and/or equity interests in the public and private markets. Based upon EMCOR's current credit ratings and financial position, EMCOR can reasonably expect to be able to issue long-term debt instruments and/or equity. Over the long term, EMCOR's primary revenue risk factor continues to be the level of demand for non-residential construction services, which is in turn influenced by macroeconomic trends including interest rates and governmental economic policy. In order to provide protection against declines in demands for private sector construction services, EMCOR has increased its participation, and its backlog of contracts, in the public sector and in the facilities services market. In addition to the primary revenue risk factor, EMCOR's ability to perform work at profitable levels is critical to meeting long-term liquidity requirements.

EMCOR believes that current cash balances and borrowing capacity available under the Revolving Credit Facility or other forms of financing available through debt or equity offerings, combined with cash expected to be generated from operations, will be sufficient to provide short-term and foreseeable long-term liquidity and meet expected capital expenditure requirements. However, EMCOR is a party to lawsuits and other proceedings in which other parties seek to recover from it amounts ranging from a few thousand dollars to over $70.0 million. If EMCOR was required to pay damages in one or more such proceedings, such payments could have a material adverse effect on its financial position, results of operations and/or cash flows.

CERTAIN INSURANCE MATTERS

As of December 31, 2003, EMCOR utilized approximately $37.7 million of letters of credit issued pursuant to its Revolving Credit Facility as collateral for its insurance obligations.

NEW ACCOUNTING PRONOUNCEMENTS

In January 2003, the FASB issued Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure" ("SFAS 148"). SFAS 148 amends FASB Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123") to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS 148 amends the disclosure requirements of SFAS 123 to require prominent disclosures in both annual and interim financial statements of the method of accounting for stock-based employee compensation and the effect of the method used on reported results. SFAS 148 is effective for fiscal years beginning after December 15, 2002 and was adopted by EMCOR for all periods presented herein. EMCOR has not changed to the fair value based method of accounting for stock-based employee compensation; therefore, adoption of SFAS 148 has impacted disclosures, not the financial results, of EMCOR.

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities" (revised December 2003) ("FIN 46"). FIN 46 expands upon and strengthens existing accounting guidance that addresses when a company should include in its financial statements the assets, liabilities and activities of another entity. A variable interest entity is a corporation, partnership, trust, or any other legal structure used for business purposes in which: (1) the equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support provided by any parties, including the equity holders; (2) the equity investors lack one or more of the following essential characteristics of a controlling financial interest: (a) the direct or indirect ability to make decisions about the entity's activities through voting rights or similar rights, (b) the obligation to absorb the expected losses of the entity or (c) the right to receive the expected residual returns of the entity; or (3) the equity investors have voting rights that are not proportionate to their economic interests, and the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest . FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity's activities or is entitled to receive a majority of the entity's residual returns or both. FIN 46 is effective for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period ending after March 15, 2004 (except for special purpose entities for which the effective date is periods ending after December 31, 2003). EMCOR has determined that the adoption of the provisions of FIN 46 has had no effect on EMCOR's consolidated financial condition or results of operations.

In May 2003, the FASB issued Statement of Financial Accounting Standards No. 150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity" ("SFAS 150"). SFAS 150 requires certain financial instruments that embody obligations of the issuer and have characteristics of both liabilities and equity to be classified as liabilities. The provisions of SFAS 150 are effective for financial instruments entered into or modified after May 31, 2003 and to all other instruments that exist as of the beginning of the first interim financial reporting period beginning after June 15, 2003. EMCOR does not have any financial instruments that meet the provisions of SFAS 150; therefore, EMCOR has determined that the provisions of SFAS 150 have had no effect on EMCOR's consolidated financial position, results of operations or cash flows.

In December 2003, the FASB issued Statement of Financial Accounting Standards No. 132 (revised 2003), "Employers' Disclosure about Pensions and Other Postretirement Benefits" ("SFAS 132"). SFAS 132 replaces the disclosure requirements in Statement of Financial Accounting Standard No 87, "Employers' Accounting for Pensions," Statement of Financial Accounting Standard No. 88, "Employers' Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits," and Statement of Financial

22

Accounting Standard No. 106, "Employers' Accounting for Postretirement Benefits Other than Pensions." This revised statement retains the original disclosure requirements of SFAS 132. It requires additional disclosures to those in the original SFAS 132 about assets, obligations, cash flows and net periodic benefit cost of defined benefit plans and other defined postretirement plans. SFAS 132 is effective for interim periods and fiscal years ending after December 15, 2003. EMCOR has adopted the revised provisions of SFAS 132 effective December 31, 2003.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

EMCOR has not used derivative financial instruments for any purpose during the years ended December 31, 2003 and 2002, including trading or speculating on changes in interest rates, or commodity prices of materials used in its business.

EMCOR is exposed to market risk for changes in interest rates for borrowings under the Revolving Credit Facility. Borrowings under that facility bear interest at variable rates, and the fair value of this borrowing is not significantly affected by changes in market interest rates. As of December 31, 2003, there was $139.4 million of borrowings outstanding under the facility, and these borrowings bear interest at (1) a rate which is the prime commercial lending rate announced by Harris Nesbitt from time to time (4.0% at December 31, 2003) plus 0% to 1.0%, based on certain financial tests or (2) United States dollar LIBOR (at December 31, 2003 1.16%) plus 1.5% to 2.5%, based on certain financial tests or (3) British pound LIBOR (at December 31, 2003 3.91%) plus 1.5% to 2.5%, based on certain financial tests. Based on the borrowings outstanding of $139.4 million, if the overall interest rates were to increase by 1.0%, the net of tax interest expense would increase approximately $0.8 million in the next twelve months. Conversely, if the overall interest rates were to decrease by 1.0%, interest expense would decrease by approximately $0.8 million in the next twelve months. The Revolving Credit Facility expires in September 2007. There is no guarantee that EMCOR will be able to renew the facility at its expiration.

EMCOR is also exposed to market risk and the market's potential related impact on accounts receivable or costs and estimated earnings in excess of billings on uncompleted contracts. The amounts recorded may be at risk if customers' ability to pay these obligations is negatively impacted by economic conditions. EMCOR continually monitors the credit worthiness of its customers and maintains on-going discussions with customers regarding contract status with respect to change orders and billing terms. Therefore, EMCOR believes it takes appropriate action to manage market and other risks, but there is no assurance that it will be able to reasonably identify all risks with respect to collectibility of these assets. See also the previous discussion of Accounts Receivable under the heading "Application of Critical Accounting Policies" in the Management's Discussion and Analysis of Results of Operations and Financial Condition.

Amounts invested in EMCOR's foreign operations are translated into U. S. dollars at the exchange rates in effect at year end. The resulting translation adjustments are recorded as accumulated other comprehensive income (loss), a component of stockholders' equity, in its consolidated balance sheets. EMCOR believes the exposure to the effects that fluctuating foreign currencies may have on its consolidated results of operations is limited because the foreign operations primarily invoice customers and collect obligations in their respective local currencies. Additionally, expenses associated with these transactions are generally contracted and paid for in their same local currencies.

EMCOR GROUP, INC.
AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A -- NATURE OF OPERATIONS

EMCOR Group, Inc., a Delaware corporation, and subsidiaries (collectively "EMCOR") is one of the largest mechanical and electrical construction and facilities services firms in the United States, Canada, the United Kingdom and in the world. EMCOR specializes in providing services relating to mechanical and electrical systems in facilities of all types and in providing comprehensive services for the operation, maintenance and management of substantially all aspects of such facilities, commonly referred to as "facilities services." EMCOR designs, integrates, installs, starts up, operates and maintains various electrical and mechanical systems, including: (1) systems for the generation and distribution of electrical power; (2) lighting systems; (3) low-voltage systems, such as fire alarm, security, communication and process control systems; (4) voice and data communications systems; (5) heating, ventilation, air conditioning, refrigeration and clean-room process ventilation systems; and (6) plumbing, process and high-purity piping systems. EMCOR provides mechanical and electrical construction services and facilities services directly to corporations, municipalities and other governmental entities, owners/developers and tenants of buildings. It also provides these services indirectly by acting as a subcontractor to general contractors, systems suppliers and other subcontractors. Mechanical and electrical construction services generally fall into one of two categories: (1) large installation projects with contracts often in the multi-million dollar range that involve construction of industrial and commercial buildings and institutional and public works facilities or the fit-out of large blocks of space within commercial buildings and (2) smaller installation projects typically involving fit-out, renovation and retrofit work. EMCOR's facilities services, which are needed to support the operation of a customer's facilities, include site-based operations and maintenance, mobile maintenance and service, facilities management, remote monitoring, small modification and retrofit projects, technical consulting and diagnostic services, installation and support for building systems, and program development and management for energy systems. These services are provided to a wide range of commercial, industrial, utility and institutional facilities including those at which EMCOR provided construction services and others at which construction services were provided by other contractors.

NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of EMCOR and its majority-owned subsidiaries. Significant intercompany accounts and transactions have been eliminated. All investments over which EMCOR exercises significant influence, but does not control (a 20% to 50% ownership interest), are accounted for using the equity method of accounting.

The results of operations for the year ended December 31, 2002 include, from the respective dates of acquisition, the results of a group of companies (the "Acquired Comfort Companies") acquired from Comfort Systems USA, Inc. ("Comfort") on March 1, 2002 and the results of Consolidated Engineering Services, Inc. ("CES") acquired on December 19, 2002. The results of operations of other acquisitions, which are not material, have been included in the results of operations from the date of acquisition by EMCOR.

PRINCIPLES OF PREPARATION

The preparation of the consolidated financial statements, in conformity with accounting principles generally accepted in the United States, requires EMCOR to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Reclassifications of prior years data have been made in the accompanying consolidated financial statements where appropriate to conform to the current presentation.

REVENUE RECOGNITION

Revenues from long-term construction contracts are recognized on the percentage-of-completion method. Percentage-of-completion is measured principally by the percentage of costs incurred to date for each contract to the estimated total costs for such contract at completion. Certain of EMCOR's electrical contracting business units measure percentage-of-completion by the percentage of labor costs incurred to date for each contract to the estimated total labor costs for such contract. Revenues from services contracts are recognized as services are provided. There are two basic types of services contracts: (1) fixed price facilities services contracts which are signed in advance for maintenance, repair and retrofit work over periods typically ranging from one to three years (for which there may be EMCOR employees on the customer's site full time) and (2) services contracts which may or may not be signed in advance for similar maintenance, repair and retrofit work on an as needed basis (frequently referred to as time and material work). Fixed price services contracts are generally performed evenly over the contract period, and, accordingly, revenue is recognized on a pro-rata basis over the life of the contract. Revenues derived from other services contracts are recognized when the services are performed in accordance with Staff Accounting Bulletin No. 104, "Revenue Recognition, revised and updated." Expenses related to all services contracts are recognized as incurred.

NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

Provisions for estimated losses on uncompleted long-term contracts are made in the period in which such losses are determined. In the case of customer change orders for uncompleted long-term construction contracts, estimated recoveries are included for work performed in forecasting ultimate profitability on certain contracts. Due to uncertainties inherent in the estimation process, it is reasonably possible that completion costs, including those arising from contract penalty provisions and final contract settlements, will be revised in the near-term. Such revisions to costs and income are recognized in the period in which the revisions are determined.

COSTS AND ESTIMATED EARNINGS ON UNCOMPLETED CONTRACTS

Costs and estimated earnings in excess of billings on uncompleted contracts arise when revenues have been recorded but the amounts cannot be billed under the terms of the contracts. Such amounts are recoverable from customers upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of the contract. Also included in costs and estimated earnings on uncompleted contracts are amounts EMCOR seeks or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders in dispute or unapproved as to scope or price, or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). These amounts are recorded at their estimated net realizable value when realization is probable and can be reasonably estimated. No profit is recognized on the construction costs incurred in connection with these amounts. Claims and unapproved change orders made by EMCOR involve negotiation and, in certain cases, litigation. In the event litigation costs are incurred by EMCOR in connection with claims or unapproved change orders, such litigation costs are expensed as incurred; although, EMCOR may seek to recover these costs. EMCOR believes that it has established legal bases for pursuing recovery of its recorded unapproved change orders and claims, and it is management's intention to pursue and litigate such claims, if necessary, until a decision or settlement is reached. Unapproved change orders and claims also involve the use of estimates, and it is reasonably possible that revisions to the estimated recoverable amounts of recorded claims may be made in the near-term. If EMCOR does not successfully resolve these matters, a net expense (recorded as a reduction in revenues), may be required, in addition to amounts that have been previously provided for. Claims against EMCOR are recognized when a loss is considered probable and amounts are reasonably determinable.

Costs and estimated earnings on uncompleted contracts and related amounts billed as of December 31, 2003 and 2002 were as follows (in thousands):

As of December 31, 2003 and 2002, costs and estimated earnings in excess of billings on uncompleted contracts included unbilled revenues for unapproved change orders of approximately $43.0 million and $35.9 million, respectively, and for claims of approximately $56.4 million and $53.3 million, respectively. In addition, accounts receivable as of December 31, 2003 and 2002 include claims and contractually billed amounts related to such contracts of approximately $63.1 million and $45.1 million, respectively. Generally, contractually billed amounts will not be paid by the customer to EMCOR until final resolution of related claims. Included in the claims amount is approximately $31.2 million and $38.7 million as of December 31, 2003 and 2002, respectively, related to projects of EMCOR's Poole & Kent subsidiary, which had commenced prior to EMCOR's acquisition of Poole & Kent in 1999.

NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

CLASSIFICATION OF CONTRACT AMOUNTS

In accordance with industry practice, EMCOR classifies as current all assets and liabilities related to the performance of long-term contracts. The contracting cycle for certain long-term contracts may extend beyond one year, and, accordingly, collection or payment of amounts related to these contracts may extend beyond one year. Accounts receivable at December 31, 2003 and 2002 included $189.5 million and $172.1 million, respectively, of retainage billed under terms of the contracts. EMCOR estimates that approximately 88% of retainage recorded at December 31, 2003 will be collected during 2004.

CASH AND CASH EQUIVALENTS

For purposes of the consolidated financial statements, EMCOR considers all highly liquid instruments with original maturities of three months or less to be cash equivalents. EMCOR maintains a centralized cash management program whereby its excess cash balances are invested in high quality, short-term money market instruments, which are considered cash equivalents. At times, cash balances in EMCOR's bank accounts may exceed federally insured limits.

INVENTORIES

Inventories, which consist primarily of construction materials, are stated at the lower of cost or market. Cost is determined principally using the average cost method. Inventories decreased by $2.4 million to $9.9 million at December 31, 2003 compared to $12.3 million at December 31, 2002.

INVESTMENTS, NOTES AND OTHER LONG-TERM RECEIVABLES

Investments, notes and other long-term receivables at December 31, 2003 were $26.5 million compared to $24.6 million at December 31, 2002, and primarily consist of investments in joint ventures accounted for using the equity method of accounting. Included as investments, notes and other long-term receivables were investments of $18.9 million and $19.4 million as of December 31, 2003 and 2002, respectively, relating to a venture with Baltimore Gas & Electric. This joint venture designs, constructs, owns, operates, leases and maintains facilities to produce chilled water for use in air conditioning commercial properties.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment is stated at cost. Depreciation, including amortization of assets under capital leases, is recorded principally using the straight-line method over estimated useful lives ranging from 2 to 40 years. As events and circumstances indicate, EMCOR reviews the carrying amount of property, plant and equipment for impairment. In performing this review for recoverability, long-lived assets are assessed for possible impairment by comparing their carrying values to their undiscounted net pre-tax cash flows expected to result from the use of the asset. Impaired assets are written down to their fair values, generally determined based on their estimated future discounted cash flows. Through December 31, 2003, no adjustment for the impairment of property, plant and equipment carrying value has been required.

Property, plant and equipment in the accompanying Consolidated Balance Sheets consisted of the following amounts as of December 31, 2003 and 2002 (in thousands):

                                                                                                             2003         2002

GOODWILL AND IDENTIFIABLE INTANGIBLE ASSETS

Goodwill at December 31, 2003 and 2002 was approximately $278.0 million and $290.4 million, respectively, and reflects the excess of cost over fair market value of net identifiable assets of companies acquired.

NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

EMCOR has adopted the following accounting standards issued by the Financial Accounting Standards Board ("FASB"): Statement of Financial Accounting Standards No. 141, "Business Combinations" ("SFAS 141") and Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" ("SFAS 142"). SFAS 141 requires that all business combinations be accounted for using the purchase method of accounting and that certain intangible assets acquired in a business combination be recognized as assets apart from goodwill. SFAS 142, which was adopted as of January 1, 2002, requires goodwill to be tested for impairment at least annually. SFAS 142 requires that goodwill be allocated to the reporting units. The fair value of the reporting unit is compared to the carrying amount on an annual basis to determine if there is a potential impairment. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the fair value of the goodwill within the reporting unit is less than the carrying value. The fair value for goodwill is determined based on discounted estimated future cash flows. Furthermore, SFAS 142 requires identifiable intangible assets other than goodwill to be tested for impairment and be amortized over their useful lives unless these lives are determined to be indefinite.

Identifiable intangible assets are comprised of $12.4 million in market value of customer backlog, $7.0 million in market value of customer relationships and $6.4 million in market value of trademarks and tradenames acquired as a result of acquisitions in 2002. The $12.4 million attributable to backlog and $7.0 million attributable to customer relationships are being amortized on a straight-line method over periods from one to seven years. The $6.4 million attributable to trademarks and tradenames is not being amortized as trademarks and tradenames have indefinite lives, but are subject to an annual review for impairment in accordance with Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144"). See Note C - Acquisitions of Businesses for additional information. The following table presents the estimated future amortization expense of identifiable intangible assets (in thousands):

INSURANCE LIABILITIES

EMCOR's insurance liabilities are determined actuarially based on claims filed and an estimate of claims incurred but not yet reported. At December 31, 2003 and 2002, the estimated current portion of undiscounted insurance liabilities of $16.0 million and $9.1 million, respectively, were included in "Other accrued expenses and liabilities" in the accompanying Consolidated Balance Sheets. The estimated non-current portion of the undiscounted insurance liabilities were included in "Other long-term obligations" and at December 31, 2003 and 2002 were $74.6 million and $73.5 million, respectively. EMCOR's insurance liabilities for workers' compensation, auto liability, general liability and property and casualty claims increased $8.0 million, $9.0 million and $2.7 million for the years ended December 31, 2003, 2002 and 2001, respectively, primarily due to increased premiums and estimated liabilities related to the increase in revenues for the corresponding years. These increases are net of $4.5 million, $2.3 million and $0.5 million reductions of insurance liabilities previously established for insurance exposures as a consequence of effective risk management and safety programs for the years ended December 31, 2003, 2002 and 2001, respectively.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying values of EMCOR's financial instruments, which include accounts receivable and other financing commitments, approximate their fair values due primarily to their short-term maturities.

During 2001, EMCOR called for redemption of its $115.0 million 5.75% convertible subordinated notes. As a consequence, all of the convertible subordinated notes were converted into approximately 4.2 million shares of EMCOR common stock.

FOREIGN OPERATIONS

The financial statements and transactions of EMCOR's foreign subsidiaries are maintained in their functional currency and translated into U.S. dollars in accordance with Statement of Financial Accounting Standards No. 52, "Foreign Currency Translation." Translation adjustments have been recorded as Accumulated other comprehensive income (loss), a separate component of Stockholders' equity.

INCOME TAXES

EMCOR accounts for income taxes in accordance with the provisions of Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). SFAS 109 requires an asset and liability approach which requires the recognition of deferred tax assets and deferred tax liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized.

DERIVATIVES AND HEDGING ACTIVITIES

Gains and losses on contracts designated as hedges of net investments in foreign subsidiaries are recognized in the Consolidated Statements of Stockholders' Equity and Comprehensive Income as a component of Accumulated other comprehensive income (loss).

As of December 31, 2003, 2002 and 2001, EMCOR did not have any derivative instruments.

VALUATION OF STOCK OPTION GRANTS

At December 31, 2003, EMCOR has stock-based compensation plans and programs, which are described more fully in Note I - Stock Options and Stock Plans. EMCOR applies Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related interpretations in accounting for its stock options. Accordingly, no compensation cost has been recognized in the accompanying Consolidated Statements of Operations for the years ended December 31, 2003, 2002 and 2001 in respect of stock options granted during those years inasmuch as EMCOR grants stock options at fair market value. Had compensation cost for these options been determined consistent with Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), EMCOR's net income, basic earnings per share ("Basic EPS") and diluted earnings per share ("Diluted EPS") would have been reduced from the following "as reported amounts" to the following "pro forma amounts" (in thousands, except per share amounts):

NEW ACCOUNTING PRONOUNCEMENTS

In January 2003, the FASB issued Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure" ("SFAS 148"). SFAS 148 amends FASB Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123") to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS 148 amends the disclosure requirements of SFAS 123 to require prominent disclosures in both annual and interim financial statements of the method of accounting for stock-based employee compensation and the effect of the method used on reported results. SFAS 148 is effective for fiscal years beginning after December 15, 2002 and was adopted by EMCOR for all periods presented herein. EMCOR has not changed to the fair value based method of accounting for stock-based employee compensation; therefore, adoption of SFAS 148 has impacted disclosures, not the financial results, of EMCOR.

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities" (revised December 2003) ("FIN 46"). FIN 46 expands upon and strengthens existing accounting guidance that addresses when a company should include in its financial statements the assets, liabilities and activities of another entity. A variable interest entity is a corporation, partnership, trust or any other legal structure used for business purposes in which: (1) the equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support provided by any parties, including the equity holders; (2) the equity investors lack one or more of the following essential characteristics of a controlling financial interest: (a) the direct or indirect ability to make decisions about the entity's activities through voting rights or similar rights, (b) the obligation to absorb the expected losses of the entity or (c) the right to receive the expected residual returns of the entity; or (3) the equity investors have voting rights that are not proportionate to their economic interests, and the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest. FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity's activities or is entitled to receive a majority of the entity's residual returns or both. FIN 46 is effective for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period ending after March 15, 2004 (except for special purpose entities for which the effective rate is periods ending after December 15, 2003). EMCOR has determined that the adoption of the provisions of FIN 46 has had no effect on EMCOR's consolidated financial condition or results of operations.

NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

In May 2003, the FASB issued Statement of Financial Accounting Standards No. 150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity" ("SFAS 150"). SFAS 150 requires certain financial instruments that embody obligations of the issuer and have characteristics of both liabilities and equity to be classified as liabilities. The provisions of SFAS 150 are effective for financial instruments entered into or modified after May 31, 2003 and to all other instruments that exist as of the beginning of the first interim financial reporting period beginning after June 15, 2003. EMCOR does not have any financial instruments that meet the provisions of SFAS 150; therefore, EMCOR has determined that the provisions of SFAS 150 have had no effect on EMCOR's consolidated financial position, results of operations or cash flows.

In December 2003, the FASB issued Statement of Financial Accounting Standards No. 132 (revised 2003), "Employers' Disclosure about Pensions and Other Postretirement Benefits" ("SFAS 132"). SFAS 132 replaces the disclosure requirements in Statement of Financial Accounting Standard No 87, "Employers' Accounting for Pensions," Statement of Financial Accounting Standard No. 88, "Employers' Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits," and Statement of Financial Accounting Standard No. 106, "Employers' Accounting for Postretirement Benefits Other than Pensions." This revised statement retains the original disclosure requirements of SFAS 132. It requires additional disclosures to those in the original SFAS 132 about assets, obligations, cash flows and net periodic benefit cost of defined benefit plans and other defined post-retirement plans. SFAS 132 is effective for interim periods and fiscal years ending after December 15, 2003. EMCOR has adopted the revised provisions of SFAS 132 effective December 31, 2003.

NOTE C -- ACQUISITIONS OF BUSINESSES

On March 1, 2002, EMCOR acquired the Acquired Comfort Companies. Accordingly, the Consolidated Results of Operations for EMCOR for the year ended December 31, 2002 include the results of operations for the Acquired Comfort Companies since March 1, 2002. The purchase price paid for the Acquired Comfort Companies was $186.25 million and was comprised of $164.15 million in cash and $22.1 million by assumption of Comfort's notes payable to former owners of certain of the Acquired Comfort Companies. In 2002, pursuant to the terms of the acquisition agreement, an additional $7.1 million of cash purchase price was paid by EMCOR to Comfort subsequent to the acquisition date due to an increase in net assets of the Acquired Comfort Companies between the closing date and an agreed upon pre-closing date. The acquisition was funded with $121.25 million of EMCOR's funds and $50.0 million from borrowings under EMCOR's revolving credit facility. The Acquired Comfort Companies, which are based predominantly in the United States midwest and New Jersey, are active in the installation and maintenance of mechanical systems and the design and installation of process and fire protection systems. Services are provided to a wide variety of industries, including the food processing, pharmaceutical and manufacturing/distribution sectors. During 2003, EMCOR reduced goodwill by $8.4 million upon receipt of $5.2 million in settlement of Comfort's obligations to EMCOR under the indemnity provisions of the acquisition agreement and of $3.2 million of other purchase price adjustments primarily related to deferred income taxes.

On December 19, 2002, EMCOR acquired CES. CES primarily provides a broad array of facilities services, including comprehensive facilities management, operation and maintenance, mobile services, remote monitoring, technical consulting and diagnostic services, and installation and support for building systems. The purchase price paid for CES was $178.0 million, of which $156.0 million was paid from borrowings under EMCOR's revolving credit facility and $22.0 million was paid from EMCOR's funds. During 2003, EMCOR reduced goodwill by $9.4 million inasmuch as EMCOR attributed $11.2 million of the purchase price to CES identifiable intangible assets offset by other final purchase price and allocation adjustments of $1.8 million.

EMCOR acquired two additional companies during each of the years 2003 and 2002 for which EMCOR paid an aggregate of $8.0 million and $3.4 million, respectively.

EMCOR believes the addition of the companies acquired in 2002, which are generally in geographic markets where EMCOR did not have significant presence, will further EMCOR's goal of market and geographic diversification, expansion of its facilities services operations and expansion of its services offerings. Additionally, the acquisitions create more opportunities for EMCOR companies to collaborate on national facilities services contracts. These factors contributed to total goodwill, representing the excess purchase price over the fair value of amounts assigned to the net assets acquired, of $207.9 million in 2003 compared to total preliminary goodwill of $225.8 million in 2002.

During 2003 and 2002, EMCOR paid an aggregate of $2.0 million and $8.6 million in cash, respectively, by reason of earn-out obligations in respect of prior year acquisitions.

These acquisitions were accounted for by the purchase method, and the purchase price has been allocated to the assets acquired and liabilities assumed, based upon the estimated fair values of these assets and liabilities at the dates of acquisition. Goodwill was $278.0 million and $290.4 million at December 31, 2003 and 2002, respectively. There was no goodwill amortization expense for the years ended December 31, 2003 and 2002.

The goodwill of $207.9 million was recorded primarily in the United States mechanical construction and facilities services and United States facilities services reporting units. It is expected that approximately $155.0 million of the goodwill associated with the acquisitions will be deductible for tax purposes. In accordance with SFAS 141 and SFAS 142, goodwill will not be amortized, while certain other intangible assets that have been identified will be subject to amortization over their useful lives. As of December 31, 2003, $22.1 million of notes assumed in connection with the acquisition of the Acquired Comfort Companies had been paid by EMCOR.

Of the total purchase price paid for the acquisitions, approximately $25.8 million has been allocated to identifiable intangible assets, which includes acquired backlog, customer relationships and trademarks and tradenames. Based on an independent valuation of the Acquired Comfort Companies, $3.2 million was allocated to the value of the contract backlog and will be amortized on a straight-line basis over the individual related contract terms and $6.4 million was allocated to trademarks and tradenames and will not be amortized, but subject to an annual impairment test in accordance with SFAS 144. Based on an independent valuation of CES, $9.2 million was allocated to the value of contract backlog and $7.0 million was allocated to customer relationships, and each will be amortized on a straight-line method. The amortization periods range from one to seven years. See also Note B - Summary of Significant Accounting Policies for additional information.

NOTE E -- CURRENT DEBT

2002 CREDIT FACILITY

On September 26, 2002, EMCOR entered into a $275.0 million five year revolving credit agreement (the "Revolving Credit Facility"). Effective July 9, 2003, EMCOR increased its borrowing capacity under the Revolving Credit Facility to $350.0 million. The Revolving Credit Facility, which replaced a credit facility entered into on December 22, 1998, is guaranteed by certain direct and indirect subsidiaries of EMCOR, is secured by substantially all of the assets of EMCOR and most of its subsidiaries, and provides for borrowings in the form of revolving loans and letters of credit. The Revolving Credit Facility contains various covenants requiring, among other things, maintenance of certain financial ratios and certain restrictions with respect to payment of dividends, common stock repurchases, investments, acquisitions, indebtedness and capital expenditures. A commitment fee is payable on the average daily unused amount of the Revolving Credit Facility. The fee ranges from 0.3% to 0.5% of the unused amount, based on certain financial tests. Loans under the Revolving Credit Facility bear interest at (1) a rate which is the prime commercial lending rate announced by Harris Nesbitt from time to time (4.0% at December 31, 2003) plus 0% to 1.0%, based on certain financial tests, (2) United States dollar LIBOR (at December 31, 2003 the rate was 1.16%) plus 1.5% to 2.5%, based on certain financial tests or (3) British pound LIBOR (at December 31, 2003 the rate was 3.91%) plus 1.5% to 2.5%, based on certain financial tests. The interest rates in effect at December 31, 2003 were 4.25%, 2.91% and 5.66% for the prime commercial lending rate, United States dollar LIBOR and British pound LIBOR, respectively. Letter of credit fees issued under this facility range from 0.75% to 2.5% of the respective face amounts of the letters of credit issued and are charged based on the type of letter of credit issued and certain financial tests. As of December 31, 2003 and 2002, EMCOR had approximately $49.2 million and $39.9 million of letters of credit outstanding, respectively. EMCOR had borrowings of $139.4 million and $112.0 million outstanding under the Revolving Credit Facility at December 31, 2003 and 2002, respectively.

FOREIGN BORROWINGS

In August 2001, EMCOR's Canadian subsidiary, Comstock Canada Ltd., renewed a credit agreement with a bank providing for an overdraft facility of up to Cdn. $0.5 million.

There were no borrowings outstanding under this credit agreement at December 31, 2003 or 2002.

NOTES PAYABLE

The Notes Payable of $21.8 million are notes made by Comfort to former owners of certain Acquired Comfort Companies, which notes were assumed by EMCOR in connection with the acquisition. The Notes Payable accrued interest at 10.0% per annum and were paid in full in April 2003.

CAPITALIZED LEASE OBLIGATIONS

See Note K -- Commitments and Contingencies.

OTHER LONG-TERM DEBT

Other long-term debt consists primarily of loans for real estate, office equipment, automobiles and building improvements. The aggregate amount of other long-term debt maturing during the next five years is approximately $0.1 million in each of 2004, 2005, 2006, 2007 and 2008, and $0.1 million thereafter.

CONVERTIBLE SUBORDINATED NOTES

In 1998, EMCOR sold, pursuant to an underwritten public offering, $115.0 million principal amount of 5.75% Convertible Subordinated Notes. During 2001, EMCOR called for redemption its $115.0 million 5.75% Convertible Subordinated Notes and, as a consequence, the Convertible Subordinated Notes were converted into approximately 4.2 million shares of EMCOR common stock.

NOTE G -- INCOME TAXES

EMCOR files a consolidated federal income tax return including all its U.S. subsidiaries. At December 31, 2003, EMCOR had net operating loss carryforwards ("NOLs") for U.S. income tax purposes of approximately $2.5 million, which expire in the year 2019. In addition, at December 31, 2003, EMCORhad NOLs for United Kingdom income tax purposes of approximately $20.7 million, which have no expiration date. The NOLs are subject to review by taxing authorities.

EMCOR adopted Fresh-Start Accounting in connection with EMCOR's bankruptcy reorganization in December 1994. As a result, the tax benefit of any net operating loss carryforwards or net deductible temporary differences, which existed as of December 15, 1994, resulted in a charge to the tax provision (provision in lieu of income taxes) and a credit to capital surplus. These NOLs were substantially utilized as of December 31, 2001. The amount credited to capital surplus was $21.4 million for the year ended December 31, 2001.

The Company has not recorded deferred income taxes on the undistributed earnings of its foreign subsidiaries because of management's intent to indefinitely reinvest such earnings. Upon distribution of these earnings in the form of dividends or otherwise, EMCOR may be subject to U.S. income taxes and foreign withholding taxes. It is not practical; however, to estimate the amount of taxes that may be payable on the eventual remittance of these earnings.

Plan assets of EMCOR's United Kingdom subsidiary pension plan include marketable equity securities in both United Kingdom and United States companies. Debt securities consist mainly of fixed interest bonds.

The investment policies and strategies for plan assets are established to ensure that obligations to beneficiaries of the plan are met, to achieve a reasonable balance between risk, likely return and administration, as well as to maintain funds at a level to meet minimum funding requirements. In order to ensure that an appropriate investment strategy is in place, an analysis of the Plan's assets and liabilities is completed periodically.

EMCOR has employment agreements with its executive officers and certain key management personnel. The employment agreements with executive officers may be terminated by the executive or EMCOR, but if terminated by EMCOR or by its executive officers for good reason (as defined therein), the agreements provide for severance benefits. Certain of the agreements provide the executive officers with certain additional rights if a change of control (as defined therein) of EMCOR occurs.

EMCOR is contingently liable to sureties in respect of performance and payment bonds issued by sureties, usually at the request of customers in connection with construction projects, which secure EMCOR payment and performance obligations under contracts for such projects. In addition, at the request of labor unions representing certain EMCOR employees, bonds are sometimes provided to secure such obligations for wages and benefits payable to or for such employees. EMCOR bonding requirements typically increase as the amount of public sector work increases. As of December 31, 2003, sureties had issued bonds for the account of EMCOR in the aggregate amount of approximately $1.7 billion. The bonds are issued by EMCOR's sureties in return for a premium, which varies depending on the size and type of the bonds. The largest individual bond is approximately $170.0 million. EMCOR has agreed to indemnify the sureties for any payments made by them in respect of bonds issued on EMCOR's behalf.

EMCOR is subject to regulation with respect to the handling of certain materials used in construction which are classified as hazardous or toxic by Federal, State and local agencies. EMCOR's practice is to avoid participation in projects principally involving the remediation or removal of such materials. However, when remediation is a required part of its contract performance, EMCOR believes it complies with all applicable regulations governing the discharge of material into the environment or otherwise relating to the protection of the environment.

A subsidiary of EMCOR has guaranteed indebtedness of a venture in which it has a 40% interest; the other venture partner, Baltimore Gas and Electric, has a 60% interest. The venture designs, constructs, owns, operates, leases and maintains facilities to produce chilled water for sale to customers for use in air conditioning commercial properties. These guarantees are not expected to have a material adverse effect on EMCOR's financial position or results of operations. Each of the venturers is jointly and severally liable, in the event of default, for the venture's $25.0 million borrowing due December 2031. During September 2002, each venture partner contributed equity to the venture, of which EMCOR's contribution was $14.0 million.

In February 1995, as part of an investigation by the New York County District Attorney's office into the business affairs of a general contractor that did business with EMCOR's subsidiary, Forest Electric Corp. ("Forest"), a search warrant was executed at Forest's executive offices. On July 12, 2000, Forest was served with a Subpoena Duces Tecum to produce certain documents as part of a broader investigation by the New York County District Attorney's office into illegal business practices in the New York City construction industry. Forest has been informed by the New York County District Attorney's office that it and certain of its officers are targets of the investigation. Forest has produced documents in response to the subpoena and intends to cooperate fully with the District Attorney's office investigation as it proceeds.

In December 2001, the Company's Canadian subsidiary Comstock Canada Limited ("Comstock") commenced an action against Atomic Energy of Canada Limited ("AECL") in the Ontario Superior Court of Justice claiming approximately Cdn. $6.0 million (approximately $4.6 million) in connection with Comstock's work on two medical isotope nuclear reactors and associated works at AECL's facility at Chalk River, Ontario. Comstock's claim was for holdback, unpaid change requests, loss of productivity and extended duration costs. AECL filed an amended defense denying Comstock's claim and counterclaimed against Comstock for Cdn. $47.0 million (approximately $36.3 million) claiming fraud and substantial deficiencies in Comstock's performance of work which are alleged to have resulted in the need to replace much of Comstock's work and installed materials and the need to redesign and reinstall various components of the reactor systems. In December 2003, the matter was settled. The settlement provided for payment of a portion of Comstock's claim by AECL and did not require payment of any damages by Comstock.

On March 14, 2003, John Mowlem Construction plc ("Mowlem") presented a claim in arbitration against EMCOR's United Kingdom subsidiary, EMCOR Drake & Scull Group plc ("D&S"), in connection with a subcontract D&S entered into with Mowlem with respect to a project for the United Kingdom Ministry of Defence in Abbey Wood in Bristol, U.K. Mowlem seeks damages arising out of alleged defects in the D&S design and construction of the mechanical and electrical engineering services for the project. Mowlem's claim is for (pound)39.5 million (approximately $70.5 million), which includes costs allegedly incurred by Mowlem in connection with rectification of the alleged defects, overhead, legal fees, delay and disruption costs related to such defects, and interest on such amounts. The claim also includes amounts in respect of liabilities Mowlem accepted in connection with a settlement agreement it entered into with the Ministry of Defence and which it claims are attributable to D&S. D&S believes it has good and meritorious defenses to the Mowlem claim. D&S has denied liability and has asserted a counterclaim for approximately (pound)11.6 million (approximately $20.7 million) for certain design, labor and delay and disruption costs incurred by D&S in connection with its subcontract with Mowlem.

EMCOR is involved in other proceedings in which damages and claims have been asserted against it. EMCOR believes it has a number of valid defenses to such proceedings and claims and intends to vigorously defend itself and does not believe that a significant liability will result.

Inasmuch as the proceedings and claims in which EMCOR is involved range from a few thousand dollars to over $70.0 million, the outcome of which cannot be predicted, adverse results could have a material adverse effect on EMCOR's financial position and/or results of operations.

These consolidated financial statements and the schedule referred to below are the responsibility of the Company's management.

The schedule of Valuation and Qualifying Accounts is presented for purposes of complying with the Securities and Exchange Commission's rules and is not part of the basic financial statements.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

On May 15, 2002, EMCOR dismissed Arthur Andersen LLP ("Arthur Andersen") as its independent auditors and engaged Ernst & Young LLP ("Ernst & Young") to serve as its independent auditors for the fiscal year ended December 31, 2002. The Arthur Andersen dismissal and the Ernst & Young engagement were recommended by EMCOR's Audit Committee and approved by EMCOR's Board of Directors and became effective immediately.

Arthur Andersen's reports on EMCOR's consolidated financial statements as of and for the fiscal year ended December 31, 2001 did not contain an adverse opinion or disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope or accounting principles.

During the interim period from January 1, 2002 through May 15, 2002 and EMCOR's 2001 fiscal year, there were (i) no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to Arthur Andersen's satisfaction, would have caused Arthur Andersen to make a reference to the subject matter of the disagreements in connection with Arthur Andersen's reports on EMCOR's financial statements for such periods and (ii) no reportable events as defined in Item 304(a)(l)(v) of Regulation S-K.

EMCOR previously provided Arthur Andersen with a copy of the foregoing disclosures, and a letter from Arthur Andersen confirming its agreement with these disclosures was filed as an exhibit to EMCOR's Current Report on Form 8-K filed with the SEC on May 15, 2002 and which is hereby incorporated herein by reference.

During the interim period from January 1, 2002 through May 15, 2002 and EMCOR's 2001 fiscal year, EMCOR did not consult Ernst & Young with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on EMCOR's consolidated financial statements, or any other matters or reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.

ITEM 9A. CONTROLS AND PROCEDURES

Based on an evaluation as of December 31, 2003 of EMCOR's disclosure controls and procedures as required by Rule 13a-15(b) of the Securities Exchange Act of 1934, the Chairman of the Board and Chief Executive Officer of EMCOR, Frank T. MacInnis, and the Chief Financial Officer of EMCOR, Leicle E. Chesser, have concluded that EMCOR's disclosure controls and procedures (as defined in Rules 13a-15(e) of the Securities Exchange Act of 1934) are effective.

CODE OF ETHICS FOR CHIEF EXECUTIVE OFFICER AND SENIOR FINANCIAL OFFICERS

To ensure the continuing integrity of financial reporting and transactions, the Board of Directors of EMCOR Group, Inc. (the "Company") has adopted the following Code of Ethics, which applies to the chief executive officer (the "CEO") and the chief financial officer, the principal accounting officer, the treasurer and corporate controller of the Company and other senior financial officers performing similar functions who have been identified as such by the CEO (collectively, "Senior Financial Officers").

The Company's Code of Business Conduct and Ethics sets forth fundamental principles and key policies and procedures that govern the conduct of all Company directors, officers and employees, including the CEO and Senior Financial Officers. In addition, the CEO and Senior Financial Officers are also required to conduct their personal and professional affairs in a manner that is consistent with this Code of Ethics.

The CEO and all Senior Financial Officers must:

1. Engage in and promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

2. Take all reasonable measures to protect the confidentiality of non-public information about the Company and its subsidiaries and to prevent the unauthorized disclosure of such information unless required by applicable law, regulation or legal or regulatory process;

3. Produce full, fair, accurate, timely and understandable disclosure in reports and documents that the Company files with, or submits to, the U.S. Securities and Exchange Commission and in other public communications made by the Company and must bring to the attention of the Company's General Counsel and the Audit Committee of the Board of Directors of the Company (the "Audit Committee") any material information of which he or she may become aware that affects the disclosures made by the Company in its public filings;

4. Comply with governmental laws, rules and regulations applicable to the Company and its businesses;

5. Promptly bring to the attention of the General Counsel and the Audit Committee any information he or she may have concerning (i) significant or material deficiencies or weaknesses in the design or operation of the Company's internal controls which could have a material adverse effect on the Company's ability to record, process, summarize and report financial data and (ii) any fraud, whether or not material, involving any member of management or other employee who has a significant role in the Company's financial reporting, disclosures or internal controls; and

6. Promptly report any possible violation of this Code of Ethics to the General Counsel and the Audit Committee.

The CEO and the Senior Financial Officers shall facilitate the work of the Company's independent public auditors and shall not, directly or indirectly, take any action to fraudulently influence, coerce, manipulate or mislead the Company's independent public auditors for the purpose of rendering the Company's financial statements misleading.

The CEO and each Senior Financial Officer is accountable for his or her adherence to this Code of Ethics. The Board of Directors shall determine, or designate appropriate persons to determine, appropriate action to be taken in the event of any violation of this Code of Ethics. Such actions, which shall be reasonably designed to deter wrongdoing and to provide accountability for adherence to this Code of Ethics, may include disciplinary action, up to and including termination of employment.

Any waiver of a provision of this Code of Ethics, which may only be granted by the Board of Directors of the Company, shall be disclosed promptly as required by law.

If the CEO or any Senior Financial Officer has any questions regarding the best course of conduct in a particular situation, he or she should promptly contact the General Counsel of the Company at (203) 849-7831.

NOTICE REGARDING CONSENT OF ARTHUR ANDERSEN LLP

Section 11(a) of the Securities Act of 1933, as amended (the "Securities Act"), provides that if part of a registration statement at the time it becomes effective contains an untrue statement of a material fact, or omits a material fact required to be stated therein or necessary to make the statements therein not misleading, any person acquiring a security pursuant to such registration statement (unless it is proven that at the time of such acquisition such person knew of such untruth or omission) may assert a claim against, among others, every accountant who has consented to be named as having prepared or certified any part of the registration statement, or as having prepared or certified any report or valuation which is used in connection with the registration statement, with respect to the statement in such registration statement, report or valuation which purports to have been prepared or certified by the accountant.

The Annual Report on Form 10-K for the fiscal year ended December 31, 2003 (the "Form 10-K") to which this notice is filed as an exhibit is incorporated by reference into the following registration statements (collectively, the "Registration Statements") filed by EMCOR Group, Inc. with the Securities and Exchange Commission ("SEC"), and, for purposes of determining any liability under the Securities Act, is deemed to be a new registration statement for each Registration Statement into which it is incorporated by reference: Nos. 333-44369, 333-02819 and 333-75449.

On May 15, 2002, EMCOR dismissed Arthur Andersen LLP ("Arthur Andersen") to serve as its independent auditors and engaged Ernst & Young LLP ("Ernst & Young") to serve as its independent auditors for the fiscal year ending December 31, 2002. The Arthur Andersen dismissal and the Ernst & Young engagement were recommended by EMCOR's Audit Committee and approved by EMCOR's Board of Directors and became effective immediately. For additional information, see EMCOR's Current Report of Form 8-K filed with the SEC on May 15, 2002. EMCOR's understanding is that the staff of the SEC has taken the position that it will not accept consents from Arthur Andersen if the engagement partner for EMCOR's audit is no longer with Arthur Andersen. The engagement partner for EMCOR's audit is no longer with Arthur Andersen. As a result, EMCOR has been unable to obtain Arthur Andersen's written consent to the incorporation by reference into the Registration Statements of Arthur Andersen's audit report with respect to EMCOR's consolidated financial statements as of December 31, 2001 and December 31, 2000 and for the fiscal years then ended. Under these circumstances, Rule 437a under the Securities Act permits EMCOR to file this Form 10-K without a written consent from Arthur Andersen. As a result, however, Arthur Andersen will not have any liability under Section 11(a) of the Securities Act for any untrue statements of a material fact contained in the financial statements audited by Arthur Andersen or any omissions of a material fact required to be stated therein. Accordingly, you would be unable to assert a claim against Arthur Andersen under Section 11(a) of the Securities Act for any purchases of EMCOR's securities made on or after the date of this Form 10-K pursuant to the Registration Statements. To the extent provided in Section 11(b)(3)(C) of the Securities Act, however, other persons who are liable under Section 11(a) of the Securities Act, include EMCOR's officers and directors, may still rely on Arthur Andersen's original audit reports as being made by an expert of the purposes of establishing a due diligence defense under Section 11(b) of the Securities Act.
