NOTE C Valuation of Stock Option Grants

EMCOR has stock-based  compensation plans and programs. 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
Condensed Consolidated Statements of Operations for the three months ended March
31,  2004 and 2003 in respect of stock  options  granted  during  those  periods
inasmuch as EMCOR grants stock  options at fair market value.  Had  compensation
cost for these options been determined consistent with SFAS 123, "Accounting for
Stock-Based Compensation" and SFAS 148, "Accounting for Stock-Based Compensation
- -  Transition  and  Disclosure,"  EMCOR's net income,  basic  earnings per share
("Basic  EPS") and diluted  earnings per share  ("Diluted  EPS") would have been

NOTE D Segment Information

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 process
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) and, although this segment occasionally performs
construction  projects,  this  segment's  services are not generally  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).  The following  tables present  information  about industry
segments and geographic areas (in thousands):

NOTE E Retirement Plans - (continued)

Employer Contributions

As of March 31, 2004, EMCOR's United Kingdom subsidiary contributed $1.6 million
to its defined benefit  pension plan and anticipates  contributing an additional
$6.1 million in the remainder of 2004.

NOTE F Income Taxes

For the three  months  ended  March 31,  2004,  the income tax benefit was $12.4
million,  compared  to an income tax  provision  of $2.5  million  for the three
months  ended March 31, 2003.  The income tax benefit in the current  period was
comprised  of a  reversal  of $9.6  million  in income  tax  reserves  no longer
required based on a current analysis of probable exposures and $2.8 million of a
tax benefit at an effective income tax rate of 42% on a $6.7 million loss before
income  taxes.  The provision on income before income taxes for the three months
ended March 31, 2003 was at an effective income tax rate of approximately 44% on
$5.8 million of income before income taxes. The decrease in the effective income
tax rate for the three months ended March 31, 2004  compared to the three months
ended  March 31, 2003 was  primarily  due to  increased  income  anticipated  in
certain lower tax rate jurisdictions.

FINANCIAL CONDITION

Highlights


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 process
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) and, although this segment occasionally performs
construction  projects,  this  segment's  services are not generally  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).

Results of Operations

The results presented reflect certain reclassifications of prior period amounts
to conform to current year presentation.

As described below in more detail, revenues for the three months ended March 31,
2004  increased  4.5% to $1.11  billion  compared to $1.06 billion for the three
months ended March 31, 2003.  The revenues  increase was  principally  due to an
increase  in  work  performed  on  longer-term  transportation   infrastructure,
financial  services,  health  care and  hospitality  construction  projects  and
increases in site-based facilities services maintenance contracts. This increase
in revenues in the first  quarter of 2004  compared to the first quarter of 2003
was partially  offset by lower revenues from power generation  projects,  office
and manufacturing  construction projects,  mobile services,  discretionary small
projects, and repair and maintenance work.





Revenues  of United  States  electrical  construction  and  facilities  services
segment  for the three  months  ended  March 31, 2004  increased  $25.0  million
compared to the three months ended March 31, 2003. The revenues increase was due
to increased transportation  infrastructure,  financial services and hospitality
work,  partially offset by decreased power generation,  office and manufacturing
work.

Revenues  of United  States  mechanical  construction  and  facilities  services
segment  for the three  months  ended  March 31,  2004  increased  $6.2  million
compared to the three  months ended March 31,  2003.  The revenues  increase was
primarily  attributable to increased health care and hospitality work, partially
offset by decreased power generation work.

United States facilities services revenues,  which include those operations that
principally provide consulting and maintenance services, increased $10.1 million
for the three  months  ended March 31, 2004  compared to the three  months ended
March 31, 2003. The revenues  increase was primarily  attributable  to increased
revenues from site-based  facilities  services  contracts,  partially  offset by
decreased revenues from mobile services including  discretionary  small projects
and repair and  maintenance  work and the  completion  by  December  31, 2003 of
certain projects performed in the 2003 first quarter.

Revenues of Canada  construction  and  facilities  services  decreased  by $17.4
million for the three months  ended March 31, 2004  compared to the three months
ended March 31, 2003. This decrease in revenues for the three months ended March
31, 2004 was due to the  completion  by December  31, 2003 of certain  long-term
power generation projects.  The decrease was partially offset by $9.6 million of
increased  revenues  related to the change in the rate of exchange  for Canadian
dollars  to United  States  dollars  due to the  strengthening  of the  Canadian
dollar.

United Kingdom  construction and facilities  services  revenues  increased $24.2
million for the three months  ended March 31, 2004  compared to the three months
ended March 31, 2003 principally due to an increase of $19.6 million caused by a
change in the rate of exchange for British  pounds to United States  dollars due
to strengthening of the British pound.

Other  international  construction and facilities services activities consist of
EMCOR's  operations  primarily in the Middle East and South  Africa.  All of the
current  projects in these markets are being  performed by joint  ventures , and
accordingly,  the results of these joint  venture  operations  are accounted for
under the  equity  method of  accounting  because  EMCOR has less than  majority
ownership.  Therefore,  revenues  attributable  to such joint  ventures  are not
reflected as revenues in the consolidated financial statements.  EMCOR continues
to pursue new business  selectively in these markets and in Continental  Europe;
however, the availability of opportunities there has been significantly  reduced
as a result of local economic factors.

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 (in thousands, except for percentages):

                                            For the three months ended March 31,

Gross profit, as a percentage of revenues..          9.1%                 11.0%

Gross profit (revenues less cost of sales) decreased $15.6 million for the three
months  ended March 31, 2004  compared to the three months ended March 31, 2003.
Gross  profit as a  percentage  of revenues  was 9.1% for the three months ended
March 31, 2004 compared to 11.0% for the three months ended March 31, 2003. This
lower gross profit for the 2004 first quarter was primarily  attributable to: 1)
poor  contract  performance  on certain  construction  work related to increased
labor  requirements to perform the work and continued reduced labor productivity
due  to  the  uncertain   construction  job  market;   2)  continued   decreased
availability  of generally  more  profitable  discretionary  small  projects and
repair  and  maintenance  work;  3)  increased  competition  for,  and a related
decrease in gross profit margin on, commercial and industrial work in the United
States;  and 4) an increase in the  percentage of work relating to public sector
construction  work that  typically  has lower gross profit  margins than private
sector work. These factors were partially offset by improvements in gross profit
from certain United States construction work and site-based  facilities services
contracts  and by  reduced  losses  from the  United  Kingdom  construction  and
facilities services segment.


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

                                                                             ------------------------------------

Selling, general and administrative expenses, as a percentage of revenues..             9.1%           10.3%


Selling,  general and  administrative  expenses for the three months ended March
31, 2004 decreased $8.2 million to $101.0 million compared to $109.2 million for
the three  months  ended March 31,  2003.  Selling,  general and  administrative
expenses as a percentage  of revenues were 9.1% for the three months ended March
31, 2004,  compared to 10.3% for the three months ended March 31, 2003.  For the
three month period ended March 31,  2004,  the decrease in selling,  general and
administrative expenses both in dollars and as a percentage of revenues compared
to the same  period in the prior  year was  primarily  attributable  to  reduced
incentive  compensation  related  to less  favorable  financial  performance,  a
reduction in personnel and reduced provisions for doubtful accounts.

Restructuring expenses

Restructuring  expenses,  primarily relating to employee severance  obligations,
were $5.2 million for the three months ended March 31, 2004.  Approximately $3.0
million of the  restructuring  obligations were paid as of March 31, 2004. EMCOR
anticipates paying  approximately  $1.7 million of the remaining  obligations in
fiscal 2004 and $0.5 million,  thereafter.  There were no restructuring expenses
for the three months ended March 31, 2003.

As described below in more detail,  operating  income decreased by $12.6 million
for the three months ended March 31, 2004 to a loss of $5.0 million  compared to
operating income of $7.6 million for the three months ended March 31, 2003.

United States electrical  construction and facilities  services operating income
for the three months ended March 31, 2004 increased $4.3 million compared to the
three  months  ended  March 31,  2003.  The  increase  in  operating  income was
primarily   the  result  of  1)  increased   gross   profit  on   transportation
infrastructure, financial services, and hospitality construction projects and 2)
increased  estimated  cost  recoveries  upon  completion  of  certain  projects,
partially  offset  by  a  decline  in  office  and  manufacturing  work  and  by
unprofitable performance on certain power generation projects.  Selling, general
and administrative  expenses decreased primarily due to a reduction in personnel
and reduced provisions for doubtful accounts.

United States mechanical construction and facilities services operating loss for
the three months ended March 31, 2004 was $7.8 million, a $12.1 million decrease
compared to  operating  income of $4.3  million the three months ended March 31,
2003.  The  operating  loss was  primarily  attributable  to:  1) poor  contract
performance on certain construction work related to increased labor requirements
to  perform  the  work  and  continued  reduced  labor  productivity  due to the
uncertain  construction  job market;  2) a continued  decreased  availability of
generally  more   profitable   discretionary   small  projects  and  repair  and
maintenance work; and 3) reductions in estimated cost recoveries upon completion
of certain  projects.  Partially  offsetting the losses were decreased  selling,
general and administrative expenses related to reduced incentive compensation on
less favorable financial performance and personnel reductions.

United  States  facilities  services  operating  loss for the three months ended
March 31, 2004 was $1.6 million compared to operating income of $2.2 million for
the three months ended March 31, 2003.  The operating loss was  attributable  to
approximately $2.3 million of losses on certain construction  projects,  outside
of the  normal  facilities  services  operations  of  this  segment,  that  were
contracted  for by  subsidiaries  in this segment prior to their  acquisition by
EMCOR. In addition to these losses, in the first quarter of 2004 compared to the
first  quarter  of  2003,   there  was  a  decrease  in  mobile  services  work,
discretionary  small  projects  and  repair  and  maintenance  work.  Also,  the
completion of certain projects  performed during the period ended March 31, 2003
contributed  to the decrease.  Conversely,  there was an increase in income from
site-based facilities services in the 2004 first quarter compared to the similar
2003 period. The losses were also partially offset by decreased selling, general
and  administrative  expenses related to reduced incentive  compensation on less
favorable financial  performance,  reduction in personnel and reduced provisions
for doubtful accounts.

Canada  construction and facilities  services operating income was $0.02 million
for the three  months  ended March 31,  2004,  compared to $0.6  million for the
three  months  ended  March 31,  2003.  The  decrease  in  operating  income was
attributable  to an  increase in selling,  general and  administrative  expenses
related to increased travel and other direct selling expenses.

United Kingdom  construction  and facilities  services  operating losses for the
three months  ended March 31, 2004 and 2003 were $1.3 million and $4.5  million,
respectively.  This decrease in operating losses was attributable to a reduction
in selling,  general and administrative  expenses related to a reorganization of
the United  Kingdom  operations  in late 2003 and an  improvement  in 2004 first
quarter gross profit inasmuch as there had been unfavorable  project  close-outs
in the first  quarter of 2003.  The change in the rate of  exchange  for British
pounds to United  States  dollars  due to  strengthening  of the  British  pound
resulted in a $0.2 million incremental loss in the 2004 first quarter.

Other  international  construction and facilities  services operating income was
$0.3 million for the three months ended March 31, 2004  compared to $0.2 million
for the three  months  ended  March 31,  2003.  EMCOR  continues  to pursue  new
business  selectively  in the  Middle  East  and  South  Africa  as  well  as in
Continental  Europe;   however,  the  availability  of  opportunities  has  been
significantly reduced as a result of local economic factors.

Corporate  administration  expense for the three months ended March 31, 2004 was
$6.7 million compared to $8.2 million for the three months ended March 31, 2003.
The decrease in expenses was primarily due to general cost reductions.


Restructuring  expenses,  primarily relating to employee severance  obligations,
were $5.2  million  for the three  months  ended March 31,  2004.  There were no
restructuring expenses for the three months ended March 31, 2003.

Interest  expense  for the three  months  ended March 31, 2004 and 2003 was $1.8
million and $2.0  million,  respectively.  The decrease in interest  expense was
primarily  due to reduced  borrowings  under the working  capital  credit  line.
Interest  income of $0.2  million  remained  constant for the three months ended
March  31,  2004  compared  to the same  three  months in 2003.  Changes  in the
interest  rate on  borrowings  did not have a  significant  impact  on  interest
expense or income during the first quarter of 2004.

For the three  months  ended  March 31,  2004,  the income tax benefit was $12.4
million,  compared  to an income tax  provision  of $2.5  million  for the three
months  ended March 31, 2003.  The income tax benefit in the current  period was
comprised  of a  reversal  of $9.6  million  in income  tax  reserves  no longer
required based on a current analysis of probable exposures and $2.8 million of a
tax benefit at an effective income tax rate of 42% on a $6.7 million loss before
income  taxes.  The provision on income before income taxes for the three months
ended March 31, 2003 was at an effective income tax rate of approximately 44% on
$5.8 million of income before income taxes. The decrease in the effective income
tax rate for the three months ended March 31, 2004  compared to the three months
ended  March 31, 2003 was  primarily  due to  increased  income  anticipated  in
certain lower tax rate jurisdictions.

EMCOR's  contract  backlog at March 31, 2004 was $3.08 billion compared to $3.09
billion of contract  backlog at March 31, 2003.  The $0.01 billion  decrease was
primarily  due  to  a  $0.18  million  decrease  in  United  States   electrical
construction and facilities  services segment backlog,  mostly offset by a $0.15
billion  increase in United  States  facilities  backlog and minor  increases in
EMCOR's other segments.

EMCOR's  contract  backlog was $3.08 billion at March 31, 2004 and $3.03 billion
at December 31, 2003.  The $0.05  billion  increase was primarily due to a $0.15
billion increase in backlog for the United States  facilities  services segment,
partially offset by decreases in backlog for EMCOR's other segments.

Liquidity and Capital Resources

The following  table  presents  EMCOR's net cash (used in) provided by operating
activities, investing activities and financing activities (in thousands):

                                                            For the three months
                                                               ended March 31,

Net cash (used in) provided by financing activities...    $(20,723)    $ 33,272

EMCOR's  consolidated cash balance decreased by approximately $25.3 million from
$78.3 million at December 31, 2003 to $53.0 million at March 31, 2004. The $58.9
million  improvement  in net cash  used in  operating  activities  for the three
months  ended March 31, 2004  compared to the three  months ended March 31, 2003
was  primarily  due to greater  cash  required  in the first  quarter of 2003 to
support the shift toward  increased  public  sector work,  which work  typically
involves  larger projects and significant  working  capital  requirements  until
initial  billing  milestones  can be reached.  In addition,  in the 2004 period,
there was an  improvement  in EMCOR's  net  over-billed  position,  which is 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,  contributing to the reduction in cash used in operating
activities.  Net cash used in investing  activities of $2.1 million in the first
quarter of 2004  decreased  $7.1  million  compared to $9.2  million in the same
quarter in the prior  year  primarily  due to a $2.9  million  reduction  in the
purchase of property,  plant and equipment,  a $1.7 million increase in proceeds
on  investments  and a $1.7 million  reduction in earn-out  payments as earn-out
periods provided for in most acquisition  agreements have expired. Net cash used
in financing  activities of $20.7 million in the first quarter of 2004 decreased
$54.0  million  from the net cash  provided  by  financing  activities  of $33.3
million  for the  first  quarter  of 2003  and  primarily  was  attributable  to
repayments under the working capital credit line.

(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,  classified as other
     long-term liabilities in EMCOR's consolidated balance sheets. Cash payments
     for insurance related liabilities may be payable beyond three years, but it
     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.

EMCOR's revolving credit agreement (the "Revolving  Credit  Facility")  provides
for a credit facility of $350.0  million.  As of March 31, 2004 and December 31,
2003,  EMCOR had  approximately  $52.0  million and $42.9  million of letters of
credit  outstanding,  respectively,  under the Revolving  Credit  Facility.  The
amounts  borrowed under the Revolving  Credit  Facility as of March 31, 2004 and
December 31, 2003 were $118.4 million and $139.4 million, respectively.

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.

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  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 backlog
increases.  As of March 31,  2004,  sureties had issued bonds for the account of
EMCOR in the  aggregate  amount of  approximately  $1.8  billion.  The bonds are
issued by EMCOR's  sureties in return for a premium,  which varies  depending on
the size and type of bond. 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 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 typically  been, and is generally
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 flows than
the construction  market.  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  discretionary  small
projects from the private sector and companies  such as EMCOR more  aggressively
bid large long-term  infrastructure and public sector contracts.  Performance of
long duration contracts typically requires 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  $139.6  million  and $95.8  million  as of March  31,  2004 and
December 31, 2003, respectively.

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
demand cycles in 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 March 31, 2004 and December 31, 2003,  EMCOR was  utilizing  approximately
$41.4 million and $37.7  million,  respectively,  of letters of credit  obtained
under its revolving credit facility as collateral for its insurance obligations.

Application of Critical Accounting Policies

The condensed  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 the annual  report on
Form 10-K for the year ended December 31, 2003. There was no initial adoption of
any  accounting  policies  during the three months  ended March 31, 2004.  EMCOR
believes that some of the more critical  judgment  areas in the  application  of
accounting   policies  that  affect  its  financial  condition  and  results  of
operations  are 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 for 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
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 in dispute 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 (claims and
unapproved change orders). 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.  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 service  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  provision for bad debts during the three months
ended March 31, 2004 and 2003 were $0.5 and $3.0 million, respectively. At March
31, 2004 and December  31, 2003,  accounts  receivable  of $1,044.0  million and
$1,009.2 million,  respectively,  included allowances of $43.6 million and $43.7
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 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 March 31, 2004 and December 31,
2003, the total valuation allowance on net deferred tax assets was approximately
$2.0 million.

Intangible Assets

As of March 31, 2004, EMCOR had goodwill and net identifiable  intangible assets
(primarily  the  market  value  of  its  backlog,   customer  relationships  and
trademarks and trade names) of $279.3  million and $21.4 million,  respectively,
in connection with the acquisition of certain  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 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 March 31, 2004,  no indicators of impairment of its goodwill or
identifiable intangible assets existed in accordance with the provisions of SFAS
142.

associated with foreign operations.  Certain of the risks and factors associated
with EMCOR's  business are also discussed in EMCOR's 2003 Form 10-K and in other
reports  filed  by it  from  time to  time  with  the  Securities  and  Exchange
Commission.  Readers  should  take the  aforementioned  risks and  factors  into
account in evaluating any forward-looking statements.

ITEM 3 QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

EMCOR has not used derivative  financial  instruments for any purpose during the
three months ended March 31, 2004 and 2003,  including trading or speculation 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 March 31,
2004, there was $118.4 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 March 31,
2004)  plus 0% to 1.0%  based on certain  financial  tests or (2) United  States
dollar  LIBOR (at March 31,  2004 the rate was 1.09%) plus 1.5% to 2.5% based on
certain  financial  tests.  The interest  rates in effect at March 31, 2004 were
4.25% and 2.84% for the prime  commercial  lending  rate and the  United  States
dollar  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. Based on the borrowings  outstanding of $118.4 million,  if the
overall interest rates were to increase by 1.0%, the net of tax interest expense
would increase approximately $0.7 million in the next twelve months. Conversely,
if the overall  interest rates were to decrease by 1.0%,  interest expense would
decrease by approximately  $0.7 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 its  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 settle these obligations is negatively impacted by economic conditions. EMCOR
continually  monitors  the  creditworthiness  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 the  end of the  period.  The  resulting
translation  adjustments are recorded as accumulated other comprehensive  income
(loss),  a component of  stockholders'  equity,  in the  condensed  consolidated
balance  sheets.  EMCOR  believes the  exposure to the effects that  fluctuating
foreign currencies may have on the 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.

In  addition,  EMCOR is  exposed  to  market  risk of  fluctuations  in  certain
commodity  prices of  materials  such as copper and steel  utilized  in both its
construction  and  facilities  services  operations.  EMCOR  believes  it can be
successful in recovery of commodity price escalations.

ITEM 4 CONTROLS AND PROCEDURES

(a)  Based on an  evaluation  of  EMCOR's  disclosure  controls  and  procedures
     conducted within 90 days of the date of filing this Form 10-Q, 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-14(c) and 15d-14(c))  promulgated under the Securities  Exchange Act of
     1934 are effective.

(b)  There were no  significant  changes in the  internal  controls  or in other
     factors that could  significantly  affect these controls  subsequent to the
     date of their most recent evaluation.





PART II - OTHER INFORMATION

ITEM 1  LEGAL PROCEEDINGS

Except  for the  legal  proceedings  described  below,  there  have  been no new
developments during the quarter ended March 31, 2004 regarding legal proceedings
reported in EMCOR's  Annual Report on Form 10-K for the year ended  December 31,
2003.

EMCOR and three of its officers (Chairman of the Board, Chief Executive Officer,
and President  Frank T. MacInnis,  Executive Vice President and Chief  Financial
Officer Leicle E. Chesser, and Senior Vice  President-Chief  Accounting Officer,
and Treasurer  Mark Pompa) have been named as defendants in two purported  class
actions filed in the United States  District Court of Connecticut - one entitled
Simons v. EMCOR Group, Inc., Leicle E. Chesser, Frank T. MacInnis and Mark Pompa
filed on March 31, 2004 and the other  entitled V. Richard Bolan v. EMCOR Group,
Inc.,  Leicle E. Chesser,  Frank T. MacInnis and Mark A. Pompa filed on April 8,
2004. Plaintiffs, alleged purchasers of shares of common stock of EMCOR, purport
to represent a class composed of all persons who purchased or otherwise acquired
EMCOR common stock and/or other securities  between April 9, 2003 and October 2,
2003  inclusive.  The  complaints  allege  violations  of  Section  10(b) of the
Securities  Exchange Act and Rule 10b-5  thereunder  and of Section 20(A) of the
Securities  Exchange  Act,  relating to alleged  misstatements  and omissions in
certain of the Company's  filings with the Securities  and Exchange  Commission,
press releases and other public statements  between April 9 and October 2, 2003,
and seek damages on behalf of the purported class in unspecified amounts.  EMCOR
and the individual defendants believe the plaintiffs'  allegations to be without
merit and intend to vigorously defend against them.

In July 2003, EMCOR's subsidiary, the Poole & Kent Corporation ("Poole & Kent"),
was served with a subpoena  duces tecum by a grand jury  empaneled by the United
States District Court for the District of Maryland which is investigating, among
other  things,   Poole  &  Kent's  use  of  minority  and  woman-owned  business
enterprises. Poole & Kent has produced documents in response to the subpoena and
to subsequent  subpoenae directed to it requesting certain business records.  On
April 26,  2004,  Poole & Kent was advised that it is a target of the grand jury
investigation. Poole & Kent is cooperating with the investigation.

ITEM 5 OTHER INFORMATION

The Nominating and Corporate  Governance  Committee (the  "Corporate  Governance
Committee") of the Board of Directors of EMCOR will consider recommendations for
candidates  for Board  membership  suggested by Committee  members,  other Board
members and  stockholders.  A stockholder  who wishes the  Corporate  Governance
Committee to consider his/her  recommendations  for nominees for the position of
director  should  submit  his/her  recommendations  in writing to the  Corporate
Governance  Committee in care of Corporate  Secretary,  EMCOR Group,  Inc.,  301
Merritt Seven,  Norwalk,  Connecticut 06851,  together with whatever  supporting
material the  stockholder  considers  appropriate.  The material,  at a minimum,
should  include such  background  and  biographical  material as will enable the
Corporate  Governance  Committee to make an initial  determination as to whether
the  prospective  nominee  satisfies  the criteria for  directors set out in the
Company's Corporate Governance  Guidelines.  The Corporate Governance Guidelines
are available at the Company's website at www.emcorgroup.com.

If the  Corporate  Governance  Committee  identifies a need to replace a current
member of the Board of Directors,  to fill a vacancy in the Board,  or to expand
the size of the Board,  the process to be followed by the  Committee to identify
and  evaluate  candidates  includes:  (a)  consideration  of  those  individuals
recommended  by  stockholders  as  candidates  for  Board  membership  and those
individuals  recommended  in response to requests  for  recommendations  made of
Board members and others,  including  those  suggested by third party  executive
search firms  retained by the  Committee,  from time to time,  (b) meetings from
time  to time to  evaluate  biographical  information  and  background  material
relating to candidates,  and (c) interviews of selected candidates by members of
the Committee.

As provided in the Company's Corporate Governance Guidelines,  in its assessment
of each potential  candidate,  the Corporate Governance Committee is to consider
