General



The following discussion and analysis of the financial condition and results of
operations of Quanta Services, Inc. (together with its subsidiaries, Quanta, we,
us or our) should be read in conjunction with our consolidated financial
statements and related notes in Item 8. Financial Statements and Supplementary
Data of this Annual Report. The discussion below contains forward-looking
statements that are based upon our current expectations and are subject to
uncertainty and changes in circumstances. Actual results may differ materially
from these expectations due to inaccurate assumptions and known or unknown risks
and uncertainties, including those identified in Cautionary Statement About
Forward-Looking Statements and Information above and in Item 1A. Risk Factors of
this Annual Report.

The discussion summarizing the significant factors which affected the results of
operations and financial condition for the year ended December 31, 2021,
including the changes in results of operations between the years ended December
31, 2021 and 2020, can be found in Part II, Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations of our Annual Report
on Form 10-K for the year ended December 31, 2021, which was filed with the SEC
on February 25, 2022.

Overview

Overall, our 2022 results reflect increased demand for our services, as revenue and operating income increased in all our segments as compared to 2021.



With respect to our Electric Power Infrastructure Services segment, utilities
are continuing to invest significant capital in their electric power delivery
systems through multi-year grid modernization and reliability programs, as well
as with respect to system upgrades and hardening programs in response to
recurring severe weather events. We have also experienced high demand for new
and expanded transmission, substation and distribution infrastructure needed to
reliably transport power.

With respect to our Renewable Energy Infrastructure Solutions segment, the
transition to a reduced-carbon economy is continuing to drive demand for
renewable generation and related infrastructure (e.g., high-voltage electric
transmission and substation infrastructure), as well as interconnection services
necessary to connect and transmit renewable-generated electricity to existing
electric power delivery systems. Our acquisition of Blattner in the fourth
quarter of 2021 had a significant incremental impact on our ability to perform
these services during 2022. Despite these positive longer-term trends, certain
of our customers experienced supply chain challenges during 2022 that resulted
in delays and shortages of, and increased costs for, materials necessary for
certain projects, particularly sourcing restrictions related to solar panels
necessary for the utility scale solar industry.

With respect to our Underground Utility and Infrastructure Solutions segment, in
2022 we continued to experience strong demand for our services focused on
utility spending, in particular our gas distribution services to natural gas
utilities that are implementing modernization programs, and our downstream
industrial services, as these customers continued to move forward with certain
maintenance and capital spending that was deferred during the course of the
COVID-19 pandemic. Our revenues with respect to larger pipeline services have
also fluctuated in recent years, and we had a significant increase in larger
pipeline projects in Canada in 2022 as compared to 2021.

Increased revenues and operating income across all our segments during 2022 generated $1.1 billion of cash provided by operating activities, a 94.1% increase relative to 2021, which allowed us to execute our business plan, repurchase $128 million of common stock and pay $41 million of dividends. Available commitments under our senior credit facility and cash and cash equivalents as of December 31, 2022 was $2.4 billion.



We expect the strong demand for our services will continue. Our remaining
performance obligations and backlog as of December 31, 2022 of $8.8 billion and
$24.1 billion increased 49.3%, and 25.0%, respectively, relative to 2021. For a
reconciliation of backlog to remaining performance obligations, the most
comparable financial measure prepared in conformity with generally accepted
accounting principles in the United States (GAAP), see Non-GAAP Financial
Measures below.

Significant Factors Impacting Results



Our revenues, profit, margins and other results of operations can be influenced
by a variety of factors in any given period, including those described in Item
1. Business and Item 1A. Risk Factors of this Annual Report, and those factors
have caused fluctuations in our results in the past and are expected to cause
fluctuations in our results in the future. Additional information with respect
to certain of those factors is provided below.
                                       42
--------------------------------------------------------------------------------

Seasonality. Typically, our revenues are lowest in the first quarter of the year
because cold, snowy or wet conditions can create challenging working
environments that are more costly for our customers or cause delays on projects.
In addition, infrastructure projects often do not begin in a meaningful way
until our customers finalize their capital budgets, which typically occurs
during the first quarter. Second quarter revenues are typically higher than
those in the first quarter, as some projects begin, but continued cold and wet
weather can often impact productivity. Third quarter revenues are typically the
highest of the year, as a greater number of projects are underway and operating
conditions, including weather, are normally more accommodating. Generally,
revenues during the fourth quarter are lower than the third quarter but higher
than the second quarter, as many projects are completed and customers often seek
to spend their capital budgets before year end. However, the holiday season and
inclement weather can sometimes cause delays during the fourth quarter, reducing
revenues and increasing costs. These seasonal impacts are typical for our U.S.
operations, but seasonality for our international operations may differ. For
example, revenues for certain projects in Canada are typically higher in the
first quarter because projects are often accelerated in order to complete work
while the ground is frozen and prior to the break up, or seasonal thaw, as
productivity is adversely affected by wet ground conditions during warmer
months.

Weather, natural disasters and emergencies. The results of our business in a
given period can be impacted by adverse weather conditions, severe weather
events, natural disasters or other emergencies, which include, among other
things, heavy or prolonged snowfall or rainfall, hurricanes, tropical storms,
tornadoes, floods, blizzards, extreme temperatures, wildfires, post-wildfire
floods and debris flows, pandemics and earthquakes. These conditions and events
can negatively impact our financial results due to, among other things, the
termination, deferral or delay of projects, reduced productivity and exposure to
significant liabilities. However, severe weather events can also increase our
emergency restoration services, which typically yield higher margins due in part
to higher equipment utilization and absorption of fixed costs.

Demand for services. We perform the majority of our services under existing
contracts, including MSAs and similar agreements pursuant to which our customers
are not committed to specific volumes of our services. Therefore our volume of
business can be positively or negatively affected by fluctuations in the amount
of work our customers assign us in a given period, which may vary by geographic
region. Examples of items that may cause demand for our services to fluctuate
materially from quarter to quarter include: the financial condition of our
customers, their capital spending and their access to capital; acceleration of
any projects or programs by customers (e.g., modernization or hardening
programs); economic and political conditions on a regional, national or global
scale, including availability of renewable energy tax credits; interest rates;
governmental regulations affecting the sourcing and costs of materials and
equipment; other changes in U.S. and global trade relationships; and project
deferrals and cancellations.

Revenue mix and impact on margins. The mix of revenues based on the types of
services we provide in a given period will impact margins, as certain industries
and services provide higher-margin opportunities. Our larger or more complex
projects typically include, among others, transmission projects with higher
voltage capacities; pipeline projects with larger-diameter throughput
capacities; large-scale renewable generation projects; and projects with
increased engineering, design or construction complexities, more difficult
terrain or geographical requirements, or longer distance requirements. These
projects typically yield opportunities for higher margins than our recurring
services under MSAs described above, as we assume a greater degree of
performance risk and there is greater utilization of our resources for longer
construction timeframes. However, larger projects are subject to additional risk
of regulatory delay and cyclicality. Project schedules also fluctuate,
particularly in connection with larger, more complex or longer-term projects,
which can affect the amount of work performed in a given period. Furthermore,
smaller or less complex projects typically have a greater number of companies
competing for them, and competitors at times may more aggressively pursue
available work. A greater percentage of smaller scale or less complex work also
could negatively impact margins due to the inefficiency of transitioning between
a greater number of smaller projects versus continuous production on fewer
larger projects. As a result, at times we may choose to maintain a portion of
our workforce and equipment in an underutilized capacity to ensure we are
strategically positioned to deliver on larger projects when they move forward.

Project variability and performance. Margins for a single project may fluctuate
period to period due to changes in the volume or type of work performed, the
pricing structure under the project contract or job productivity. Additionally,
our productivity and performance on a project can vary period to period based on
a number of factors, including unexpected project difficulties or site
conditions (including in connection with difficult geographic characteristics);
project location, including locations with challenging operating conditions;
whether the work is on an open or encumbered right of way; inclement weather or
severe weather events; environmental restrictions or regulatory delays;
protests, other political activity or legal challenges related to a project; the
performance of third parties; and the impact of the COVID-19 pandemic. Moreover,
we currently generate a significant portion of our revenues under fixed price
contracts, and fixed price contracts are more common in connection with our
larger and more complex projects that typically involve greater performance
risk. Under these contracts, we assume risks related to project estimates and
execution, and project revenues can vary, sometimes substantially, from our
original projections due to a variety of factors, including the additional
complexity, timing uncertainty or extended bidding, regulatory and permitting
processes associated with these projects. These variations can result in a
reduction in expected profit,
                                       43
--------------------------------------------------------------------------------

the incurrence of losses on a project or the issuance of change orders and/or assertion of contract claims against customers. See Revenue Recognition - Contract Estimates and Changes in Estimates in Note 4 of the Notes to Consolidated Financial Statements in Item 8. Financial Statements and Supplementary Data in Part II of the 2022 Annual Report.



Subcontract work and provision of materials. Work that is subcontracted to other
service providers generally yields lower margins, and therefore an increase in
subcontract work in a given period can decrease operating margins. In recent
years, we have subcontracted approximately 20% of our work to other service
providers. Our customers are usually responsible for supplying the materials for
their projects. However, under some contracts, including contracts for projects
where we provide EPC services, we agree to procure all or part of the required
materials. Margins may be lower on projects where we furnish a significant
amount of materials, as our markup on materials is generally lower than our
markup on labor costs, and in a given period an increase in the percentage of
work with greater materials procurement requirements may decrease our overall
margins, including in some cases our assuming price risk. Furthermore, as
described further in Item 1. Business, fluctuations in the price or availability
of materials, equipment and consumables that we or our customers utilize could
impact costs to complete projects.

                                       44
--------------------------------------------------------------------------------

Revenues. Revenues increased due to a $1.95 billion increase in revenues from
our Renewable Energy Infrastructure Solutions segment, a $1.32 billion increase
in revenues from our Electric Power Infrastructure Solutions segment, and a
$824.4 million increase in revenues from our Underground Utility and
Infrastructure Solutions segment. See Segment Results below for additional
information and discussion related to segment revenues.

Cost of services. Costs of services primarily includes wages, benefits, subcontractor costs, materials, equipment, and other direct and indirect costs, including related depreciation. The increase in cost of services generally correlates to the increase in revenues.

Equity in earnings of integral unconsolidated affiliates. The increase was primarily driven by our LUMA joint venture. For additional information, see Note 8 of the Notes to Consolidated Financial Statements in Item 8. Financial Statements and Supplementary Data of this Annual Report.



Selling, general and administrative expenses. The increase was primarily
attributable to a $149.7 million increase in expenses associated with acquired
businesses. Also contributing to the increase were the following items to
support business growth: a $32.8 million increase in compensation expense,
primarily associated with increased salaries and non-cash stock compensation
expense; a $25.2 million increase in travel and related expenses; and a $7.7
million increase in rent and information technology expenses. Partially
offsetting these increases was a $23.6 million decrease in expense related to
deferred compensation liabilities. The fair market value changes in deferred
compensation liabilities were largely offset by changes in the fair value of
corporate-owned life insurance (COLI) assets associated with the deferred
compensation plan, which are included in "Other (expense) income, net" as
discussed below. Also partially offsetting these increases was a specific
provision for credit loss of $31.7 million recorded in 2021.

Amortization of intangible assets. The increase was primarily related to $196.3
million of incremental amortization of intangible assets associated with
recently acquired businesses, driven by the acquisition of Blattner, partially
offset by reduced amortization expense associated with older acquired intangible
assets, as certain of these assets became fully amortized.

Asset impairment charges. The increase was primarily due to $11.7 million of
asset impairment charges related to a software implementation project at an
acquired company, which commenced prior to our acquisition and was discontinued
in the fourth quarter of 2022.

Change in fair value of contingent consideration liabilities. Contingent
consideration liabilities are payable in the event prescribed performance
objectives are achieved by certain acquired businesses during designated
post-acquisition periods. Future changes in fair value are expected to be
recorded periodically until the contingent consideration liabilities are
settled. For additional information regarding these liabilities, see Note 6 of
the Notes to Consolidated Financial Statements in Item 8. Financial Statements
and Supplementary Data of this Annual Report.

Operating income. Operating income for the Electric Power Infrastructure
Solutions, Renewable Energy Infrastructure Solutions and Underground Utility and
Infrastructure Solutions segments increased $93.4 million, $122.4 million and
$167.4 million, respectively. These increases were partially offset by an
increase in Corporate and Non-Allocated Costs of $174.6 million, which includes
amortization expense. Results for each of our business segments and Corporate
and Non-Allocated Costs are discussed in the Segment Results section below.

EBITDA and adjusted EBITDA. EBITDA increased 31.5%, or $350.9 million, to $1.46
billion as compared to $1.11 billion for the year ended December 31, 2021, and
adjusted EBITDA increased 33.8%, or $425.8 million, to $1.68 billion as compared
to $1.26 billion for the year ended December 31, 2021. For a reconciliation of
EBITDA and adjusted EBITDA to net income attributable to common stock, the most
comparable GAAP financial measure, see Non-GAAP Financial Measures below.

Interest and other financing expenses. Approximately two-thirds of the increase
resulted from higher debt outstanding during 2022 as compared to 2021. Our
long-term debt increased significantly at the end of 2021 in connection with our
acquisition of Blattner. The remaining increase was primarily driven by higher
interest rates impacting our variable rate debt.

Interest income. Interest income decreased during the year ended December 31,
2022 primarily due to interest received during the year ended December 31, 2021
related to a settlement with a customer.

Other (expense) income, net. The net other expense for the year ended
December 31, 2022 was primarily the result of an unrealized loss of $91.5
million resulting from the remeasurement of the fair value of our investment in
a publicly traded broadband technology provider, Starry Group Holdings, Inc.
(Starry), based on the market price of Starry's common stock as of December 31,
2022. Also included in other (expense) income, net was a $13.8 million
mark-to-market loss in 2022 compared to a $8.6 million mark-to-market gain in
2021 associated with our deferred compensation plan. This amount was largely
offset by corresponding changes in the fair market value of the liabilities
associated with our deferred compensation plan, which are recorded in selling,
general, and administrative expenses, as discussed above. Partially offsetting
these increases in expenses
                                       45
--------------------------------------------------------------------------------

were a $25.9 million gain on the sale of an investment in a non-integral unconsolidated affiliate recognized in the fourth quarter of 2022, of which $10.4 million was attributable to a non-controlling interest as noted below, and an $18.2 million increase in equity in earnings of non-integral affiliates.



Provision for income taxes. The effective tax rates for the years ended
December 31, 2022 and 2021 were 27.3% and 21.0%. The higher effective tax rate
is primarily attributable to the recognition of a $22.7 million valuation
allowance resulting from the unrealized loss on our investment in Starry
described above, and a year over year increase in tax expense of $9.9 million
driven by mark-to-market accounting on corporate-owned life insurance products
associated with our deferred compensation plan. If the Starry losses become
realized for tax purposes, we could release a portion of the valuation allowance
by the amount Starry losses offset certain capital gains. For additional
information regarding our provision for income taxes, see Note 12 of the Notes
to Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report.

Net income attributable to non-controlling interests. The increase in net income
attributable to non-controlling interests is primarily related to the $10.4
million gain on sale of the investment in a non-integral equity unconsolidated
affiliate. See Note 8 of the Notes to Consolidated Financial Statements in
Item 8. Financial Statements and Supplementary Data of this Annual Report.

Comprehensive income. See Statements of Comprehensive Income in Item 8.
Financial Statements and Supplementary Data of this Annual Report. Comprehensive
income decreased by $63.1 million in 2022 as compared to 2021, primarily due to
higher foreign currency translation adjustments losses and the aforementioned
increase in net income attributable to non-controlling interests, partly offset
by higher net income. The predominant functional currencies for our operations
outside the U.S. are Canadian and Australian dollars. The $66.8 million increase
in foreign currency translation loss in the year ended December 31, 2022
primarily resulted from the strengthening of the U.S. dollar against both the
Canadian and Australian dollars as of December 31, 2022 when compared to
December 31, 2021.

Segment Results



We report our results under three reportable segments: Electric Power
Infrastructure Solutions, Renewable Energy Infrastructure Solutions and
Underground Utility and Infrastructure Solutions. Reportable segment
information, including revenues and operating income by type of work, is
gathered from each of our operating companies. Classification of our operating
company revenues by type of work for segment reporting purposes can at times
require judgment on the part of management. Our operating companies may perform
joint projects for customers in multiple industries, deliver multiple types of
services under a single customer contract or provide service offerings to
various industries. For example, we perform joint trenching projects to install
distribution lines for electric power and natural gas customers. Integrated
operations and common administrative support for operating companies require
that certain allocations be made to determine segment profitability, including
allocations of corporate shared and indirect operating costs, as well as general
and administrative costs. Certain corporate costs are not allocated, including
corporate facility costs; non-allocated corporate salaries, benefits and
incentive compensation; acquisition and integration costs; non-cash stock-based
compensation; amortization related to intangible assets; asset impairments
related to goodwill and intangible assets; and change in fair value of
contingent consideration liabilities.

The following table sets forth segment revenues, segment operating income (loss) and operating margins for the periods indicated, as well as the dollar and percentage change from the prior period (dollars in thousands):

Electric Power Infrastructure Solutions Segment Results



Revenues. The increase in revenues for the year ended December 31, 2022 was
primarily due to increased spending by our utility customers on grid
modernization and hardening, resulting in increased demand for our electric
power services, as well as approximately $280 million in revenues attributable
to acquired businesses. This increase was partially offset by approximately $145
million in lower emergency restoration services revenues and foreign exchange
impacts of approximately $23 million.

Operating Income. Operating income increased for the year ended December 31,
2022 primarily due to the increase in revenues explained above. Operating margin
decreased during the year ended December 31, 2022 from lower equipment
utilization and fixed cost absorption and less favorable results associated with
inefficiencies attributable to supply chain disruptions impacting certain
operations, and elevated consumable costs. Lower emergency restoration services
revenues, which generally deliver higher margin, also contributed to the
decrease in operating margin, as well as less favorable results associated with
variability across our portfolio of projects. The decrease in operating margin
was partially offset by improved performance on various communication projects
in 2022, and the absence of losses associated with certain communication
projects in 2021 from various production issues, poor subcontractor performance,
challenging site conditions, permitting delays, increased completion costs and
adverse weather impacts. Equity in earnings from LUMA and other integral
unconsolidated affiliates increased $8.4 million in 2022 as compared to the year
ended December 31, 2021.

Renewable Energy Infrastructure Solutions Segment Results

Revenues. The increase in revenues for the year ended December 31, 2022 was primarily due to approximately $1.51 billion in revenues attributable to acquired businesses, primarily Blattner, which was acquired in October 2021. The remaining


                                       47
--------------------------------------------------------------------------------

increase in revenues was primarily due to increased customer demand for renewable transmission and interconnection construction services. These increases were partially offset by foreign exchange impacts of approximately $25 million.



Operating Income. The increase in operating income was primarily due to the
increase in revenues associated with the acquisition of Blattner. The decrease
in operating margin was attributable to lower margins on a large renewable
transmission project in Canada, a change in the mix of work due to acquisitions,
primarily Blattner, project delays and operating inefficiencies due to
regulatory and supply chain challenges in the utility scale solar industry and
less favorable results associated with normal variability in overall project
timing. Partially offsetting these decreases, operating margin improved relative
to 2021 as a result of a large renewable transmission project in the United
States. Operating income for the renewable segment also included $11.7 million
of asset impairment charges related to a software implementation project at an
acquired company, which commenced prior to our acquisition and was discontinued
in the fourth quarter of 2022. Additionally, there were favorable close-outs of
certain projects during the year ended December 31, 2021 as compared to the year
ended December 31, 2022.

Underground Utility and Infrastructure Solutions Segment Results



Revenues. The increase in revenues for the year ended December 31, 2022 was
primarily due to increased revenues associated with higher demand from our gas
utility and industrial customers, which began to move forward with certain
deferred maintenance and capital spending during the year ended December 31,
2022, as well as an increase in revenues associated with large pipeline projects
in Canada and Australia and approximately $40 million in revenues attributable
to acquired businesses. These increases were partially offset by foreign
exchange impacts of approximately $62 million.

Operating Income. The increase in operating income and operating margin for the
year ended December 31, 2022 was primarily due to the increase in revenues,
which contributed to higher levels of fixed cost absorption. Also contributing
to the increase were improved performance across the segment from better project
execution and resource utilization, particularly with respect to our industrial
services operations and large pipeline services in Canada, and more favorable
results associated with normal variability in overall project timing and project
mix. Additionally, our performance in this segment was impacted less by the
COVID-19 pandemic and challenges in the overall energy market during the year
ended December 31, 2022 as compared to the year ended December 31, 2021. Also
contributing to the increase in 2022 compared to 2021 was the recognition of a
specific provision for credit loss of $31.7 million recorded in 2021.

Corporate and Non-Allocated Costs



The increase in corporate and non-allocated costs during the year ended
December 31, 2022 was primarily due to a $188.6 million increase in intangible
asset amortization, largely associated with the acquisition of Blattner, and an
increase in compensation expense along with general and administrative expenses
resulting from the growth of the business. These increases were partially offset
by a $23.0 million decrease in expense related to deferred compensation
liabilities due to market fluctuations.


Non-GAAP Financial Measures

EBITDA and Adjusted EBITDA

EBITDA and adjusted EBITDA, financial measures not recognized under GAAP, when
used in connection with net income attributable to common stock, are intended to
provide useful information to investors and analysts as they evaluate our
performance. EBITDA is defined as earnings before interest and other financing
expenses, taxes, depreciation and amortization, and adjusted EBITDA is defined
as EBITDA adjusted for certain other items as described below. These measures
should not be considered as an alternative to net income attributable to common
stock or other financial measures of performance that are derived in accordance
with GAAP. Management believes that the exclusion of these items from net income
attributable to common stock enables Quanta and its investors to more
effectively evaluate our operations period over period and to identify operating
trends that might not be apparent when including the excluded items.

As to certain of the items below, (i) non-cash stock-based compensation expense
varies from period to period due to acquisition activity, changes in the
estimated fair value of performance-based awards, forfeiture rates, accelerated
vesting and amounts granted; (ii) acquisition and integration costs vary from
period to period depending on the level of our acquisition activity; (iii)
equity in (earnings) losses of non-integral unconsolidated affiliates varies
from period to period depending on the activity and financial performance of
such affiliates, the operations of which are not operationally integral to us;
(iv) unrealized mark-to-market adjustments on our investment in a publicly
traded company vary from period to period based on fluctuations in the market
price of such company's common stock; (v) gains and losses on the sale of
investments vary from period to period depending on activity; (vi) asset
impairment charges vary from period to period depending on economic and other
factors; and (vii) change in fair value of contingent consideration liabilities
varies from period to period depending on the performance in
                                       48

post-acquisition periods of certain acquired businesses and the effect of
present value accretion on fair value calculations. Because EBITDA and adjusted
EBITDA, as defined, exclude some, but not all, items that affect net income
attributable to common stock, such measures may not be comparable to similarly
titled measures of other companies. The most comparable GAAP financial measure,
net income attributable to common stock, and information reconciling the GAAP
and non-GAAP financial measures, are included below. The following table shows
dollars in thousands.

(2) The amount for the year ended December 31, 2022 is an unrealized loss from a
decrease in fair value of our investment in Starry, as further described in Note
8 of the Notes to Consolidated Financial Statements in Item 8. Financial
Statements and Supplementary Data of this Annual Report.

(3) The amount for the year ended December 31, 2022 is a gain as a result of the
sale of a non-integral equity method investment further described in Note 8 of
the Notes to Consolidated Financial Statements in Item 8. Financial Statements
and Supplementary Data of this Annual Report, and a non-marketable equity
security interest in a technology company.

(4) The amount for the year ended December 31, 2022 primarily relates to an impairment of a software implementation project, which was discontinued during the fourth quarter of 2022.

Remaining Performance Obligations and Backlog



A performance obligation is a promise in a contract with a customer to transfer
a distinct good or service. Our remaining performance obligations represent
management's estimate of consolidated revenues that are expected to be realized
from the remaining portion of firm orders under fixed price contracts not yet
completed or for which work has not yet begun, which includes estimated revenues
attributable to consolidated joint ventures and variable interest entities,
revenues from funded and unfunded portions of government contracts to the extent
they are reasonably expected to be realized, and revenues from change orders and
claims to the extent management believes they will be earned and are probable of
collection.

We have also historically disclosed our backlog, a measure commonly used in our
industry but not recognized under GAAP. We believe this measure enables
management to more effectively forecast our future capital needs and results and
better identify future operating trends that may not otherwise be apparent. We
believe this measure is also useful for investors in forecasting our future
results and comparing us to our competitors. Our remaining performance
obligations are a component of backlog, which also includes estimated orders
under MSAs, including estimated renewals, and non-fixed price contracts expected
to be completed within one year. Our methodology for determining backlog may not
be comparable to the methodologies used by other companies.
                                       49
--------------------------------------------------------------------------------

As of December 31, 2022 and 2021, MSAs accounted for 52% and 55% of our
estimated 12-month backlog and 65% and 67% of our total backlog. Generally, our
customers are not contractually committed to specific volumes of services under
our MSAs, and most of our contracts can be terminated on short notice even if we
are not in default. We determine the estimated backlog for these MSAs using
recurring historical trends, factoring in seasonal demand and projected customer
needs based upon ongoing communications. In addition, many of our MSAs are
subject to renewal, and these potential renewals are considered in determining
estimated backlog. As a result, estimates for remaining performance obligations
and backlog are subject to change based on, among other things, project
accelerations; project cancellations or delays, including but not limited to
those caused by commercial issues, regulatory requirements, natural disasters,
emergencies (including the COVID-19 pandemic) and adverse weather conditions;
and final acceptance of change orders by customers. These factors can cause
revenues to be realized in periods and at levels that are different than
originally projected.

The following table reconciles total remaining performance obligations to our
backlog (a non-GAAP financial measure) by reportable segment, along with
estimates of amounts expected to be realized within 12 months (in thousands):

The increase in remaining performance obligations from December 31, 2021 to December 31, 2022 was attributable to multiple new project awards, while the increase in backlog was attributable to these new awards and extensions and increases in expected volumes under MSAs.

Liquidity and Capital Resources



Management monitors financial markets and national and global economic
conditions for factors that may affect our liquidity and capital resources. As
set forth below, we have various short-term and long-term cash requirements and
capital allocation priorities, and we intend to fund these requirements
primarily with cash flow from operating activities, as well as debt financing as
needed.

$ 4,502,734 $ 4,878,208




(1)  Amounts represent cash interest and other financing expenses associated
primarily with our senior notes. Interest payments related to our senior credit
facility and notes issued under our commercial paper program are not included
due to their variable interest rates, and as it relates to the commercial paper
program, the short-term nature of the borrowings. With respect to this variable
rate debt, assuming the principal amount outstanding and interest rate in effect
as of December 31, 2022 remained the same, the annual cash interest expense
would be approximately $65.0 million, payable until October 8, 2026, the
maturity date of our senior credit facility.
(2)  Amounts represent undiscounted operating and finance lease obligations as
of December 31, 2022. The corresponding amounts recorded on our December 31,
2022 consolidated balance sheet represent the present value of these amounts.
(3)  Amounts represent undiscounted operating lease obligations that have not
commenced as of December 31, 2022. The operating lease obligations will be
recorded on our consolidated balance sheet beginning on the commencement date of
each lease.
(4) Amounts represent lease financing transactions as further described in Note
11 of the Notes to Consolidated Financial Statements in Item 8. Financial
Statements and Supplementary Data of this Annual Report.
(5) Amounts represent capital committed for the expansion of our vehicle fleet.
Although we have committed to the purchase of these vehicles/equipment at the
time of their delivery, we expect that these orders will be assigned to
third-party leasing companies and made available to us under certain of our
master equipment lease agreements.

Contingent Obligations. We have various contingent obligations that could require the use of cash or impact the collection of cash in future periods; however, we are unable to accurately predict the timing and estimate the amount of such contingent obligations as of December 31, 2022. These contingent obligations generally include, among other things:



•contingent consideration liabilities, which are described further in Note 6 of
the Notes to Consolidated Financial Statements in Item 8. Financial Statements
and Supplementary Data of this Annual Report;

•undistributed earnings of foreign subsidiaries and unrecognized tax benefits,
which are described further in Note 12 of the Notes to Consolidated Financial
Statements in Item 8. Financial Statements and Supplementary Data of this Annual
Report;

•collective bargaining agreements and multiemployer pension plan liabilities, as
well as liabilities related to our deferred compensation and other employee
benefit plans, which are described further in Notes 15 and 16 of the Notes to
Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report; and

•obligations relating to our joint ventures, lawsuits and other legal
proceedings, uncollectible accounts receivable, insurance liabilities,
obligations relating to letters of credit, bonds and parent guarantees,
obligations relating to employment agreements, indemnities and assumed
liabilities, and residual value guarantees, which are described further in Notes
4, 10, 11 and 16 of the Notes to Consolidated Financial Statements in Item 8.
Financial Statements and Supplementary Data of this Annual Report.

Capital Allocation. Our capital deployment priorities that require the use of
cash include: (i) working capital to fund ongoing operating needs, (ii) capital
expenditures to meet anticipated demand for our services, (iii) acquisitions and
investments
                                       51
--------------------------------------------------------------------------------

to facilitate the long-term growth and sustainability of our business, and (iv)
return of capital to stockholders, including through the payment of dividends
and repurchases of our outstanding common stock. Our industry is capital
intensive, and we expect substantial capital expenditures and commitments for
equipment purchases and equipment lease and rental arrangements to be needed
into the foreseeable future in order to meet anticipated demand for our
services. We expect capital expenditures for property and equipment purchases
for the year ended December 31, 2023 to be approximately $400 million. We also
expect to continue to allocate significant capital to strategic acquisitions and
investments, as well as to pay dividends and to repurchase our outstanding
common stock and/or debt securities. In January of 2023, we completed the
acquisition of three businesses in which a portion of the consideration
consisted of $465.0 million in cash funded with a combination of cash and cash
equivalents and borrowings from our commercial paper program. For additional
information regarding these acquisitions, refer to Note 6 of the Notes to
Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report.

Significant Sources of Cash



We anticipate that our future cash flows from operating activities, cash and
cash equivalents on hand, existing borrowing capacity under our senior credit
facility and commercial paper program and ability to access capital markets for
additional capital will provide sufficient funds to enable us to meet our cash
requirements described above for the next twelve months and over the longer
term.

Cash flow from operating activities is primarily influenced by demand for our
services and operating margins but is also influenced by the timing of working
capital needs associated with the various types of services that we provide. Our
working capital needs may increase when we commence large volumes of work under
circumstances where project costs are required to be paid before the associated
receivables are billed and collected. Additionally, operating cash flows may be
negatively impacted as a result of unpaid and delayed change orders and claims.
Changes in project timing due to delays or accelerations and other economic,
regulatory, market and political factors that may affect customer spending could
also impact cash flow from operating activities. Further information with
respect to our cash flow from operating activities is set forth below and in
Note 18 of the Notes to Consolidated Financial Statements in Item 8. Financial
Statements and Supplementary Data of this Annual Report.

Our available commitments under our senior credit facility and cash and cash equivalents as of December 31, 2022 were as follows (in thousands):

December 31, 2022 Total capacity available for revolving loans, credit support for commercial paper program and letters of credit

$        2,640,000
Less:
Borrowings of revolving loans                                                               36,910
Commercial paper program notes outstanding (1)                                             373,000

Available commitments for revolving loans, credit support for commercial paper program and letters of credit

Total available commitments under senior credit facility and cash and cash equivalents

$ 2,430,759




(1) Represents unsecured notes issued under our commercial paper program, which
allows for the issuance of notes up to a maximum aggregate face amount of $1.0
billion outstanding at any time. Available commitments for revolving loans under
our senior credit facility must be maintained to provide credit support for
notes issued under our commercial paper program, and therefore such notes
effectively reduce the available borrowing capacity under our senior credit
facility.

(2) Further information with respect to our cash and cash equivalents is set
forth in Note 17 of the Notes to Consolidated Financial Statements in Item 8.
Financial Statements and Supplementary Data of this Annual Report.

We consider our investment policies related to cash and cash equivalents to be
conservative, as we maintain a diverse portfolio of what we believe to be
high-quality cash and cash equivalent investments with short-term maturities.
Additionally, subject to the conditions specified in the credit agreement for
our senior credit facility, we have the option to increase the capacity of our
senior credit facility, in the form of an increase in the revolving commitments,
term loans or a combination thereof, from time to time, upon receipt of
additional commitments from new or existing lenders by up to an additional (i)
$400.0 million plus (ii) additional amounts so long as the Incremental Leverage
Ratio Requirement (as defined in the credit
                                       52
--------------------------------------------------------------------------------

agreement) is satisfied at the time of such increase. The Incremental Leverage
Ratio Requirement requires, among other things, after giving pro forma effect to
such increase and the use of proceeds therefrom, compliance with the credit
agreement's financial covenants as of the most recent fiscal quarter end for
which financial statements were required to be delivered. Further information
with respect to our debt obligations is set forth in Note 10 of the Notes to
Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report.

We may also seek to access the capital markets from time to time to raise
additional capital, increase liquidity as necessary, refinance or extend the
term of our existing indebtedness, fund acquisitions or otherwise fund our
capital needs. While our financial strategy and consistent performance have
allowed us to maintain investment grade ratings, our ability to access capital
markets in the future depends on a number of factors, including our financial
performance and financial position, our credit ratings, industry conditions,
general economic conditions, our backlog, capital expenditure commitments,
market conditions and market perceptions of us and our industry.

Sources and Uses of Cash, Cash Equivalents and Restricted Cash During the Years Ended December 31, 2022 and 2021

In summary, our cash flows for each period were as follows (in thousands):



                                                               Year Ended 

December 31,


                                                                2022        

2021


 Net cash provided by operating activities                $    1,130,312

$ 582,390


 Net cash used in investing activities                          (617,191)   

(2,898,613)


 Net cash (used in) provided by financing activities            (311,071)        2,360,877


Operating Activities

Net cash provided by operating activities of $1.13 billion and $582.4 million in
2022 and 2021 primarily reflected earnings adjusted for non-cash items and cash
used by the main components of working capital: "Accounts and notes receivable,"
"Contract assets," "Accounts payable and accrued expenses," and "Contract
liabilities."

Certain payments negatively impacted net cash provided by operating activities
in both the years ended December 31, 2022 and 2021, including $45.4 million and
$72.3 million related to certain change of control liabilities owed to employees
of Blattner and payable in connection with our acquisition of Blattner; $11.0
million and $37.4 million of cash payments for other acquisition and integration
costs; and $54.4 million in each period for payments associated with deferred
employer payroll taxes, which were due during the year ended December 31, 2020
but deferred pursuant to the Coronavirus Aid, Relief, and Economic Security Act
(CARES Act). Partially offsetting these negative impacts in 2022 was the receipt
of $100.5 million pursuant to coverage under an insurance policy following a
legal proceeding, as further described in Legal Proceedings - Peru Project
Dispute in Note 16 of the Notes to Consolidated Financial Statements in Item 8.
Financial Statements and Supplementary Data of this Annual Report.

As discussed above, cash flow from operating activities is primarily influenced
by demand for our services and operating margins but is also influenced by
working capital needs. Our working capital needs may increase when we commence
large volumes of work under circumstances where project costs, primarily labor,
equipment and subcontractors, are required to be paid before the associated
receivables are billed and collected and when we incur costs for work that is
the subject of unpaid change orders and claims. Accordingly, changes within
working capital in accounts receivable, contract assets and contract liabilities
are normally related and are typically affected on a collective basis by changes
in revenue due to the timing and volume of work performed and variability in the
timing of customer billings and payments. Additionally, working capital needs
are generally higher during the summer and fall due to increased demand for our
services when favorable weather conditions exist in many of our operating
regions. Conversely, working capital assets are typically converted to cash
during the winter. These seasonal trends can be offset by changes in project
timing due to delays or accelerations and other economic factors that may affect
customer spending, including market conditions or the impact of certain
unforeseen events (e.g., regulatory and other actions that impact the supply
chain for certain materials).

Days sales outstanding (DSO) represents the average number of days it takes
revenues to be converted into cash, which management believes is an important
metric for assessing liquidity. A decrease in DSO has a favorable impact on cash
flow from operating activities, while an increase in DSO has a negative impact
on cash flow from operating activities. DSO is calculated by using the sum of
current accounts receivable, net of allowance (which includes retainage and
unbilled balances), plus contract assets less contract liabilities, divided by
average revenues per day during the quarter. DSO at December 31, 2022 was 75
days, which was lower than DSO of 80 days at December 31, 2021 and our five-year
historical average DSO of 82 days. This decrease in DSO as compared to
December 31, 2021 was primarily due to favorable billing positions on certain
projects.
                                       53
--------------------------------------------------------------------------------

This decrease was partially offset by high working capital requirements primarily related to a large renewable transmission project in Canada and the timing of the associated billings.

Investing Activities



Net cash used in investing activities in 2022 included $427.6 million of capital
expenditures; $195.1 million related to acquisitions, primarily related to a net
working capital adjustment in connection with our acquisition of Blattner; and
$78.1 million of cash paid primarily for equity method investments and
non-marketable securities. Partially offsetting these items were $62.1 million
of proceeds from the sale of property and equipment and $20.6 million of cash
received from sale of investments.

Net cash used in investing activities in 2021 included $2.45 billion used for
acquisitions, most of which relates to our acquisition of Blattner; $385.9
million of capital expenditures; and $139.0 million of cash paid for equity and
other investments, which was primarily related to the acquisition of our initial
minority interest in Starry. These items were partially offset by $49.2 million
of proceeds from the sale of property and equipment and $29.1 million of cash
received primarily from sale of investments.

Our industry is capital intensive, and we expect substantial capital
expenditures and commitments for equipment purchases and equipment lease and
rental arrangements to be needed for the foreseeable future in order to meet
anticipated demand for our services. In addition, we expect to continue to
pursue strategic acquisitions and investments, although we cannot predict the
timing or amount of the cash needed for these initiatives. We also have various
other capital commitments that are detailed in Cash Requirements and Capital
Allocation above.

Financing Activities

Net cash used in financing activities in the year ended December 31, 2022
included $127.8 million common stock repurchases; $82.6 million payments to
satisfy tax withholding obligations associated with stock-based compensation;
$41.1 million of dividends; $23.4 million of net repayments under our senior
credit facility and commercial paper program; $15.7 million of net repayments of
short-term debt; and $9.7 million of distributions to non-controlling interests.

Net cash provided by financing activities in 2021 included $1.49 billion of net
proceeds from the issuance of the 0.950% senior notes due October 2024, the
2.350% senior notes due January 2032 and the 3.050% senior notes due October
2041, net of the original issue discount and underwriting discounts but not net
of deferred financing costs paid or accrued by us. On October 13, 2021, we
borrowed the full amount of a $750.0 million term loan facility under our senior
credit facility and used such amount, together with the net proceeds from our
September 2021 offering of the senior notes and approximately $50.9 million of
revolving loans borrowed under our senior credit facility, to pay the cash
consideration for the acquisition of Blattner. Total net borrowings under our
senior credit facility during the year ended December 31, 2021 were $1.05
billion, which included the $750.0 million term loan facility. Deferred
financing costs paid directly by us during the year ended December 31, 2021 were
$12.6 million, $8.2 million of which related to the September 2021 issuance of
such senior notes, the term loan and amendment of our senior credit facility and
$4.4 million of which related to the bridge facility commitment entered into,
but ultimately not utilized, in connection with our acquisition of Blattner. Net
cash provided by financing activities in 2021 also included $11.4 million of net
borrowings of short-term debt.

Net cash provided by financing activities in 2021 was partially offset by $66.7
million of cash payments for common stock repurchases, $65.0 million of cash
payments to satisfy tax withholding obligations associated with stock-based
compensation and $34.0 million of cash payments for dividends and cash dividend
equivalents.

We expect to continue to utilize cash for similar financing activities in the
future, including repayments under our senior credit facility and commercial
paper program, payment of cash dividends and repurchases of our common stock
and/or debt securities.

Critical Accounting Estimates



The discussion and analysis of our financial condition and results of operations
are based on our consolidated financial statements, which have been prepared in
accordance with GAAP. The preparation of these consolidated financial statements
requires us to make estimates and assumptions that affect the reported amounts
of assets and liabilities, disclosures of contingent assets and liabilities
known to exist as of the date the consolidated financial statements are
published and the reported amounts of revenues and expenses recognized during
the periods presented. We review all significant estimates affecting our
consolidated financial statements on a recurring basis and record the effect of
any necessary adjustments prior to their publication. Judgments and estimates
are based on our beliefs and assumptions derived from information available at
the time such judgments and estimates are made. Uncertainties with respect to
such estimates and assumptions are inherent in the preparation of financial
statements. There can be no assurance that actual results will not differ from
those estimates.
                                       54

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



Management has reviewed its development and selection of critical accounting
estimates with the audit committee of our Board of Directors. Our accounting
policies are primarily described in Note 2 of the Notes to Consolidated
Financial Statements in Item 8. Financial Statements and Supplementary Data of
this Annual Report and should be read in conjunction with the accounting
policies identified below that we believe affect our more significant judgments
and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition - The estimation of contract revenues and costs, including
changes in estimates; progress on construction projects; variable consideration;
and collectability of accounts receivable, long-term accounts receivable,
unbilled receivables, retainage and contract assets, including amounts related
to unapproved change orders and claims in the process of being negotiated (refer
to Note 4 of the Notes to Consolidated Financial Statements in Item 8. Financial
Statements and Supplementary Data of this Annual Report).

Property and Equipment - The valuation methods and assumptions used in assessing
impairment, useful life determination and the related timing of depreciation and
the determination of asset groupings (also refer to Note 17 of the Notes to
Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report).

Goodwill - The valuation methods and assumptions used in assessing impairment,
including determination of whether to perform a qualitative assessment on some
or all of the reporting units, weighting of various methods of determining the
fair value of each reporting unit, number of years of cash flows utilized before
applying a terminal value, the weighted average cost of capital, transaction
multiples, guideline public company multiples and five-year compounded annual
growth rates.

Other Intangible Assets - The valuation methods and assumptions used in
assessing the fair value of intangible assets as of the date a business is
acquired, as well as any impairment, including determining the future revenues,
discount rates and customer attrition rates (also refer to Note 6 of the Notes
to Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report).

Income Taxes - The identification and measurement of deferred tax assets and
liabilities; the measurement of valuation allowances on deferred tax assets
including estimates of future taxable income; estimates associated with tax
liabilities in that tax laws and regulations are voluminous and often ambiguous;
and benefits from uncertain tax positions (also refer to Note 12 of the Notes to
Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report).

Insurance - The estimation of liabilities and related recoveries (also refer to
Note 16 of the Notes to Consolidated Financial Statements in Item 8. Financial
Statements and Supplementary Data of this Annual Report).

Litigation Costs and Reserves and Loss Contingencies - The estimation of when a
loss is probable or reasonably possible and whether any such loss is reasonably
estimable or any range of possible loss is estimable, as well as uncertainties
related to the outcome of litigation or other legal proceedings (also refer to
Note 16 of the Notes to Consolidated Financial Statements in Item 8. Financial
Statements and Supplementary Data of this Annual Report).

Acquisitions - The assumptions used to determine the fair value of consideration
transferred and to allocate this consideration to assets acquired and
liabilities assumed in connection with our acquisitions, including the estimated
useful lives of other intangible assets subject to amortization and the fair
value of contingent consideration liabilities (also refer to Note 6 of the Notes
to Consolidated Financial Statements in Item 8. Financial Statements and
Supplementary Data of this Annual Report).

Stock-based Compensation - The assumptions used to determine the grant date fair
value and attainment percentages related to performance stock units (also refer
to Note 14 of the Notes to Consolidated Financial Statements in Item 8.
Financial Statements and Supplementary Data of this Annual Report).
