Driven by the dedication and operational excellence of our world-class employees, we believe our 2022 results also demonstrate the benefit of our diversified portfolio of solutions, our repeatable and sustainable model and the successful execution of our strategic initiatives that are driving operational excellence and total cost solutions for our clients,” said Duke Austin, President and Chief Executive Officer of Quanta Services. “Our growing cash flow and strong financial profile, coupled with our visible, robust end-market dynamics, position us well to continue to deliver value for our stakeholders.

“Our 2023 expectations reflect the opportunity for continued growth in revenues, adjusted EBITDA, adjusted earnings per share and cash flow. Further, we are increasingly excited and confident about the opportunity to drive multi-year revenue and double-digit earnings per share growth. As evidenced by our record backlog and the other recent highlights we announced this morning, demand is strong for our infrastructure solutions that support our customers’ energy-transition initiatives and increase reliability, safety, efficiency and connectivity through modernization. For many years Quanta has incrementally invested in and developed industry-leading safety and training for our employees, which has made us an employer of choice in our industry and supports our future growth and success.

Certain items impacted Quanta’s results for 2022 and 2021 and are reflected as adjustments in the calculation of Quanta’s adjusted diluted earnings per share attributable to common stock (a non-GAAP measure). These items are described in the accompanying tables reconciling adjusted diluted earnings per share attributable to common stock to GAAP diluted earnings per share attributable to common stock. Quanta completed one acquisition during 2022 and ten acquisitions during 2021, and the results of the acquired businesses are included in Quanta’s consolidated results from the respective acquisition dates. For further information on the items that impacted comparability of 2022 and 2021, see the footnotes accompanying tables presenting Supplemental Segment Data and reconciliations of adjusted EBITDA and adjusted diluted earnings per share attributable to common stock (non-GAAP measures) to their comparable GAAP financial measures.

Preconstruction activities have begun and construction on the first segment is scheduled to begin in mid-2023. Quanta included the estimated revenue for the project in remaining performance obligations and backlog for the Renewable Energy Infrastructure Solutions segment as of December 31, 2022.

• Capital Deployment - In January 2023, Quanta acquired three businesses that primarily enhance Quanta’s ability to deliver comprehensive infrastructure solutions to utility and renewable energy customers in the United States for aggregate consideration of approximately $588.5 million, subject to certain post-closing adjustments. During the fourth quarter of 2022, Quanta also repurchased 86,319 shares of its outstanding common stock in the open market for $11.4 million, and for the year ended December 31, 2022, Quanta repurchased 1,060,997 shares of its outstanding common stock in the open market for $127.7 million. Quanta currently has authorization under its existing stock repurchase program to acquire an additional $345.1 million of its common stock. Additionally, in December 2022, Quanta’s Board of Directors declared a quarterly cash dividend to stockholders of $0.08 per share, or a rate of $0.32 per share on an annualized basis, which represents a 14% increase from Quanta’s prior quarterly cash dividend paid in October 2022.

RESULTS FOR THE YEARS ENDED DECEMBER 31, 2022 AND 2021

Revenues in the year ended December 31, 2022 were $17.07 billion compared to revenues of $12.98 billion in the year ended December 31, 2021, and net income attributable to common stock was $491.2 million, or $3.32 per diluted share, in the year ended December 31, 2022 compared to net income attributable to common stock of $486.0 million, or $3.34 per diluted share, in the year ended December 31, 2021. Adjusted diluted earnings per share attributable to common stock (a non-GAAP measure) was $6.34 for the year ended December 31, 2022 compared to $4.91 for the year ended December 31, 2021.

FULL-YEAR 2023 OUTLOOK

The long-term outlook for Quanta’s business is positive. However, weather, regulatory, permitting, supply chain challenges and other factors affecting project timing and execution have impacted, and may impact in the future, Quanta’s financial results. Additionally, we continue to consider future uncertainty associated with overall challenges to the domestic and global economy, including inflation, increased interest rates and recessionary economic conditions. Quanta’s financial outlook for revenues, margins and earnings reflects management’s effort to align these uncertainties with the backlog (a non-GAAP measure) the Company is executing on and the opportunities expected to materialize during 2023.

Prior to the Company’s conference call, management will post a summary of Quanta’s 2023 guidance expectations with additional commentary in the “News and Events” and “Financial Info” areas of the Investor Relations section of Quanta’s website at http://investors.quantaservices.com.

Remaining Performance Obligations and Backlog (a non-GAAP financial measure)

Quanta’s 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.

Quanta has also historically disclosed its backlog, a measure commonly used in its industry but not recognized under GAAP. Quanta believes this measure enables management to more effectively forecast its future capital needs and results and better identify future operating trends that may not otherwise be apparent. Quanta believes this measure is also useful for investors in forecasting Quanta’s future results and comparing Quanta to its competitors. Quanta’s remaining performance obligations, as described above, are a component of its backlog calculation, which also includes estimated orders under master service agreements (MSAs), including estimated renewals, and non-fixed price contracts expected to be completed within one year. Quanta’s methodology for determining backlog may not be comparable to the methodologies used by other companies.

The following table reconciles Quanta’s total remaining performance obligations to its backlog by reportable segment along, with estimates of amounts expected to be realized within 12 months:

Quanta Services, Inc. and Subsidiaries Reconciliation of Non-GAAP Financial Measures Adjusted Net Income and Adjusted Diluted Earnings Per Share Attributable to Common Stock For the Three and Twelve Months Ended December 31, 2022 and 2021 (In thousands, except per share information) (Unaudited)

The following table presents the reconciliations of the non-GAAP financial measures of adjusted net income attributable to common stock to net income attributable to common stock and adjusted diluted earnings per share attributable to common stock to diluted earnings per share attributable to common stock for the three and twelve months ended December 31, 2022 and 2021. These reconciliations are intended to provide useful information to investors and analysts as they evaluate Quanta’s performance. Management believes that the exclusion of certain items from net income attributable to common stock and diluted earnings per share attributable to common stock enables it and Quanta’s investors to more effectively evaluate Quanta’s operations period over period and better identify operating trends that may not otherwise be apparent. However, these non-GAAP measures should not be considered as alternatives to net income attributable to common stock and diluted earnings per share attributable to common stock or other measures of performance that are derived in accordance with GAAP.

As to certain of the items in the table: (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) amortization of intangible assets and amortization included in equity in earnings are impacted by Quanta’s acquisition activities and investments in integral unconsolidated affiliates, and therefore can vary from period to period; (iii) acquisition and integration costs vary from period to period depending on the level of Quanta’s acquisition activity; (iv) asset impairment charges vary from period to period depending on economic and other factors; (v) change in fair value of contingent consideration liabilities varies from period to period depending on the performance in post-acquisition periods of certain acquired businesses and the effect of present value accretion on fair value calculations; (vi) 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 Quanta; (vii) unrealized mark-to-market adjustments on Quanta’s investment in a publicly traded company vary from period to period based on fluctuations in the market price of such company’s common stock; (viii) gains and losses on the sales of investments vary from period to period depending on activity; and (ix) write-offs of deferred financing costs vary from period to period depending on the timing and nature of debt and other financing transactions.

Beginning with the period ended June 30, 2022, adjusted net income attributable to common stock and adjusted diluted earnings per share attributable to common stock exclude the impact of equity in (earnings) losses of non-integral unconsolidated affiliates. Management believes that excluding the impact of this item allows Quanta’s investors and management to more effectively evaluate Quanta’s operations between periods and identify operating trends, since the results of these unconsolidated affiliates’ operations are not operationally integral to those of Quanta. As a result of this change, the calculation of adjusted net income attributable to common stock and adjusted diluted earnings per share attributable to common stock for the three and twelve months ended December 31, 2021 has been recast to conform to the current presentation. Because adjusted net income attributable to common stock and adjusted diluted earnings per share attributable to common stock, as defined, exclude some, but not all, items that affect net income attributable to common stock and diluted earnings per share attributable to common stock, they may not be comparable to similarly titled measures of other companies. The most comparable GAAP financial measures, net income attributable to common stock and diluted earnings per share attributable to common stock, and information reconciling the GAAP and non-GAAP financial measures, are included in the table to follow.

Quanta Services, Inc. and Subsidiaries Reconciliation of Non-GAAP Financial Measures EBITDA and Adjusted EBITDA For the Three and Twelve Months Ended December 31, 2022 and 2021 (In thousands) (Unaudited)

The following table presents reconciliations of the non-GAAP financial measures of EBITDA and adjusted EBITDA to net income attributable to common stock for the three and twelve months ended December 31, 2022 and 2021. These reconciliations are intended to provide useful information to investors and analysts as they evaluate Quanta’s 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 it and Quanta’s investors to more effectively evaluate Quanta’s 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 Quanta’s 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 Quanta; (iv) unrealized mark-to-market adjustments on Quanta’s 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 can 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 post-acquisition periods of certain acquired businesses and the effect of present value accretion on fair value calculations.

Quanta Services, Inc. and Subsidiaries Reconciliation of Non-GAAP Financial Measures Free Cash Flow and Other Non-GAAP Definitions For the Three and Twelve Months Ended December 31, 2022 and 2021 (In thousands) (Unaudited)

Reconciliation of Free Cash Flow:

The following table presents a reconciliation of the non-GAAP financial measure of free cash flow to net cash provided by operating activities for the three and twelve months ended December 31, 2022 and 2021. This reconciliation is intended to provide useful information to investors and analysts as they evaluate Quanta’s ability to generate the cash required to maintain and potentially expand its business. Free cash flow is defined as net cash provided by operating activities less net capital expenditures. Net capital expenditures is defined as capital expenditures less proceeds from the sale of property and equipment and from insurance settlements related to property and equipment. Management believes that free cash flow provides useful information to Quanta’s investors because free cash flow is viewed by management as an important indicator of how much cash is provided or used by routine business operations, including the impact of net capital expenditures. Management uses this measure for capital allocation purposes as it is viewed as a measure of cash available to fund debt payments, acquire businesses, repurchase common stock and debt securities, declare and pay dividends and transact other investing and financing activities. However, this measure should not be considered as an alternative to net cash provided by operating activities or other measures of performance that are derived in accordance with GAAP. The most comparable GAAP financial measure, net cash provided by operating activities, and information reconciling the GAAP and non-GAAP financial measures, are included below.

	Three Months Ended December 31,						Twelve Months Ended December 31,
	2022			2021			2022			2021
Net cash provided by operating activities (a)	$	583,129		$	249,953		$	1,130,312		$	582,390
Less: Net capital expenditures:
Capital expenditures		(90,161	)		(152,856	)		(427,630	)		(385,852	)
Cash proceeds from sale of property and equipment and related insurance settlements		20,520			14,085			64,123			49,721
Net capital expenditures		(69,641	)		(138,771	)		(363,507	)		(336,131	)
Free Cash Flow	$	513,488		$	111,182		$	766,805		$	246,259

(a) Amounts for each of the three and twelve months ended December 31, 2022 and 2021 include $54.4 million due to two equal payments made related to the deferral in 2020 of $108.9 million of the employer portion of payroll taxes pursuant to the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). Amounts also include payments related to certain change in control liabilities in connection with Quanta’s acquisition of Blattner of $45.4 million for the three and twelve months ended December 31, 2022 and $72.3 million for the three and twelve months ended December 31, 2021. Amounts also include cash payments for acquisition and integration costs of $2.2 million and $27.9 million for the three months ended December 31, 2022 and 2021 and $11.0 million and $37.4 million for the twelve months ended December 31, 2022 and 2021. Amounts for the three and twelve months ended December 31, 2022 includes the receipt of $100.5 million under an insurance policy following a favorable arbitration ruling associated with our Peruvian subsidiary’s terminated telecommunications project.

Other Non-GAAP Definitions:

Days Sales Outstanding:

Days Sales Outstanding is calculated by using the sum of current accounts receivable (which includes retainage and unbilled balances), net of allowance, plus contract assets, less contract liabilities, and divided by average revenues per day during the quarter.

Total Liquidity:

Total liquidity includes Quanta’s cash and cash equivalents and availability under Quanta’s senior credit facility. Available commitments for revolving loans under the senior credit facility must be maintained in order to provide credit support for notes issued under the commercial paper program, and therefore such notes effectively reduce the available borrowing capacity under the senior credit facility.

As to certain of the items below, (i) non-cash stock-based compensation expense may vary 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) amortization of intangible assets and amortization included in equity in earnings are impacted by Quanta’s acquisition activities and investments in integral unconsolidated affiliates, and therefore can vary from period to period; and (iii) acquisition and integration costs vary from period to period depending on the level of Quanta’s acquisition activity. Because adjusted net income attributable to common stock and adjusted diluted earnings per share attributable to common stock, as defined, exclude some, but not all, items that affect net income attributable to common stock and diluted earnings per share attributable to common stock, they may not be comparable to similarly titled measures of other companies. The most comparable GAAP financial measures, net income attributable to common stock and diluted earnings per share attributable to common stock, and information reconciling the GAAP and non-GAAP financial measures, are included below.

Quanta Services, Inc. and Subsidiaries Reconciliation of Non-GAAP Financial Measures Estimated EBITDA and Adjusted EBITDA For the Full Year 2023 (In thousands) (Unaudited)

The following table presents the reconciliations of the non-GAAP financial measures of estimated EBITDA and adjusted EBITDA to net income attributable to common stock for the full year ending December 31, 2023. These reconciliations are intended to provide useful information to investors and analysts as they evaluate Quanta’s expected future 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 it and Quanta’s investors to more effectively evaluate Quanta’s 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 and (ii) acquisition and integration costs vary from period to period depending on the level of Quanta’s acquisition activity.

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 in the table to follow.

	Estimated Range

Quanta Services, Inc. and Subsidiaries Reconciliation of Non-GAAP Financial Measures Estimated Free Cash Flow For the Full Year 2023 (In thousands) (Unaudited)

The following table presents a reconciliation of the non-GAAP financial measure of estimated free cash flow to estimated net cash provided by operating activities for the full year ending December 31, 2023. This reconciliation is intended to provide useful information to investors and analysts as they evaluate Quanta’s expectations regarding its ability to generate the cash required to maintain and potentially expand its business. Free cash flow is defined as net cash provided by operating activities less net capital expenditures. Net capital expenditures is defined as capital expenditures less proceeds from the sale of property and equipment and from insurance settlements related to property and equipment. Management believes that free cash flow provides useful information to Quanta’s investors because free cash flow is viewed by management as an important indicator of how much cash is provided or used by routine business operations, including the impact of net capital expenditures. Management uses this measure for capital allocation purposes as it is viewed as a measure of cash available to fund debt payments, acquire businesses, repurchase common stock and debt securities, declare and pay dividends and transact other investing and financing activities. However, this measure should not be considered as an alternative to net cash provided by operating activities or other measures of performance that are derived in accordance with GAAP. The most comparable GAAP financial measure, net cash provided by operating activities, and information reconciling the GAAP and non-GAAP financial measures, are included below.

	Estimated Range
	Full Year Ending December 31, 2023
Net cash provided by operating activities	$	1,150,000		$	1,400,000
Less: Net capital expenditures		(400,000	)		(400,000	)
Free Cash Flow	$	750,000		$	1,000,000
