HOUSTON, Nov. 1, 2018 /PRNewswire/ -- Quanta Services, Inc. (NYSE: PWR) today announced results for the three and nine months ended September 30, 2018. Revenues in the third quarter of 2018 were $2.99 billion, compared to revenues of $2.61 billion in the third quarter of 2017, and net income attributable to common stock was $124.6 million, or $0.81 per diluted share, in the third quarter of 2018, compared to net income attributable to common stock of $89.3 million, or $0.56 per diluted share, in the third quarter of 2017. Adjusted diluted earnings per share attributable to common stock (a non-GAAP measure) was $0.88 for the third quarter of 2018 compared to $0.63 for the third quarter of 2017.

"Quanta achieved record quarterly revenues, adjusted EBITDA, adjusted earnings per share and backlog during the third quarter. We expect that 2018 will be a record year and believe we will end the year with an incrementally stronger fourth quarter as compared to our prior expectations. We are increasing our revenues and the midpoint of our adjusted EBITDA expectations and maintaining our adjusted earnings per share expectations for 2018. Importantly, strengthening demand across our business solidifies our outlook for earnings growth in 2019," said Duke Austin, President and Chief Executive Officer of Quanta Services. "We continue to strongly believe in the attractive near and long-term industry drivers of our business, as well as our growth opportunities and competitive position. As a result, we have repurchased more than $300 million of our common stock this year, which we believe demonstrates our continued commitment to enhancing stockholder value."

Certain items that impacted the third quarter of 2018 are reflected as adjustments in the calculation of Quanta's adjusted diluted earnings per share attributable to common stock and are further described in the reconciliation of adjusted diluted earnings per share attributable to common stock to GAAP diluted earnings per share attributable to common stock. Favorably impacting the third quarter 2018 results were net tax benefits of $9.1 million, or $0.06 per diluted share, related to the release of tax contingencies upon expiration of certain statute of limitations periods and an adjustment to provisional amounts Quanta recorded with respect to the impact of the Tax Cuts and Jobs Act of 2017, partially offset by an income tax impact related to entity restructuring and recapitalization efforts.  Also favorably impacting the third quarter of 2018 was a decrease in fair value of certain contingent consideration liabilities by $1.4 million ($2.2 million after tax), or $0.01 per diluted share. Partially offsetting these favorable impacts were acquisition and integration costs of $6.9 million ($5.1 million net of tax), or $0.03 per diluted share.

RECENT HIGHLIGHTS

• Selected for PacifiCorp's Aeolus - Jim Bridger Transmission Project - In October 2018, Quanta was selected by PacifiCorp to provide engineering, procurement and construction solutions for the Aeolus - Jim Bridger Transmission Line Project. This new high-voltage electric transmission project consists of approximately 138 miles of single circuit 500-kilovolt (kV) transmission line and approximately five miles of single circuit 345 kV transmission line that connects three substations in Wyoming. Quanta will include the project in its fourth quarter 2018 remaining performance obligations and backlog and expects to begin engineering and procurement activities for the project by year end, with construction starting in the spring of 2019. Quanta expects to complete the project in late 2020.
• Signed Five-Year Transmission Alliance Agreement - In September 2018, Quanta signed a five-year, sole-source transmission alliance agreement with a municipal utility that provides electricity and water services to customers and communities throughout Texas. Under the alliance agreement, which has a value of up to $400 million, Quanta will provide transmission construction and maintenance services across the customer's entire portfolio of transmission projects in Texas. Quanta believes its long work history, industry-leading safety performance and quality of service over a twenty-year relationship with the customer contributed to this award. Quanta has included the estimated revenues under this alliance agreement in its third quarter 2018 backlog.
• Industrial Services Operations Awarded Two Large Contracts - During the third quarter of 2018, Quanta was awarded, through its Stronghold operating unit, two large industrial services projects with an aggregate contract value in excess of $100 million. The awards include the largest refinery turnaround project in company history, which is to be completed for a large global energy company, and a facilities services project associated with the storage and transportation of refined products, including civil work, tank construction and mechanical services.
• Selected by TransCanada for North Montney Mainline Project in Canada - In August 2018, Quanta was selected by NOVA Gas Transmission Ltd., a TransCanada company, for spread three of the North Montney Mainline Project. Quanta's scope of work will be executed utilizing one mainline spread and includes the construction and installation of approximately 39 miles (62 kilometers) of new 42-inch diameter natural gas mainline pipe in Fort St. John, British Columbia. Quanta's construction began in the third quarter of 2018 and is anticipated to achieve substantial completion in the first half of 2019. This project is reflected in Quanta's third quarter 2018 remaining performance obligations and backlog.
• Repurchased Stock - During the third quarter of 2018, Quanta repurchased $23.8 million of its outstanding common stock in the open market, acquiring 0.7 million shares, and subsequent to the end of the third quarter, Quanta repurchased an additional $86.3 million of its outstanding common stock in the open market, acquiring 2.7 million shares. With these repurchases, Quanta has acquired a total of 9.0 million shares of its common stock for $303.9 million during 2018 and completed its prior $300 million stock repurchase program.
• Authorized New $500 Million Stock Repurchase Program - In September 2018, Quanta's board of directors, in support of management's request, authorized the company to repurchase, from time to time through June 30, 2021, up to $500 million in shares of its outstanding common stock under a new stock repurchase program. As of November 1, 2018, and taking into account the repurchases above, $446.1 million remains available under this stock repurchase program.
• Amended Credit Facility - In October 2018, in order to increase Quanta's liquidity and financial flexibility with favorable rates and terms, Quanta entered into an amendment to its senior secured credit facility that, among other things, increased its revolving credit facility by $175 million to $1.985 billion and provided for a new $600.0 million term loan facility. Upon closing, Quanta borrowed the full amount of the term loan facility and used the proceeds to repay outstanding borrowings under the revolving credit facility. Both the revolving credit facility and the term loan facility mature on October 31, 2022.

RESULTS FOR THE NINE MONTHS ENDED SEPTEMBER 30, 2018 AND 2017
Revenues in the first nine months of 2018 were $8.06 billion, compared to revenues of $6.99 billion in the first nine months of 2017, and net income attributable to common stock was $236.5 million in the first nine months of 2018, or $1.52 per diluted share, compared to net income attributable to common stock of $201.4 million, or $1.28 per diluted share, in the first nine months of 2017. Adjusted diluted earnings per share attributable to common stock (a non-GAAP measure) was $1.85 for the first nine months of 2018 compared to $1.52 for the first nine months of 2017.

Quanta completed four acquisitions during the first nine months of 2018 and three acquisitions during the full-year 2017. Therefore, Quanta's results for the three and nine months ended September 30, 2018 include the results of the acquired businesses from the acquisition dates and are compared to the historical results for the three and nine months ended September 30, 2017. For further information on the items that impacted comparability in 2018 and 2017, see the footnotes to the Supplemental Segment Data table and the non-GAAP reconciliations of adjusted EBITDA and adjusted diluted earnings per share attributable to common stock below.

OUTLOOK
The long-term outlook for Quanta's business is positive. However, weather, regulatory, permitting, project timing, execution challenges and other factors have impacted the company's historical results, and may impact Quanta's future financial results. Therefore, Quanta's financial outlook for revenues, margins and earnings reflects management's effort to properly align these uncertainties with the backlog the company is executing on and the opportunities expected to materialize during 2018. The following forward-looking statements are based on current expectations, and actual results may differ materially.

Prior to the company's conference call, management will post a summary of updated 2018 guidance expectations with additional commentary in the "Investors & Media" section of Quanta's website at http://investors.quantaservices.com. Quanta now expects revenues to range between $10.95 billion and $11.05 billion, net income attributable to common stock to range between $347.6 million and $363.1 million, and diluted earnings per share attributable to common stock to be between $2.25 and $2.35. Quanta expects adjusted diluted earnings per share attributable to common stock (a non-GAAP measure) to range between $2.70 and $2.80, EBITDA (a non-GAAP measure) to now be between $813.0 million and $838.2 million, and adjusted EBITDA (a non-GAAP measure) to now be between $878.6 million and $903.8 million. See the tables below for reconciliations of estimated adjusted diluted earnings per share attributable to common stock to estimated GAAP diluted earnings per share attributable to common stock for the full-year 2018 and estimated EBITDA and estimated adjusted EBITDA to estimated GAAP net income attributable to common stock for the full-year 2018.

NON-GAAP FINANCIAL MEASURES
The non-GAAP measures in this press release are provided to enable investors, analysts and management to evaluate Quanta's performance excluding the effects of certain items that management believes impact the comparability of operating results between reporting periods. In addition, management believes these measures are useful in comparing Quanta's operating results with those of its competitors. These measures should be used in addition to, and not in lieu of, results prepared in conformity with United States generally accepted accounting principles (GAAP).

Performance Obligations and Backlog (a non-GAAP measure)

A performance obligation is a promise in a contract with a customer to transfer a distinct good or service. 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 for fixed price contracts not yet completed or for which work has not yet begun. For purposes of calculating remaining performance obligations, Quanta includes all 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 occur and revenues from change orders to the extent management believes additional contract revenues will be earned and are deemed probable of collection.

Quanta has also historically disclosed its backlog, and while backlog is not a defined term under United States generally accepted accounting principles (GAAP), it is a common measurement used in Quanta's industry. Quanta also believes this non-GAAP measure enables it to more effectively forecast its future results and better identify future operating trends that may not otherwise be apparent. Quanta's remaining performance obligations, as described above, are a component of Quanta's 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 (a non-GAAP measure) as of September 30, 2018, along with estimates of amounts expected to be realized within 12 months of September 30, 2018:

The following table presents Quanta's backlog by reportable segment as of September 30, 2018, December 31, 2017 and September 30, 2017, along with an estimate of the backlog amounts expected to be realized within 12 months of each balance sheet date:

For the Three and Nine Months Ended

(In thousands, except per share information)
(Unaudited)

The non-GAAP measure of adjusted diluted earnings per share attributable to common stock, when used in connection with diluted earnings per share attributable to common stock, is 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 enables it to more effectively evaluate Quanta's operations period over period and better identify operating trends that may not otherwise be apparent. As to certain of the items below, (i) amortization of intangible assets is impacted by Quanta's acquisition activity, and therefore can vary from period to period; (ii) non-cash stock-based compensation expense may vary due to acquisition activity, changes in the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted; (iii) acquisition and integration costs vary period to period depending on the level of Quanta's ongoing acquisition activity, (iv) severance and restructuring costs and asset impairment charges can vary from period to period depending on economic and other factors; (v) changes in fair value of contingent consideration liabilities vary from period to period depending on financial performance of certain acquired businesses; (vi) adjustments related to the Tax Cuts and Jobs Act of 2017 could occur throughout 2018 and vary period to period depending on further analysis and as more information becomes available; (vii) income tax contingency releases vary period to period depending on the level of reserves for uncertain tax positions and the expiration dates under various federal and state tax statute of limitations periods; and (viii) items related to entity restructuring and recapitalization efforts are not regularly recurring items. Because adjusted diluted earnings per share attributable to common stock, as defined, excludes some, but not all, items that affect net income attributable to common stock, adjusted diluted earnings per share attributable to common stock as presented in this press release 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.

For the Three and Nine Months Ended
September 30, 2018 and 2017
(Unaudited)

(a) The amount for the nine months ended September 30, 2018 reflects the elimination of severance and restructuring costs related to the closure of certain operations within Quanta's Oil and Gas Infrastructure Services segment.

(b) The amount for the nine months ended September 30, 2018 reflects the elimination of a charge associated with the exchange of a construction barge for an industrial property. The amount for the nine months ended September 30, 2017 reflects the elimination of a previous charge associated with a planned sale of the construction barge that was not consummated. Although this charge was disclosed in connection with the 2017 second quarter results, it was not reflected as an adjustment to GAAP reported results. It is now reflected as an adjustment to be comparable to the current period presentation. These charges relate to Quanta's Oil and Gas Infrastructure Services segment.

(c) The amount for the three and nine months ended September 30, 2018 reflects the elimination of the adjustment to our provisional estimate recorded related to the impact of the Tax Cuts and Jobs Act of 2017. The adjustment primarily relates to refinements of Quanta's prior estimates and assumptions in connection with filing its 2017 income tax returns.

(d) The amounts reflect releases of tax contingencies upon expiration of certain tax statute of limitations periods during the third quarters of 2018 and 2017.

(e) The amount for the three and nine months ended September 30, 2018 reflects the elimination of income tax impacts related to entity restructuring and recapitalization efforts.

(f) The income tax impact of adjustments that are subject to tax is determined using the incremental statutory tax rates of the jurisdictions to which each adjustment relates for the respective periods.

(g) Both diluted and adjusted diluted earnings per share attributable to common stock for the nine months ended September 30, 2017 were impacted by attorneys' fees and related expenses of approximately $4.2 million ($2.7 million net of tax), or $0.02 per share, associated with certain litigation that was resolved in the first quarter of 2017. Additionally, both diluted and adjusted diluted earnings per share attributable to common stock for the nine months ended September 30, 2017 were impacted by a $2.4 million charitable contribution made in connection with the formation and funding of a non-profit line school.

EBITA, EBITDA and Adjusted EBITDA
For the Three and Nine Months Ended
September 30, 2018 and 2017
(In thousands)
(Unaudited)

The following table presents the non-GAAP financial measures of EBITA, EBITDA and Adjusted EBITDA for the three and nine months ended September 30, 2018 and 2017, which, when used in connection with net income attributable to common stock, is intended to provide useful information to investors and analysts as they evaluate Quanta's performance. EBITA is defined as earnings before interest, taxes, amortization and equity in (earnings) losses of unconsolidated affiliates. EBITDA is defined as earnings before interest, taxes, depreciation, amortization and equity in (earnings) losses of unconsolidated affiliates, and Adjusted EBITDA is defined as earnings before interest, taxes, depreciation, amortization, equity in (earnings) losses of unconsolidated affiliates and certain other items as described below. These measures should not be considered as an alternative to net income attributable to common stock or other 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 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) amortization of intangible assets is impacted by Quanta's acquisition activity, and therefore can vary from period to period; (ii) equity in (earnings) losses of unconsolidated affiliates can vary from period to period depending on the activity and financial performance of unconsolidated affiliates, including deferral of a portion of the earnings on a large construction contract performed by Quanta for an affiliate in which Quanta has an equity interest; (iii) non-cash stock-based compensation expense may vary due to acquisition activity, changes in the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted; (iv) acquisition and integration costs vary period to period depending on the level of Quanta's ongoing acquisition activity; (v) severance and restructuring costs and asset impairment charges can vary from period to period depending on economic and other factors; and (vi) changes in fair value of contingent consideration liabilities vary from period to period depending on financial performance of certain acquired businesses. Because EBITA, 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.

Free (Negative Free) Cash Flow (a non-GAAP measure):

The non-GAAP measure of free (negative free) cash flow, when used in connection with net cash provided by (used in) operating activities, 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 (negative free) cash flow is defined as net cash provided by (used in) operating activities less net capital expenditures. Net capital expenditures is defined as capital expenditures less proceeds from sale of property and equipment and proceeds from insurance settlements related to property and equipment. Management believes that free (negative free) cash flow provides useful information to Quanta's investors because free (negative 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 free (negative free) cash flow for capital allocation purposes as it is viewed as a measure of cash available to pay debt, acquire businesses, repurchase common stock and transact other investing and financing activities. The most comparable GAAP financial measure, net cash provided by (used in) operating activities, and information reconciling the GAAP and non-GAAP financial measures, are included below.

Other Non-GAAP Definitions:

Definition of Days Sales Outstanding:
Days Sales Outstanding 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, and divided by average revenues per day during the quarter.

Definition of Total Liquidity:
Total liquidity includes Quanta's cash and cash equivalents and availability under Quanta's senior secured credit facility.

As to certain of the items below, (i) amortization of intangible assets is impacted by Quanta's acquisition activity, and therefore can vary from period to period; (ii) non-cash stock-based compensation expense may vary due to acquisition activity, changes in the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted; (iii) acquisition and integration costs vary period to period depending on the level of Quanta's ongoing acquisition activity; (iv) severance and restructuring costs and asset impairment charges can vary from period to period depending on economic and other factors; (v) changes in fair value of contingent consideration liabilities vary from period to period depending on financial performance of certain acquired businesses; (vi) adjustments related to the Tax Cuts and Jobs Act of 2017 could occur throughout 2018 and vary period to period depending on further analysis and as more information becomes available; (vii) income tax contingency releases vary period to period depending on the level of reserves for uncertain tax positions and the expiration dates under various federal and state tax statute of limitations periods; and (viii) items related to entity restructuring and recapitalization efforts are not regularly recurring items. Because adjusted diluted earnings per share attributable to common stock, as defined, excludes some, but not all, items that affect net income attributable to common stock, adjusted diluted earnings per share attributable to common stock as presented in this press release 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.

Reconciliation of Non-GAAP Financial Measures
Estimated EBITA, EBITDA and Adjusted EBITDA
For the Full Year 2018
(In thousands)
(Unaudited)

The following table presents the non-GAAP financial measures of estimated EBITA, EBITDA and Adjusted EBITDA, which, when used in connection with estimated net income attributable to common stock, is intended to provide useful information to investors and analysts as they evaluate Quanta's performance. EBITA is defined as earnings before interest, taxes, amortization and equity in (earnings) losses of unconsolidated affiliates. EBITDA is defined as earnings before interest, taxes, depreciation, amortization and equity in (earnings) losses of unconsolidated affiliates, and Adjusted EBITDA is defined as earnings before interest, taxes, depreciation, amortization, equity in (earnings) losses of unconsolidated affiliates and certain other items as described below. These measures should not be considered as an alternative to net income attributable to common stock or other 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 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) amortization of intangible assets is impacted by Quanta's acquisition activity, and therefore can vary from period to period; (ii) equity in (earnings) losses of unconsolidated affiliates can vary from period to period depending on the activity and financial performance of unconsolidated affiliates, including deferral of a portion of the earnings on a large construction contract performed by Quanta for an affiliate in which Quanta has an equity interest; (iii) non-cash stock-based compensation expense may vary due to acquisition activity, changes in the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted; (iv) acquisition and integration costs vary period to period depending on the level of Quanta's ongoing acquisition activity; (v) severance and restructuring costs and asset impairment charges can vary from period to period depending on economic and other factors; and (vi) changes in fair value of contingent consideration liabilities vary from period to period depending on financial performance of certain acquired businesses. Because EBITA, 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.
