Quanta Services Reports First Quarter 2019 Results

HOUSTON, May 2, 2019 /PRNewswire/ -- Quanta Services, Inc. PWR today announced results for the three months ended March 31, 2019. Revenues in the first quarter of 2019 were $2.81 billion, compared to revenues of $2.42 billion in the first quarter of 2018, and net income attributable to common stock was $120.5 million, or $0.82 per diluted share, in the first quarter of 2019, compared to net income attributable to common stock of $37.6 million, or $0.24 per diluted share, in the first quarter of 2018. Adjusted diluted earnings per share attributable to common stock (a non-GAAP measure) was $0.96 for the first quarter of 2019 compared to $0.39 for the first quarter of 2018. Included in GAAP and adjusted diluted earnings per share for the first quarter of 2019 is the recognition of $60.3 million ($43.9 million after-tax), or $0.30 per diluted share, of earnings related to the accounting treatment of previously deferred earnings on Quanta's Fort McMurray West electric transmission project.

"Quanta is off to a solid start to the year with record first quarter results. Spending by electric utilities on grid modernization and system hardening and by gas utilities on distribution system modernization and safety programs is driving strong demand for our services. These dynamics were meaningful contributors to our 16 percent quarter over quarter revenue growth and are expected to be meaningful drivers of our base business growth going forward," said Duke Austin, President and Chief Executive Officer of Quanta Services. "As a result of our solid first quarter results, increased visibility for our electric power services and confidence in our ability to safely execute, we are increasing our full-year financial expectations. Also during the first quarter, through a successful collaboration with our partner ATCO and driven by world-class execution by our employees, we completed and energized the Fort McMurray West 500-kV Transmission Project three months ahead of schedule, on budget and with an impeccable safety record."

RECENT HIGHLIGHTS

• Progress on PG&E Pre-Petition Receivables - In April 2019, the United States Bankruptcy Court for the Northern District of California approved Pacific Gas and Electric's (PG&E) assumption of two substantial contracts with Quanta, which authorizes PG&E to pay approximately $116 million of pre-petition receivables due under those contracts. Quanta expects to receive payment of these amounts in the near term and believes this development underscores the collaborative nature of its customer relationships and the value customers place on Quanta's ability to strategically support them. Quanta looks forward to continuing its long-standing relationship with PG&E.
• Completed Major Electric Transmission Project - During the first quarter of 2019, Quanta, along with its partner ATCO, completed construction and energized the Fort McMurray West 500-kV Transmission Project in Alberta, Canada. With a total project value of CAD 1.6 billion, this was the largest project ever completed by Quanta and included engineering, procurement and construction services for the 508-km transmission line project. The project was financed through the largest public-private partnership bond in Canadian history, was the longest 500-kV AC transmission line built in Canada's history and was ranked among the top 40 infrastructure projects in Canada in 2018.

Quanta completed one acquisition during the first three months of 2019 and four acquisitions during the full-year 2018. Therefore, Quanta's results for the three months ended March 31, 2019 include the results of the acquired businesses from their respective acquisition dates. For further information on the items that impacted comparability of 2019 and 2018, 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 2019. 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 2019 guidance expectations with additional commentary in the "Investors & Media" section of Quanta's website at http://investors.quantaservices.com.

As a result of solid first quarter results and increased visibility for electric power services, Quanta has increased its full-year financial expectations. Quanta expects revenues to range between $11.2 billion and $11.6 billion, net income attributable to common stock to range between $421 million and $488 million, and diluted earnings per share attributable to common stock to range between $2.86 and $3.32. Quanta expects adjusted diluted earnings per share attributable to common stock (a non-GAAP measure) to range between $3.40 and $3.86. Included in Quanta's GAAP and adjusted diluted earnings per share expectations is the recognition of $0.30 per diluted share of earnings related to the accounting treatment of previously deferred earnings on the Fort McMurray West electric transmission project. The project was completed and placed in commercial operation in the first quarter of 2019, which resulted in the recognition of prior period deferred earnings that is reflected in other income (expense), net in the company's statements of operations. EBITDA (a non-GAAP measure) is expected to range between $841 million and $942 million and adjusted EBITDA (a non-GAAP measure) is expected to range between $905 million and $1.0 billion. 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 2019 and estimated EBITDA and estimated adjusted EBITDA to estimated GAAP net income attributable to common stock for the full-year 2019.

IMPACT OF NEW LEASE ACCOUNTING IMPLEMENTATION
Effective January 1, 2019, Quanta adopted the provisions of the new lease accounting standard (ASC 842). The adoption of ASC 842 resulted in the recognition of operating lease right-of-use assets and operating lease liabilities. As of March 31, 2019, operating lease right-of-use assets and operating lease liabilities were $285.8 million. These operating lease assets and liabilities exclude certain short-term leases that, pursuant to ASC 842, are not required to be recorded on Quanta's balance sheet. Quanta does not expect a material impact to its operating results or borrowing capacity as a result of ASC 842.

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 generally accepted accounting principles in the United States (GAAP).

Remaining Performance Obligations and Backlog (a non-GAAP 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 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.

While backlog is not a defined term under GAAP, it is a common measurement used in Quanta's industry. Quanta 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 (a non-GAAP measure) by reportable segment along with estimates of amounts expected to be realized within 12 months:

The following table presents the non-GAAP measure of adjusted diluted earnings per share attributable to common stock for the three months ended March 31, 2019 and 2018, which, 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) 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; (ii) amortization of intangible assets is impacted by Quanta's acquisition activity, and therefore can vary from period to period; (iii) acquisition and integration costs vary period to period depending on the level of Quanta's ongoing acquisition activity, (iv) changes in fair value of contingent consideration liabilities vary from period to period depending on the forecasted performance of certain acquired businesses; and (v) tax settlements and adjustments to related indemnification assets vary from period to period depending on the status and resolution of pending matters. 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.

The following table presents the non-GAAP financial measures of EBITDA and Adjusted EBITDA for the three months ended March 31, 2019 and 2018, which, when used in connection with net income attributable to common stock, are intended to provide useful information to investors and analysts as they evaluate Quanta's performance. EBITDA is defined as earnings before interest, taxes, depreciation, amortization and equity in (earnings) losses of unconsolidated affiliates, 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 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) 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 and subsequent recognition upon completion of construction of earnings on contracts performed for entities in which Quanta has an equity interest; (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) changes in fair value of contingent consideration liabilities vary from period to period depending on the forecasted performance of certain acquired businesses; and (v) tax settlements and adjustments to related indemnification assets vary from period to period depending on the status and resolution of pending matters.

Reconciliation of Free (Negative Free) Cash Flow:
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 the sale of property and equipment and 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 this measure for capital allocation purposes as it is viewed as a measure of cash available to pay debt, acquire businesses, repurchase common stock, declare and pay dividends 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:

Days Sales Outstanding:
Days Sales Outstanding is calculated by using the sum of current accounts receivable, net of allowance (which includes current retainage and unbilled balances), 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 secured credit facility.
