	(In thousands, except per share data)

The following table presents the non-GAAP financial measure of adjusted diluted earnings per share from continuing operations for the first quarter of 2015. The non-GAAP measure of adjusted diluted earnings per share from continuing operations is provided to enable investors to evaluate performance excluding the effects of items that management believes impact the comparability of operating results between periods. As to certain of the items below, (i) amortization of intangible assets is impacted by Quanta’s acquisition activity, which can cause these amounts to vary from period to period; (ii) non-cash stock-based compensation expense may vary due to acquisition activity, factors influencing the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted during the period and (iii) acquisition costs vary period to period depending on the level of Quanta’s acquisition activity ongoing during the period.

The following table presents the non-GAAP financial measure of adjusted diluted earnings per share from continuing operations for the four quarters of 2014, along with the corresponding year-to-date amounts for each period presented. The non-GAAP measure of adjusted diluted earnings per share from continuing operations is provided to enable investors to evaluate performance excluding the effects of items that management believes impact the comparability of operating results between periods. As to certain of the items below, (i) amortization of intangible assets is impacted by Quanta’s acquisition activity, which can cause these amounts to vary from period to period; (ii) non-cash stock-based compensation expense may vary due to acquisition activity, factors influencing the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted during the period, (iii) acquisition costs vary period to period depending on the level of Quanta’s acquisition activity ongoing during the period and (iv) tax contingency releases vary period to period depending on the level of reserves for uncertain tax positions and the expiration dates of various federal and state tax statutes of limitations. Additionally, the following items are not regularly occurring operational items: (i) the charge to provision for long-term contract receivable and (ii) the expense associated with the arbitration decision.

(c) These amounts reflect the elimination of tax benefits primarily associated with the expiration of various federal and state tax statute of limitations periods.

(d) These amounts are attributable to continuing operations.

(e) The sum of the individual quarterly earnings per share amounts may not equal year-to-date earnings per share as the computation for each quarterly period is based on the weighted average number of shares outstanding during that period.

The following table presents the non-GAAP financial measure of adjusted diluted earnings per share from continuing operations for the four quarters of 2013, along with the corresponding year-to-date amounts for each period presented. The non-GAAP measure of adjusted diluted earnings per share from continuing operations is provided to enable investors to evaluate performance excluding the effects of items that management believes impact the comparability of operating results between periods. As to certain of the items below, (i) amortization of intangible assets is impacted by Quanta’s acquisition activity, which can cause these amounts to vary from period to period; (ii) non-cash stock-based compensation expense may vary due to acquisition activity, factors influencing the estimated fair value of performance-based awards, forfeiture rates, accelerated vesting and amounts granted during the period, (iii) acquisition costs vary period to period depending on the level of Quanta’s acquisition activity ongoing during the period, and (iv) tax contingency releases vary period to period depending on the level of reserves for uncertain tax positions and the expiration dates of various federal and state tax statutes of limitations. Additionally, the gain on the sale of an equity ownership interest is not a regularly occurring operational item.

	Quanta Services, Inc. and Subsidiaries
	2015, 2014 and 2013 Backlog Recast for Discontinued Operations
	(In millions)
	(Unaudited)

Backlog is not a term recognized under United States GAAP; however, it is a common measurement used in Quanta’s industry. Quanta’s methodology for determining backlog may not be comparable to the methodologies used by other companies. Quanta’s backlog represents the amount of consolidated revenue that it expects to realize from future work under construction contracts, long-term maintenance contracts and master service agreements. These estimates include revenues from the remaining portion of firm orders not yet completed and on which work has not yet begun, as well as revenues from change orders, renewal options, and funded and unfunded portions of government contracts to the extent that they are reasonably expected to occur. For purposes of calculating backlog, Quanta includes 100% of estimated revenues attributable to consolidated joint ventures and variable interest entities.

The following table presents Quanta’s total backlog by reportable segment as of the end of the first quarter of 2015 and all four quarters of 2014 and 2013, along with an estimate of the backlog amounts expected to be realized within 12 months of each date (in millions):
