Management Comments

Bill Koertner, MYR’s president and CEO, said, “We have benefited in the last couple quarters from the favorable close out of some of our major projects which has improved our margins. These projects will be substantially completed by the end of the second quarter. We expect to replace these revenues in the second half of the year as we ramp up construction on some of our recent awards, however, the margins on these new contracts may not match those of the work being completed.  We recently announced new major contracts in Virginia and Texas. These projects, along with awards announced in the fourth quarter last year, will contribute to our workload over the next several years. We are very appreciative of the confidence our customers have shown in selecting us for these large transmission projects. Our teams are focused on executing these new projects with some of the best people and equipment in the business, and we continue to bid additional large projects and related upgrades for the U.S. transmission grid. We are beginning to see some improvements in the overall economy, however, our utility distribution and C&I businesses remain soft.”

First-Quarter Results

MYR reported first-quarter 2011 revenues of $150.3 million, an increase of $1.4 million, or 0.9 percent, compared to the first quarter of 2010. Specifically, the Transmission and Distribution (T&D) segment reported revenues of $118.0 million, an increase of $15.2 million, or 14.8 percent, over the first quarter of 2010. The Commercial and Industrial (C&I) segment reported revenues of $32.3 million, a decrease of $13.8 million, or 29.9 percent, over the first quarter of 2010. The majority of the increase in revenues was the result of an increase in revenues from several medium-sized T&D projects (between $3.0 million and $10.0 million in contract value) which was substantially offset by a decrease in revenues from a few large C&I projects (greater than $10.0 million in contract value).

Consolidated gross profit increased to $21.6 million, or 14.4 percent of revenues in the first quarter of 2011, compared to $15.2 million, or 10.2 percent of revenues in the first quarter of 2010. The increase in gross profit as a percentage of revenues was mainly attributable to an overall increase in contract margins on a few large transmission projects (greater than $10.0 million in contract value) of approximately $5.8 million as a result of increased productivity levels, cost efficiencies, added work and effective project management.  These large projects, which generated above-normal

margins in the current period, will be substantially completed in the second quarter of 2011.  Gross profit also increased by approximately $1.2 million on T&D projects with contract values less than $10 million, which was mostly offset by a decrease in gross profit on C&I projects with contract values less than $10 million.

Selling, general and administrative expenses (SG&A) increased approximately $3.4 million, or 32.1 percent, to $14.0 million in the first quarter of 2011 compared to $10.6 million in the first quarter of 2010. The increase was primarily due to an overall increase in profit sharing and other employee-related compensation and benefit costs in the first quarter of 2011 coupled with the first quarter 2010 one-time elimination of a $1.6 million severance liability as a result of amending the employment agreements of our six executive officers. As a percentage of revenues, these expenses increased to 9.3 percent for the three months ended March 31, 2011 from 7.1 percent for the three months ended March 31, 2010.

For the first quarter of 2011, net income was $4.5 million, or $0.21 per diluted share, compared to $2.8 million, or $0.13 per diluted share, for the same period of 2010. First-quarter 2011 EBITDA was $11.9 million, or 7.9 percent of revenues, compared to $8.7 million, or 5.8 percent of revenues, in the first quarter of 2010. The increase in EBITDA as a percentage of revenues was mainly due to an increase in gross profit margin, as discussed above.

Backlog

As of March 31, 2011, MYR’s backlog was approximately $603.9 million, consisting of $523.7 million in the T&D segment and $80.2 million in the C&I segment. Total backlog increased $404.4 million, or 202.7 percent, from the $199.5 million reported at March 31, 2010. The increase in backlog comparing the first quarter of 2011 to the first quarter of 2010 was primarily related to several large contracts that were awarded in the Company’s T&D segment late in 2010 and in the first quarter of 2011.

Total backlog at March 31, 2011 was $83.0 million higher than the $520.9 million backlog reported at December 31, 2010. T&D backlog increased $94.7 million, or 22.1 percent, while C&I backlog decreased $11.7 million, or 12.8 percent, compared to backlog at December 31, 2010.

MYR’s method of calculating backlog may differ from methods used by other companies. The timing of contract awards and the duration of large projects can significantly affect MYR’s backlog at any point in time and may not accurately represent the revenues that MYR expects to realize during any period, therefore, it should not be viewed or relied upon as a stand-alone indicator of future results.

Balance Sheet

As of March 31, 2011, MYR had cash and cash equivalents of $44.7 million and total long-term debt of $10 million under a term loan. In the first quarter of 2011, MYR prepaid $20 million of its outstanding long-term debt reducing the balance to $10 million. As of March 31, 2011, MYR also had a $75 million revolving credit facility, of which $15 million was used in a letter of credit outstanding, leaving $60 million of available credit. MYR’s long-term credit agreement, which encompasses the term loan and the revolving credit facility, expires on August 31, 2012.

Non-GAAP Financial Measures

To assist investors’ understanding of the Company’s financial results, MYR has provided EBITDA in this press release. EBITDA is a measure not recognized by generally accepted accounting principles (GAAP) in the United States. Management believes this information is useful to investors in understanding results of operations because it illustrates the impact that interest, taxes, depreciation and amortization had on MYR’s results. A reconciliation of EBITDA to its GAAP counterpart (net income) is provided at the end of this release.

(1)       The Company calculates net income per common share in accordance with ASC 260, Earnings Per Share. Basic earnings per share are calculated by dividing net income by the weighted average number of shares outstanding for the reporting period. Diluted earnings per share are computed similarly, except that it reflects the potential dilutive impact that would occur if dilutive securities were exercised into common shares. Potential common shares are not included in the denominator of the diluted earnings per share calculation when inclusion of such shares would be anti-dilutive or performance conditions have not been met on performance awards.

(2)       EBITDA is not recognized under GAAP and does not purport to be an alternative to net income as a measure of operating performance or to net cash flows provided by operating activities as a measure of liquidity.
