Management Comments

Bill Koertner, MYR’s President and CEO, said, “We are pleased to report second quarter revenue growth compared to the same quarter last year on both the transmission and distribution sides of our T&D business as well as our C&I business. Gross profit and EPS were also higher in the second quarter compared to last year, in spite of a continued sluggish economy. Margins remain under pressure with our distribution work and in our C&I business. We have had substantial growth in our backlog from $199.6 million at June 30, 2010 to $716.9 million at June 30, 2011 primarily as a result of several large transmission project awards over the last nine months. Bidding activity for large transmission projects should continue to be strong over the next few years, albeit perhaps not at the intense pace experienced over the last nine months. Our recently awarded large transmission projects are in their early stages of construction. Revenue and gross profit recognition on these projects will likely start slow and accelerate over time until project construction reaches full stride. 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 large projects that strategically fit our parameters and core competencies.”

Second-Quarter Results

MYR reported second-quarter 2011 revenues of $185.3 million, an increase of $45.0 million, or 32.1 percent, compared to the second quarter of 2010. Specifically, the Transmission and Distribution (T&D) segment reported revenues of $139.7 million, an increase of 29.6 percent over the second quarter of 2010. The increase in revenues in the T&D segment was primarily the result of an increase in revenues from several large (over $10.0 million in contract value) and many small (under $3.0 million in contract value) transmission projects, as well as an increase in distribution revenues from a few traditional utility customers and several small projects outside of our core utility distribution work. These non-core distribution projects were substantially completed in the second quarter. The Commercial and Industrial (C&I) segment reported revenues of $45.6 million, an increase of $13.1 million, or 40.4 percent, over the second quarter of 2010, primarily due to one

large project that had significant revenue related to subcontractor work and material procurement in the quarter.

Consolidated gross profit increased to $19.5 million for the second quarter of 2011 from $16.7 million for the second quarter of 2010. As a percentage of overall revenues, gross margin decreased to 10.5 percent for the second quarter of 2011 from 11.9 percent for the same period of 2010. The decrease in gross profit as a percentage of revenues was mainly attributable to an overall decrease in contract margins on a few medium-sized C&I projects (between $3.0 million and $10.0 million in contract value) of approximately $2.0 million which was due to pricing pressures over the past year, as well as a margin adjustment of approximately $0.7 million for cost inefficiencies and higher than expected material costs on one project.

Selling, general and administrative expenses increased approximately $2.7 million, or 24.0 percent, to $13.7 million for the second quarter of 2011 from $11.0 million for the second quarter of 2010. The increase was primarily due to an increase in group medical insurance cost, an increase in the number of support personnel and an overall increase in other employee related compensation and benefit costs in the second quarter of 2011.

For the second quarter of 2011, net income was $3.7 million, or $0.18 per diluted share, compared to $3.4 million, or $0.16 per diluted share, for the same period of 2010. Second-quarter 2011 EBITDA was $10.6 million, or 5.7 percent of revenues, compared to $9.7 million, or 6.9 percent of revenues, in the second quarter of 2010. The decrease in EBITDA as a percentage of revenues was mainly due to the decrease in gross profit margin discussed above.

First-Half Results

MYR reported revenues of $335.6 million for the first half of 2011, an increase of $46.4 million, or 16.1 percent, compared with the first half of 2010. The T&D segment reported revenues of $257.7 million in the first half of 2011, an increase of 22.4 percent over 2010. The increase in revenues was primarily the result of an increase in revenues from a few large T&D contracts and many small transmission projects, offset by a decrease in revenues from several small distribution contracts. The C&I segment reported first half 2011 revenues of $77.9 million, a decrease of 0.8 percent from 2010.

Consolidated gross profit increased to $41.1 million for the first half of 2011 from $31.9 million for the first half of 2010. As a percentage of overall revenues, gross margin increased to 12.2 percent for the first half of 2011 from 11.0 percent for first half 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 of approximately $5.4 million as a result of increased productivity levels, cost efficiencies, added work and effective contract management. These large projects, which generated above-normal margins in the six months ended June 30, 2011, were substantially completed in the second quarter. Gross profit also increased by approximately $1.5 million on T&D projects with contract values less than $10 million. The increases in gross profit as a percentage of revenues in the T&D segment were partially offset by a decrease of $3.0 million in gross profit on C&I projects with contract values of less than $10.0 million. This decrease was mostly the result of lower overall margins due to pricing pressures over the past year, as well as a margin adjustment in the second quarter of approximately $0.7 million on one project due to cost inefficiencies and higher than expected material costs.

Selling, general and administrative expenses increased to $27.7 million for the first half of 2011 from $21.6 million for the first half of 2010. The increase was primarily due to increases in group medical insurance cost, the number of support personnel and other employee related compensation and benefit costs in the first half of 2011, coupled with the first quarter 2010 one-time reversal of a $1.6 million severance liability as a result of amending the employment agreements of our six named executive officers, which had the effect of decreasing selling, general and administrative expenses in that period. As a percentage of revenues, these expenses increased to 8.2 percent for the first half of 2011 from 7.5 percent for the first half of 2010.

For the first half of 2011, net income was $8.2 million, or $0.39 per diluted share, compared to $6.1 million, or $0.30 per diluted share, for the same period of 2010. EBITDA for the first half of 2011 was $22.6 million, or 6.7 percent of revenues, compared to $18.4 million, or 6.4 percent of revenues, for the first half of 2010. The increase in EBITDA as a percentage of revenues was mainly due to an increase in depreciation expense coupled with an increase in gross profit margins.

Backlog

As of June 30, 2011, MYR’s backlog was approximately $716.9 million, consisting of $646.1 million in the T&D segment and $70.8 million in the C&I segment. Total backlog increased $517.3 million, or 259.1 percent, from $199.6 million reported at June 30, 2010. The increase was primarily related to several large contracts that were awarded in the Company’s T&D segment at the end of 2010 and early in 2011.

Total backlog at June 30, 2011 was $113.0 million higher as compared to the $603.9 million backlog reported at March 31, 2011. T&D backlog increased $122.4 million, or 23.4 percent, while C&I backlog decreased $9.4 million, or 11.7 percent, compared to backlog at March 31, 2011.

MYR’s method of calculating backlog may differ from methods used by other companies. The increase in backlog from the second quarter of 2010 was primarily related to several large contracts that were awarded within the T&D segment late in 2010 and in the first half of 2011. As publicly announced, prior to the end of the second quarter, we were one of the contractors selected to perform work on the CAPX2020 project, and we executed a master agreement with Electric Transmission Texas for Competitive Renewable Energy Zone work. However, these projects were not included in backlog as of June 30, 2011 because the scope of work had not been defined or agreed upon, and therefore those contracts did not meet our backlog criteria.

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 June 30, 2011, MYR had cash and cash equivalents of $35.4 million and total long-term debt of $10.0 million under a term loan. As of June 30, 2011, MYR also had a $75 million revolving credit facility, which had a $15.0 million letter of credit outstanding against the total credit available. 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 in the United States (GAAP). 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 included performance conditions that were not met.

(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.
