PowerSecure Reports Second Quarter Results

Strong Revenue Growth and Gross Margin Increase Drive Profit Gain, Backlog

Reaches Record $166 Million

Wake Forest, N.C. – August 6, 2012 – PowerSecure International, Inc. (Nasdaq: POWR) today reported its second quarter 2012 results, including strong second quarter revenues of $37.9 million, gross margin of 32.2 percent, diluted earnings per share (“E.P.S.”) from continuing operations of $0.09, and Non-GAAP E.P.S. from continuing operations of $0.03. This compares to second quarter 2011 revenues of $30.1 million, gross margin of 30.9%, diluted E.P.S. from continuing operations of $0.97, and Non-GAAP loss from continuing operations of ($0.03) per share. Non-GAAP per share amounts for both periods exclude income and gains related to the sale of the Company’s WaterSecure investment (see Non-GAAP discussion and reconciliation, below).

Sidney Hinton, CEO of PowerSecure, said, “We are having a terrific 2012. Each of our product and service areas is showing strong growth, driving our profit increases, and our backlog is a record $166 million. Additionally, our gross margins increased 3.4 percentage points sequentially, and 1.3 percentage points over last year. We are in great position for the second half of 2012 and 2013.” Mr. Hinton continued, “We continue to be very focused on translating our top-line success to bottom-line E.P.S. results, and leveraging the incremental operating expenses we have invested in to drive our business forward. I am pleased to report that in our second quarter our operating expenses decreased 2.5 percentage points as a percentage of revenue.”

Each of the Company’s product and service lines have grown significantly in size and scale over the last several quarters, driven by an expansion of its utility partners, a growing customer base, and a growing portfolio of product offerings and service capabilities. Exhibit A illustrates the increased scale achieved in each of the Company’s product and service lines, comparing trailing twelve month revenue for the period ended June 30, 2012, which totaled $147.3 million, to the period ended June 30, 2011, which totaled $100.8 million, a 46% increase.

The Company’s strong second quarter 2012 year-over-year revenue growth of 26%, to $37.9 million, was driven by a 27% increase in Distributed Generation products and services, a 12% increase in Utility Infrastructure products and services, and a 51% increase in Energy Efficiency products, as shown below.

The Company’s second quarter 2012 gross margin as a percentage of revenue was 32.2% compared to 30.9% in the second quarter of 2011. The gross margin increase was driven by favorabilities in the mix of projects completed in 2012 compared to 2011, a higher percentage of revenues from the Company’s higher margin Distributed Generation and Energy Efficiency product areas, and higher revenues from the Company’s higher margin company-owned distributed generation recurring revenue projects.

Operating expenses for the second quarter of 2012 were $11.6 million compared to $10.0 million in the second quarter of 2011. As a percentage of revenue, operating expenses decreased 2.5 percentage points on a year-over-year basis. The Company’s operating expenses included $0.3 million of costs from its acquisition of a distributed solar energy company during the second quarter of 2012.

The Company’s capital resources continue to be strong, with $23.7 million in cash and zero drawn on its revolving credit facility at the end of the second quarter of 2012. The Company’s capital expenditures during the second quarter were $2.5 million in total, with $1.9 million of this capital invested to deploy systems to support PowerSecure-owned long-term recurring revenue Distributed Generation projects.

The Company announced that its revenue backlog stands at $166 million. This includes new business awards announced on July 24, 2012 and August 1, 2012. It also includes revenue from projects assumed in conjunction with its acquisition of a distributed solar energy company during the second quarter of 2012. The Company’s revenue backlog represents revenue expected to be recognized after June 30, 2012, for periods including the third quarter of 2012 onward. This backlog figure compares to the revenue backlog of $151 million announced in the Company’s first quarter earnings release issued on May 3, 2012, which represented revenue expected to be recognized after March 31, 2012. The Company’s $166 million revenue backlog and the estimated timing of revenue recognition are outlined below, including “project-based revenues” expected to be recognized as projects are completed, and “recurring revenues” expected to be recognized over the life of the underlying contracts:

Revenue Backlog expected to be recognized after June 30, 2012

Note: Anticipated revenue and estimated primary recognition periods are subject to risks and uncertanities as indicated in the Company’s safe harbor statement, below. Consistent with past practice, these figures are not intended to constitute the Company’s total revenue over the indicated time periods, as the Company has additional, regular on-going revenues. Examples of additional, regular recurring revenues include revenues from the engineering fees, and service revenue, among others. Numbers may not add due to rounding.

Orders in the Company’s revenue backlog are subject to delay, deferral, acceleration, resizing, or cancellation from time to time, and estimates are utilized in the determination of the backlog amounts. Given the irregular sales cycle of customer orders, and especially of large orders, the revenue backlog at any given time is not necessarily an accurate indication of our future revenues.

The Company’s results include gains on the June, 2011 sale of its WaterSecure investment recorded in both the second quarter of 2011 of $21.8 million, and the second quarter of 2012 of $1.4 million. The gain recorded during the second quarter of 2012 relates to $1.4 million of contingent sale proceeds that were released from escrow to the Company during that period. The Company’s results also include discontinued operations comprised of the Company’s former Southern Flow unit, which was sold during the first quarter of 2011 and for which a $5.6 million gain on sale was recorded in that period, and the Company’s discontinued PowerPackages unit, which was exited during the second half of 2011. The results of these discontinued operations were negligible during the second quarter of 2012. However, these discontinued operations negatively impacted the second quarter of 2011 by ($1.4) million of after-tax income, or ($0.07) of E.P.S. The Company’s acquisition of a solar distributed energy company during the second quarter of 2012 also negatively impacted E.P.S. by ($0.01) per share.

Non-GAAP Pro forma Financial Measures:

Our references to our second quarter 2012 and 2011 “Non-GAAP Pro forma” financial measures of net income from continuing operations, net income, net income attributable to PowerSecure International, Inc., diluted E.P.S. from continuing operations, diluted E.P.S. from discontinued operations, and diluted E.P.S. discussed and shown in this report constitute non-GAAP financial measures. They refer to our GAAP results, adjusted to show the results 1) without the after-tax income from our WaterSecure investment, including gains realized on its sale (identified in our financial statements as our unconsolidated affiliate), 2) without the after-tax results of our discontinued PowerPackages business.

We believe providing non-GAAP measures which show our pro forma results with these items adjusted is valuable and useful as it allows our management and our board of directors to measure, monitor and evaluate our operating performance with the same consistent financial context as the business was managed and evaluated from 2011 forward. Additionally, because our WaterSecure business was sold in June, 2011, and our PowerPackages business was discontinued in 2011, these pro forma measures provide baseline comparatives which are more comparable to our current and future results.

We believe these Non-GAAP Pro forma measures also provide meaningful information to investors in terms of enhancing their understanding of our 2012 operating performance and results, as they allow investors to more easily compare our financial performance on a consistent basis compared to 2011. These Non-GAAP Pro forma measures also correspond with the way we expect Wall Street analysts to compare our results. Our Non-GAAP Pro forma measures should be considered only as supplements to, and not as substitutes for or in isolation from, our other measures of financial information prepared in accordance with GAAP, such as GAAP revenue, operating income, net income from continuing operations, net income, net income attributable to PowerSecure International, Inc., diluted E.P.S. from continuing operations, diluted E.P.S. from discontinued operations, and diluted E.P.S.
