Wake Forest, N.C. – November 6, 2013 – PowerSecure International, Inc. (NYSE: POWR) today reported its third quarter 2013 results. Highlights include:

“We saw strong top and bottom line growth across our business in the 3^rd quarter as our robust organic growth was enhanced by our successful acquisitions, and we continue to execute in delivering best-in-class solutions and service to customers,” said Sidney Hinton, chief executive officer of PowerSecure.

“Our record revenues and further operating margin expansion highlight our execution and, combined with our strong revenue backlog of $240 million, provide us with confidence that PowerSecure is exceptionally positioned for continued success,” Hinton added.

Third Quarter 2013:

PowerSecure’s third quarter 2013 (3Q 2013) revenues of $81.5 million increased $37.3 million, or 84.3 percent, over revenues in the third quarter of 2012 (3Q 2012). This increase was driven by a 62.2 percent year-over-year (y-o-y) increase in revenues from distributed generation products, a 72.1 percent y-o-y increase in revenues from utility infrastructure products and services, and a 225 percent y-o-y increase in revenues from energy efficiency products and services.

In total, $24.5 million of the y-o-y revenue growth was organic growth from our existing operations, representing a 55 percent increase, and the remaining $12.7 million of the y-o-y revenue growth was related to our recently acquired Solais and ESCO operations (for which no revenues were recognized in the prior year period).

Gross margin as a percentage of revenue was 26.3 percent in 3Q 2013 compared to 31.4 percent in 3Q 2012. The y-o-y gross margin decrease was due to the growth of our utility infrastructure, solar, and ESCO revenues in 3Q 2013, which are generally our lowest gross margin product and service categories. In addition, we realized inefficiencies in our utility infrastructure unit related to the advanced deployment of crews in anticipation of being selected for a significant long-term revenue opportunity with a major new utility partner. We anticipate some continued inefficiencies from these excess crews to negatively impact our gross margins during the fourth quarter of 2013 and the first quarter of 2014. A separate press release announcing our selection for this opportunity was issued today in conjunction with this earnings release.

Non-GAAP financial measures for 3Q 2012 exclude a $1.5 million pre-tax charge related to a Restructuring and Cost Reduction Plan that was initiated during 3Q 2012, to position the company for enhanced operating margins in future periods (see non-GAAP discussion and reconciliation).

Operating expenses for 3Q 2013 as a percentage of our revenues were 19.0 percent, a decrease of 11.2 percentage points on a GAAP basis compared to 30.3 percent in 3Q 2012, and a decrease of 7.8 percentage points excluding the $1.5 million 3Q 2012 charge, as the company leveraged operating expenses against a greater level of revenues.

Operating expenses for 3Q 2013 were $15.5 million, compared to $13.4 million in 3Q 2012. Excluding the $1.5 million charge in 3Q 2012, operating expenses in 3Q 2012 were $11.8 million. The $3.7 million y-o-y increase in operating expenses consists primarily of $2.8 million of incremental operating expenses in 3Q 2013 related to our recent ESCO and Solais acquisitions. The remaining y-o-y increase in our operating expenses is primarily due to an increase in selling expenses related to our significantly higher revenues and backlog, depreciation from our investments in company-owned distributed generation systems and utility infrastructure equipment, and increases in personnel and equipment to drive and support our growth.

Operating margin as a percentage of revenue increased 6.2 percentage points to 7.3 percent in 3Q 2013 from 1.1 percent in 3Q 2012. Excluding the 3Q 2012 charge, operating margin increased 2.7 percentage points. The increase in operating margin was a result of the significant revenue growth achieved with substantially lower growth in operating expenses.

Our recent acquisitions have provided additional opportunities to restructure and realign our operations to increase operating margins in our energy efficiency product and service lines in particular, as well as other cost reduction opportunities. This includes manufacturing and sourcing synergies that our Solais acquisition is expected to bring to our existing LED lighting operations, and other cost reduction opportunities. In contemplation of these opportunities, we commenced developing plans to integrate and streamline the operations and product offerings within our energy efficiency product area primarily, and to a lesser extent other areas of the company. Our intention is to eliminate certain duplicative facilities, re-source certain of our energy efficiency inventory suppliers, reduce the number of energy efficiency product offerings, and reduce personnel levels. We currently expect that this restructuring will result in a total charge of between $4 million and $6 million during the fourth quarter 2013 and the first quarter of 2014. In addition, these actions may result in additional charges related to goodwill or intangible impairment, the amount of which, if any, is not determinable at this time.

Diluted GAAP earnings per share (EPS) from continuing operations increased to $0.17 in 3Q 2013, compared to $0.03 in 3Q 2012. Non-GAAP EPS from continuing operations increased to $0.17 in 3Q 2013, compared to $0.08 in 3Q 2012.

The company completed the third quarter of 2013 with $54.1 million in cash and cash equivalents, zero drawn on its $20 million revolving credit facility and $26.2 million of term debt outstanding.

The company’s capital expenditures during Q3 2013 were $0.9 million, with $0.6 million of this capital invested to deploy systems to support PowerSecure-owned long-term recurring revenue distributed generation projects, and the remaining $0.3 million primarily invested in the purchase of equipment for its growing utility infrastructure business.

The company’s revenue backlog stands at $240 million, as of the date of this release. This includes new business from awards announced on September 19, 2013 and October 2, 2013, and an additional $17 million of new business the company has been awarded since October 2, 2013. The company’s revenue backlog represents revenue expected to be recognized after September 30, 2013, for periods including the fourth quarter of 2013 onward.

This backlog figure compares to the revenue backlog of $245 million announced in the company’s second quarter 2013 earnings release issued on August 7, 2013, which represented revenue expected to be recognized after June 30, 2013, and $175 in revenue backlog announced in the company’s 3Q 2012 earnings release issued on November 7, 2012.

The company’s $240 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 September 30, 2013

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 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.

Non-GAAP Pro forma Financial Measures Discussion:

Our references to our third quarter 2012 “Non-GAAP Pro forma” financial measures of net income from continuing operations, net income, net income attributable to PowerSecure International, Inc., diluted EPS from continuing operations, diluted EPS from discontinued operations and diluted EPS discussed and shown in this report constitute non-GAAP financial measures. They refer to our GAAP results, adjusted to show the results without the restructuring and cost reduction charge of $1.5 million recorded in the third quarter of 2012.

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. 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 EPS from continuing operations, diluted EPS from discontinued operations, and diluted EPS.

References to our third quarter and year-to-date 2012 and 2013 Adjusted EBITDA, which we define as our earnings before interest, taxes, depreciation and amortization, as discussed and shown in this release, constitutes a non-GAAP “pro forma” financial measure.

We believe that Adjusted EBITDA, as a non-GAAP pro forma financial measure, provides meaningful information to investors in terms of enhancing their understanding of our operating performance and results, as it allows investors to more easily compare our financial performance on a consistent basis compared to the prior year periods. This non-GAAP financial measure also corresponds with the way we expect investment analysts to evaluate and compare our results. Any non-GAAP pro forma financial measures should be considered only as supplements to, and not as substitutes for or in isolation from, or superior to, our other measures of financial information prepared in accordance with GAAP, such as net income attributable to PowerSecure International, Inc.

We define and calculate Adjusted EBITDA as net income attributable to PowerSecure International, Inc., minus: 1) the gain on the sale of our unconsolidated affiliate, 2) discontinued operations and 3) interest income and other income, plus: 4) restructuring charges, 5) acquisition expenses, 6) income tax expense (or minus an income tax benefit), 7) interest expense, 8) depreciation and amortization and 9) stock compensation expense. We disclose Adjusted EBITDA because we believe it is a useful metric by which to compare the performance of our business from period to period. We understand that measures similar to Adjusted EBITDA are broadly used by analysts, rating agencies, investors and financial institutions in assessing our performance. Accordingly, we believe that the presentation of Adjusted EBITDA provides useful information to investors. The table below provides a reconciliation of Adjusted EBITDA to net income attributable to PowerSecure International, Inc., the most directly comparable GAAP financial measure.
