Echelon Reports Fourth Quarter and Full Year 2012 Results

SAN JOSE, Calif., February 12, 2013 – Echelon Corporation (NASDAQ: ELON) today announced financial results for the fourth quarter and full year 2012 ended December 31, 2012.

• Q4 Revenues: $23.8 million

• Q4 GAAP Net Loss: $4.1 million; GAAP Net Loss per Share: $0.10

• Q4 Non-GAAP Net Loss: $2.7 million; Non-GAAP Net Loss per Share: $0.06

• 2012 Revenues: $134.0 million

• 2012 GAAP Net Loss: $12.8 million; GAAP Net Loss per Share: $0.30

• 2012 Non-GAAP Net Loss: $4.7 million; Non-GAAP Net Loss per Share: $0.11

“While 2012 was a challenging year in the smart grid market, we made some significant strides in Echelon’s strategic transformation. We entered new territories with our subsystems strategy, developed new advanced metering products via our Echelon-Holley joint venture and successfully implemented cost saving and gross margin enhancing initiatives,” said Ron Sege, chairman and CEO of Echelon.

“We ended the fourth quarter with a number of promising system and sub-system pilots and deployments, indicating that our strategy of targeting geographies with strong fundamentals for investment in grid modernization is sound. As we expect 2013 to be another year of modest demand in the smart grid market, we will continue the difficult task of restructuring our operations while investing in our strategic initiatives.”

Total revenues for the fourth quarter were $23.8 million, down from $40.5 million in the same period last year. Revenues from Echelon’s systems sales, reflecting sales to our utility customers, were $10.7 million for the fourth quarter, down from $26.4 million in the same period last year. Revenues from Echelon’s sub-systems, largely from commercial customers, were $13.1 million in the fourth quarter, down from $14.2 million a year ago. Included in sub-systems revenues were $2.9 million of sales to Enel in the fourth quarter compared to $2.1 million in the same period last year.

For the full year of 2012, revenues were $134.0 million compared to $156.5 million in 2011. System and sub-system revenues both decreased 14% to $85.2 million and $48.8 million, respectively. Within sub-system sales, Enel project sales decreased 9% to $6.5 million.

Gross margin in the fourth quarter of 2012 was 47.0% compared to 39.2% in the fourth quarter of 2011. Total operating expenses for the quarter were $14.9 million compared to $19.8 million in the fourth quarter of 2011.

GAAP net loss for the fourth quarter was $4.1 million, or $0.10 cents per share, compared to a net loss of $4.2 million, or $0.10 cents per share, in the same period last year. Non-GAAP net loss for the fourth quarter was $2.7 million, or $0.06 cents per share, compared to a non-GAAP net loss of $1.3 million, or $0.03 cents per share for the fourth quarter of 2011.

GAAP net loss for the full year of 2012 was $12.8 million, or $0.30 cents per share, compared to GAAP net loss of $13.0 million, or $0.31 cents per share, for the same period in 2011. Non-GAAP net loss for the year was $4.7 million, or $0.11 cents per share, compared to non-GAAP net loss of $3.4 million, or $0.08 cents per share in 2011.

Restructuring Charge

The company expects to incur a $2.5 to $3.0 million restructuring charge in the first quarter related to a workforce reduction that will affect approximately 15% of its employees. These actions are expected to be implemented over the next 12 months.

Business Outlook

Echelon offers the following guidance for the first quarter of 2013:

• Total revenues are expected to be between $24.0 million and $26.0 million, with systems and sub-systems revenues accounting for about 50% each.

• Non-GAAP gross margin is expected to be approximately 45-46%.

• Stock-based compensation expense is expected to be approximately $1.0 million.

• Non-GAAP loss per share amounts are expected to range from $0.06 to $0.11, based on a fully diluted weighted average shares outstanding of 43.0 million.

• GAAP loss per share is expected to be between $0.16 and $0.21.

For those interested in further discussion regarding this release, Echelon’s management will participate in a conference call today at 2:00 p.m. Pacific/5:00 p.m. Eastern Time. To access the call, dial 888-771-4371 or 847-585-4405 outside the U.S and provide the confirmation number 34104452. An archived replay of the webcast will be available approximately two hours following the end of the call.

Use of Non-GAAP Financial Information

Echelon continues to provide all information required in accordance with GAAP, but believes that an investor’s evaluation of our ongoing operating results may not be as useful if an investor is limited to reviewing only GAAP financial measures. Accordingly, we provide non-GAAP net income and non-GAAP net income per share data as additional information relating to Echelon’s operating results. Echelon presents these non-GAAP financial measures to provide investors with an additional tool for evaluating Echelon’s operating results in a manner that focuses on what Echelon believes to be its ongoing business operations. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income or net income per share prepared in accordance with GAAP.

Echelon’s management uses certain non-GAAP financial information, namely operating results excluding restructuring charges as well as the impact of stock-based compensation charges made in accordance with ASC 718 (formerly SFAS 123R), to evaluate its ongoing operations and for

internal planning and forecasting purposes. Accordingly, we believe it is useful for Echelon’s investors to review, as applicable, information that both includes and excludes these charges (and the related tax impact) in order to assess the performance of Echelon’s business and for planning and forecasting in future periods. Whenever Echelon reports such non-GAAP financial measures, a complete reconciliation of the non-GAAP financial measure to the most closely applicable GAAP financial measure is provided. Investors are encouraged to review these reconciliations to ensure they have a thorough understanding of the reported non-GAAP financial measures and their most directly comparable GAAP financial measures.
