Echelon Reports 2010 Third Quarter Results

(SAN JOSE, CA –November 3, 2010) - Echelon Corporation (NASDAQ: ELON) today announced financial results for the third quarter ended September 30, 2010.

“Echelon delivered a solid quarter led by the strong performance in our LonWorks product line for commercial customers,” said Ron Sege, president and CEO of Echelon. “During the quarter we introduced the Echelon Control System (ECoS), our open software platform for intelligent distributed control, and the Echelon Control Node (ECN) 7000 product line, and we are excited to have Duke Energy as our first electric utility customer for these ground-breaking additions to our NES smart grid solution. We also announced our ControlPoint module, which expands intelligence beyond the meter by allowing third party developers to build intelligent devices based on the newly announced Open Smart Grid Protocol (OSGP).”

“Overall the third quarter was an important quarter of innovation for Echelon. We continued to deliver products that bring the ‘power of control’ to the increasingly dynamic electric grid edge – an important area of previously untapped opportunities between the electrical transformers in a residential area and the consumer and utility devices beyond. With ECoS, ECN, ControlPoint and OSGP we are enabling the integration of devices and applications into a utility’s open-standard NES-based smart grid so it can be managed and controlled as a single high performance and efficient infrastructure, which our customers tell us is a top priority,” continued Sege.

Total revenues for the quarter were $27.1 million compared to $27.0 million in the second quarter of 2010 and $23.7 million for the third quarter of 2009. Revenues for Echelon’s LonWorks^® infrastructure (LWI) products, sold to commercial markets, were $12.5 million in the third quarter, up from $11.9 million in the second quarter and $11.0 million in the same period last year. Revenues for Networked Energy Services (NES) products, sold to electric utilities, were $13.0 million for the third quarter, down from $13.5 million in the second quarter, but up from $11.5 million in the same period last year. Enel revenues were $1.5 million, roughly flat with $1.6 million in the second quarter and up from $1.2 million in the same period last year.

Gross margin for the third quarter of 2010 was 46.0% compared with 41.2% in the second quarter of 2010 and 43.5% for the third quarter of 2009. The sequential increase in margin was driven by improved margins in our NES product line. Total operating expenses for the quarter were $19.2 million compared to $17.9 million in the second quarter of 2010 and $17.8 million in the same period a year ago.

GAAP net loss for the third quarter was $7.8 million, or $0.19 cents per share, compared to a net loss of $6.9 million, or $0.17 cents per share, in the second quarter of 2010 and a net loss of $8.2 million, or $0.20 cents per share, for the third quarter of 2009. Non-GAAP net loss for the third quarter was $4.7 million, or $0.11 cents per share, compared to $3.9 million, or $0.09 cents per share for the second quarter of 2010 and a non-GAAP net loss of $4.6 million, or $0.11 cents per share, for the third quarter of 2009.

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 the impact of stock-based compensation charges made in accordance with 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 stock-based compensation (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.
