Dear Customers and Partners,

We are excited to inform you that Echelon’s Board of Directors has just accepted an offer to be acquired by Adesto Technologies. Like Echelon, Adesto is a NASDAQ-listed company focused on serving the needs of the IoT market. They are a leader in providing innovative semiconductors, and their technology is used by more than 2,000 customers worldwide, including a large number of industrial focused companies.

The combination of the two IoT companies will allow greater resources to be applied to developing and supporting products and solutions in this rapidly growing and dynamic market. With complementary products and a shared strategic vision, Echelon and Adesto will be in a stronger position to meet the current and future needs of customers.

The acquisition is expected to close later in Q3 of this year, pending shareholder approval.

Additional information about the acquisition will be posted on the Echelon website in the coming weeks. Please contact info@echelon.com if you have any questions.

We really appreciate your business, and look forward to meeting your needs in the future.

Sincerely,

Ron Sege, Chairman and CEO

Echelon Corporation

Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this document, including the following, among others: Echelon stockholders may not approve the transaction; closing of the transaction may not occur or may be delayed; expected synergies and other financial benefits of the transaction may not be realized; integration of the acquisition post-closing may not occur as anticipated; litigation related to the transaction may delay or negatively impact the transaction; unanticipated restructuring costs may be incurred or undisclosed liabilities assumed; attempts to retain key personnel and customers may not succeed; the business combination or the combined company’s products may not be supported by third parties; actions by competitors may negatively impact results; and there may be negative changes in general economic conditions in the regions or the industries in which Adesto and Echelon operate. In addition, please refer to the documents that Adesto and Echelon file with the Securities and Exchange Commission on Forms 10-K, 10-Q and 8-K. These filings identify and address other important risks and uncertainties that could cause events and results to differ materially from those contained in the forward-looking statements set forth in this document. Readers are cautioned not to put undue reliance on forward-looking statements, and Adesto and Echelon assume no obligation and do not intend to update these forward-looking statements, whether as a result of new information, future events or otherwise.

The Company plans to file a proxy statement (the “Transaction Proxy Statement”) with the Securities and Exchange Commission (the “SEC”) in connection with the solicitation of proxies in connection with the Transaction.

Ronald A. Sege, Robert J. Finocchio, Jr., Armas Clifford Markkula, Jr., Robert R. Maxfield and Betsy Rafael, all of whom are members of the Company’s Board of Directors, and C. Michael Marszewski, Vice President and Chief Financial Officer, are participants in the Company’s solicitation. Of such participants, each of Messrs.

Additional information regarding such participants, including their direct or indirect interests, by security holdings or otherwise, will be included in the Transaction Proxy Statement and other relevant documents to be filed with the SEC in connection with the Transaction.
