STERLING, VA and LOVELAND, CO--(June 22, 2015) - Sutron Corporation (STRN) and Hach Company are pleased to announce the entry into a definitive merger agreement, pursuant to which an affiliate of Hach Company will acquire Sutron Corporation by making a cash tender offer to acquire all outstanding shares of common stock of Sutron, at a purchase price of $8.50 per share, for a total enterprise value of approximately $39 million, net of cash.

Sutron would become a part of Hach Environmental, a group of companies including Ott Hydromet and Sea-Bird Scientific, that serves customers with high quality and reliable instruments focused on environmental monitoring solutions for natural resource and oceanographic applications. The addition of Sutron to the group is expected to provide many benefits, including the addition of core technologies in satellite communications, advanced air quality instrumentation, and highly sophisticated meteorological software solutions.

Glenn Cruger, President of Hach Environmental, said "Sutron is an excellent complement to Ott Hydromet's portfolio of water quality, quantity and telemetry solutions with global reach that meets customer's needs for integrated, seamless hydromet networks of sensors, communications and software. This combination will further build out our strong platform of environmental monitoring solutions designed to help our customers solve their most challenging water resources problems."

Sutron's Chairman, Chief Executive Officer and President, Raul McQuivey, said "I believe this transaction represents an outstanding opportunity for our shareholders, employees, and customers. As part of Hach Environmental, Sutron's commitment to providing robust environmental monitoring solutions to hydromet, meteorological and air quality professionals will continue, and we will be able to expand our capability to provide the end-to-end solutions our customers have been asking of us."

The Sutron Board of Directors has unanimously recommended that Sutron shareholders accept and tender their shares into the offer. The offer is subject to customary conditions, including tender of 66 2/3 percent of the outstanding shares into the offer, on a fully diluted basis, and the absence of a material adverse change with respect to Sutron. The transaction is expected to be completed in the third quarter of 2015.
