LYTS LSI Industries Inc

LSI Industries Inc. (Nasdaq:LYTS) today announced the following:

* Based on preliminary information, operating results for the third quarter ended March 31, 2010 are expected to show net sales of between $52,000,000 and $53,500,000 and a net loss of between $(2,600,000) and $(2,100,000), or a diluted per share loss of between $(0.11) and $(0.09). Included in the results for the third quarter is a loss of approximately $700,000 related to the previously announced sale of the operating assets, facility, and business of LSI Marcole.

Although LSI Industries does not provide net sales and earnings guidance to the financial markets, it deemed this    preliminary disclosure appropriate since analyst estimates for the third quarter place net sales between $52 million and $64 million and diluted per share earnings between $0.00 and $0.05.

For the fiscal year ending June 30, 2010, LSI Industries believes net sales will be between $248 million and $260 million, net income will be between $1.8 million and $2.6 million, and diluted per share earnings will be between $0.07 and $0.10.

* LSI Industries was recently informed by a large national convenience store customer that it intends to expand its re-imaging program utilizing solid-state LED lighting to an additional 2,800+ non-petroleum sites. LSI expects to begin working on this program during the current quarter, with the expectation that it will be completed in 12 to 18 months.

* Management intends to provide additional comments on actual third quarter and expected fiscal 2010 operating results, as well as the LED lighting re-imaging program, when it reports its third quarter operating results, which is scheduled for April 22, 2010.
