Net sales for the quarter were $2.50 million, up from $2.37 million, or approximately 6% from the same period in 2002. Net income for the quarter was $243,000, or $0.06 per diluted share, up from $32,000, or $0.01 per diluted share, in the first quarter of 2002. The Company has now been profitable in each of the past seven quarters. Scott C. McDonald, President and CEO, stated, "Our recent results are further indication that Castelle's strategy of introducing advanced new products, maintaining growth in domestic sales while expanding overseas is paying off. We continue to be pleased by the response to our FaxPress(TM) 7.0 network fax software, which began shipping last November. It is also significant that Castelle just recorded its seventh straight profitable quarter, despite some of the toughest quarters in the history of the technology sector." Positive Developments in First Quarter 2003 During the first quarter of 2003, Castelle took steps to enhance its sales efforts both in the U.S. and internationally. On the domestic front, Castelle promoted Todd Olsen to the new position of Director of Distribution Sales, with a focus on strengthening the Company's relationship with its U.S. distributors. Castelle continues to experience strong contributions from its key U.S. distributors, Ingram Micro (NYSE: IM) and Tech Data (Nasdaq: TECD). Internationally, Castelle announced the addition of new resellers in Europe and Latin America. The new European resellers, recruited by AMS Ltd, Castelle's master distributor for the UK and Europe, are based in France, Italy, Norway and Estonia. Castelle also established strategic partnerships with five resellers based in three Latin American countries - Mexico, Chile and Brazil. Castelle continues to expand into international markets, and recently exhibited at CeBIT Europe in the Novell Partner Pavilion. Castelle's new LANpress(R) 2000 USB network print server was introduced on April 1, 2003. The LANpress 2000 USB is a multi-protocol print server that allows a printer with a USB connection to be shared by Microsoft, Novell, UNIX/Linux and Macintosh users. Although the Company's FaxPress network fax servers are its principal revenue-generating products, Castelle has also been selling print servers for over 10 years and intends to continue expanding and updating that product line. Balance Sheet Remains Strong "With our solid balance sheet, which includes $3.36 million in cash and nearly zero debt, Castelle remains in a strong position for continued growth."
