Nature of Business: State-of-the-art time and frequency systems and equipment Total employees: 271 In Orange County: 87 Stock listing in The Times: On NASDAQ as “Datum” Ticker Symbol: “DATM” Friday’s Stock Close: $2.50 Change: Down $0.13 Analyst Review: “Datum makes time crystal oscillators and atomic clocks that are so accurate they can test Einstein’s theory of time and space travel. The problem is 75% of its products were geared to defense industry. It has been trying to convert to a more commercial base, but it is a difficult, slow process. One bright spot is that Datum acquired a Texas-based telecommunications company, Austron, which has become the heart of its growth. For now, the question is, ‘Is it going to be a winner in the stock market?’ The past year indicates that its going to be a wallflower at least for the short term, but if the company holds its own for the next two years, it has a good shot at working its way out if its malaise.” --Charles Kaplan, analyst Herzog Heine Geduld, New York SALES and PROFITS Dollar amounts in millions
