Aehr Test Systems (AEHR), a supplier of semiconductor test and burn-in equipment, announced financial results for the first quarter of fiscal 2009 this afternoon after the close. Revenues rose to $9.7 million, an increase of 27% from $7.7 million for the same period of fiscal 2008. Income from operations was $1.4 million, an increase of 89% from $717,000 a year earlier. Net income rose 21% to $865,000, or 10 cents per share, compared to $717,000, or 9 cents per share last year. The smaller increase in net income relative to the rise in operating income is a result of a significantly higher effective income tax rate.
