(Nasdaq: USTR) announced today that its organic sales for the two months ended November 30, 2000 were slightly below its stated target of 6% to 9%. "Although our rate of sales growth has slowed as we compare against strong growth in the prior year, we remain confident that United Stationers will achieve record sales and earnings for fiscal 2000," said Randy Larrimore, president and chief executive officer. "However, as a result of slowing top-line growth, earnings per share for fiscal 2000 will be in the range of $2.84 to $2.86." "We are pleased that our forecasted fiscal 2000 earnings per share growth of approximately 20% will exceed our stated target of 15% growth. This is particularly noteworthy given our significant investments in building our third-party fulfillment and logistics business," concluded Larrimore.
