drug emporium inc., citing increased competition from grocery stores, posted a fiscal third-quarter loss and said it may further tighten management ranks. the discount drugstore chain said it had a loss of $2.9 million, or 17 cents a share, in the quarter ended nov. 28. in the year-ago quarter, drug emporium earned $637,000, or five cents a share, on sales of $177.8 million. total sales in the quarter rose 3.1% to $183.3 million, but same-store sales declined 4%. "in a low-cost, low-margin business, a number like 4% is significant," said vice chairman gary wilber. results were also hurt by increased sales, general and administrative costs, which increased 15% to $39.2 million for the quarter, said gary dennis, an analyst at j.c. bradford in knoxville, tenn. mr. wilber said the chain took several cost-cutting steps in the last month, including laying off three executives and eliminating their posts. the three are richard landers, who was vice president of merchandise and marketing; robert ramsey, director of marketing; and frank shanower, vice president of trade relations. drug emporium also cut management pay by 5%, froze hiring and eliminated some executive perquisites. mr. wilber said the board will consider further cuts when it meets later this month. the chain has been in constant turmoil in recent years. in the last 18 months, it has fired two chief financial officers, retired its founding chairman and chief executive, philip i. wilber, and shunted mr. wilber's successor, his son gary, into the newly created post of vice chairman. the new chairman and chief executive, longtime director david l. kriegle, assumed his posts last week. the elder mr. wilber remains on payroll as a founding chairman. but that post may be eliminated, along with three other posts, later this month, the younger mr. wilber said. investors had hoped that drug emporium could push through price increases after rival phar-mor inc. filed for bankruptcy-law protection last year. but instead, drug emporium found increased competition from grocery stores with health and beauty sections, and from mass merchandisers such as wal-mart stores inc. given all the competition, "i don't think drug emporium has a particularly viable format," scott & stringfellow inc. analyst neal kaplan said. drug emporium is a national chain of 136 company-owned stores and 98 franchised stores. in national over-the-counter trading yesterday, its shares slipped 62.5 cents to $4.875.
