BMC Industries, Inc. Releases Expectations For Second Quarter 2001

June 7, 2001 – Minneapolis, Minnesota, USA – BMC Industries, Inc. commented today that both of its businesses continue to be impacted by the slowing global economy and by external market factors similar to those affecting the businesses in the first quarter 2001.  As a result, financial results for the second quarter 2001 will be negatively affected.

The Buckbee-Mears group is experiencing significant pricing pressure in its computer monitor mask business as a result of continuing weakness in worldwide demand for computer monitors.  In addition, the group is projecting a decline in demand for television masks, particularly jumbo-size television masks, for the second quarter 2001.  The group attributes the drop in demand to a build-up of excess inventory at several picture tube customers.  It is currently anticipated that television mask demand will rebound after this excess inventory position is corrected.  Micro-Technology sales and earnings also remain sluggish as its customers continue to react to slowed economic conditions.

The Optical Products group’s results continue to be negatively impacted by a flat domestic ophthalmic lens market and the following unanticipated factors: temporary SunSport™ product supply constraints and delays in a major customer’s conversion to a new product line hindering second quarter SunSport™ sales; accelerated erosion of the domestic glass market; polycarbonate sales growth inhibited by capacity issues (in the process of being addressed and therefore believed to be temporary) in certain product lines; and unplanned distribution costs attributable to the consolidation of depots and to backorder freight expense caused by the above-described polycarbonate capacity issues.  This group’s results will also be negatively impacted by increases in selling and administrative expenses as the group has added infrastructure to support expansion and sales growth initiatives, with the offsetting revenue growth expected to be realized in future quarters.  Finally, while polycarbonate and glass product cost reduction efforts continue to proceed as planned, the full impact of these initiatives will be delayed and will grow progressively over the course of the year due to average product costing methodology.

“We are finding the second quarter business environment to be more difficult than expected for both of our operations,” said BMC Chairman and Chief Executive Officer Paul B. Burke.  “While we are taking aggressive action to respond to these difficult conditions, we will protect the Vision-Ease sales and distribution infrastructure we have been in the process of building as we expect these capacity issues to be resolved in the short term.  We continue to see tremendous growth potential in this business and we are working to resolve the capacity issues in order to be in a position to capitalize on that potential when market conditions improve.”

Due to the conditions outlined earlier, BMC expects to report consolidated revenues of approximately $80 to $85 million for the second quarter 2001.  Revenues in the second quarter of 2000 were $94.2 million.  As a result of the sales shortfall and the Vision-Ease costs mentioned earlier, BMC expects to report diluted earnings per share in the range of $0.09 to $0.12 for the second quarter of 2001.  The Company earned $0.20 per diluted share in second quarter 2000.  The Company continues to reassess its outlook for the last half of 2001 and will address its forecast for the remainder of the year with its second quarter earnings release in July.
