Buechler, Chairman, President and Chief Executive Officer - -more- SPARTECH CORPORATION FIRST QUARTER 2004 EARNINGS ADD 1 SPARTECH CORPORATION ANNOUNCES FIRST QUARTER FISCAL 2004 SALES AND EARNINGS INCREASES ST. LOUIS, March 4, 2004 - Spartech Corporation (NYSE:SEH) announced today increases in both sales and earnings for its first quarter ended January 31, 2004. Spartech's Chairman, President and CEO, Bradley B. Buechler, reported that sales for the first three months of fiscal 2004 were $241.5 million, a 13% increase from the Company's first quarter sales last year of $213.7 million. In addition, the Company's fiscal 2004 first quarter operating earnings rose to $18.8 million or 19% greater than the $15.7 million reported for the same quarter last year. These sales and operating results produced first quarter net earnings of $7.7 million or $.26 per diluted share, compared to $6.2 million, or $.21 per diluted share generated in last year's first quarter. Commenting on the results, Mr. Buechler stated, "We are pleased to report that our first quarter produced substantially improved results over the similar three-month period last year, and recent economic news, coupled with our record first quarter 43 new product transformation registrations, points toward a continuation of this trend through the balance of 2004. Volume shipped during the quarter totaled just over 317 million pounds, representing record first quarter volume for us and exceeding our prior year's similar period volume by 10%. First quarter fiscal 2004 net earnings, though not a record, also rebounded favorably compared to last year, producing a 25% increase in net earnings as capacity utilization rate increases and 2003 conversion cost reductions began to take hold." SEGMENT RESULTS Custom Sheet & Rollstock - Our Custom Sheet & Rollstock segment reported strong sales during the first quarter of 2004, principally due to a combination of rebounds in the transportation and building & construction markets we serve and new volume from our 2003 acquisitions of PEP and TriEnda. And more importantly, the group's operating margin improved modestly to 9.4%, with our focused conversion cost reduction efforts beginning to pay off, as evidenced by the segment's gross margin increase of more than one-half of a percentage point during the quarter. The group's capacity utilization rate grew each month during the period, which bodes well for the segment's second quarter. (In Millions) First Quarter 2004 2003 Net Sales $160.1 $139.8 Operating Earnings $ 15.1 $ 12.6 -more- SPARTECH CORPORATION FIRST QUARTER 2004 EARNINGS ADD 2 Color & Specialty Compounds - Our Color & Specialty Compounds segment saw reasonably solid orders from/sales to most markets served, with the exception of consumer electronics where the group's largest consumer products customer lost a portion of its business during fiscal 2003. This loss, which has its most significant impact when comparing the first quarter 2004 to the prior year similar period, all but offset the segment's solid gains in most other markets. The margin loss from this customer.approximately $.9 million or 1.3% of sales.offset a large part of the improvements in several other areas and resulted in a modest (.6%) decline in operating margin for the segment. Our late 2003 Creating Positive Change efforts have just started to positively effect our production efficiencies within the group and should help improve margins as the year progresses. (In Millions) First Quarter 2004 2003 Net Sales $ 66.5 $ 59.9 Operating Earnings $ 5.6 $ 5.4 Molded & Profile Products - Our Molded & Profile Products segment produced some solid increases in both sales (6%) and operating earnings ($.7 million) in the first quarter. Operating margin for the group experienced a nice rebound (3.9% to 8.3%) as volume improvement, notably in our custom molded wheels unit, coupled with focused cost reductions, produced some excellent results for this segment in the first quarter of 2004. (In Millions) First Quarter 2004 2003 Net Sales $ 14.8 $ 14.0 Operating Earnings $ 1.2 $ .5 Finally, Mr. Buechler stated, "As we move forward to our second quarter, we continue to see signs that our economy is improving.larger order sizes and more requests for quotes. We are also seeing an increase in acquisition candidates coming to market. And in light of British Vita's recent sale of its remaining ownership position in Spartech, we have expanded our geographic reach for acquisitions as we begin our efforts to become a more global company. Based upon all of the above, we currently believe that Spartech should generate year-over-year improved earnings results in each quarter during the remainder of fiscal 2004. Our current guidance for the full fiscal 2004 is $1.38-$1.43 earnings per diluted share, after factoring in the recent common stock offering, but before any additional acquisitions. Reconciling this to our previous guidance of $1.42-$1.47 per share.issued before our recent equity offering which generated proceeds for the Company of approximately $61 million.this current guidance considers an 8 cents per share reduction for dilution from the offering and a 3-4 cents per share increase due to our improved first quarter performance and a better outlook for the balance of the year. Once again, this guidance does not give any positive effect for acquisitions likely to be made later this year." -more- SPARTECH CORPORATION FIRST QUARTER 2004 EARNINGS ADD 3 Spartech Corporation is a leading producer of engineered thermoplastic materials, polymeric compounds, and molded & profile products, which has 47 facilities located throughout the United States, Canada, Mexico, and Europe, with annual production and sales in its recently completed fiscal year of more than 1.2 billion pounds and $950 million, respectively.
