SECOND QUARTER 2003 EARNINGS

                      SPARTECH CORPORATION ANNOUNCES

                    SECOND QUARTER FISCAL 2003 RESULTS


     ST. LOUIS, May 29, 2003 - Spartech Corporation (NYSE:SEH) announced
today sales and earnings increases for its second quarter ended May 3,
2003.

     Spartech's Chairman, President and CEO, Bradley B. Buechler, reported
that sales for the second quarter of fiscal 2003 were $250.5 million, an
increase of 7% from the $233.2 million reported in 2002.  The Company's
fiscal 2003 second quarter operating earnings were $22.5 million or 5%
greater than the $21.3 million reported for the same quarter last year.
Second quarter 2003 net earnings were $10.5 million, or $0.36 per diluted
share, compared to the $9.1 million, or $0.33 per diluted share, reported
in 2002.

     Commenting on the results, Mr. Buechler stated, "Our second quarter
generated some reasonably strong results considering the events which
occurred during this three month period.  The crisis in the Middle East,
along with near record high crude oil and natural gas prices, produced
unprecedented and rapid increases in the cost of the Company's raw
materials during the quarter.  This, coupled with the sluggish economy,
resulted in some very intense pressure on our margins during this period.
However, despite these negative events, we were able to generate increases
in both Sales (7%) and Net Earnings (16%) during the quarter, as our cost
control efforts and new Product Transformation volume remained strong."

SEGMENT RESULTS

     Custom Sheet & Rollstock - Spartech's Custom Sheet & Rollstock group,
     which represents approximately two-thirds of the Company's
     consolidated results, saw modest growth of 2% in sales volume (pounds)
     during the second quarter of fiscal 2003.  However, our second quarter
     sales in dollars for the segment increased by more than 3%, primarily
     due to changes in product mix, higher average resin costs and our late-
     March acquisition of Polymer Extruded Products.  In addition, the
     group's 11% second quarter operating margin moved closer to our 12-13%
     target for this segment, as (1) operating results improved
     significantly at our Spartech Polycast unit; (2) certain cost
     reduction initiatives implemented last year began to show some
     positive returns; and (3) new Product Transformation volume continued
     strong.

ADD 2



     Color & Specialty Compounds - Sales volume (in pounds) for the
     Company's Color & Specialty Compounds group rose by 5% in the second
     quarter, with this increase primarily coming from last year's late-May
     acquisition of GWB Plastics.  However, the group's operating margin
     suffered its largest decline in the past five years.to 7.6%...as the
     unit saw its cost of raw materials increase, on average, by more than
     40% during the period.  While progress was made late in the quarter in
     raising our sales prices to offset the higher raw material costs, we
     were not able to cover the full impact of the raw material inflation
     during the period.  The group initiated over $2 million in cost
     reductions midway through the quarter and this coupled with the
     announced sales price increases should help this segment return to its
     historical margin levels (11-13%) in the second half of fiscal 2003.

     Molded & Profile Products - The Company's Molded & Profile Products
     segment (approximately 8% of consolidated results) generated modest
     increases in sales and operating earnings during the quarter, as
     compared to last year's similar period.  Margins in the group remained
     fairly constant between years, as softness in the profiles unit was
     offset by improved operating results within our acrylic rods business.

     Finally, Mr. Buechler stated, "As we move into the second half of our
fiscal year, the economy yet to show any substantive signs of a sustainable
turnaround developing for the last six months of the year.  Therefore, we
continue to closely monitor our costs, while we also attempt to grow our
volume both internally, and through strategic expansions, in these
challenging times.  However, despite the competitive pricing pressures
which traditionally accompany this type of an economic environment, we are
reasonably confident that our Focused Growth and Continuous Improvement
Strategies will enable us to generate stronger results for the second six
months of our fiscal year, compared to those produced during the first half
of fiscal 2003."
