           Rogers Corporation Reports First Quarter Results

    ROGERS, Conn.--(BUSINESS WIRE)--April 21, 2005--Rogers Corporation
(NYSE:ROG) announced today that for the fiscal first quarter of 2005,
earnings per diluted share were $0.30, compared to the $0.72 earned in
the first quarter of 2004. The Company's first quarter guidance was
earnings of $0.28 to $0.32 per diluted share. Net income for the
quarter was $5.1 million.
    Net sales in the first quarter were $86.5 million, compared to the
$97.7 million sold in the first quarter of 2004. The Company had
provided a first quarter guidance range for net sales of $85 to $89
million.
    Printed Circuit Materials segment sales totaled $39.7 million,
down 12% from the first quarter of 2004, when customers were building
significant inventory. This business segment's operating profit was
$3.8 million, compared to $8.5 million a year ago. Flexible laminate
circuit material sales were significantly lower due to major cell
phone programs reaching end of life. The Company expects its
customers' new programs to ramp up late in the second and into the
third quarter. High frequency circuit material sales, driven by
resumed cellular infrastructure orders, increased significantly over
the fourth quarter and satellite TV market sales remained strong
throughout the quarter.
    First quarter sales of High Performance Foams were $23.4 million,
up 6% from the first quarter of last year, and just below last
quarter's all-time record. Operating income for the segment was $1.3
million in the quarter, up from $0.7 million a year ago. Foam sales
were driven by PORON(R) polyurethane materials, with strong results in
industrial applications and consumer markets. BISCO(R) silicone foam
sales were also up slightly over last year, while polyolefin foam
sales were down as the Company continued to eliminate unprofitable
business. At the Carol Stream, IL facility, Rogers has made progress
in its polyolefin operations and reduced the loss from last year
despite reduced sales.
    Sales of Polymer Materials and Components totaled $23.5 million
for the quarter, compared to last year's first quarter sales of $30.5
million. The expected decline in Durel sales accounted for almost all
of this business segment's decrease. However, demand for Rogers' new
DFLX(TM) flexible electroluminescent lamp (EL), used in keypad
applications, is exceeding expectations. The Company is currently
adding EL capacity worldwide, and expects to have two to three times
the current capacity for lamp production in place by the end of the
first quarter of 2006. Sales of the Company's elastomer components
were down from a year ago, when customers were building inventory in
preparation for the business transition to China. Operational
improvements continue at the new facility in China, and by the end of
April, the Company expects to have sold the majority of the U.S.
elastomer components product inventory built in anticipation of the
business transition. Rogers' first busbar shipments from the new China
operation were made at the end of the quarter. All indications are
that this incremental business will grow rapidly, as the Company can
now satisfy the requirements of Asian customers for local
manufacturing. Rogers expects this new busbar operation to be
profitable by the end of the year.
    Rogers' 50% owned joint ventures had quarterly sales of $23.9
million, an increase of 32% year-over-year. Rogers Chang Chun
Technologies (RCCT) flexible laminate circuit material sales increased
44% year-over-year. The Company's two polyurethane foam joint ventures
with Inoac Corporation also had significant sales growth, with a
combined increase of 51% over last year. Additionally, as expected,
the new polyurethane foam joint venture operation in China turned
profitable in the quarter. Polyimide Laminate Systems (PLS) revenues
declined due to lower market share for the joint venture's existing
products. Looking forward, PLS expects sales to grow as the
introduction of their new products was very favorably received.
    First quarter gross margin was 27.0%, down from 34.2% a year ago,
when the Company had significantly less production capacity and higher
sales. The corporate tax rate for the first quarter was 24%, which
reflects the beginning of benefit from increased activity in
jurisdictions with lower tax rates.
    The Company generated $6.8 million in operating cash flow, which
exceeded this quarter's capital expenditures of $4.2 million. The
Company's cash and short-term investments increased by $0.7 million
after repurchasing $7.0 million of the Company's common stock in the
quarter under its stock repurchase program. As anticipated, Rogers
made significant progress improving its balance sheet during the
quarter, reducing inventories by $4.1 million; accounts receivable by
$4.0 million; and decreasing accounts payable liabilities by $6.0
million. The Company continues to be debt free, and capital
expenditures continue to be funded from operations.
    Robert D. Wachob, President and CEO, commented, "Both sales and
profits for the quarter were in line with our expectations. Although
lower than we would like, this quarter's profit was affected by
significant product mix changes, continued process improvement
expenses, the new operations both in the U.S. and China, and also
under-utilized new capacity in certain product lines. Despite the
unfavorable comparison to the first quarter of 2004, when we had
considerably more operating leverage, we are very pleased with our
progress this quarter. In particular, I am very pleased with the
success and market demand for Durel's flexible keypad lamp, the steady
product sales and operational improvements in our new and relocated
facilities, and the progress in reducing our inventories. We look
forward to making continued improvement throughout the year and expect
second quarter net sales to be in the range of $89 to $93 million, and
profits between $0.40 to $0.44 per diluted share."
