Gibraltar Reports Record Quarterly Sales and Best-Ever Third-Quarter
Earnings; Net Income of $8.0 Million is the Highest for Any Third
Quarter in Company History

    BUFFALO, N.Y.--(BUSINESS WIRE)--Oct. 27, 2003--Gibraltar (Nasdaq:
ROCK) today reported its sales and earnings for the three and nine
months ended September 30, 2003.
    Sales of $208.0 million increased by approximately 20 percent from
$173.2 million in the third quarter of 2002, and were the highest for
any quarter in the Company's history. Sales in the first nine months
of 2003 were $573.0 million, a nine-month record, and an increase of
17 percent from $489.4 million in the first nine months of 2002.
    Net income of $8.0 million was a third-quarter record, and
increased 12 percent compared to $7.1 million in the third quarter of
2002. For the first nine months of 2003, net income was $21.1 million,
also a nine-month record, and an increase of 10 percent compared to
$19.1 million in the first nine months of 2002.
    Earnings per share in the third quarter of 2003 were $.49, an
increase of 11 percent from $.44 per share in the third quarter of
2002, on approximately the same number of weighted average shares
outstanding. During the first nine months of 2003, earnings per share
were $1.31, a five percent increase from $1.25 in the first nine
months of 2002, on a five percent increase in weighted average shares
outstanding as a result of Gibraltar's successful completion of its
secondary stock offering of 3,150,000 shares in March 2002.
    "We generated record sales and our best-ever third-quarter
earnings in an economy that - while showing signs of improvement -
clearly has a long way to go to get back to full health. We continue
to operate below peak levels, so there is considerable upside to our
sales and earnings potential as the economy resumes strong and
sustained growth," said Brian J. Lipke, Gibraltar's Chairman and Chief
Executive Officer.
    "Even with a struggling economy, Gibraltar has been able to
produce solid results in the first nine months of this year, unlike
many of its competitors," said Mr. Lipke. "The accretive acquisitions
of Construction Metals, acquired on April 1, and Air Vent, acquired on
May 1, which add approximately $100 million to our annual sales,
contributed to this year's success. We also paid down approximately
$30 million in debt during the third quarter, reducing our net debt to
total capital to 47.4 percent at September 30, 2003.
    "As we approach our tenth anniversary as a public company
(Gibraltar completed its initial public offering on November 4, 1993),
we continue to focus on those goals that brought us success throughout
our first decade: generating consistent sales and earnings growth;
shifting a greater share of our business into higher-value added,
higher-margin processes, products, and services; diversifying and
broadening our customer base, geographic reach, and business mix; and
improving our returns on sales, shareholders' equity, and investment,"
said Mr. Lipke.
    "We are proud of our performance during our first ten years as a
public company, especially the steps we took to make our company
stronger, not just bigger. Our strategic diversification allowed us to
consistently generate profitable growth, even when the economy
weakened. And today, we have more opportunities to strategically grow
and strengthen our business, through our existing operations and with
additional acquisitions, than at any point in our history," said Mr.
Lipke.
    Looking ahead, Mr. Lipke said that, "The fourth quarter is
historically our slowest period due to the reduced number of shipping
days as a result of holidays and plant shutdowns by our customers in
the automotive industry, and seasonal slowing in the building industry
due to weather conditions. This year, the normal seasonality will be
impacted by fourth-quarter production schedules by the automotive
companies that are below year-ago levels. Barring a significant change
in business conditions, we expect our fourth-quarter earnings per
share will be in the range of $.24 to $.30, compared to $.29 in the
fourth quarter of 2002, on approximately the same number of weighted
average shares outstanding, which would result in 2003 being a record
year for sales and earnings.
    "As we look ahead to the coming year, we see an increasing number
of positives, with an improving economy, interest rates hovering near
historic lows, the housing market showing sustained strength, and
aggressive growth plans from some of our largest customers. Coupled
with our focus on cost reduction - and as we further develop the
synergies from our newest acquisitions - we look at 2004 with
increasing optimism," said Mr. Lipke.
    Gibraltar is one of North America's leading metal processors, a
manufacturer of more than 5,000 steel and other metal products, and
North America's second-largest commercial heat treater. The Company
serves approximately 10,000 customers in a variety of industries in
all 50 states, Canada, and Mexico. It has approximately 3,900
employees and operates 67 facilities in 26 states, Canada, and Mexico.
    Information contained in this release, other than historical
information, should be considered forward-looking, and may be subject
to a number of risk factors, including: the impact of changing steel
prices on the Company's results of operations; changing demand for the
Company's products; risks associated with the integration of
acquisitions; and changes in interest or tax rates.

    Gibraltar will review its third-quarter results and discuss its
outlook for the fourth quarter during its quarterly conference call,
which will be held at 2 p.m. Eastern Time on October 27. Investors and
