Alliant Techsystems
(NYSE:) reported today that earnings per share in the second quarter rose
to $1.15. The second quarter results did not include a benefit for the R&D
tax credit. ATK’s prior EPS guidance of $1.17 included a benefit of five
cents per share for the R&D tax credit. The company believes that the R&D tax
credit will be extended retroactively prior to the end of its fiscal year.

Sales for the quarter, which ended October 1, climbed eight percent to
$833 million from $772 million in the prior year quarter. Sales were driven
entirely by organic growth. Orders in the quarter were up 44 percent to
$944 million from $656 million in the prior year period. The company’s second
quarter EBIT margin (earnings before interest and income taxes as a percent of
sales) was 9.8 percent — up from 9.7 percent in the first quarter and on
track for full-year EBIT performance of approximately 10 percent. Due in part
to the delay of the research and development tax credit extension, the
company’s tax rate for the quarter was 37.8 percent compared to 34.5 percent
in the prior year.

“I’m pleased with ATK’s strong second-quarter and believe we are well
positioned to finish the fiscal year with double digit earnings growth, a
strengthening orders profile and the momentum to sustain our growth,” said Dan
Murphy, Chairman and Chief Executive Officer. “We achieved several notable
successes in the quarter including significant new positions in commercial
aerospace and nuclear power generation,” said Murphy.

    Key order highlights:

    --  Multi-year, multi-million dollar award for composite containment cases
        on the GEnx aircraft engine
    --  An initial $10 million award for rotor tubes used in a centrifuge
        operation to enrich uranium for nuclear power generation
    --  $41 million to provide the U.K. with anti-tank barrier systems
    --  $83 million in medium-caliber ammunition
    --  $66 million in small-caliber ammunition


    Additional business highlights:

    --  Completed a $300 million convertible security offering which allows
        the company to fully fund its pension plan in FY07
    --  Completed the repurchase of 2.6 million shares of stock during the
        quarter for approximately $202 million.
    --  The company's senior secured debt was raised to investment grade
        status (Baa3) by Moody's Investors Services
    --  The successful test firing of a Kinetic Energy Interceptor (KEI) first
        stage motor
    --  The formation of an ATK, Lockheed Martin, and Pratt & Whitney
        Rocketdyne team to pursue the upper stage of the Ares I launch vehicle

Earnings per share for the first six months of fiscal year 2007 increased
nine percent to $2.24 compared to $2.06 a year ago. The prior year results
included tax benefits of 9 cents per share. Sales for the first half of
fiscal year 2007 rose more than eight percent to $1.66 billion from
$1.53 billion in the prior year. First half orders reached $1.56 billion, a
16 percent increase from $1.34 billion reported in the prior year.

Year-to-date operating cash is $5 million compared to $116 million in the
prior year quarter. The decrease reflects ATK’s previously announced capital
deployment strategy to fully fund its employee pension plan obligations.

QUARTERLY SEGMENT RESULTS

ATK operates three principal business groups: Ammunition Systems Group;
Launch Systems Group; and Mission Systems Group.

AMMUNITION SYSTEMS

Sales from the Ammunition Systems Group increased 12 percent to
$283 million from $252 million in the prior year quarter, led by an 18 percent
rise in civil ammunition sales and continued strength in the company’s
military small-caliber ammunition business. Based on the strength of the
Group’s civil ammunition sector through the first half of the year, ATK now
believes that sales growth for the Group will exceed 10 percent.

Second quarter earnings before interest and taxes (operating profit) for
the Ammunition Systems Group were $26 million, compared to $24 million in the
prior year quarter. This reflects the growth of civil ammunition and medium-
caliber ammunition. The company continues to expect full-year operating
margins in the Ammunition Systems Group of more than 9 percent.

LAUNCH SYSTEMS

Sales from the Launch Systems Group increased five percent to $262 million
versus $250 million in the prior year quarter. This increase reflects new
sales from NASA’s Ares I program. ATK continues to expect mid-single-digit
growth for the full year.

Second quarter operating profit for the Launch Systems Group was
$35 million compared to $37 million in the prior year. This reflects
reductions in sales and margins on ordnance programs and Orion motors,
partially offset by increased volume and favorable contract performance on
strategic programs. The company continues to expect full-year margins in the
Launch Systems Group of approximately 14 percent.

MISSION SYSTEMS

Mission Systems sales increased seven percent to $288 million compared to
$270 million in the prior year quarter. The increased sales were driven by
new sales from the recently announced GEnx contract, higher AAR-47 missile
warning system volumes, increases in sales from the company’s aircraft
integration business, and higher sales in large-caliber ammunition. These
were partially offset by expected lower sales from advanced weapons. ATK
expects that the Mission Systems Group will achieve mid single-digit organic
growth for the full year.

Second quarter operating profit was $26 million, up from $21 million in
the previous year. The increase reflects improved margins in electronic
warfare and fuzing programs as well as the elimination of fuze restructuring
costs associated with the consolidation of fuze operations in West Virginia.
The company continues to expect operating margins for the full year of more
than 9 percent.

OUTLOOK

Based on better visibility into the remainder of the fiscal year, ATK is
raising its full-year FY07 sales estimate and narrowing its EPS range to the
upper end of its previous guidance. ATK now expects sales to exceed
$3.45 billion. It previously expected sales to exceed $3.4 billion. ATK is
also raising its FY07 orders guidance to approximately $3.6 billion, up from
prior guidance of $3.3 billion. The company now expects full-year EPS in a
range of $4.95 – $5.05. The previous guidance range was $4.90 – $5.05. ATK
is raising its guidance related to cash flow from operations to $35 million,
from $25 million. ATK’s cash guidance includes the impact of the planned
$385 million pension contribution this year, partially offset by expected tax
benefits.

The company expects average share count of less than 35 million in FY07.
The effective tax rate is expected to be approximately 35 percent (assuming
the research and development tax credit is extended retroactively to the
beginning of the company’s fiscal year). Pension expenses are expected to be
approximately $70 million.

ATK is a $3.4 billion advanced weapon and space systems company employing
approximately 15,000 people in 22 states. News and information can be found
