TABLE OF CONTENTS

PART I

ITEM 1.    BUSINESS

        Alliant Techsystems Inc. (ATK), which is sometimes called the Registrant in this report, is a supplier of aerospace and defense products to the U.S. Government, U.S. allies, and major prime contractors. ATK is also a supplier of ammunition to federal and local law enforcement agencies and commercial markets.

        ATK was incorporated as a Delaware corporation as a wholly-owned subsidiary of Honeywell Inc. in May 1990 in connection with Honeywell's plan to spin-off to its stockholders its Defense and Marine Systems Business, its Test Instruments Division, and its Signal Analysis Center. The spin-off became effective in September 1990, when Honeywell transferred to ATK substantially all of the assets and liabilities of those businesses. Honeywell subsequently distributed to its stockholders in October 1990 all of ATK's outstanding common stock on a pro rata basis.

        The following table summarizes ATK's significant acquisitions and divestitures:

        ATK conducts its business through a number of separate legal entities that are listed on Exhibit 21 to this report. These legal entities are grouped under holding companies that correspond to ATK's operating segments. During fiscal 2003, ATK had three operating segments: Aerospace, Precision Systems, and Ammunition. Sales, income from continuing operations before interest and income taxes, total assets, and other financial data for each of ATK's operating segments for the three years ended March 31, 2003 are set forth in Note 15 to the consolidated financial statements, included in Item 8 of this report.

        References in this report to a particular fiscal year are to the year ended March 31 of that calendar year.

        Many of ATK's products and programs are customarily referred to by customers or in the marketplace by acronyms. Many of these acronyms are included in this report (in parenthesis following the product or

2

program name) for the convenience of subsequent reference, and for the benefit of readers who may be more familiar with the acronyms than with the actual product or program names.

Aerospace

        The Aerospace operating segment supplies solid propulsion systems for commercial and government space launch vehicles, strategic missiles, and missile defense interceptors; and provides operations and technical support services for space launches. ATK has a broad product portfolio of solid propulsion rocket motors for space launch vehicles encompassing all vehicle payload classes, from small to heavy-lift. ATK supplies high-performance composite structures for space launch vehicles, rocket motor casings, military and commercial aircraft, and spacecraft structures. ATK also designs and manufactures composite structures, which are formed from high-strength carbon fibers and resin and have performance advantages over metal structures through weight reduction, fatigue resistance, and thermal stability. These advantages, coupled with improved design and analysis capabilities and manufacturing process technologies, continue to expand the markets and applications using these structures. Additionally, ATK designs and manufactures engineered reflectors and structures for satellite systems and high-temperature products for aerospace and commercial applications using ceramic matrix composites.

        The following table summarizes the principal programs in ATK's Aerospace operating segment, including identification of the customer and the ultimate end-user (an * indicates that the programs and products are currently in development):

        Civil Manned Space Launch Vehicles.    ATK is the sole manufacturer of the Space Shuttle Reusable Solid Rocket Motors (RSRM), which provide 80% of the initial thrust necessary for the National Aeronautics and Space Administration (NASA)'s Space Shuttle orbiters to reach orbit. A set of two RSRMs provides propulsion, in tandem with a liquid propulsion system, for the Space Shuttle. The RSRM uses a metal case and nozzle components that are recovered from the ocean after each flight. The metal cases and nozzle components are then cleaned, refurbished, and manufactured for reuse. ATK is currently under contract with NASA to provide RSRMs and other related services through May 2007. In fiscal 2003, the RSRM program represented 17% of ATK's total sales.

        As a result of the investigation of the Columbia failure and temporary suspension of Space Shuttle flights, NASA issued direction to ATK on June 3, 2003 to slow down the production rate of RSRM motor segments. NASA further states that ATK Thiokol should ensure that critical staffing skills be maintained. NASA indicated that as return to flight information is known, they will address returning to the regular RSRM motor production rate.

        ATK recognizes sales on the RSRM contract as costs are incurred. Prior to the Columbia accident, ATK had reached minimum staffing on the RSRM program. Therefore, any production slowdown is not expected to impact RSRM staffing. Metal case and nozzle hardware for the program have been purchased under prior contracts and are reused after each Space Shuttle flight. Expendable raw materials used in propellant manufacturing will be only minimally affected, and any reduction to raw materials quantities is expected to be partially offset by increased storage costs and materials pricing impacts. As such, ATK expects the slowdown to have minimal if any impact on fiscal 2004 sales.

        Unmanned Space Launch Vehicles.    ATK produces propulsion systems for some of the most significant space launch vehicle programs in the United States, including the Titan, Delta, and Atlas programs.

•

Titan Solid Rocket Motor Upgrades.    The solid rocket motor upgrade that provides the initial stage propulsion for Lockheed Martin's Titan IV B heavy-lift launch vehicle is used by the U.S. Air Force. ATK completed production on this program in early calendar year 2002. Two motors are used per launch. These motors have three composite case segments. ATK also has a contract for Titan launch operations support through September 2003 (with a proposed extension through April 2005) for inspection and oversight of solid rocket motor processing operations at the launch sites.



•

Graphite Epoxy Motors, or GEM.    The GEM series of propulsion systems are used as solid strap-on boosters for Boeing's Delta launch vehicle family, which consists of the Delta II, Delta III, and Delta IV vehicles. The Delta II is a medium-lift expendable launch vehicle developed for both government and commercial applications. The Delta II employs the GEM-40, a graphite epoxy motor measuring 40 inches in diameter. ATK also produces, under contract to Boeing, a larger strap-on GEM-46 booster for the enhanced medium-lift Delta III expendable launch vehicle. Boeing also awarded ATK a contract to develop and produce a new, even larger GEM-60 booster to be used with versions of the new Delta IV expendable launch vehicle. Delta II uses either three, four, or nine motors per launch; Delta III uses nine motors per launch; and the Delta IV Medium Plus vehicle uses either two or four motors per launch.

5

With a 40-year history, the Delta family of expendable launch vehicles has what is perhaps the most successful flight record of any rocket currently in service. Delta II has had 49 consecutive successful launches since January 1997. The Delta family has also launched into orbit the first passive communications satellite, ECHO, the first European satellite, Ariel 1, and the first communications satellite to reach geosynchronous orbit, Syncom 2.

•

CASTOR® Motors. The CASTOR® family of solid rocket motors are used in the first and second stages of a number of small payload expendable launch vehicles and as strap-on boosters. CASTOR 120® is used as the first stage on the Taurus® launch vehicle, the first stage on Athena I, and the first and second stage on Athena II launch vehicles. CASTOR® IV is used as strap-on thrust augmentation on the Atlas IIAS, with four motors used per launch. CASTOR IVA-XL motors are used as strap-on boosters on the Japanese H-IIA launch vehicles, with two or four motors used per launch. Taurus and Athena I and II are small payload launch vehicles, and Atlas IIAS and Japanese H-IIA are medium-lift vehicles. CASTOR® IVB is also used on the Maxus sounding rocket.



•

Orion Motors. Orion motors are used on the Pegasus®, Taurus®, and Minotaur launch vehicles. Pegasus® is a small-lift air-launched vehicle initially lifted by a conventional aircraft. Minotaur is a ground-launched vehicle for small payloads. Taurus® is a ground-launched vehicle for payloads larger than those that can be carried by Pegasus® and Minotaur. Pegasus® and Taurus® carry U.S. Government, foreign government, and commercial payloads. Minotaur carries only U.S. Government payloads. Each Pegasus® vehicle contains three solid propulsion stages, all produced by ATK. The three Pegasus® motors are also used in upper stages on Taurus® and two of the motors are used in upper stages on Minotaur. Minotaur also uses two refurbished motors from excess Minuteman strategic missiles.

        Strategic.    ATK provides propulsion systems for strategic missiles such as the Trident II and Minuteman, as well as those being proposed for Ground-based Midcourse Defense.

•

Intercontinental Ballistic Missiles.    Trident II is a submarine-launched intercontinental ballistic missile composed of three solid propulsion stages. ATK produces each of the three solid propulsion stages of this missile under a contract with Lockheed Martin. In addition to the Trident II production contract, ATK has contracts with Lockheed Martin to provide operational support services for the U.S. Navy's existing fleet of both Trident I and Trident II missiles.

Through a joint venture with Pratt & Whitney Space and Missile Propulsion of United Technologies Corporation, ATK produces replacement solid rocket motors for all three stages of Minuteman III, which is a silo-launched intercontinental ballistic missile. ATK also refurbishes excess Minuteman solid rocket motors for use as U.S. Air Force target vehicles. ATK developed and produced all first stage motors for the Peacekeeper and Minuteman I, II, and III missiles, and third stages for both the Peacekeeper and Minuteman II missiles for the U.S. Air Force and provides continuing aging studies and some operational support services for these missile systems.

•

Ground-based Midcourse Defense.    ATK is currently working as a motor supplier and subcontractor for the development and testing phase for multiple boost vehicle configurations of the U.S. Government's Ground-based Midcourse Defense ground-based interceptor for incoming ballistic missiles. ATK is developing a vectorable nozzle version of the Delta II GEM-40 booster for Lockheed Martin to be used as the first stage in one vehicle configuration and is under contract to Orbital Sciences for derivatives of the three Pegasus motors in a second boost vehicle configuration. ATK is well positioned to participate in all evolving configurations while spiral development and future deployment options are exercised over the next few years.

        Space Launch Vehicle Structures.    ATK is under contract with Boeing to produce composite structures for its Delta II, III, and IV family of expendable launch vehicles. For the Delta IV, ATK makes the common booster core nose cones, interstages, composite payload fairing, payload adapters, and other large

6

vehicle structures. ATK also produces large launch vehicle structure components for Lockheed Martin's Atlas V family of expendable launch vehicles, including interstages and a heat shield. Other launch vehicle structures being produced include the payload fairing for Pegasus®, and a payload adapter structure for Ariane V. ATK also produces composite cases for several solid rocket motors. Current programs include GEM motor cases for Delta II, III, and IV; Ground-based Midcourse Defense; Trident II first and second stage; and cases for motors used in Pegasus®, Taurus®, Athena, Minotaur, and Arrow II. ATK is developing low-cost, higher-performing launch structures technology under contract to the Air Force Research Laboratory.

•

Mid Range Munition (MRM). ATK is developing an extended range kinetic energy tank round for use by the U.S. Army's Future Combat System (FCS). This smart tank round incorporates a multi-mode seeker and advanced rocket motor to locate and destroy intended targets at beyond-line-of-sight ranges.



•

Autonomous Naval Support Round (ANSR). ATK is leading an industry team developing a ballistic trajectory, Global Positioning System (GPS) guided solution to U.S. Navy and U.S. Marine requirements for affordable, long-range, precise artillery. ANSR differs from other approaches in its simplicity and relatively low cost, as well as its application to various gun types and calibers. ANSR's application to the existing Navy inventory of 5"/54-caliber guns enables rapid introduction throughout the fleet, providing the Navy a break-through improvement in fire support capability.

12

•

Advanced Gun System Long Range Land Attack Projectile (AGS LRLAP). ATK is supporting Lockheed Martin Missiles and Fire Control with development and transition to production of the round's aft assembly that includes airframe, tail fin assembly, and rocket motor for this 155mm extended range guided projectile for the Advanced Gun System under development for DD(X).

        ATK has an agreement with GIWS, a joint venture between Rheinmetall W & M GmbH and Diehl Munitions System GmbH & Co. KG., to sell the SMArt 155® 155mm sensor fuzed munition in the United States and other countries. ATK estimates that future Army funding for a Sensor Fuzed Munition program appears likely in 2004 for inter-operability confirmation of the SMArt 155® system with follow-on production potential in 2006.

        In July 2002, ATK initiated internal funding for the development and pursuit of an Army Course Correction Module (2-D) for conventional 155mm artillery ammunition. ATK anticipates competitive Army funding in 2003 and 2004 for a technology demonstration program. Successful development would provide precision system accuracy for existing stocks of standard 155mm artillery ammunition.

        Missile Defense.    ATK is supplying all new propulsion elements for Raytheon's STANDARD Missile-3 (SM-3). SM-3 is a component of the U.S. Navy Aegis Ballistic Missile Defense System, slated for initial deployment in 2004 at President Bush's direction. ATK contributions include the Mk136 ASAS™-derived Third Stage Rocket Motor (TSRM) and the solid divert and attitude control system (SDACS) for the missile's Mk142 Kinetic Warhead (KW). The Mk136 TSRM is a dual-pulse rocket motor with integral thrust vector and attitude control systems. It provides the velocity required to track and engage the target. The SDACS provides the final lateral thrust to enable hit-to-kill intercepts.

        ATK is well positioned for emerging Missile Defense Agency boost phase intercept requirements, such as Kinetic Energy Interceptor, with its Advanced Solid Axial Stage (ASAS™) boosters. The ASAS™ booster family represents the result of significant government investment in advanced component technologies and manufacturing processes, along with ATK investment in motor demonstration tests. ATK is also developing technologies on programs such as the Miniature Kill Vehicle that will lower cost and enhance performance of future divert and attitude control systems.

        Missile Systems.    ATK is combining the missile system engineering capabilities it gained it its acquisition of Science and Applied Technologies, Inc. (SAT) in October 2002 with its traditional strengths in propulsion, warheads, and high volume manufacturing in the pursuit of key missile systems opportunities. Key current programs include:

•

AGM-88E Advanced Anti-Radiation Guided Missile (AARGM). AARGM is an innovative, multi-sensor, fuzed weapon system upgrade to the current generation AGM-88 High Speed Anti-radiation Missile (HARM). AARGM employs a multi-sensor guidance system capable of engaging enemy air defenses even after shut down of radar emissions. AARGM's multi-sensor fuzed design incorporates state-of-the-art passive and active radar systems that are integrated in a distributed architecture to provide enhanced performance and modular growth to meet evolving threat capabilities. ATK is in the process of transitioning this program to the System Development and Demonstration phase and anticipates low rate production by 2008.



•

Quick Bolt. The Quick Bolt program takes the baseline AARGM weapon system and adds features to enhance situational awareness and provide weapon impact assessment. With this capability, the weapon, while on the wing of the tactical aircraft, receives enemy target information in real time. This information is displayed in the cockpit and provides additional situational awareness to the pilot. After launch and just prior to impact, the weapon will transmit an encrypted, Weapon Impact Assessment (WIA) burst message back to national assets via its Quick Bolt transmitter, providing information regarding the weapon and target locations, and features about the target which it is about to destroy. The Quick Bolt Advanced Concept Technology Development (ACTD) program is

13

jointly funded by the U.S. Navy, Office of the Secretary of Defense's ACTD program office, and the National Reconnaissance Office.

•

High Speed Anti-radiation missile Demonstration (HSAD). ATK is under contract to provide the forebody (seeker, payload, and transition section) for the Office of Naval Research's demonstration program known as HSAD. This program is intended to develop and demonstrate a next-generation anti-radiation weapon that will fly twice the range of the current HARM at two to three times the average velocity. Ultimately, this weapon will provide the U.S. Navy the capability to prosecute enemy air defenses, command and control systems, and other time-critical targets from a safe, stand-off distance and will be deployable from all planned U.S. Navy tactical aircraft including the F/A-18C/D/E/F, the EA-6B and follow-on airplane, the JSF, and the Unmanned Combat Air Vehicle (UCAV).

        Tactical Rocket Motors and Warheads.    ATK designs, develops, and supplies solid propulsion systems and advanced warheads for tactical weapons used by the U.S. Army, U.S. Navy, and U.S. Air Force. These include air-to-air missiles, air-to-ground missiles, ground-to-ground missiles, and ground-to-air missiles.

•

The AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) is beginning Lot 16 of 24 planned production lots. In addition, rocket motors for the AIM-9X and AIM-9M Sidewinder and the AIM-7 Sparrow air intercept missiles are being produced. Technology development programs include next generation propulsion systems for AMRAAM and AIM-9X.



•

Air-to-Ground. Major production programs include the AGM-114 Hellfire II/Longbow and Brimstone rocket motors and warheads; all are anti-armor missiles fired from rotary wing and fixed wing aircraft. The Sensor Fuzed Weapon is used to neutralize land combat vehicles, defeating multiple targets from a single munitions dispenser. The AGM-65 Maverick is a general purpose air-to-ground missile. A technology development program is the Controllable Thrust for Common Missile, an advanced anti-armor missile.



•

Ground-to-Ground. ATK has been the U.S. Army's primary supplier of launch and flight motors for the TOW-2 (a tube launched, optically tracked, wire guided anti-tank missile) since the program's inception in 1981. ATK produces the propulsion for the Line-of-Sight Anti-Tank (LOSAT) missile, a high-speed kinetic energy missile used to defeat advanced armor systems. ATK is developing propulsion systems for the Predator, an integral launch and flight propulsion system for a shoulder launched anti-tank missile; Mongoose, a tractor motor for deploying a mine detonation net for advancement of combat vehicles on the battlefield; and Compact Kinetic Energy Missile (CKEM), a kinetic energy missile that will defeat advanced armor systems.



•

Surface-to-Air. Major production programs include the Evolved Sea Sparrow Missile (ESSM), a longer range version of the Sea Sparrow propulsion system; the RIM-7 Sparrow, the current medium range ship defense missile; and the rocket motor case for the MK112 RAM propulsion system, a short range ship defense missile.

        Space Stages.    The STAR™ family of motors are used as the upper stages for a variety of launch vehicles, for final positioning of satellites, or to propel a spacecraft beyond earth's orbit. These motors come in a wide variety of sizes (3 to 92 inch diameter) to meet a range of payload applications. STAR™ motors have a 40-year history with more than 3600 successful tests and flights and a 99.87% success rate. Integrated STAR™ stages combine proven STAR™ motors with attachment structures and a common avionics module to provide advanced upper stages that are ELV and Shuttle compatible. Most notably, STAR™ 48 motors serving as Delta II ELV upper stages and STAR™ 37FM motors used as spacecraft apogee kick motors (AKMs) have been used to deploy and maintain the USAF Global Positioning System (GPS). STAR™ motors are also under consideration for spiral evolution paths of the Ground-based Midcourse Defense system.

14

        Composite Structures.    ATK is the sole source producer of composite Javelin Launch Tubes, composite sabots for the M829A3 Tactical Round, and composite Pivot Shafts and By-Pass Screens for the F22 Aircraft.

        Soldier Weapon Systems.    XM29 is a lightweight, shoulder-fired dual weapon system designed to gradually replace select weapons of the Infantry Squad. The system consists of a combined weapon that fires both a high-explosive air-bursting munition with a smart fuze and a 5.56mm kinetic energy round and utilizes a full function fire control system including day optics, laser range finder, and thermal sights. ATK is responsible for development and systems integration of the weapon system and its family of ammunition. XM8 is the 5.56mm portion of the XM29 weapon being designed as a separable / stand-alone assault rifle with the primary focus on commonality with the XM29 system.

        Air Weapons.    Crash Pad, or BLU—119 / B, is a weapon that was delivered under an accelerated program with the Defense Threat Reduction Agency (DTRA) and the Air Force Research Laboratory (AFRL) to destroy / neutralize an enemy's access to weapons of mass destruction. The weapon consists of an improved MK-84 (2000 lb) munition loaded with a unique fill and a Joint Direct Attack Munition (JDAM) tail kit. ATK developed and flight-tested the new munition with DTRA and the U.S. Air Force in less than six months.

        Fuzes and Proximity Sensors.    ATK designs, develops, and supplies fuzes and proximity sensors for tactical weapons used by the U.S. Army, Navy, and Air Force. These include gun hardened and air armament fuzes.

•

Gun Hardened Fuzes. ATK's sole source fuze production programs include the safe and arming subsystem for the M734A1 fuze for mortar rounds. The safe and arming subsystem ensures that a round is armed and ready to fire only after it has met specific safety events during launch. ATK is also developing and has been awarded a Low Rate Initial Production contract for the U.S. Navy's Mk419 Multi-Function Fuze (MFF), which provides point detonation, delay, variable time, and proximity functions including air mode. ATK is developing the U.S. Army's Electronic Time Fuze for Mortars (ETFM). ATK is also under a multi-year contract to produce the M782 Artillery Multi-Option Fuze for Artillery (MOFA), which is the U.S. Army's next-generation, NATO-standard all-purpose artillery fuze for bursting munitions. It is inductively set to detonate by target proximity, time, delay after impact, or upon impact, and is operable with all existing and developmental 105mm and 155mm artillery systems.



•

Air Armament Fuzes. ATK is under contract to produce the DSU-33B/B proximity sensor for air-delivered bombs. This sensor allows a bomb to be detonated as it approaches the ground, thereby increasing the bomb's overall effectiveness. In addition, ATK has recently been awarded four contracts with U.S. allied nations for the production of the FMU-139 B/B bomb fuze and is currently producing in excess of 18,000 FMU-139 Accessory Kits for the U.S. Navy. ATK has a U.S. Air Force development contract for the Hard Target Smart Fuze (HTSF) and has been awarded the first two years of Pre-Production options. In addition, ATK is under contract to the U.S. Air Force to develop the next-generation hard target fuze, the Multiple Event Hard Target Fuze.

        Electronic Warfare Systems and Electronic Support Equipment.    ATK produces the AAR-47 missile warning system, a passive electro-optic threat warning device used to protect low, slow-flying helicopters, and fixed-wing aircraft by detecting ground-to-air-missiles. ATK completed qualification testing of the system that has upgraded sensors with laser warning detection along with enhanced software and central processor unit for improved probabilities of detection, longer warning times, and lower false alarm rates. ATK is currently in production on this system.

15

        ATK produces the Common Munitions BIT/Reprogramming Equipment, or CMBRE, which is a portable field tester/mission programmer with a common interface to support the growing U.S. inventory of smart weapons. Smart weapons provide mid-air guidance updates and can locate, track, and attack targets at extended range. Production of the Common Munitions BIT/Reprogramming Equipment is expected to continue beyond 2006.

        Barrier Systems.    ATK develops and produces advanced barrier systems. Primary production programs are the Volcano system, a modular barrier system delivered from ground and air platforms, and Shielder, a vehicle-launched smart anti-tank munition system. ATK has other international contracts and opportunities in this area. ATK also has contracts to develop the Anti-Personnel Land Mine Alternative program, or Spider, which is designed to be an integrated barrier system having operator command and control capabilities as an alternative to current potentially indiscriminate land mines and mine fields. This system is designed to provide an increased measure of operational effectiveness and minimize risks to friendly troops and civilians. ATK is a subcontractor on a team selected by the U.S. Government to develop the next-generation scatterable barrier system. ATK is at the forefront of high-technology barrier system development in the United States.

        Lithium and Lithium-ION Batteries.    ATK develops and manufactures specialized lithium batteries for U.S. and foreign military and aerospace customers. The principal lithium battery products are reserve batteries, which are used in such applications as anti-tank barriers, fuzes, and artillery systems that require long-term storage capacity. ATK has been awarded contracts for the U.S. Army's M767 and MOFA fuzes. ATK is developing a LI-ION Polymer Battery for the U.S. Navy's Advanced Sailor Delivery System (ASDS).

        Tank Ammunition.    ATK produces and develops a family of tactical and training tank rounds that is used by the Abrams tanks of the U.S. Army, Army Reserve, National Guard, U.S. Marines, and U.S. allies. Such rounds include the M830A1 multi-purpose round, the M829A3 kinetic energy round, and the M831A1 and M865 training rounds. ATK is the only producer of the M830A1 and M829A3 rounds. ATK is one of two suppliers to the U.S. Government for the M831A1 and M865 training rounds. ATK is currently under contract to the U.S. Army for development of the multi-purpose anti-tank training round for future training requirements. Some of the tank ammunition contains depleted uranium which is used for its armor penetrating qualities. Questions have been raised about the health and environmental effects of depleted uranium. ATK is also able to manufacture tank ammunition using alternatives to depleted uranium such as tungsten. As a result, ATK does not believe that a move by the U.S. Government or other customers away from the use of depleted uranium would have a material impact on ATK's results of operations or financial condition.

        Medium-Caliber Chain Guns.    ATK supplies medium-caliber gun systems to the U.S. military and allied nations. The ATK "chain gun" family of products provides greater operational safety, lethality, accuracy, and reliability than gas-powered guns. Their lighter weight and lower recoil make them desirable for rotary aircraft, light vehicle, and shipboard deck mount applications. ATK produces the 25mm M242 Bushmaster used by the U.S. Army for the Bradley Fighting Vehicle and by the U.S. Marines for the Light Armored Vehicle (LAV). The M242 has been integrated into many international vehicles for U.S. allies. Additionally, the 30/40mm Mk44 is used by the U.S. Marines for the Advanced Amphibious Assault Vehicle (AAAV) and is also in international production for U.S. allies. The 30mm M230 Chain Gun for the U.S. Army's AH-64 Apache and AH-64D Apache Longbow is also entering international production for naval patrol applications. ATK also performs maintenance, refurbishment, and logistic support services for its chain guns in support of the U.S. military and its allies.

16

        Medium-Caliber Ammunition.    ATK is a leading supplier of medium-caliber ammunition and fuzes and produces, designs, and develops medium-caliber ammunition for the U.S. military and U.S. allies. Production programs include:

•

Programs include a new mechanically fuzed family of ZAP ammunition (20mm to 30mm) for delayed initiation applications and a new electromechanically fuzed family of ammunition for air burst applications. ATK has delivered initial contract quantities of the ZAP rounds to the U.S. Air Force, U.S. Navy and U.S. Marines. ATK has also conducted a live fire demonstration for the Army (PM—Maneuver Ammunition Systems) and the Marines (AAAV Program Office) from both a Bradley Fighting Vehicle configuration and a Bushmaster II ground mount that illustrated the accuracy and repeatability of the electromechanical (turns/time) fuze for Air Burst Munition (ABM) applications.

Ammunition

        The Ammunition operating segment supplies small-caliber military ammunition, ammunition and rocket propellants, commercial and military smokeless powder, law enforcement and sporting ammunition, and ammunition-related products.

        The following table summarizes the principal programs in ATK's Ammunition operating segment, including identification of the customer and the ultimate end-user:

17

        Small-Caliber Ammunition.    ATK manufactures and develops small-caliber ammunition for the U.S. military, U.S. allies, federal and local law enforcement agencies, and commercial markets. ATK produced approximately 800 million rounds of ammunition in fiscal 2003 for the U.S. military and U.S. allies, consisting of .22 caliber, .45 caliber, 5.56mm, 7.62mm, .30 caliber, and .50 caliber cartridges. ATK also manufactures metal links for belting of all sizes of ammunition, ranging from 5.56mm rifle ammunition to 40mm grenades.

        ATK's small-caliber ammunition operations for the U.S. military and U.S. allies are conducted at the Lake City Army Ammunition Plant in Independence, Missouri, which supplies over 95% of the Army's small-caliber ammunition needs. Lake City is the Army's only small-caliber ammunition production facility. ATK took over operation of this facility on April 1, 2000 and is responsible for managing it, including leasing excess space to third parties in the private sector. ATK has a 10-year production contract to supply the Army's small-caliber ammunition needs that expires in April 2010. ATK also has a facilities-use contract for the plant that expires in April 2025. Although the facilities-use contract expires 15 years after the plant production contract, were the plant production contract not renewed, ATK believes the U.S. Army would relieve ATK of all of its obligations under the facilities-use contract.

        In addition to production, ATK performs research and development for military ammunition and ammunition manufacturing and supports the Army Research Development Engineering Center at Picatinny Arsenal, New Jersey for Department of Defense sponsored product design, development, and testing. ATK is currently under contract to the U.S. Government for production quantities of 5.56mm ammunition incorporating lead-free projectiles, or "green" ammunition, and expects it will be phased into use over the next several years as a substitute for ammunition that contains lead.

        ATK also manufactures small-caliber ammunition for federal and local law enforcement agencies and commercial markets. Principal products in the civil ammunition business include ammunition for shotguns, pistols, and rifles, and industrial power loads for the construction industry. These ammunition products are marketed under a number of well-known brand names including Federal (Premium, Gold Medal, Classic, and American Eagle), CCI, Speer (Gold Dot and Blazer), and Estate Cartridge. These products are well known in their respective markets and are recognized for their quality by law enforcement officials and shooting sports enthusiasts. These products are distributed via mass merchants, specialty sporting equipment stores, specialty sporting equipment distributors, law enforcement agencies, and government agencies.

        Solid Extruded Propellants.    ATK manufactures, designs, and develops solid extruded propellants for use in over 25 types of ammunition and rockets used by the U.S. military services. ATK also loads, assembles, and packs 155mm artillery propelling charges.

        Primary production programs include propellants for multiple training and war reserve 120mm tank rounds, the modular artillery charge system, and 25mm and 30mm ammunition. ATK is also the only supplier to the U.S. Government of Mk-90 propellant grains for use in the Hydra 70 missile and launch motors for the Tube-launched, Optically-tracked, Wire-guided (TOW-2) missile. ATK is a major producer

18

of several types of smokeless nitrocellulose, which is a primary ingredient in the manufacturing of ammunition propellants and powders. In addition to the military programs, ATK produces a wide range of commercial gun powders for manufacturers of sporting ammunition and reloaders, who make their own ammunition by refilling previously-fired cartridge casings.

        Propellant development opportunities being pursued include next-generation 2.75" rocket propellant grain, environmentally-friendly propellant, and propellant for advanced artillery charges.

        Commercial Accessories.    ATK manufactures reloading equipment, gun care products, and other accessories. Principal products in the accessories operations include reloading equipment for use by hunters and sportsmen who prefer to reload their own ammunition, gun care products and accessories, and trap-shooting products. These products are sold under well-known brand names, including RCBS, Outers, Champion Target, Weaver, Redfield, and Simmons; are distributed via mass merchants, specialty sporting equipment stores, and specialty sporting equipment distributors; and have leading market shares in their respective product categories.

Major Customers

        ATK's sales are predominantly derived from contracts with agencies of the U.S. Government and its prime contractors and subcontractors. The various U.S. Government customers, which include the U.S. Army, the National Aeronautics and Space Administration (NASA), the U.S. Air Force, and the U.S. Navy, exercise independent purchasing power. As a result, sales to the U.S. Government generally are not regarded as constituting sales to one customer; instead, each contracting customer entity is considered a separate customer.

        The following table summarizes the approximate percentage breakdown of all fiscal 2003 sales to various categories of customers:

        ATK's U.S. Government sales, including sales to U.S. Government prime contractors, during the last three fiscal years are summarized in the following table:

        This significant reliance upon contracts related to U.S. Government programs entails inherent benefits and risks, including those particular to the defense and aerospace industry. ATK derived approximately 17% of its total sales in fiscal 2003 from the reusable solid rocket motor contract with NASA. No other single contract contributed more than 10% of ATK's sales in fiscal 2003. ATK's top five contracts accounted for approximately 38% of fiscal 2003 net sales.

19

        The following table summarizes the approximate percentage breakdown of fiscal 2003 sales to the U.S. Government as a prime contractor and a subcontractor:

        No single customer, other than the U.S. Government customers listed above, accounted for more than 10% of ATK's fiscal 2003 sales.

        Approximately 7.5% of fiscal 2003 sales were to foreign governments and corporations, which must be approved by the Department of Defense and the State Department. Approximately 63% of these sales are in the Precision Systems segment, 28% are in the Ammunition segment, and 9% are in the Aerospace segment. These products are sold both directly and through the U.S. Government to U.S. allies. Foreign sales for each of the last three fiscal years are summarized below:

        Major law enforcement customers include the New York City Police Department, the Federal Bureau of Investigation, and the U.S. Secret Service. Major customers of the civil ammunition business include retailers, including Wal-Mart, as well as major wholesale distributors.

Risk Factors

        ATK is subject to a number of risks, including those related to being a U.S. Government contractor. Some of the risks facing ATK are discussed below.

ATK's business could be adversely impacted by reductions or changes in U.S. Government military spending.

        As the majority of ATK's sales are to the U.S. Government and its prime contractors, ATK depends heavily on the contracts underlying these programs. Also, a significant portion of ATK's sales come from a small number of contracts. ATK's top five contracts, all of which are contracts with the U.S. Government, accounted for approximately 38% of fiscal 2003 sales. Although ATK expects the U.S. defense budget to continue to increase over the next five years, future levels of defense spending cannot be predicted with certainty. The loss or significant reduction of a material program in which ATK participates could have a material adverse effect on ATK's operating results, financial condition, or cash flows.

        U.S. Government contracts are also dependent on the continuing availability of Congressional appropriations. Congress usually appropriates funds for a given program on a fiscal year basis even though contract performance may take more than one year. As a result, at the outset of a major program, the contract is usually incrementally funded, and additional monies are normally committed to the contract by the procuring agency only as appropriations are made by Congress for future fiscal years. In addition, most U.S. Government contracts are subject to modification if funding is changed. Any failure by Congress to appropriate additional funds to any program in which ATK participates, or any contract modification as a result of funding changes, could materially delay or terminate the program. This could have a material adverse effect on ATK's operating results, financial condition, or cash flows.

ATK may not be able to react to increases in its costs due to the nature of its U.S. Government contracts.

        ATK's U.S. Government contracts can be categorized as either "cost-plus" or "fixed-price."

20

        Cost-Plus Contracts.    Cost-plus contracts are either cost-plus-fixed-fee, cost-plus-incentive-fee, or cost-plus-award-fee contracts. Cost-plus-fixed-fee contracts allow ATK to recover its approved costs plus a fixed fee. Cost-plus-incentive-fee contracts and cost-plus-award-fee contracts allow ATK to recover its approved costs plus a fee that can fluctuate based on actual results as compared to contractual targets for factors such as cost, quality, schedule, and performance.

        Fixed-Price Contracts.    Fixed-price contracts are either firm-fixed-price, fixed-price-incentive, or fixed-price-level-of-effort contracts. Under firm-fixed-price contracts, ATK agrees to perform certain work for a fixed price and absorb any cost underruns or overruns. Fixed-price-incentive contracts are fixed-price contracts under which the final contract prices may be adjusted based on total final costs compared to total target cost, and may be affected by schedule and performance. Fixed-price-level-of-effort contracts allow for a fixed price per labor hour, subject to a contract cap. All fixed-price contracts present the inherent risk of unreimbursed cost overruns, which could have a material adverse effect on operating results, financial condition, or cash flows. The U.S. Government also regulates the accounting methods under which costs are allocated to U.S. Government contracts.

        The following table summarizes how much each of these types of contracts contributed to ATK's U.S. Government business in fiscal 2003:

Contracts are subject to termination.

        The U.S. Government may terminate its contracts with its suppliers, either for its convenience or in the event of a default by the contractor. If a cost-plus contract is terminated, the contractor is entitled to reimbursement of its approved costs. If the termination is for convenience, the contractor is also entitled to receive payment of a total fee proportionate to the percentage of the work completed under the contract. If a fixed-price contract is terminated, the contractor is entitled to receive payment for items delivered to and accepted by the U.S. Government. If the termination is for convenience, the contractor is also entitled to receive fair compensation for work performed plus the costs of settling and paying claims by terminated subcontractors, other settlement expenses, and a reasonable profit on the costs incurred or committed. If a contract termination is for default:

•

the contractor is paid an amount agreed upon for completed and partially completed products and services accepted by the U.S. Government;



•

the U.S. Government is not liable for the contractor's costs for unaccepted items, and is entitled to repayment of any advance payments and progress payments related to the terminated portions of the contract; and



•

the contractor may be liable for excess costs incurred by the U.S. Government in procuring undelivered items from another source.

ATK is subject to procurement and other related laws and regulations, non-compliance with which may expose ATK to adverse consequences.

        ATK is subject to extensive and complex U.S. Government procurement laws and regulations, along with ongoing U.S. Government audits and reviews of contract procurement, performance, and administration. ATK could suffer adverse consequences if it were to fail to comply, even inadvertently, with these laws

21

and regulations or with laws governing the export of munitions and other controlled products and commodities; or commit a significant violation of any other federal law. These consequences could include contract termination; civil and criminal penalties; and under certain circumstances, ATK's suspension and debarment from future U.S. Government contracts for a specified period of time. In addition, foreign sales are subject to greater variability and risk than ATK's domestic sales. Foreign sales subject ATK to numerous stringent U.S. and foreign laws and regulations, including regulations relating to import-export control, repatriation of earnings, exchange controls, the Foreign Corrupt Practices Act, and the anti-boycott provisions of the U.S. Export Administration Act. Failure to comply with these laws and regulations could result in material adverse consequences to ATK.

Novation of U.S. Government contracts involves risk.

        When U.S. Government contracts are transferred from one contractor to another, such as in connection with the sale of a business, the U.S. Government may require that the parties enter into a novation agreement. A novation agreement generally provides that:

•

the transferring contractor guarantees or otherwise assumes liability for the performance of the acquiring contractor's obligations under the contract;



•

the acquiring contractor assumes all obligations under the contract; and



•

the U.S. Government recognizes the transfer of the contract and related assets.

        ATK has completed novation agreements covering U.S. Government contracts acquired in the Hercules Aerospace Company, Boeing Ordnance, and Science and Applied Technology, Inc. acquisitions. These novation agreements provide that ATK assumes all obligations under the acquired contracts and that the U.S. Government recognizes the transfers to ATK of the acquired contracts and related assets. Under each novation agreement, the acquired contracts are scheduled to be performed over time, and it is not expected that they will be fully and finally discharged for several years. Under each novation agreement, the seller of the respective assets has agreed to indemnify ATK against any liability that ATK may incur under the novation agreement caused by any prior failure by the seller to perform its obligations under its respective novated contracts. ATK has agreed to indemnify the seller against any liability that the seller may incur under the novation agreement caused by any failure by ATK to perform its obligations under the novated contracts.

        ATK was not required to novate the U.S. Government contracts acquired in the Thiokol acquisition because ATK acquired Cordant's stock, rather than the assets of the business. ATK has provided the U.S. Government with a corporate guarantee that its obligations under the contracts will be fulfilled. ATK did not acquire any U.S. Government contracts that required novation in the acquisition of the civil ammunition business. ATK was not required to novate the U.S. Government contracts acquired in the Composite Optics, Inc. (COI) acquisition because ATK acquired COI's stock, rather than the assets of the business.

Other risks associated with U.S. Government contracts may expose ATK to adverse consequences.

        In addition, like all U.S. Government contractors, ATK is subject to risks associated with uncertain cost factors related to:

•

scarce technological skills and components;



•

the frequent need to bid on programs in advance of design completion, which may result in unforeseen technological difficulties and/or cost overruns;



•

the substantial time and effort required for design and development;



•

design complexity;



•

rapid obsolescence; and



•

the potential need for design improvement.

22

ATK is subject to intense competition and therefore may not be able to compete successfully.

        ATK encounters competition for most contracts. Some of these competitors have substantially greater financial, technical, marketing, manufacturing, distribution, and other resources. ATK's ability to compete for these contracts depends to a large extent upon:

•

its effectiveness and innovativeness of research and development programs;



•

its ability to offer better program performance than the competitors at a lower cost;



•

its readiness with respect to facilities, equipment, and personnel to undertake the programs for which it competes; and



•

its past performance and demonstrated capabilities.

        In some instances, the U.S. Government directs a program to a single supplier. In these cases, there may be other suppliers who have the capability to compete for the programs involved, but they can only enter or reenter the market if the U.S. Government chooses to open the particular program to competition. ATK's sole-source contracts accounted for 61% of U.S. Government sales in fiscal 2003 and include the following programs: reusable solid rocket motor (RSRM) Space Shuttle boosters, Trident II missiles, Minuteman III Propulsion Replacement Program, Titan IV solid rocket motor upgrade space boosters, Advanced Medium-Range Air-to-Air Missile (AMRAAM), Hellfire, Sensor Fuzed Weapon propulsion systems, M830A1 multi-purpose tank ammunition rounds, Volcano anti-tank scatterable barriers, M758 fuze for medium-caliber ammunition, the AAR-47 missile warning system, Javelin launch tubes, M829A3 tank ammunition, Solid Divert and Attitude Control Systems and Third Stage Rocket Motors (SDACS/TSRM), STAR™ Motors, and Advanced Anti-Radiation Guided Missile (AARGM).

        In the commercial ammunition and accessories markets, ATK competes against manufacturers that have well-established brand names and strong market positions.

        ATK generally faces competition from a number of competitors in each business area, although no single competitor competes along all three of ATK's operating segments. ATK's principal competitors in each of its operating segments are as follows:

        Aerospace: Pratt & Whitney Space and Missile Propulsion of United Technologies Corporation; Aerojet-General Corporation, a subsidiary of GenCorp Inc.; Atlantic Research Corporation, a subsidiary of Sequa Corporation; The Boeing Company; Lockheed Martin Corporation; Raytheon Company; Bell Helicopter Textron, a subsidiary of Textron Inc.; Northrop Grumman Corporation; Applied Aerospace Structures Corporation; Programmed Composites Inc., a division of Pressure Systems, Inc.; GKN plc; Aurora Bearing Company; AAR Corp.; Ducommun Incorporated; Marion and Lincoln Composites, both subsidiaries of General Dynamics Corporation; Vought Aircraft Industries, Inc.; and Goodrich Corporation.

        Precision Systems: General Dynamics Ordnance and Tactical Systems, Inc., (GD-OTS) a subsidiary of General Dynamics Corporation; Raytheon Company; Textron Inc.; L3/KDI; L3/Bulova Technologies; and Giat Industries S.A.

        Ammunition: GD-OTS; Winchester Ammunition of Olin Corporation; Remington; and various importers, including P.M.C., Fiocchi, and Selliers & Belloitt.

        The downsizing of the munitions industrial base has resulted in a reduction in the number of competitors through consolidations and departures from the industry. This has reduced the number of competitors for some programs, but has strengthened the capabilities of some of the remaining competitors. In addition, it is possible that there will be increasing competition from the remaining competitors in business areas where they do not currently compete, particularly in those business areas dealing with electronics.

23

Disruptions in the supply of key raw materials and difficulties in the supplier qualification process could adversely impact ATK.

        Key raw materials used in ATK's operations include aluminum, steel, steel alloys, copper, brass, lead, graphite fiber, prepreg, hydroxy terminated polybutadiene, epoxy resins and adhesives, ethylene propylene diene monomer rubbers, nitrocellulose, diethylether, x-ray film, plasticizers and nitrate esters, impregnated ablative materials, various natural and synthetic rubber compounds, polybutaadiene, acrylonitrile, and ammonium perchlorate. ATK also purchases chemicals; electronic, electro-mechanical and mechanical components; subassemblies; and subsystems which are integrated with the manufactured parts for final assembly into finished products and systems.

        ATK closely monitors sources of supply to assure that adequate raw materials and other supplies needed in manufacturing processes are available. As a U.S. Government contractor, ATK is frequently limited to procuring materials and components from sources of supply approved by the U.S. Department of Defense (DoD). In addition, as business conditions, the DoD budget, and Congressional allocations change, suppliers of specialty chemicals and materials sometimes consider dropping low volume items from their product lines, which may require, as it has in the past, qualification of new suppliers for raw materials on key programs. The supply of ammonium perchlorate, a principal raw material used in ATK's operations, is limited to a single source that supplies the entire domestic solid propellant industry. This single source, however, maintains two separate manufacturing lines a reasonable distance apart, which mitigates the likelihood of a fire, explosion, or other problem impacting all production. ATK also presently relies on one primary supplier for graphite fiber, which is used in the production of composite materials. This supplier has multiple manufacturing lines for graphite fiber. Although other sources of graphite fiber exist, the addition of a new supplier would require ATK to qualify the new source for use.

        Current suppliers of some insulation materials used in rocket motors have announced plans to close manufacturing plants and discontinue product lines. These materials include polymers used in ethylene propylene diene monomer rubber insulation and aerospace grade rayon used in nozzles. ATK has qualified new replacement materials for certain programs. For other programs, ATK has produced sufficient inventory to cover program requirements through 2004 and is in the process of qualifying new replacement materials. ATK expects these new materials to be qualified in time to meet future production needs.

        Prolonged disruptions in the supply of any of ATK's key raw materials, difficulty completing qualification of new sources of supply, or implementing use of replacement materials or new sources of supply could have a material adverse effect on ATK's operating results, financial condition, or cash flows.

Due to the volatile and flammable nature of its products, fires or explosions may disrupt ATK's business.

        Many of ATK's products involve the manufacture and/or handling of a variety of explosive and flammable materials. From time to time, these activities have resulted in incidents which have temporarily shut down or otherwise disrupted some manufacturing processes, causing production delays and resulting in liability for workplace injuries and fatalities. ATK has safety and loss prevention programs which require detailed pre-construction reviews of process changes and new operations, along with routine safety audits of operations involving explosive materials, to mitigate such incidents, as well as a variety of insurance policies. However, ATK cannot ensure that it will not experience similar incidents in the future or that any similar incidents will not result in production delays or otherwise have a material adverse effect on its results of operations, financial condition, or cash flows.

ATK is subject to environmental rules and regulations, non-compliance with which may expose ATK to adverse consequences.

        ATK's operations and ownership or use of real property are subject to a number of federal, state, and local environmental laws and regulations. At certain sites, there is known or potential contamination that ATK is required to investigate or remediate. ATK could incur substantial costs, including remediation

24

costs, fines, and penalties, or third party property damage or personal injury claims, as a result of violations or liabilities of environmental laws or non-compliance with environmental permits.

        ATK expects that a portion of its environmental compliance and remediation costs will be recoverable under U.S. Government contracts. Some of the remediation costs that are not recoverable from the U.S. Government that are associated with facilities purchased in a business acquisition may be covered by various indemnification agreements. As part of its acquisition of the Hercules Aerospace Company, ATK assumed responsibility for environmental compliance at the facilities acquired from Hercules (the Hercules Facilities). ATK believes that a portion of the compliance and remediation costs associated with the Hercules Facilities will be recoverable under U.S. Government contracts, and that those environmental remediation costs not recoverable under these contracts will be covered by Hercules Incorporated (Hercules) under environmental agreements entered into in connection with the Hercules acquisition. Under these agreements, Hercules has agreed to indemnify ATK for environmental conditions relating to releases or hazardous waste activities occurring prior to ATK's purchase of the Hercules Facilities; fines relating to pre-acquisition environmental compliance; and environmental claims arising out of breaches of Hercules's representations and warranties. Hercules is not required to indemnify ATK for any individual claims below $50,000. Hercules is obligated to indemnify ATK for the lowest cost response of remediation required at the facility that is acceptable to the applicable regulatory agencies. ATK is not responsible for conducting any remedial activities with respect to the Kenvil, NJ facility or the Clearwater, FL facility. Hercules' environmental indemnity obligation relating to contamination on federal lands remains effective, provided that ATK gives notice of any claims related to federal lands on or before December 31, 2005.

        One of the Hercules Facilities is ATK's Bacchus facility in Magna, Utah. In December 2001, ATK received notice from the State of Utah of a potential claim against ATK under Section 107(f) of CERCLA for natural resource damages at Bacchus. The notice letter, which was issued to preserve the State's rights under CERCLA, also expressly acknowledged the State's willingness to allow ATK to go forward with its currently-planned monitoring and remediation program. The State's preliminary estimate of damages contained in this claim was $139 million, which is based on known and alleged groundwater contamination at and near Bacchus and is related to Hercules' manufacturing operations at the site. ATK has had discussions with the State regarding this claim and entered into a tolling agreement with the State in fiscal 2002. In fiscal 2003, ATK entered into a similar tolling agreement with the State regarding the Promontory facility that was acquired from Alcoa in the acquisition of Thiokol. These agreements effectively defer the bringing of any potential claim against ATK by the State for a period of at least 10 years. They allow ATK time to continue to identify and address the contamination by the normal and planned regulatory remediation processes in Utah. Although ATK has previously made accruals for its best estimate of the probable and reasonably estimable costs related to the remediation obligations known to ATK with respect to the affected areas, ATK cannot yet predict if or when a suit may be filed against it, nor can ATK determine any additional costs that may be incurred in connection with this matter.

        Under the Thiokol purchase agreement, ATK generally assumed responsibility for environmental compliance at the acquired facilities. While ATK expects that a portion of the compliance and remediation costs associated with the acquired Thiokol Facilities will be recoverable under U.S. Government contracts, ATK has recorded an accrual to cover those environmental remediation costs at these facilities that will not be recovered through U.S. Government contracts. ATK is responsible for any costs not recovered through U.S. Government contracts at Thiokol Facilities up to $29 million; ATK and Alcoa have agreed to split evenly any amounts between $29 million and $49 million, subject to ATK having appropriately notified Alcoa of any issues prior to January 30, 2004; and ATK is responsible for any payments in excess of $49 million.

        With respect to the facilities purchased from Blount, Blount has agreed to indemnify ATK for certain compliance and remediation liabilities, to the extent those liabilities are related to pre-closing environmental conditions at or related to these facilities. Some other remediation costs are expected to be paid directly by a third party pursuant to an existing indemnification agreement with Blount. Blount's indemnification

25

obligations relating to environmental matters, which extend for five years following closing, are capped at $30 million, less any other indemnification payments made for breaches of representations and warranties. The third party's obligations, which extend through November 4, 2007, are capped at approximately $125 million, less payments previously made.

        ATK also has an indemnification agreement from The Boeing Company in connection with the facilities of ATK Gun Systems.

        ATK cannot ensure that the U.S. Government, Hercules, Alcoa, Blount, or other third parties will reimburse it for any particular environmental costs or reimburse ATK in a timely manner or that any claims for indemnification will not be disputed. U.S. Government reimbursements for cleanups are financed out of a particular agency's operating budget and the ability of a particular governmental agency to make timely reimbursements for cleanup costs will be subject to national budgetary constraints. ATK's failure to obtain full or timely reimbursement from the U.S. Government, Hercules, Alcoa, Blount, or other third parties could have a material adverse effect on its operating results, financial condition, or cash flows. While ATK has environmental management programs in place to mitigate these risks, and environmental laws and regulations have not had a material adverse effect on ATK's operating results, financial condition, or cash flows in the past, it is difficult to predict whether they will have a material impact in the future.

Backlog

        Total backlog, which includes the estimated value of contracts awarded to ATK but for which revenue has not yet been recognized, plus the value of unexercised options, was $5.2 billion as of March 31, 2003, compared to $5.6 billion as of March 31, 2002. The decrease in backlog during fiscal 2003 results primarily from the NASA reusable solid rocket motor (RSRM) program. The current RSRM contract extends through May 2007. RSRM backlog will continue to decline over this time frame until a follow-on contract is executed.

        ATK expects that approximately 66% of fiscal 2004 sales will fill orders that were in backlog at April 1, 2003.

Research and Development

        ATK conducts a significant amount of research and development. Company-funded research and development is primarily for the development of next-generation technology. Customer-funded research and development primarily represents research and development efforts that ATK undertakes under contracts with the U.S. Government and its prime contractors. The following table summarizes research and development expenditures in each of the last three fiscal years:

Seasonality

        Sales of sporting ammunition are significantly higher in ATK's second and third fiscal quarters. ATK's other business is generally not seasonal in nature.

Employees

        As of March 31, 2003, ATK employed approximately 12,000 employees. Approximately 15% of these employees were covered by collective bargaining agreements. The following table summarizes the number

26

of these agreements, the expiration dates of the agreements, and the approximate number of employees represented.

        Relations between ATK and unionized and non-unionized employees and their various representatives are generally considered satisfactory. However, ATK cannot ensure that new labor contracts can be agreed to without work stoppages and resultant adverse financial impacts.

Patents

        As of March 31, 2003, ATK owned approximately 500 U.S. patents and 400 foreign patents and had approximately 150 U.S. patent applications and 300 foreign patent applications pending. Although the conduct of ATK's business involves the manufacture of various products that are covered by patents, ATK does not believe that any one single existing patent or license or group of patents is material to the success of the business as a whole. ATK believes that unpatented research, development, and engineering skills also make an important contribution to its business. The U.S. Government typically receives royalty-free licenses to inventions made under U.S. Government contracts, under which ATK retains all other rights, including all commercial rights, to such inventions. In addition, ATK's policy is to protect proprietary information from unauthorized disclosure, consistent with which, ATK ordinarily requires employees to sign confidentiality agreements as a condition of employment.

Captive Insurance Subsidiary

        Alliant Assurance Ltd. (Assurance) is a wholly-owned subsidiary of ATK. Assurance was organized to provide insurance and reinsurance for the property and liability risks of ATK. The various types of insurance coverage provided includes property damage and business interruption risks, excess liability, and general liability risks. In addition, Assurance has assumed specific liabilities of ATK for environmental remediation and post-retirement medical and life insurance benefits. For certain of these liabilities, reserves for policy claims are established based on actuarial projections of ultimate losses.

ITEM 2.    PROPERTIES

        As of March 31, 2003, ATK occupied manufacturing, assembly, warehouse, test, research, development, and office properties having a total floor space of approximately 17.7 million square feet. These properties are either owned or leased, or are occupied under facilities-use contracts with the U.S. Government. The following table provides summary information about the location and size of these properties, and indicates which operating segment is the principal user of the property—Aerospace ("Ae"), Precision Systems ("PS"), or Ammunition ("Am"). In some cases, property is used by more than one operating segment.

(1)

These properties are occupied rent-free under facilities contracts that require ATK to pay for all utilities, services, and maintenance costs.

28

(2)

The Edina facility is ATK's corporate headquarters.

(3)

Operating segment usage of these properties is as follows (in thousands of square feet): Aerospace 7,617; Precision Systems 2,481; and Ammunition, 7,953.

(4)

Principally sales and other offices, each of which has less than 10,000 square feet of floor space.

        The following table provides summary information about the location, size, and use of other owned or leased land, and indicates which operating segment is the principal user of the land:

        ATK personnel also occupy space at the following facilities that are not owned by ATK: Marshall Space Flight Center, Huntsville, AL; Kennedy Space Center, Cape Canaveral, FL; Vandenburg Air Force Base, Vandenburg, CA; and Picatinny Arsenal, Picatinny, NJ.

        ATK's properties are well maintained and in good operating condition and are sufficient to meet ATK's near-term operating requirements.

ITEM 3.    LEGAL PROCEEDINGS

        From time to time, ATK is subject to various legal proceedings, including lawsuits, which arise out of, and are incidental to, the conduct of ATK's business. ATK does not consider any of such proceedings, individually or in the aggregate, to be material to its business or likely to result in a material adverse effect on its future operating results, financial condition, or cash flows.

        U.S. Government Investigations.    ATK is also subject to U.S. Government investigations from which civil, criminal, or administrative proceedings could result. Such proceedings could involve claims by the U.S. Government for fines, penalties, compensatory and treble damages, restitution, and/or forfeitures. Under government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, or lose its export privileges, based on the results of investigations. ATK believes, based upon all available information, that the outcome of any such government investigations will not have a material adverse effect on its operating results, financial condition, or cash flows.

        Environmental Remediation.    ATK's operations and ownership or use of real property are subject to a number of federal, state, and local laws and regulations, including those for discharge of hazardous materials and remediation of contaminated sites. Due in part to their complexity and pervasiveness, such laws and regulations have resulted in ATK being involved with a number of related legal proceedings, claims, and remediation obligations. ATK routinely assesses, based on in-depth studies, expert analyses, and legal reviews, its contingencies, obligations, and commitments for remediation of contaminated sites, including assessments of ranges and probabilities of recoveries from other responsible parties. ATK's policy is to accrue and charge to expense in the current period any identified exposures related to

29

environmental remediation sites based on estimates of investigation, cleanup, and monitoring costs to be incurred.

        ATK could incur substantial costs, including cleanup costs, fines, and penalties or third-party property damage or personal injury claims, as a result of violations or liabilities under environmental laws or non-compliance with environmental permits. While environmental laws and regulations have not had a material adverse effect on ATK's operating results, financial condition, or cash flows in the past, and ATK has environmental management programs in place to mitigate these risks, it is difficult to predict whether they will have a material impact in the future.
