Exhibit 99.2

CEO Update: 4/29/14 – A New Day for ATK

Creating Two Standalone Companies

This morning, ATK announced that our Board of Directors unanimously approved the creation of two independent, publicly traded companies through the tax-free spin-off of our Sporting Group (Sporting) and a merger between Orbital Sciences Corporation (Orbital) and our Aerospace and Defense Groups (ATK A&D).

In line with our Vision & Strategy to create leadership positions in all of our core markets – aerospace, defense and sporting – this plan will deliver value to our shareholders and customers, and new opportunities for our employees.

ATK is well-positioned and ready to create two strong enterprises focused on our core capabilities and long-term growth strategies. This transaction allows our Sporting business and our Aerospace and Defense businesses to be more focused in their respective markets and take advantage of growth opportunities. Today, our Sporting and A&D businesses operate in fundamentally different segments with different strategies, operating dynamics, and compliance requirements. This transaction will enable us to broaden and deepen our market leadership and focus on our unique capabilities and inherent strengths.

Spin-off

ATK’s Sporting Group is a world leader in ammunition, accessories and firearms for hunting, shooting, outdoor enthusiasts, and law enforcement professionals. Our recent acquisitions of Savage and Bushnell have increased our exposure to new and adjacent markets, enabling us to successfully deliver a broad portfolio of brands, increased product innovation, and enhanced sourcing and distribution. I am excited for the future and the opportunity to create a focused, commercial sporting company that is positioned as a world leader in the outdoor recreation market.

ATK entered the commercial ammunition business with the acquisition of Blount International in 2001. In a little more than a decade, our investments, customer focus, and execution excellence have propelled us into the world’s largest shooting sports and outdoor company.

ATK shareholders will own 100 percent of the shares of the new, publicly traded Sporting company after a proposed tax-free distribution. Sporting will have a strong balance sheet that will support future growth and support the expansion of our capabilities and product offerings.

The company’s headquarters will be in Utah, and I look forward to serving as the Chairman and Chief Executive Officer (CEO) of Sporting. Additional details, including the company name and brand, are being determined and will be shared with you as appropriate. Currently, about 5,800 employees work in the Sporting Group, and we have a footprint in 11 of the United States, Canada, Mexico, Puerto Rico, Europe and Asia.

Merger

ATK A&D will combine with Orbital in a tax-free, all-stock merger, with Orbital becoming a wholly owned subsidiary of ATK. Upon completion of the transaction, ATK will change its name to Orbital ATK, Inc. (Orbital ATK), and ATK shareholders will own 53.8 percent in the combined company, with Orbital shareholders owning the remaining 46.2 percent. Both companies’ boards of directors approved the definitive agreement.

Orbital’s co-founder, Chairman, President and CEO, David Thompson, will serve as the combined company’s CEO. Blake Larson, ATK Senior Vice President and President of the Aerospace Group, will serve as Chief Operating Officer for Orbital ATK. General Ronald Fogleman, USAF (Ret.), current Chairman of ATK’s Board of Directors, will serve as the Chairman of Orbital ATK’s Board of Directors. Garrett Pierce, Orbital’s Chief Financial Officer will serve as CFO of the combined company. The combined company will be headquartered in Dulles, Virginia.

Orbital was founded in 1982 and has approximately 3,600 employees. We expect the combined company to have approximately 13,000 employees. As we move through next steps and more information is publicly available, we will share it with you.

ATK’s Aerospace and Defense Groups are worldwide leaders, producers, suppliers and operators for our military, aerospace, and space-related customers. I am proud of our success and the respect and recognition we receive for our commitment to quality, schedule and mission success. Our implementation of PES has created streamlined processes, improved profit margins and affordability for our customers. I want to thank you for your personal commitment to execution excellence, our customers, to each other, and to our company.

I am excited about this proposed transaction. We have a longstanding relationship with Orbital that reflects similar cultures, complementary capabilities, and a common focus on innovation and affordability. Orbital has been ATK’s customer for over 25 years, and we have partnered on many successful programs. I am confident the transaction offers both parties the opportunity to create a strong, standalone A&D business with competitive programs, strong business execution and processes, and an innovative focus toward meeting emerging customer needs.

Next Steps

The spin-off of the Sporting Group enables the company to harness and invest resources to continue to broaden and deepen its leadership positions in outdoor recreation markets. The company will have a strong balance sheet and a competitive business model that will continue to support our growth strategy.

This transaction will allow the combined company to have the appropriate resources and focus to pursue A&D leadership in our markets with a strong and broad product offering. We see significant opportunities to positively perform and grow in our core U.S. Government and commercial businesses as new projects and investments ramp up, and as we continue to secure international contracts.

I am confident in the strength and future of our A&D business. Our Defense Group is an industry leader, securing contracts and delivering critical new capabilities to our military members and U.S. allies. Our Aerospace Group is the world's largest producer of solid rocket propulsion systems and a growing supplier of military and commercial aircraft structures, and small satellite capabilities. We believe the merger will enhance our strategic positioning in these businesses.

We anticipate closing these transactions by the end of calendar year 2014. The proposed spin-off and merger are subject to customary closing conditions, including approval of the transaction by ATK and Orbital shareholders and the receipt of required regulatory approvals.

I know that there are always questions and uncertainty in a season of change. I encourage you to read all of the materials we have provided, watch the employee video on ATKnet, and attend your team meetings. We will keep you apprised of developments as soon as we are able.

Both companies will continue to provide a competitive compensation and benefits package and offer career opportunities for employees in their specific business segments. We will carefully study the opportunities to combine the Orbital business with ATK A&D in a manner that builds on our collective past successes, and enables us to create a strong combined organization going forward.

Finally, and perhaps most importantly, we must continue our focus on safety and delivering superior quality and performance, because our customers count on our products every day. At this point, for the majority of our company, it is business as usual.

In all that we do, our ultimate success resides with you. Thank you for your continued hard work and dedication.

Sincerely,

Mark DeYoung

ATK President and Chief Executive Officer
