Item 8.01 Other Events.

State Street Bank and Trust Company, as trustee (“the Trustee”) of the Alion Science and Technology Corporation (“Alion” or the “Company”) Employee Ownership, Savings and Investment Plan (the “ESOP”), has selected a final value of $2.45 per share for Alion’s common stock on August 20, 2014 (the “Valuation Date”). This value is effective for the period ending March 31, 2014 and considers, among other factors, the company’s financial performance through March 31, 2014 as well as the terms of the refinancing as disclosed just prior to closing on August 18, 2014.

The Trustee engaged an outside independent third party valuation firm to assist the Trustee in establishing a value for the Company’s common stock as of the Valuation Date using the following valuation methods:

Valuations conducted by the valuation firm on behalf of the Trustee prior to September 30, 2011 used the Discounted Cash Flow Method, the Transaction Method and the Guideline Company Method. The valuation firm has not used the Guideline Company Method since the March 31, 2011 valuation analysis. Though pricing multiples have improved for the guideline companies (within Alion’s industry) between September 30, 2013 and the Valuation Date, they remain below historical norms and are still below pricing multiples implied by recent merger and acquisition activity in the U.S. federal government contracting sector. The gap between the pricing multiples of the guideline companies and recent transactions in the industry suggests that current pricing multiples for non-controlling ownership interests may not be as meaningful for purposes of valuing a controlling ownership interest.

In addition to factors related to this valuation period, the valuation firm considered the effects of Alion’s refinancing, based on the refinancing terms which were expected as of the time the valuation was prepared.

Some of the notable factors that changed for this valuation period from the September 30, 2013 valuation include the following:

The valuation firm prepared a written report, which is solely for the Trustee’s use in connection with its administration and operation of the ESOP, containing its procedures, analyses, and opinion as to the appropriate value of the Company’s common stock. In preparing its report, the valuation firm used various financial and other information provided to the valuation firm by Alion’s management or obtained from other private and public sources including financial projections prepared by management of the Company, and relied on the accuracy and completeness of this information. There is no assurance that the valuation firm, or any other financial adviser that the Trustee might choose, will utilize the same process of methodologies in connection with future valuations of Alion common stock, or that such advisor(s) will reach conclusions that are consistent with those reached in the valuation firm’s report.
