Acquisition Agreement

On May 27, 2015, CA, Inc., a Delaware corporation (the “Company”), Rally Software Development Corp., a Delaware corporation (“Rally”), and Grand Prix Acquisition Corp., a Delaware corporation and wholly owned subsidiary of the Company (“Purchaser”), entered into an Acquisition Agreement (the “Acquisition Agreement”). Pursuant to the Acquisition Agreement, and upon the terms and subject to the conditions thereof, Purchaser has agreed to commence a cash tender offer to acquire all of the shares of Rally’s common stock (the “Offer”) for a purchase price of $19.50 per share, net to the holders thereof in cash, without interest (the “Offer Price”). On May 27, 2015, the boards of directors of both the Company and Rally approved the terms of the Acquisition Agreement.

The consummation of the Offer will be conditioned on (i) at least a majority of the shares of Rally’s common stock having been validly tendered into and not withdrawn from the Offer, (ii) receipt by the Company and Purchaser of certain regulatory approvals, (iii) the accuracy of the representations and warranties contained in the Acquisition Agreement, subject to certain qualifications, and (iv) other customary conditions. The Offer is not subject to a financing condition.

Following the consummation of the Offer, the Acquisition Agreement provides that Purchaser will merge with and into Rally (the “Merger”) and Rally will become a wholly owned subsidiary of the Company. In the Merger, each outstanding share of Rally’s common stock (other than shares owned by the Company, Rally or Purchaser or any of their direct or indirect wholly owned subsidiaries and shares with respect to which appraisal rights are properly exercised in accordance with Delaware law) will be converted into the right to receive the Offer Price. The consummation of the Merger is subject to certain closing conditions.

In addition, in connection with the transactions contemplated by the Acquisition Agreement, all vested options and vested restricted stock units of Rally will be converted into the right to receive cash based on a formula described in the Acquisition Agreement, and all unvested options and unvested restricted stock units will be converted into the right to receive cash that will vest on the same terms and conditions set forth in the applicable stock plans of Rally under which they were granted and the applicable agreements evidencing the grants thereof, including without limitation provisions with respect to vesting.

The Acquisition Agreement contains customary representations, warranties and covenants of the parties. Rally has agreed to refrain from engaging in certain activities until the effective time of the Merger. In addition, under the terms of the Acquisition Agreement, Rally agrees not to solicit or support any alternative acquisition proposals, subject to customary exceptions for Rally to respond to and support unsolicited proposals in the exercise of the fiduciary duties of the board of directors of Rally. Rally will be obligated to pay a termination fee of $17.4 million to the Company in certain circumstances.

The foregoing description of the Acquisition Agreement does not purport to be complete and is qualified in its entirety by reference to the Acquisition Agreement, which is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference. The Acquisition Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Rally or Purchaser. In particular, the assertions embodied in the representations and warranties contained in the Acquisition Agreement are made solely for the benefit of the parties thereto and the representations and warranties of Rally set forth therein are qualified by information in confidential disclosure schedules provided by Rally in connection with the signing of the Acquisition Agreement. These confidential disclosure schedules contain information that modify, qualify and create exceptions to the representations and warranties of Rally set forth in the Acquisition Agreement. Moreover, certain representations and warranties in the Acquisition Agreement were used for the purpose of allocating risk between the Company, Rally and Purchaser, rather than establishing matters of fact. Accordingly, the representations and warranties in the Acquisition Agreement may not constitute the actual state of facts about the Company, Rally or Purchaser.

Support Agreements

In order to induce the Company and Purchaser to enter into the Acquisition Agreement, certain of Rally’s directors and named executive officers, solely in his or her capacity as a stockholder of Rally, entered into Support Agreements with the Company and Purchaser (the “Support Agreements”), concurrent with the execution and delivery of the Acquisition Agreement. Shares held by these directors and officers and their affiliates subject to the Support Agreements represent, in the aggregate, approximately 5.9% of the shares of Rally’s common stock outstanding on the date of the Acquisition Agreement (including shares issuable upon exercise of options and other convertible securities). Subject to the terms and conditions of the Support Agreements, such stockholders agreed, among other things, solely in their capacities as stockholders of Rally, to tender their shares in the Offer and, if required, to vote their shares in favor of adoption of the Acquisition Agreement.

Updated Guidance

While the Company will provide official guidance upon consummation of the Merger described above, the estimated financial impact of the Merger is provided by the Company herein. The following information contains “forward-looking statements” (as defined below). As compared with the Company’s previous fiscal year 2016 guidance, the Company expects the Merger to: add between one to two percentage points of revenue; be modestly dilutive to both operating margins and diluted earnings per share; adversely affect GAAP operating margin by two percentage points and non-GAAP operating margin by one percentage point (with the 1% difference between the effect on GAAP and non-GAAP operating margin primarily related to purchased software amortization); and have no material effect on our cash flow from operations.

Please see below for information regarding non-GAAP financial measures, the cautionary statement regarding forward-looking statements, and the reconciliation of projected GAAP metrics to projected non-GAAP metrics, which are part of the disclosure under this Item 7.01 of Form 8-K.

Non-GAAP Financial Measures

This Form 8-K and the accompanying table include certain financial measures that exclude the impact of certain items and therefore have not been calculated in accordance with U.S. generally accepted accounting principles (GAAP). Non-GAAP metrics for operating margin exclude the following items: share-based compensation expense; non-cash amortization of purchased software and other intangible assets; charges relating to rebalancing initiatives that are large enough to require approval from the Company’s Board of Directors, fiscal 2007 restructuring costs and certain other gains and losses, which include the gains and losses since inception of hedges that mature within the quarter, but exclude gains and losses of hedges that do not mature within the quarter. The Company began expensing costs for internally developed software where development efforts commenced in the first quarter of fiscal 2014. Due to this change, the Company also adds back capitalized internal software costs and excludes amortization of internally developed software costs previously capitalized from these non-GAAP metrics. These non-GAAP financial measures may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. By excluding these items, non-GAAP financial measures facilitate management’s internal comparisons to the Company’s historical operating results to competitors’ operating results and to estimates made by securities analysts. Management uses these non-GAAP financial measures internally to evaluate its performance and they are key variables in determining management incentive compensation. The Company believes these non-GAAP financial measures are useful to investors in allowing for greater transparency of supplemental information used by management in its financial and operational decision-making.

Cautionary Statement Regarding Forward-Looking Statements

Certain statements in this communication (such as statements containing the words “believes,” “plans,” “anticipates,” “expects,” “estimates,” “targets” and similar expressions relating to the future) constitute “forward-looking statements” that are based upon the beliefs of, and assumptions made by, the Company’s management, as well as information currently available to management. These forward-looking statements reflect the Company’s current views with respect to future events and are subject to certain risks, uncertainties, and assumptions. A number of important factors could cause actual results or events to differ materially from those indicated by such forward-looking statements, including: the ability to consummate the transaction; the risk that an insufficient number of Rally’s stockholders tender into the Offer; the risk that regulatory approvals required for the acquisition are not obtained or are obtained subject to conditions that are not anticipated; the risk that the other conditions to the closing of the acquisition are not satisfied; potential adverse reactions or changes to customer, supplier, partner or employee relationships, including those resulting from the announcement or completion of the acquisition; uncertainties as to the timing of the acquisition; competitive responses to the proposed acquisition; response by activist stockholders to the acquisition; uncertainty of the expected financial performance of the Company following completion of the proposed transaction; the ability to successfully integrate Rally’s operations and employees in a timely manner; the ability to realize anticipated synergies, cost savings and operational efficiencies; unexpected costs, charges or expenses resulting from the acquisition; litigation relating to the acquisition; the inability to retain key personnel; any changes in general economic and/or industry specific conditions; and other factors described more fully in the Company’s filings with the U.S. Securities and Exchange Commission (the “SEC”). Should one or more of these risks or uncertainties occur, or should the Company’s assumptions prove incorrect, actual results may vary materially from those described herein as believed, planned, anticipated, expected, estimated, targeted or similarly expressed in a forward-looking manner. The Company assumes no obligation to update the information in this communication, except as otherwise required by law. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
