All written or oral statements made by CSC at this meeting or in these presentation materials
that do not directly and exclusively relate to historical facts constitute “forward-looking
statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These
statements represent CSC’s expectations and beliefs, and no assurance can be given that
the results described in such statements will be achieved. These statements are subject to
risks, uncertainties, and other factors, many outside of CSC’s control, that could cause actual
results to differ materially from the results described in such statements. For a description of
these factors, please see CSC’s most recent Annual Report on Form 10-K and Quarterly
Reports on Form 10-Q.

Fiscal Year 2011 information presented herein is based on CSC’s revised guidance issued on
May 2, 2011. Actual results for Fiscal Year 2011 are scheduled to be released on May 25,
2011. Actual Fiscal Year 2011 results could vary from such guidance information.

INVESTOR CONFERENCE 2011

This presentation includes certain non-GAAP financial measures, such as operating income,
operating margin, operating costs, free cash flow and free cash flow as a percentage of net income
attributable to CSC common shareholders. These non-GAAP financial measures are not meant to
be considered in isolation or as a substitute for results prepared in accordance with accounting
principles generally accepted in the United States (GAAP). A reconciliation of non-GAAP financial
measures included in this presentation to the most directly comparable financial measure calculated
and presented in accordance with GAAP is set forth elsewhere in this presentation and on our
website at www.csc.com. CSC management believes that these non-GAAP financial measures
provide useful information to investors regarding the Company’s financial condition and results of
operations as they provide another measure of the Company’s profitability and ability to service its
debt, and are considered important measures by financial analysts covering CSC and its peers.
