Earnings Conference Call and Webcast

As previously disclosed, effective April 1, 2017, CSC became a wholly owned subsidiary of DXC Technology Company, an independent public company formed in connection with the spin-off and combination with CSC of the Enterprise Services business of the Hewlett Packard Enterprise Company (“HPES”). CSC common stock was suspended from trading on the NYSE effective as of the opening of trading on April 3, 2017. CSC filed a Form 15 with the SEC on April 18, 2017 to deregister the shares of CSC common stock. DXC common stock began regular-way trading under the symbol “DXC” on the New York Stock Exchange on April 3, 2017.

This press release is the earnings release of CSC, and the financial information set forth herein relates only to CSC and its subsidiaries, as of and for the two years ended March 31, 2017 and as of and for the three-month periods ended March 31, 2017 and April 1, 2016, which predate the April 1, 2017 effective date of the previously disclosed merger transaction involving CSC. This press release does not include the financial results of HPES for any periods. Accordingly, unless the context otherwise requires, references herein to “CSC,” the “Company,” “we,” “us” or “our” refer only to CSC and its pre-combination subsidiaries and not to DXC, HPES or their pre-combination subsidiaries.

Beginning with the first quarter press release for the quarter ending June 30, 2017, DXC will report on a consolidated basis representing the combined operations of CSC and HPES and their respective subsidiaries. Because CSC is deemed the acquirer in this combination for accounting purposes under U.S. Generally Accepted Accounting Principles (GAAP), CSC is considered DXC’s predecessor, and the historical financial statements of CSC prior to April 1, 2017 will be reflected in DXC’s future quarterly and annual reports as DXC’s historical financial statements.

Non-GAAP Financial Measures

We present non-GAAP financial measures of performance which are derived from the consolidated financial information of CSC. These non-GAAP financial measures include constant currency, consolidated segment operating income and margin, consolidated segment adjusted operating income and margin, consolidated segment commercial operating income and margin, earnings before interest and taxes (EBIT) and margin, adjusted EBIT and margin, non-GAAP income from continuing operations before taxes, non-GAAP net income from continuing operations, non-GAAP EPS from continuing operations and adjusted free cash flow.

We present these non-GAAP financial measures to provide investors with meaningful supplemental financial information, in addition to the financial information presented on a U.S. GAAP basis. Non-GAAP financial measures exclude certain items otherwise required by U.S. GAAP which management believes are not indicative of core operating performance. We believe these non-GAAP measures allow investors to better understand the financial performance of CSC exclusive of the impacts of corporate wide strategic decisions. We believe that adjusting for these items provides investors with additional measures to evaluate the financial performance of our core business operations on a comparable basis from period to period. We believe the non-GAAP measures provided are also considered important measures by financial analysts covering CSC as equity research analysts publish estimates and research notes based on our non-GAAP commentary, including our guidance around non-GAAP EPS.

There are limitations to the use of the non-GAAP financial measures we present. One of the limitations is that they do not reflect complete financial results. We compensate for this limitation by providing a reconciliation between our non-GAAP financial measures and the respective most directly comparable financial measure calculated and presented in accordance with GAAP. Additionally, other companies, including companies in CSC’s industry, may calculate non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes between companies. Consolidated segment operating income and consolidated segment adjusted operating income are useful measures in evaluating the financial performance of CSC’s core segment business operations on a more comparable basis year-over-year. However, these measures could limit one’s ability to assess CSC’s financial performance by excluding corporate G&A and certain other items. To compensate for this limitation, we provide a reconciliation between these measure and income from continuing operations, before taxes, which is the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP.

Reconciliation of Non-GAAP Financial Measures

CSC’s non-GAAP adjustments include:

Consolidated Segment Operating Income and Consolidated Segment Adjusted Operating Income

We define consolidated segment operating income as revenues less costs of services, associated depreciation and amortization expense, restructuring costs, and segment SG&A expenses. Consolidated segment operating income excludes pension and OPEB actuarial and settlement losses and corporate G&A, which is largely associated with centrally managed overhead and shared-services functions which are not controlled by segment level leadership nor directly related to CSC’s core segment business operations. Consolidated segment adjusted operating income further excludes the impacts of corporate wide strategic decisions, such as segment related restructuring and other transaction costs. We define consolidated segment operating margin and consolidated segment adjusted operating margin as consolidated segment operating income and consolidated segment adjusted operating income as a percentage of revenues. A reconciliation of consolidated segment operating income and consolidated segment adjusted operating income to income from continuing operations, before taxes is as follows:

EBIT and Adjusted EBIT

A reconciliation of adjusted EBIT and EBIT to net income (loss) is as follows:

Adjusted Free Cash Flow

A reconciliation of net cash provided by operating activities to adjusted free cash flow is as follows:

Consolidated Segment Adjusted Operating Income and Margins

A reconciliation of consolidated segment operating income to consolidated segment adjusted operating income is as follows:

Non-GAAP Results

A reconciliation of non-GAAP results to the respective most directly comparable financial measure calculated and presented in accordance with GAAP is as follows:
