Examples of forward-looking statements include, but are not limited to, statements regarding Kraft’s growth, progress, Organic Net Revenue growth, EPS and Free Cash Flow. These forward-looking statements are not guarantees of future performance and are subject to a number of risks and uncertainties, many of which are beyond Kraft’s control. Important factors that could cause actual results to differ materially from those indicated in the forward-looking statements include, but are not limited to, increased competition; continued consumer weakness and weakness in economic conditions; Kraft’s ability to differentiate its products from retailer and economy brands; Kraft’s ability to maintain its reputation and brand image; continued volatility and increases in commodity and other input costs; pricing actions; increased costs of sales; regulatory or legal changes, restrictions or actions; unanticipated expenses and business disruptions; product recalls and product liability claims; unexpected safety or manufacturing issues; Kraft’s indebtedness and its ability to pay its indebtedness; Kraft’s inability to protect its intellectual property rights; tax law changes; Kraft’s ability to achieve the benefits it expects to achieve from the spin-off and to do so in a timely and cost-effective manner; and its lack of operating history as an independent, publicly traded company. For additional information on these and other factors that could affect Kraft’s forward-looking statements, see Kraft’s risk factors, as they may be amended from time to time, set forth in its filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December 29, 2012.

NON-GAAP FINANCIAL MEASURES

Kraft reports its financial results in accordance with accounting principles generally accepted in the United States (“GAAP”).

Kraft’s top-line measure is Organic Net Revenues, which is defined as net revenues excluding the impact of transactions with Mondelēz International, Inc., acquisitions, divestitures (including the termination of a full line of business due to the loss of a licensing or distribution arrangement, and the complete exit of business out of a foreign country), currency and the 53rd week of shipments in 2011. Organic Net Revenues is a non-GAAP financial measure that management believes better reflects the underlying growth from the ongoing activities of Kraft’s business and provides improved comparability of results.

See the attached schedules for supplemental financial data and corresponding reconciliations of the non-GAAP financial measures referred to above to the most comparable GAAP financial measures for the three months ended March 30, 2013 and March 31, 2012. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, Kraft’s results prepared in accordance with GAAP. In addition, the non-GAAP measures Kraft uses may differ from non-GAAP measures used by other companies, and other companies may not define the non-GAAP measures Kraft uses in the same way.
