KRAFT FOODS GROUP PROVIDES FINANCIAL UPDATE AND

ANNOUNCES CHANGE IN POST-EMPLOYMENT BENEFIT STRATEGY

NORTHFIELD, Ill. – Feb. 15, 2013 – Kraft Foods Group, Inc. (NASDAQ: KRFT) today updated its financial outlook for fourth quarter 2012 and full year 2013. Fourth quarter results will reflect the impact of greater-than-anticipated trade inventory reductions, offset by strong gains from cost-savings measures. The company also announced a new, comprehensive strategy for post-employment benefits designed to improve transparency, simplify accounting, and reduce funding volatility.

“We continue to make important changes to re-make Kraft into an industry leader that delivers steady, growing shareholder returns,” said Tony Vernon, CEO of Kraft. “While we weren’t satisfied with our revenue in the fourth quarter, our innovation, productivity and overhead cost reduction programs are paying off. This enabled a double-digit increase in advertising, solid profit from operations and sizable cash flow. We’re off to a strong start so far this year and we remain well-positioned to drive profitable growth in 2013 and beyond.”

Q4 2012 RESULTS UPDATE

Fourth quarter 2012 net revenue is expected to be 10.7 percent lower than the prior year; lapping 9.2 percent growth in fourth quarter 2011. The decline includes a negative impact of 4.2 percentage points due to a 53^rd week of sales in the prior year as well as a 0.7 percentage point positive net impact from currency and sales to Mondelēz International, Inc.

Organic Net Revenue² is expected to have declined 7.2 percent versus the prior year quarter, lapping 7.8 percent Organic Net Revenue growth in fourth quarter 2011. The decline was due to a negative 6.8 percentage point impact from reductions in trade inventories, as well as a 1.2 percentage point impact from product pruning.

Fourth quarter operating income is expected to be approximately $260 million including a negative impact of approximately $225 million of market-based impacts from post-employment benefits³ as well as approximately $135 million of Restructuring Program⁴ charges and $46 million of unrealized losses from hedging activities.

Excluding these factors, the company expects to report solid gains from operations versus the prior year quarter. The gains from operations will reflect a reduction in ongoing post-employment benefit costs together with strong gains from productivity and overhead cost reductions that more than offset the impact of lower sales volumes due to retail trade destocking, incremental costs of being an independent public company and a double-digit increase in advertising investment.

The company expects to report earnings of approximately $0.15 per diluted share in fourth quarter 2012 including a one-time, non-cash charge of approximately $0.24 per share due to the market-based impact from post-employment benefits, approximately $0.14 per share of Restructuring Program charges and $0.04 per share of unrealized losses from hedging activities.

The company expects to report final 2012 results, including gross profit, SG&A and segment operating income details, as well as updated historical financial results reflecting the post-employment benefit changes for 2011 and 2010 no later than March 29, 2013.

OUTLOOK FOR 2013

Kraft also updated its guidance for 2013. Consistent with previous guidance, Organic Net Revenue growth is expected to be in line with the growth of the North American food and beverage market despite a negative impact of approximately one percentage point from product pruning.

Earnings per share are expected to be approximately $2.75, up from the previous guidance of approximately $2.60. The adjustment to guidance reflects:

Total Restructuring Program costs in 2013 are now expected to be approximately $300 million, or $0.33 per share, up from approximately $240 million previously. Total expected costs over the life of the Restructuring Program remain approximately $650 million.

IMPLEMENTING NEW POST-EMPLOYMENT BENEFIT STRATEGY

The company is executing a four-part strategy to better manage and reduce the volatility of expenses and cash outlays related to its post-employment benefit obligations.

The company expects the 2013 contributions to be funded from cash on hand, as it delivered strong cash flow in 2012 and ended the year with approximately $1.3 billion in net cash and cash equivalents. It expects contributions thereafter to be funded through cash flow from operations. None of the actions outlined today is expected to adversely affect the company’s standing with regard to its debt covenants or its ability to grow its dividend.

“The changes we’re implementing will provide greater transparency to Kraft’s underlying operating results and increase the reliability of future cash generation for shareholders,” said Tim McLevish, EVP and CFO.

BASIS OF PRESENTATION

The condensed consolidated financial statements include Kraft Foods Group, as well as its wholly owned subsidiaries. All intercompany transactions are eliminated. Prior to the spin-off on Oct. 1, 2012, Kraft’s financial statements were prepared on a stand-alone basis and were derived from the consolidated financial statements and accounting records of Kraft’s former parent company, Mondelēz International. Kraft’s financial statements included certain expenses of Mondelēz International which were allocated to Kraft for certain functions, including general corporate expenses related to finance, legal, information technology, human resources, compliance, shared services, insurance, employee benefits and incentives and stock-based compensation. Kraft considers the expense allocation methodology and results to be reasonable for all periods presented. However, these allocations were not necessarily indicative of the actual expenses it would have incurred as an independent public company or of the costs it will incur in the future.

Kraft manufactures and markets food and beverage products, including refrigerated meals, refreshment beverages and coffee, cheese and other grocery products, primarily in the United States and Canada. It manages and reports operating results through five reportable segments. Kraft’s reportable segments are Beverages (formerly known as the U.S. Beverages segment), Cheese (formerly known as the U.S. Cheese segment), Refrigerated Meals (formerly known as the U.S. Convenient Meals segment), Grocery (formerly known as the U.S. Grocery segment) and International & Foodservice (formerly known as the Canada & N.A. Foodservice segment). Kraft includes its Puerto Rico and export operations within its International & Foodservice segment.

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, 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 a business from a foreign country), currency and the 53rd week of shipments in 2011. Kraft uses Organic Net Revenues and corresponding metrics as non-GAAP financial measures. Management believes Organic Net Revenues better reflect the underlying growth from the ongoing activities of Kraft’s business and provide 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 and twelve months ended Dec. 29, 2012 and Dec. 31, 2011. 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.
