Item 2.02. Results of Operations and Financial Condition

On May 4, 2017, TreeHouse Foods, Inc. (NYSE: THS) issued a press release announcing its financial and operating results for the fiscal quarter ended March 31, 2017 and providing information relating to its previously announced webcast being held to discuss such results. A copy of this press release is furnished as Exhibit 99.1 to this report and is incorporated herein by reference.

Item 8.01. Other Events

In the first quarter of 2017, TreeHouse Foods, Inc. completed changes in its organizational structure that resulted in a change in how the Company manages its business and allocates resources. The Company’s reportable segments are now organized and managed by products: Baked Goods, Beverages, Condiments, Meals, and Snacks. Previously, TreeHouse’s reportable segments were organized and managed by customer channels: North American Retail Grocery, Food Away From Home, and Industrial and Export. All prior period information has been recast to reflect this change.

The Company manages operations on a company-wide basis, thereby making determinations as to the allocation of resources in total rather than on a segment-level basis. The Company has designated reportable segments based on how management views its business. The reportable segments, as presented below, are consistent with the manner in which the Company reports its results to the Chief Operating Decision Maker.

The Company evaluates the performance of its segments based on net sales dollars and direct operating income. In conjunction with the change in segments, the Company revised its calculation of direct operating income to include direct general and administrative expenses. Direct operating income is now defined as gross profit less freight out, sales commissions, and direct selling, general, and administrative expenses.

For comparability and investor analysis purposes, the Company is recasting the presentation of selected segment information by quarter for 2016 and 2015. These changes do not affect the Company’s Consolidated Statements of Income, Consolidated Balance Sheets, Consolidated Statements of Stockholders’ Equity, or Consolidated Statements of Cash Flows.

The selected segment information is furnished as Exhibit 99.2 to this report and is incorporated herein by reference.

The information in this Form 8-K under Item 2.02, Item 8.01, Exhibit 99.1, and Exhibit 99.2 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific referencing in such filing.
