Exhibit 99.1

Our Company

We are a consumer packaged goods holding company, operating in the center-of-the-store, foodservice, ingredient, refrigerated, active nutrition and private label food categories. In February 2012, we completed our legal separation via a tax free spin-off from Ralcorp and began trading on the New York Stock Exchange under the ticker symbol “POST.”

Our Post Consumer Brands business includes the legacy Post Foods branded ready-to-eat (“RTE”) cereal operations, the business of MOM Brands, which we acquired in May 2015, and Attune Foods, which produces premium natural and organic granola, cereals and snacks. Our Michael Foods Group business is comprised of MFI Holding Corporation (which we refer to as Michael Foods), which we acquired in June 2014 and produces value-added egg products, refrigerated potato products and cheese and other dairy case products, as well as the businesses of National Pasteurized Eggs, Inc. (which we refer to as NPE), which we acquired in October 2016, Willamette Egg Farms, LLC (which we refer to as WEF), which we acquired in October 2015, and Dakota Growers Pasta Company, Inc. (which we refer to as Dakota Growers), which we acquired in January 2014 and manufactures and distributes pasta. Our Active Nutrition business includes the businesses of Premier Nutrition Corporation, which we acquired in September 2013, Dymatize Enterprises, LLC (which we refer to as Dymatize), which we acquired in February 2014, as well as the PowerBar brand, which we acquired in October 2014. Our Private Brands business includes the businesses of Golden Boy Foods Ltd. (which we refer to as Golden Boy), which we acquired in February 2014 and produces private label peanut and other nut butters, as well as dried fruits and snacking nuts, and American Blanching Company, which we acquired in November 2014 and manufactures peanut butter for national brands, private label retail and industrial markets and provides peanut blanching, granulation and roasting services for the commercial peanut industry. On July 3, 2017, we completed our acquisition of Weetabix, a United Kingdom-based packaged food company that produces and distributes branded and private label RTE, hot cereals and other cereal-based food products, breakfast drinks and muesli. For the fiscal year ended September 30, 2016, we generated net sales of $5,026.8 million, operating profit of $545.7 million, net loss of $3.3 million and Adjusted EBITDA of $933.9 million, and for the nine months ended June 30, 2017, we generated net sales of $3,777.3 million, operating profit of $404.2 million, net earnings of $34.1 million and Adjusted EBITDA of $702.7 million.

Since 2012, we have expanded and established new platforms through acquisitions, transforming us from a single category business to a more diversified, multi-category business with dynamic growth prospects. We operate a decentralized, adaptive business model, which provides us with more strategic flexibility. Our acquisition strategy focuses on businesses with product offerings that can strengthen our current portfolio, enable us to expand into complementary categories, geographic regions or distribution channels or provide diversification of cash flows in similar channels. We aim to improve scale in our operations, thereby increasing marketing and distribution efficiencies, and enhance our presence with key retailers. We believe the consumer foods market will continue to provide opportunities for growth through acquisitions of complementary businesses, and we are currently considering several acquisition opportunities. To the extent we do proceed with any acquisitions in the near term, we may finance the purchase price with cash on hand, proceeds from additional secured and/or unsecured borrowings of indebtedness, and possibly additional equity issuances. There can be no assurance, however, that we will continue to consider or pursue, or be successful in acquiring, any such businesses. While our activities to date have primarily focused on acquisitions, we completed the divestiture of certain assets including the PowerBar Australia assets and Musashi trademark in July 2015 and the sale of Michael Foods Canadian egg business in March 2016, and we expect that future activities also could include additional divestitures of businesses or portfolio companies, under appropriate circumstances, to further our business strategies.

Weetabix

On July 3, 2017, we completed the acquisition of Weetabix. Weetabix is a UK-based packaged food company that primarily produces RTE cereal products spanning branded and private label. Founded in 1932, Weetabix holds the number two overall position in the UK RTE cereal category. Its portfolio includes the Weetabix brand, which holds the number one brand position in the UK RTE cereal category, as well as Alpen (the number one muesli brand in the UK), Weetos, Ready Brek and Weetabix On The Go. In North America, Weetabix operates a natural and organic RTE cereal and snacking platform in both branded and private label, led by the Barbara’s brand and the Puffins sub-brand and serving natural and specialty channel and conventional retailers. Additionally, Weetabix has operations in Africa through two joint ventures and a distribution export business to over 90 countries.

The purchase price we paid in connection with the acquisition was approximately £1.4 billion, net of cash acquired. We funded the purchase price with cash on hand and proceeds of a $1.0 billion term loan under a joinder agreement under our existing credit agreement.

For the twelve-month period ended April 1, 2017, Weetabix had revenue of £406.4, earnings before income tax of £25.8 and Adjusted EBITDA of £127.5. The financial information for Weetabix presented above was prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. Such information has been prepared by our management from the unaudited books and records of Weetabix, and has not been audited or reviewed by any accounting firm. Accordingly, investors should not place undue reliance on such information. In addition, please note that audited annual financial statements of Weetabix, and related unaudited pro forma financial statements (which will present our combined and adjusted statements of operations and balance sheet data giving effect to the acquisition of Weetabix) are required to be filed with the SEC on Form 8-K, which filing will not be made until after the completion of this offering.

The following table provides a reconciliation of Adjusted EBITDA to earnings before income tax of Weetabix for the twelve-month period ended April 1, 2017. The financial information in such table has been derived from the books and records of Weetabix, which are prepared in accordance with IFRS. However, Adjusted EBITDA for Weetabix is a non-IFRS measure. The discussion in the notes to the “Summary Historical Financial Information” of non-GAAP financial measures also applies to the non-IFRS measure presented for Weetabix herein.

Summary Historical Financial Information

The following tables set forth certain summary historical condensed consolidated financial data for Post for each of the fiscal years in the three-year period ended September 30, 2016 and for the nine months ended June 30, 2017 and 2016. The summary historical financial data set forth below should be read in conjunction with: (i) the sections entitled “Use of Proceeds” and “Capitalization,” each of which are contained elsewhere in this offering memorandum, (ii) our audited consolidated financial statements and the notes thereto, and our “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for the fiscal year ended September 30, 2016 contained in our Annual Report on Form 10-K filed with the SEC on November 18, 2016 and incorporated by reference in this offering memorandum, and (iii) our unaudited condensed consolidated financial statements and the notes thereto and our “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” contained in our Quarterly Reports on Form 10-Q for the fiscal quarters ended December 31, 2016, March 31, 2017 and June 30, 2017, each filed with the SEC and incorporated by reference in this offering memorandum.

The summary historical condensed consolidated financial data for each of the fiscal years in the three-year period ended September 30, 2016 have been derived from Post’s audited consolidated financial statements. The summary unaudited historical condensed consolidated financial data for Post for the nine months ended June 30, 2017 and 2016 have been derived from Post’s unaudited condensed consolidated financial statements, and include, in the opinion of management, all adjustments, consisting of normal, recurring adjustments, necessary for a fair presentation of such information. The financial data presented for the interim periods are not necessarily indicative of the results for the full fiscal year.

The summary unaudited historical consolidated financial data for the twelve months ended June 30, 2017 were calculated by subtracting the summary historical consolidated financial information for Post for the nine months ended June 30, 2016 from the summary historical consolidated financial information for Post for the fiscal year ended September 30, 2016, and then adding the summary historical consolidated financial information for Post for the nine months ended June 30, 2017.

The indentures governing our senior notes use EBITDA (with additional adjustments similar to those discussed in note (5) below regarding our calculation of “Adjusted EBITDA”) to measure our compliance with covenants such as

interest coverage and leverage. Our management also believes EBITDA is an acceptable indicator of our ability to incur and service debt and make capital expenditures. We believe that EBITDA is a useful financial metric to assess our operating performance from period to period by excluding certain items that we believe are not representative of our core business.

EBITDA has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

Because of these limitations, EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business. We compensate for these limitations by relying primarily on our GAAP results and using EBITDA only supplementally.
