Exhibit 99.1

Post Holdings Announces Formation of 8th Avenue Food & Provisions

• Post and THL to capitalize newly created business, 8th Avenue Food & Provisions

• 8th Avenue creates opportunity to drive consolidation in private brands

• Post to retain 60.5% of common equity; $875 million cash proceeds fully monetizes Post’s net asset investment and results in deleveraging to 5.5x

St. Louis - August 2, 2018 - Post Holdings, Inc. (NYSE:POST) (“Post”), a consumer packaged goods holding company, announced today it has formed 8th Avenue Food & Provisions (“8th Avenue”), consisting of Post’s private brands business, and it has entered into an agreement with Thomas H. Lee Partners, Inc. (“THL”), a premier private equity firm investing in middle market growth companies since 1974, pursuant to which Post and THL together will separately capitalize 8th Avenue.

Post explored a range of structural alternatives for its private brands business resulting in Post and THL agreeing to organize and capitalize 8th Avenue for the purpose of driving consolidation in the private brands category. Jim Dwyer will continue as President and Chief Executive Officer of 8th Avenue. 8th Avenue management, Post management and THL have deep expertise operating and executing transactions in the private brands and consumer packaged goods categories, and together will develop opportunities for 8th Avenue. By retaining a meaningful ownership of 8th Avenue, Post will participate in 8th Avenue’s growth while preserving the option to pursue a tax-efficient separation of its remaining position in 8th Avenue.

“We are excited about the potential to grow 8th Avenue Food & Provisions,” said Rob Vitale, President and Chief Executive officer of Post Holdings. “We could not ask for a better partner than THL and we are delighted to continue working with Jim Dwyer in further developing the business.”

The transaction is expected to be completed in October, subject to certain closing conditions, including the expiration of waiting periods under U.S. antitrust laws. Post will appoint five of the members of 8th Avenue’s Board of Directors, and THL will appoint one member.

Financial Details

Under the terms of the transaction, Post is expected to receive total proceeds of $875 million, fully monetizing the net investment Post has made in its private brands business. Final proceeds are anticipated to be funded by $250 million from THL and 8th Avenue’s assumption of $625 million of debt. Post will retain 60.5% of the common equity in 8th Avenue. THL will receive 8th Avenue preferred stock with an 11% PIK-equivalent, cumulative, quarterly compounding dividend and 39.5% of the common equity in 8th Avenue. 8th Avenue and its subsidiaries will become unrestricted subsidiaries of Post, and 8th Avenue debt will be non-recourse to Post. Post will use its net proceeds to pay down a portion of its existing approximately $2.2 billion term loan, reducing its pro forma net leverage ratio to 5.5x. Post will continue to provide certain services to 8th Avenue under a master services agreement.

For the last twelve months ended June 30, 2018, 8th Avenue had net earnings of $77.1 million and Adjusted EBITDA of $103.1 million. Adjusted EBITDA was calculated on a pro forma basis to give effect to certain master services fees and advisory fees expected to be paid to Post and THL from 8th Avenue following the consummation of the transaction and excludes anticipated cost synergies resulting from the integration of the existing private brands businesses. Adjusted EBITDA is a non-GAAP measure. For additional information regarding non-GAAP measures, see the related explanations presented under “Use of Non-GAAP Measure” and “Explanation and Reconciliation of Non-GAAP Measure” later in this release.

Use of Non-GAAP Measure

Post uses Adjusted EBITDA, a non-GAAP measure, in this release to supplement its financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP). Adjusted EBITDA is not prepared in accordance with U.S. GAAP, as it excludes certain items as listed later in this release, and may not be comparable to similarly-titled measures of other companies.

Post management uses certain non-GAAP measures, including Adjusted EBITDA, as key metrics in the evaluation of underlying company and segment performance, in making financial, operating and planning decisions, and, in part, in the determination of cash bonuses for its executive officers and employees. Management believes the use of non-GAAP measures, including Adjusted EBITDA, provides increased transparency and assists investors in understanding the underlying operating performance of 8th Avenue and in the analysis of ongoing operating trends.

EXPLANATION AND RECONCILIATION OF NON-GAAP MEASURE

Post uses Adjusted EBITDA, a non-GAAP measure, in this presentation to supplement its financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP). Adjusted EBITDA is not prepared in accordance with U.S. GAAP, as it excludes certain items as listed below, and may not be comparable to similarly-titled measures of other companies.

Post believes that Adjusted EBITDA is useful to investors in evaluating 8th Avenue’s operating performance and liquidity because (i) Post believes it is widely used to measure a company’s operating performance without regard to items such as depreciation and amortization, which can vary depending upon accounting methods and the book value of assets, (ii) it presents a measure of corporate performance exclusive of a company’s capital structure and the method by which the assets were acquired, and (iii) it is a financial indicator of a company’s ability to service its debt. Management uses Adjusted EBITDA to provide forward-looking guidance and to forecast future results. Adjusted EBITDA reflects adjustments for income tax benefit, depreciation and amortization, as well as the following adjustment:

a. Integration costs: Post has excluded integration costs incurred to integrate acquired or to-be-acquired businesses as Post believes that these exclusions allow for more meaningful evaluation of 8th Avenue’s current operating performance and comparisons of 8th Avenue’s operating performance to other periods. Post believes such costs are generally not relevant to assessing or estimating the long-term performance of acquired assets as part of 8th Avenue, and such costs are not factored into management’s evaluation of potential acquisitions or its performance after completion of an acquisition. In addition, the frequency and amount of such charges varies significantly based on the size and timing of the acquisitions and the maturity of the businesses being acquired. Also, the size, complexity and/or volume of past acquisitions, which often drive the magnitude of such expenses, may not be indicative of the size, complexity and/or volume of future acquisitions. By excluding these expenses, management is better able to evaluate 8th Avenue’s ability to utilize its existing assets and estimate the long-term value that acquired assets will generate for 8th Avenue. Furthermore, Post believes that the adjustments of these items more closely correlate with the sustainability of 8th Avenue’s operating performance.
