Exhibit 99.1

TreeHouse Foods, Inc. Reports First Quarter 2018 Results Towards the Upper End of Its Guidance Range;

Company Reaffirms Full Year Guidance

HIGHLIGHTS

Oak Brook, IL, May 3, 2018 — TreeHouse Foods, Inc. (NYSE: THS) today reported first quarter GAAP loss per fully diluted share of $(0.60) compared to GAAP income of $0.49 reported for the first quarter of 2017. The Company reported adjusted earnings per fully diluted share

“In the first quarter, we delivered both revenue and adjusted earnings per share above the midpoint of our guidance range,” said Steve Oakland, Chief Executive Officer and President. “Our progress to date has been solid, and I continue to be impressed with the tremendous effort our team is putting towards the key elements of TreeHouse 2020.”

“Our work to address near term challenges such as margin recovery is ongoing. More broadly, we are working to better position ourselves to address the evolving retail landscape,” continued Mr. Oakland. “As a private label industry leader, we are in the ideal position within food and beverage as private label continues to grow at the expense of brands. This year continues to be one of transition, but I’m encouraged by the progress we are making around TreeHouse 2020, our Structure to Win SG&A initiative, supply chain optimization, and rolling out our TreeHouse Management Operating Structure,” Mr. Oakland said.

Matthew Foulston, Chief Financial Officer of TreeHouse, continued, “I’m pleased with our start to the year. First quarter sales increased 1.9%, excluding the (2.8)% impact of the SIF divestiture last year and an approximate (2.7)% drag due to our SKU rationalization efforts. The year-over-year segment direct operating income decline was largely expected and was driven by pricing that has yet to fully cover higher commodity and escalating freight costs; offset, in part, by tighter SG&A expense control.”
