Greif president and CEO Ole Rosgaard said: “Our team delivered an outstanding third-quarter financial result, remaining steadfast and execution-focused during a time of macroeconomic uncertainty.
“This commitment has led to a rock-solid balance sheet, record free cash flow generation, and EBITDA growth.
“Our team has done an outstanding job transforming our business, as evidenced by volume growth compared to pre-pandemic 2019 volume levels, despite sequential declines from higher volumes last year.
“In addition to financial success, our teams have continued to deliver Legendary Customer Service, and made notable progress to further foster Thriving Communities at Greif and Protect Our Future through industry-leading sustainability practice.”
In January this year, Greif agreed to sell a 50% stake in its Flexible Packaging joint venture to plastic film manufacturer Gulf Refined Packaging.
