He began building the packaging empire in 2006 in the protracted $3.3b Carter Holt Harvey takeover. He went on to buy International Paper's beverage packing unit for US$500m and Swiss company SIG for €1.69b ($2.9b) the following year. Alcoa's packaging business was added in 2008 for US$2.7b.
Hart then ramped up the expansion in 2010, spending US$6.5b on the leveraged buyout of Pactiv and then US$4.5b buying Graham Packaging and US$395m on Canada's Dopaco in 2011.
The deals were largely funded through debt, with Hart taking advantage of the slump in global interest rates by selling junk bonds to create the world's second-biggest food and drink packaging investor behind Sweden's Tetra Laval. Annual revenue peaked at US$13.97b in 2013, a year when Reynolds Group's total borrowings were at US$17.94b. That's been whittled down to US$11b.
Reynolds Group sold SIG in 2015 for €3.6b and in 2017 it sold the Closure and Graham businesses in Asia for US$99m.
Last month, Reynolds Group said its second-largest division - consumer products - had confidentially submitted a draft initial public offering registration to the US SEC. Consumer products generated adjusted earnings of US$294m in the six months through June on revenue of US$1.46b.
"The number of shares to be offered and the price range for the proposed offering have not yet been determined. The initial public offering is expected to commence after the SEC completes its review process, subject to market and other conditions. There is no assurance that the initial public offering will be completed," it said.
The asset sales come as Reynolds Group faces a major debt maturity, with US$3.14b due to be repaid in 2020. Analysts questioned management at the June-quarter briefing about whether the company would re-enter the bond market to refinance, to which chief financial officer Allen Hugli said they were still working through their options.
Carter Holt Harvey - owned separately by Hart's Rank Group - sold its pulp and paper businesses to Oji Holdings for $1.04b in 2014. It toyed with the idea of listing the trans-Tasman timber processing and building supplies businesses the following year before shelving those plans.
