Smurfit Westrock said it expects to make a full year core profit of $4.7 billion after posting third quarter earnings before interest, tax, depreciation and amortisation (EBITDA) of $1.265 billion.
Smurfit Westrock is the world's largest cardboard box maker.
Today marks the first time Smurfit Westrock has reported results as a combined company since Smurfit Kappa, the largest paper packaging producer in Europe, completed its $11 billion acquisition of US rival WestRock in July.
The company reported net sales of $7.7 billion for the third quarter and a net loss of $150m, which it said was mainly due to transaction related expenses and purchase accounting adjustments totalling approximately $500m.
Tony Smurfit, the company's president and CEO, said the company's third quarter performance was "excellent".
"Our third quarter performance, combined with our deeper knowledge of the combination and continuing asset optimisation, clearly points to the opportunities ahead for Smurfit Westrock," Mr Smurfit said.
"We are at the start of our journey to build the 'go-to' sustainable packaging partner of choice, a global leader with an unrivalled scale, geographic reach and product portfolio," he said.
"Having spent the last number of months visiting our plants, it is also clear that our people are excited and motivated to be a part of this journey," he added.
"We expect 2024 full year combined adjusted EBITDA of approximately $4.7 billion and we are increasingly excited by our immediate and longer-term prospects," Tony Smurfit stated.
