Nine months after taking charge of BlueScope, Tania Archibald has delivered her first major piece of good news. On Monday 26 October the steelmaker said it now expects underlying earnings before interest and tax for the first half of FY2027 to be approaching $1.1 billion, above its previous guidance range of $860 million to $960 million.

The upgrade

“The increase is primarily driven by stronger than anticipated earnings from North Star on stronger US steel spreads, along with improved performance at Buildings and Coated Products North America and Australian Steel Products,” Ms Archibald said.

BlueScope now expects its North Star mini-mill in the United States to deliver a result approaching three-quarters higher than the second half of FY2026, with benchmark US mini-mill spreads for the half now expected to be around US$810 a tonne, against the roughly US$750 assumed in earlier guidance. The North America region as a whole is expected to be around two-thirds higher.

“Conditions across the US steel industry and in our key North American end-use markets remain favourable, and the United States continues to demonstrate why it is such an attractive place to make and sell steel,” she said.

A home-grown chief

Ms Archibald became BlueScope’s managing director and chief executive on 1 February 2026, succeeding Mark Vassella, who retired after eight years in the role. At the time, chair Jane McAloon described her as “a highly capable executive who has demonstrated outstanding leadership over the course of her 30-year career at BlueScope”, and the fourth chief executive since BlueScope listed on the ASX.

Her rise has been through the numbers and the plants. According to BlueScope, she was chief executive of Australian Steel Products from 2023 to 2026, leading the company’s Australian operations including Port Kembla in NSW and Western Port in Victoria, and was chief financial officer from 2018 to 2023, when she was also a director of the NS BlueScope joint venture with Nippon Steel. Earlier roles included CFO of BlueScope ANZ and positions in strategy, business development and corporate finance, with finance leadership roles in Vietnam and Indonesia. She holds a Bachelor of Economics and is a chartered accountant.

Her old business, too

The upgrade also reflects the division she ran until this year. BlueScope expects Australian Steel Products to deliver earnings approaching double those of the second half of FY2026, on resilient domestic demand, stronger despatch volumes and better realised spreads. “We have also seen a stronger then expected performance from Australian Steel Products, driven by resilient domestic demand and higher value-added sales,” Ms Archibald said.

Next up

“While market conditions remain dynamic, the performance we’ve seen through the first half reinforces our confidence in the strength of BlueScope’s portfolio, the quality of our assets and our continued ability to deliver strong shareholder returns,” she said. Shareholders will hear more at BlueScope’s annual general meeting in Wollongong and online on 16 November, where the company has said it will provide further detail on operating conditions.
