The appointment was effective 15 November.
Ms Disher started with Cummins as director of finance for the South Pacific region in Australia in 2013.
Cummins said that Ms Disher’s leadership capability was recognised before long, resulting in her serving as the director of operations for the region and then managing director of South Pacific in 2017, based in Melbourne.
During her tenure, the business achieved record revenue and profitability growth in 2019.
Ms Disher began leading the Filtration division in August 2020, navigating the business through the pandemic and related ongoing supply chain constraints.
Through these challenges, the business, according to Cummins, consistently delivered solid financial performance.
Ms Disher has led the business as Cummins also explores strategic alternatives, a move that was announced as part of the company’s second-quarter 2021 results.
Cummins president and chief operating officer Jennifer Rumsey said: “Steph has been asked to step into increasingly challenging roles that are critical to Cummins’ continued success because of her business acumen and commitment to creating environments that foster and further our values both inside and outside of Cummins.
“She truly is a champion of our mission, vision and values, and her leadership, strategic mindset and caring nature have been incredibly important for all Filtration employees and the future opportunities for the business.”
Ms Disher has been active in Cummins’ communities, sponsoring the TEC: Technical Education for Communities program in Australia, launching the PRIDE employee resource group in the South Pacific and advocating for the power of diverse teams through her involvement with the Women’s Empowerment network.
Cummins said that prior to her career with Cummins, she excelled in roles across strategy, human resources and finance while working for BP, and as a director with Norman Disney & Young.
She was with BP for nine years, most recently as program director of strategy and integration.
Ms Disher earned a bachelor’s degree in Commerce from the University of Western Sydney and a Master of Business Administration from University of Melbourne.
She lives in Nashville, Tennessee with her husband, Brad, and their three daughters.
