Key Takeaways
- • The Barton Partnership's global survey of over 70 interim CFOs across the UK and US reveals that interim financial leaders have become execution-focused operators driving value creation, operational stabilization, and finance transformation across PE-backed portfolios.
- • Nearly half (49%) of interim CFOs surveyed have five or more years of experience in the role, establishing a mature, PE-experienced talent pool rather than a first-time consultant market; nearly all appointments involved direct PE sponsor involvement.
- • Finance function rebuilding is widespread, with 80% of interim CFOs reporting active hiring and restructuring of finance teams during their engagements, primarily to strengthen reporting capabilities, FP&A infrastructure, and cash flow visibility.
- • PE sponsors are deploying interim CFOs with increasing frequency to navigate complexity post-investment, particularly when portfolio companies face data gaps, liquidity pressures, or require significant transformation initiatives.
- • The research indicates a fundamental shift in how private equity deploys financial leadership as deal timelines extend and operating conditions tighten, positioning interim CFOs as critical leadership decisions rather than temporary support functions.
Summary
The Barton Partnership released a global research report on May 18, 2026, examining the evolving role of interim CFOs within private equity-backed businesses. Drawing on a survey of over 70 interim CFOs across the UK and US markets, the report documents a material shift in how PE sponsors deploy senior financial leadership, moving beyond traditional interim support toward execution-oriented value creation roles.
The research reveals that today's interim CFO cohort comprises highly experienced operators. Nearly half of survey respondents have served five or more years in interim CFO capacities, indicating a sophisticated, mature market of PE-familiar financial leaders rather than a pool of first-time consultants. This experience profile reflects PE sponsors' confidence in interim executives to navigate complex portfolio situations. Notably, nearly all interim CFO appointments involved direct sponsor involvement in the hiring decision, underscoring the strategic importance placed on these roles within deal execution and value creation strategies.
Finance function rebuilding emerges as a widespread and material engagement activity. Eighty percent of interim CFOs surveyed reported actively hiring into finance functions during their tenures, often restructuring teams to enhance reporting infrastructure, financial planning and analysis (FP&A) capabilities, and cash flow visibility. This pattern indicates that PE sponsors are using interim CFO deployments not merely to stabilize existing finance operations but to fundamentally reshape financial capabilities aligned with value creation timelines and sponsor performance expectations.
The report attributes increased reliance on interim CFOs to several operating pressures. PE sponsors are deploying interim financial leaders to manage complexity in post-investment periods, particularly in situations involving data gaps, liquidity constraints, or substantial transformation initiatives. As deal timelines extend and operating conditions tighten, interim CFOs function as experienced hands providing immediate stabilization while executing medium-term finance transformation agendas.
