This is the 13th annual report on the performance of portfolio companies, a group of large, private equity (PE) owned UK businesses that met defined criteria at the time of acquisition. Its publication is one of the steps adopted by the PE industry following the publication of guidelines by Sir David Walker to improve transparency and disclosure, under the oversight of the PE Reporting Group (PERG).

This report addresses many questions that various stakeholders may have on the impact of PE ownership on large UK businesses, by presenting facts and benchmarks to provide answers. The report is designed to be read stand-alone, summarising the accumulated data over the past 13 years of reporting; it also contains comparisons to last year’s results and, for some measures, shows time series trends.

This year, the report covers 61 portfolio companies as at the 2019 financial reporting year (2018: 55), as well as a further 102 portfolio companies that have been owned and exited since 2005. The findings are based on aggregated information provided on the portfolio companies by the PE firms that own them — covering the entire period of PE ownership. This year, data was received covering 53 portfolio companies, a compliance rate of 87% and a decrease from last year’s figure of 89%. On many measures of performance, the data on the current portfolio is combined with data from portfolio companies exited in 2019 and earlier, which provides over 100 data points, typically measuring performance over several years and a compliance rate of 91%.

With a large number of portfolio companies, a high rate of compliance, and thirteen years of information, this report provides comprehensive and detailed information on the effect of PE ownership on many measures of performance of an independently determined group of large UK businesses. The report comprises four sections:

• Section 1: Objectives and fact base
• Section 2: Summary findings
• Section 3: Detailed findings
• Section 4: Basis of findings
