Resilient, private equity-backed middle market companies demonstrated steady growth in revenue and EBITDA year-over-year.
The Golub Capital Altman Index can provide early insight into financial performance of public companies in advance of earnings season.
NEW YORK, July 14, 2026 – Middle market private companies in the Golub Capital Altman Index grew revenue by 3.1% year-over-year in the first two months of the second quarter of 2026. Earnings grew by 3.7% year-over-year during the same period.
Lawrence E. Golub, Co-CEO of Golub Capital, said, “Our early read on second quarter results is encouraging. Despite higher oil prices and uncertainty related to the Iran conflict, middle market companies in our sample delivered steady growth in both revenue and EBITDA. We were particularly encouraged by the continued strength of our enterprise software companies. Our data suggests that mission-critical software providers with strong market share and durable customer relationships continue to perform well. More broadly, these results are consistent with an economy that continues to demonstrate resilience.”
Dr. Edward I. Altman said, “One notable finding from this quarter’s data is that earnings growth kept pace with revenue growth. This suggests that companies in our sample generally were able to maintain profit margins despite the inflationary pressures that emerged during April and May. We were also encouraged by the performance of Consumer companies. In last quarter’s report, we highlighted the possibility that higher gasoline prices could create a headwind for consumer spending. While we remain mindful of the risks associated with higher energy costs and geopolitical uncertainty, our Consumer-sector data suggests that those concerns had not yet materially affected operating performance during the period covered by this report.”
The Golub Capital Altman Index (“GCAI”), which is produced by Golub Capital in collaboration with credit expert Dr. Edward I. Altman, is the first and longest-running index based on actual revenue and earnings (defined as earnings before interest, taxes, depreciation and amortization, or “EBITDA”) for middle market companies. It measures the median revenue and earnings growth of approximately 110–150 private U.S. companies in the loan portfolio of Golub Capital, a leading middle market lender.
The size and diversity of the Golub Capital loan portfolio ensure that the confidentiality of all company-specific information used in the index is maintained in both the aggregate and industry segment data.
We believe the results (1) are representative of the general performance of middle market companies, which are a major contributor to U.S. private sector employment; (2) are relevant to the aggregate economic performance of the U.S. economy; and (3) provide timely information for the investment community.
Effective January 1, 2026, Golub Capital enhanced its data collection capabilities, providing for more comprehensive data from an expanded sample of GCAI constituents. We believe our enhanced data collection capabilities increase data quality and strengthen the analytical rigor of future reports. Backtesting has confirmed historical comparability. The companies in the GCAI operate in a wide range of industries. Results are provided for the total universe of GCAI constituents and by certain industry segments.
