Upstart Publishes May 2026 UMIUpstart Holdings, Inc. (NASDAQ: UPST), the leading artificial intelligence (AI) lending marketplace, today updated the Upstart Macro Index (UMI) to include May 2026 data. For historical data and information about how the index is calculated, see upstart.com/umi.UMI rose to 1.49 in May from 1.43 in April and remains below the elevated levels observed in early 2024.While UMI is derived from Upstart-powered unsecured personal loans, broader macroeconomic trends can help contextualize recent movements in the index. The personal savings rate was 3.0% in May, flat with the level in April as an increase in disposable personal income (+0.7%) was offset by an uptick in consumer spending (+0.7%). The unemployment rate was 4.3% in May, flat with the prior two months.Revisions to UMI are posted weekly. Since our last monthly data release on May 28, 2026, UMI has been revised as follows:April revised from 1.46 to 1.43March revised from 1.37 to 1.38February remained at 1.35About the UMIThe UMI estimates the impact of the macroeconomy on credit losses for Upstart-powered unsecured personal loans. UMI is expressed as a multiple of defaults relative to a static baseline due to macroeconomic changes. For example, a UMI of 1.25 for a given month suggests that the macro caused default rates to be 25% higher than the long-run average.Because Upstart’s risk models are regularly recalibrated to changing macroeconomic conditions, a UMI above 1.0 does not imply that loans are underperforming - and a UMI below 1.0 does not imply that loans are overperforming. Instead, Upstart’s risk models are regularly adjusted to conservatively account for the most recent trend in UMI. This calibration adjusts the loss assumptions and thereby the interest rates and approval rates for new loan originations on our marketplace.While we are not able to accurately forecast future macroeconomic conditions, UMI is designed to provide timely insights into how today’s macroeconomic environment impacts Upstart-powered loan portfolios.

UMI is based on historical data and Upstart’s analysis of the losses within Upstart-powered loan portfolios and is specific to Upstart’s borrower base. UMI is not intended to measure the macroeconomic risks in terms of losses of loan portfolios or asset classes that are not Upstart-powered loans, including loans held by other segments of the U.S. population. It is not designed to measure the current state of the overall economy or to measure or predict future macroeconomic conditions, trends or risks. It is also not designed to measure or predict the future performance of Upstart-powered loans or of Upstart’s other products, overall financial results of operations or stock price. We expect that our research and development efforts to improve UMI could result in changes or revisions to current or past UMI values.All forward-looking statements or information in this press release are subject to risks and uncertainties that may cause actual results to differ materially from those that Upstart expected.
