Is TransUnion overvalued or undervalued?

As of 26 September 2025, the valuation grade for TransUnion has moved from fair to expensive, indicating a shift towards overvaluation. The company appears overvalued based on its P/E ratio of 36, which is significantly higher than the industry average, and an EV to EBITDA ratio of 15.50. Additionally, the PEG ratio stands at 1.75, suggesting that the stock may not be offering sufficient growth relative to its price.
In comparison to peers, TransUnion's P/E ratio of 36 is lower than MSCI, Inc.'s risky valuation of 62.31, but still reflects a premium in the market. The EV to EBITDA ratio of 15.50 is also more favorable than MSCI's 42.54, yet still indicates that TransUnion is priced at a high multiple. Recent stock performance shows that TransUnion has underperformed against the S&P 500 across multiple periods, with a year-to-date return of -8.11% compared to the S&P 500's 12.96%, reinforcing the notion of overvaluation.
