Is TransUnion overvalued or undervalued?

As of 3 October 2025, the valuation grade for TransUnion has moved from fair to expensive, indicating a shift towards overvaluation. The company is considered overvalued, particularly when analyzing its key ratios: the P/E ratio stands at 36, the Price to Book Value is 3.94, and the EV to EBITDA is 15.50. In comparison, its peer MSCI, Inc. has a significantly higher P/E ratio of 62.31, suggesting that TransUnion may not justify its current valuation relative to its peers.
Additionally, the company's recent stock performance has been underwhelming, with a year-to-date return of -16.58% compared to the S&P 500's positive return of 14.18%. This stark contrast reinforces the notion that TransUnion's current valuation may not be sustainable in light of its recent performance and relative metrics.
