Is Gartner, Inc. overvalued or undervalued?

As of 17 October 2025, Gartner, Inc. moved from fair to very attractive in its valuation grade. The company appears undervalued, particularly when considering its P/E ratio of 64, which is significantly higher than its peer CoStar Group, Inc. at 381.24 and Check Point Software Technologies Ltd. at 53.34. Additionally, Gartner's EV to EBITDA ratio stands at 48.11, while its PEG ratio is 2.22, indicating a potential for growth relative to its valuation.
In comparison to its peers, Gartner's valuation metrics suggest it is positioned favorably against companies like VeriSign, Inc. with a P/E of 33.05 and CoStar Group, Inc. with a P/E of 381.24. Despite recent underperformance, with a year-to-date return of -51.34% compared to the S&P 500's 13.30%, the strong return over the last five years of 81.23% suggests that Gartner may still hold long-term value.
