S&P Global (SPGI) is moving ahead with a planned separation of its Mobility division by filing a Form 10 with the SEC for Mobility Global Inc. This step can reshape the stock’s risk and business mix.

The latest Form 10 filing and Mobility separation plan come after a period where momentum has cooled, with a 1-day share price return of 1.21% at US$428.68 but a year to date share price return of negative 16.38%. The 3 year total shareholder return of 21.93% contrasts with a 1 year total shareholder return of negative 14.88%, hinting that the market is reassessing both growth prospects and risk as S&P Global updates guidance, reports higher first quarter earnings, launches new Energy benchmarks and continues buybacks.

With shares weaker this year despite positive recent earnings and a pending Mobility spin off, the key question for you is simple: is S&P Global now trading below its true potential, or are markets already pricing in future growth?

Most Popular Narrative: 19.7% Undervalued

Based on the most followed narrative, S&P Global’s fair value of $534 sits well above the last close at $428.68, which puts the focus firmly on what is driving that gap.

The vibrant equity and debt markets in the first quarter, evidenced by strong IPO, M&A, and the highest level of debt issuance since 2021, signal a growing demand for S&P Global's ratings services, which could enhance future revenues in the Ratings division.

An increasing shift from private to public debt refinancing, propelled by issuers seeking to save up to 200 basis points on interest rates, might lead to a higher demand for public ratings and analytical solutions, positively impacting Ratings division revenue.

Want to see why this narrative leans so heavily on Ratings and new products, and how revenue, margins and future earnings multiples fit together in the model?

Result: Fair Value of $534 (UNDERVALUED)

However, this depends on supportive issuance and funding markets, and a setback in AI product returns or rising data competition could quickly challenge that underperformance narrative.

Another View: What The P/E Ratio Is Saying

The most followed narrative points to a fair value of $534, yet the current P/E of 26.6x tells a more cautious story. It sits just above the peer average of 26.3x and well above a fair ratio of 18x, which implies less room for error if growth or margins disappoint. Is this a quality premium you are comfortable paying, or a valuation gap that could close against you?
