S&P Global Shares Plunge on Softer Earnings Forecast and Profit Warning

Shares of S&P Global Inc. (SPGI) plunged sharply after the company issued 2026 profit guidance below Wall Street expectations, triggering a broad sell-off in the stock and wider data/analytics sector. According to reports, SPGI’s stock fell nearly 18 % in premarket trading, dragging the share price lower after the company forecast adjusted earnings below consensus and posted mixed fourth-quarter results.

Investors reacted negatively to the softer outlook, with the stock off a large percentage year-to-date prior to the announcement, reflecting growing concerns about slowing demand in traditional financial data services, increasing competition and macro pressures impacting corporate spending. The forecast missed consensus estimates despite revenue growth in the most recent quarter — a dynamic that highlighted investor sensitivity to future profit acceleration. Bloomberg reported that the broader software and analytics sector has been under pressure, partly due to fears that AI advancements could disrupt traditional data intelligence models and margins.

Market Implication: The sharp drop in S&P Global shares underscores valuation risk in established data/analytics firms, especially as investors weigh shifting demand patterns, potential AI disruption and more cautious earnings momentum.
