UnitedHealth Group and Elevance Health have both reported financial challenges in their recent earnings reports. UnitedHealth's stock dropped following a profit beat due to rising medical costs and a lowered full-year outlook. Additionally, the company's Q3 earnings revealed the impact of a cyberattack on Change Healthcare. Meanwhile, Elevance Health shares slipped in early trading after the insurer cut its annual profit forecast and reported third-quarter earnings below Wall Street expectations. The company cited unprecedented challenges in its Medicaid business and persistently high medical costs as key factors. These financial results highlight the broader issue of increasing medical expenses and high demand for healthcare services affecting the insurance sector.
