10 Most Undervalued Healthcare Stocks to Buy According to Analysts

4. UnitedHealth Group Incorporated (NYSE:UNH)

Analyst Upside: 426.48 

UnitedHealth Group Incorporated (NYSE:UNH) is among the most undervalued stocks. It is the largest U.S. health insurer, operating through its insurance arm (UnitedHealthcare) and health services division (Optum). It serves over 50 million people and continues to focus on transforming care delivery through value-based care, integrated services, and investments in social determinants of health.

In May 2025, Stephen J. Hemsley returned as CEO, replacing Andrew Witty. The leadership shift comes amid uncertainty, with the company withdrawing its 2025 financial outlook but reaffirming its long-term goals of improving healthcare access, quality, and affordability.

UNH is expanding care access, particularly for underserved and rural populations. Through the UnitedHealth Foundation, the company partnered with Cherokee Health Systems to improve rural prescription delivery. It also committed $7 million in grants to maternal and infant health, and its affordable housing-linked health investments reached $1.2 billion. A major project in Minneapolis will include 83 housing units and a new health center expected to serve 3,000 additional patients annually.

For 2025, UnitedHealth Group Incorporated (NYSE:UNH) introduced 140 new Medicare Advantage plans, expanding support for chronically ill and dual-eligible populations. The Chronic Special Needs Plans (C-SNPs) will significantly increase coverage. Optum plans to serve 650,000 more patients under value-based care, leveraging AI tools to enhance coordination and preventive care.

Optum is deepening its home-care services following its 2023 acquisition of LHC Group and now aims to acquire Amedisys. If approved, the deal would give Optum major market share in several states. However, the Department of Justice is reviewing the merger for potential antitrust violations.
