The Obesity Drug Boom: Evernorth’s Coverage Expansion Fuels a $10 Billion Market Opportunity

The global obesity crisis is no longer a silent emergency—it’s a $10 billion market opportunity by 2030, and Evernorth’s new pharmacy benefit for weight loss medications is primed to accelerate this trajectory. By dismantling financial and logistical barriers to GLP-1 receptor agonists (GLP-1s), such as Wegovy and Zepbound, the initiative could supercharge adoption rates while creating strategic advantages for insurers and pharmaceutical giants like Novo Nordisk (NVO) and Eli Lilly (LLY). But beneath this growth lies a volatile landscape of pricing pressures and regulatory risks that investors must navigate.

The Catalyst: Evernorth’s Groundbreaking Coverage Model

Evernorth’s EnReachRx program, launching this June, is a masterstroke in addressing two critical pain points: patient affordability and clinical adherence. By capping copays at $200/month for GLP-1s—versus $600/month in direct-to-consumer plans—and integrating specialized pharmacies like EnGuide, the program slashes out-of-pocket costs by 67% while providing education, adherence tracking, and fraud prevention. This isn’t just a cost-saving measure; it’s a demand multiplier.

Consider the data:
- GLP-1 utilization for weight loss is projected to surge 73% by year-end .
- Over 24% of consumers are now considering these drugs, while 65% of providers are ready to prescribe them.
- Youth adoption is exploding, with Gen Alpha (ages ≤14) seeing an 84.6% increase in usage since 2023—a demographic shift that hints at lifelong drug dependency.

For NVO and LLY, this is a gold rush. Their flagship drugs, Wegovy and Zepbound, are now accessible to millions of newly insured patients. Evernorth’s program ensures these therapies aren’t confined to the wealthy, unlocking a broader market.

Winners: NVO and LLY Lead the GLP-1 Gold Rush

The financial implications for these drugmakers are staggering. Evernorth’s $200 copay cap effectively transfers the burden of high list prices ($1,200/month) to insurers and employers—but with a catch. By improving adherence and reducing discontinuation (currently over 50% within 12 months), the program ensures patients stay on therapies long enough to justify the cost. This creates a virtuous cycle:

1. Volume Growth: Lower copays → more patients enrolled → higher drug sales.
2. Brand Loyalty: Clinical support and adherence programs → reduced switching to generics or biosimilars.
3. Market Penetration: Youth adoption → lifetime customers for NVO/LLY.

Analysts project NVO’s obesity drug sales alone could hit $8 billion annually by 2030, while LLY’s share could triple as it expands indications for Mounjaro into cardiovascular and Alzheimer’s therapies.

The Strategic Edge for Insurers and PBMs

Evernorth’s move isn’t altruistic—it’s a strategic play to dominate the obesity therapeutics space. By bundling GLP-1 access with fraud detection, adherence tools, and $0 out-of-pocket biosimilars for other drugs, the PBM reduces long-term healthcare costs. For example, a diabetic patient on GLP-1s may avoid costlier complications like heart disease or amputations. This total cost of care approach is why Evernorth’s specialty division saw a 19% YoY revenue jump in Q1 2025.

Insurers gain a competitive moat:
- Differentiation: Offering “wellness” programs that rival workplace gyms.
- Cost Predictability: Financial guarantees like EncircleRx (saving $200M since 2024) insulate them from GLP-1’s volatile pricing.
- Regulatory Alignment: Supporting FDA’s push to curb youth obesity while managing liability risks.

The Risks: A Volatile Landscape Ahead

The path isn’t without pitfalls. Three critical threats loom:

1. Pricing Pressure:
2. Biosimilar competition could erode margins. Evernorth’s success with Stelara biosimilars ($0 copays) signals a playbook for GLP-1s.

3. The Biden administration’s Most Favored Nation (MFN) rule, now delayed but still a threat, could cap Medicare prices.

4. Regulatory Scrutiny:

5. FDA restrictions on youth use could limit Gen Alpha/Gen Z adoption.

6. State-level price controls, like those in California, may pressure insurers to cap reimbursements.

7. Adherence Challenges:

8. Side effects (nausea, diarrhea) and high discontinuation rates remain barriers. Evernorth’s adherence programs may mitigate this, but success hinges on execution.

Investment Thesis: Act Now—But Stay Vigilant

The data is clear: Evernorth’s initiative is a tipping point for the obesity drug market. NVO and LLY are positioned to dominate, but investors must balance growth with risk.

• Buy NVO and LLY: Their pipelines extend beyond weight loss—LLY’s Alzheimer’s trials for donanemab and NVO’s cardiovascular data are game-changers.
• Monitor Evernorth’s parent, Cigna (CI): Its Q1 net profit of $1.3B (vs. a $277M loss in 2024) shows the upside of PBM innovation.
• Watch for biosimilar threats: Companies like Samsung Bioepis (notably absent from U.S. markets yet) could disrupt pricing.

Conclusion

Evernorth’s coverage expansion is a once-in-a-decade opportunity to profit from a public health crisis turned into a financial boom. While risks like pricing caps and regulatory shifts are real, the demand for GLP-1s is undeniable. For investors, this is a call to act decisively—but stay informed. The obesity market’s $10 billion future is here, and the winners are already in motion.
