TL;DR
The financial reality of major US health insurers has decoupled from the public narrative of underwriting profits, as heavily regulated insurance margins are squeezed to near-zero or negative levels. Enterprise profitability is now sustained by routing patient volume through high-margin, unregulated vertical services, clinical networks, and specialty pharmacies. While state regulators are launching aggressive legislative campaigns to break up these integrated empires, federal courts remain a formidable shield for the industry's economic model.
The Great Margin Shift to Unregulated Vertical Services
Underwriting margins in government-sponsored health plans are collapsing under regulatory and demographic pressures, forcing conglomerates to rely on their unregulated clinical and specialty services to drive profitability.
"We continue to see 2026 as the trough year for our Medicaid margin, with improvement over time supported by better rate alignment and the maturation of our care management actions..." — Elevance Health: Carelon and the Internal Profit Engine
"As we see stronger adoption of biosimilars and specialty generics, it’s a benefit for us overall in Evernorth from a margin perspective... lower results in Pharmacy Benefit Services and higher results in Specialty and Care Services is sort of how it all comes together." — Cigna's Pivot to Evernorth and the De-Risked Commercial Employer Focus
This shift demonstrates that the traditional insurance business is increasingly becoming a low-margin pass-through. While Elevance projects a sicker-than-expected full-year Medicaid operating margin of approximately -1.75% Elevance Health: Carelon and the Internal Profit Engine, its internal services arm, Carelon, successfully offsets this drag. Similarly, Cigna is actively shifting earnings from traditional pharmacy benefit manager (PBM) rebate models to its high-margin specialty pharmacy, Accredo, which generated $1.054 billion in pre-tax adjusted operating earnings Cigna's Pivot to Evernorth and the De-Risked Commercial Employer Focus
. By capturing multiple margin points across internal delivery chains, health giants insulate their consolidated earnings from government rate cuts.
What to watch: Watch for whether other major insurers follow Cigna's lead in narrowing their exposure to volatile government risk Cigna's Pivot to Evernorth and the De-Risked Commercial Employer Focus to focus almost exclusively on commercial plans and specialty services.
State-Level Regulatory Warfare and the ERISA Shield
States are launching aggressive legislative campaigns to dismantle integrated pharmacy benefit manager structures, triggering a high-stakes legal defense centered on federal preemption.
"...the practical effect of the law was to 'requir[e] PBMs to tailor and retailor their networks — and perhaps even build new brick-and-mortar pharmacies — to comply with a set of exacting particularities...'" — PBM Vertical Integration: State Ownership Restrictions and the Tennessee Strategic Rewrite
This legal battleground highlights the tension between local policymakers trying to protect community pharmacies and conglomerates defending their integrated supply chains. In Flowers v. Caremark PCS Health, the Eighth Circuit Court of Appeals ruled that ERISA preempts state geographic network requirements, establishing a powerful precedent against local overreach PBM Vertical Integration: State Ownership Restrictions and the Tennessee Strategic Rewrite. However, the fight has escalated with Tennessee's FAIR Rx Act, which attempts to bypass federal preemption to force PBMs to divest their owned pharmacies by January 1, 2027 PBM Vertical Integration: State Ownership Restrictions and the Tennessee Strategic Rewrite
.
What to watch: Watch for the federal court's ruling on the consolidated Tennessee FAIR Rx Act litigation [PBM Vertical Integration: State Ownership Restrictions and the Tennessee Strategic Rewrite](/topics/019e89d0-893e-7d00-a5cf-ca1051e66e9d/notes/pbm-vertical-integration-state-ownership-restrictions], which will test whether states can constitutionally force the breakup of vertically integrated healthcare giants.
What surprised us
- Elevance's services arm outpaced its entire insurance business. For the first time in a non-Q4 quarter, Elevance's Carelon services division generated more operating income ($948 million) than its entire Health Benefits insurance segment ($896 million) The Managed Care Profit Engine: Vertical Integration, Services, and the Regulated Margin Myth
. This confirms that corporate survival is now entirely dependent on downstream clinical services rather than underwriting.
- Optum Insight achieved a staggering 25.3% margin. While UnitedHealth's core insurance business absorbed Medicaid losses, its technology and analytics division, Optum Insight, generated $1.4 billion in operating earnings on a massive 25.3% margin UnitedHealth and Optum Vertical Integration & Strategic Medicare Advantage Contraction
. This demonstrates that AI-enabled administrative products are becoming the industry's quiet cash cows.
- California broke through the industry's ERISA shield. In a major setback for Optum Rx and the PCMA, a federal court dismissed their challenge to California's S.B. 41 PBM Vertical Integration: State Ownership Restrictions and the Tennessee Strategic Rewrite
. By ruling that ERISA does not preempt state-imposed fiduciary duties on PBMs, the court has handed states a powerful new blueprint for regulation.
