UnitedHealth Crashes 20%, Intellia Hold Lifted | Jan 2026
A structural repricing of the managed care sector (-20% UNH) following disappointing Medicare Advantage rates and new “TrumpRx” policy signals has triggered an immediate sector-wide rotation. This macro capitulation is overshadowing a critical regulatory win for Intellia’s CRISPR platform, which cleared a major safety hurdle Tuesday morning.
The managed care sell-off is not a single-stock event. UnitedHealth’s 20% crash, Humana’s 20%+ decline, and double-digit drops across CVS and Elevance signal that the “Golden Era” of Medicare Advantage margin expansion is effectively over. At the same time, Intellia’s partial hold lift on MAGNITUDE-2 creates a clearing event for the CRISPR platform—though the remaining cardiomyopathy hold keeps the valuation discount alive.
What To Watch
Managed Care Contagion
UnitedHealth’s 19.6% drop and forward guidance cut is forcing an immediate repricing of Humana (HUM), CVS, Centene (CNC), and Elevance (ELV). The proposed 0.09% Medicare Advantage rate increase for 2027—versus analyst expectations of 4-6%—is a systemic signal, not a company-specific miss. Expect volatility in provider chains (e.g., HCA) despite earnings beats, as the market prices in tougher reimbursement cycles ahead.
CRISPR Safety Re-rating
Intellia’s hold lift on the polyneuropathy arm (MAGNITUDE-2) is a “clearing event” for the platform, demonstrating FDA alignment on enhanced safety monitoring. But the remaining hold on the cardiomyopathy arm (MAGNITUDE) keeps the safety overhang—and valuation discount—alive. Watch for update on ATTR-CM path forward.
Medtech Consolidation Accelerates
Boston Scientific’s pending $14.5B acquisition of Penumbra (announced Jan 15) is accelerating competitive dynamics in thrombectomy. Penumbra’s Lightning Flash 3.0 launch represents the final major product cycle refresh before deal close. Watch for counter-moves from Medtronic or Stryker in the neurovascular space.
Top Story: UnitedHealth Crashes on Rate Shock & Revenue Warning
What Happened: UnitedHealth Group (UNH) shares plummeted nearly 20% Tuesday after the company cut its 2026 revenue guidance and CMS released a lower-than-expected Medicare Advantage rate proposal (0.09% increase vs. expected 4-6%). The stock fell from approximately $352 to below $285—one of the steepest single-day declines in company history.
UNH reported Q4 2025 revenue of $113.2 billion (up 12% YoY but below consensus of $113.7B) and guided 2026 revenue to “greater than $439 billion”—a 2% year-over-year decline that would mark the company’s first annual revenue drop in over three decades. Full-year adjusted medical care ratio rose to 88.9%, up 340 basis points from 2024, reflecting persistent cost pressures.
Why It Matters: This is a systemic signal that the “Golden Era” of Medicare Advantage margin expansion is effectively over. The administration’s aggressive stance on rates, combined with new HHS/OIG guidance facilitating Direct-to-Consumer (DTC) models (“TrumpRx”), suggests a coordinated policy squeeze on traditional payer profit pools.
The contagion was immediate: Humana dropped 20%+, CVS shed 13%, Elevance fell 13%, and Centene dropped 10%+. With UNH representing roughly 30% of national Medicare Advantage enrollment and Humana at 17%, the rate proposal affects the entire managed care sector.
UNH Earnings Summary
Q4 2025 Revenue: $113.2B (up 12% YoY, missed consensus) | FY2025 Revenue: $447.6B | 2026 Revenue Guidance: >$439B (2% decline) | Medical Care Ratio: 88.9% (up 340bps YoY) | 2026 EPS Guidance: >$17.75 | Stock Move: -19.6%
Executive Impact
Strategy teams at payers must immediately stress-test 2026 operating margins. Provider networks may face tougher contract negotiations as payers pass down pressure. The “V29” risk adjustment changes flagged by analysts could further slow any rebound in Medicare Advantage and Value-Based Care economics.
CRISPR Platform Clears Safety Hurdle: Intellia MAGNITUDE-2 Hold Lifted
What Happened: Intellia Therapeutics announced Tuesday that the FDA has removed the clinical hold on the MAGNITUDE-2 Phase 3 trial of nex-z for hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN). The company plans to resume patient enrollment and dosing with enhanced liver safety monitoring protocols.
The clinical holds on MAGNITUDE (cardiomyopathy) and MAGNITUDE-2 (polyneuropathy) were imposed by FDA on October 29, 2025, following a Grade 4 liver transaminase event in a patient dosed in MAGNITUDE. Intellia has now aligned with FDA on study modifications for MAGNITUDE-2, including enhanced monitoring of liver laboratory values. Target enrollment has been increased from approximately 50 to 60 patients.
Why It Matters: This is a partial clearing event for the CRISPR platform. The polyneuropathy arm can now proceed, demonstrating that FDA found Intellia’s risk mitigation measures acceptable. However, engagement remains ongoing for the MAGNITUDE trial in ATTR-CM—the larger commercial opportunity—which keeps the safety overhang and valuation discount partially intact.
NTLA shares jumped approximately 25% in pre-market trading on the news, reflecting the market’s relief that at least one pivotal program can advance.
Intellia MAGNITUDE-2 Trial
Indication: ATTRv-PN (hereditary ATTR with polyneuropathy) | Design: Randomized, double-blind, placebo-controlled | Dose: Single 55mg infusion | Enrollment: ~60 patients (increased from ~50) | Primary Endpoints: Modified neuropathy impairment score, serum TTR levels | Hold Status: Lifted (MAGNITUDE-2); Ongoing (MAGNITUDE/ATTR-CM)
Oncology & Rare Disease
J&J / Genmab: Darzalex Faspro Approved for Transplant-Ineligible Myeloma
Approval: FDA approved Darzalex Faspro + VRd (bortezomib, lenalidomide, dexamethasone) for newly diagnosed multiple myeloma patients ineligible for autologous stem cell transplant. This is the 12th indication for Darzalex Faspro and the 5th in newly diagnosed myeloma.
Data: The Phase 3 CEPHEUS trial showed a 52.3% MRD negativity rate vs. 34.8% for VRd alone at 22 months (P<0.0005). At 39 months, sustained MRD-negativity of ≥12 months nearly doubled: 42.6% vs. 25.3%. D-VRd reduced risk of progression or death by 40% (HR 0.60). At nearly 5 years, complete response or better was 81.2% vs. 61.6%.
Context: D-VRd is now the only anti-CD38 antibody-based regimen with approved indications across newly diagnosed patients regardless of transplant eligibility, cementing the quadruplet regimen as the standard of care. This is the first FDA-approved regimen based on a study with MRD-negativity as the primary endpoint.
StarkAge Therapeutics: Senolytic ADC Deal
Deal: Announced collaboration with Gustave Roussy to advance STX-1, a senolytic Antibody-Drug Conjugate targeting DPP4 in digestive cancers.
Signal: Senolytics are moving from “longevity” science into hard oncology indications. Validation from a major European cancer center adds translational credibility to the mechanism.

Penumbra: Lightning Flash 3.0 Launch
Rolled out the Lightning Flash 3.0 mechanical thrombectomy system, claiming 1.3x faster clot removal. This is the final major product cycle refresh prior to the expected close of its $14.5B acquisition by Boston Scientific in H2 2026.
Policy & Public Health
HHS/OIG Guidance: Direct-to-Consumer Models
The HHS Office of Inspector General issued new guidance clarifying how manufacturers can offer lower-cost drugs directly to patients (bypassing PBMs) without violating anti-kickback statutes.
Strategic Read: This aligns with the administration’s “TrumpRx” initiative to dismantle PBM leverage. Expect a rise in manufacturer-direct cash pay models for high-volume generics and insulin. Combined with the Medicare Advantage rate squeeze, this signals a coordinated policy assault on traditional payer and PBM profit pools.
The Repricing Has Begun
Tuesday’s managed care rout is not a single-earnings miss—it’s a structural repricing of an entire sector. The combination of flat Medicare Advantage rates, rising medical cost ratios, and new DTC policy signals has fundamentally reset investor expectations for payer economics in 2026 and beyond.
Meanwhile, Intellia’s partial hold lift demonstrates that even amid platform-level safety concerns, regulatory engagement and risk mitigation can create clearing events. The bifurcated outcome—polyneuropathy proceeds, cardiomyopathy remains on hold—is a template for how these complex situations resolve: incrementally, with continued overhang until full clarity emerges.
For healthcare investors, the message is clear: macro policy risk is now the dominant factor in managed care, while execution on safety protocols remains the gating variable for gene editing platforms.

Frequently Asked Questions
Why did UnitedHealth stock crash 20%?
UNH fell nearly 20% due to two factors: CMS proposed a 0.09% Medicare Advantage rate increase for 2027 (versus expected 4-6%), and UNH guided 2026 revenue to decline 2% YoY—the company’s first annual revenue drop in over 30 years. The medical care ratio also rose to 88.9%, up 340 basis points from 2024.
What is the Medicare Advantage rate proposal for 2027?
CMS proposed a net average payment increase of just 0.09% for Medicare Advantage plans in 2027. Analysts had expected 4-6% increases. If finalized in April, this would result in approximately $700 million more in payments—far below what insurers need to maintain current margins given rising medical costs.
What is Intellia’s MAGNITUDE-2 trial?
MAGNITUDE-2 is a Phase 3 trial evaluating nex-z, Intellia’s CRISPR-based gene editing therapy, in patients with hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN). The FDA lifted the clinical hold on this trial on January 27, 2026, allowing enrollment to resume with enhanced safety monitoring.
Why was Intellia’s trial on clinical hold?
FDA placed clinical holds on MAGNITUDE and MAGNITUDE-2 on October 29, 2025, after a patient in MAGNITUDE experienced Grade 4 liver transaminase elevations and increased total bilirubin. Intellia has now aligned with FDA on enhanced liver safety monitoring for MAGNITUDE-2, but the MAGNITUDE (cardiomyopathy) hold remains in place.
What is the difference between MAGNITUDE and MAGNITUDE-2?
MAGNITUDE is the Phase 3 trial for ATTR-CM (cardiomyopathy)—the larger commercial opportunity with 650+ patients enrolled. MAGNITUDE-2 is for ATTRv-PN (polyneuropathy) with approximately 50-60 patients. The hold was lifted only for MAGNITUDE-2; MAGNITUDE remains on hold pending further FDA engagement.
What did the Darzalex Faspro approval add?
FDA approved Darzalex Faspro + VRd for newly diagnosed multiple myeloma patients ineligible for transplant. The CEPHEUS trial showed 52.3% MRD-negativity vs. 34.8% for VRd alone, and 40% reduction in progression or death risk. This is the 12th indication for Darzalex Faspro.
What is medical cost ratio (MCR) and why does it matter?
Medical cost ratio measures the percentage of premium revenue spent on medical claims. UNH’s MCR rose from 85.5% in 2024 to 88.9% in 2025, meaning the company is spending $0.89 of every premium dollar on care. Rising MCR signals margin compression and is a key indicator of payer profitability pressure.
What is the TrumpRx initiative?
TrumpRx refers to the administration’s policy push to dismantle PBM leverage and enable manufacturer-direct drug pricing. The new HHS/OIG guidance clarifies how manufacturers can offer lower-cost drugs directly to patients without violating anti-kickback statutes, potentially bypassing traditional PBM channels.
What is Boston Scientific acquiring Penumbra for?
Boston Scientific announced on January 15, 2026 that it will acquire Penumbra for approximately $14.5 billion ($374/share). The deal gives Boston Scientific scaled entry into mechanical thrombectomy and neurovascular markets. Penumbra’s Lightning Flash thrombectomy systems are used to remove blood clots in stroke, pulmonary embolism, and DVT.
How did other managed care stocks perform?
The sector sold off broadly: Humana (HUM) dropped 20%+, CVS fell 13%, Elevance (ELV) declined 13%, and Centene (CNC) dropped 10%+. The contagion reflects the systemic nature of the Medicare Advantage rate proposal, which affects all major MA insurers.
