As Q4 2025 earnings season wraps up, VMG Health observed some key themes from the publicly traded payers’ and hospital providers’ earnings calls and releases. As regulatory and reimbursement pressures intensify, operators, payers, and providers must make strategic adjustments to weather the impacts downstream.
Theme #1: Regulatory Headwinds
Over the prior 12 months, legislative reforms and proposed policy changes from the Centers for Medicare & Medicaid Services (CMS) aimed to address cost-containment needs at the government level. CMS Administrator Mehmet Oz, MD (Dr. Oz) has emphasized modernization initiatives centered on tightening payment accuracy and expanding site-neutral reimbursement. Recent ACA exchange redeterminations and legislative reforms tied to H.R. 1 further reinforce this tightening environment. Medicaid work requirements and more frequent eligibility redeterminations aim to moderate federal spending growth, but these changes risk increasing coverage churn and exposure to uncompensated care. As a result, payers and providers alike are seeking ways to mitigate potential compression on the top and bottom line.
On January 26, CMS released its 2027 Medicare Advantage (MA) Advance Notice, which included a proposed rate update of 0.09%. The following day, UnitedHealth Group reported its Q4 2025 earnings. During the earnings call, Tim Noel, CEO of UnitedHealthcare, stated: “The Advance Notice published yesterday simply doesn’t reflect the reality of medical utilization and cost trends.”
Humana management relayed a similar concern over the proposed rate during their Q4 2025 earnings call, but preferred to wait until finalization to provide additional commentary.
Viewed in this context, UnitedHealth Group’s calendar year (CY) 2026 revenue guidance reduction is particularly notable, especially considering the company’s prior record of steadily increasing projections. While management attributed the forecast cut to “planned right‑sizing across the enterprise,” the shift aligns with mounting pressures from MA funding reductions and membership declines (in an effort to stabilize margin), implying that the regulatory environment may weigh more heavily on performance than their high-level public commentary reflects.
Provided CY 2026 guidance figures from hospital operators also considered impacts of the recent regulatory changes, particularly ACA exchange redeterminations. For example, Community
Health Systems reported that a 20% reduction in fixed volumes resulted in a $100–$120M reduction in net revenue guidance and a $20–$30M reduction in EBITDA guidance for 2026. This decline is primarily driven by projected enrollment churn within the ACA exchanges, as the expiration of enhanced premium tax credits and tighter eligibility standards under the current regulatory landscape are expected to significantly reduce exchange volumes. HCA management similarly noted, “an adverse impact on adjusted EBITDA between $600 million and $900 million related to health insurance exchanges, [which] includes impact from administrative reforms enacted in 2025.”
Universal Health Services provided similar projections, but CFO Steve Filton noted:
“All the hospital companies have made estimates about what’s going to happen with the exchanges, but the truth is we’re going to need a few more months to really see how this sorts out, what the real loss in volume is, how many of these people who lose their exchange coverage can get other coverage.”
Additionally, while not yet quantified publicly, proposed legislative changes tied to H.R. 1 have the potential to further exacerbate the potential coverage losses expected from ACA redeterminations.
Theme #2: Planning & Resilience
Major operators have already begun detailing initiatives to address these proposed regulatory changes to both limit their impact and promote growth and efficiency in this evolving healthcare landscape. To remain resilient in the face of the proposed government headwinds, UnitedHealth Group and Humana reiterated their commentary on improving operational efficiency.
Stephen Hemsley, CEO of UnitedHealth Group, detailed their plans to leverage “thoughtful application of modern intelligent technologies, [which] can help address long-standing needs in healthcare for simplicity, speed, certainty, insight, consumer empowerment and convenience.”
Similarly, Celeste Marie Mellet, CFO of Humana, detailed “broader transformation efforts to increasingly impact results beginning this year. This includes expanding outsourcing capabilities, simplifying and standardizing processes, and leveraging technology and automation.”
In HCA Healthcare’s Q4 2025 earnings call, management unveiled a multi-year “Resiliency Program,” targeting $400M of savings in 2026. The initiative focuses on four key areas:
- Revenue integrity
- Variable- and fixed-cost efficiencies and capacity management supported by benchmarking and advanced analytics
- Digital transformation through AI and automation
- Expanded leverage of the company’s shared services platforms
Tenet Healthcare Corporation Chairman and CEO Saum Sutaria noted that the company is approaching “expense management more structurally,” signaling a strategic shift toward sustainable cost transformation. This approach reflects an increased emphasis on technological advancement, operational efficiency, and improved clinical throughput to drive long-term cost reduction and performance improvement.
On the nonprofit side, Ascension CEO Eduardo Conrado’s recently told Becker’s Hospital Review that rising uninsured volumes from ACA exchange subsidies and H.R. 1 underscore a structural shift rather than a temporary disruption, prompting a broader “operating reset.”
Theme #3: Outpatient Strategy for Growth
Underscored by Dr. Oz’s focus on expanding site-neutral reimbursement, a consistent theme emerging from Q4 2025 earnings call commentary is a steady and increasingly deliberate shift toward outpatient care as a foundation for long‑term growth. During Tenet Healthcare Corporation’s Q4 2025 earnings call, CEO Saum Sutaria noted:
“The continued mix shift of services towards lower-cost sites of care will be furthered by the beginning of the phase-out of the inpatient-only list in 2026; we see this as a gradual tailwind for USPI that will play out over several years.”
As procedural volumes are expected to migrate over time to lower-cost settings, Tenet continues to position its portfolio to participate in that shift.
HCA Healthcare highlighted similar capital priorities. With projected 2026 capital spending of $5–$5.5B, the company identified ongoing outpatient facility expansion as a central strategic priority to support volume growth and diversify revenue streams. Specifically, CEO and Director Sam Hazen stated that today HCA has “about 2,700 outpatient facilities or so, [which] continues to grow, and we see that pushing toward [HCA’s] targets of 18 to 20 outpatient facilities per hospital as we finish out this decade.” HCA currently has 190 hospitals, implying 720–1,100 new outpatient facilities over the next five years.
Nonprofit systems appear to be echoing this approach. CommonSpirit Health has repeatedly emphasized ambulatory care as a strategic focal point. According to CEO Wright Lassiter during the 44th Annual J.P. Morgan Healthcare Conference, “We’ll also be looking very aggressively at how we augment our portfolio, particularly around ambulatory care.” In its quarterly report, the system described “working to identify diversified revenue opportunities that expand CommonSpirit from a heavier weighting in acute care, to quickly scale critical ambulatory services,” while continuing to “expand its ambulatory and virtual care points and enhance connections across the continuum of care.”
Ascension represents one of the most tangible examples of this shift. Its agreement to acquire AmSurg will “add more than 250 ambulatory surgery centers across 34 states.” At the 44th Annual J.P. Morgan Healthcare Conference and follow-up interviews, CEO Eduardo Conrado highlighted that the acquisition will allow Ascension to “capture and serve more patients, shift low-acuity cases out of the hospital to sites that are lower cost and often preferred by patients,” adding, “the ambulatory space has a 10%-plus CAGR going forward.”
Across the industry, the emphasis is less about replacing hospitals and more about complementing them through broader access, alignment with site‑of‑care trends, and a more diversified delivery platform for the years ahead.
Conclusion
While the industry faces regulatory and reimbursement pressures, operators have focused on mitigating plans and opportunities for future growth to offset long-term impacts. Payers and providers alike are navigating simultaneous regulatory tightening, reimbursement pressure, and rising coverage volatility. As a result, fiscal discipline and a pivot toward future growth opportunities, such as ambulatory care, are becoming a strategic necessity in context of a rolling long-range financial plan
For organizations facing this ever-changing environment, the challenge is not simply understanding these shifts; it’s planning, modeling, and executing them. Organizations must quantify financial exposure, evaluate alternative care-delivery models, and evaluate how capital should be deployed across inpatient, outpatient, and emerging sites of care. Without an organized and fiscally sound approach to ambulatory migration, organizational inertia remains significant, with many investment, hiring, and other strategic decisions deferred or delayed.
Whether rebalancing portfolios, mitigating margin pressure, strengthening physician alignment, or expanding ambulatory platforms, leadership teams require clear financial modeling, objective valuation insight, and data-driven analysis to make confident decisions in an increasingly complex healthcare environment. These decisions are foundational to long-range community positioning, and proactive board engagement will be required in contemplating an orderly and fiscally responsible migration.
As healthcare moves through this period of evolution, organizational decision-making must be informed by resilient strategy development that is grounded in data and responsive to an ever-changing healthcare environment.
