TENET HEALTHCARE CORP

TENET HEALTHCARE CORP (None, CIK 0000070318) — US-listed company materially exposed to Medical Imaging Systems.

Tenet Healthcare is a U.S. healthcare services company operating in two reportable segments: Hospital Operations and Services and Ambulatory Care. The basic monetization model is fee-for-service and contract-based payment for hospital and surgical care: Tenet is paid by Medicare, Medicaid, commercial insurers, employers, and patients for inpatient admissions, outpatient visits, emergency visits, and surgical procedures.

Using FY2023 reported segment net operating revenues from the 10-K:

Source: [1] Tenet 10-K FY2023, filed 2024-02-16, accessed 2026-04-26. The segment shares are derived directly from the $16,292 million and $4,256 million segment revenues divided by the $20,548 million consolidated total. The calculation is:

• Hospital share: $16,292 / $20,548 = 79.3%
• Ambulatory share: $4,256 / $20,548 = 20.7%

This mix is important for the thesis: Tenet’s fastest-growing and highest-margin strategy is the ambulatory business, but the hospital segment still drives roughly four-fifths of revenue.

Tenet reported Adjusted EBITDA of $3,472 million on $20,548 million of net operating revenues in FY2023 [1]. That is a non-GAAP profitability measure, but it is the company’s principal segment performance metric. The derived Adjusted EBITDA margin is:

\[

\text{Adjusted EBITDA margin} = \frac{3,472}{20,548} = 16.9\%

\]

This calculation is source-bound to [1] and is derived, not a line item quoted as a margin in the filing.

Tenet also reported net income available to common shareholders of $611 million in FY2023 [1]. That implies a net margin of:

\[

\frac{611}{20,548} = 2.97\%

\]

That wide spread between a 16.9% Adjusted EBITDA margin and a 3.0% net margin reflects interest expense, depreciation and amortization, restructuring/impairment charges, and income taxes. I am not quoting a GAAP gross margin here because healthcare provider income statements do not present a traditional “cost of goods sold” line in the same way an industrial company does; the 10-K disaggregates operating costs into salaries, wages and benefits, supplies, other operating expenses, depreciation, and impairment. Any reader wanting reported GAAP operating income should pull the exact Consolidated Statements of Operations line item from the 10-K directly; I am not approximating it here.

Tenet monetizes through:

1. Hospital inpatient and outpatient services — paid on a per-discharge or per-day basis under Medicare’s inpatient prospective payment system, or through negotiated commercial per-diem/case rates.
2. Ambulatory surgery center procedures — paid per procedure under Medicare’s outpatient prospective payment system or negotiated commercial rates.
3. Value-based contracts — upside or downside adjustments tied to quality and cost metrics.

The 10-K describes the company’s revenue recognition as patient service revenue reported net of contractual allowances and discounts, which is standard for hospital operators [1].

For unit economics, I provide a worked market-share/TAM calculation in the “Worked calculation” section below, because exact per-case volume and revenue-per-case data require the 10-K volume table and risk being misquoted if not verified directly. The important economic logic is that hospital revenue is capital- and labor-intensive, while ambulatory surgery carries lower fixed costs per procedure and is typically higher-margin.

The 10-K identifies Medicare and Medicaid as the principal government payors and states that a large share of hospital revenue comes from commercial managed care contracts [1]. I am not quoting an exact payer mix here because the payer-mix percentages from the filing require line-by-line verification from the 10-K’s revenue disclosures and are not reproduced in this note from memory. Mark as: needs primary source validation for exact payer mix percentages.

Top commercial payor names are not individually disclosed in the filing. The 10-K does not identify any single non-government customer as exceeding 10% of revenues; government programs are treated as principal funding sources. This is important: the “buyer” is not one large enterprise customer but a fragmented set of payors and patients.

From the filing, the buyer classes are:

• Medicare fee-for-service beneficiaries
• Medicare Advantage enrollees
• Medicaid beneficiaries
• Commercial insured patients through employer-sponsored or individual plans
• Self-pay/uninsured patients

The payors are not named as commercial “customers” in the filing beyond the government programs. The 10-K’s revenue recognition and business sections describe Medicare, Medicaid, and commercial payors as sources of payment [1]. This means we cannot produce a legitimate named-customer list such as “UnitedHealth,” “Aetna,” or “Cigna” from the filing itself. Any such names would be speculation.

• Medicare — identified in [1] as a principal governmental payer.
• Medicaid — identified in [1] as a principal governmental payer.
• No single non-government customer is identified in [1] as representing 10% or more of revenue.

That last point is important for conviction scoring: Tenet has diversified payors, but it is heavily exposed to government program rates, which are not subject to Tenet’s pricing power.

Tenet Healthcare’s hospital segment is a material buyer of imaging equipment

\[

\text{Tenet share} =

\frac{16,292}{1,500,000}

= 0.01086

= 1.1\%

\]

Tenet’s hospital segment therefore represented about 1.1% of U.S. hospital care expenditures in 2023.

For comparison, HCA Healthcare reported net revenues of $64,968 million in FY2023 [2]. Its comparable U.S. hospital spending share is:

\[

\frac{64,968}{1,500,000} = 0.0433 = 4.3\%

\]

That is a meaningful scale gap: HCA is roughly four times Tenet’s hospital-segment spending share at the national level.

Source for all inputs: [1], [3]. Values are derived from reported FY2023 revenue and CMS national health expenditure data.

This calculation demonstrates that Tenet is not a “national hospital spending share” story; the company’s alpha, if any, comes from its higher-growth ambulatory segment and selected local market depth rather than national hospital market share.
