Healthpeak (DOC) — Customer Relationships Under the Microscope

Healthpeak operates and monetizes a simple, high-conviction business: acquire, develop, own and manage healthcare real estate — outpatient medical buildings, life science labs, and senior housing — and collect recurring rental and management cash flows from large healthcare providers, biotech tenants and operators. The company generates revenue principally through long-term leases and property management fees, with occasional one-time items such as lease termination payments; its investment thesis depends on stable, high-occupancy relationships with a concentrated set of large counterparties. For a focused read on counterparties and relationship risk, see our homepage at https://nullexposure.com/.

How Healthpeak makes money is straightforward: rent rolls and externally managed operating income, with value driven by lease term length, tenant mix, and geographic concentration in high-value U.S. markets. That model creates both resilience (predictable cash flows from long leases with enterprise tenants) and exposure (sector concentration and regional risk). Below I unpack the key customer relationships disclosed in the FY2025 filings and related press coverage, followed by what those relationships imply about Healthpeak’s operating constraints and counterparty risk.

What the tenant list tells investors about durability and risk

Healthpeak’s disclosed customers skew large, long-term healthcare operators and specialized biotech tenants, which supports cash-flow durability but concentrates risk by sector and geography. The company emphasizes active property management, passing most operating costs through to tenants in lab and many outpatient leases — a dynamic that preserves net operating income but ties performance to tenant financial health and sector demand. Visit https://nullexposure.com/ for a deeper analysis of these relationship dynamics.

Key business drivers to watch:

Long-term leases with enterprise tenants that lock-in cash flows and drive valuation multiple stability.
High revenue concentration in healthcare delivery and life sciences, which amplifies sector cycles.
Geographic concentration in California (lab) and Florida (senior housing), creating cat-exposure and regulatory sensitivity.

Relationship-by-relationship review (all reported counterparties)

CommonSpirit / CommonSpirit Health
CommonSpirit is identified as one of Healthpeak’s largest tenants and represents a meaningful share of outpatient medical segment revenues; the FY2025 10‑K flags CommonSpirit in the company’s customer concentration disclosure. According to a StockTitan summary of the 2025 filings, CommonSpirit accounted for roughly 6% of outpatient medical segment revenue and about 3% of total revenues for periods ending September 30, 2025, underscoring its status as a large, recurring cash-flow source. (Source: Healthpeak FY2025 10‑K; StockTitan summary of Q3 2025 filing.)

HCA Healthcare Inc (HCA)
HCA is likewise listed in the FY2025 10‑K among the company’s largest tenants for the outpatient medical segment, signaling another enterprise-scale healthcare delivery counterparty that contributes to recurring rent streams. The company’s formal 10‑K tags HCA as a largest-tenant relationship in the outpatient portfolio, reinforcing the concentration among major hospital systems. (Source: Healthpeak FY2025 10‑K.)

Graphite Bio, Inc. (merged with LENZ Therapeutics)
Healthpeak amended a lease with Graphite Bio in October 2023 at a South San Francisco lab building, and that tenant later merged with LENZ Therapeutics in March 2024; subsequent filings and press notes disclose termination fee income tied to the expedited lease expiration — $4 million and $13 million for the three- and nine-month periods ended September 30, 2024, respectively — and the lease was modified to accelerate expiration to December 2024. This sequence illustrates how lab tenants can generate irregular, non-rental cash flows and how biotech M&A activity translates into lease renegotiations.

Janus Living, Inc.
Under a strategic initiative, Healthpeak will contribute a 34-community, 10,422-unit senior housing portfolio to an arrangement with Janus Living, where Healthpeak will serve as external manager and retain substantial majority ownership, signaling a pivot to joint-venture operating structures in the seniors segment while preserving management economics and equity exposure.

What the relationship mix implies about operating posture and constraints

Contracting posture: long-term leases dominate. The company explicitly executed an early lease renewal with CommonSpirit that extended weighted average lease term from July 2027 to December 2035, increased contractual rents to market rates, and raised annual escalations — a clear sign that Healthpeak structures leases for duration and cash-flow visibility. Because this constraint names CommonSpirit directly, it confirms that at least some tenant relationships are deliberately long-dated and core to valuation. (Source: FY2025 10‑K evidence.)
Concentration is strategic and material. Healthpeak concentrates in healthcare real estate by design; the filing warns that a sector downturn would have a material adverse effect on operations. California houses a large share of the lab portfolio (≈69% by gross asset value for lab projects) while Florida holds heavy life-plan community exposure, creating geographically concentrated hazard risk such as earthquakes, wildfires and hurricanes. These are company-level constraints drawn from the FY2025 risk disclosures. (Source: FY2025 10‑K.)
Counterparty profile: large enterprises and public payors. The company works with leading pharmaceutical, biotech and healthcare delivery systems and reports Medicare provided roughly 3% of total revenues for 2025, indicating a mix of private enterprise and government payor exposure at the company level. This produces both credit strength (enterprise tenants) and regulatory sensitivity (Medicare share). (Source: FY2025 10‑K.)
Relationship roles and economics. Healthpeak functions as landlord, manager and occasional seller/buyer of services: it provides property management to encourage renewals, generates rental revenue across tenants, and structures lease contracts that largely pass operating costs to tenants (especially in lab leases). Those company-level signals explain why occupancy and rent per square foot are core performance metrics in the filings. (Source: FY2025 10‑K.)
Maturity and activity. Reported occupancy in the outpatient and lab segments is high (average occupancy figures in the mid-to-high 90s in places), supporting the classification of these relationships as active and revenue-generating rather than nascent or transitional. (Source: FY2025 10‑K.)

Investment implications and near-term monitoring

Healthpeak’s cash flows are predictable because of long leases with enterprise healthcare tenants, but investors must weigh sector concentration and regional hazard exposures. The Graphite Bio lease adjustment shows how biotech tenant consolidation can generate both one-time gains and vacancy risk; the CommonSpirit renewal demonstrates the upside from front‑loading long-term contractual security.

If you are evaluating counterparty risk or sizing an investment position, focus on:

Lease maturity profile and weighted-average lease term by segment.
Tenant credit quality among the largest counterparties (CommonSpirit, HCA).
Geographic concentration metrics (California labs; Florida seniors) against catastrophe and regulatory scenarios.

Bottom line

Healthpeak’s customer relationships are anchored by enterprise healthcare tenants and long-term lease economics, which sustain recurring income but concentrate sector and regional risk. The company’s disclosures show active, high-occupancy relationships with significant tenants (CommonSpirit, HCA), opportunistic lease settlements with biotech tenants (Graphite Bio/LENZ), and strategic JV/management arrangements in senior housing (Janus Living) — together defining a business that is predictable in rent roll but exposed to healthcare-sector cycles and localized hazard risk.
