Senior housing carries the lab recovery bet

Healthpeak owns healthcare real estate, mainly outpatient medical buildings, lab space, and senior housing.
Senior Housing was the clear growth engine in Q1 2026, with Same-Store Adjusted NOI up 13.8%.
Lab is the weak spot, with Same-Store Adjusted NOI down 7.2% and same-store occupancy at 90.4%.
Management says lab occupancy should grow by at least 100 basis points versus year-end 2025.
Outpatient Medical remains steady, but Q1 2026 Same-Store Adjusted NOI growth slowed to 2.4%.

01 Running thesis

A split portfolio

Healthpeak is in a tug-of-war. Senior Housing is doing the heavy lifting, with Same-Store Adjusted NOI up 13.8% in Q1 2026. Outpatient Medical is still positive, but slower. Lab is pulling the other way.

The bull case is simple: Senior Housing keeps growing at a strong rate, and the Lab business stops getting worse. Management gave investors a clear test. It expects lab occupancy growth of at least 100 basis points versus year-end 2025.

The bear case is that the lab recovery is more talk than fact. Lab Same-Store Adjusted NOI fell 7.2% in Q1 2026, and same-store occupancy was 90.4%, far below 97.8% a year earlier. If biotech tenants do not sign leases, strong senior housing results may only cover up the drag.

The next few quarters matter. Watch lab occupancy, senior housing growth, and management comments on 2027 lab renewals. Management said 2027 renewal rates should be a lot higher than 2026, but investors still need proof.

May 2026→Q1 2026 made the story more split. Lab Same-Store Adjusted NOI fell 7.2%, but management said lab occupancy should grow by at least 100 basis points versus year-end 2025.

Feb 2026▼The 2025 10-K confirmed a sharp fall in Lab occupancy, from 97.8% to 90.1%. Senior Housing and Outpatient Medical stayed positive, but the Lab drag became harder to ignore.

Oct 2025▼Q3 2025 showed Lab Same-Store Adjusted NOI down 3.2% and Outpatient Medical growth slowing to 2.0%. The thesis became more cautious because weakness spread across larger parts of the portfolio.

Jul 2025→Q2 2025 kept the Outpatient Medical merger story on track, but Lab growth slowed as occupancy slipped. The view shifted from simple merger execution to watching biotech demand.

Apr 2025▲The first post-merger quarter supported the Physicians Realty Trust deal, with Outpatient Medical Same-Store Adjusted NOI up 5.0%. That gave early proof that the larger platform could work.

Feb 2025→The initial thesis framed Healthpeak as a healthcare REIT with Outpatient Medical, Lab, and CCRC real estate. The main debate was whether the Physicians Realty Trust merger would add scale without creating integration problems.

02 Business model

Rent from healthcare buildings

Healthpeak is a REIT, which means it owns real estate and must pay out much of its taxable income to shareholders. It makes money from rent, tenant payments, and resident fees tied to healthcare properties.

Outpatient Medical and Lab properties work mostly like landlord businesses. Tenants lease space, and Healthpeak benefits from renewals, rent increases, and higher occupancy. Senior Housing is different because Healthpeak participates more directly in the operating cash flow through RIDEA structures, where property results depend on resident rates, occupancy, and costs.

The model can work well when demand is steady and financing is available. It can break when tenants lose funding, operators face high labor costs, or interest rates make debt and property values less attractive.

03 Product portfolio

Three engines, one drag

Steady

Outpatient Medical

These are medical office buildings and hospitals, often near hospital campuses. Same-Store Adjusted NOI grew 2.4% in Q1 2026, which is positive but slower than full-year 2025 growth.

Option

Lab

These buildings serve biotech, pharma, and medical device tenants in life science markets. The upside is a leasing rebound, but Q1 2026 showed a 7.2% Same-Store Adjusted NOI decline.

Growth engine

Senior Housing

These communities serve older adults and are tied to resident rates, occupancy, and operating costs. This was the strongest segment in Q1 2026, with Same-Store Adjusted NOI up 13.8%.

Option

Development and redevelopment

Healthpeak can build or improve properties to create future growth. This adds upside, but it also adds risk if construction costs, tenant demand, or interest rates move against the company.

Option

Other investments

The company also has smaller non-reportable investments, including loans, preferred equity, and a few other properties. These are not the main story, but they can add complexity.

05 Risk factors

What could go wrong

Lab recovery misses the target

High impact · Medium odds

Management expects lab occupancy to grow by at least 100 basis points versus year-end 2025. That is now a key part of the bull case. If leasing does not convert, the Q1 2026 decline in Lab Same-Store Adjusted NOI could continue.

We watchLab occupancy versus 90.1% at year-end 2025 and 90.4% at Q1 2026, plus signed leases and commencements.

Biotech funding stays weak

High impact · Medium odds

Lab tenants need capital to fund research, hire people, and lease space. Healthpeak's filing warns that if funding is hard to get or unavailable, tenants could be hurt or fail. That risk has already shown up in lower occupancy.

We watchLife science tenant capital raising, M&A activity, tenant failures, and demand for lab space in San Francisco, San Diego, and Boston.

Senior Housing growth slows

Medium impact · Medium odds

Senior Housing is covering weakness elsewhere. The open question is how much of the growth comes from higher resident rates versus occupancy gains. If rate increases slow or labor costs rise, the segment may not keep growing at a double-digit pace.

We watchSenior Housing Same-Store Adjusted NOI growth, occupancy, resident fee rates, and operating expense growth.

Outpatient Medical loses momentum

Medium impact · Medium odds

Outpatient Medical is the largest adjusted NOI contributor, so even modest changes matter. Q1 2026 Same-Store Adjusted NOI growth was 2.4%, down from 3.8% for full-year 2025. The call did not explain the full reason for the slowdown.

We watchOutpatient Medical Same-Store Adjusted NOI growth, occupancy, lease renewals, and mark-to-market rent spreads.

Rates and capital markets pressure the balance sheet

Medium impact · Medium odds

REITs depend on debt and equity markets to fund deals, refinancings, and development. Higher rates can raise borrowing costs and lower property values. Healthpeak says it uses an investment-grade balance sheet and mostly long-term fixed-rate debt, but the risk is still real.

We watchDebt maturities, credit ratings, refinancing rates, share repurchases, and any change in dividend coverage.

06 Quick answers

In one breath

What does Healthpeak Properties do?

Healthpeak owns and operates healthcare real estate in the United States. Its main areas are outpatient medical buildings, lab properties, and senior housing.

Why is DOC's lab segment important?

Lab was about 36% of Q1 2026 reportable segment Adjusted NOI, so weakness there matters. Same-Store Adjusted NOI fell 7.2% in Q1 2026, and investors are watching whether occupancy recovers.

What is the main bull case for DOC stock?

The bull case is that Senior Housing keeps growing while Lab occupancy starts to recover. Management expects lab occupancy growth of at least 100 basis points versus year-end 2025.

What is the main risk for DOC stock?

The biggest watch item is whether the Lab recovery fails to show up in signed leases and NOI. If biotech funding stays weak, lab tenants may lease less space or struggle to pay.
