Have you heard of tracker equity in DSOs? Here’s how it works.

If you're building or scaling a DSO (dental support organization), you may be weighing how to bring partner doctors into ownership. One approach you might consider is the sub-DSO model, which we explain in this article. 

There’s also a new alternative, tracker equity, that’s gaining traction in the industry. Why? Because tracker equity gives you a way to bring on partner doctors with the same practice-level profit sharing, without having to form and maintain a separate legal entity for every deal. 

Whether you're a DSO leader designing your partnership program or a dentist evaluating what a partnership offer actually gives you, it's worth understanding how it works. In this article, we break it down.

What Is a Sub-DSO?

A sub-DSO is a separate entity created underneath a larger DSO, built around a specific practice or partner doctor. When a doctor becomes a partner under this model, the DSO forms a new subsidiary company just for that doctor's practice. The doctor holds a minority ownership stake in that subsidiary and shares in its profits, while the parent DSO typically holds the majority stake and provides management and administrative support.

If this sounds familiar, it should. It's the same structure we described as the JV (Joint Venture) model in our overview of DSO deal structures: the DSO acquires 51-80% of the practice, the dentist retains 20-49% at the practice level, and the practice pays the DSO a management fee. "Sub-DSO" is industry shorthand for that same joint venture arrangement.

This structure aligns the doctor's incentives with their own practice's performance, since their ownership stake and profit share are tied specifically to how that practice does. It's a proven model, and it works well for a DSO bringing on doctor-partners at the individual practice level.

This model can become more complicated at scale, however. Every new sub-DSO means a new tax ID, a new operating agreement, a new set of state and local filings and licenses, its own bank accounts, and its own service agreement. Multiply that by every partner doctor you bring on and the costs and complexity can quickly add up.

What Is Tracker Equity?

Tracker equity replicates the economics of a sub-DSO without creating a new legal entity for every partnership deal. Instead of standing up a separate subsidiary, the existing DSO amends its operating agreement to authorize a new class of equity units. Each class is tied, or "tracked," to the performance of a specific practice, specialty, or business line within the larger organization.

In our deal structures overview, we also described a HoldCo Equity model, where the DSO acquires 100% of the practice and the doctor rolls part of the purchase price into equity at the holding company level. That structure ties the doctor's upside to the whole platform, not to their own practice's numbers. Tracker equity borrows the single-entity infrastructure of a HoldCo, one parent company, one cap table, but keeps the practice-level tie that defines a JV. Put simply, tracker equity takes the economics of a JV and builds it on the infrastructure of a HoldCo.

Once that framework is in place, bringing a new partner doctor into ownership no longer requires forming a new company. It becomes a matter of granting units in a new tracking class, often through a single agreement rather than a full suite of formation documents.

How Tracker Equity Works in a DSO

One Entity, Multiple Tracking Classes

Under tracker equity, there's still only one legal entity: the DSO itself. What changes is the cap table. Rather than each partner doctor owning shares in their own practice location, they own a class of units within the parent DSO that's defined by reference to their practice's performance.

This means you keep a single tax ID, a single set of state filings, and a single banking relationship, even as you add new partner doctors and new tracking classes over time. The administrative burden that used to scale with every new location instead stays largely fixed.

Tying Value to Performance

Each tracking class is built around a formula, usually based on the specific practice's earnings or a defined performance metric. As that practice grows, the value of the units tied to it grows too. The partner doctor's financial outcome is tied to the results they're actually generating, the same incentive alignment a sub-DSO was designed to create, though it takes far less legal scaffolding to set up.

How the Units Are Granted

Tracker equity is sometimes described as being as simple to grant as a profits interest, and in many cases the units are documented that way. We've written about equity structures dental practices use to bring on partners, including phantom equity, a profit-sharing right that's explicitly synthetic and doesn't include actual ownership. A tracker equity unit works differently: even when structured as a profits interest for tax purposes, it's typically an actual class of units in the parent entity, not a synthetic stand-in for one.

That said, whether a doctor buys into a tracking class, is gifted one, or receives one as a profits interest, the same considerations we've outlined before still apply: vesting schedules, cliffs, repurchase rights at fair market value, and drag-along and tag-along provisions all need to be built into the agreement governing that tracker class. What tracker equity changes is where the equity sits and how much infrastructure it takes to create it, not the partnership mechanics that make the arrangement work.

Why It Might Make Sense for You

If you're a DSO evaluating your partnership structure, tracker equity offers a few practical advantages over standing up a new sub-DSO for every deal:

• Faster closings. Granting units in an existing tracking framework takes far less time than forming and documenting a new sub-entity.

• Lower ongoing costs. You avoid duplicating tax filings, bank accounts, and governance documents for every new partner.

• Cleaner diligence. A single entity with multiple tracking classes is much easier for lenders and future investors to evaluate than dozens of subsidiaries with separate K-1s and operating agreements.

• More flexibility. Tracking classes don't have to be tied to a single location. They can be built around a specialty, a business line, or another unit of your organization, which gives you more options as your structure evolves.

  
  

If you're a dentist being offered partnership, understanding whether you're being brought in through a sub-DSO or a tracking class matters for how your ownership works day to day, including how your interest is valued, how distributions are calculated, and what happens if you or the DSO part ways.

What to Think Through Before You Commit

Tracker equity isn't a universal fix, and it isn't right for every organization or every deal. A few things worth discussing with counsel before you move forward:

• Governance is usually more limited. Tracking units typically carry economic rights tied to the formula, not the same governance protections a minority owner might negotiate in a standalone subsidiary.

• The tracking formula has to be drafted carefully. How performance is measured, how units are valued at exit or departure, and how disputes are resolved all need to be spelled out clearly in the operating agreement.

• Scale should impact your decision. If you're only bringing on a handful of partner doctors, the infrastructure needed to set up a tracking framework may not be worth it yet. This tends to make the most sense once you're managing partnership across many locations.
