Fast vs. durable growth: Which increases your valuation more?

Does fast growth always increase your valuation? Learn how buyers assess growth, red flags that reduce multiples, and how to strengthen exit readiness.

There’s a difficult strategy question that I hear a lot from mid-market healthcare CEOs:

“Do we have time to slow down and get better before we get bigger? Or should we keep pushing for fast growth at all costs?”

It’s usually framed as an operational priority question, but it’s also a valuation question. Fast versus slow is the wrong question when it comes to exit readiness and getting premium multiples when you sell. 

Savvy investors and buyers know to inspect the durability of revenue, not just speed. Fast growth can absolutely command a premium, but only when its durability is verifiable.

If there is no proof, if it sounds complicated, or growth is disconnected from controllable levers, it becomes a liability during diligence. 

In our Exit Readiness Framework, durability of growth is one of five valuation signals buyers consistently test in diligence. Let’s unpack why.

The misconception most CEOs have

In operating mode, fast growth feels great. Revenue is up. The board is energized. 

In underwriting mode, growth is interrogated more comprehensively. A PE investment committee isn’t asking, “How impressive is this topline revenue?”

PE firms are asking:

  • How repeatable is it?
  • How exposed is it?
  • How fragile is it under pressure?
  • How much of this sits in the founder’s head?

Strategic acquirers are asking something slightly different:

  • Does this integrate cleanly?
  • Does this add complexity?
  • Does this rely on relationships we don’t have?

Second buyers, especially if the company has already been through one private equity cycle, ask the most pointed question of all:

  • What growth is left?

Fast growth without durability looks like more work and future risk, and buyers price in future work. That’s why the durability of growth is a key signal for exit readiness.

We’ve seen fast growth discounted at exit.

A mid-market healthcare company we worked with had grown quickly through a high-performing partnership channel. Revenue was accelerating. But when diligence began, a PE investment committee started pressing on concentration risk.

One partner accounted for nearly 40 percent of new revenue.

Sales process documentation was thin. Positioning shifted slightly depending on who was selling.

None of this showed up in monthly reporting, but it showed up in underwriting. What felt like impressive growth internally looked like exposure externally. The multiple adjusted accordingly.

Nothing was fraudulent. Nothing was reckless. It just wasn’t durable enough to command a premium.

The skyscraper metaphor

Fast growth is adding floors. Durable growth is reinforcing the foundation.

If you add ten floors to a building with stress fractures in the foundation, the asset becomes risky.

From the street, both buildings look taller. From the inside, only one is safe to buy. Savvy buyers are structural engineers. They can and will inspect the structural integrity of your business.

Decisions that look smart short-term but kill buyability

We’ve seen all of these celebrated in operating meetings:

  • Scaling a single high-performing channel without diversifying risk.
  • Discounting aggressively to accelerate topline growth.
  • Custom-building deals that increase revenue but add operational drag.
  • Launching adjacent service lines that are not aligned with the core narrative.
  • Hiring revenue leaders before tightening positioning.
  • Letting founder relationships remain the primary sales engine.
  • Expanding into new geographies before tightening execution in the primary market.

None are inherently bad. They just require a durability plan. Without one, they introduce fragility and risk that later surface in diligence.

Fast growth versus durable growth

Fast growth increases valuation when:

  • Revenue is diversified.
  • Margins are improving.
  • Systems reduce founder dependency.
  • Positioning is consistent across audiences.
  • Expansion aligns with a clear narrative.

Fast growth decreases valuation when:

  • Revenue concentration is rising.
  • Operational complexity is compounding.
  • Margin erodes as revenue climbs.
  • Sales relies on personality over process.
  • The narrative changes depending on who is speaking.

The difference is structural integrity.

Get better while you get bigger.

At Legacy DNA, we specialize in helping healthcare companies with aligning growth, narrative, systems, and leadership. We make the business easy to understand, underwrite, and transfer.

When leaders slow down to clarify:

  • What truly differentiates them
  • Which growth is compounding versus consumptive
  • Where operational complexity is hiding
  • How durable their advantage really is

They accelerate the right kind of scale. That’s speed with durability. That’s clarity with leverage. That’s impact that shows up in valuation.

So, ultimately, which increases valuation more?

Durability wins. Fast growth can command a premium, but only when durability is verifiable. Strengthen the foundation so you can scale with confidence. Buyers pay premiums for confidence.
