The Growth-Multiple Alignment Rule connects the price paid for a company to the rate at which its EBITDA or cash flow can sustainably grow. Begin with the company’s return on invested capital and the structural economics of its industry, then estimate a defensible growth rate using market conditions, competitive position, and operating evidence. Compare that rate with the proposed acquisition multiple. A high multiple can be rational when supported by similarly strong and durable growth, but it becomes dangerous when the multiple substantially exceeds the growth rate. The rule therefore turns valuation into an operating-performance test rather than a comparison with whatever other buyers currently pay.
Origin
Extracted from Masters in Business during Scott Sperling’s explanation of how THL evaluates acquisition valuations in expensive markets.
Core principles
- 01Anchor valuation in sustainable growth rather than market enthusiasm
- 02Treat return on invested capital as a core indicator of intrinsic value
- 03Demand stronger growth when paying a higher acquisition multiple
- 04Model cash flow and EBITDA rather than relying on narrative alone
- 05Avoid valuations that require unrealistic operating performance
How to run it
- 1
Assess economic quality
Evaluate the company’s return on invested capital and the broader economics of its industry. Determine whether the business creates value efficiently before considering its headline growth.
Pro tip Normalize results across a full operating cycle where possible.
Watch out Recent performance may exaggerate economic quality if it reflects temporary conditions.
- 2
Estimate sustainable growth
Project the defensible long-term growth of EBITDA or cash flow using market demand, competitive position, and operating capacity. Separate durable drivers from temporary acceleration.
Pro tip Give the most weight to drivers that can persist without heroic assumptions.
Watch out Do not substitute historical growth for sustainable future growth.
- 3
Calculate the acquisition multiple
Express the proposed purchase price as a multiple of normalized EBITDA or cash flow. Adjust the denominator for one-time gains, losses, and unusual conditions.
Pro tip Calculate the multiple under both base and downside earnings assumptions.
Watch out An inflated earnings denominator can make an expensive transaction appear reasonable.
- 4
Compare price with growth
Check whether the acquisition multiple is broadly supported by the sustainable growth rate. Require stronger evidence as the gap between the multiple and growth widens.
Pro tip Use the transcript’s 15-times and roughly 15-percent example as an intuitive reference, not a universal formula.
Watch out A matching number alone does not prove value if growth is fragile or capital intensive.
- 5
Model the first three years
Build detailed projections for the first three years and test them across different market conditions. Confirm that the company can produce the growth required to justify the entry price.
Pro tip Focus diligence on the assumptions with the greatest effect on cash flow.
Watch out Precision beyond the available evidence can create false confidence.
- 6
Reject unsupported valuations
Walk away when the multiple materially exceeds defensible growth without a credible value-creation bridge. Preserve underwriting discipline even when capital and competition are abundant.
Pro tip Write down the rejection threshold before negotiations intensify.
Watch out Competitive auctions can pressure teams into changing assumptions to justify the price.
In the wild
An investment team considers paying 15 times EBITDA for a company. Its diligence supports sustainable EBITDA or cash-flow growth of about 15 percent, backed by durable demand and a strong competitive position. The team may accept the high absolute multiple because the operating growth falls in a comparable range.
→ The valuation passes the initial alignment test and proceeds to detailed underwriting.
Another business is offered at 15 times EBITDA, but its sustainable growth is only five to seven percent. Even if comparable transactions trade at similar prices, the expected operating performance does not support the acquisition multiple.
→ The team rejects the deal or demands a substantially lower price.
Common mistakes
Using market multiples as the answer
Comparable prices show what others have paid, not whether the company’s cash-flow growth can justify the proposed valuation.
Treating temporary growth as sustainable
A short demand spike can produce an attractive forecast while concealing a much weaker normalized growth rate.
Forcing projections to fit the price
Teams can unconsciously raise growth assumptions after becoming attached to a transaction. Underwriting should determine the price, not rationalize it.
Is it for you?
Best for
It is best for private-equity, growth-equity, and acquisition teams evaluating established businesses with usable operating data.
Not ideal for
It is not ideal for pre-revenue ventures whose future economics cannot yet be estimated with meaningful precision.
From the transcript
“So we're very focused on buying companies where the acquisition multiple is reflective of what we believe to be the sustainable growth rates of that…”
“What you don't want to do is pay fifteen times for something growing five or seven percent.”
“we spend an enormous amount of time trying to model out, particularly the first three years of growth of of a given company”
