Permanent Capital and the Case Against Flipping Operating Companies

Private equity buys to sell. Operating capital buys to hold. The two produce different businesses.

By the Office of the Group · Rothenbury

The dominant ownership model for mid-market operating companies in the past two decades has been private equity: 4-6 year hold, leverage up, optimize for exit multiple, sell to a strategic or to another sponsor. The model is well-understood, well-funded, and produces measurable returns inside a fund cycle. It also produces a specific kind of operating business, one optimized for sale.

A permanent-capital owner buys the same kind of business and runs it differently. The differences are not philosophical. They are observable in the P&L, the balance sheet, and the management roster.

1. Capex profile diverges by year three. Bain's 2024 Global Private Equity Report showed median capex as a percentage of revenue declining 28% in years 4-6 of PE holds versus years 1-3, as sponsors prepare assets for sale and avoid spending that does not translate to immediate EBITDA. Permanent-capital owners run a flat or rising capex profile because the asset has to keep working past year 6.

2. Management retention diverges sharply. PitchBook's 2024 sponsor data showed median CEO tenure inside PE-owned operating companies at 3.4 years, with replacement rates spiking near transaction events. Permanent-capital portfolios show median operator tenure of 8-12 years. The mechanism is straightforward: PE needs a CEO who can sell a story to the next buyer. Permanent capital needs a CEO who can run the business past the cycle.

3. R&D and process investment carry forward. Operating improvements that pay back in 5-8 years (training infrastructure, quality systems, technology platforms, brand investment) show up disproportionately in permanent-capital portfolios because the holder will benefit from them. PE-owned businesses defer the same investments because the next owner captures the return. The Boston Consulting Group's 2024 industrial operations benchmark put process investment as a percentage of revenue at 2.1% for sponsor-owned versus 3.4% for permanent-capital-owned mid-market industrials.

From the Office of the Group

The pushback on permanent capital is usually that it lacks discipline: without an exit clock, what forces operating improvement? The answer is the only thing that ever forced it in any model, capital allocation choices made against alternatives. A permanent-capital owner who is bad at allocation underperforms public market beta. The discipline is real, just measured differently.

The argument is not that permanent capital is universally superior. Some businesses, technology, certain consumer brands, financial services, are well-suited to a transactional ownership cycle. Property services, industrial services, regulated operating companies, and infrastructure-adjacent businesses are not. The decade-plus operating learning curve cannot be reset every five years without leaving most of the value on the floor.

We build to hold because the underlying assets reward it. The capital structure follows.
