Key Takeaways

  • American Securities maintains an 80%-plus CEO retention rate across its 30-year history, keeping the incumbent executive from acquisition through exit.
  • The firm built an in-house Resources Group of roughly 50 functional specialists, making it larger than its core investment team.
  • Instead of deploying shadow CEOs or adversarial operating partners, functional experts take on heavy operational lifts like rolling out two enterprise ERP systems per year.
  • Capital is treated as an undifferentiated commodity; operational edge comes from augmenting management rather than threatening executive autonomy.

The Flaw of the Shadow CEO Model

Private equity sponsors often treat portfolio leadership as a variable to replace. The standard playbook installs an operating partner who hovers over the C-suite, monitors operational metrics, and functions as an unelected shadow chief executive. This dynamic creates immediate friction. Incumbent executives spend their days defending territory rather than running the business.

American Securities took the opposite path. Over three decades of middle-market industrial buyouts, the firm built a model where “more than 80% of the CEOs who were there when we invested in the company were there when we exited or are there with us today,” according to co-founder and CEO Michael Fisch.

Keeping leadership intact requires removing the threat of an adversarial sponsor. When private equity firms push generalist operating partners into portfolio companies, they blur accountability. Fisch built an alternative structure that treats the sponsor as specialized support rather than an impending replacement.

In-House Specialists Over Operational Generalists

The engine behind this retention rate is the American Securities Resources Group. It is a dedicated unit of roughly 50 functional specialists covering areas like procurement, executive talent acquisition, and digital infrastructure. Fisch noted that this team has become “the largest sector of our firm for years now, bigger than our investment team.”

The functional focus matters because it targets specific operational bottlenecks without stepping on executive toes. Management teams do not struggle because they lack capability; they struggle because they run lean and lack bandwidth for massive, non-recurring projects.

Fisch framed the dynamic directly: “Because as I tell prospective CEOs, it's not that our any of our people are necessarily better than your people. It's that your people have a day job. And our resource group day job is to help your people win.”

Consider enterprise software overhauls. A typical mid-market company might execute one major software transition per decade, leaving internal teams unprepared for the disruption. By contrast, the American Securities IT unit manages “typically two ERP systems every year because our portfolio is big enough.” The firm brings repeatable, specialized execution to projects that would otherwise derail a portfolio company's core operations.

Treating Capital as a Commodity

In a mature buyout market where capital is widely available, debt structures and financial engineering no longer provide a durable moat. As Fisch put it, “Money is the ultimate commodity. So all private equity firms in a sense are in a commodity business, but we're really in the people business.”

When firms compete on financial terms alone, winning bids often lead to aggressive value-creation plans that overextend existing management. Squeezing margins while imposing top-down operational mandates burns out leadership teams and triggers executive turnover. By offering an infrastructure of shared functional specialists instead of intrusive oversight, sponsors can derisk operational execution without triggering the disruptive churn of an executive search.

Why It Matters

High CEO turnover in private equity often signals misaligned governance rather than deficient executive talent. As middle-market buyout firms face longer hold periods and complex operational mandates, replacing generalist operating partners with deep functional benches changes the sponsor-management dynamic. Firms that remove friction with incumbent leadership preserve institutional knowledge and protect execution speed across multi-year hold cycles.
