What SunTx Capital Partners buys

SunTx Capital Partners is a Dallas private equity firm that backs manufacturing, distribution and service companies, with a clear preference for the Sunbelt. Its stated range is $30 million to $250 million or more of revenue, $5 million to $20 million or more of EBITDA, and $20 million to $200 million or more of enterprise value, and it says it will look outside those limits for a strong team. Its deals include buyouts, management buyouts, growth equity, recapitalizations, family transitions and consolidations.

Its best known work is building roll-ups and taking them public. It formed Construction Partners, the Alabama road builder now on Nasdaq, and backed the ready-mix platform Suncrete, which listed in April 2026 through a merger with a blank check company. Its other active holdings are Interface Systems (managed network and security services), Epoch Solutions Group (utility field software) and Anchor Partners (metal fabrication). A smaller paving, asphalt or concrete company is most likely to meet this group as an add-on to Construction Partners or Suncrete.

Greymont’s take

How SunTx Capital Partners fits a seller

SunTx suits the owner of a Sunbelt manufacturing, distribution or industrial service business with $5 million or more of EBITDA who wants a partner with operating experience and a plan to grow through acquisitions. For paving, asphalt and ready-mix owners, the likelier buyer is a company SunTx built. Construction Partners has announced a steady run of deals, and Suncrete has been buying in Texas, Louisiana and Arkansas. At Hope Concrete, the Foley family kept equity and stayed on to lead operations.

Both of those buyers are public now, so decisions sit with their own boards and managers. Owners should ask who runs the acquisition, whether the price is cash or stock, and what limits apply to selling any shares. For a direct SunTx deal, ask about the hold period: Interface dates from SunTx's first fund.

Questions owners ask

Mostly through companies it built. Suncrete bought Hope Concrete and Nelson Bros. Ready Mix in 2026, and Construction Partners bought paving and asphalt businesses in Florida, Texas, Oklahoma and Tennessee in 2026.

What size company does SunTx look for?

Its parameters are $30 million to $250 million or more of revenue, $5 million to $20 million or more of EBITDA, and $20 million to $200 million or more of enterprise value. It says it will consider strong teams outside these ranges.

Does SunTx own an IT or managed services business?

Yes. Its portfolio lists Interface Security Systems, now called Interface Systems, as active. The St. Louis company provides managed network, voice and security services to restaurants, retailers and other commercial customers.
