Kelso Industries: A Billion-Dollar Business Journey in the MEP Market

Entrepreneurship can be a complex mix of opportunities and challenges, especially in fragmented industries like mechanical, electrical, and plumbing (MEP). The journey of Steve Carroll, a former Walmart employee, is a testament to this. Carroll transformed a failed attempt at passive income into Kelso Industries, a $1.2 billion MEP consolidation platform. Here’s a detailed look at the strategic moves and lessons learned that led to this remarkable success.

Why This Matters

The MEP market is a significant sector, valued at $500 billion, but it's often fragmented, making it challenging for businesses to scale effectively. Carroll’s story highlights how strategic acquisitions and a well-thought-out approach can lead to massive growth in such a fragmented market. This journey underscores the importance of resilience, strategic planning, and the power of leveraging institutional capital.

From Corporate Job to Entrepreneurship

The Initial Spark

While working in a corporate role at Walmart HQ, Carroll observed the fragmented nature of the MEP industry. He wanted to address the coordination challenges between mechanical, electrical, and plumbing contractors. However, starting a construction company from scratch would mean quitting his job and taking massive risks. Instead, he and his childhood friend, Steve Nicholson, who worked in private equity, decided on a smarter and safer path: acquiring an existing business.

The First Acquisition Attempt

Their initial target was a small HVAC business in Fayetteville, Arkansas. They lined up an SBA loan, toured the shop, negotiated terms, and even planned to keep the existing general manager so that Carroll could stay at his Walmart job. However, just days before closing, everything collapsed. The bank backed out, the general manager quit, costs surged, and sales fell. This failure taught Carroll a crucial lesson: go big or go home.

Going Big

Two months after the failed attempt, Carroll found a commercial HVAC company in Phoenix doing $17 million in revenue. The SBA loan couldn’t cover the entire acquisition since the business needed millions in working capital. Carroll and Nicholson built a detailed plan outlining how they'd grow the business post-acquisition and approached Peterson Partners, who agreed to provide the necessary capital immediately. They closed the deal, and Carroll quit his corporate job to focus on stabilizing the business, working 100-hour weeks for the next year.

The Strategic Pivot

The Breakthrough Strategy

The breakthrough came when Carroll and Nicholson pivoted from small passive investments to institutional-backed platform building. They realized that the fastest and safest way to build something massive wasn’t starting from zero but buying established businesses. They acquired over 30 businesses, operating in over 30 states and generating over a billion dollars in annual revenue. Their strategy was simple yet effective: acquire established cash-flowing commercial HVAC companies, keep great operators in place, and roll them into equity partners. This decentralized approach preserved entrepreneurial energy while capturing economies of scale through shared services, technology implementation, and cross-selling opportunities across the portfolio.

The Kelso Industries Model

Kelso Industries' acquisition model centers on partnership rather than integration. Sellers roll 20-40% equity while maintaining operational autonomy. This approach ensures that the entrepreneurial spirit remains intact while benefiting from the centralized support system. Today, Kelso Industries operates nationally with 3,000 customers and thousands of employees, demonstrating the power of consolidation in fragmented blue-collar industries.

Practical Tips

Leveraging Institutional Capital

One of the key lessons from Carroll’s journey is the importance of leveraging institutional capital. Institutional investors like Peterson Partners can provide the necessary funding to scale quickly, which is crucial in a competitive market. Building a detailed plan outlining how you'll grow the business post-acquisition can attract such investors.

Go Big or Go Home

Carroll’s experience highlights the importance of thinking big. After the initial failure, he didn’t settle for a smaller, safer bet. Instead, he aimed for a larger, more impactful acquisition. This mindset helped him build a massive business in a relatively short period.

Maintaining Entrepreneurial Spirit

Kelso Industries’ success is also attributable to its decentralized approach, which preserves the entrepreneurial spirit of the acquired businesses. By rolling sellers into equity partners and maintaining operational autonomy, Carroll ensured that the businesses continued to thrive under their new ownership.

Strategic Acquisitions

Kelso Industries' strategy of acquiring established, cash-flowing companies and centralizing capital, strategy, and support has proven effective. This approach allows for rapid scaling and economies of scale while minimizing the risks associated with starting a business from scratch.

Important Takeaways

  • Resilience and Adaptability: Carroll’s journey showcases the importance of resilience and adaptability. After an initial failure, he didn’t give up but instead learned from his mistakes and pivoted his strategy.
  • Leveraging Institutional Capital: Investing in institutional-backed platform building can provide the necessary funding to scale quickly and effectively.

Conclusion
