SPATCO Doubles Down on Tank Testing With Two Midwest Acquisitions

SPATCO Energy Solutions, the environmental services platform backed by Dallas-based private equity firm Kian Capital, has acquired two Midwest tank testing companies in deals that accelerate the firm's geographic expansion and deepen its presence in underground storage tank compliance — a market where regulatory pressure and aging infrastructure are driving consolidation.

The company announced today it's adding Discovery Tank Testing, a Michigan-based firm serving the Great Lakes region, and Tank Wizards, an Indiana operator with a foothold in the Midwest corridor. Financial terms weren't disclosed, but the acquisitions mark SPATCO's latest moves in a deliberate buy-and-build strategy targeting the fragmented environmental services sector.

It's the kind of quiet M&A you'd miss if you weren't watching — small deals in an unsexy market. But the underlying thesis is sharp: thousands of aging underground storage tanks across the U.S. are subject to tightening EPA regulations, creating a compliance burden that small operators can't efficiently navigate alone. SPATCO's play is to consolidate these mom-and-pop testing shops into a regional powerhouse with scale, technology, and the capacity to land enterprise contracts.

Mike Towner, SPATCO's Chief Executive Officer, framed the acquisitions as validation of the platform's operational approach. "These acquisitions further demonstrate our commitment to delivering comprehensive environmental compliance solutions," he said in the announcement. Translation: we're building a one-stop shop for tank owners who'd rather deal with a single vendor than coordinate half a dozen compliance specialists.

Underground storage tanks (USTs) are everywhere — gas stations, industrial facilities, airports, military bases. The EPA estimates there are over 500,000 active UST systems in the U.S., and many were installed in the 1980s and 1990s. That means they're hitting the end of their useful life just as regulatory scrutiny intensifies around leak detection, corrosion monitoring, and environmental contamination.

Tank testing and compliance isn't optional — it's legally mandated. Facilities must conduct regular inspections, maintain leak detection systems, and document everything for state and federal regulators. Miss a deadline or fail an inspection, and you're looking at fines, cleanup costs, or operational shutdowns.

The market for tank testing services is highly localized and heavily fragmented. Most operators are small, regional firms — often family-owned — serving a handful of counties. They lack the technology infrastructure, capital, and compliance expertise to compete for large, multi-site contracts from national convenience store chains, fuel distributors, or industrial clients.

That fragmentation creates an opening for consolidators like SPATCO. By rolling up regional players, the platform can offer national clients a unified service footprint, standardized reporting, predictable pricing, and technology integration — things a one-truck operator in Kalamazoo can't deliver.

Discovery Tank Testing, based in Michigan, specializes in compliance testing, leak detection, and environmental monitoring for USTs. The company serves petroleum retailers, industrial facilities, and government clients across the Great Lakes region. Its customer base is concentrated in Michigan, but it also operates in neighboring states where tank compliance requirements are similarly stringent.

Tank Wizards, headquartered in Indiana, provides tank testing, cathodic protection, and compliance consulting across the Midwest. The firm's niche is working with multi-site operators — think regional gas station chains or industrial logistics companies — that need coordinated testing across dozens of locations.

Together, these acquisitions give SPATCO denser coverage in the Midwest, a region where tank infrastructure is aging rapidly and state-level enforcement is picking up. Indiana and Michigan both have aggressive UST compliance programs, meaning demand for testing services isn't going away — it's accelerating.

SPATCO didn't disclose how many customers or employees it's adding with these deals, but the strategic value is clear: more trucks on the ground, more technicians in the field, and more local relationships in markets where trust and responsiveness matter as much as technical capability.

The table shows how SPATCO is filling in geographic gaps. Before these deals, the company had a stronger presence in the South and Southwest. Discovery and Tank Wizards push it deeper into the Midwest, where it can now credibly pitch national clients on coast-to-coast coverage.

Kian Capital Partners, the Dallas-based middle-market firm behind SPATCO, has a track record of backing industrial services platforms and helping them scale through M&A and operational upgrades. The firm typically targets companies in fragmented sectors where technology adoption is low and where a well-capitalized platform can rapidly gain market share.

Roll-up strategies in environmental services aren't new — but they're notoriously hard to execute well. The graveyard of failed consolidations is littered with platforms that bought too fast, integrated poorly, and couldn't retain customers or technicians post-acquisition.

SPATCO's approach appears more measured. Rather than spraying capital across dozens of acquisitions, the company is selectively targeting firms with complementary geographies, established customer relationships, and technical capabilities that plug into its existing service stack.

The key question is whether SPATCO can retain the local expertise and customer trust that made these companies valuable in the first place. Tank testing is a relationship business — clients stick with a provider because they trust the technician who shows up on-site, not because they love the parent company's brand.

SPATCO's bet is that by offering better technology, more predictable scheduling, and unified reporting, it can deepen those relationships rather than dilute them. But that requires serious investment in systems integration, training, and cultural alignment — not just slapping a new logo on the trucks.

Towner acknowledged this in the press release, emphasizing that both acquired teams will continue operating with their existing leadership. "Discovery Tank Testing and Tank Wizards bring deep operational expertise and long-standing relationships in their respective markets," he said. That's PE-speak for: we're not blowing up what works.

The biggest risk in any buy-and-build strategy is integration execution. Acquired companies often struggle to adapt to new reporting requirements, technology platforms, and operational processes. Technicians leave. Customers defect. Margins compress.

SPATCO will need to move carefully here. Discovery and Tank Wizards likely operate on different billing systems, use different testing equipment, and have different service protocols. Harmonizing those without disrupting day-to-day operations is harder than it looks on a PowerPoint deck.

SPATCO isn't the only player pursuing a consolidation strategy in environmental services. The sector has seen steady M&A activity over the past five years as private equity firms recognize the defensive, recurring-revenue characteristics of compliance-driven businesses.

Competitors include firms like Tankpro, a national tank testing and compliance provider; CSI Inspection, which focuses on petroleum equipment compliance; and regional players backed by other PE sponsors. None of these companies disclose financial performance publicly, but industry sources estimate the U.S. tank testing and compliance market generates over $2 billion annually in service revenue.

The market is growing for two reasons: regulatory enforcement is intensifying, and the installed base of tanks is aging. That's a rare combination — demand driven by both compliance mandates and infrastructure replacement cycles.

For SPATCO, the challenge is moving fast enough to build scale before competitors lock up the best acquisition targets — but not so fast that integration quality suffers. These latest deals suggest the company is leaning toward measured aggression: deliberate geographic expansion, not a scattershot buying spree.

One area where SPATCO could differentiate itself is technology. Most small tank testing firms still operate on paper-based workflows — technicians fill out inspection forms by hand, fax them to the office, and someone manually enters the data into a database. That's slow, error-prone, and hard to scale.

A well-capitalized platform can invest in mobile inspection software, automated reporting, and customer portals that provide real-time compliance dashboards. That's a selling point for large clients who need to track compliance across hundreds of locations — and it's a barrier to entry for smaller competitors who can't afford the upfront investment.

Kian Capital didn't disclose when it initially invested in SPATCO or what its ownership stake looks like, but the firm's typical hold period for platform investments is five to seven years. That suggests SPATCO is likely in the middle innings of its value-creation playbook — still adding scale, but eventually headed toward an exit.

The most likely exit paths are a sale to a larger industrial services company or a secondary buyout to another PE firm. Strategic acquirers in the environmental services space include publicly traded companies like Clean Harbors or private platforms backed by larger sponsors looking to enter adjacent verticals.

Valuation in this market typically hinges on EBITDA multiples in the 6x-8x range for environmental services companies with regional scale and recurring revenue. If SPATCO can demonstrate consistent revenue growth, margin expansion through operational improvements, and a track record of successful integrations, it could command the higher end of that range — or higher if it reaches true national scale.

But that outcome isn't guaranteed. Roll-up strategies live or die on execution. If SPATCO can't integrate acquisitions cleanly, retain customers, and maintain service quality, it's just a collection of subscale businesses held together by a common owner — not a differentiated platform worth a premium valuation.

The Discovery and Tank Wizards acquisitions won't be the last. SPATCO's messaging and Kian's playbook both point toward continued M&A. The question is how fast the platform moves and whether it can maintain operational discipline as it grows.

Key signals to watch include customer retention rates post-acquisition, margin trends, and whether SPATCO starts pursuing larger, more transformational deals or sticks with tuck-ins. The company will also face a decision point around technology investment — whether to build proprietary systems or acquire a software-enabled competitor that's already digitized its workflows.

For now, the broader trend is clear: environmental compliance isn't getting simpler, and the small operators who've dominated this market for decades are aging out. That creates a window for well-capitalized platforms to consolidate, professionalize, and capture share.

SPATCO's challenge is to move through that window before it closes — and before every other PE-backed roll-up in the space has the same idea.

Tank testing isn't sexy. It's not AI, it's not fintech, and it's not going to make headlines outside of industry trade publications. But that's precisely why it's attractive to middle-market private equity.

The business is defensive — demand is driven by regulation, not discretionary spending. It's fragmented — meaning there's room to build scale through acquisition. It's sticky — once a customer establishes a relationship with a testing provider, switching costs are high. And it's capital-light — the main assets are trucks, equipment, and trained technicians, not heavy infrastructure.

Those characteristics make tank testing a textbook buy-and-build candidate. The challenge is execution — turning a collection of acquisitions into a platform that actually creates value beyond the sum of its parts.

SPATCO's latest moves suggest it's on that path. Whether it gets there depends on what happens in the next 12-24 months — and whether the company can integrate what it's bought without breaking what made those businesses work in the first place.
