Ingersoll Rand's Acquisition of TMIC/Adicomp: Fueling Growth in the Renewable Natural Gas Revolution

The renewable energy transition is no longer a distant promise—it's a roaring market. And Ingersoll Rand (NYSE: IR) is doubling down on its bet to capitalize on one of its fastest-growing segments: renewable natural gas (RNG). The industrial giant's acquisition of Italy-based Termomeccanica Industrial Compressors (TMIC) and its subsidiary Adicomp—announced this summer for €160 million—is a masterstroke of disciplined M&A strategy. Here's why investors should take note.

The Deal's Value: A Low-Double-Digit Starting Line, Mid-Single-Digit Finish Line

The acquisition's financial terms reveal a compelling value proposition. Ingersoll Rand purchased TMIC/Adicomp at an “attractive low-double-digit EV/EBITDA multiple”, a metric that typically ranges between 10x and 19x. But the real magic comes post-synergy, where Ingersoll Rand expects the multiple to drop to the mid-to-high single digits—a stark improvement.

This reduction hinges on synergies: shared supply chains, combined R&D efforts, and cross-selling opportunities. By integrating TMIC's century-old expertise in air and gas compressors with Adicomp's engineered-to-order (ETO) solutions for RNG infrastructure, Ingersoll Rand is creating a vertical integration play in a sector projected to grow from $10 billion to $30 billion by 2030.

Why RNG? And Why Now?

The RNG market is the unsung hero of the energy transition. Unlike solar or wind, RNG can be stored and transported through existing natural gas infrastructure, making it a versatile solution for decarbonizing industries like agriculture, waste management, and transportation. TMIC and Adicomp are already embedded in this ecosystem: Adicomp designs systems to capture biogas from landfills and dairy farms, while TMIC's compressors are critical for RNG processing and distribution.

Ingersoll Rand's Industrial Technologies and Services (IT&S) segment—which already generates billions in revenue—now gains a full-stack RNG platform. This isn't just about bolt-on growth; it's about owning a niche where few competitors can match their end-to-end capabilities.

The “M&A Flywheel” Advantage

Ingersoll Rand's approach to acquisitions is methodical. The TMIC/Adicomp deal follows a template: target family-owned niche players with proprietary tech and sticky customer relationships, then scale them using Ingersoll's global reach and operational muscle. The result? A “flywheel” effect where synergies from past deals (like 2023's Rotaflex acquisition, which boosted ROIC to mid-teens) fund future growth.

The risks? Integration challenges and macroeconomic headwinds are valid concerns. Yet Ingersoll Rand's track record—its 2025 Q1 IT&S segment delivered $389 million in adjusted EBITDA despite margin pressures—suggests it can navigate these hurdles.

Geographic Expansion: A Global Play with Emerging Market Upside

TMIC/Adicomp's footprint in Italy, North America, Brazil, and India isn't just about diversification—it's about tapping high-growth regions. Brazil's booming agribusiness sector and India's push for clean energy subsidies create ripe markets for RNG infrastructure. Ingersoll Rand's existing U.S. and European presence now gains a bridge into these frontiers, reducing reliance on cyclical demand in mature economies.

The Investment Case: A Stock Undervalued by the Market's Shortsightedness

Analysts have already begun pricing in the upside. The median price target for Ingersoll Rand now sits at $100.50, with bullish calls reaching $105—a 15% premium to current levels. Yet the stock remains underappreciated by investors fixated on short-term macro risks.

Consider this: Ingersoll Rand's free cash flow surged 124% year-over-year in Q1 2025 to $223 million, fueled by disciplined capital allocation. With $4.2 billion in liquidity and plans for up to $750 million in buybacks this year, the company is primed to reward shareholders as synergies materialize.

Final Take: Ride the RNG Wave with Ingersoll Rand

This acquisition isn't just about buying a company—it's about buying a strategic moat in a $30 billion market. Ingersoll Rand's combination of low-double-digit entry multiples, post-synergy leverage, and RNG's structural growth makes it a rare blend of value and momentum.

For investors seeking exposure to the energy transition without the volatility of pure-play renewables, Ingersoll Rand offers a safer, diversified bet. The stock's current valuation leaves room for upside as RNG adoption accelerates. This is a long-term story, but with the right execution, it's one that could deliver outsized rewards.

Investment Advice: Add Ingersoll Rand to your watchlist. The RNG tailwinds and disciplined M&A playbook suggest this stock is set to outperform over the next 18–24 months. For aggressive investors, consider a gradual build into the position as synergies become clearer. The RNG revolution isn't just coming—it's here. And Ingersoll Rand is ready to fuel it.
