Turning Horsepower into Recurring Revenue

Today, I'm looking at Archrock (AROC), the largest natural gas compression service provider in the U.S. They keep gas flowing through the midstream system by renting out horsepower on long-term contracts. It's basically “compression-as-a-service.”

Here are a few takeaways from the report:

• ~85% of revenue is recurring from multi-year service contracts.

• Gross margin has climbed from 31% in 2022 to nearly 46% today—process discipline pays.

• Scale matters here: more fleet density, better uptime, more pricing power.

• But...they carry ~$2.6B in net debt, and integration risk is real after multiple acquisitions.

This one is a case study in building a sticky, recurring revenue model even in a heavy-asset business. The downside is that these asset-heavy businesses and their high debt/leverage can make the model fragile if the cycle turns.

That said, this type of recurring revenue in an asset-heavy business is something that's new to me and rather compelling. So this was a fun report.

With that, I'll see you tomorrow.

The N.O.O.B. Nine — Competitive Powers

The Nerd Out on Business Nine is made up of Hamliton Helmer's famous "7 Powers" of competitive advantage (Scale Economies, Network Economies, Counter-Positioning, Switching Costs, Branding, Cornered Resource, and Process Power) combined with two of my own (Data Flywheel and Distribution Advantage).

Average Score: 3/5 - Archrock has a durable moat based on scale, process, and distribution—not unassailable, but solid.

Memorable Marketing

Overall Approach: Archrock markets reliability and safety above all else, selling a “no downtime” promise. Channels include direct sales, trade shows, investor comms, and proof-driven safety programs.

  • Hook: Promote zero-incident mindset.

  • Channels: Training, customer QHSE talks.

  • Why It Worked: Customers value lower operational risk.

  • Result: TRIR of 0.17 in 2024, strong credential for RFPs.

• “Leader in Electric Motor Drive” (2025)

  • Hook: Push eco-friendly compression as EMD expands.

  • Channels: Press releases, IR deck, sales collateral.

  • Why It Worked: Meets customer compliance needs.

  • Result: Strengthened Permian Basin fleet and positioning.

• “Scale Story in M&A” (2019–2025)

  • Hook: Use horsepower additions as proof of scale.

  • Channels: Investor comms, press releases.

  • Why It Worked: Simple metrics (“added 530k HP”) stick.

  • Result: Elite (2019), TOPS (2024), NGCS (2025) all boosted credibility.

Tactical Takeaways for Founders

1. Turn safety or reliability metrics into marketing assets.

2. Share scale milestones in simple, memorable numbers.

3. Align with regulatory tailwinds and package compliance support as a service.

4. Make training hours and certifications part of your brand story.

AI Uses & Opportunities

• Current Use: Likely uses telemetry analytics, but no disclosed large-scale AI systems.

• Future Plays:

  • Predictive maintenance to slash downtime.

  • Dynamic technician dispatching with reinforcement learning.

  • Renewal and pricing scoring based on equipment usage data.

  • Methane monitoring and compliance services as an add-on.

Bumps in the Road

• Cyclical Exposure: Utilization tied to customer capex and gas markets.

• Heavy Leverage: ~$2.6B debt, concentrated maturities in 2027, 2028, 2032.

• Integration Risks: Needs flawless execution to integrate recent acquisitions.

• Environmental Rules: Methane standards may push costs down the chain.

Your Swipe File

• Build recurring service models around critical functions customers cannot DIY.

• Standardize and scale process power to steadily expand margins.

• Sell with simple, proof-based metrics that prospects remember.

• Don’t overextend: growth with too much leverage is fragile.

• Treat safety and compliance as commercial advantages, not just obligations.
