8,500 subscribers. Substack bestseller. Hundreds of paying subscribers.
Six months ago, I was writing into the void. Today, we have one of the fastest-growing investment publications on Substack.
I don't take that lightly.
To say thank you, I'm pulling back the curtain on something usually reserved for paid subscribers only.
Last month, I wrote about what I thought was a classic 100-bagger setup - high returns on capital, owner-operator management, massive reinvestment runway.
Since then? Up 50%.
One of the catalysts I mentioned - the uplisting - played out exactly as expected.
Here's the thing: I rarely do this.
Paid subscribers get these ideas first for a reason. They're the ones who make this whole operation possible.
But every once in a while, it's worth showing what happens behind the paywall.
This is the kind of deep-dive analysis paid subscribers see multiple times each month.
Fair warning: This analysis hasn't been updated since the original post. The stock's already moved.
Still valuable?
Absolutely.
It shows the framework. The process. How to spot these opportunities before they become obvious.
Our next potential multibagger idea drops next Friday.
That one's for paid subscribers only.
If you like what we do and how we think, you can consider becoming a paid subscriber here if you want:
No worries if not, I hope you enjoy the todays free post anyway.
95% customer retention rate.
50% operating leverage on incremental revenue.
Zero debt, growing cash pile.
The CEO owns 21% of the business.
The board owns another 14%.
This isn't some speculative growth story.
It's a 25-year-old business that's been profitable for decades, serving customers who literally can't afford to switch.
But here's what changed everything: they just landed a $5 million contract with one of the nation's largest cell phone providers. That's more than half their previous annual revenue. In one deal.
The stock trades at roughly 6x earnings.
The business generates 70%+ gross margins.
And management just announced plans to uplist to NASDAQ.
Most importantly, this fits the 100-bagger framework perfectly:
Quality: Dominant market position with sticky customers who pay annually for 25+ years
Growth: Secular tailwinds from aging grid infrastructure and extreme weather
Management: Owner-operators with serious skin in the game
Price: Reasonable valuation for a asset-light, recurring revenue business
The market is treating this like a struggling small-cap.
But the fundamentals tell a different story.
We personally think this is exactly the type of compounding machine that could turn into a multibagger.
The Company
Acorn Energy (OTCQB: ACFN)
The company is Acorn Energy, which operates primarily through its 99%-owned subsidiary OmniMetrix.
Think of OmniMetrix as the "operating system" for backup generators.
When hospitals, cell towers, data centres, and other critical facilities install backup generators, they need monitoring systems to ensure those generators will actually work when the power goes out.
That's where OmniMetrix comes in.
Their hardware and software monitors generators 24/7, tracking everything from fuel levels to battery status to runtime performance.
More importantly, it can remotely start generators and send alerts when maintenance is needed.
But here's what makes this special: once installed, these systems become virtually impossible to remove.
The Beautiful Business Model
OmniMetrix has built what one industry expert called a "walled garden" operating system.
Once a customer installs their monitoring infrastructure, future installations must be compatible with the existing system.
This creates enormous switching costs.
Imagine you're managing 100 generator sites across multiple states.
Your staff is trained on OmniMetrix's software.
Your maintenance protocols are built around their alerts.
Your reporting systems feed into their dashboard.
Now imagine a competitor offers to save you 20% on monitoring fees. Are you really going to:
Retrain your entire staff?
Rebuild all your protocols?
Risk downtime during the transition?
Potentially compromise the reliability of life-critical backup power?
Of course not.
This is why OmniMetrix maintains a 95% customer retention rate.
This is a textbook example of what Chris Mayer calls a "coffee can" stock - the kind of business you can buy and hold for decades.
Here's why the economics are so attractive:
Recurring Revenue: Customers pay annual monitoring fees that average around $120 per generator. Once installed, the renewal rate is 95%. Think about it - if you're a hospital administrator, are you really going to switch monitoring providers to save a few bucks on something that could mean life or death?
Operating Leverage: Management has demonstrated that roughly 50% of incremental revenue drops straight to the operating income line. As the business scales, profits grow much faster than revenue.
Asset-Light Model: The business requires minimal capital expenditure. Most of the "assets" are the relationships with customers and the proprietary software.
Secular Tailwinds: Aging electrical grid, more frequent severe weather, growing data center demand, and increasing regulations around backup power all drive demand for their services.
The Competitive Moat
OmniMetrix competes primarily against two types of players:
OEM Solutions: Generator manufacturers (Generac, Kohler, Cummins) offer their own monitoring, but these systems typically only work with their specific brand and offer limited capabilities.
Independent Competitors: Small regional players that lack the scale, technology, and cybersecurity capabilities that large enterprises require.
OmniMetrix's competitive advantages are significant:
Brand Agnostic: Their systems work with any generator manufacturer, making them the natural choice for facilities with mixed fleets.
Superior Technology: 25+ years of R&D focused exclusively on monitoring. While generator manufacturers treat monitoring as an afterthought, it's OmniMetrix's entire business.
Scale Advantages: Roughly 30 employees vs. competitors with 5-15 employees. This translates to better customer service, faster innovation, and stronger cybersecurity.
Industry Relationships: Founder Harold Jarrett has been teaching industry courses through the Electrical Generating Systems Association (EGSA) for decades. This creates deep relationships throughout the ecosystem.
Cybersecurity Leadership: Recent investments in cybersecurity capabilities helped them win the major cell phone provider contract. As cyber threats increase, this becomes a bigger competitive advantage.
The $5 Million Game-Changer
In June 2024, OmniMetrix won their largest contract ever - approximately $5 million from a major cell phone provider to monitor backup generators at 5,000-10,000 cell tower sites.
This wasn't just a lucky break.
It was a competitive bidding process against multiple providers. OmniMetrix won because of their superior technology, cybersecurity capabilities, and track record.
The contract breakdown is roughly $4 million in hardware revenue (recognized upon shipment) and $1 million in recurring monitoring revenue.
But here's the key: that $1 million becomes $1 million annually for as long as the customer keeps the service.
Given the 95% retention rate, this single contract essentially added $1 million per year to the recurring revenue base.
But the strategic implications go far beyond the financials:
Validation: Winning against established competitors in a rigorous RFP process validates OmniMetrix's technological leadership.
Reference Customer: Success with this deployment creates a powerful case study for other large enterprise customers.
Scale Demonstration: Managing 5,000-10,000 remote sites proves the platform can handle enterprise-scale deployments.
Revenue Step-Function: This single contract increased the recurring revenue base by roughly 25%.
Management expects to complete hardware shipments in 2025, with monitoring revenue extending well into the future.
Management with Skin in the Game
CEO Jan Loeb owns 21% of the company - roughly $7 million at current prices.
He's been with the company for years and takes a modest $325,000 annual salary with no stock options.
The four-person board collectively owns 14% of the company, mostly purchased with their own money. Total director fees for all four directors is less than $100,000.
This is the kind of alignment you want to see.
When management owns this much stock, they think like business owners, not hired guns.
Secular Tailwinds
Multiple macro trends create sustained demand for backup power monitoring:
Grid Reliability Crisis: The North American Electric Reliability Corporation (NERC) warns that grid reliability risks are "particularly acute" across roughly half the U.S. Aging infrastructure, growing demand, and intermittent renewable sources create increasing outage risk.
Extreme Weather: Climate change drives more frequent and severe weather events. Hurricane Helene alone left millions without power for weeks. Each major event increases awareness of backup power needs.
Data Center Explosion: AI and cloud computing drive exponential growth in data center construction. Every data center needs comprehensive backup power with monitoring.
Regulatory Changes: New regulations require better backup power reliability in healthcare, telecommunications, and other critical sectors.
Corporate Resilience: Businesses increasingly view backup power as essential infrastructure, not optional insurance.
These aren't temporary trends - they're structural shifts that will drive demand for decades.
The Risks
Every 100-bagger candidate has risks:
Key employee departure (especially Harold Jarrett)
Economic downturn reducing capex spending
Dependence on key customer relationships
Technology disruption
Increased competition from well-funded entrants
Small size limiting institutional interest
OTC liquidity constraints
Why Now?
Several catalysts could drive revaluation:
NASDAQ Uplisting: Management announced plans to uplist in 2025, which should increase visibility and institutional interest.
Recurring Revenue Recognition: As more investors understand the sticky nature of the revenue base, the stock should trade at a premium to cyclical small-caps.
Acquisition Strategy: Management is actively seeking complementary acquisitions that could accelerate growth.
Contract Extensions: Success with the cell phone provider could lead to additional contracts with that customer or similar large enterprises.
The Bottom Line
I personally believe OmniMetrix fits Chris Mayer's 100-bagger framework almost perfectly.
It's a quality business with a dominant market position, recurring revenue, strong management alignment, and secular growth tailwinds.
The recent contract win demonstrates the company's competitive strength and provides a foundation for sustained growth.
At current valuations, in my opinion the market isn't pricing in the full value of the recurring revenue stream or the long-term compounding potential.
