Firefly AB: Invisible but essential infrastructure
Deep-dive
Hi there ,
What if you could detect the precursor to a fire? Let’s say an ember, or a spark. Having a system like that in place could save companies a fortune in lost production time, inventory and repairs.
Well, there’s a small company in Sweden that focuses on solving exactly this issue.
Enter Firefly AB.
The core concept: preventive vs reactive
Firefly specialises in designing, manufacturing and installing advanced fire prevention systems used in environments where there is a high risk of ignition.
Think dust-heavy or high-temperature industrial processes like wood processing, paper, food production or recycling.
A traditional fire suppression system activates when there is already a fire. By the time the sprinklers go off, you have already lost production time, probably damaged equipment and inventory.
Firefly’s systems detect the precursors to a fire: hot particles, sparks or just elevated temperatures. Once identified, the system extinguishes them before ignition, potentially saving companies of damages worth millions of dollars.
Firefly’s business model
The company operates with a systems-led business model (approx. 70% of revenues) complemented by a growing aftermarket segment (30% of revenues).
The core of the business is the sale of engineered fire prevention systems, typically built around the EXIMIO control platform. These systems integrate detection, suppression and control into customer-specific industrial processes.
In addition, Firefly sells components such as flame and gas detectors under the Omniguard brand, although these are closely linked to system deliveries.
The second major revenue stream is the aftermarket, which includes service contracts, spare parts, commissioning and repairs. This segment is strategically important due to its recurring nature.
Firefly also has an infrastructure division (Sentio) covering metro tunnels, rail, road and cable tunnels. But this segment is rather small.
The production model is capital-light. Firefly outsources the majority of manufacturing to suppliers and handles configuration, final assembly and quality control itself.
The moat is in the nose
Firefly AB maintains a strong competitive position by leveraging its technology and deep process knowledge (accumulated over 50 years). A central differentiator is its advanced Multiple Gas Detection (MGD) technology, which utilizes software to function as an “electronic nose”.
Unlike standard detectors, this system identifies specific gas patterns and relationships to detect early fire gases and other emissions, such as methane and propane. This allows for the identification of potential ignition sources before a fire or explosion occurs.
Furthermore, these systems offer superior environmental robustness, as they remain unaffected by harsh industrial conditions like dust, moisture, vibration, or rapid temperature changes that often trigger false alarms or failures in competing products.
The company’s recent launch of Firefly Prediction in the first quarter of 2026 marks a strategic shift from reactive fire protection toward active preventative analysis.
Instead of responding to an existing spark or ember, the system analyses environmental indications to detect dangerous changes at an early stage, with the ultimate goal of preventing costly unplanned production downtime.
Add to that the typical lifespan of a system (15 years), and we can confidently say that the entry barriers are high.
Growth and profitability swings
Revenues and margin development between 2022 and LTM tell an interesting story. Revenues grew at rapid pace until 2023 driven by post-pandemic demand and a successful expansion into Eastern Europe and Italy.
Stagnation followed ever since as conversions decreased. Firefly is very prone to the macro-economic environment. If companies are unsure about major investments, Firefly will be impacted directly. Think war, tariffs or inflation.
“We are seeing that customers tend to delay or postpone investment decisions (orders) during periods of heightened market uncertainty and geopolitical concerns.” - CEO, Firefly AB
Revenues did take a hit in 2024 when the company divested its Italian explosion protection business, shaving off SEK15m.
Gross margins generally remained stable. Yes, there was the divestment I just mentioned which increased margins as it was a low value-add business.
Beyond that, The drivers for Firefly’s changing gross margins between 2021 and Q1 2026 include a mix of strategic structural changes, fluctuations in high-margin service revenue, and the unique way the company classifies its production costs.
The company is profitable, and hovering around the 10% net profit margin. This is not great, especially given that the company is very much influenced by the macro environment. As you can see, for LTM, the margin is actually deteriorating to 8.7%. Even at its peak in 2024, the margin only grew to 11.7%.
Luckily, Firefly runs a tight ship, which is visible when you dive into their balance sheet. No debt, net cash position, no liquidity issues and a very strong equity position.
The company’s financial target is for net cash to exceed 5% of turnover. In Q1 2026, net cash amounted to 19% of the rolling 12-month turnover.
Excess cash will likely be paid out in a dividend. That does raise a concern. Why does the company not reinvest this money? As an investor, I rather see this capital be deployed.
Capital allocation track record
As I mentioned earlier, Firefly runs an asset-light business. This means it outsources the majority of manufacturing to suppliers and handles configuration, final assembly and quality control itself.
CapEx is neglectable, and not a concern for investors. The company does not require significant reinvestments to keep on generating the same level of earnings.
ROA and ROIC remain relatively high. Given that Firefly is debt-free the returns are basically a snapshot of how the company is compounding its earnings.
The returns did top off in 2024, which was a record year. This is currently not a concern, as the company also flagged that the macro environment remains an issue.
Do we feel comfortable with management?
Anders Bergström is the CEO of Firefly AB, since May 2024. He has been with the company since 1990 and previously served as the General Manager for Industrial Applications. He succeeded former CEO Lennart Jansson, who stepped down to join the board of directors.
Bergström has a long history at Firefly, having worked as a service engineer, area sales manager, and sales director. He has established a new management team, including CFO Agneta Thelander, to guide Firefly’s growth.
His strategic direction
The CEO is a man on a mission with a clear vision. First, he restructured the business internally so regions get a bigger weight in shaping things. This in turns helps smoothen operations.
An important initiative was Firefly’s entry into the U.S. in 2025, which marked a shift from exporting systems into the region to establishing a local operating presence through Firefly US LLC.
Strategically, the move is less about immediate system sales and more about building a long-term, service-driven business. By having a local presence, Firefly can offer maintenance, spare parts, and service contracts.
“Establishing operations and hiring personnel is associated with significant costs. To mitigate risk …, we have chosen to scale the expansion gradually and step by step. As we see our investments generating results, we expect to increase the pace going forward.” - CEO, Firefly AB
This is critical given that aftermarket already accounts for roughly 30% of revenue and carries higher margins. The expansion enables a “land-and-expand” model: install systems, grow the installed base, and generate recurring revenue.
In Q1 2026, the company launched Firefly Prediction, an advanced solution that analyses environmental factors to detect dangerous changes before fires or explosions occur. Beyond safety, the long-term goal of this initiative is to prevent unplanned production downtime, adding significant economic value for industrial customers
The CEO also laid out new targets for 2030. These include achieving an average annual sales growth in constant currency exceeding 15% and an overall operating margin exceeding 15%.
As of the end of 2024 and through early 2026, insiders (consisting of the Board of Directors and senior executives) own approximately 40% of the total shares in Firefly.
The company’s ownership is heavily concentrated in its Chairman, though several other members of the management team and board maintain personal stakes.
Risks to consider
The company’s ability to grow, particularly in its high-margin aftermarket segment, is critically dependent on its ability to attract and retain specialized labor.
The shortage of traveling service technicians is repeatedly identified as the company’s "biggest challenge" and a primary limiting factor for growth.
Because the business relies on technical expertise for system commissioning and maintenance, the loss of key individuals or an inability to recruit competent engineers directly impacts operational capacity
Next to that, Firefly is highly sensitive to fluctuations in the global currency markets because of a structural mismatch between its costs and its revenues. A large portion of the Group’s costs are in SEK, while a majority of its invoicing is in foreign currencies like the EUR and USD.
The company's performance is tied to the general investment willingness of its customers, which is sensitive to broader economic cycles.
Valuation
Firefly is an industrial player with an asset light model, dependent on macro economic cycles, with a proprietary product. They also carry no debt.
Given this setup, one can argue that multiple metrics might do justice to properly valuate the company.
Firefly’s 5y avg. PE is 21.8, which is very close to today’s PE of 20. I expect an earnings growth of 11.5%, existing out of EPS growth (8%) and a dividend (3.5%). So far, the valuation seems fair to me.
On a FCF yield basis of 4.8% and a reverse DCF of 10.2%, you also cannot argue that the company is cheap, but neither is it expensive.
Overall, Firefly seems fairly valued. At the moment of course, that valuation might even seem a bit expensive. It is definitely not the most optimal entry point, but then again, I do not try to time the market.
Landing the plane
I expect Firefly to continue to do well. They seem to have identified a key growth driver in recurring revenues, as well as the US market. For both, they are taking the necessary initiatives.
It’s true that their performance correlates to the macro economic environment, so fluctuation in results should be expected going forward. The CEO was very clear:
The decline is primarily driven by a slow economy in the construction market, which impacts our historically largest segments. We have been successful in reallocating resources and shifting our focus toward other industries that are currently performing better.
However, the decline within these core industries was significant during Q1. We do not currently see any signs of a near-term recovery in these segments, but neither do we see indications that market conditions are deteriorating further. Given the unpredictability of the markets, the situation could change quickly in either direction.” - CEO, Firefly AB
At its current valuation and given the near-term outlook, the company appears fairly priced. However, looking past short-term macro noise, it’s clear they’re executing well, advancing the right initiatives across product development, geographic expansion, and a shift toward recurring revenue.
Initiating a tracking position at this stage seems reasonable, particularly considering the company’s quality and the strength of its management team.
