Digi International Buys Disruptive Technologies for $130 Million: 250,000 Coin-Cell Sensors and a First Footing in Europe

Introduction

A Minnesota connectivity company and a Norwegian sensor specialist have agreed to merge, and the price tag tells you how seriously the enterprise IoT market has started treating the boring end of the stack. Digi International, the Hopkins, Minnesota-based maker of industrial routers, gateways and embedded modules listed on Nasdaq under DGII, has signed a definitive agreement to acquire Disruptive Technologies for $130 million in cash. The target, founded in Oslo in 2013 and led by chief executive Erik Fossum Færevaag, is a sensing company with more than 250,000 sensors already sitting in real buildings.

What makes the deal more than a line-item acquisition is the mismatch between those two numbers. A hundred and thirty million dollars is a serious multiple against a business that Digi disclosed generated $15 million in calendar 2025 revenue and $4 million in annualized recurring revenue. Buyers routinely pay multiples like that for installed base, and installed base is exactly what Digi is buying: a quarter-million deployed endpoints, a hardware design that runs on a coin cell for up to 15 years, and — the part that cannot be shipped overnight — a set of country-by-country commercial relationships across more than 25 countries.

For readers tracking the Internet of Things category more broadly, this is a useful case study in how the value layer is shifting away from connectivity hardware and toward the platforms, analytics and subscription relationships that sit on top of deployed sensors.

A sensor that is designed around not being touched

Digi chief executive Ron Konezny, speaking on the October 1 conference call that accompanied the announcement, emphasized that Disruptive Technologies does not rely on off-the-shelf components. According to his account, the company has designed its own application-specific integrated circuit and its own wireless protocol, with the explicit goal of low-power operation and small form factor.

That design philosophy is the acquisition's real asset. The sensors are smaller than a postage stamp, are said to tolerate a wider range of monitoring conditions than competing products, and are specified to operate for up to 15 years. For facility operators, that number is the entire commercial argument. A wireless temperature, occupancy or carbon-dioxide sensor that has to be opened up and re-batteried every other year is not a sensor, it is a recurring maintenance line item — one that also requires someone to find the sensor, which in a ceiling void or a sealed wall cavity is often the most expensive part of the job.

Eliminating the battery-replacement cycle changes the deployment economics. It also changes the deployment physics: if a sensor can be glued inside a wall cavity rather than surface-mounted where it can be serviced, integrators can put monitoring in places that were previously uneconomic to reach. The infrastructure required to support a large fleet shrinks correspondingly, because fewer endpoints need a gateway in sight or a field technician in range.

The business model Digi intends to change

The acquisition is also a deliberate reversal of how the target currently sells. Digi plans to fold Disruptive Technologies into its SmartSense unit and to convert a model built on one-time sensor sales plus separate software subscriptions into SmartSense's bundled sensor-and-software subscription.

That conversion is where the reported financial benefit comes from. Chief financial officer Jamie Loch said Disruptive Technologies produced $15 million of revenue in 2025, but only $4 million of that was annualized recurring revenue — meaning the bulk of the business was still hardware transactions. Loch said Digi expects roughly $9 million of incremental adjusted EBITDA and free cash flow in fiscal 2028, and he was candid that the benefit probably scales "a little bit more to the cost side," citing economies of scale in research and development, manufacturing and go-to-market. He declined to give detailed fiscal 2027 earnings guidance but said the deal would be accretive to earnings per share. The deal is funded through Digi's existing revolving credit facility, and against the fiscal 2026 guidance issued August 5, Loch said the transaction would add less than one turn of leverage to gross outstanding debt.

For context on how this business is normally valued, our coverage of IoT hardware consolidation shows a market in which connectivity vendors keep buying rather than building — the pattern is not unique to Digi, but the size of the installed base being bought is what distinguishes this deal.

Three growth lanes, and one new market

Konezny framed the combination as three distinct avenues for growth. The first is expanding faster together in North America, where Digi already has its largest footprint. The second is extending SmartSense into Europe using Disruptive Technologies' existing country-by-country relationships. The third is entering building automation and occupancy markets through additional sensor types, including motion, tactile and carbon-dioxide sensors.

That third lane is the strategically interesting one, and it is also the one where the acquired customer base is least directly transferable. Disruptive Technologies' deployments are concentrated in traditional office environments and, to a lesser extent, manufacturing — Konezny said so plainly on the call. Building automation is a different buyer with different certification requirements, different integrators and a much longer qualification cycle. Expect that lane to take longer than the North American cross-sell.

Digi's chief executive also noted that the acquisition is the second deal involving the SmartSense team inside eighteen months, which he presented as evidence of a deliberate investment in a market he believes is still early. Guy Yehiav, president and senior vice president of SmartSense, described the combined architecture as a three-layer stack: differentiated sensing provides trusted ground-truth data, AI turns that data into intelligence, and workflows translate intelligence into a recommended next action. Digi's own framing calls that sequence Sense, Understand and Act, and it is worth noting that the acquisition strengthens only the bottom layer. The upper two layers are Digi's own, and they are the part customers will ultimately judge.

What could go wrong

The risk disclosures in the release itself deserve more attention than press releases usually get. Digi explicitly flags its ability to realize synergies, longer-than-expected sales cycles, supply chain challenges, cybersecurity and data privacy risks, and "the ability of companies like us to operate a global business in such conditions." The first and last of those are the ones that apply directly here.

Converting a hardware-weighted customer base into a subscription base requires those customers to accept a different commercial relationship, not just a different invoice. If facility operators have been buying sensors as a one-time capital expense with a multi-year useful life, being asked to move to a recurring fee for the same physical device is a genuine objection — particularly in the office and manufacturing verticals where the installed base sits. Digi's pitch is that the bundled model delivers more data and simpler maintenance; whether that is worth more per year than a sensor that costs almost nothing to install and runs for a decade is the commercial question the integration will have to answer.

Regulatory approval is also not yet done. The release states closing is expected before the end of 2026 but remains subject to approval, which leaves the integration timeline exposed to a regulatory calendar neither side controls.

Conclusion

The smart-home and consumer IoT market gets the attention, but the durable IoT businesses are increasingly being built in the least glamorous category of all: sensors that are cheap to make, cheap to install, and expensive to service. Digi International is paying $130 million in cash to get 250,000 of those sensors already buried in buildings across more than 25 countries, plus the European commercial relationships needed to reach them.

The strategic logic is coherent. Disruptive Technologies supplies a hardware advantage — custom ASIC, proprietary protocol, 15-year coin-cell life — that is genuinely hard to replicate quickly. Digi supplies the distribution, the cloud and the subscription motion that can turn a quarter-million endpoints into recurring revenue rather than one-time sales. Konezny's framing that you are buying a SmartSense solution of which Disruptive Technologies is a key part is the right way to understand the price.

Whether the $9 million of fiscal 2028 EBITDA and free cash flow materializes depends less on the silicon than on the commercial surgery required to move European and North American facility operators from buying sensors to subscribing to them.
