Digi International stock rises 3%, with no confirmed new catalyst

The market data puts Digi International shares up 3.0% today, October 5, 2026, at $75.61. It does not identify a cause, and the documents available here do not establish that a particular announcement or event drove the move. A daily price change is observable; its explanation is not.

The latest verified company results are from August 5, when Digi reported its third fiscal quarter ended June 30. That release cannot by itself explain a move on October 5. Recent headlines include an October 1 report about a proposed acquisition, but headlines are leads, not evidence: no attached primary document verifies its terms, status or expected financial effect. We therefore do not attribute today's rise to it.

Digi reported third-quarter revenue of $138.7 million, up 29% year over year, and ARR of $191 million, up 52%. Operating margin rose to 16.5% from 13.9%, while GAAP diluted EPS increased to $0.40 from $0.27. The numbers show stronger profitability alongside the top-line growth (Digi International Reports Third Fiscal Quarter 2026 Results).

The composition matters. IoT Products & Services revenue grew 25%; Digi attributed most of the increase to organic customer demand, supported by Particle, and reported no material pricing impact. Its ARR doubled to $60 million, driven primarily by Particle. IoT Solutions revenue rose 41%, but the significant majority of increases in both recurring revenue and one-time sales came from Jolt. Those acquisitions help explain why consolidated growth is brisk; they also make it harder to read the headline ARR growth as a like-for-like acceleration in the existing business.

Management raised its fiscal 2026 outlook: revenue guidance is $529 million to $533 million and adjusted EBITDA guidance is $146.0 million to $147.5 million. These are forecasts, not results. Adjusted EBITDA is a non-GAAP measure; Digi cautions that it does not capture cash expenditures, asset replacement costs or working-capital needs. The reported $110.4 million of operating cash flow covers the first nine months of fiscal 2026, not the full year.

At $75.61, DGII trades at 60.0× trailing GAAP earnings, based on the TTM EPS of $1.26. That multiple asks investors to pay for substantial future growth. The fiscal 2025 figures show 2.4% revenue growth and a 5.6% ROIC; the more recent quarter is stronger, but includes acquisitions and does not erase the valuation hurdle.

There is no prior SageNoodle fair value to carry forward, so this is a preliminary scenario estimate, not an established target. We use the midpoint of Digi's fiscal 2026 adjusted EBITDA guidance, $146.75 million, and an analyst-assumed 17× EV/EBITDA multiple in the base case. Subtracting $81 million of net debt, reported at June 30, from the resulting $2,494.75 million enterprise value gives $2,413.75 million of equity value. Dividing by 38.919 million diluted weighted-average shares reported for the quarter gives about $62.0 per share. At $75.61, the market price is about 22% above that estimate. The multiple is an assumption, not a market fact; at this price, the market is effectively assigning more value to future growth than our base case does.

The bear case uses 14× the low end of guidance, $146.0 million: ($2,044 million enterprise value − $81 million net debt) ÷ 38.919 million shares = $50.4 per share. The bull case uses 20× the high end, $147.5 million: ($2,950 million − $81 million) ÷ 38.919 million = $73.7. These cases illustrate the sensitivity to the multiple. Even the bull case is below today's supplied price, before any new information not included in the verified documents.

The long-term case is that Digi can turn installed connectivity products into durable subscription, service and support revenue, while acquiring businesses that widen its offering. The third-quarter release supports parts of that case: services revenue grew, ARR increased and operating margin expanded. But acquisitions supplied much of the growth in IoT Solutions ARR, and the contribution from Particle to consolidated revenue and operating income was described as not material in the 10-Q (Form 10-Q for the quarter ended June 30, 2026). That makes the durability and organic share of growth a real test, not a settled conclusion.

The near-term evidence to watch is the next reported quarter and fiscal-year results: whether guidance converts into revenue and adjusted EBITDA, whether existing businesses keep adding recurring revenue, and whether margins withstand rising component costs. Digi also said it intends to continue deleveraging; at June 30, it reported $109 million of debt and $28 million of cash. Until a primary announcement or fresh results clarify the current move, today's 3.0% rise has no verified company-specific explanation.
