Digi International closed fiscal 2026 with a quarter that was strong on paper but not quite strong enough for the most optimistic investors. Adjusted earnings of $0.78 per share topped the $0.76 consensus but fell short of the $0.80 Earnings Whisper number, a 2.5% miss against the whisper. Revenue of $143.32 million beat the $140.43 million consensus by 2.1%. Year over year, earnings grew 41.8% and revenue grew 25.3%, both records for the company. The central tension is not the quarter itself. It is the outlook. Management's fiscal 2027 guidance calls for revenue growth of 10-15%, adjusted EBITDA growth of 12.5-17.5% and ARR growth of at least 15%. Those figures include the pending Disruptive Technologies acquisition and still represent a sharp step down from the roughly 24% revenue growth Digi just delivered.

The operating leverage in the quarter was real. GAAP operating margin expanded 400 basis points to 16.5%, and operating expenses fell to about 47% of revenue from 51%. G&A actually declined in absolute dollars. GAAP diluted EPS rose to $0.38 from $0.26, despite a tax provision that nearly tripled. Both segments widened margins:

• **IoT Products & Services:** operating margin rose 320 basis points to 18.4%.
• **IoT Solutions:** operating margin rose 590 basis points to 11.5%.

The mix of growth deserves some scrutiny, however. In Products & Services, $15.0 million of the revenue increase came from one-time sales versus $7.7 million from recurring revenue. That segment's 100% ARR jump was driven primarily by the Particle acquisition. In Solutions, most of the 20% revenue growth came from Jolt, while organic ARR grew a more modest 11% to $133 million. Gross margin also slipped to 63.7%, down from 64.8% in the third quarter. Finally, the $42 million of fourth-quarter operating cash flow was flattered by deferred-tax benefits tied to the One Big Beautiful Bill Act.

The call preserved a credible demand story:

• Management described the opportunity pipeline as up double digits and at an all-time high.
• Deal registrations hit a record.
• OpenGear growth was broad across every region, and the company is still pursuing hyperscalers.
• Total ARR reached $197 million, and the $200 million ARR goal is now expected in fiscal 2027, a year ahead of plan.

The year's execution was impressive. Fiscal 2026 began with a 14-18% revenue growth outlook and ended at about 24%, with ARR expectations raised on every call. Against that record of beat-and-raise, a 10-15% guide that already includes an acquisition reads as conspicuously conservative or genuinely cautious. The $200 million adjusted EBITDA target remains a fiscal 2028 objective, and management acknowledged there is still work to do.

The new risks are concrete. Supply-chain commentary escalated meaningfully. Memory pressure that surfaced earlier in the year has broadened into component cost and allocation problems tied to the AI data-center build-out. That has forced Digi to extend demand planning to 9-12 months and push through selective price increases. First-quarter gross margin is guided to the middle of the low-to-mid-60s range. Adjusted EBITDA of $39.5-41.0 million would be down sequentially, which management attributed to seasonal costs, mix and channel inventory tightening. Improvement in sales cycles also slowed amid election-related hesitation.

The Disruptive Technologies deal is a genuine catalyst. It brings long-life sensors, a European channel and cross-selling routes through cellular, OpenGear and Particle. But management framed fiscal 2027 as a transition year as DT converts from one-time sensor sales to a subscription model. The $130 million cash price will be funded on the revolver. That will reverse much of the deleveraging that brought net debt down to $39 million from $81 million last quarter.

The market had already begun pricing in a cooler setup. Shares spiked to a 52-week high of $86.84 the day after the August report, then surrendered all of it. The stock sits at $65.05, down 15.4% from the post-report open and 25% below that peak. Shares are just 6% above the November 5 inter-earnings low and only 2% above the 200-day moving average. Investor sentiment slipped from mildly positive to mildly negative heading into the report, a meaningful but not extreme shift. Underlying sequential growth and momentum readings remain constructive, while the AVWAP trend is negative, consistent with a stock that has been distributed since August.

The bottom line is that Digi delivered the best year in its history, with real margin leverage and an ARR milestone arriving early. But the quarter was not clean enough to clear the whisper, and the fiscal 2027 outlook resets growth expectations sharply lower. Rising component costs and a transition-year acquisition add execution risk. Bulls can argue the guide is conservative from a company that beat every target in 2026. Bears have legitimate ammunition in decelerating organic ARR, slipping gross margins and a sequential EBITDA dip, all with the stock hovering just above long-term trend support.
