Record Quarterly Revenue of $122M, End of Quarter ARR of $157M

Cash Flow From Operations of $36M

Digi International Inc. ("Digi" or the "Company") (Nasdaq: DGII), a leading global provider of business and mission-critical Internet of Things ("IoT") products, services and solutions, today announced its financial results for its first fiscal quarter ended December 31, 2025.

First Fiscal Quarter 2026 Results Compared to First Fiscal Quarter 2025 Results¹

• Revenue was $122 million, an increase of 18%.

• Gross profit margin was 62.4%, an increase of 40 basis points.

• Operating margin was 13.3%, an increase of 40 basis points.

• Net income was $12 million, an increase of 16%.

• Net income per diluted share was $0.31, an increase of 15%.

• Adjusted net income was $21 million, an increase of 27%.

• Effective in the first fiscal quarter 2026, the Company has updated its calculation of adjusted net income and adjusted net income per share to include interest expense. Previously, interest was excluded from this non-GAAP measure as the Company operated without structural debt. Going forward, interest will be included to provide a more comprehensive view of operating performance and to align with evolving best practices. Adjusted net income per diluted share was $0.56, an increase of 24%, including a $0.06 impact from interest expense in both periods.

• Adjusted EBITDA was $32 million, an increase of 23%.

• Annualized Recurring Revenue (ARR) was $157 million at quarter end, an increase of 31%.

(1) Fiscal 2026 results include the results of Jolt.

Reconciliations of non-GAAP financial measures to their closest GAAP analogs appear at the end of this release, as well as a discussion of recent changes to the method of calculating adjusted net income and adjusted net income per share.

“We’re off to a great start to our fiscal year 2026. Digi’s customer focus is shining through our IoT solutions that drive meaningful ROI. With the addition of Jolt, we delivered double digit growth in ARR, revenue, adjusted EBITDA, and adjusted EPS in our fiscal first quarter,” stated Ron Konezny, President and CEO. “We are thrilled to have the Particle team join the Digi family. Particle’s unique solutions build and manage connected devices, and we have an aligned culture focused on customer value. Our strong cash generation propels a flywheel of organic growth complemented by select acquisitions.”

Additional Financial Highlights

• We made payments against our revolving credit facility of $24 million in the first quarter, reducing our outstanding debt as of the end of the first quarter to $135 million and a cash and cash equivalents balance of $31 million resulting in a debt net of cash and cash equivalents of $104 million.

• Cash flow from operations was $36 million in the first quarter of fiscal 2026, compared to $30 million in the first quarter of fiscal 2025. This change was driven primarily by a $5.1 million decrease in deferred income tax benefit in the first quarter of fiscal 2026 compared to a $0.5 million increase in the first quarter of fiscal 2025.

Segment Results

IoT Product & Services

The segment's first fiscal quarter 2026 revenue of $86 million increased 11% compared to the same period in the prior fiscal year. This consisted of a $6.3 million increase in one-time sales and $2.2 million of recurring revenue growth, with no material impact from pricing. ARR as of the end of the first fiscal quarter was $34 million, an increase of 26% from the end of the first fiscal quarter of 2025. This increase was due to growth in the subscription base across remote management platforms and extended warranty offerings and technical support. Operating margin decreased 60 basis points to 13.5% of revenue for the first fiscal quarter of 2026, driven by higher inventory related expenses offset by favorable product margin mix and operating expense leverage.

IoT Solutions

The segment's first fiscal quarter 2026 revenue of $36 million increased 39%, as compared to the same period in the prior fiscal year. The increase consisted of a $7.6 million increase in recurring revenue and a $2.5 million increase in one-time sales, both driven primarily by the Jolt acquisition. ARR as of the end of the first fiscal quarter was $123 million, an increase of 32% from the end of the first fiscal quarter of 2025, driven primarily by the acquisition of Jolt, as well as growth in both SmartSense and Ventus. Operating margins increased 370 basis points to 12.9% in the first fiscal quarter of 2026 compared to the prior fiscal year. This increase was the result of favorable operating expense leverage and a higher proportion of volume from recurring revenue, which has a higher margin.

Capital Allocation Strategy

We intend to continue to deleverage the Company's balance sheet.

Acquisitions remain a top capital priority for Digi as reflected by our acquisition of Particle announced on January 27. Particle is a leading provider of edge-to-cloud application infrastructure for intelligent devices that adds approximately $20 million of ARR to Digi’s IoT Products & Services segment.

We will continue to be disciplined in our approach and act when we believe an opportunity is appropriate to execute in the context of prevailing market conditions. We intend to focus more on scale and ARR.

Second Fiscal Quarter & Full Year Fiscal 2026 Guidance

The expansion of software applications and AI adoption continues to drive demand for hardware-enabled software solutions that address our customers’ most critical business needs. Our focus remains on delivering solutions that generate recurring revenue streams and create sustained value for customers well beyond the initial device purchase. We see continued growth and evolution in the Industrial Internet of Things market, reinforcing our confidence in achieving $200 million in both ARR and Adjusted EBITDA over the next three years. Strategic acquisitions aligned with these objectives could accelerate our path to these targets.

The market dynamics favor Digi’s solutions as customers increasingly recognize that legacy 'set it and forget it' approaches no longer meet their operational requirements. Organizations are prioritizing connectivity and software capabilities as fundamental enablers of their strategic initiatives. For fiscal 2026, our guidance reflects both our operational outlook and the January 2026 acquisition of Particle. We anticipate ARR growth of 23%, revenue growth of 14%-18%, and Adjusted EBITDA growth of 17-21%. The impact of Particle and its expected synergies to this guide is approximately $20 million to $22 million in ARR, $13 million to $14 million in Revenue, and $1 million to $2 million in Adjusted EBITDA. After capturing synergies, we expect Particle to contribute $5M to our FY27 Adjusted EBITDA. Particle will be integrated into our IoT P&S Segment and will not be reported on a stand-alone basis.

For the second fiscal quarter, revenues are estimated to be $124 million to $128 million. Adjusted EBITDA is estimated to be between $31.5 million and $33.0 million. New for fiscal 2026, we are including interest expense in our Adjusted net income per diluted share metric and we have done the same for comparison periods. Adjusted net income per diluted share is anticipated to be between $0.56 and $0.59 per diluted share, assuming a weighted average diluted share count of 38.8 million shares. This includes an expected impact from interest between $0.04 and $0.05 per diluted share.

We provide guidance or longer-term targets for Adjusted net income per share as well as Adjusted EBITDA targets on a non-GAAP basis. We do not reconcile these items to their most comparable U.S. GAAP measure as it is not possible to predict without unreasonable efforts numerous items that include but are not limited to the impact of foreign exchange translation, restructuring, interest and certain tax-related events. Given the uncertainty, any of these items could have a significant impact on U.S. GAAP results.

Presentation of Non-GAAP Financial Measures

This release includes adjusted net income, adjusted net income per diluted share and Adjusted EBITDA (defined below), each of which is a non-GAAP measure.

During the first fiscal quarter of 2026, Digi modified its method of calculating adjusted net income and adjusted net income per share to include the impact of interest expense. This change was primarily driven by the continued use of financing by the Company to fund cash flows needs and therefore including the recurring nature of interest presents a better metric by which management believes provides a more representative view of operating performance and cash-generating capability. Accordingly, we evaluated the impact of this change on prior-period disclosures and have recast adjusted net income and adjusted net income per share for all periods to conform to this presentation.

We understand that there are material limitations on the use of non-GAAP measures. Non-GAAP measures are not substitutes for GAAP measures, such as net income, for the purpose of analyzing financial performance. The disclosure of these measures does not reflect all charges and gains that were actually recognized by Digi. These non-GAAP measures are not in accordance with, or an alternative for measures prepared in accordance with, generally accepted accounting principles and may be different from non-GAAP measures used by other companies or presented by us in prior reports. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. We believe that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP. We believe these measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. Additionally, Adjusted EBITDA does not reflect our cash expenditures, the cash requirements for the replacement of depreciated and amortized assets, or changes in or cash requirements for our working capital needs.

We believe that providing historical and adjusted net income and adjusted net income per diluted share, respectively, exclusive of such items as reversals of tax reserves, discrete tax benefits, restructuring charges and reversals, intangible amortization, stock-based compensation, other non-operating income/expense, changes in fair value of contingent consideration and acquisition-related expenses related to acquisitions permits investors to compare results with prior periods that did not include these items. Management uses the aforementioned non-GAAP measures to monitor and evaluate ongoing operating results and trends and to gain an understanding of our comparative operating performance. In addition, certain of our stockholders have expressed an interest in seeing financial performance measures exclusive of the impact of these matters, which while important, are not central to the core operations of our business. Management believes that "Adjusted EBITDA", defined as EBITDA adjusted for stock-based compensation expense, acquisition-related expenses, restructuring charges and reversals, and changes in fair value of contingent consideration, is useful to investors to evaluate our core operating results and financial performance because it excludes items that are significant non-cash or non-recurring items reflected in the Condensed Consolidated Statements of Operations. We believe that presenting Adjusted EBITDA as a percentage of revenue is useful because it provides a reliable and consistent approach to measuring our performance year over year and in assessing our performance against that of other companies. We believe this information helps compare operating results and corporate performance exclusive of the impact of our capital structure and the method by which assets were acquired.
