Published on

Digi International(R) Inc. (NASDAQ:DGII) (www.digi.com) reported revenue of $51.6 million for the fourth fiscal quarter of 2014, compared with $51.4 million for the fourth fiscal quarter of 2013, an increase of $0.2 million, or 0.5%. Net income was $0.4 million, or $0.02 per diluted share, in the fourth fiscal quarter of 2014 compared to net income of $2.0 million, or $0.08 per diluted share, in the year ago comparable quarter.

“We ended a tough year on a solid revenue note, and with what we believe is positive traction for fiscal 2015. This was highlighted by our overall revenue performance of $51.6 million in the fourth quarter,” said Joe Dunsmore, President and Chief Executive Officer. “This is the highest revenue we’ve achieved in the past twelve quarters, and represents 7.8% sequential growth over third quarter. We experienced continued sales momentum throughout the fourth quarter and we expect this to continue as we move into fiscal 2015.”

Revenue from growth hardware products in the fourth fiscal quarter of 2014 increased by 9.4% compared to the same quarter in the prior fiscal year. Revenue from cellular gateways was particularly strong, driven by key customer projects such as those described in the Business Highlights section later in this release.

  • Service revenue was under pressure all year as customers cancelled or deferred projects that were not replaced.

Forward-Looking Statements

This press release contains forward-looking statements that are based on management’s current expectations and assumptions. These statements often can be identified by the use of forward-looking terminology such as “anticipate,” “believe,” “estimate,” “may,” “will,” “expect,” “plan,” “project,” “should,” or “continue” or the negative thereof or other variations thereon or similar terminology. Among other items, these statements relate to expectations of the business environment in which the company operates, projections of future performance, perceived marketplace opportunities and statements regarding our mission and vision. Such statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, including risks related to the highly competitive market in which our company operates, rapid changes in technologies that may displace products sold by us, declining prices of networking products, risks associated with the retirement of our CEO announced in April 2014 and the associated transition to a new CEO who has not yet been appointed, our reliance on distributors and other third parties to sell our products, delays in product development efforts, uncertainty in user acceptance of our products, the ongoing shift of our sales efforts to focus more on the delivery of broader based solutions which can be a more complex sales process, has not been a historical sales focus of our company and can involve longer sales cycles than the sale of our legacy hardware products, the ability to integrate our products and services with those of other parties in a commercially accepted manner, potential liabilities that can arise if any of our products have design or manufacturing defects, our ability to defend or settle satisfactorily any litigation, uncertainty in global economic conditions and economic conditions within particular regions of the world which could negatively affect product demand and the financial solvency of customers and suppliers, the impact of natural disasters and other events beyond our control that could negatively impact our supply chain and customers, the ability to achieve the anticipated benefits and synergies associated with acquisitions, and changes in our level of revenue or profitability which can fluctuate for many reasons beyond our control. These and other risks, uncertainties and assumptions identified from time to time in our filings with the Securities and Exchange Commission, including without limitation, our annual report on Form 10-K for the year ended September 30, 2013 and other subsequent filings, could cause the company’s future results to differ materially from those expressed in any forward-looking statements made by us or on our behalf. Many of such factors are beyond our ability to control or predict. These forward-looking statements speak only as of the date for which they are made. We disclaim any intent or obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

Presentation of Non-GAAP Financial Measures

This release includes non-GAAP operating income and net income and net income per diluted share data, and earnings before interest, taxes, depreciation and amortization (EBITDA), which is a non-GAAP measure.

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 operating income or 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 the company. 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. 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 and that these measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. Additionally, we understand that 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 operating income and net income and net income per diluted share exclusive of such items as legal settlements, restructuring expenses, and reversals of tax reserves and discrete tax benefits 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 matters such as the impact of decisions relating to taxes and restructuring, which while important, are not central to the core operations of our business. Additionally, management believes that the presentation of EBITDA as a percentage of revenue is useful to investors because it provides a reliable and consistent approach to measuring our performance from year to year and in assessing our performance against that of other companies. Management believes that such information helps investors compare operating results and corporate performance exclusive of the impact of our capital structure and the method by which assets were acquired. EBITDA is used as an internal metric for executive compensation, as well as incentive compensation for the rest of the employee base, and it is monitored quarterly for these purposes.
