About Key Operating Metrics
We consider annual recurring revenue (“ARR”) as a key operating metric and a key indicator of our overall business. We also use ARR as one of the primary methods for planning and forecasting overall expectations and for evaluating, on at least a quarterly and annual basis, actual results against such expectations.
We manage customers through two primary channels, Enterprise and Partner and Marketplace. Enterprise channel consists of our larger customers and organizations, including those with non-platform custom websites, who generally engage directly with AudioEye sales personnel for custom pricing and solutions. This channel also includes federal, state and local government agencies. The Partner and Marketplace channel consists of our CMS partners, platform & agency partners, authorized resellers and our marketplace. This channel serves small and medium sized businesses who are on a partner or reseller’s web-hosting platform or who purchase an AudioEye solution from our marketplace.
We define ARR as the sum of (i) for our Enterprise channel, the total of the annualized recurring fee at the date of determination under each active contract, plus (ii) for our Partner and Marketplace channel, the annual or monthly recurring fee for all active customers at the date of determination, in each case, assuming no changes to the subscription, multiplied by 12 if applicable. Recurring fees are defined as revenues expected to be generated from services typically offered as a subscription service or annual service offering such as our automation and platform, periodic auditing, human-assisted technological fixes, legal support and professional service offerings and other services that reoccur on a multi-year contract. This determination includes both annual and monthly contracts for recurring products. Some of our contracts are terminable prior to the expected term, which may impact future ARR. ARR excludes non-recurring fees, which are defined as revenue expected to be generated from services typically not offered as a subscription service or annual service offering such as our PDF remediation services business, one-time mobile application reports, and other miscellaneous services that are offered as non-subscription services or are expected to be one-time in nature.
Use of Non-GAAP Financial Measures
From time to time, we review adjusted financial measures that assist us in comparing our operating performance consistently over time, as such measures remove the impact of certain items, as applicable, such as our capital structure (primarily interest charges), certain non-cash items, including stock compensation and depreciation and amortization expense, and other expenses that do not relate to our core operations, including significant transaction and litigation-related expenses and other costs that are expected to be non-recurring. In order to provide investors with greater insight and allow for a more comprehensive understanding of the information used in our financial and operational decision-making, the Company has supplemented the consolidated financial statements presented on a GAAP basis in this press release with the following non-GAAP financial measures: Adjusted EBITDA, Adjusted EBITDA margin, Adjusted earnings (loss) per diluted share (adjusted EPS) and Adjusted gross margin.
These non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of Company results as reported under GAAP. The Company compensates for such limitations by relying primarily on our GAAP results and using non-GAAP financial measures only as supplemental data. We also provide a reconciliation of non-GAAP to GAAP measures used. Investors are encouraged to carefully review this reconciliation. In addition, because these non-GAAP measures are not measures of financial performance under GAAP and are susceptible to varying calculations, these measures, as defined by us, may differ from and may not be comparable to similarly titled measures used by other companies.
Adjusted EBITDA, Adjusted EBITDA Margin, and Adjusted Earnings (Loss) per Diluted Share
We define: (i) Adjusted EBITDA as net income (loss), plus (less) interest expense (income), plus depreciation and amortization expense, plus stock-based compensation expense, plus (less) change in fair value of contingent consideration, plus certain litigation expense, plus certain acquisition expense, plus certain severance expense, plus loss on disposal or impairment of long-lived assets,
