Non-GAAP Financial Measures

In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), this press release and accompanying tables include certain non-GAAP financial measures. The non-GAAP financial measures contained herein are a supplement to the corresponding financial measures prepared in accordance with U.S. GAAP. The non-GAAP financial measures presented exclude the items described below. Management believes that adjustments for these items assist investors in making comparisons of period-to-period operating results. Furthermore, management also believes that these items are not indicative of our on-going core operating performance. These non-GAAP financial measures have certain limitations in that they do not reflect all of the costs associated with the operations of our business as determined in accordance with GAAP.

Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. The non-GAAP financial measures presented by us may be different from the non-GAAP financial measures used by other companies.

We have presented the following non-GAAP measures to assist investors in understanding our core net operating results on an on-going basis: (i) Contribution Margin; (ii) Contribution margin as a percentage of net revenue; (iii) EBITDA (iv) Adjusted EBITDA; and (v) Adjusted EBITDA as a percentage of net revenue. These non-GAAP financial measures may also assist investors in making comparisons of our core operating results with those of other companies.

As used herein, Contribution margin represents gross profit less amortization of inventory step-up from acquisitions (included in cost of goods sold) and e-commerce platform commissions, online advertising, selling and logistics expenses (included in sales and distribution expenses). As used herein, Contribution margin as a percentage of net revenue represents Contribution margin divided by net revenue. As used herein, EBITDA represents net loss plus depreciation and amortization, interest expense, net and provision for income taxes. As used herein, Adjusted EBITDA represents EBITDA plus stock-based compensation expense, changes in fair-market value of earn-outs, amortization of inventory step-up from acquisitions (included in cost of goods sold), changes in fair-market value of warrant liability, professional fees related to acquisitions, loss from extinguishment of debt and other expenses, net. As used herein, Adjusted EBITDA as a percentage of net revenue represents Adjusted EBITDA divided by net revenue. Contribution margin, EBITDA and Adjusted EBITDA do not represent and should not be considered as alternatives to loss from operations or net loss, as determined under GAAP.

We present Contribution margin and Contribution margin as a percentage of net revenue, as we believe each of these measures provides an additional metric to evaluate our operations and, when considered with both our GAAP results and the reconciliation to gross profit, provides useful supplemental information for investors. Specifically, Contribution margin and Contribution margin as a percentage of net revenue are two of our key metrics in running our business. All product decisions made by us, from the approval of launching a new product and to the liquidation of a product at the end of its life cycle, are measured primarily from Contribution margin and/or Contribution margin as a percentage of net revenue. Further, we believe these measures provide improved transparency to our stockholders to determine the performance of our products prior to fixed costs as opposed to referencing gross profit alone.

In the reconciliation to calculate contribution margin, we add e-commerce platform commissions, online advertising, selling and logistics expenses (“sales and distribution variable expense”), to gross margin to inform users of our financial statements of what our product profitability is at each period prior to fixed costs (such as sales and distribution expenses such as salaries as well as research and development expenses and general administrative expenses). By excluding these fixed costs, we believe this allows users of our financial statements to understand our products performance and allows them to measure our products performance overtime. 

We present EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue because we believe each of these measures provides an additional metric to evaluate our operations and, when considered with both our GAAP results and the reconciliation to net loss, provide useful supplemental information for investors. We use these measures with financial measures prepared in accordance with GAAP, such as sales and gross margins, to assess our historical and prospective operating performance, to provide meaningful comparisons of operating performance across periods, to enhance our understanding of our operating performance and to compare our performance to that of our peers and competitors. We believe EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue are useful to investors in assessing the operating performance of our business without the effect of non-cash items.

Contribution margin, Contribution margin as a percentage of net revenue, EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue should not be considered in isolation or as alternatives to net loss, loss from operations or any other measure of financial performance calculated and prescribed in accordance with GAAP. Neither EBITDA, Adjusted EBITDA or Adjusted EBITDA as a percentage of net revenue should be considered a measure of discretionary cash available to us to invest in the growth of our business. Our Contribution margin, Contribution margin as a percentage of net revenue, EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue may not be comparable to similar titled measures in other organizations because other organizations may not calculate Contribution margin, Contribution margin as a percentage of net revenue, EBITDA, Adjusted EBITDA or Adjusted EBITDA as a percentage of net revenue in the same manner as we do. Our presentation of Contribution margin and Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by the expenses that are excluded from such terms or by unusual or non-recurring items.

We recognize that EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue, have limitations as analytical financial measures. For example, neither EBITDA nor Adjusted EBITDA reflects:

  • our capital expenditures or future requirements for capital expenditures or mergers and acquisitions;
  • the interest expense or the cash requirements necessary to service interest expense or principal payments, associated with indebtedness;
  • depreciation and amortization, which are non-cash charges, although the assets being depreciated and amortized will likely have to be replaced in the future, or any cash requirements for the replacement of assets;
  • changes in cash requirements for our working capital needs; or
  • changes in fair value of contingent earn-out liabilities, warrant liabilities, and amortization of inventory step-up from acquisitions (included in cost of goods sold).

Additionally, Adjusted EBITDA excludes non-cash expense for stock-based compensation, which is and is expected to remain a key element of our overall long-term incentive compensation package.

We also recognize that Contribution margin and Contribution margin as a percentage of net revenue have limitations as analytical financial measures. For example, Contribution margin does not reflect:

  • general and administrative expense necessary to operate our business;
  • research and development expenses necessary for the development, operation and support of our software platform;
  • the fixed costs portion of our sales and distribution expenses including stock-based compensation expense; or
  • changes in fair value of contingent earn-out liabilities, warrant liabilities, and amortization of inventory step-up from acquisitions (included in cost of goods sold).


Adjusted EBITDA

EBITDA represents net loss plus depreciation and amortization, interest expense, net and provision for income taxes. Adjusted EBITDA represents EBITDA plus stock-based compensation expense, changes in fair-market value of earn-outs, amortization of inventory step-up from acquisitions (included in cost of goods sold), change in fair-market value of warrant liability, professional fees related to acquisitions, loss from extinguishment of debt and other expenses, net. As used herein, Adjusted EBITDA as a percentage of net revenue represents Adjusted EBITDA divided by net revenue. 

The following table provides a reconciliation of EBITDA and Adjusted EBITDA to net loss, which is the most directly comparable financial measure presented in accordance with GAAP:

Each of our products typically goes through the Launch phase and depending on its level of success is moved to one of the other phases as further described below:

i.        Launch phase: During this phase, we leverage our technology to target opportunities identified using AIMEE (Artificial Intelligence Marketplace e-Commerce Engine) and other sources. During this period of time, due to the combination of discounts and investment in marketing, our net margin for a product could be as low as approximately negative 35%. Net margin is calculated by taking net revenue less the cost of goods sold, less fulfillment, online advertising and selling expenses. These costs primarily reflect the estimated variable costs related to the sale of a product.

ii.        Sustain phase: Our goal is for every product we launch to enter the sustain phase and become profitable, with a target of positive 15% net margin for most products, within approximately three months of launch on average. Over time, our products benefit from economies of scale stemming from purchasing power both with manufacturers and with fulfillment providers.

iii.        Milk phase or Liquidate phase: If a product does not enter the sustain phase or if the customer satisfaction of the product (i.e., ratings) is not satisfactory, then it will go to the liquidate phase and we will sell through the remaining inventory. In order to enter the milk phase, a product must be well received and become a strong leader in its category in both customer satisfaction and volume sold as compared to its competition. Products in the milk phase that have achieved profitability should benefit from pricing power and we expect their profitability to increase accordingly. To date, none of our products have achieved the milk phase and we can provide no assurance that any of our products will do so in the future.
