Yaniv Sarig, Co-Founder and Chief Executive Officer, commented, “Despite the challenges e-commerce faced with strains on the global supply chain throughout the first quarter, Aterian remains well-positioned to capitalize on the continued global acceleration of e-commerce adoption and expanding market opportunities in the long-term. Due to extreme shortages of containers and backlogs of ships at the Long Beach Port, we suffered from stockouts on some of our top SKUs aggregating to an estimate of approximately $6 million of missed revenue. However, our sourcing, supply chain and operations team continues to work diligently to resolve these issues and we are continuing to monitor this global crisis closely.”

“As a market leading technology-enabled consumer products platform that builds, acquires and partners with best-in-class e-commerce brands, we are happy to announce today that we have closed our previously announced acquisition of Photo Paper Direct. We are excited to formally welcome our first European-based brand to Aterian’s portfolio and pleased about our entrance in the printing supplies category.” Sarig continued, “I am also thrilled to announce the acquisition of Squatty Potty, a category creator with a strong brand and broad customer base. We believe that the business’s significant online presence and brand equity can be further enhanced through investments in international expansion and the launch of additional products. As we bring this brand into the Aterian family, we continue to demonstrate our ability to operate across diverse product categories through leveraging our proprietary technology and agile supply chain. We look forward to building on the strength of this brand.”

Acquisition of Squatty Potty Assets

Aterian has acquired the business of e-commerce and retail company Squatty Potty, LLC (“Squatty Potty”), a leading online seller of health and wellness products in an asset purchase transaction. Founded in 2011, Squatty Potty is a consumer products company whose product lines consist of toilet stools, sprays and other bathroom accessories. Its flagship product, the Squatty Potty stool, is designed to help users assume the squatting position while using the bathroom, delivering fast, complete elimination with comfort and ease. Over the past year, Squatty Potty has diversified and scaled its product offerings while broadening its reach globally. Currently, Squatty Potty products are sold in thousands of retail locations including Bed, Bath & Beyond, Walmart and Target.

Squatty Potty’s unaudited trailing twelve month revenue and operating income, as of March 31, 2021, were approximately $16.8 million and $4.7 million, respectively. As consideration for Squatty Potty’s assets, Aterian paid approximately $19.0 million in cash. The cash payment reflects an approximate 4.0x multiple on the trailing twelve month operating income of Squatty Potty as of March 31, 2021. Aterian also paid approximately $1.1 million as consideration related to acquired inventory. In addition, and subject to the achievement of contribution margin metrics for the year ended December 31, 2021, Aterian agreed to pay Squatty Potty a maximum earnout of approximately $4.0 million, payable in stock or cash at the seller’s discretion. Aterian also agreed to pay Squatty Potty $8.0 million for transition services, payable in stock or cash at the seller’s discretion.

Closing of Photo Paper Direct Acquisition

Aterian today announced it has closed the acquisition of all outstanding stock of e-commerce company Photo Paper Direct Ltd. (“Photo Paper Direct’’), a leading online seller of printing supplies. Photo Paper Direct’s unaudited trailing twelve month revenue and operating income, as of December 31, 2020, were approximately $14.6 million and $3.9 million, respectively. As consideration for Photo Paper Direct’s stock, Aterian paid approximately $8.28 million in cash and issued approximately 704,500 shares of Aterian’s common stock. The cash and common stock payments reflect an approximate 4.7x multiple on the trailing twelve month operating income of Photo Paper Direct as of December 31, 2020. Aterian also agreed to pay

approximately $5.4 million in cash as consideration related to Photo Paper Direct’s inventory and other working capital assets, including cash on hand of approximately $3.0 million. In addition, and subject to the achievement of certain Adjusted EBITDA metrics by December 31, 2021, Aterian agreed to issue to Photo Paper Direct a maximum earnout of $6.0 million in cash and $2.0 million in Aterian common stock. In connection with the transaction, the former shareholders of Photo Paper Direct signed a five year voting and standstill agreement. This is Aterian’s first European acquisition.

2021 Outlook

As a result of the Squatty Potty acquisition, the Company expects net revenue for full year 2021 to be in the range of $360 million to $390 million up from $350 million to $380 million. For full year 2021, the Company expects Adjusted EBITDA to remain in the range of $30.0 million to $34.0 million.

The most directly comparable GAAP financial measure for Adjusted EBITDA is net loss and we expect to report a net loss for the twelve months ending December 31, 2021, due primarily to quarterly interest expense, net, fair value changes on contingent earnout liabilities from our acquisitions, fair value changes from warrant liabilities from our financings and stock-based compensation expense.

Non-GAAP Financial Measures

For more information on our non-GAAP financial measures and a reconciliation of GAAP to non-GAAP measures, please see the “Non-GAAP Financial Measures and Reconciliations” section below.

Net income is the most directly comparable GAAP financial measure for Adjusted EBITDA. The Company has not reconciled its expectations as to forward-looking Adjusted EBITDA to net income, the most directly comparable GAAP financial measure, because certain items are out of the Company’s control or cannot be reasonably predicted, including that the historical revenue and operating income of Photo Paper Direct and Squatty Potty may not be representative of future revenue and operating income, fair value changes on contingent earnout liabilities from our acquisitions, fair value changes from warrant liabilities from our financings and any other potential acquisitions to be completed that are subject to the completion of the Company’s standard procedures for the preparation and completion of its financial statements and completion of an audit by the Company’s independent registered public accounting firm. Accordingly, a reconciliation of forward-looking Adjusted EBITDA to net income is not available without unreasonable effort.

Non-GAAP Financial Measures and Reconciliations

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 the Company’s 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 the Company’s 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 the Company may be different from the non-GAAP financial measures used by other companies.

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

As used herein, Contribution margin represents operating loss plus general and administrative expenses, research and development expenses and fixed sales and distribution expenses including stock-based compensation expense. 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 income tax expense. As used herein, Adjusted EBITDA represents EBITDA plus stock-based compensation expense and other expense, 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, Contribution margin as a percentage of net revenue, 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, provides useful supplemental information for investors. We use Contribution margin, Contribution margin as a percentage of net revenue, EBITDA, Adjusted EBITDA and Adjusted EBITDA as a percentage of net revenue, together 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, while Contribution margin and Contribution margin as a percentage of net revenue are useful to investors in assessing the operating performance of our products as they represent our operating results without the effects of fixed costs and 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 nor 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, 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; or

• changes in cash requirements for our working capital needs;

• 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) and transition costs from acquisitions.

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

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

Adjusted EBITDA as a percentage of net revenue		(25.0	)%		(2.6	)%

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 expenses necessary to operate our business;

• research and development expenses necessary for the development, operation and support of our software platform; or

• the fixed costs portion of our sales and distribution expenses including stock-based compensation expense;

• changes in fair value of contingent earn-out liabilities, and amortization of inventory step-up from acquisitions (included in cost of goods sold).

The following table provides a reconciliation of Contribution Margin to operating loss, which is the most directly comparable financial measure presented in accordance with GAAP (in thousands):

	Three Months Ended March 31,
	2020			2021

We believe each of our products goes through three core phases as follows:

i. Launch phase: During this phase, we leverage our technology to target opportunities identified using AIMEE. During this period of time, and due to the combination of discounts and investment in marketing, our net margin for a product could be as low as negative 35%. In general, a product may stay in the launch phase on average for 3 months.

ii. Sustain phase: Our goal is for every product we launch to enter the sustain phase and become profitable, with a target average of positive 10% net margin (i.e. contribution margin). Over time, our products benefit from economies of scale stemming from purchasing power both with manufacturers and with fulfillment providers.

iii. Liquidate phase: If a product does not enter the sustain phase or if the customer satisfaction of the product (i.e., ratings) are not satisfactory, then it will go to the liquidate phase and we will sell the remaining inventory.

The following table breaks out our quarterly results of operations by our product phases including our PaaS business line :
