Fourth Quarter 2021 Financial Results

Sales for the fourth quarter of 2021 were $14.1 million, of which $2.5 million was generated from the consumer market, $8.1 million from the enterprise market and $3.5 million from the automotive market. Sales decreased by 8.5%, or $1.3 million in the fourth quarter of 2021 compared to $15.5 million in the third quarter of 2021. Consumer sales declined from the third quarter of 2021 by $2.1 million primarily due to continuing weakness from the global supply shortage impacting our customers' product sales. Enterprise product sales decreased from the third quarter of 2021 by $0.6 million due to continuing weakness from the global supply shortage. Lower enterprise WiFi product sales was offset by increased sales in industrial IoT products. Automotive sales increased $1.4 million from the third quarter of 2021 primarily due to growth in sales of AirgainConnect® products. Sales for the fourth quarter of 2021 increased by 10.2%, or $1.3 million from $12.8 million in the same year-ago period primarily due to increased sales of $6.8 million from the enterprise market, mainly due to sales of industrial IoT products and increased sales of $1.7 million from the automotive market offset by a decrease in sales of $7.2 million from the consumer market.

GAAP gross profit for the fourth quarter of 2021 was $4.9 million compared to $5.5 million for the third quarter of 2021 and $5.8 million in the same year-ago period. Non-GAAP gross profit for the fourth quarter of 2021 was $5.0 million,

compared to $5.6 million for the third quarter of 2021 and $5.9 million in the same year-ago period (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

GAAP gross margin for the fourth quarter of 2021 was 34.4%, compared to 35.9% for the third quarter of 2021 and 45.5% in the same year-ago period. The decrease in gross margin compared to the third quarter of 2021 was primarily due to changes in product mix including decreased sales of consumer products which yield a higher gross margin. The decrease in gross margin for the fourth quarter of 2021 compared to the same year-ago period was primarily due to changes in the product mix, including increased sales of industrial IoT devices with lower gross margins and a decrease in consumer sales that have higher gross margins, higher production and freight costs, and higher amortization costs associated with the NimbeLink acquisition. Non-GAAP gross margin for the fourth quarter of 2021 was 35.1% compared to 36.5% for the third quarter of 2021 and 45.8% in the same year-ago period. The decrease in non-GAAP gross margin from the third quarter of 2021 and the same year-ago period was primarily due to changes in product mix and the impact of ramping industrial IoT sales which yield a lower gross margin, as well as higher production and freight costs (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

GAAP operating expenses for the fourth quarter of 2021 were $9.3 million, compared to $8.6 million for the third quarter of 2021 and $6.9 million in the same year-ago period. Operating expenses were higher for the fourth quarter of 2021 compared to the third quarter of 2021 due to the change in the fair value of contingent consideration associated with the NimbeLink acquisition, higher travel and marketing costs and higher shipping and handling costs for products sold to our customers. The higher operating expenses for the fourth quarter of 2021 compared to the same year-ago period were primarily due to the NimbeLink acquisition which resulted in added headcount, facilities and IT expenses, higher amortization of intangible assets, higher outsourced service costs as well as a $0.4 million charge related to the change in fair value of contingent consideration associated with the NimbeLink acquisition. Non-GAAP operating expenses for the fourth quarter of 2021 were $7.2 million compared to $6.8 million in the third quarter of 2021 and $5.7 million in the same year-ago period (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

GAAP net loss for the fourth quarter of 2021 was $4.6 million or $(0.46) per share (based on 10.1 million shares), compared to $3.1 million or $(0.30) per share (based on 10.1 million shares) for the third quarter of 2021 and $1.1 million or $(0.11) per share (based on 9.8 million shares) in the same year-ago period. The increase in net loss compared to the third quarter of 2021 and the same year-ago period was due to lower gross profit, higher operating expenses and higher income tax provision. Non-GAAP net loss for the fourth quarter of 2021 was $2.3 million or $(0.23) per share (based on 10.1 million shares), compared to $1.1 million or $(0.11) per share (based on 10.1 million shares) for the third quarter of 2021 and a non-GAAP net income of $0.2 million or $0.02 per share (based on 10.2 million diluted shares) for the same year-ago period (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

Adjusted EBITDA for the fourth quarter of 2021 was $(2.1) million, compared to $(1.0) million for the third quarter of 2021 and $0.3 million in the same year-ago period (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

Sales increased by 32.5%, or $15.8 million for the full year of 2021 compared to $48.5 million in 2020. Consumer sales declined by $10.9 million from $37.1 million in 2020 primarily due to continuing weakness from the global supply shortage impacting our customers' product sales. Enterprise product sales increased $23.5 million from $3.9 million in 2020, primarily due to the sale of industrial IoT products. Automotive sales increased $3.2 million, from $7.5 million in 2020, primarily due to growth in sales of AirgainConnect® products.

GAAP gross profit for the full year of 2021 was $24.6 million compared to $22.6 million in 2020. Non-GAAP gross profit for the full year of 2021 was $25.3 million compared to $22.7 million in 2020 (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

GAAP gross margin for the full year of 2021 was 38.3%, compared to 46.6% in 2020. The decrease in gross margin was primarily due to changes in the product mix including increased sales of industrial IoT devices with lower gross margins, and higher production and freight costs as well as an inventory step-up adjustment and higher amortization costs associated with the NimbeLink acquisition. Non-GAAP gross margin for the full year of 2021 was 39.4%, compared to 46.8% in 2020 (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

GAAP operating expenses for the full year of 2021 were $36.7 million, compared to $25.8 million in 2020. The higher operating expenses were primarily due to the NimbeLink acquisition which resulted in added headcount, facilities and IT expenses and intangible asset amortization as well as a change in fair value of contingent consideration of $2.0 million. Non-GAAP operating expense for the full year of 2021 was $27.8 million, compared to $22.2 million in 2020 (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

GAAP net loss for the full year of 2021 was $10.1 million or $(1.01) per share (based on 10.0 million shares), compared to $3.3 million or $(0.34) per share (based on 9.7 million shares) in 2020. The increase in net loss was due to increased operating expenses, partially offset by increased gross profit and a $2.0 million tax benefit. In connection with the NimbeLink acquisition, deferred tax liabilities associated with the intangible assets and a $2.3 million release of the valuation allowance was recorded in the first quarter of 2021. Non-GAAP net loss for the full year of 2021 was $2.5 million or $(0.25) per share (based on 10.0 million shares), compared to non-GAAP net income of $0.5 million or $0.05 per share (based on 10.0 million diluted shares) in 2020 (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

Adjusted EBITDA for the full year of 2021 was $(2.0) million, compared to $0.9 million in 2020 (see note regarding "Use of Non-GAAP Financial Measures" below for further discussion of this non-GAAP measure).

Forward-Looking Statements

Airgain cautions you that statements in this press release that are not a description of historical facts are forward-looking statements. These statements are based on the company’s current beliefs and expectations. These forward-looking statements include statements regarding our first quarter 2022 financial outlook and demand for our products and prospects for future growth across our markets. The inclusion of forward-looking statements should not be regarded as a representation by Airgain that any of our plans will be achieved. Actual results may differ from those set forth in this press release due to the risk and uncertainties inherent in our business, including, without limitation: the market for our antenna products is developing and may not develop as we expect; our operating results may fluctuate significantly, including based on seasonal factors, which makes future operating results difficult to predict and could cause our operating results to fall below expectations or guidance; supply constraints on our and our customer's ability to obtain necessary components in our respective supply chains may negatively affect our sales and operating results; the COVID-19 pandemic may continue to disrupt and otherwise adversely affect our operations and those of our suppliers, partners, distributors and ultimate end customers, and the overall global supply shortage and logistics delays within the supply chain that our products are used in, as well as adversely affecting the general U.S. and global economic conditions and financial markets, and, ultimately, our sales and operating results; our products are subject to intense competition, including competition from the customers to whom we sell and competitive pressures from existing and new companies may harm our business, sales, growth rates, and market share; risks associated with the performance of our products; risks and uncertainties related to management and key personnel changes; our future success depends on our ability to develop and successfully introduce new and enhanced products for the wireless market that meet the needs of our customers, including our ability to transition to provide a more diverse solutions capability; we sell to customers who are price conscious, and a few customers represent a significant portion of our sales, and if we lose any of these customers, our sales could decrease significantly; we rely on a few contract manufacturers to produce and ship all of our products, a single or limited number of suppliers for some components of our products and channel partners to sell and support our products, and the failure to manage our relationships with these parties successfully could adversely affect our ability to market and sell our products; if we cannot protect our intellectual property rights, our competitive position could be harmed or we could incur significant expenses to enforce our rights; and other risks described in our prior press releases and in our filings with the Securities and Exchange Commission (SEC), including under the heading “Risk Factors” in our Annual Report on Form 10-K and any subsequent filings with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof and we undertake no obligation to revise or update this press release to reflect events or circumstances after the date hereof.

Note Regarding Use of Non-GAAP Financial Measures

To supplement our condensed financial statements presented in accordance with U.S. generally accepted accounting principles (GAAP), this earnings release and the accompanying tables and the related earnings conference call contain certain non-GAAP financial measures, including adjusted earnings before interest, taxes, depreciation, amortization (Adjusted EBITDA), non-GAAP net income (loss) attributable to common stockholders (non-GAAP net income (loss)), non-GAAP net income (loss) per (basic or diluted) share (non-GAAP EPS), non-GAAP operating expense, non-GAAP gross profit and non-GAAP gross margin. We believe these financial measures provide useful information to investors with which to analyze our operating trends and performance.

In computing Adjusted EBITDA, non-GAAP net income (loss), and non-GAAP EPS, we exclude stock-based compensation expense, which represents non-cash charges for the fair value of stock awards; interest income, net of interest expense offset by other expense; depreciation and/or amortization; change in the fair value of contingent consideration, acquisition-related expenses, amortization of inventory step-up and provision (benefit) for income taxes. In computing non-GAAP operating expense, we exclude stock-based compensation expense, amortization of intangibles, change in the fair value of contingent consideration and acquisition-related expenses. In computing non-GAAP gross profit and non-GAAP gross margin, we exclude stock-based compensation expense, amortization of inventory step-up and amortization of intangible assets. Because of varying available valuation methodologies, subjective assumptions, and the variety of equity

5

instruments that can impact a company’s non-cash operating expenses; we believe that providing non-GAAP financial measures that exclude non-cash expense allows for meaningful comparisons between our core business operating results and those of other companies, as well as providing us with an important tool for financial and operational decision making and for evaluating our own core business operating results over different periods of time. Management considers these types of expenses and adjustments, to a great extent, to be unpredictable and dependent on a significant number of factors that are outside of our control and are not necessarily reflective of operational performance during a period.

Our non-GAAP measures may not provide information that is directly comparable to that provided by other companies in our industry, as other companies in our industry may calculate non-GAAP financial results differently, particularly related to non-recurring, unusual items. Our Adjusted EBITDA, non-GAAP net income (loss), non-GAAP EPS, non-GAAP operating expense, non-GAAP gross profit and non-GAAP gross margin are not measurements of financial performance under GAAP and should not be considered as an alternative to operating or net income or as an indication of operating performance or any other measure of performance derived in accordance with GAAP. We do not consider these non-GAAP measures to be a substitute for, or superior to, the information provided by GAAP financial results. Reconciliations with specific adjustments to GAAP results and outlooks are provided at the end of this release.
