Special Note Regarding Forward-Looking Statements

This Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including statements regarding our expectations, beliefs, intentions and strategies regarding the future. We intend that such forward-looking statements be subject to the safe-harbor provided by the Private Securities Litigation Reform Act of 1995. From time to time, we also provide forward-looking statements in other materials we release to the public as well as verbal forward-looking statements. These forward-looking statements include, without limitation, statements regarding: the impact of the COVID-19 pandemic; proposed products and services and related development efforts and activities; expectations about the market for our current and future products and services; the impact of pending litigation; trends relating to subscription plan programs and revenues; our anticipation that contracts with governmental customers will be fulfilled; expected trends, including the benefits of, research and development investments; the sufficiency of our liquidity and financial resources; that we may repurchase our common stock; expectations about customer behavior; the impact on our investment portfolio of changes in interest rates; trends in the percentage of our revenues denominated in foreign currencies; our potential use of foreign currency forward and option contracts; statements concerning projections, predictions, expectations, estimates or forecasts as to our business, financial and operational results and future economic performance; statements of management’s strategies, goals and objectives and other similar expressions; as well as the ultimate resolution of financial statement items requiring critical accounting estimates, including those set forth in our Form 10-K for the year ended December 31, 2019. Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. Words such as “may,” “will,” “should,” “could,” “would,” “predict,” “potential,” “continue,” “expect,” “anticipate,” “future,” “intend,” “plan,” “believe,” “estimate,” and similar expressions, as well as statements in future tense, identify forward-looking statements. However, not all forward-looking statements contain these identifying words.

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and potentially inaccurate assumptions. The following important factors could cause actual results to differ materially from those in the forward-looking statements: the potential global impacts of the COVID-19 pandemic; our exposure to cancellations of government contracts due to appropriation clauses, exercise of a cancellation clause, or non-exercise of contractually optional periods; our ability to design, introduce and sell new products or features; our ability to defend against litigation and protect our intellectual property, and the resulting costs of this activity; our ability to manage our supply chain and avoid production delays, shortages, and impacts to expected gross margins; the impact of stock compensation expense, impairment expense, and income tax expense on our financial results; customer purchase behavior, including adoption of our software as a service delivery model; negative media publicity regarding our products; the impact of product mix on projected gross margins; defects in our products; changes in the costs of product components and labor; loss of customer data, a breach of security, or an extended outage, including our reliance on third party cloud-based storage providers; exposure to international operational risks; delayed cash collections and possible credit losses due to our subscription model; changes in government regulations in the U.S. and in foreign markets, especially related to the classification of our product by the United States Bureau of Alcohol, Tobacco, Firearms and Explosives and to evolving regulations surrounding privacy and data protection; our ability to integrate acquired businesses; our ability to attract and retain key personnel; and counter-party risks relating to cash balances held in excess of FDIC insurance limits. Many events beyond our control may determine whether results we anticipate will be achieved. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could differ materially from past results and those anticipated, estimated or projected. You should bear this in mind as you consider forward-looking statements. The Annual Report on Form 10-K that we filed with the Securities and Exchange Commission ("SEC") on February 28, 2020 and this Quarterly Report on Form 10-Q list various important factors that could cause actual results to differ materially from expected and historical results. These factors are intended as cautionary statements for investors within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act. Readers can find them under the heading “Risk Factors” in the Report on Form 10-K and in this Report on Form 10-Q, and investors should refer to them. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.

Except as required by law, we undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any further disclosures we make on related subjects in our Form 10-Q, 8-K and 10-K reports to the SEC. Our filings with the SEC may be accessed at the SEC’s web site at www.sec.gov.

1. Organization and Summary of Significant Accounting Policies

Axon Enterprise, Inc. (“Axon,” the “Company,” "we," or "us") is a market-leading provider of law enforcement technology solutions. Our core mission is to protect life. We fulfill that mission through developing hardware and software products that advance the long term objectives of a) obsoleting the bullet, b) reducing social conflict, and c) enabling a fair and effective justice system.

Our headquarters in Scottsdale, Arizona houses our executive management, sales, marketing, certain engineering, manufacturing, and other administrative support functions. We also have a software engineering development center located in Seattle, Washington, and subsidiaries located in Australia, Canada, Finland, Hong Kong, Germany, India, Italy, the Netherlands, the United Kingdom, and Vietnam.

The accompanying unaudited condensed consolidated financial statements include the accounts of Axon Enterprise, Inc. and our wholly owned subsidiaries. All material intercompany accounts, transactions, and profits have been eliminated.

Basis of Presentation and Use of Estimates

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information related to our organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) has been condensed or omitted. The accounting policies followed in the preparation of these unaudited condensed consolidated financial statements are consistent with those followed in our annual consolidated financial statements for the year ended December 31, 2019, as filed on Form 10-K, with the exception of our adoption of certain accounting pronouncements which we describe below. In the opinion of management, these unaudited condensed consolidated financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary to fairly state our financial position, results of operations and cash flows for the periods presented and the presentations and disclosures herein are adequate when read in conjunction with our Form 10-K for the year ended December 31, 2019. The results of operations for the three months and six months ended June 30, 2020 and 2019 are not necessarily indicative of the results to be expected for the full year (or any other period). Significant estimates and assumptions in these unaudited condensed consolidated financial statements include:

● product warranty reserves,

● inventory valuation,

● revenue recognition,

● expected credit loss reserves,

● valuation of goodwill, intangible and long-lived assets,

● recognition, measurement and valuation of current and deferred income taxes,

● stock-based compensation,

● recognition and measurement of lease liabilities,

● recognition and measurement of contingencies and accrued litigation expense, and

● fair values of identified tangible and intangible assets acquired and liabilities assumed in business combinations.

Actual results could differ materially from those estimates.

Segment Information

Our operations are comprised of two reportable segments: the manufacture and sale of conducted electrical devices ("CEDs"), batteries, accessories, extended warranties and other products and services (the “TASER” segment);

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

and the development, manufacture, and sale of software and sensors, which includes the sale of devices, wearables, applications, cloud and mobile products, and services (collectively, the “Software and Sensors” segment). In both segments, we report sales of products and services. Service revenue in both segments includes sales related to Axon Evidence. In the Software and Sensors segment, service revenue also includes other recurring cloud-hosted software revenue and related professional services. Collectively, this revenue is sometimes referred to as "Axon Cloud revenue."  

Reportable segments are determined based on discrete financial information reviewed by our Chief Executive Officer who is our chief operating decision maker ("CODM"). We organize and review operations based on products and services, and currently there are no operating segments that are aggregated. We perform an analysis of our reportable segments at least annually. Additional information related to our business segments is summarized in Note 14.

Geographic Information and Major Customers / Suppliers

For the three and six months ended June 30, 2020 and 2019, no individual country outside the U.S. represented more than 10% of total net sales. Individual sales transactions in the international market are generally larger and occur more intermittently than in the domestic market due to the profile of our customers. For the three and six months ended June 30, 2020 and 2019, no customer represented more than 10% of total net sales. At June 30, 2020 and December 31, 2019, no customer represented more than 10% of the aggregate balance of accounts and notes receivable and contract assets.

We currently purchase both off the shelf and custom components, including, but not limited to, finished circuit boards, injection-molded plastic components, small machined parts, custom cartridge components, electronic components, and off the shelf sub-assemblies from suppliers located in the U.S., Canada, China, Israel, Mexico, Republic of Korea, Sri Lanka, and Taiwan. Although we currently obtain many of these components from single source suppliers, we own the injection molded component tooling, most of the designs, and the test fixtures used in their production for all custom components. As a result, we believe we could obtain alternative suppliers in most cases without incurring significant production delays. We also strategically hold safety stock levels on custom components to further reduce this risk. For off the shelf components, we believe that in most cases there are readily available alternative suppliers who can consistently meet our needs for these components. We acquire most of our components on a purchase order basis and do not have any significant long-term contracts with component suppliers.

Income per Common Share

Basic income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the periods presented. Diluted income per share reflects the potential dilution from outstanding stock options and unvested restricted stock units. The calculation of the weighted average number of shares outstanding and earnings per share are as follows (in thousands except per share data):

Standard Warranties

We warranty our CEDs, Axon cameras and certain related accessories from manufacturing defects on a limited basis for a period of one year after purchase and, thereafter, will repair or replace any defective unit for a fee. Estimated costs for the standard warranty are charged to cost of products sold when revenue is recorded for the related product. Future warranty costs are estimated based on historical data related to warranty claims and this rate is applied to current product sales. Historically, reserve amounts have been increased if management becomes aware of a component failure or other issue that could result in larger than anticipated warranty claims from customers. The warranty reserve is reviewed quarterly to verify that it sufficiently reflects the remaining warranty obligations based on the anticipated expenditures over the balance of the warranty obligation period, and adjustments are made when actual warranty claim experience differs from estimates. The warranty reserve is included in accrued liabilities on the accompanying condensed consolidated balance sheets.

Changes in our estimated product warranty liabilities were as follows (in thousands):

Fair Value Measurements and Financial Instruments

We use the fair value framework that prioritizes the inputs to valuation techniques for measuring financial assets and liabilities measured on a recurring basis and for non-financial assets and liabilities when these items are re-measured. Fair value is considered to be the exchange price in an orderly transaction between market participants, to sell an asset or transfer a liability at the measurement date. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

● Level 1 – Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

● Level 2 – Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.

● Level 3 – Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect our own assumptions about inputs that market participants would use in pricing an asset or liability.

We have cash equivalents and investments, which at June 30, 2020 and December 31, 2019 were comprised of money market funds, certificates of deposit, commercial paper, corporate bonds, corporate notes, municipal bonds, U.S. Government agency bonds, U.S. Treasury bills, U.S. Treasury inflation-protected securities, and U.S. Treasury repurchase agreements. See additional disclosure regarding the fair value of our cash equivalents and investments in Note 3. Included in the balance of other assets as of June 30, 2020 and December 31, 2019 was $4.0 million and $4.2 million, respectively, related to corporate-owned life insurance policies which are used to fund our deferred compensation plan. We determine the fair value of insurance contracts by obtaining the cash surrender value of the contracts from the issuer, a Level 2 valuation technique. In March 2020, we made an investment of $4.7 million in preferred stock and recorded preferred stock warrants at a fair value of $2.6 million, which is also included in the balance of other assets as of June 30, 2020. The estimated fair value of the investments was determined based on Level 3 inputs. As of June 30, 2020, management estimated that the fair value of the investment equaled its carrying value.

Our financial instruments also include accounts and notes receivable, accounts payable and accrued liabilities. Due to the short-term nature of these instruments, their fair values approximate their carrying values on the balance sheet.

Restricted Cash

Restricted cash balances as of June 30, 2020 and December 31, 2019 included $0.1 million primarily related to funds held in an international bank account for a country in which we are required to maintain a minimum balance to operate. Approximately half of the balance was included in prepaid expenses and other current assets on our condensed consolidated balance sheets, with the remainder included in other assets.

Valuation of Goodwill, Intangibles and Long-lived Assets

We evaluate whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets and identifiable intangible assets, excluding goodwill and intangible assets with indefinite useful lives, may warrant revision or that the remaining balance of these assets may not be recoverable. Such circumstances could include, but are not limited to, a change in the product mix, a change in the way products are created, produced or delivered, or a significant change in the way products are branded and marketed. In performing the review for recoverability, we estimate the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. The amount of the impairment loss, if impairment exists, is calculated based on the excess of the carrying amounts of the assets over their estimated fair value computed using discounted cash flows.

We do not amortize goodwill and intangible assets with indefinite useful lives; rather such assets are required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired. We perform our annual goodwill and intangible asset impairment tests in the fourth quarter of each year.

Recently Issued Accounting Guidance

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial

AXON ENTERPRISE, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Instruments. ASU 2016-13 includes an impairment model (known as the current expected credit loss model) on financial instruments and other commitments that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The use of forecasted information is intended to incorporate more timely information in the estimate of expected credit loss. This ASU also requires enhanced disclosures relating to significant estimates and judgments used in estimating credit losses, as well as credit quality. Upon adoption, we recorded a noncash cumulative effect adjustment to retained earnings of $0.6 million, net of $0.2 million of income taxes, on the opening consolidated balance sheet as of January 1, 2020,  reflecting an overall increase to the allowance for expected credit losses. See Notes 3 and 4 for further disclosures related to Topic 326.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 eliminates, adds and modifies certain disclosure requirements for fair value measurements. The amendments apply to the disclosures of changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Adoption of this ASU on January 1, 2020 did not have a material impact on our consolidated financial statements.

Effective the first quarter of 2021:

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in the ASU are effective for fiscal years beginning after December 15, 2020, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. Adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

In January 2020, the FASB issued ASU No. 2020-01, Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (a Consensus of the Emerging Issues Task Force). The guidance clarifies the interaction between ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities and the ASU on equity method investments. ASU 2016-01 provides companies with an alternative to measure certain equity securities without a readily determinable fair value at cost, minus impairment, if any, unless an observable transaction for an identical or similar security occurs. ASU 2020-01 clarifies that for purposes of applying the Topic 321 measurement alternative, an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting under Topic 323, immediately before applying or upon discontinuing the equity method. In addition, the new ASU provides direction that a company should not consider whether the underlying securities would be accounted for under the equity method or the fair value option when it is determining the accounting for certain forward contracts and purchased options, upon either settlement or exercise. The amendments in this update become effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, and the amendments are to be applied prospectively. Adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

Reclassification of Prior Year Presentation

Certain prior year amounts, including the long-term portion of contract assets, have been reclassified for consistency with the current year presentation. These reclassifications are not material and had no effect on the reported results of operations.

Remaining Performance Obligations

As of June 30, 2020, we had approximately $1.34 billion of remaining performance obligations, which included both recognized contract liabilities as well as amounts that will be invoiced and recognized in future periods. The remaining performance obligations are limited only to arrangements that meet the definition of a contract under Topic 606 as of June 30, 2020. We expect to recognize between 20% - 25% of this balance over the next twelve months, and generally expect the remainder to be recognized over the following five to seven years, subject to risks related to delayed deployments, budget appropriation or other contract cancellation clauses.

As of June 30, 2020, the balances reflected above were offset by a net payable of $10.4 million related to unsettled investment purchases, which was settled in early July. We believe unrealized losses on our investments are due to interest rate fluctuations.

We adopted Topic 326 on January 1, 2020, and applied the credit loss guidance related to held-to-maturity securities prospectively. Because we do not have any history of losses for our held-to-maturity investments, our expected loss allowance methodology for held-to-maturity investments is developed using published or estimated credit default rates for similar investments and current and future economic and market conditions. At both January 1 and June 30, 2020, our credit loss reserve for held-to-maturity investments was approximately $0.1 million. During the three and six months ended June 30, 2020, we increased the frequency of review for our investment portfolio in order to more closely monitor potential impacts of the novel coronavirus ("COVID-19”) pandemic.

4. Expected Credit Losses

We are exposed to credit losses primarily through sales of products and services. Our expected loss allowance methodology for accounts receivable, notes receivable, and contract assets is developed using historical collection experience, published or estimated credit default rates for entities that represent our customer base, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. Our monitoring activities include account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible.

We considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and recorded additional credit loss expense of approximately $0.8 million during the six months ended June 30, 2020.

We review receivables for U.S. and international customers separately to better reflect different published credit default rates and economic and market conditions.

(1) Represents the incremental costs of obtaining contracts with customers, which consist primarily of sales commissions. These costs are ascribed to or allocated to the underlying performance obligations in the contracts and amortized consistent with the recognition timing of the revenue for the underlying performance obligations.

(2) In March 2020, we made an investment in and entered into a commercial partnership agreement with Flock Group Inc., a provider of advanced security for neighborhoods and law enforcement. Our $4.7 million investment resulted in our ownership of approximately 5% of the outstanding equity interests of this company. We account for this investment under the ASC 321 measurement alternative for equity securities without readily determinable fair values, as there are no quoted market prices for the investment. The investment is measured at cost less impairment, adjusted for observable price changes and is assessed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. As of June 30, 2020, no impairment was recorded for the investment.

(3) In conjunction with the equity investment in and commercial partnership with Flock Group, Inc., we have the ability to commit additional capital over time through warrants where the exercisability and exercise prices are conditional on the achievement of certain partnership performance metrics. The fair value of the preferred stock warrants was estimated at $2.6 million using Monte Carlo simulation.

9. Income Taxes

We file income tax returns for federal purposes and in many states, as well as in multiple foreign jurisdictions. Our tax filings remain subject to examination by applicable tax authorities for a certain length of time, generally three to four years, following the tax year to which these filings relate. In July 2020, we received notification from the Internal Revenue Service that the audit of  our U.S. federal income tax return for fiscal year 2016 was completed. During the second quarter we began an audit with the State of California for our fiscal year 2016 and 2017 state tax returns, which is currently ongoing. Additionally, we have been notified that an audit will commence for Axon Public Safety Southeast Asia LLC, our entity in Vietnam. The tax period has not yet been defined.

On March 27, 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The CARES Act is an emergency economic stimulus package in response to the coronavirus outbreak which, among other things, contains numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for years ending before the date of enactment. We are continuing to evaluate the implications of the CARES Act, but its impact on our financial statements and related disclosures is not expected to be material.

In April 2020, recent interpretations of a German law relating to withholding taxes on intellectual property rights emerged.  We have evaluated this law and do not expect a material impact to our financial position or results of operations.

Deferred Tax Assets

Net deferred income tax assets at June 30, 2020, primarily include R&D tax credits, stock-based compensation expense, deferred revenue, accruals and reserves, and net operating losses, partially offset by accelerated depreciation expense and valuation allowance reserve. Our total net deferred tax assets at June 30, 2020 were $33.7 million.

In preparing our condensed consolidated financial statements, management assesses the likelihood that its deferred tax assets will be realized from future taxable income. In evaluating our ability to recover our deferred income tax assets, management considers all available positive and negative evidence, including our operating results, ongoing tax planning and forecasts of future taxable income on a jurisdiction by jurisdiction basis. A valuation allowance is established if it is determined that it is more likely than not that some portion or all of the net deferred tax assets will not be realized. Management exercises significant judgment in determining our provisions for income taxes, our deferred tax assets and liabilities, and our future taxable income for purposes of assessing our ability to utilize any future tax benefit from our deferred tax assets.

As of June 30, 2020, we continue to demonstrate three-year cumulative pre-tax income in the U.S. federal and state tax jurisdictions; however, we have Arizona R&D Tax Credits expiring unutilized each year. Therefore, management has concluded that it is more likely than not that our Arizona R&D deferred tax asset will not be realized.

As of June 30, 2020, we have cumulative pre-tax losses in the U.K. and Canada, which limits the ability to consider other subjective evidence, such as projections for future growth. On the basis of this evaluation, a full valuation allowance has been recorded for these jurisdictions. The amount of the deferred tax asset considered realizable, however, could be adjusted in future periods if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as projections for growth.

In Australia, we have determined that sufficient deferred tax liabilities will reverse in order to realize all assets except one long-lived intangible where there is not an expectation that the asset may be realized. Therefore, we have recorded a partial valuation allowance for Australia.

We complete R&D tax credit studies for each year that an R&D tax credit is claimed for federal, Arizona, and California income tax purposes. Management has made the determination that it is more likely than not that the full benefit of the R&D tax credit will not be sustained on examination and recorded a liability for unrecognized tax benefits of $6.9 million as of June 30, 2020. Should the unrecognized benefit of $6.9 million be recognized, our effective tax rate would be favorably impacted. Approximately $2.7 million of the unrecognized tax benefit associated with R&D credits has been netted against the R&D deferred tax asset.

Effective Tax Rate

Our overall effective tax rate for the six months ended June 30, 2020, after discrete period adjustments, was  (123.8%). Before discrete adjustments, the tax rate was (173.8%), which differs from the federal statutory rate, primarily due to the impact of the executive compensation limitation under Internal Revenue Code ("IRC") Section 162(m) on a projected pre-tax loss for the year. The effective tax rate was favorably impacted by a $5.9 million discrete tax benefit primarily associated with windfalls related to stock-based compensation for restricted stock units (“RSUs”) that vested or stock options that were exercised during the six months ended June 30, 2020.

10. Stockholders’ Equity

Follow-on offering

In June 2020, we sold 3,450,000 shares of our common stock, which included 450,000 shares pursuant to the full exercise of the underwriters' option to purchase additional shares, in an underwritten public offering at a price of $92.00 per

share, which resulted in gross proceeds of $317.4 million. Net proceeds to us after deducting fees, commissions, and other expenses related to the offering were $306.8 million.

Performance-based stock awards

We have issued performance-based stock options and performance-based RSUs, the vesting of which is generally contingent upon the achievement of certain performance criteria related to our operating performance, as well as successful and timely development and market acceptance of future product introductions. In addition, certain of the performance RSUs have additional service requirements subsequent to the achievement of the performance criteria. Compensation expense is recognized over the requisite service period, which is defined as the longest explicit, implicit or derived service period based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date. For both service-based and performance-based RSUs, we account for forfeitures as they occur as a reduction to stock-based compensation expense and additional paid-in-capital.

For performance-based options with a vesting schedule based entirely on the attainment of both performance and market conditions, stock-based compensation expense is recognized for each pair of performance and market conditions over the longer of the expected achievement period of the performance and market conditions, beginning at the point in time that the relevant performance condition is considered probable of achievement. The fair value of such awards is estimated on the grant date using Monte Carlo simulations.

CEO Performance Award

On May 24, 2018, our stockholders approved the Board of Directors’ grant of 6,365,856 stock option awards to Patrick W. Smith, our CEO (the “CEO Performance Award”). The CEO Performance Award consists of 12 vesting tranches with a vesting schedule based entirely on the attainment of both operational goals (performance conditions) and market capitalization goals (market conditions), assuming continued employment either as the CEO or as both Executive Chairman and Chief Product Officer and service through each vesting date. Each of the 12 vesting tranches of the CEO Performance Award have a 10-year contractual term and will vest upon certification by the Board of Directors that both (i) the market capitalization goal for such tranche, which begins at $2.5 billion for the first tranche and increases by increments of $1.0 billion thereafter, and (ii) any one of the following eight operational goals focused on revenue or eight operational goals focused on Adjusted EBITDA have been met for the previous four consecutive fiscal quarters. Adjusted EBITDA for purposes of the CEO Performance Award ("Adjusted EBITDA (CEO Performance Award)") is defined as net income (loss) attributable to common stockholders before interest expense,  investment interest income, provision (benefit) for income taxes, depreciation and amortization, and stock-based compensation expense.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

As of June 30, 2020, the following operational goals were considered probable of achievement:

● Total revenue of $710.1 million, $860.1 million, and $1,010.1 million; and

● Adjusted EBITDA (CEO Performance Award) of $125.0 million, $155.0 million, $175.0 million, $190.0 million, $200.0 million, $210.0 million, $220.0 million, and $230.0 million.

The first three market capitalization goals have been achieved as of June 30, 2020. However, none of the stock options granted under the CEO Performance Award have vested thus far as the operational goals have not yet been achieved as of June 30, 2020. As there are eleven operational goals considered probable of achievement, we recorded stock-based compensation expense of $60.5 million related to the CEO Performance Award from the Grant Date through June 30, 2020. The number of stock options that would vest related to the eleven tranches is approximately 5.8 million shares.

As of June 30, 2020, we had $167.9 million of total unrecognized stock-based compensation expense for the performance goals that were considered probable of achievement, which will be recognized over a weighted-average period of 5.31 years. As of June 30, 2020, we had unrecognized stock-based compensation expense of $17.6 million for the performance goals that were considered not probable of achievement.

eXponential Stock Performance Plan

On February 12, 2019, our shareholders approved the 2019 Stock Incentive Plan (the “2019 Plan”), which was adopted by the Board of Directors to reserve a sufficient number of shares to facilitate our eXponential Stock Performance Plan (“XSPP”) and grants of eXponential Stock Units (“XSUs”) under the plan. Initial awards under the plan were granted in January 2019, with additional employee awards granted since that date. During the three and six months ended June 30, 2020, we granted an additional 0.1 million and 0.2 million XSUs, respectively.

The XSUs are grants of RSUs, each with a term of approximately nine years, that vest in 12 equal tranches. Each of the 12 tranches will vest upon certification by the Compensation Committee of the Board of Directors that both (i) the market capitalization goal for such tranche, which begins at $2.5 billion for the first tranche and increases by increments of $1.0 billion thereafter, and (ii) any one of eight operational goals focused on revenue or eight operational goals focused on Adjusted EBITDA (CEO Performance Award) have been met for the previous four consecutive fiscal quarters.

The XSPP contains an anti-dilution provision incorporated into the plan based on shareholder feedback, which affects the calculation of the market capitalization goals in the plan. The plan defines a maximum number of shares outstanding that may be used in the calculation of the market capitalization goals (the “XSU Maximum”). If the actual number of shares outstanding exceeds the XSU Maximum guardrail, then the lower pre-defined number of shares in the XSU Maximum, rather than the higher actual number of shares outstanding, is used to calculate market capitalization for the determination of the market capitalization goals in the XSPP, which, together with the operational goals, determines whether XSUs vest for participating employees.

The XSU Maximum is defined as the actual number of shares outstanding on the original XSU grant date of January 2, 2019, increased by a 3% annual rate over the term of the XSPP and by shares issued upon the exercise of CEO Performance Award options. The XSU Maximum is also adjusted for acquisitions, spin-offs or other changes in the number of outstanding shares of common stock, if such changes have a corresponding adjustment on the market capitalization goals.

New shares issued for any other reasons, including shares issued upon vesting of XSUs, RSUs, and PSUs as well as shares issued to raise capital through equity issuances or in other transactions, do not increase the XSU Maximum.

19

AXON ENTERPRISE, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

The market capitalization and operational goals are identical to the CEO Performance Award, but a different number of shares is used to calculate the market capitalization goals if shares outstanding exceed the XSU Maximum. Additionally, because the grant date is different than that of the CEO Performance Award, the measurement period for market capitalization is not identical.

As of June 30, 2020, actual shares outstanding exceeded the XSU Maximum as a result of the common stock offering completed in June 2020. Accordingly, market capitalization as calculated for the purposes of achieving additional goals uses the lower XSU Maximum share amount rather than actual shares outstanding. The first three market capitalization goals have been achieved as of June 30, 2020. However, none of the XSU tranches have vested thus far as the operational goals have not yet been achieved as of June 30, 2020. As there are eleven operational goals considered probable of achievement, we recorded stock-based compensation expense of $33.8 million related to the XSU awards from their respective grant dates through June 30, 2020. The number of XSU awards that would vest related to the eleven tranches is approximately 5.0 million shares.

As of June 30, 2020, we had $148.1 million of total unrecognized stock-based compensation expense for the performance goals that were considered probable of achievement, which will be recognized over a weighted-average period of 5.12 years. As of June 30, 2020, we had unrecognized stock-based compensation expense of $11.4 million for the performance goals that were considered not probable of achievement.

Forfeited	(68)		46.85
Units outstanding, end of period	1,067		52.93	$	104,743

Aggregate intrinsic value represents our closing stock price on the last trading day of the period, which was $98.13 per share, multiplied by the number of RSUs outstanding. As of June 30, 2020, there was $42.4 million in unrecognized compensation costs related to RSUs under our stock plans for shares that are expected to vest. We expect to recognize the cost related to the RSUs over a weighted average period of 2.04 years. RSUs are released when vesting requirements are met.

Certain RSUs that vested in the six months ended June 30, 2020 were net-share settled such that we withheld shares to cover the employees’ tax obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. Total shares withheld related to RSUs were approximately 0.1 million and had a value of $4.6 million on their respective vesting dates as determined by the closing stock price on such dates. Payments for the employees’ tax obligations are reflected as a financing activity within the condensed consolidated statements of cash flows. We record a liability for the tax withholding to be paid by us as a reduction to additional paid-in capital.

Forfeited	(303)		36.10
Units outstanding, end of period	5,801		35.26	$	569,207

Aggregate intrinsic value represents our closing stock price on the last trading day of the period, which was $98.13 per share, multiplied by the number of PSUs outstanding. As of June 30, 2020, there was $152.6 million in unrecognized compensation costs related to PSUs under our stock plans for shares that are expected to vest. We expect to recognize the cost related to the PSUs over a weighted average period of 5.03 years. PSUs are released when vesting requirements are met.

As of June 30, 2020, the performance criteria had been met for approximately 0.1 million of the 5.8 million PSUs outstanding. Certain of the PSUs outstanding as of June 30, 2020 can vest with a range of shares earned being between 0% and 200% of the targeted shares granted, depending on the final achievement of pre-determined performance criteria as of the vesting date. The amount of PSUs included in the table above related to such grants is the target level. The maximum additional number of PSUs that could be earned is 0.2 million, which are not included in the table above.

Certain PSUs that vested in the six months ended June 30, 2020 were net-share settled such that we withheld shares to cover the employees’ tax obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. Total shares withheld related to PSUs were approximately 16 thousand and had a value of $1.2 million on their respective vesting dates as determined by the closing stock price on such dates. Payments for the employees’ tax obligations are reflected as a financing activity within the condensed consolidated statements of cash flows.

Stock Incentive Plan

In February 2019, our shareholders approved the 2019 Plan authorizing an additional 6.0 million shares, plus remaining available shares under prior plans, for issuance under the new plan. Combined with the legacy stock incentive plans, there are 2.0 million shares available for grant as of June 30, 2020.

Stock Repurchase Plan

In February 2016, our Board of Directors authorized a stock repurchase program to acquire up to $50.0 million of our outstanding common stock subject to stock market conditions and corporate considerations. During the six months ended June 30, 2020 and 2019, no common shares were purchased under the program. As of June 30, 2020, $16.3 million remains available under the plan for future purchases. Any future purchases will be discretionary.

11. Line of Credit

We have a $50.0 million unsecured revolving line of credit with a domestic bank, of which $10.0 million is available for letters of credit. The credit agreement matures on December 31, 2021 and has an accordion feature which allows for an increase in the total line of credit up to $100.0 million, subject to certain conditions, including the availability of additional bank commitments.

At June 30, 2020 and December 31, 2019, there were no borrowings under the line. Under the terms of the line of credit, available borrowings are reduced by outstanding letters of credit. As of June 30, 2020, we had letters of credit outstanding of approximately $6.1 million under the facility and available borrowing of $43.9 million, excluding amounts available under the accordion feature. Advances under the line of credit bear interest at LIBOR plus 1.0 to 1.5% per year determined in accordance with a pricing grid based on our funded debt to earnings before interest, taxes, depreciation and amortization ("EBITDA") ratio.

We are required to comply with a maximum funded debt to EBITDA ratio of no greater than 2.50 to 1.00 based upon a trailing four fiscal quarter period. At June 30, 2020, our funded debt to EBITDA ratio was 0.0001 to 1.00.

As a manufacturer of weapons and other law enforcement tools used in high-risk field environments, we are often the subject of products liability litigation concerning the use of our products.  We are currently named as a defendant in eight lawsuits in which the plaintiffs allege either wrongful death or personal injury in situations in which a TASER CED was used by law enforcement officers in connection with arrests or training. While the facts vary from case to case, these product liability claims typically allege defective product design, manufacturing, and/or failure to warn. They seek compensatory and sometimes punitive damages, often in unspecified amounts.

We continue to aggressively defend all product litigation. As a general rule, it is our policy not to settle suspect injury or death cases. Exceptions are sometimes made where the settlement is strategically beneficial to us. Due to the confidential nature of our litigation strategy and the confidentiality agreements that are executed in the event of a settlement, we do not identify or comment on specific settlements by case or amount. Based on current information, we do not believe that the outcome of any such legal proceeding will have a material effect on our financial position, results of operations, or cash flows. We are self-insured for the first $5.0 million of any product claim made after 2014. No judgment or settlement has ever exceeded this amount in any products case. We continue to maintain product liability insurance coverage, including an insurance policy fronting arrangement, above our self-insured retention with various limits depending on the policy period.

Other Litigation

We are a defendant in a consumer class action lawsuit filed in the District of Nevada on April 9, 2019 by Douglas Richey (“Richey”). The case alleges the TASER Pulse, X2 and X26P CEDs have a faulty safety switch based on Richey’s Pulse allegedly discharging inside its neoprene case in a jacket pocket without injury. Any such discharge was likely due to static electricity, as disclosed in our consumer warnings. The nationwide class allegations have been withdrawn and any applicable class is limited to California purchasers. We are vigorously defending this suit and the propriety of any class certification.

The litigation information in this note is current through the date of these financial statements.

U.S. Federal Trade Commission Litigation

The U.S. Federal Trade Commission (“FTC”) filed an enforcement action on January 3, 2020 regarding Axon’s May 2018 acquisition of Vievu LLC from Safariland LLC. The FTC alleges the merger was anticompetitive and adversely affected the body worn camera (“BWC”) and digital evidence management systems (“DEMS”) market for “large metropolitan police departments.” The stay of the administrative proceedings due to the COVID-19 pandemic lifted July 7 and discovery is underway.  The hearing has been reset for October 13, 2020. If successful, the FTC may require us to divest Vievu and other assets or take other remedial measures, any of which could be material to Axon. We are vigorously defending the matter. At this time, we cannot predict the eventual scope, duration, or outcome of this request and accordingly we have not recorded any liability in the accompanying condensed consolidated financial statements.

Also, on January 3, 2020, we sued the FTC in the U.S. District of Arizona for declaratory and injunctive relief alleging the FTC’s structure and administrative processes violate Article II of the U.S. Constitution and our Fifth Amendment rights to due process and equal protection. On April 8, 2020, the district court dismissed the action, without prejudice, for lack of jurisdiction, requiring Axon to first bring its constitutional claims in the administrative case. Axon has appealed that ruling to the Ninth Circuit (No. 20-15662), which granted expedited consideration and heard oral argument on July 17.  The matter is now under advisement.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

In parallel to these matters, we are evaluating strategic alternatives to litigation, which we might pursue if determined to be in the best interests of shareholders and customers. This could include a divestiture of the Vievu entity and/or related assets and the licensure of certain intellectual and other intangible property. While we continue to believe the acquisition of Vievu in 2018 was lawful and a benefit to Vievu's customers, the cost, risk and distraction of protracted litigation merit consideration of settlement if achievable on terms agreeable to the FTC and us.

General

From time to time, we are notified that we may be a party to a lawsuit or that a claim is being made against us. It is our policy to not disclose the specifics of any claim or threatened lawsuit until the summons and complaint are actually served on us. After carefully assessing the claim, and assuming we determine that we are not at fault or we disagree with the damages or relief demanded, we vigorously defend any lawsuit filed against us. We record a liability when losses are deemed probable and reasonably estimable. When losses are deemed reasonably possible but not probable, we determine whether it is possible to provide an estimate of the amount of the loss or range of possible losses for the claim, if material for disclosure. In evaluating matters for accrual and disclosure purposes, we take into consideration factors such as our historical experience with matters of a similar nature, the specific facts and circumstances asserted, the likelihood of our prevailing, the availability of insurance, and the severity of any potential loss. We reevaluate and update accruals as matters progress over time.

Based on our assessment of outstanding litigation and claims as of June 30, 2020, we have determined that it is not reasonably possible that these lawsuits will individually, or in the aggregate, materially affect our results of operations, financial condition or cash flows. However, the outcome of any litigation is inherently uncertain and there can be no assurance that any expense, liability or damages that may ultimately result from the resolution of these matters will be covered by our insurance or will not be in excess of amounts recognized or provided by insurance coverage and will not have a material adverse effect on our operating results, financial condition or cash flows.

Off-Balance Sheet Arrangements

Under certain circumstances, we use letters of credit and surety bonds to guarantee our performance under various contracts, principally in connection with the installation and integration of Axon cameras and related technologies. Certain of our letters of credit and surety bonds have stated expiration dates with others being released as the contractual performance terms are completed. At June 30, 2020, we had outstanding letters of credit of $6.1 million that are expected to expire in June 2021 and September 2021. We also had outstanding letters of credit and bank guarantees of $1.9 million that do not draw against our credit facility. The outstanding letters of credit are expected to expire in June 2021. Additionally, we had $24.0 million of outstanding surety bonds at June 30, 2020, with $0.5 million expiring in 2020, $2.3 million expiring in 2021, $3.2 million expiring in 2022, $7.5 million expiring in 2023 and the remaining $10.5 million expiring in 2024.

13. Employee Benefit Plans

We have a defined contribution 401(k) plan for eligible employees, which is qualified under Sections 401(a) and 401(k) of the Internal Revenue Code of 1986, as amended. Employees are entitled to make tax-deferred contributions of up to the maximum amount allowed by law of their eligible compensation.

We also have a non-qualified deferred compensation plan for certain executives, employees and non-employee directors through which participants may elect to postpone the receipt and taxation of a portion of their compensation, including stock-based compensation, received from us. The non-qualified deferred compensation plan allows eligible participants to defer up to 80% of their base salary and up to 100% of other types of compensation. The plan also allows for matching and discretionary employer contributions. Employee deferrals are deemed 100% vested upon contribution. Distributions from the plan are made upon retirement, death, separation of service, specified date or upon the occurrence of an unforeseeable emergency. Distributions can be paid in a variety of forms from lump sum to installments over a period

of years. Participants in the plan are entitled to select from a wide variety of investments available under the plan and are allocated gains or losses based upon the performance of the investments selected by the participant. All gains or losses are allocated fully to plan participants and we do not guarantee a rate of return on deferred balances. Assets related to this plan consist of corporate-owned life insurance contracts and are included in other assets in the condensed consolidated balance sheets; see Note 7 for balances. Participants have no rights or claims with respect to any plan assets and any such assets are subject to the claims of our general creditors.

Contributions to the plans are made by both the employee and us. Our contributions to the 401(k) plan are based on the level of employee contributions and are immediately vested. Future matching contributions to the plans are at our sole discretion.

We also sponsor defined contribution plans in Australia, Finland, and the United Kingdom.

Our matching contributions for all defined contribution plans were $1.3 million and $1.1 million for the three months ended June 30, 2020 and 2019, respectively and $2.8 million and $2.5 million for the six months ended June 30, 2020 and 2019, respectively.

14. Segment Data

Our operations are comprised of two reportable segments: the manufacture and sale of CEDs, batteries, accessories, extended warranties and other products and services (the “TASER” segment); and the software and sensors business, which includes the sale of devices, wearables, applications, cloud and mobile products, and services (collectively, the “Software and Sensors” segment). In both segments, we report sales of products and services. Service revenue in both segments includes sales related to Axon Evidence. In the Software and Sensors segment, service revenue also includes other recurring cloud-hosted software revenue and related professional services. Collectively, this revenue is sometimes referred to as "Axon Cloud revenue." Our Chief Executive Officer, who is the CODM, is not provided asset information or sales, general, and administrative expense by segment.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition as of June 30, 2020, and results of operations for the three and six months ended June 30, 2020 and 2019, should be read in conjunction with the condensed consolidated financial statements and related notes included in this Report on Form 10-Q and the audited consolidated financial statements in our 2019 Annual Report on Form 10-K filed with the SEC on February 28, 2020. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in such forward-looking statements as a result of certain factors, including but not limited to those described under “Risk Factors” in our 2019 Annual Report on Form 10-K. See also "Special Note Regarding Forward-Looking Statements" on page ii of this Report on Form 10-Q.

Overview

Axon is a global network of devices, apps, training and people that helps public safety personnel become smarter and safer. Our technologies give law enforcement the confidence, focus and time they need to protect their communities. Our products impact every aspect of an officer's day-to-day experience. Our core mission is to protect life. We fulfill that mission through developing hardware and software products that advance our long term vision of a) obsoleting the bullet, b) reducing social conflict, and c) enabling a fair and effective justice system.

Our revenues for the three months ended June 30, 2020 were $141.3 million, an increase of $28.9 million, or 25.7%, from the comparable period in the prior year. We had a loss from operations of $13.7 million compared to $1.3 million for the same period in the prior year. Gross margin improved compared to the three months ended June 30, 2019 as a result of product mix, with improvement partially offset by additional expenses related to the COVID-19 pandemic. Increased operating expenses to support continued and future growth also contributed to the decline in operating results. Expenses for the quarter ended June 30, 2020 also reflected an increase of $24.1 million in stock-based compensation expense related to the CEO Performance Award and XSPP. An increase in litigation costs and in charitable contributions also contributed to the higher selling, general and administrative expense. For the three months ended June 30, 2020, we recorded a net loss of $30.8 million, which reflected income tax expense of $18.7 million, compared to net income of $0.7 million for the comparable period in the prior year.

Our revenues for the six months ended June 30, 2020 were $288.4 million, an increase of $60.2 million, or 26.4%, from the comparable period in the prior year. We had a loss from operations of $14.5 million compared to income from operations of $1.4 million for the same period in the prior year. Gross margin improved compared to the six months ended June 30, 2019 as a result of product mix, with improvement partially offset by additional expenses related to the COVID-19 pandemic. Increased operating expenses to support continued and future growth also contributed to the decline in operating results. Expenses for the six months ended June 30, 2020 also reflected an increase of $52.1 million in stock-based compensation expense related to the CEO Performance Award and XSPP. An increase in litigation costs also contributed to the higher selling, general and administrative expense. For the six months ended June 30, 2020, we recorded a net loss of $26.7 million, which reflected income tax expense of $14.8 million, compared to net income of $7.2 million for the comparable period in the prior year.

COVID-19

In late 2019, COVID-19 was first detected in Wuhan, China. In March 2020 the World Health Organization declared COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread throughout the United States and world, has adversely affected workforces, economies, and financial markets globally, leading to an economic downturn. As an essential provider of products and services for law enforcement and other first responders, we remain focused on protecting the health and wellbeing of our employees while assuring the continuity of our business operations.

In response to the pandemic, Axon has taken a number of actions:

27

Customer support:

● Free access to Axon Citizen cloud software to all public law enforcement agencies for the remainder of 2020 to enable social distancing;

● A partnership with the National Police Foundation to provide personal protective equipment (“PPE”) for first responders;

● An online support center for our customers, www.axon.com/covid-19-support-center; and

● Our annual Axon Accelerate user conference will be held virtually in late August.

Employee safety and manufacturing:

● Curbed all non-essential travel at the beginning of March;

● We continue to allow for a remote work model for office staff, with medical screening for any employees who do work in our offices; and

● Mitigating contamination risk in our facilities through staggered shifts, the use of PPE, increased distancing, cleaning standards that exceed CDC guidance, access to an onsite registered nurse, and paying or subsidizing certain high-risk employees while they stay at home.

Supply chain:

● We previously took steps to diversify our supply chain and global manufacturing footprint, which have positioned us well to manage through the pandemic. Thus far, we have been able to produce and ship our critical core products with little to no interruption.

● We have proactively built up a safety stock of inventory to help meet strong product demand while also preparing us to stagger factory work schedules.

● We are continuously monitoring our supply chain to manage through potential impacts, finding alternate sources when available or working with foreign regulators to ensure that our suppliers can provide parts.

Shareholder engagement:

● We have pivoted our shareholder engagement to a virtual format.

o Our annual meeting was held virtually on May 29, 2020;

o We completed a follow-on equity offering in June 2020 for which all related marketing was conducted virtually; and

o We will continue to participate in several upcoming investor conferences utilizing video conferencing. All investor materials and events are available at investor.axon.com.

We are in a strong liquidity position, with substantial cash and investments on hand, which are discussed in more detail under Liquidity and Capital Resources. We believe that our existing liquidity and other sources of funding will be sufficient to satisfy our currently anticipated cash requirements including capital expenditures, working capital requirements, potential acquisitions and other liquidity requirements through at least the next 12 months. Our expenses for the three months and six months ended June 30, 2020 increased by approximately $2.5 million and $3.7 million, respectively, for costs related to the pandemic. We expect ongoing increased costs related to the mitigation of contamination risk at our facilities. We expect these incremental costs will continue to be partially offset by savings on travel and events and other cost-savings measures.  

We have elected to participate in the social security deferral program offered under the Coronavirus Aid, Relief, and Economic Security Act, whereby we can defer payment of the employer portion of all social security taxes that would otherwise be payable from March 27, 2020 through December 31, 2020. Payment of the deferred amount is due 50% on December 31, 2021 and 50% on December 31, 2022.

Net unit sales for TASER segment products and Software and Sensors segment products were as follows:

	Three Months Ended June 30,		Unit	Percent
	2020	2019	Change	Change
TASER 7	9,014	8,135	879	10.8
TASER X26P	7,658	9,493	(1,835)	(19.3)
TASER X2	13,100	9,759	3,341	34.2

Axon Dock	4,634	3,408	1,226	36.0
TASER Cam	794	1,716	(922)	(53.7)

Net sales for the TASER segment increased 16.4% primarily due to an increase of $4.5 million in cartridge revenue and a net increase of $7,320 million in TASER device sales. The increase in cartridge revenue was due to a combination of increased units and the higher average selling price for TASER 7 cartridges. Revenue for X2 devices increased on higher unit sales, partially offset by lower average selling prices. We continue to see a shift to purchases of our latest generation device, TASER 7, from legacy devices, especially X26P devices. Revenue was also impacted by higher average selling prices for TASER 7 and X26P. Revenue from consumer TASER devices increased due to both higher volume and a higher average selling price.

Net sales for the Software and Sensors segment increased 36.6% during the three months ended June 30, 2020 as we continued to add users and associated devices to our network. The increase in the aggregate number of users resulted in increased Axon Evidence revenue of $10.1 million. Sales of our newest generation body camera, Axon Body 3, which

30

began shipping in September 2019, drove the increase of $6.2 million in Axon Body revenue and the increase of $1.3 million in Axon Dock revenue.

We consider total company future contracted revenues a forward-looking performance indicator. As of June 30, 2020, we had approximately $1.34 billion of total company future contracted revenue, which included both recognized contract liabilities as well as amounts that will be invoiced and recognized in future periods. We expect to recognize between 20% - 25% of this balance over the next twelve months, and expect the remainder to be recognized over the following five to seven years, subject to risks related to delayed deployments, budget appropriation or other contract cancellation clauses.

Cost of Product and Service Sales

Within the TASER segment, cost of product sales increased to $27.2 million for the three months ended June 30, 2020 from $24.3 million for the same period in 2019. Cost as a percentage of sales decreased to 38.6% from 40.1%. During the prior year comparable period, cost of product sales included approximately $1.6 million in expense for TASER 7 ramp-up and optimization costs related to scrap, obsolete inventory, and higher labor costs. Partially offsetting the decrease was an increase in costs of approximately $0.8 million in response to COVID-19, primarily related to costs for employee quarantines and paying or subsidizing certain high-risk employees while they stay at home.

Within the Software and Sensors segment, cost of product and service sales increased to $25.8 million for the three months ended June 30, 2020 from $22.5 million for the same period in 2019. Cost as a percentage of sales decreased to 36.5% from 43.5%. Cost of product sales increased $2.6 million, but decreased as a percentage of sales as a result of the higher average selling prices during the quarter. Cost of service sales increased $0.7 million, and decreased as a percentage of sales, driven by the mix of higher-margin software revenues.

Gross Margin

As a percentage of net sales, gross margin for the TASER segment increased to 61.4% from 59.9% for the three months ended June 30, 2020 and 2019, respectively. The increase was primarily a result of the higher average selling prices in the current period for TASER 7 devices and cartridges, and non-recurring costs incurred in the prior year comparable period described above.

As a percentage of net sales, gross margin for the Software and Sensors segment increased to 63.5% from 56.5% for the three months ended June 30, 2020 and 2019, respectively. Within the Software and Sensors segment, hardware gross margin was 42.6% for the three months ended June 30, 2020 compared to 30.1% for the same period in 2019, while the service margins were 77.9% and 73.0% during those same periods, respectively. We expect hardware gross margin for the three months ending September 30, 2020 to be approximately 15% as we fulfill several large shipments of lower-margin body camera hardware to our largest customers.

Sales, General and Administrative Expenses

Sales, general and administrative ("SG&A") expenses were comprised as follows (dollars in thousands):

	Three Months Ended June 30,						Dollar		Percent
	2020			2019			Change		Change
Total sales, general and administrative expenses	$	72,293		$	43,362		$	28,931	66.7
Sales, general, and administrative as a percentage of net sales		51.2	%		38.6	%

Stock-based compensation expense increased $21.8 million in comparison to the prior year comparable period. During the three months ended June 30, 2020, attainment of the tenth and eleventh operational goals of the CEO Performance Award and XSPP became probable; during the prior year comparable period, only two operational goals were considered probable. Accordingly, we recorded additional expense of $14.8 million for the CEO Performance Award and $6.6 million for the XSPP, inclusive of cumulative expense for the tenth and eleventh tranches from the respective grant

31

dates through June 30, 2020. Stock-based compensation expense also increased over the prior year comparable period due to an increase in headcount.

Professional, consulting and lobbying expenses increased $3.9 million, driven by an increase of $3.8 million in expenses related to the FTC litigation. As discussed in Note 12 of the notes to our condensed consolidated financial statements within this Report on Form 10-Q, on January 3, 2020, we sued the FTC in the District of Arizona, and the FTC filed an enforcement action regarding our May 2018 acquisition of Vievu LLC. This litigation is expected to result in an increase in legal expenses during the year ending December 31, 2020. While the amount and timing of such expenses is unknown and will vary depending on the progression of litigation, we currently anticipate expenses in the range of $15.0 million to $22.0 million for the year.

Salaries, benefits and bonus expense increased $3.3 million, reflecting an increase of approximately $3.2 million in salaries, payroll taxes, and benefits, primarily due to an increase in headcount, and an increase in bonus expense of approximately $0.5 million, reflecting higher anticipated attainment as compared to the prior year.

Charitable contributions increased $1.7 million, reflecting our donations of PPE under the Got You Covered campaign.

Partially offsetting the noted increases were decreases resulting from actions taken in response to the COVID-19 pandemic. Travel expenses decreased $2.9 million following the suspension of all non-essential travel in mid-March 2020. Sales and marketing expenses decreased $1.3 million, driven by the cancellation of our in-person Axon Accelerate user conference; which will be held virtually in late August.

Research and Development Expenses

Research and development ("R&D") expenses were comprised as follows (dollars in thousands):

	Three Months Ended June 30,						Dollar		Percent
	2020			2019			Change		Change
Total research and development expenses	$	29,560		$	23,493		$	6,067	25.8
Research and development as a percentage of net sales		20.9	%		20.9	%

The increase in R&D expense was primarily attributable to our Software and Sensors segment. Within the TASER segment, R&D expense increased $0.7 million due to increased stock-based compensation and professional and consulting expense in the current quarter. R&D expense for the Software and Sensors segment increased $5.4 million, primarily due to an increase in salaries and benefits, inclusive of higher stock-based compensation, of $5.0 million. Contributing to the increase was an increase of approximately $2.3 million related to our XSPP, inclusive of cumulative expense for the tenth and eleventh operational goals from the respective grant dates through June 30, 2020. The remaining increase in salaries and benefits was primarily a result of increased headcount. Additionally, professional and consulting expenses increased $0.8 million for the three months ended June 30, 2020 related to development of next generation products, including the upcoming Fleet 3. The increases were partially offset by a decrease of $0.6 million in travel expense following the suspension of all non-essential travel in mid-March 2020 due to the COVID-19 pandemic.

We expect R&D expense to continue to increase in absolute dollars as we focus on growing the Software and Sensors segment as we add headcount and additional resources to develop new products and services to further advance our scalable cloud-connected device platform. We believe that these investments will result in an increase in our subscription revenue base, which over time will result in revenue increasing faster than the increase in SG&A expenses as we reach economies of scale.

Interest and Other Income (Expense), Net

Interest and other income (expense), net was $1.6 million for the three months ended June 30, 2020 compared to $1.8 million for the same period in 2019. The decrease was primarily attributable to a decrease of $0.5 million in interest

32

income as a result of decreased interest rates during the current period. The decrease was partially offset by a $0.4 million increase in investment gains related to assets held for our non-qualified deferred compensation plan.

Provision for Income Taxes

The provision for income taxes was an expense of $18.7 million for the three months ended June 30, 2020, which was an effective tax rate of (155.0%). Our estimated full year effective income tax rate for 2020, before discrete period adjustments, is (173.8%), which differs from the federal statutory rate primarily due to the impact of the executive compensation limitation under Internal Revenue Code ("IRC") Section 162(m) on a projected pre-tax loss for the year. The effective tax rate was favorably impacted by a $1.8 million discrete tax benefit primarily associated with windfalls related to stock-based compensation for RSUs that vested or stock options that were exercised during the three months ended June 30, 2020.

Net Income

Our net income decreased by $31.5 million to a loss of $30.8 million for the three months ended June 30, 2020 compared to net income of $0.7 million for the same period in 2019. Net loss per basic and diluted share was $0.51 for the three months ended June 30, 2020 compared to $0.01 net income per basic and diluted share for the same period in 2019.

Axon Dock	4,634	5,297	(663)	(12.5)	%
TASER Cam	794	1,514	(720)	(47.6)	%

Net sales within the TASER segment decreased by approximately $5.4 million or 7.1% as compared to the prior quarter. The largest driver of the decrease was lower cartridge revenue; the decrease in units was partially offset by a higher average sales price for TASER 7 cartridges. Additionally, sales of TASER devices decreased $1.5 million. Unit sales of TASER 7 and X26P devices declined from the prior quarter, while X2 and consumer TASER unit sales increased. The average selling prices increased for X26P and consumer TASER devices and declined slightly for TASER 7 and X2 devices.

Within the Software and Sensors segment, net sales decreased $0.5 million or 0.7% during the three months ended June 30, 2020 compared to the prior quarter. Revenue from Axon devices decreased a combined $3.5 million primarily due to lower unit sales. Lower average selling prices for Axon Flex and Axon Fleet also contributed to the decrease, while higher average selling prices for Axon Body cameras partially offset the decline. Axon Evidence revenues increased $2.7 million primarily based on an increase in the aggregate number of users on our Axon network.

Net sales for the TASER segment increased $20.4 million, or 16.2%, primarily due to an increase of $11.9 million in cartridge revenue, as well as a net increase of $7.3 million in TASER device sales. The increase in cartridge revenue was due to a combination of increased units and the higher average selling price for TASER 7 cartridges. As expected, we have continued to see a shift to purchases of our latest generation device, TASER 7, from legacy devices. Revenue from consumer TASER devices increased due to both higher volume and higher average selling prices. Revenue was also impacted by higher average selling prices for all TASER devices except X2 devices.  

Net sales for the Software and Sensors segment increased $39.8 million, or 39.0%, during the six months ended June 30, 2020 as we continued to add users and associated devices to our network. The increase in the aggregate number of users resulted in increased Axon Evidence revenue of $21.6 million. Sales of our newest generation body camera, Axon Body 3, which began shipping in September 2019, drove the increase of $12.6 million in Axon Body revenue and the increase of $3.0 million in Axon Dock revenue.

Cost of Product and Service Sales

Within the TASER segment, cost of product sales increased to $57.5 million for the six months ended June 30, 2020 from $47.5 million for the same period in 2019. Cost as a percentage of sales increased to 39.3% from 37.7%. The increase in cost of product sales was primarily attributable to the mix of products, with higher cost per unit for TASER 7 handles and cartridges as well as higher depreciation on new production equipment for the TASER 7. Additionally, we incurred expense of approximately $1.6 million in response to COVID-19, primarily related to a two week manufacturing shutdown where we continued to pay nonworking employees, as well as costs for employee quarantines and paying or subsidizing certain high-risk employees while they stay at home. The increases were partially offset by non-recurring costs incurred during the prior year comparable period of approximately $2.3 million for TASER 7 ramp-up and optimization costs related to scrap, obsolete inventory, and higher labor costs.

Within the Software and Sensors segment, cost of product and service sales increased to $54.1 million for the six months ended June 30, 2020 from $46.2 million for the same period in 2019. Cost as a percentage of sales decreased to 38.1% from 45.2%. Cost of product sales increased $4.9 million, but decreased as a percentage of sales as a result of the higher average selling prices during the quarter. Cost of service sales increased $3.1 million, and decreased as a percentage of sales, driven by the mix of higher-margin software revenues.

Gross Margin

As a percentage of net sales, gross margin for the TASER segment decreased to 60.7% from 62.3% for the six months ended June 30, 2020 and 2019, respectively. The decrease was primarily a result of the mix of higher cost TASER 7 devices and cartridges and expenses related to COVID-19.

As a percentage of net sales, gross margin for the Software and Sensors segment increased to 61.9% from 54.8% for the six months ended June 30, 2020 and 2019, respectively. Within the Software and Sensors segment, hardware gross margin was 42.3% for the six months ended June 30, 2020 compared to 29.2% for the same period in 2019, while the service margins were 76.6% and 73.3% during those same periods, respectively.

Sales, General and Administrative Expenses

Sales, general and administrative ("SG&A") expenses were comprised as follows (dollars in thousands):

	Six Months Ended June 30,						Dollar		Percent
	2020			2019			Change		Change
Total sales, general and administrative expenses	$	135,320		$	86,254		$	49,066	56.9	%
SG&A expenses as a percentage of net sales		46.9	%		37.8	%

36

Stock-based compensation expense increased $32.1 million in comparison to the prior year comparable period. During the six months ended June 30, 2020, attainment of the tenth and eleventh operational goals of the CEO Performance Award and XSPP became probable; during the prior year comparable period, only two operational goals were considered probable. Accordingly, we recorded additional expense of $20.3 million for the CEO Performance Award and $10.1 million for the XSPP, inclusive of cumulative expense for the tenth and eleventh operational goals from the respective grant dates through June 30, 2020. Stock-based compensation expense also increased over the prior year comparable period due to an increase in headcount.

Professional, consulting and lobbying expenses increased $10.2 million, driven by an increase of $10.0 million in expenses related to the FTC litigation. As discussed in Note 12 of the notes to our condensed consolidated financial statements within this Report on Form 10-Q, on January 3, 2020, we sued the FTC in the District of Arizona, and the FTC filed an enforcement action regarding our May 2018 acquisition of Vievu LLC. This litigation is expected to result in an increase in legal expenses during the year ending December 31, 2020. While the amount and timing of such expenses is unknown and will vary depending on the progression of litigation, we currently anticipate expenses in the range of $15.0 million to $22.0 million for the year.

Salaries, benefits and bonus expense increased $4.5 million, reflecting an increase of approximately $3.9 million in salaries, payroll taxes, and benefits, primarily due to an increase in headcount.

Charitable contributions increased $1.7 million, reflecting our donations of PPE under the Got You Covered campaign.

Partially offsetting the noted increases were decreases resulting from actions taken in response to the COVID-19 pandemic. Travel expenses decreased $2.5 million following the suspension of all non-essential travel in mid-March 2020. Sales and marketing expenses were relatively flat compared to the prior year period, reflecting savings driven by the cancellation of our in-person Axon Accelerate user conference, offset by increased commissions tied to higher revenues.

Research and Development Expenses

Research and development ("R&D") expenses were comprised as follows (dollars in thousands):

	Six Months Ended June 30,						Dollar		Percent
	2020			2019			Change		Change
Total research and development expenses	$	55,941		$	46,847		$	9,094	19.4	%
R&D expenses as a percentage of net sales		19.4	%		20.5	%

The increase in R&D expense was fully attributable to our Software and Sensors segment. R&D expense for the Software and Sensors segment increased $9.1 million, primarily due to a $7.9 million increase related to salaries and benefits from higher stock-based compensation and increased headcount. Additionally, professional and consulting expenses increased $1.3 million for the six months ended June 30, 2020 related to development of next generation products, including the upcoming Fleet 3. The increases were partially offset by a decrease of $0.7 million in travel expense following the suspension of all non-essential travel in mid-March 2020 due to the COVID-19 pandemic.

We expect R&D expense to continue to increase in absolute dollars as we focus on growing the Software and Sensors segment as we add headcount and additional resources to develop new products and services to further advance our scalable cloud-connected device platform. These investments include Axon Records and computer-aided dispatch software. We believe that these investments will result in an increase in our subscription revenue base, which over time will result in revenue increasing faster than the increase in SG&A expenses as we reach economies of scale.

Interest and Other Income (Expense), Net

Interest and other income, net was $2.6 million for the six months ended June 30, 2020 compared to $4.2 million for the same period in 2019. The decrease was primarily attributable to a decrease of $0.8 million in interest income

37

as a result of decreased interest rates during the current period, and a $0.6 million increase in investment losses related to assets held for our non-qualified deferred compensation plan.

Provision for Income Taxes

The provision for income taxes was an expense of $14.8 million for the six months ended June 30, 2020, which was an effective tax rate of (123.8%). Our estimated full year effective income tax rate for 2020, before discrete period adjustments, is (173.8%), which differs from the federal statutory rate primarily due to the impact of the executive compensation limitation under IRC Section 162(m) on a projected pre-tax loss for the year. The effective tax rate was favorably impacted by a $5.9 million discrete tax benefit primarily associated with windfalls related to stock-based compensation for RSUs that vested or stock options that were exercised during the six months ended June 30, 2020.

Net Income

Our net income decreased by $33.8 million to a net loss of $26.7 million for the six months ended June 30, 2020 compared to net income of $7.2 million for the same period in 2019. Net loss per basic and diluted share was $0.44 for the six months ended June 30, 2020 compared to $0.12 net income per basic and diluted share for the same period in 2019.

Non-GAAP Measures

To supplement our financial results presented in accordance with GAAP, we present the non-GAAP financial measures of EBITDA and Adjusted EBITDA (CEO Performance Award). Our management uses these non-GAAP financial measures in evaluating our performance in comparison to prior periods. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance, and when planning and forecasting our future periods. A reconciliation of GAAP to the non-GAAP financial measures is presented below.

● EBITDA (Most comparable GAAP Measure: Net income) - Earnings before interest expense, investment interest income, taxes, depreciation and amortization.

● Adjusted EBITDA (CEO Performance Award) (Most comparable GAAP Measure: Net income) - Earnings before interest expense, investment interest income, taxes, depreciation, amortization and non-cash stock-based compensation expense.

Although these non-GAAP financial measures are not consistent with GAAP, management believes investors will benefit by referring to these non-GAAP financial measures when assessing our operating results, as well as when forecasting and analyzing future periods. However, management recognizes that:

● these non-GAAP financial measures are limited in their usefulness and should be considered only as a supplement to our GAAP financial measures;

Liquidity and Capital Resources

Summary

As of June 30, 2020, we had $319.3 million of cash and cash equivalents, an increase of $147.0 million as compared to December 31, 2019. Cash and cash equivalents and investments totaled $686.8 million; including a net payable of $10.4 million related to unsettled investment purchases at June 30, 2020, this represented a net increase of $280.1 million from December 31, 2019.

Our ongoing sources of cash include cash on hand, investments, and cash flows from operations. In addition, our $50.0 million revolving credit facility is available for additional working capital needs or investment opportunities. Under the terms of the line of credit, available borrowings are reduced by outstanding letters of credit. Advances under the line of credit bear interest at LIBOR plus 1.0 to 1.5% per year determined in accordance with a pricing grid based on our funded debt to earnings before interest, taxes, depreciation and amortization ("EBITDA") ratio.

As of June 30, 2020, we had letters of credit outstanding of $6.1 million, leaving the net amount available for borrowing of $43.9 million. The facility matures on December 31, 2021, and has an accordion feature which allows for an increase in the total line of credit up to $100.0 million, subject to certain conditions, including the availability of additional bank commitments. There can be no assurance that we will continue to generate cash flows at or above current levels or that we will be able to maintain our ability to borrow under our revolving credit facility. At June 30, 2020 and December 31, 2019, there were no borrowings under the line other than the outstanding letters of credit.

Our agreement with the bank requires us to comply with a maximum funded debt to EBITDA ratio, as defined, of no greater than 2.50 to 1.00 based upon a trailing four fiscal quarter period. At June 30, 2020, our funded debt to EBITDA ratio was 0.0001 to 1.00.

TASER 60 installment purchase arrangements typically involve amounts invoiced in five equal installments at the beginning of each year of the five-year term. This is in contrast to a traditional CED sale in which the entire amount being charged for the hardware is invoiced upon shipment. This impacts liquidity in a commensurate fashion, with the cash for the TASER 60 arrangement received in five annual installments rather than up front. It is our strategic intent to shift an increasing amount of our business to a subscription model, to better match the municipal budgeting process of our customers as well as to allow for multiple product offerings to be bundled into existing subscriptions. We carefully considered the cash flow impacts of this strategic shift and regularly revisit our cash flow forecast with the goal of maintaining a comfortable level of liquidity as we introduce commercial offerings in which we incur upfront cash costs to produce and fulfill hardware sales ahead of the cash inflows from our customers. We anticipate, and have prepared for, the majority of our arrangements in both reportable segments to be offered in similar subscription-type offerings over the coming years. With the launch of the TASER 7, which is primarily being sold in subscription offerings, this strategic shift continues to accelerate.

39

Based on our strong balance sheet and the fact that we do not have long-term debt at June 30, 2020, we believe financing will be available, both through our existing credit line and possible additional financing. However, there is no assurance that such funding will be available on terms acceptable to us, or at all. We believe that our sources of funding will be sufficient to satisfy our currently anticipated cash requirements including capital expenditures, working capital requirements, potential acquisitions and other liquidity requirements through at least the next 12 months. We and our Board of Directors may consider repurchases of our common stock from time to time pursuant to our stock repurchase plan. Further repurchases of our common stock would take place on the open market, would be financed with available cash and are subject to market and business conditions.

Cash Flows

The following table summarizes our cash flows from operating, investing and financing activities (in thousands):

	Six Months Ended June 30,
	2020		2019
Operating activities	$	(6,977)	$	(2,576)
Investing activities		(146,211)		(124,878)
Financing activities		301,307		(2,028)
Effect of exchange rate changes on cash and cash equivalents		(1,115)		(252)
Net increase (decrease) in cash and cash equivalents and restricted cash	$	147,004	$	(129,734)

Operating activities

Net cash used in operating activities in the first six months of 2020 of $7.0 million reflects $26.7 million in net loss, non-cash income statement items totaling $59.0 million, and a use of cash of $39.3 million for the net change in operating assets and liabilities. Included in the non-cash items were $5.8 million in depreciation and amortization expense, $54.0 million in stock-based compensation expense, and a $6.1 million increase in deferred tax assets, net. Cash used in operations was primarily driven by increased inventory of $43.3 million, as we proactively built up a safety stock of inventory to help meet strong product demand while also preparing us to stagger factory work schedules. Also contributing to the use of cash were increased accounts and notes receivable and contract assets of $9.4 million, and increased prepaid and other assets of $8.6 million. The increase in accounts and notes receivable and contract assets was attributable to increased sales over the last several quarters, primarily sales made under subscription plans. The increase in prepaid expenses and other assets was primarily attributable to a $10.4 million receivable related to held-to-maturity securities sold at the end of the current quarter. Partially offsetting the uses of cash were increases in accounts payable, accrued liabilities and other liabilities of $16.7 million, and in deferred revenue of $5.2 million. The increase in accounts payable, accrued liabilities and other liabilities was primarily attributable to accruals for inventory in transit and taxes. The increase in deferred revenue was primarily attributable to increased hardware deferred revenue from TASER subscription sales, partially offset by a decrease in prepayments for Software and Sensors services.

Net cash used in operating activities in the first six months of 2019 of $2.6 million reflects $7.2 million in net income, non-cash income statement items totaling $24.7 million, and a negative impact on cash of $34.5 million for the net change in operating assets and liabilities. Included in the non-cash items were $5.5 million in depreciation and amortization expense and $16.5 million in stock-based compensation expense. Cash used in operations was impacted by increased accounts and notes receivable and contract assets of $11.0 million, decreased accounts payable, accrued liabilities and other liabilities of $16.8 million, increased inventory of $7.5 million, and increased prepaid expenses and other assets of $5.8 million. The increase in accounts and notes receivable and contract assets was attributable to increased sales over the last several quarters, primarily sales made under subscription plans. The decrease in accounts payable, accrued liabilities and other liabilities was primarily attributable to the timing of payments for our annual bonus plan. Cash used in operations was positively impacted by various other operating items, including increased deferred revenue of $6.6 million.

40

Investing activities

We used $146.2 million in investing activities during the first six months of 2020, which was comprised of $133.9 million for the purchase of investments, net of proceeds, $4.7 million for an equity investment in an unconsolidated affiliate, and $7.7 million for the purchase of property and equipment and intangible assets, which was partially offset by proceeds from the disposal of property and equipment of less than $0.1 million.

We used $124.9 million in investing activities during the first six months of 2019, which was comprised of $116.7 million for the purchase of investments, net of proceeds, and $8.2 million for the purchase of property and equipment and intangible assets.

Financing activities

Net cash provided by financing activities was $301.3 million during the first six months of 2020. During the first six months of 2020, we completed an equity offering that generated net proceeds of $306.8 million and received proceeds from options exercised of $0.3 million; the proceeds were partially offset by payments of income and payroll taxes of $5.8 million on behalf of employees who net-settled stock awards during the period.

Net cash used in financing activities was $2.0 million during the first six months of 2019.  During the first six months of 2019, we paid income and payroll taxes of $2.1 million on behalf of employees who net-settled stock awards during the period, which was partially offset by proceeds from options exercised of $0.1 million.

Off-Balance Sheet Arrangements

The discussion of off-balance sheet arrangements in Note 12 of the notes to our condensed consolidated financial statements within this Quarterly Report on Form 10-Q is incorporated by reference herein.

Critical Accounting Estimates

We have identified the following accounting estimates as critical to our business operations and the understanding of our results of operations. The preparation of financial statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. While we do not believe that a change in these estimates is reasonably likely, there can be no assurance that our actual results will not differ from these estimates. The effect of these estimates on our business operations are discussed below.

Stock-Based Compensation

We have historically granted stock-based compensation to key employees and non-employee directors as a means of attracting and retaining highly qualified personnel. Stock-based compensation awards primarily consist of service-based RSUs, performance-based RSUs, and performance-based options. Our stock-based compensation awards are classified as equity and measured at the fair market value of the underlying stock at the grant date. For service-based awards, we recognize RSU expense using the straight-line attribution method over the requisite service period. Vesting of performance-based RSUs and options is contingent upon the achievement of certain performance criteria related to our operating performance, as well as successful and timely development and market acceptance of future product introductions. For performance-based RSUs containing only performance conditions, compensation cost is recognized using the graded attribution model over the explicit or implicit service period. For awards containing multiple service, performance or market conditions, where all conditions must be satisfied prior to vesting, compensation expense is recognized over the requisite service period, which is defined as the longest explicit, implicit or derived service period, based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date. For both service-based and performance-based RSUs, we account for forfeitures as they occur as a reduction to stock-based compensation expense and additional paid-in-capital.

41

For performance-based awards, stock-based compensation expense is recognized over the expected performance achievement period of individual performance goals when the achievement of each individual performance goal becomes probable. For performance-based awards with a vesting schedule based entirely on the attainment of both performance and market conditions, stock-based compensation expense is recognized over the longer of the expected achievement period of the performance and market conditions, beginning at the point in time that the relevant performance condition is considered probable of achievement. The fair value of such awards is estimated on the grant date using Monte Carlo simulations. Refer to Note 10 of the notes to our condensed consolidated financial statements within this Report on Form 10-Q.

We have granted a total of 14.8 million performance-based awards (options and restricted stock units) of which 12.2 million are outstanding as of June 30, 2020, the vesting of which is contingent upon the achievement of certain performance criteria including the successful development and market acceptance of future product introductions, our future sales targets and operating performance and market capitalization. Compensation expense for performance awards will be recognized based on management’s best estimate of the probability of the performance criteria being satisfied using the most currently available projections of future product adoption and operating performance, adjusted at each balance sheet date. Changes in the subjective and probability-based assumptions can materially affect the estimate of the fair value of the awards and timing of recognition of stock-based compensation and consequently, the related amount recognized in our condensed consolidated statements of operations and comprehensive income (loss).

Allowance for Expected Credit Losses

We are exposed to the risk of credit losses primarily through sales of products and services. Our expected loss allowance for accounts receivable, notes receivable, and contract assets represents management’s best estimate and application of judgment considering a number of factors, including historical collection experience, published or estimated credit default rates for entities that represent our customer base, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. Our monitoring activities include account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible.

We review receivables for U.S. and international customers separately to better reflect different published credit default rates and economic and market conditions.

A majority of our customers are governmental agencies. Due to municipal government funding rules, certain of our contracts are subject to appropriation, termination for convenience, or similar cancellation clauses, which could allow our customers to cancel or not exercise options to renew contracts in the future. Economic slowdowns that negatively affect municipal tax collections and put pressure on law enforcement may increase this risk and negatively impact the realizability of our accounts and notes receivable and contract assets. We considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and recorded additional credit loss expense of approximately $0.8 million during the six months ended June 30, 2020.

Based on the balances of our financial instruments as of June 30, 2020, a hypothetical 25 percent increase in expected credit loss rates across all pools would result in a $0.7 million increase in the allowance for expected credit losses.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We typically invest in a limited number of financial instruments, consisting principally of investments in money market accounts, certificates of deposit, and corporate and municipal bonds with a typical long-term debt rating of “A” or better by any nationally recognized statistical rating organization, denominated in U.S. dollars. All of our cash equivalents and investments are treated as “held-to-maturity.” Investments in fixed-rate interest-earning instruments carry a degree of interest rate risk as their market value may be adversely impacted due to a rise in interest rates. As a result, we may suffer losses in principal if we sell securities that have declined in market value due to changes in interest rates. However, because

42

we classify our debt securities as “held-to-maturity” based on our intent and ability to hold these instruments to maturity, no gains or losses are recognized due to changes in interest rates. These securities are reported at amortized cost. Based on investment positions as of June 30, 2020, a hypothetical 100 basis point increase in interest rates across all maturities would result in a $0.7 million decline in the fair market value of the portfolio. Such losses would only be realized if we sold the investments prior to maturity.

Additionally, we have access to a $50.0 million line of credit borrowing facility which bears interest at LIBOR plus 1.0 to 1.5% per year determined in accordance with a pricing grid based on our funded debt to EBITDA ratio. Under the terms of the line of credit, available borrowings are reduced by outstanding letters of credit, which totaled $6.1 million at June 30, 2020. At June 30, 2020, there was no amount outstanding under the line of credit and the available borrowing under the line of credit was $43.9 million. We have not borrowed any funds under the line of credit since its inception; however; should we need to do so in the future, such borrowings could be subject to adverse or favorable changes in the underlying interest rate.

Exchange Rate Risk

Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates, in each case compared to the U.S. dollar, related to transactions by our foreign subsidiaries. The majority of our sales to international customers are transacted in U.S. dollars and therefore, are not subject to exchange rate fluctuations on these transactions. However, the cost of our products to our customers increases when the U.S. dollar strengthens against their local currency, and we may have more sales and expenses denominated in foreign currencies in future years which could increase our foreign exchange rate risk. Additionally, intercompany sales to our non-U.S. dollar functional currency international subsidiaries are transacted in U.S. dollars which could increase our foreign exchange rate risk caused by foreign currency transaction gains and losses.

To date, we have not engaged in any currency hedging activities. However, we may enter into foreign currency forward and option contracts with financial institutions to protect against foreign exchange risks associated with certain existing assets and liabilities, certain firmly committed transactions, forecasted future cash flows and net investments in foreign subsidiaries. However, we may choose not to hedge certain foreign exchange exposures for a variety of reasons, including but not limited to the prohibitive economic cost of hedging particular exposures. As such, fluctuations in currency exchange rates could harm our business in the future.

Item 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer are responsible for the evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2020.

Change in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the fiscal quarter ended June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the potential impact of COVID-19 on our internal controls to minimize the impact on their design and operating effectiveness.

PART II - OTHER INFORMATION

Item 1.    Legal Proceedings

The discussion under the headings Product Litigation, Other Litigation, and U.S. Federal Trade Commission Investigation in Note 12 of the notes to our condensed consolidated financial statements included within this Quarterly Report on Form 10-Q is incorporated by reference herein.

Item 1A.    Risk Factors

Except as noted below, there are no material changes from the risk factors previously disclosed in Part I, Item 1A, "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2019, which could adversely affect our business, financial condition, results of operations, cash flows, and the trading price of our common stock.

The COVID-19 pandemic has significantly impacted worldwide economic conditions and could have a material adverse effect on our operations and business.

In March 2020 the World Health Organization declared coronavirus (or “COVID-19”) a global pandemic. This contagious disease outbreak, which has continued to spread throughout the United States and world, has adversely affected workforces, economies, and financial markets globally, leading to an economic downturn. As an essential provider of products and services for law enforcement and other first responders, we remain focused on protecting the health and well-being of our employees while assuring the continuity of our business operations.

​
COVID-19-related risks that may affect our operations and financial results include, but are not limited to:

● Manufacturing disruptions at our Scottsdale headquarters or at our suppliers;

● A change in our classification as an essential business that impairs our ability to continue operating;

● Economic slowdowns that negatively affect municipal tax collections and put pressure on law enforcement budgets that in turn increases the risk that our customers will be unable to appropriate funds for existing or future contracts with us; this could also affect customer demand and ability to pay, cause decreases in sales, and negatively impact the realizability of our accounts and notes receivable and contract assets;

● Existing and potential increased costs relating to personal protective equipment, which we are sourcing for our employees and customers;

● Costs incurred to shut down and decontaminate our facilities if the virus is detected;

● Extended illness, incapacitation or death of key personnel or executives;

● Ongoing governmental mandates to shutdown factories or limit travel and the movement of people;

● Compounding risk from the potential for second and third wave infections around the world, including in the U.S.; and

● Additional airline bankruptcies or further reduction in very limited global freight capacity that causes interruptions to our supply chain or extended supply chain.

These events have had and could continue to have an impact on our operations. If our backup and mitigation plans are not sufficient to minimize business disruption, our financial results could be adversely affected. The ultimate extent of the effects of the COVID-19 pandemic on the Company is highly uncertain and will depend on future developments that cannot be predicted. We are continuously monitoring our operations and intend to take appropriate actions to mitigate the risks arising from the COVID-19 pandemic, but there can be no assurances that we will be successful in doing so.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Summary of Significant Accounting Policies

1. Organization and Summary of Significant Accounting Policies

Axon Enterprise, Inc. (“Axon,” the “Company,” "we," or "us") is a market-leading provider of law enforcement technology solutions. Our core mission is to protect life. We fulfill that mission through developing hardware and software products that advance the long term objectives of a) obsoleting the bullet, b) reducing social conflict, and c) enabling a fair and effective justice system.

Our headquarters in Scottsdale, Arizona houses our executive management, sales, marketing, certain engineering, manufacturing, and other administrative support functions. We also have a software engineering development center located in Seattle, Washington, and subsidiaries located in Australia, Canada, Finland, Hong Kong, Germany, India, Italy, the Netherlands, the United Kingdom, and Vietnam.

The accompanying unaudited condensed consolidated financial statements include the accounts of Axon Enterprise, Inc. and our wholly owned subsidiaries. All material intercompany accounts, transactions, and profits have been eliminated.

Basis of Presentation and Use of Estimates

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information related to our organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) has been condensed or omitted. The accounting policies followed in the preparation of these unaudited condensed consolidated financial statements are consistent with those followed in our annual consolidated financial statements for the year ended December 31, 2019, as filed on Form 10-K, with the exception of our adoption of certain accounting pronouncements which we describe below. In the opinion of management, these unaudited condensed consolidated financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary to fairly state our financial position, results of operations and cash flows for the periods presented and the presentations and disclosures herein are adequate when read in conjunction with our Form 10-K for the year ended December 31, 2019. The results of operations for the three months and six months ended June 30, 2020 and 2019 are not necessarily indicative of the results to be expected for the full year (or any other period). Significant estimates and assumptions in these unaudited condensed consolidated financial statements include:

● product warranty reserves,

● inventory valuation,

● revenue recognition,

● expected credit loss reserves,

● valuation of goodwill, intangible and long-lived assets,

● recognition, measurement and valuation of current and deferred income taxes,

● stock-based compensation,

● recognition and measurement of lease liabilities,

● recognition and measurement of contingencies and accrued litigation expense, and

● fair values of identified tangible and intangible assets acquired and liabilities assumed in business combinations.

Actual results could differ materially from those estimates.

Segment Information

Our operations are comprised of two reportable segments: the manufacture and sale of conducted electrical devices ("CEDs"), batteries, accessories, extended warranties and other products and services (the “TASER” segment);

and the development, manufacture, and sale of software and sensors, which includes the sale of devices, wearables, applications, cloud and mobile products, and services (collectively, the “Software and Sensors” segment). In both segments, we report sales of products and services. Service revenue in both segments includes sales related to Axon Evidence. In the Software and Sensors segment, service revenue also includes other recurring cloud-hosted software revenue and related professional services. Collectively, this revenue is sometimes referred to as "Axon Cloud revenue."  

Reportable segments are determined based on discrete financial information reviewed by our Chief Executive Officer who is our chief operating decision maker ("CODM"). We organize and review operations based on products and services, and currently there are no operating segments that are aggregated. We perform an analysis of our reportable segments at least annually. Additional information related to our business segments is summarized in Note 14.

Geographic Information and Major Customers / Suppliers

For the three and six months ended June 30, 2020 and 2019, no individual country outside the U.S. represented more than 10% of total net sales. Individual sales transactions in the international market are generally larger and occur more intermittently than in the domestic market due to the profile of our customers. For the three and six months ended June 30, 2020 and 2019, no customer represented more than 10% of total net sales. At June 30, 2020 and December 31, 2019, no customer represented more than 10% of the aggregate balance of accounts and notes receivable and contract assets.

We currently purchase both off the shelf and custom components, including, but not limited to, finished circuit boards, injection-molded plastic components, small machined parts, custom cartridge components, electronic components, and off the shelf sub-assemblies from suppliers located in the U.S., Canada, China, Israel, Mexico, Republic of Korea, Sri Lanka, and Taiwan. Although we currently obtain many of these components from single source suppliers, we own the injection molded component tooling, most of the designs, and the test fixtures used in their production for all custom components. As a result, we believe we could obtain alternative suppliers in most cases without incurring significant production delays. We also strategically hold safety stock levels on custom components to further reduce this risk. For off the shelf components, we believe that in most cases there are readily available alternative suppliers who can consistently meet our needs for these components. We acquire most of our components on a purchase order basis and do not have any significant long-term contracts with component suppliers.

Income per Common Share

Basic income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the periods presented. Diluted income per share reflects the potential dilution from outstanding stock options and unvested restricted stock units. The calculation of the weighted average number of shares outstanding and earnings per share are as follows (in thousands except per share data):

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019

Diluted	$	(0.51)	$	0.01	$	(0.44)	$	0.12

Standard Warranties

We warranty our CEDs, Axon cameras and certain related accessories from manufacturing defects on a limited basis for a period of one year after purchase and, thereafter, will repair or replace any defective unit for a fee. Estimated costs for the standard warranty are charged to cost of products sold when revenue is recorded for the related product. Future warranty costs are estimated based on historical data related to warranty claims and this rate is applied to current product sales. Historically, reserve amounts have been increased if management becomes aware of a component failure or other issue that could result in larger than anticipated warranty claims from customers. The warranty reserve is reviewed quarterly to verify that it sufficiently reflects the remaining warranty obligations based on the anticipated expenditures over the balance of the warranty obligation period, and adjustments are made when actual warranty claim experience differs from estimates. The warranty reserve is included in accrued liabilities on the accompanying condensed consolidated balance sheets.

Changes in our estimated product warranty liabilities were as follows (in thousands):

	Six Months Ended June 30,
	2020		2019
Balance, beginning of period	$	1,476	$	898
Utilization of reserve		(350)		(250)
Warranty expense (benefit)		(114)		634
Balance, end of period	$	1,012	$	1,282

Fair Value Measurements and Financial Instruments

We use the fair value framework that prioritizes the inputs to valuation techniques for measuring financial assets and liabilities measured on a recurring basis and for non-financial assets and liabilities when these items are re-measured. Fair value is considered to be the exchange price in an orderly transaction between market participants, to sell an asset or transfer a liability at the measurement date. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

● Level 1 – Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

● Level 2 – Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets

or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.

● Level 3 – Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect our own assumptions about inputs that market participants would use in pricing an asset or liability.

We have cash equivalents and investments, which at June 30, 2020 and December 31, 2019 were comprised of money market funds, certificates of deposit, commercial paper, corporate bonds, corporate notes, municipal bonds, U.S. Government agency bonds, U.S. Treasury bills, U.S. Treasury inflation-protected securities, and U.S. Treasury repurchase agreements. See additional disclosure regarding the fair value of our cash equivalents and investments in Note 3. Included in the balance of other assets as of June 30, 2020 and December 31, 2019 was $4.0 million and $4.2 million, respectively, related to corporate-owned life insurance policies which are used to fund our deferred compensation plan. We determine the fair value of insurance contracts by obtaining the cash surrender value of the contracts from the issuer, a Level 2 valuation technique. In March 2020, we made an investment of $4.7 million in preferred stock and recorded preferred stock warrants at a fair value of $2.6 million, which is also included in the balance of other assets as of June 30, 2020. The estimated fair value of the investments was determined based on Level 3 inputs. As of June 30, 2020, management estimated that the fair value of the investment equaled its carrying value.

Our financial instruments also include accounts and notes receivable, accounts payable and accrued liabilities. Due to the short-term nature of these instruments, their fair values approximate their carrying values on the balance sheet.

Restricted Cash

Restricted cash balances as of June 30, 2020 and December 31, 2019 included $0.1 million primarily related to funds held in an international bank account for a country in which we are required to maintain a minimum balance to operate. Approximately half of the balance was included in prepaid expenses and other current assets on our condensed consolidated balance sheets, with the remainder included in other assets.

Valuation of Goodwill, Intangibles and Long-lived Assets

We evaluate whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets and identifiable intangible assets, excluding goodwill and intangible assets with indefinite useful lives, may warrant revision or that the remaining balance of these assets may not be recoverable. Such circumstances could include, but are not limited to, a change in the product mix, a change in the way products are created, produced or delivered, or a significant change in the way products are branded and marketed. In performing the review for recoverability, we estimate the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. The amount of the impairment loss, if impairment exists, is calculated based on the excess of the carrying amounts of the assets over their estimated fair value computed using discounted cash flows.

We do not amortize goodwill and intangible assets with indefinite useful lives; rather such assets are required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired. We perform our annual goodwill and intangible asset impairment tests in the fourth quarter of each year.

Recently Issued Accounting Guidance

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial

Instruments. ASU 2016-13 includes an impairment model (known as the current expected credit loss model) on financial instruments and other commitments that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The use of forecasted information is intended to incorporate more timely information in the estimate of expected credit loss. This ASU also requires enhanced disclosures relating to significant estimates and judgments used in estimating credit losses, as well as credit quality. Upon adoption, we recorded a noncash cumulative effect adjustment to retained earnings of $0.6 million, net of $0.2 million of income taxes, on the opening consolidated balance sheet as of January 1, 2020,  reflecting an overall increase to the allowance for expected credit losses. See Notes 3 and 4 for further disclosures related to Topic 326.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 eliminates, adds and modifies certain disclosure requirements for fair value measurements. The amendments apply to the disclosures of changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Adoption of this ASU on January 1, 2020 did not have a material impact on our consolidated financial statements.

Effective the first quarter of 2021:

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in the ASU are effective for fiscal years beginning after December 15, 2020, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. Adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

In January 2020, the FASB issued ASU No. 2020-01, Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (a Consensus of the Emerging Issues Task Force). The guidance clarifies the interaction between ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities and the ASU on equity method investments. ASU 2016-01 provides companies with an alternative to measure certain equity securities without a readily determinable fair value at cost, minus impairment, if any, unless an observable transaction for an identical or similar security occurs. ASU 2020-01 clarifies that for purposes of applying the Topic 321 measurement alternative, an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting under Topic 323, immediately before applying or upon discontinuing the equity method. In addition, the new ASU provides direction that a company should not consider whether the underlying securities would be accounted for under the equity method or the fair value option when it is determining the accounting for certain forward contracts and purchased options, upon either settlement or exercise. The amendments in this update become effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, and the amendments are to be applied prospectively. Adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

Reclassification of Prior Year Presentation

Certain prior year amounts, including the long-term portion of contract assets, have been reclassified for consistency with the current year presentation. These reclassifications are not material and had no effect on the reported results of operations.

Remaining Performance Obligations

As of June 30, 2020, we had approximately $1.34 billion of remaining performance obligations, which included both recognized contract liabilities as well as amounts that will be invoiced and recognized in future periods. The remaining performance obligations are limited only to arrangements that meet the definition of a contract under Topic 606 as of June 30, 2020. We expect to recognize between 20% - 25% of this balance over the next twelve months, and generally expect the remainder to be recognized over the following five to seven years, subject to risks related to delayed deployments, budget appropriation or other contract cancellation clauses.

As of June 30, 2020, the balances reflected above were offset by a net payable of $10.4 million related to unsettled investment purchases, which was settled in early July. We believe unrealized losses on our investments are due to interest rate fluctuations.

We adopted Topic 326 on January 1, 2020, and applied the credit loss guidance related to held-to-maturity securities prospectively. Because we do not have any history of losses for our held-to-maturity investments, our expected loss allowance methodology for held-to-maturity investments is developed using published or estimated credit default rates for similar investments and current and future economic and market conditions. At both January 1 and June 30, 2020, our credit loss reserve for held-to-maturity investments was approximately $0.1 million. During the three and six months ended June 30, 2020, we increased the frequency of review for our investment portfolio in order to more closely monitor potential impacts of the novel coronavirus ("COVID-19”) pandemic.

Expected Credit Losses

4. Expected Credit Losses

We are exposed to credit losses primarily through sales of products and services. Our expected loss allowance methodology for accounts receivable, notes receivable, and contract assets is developed using historical collection experience, published or estimated credit default rates for entities that represent our customer base, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. Our monitoring activities include account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible.

We considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and recorded additional credit loss expense of approximately $0.8 million during the six months ended June 30, 2020.

We review receivables for U.S. and international customers separately to better reflect different published credit default rates and economic and market conditions.

The following table provides a roll-forward of the allowance for expected credit losses that is deducted from the amortized cost basis of accounts receivable, notes receivable, and contract assets to present the net amount expected to be collected (in thousands):

(1) Represents the incremental costs of obtaining contracts with customers, which consist primarily of sales commissions. These costs are ascribed to or allocated to the underlying performance obligations in the contracts and amortized consistent with the recognition timing of the revenue for the underlying performance obligations.

(2) In March 2020, we made an investment in and entered into a commercial partnership agreement with Flock Group Inc., a provider of advanced security for neighborhoods and law enforcement. Our $4.7 million investment resulted in our ownership of approximately 5% of the outstanding equity interests of this company. We account for this investment under the ASC 321 measurement alternative for equity securities without readily determinable fair values, as there are no quoted market prices for the investment. The investment is measured at cost less impairment, adjusted for observable price changes and is assessed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. As of June 30, 2020, no impairment was recorded for the investment.

(3) In conjunction with the equity investment in and commercial partnership with Flock Group, Inc., we have the ability to commit additional capital over time through warrants where the exercisability and exercise prices are conditional on the achievement of certain partnership performance metrics. The fair value of the preferred stock warrants was estimated at $2.6 million using Monte Carlo simulation.

Income Tax Disclosure [Abstract]

Income Taxes

9. Income Taxes

We file income tax returns for federal purposes and in many states, as well as in multiple foreign jurisdictions. Our tax filings remain subject to examination by applicable tax authorities for a certain length of time, generally three to four years, following the tax year to which these filings relate. In July 2020, we received notification from the Internal Revenue Service that the audit of  our U.S. federal income tax return for fiscal year 2016 was completed. During the second quarter we began an audit with the State of California for our fiscal year 2016 and 2017 state tax returns, which is currently ongoing. Additionally, we have been notified that an audit will commence for Axon Public Safety Southeast Asia LLC, our entity in Vietnam. The tax period has not yet been defined.

On March 27, 2020, the U.S. federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The CARES Act is an emergency economic stimulus package in response to the coronavirus outbreak which, among other things, contains numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for years ending before the date of enactment. We are continuing to evaluate the implications of the CARES Act, but its impact on our financial statements and related disclosures is not expected to be material.

In April 2020, recent interpretations of a German law relating to withholding taxes on intellectual property rights emerged.  We have evaluated this law and do not expect a material impact to our financial position or results of operations.

Deferred Tax Assets

Net deferred income tax assets at June 30, 2020, primarily include R&D tax credits, stock-based compensation expense, deferred revenue, accruals and reserves, and net operating losses, partially offset by accelerated depreciation expense and valuation allowance reserve. Our total net deferred tax assets at June 30, 2020 were $33.7 million.

In preparing our condensed consolidated financial statements, management assesses the likelihood that its deferred tax assets will be realized from future taxable income. In evaluating our ability to recover our deferred income tax assets, management considers all available positive and negative evidence, including our operating results, ongoing tax planning and forecasts of future taxable income on a jurisdiction by jurisdiction basis. A valuation allowance is established if it is determined that it is more likely than not that some portion or all of the net deferred tax assets will not be realized. Management exercises significant judgment in determining our provisions for income taxes, our deferred tax assets and liabilities, and our future taxable income for purposes of assessing our ability to utilize any future tax benefit from our deferred tax assets.

As of June 30, 2020, we continue to demonstrate three-year cumulative pre-tax income in the U.S. federal and state tax jurisdictions; however, we have Arizona R&D Tax Credits expiring unutilized each year. Therefore, management has concluded that it is more likely than not that our Arizona R&D deferred tax asset will not be realized.

As of June 30, 2020, we have cumulative pre-tax losses in the U.K. and Canada, which limits the ability to consider other subjective evidence, such as projections for future growth. On the basis of this evaluation, a full valuation allowance has been recorded for these jurisdictions. The amount of the deferred tax asset considered realizable, however, could be adjusted in future periods if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as projections for growth.

In Australia, we have determined that sufficient deferred tax liabilities will reverse in order to realize all assets except one long-lived intangible where there is not an expectation that the asset may be realized. Therefore, we have recorded a partial valuation allowance for Australia.

We complete R&D tax credit studies for each year that an R&D tax credit is claimed for federal, Arizona, and California income tax purposes. Management has made the determination that it is more likely than not that the full benefit of the R&D tax credit will not be sustained on examination and recorded a liability for unrecognized tax benefits of $6.9 million as of June 30, 2020. Should the unrecognized benefit of $6.9 million be recognized, our effective tax rate would be favorably impacted. Approximately $2.7 million of the unrecognized tax benefit associated with R&D credits has been netted against the R&D deferred tax asset.

Effective Tax Rate

Our overall effective tax rate for the six months ended June 30, 2020, after discrete period adjustments, was  (123.8%). Before discrete adjustments, the tax rate was (173.8%), which differs from the federal statutory rate, primarily due to the impact of the executive compensation limitation under Internal Revenue Code ("IRC") Section 162(m) on a projected pre-tax loss for the year. The effective tax rate was favorably impacted by a $5.9 million discrete tax benefit primarily associated with windfalls related to stock-based compensation for restricted stock units (“RSUs”) that vested or stock options that were exercised during the six months ended June 30, 2020.

Equity [Abstract]

Stockholders' Equity

10. Stockholders’ Equity

Follow-on offering

In June 2020, we sold 3,450,000 shares of our common stock, which included 450,000 shares pursuant to the full exercise of the underwriters' option to purchase additional shares, in an underwritten public offering at a price of $92.00 per

share, which resulted in gross proceeds of $317.4 million. Net proceeds to us after deducting fees, commissions, and other expenses related to the offering were $306.8 million.

Performance-based stock awards

We have issued performance-based stock options and performance-based RSUs, the vesting of which is generally contingent upon the achievement of certain performance criteria related to our operating performance, as well as successful and timely development and market acceptance of future product introductions. In addition, certain of the performance RSUs have additional service requirements subsequent to the achievement of the performance criteria. Compensation expense is recognized over the requisite service period, which is defined as the longest explicit, implicit or derived service period based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date. For both service-based and performance-based RSUs, we account for forfeitures as they occur as a reduction to stock-based compensation expense and additional paid-in-capital.

For performance-based options with a vesting schedule based entirely on the attainment of both performance and market conditions, stock-based compensation expense is recognized for each pair of performance and market conditions over the longer of the expected achievement period of the performance and market conditions, beginning at the point in time that the relevant performance condition is considered probable of achievement. The fair value of such awards is estimated on the grant date using Monte Carlo simulations.

CEO Performance Award

On May 24, 2018, our stockholders approved the Board of Directors’ grant of 6,365,856 stock option awards to Patrick W. Smith, our CEO (the “CEO Performance Award”). The CEO Performance Award consists of 12 vesting tranches with a vesting schedule based entirely on the attainment of both operational goals (performance conditions) and market capitalization goals (market conditions), assuming continued employment either as the CEO or as both Executive Chairman and Chief Product Officer and service through each vesting date. Each of the 12 vesting tranches of the CEO Performance Award have a 10-year contractual term and will vest upon certification by the Board of Directors that both (i) the market capitalization goal for such tranche, which begins at $2.5 billion for the first tranche and increases by increments of $1.0 billion thereafter, and (ii) any one of the following eight operational goals focused on revenue or eight operational goals focused on Adjusted EBITDA have been met for the previous four consecutive fiscal quarters. Adjusted EBITDA for purposes of the CEO Performance Award ("Adjusted EBITDA (CEO Performance Award)") is defined as net income (loss) attributable to common stockholders before interest expense,  investment interest income, provision (benefit) for income taxes, depreciation and amortization, and stock-based compensation expense.

	Eight Separate Adjusted EBITDA (CEO
Eight Separate Revenue Goals (1)	Performance Award) Goals

Goal #1, $710,058	Goal #9, $125,000

Goal #7, $1,810,058	Goal #15, $220,000
Goal #8, $2,010,058	Goal #16, $230,000

(1) In connection with the business acquisition that was completed during the three months ended June 30, 2018, the revenue goals were adjusted for the acquiree’s Target Revenue, as defined in the CEO Performance Award agreement.

As of June 30, 2020, the following operational goals were considered probable of achievement:

● Total revenue of $710.1 million, $860.1 million, and $1,010.1 million; and

● Adjusted EBITDA (CEO Performance Award) of $125.0 million, $155.0 million, $175.0 million, $190.0 million, $200.0 million, $210.0 million, $220.0 million, and $230.0 million.

The first three market capitalization goals have been achieved as of June 30, 2020. However, none of the stock options granted under the CEO Performance Award have vested thus far as the operational goals have not yet been achieved as of June 30, 2020. As there are eleven operational goals considered probable of achievement, we recorded stock-based compensation expense of $60.5 million related to the CEO Performance Award from the Grant Date through June 30, 2020. The number of stock options that would vest related to the eleven tranches is approximately 5.8 million shares.

As of June 30, 2020, we had $167.9 million of total unrecognized stock-based compensation expense for the performance goals that were considered probable of achievement, which will be recognized over a weighted-average period of 5.31 years. As of June 30, 2020, we had unrecognized stock-based compensation expense of $17.6 million for the performance goals that were considered not probable of achievement.

eXponential Stock Performance Plan

On February 12, 2019, our shareholders approved the 2019 Stock Incentive Plan (the “2019 Plan”), which was adopted by the Board of Directors to reserve a sufficient number of shares to facilitate our eXponential Stock Performance Plan (“XSPP”) and grants of eXponential Stock Units (“XSUs”) under the plan. Initial awards under the plan were granted in January 2019, with additional employee awards granted since that date. During the three and six months ended June 30, 2020, we granted an additional 0.1 million and 0.2 million XSUs, respectively.

The XSUs are grants of RSUs, each with a term of approximately nine years, that vest in 12 equal tranches. Each of the 12 tranches will vest upon certification by the Compensation Committee of the Board of Directors that both (i) the market capitalization goal for such tranche, which begins at $2.5 billion for the first tranche and increases by increments of $1.0 billion thereafter, and (ii) any one of eight operational goals focused on revenue or eight operational goals focused on Adjusted EBITDA (CEO Performance Award) have been met for the previous four consecutive fiscal quarters.

The XSPP contains an anti-dilution provision incorporated into the plan based on shareholder feedback, which affects the calculation of the market capitalization goals in the plan. The plan defines a maximum number of shares outstanding that may be used in the calculation of the market capitalization goals (the “XSU Maximum”). If the actual number of shares outstanding exceeds the XSU Maximum guardrail, then the lower pre-defined number of shares in the XSU Maximum, rather than the higher actual number of shares outstanding, is used to calculate market capitalization for the determination of the market capitalization goals in the XSPP, which, together with the operational goals, determines whether XSUs vest for participating employees.

The XSU Maximum is defined as the actual number of shares outstanding on the original XSU grant date of January 2, 2019, increased by a 3% annual rate over the term of the XSPP and by shares issued upon the exercise of CEO Performance Award options. The XSU Maximum is also adjusted for acquisitions, spin-offs or other changes in the number of outstanding shares of common stock, if such changes have a corresponding adjustment on the market capitalization goals.

New shares issued for any other reasons, including shares issued upon vesting of XSUs, RSUs, and PSUs as well as shares issued to raise capital through equity issuances or in other transactions, do not increase the XSU Maximum.

The market capitalization and operational goals are identical to the CEO Performance Award, but a different number of shares is used to calculate the market capitalization goals if shares outstanding exceed the XSU Maximum. Additionally, because the grant date is different than that of the CEO Performance Award, the measurement period for market capitalization is not identical.

As of June 30, 2020, actual shares outstanding exceeded the XSU Maximum as a result of the common stock offering completed in June 2020. Accordingly, market capitalization as calculated for the purposes of achieving additional goals uses the lower XSU Maximum share amount rather than actual shares outstanding. The first three market capitalization goals have been achieved as of June 30, 2020. However, none of the XSU tranches have vested thus far as the operational goals have not yet been achieved as of June 30, 2020. As there are eleven operational goals considered probable of achievement, we recorded stock-based compensation expense of $33.8 million related to the XSU awards from their respective grant dates through June 30, 2020. The number of XSU awards that would vest related to the eleven tranches is approximately 5.0 million shares.

As of June 30, 2020, we had $148.1 million of total unrecognized stock-based compensation expense for the performance goals that were considered probable of achievement, which will be recognized over a weighted-average period of 5.12 years. As of June 30, 2020, we had unrecognized stock-based compensation expense of $11.4 million for the performance goals that were considered not probable of achievement.

Restricted Stock Units

The following table summarizes RSU activity for the six months ended June 30, 2020 (number of units and aggregate intrinsic value in thousands):

	Number of	Weighted Average		Aggregate

Released	(303)		36.90
Forfeited	(68)		46.85
Units outstanding, end of period	1,067		52.93	$	104,743

Aggregate intrinsic value represents our closing stock price on the last trading day of the period, which was $98.13 per share, multiplied by the number of RSUs outstanding. As of June 30, 2020, there was $42.4 million in unrecognized compensation costs related to RSUs under our stock plans for shares that are expected to vest. We expect to recognize the cost related to the RSUs over a weighted average period of 2.04 years. RSUs are released when vesting requirements are met.

Certain RSUs that vested in the six months ended June 30, 2020 were net-share settled such that we withheld shares to cover the employees’ tax obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. Total shares withheld related to RSUs were approximately 0.1 million and had a value of $4.6 million on their respective vesting dates as determined by the closing stock price on such dates. Payments for the employees’ tax obligations are reflected as a financing activity within the condensed consolidated statements of cash flows. We record a liability for the tax withholding to be paid by us as a reduction to additional paid-in capital.

Performance Stock Units

The following table summarizes Performance Stock Units (“PSUs”) activity, inclusive of XSUs, for the six months ended June 30, 2020 (number of units and aggregate intrinsic value in thousands):

Units outstanding, beginning of year	6,033	$	34.47
Granted	229		49.90
Released	(158)		24.88
Forfeited	(303)		36.10
Units outstanding, end of period	5,801		35.26	$	569,207

Aggregate intrinsic value represents our closing stock price on the last trading day of the period, which was $98.13 per share, multiplied by the number of PSUs outstanding. As of June 30, 2020, there was $152.6 million in unrecognized compensation costs related to PSUs under our stock plans for shares that are expected to vest. We expect to recognize the cost related to the PSUs over a weighted average period of 5.03 years. PSUs are released when vesting requirements are met.

As of June 30, 2020, the performance criteria had been met for approximately 0.1 million of the 5.8 million PSUs outstanding. Certain of the PSUs outstanding as of June 30, 2020 can vest with a range of shares earned being between 0% and 200% of the targeted shares granted, depending on the final achievement of pre-determined performance criteria as of the vesting date. The amount of PSUs included in the table above related to such grants is the target level. The maximum additional number of PSUs that could be earned is 0.2 million, which are not included in the table above.

Certain PSUs that vested in the six months ended June 30, 2020 were net-share settled such that we withheld shares to cover the employees’ tax obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. Total shares withheld related to PSUs were approximately 16 thousand and had a value of $1.2 million on their respective vesting dates as determined by the closing stock price on such dates. Payments for the employees’ tax obligations are reflected as a financing activity within the condensed consolidated statements of cash flows. We record a liability for the tax withholding to be paid by us as a reduction to additional paid-in capital.

Stock Option Activity

Total stock-based compensation expense	$	33,835	$	8,627	$	54,030	$	16,532

Stock Incentive Plan

In February 2019, our shareholders approved the 2019 Plan authorizing an additional 6.0 million shares, plus remaining available shares under prior plans, for issuance under the new plan. Combined with the legacy stock incentive plans, there are 2.0 million shares available for grant as of June 30, 2020.

Stock Repurchase Plan

In February 2016, our Board of Directors authorized a stock repurchase program to acquire up to $50.0 million of our outstanding common stock subject to stock market conditions and corporate considerations. During the six months ended June 30, 2020 and 2019, no common shares were purchased under the program. As of June 30, 2020, $16.3 million remains available under the plan for future purchases. Any future purchases will be discretionary.

Line of Credit

11. Line of Credit

We have a $50.0 million unsecured revolving line of credit with a domestic bank, of which $10.0 million is available for letters of credit. The credit agreement matures on December 31, 2021 and has an accordion feature which allows for an increase in the total line of credit up to $100.0 million, subject to certain conditions, including the availability of additional bank commitments.

At June 30, 2020 and December 31, 2019, there were no borrowings under the line. Under the terms of the line of credit, available borrowings are reduced by outstanding letters of credit. As of June 30, 2020, we had letters of credit outstanding of approximately $6.1 million under the facility and available borrowing of $43.9 million, excluding amounts available under the accordion feature. Advances under the line of credit bear interest at LIBOR plus 1.0 to 1.5% per year determined in accordance with a pricing grid based on our funded debt to earnings before interest, taxes, depreciation and amortization ("EBITDA") ratio.

We are required to comply with a maximum funded debt to EBITDA ratio of no greater than 2.50 to 1.00 based upon a trailing four fiscal quarter period. At June 30, 2020, our funded debt to EBITDA ratio was 0.0001 to 1.00.

Product Litigation

As a manufacturer of weapons and other law enforcement tools used in high-risk field environments, we are often the subject of products liability litigation concerning the use of our products.  We are currently named as a defendant in eight lawsuits in which the plaintiffs allege either wrongful death or personal injury in situations in which a TASER CED was used by law enforcement officers in connection with arrests or training. While the facts vary from case to case, these product liability claims typically allege defective product design, manufacturing, and/or failure to warn. They seek compensatory and sometimes punitive damages, often in unspecified amounts.

We continue to aggressively defend all product litigation. As a general rule, it is our policy not to settle suspect injury or death cases. Exceptions are sometimes made where the settlement is strategically beneficial to us. Due to the confidential nature of our litigation strategy and the confidentiality agreements that are executed in the event of a settlement, we do not identify or comment on specific settlements by case or amount. Based on current information, we do not believe that the outcome of any such legal proceeding will have a material effect on our financial position, results of operations, or cash flows. We are self-insured for the first $5.0 million of any product claim made after 2014. No judgment or settlement has ever exceeded this amount in any products case. We continue to maintain product liability insurance coverage, including an insurance policy fronting arrangement, above our self-insured retention with various limits depending on the policy period.

Other Litigation

We are a defendant in a consumer class action lawsuit filed in the District of Nevada on April 9, 2019 by Douglas Richey (“Richey”). The case alleges the TASER Pulse, X2 and X26P CEDs have a faulty safety switch based on Richey’s Pulse allegedly discharging inside its neoprene case in a jacket pocket without injury. Any such discharge was likely due to static electricity, as disclosed in our consumer warnings. The nationwide class allegations have been withdrawn and any applicable class is limited to California purchasers. We are vigorously defending this suit and the propriety of any class certification.

The litigation information in this note is current through the date of these financial statements.

U.S. Federal Trade Commission Litigation

The U.S. Federal Trade Commission (“FTC”) filed an enforcement action on January 3, 2020 regarding Axon’s May 2018 acquisition of Vievu LLC from Safariland LLC. The FTC alleges the merger was anticompetitive and adversely affected the body worn camera (“BWC”) and digital evidence management systems (“DEMS”) market for “large metropolitan police departments.” The stay of the administrative proceedings due to the COVID-19 pandemic lifted July 7 and discovery is underway.  The hearing has been reset for October 13, 2020. If successful, the FTC may require us to divest Vievu and other assets or take other remedial measures, any of which could be material to Axon. We are vigorously defending the matter. At this time, we cannot predict the eventual scope, duration, or outcome of this request and accordingly we have not recorded any liability in the accompanying condensed consolidated financial statements.

Also, on January 3, 2020, we sued the FTC in the U.S. District of Arizona for declaratory and injunctive relief alleging the FTC’s structure and administrative processes violate Article II of the U.S. Constitution and our Fifth Amendment rights to due process and equal protection. On April 8, 2020, the district court dismissed the action, without prejudice, for lack of jurisdiction, requiring Axon to first bring its constitutional claims in the administrative case. Axon has appealed that ruling to the Ninth Circuit (No. 20-15662), which granted expedited consideration and heard oral argument on July 17.  The matter is now under advisement.

In parallel to these matters, we are evaluating strategic alternatives to litigation, which we might pursue if determined to be in the best interests of shareholders and customers. This could include a divestiture of the Vievu entity and/or related assets and the licensure of certain intellectual and other intangible property. While we continue to believe the acquisition of Vievu in 2018 was lawful and a benefit to Vievu's customers, the cost, risk and distraction of protracted litigation merit consideration of settlement if achievable on terms agreeable to the FTC and us.

General

From time to time, we are notified that we may be a party to a lawsuit or that a claim is being made against us. It is our policy to not disclose the specifics of any claim or threatened lawsuit until the summons and complaint are actually served on us. After carefully assessing the claim, and assuming we determine that we are not at fault or we disagree with the damages or relief demanded, we vigorously defend any lawsuit filed against us. We record a liability when losses are deemed probable and reasonably estimable. When losses are deemed reasonably possible but not probable, we determine whether it is possible to provide an estimate of the amount of the loss or range of possible losses for the claim, if material for disclosure. In evaluating matters for accrual and disclosure purposes, we take into consideration factors such as our historical experience with matters of a similar nature, the specific facts and circumstances asserted, the likelihood of our prevailing, the availability of insurance, and the severity of any potential loss. We reevaluate and update accruals as matters progress over time.

Based on our assessment of outstanding litigation and claims as of June 30, 2020, we have determined that it is not reasonably possible that these lawsuits will individually, or in the aggregate, materially affect our results of operations, financial condition or cash flows. However, the outcome of any litigation is inherently uncertain and there can be no assurance that any expense, liability or damages that may ultimately result from the resolution of these matters will be covered by our insurance or will not be in excess of amounts recognized or provided by insurance coverage and will not have a material adverse effect on our operating results, financial condition or cash flows.

Off-Balance Sheet Arrangements

Under certain circumstances, we use letters of credit and surety bonds to guarantee our performance under various contracts, principally in connection with the installation and integration of Axon cameras and related technologies. Certain of our letters of credit and surety bonds have stated expiration dates with others being released as the contractual performance terms are completed. At June 30, 2020, we had outstanding letters of credit of $6.1 million that are expected to expire in June 2021 and September 2021. We also had outstanding letters of credit and bank guarantees of $1.9 million that do not draw against our credit facility. The outstanding letters of credit are expected to expire in June 2021. Additionally, we had $24.0 million of outstanding surety bonds at June 30, 2020, with $0.5 million expiring in 2020, $2.3 million expiring in 2021, $3.2 million expiring in 2022, $7.5 million expiring in 2023 and the remaining $10.5 million expiring in 2024.

Employee Benefit Plans

13. Employee Benefit Plans

We have a defined contribution 401(k) plan for eligible employees, which is qualified under Sections 401(a) and 401(k) of the Internal Revenue Code of 1986, as amended. Employees are entitled to make tax-deferred contributions of up to the maximum amount allowed by law of their eligible compensation.

We also have a non-qualified deferred compensation plan for certain executives, employees and non-employee directors through which participants may elect to postpone the receipt and taxation of a portion of their compensation, including stock-based compensation, received from us. The non-qualified deferred compensation plan allows eligible participants to defer up to 80% of their base salary and up to 100% of other types of compensation. The plan also allows for matching and discretionary employer contributions. Employee deferrals are deemed 100% vested upon contribution. Distributions from the plan are made upon retirement, death, separation of service, specified date or upon the occurrence of an unforeseeable emergency. Distributions can be paid in a variety of forms from lump sum to installments over a period

of years. Participants in the plan are entitled to select from a wide variety of investments available under the plan and are allocated gains or losses based upon the performance of the investments selected by the participant. All gains or losses are allocated fully to plan participants and we do not guarantee a rate of return on deferred balances. Assets related to this plan consist of corporate-owned life insurance contracts and are included in other assets in the condensed consolidated balance sheets; see Note 7 for balances. Participants have no rights or claims with respect to any plan assets and any such assets are subject to the claims of our general creditors.

Contributions to the plans are made by both the employee and us. Our contributions to the 401(k) plan are based on the level of employee contributions and are immediately vested. Future matching contributions to the plans are at our sole discretion.

We also sponsor defined contribution plans in Australia, Finland, and the United Kingdom.

Our matching contributions for all defined contribution plans were $1.3 million and $1.1 million for the three months ended June 30, 2020 and 2019, respectively and $2.8 million and $2.5 million for the six months ended June 30, 2020 and 2019, respectively.

Segment Data

14. Segment Data

Our operations are comprised of two reportable segments: the manufacture and sale of CEDs, batteries, accessories, extended warranties and other products and services (the “TASER” segment); and the software and sensors business, which includes the sale of devices, wearables, applications, cloud and mobile products, and services (collectively, the “Software and Sensors” segment). In both segments, we report sales of products and services. Service revenue in both segments includes sales related to Axon Evidence. In the Software and Sensors segment, service revenue also includes other recurring cloud-hosted software revenue and related professional services. Collectively, this revenue is sometimes referred to as "Axon Cloud revenue." Our Chief Executive Officer, who is the CODM, is not provided asset information or sales, general, and administrative expense by segment.

Basis of Presentation and Use of Estimates

Basis of Presentation and Use of Estimates

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information related to our organization, significant accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) has been condensed or omitted. The accounting policies followed in the preparation of these unaudited condensed consolidated financial statements are consistent with those followed in our annual consolidated financial statements for the year ended December 31, 2019, as filed on Form 10-K, with the exception of our adoption of certain accounting pronouncements which we describe below. In the opinion of management, these unaudited condensed consolidated financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary to fairly state our financial position, results of operations and cash flows for the periods presented and the presentations and disclosures herein are adequate when read in conjunction with our Form 10-K for the year ended December 31, 2019. The results of operations for the three months and six months ended June 30, 2020 and 2019 are not necessarily indicative of the results to be expected for the full year (or any other period). Significant estimates and assumptions in these unaudited condensed consolidated financial statements include:

● product warranty reserves,

● inventory valuation,

● revenue recognition,

● expected credit loss reserves,

● valuation of goodwill, intangible and long-lived assets,

● recognition, measurement and valuation of current and deferred income taxes,

● stock-based compensation,

● recognition and measurement of lease liabilities,

● recognition and measurement of contingencies and accrued litigation expense, and

● fair values of identified tangible and intangible assets acquired and liabilities assumed in business combinations.

Actual results could differ materially from those estimates.

Segment Information

Segment Information

Our operations are comprised of two reportable segments: the manufacture and sale of conducted electrical devices ("CEDs"), batteries, accessories, extended warranties and other products and services (the “TASER” segment);

and the development, manufacture, and sale of software and sensors, which includes the sale of devices, wearables, applications, cloud and mobile products, and services (collectively, the “Software and Sensors” segment). In both segments, we report sales of products and services. Service revenue in both segments includes sales related to Axon Evidence. In the Software and Sensors segment, service revenue also includes other recurring cloud-hosted software revenue and related professional services. Collectively, this revenue is sometimes referred to as "Axon Cloud revenue."  

Reportable segments are determined based on discrete financial information reviewed by our Chief Executive Officer who is our chief operating decision maker ("CODM"). We organize and review operations based on products and services, and currently there are no operating segments that are aggregated. We perform an analysis of our reportable segments at least annually. Additional information related to our business segments is summarized in Note 14.

Geographic Information and Major Customers / Suppliers

Geographic Information and Major Customers / Suppliers

For the three and six months ended June 30, 2020 and 2019, no individual country outside the U.S. represented more than 10% of total net sales. Individual sales transactions in the international market are generally larger and occur more intermittently than in the domestic market due to the profile of our customers. For the three and six months ended June 30, 2020 and 2019, no customer represented more than 10% of total net sales. At June 30, 2020 and December 31, 2019, no customer represented more than 10% of the aggregate balance of accounts and notes receivable and contract assets.

We currently purchase both off the shelf and custom components, including, but not limited to, finished circuit boards, injection-molded plastic components, small machined parts, custom cartridge components, electronic components, and off the shelf sub-assemblies from suppliers located in the U.S., Canada, China, Israel, Mexico, Republic of Korea, Sri Lanka, and Taiwan. Although we currently obtain many of these components from single source suppliers, we own the injection molded component tooling, most of the designs, and the test fixtures used in their production for all custom components. As a result, we believe we could obtain alternative suppliers in most cases without incurring significant production delays. We also strategically hold safety stock levels on custom components to further reduce this risk. For off the shelf components, we believe that in most cases there are readily available alternative suppliers who can consistently meet our needs for these components. We acquire most of our components on a purchase order basis and do not have any significant long-term contracts with component suppliers.

Income per Common Share

Income per Common Share

Basic income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the periods presented. Diluted income per share reflects the potential dilution from outstanding stock options and unvested restricted stock units. The calculation of the weighted average number of shares outstanding and earnings per share are as follows (in thousands except per share data):

Standard Warranties

Standard Warranties

We warranty our CEDs, Axon cameras and certain related accessories from manufacturing defects on a limited basis for a period of one year after purchase and, thereafter, will repair or replace any defective unit for a fee. Estimated costs for the standard warranty are charged to cost of products sold when revenue is recorded for the related product. Future warranty costs are estimated based on historical data related to warranty claims and this rate is applied to current product sales. Historically, reserve amounts have been increased if management becomes aware of a component failure or other issue that could result in larger than anticipated warranty claims from customers. The warranty reserve is reviewed quarterly to verify that it sufficiently reflects the remaining warranty obligations based on the anticipated expenditures over the balance of the warranty obligation period, and adjustments are made when actual warranty claim experience differs from estimates. The warranty reserve is included in accrued liabilities on the accompanying condensed consolidated balance sheets.

Changes in our estimated product warranty liabilities were as follows (in thousands):

	Six Months Ended June 30,
	2020		2019
Balance, beginning of period	$	1,476	$	898

Balance, end of period	$	1,012	$	1,282

Fair Value Measurements and Financial Instruments

Fair Value Measurements and Financial Instruments

We use the fair value framework that prioritizes the inputs to valuation techniques for measuring financial assets and liabilities measured on a recurring basis and for non-financial assets and liabilities when these items are re-measured. Fair value is considered to be the exchange price in an orderly transaction between market participants, to sell an asset or transfer a liability at the measurement date. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

● Level 1 – Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

● Level 2 – Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets

or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.

● Level 3 – Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect our own assumptions about inputs that market participants would use in pricing an asset or liability.

We have cash equivalents and investments, which at June 30, 2020 and December 31, 2019 were comprised of money market funds, certificates of deposit, commercial paper, corporate bonds, corporate notes, municipal bonds, U.S. Government agency bonds, U.S. Treasury bills, U.S. Treasury inflation-protected securities, and U.S. Treasury repurchase agreements. See additional disclosure regarding the fair value of our cash equivalents and investments in Note 3. Included in the balance of other assets as of June 30, 2020 and December 31, 2019 was $4.0 million and $4.2 million, respectively, related to corporate-owned life insurance policies which are used to fund our deferred compensation plan. We determine the fair value of insurance contracts by obtaining the cash surrender value of the contracts from the issuer, a Level 2 valuation technique. In March 2020, we made an investment of $4.7 million in preferred stock and recorded preferred stock warrants at a fair value of $2.6 million, which is also included in the balance of other assets as of June 30, 2020. The estimated fair value of the investments was determined based on Level 3 inputs. As of June 30, 2020, management estimated that the fair value of the investment equaled its carrying value.

Our financial instruments also include accounts and notes receivable, accounts payable and accrued liabilities. Due to the short-term nature of these instruments, their fair values approximate their carrying values on the balance sheet.

Restricted cash

Restricted Cash

Restricted cash balances as of June 30, 2020 and December 31, 2019 included $0.1 million primarily related to funds held in an international bank account for a country in which we are required to maintain a minimum balance to operate. Approximately half of the balance was included in prepaid expenses and other current assets on our condensed consolidated balance sheets, with the remainder included in other assets.

Valuation of Goodwill, Intangibles and Long-lived Assets

Valuation of Goodwill, Intangibles and Long-lived Assets

We evaluate whether events and circumstances have occurred that indicate the remaining estimated useful life of long-lived assets and identifiable intangible assets, excluding goodwill and intangible assets with indefinite useful lives, may warrant revision or that the remaining balance of these assets may not be recoverable. Such circumstances could include, but are not limited to, a change in the product mix, a change in the way products are created, produced or delivered, or a significant change in the way products are branded and marketed. In performing the review for recoverability, we estimate the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. The amount of the impairment loss, if impairment exists, is calculated based on the excess of the carrying amounts of the assets over their estimated fair value computed using discounted cash flows.

We do not amortize goodwill and intangible assets with indefinite useful lives; rather such assets are required to be tested for impairment at least annually or sooner whenever events or changes in circumstances indicate that the assets may be impaired. We perform our annual goodwill and intangible asset impairment tests in the fourth quarter of each year.

Recently Issued Accounting Guidance

Recently Issued Accounting Guidance

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial

Instruments. ASU 2016-13 includes an impairment model (known as the current expected credit loss model) on financial instruments and other commitments that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. The use of forecasted information is intended to incorporate more timely information in the estimate of expected credit loss. This ASU also requires enhanced disclosures relating to significant estimates and judgments used in estimating credit losses, as well as credit quality. Upon adoption, we recorded a noncash cumulative effect adjustment to retained earnings of $0.6 million, net of $0.2 million of income taxes, on the opening consolidated balance sheet as of January 1, 2020,  reflecting an overall increase to the allowance for expected credit losses. See Notes 3 and 4 for further disclosures related to Topic 326.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 eliminates, adds and modifies certain disclosure requirements for fair value measurements. The amendments apply to the disclosures of changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Adoption of this ASU on January 1, 2020 did not have a material impact on our consolidated financial statements.

Effective the first quarter of 2021:

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in the ASU are effective for fiscal years beginning after December 15, 2020, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. Adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

In January 2020, the FASB issued ASU No. 2020-01, Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (a Consensus of the Emerging Issues Task Force). The guidance clarifies the interaction between ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities and the ASU on equity method investments. ASU 2016-01 provides companies with an alternative to measure certain equity securities without a readily determinable fair value at cost, minus impairment, if any, unless an observable transaction for an identical or similar security occurs. ASU 2020-01 clarifies that for purposes of applying the Topic 321 measurement alternative, an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting under Topic 323, immediately before applying or upon discontinuing the equity method. In addition, the new ASU provides direction that a company should not consider whether the underlying securities would be accounted for under the equity method or the fair value option when it is determining the accounting for certain forward contracts and purchased options, upon either settlement or exercise. The amendments in this update become effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, and the amendments are to be applied prospectively. Adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

Reclassification of Prior Year Presentation

(1) Represents the incremental costs of obtaining contracts with customers, which consist primarily of sales commissions. These costs are ascribed to or allocated to the underlying performance obligations in the contracts and amortized consistent with the recognition timing of the revenue for the underlying performance obligations.

(2) In March 2020, we made an investment in and entered into a commercial partnership agreement with Flock Group Inc., a provider of advanced security for neighborhoods and law enforcement. Our $4.7 million investment resulted in our ownership of approximately 5% of the outstanding equity interests of this company. We account for this investment under the ASC 321 measurement alternative for equity securities without readily determinable fair values, as there are no quoted market prices for the investment. The investment is measured at cost less impairment, adjusted for observable price changes and is assessed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. As of June 30, 2020, no impairment was recorded for the investment.

(3) In conjunction with the equity investment in and commercial partnership with Flock Group, Inc., we have the ability to commit additional capital over time through warrants where the exercisability and exercise prices are conditional on the achievement of certain partnership performance metrics. The fair value of the preferred stock warrants was estimated at $2.6 million using Monte Carlo simulation.
