ALARM.COM HOLDINGS, INC.

Notes to the Condensed Consolidated Financial Statements (Unaudited)

Note 1. Organization

Alarm.com Holdings, Inc. (referred to herein as Alarm.com, the Company, or we) is the leading platform for the intelligently connected property. We offer a comprehensive suite of cloud-based solutions for the smart residential and commercial property, including interactive security, video monitoring, intelligent automation and energy management. Millions of property owners depend on our technology to intelligently secure, automate and manage their residential and commercial properties. Our solutions are delivered through an established network of over 10,000 trusted service provider partners, who are experts at selling, installing and supporting our solutions. We derive revenue from the sale of our cloud-based Software-as-a-Service, or SaaS, services, license fees, software, hardware, activation fees and other revenue. Our fiscal year ends on December 31.

Note 2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include our accounts and those of our majority-owned and controlled subsidiaries after elimination of intercompany accounts and transactions.

These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual financial statements. They should be read together with our audited consolidated financial statements and related notes thereto for the year ended December 31, 2020 included in our Annual Report on Form 10-K filed with the SEC on February 25, 2021, or the Annual Report. The condensed consolidated balance sheet as of December 31, 2020 was derived from our audited financial statements, but does not include all disclosures required by GAAP for annual financial statements.

In the opinion of management, these condensed consolidated financial statements include all normal recurring adjustments necessary for a fair statement of the results of operations, financial position and cash flows for the periods presented. However, the COVID-19 pandemic disrupted and may continue to disrupt our supply chain for an unknown period of time due to its impact on manufacturing, production and global transportation. The COVID-19 pandemic also disrupted and may intermittently continue to disrupt our sales channels due to restrictions imposed from time to time on our service providers’ ability to meet with residential and commercial property owners who use our solutions. In addition, the COVID-19 pandemic resulted in a global slowdown of economic activity and a recession in the United States and the economic situation remains fluid as parts of the economy appear to be recovering while others continue to struggle. While vaccines have been approved for use in the United States and in many other countries, and vaccination efforts are underway, it remains difficult to assess or predict the ultimate duration and economic impact of the COVID-19 pandemic. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results that can be expected for our entire fiscal year ending December 31, 2021, which is increasingly true in periods of extreme uncertainty, such as the uncertainty caused by the COVID-19 pandemic. Prolonged uncertainty with respect to COVID-19 could cause further economic slowdown or cause other unpredictable events, each of which could adversely affect our business, results of operations or financial condition.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. As of the date of issuance of these financial statements, we are not aware of any specific event or circumstance that would require us to update our estimates, assumptions and judgments or revise the carrying value of our assets or liabilities. However, our estimates, judgments and assumptions are continually evaluated based on available information and experience and may change as new events occur and additional information is obtained. Because of the use of estimates inherent in the financial reporting process and in light of the continuing uncertainty arising from the COVID-19 pandemic, actual results could differ from those estimates and any such differences may be material. Estimates are used when accounting for revenue recognition, allowances for credit losses, allowance for hardware returns, estimates of obsolete inventory, long-term incentive compensation, the lease term and incremental borrowing rates for leases, stock-based compensation, income taxes, legal reserves, fair value of the debt component of convertible notes, contingent consideration and goodwill and intangible assets.

Comprehensive Income

Our comprehensive income for the three and six months ended June 30, 2021 and 2020 was equal to our net income disclosed in the condensed consolidated statements of operations.

Notes to the Condensed Consolidated Financial Statements (Unaudited) — (Continued)

Significant Accounting Policies

Other than those disclosed herein, there have been no other material changes to our significant accounting policies during the three and six months ended June 30, 2021 from those disclosed in our Annual Report.

Convertible Senior Notes

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes in a private placement to qualified institutional buyers due January 15, 2026. In accounting for the issuance of our convertible senior notes, we separate the notes into liability and equity components. The carrying amount of the liability component is calculated by measuring the fair value of a similar liability that does not have an associated convertible feature, using a discounted cash flow model with a risk adjusted yield. The carrying amount of the equity component representing the conversion option is determined by deducting the fair value of the liability component from the par value of the notes as a whole. This difference represents a debt discount that is amortized to interest expense using the effective interest method over the term of the notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the transaction costs related to the issuance of the notes, we allocate the total amount incurred to the liability and equity components using the same proportions as the proceeds from the notes. Transaction costs attributable to the liability component are netted with the liability component and amortized to interest expense using the effective interest method over the term of the notes. Transaction costs attributable to the equity component are netted with the equity component of the notes in additional paid-in capital in the condensed consolidated balance sheets. See Note 12 for the carrying amount and estimated fair value of our convertible senior notes as of June 30, 2021.

Recent Accounting Pronouncements

Adopted

On December 18, 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes," which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The update also simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance to improve consistent application. The amendment in this update was effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. On January 1, 2021, we adopted Topic 740. This pronouncement did not have a material impact on our condensed consolidated financial statements or disclosures.

Not Yet Adopted

On March 12, 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued such as the Eurodollar Base Rate, or LIBOR. The update allows entities to elect not to apply certain modification accounting requirements to contracts affected by the discontinuation of a reference rate if certain criteria are met. The amendment was effective beginning March 12, 2020 and will continue to be effective through December 31, 2022. Due to the termination of our credit facility on January 20, 2021 (see Note 12), this pronouncement is not expected to have an impact on our condensed consolidated financial statements or disclosures.

On August 5, 2020, the FASB issued ASU 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity," which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The new guidance eliminates two of the three models in Subtopic 470-20 that require separating embedded conversion features from convertible instruments. The guidance also addresses how convertible instruments are accounted for in the diluted earnings per share calculation. The amendment in this update is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The guidance allows for either full retrospective adoption or modified retrospective adoption. We are currently assessing the impact this pronouncement may have on our consolidated financial statements when we adopt the pronouncement on January 1, 2022.

Note 3. Revenue from Contracts with Customers

Revenue Recognition

We derive our revenue from three primary sources: the sale of cloud-based SaaS services on our integrated Alarm.com platform, the sale of licenses and services on our non-hosted software platform, or Software platform, and the sale of hardware products. We sell our platform and hardware solutions to service provider partners that resell our solutions and hardware to residential and commercial property owners, who are the service provider partners’ customers. Our subscribers consist of all of the properties maintained by those residential and commercial property owners to which we are delivering at least one of our solutions. We also sell our hardware to distributors who resell the hardware to service provider partners. We enter into contracts with our service provider partners that establish pricing for access to our platform solutions and for the sale of hardware. These service provider contracts typically have an initial term of one year, with subsequent renewal terms of one year. Our service provider partners typically enter into contracts with our subscribers, which our service provider partners have indicated range from three to five years in length.

When determining the amount of consideration we expect to be entitled to for the sale of our hardware, we estimate the variable consideration associated with customer returns. We record a reserve against revenue for hardware returns based on historical returns. For the twelve months ended June 30, 2021 and 2020, our reserve against revenue for hardware returns was 1%. We evaluate our hardware reserve on a quarterly basis or if there is an indication of significant changes in return experience. Historically, our returns of hardware have not significantly differed from our estimated reserve. Additionally, we provide warranties related to the intended functionality of the products and services provided and those warranties typically allow for the return of hardware up to one year past the date of sale. We determined that these warranties are not separate performance obligations as they cannot be purchased separately and do not provide a service in addition to an assurance the hardware will function as expected.

Our hardware and other revenue also includes our revenue from the sale of perpetual licenses that provide our customers in the commercial market the right to use our OpenEye video surveillance software for an indefinite period of time in exchange for a one-time license fee, which is generally paid at contract inception. Our hardware and other revenue also includes our revenue from Shooter Detection Systems related to the sale of licenses that provide our customers the right to use our indoor gunshot detection solution in exchange for license fees, which are generally paid at contract inception. Our perpetual licenses and licenses to our indoor gunshot detection solution provide a right to use intellectual property that is functional in nature and has significant stand-alone functionality. Accordingly, for licenses of functional intellectual property, revenue is recognized at the point-in-time when control has been transferred to the customer, which occurs once the software has been made available to the customer.

Hardware and other revenue may also include activation fees charged to some of our service provider partners for activation of a new subscriber account on our platforms, as well as fees paid by service provider partners for our marketing services. Our service provider partners use services on our platforms, such as support tools and applications, to assist in the installation of our solutions in subscriber properties. This installation marks the beginning of the service period on our platforms and, on occasion, we earn activation revenue for fees charged for this service. The activation fee is non-refundable, separately negotiated and specified in our contractual arrangements with our service provider partners and is charged to the service provider partner for each subscriber activated on our platforms. The decision whether to charge an activation fee is based in part on the expected number of subscribers to be added by our service provider partners and as a result, many of our largest service provider partners do not pay an activation fee. Activation fees are not offered on a stand-alone basis separate from our SaaS offering and are billed and received at the beginning of the arrangement. We record activation fees initially as deferred revenue and we recognize these fees ratably over the expected term of the subscribers’ account which we estimate is ten years based on our annual attrition rate. The portion of these activation fees included in current and long-term deferred revenue as of our balance sheet date represents the amounts that will be recognized ratably as revenue over the following twelve months, or longer as appropriate, until the ten-year expected term is complete. The balance of deferred revenue for activation fees was $6.5 million and $7.0 million as of June 30, 2021 and December 31, 2020, respectively, which combines current and long-term balances.

SaaS and license revenue associated with our contracts is invoiced and revenue is recognized at an amount that corresponds directly with the value of the performance completed to date. Additionally, the consideration received from hardware sales corresponds directly with the stand-alone selling price of the hardware. As a result, we have elected to use the practical expedient related to the amount of transaction price allocated to the unsatisfied performance obligations and therefore, we have not disclosed the total remaining revenue expected to be recognized on all contracts or the expected period over which the remaining revenue would be recognized. 

Contract Assets

At contract inception, we assess the goods and services promised in our contracts with customers and identify a performance obligation for each distinct promise to transfer a good or service, or bundle of goods or services. To identify the performance obligations, we consider all of the goods or services promised in the contract, whether explicitly stated or implied

based on customary business practices. We record a contract asset when we satisfy a performance obligation by transferring a promised good or service. Contract assets can be conditional or unconditional depending on whether another performance obligation must be satisfied before payment can be received. We receive payments from our service provider partners based on the billing schedule established in our contracts. All of the accounts receivable presented in the condensed consolidated balance sheets represent unconditional rights to consideration. We do not have any assets from contracts containing conditional rights and we do not have any assets from satisfied performance obligations that have not been invoiced.

We recognize an asset related to the costs incurred to obtain a contract only if we expect to recover those costs and we would not have incurred those costs if the contract had not been obtained. We recognize an asset from the costs incurred to fulfill a contract if the costs (i) are specifically identifiable to a contract, (ii) enhance resources that will be used in satisfying performance obligations in future and (iii) are expected to be recovered. Our contract assets consist of capitalized commission costs and upfront payments made to a customer. Based on the policy above, we capitalize a portion of our commission costs as an incremental cost of obtaining a contract. When calculating the incremental cost of obtaining a contract, we exclude any commission costs related to metrics that could be satisfied without obtaining a contract, including training-related metrics. We amortize our commission costs over a period of three years, which is consistent with the period over which the products and services related to the commission are transferred to the customer. The three-year period was determined based on our review of historical enhancements and upgrades to our products and services. We applied the portfolio approach to account for the amortization of contract costs for those contracts that have similar characteristics. Upfront payments made to a customer are capitalized and amortized over the expected period of benefit and are recorded as a reduction to revenue.

The current portion of capitalized commission costs and upfront payments made to customers are included in other current assets within our condensed consolidated balance sheets. The non-current portion of capitalized commission costs and upfront payments made to customers are reflected in other assets within our condensed consolidated balance sheets.

We review the capitalized costs for impairment at least annually. Impairment exists if the carrying amount of the asset recognized from contract costs exceeds the remaining amount of consideration we expect to receive in exchange for providing the goods and services to which such asset relates, less the costs that relate directly to providing those good and services and that have not been recognized as an expense. We did not record an impairment loss on our contract assets during the three and six months ended June 30, 2021 and 2020.

Contract Liabilities

Contract liabilities include payments received in advance of performance under the contract and are realized with the associated revenue recognized under the contract. All of the deferred revenue presented in the condensed consolidated balance sheets represents contract liabilities resulting from advance cash receipts from customers or amounts billed in advance to customers from the sale of services. Changes in deferred revenue are due to our performance under the contract as well as to cash received from new contracts for which services have not been provided.

Note 4. Accounts Receivable, Net

The components of accounts receivable, net are as follows (in thousands):

	June 30, 2021		December 31, 2020
Accounts receivable	$	97,529	$	89,502
Allowance for credit losses	(3,573)		(4,696)
Allowance for product returns	(1,344)		(1,480)
Accounts receivable, net	$	92,612	$	83,326

For the three and six months ended June 30, 2021, we recorded a provision for credit losses of $0.1 million and $0.2 million on our accounts receivable, respectively. For the three months ended June 30, 2020, we recorded a reduction to the provision for credit losses of $0.9 million on our accounts receivable. For the six months ended June 30, 2020, we recorded a provision for credit losses of $1.0 million on our accounts receivable.

For the three and six months ended June 30, 2021, we recorded a reserve for product returns of $0.5 million and $1.1 million, respectively, as compared to $0.7 million and $1.0 million for the same periods in the prior year. Historically, we have not experienced write-offs for uncollectible accounts or sales returns that have differed significantly from our estimates.

Allowance for Credit Losses - Accounts Receivable

The allowance for credit losses is a valuation account that is deducted from the accounts receivable and notes receivable amortized cost basis (see Note 8) to present the net amount expected to be collected. We estimate the allowance balance by applying the loss-rate method using relevant available information from internal and external sources, including historical write-off activity, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for changes in economic conditions, such as changes in unemployment rates. We use projected economic conditions over a period no more than twelve months based on data from external sources. For periods beyond the twelve-month reasonable and supportable forecast period, we revert to historical loss information immediately.

The allowance for credit losses is measured on a pooled basis when similar risk characteristics exist. When assessing whether to measure certain financial assets on a pooled basis, we considered various risk characteristics, including the financial asset type, size and the historical or expected credit loss pattern. We identified the following two portfolio segments for our accounts receivable: (i) outstanding accounts receivable balances within Alarm.com and certain subsidiaries and (ii) outstanding accounts receivable balances within all other subsidiaries. There were no changes to our portfolio segments for our accounts receivable during the three and six months ended June 30, 2021, and no changes to our policies or practices that influenced our estimate of expected credit losses for accounts receivable. There were no significant changes in the amount of accounts receivable write-offs during the three and six months ended June 30, 2021, as compared to historical periods other than a partial write-off of $0.7 million related to one of our distribution partners' outstanding balance during the six months ended June 30, 2021, upon the distributor being acquired by a third party.

Expected credit losses are estimated over the contractual term of the financial assets and we adjust the term for expected prepayments when appropriate. For the three and six months ended June 30, 2021, we recorded credit loss expense for accounts receivable and notes receivable of $0.1 million and less than $0.1 million, respectively, in general and administrative expense in our condensed consolidated statements of operations. For the three months ended June 30, 2020, we recorded a reduction of credit loss expense of $0.9 million and for the six months ended June 30, 2020, we recorded credit loss expense of $0.5 million in general and administrative expense in our condensed consolidated statements of operations. The contractual term excludes expected extensions, renewals and modifications because extension and renewal options are unconditionally cancelable by us. Write-offs of the amortized cost basis are recorded to the allowance for credit losses. Any subsequent recoveries of previously written off balances are recorded as a reduction to credit loss expense.

Note 6. Acquisitions

Asset Acquisitions

On March 12, 2020, Alarm.com Incorporated, one of our wholly-owned subsidiaries, acquired certain assets of an unrelated third party. Substantially all of the acquired assets consisted of in-process research and development, or IPR&D. We believe the acquisition of the IPR&D will continue to strengthen our smart intercom capability, including building access security and convenience within the multiple dwelling unit market for residents, guests and deliveries.

In consideration for the purchase of the IPR&D, we paid $1.2 million in cash on March 12, 2020, with the remaining $0.3 million expected to be paid 18 months following the acquisition date, subject to offset for any indemnification obligations. The $1.5 million consideration related to IPR&D was expensed at the time of the asset acquisition and was included in research and development expense in our condensed consolidated statements of operations during the six months ended June 30, 2020, as the IPR&D had no alternative future use.

On March 31, 2020, Alarm.com Incorporated acquired certain assets of an unrelated third party. Substantially all of the acquired assets consisted of IPR&D. We believe the acquisition of the IPR&D will continue to further our commitment to make significant investments in innovative research and development in the intelligently connected property market to broaden our suite of solutions.

In consideration for the purchase of the IPR&D, we paid $2.1 million in cash on March 31, 2020, $0.1 million in December 2019 and the remaining $0.7 million in April 2021. The $2.9 million consideration related to IPR&D was expensed at the time of the asset acquisition and was included in research and development expense in our condensed consolidated statements of operations during the six months ended June 30, 2020, as the IPR&D had no alternative future use.

Acquisition of a Business - Shooter Detection Systems

On December 14, 2020, Alarm.com Incorporated acquired 100% of the issued and outstanding ownership interest units of Shooter Detection Systems, LLC, or SDS. SDS provides an indoor gunshot detection solution through the Guardian Indoor Active Shooter Detection System, which uses a combination of acoustic and infrared sensors and proprietary algorithms to detect gunshots and communicate shooting incident details to building occupants and security teams. The acquisition of SDS expands our commercial solutions and helps our partners outfit commercial and enterprise customers with the indoor gunshot detection solution.

ALARM.COM HOLDINGS, INC.

Notes to the Condensed Consolidated Financial Statements (Unaudited) — (Continued)

In consideration for the purchase of 100% of the issued and outstanding ownership interest units of SDS, we paid $26.6 million in cash on December 14, 2020. Pursuant to the terms of the unit purchase agreement, following the preliminary determination of the working capital of SDS as of the closing date, the purchase price decreased by $0.1 million. The purchase price allocation was finalized during the second quarter of 2021, including the working capital adjustment, resulting in a measurement period adjustment to increase the purchase consideration by $0.1 million and to increase goodwill by $0.1 million.

The table below sets forth the purchase consideration and the fair value allocation of the tangible and intangible net assets acquired (in thousands):

	December 14, 2020
Calculation of Purchase Consideration:
Cash paid, net of working capital adjustment	$	26,577
Total consideration	$	26,577
Tangible and Intangible Net Assets:
Cash	$	311
Accounts receivable	1,179
Inventory	917
Other current assets	240
Property and equipment	77
Operating lease right-of-use assets	384
Other assets	348
Customer relationships	2,362
Developed technology	13,522
Trade name	512
Accounts payable	(19)
Accrued expenses	(111)
Operating lease current liabilities	(51)
Operating lease liabilities	(333)
Goodwill	7,239
Total tangible and intangible net assets	$	26,577

Goodwill of $7.2 million reflects the value of acquired workforce and synergies we expect to achieve from expanding our commercial solutions through SDS's indoor gunshot detection solution. The goodwill recognized is expected to be deductible for income tax purposes in future periods. We allocate goodwill to reporting units based on expected benefit from synergies and have allocated the goodwill to the Alarm.com segment.

Fair Value of Net Assets Acquired and Intangibles

In accordance with Accounting Standards Codification, or ASC, 805, Business Combinations, SDS constituted a business and the assets and liabilities were recorded at their respective fair values as of December 14, 2020. We developed our estimate of the fair value of intangible net assets using the with-and-without method for customer relationships, the multi-period excess earnings method for the developed technology and the relief-from-royalty method for the trade name.

Customer Relationships

We recorded the customer relationships intangible separately from goodwill based on determination of the length, strength and contractual nature of the relationship that SDS shared with its customers. We valued the single group of customer relationships using the with-and-without method, an income approach. The significant assumptions used in the with-and-without method include estimates about future expected cash flows from customer contracts and the discount rate. We are amortizing the customer relationships, valued at $2.4 million, on an attribution basis derived from the discounted cash flows of the model over an estimated useful life of six years.

Developed Technology

Developed technology primarily consists of intellectual property of proprietary software that is marketed for sale. We valued the developed technology by applying the multi-period excess earnings method, an income approach. The significant assumptions used in the multi-period excess earnings method include estimates about future expected cash flows from the developed technology, the obsolescence factor and the discount rate. We are amortizing the SDS developed technology, valued at $13.5 million, on an attribution method based on the discounted cash flows of the model over an estimated useful life of seven years.

Trade Name

We valued the trade names acquired using a relief from royalty method. The significant assumptions used in relief from royalty method include future expected cash flows from the trade name, the royalty rate and the discount rate. We are amortizing the trade names, valued at $0.5 million, on an attribution basis derived from the discounted cash flows of the model over an estimated useful life of five years.

Note 8. Other Assets

Purchases of Patents and Patent Licenses

From time to time, we enter into agreements to purchase patents or patent licenses. The carrying value, net of amortization, of our purchased patents and patent licenses was $2.5 million and $2.9 million as of June 30, 2021 and December 31, 2020, respectively. As of June 30, 2021 and December 31, 2020, $0.7 million of patent costs were included in other current assets and $1.8 million and $2.2 million of patent costs were included in other assets, respectively. We have $7.0 million of historical cost in purchased patents and patent licenses as of June 30, 2021. We are amortizing the patent costs over the estimated useful lives of the patents, which range from three years to eighteen years. Patent cost amortization of $0.1 million and $0.2 million was included in cost of SaaS and license revenue in our condensed consolidated statements of operations for the three and six months ended June 30, 2021 and 2020, respectively. Patent cost amortization of $0.1 million was included in amortization and depreciation in our condensed consolidated statements of operations for each of the three and six months ended June 30, 2021 and 2020.

Loan to a Distribution Partner

In September 2016, we entered into dealer and loan agreements with a distribution partner. The dealer agreement enables the distribution partner to resell our SaaS services and hardware to their subscribers. Under the loan agreements, we agreed to loan the distribution partner up to $4.0 million, collateralized by all assets owned by the distribution partner. The advance period for the loan was amended in August 2017 to begin each year on September 1 and end each year on December 31. Interest on the outstanding principal accrued at a rate per annum equal to the greater of 6.0% or LIBOR, plus 4.0%, as determined on the first date of each annual advance period. The repayment of principal and accrued interest was due in three installments beginning in July and ending in August following the advance period. The maturity date of the loan was August 31, 2019; however, the borrower had the option to extend the term of the loan for two successive terms of one year each.

In May 2018, the loan agreement with our distribution partner was amended to convert the entire $4.0 million note receivable outstanding into a $4.0 million term loan. The term loan had a maturity date of July 31, 2022 and required annual principal repayments of $1.0 million on July 31 of each year, commencing on July 31, 2019. The term loan also required monthly interest payments, with interest accruing on the outstanding principal balance at a rate per annum equal to 6.0% through June 30, 2018 and a rate per annum equal to the LIBOR rate on the first of any interest period plus 7.0% beginning on July 1, 2018.

ALARM.COM HOLDINGS, INC.

Notes to the Condensed Consolidated Financial Statements (Unaudited) — (Continued)

In April 2017, we entered into a subordinated credit agreement with an affiliated entity of the distribution partner and loaned the affiliated entity $3.0 million, with a maturity date of November 21, 2022. Interest on the outstanding principal balance accrued at a rate of 8.5% per annum and required monthly interest payments.

In June 2020, we amended the term loan with our distribution partner and also amended the subordinated credit agreement with the affiliated entity of the distribution partner. At the time of the amended term loan and subordinated credit agreement in June 2020, the outstanding balance of the term loan was $3.0 million and the outstanding balance of the subordinated credit agreement was $3.0 million. Under the amended terms, the distribution partner paid us $2.0 million in principal for the term loan on June 9, 2020 and the remaining $1.0 million was transferred to the amended subordinated credit agreement with the affiliated entity of the distribution partner.

The amended subordinated credit agreement with the affiliated entity of the distribution partner matures on September 9, 2025 and interest on the outstanding principal balance accrues at a rate of 9.0% per annum and is payable in kind. As of June 30, 2021 and December 31, 2020, $4.4 million and $4.2 million of the notes receivable balance related to the subordinated credit agreement was included in other assets in our condensed consolidated balance sheets, respectively.

For the three and six months ended June 30, 2021, we recognized $0.9 million and $1.6 million of revenue from the distribution partners associated with these loans, respectively, as compared to $0.9 million and $1.3 million for the same periods in the prior year.

Loans to Service Provider Partners

In July 2020, we entered into a loan agreement with a service provider partner, under which we agreed to loan the service provider partner up to $2.5 million, collateralized by the assets of the service provider partner. Interest on the outstanding principal accrues at a rate per annum equal to 9.0% and monthly interest and principal payments began in April 2021. The maturity date of the loan is July 24, 2025. As of each of June 30, 2021 and December 31, 2020, $1.2 million of principal was outstanding from the service provider partner under the loan agreement.

For the three and six months ended June 30, 2021 and 2020, we recognized less than $0.1 million and $0.1 million of revenue from the service provider partner associated with this loan, respectively.

Investment in a Hardware Supplier

In October 2018, we entered into a subordinate convertible promissory note with one of our hardware suppliers. In July 2019, we converted the outstanding notes receivable balance of $5.6 million into 9,520,832 shares of Series B preferred stock in the hardware supplier. We concluded that the $5.6 million equity investment, which is included in the Alarm.com segment, does not meet the criteria for consolidation and will be accounted for using the measurement alternative. Under the alternative, we measure investments without readily determinable fair values at cost, less impairment, adjusted for observable price changes from orderly transactions for identical or similar investments. As of June 30, 2021 and December 31, 2020, our investment in the hardware supplier was $5.6 million.

Investment in a Technology Partner

In December 2016, we paid $0.3 million for a convertible promissory note with a technology partner. In April 2018, the $0.3 million convertible promissory note converted into 135,135 shares of Series A-1 Preferred Stock. At the time of conversion, we determined there was no value related to the Series A-1 Preferred Stock. Based on observable price changes from orderly transactions for similar investments, we increased the amount of our investment by $0.7 million and recorded a gain within other income, net, in our consolidated statements of operations during the year ended December 31, 2020.

In February 2021, we paid $5.0 million in cash to purchase 1,000,000 shares of Series B-2 Preferred Stock from the same technology partner as part of a financing round that included other investors. The $5.0 million equity investment, which is included in the Alarm.com segment, does not meet the criteria for consolidation and is accounted for using the measurement alternative. Under the alternative, we measure investments without readily determinable fair values at cost, less impairment, adjusted for observable price changes from orderly transactions for identical or similar investments.

As of June 30, 2021 and December 31, 2020, our investment in the technology partner was $5.7 million and $0.7 million, respectively.

Allowance for Credit Losses - Notes Receivable

We identified the following two portfolio segments for our notes receivable: (i) loan receivables and (ii) hardware financing receivables. There were no changes to our portfolio segments for our notes receivable during the three and six months ended June 30, 2021, and no changes to our policies or practices involving the issuance of notes receivable, customer acquisitions or any other factors that influenced our estimate of expected credit losses for notes receivable.

We do not accrue interest on notes receivable that are considered impaired or are 90 days or greater past due based on their contractual payment terms. Notes receivable that are 90 days or greater past due are placed on nonaccrual status. Notes receivable may be placed on nonaccrual status earlier if, in management’s opinion, a timely collection of the full principal and interest becomes uncertain. After a note receivable has been placed on nonaccrual status, interest will be recognized when cash is received. A note receivable may be returned to accrual status after all of the customer’s delinquent balances of principal and interest have been settled, and collection of all remaining contractual amounts due is reasonably assured. We have elected not to measure an allowance for credit losses for accrued interest receivables. We write-off any accrued interest on notes receivable that are considered impaired or are 90 days or greater past due based on their contractual payment terms by reversing interest income. The accrued interest receivable as of each of June 30, 2021 and December 31, 2020 was less than $0.1 million, and is reflected in other current assets within our condensed consolidated balance sheets and excluded from the amortized cost basis of the notes receivable. We did not write-off any accrued interest receivable during the three and six months ended June 30, 2021 and 2020.

There were no purchases or sales of financial assets during the three and six months ended June 30, 2021 and 2020. There were no significant changes in the amount of note receivable write-offs during the three and six months ended June 30, 2021, as compared to historical periods.

The changes in our allowance for credit losses for notes receivable are as follows (in thousands):

Notes to the Condensed Consolidated Financial Statements (Unaudited) — (Continued)

During the three and six months ended June 30, 2021 and 2020, there was no interest income recognized related to notes receivables that were in nonaccrual status.

As of June 30, 2021 and December 31, 2020, there were no notes receivables placed in nonaccrual status for which there was not a related allowance for credit losses. As of June 30, 2021 and December 31, 2020, there were no notes receivables that were 90 days or greater past due for which we continued to accrue interest income.

Prepaid Expenses

As of June 30, 2021 and December 31, 2020, $12.0 million and $8.4 million of prepaid expenses were included in other current assets, respectively, primarily related to software licenses and for long lead-time parts related to our inventory.

End of period balance	$	—	$	306	$	—	$	306

The money market accounts are included in our cash and cash equivalents in our condensed consolidated balance sheets. Our money market assets are valued using quoted prices in active markets. See Note 12 for the carrying amount and estimated fair value of our convertible senior notes as of June 30, 2021.

The contingent consideration liability consisted of the potential earn-out payment related to our acquisition of 85% of the issued and outstanding capital stock of OpenEye on October 21, 2019. The earn-out payment was contingent on the satisfaction of certain calendar 2020 revenue targets and had a maximum potential payment of up to $11.0 million. During parts of 2019 and 2020, we accounted for the contingent consideration using fair value and established a liability for the future earn-out payment based on an estimation of revenue attributable to perpetual licenses and subscription licenses over the 2020 calendar year. The contingent consideration liability was valued with significant unobservable inputs, including the revenue volatility and the discount rate. Selecting another revenue volatility or discount rate within an acceptable range would not have resulted in a significant change to the fair value of the contingent consideration liability. As of October 21, 2019, the fair value of the liability was $2.8 million. At each reporting date until December 31, 2020, we remeasured the liability, using the same valuation approach. Changes in the fair value resulting from information that existed subsequent to the acquisition date were recorded in general and administrative expense in our condensed consolidated statements of operations. As of December 31, 2020, the 2020 revenue targets were not met and the fair value of the contingent consideration related to the potential earn-out payment decreased to zero as compared to the initial liability recorded at the acquisition date, primarily due to OpenEye's 2020 actual revenue being less than the projected revenue.

Notes to the Condensed Consolidated Financial Statements (Unaudited) — (Continued)

We monitor the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. There were no transfers in or out of Level 3 during the three and six months ended June 30, 2021 and 2020. We also monitor the value of the investments for other-than-temporary impairment on a quarterly basis. No other-than-temporary impairments occurred during the three and six months ended June 30, 2021 and 2020.

Note 10. Leases

We lease office space, data centers and office equipment under non-cancelable operating leases with various expiration dates through 2026. In August 2014, we signed a lease for office space in Tysons, Virginia, where we relocated our headquarters to in February 2016. We have subsequently entered into amendments to this lease from 2015 to 2020 to provide us with additional office space. The lease term ends in 2026, includes a five-year renewal option and a cumulative tenant improvement allowance of $11.8 million.

Supplemental information related to leases is presented in the table below (in thousands, except weighted-average term and discount rate):

(2)Imputed interest was calculated using the incremental borrowing rate applicable for each lease.

We did not have any finance leases or subleases as of June 30, 2021 or December 31, 2020. Our lease agreements do not contain any material residual value guarantees, restrictive covenants or variable lease payments. Short-term lease costs were immaterial for the three and six months ended June 30, 2021 and 2020.

Note 12. Debt, Commitments and Contingencies

The debt, commitments and contingencies described below would require us, or our subsidiaries, to make payments to third parties under certain circumstances.

Convertible Senior Notes

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026 in a private placement to qualified institutional buyers, or the 2026 Notes. The terms of the 2026 Notes are governed by an Indenture, or the Indenture, by and between Alarm.com Holdings, Inc. and U.S. Bank National Association, as trustee. The 2026 Notes are senior unsecured obligations that do not bear regular interest and the principal amount of the 2026 Notes will not accrete. The 2026 Notes may bear special interest under specified circumstances related to our failure to comply with our reporting obligations under the Indenture. Special interest, if any, will be payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2021. We received proceeds from the issuance of the 2026 Notes of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs.

We may not redeem the 2026 Notes prior to January 20, 2024. We may redeem for cash, all or any portion of the 2026 Notes, at our option, on or after January 20, 2024, at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date, if the last reported sale price of our common stock has been at least 130% of the conversion price for the 2026 Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. No sinking fund is provided for the 2026 Notes.

The 2026 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding August 15, 2025, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the 2026 Notes on each applicable trading day; (2) during the five business day period immediately after any 10 consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of 2026 Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the 2026 Notes on each such trading day; (3) if we call any or all of the 2026 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the 2026 Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events as set forth in the Indenture.

On or after August 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date of the 2026 Notes, holders of the 2026 Notes may convert all or any portion of their 2026 Notes at any time, regardless of the foregoing conditions. Upon conversion, we may satisfy our conversion obligation by paying or delivering, as the

Notes to the Condensed Consolidated Financial Statements (Unaudited) — (Continued)

case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. It is our current intent to settle the principal amount of the 2026 Notes with cash. The initial conversion rate for the 2026 Notes is 6.7939 shares of our common stock per $1,000 principal amount of 2026 Notes, which is equivalent to an initial conversion price of $147.19 per share of our common stock, subject to adjustment under certain circumstances in accordance with the terms of the Indenture. In addition, following certain corporate events that occur prior to the maturity date of the 2026 Notes or if we deliver a notice of redemption in respect of the 2026 Notes, we will, under certain circumstances, increase the conversion rate of the 2026 Notes for a holder who elects to convert its 2026 Notes (or any portion thereof) in connection with such a corporate event or convert its 2026 Notes called (or deemed called) for redemption during the related redemption period (as defined in the Indenture), as the case may be.

If we undergo a fundamental change (as defined in the Indenture), subject to certain exceptions and except as described in the Indenture, holders may require us to repurchase for cash all or any portion of their 2026 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.

The Indenture includes customary covenants and sets forth certain events of default after which the 2026 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving us after which the 2026 Notes become automatically due and payable.

We used some of the proceeds to repay the $110.0 million outstanding principal balance under our credit facility and also used some of the proceeds to pay accrued interest, fees and expenses related to our credit facility (see the section titled "2017 Facility" below). We are using the remaining net proceeds from the issuance of the 2026 Notes for working capital and other general corporate purposes, which may include acquisitions or strategic investments in complementary businesses or technologies.

In accounting for the transaction, the 2026 Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2026 Notes. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the contractual term of the 2026 Notes at an effective interest rate of 4.0%.

In accounting for the debt issuance costs of $15.7 million related to the 2026 Notes, we allocated the total amount incurred to the liability and equity components of the 2026 Notes based on their relative values. Issuance costs attributable to the liability component were $13.3 million and will be amortized to interest expense using the effective interest method over the contractual term of the 2026 Notes. Issuance costs attributable to the equity component were netted with the equity component in additional paid-in capital.

As of June 30, 2021, the fair value of our 2026 Notes was $467.1 million. The fair value was determined based on the quoted price of the 2026 Notes in an inactive market on the last traded day of the quarter and has been classified as Level 2 in the fair value hierarchy. Based on the closing price of our common stock of $84.70 on the last trading day of the quarter, the if-converted value of the 2026 Notes did not exceed the principal amount of $500.0 million as of June 30, 2021.

The net carrying amount of the liability component of the 2026 Notes is as follows (in thousands):

	June 30, 2021		December 31, 2020
Principal	$	500,000	$	—
Unamortized debt discount	(70,794)		—

The net carrying amount of the equity component of the 2026 Notes is as follows (in thousands):

Debt discount for conversion option	$	77,199	$	—
Debt issuance costs	(2,424)		—

Amortization of debt issuance costs	557		—		989		—
Total interest expense	$	4,149	$	—	$	7,393	$	—

The difference between the book and tax treatment of the debt discount and debt issuance costs of the 2026 Notes resulted in a difference between the carrying amount and tax basis of the 2026 Notes. This taxable temporary difference resulted in the recognition of a $18.3 million net deferred tax liability which was recorded as an adjustment to additional paid-in capital during the three months ended March 31, 2021.

2017 Facility

On October 6, 2017, we entered into a $125.0 million senior secured revolving credit facility, or the 2017 Facility, with Silicon Valley Bank, or SVB, as administrative agent, PNC Bank, National Association, as documentation agent, and a syndicate of lenders. Upon entry into the 2017 Facility, we borrowed $72.0 million, which was used to repay the previously outstanding balance under our previous credit facility. The 2017 Facility was set to mature in October 2022 and included an option to further increase the borrowing capacity to $175.0 million with the consent of the lenders. Costs incurred in connection with the 2017 Facility were capitalized and were being amortized as interest expense over the term of the 2017 Facility. The 2017 Facility was secured by substantially all of our assets, including our intellectual property. On March 25, 2020, we borrowed $50.0 million under the 2017 Facility as a precautionary measure in order to provide financial flexibility in light of current uncertainty in the financial markets resulting from the COVID-19 pandemic. On January 20, 2021, we repaid the entire outstanding principal balance of $110.0 million of the 2017 Facility with proceeds from the 2026 Notes. The 2017 Facility was terminated on January 20, 2021 and we recognized an extinguishment loss of $0.2 million in other income / (expense), net in our condensed consolidated statements of operations during the six months ended June 30, 2021 for previously capitalized debt issuance costs related to the 2017 Facility that were unamortized at the time of the termination of the 2017 Facility.

The outstanding principal balance on the 2017 Facility accrued interest at a rate equal to, at our option, either (1) LIBOR, plus an applicable margin based on our consolidated leverage ratio, or (2) the highest of (a) the Wall Street Journal prime rate, (b) the Federal Funds rate plus 0.50%, or (c) LIBOR plus 1.00% plus an applicable margin based on our consolidated leverage ratio. During 2021 until the termination of the 2017 Facility on January 20, 2021, we elected for the outstanding principal balance to accrue interest at LIBOR plus 1.50%, LIBOR plus 1.75%, LIBOR plus 2.00%, and LIBOR plus 2.50% when our consolidated leverage ratio is less than 1.00:1.00, greater than or equal to 1.00:1.00 but less than 2.00:1.00, greater than or equal to 2.00:1.00 but less than 3.00:1.00 and greater than or equal to 3.00:1.00, respectively. The 2017 Facility also carried an unused line commitment fee of 0.20%. For the six months ended June 30, 2020, the effective interest rate on the 2017 Facility was 3.42%.

The carrying value of the 2017 Facility was zero and $110.0 million as of June 30, 2021 and December 31, 2020, respectively. The 2017 Facility included a variable interest rate that approximated market rates and, as such, we classified the liability as Level 2 within the fair value hierarchy and determined that the carrying amount of the 2017 Facility approximated its fair value as of December 31, 2020.

Commitments and Contingencies

Contingent Consideration

On October 21, 2019, we acquired 85% of the issued and outstanding capital stock of OpenEye. Certain stockholders of OpenEye had the right to receive an earn-out payment of up to an additional $11.0 million based upon satisfaction of certain calendar 2020 revenue targets. At October 21, 2019, the fair value of the contingent consideration liability was $2.8 million. At each reporting date until December 31, 2020, we remeasured the liability, using the same valuation approach. Changes in the fair value resulting from information that existed subsequent to the acquisition date were recorded in the condensed consolidated statements of operations. As of December 31, 2020, the 2020 revenue targets were not met and the fair value of the contingent consideration related to the potential earn-out payment decreased to zero as compared to the initial liability recorded at the acquisition date, primarily due to OpenEye's 2020 actual revenue being less than the projected revenue (see Note 9).

Indemnification Agreements

We have various agreements that may obligate us to indemnify the other party to the agreement with respect to certain matters. Generally, these indemnification provisions are included in contracts arising in the normal course of business. Although we cannot predict the maximum potential amount of future payments that may become due under these indemnification agreements, we do not believe any potential liability that might arise from such indemnity provisions is probable or material.

Legal Proceedings

On June 2, 2015, Vivint, Inc., or Vivint, filed a lawsuit against us in U.S. District Court, District of Utah, alleging that our technology directly and indirectly infringes six patents that Vivint purchased. Vivint is seeking permanent injunctions, enhanced damages and attorneys' fees. We answered the complaint on July 23, 2015. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. On August 19, 2016, the U.S. District Court, District of Utah stayed the litigation pending inter partes review by the U.S. Patent Trial and Appeal Board, or PTAB, of five of the patents in suit. In March 2017, the PTAB issued final written decisions relating to two patents finding all challenged claims unpatentable. In May 2017, the PTAB issued final written decisions relating to the remaining three patents that found certain claims unpatentable, while certain other claims were not found to be unpatentable. Vivint appealed the decisions to the U.S. Court of Appeals for the Federal Circuit, or the Federal Circuit, and we cross-appealed. In July 2018, the Federal Circuit issued orders affirming the PTAB’s March 2017 decisions that invalidated all challenged claims of two patents. The U.S. District Court, District of Utah lifted the stay on the litigation on June 26, 2017, with Vivint proceeding with its case on four of the six patents in its complaint. No trial date has been set. In September 2017, the U.S. Patent and Trademark Office, or PTO, ordered ex parte reexaminations of certain claims of two of the remaining patents in suit, at our request. On October 30, 2018 and November 5, 2018, the PTO issued final office actions in the pending reexaminations rejecting all claims being examined as unpatentable over the prior art. Nine claims asserted in the litigation were found unpatentable in the PTO rejections. Vivint appealed these rejections to the PTAB on March 29, 2019 and April 4, 2019. The PTAB issued decisions affirming the rejections on February 28, 2020 and May 4, 2020. Vivint appealed these decisions to the Federal Circuit on July 1, 2020 and April 26, 2021. On December 20, 2018, the Federal Circuit issued an order regarding the inter partes review of three of the remaining patents in suit that vacated, reversed and remanded the PTAB’s ruling with regard to the construction of a term (“communication device identification code”) as requested by Alarm.com and affirmed the PTAB’s May 2017 rulings invalidating certain of the Vivint patents in all other respects. On July 24, 2019, the PTAB issued further decisions with respect to two of the remaining patents in suit, finding additional claims unpatentable in view of the Federal Circuit’s December 20, 2018 decision. One of the claims asserted in the litigation was found unpatentable in the July 14, 2019 decisions. Vivint appealed the July 24, 2019 decisions to the Federal Circuit on September 25, 2019. On April 13, 2021, the Federal Circuit affirmed the PTAB decisions. On February 12, 2021, we filed an action in U.S. District Court, Eastern District of Virginia challenging the refusal by the PTO to proceed with additional reexaminations of the remaining patent claims asserted in the lawsuit. The U.S. District Court, Eastern District of Virginia granted the PTO’s motion to dismiss the case for lack of jurisdiction on June 22, 2021. We appealed the dismissal to the Federal Circuit on June 24, 2021.

Should Vivint prevail in proving Alarm.com infringes one or more of its patent claims, we could be required to pay damages of Vivint’s lost profits and/or a reasonable royalty for sales of our solution. Since all remaining patent claims in the litigation have expired, Vivint shall not be entitled to injunctive relief as a remedy in this matter. While we believe we have valid defenses to Vivint’s claims, any of these outcomes could result in a material adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

On October 22, 2019, EcoFactor, Inc., or EcoFactor, filed a complaint with the U.S. International Trade Commission, or ITC, naming Alarm.com Incorporated and Alarm.com Holdings, Inc., among others, as proposed respondents. The complaint alleges that Alarm.com’s smart thermostats infringe three U.S. patents owned by EcoFactor. EcoFactor is seeking a permanent limited exclusion order and permanent cease and desist order. On November 22, 2019, the ITC instituted an investigation into EcoFactor’s allegations naming Alarm.com Incorporated, Alarm.com Holdings, Inc. and others as respondents. We answered the complaint on December 19, 2019. Among other things, we asserted defenses based on non-infringement and invalidity of the

patents in question. An evidentiary hearing was held in November 2020. On April 20, 2021, the administrative law judge presiding over the investigation issued a final initial determination finding in favor of Alarm.com. On July 20, 2021, the ITC commissioners issued a decision affirming the ruling in favor of Alarm.com and terminated the investigation.

On November 11, 2019, EcoFactor filed a lawsuit against us in U.S. District Court, District of Massachusetts, alleging infringement of the same three patents asserted against us in the ITC. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. On December 26, 2019, the court issued an order staying the lawsuit pending the conclusion of the related ITC investigation.

On May 26, 2020, EcoFactor filed a second lawsuit against us in U.S. District Court, District of Massachusetts, alleging Alarm.com’s products and services infringe four additional U.S. patents owned by EcoFactor. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. On March 9, 2021, the PTO ordered ex parte reexamination of one of the patents asserted in the lawsuit, at Alarm.com’s request. On May 10, 2021, the PTAB instituted inter partes review of the same patent and subsequently stayed the ex parte reexamination pending the conclusion of its review. On May 13, 2021, the court issued an order staying the lawsuit until September 3, 2021 in light of the related ITC investigation.

Should EcoFactor prevail in its district court lawsuits we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to EcoFactor’s claims, the outcome of these legal claims cannot be predicted with certainty and any of these outcomes could result in an adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

On July 22, 2021, Causam Enterprises, Inc., or Causam, filed a lawsuit against us in U.S. District Court, Western District of Texas, alleging that Alarm.com’s smart thermostats infringe four U.S. patents owned by Causam. Causam is seeking preliminary and permanent injunctions, enhanced damages and attorneys’ fees. Our response is due on September 13, 2021.

On July 28, 2021, Causam filed a complaint with the ITC naming Alarm.com Incorporated, Alarm.com Holdings, Inc., and EnergyHub, Inc., among others, as proposed respondents. The complaint alleges infringement of the same four patents Causam asserted in district court. Causam is seeking a permanent limited exclusion order and permanent cease and desist order. The ITC has not yet instituted an investigation into the allegations.

Should Causam prevail in an ITC investigation, Alarm.com thermostats manufactured abroad could be excluded from importation into the United States. Should Causam prevail in its district court lawsuit we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to Causam’s claims, the outcome of these legal claims cannot be predicted with certainty, and any of these outcomes could result in an adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

In addition to the matters described above, we may be required to provide indemnification to certain of our service provider partners for certain claims regarding our solutions. For example, we are incurring costs associated with the indemnification of our service provider ADT, LLC in ongoing patent infringement suits.

On July 13, 2016, Applied Capital, Inc., or Applied Capital, filed a lawsuit against ADT, LLC, the ADT Corporation, and Icontrol Networks, Inc. in U.S. District Court, the District of New Mexico.  Applied Capital, Inc v. The ADT Corporation et al., D. New Mexico Case No. 1-16-cv-00815. Icontrol was dismissed without prejudice on May 22, 2017.  Applied Capital alleges that ADT’s sales of ADT Pulse directly and indirectly infringes U.S. Patent Nos. 8,378,817 and 9,728,082, which were allegedly purchased by Applied Capital. Applied Capital is seeking damages and attorneys’ fees.  ADT answered Applied Capital’s amended complaint on July 16, 2018. Among other things, ADT has asserted defenses based on non-infringement and invalidity of the patents-in-suit. On April 5, 2019, Applied Capital filed a lawsuit for breach of contract against Rodney Fox, the inventor of the patents-in-suit, in the Second Judicial District Court, County of Bernalillo in New Mexico State Court (No. D-202-CV-2019-02841). Mr. Fox counterclaimed, alleging that he is the rightful owner of the patents-in-suit. Based on the dispute of ownership, on October 15, 2019, ADT filed a motion to stay in this matter pending its resolution. Applied Capital and Mr. Fox reached settlement and stipulated to dismissal of the New Mexico State Court action on October 31, 2019. Applied Capital filed its Second Amended Complaint on January 27, 2020 and ADT answered, adding a claim of inequitable conduct, on February 10, 2020. The court issued its claim construction order on August 12, 2019, fact discovery closed on November 12, 2019, expert discovery closed on March 9, 2020, and summary judgment and Daubert motions briefing closed on June 3, 2020. The parties reached settlement and the court dismissed the case on May 27, 2021.

On February 25, 2021, Vivint filed a lawsuit against ADT LLC a/k/a ADT LLC of Delaware d/b/a ADT Security Services in U.S. District Court, District of Utah, alleging that ADT Pulse, Control, and Blue each infringe one or more of six patents owned by Vivint. Vivint is seeking damages and attorneys’ fees. Vivint filed an amended complaint on March 24, 2021. ADT answered the amended complaint on April 30, 2021 and asserted defenses based on non-infringement and invalidity of all the patents in question, and inequitable conduct as to one of the patents. On June 25, 2021, ADT filed a motion for judgment on the pleadings seeking judgment in its favor as to five of the six asserted patents on the grounds that the claimed inventions are directed to ineligible subject matter.

Should Vivint prevail on the claims that one or more elements of ADT’s products infringe, we could be required to indemnify ADT for damages in the form of a reasonable royalty or ADT could be enjoined from making, using and selling our solution if a license or other right to continue selling our technology is not made available or we are unable to design around such patents, and required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. The outcome of these legal claims cannot be predicted with certainty. We believe there are valid defenses to the claims made by Vivint. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

We may also be a party to litigation and subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business.

Other than the preceding matters, we are not a party to any lawsuit or proceeding that, in the opinion of management, is reasonably possible or probable of having a material adverse effect on our financial position, results of operations or cash flows. We reserve for contingent liabilities based on ASC 450, "Contingencies," when it is determined that a liability, inclusive of defense costs, is probable and reasonably estimable. Litigation is subject to many factors that are difficult to predict, so there can be no assurance that, in the event of a material unfavorable result in one or more claims, we will not incur material costs.

Note 15. Earnings Per Share

Basic and Diluted Earnings Per Share

The components of basic and diluted earnings per share are as follows (in thousands, except share and per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Net income	$	14,490	$	16,625	$	29,040	$	25,196

Net income attributable to common stockholders (A)	$	14,745	$	16,995	$	29,575	$	25,802
Weighted average common shares outstanding — basic (B)	49,808,969		48,792,280		49,686,110		48,758,922
Dilutive effect of stock options and restricted stock units	1,945,423		1,759,352		2,103,833		1,684,604
Weighted average common shares outstanding — diluted (C)	51,754,392		50,551,632		51,789,943		50,443,526
Net income per share:
Basic (A/B)	$	0.30	$	0.35	$	0.60	$	0.53
Diluted (A/C)	$	0.28	$	0.34	$	0.57	$	0.51

The following securities have been excluded from the calculation of diluted weighted average common shares outstanding as the inclusion of these securities would have an anti-dilutive effect:

	Three Months Ended June 30,		Six Months Ended June 30,
	2021	2020	2021	2020
Stock options	133,700	360,032	133,700	360,032
Restricted stock units	149,291	12,965	123,091	105,015

Our redeemable noncontrolling interest relates to our 85% equity ownership interest in OpenEye. The OpenEye stockholder agreement contains a put option that gives the minority OpenEye stockholders the right to sell their OpenEye shares to us based on the fair value of the shares. The OpenEye stockholder agreement also contains a call option that gives us the right to purchase the remaining OpenEye shares from the minority OpenEye stockholders based on the fair value of the shares. The put and call options can each be exercised beginning in the first quarter of 2023. This redeemable noncontrolling interest is considered temporary equity and we report it between liabilities and stockholders’ equity in the condensed consolidated balance sheets. The amount of the net income or loss attributable to redeemable noncontrolling interests is recorded in the condensed consolidated statements of operations.

Since we expect to settle the principal amount on our outstanding 2026 Notes in cash and any excess in cash or shares of our common stock, we use the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The conversion spread has a dilutive impact on diluted net income per share of common stock when the average market price of our common stock for a given period exceeds the conversion price of $147.19 per share for the 2026 Notes. Based on the initial conversion price and the average market price of our common stock for the three and six months ended June 30, 2021, there was no dilutive effect of the 2026 Notes on our earnings per share during the three and six months ended June 30, 2021.

Note 16. Significant Service Providers

During the three and six months ended June 30, 2021, our 10 largest revenue service provider partners accounted for 48% and 49% of our consolidated revenue, respectively, as compared to 46% and 48% for the same periods in the prior year. One of our service provider partners within the Alarm.com segment individually represented greater than 10% but not more than 15% of our revenue for each of the three and six months ended June 30, 2021. One of our service provider partners within the Alarm.com segment individually represented greater than 15% but not more than 20% of our revenue for each of the three and six months ended June 30, 2020.

ALARM.COM HOLDINGS, INC.

Notes to the Condensed Consolidated Financial Statements (Unaudited) — (Continued)

One service provider partner in the Alarm.com segment represented more than 10% of accounts receivable as of June 30, 2021. Two service provider partners in the Alarm.com segment represented more than 10% of accounts receivable as of December 31, 2020.

Note 17. Income Taxes

For purposes of interim reporting, our annual effective income tax rate is estimated in accordance with ASC 740-270, "Interim Reporting." This rate is applied to the pre-tax book income of the entities expected to be benefited during the year. Discrete items that impact the tax provision are recorded in the period incurred.

For the three and six months ended June 30, 2021, we recorded a benefit from income taxes of $1.7 million and $4.7 million, respectively, resulting in an effective income tax rate of (13.6)% and (19.1)% for those periods. For the three and six months ended June 30, 2020, we recorded a benefit from income taxes of $2.3 million and $1.1 million, respectively, resulting in an effective income tax rate of (15.9)% and (4.5)% for those periods. Our effective tax rates were below the statutory rate primarily due to research and development tax credits claimed, tax windfall benefits from employee stock-based payment transactions and foreign derived intangible income deductions, partially offset by the impact of state taxes, foreign withholding taxes and other nondeductible expenses.

We recognize a valuation allowance if, based on the weight of available evidence, both positive and negative, it is more likely than not that some portion, or all, of net deferred tax assets will not be realized. Due to the uncertainty of realization of certain deferred tax assets acquired in 2017 related to our Canadian net operating losses and research and development tax credits, we established a valuation allowance of $0.3 million during the second quarter of 2019, which remained at $0.3 million as of June 30, 2021 and December 31, 2020. During 2020, we established a valuation allowance of $1.3 million for state research and development tax credit carryforwards, which remained at $1.3 million as of June 30, 2021 and December 31, 2020.

We apply guidance for uncertainty in income taxes that requires the application of a more likely than not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, this guidance permits us to recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is more likely than not to be realized upon settlement. We recorded an increase to the unrecognized tax benefits of $1.5 million primarily for research and development tax credits claimed during the six months ended June 30, 2021. We recorded unrecognized tax benefits of $1.9 million for research and development tax credits claimed during the six months ended June 30, 2020.

As of June 30, 2021 and December 31, 2020, we accrued $0.1 million of total interest expense related to unrecognized tax benefits. We recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Note 18. Segment Information

We have two reportable segments:

•Alarm.com segment

•Other segment

Our chief operating decision maker is our chief executive officer. Management determined the operational data used by the chief operating decision maker is that of the two reportable segments. Management bases strategic goals and decisions on these segments and the data presented below is used to measure financial results.

Our Alarm.com segment represents our cloud-based and Software platforms for the intelligently connected property and related solutions that contributed 95% of our revenue for each of the three and six months ended June 30, 2021, as compared to 94% for the same periods in the prior year.

Note 19. Related Party Transactions

Installation Partner

Our installation partner in which we have a 48.2% ownership interest performs installation services for security service providers and also provides installation services for us and certain of our subsidiaries. We account for this investment using the equity method. As of June 30, 2021 and December 31, 2020, our investment balance in our installation partner was zero. During the three and six months ended June 30, 2021 and 2020, we recorded $0.1 million and $0.2 million of cost of hardware and other revenue in connection with this installation partner, respectively. As of June 30, 2021 and December 31, 2020, the accounts payable balance to our installation partner was less than $0.1 million.

Overview

Alarm.com is the leading platform for the intelligently connected property. We offer a comprehensive suite of cloud-based solutions for smart residential and commercial properties, including interactive security, video monitoring, intelligent automation, energy management and wellness solutions. Millions of property owners depend on our technology to intelligently secure, automate and manage their residential and commercial properties. In the last year alone, our platforms processed more than 200 billion data points generated by over 100 million connected devices. We believe that this scale of subscribers, connected devices and data operations makes us the leader in the connected property market.

Our solutions are delivered through an established network of over 10,000 trusted service providers, who are experts at selling, installing and supporting our solutions. We primarily generate SaaS and license revenue through our service provider partners, who resell these services and pay us monthly fees. These service provider contracts typically have an initial term of one year, with subsequent renewal terms of one year. Our service provider partners have indicated that they typically have three to five-year service contracts with residential and commercial property owners who use our solutions. We also generate hardware and other revenue, primarily from our service provider partners and distributors. Our hardware sales include connected devices that enable our services, such as video cameras, video recorders, gunshot detection sensors, gateway modules and smart thermostats. We believe that the length of our service relationships with residential and commercial property owners, combined with our robust platforms and over 20 years of operating experience, contribute to a compelling business model.

Our solutions are designed to make both residential and commercial properties safer, smarter and more efficient. Our technology platforms support all participants in what we refer to as the connected property market. This market includes the residential and commercial property owners who subscribe to our services, the hardware partners who manufacture devices that integrate with our platforms and the service provider partners who install and maintain our solutions.

The Alarm.com platform enables our service provider partners to deploy our interactive security, video monitoring, intelligent automation, energy management and wellness solutions as stand-alone offerings or as combined solutions to address the needs of a broad range of customers.

Highlights of Second Quarter Results

We primarily generate SaaS and license revenue, our largest source of revenue, through our service provider partners who resell our services and pay us monthly fees. Our service provider partners sell, install and support Alarm.com solutions that enable residential and commercial property owners to intelligently secure, connect, control and automate their properties. Our subscribers consist of all of the properties maintained by those residential and commercial property owners to which we are delivering at least one of our solutions. We derive a portion of our revenue from licensing our intellectual property to third parties on a per customer basis. SaaS and license revenue represented 60% and 61% of our revenue during the three and six months ended June 30, 2021, respectively, as compared to 68% and 64% in the same periods in the prior year.

32

We also generate SaaS and license revenue from monthly fees charged to service providers on a per subscriber basis for access to our non-hosted software platform, or Software platform. The non-hosted software for interactive security, automation and related solutions is typically deployed and operated by the service provider in its own network operations center. Software license revenue represented 4% and 5% of our revenue during the three and six months ended June 30, 2021, respectively, as compared to 7% for the same periods in the prior year.

We also generate revenue from the sale of many types of hardware, including video cameras, video recorders, cellular radio modules, thermostats, image sensors, gunshot detection sensors and other peripherals, that enable our solutions. Our hardware and other revenue also includes our revenue from the sale of perpetual licenses that provide our customers in the commercial market the right to use our video surveillance software for an indefinite period of time in exchange for a one-time license fee. Our hardware and other revenue also includes our revenue from the sale of licenses that provide our customers the right to use our gunshot detection solution in exchange for license fees. Hardware and other revenue represented 40% and 39% of our revenue during the three and six months ended June 30, 2021, respectively, as compared to 32% and 36% in the same periods in the prior year. We typically expect hardware and other revenue to fluctuate as a percentage of total revenue.

Highlights of our financial performance for the periods covered in this Quarterly Report include:

•SaaS and license revenue increased 18% to $113.2 million in the three months ended June 30, 2021 from $95.7 million in the three months ended June 30, 2020. SaaS and license revenue increased 18% to $220.6 million in the six months ended June 30, 2021 from $187.7 million in the six months ended June 30, 2020. Included in SaaS and license revenue was software license revenue, which decreased to $8.3 million in the three months ended June 30, 2021 from $9.8 million in the three months ended June 30, 2020. Included in SaaS and license revenue was software license revenue, which decreased to $17.0 million in the six months ended June 30, 2021 from $19.5 million in the six months ended June 30, 2020.

•Total revenue increased 33% to $188.9 million in the three months ended June 30, 2021 from $141.6 million in the three months ended June 30, 2020. Total revenue increased 23% to $361.4 million in the six months ended June 30, 2021 from $293.6 million in the six months ended June 30, 2020.

•Net income decreased to $14.5 million in the three months ended June 30, 2021, as compared to $16.6 million in the three months ended June 30, 2020. Net income increased to $29.0 million in the six months ended June 30, 2021, as compared to $25.2 million in the six months ended June 30, 2020. Net income attributable to common stockholders decreased to $14.7 million in the three months ended June 30, 2021, as compared to $17.0 million in the three months ended June 30, 2020. Net income attributable to common stockholders increased to $29.6 million in the six months ended June 30, 2021, as compared to $25.8 million in the six months ended June 30, 2020.

•Adjusted EBITDA, a non-GAAP measurement of operating performance, increased to $38.0 million in the three months ended June 30, 2021 from $29.2 million in the three months ended June 30, 2020. Adjusted EBITDA increased to $73.6 million in the six months ended June 30, 2021 from $58.4 million in the six months ended June 30, 2020.

Please see Non-GAAP Measures below in this section of this Quarterly Report for a discussion of the limitations of Adjusted EBITDA (a non-GAAP measure) and a reconciliation of Adjusted EBITDA to net income, the most comparable measurement in accordance with accounting principles generally accepted in the United States, or GAAP, for the three and six months ended June 30, 2021 and 2020.

Recent Developments

The COVID-19 pandemic disrupted and may continue to disrupt our supply chain for an unknown period of time due to its impact on manufacturing, production and global transportation. The COVID-19 pandemic also disrupted and may intermittently continue to disrupt our sales channels due to restrictions on our service providers’ ability to meet with residential and commercial property owners who use our solutions. We have taken precautionary measures intended to help protect our employees, service providers and subscribers, as well as the communities in which we participate, including enabling substantially all of our employees to work remotely. In addition, the COVID-19 pandemic resulted in a global slowdown of economic activity and a recession in the United States and the economic situation remains fluid as parts of the economy appear to be recovering while others continue to struggle. While vaccines have been approved for use in the United States and in many other countries, and vaccination efforts are underway, it remains difficult to assess or predict the ultimate duration and economic impact of the COVID-19 pandemic. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results that can be expected for our entire fiscal year ending December 31, 2021, which is increasingly true in periods of extreme uncertainty, such as the uncertainty caused by the COVID-19 pandemic. Prolonged uncertainty with respect to COVID-19 could cause further economic slowdown or cause other unpredictable events, each of which could adversely affect our business, results of operations or financial condition.

While our business and those of our service providers showed some resiliency beginning in 2020 and continuing into 2021, if the economy fails to fully recover or there are additional shutdowns of non-essential businesses due to a resurgence of COVID-19 and the emergence and severity of COVID-19 variants, our SaaS and license revenue growth rate may be lower in future periods, with a corresponding reduction in hardware revenue, if some consumers or small businesses defer or cancel

33

previously anticipated purchases. The challenges posed by COVID-19 on our business continue to evolve rapidly and we will continue to evaluate our business and operations in light of future developments.

Other Business Metrics

We regularly monitor a number of financial and operating metrics in order to measure our current performance and estimate our future performance. Our other business metrics may be calculated in a manner different from the way similar business metrics used by other companies are calculated and include the following (dollars in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2021			2020			2021		2020
SaaS and license revenue	$	113,186		$	95,704		$	220,569	$	187,654
Adjusted EBITDA	38,006			29,210			73,612		58,399
	Twelve Months Ended June 30,
	2021			2020
SaaS and license revenue renewal rate	95		%	94		%

SaaS and License Revenue

SaaS and license revenue is a GAAP measure that we use to measure our current performance and estimate our future performance. We believe that SaaS and license revenue is an indicator of the productivity of our existing service provider partners and their ability to activate and maintain subscribers using our intelligently connected property solutions, our ability to add new service provider partners reselling our solutions, the demand for our intelligently connected property solutions and the pace at which the market for these solutions is growing.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP measure that represents our net income before interest expense, interest income, other income / (expense), net, benefit from income taxes, amortization and depreciation expense, stock-based compensation expense, secondary offering expense, acquisition-related (benefit) / expense and legal costs and settlement fees incurred in connection with non-ordinary course litigation and other disputes, particularly costs involved in ongoing intellectual property litigation. We do not consider these items to be indicative of our core operating performance. The non-cash items include amortization and depreciation expense, amortization of debt discount and debt issuance costs for the January 20, 2021 issuance of $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026, or the 2026 Notes, included in interest expense, and stock-based compensation expense related to stock options and other forms of equity compensation, including, but not limited to, the sale of common stock. We do not adjust for ordinary course legal expenses resulting from maintaining and enforcing our intellectual property portfolio and license agreements.

Adjusted EBITDA is a key measure that our management uses to understand and evaluate our core operating performance and trends to generate future operating plans, to make strategic decisions regarding the allocation of capital, and to make investments in initiatives that are focused on cultivating new markets for our solutions. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA facilitates comparisons of our operating performance on a period-to-period basis and, in the case of exclusion of acquisition-related adjustments and certain historical legal expenses, excludes items that we do not consider to be indicative of our core operating performance. Adjusted EBITDA is not a measure calculated in accordance with GAAP and should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Please see Non-GAAP Measures in this section for a discussion of the limitations of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, the most comparable GAAP measurement, for the three and six months ended June 30, 2021 and 2020.

SaaS and License Revenue Renewal Rate

Our SaaS and license revenue renewal rate is an operating metric. We measure our SaaS and license revenue renewal rate on a trailing 12-month basis by dividing (a) the total SaaS and license revenue recognized during the trailing 12-month period from our subscribers on our Alarm.com platform who were subscribers on the first day of the period, by (b) total SaaS and license revenue we would have recognized during the period from those same subscribers assuming no terminations, or service level upgrades or downgrades. The SaaS and license revenue renewal rate represents both residential and commercial properties. Our SaaS and license revenue renewal rate is expressed as an annualized percentage and it is calculated across our entire subscriber base on the Alarm.com platform excluding subscribers of service providers that may use one of our other platforms as a substitute for the Alarm.com platform. Our service provider partners, who resell our services to our subscribers, have indicated that they typically have three to five-year service contracts with our subscribers. Our SaaS and license revenue

34

renewal rate is calculated across our entire subscriber base on the Alarm.com platform, including subscribers whose contract with their service provider reached the end of its contractual term during the measurement period, as well as subscribers whose contract with their service provider has not reached the end of its contractual term during the measurement period, and is not intended to estimate the rate at which our subscribers renew their contracts with our service provider partners. We believe that our SaaS and license revenue renewal rate allows us to measure our ability to retain and grow our SaaS and license revenue and serves as an indicator of the lifetime value of our subscriber base.

Components of Operating Results

Our fiscal year ends on December 31. The key elements of our operating results include:

Revenue

We derive our revenue from three primary sources: the sale of cloud-based SaaS services on our integrated Alarm.com platform, the sale of licenses and services on the Software platform and the sale of hardware products. We sell our platform and hardware solutions to service provider partners that resell our solutions and hardware to residential and commercial property owners, who are the service provider partners’ customers.

SaaS and License Revenue. We generate the majority of our SaaS and license revenue primarily from monthly fees charged to our service provider partners on a per subscriber basis for access to our cloud-based intelligently connected property platform and related solutions. Our fees per subscriber vary based upon the service plan and features utilized.

We offer multiple service level packages for our platform solutions including a range of solutions and a range of a la carte add-ons for additional features. The fee paid by our service provider partners each month for the delivery of our solutions is based on the combination of packages and add-ons enabled for each subscriber. We utilize tiered pricing plans where our service provider partners may receive prospective pricing discounts driven by volume.

We also generate SaaS and license revenue from the fees paid to us when we license our intellectual property to third parties for use of our patents. In addition, in certain markets, our EnergyHub subsidiary sells its demand response service for an annual service fee, with pricing based on the number of subscribers or amount of aggregate electricity demand made available for a utility’s or market’s control.

Software License Revenue. Our SaaS and license revenue also includes our software license revenue from monthly fees charged to service providers on a per subscriber basis for access to our Software platform. The non-hosted software for interactive security, automation and related solutions is typically deployed and operated by the service provider in its own network operations center. Our agreements for the Software platform solution typically include software and services, such as post-contract customer support, or PCS. Software license revenue included in SaaS and license revenue is expected to continue to decline over time as we transition subscribers to our cloud-based hosted platform.

Hardware and Other Revenue. We generate hardware and other revenue primarily from the sale of video cameras, video recorders and cellular radio modules that provide access to our cloud-based platforms and, to a lesser extent, the sale of other devices, including image sensors, gunshot detection sensors and peripherals. We primarily transfer hardware to our customers upon delivery to the customer, which corresponds with the time at which the customer obtains control of the hardware. We record a reserve against revenue for hardware returns based on historical returns.

Our hardware and other revenue also includes our revenue from the sale of perpetual licenses that provide our customers in the commercial market the right to use our OpenEye video surveillance software for an indefinite period of time in exchange for a one-time license fee, which is generally paid at contract inception. Our hardware and other revenue also includes our revenue from Shooter Detection Systems related to the sale of licenses that provide our customers the right to use our indoor gunshot detection solution in exchange for license fees, which are generally paid at contract inception. Hardware and other revenue may also include activation fees charged to some of our service provider partners for activation of a new subscriber account on our platforms, as well as fees paid by service provider partners for our marketing services. The decision whether to charge an activation fee is based in part on the expected number of subscribers to be added by our service provider partners and as a result, many of our largest service provider partners do not pay an activation fee.

As a result of the COVID-19 pandemic, governments, public institutions and other organizations in many countries and localities where COVID-19 has been detected have taken certain emergency measures, and may from time to time take additional emergency measures, to combat its spread, including imposing lockdowns, shelter-in-place orders, quarantines, restrictions on travel and gatherings and the extended shutdown non-essential businesses that cannot be conducted remotely. These emergency measures remain in place to varying degrees. We have seen and anticipate we may continue to see disruption to our hardware supply chain, including limited inventory availability, increased lead times, and shipping delays, due to the impact of COVID-19 on manufacturing, production and global transportation, as well as to our sales channels due to restrictions on our service providers’ ability to meet with residential and commercial property owners who use our solutions, reluctance of service providers and property owners to meet even where such restrictions have been lifted and general economic conditions. In addition, the COVID-19 pandemic has resulted in a global slowdown of economic activity and a recession in the

35

United States and the economic situation remains fluid as parts of the economy appear to be recovering while others continue to struggle. While vaccines have been approved for use in the United States and in many other countries, and vaccination efforts are underway, it remains difficult to assess or predict the ultimate duration and economic impact of the COVID-19 pandemic. As the future impact on global supply chains from COVID-19 is difficult to predict, the full extent to which COVID-19 may negatively affect our hardware revenue is uncertain; however, if the economy fails to fully recover or there are additional shutdowns of non-essential businesses due to a resurgence of COVID-19 and the emergence and severity of COVID-19 variants, our SaaS and license revenue growth rate may be lower in future periods, with a corresponding reduction in hardware revenue, if some consumers or small businesses defer or cancel previously anticipated purchases.

Cost of Revenue

Our cost of SaaS and license revenue primarily includes the amounts paid to wireless network providers and, to a lesser extent, the costs of running our network operations centers which are expensed as incurred, as well as patent and royalty costs in connection with technology licensed from third-party providers. Our cost of SaaS and license revenue also includes our cost of software license revenue, which primarily includes the payroll and payroll-related costs of the department dedicated to providing service exclusively to those service providers that host the Software platform. Our cost of hardware and other revenue primarily includes cost of raw materials, tooling and amounts paid to our third-party manufacturer for production and fulfillment of our cellular radio modules and image sensors, and procurement costs for our video cameras, video recorders and gunshot detection sensors, which we purchase from an original equipment manufacturer, and other devices. Our cost of hardware and other revenue also includes royalty costs in connection with technology licensed from third-party providers.

We record the cost of SaaS and license revenue as expenses are incurred, which corresponds to the delivery period of our services to our subscribers. We record the cost of hardware and other revenue primarily when the hardware and other services are delivered to the service provider partner, which occurs when control of the hardware and other services transfers to the service provider partner. Our cost of revenue excludes amortization and depreciation shown in operating expenses.

Since 2019, the U.S. government has implemented and imposed significant changes to U.S. trade policy with respect to China. Tariffs have subjected certain Alarm.com products manufactured overseas to additional import duties of up to 25%. The amount of the import tariff and the number of products subject to tariffs have changed numerous times based on action by the U.S. government. Approximately one-fifth to one-half of the hardware products that we sell to our service provider partners are imported from China and could be subject to increased tariffs. While the additional import duties have resulted in an increase to our cost of hardware revenue, these import duties had a modest impact on hardware revenue margins. If tariffs are increased or are expanded to apply to more of our products, such actions may increase our cost of hardware revenue and reduce our hardware revenue margins in the future. We continue to monitor the changes in tariffs.

Operating Expenses

Our operating expenses consist of sales and marketing, general and administrative, research and development and amortization and depreciation expenses. Salaries, bonuses, stock-based compensation, benefits and other personnel related costs are the most significant components of each of these expense categories, excluding amortization and depreciation. We include stock-based compensation expense in connection with the grant of stock options and other forms of equity compensation, including equity compensation with performance conditions, in the applicable operating expense category based on the respective equity award recipient’s function (sales and marketing, general and administrative or research and development). We grew from 1,317 employees as of June 30, 2020 to 1,421 employees as of June 30, 2021, and we expect to continue to hire new employees to support the projected future growth of our business.

Sales and Marketing Expense.  Sales and marketing expense consists primarily of personnel and related expenses for our sales and marketing teams, including salaries, bonuses, stock-based compensation, benefits, travel, and commissions. Our sales and marketing teams engage in sales, account management, service provider partner support, advertising, promotion of our products and services and marketing.

The number of employees in sales and marketing functions increased from 441 as of June 30, 2020 to 456 as of June 30, 2021 and slightly decreased from 457 as of March 31, 2021. We expect to continue to invest in our sales and marketing activities to expand our business both domestically and internationally. We intend to increase the size of our sales force and our service provider partner support team to provide additional support to our existing service provider partner base to drive their productivity in selling our solutions as well as to enroll new service provider partners in North America and in international markets.

General and Administrative Expense.  General and administrative expense consists primarily of personnel and related expenses for our administrative, legal, human resources, finance and accounting personnel, including salaries, bonuses, stock-based compensation, benefits and other personnel costs. Additional expenses included in this category are legal costs, including those that are incurred to defend and license our intellectual property, as well as non-personnel costs, such as travel related expenses, rent, subcontracting and professional fees, audit fees, tax services, and insurance expenses. Also included in general and administrative expenses are credit losses and acquisition-related expenses, which consist primarily of legal, accounting and professional service fees directly related to acquisitions and valuation gains or losses on acquisition-related contingent liabilities.

36

The number of employees in general and administrative functions increased from 155 as of June 30, 2020 to 173 as of June 30, 2021 and increased from 160 as of March 31, 2021. Excluding intellectual property litigation and acquisition-related expense, we expect general and administrative costs to increase prospectively as our business grows. This includes cost increases related to accounting, finance, and legal personnel, additional external legal, audit fees and other expenses associated with regulations governing public companies. While somewhat unpredictable, we also expect to continue to incur costs related to litigation involving intellectual property. See the section of this Quarterly Report titled "Legal Proceedings" for additional information regarding litigation matters.

Research and Development Expense.  Research and development expense consists primarily of personnel and related expenses for our employees working on our product development and software and device engineering teams, including salaries, bonuses, stock-based compensation, benefits and other personnel costs. Also included are non-personnel costs such as consulting and professional fees paid to third-party development resources as well as acquisition costs of IPR&D with no alternative future use.

The number of employees in research and development functions increased from 721 as of June 30, 2020 to 792 as of June 30, 2021 and slightly decreased from 797 as of March 31, 2021. Our research and development efforts are focused on innovating new features and enhancing the functionality of our platforms and the solutions we offer to our service provider partners and subscribers. We will also continue to invest in efforts to extend our platforms to adjacent markets and internationally to maintain our leadership position in the development of intelligently connected property technology, and continued enhancement of our Enterprise Tools platform for our service provider partners.

Amortization and Depreciation.  Amortization and depreciation consists of amortization of intangible assets originating from our acquisitions as well as our internally-developed capitalized software. Our depreciation expense is related to investments in property and equipment. Acquired intangible assets include developed technology, customer related intangibles, trademarks and trade names. We expect in the near term that amortization and depreciation may fluctuate based on our acquisition activity, development of our platforms and capitalized expenditures.

Interest Expense

Interest expense consists of interest expense associated with our 2026 Notes and our 2017 Facility, which was terminated in January 2021. Interest expense is expected to increase in 2021, as compared to 2020 due to the non-cash interest expense related to the 2026 Notes issued on January 20, 2021.

Interest Income

Interest income consists of interest income earned on our cash and cash equivalents and our notes receivable.

Other Income / (Expense), Net

Other income / (expense), net primarily consists of non-operating and miscellaneous expense and income, including the $0.2 million loss on the early extinguishment of the 2017 Facility during the three months ended March 31, 2021.

Benefit from Income Taxes

We are subject to U.S. federal, state and local income taxes as well as foreign income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. As a result, we recognize tax liabilities based on estimates of whether additional taxes will be due. Our effective tax rates were below the statutory rate primarily due to research and development tax credits claimed, tax windfall benefits from employee stock-based payment transactions and foreign derived intangible income deductions, partially offset by the impact of state taxes and valuation allowances recorded against state research and development tax credit carryforwards. We recognize excess tax windfall benefits on a discrete basis during the quarter in which they occur, and we anticipate that our effective tax rate will vary from quarter to quarter depending on our stock price and exercises of stock options under our equity incentive plans each period.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue, costs and expenses during the reported period. In accordance with GAAP, we base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Because of the use of estimates inherent in the financial reporting process in light of the continuing uncertainty arising from the COVID-19 pandemic, actual results could differ from those estimates and any such differences may be material. To the extent that there are

43

differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. Except as disclosed in Note 2 of our notes to the condensed consolidated financial statement and as disclosed below, there were no other material changes to our use of estimates or other critical accounting policies from those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the SEC on February 25, 2021, or Annual Report.

Convertible Senior Notes

In accounting for the issuance of our convertible senior notes, we separate the notes into liability and equity components. The carrying amount of the liability component is calculated by measuring the fair value of a similar liability that does not have an associated convertible feature, using a discounted cash flow model with a risk adjusted yield. The carrying amount of the equity component representing the conversion option is determined by deducting the fair value of the liability component from the par value of the notes as a whole. This difference represents a debt discount that is amortized to interest expense using the effective interest method over the term of the notes. Transaction costs attributable to the liability component are netted with the liability component and amortized to interest expense using the effective interest method over the term of the notes. Transaction costs attributable to the equity component are netted with the equity component of the notes in additional paid-in capital in the condensed consolidated balance sheets.

We did not make any material changes to the underlying assumptions used to separate the notes into liability and equity components for the three and six months ended June 30, 2021 and we do not expect any material changes in the near term to the underlying assumptions used to calculate the liability and equity components of our convertible senior notes for the three and six months ended June 30, 2021. However, if changes in these assumptions occur, and, should those changes be significant, they could have a material impact on the liability and equity balances related to the convertible senior notes as well as interest expense.

Liquidity and Capital Resources

Working Capital

The following table summarizes our cash and cash equivalents, accounts receivable, net and working capital, for the periods indicated (in thousands):

	June 30, 2021		December 31, 2020
Cash and cash equivalents	$	662,682	$	253,459
Accounts receivable, net	92,612		83,326
Working capital	733,689		307,170

We define working capital as current assets minus current liabilities. Our cash and cash equivalents as of June 30, 2021 are available for working capital purposes. We do not enter into investments for trading purposes, and our investment policy is to invest any excess cash in short term, highly liquid investments that limit the risk of principal loss; therefore, our cash and cash equivalents are held in demand deposit accounts that generate very low returns.

Liquidity and Capital Resources

As of June 30, 2021, we had $662.7 million in cash and cash equivalents. We consider all highly liquid instruments purchased with an original maturity from the date of purchase of three months or less to be cash equivalents. To date, we have principally financed our operations through cash generated by operating activities and, to a lesser extent, through private and public equity and convertible senior note financings.

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026 in a private placement to qualified institutional buyers and received proceeds of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs. We used some of the proceeds to repay the $110.0 million outstanding principal balance under our 2017 Facility and also used some of the proceeds to pay accrued interest, fees and expenses related to the 2017 Facility. We terminated the 2017 Facility effective January 20, 2021. We are using the remaining net proceeds from the issuance of the 2026 Notes for working capital and other general corporate purposes, which may include acquisitions or strategic investments in complementary businesses or technologies.

In February 2021, we paid $5.0 million in cash to purchase 1,000,000 shares of Series B-2 Preferred Stock from one of our technology partners as part of a financing round that included other investors.

44

We believe our existing cash and cash equivalents and our future cash flows from operating activities will be sufficient to meet our anticipated operating cash needs for at least the next 12 months. Over the final six months of fiscal year 2021, we expect our capital expenditure requirements to be approximately $4.1 million, primarily related to the continued build out of our leased office space as well as purchases of computer software and equipment. Maturities of lease liabilities for our various office and equipment leases are as follows: $6.0 million for the remainder of 2021, $10.7 million in 2022, $10.0 million in 2023, $8.6 million in 2024, $7.5 million in 2025 and $4.8 million in 2026 and thereafter.

Our future working capital, capital expenditure and cash requirements will depend on many factors, including the impact of the COVID-19 pandemic on the economy and our operations, the rate of our revenue growth, the amount and timing of our investments in human resources and capital equipment, future acquisitions and investments, and the timing and extent of our introduction of new solutions and platform and solution enhancements. As the impact of the COVID-19 pandemic on the economy and our operations evolves, we will continue to assess our liquidity needs. To the extent our cash and cash equivalents and cash flows from operating activities are insufficient to fund our future activities, we may need to borrow additional funds or raise funds from public or private equity or debt financings. If we raise additional funds through the incurrence of indebtedness, such indebtedness would likely have rights that are senior to holders of our equity securities and could contain covenants that restrict our operations. Any additional equity financing would be dilutive to our current stockholders.

Sources of Liquidity

The 2017 Facility was a revolving credit facility with Silicon Valley Bank, or SVB, as administrative agent, and a syndicate of lenders to finance working capital and certain permitted acquisitions and investments. The 2017 Facility was available to us to refinance existing debt and for general corporate and working capital purposes including acquisitions, and prior to its termination on January 20, 2021, had a borrowing capacity of $125.0 million. We had the option to increase the borrowing capacity of the 2017 Facility to $175.0 million with the consent of the lenders. On January 20, 2021, we repaid the entire outstanding balance of $110.0 million of the 2017 Facility with proceeds from the 2026 Notes. The 2017 Facility is discussed in more detail below under “Debt Obligations.”

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026 in a private placement to qualified institutional buyers and received proceeds of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs. The convertible senior notes are discussed in more detail below under “Debt Obligations.”

Dividends

We did not declare or pay dividends during the three and six months ended June 30, 2021 and 2020. We cannot provide any assurance that we will declare or pay cash dividends on our common stock in the future. We currently anticipate that we will retain all of our future earnings, if any, for use in the operation and expansion of our business and we do not anticipate paying cash dividends in the foreseeable future. Payment of future cash dividends, if any, will be at the discretion of the board of directors after taking into account various factors, including our financial condition, operating results, current and anticipated cash needs, the requirements of current or then-existing debt instruments and other factors the board of directors deems relevant.

Stock Repurchase Programs

On November 29, 2018, our board of directors authorized a stock repurchase program, under which we were authorized to purchase up to an aggregate of $75.0 million of our outstanding common stock during the two-year period ended November 29, 2020. On December 3, 2020, our board of directors authorized another stock repurchase program, under which we are authorized to purchase up to an aggregate of $100.0 million of our outstanding common stock during the three-year period ending December 3, 2023. During the three months ended March 31, 2020, we repurchased 147,153 shares of our common stock under the program that expired on November 29, 2020 in open market purchases for a total consideration of $5.1 million. No shares were repurchased under this program during the three months ended June 30, 2020. During the three and six months ended June 30, 2021, we did not repurchase any shares of our common stock under the program that expires on December 3, 2023.

Historical Cash Flows

The following table sets forth our cash flows for the periods indicated (in thousands):

	Six Months Ended June 30,
	2021		2020
Cash flows from operating activities	$	45,308	$	48,048
Cash flows used in investing activities	(12,376)		(9,306)
Cash flows from financing activities	376,291		47,456

45

Operating Activities

Cash flows from operating activities have typically been generated from our net income and by changes in our operating assets and liabilities, particularly from accounts receivable and inventory, adjusted for non-cash expense items such as amortization and depreciation, deferred income taxes and stock-based compensation.

For the six months ended June 30, 2021, cash flows from operating activities were $45.3 million, compared to $48.0 million for the same period in the prior year. This $2.7 million decrease in cash flows from operating activities was due to a $15.0 million decrease in cash from operating assets and liabilities, partially offset by a $8.5 million increase in non-cash and other reconciling items and a $3.8 million increase in net income.

The $15.0 million decrease in cash from operating assets and liabilities was primarily due to differences in timing of collection of receipts and payments of disbursements and, to a lesser extent, increases in prepayments for long lead-time parts related to inventory and other assets during the six months ended June 30, 2021, as compared to the same period in the prior year. The $8.5 million increase in non-cash and other reconciling items was primarily due to a $7.3 million increase in amortization of the debt discount and debt issuance costs related to the convertible senior notes during the six months ended June 30, 2021 as well as a $4.5 million increase in stock-based compensation resulting from additional grants of stock options and restricted stock units during the six months ended June 30, 2021. These increases in non-cash and other reconciling items were partially offset by a $4.6 million change in deferred income taxes, primarily due to increased tax windfall benefits from employee stock-based payment transactions during the six months ended June 30, 2021, as compared to the same period in the prior year.

Investing Activities

Our investing activities typically include acquisitions, capital expenditures, investments in unconsolidated entities, notes receivable issued to companies with offerings complementary to ours and proceeds from the repayment of those notes receivable. Our capital expenditures have primarily been for general business use, including leasehold improvements as we have expanded our office space to accommodate our growth in headcount, computer equipment used internally and expansion of our network operations centers.

For the six months ended June 30, 2021, our cash flows used in investing activities was $12.4 million, as compared to $9.3 million for the same period in the prior year. The $3.1 million increase in cash flows used in investing activities was primarily due to the $5.0 million used to purchase 1,000,000 shares of Series B-2 Preferred Stock from one of our technology partners during the six months ended June 30, 2021 as well as a $2.0 million reduction in repayments of notes receivable during the six months ended June 30, 2021, as compared to the same period in the prior year. These increases in cash flows used in investing activities were partially offset by $3.3 million used to acquire in-process research and development during the six months ended June 30, 2020 that did not occur during the six months ended June 30, 2021.

Financing Activities

Cash generated by financing activities includes borrowings under the 2017 Facility, proceeds from convertible senior notes and proceeds from the issuance of common stock from employee stock option exercises and from our employee stock purchase plan. Cash used in financing activities typically includes repurchases of common stock and repayments of debt.

For the six months ended June 30, 2021, cash flows from financing activities was $376.3 million, compared to $47.5 million for the same period in the prior year. The $328.8 million increase in cash flows from financing activities was primarily due to $484.3 million in proceeds from the issuance of convertible senior notes, net of issuance costs paid. This increase in cash flows from financing activities was partially offset by the repayment of $110.0 million to terminate the 2017 Facility during the six months ended June 30, 2021 that did not occur during the same period in the prior year as well as the borrowing of $50.0 million under the 2017 Facility during the six months ended June 30, 2020 that did not occur during six months ended June 30, 2021.

Contractual Obligations

As of June 30, 2021, there were no material changes in our contractual obligations and commitments from those disclosed in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report, other than the $500.0 million issuance of the 2026 Notes in January 2021 and the $110.0 million repayment to terminate the 2017 Facility on January 20, 2021.

Debt Obligations

Convertible Senior Notes

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026 in a private placement to qualified institutional buyers, or the 2026 Notes. The terms of the 2026 Notes are governed by an Indenture, or the Indenture, by and between Alarm.com Holdings, Inc. and U.S. Bank National Association, as trustee. The 2026 Notes are senior unsecured obligations that do not bear regular interest and the principal amount of the 2026 Notes will not accrete. The 2026 Notes may bear special interest under specified circumstances related to our failure to comply with our reporting obligations under the Indenture. Special interest, if any, will be payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2021. We received proceeds from the issuance of the 2026 Notes of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs.

We may not redeem the 2026 Notes prior to January 20, 2024. We may redeem for cash, all or any portion of the 2026 Notes, at our option, on or after January 20, 2024, at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date, if the last reported sale price of our common stock has been at least 130% of the conversion price for the 2026 Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. No sinking fund is provided for the 2026 Notes.

The 2026 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding August 15, 2025, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the 2026 Notes on each applicable trading day; (2) during the five business day period immediately after any ten consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of 2026 Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the 2026 Notes on each such trading day; (3) if we call any or all of the 2026 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the 2026 Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events as set forth in the Indenture.

On or after August 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date of the 2026 Notes, holders of the 2026 Notes may convert all or any portion of their 2026 Notes at any time, regardless of the foregoing conditions. Upon conversion, we may satisfy our conversion obligation by paying or delivering, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. It is our current intent to settle the principal amount of the 2026 Notes with cash. The initial conversion rate for the 2026 Notes is 6.7939 shares of our common stock per $1,000 principal amount of 2026 Notes, which is equivalent to an initial conversion price of $147.19 per share of our common stock, subject to adjustment under certain circumstances in accordance with the terms of the Indenture. In addition, following certain corporate events that occur prior to the maturity date of the 2026 Notes or if we deliver a notice of redemption in respect of the 2026 Notes, we will, under certain circumstances, increase the conversion rate of the 2026 Notes for a holder who elects to convert its 2026 Notes (or any portion thereof) in connection with such a corporate event or convert its 2026 Notes called (or deemed called) for redemption during the related redemption period (as defined in the Indenture), as the case may be.

If we undergo a fundamental change (as defined in the Indenture), subject to certain exceptions and except as described in the Indenture, holders may require us to repurchase for cash all or any portion of their 2026 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.

The Indenture includes customary covenants and sets forth certain events of default after which the 2026 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving us after which the 2026 Notes become automatically due and payable.

We used some of the proceeds to repay the $110.0 million outstanding principal balance under our credit facility and also used some of the proceeds to pay accrued interest, fees and expenses related to our credit facility (see the section titled "2017 Facility" below). We are using the remaining net proceeds from the issuance of the 2026 Notes for working capital and other general corporate purposes, which may include acquisitions or strategic investments in complementary businesses or technologies.

47

2017 Facility

On October 6, 2017, we entered into a $125.0 million senior secured revolving credit facility, or the 2017 Facility, with SVB, as administrative agent, PNC Bank, National Association, as documentation agent, and a syndicate of lenders. Upon entry into the 2017 Facility, we borrowed $72.0 million, which was used to repay the previously outstanding balance under our previous credit facility. The 2017 Facility was set to mature in October 2022 and included an option to further increase the borrowing capacity to $175.0 million with the consent of the lenders. Costs incurred in connection with the 2017 Facility were capitalized and were being amortized as interest expense over the term of the 2017 Facility. The 2017 Facility was secured by substantially all of our assets, including our intellectual property. On March 25, 2020, we borrowed $50.0 million under the 2017 Facility as a precautionary measure in order to provide financial flexibility in light of current uncertainty in the financial markets resulting from the COVID-19 pandemic. On January 20, 2021, we repaid the entire outstanding principal balance of $110.0 million of the 2017 Facility with proceeds from the 2026 Notes and the 2017 Facility was terminated. We recognized an extinguishment loss of $0.2 million in other income / (expense), net in our condensed consolidated statements of operations during the six months ended June 30, 2021 for previously capitalized debt issuance costs related to the 2017 Facility that were unamortized at the time of the termination of the 2017 Facility.

The outstanding principal balance on the 2017 Facility accrued interest at a rate equal to, at our option, either (1) LIBOR, plus an applicable margin based on our consolidated leverage ratio, or (2) the highest of (a) the Wall Street Journal prime rate, (b) the Federal Funds rate plus 0.50%, or (c) LIBOR plus 1.00% plus an applicable margin based on our consolidated leverage ratio. During 2021 until the termination of the 2017 Facility on January 20, 2021, we elected for the outstanding principal balance to accrue interest at LIBOR plus 1.50%, LIBOR plus 1.75%, LIBOR plus 2.00%, and LIBOR plus 2.50% when our consolidated leverage ratio is less than 1.00:1.00, greater than or equal to 1.00:1.00 but less than 2.00:1.00, greater than or equal to 2.00:1.00 but less than 3.00:1.00 and greater than or equal to 3.00:1.00, respectively. The 2017 Facility also carried an unused line commitment fee of 0.20%. For the six months ended June 30, 2020, the effective interest rate on the 2017 Facility was 3.42%.

The carrying value of the 2017 Facility was zero and $110.0 million as of June 30, 2021 and December 31, 2020, respectively. The 2017 Facility included a variable interest rate that approximated market rates and, as such, we classified the liability as Level 2 within the fair value hierarchy and determined that the carrying amount of the 2017 Facility approximated its fair value as of December 31, 2020.

Non-GAAP Measures

We define Adjusted EBITDA as our net income before interest expense, interest income, other income / (expense), net, benefit from income taxes, amortization and depreciation expense, stock-based compensation expense, secondary offering expense, acquisition-related (benefit) / expense and legal costs and settlement fees incurred in connection with non-ordinary course litigation and other disputes, particularly costs involved in ongoing intellectual property litigation. We do not consider these items to be indicative of our core operating performance. The non-cash items include amortization and depreciation expense, amortization of debt discount and debt issuance costs for the 2026 Notes included in interest expense, stock-based compensation expense related to stock options and other forms of equity compensation, including, but not limited to, the sale of common stock. We do not adjust for ordinary course legal expenses resulting from maintaining and enforcing our intellectual property portfolio and license agreements. Adjusted EBITDA is not a measure calculated in accordance with GAAP. See the table below for a reconciliation of Adjusted EBITDA to net income, the most directly comparable financial measure calculated and presented in accordance with GAAP.

We have included Adjusted EBITDA in this report because it is a key measure that our management uses to understand and evaluate our core operating performance and trends, to generate future operating plans, to make strategic decisions regarding the allocation of capital and to make investments in initiatives that are focused on cultivating new markets for our solutions. We also use Adjusted EBITDA, a non-GAAP financial measure, as a performance measure under our executive bonus plan. Further, we believe the exclusion of certain expenses in calculating Adjusted EBITDA facilitates comparisons of our operating performance on a period-to-period basis and, in the case of exclusion of acquisition-related expense and certain historical legal expenses, excludes items that we do not consider to be indicative of our core operating performance. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are: (a) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; (b) Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; (c) Adjusted EBITDA does not reflect the potentially dilutive impact of equity-based compensation; (d) Adjusted EBITDA does not reflect tax payments that may represent a reduction in cash available to us; and (e) other companies, including companies in our industry, may calculate Adjusted EBITDA or similarly titled measures differently, which reduces its usefulness as a comparative measure.

48

Because of these and other limitations, you should consider Adjusted EBITDA alongside our other GAAP-based financial performance measures, net income and our other GAAP financial results. The following table presents a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP measure, for each of the periods indicated (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Adjusted EBITDA:
Net income	$	14,490	$	16,625	$	29,040	$	25,196
Adjustments:

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of foreign exchange rates.

The uncertainty that exists with respect to the economic impact of the COVID-19 pandemic continues to create significant volatility in the financial markets subsequent to the quarter ended June 30, 2021.

Market Risk

On January 20, 2021, we issued the 2026 Notes. We carry these instruments at face value less unamortized discount and unamortized issuance costs on our condensed consolidated balance sheets. However, the fair value of the 2026 Notes fluctuate when the market price of our common stock fluctuates.

Foreign Currency Exchange Risk

Because substantially all of our revenue and operating expenses are denominated in U.S. dollars, we do not believe that our exposure to foreign currency exchange risk is material to our business, financial condition or results of operations. If a significant portion of our revenue and operating expenses becomes denominated in currencies other than U.S. dollars, we may not be able to effectively manage this risk, and our business, financial condition and results of operations could be adversely affected by translation and by transactional foreign currency conversions.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the company’s management, including its chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2021. Based on the evaluation of our disclosure controls and procedures as of June 30, 2021, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

49

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our fiscal quarter ended June 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. On December 14, 2020, we acquired 100% of the issued and outstanding ownership interest units of Shooter Detection Systems, LLC, or SDS. We are currently integrating SDS into our internal control over financial reporting and do not expect this integration to materially affect our internal control over financial reporting.

As a result of the COVID-19 pandemic, we have taken precautionary measures intended to help protect our employees, service providers and subscribers, as well as the communities in which we participate, including enabling substantially all of our employees to work remotely. These temporary measures have not materially impacted our internal control over financial reporting during our fiscal quarter ended June 30, 2021.

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, believes that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On June 2, 2015, Vivint, Inc., or Vivint, filed a lawsuit against us in U.S. District Court, District of Utah, alleging that our technology directly and indirectly infringes six patents that Vivint purchased. Vivint is seeking permanent injunctions, enhanced damages and attorneys' fees. We answered the complaint on July 23, 2015. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. On August 19, 2016, the U.S. District Court, District of Utah stayed the litigation pending inter partes review by the U.S. Patent Trial and Appeal Board, or PTAB, of five of the patents in suit. In March 2017, the PTAB issued final written decisions relating to two patents finding all challenged claims unpatentable. In May 2017, the PTAB issued final written decisions relating to the remaining three patents that found certain claims unpatentable, while certain other claims were not found to be unpatentable. Vivint appealed the decisions to the U.S. Court of Appeals for the Federal Circuit, or the Federal Circuit, and we cross-appealed. In July 2018, the Federal Circuit issued orders affirming the PTAB’s March 2017 decisions that invalidated all challenged claims of two patents. The U.S. District Court, District of Utah lifted the stay on the litigation on June 26, 2017, with Vivint proceeding with its case on four of the six patents in its complaint. No trial date has been set. In September 2017, the U.S. Patent and Trademark Office, or PTO, ordered ex parte reexaminations of certain claims of two of the remaining patents in suit, at our request. On October 30, 2018 and November 5, 2018, the PTO issued final office actions in the pending reexaminations rejecting all claims being examined as unpatentable over the prior art. Nine claims asserted in the litigation were found unpatentable in the PTO rejections. Vivint appealed these rejections to the PTAB on March 29, 2019 and April 4, 2019. The PTAB issued decisions affirming the rejections on February 28, 2020 and May 4, 2020. Vivint appealed these decisions to the Federal Circuit on July 1, 2020 and April 26, 2021. On December 20, 2018, the Federal Circuit issued an order regarding the inter partes review of three of the remaining patents in suit that vacated, reversed and remanded the PTAB’s ruling with regard to the construction of a term (“communication device identification code”) as requested by Alarm.com and affirmed the PTAB’s May 2017 rulings invalidating certain of the Vivint patents in all other respects. On July 24, 2019, the PTAB issued further decisions with respect to two of the remaining patents in suit, finding additional claims unpatentable in view of the Federal Circuit’s December 20, 2018 decision. One of the claims asserted in the litigation was found unpatentable in the July 14, 2019 decisions. Vivint appealed the July 24, 2019 decisions to the Federal Circuit on September 25, 2019. On April 13, 2021, the Federal Circuit affirmed the PTAB decisions. On February 12, 2021, we filed an action in U.S. District Court, Eastern District of Virginia challenging the refusal by the PTO to proceed with additional reexaminations of the remaining patent claims asserted in the lawsuit. The U.S. District Court, Eastern District of Virginia granted the PTO’s motion to dismiss the case for lack of jurisdiction on June 22, 2021. We appealed the dismissal to the Federal Circuit on June 24, 2021.

Should Vivint prevail in proving Alarm.com infringes one or more of its patent claims, we could be required to pay damages of Vivint’s lost profits and/or a reasonable royalty for sales of our solution. Since all remaining patent claims in the litigation have

50

expired, Vivint shall not be entitled to injunctive relief as a remedy in this matter. While we believe we have valid defenses to Vivint’s claims, any of these outcomes could result in a material adverse effect on our business. Even if we were to prevail, this litigation could continue to be costly and time-consuming, divert the attention of our management and key personnel from our business operations and dissuade potential customers from purchasing our solution, which would also materially harm our business. During the course of the litigation, we anticipate announcements of the results of hearings and motions, and other interim developments related to the litigation. If securities analysts or investors regard these announcements as negative, the market price of our common stock may decline.

On October 22, 2019, EcoFactor, Inc., or EcoFactor, filed a complaint with the U.S. International Trade Commission, or ITC, naming Alarm.com Incorporated and Alarm.com Holdings, Inc., among others, as proposed respondents. The complaint alleges that Alarm.com’s smart thermostats infringe three U.S. patents owned by EcoFactor. EcoFactor is seeking a permanent limited exclusion order and permanent cease and desist order. On November 22, 2019, the ITC instituted an investigation into EcoFactor’s allegations naming Alarm.com Incorporated, Alarm.com Holdings, Inc. and others as respondents. We answered the complaint on December 19, 2019. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. An evidentiary hearing was held in November 2020. On April 20, 2021, the administrative law judge presiding over the investigation issued a final initial determination finding in favor of Alarm.com. On July 20, 2021, the ITC commissioners issued a decision affirming the ruling in favor of Alarm.com and terminated the investigation.

On November 11, 2019, EcoFactor filed a lawsuit against us in U.S. District Court, District of Massachusetts, alleging infringement of the same three patents asserted against us in the ITC. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. On December 26, 2019, the court issued an order staying the lawsuit pending the conclusion of the related ITC investigation.

On May 26, 2020, EcoFactor filed a second lawsuit against us in U.S. District Court, District of Massachusetts, alleging Alarm.com’s products and services infringe four additional U.S. patents owned by EcoFactor. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. On March 9, 2021, the PTO ordered ex parte reexamination of one of the patents asserted in the lawsuit, at Alarm.com’s request. On May 10, 2021, the PTAB instituted inter partes review of the same patent and subsequently stayed the ex parte reexamination pending the conclusion of its review. On May 13, 2021, the court issued an order staying the lawsuit until September 3, 2021 in light of the related ITC investigation.

Should EcoFactor prevail in its district court lawsuits we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to EcoFactor’s claims, the outcome of these legal claims cannot be predicted with certainty and any of these outcomes could result in an adverse effect on our business.

On July 22, 2021, Causam Enterprises, Inc., or Causam, filed a lawsuit against us in U.S. District Court, Western District of Texas, alleging that Alarm.com’s smart thermostats infringe four U.S. patents owned by Causam. Causam is seeking preliminary and permanent injunctions, enhanced damages and attorneys’ fees. Our response is due on September 13, 2021.

On July 28, 2021, Causam filed a complaint with the ITC naming Alarm.com Incorporated, Alarm.com Holdings, Inc., and EnergyHub, Inc., among others, as proposed respondents. The complaint alleges infringement of the same four patents Causam asserted in district court. Causam is seeking a permanent limited exclusion order and permanent cease and desist order. The ITC has not yet instituted an investigation into the allegations.

Should Causam prevail in an ITC investigation, Alarm.com thermostats manufactured abroad could be excluded from importation into the United States. Should Causam prevail in its district court lawsuit we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to Causam’s claims, the outcome of these legal claims cannot be predicted with certainty, and any of these outcomes could result in an adverse effect on our business.

In addition to the matters described above, we may be required to provide indemnification to certain of our service provider partners for certain claims regarding our solutions. For example, we are incurring costs associated with the indemnification of our service provider ADT, LLC in ongoing patent infringement suits.

On July 13, 2016, Applied Capital, Inc., or Applied Capital, filed a lawsuit against ADT, LLC, the ADT Corporation, and Icontrol Networks, Inc. in U.S. District Court, the District of New Mexico.  Applied Capital, Inc v. The ADT Corporation et al., D. New Mexico Case No. 1-16-cv-00815. Icontrol was dismissed without prejudice on May 22, 2017.  Applied Capital alleges that ADT’s sales of ADT Pulse directly and indirectly infringes U.S. Patent Nos. 8,378,817 and 9,728,082, which were allegedly purchased by Applied Capital. Applied Capital is seeking damages and attorneys’ fees.  ADT answered Applied Capital’s amended complaint on July 16, 2018. Among other things, ADT has asserted defenses based on non-infringement and invalidity of the patents-in-suit. On April 5, 2019, Applied Capital filed a lawsuit for breach of contract against Rodney Fox, the inventor of

51

the patents-in-suit, in the Second Judicial District Court, County of Bernalillo in New Mexico State Court (No. D-202-CV-2019-02841). Mr. Fox counterclaimed, alleging that he is the rightful owner of the patents-in-suit. Based on the dispute of ownership, on October 15, 2019, ADT filed a motion to stay in this matter pending its resolution. Applied Capital and Mr. Fox reached settlement and stipulated to dismissal of the New Mexico State Court action on October 31, 2019. Applied Capital filed its Second Amended Complaint on January 27, 2020 and ADT answered, adding a claim of inequitable conduct, on February 10, 2020. The court issued its claim construction order on August 12, 2019, fact discovery closed on November 12, 2019, expert discovery closed on March 9, 2020, and summary judgment and Daubert motions briefing closed on June 3, 2020. The parties reached settlement and the court dismissed the case on May 27, 2021.

On February 25, 2021, Vivint filed a lawsuit against ADT LLC a/k/a ADT LLC of Delaware d/b/a ADT Security Services in U.S. District Court, District of Utah, alleging that ADT Pulse, Control, and Blue each infringe one or more of six patents owned by Vivint. Vivint is seeking damages and attorneys’ fees. Vivint filed an amended complaint on March 24, 2021. ADT answered the amended complaint on April 30, 2021 and asserted defenses based on non-infringement and invalidity of all the patents in question, and inequitable conduct as to one of the patents. On June 25, 2021, ADT filed a motion for judgment on the pleadings seeking judgment in its favor as to five of the six asserted patents on the grounds that the claimed inventions are directed to ineligible subject matter.

Should Vivint prevail on the claims that one or more elements of ADT’s products infringe, we could be required to indemnify ADT for damages in the form of a reasonable royalty or ADT could be enjoined from making, using and selling our solution if a license or other right to continue selling our technology is not made available or we are unable to design around such patents, and required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. The outcome of these legal claims cannot be predicted with certainty.

We may also be a party to litigation and subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. For a description of our legal proceedings, see Note 12 to our condensed consolidated financial statements for additional information.

ITEM 1A. RISK FACTORS

Our business is subject to numerous risks. You should consider carefully the risks and uncertainties described below, in addition to other information contained in this Quarterly Report on Form 10-Q, or Quarterly Report, as well as our other public filings with the Securities and Exchange Commission, or SEC. Any of the following risks could have a material adverse effect on our business, financial condition, results of operations and prospects and cause the trading price of our common stock to decline.

Summary of Risks Affecting Our Business

The following summary highlights some of the risks you should consider with respect to our business and prospects. This summary is not complete and the risks included in the summary below are not the only risks we face. You should review and consider carefully the risks and uncertainties described later in this “Risk Factors” section, which includes a more complete discussion of the risks summarized below as well as a discussion of other risks related to our business and an investment in our common stock, as well as our other public filings with the SEC.

Any of the following risks could have a material adverse effect on our business, financial condition, results of operations and prospects and cause the trading price of our common stock to decline:

•Our quarterly results of operations have fluctuated and are likely to continue to fluctuate and may be negatively affected by the COVID-19 pandemic, the precautions we have taken in response to the pandemic, the disruption to global supply chains and any negative general economic conditions.

•Our actual operating results may differ significantly from any guidance provided. If our actual results of operations fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially.

•We may not sustain our growth rate and we may not be able to manage any future growth effectively.

•We sell security and life safety solutions and if these solutions fail for any reason, we could be subject to liability and our business, reputation and results of operations could suffer.

•Failure to maintain the security of our information and technology networks, including information relating to our service provider partners, subscribers and employees, could expose us to liability and adversely affect us.

•The markets in which we participate are highly competitive and many companies, including large technology companies, broadband and security service providers and other managed service providers, are actively targeting the home automation, security monitoring, video monitoring and energy management markets.

•We rely on our service provider network to acquire additional subscribers, and the inability of our service providers to attract additional subscribers or retain their current subscribers could adversely affect our operating results.

•We receive a substantial portion of our revenue from a limited number of service provider partners, and the loss of, or a significant reduction in, orders from one or more of our major service provider partners would result in decreased revenue and profitability.

52

•We have relatively limited visibility regarding the consumers that ultimately purchase our solutions, and we often rely on information from third-party service providers to help us manage our business. We operate in an evolving connected home market. If the connected property market does not grow as we expect or if a significant number of our target consumers choose to adopt point products that control discrete functions rather than our connected property solutions, we may not be able to achieve sustained growth or our business may decline.

•We benefit from integration of our solutions with third-party platform providers. If developers of third-party platform providers choose not to partner with us, or are acquired by our competitors, our integrated solutions platform, business and results of operations may be harmed.

•Our strategy includes pursuing acquisitions, and our potential inability to successfully consummate acquisitions or integrate newly-acquired technologies, assets or businesses may harm our financial results.

•If we are unable to adapt to technological change, including maintaining compatibility with a wide range of devices, as well as changes in access to wireless networks through which we provide our wireless alarm, notification and intelligent automation services, our ability to remain competitive could be impaired and we may need to incur significant capital expenditures to update our technology.

•We operate in a regulated industry and our business, operations and service provider partners are subject to various foreign, U.S. federal, state and local laws and regulations, including relating to consumer protection, licensing, Internet and data privacy, tax, tariff, import/export restrictions or other trade barriers. Failure to comply with applicable laws and regulations could harm our business and we may incur significant expenditures related to compliance efforts.

•We are involved from time to time in legal proceedings where a negative outcome could result in a material adverse effect on our business, financial condition, cash flows and results of operations.

•An assertion by a third party that we are infringing its intellectual property could subject us to costly and time-consuming litigation or expensive licenses that could harm our business and results of operations.

Risks Related to Our Business and Industry

Our business and results of operations may be negatively affected by the COVID-19 pandemic.

The COVID-19 pandemic has negatively impacted the global economy and global supply chains, and created significant disruption of global financial markets. Governments, public institutions and other organizations in many countries and localities where COVID-19 has been detected have taken certain emergency measures and may from time to time take additional emergency measures, to combat its spread, resurgences and variants, including imposing lockdowns, shelter-in-place orders, quarantines, restrictions on travel and gatherings and the extended shutdown of non-essential businesses that cannot be conducted remotely. These emergency measures remain in place to varying degrees. While vaccines have been approved for use in the United States and in many other countries, and vaccination efforts are underway, it remains difficult to assess or predict the ultimate duration and economic impact of the COVID-19 pandemic. To date, the COVID-19 pandemic has, and it may continue to, disrupt our hardware supply chain, including limited inventory availability, increased lead times, and shipping delays, as well as cause disruptions to and restrictions on our service providers’ ability to travel and to meet with residential and commercial property owners who use our solutions, cancellations or postponement of certain events, or temporary closures of our facilities or the facilities of our service providers or suppliers. Further, given global supply chain shortages, our service providers may be unable to source other hardware required for installation, such as security control panels and related peripherals, which could result in reduced demand for our products and services. See “We depend on our suppliers, and the loss of any key supplier could materially and adversely affect our business, financial condition, cash flows and results of operations” below. The COVID-19 pandemic has also resulted in significant volatility in global financial markets, which may reduce our ability to access capital and which could negatively affect our liquidity in the future. This economic and financial uncertainty may also negatively impact pricing for our platform or cause customers to reduce or postpone purchasing our solutions, which may, in turn, negatively affect our revenue, cash flows, results of operations and financial condition. The increased uncertainty and volatility in global markets may also negatively impact our growth opportunities whether organically or through acquisitions. Because our service provider partners have indicated that they typically have three to five-year service contracts with residential and commercial property owners who use our solutions, any such adverse effects may not be fully reflected in our results of operation until future periods.

The uncertainty caused by and the unprecedented nature of the current COVID-19 pandemic makes the long-term impact of the pandemic difficult to predict and the full extent to which it may negatively affect our industry, our supply of hardware products, our business operations or our operating results is uncertain. Weak global economic conditions, additional business disruptions or closures and spikes or surges in COVID-19 infection, also may exacerbate the impact of the pandemic. Further, we do not yet know the full effects of the COVID-19 pandemic on our suppliers and service providers. However, if the economy fails to fully recover or there are additional shutdowns of non-essential businesses due to a resurgence of COVID-19 and the emergence and severity of COVID-19 variants, our SaaS and license revenue growth rate may be lower in future periods, with a corresponding reduction in hardware revenue, if some consumers or small businesses defer or cancel previously anticipated purchases.

The ultimate impact to our results will depend to a large extent on currently unknowable developments, including the length of time the disruption and uncertainty caused by COVID-19 will continue, which will, in turn, depend on, among other things, the actions taken by authorities and other entities to effect a widespread roll-out of the available vaccines or otherwise contain COVID-19 or treat its impact, including the impact of any re-opening plans, additional closures and spikes or surges in COVID-19 infection, the emergence and severity of COVID-19 variants and individuals’ and companies’ risk tolerance regarding health

53

matters going forward, all of which are beyond our control. Accordingly, these potential impacts, while uncertain, could harm our business and adversely affect our operating results. In addition, to the extent the ongoing COVID-19 pandemic adversely affects our business and results of operations, it may also have the effect of heightening many of the other risks and uncertainties described in this “Risk Factors” section which may materially and adversely affect our business and results of operations.

Our actual operating results may differ significantly from any guidance provided.

Our guidance, including forward-looking statements, is prepared by management and is qualified by, and subject to, a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Many of these uncertainties and contingencies are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. We generally state possible outcomes as high and low ranges which are intended to provide a sensitivity analysis as variables are changed but are not intended to represent that actual results could not fall outside of the suggested ranges.

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will not materialize or will vary significantly from actual results. In particular, guidance relating to the anticipated results of operations of an acquired business is inherently more speculative in nature than other guidance as management will, necessarily, be less familiar with the business, procedures and operations of the acquired business. Similarly, guidance offered in periods of extreme uncertainty, such as the uncertainty caused by the COVID-19 pandemic and the evolving responses to the resulting public health crisis, is inherently more speculative in nature than guidance offered in periods of relative stability. Accordingly, any guidance with respect to our projected financial performance is necessarily only an estimate of what management believes is realizable as of the date the guidance is given. Actual results will vary from the guidance and the variations may be material. Investors should also recognize that the reliability of any forecasted financial data will diminish the farther in the future that the data is forecasted.

Actual operating results may be different from our guidance, and such differences may be adverse and material. In light of the foregoing, investors are urged to put the guidance in context and not to place undue reliance on it. In addition, the market price of our common stock may reflect various market assumptions as to the accuracy of our guidance. If our actual results of operations fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially.

We have taken certain precautions due to the COVID-19 pandemic that could harm our business.

In light of the uncertain and rapidly evolving situation relating to the spread of COVID-19 and shelter-in-place orders in many of the locations we have offices or other facilities, we have taken temporary precautionary measures intended to help minimize the risk of COVID-19 to our employees, service providers and subscribers, as well as the communities in which we participate. These precautionary measures could negatively impact our business. In particular, we have enabled substantially all of our employees to work remotely in compliance with relevant government advice, have suspended all non-essential travel for our employees, are canceling or postponing company-sponsored events, employee attendance at industry events and in-person work-related meetings. Although we continue to monitor the situation and may adjust our current policies as more information and guidance become available, temporarily suspending travel and shifting non-essential function employees to work-from-home could negatively impact our marketing efforts, slow down our recruiting efforts, or create operational or other challenges, including decreased productivity, any of which could harm our business. Though we are taking these precautionary measures as well as preparing our systems for the likelihood of increased cybersecurity threats, there is no guarantee that our precautions will fully protect our employees or enable us to maintain our productivity and any illnesses linked or alleged to be linked to our employees or service providers, whether accurate or not, could further harm our business. The full extent to which COVID-19 and our precautionary measures related thereto may impact our business will depend on future developments, which are highly uncertain and cannot be predicted at this time.

Our quarterly results of operations have fluctuated and are likely to continue to fluctuate. As a result, we may fail to meet or exceed the expectations of investors or securities analysts, which could cause our stock price to decline.

Our quarterly operating results, including the levels of our revenue, gross margin, cash flow and deferred revenue, may fluctuate as a result of a variety of factors, including adverse macroeconomic conditions, the product mix that we sell, the relative sales related to our platforms and solutions and other factors which are outside of our control. If our quarterly revenue or results of operations fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Fluctuations in our results of operations may be due to a number of factors, including:

•the portion of our revenue attributable to software as a service, or SaaS, and license versus hardware and other sales;

•our ability to manage the businesses we have acquired, and to integrate and manage any future acquisitions of businesses;

•fluctuations in demand, including due to seasonality or broader economic factors, for our platforms and solutions;

54

•changes in pricing by us in response to competitive pricing actions;

•our ability to increase, retain and incentivize the service provider partners that market, sell, install and support our platforms and solutions;

•the ability of our hardware vendors to continue to manufacture high-quality products and to supply sufficient components and products to meet our demands;

•the timing and success of introductions of new solutions, products or upgrades by us or our competitors and the entrance of new competitors;

•changes in our business and pricing policies or those of our competitors;

•the ability to accurately forecast revenue as we generally rely upon our service provider partner network to generate new revenue;

•our ability to control costs, including our operating expenses and the costs of the hardware we purchase;

•changes in U.S. trade policies, including new or potential tariffs or penalties on imported products;

•competition, including entry into the industry by new competitors and new offerings by existing competitors;

•issues related to introductions of new or improved products such as supply chain disruptions or shortages of prior generation products or short-term decreased demand for next generation products;

•perceived or actual problems with the security, privacy, integrity, reliability, quality or compatibility of our solutions, including those related to security breaches in our systems, our subscribers’ systems, unscheduled downtime, or outages;

•the amount and timing of expenditures, including those related to expanding our operations, including through acquisitions, increasing research and development, introducing new solutions or paying litigation expenses;

•the ability to effectively manage growth within existing and new markets domestically and abroad;

•changes in the payment terms for our platforms and solutions;

•collectability of receivables due from service provider partners and other third parties;

•the strength of regional, national and global economies; and

•the impact of natural disasters such as earthquakes, hurricanes, fires, power outages, floods, epidemics, pandemics, including COVID-19, and other catastrophic events or man-made problems such as terrorism or global or regional economic, political and social conditions.

Fluctuations in our quarterly operating results may be particularly pronounced in the current economic environment due to the uncertainty caused by and the unprecedented nature of the current COVID-19 pandemic. Due to the foregoing factors and the other risks discussed in this Quarterly Report, you should not rely on quarter-to-quarter comparisons of our results of operations as an indication of our future performance. You should not consider our recent revenue and Adjusted EBITDA growth or results of one quarter as indicative of our future performance. See the Non-GAAP Measures section of Item 2. "Management’s Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Measures," for a discussion of the limitations of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, the most comparable GAAP measurement, for the three and six months ended June 30, 2021 and 2020.

Downturns in general economic and market conditions and reductions in spending may reduce demand for our platforms and solutions, which could harm our revenue, results of operations and cash flows.

Our revenue, results of operations and cash flows depend on the overall demand for our platforms and solutions. Negative conditions in the general economy both in the United States and abroad, including conditions resulting from the COVID-19 pandemic, changes in gross domestic product growth, financial and credit market fluctuations, energy costs, international trade relations and other geopolitical issues, the availability and cost of credit and the global housing and mortgage markets could cause a decrease in consumer discretionary spending and business investment and diminish growth expectations in the U.S. economy and abroad.

During weak economic times, the available pool of service providers may decline as the prospects for home building and home renovation projects diminish, which may have a corresponding impact on our growth prospects. In addition, there is an

55

increased risk during these periods that an increased percentage of our service provider partners will file for bankruptcy protection, which may harm our reputation, revenue, profitability and results of operations. In addition, we may determine that the cost of pursuing any claim may outweigh the recovery potential of such claim. Likewise, consumer bankruptcies can detrimentally affect the business stability of our service provider partners.

The current COVID-19 pandemic has caused significant uncertainty and volatility in global markets, which has and may continue to cause consumer discretionary spending to decline for an unknown period of time. A prolonged economic slowdown and a material reduction in new home construction and renovation projects may result in diminished sales of our platforms and solutions. Further worsening, broadening or protracted extension of the economic downturn could have a negative impact on our business, revenue, results of operations and cash flows.

We sell security and life safety solutions and if our solutions fail for any reason, we could be subject to liability and our business could suffer.

We sell security and life safety solutions, which are designed to secure the safety of our subscribers and their residences or commercial properties. If these solutions fail for any reason, including due to defects in our software, a carrier outage, a failure of our network operations centers, a failure on the part of one of our service provider partners or user error, some of which have happened from time to time, we could be subject to liability for such failures and our business could suffer.

Our platforms and solutions may contain undetected defects in the software, infrastructure, third-party components or processes. In addition, due to the COVID-19 pandemic, we have enabled substantially all of our employees to work remotely which may make us more vulnerable to cyber-attacks and may create operational or other challenges, any of which could harm our systems or our business. Although we have taken precautionary measures to prepare for these threats and challenges, there is no guarantee that our precautions will fully protect our systems. We continue to monitor the situation and may adjust our current policies as more information and guidance become available. If our platforms or solutions suffer from defects, we could experience harm to our branded reputation, claims by our subscribers or service provider partners or lost revenue during the period required to address the cause of the defects. We have found and may find defects in new, acquired or upgraded solutions, resulting in loss of, or delay in, market acceptance of our platforms and solutions, which could harm our business, financial condition, cash flows or results of operations.

Since solutions that enable our platforms are installed by our service provider partners, if they do not install or maintain such solutions correctly, our platforms and solutions may not function properly. If the improper installation or maintenance of our platforms and solutions leads to service or equipment failures after introduction of, or an upgrade to, our platforms or a solution, we could experience harm to our branded reputation, claims by our subscribers or service provider partners or lost revenue during the period required to address the cause of the problem. Further, we rely on our service provider partners to provide the primary source of support and ongoing service to our subscribers and, if our service provider partners fail to provide an adequate level of support and services to our subscribers, it could have a material adverse effect on our reputation, business, financial condition, cash flows or results of operations.

Any defect in, or disruption to, our platforms and solutions could cause consumers not to purchase additional solutions from us, prevent potential consumers from purchasing our platforms and solutions or harm our reputation. Although our contracts with our service provider partners limit our liability to our service provider partners for these defects, disruptions or errors, we nonetheless could be subject to litigation for actual or alleged losses to our service provider partners or our subscribers, which may require us to spend significant time and money in litigation or arbitration, or to pay significant settlements or damages. Defending a lawsuit, regardless of its merit, could be costly, divert management's attention and affect our ability to obtain or maintain liability insurance on acceptable terms and could harm our business. Although we currently maintain some warranty reserves, we cannot assure you that these warranty reserves will be sufficient to cover future liabilities.

Our business is subject to the risks of earthquakes, hurricanes, fires, power outages, floods, pandemics, natural disasters and other catastrophic events, and to interruption by man-made problems such as terrorism or global or regional economic, political and social conditions.

A significant natural disaster, such as an earthquake, hurricane, fire, flood, or a public health pandemic, such as COVID-19, or a significant power outage could harm our business, financial condition, cash flows and results of operations. The impact of climate change may increase these risks due to changes in weather patterns, such as increases in storm intensity, sea-level rise, melting of permafrost and temperature extremes in areas where we conduct our business. Natural disasters could affect our hardware vendors, our wireless carriers or our network operations centers. Further, if a natural disaster occurs in a region from which we derive a significant portion of our revenue, such as metropolitan areas in North America, consumers in that region may delay or forego purchases of our platforms and solutions from service providers in the region, which may harm our results of operations for a particular period. In addition, terrorist acts or acts of war could cause disruptions in our business or the business of our hardware vendors, service providers, subscribers or the economy as a whole. More generally, these and other geopolitical, social and economic conditions could result in increased volatility in worldwide financial markets and economies that could harm our sales. Given our concentration of sales during the second and third quarters, any disruption in the business of our hardware vendors, service provider partners or subscribers that impacts sales during the second or third quarter of each year could have a greater impact on our annual results. All of the aforementioned risks may be augmented if the disaster recovery plans for us, our

56

service provider partners and our suppliers prove to be inadequate. To the extent that any of the above results in delays or cancellations of orders, or delays in the manufacture, deployment or shipment of our platforms and solutions, our business, financial condition, cash flows and results of operations would be harmed.

We may not sustain our growth rate and we may not be able to manage any future growth effectively.

We have experienced significant growth and also have substantially expanded our operations in a short period of time. Our revenue increased from $338.9 million in 2017 to $618.0 million in 2020 and increased from $293.6 million for the six months ended June 30, 2020 to $361.4 million for the six months ended June 30, 2021. We do not expect to achieve similar growth rates in future periods. You should not rely on our operating results for any prior quarterly or annual periods as an indication of our future operating performance. If we are unable to maintain expected revenue growth in both absolute dollars and as a percentage of prior period revenue, our financial results could suffer and our stock price could decline.

Our future operating results depend, to a large extent, on our ability to successfully manage any future expansion and growth. To successfully manage our growth and obligations as a public company, we believe we must effectively, among other things:

•maintain our relationships with existing service provider partners and add new service provider partners;

•increase our subscriber base and help our service provider partners maintain and improve their revenue retention rates, while also expanding their cross-sell effectiveness;

•manage our relationships with our hardware vendors and other key suppliers;

•add, train and integrate sales and marketing personnel;

•expand our international operations; and

•continue to implement and improve our administrative, financial and operational systems, procedures and controls.

We intend to continue to invest in research and development, sales and marketing, and general and administrative functions and other areas to grow our business. We are likely to recognize the costs associated with these increased investments earlier than some of the anticipated benefits and the return on these investments may be lower, or may develop more slowly, than we expect, which could adversely affect our operating results.

If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities or develop new solutions or enhancements to our existing solutions and we may fail to satisfy subscriber and service provider partner requirements, maintain the quality of our solutions, execute on our business plan or respond to competitive pressures, which could result in our financial results suffering and a decline in our stock price.

We have expanded our business rapidly in recent periods. If we fail to manage the expansion of our operations and infrastructure effectively, we may be unable to execute our business plan, maintain high levels of service or address competitive challenges adequately.

We increased our number of full-time employees from 784 as of December 31, 2017 to 1,421 as of June 30, 2021. Our growth has placed, and may continue to place, a significant strain on our managerial, administrative, operational, financial and other resources. We intend to further expand our overall business, service provider partner network, subscriber base, headcount and operations, including by acquiring other businesses. Creating and maintaining a global organization and managing a geographically dispersed workforce requires substantial management effort and significant additional investment in our infrastructure. We will be required to continue to improve our operational, financial and management controls and our reporting procedures to ensure timely and accurate reporting of our operational and financial results and we may not be able to do so effectively. As such, we may be unable to manage our expenses effectively in the future, which may negatively impact our gross profit or operating expenses in any particular quarter. If we fail to manage our anticipated growth and change in a manner that preserves the key aspects of our corporate culture, the quality of our solutions may suffer, which could negatively affect our brand and reputation and harm our ability to retain and attract service provider partners and consumers.

From time to time, we are involved in legal proceedings where a negative outcome, including an adverse litigation judgment or settlement, could expose us to monetary damages or limit our ability to operate our business, resulting in a material adverse effect on our business, financial condition, cash flows and results of operations.

We are involved and have been involved in the past in legal proceedings from time to time, including claims directly against us or claims against certain of our service provider partners where we have agreed to indemnify those service provider partners. For example, on June 2, 2015, Vivint filed a lawsuit against us alleging that our technology directly and indirectly infringes six patents purchased by Vivint. On November 11, 2019, EcoFactor, Inc., or EcoFactor, filed a lawsuit against us in U.S. District Court, District of Massachusetts, alleging that Alarm.com’s smart thermostats infringe three U.S. patents owned by EcoFactor.

57

On May 26, 2020, EcoFactor filed a second lawsuit against us in U.S. District Court, District of Massachusetts, alleging Alarm.com’s products and services infringe four additional U.S. patents owned by EcoFactor. On July 22, 2021, Causam Enterprises, Inc., or Causam, filed a lawsuit against us in U.S. District Court, Western District of Texas, alleging that Alarm.com’s smart thermostats infringe four U.S. patents owned by Causam. On July 28, 2021, Causam filed a complaint with the U.S. International Trade Commission, or ITC, naming Alarm.com Incorporated, Alarm.com Holdings, Inc., and EnergyHub, Inc., among others, as proposed respondents. The complaint alleges infringement of the same four patents Causam asserted in district court. See the section of this Quarterly Report titled "Legal Proceedings" for additional information regarding each of these matters and the other legal proceedings we are involved in. We may not be able to accurately assess the risks related to any of these suits, and we may be unable to accurately assess our level of exposure as the results of any litigation, investigations and other legal proceedings are inherently unpredictable and expensive. Any claims against us, whether meritorious or not, could be time consuming, result in costly litigation, damage our reputation, require significant amounts of management time and divert significant resource. Companies in our industry have been subject to claims related to patent infringement, regulatory matters, and product liability, as well as contract and employment-related claims. As a result of patent infringement and other intellectual property proceedings, we have, and may be required to seek in the future, licenses under patents or intellectual property rights owned by third parties, including open-source software and other commercially available software, which can be costly, or cross-license agreements relating to our and third-party intellectual property. The outcome of legal claims and proceedings against us cannot be predicted with certainty, and a negative outcome could result in a material adverse effect on our business, financial condition, cash flows and results of operations.

Our business operates in a regulated industry.

Our business, operations and service provider partners are subject to various U.S. federal, state and local consumer protection laws, licensing regulation and other laws and regulations, and to similar laws and regulations in the other countries in which we operate. Our advertising and sales practices and that of our U.S. service provider partner network are subject to regulation by the U.S. Federal Trade Commission, or the FTC, in addition to state consumer protection laws. The FTC and the Federal Communications Commission have issued regulations that place restrictions on, among other things, unsolicited automated telephone calls to residential and wireless telephone subscribers by means of automatic telephone dialing systems and the use of prerecorded or artificial voice messages. If our service provider partners were to take actions in violation of these regulations, such as telemarketing to individuals on the "Do Not Call" registry or using automatic telephone dialing systems and prerecorded or artificial voice messages, we could be subject to fines, penalties, private actions or enforcement actions by government regulators. Although we have taken steps to insulate ourselves from any such wrongful conduct by our service provider partners, and to contractually require our service provider partners to comply with these laws and regulations, we have in the past incurred costs to settle alleged violations of the Telephone Consumer Protection Act, or TCPA, and no assurance can be given that we will not be exposed to future liability as result of our service provider partners’ conduct. Further, to the extent that any changes in law or regulation further restrict the lead generation activity of our service provider partners, these restrictions could result in a material reduction in subscriber acquisition opportunities, reducing the growth prospects of our business and adversely affecting our financial condition and future cash flows. In addition, most states in which we operate have licensing laws directed specifically toward the monitored security services industry. Our business relies heavily upon cellular telephone service to communicate signals. Cellular telephone companies are currently regulated by both federal and state governments. State-level privacy and data security laws in California and various other U.S. states regulate our, and our service provider partners’, use, collection, and disclosure of subscribers’ personal information. A number of proposed privacy bills in other U.S. states could place restrictions on how we and our service provider partners use personal information and market to consumers in those states. Other laws and regulations, including consumer protection laws, laws and regulations governing advertising and sales practices, as well as privacy and data security laws and regulations apply in the other countries in which we operate. See “Evolving government and industry regulation and changes in applicable laws relating to the Internet and data privacy may increase our expenditures related to compliance efforts or otherwise limit the solutions we can offer, which may harm our business and adversely affect our financial condition” below. Changes in laws or regulations could require us to change the way we operate, which could increase costs or otherwise disrupt operations. In addition, failure to comply with any such applicable laws or regulations could result in substantial fines or revocation of our operating permits and licenses, including in geographic areas where our services have substantial penetration, which could adversely affect our business, financial condition, cash flows and results of operations. Further, if these laws and regulations were to change or if we fail to comply with such laws and regulations as they exist today or in the future, our business, financial condition, cash flows and results of operations could be materially and adversely affected.

The markets in which we participate are highly competitive and many companies, including large technology companies, broadband and security service providers and other managed service providers, are actively targeting the home automation, security monitoring, video monitoring and energy management markets. If we are unable to compete effectively with these companies, our sales and profitability could be adversely affected.

We compete in several markets, including security, video, automation, energy management and wellness solutions. The markets in which we participate are highly competitive and competition may intensify in the future.

Our ability to compete depends on a number of factors, including:

•our platforms and solutions’ functionality, performance, ease of use and installation, reliability, availability and cost effectiveness relative to that of our competitors’ products;

58

•our success in utilizing new and proprietary technologies to offer solutions and features previously not available in the marketplace;

•our success in identifying new markets, applications and technologies;

•our ability to attract and retain service provider partners;

•our name recognition and reputation;

•our ability to recruit software engineers and sales and marketing personnel; and

•our ability to protect our intellectual property.

Consumers may prefer to purchase from their existing suppliers rather than a new supplier regardless of product performance or features. In the event a consumer decides to evaluate a new home automation, security monitoring, video monitoring, energy management, or wellness solution, the consumer may be more inclined to select one of our competitors whose product offerings are broader than those that we offer. In addition, while the COVID-19 pandemic continues, consumers may prefer to purchase products that they can install themselves. If there are continuing restrictions on our service providers’ ability to meet with residential and commercial property owners in person, our ability to compete will depend on our ability to make our products available for remote installation or to make certain of our products easily installable by consumers rather than solely by our service providers.

Our current competitors include providers of other technology platforms for the connected property with interactive security, including Alula (formed following the merger of ipDatatel, LLC and Resolution Products, LLC), Avigilon Corporation, Brivo Inc., Digital Monitoring Products Inc., Eagle Eye Networks Inc., Honeywell International Inc., Resideo Technologies Inc., SecureNet Technologies, LLC, Telular Corporation (acquired by AMETEK, Inc.), United Technologies Corporation, and Verkada Inc., which sell solutions to service providers, cable operators, technology retailers and other residential and commercial automation providers. We also compete with interactive, monitored security solutions sold directly to subscribers and may also be sold through our partners, including companies like Abode Systems, Inc., Arlo Technologies, Inc., Cove Smart, LLC, Scout Security, Inc. and SimpliSafe, Inc. In addition, our service provider partners compete with security solutions sold directly to subscribers, as well as managed service providers, such as cable television, telephone and broadband companies like AT&T Inc., Comcast Cable Communications, LLC and Rogers Communications, Inc., and providers of point products, including Google Inc.'s Nest Labs, Inc. Amazon.com offers Amazon Home Services security packages with bundled equipment and professional installation, and Amazon Key, a security camera and smart lock integration feature. Ring Inc., owned by Amazon.com, offers a connected video doorbell, video cameras and an integrated security system, Ring Alarm. Samsung's SmartThings offers a security system and a home automation and awareness hub. Arlo Technologies, Inc. and Wyze Labs, Inc. offers connected video cameras, a connected video doorbell, and smart security devices. Apple Inc. offers a feature that allows some manufacturers’ connected devices and accessories, including video cameras and doorbells, to be controlled through its HomeKit service available in Apple’s iOS operating system. Additionally, Canary and other companies offer all in one video monitoring and awareness devices. In addition, we may compete with other large and small technology companies that offer control capabilities among their products, applications and services, and have ongoing development efforts to address the broader connected home market.

Many of our competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater financial, technical, sales, marketing, distribution and other resources than we have. We expect to encounter new competitors as we enter new markets as well as increased competition, both domestically and internationally, from other established and emerging home automation, security monitoring, video monitoring and automation, wellness, and energy management companies as well as large technology companies. In addition, there may be new technologies that are introduced that reduce demand for our solutions or make them obsolete. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties and rapidly acquire significant market share. Increased competition could also result in price reductions and loss of market share, any of which could result in lower revenue and negatively affect our ability to grow our business.

Aggressive business tactics by our competitors may reduce our revenue.

Increased competition in the markets in which we compete may result in aggressive business tactics by our competitors, including:

•selling at a discount;

•offering products similar to our platforms and solutions on a bundled basis at no charge;

•announcing competing products combined with extensive marketing efforts;

•providing financing incentives to consumers; and

59

•asserting intellectual property rights irrespective of the validity of the claims.

Our service provider partners may switch and offer the products and services of competing companies, which would adversely affect our sales and profitability. Competition from other companies may also adversely affect our negotiations with service provider partners and suppliers, including, in some cases, requiring us to lower our prices. Opportunities to take market share using innovative products, services and sales approaches may also attract new entrants to the field. We may not be able to compete successfully with the offerings and sales tactics of other companies, which could result in the loss of service provider partners offering our platforms and solutions and, as a result, our revenue and profitability could be adversely affected.

If we fail to compete successfully against our current and future competitors, or if our current or future competitors employ aggressive business tactics, including those described above, demand for our platforms and solutions could decline, we could experience cancellations of our services to consumers, or we could be required to reduce our prices or increase our expenses.

The proper and efficient functioning of our network operations centers and data back-up systems is central to our solutions.

Our solutions operate with a hosted architecture and we update our solutions regularly while our solutions are operating. If our solutions and/or upgrades fail to operate properly, our solutions could stop functioning for a period of time, which could put our users at risk. Our ability to keep our business operating is highly dependent on the proper and efficient operation of our network operations centers and data back-up systems. Although our network operations centers have back-up computer and power systems, if there is a catastrophic event, natural disaster, terrorist attack, security breach or other extraordinary event, we may be unable to provide our subscribers with uninterrupted monitoring service or may be unable to adequately protect confidential information and data from unauthorized access or loss. Furthermore, because data back-up systems are susceptible to malfunctions and interruptions (including those due to equipment damage, power outages, human error, computer viruses, computer hacking, data corruption and a range of other hardware, software and network problems), we cannot guarantee that we will not experience data back-up failures in the future. A significant or large-scale security breach, malfunction or interruption of our network operations centers or data back-up systems could adversely affect our ability to keep our operations running efficiently or could result in unauthorized access to or loss of data. If such an event results in unauthorized access to or loss of service provider partner, subscriber, employee or other personally identifiable data subject to data privacy and security laws and regulations, then it could result in substantial fines by U.S. federal and state authorities, foreign data privacy authorities in the European Union, or the EU, Canada, and other countries, and/or private claims by companies or individuals. If a malfunction or security breach results in a wider or sustained disruption, it could have a material adverse effect on our reputation, business, financial condition, cash flows or results of operations.

Failure to maintain the security of our information and technology networks, including information relating to our service provider partners, subscribers and employees, could adversely affect us.

We are dependent on information technology networks and systems, including the Internet, to process, transmit and store electronic information and, in the normal course of our business, we collect and retain certain information pertaining to our service provider partners, subscribers and employees, including credit card information for many of our service provider partners and certain of our subscribers. If security breaches in connection with the delivery of our solutions allow unauthorized third parties to access any of this data or obtain control of our subscribers’ systems, our reputation, business, financial condition, cash flows and results of operations could be harmed.

The legal, regulatory and contractual environment surrounding information security, privacy and credit card fraud is constantly evolving and companies that collect and retain such information are under increasing attack by cyber-criminals around the world. Further, as the regulatory focus on privacy issues continues to increase and worldwide laws and regulations concerning the protection of data and personal information expand and become more complex, these potential risks to our business will intensify. A significant actual or potential theft, loss, fraudulent use or misuse of service provider partner, subscriber, employee or other personally identifiable data, whether by third parties or as a result of employee malfeasance or otherwise, non-compliance with our contractual or other legal obligations regarding such data or a violation of our privacy and security policies with respect to such data could result in loss of confidential information, damage to our reputation, early termination of our service provider partner contracts, litigation, regulatory investigations or actions and other liabilities or actions against us, including significant fines by U.S. federal and state authorities, foreign data privacy authorities in the EU, Canada, and other countries and private claims by companies and individuals for violation of data privacy and security regulations. To the extent that any such exposure leads to credit card fraud or identity theft, we may experience a general decline in consumer confidence in our business, which may lead to an increase in attrition rates or may make it more difficult to attract new subscribers. If any one of these risks materializes our business, financial condition, cash flows or results of operations could be materially and adversely affected.

60

If our security measures are breached, including any breaches caused by cyber-attacks, our reputation may be damaged, we may be exposed to significant liabilities under U.S. and foreign laws, and our business and results of operations may be adversely affected.

Cyber-attacks from computer hackers and cyber criminals and other malicious Internet-based activity continue to increase generally, and perpetrators of cyber-attacks may be able to develop and deploy viruses, worms, ransomware, malware, DNS attacks, wireless network attacks, attacks on our cloud networks, phishing attempts, social engineering attempts, distributed denial of service attacks and other advanced persistent threats or malicious software programs that attack our products and services, our networks and network endpoints or otherwise exploit any security vulnerabilities of our products, services and networks. Techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until launched against a target. As a result, we may be unable to anticipate these techniques or to implement adequate preventative measures. We cannot be certain that advances in cyber-capabilities or other developments will not compromise or breach the technology protecting the networks that access our platforms and solutions, and we can make no assurance that we will be able to detect, prevent, timely and adequately address or mitigate the negative effects of cyber-attacks or other security breaches. In addition, due to the COVID-19 pandemic, we have enabled substantially all of our employees to work remotely which may make us more vulnerable to cyber-attacks or other security breaches.

Security breaches of, or sustained attacks against, our networks and infrastructure could create system disruptions and shutdowns that could result in disruptions to our operations or unauthorized access to or loss of our data. If such an event results in unauthorized access to or loss of any data subject to data privacy and security laws and regulations, then we could be subject to substantial fines by U.S. federal and state authorities, foreign data privacy authorities in the EU, Canada, and other countries, and private claims by companies or individuals. A system disruption, shutdown, or loss of data may result in adverse publicity and therefore adversely affect the market's perception of the security and reliability of our services. A cyber-attack may cause additional costs, such as investigative and remediation costs, and the costs of providing individuals and/or data owners with notice of the breach, legal fees and the costs of any additional fraud detection activities required by law, a court or a third-party. Additionally, some of our customer contracts require us to indemnify customers from damages they may incur as a result of a breach of our networks and systems. There can be no assurance that the limitation of liability provisions in our contracts for a security breach would be enforceable or would otherwise protect us from any such liabilities or damages with respect to any particular claim. While we maintain general liability insurance coverage and coverage for technology errors or omissions, we cannot assure you that such coverage will be available in sufficient amounts to cover one or more large claims related to a breach, will continue to be available on acceptable terms or at all. If any one of these risks materializes, our business, financial condition, cash flows or results of operations could be materially and adversely affected.

We rely on our service provider partner network to acquire additional subscribers, and the inability of our service provider partners to attract additional subscribers or retain their current subscribers could adversely affect our operating results.

Substantially all of our revenue is generated through the sales of our platforms and solutions by our service provider partners, who incorporate our solutions in certain of the products and packages they sell to their customers, and our service provider partners are responsible for subscriber acquisition, as well as providing customer service and technical support for our platforms and solutions to the subscribers. We provide our service provider partners with specific training and programs to assist them in selling and providing support for our platforms and solutions, but we cannot assure you that these steps will be effective. In addition, we rely on our service provider partners to sell our platforms and solutions into new markets in the intelligent and connected property space. If our service provider partners are unsuccessful in marketing, selling and supporting our platforms and solutions, our operating results could be adversely affected.

In order for us to maintain our current revenue sources and grow our revenues, we must effectively manage and grow relationships with our service provider partners. Recruiting and retaining qualified service provider partners and training them in our technology and solutions requires significant time and resources and has been made more challenging by the shelter-in-place orders and travel restrictions which were, and may from time to time be, implemented in many locations to combat the COVID-19 pandemic, which orders and restrictions to varying degrees remain in place. If we fail to maintain our relationships with existing service provider partners or develop relationships with new service provider partners, our revenue and operating results would be adversely affected. In addition, to execute on our strategy to expand our sales internationally, we must develop, manage and grow relationships with service provider partners that sell into these markets.

Any of our service provider partners may choose to offer a product from one of our competitors instead of our platforms and solutions, elect to develop their own competing solutions or simply discontinue their operations with us. For example, we entered into a license agreement in November 2013 with Vivint Inc., or Vivint, pursuant to which we granted a license to use the intellectual property associated with our connected home solutions. Under the terms of this arrangement, Vivint has transitioned from selling our solutions directly to its customers to selling its own home automation product to its new customers. We now generate revenue from a monthly fee charged to Vivint on a per customer basis from sales of this service provider partner’s product; however, these monthly fees are less on a per customer basis than fees we receive from our SaaS solutions. Therefore, we receive less revenue on a per customer basis from Vivint compared to our SaaS subscriber base, which may result in a lower revenue growth rate. Similarly, we entered into a patent license agreement with ADT pursuant to which we granted a license to use certain Alarm.com intellectual property following the termination or expiration of the initial term of our master service

61

agreement with ADT. Under the terms of the license, beginning in 2023, ADT will pay us a monthly royalty for each subscriber to its branded residential interactive security, automation and video service offerings that is covered by any of our licensed patents and not supported on our platforms. We must also work to expand our network of service provider partners to ensure that we have sufficient geographic coverage and technical expertise to address new markets and technologies. While it is difficult to estimate the total number of available service provider partners in our markets, there are a finite number of service provider partners that are able to perform the types of technical installations required for our platforms and solutions. In the event that we saturate the available service provider pool, or if market or other forces cause the available pool of service providers to decline, it may be increasingly difficult to grow our business. If we are unable to expand our network of service provider partners, our business could be harmed.

As consumers’ product and service options grow, it is important that we enhance our service provider partner footprint by broadening the expertise of our service provider partners, working with larger and more sophisticated service provider partners and expanding the mainstream solutions our service provider partners offer. If we do not succeed in this effort, our current and potential future service provider partners may be unable or unwilling to broaden their offerings to include our connected property solutions, resulting in harm to our business.

We receive a substantial portion of our revenue from a limited number of service provider partners, and the loss of, or a significant reduction in, orders from one or more of our major service provider partners would result in decreased revenue and profitability.

Our success is highly dependent upon establishing and maintaining successful relationships with a variety of service provider partners. We market and sell our platforms and solutions through a channel assisted sales model and we derive substantially all of our revenue from these service provider partners. We generally enter into agreements with our service provider partners outlining the terms of our relationship, including service provider pricing commitments, installation, maintenance and support requirements, and our sales registration process for registering potential sales to subscribers. These service provider contracts typically have an initial term of one year, with subsequent renewal terms of one year, and are terminable at the end of the initial term or renewal terms without cause upon written notice to the other party. In some cases, these contracts provide the service provider partner with the right to terminate prior to the expiration of the term without cause upon 30 days written notice, or, in the case of certain termination events, the right to terminate the contract immediately. While we have developed a network of over 10,000 service provider partners to sell, install and support our platforms and solutions, we receive a substantial portion of our revenue from a limited number of channel partners and significant customers. During the years ended December 31, 2020, 2019 and 2018, our 10 largest revenue service provider partners accounted for 48%, 52% and 57% of our revenue, respectively. ADT LLC, or ADT, represented greater than 15% but not more than 20% of our revenue in 2018, 2019, and 2020. ADT also represented more than 10% of accounts receivable as of December 31, 2020.

We amended our master service agreement with ADT, or MSA, to extend the initial term through January 1, 2023 and to provide for the integration of certain third party products into the ADT Command and Control software platform which we operate. In connection with the amendment to the MSA, we agreed to provide ADT a license to use certain Alarm.com intellectual property following the termination or expiration of the initial term of the MSA for which ADT will pay us a monthly royalty for each subscriber to its ADT branded residential interactive security, automation and video service offerings that is covered by any of our licensed patents and not enabled by one of our software platforms. We cannot assure you that we will be able to meet the conditions set forth in the amended agreement. If our MSA with ADT expires or terminates, we would continue to generate revenue from each subscriber that is already installed on one of our platforms for the life of that subscriber account but the number of such subscribers would likely decline over time. While we would generate revenue from ADT subscribers not on our platform using service offerings covered by any of our licensed patents from the per subscriber royalty fee charged to ADT under the patent license, these monthly fees will be less on a per subscriber basis than fees we receive from our SaaS solutions. In addition, even if ADT continues to use other services that we offer, we cannot assure you that the revenue from ADT or new accounts added by ADT will reach or exceed historical levels in any future period. We may not be able to offset any unanticipated decline in revenue from ADT with revenues from new customers or other existing customers. Any negative developments in ADT’s business, or any significant decrease in revenue from or loss of ADT as a customer could materially and adversely harm our business, financial condition, cash flows and results of operations.

We anticipate that we will continue to be dependent upon a limited number of service provider partners for a significant portion of our revenue for the foreseeable future and, in some cases, a portion of our revenue attributable to individual service provider partners may increase in the future. The loss of one or more key service provider partners, a reduction in sales through any major service provider partners or the inability or unwillingness of any of our major service provider partners to pay for our platforms and solutions would reduce our revenue and could impair our profitability.

Substantially all of the revenues associated with the non-hosted software platform are from a single customer and the loss of this customer could harm our operating results.

In March 2017, we acquired certain assets related to the Connect business unit of Icontrol Networks, Inc., or Icontrol, and all of the outstanding equity interests of the two subsidiaries through which Icontrol conducted its Piper business, which we refer to in this report as the Acquisition. Historically, ADT has accounted for, and continues to account for, substantially all of the revenue of the Connect business unit. In connection with the Acquisition we amended our master service agreement with ADT to cover

62

services provided with respect to the non-hosted software platform, or Software platform. We cannot assure you that ADT will use the Software platform for its new customers or keep existing customers on the Software platform. In addition, even if ADT continues to use the Software platform, we cannot assure you that the revenue from ADT or new accounts added by ADT will reach or exceed historical levels of revenue for the Connect business unit in any future period. Any negative developments in ADT’s business, or any significant decrease in revenue from or loss of ADT as a customer could materially and adversely harm our business, financial condition, cash flows and results of operations.

We have relatively limited visibility regarding the consumers that ultimately purchase our solutions, and we often rely on information from third-party service providers to help us manage our business. If these service providers fail to provide timely or accurate information, our ability to quickly react to market changes and effectively manage our business may be harmed.

We sell our solutions through service provider partners. These service provider partners work with consumers to design, install, update and maintain their connected home and commercial installations and manage the relationship with our subscribers. While we are able to track orders from service provider partners and have access to certain information about the configurations of their Alarm.com systems that we receive through our platforms, we also rely on service provider partners to provide us with information about consumer behavior, product and system feedback, consumer demographics and buying patterns. We use this channel sell-through data, along with other metrics, to forecast our revenue, assess consumer demand for our solution, develop new solutions, adjust pricing and make other strategic business decisions. Channel sell-through data is subject to limitations due to collection methods and the third-party nature of the data and thus may not be complete or accurate. If we do not receive consumer information on a timely or accurate basis, or if we do not properly interpret this information, our ability to quickly react to market changes and effectively manage our business may be harmed.

Consumers may choose to adopt point products that provide control of discrete functions rather than adopting our connected property solutions. If we are unable to increase market awareness of the benefits of our unified solutions, our revenue may not continue to grow, or it may decline.

Many vendors have emerged, and may continue to emerge, to provide point products with advanced functionality for use in connected properties, such as a video doorbell or thermostat that can be controlled by an application on a smartphone. We expect more and more consumer electronic and consumer appliance products to be network-aware and connected — each very likely to have its own smart device (phone or tablet) application. Consumers may be attracted to the relatively low costs of these point products and the ability to expand their connected property control solution over time with minimal upfront costs, despite some of the disadvantages of this approach, which may reduce demand for our connected property solutions. If so, our service provider partners may switch and offer the point products and services of competing companies, which would adversely affect our sales and profitability. If a significant number of consumers in our target market choose to adopt point products rather than our connected property solutions, then our business, financial condition, cash flows and results of operations will be harmed, and we may not be able to achieve sustained growth or our business may decline.

Mergers or other strategic transactions involving our competitors could weaken our competitive position, which could adversely affect our ability to compete effectively and harm our results of operations.

Our industry is highly fragmented, and we believe it is likely that some of our existing competitors will consolidate or be acquired. In addition, some of our competitors may enter into new alliances with each other or may establish or strengthen cooperative relationships with systems integrators, third-party consulting firms or other parties. Any such consolidation, acquisition, alliance or cooperative relationship could adversely affect our ability to compete effectively and lead to pricing pressure and our loss of market share and could result in a competitor with greater financial, technical, marketing, service and other resources, all of which could harm our business, financial condition, cash flows and results of operations.

We are dependent on our connected property solutions, and the lack of continued market acceptance of our connected property solutions would result in lower revenue.

Our connected property solutions account for substantially all of our revenue and will continue to do so for the foreseeable future. As a result, our revenue could be reduced by:

•any decline in demand for our connected property solutions;

•the failure of our connected property solutions to achieve continued market acceptance;

•the introduction of products and technologies that serve as a replacement or substitute for, or represent an improvement over, our connected property solutions;

•technological innovations or new communications standards that our connected property solutions do not address; and

•our inability to release enhanced versions of our connected property solutions on a timely basis.

63

We are vulnerable to fluctuations in demand for Internet-connected devices in general and interactive security systems in particular. If the market for connected home and commercial solutions grows more slowly than anticipated or if demand for connected home and commercial solutions does not grow as quickly as anticipated, whether as a result of competition, product obsolescence, technological change, unfavorable economic conditions, uncertain geopolitical environments, budgetary constraints of our consumers or other factors, we may not be able to continue to increase our revenue and earnings and our stock price would decline.

A significant decline in our SaaS and license revenue renewal rate would have an adverse effect on our business, financial condition, cash flows and results of operations.

We generally bill our service provider partners based on the number of subscribers they have on our platforms and the features being utilized by subscribers on a monthly basis in advance. Subscribers could elect to terminate our services in any given month. If our efforts and our service provider partners’ efforts to satisfy our existing subscribers are not successful, we may not be able to retain them or sell additional functionality to them and, as a result, our revenue and ability to grow could be adversely affected. We track our SaaS and license revenue renewal rate on an annualized basis, as reflected in the section of this Quarterly Report titled "Management’s Discussion and Analysis of Financial Condition and Results of Operations — Other Business Metrics — SaaS and License Revenue Renewal Rate." However, our service provider partners, who resell our services to our subscribers, have indicated that they typically have three to five-year service contracts with our subscribers. Our SaaS and license revenue renewal rate is calculated across our entire subscriber base, including subscribers whose contract with their service provider reached the end of its contractual term during the measurement period, as well as subscribers whose contract with their service provider has not reached the end of its contractual term during the measurement period, and is not intended to estimate the rate at which our subscribers renew their contracts with our service provider partners. As a result, we may not be able to accurately predict future trends in renewals and the resulting churn. Subscribers may choose not to renew their contracts for many reasons, including the belief that our service is not required for their needs or is otherwise not cost-effective, a desire to reduce discretionary spending, or a belief that our competitors’ services provide better value. Additionally, our subscribers may not renew for reasons entirely out of our control, such as moving a residence or the dissolution of their business, which is particularly common for small to mid-sized businesses. A significant increase in our churn would have an adverse effect on our business, financial condition, cash flows or results of operations.

If we are unable to develop new solutions, sell our platforms and solutions into new markets or further penetrate our existing markets, our revenue may not grow as expected.

Our ability to increase sales will depend, in large part, on our ability to enhance and improve our platforms and solutions, introduce new solutions in a timely manner, sell into new markets and further penetrate our existing markets. The success of any enhancement or new solution or service depends on several factors, including the timely completion, introduction and market acceptance of enhanced or new solutions, the ability to maintain and develop relationships with service providers, the ability to attract, retain and effectively train sales and marketing personnel and the effectiveness of our marketing programs. Any new product or service we develop or acquire may not be introduced in a timely or cost-effective manner, and may not achieve the broad market acceptance necessary to generate significant revenue. Any new markets into which we attempt to sell our platforms and solutions, including new vertical markets and new countries or regions, may not be receptive. Our ability to further penetrate our existing markets depends on the quality, availability and reliability of our platforms and solutions and our ability to design our platforms and solutions to meet consumer demand.

We benefit from integration of our solutions with third-party platform providers. If these developers choose not to partner with us, or are acquired by our competitors, our business and results of operations may be harmed.

Our solutions are incorporated into the hardware of our third-party platform providers. For example, our hardware platform partners produce control devices that deliver our platform services to subscribers. It may be necessary in the future to renegotiate agreements relating to various aspects of these solutions or other third-party solutions. The inability to easily integrate with, or any defects in or disruption in the supply or availability of, any third-party solutions could result in increased costs, or in delays in new product releases or updates to our existing solutions until such issues have been resolved, which could have a material adverse effect on our business, financial condition, cash flows, results of operations and future prospects and could damage our reputation. In addition, if these third-party solution providers choose not to partner with us, choose to integrate their solutions with our competitors’ platforms, or are unable or unwilling to update their solutions, our business, financial condition, cash flows and results of operations could be harmed. Further, if third-party solution providers that we partner with or that we would benefit from partnering with are acquired by our competitors, they may choose not to offer their solutions on our platforms, which could adversely affect our business, financial condition, cash flows and results of operations.

We rely on wireless carriers to provide access to wireless networks through which we provide our wireless alarm, notification and intelligent automation services, and any interruption of such access and any significant costs related to such interruption could materially and adversely impact our business, financial condition, cash flows, results of operation and reputation.

We rely on wireless carriers to provide access to wireless networks for machine-to-machine data transmissions, which are an integral part of our services. Our wireless carriers may suspend wireless service to expand, maintain or improve their

64

networks, or may discontinue or sunset older wireless networks as new technology evolves. For example, certain cellular carriers have announced their intention to shut down their 3G and CDMA wireless networks by the end of 2022 which may require our subscribers to upgrade to alternative and potentially more expensive technologies. See “The technology we employ may become obsolete, and we may need to incur significant capital expenditures to update our technology” below. Further, wireless carriers from time to time suffer service outages which range from local to national in scale during which security control panels may be unable to transmit life safety signals to emergency responders. Any such wireless carrier service disruptions could materially and adversely impact our ability to provide services to our service provider partners and subscribers and result in significant costs, which could materially and adversely impact our business, results of operations and reputation. In addition, product changes by wireless carriers, price increases or changes to existing contract terms or termination of our agreements could also have a material and adverse impact on our business, financial condition, cash flows and results of operations.

If we are unable to adapt to technological change, including maintaining compatibility with a wide range of devices, our ability to remain competitive could be impaired.

The market for connected home and commercial solutions is characterized by rapid technological change, frequent introductions of new products and evolving industry standards. Our ability to attract new subscribers and increase revenue from existing subscribers will depend in significant part on our ability to anticipate changes in industry standards, to continue to enhance our existing solutions or introduce new solutions on a timely basis to keep pace with technological developments, and to maintain compatibility with a wide range of connected devices in residential and commercial properties. We may change aspects of our platforms and may utilize open source technology in the future, which may cause difficulties including compatibility, stability and time to market. The success of any enhanced or new product or solution will depend on several factors, including the timely completion and market acceptance of the enhanced or new product or solution. Similarly, if any of our competitors implement new technologies before we are able to implement them, those competitors may be able to provide more effective products than ours, possibly at lower prices. Any delay or failure in the introduction of new or enhanced solutions could harm our business, financial condition, cash flows and results of operations.

The technology we employ may become obsolete, and we may need to incur significant capital expenditures to update our technology.

Our industry is characterized by rapid technological innovation. Our platforms and solutions interact with the hardware and software technology of systems and devices located at our subscribers’ properties and we depend upon cellular, broadband and other telecommunications providers to provide communication paths to our subscribers in a timely and efficient manner. We may be required to implement new technologies or adapt existing technologies in response to changing market conditions, consumer preferences or industry standards, which could require significant capital expenditures. The discontinuation of cellular communication technology, cellular networks or other services by telecommunications service providers can affect our services and require our subscribers to upgrade to alternative and potentially more expensive, technologies. For example, certain cellular carriers have announced their intention to shut down their 3G and CDMA wireless networks by the end of 2022. We intend to work with our service providers to develop a transition plan over the next two years to convert or upgrade the equipment of end user accounts reliant upon 3G or CDMA networks, and we expect to incur incremental costs over the next two years related to the planned 3G and CDMA network shutdown. If our service providers are not able to convert or upgrade the equipment of their customers who are currently using 3G or CDMA network technology, then those accounts may be terminated with us when such networks are no longer available.

It is also possible that one or more of our competitors could develop a significant technical advantage that allows them to provide additional or superior quality products or services, or to lower their price for similar products or services, which could put us at a competitive disadvantage. Our inability to adapt to changing technologies, market conditions or consumer preferences in a timely manner could materially and adversely affect our business, financial condition, cash flows or results of operations.

We depend on our suppliers, and the loss of any key supplier could materially and adversely affect our business, financial condition, cash flows and results of operations.

Our hardware products depend on the availability and quality of components that we procure from third-party suppliers. Reliance on suppliers, as well as industry supply conditions, generally involves several risks, including the possibility of defective parts, which can adversely affect the reliability and reputation of our platforms and solutions, and a shortage of components and reduced control over delivery schedules and increases in component costs, which can adversely affect our profitability. These supply chain risks are heightened in the current environment where continuing travel restrictions and shelter-in-place orders as well as limitations on factory capacity, including labor shortages, and delays in shipping times due to the COVID-19 pandemic have and may continue to adversely affect production of and the timing of delivery of components. Shortages of essential components of our products or significantly increased lead times for obtaining such components may lead to delays in our production, and we may be unable to fulfill orders for our hardware products on a timely basis or at all. Even if we are able to procure components from alternative sources, we may be required to pay more for them, which could adversely affect our profitability. We are working with our suppliers to secure components and materials to account for longer lead times and limited availability, but we cannot assure you that our efforts will be successful or that demand for our hardware products will continue at the same level. In addition, global transportation disruptions have led to slower shipping times generally, while reductions in passenger air travel have also led to reduced capacity and increased costs for air freight shipments, which may continue to

65

adversely affect the timing and cost of delivery of components, materials and products. Any of these disruptions to our inventory and supply chain could have a material adverse effect on our business, financial condition, cash flows and results of operations. We have several large hardware suppliers from which we procure hardware on a purchase order basis, including one supplier that supplied products and components which generated 16% of our hardware and other revenue for the six months ended June 30, 2021. From time to time we provide advance payments or loans to our vendors to, for example, secure procurement of long lead time parts or to provide bridge financing to ensure continuity of operations. If these suppliers are unable to continue to provide a timely and reliable supply, we could experience interruptions in delivery of our platforms and solutions to our service provider partners, which could have a material adverse effect on our business, financial condition, cash flows and results of operations. If we were required to find alternative sources of supply, qualification of alternative suppliers and the establishment of reliable supplies could result in delays and a possible loss of sales, which could have a material adverse effect on our business, financial condition, cash flows and results of operations.

Growth of our business will depend on market awareness and a strong brand, and any failure to develop, maintain, protect and enhance our brand would hurt our ability to retain or attract subscribers.

We believe that building and maintaining market awareness, brand recognition and goodwill in a cost-effective manner is important to our overall success in achieving widespread acceptance of our existing and future solutions and is an important element in attracting new service provider partners and subscribers. An important part of our business strategy is to increase service provider and consumer awareness of our brand and to provide marketing leadership, services and support to our service provider partner network. This will depend largely on our ability to continue to provide high-quality solutions, and we may not be able to do so effectively. While we may choose to engage in a broader marketing campaign to further promote our brand, this effort may not be successful. Our efforts in developing our brand may be hindered by the marketing efforts of our competitors and our reliance on our service provider partners and strategic partners to promote our brand. If we are unable to cost-effectively maintain and increase awareness of our brand, our business, financial condition, cash flows and results of operations could be harmed.

We operate in the emerging and evolving connected property market, which may develop more slowly or differently than we expect. If the connected property market does not grow as we expect, or if we cannot expand our platforms and solutions to meet the demands of this market, our revenue may decline, fail to grow or fail to grow at an accelerated rate, and we may incur operating losses.

The market for solutions that bring objects and systems not typically connected to the Internet, such as home automation, security monitoring, video monitoring, energy management and wellness solutions, into an Internet-like structure is still developing, and it is uncertain how rapidly or how consistently this market will continue to develop and the degree to which our platforms and solutions will be accepted into the markets in which we operate. Some consumers may be reluctant or unwilling to use our platforms and solutions for a number of reasons, including satisfaction with traditional solutions, concerns about additional costs, concerns about data privacy and lack of awareness of the benefits of our platforms and solutions. Our ability to expand the sales of our platforms and solutions into new markets depends on several factors, including the awareness of our platforms and solutions, the timely completion, introduction and market acceptance of our platforms and solutions, the ability to attract, retain and effectively train sales and marketing personnel, the ability to develop relationships with service providers, the effectiveness of our marketing programs, the costs of our platforms and solutions and the success of our competitors. If we are unsuccessful in developing and marketing our platforms and solutions into new markets, or if consumers do not perceive or value the benefits of our platforms and solutions, the market for our platforms and solutions might not continue to develop or might develop more slowly than we expect, either of which would harm our revenue and growth prospects.

Risks of liability from our operations are significant.

The nature of the solutions we provide, including our interactive security solutions, and new technologies we may acquire, such as in our recent acquisition of Shooter Detection Systems, LLC, potentially exposes us to greater risks of liability for data privacy and security, employee acts or omissions, or technology or system failure than may be inherent in other businesses. Substantially all of our service provider partner agreements contain provisions limiting our liability to service provider partners and our subscribers in an attempt to reduce this risk. However, in the event of litigation with respect to these matters, we cannot assure you that these limitations will be enforced, and the costs of such litigation could have a material adverse effect on us. Moreover, in the event of any regulatory investigations or actions against us related to these matters, we could be subject to additional risks and liabilities, including significant fines by U.S. federal and state authorities, foreign data privacy authorities in the EU, Canada, and other countries, in addition to the costs of such investigations, all of which could have a material adverse effect on us. In addition, there can be no assurance that we are adequately insured for these risks. Certain of our insurance policies and the laws of some states may limit or prohibit insurance coverage for punitive or certain other types of damages or liability arising from gross negligence.

66

Our strategy includes pursuing acquisitions, and our potential inability to successfully integrate newly-acquired technologies, assets or businesses may harm our financial results. Future acquisitions of technologies, assets or businesses which are paid for partially or entirely through the issuance of stock or stock rights could dilute the ownership of our existing stockholders.

We believe part of our growth will continue to be driven by acquisitions of other companies or their technologies, assets and businesses. For example, on October 21, 2019, we acquired 85% of the issued and outstanding shares of capital stock of PC Open Incorporated, doing business as OpenEye, and on December 14, 2020, we acquired Shooter Detection Systems, LLC. We have acquired other businesses in the past. For example, we acquired the assets of HiValley Technology Inc. in March 2015, assets of ObjectVideo, Inc. in January 2017 and Icontrol's Connect and Piper business units in March 2017. These acquisitions and any other acquisitions we may complete in the future will give rise to certain risks, including:

•incurring higher than anticipated capital expenditures and operating expenses;

•failing to assimilate and integrate the operations and personnel or failing to retain the key personnel of the acquired company or business;

•failing to retain customers and service providers and other third-party business partners seeking to terminate or renegotiate their relationships with us;

•failing to integrate the acquired technologies, or incurring significant expense to integrate acquired technologies into our platforms and solutions;

•disrupting our ongoing business;

•encountering complexities associated with managing a larger, more complex and growing business;

•diverting our management’s attention and other company resources;

•failing to maintain uniform standards, controls and policies;

•incurring significant accounting charges;

•impairing relationships with employees, service provider partners or subscribers;

•finding that the acquired technology, asset or business does not further our business strategy, that we overpaid for the technology, asset or business or that we may be required to write off acquired assets or investments partially or entirely;

•failing to realize the expected synergies of the transaction;

•being exposed to unforeseen liabilities and contingencies that were not identified prior to acquiring the company; and

•being unable to generate sufficient revenue and profits from acquisitions to offset the associated acquisition costs.

Fully integrating an acquired technology, asset or business into our operations may take a significant amount of time. We may not be successful in overcoming these risks or any other problems encountered with acquisitions. To the extent we do not successfully avoid or overcome the risks or problems related to any such acquisitions, or fail to manage the acquired business or execute our integration and growth strategy in an efficient and effective manner, our business, financial condition, cash flows and results of operations could be harmed. Acquisitions also could impact our financial position and capital requirements, or could cause fluctuations in our quarterly and annual results of operations. Acquisitions could include significant goodwill and intangible assets, which may result in future impairment charges that would reduce our stated earnings. We may incur significant costs in our efforts to engage in strategic transactions and these expenditures may not result in successful acquisitions.

We expect that the consideration we might pay for any future acquisitions of technologies, assets or businesses could include stock, rights to purchase stock, cash or some combination of the foregoing. If we issue stock or rights to purchase stock in connection with future acquisitions, net income per share and then-existing holders of our common stock may experience dilution.

We may pursue business opportunities that diverge from our current business model, which may cause our business to suffer.

We may pursue business opportunities that diverge from our current business model, including but not limited to expanding our platforms and solutions and investing in new and unproven technologies. We can offer no assurance that any such new business opportunities will prove to be successful. Among other negative effects, our pursuit of such business opportunities could

67

reduce operating margins and require more working capital, subject us to additional federal state, and local laws and regulations, materially and adversely affect our business, financial condition, cash flows or results of operations.

Evolving government and industry regulation and changes in applicable laws relating to the Internet and data privacy may increase our expenditures related to compliance efforts or otherwise limit the solutions we can offer, which may harm our business and adversely affect our financial condition.

As Internet commerce continues to evolve, federal, state or foreign agencies have adopted and could in the future adopt regulations covering issues such as user privacy and content. We are particularly sensitive to these risks because the Internet is a critical component of our SaaS business model. In addition, taxation of products or services provided over the Internet or other charges imposed by government agencies or by private organizations for accessing the Internet may be imposed. Any regulation imposing greater fees for Internet use or restricting information exchange over the Internet could result in a decline in the use of the Internet and the viability of Internet-based services, which could harm our business.

Our platforms and solutions enable us to collect, manage and store a wide range of data related to our subscribers’ interactive security, intelligent automation, video monitoring, energy management and wellness systems. A valuable component of our platforms and solutions is our ability to analyze this data to present the user with actionable business intelligence. We obtain our data from a variety of sources, including our service provider partners, our subscribers and third-party providers. We cannot assure you that the data we require for our proprietary data sets will be available from these sources in the future or that the cost of such data will not increase. The United States federal government and various state governments have adopted or proposed limitations on the collection, distribution, storage and use of personal information. Several foreign jurisdictions, including the European Union and the United Kingdom, have adopted legislation (including directives or regulations) that is more rigorous governing data collection and storage than in the United States.

On June 28, 2018, the State of California enacted the California Consumer Privacy Act of 2018, or CCPA, which took effect on January 1, 2020. The CCPA governs the collection, sale and use of California residents’ personal information, and significantly impacts businesses’ handling of personal information and privacy policies and procedures. The CCPA, as well as data privacy laws that have been adopted or proposed in other states, may limit our ability to use, process and store certain data, which may decrease adoption of our platforms and solutions, affect our relationships with service provider partners and our suppliers, increase our costs for compliance, and harm our business, financial condition, cash flows and results of operations. Specifically, the CCPA may subject us to regulatory fines by the State of California, individual claims, class actions, and increased commercial liabilities. In addition, the California Privacy Rights Act of 2020, or CPRA, was approved by California voters and will be effective as of January 1, 2023. The CPRA will, among other things, amend the CCPA by creating additional privacy rights for California consumers and additional obligations on businesses, which could subject us to additional compliance costs as well as potential fines, individual claims, class actions and commercial liabilities.

European data protection laws, including the General Data Protection Regulation, or GDPR, generally restrict the transfer of personal data from Europe, including the European Economic Area, or EEA, UK and Switzerland, to the United States and most other countries unless the parties to the transfer have implemented specific safeguards to protect the transferred personal data. On July 16, 2020, the Court of Justice of the European Union, or CJEU, invalidated the EU-U.S. Privacy Shield framework, a program for transferring personal data from the EEA to the United States. The ruling also raised questions about whether one of the primary alternatives to the EU-U.S. Privacy Shield, namely the European Commission’s Standard Contractual Clauses, or SCCs, can lawfully be used for transfers from the EEA to the United States or most other countries. While the CJEU did not invalidate the use of SCCs as a valid mechanism for transferring personal data from the EEA to the United States, the CJEU required entities relying on SCCs to, among other things, verify on a case-by-case basis that the SCCs provide adequate protection of personal data under European Union, or EU, law by providing, where necessary, additional safeguards to those offered by the existing SCCs. For data transfers to the United States, these additional safeguards must be added to the SCCs in order for entities to use SCCs as a valid data transfer mechanism. Furthermore, the CJEU and the European Data Protection Board advised European data protection authorities that they would need to closely examine the laws and practices of countries outside of the EEA where EEA personal data is transferred, with a particular focus on the United States, so data transfers to the United States from the EEA are subject to more regulatory scrutiny following the CJEU decision.

We have historically relied on both the EU-U.S. Privacy Shield and SCCs for transferring personal data from the EEA, and as a result of the CJEU ruling, we are transitioning any data transfers covered under the EU-U.S. Privacy Shield to be covered under SCCs. In June 2021, the European Commission adopted a new version of the SCCs, which we must begin using by September 27, 2021. We have until December 27, 2022 to implement the new SCCs with all of our EEA customers and vendors who are sub-processors and receive access to personal data from our EEA customers. Moreover, the UK data protection regulator is developing new SCCs for transferring personal data from the UK. When those UK-specific SCCs are finalized, we will be required to execute those SCCs with our customers in the UK.

Our transition from relying on the EU-U.S. Privacy Shield to adopting, implementing and complying with the new SCCs may slow down our contracting process and increase our legal and compliance costs (including an increase in exposure to substantial fines under EEA data protection laws as well as injunctions against processing or transferring personal data from the EEA), which could adversely affect our cash flows and financial condition. SCCs with additional safeguards and obligations put in place by EEA data protection authorities or customers may impose new restrictions on our business and could affect our operations in the EEA.

68

In September 2020, the Swiss Federal Data Protection and Information Commissioner, or FDPIC, determined that the Swiss-U.S. Privacy Shield Framework does not provide an adequate level of data protection for data transfers from Switzerland to the U.S. While the FDPIC does not have the authority to invalidate the Swiss-U.S. Privacy Shield, the FDPIC’s announcement casts serious doubt on the viability of the Swiss-U.S. Privacy Shield as a valid mechanism for Swiss-U.S. data transfers. As a result of the FDPIC decision, we will need to transition any data transfers covered under the Swiss-U.S. Privacy Shield to be covered under SCCs, and the FDPIC will likely require us to adopt the new SCCs.

As a result of these ongoing changes, there will continue to be significant regulatory uncertainty surrounding the validity of data transfers from the EEA, UK and Switzerland to the United States. The inability to import personal data from the EEA, UK or Switzerland may require us to increase our data processing capabilities in those jurisdictions at significant expense. Various other non-EU jurisdictions may also choose to impose data localization laws limiting the transfer of personal data out of their respective jurisdictions, or our EEA, UK or Swiss service provider partners may require similar contractual restrictions regarding data localization. Such laws or contractual restrictions may increase our costs for compliance, and harm our business, financial condition, cash flows and results of operations.

The EU's General Data Protection Regulation, or GDPR, went into effect on May 25, 2018. Prior to May 25, 2018, we updated our existing privacy and data security measures to comply with GDPR. As guidance on compliance with GDPR from the EU data protection authorities evolves over time, our privacy or data security measures may be deemed or perceived to be in noncompliance with current or future laws and regulations, which may subject us to litigation, regulatory investigations or other liabilities and could limit the products and services we can offer in certain jurisdictions. Further, in the event of a breach of personal information that we hold, we may be subject to governmental fines, individual claims, remediation expenses and/or harm to our reputation. Moreover, if future laws, regulations, or court rulings, such as the CJEU’s decision invalidating the EU-U.S. Privacy Shield, limit our ability to use and share this data or our ability to store, process and share data over the Internet, demand for our platforms and solutions could decrease, our costs could increase, and our business, financial condition, cash flows and results of operations could be harmed.

Furthermore, Brazil’s comprehensive privacy law, the General Data Protection Law, or LGPD, took effect on September 18, 2020 and federal regulatory enforcement began on August 1, 2021. However, private and state-level enforcement of the law began in September 2020. The LGPD creates a new legal framework for the use, processing and storage of Brazilians’ personal data, and it adds significant privacy and security obligations for companies processing personal data in Brazil. The LGPD may limit our and our service providers’ ability to use, process and store certain data, which may decrease adoption of our platforms and solutions, affect our relationships with our service provider partners and suppliers, increase our costs for compliance, and harm our business, financial condition, cash flows and results of operations. In addition, the LGPD may subject us to regulatory fines by the Brazilian Data Protection Authority and increased commercial liabilities.

Since April 2018 we have offered a solution for certain service provider partners who may be subject to the Health Insurance Portability and Accountability Act of 1996, and its implementing regulations, or HIPAA, which regulates the use and disclosure of Protected Health Information, or PHI. As a result, we are subject to HIPAA when PHI is accessed, created, maintained or transmitted through our solution by these service provider partners. We have implemented additional privacy and security policies and procedures, as well as administrative, physical and technical safeguards to enable our solution to be HIPAA-compliant. Additionally, HIPAA compliance has required us to put in place certain agreements with contracting partners and to appoint a Privacy Officer and Security Officer. If our privacy and security policies or other safeguards for PHI are deemed to be in noncompliance by the United States Department of Health and Human Services, or HHS, we may be subject to litigation, regulatory investigations or other liabilities. In the event of a breach of PHI that we hold, we may be subject to governmental fines, individual claims under state privacy laws governing personal health information, remediation expenses and/or harm to our reputation. Furthermore, if future changes to HIPAA or state privacy laws governing PHI expand the definition of PHI or put more restrictions on our ability to use, process and store PHI, then HIPAA compliance for our solutions as currently constituted may be costly both financially and in terms of administrative resources. Ongoing compliance efforts may take substantial time and require the assistance of external resources, such as attorneys, information technology, and/or other consultants and advisors.

We rely on the performance of our senior management and highly skilled personnel, and if we are unable to attract, retain and motivate well-qualified employees, our business and results of operations could be harmed.

We believe our success has depended, and continues to depend, on the efforts and talents of senior management and key personnel, including Stephen Trundle, our Chief Executive Officer, and our senior information technology managers. Our future success depends on our continuing ability to attract, develop, motivate and retain highly qualified and skilled employees. Qualified individuals are in high demand, and we may incur significant costs to attract them. In addition, the loss of any of our senior management or key personnel, including as a result of the COVID-19 pandemic, could interrupt our ability to execute our business plan, as such individuals may be difficult to replace. If we do not succeed in attracting well-qualified employees or retaining and motivating existing employees, our business and results of operations could be harmed.

We provide minimum service level commitments to certain of our service provider partners, and our failure to meet them could cause us to issue credits for future services or pay penalties, which could harm our results of operations.

Certain of our service provider partner agreements currently, and may in the future, provide minimum service level commitments regarding items such as uptime, functionality or performance. If we are unable to meet the stated service level

69

commitments for these service provider partners or suffer extended periods of service unavailability, we are or may be contractually obligated to provide these service provider partners with credits for future services, provide services at no cost or pay other penalties, which could adversely impact our revenue. We have incurred such penalties in the past, which have reduced our revenue. We do not currently have any reserves on our balance sheet for these commitments.

We have indemnity obligations to certain of our service provider partners for certain expenses and liabilities, which could force us to incur substantial costs.

We have indemnity obligations to certain of our service provider partners for certain claims regarding our platforms and solutions, including security breach, product recall, epidemic failure, and product liability claims. As a result, in the case of any such claims against these service provider partners, we could be required to indemnify them for losses resulting from such claims or to refund amounts they have paid to us. We expect that some of our service provider partners may seek indemnification from us in the event that such claims are brought against them. In addition, we may elect to indemnify service provider partners where we have no contractual obligation to do so and we will evaluate each such request on a case-by-case basis. If a service provider partner elects to invest resources in enforcing a claim for indemnification against us, we could incur significant costs disputing it. If we do not succeed in disputing it, we could face substantial liability. See "We have indemnity obligations to certain of our service provider partners for certain expenses and liabilities resulting from intellectual property infringement claims regarding our platforms and solutions, which could force us to incur substantial costs" below for details on indemnity obligations resulting from intellectual property.

We may be subject to significant additional liabilities as a result of the Acquisition for which we will not be indemnified.

In connection with the Acquisition, we assumed certain historic liabilities of the Connect and Piper business units, including pre-closing liabilities relating to current and former employees of the Connect and Piper business units, pre-closing compliance by the Connect and Piper business units with applicable laws and pre-closing performance by the Connect and Piper business units of the assumed contracts. In addition, we assumed any liabilities that may arise from certain pending intellectual property litigation. In addition to the known liabilities we assumed, there could be unasserted claims or assessments that we failed or were unable to discover or identify in the course of performing due diligence investigations and there may be liabilities that are neither probable nor estimable at this time which may become probable and estimable in the future. Further, while the terms of the Acquisition transaction documents provide for us to be indemnified for breaches of certain representations and warranties made about the Connect and Piper business units, the liabilities that arise may not entitle us to contractual indemnification or our contractual indemnification may not be effective. Any such liabilities, individually or in the aggregate, could have a material adverse effect on our business and our prospects.

The incurrence or issuance of debt may impact our financial position and subject us to additional financial and operating restrictions.

On October 6, 2017, we entered into a $125.0 million senior secured revolving credit facility, or the 2017 Facility, with Silicon Valley Bank, or SVB, as administrative agent, PNC Bank, National Association, as documentation agent, and a syndicate of lenders. Upon entry into the 2017 Facility, we borrowed $72.0 million, which was used to repay the previously outstanding balance under our previous credit facility. On November 30, 2018, we amended the 2017 Facility to incorporate the parameters that must be met for us to repurchase our outstanding common stock under the stock repurchase program authorized by our board of directors on November 29, 2018. On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026 in a private placement to qualified institutional buyers, or the 2026 Notes. We received proceeds from the issuance of the 2026 Notes of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs. We used some of the proceeds to repay the $110.0 million outstanding principal balance under our 2017 Facility and also used some of the proceeds to pay accrued interest, fees and expenses related to the 2017 Facility. We terminated the 2017 Facility effective January 20, 2021. We intend to invest a portion of the proceeds in a portfolio of securities and other investments and although we plan to follow an established investment policy and seek to minimize the credit risk associated with investments by limiting exposure to any one issuer depending on credit quality, we cannot give assurances that the assets in our investment portfolio will not lose value, become impaired or suffer from illiquidity.

Our overall leverage and certain obligations contained in the related documentation could adversely affect our financial health and business and future operations by, among other things:

•making it more difficult to satisfy our obligations, including under the terms of the 2026 Notes;

•limiting our ability to refinance our debt on terms acceptable to us or at all;

•limiting our flexibility to plan for and adjust to changing business and market conditions and increasing our vulnerability to general adverse economic and industry conditions;

•limiting our ability to use our available cash flow to fund future acquisitions, working capital, business activities, and other general corporate requirements; and

70

•limiting our ability to obtain additional financing for working capital, to fund growth or for general corporate purposes, even when necessary to maintain adequate liquidity.

Any of the foregoing could have a material adverse effect on our business, financial condition, cash flows or results of operations.

We may not be able to secure additional financing on favorable terms, or at all, to meet our future capital needs.

In the future, we may require additional capital to respond to business opportunities, challenges, acquisitions or unforeseen circumstances and may determine to engage in equity or debt financings or enter into credit facilities for other reasons. For example, on January 20, 2021, we issued the 2026 Notes. We received proceeds from the issuance of the 2026 Notes of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs. We may require additional capital to respond to the significant uncertainty arising from the COVID-19 pandemic and we may not be able to timely secure additional debt or equity financing on favorable terms or at all. Any debt financing obtained by us in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us, when we require it, our ability to continue to grow or support our business and to respond to business challenges could be limited. See “Risks Related to our Outstanding Convertible Senior Notes” below for further details on risks related to the 2026 Notes.

Goodwill and other identifiable intangible assets represent a significant portion of our total assets, and we may never realize the full value of our intangible assets.

As of June 30, 2021, we had $207.6 million of goodwill and identifiable intangible assets. Goodwill and other identifiable intangible assets are recorded at fair value on the date of acquisition. We review such assets for impairment at least annually. Impairment may result from, among other things, deterioration in performance, adverse market conditions, including adverse market conditions arising from the COVID-19 pandemic, adverse changes in applicable laws or regulations, including changes that restrict the activities of or affect the solutions we offer, challenges to the validity of certain registered intellectual property, reduced sales of certain products or services incorporating registered intellectual property, increased attrition and a variety of other factors. The amount of any quantified impairment must be expensed immediately as a charge to results of operations. Depending on future circumstances, it is possible that we may never realize the full value of our intangible assets. Any future determination of impairment of goodwill or other identifiable intangible assets could have a material adverse effect on our financial position and results of operations.

Comprehensive tax reform bills could adversely affect our business and financial condition.

The U.S. government enacted the Tax Cuts and Jobs Act, or the Tax Act, into law on December 22, 2017. The 2017 Tax Act included significant changes to the taxation of business entities. These changes included, among others, (i) a permanent reduction to the corporate income tax rate, (ii) a partial limitation on the deductibility of business interest expense, (iii) a shift of the U.S. taxation of multinational corporations from a tax on worldwide income to a territorial system (along with certain rules designed to prevent erosion of the U.S. income tax base) and (iv) a base erosion and anti-abuse tax on base erosion payments if the federal group has sufficient gross receipts. Future changes in tax laws, including as a result of changes proposed by the new Presidential administration, or tax rulings could also materially affect our effective tax rate. In particular, the reduction in the corporate income tax rate resulting from the 2017 Tax Act could be reduced or rescinded by future tax law changes. The overall impact of any potential tax reform is uncertain, and our business and financial condition could be adversely affected.

We may be subject to additional tax liabilities, which would harm our results of operations.

We are subject to income, sales, use, value added and other taxes in the United States and other countries in which we conduct business, which laws and rates vary greatly by jurisdiction. Certain jurisdictions in which we do not collect sales, use, value added or other taxes on our sales may assert that such taxes are applicable, which could result in tax assessments, penalties and interest, and we may be required to collect such taxes in the future. Additionally, longstanding international tax norms that determine each country’s jurisdiction to tax cross-border international trade are subject to potential evolution. An outgrowth of the original Base Erosion and Profit Shifting project is a project undertaken by the more than 130 member countries of the expanded Organization for Economic Cooperation and Development Inclusive Framework focused on "Addressing the Challenges of the Digitalization of the Economy." The breadth of this project is likely to impact all multinational businesses by potentially redefining jurisdictional taxation rights. Significant judgment is required in determining our worldwide provision for income taxes. These determinations are highly complex and require detailed analysis of the available information and applicable statutes and regulatory materials. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be different from our historical tax practices, provisions and accruals. If we receive an adverse ruling as a result of an audit, or we unilaterally determine that we have misinterpreted provisions of the tax regulations to

71

which we are subject, our tax provision, results of operations or cash flows could be harmed. In addition, liabilities associated with taxes are often subject to an extended or indefinite statute of limitations period. Therefore, we may be subject to additional tax liability (including penalties and interest) for a particular year for extended periods of time.

If the U.S. insurance industry were to change its practice of providing incentives to homeowners for the use of alarm monitoring services, we could experience a reduction in new subscriber growth or an increase in our subscriber attrition rate.

It has been common practice in the U.S. insurance industry to provide a reduction in rates for policies written on residences that have monitored alarm systems. There can be no assurance that insurance companies will continue to offer these rate reductions. If these incentives were reduced or eliminated, new homeowners who otherwise may not feel the need for alarm monitoring services would be removed from our potential subscriber pool, which could hinder the growth of our business, and existing subscribers may choose to disconnect or not renew their service contracts, which could increase our attrition rates. In either case, our results of operations and growth prospects could be adversely affected.

Failure to comply with laws and regulations could harm our business.

We conduct our business in the United States and in various other countries. We are subject to regulation by various federal, state, local and foreign governmental agencies, including, but not limited to, agencies and regulatory bodies or authorities responsible for monitoring and enforcing product safety and consumer protection laws, data privacy and security laws and regulations, employment and labor laws, workplace safety laws and regulations, environmental laws and regulations, antitrust laws, federal securities laws and tax laws and regulations.

We are subject to the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. Travel Act, and possibly other anti-bribery laws, including those that comply with the Organization for Economic Cooperation and Development, or OECD, Convention on Combating Bribery of Foreign Public Officials in International Business Transactions and other international conventions. Anti-corruption laws are interpreted broadly and prohibit our company from authorizing, offering, or providing directly or indirectly improper payments or benefits to recipients in the public or private-sector. Certain laws also prohibit us from soliciting or accepting bribes or kickbacks. Our company has direct government interactions and in several cases uses third-party representatives, including dealers, for regulatory compliance, sales and other purposes in a variety of countries. These factors increase our anti-corruption risk profile. We can be held liable for the corrupt activities of our employees, representatives, contractors, partners and agents, even if we did not explicitly authorize such activity. Although we have implemented policies and procedures designed to ensure compliance with anti-corruption laws, there can be no assurance that all of our employees, representatives, contractors, partners, and agents will comply with these laws and policies.

Our global operations require us to import from and export to several countries, which geographically stretches our compliance obligations. We are also subject to anti-money laundering laws such as the USA PATRIOT Act and may be subject to similar laws in other jurisdictions. Our platforms and solutions are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls. Exports of our platforms and solutions must be made in compliance with these laws and regulations. We may also be subject to import/export laws and regulations in other jurisdictions in which we conduct business. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to substantial civil or criminal penalties, including the possible loss of export or import privileges; fines, which may be imposed on us and responsible employees or managers; and, in extreme cases, the incarceration of responsible employees or managers. In addition, if our service provider partners fail to obtain appropriate import, export or re-export licenses or authorizations, we may also be adversely affected through reputational harm and penalties. Obtaining the necessary authorizations, including any required license, for a particular sale may be time-consuming, is not guaranteed and may result in the delay or loss of sales opportunities. In addition, changes in our platforms or solutions or changes in applicable export or import laws and regulations may create delays in the introduction and sale of our platforms and solutions in international markets, prevent our service provider partners with international operations from deploying our platforms and solutions or, in some cases, prevent the export or import of our platforms and solutions to certain countries, governments or persons altogether. Any change in export or import laws and regulations, shift in the enforcement or scope of existing laws and regulations, or change in the countries, governments, persons or technologies targeted by such laws and regulations, could also result in decreased use of our platforms and solutions, or in our decreased ability to export or sell our platforms and solutions to existing or potential service provider partners with international operations. Any decreased use of our platforms and solutions or limitation on our ability to export or sell our platforms and solutions would likely adversely affect our business, financial condition, cash flows and results of operations.

In addition, our software contains encryption technologies, certain types of which are subject to U.S. and foreign export control regulations and, in some foreign countries, restrictions on importation and/or use. Any failure on our part to comply with encryption or other applicable export control requirements could result in financial penalties or other sanctions under the U.S. export regulations, including restrictions on future export activities, which could harm our business and operating results. Regulatory restrictions could impair our access to technologies needed to improve our platforms and solutions and may also limit or reduce the demand for our platforms and solutions outside of the United States.

72

Furthermore, U.S. export control laws and economic sanctions programs prohibit the shipment of certain products and services to countries, governments and persons that are subject to U.S. economic embargoes and trade sanctions. Even though we take precautions to prevent our platforms and solutions from being shipped or provided to U.S. sanctions targets, our platforms and solutions could be shipped to those targets or provided by third-parties despite such precautions. Any such shipment could have negative consequences, including government investigations, penalties and reputational harm. Furthermore, any new embargo or sanctions program, or any change in the countries, governments, persons or activities targeted by such programs, could result in decreased use of our platforms and solutions, or in our decreased ability to export or sell our platforms and solutions to existing or potential service provider partners, which would likely adversely affect our business, financial condition, cash flows and results of operations.

Changes in laws that apply to us could result in increased regulatory requirements and compliance costs which could harm our business, financial condition, cash flows and results of operations. In certain jurisdictions, regulatory requirements may be more stringent than in the United States. Noncompliance with applicable regulations or requirements could subject us to whistleblower complaints, investigations, sanctions, settlements, mandatory product recalls, enforcement actions, disgorgement of profits, fines, damages, civil and criminal penalties or injunctions, suspension or debarment from contracting with certain governments or other customers, the loss of export privileges, multi-jurisdictional liability, reputational harm, and other collateral consequences. If any governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, financial condition, cash flows and results of operations could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and an increase in defense costs and other professional fees. Enforcement actions and sanctions could further harm our business, financial condition, cash flows and results of operations.

We face many risks associated with our international business operations and our plans to expand internationally, which could harm our business, financial condition, cash flows and results of operations.

We anticipate that our efforts to operate and continue to expand our business internationally will entail additional costs and risks as we establish our international offerings and develop relationships with service provider partners to market, sell, install, and support our platforms, solutions and brand in other countries. Revenue in countries outside of North America accounted for 4% and 2% of our total revenue for the six months ended June 30, 2021 and 2020, respectively. We have limited experience in selling our platforms and solutions in international markets outside of North America or in conforming to the local cultures, standards, or policies necessary to successfully compete in those markets, and we may be required to invest significant resources in order to do so. We may not succeed in these efforts or achieve our consumer acquisition, service provider expansion or other goals. In some international markets, consumer preferences and buying behaviors may be different, and we may use business or pricing models that are different from our traditional model to provide our platforms and solutions to consumers in those markets or we may be unsuccessful in implementing the appropriate business model. Our revenue from new foreign markets may not exceed the costs of establishing, marketing, and maintaining our international offerings. In addition, current global instability could have many adverse consequences on our international expansion. These could include sovereign default, liquidity and capital pressures on financial institutions in other parts of the world including the eurozone, reducing the availability of credit and increasing the risk of financial sector failures and the risk of one or more eurozone member states leaving the euro, resulting in the possibility of capital and exchange controls and uncertainty about the impact of contracts and currency exchange rates.

In addition, conducting expanded international operations subjects us to additional risks that we do not generally face in our North American markets. These risks include:

•localization of our solutions, including the addition of foreign languages and adaptation to new local practices, as well as certification, registration and other regulatory requirements;

•lack of experience in other geographic markets;

•strong local competitors;

•the cost and burden of complying with, lack of familiarity with, and unexpected changes in, foreign legal and regulatory requirements, including the development of policies and procedures for different countries when requirements under privacy regulations in such countries may conflict or be inconsistent with one another;

•difficulties in managing and staffing international operations;

•increased costs due to new or potential tariffs, penalties, trade restrictions and other trade barriers, which may increase our cost of hardware revenue and reduce our hardware revenue margins in the future;

•fluctuations in currency exchange rates or restrictions on foreign currency;

73

•potentially adverse tax consequences, including the complexities of transfer pricing, value added or other tax systems, double taxation and restrictions and/or taxes on the repatriation of earnings;

•dependence on third parties, including commercial partners with whom we do not have extensive experience;

•increased financial accounting and reporting burdens and complexities;

•political, social, and economic instability, terrorist attacks, and security concerns in general; and

•reduced or varied protection for intellectual property rights in some countries.

Operating in international markets also requires significant management attention and financial resources. The investment and additional resources required to establish operations and manage growth in other countries may not produce desired levels of revenue or profitability.

Our software contains encryption technologies, certain types of which are subject to U.S. and foreign export control regulations and, in some foreign countries, restrictions on importation and/or use. Any failure on our part to comply with encryption or other applicable export control requirements could result in financial penalties or other sanctions under the U.S. export regulations, including restrictions on future export activities, which could harm our business and operating results. Regulatory restrictions could impair our access to technologies needed to improve our platforms and solutions and may also limit or reduce the demand for our platforms and solutions outside of the United States.

Enhanced United States tax, tariff, import/export restrictions, or other trade barriers may have an adverse impact on global economic conditions, financial markets and our business.

There is currently significant uncertainty about the future relationship between the United States and various other countries, including China, the European Union, Canada, and Mexico, with respect to trade policies, treaties, tariffs and customs duties, and taxes. Since 2019, the U.S. government has implemented significant changes to U.S. trade policy with respect to China. Tariffs have subjected certain Alarm.com products manufactured overseas to additional import duties of up to 25%. The amount of the import tariff and the number of products subject to tariffs have changed numerous times based on action by the U.S. government. We are addressing the risks related to these imposed and announced tariffs, which have affected, or have the potential to affect, at least some of our imports from China.

Between one-fifth to one-half of the hardware products that we sell to our customers are imported from China and could be subject to increased tariffs. Other Alarm.com hardware products that are not manufactured in China may contain subcomponents made in China that could also be subject to increased tariffs. While the additional import duties have resulted in an increase to our cost of hardware revenue, these import duties had a modest impact on hardware revenue margins. If tariffs, trade restrictions, or trade barriers are expanded or interpreted by a court or governmental agency to apply to more of our products, then our exposure to future taxes and duties on such imported products and components could be significant and could have a material effect on our financial results. If our products are deemed to be subject to additional duties and taxes as determined by a court or governmental agency, we may suffer additional hardware revenue margin erosion or be required to raise our prices on certain imported products. There can be no assurance that we will not experience a disruption in our business or harm to our financial condition related to these or other changes in trade practices, and any changes to our operations or our sourcing strategy in order to mitigate any such tariff costs could be complicated, time-consuming, and costly. Furthermore, our business may be adversely affected by retaliatory trade measures taken by China and other countries, which could materially harm our business, financial condition and results of operations. Trade barriers, or the perception that any of them could be imposed, may have a negative effect on global economic conditions and the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between these nations and the United States. Any of these factors could have a material adverse effect on our business, financial condition and results of operations.

On June 17, 2021, the U.S. Federal Communications Commission, or the FCC, adopted a proposed rule that would effectively ban in the United States all communications equipment provided by entities identified on a “Covered List” that it maintains pursuant to the Secure and Trusted Communications Networks Act of 2019. The Covered List currently consists of video surveillance and telecommunications equipment produced by five Chinese electronics companies, including one of our suppliers. Although the proposed rule does not include language regarding retroactive application of the proposed ban, the FCC has asked for comment on whether and under what circumstances it should revoke existing authorizations of communications equipment from companies on the Covered List. If the final rule issued by the FCC restricts our ability to sell any of our existing inventory of products on the Covered List or applies retroactively to products already sold, this would likely adversely affect our business, financial condition, cash flows and results of operations.

Our financial results may be adversely affected by changes in accounting principles applicable to us.

Our accounting policies are critical to the manner in which we present our results of operations and financial condition. Many of these policies are highly complex and involve many assumptions, estimates and judgments. A change in accounting standards or practices, in particular with respect to revenue recognition, could harm our operating results and may even affect our reporting

74

of transactions completed before the change is effective. GAAP rules are subject to interpretation by the Financial Accounting Standards Board, or FASB, the SEC and other various bodies formed to promulgate and interpret appropriate accounting principles. See Note 2 to our condensed consolidated financial statements for new accounting pronouncements. Implementation of new accounting standards could have a significant effect on our financial results, and any difficulties in implementing these pronouncements could cause us to fail to meet our financial reporting obligations, which could result in regulatory discipline and harm investors’ confidence in us.

Our accounting is becoming more complex, and relies upon estimates or judgments relating to our critical accounting policies. If our accounting is erroneous or based on assumptions that change or prove to be incorrect, our operating results could fall below the expectations of securities analysts and investors, resulting in a decline in our stock price.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes, and also to comply with many complex requirements and standards. Because of the use of estimates inherent in the financial reporting process, actual results could differ from those estimates and any such differences may be material. We devote substantial resources to compliance with accounting requirements and we base our estimates on our best judgment, historical experience, information derived from third parties, and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue and expenses that are not readily apparent from other sources. However, various factors are causing our accounting to become complex. Ongoing evolution of our business, and the COVID-19 pandemic and resulting uncertainty have, and any future acquisitions may, compound these complexities. Our operating results may be adversely affected if we make accounting errors or our judgments prove to be wrong, assumptions change or actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of securities analysts and investors or guidance we may have provided, resulting in a decline in our stock price and potential legal claims. Significant judgments, assumptions and estimates used in preparing our condensed consolidated financial statements include those related to revenue recognition, stock-based compensation, business combinations, and income taxes.

Risks Related to Our Intellectual Property

If we fail to protect our intellectual property and proprietary rights adequately, our business could be harmed.

We believe that our proprietary technology is essential to establishing and maintaining our leadership position. We seek to protect our intellectual property through trade secrets, copyrights, confidentiality, non-compete and nondisclosure agreements, patents, trademarks, domain names and other measures, some of which afford only limited protection. We also rely on patent, trademark, trade secret and copyright laws to protect our intellectual property. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our technology or to obtain and use information that we regard as proprietary. Our means of protecting our proprietary rights may not be adequate or our competitors may independently develop similar or superior technology, or design around our intellectual property. In addition, the laws of some foreign countries do not protect our proprietary rights to as great an extent as the laws of the United States. Intellectual property protections may also be unavailable, limited or difficult to enforce in some countries, which could make it easier for competitors to capture market share. Our failure or inability to adequately protect our intellectual property and proprietary rights could harm our business, financial condition, cash flows and results of operations.

To prevent substantial unauthorized use of our intellectual property rights, it may be necessary to prosecute actions for infringement and/or misappropriation of our proprietary rights against third parties. See the section of this Quarterly Report titled "Legal Proceedings" for additional information on related intellectual property litigation matters. Any such action could result in significant costs and diversion of our resources and management's attention, and we cannot assure you that we will be successful in such action. Furthermore, many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights than we do. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property.

An assertion by a third party that we are infringing its intellectual property could subject us to costly and time-consuming litigation or expensive licenses that could harm our business and results of operations.

The industries in which we compete are characterized by the existence of a large number of patents, copyrights, trademarks and trade secrets, and by frequent litigation based on allegations of infringement or other violations of intellectual property rights. We have been involved with patent litigation suits in the past and we may be involved with and subject to similar litigation in the future to defend our intellectual property position. For example, on June 2, 2015, Vivint filed a lawsuit against us in U.S. District Court, District of Utah, alleging that our technology directly and indirectly infringes six patents that Vivint purchased. Vivint is seeking permanent injunctions, enhanced damages and attorneys' fees. Should Vivint prevail on its claims that one or more elements of our solution infringe one or more of its patents, we could be required to pay damages of Vivint’s lost profits and/or a reasonable royalty for sales of our solution, enjoined from making, using, and selling our solution if a license or other right to continue selling such elements is not made available to us or we are unable to design around such patents, and required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to Vivint’s claims, any of these outcomes could result in a material adverse effect on our business.

75

In addition, on November 11, 2019, EcoFactor filed a lawsuit against us in the U.S. District Court, District of Massachusetts, alleging that our smart thermostats infringe three U.S. patents owned by EcoFactor, seeking permanent injunctions, enhanced damages and attorneys' fees. On May 26, 2020, EcoFactor filed a second lawsuit against us in U.S. District Court, District of Massachusetts, alleging Alarm.com’s products and services infringe four additional U.S. patents owned by EcoFactor. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. See the section of this Quarterly Report titled "Legal Proceedings" for additional information on each of these matters. Should EcoFactor prevail in either of its district court lawsuits we could be required to pay damages in the amount of EcoFactor’s lost profits and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us or we are unable to design around such patents, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to EcoFactor’s claims, any of these outcomes could result in a material adverse effect on our business.

On July 22, 2021, Causam filed a lawsuit against us in U.S. District Court, Western District of Texas, alleging that Alarm.com’s smart thermostats infringe four U.S. patents owned by Causam. Causam is seeking preliminary and permanent injunctions, enhanced damages and attorneys’ fees. On July 28, 2021, Causam filed a complaint with the ITC alleging infringement of the same four patents. Causam is seeking a permanent limited exclusion order and permanent cease and desist order. See the section of this Quarterly Report titled "Legal Proceedings" for additional information on each of these matters. Should Causam prevail in an ITC investigation, Alarm.com thermostats manufactured abroad could be excluded from importation into the United States. Should Causam prevail in its district court lawsuit we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to Causam’s claims, the outcome of these legal claims cannot be predicted with certainty, and any of these outcomes could result in an adverse effect on our business.

Even if we were to prevail in any of these matters, ongoing litigation could continue to be costly and time-consuming, divert the attention of our management and key personnel from our business operations and dissuade potential customers from purchasing our solution, which would also materially harm our business. During the course of each of these litigation matters, we anticipate announcements of the results of hearings and motions, and other interim developments related to the litigation matters at hand. If securities analysts or investors regard these announcements as negative, the market price of our common stock may decline.

We might not prevail in any intellectual property infringement litigation given the complex technical issues and inherent uncertainties in such litigation and our service provider partner contracts may require us to indemnify them against certain liabilities they may incur as a result of our infringement or alleged infringement of any third party intellectual property. Defending such claims, regardless of their merit, could be time-consuming and distracting to management, result in costly litigation or settlement, cause development delays or require us to enter into royalty or licensing agreements. In addition, we currently have a limited portfolio of issued patents compared to our larger competitors, and therefore may not be able to effectively utilize our intellectual property portfolio to assert defenses or counterclaims in response to patent infringement claims or litigation brought against us by third parties. Further, litigation may involve patent holding companies or other adverse patent owners who have no relevant products or revenues and against which our potential patents provide no deterrence, and many other potential litigants have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. Given that our platforms and solutions integrate with many aspects of a property, the risk that our platforms and solutions may be subject to these allegations is exacerbated. As we seek to extend our platforms and solutions, we could be constrained by the intellectual property rights of others. If our platforms and solutions exceed the scope of in-bound licenses or violate any third party proprietary rights, we could be required to withdraw those solutions from the market, re-develop those solutions or seek to obtain licenses from third parties, which might not be available on reasonable terms or at all. Any efforts to re-develop our platforms and solutions, obtain licenses from third parties on favorable terms or license a substitute technology might not be successful and, in any case, might substantially increase our costs and harm our business, financial condition, cash flows and results of operations. If we were compelled to withdraw any of our platforms and solutions from the market, our business, financial condition, cash flows and results of operations could be harmed.

We have indemnity obligations to certain of our service provider partners for certain expenses and liabilities resulting from intellectual property infringement claims regarding our platforms and solutions, which could force us to incur substantial costs.

We have indemnity obligations to certain of our service provider partners for intellectual property infringement claims regarding our platforms and solutions. As a result, in the case of infringement claims against these service provider partners, we could be required to indemnify them for losses resulting from such claims or to refund amounts they have paid to us. We expect that some of our service provider partners may seek indemnification from us in connection with infringement claims brought against them. In addition, we may elect to indemnify service provider partners where we have no contractual obligation to indemnify them and we will evaluate each such request on a case-by-case basis. If a service provider partner elects to invest resources in enforcing a claim for indemnification against us, we could incur significant costs disputing it. If we do not succeed in

76

disputing it, we could face substantial liability. See the section of this Quarterly Report titled "Legal Proceedings" for additional information regarding this matter and the other legal proceedings we are involved in.

The use of open source software in our platforms and solutions may expose us to additional risks and harm our intellectual property.

Some of our platforms and solutions use or incorporate software that is subject to one or more open source licenses and we may incorporate open source software in the future. Open source software is typically freely accessible, usable and modifiable. Certain open source software licenses require a user who intends to distribute the open source software as a component of the user's software to disclose publicly part or all of the source code to the user's software. In addition, certain open source software licenses require the user of such software to make any derivative works of the open source code available to others on potentially unfavorable terms to us or at no cost.

The terms of many open source licenses to which we are subject have not been interpreted by U.S. or foreign courts, and accordingly there is a risk that those licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to commercialize our platforms and solutions. In that event, we could be required to seek licenses from third parties in order to continue offering our platforms and solutions, to re-develop our platforms and solutions, to discontinue sales of our platforms and solutions or to release our proprietary software code under the terms of an open source license, any of which could harm our business. Further, given the nature of open source software, it may be more likely that third parties might assert copyright and other intellectual property infringement claims against us based on our use of these open source software programs. Litigation could be costly for us to defend, have a negative effect on our business, financial condition, cash flows and results of operations or require us to devote additional research and development resources to change our solutions.

Although we are not aware of any use of open source software in our platforms and solutions that would require us to disclose all or a portion of the source code underlying our core solutions, it is possible that such use may have inadvertently occurred in deploying our platforms and solutions. Additionally, if a third party software provider has incorporated certain types of open source software into software we license from such third party for our platforms and solutions without our knowledge, we could, under certain circumstances, be required to disclose the source code to our platforms and solutions. This could harm our intellectual property position as well as our business, financial condition, cash flows and results of operations.

Risks Related to Ownership of Our Common Stock

The market price of our common stock has been and will likely continue to be volatile.

The market price of our common stock may be highly volatile and may fluctuate substantially as a result of a variety of factors, some of which are related in complex ways. The market price of our common stock may decline regardless of our operating performance, resulting in the potential for substantial losses for our stockholders, and may fluctuate significantly in response to numerous factors, many of which are beyond our control, including the factors listed below and other factors described in this "Risk Factors" section:

•actual or anticipated fluctuations in our financial condition and operating results;

•the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

•failure of securities analysts to initiate or maintain coverage of our company, changes in financial estimates by any securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;

•ratings changes by any securities analysts who follow our company;

•variance in our financial performance from expectations of securities analysts;

•announcements by us or our competitors of significant business developments, technical innovations, acquisitions or new solutions;

•changes in the prices of our platforms and solutions;

•changes in our projected operating and financial results;

•changes in laws or regulations applicable to our platforms and solutions or marketing techniques, or our industry in general;

•repurchases of our common stock under the stock repurchase program authorized by our board of directors or our sale of our common stock or other securities in the future;

•changes in senior management or key personnel;

•trading volume of our common stock;

•changes in the anticipated future size and growth rate of our market; and

•general economic, regulatory and market conditions in the United States and abroad as well as the uncertainty resulting from the COVID-19 pandemic.

The stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry fluctuations, as well as general economic, political, regulatory and market conditions, may negatively impact the market price of our common stock. In the past, companies that have experienced volatility in the market price of their securities have been subject to securities class action litigation. We may be the target of this type of litigation in the future, which could result in substantial costs and divert our management’s attention.

Sales of a substantial number of shares of our common stock in the public market could cause our market price to decline.

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales, particularly sales by our directors, executive officers, and significant stockholders, may have on the prevailing market price of our common stock. Additionally, the shares of common stock subject to outstanding options under our equity incentive plans and the shares reserved for future issuance under our equity incentive plans, as well as shares issuable upon vesting of restricted stock awards, will become eligible for sale in the public market in the future, subject to certain legal and contractual limitations. Moreover, some holders of shares of our common stock have rights, subject to certain conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or our stockholders. We have also registered shares of common stock that we may issue under our employee equity incentive plans. Accordingly, these shares may be able to be sold freely in the public market upon issuance as permitted by any applicable vesting requirements. See “Conversion of the 2026 Notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock” below for further details on the risks related to the dilutive impact of the 2026 Notes.

We are obligated to develop and maintain a system of effective internal controls over financial reporting. These internal controls may be determined to be not effective, which may adversely affect investor confidence in our company and, as a result, the value of our common stock.

We have been and are required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting on an annual basis. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal controls are effective and would be required to disclose any material weaknesses identified in Management’s Report on Internal Control over Financial Reporting. While we have established certain procedures and control over our financial reporting processes, we cannot assure you that these efforts will prevent restatements of our financial statements in the future.

Our independent registered public accounting firm is also required, pursuant to Section 404 of the Sarbanes-Oxley Act, to report on the effectiveness of our internal control over financial reporting. For future reporting periods, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. We may not be able to remediate any future material weaknesses, or to complete our evaluation, testing and any required remediation in a timely fashion.

If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion that our internal controls over financial reporting are effective, investors could lose confidence in the accuracy and completeness of our financial reports, which could cause the price of our common stock to decline, and we could be subject to sanctions or investigations by regulatory authorities, including the SEC and Nasdaq. Failure to remediate any material weakness in our internal control over financial reporting, or to maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

78

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our share price and trading volume could decline.

The trading market for our common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If our financial performance fails to meet analyst estimates or one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our board of directors and may be subject to any restrictions on paying dividends in any future indebtedness. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.

Provisions in our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing a change in control or changes in our management. Our amended and restated certificate of incorporation and amended and restated bylaws include provisions that:

•authorize our board of directors to issue preferred stock, without further stockholder action and with voting liquidation, dividend and other rights superior to our common stock;

•require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent, and limit the ability of our stockholders to call special meetings;

•establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations of persons for director nominees;

•prohibit cumulative voting in the election of directors; and

•provide that vacancies on our board of directors may be filled only by the vote of a majority of directors then in office, even though less than a quorum.

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any "interested" stockholder for a period of three years following the date on which the stockholder became an "interested" stockholder. Any of the foregoing provisions could limit the price that investors might be willing to pay in the future for shares of our common stock, and they could deter potential acquirers of our company, thereby reducing the likelihood that you would receive a premium for your common stock in an acquisition.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us.

Pursuant to our amended and restated certificate of incorporation, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (3) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws or (4) any action asserting a claim governed by the internal affairs doctrine. Notwithstanding the foregoing, this choice of forum provision will not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction. Furthermore, Section 22 of the Securities Act of 1933, as amended, creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. Our amended and restated certificate of incorporation provides that any person or entity purchasing or otherwise acquiring any interest in shares of our common stock is deemed to have notice of and consented

79

to the foregoing provision. The forum selection clause in our amended and restated certificate of incorporation may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us.

Risks Related to our Outstanding Convertible Senior Notes

We may not have the ability to raise the funds necessary to settle cash conversions of the 2026 Notes or to repurchase the 2026 Notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the 2026 Notes.

On January 20, 2021, we issued the 2026 Notes. The terms of the 2026 Notes are governed by an Indenture, or the Indenture, by and between Alarm.com Holdings, Inc. and U.S. Bank National Association, as trustee. The 2026 Notes are senior unsecured obligations that do not bear regular interest and the principal amount of the 2026 Notes will not accrete. The 2026 Notes may bear special interest under specified circumstances related to our failure to comply with our reporting obligations under the Indenture. Special interest, if any, will be payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2021. We received proceeds from the issuance of the 2026 Notes of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs. Holders of the 2026 Notes will have the right, subject to certain conditions and limited exceptions, to require us to repurchase all or a portion of their notes upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid special interest, if any, as defined in the Indenture. In addition, upon conversion of the 2026 Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the 2026 Notes being converted as defined in the Indenture. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of 2026 Notes surrendered therefor or pay cash with respect to 2026 Notes being converted. In addition, our ability to repurchase the 2026 Notes or to pay cash upon conversions of the 2026 Notes may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase the 2026 Notes at a time when the repurchase is required by the Indenture or to pay any cash payable on future conversions of the 2026 Notes as required by the Indenture would constitute a default under the Indenture. A default under the Indenture governing the 2026 Notes or the fundamental change itself could also lead to a default under agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the 2026 Notes or make cash payments upon conversions thereof.

The conditional conversion feature of the 2026 Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the 2026 Notes is triggered, holders of 2026 Notes will be entitled to convert the 2026 Notes at any time during specified periods at their option. If one or more holders elect to convert their 2026 Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

Conversion of the 2026 Notes may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock.

The conversion of some or all of the 2026 Notes may dilute the ownership interests of our stockholders. Upon conversion of the 2026 Notes, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock. If we elect to settle our conversion obligation in shares of our common stock or a combination of cash and shares of our common stock, any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the 2026 Notes may encourage short selling by market participants because the conversion of the 2026 Notes could be used to satisfy short positions, or anticipated conversion of the 2026 Notes into shares of our common stock could depress the price of our common stock.

Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include our accounts and those of our majority-owned and controlled subsidiaries after elimination of intercompany accounts and transactions.

These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual financial statements. They should be read together with our audited consolidated financial statements and related notes thereto for the year ended December 31, 2020 included in our Annual Report on Form 10-K filed with the SEC on February 25, 2021, or the Annual Report. The condensed consolidated balance sheet as of December 31, 2020 was derived from our audited financial statements, but does not include all disclosures required by GAAP for annual financial statements.

In the opinion of management, these condensed consolidated financial statements include all normal recurring adjustments necessary for a fair statement of the results of operations, financial position and cash flows for the periods presented. However, the COVID-19 pandemic disrupted and may continue to disrupt our supply chain for an unknown period of time due to its impact on manufacturing, production and global transportation. The COVID-19 pandemic also disrupted and may intermittently continue to disrupt our sales channels due to restrictions imposed from time to time on our service providers’ ability to meet with residential and commercial property owners who use our solutions. In addition, the COVID-19 pandemic resulted in a global slowdown of economic activity and a recession in the United States and the economic situation remains fluid as parts of the economy appear to be recovering while others continue to struggle. While vaccines have been approved for use in the United States and in many other countries, and vaccination efforts are underway, it remains difficult to assess or predict the ultimate duration and economic impact of the COVID-19 pandemic. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results that can be expected for our entire fiscal year ending December 31, 2021, which is increasingly true in periods of extreme uncertainty, such as the uncertainty caused by the COVID-19 pandemic. Prolonged uncertainty with respect to COVID-19 could cause further economic slowdown or cause other unpredictable events, each of which could adversely affect our business, results of operations or financial condition.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. As of the date of issuance of these financial statements, we are not aware of any specific event or circumstance that would require us to update our estimates, assumptions and judgments or revise the carrying value of our assets or liabilities. However, our estimates, judgments and assumptions are continually evaluated based on available information and experience and may change as new events occur and additional information is obtained. Because of the use of estimates inherent in the financial reporting process and in light of the continuing uncertainty arising from the COVID-19 pandemic, actual results could differ from those estimates and any such differences may be material. Estimates are used when accounting for revenue recognition, allowances for credit losses, allowance for hardware returns, estimates of obsolete inventory, long-term incentive compensation, the lease term and incremental borrowing rates for leases, stock-based compensation, income taxes, legal reserves, fair value of the debt component of convertible notes, contingent consideration and goodwill and intangible assets.

Comprehensive Income

Our comprehensive income for the three and six months ended June 30, 2021 and 2020 was equal to our net income disclosed in the condensed consolidated statements of operations.

Significant Accounting Policies

Other than those disclosed herein, there have been no other material changes to our significant accounting policies during the three and six months ended June 30, 2021 from those disclosed in our Annual Report.

Convertible Senior Notes

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes in a private placement to qualified institutional buyers due January 15, 2026. In accounting for the issuance of our convertible senior notes, we separate the notes into liability and equity components. The carrying amount of the liability component is calculated by measuring the fair value of a similar liability that does not have an associated convertible feature, using a discounted cash flow model with a risk adjusted yield. The carrying amount of the equity component representing the conversion option is determined by deducting the fair value of the liability component from the par value of the notes as a whole. This difference represents a debt discount that is amortized to interest expense using the effective interest method over the term of the notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the transaction costs related to the issuance of the notes, we allocate the total amount incurred to the liability and equity components using the same proportions as the proceeds from the notes. Transaction costs attributable to the liability component are netted with the liability component and amortized to interest expense using the effective interest method over the term of the notes. Transaction costs attributable to the equity component are netted with the equity component of the notes in additional paid-in capital in the condensed consolidated balance sheets. See Note 12 for the carrying amount and estimated fair value of our convertible senior notes as of June 30, 2021.

Recent Accounting Pronouncements

Adopted

On December 18, 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes," which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The update also simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance to improve consistent application. The amendment in this update was effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. On January 1, 2021, we adopted Topic 740. This pronouncement did not have a material impact on our condensed consolidated financial statements or disclosures.

Not Yet Adopted

On March 12, 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued such as the Eurodollar Base Rate, or LIBOR. The update allows entities to elect not to apply certain modification accounting requirements to contracts affected by the discontinuation of a reference rate if certain criteria are met. The amendment was effective beginning March 12, 2020 and will continue to be effective through December 31, 2022. Due to the termination of our credit facility on January 20, 2021 (see Note 12), this pronouncement is not expected to have an impact on our condensed consolidated financial statements or disclosures.

On August 5, 2020, the FASB issued ASU 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity," which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The new guidance eliminates two of the three models in Subtopic 470-20 that require separating embedded conversion features from convertible instruments. The guidance also addresses how convertible instruments are accounted for in the diluted earnings per share calculation. The amendment in this update is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The guidance allows for either full retrospective adoption or modified retrospective adoption. We are currently assessing the impact this pronouncement may have on our consolidated financial statements when we adopt the pronouncement on January 1, 2022.

Revenue from Contracts with Customers

6 Months Ended

Jun. 30, 2021

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Revenue from Contracts with Customers

Revenue Recognition

We derive our revenue from three primary sources: the sale of cloud-based SaaS services on our integrated Alarm.com platform, the sale of licenses and services on our non-hosted software platform, or Software platform, and the sale of hardware products. We sell our platform and hardware solutions to service provider partners that resell our solutions and hardware to residential and commercial property owners, who are the service provider partners’ customers. Our subscribers consist of all of the properties maintained by those residential and commercial property owners to which we are delivering at least one of our solutions. We also sell our hardware to distributors who resell the hardware to service provider partners. We enter into contracts with our service provider partners that establish pricing for access to our platform solutions and for the sale of hardware. These service provider contracts typically have an initial term of one year, with subsequent renewal terms of one year. Our service provider partners typically enter into contracts with our subscribers, which our service provider partners have indicated range from three to five years in length.

When determining the amount of consideration we expect to be entitled to for the sale of our hardware, we estimate the variable consideration associated with customer returns. We record a reserve against revenue for hardware returns based on historical returns. For the twelve months ended June 30, 2021 and 2020, our reserve against revenue for hardware returns was 1%. We evaluate our hardware reserve on a quarterly basis or if there is an indication of significant changes in return experience. Historically, our returns of hardware have not significantly differed from our estimated reserve. Additionally, we provide warranties related to the intended functionality of the products and services provided and those warranties typically allow for the return of hardware up to one year past the date of sale. We determined that these warranties are not separate performance obligations as they cannot be purchased separately and do not provide a service in addition to an assurance the hardware will function as expected.

Our hardware and other revenue also includes our revenue from the sale of perpetual licenses that provide our customers in the commercial market the right to use our OpenEye video surveillance software for an indefinite period of time in exchange for a one-time license fee, which is generally paid at contract inception. Our hardware and other revenue also includes our revenue from Shooter Detection Systems related to the sale of licenses that provide our customers the right to use our indoor gunshot detection solution in exchange for license fees, which are generally paid at contract inception. Our perpetual licenses and licenses to our indoor gunshot detection solution provide a right to use intellectual property that is functional in nature and has significant stand-alone functionality. Accordingly, for licenses of functional intellectual property, revenue is recognized at the point-in-time when control has been transferred to the customer, which occurs once the software has been made available to the customer.

Hardware and other revenue may also include activation fees charged to some of our service provider partners for activation of a new subscriber account on our platforms, as well as fees paid by service provider partners for our marketing services. Our service provider partners use services on our platforms, such as support tools and applications, to assist in the installation of our solutions in subscriber properties. This installation marks the beginning of the service period on our platforms and, on occasion, we earn activation revenue for fees charged for this service. The activation fee is non-refundable, separately negotiated and specified in our contractual arrangements with our service provider partners and is charged to the service provider partner for each subscriber activated on our platforms. The decision whether to charge an activation fee is based in part on the expected number of subscribers to be added by our service provider partners and as a result, many of our largest service provider partners do not pay an activation fee. Activation fees are not offered on a stand-alone basis separate from our SaaS offering and are billed and received at the beginning of the arrangement. We record activation fees initially as deferred revenue and we recognize these fees ratably over the expected term of the subscribers’ account which we estimate is ten years based on our annual attrition rate. The portion of these activation fees included in current and long-term deferred revenue as of our balance sheet date represents the amounts that will be recognized ratably as revenue over the following twelve months, or longer as appropriate, until the ten-year expected term is complete. The balance of deferred revenue for activation fees was $6.5 million and $7.0 million as of June 30, 2021 and December 31, 2020, respectively, which combines current and long-term balances.

SaaS and license revenue associated with our contracts is invoiced and revenue is recognized at an amount that corresponds directly with the value of the performance completed to date. Additionally, the consideration received from hardware sales corresponds directly with the stand-alone selling price of the hardware. As a result, we have elected to use the practical expedient related to the amount of transaction price allocated to the unsatisfied performance obligations and therefore, we have not disclosed the total remaining revenue expected to be recognized on all contracts or the expected period over which the remaining revenue would be recognized. 

Contract Assets

At contract inception, we assess the goods and services promised in our contracts with customers and identify a performance obligation for each distinct promise to transfer a good or service, or bundle of goods or services. To identify the performance obligations, we consider all of the goods or services promised in the contract, whether explicitly stated or implied

based on customary business practices. We record a contract asset when we satisfy a performance obligation by transferring a promised good or service. Contract assets can be conditional or unconditional depending on whether another performance obligation must be satisfied before payment can be received. We receive payments from our service provider partners based on the billing schedule established in our contracts. All of the accounts receivable presented in the condensed consolidated balance sheets represent unconditional rights to consideration. We do not have any assets from contracts containing conditional rights and we do not have any assets from satisfied performance obligations that have not been invoiced.

We recognize an asset related to the costs incurred to obtain a contract only if we expect to recover those costs and we would not have incurred those costs if the contract had not been obtained. We recognize an asset from the costs incurred to fulfill a contract if the costs (i) are specifically identifiable to a contract, (ii) enhance resources that will be used in satisfying performance obligations in future and (iii) are expected to be recovered. Our contract assets consist of capitalized commission costs and upfront payments made to a customer. Based on the policy above, we capitalize a portion of our commission costs as an incremental cost of obtaining a contract. When calculating the incremental cost of obtaining a contract, we exclude any commission costs related to metrics that could be satisfied without obtaining a contract, including training-related metrics. We amortize our commission costs over a period of three years, which is consistent with the period over which the products and services related to the commission are transferred to the customer. The three-year period was determined based on our review of historical enhancements and upgrades to our products and services. We applied the portfolio approach to account for the amortization of contract costs for those contracts that have similar characteristics. Upfront payments made to a customer are capitalized and amortized over the expected period of benefit and are recorded as a reduction to revenue.

The current portion of capitalized commission costs and upfront payments made to customers are included in other current assets within our condensed consolidated balance sheets. The non-current portion of capitalized commission costs and upfront payments made to customers are reflected in other assets within our condensed consolidated balance sheets.

We review the capitalized costs for impairment at least annually. Impairment exists if the carrying amount of the asset recognized from contract costs exceeds the remaining amount of consideration we expect to receive in exchange for providing the goods and services to which such asset relates, less the costs that relate directly to providing those good and services and that have not been recognized as an expense. We did not record an impairment loss on our contract assets during the three and six months ended June 30, 2021 and 2020.

Contract Liabilities

Contract liabilities include payments received in advance of performance under the contract and are realized with the associated revenue recognized under the contract. All of the deferred revenue presented in the condensed consolidated balance sheets represents contract liabilities resulting from advance cash receipts from customers or amounts billed in advance to customers from the sale of services. Changes in deferred revenue are due to our performance under the contract as well as to cash received from new contracts for which services have not been provided.

Accounts receivable, net	$	92,612	$	83,326

For the three and six months ended June 30, 2021, we recorded a provision for credit losses of $0.1 million and $0.2 million on our accounts receivable, respectively. For the three months ended June 30, 2020, we recorded a reduction to the provision for credit losses of $0.9 million on our accounts receivable. For the six months ended June 30, 2020, we recorded a provision for credit losses of $1.0 million on our accounts receivable.

For the three and six months ended June 30, 2021, we recorded a reserve for product returns of $0.5 million and $1.1 million, respectively, as compared to $0.7 million and $1.0 million for the same periods in the prior year. Historically, we have not experienced write-offs for uncollectible accounts or sales returns that have differed significantly from our estimates.

Allowance for Credit Losses - Accounts Receivable

The allowance for credit losses is a valuation account that is deducted from the accounts receivable and notes receivable amortized cost basis (see Note 8) to present the net amount expected to be collected. We estimate the allowance balance by applying the loss-rate method using relevant available information from internal and external sources, including historical write-off activity, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for changes in economic conditions, such as changes in unemployment rates. We use projected economic conditions over a period no more than twelve months based on data from external sources. For periods beyond the twelve-month reasonable and supportable forecast period, we revert to historical loss information immediately.

The allowance for credit losses is measured on a pooled basis when similar risk characteristics exist. When assessing whether to measure certain financial assets on a pooled basis, we considered various risk characteristics, including the financial asset type, size and the historical or expected credit loss pattern. We identified the following two portfolio segments for our accounts receivable: (i) outstanding accounts receivable balances within Alarm.com and certain subsidiaries and (ii) outstanding accounts receivable balances within all other subsidiaries. There were no changes to our portfolio segments for our accounts receivable during the three and six months ended June 30, 2021, and no changes to our policies or practices that influenced our estimate of expected credit losses for accounts receivable. There were no significant changes in the amount of accounts receivable write-offs during the three and six months ended June 30, 2021, as compared to historical periods other than a partial write-off of $0.7 million related to one of our distribution partners' outstanding balance during the six months ended June 30, 2021, upon the distributor being acquired by a third party.

Expected credit losses are estimated over the contractual term of the financial assets and we adjust the term for expected prepayments when appropriate. For the three and six months ended June 30, 2021, we recorded credit loss expense for accounts receivable and notes receivable of $0.1 million and less than $0.1 million, respectively, in general and administrative expense in our condensed consolidated statements of operations. For the three months ended June 30, 2020, we recorded a reduction of credit loss expense of $0.9 million and for the six months ended June 30, 2020, we recorded credit loss expense of $0.5 million in general and administrative expense in our condensed consolidated statements of operations. The contractual term excludes expected extensions, renewals and modifications because extension and renewal options are unconditionally cancelable by us. Write-offs of the amortized cost basis are recorded to the allowance for credit losses. Any subsequent recoveries of previously written off balances are recorded as a reduction to credit loss expense.

Asset Acquisitions

On March 12, 2020, Alarm.com Incorporated, one of our wholly-owned subsidiaries, acquired certain assets of an unrelated third party. Substantially all of the acquired assets consisted of in-process research and development, or IPR&D. We believe the acquisition of the IPR&D will continue to strengthen our smart intercom capability, including building access security and convenience within the multiple dwelling unit market for residents, guests and deliveries.

In consideration for the purchase of the IPR&D, we paid $1.2 million in cash on March 12, 2020, with the remaining $0.3 million expected to be paid 18 months following the acquisition date, subject to offset for any indemnification obligations. The $1.5 million consideration related to IPR&D was expensed at the time of the asset acquisition and was included in research and development expense in our condensed consolidated statements of operations during the six months ended June 30, 2020, as the IPR&D had no alternative future use.

On March 31, 2020, Alarm.com Incorporated acquired certain assets of an unrelated third party. Substantially all of the acquired assets consisted of IPR&D. We believe the acquisition of the IPR&D will continue to further our commitment to make significant investments in innovative research and development in the intelligently connected property market to broaden our suite of solutions.

In consideration for the purchase of the IPR&D, we paid $2.1 million in cash on March 31, 2020, $0.1 million in December 2019 and the remaining $0.7 million in April 2021. The $2.9 million consideration related to IPR&D was expensed at the time of the asset acquisition and was included in research and development expense in our condensed consolidated statements of operations during the six months ended June 30, 2020, as the IPR&D had no alternative future use.

Acquisition of a Business - Shooter Detection Systems

On December 14, 2020, Alarm.com Incorporated acquired 100% of the issued and outstanding ownership interest units of Shooter Detection Systems, LLC, or SDS. SDS provides an indoor gunshot detection solution through the Guardian Indoor Active Shooter Detection System, which uses a combination of acoustic and infrared sensors and proprietary algorithms to detect gunshots and communicate shooting incident details to building occupants and security teams. The acquisition of SDS expands our commercial solutions and helps our partners outfit commercial and enterprise customers with the indoor gunshot detection solution.

In consideration for the purchase of 100% of the issued and outstanding ownership interest units of SDS, we paid $26.6 million in cash on December 14, 2020. Pursuant to the terms of the unit purchase agreement, following the preliminary determination of the working capital of SDS as of the closing date, the purchase price decreased by $0.1 million. The purchase price allocation was finalized during the second quarter of 2021, including the working capital adjustment, resulting in a measurement period adjustment to increase the purchase consideration by $0.1 million and to increase goodwill by $0.1 million.

The table below sets forth the purchase consideration and the fair value allocation of the tangible and intangible net assets acquired (in thousands):

	December 14, 2020
Calculation of Purchase Consideration:
Cash paid, net of working capital adjustment	$	26,577
Total consideration	$	26,577
Tangible and Intangible Net Assets:
Cash	$	311
Accounts receivable	1,179
Inventory	917
Other current assets	240

Accounts payable	(19)
Accrued expenses	(111)
Operating lease current liabilities	(51)
Operating lease liabilities	(333)
Goodwill	7,239
Total tangible and intangible net assets	$	26,577

Goodwill of $7.2 million reflects the value of acquired workforce and synergies we expect to achieve from expanding our commercial solutions through SDS's indoor gunshot detection solution. The goodwill recognized is expected to be deductible for income tax purposes in future periods. We allocate goodwill to reporting units based on expected benefit from synergies and have allocated the goodwill to the Alarm.com segment.

Fair Value of Net Assets Acquired and Intangibles

In accordance with Accounting Standards Codification, or ASC, 805, Business Combinations, SDS constituted a business and the assets and liabilities were recorded at their respective fair values as of December 14, 2020. We developed our estimate of the fair value of intangible net assets using the with-and-without method for customer relationships, the multi-period excess earnings method for the developed technology and the relief-from-royalty method for the trade name.

Customer Relationships

We recorded the customer relationships intangible separately from goodwill based on determination of the length, strength and contractual nature of the relationship that SDS shared with its customers. We valued the single group of customer relationships using the with-and-without method, an income approach. The significant assumptions used in the with-and-without method include estimates about future expected cash flows from customer contracts and the discount rate. We are amortizing the customer relationships, valued at $2.4 million, on an attribution basis derived from the discounted cash flows of the model over an estimated useful life of six years.

Developed Technology

Developed technology primarily consists of intellectual property of proprietary software that is marketed for sale. We valued the developed technology by applying the multi-period excess earnings method, an income approach. The significant assumptions used in the multi-period excess earnings method include estimates about future expected cash flows from the developed technology, the obsolescence factor and the discount rate. We are amortizing the SDS developed technology, valued at $13.5 million, on an attribution method based on the discounted cash flows of the model over an estimated useful life of seven years.

Trade Name

We valued the trade names acquired using a relief from royalty method. The significant assumptions used in relief from royalty method include future expected cash flows from the trade name, the royalty rate and the discount rate. We are amortizing the trade names, valued at $0.5 million, on an attribution basis derived from the discounted cash flows of the model over an estimated useful life of five years.

Purchases of Patents and Patent Licenses

From time to time, we enter into agreements to purchase patents or patent licenses. The carrying value, net of amortization, of our purchased patents and patent licenses was $2.5 million and $2.9 million as of June 30, 2021 and December 31, 2020, respectively. As of June 30, 2021 and December 31, 2020, $0.7 million of patent costs were included in other current assets and $1.8 million and $2.2 million of patent costs were included in other assets, respectively. We have $7.0 million of historical cost in purchased patents and patent licenses as of June 30, 2021. We are amortizing the patent costs over the estimated useful lives of the patents, which range from three years to eighteen years. Patent cost amortization of $0.1 million and $0.2 million was included in cost of SaaS and license revenue in our condensed consolidated statements of operations for the three and six months ended June 30, 2021 and 2020, respectively. Patent cost amortization of $0.1 million was included in amortization and depreciation in our condensed consolidated statements of operations for each of the three and six months ended June 30, 2021 and 2020.

Loan to a Distribution Partner

In September 2016, we entered into dealer and loan agreements with a distribution partner. The dealer agreement enables the distribution partner to resell our SaaS services and hardware to their subscribers. Under the loan agreements, we agreed to loan the distribution partner up to $4.0 million, collateralized by all assets owned by the distribution partner. The advance period for the loan was amended in August 2017 to begin each year on September 1 and end each year on December 31. Interest on the outstanding principal accrued at a rate per annum equal to the greater of 6.0% or LIBOR, plus 4.0%, as determined on the first date of each annual advance period. The repayment of principal and accrued interest was due in three installments beginning in July and ending in August following the advance period. The maturity date of the loan was August 31, 2019; however, the borrower had the option to extend the term of the loan for two successive terms of one year each.

In May 2018, the loan agreement with our distribution partner was amended to convert the entire $4.0 million note receivable outstanding into a $4.0 million term loan. The term loan had a maturity date of July 31, 2022 and required annual principal repayments of $1.0 million on July 31 of each year, commencing on July 31, 2019. The term loan also required monthly interest payments, with interest accruing on the outstanding principal balance at a rate per annum equal to 6.0% through June 30, 2018 and a rate per annum equal to the LIBOR rate on the first of any interest period plus 7.0% beginning on July 1, 2018.

In April 2017, we entered into a subordinated credit agreement with an affiliated entity of the distribution partner and loaned the affiliated entity $3.0 million, with a maturity date of November 21, 2022. Interest on the outstanding principal balance accrued at a rate of 8.5% per annum and required monthly interest payments.

In June 2020, we amended the term loan with our distribution partner and also amended the subordinated credit agreement with the affiliated entity of the distribution partner. At the time of the amended term loan and subordinated credit agreement in June 2020, the outstanding balance of the term loan was $3.0 million and the outstanding balance of the subordinated credit agreement was $3.0 million. Under the amended terms, the distribution partner paid us $2.0 million in principal for the term loan on June 9, 2020 and the remaining $1.0 million was transferred to the amended subordinated credit agreement with the affiliated entity of the distribution partner.

The amended subordinated credit agreement with the affiliated entity of the distribution partner matures on September 9, 2025 and interest on the outstanding principal balance accrues at a rate of 9.0% per annum and is payable in kind. As of June 30, 2021 and December 31, 2020, $4.4 million and $4.2 million of the notes receivable balance related to the subordinated credit agreement was included in other assets in our condensed consolidated balance sheets, respectively.

For the three and six months ended June 30, 2021, we recognized $0.9 million and $1.6 million of revenue from the distribution partners associated with these loans, respectively, as compared to $0.9 million and $1.3 million for the same periods in the prior year.

Loans to Service Provider Partners

In July 2020, we entered into a loan agreement with a service provider partner, under which we agreed to loan the service provider partner up to $2.5 million, collateralized by the assets of the service provider partner. Interest on the outstanding principal accrues at a rate per annum equal to 9.0% and monthly interest and principal payments began in April 2021. The maturity date of the loan is July 24, 2025. As of each of June 30, 2021 and December 31, 2020, $1.2 million of principal was outstanding from the service provider partner under the loan agreement.

For the three and six months ended June 30, 2021 and 2020, we recognized less than $0.1 million and $0.1 million of revenue from the service provider partner associated with this loan, respectively.

Investment in a Hardware Supplier

In October 2018, we entered into a subordinate convertible promissory note with one of our hardware suppliers. In July 2019, we converted the outstanding notes receivable balance of $5.6 million into 9,520,832 shares of Series B preferred stock in the hardware supplier. We concluded that the $5.6 million equity investment, which is included in the Alarm.com segment, does not meet the criteria for consolidation and will be accounted for using the measurement alternative. Under the alternative, we measure investments without readily determinable fair values at cost, less impairment, adjusted for observable price changes from orderly transactions for identical or similar investments. As of June 30, 2021 and December 31, 2020, our investment in the hardware supplier was $5.6 million.

Investment in a Technology Partner

In December 2016, we paid $0.3 million for a convertible promissory note with a technology partner. In April 2018, the $0.3 million convertible promissory note converted into 135,135 shares of Series A-1 Preferred Stock. At the time of conversion, we determined there was no value related to the Series A-1 Preferred Stock. Based on observable price changes from orderly transactions for similar investments, we increased the amount of our investment by $0.7 million and recorded a gain within other income, net, in our consolidated statements of operations during the year ended December 31, 2020.

In February 2021, we paid $5.0 million in cash to purchase 1,000,000 shares of Series B-2 Preferred Stock from the same technology partner as part of a financing round that included other investors. The $5.0 million equity investment, which is included in the Alarm.com segment, does not meet the criteria for consolidation and is accounted for using the measurement alternative. Under the alternative, we measure investments without readily determinable fair values at cost, less impairment, adjusted for observable price changes from orderly transactions for identical or similar investments.

As of June 30, 2021 and December 31, 2020, our investment in the technology partner was $5.7 million and $0.7 million, respectively.

Allowance for Credit Losses - Notes Receivable

We identified the following two portfolio segments for our notes receivable: (i) loan receivables and (ii) hardware financing receivables. There were no changes to our portfolio segments for our notes receivable during the three and six months ended June 30, 2021, and no changes to our policies or practices involving the issuance of notes receivable, customer acquisitions or any other factors that influenced our estimate of expected credit losses for notes receivable.

We do not accrue interest on notes receivable that are considered impaired or are 90 days or greater past due based on their contractual payment terms. Notes receivable that are 90 days or greater past due are placed on nonaccrual status. Notes receivable may be placed on nonaccrual status earlier if, in management’s opinion, a timely collection of the full principal and interest becomes uncertain. After a note receivable has been placed on nonaccrual status, interest will be recognized when cash is received. A note receivable may be returned to accrual status after all of the customer’s delinquent balances of principal and interest have been settled, and collection of all remaining contractual amounts due is reasonably assured. We have elected not to measure an allowance for credit losses for accrued interest receivables. We write-off any accrued interest on notes receivable that are considered impaired or are 90 days or greater past due based on their contractual payment terms by reversing interest income. The accrued interest receivable as of each of June 30, 2021 and December 31, 2020 was less than $0.1 million, and is reflected in other current assets within our condensed consolidated balance sheets and excluded from the amortized cost basis of the notes receivable. We did not write-off any accrued interest receivable during the three and six months ended June 30, 2021 and 2020.

There were no purchases or sales of financial assets during the three and six months ended June 30, 2021 and 2020. There were no significant changes in the amount of note receivable write-offs during the three and six months ended June 30, 2021, as compared to historical periods.

During the three and six months ended June 30, 2021 and 2020, there was no interest income recognized related to notes receivables that were in nonaccrual status.

As of June 30, 2021 and December 31, 2020, there were no notes receivables placed in nonaccrual status for which there was not a related allowance for credit losses. As of June 30, 2021 and December 31, 2020, there were no notes receivables that were 90 days or greater past due for which we continued to accrue interest income.

Prepaid Expenses

As of June 30, 2021 and December 31, 2020, $12.0 million and $8.4 million of prepaid expenses were included in other current assets, respectively, primarily related to software licenses and for long lead-time parts related to our inventory.

The money market accounts are included in our cash and cash equivalents in our condensed consolidated balance sheets. Our money market assets are valued using quoted prices in active markets. See Note 12 for the carrying amount and estimated fair value of our convertible senior notes as of June 30, 2021.

The contingent consideration liability consisted of the potential earn-out payment related to our acquisition of 85% of the issued and outstanding capital stock of OpenEye on October 21, 2019. The earn-out payment was contingent on the satisfaction of certain calendar 2020 revenue targets and had a maximum potential payment of up to $11.0 million. During parts of 2019 and 2020, we accounted for the contingent consideration using fair value and established a liability for the future earn-out payment based on an estimation of revenue attributable to perpetual licenses and subscription licenses over the 2020 calendar year. The contingent consideration liability was valued with significant unobservable inputs, including the revenue volatility and the discount rate. Selecting another revenue volatility or discount rate within an acceptable range would not have resulted in a significant change to the fair value of the contingent consideration liability. As of October 21, 2019, the fair value of the liability was $2.8 million. At each reporting date until December 31, 2020, we remeasured the liability, using the same valuation approach. Changes in the fair value resulting from information that existed subsequent to the acquisition date were recorded in general and administrative expense in our condensed consolidated statements of operations. As of December 31, 2020, the 2020 revenue targets were not met and the fair value of the contingent consideration related to the potential earn-out payment decreased to zero as compared to the initial liability recorded at the acquisition date, primarily due to OpenEye's 2020 actual revenue being less than the projected revenue.

We monitor the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. There were no transfers in or out of Level 3 during the three and six months ended June 30, 2021 and 2020. We also monitor the value of the investments for other-than-temporary impairment on a quarterly basis. No other-than-temporary impairments occurred during the three and six months ended June 30, 2021 and 2020.

Leases [Abstract]

Leases

Leases

We lease office space, data centers and office equipment under non-cancelable operating leases with various expiration dates through 2026. In August 2014, we signed a lease for office space in Tysons, Virginia, where we relocated our headquarters to in February 2016. We have subsequently entered into amendments to this lease from 2015 to 2020 to provide us with additional office space. The lease term ends in 2026, includes a five-year renewal option and a cumulative tenant improvement allowance of $11.8 million.

Debt, Commitments and Contingencies

Debt, Commitments and Contingencies

The debt, commitments and contingencies described below would require us, or our subsidiaries, to make payments to third parties under certain circumstances.

Convertible Senior Notes

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes due January 15, 2026 in a private placement to qualified institutional buyers, or the 2026 Notes. The terms of the 2026 Notes are governed by an Indenture, or the Indenture, by and between Alarm.com Holdings, Inc. and U.S. Bank National Association, as trustee. The 2026 Notes are senior unsecured obligations that do not bear regular interest and the principal amount of the 2026 Notes will not accrete. The 2026 Notes may bear special interest under specified circumstances related to our failure to comply with our reporting obligations under the Indenture. Special interest, if any, will be payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2021. We received proceeds from the issuance of the 2026 Notes of $484.3 million, net of $15.7 million of transaction fees and other debt issuance costs.

We may not redeem the 2026 Notes prior to January 20, 2024. We may redeem for cash, all or any portion of the 2026 Notes, at our option, on or after January 20, 2024, at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date, if the last reported sale price of our common stock has been at least 130% of the conversion price for the 2026 Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. No sinking fund is provided for the 2026 Notes.

The 2026 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding August 15, 2025, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the 2026 Notes on each applicable trading day; (2) during the five business day period immediately after any 10 consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of 2026 Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the 2026 Notes on each such trading day; (3) if we call any or all of the 2026 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the 2026 Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events as set forth in the Indenture.

On or after August 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date of the 2026 Notes, holders of the 2026 Notes may convert all or any portion of their 2026 Notes at any time, regardless of the foregoing conditions. Upon conversion, we may satisfy our conversion obligation by paying or delivering, as the

case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. It is our current intent to settle the principal amount of the 2026 Notes with cash. The initial conversion rate for the 2026 Notes is 6.7939 shares of our common stock per $1,000 principal amount of 2026 Notes, which is equivalent to an initial conversion price of $147.19 per share of our common stock, subject to adjustment under certain circumstances in accordance with the terms of the Indenture. In addition, following certain corporate events that occur prior to the maturity date of the 2026 Notes or if we deliver a notice of redemption in respect of the 2026 Notes, we will, under certain circumstances, increase the conversion rate of the 2026 Notes for a holder who elects to convert its 2026 Notes (or any portion thereof) in connection with such a corporate event or convert its 2026 Notes called (or deemed called) for redemption during the related redemption period (as defined in the Indenture), as the case may be.

If we undergo a fundamental change (as defined in the Indenture), subject to certain exceptions and except as described in the Indenture, holders may require us to repurchase for cash all or any portion of their 2026 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.

The Indenture includes customary covenants and sets forth certain events of default after which the 2026 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving us after which the 2026 Notes become automatically due and payable.

We used some of the proceeds to repay the $110.0 million outstanding principal balance under our credit facility and also used some of the proceeds to pay accrued interest, fees and expenses related to our credit facility (see the section titled "2017 Facility" below). We are using the remaining net proceeds from the issuance of the 2026 Notes for working capital and other general corporate purposes, which may include acquisitions or strategic investments in complementary businesses or technologies.

In accounting for the transaction, the 2026 Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2026 Notes. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the contractual term of the 2026 Notes at an effective interest rate of 4.0%.

In accounting for the debt issuance costs of $15.7 million related to the 2026 Notes, we allocated the total amount incurred to the liability and equity components of the 2026 Notes based on their relative values. Issuance costs attributable to the liability component were $13.3 million and will be amortized to interest expense using the effective interest method over the contractual term of the 2026 Notes. Issuance costs attributable to the equity component were netted with the equity component in additional paid-in capital.

As of June 30, 2021, the fair value of our 2026 Notes was $467.1 million. The fair value was determined based on the quoted price of the 2026 Notes in an inactive market on the last traded day of the quarter and has been classified as Level 2 in the fair value hierarchy. Based on the closing price of our common stock of $84.70 on the last trading day of the quarter, the if-converted value of the 2026 Notes did not exceed the principal amount of $500.0 million as of June 30, 2021.

The net carrying amount of the liability component of the 2026 Notes is as follows (in thousands):

	June 30, 2021		December 31, 2020
Principal	$	500,000	$	—
Unamortized debt discount	(70,794)		—
Unamortized debt issuance costs	(12,285)		—
Net carrying amount	$	416,921	$	—

The net carrying amount of the equity component of the 2026 Notes is as follows (in thousands):

	June 30, 2021		December 31, 2020
Debt discount for conversion option	$	77,199	$	—
Debt issuance costs	(2,424)		—
Net carrying amount	$	74,775	$	—

Interest expense related to the 2026 Notes is as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Amortization of debt discount	$	3,592	$	—	$	6,404	$	—
Amortization of debt issuance costs	557		—		989		—
Total interest expense	$	4,149	$	—	$	7,393	$	—

The difference between the book and tax treatment of the debt discount and debt issuance costs of the 2026 Notes resulted in a difference between the carrying amount and tax basis of the 2026 Notes. This taxable temporary difference resulted in the recognition of a $18.3 million net deferred tax liability which was recorded as an adjustment to additional paid-in capital during the three months ended March 31, 2021.

2017 Facility

On October 6, 2017, we entered into a $125.0 million senior secured revolving credit facility, or the 2017 Facility, with Silicon Valley Bank, or SVB, as administrative agent, PNC Bank, National Association, as documentation agent, and a syndicate of lenders. Upon entry into the 2017 Facility, we borrowed $72.0 million, which was used to repay the previously outstanding balance under our previous credit facility. The 2017 Facility was set to mature in October 2022 and included an option to further increase the borrowing capacity to $175.0 million with the consent of the lenders. Costs incurred in connection with the 2017 Facility were capitalized and were being amortized as interest expense over the term of the 2017 Facility. The 2017 Facility was secured by substantially all of our assets, including our intellectual property. On March 25, 2020, we borrowed $50.0 million under the 2017 Facility as a precautionary measure in order to provide financial flexibility in light of current uncertainty in the financial markets resulting from the COVID-19 pandemic. On January 20, 2021, we repaid the entire outstanding principal balance of $110.0 million of the 2017 Facility with proceeds from the 2026 Notes. The 2017 Facility was terminated on January 20, 2021 and we recognized an extinguishment loss of $0.2 million in other income / (expense), net in our condensed consolidated statements of operations during the six months ended June 30, 2021 for previously capitalized debt issuance costs related to the 2017 Facility that were unamortized at the time of the termination of the 2017 Facility.

The outstanding principal balance on the 2017 Facility accrued interest at a rate equal to, at our option, either (1) LIBOR, plus an applicable margin based on our consolidated leverage ratio, or (2) the highest of (a) the Wall Street Journal prime rate, (b) the Federal Funds rate plus 0.50%, or (c) LIBOR plus 1.00% plus an applicable margin based on our consolidated leverage ratio. During 2021 until the termination of the 2017 Facility on January 20, 2021, we elected for the outstanding principal balance to accrue interest at LIBOR plus 1.50%, LIBOR plus 1.75%, LIBOR plus 2.00%, and LIBOR plus 2.50% when our consolidated leverage ratio is less than 1.00:1.00, greater than or equal to 1.00:1.00 but less than 2.00:1.00, greater than or equal to 2.00:1.00 but less than 3.00:1.00 and greater than or equal to 3.00:1.00, respectively. The 2017 Facility also carried an unused line commitment fee of 0.20%. For the six months ended June 30, 2020, the effective interest rate on the 2017 Facility was 3.42%.

The carrying value of the 2017 Facility was zero and $110.0 million as of June 30, 2021 and December 31, 2020, respectively. The 2017 Facility included a variable interest rate that approximated market rates and, as such, we classified the liability as Level 2 within the fair value hierarchy and determined that the carrying amount of the 2017 Facility approximated its fair value as of December 31, 2020.

Commitments and Contingencies

Contingent Consideration

On October 21, 2019, we acquired 85% of the issued and outstanding capital stock of OpenEye. Certain stockholders of OpenEye had the right to receive an earn-out payment of up to an additional $11.0 million based upon satisfaction of certain calendar 2020 revenue targets. At October 21, 2019, the fair value of the contingent consideration liability was $2.8 million. At each reporting date until December 31, 2020, we remeasured the liability, using the same valuation approach. Changes in the fair value resulting from information that existed subsequent to the acquisition date were recorded in the condensed consolidated statements of operations. As of December 31, 2020, the 2020 revenue targets were not met and the fair value of the contingent consideration related to the potential earn-out payment decreased to zero as compared to the initial liability recorded at the acquisition date, primarily due to OpenEye's 2020 actual revenue being less than the projected revenue (see Note 9).

Indemnification Agreements

We have various agreements that may obligate us to indemnify the other party to the agreement with respect to certain matters. Generally, these indemnification provisions are included in contracts arising in the normal course of business. Although we cannot predict the maximum potential amount of future payments that may become due under these indemnification agreements, we do not believe any potential liability that might arise from such indemnity provisions is probable or material.

Legal Proceedings

On June 2, 2015, Vivint, Inc., or Vivint, filed a lawsuit against us in U.S. District Court, District of Utah, alleging that our technology directly and indirectly infringes six patents that Vivint purchased. Vivint is seeking permanent injunctions, enhanced damages and attorneys' fees. We answered the complaint on July 23, 2015. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. On August 19, 2016, the U.S. District Court, District of Utah stayed the litigation pending inter partes review by the U.S. Patent Trial and Appeal Board, or PTAB, of five of the patents in suit. In March 2017, the PTAB issued final written decisions relating to two patents finding all challenged claims unpatentable. In May 2017, the PTAB issued final written decisions relating to the remaining three patents that found certain claims unpatentable, while certain other claims were not found to be unpatentable. Vivint appealed the decisions to the U.S. Court of Appeals for the Federal Circuit, or the Federal Circuit, and we cross-appealed. In July 2018, the Federal Circuit issued orders affirming the PTAB’s March 2017 decisions that invalidated all challenged claims of two patents. The U.S. District Court, District of Utah lifted the stay on the litigation on June 26, 2017, with Vivint proceeding with its case on four of the six patents in its complaint. No trial date has been set. In September 2017, the U.S. Patent and Trademark Office, or PTO, ordered ex parte reexaminations of certain claims of two of the remaining patents in suit, at our request. On October 30, 2018 and November 5, 2018, the PTO issued final office actions in the pending reexaminations rejecting all claims being examined as unpatentable over the prior art. Nine claims asserted in the litigation were found unpatentable in the PTO rejections. Vivint appealed these rejections to the PTAB on March 29, 2019 and April 4, 2019. The PTAB issued decisions affirming the rejections on February 28, 2020 and May 4, 2020. Vivint appealed these decisions to the Federal Circuit on July 1, 2020 and April 26, 2021. On December 20, 2018, the Federal Circuit issued an order regarding the inter partes review of three of the remaining patents in suit that vacated, reversed and remanded the PTAB’s ruling with regard to the construction of a term (“communication device identification code”) as requested by Alarm.com and affirmed the PTAB’s May 2017 rulings invalidating certain of the Vivint patents in all other respects. On July 24, 2019, the PTAB issued further decisions with respect to two of the remaining patents in suit, finding additional claims unpatentable in view of the Federal Circuit’s December 20, 2018 decision. One of the claims asserted in the litigation was found unpatentable in the July 14, 2019 decisions. Vivint appealed the July 24, 2019 decisions to the Federal Circuit on September 25, 2019. On April 13, 2021, the Federal Circuit affirmed the PTAB decisions. On February 12, 2021, we filed an action in U.S. District Court, Eastern District of Virginia challenging the refusal by the PTO to proceed with additional reexaminations of the remaining patent claims asserted in the lawsuit. The U.S. District Court, Eastern District of Virginia granted the PTO’s motion to dismiss the case for lack of jurisdiction on June 22, 2021. We appealed the dismissal to the Federal Circuit on June 24, 2021.

Should Vivint prevail in proving Alarm.com infringes one or more of its patent claims, we could be required to pay damages of Vivint’s lost profits and/or a reasonable royalty for sales of our solution. Since all remaining patent claims in the litigation have expired, Vivint shall not be entitled to injunctive relief as a remedy in this matter. While we believe we have valid defenses to Vivint’s claims, any of these outcomes could result in a material adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

On October 22, 2019, EcoFactor, Inc., or EcoFactor, filed a complaint with the U.S. International Trade Commission, or ITC, naming Alarm.com Incorporated and Alarm.com Holdings, Inc., among others, as proposed respondents. The complaint alleges that Alarm.com’s smart thermostats infringe three U.S. patents owned by EcoFactor. EcoFactor is seeking a permanent limited exclusion order and permanent cease and desist order. On November 22, 2019, the ITC instituted an investigation into EcoFactor’s allegations naming Alarm.com Incorporated, Alarm.com Holdings, Inc. and others as respondents. We answered the complaint on December 19, 2019. Among other things, we asserted defenses based on non-infringement and invalidity of the

patents in question. An evidentiary hearing was held in November 2020. On April 20, 2021, the administrative law judge presiding over the investigation issued a final initial determination finding in favor of Alarm.com. On July 20, 2021, the ITC commissioners issued a decision affirming the ruling in favor of Alarm.com and terminated the investigation.

On November 11, 2019, EcoFactor filed a lawsuit against us in U.S. District Court, District of Massachusetts, alleging infringement of the same three patents asserted against us in the ITC. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. On December 26, 2019, the court issued an order staying the lawsuit pending the conclusion of the related ITC investigation.

On May 26, 2020, EcoFactor filed a second lawsuit against us in U.S. District Court, District of Massachusetts, alleging Alarm.com’s products and services infringe four additional U.S. patents owned by EcoFactor. EcoFactor is seeking permanent injunctions, enhanced damages and attorneys' fees. On March 9, 2021, the PTO ordered ex parte reexamination of one of the patents asserted in the lawsuit, at Alarm.com’s request. On May 10, 2021, the PTAB instituted inter partes review of the same patent and subsequently stayed the ex parte reexamination pending the conclusion of its review. On May 13, 2021, the court issued an order staying the lawsuit until September 3, 2021 in light of the related ITC investigation.

Should EcoFactor prevail in its district court lawsuits we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to EcoFactor’s claims, the outcome of these legal claims cannot be predicted with certainty and any of these outcomes could result in an adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

On July 22, 2021, Causam Enterprises, Inc., or Causam, filed a lawsuit against us in U.S. District Court, Western District of Texas, alleging that Alarm.com’s smart thermostats infringe four U.S. patents owned by Causam. Causam is seeking preliminary and permanent injunctions, enhanced damages and attorneys’ fees. Our response is due on September 13, 2021.

On July 28, 2021, Causam filed a complaint with the ITC naming Alarm.com Incorporated, Alarm.com Holdings, Inc., and EnergyHub, Inc., among others, as proposed respondents. The complaint alleges infringement of the same four patents Causam asserted in district court. Causam is seeking a permanent limited exclusion order and permanent cease and desist order. The ITC has not yet instituted an investigation into the allegations.

Should Causam prevail in an ITC investigation, Alarm.com thermostats manufactured abroad could be excluded from importation into the United States. Should Causam prevail in its district court lawsuit we could be required to pay damages and/or a reasonable royalty for sales of our solution, we could be enjoined from making, using and selling our solution if a license or other right to continue selling such elements is not made available to us, and we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. While we believe we have valid defenses to Causam’s claims, the outcome of these legal claims cannot be predicted with certainty, and any of these outcomes could result in an adverse effect on our business. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

In addition to the matters described above, we may be required to provide indemnification to certain of our service provider partners for certain claims regarding our solutions. For example, we are incurring costs associated with the indemnification of our service provider ADT, LLC in ongoing patent infringement suits.

On July 13, 2016, Applied Capital, Inc., or Applied Capital, filed a lawsuit against ADT, LLC, the ADT Corporation, and Icontrol Networks, Inc. in U.S. District Court, the District of New Mexico.  Applied Capital, Inc v. The ADT Corporation et al., D. New Mexico Case No. 1-16-cv-00815. Icontrol was dismissed without prejudice on May 22, 2017.  Applied Capital alleges that ADT’s sales of ADT Pulse directly and indirectly infringes U.S. Patent Nos. 8,378,817 and 9,728,082, which were allegedly purchased by Applied Capital. Applied Capital is seeking damages and attorneys’ fees.  ADT answered Applied Capital’s amended complaint on July 16, 2018. Among other things, ADT has asserted defenses based on non-infringement and invalidity of the patents-in-suit. On April 5, 2019, Applied Capital filed a lawsuit for breach of contract against Rodney Fox, the inventor of the patents-in-suit, in the Second Judicial District Court, County of Bernalillo in New Mexico State Court (No. D-202-CV-2019-02841). Mr. Fox counterclaimed, alleging that he is the rightful owner of the patents-in-suit. Based on the dispute of ownership, on October 15, 2019, ADT filed a motion to stay in this matter pending its resolution. Applied Capital and Mr. Fox reached settlement and stipulated to dismissal of the New Mexico State Court action on October 31, 2019. Applied Capital filed its Second Amended Complaint on January 27, 2020 and ADT answered, adding a claim of inequitable conduct, on February 10, 2020. The court issued its claim construction order on August 12, 2019, fact discovery closed on November 12, 2019, expert discovery closed on March 9, 2020, and summary judgment and Daubert motions briefing closed on June 3, 2020. The parties reached settlement and the court dismissed the case on May 27, 2021.

On February 25, 2021, Vivint filed a lawsuit against ADT LLC a/k/a ADT LLC of Delaware d/b/a ADT Security Services in U.S. District Court, District of Utah, alleging that ADT Pulse, Control, and Blue each infringe one or more of six patents owned by Vivint. Vivint is seeking damages and attorneys’ fees. Vivint filed an amended complaint on March 24, 2021. ADT answered the amended complaint on April 30, 2021 and asserted defenses based on non-infringement and invalidity of all the patents in question, and inequitable conduct as to one of the patents. On June 25, 2021, ADT filed a motion for judgment on the pleadings seeking judgment in its favor as to five of the six asserted patents on the grounds that the claimed inventions are directed to ineligible subject matter.

Should Vivint prevail on the claims that one or more elements of ADT’s products infringe, we could be required to indemnify ADT for damages in the form of a reasonable royalty or ADT could be enjoined from making, using and selling our solution if a license or other right to continue selling our technology is not made available or we are unable to design around such patents, and required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us. The outcome of these legal claims cannot be predicted with certainty. We believe there are valid defenses to the claims made by Vivint. Based on currently available information, we have determined a loss is not probable or reasonably estimable at this time.

We may also be a party to litigation and subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business.

Other than the preceding matters, we are not a party to any lawsuit or proceeding that, in the opinion of management, is reasonably possible or probable of having a material adverse effect on our financial position, results of operations or cash flows. We reserve for contingent liabilities based on ASC 450, "Contingencies," when it is determined that a liability, inclusive of defense costs, is probable and reasonably estimable. Litigation is subject to many factors that are difficult to predict, so there can be no assurance that, in the event of a material unfavorable result in one or more claims, we will not incur material costs.

Restricted stock units	149,291	12,965	123,091	105,015

Our redeemable noncontrolling interest relates to our 85% equity ownership interest in OpenEye. The OpenEye stockholder agreement contains a put option that gives the minority OpenEye stockholders the right to sell their OpenEye shares to us based on the fair value of the shares. The OpenEye stockholder agreement also contains a call option that gives us the right to purchase the remaining OpenEye shares from the minority OpenEye stockholders based on the fair value of the shares. The put and call options can each be exercised beginning in the first quarter of 2023. This redeemable noncontrolling interest is considered temporary equity and we report it between liabilities and stockholders’ equity in the condensed consolidated balance sheets. The amount of the net income or loss attributable to redeemable noncontrolling interests is recorded in the condensed consolidated statements of operations.

Since we expect to settle the principal amount on our outstanding 2026 Notes in cash and any excess in cash or shares of our common stock, we use the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The conversion spread has a dilutive impact on diluted net income per share of common stock when the average market price of our common stock for a given period exceeds the conversion price of $147.19 per share for the 2026 Notes. Based on the initial conversion price and the average market price of our common stock for the three and six months ended June 30, 2021, there was no dilutive effect of the 2026 Notes on our earnings per share during the three and six months ended June 30, 2021.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

For purposes of interim reporting, our annual effective income tax rate is estimated in accordance with ASC 740-270, "Interim Reporting." This rate is applied to the pre-tax book income of the entities expected to be benefited during the year. Discrete items that impact the tax provision are recorded in the period incurred.

For the three and six months ended June 30, 2021, we recorded a benefit from income taxes of $1.7 million and $4.7 million, respectively, resulting in an effective income tax rate of (13.6)% and (19.1)% for those periods. For the three and six months ended June 30, 2020, we recorded a benefit from income taxes of $2.3 million and $1.1 million, respectively, resulting in an effective income tax rate of (15.9)% and (4.5)% for those periods. Our effective tax rates were below the statutory rate primarily due to research and development tax credits claimed, tax windfall benefits from employee stock-based payment transactions and foreign derived intangible income deductions, partially offset by the impact of state taxes, foreign withholding taxes and other nondeductible expenses.

We recognize a valuation allowance if, based on the weight of available evidence, both positive and negative, it is more likely than not that some portion, or all, of net deferred tax assets will not be realized. Due to the uncertainty of realization of certain deferred tax assets acquired in 2017 related to our Canadian net operating losses and research and development tax credits, we established a valuation allowance of $0.3 million during the second quarter of 2019, which remained at $0.3 million as of June 30, 2021 and December 31, 2020. During 2020, we established a valuation allowance of $1.3 million for state research and development tax credit carryforwards, which remained at $1.3 million as of June 30, 2021 and December 31, 2020.

We apply guidance for uncertainty in income taxes that requires the application of a more likely than not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, this guidance permits us to recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is more likely than not to be realized upon settlement. We recorded an increase to the unrecognized tax benefits of $1.5 million primarily for research and development tax credits claimed during the six months ended June 30, 2021. We recorded unrecognized tax benefits of $1.9 million for research and development tax credits claimed during the six months ended June 30, 2020.

As of June 30, 2021 and December 31, 2020, we accrued $0.1 million of total interest expense related to unrecognized tax benefits. We recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include our accounts and those of our majority-owned and controlled subsidiaries after elimination of intercompany accounts and transactions.

These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission, or SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual financial statements. They should be read together with our audited consolidated financial statements and related notes thereto for the year ended December 31, 2020 included in our Annual Report on Form 10-K filed with the SEC on February 25, 2021, or the Annual Report. The condensed consolidated balance sheet as of December 31, 2020 was derived from our audited financial statements, but does not include all disclosures required by GAAP for annual financial statements.

In the opinion of management, these condensed consolidated financial statements include all normal recurring adjustments necessary for a fair statement of the results of operations, financial position and cash flows for the periods presented.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. As of the date of issuance of these financial statements, we are not aware of any specific event or circumstance that would require us to update our estimates, assumptions and judgments or revise the carrying value of our assets or liabilities. However, our estimates, judgments and assumptions are continually evaluated based on available information and experience and may change as new events occur and additional information is obtained. Because of the use of estimates inherent in the financial reporting process and in light of the continuing uncertainty arising from the COVID-19 pandemic, actual results could differ from those estimates and any such differences may be material. Estimates are used when accounting for revenue recognition, allowances for credit losses, allowance for hardware returns, estimates of obsolete inventory, long-term incentive compensation, the lease term and incremental borrowing rates for leases, stock-based compensation, income taxes, legal reserves, fair value of the debt component of convertible notes, contingent consideration and goodwill and intangible assets.

Convertible Senior Notes

Convertible Senior Notes

On January 20, 2021, we issued $500.0 million aggregate principal amount of 0% convertible senior notes in a private placement to qualified institutional buyers due January 15, 2026. In accounting for the issuance of our convertible senior notes, we separate the notes into liability and equity components. The carrying amount of the liability component is calculated by measuring the fair value of a similar liability that does not have an associated convertible feature, using a discounted cash flow model with a risk adjusted yield. The carrying amount of the equity component representing the conversion option is determined by deducting the fair value of the liability component from the par value of the notes as a whole. This difference represents a debt discount that is amortized to interest expense using the effective interest method over the term of the notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the transaction costs related to the issuance of the notes, we allocate the total amount incurred to the liability and equity components using the same proportions as the proceeds from the notes. Transaction costs attributable to the liability component are netted with the liability component and amortized to interest expense using the effective interest method over the term of the notes. Transaction costs attributable to the equity component are netted with the equity component of the notes in additional paid-in capital in the condensed consolidated balance sheets. See Note 12 for the carrying amount and estimated fair value of our convertible senior notes as of June 30, 2021.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Adopted

On December 18, 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes," which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The update also simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance to improve consistent application. The amendment in this update was effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. On January 1, 2021, we adopted Topic 740. This pronouncement did not have a material impact on our condensed consolidated financial statements or disclosures.

Not Yet Adopted

On March 12, 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued such as the Eurodollar Base Rate, or LIBOR. The update allows entities to elect not to apply certain modification accounting requirements to contracts affected by the discontinuation of a reference rate if certain criteria are met. The amendment was effective beginning March 12, 2020 and will continue to be effective through December 31, 2022. Due to the termination of our credit facility on January 20, 2021 (see Note 12), this pronouncement is not expected to have an impact on our condensed consolidated financial statements or disclosures.

On August 5, 2020, the FASB issued ASU 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity," which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The new guidance eliminates two of the three models in Subtopic 470-20 that require separating embedded conversion features from convertible instruments. The guidance also addresses how convertible instruments are accounted for in the diluted earnings per share calculation. The amendment in this update is effective for fiscal years beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The guidance allows for either full retrospective adoption or modified retrospective adoption. We are currently assessing the impact this pronouncement may have on our consolidated financial statements when we adopt the pronouncement on January 1, 2022.

Revenue Recognition

Revenue Recognition

We derive our revenue from three primary sources: the sale of cloud-based SaaS services on our integrated Alarm.com platform, the sale of licenses and services on our non-hosted software platform, or Software platform, and the sale of hardware products. We sell our platform and hardware solutions to service provider partners that resell our solutions and hardware to residential and commercial property owners, who are the service provider partners’ customers. Our subscribers consist of all of the properties maintained by those residential and commercial property owners to which we are delivering at least one of our solutions. We also sell our hardware to distributors who resell the hardware to service provider partners. We enter into contracts with our service provider partners that establish pricing for access to our platform solutions and for the sale of hardware. These service provider contracts typically have an initial term of one year, with subsequent renewal terms of one year. Our service provider partners typically enter into contracts with our subscribers, which our service provider partners have indicated range from three to five years in length.

When determining the amount of consideration we expect to be entitled to for the sale of our hardware, we estimate the variable consideration associated with customer returns. We record a reserve against revenue for hardware returns based on historical returns. For the twelve months ended June 30, 2021 and 2020, our reserve against revenue for hardware returns was 1%. We evaluate our hardware reserve on a quarterly basis or if there is an indication of significant changes in return experience. Historically, our returns of hardware have not significantly differed from our estimated reserve. Additionally, we provide warranties related to the intended functionality of the products and services provided and those warranties typically allow for the return of hardware up to one year past the date of sale. We determined that these warranties are not separate performance obligations as they cannot be purchased separately and do not provide a service in addition to an assurance the hardware will function as expected.

Our hardware and other revenue also includes our revenue from the sale of perpetual licenses that provide our customers in the commercial market the right to use our OpenEye video surveillance software for an indefinite period of time in exchange for a one-time license fee, which is generally paid at contract inception. Our hardware and other revenue also includes our revenue from Shooter Detection Systems related to the sale of licenses that provide our customers the right to use our indoor gunshot detection solution in exchange for license fees, which are generally paid at contract inception. Our perpetual licenses and licenses to our indoor gunshot detection solution provide a right to use intellectual property that is functional in nature and has significant stand-alone functionality. Accordingly, for licenses of functional intellectual property, revenue is recognized at the point-in-time when control has been transferred to the customer, which occurs once the software has been made available to the customer.

Hardware and other revenue may also include activation fees charged to some of our service provider partners for activation of a new subscriber account on our platforms, as well as fees paid by service provider partners for our marketing services. Our service provider partners use services on our platforms, such as support tools and applications, to assist in the installation of our solutions in subscriber properties. This installation marks the beginning of the service period on our platforms and, on occasion, we earn activation revenue for fees charged for this service. The activation fee is non-refundable, separately negotiated and specified in our contractual arrangements with our service provider partners and is charged to the service provider partner for each subscriber activated on our platforms. The decision whether to charge an activation fee is based in part on the expected number of subscribers to be added by our service provider partners and as a result, many of our largest service provider partners do not pay an activation fee. Activation fees are not offered on a stand-alone basis separate from our SaaS offering and are billed and received at the beginning of the arrangement. We record activation fees initially as deferred revenue and we recognize these fees ratably over the expected term of the subscribers’ account which we estimate is ten years based on our annual attrition rate. The portion of these activation fees included in current and long-term deferred revenue as of our balance sheet date represents the amounts that will be recognized ratably as revenue over the following twelve months, or longer as appropriate, until the ten-year expected term is complete. The balance of deferred revenue for activation fees was $6.5 million and $7.0 million as of June 30, 2021 and December 31, 2020, respectively, which combines current and long-term balances.

SaaS and license revenue associated with our contracts is invoiced and revenue is recognized at an amount that corresponds directly with the value of the performance completed to date. Additionally, the consideration received from hardware sales corresponds directly with the stand-alone selling price of the hardware. As a result, we have elected to use the practical expedient related to the amount of transaction price allocated to the unsatisfied performance obligations and therefore, we have not disclosed the total remaining revenue expected to be recognized on all contracts or the expected period over which the remaining revenue would be recognized.

Contract Assets and Contract Liabilities

Contract Assets

At contract inception, we assess the goods and services promised in our contracts with customers and identify a performance obligation for each distinct promise to transfer a good or service, or bundle of goods or services. To identify the performance obligations, we consider all of the goods or services promised in the contract, whether explicitly stated or implied

based on customary business practices. We record a contract asset when we satisfy a performance obligation by transferring a promised good or service. Contract assets can be conditional or unconditional depending on whether another performance obligation must be satisfied before payment can be received. We receive payments from our service provider partners based on the billing schedule established in our contracts. All of the accounts receivable presented in the condensed consolidated balance sheets represent unconditional rights to consideration. We do not have any assets from contracts containing conditional rights and we do not have any assets from satisfied performance obligations that have not been invoiced.

We recognize an asset related to the costs incurred to obtain a contract only if we expect to recover those costs and we would not have incurred those costs if the contract had not been obtained. We recognize an asset from the costs incurred to fulfill a contract if the costs (i) are specifically identifiable to a contract, (ii) enhance resources that will be used in satisfying performance obligations in future and (iii) are expected to be recovered. Our contract assets consist of capitalized commission costs and upfront payments made to a customer. Based on the policy above, we capitalize a portion of our commission costs as an incremental cost of obtaining a contract. When calculating the incremental cost of obtaining a contract, we exclude any commission costs related to metrics that could be satisfied without obtaining a contract, including training-related metrics. We amortize our commission costs over a period of three years, which is consistent with the period over which the products and services related to the commission are transferred to the customer. The three-year period was determined based on our review of historical enhancements and upgrades to our products and services. We applied the portfolio approach to account for the amortization of contract costs for those contracts that have similar characteristics. Upfront payments made to a customer are capitalized and amortized over the expected period of benefit and are recorded as a reduction to revenue.

Contract Liabilities

Contract liabilities include payments received in advance of performance under the contract and are realized with the associated revenue recognized under the contract. All of the deferred revenue presented in the condensed consolidated balance sheets represents contract liabilities resulting from advance cash receipts from customers or amounts billed in advance to customers from the sale of services. Changes in deferred revenue are due to our performance under the contract as well as to cash received from new contracts for which services have not been provided.

Allowance for Credit Losses - Accounts Receivable

Allowance for Credit Losses - Accounts Receivable

The allowance for credit losses is a valuation account that is deducted from the accounts receivable and notes receivable amortized cost basis (see Note 8) to present the net amount expected to be collected. We estimate the allowance balance by applying the loss-rate method using relevant available information from internal and external sources, including historical write-off activity, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for changes in economic conditions, such as changes in unemployment rates. We use projected economic conditions over a period no more than twelve months based on data from external sources. For periods beyond the twelve-month reasonable and supportable forecast period, we revert to historical loss information immediately.

The allowance for credit losses is measured on a pooled basis when similar risk characteristics exist. When assessing whether to measure certain financial assets on a pooled basis, we considered various risk characteristics, including the financial asset type, size and the historical or expected credit loss pattern. We identified the following two portfolio segments for our accounts receivable: (i) outstanding accounts receivable balances within Alarm.com and certain subsidiaries and (ii) outstanding accounts receivable balances within all other subsidiaries. There were no changes to our portfolio segments for our accounts receivable during the three and six months ended June 30, 2021, and no changes to our policies or practices that influenced our estimate of expected credit losses for accounts receivable. There were no significant changes in the amount of accounts receivable write-offs during the three and six months ended June 30, 2021, as compared to historical periods other than a partial write-off of $0.7 million related to one of our distribution partners' outstanding balance during the six months ended June 30, 2021, upon the distributor being acquired by a third party.

Expected credit losses are estimated over the contractual term of the financial assets and we adjust the term for expected prepayments when appropriate. For the three and six months ended June 30, 2021, we recorded credit loss expense for accounts receivable and notes receivable of $0.1 million and less than $0.1 million, respectively, in general and administrative expense in our condensed consolidated statements of operations. For the three months ended June 30, 2020, we recorded a reduction of credit loss expense of $0.9 million and for the six months ended June 30, 2020, we recorded credit loss expense of $0.5 million in general and administrative expense in our condensed consolidated statements of operations. The contractual term excludes expected extensions, renewals and modifications because extension and renewal options are unconditionally cancelable by us. Write-offs of the amortized cost basis are recorded to the allowance for credit losses. Any subsequent recoveries of previously written off balances are recorded as a reduction to credit loss expense.

Income Taxes

We recognize a valuation allowance if, based on the weight of available evidence, both positive and negative, it is more likely than not that some portion, or all, of net deferred tax assets will not be realized. Due to the uncertainty of realization of certain deferred tax assets acquired in 2017 related to our Canadian net operating losses and research and development tax credits, we established a valuation allowance of $0.3 million during the second quarter of 2019, which remained at $0.3 million as of June 30, 2021 and December 31, 2020. During 2020, we established a valuation allowance of $1.3 million for state research and development tax credit carryforwards, which remained at $1.3 million as of June 30, 2021 and December 31, 2020.We apply guidance for uncertainty in income taxes that requires the application of a more likely than not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, this guidance permits us to recognize a tax benefit measured at the largest amount of the tax benefit that, in our judgment, is more likely than not to be realized upon settlement.
