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, 2023 included in our Annual Report on Form 10-K filed with the SEC on February 22, 2024, or the Annual Report. The condensed consolidated balance sheet as of December 31, 2023 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 global economy, credit markets and financial markets have and may continue to experience significant volatility as a result of significant worldwide events, including public health crises, and geopolitical upheaval, such as Russia’s incursion into Ukraine and the conflict between Israel and regional adversaries, disruptions to global supply chains, rising interest rates, risk of recession and inflation (collectively, the Macroeconomic Conditions). These Macroeconomic Conditions have and may continue to create supply chain disruptions, inventory disruptions, and fluctuations in economic growth, including fluctuations in employment rates, inflation, energy prices and consumer sentiment. It remains difficult to assess or predict the ultimate duration and economic impact of the Macroeconomic Conditions. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that can be expected for our entire fiscal year ending December 31, 2024, which is increasingly true in periods of extreme uncertainty, such as the uncertainty caused by the Macroeconomic Conditions. Prolonged uncertainties 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 Macroeconomic Conditions, 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, goodwill, intangible assets and other long-lived assets. Significant Accounting Policies Other than those disclosed herein, there have been no other material changes to our significant accounting policies during the three and nine months ended September 30, 2024 from those disclosed in our Annual Report. Capped Call Transactions On May 31, 2024, we issued $500.0 million aggregate principal amount of 2.25% convertible senior notes due June 1, 2029 in a private placement to qualified institutional buyers, or the 2029 Notes. In connection with the offering of the 2029 Notes, we entered into privately negotiated capped call transactions with one of the initial purchasers and certain other financial institutions, at a cost of $63.1 million. The capped call transactions cover, subject to customary adjustments substantially similar to those applicable to the 2029 Notes, the number of shares of our common stock initially underlying the 2029 Notes. As the capped call options are both legally detachable and separately exercisable from the 2029 Notes, we account for the capped call options separately from the 2029 Notes. The capped call options are indexed to our own common stock and classified in stockholders’ equity. As such, the premiums paid for the capped call options were included as a net reduction to additional paid-in capital in the condensed consolidated balance sheets. The capped call transactions will not be remeasured as long as they continue to meet the conditions for equity classification. We elected to integrate the capped call options with the 2029 Notes for federal income tax purposes pursuant to applicable U.S. Treasury Regulations. Accordingly, the $63.1 million cost of the purchased capped calls will be deductible for income tax purposes. The original issue discount is accreted over the term of the 2029 Notes. Recent Accounting Pronouncements Adopted During the three and nine months ended September 30, 2024, we did not adopt any new accounting pronouncements. Not Yet Adopted On November 27, 2023, the Financial Accounting Standards Board, or FASB, issued ASU 2023-07, "Segment Reporting (Topic 280),” which revises the disclosure requirements about a public entity’s reportable segments and a reportable segment’s expenses. This amendment requires a public entity to (i) disclose significant segment expense that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, (ii) disclose an amount for other segment items by reportable segment and a description of its composition and (iii) provide annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 in interim periods. The amendment is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. This amendment is required to be applied retrospectively to all prior periods presented. We expect this amendment to increase the amount of disclosures we provide within Note 18 related to segment expenses in the annual reporting period ending December 31, 2024 and interim reporting periods thereafter. On December 14, 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740)," which requires additional annual disclosures regarding specific categories in the income tax rate reconciliation as well additional information for reconciling items that meet a quantitative threshold. This amendment also requires annual disclosures regarding the amount of income taxes paid, including income taxes paid disaggregated by (i) federal, state and foreign taxes as well as (ii) individual jurisdictions in which income taxes paid is equal to or greater than five percent of total income taxes paid. Additionally, this amendment requires annual disclosures for income from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign as well as income tax expense (or benefit) disaggregated between federal, state and foreign. The amendment is effective for annual periods beginning after December 15, 2024, and early adoption is permitted. This amendment should be applied on a prospective basis, but retrospective application is permitted. We are currently assessing the impact this pronouncement will have on our consolidated financial statement disclosures. On November 5, 2024, the FASB issued ASU 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)," which requires more detailed information about the types of expenses included in certain expense captions presented on the consolidated statements of operations, including purchases of inventory, employee compensation, depreciation, amortization and depletion. Additionally, this amendment requires the disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and the disclosure of the total amount of selling expenses and, on an annual basis, an entity's definition of selling expenses. The amendment is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. This amendment should be applied either on a prospective basis or a retrospective basis to any or all prior periods presented. We are currently assessing the impact this pronouncement will have on our consolidated financial statement disclosures.

Accounts Receivable, Net	Accounts Receivable, Net The components of accounts receivable, net are as follows (in thousands): September 30, December 31, Accounts receivable $ 127,371 $ 136,769 Allowance for credit losses (3,847) (3,864) Allowance for product returns (2,547) (2,279) Accounts receivable, net $ 120,977 $ 130,626 For the three and nine months ended September 30, 2024, we recorded a provision for credit losses of $0.1 million and $0.5 million, respectively, as compared to $0.8 million and $1.4 million for the same periods in the prior year. For the three and nine months ended September 30, 2024, we recorded a reserve for product returns of $0.7 million and $2.7 million in our hardware and other revenue, respectively, as compared to $0.5 million and $3.0 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 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. 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 months ended September 30, 2024, we recorded a reduction to credit loss expense for accounts receivable and notes receivable of $0.1 million and for the nine months ended September 30, 2024, we recorded credit loss expense for accounts receivable and notes receivable of $4.1 million, in general and administrative expense in our condensed consolidated statements of operations. For the three and nine months ended September 30, 2023, we recorded credit loss expense for accounts receivable and notes receivable of $0.6 million and $1.1 million, respectively, 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. Allowance for Credit Losses - Accounts Receivable 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 nine months ended September 30, 2024, and no changes to our policies or practices that influenced our estimate of expected credit losses for accounts receivable. Additionally, there were no significant changes in the amount of accounts receivable write-offs during the three and nine months ended September 30, 2024, as compared to historical periods.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Acquisitions	Acquisitions Asset Acquisition On April 21, 2023, Alarm.com Incorporated, one of our wholly-owned subsidiaries, acquired certain assets of Vintra, Inc., or Vintra. Substantially all of the acquired assets consisted of developed technology. We believe the acquisition of the developed technology will expand Alarm.com's learning program and accelerate deployment of advanced video analytics solutions for the Alarm.com and OpenEye platforms. In consideration for the purchase of the acquired assets, we paid $5.5 million in cash on April 21, 2023, after deducting $0.3 million related to the settlement of an outstanding loan issued to Vintra during March 2023 and $1.0 million related to an agreed holdback provision. The holdback was paid during the third quarter of 2024. Additionally, we incurred $0.4 million in direct transaction costs related to legal fees during 2023 that were capitalized as a component of the consideration transferred. The $7.1 million purchase price consideration allocated to developed technology was recorded as an intangible asset at the time of the asset acquisition and is being amortized on a straight-line basis over an estimated useful life of five years. The remaining $0.1 million purchase price consideration was allocated to property and equipment. Acquisition of a Business - EBS On January 18, 2023, one of our wholly-owned subsidiaries acquired 100% of the issued and outstanding shares of capital stock of EBS Spółka z ograniczoną odpowiedzialnością, or EBS, an international producer of universal smart communicator devices, headquartered in Warsaw, Poland. We believe this acquisition will assist in the continued expansion of our international operations as well as benefit our supply chain operations. In consideration for the purchase of EBS, we paid $9.8 million in cash on January 18, 2023, after deducting $2.2 million related to agreed holdback provisions. An earn-out up to an additional $2.5 million is payable if certain performance targets are met, which was initially recorded at the acquisition date fair value of $2.0 million. The acquisition was accounted for as a business combination within our Alarm.com segment. The purchase price allocation was finalized during the third quarter of 2023. The overall impacts to our condensed consolidated financial statements were not considered material during the year of the acquisition.

Deferred Costs, Capitalized, Prepaid, and Other Assets Disclosure [Abstract]
Other Assets	Other Assets Loan to a Distribution Partner In December 2022, we amended a subordinated credit agreement with the affiliated entity of one of our distribution partners, or the Affiliate. The amended subordinated credit agreement with the Affiliate matures on June 18, 2027 and interest on the outstanding principal balance accrues at a rate of 12.0% per annum and is payable in kind. In March 2024, the Affiliate was in default on a loan arrangement with one of its third party secured lenders. Based on this information from the Affiliate, during the three months ended March 31, 2024, we recorded a credit loss expense of $4.0 million in general and administrative expense and recorded a reduction to our interest income of $0.5 million related to the reversal of payable in kind interest associated with the subordinated credit agreement. We placed this loan in nonaccrual status and recorded a full allowance for credit losses for this note receivable as of March 31, 2024. During the three months ended June 30, 2024, we wrote off the entire $4.0 million outstanding note receivable balance and reversed the previously recorded allowance for credit losses. As of December 31, 2023, $4.5 million of the notes receivable balance related to the subordinated credit agreement was included in other assets in our condensed consolidated balance sheet. For the three and nine months ended September 30, 2024, we recognized $0.7 million and $2.0 million of revenue from the distribution partner associated with this loan, respectively, as compared to $0.9 million and $2.5 million for the same periods in the prior year. Loan to a Service Provider Partner 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 September 30, 2024 and December 31, 2023, $1.0 million of principal was outstanding from the service provider partner under the loan agreement. For the three and nine months ended September 30, 2024 and 2023, we recognized less than $0.1 million and $0.1 million, respectively, of revenue from the service provider partner associated with this loan. Loan to a Technology Partner In June 2022, we entered into a convertible promissory note with a technology partner, under which we agreed to loan the technology partner $1.5 million. Interest on the outstanding principal accrues at a rate per annum equal to 6.5%, starting one year from the effective date of the loan. Interest and principal payments are due on the maturity date of the loan, which is June 27, 2029, unless the loan is converted prior to the maturity date, which may occur upon a qualified financing event, as defined in the convertible promissory note, upon a sale of the technology partner or upon our election on the maturity date of the loan. As of September 30, 2024 and December 31, 2023, $1.5 million of principal was outstanding from the technology partner under the convertible promissory note. For the three and nine months ended September 30, 2024 and 2023, we did not record any revenue from the technology partner associated with this convertible promissory note. 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 September 30, 2024 and December 31, 2023, our investment in the hardware supplier was $5.6 million. Investments in Technology Partners In February 2021, we paid $5.0 million in cash to purchase 1,000,000 shares of Series B-2 Preferred Stock from a 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 measurement 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 September 30, 2024 and December 31, 2023, our investment in the technology partner was $5.7 million. In December 2022, we paid $5.1 million in cash to another technology partner to purchase 4,231,717 shares of its Series A Preferred Stock. The $5.1 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. As of September 30, 2024 and December 31, 2023, our investment in the technology partner was $5.1 million. Allowance for Credit Losses - Notes Receivable We identified one portfolio segment, loan receivables, for our notes receivable. We previously disclosed a hardware financing receivable portfolio segment; however, there has been no activity within that portfolio segment since 2022. There were 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 during the three and nine months ended September 30, 2024. 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 September 30, 2024 and December 31, 2023 was $0.2 million and $0.1 million, respectively, and is reflected in other current assets and other assets within our condensed consolidated balance sheets and excluded from the amortized cost basis of the notes receivable . During the nine months ended September 30, 2024, we recorded a reduction to our interest income of $0.5 million related to the reversal of payable in kind interest associated with a subordinated credit agreement with the Affiliate. We did not write off any accrued interest receivable during the three months ended September 30, 2024 or the three and nine months ended September 30, 2023. There were no purchases or sales of financial assets during the three and nine months ended September 30, 2024 and 2023. During the nine months ended September 30, 2024, we wrote off $4.0 million related to a note receivable that originated in 2017 with the Affiliate and reversed the previously recorded allowance for credit losses.

During the three and nine months ended September 30, 2024 and 2023, there was no interest income recognized related to notes receivable that were in nonaccrual status. As of September 30, 2024 and December 31, 2023, there were no notes receivable placed in nonaccrual status for which there was not a related allowance for credit losses. As of September 30, 2024 and December 31, 2023, there were no notes receivable that were 90 days or greater past due for which we continued to accrue interest income. Prepaid Expenses As of September 30, 2024 and December 31, 2023, $21.5 million and $14.6 million of prepaid expenses were included in other current assets, respectively, primarily related to software licenses, insurance, long lead-time parts related to our inventory and our office leases.

Fair Value Measurements	Fair Value Measurements The following tables present our assets and liabilities measured at fair value on a recurring basis (in thousands): Fair Value Measurements on a Recurring Basis Assets: Level 1 Level 2 Level 3 Total Money market accounts as of September 30, 2024 $ 1,164,218 $ — $ — $ 1,164,218 Equity securities with readily determinable fair value as of September 30, 2024 5,349 — — 5,349 Money market accounts as of December 31, 2023 679,734 — — 679,734 Liabilities: Contingent consideration liability from acquisition as of September 30, 2024 $ — $ — $ 2,166 $ 2,166 Contingent consideration liability from acquisition as of December 31, 2023 — — 2,061 2,061 The following table summarizes the change in fair value of the Level 3 contingent consideration liability with significant unobservable inputs (in thousands): Three Months Ended Nine Months Ended 2024 2023 2024 2023 Beginning of period balance $ 2,105 $ 2,020 $ 2,061 $ — Acquired liabilities — — — 1,993 Changes in fair value included in earnings 61 (4) 105 23 End of period balance $ 2,166 $ 2,016 $ 2,166 $ 2,016 As of September 30, 2024, $1.16 billion of our money market accounts was included in cash and cash equivalents, $6.0 million was included in other assets and $1.9 million was included in other current assets in our condensed consolidated balance sheets. As of December 31, 2023, $675.6 million of our money market accounts was included in cash and cash equivalents and $4.1 million was included in other assets in our condensed consolidated balance sheets. Our assets from money market accounts are valued using quoted prices in active markets. Our equity securities with readily determinable fair value represent our investments in publicly traded companies, which are valued using quoted prices in active markets. During the three and nine months ended September 30, 2024, we recorded an unrealized loss on equity securities of $0.2 million. Our investments in public entities are recorded at fair value within other current assets in our condensed consolidated balance sheets and changes in fair value of the investments are recorded within other expense, net within our condensed consolidated statements of operations. See Note 12 for the carrying amounts and estimated fair values of our convertible senior notes as of September 30, 2024 and December 31, 2023. The contingent consideration liability consists of the potential earn-out payment related to our acquisition of 100% of the issued and outstanding capital stock of EBS on January 18, 2023. The earn-out payment is contingent on the satisfaction of certain performance targets related to the integration of EBS's hardware into the Alarm.com platform by December 31, 2025 and has a maximum potential payment of up to $2.5 million. We account for the contingent consideration using fair value and established a liability for the future earn-out payment based on an estimation of the probability of the future achievement of the performance targets. The contingent consideration liability was valued with Level 3 unobservable inputs, including the probability of expected achievement of the performance targets. At January 18, 2023, the fair value of the liability was $2.0 million. At each reporting date until December 31, 2025, or the achievement of the performance targets, we will remeasure the liability, using the same valuation approach. The fair value of the contingent consideration liability is included within accounts payable, accrued expenses and other current liabilities as well as other liabilities within our condensed consolidated balance sheets. Changes in fair value resulting from information that existed subsequent to the acquisition date are recorded in general and administrative expense in the condensed consolidated statements of operations. During the three and nine months ended September 30, 2024, the contingent consideration liability did not materially change from the acquisition date fair value of $2.0 million as there were minor changes in the expected probability of achievement for the performance targets. The unobservable inputs used in the valuation as of September 30, 2024 included a weighted average expected achievement percentage of 89.5%, weighted by the potential payout of the performance targets, including a range of 80.0% to 99.0%. The valuation also included a weighted average discount rate of 5.5%, weighted by the probability of achievement of the performance targets at various dates, including a range of 5.3% to 5.6%. Selecting another probability of expected achievement or discount rate within an acceptable range would not result in a significant change to the fair value of the contingent consideration liability. 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 into or out of Level 3 or reclassifications between levels of the fair value hierarchy during the three and nine months ended September 30, 2024 and 2023.

Leases [Abstract]
Leases	Leases As of September 30, 2024, we leased office space, data centers and office equipment under non-cancelable operating leases with various expiration dates through 2034. In August 2014, we signed a lease for office space in Tysons, Virginia, where we relocated our corporate headquarters to in February 2016. We have subsequently entered into amendments to this lease to provide us with additional office space as well as tenant improvement allowances. In August 2024, we entered into an amendment to the lease for our corporate headquarters, which extends the term of our existing leased office space to 2034 and includes two successive five-year renewal options. Additionally, the amendment provides for additional office space, parking spaces and tenant improvement allowances. Supplemental information related to leases is presented in the table below (in thousands, except weighted-average term and discount rate): Three Months Ended Nine Months Ended 2024 2023 2024 2023 Operating lease cost $ 3,472 $ 2,919 $ 9,425 $ 8,540 Cash paid for amounts included in the measurement of operating lease liabilities 2,420 3,533 9,171 10,329 Operating lease right-of-use assets obtained in exchange for new operating lease liabilities 34,434 1,214 37,349 5,329 September 30, December 31, Weighted-average remaining lease term — operating leases 8.1 years 3.0 years Weighted-average discount rate — operating leases 8.2 % 4.9 % Maturities of lease liabilities are as follows (in thousands): Year Ended December 31, Operating Leases (1) Remainder of 2024 $ 3,289 2025 12,659 2026 11,335 2027 11,566 2028 11,293 2029 and thereafter 54,510 Total lease payments 104,652 Less: imputed interest (2) 31,096 Present value of lease liabilities $ 73,556 _______________ (1) Excludes $18.3 million of legally binding minimum lease payments for leases executed but not yet commenced. There are no options to extend lease terms that were reasonably certain of being exercised included in these balances. (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 September 30, 2024 or December 31, 2023. 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 nine months ended September 30, 2024 and 2023.

Debt, Commitments and Contingencies Disclosure [Abstract]
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 - 2026 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 2026 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 2026 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 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 2026 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 2026 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 2026 Indenture), as the case may be. If we undergo a fundamental change (as defined in the 2026 Indenture), subject to certain exceptions and except as described in the 2026 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 2026 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, which was terminated 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. We account for the 2026 Notes as a liability. The debt issuance costs are presented as a deduction from the outstanding principal balance of the 2026 Notes and are amortized to interest expense using the effective interest method over the contractual term of the 2026 Notes at a rate of 0.6%. As of September 30, 2024 and December 31, 2023, the fair value of our 2026 Notes was $466.7 million and $444.8 million, respectively. 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 $54.67 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 September 30, 2024. The net carrying amount of the liability component of the 2026 Notes is as follows (in thousands): September 30, December 31, Principal $ 500,000 $ 500,000 Unamortized debt issuance costs (4,113) (6,485) Net carrying amount $ 495,887 $ 493,515 Interest expense related to the 2026 Notes is as follows (in thousands): Three Months Ended Nine Months Ended 2024 2023 2024 2023 Amortization of debt issuance costs $ 791 $ 787 $ 2,372 $ 2,357 Total interest expense $ 791 $ 787 $ 2,372 $ 2,357 Convertible Senior Notes - 2029 Notes On May 31, 2024, we issued $500.0 million aggregate principal amount of 2.25% convertible senior notes due June 1, 2029 in a private placement to qualified institutional buyers, or the 2029 Notes. The terms of the 2029 Notes are governed by an Indenture, or the 2029 Indenture, by and between Alarm.com Holdings, Inc. and U.S. Bank Trust Company, National Association, as trustee. The 2029 Notes are senior unsecured obligations that bear interest at a rate of 2.25% per annum, payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2024, and the principal amount of the 2029 Notes will not accrete. We received proceeds from the issuance of the 2029 Notes of $485.2 million, net of $14.8 million of transaction fees and other debt issuance costs. We may redeem for cash, all or any portion of the 2029 Notes (subject to the partial redemption limitation described below), at our option, on or after June 7, 2027, at a redemption price equal to 100% of the principal amount of the 2029 Notes to be redeemed, plus accrued and unpaid 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 2029 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. If we redeem less than all the 2029 Notes, at least $75.0 million aggregate principal amount of the 2029 Notes must be outstanding and not subject to redemption as of the relevant redemption notice date. No sinking fund is provided for the 2029 Notes. The 2029 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 January 1, 2029, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2024 (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 2029 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 2029 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 2029 Notes on each such trading day; (3) if we call any or all of the 2029 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 2029 Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events as set forth in the 2029 Indenture. On or after January 1, 2029, until the close of business on the second scheduled trading day immediately preceding the maturity date of the 2029 Notes, holders of the 2029 Notes may convert all or any portion of their 2029 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 2029 Notes with cash. The initial conversion rate for the 2029 Notes is 11.4571 shares of our common stock per $1,000 principal amount of 2029 Notes, which is equivalent to an initial conversion price of $87.28 per share of our common stock, subject to adjustment under certain circumstances in accordance with the terms of the 2029 Indenture. In addition, following certain corporate events that occur prior to the maturity date of the 2029 Notes or if we deliver a notice of redemption in respect of some or all of the 2029 Notes, we will, under certain circumstances, increase the conversion rate of the 2029 Notes for a holder who elects to convert its 2029 Notes (or any portion thereof) in connection with such a corporate event or convert its 2029 Notes called (or deemed called) for redemption during the related redemption period (as defined in the 2029 Indenture), as the case may be. If we undergo a fundamental change (as defined in the 2029 Indenture), subject to certain exceptions and except as described in the 2029 Indenture, holders may require us to repurchase for cash all or any portion of their 2029 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2029 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. The 2029 Indenture includes customary covenants and sets forth certain events of default after which the 2029 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 2029 Notes become automatically due and payable. We used $63.1 million of the net proceeds from the 2029 Notes to pay the cost of the capped call transactions described below and used $75.0 million to repurchase 1,117,068 shares of our common stock concurrently with the pricing of the 2029 Notes, which was separately authorized by our board of directors. We are using the remaining net proceeds from the issuance of the 2029 Notes for general corporate purposes, which may include acquisitions or strategic investments in complementary businesses or technologies, other repurchases of our common stock, repurchases of our 2026 Notes and for working capital, operating expenses and capital expenditures. We account for the 2029 Notes as a liability. The debt issuance costs are presented as a deduction from the outstanding principal balance of the 2029 Notes and are amortized to interest expense using the effective interest method over the contractual term of the 2029 Notes at a rate of 2.9%. As of September 30, 2024, the fair value of our 2029 Notes was $477.9 million. The fair value was determined based on the quoted price of the 2029 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 $54.67 on the last trading day of the quarter, the if-converted value of the 2029 Notes did not exceed the principal amount of $500.0 million as of September 30, 2024. The net carrying amount of the liability component of the 2029 Notes is as follows (in thousands): September 30, December 31, Principal $ 500,000 $ — Unamortized debt issuance costs (13,910) — Net carrying amount $ 486,090 $ — Interest expense related to the 2029 Notes is as follows (in thousands): Three Months Ended Nine Months Ended 2024 2023 2024 2023 Interest expense $ 2,812 $ — $ 3,750 $ — Amortization of debt issuance costs 694 — 924 — Total interest expense $ 3,506 $ — $ 4,674 $ — Capped Call – 2029 Notes In connection with the offering of the 2029 Notes, we entered into privately negotiated capped call transactions with one of the initial purchasers and certain other financial institutions, at a cost of $63.1 million. The capped call transactions cover, subject to customary adjustments substantially similar to those applicable to the 2029 Notes, the number of shares of our common stock initially underlying the 2029 Notes. The cap price of the capped call transactions is initially $134.28 per share of our common stock, which represents a premium of 100% over the closing price of our common stock on the Nasdaq Global Select Market on May 28, 2024, and is subject to certain adjustments under the terms of the capped call transactions. The exercise price is $87.28 per share of common stock, subject to customary anti-dilution adjustments that mirror corresponding adjustments for the 2029 Notes. We elected to integrate the capped call options with the 2029 Notes for federal income tax purposes pursuant to applicable U.S. Treasury Regulations. Accordingly, the $63.1 million cost of the purchased capped calls will be deductible for income tax purposes. The original issue discount is accreted over the term of the 2029 Notes. The capped call transactions are generally expected to reduce the potential dilution to holders of our common stock upon any conversion of the 2029 Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted 2029 Notes, as the case may be, with such reduction and/or offset subject to a cap. As the capped call options are both legally detachable and separately exercisable from the 2029 Notes, we account for the capped call options separately from the 2029 Notes. The capped call options are indexed to our own common stock and classified in stockholders’ equity. As such, the premiums paid for the capped call options were included as a net reduction to additional paid-in capital in the condensed consolidated balance sheets. The capped call transactions will not be remeasured as long as they continue to meet the conditions for equity classification. Commitments and Contingencies 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 January 10, 2022, EcoFactor, Inc., or EcoFactor, filed a lawsuit against us in U.S. District Court, District of Oregon, alleging Alarm.com’s products and services directly and indirectly infringe five U.S. patents owned by EcoFactor. EcoFactor is seeking a permanent injunction, enhanced damages and attorneys' fees. EcoFactor had previously asserted two of the same patents against us in an October 2019 complaint with the U.S. International Trade Commission, or ITC. In July 2021, the ITC found in favor of Alarm.com. EcoFactor appealed the decision but withdrew its appeal in December 2021. We moved to dismiss the Oregon case for failure to state a claim on March 28, 2022. Three of the asserted patents are in ex parte reexamination proceedings at the PTO, and ex parte reexamination of a fourth patent concluded on August 23, 2023 after the claims were amended. On April 18, 2022, all claims of a fifth patent were found unpatentable by the U.S. Patent Trial and Appeal Board, or PTAB, in an inter partes review, and all claims were canceled on February 1, 2024. On April 18, 2022, the district court stayed the case at the request of the parties pending the disposition of PTAB and other proceedings involving the asserted patents. Should EcoFactor prevail in its 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 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. We have not yet responded to the complaint. On September 3, 2021, the court issued an order staying the lawsuit until the ITC investigation described below is finally resolved. 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. On August 27, 2021, the ITC instituted an investigation into Causam’s allegations naming Alarm.com Incorporated, Alarm.com Holdings, Inc., EnergyHub Inc. and others as respondents. We answered the complaint on October 4, 2021. Among other things, we asserted defenses based on non-infringement and invalidity of the patents in question. An evidentiary hearing in the investigation was held from June 28, 2022 through July 1, 2022. On February 16, 2023, the ITC issued a final decision in favor of Alarm.com and EnergyHub. Causam filed an appeal of the ITC decision on April 14, 2023. Causam did not appeal the ITC decision with respect to Alarm.com and EnergyHub. 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 incur costs associated with the indemnification of our service provider Central Security Group – Nationwide, Inc. (d/b/a Alert 360), or CSG, in an ongoing patent litigation. In 2018, Ubiquitous Connectivity, LP, or Ubiquitous, brought suit against CSG in U.S. District Court, Northern District of Oklahoma, alleging infringement of two U.S. patents. The case was stayed by agreement of the parties for several years while the patents in suit were challenged before the PTAB. In January 2021, the PTAB deemed 42 out of 46 claims of the two asserted patents unpatentable. Ubiquitous appealed a portion of the PTAB’s findings to the United States Court of Appeals for the Federal Circuit. The Federal Circuit affirmed the PTAB’s ruling on August 8, 2023. As a result, only four patent claims remain at issue and the Northern District of Oklahoma case is no longer stayed. The case is currently in the discovery and claim construction phase. A claim construction hearing is scheduled for December 12, 2024. A hearing on dispositive motions, including for summary judgment, is scheduled for April 15, 2026. A trial is scheduled for July 6, 2026. Should Ubiquitous prevail on its infringement claims, we could be required to indemnify CSG for damages in the form of a reasonable royalty or of Ubiquitous’s lost profits. CSG 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 if 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. The outcome of these legal claims cannot be predicted with certainty. 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.

Equity [Abstract]
Stockholders' Equity	Stockholders' Equity Stock Repurchase Programs On February 15, 2023, our board of directors authorized a stock repurchase program, effective February 23, 2023, under which we were authorized to purchase up to an aggregate of $100.0 million of our outstanding common stock during the two-year period ending February 23, 2025. On May 24, 2024, our board of directors authorized the repurchase of our common stock in connection with the issuance of the 2029 Notes, the cancellation of the balance under the stock repurchase program ending February 23, 2025 and also authorized a stock repurchase program, effective May 31, 2024, under which we are authorized to purchase up to an aggregate of $100.0 million of our outstanding common stock during the two-year period ending May 31, 2026. The full repurchase balance for this program of $100.0 million was available as of September 30, 2024. No shares were repurchased under our stock repurchase program during the three months ended September 30, 2024. During the nine months ended September 30, 2024, 1,117,068 shares were repurchased for $75.0 million under our stock repurchase program. During the three and nine months ended September 30, 2023, 105,285 and 239,540 shares of our common stock were repurchased for $6.2 million and $12.9 million, respectively, under our stock repurchase program that was subsequently canceled effective May 31, 2024. As of January 1, 2023, we are subject to a 1.0% excise tax on the value of net corporate stock repurchases under the Inflation Reduction Act of 2022. When applicable, the excise tax will be included as part of the cost basis of shares acquired and is presented within stockholders’ equity in the condensed consolidated balance sheets. Shares Withheld As permitted under the terms of the 2015 Equity Incentive Plan, in 2021 the Compensation Committee authorized the withholding of shares of common stock in connection with the vesting of restricted stock unit awards issued to employees to satisfy applicable tax withholding requirements. These withheld shares are not issued or considered common stock repurchases under our stock repurchase program. No payments of tax withholdings were made related to vesting of restricted stock units during the three months ended September 30, 2024. We paid $3.4 million of tax withholdings related to vesting of restricted stock units during the nine months ended September 30, 2024. No tax withholdings related to the vesting of restricted stock units were paid during the three and nine months ended September 30, 2023. We also utilized the sell-to-cover method in which shares of our restricted stock unit awards were sold into the market on behalf of the employee upon vesting to cover tax withholding liabilities. We may utilize either the withholding method or sell-to-cover method in the future.

We use the treasury stock method when calculating the dilutive impact of the stock options and restricted stock units on net income per share. We use the if-converted method when calculating the dilutive impact of the 2026 Notes and 2029 Notes on net income per share. As a result, we included 3,396,950 shares related to the 2026 Notes within the weighted average shares outstanding when calculating the diluted net income per share for each of the three and nine months ended September 30, 2024 and 2023. We included 5,728,550 and 2,571,575 shares related to the 2029 Notes within the weighted average shares outstanding when calculating the diluted net income per share for each of the three and nine months ended September 30, 2024, respectively. Additionally, we included $3.2 million and $5.3 million of interest expense and debt issuance cost amortization, net of tax, within the numerator of the diluted net income per share for the three and nine months ended September 30, 2024, respectively, as compared to $0.6 million and $1.8 million for the same periods in the prior year. The denominator for diluted net income per share does not include any effect from the capped call transactions we entered into concurrently with the issuance of the 2029 Notes, as this effect would be anti-dilutive. In the event of conversion of the 2029 Notes, shares delivered to us under the capped call will offset the dilutive effect of the shares that we would issue under the 2029 Notes. See Note 12 for further details on our 2029 Notes and the related capped call transactions.

Income Taxes

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 nine months ended September 30, 2024, we recorded a provision for income taxes of $6.7 million and $10.3 million, respectively, resulting in an effective income tax rate of 15.6% and 10.1% for those periods. For the three and nine months ended September 30, 2023, we recorded a provision for income taxes of $4.0 million and $9.3 million, respectively, resulting in an effective income tax rate of 17.0% and 15.8% for those periods. For the three months ended September 30, 2024, our effective tax rate was below the 21.0% statutory rate primarily due to 2024 research and development tax credits claimed, the foreign derived intangible income deduction and a favorable true-up adjustment of our 2023 income tax provision estimate and amended prior year state income tax returns, partially offset by the impact of state taxes, foreign withholding taxes and other nondeductible expenses. For the nine months ended September 30, 2024, our effective tax rate was below the 21.0% statutory rate primarily due to a favorable true-up adjustment of our 2023 income tax provision estimate, the foreign derived intangible income deduction, 2024 research and development tax credits claimed, the release of an unrecognized tax benefit liability due to the closure of the 2018 and 2019 Internal Revenue Service federal income tax examination and tax windfall benefits from employee stock-based compensation, partially offset by the impact of state taxes, federal estimated tax payment interest expense and other nondeductible expenses. For the three months ended September 30, 2023, our effective tax rate was below the 21.0% statutory rate primarily due to research and development tax credits claimed, the foreign derived intangible income deduction and a favorable true-up adjustment of our 2022 income tax provision estimate, partially offset by the impact of state taxes, foreign withholding taxes and a stock-based compensation tax shortfall. For the nine months ended September 30, 2023, our effective tax rate was below the 21.0% statutory rate primarily due to research and development tax credits claimed and the foreign derived intangible income deduction, partially offset by an unfavorable true-up adjustment of our 2022 income tax provision estimate associated with research and development tax credits, the impact of state taxes, foreign withholding taxes, other nondeductible expenses and a stock-based compensation tax shortfall. 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. Our valuation allowance for state research and development tax credit carryforwards and net deferred tax assets of our EBS subsidiary was $3.8 million as of December 31, 2023 and increased to $4.2 million as of September 30, 2024. 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 a net increase to the unrecognized tax benefits liability of less than $0.1 million primarily due to a liability for research and development tax credits claimed, partially offset by the closure of the 2018 and 2019 Internal Revenue Service federal income tax return examination and the release of a state unrecognized tax benefit liability due to the statute of limitations expiration during the nine months ended September 30, 2024. We recorded a net increase to the unrecognized tax benefits liability of $1.1 million primarily for research and development tax credits claimed during the nine months ended September 30, 2023. Our condensed consolidated balance sheets included an accrual for total interest expense related to unrecognized tax benefits of $0.8 million as of December 31, 2023 and September 30, 2024. We recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. Our tax returns are subject to on-going review and examination by various tax authorities. Tax authorities may not agree with the treatment of items reported in our tax returns, and therefore the outcome of tax reviews and examinations can be unpredictable. On October 13, 2021, the Internal Revenue Service commenced an examination of our federal income tax return for 2018 and on August 12, 2022, the Internal Revenue Service expanded the examination to include our federal income tax return for 2019. On January 25, 2024, the Internal Revenue Service notified us that the income tax examination of our 2018 and 2019 federal income tax returns has been closed. As a result, we paid $0.6 million in additional federal taxes, including interest, during the three months ended June 30, 2024, and recognized a net income tax benefit of $1.7 million during the three months ended March 31, 2024. As of September 30, 2024, we did not have material undistributed foreign earnings. We have not recorded a deferred tax liability on the undistributed earnings from our foreign subsidiaries, as such earnings are considered to be indefinitely reinvested. In August 2022, the Inflation Reduction Act of 2022 was enacted in the United States which, among other provisions, includes a minimum 15.0% tax on companies that have a three-year average annual adjusted financial statement income of more than $1.0 billion and a 1.0% excise tax on the value of net corporate stock repurchases. Both provisions became effective on January 1, 2023 and the provisions did not have a material impact on our financial condition or results of operations for the periods presented.

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, 2023 included in our Annual Report on Form 10-K filed with the SEC on February 22, 2024, or the Annual Report. The condensed consolidated balance sheet as of December 31, 2023 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 global economy, credit markets and financial markets have and may continue to experience significant volatility as a result of significant worldwide events, including public health crises, and geopolitical upheaval, such as Russia’s incursion into Ukraine and the conflict between Israel and regional adversaries, disruptions to global supply chains, rising interest rates, risk of recession and inflation (collectively, the Macroeconomic Conditions). These Macroeconomic Conditions have and may continue to create supply chain disruptions, inventory disruptions, and fluctuations in economic growth, including fluctuations in employment rates, inflation, energy prices and consumer sentiment. It remains difficult to assess or predict the ultimate duration and economic impact of the Macroeconomic Conditions. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that can be expected for our entire fiscal year ending December 31, 2024, which is increasingly true in periods of extreme uncertainty, such as the uncertainty caused by the Macroeconomic Conditions. Prolonged uncertainties 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	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 Macroeconomic Conditions, 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, goodwill, intangible assets and other long-lived assets.
Capped Call Transactions	Capped Call Transactions On May 31, 2024, we issued $500.0 million aggregate principal amount of 2.25% convertible senior notes due June 1, 2029 in a private placement to qualified institutional buyers, or the 2029 Notes. In connection with the offering of the 2029 Notes, we entered into privately negotiated capped call transactions with one of the initial purchasers and certain other financial institutions, at a cost of $63.1 million. The capped call transactions cover, subject to customary adjustments substantially similar to those applicable to the 2029 Notes, the number of shares of our common stock initially underlying the 2029 Notes. As the capped call options are both legally detachable and separately exercisable from the 2029 Notes, we account for the capped call options separately from the 2029 Notes. The capped call options are indexed to our own common stock and classified in stockholders’ equity. As such, the premiums paid for the capped call options were included as a net reduction to additional paid-in capital in the condensed consolidated balance sheets. The capped call transactions will not be remeasured as long as they continue to meet the conditions for equity classification. We elected to integrate the capped call options with the 2029 Notes for federal income tax purposes pursuant to applicable U.S. Treasury Regulations. Accordingly, the $63.1 million cost of the purchased capped calls will be deductible for income tax purposes. The original issue discount is accreted over the term of the 2029 Notes.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted During the three and nine months ended September 30, 2024, we did not adopt any new accounting pronouncements. Not Yet Adopted On November 27, 2023, the Financial Accounting Standards Board, or FASB, issued ASU 2023-07, "Segment Reporting (Topic 280),” which revises the disclosure requirements about a public entity’s reportable segments and a reportable segment’s expenses. This amendment requires a public entity to (i) disclose significant segment expense that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, (ii) disclose an amount for other segment items by reportable segment and a description of its composition and (iii) provide annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 in interim periods. The amendment is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. This amendment is required to be applied retrospectively to all prior periods presented. We expect this amendment to increase the amount of disclosures we provide within Note 18 related to segment expenses in the annual reporting period ending December 31, 2024 and interim reporting periods thereafter. On December 14, 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740)," which requires additional annual disclosures regarding specific categories in the income tax rate reconciliation as well additional information for reconciling items that meet a quantitative threshold. This amendment also requires annual disclosures regarding the amount of income taxes paid, including income taxes paid disaggregated by (i) federal, state and foreign taxes as well as (ii) individual jurisdictions in which income taxes paid is equal to or greater than five percent of total income taxes paid. Additionally, this amendment requires annual disclosures for income from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign as well as income tax expense (or benefit) disaggregated between federal, state and foreign. The amendment is effective for annual periods beginning after December 15, 2024, and early adoption is permitted. This amendment should be applied on a prospective basis, but retrospective application is permitted. We are currently assessing the impact this pronouncement will have on our consolidated financial statement disclosures. On November 5, 2024, the FASB issued ASU 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)," which requires more detailed information about the types of expenses included in certain expense captions presented on the consolidated statements of operations, including purchases of inventory, employee compensation, depreciation, amortization and depletion. Additionally, this amendment requires the disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and the disclosure of the total amount of selling expenses and, on an annual basis, an entity's definition of selling expenses. The amendment is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. This amendment should be applied either on a prospective basis or a retrospective basis to any or all prior periods presented. We are currently assessing the impact this pronouncement will have on our consolidated financial statement disclosures.
Allowance for Credit Losses	Allowance for Credit Losses 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. 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 months ended September 30, 2024, we recorded a reduction to credit loss expense for accounts receivable and notes receivable of $0.1 million and for the nine months ended September 30, 2024, we recorded credit loss expense for accounts receivable and notes receivable of $4.1 million, in general and administrative expense in our condensed consolidated statements of operations. For the three and nine months ended September 30, 2023, we recorded credit loss expense for accounts receivable and notes receivable of $0.6 million and $1.1 million, respectively, 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. Allowance for Credit Losses - Accounts Receivable 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 nine months ended September 30, 2024, and no changes to our policies or practices that influenced our estimate of expected credit losses for accounts receivable. Additionally, there were no significant changes in the amount of accounts receivable write-offs during the three and nine months ended September 30, 2024, as compared to historical periods. Allowance for Credit Losses - Notes Receivable We identified one portfolio segment, loan receivables, for our notes receivable. We previously disclosed a hardware financing receivable portfolio segment; however, there has been no activity within that portfolio segment since 2022. There were 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 during the three and nine months ended September 30, 2024. 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
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. Our valuation allowance for state research and development tax credit carryforwards and net deferred tax assets of our EBS subsidiary was $3.8 million as of December 31, 2023 and increased to $4.2 million as of September 30, 2024.
