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. On January 14, 2026, we paid $500.0 million in aggregate principal amount to holders of the 2026 Notes, fully settling the outstanding balance in accordance with the repayment terms. As of December 31, 2025, the fair value of our 2026 Notes was $499.1 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 was classified as Level 2 in the fair value hierarchy. 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. As of June 30, 2026 and December 31, 2025, the fair value of our 2029 Notes was $475.2 million and $477.3 million, respectively. 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 $46.72 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 June 30, 2026. The net carrying amount of the liability component of the 2029 Notes is as follows (in thousands):

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. On April 18, 2022, the district court stayed the case at the request of the parties pending the disposition of other proceedings involving the asserted patents. These proceedings include four ex parte reexamination proceedings at the U.S. Patent and Trademark Office and one inter partes review. Three of the patents were found unpatentable in reexamination. The decision with respect to one of the patents was affirmed by the United States Court of Appeals for the Federal Circuit, or Federal Circuit, on January 21, 2026, EcoFactor filed an appeal of the decision with respect to the second patent with the Federal Circuit on November 20, 2025, and EcoFactor is appealing the rejection of the third patent to the Patent Trial and Appeal Board, or PTAB, having filed its appeal brief on June 10, 2024. 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 PTAB in inter partes review, and all claims were canceled on February 1, 2024. 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 3, 2025, SkyBell Technologies, Inc., or SkyBell, filed a lawsuit against us in U.S. District Court, Eastern District of Virginia, alleging that Alarm.com misappropriated SkyBell’s trade secrets relating to video doorbells. On May 26, 2026, SkyBell filed an amended complaint adding allegations that Alarm.com infringed copyrights in its computer source code. SkyBell is seeking injunctive relief, enhanced damages, attorneys’ fees, a constructive trust, and an order that Alarm.com assign to SkyBell the alleged trade secrets. On June 5, 2026, we filed an answer to the amended complaint denying any misappropriation of trade secrets or infringement of copyrights. Discovery is expected to be completed in September 2026. No trial date has been set. Should SkyBell 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, we could be required to pay ongoing royalties and comply with unfavorable terms if such a license is made available to us, and we could be required to assign, transfer, and return any SkyBell trade secret that we are found to improperly possess. While we believe we have valid defenses to SkyBell’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 Southern Electric Maryland Electric Cooperative, Inc., or SMECO, in an ongoing patent infringement suit. On May 26, 2026, Causam Enterprises, Inc. filed a lawsuit against SMECO in U.S. District Court, District of Maryland, alleging that SMECO infringes six patents owned by Causam relating to SMECO’s demand response program which includes, among other systems, the EnergyHub platform. Causam is seeking damages and attorneys’ fees. Should Causam prevail, we could be required to indemnify SMECO for damages if a license or other right to continue using 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. 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. 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. Tariff Matters On April 20, 2026, the U.S. Customs and Border Protection began accepting refund requests through its Consolidated Administration and Processing of Entries portal, and we subsequently filed for an estimated $14.5 million in tariffs previously paid under the International Emergency Economic Powers Act. During the three and six months ended June 30, 2026, we recorded less than one third of the estimated $14.5 million as a reduction to cost of hardware and other revenue and processed a commensurate amount of refunds to customers, excluding certain processing fees, as a reduction to hardware and other revenue. As of June 30, 2026, we have not recorded any additional receivables related to potential refunds for previous tariffs we paid because we are unable to assess the probability of their recovery.
