ADT started 2026 with a strong first quarter, headlined by adjusted free cash flow of $414 million, up more than 80% year-over-year, and adjusted EPS of $0.23, up 10%. The company advanced its three investment priorities of product technology, service excellence and customer acquisition, expanding ADT+ to ~30% of new additions, launching Live Light and MySafety, and progressing the Origin AI integration. Top-line growth remained muted, with revenue up 1% and RMR flat, while attrition held at an elevated 13.1%.
Good morning, and thank you for joining us today to discuss ADT's first quarter 2026 results. Speaking on today's call are Jim DeVries, our Chairman, President, and Chief Executive Officer, and Jeff Likosar, our Chief Financial Officer. Following their prepared remarks, we'll be joined by Omar Khan, our Chief Business Officer, and we'll open the call for analyst questions. Earlier today, we issued a press release and an earnings presentation summarizing our results. Both are available on the investor relations section of our website. During today's call, we'll reference certain non-GAAP financial measures. Reconciliation to the most comparable GAAP measures can be found in the earnings presentation. Unless otherwise noted, all financials and metrics discussed reflect continuing operations. Our remarks today also include forward-looking statements made under the Safe Harbor provisions of the Private Securities Litigation Reform Act.
These statements are subject to risks and uncertainties that are described in the earnings presentation and in our SEC filings. Actual results may differ materially. Please refer to our SEC filings for more details. With that, I'm happy to turn the call over to Jim.
Thank you, Elizabeth. Good morning, everyone, and thank you for joining us today. I'll focus my remarks this morning mainly on the key highlights from our first quarter. I will also build on the strategic update and longer-range outlook we shared on our last call in March. I'll turn the call over to Jeff to walk through our financials and outlook. Let me start with a few key financial highlights. I'm pleased to report that ADT delivered a strong start to the year. Our results were consistent with our plans with particularly strong cash generation. Adjusted free cash flow, including swaps, was at $414 million, and adjusted earnings per diluted share was $0.23, up 10% year-over-year. Our durable recurring monthly revenue was $359 million, flat versus prior year.
Gross revenue attrition remained at 13.1%, and our revenue payback period was 2.3 years. Cumulatively, these results reinforce the durability of our model and progress strengthening ADT's business, prioritizing high-quality ads and more efficient acquisition channels. Turning to our key initiatives, the strategic update we shared on our last call emphasized the consistency in our overall mission. We also outlined how we are reshaping and redefining the delivery of smart home security. Our mission remains clear. To protect and connect what matters most and to provide our customers with peace of mind. Our overall strategy remains anchored in three core differentiators. Unrivaled safety, premium experience, and innovative offerings. As we described, during 2026, we are accelerating progress with investments in three key areas. Product technology, service excellence, and customer acquisition.
Together, these investments support our vision to deliver always-on security and convenience with split-second and proactive response and solutions that evolve with our customers, whether they're at home or away. First, on product technology. Our proprietary ADT+ platform continues to gain traction. ADT+ brings together professional monitoring with leading smart home devices, including Google Nest and Yale products, enabling a more flexible and modern experience for customers. In the first quarter, approximately 30% of our new customer additions included ADT+. We expect to continue expanding penetration of our ADT+ ecosystem and app to more channels, including, most importantly, our third-party network of dealers who will begin transitioning to ADT+ this summer. Dealers represented more than a third of our total gross additions last year. As they adopt ADT+, we expect more than two-thirds of new subscribers will be on our proprietary platform.
We also expanded ADT+ features in the first quarter with the launch of two new innovations that extend the platform's capabilities. Live Light is the industry's first illuminated wireless yard sign that directly connects to the ADT+ system and illuminates during an alarm event, giving first responders an immediate visual signal and letting potential intruders know a home is actively protected. MySafety is a personal mobile safety service in the ADT+ app that provides customers with the same protection they know and trust from ADT at home, but while they are on the go, including seamless connection to ADT's nationwide monitoring network wherever they are. We already have 35,000 customer activations. With innovative features such as these, ADT is improving security and demonstrating our belief that safety is not just about intrusion detection.
It's about awareness, visibility, and response, and most importantly, peace of mind. As discussed on our last call, we acquired Origin AI in February which will add AI-driven ambient intelligence technology into the ADT+ platform, creating a new layer of home intelligence. This privacy first, Wi-Fi based sensing technology allows customers to understand what's happening in their homes without cameras or wearables. Over time, this will become an integrated part of the ADT+ experience enabling richer resolution and awareness while continuing to protect our customers' privacy. Concurrent with this acquisition, we also entered into a long-term technology licensing agreement with Verisure reinforcing the global relevance and scalability of this platform and the practical use cases already deployed in Europe.
Since closing the acquisition, we are rapidly progressing both technical development and commercialization plans, and during the first quarter, we completed the design of a smart plug that will enable integration into our core offerings. Key priorities over the next two quarters include initial manufacturing and pilots of these smart plugs and technical development for integration into our ADT+ platform for security and aging in place use cases and integration into a third-party router. As we deepen our plans to deploy this sensing technology and work with the team, I'm even more excited about the role these capabilities will play in our evolution to proactive peace of mind. Next, our second area of investment, service excellence. ADT's best-in-class team of employees continue to deliver outstanding service and support for our customers.
Alongside the AI-enabled features in our product offering, we are also increasingly using AI to deliver better service for our customers while delivering better economics for the business. We're deploying AI-powered virtual agents across both chat and voice interactions to improve responsiveness and consistency, enabling customers to get accurate answers faster while allowing our human teams to focus on the highest value customer interactions. As of the first quarter, all chat interactions and approximately half of our phone calls are initially routed through AI. Containment continues to improve, meaning more issues are resolved without any human intervention. These efforts are both improving the customer experience and beginning to structurally lower our cost base. Additionally, our unique combination of AI capabilities and human expertise have lifted our net promoter score.
We're also seeing record levels of customer self-service powered by an expansion of AI use cases, enabling deeper customer engagement and a significant reduction in high-cost field service appointments. Importantly, ADT employees continue to handle situations where human expertise matters most, such as during emergencies or when an on-site highly trained service technician is the best way to resolve a customer issue. Finally, our investment in customer acquisition. While ADT already enjoys the benefits of a very strong and trusted brand in a variety of routes to market, I'm excited about several areas we will advance this year. One highlight is our expansion into e-commerce with the launch of Blue by ADT, a new product line designed to appeal to more value conscious and DIY-oriented customers. This launch includes lower cost cameras, expanding our product portfolio, and enabling lower price points to appeal to a different segment of customers.
ADT Blue will debut on our own website in late May, and then in additional e-tail channels, including Amazon over the summer. We're excited to unlock these new routes to market and to begin targeting this segment of customers, which we believe represents incremental TAM. We anticipate more volume from more price conscious or DIY-oriented customers from this launch. While some prospective customers may choose these lower priced DIY solutions, we also envision converting a subset of them to our more traditional, professionally installed solutions. Additionally, we are continuing to drive efficiency in our overall go-to-market approach, including rationalization of our marketing spend and our highest cost channels. So far, we've lowered third-party affiliate lead fees by $100 per installation, and we're working on efficiency changes to our dealer model.
As I mentioned on our last call, these changes may temporarily impact subscriber additions, but they're designed to improve long-term efficiency. As we've shared previously, we will also continue to evaluate bulk account purchase options and potentially full acquisition opportunities in our industry at attractive economics. In closing, we remain focused on executing on these initiatives which we have outlined in positioning ADT for long-term value creation. I am confident in ADT's outlook and our ability to deliver on our commitments for 2026 and beyond. I want to thank our employees, partners, and customers for their dedication and trust in ADT. I'm proud of our team's performance and excited for the opportunities ahead. With that, I'll turn the call over to Jeff.
Thanks, Jim, and good morning, everyone. I will take the next few minutes to add some detail on our first quarter results and share an update on our outlook for the rest of the year and the second quarter. I'm very pleased with our start to 2026, which was consistent with our plans and the outlook we shared in March. As Jim mentioned, cash flow remains a significant highlight, and in the first quarter, we generated $414 million of adjusted free cash flow, including interest rate swaps, which was up $187 million or more than 80% versus last year. This result was driven primarily by lower cash interest, the timing of some payroll-related disbursements and other working capital items, and our overall profitability.
We continue to enjoy a very strong capital structure and liquidity position with our $800 million revolving credit facility and $119 million of cash available at the end of the quarter. Notably, this was after funding the Origin acquisition and returning $161 million to shareholders. Earlier this year, our board authorized a $1.5 billion three-year repurchase program, and during the first quarter, we retired approximately 18 million shares for $116 million. We do not believe our current stock price reflects the intrinsic value of our business and have therefore deployed additional capital towards share repurchases in April. Our year-to-date repurchases total approximately 35 million shares for $230 million.
Turning to earnings, adjusted EBITDA for the quarter was $674 million, up 2% versus last year, and adjusted earnings per share was $0.23, up 10%. This performance reflects the durability of our high-margin revenue and our overall efficiency across the business, allowing us to deliver solid results while also investing for the future. Our first quarter results also include a favorable legal settlement loss recovery, partially offset by an increase in our allowance for credit losses. In addition, earnings per share benefited from last year's share repurchases enabled by our cash generation and our efficient capital structure. On the top line, we delivered first quarter total revenue of $1.3 billion, up 1%. Monitoring and services revenue was relatively flat with an ending RMR balance of $359 million.
I will note our prior year results include the multifamily business we divested last October, which represented approximately 200,000 subscribers and $2.6 million of RMR. On a year-over-year basis, higher average pricing across our subscriber base largely offset the absence of multifamily revenue. Installation revenue in the quarter was $198 million, up 7%, reflecting a higher mix of outright equipment sales related to our transition to the ADT+ platform. We added 161,000 gross new subscribers with $10.1 million of RMR on lower cash SAC. We remain focused on delivering strong subscriber economics and returns on the capital we deploy and have consequently continued to balance SAC spending with other uses of cash. Our overall capital allocation priorities remain unchanged.
We are investing in the business where returns are compelling, both organically and via periodic acquisitions. We are returning capital directly to shareholders. We are maintaining a healthy balance sheet with an objective of further reducing leverage. After several refinancing and repayment transactions last year, our weighted average maturity is approximately five years, and our cost of debt is currently around 4.3%. We remain very comfortable with our current leverage at 2.7x adjusted EBITDA with net debt of $7.3 billion. Earlier this month, we repaid the remaining $75 million of our 2026 notes at maturity with our next maturity in August of next year. Before I conclude, I want to briefly reiterate the full year 2026 outlook we shared in March.
We expect very strong adjusted free cash flow growth of approximately 20% and revenue and adjusted EPS to be approximately flat to last year. This outlook reflects our ongoing prioritization of cash generation, disciplined subscriber acquisition spending, and share repurchase plans. It also incorporates planned investments benefiting future periods, which Jim described earlier, along with expected tariffs. For the second quarter, we expect revenue and EPS to be slightly lower than the first quarter, due primarily to higher advertising spending with the ADT Blue launch along with other initiative investments. We also expect adjusted free cash flow to be $100 million-$150 million lower sequentially due to higher seasonal SAC spending, the timing of working capital flows, and tax payments.
We're pleased with our strong start to the year and remain confident in our ability to deliver 2026 results while also investing in initiatives that generate growth in future years. Thank you again for joining our call today and for your continued support. Operator, please open the call to questions.
