One of the most recognizable names in the physical security industry is leaving the public markets. ADT Inc. announced Thursday it has agreed to be acquired by Thrive Holdings in an all-cash deal valued at $15.3 billion including debt, taking the 152-year-old home security giant private in one of the largest transactions the security industry has seen.

For anyone who has spent time in this industry, the news is significant. ADT is the brand against which virtually every residential security competitor has measured itself for generations.

ADT traces its roots to 1874, when founder Edward Callahan connected 50 homes in Baltimore via telegraph “call-box,” creating the first residential security network. Today, ADT serves more than six million customers with over 12,000 employees and operates the largest professional security monitoring network in the country.

How it got there – and where it goes next – is a story of relentless reinvention.

Apollo’s Decade-Long Run

To understand the deal, it is essential to understand what Apollo Global Management built with ADT and how it has been unwinding that position ever since.

Apollo’s involvement dates to 2015, when it acquired Protection 1. The following year, it combined that business with The ADT Corporation in an all-cash transaction valued at approximately $6.9 billion, also folding in ASG Security to create a single integrated national provider. The thesis was straightforward: consolidate the fragmented residential and commercial security space around the industry’s most recognizable name and its massive recurring monitoring revenue base.

The payoff came in January 2018, when ADT returned to the public markets at $14 per share, with Apollo retaining a significant majority stake. In the years since, Apollo gradually reduced its position through a series of secondary offerings, a process that concluded just this past May when the firm sold its remaining shares in a transaction valued at up to $770 million.

In exclusive interviews with SecurityInfoWatch at the time, Peter Giacalone of Giacalone Associates called the Apollo exit “long overdue,” while Kirk MacDowell of MacGuard Security Advisors described it as a natural conclusion to a disciplined investment cycle.

What makes Thursday’s announcement particularly notable: Apollo, now fully out of ADT equity, is providing all financing commitments for the Thrive Holdings acquisition. The firm that built ADT into its current form, took it public, and spent years unwinding its ownership stake is now bankrolling the deal that takes it private again.

Strategic Reinvention Under Public Ownership

ADT’s years as a public company were not static. The company has been aggressively reshaping what ADT is, and for whom.

The most significant strategic relationship to emerge in that period was a partnership with Google. In 2020, Google took a roughly 6% equity stake in ADT, and the relationship ultimately produced ADT Self Setup, the company’s first fully integrated DIY offering, launched in 2023. The product paired Google Nest hardware with ADT’s monitoring infrastructure and the ADT+ app, giving consumers a self-installed system backed by professional monitoring – ADT’s answer to the growing DIY security market that had been eating at its margins for years.

As SIW reported when the Google partnership began bearing fruit, the collaboration represented a meaningful pivot in how ADT was positioning itself competitively.

ADT also made a significant structural move by shedding its commercial business. In September 2025, Everon acquired ADT’s business-to-business multifamily operations for $55 million in cash, covering roughly 200,000 customer units across apartment buildings, student housing, military housing, and townhomes. Combined with the earlier divestiture of ADT’s full commercial business, ADT has been sharpening its focus on the residential market.

More recently, ADT has been migrating its technology infrastructure to Google Cloud and integrating artificial intelligence into its operations, a transition that analysts at RBC Capital Markets cited as meaningful progress in ADT’s business transformation. 

ADT also acquired Origin Wireless earlier this year, adding an AI-powered sensing platform capable of detecting motion and human presence without cameras, audio, or wearables – technology ADT has said it plans to incorporate into product offerings beginning in 2027.

State Farm entered the picture in 2022 as a major investor, reflecting the natural alignment between the country’s largest home insurer and a home security monitoring giant. After Apollo’s full exit in May, State Farm became ADT’s largest shareholder.

Who Is Thrive Holdings?

Reports of acquisition talks first surfaced Wednesday, with Thrive Capital identified as the potential buyer. The buyer is a permanent-capital company spun out of Josh Kushner’s Thrive Capital venture firm, with a stated mission of bringing artificial intelligence into traditionally analog industries across accounting, IT services, and what it calls the “built environment.”

Thrive Holdings plans to make ADT the foundation of its smart home security operations.

The permanent-capital structure matters. Unlike a traditional private equity fund with a defined exit timeline, Thrive Holdings is designed for long-term ownership – a different posture than what ADT has experienced through most of its recent history.

What It Means for the Channel

ADT has long anchored the dealer channel in residential security, and major ownership transitions typically bring shifts in how dealer programs are structured and where technology investment gets directed.

Market data supports ADT’s position entering this deal. According to Parks Associates, ADT holds roughly one-third of the installed base for security systems, with its share of recent buyers rising from 21% in Q4 2022 to 26% in Q4 2025 – a trend reflected in the company’s most recent quarterly results.

Elizabeth Parks of Parks Associates has characterized ADT as a differentiated asset in a market where providers are competing on AI, new service models, and platform expansion.

The DIY question has not gone away. Industry observers have noted for years that despite ADT’s brand strength and dealer network, the company has struggled to assert itself convincingly in the DIY segment. Whether Thrive Holdings – with its AI orientation and OpenAI connections – treats that as a priority or doubles down on the professional monitoring model will be one of the key strategic questions coming out of this deal.

Thrive Holdings has stated it intends to invest in ADT’s technology, products, and nationwide service network.

ADT will continue operating independently until the transaction closes, with existing customer data and privacy policies unchanged.

The deal is expected to close in the first quarter of 2027, pending shareholder approval and U.S. antitrust clearance. Shareholders will receive $10 per share in cash, representing a roughly 46% premium to ADT’s unaffected closing price. A 30-day window for competing acquisition proposals runs through November 28. Upon closing, ADT’s shares will be delisted from the NYSE.
