Resideo Technologies Inc. completed the spin-off of ADI Global Distribution Inc. on August 3, 2026. Resideo distributed all of its shares in ADI to existing Resideo shareholders on a pro-rata basis: one ADI share for every two Resideo shares held. ADI began trading on the New York Stock Exchange under the ticker symbol ADIG on August 4, 2026. Resideo continues to trade under the ticker REZI.

In connection with the spin-off, Resideo completed $900 million in debt repayment, simplifying its capital structure. ADI is now an independent public company with its own management team, capital structure, and investment strategy.

Resideo's core business is building technology — thermostats, sensors, security systems, and related products sold through professional installers and distributors. ADI Global Distribution is a distributor of security, audio-visual, and low-voltage products, serving professional installers and integrators across North America, Europe, and other markets.

While these businesses have historically operated under the same corporate umbrella, they have different customer bases, competitive dynamics, and capital allocation priorities. A distributor business requires working capital investment and benefits from scale in procurement and logistics. A technology products business requires R&D investment and benefits from brand strength and product differentiation.

By separating the two businesses, Resideo becomes a pure-play building technology company that can focus its capital and management attention on product development and its direct-to-installer distribution model. ADI becomes an independent distributor that can pursue its own M&A strategy — acquiring regional distributors or expanding into new product categories — without competing for capital allocation within a larger corporate structure.

The real legal work in a spin-off begins after the distribution date. The Separation and Distribution Agreement (SDA) — the master agreement governing the separation — establishes the framework that will govern the relationship between Resideo and ADI for years after the spin-off is complete.

The SDA is the foundational document of the spin-off. It defines:

Asset and liability allocation: Which assets, contracts, intellectual property, real estate, employees, and liabilities belong to Resideo and which belong to ADI. In a complex business separation, this allocation is rarely clean — there will be shared assets, contracts that serve both businesses, and liabilities whose origin is ambiguous.

Indemnification: Each company typically indemnifies the other for liabilities allocated to it under the SDA. If a pre-spin liability is later discovered and attributed to one company's business, that company bears the cost — even if the liability arose from conduct that occurred when both businesses were under the same corporate roof.

Transition services: For a period after the spin-off, one company may provide services to the other under a Transition Services Agreement (TSA). These services might include IT systems, finance and accounting support, HR administration, and shared facilities. The TSA defines the scope, pricing, and duration of these services, and the conditions under which they terminate.

Shared contracts: Many of Resideo's contracts with suppliers, customers, and service providers will have served both the Resideo and ADI businesses. These contracts must be either assigned to one company, split between the two companies, or replaced with separate contracts for each. The process of separating shared contracts is one of the most operationally intensive aspects of a spin-off.

Intellectual property: The SDA must address the allocation of patents, trademarks, trade secrets, and software between the two companies. Where IP is used by both businesses, the SDA may establish cross-licenses that allow each company to continue using the shared IP after separation.

For U.S. federal income tax purposes, Resideo's distribution of ADI shares to its shareholders is intended to qualify as a tax-free spin-off under Section 355 of the Internal Revenue Code. If the distribution qualifies, neither Resideo nor its shareholders recognize taxable income on the distribution.

The tax-free status of a spin-off depends on satisfying several requirements at the time of the distribution — including the active business requirement, the business purpose requirement, and the continuity of interest requirement. But it also depends on what happens after the distribution.

Post-spin acquisition restrictions: Section 355(e) of the Internal Revenue Code imposes a "anti-Morris Trust" rule: if, within two years after the distribution, either Resideo or ADI is acquired in a transaction in which 50% or more of its stock changes hands, the distribution may be treated as taxable. This rule is designed to prevent companies from using a tax-free spin-off as a step in a larger taxable acquisition.

The practical consequence is that both Resideo and ADI are subject to significant constraints on their ability to engage in M&A transactions for two years after the August 3, 2026 distribution date. Any acquisition of either company — or any acquisition by either company that involves issuing more than 50% of its stock — must be carefully analyzed for its impact on the tax-free status of the spin-off.

Restricted stock issuances: Similarly, both companies must be careful about issuing stock in connection with employee compensation plans, acquisitions, or financing transactions during the two-year restricted period.

Tax sharing agreement: The SDA will include a tax sharing agreement that allocates responsibility for pre-spin tax liabilities between Resideo and ADI, and that establishes procedures for filing tax returns, handling tax audits, and indemnifying each other for tax liabilities that arise from the spin-off itself.

The spin-off required the transfer of ADI's employees from Resideo's employment structure to ADI's new independent employment structure. This involves:

• Establishing new employment agreements or confirming existing terms for transferred employees
• Transferring employee benefit plan participation (health insurance, 401(k), equity compensation)
• Addressing unvested equity awards — employees who held Resideo stock options or restricted stock units at the time of the spin-off must have their awards adjusted to reflect the separation
• Complying with WARN Act notice requirements if any workforce reductions are associated with the separation

Directors and officers of both Resideo and ADI who served in those roles before the spin-off may face claims arising from pre-spin conduct. The SDA must address:

• Which company's D&O insurance covers pre-spin claims
• How indemnification obligations are allocated between the two companies for pre-spin conduct
• Whether a "tail" D&O policy is purchased to cover pre-spin claims after the spin-off

The Resideo–ADI spin-off is relevant for Turkish companies in two respects.

Turkish conglomerates considering separations: Several large Turkish conglomerates operate diversified businesses that might benefit from a separation into focused public companies. The Resideo–ADI transaction illustrates the legal and operational complexity of a spin-off — particularly the post-separation framework that governs the two companies' relationship for years after the distribution. Turkish companies considering a spin-off should plan for this complexity well in advance of the intended separation date.

Acquiring spin-off companies: Turkish companies that are considering acquisitions of recently spun-off U.S. companies should be aware of the Section 355(e) two-year restriction. An acquisition of a recently spun-off company within two years of the distribution date may trigger significant tax liability for the spun-off company's former parent — a liability that the acquisition agreement must address through representations, indemnification, and potentially a tax indemnity from the seller.
