Why So Many Giant Companies Are Breaking Themselves Apart
In June 2026 Honeywell splits into two companies, the latest in a wave of giant conglomerates breaking themselves apart. The logic behind it is a core idea in corporate strategy, the conglomerate discount, and the belief that the parts are worth more than the whole.
The Era of the Giant Conglomerate Is Ending
On June 29, 2026, Honeywell, one of the last great American industrial conglomerates, splits into two separate public companies, Honeywell Aerospace and Honeywell Technologies, after first spinning off its advanced materials business in late 2025. It is one of the largest corporate breakups in recent memory, and it is not an isolated event. General Electric, once the most admired conglomerate in the world, finished splitting into three companies in 2024. Warner Bros. Discovery has announced its own separation. The age of the sprawling, do-everything company is giving way to something sharper and more focused, and the reason comes down to a single idea in corporate strategy.
The Conglomerate Discount
A conglomerate is a company that owns several unrelated businesses under one roof. For decades the pitch was that diversification smoothed out the bumps, a strong aerospace year covering a weak chemicals year, and that a talented central team could allocate capital across the whole portfolio. The problem is that the market often values the combined company at less than its parts would be worth on their own. That gap is called the conglomerate discount, and it is real money. In Honeywell's case, analysts estimate the standalone businesses could command operating multiples 25 to 30 percent higher than the conglomerate carried as one company.
Why the Discount Exists
Several forces create it. Investors who want pure exposure to aerospace do not want it diluted by an unrelated automation business, so they pay less for the bundle. Analysts struggle to cover a company that spans five industries, and complexity that is hard to understand tends to trade at a discount. Capital can get trapped, with cash from a strong division quietly funding a weak one that should have been sold or fixed. And accountability blurs, because a struggling unit can hide inside a big, diversified income statement.
The market's message is blunt. It will often pay more for a clean, focused business it can understand than for a complicated one it cannot, even when the focused business is smaller. Clarity itself has value, and conglomerates spent years discovering how much.
The GE Proof
The clearest evidence is General Electric. When it split into GE Aerospace, GE Vernova, and GE HealthCare, the combined market value of the three pieces grew to roughly four times what the single company had been worth at its 2022 low. Same assets, same people, same products, and dramatically more value, simply from letting each business stand on its own and be judged on its own merits. That result is exactly what every breakup since has been chasing.
The Role of Activist Investors
Many of these breakups are not management's idea. They are pushed by activist investors who buy a stake, run the sum-of-the-parts math, and campaign publicly for a split to unlock the trapped value. Honeywell's move followed pressure of exactly this kind. Activists have turned the conglomerate discount into a repeatable playbook: find a sprawling company trading below the value of its parts, take a position, and agitate for separation until the board gives in.
The Case for Staying Together
Breakups are not free, and the other side deserves a hearing. Splitting up means duplicating corporate functions, finance, legal, and human resources, across the new companies, which raises costs. It removes the internal capital market that let a parent fund promising projects without going to outside investors. And a smaller, focused company has nowhere to hide during a downturn in its single industry, because diversification really does reduce volatility. The honest question is whether the discount the market applies is bigger than the benefit the diversification provides, and investors are increasingly deciding that it is.
Why It Matters for the Role
A breakup is one of the purest exercises in corporate strategy and valuation there is. Doing the sum-of-the-parts analysis, valuing each business on the multiple its pure-play peers command, and comparing that to the conglomerate's actual price, is exactly the kind of work that decides whether a company is worth more whole or in pieces. It is strategy and finance meeting in a single high-stakes question.
