A conglomerate is a corporation made up of several distinct businesses, often in unrelated industries, under the control of one parent company that holds a controlling stake in each. The businesses run their own operations, but their leaders report to the parent’s senior management, which decides how capital is spread across the group. In business usage, “conglomerate” means diversification across different lines of business. A large company that grows only within one industry is usually just a large company.

How a Conglomerate Is Structured

The basic conglomerate structure has two layers. At the top sits the parent company, sometimes a pure holding company that makes nothing itself. Below it are subsidiaries, each a separate company with its own management team, customers and accounting. A subsidiary that makes industrial equipment and one that sells insurance may share an owner and nothing else.

Control does not require owning 100% of a business. A controlling stake, usually a majority of the voting shares, lets the parent appoint the board and direct strategy. Many conglomerates also hold minority stakes in other companies. Those stakes are investments rather than controlled subsidiaries.

The parent’s main job is capital allocation. It collects cash generated by mature businesses and decides whether to reinvest it in those businesses, fund growth elsewhere in the group, buy new companies or return money to shareholders.

How Conglomerates Are Formed

Conglomerates come together, a process called conglomeration, in three main ways:

• Acquisitions. One company buys another in a different industry. A large target may be merged into the buyer rather than kept as a subsidiary, combining assets and personnel into one entity. The Walt Disney Company’s 1995 deal for the American Broadcasting Company (ABC) is a well-known conglomerate merger.
• Restructuring. A company reorganizes and sometimes creates a new parent to own its businesses. In 2015 Google restructured so that a new parent, Alphabet, sat above Google, which became one subsidiary among several.
• Extension. A family business or a single-industry company moves into new sectors. Berkshire Hathaway began as two 19th-century Massachusetts cotton mills that merged in 1955. Warren Buffett took control in 1965 and turned it into a holding company that invests in other businesses instead of making textiles.

Worked Example: The Conglomerate Discount

Analysts often value a conglomerate with a sum-of-the-parts approach. They estimate what each business would be worth as a stand-alone company, add the figures together and compare the total to what the market pays for the whole group.

Hypothetical example. A parent, Example Holdings, owns three subsidiaries. Analysts estimate their stand-alone values as follows:

Suppose the market values Example Holdings as a whole, measured on the same basis (for instance enterprise value, which includes debt), at $8.8 billion. The discount is:

Conglomerate discount = (Sum of the parts − Value of the whole) ÷ Sum of the parts = ($10.0B − $8.8B) ÷ $10.0B = 12%

A 12% discount means investors pay less for the bundle than they would for the same businesses traded separately. The result depends heavily on the stand-alone estimates. Those are often built with a discounted cash flow model or peer multiples, and different assumptions can turn a discount into a premium. Academic research on diversified firms has estimated discounts of up to roughly 15%.

Why Companies Build Conglomerates

• Risk spreading. A weak year in one business can be offset by stronger results in another. Cyclical businesses, whose sales rise and fall with the economy, can be paired with noncyclical or countercyclical ones.
• Shared costs. Subsidiaries may share inputs, purchasing, back-office functions or distribution, which can lower costs for the group.
• Internal capital markets. The parent can move cash from businesses that generate it to businesses that need it, sometimes faster and more cheaply than outside funding. Whether that beats raising money externally depends on the group’s cost of capital and on how well the parent picks projects.
• Takeover defense. A large, diversified parent can be harder and more expensive for a hostile buyer to acquire.

Limitations of a Conglomerate

• Valuation discount. Markets often value the whole below the sum of its parts.
• Management strain. A group spanning many unrelated industries can become too complex for one leadership team to oversee well. Acquired companies sometimes fail to improve under new ownership, and if the parent mismanages them, they can drag down the whole group.
• Opacity. Mixed segments make the group’s financial health harder for investors, analysts and regulators to assess. Measures such as return on equity blend very different businesses into one number.
• Overhead. Some economists argue that sprawling groups become costly to run and erode shareholder value.

When a conglomerate struggles, the usual remedy is to shrink. It sells businesses (divestiture) or spins them off as independent public companies, then refocuses on a smaller set of core holdings.

The 1960s Conglomerate Boom

Conglomerates multiplied in the United States during the 1960s. Interest rates were low, so borrowing to buy companies was cheap. As long as an acquired company’s profits exceeded the interest on the debt used to buy it, the parent earned a return. Promises of synergy across companies, products and markets helped justify a wave of mergers.

The trend peaked in 1968, according to the history “The Go-Go Years.” Roughly 4,500 mergers took place that year, and 10 of the country’s 200 largest companies were conglomerates. The boom faded by around 1980 as interest rates rose with inflation and debt-funded buying became harder to justify. Many groups assembled in that era were later broken up.

Examples of Conglomerates

Conglomerates appear in many fields, including manufacturing, media and food. A media group might start with newspapers and add television, radio and book publishing. A food company might begin with potato chips and add a soda maker and other brands.

• LVMH (Moët Hennessy Louis Vuitton). It traces back to Louis Vuitton’s luggage and leather goods business, founded in 1854. LVMH was formed when Vuitton merged with the wine and spirits company Moët Hennessy. The group describes itself as home to about 75 brands, or “maisons,” across six sectors, including jewelry (Tiffany & Co.), cosmetics, publishing and fashion (Fendi).
• Berkshire Hathaway. Its businesses have ranged from insurance and real estate to manufacturing. The parent handles capital allocation and gives subsidiary managers wide discretion. Berkshire owns majority stakes in dozens of companies and minority positions in many more.

Conglomerates Outside the United States

• Keiretsu (Japan). Companies hold small stakes in one another and are often grouped around a core bank. The cross-holdings can protect members from sharp market swings and hostile takeovers. Mitsubishi is a commonly cited example.
• Chaebol (South Korea). These are family-controlled groups in which leadership typically passes within the founding family, which often has more control than outside shareholders or the board. Samsung, Hyundai and LG are chaebol.
• Konzern (Germany). The term refers to a group of legally separate companies under unified management. A Konzern can be a conglomerate if its businesses span unrelated industries, but it can also operate within a single sector.

Conglomerate vs. Related Terms

• Holding company. A holding company owns shares in other companies. Many conglomerates are run through one, but a holding company can own businesses in a single industry.
• Group of companies. This is a general term for related companies under common control, without any implication of diversification.
• Multinational corporation (MNC). An MNC operates in more than one country through subsidiaries, branches or other foreign holdings, and it may stay in one industry.
• Multinational conglomerate. This is a conglomerate that owns businesses in at least one country other than its home country.

The Bottom Line

Conglomerates matter most to investors and analysts judging whether a diversified group is worth more together or apart. Spreading risk and moving cash internally can help, but markets often value the whole below the sum of its parts, and mixed segments make results harder to read. When a group struggles, selling or spinning off businesses and refocusing on core holdings is the usual remedy.
