Backward Integration

What Is Backward Integration?

Backward integration is a strategy in which a company expands upstream, taking over the businesses that supply the materials, components, or services it needs. Instead of buying those inputs from outside vendors, the company brings them in-house, either by acquiring a supplier or by building the capability itself. It is one form of vertical integration, the broader approach of owning more than one stage of production.

The word "backward" refers to the direction along the supply chain. A manufacturer sits between raw material producers and final customers. Moving toward the earlier stages is backward, while moving toward customers is forward integration.

How It Works

A company pursuing backward integration typically either purchases an existing supplier through an acquisition or starts its own operation to produce the input. In both cases, the company takes on responsibility for the quality, timing, and cost of inputs it previously managed through contracts.

For example, a furniture maker that has always bought lumber from independent sawmills might acquire a sawmill. The margin the sawmill once earned on sales to the furniture maker is then kept inside the group.

Advantages and Disadvantages

Backward integration can secure input supply, give the company more control over quality, and capture margin previously paid to suppliers. It also reduces dependence on a few outside vendors.

The strategy carries real costs. Building or acquiring a supplier requires significant capital and management attention, and the company may take on expertise it lacks. If cheaper inputs later become available on the open market, the company may still be committed to its own higher-cost operation. Large vertical combinations can also attract review under antitrust law.

Why It Matters to Investors

Backward integration changes a company's risk profile and cost structure. An annual report can show whether a company owns key suppliers and how its margins compare with rivals that buy inputs on the open market. Analysts often weigh those differences against the capital invested. Investors may also consider how much of the company's future growth depends on operations it must now fund and manage.
