What is a constituent?

When searching for the definition of a constituent, it’s common to encounter two definitions:

  • (Noun) as used in politics — A resident of a district or member of a group represented by an elected official
  • (Adjective) Being a part or component of a whole

Most people hear the word “constituent” when discussing a political representative; it’s used frequently during election season. 

Another common use of the word involves a constituent company. A constituent company is one that’s listed on the S&P 500 or Dow Jones Industrial Average (DJIA). It’s common to refer to members of an index as components of the index; thus, “constituent companies” is a common phrase. 

There are two other important definitions that small business owners need to know, however.

The Business Definition of Constituent

There are two business situations where an entrepreneur might encounter a constituent. The constituent business definition encompasses two meanings:

  • Constituent company — a party to a merger
  • Constituent — a stakeholder in a business

What the term refers to will depend on a company’s current business stage. The following sections will explain these different stages and their benefits.

What are constituent companies in a merger?

A common growth strategy is the use of a merger. A merger happens when companies join together to form a larger organization. The merging companies are called “constituent companies” because they become parts of a new company, called the “surviving corporation.” Business owners involved in a merger need to remember that the term “constituent” only refers to the merging companies, never a parent company. This constituent meaning is important because each party to a merger has different legal requirements, including member voting requirements.

What is a business constituent?

When making a business decision, a business owner needs to consider all of their constituents. In this context, the definition of constituent means anyone affected by the project. It’s popular to think of the business as a “representative” of the stakeholders (see the constituent definition above). Like a politician, a business exists to meet the needs of its stakeholders. 

Accordingly, when business planning, entrepreneurs should consider the impact of their business on their:

  • Project team
  • Employees
  • Customers
  • Suppliers
  • Investors
  • Members of the community where they conduct business
  • Environment
  • Overall business goals

When weighing the needs of the constituents, business owners will want to ponder the advantages and disadvantages a project poses for their constituents. Most business owners can face liability if they don’t do what’s in the best interest of their company. It’s wise for business owners to cite constituent advantages and disadvantages in their business plan as evidence to support their executive decisions.

Summary

The constituent definition includes one of four meanings: (1) the people represented in a political district, (2) a company represented on a major stock index, (3) a company that’s a party to a merger, or (4) a project stakeholder. In a business context, the meaning of constituent will depend on the company’s stage of business.
