A company does not necessarily need to invent an entirely new product in order to grow. Sometimes growth lies in its ability to make an existing product relevant to a new audience or connect it to a different interest.

This idea is clearly visible in the Lego model. The basic plastic brick has not changed radically, but what can be built with it is now connected to football, Formula One, Star Wars, films, plants, and even sports figures.

During the first half of 2026, the company’s revenue rose by approximately 21% to DKK 41.9 billion, while net profit increased by an even greater 32% to DKK 8.6 billion.

But what do these figures tell us about how companies grow?

One Product… But Multiple Markets

One of the simplest ways companies grow is by expanding what is known as the addressable market.

If Lego is viewed solely as a children’s toy, the size of its market is tied to the number of children and families willing to buy building toys.

But when there is one product for football fans, another for Formula One followers, sets linked to films and television series, and botanical designs intended for display at home, the company is no longer competing only in the children’s toy market.

It is also competing for a share of adults’ spending on hobbies, entertainment, and collectibles.

Here, the core product changes less than the reason consumers have for buying it.

Why Do Companies Care About Adult Customers?

One of the most notable shifts in the toy market in recent years has been the rise of a group sometimes referred to as Kidults—adults who buy toys and collectibles for themselves.

In the British market, for example, this group now accounts for approximately one pound out of every three pounds spent on toys.

Economically, the importance of this group does not come solely from the increase in the number of buyers.

Adult consumers generally have greater purchasing power than children and may be more willing to pay substantial amounts for a product associated with a character, sport, or brand they love.

That is why some Lego sets associated with players such as Cristiano Ronaldo and Lionel Messi sell for more than £150.

Here, the toy shifts from being a simple product to a collectible and displayable entertainment product.

Why Are Profits Growing Faster Than Sales?

There is another figure worth examining.

Revenue rose 21%, while net profit increased by 32%.

When profits grow faster than revenue, this may indicate that the company has become better at converting each additional unit of sales into profit.

This is where the concept of operating leverage comes in.

Some corporate costs are relatively fixed, such as factories, systems, administration, and development. When sales rise significantly, some of these costs do not need to increase at the same rate.

As a result, an increase in sales can translate into even stronger profit growth.

By a simple calculation, Lego’s net profit margin in the first half of the year was approximately 20.5%, meaning the company generated more than DKK 20 in net profit for every DKK 100 of revenue.

What Role Do Brands and Partnerships Play?

When Lego launches a set linked to the World Cup or Star Wars, it is not merely selling plastic bricks.

It is benefiting from pre-existing demand surrounding another brand, event, or character.

A football fan who was not originally interested in Lego may become a consumer after seeing a product linked to their favorite player. The same applies to audiences for films, cars, or television series.

This strategy reduces the company’s reliance on a single interest and spreads its product portfolio across different consumer segments.

This is also reflected in the launch of approximately 330 new products during the first half of 2026.

But having a large number of products is not the goal in itself; the goal is to increase the number of reasons consumers have to enter a store and find a product that aligns with their interests.

Does Growth Come Without a Cost?

Not always.

Lego itself expects some costs to rise during the second half of the year, whether for raw materials, transportation, or energy.

This illustrates the difference between revenue growth and the quality of growth.

A company may sell more, but the more important financial question is: can it maintain its margins when production and transportation costs rise?

Therefore, when analyzing a company, it is not enough to look only at the sales growth rate; we must compare revenue growth with profit growth, profit margins, and operating costs.

From Children’s Toy to Platform for Interests

Lego’s story illustrates a broader idea in economics and business: companies do not grow only because they sell more units of the same product, but because they can expand what that product means to consumers.

A child may see Lego as a building toy, while someone else sees it as a model of their favorite team, a third person sees it as a decorative piece, and a fourth buys it because it is connected to a film or car they love.

When a company can sell the same product for different reasons to age groups and audiences with diverse interests, it does not merely increase sales; it expands the market in which it can compete.

That is why the most important message behind Lego’s 21% increase in sales is not that people bought more toys, but that the company succeeded in making a decades-old product relevant to more people and more occasions and interests.
