The estimated Wesfarmers net worth/market cap is $82.71 billion as of 18 September 2026, according to the Australian Securities Exchange (ASX). Its revenue according to the Wesfarmers’ 2026 Annual Report is $47.3 billion.

Company overview

Wesfarmers was founded in 1914 as a farmers’ cooperative. The company was originally established to provide goods and services to the state’s rural communities.

Over the decades, Wesfarmers expanded beyond its agricultural roots through acquisitions, investments and diversification, eventually becoming one of Australia’s largest publicly listed companies.

It converted from a cooperative into a public company in 1984 and was listed on the Australian Securities Exchange on 15 November that year.

Today, Wesfarmers has more than 118,000 team members and more than 480,000 shareholders. Its stated primary objective is to deliver satisfactory long-term returns to shareholders.

The company has developed a broad portfolio covering retail, industrial and safety products, chemicals and fertilisers, energy, healthcare and investments.

Its best-known businesses include Bunnings, Australia and New Zealand’s home-improvement and outdoor-living retailer, Kmart Australia and New Zealand, Target Australia, Officeworks, Wesfarmers Health, and Wesfarmers Chemicals, Energy & Fertilisers (WesCEF).

The group also has interests in lithium through its Covalent Lithium joint venture and operates or invests in various other businesses and assets.

A major milestone in Wesfarmers’ expansion came with its acquisition of Bunnings, which began with a 10 per cent investment in 1987 and culminated in full ownership in 1994.

Another significant achievement was its $22 billion acquisition of Coles Group in 2007, described at the time as the largest takeover in Australian corporate history. Wesfarmers subsequently separated Coles through a demerger in 2018 and ultimately sold its remaining stake in 2023.

The company has also expanded into healthcare, acquiring Australian Pharmaceutical Industries for $740 million in 2022 and later adding businesses such as InstantScripts and Pharmacy 4 Less to its healthcare operations.

Wesfarmers has also recorded notable milestones in its industrial and resources businesses. In 1979, it acquired a controlling interest in CSBP, a chemicals and fertiliser manufacturer, and completed full ownership in 1986.

Its portfolio has since grown to include chemical, fertiliser and gas operations as well as lithium development.

At the same time, Wesfarmers has periodically sold or separated businesses when they no longer fit its long-term portfolio strategy, including its coal interests, insurance operations and Coles.

In financial terms, Wesfarmers is one of Australia’s largest companies by revenue. In the 2025 financial year, the group reported A$45.7 billion in revenue, while its annual report recorded A$2.926 billion in reported net profit after tax.

The company continues to invest in its retail, healthcare, industrial and lithium-related businesses while pursuing productivity improvements and other strategic initiatives. Currently, it is under the leadership of Rob Scott.

For the 2025 financial year, Wesfarmers also reported progress in renewable electricity use, with Bunnings and Officeworks having achieved their target of using 100 per cent renewable electricity by the end of 2025, while Kmart Group was working toward the same target.

The company also reported that Aboriginal and Torres Strait Islander employment remained above parity among its Australian team members.

Its sustainability reporting covers areas including team member safety, diversity and inclusion, Indigenous reconciliation, suppliers, customers, communities and environmental performance.
