Primark is owned by the British food processing company Associated British Foods (ABF). In its 2019 annual report, ABF reported that its retail subsidiary had generated a revenue worldwide of more than seven billion British pounds that year, but the company's growth rate in sales over the past years has been somewhat slow. Primark’s performance in its primary market, the UK, has also seen consistent improvement, with stores in the country reaching a net worth of over one billion pounds in 2019. This represented an increase of almost 250 million pounds on the company’s net worth in 2016.
As Primark’s net worth has increased so too has its share of the UK apparel market. In 2007, the retailer had a market share of around 4.1 percent and this figure is estimated to have risen to seven percent by 2018. As a result, the fashion brand has almost equaled the share of the market held by Marks & Spencer, the country’s top clothing retailer, whose market share has fallen by around two percent over the last ten years. Primark’s share of the value clothing market is much higher, ranking just behind Asda, with a market share of 13.5 percent.
Among the clothing products offered by Primark, women's wear is the most popular category, with 11.9 million consumers in 2019. In comparison, men’s wear and children’s clothes were purchased by a respective 10.9 and 7.6 people that year.
