South Australian Business Index 2021

InDaily’s ranking of the state’s top 100 companies by market capitalisation and revenue covers the 2020-21 financial year and includes more volatility than usual, due to the COVID-19 pandemic.

The list, compiled for InDaily by Adelaide financial services firm Taylor Collison, is the state’s most definitive guide to our top companies (scroll to the bottom of the page for eligibility criteria).

The countdown began on Monday and will continue all week – with the top 20 and full list revealed in InDaily tomorrow (see the list so far here). InDaily will also announce winners of individual awards tomorrow – a “rising star” award for the company that has jumped furthest up the rankings, a revenue growth award, and another recognising the best new entrant to the Index.

Companies with product offerings that lined up with sectors spurred on by pandemic spending fared well in the 40-21 section, from computing to beauty and beer.

Leader Computers jumped eight spots in the index to 29 after a $100 million increase in revenues to $479 million in 2020-21.

This jump led to an increase in Leaders’ market capitalisation to $335 million, which was no doubt boosted by the IT boom as businesses scrambled to set up and maintain work from home arrangements throughout the pandemic.

Supermarkets and alcohol producers for the domestic market have also generally done well during the pandemic and SA icons Coopers Brewery and Drakes Supermarkets are no exception.

Regency Park-based Coopers is the largest Australian-owned brewery.

After recovering from keg losses in the early part of the pandemic in 2020, the family-owned brewery grew its revenues in 2021 and maintained its position at No. 22 in the index with a market cap of $420 million.

“For six generations, or 159 years, the Coopers family has brewed the renowned pale and sparkling ale, which is enjoyed around the world. A success story for doubtless, many generations to come,” Rorrison said.

Adelaide-based Drakes Supermarkets is the largest independent grocery retailer in Australia, operating more than 50 stores in South Australia and Queensland.

The company now has an annual turnover in excess of $1 billion and employs over 5500 staff nationally, helping it maintain its ranking of No.23 in this year’s list.

Among the biggest movers in the list was health software platform provider Alcidion Group jumped 20 places to No. 27 while structural steel manufacturing and fabrication company Ahrens Group fell eight spots to No. 36 despite increasing revenues by 15 per cent to $460 million in 2020-21.
