The full list, compiled by Adelaide financial services company Taylor Collison, will be revealed in full at a lunch at the Adelaide Convention Centre next week (September 20), featuring Premier Steven Marshall as the keynote speaker.

However, InDaily will start revealing the companies on the list later this week.

To be eligible for inclusion in the list companies must:

• Be a South Australian entity with an Adelaide ownership register, or be a South Australian operated entity;
• Be a company founded and majority (50.01 per cent plus) owned by South Australians.

Companies owned in part or whole by government, government agencies and organisations, and registered charities are not eligible for consideration.

Check InDaily over the next week for more information about the make-up of the list, including industry sectors, but we can reveal today that the overall market capitalisation of the state’s top 100 companies has boomed in 2017-18.

Taylor Collison’s analysis shows market cap has increased from $37.5 billion in the 2017 Index to just under $50 billion this year. And last year’s result was a five per cent increase on the year before.

The sharp increase in value can be put down to a continuing rebound in the resources sector. South Australia’s largest company, Santos, has returned to profit, fresh from staving off a takeover bid.

It’s also been a strong year for Beach Energy and miner OZMinerals. The construction and engineering sector has also had a strong year, with many companies showing revenue growth of 50 per cent year-on-year.

Now in its fourth year, the Index also recognises fast-moving and up and coming companies in SA.

Additional prizes to be announced at next week’s event include the fastest growing company on the list, the rising star (for the company that moves the highest number of places up the ranking), and the best new entrant, for a company that hasn’t previously been in the top 100.
