Each year, the Roaring Twenties awards recognize the 20 fastest-growing large companies and 20 fastest-growing small companies in the state. Those winners have been invited to a statewide event in Columbia honoring them, and counting down to the top company in each category.

Finalists were chosen and ranked according to growth and revenue. Company size was determined by gross revenue — small is $10 million or less; large is more than $10 million. Small companies must have had revenues of at least $500,000 each year for three years.
