If you’re looking for a treasure trove of IPO data, check out these stats from Professor Jay Ritter at the University of Florida. Maybe some of you are already familiar with his work – as his data informs a lot of financial reporting – but I had not done a deep dive.

This particular set looks at info from initial public offerings from 1980 to 2024 – 44 years! – including the type of backing the companies had at the time they went public, age and profitability, and first-day and three-year returns by lead underwriter. We all hear the common refrains that the volume of IPOs has been lower lately and that companies have been waiting longer to go public – but seeing the data puts things in perspective:

1. The median number of IPOs from 1980-2019 was 158 – well above the 72 IPOs last year, 54 in 2023, and 38 in 2022.

2. The average age of companies going public was 9.5 years from 1980-2019, but it’s been ticking up the past several years – from 8 in 2022, to 10 in 2023, to 14 years in 2024.

3. For tech IPOs, valuations at IPO are higher – and IPO profitability is lower. For example, in 2024, the median price-to-sales ratio was about $9-$11, compared to about $3-$4 in 1980. But that’s nothing compared to the dot-com bubble, which reached a height of $49.5!
