Pubmatic (positive) analysis

To close the loop on this one seeing that I wrote them up.

I sold Pubmatic yesterday and used the proceeds to buy more SentinelOne.

Why?

  1. SaaS valuations have been pummelled and offer good, arguably great value and very high predictability, much more predictability than ad-tech.
  2. I know SaaS very well - much better than I will ever understand ad-tech (I’m part-owner of a small SaaS outfit), and given the current blood on the proverbial streets of my portfolio, I want to be invested in stuff I really understand.
  3. Pubmatic’s current hyper-growth is driven by very high NRR. Their new customer additions have not been a driver - very limited land, it’s all been expand - Q3 Revenue growth was 54% and NRR was 157%, meaning that contribution from new customers must have been negligible/negative. Also, NRR will drop off due to the company being seasonal. This is key and I did not see this until I critically reviewed all my holdings in light of the current carnage - a bit careless of me there…
  4. CTV will no doubt contribute nicely in future, but it is still very small and will take time so can’t be the main underpinning of the thesis.
  5. If I’m being honest, a key part of the thesis for owning PUBM for me was that I was hoping on a re-rating of Ad-tech generally, after a dismal year. In the current environment I don’t want to base anything on hope.

Thanks for your thoughts AIC123.
