What is this Substack?

Analyzing Good Businesses (or “AGB”) is a research newsletter covering the history and business model quality of a universe of “good” companies. High returns on incremental capital + long runway for reinvestment is the rubric that these companies are measured by.

AGB aims to analyze why these businesses are “good” and how they sustain that quality over a long period of time.


How can subscribers leverage AGB?

There are three main value-adds from this newsletter.

1. Selection of the companies. Because AGB only focuses on “good” businesses, there are specific lessons to be learned when understanding these businesses.

2. Deep understanding through the AGB framework. Instead of the what, we’d argue that it’s more important to understand the why and the how of “good” businesses.

3. Time saving. Write-ups are intended to the give the reader a strong head start in understanding the history and business models of the companies we cover. The reader can then leverage that to further deepen their knowledge about specifics tailored to their own professional or personal requirements.


What do you get for the different subscription tiers?

This is a reader supported newsletter. We don’t participate in sponsorships or ads.

Paid subscribers get access to (1) New AGB & Update write-ups with models and (2) the 2023-2025 archive.

Prime supporters get access to All 70+ write-ups with models (2020-2022 included).

Free subscribers get access to the No Paywall tab and the first section preview of new write-ups. Content under this tab will rotate over time, so it’s worth staying a free subscriber.

The monthly plan price is $20 and the annual plan price is $100. I’ve priced the plans to highly encourage paid subscribers to go with the annual plan. For those that want access to the entire archive, the prime supporter annual plan price is $250.

Thank you everyone for your continued support!
