As an owner of GLH I'd just urge a word of caution about extrapolating the cashflow out in the short term. Its invoicing is such that it presents as a seasonally cyclical business and Q1 is traditionally the lowest cash receipt quarter, by a considerable margin. I expect it to revert to cash burn mode in Q1 and would be happy if they managed to keep that to $500-800k. To some extent that may account for the muted market response to the recent 4C.
Overall though, I'm reasonably happy with how the business is progressing. While this isn't the highest quality business I've ever come across, I think you're being more than compensated for that in the valuation. It may be taking a little longer than hoped to achieve the outcomes management has promised, but progress is being made and you're starting to see that through the financials.
One thing I like about them is the quarterly commentary they give is meaningful. It's not just a ChatGPT rehashing of the previous quarter's commentary but is a warts and all account of issues and observations impacting the business over the previous three months. Not there yet but heading in the right direction.
