Here's 2 links...... One article from Leafly that speaks to some of the red flags. And another shouting them out. I consider Leafly a competitor of sorts so even though there is good info here you might want to consider the source in terms of presentment.
The Leafly article is around 7 months old. Based on the article I'd guess that the folks who are waiting for the formal IPO, expecting lower stock prices, may have a point based on "current" valuation.
One thing I definitely take with a grain of salt here is the statement that the Pre-IPO share price of $11 is 10% below the expected IPO price. I would not buy any stock based on this statement. The "expected" IPO price will change multiple times as they start to gauge how many will subscribe to the IPO and for how many shares/how much. They will likely manage the IPO shares to try and cause a pop on day 1 BUT that pop-price could be lower than $11 and the pop is never guaranteed.
One way to gauge this is by who HT hired to manage the IPO. The larger reputable companies will not get involved with shady/slick offerings. The other consideration is whether the intention by new management is to go public to grow the company or dump/sell it at a huge gain after selling as much stock as possible. Happens all the time......
The fact remains that the potential is there for HT to grow and be a good investment if that's the intention.
