Hi there,
It has no impact on your investment. What the company is doing is raising money through a Private Placement (so NOT a public secondary offering) of shares. In HUT's case, it is raising $77.5M by issuing 7.75M shares at $5.00 per share, and 7.75M Warrants which have an exercise price of $6.25 after two years.
This is a very normal process for a high growth company. Typically, small caps don't have ready access to debt and to grow the business they need to issue shares. A private placement is a good thing, because they it means they had parties lined up to buy their shares without having to go through a formal public offering. That usually means less costs for the company which is also why you will see the shares being offered at bigger discount to market price.
The net effect is share dilution, which means that there are more shares on the market and your ownership in the company effectively decreases. For illustration purposes. Say a company had 100 shares outstanding and you owned 10 shares. That means you own 10% of the company. If however, the company did a private placement for 10 shares, there are now 110 shares outstanding and your ownership drops to 9.1% of the company. Very basic example.
If the funds raised are to fund growth initiatives, this isn't necessarily a bad thing. If used properly, the money raised is put towards growth which in term generates more revenue/earnings for the company. Using the quick example above. Assume that the company has earnings of $1.00 per share, at the start - you effectively own 10cents of that. If they use the money raised by those other 10 shares to fund growth that leads to $1.20 per share, although your ownership of the company decreased, your earnings went up (10.91 cents). So this would be viewed as a good move by the company.
On the flip side, if the company continues to issue shares but grow slows, then you would have a lower percentage of earnings in which case, the moves would be questionable.
I hope this breaks it down in simple terms. Let me know if you have any other questions.
