It's simple maths. Fundraising dilutes a share. So if the company has one share worth Β£100, and they need another Β£100, they arguably need to release one more share onto the market. If they can get buyers, they can sell this at any price, but market dynamics would suggest they would reasonably price this at the same value as the existing share. However, they may only sell at Β£80, or indeed Β£120. In reality, although the company will have more cash after the raise, markets tend to keep similar market caps after, so the share price can fall unless they raise at a premium. In the example, likely to be Β£50, to maintain the Β£100 Mcap, or a 50% drop in existing share price.
In either case it can dramatically impact the share price. At lower share values, the company will need to release more stock to get the same amount in funds. This means that they will have to dilute a far higher proportion of the company to get the same return, thus heavily impacting price, thus pushing down the raising value.... vicious cycle. If so, they may not be able to complete a raise, and then would run out of cash, and go bust.
But that's the process, though not fully accurate, gives you a basic overview. Hopefully helps to point out it's not actually the share price that important, it's the amount needed to raise in relation to floated shares and price combined.
Others may have a more accurate view.
