The exchange allows trades with a given settlement date; only on that date will money and shares change hands. If I sell on a T+2, the shares need to be delivered to the buyer on the second day following the sale, and the buyer must pay for them on that day. Settlement periods are part of the bargain: you can do T+10, T+20 etc. although most retail now is T+2.
The warrants are convertible to shares. Assuming no conditions to conversion, they can be converted on demand, on payment of the fee per share (eg, 1.85p). The warrants are presented and the company responds by issuing new shares. That is exercising the warrants, so that's already happened. The issue is unconditional so the warrantholder can rely on getting them on admission date. All that's needed is to combine settlement periods and unconditional shares: a warrantholder can sell the shares in advance of getting them ("forward-selling") with a settlement period ending when the shares are admitted, at which point they're handed over to the buyer. In fact, they can be sold in advance of exercising the warrants, and hence a public announcement, with a long-enough settlement period.
