Will:

Just firstly, in terms of the decision to go down this SPAC route, and perhaps not a direct listing yourselves, or go down the IPO route, why was it that you decided to partner with the SPAC to get this done?

Jane Hunter:

Yeah, thanks Will, and thanks for having me. Look, the SPAC route really allows us to access a very large source of capital, and help fund our growth and compete globally, which is really important because a number of our competitors already done that. So it’s particularly important for us to keep our market share, and grow our market share.

We already have 20% of European market, 58% of North America, and 10% of Asia Pacific. So we want to keep that, and grow that even further. And that does mean this ability to grow our sales, our factory operations, and continue to compete with our competitors.

Will:

Now you flagged as well that, some of this money is potentially to build out your manufacturing and all of that, like in terms of what that manufacturing then means, because I know that here in Australia, and especially in the United States as well, there is a lot of range anxiety when it does come to EVs. So do you have like a ballpark figure, in the sense of how many of your actual products in terms of these fast charging units, you would need per kilometer, for example, to really deal with that kind of an issue?

Jane Hunter:

Yeah. In a country like Australia, the way that we see it is that, you need to have 50 kilowatt charges in the Metro areas, and that’s really important, that gives you a small top up, you can keep going and get on with your day. On the large highway sites, you need a 350 kilowatt charger, and that gives you 350 kilometres of range in 10 minutes.

So for 50 kilowatt, you get 50 kilometres of range in that 10 minutes. And so we see them as two different markets, and then it’s necessary to have those dotted along the highways, so that every 350 or 250 kilometres, you can just stop in, and get the range that you need to get on with your day.

Speaker 3:

Jane, great to see you, and appreciate your time. Hope you keeping safe wherever you are. I mean for investors out there, one sort of curious thing they’re trying to get a handle on is, why this SPAC deal did not include what is known as a PIPE, which is a private investment in public equity.

Essentially, if you’d done a private placement, would it mean that a bunch of investors could have gotten in at a very affordable level, and made a bunch of money. In this case, it didn’t happen. Why?

Jane Hunter:

Look, we did speak to investors. That was something that we certainly considered, but we didn’t need a PIPE, because Decarbonization is more than $400 million back. And our shareholder group agreed to a minimum cash closing, of close to 200 million, which significantly reduces redemption risk.

Also, our revenue has grown at a compound annual growth rate, CAGR, at 56%, since 2016, as we expand our presence in those major markets, where we have a significant market share, such as the US and Europe, and this revenue growth just helps us to reduce our reliance upon new funds, to implement our growth strategy. So we didn’t need a PIPE.
