A maker of sustainable plastic strikes a SPAC deal

Origin Materials, a start-up that makes plastic made from sawdust, announced today that it is going public by merging with Artius Acquisition, a blank-check company, in a $1.8 billion deal. DealBook spoke with key executives about what the deal means.

Origin Materials considers itself as a carbon-negative company. Its pitch: Not only does it replace petroleum-based plastics, the start-up says that its production process actually removes atmospheric carbon. “We’re at a real corporate tipping point on the need to reduce their carbon footprint,” said Rich Riley, the company’s co-C.E.O. “We can help those companies decarbonize.”

A desire for speedy capital brought it to SPAC land. Origin Materials was seeking money to expand its production, Mr. Riley said. Bankers directed it to Artius, a $725 million SPAC founded last year by Charles Drucker, the former Worldpay C.E.O., and Boon Sim, the former global head of M.&A. at Credit Suisse. “This is not a niche product,” Mr. Sim said. “This could be the Tesla of materials companies.”

A gauntlet of due diligence. Artius spent three months going through Origin Materials’ books and facilities, and then about 60 prospective investors questioned the team in a fund-raising effort. Ultimately, Artius and Origin Materials raised $200 million on top of the SPAC funds, which people briefed on the matter said was oversubscribed.

Origin Materials Goes Public

CORPORATE PARTICIPANTS

John Bissell - Co-CEO and Cofounder of Origin Materials

PRESENTATION

Andrew Ross Sorkin

Welcome back to Squawk Box. We’ve got some breaking news in the SPAC world, Origin Materials going public via Special Purpose Acquisition Company, Atrius Capital. Origin is a carbon negative materials company that turns the carbon from fuel sources into other products while capturing carbon from them in the process. Partners for the company include PepsiCo and Nestle. The deal values Origin at roughly $1.8 billion. And joining us right now is John Bissell. He’s the co-CEO and co-founder of origin materials. Good morning to you. Congratulations on this moment in your journey. Tell us about the decision to go public via SPAC. And in truth, tell us were you planning to go public otherwise?

John Bissell

Sure. It’s a good question. So you know, for us going public via SPAC was really, of course, there’s the speed and certainty that you get from SPACs that everybody sort of talks about. But I think there were two other components that were really important in our decision there. One was, you know, first Artius (ph), you know, they’re exceptional ambassadors. They did an extraordinary amount of diligence. And that was really, you know, helpful to see that level of sophistication in the diligence process.

And then I think being able to talk to public equity investors, you know, 50 or 60, of the world’s most sophisticated investors through the diligence process in the marketing process, I think was really useful. So that was a big driver of it, you know, a lot more diligence from that perspective than we’d see with a typical IPO process. And then I think the second component is the proceeds to the company for the execution of our business plan are actually larger with, or I should say, are typically larger with SPACs than they are with IPOs. And so that was important to us as well, lets us execute on what we’re doing.

Andrew Ross Sorkin

So let--walk us through this company for those who are uninitiated in terms of what the opportunity set is and what you plan to use this money for.

John Bissell

Sure. So our mission is to enable the world’s transition to sustainable materials. And our technology platform for producing sustainable materials makes it possible for companies to hit their net zero commitments. That’s the key, we’re starting with PET, which means our technology is drop-in ready. It replaces the fossil resources used to make a variety of everyday products.

And the feedstock for a process comes from abundant nonfood sources. So timber, construction waste, paper waste, other wood residues. That’s the kind of stuff we’re using to feed our process. And the feedstock used in our technology enables us to be cost competitive with petroleum based materials. So as you mentioned, we partnered with Danone, Nestle, and Pepsi to form the Natural Bottle Alliance that’s focused on advancing our shared goal of creating beverage containers would significantly reduce carbon footprint. But that’s not the only material we’re making.

We have $1 trillion market opportunity to revolutionize their materials for a wide range of end products, including clothing, packaging, you know, car parts, tires, more. And then to bring it back to the transaction, specifically, this will fully fund origin until EBITDA and free cash flow positive, which lets us effectively scale and start commercial production. And that scale lets us satisfy signed customer contracts of $1 billion across a whole wide range of industries.

Andrew Ross Sorkin

So I was looking through some of the numbers. Help us just understand what it takes—what revenue looks like right now, what it takes to get to profitability. And it does look, hopefully, if it all works, like a hockey stick in a good way. But what about the challenges ahead?

John Bissell

Yeah, so we’re building what we call our Origin One plant right now. That’s under construction. And that plant, really, we see as a, you know, of course, it’s using our technology, but it’s a market development plant in a lot of ways for things beyond the drop in products, PET that we’re starting with. And then with this funding, we’ll actually start construction on what we think is Origin Two, which is our first fully commercial scale plant. So we see revenue coming online from Origin One and ’23, but really significant revenue is going to come from this plant, we’re starting now, which will come online and ‘25.

Andrew Ross Sorkin

Comes online in ’25. So when people—when you talk about profitability, when does that happen?

John Bissell

That happens with that ‘25 plan, what we call Origin Two.

Andrew Ross Sorkin

So it’s in ’25?

John Bissell

Yeah. Exactly right.

Andrew Ross Sorkin

And in terms of raising capital, you’re saying that this takes you--this gets you to ‘25, but it looks like you’re going to want to raise more capital to continue to grow that business, right?

John Bissell

Yeah, you know, so we see there lots of sources for financing for companies like ours. You know, we have very, you know, triple A customers with long term offtake agreements on the back end of these plants. We have relatively fixed costs of feedstock going in. So as a result, you know, these projects are quite project financeable. So there are lots of pools of capital that you can draw from for these kinds of heavy capital projects. So while I think we’ll bring in additional capital, you know, it’s not at all clear that, and certainly in the plan, there isn’t anything to go raise additional equity at some point later.

Andrew Ross Sorkin

What is if, and I asked us a lot when SPAC deals or de-SPAC deals take place, what is the comp, right? What is the comparable company that the investors should look at, because oftentimes the investors that were on the SPAC, in the initial SPAC are a different group of people that are going to be part of this on an ongoing basis and how they should be modeling or thinking about your company, and the multiples assigned to it, relative to others?

John Bissell

Yeah, so I think that it’s good question, of course. And I think what I’ll say is investors have often asked us or about other materials companies, and I think there are two ways to think about that. One is, how can you take a high margin materials company right now and then figure out what is that going to look like that’s a really high growth company. Because it, you know, classically, a lot of the big materials companies just aren’t particularly high growth, whereas we, obviously, will because there’s enormous demand for what we’re doing.

And then the other is to look at other companies that are sort of similar in their lifecycle to us. And you know, the one that is the tip of people’s tongues, of course, is Danimer, who I think has done a great job.

Andrew Ross Sorkin

Fair enough. John, we wish you well in this endeavor, and we do plan to and hope to follow your progress. Hope you come on back.

John Bissell

Thanks.

Andrew Ross Sorkin

Hey, thanks.
