On August 14, 2025, interview with Juliette Saly and Nadine Blayney, of Ausbiz.

The following is a transcript from the video interview:

Juliette Saly, Ausbiz: Nadine caught up with Keith Phillips, CEO of Piedmont Lithium, who has outlined progress on the pending merger between Piedmont Lithium and Sayona Mining, branding it a 50-50 merger of equals.

Keith Phillips, Piedmont Lithium: It’s an interesting situation. Sayona is an Australian company; we are an American company. We’re merging, it’s a 50-50 merger, essentially a merger of equals. We each have different securities laws / regulations that govern our votes. Sayona needed to get a majority of shareholders who are voting for the merger to vote in favor, which they did a couple of weeks ago. In the US, a public company needs to get a majority of shares outstanding to vote in favor. So, we got about 40% of shares outstanding to vote in favor a few weeks ago, we had another meeting on Monday where we got 47% and we’re progressing and working really hard to get to 50.1%.

I’m confident that we will get there eventually, we just need retail shareholders to vote. The good news is that the vote so far is overwhelmingly in favor, 97 or 98% of people voting have voted in favor of the deal. We just need more people to vote, particularly in Australia, so happy to be speaking to you about that.

Nadine Blayney, Ausbiz: Okay, so what do you see as the impasse toward the numbers that have been voting so far? Is it something to do with the deal in and of itself or is it a reflection of the apathy toward the lithium sector in general right now?

Keith Phillips, Piedmont Lithium: I think it’s neither; I think it is retail shareholder apathy generally. I’m guilty of this myself, when I get a mutual fund proxy in the mail, I toss it immediately in the garbage and don’t pay close attention to it. Retail shareholders tend not to vote very frequently, particularly in Australia, unfortunately. We have 25% of our stock - we have most of our stock in retail hands, of that 25% is in Australia. The Australian voting turnout was initially very light, it’s been improving day by day with our outreach, so we are optimistic we will eventually get there, sooner the better.

It’s really retail apathy – people like the deal. We haven’t had anybody have a substantive argument against the transaction, it’s really just turning out the vote. People that own the stock today are bullish on lithium, as I am, we’re witnessing a pretty nice recovery over the last couple weeks. The timing for the merger couldn’t be better, bringing the two companies together. We think we have more operating leverage in our businesses than anyone else does. We’re currently producing, we’re the biggest lithium producer in North America, we share a joint venture called North American Lithium and that is an asset that has huge upside as lithium prices recover, as they are doing now. We’re excited and hoping to get the merger vote over the line soon.

Nadine Blayney, Ausbiz: What is at risk here, Keith? If you want to knock people out of their apathy, you’ve got to tell them what’s on the table. I know that the merger would create North America’s biggest lithium player, but put some meat on the bones of that.

Keith Phillips, Piedmont Lithium: Well really, I think both companies are better off together. We’ve been friends and partners for several years. We made our initial investment in Sayona Mining back in 2020, I think it was in December 2020. We were initially a 19% shareholder, we formed a joint venture in Quebec for the North America Lithium asset where Sayona owns 75% and operates the JV, we own 25% and we have a favorable offtake agreement.

The offtake agreement is such that a lot of the benefit of an upside in pricing comes to us, and because of that it is very difficult for the joint venture to agree on capital spending to move forward. Sayona would be required to fund 75% of any capital to build out the asset and grow it further. It’s a huge resource with potential to probably double the annual production and still have a very long mine life. That is unlikely to happen if the JV stays in place, with us having 50% or more of the upside but only having to fund 25% of the capex, so we think simplifying the arrangement makes it more likely the asset will be funded to grow and to increase production, which we think is the right thing for all shareholders. We also have a couple other assets of our own. One in North Carolina in the United States and we’re earning a 50% interest in the Ewoyaa project in Ghana with our partner Atlantic Lithium.

Sayona also has a 60% interest in the Moblan project, which I think is arguably the best greenfield project in Quebec. It’s pretty special. So, I think the portfolio is terrific and the opportunity is for each of the shareholder bases to own half of a bigger, stronger, simpler company. If for any reason the vote doesn’t come through, and I’m optimistic it will, but if for any reason it didn’t, we would each go on our separate ways but that wouldn’t be the best thing for shareholders. The best thing for shareholders would be to bring the two companies together and move forward from there.

Nadine Blayney, Ausbiz: Alright, let’s get your view on this uptick in the price of lithium that we’ve seen. A bit of enthusiasm for Aussie listed lithium companies. Some of it is to do with some supply restrictions coming out of China, which could be just a blip, broadly speaking though, do you think the bottom has been reached in lithium?

Keith Phillips, Piedmont Lithium: We’ve had a couple of false bottoms, false dawns, before, so I don’t want to be overly prescriptive. We’re at pricing even today that isn’t sufficient to incentivize anybody to build new capacity. It’s possible that prices today would incentivize somebody to grow an existing mine or restart something that might have shut down, but you really need $1,200 / $1,300 / $1,400 spodumene before any greenfield project makes sense. We’re not near there yet, so we’ve bounced off the bottom of around $600 a ton to $900 or $950 per ton depending on which price reporting agency you look at, but I think we’re far away from the point where people will actually invest capital and that is what the lithium industry will need.

Lithium demand is growing strongly, EV demand in July was up 27% globally. People talk about the demise of electric vehicles, that is fake news, electric vehicle demand continues to grow strongly globally. There are big opportunities in robotics and other applications. So, we’re very excited about short-, medium- and longer-term lithium demand. At the end of the day, to meet that demand you will need new projects. Nobody is building any projects at today’s pricing unless they are already in construction, nobody is starting something up. We’re still someways away from pricing being at a level that will incentive new development. I don’t know what that timing will be, but I’m very bullish medium term and expect to see strong recovery from here.

Nadine Blayney, Ausbiz: Okay, so Keith, you are looking to get out the votes so to speak. Give us your last pitch to any shareholders out there that might be listening in, that might be watching this interview. I mean, what do they need to do and how soon do they need to do it?

Keith Phillips, Piedmont Lithium: Well, it is very simple. I think we have 60,000 retail shareholders, believe it or not, and of those probably 50,000-55,000 own a relatively small amount and they all think their vote doesn’t matter, but in fact they do. It’s the law of large numbers where we need a lot of people to vote and we’re getting more and more. We went from a 40% vote in favor to 47%, so we’re making progress every day. We’re keeping track every day we’re getting there, every vote counts, and without getting to the hurdle, no one will have the benefit of the merger. We’re confident we’ll get there. I would urge people to vote, I would urge people to ignore the impulse that they don’t own enough to matter, because believe me, everybody does. Anybody who owns the stock, their shares matter.

Our proxy solicitors in Australia, Sodali and PGS Group, have been very active in reaching out to people. People are getting mailings, people are phone calls and texts. I’m getting complaints that people are getting inundated and that inundation is a good thing. We need people to pay attention and to vote.

The deadline in Australia is next Wednesday morning, but effectively from my perspective, the sooner the better. The sooner people pay attention to this and get their votes in the better. We are making good progress, we are optimistic we are going to get there but again, sooner the better. We’d rather not have to extend again.

Nadine Blayney, Ausbiz: Keith, does this also speak to some of the challenges facing those in Investor Relations departments and particularly yours there? I’m not casting shade or anything, but it does speak to the fact that you can’t wait for these moments to get out there an engage with your shareholder base.

Keith Phillips, Piedmont Lithium: Listen, I don’t think anyone has ever accused Piedmont of being shy on the Investor Relations front. We’ve been pretty aggressive for a long time. The challenge I think we’ve had is that institutions largely abandoned the lithium space over the last few years in the downturn. We had a great run from 2020 – 2022, early 2023, it’s been pretty difficult since then. Three years ago we had a lot of institutions in our stock, institutions all vote and it wouldn’t have been a problem. Our shareholder base, like many, had transitioned into retail hands. For an Australian company, it doesn’t matter because they don’t need to get 50.1% of their shareholders to vote, it’s a complete non issue. I think Sayona got 21 or 22% of their shareholders to vote, that was all they needed and that’s great. For an American company, we need 50.1% and if a lot of that stock is in retail hands and particularly if it is in Australian retail hands, where Australian retail typically doesn’t vote, that is a challenge. Its somewhat unique to us and I don’t think it has broader appeal. It’s a lesson learned from my own perspective, personally. But I think really, for us, the US voting turnout has been sort of how we expected. Its just churning out more Australian retail holders, that is happening day by day and we’ll continue to pound away until we get the quorum.
