Operator
Thank you for standing by, and welcome to the Iris Energy Earnings Call First Half Financial Year 2022. I would now like to hand the conference over to Mr. Dan Roberts, Co-founder and Co-CEO. Please go ahead.
Daniel Roberts
Hi, everyone, and welcome. We're sitting here today and thrilled to engage in our inaugural earnings call, so thank you for dialing in. And we look forward to the discussion. First things first. As a matter of housekeeping and to keep the lawyers happy, I'll just draw attention to the disclaimer. I'm not going to propose to read it out in full, but there will be forward-looking statements, non-IFRS financial measures, industry and statistical data. Encourage you to read and review that in your own time, but on to the business. So who are we and what we -- what do we do? We're a sustainable bitcoin miner. We build, own and operate our own proprietary data centers. And we've really been focused on not just using excess renewable energy since inception but also really focused on ensuring that we enter markets where we are solving problems, delivering positive externalities. So today, the structure will be I'll give an overview, a little bit more of who we are and what we do just given it's our inaugural call; give a bit of a refresher for those that do know us. I'll then look to pass over to our President, Lindsay Ward, who will take you through some of the specific sites under construction; give you an update on progress, operations and the like. And then finally, I'll pass then to Anne, who will run through the numbers and our record results. So without further ado, I'll move on to a little bit more about who we are and what we do. So I think where we'd like to start this is to really set the scene. In a sector that is often hard to understand -- and we found it difficult at first as well, crypto, bitcoin, the sector more generally. There's a lot of narratives. There's a lot of information. And sometimes, it's difficult for investors to really understand and get their head around what is important. So for us, we've operated under a framework of the 4 Ms. And I think, back to when we started this business 3 or 4 years ago in Sydney, in Will's apartment in Surry Hills, Sydney, and saying, "What's important?" -- and at that point, we set it on the triple M. We didn't really have the fourth M, being management. And it comes down to miners, megawatts, money and management. They are the key ingredients to build and operate a successful bitcoin miner. To step through each of them. The miners, the computers, really simple. You buy these computers. You plug them in. They crunch this algorithm. Every day, they generate bitcoin, which in our instance we liquidate today. It's really simple. Plug them in. Sync them into the network. Generate bitcoin. And that's the model for your revenue line. You then need power. You need access to energy. They're energy intensive, as we all know, so how do you secure that power? How do you ensure that it's sustainable, not just renewable and green but also long term; and that you've got security over your power? The third M, money. It takes money to bring all that together. You need money to build out substations, money to pay for the electricity and money importantly to procure the mining machines. And then the fourth M is management. In order to ensure that you can build at scale, build with risk in mind and build a long-term business, you need a management team whose experience can bring those 3 key ingredients of miners, megawatts and money together. So that's a framework that we really like to communicate today. And I'll spend a little bit more time on each of those Ms, in the hope of educating a little bit more on how we're approaching this sector and our business more generally. So moving on to miners. Again these are your revenue generators. Can you get the chips? Can you install them, and can you operate them? So to date, we've secured 15 exahash of computing capacity. Some of that is operating. The rest of it is under construction at our sites across British Columbia and Texas, which I'll get to. The majority of that capacity is with BITMAIN. We have an average price of circa $40 a terahash, so circa USD 600 million in totality. Obviously that compares favorably to current market conditions where we're seeing somewhere $60 to $80 a terahash, and we're obviously pleased to be in this position. In terms of deliveries of those miners. They remain on track, on schedule. Every month, we are receiving the hardware from BITMAIN. It's been shipped on time. We're often asked about COVID, logistics issues, shipping. It is impacted. I'm not going to -- we've just got to deal with the world that we're in today. Shipping costs are up. We are paying a bit extra for it. It does take a few extra days to clear the ports and get to site, but the most important thing is the chips continue to be shipped. We continue to receive them and we continue to build out our platform. If we move to the next slide. We're talking about megawatts. So where are we going to plug in these machines? And what does that look like? So Canal Flats, our flagship site, has been operating for a few years now. It had an initial capacity expected of around 0.7 exahash or 700 petahash. We've managed to bump that up to 800 petahash or 0.8 through a combination of more efficient hardware and optimizing our operating conditions on site. As mentioned in that table, it's complete. It's been operating and it's going extremely well. It's also provided the basis upon which we've iterated our proprietary data center design over the last few years. So as we'll get on to a little bit later, we don't do shipping containers. We don't do old warehouses. We build our own proprietary data centers, where we've invested a lot of time and energy in optimizing the ventilation and the infrastructure to ensure that we're building out long-term infrastructure and chasing those operational efficiencies. In terms of the next sites, we've announced 3: Mackenzie, Prince George, both in British Columbia, Canada; and another site in the Panhandle in Texas. To go through each of those: Mackenzie has a total capacity of 50 megawatts. We expect all of that will be online by the end of Q3. And the first 9 megawatts, we expect to be online by early second quarter. The reason we can bring that 9 megawatts on a little bit earlier is because we've been able to tap into the distribution line, so the lower-voltage transmission line, to get some initial capacity up and running. And we expect that will come online, as I said, early Q2. Prince George has a total capacity of 85, of which 50 we expect to be available and operating sometime in Q3 as well. Construction, Lindsay will go through in a little bit more detail. And an additional 35 megawatts in 2023. The final site that we've announced is a 600-megawatt site in the Panhandle. We have signed a connection agreement, and construction has commenced on the substation there. Again Lindsay will give you more detail, but where that leaves us in totality is line of sight on clearly installing the 15 exahash that we've contracted for; as well as excess capacity of around 7 exahash, where we have the option to go and procure additional hardware in due course and install it at that site. It's also really important to note that we still have an additional growth pipeline of over a gigawatt beyond these 765 megawatts across Canada, the U.S. and Asia Pacific. We've got a development team internally. They continue to engage in new markets, talk with utilities, work with local government regulators and energy companies to work out where we can continue to grow and support these energy markets. The -- just moving on, sorry, navigating slides, moving on to money. So the third M. So capital is what makes all of these and -- able to happen and to facilitate it. So we're obviously delighted to be the first bitcoin mining IPO led by the bulge bracket banks. I think we had 9 banks and/or advisers listed on that page support us through that IPO. They've continued to be extremely supportive thereafter and really happy with where we got to. We've raised around USD 500 million to date, of which around 90%, about USD 450 million, is through equity and about $50 million through hardware financing. We've had a few questions around fully funding the 15 exahash. So will you need to come back to market? Are you going to need to dilute? Do you need equity? And our position to date is and remains we do not expect to come back to the equity markets to raise any additional capital to fully fund that 15 exahash. We expect to fund that through additional non-dilutive funding options such as hardware financing and corporate debt. We'll give more detail in due course. As always, we'd rather tell you what we've done rather than what we plan to do per se in detail, but the intention is to provide a pathway to being fully funded in the near term and communicate that to the market. Hardware financing structures are common, for those that are new to the sector. And these arrangements, which we've secured $50 million to date, generally involve financing of the computers themselves, so often it will be lending into a special-purpose vehicle where the lender will take security of those machines and lend an amount of capital against those machines. In some instances, the loan-to-value ratios can approach 60%, 80%. So we don't expect any issues there. We've got time. This is a 12-, 15-month CapEx profile; and we'll continue to update the market as we make progress in that regard. If we move to the next slide. The fourth M is management, so a little bit about us. And some of you will have heard this before, but my background, PwC then Macquarie across Sydney and London, developing infrastructure and renewable energy projects. I was then involved in establishing an infrastructure funds management business about a decade ago called Palisade. Look, right place, right time. We grew to around $6 billion in assets, ports, airports, wind farms, solar farms, majority greenfield construction assets. My brother and co-founder Will, he was also at Macquarie doing structured products into traditional mining businesses; and in fact, was involved in setting up their digital asset team back in 2017, 2018; and as part of that, though, engaged with the CME futures [ and ] actually invested balance sheet in bitcoin mining. And then it was around early to mid-2018 that we saw the opportunity and jumped out to form Iris. We've been delighted to partner with a number of really experienced, successful people as part of this business. David Bartholomew, just to mention a couple on the page, built a listed energy and infrastructure business in Australia called DUET. He was CEO for 10 years. He's now Independent Chair of Iris, sold that business for about USD 5 billion in 2017. Brian Fehr and Brian Fry are worth flagging as our essentially founding shareholders in British Columbia. So Brian Fehr, Canadian industrialist; really experienced business builder across the construction, fabrication and energy industries. He has the Order of British Columbia, which was actually given to him for his work in regional communities. So being a very good partnership with Brian, we expect that to continue. And then Brian Fry actually co-founded a company called RackForce in the early 2000s, which grew to be Canada's largest cloud computing center -- platform before he sold out about 5 or 6 years ago to a listed company. So that data center, construction [ DNA ], was in the business early, complemented Will and I and our backgrounds early on and really allowed us to develop and iterate these data center designs, which I'll get on to. The final person I'll mention here is Lindsay Ward, who will be talking in a few minutes. I've known Lindsay for a decade. We worked together at Palisade. He ran and operated the majority of the infrastructure businesses, extremely seasoned infrastructure operator and builder. Delighted to have him join the business last year, having worked for the -- with him for the majority of the past decade. And it's been fantastic to have him alongside Will and I in delivering upon the plan in front of us. So moving on. We have had a number of broker reports initiated on the business, as you can see from below; encourage you to reach out if you have relationships with these advisers. Some of their reports are extremely well done, detailed and analytical. Again encourage you to reach out to those names listed below if you'd like to read them. If you don't have those relationships, don't hesitate to reach out; and we'll see what we can do to help facilitate. Now a couple of other things just before we pass off to Lindsay to talk about the specific sites, a few things about our philosophy. So why do we own our infrastructure? Why have we made such a big point of owning, controlling the land, the substation, the grid connection infrastructure, the power contracts, our own data center design? We own and operate the computers. Really it all comes down to risk. Like we have backgrounds in long-term infrastructure where we're used to thinking 10, 20, 30 years asset management plans; locking down risk; delivering long-term stable cash flows. Now obviously the stable cash flows in this sector are subject to a commodity price, being bitcoin, that is not so stable, but that philosophy still resonates through build out long-term infrastructure, manage your operations and structure it the right way. So by ensuring that we own and control the whole stack, we [ get ] ourselves a lot of certainty around the future. Because we own and power our own data centers, we don't need to rely on short-term contracts, lease agreements, hosting agreements, rolling over the risk that we don't -- aren't able to roll them over and aren't able to secure that capacity, the risk that the terms changed. It also gives us a lot of operational efficiencies. Because we own and control the whole stack, we're highly incentivized to optimize that bottom line. There's no misalignments of interests between the infrastructure owner and the computer owner, and this is starting to come through. And I'll show you on the next slide some of the efficiency data that's now being published by some of the analysts. And then the final thing is, when you own and control everything, it gives you enormous flexibility. And we've mentioned power price flexibility in the bottom row because, when we control that interface with the energy market, we can respond to pricing signals. So we saw another deep freeze in Texas recently. When the wind blows, the sun shines, we can mop up all that cheap surplus power, but when there's a weather event, network outage, some other reason that power prices peak, we directly interface with the market and can respond to that and dial that back, the energy consumption on these chips. The other aspect of flexibility, which isn't actually flagged in this slide, is capital structure flexibility. When you own and control the whole stack, it opens up incredible options, hardware financing, traditional project finance, corporate facilities. When you only own some or part of it, then you may be a little bit less -- more limited in the options that you can pursue. And capital structure flexibility and pursuing different capital market opportunities is certainly a focus over the next 3 to 6 months. So as I've mentioned a few times, we build, own and operate our own proprietary data centers. And again it's been all about optimizing operating performance and ensuring asset life, so we don't put these in shipping containers. We don't let them overheat. We don't let them get dusty. These chips, as we all know, are extremely valuable. They're extremely profitable. Look after them. They will last a long time but not if you let them -- humidity get into them, not if they get dusty. As mentioned earlier, you can see down the bottom one of the analysts on Twitter, Anthony Power, has been collating mining efficiencies across different bitcoin miners. We're pleased to say that -- I think we've been #1 for 4 or 5 months in a row now. And to explain what that means is how efficient are you. Or how many bitcoin do you produce each month based on the amount of computing power you have installed? So hypothetically, if your facility was down half the month, then you're only going to operate at 50% of nameplate capacity. So we're pleased to say that the market is starting to recognize the quality of our data centers. And it's a design that we're continuing to roll out into the new sites -- sorry. Just making sure I've got the right slide order. So as I mentioned before, we've been really focused on not just using renewables. For us, that's a non-negotiable. We've been 100% renewables since inception. For us, that's like the minimum required. It's all about how do you actually get that social license to operate. How do you integrate into these local energy markets, into communities; and bring them along with you for the journey? You're coming into these markets. You're using other people's land, other people's infrastructure, power. You need to give back. It's just the world we live in. And particularly with an industry that we operate in where not everyone understands it, it's really important to give back. We do this in a couple of different ways. So we've got the energy market. In the next slide, we'll get on to the local communities -- but 2 distinct ways that we're helping energy markets today. There's a regulated market such as British Columbia where essentially they've got too much hydro. They're still building large-scale hydro facilities in the north of the province, Site C, in the face of declining manufacturing industrial loads, namely the pulp and paper industry that's declined over the last decade. Now an oversupply of power normally say, "Well, why don't prices go down?" The difference here is it's a regulated market. And under a regulated model, power prices actually have to go up in order for the utility BC Hydro to earn the regulator return on the investment they've made in that generation and transmission infrastructure. So the less customers that are in the energy mix, the more they have to pay to ensure that BC Hydro earns their return. So we come into that market, mop up a lot of that excess spare hydro, give BC Hydro an alternative revenue line and therefore contribute to keeping power prices down for the rest of industry and households in that province. In deregulated markets such as Texas, this is probably a more common example that you've seen elsewhere. It's all about this heavy penetration of renewables. So over the last decade, we've seen a lot of Western markets experience the perfect storm of declining manufacturing industrial loads, the build-out of residential rooftop PV contributing to a net reduction in demand in the market. And then you've had supply-side decarbonization policies basically forcing wind and solar onto these grids in the absence of a market price signal, so not only do these markets need load to support the generation assets that are in place. They also need to solve the system flexibility issue. So again when the wind blows, the sun shines, there's plenty of power. And prices are often negative and in some instances curtailed entirely. The energy is spilt or the generators are turned off, but you get these small number of time periods each year where the market has lost that resilience. They don't have the same baseload capability. And they're trying to solve for these 1% to 2% time intervals, whether there's a weather event, a network outage. Big freeze in Texas is a key example where you need backup gas generating power. You need lithium-ion batteries. Or you need bitcoin mining. Bitcoin mining comes in, mops up that surplus power; and they can provide that system flexibility when the market needs it. In terms of local communities, we've partnered with the local First Nations for our first site in Canal Flats, a CAD 500,000 a year grants program, where we're working closely with 4 of First Nations communities there. We're also engaged in a number of other initiatives around Canal Flats and the broader region. Again it's something that we'll look to continuing to do in the future. We're engaged with similar organizations in respect of our next sites and we'll continue to work alongside communities in which we operate. G, governance. We've [ covered it ] on the E with the power and the renewables, the S with the community. G, as mentioned before, we've been really focused on building an institutional-grade platform that goes to the quality of our infrastructure; our approach to risk when it comes to contracts, ownership of land and controlling our own destiny; ensuring that we're never putting our destiny in other people's hands, but it also goes to a transparent and accountable organizational structure. I mentioned David Bartholomew earlier. He's experienced for a decade building and leading a listed energy and infrastructure business in Australia. His experience is invaluable; alongside Mike Alfred and Chris Guzowski, also very seasoned investors, directors and business builders. We've got all the corporate governance documents you expect, policies, procedures, audit and risk committee. At the end of the day, we are accountable to shareholders. We are custodians of our investors' money. We take that very seriously. And we will continue to safeguard their funds and build out a business very much focused on the long term and through a risk lens. Now on to some of the -- before we do that: HODL considerations. So we've had a few questions. Why don't you HODL bitcoin? Why don't you keep the bitcoin that you mine today on your balance sheet? We are extremely positive on bitcoin. We don't build a business for [ 3 full ] years that is solely relying on bitcoin without being very optimistic, and most of us hold it personally. The thing with the options for this business is that we have options, so one of the things I'll draw your attention to straightaway is about halfway down the first column on the left. The maths are actually quite simple. If we mine a bitcoin today, we have a decision. We say, "Hey, Lindsay, Will, should we keep that bitcoin on balance sheet? Or do we sell that bitcoin to pay for the 10 miners we've got on order that are going to generate a bitcoin every 7 months for us?" We're very bullish on the long term with bitcoin. I think we'd rather deliver a greater exposure to our investors in bitcoin. So today when we've got $40 a terahash in secured miners, while the return on investment is so high, it makes sense to reinvest that cash flow, generating more bitcoin, more upside for our shareholders, rather than just hold a static asset on balance sheet. Now in the future, as and when we deliver substantial capacity, we'll look at that and say, does it make sense to continue reinvesting? Does it make sense to start holding bitcoin on balance sheet? What does the market look like? Does it make sense to start paying distributions? One of the things in bitcoin, [ it's not your key. It's ] not your bitcoin. Are we better off distributing bitcoin dividends to our investors rather than putting them with a corporate custodian and a centralized control of those keys? There's lots of options, lots of consideration. And all we're saying is today the return on investment, as evidenced by that bitcoin every 7 months, is such that it just makes sense to continue reinvesting in delivering first that 15 exahash and then evaluating where we are beyond that. In terms of financials. I've mentioned return on investment. As you can see, we've announced to the market our current contractual profile. To be clear: This is not a forecast. This does not account for any additional [ hardware ] orders. This is only what we have signed binding contracts for and/or have received and are operating today. So we've announced that, by early 2023, we'll have 10 exahash of that capacity installed, delivering a mining profit of around $550 million, $600 million on an annualized basis. The 15 exahash, the last miner is due to be delivered September next year. Once that's all installed, based on the current market, it would be doing around that USD 800 million to USD 900 million per annum in annualized mining profit. We've also attached some links to an online calculator there for those that are interested. The PowerPoint presentation is actually on our website. Feel free to download that. You can play with your own assumptions around global hash rate and bitcoin price. We've then included a slide in this deck, for ease of reference, where we've actually done that. So at the end of the day, the 2 key drivers of mining profitability, once you've got this hash rate installed, in terms of our revenue line: What is the bitcoin price? And essentially what share of that bitcoin are you receiving every 10 minutes by virtue of that global hash rate? So again there's a matrix there with links through to a hyperlink on the calculator. Please reach out if you'd like to discuss and go through in more detail. So on that note, I'd like to move to part -- to hand over to Lindsay, our President. As mentioned earlier, Lindsay and I have known each other for over a decade now. We've worked, for the majority of that time, building Palisade, the infrastructure fund manager. Fair to say it was an absolute thrill to have him join last year and work together on delivering a very exciting platform. So on that note, Lindsay Ward, over to you.
Lindsay Ward
Okay, thanks very much, Dan. And I thought I'd just start with a little bit of background about me. And Dan sort of touched on a little bit of that, but I joined Iris in October last year as President. [ And my ] clear accountability is to take the business from a single current operating site through to a multi-site, 10-exahash business by early 2023. I'm really impressed with the team that's been assembled. Their drive and passion permeates throughout the whole business. We're actively recruiting to ensure we have an operating team that can achieve excellence in everything we do, starting with safety; and that's our primary focus. And then we move on to ensuring that we're very good at environment, community, governance, operations, maintenance, construction and financial control. By way of background. And Dan has touched a little bit on this. I have 35 years in frontline business leadership positions in a range of industries, including traditional mining; baseload power generation; renewables, both solar and wind; as well as having extensive experience in leading multiple infrastructure businesses. I've been involved in a number of infrastructure acquisitions. A majority of that is actually working alongside Dan, focusing on commercial and operational due diligence. And I've led teams that have built wind and solar farms, mineral processing plants, shiploaders, mines and power stations. As Dan mentioned, I worked previously with him at Palisade for about 7 years [ running the ] operational side of that fund management business. And I strongly believe that -- along with Will Roberts, our other Co-founder and Co-CEO, that we've really got an enviable leadership team and capability that will really drive great success to shareholders going forward. So in terms of our Canal Flats facility up in British Columbia in Canada. It continues to outperform. It's been the #1 most efficient miner for the last 3 months, according to a number of various analysts. It is 100% powered by renewables. And it continues to pump out solid cash flows and growing cash flows as we move forward with that operation. Interestingly, we've just had a real cold spell up in British Columbia back in December, minus 30 degrees; and the specialized data center didn't miss a beat. And importantly, it's also operated in temperatures last year when we had a heat wave of 40 degrees Celsius and again functioned beautifully through that period. It's down to our unique airflow system and our recirculation design which really takes advantage of the heat generated by the miners. And it also importantly helps minimize our environmental footprint, as we have no need for secondary heating or air conditioning. The design at Canal Flats has been optimized. We're continuing to learn. And we build those learnings into the designs that we're currently rolling out across our development sites at Mackenzie, Prince George and in the Panhandle region of Texas. On to our first development site which is under construction at Mackenzie in British Columbia, Canada. As Dan mentioned, it's ahead of schedule. We've got 9 megawatts there ready for delivery in early Q2 2022. I must admit it's been pretty impressive to watch the pace in which we've moved from first breaking of ground through the construction and fit-out. It's really important that we lead that construction effort ourselves. We're supported by a great bunch of contractors who really embrace the Iris Energy approach to safety, sense of urgency and our cost focus. And it's this seamless team that we are really building good-quality, long-term infrastructure that are producing strong cash flows for the next 30-plus years. We have commenced recruitment. We're drawing people from the local community. And our presence in Mackenzie is generating significant economic benefit for both the town and the community surrounding Mackenzie. We're already a significant contributor to a number of sporting clubs and service industries, and that will only grow as we implement a community grants program to ensure the whole broader community benefits from our presence. The additional 41 megawatts for Mackenzie will come online in Q3 2022. That site will then be at 1.5 exahash capability. And soon thereafter, we'll turn our minds to how can we improve the efficiency of that site. What opportunities have we identified elsewhere that can be implemented here? And what are our expansion opportunities? Our second site in Canada is Prince George. That's being built at the moment. We broke ground in January. Our first slab will be poured in the next coming weeks. And we'll be rolling the Mackenzie construction team progressively through to Prince George, which brings significant cost synergies and construction learnings. We're very confident that the first 50 megawatts will be commissioned in Q3, and then there's a further 35 megawatts coming online in 2022 -- sorry, 2023. Again we'll be employing locally. We're sourcing locally. It's a real focus of what we do, and there'll be significant flow-on economic benefits to the Prince George community. And I think I'd just like to add that directing -- directly managing the various construction companies and having our own internal construction management design and engineering capability is really a fundamental part of our strategy of building, owning and operating our own specialized data centers. It's really important that we control what we're building so that we've got infrastructure that's going to be there for the next 30 years. Moving away from Canada and British Columbia, we're now down in Texas. We recently announced the signing of what is really a transformational binding connection agreement with AEP, 600 megawatts or 17 exahash of capacity; and we'll be building that in the renewables-rich Panhandle region of Texas. This will allow us to deliver on our 10 exahash by Q1 of 2023 and will leave a significant upside capacity as we move forward with further minor purchases. As many of you will be aware, the Panhandle region in Texas is renewables rich. And really amazing statistic, there's 32 gigawatts of installed capacity, another 6 gigawatts planned, but there's only 12 gigawatts of installed transmission lines down to the major load centers in Houston and Texas, so there's a massive excess renewable capacity that we can certainly take advantage of. It's a 300-acre site. It's massive. It's 100% owned by us. It's in a great location. It's got dual fiber access [ to the gate ]. It's got water access [ to the gate ]. We've got direct highway access, no near neighbors. And I think certainly it's a great opportunity for us to take our installed megawatt capacity from 165 megawatts through to 765 megawatts. And we're working with key suppliers, design engineers, construction companies; and we'll have the first buildings built by the end of 2022. And a key aspect is project delivery. And when you have the knowledge that we have within our business; the knowledge that we've got from building Canal Flats, Mackenzie and Prince George, the project delivery risk with the team that we have assembled is greatly reduced. And in closing, just touching on future development. We've talked about West Texas. We're now at 760 megawatts of 60 -- sorry, 765 megawatts of installed capacity, yes, but we're not done there. We're looking at further growth opportunities. We've got a very agile and capable project development team focused on identifying new opportunities in British Columbia, Texas, other American states and the Asia Pacific. And we've got more than a -- 1 gigawatt of projects under investigation at the moment. We're really excited about these global diversification opportunities, the flexibility and the optionality that they give by having multiple grid-connected sites. And they'll provide great flexibility and optionality for us in the future. So thank you for the opportunity to talk today about the operating side of the business. I'll now hand over to Anne Hayes, who will go through our financial performance. Thank you.
Anne Hayes
Thanks, Lindsay. I'm very pleased to be able to present the financial results of Iris Energy for the first period post the successful IPO in November. So as we see on this slide, we've seen significant growth over the period with our operating hash rate increasing 97% in the December quarter, resulting in 364 BITMAIN -- bitcoin mined, sorry, an increase of 51% on a global hash rate which increased in the quarter by 36%. Pleasingly, our mining, bitcoin mining, revenue increased by 93%, attributable to higher average bitcoin prices. And our adjusted EBITDA increased by 156%. We've shown adjusted EBITDA, which is a measure that's used by management, as the half was marked by nonrecurring items as a result of the IPO and noncash expenses which I'll explain on the next slide. So whilst our net profit after-tax for the 6 months was a loss of USD 419 million, it's important to call out the impact of nonrecurring and/or significant noncash items. The hybrid financial instruments converted to equity just prior to the IPO and resulted in a noncash $419 million expense in the profit and loss account. This is caused by the increase in value of Iris shares since the notes were first issued. The converted instruments are recorded as issued capital at fair value, and any increase in that fair value from the last time it was recorded is treated as a noncash fair value loss in the profit and loss account. Now all of these instruments have now been converted, and it will have no further profit and loss impact to the accounts. The share-based payments expense, which is also a noncash, is split between the founders and the other executives. The founders shares have a strike price of USD 75 and vesting conditions of between USD 370 and USD 1,850 per share. Amortization of the share-based payments takes place over the life of them, so it will continue to be a noncash expense that is taken to the profit and loss account. We also had one-off expenses on the IPO of $3 million which were incurred in the period. So after these nonrecurring and noncash items, the 6 months produced an adjusted EBITDA of $20 million, a margin of 66% on revenue of $30 million. And 2/3 of this revenue was earned in the December quarter alone, with the margin earned in that quarter rising to 72%. This slide shows our statutory financial profit and loss account, again recorded in U.S. dollars, where we've also highlighted on the slide the one-off and noncash items impacting our results for the 6 months so that it's clear. And our balance sheet. The financial position of the group has seen significant strengthening over the 6 months period as a result of the convertible notes issue, the IPO and strong operational results delivering cash flow. Plant and equipment and mining hardware prepayments have increased, supporting the rapid expansion in computing power. Total assets increased from $135 million to $495 million. And total liabilities decreased significantly from $184 million to $49 million mainly as the result of the conversion of the hybrid instruments. This leaves the group in a strong financial position. That is the end of the financial part of the presentation. And I will now hand you back to Dan to wrap up today's briefing.

Thanks, Anne. And thank you, Lindsay. And thank you for everyone that dialed in today for our inaugural call. A couple of quick things that we would have been asked if I had touched on earlier in the presentation. First one is around the power certainty or the access to the electrons in both British Columbia and Texas. We've had a few questions over the last little while around what that looks like, what the price is, et cetera. In British Columbia as a regulated market, once you're connected into that grid or you've got your connection agreement, you've got a regulated right or a legislative right to receive power and export power from the grid. The price you pay is the same price per kilowatt hour 24/7. It's a set price every year. It's an industrial range. It's on the BC Hydro website. It's equivalent to around USD 0.049 to USD 0.05 a kilowatt hour all in, 98% renewable content. And then we are topping up with 2% RECs as an additional purpose -- purchase to round out 100% renewables. So that's quite straightforward. In Texas, the key is the connection agreement. The key is working with the utility to find parts on a network where there is substantial availability of power in that part of the network. Once you connect into that network, it's then just a function of what the market price of power is. So working with AEP, signing that 600-megawatt connection agreement, that was all done on the basis of analyzing that part of the network and understanding that there was 600 megawatts worth of electrons available for us to take from the network. In terms of the specific power price, we'll obviously look to contract that in -- closer to operational start date rather than paying for expensive hedges and contracts upfront, but the guidance we can give is -- and it's all publicly available information, is ERCOT around that area is around $0.03, $0.035 per kilowatt hour base load, but the key is the demand response to the ancillary services. So as I mentioned earlier, it's at 1%, 2% time intervals each year. So it's when the power price really spike, above $1,000 a megawatt hour. If you've got a manufacturing business or a load and the ability to turn off during those time periods, that $0.03 to $0.035 power price drops substantially because a substantial portion of that $0.03 to $0.035 each year is accounted for by these 1% time intervals where the power price goes up significantly. So chopping out 1% to 2% of the time intervals would drop our all-in power costs down into the [ 2s ]. And then if Texas introduces the demand response programs, ancillary revenue programs that are under discussion, all of a sudden not just -- you don't just avoid paying that $1,000 a megawatt hour. There are programs whereby the market may actually pay you that $1,000 a megawatt hour on top. If that's the case, then all of a sudden your power price can drop heavily into the [ 1s ]. And the key again is the operational flexibility. If power price ever becomes an issue, because we own and control all the infrastructure, the power connections, the data centers, then we can adjust our operational profile, turn it down during higher time -- price periods and operate at a lower power price. There are markets around the world that have seen such heavy penetration of wind and solar, where there are feasible models where you can connect in and operate for a large part of the year where you've actually got 2 revenue lines. One, you're paid to mine bitcoin or take the power. So you're paid by the network to take the power because it's negative price. Two, you're then paid to monetize that into bitcoin, so there's a lot of operational flexibility in there, but hopefully, that clears up a little bit around the power price. As we've said all along, we're guiding the market towards an average power cost of $0.02 to $0.04. Where we ultimately fit within that will depend on our operational profile and also the composition of sites across different markets. So for the next quarterly earnings, we will look to implement a Q&A function and have a little bit more interaction, so we'll look to get that up for the next one. Thank you for dialing in. The greatest takeaway, our hope, is that we've got 15 exahash secured. We've got the land and power secured. We've got a team who, ably led by Lindsay, Will and myself, is executing, continuing to deliver. And we appreciate all your support. And again thank you for your time in dialing in today. Thank you.
