Thank you, Joelle. Good morning, everyone, and thank you for joining us to discuss Hut 8's results for the 2022 fiscal year. I will start by restating the obvious. 2022 was a challenging year for our entire industry. For us, this meant that pivoting and changing was essential.
This is where our balance sheet-first approach, which has been in place since the early days of the previous bull market, enabled us to continue pursuing opportunistic moments throughout the year, closing our acquisition of five high-performance computing data centers and integrating them into our business operations, managing through the ETH merge last fall, expanding our leadership team and growing our team members to over 100 across British Columbia, Alberta, and Ontario, continuing to advance our ESG goals by finding innovative ways to e-recycle our miners and computing infrastructure, and self-mining Bitcoin throughout 2022 at modest costs despite fluctuating power prices, resulting in a 28.1% year-over-year increase in Bitcoin mined and a 25% year-over-year increase in hash rate, thanks to steadily plugging in new miners throughout the year.
We continue to believe in our expansion into the high-performance computing business as we renovated our flagship data center in Kelowna and refreshed our data centers in the Greater Toronto Area and Vancouver. We welcomed new customers, including Enthusiast Gaming, Zenlayer, and Luxor. We're replacing our networks with new Cisco carrier-grade routing and switching hardware. We're re-architecting our network carrier uplinks to provide increased resiliency, diversity, and capacity. We recertified the organization under our SOC 2 compliance program, ensuring security best practices across 158 unique operational controls. As we look ahead, we are confident that 2023 will be a year of extraordinary growth. As announced last month, we look forward to the future where Hut 8 Mining Corp. and US Bitcoin Corp. will combine in an all-stock merger of equals to grow into a highly diversified U.S.-domiciled publicly traded organization.
The combination will see us with established self-mining operations at five mines, two in Canada and three in the U.S., running a total of 5.6 exahash with 244 MW of total energy available. It will give us six exahash of installed hosting capacity, powered by 220 MW of hosting infrastructure at our site in Texas with clients that include some of the largest miners in the industry. It will take us into the very nascent phase of managed infrastructure operations at two U.S. sites, where USBTC has pioneered a new business model to capture untapped value from the mining ecosystem, which is incredibly exciting.
With managed infrastructure operations, the team goes into a miner's existing site or sites, and runs the day-to-day operations, manages the property, performs maintenance, and importantly, optimizes performance using USBTC's purpose-driven software, which provides real-time monitoring capabilities to optimize the energy consumption of thousands of machines across the site. It also enables profitable participation in demand response programs and can help to balance the grid, improving grid stability while reducing energy costs. Speaking of energy, the US Bitcoin team brings outstanding energy sourcing, management, and hedging capabilities to New Hut, significantly enhancing our ability to better plan around stable and predictable energy usage and mitigate fluctuating prices across markets. We look forward to the expected completion of the business combination in Q2 and beginning to work together as a team.
I'm very proud of our team's commitment to operational excellence across the business and the trajectory of Hut 8. We look forward to continued success in 2023 as a further diversified digital asset mining, hosting, managed infrastructure operations, and high-performance computing organization. Before I turn it over to Shenif Visram, our CFO, who will review our key financial results, I would like to thank our board for their support and guidance, our executive team for their incredible leadership, and our team across the country for their execution across all of our business lines. I would also be remiss if I didn't take a minute to thank our investors for their continued commitment to Hut 8. 2022 was an incredibly dynamic time for Bitcoin and the broader industry, and your support of our organization is very much appreciated. Jaime Leverton, over to you.
Thanks, Jaime. Good morning, everyone. Let's begin with the full year results for 2022. We achieved revenue of $150.7 million for the year, a $23.1 million decrease relative to the prior year of $173.8 million. This year-over-year decrease was driven by the reduction in price of Bitcoin, which more than offset the expansion of our Bitcoin mining fleet and incremental contributions from the high-performance computing business we acquired in Q1 of 2022. Revenue from digital asset mining activities was $133 million as we mined 3,568 new Bitcoin. This compares to $165.4 million of digital asset mining revenue in 2021 when we mined 2,786 Bitcoin.
We increased our mining production by 28% compared to 2021, and our average cost to mine each Bitcoin reduced by 7% relative to the prior year, reflecting more efficient miners deployed, partially offset by higher energy prices in the year. Our high-performance computing business contributed an additional CAD 16.9 million of revenue in 2022, the majority of which is monthly recurring revenue. Cost of revenue for the year was CAD 175.6 million compared to CAD 85 million in the prior year, and consists of depreciation and site operating costs. The increased depreciation expense from CAD 23.3 million in 2021 to CAD 93.9 million was driven by the increased number and overall cost of miners deployed during the year, and CAD 5.1 million of additional depreciation from the newly acquired HPC business.
Site operating costs increased by CAD 20.1 million to CAD 81.8 million from 2021. Within the digital asset mining operation, site operating costs increased by CAD 11.7 million, consistent with our expansion of mining fleet and increased power costs. We incurred CAD 8.4 million in operating costs related to the high-performance computing operation, all of which are incremental year-over-year. In terms of margin, our digital asset mining operation generated profit of CAD 60.4 million versus CAD 108.1 million in the prior year, reflecting the combination of lower Bitcoin prices and increased electricity costs. General administration costs for the year were CAD 49.8 million compared to CAD 40.3 million in the prior year.
The increase was primarily due to a combination of higher personnel costs, insurance premiums, and other costs, largely in support of the high-performance computing line of business. We recorded a net loss of CAD 242.8 million for the year, compared to a net loss of CAD 72.7 million in the prior year. In the fourth quarter of 2022, the company conducted impairment testing of its three digital asset mining cash generating units, also known as CGU, Medicine Hat, Drumheller, and North Bay. Due to depressed digital mining economics, specifically the decline in price of Bitcoin, throughout periods during the year ended December 31, 2022, the company recorded an impairment charge on its digital asset mining CGUs.
The difference between the pre-impairment carrying value and the recoverable amount of the company's digital asset mining CGUs is $98.6 million. Due to the Ethereum Merge during the year ended December 31st, 2022, where the Ethereum network changed its consensus mechanism from proof of work to proof of stake, the company recorded an impairment charge on its GPU mining group assets as a result of being unable to find an alternative digital asset to mine with profitable mining economics. The difference between the pre-impairment carrying value and the recoverable amount of the company's CGU mining group of assets is $15.2 million. The combined impairment booked in Q4 2022 was $113.9 million. As a reminder, this is a non-cash entry.
Also impacting the net loss, we recorded a $134.8 million non-cash loss on the revaluation of our digital assets as a result of a decrease in the price of Bitcoin. We incurred a non-cash gain of $98.8 million on revaluation of our warrant liability compared to a $114.2 million non-cash loss in 2021. The remainder of the net loss was primarily driven by the lower revenue from digital asset mining operations and higher cost of revenue in 2022. Reflecting the operating results discussed previously, Hut 8 achieved adjusted EBITDA of $32 million for 2022, compared with $96.6 million in the prior year.
Our balance sheet remains healthy with minimal debt and a cash balance of $30.5 million as at December 31st, 2022. On August 17th, 2022, we entered into an equity distribution agreement pursuant to which we established an at-the-market equity program with maximum proceeds of up to $200 million US, approximately CAD 270.9 million. As of December 31st, 2022, we raised $32.8 million US net proceeds, approximately CAD 44.1 million under this program. We have now ceased issuance under the ATM program given the currently proposed business combination with USBTC. Our Bitcoin holdings are marked at fair value and totaled $203.7 million as at December 31st, 2022, based on 9,086 Bitcoin held in reserve.
I will now turn to our Q4 results and provide some additional commentary. Our fourth quarter results for 2022 were impacted by the reduction in Bitcoin prices and our ongoing dispute with Validus related to our North Bay mining facility, where we stopped mining in mid-November. We achieved quarterly revenue of $21.8 million compared to $57.9 million in the prior year's quarter. Revenue was impacted by a substantial drop in Bitcoin prices. The average Bitcoin price in the quarter was approximately $24,600 compared to approximately $70,400 in the same quarter a year prior. We mined 698 Bitcoin this quarter compared to 789 Bitcoin in Q4 2021.
The reduction in mined Bitcoin is due to electrical issues at the Drumheller location and a higher than normal level of curtailing due to a sharp increase in power rates. We also generated CAD 4.5 million in revenue from the high-performance computing business in the quarter, while we generated CAD 2.4 million in revenue from hosting during the same period in 2021. Cost of revenue was CAD 45.2 million in Q4, 2022 versus CAD 27.3 million in Q4, 2021, with the increase driven by increased depreciation expense as a result of our expanding our mining fleet. The cost of mining each Bitcoin for Q4, 2022 was approximately CAD 20,100 compared with approximately CAD 22,800 in the same period a year ago.
General and administrative expenses were $14.8 million for the fourth quarter versus $14.1 million in the prior year period. We had a reduction in sales tax due to lower purchases in Q4 compared to Q4, 2021. This was offset by the inclusion of SG&A related to the HPC business. We reported a loss for the fourth quarter of $186.7 million, compared to a loss of $99.1 million in the prior year's quarter. As previously discussed, we took an impairment charge of $113.9 million this quarter. In addition, we recorded a $37.2 million non-cash loss on the revaluation of our digital assets as a result of a decrease in the price of Bitcoin.
In Q4 2021, we booked a CAD 114.2 million non-cash loss on the revaluation of warrant liability compared to a gain of CAD 4.3 million in the current quarter. adjusted EBITDA was a loss of CAD 3.9 million versus a positive EBITDA of CAD 35.3 million in the prior year's quarter. For the three months ended December 31st, 2022, adjusted EBITDA was negatively impacted by three factors. Firstly, the shutdown of North Bay mining site impacted our Bitcoin mined in the quarter. Secondly, we saw a sharp increase in power rates at our Drumheller site in the quarter, which resulted in lower profitability, higher than normal levels of curtailing, and fewer Bitcoin mined. Lastly, a further reduction of Bitcoin prices had a negative impact on our revenue and adjusted EBITDA. Our balance sheet remains healthy.
We closed the year with $30.5 million in cash. Our debt continues to be relatively low. Our Bitcoin holdings are marked at fair value and totaled $203.6 million as of December 31st, 2022, with 9,086 of Bitcoin in custody. Thank you for joining us. I will turn the call back to our operator for analyst Q&A.
Thank you. Ladies and gentlemen, we will now begin the question-and-answer session. If you have a question, "please press star followed by the one" on your touch tone phone. You will hear a three-tone prompt acknowledging your request, and your questions will be pulled in the order they are received. Should you wish to decline from the polling process, "please press the star followed by the two". If you are using a speakerphone, please lift the handset before pressing any keys. One moment please for your first question. Your first question comes from Mike Colonnese with H.C. Wainwright. Please go ahead.
Hi, good morning. Thank Thank you for taking my questions. First one for me, I saw that you relocated 7,000 miners from North Bay to Medicine Hat. How long do you guys think it'll take to redeploy those miners there? Do you have the sufficient infrastructure and power availability to support the additional capacity?
Yeah. I'll take that one. We've moved miners really into temporary storage for now while we assess various options of where we could redeploy them. We don't currently have that much available capacity in Medicine Hat today.
Got it. I appreciate the clarity there. The next one's for me. You know, if we look at post-merger environment here, you'll be operating several different business lines. How should we think about strategic priorities for the balance of 2023 after the transaction closes and how you intend to allocate capital?
Yeah. We're entirely focused on getting this transaction closed, as you can imagine, and working with the combined teams to plan out the integration. Too soon for me to say where we're gonna be prioritizing capital allocation.
Got it. Thank you for taking my questions.
Anytime.
Your next question comes from Joseph Vafi with Canaccord. Please go ahead.
Good morning, Joe.
Sorry, I was on mute. Hey, good morning, Jamie. Good morning, team. Thanks for taking my questions. I know you probably can't talk too much about Validus, but is there at least a, you know, a timeframe that perhaps we should be looking at where we may get a resolution on that? Then I have a quick follow-up.
Yeah, we, to be transparent, we've had some setbacks at our North Bay site, which affected our results in the latter part of the year, an issue that we continue to be addressing. In November 2022, we delivered a notice of event of default to Validus. As we announced in January 2023, we filed a statement of claim against Validus. In February of 2023, we received a statement of defense and counterclaim from Validus, which denies the majority of the allegations in the statement of claim and brings counterclaims. We believe the counterclaim is meritless and intend to vigorously defend all the claims in the counterclaim while pursuing the claim set out in our statement of claim.
Having said that, these matters are in the early stages of litigation. We can't make any assessment regarding the likely outcomes with a high degree of certainty. Unfortunately, the current litigation means that the North Bay site is not currently operational, as we've discussed, and miners and electrical equipment has been removed from the profit site. As I just mentioned to the prior question, we're assessing opportunities to energize the approximately 7,000 miners from North Bay, which represents approximately 680 petahash of capacity. Given this is a legal matter, we cannot comment further at this time, although I appreciate the question, Joe.
Sure. Absolutely, Jaime. That was a very clear answer. I'm glad that you had it ready to be to say so. That's fair enough. Just, you know, if you kinda look out at the landscape now, I mean, it does feel like, you know, mining today is in better shape than it was a few months ago with spot prices being higher and mining equipment, you know, pricing still hasn't responded that much at this point. How do you feel about the supply side of the business, you know, looking into 2022? I know you got a lot of moving parts. You got to, you know, finalize your merger here. You know, it does seem like mining rigs are attractively priced right now. I'm not sure how long they will be. You know, any thoughts on exploiting this, you know, this pricing environment right now? Thanks a lot.
No problem. We still see a lot of available supply in the market from a miner capacity perspective. The long pole in the tent, as I think we've discussed before, is on the access to power side, but also the power distribution infrastructure. I think we're just gonna continue to assess the market, and again, really focus on getting our merger closed. We're incredibly excited about the increased diversification of New Hut within the combined entity and the optionality it'll give us to strategically pivot as this supply environment continues to adjust.
Great. Thanks a lot, Jaime.
Of course. Anytime, Joe.
Your next question comes from Chris Brendler with D.A. Davidson. Please go ahead.
Hi. Thanks and good morning. Thanks, Jamie, for the questions. I wasn't able to tease out the exact number, but it looks like the gross margins or profit margins in the Bitcoin mining side of the business were came in a lot better than I was expecting to. I saw there was, I guess, a full year number around CAD 20,000 cost per mine. Can you talk about the fourth quarter? If you can, provide some insight into average power costs. Are they increasing? Are they decreasing? The outlook for 2023. Thanks.
I'm happy to turn it over to Shenif to answer your question.
Okay. Thank you, Jaime. Thank you for the question. The cost of mining in the fourth quarter of this fiscal year was $20,100. That compares to $22,800 in the prior year. You know, in the fourth quarter this year, we did see an increase in the power costs that we were seeing, particularly in our Drumheller location, as we saw some stark increases in the power rates there. That impacted our numbers. The offset to that is we did have about a month and a half of mining in North Bay. As you know, we've got favorable power rates at the time with the Validus. At that time, we were mining still. Those two factors, kind of led to the CAD 20,100 average cost of mining in the quarter.
Going forward, you won't have North Bay, but how much does the precipitous drop in natural gas prices help out the outlook for 2023?
You know, I really can't give too much guidance specifically about what the impact will be in 2023. Certainly, you know, we have seen some drop in our power rates in Alberta since the end of the year. You know, we'll hope to see that trend continue as we move forward.
Okay. Jaime and Jennifer, I just wanted to ask an industry question that you may or may not be able to comment on. I'm just thinking about Silvergate and what's happening to the traditional banking system in the United States where, you know, a lot of crypto relatively related companies have been using Silvergate as their banking partner. Where do you stand there, and what do you think it means for the industry?
I'm happy to take that one. Obviously we know Silvergate and the team, although we've never had a direct working relationship with them. There's no direct impact to Hut in that regard. From a broader ecosystem perspective, certainly, it's not something that any of us wanted to see. It's gonna have ripple effects as I think we've already seen overnight. From a Hut perspective, there is no direct implication.
Okay. I'll squeeze in one more if you don't mind. It's, you know, HPC revenue came in almost exactly where I had it, so, you know, solid progress there. With all the hype around AI in the fourth quarter, and I'm sure other companies indicate that, you know, HPC demand is still rising rapidly, can you give us any color on what you expect in terms of how that business could look in this year?
I can't give you any forward-looking guidance, but what I can say is, we are very pleased that we did that acquisition. It's been just over a year since we diversified into that area, and then ultimately we're able to not just integrate the business, but spend a significant amount of time at focusing on upgrading that business. I think we've timed the market incredibly well, and we continue to be bullish on the space and really thrilled that we're a bit ahead of the curve on that diversification strategy.
Awesome. Thanks so much.
No problem. Thank you.
Your next question comes from George Sutton with Craig-Hallum. Please go ahead.
Hello. Good morning, George.
Good morning, Jaime. Also on HPC, just asking the question a different way, can you talk about the key use cases that you currently have relative to the HPC segment?
As I think you know, when we purchased that business, we purchased it with an existing suite of enterprise customers. We've got just under 400 enterprise customers across the 5 data centers, and they're consuming a mix of products from us, which includes colocation, cloud, and managed services. Those customers are from very diverse industries. I think really all major industries are represented in our current customer base. When we kind of look forward and think about the demand profile that we're seeing really increase from, it's we're definitely seeing more inbound demand from artificial intelligence. gaming continues to be strong. Machine learning is another area that got traction. I would say the leading use case right now from a demand perspective that we're seeing in an inbound capacity is coming from AI projects.
Shenif, if I wonder if you could address the Drumheller question this way. You know, your overall cost was CAD 20,100. I'll use $15,000 as an equivalent US dollar amount per Bitcoin. Natural gas prices are down 50% year-to-date. My assumption would be that, you know, you should be seeing those fall. And I'm getting to the curtailment question in terms of trying to understand when you ostensibly would curtail. Is it simply at the production cost number or are there additional considerations relative to that?
I mean, just, you know, first of all, I'm just gonna highlight that in Drumheller specifically, we are investigating some electrical issues at our Drumheller site, which have reduced our overall production there. We're in the early stages of exploring some preliminary options to mitigate the challenges and hope we have more definitive plan ready in due course. It's a bit more complicated in Drumheller in that you're right that we're seeing energy prices drop, but we are seeing an impact on production right now due to electrical issues. A bit more is going into play into the first quarter as we look into these issues that we're having at site specifically. It's a bit more complicated than just the energy price reduction.
I assumed that was the case. Finally, is there any update you can give us on the closing process in terms of things that you are awaiting, in terms of, you know, stipulations or anything that we need to be aware of and any sense of the timing of the close?
Great question. I'll take that. The closing of the proposed merger of USBTC continues to be a top priority, as we've discussed. We're happy to share that we have received a no action letter from the Competition Bureau of Canada in respect of the proposed merger. The letter confirms that the Competition Bureau does not, at this time, intend to challenge the proposed transaction under the merger provisions in the Competition Act. This is a very positive development as we continue to work to obtain all necessary regulatory shareholder exchange and other approvals required to close the transaction. That's as much of an update as I've got for you today.
That was impressive off the top of your head.
You know me, I'm always prepared.
Your next question comes from Bill Papanastasiou from Stifel. Please go ahead.
Hi, good morning, Jaime. Thank you for taking my questions. I just wanna first touch on the high-performance computing business. you know, we've continued to see upward movements in margin performance for the business unit, and you know, they now sit over 50%. Just wanting to hopefully get some more color on how we should be thinking about margins in the long term and how the team's strategizing on what I believe is still excess capacity at some of the TeraGo sites.
Yeah, I'm struggling how to answer that question. We've done a lot of work, as I've talked about, updating the facilities, and I went into some of the specifics already on the call this morning. We've got an incredible sales team in place that's actively driving expansion of the pipeline. I don't know how to get into more specific details, Ricky. We do have some expansion capabilities remaining in a few of the sites. Not all five are expandable. We'll continue to look to expand as required when the capacity that we have built out already is filled up. It's really a data center by data center question as opposed to a fleet demand question.
Right. Great. Thank you. Yeah, I appreciate the color, and I understand that, you know, the data centers will be specifically focused to particular regions, so that makes sense.
Yeah. Thank you.
Exactly. Yeah. Shifting gears to the mining space, you know, the company was able to see, you know, fairly strong gross mining margins just given where break-even electricity costs were and, you know, assumed power costs maybe for these sites. It appears that things are trending in a positive direction in 2023, just based on that same analysis. Given the relationships that you guys have and just your take on the space, with manufacturers, you know, how do you see further consolidation in this space as we approach the halving? You know, are you planning? Do you see an improvement in overall mining economics? What's your take on 2023?
Yeah, I mean, I wish I had a crystal ball. I think, we've all been surprised by the continued growth of the hash rate and difficulty level despite, you know, relatively sideways trading of the Bitcoin price in general. Obviously a nice development that we've seen, natural gas prices come down and as Shannon mentioned, hopeful that that will continue. It's really difficult for us to make a prediction on ultimately where hash rate and difficulty are going to go, as well as Bitcoin price.
What we've always tried to do as a business and our leadership team is make sure that we have optionality built into the system, which for us only increases when we get the merger closed with USBTC. We really believe in the diversified business model that we've kicked off and ultimately, again, expands with this merger, because we really cannot predict where Bitcoin price is gonna go or hashrate in the short term, for sure. Keeping in mind, we're right about a year away from the halving, which has its own unique implications, as I think everyone's aware.
Right. I guess it helps to have that huge Bitcoin treasury too, as we approach the halving and hopefully get the upside there. Thank you for taking my questions.
My pleasure. Anytime.
There are no further questions at this time. Please proceed.
Okay. Thank you again, everybody, for joining today and for your continued support. We truly appreciate it, and we look forward to an exciting 2023 ahead. Have a great day, everybody.
Ladies and gentlemen, this concludes the conference call for today. We thank you for participating and ask that you please disconnect your lines.
