Thank you, and welcome to Burning Rock's 2022 Annual Conference Call. I'm Yusheng Han, CEO and Founder of Burning Rock. Today, we also have our CTO, Joe Zhang; and CFO, Leo Li. Now let's turn to Page 3. In case there are some investors who are not familiar with Burning Rock. I hereby illustrate what we do.

So our business started from tissue-based therapy selection in 2014 and then expand to multi-directions of liquid biopsy, including liquid-based therapy selection, MRD, multi-cancer early detection, and we have three business units, providing products and services to doctors, pharmas and consumers. Now let's turn to Page 4.

So in this page, we will have a review of 2022. For the general view of our company, we completed profitability-driven organization optimization. The overall headcount have been optimized by 25%. And with this - in that case, we still delivered strong growth in non-COVID quarters and achieved 11% year-on-year growth in 2022.

And we completed listing on London Stock exchange offering an alternative listing venue in addition to NASDAQ. We believe that this is a significant corporate development as it provides a fallback solution to facilitate continued trading and listing of our shares in case of a delisting scenario of ADR on NASDAQ.

We also noted that the latest statement from the SEC in December that as of now, there is no risk of Chinese issuers getting delisted, which is good for us. And for therapy selection, we achieved 13% volume growth despite COVID challenges, driven by in-hospital channel.

And the 9 genes panel was approved by NMPA providing a better weapon or in-hospital model. This is our second approved NGS-based tap by the NMPA and demonstrating our capability of working with NMPA to bring innovative diagnostic products to the market. For MRD, 2022 was a big year in terms of clinical data publication.

We provided initial readout on lung and colon cancer at AACR 2022, followed by additional publications on colon and pancreatic cancer at ASCO 2023. We also expected additional publication on lung this year, AACR.

And commercially, we launched our brPROPHET, our personalized MRD product in March and the volume of patients that were serving keep increasing a very good speed. Biopharma, the new contract value increased 43% to RMB 263 million in 2022 and over 200% revenue growth on strong backlog execution.

And for MRD, oversee was granted FDA breakthrough device designation and standard study for 6 cancer test development was published on Annals of Oncology, as a journal with an impact factor of 51 and it is another strong proof of our technology and product.

The PROMISE study, which is around - which is exactly 2,035 subjects, 9 cancer test development completed and read-out. PREDICT and PRESCIENT study almost 17,000 subjects, 22 cancer test development is ongoing. And PREVENT study, which is a prospective study of 6 cancer test was launched last year.

And our CTO, Joe Zhang, will illustrate more about our early detection study. And now let's turn to Page 5. This page shows what Burning Rock aim to achieve in 2023. So the number one goal is profitability. The goal we set is to breakeven, excluding R&D during a quarter in 2023.

The main reason is that in 2023 and 2024 is still a big year for MCD R&D development. The second goal is continued revenue growth. A healthy increase with profitability is what we want to achieve. Our initial outlook for 2023 revenue growth rate is at 20%.

And the third goal is to further our leading position in MCD as the number one player in China and a top player globally. The main R&D spend, as I said, will focus on MCD this year. And let me break down the goals into four parts. For therapy selection, we'll continue to improve the sales productivity by strengthening the in-hospital model.

And for MRD, launch and installed personalized MRD in top hospitals. Due to the operational difficulties of personalized MRD, it is very challenging to install this method in hospital.

However, since more and more hospitals control the outstanding of tissue samples in MRD baseline needs tissue samples, only an in-house data model can bring the volume of MRD to the next level. And thanks to the efforts of our R&D and operation team, we will be able to launch the in-hospital model of brPROPHET in the near future.

I believe it will be a strong engine for Burning Rock, onco deal and start to impact in Q4 this year. For Biopharma, the goal is to continue its profitable growth. With the new platform of MRD and more international orders, we are optimistic to the growth of biopharma business.

Over MCD PREVENT study, which is a prospective study of over 10,000 subjects, we'll have an interim readout in second half year of 2023. We will continue the development study of 22 cancer test in PREDICT and PRESCIENT. Also, we are building the regulatory pathways with FDA and NMPA, especially NMPA.

The commercialization will go on at selected top hospitals. Let's turn to Page 6. I know that investors care about our financial status. Our CFO, Leo will illustrate more later on. But on this page, I just want to show that we are doing a great effort to reduce the brand rate.

If there's no more big scale clinical trials of MCD, the burn rate will significantly decrease in the coming 2 years. And if there is new trial started, especially under NMPA registration, I think that will be even better news.

So that's what I want to present today, and I will pass the presentation to Joe to talk about our technologies and trials of MCD and MRD.

Joe, please?.

Thanks, Yusheng. So I'm going to introduce some update regards the MCD and MRD. Let's turn to Page 8. So this is basically an update regards to Burning Rock's early detection technology development.

So the - after publication of the basic technology in proof of concept in nature biomedical engineering last year, we actually recently made a good publication - of an oncology regards to the THURDER study, which is a 6 cancer early detection trial we ran past several years.

And so the other very highlight part is basically we got a regulatory breakthrough, which is we grant - FDA granted us the breakthrough device designation early this year. And this is actually a very significant achievement for Burning Rock.

Currently, we're actually working closely with the FDA for the next step to seeking for regulatory approval in the future. So let's turn to Page 9. Basically, this is a slide which we presented previously, talking about the Burning Rock's early detection program, product development roadmap.

As you can see here, for the 6 cancer early detention product, which we oversee. And after the THUNDER study being published in oncology last month, so currently, we are actually running a program called PREVENT study, which is a prospective and interventional intent of use population. And this is ongoing at this moment.

The recruitment is a pretty significant number there. And we probably will update the readout later this year for the first phase. And meanwhile, actually, we are actually developing up to 22 cancer MCD product. There's several trials, several clinical studies related to it yet.

And we already published in poster format in ESMO last year, we call PROMISE study. And at this moment, we're actually in a very intensive preparation regards - preparation stage in the PREDICT and PRESCIENT study, which cover up to 17,000 individuals for this 22 cancer product in the future.

So like I mentioned, there is Slide 10, just to lay out the 6 cancer - 22 cancer program. What steps it is? And I won't cover too much - repeat this anymore. And so let's just talk to - turn to Page 12. I'm going to talk about the Minimal Residual Disease update.

So MRD is actually one of the very important business - new business of Burning Rock in past several years. And Slide 13, talk about the MRD test utility. So there's two kinds of utility. One is the prognosis utility, which has already been proven in a lot of clinical study in the trial.

Another more important utility will be the actionable diagnosis and try to direct this therapy, you can see in left. And in the United States, there are already some CMS coverage regards to MRD utility by some other products.

So that's why Burning Rock actually seeking for all those kind of utilities utilizing our own technology, we call Burning [ph] brPROPHET, which is summarized in Slide 14. So brPROPHET is our technology. It's leveraged on the whole exome sequencing to get up to 50 tracking sites.

And we designed the personalized panel trying to tracking the 50 sites for the follow-up, trying to get the prognosis and as well as therapy guidance utility in the future. So this product already launched last year. We almost like anniversaried the launching at this moment. And Slide 15 talk about the current some MRG-related publication we achieved.

So we are currently – we are keeping - working very hard trying to get a lot of cancer covers. This is basically cancer product indeed. We have already published our non-small cell lung cancer poster in AACR last year, and in AACR happen next month, we will provide update on this non-small cell lung cancer study.

And that can - the patient number will increase significantly. And for the colorectal cancer, we provide two different studies. One study already been published last year in AACR 2022. And there's another one that actually is ongoing. It's a very brief update.

I'm going to talk about it later, basically, it's ASCO-GI this year, early this year in San Francisco, we presented the initial data, but this study is still ongoing, and we are currently actively collecting the longitudinal monitoring data point. And hopefully, we'll get a more readout in the future.

And in ASCO-GI this year, we also have a pancreatic cancer small cohort to demonstrate not only non-small cell lung cancer as well as the colorectal cancer. We can do a lot of other cancer types, including the pancreatic cancer, which is mostly so cancer and also being proved hard to find the MRD in some other study.

Slide - so next slide, Slide 16, basically talking about the pancreatic cancer cohort. So we recruit - actually, we - this is observational study and we collect - and also we collect trendy patient baseline, which is a pre-surgery and as well as some follow like day 7-days after surgery and 30-days after surgery.

And you can see here for pre-surgery, pancreatic cancer, we got 100% positive regards the ctDNA existence, which is showing this very impressive sensitivity of this assay. And we - as you can see here, since there are some of the survival showing the very - very good hard [ph] ratio at 23.45% and showing the prognosis utility of this MRD assay.

And so the Slide 17 is another update regards the colorectal cancer, like I mentioned earlier. So we are actually still working on this. In ASCO-GI 2023, we already demonstrate 127 patients in the initiate cohort. Right now, we almost collect like 220 patient data from the baseline to the continuous follow-up.

And we'll see that there's a lot of data showing here. If you have interest, you can read that in the detail later. And basically, the technology demonstrated very high sensitivity along with very high specificity, which we believe it will potentially generate a lot more utility other than prognosis. So I'm going to conclude my part here.

Let me turn to our CFO, Leo to talk about financial. Thank you..

Thanks, Joe. I'd like to cover three topics. First, let me talk about the fourth quarter 2022 recap. Then I'll talk about the latest trend in the first quarter of 2023, and I'll talk about 2023 initial outlook.

So first, let's go to the fourth quarter recap, and we can go to Page 20, then we can see that we finished the fourth quarter stronger than we previously anticipated. Recall that back in November, we guided for 2022 full year revenue growth to be about 5%, which implies a 20-something year-over-year drop for the first quarter.

We ended the quarter in a stronger performance, down only 3% year-over-year. I'm breaking this down a little bit further, clinical testing revenues dropped in the teens range year-over-year in the fourth quarter, slightly better than we anticipated back in November.

And testing for pharma customers held up very well, maintaining the triple-digit growth rates that we achieved throughout 2022. And we'd like to take this opportunity to commend all our staff who worked tirelessly during the difficult COVID lockdown period.

Our testing carried out pretty much unaffected despite the lockdown suffered by many areas in China and in particular, the city of Guangzhou where our lab is located. We believe the resilience demonstrated by our business, the strong mentality of our staff to overcome challenges will help us in our future growth years.

We also like to recap our 2022 full year performance. Our 2022 full year revenues grew 11% year-over-year. We think this is likely on the high end of growth rates achieved in the precision oncology testing industry by our own estimate. There were three pillars that drove that strength.

Number one, our dominant market position in the in-hospital segment, which we have built over the years into China's number one position. And the second driver is MRD, which is a new product that we launched in March quarter.

We ended the quarter in a stronger performance, down only [Technical Difficulty] We believe this is a multiyear growth runway, and Joe talked about some of the initial readouts and the future investments we're going to make in the MRD area.

And the third is the Pharma Service segment, which benefited from our top-performing product portfolio and our leading position in the companion diagnostics regulatory approval capabilities in China. We think these three pillars will continue to drive our growth in the future years.

Now moving down on our P&L, we grew our adjusted gross profit, which excludes noncash depreciation and amortization by 12% in the 2022 full year, which again sensed [ph] year-over-year.

I'm breaking this down a little bit further, clinical testing revenues dropped in the teens range year-over-year and is likely towards the high end of industry performance by our own estimate. Now moving down to the OpEx lines.

As mentioned in our previous earnings calls, we continue to deliver OpEx reductions as we deliver on efficiency improvement initiatives. All three OpEx lines dropped in the fourth quarter as we focused on improved sales net productivity - sales productivity, reduction in corporate overhead and better focus on our R&D projects.

If we look at the metric of gross profit minus SG&A, so take the adjusted gross profit line and substract the sales and marketing and the G&A line, where you can see that we're showing on the slide here, we're getting closer fourth quarter slightly better than we anticipated back in November.

And testing for pharma customers held up very well, maintaining the triple-digit growth rates that we achieved throughout 2022. And we'd like to take this opportunity to commend all our staff and closer towards breakeven. And we anticipate to hit breakeven at some quarter by this metric during 2023.

The drivers behind this was laid out in our CEO's remarks. We are driving our commercial business units towards profitability, while our R&D is going to be mostly on multi-cancer detection, which will be more focused than the previous years.

So in summary, operating efficiency and breakeven, excluding R&D expenses is going to be our number one priority for 2023. Next, I'd like to talk about our latest trend, and we present our latest volumes on – who worked tirelessly during the difficult COVID lockdown period.

Our testing carried out pretty much unaffected despite the lockdown suffered by many areas in China and in particular, the city of Guangzhou where our lab is located. We believe the resilience demonstrated by 19 of the slide deck.

We can see that the fourth quarter dropped double digits compared to the third quarter, where the central lab segment dropped a bit further. And breaking out into the latest month, we can see that we hit a bad trial in December and January as COVID ramped through China, but we have returned to positive year-over-year growth in February.

Regarding the first quarter, given the sharp drop of volumes in January, which brought the December effect - sorry, which brought the January, February, two months combined volume business, the strong mentality of our staff to overcome challenges will help us in our future growth year to a decline of 20 We also like to recap 8% year-over-year, our 2022 full year performance.

So we think it's prudent to [indiscernible] Our 2022 full year revenues grew 11% year-over-year. We think this is likely on the high end of growth rates achieved in the precision oncology testing industry by our own expectations for the first quarter moderate. And next, I'd like to talk about our 2023 outlook.

For 2023, we have two financial metrics to track. Number one is what we talked about is the adjusted gross profit minus SG&A. We like to hit breakeven on that metric, some quarter during 2023. And second, we like to continue to deliver top line growth. And out of the two objectives, number one, is of higher priority for us.

And within that context, we are guiding initially for a 20% increase in revenues in 2023. We'll keep track of our latest progress and update you on our guidance in our next quarterly result, summit. There were three pillars to that.

And lastly, to recap our – of drove that strength, number one, our dominant market position in the in-hospital segment, which we have built over the years into China's number one position. And the second driver is MRD, which is a new product that we launched in March. We believe this is a multiyear growth runway.

And Joe talked about some of the initial readouts and the future investments we're going to make in the MRD area. And the third is the Pharma Service segment, which benefited from our top-performing product cash position and future burn rate estimates, which we showed on Page 6 during our CEO's opening remarks.

We are sitting close to RMB 1 billion of cash balance. We are sitting on 3 years of cash runway, assuming no capital raise and our cash balance covers all the clinical programs that we have in place. So we would not be in a rush to do any capital raise. And that concludes our prepared remarks. We'd like to open for questions, please..

Thank you. [Operator Instructions] We will take our first question and the question comes from the line of Alexis Yan from Morgan Stanley. Please go ahead. Your line is open..

Hi. Thank you for taking my questions. I have two questions.

Number one is that regarding the 2023 revenue growth target of 20%, can you help us maybe better understand how much of that would be from the existing therapy selection portfolio? And how much would be from the MRD as well as the early detection product portfolio? It may also be helpful to get a sense of MRD contribution in 2022 as context? And second question is that so for the new businesses like MRD and early detection, what are some of the key commercial milestones for example, hospital contracting that we could be – we can track for the next few years? And also, in terms of sales and marketing or market education investment, how do we assess the ROI in terms of these commercial investment?.

Thanks for your question, Alexis. I am Yusheng. So for your first question, we don't - we don't - like I have a very clear cut of which part will contribute how much to the percentage of our growth. I can give you a general view that since as – let's take the three parts, OncoVue [ph] pharma and also early detection.

So OncoVue, I think that will be the - still be the main driver. As you know that we have a big baseline of OncoVue, including therapy selection and MRD. And for - within OncoVue, as I said that the in-hospital model of MRD will impact on Q4 as we completed some in-hospital installment of personalized MRD technology into that.

So before that, I think the therapy selection will be the main driver, including tissue-based and also liquid-based. And for pharma, I think they will continue the growth, especially with the revenue. And I think that trend is good, but compared to the big baseline for OncoVue, I think that OncoVue will be the main driver.

And for multi-cancer early detection and commercialization, I think that it's still - the number is still - cannot be compared with the rest of to be used. But that can also answer your second question is that multi-cancer early detection, we have installed probably around 50 - sorry, 40 hospitals. Half of them are big hospitals.

But as you expected, we need to do more marketing activities to educate the doctors in Class IIIA hospital for them to understand the product and know how to prescribe to the consumers. So yes, I think that the growth rate of multi-cancer early deduction this year will be good. But I cannot give you the exact number of how much we can achieve.

But one thing is sure that since we are controlling the burn rate, we are focusing our energies and headcount cost and marketing activities on Class III hospitals.

Does that answer your question?.

Yes. That's all my questions. Thank you..

Thank you..

Thank you. There are no further questions. This concludes today's conference call. Thank you for participating. You may now disconnect..
