Good afternoon, everyone. My name is Sean Menarguez, and I'm the Director of Investor Relations here at MaxCyte.

Thank you all for participating in today's conference call. On the call for MaxCyte we have Doug Doerfler, President and Chief Executive Officer; and Ron Holtz, Interim Chief Financial Officer.

Earlier today, MaxCyte released financial results for the third quarter ended September 30, 2022. A copy of the press release is available on the company's website.

Before we begin, I need to read the following statement. Statements or comments made during this call may be forward-looking statements within the meaning of federal securities laws.

Any statements contained in this call that relate to expectations or predictions of future events, results or performance are forward-looking statements. Actual results may differ materially from those expressed or implied in any forward-looking statements due to a variety of factors, which are discussed in detail in our SEC filings.

The company undertakes no obligation to publicly update any forward-looking statements, whether because of new information, future events or otherwise. And with that, I'll turn the call over to Doug.

Well, thank you, Sean, and good afternoon, everyone, and thank you for joining MaxCyte's third quarter earnings call. I will begin with a discussion of our business and operational highlights during the quarter, followed by a detailed financial review from Ron.

We will then open the call for questions. I am very pleased with our third quarter results as our team continues to deliver on the company's financial and strategic objectives.

MaxCyte's platform continues to be the premier cell engineering technology for the industry, enabling the development of a growing set of advanced cell-based therapeutics. Throughout this year, we have invested in our people and capabilities as we seek to take advantage of the growing end markets and support our customers' and partners' growth.

Interest and investment in the cell and gene therapy market remains significant. In the third quarter for cell and gene therapy, we saw an increase in deal making in our industry, both financings and partnerships compared to the previous quarter.

More specifically in our markets, we are seeing exciting private investment in new company formation focused on novel cell types and complex next-generation approaches. Ron will provide more details later in the call, but I want to highlight that we generated very strong third quarter '22 results in our core business with those revenues up 22% year-over-year.

As a reminder, when we refer to our core business, we are including sales and leases of instruments and sales of disposables to cell therapy and drug discovery customers. The year-over-year increase in core business revenue was led by an increase of 27% in revenue from cell therapy customers, while revenue from drug discovery customers increased 4%.

Our global customer base has expanded across all stages of development, and we are particularly encouraged by our traction with cell therapy customers in early development stages, including leading academic clinical translational centers. Our robust strategic platform license pipeline continues to strengthen and expand with potential partners at various stages of development across the wide variety of cell types, approaches and indications.

Outside of our core business, we recognized $800,000 of SPL Program-related revenue during the third quarter, which puts us at $2.8 million of milestone revenue through the end of Q3 and gives us confidence in our full year milestone revenue guidance of $4 million. Our partners' clinical programs continue to make exciting progress.

Although I note that due to the confidentiality of our partnership agreement, we are not able to answer specific questions related to SPL partners, their clinical progress or their respective development programs. In the third quarter, we announced SPL partnership with Vertex Pharmaceutical, a global biotechnology company that invests in scientific innovation to create transformative medicines for patients with serious diseases.

You should note that this agreement does not support programs new to MaxCyte because it is a transfer to Vertex on programs previously under the CRISPR/Casebia partnership. That SPL originally signed in 2017 included the right to use MaxCyte's technology to support gene-edited cell therapy exa-cel, formerly known as CTX001 for hemoglobinopathies.

All key elements of the CRISPR/Casebia agreement transferred to Vertex, including the financial arrangements. Our total number of strategic platform partnerships now stands at 17, and we are optimistic regarding the potential to add additional SPL partnerships this year at a comparable economics to prior partnerships.

Given the strength of our SPL partnership pipeline discussed earlier, we are confident in our ability to continue to add new partners as we look forward to 2023 and beyond. MaxCyte's ExPERT platform is a core enabling technology in our partner's therapeutic development strategies.

Our partners are well funded and leaders in the cell therapy industry developing a wide ranging set of innovative gene-editing and cell engineering approaches. A key element of our strategy in 2022 has been the ongoing investments we are making to support our customers' and partners' success as well as MaxCyte's future success and financial growth.

These investments include growing our commercial teams, expanding in-house manufacturing, enhancing our process development capabilities as well as ongoing product development and reinforcing our business infrastructure. Additionally, we continue to make investments in our application laboratories and teams to support our success in the rapidly growing next-generation cell therapies market as the field expands across broader indications and into novel cell types.

In September, we officially completed our move into our new headquarter facilities in Rockville, Maryland. Our new facility is a major milestone in our growth.

Critically, this facility dramatically increases our instrument and PA manufacturing capacity to support our customers as they move from research and clinical scale to commercial therapeutic scale. In September, we formally launched our ExPERT VLx large-scale transfection system at the BioProcess International Conference in Boston.

The VLx system expands the MaxCyte ExPERT electroporation platform to offer greater scale for development and manufacture across a broad range of applications, such as transient protein manufacture. The VLx offers key benefits, including shortened development time lines, broad compatibility, workflow integration and flexibility to support the bioprocessing market needs during preclinical development and clinical trials.

The VLx system opens up a new market opportunity for MaxCyte, which supports our confidence in our long-term revenue growth. Participants in the bioprocessing market often take a conservative approach to new process adoption.

And as a result, we are initially focused on early access customers, many of whom are existing customers of our current smaller scale platform as we work to build the capabilities and reputation in this market that have allowed us to capture the value of our technology in other markets. The investments we're making in 2022 will advance our ability to support new and expanding markets, engage successfully with emerging therapeutic development programs and companies and support our partners as they move through the clinic towards commercial launch of therapeutic products.

We remain confident in the value of these investments to our existing and potential partners and customers. As Ron will describe in more detail, we finished the third quarter well funded and continue to have a strong balance sheet to support our expected growth.

In summary, we are pleased with our third quarter 2022 results and remain excited about the future, especially in the cell therapy market as we continue to execute on our financial and strategic goals and make investments to drive growth across the business in the long term. I will now turn the call over to Ron to discuss our financial results.

Ron?

Thanks, Doug. Hello, everyone.

As Doug mentioned, we reported core revenue of $9.9 million in the third quarter compared to $8.1 million in 2021, representing 22% growth. This includes revenue from cell therapy customers of $7.9 million, which grew 27% year-over-year, while revenue from drug discovery customers was $2 million, up 4% year-over-year.

Strong growth in PA sales was the key driver of growth in cell therapy revenues for the quarter. We recognized $0.8 million of SPL Program-related revenue in the third quarter of 2022 as compared to $2 million in the third quarter of 2021.

We remain on track with our forecasted milestone revenue of $4 million for the full year. Moving down the P&L, gross margin was 87% in the quarter versus 91% in the third quarter of the year prior.

Margins are heavily influenced by the highly variable level of milestone revenues as well as the mix of products and customer types, and we saw those effects this quarter. Total operating expenses for the third quarter of 2022 were $17 million compared to $11.6 million in the third quarter of 2021.

The overall increase in operating expenses was primarily driven by increased staff in field sales, field science and manufacturing as well as product development expenses and the increase also included growth in sales and marketing expenses, stock-based compensation and occupancy expenses compared with the same period a year ago. Furthermore, we have a healthy balance sheet with a combined total cash, cash equivalents and short-term investments of $233 million as of the end of the third quarter and no debt.

As communicated last quarter, our uses of cash include investments in operating expenses and capital equipment plus approximately $12 million in investments in our new headquarters this year. Based on the growth year-to-date and our robust pipeline, we are reiterating our revenue outlook for 2022.

We expect revenue from our core business [indiscernible] approximately [30%] compared to 2021 core business revenue. And as we discussed previously, the timing of SPL revenues is predicated on our customers' clinical and regulatory progress and, therefore, is fundamentally more difficult to predict than core revenues, which we manage directly, noting that we continue to expect SPL milestone revenue of approximately $4 million for 2022.

Lastly, we believe that our modest cash burn and debt-free balance sheet will support our future plans for profitable growth. We expect to end this year with more than $220 million in cash, cash equivalents and short-term investments.

Now I'll turn it back over to Doug.

Thank you, Ron. In summary, we are encouraged by our third quarter achievements and remain optimistic about the opportunity to lead the industry forward as the premier cell engineering platform technology supporting the development of advanced cell-based therapeutics for patients who may not otherwise have treatment options.

As always, we want to take this opportunity to thank our team, Board, suppliers, investors, partners and the amazing industry that we have the honor of serving.

A couple of questions. Firstly, on the collaborations that you're doing.

Clearly, it's a larger number than -- or a growing number. And you talked earlier about the stage of those collaborations, some of them being earlier and with academic partners.

Now you've always had a number of those. Are you finding that there's an increase in those as your products, the later-stage products are getting closer to market?

Is that encouraging people to use the technology at an earlier age? I'm just trying to get a feel for sort of the top part of the funnel versus the bottom part.

Julie, thanks for the question. And Julie's from Panmure Gordon.

So thanks, Julie. Yes, I think what we're seeing is the pipeline is building with really in 2 areas, what were the areas?

Really, one is cell therapy companies that are in late-stage preclinical development are coming to us. We're also seeing an increase in the new entities informed around more complex cell therapies.

And we've been talking about our interest in building out these translational medical centers, which are also seeing some good uptick on that as well. I think you just saw some recent work that we had published by a number of our peers, including Dr.

Marson. So I think, again, we're seeing growth in the pipeline all the way across the continuous development, which is very encouraging for us.

Yes. That is very good news.

And then just the second question on the VLx. Is there a difference between an early access customer and somebody who's been beta testing it for starters?

And then those early access customers, are they helping you with sort of the regulatory pathway for this? Because my understanding is that with the VLx because essentially you're using -- you're creating transient cell lines, that's sort of the big change in manufacturing that both the customer and the regulators need to get their head around.

Is that what the early access partners are helping you with?

So the early access partners are, in fact, the beta testers we've been working with. And they are helping us understand more about the regulatory challenges and some of the opportunities we're seeing.

So they're helpful. And we also have our own team of people who are working -- trying to understand those issues as well.

The guidance is around using stable cell lines for the reduction of materials for clinical trials is technical. And so we are seeing some potential for other companies who may have used transient produced material for clinical trials and for treating patients.

So most of the transient work, most of these vaccines are made in transient cell items, so there is some precedent there.

This is actually Madeline Mollman on for Matt Larew. You've emphasized how well capitalized you are and how you've minimal cash burn.

I was just wondering, as you think about your capital allocation plans going forward, if there are any specific areas or adjacencies you were looking to move into?

So I think -- Madeline, thanks for the question. So I think what we're interested in is we have a lot of opportunity as we talk to our customers and partners about areas that they want us to add products to.

A lot of this would be natural extensions to our product line. The VLx is one of them.

I think you've also seen us bring out with a number of new disposables and new buffer configuration. So those are both important for customers.

We have an active program going on looking at downstream analytics and process analytics and also some of the pre and post operation processes that we think we could adapt to our technology. But again, I think it's important to note that although we do have a significant cash amount for if somebody, we don't feel as if we have any urgent need to be investing right now.

I think we want to do our homework, make sure we're finding those opportunities that are perfect fits what we're trying to achieve.

Doug, did I hear you right in you saying that there will be additional SPLs to be added this year, meaning that the number moves higher in the next 6 weeks here?

Yes, that's what you did hear.

Okay. Great.

And then just maybe on the installed base and the growth that you've seen there, Doug or Ron, any chance you can maybe update us on just placement growth? I think it was right around 25% last year, 500 or so, up from 400.

So how is the placement rate or the growth rate in placements this year tracking relative to last year's number, if you'd be willing to speak to that?

Yes. It's been healthy, and we're happy with the growth this year, we'll report a full year number or part update at the end of the year as we always do.

So the instrument sales and instrument leases are both important parts of the revenue mix, and they're performing appropriately in accordance with their plan. So we will report healthy number at the end of the year.

Okay. If I could stick one more in here.

Doug, interesting comment on the new company formation. I'm just curious what you're hearing from these sort of de novo opportunities, so to speak, where they may not have a history with a viral approach or a nonviral approach.

I mean how is electroporation being viewed by these folks? Is there anything that's sort of standing out as you're learning about these new entities that are popping up?

I think, Dan, it's a great question. I think what you're seeing is really novel, exciting new approaches to companies are taking toward operating down regulating certain pathways.

And once you do that, they tend to be quite complex and that believe that falls right into our wheelhouse. And typically, they really don't have an alternative, and they're coming to us to help them with the development strategies.

First one, just looking back on the year, you've consistently beat revenue expectations since the Nasdaq IPO. That's clearly a testament to both operational execution and appropriate managing of expectations.

So just as we turn our sights to next year, is there a reasonable or even potentially conservative baseline growth rate for your core business that we can anchor our 2023 numbers to? Or should we stay tuned?

I think the right answer is stay tuned. We're focused on a successful Q4 and finishing out the year and putting the details on our planning for next year, and we'll talk about that in Q4 when we announce full 2022 results.

Okay. Got it.

Next question, just again reflecting on 2022, it would be great to hear whether your expectations around MaxCyte's 2023 SPL pre-commercial milestone revenue opportunity. I guess that's evolved throughout 2022 and then any additional color just to help guide our modeling of the SPL Program year-over-year?

We'll talk quantitatively in the Q1, as I mentioned, but I can tell you that it's pretty straightforward that as we add SPL, they tend to come to us when they're late preclinical and so they're going to move into the clinic and going to build the milestone expectations. And so moving from where we started this year with 14 and we're in 17 now, and we continue to add that potential set of milestones growth along with that to the straight volume.

And if I can just add, there's also the -- we're also seeing some progress with some of our partners are published their progress on their clinical development programs. And as we've discussed, those milestones tend to be a bit larger as they move further down the pipeline.

That's great, and I appreciate the graphic on Slide 12. So final question, core business is performing exceptionally well.

I think in our view, the downstream revenue opportunity still isn't receiving a ton of credit. So I just wanted to ask, with the rise in interest rates this year, have you sort of attempted to recalibrate the weighted average NPV estimate per SPL customer?

We haven't redone that analysis. I mean weighted average cost of capital is, I don't know, sometimes a matter of opinion.

So we spend a lot of time recalibrating that along with interest rate changes.

It's Hannah on for Jacob. On VLx, do you have any updated thoughts on the business model here?

Will this be a product sale or lease to customers? And what are the key applications that you're initially focused on for VLx?

So the key initial application will be for monoclonal antibody production, and that's precisely what our early adopters are using the technology with us. In terms of business model, that's evolving.

It's one of the reasons why we're working so closely with these companies to understand what value we look to bring. And as I think we've discussed it and there's some real benefits that we provide to that whole process, I mean we're looking to reduce product development time lines, which is critically important.

I think even more valuable with the current financial situation, one of these early-stage companies. It's a technology that needs to be broadly portable in the number of difference in putting out workflow and sure that we can integrate it and ensure it also expectable.

And so all those things are components of how we will determine the value that we bring to the market, and we'll do our best to ensure that we gain as much value as we can at the appropriate value for the technology. But we haven't been public on in terms of what the exact model of data stage here.

This is Vidyun on for Mark. So on the SPL front, do you have any updated views on the addressable market?

I think in the past, you've highlighted potential for 50-plus SPLs. So I just wanted to get your thoughts there considering the launch of the VLx as well, potentially opening up some more avenues?

So the VLx is part of the initial application focus will be in protein production, which is on the drug discovery side of our business, not on the cell therapy part of our business. So just to be clear about that.

I just that number that we came out with the IPO was, I think, more than 50. I think it's fair to say that we believe that number has gone up a bit more than that, although we're really not reporting against that for the future, but only to say qualitatively, it's larger than it was for our product.

Okay. So just a quick housekeeping question.

So could you just remind us where overall headcount stands? I think in Q2, you were actively investing.

And as far as the move to the new headquarters, I know you also cited a potential benefit from in-house manufacturing. So just curious how that's progressing and any contribution to gross margins there?

Yes. So we're above 100 at this stage and on brand with the hiring that we anticipated to in conjunction with the investments that we've described.

I didn't hear your second question.

What was the benefit of in-house manufacturing do in terms of cost dissolvement supporting future demand?

Yes. So thank you, Doug.

So as far as supporting future demand in-house manufacturing is critical to our ability to force the customers to use our technology. And that's the primary reason that we moved in-house because automation is critical, you are being able to satisfy that grow demand.

One of the ancillary benefits that is not really a focus is that when you do automation, you end up lowering the labor cost and component of the processes. So we'll run through the process that you would expect that anyone standing up the manufacturing operations..

Margins on the processing assemblies that come out of our shop, initially are probably lower than they are from our outside manufacturing. And as we build up our capabilities internally after the speed as possible inside our cleaner room, we'll get some benefit on the margin side.

Those effects are very small and so it's not relevant to the change in margins that you saw this quarter for advantage.

Thank you, and thank you all for your interest in MaxCyte and your continued support. Truly an honour to be part of our important and exciting therapeutic modality that we're developing with our partners, and we look forward to answering individual questions after this presentation and meeting with investors during the next several days.

So thank you again for your support in MaxCyte. Thank you very much.
