Daniel, Operator

Welcome to the Iovance Biotherapeutics second quarter 2026 conference call. My name is Daniel and I will be your operator for today's call. At this time all participants are in a listen-only mode. Later we will conduct a question-and-answer session. Please note that this conference call is being recorded. I will now turn the call over to Sarah Pellegrino, Senior Vice President, Investor Relations and Corporate Communications at Iovance. Sarah, you may begin.

Sarah Pellegrino, Senior Vice President, Investor Relations and Corporate Communications

Thank you, operator. Good morning and welcome to the Iovance webcast to discuss our second quarter 2026 financial results, business achievements and corporate updates. This morning we issued a press release that is available on our corporate website at iovance.com. This conference call will include forward-looking statements regarding Iovance's goals, business focus, business plans and transactions, revenue and revenue guidance, commercial activities, clinical trials and results, regulatory approvals, submissions, feedback and guidance, plans and strategies, research and preclinical activities, potential future applications of our technology, manufacturing capabilities, payer interactions, licenses and collaborations, cash position and future updates. Forward-looking statements are subject to numerous risks and uncertainties, many of which are beyond our control, including the risks and uncertainties described from time to time in our SEC filings. Our results may differ materially from those projected during today's call. We undertake no obligation to publicly update any forward-looking statements.

I will turn the call over now to Dr. Fred Vogt, Interim CEO and President.

Frederick G. Vogt, Interim CEO and General Counsel

Thank you, Sarah. Iovance is the global leader in innovating, developing and delivering TIL therapy for solid tumors today and for the next generation. The second quarter of 2026 was our strongest yet. We delivered record revenue and margin, advanced our pipeline and secured important new regulatory approvals and designations. I'll start by highlighting a few notable achievements. First, our commercial launch reached new heights in the second quarter while our foundation for growth expanded.

More authorized treatment centers, or ATCs, are activating, enrolling and infusing patients than ever before. We reported $99.3 million in revenue driven by record AMTAGVI demand. We also greatly exceeded both our AMTAGVI and total revenue guidance ranges for the second quarter. Second quarter margin also reached an all-time high of 56%. We expect margin to keep expanding as we increase revenue, fine-tune execution and gain efficiency at scale. Looking ahead, we maintain our peak assumptions for AMTAGVI (lifileucel) of more than $1 billion in U.S. sales from advanced melanoma alone. The opportunity in other indications is significantly larger. Our third quarter performance of data is very strong. Once we fully assess increasing growth trends, we expect to provide an update to our full year guidance during the third quarter. We are now providing commercial AMTAGVI to more than 50 patients a month on top of increasing numbers of clinical patients, which demonstrates both our manufacturing scale and how broadly accessible our cell therapies have become.

We are not choosing between growth and discipline. This quarter we delivered both. Research and development expenses improved for the fourth consecutive quarter, even as every lead program advanced and our pipeline grew. We are closing in on our pursuit of the largest opportunities for cancer patients who have the greatest unmet need. Our technology platform is scaling quickly. Recent regulatory and clinical milestones bring TIL therapy forward for more patients in the U.S. as well as new markets and additional solid tumor indications. Nearly 2,000 patients have received Iovance TIL therapies in commercial and clinical settings across hundreds of centers in the U.S. and in 30 countries. Over the coming years, our vision is to reach tens of thousands of patients. In our registrational trials, enrollment is nearly complete in our Lung 202 trial in the pivotal cohorts in non-squamous non-small cell lung cancer. This indication represents a blockbuster opportunity that is roughly seven times that of advanced melanoma.

We look forward to providing program updates in the fourth quarter as we work toward a supplemental biologics license application in 2027. We're moving quickly with our registrational Saratoga trial, or SAR-201, in two advanced soft tissue sarcomas. As we announced today, the U.S. FDA granted fast track designation in undifferentiated pleomorphic sarcoma and dedifferentiated liposarcoma, validating the promise of the initial clinical data for lifileucel as well as a substantial unmet medical need in both indications.

In a pilot study with one-time lifileucel therapy, the objective response rate was an unprecedented 50% in the first six evaluable patients, compared with abysmal response rates of less than 5% using current standard of care in these refractory treatment settings. Our translational data and state-of-the-art technologies are uncovering the next frontier in TIL therapy. We are now able to identify highly responsive patient populations across solid tumor indications that comprise more than 90% of all cancers.

For example, a histology-based biomarker strategy produced striking early phase 2 data in the first five evaluable patients with metastatic serous endometrial cancer. In our N201 trial, we reported a 40% confirmed objective response rate and a 100% disease control rate. We're submitting a protocol amendment and engaging with the FDA on an expedited approval pathway based on this patient population. Our leadership in TIL therapy includes continuous investment in next-generation programs.

A new trial known as G1201 is using IOV-5001, our next-generation IL-12–tethered TIL therapy. This phase 1/2 basket trial will run across prevalent solid tumors representing more than 100,000 U.S. deaths annually, including metastatic colorectal, triple-negative breast and estrogen receptor–low breast cancers. We expect to provide more updates this year. Today profitability is in sight, and with it lasting value for patients and shareholders alike.

Iovance is the first and only company in the world to take TIL therapy from concept to commercial treatment for patients, supported by our scalable manufacturing infrastructure, clinical breadth, commercial experience and operational discipline. With healthy commercial momentum, a broadening pipeline and solid execution, Iovance has never been better positioned for long-term success. I'll now ask Corleen Roche, our Chief Financial Officer, to detail our financial results.

Corleen Roche, Chief Financial Officer

Thanks, Fred, and good morning, everyone. Our highest-ever quarterly revenue and margin clearly demonstrate our commitment to top-line growth, operational excellence and financial discipline as we build a sustainable self-funded business. Second quarter total revenue was more than $99 million. That is up 66% year over year and 39% sequentially from the first quarter, which had included one-time nonrecurring impact from our internal manufacturing upgrades.

AMTAGVI was the key growth driver, reaching a new high of approximately $91 million in the quarter. We exceeded our second quarter AMTAGVI guidance range of $79 to $81 million. Second quarter AMTAGVI revenue increased roughly 51% over the first quarter of 2026 and 68% year over year, reflecting a robust increase in patient demand and adoption. Proleukin contributed about $9 million in the second quarter, slightly down from $11 million in the prior quarter due to timing of wholesaler inventory stocking.

For the full year 2026, we anticipate that Proleukin as a percentage of total revenue will be in line with 2025, consistent with the prior quarters. Overall gross-to-net impact remains minimal at less than 2%. Margin increased to approximately 56%, up from 41% in the first quarter and above our previous all-time high of 50% in the fourth quarter of 2025, with the year-to-date 2026 margin of 50%. The second quarter benefited from higher AMTAGVI volume, continued cost optimization and maturing internal efficiencies during our first full quarter of manufacturing exclusively in-house.

We are also deploying and advancing artificial intelligence tools to drive significant future cost efficiencies and new product pipeline insights as we expand our business as well as our development pipeline. We are very closely managing operating expenses. Research and development expenses were about $59 million, down from $62 million in the prior quarter, reflecting ongoing efficiency gains as we progress all of our programs. This marks the fourth consecutive quarter of cost savings through R&D optimization.

Selling, general and administrative expenses held essentially flat at about $39 million even as revenue grew roughly 39%, with clear operating leverage from our commercial infrastructure. We expect to gain further efficiency with targeted investment across the business. I will now cover our outlook for the rest of the year. Based on strong second quarter sales, we are reviewing our previously issued full year 2026 total revenue guidance of $350 to $370 million and plan to share more detail in the third quarter.

We are well capitalized to fund both the launch and our pipeline. As of June 30, 2026, we had approximately $304 million in cash, cash equivalents and short-term investments. This cash position is now expected to fund operations into the second half of 2028. When I joined Iovance, the priorities were clear: grow revenue, expand margins and manage spend to reach profitability as quickly as possible. On my one-year anniversary, I am pleased to highlight that all three of these priorities are translating into positive results and lasting value for patients and our shareholders.

I will now turn the call to Dan Kirby, our Chief Commercial Officer, to review our commercial progress.

Dan Kirby, Chief Commercial Officer

Thank you, Corleen. As mentioned, Amtagvi generated record revenue with more patients treated than in any prior quarter. This commercial momentum is carrying into the third quarter. Adoption isn't just growing, it's broadening into new ATCs and earlier lines of treatment. Today I will highlight three commercial priorities powering that trajectory for Amtagvi growth, which are rising physician awareness, continued expansion of our ATC network, and a deepening body of clinical evidence.

The first priority is to continue to increase awareness of Amtagvi among both treating and referring physicians. Unaided awareness has increased nearly threefold over the past year, driven by two factors: 1) a new marketing campaign unveiled at ASCO and 2) improvement in sales force effectiveness measured by meaningful growth in both number of treaters and referrers. The second priority is increasing our footprint across both academic and community settings.

With more than 95 total ATCs today, we are on track to reach at least 110 by year's end. Community ATCs now represent a third of our network and are expected to increase significantly over the next several quarters. Each new ATC is widening our commercial reach to the patients who need it. The third priority is the continued expansion of our already deep, industry-leading clinical evidence. The published five-year durability data and real-world response rates of greater than 50% in patients with two or three or fewer lines of therapy are convincing physicians to adopt Amtagvi earlier.

In addition, at ASCO we released a new survival analysis from our clinical trial. This analysis estimated that the Amtagvi 10-year overall survival for responders would be 46.7%, or almost half. Independently, a growing number of our ATCs are publishing their own real-world experience. Across these studies, response rates and patient outcomes consistently meet or exceed what we observed in our clinical trials, which support the emerging practice pattern of treating patients with Amtagvi as soon as possible after checkpoint inhibitor therapy.

These aggregated real-world evidence data are being deployed across our sales force in conversations with ATCs and physicians. This information can be found on the publications page of our website at iovance.com for those interested. Underpinning all three priorities is ensuring coverage and access. Amtagvi has strong payer coverage. More than 75% of Amtagvi patients are covered by private payers. Payers and plans that cover more than 250 million lives have added Amtagvi to their policies.

Our U.S. ATCs are strategically located in proximity to most addressable patients. More than 95% of patients live within 200 miles and 80% of patients live within 100 miles of an ATC. With our rapidly expanding ATC network and increased community presence, we expect even broader access to Amtagvi throughout 2026. Importantly, we are also proving we can deliver on our promise to patients with a turnaround time of 31 days or less using the only scaled centralized commercial manufacturing process approved by the FDA for TIL therapy.

Demand for Proleukin, our second product, remains strong. All three wholesalers have sold through their previous stocking inventory in the second quarter and are currently ordering in line with Amtagvi demand for the rest of the year. We expect quarter-on-quarter Proleukin growth tied to Amtagvi growth on a steady basis of approximately 16% of total revenue. Outside of the U.S., with two approvals of Amtagvi in Canada and Australia, we are continuing to expand in new markets for previously treated melanoma patients, a globally addressable population of more than 30,000 patients.

Our first ATC in Canada is ready to support international private-pay patients while we work toward public reimbursement. In Australia, I recently visited several of our onboarding ATCs as we collaborate to raise awareness and expand access to Amtagvi. Australia has the highest rate of melanoma in the world. We are opening our first ATCs for private-pay patients while we work with the government on pricing. Looking ahead, regulatory approvals are pending in the United Kingdom and Switzerland.

Elsewhere we continue to work closely with health authorities in the European Union towards resubmission. Together, these foundational international markets augment our growing U.S. franchise for Amtagvi. In summary, demand for Amtagvi is strong and continues to grow. Rising physician awareness is accelerating referrals, a growing network of ATCs is broadening access that is converting into more patients treated, and the deepening clinical evidence is expanding the addressable patient population.

Iovance is committed to serving patients with a one-time cell therapy that delivers meaningful, validated, systemic clinical benefits. I will now hand the call back to the operator to begin the question-and-answer session.

Daniel, Operator

To ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Please stand by while we compile the Q and A roster. Our first question comes from Andrew Tsai with Jefferies. Your line is open.

Andrew Tsai, Analyst at Jefferies

Good morning. Thanks. Congrats on a great quarter. So can you talk about this large upswing in Q2 that even came out well ahead of your guidance? Was it purely due to underlying demand or was there kind of any one-offs in the timing of shipments maybe being more favorable in Q2? Just wanted to check the box on that. And then secondly, on the lung update later in Q4. Just wanted to clarify on the cadence of events we can expect here. Is it fair to assume you would first need to complete enrollment in this pivotal cohort first and then generate follow-up data on every enrolled patient before you top-line the data, or can the top-line data be on the majority of patients, not necessarily all patients, with follow-up? Thank you.

Dan Kirby, Chief Commercial Officer

So I'll take the first part on demand. It's a great question. What we saw in demand was, as I said on the call script, essentially we saw that awareness is increasing among our physician base, both treaters and referrers. We are expanding our ATC network and then the clinical data is evidence of Amtagvi's efficacy. One thing that did happen in the first quarter that helped us in the second quarter was we had the manuscript published on our real-world evidence data that showed over 50% of the patients with two or fewer lines of therapy were responding.

That data helped propel our sales force and our commercial efforts to raise awareness further and encourage more patients to be treated. We expect this to continue and we are seeing this into the third quarter.

Frederick G. Vogt, Interim CEO and General Counsel

I'll just add to Dan. Just to be very clear, Andrew, it's not a timing issue or anything. This is organic demand for the product. It's looking very good right now based on all the factors that Dan described and more, that we really do expect that demand is going to continue to increase significantly for Amtagvi throughout the coming quarters. On the lung, on your question about the lung 202 update: yes, I think it's fair to assume we're going to complete enrollment very soon and we would want to finish that process before we put any kind of material update out.

Obviously, for FDA purposes we want to do that, but I don't think it's fair to assume that we would wait for every single patient to become evaluable. We really want to make sure the integrity of the trial is clean and we have all the patients before we put some data out. Some of the patients may still be coming for their first evaluation, that kind of thing, when we put that out, or maybe not. Depends on the timing and how the data looks. So just stay tuned.

The lung is looking very positive right now. We feel very good about where we stand with the study and we will have a lot, I think, to say about that. I know that's a very key thing for investors and I really urge everybody to watch carefully as we talk about that, and maybe even more than what people are expecting in this space.

Andrew Tsai, Analyst at Jefferies

Thanks so much. Congratulations.

Daniel, Operator

Thank you. Our next question comes from Yanan Zhu with Wells Fargo. Your line is open.

Yanan Zhu, Analyst at Wells Fargo

Great, great. I'll add my congrats on a very strong quarter. Maybe from Fred's comment, it sounds like for the next two quarters you expect the sales to, or the demand to, further build upon the current demand level, or the second-quarter demand level. Just want to see if that's the correct interpretation. And in terms of, given your visibility into the third quarter and perhaps also into the fourth quarter, can you talk about your expectation? And also, the guidance sounds like it's going to come during the third quarter.

Is that the case rather than at the next quarter's earnings call? Perhaps? Also, a question on TILVANCE-301. Can you give an update on where you are? And it sounds like you have a presentation at ESMO. Can you talk about what we can expect in the data there? Thanks.

Frederick G. Vogt, Interim CEO and General Counsel

Sure. Yeah. Let me cover the first two and then Dan can comment, and then I'll come back to TILVANCE at the end. Yes, I think you heard correctly. Demand trends are very positive right now for the Amtagvi product and we expect increasing demand in Q3 and Q4. We're obviously seeing quite a bit of Q3 right now. We want to just evaluate the whole situation because we really focus on long-term guidance here. We want to make sure we can give good guidance for the full year before we announce it.

But you are correct, we are intending to make a separate announcement of guidance. So, you know, one morning you'll wake up to some hopefully very positive news, I think, from Iovance on the guidance as we get that visibility. Can't tell you exactly when, but obviously sometime in the third quarter. But yes, that's very strong. Amtagvi is strong. And as we pointed out, Proleukin demand is very strong. Dan, do you want to comment and add some detail to that?

Dan Kirby, Chief Commercial Officer

Sure. For Q3 right now, as you mentioned, Yanan, we do have pretty good line of sight into Q3 and what's going on right now. The demand continues to grow and so we're very confident that Q3 will build upon the success in Q2, and then Q4, of course, following from that. You know, we've expanded our sales force. We continue to evaluate putting promotional activities in place such as new campaigns, etc., to continue that growth driving not only through 2026 but 2027.

Frederick G. Vogt, Interim CEO and General Counsel

And then I'll come back and answer your question about TILVANCE-301. That study continues to run well. We're very happy with the performance of the study. At ESMO, we're going to, again in an oral session there, highlight some of the compelling clinical characteristics of Amtagvi plus pembrolizumab in the frontline setting, including the fact that almost a third of patients go into a complete response. We have a very rapid velocity of response, meaning we can drive patients into response much faster than other alternative therapies, we think.

And we'll show much more insight, I think, from the predecessor phase 2 study. Obviously, TILVANCE is a randomized trial that we can't look at right now. It's blinded. We'll read that at the interim point, hopefully relatively soon, although these trials take a long time to run, as you know. But we're going to show the compelling clinical characteristics, and I think it's going to be a very important output for people in the field, especially since some of the excitement around LAG-3 has faded, especially post-ASCO with Regeneron's results.

And, you know, LAG-3 is still in some cases being questioned as to whether it's the right combination in the frontline setting. And there really is an extremely large need for something, some alternative to ipi-nivo in the frontline setting for these patients. We think lifileucel's characteristics are perfect for this, with the one-time therapy combined with what may end up being fairly limited pembro dosing and the fact that we can drive a large percentage of patients into what's effectively a cure.

Yanan Zhu, Analyst at Wells Fargo

Great. Thanks for the update.

Daniel, Operator

Thank you. Our next question comes from Etzer Darut with Barclays. Your line is open.

Etzer Darut, Analyst at Barclays

Great, thanks for taking the question. And congrats on the strong second quarter. One question on margins and then one on lung. You had a meaningful step-up obviously in gross margin in the second quarter. Maybe if you could talk about the remaining opportunities to improve margins further relative to current levels and where you think mature commercial margins could ultimately trend to over time, that would be great. And then on lung, obviously the durability exceeds historical benchmarks from what you've previously shown.

Is the internal goal there to replicate earlier data from an efficacy and durability standpoint? And also with enrollment nearly complete, have you continued to enroll patients with similar baseline characteristics from the prior update? Thank you.

Corleen Roche, Chief Financial Officer

Hi Etzer, it's Corleen. So I'll answer your margin question. The driver is a number of things and as you know, we've been focusing on this internally and we've been talking about it. Obviously higher volume, which you can see, but we have all of our manufacturing in house and those efficiencies are also helping margin as well as these projects that we have where we're continuing to focus on margin improvement and operational efficiencies within the plant.

I would think about that in terms of process automation, things like that.

Frederick G. Vogt, Interim CEO and General Counsel

And one other point, I'll just add to what Corleen said. As Dan and others pointed out here already, with Proleukin now normalizing and then Proleukin sales expected to increase this year and then stabilize at the right percentage going forward. Proleukin is a very high-margin product, so you can expect a little bit of tailwind there as well. On Lung 202. I just want to—You asked two questions there, Etzer. One was is our internal goal to replicate the durability to actually exceed the durability?

Because when we reported the durability earlier, we had short follow-up and I think what we're seeing right now, we're not going to pre-release results here. Obviously right now we're seeing very strong durability, I think very similar in overall outcome to what we saw in melanoma. It's effectively the same type of product. When we get a response, it's usually pretty durable. Whether it ends up being two years, three years, whatever it's going to be.

We'll find that out when we do the ultimate stats analysis at the end. But it looks pretty good. I think any of those options are going to be successful in the marketplace in terms of a product that will attract a lot of prescribers and patients to a one-time therapy like that. And then you mentioned with enrollment nearly complete, you asked about the baseline characteristics of the patients. I think we are seeing similar baselines where we don't have a lot of heterogeneity in our population.

We're very comfortable with how we enroll these studies. We've spent a lot of time on our protocols to make sure we get things right. And yes, I think we're seeing similar patients come through right now than we were throughout the study. Obviously we changed our lymphodepletion to make it a little less burdensome on patients and we're seeing really good results with that right now in terms of the safety profile and the overall risk-benefit profile of the product.

Etzer Darut, Analyst at Barclays

Great. Thanks for the color and congrats again.

Daniel, Operator

Thank you. Our next question comes from Rennie Benjamin with Citizens. Your line is open.

Rennie Benjamin, Analyst at Citizens

Hey, good morning guys. Thanks for taking the questions and congratulations on an amazing quarter. Just two questions from us, I guess. One regarding the outlook and the fact that you're reviewing guidance. Can you talk a little bit about what factors go into providing this reviewed outlook and kind of what prevents you from providing that guidance now? And related to that, does Replimune's recent positive FDA advisory committee feedback and maybe even the Obsidian going public, does that kind of impact guidance?

And if not, what are your thoughts regarding at least Replimune's agent coming into the marketplace? And just as a final question, the endometrial study, Fred, you had mentioned histology based patient selection and that there are protocol amendments going on right now. Can you talk a little bit or provide some color regarding the protocol amendments and how that study will ultimately reach conclusion? Thanks.

Frederick G. Vogt, Interim CEO and General Counsel

Let me take the last one first, Rennie, because it's fast. It's a protocol amendment to focus on the sera subtype and it really links up with the disclosure we had last quarter about the response rate that we're seeing and that precise approach to how we deliver TIL therapy to certain histological subpopulations in our studies. We have a lot more to say about that across all the indications soon. On the guidance. What we're doing with the guidance internally is we're going to make sure we understand Q3, but really we want to understand full year.

We're not looking to give guidance that is just sort of short term. We're really focused on long-term guidance to show the strength of the product overall. We really obviously we cater to long investors, long holders of the stock and we want to make sure they have the information they need to understand the overall trajectory. So what we're going to do is make sure we have our demand understood fully. Obviously it's very good. And then we will come back out at some point, which I can't tell you exactly when it's going to be during the third quarter.

And we will announce something that I think everybody will find very positive and persuasive. On the competitor front. Obviously there's a lot of noise out there. I just want to stress that we stay out of this. This is not our situation. Other people have their drama that's going on with the FDA. Obviously that product could get approved or not get approved, we don't really know. But if it does get approved, we view it as primarily competitive with T-VEC, which is the product that's on the market today.

Today that's also an oncolytic virus very similar to that product as well as products like Opdualag that are being recycled in the community right now. It has a lot of barriers like T-VEC did and honestly, when a company goes to launch a product they have to perform and we expect AMTAGVI is a much more compelling option I think for patients with its one-time profile and really fantastic efficacy and tons of real-world experience now. And so we think that'll be good.

And with the other company, Obsidian, that's a TIL competitor, I think people should look very hard and carefully at how far ahead Iovance is in this space and the infrastructure Iovance has and the strength that we have and the experience that we have in this area before they sort of just randomly assume that some other TIL company is going to come out of nowhere and somehow conquer the world here. So just bear that in mind that there's reality with all these things.

Many investors have visited us and see the scale of what we do and can see the power of what we do and how much hard work and experience went into this whole thing. It's not easy to recruit and there's a giant moat around Iovance that's I think very, very helpful for investors.

Rennie Benjamin, Analyst at Citizens

Great. Thanks for taking the questions.

Daniel, Operator

Thank you. Our next question comes from David Dye with UBS. Your line is open.

David Dye, Analyst at UBS

Great. Thanks for taking my questions. And also my congratulations on a great quarter. I have two questions on top of demand. Can you just talk more about the demand in various across different ATCs, do you see more demand concentrating in large ATCs or do you see increasing demand, smaller and newly activated ATCs that have a follow up?

Dan Kirby, Chief Commercial Officer

Thanks for the question. What we saw and what we are seeing right now is the ATCs that we originally opened in 2024 are starting to grow based on patient type and based on the information that we have that's been published recently. The ATCs that we onboarded last year, in 2025, those are continuing to accelerate. Some of them are hitting their stride, so to speak, and getting mature and treating their patients. And then in the first half of this year we've been opening ATCs at a pretty substantial pace and those are starting to contribute now. So we do see there's a few months between an ATC activation to then starting to treat patients and then comfort level goes up. So we are seeing growth across the different segments in regard to larger ATCs and whether they're contributing to more. I think our larger ATCs are still growing.

We still haven't had an ATC that we could say has reached complete peak because they keep looking for new patients and patient types in. So we are seeing across our subset of ATCs, all of them.

David Dye, Analyst at UBS

Great. Thanks for the color. And then on community ATCs which now represent roughly one third of the network, how does patient volume, referral behavior and reimbursement experience differ between community and academic centers?

Dan Kirby, Chief Commercial Officer

Great question. So for patient volume, they have the patients there and it's really not the number of patients, it's what time we're getting these patients. So as we said in the real world data that got published earlier this year is that patients that are on two or fewer lines of therapy have an over 50% response rate. Those patients reside primarily in the community setting before refer to the academics. So we see referral barriers go down. The volume of patients are there and they're there earlier.

We do see the community ATCs are having learning curves similar to what we saw in the academics. So again, it takes a little while for them to ramp up. They're doing so now. Most of the community ATCs we started to onboard in the second half of last year. I joined in the first half and that was one of the things that we said would be a focus. We come through on that focus and now a third of our ATCs and we do see that they can have a higher ceiling than the academics because again it's organic referral patterns within network which are much easier to maximize than referring to the academic centers.

David Dye, Analyst at UBS

Thank you so much.

Daniel, Operator

Thank you. Our next question comes from Colleen Kucey with Baird. Your line is open.

Nick, Analyst at Baird

Hey everyone, it's Nick on for Colleen. Thanks for taking the question. Congrats on the quarter. Just wondering if you could provide any color on how the conversion rate from referrals of treated patients has changed over the last few quarters. And then also just on just growth bottlenecks like patient identification, referrals, et cetera. What do you expect to be the biggest constraint on growth going forward? And just wondering if you could talk about how you plan on addressing that.

Dan Kirby, Chief Commercial Officer

Thank you. So as we look at this, the conversion to referrals, what we do see is earlier patients and earlier patients coming in. We're using that in both non-personal media as well as in face-to-face with our field forces to get that word out. So again, we are seeing the referrals come in earlier, which means we have time to treat the patients. So that is the change in the referral pattern. An earlier patient that gets into patient ID as well. We have gone after, I've mentioned in previous calls, the BRAF mutated patients because that is a very important patient type. 40% of our market that we were having trouble accessing before were getting tumor tissue earlier. That is helping us ID these patients earlier to get tissue so we can manufacture for infusion at the right time. And then as far as constraints with it, the constraints that we're working on is really more penetration into the larger community networks. And we see that as an opportunity. We've made a lot of strides over the last six to eight months with other entities, Florida cancers, et cetera, where we're getting the referral pattern up or we're looking to establish ATCs within their own networks.

We've got some up right now in those areas. We're looking to get more up. Fred, did you have anything to add?

Frederick G. Vogt, Interim CEO and General Counsel

No, Dan, I think that's pretty accurate.

Daniel, Operator

Thank you. This concludes the question-and-answer session. I would now like to turn it back to Fred Vogt for closing remarks.

Frederick G. Vogt, Interim CEO and General Counsel

Thank you for joining us. This was a record quarter for revenue, infusions, and margin. Our pipeline is advancing rapidly with new registrational trials, next-generation clinical programs, and new approvals. Outside the United States, we are energized by the growing number of patient stories that show the power of our TIL therapies.
