Delcath Systems (NASDAQ:DCTH) is a specialty pharmaceutical and medical technology company focused on the development and commercialization of its proprietary Hepatic CHEMOSAT® Delivery System, designed to deliver high-dose chemotherapeutic agents directly to the liver while minimizing systemic exposure. The company’s core technology performs isolated hepatic perfusion, enabling oncologists to administer concentrated melphalan to patients with primary and metastatic liver tumors, including those arising from ocular melanoma. Delcath’s approach aims to improve tumor response rates and extend progression-free survival for patients with limited treatment options.

The Hepatic CHEMOSAT® Delivery System comprises specialized catheters, an extracorporeal filtration system and an isolation balloon that together isolate the liver’s vasculature, deliver high-dose chemotherapy and filter the returned blood before it reenters the patient’s systemic circulation. Delcath has achieved CE Mark approval in Europe for the treatment of unresectable liver tumors and is advancing its clinical development program in the United States, where it has completed pivotal trials assessing safety and efficacy in patients with ocular melanoma metastases in the liver. The company also continues to explore expanded indications and next-generation applications of its chemosaturation platform.

Headquartered in New York, Delcath Systems operates in key oncology markets across North America and Europe, collaborating with leading cancer centers and interventional radiology departments. The organization is guided by a management team and board of directors with experience in medical device commercialization, oncology drug development and regulatory affairs. Delcath remains committed to advancing targeted regional therapies that address unmet needs in the treatment of liver tumors and improving patient outcomes through innovation and rigorous clinical investigation.

Delcath Systems Q2 2026 Earnings Call Transcript

Key Takeaways

• Positive Sentiment: HEPZATO revenue and guidance increased: Second-quarter HEPZATO KIT revenue reached $27.1 million, up 21% year over year, while volume rose 30% despite the impact of 340B pricing. Delcath raised full-year 2026 revenue guidance to $104 million-$108 million and expects positive adjusted EBITDA.
• Positive Sentiment: Commercial footprint continued to expand: The company activated two treatment centers in the quarter, reaching 31, and remains confident it can reach approximately 37 centers by year-end. New patient starts averaged about 0.5 per site per month, with leading NCI- and NCCN-affiliated institutions making up a substantial portion of the network.
• Neutral Sentiment: Expansion into additional cancers is progressing but remains early: Phase II studies in third-line liver-dominant colorectal cancer and HER2-negative metastatic breast cancer are adding sites and improving enrollment, while an interim colorectal readout is expected in late 2027. Management acknowledged that enrollment has been slower than initially expected because of the complexity of coordinating oncology and interventional radiology teams.
• Negative Sentiment: Profitability was supported by strong gross margins, but investment and pricing pressures remain: Second-quarter gross margin improved to 90%, although full-year guidance is 86%-89% due partly to anticipated manufacturing costs. Research and development and selling, general and administrative expenses increased year over year, while adjusted EBITDA declined to $7.6 million from $9.8 million.

[Gerard Michel, CEO at Delcath Systems]

Thank you for joining us today. Now well into our third year of commercial launch, we continue to deliver revenue growth and operate as a profitable business, supported by a platform with the potential to address larger patient populations well beyond metastatic uveal melanoma. We delivered a strong Q2, driven by $27.1 million in HEPZATO KIT revenue, up 21% over the Q2 of 2025. A significant achievement given the introduction of 340B pricing in July of 2025. We activated two new treatment centers, bringing our total to 31, and sustained a healthy flow of new patients into our existing sites. Our commercial execution in metastatic uveal melanoma is now self-funding the investment needed to extend our liver-directed platform into other cancers where the liver is a dominant site of disease.

[Gerard Michel, CEO at Delcath Systems]

We remain on track to activate approximately six additional centers by year-end, which would bring us to 37 active centers. We are not simply opening more centers; we are opening the right centers. Most of our targets are part of one of two overlapping groups of institutions. The first is National Comprehensive Cancer Network member institutions, or NCCN, an alliance of 34 leading cancer centers that help define oncology standards of care. The second is the National Cancer Institute's Comprehensive Care Centers, 58 institutions federally designated for excellence in cancer research, clinical trials, and multidisciplinary patient care. Today, approximately 80% of our active treatment centers hold NCI comprehensive designation. Nationally, we are now represented at 41% of the 58 NCI comprehensive care centers and approximately half of the 34 NCCN member institutions. Our 2026 activations continued that pattern.

[Gerard Michel, CEO at Delcath Systems]

This year, we added MD Anderson, UT Southwestern, Mayo Clinic Scottsdale, the OHSU Knight Cancer Institute, and the Herbert Irving Comprehensive Cancer Center at Columbia, all NCI comprehensive cancer centers. With MD Anderson, UT Southwestern, and Mayo Clinic also NCCN member institutions. These are among the nation's leading referral destinations for complex oncology care and liver-directed therapy. By adding institutions with this level of academic influence and referral reach, we are building a network that supports both near-term growth and long-term leadership in metastatic uveal melanoma and in the additional indications we intend to pursue. Beyond activating new centers, we are focused on increasing physician awareness and consideration of PHP for appropriate patients through targeted medical education, peer-to-peer engagement, and continued evidence generation. New patient starts remained solid in the Q2, averaging approximately 0.5 new patients per site per month.

[Gerard Michel, CEO at Delcath Systems]

Because patients typically receive a series of HEPZATO treatments over up to three quarters, Q2 starts generate volume that flows into the back half of the year and support our full year revenue outlook. The data from the CHOPIN trial, a randomized phase II study published in "The Lancet Oncology" earlier this year, continues to accelerate broader adoption of combination approaches at leading centers. At ASCO this year, investigators from Moffitt Cancer Center presented a trials in progress abstract describing an ongoing phase II study of HEPZATO followed by tebentafusp in HLA-A2 positive patients with metastatic uveal melanoma. We believe this and future planned combination therapy trials will be critical to moving HEPZATO more consistently to a co-first-line setting.

[Gerard Michel, CEO at Delcath Systems]

Turning to clinical development beyond metastatic uveal melanoma, we remain confident in HEPZATO KIT's potential in other liver-dominant cancers, we continue to work with investigators to generate supporting data. At ESMO Breast Cancer in May 2026, independent investigators presented a retrospective analysis of 15 heavily pretreated patients with liver-dominant metastatic breast cancer treated with percutaneous hepatic perfusion. Nine of the 15 patients showed a hepatic partial response, supporting further evaluation of this approach in that setting. Turning to our sponsored trials. In our sponsored phase II trial in metastatic colorectal cancer, we now have 13 centers actively screening. Consistent with the acceleration we anticipated on our last call, recruitment has improved as we have added sites and applied specialized training and streamlined onboarding. We estimate that approximately 6,000-10,000 U.S. patients annually have liver-dominant disease in the third-line setting.

[Gerard Michel, CEO at Delcath Systems]

In HER2-negative metastatic breast cancer, we recently dosed the first patient at the European Institute of Oncology in Milan. Six sites are activated in screening with additional sites in the activation process. We estimate a similar-sized addressable population in this indication. Beyond these two programs, we continue to evaluate additional liver-dominant indications through our scientific advisory board and physician feedback. We are preparing for pre-IND meetings with the FDA later this year to discuss new potential indications. Based on our H1 results and trends early in the Q3, we are raising our full-year revenue guidance. Sandra will take you through the numbers and our updated outlook. Sandra?

[Sandra Pennell, CFO at Delcath Systems]

Thank you, Gerard. Total revenue in the Q2 of 2026 was $29.1 million, compared with $24.2 million in the Q2 of 2025. This includes $27.1 million of HEPZATO KIT revenue and $2 million of CHEMOSAT revenue. This represents 17% sequential HEPZATO volume growth over the Q1 and 30% volume growth versus the same period in 2025. Turning to 2026 guidance, we are increasing our full-year revenue guidance to range from $104 million-$108 million, which reflects at least a 28% growth in HEPZATO KIT volume over 2025. Our decision to raise guidance is driven primarily by H1 performance, particularly the pace of new patient starts. We've also modestly reduced the seasonal step-down we had assumed for the Q3 and Q4.

[Sandra Pennell, CFO at Delcath Systems]

A part of last year's seasonality came from centers operating with a single REMS certified treatment team, where staff absences translated directly into lost treatment capacity. We have since worked with centers to train backup teams, including some of our highest volume sites, which should ease that constraint. Enrollment in ongoing clinical trials during 2025 reduced the number of patients available for our treatment. Gross margin for the quarter was 90%, compared to 86% in the Q2 of 2025. We are guiding to full-year 2026 gross margin between 86%-89%, we also expect to report positive adjusted EBITDA for the full year. Research and development expense in the Q2 was $10.4 million, compared to $6.9 million in the prior year quarter, driven primarily by continued investment in our clinical organization and ongoing phase II trials.

[Sandra Pennell, CFO at Delcath Systems]

Selling, general, and administrative expense in the Q2 was $13.4 million, compared to $11.4 million in the prior year quarter, reflecting our investment into continued commercial expansion and increasing marketing activities. Net income for the Q2 in both 2026 and 2025 was $2.7 million. On a non-GAAP basis, adjusted EBITDA for the quarter was $7.6 million compared to $9.8 million in the Q2 of 2025. We ended the quarter with cash and investments of $95.9 million. Cash provided by operations was $5.7 million in the quarter, and we purchased a small amount of common shares in the Q2 under the company's approved $25 million share buyback program. To date, we have purchased approximately $9 million worth of common shares. I want to thank you all for participating today, and I'll ask the operator to open the lines for Q&A. Thank you.

[Operator]

Thank you. Ladies and gentlemen, we now begin the question-and-answer session. If you'd like to ask a question, please press star followed by number one on your telephone keypad. If your question has been answered and you would like to withdraw from the queue, please press star followed by the number two. If you're using a speakerphone, please lift your hand before pressing any keys. One moment, please, while we compile the roster. Your first question comes from Marie Thibault with Bancorp BTIG. Please go ahead.

[Marie Thibault, Analyst at BTIG]

Hi. Thank you for taking the questions. I wanted to ask a question here just sort of on the referral pathway and some of the efforts I know that you've been making on the commercial side. Wanted to understand how the referral network efforts have been progressing. I know you've been working on it for a few quarters. Are there ways to sort of describe the outreach that you've been making to the medical oncologists that is translating into incremental new patient starts? Second, I'll just ask my follow-up here. I wanted to follow-up, I think there was an effort to try to mitigate summer seasonality, get second treatment teams trained at various centers. Just an update on how that has been progressing as well. Thanks for taking the questions.

[Gerard Michel, CEO at Delcath Systems]

Sure, Marie. Good to hear from you. In terms of the referral network, I would say about a third of the referral network is a static network, and that is within the institutions we are currently part of, any oncology networks that are part of that. There, we know who the oncologists are. They have a meaningful number of patients. Meaningful could be two, three, four, but on a relatively consistent basis. The other part of the referral network, and probably should be kind of called a just-in-time referral, are the many, many doctors who just get one patient. Now, many of those patients eventually make their way to one of our treating sites or one of our targeted sites that will open in the next one month to two years as we continue to expand. Many of those are not.

[Gerard Michel, CEO at Delcath Systems]

What we have to do is find them in real time if we want to get them first line, if we don't want to lose patients who progress too quickly. Our efforts there right now are multifaceted. Can you hear me? Can everyone hear me?

[Marie Thibault, Analyst at BTIG]

We lost you for a while, Gerard. We lost you for a minute.

[Gerard Michel, CEO at Delcath Systems]

Okay. All right. Where did you lose me? The perils of cell phones.

[Marie Thibault, Analyst at BTIG]

We were just past kind of talking about those folks that only see one patient. We got a little bit past that.

[Gerard Michel, CEO at Delcath Systems]

What we need to do is get a just-in-time network is the kind of the term I'm using internally with the team. Right now we're using claims data. That lags, but we generally know patients who've been recently diagnosed. Recently could be anywhere from one month-six months, given claims lags. We try to get in front of those doctors a number of different ways. We'd like to do better than that. We're investigating the use of other forms of data that are refreshed more frequently. That's not in place yet, but we will get it in place. We recognize that we have a higher hill to climb in terms of execution than something like an Immunocore, in that community oncologists can't use our product. We have definitive plan. We are definitely working that right now.

[Gerard Michel, CEO at Delcath Systems]

We are actively finding patients who've had a recent biopsy and stuff, and we're working to improve that over time. It is and will be a core part of our strategy. Your second question was about training additional docs at centers.

[Marie Thibault, Analyst at BTIG]

Yes.

[Gerard Michel, CEO at Delcath Systems]

We've had several centers that I think our efforts led to backup teams. At least one or more of those are very high-volume centers that it was critical to do that in. I wouldn't say that we have backup teams everywhere we would like to. A meaningful percentage of our volume now is covered by centers with backup teams.

[Marie Thibault, Analyst at BTIG]

Thank you so much.

[Operator]

Thank you. Your next question comes from John Newman with Canaccord Genuity. Please go ahead.

[John Newman, Analyst at Canaccord Genuity]

Hey, guys. Thanks for taking my question. Really nice execution on the quarter. I have a couple of questions here. I'm curious as to how much of the increased guidance for the year could be related to better uptake excuse me, due to the CHOPIN data. Also wondering if you can discuss your enrollment expectations for both colorectal and the breast cancer studies. And I'm wondering with those two studies, if you are able to utilize overlap between existing centers that are already using HEPZATO for liver mets due to uveal melanoma. Thank you.

[Gerard Michel, CEO at Delcath Systems]

All right. First part of your question, in terms of how much of the increase is from CHOPIN, it's all anecdotal. The data, the claims data's rather thin. For some reason, our claims data comes in very slow relative to other treatments. Our anecdotal experience is that more and more of these patients are getting combination therapy, and that's undoubtedly a result of the CHOPIN data. In terms of site recruitment, which I think was your third question, we're not going to give guidance on that. I think the only guidance we're going to give is that we expect an interim readout for colorectal sometime late next year, and we're not providing guidance on breast. We are encouraged by both an uptick in both trials in terms of site activation enrollment. There was a second question there, embarrassed to say I lost it.

[Gerard Michel, CEO at Delcath Systems]

Could you remind me, John, what it was?

[John Newman, Analyst at Canaccord Genuity]

Sure. Just curious if you're able to utilize existing centers that are using HEPZATO in terms of also signing them up for enrollment with breast and colorectal cancer.

[Gerard Michel, CEO at Delcath Systems]

Yeah, I would say the majority of centers in the U.S. Already REMS activated for MUM. In Europe, it's a lower percentage. We're actually activating some new centers. Can you guys hear me? I got another message that audio dropped.

[Kevin Muir, CCO at Delcath Systems]

We can hear you.

[Gerard Michel, CEO at Delcath Systems]

Okay. All right. We also have a number of, in Europe, it's a smaller number of percentage of centers that were MUM centers. I'd say, maybe 60/40 existing centers and new centers in the trial.

[John Newman, Analyst at Canaccord Genuity]

Okay, great. Thank you.

[Operator]

Thank you. Your next question comes from Chase Knickerbocker with Craig-Hallum. Please go ahead.

[Chase Knickerbocker, Analyst at Craig-Hallum]

Good morning. Congrats on a really nice quarter, and thanks for taking the questions. Just wanted to dig in a little bit more on the implied H2 in your guidance. If we look at that, it assumes a pretty meaningful slowdown still. With that in mind, can you just maybe talk through exactly when you started seeing that softness in new patient starts last year? What you've seen so far through July, early August. Have you seen any green shoots from some of the programs that you put in place to try to train additional treatment teams, et cetera?

[Gerard Michel, CEO at Delcath Systems]

Without going into specific numbers, I will say, Chase, that the bulk of our increase in guidance is due to an impressive H1 of the year. We have tempered the downturn we expect in the H2, partly due to, frankly, less demand from clinical trials. The second part is really just a two-week lead. We only have a two to three-week vision idea of what's going to happen going forward. It looks reasonably strong, so we've tempered the overall seasonality as well. I would say the bulk of our increase in guidance is based on our performance in the H1 of the year. As you well know, new patient starts drive business over two-three more quarters.

[Chase Knickerbocker, Analyst at Craig-Hallum]

Fair to say that we haven't seen, to-date, the same kind of softness in new patient starts, at least yet. Just second follow-up would just be the visibility that you have the center adds in the back half of the year here, and how you're thinking about that year-end target.

[Gerard Michel, CEO at Delcath Systems]

Yeah. I'll ask Kevin in a moment to comment on how we feel about the additional six centers. In terms of it's fair to say we haven't seen the softness yet, this is about when we saw it last year. We kind of two-week look forward at this point, it dropped dramatically. No, we haven't seen that yet. Again, I think I want to caution listeners that we don't have a very long forward-looking visibility into these things. It's about two-three weeks. This time last year, we saw some softness in that two-to-three week period. We're not seeing that quite yet. That's only two to three weeks. Kevin?

[Kevin Muir, CCO at Delcath Systems]

Yes, thanks, Gerard, and thanks for the question, Chase. We are looking kind of strong for the number of new sites that we're bringing on. We kind of get them in bits and starts when training is completed. We have a number of sites that are in the queue to get our preceptorship and proctorship, and it's just a matter of time until they open for the remainder of the year. I feel very strong that we can attain toward the goal of 37.

[Gerard Michel, CEO at Delcath Systems]

Yeah, our goal of 37, my friend. I also would say, I think we have at least one patient scheduled, maybe two right now, and then one more looking for patients. Patients can get scheduled, that one I mentioned. These are on the cusp, and what we've found is the on-the-cusp ones can go in weeks, they can go in months. There's a healthy on-deck circle here. The 37 is well within our reach. Fingers crossed a bit, as we know it's episodic, but it's not a soft pipeline.

[Chase Knickerbocker, Analyst at Craig-Hallum]

Helpful color, guys. Thank you.

[Operator]

Thank you. Your next question comes from Sam Pankula, RM account with H.C. Wainwright. Please go ahead.

[R K, Analyst at H.C. Wainwright]

Thank you. This is R K from H.C. Wainwright. Good morning, Gerard and Sandra.

[Gerard Michel, CEO at Delcath Systems]

Morning.

[R K, Analyst at H.C. Wainwright]

A couple of quick questions here. I'm trying to bridge the gap between the 30% HEPZATO volume growth and the 20-some% revenue growth. How much of that gap is from 340B or Medicaid or just the site mix? The second question is on the gross margin. You exited last quarter with 90%.

[R K, Analyst at H.C. Wainwright]

Your guidance asks for a little bit lower than that for the full year. Is that basically coming from the top line, or is there something else that's going on?

[Gerard Michel, CEO at Delcath Systems]

Sandra?

[Sandra Pennell, CFO at Delcath Systems]

Yes, I can answer both questions with regard to the Q2 volume as well as the revenue from prior years. Reminder that 340B pricing, which reduced our effective ASP from about $185 down to about $170,000, $173,000 per kit this year versus what we recognized last year. Even though revenue is only up 21%, it's actually representative of 30% volume. 100% of that difference between those two figures is due to 340B. With regards to gross margin, yes, we had a great quarter in Q2, recognizing 90%, which is up from 86% a year ago and is above our original guidance of 85%-87% for the full year. The Q2 improvement reflects better overhead absorption, favorable manufacturing performance, and obviously increased HEPZATO volume. As we go into the remainder of the year, we do have to be a bit conservative around additional manufacturing costs.

[Sandra Pennell, CFO at Delcath Systems]

The full year is 86%-89%. We may see a quarter that dips a little bit below that 90% and one that hits 90% again. That's our current guide.

[R K, Analyst at H.C. Wainwright]

Thank you. Thank you, Sandra, for taking the questions.

[Sandra Pennell, CFO at Delcath Systems]

Thank you.

[Operator]

Thank you. Your next question comes from Yale Jen with Laidlaw & Company. Please go ahead.

[Yale Jen, Analyst at Laidlaw & Company]

Good morning. Thanks for taking questions, and congrats on a good quarter performance. We have two here. The first one is that I noticed your recent deck in terms of the type of cancer that metastasized to liver, you have eight of them. Just curious initially why you choose the breast cancer and the CRC, given they are not necessarily the highest volume or other factors. Any thoughts of that when you made that decision? I have a follow-up.

[Gerard Michel, CEO at Delcath Systems]

That's a great question. We started the conversations as to those two trials probably a good two years ago. For CRC, there's a large amount of liver-dominant cancer. It's probably the largest outside of primary. The setting we chose, third line, is not the largest. It's actually quite a bit cut down from the overall population of patients with liver-dominant cancer, the CRC patients. The reason we chose that, frankly, was when oncologists and, to a lesser extent, IRs who are fairly unfamiliar with our therapy, when we were having conversations about where to start, that's where we got traction. And it was largely driven by doc's willingness to participate. Now, I don't want people to think, "Well, that's a big negative." This is a very novel procedure.

[Gerard Michel, CEO at Delcath Systems]

Oncologists generally prefer systemics, I think the data as we generate it will bear out, the oncologists will change their perception, first in terms of trials they want to participate in, then eventually, obviously, actual commercial clinical usage. In terms of breast cancer, that one is a bit less, admittedly, there was real interest in oncologists in terms of participating in that trial. It's been slow to enroll and get started, there were a couple of key KOLs who thought there was a real need here. Various types of breast cancer tumors generally react well to chemotherapy, so that was one reason a number of docs were excited. These were the starting sets where we could get traction with oncologists being interested. Who knows? If we started now with the level of understanding we have out there, would it be a different set?

[Gerard Michel, CEO at Delcath Systems]

We had to start somewhere. I think these are meaningful markets for us, there's a real unmet need in these settings. We'll add more, some orphan type indications and some much larger indications going forward.

[Yale Jen, Analyst at Laidlaw & Company]

Okay, great. That's very helpful. Maybe just to tack on that from the similar themes, which is the, with the current patient enrollment of those two trials, are they within your expectation or you have different sorts of hope in terms of the pace and other factors? Thanks.

[Gerard Michel, CEO at Delcath Systems]

Definitely lower than our expectations. There are a number of reasons for that. I think one not so obvious reason is that just as we had to get sites REMS certified and up and running, we had that issue with new centers. We also had to educate the clinical trial teams, we found that getting the IR teams, which are less set up for clinical trials, to work with the oncology teams, which are very familiar with trials, they're not familiar with this type of therapy, getting those teams to work together with the new patient flow, the type of data we need to gather in the IR suite, it was very new to them. Quite frankly, a number of centers that we thought would quickly activate, enroll, we got the disparate teams together, it became an issue.

[Gerard Michel, CEO at Delcath Systems]

With the dimension of change in training, we did not anticipate would be a problem in the clinical trial setting. Just as in the commercial setting, there was a hill to climb that we kind of understood we'd have to do when we started. It was bigger hill than we thought. Finally found the same thing in the clinical trial. Getting the clinical trial teams to work together in this type of trial was a problem. We lost some centers because of it, undoubtedly. The bigger issue was just centers taking a while to get up and running. Again, interesting product, different type of product. We're working through the issues just as we have commercially. We're going to work through the issues on the clinical side as well.

[Yale Jen, Analyst at Laidlaw & Company]

Okay, great. This is very helpful, and certainly congrats on all the progress, and best of luck to you guys.

[Operator]

Thank you. There are no further questions on the phone line. I will turn the call back to Mr. Michel for some closing remarks.

[Gerard Michel, CEO at Delcath Systems]

Okay. Just want to thank everyone for their support, both the investors as well as the internal team here at Delcath. We're getting a lot done, and it wouldn't be if it wasn't for the employees of the company who are very dedicated to move things forward for patients and to earn the trust of the investors. Thank you very much for your time, and have a great day.
