Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Thank you, Nicole. We are pleased to share that ZYNLONTA’s commercial performance in the second quarter of 2026 continued to be broadly in line with recent quarters. We remain confident in the role ZYNLONTA will continue to play as a differentiated single-agent treatment option for third-line plus DLBCL patients. Turning to our pipeline progress. As previously disclosed, we announced top-line results for LOTIS-5 in June. Based on this data, we held a pre-sBLA meeting with the FDA, and following the meeting, we are assessing the best regulatory path forward. Mohamed will share more details regarding the FDA feedback and our regulatory strategy. Further to this, the full LOTIS-5 data have now been submitted for presentation at ASH, and we are preparing to submit for publication with compendia submission to follow.

For LOTIS-7, we were pleased to complete enrollment of 100 patients at the selected dose level of ZYNLONTA plus glofitamab, as shared in June, and have submitted an abstract to ASH for presentation of the data, which we continue to believe demonstrates the most compelling combination data generated to date in second-line plus DLBCL, with a safety profile generally consistent with prior LOTIS-7 disclosures. With these data, we believe that ZYNLONTA plus glofitamab offers an opportunity to take a leading second-line position in the context of the evolving competitive landscape, solidifying ZYNLONTA as a foundational therapy in DLBCL. Beyond this, we are preparing to submit for publication of the LOTIS-7 data with compendia submission to follow. Simultaneously, we are exploring the potential regulatory pathway for this combination and expect to submit for breakthrough designation this year.

With respect to the multi-center investigator-initiated trials of ZYNLONTA in indolent lymphomas, updated marginal zone lymphoma data was submitted to ASH with publication and compendia submission to follow. Presentation of updated follicular lymphoma data is anticipated in the second quarter of 2027, with publication and compendia submission to follow. We also intend to assess potential regulatory pathways for these indolent lymphomas and expect to submit for a breakthrough designation for MZL. Moving now to corporate updates. We announced a strategic reorganization in June. As part of this, we implemented a reduction in our workforce of approximately 17%, as well as additional operational efficiencies, resulting in cost savings of approximately $10 million on an annualized basis.

As shared at that time, with these changes, we are resourced to deliver on our key clinical, regulatory, and manufacturing activities while maintaining the full externally facing footprint to support the continued commercialization of ZYNLONTA in the third-line plus DLBCL setting. Finally, we ended the second quarter of 2026 with a healthy cash balance of $219.1 million, maintaining our expected cash runway at least into 2028 and enabling us to deliver against our strategy. Now, I’d like to take a moment to remind everyone of our strategy to grow ZYNLONTA. Currently, ZYNLONTA plays a clear role in the third-line plus DLBCL setting. As monotherapy, ZYNLONTA has a well-established profile of rapid, deep, and durable efficacy, as well as manageable safety with simple and convenient administration. Since FDA accelerated approval in 2021, ZYNLONTA monotherapy has been used in treating approximately 5,000 patients in the U.S.

We believe this is just the starting point as we see the potential for ZYNLONTA to reach significantly more patients by expanding use into earlier lines of therapy in DLBCL and into indolent lymphomas. I would now like to turn the call over to Mohamed, our CMO, to share more on our pipeline.

Mohamed Zaki, Chief Medical Officer, ADC Therapeutics: Thank you, Ameet. I would now like to share more on our LOTIS-5 and LOTIS-7 studies as we continue to work towards expansion of ZYNLONTA in earlier lines of DLBCL. As a reminder, LOTIS-5 is our phase III confirmatory study of ZYNLONTA in combination with rituximab versus R-GemOx in patients with second-line DLBCL, which recently read out and met the primary endpoint of progression-free survival. As noted, we held a meeting with the FDA in early August to present and discuss the totality of the LOTIS-5 data, along with the potential regulatory pathway. During this meeting, the FDA noted substantial concerns regarding the benefit-risk or verification of taken benefit observed in LOTIS-5 trial. As such, the company is now assessing the regulatory path forward. We plan to provide an update on regulatory strategy and timing in the future. Beyond this, the data has been submitted to ASH.

We are simultaneously pursuing publication for LOTIS-5 and potential compendia inclusion starting in 2027. Turning now to LOTIS-7, our phase I-B trial combining ZYNLONTA with the highly effective bispecific glofitamab in second-line plus DLBCL patients. We recently announced completion of enrollment of 100 patients at the 150 microgram per kg dose. Of note, consistent with other glofitamab trials, the protocol for LOTIS-7 recommends prophylaxis, including vaccination for viral, fungal, and bacterial infections, including PJP and herpes virus, which was not part of the LOTIS-5 protocol. Here, we continue to be encouraged by the promising LOTIS-7 data shared to date, which we believe demonstrates the potential for ZYNLONTA plus glofitamab to be the best-in-class combination. With data on larger number of patients with longer follow-up has been submitted to ASH for presentation.

This data support the company’s belief that ZYNLONTA plus glofitamab demonstrates the most compelling combination data generated to date in second-line DLBCL with a safety profile generally consistent with prior LOTIS-7 disclosures. Separately, we are preparing for submission of the full LOTIS-7 data for publication and following that, plan to submit to compendia for potential inclusion starting in 2027. In addition, based on this potentially practice-changing LOTIS-7 data, the company plans to submit for breakthrough designation this year and is assessing a phase III trial for the combination of ZYNLONTA plus glofitamab. Moving forward, we plan to work closely with the FDA to determine the best path forward to achieve the full approval and advance the ZYNLONTA combinations into earlier lines of therapy in DLBCL.

In the meantime, we remain confident that ZYNLONTA will continue to play a meaningful role for patients with B-cell malignancies within its currently approved third-line plus DLBCL setting. With that, I would like to turn the call over to Pepe Carmona, our CFO.

Pepe Carmona, Chief Financial Officer, ADC Therapeutics: Thank you, Mohamed. On the financial front, ZYNLONTA net product revenues in the second quarter of 2026 were $18.6 million as compared to $18.1 million in the same quarter in 2025. Cost of product sales was $2.3 million and $6 million for the second quarter and six months ended June 30, 2026, as compared to $0.8 million and $2.9 million for the same periods in 2025. The increases compared to prior year are primarily driven by a change in focus of personnel from research and development clinical supply activities to commercial manufacturing activities. Total operating expenses were $44.7 million for the second quarter. On a non-GAAP basis, total adjusted operating expenses were $37.2 million for the quarter and were down by 22% over the prior year, primarily driven by lower R&D expenses.

As Ameet noted, we expect to save an additional $10 million on an annual basis as a result of the strategic reorganization we announced in June. On a GAAP basis, we reported a net loss of $16.6 million for the second quarter of 2026 as compared to a net loss of $56.6 million for the same period in 2025. The second quarter of 2026 included a one-time expense related to the strategic reorganization, while the year ago quarter included restructuring, impairment, and related costs from the June 2025 strategic reprioritization and restructuring plan. On a non-GAAP basis, the adjusted net loss was $16.3 million for the second quarter of 2026 as compared to a net loss of $28.7 million for the same period in 2025. The lower net loss on a non-GAAP basis was primarily due to lower operating expenses.

The year-over-year changes on a per-share basis were additionally impacted by the higher number of weighted average shares outstanding. You can find the reconciliation of GAAP to non-GAAP measures for the second quarter in the companion financial tables of the press release issued earlier today and in the appendix of this presentation. At the end of the second quarter, we had cash and cash equivalents of $219.1 million as compared to $231 million as of March 31, 2026, a change primarily driven by cash dues in operations. This provides us with an expected cash runway at least into 2028. With that, I will turn the call back over to Ameet. Ameet?

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Thank you, Pepe. To close, we are pleased by the commercial performance and the role that ZYNLONTA monotherapy continues to play in third-line-plus DLBCL. We look forward to presentation of data from LOTIS-5, LOTIS-7, and MZL before year-end, with publication and potential companion inclusion to follow. Following the FDA pre-sBLA meeting, we are assessing regulatory approaches to determine the best path forward for the LOTIS-5 trial. At the same time, we believe we have an opportunity for ZYNLONTA plus glofitamab to take a leading second-line position in DLBCL as a potential best-in-class bispecific combination and are actively assessing the potential regulatory path forward. Together, we anticipate we can grow ZYNLONTA beginning in 2027 as we work to make a meaningful difference in the lives of many more patients with B-cell malignancies. We can now open the line for questions. Operator?

Operator: Thank you. Ladies and gentlemen, we will now begin the question-and-answer session. Should you have a question, please press the star followed by the one on your touchtone phone. You will hear a prompt that your hand has been raised. Should you wish to decline from the polling process, please press the star followed by the two. If you are using a speakerphone, please set the handset before pressing any key. One moment, please, for your first question. Your first question comes from Eric Schmidt with Cantor. Please go ahead.

Eric Schmidt, Analyst, Cantor: Thanks for taking my question, and appreciate all the updates. Maybe just on the status of the current accelerated approval for ZYNLONTA, given the questions around risk-benefit from LOTIS-5, was there any FDA discussion of maintaining that accelerated approval status?

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah. A great question. First of all the discussions with the FDA were related only to the trial. All their comments were specific to the combination of ZYNLONTA plus rituximab on the trial. There was no feedback at all about the single agent. We remain confident that the monotherapy will stay on the market, will continue to have accelerated approval, and we’re committed to working with the FDA to make sure that we can satisfy the full approval either through LOTIS-5 or through another study.

Eric Schmidt, Analyst, Cantor: Thank you, Ameet. On LOTIS-7 and your characterization of the most recent efficacy data that you guys have seen as compelling and consistent in safety, have you essentially now seen the final ASH presentation, and do your comments pertain to that? In other words, do you know exactly what you will present, and is it consistent with that statement?

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah. We have already submitted the abstract for ASH, which contains obviously the vast majority of the 100 patients that we enrolled. The belief that I am sharing with you about the fact that we think we have very compelling efficacy and safety data is reflective of that ASH abstract, where obviously for disclosure reasons, you can imagine we do not want to share all the details, but we do believe that we have very compelling data both from an efficacy and a safety standpoint within the LOTIS-7 data that was submitted to ASH.

Eric Schmidt, Analyst, Cantor: Thank you. One more question, if I may, with regard to exploring a phase III pathway for the combination in LOTIS-7. Is that something you are exploring with Roche or by yourselves?

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah, I do not want to comment on that. Obviously, we have a great partnership with Roche, and they have given us great feedback throughout. What I would say is we have had lots of discussions, but also lots of thought, as you can imagine, even independent of the feedback from the FDA, about a potential phase III design because we know that this data is so compelling that there could be significant upside for the asset by potentially pursuing a phase III asset. So it is something we have been thinking about for a long time. The team has already been preparing on different design options that we do plan to file for breakthrough designation this year and to discuss with the FDA potential designs.

Eric Schmidt, Analyst, Cantor: Thank you for taking my questions.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah. Thank you, Eric.

Operator: Your next question comes from Michael Schmidt with Guggenheim Securities. Please go ahead.

Sarah, Analyst, Guggenheim Securities: Hey, this is Sarah on for Michael. Thanks so much for taking my question. Just wanted to follow on quickly on the phase III plans, whether you could give any color on sort of timeline for that now that it appears to be sort of more of the future-looking focus. Additionally, had a sort of

Ahmed, Analyst, H.C. Wainwright: A question on the LOTIS-5 data. I know you mentioned the 105-day period for monitoring adverse events after treatment. I was wondering if you could comment on the timing of the deaths.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: First of all, I just want to emphasize we have a positive study for LOTIS-5. We still are assessing possibilities to identify the best regulatory approach for LOTIS-5. Specifically, we are considering whether additional data, risk management options, or modifications to the potential label can address the updates in terms of LOTIS-5. We are doing that in parallel given that we have, we think, potentially practice-changing data on hand with the LOTIS-7. We are also, in parallel, going to file for breakthrough designation and explore a phase III approach there. It is too premature at this point, as you can imagine, while we are still gathering input from the medical community, and obviously have to collaborate with the FDA on a final design to talk about timing and cost. But I just want to reemphasize that those two things are going in parallel.

With regards to the 105-day safety window in terms of capturing AEs post-last dose, that is the same, by the way, in LOTIS-7 as well. One thing I want to emphasize is that, as Mohamed mentioned on the call, there was a big difference between LOTIS-5 and LOTIS-7, particularly with regards to prophylactic measures taken. In LOTIS-7, consistent with a lot of the other glofitamab trials that have been run, LOTIS-7 recommends prophylaxis, including vaccinations for viral, fungal, and bacterial infections. That was not part of the LOTIS-5 protocol. While the time period that we are capturing AEs is very similar, there was a pretty big difference in terms of prophylaxis and the protocol between five and seven.

Sarah, Analyst, Guggenheim Securities: Appreciate it. Thank you.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Thank you.

Operator: Your next question comes from Maulik Majmudar with Jefferies LLC. Please go ahead.

James, Analyst, Jefferies LLC: Hi. Good morning. This is James on for Mari. Thanks for taking our questions. Can you provide more detail on the type of grade 5 infections that were observed in LOTIS-5, and whether those events would have been expected to be mitigated by the prophylactic and vaccination strategies now incorporated into LOTIS-7? Did other infections occur that aren’t addressed by those vaccines? I have a follow-up after that.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah. The primary type of infections were bacterial, which is why we think that prophylaxis could play a role.

James, Analyst, Jefferies LLC: Got it. How do you think about the potential read-through from LOTIS-5 grade 5 signal to potential NCCN compendia inclusion and adoption of the ZYNLONTA plus glofitamab combination within the academic community? Could the LOTIS-5 impact the NCCN language, and could there be any safety monitoring requirements?

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah, I don’t think there will be any read-through in terms of LOTIS-7 compendia inclusion. Two very different studies, two different regimens. As I mentioned, the protocol is different, which we think can help to contribute to some of the safety differences. Just as a reminder, obviously, I cannot speak to the data we have on hand, but I can speak to the prior disclosure that we had. We had a very low percent of grade 5 events, approximately 4%, if you look at our last disclosure we had in December on the 49 patients that we recorded. So I do think there is a difference, and we do not think there would be a read-through to LOTIS-7 or to any potential NCCN or compendia inclusion.

James, Analyst, Jefferies LLC: Got it. Very helpful. Thank you.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Thank you.

Operator: You now have a question from Leonid Timashev with RBC Capital Markets. Please go ahead.

Josh, Analyst, RBC Capital Markets: Hi, guys. Josh on for Leo here. Thanks for taking my question. I was wondering whether or not the FDA in their feedback in response to the phase III round, do they provide any kind of indication of what an effective path forward might look like and what strategies you guys are thinking about at the time being? Thanks.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah, and I think typical in what you’d have in the pre-sBLA meeting, we share the data results and you’re aligning on the package for an sBLA submission. During that, as typical with any other pre-sBLA meeting, they share concerns that they have with the data. Right now we’re basically going through the feedback and assessing whether additional data, risk management options, or modifications to the potential label can help to address those update concerns. That’s the basis of which we’re evaluating our path forward for LOTIS-5.

Josh, Analyst, RBC Capital Markets: Thanks, guys.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Thank you.

Operator: As a reminder, if you wish to ask a question, please press star followed by the 1. Your next question comes from Rob Burns with H.C. Wainwright. Please go ahead.

Ahmed, Analyst, H.C. Wainwright: Hi, this is Ahmed on for Rob. Thank you for taking our questions. I was just wondering if you saw Q2 product revenue increase versus Q2 2025. I was wondering if you’ve seen any changes in patient starts or unit demand dosing or physician prescribing behaviors since LOTIS-5 disclosure. For my second question, I was wondering if in your conversations with the FDA, did they focus on the PFS in patients 75 or older, and if that would influence eligibility criteria or future label? Thank you.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah. With regards to sale, we haven’t seen any impact. If you look at the volume in Q2, very consistent with prior quarters. We don’t think that there will be. If you look overall over the past several quarters, the commercial performance of the monotherapy in the third line plus setting has been relatively consistent, and that’s because ZYNLONTA has an established place in that third line plus setting, and we don’t expect any impact on monotherapy sales. Remind me again, I’m sorry, your second question.

Ahmed, Analyst, H.C. Wainwright: No problem. I was wondering if

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Oh, just about patients 75 or older, right?

Ahmed, Analyst, H.C. Wainwright: Yes. Thank you.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Yeah. We don’t think it’ll have any impact on other studies. I think obviously older patients, specifically with infection, we think that the prophylaxis can play a role, and that’s also why the protocol, again, I want to stress for LOTIS-7 versus LOTIS-5 are quite different. So I think each study is on its own. I don’t think that there’s a read-through from this. We certainly learned a lot from LOTIS-5, and we’re happy with the differences in the protocol, of course, that we’re seeing in LOTIS-7. So we don’t see any read-through from LOTIS-5 to either the current indication or other potential combinations.

Ahmed, Analyst, H.C. Wainwright: Thank you.

Operator: There are no further questions at this time, so I will now turn the call over to Ameet Mallik for closing remarks. Please continue.

Ameet Mallik, Chief Executive Officer, ADC Therapeutics: Well, thank you all for joining the call today and for your continued support. We look forward to keeping you updated on our progress. Operator, you may now end the call.

Operator: Ladies and gentlemen, this concludes today’s conference call. Thank you for your participation. You may now disconnect.
