Corey Fishman - Chief Executive Officer - (00:04:46)

Thank you, Kevin. Welcome to everyone and thank you for joining us today. We're excited to be talking with you today and especially looking forward to sharing information about the early stages of the Orlinva commercialization. Just to remind you, we launched Orlinva into the market on August 20th of this year. Now I'd like to turn the call over to our Chief Commercial Officer, Christine Coyne.

Christine Coyne - Chief Commercial Officer - (00:05:12)

Thank you, Corey, and good morning to everyone. As with nearly every new product launch, changing behaviors and old habits is paramount, particularly in a category where prescribing habits have been ingrained for decades due to lack of innovation and limited new branded options. Changing healthcare provider behavior involves frequent office visits and getting time with those prescribers and their office staff. Our field team has been calling on our providers and ensuring they remember that there is now a better way to help treat their uncomplicated urinary tract infection patients with Orlimba. As with any promotion, message retention and behavior change increases over time and with frequency. That is our current focus with our customers. Each week this improves. Having said that, we made steady progress in educating providers about Orlimba and driving early Orlimba use among patients suffering from uncomplicated urinary tract infections. Especially in the most recent weeks, our momentum with customers has been growing consistently. Through November 12, we generated more than two hundred and eighty prescriptions, which were driven by more than 100 unique prescribers. Nearly half of those prescribers have broadened their experience by prescribing Orlimba to more than one patient. This is an important signal of both physician and patient experience with Orlimba. As physician comfort with Orlimba continues to grow, we have seen a number of these physicians broadening out their use, especially in the most recent weeks. Another important indicator which we follow closely is the fill rate of your Limba prescriptions through our specialty pharmacy partner. This step in the process has a few parts to it with new product introductions. In many instances, payers have yet to make their decisions on formulary inclusion, which provides coverage for patients. That said, there's usually a path forward to help these insured patients get their prescription, and we are working our way through all of this now, as with a large proportion of launches, once payer decisions are made and coverage and access are achieved, this fill rate should improve. However, even during this period of launch while awaiting payer coverage, we have found that approximately 40% of your Limba prescriptions have gone through these payer approval processes and have been filled, which aligns with our expectations. As for the patient's out of pocket exposure, we have a copay support program that helps defray the cost from for appropriate commercial patients. While this may be of help to some patients, it is our intention to work with insurance carriers, including Medicare plans to gain access to and coverage of Orlinba to help optimize this adjudication process and patient out of pocket exposure over time. We will discuss more on our progress here in just a moment. With your Limba promotion gaining momentum each week we have received a number of inquiries from physicians interested in obtaining Orlimba to whom the specialty pharmacy distribution is outside of their business practice model. Given the number and frequency of inquiries such as these, we have been working with two of the most widely used specialty distributors, McKesson and Sancora, to tuck into these particular physicians ways of practicing. This specialty distribution model allows these physicians to purchase OR LIMBA through their preferred distributor and it supports how they like to practice at this time. We have already shipped or Limba to McKesson and we will be shipping OR Limba to Sancora shortly. Customer feedback and insights continue to be received as our efforts expand weekly to a wider set of healthcare providers and as utilization deepens with those providers who have already prescribed Orlimba. Some of the important learnings include Physicians welcomed Orlinva as a new alternative for physicians to help treat their uncomplicated urinary tract infection patients effectively. But especially where resistance is a challenge, physicians can clearly see a place for Orlimba to help them break the cycle of patients being treated with multiple antibiotics which have been resistant OR Limba provides physicians with a new option. Additionally, our customers have reported the importance of Orlimba helping them to keep their patients out of the hospital. Being able to treat with a new oral option that helps keep their patients at home has been reported of great importance by our physicians. Also, physicians clinical experience with Orlinva and their patients has and as expected. Lastly, customer feedback coming from our recent presence at the Infectious Disease Week Conference which was held last month in Atlanta. Our efforts included a poster session. A Learning Lab presentation confirmed very high interest from both key thought leaders and large infectious disease group practices with requests for follow up discussions Overall, we are pleased with the steady progress we have made, particularly given the modest commercial infrastructure we currently have in place. The field team continues working with healthcare providers as trial and adoption of ORLIMBA continues. Now, regarding our field operations, we continually monitor an array of performance metrics to help us capitalize on opportunities quickly as we discover them, as well as optimize areas where effectiveness needs to be improved based on these diagnostics. We reduced the in person field team to 10 representatives from our original plan of 20 and are in the process of augmenting our efforts with both in person and virtual SALS representatives. Once fully in place, the combination of the existing resources and our new supplemental resources should provide Iterum the equivalent coverage in at least the initial 20 target geographies, if not more, and it will be done with greater efficiency. Now I'd like to spend a few moments and talk about managed care and market access. Overall, Iterum's coverage discussions are advancing well with positive feedback from both pharmacy benefit managers and health plans across both their commercial and Medicare Part D formularies. Iterum's national account managers continue to engage strategically with key stakeholders across the U.S. payer landscape or LIMBA's differentiated value proposition and ongoing formulary discussions with state, regional and national health plans, including the three largest pharmacy benefit managers, have been met with strong interest and positive feedback. Today we are pleased to announce that we have a signed rebate agreement with one of the top three Medicare Part D pharmacy benefit managers. This agreement enables or LIMBA to be added to their Medicare Advantage prescription drug Plan and Medicare Prescription Drug Plan formularies for coverage beginning in 2026 or 27 depending upon the individual plan structures. Also, ITRHAM has been invited to bid for formulary inclusion across commercial Medicare Part D and government segments managed by these pharmacy benefit managers. With submissions now complete, we are aiming to secure long term formulary positioning later this year and into Q1 2026. Orlimba's access continues to grow with or without prior authorization or medical exception pathways. Coverage now reaches 16% of of insured lives with increasing adoption by employer groups and payer formularies integrating our LIMBA into their standard benefit designs. We expect additional decisions in the coming quarters and continue to see an increase in patient access and early prescription growth reinforcing our confidence in the commercial trajectory. Now I'd like to turn it back over to Corey. Thank you.

Corey Fishman - Chief Executive Officer - (00:14:52)

Thanks for the update on our Limbus commercialization. Christine. I'll make a few additional remarks with regard to our patent estate. We continue to expand our coverage. We've been granted a patent in China that covers a combination of sulu penamethadroxal, probenecid and valproic acid for treating specified diseases. This patent is expected to expire in March 2041, absent any patent term extensions. We have also been granted a patent in Mexico that covers a bilayer tablet comprising sulopenem etadroxil and probenecid methods of preparing the tablet and the bilayer tablet for use in treating specified diseases. This patent is projected to expire in December 2039, absent any patent term extensions. I now would like to provide some financial guidance. As you may have seen in our financial statements, Iterum generated net product sales of $400,000 in the third quarter, which included some stocking at our specialty pharmacy. We expect modest sales in the fourth quarter this year as well as we look ahead to 2026 with our existing field organization continuing to call on their targets. The additional resources we plan to add that Christine mentioned earlier, as well as obtaining coverage in key pharmacy benefit manager insurance plans, we currently expect our full year 2026 net product revenue to be in a range between 5 million and $15 million. It's important to note that that if Iterum were to achieve this revenue guidance for next year, it will have done so with a modest field organization relative to other antibiotic launches in the us. As it relates to total operating expenses, we currently estimate these will be between 25 and 30 million dollars for the full year 2026. Our existing cash and cash equivalents provides an operating Runway into the second quarter of 2026. In order to continue commercialization throughout 2026, we will need to raise more capital. We have and will continue to discuss potential financing opportunities with available sources of capital, including non dilutive funding options, but to date have yet to secure a viable transaction. As such, we will likely look to obtain approval from our shareholders at an extraordinary general meeting over the coming months to grant our Board of Directors authority to issue additional shares. If we are successful in getting this approval and raising incremental capital, we would use those funds to continue the ongoing Orlinva commercialization as well as potentially putting additional resources against high value territories or expand into other highly valuable territories not yet tapped by us or both. Of course, our goal over the next couple of years is to generate revenue in excess of the amount of expenses we have and be self funding. In summary, the feedback from physicians, payers and patients has been very good for Orlinva and we are encouraged by the results we've achieved to date if we're successful in raising additional capital, we believe we can continue to drive revenue growth and position Orlinva for broader market adoption. Now I'll turn the call over to Judy Matthews for a financial update.

Judy Matthews - Chief Financial Officer - (00:18:52)

Thanks, Corey. Net Product revenues were 0.4 million in. The third quarter of 2025 with the launch of Orleans in the United States in August 2025 and included initial stocking at our specialty pharmacies locations serving our targeted territories. Total operating expenses were $8.1 million in the third quarter 2025 compared to 4.9 million in the third quarter 2024. Operating expenses include cost of sales, the amortization of an intangible asset, research and development expenses, and selling, general and administrative expenses. Cost of sales expense for the third quarter 2025 was.02 million and primarily consisted of royalty payments pursuant to our license agreement with Pfizer. Note that prior to approval in October 2024, costs incurred for the manufacturer of Orlimba were recorded as research and development expenses. Amortization of intangible asset for the third quarter 2025 was 0.3 million and related to the finite lived intangible asset recognized in relation to the regulatory milestone payments payable to Pfizer upon approval or limba by the FDA. R&D costs were $1.3 million for the third quarter compared to $3.1 million for the same period in 2024. The primary driver of the decrease in R and D expense for the third quarter was lower. Chemistry, manufacturing and control or CNC related expenses following approval costs incurred for the manufacturer of Orlimba have been capitalized to inventory. SG&A costs were $6.5 million for the third quarter compared to SGA costs of $1.8 million for the same period in 2024. The primary driver of the increase in SGA expense for the third quarter was commercialization activities associated with the August 2025 launch of Orlimba in the United States. Our net loss on a US GAAP. Basis was $9 million for the third quarter of 2025 compared to a net loss of $6.1 million for the third quarter of 2024. On a non GAAP basis, which excludes certain non cash adjustments, our net loss of $7.3 million in the third quarter 2025 compared to our non GAAP net loss of $4.8 million in the third quarter 2024. The $2.5 million increase in our non GAAP net loss for the third quarter was primarily utilization activities for Orlimba, partially offset by lower CMC related expenses. At the end of September, we had cash and cash equivalents of $11 million. Based on our current operating plan, which includes our forecasted sales, we expect other cash and cash equivalents, together with $2.6 million of net proceeds raised under our at the Market offering program from October 1, 2025 through November 13, 2025, will be sufficient to fund our operations into the second quarter of 2026. As of November 13, 2025, we had approximately 52.8 million ordinary shares outstanding. Now we will open it up for questions.

Becky - Operator - (00:22:35)

Thank you. If you wish to ask a question, please press STAR followed by one on your telephone keypads. If you feel your question has been answered or for any reason you would like to remove yourself from the queue, please press Star followed by two. When preparing to ask your question, please ensure your device is unmuted locally. I will pause momentarily while we compile the queue. Our first question comes from Ed Oz from West Park Capital. Your line is now open. Please go ahead.

Ed Oz - Equity Analyst - (00:23:22)

Great. Thanks for taking my questions and congrats on the initial launch here. Few questions. First of all, appreciate all the detail here with the launch metrics around the commercialization. Wondering if this is these specific numbers around patients and prescribers and reps and coverage are data points that you intend to report for the first few quarters of the launch for us to track. And related to that, I was wondering if you could discuss the number of actual physician details and also the number of sales regions that you that you currently plan to continue. And I have a follow up. Thanks.

Corey Fishman - Chief Executive Officer - (00:24:20)

Thanks for the questions, Ed. I'll cover this. The question around the metrics. Yes, we do plan to report the, you know, the kind of the prescriptions, the growth, the number of physicians, you know, the general information so people have a sense of how the launch is going. I think at some point if all goes well and we're generating, you know, tons and tons of scripts, we'll do things like most other companies do, which is report the growth quarter over quarter, that kind of thing. So we will be more specific in the first couple quarters till we have some data behind us and then we'll probably branch out to providing the same information but maybe not quite as granular with regard to details and territories. You know, we're not talking about specific number of details. What I will tell you is what I think is important. You know, we started out, our initial thinking was having 20 territories with high value targets. And I think with this change in the organization, as Christine mentioned, as well as the supplemental Resources we will be putting on, we will be in a position to at least effectively cover 20 of those territories, maybe a little more, but ultimately more efficiently. So I think that's probably the range that we'll be in. And you know, again, we'll, we'll continue to report that as we do going forward with regard to how our performance is.

Ed Oz - Equity Analyst - (00:25:59)

Great. Okay. And then around the guidance for net sales next year, you, in your release discussed two particular drivers, payer coverage, which I think you said is currently at 16% of insured lives, and uptake. I'm wondering if you could give a bit more color or details around those two drivers and in particular with uptake, if there's any initial feedback you've gotten from physicians around, you know, the. product. Profile of being oral and keeping the patients at home and how that's driving their interest.

Corey Fishman - Chief Executive Officer - (00:26:53)

Thanks. Sure. So I will cover the second part first, which is the feedback. Feedback from physicians has been very good. I think there's a variety of reasons that physicians are using the product. As Christine mentioned, one of them is certainly to keep those patients that are most at risk out of the hospital. One of them is when you have recurrent infections, you want to make sure you're treating that infection appropriately. Since these folks have been on potentially multiple drugs over a short period of time that haven't worked. And also the folks who have those comorbidities and who are on that higher end of the risk spectrum, I think physicians see this as an excellent option and we will, you know, we'll continue to work with physicians to get that message across. Your other question I think was around, you know, access and coverage. We are, I think, in a good spot. As most of the folks on this call know, you really don't get coverage in the first six months from any plan post launch. That is just something that the PBMs, the pharmacy benefit managers generally do not do. And so we're approaching that six month timeframe in kind of February timeframe for us. And as mentioned, we have submitted bids to all of them. So now it's just a question of being able to get on those plans and get coverage, which will make the process even more efficient. Even though there is a process in place, of course, where you can get those prescriptions filled, we can make it a more efficient process through the addition of orlinba to those formularies. So I think we're really looking at that as an opportunity to have additional efficiency in the system so more and more scripts can be filled while you're continuing to have Strong uptake with these physicians who are prescribing. And again, you know, we've got a lot of physicians that have written multiple scripts already. And I think that's really, you know, an important metric because oftentimes, especially in these places where you haven't had a new product for many, many years, and we know that this has been that place 25, 30 years, docs are pretty ingrained in what they're writing, and so it does take a few visits to get them to write. And the folks who have written, many of them have come back and written again and again and again. So I think we're feeling like we've got a real opportunity here to continue that momentum, and that's really the drivers for us of how we're arriving at the revenue guidance.

Ed Oz - Equity Analyst - (00:29:44)

Thanks so much. I'll jump back in the queue.

Becky - Operator - (00:29:49)

Thank you. Our next question comes from Jason McCarthy from Maxim Group. Your line is now open. Please go ahead.

Jason McCarthy - Equity Analyst - (00:29:57)

Hi, Corey. Nice job of getting things off the ground so far. So, just to follow up on the prior question, did I catch it where you expect formulary? I guess you submitted bids already with PBMs in February of 2026 or sometime in the first quarter?

Corey Fishman - Chief Executive Officer - (00:30:19)

Yeah, we're hoping that's the case. Obviously, we don't have control of that, Jason, but all of our, you know, we're doing everything we can on our end to make that as feasible as possible by having our bids already submitted. So we have now submitted our bids to all the three big PBMs as well as the big Medicare Part D plans. So as we said, we've secured one contract so far on the Medicare Part D side. And so these will hopefully be coming in over the end of this quarter and the first quarter. And that would give us that opportunity to really kind of give an extra boost to the efficiency of the process.

Jason McCarthy - Equity Analyst - (00:30:57)

Is there any effort by Eversun or strategy, rather in terms of advertising or using social media outlets to get the word out on or Linva to try to drive uptake?

Corey Fishman - Chief Executive Officer - (00:31:15)

Yeah, it's definitely something we've thought about. We are, you know, at this stage, we have put the majority of our investment into the field organization and the materials necessary to support that. But it's definitely something that we continue to look at and think about the ways to optimize that social media presence and how we can get that message across, given that we've got that modest infrastructure.

Jason McCarthy - Equity Analyst - (00:31:42)

Okay, do you plan on, and this might have been covered already. Do you plan on, in addition to script data down the road, releasing Any information on the types of patients that are being treated? I don't know if that data is being accumulated, meaning are they high risk or even further, are there specific types of comorbidities and high risk aspects to these patients that you'll gain access to?

Corey Fishman - Chief Executive Officer - (00:32:15)

Yeah, we're not going to have a lot of those specifics because that gets into the doctor patient relationship. I think what we'll end up having is more anecdotal information from those prescribing physicians. And, you know, we certainly will always be cognizant of who's writing, what information can we get from them about the patients and how it's working so we can optimize. And to your point, if we find that a certain comorbidity has been really important for a number of doctors, you know, we, we certainly can get that from them through the sales organization and then figure out a plan to, you know, to optimize that. But it's a little bit trickier just because of all the confidentiality around patient information. And you know, you can't really, you can't really know any of the details on the, on the, you know, the name and anything like that of the patient. It would really have to be more just anecdotal from the docs.

Jason McCarthy - Equity Analyst - (00:33:16)

Got it. And lastly, and this is not really sure the type of answer to expect from this, this is more of a broad thinking because I've been doing this for a long time and I see a lot of one product companies and drug launchers that, you know, they're slow to start, they're choppy. Some people question, you know, you know, what that road's going to look like. But my pushback in this case has been an oral tendon has been sought after for decades. And it's not just for community infections like urinary tract infections. Have you, do you think people are going to want this oral penetration for a variety of things. Have you got an inbound interest in getting access to the drug for any kind of infection?

Corey Fishman - Chief Executive Officer - (00:34:02)

Yeah, we've gotten a lot of inbound interest from people that aren't on our call list that people that we're not covering infectious disease, physicians, et cetera. So I think there's a lot of interest in that. You know, we obviously have a, an indication that we will promote on and that is, you know, that's the only thing we'll, we'll be talking about. But to the extent that there are physicians who call us up and ask for the product, we will absolutely supply it simply because we believe that it's an important piece if a physician's asking for it. And that's why we've gone to McKesson and Syncora, because going through a specialty distributor like ours is out of the kind of their business model for these, these types of physicians who are giving us inbound calls. So, you know, we obviously are going to be very, very mindful as an organization to stay within our approved indication. But we will certainly respond to physicians inquiries because that may very well be for uncomplicated uti. We just, we don't know and you know, physician has the flexibility to write it for whatever it is they choose to write it for.

Jason McCarthy - Equity Analyst - (00:35:09)

Great. Thank you, Corey. Thanks, Jason.

Becky - Operator - (00:35:14)

Thank you. We have another question from Ed Arcy from West Park Capital. Your line is now open. Please go ahead.

Ed Arcy - Equity Analyst - (00:35:24)

Great. Thanks for taking the follow up. I just wanted to ask about this effort to augment the now 10 reps with the virtual effort, especially because you've characterized this as at least replacing the other 10 from the original 20 that you had targeted and perhaps, perhaps a bit more. And so I'm wondering if you could provide some more detail in terms of the capabilities and the ability to engage with physicians through these different virtual platforms. Thanks.

Corey Fishman - Chief Executive Officer - (00:36:14)

Sure. Thanks, Ed. So I want to be really clear, we will probably do a combination of both infield and virtual to get to that at least 20 effective territories, if not more. And so on the virtual side, I think what you have seen, and you've probably seen this in your experience, many companies have used virtual reps who tend to be very efficient because they are using the same target lists, but they're doing this all virtually, so it's all through phone and computer, as opposed to reps who are out there having to drive, having to wait, etc. They can schedule meetings. They can be quite, quite a bit more efficient on the interactions with physicians simply because they are, you know, they're sitting at a desk, not trying to drive around and find people and, or get in through the office. So those people tend to be based on the experience that Eversana has had, as well as a lot of other companies that we've all spoken to have had a very good reputation of being efficient in terms of producing performance. So we believe that those, those virtual reps can be a very important part of our organization in addition to the infield reps. I don't want to minimize one or the other because they're both incredibly important, but we do think the combination of the two is really, really going to give us the opportunity to reach a lot of targets in an effective way and hopefully drive that performance to the place where we, you know, we are, we're talking about.

Ed Arcy - Equity Analyst - (00:37:57)

Okay. At this point, are you considering other marketing channels like medical journals or engagement via social media or other channels like that?

Corey Fishman - Chief Executive Officer - (00:38:14)

Yeah, I think, you know, what we've talked a lot about with our partners of Ursana is things like social media tend to be more effective, effective nowadays than the traditional kind of journal ads and things like that. But we will continue to look at them. We'll continue to look at historical return on investment for those types of investments over various companies like ours that have used them, and we'll try to optimize those as best we can. Again, we're trying to be as mindful as we can about the capital we have and putting it where we believe we're going to get the biggest bang for the buck. And right now that tends to be the field organization. Hopefully we'll have a little more flexibility if we're successful in raising more capital to put some of those other things into play and, you know, altogether, then it makes everything more efficient. It's just a question of having that flexibility.

Ed Arcy - Equity Analyst - (00:39:09)

Sounds good. Thanks again and congrats and best of. Luck as you can. Thanks for the questions.

Becky - Operator - (00:39:20)

Thank you. This concludes our Q and A session, so I'll hand back over to Corey Fishman for closing remarks.

Corey Fishman - Chief Executive Officer - (00:39:27)

Thank you, Becky. In closing, we believe we've made some very solid progress in the first 10 weeks of Orlinva commercialization. Physicians see a place in the market for Orlimba and many physicians have begun prescribing for multiple patients. We will continue to work tirelessly toward growing the Orlinva patient base and driving incremental revenues. We really appreciate your support as we continue the Orlinva commercialization and are looking forward to keeping you updated as our key milestones are met. Thanks again for joining us today and have a good day.

Becky - Operator - (00:40:07)

This concludes today's call. Thank you for joining us. You may now disconnect your lines.
