Now I’ll turn the call over to Dr. Rothblatt for an overview of our third quarter 2023 financial results and the business activities of United Therapeutics. Martine?

Thank you, Dewey. First off, I’d like to congratulate our team as we had an amazing third quarter for the second quarter in a row. I’m thrilled to report our highest quarterly revenue ever along with double-digit revenue growth as compared to the third quarter of 2022. On top of that, our operational efficiency in the third quarter resulted in one of our highest quarterly net incomes and earnings per share ever. At United Therapeutics, we’re uniquely positioned for three waves of growth with a profile that’s unique in biotechs. Our first wave of growth will come through our existing commercial business led by Tyvaso and pulmonary hypertension associated with interstitial lung disease or PH-ILD. We continue to post solid growth in our current business with record quarterly revenue and patients on therapy for treprostinil products as a whole. Our growth in PH-ILD and continue leadership in pulmonary arterial hypertension or PAH has led to nebulized Tyvaso and Tyvaso DPI products combining to become the most prescribed prostacyclin therapy in the U.S. Michael will go into detail on our commercial business later in this call. We believe this growth will continue in the near term and we expect at least a $4 billion annual revenue run rate by mid decades doubling our revenue from 2022 and implying a double-digit compound annual growth rate. Our second wave of growth will come from our near-term pipeline led by the TETON program in pulmonary fibrosis and ralinepag in PAH. These two products, if approved, could lead our revenue to double again to $8 billion by the end of the decade. I will provide updates on the TETON and ralinepag program shortly. Of course, both of our first and second waves of growth are subject to clinical trial outcomes, regulatory approvals, new competitive entrants…

Thanks, Martine, and good morning, everyone. As Martine noted, today, we reported our highest revenue quarter ever at $609 million, up 18% from the third quarter of 2022. We saw meaningful growth for each of the Tyvaso franchise, Remodulin, Orenitram and Unituxin. With respect to Orenitram, we saw revenue of $92 million during the quarter, which was up 5% from the prior year. This growth reflects increases to both patient growth and average dose. In the third quarter, following the publication of two peer-reviewed manuscripts, we are also able to commence education efforts by our field-based teams on the EXPEDITE protocol, which is based on our rapid Remodulin titration and transition to Orenitram study, allowing patients to get to higher doses of Orenitram quicker and with less side effects than starting Orenitram de novo. Remodulin revenue of $131 million was up 15% from last year, reflecting both U.S. patient growth from the third quarter of 2022 as well as an increase in international sales from the same period last year. Patients who use our Remunity Pump now make up more than 50% of subcutaneous Remodulin patients in the U.S. compared to under 10% at the same period just last year. Remodulin continues to be the Number 1 prescribed parenteral therapy for PAH in the U.S. Moving to Unituxin; we saw revenue of $51 million, which was up 11% from the prior year quarter. This growth was driven by an increase in U.S. sales and includes a modest inventory build at our U.S. distributor. Finally, Tyvaso; We saw revenue of $326 million for Tyvaso DPI and nebulized Tyvaso combined, which was up 26% from the prior year quarter and was the highest Tyvaso revenue quarter ever. This growth was principally driven by new patients on therapy. This performance reflects the rapid…

Thanks Mike. I hope everyone can tell that United Therapeutics is a truly compelling investment with a strong cash-generating commercial business supporting novel R&D efforts in rare lung disease, coupled with the revolutionary potential for our organ manufacturing programs. Operator, let's start the Q&A session.

Thank you. [Operator Instructions] Today's first question comes from Terence Flynn with Morgan Stanley. Please go ahead.

Great. Congrats on all the progress. Thanks for taking the question. I was just wondering, maybe it's a question for Mike, if you can offer any perspective on Tyvaso net adds, in the quarter if that's been pretty consistent at that 500 patient level. And then are you able to tell us where inventory levels shook out for the quarter? Like was – did the quarter include a significant build? Or was this all demand driven? Thank you, on Tyvaso specifically.

Thank you, Terence. Mike?

Sure. Yes. So the net adds continue to kind of clip along at kind of that roughly 500, sometimes a little higher, sometimes a little lower, but kind of in that range per quarter. So we're really happy with that – that continued progress. And as I said in the third quarter, we saw a record number of prescriptions and starts. And so just continue to kind of pull that through and keep those patients on therapy. So we're pleased with the progress on that front. From an inventory standpoint and the revenue numbers, not – I think what you can infer from the revenue numbers is that the revenue number revenue numbers reflect underlying patient demand. So there wasn't really a significant inventory build in the quarter. And as I said, with the enhancements that we've seen at MannKind since June, we think we're – plus what's coming next year, we're really well positioned from an inventory standpoint going forward.

Thank you very much, Mike. Operator, next question please?

Absolutely. Our next question comes from Hartaj Singh with Oppenheimer. Please go ahead.

Great. Thank you for the question, and really nice quarter. Just maybe a little bit of a different tack, which is that you had really nice revenues across the board, especially Tyvaso, but you're really holding your OpEx pretty firm and staying to that algorithm that James has talked about previously. Your operating margin just seems to keep on getting better. Can you just talk a little bit about that progression? And do you expect that to keep getting better as your PAH franchise becomes even more profitable? Thank you for the question.

Thank you very much, Hartaj. James Edgemond is our Chief Financial Officer. So James, could you please answer that question?

Yes. Thanks, Martine. Good morning, Hartaj and thank you for the question. As a reminder and you alluded to this in your question we still and will apply that budget algorithm where we will spend no more on cash, operating budget in 2023, for example, that exceeds 50% of prior year revenue. So our budget algorithm this year and continuing forward, we expect to apply. With respect to your question on the operating margin, specifically, in an environment of continued revenue growth, which we've demonstrated, you will have improving operating margins over time. But remember, that can bounce around quarter-to-quarter because we typically look at our budgets and our budget spend on an annual basis. And those expenses could be impacted by clinical trial enrollment and the timing around that, for example. But from a fiduciary and kind of fiduciary responsibility perspective, we do want to continue and we will expect to continue to apply the budget algorithm, be good financial stewards of the expenses. And as you heard Michael talk about in a very successful quarter and growing revenue when you think about some of the investments that Michael has made as well. So thank you very much, and Martine, back to you.

Thank you, James. Thank you, Hartaj. Operator, next question please.

Our next question comes from Joseph Thome with TD Cowen. Please go ahead.

Hi there. Good morning and thank you for taking my questions. Obviously, a lot of progress on the organ side of the business this quarter. When we think about the xenokidney, the mirokidney and the IVIVA kidney implant. Should we think of these largely as sort of three shots on goal in kidney transplant? Or are there discrete populations that could benefit from each of these products? How do you view that? Thanks.

Thank you, Joe. I think the answer is all of the above, both of the above to be specific. Definitely, positively, there are multiple shots on goal, but there is a large diversity of different types of manifestation of end-stage organ disease generally and specifically within kidney disease. So I could very much see products from one of the other groups, whether it's a xenokidney or autologous IVIVA kidney or a allogeneically cellularized with primary cells mirokidney going to different end-stage kidney disease patient populations. As you know, Joe, there are more than 0.5 million people just in the United States on dialysis. So the level of demand is really off the charts, and we're confident that each of these kidney technologies and our other organ technologies we'll find very, very receptive physicians and patient populations for their use. Thanks for the question, Joe. Operator, next question please.

Absolutely. Our next question comes from Eun Yang with Jefferies. Please go ahead.

Thank you. So you recently started another Phase 3 TETON study for progressive pulmonary fibrosis. I'm just wondering why you are not using the DPI formulation in the trial. And once it's approved, do you think you may not need a bridging study to DPI from the nebulizer similar to PH-ILD? Thank you.

Thank you, Eun. Very good question; I'd like to ask the clinical trial executive responsible for that study, Dr. Leigh Peterson, if she could please answer your question.

Yes, sure. Thanks for the question. Regarding why we're not using the DPI, we want to use the nebulizer to remove as many variables as possible between the studies. So between the INCREASE study and TETON 1, TETON 2 and TETON PPF, so we're sticking with the same delivery device for those. And yes, we'll definitely seek approval for the DPI once we see the results of these studies with a nebulizer. It's – we're still having ongoing conversations with FDA to determine what will be required for that approval.

Thank you very much, Dr. Peterson. Thank you very much, Eun, for your question. Operator, next question please.

Our next question today comes from Jessica Fye with JPMorgan. Please go ahead.

Hey guys. Good morning. Thanks for taking my question. Question on Tyvaso. So recognizing that titration dynamic you mentioned, which could suggest that the mix of new starts between DPI and nebulized Tyvaso understates the longer-term proportion who might end up on DPI. Can you talk about what you’re seeing as a mix among new starts as well as your latest expectations for the longer-term mix of Tyvaso DPI and nebulized Tyvaso within the franchise? Thanks.

Thank you very much Jess. Mike, would you be able to give some color on that question please?

Sure. Happy to. So Jess with respect to referral, sorry, with respect to the mix between the nebulizer and the DPI, I think we’ve said for the last couple quarters that it’s been kind of in the neighborhood of two thirds DPI, one third nebulizer that continues to hold true. That’s what we saw in the third quarter and actually was a couple points higher on the nebulizer in the third quarter than the prior quarters. But it’s generally kind of in that, kind of two thirds 65% to 70% DPI, 30% to 35% nebulizer. I kind of expect that it’s going to stay there. It could tip up a little bit towards DPI after the first of the year when some of the new Medicare Part D redesign elements. It's kicking under the IRA and patient out of pocket goes down. So to the extent that reimbursement challenges are a reason for using the nebulizer that might tilt things a little bit more towards DPI. But as I said in my opening comments, I continue to think that there’s going to be a role for nebulizer. I think what we have learned over the 25 years to 30 years that we’ve been in this space is that patients are very different and some react better to one delivery device over another and vice versa. And so, we’re just really happy that we have multiple options to offer patients. And at the end of the day we’re really, we’re kind of agnostic as to which device it is because either way they’re running United – the patients are benefiting from a United Therapeutics product.

Thank you so much, Mike. And Jess, thank you for the question. We’re at the end of the call. But we have time for just one last question. Operator, last question, please.

Thank you. Our final question today comes from Ash Verma with UBS. Please go ahead.

Great. Congrats on the quarter. Thanks for taking our question. So I have two. On the manufacturing expansion for Tyvaso at your partner MannKind for the DPI that was up 2.5x in June. Is that now allowing you to fulfill the minimum contractual levels at your distributors, or would that level of supply only be fully enabled by the second production line that MannKind is building? That’s first. And I mean, there’s a lot of pipeline for Tyvaso, very excited about PPF, IPF, but just curious the timelines for the enrolling these studies are a little bit protracted. Is that primarily because of the heterogeneity of the disease or just curious if there is any other factor playing in that? Thanks.

Okay. Ash, thanks for that question or that compound question. So let’s have the first part of your question relating to manufacturing be answered by our Executive Vice President for Technical Operations, Pat Poisson. And when he’s done answering the first part of your question, the second part of your question relating to the timelines for enrollment in the pulmonary fibrosis studies that one will be answered by Dr. Leigh Peterson. Pat, can you go first?

Sure. Thanks, Martine. And thanks for the question. So the process improvements we implemented earlier this year will fulfill demand both near and midterm for Tyvaso DPI, longer term, as we see growth in ILD will certainly need the new equipment that is coming online in the first half of 2024. So as of right now we’re able to fulfill demand and maintain inventory levels at the SPs [ph] and we’ll be able to do so until the new equipment comes online. And then we’ll be well prepared for the future.

Thank you, Pat. Dr. Peterson?

Yes. So thanks for the question on our TETON program. We actually haven’t increased our timeline. I mean, we’re still on target to finish enrollment of the TETON studies at the end of 2024. But you’re right, we have increased the sample size and we’re now targeting the enrollment of the 576 patients in each study. And the reason for that is you’re exactly right. You mentioned the variability of the disease and we do routine blinded data looks and that is what we saw there was some basically standard deviations of the FEC and the completers prompted us to just out of caution to increase the sample size to increase the chance of success. But again just because of the pace of enrollment into these studies, which is fairly rapid. We haven’t increased our overall timeline to enroll those additional patients.

Thank you so much, Dr. Peterson. Ash, thank you so much for the question. In conclusion, as mentioned earlier, we’re really happy to be in such a great position here at United Therapeutics. We have a solid commercial business posting record results with continued strong growth ahead. We have a pipeline of novel therapies that could again double our revenue by the end of the decade. And we have a long-term plan to address one of the largest critical unmet medical needs. All of the above, while helping our patients, employees, and shareholders succeed. Operator, you may now terminate the call.
