Thank you, Marianne, and thank you all for joining our call today. Today, Puma reported total revenue for the second quarter of 2026 of $56.5 million. Total revenue includes product revenue net, which consists entirely of Neuralink sales, as well as royalties from our sublicensees. Product revenue net was $53.6 million in the second quarter of 2026, an increase from $42 million reported in Q1 of 2026 and $49.2 million reported in Q2 of 2025. As a reminder to investors, Puma's reported Neuralink sales includes both U.S. net sales of Neuralinks and product supply revenues of Neuralinks to Puma's ex-U.S. partners. Product revenue for the second quarter of 2026 included approximately $1.3 million of inventory drawdown at our specialty pharmacies and specialty distributors. Royalty revenue was $2.9 million in the second quarter of 2026 compared to $2.8 million in Q1 2026 and $3.2 million in Q2 of 2025. We reported 2,929 bottles of Neuralink sold in the second quarter of 2026 compared to 2,328 bottles sold in Q1 of 2026. In Q2 2026, we estimate that inventory decreased by 57 bottles. In Q2-2026, new prescriptions were down approximately 6% compared to Q1-2026. The total prescriptions were up approximately 7% compared to Q1-2026. Roger will provide further details in his comments and slides. I will now provide updates from PUMA's ongoing phase 2 trials of allacertib in small cell lung cancer and HER2 negative ER positive breast cancer, also referred to as ALISCA Lung 1 and ALISCA Breast 1. Heather Blaber and Roger Storms will add additional color on Nealink's commercial activities. Maximo Nuguez will follow with highlights of the key components of our financial statements for the second quarter of 2026. As investors are aware, Puma has two ongoing phase 2 trials of our investigational drug Allisertib, Aliska Breast 1, which is a phase 2 trial of Allisertib in combination with endocrine therapy in patients with HER2-negative, hormone receptor-positive, recurrent, or metastatic breast cancer, and Aliska Lung 1, a phase 2 study looking at the efficacy of Allisertib model therapy in patients with small cell lung cancer. As a reminder, the Aliska Breast 1 trial investigates Allisertib in combination with endocrine treatment consisting of either anastrozole, eczemestane, letrozole, fulvestrant, or tamoxifen in patients with HER2-negative, hormone receptor-positive, recurrent or metastatic breast cancer. Patients must be chemotherapy-naive in the recurrent or metastatic setting, have had previous treatment with a CDK4-6 inhibitor, and have received at least two prior lines of endocrine therapy in the recurrent or metastatic setting to be eligible for the trial. Patients were initially being dosed with allacertib given at either 30-year milligrams, 40 milligrams, or 50 milligrams twice-daily BID on days 1 to 3, 8 to 10, and 15 to 17 on a 28-day cycle in combination with endocrine therapy of the investigator's choice. Patients must not have been previously treated with the endocrine treatment in the metastatic setting. That will be given in combination with allacertib in the trial. Interim data from this trial was presented on the company's first quarter conference call. As discussed during that presentation, the company believes that the data obtained to date from ALISCA Breast 1 is providing a preliminary indication of potentially better activity in patients with biomarkers where the aurora kinase pathway plays a role. Based on the feedback that we have received from breast cancer key opinion leaders on this interim data, the trial has been amended such that now we are only continuing enrollment in the 40-milligram and 50-milligram dose groups. That amendment to the protocol has been submitted to the FDA and the EU authorities and is being submitted to the IRBs as well. We are hoping to begin enrollment under that amended protocol in Q3. We will also be updating interim data from the ALISCA Breast 1 trial, including longer-term patient follow-up in the fourth quarter of this year. With respect to the ELISCA Lung 1 study, as investors are aware, Puma has an ongoing Phase 2 trial of our investigational drug, Allocertib, to investigate the efficacy of Allocertib monotherapy in patients with small cell lung cancer. Interim data from this trial was presented on the company's first quarter earnings call. As discussed during the presentation, the company believes that the data obtained to date for Mollisca Lung 1 is providing a preliminary indication of potentially better activity in patients with the biomarkers where the aurora kinase pathway is playing a role. As was also discussed on that call, the company previously amended the trial to increase the dose from 50 milligrams BID to 60 milligrams BID. Dosing of the trial was further increased to 70 milligrams BID, and the company is currently enrolling patients at the 70 milligram BID level. There are currently 92 patients in the trial, with 36 of the patients enrolled at the 60-milligram BID dose and 4 patients enrolled at the 70-milligram dose. As was often mentioned on the recent earnings call, Puma also plans to initiate a second trial of allocertib in small cell lung cancer, Aliska Lung 2, where the drug will be given in combination with paclitaxel similar to the Phase II randomized trial that was previously published in the Journal of Thoracic Oncology. The company anticipates that enrollment in the ELISCA Lung 2 trial will start in Q3, and the company will provide investors with further information on this trial in the future. The company anticipates that it will have additional interim data from ELISCA Lung 1 and the initial data from ELISCA Lung 2 in 2027. As mentioned on prior earnings calls and in response to investor questions, PUMA continues to evaluate several commercial-stage and development-stage drugs to potentially in-license or acquire that would allow the company to diversify itself and leverage Puma's existing R&D, regulatory, and commercial infrastructure. The company will keep investors updated on this as it progresses. I will now turn the call over to Heather Blaber for an update on our marketing initiatives. Roger Storms will follow with a review of our commercial performance during the quarter.

Thanks, Alan. I appreciate the opportunity to share some additional insights into our marketing strategy. The marketing team is focused on continued awareness of both clinical data for Neuralink, as well as reinforcing the continued unmet need in HER2-positive early-stage breast cancer after adjuvant therapy. We continue to invest in market research to help us understand and validate the most effective ways to communicate our data with healthcare professionals through both personal and non-personal promotion. Our strategy is focused on increasing awareness of our dual-indication in HER2-positive breast cancer. We believe Neuralynx plays an important role in the early stage by reducing the risk of recurrence and in the metastatic setting by helping protect against progression. Not only do physicians who have experience with Neuralynx continue to identify appropriate patients that could benefit from additional therapy post-adjuvant treatment, but we continue to adopt new prescribers year over year who recognize the unmet need and HER2-positive early-stage breast cancer and how Neuralynx may help their patients reduce their risk of recurrence. In summary, we are excited and committed to engage with more oncologists and support their patients diagnosed with HER2-positive breast cancer in both the early and metastatic settings. I will now turn the call over to Roger Storms to provide an overview on the commercial performance for the second quarter.

Thank you, Heather, and thanks to everyone for joining our second quarter earnings call. Before I move into the commercial review, just a reminder that I'll be making forward-looking statements. The sales team remains focused on increasing the use of Neuralink with a main focus on patients at higher risk of recurrence. They are also dedicated to enhancing clinical education and engagement through non-personal promotional efforts as well as utilizing patient resources to support persistence and compliance during Neuralink's therapy. Let me now transition to some of the commercial slides where I'll provide some additional specifics around performance. Slide three is an illustration of our distribution model, which is broken out into the specialty pharmacy channel and the specialty distributor or in-office dispensing channel. Regarding the overall distribution of our business, in Q2 2026, about 61% of our business was purchased through the SP channel, and the remaining 39% was purchased through the SD channel. We continue to see stronger growth in the SD channel driven by two main factors, increased sales in the group purchasing organizations, or GPO segment, and increasing 340B purchasing. Turning to slide four, Neuralink's net product revenue in Q2 2026 was $53.6 million, an increase from the $42 million we reported in Q1 2026 and the $49.2 million we reported in Q2 of 2025. As a reminder to investors, Puma's reported narrow-link sales include both U.S. net sales of narrow-links and product supply revenues of narrow-links to Puma's ex-U.S. partners. Please note that in Q2-2026, we reported minimal product supply revenue to our international partners versus about $100,000 in Q1 of 2026. I will provide some more details around inventory changes, and Maximo will provide some additional specifics around gross-to-net expenses during his update. In Q2-2026, we estimate that inventory decreased by about $1 million. As a comparator, we estimate that inventory decreased by about $7.9 million in Q1 of 2026. Slide 5 shows Q2-2026 X-Factory bottle sales and also provides both a year-over-year and a quarter-over-quarter comparison. As a reminder, X-Factory bottles include sales to our SP and SD channels. In Q2 2026, Narrowlink's X-Factory bottle sales were 2,929, which represents an approximate 26% increase quarter-over-quarter and 12% increase year-over-year. Let me specifically call out the inventory changes from a bottle perspective. In Q2 2026, we estimate that inventory decreased by 57 bottles. As a comparator, we estimate that inventory decreased by 439 bottles in Q1 of 2026 and decreased by 85 bottles in Q2 of 2025. Slide 6 highlights our commercial demand for the quarter. In Q2, 2026, U.S. demand was 2,986 bottles, which represents an approximate 8% increase quarter-over-quarter and 11% increase year-over-year. As mentioned earlier, we have seen stronger growth in the SD channel, where we saw demand grow by about 12% quarter-over-quarter and 32% year-over-year. The year-over-year and quarter-over-quarter increases are a direct result of continued emphasis put on executional excellence and increased field accountability. Our Q2 2026 call activity increased 18% year-over-year and 2% quarter-over-quarter, and total prescriptions, or TRX, increased by 7% quarter-over-quarter and 3% year-over-year. Enrollments in the quarter grew 1% quarter-over-quarter and 12% year-over-year. Commercial new patient starts in the quarter declined 6% quarter-over-quarter and grew 8% year-over-year. Continued messaging and adoption of dose escalation remains an important commercial priority, and 73% of patients started NeerLinks at a reduced dose. We believe dose escalation coupled with patient education resources will give patients better support throughout their Neuralink's therapy and ultimately help them reduce the risk of recurrence. Slide 7 highlights the strategic collaborations we formed across the globe. Most recently, in Q1, 2026, Neuralink's was launched in Thailand, also in the extended adjuvant setting. We really appreciate the excellent work being done by our partners around the world and look forward to supporting their continued success moving forward. I'll close by sharing my sincere appreciation for the entire Puma team and their steadfast commitment to supporting patients and families affected by breast cancer. This disease is truly devastating, and while meaningful progress has been made, we know there is still important work ahead and even more we can accomplish together. I will now turn the call over to Maximo for a review of our financial results.

Thanks, Roger. I will begin with a brief summary of our financial results for the second quarter of 2026. Please note that I will make comparisons to Q1 2026, which we believe is a better indication of our progress as a commercial company than year-over-year comparisons. For more information, I recommend that you refer to our second quarter 2026 10Q, which will be filed today and includes our consolidated financial statements. For the second quarter of 2026, we reported net income based on GAAP of $8.2 million, or $0.16 per diluted share. This compares to a net loss in Q1-2026 of $3.8 million, or $0.07 per share. On a non-GAAP basis, which is adjusted to remove the impact of stock-based compensation expense, we reported net income of $10.1 million, or $0.20 per basic share, and $0.19 per diluted share for the second quarter of 2026. Gross revenue from Netlink sales was $74.3 million in Q2-2026, and $57.5 million in Q1-2026. As Alan mentioned it, net product revenue from Nerlinx sales was $53.6 million, an increase from the $42 million reported in Q1-2026 and the $49.2 million reported in Q2-2025. As a reminder to investors, Puma reported Nerlinx sales include both U.S. net sales of Netlinks and product supply revenue of Netlinks to Puma ex-U.S. partners. Please note that in Q2, 2026, we reported product supply revenue to our international partners of around 23,000. Therefore, U.S. net sales of Netlinks in Q2, 2026 were 53.6 million versus 41.9 million in Q1-2026. The increase in net product revenue in Q2-2026 versus Q1-2026 was driven by higher demand, inventory decrease in Q2 of about $1.3 million versus inventory decrease of $7.9 million in Q1-2026, upset by a higher gross to net in Q2. Royalty revenue totaled $2.9 million in the second quarter of 2026 compared to $2.9 million in Q1 2026. Our gross to net adjustment in Q2 2026 was about 27.9% and 27% in Q1 2026. The high gross to net adjustment was driven by higher Medicaid share. Coftal sales for Q2 2026 was $12.5 million and includes $2.4 million for the amortization of intangible assets related to our Neratinib license. Cost of sales from Q1-2026 was $10.4 million. Going forward, we will continue to recognize amortization of milestones to the licensor, about $2.4 million per quarter as cost of sales. For fiscal year 2026, Puma anticipates that net Nerlinx product revenue will be in the range of $205 to $209 million, higher than our prior guidance of $202 to $206 million. We also anticipate that our gross to net adjustment for the full year 2026 will be between 26.5% and 27.5%. In addition, for fiscal year 2026, we anticipate receiving royalties from our partners around the world in the range of $19 to $22 million, slightly lower than our prior guidance of $20 to $23 million. Under our sub-license agreement covering China, the royalty rate payable to us is subject to reduction when the market share of generic versions of Neurlinks in China reaches a specific threshold. We are unable to predict with certainty when this threshold will be reached. However, we believe it is possible that the threshold could be reached, triggering the royalty rate reduction in late 2026 or in 2027. We don't expect any licensed revenue in 2026. We also expect that net income for the full year will be in the range of $17 to $20 million, also higher than our prior guidance of $16 to $19 million. The current guidance does not include any potential release of any additional tax asset valuation allowance in our net income estimate. The company is reviewing its deferred tax assets as part of its ongoing tax valuation analysis and has not yet determined whether any adjustment will be required or, if so, the potential timing or size of such an adjustment. We will continue to keep investors updated on this as it progresses. At this time, we do not believe that the tariffs imposed or proposed to be imposed by the United States, particularly with other countries, will have a material impact on our product cost or results of operation. However, shifting trade policies in the United States and other countries have been rapidly evolving and are difficult to predict. As a point of reference, our manufacturing product cost accounts for a mid- to high single-digit percentage of our total cost of goods We anticipate that for Q3 2026 Narlink's product revenue net will be in the range of $54 to $56 million. We expect Q3 royalty revenues will be in the range of $2 to $3 million and no license revenue. We further estimate that the gross to net adjustment in Q3 2026 will be approximately 26 to 27%. PUMA anticipates a Q3 net income between $2 million and $2.5 million. SG&A expenses were $17.5 million in the second quarter of 2026 compared to $18.4 million in the first quarter of 2026. SG&A expenses include non-cash charges for stock-based compensation of $1.2 million for Q2 2026 and $1.1 million for Q1 2026. Research and development expenses were $18.9 million in the second quarter of 2026 and $19.8 million in Q1, 2026. R&D expenses included non-cash charges for stock-based compensation of $0.8 million in Q2, 2026, and $0.8 million in Q1, 2026. On the expense side, Puma anticipates higher total operating expenses in 2026 compared to 2025. More specifically, we anticipate SG&A expenses to increase by 1% to 2% and R&D expenses to increase by 34% to 37% year-over-year. The higher increase in R&D is driven by the progress of our clinical trials. In the second quarter of 2026, PUMA reported cash burn of approximately $9.7 million. This compares to cash earned of approximately $4 million in Q1. Please note that during Q2-2026, we made our final quarterly principal loan payment of $11.1 million related to our obligation with Ethereum. As a result, Puma now is debt-free. At June 30, 2026, we had approximately $93.9 million in cash, cash equivalents, and marketable securities versus $97.5 million at year-end 2025. Our accounts receivable balance was 34.1 million. Our account receivable terms range between 10 and 68 days, while our day sales outstanding are above 44 days. We estimate that as of June 30, 2026, our distribution network maintained approximately three weeks of inventory. Overall, we continue to deploy our financial resources to focus on the commercialization of Neuralink, the development of all assertive, and controlling our expenses.

Thanks, Maximo. On past earnings calls, we have stressed that Puma Senior Management, in cooperation with the Board of Directors, continues to remain focused on Neuralink sales trends and recognizes its fiscal responsibility to shareholders to continue to maintain a positive net income. We believe that this focus has contributed to our commercial execution thus far in 2026. According to our current projections, 2026 will mark the second year-over-year demand increase for Neuralink's in the United States and the first time in the history of the launch of Neuralink's in the United States that we have seen two positive consecutive year-over-year increases in demand. We are pleased to report this demand-driven increase in Neuralink sales in the second quarter of 2026, and we believe that the positive net income that the company is guiding to for full year 2026 has resulted from both this increased demand as well as the continued financial discipline across the company over the last few years. The company remains committed to continuing to achieve this positive net income and will continue to reduce expenses if needed to achieve this. We look forward to updating investors on this in the future. There continues to remain a significant unmet need for patients battling breast cancer, lung cancer, and other solid tumors. We at Puma are committed and passionate about finding more effective ways at helping these patients during their journey, and we will continue to strive to achieve that goal. This concludes today's presentation. We will now turn the floor back to the operator for Q&A. Operator?

Thank you. We will now begin the question and answer session. If you wish to ask a question, please press star 1 on your telephone keypad. A confirmation tone will indicate your line is in the question queue. If you wish to withdraw your request, please press star 2. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment, please, while we poll for your questions. Our first questions come from the line of Mark Graham with TD Cowan. Please proceed with your questions.

Thanks, and congrats on the strong quarter and recent commercial performance. Maybe looking a little further beyond the formal guidance, you have a couple trials ongoing and another one going to start up. Can you speak to, Alan, what the kind of R&D spend trajectory looks like maybe beyond just kind of Q3 and more into – as we look into 27 as some of those trials are a little more fully up and running?

So in terms of the R&D in 27, 28, 29, you know, we've gotten this question from investors before, which is, you know, let's say you want to do the phase three trials of both, you know, allocerative in ER-positive breast cancer and in small cell lung cancer. Can you do that? And the answer to that is, you know, according to our current projections, yes. We probably have to stagger them. So, like, you know, start one before the other type of thing. But it is completely achievable, and that's what we're looking to do. You know, we think that with the, you know, thankfully now we're a debt-free company. So we've, you know, we're cash flow positive. Obviously, investing that in Alicertib is a good thing with the shareholders. It's a very, very interesting drug. We're very pleased with the data. And assuming the data continues to hold up, we're very eager to start in Phase 3 trials. And I think that we have the ability to do that, hopefully, knock on wood, next year. And I think that's where we're heading. So I think there's no reason we can't run both of them. Like I said, we are committed to maintaining, you know, positive net income. So if we have to stagger the trials, then we can stagger them.

Okay, that's helpful. And then also in your prepared marks, I mean, you mentioned, you know, continuing to evaluate BD opportunities. Can you speak a little bit more as to kind of what would be of interest? I mean, should we look at Al-Acertib as very much the model in terms of kind of size of the stage? Or, you know, would you be willing to take on maybe either a little bit more of an upfront or your maybe a little bit earlier stage projects?

Yeah, so from a BD perspective, we look at commercial assets and we look at, you know, development stage ones. On the commercial side, you know, I think that we've shown a, you know, strong ability to, you know, Obviously, cut costs, generate cash from a commercial asset, and if there's ones out there where we feel like we could fit it into the existing organization and continue to do that for shareholders, add on additional sales, build additional cash, I think that would be something very wise to do for the shareholders. On the development stage side, you know, obviously there's a lot of drugs being developed right now in the oncology space. You know, if there's something where we feel that it's a unique asset and something where we, you know, believe that, you know, we can contribute to shareholder value by bringing it in and developing it clinically, you know, we're happy to look at that. We're not technology agnostic, if you will, like we just only look at small molecules or something like that. We're happy to look at, you know, anything, any other technologies. And I guess the same thing would be true on the commercial side as well. You know, is it just something in breast or lung cancer? Again, you know, happy to look at things that are outside of that if we feel that we can, you know, number one, most importantly, help cancer patients. And number two, by helping cancer patients benefit the shareholders.

Okay. That's helpful.

Thank you. This concludes our question and answer session. I will now turn the conference back to Marianne for closing remarks.

Thank you all for joining us today. As a reminder, this call may be accessed via replay of the webcast at PumaBioTechnology.com beginning later today. Have a good evening.

Ladies and gentlemen, thank you for participating in today's conference call. This concludes our program. Everyone have a great day. You may now disconnect.
