Thank you so much, Peter, and good afternoon, everyone. We're continuing to advance Sera's commercial progress and building momentum in our business. Today, I'll review how we plan to grow market awareness through data generation. I'll then review our commercial strategies and tactics and how we're engaging with professional societies and opinion leaders to support our role as the pregnancy company. In terms of data generation, we continue working towards the publication of our full PRIME study results in a peer-reviewed publication. This first PRIME publication will include the strong primary outcomes we shared earlier this year as well as new and compelling data points from the study, demonstrating the efficacy of the PreTRM Test. We remain actively engaged with the reviewers and remain optimistic that publication will occur before year-end. We know publication is important to our stakeholders, and we will keep you apprised and certainly announce publication as soon as it arrives. I will note that from a commercial perspective, payers have shown high willingness to engage with us on the abstract and podium presentation by our principal investigator at the Society for Maternal Fetal Medicine, or SMFM meeting last January, allowing us to make progress on our reimbursement strategy. To add to the strong and compelling data from this initial PRIME publication, we plan to swiftly follow up with additional publications of data on health economic benefits, subpopulation analysis, for example, first versus second, third, fourth time moms and Medicaid, expected cost savings of Sera's PreTRM Test. Many state Medicaid programs cover the first 12 months of health care for newborns, and we believe the cost-saving benefits of PreTRM Test will be very compelling as state governments seek to reduce overall Medicaid costs. As a reminder, our PRIME study results reported in January demonstrated that we can…

Thanks, Zhenya, and good afternoon, everyone. Let me review our financial results for the second quarter. Net revenue for the second quarter of 2025 was $17,000 compared to $24,000 for the second quarter of 2024. Total operating expenses were $9.3 million and flat with the same period a year ago. Research and development expenses of $3.3 million were down from $4.4 million or approximately 24% relative to the prior year period due to lower clinical study costs following the completion of the PRIME study and a shift toward commercialization. Selling, general and administrative expenses for the second quarter were $6.0 million, up from $4.9 million for the second quarter of 2024 as we continue to carefully invest in targeted commercial activities, build market awareness and recently add strategic headcount to drive future revenue. Net loss for the quarter was $8.0 million, down from $8.3 million for the same period a year ago due to our continued focus on managing capital resources ahead of expected revenue expansion. As of June 30, 2025, the company had cash, cash equivalents and available-for-sale securities of approximately $108.5 million, which we expect will fund the company across significant adoption and commercial milestones through 2028. We will continue to be good stewards of our cash position as we build towards revenue inflection, and we'll continue to invest where we see opportunities with commercial merit that could expand preterm awareness and test volumes. Operator, we can now please open the call for questions.

[Operator Instructions] Your first question is from Andrew Brackmann from William Blair.

This is Maggie Boeye on for Andrew today. Maybe first, just on your commercial efforts, given that you did add Lee in May. Can you talk about how we should be thinking about the different milestones as you continue to build out your commercial sales force? Is there just -- has there been any shifts or changes since he has joined and potentially added new perspectives?

Maggie, thank you so much for your question. Good to hear you. First of all, of course, Lee brings in decades of experience of traditional commercialization playbook in diagnostics. And one of the first things in his remit was to take a look at our commercial strategy. One of the first elements that he added is the emphasis on just how much the test itself can help augment the care protocols for the pregnancy in order to empower the physicians to select the right treatments and intervention methods. So we are very excited to emphasize that in our commercial messages and in the data that we generate and empower our sales team with. Second key priority for him was, of course, expanding our commercial team. And he brought his perspective on who are the types of sales leaders who can really propel us forward in commercial momentum with the strength of the data that we are receiving right now from PRIME study. So we have stepped up the level of seniority and experience in the reps that we brought in under his leadership. Last but not least, he is upgrading capabilities of the team, and that's where market access addition to our team, Chuck Hyde came in and allowing us to fire on all cylinders across both commercial payers, public payers and generating demand from providers. I hope that's helpful.

That's great. And then just for my follow-up, I know we're anxiously awaiting the PRIME data publication as well as some additional data sets. But can you just update us on how conversations have progressed with guideline bodies thus far and where your expectations are at in terms of getting in guidelines at this point?

No, it's a great question. And I assure you, we are exactly where you are eagerly awaiting the publications of all of the results, and we'll keep all of you updated on that. The conversations around PRIME have been incredibly rich, both with the opinion leaders that influence and set guidelines as well as clinicians as well as payers. PRIME study delivered a very rich data set that is exciting for all involved because of the breakthrough results we're seeing. So they're asking us great questions. And the reason it's taking a bit of time is because it required, in some cases, additional analysis of the data set that we were hoping to leave for follow-on publications. But it's exciting that the community is very engaged, very interested and sees how much of a breakthrough saving 1 out of 5 babies from going into the NICU will be in today's day and age when the chances of a newborn ending up in the NICU are multifold higher than they were 5, 10 years ago. Thank you for the questions, Maggie.

Your next question is from Dan Brennan from TD Cowen.

This is William Ruby on for Dan. I guess my first question would be on the EU -- the plan to go to the EU. Just kind of wanted to get a little bit more of your rationale for doing that, just given the large market in the U.S. Is that going to increase cost at all? Just wondering if you could just give some rationale on the EU plan. And I'll just start with that.

William, great question. And for us, the opportunity for global impact has always loomed large, even if U.S. market is absolutely by far the largest in that. That said, over the years, we've engaged with many European opinion leaders at various conferences. And they held up a mirror and said, why are you just focusing on the U.S., we really need it in Europe? And asked us to take our action to Europe as well even before we achieve significant trajectory in the U.S. So we decided to do that and started about 18 months ago working very closely with European opinion leaders in our focus markets because they felt we have a huge opportunity to achieve impact for moms and babies there as well. In terms of your question on additional cost, we're not intending to build out our own large footprint in Europe. We are aiming to and have been in deep discussions with partners across Europe to help us commercialize the test on the ground. So from that perspective, it would be an arrangement that is based on revenue sharing and the cost of commercialization falling on the partner balance sheet and P&L. So from that perspective, we're not anticipating a significant cost increase. We, of course, did need to invest to make the product ready for commercialization. But that we anticipate will have a very high ROI once we begin striking the commercialization partnerships next year.

Got it. And then wondering how many reps you -- I think you said you'd hired some additional reps in like -- in your target regions. Wondering how many reps you've hired in the quarter? And then also just how getting coverage in a few of these high population Medicaid states drive hiring of additional sales reps?

Great question. So we have about a 10% sales force right now and are -- stand ready to hire more as soon as we see traction. Our approach has been, start with creating a fertile ground for reimbursement in particular geographies, and this is why I report the number of states where we see traction. Ideally, by the end of the year, we will see 4 to 6 geographies where that fertile ground of reimbursement has been achieved and staffing those geographies to allow us to drive density of adoption among the providers because, of course, we can share the good news with them that there is reimbursement for the test in their area. That is our approach, and we frequently talked about a waived rollout across states. So as soon as we get good reimbursement context for our sales team and we see traction, we will go ahead and take that commercial model to other states. And our access team is actually reaching out to a much broader set of states to start preparing this reimbursement engagement in additional half a dozen states every 6 months or so. Does that answer your question?

Yes. If I could just ask one more question. Just going back, I think we talked about on the last call, there are some positive feedback with like the ACOG 234 bulletin is talking about -- I think it talked about the need for something preterm birth. I'm just wondering if you had any more positive feedback with that ACOG 234 bulletin from just KOLs or physicians.

So the discussions are not specific to the bulletin that governs spontaneous preterm birth treatment. However, I did, you're absolutely right, speak about the change -- momentous change in ACOG approach, where now ACOG pursues across all of the conditions in pregnancy a tailored approach to care. It's not that it's always been just one size fits all. Of course, there's a differential diagnosis, the physicians treated it appropriately. However, for vast majority of low-risk women in pregnancy, which is the target audience that we address with our test, there was a standard care protocol before. Now with the April announcement that ACOG put out, there is going to be much more -- much deeper integration of tailored care pathways even for what used to be so-called lower-risk pregnancies by using additional risk stratifiers, which, of course, we fit into and therefore, changing care protocols based on those findings and including patients into shared decision-making with the physician, which, of course, was great news for us because for conditions in pregnancy that lead to spontaneous preterm birth that don't typically have clear signs that spontaneous preterm birth could happen. It basically sets the stage for proposing a tool and evaluating all tools in the market where we advantageously stand out because we do have a test with a lot of data validating the test in the clinical utility domain, analytical domain to propose that to physicians. So what was exciting to us was ACOG's movement towards that. And of course, we can't share specific conversations with opinion leaders, but they're all -- they have the eyes on what data we will put out in the coming months so that they can appropriately evaluate inclusion of innovative risk certification tools into this new paradigm of tailoring care to pregnancies that are higher risk and identifying them with new instruments.

[Operator Instructions] There are no further questions at this time. Ms. Lindgardt, please proceed with closing remarks.

Thank you, operator, and thank you all for attending our call today. Over the coming months, we look forward to sharing progress updates and additional data with our medical community stakeholders and Sera shareholders. This data will help us grow our business and Sera's impact on premature birth in the United States and, of course, abroad. We are excited by what lays ahead to take Sera to the next level. I'll now turn it back over to the operator to conclude the call. Operator?

Ladies and gentlemen, this concludes your conference call for today. We thank you for participating and ask that you please disconnect your lines.
