With that taken care of, I'd now like to turn the call over to our President and CEO, Shawn Singh.

Thank you, Mark, and good afternoon, everyone. It's been an important quarter for our team with the completion of the randomized portion of our PALISADE-3 Phase 3 trial in social anxiety disorder as guided and focused efforts to learn from the study's results and drive high-quality and efficient execution of our ongoing PALISADE-4 Phase 3 trial.

We have reviewed available data from Palisade-3 and implemented moderate refinements including retraining, site rationalization, and operational enhancements to PALISADE-4. We have also been working with third-party collaborators on the implementation of innovative approaches to analyze the available data sets not only from PALISADE-3 but also from the fasedienol studies across the PALISADE program, including both the randomized and the open label trials.

Our objective is to better understand the drivers of both fasedienol and placebo response using the substantial data collected from these studies to potentially inform optimized statistical models that consistently incorporate covariates and explanatory variables across all palisade studies, which could anchor future weight of evidence discussions with the FDA.

The analyses are ongoing with our collaborators and involves the use of their proprietary artificial intelligence and machine learning technologies to identify non-specific responses and understand and predict susceptibility to placebo response and likelihood of response to active drug in the context of the public speaking challenge study design.

Overall, the full complement, Of ongoing work is focused on delivering practical operational understanding, predictors of response, and enhanced statistical models with the potential to impact both PALISADE-4 and our regulatory strategy based on the totality of data from the Palisade program. The open label extension portion of PALISADE-3 and PALISADE-4 remains ongoing and is designed to evaluate the safety and tolerability of repeated as needed intranasal administration of fasedienol in adults with social anxiety disorder, but in real world daily life situations.

In addition to safety assessments, the study includes exploratory longitudinal measures using validated instruments such as the clinician administered Liebowitz Social Anxiety Scale (LSAS), and the patient-reported Social Phobia Inventory (SPIN).

While open label data are inherently uncontrolled and exploratory, the OLE portion of the PALISADE-3, phase 3, study could provide important context on patient experience with repeated use over time in real world anxiety provoking situations that patients encounter. Together with our broader analytical work across the PALISADE program, insights from open label studies should contribute to our enhanced understanding of fasedienol’s drug effect and usage patterns.

Once again, we would like to thank the patients who participated in our PALISADE studies, as well as the clinical investigators, the site staff and our contract research organization for their ongoing dedication and professionalism as we complete PALISADE-4 and advance our broader analytical efforts.

As we have previously stated, if PALISADE-4 is successful, together with PALISADE-2 and the broader body of evidence generated across the PALISADE program, these data may support a potential new drug application submission to the US Food and Drug Administration for the acute treatment of social anxiety disorder in adults. The significant unmet need in social anxiety disorder, where effective treatments are very limited, continues to guide our work and our long-term focus.

Turning to our women's health program, we received an official USAN adoption statement designating PH80 as Refisolone. Refisolone is our hormone free, non-systemic intranasal product candidate with potential for the treatment of moderate to severe vasomotor symptoms, commonly referred to as hot flashes, due to menopause. We believe Refisolone may also have therapeutic potential across other women's health indications. We are currently preparing to submit our US investigational new drug application (IND) for Refisolone to the US FDA with a planned submission in the first half of 2026.

This IND is intended to support further potential phase 2 clinical development of refisolone in the US for the treatment of moderate to severe vasomotor symptoms due to menopause. Building on a previously completed placebo controlled exploratory phase 2a clinical trial conducted in Mexico by Ferreon Pharmaceuticals, which is now our wholly owned subsidiary, and that trial demonstrated clinical benefit in the vasomotor symptoms indication.

We believe that indication in women's health represents a significant area of unmet need, and we remain committed to advancing Refisolone as a non-systemic hormone free product candidate with a disciplined, data driven approach as we prepare for the potential next phase of clinical development.

Turning briefly to our financial position as of December 31, 2025, we had $61.2 million in cash equivalents, and marketable securities. During the quarter, we implemented company-wide cash preservation measures intended to enhance our operational efficiency, extend our runway, and maintain strategic flexibility across our PH80 pipeline. We believe we are well positioned to complete PALISADE-4 and to advance preparations and planning for our preparing pipeline.

In closing, our mission remains unchanged to deliver transformative treatments and improve lives. The path forward requires discipline, rigor, and thoughtful analysis, and we believe the steps we have taken and are taking position Vistagen, to make informed decisions and responsibly advance programs with the potential to deliver meaningful value to patients and to shareholders.

So I want to thank you for your continued interest in the company and your support, and we look forward to updating you on our progress in the quarters ahead.

Thank you, Shawn. Operator, we would now like to open up the call for questions from the call side analyst joining us today.

(Operator Instructions). The first question today is coming from the line of Andrew Tsai, Jefferie's.

Hi, good afternoon. Thanks for the updates. So, maybe in the PALISADE-3 data you had a chance to look at it, maybe descriptively, how did the individual curves look at every interval out to five minutes? Was there a separation at all across any of those time points, with fasedienol versus placebo?

Thanks for the question, Andrew, Josh?

Hi Andrew, we at this point, you know, what we have released publicly is the top-line results so we're still looking into a lot of that data we have not released the individual curves publicly. We do know that there's what really, where we find information is looking into individual, respondents and subgroups of respondents, and again that analysis continues, so that's where we do see definite differences.

Okay, thanks, and it sounds like you're looking at ways for Palisade 4, to tweak around the SAP plan and let's just say you did, would you need to notify and then talk to the FDA, to potentially get an official buy-in from them that the changes can be done? Is there a risk to modifying the SAP plan basically? Yeah, thank you.

We would great question. Oh, go ahead.

That's Yeah. It's a great question, and you know, the SAP, just like with PALISADE 3, already been submitted and approved for no feedback from FDA. So any future changes to your point would absolutely require, a resubmission and alignment with the FDA before we locked the database and got the top-line results.

Understood. And then my last question, thank you. Should you modify the plan, would you need to backfill to back to the original enrollment target of around 236 or 238, or are there no changes to the enrollment?

Yeah, the change to the SAP would not change, the enrollment or the planned enrollment for the study. You know it's the key there is that it's whatever that SAP, is like I said locked in before you get to database lock, and then applied to the total, population for the study.

Understood. Okay, thank you guys.

Thank you. Emily, Stifel.

Hi, this is Emily on for Paul at Stifel. We just had a quick question. Maybe could you remind us where you guys are in with in terms of enrollment. For PALISADE-4, and if you like plan on telling if, or plan on ping when t hat has completed or like dosing has completed and then also could you maybe share him like what details you saw on PALISADE-3 that kind of led you to refine to the refinements that you outlined in the PR. Thank you.

Thanks, Emily. Appreciate the question. So, it'll be consistent with the pattern for PALISADE-3, once we hit the last patient's last visit and then proceed towards top-line. So, that'll be, we are on track with guidance that we have previously given, with respect to PALISADE-4 TLR, the randomized portion of PALISADE-4. Joshua, you can address the second part.

I'm sorry, I missed the second part. Can you rephrase that?

For, you guys discussed like refinements and including like retraining of some sites, could you maybe provide any color on what details you saw from PALISADE-3 that kind of led to that decision?

Yeah, I do not think we ca not go into too much detail given PALISADE-4 is ongoing, but at a high level, one of the things that made PALISADE-3 different than PALISADE-2 was a higher placebo response. So, as one example, making sure that our training is reinforced and up to date with sites in terms of. Potential ways to minimize that, in particular, kind of how the protocol is followed, the script is followed to the letter.

Making sure that there is no, you know, chatting with subjects as they come in, anything that could potentially lend to, a comfort for a subject or that could drive a higher placebo effect. So it is those types of things that we are able to implement quickly based on what we see from PALISADE-3 and also because we are listening to what is happening at each site. Through the audio recordings that we have talked about previously gives us the opportunity again to be hyper focused, on feedback and, any intervention where we see something deviating from the.

Great. Thank you guys so much.

In addition to that, some focus on centralized recruitment and making sure that gets and stays completely tight and rationalized. So the kinds of things that can impact in-stream execution, especially, as Josh noted, with with high focus on placebo mitigation strategies and best practices across, especially from the really experienced sites.

Thank you. Myles Minter, William Blair.

Hi team. This is John on for Myles. Thanks so much for taking our questions. Was wondering if you could talk a little bit more through your regulatory path forward and your confidence in it, in the event that PALISADE-4 hits and you have a 50% program success? And alternatively, if PALISADE-4 misses, do you see any, regulatory path forward with PALISADE-2 alone?

Thanks, John. I appreciate the question. So, look, they, Fundamentally we believe that the regulatory outcomes always depend not only on FDA regulations and guidance, but the totality of data, the weight of evidence, the risk benefit, the nature of the the in need population. So these kinds of assessments, this is what we align our regulatory strategies to accordingly. So we are not really in a position to speculate on any approval scenarios, but what we can tell you, of course, is we are very mindful not only of the evolving. The way that AI is evolving within the agency and how that is emerging is part of and factoring into the regulatory decision making.

We on top of that and very closely focused on that, but also just again the weight of evidence once we see where we are with the randomized portion of PALISADE-4, we will be able to look across the totality of the program and the primary objective and the primary regulatory strategy remains as we have said, which is. Complementing, if PALISADE-4 is successful, complementing PALISADE-2 with a broader base of information from the totality of the program for the acute treatment, of social anxiety disorder. If PALISADE-4 does not hit and separate from placebo, it is still the same. It is a totality of evidence focus.

It is a weight-of-evidence focus across the program and what we see from all data we can possibly see and analyze relating to the drug.

Helpful. Thanks. And a quick follow-up. Is there anything that you are seeing in the blinded data of PALISADE-4 that gives you a little bit more confidence in that study over PALISADE-3?

You don't comment on the blinded data, John.

All right, thank you. Elemer Piros, Lucid.

Yes. Good afternoon. Shawn, have you noticed any impact on enrollment since the announcement on December 17, enrollment patterns?

Josh, you can address that.

Sure. The quick answer is no. Definitely have not. Enrollment has continued as planned and projected for PALISADE-4.

What I am trying to understand is how could the PALISADE-3 outcome and potentially PALISADE-4, be different by amending the SAP. Would that mean that it would include some covariates that may influence the separation? Between the two arms, if you could just help me conceptually understand this a little bit better.

Sure, I mean, part of what we are doing with AI and machine learning, it is potential, it is not certainly not guaranteed, and if they are what you are looking for is, are there any covariants that may have a potential fixed effect on the ANCOVA. And that's, that may or may not evolve and emerge from the work that we are doing with our collaborators with their proprietary AI and ML. But it would be those kinds of things. Are there covariates that you notice when you look through, the patient populations in each arm in prior studies, in PALISADE-3 in particular that may give you some sort of signal. So, The answer is we do not know yet, and as noted earlier, if we do make a modification to the SAP that is already been signed off by the agency, then we'd have to go back to them and and socialize it with them.

So, that is part of what we are trying to find out. If there is not, then again we have got operational, efficiencies and observations based on what we have seen across the studies that are being, implemented into the PALISADE-3 or PALISADE-4 execution. Josh, anything you want to add on that from the teams?

Yeah, I think that that captures it.

So just to summarize, you are looking at PALISADE-3 and maybe even PALISADE-2 for some covariates. If you find them, then you modify the SAP. Take it to the FDA before you were to analyze, I would say, four, hypothesizing that those same covariates will be applicable to PALISADE-4. Am I understanding it correctly?

Yeah, it has to be whether correct. Not only whether it is timely. It has, like, obviously got to be timely before you lock the database, but it is also got to be appropriate and there may also be potential changes that would not be FDA regulatory appropriate. So it is got to be something that could be impactful at the same time something that is reasonable with rigor and review from the FDA.

And Shawn, I just said that we are actually. It has, like, looking across all the PALISADE studies, so PALISADE-1, PALISADE-2, and PALISADE-3 to see what we can learn, we have built, now that we have had a third study complete, we have built, continued, size of, data to examine which gives you more power when you are digging into, different things. But you are 100% correct that it is essentially the covariates or the correction factors that you would apply in your statistical model.

I understand. And just a silly housekeeping question, if you may, if I may, at the end of December, you had $39.7 million shares outstanding, but the weighted average for the quarter was 42. Can you help me to understand that?

Nick, are you on? Hi.

Yes. I am. Yeah. So it is the shares outstanding at the end of the quarter. It is how we measure our earnings per share.

Okay. So Shares out there. But so, but there are higher number of shares outstanding, because the average is $42 million.

It's that includes the prefunded warrants, Elemer.

I got it. Okay, yes, thank you so much for clarifying that.

Not a silly question.

Operator, I believe that's all the time we have for today. We can wrap up the call. So, thank you everyone for joining us today and for your continued interest and support in Vistagen. Again, with our diverse innovative pipeline, we are encouraged about the future prospects of the company.

We also encourage you to register for email updates and stay informed.

About the latest news and developments from Vistagen via our regular updates. We appreciate your time, engagement, and ongoing support, and we look forward to keeping you updated on our continued progress. This concludes our call today.

Mark. One more thing real quick, I just want to clarify I think I misspoke. It's, I think I said $61.2 million at the end of 12/31/25. It was $61.8 million is reflected in our 10-Q.

Understood.

Thanks, Shawn. Thank you.

Thank you.

This concludes today's program.

Thank you all for joining. You may now disconnect.
