Thanks, Walter, and thank you to everyone joining our call this evening. I'll start by reviewing some of the highlights of our operations and financial results during the fourth quarter and full year before turning the call over to our Chief Financial Officer, Diana Diaz, for a more detailed look at our financial results. We'll conclude by opening the call for a brief Q&A. For the full year, we reported $34.7 million in sales. While we saw a decrease in our sell-side revenue during the year, we grew full year buy-side revenue, maintained strong gross margins for the year and importantly, drove considerable efficiency and cost reduction in the business. Finally, we made significant strides in improving our balance sheet. We still have a lot of work to do, but I'm encouraged that many of our strategic initiatives position us very well as we move into 2026. We're a focused, more nimble organization with a realigned structure and a clear strategy to drive returns for shareholders. Over the past 1.5 years, we've noticed a shift to the overall digital advertising market that prioritizes buy-side transactions as well as increasing demand from our customers for more accessible buy-side media. During 2025, we began to lean into this demand, resulting in increased buy-side revenue, which offered some early confirmation from what we're seeing in the market. Fast forwarding to where we are today, buy-side revenue grew 28% in the fourth quarter of 2025 compared to the fourth quarter of 2024, and has increased 10% year-over-year, supported by a combination of new and existing customers and the demand we're seeing across our verticals, including travel and tourism, higher education and energy to provide a few examples. As we move through 2026, we'll continue to increase our focus on driving more digital marketing spend…

Thank you, Mark, and good evening, everyone. I'll now provide a review of our fourth quarter results with some context on full year trends were relevant. Consolidated revenue in the fourth quarter of 2025 was $8.4 million compared to revenue of $9.1 million in the fourth quarter of last year. Buy-side revenue increased approximately 28% to $8.2 million compared to buy-side revenue of $6.4 million in the fourth quarter of last year. Sell-side revenue was $200,000 in the fourth quarter compared to $2.7 million in the fourth quarter of last year. The decrease in sell-side advertising revenue was primarily related to a decrease in impression inventory when compared to the fourth quarter of last year. Gross margin for the fourth quarter of 2025 was 27% compared with 32% in the fourth quarter of last year. Operating expenses in the fourth quarter of 2025 and were $6.7 million, a decrease of 12% compared with $7.7 million in the same period of last year. On an annual basis, operating expenses decreased 18% to $25.2 million for the full year of 2025, a decrease of $5.4 million compared with operating expenses of $30.6 million in the full year of 2024. Expense reduction remains a key strategic priority and we're pleased with the progress achieved in 2025. Total operating loss for the fourth quarter was $4.5 million, consistent with the fourth quarter of 2024. Net loss for the fourth quarter was $12.6 million compared to a net loss of $6.6 million in the fourth quarter of last year. This year's quarterly net loss included nonoperational financing-related costs of $7.4 million. Adjusted EBITDA for the fourth quarter of this year was a loss of $3.6 million compared with adjusted EBITDA loss of $3.4 million in the fourth quarter of last year. Turning to the balance sheet. We ended the quarter with cash and cash equivalents of $700,000 compared to $1.4 million at the end of last year. Total cash plus our accounts receivable balance as of December 31, 2025, was $3.9 million compared to $6.4 million at the end of last year. Throughout the quarter and the year, we've taken several steps to enhance our balance sheet. [Technical Difficulty]

Ladies and gentlemen, please stand by while we work through our technical difficulties. Ladies and gentlemen, thank you for your patience. We are now reconnected. Ms. Diaz, you may continue.

Okay. Thank you. Adjusted EBITDA for the fourth quarter was a loss of $3.6 million compared with adjusted EBITDA loss of $3.4 million in the fourth quarter of last year. Turning to the balance sheet. We ended the quarter with cash and cash equivalents of $700,000 compared to $1.4 million as of the end of last year. total cash plus our accounts receivable balance at the end of December 31, 2025, was $3.9 million compared to $6.4 million at the end of last year. Throughout the quarter and the year, we've taken several steps to enhance our balance sheet, our capital structure and our access to capital. In the third quarter of 2025, we announced the issuance of $25 million of a new series of convertible preferred stock through the conversion of a portion of existing debt into the new class of perpetual convertible preferred stock. In the fourth quarter, we issued an additional $10 million of Series A preferred stock and expanded our equity reserve facility by 50 million shares or $100 million. We raised a total of $7.3 million through the equity reserve facility in 2025. And on December 30, 2025, our Board of Directors and shareholders approved a 55:1 reverse stock split of all classes of our common stock which was implemented on January 8, 2026. With that said, earlier today, we filed an 8-K to disclose a receipt of a listing deficiency notice from Nasdaq regarding our stockholders' equity as of December 31, 2025, as reported in our Form 10-K, which we filed last week. We're working closely with our team and advisers on next steps intended to bring us back into compliance, and we will provide material updates as they become available to us. As we said before, our Nasdaq listing is a key asset that provides heightened visibility among institutional investors, which is foundational to our go-forward strategy to build and maintain a strengthened investor base. We will continue to prioritize our listing on Nasdaq and evaluate and take the necessary steps to preserve our status. And now I'd like to turn it over to Mark for some closing comments.

Thank you, Diana, and thank you to everyone for joining. We appreciate your interest in Direct Digital Holdings. I would like to now open the call for questions. Operator, please open the line.

[Operator Instructions] And our first question comes from the line of Dan Kurnos with Benchmark, a StoneX company.

I guess, I'll keep it quick here and just ask how should we think about the sell-side at this point, wind down, deemphasized, utilize your data? And then subsequently, on the buy-side, as you guys pivot, just curious, as you think about channel expansion, COGS was up. You mentioned kind of your key priority categories was the specific categories, travel, the primary driver? Were there some ancillary categories that added? And just how do we think about your ability to scale up from the current base level based on the Q4 results.

Yes. Good question. Yes, twofold. One, the way we think of the sell-side business is really is a margin capture opportunity. As we've talked about before, we have moved more towards a unified structure where we leverage as much and try to run as much as we can of the buy-side demand dollars into our sell-side platform to the benefit of our customers. So I would view it as more of a margin capture strategy, which helps us capture an extra 20% to our bottom line with more -- that flows through there. As it relates to how should we think about expansion and growth and growth accelerants, the expansion into new verticals is important to us. So as you know, Dan, since you've been following us for a while, the DMO/travel tourism space or regional and local travel tourism space is important to us, definitely a strong segment that we're continuing to see growth and opportunity there. In addition to that, the education space has been strong for us with some of the educational clients that we've brought into the fold. The third that we have had a heavy focus in is the energy sector, which is a new category that's helped us grow. We believe with the headwinds of the macroeconomic view that, that mix is a stable mix for our company and is 1 that we're going to continue to expand and lean into on a go forward. In addition, for growth strategy, we're also exploring inorganic opportunities on the demand side of the business where we feel like we have a real opportunity to add on new verticals.

And just, I guess, as we think about new sources of revenue, obviously, right now, the space is super focused on the buy-side anyway on getting away from sort of the legacy DB Plus focused on CTV. You've got a bunch of DSPs focused on trying to drive dollars away from social and SMB is a huge talking point. You clearly have a lot of regional and smaller buyers. I understand you're not a DSP yourself, but I mean that seems to be where the buy-side is focused. I wonder if you guys can kind of tap into the trends that are going on in the space right now?

No. I think we've been ahead of the trend in the mid-market space. I think you're starting to see more and more players. As you know, some of the larger guys starting to move down into the mid-market space where we have a strong foothold, specifically in those Tier 2, Tier 3 media markets. So we're going to continue to expand there. We think that the opportunity we have, which allows us some flexibility as the opportunity to do that organically, which we've historically have proven that we can do. And I think we also are looking at inorganic opportunities that add different regions into our mix as well. We do believe that similar to what other people are saying, yes, we think that the fact that we're able to service social as well as programmatic is important to us, and we're going to continue to focus in on both of those.

And our next question comes from the line of Michael Kupinski with NOBLE Capital Markets.

First of all, congratulations on seeing the acceleration in the buy-side revenue. That's very encouraging. I was just wondering if you can just break down the sustainability of that 28% buy-side growth in Q4? You mentioned that it was driven by new customers and expansion with existing accounts. I was just wondering if you can just share with us how much was driven by the new customers versus the existing accounts?

Yes. In regards to new customers, I don't have that number off the top of my head on the specific percentage. But I can say that what we are seeing is with the new mix of customers that we have brought in, specifically in the energy sector, it is helping to change our typical curve that we have seen where we used to have the tail off between 3 and 4. Now we're seeing where it's starting to maintain within quarters 3 and 4. And so we anticipate that we're going to see that same type of curve within 2026. And that's really driven mostly from new customers that we brought into the fold for us.

And just to clarify, Michael, the fourth quarter included $1.7 million from customers in new verticals. And for the year, we had -- hold on to that number. But that was the fourth quarter was $1.7 million. It was about $7 million for new customers for the year.

For this year. That's terrific. And then how scalable is the current buy-side platform? And is there -- are there any bottlenecks to see some acceleration in the growth there? If I know you've main seeing some pretty decent margins there. I'm just wondering how sustainable those are?

Yes. So we're -- as we said before, we have actually more cost saving measures that are going to come into fold that we should see the benefit in Q2, which we're looking forward to, to help expand our margins some. We do believe that the buy-side still has more upside growth potential for us in regards to the expansion on current customers and the growth that we're seeing from them and then also new customers that we're bringing into the fold. So do we think we can maintain a trend? Yes, we think Q1 is going to be positive growth as well. And we still hold to on an annualize basis of 10% growth over year-over-year is what we're focused in on.

Got you. And then in terms of the traction or KPIs, can you kind of give us share us your thoughts about ignitions in the AI platform since its launch? If you can just give us some sense of what KPIs are you looking at there?

Yes. We're looking for large enterprise customers that we could bring in specifically under that program. We view it as more sizable, larger than our current average revenue per customer that we bring in on that, and we run test pilots within 2025 that we're hoping to come in fruition as full blown customers within 2026. The KPIs that we look for there are going to be larger spend ratios that come from them at a more shared margin opportunity for them due to the transparency.

Got you. And then you were speaking about inorganic growth going back to the buy-side, what kind of verticals are you looking at that would be interesting to you to add beyond the current scope of what you currently have in your verticals?

Health care is 1 that we're definitely have a keen eye on as well as some CPG to move us more in the retail space on those verticals as well. And then financial services, banking services is the other one.

Got you. And then you said that you're taking additional steps to reduce costs. Can you kind of just talk us through about what those additional steps might be? And if there's a dollar amount you might be able to put around that?

Yes. Diana, would you like to take that one?

Sure. So some of the cost reductions that we're looking at had been historically on the sell-side, and we have some contracts that are winding down in that business that we think we can live without. And so that's the bulk of it, it's probably starting in the second quarter about $0.5 million a quarter reduction.

And that concludes our question-and-answer session. I would like to now turn the conference back over to Mr. Mark Walker for closing remarks.

Thank you. That concludes our conference call for today. Thank you for participating. You may now disconnect.

Ladies and gentlemen, once again, this concludes today's call. We thank you for your participation, and you may now disconnect.
