Good morning, ladies and gentlemen, welcome to Prosperity Bancshares’ fourth quarter 2025 earnings conference call.

All forward-looking statements are expressly qualified in their entirety by these cautionary statements. Let me turn the call over to David Zalman.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Thank you, Charlotte. We had a stellar quarter. I would like to welcome and thank everyone for listening to our fourth quarter 2025 conference call. For the year ended December 31st, 2025, we had net income of $543 million compared with $480 million for the same period in 2024, an increase of $63 million or 13.2%. Our net income per diluted common share was $5.72 for the year ending December 31st, 2025, compared with $5.05 for the same period in 2024, an increase of 13.3%.

The net income was $139.9 million for 3 months ending December 31, 2025, compared with $130 million for the same period in 2024, an increase of $9.8 million or 7.6%. Our annualized return on average assets and average tangible common equity for the 3 months ending December 31, 2025, were 1.49% on assets and 13.61% on tangible equity. Prosperity’s efficiency ratio, excluding the net gains and losses on the sale, write-down or write-up of assets and securities, was 43.6% for the 3 months ending December 31, 2025. As mentioned since 2024, we expected our net interest margin to increase, and it has.

The net interest margin on a tax equivalent basis was 3.3% for the 3 months ending December 31, 2025, compared with 3.05% for the same period in 2024, compared with 3.24% for the 3 months ending September 30, 2025. During the year ending December 31, 2025, under its 2025 stock repurchase program, Prosperity Bancshares repurchased approximately $157 million, or 2.34 million shares of its common stock at an average weighted price of $67.04. Our loans, excluding warehouse purchase program loans, were $20.5 billion at December 31, 2025, compared with $20.7 billion at September 30, 2025, a decrease of $249 million.

We continue to see good demand for loans. We are not willing to compete with the terms and conditions being offered sometimes by out-of-state competitors on some of the larger deals. Our overall loans have been impacted by efforts to outsource some less desired loans acquired in previous transactions also. As mentioned in our last quarter, we expected deposits to increase due to seasonality, the increase exceeded our expectations. Deposits were $28.4 billion at December 31, 2025, an increase of $700 million from $27.7 billion at September 30, 2025. Our non-performing assets totaled $150 million, or 46 basis points of quarterly average interest-earning assets at December 31, 2025, compared with $119 million or 36 basis points of quarterly average interest-earning assets at September 30, 2025.

The increase in outperforming assets during the year was primarily compromised of two loans made in our middle market lending group and one well-collateralized real estate loan acquired in one of our recent acquisitions, all of which Kevin will be able to answer and address in the Q&A. The allowance for credit losses on loans was $333 million, and the allowance for credit losses on loans and off-balance sheet exposure was $371 million as of December 31st, 2025. Our allowance for credit losses on loans still stands strong at 2.21 times of our non-performing assets. I’m excited to announce that on January 1st, 2026, Prosperity completed the merger with our new partner, American, and its wholly owned subsidiary, American Bank, headquartered in Corpus Christi, Texas.

In connection with that transaction, we are pleased that Patt Wallace, the daughter of one of the founding families of the bank, and Steve Retzloff, the CEO of American Bank, have joined our bank Board of Directors. We have also received all the regulatory and shareholder approvals for the merger with Southwest Bancshares, the parent company of Texas Partners Bank, and expect the transaction will be effective on February 1, 2026. In connection with the Southwest deal, we are pleased that Gene Dawson, Jr., Interim Chairman of Southwest Bancshares and Chairman of the nationally recognized Pape-Dawson Engineers firm, will be joining our bank Board of Directors. To further add to our San Antonio presence, Charlie Amato has joined our bank Board of Directors.

In addition to his successful business, Charlie previously served as a board member of the Federal Reserve Bank of Dallas San Antonio Branch and regent of the Texas State University System, and is an investor in the San Antonio Spurs. There, there’s much more, but it’d be too much more to go over with all he’s into. When Prosperity went public in 1998, we were a small community bank in rural Texas with less than $500 million in assets. For 27 years, we have remained disciplined and focused on the same strategy, delivering shareholder value by prioritizing. Low cost core deposits, operational efficiency, sound credit quality, and growth via opportunistic M&A. This morning’s announcement that Prosperity is acquiring Stellar Bancorp is consistent with that strategy, and this transaction marks an important milestone for the company.

Our combined Houston bank deposit rank goes from number nine to number five, making us the largest Texas-based bank in the market and second-largest bank by deposits in the state. Importantly, Stellar is a well-run bank with similar credit discipline and an envious non-interest-bearing deposit mix. As a result, we view the transaction as a low-risk combination that significantly enhances our Texas footprint. I would like to thank all our customers, associates, directors and shareholders for helping build such a successful bank. Thanks again for your support of our company. Let me turn over our discussion to Asylbek Osmonov, our Chief Financial Officer, to discuss some of the specific financial results we achieved. Asylbek.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Thank you, Mr. Zalman. Good morning, everyone. Net interest income before provision for credit losses for three months ended December 31, 2025, was $275 million, an increase of $7.2 million compared to $267.8 million for the same period in 2024, and an increase of $1.5 million compared to $273.4 million for the quarter ended September 30, 2025.

The net interest margin on a tax-equivalent basis was 3.30% for the three months ended December thirty-first, 2025, an increase of 25 basis points compared to 3.05% for the same period in 2024, and an increase of six basis points compared to 3.24% for the quarter ended September thirtieth, 2025. Excluding purchase accounting adjustments, the net interest margin for the three months ended December thirty-first, 2025, was 3.26% compared to 3% for the same period in 2024 and 3.21% for the quarter ended September thirtieth, 2025.

Fair value loan income for the fourth quarter in 2025 was $3.1 million compared to $2.9 million for the third quarter in 2025. The fair value loan income for the first quarter 2026 is expected to be in the range of $3 million-$4 million. Non-interest income was $42.8 million for the three months ended December 31, 2025, compared to $41.2 million for the quarter ended September 30, 2025, and $39.8 million for the same period in 2024.

Non-interest expense was $138.7 million for the three months ended December 31, 2025, compared to $138.6 million for the three months ended September 30, 2025, and $141.5 million for the same period in 2024. For the first quarter of 2026, we expect non-interest expense to be in the range of $172 million-$176 million. This projection includes three months of American Bank expenses and two months of Texas Partners Bank expenses. In addition to this first quarter guidance, we will also have about $30 million-$33 million in one-time merger related charges for those two acquisitions.

We expect to realize most of the previously announced cost savings related to American Bank and Texas Partners Bank after the system conversions, which are scheduled later this year. The efficiency ratio was 43.7% for the three months ended December 31, 2025, compared to 44.1% for the quarter ended September 30, 2025, and 46.1% for the same period in 2024. The bond portfolio metric at 12/31/2025 have a modified duration of 3.7 and projected annual cash flows of approximately $1.9 billion. Let me turn over the presentation to Tim Timanus for some details on loan and asset quality.

H.E. Tim Timanus Jr., Chairman, Prosperity Bancshares: Thank you, Asylbek. Our non-performing assets at quarter end December 31, 2025 totaled $150,842,000, or 69 basis points of loans and other real estate, compared to $119,563,000, or 54 basis points at September 30, 2025. This is an increase of $31,279,000. Since December 31, 2025, $6,631,000 of non-performing assets have been removed or put under contract for sale. The December 31, 2025 non-performing asset total was made up of $137,534,000 in loans, $12,000 in repossessed assets, and $13,296,000 in other real estate.

Net charge-offs for the three months ended December 31st, 2025 were $5,884,000, compared to net charge-offs of $6,458,000 for the quarter ending June 30th, 2025. This is a decrease of $574,000 on a linked quarter basis. There was no addition to the allowance for credit losses during the quarter ended December 31st, 2025. In addition, no dollars were taken into income from the allowance during the quarter ended December 31st, 2025. The average monthly new loan production for the quarter ended December 31st, 2025 was $314 million, compared to $356 million for the quarter ended September 30th, 2025.

Loans outstanding at December 31, 2025, were approximately $21.805 billion compared to $22.028 billion for September 30, 2025. The December 31, 2025, loan total is made up of 35% fixed rate loans, 35% floating rate loans, and 30% variable rate loans. I will now turn it over to Charlotte Rasche.

Charlotte Rasche, Executive Vice President and General Counsel, Prosperity Bancshares: Thank you, Tim. At this time, we are prepared to answer your questions. Our call operator, Gary, will assist us with questions.

Catherine Mealor, Analyst, KBW3: We will now begin the question and answer session. To ask a question, you may press star then one on your telephone keypad. If you are using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star then two. The first question is from Catherine Mealor with KBW. Please go ahead.

Catherine Mealor, Analyst, KBW: Thanks. Good morning.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Good morning.

Catherine Mealor, Analyst, KBW: I wanted to start just on the Stellar acquisition. Congratulations on that. I noticed in the slide deck you’re using a different estimate for Stellar versus consensus. Looks like it’s about a 220 number versus $2.00 for consensus roughly. Just curious what’s driving that difference and your confidence in that level of earnings coming over from Stellar. Thanks.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Catherine, you probably saw their fourth quarter earnings come out. That’s really gonna influence that. Paul’s here with us today from Stellar, and I’ll let him go over it with you.

Catherine Mealor, Analyst, KBW4: Absolutely.

Catherine Mealor, Analyst, KBW: Okay, great.

Catherine Mealor, Analyst, KBW4: Thanks, Catherine.

Catherine Mealor, Analyst, KBW: Hey, Paul.

Catherine Mealor, Analyst, KBW4: We’ve been thrilled with our growing momentum in the back half of 2025 and what that portends for 2026. We’ve been able to grow our earning assets in the back half of the year pretty meaningfully, all while maintaining and growing our core NIM, and that paints a great picture for 2026. We actually feel great about the momentum we’re taking from a growth perspective into 2026 as well. If you were to take 2024 just, or pardon me, the fourth quarter just to be simplistic, and put a kind of more normalized provision onto it and annualize it, you’d be talking about $0.50-$0.55 per share EPS run rate, which would annualize to $2.20.

We enter 2026 with about $100 million more in interest earning assets than our average for the fourth quarter of 2025. That’s gonna be help assist us, and then we’ll have the first kinda full quarter benefits of the rate changes, the Fed rate cuts that occurred in the fourth quarter. All that paints a really good picture for us to maintain and actually upside to the go-forward earnings run rate. I think the last point I’d note is we assume a more normalized consensus level of net charge-offs, and both us and Prosperity have a great track record of delivering meaningfully lower net charge-offs, which would mean, which would drive lower levels of credit costs and potential beats to the numbers we put forth.

Catherine Mealor, Analyst, KBW: Okay. Very helpful. Thank you. Then, as we think through, you know, growth moving forward. It looks like part of that is assuming better growth at Stellar, which is great. You typically, from Prosperity, what we’ve seen with past deals is you do an acquisition, then you shrink a little bit, and that’s been part of the headwinds that we’ve seen at growth at Prosperity recently. Why is this acquisition different? What kind of forecast for growth in 2026 should we expect for Prosperity? Thanks.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: I think this is different. We’ve Bob and I have known each other for 10 years plus. There, again, we’re across the street, so we can throw rocks at each other. To me, it takes a lot of risk out of a transaction like this, I think. We’ve talked about doing this for a lot of years. It makes a lot of sense. I think there will be efficiencies through this. I would say, as far as growth going forward in 2026, I would say that our plate is pretty full with the transactions that we have. I think that we’re gonna primarily focus on the integration of the 3 banks that we have.

Having said that also, I think the Stellar Bank is very much like our bank. With some of the banks that we buy, we know that either their deposits are extremely high or their loans or something else wrong, and we have to get rid of them. I don’t see that in the Stellar acquisition. I think that they’re very similar to us. I feel good about that. Again, I think our focus is really gonna be taking care of our customers, taking care of our associates, and actually putting all these three deals together this year. That’ll be our main focus.

Catherine Mealor, Analyst, KBW: Okay. Understood. Thank you.

Catherine Mealor, Analyst, KBW3: Our next question is from Manan Gosalia with Morgan Stanley. Please go ahead.

Catherine Mealor, Analyst, KBW1: Hi. Good morning, all.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Good morning.

Catherine Mealor, Analyst, KBW1: David, maybe, can you help us think about the price of the acquisition? You know, 18 times one year forward does feel a little high, but, you know, I know you mentioned the higher level of NIB and the synergies. Maybe if you can help us appreciate, you know, all the synergies and growth prospects that the combined banks have. Also, you know, how you think through the earn back period, 4.5 years, earn back is a little bit higher than what you’ve done recently.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: You know, I could start off in saying, I think, this, I don’t know if this is a good analogy or not, but I think banks are a lot like cars. You know, I can drive a Ford Pinto, or I can drive a Range Rover. The Pinto will probably get me wherever I need to go, and I can probably throw it away and not lose a bunch of money when it’s gone, or I can really enjoy and have a Range Rover that’s gonna really be something and have a good resale value. This, you know, there’s a big difference in the price of things, and I think some people have a harder time doing that. Every, a bank that’s good deserves a premium price. These guys, it’s just, it’s a premium bank.

The thing that we really look at is, you know, we say the price, but I look at it and I say, okay, in 2027, our combination will be earning $7.34 a share once we get all of this put together. So at $7.34, if we trade just at 13 times earnings, our, you know, our stock value would be $95.42. If we traded at 15 times earnings, and then somebody may say, "Well, that’s high." Well, I would just tell you, the first bank in Colorado went for that much.

You saw these other banks. I can tell you, I could call up any one of the mid-sized banks underneath Bank of America or JP Morgan, the guys underneath them, they would offer us 15 times earnings probably in a New York minute, which would indicate a price, a value of our bank at least at $110 a share. We paid a lot for it. I would tell you, too, that it should be easy for anybody to see that the franchise value, not only is it accretive, but the franchise value is really enhanced by us being one of the largest banks in the Houston market. I think the combination of the earnings, the enhancement of the franchise value, and that’s what sometimes

I don’t know how do you put a price on the enhanced franchise? I can tell you it’s significant, and I think that anybody would want to probably acquire us as being one of the bigger banks in the state of Texas and the franchise that we have. That’s, that’s kind of the rationale behind it. It also, you know, it takes us from being a, these, all three of these deals, it takes us from having a 13% return on tangible capital. I mean, we’re looking at a 17% on return average tangible capital in the year 2027. Not only did I like it, not only is it pretty, the metrics make sense for all of these deals. That’s kind of the rationale.

Catherine Mealor, Analyst, KBW1: Got it. That’s helpful. Maybe as you think about the capital deployment strategy from here, I guess you’re now integrating three deals together. Is that it for now? Would you focus on the integration for the coming months? Just given where the stock price is there more of a focus on buybacks? I know you guys upped the authorization yesterday, maybe just help us think through capital deployment plans from here.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Well, let’s say we’re going to do any more deals, they’ve got me handcuffed in this room, so I can’t get out. You know, if you can look at the projections going forward in the year 2027, I think we’re projected to make around $880 million. We have about 120 million shares outstanding, and you can do the math. We’re paying $2.40 a share in dividends. That’s $288 million or so. I think that’s right. You subtract that 288 from 680, you know, we have about $600 million. We have a not only do we have a strong capital to begin with, we have just like a, I mean, like a printing press.

You know, if something doesn’t go wrong with $600 million, we can do a lot with that. We can buy a lot of stock back, we can increase dividends, and we can buy more banks. It’s a high-class problem.

Catherine Mealor, Analyst, KBW1: I guess, any immediate priorities there? Like, would, so would you tilt more towards buybacks in the near future?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: I think that when it’s opportunistic, we certainly would look at buybacks for sure. We just as this last year, our stock went down in the 60s, the low 60s, and I think you saw where we spent $157 million on buybacks this last year. I think we have another 5% approved for this year. You’re talking, what’s that, $300 million that we can buy back this year as well, and that’s been approved already by the Fed.

Catherine Mealor, Analyst, KBW1: Got it. I appreciate it. Thanks so much.

Catherine Mealor, Analyst, KBW3: The next question is from Stephen Scouten with Piper Sandler. Please go ahead. Mr. Scouten, your line is open on our end. Perhaps it is muted on yours. Moving on, the next question is from David Chiaverini with Jefferies. Please go ahead.

David Chiaverini, Analyst, Jefferies: Hi. Thanks for taking the question. You mentioned about, you know, you’ve got multiple bank integrations occurring simultaneously. Can you talk about ways you’ll be able to juggle these at the same time and not get distracted from the core operations?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Well, again, they’re all planned, somebody may wanna talk about which ones we have in order, but, I mean, we’ve done 40 of these transactions, so I don’t think this is gonna be. There may be 3 of these, but again, we’re doing our own operational integration here probably in the next few weeks or so.

David Chiaverini, Analyst, Jefferies: Yeah.

Right after that, we’re going into American Bank, dated, what, also back then.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: I think, specific to address the question, we have designated teams who does that. It’s not like our people who is out on the field doing the, you know, organic growth. They’ll be focused on this. We have specific team focusing on integration. We have a plan to convert these banks, those two bank, American Bank and Partners Bank this year in the sense of integration. In the process so far, it’s going well. We started in advance, so it’s not like we’re starting now. We are scheduled to do conversion later this year, and it’s working as we planned.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: We feel confident where we’re at. It’s not to say that you won’t ever have any glitches on anything that you do. There always may be something like that, for the most part, we have a well-seasoned team that’s done many of these things, and they feel very comfortable where we’re at.

David Chiaverini, Analyst, Jefferies: Great. Thanks for that. Can you talk a little bit about the cultural fit? How did the deal come together, and why now with the deal?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Well, the time seems to be right. I mean, if you look in the previous administration, I think we were trying to do some bank deals and even much smaller deals. I think the last bank we took, I may be wrong, but it took us almost 1 year to get completed. I think that from a regulatory standpoint, that the regulatory things are in place to make this happen. The timing is right, and, you know, it was right. I think it was right for us, I think it’s right for them. It just seemed to be the right time.

David Chiaverini, Analyst, Jefferies: Can you talk about the cultural fit and how the deal came together?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Yeah. I mentioned earlier, Bob and I have known each other for 20 years or more. I mean, I would say. I said this in our meeting the other day. I said, "If I got killed and ran over tomorrow and Bob took my place, I don’t think that, I don’t think that our bank would change, our combined bank would change at all." I think that, if anything, I think they may be even more conservative than we are on the loan side. That’s hard to believe. So we feel we did our due diligence, and we feel really good. We feel the same way about things. You know, again, this.

We’ve dated and romanced for probably 10 or 20 years, it’s not like, you know, we just saw this pretty girl across the street, fell in love, and got married in a month, you know? This is something that we really thought about and have thought about and talked about with each other for years and years, and the timing just seemed to be right right now, and we, and we did it. Thanks very much.

Catherine Mealor, Analyst, KBW3: The next question is from Dave Rochester with Cantor. Please go ahead.

Dave Rochester, Analyst, Cantor: Hey, good morning, guys.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Good morning.

Dave Rochester, Analyst, Cantor: I just wanted to go back to the capital discussion real quick. I noticed the shares are trading below the average price of the buybacks this past quarter. I was just curious if you see that buyback opportunity as occurring now. I know there are blackout periods related to the outstanding deals. If you could just talk about when you’d be actually able to buy back stock if you saw that opportunity in the near term, and if you had a 10b5-1 plan. Thanks.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Yeah. I don’t know what the 75 what plan is he talking about?

Charlotte Rasche, Executive Vice President and General Counsel, Prosperity Bancshares: The 10b5-1 plan.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: We don’t have one.

Charlotte Rasche, Executive Vice President and General Counsel, Prosperity Bancshares: Yeah, we don’t have a 10b5-1 plan.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Yeah. David, I would say on the others, you know, basically I’d probably stick to our statement that you’ve seen us buy in the past when it’s been opportunistic, and we’ll do that again.

Dave Rochester, Analyst, Cantor: Okay. Any sense for blackouts when those pop up, when those end, that kind of thing?

Charlotte Rasche, Executive Vice President and General Counsel, Prosperity Bancshares: Well, we’re in a blackout today for earnings.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Right

Charlotte Rasche, Executive Vice President and General Counsel, Prosperity Bancshares: We have formal earnings blackout and things, and there’s some blackouts around the merger transaction, of course, around shareholder votes and things like that when you start soliciting the Stellar shareholders.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: At this price.

Catherine Mealor, Analyst, KBW3: Before you do that.

Dave Rochester, Analyst, Cantor: Sorry, go ahead.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: I’d say at this price, and then when it’s available for us to buy back, we’ll do buybacks.

Charlotte Rasche, Executive Vice President and General Counsel, Prosperity Bancshares: Yeah.

Dave Rochester, Analyst, Cantor: Sounds good. I wanted to get your thoughts on the trajectory for NII and the margin through 2026, just given the 3 deals you got coming in. Just assuming you close Stellar June 30, can you just help us understand what you see as that path through the year? Thanks.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: If you look at Prosperity, I’m just gonna talk about Prosperity and with two smaller acquisition on projection. We definitely see the improvement in the margin for 2026 and beyond. It’s because the margin on the smaller banks were higher than ours as standalone, so that’s have accretion there. If you look at our balance sheet with, you know, repricing our bond portfolio, as I mentioned that we have a $1.9 billion cash flowing from that. We’ll be repricing that. Our yield on the bonds are 250 into pricing. I think we can get around 450 right now, so 200 basis points there. If you look at our fixed loans, that’s getting repriced as well.

Putting all together, our kind of projection for 2026 standalone showing about around 3.50% margin for 2026. If you add the Stellar Bank together, I think the margin on Stellar about more 4.2%. That will be very accretive too. Combined together, you can do the math. It will be looking very, very good for 2026.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: A minimum of 3.5.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Yeah, that-.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Minimum of three and a half.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: 3.5 without Stellar.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Yeah, without Stellar.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Yeah. That’s looking really good.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: That comes a long way. It, you know, it goes back to where two years ago somebody said, "Well, you know, the bank in your peer group, you know, you didn’t perform as good as your peer group over the last couple of years." Well, the truth of the matter is, we didn’t. I mean, our bank has never tried to call rates one way or another, and we bought in every market. In fact, we should be buying more, but I think we’re still scared from what happened last time. So for the most part, we said, you know, if every, we try to buy and have a 3.7, 3.8 year duration. We said two years ago, we got caught in that, and as this thing turns, we would turn it around.

We went from a 2.75 net interest margin to three and a half today. We did everything we said, and candidly, we have very strong tailwinds in back of us. I think that not only are you looking at 2026, 2027, without anything, we have some very strong tailwinds going at the same time.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Yeah. I want to add to that. I think we mentioned a year or 2 ago that we wanna reduce our borrowing levels. You know, we were almost at $3.9 billion borrowing 2 years ago, and we have conscious program that we’re gonna reduce it to level that we are right now. Now we believe that borrowing level is what we expected within $1.5 billion-$2 billion. Now we’re gonna be, you know, with growth in deposits and additional of the 2 banks, we’re gonna start growing our average earning assets, while past 2 years we were shrinking because we wanna shrink the borrowing.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: I think it was just a matter of the time that somebody could make an argument, and this email, the sharp email that I got this morning made that argument. I could make an argument that you could go back. Anybody can pick the year or time that they want to, but if you go back and for the last, since 2000 till today, and you compare us to the S&P 500 and you compare us to the Nasdaq Bank Index, our bank has returned 1,447% compared to the Nasdaq Bank Index of about, I’m thinking 181%. It’s compared to the S&P 500, 665%.

I think if you’re a long-term player, you need to jump in and buy this stock because I did the math for you a while ago, what this thing should trade for. I think it’s one of the greatest opportunities, and you will benefit if you’re a long-term investor right now.

Dave Rochester, Analyst, Cantor: All right, great. Appreciate all that color. Maybe just one last one on the cost save estimate. I know historically you guys have been pretty conservative or have outperformed your cost save expectations. I’m just wondering how you feel about about this level here that you’ve talked about and if there are any branch closures that you’ll have to take care of as a result of the higher concentration of branches in Houston. Thanks.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Regarding the cost save, we feel very comfortable with the 35% cost save that we printed. It’s combination of the combining two banks that have the same footprint, so of course there’ll be some consolidation of branches. Also, there’s, you know, as you know, the system conversion gonna help. We took deep dive, and we feel very comfortable with the cost saves.

Dave Rochester, Analyst, Cantor: Great. Thanks, guys.

Catherine Mealor, Analyst, KBW3: The next question is from Janet Lee with TD Cowen. Please go ahead.

Janet Lee, Analyst, TD Cowen: Good afternoon.

Catherine Mealor, Analyst, KBW0: Afternoon, Janet.

Janet Lee, Analyst, TD Cowen: Back to M&A. If I were to ask it in a different way, if I look at your pro forma CET1, it will be about 13.5, which is slightly above peers, but definitely more normalized than in the past. At least over the 5 years you’ve had CET1 running above peers. Given the size of the deal, which was more meaningful than the recent ones and the pro forma CET1 post the Stellar deal, does this change your appetite for M&A, whether it’s your appetite for M&A itself or the type of deals that you might be potentially looking at in the future?

Catherine Mealor, Analyst, KBW0: No. Even like I mentioned a while ago, when these things are combined, you’re gonna have over $600 million a year just in excess cash flow. We had excess capital that everybody was asking what we were gonna do this time. Again, it wasn’t a requirement that we pay 30% in cash down. We did to try to utilize our capital to get a better return on our average tangible capital. I think probably just in earnings over a couple of years, if you’ve done the ratios telling to see where, if we’re back up within a year or two, aren’t we?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Excuse me. On how fast we build our capital back?

Catherine Mealor, Analyst, KBW0: Right.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Yeah, we’ll be back in a couple of years at minimum.

Catherine Mealor, Analyst, KBW0: Minimum, a couple of years, we’ll be back to exactly where we’re at.

Janet Lee, Analyst, TD Cowen: Got it. That’s fair. For loan growth, it seems like the potential acquire portfolio runoffs from loans or deposits from the Stellar deal would not be material or meaningful. In terms of 2026, I believe you were hoping for that, you know, low single digits or low to mid single digits kind of growth on balance sheet. Is that the fair way to assume or I don’t wanna put words in your mouth, but how should we be thinking about the overall trajectory there?

Catherine Mealor, Analyst, KBW0: Yeah, I think that’s a good assumption. This is Kevin. Low single digits is good. As you know, Stellar’s been growing faster than that, and we don’t see any reason that that would change. I think American Bank has been growing faster than that as well. We talked about the quality of the Stellar portfolio. I’d say the same about the American Bank portfolio. We talked about Stellar maybe being cleaner than us. I think American Bank was cleaner than us.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Right. Right.

Catherine Mealor, Analyst, KBW0: In terms of the quality of the assets we’ve purchased here between American and Stellar, they are stellar.

Janet Lee, Analyst, TD Cowen: Great. Thank you.

Catherine Mealor, Analyst, KBW3: The next question is from Peter Winter with D.A. Davidson. Please go ahead.

Catherine Mealor, Analyst, KBW5: All right. Good morning. Thank you. Can you just talk a little bit, you mentioned the increase in non-performing assets. If you could give a little bit more detail. Last quarter, you highlighted the, like, $35 million SNC credit. Just wondering if that was part of the increase in non-performing assets and just how you’re thinking about credit quality going forward.

Catherine Mealor, Analyst, KBW0: Yeah. As we said, I would reiterate what we said last quarter, we said the portfolio is very clean. We had our eye on one particular asset which we had downgraded to substandard in the third quarter. It’s a $35 million Shared National Credit that we’re not the agent on. That credit was downgraded further in the fourth quarter to non-performing. It’s still substandard, but now non-accrual. As I said on the call in the third quarter, if that became more problematic, at this stage it has become more problematic, and we haven’t worked things out. Although it is, I will tell you, it is a well-known very large private equity firm who has a history of backing their deals. That doesn’t mean they’re backing this one, but they have a history of doing so.

It’s just that the resolution conversations have been challenging, or were challenging in the fourth quarter and continue to be challenging. We don’t see a need on this or the other credit we talked about last quarter, which is in the buy here, pay here space. We don’t see the need at this stage or if something went further wrong with these credits that we need to post a reserve as a result of it.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: I’d add that the other large-

Catherine Mealor, Analyst, KBW0: Post a provision, I should say. We have reserves up against both.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: I’d say the other large credit is a participation for one of the banks that we bought. Actually, we originated and sold the majority of it to another bank from the Lone Star deal. Basically it’s well secured with real estate. In fact, there should be excess equity in that. There shouldn’t be any loss in that.

Catherine Mealor, Analyst, KBW5: Got it. With the Stellar deal, what is the purchase accounting accretion going to the run rate? You gave it for the first quarter off the back, I am just wondering what it is after Stellar.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: The guidance that I provided on purchase accounting, fair value loan income, that’s for American Bank and Texas Partners Bank. If you look at just Stellar, I think on page 16, we disclose what the loan marks and AOCI mark. I think on the loan mark, we’re having about $31 million on loan marks at a pre-tax, and we have about $33 million net of tax and AOCI. For our modeling purpose, we use sum-of-years-digits calculation. If you look at for 2027, I think the mark accretion is about $31 million combined.

Catherine Mealor, Analyst, KBW5: Okay. Thanks for taking the questions.

Catherine Mealor, Analyst, KBW3: The next question is from Michael Rose with Raymond James. Please go ahead.

Catherine Mealor, Analyst, KBW2: Hey, good morning, guys. Thanks for taking my questions. Anything to do, you know, once the deal is either leading up to or once the deal is closed, just on the bond book. I know most of Legacy Prosperity’s book is HTM, but Stellar’s is AFS. Just wanted to see if there’s an opportunity for a potential restructuring that may be not included in the pro formas here. Thanks.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: You know, it’s not. We could. Everybody asks, "Why don’t you just do financial engineering, sell your deal, sell your portfolio?" If you can do the math on $10 billion, you make an extra 2%. You know, 2% a year is another $200 million income a year. You take your loss after tax, $600 million, and you get it back in 3 years. I just, again, feel like that’s just financial engineering. We could do it. It would make us look good, make us look like. Well, you do $200 million after tax and see what we have extra in income between us. I mean, we’d be making a whole lot of money. Again, I think that’s just financial engineering.

Again, we’ve always said that we’re not trying to call rates one way or play the market. We’re just trying to be in every market and buy with a 3.8 year duration. Sometimes it’ll be real good, and sometimes it’ll be low. I don’t see any change in that. Again, we will mark-to-market the.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Stellar

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: portfolio from Stellar for sure.

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: Mm-hmm.

Catherine Mealor, Analyst, KBW2: What would that do to the asset liability sensitivity?

Asylbek Osmonov, Chief Financial Officer, Prosperity Bancshares: I think they are a little bit of asset sensitive on that. I think what we’re gonna do, I mean, there will be some securities that we’re gonna sell and kind of buy back in a mortgage-backed security like we do. I think from the standpoint, it’s gonna be maybe the same as a slight asset sensitive.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: We’ll try to buy ahead so that it’s not so asset sensitive. We’ll try to get back to neutral if we can.

Catherine Mealor, Analyst, KBW2: understood. Maybe just finally, if there’s any Stellar guys in the room, I think Paul was in there. You know.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Bob.

Catherine Mealor, Analyst, KBW2: Just given how robust the NII forecasts are versus where consensus is. I guess the question is from your point of view, why sell now if the outlook is, or merge, or, you know, merge with Prosperity now if the outlook’s so good? Thanks.

Catherine Mealor, Analyst, KBW6: Well, I think it’s rare to get the opportunity to find somebody that kind of looks like you and thinks about the world the same way that you do. We’ve always concentrated on a real quality deposit base. I think that’s what Prosperity’s always done. We’re really sensitive around the way we fund ourselves to get a high quality deposit base, low cost of funds so that we can control that part of the deal. It’s hard to find people to partner with that look like that. I think the expanded balance sheet, the ability to continue to do kind of where the momentum started back in the third quarter into the fourth quarter, and we can see it in the first quarter, starting to have a real good momentum.

Because we look so similar and we do similar loans, similar types of deals, it’s not a heavy lift to understand that we could continue to do those kind of things. We think we’re gonna continue to drive that momentum. We feel good about what the future looks like over the, certainly over the next 12 months because I think we’re on a good path.

Catherine Mealor, Analyst, KBW2: Makes sense. Thanks for taking my questions, everyone.

Catherine Mealor, Analyst, KBW3: The next question is from Jared Shaw with Barclays Capital. Please go ahead.

Jared Shaw, Analyst, Barclays Capital: Hey, good afternoon. Maybe just, you know, going back to the original comment just about how, you know, your internal expectation for Stellar is better. When we look at their pipeline, David, do you feel like they’re able to get the pricing and terms that you said you’re not able to get in other markets? If so, would that cause you to reallocate more internal Prosperity resources to those markets to take advantage of that, you know, maybe disruption or relative difference between their markets and the rest of yours, what you’re doing in the state?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: I would like to say, to tell you that it would be great. We’d just use their loan team, they’ll make higher rate loans. What usually happens is banks that we join together, usually the return actually comes down. I mean, the net interest margin. You know, theirs, what is it, 4.2, you said? Ours is.

Catherine Mealor, Analyst, KBW6: Margin, yeah.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Ours is 3.5. Part of that margin is because they don’t have as big of a bond portfolio. Their margin is better because they have a better loan-to-deposit ratio too. Even having said that, even as we start merging together, it seems like their pricing from the banks that join us comes down a little bit. I just think the number of people though that Stellar has on the ground, and even with American Bank that had a loan production office here in the Houston market too. Together, we should really be able to inundate the market. This is such a big market. I mean, I don’t know that people realize how many people move in, what the GDP is of Texas. It’s just, it’s really phenomenal.

I think the opportunities are just unlimited, especially we get momentum, put our guys together, guys and girls. I think the momentum is really gonna be good for everybody. I think that we’ll. They maybe even had it better than us where a lot of our payment or pay to lenders is maybe more discretionary. We do look at the actual production. They were more on a formula-driven deal. I think that helps them too. We’ll probably look. You know, every bank that we join with, it looks like we take the. We try to do the best, we take the best from them and bring it to us.

I think they should be able to help us with some of this stuff too, and hopefully they won’t lower their rates that they’re charging, let’s say that.

Catherine Mealor, Analyst, KBW0: David, let me, if I can tag on to you on that.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Yeah. Yeah.

Catherine Mealor, Analyst, KBW0: I’ll be real simple. I think the margin differential is threefold, then Bob or somebody from Stellar could comment whether they agree with this or not. The obvious differences are we’ve got $10.5 billion in securities earning 2.17%.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Right.

Catherine Mealor, Analyst, KBW0: That’s a drag. The second big item on our balance sheet that’s a drag is $8.3 billion of single-family mortgages that were originated in times where rates were pretty low. That portfolio is a drag. Those are the two biggies. The one that doesn’t jump out at you all that we see, and we saw throughout due diligence is on the loan side of the bank, the basic commercial lending side of the bank. Forget single-family mortgages and some of the other stuff, just the basic commercial lending. They have a way more granular portfolio. The granularity of that portfolio basically means it’s smaller deals for the most part. They still do some big deals, but if it’s just on average, smaller deals for the most part tend to get higher pricing.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Right.

Catherine Mealor, Analyst, KBW0: It’s those three factors that really drive their margin relative to ours. I see ours improving as those low rate assets run off, and I don’t see theirs really having to come down all that much. Bob, would you-

Catherine Mealor, Analyst, KBW6: Yeah, I agree, Kevin. I mean, we do have a granular portfolio. I think there’s getting to be more and more balance to that over time. Pricing’s competitive. We’re in Houston, Texas, and pricing is competitive, so no, one’s not gonna be better pricing than the other. You guys are just as good as us at pricing loans. For the most part, it is granular, and we do get a little bit higher pricing on the smaller stuff. Yeah, I would agree with that.

Jared Shaw, Analyst, Barclays Capital: Okay, thanks. Then just as a follow-up.

Catherine Mealor, Analyst, KBW6: Which comes with cheap deposits. Yeah.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Right.

Catherine Mealor, Analyst, KBW6: Which is why your non-interest-bearing deposits are generally a bit higher than ours. Just a little additional inside baseball.

Jared Shaw, Analyst, Barclays Capital: Great. Thanks. I guess just as a follow-up, you know, what are some of the assumptions on customer retention, you know, as this will be, I guess, an additional name change over the past few years for Stellar? What do you think the risk is of retention?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: I’ll answer first, or Bob, you wanna go first? I mean.

Catherine Mealor, Analyst, KBW6: No, I was gonna say, I mean, I think we’re doing a good job of retaining our guys. I think that’s the big key, is to make sure that we keep our customer-facing folks out there, that our customers see every day and not changing that.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Yeah, I mean, we entered into about 15 non-compete agreements and about 70 letter retention agreements. I think the teams on board, it doesn’t mean you won’t lose somebody, but I think for the most part, you know, we’ll be able to retain the customers, and it’s not like another bank that’s coming out from another state that’s jumping in. They know who we are. We’ve advertised here. You know, it’s not somebody that they’re not familiar with. I think the retention is good here. I think again, they don’t have a lot of high yield time deposits or something that’s gonna run off like that. I mean, this is really a great combination, guys. It’s truly a marriage made in heaven.

Catherine Mealor, Analyst, KBW6: The other piece, David, I think is the credit cultures are very similar.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Right.

Catherine Mealor, Analyst, KBW6: We’ve always thought about the world the same way. I don’t think you see that drastic change that you do in some combinations where people say, "Oh gosh, you know, this is too conservative," or whatever they might think.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Well, you’re a lot like me. I mean, some of the guys, I mean, and even analysts, they wanna say, "Okay, you gotta have double-digit loan growth. Gotta do this. Gotta have 6%, 10% every year." Your deposits are growing 3%. What do you do when you run out of money? I think we have a lot of the same logics that, you know, we’re used to around the 80% loan-to-deposit ratio. Again, we bring in new deposits, we’ll make more, but we have a lot of liquidity. I think if there’s ever a run on our bank, for example, I think we have, like, $16 billion that we can draw in 1 minute. We have a lot of liquidity. Y’all have a lot of liquidity.

The combined earnings of these two banks, the liquidity of these two banks, they’re so similar. I think it’s a good deal.

Jared Shaw, Analyst, Barclays Capital: Thank you.

Catherine Mealor, Analyst, KBW3: The next question is from Jon Arfstrom with RBC Capital Markets. Please go ahead.

Jon Arfstrom, Analyst, RBC Capital Markets: Hey. Hello, everybody

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Hey, Jon.

Jon Arfstrom, Analyst, RBC Capital Markets: David, for you, just a couple, on the numbers. What’s your level of confidence in the $7.34 estimate for 2027? I don’t think you have any revenue synergies in there, so it seems like it’s just cost saves. You know, consensus $6.80s, you talk about the accretion. How confident are you in the $7.34?

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Cullen just handed me the $7.34. If he’s wrong, we’ll shoot him. We feel very confident, and I think we do have some triggers that I think that above beyond expenses. I mean, right now they don’t charge NSFs the charges. I’m not saying one way or another will go the other way. Their cost of money is a little bit higher than ours. We do have some other triggers. I feel very confident in the $7.34. You know, once we get everything combined, I think that’s a really real number. That’s why I can’t believe trading where we’re trading, if we’re gonna make $7.34. I mean, again, we should have a $95-$100 price target, really. Even you, Jon.

Jon Arfstrom, Analyst, RBC Capital Markets: I hear you.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Not that 75 stuff or 78.

Jon Arfstrom, Analyst, RBC Capital Markets: Well, okay, this begs the next question then. You kind of opened the door to it.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Uh-oh.

Jon Arfstrom, Analyst, RBC Capital Markets: Well, with your 15x acquisition multiple math.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Right

Jon Arfstrom, Analyst, RBC Capital Markets: ... that you shared earlier, you know, the question is, I’m not saying you should do it, but do the larger regionals call on you frequently? Is there a bid if you want it? Again, I’m not saying you should, but I’m just curious on that.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: You know, I was on the Federal Advisory Council in Washington, and every bank that you can imagine that size was on there. I mean, you had PNC, Truist, Regions. The answer to your question is they would all love us a lot. They would love us, and I would tell you that I wouldn’t even accept 15 times because I think we could even do better. Anybody that really wants to break into a market like Texas, you can’t do it. I mean, if you really wanna break into Texas and wanna be the largest bank in Texas, it’s gonna cost you something. That’s the difference in the price of cars. One’s a Ford Pinto and one’s a Jaguar. I mean, it’s just, they’re just a big difference.

Again, I’m not saying we are selling or not. I’m just telling you that we are truly undervalued in a takeout.

Jon Arfstrom, Analyst, RBC Capital Markets: Okay. Yeah, I think it adds a lot of franchise value despite today, so. Okay. Thank you very much.

David Zalman, Senior Chairman and Chief Executive Officer, Prosperity Bancshares: Thank you.

Catherine Mealor, Analyst, KBW3: This concludes our question and answer session. I would like to turn the conference back over to Charlotte Rasche for any closing remarks.

Charlotte Rasche, Executive Vice President and General Counsel, Prosperity Bancshares: Thank you. Thank you, ladies and gentlemen, for taking the time to participate in our call today. We appreciate your support of our company. We will continue to work on building shareholder value.

Catherine Mealor, Analyst, KBW3: Conference is now concluded. Thank you for attending today’s presentation. You may now disconnect.
