Prosperity Bancshares Inc. Shareholders: Ownership Structure, Brands, and Acquisition History
Last updated: Oct-2026Ownership Structure
Ownership Analysis
Roughly 23.5% of Prosperity belongs to four institutions, and we think who is missing matters more than who is there. The four are BlackRock at 8.04%, AQR at 5.25%, and two Vanguard units at 5.17% and 5.04%. They were measured before the Stellar merger, so we estimate each has been diluted by about 16%, because 19.4 million new shares joined a base of about 100.8 million. No holder is large enough to demand a board seat or force a sale. Index funds in particular rarely vote against management, so we expect little friction on strategy.That leaves David Zalman and the board in charge. We put Zalman's direct stake at 795,651 shares, worth about $53.6 million at $67.38, or 0.66% of the company. An aggregator estimates all insiders at 3.55%, which we treat as unconfirmed. Either way, management owns a much smaller share than a founder family would, so we do not class Prosperity as founder controlled.Stellar's directors form a small new bloc. They collectively owned 8.7% of Stellar's roughly 50.9 million shares, or about 4.4 million. At 0.3803 Prosperity shares each, that is about 1.7 million Prosperity shares, or 1.4% of the 120.2 million outstanding. Two of them now sit on the board.We read the thin ownership as an advantage for deal making. In 2026 the company issued about 27.9 million shares across three acquisitions without needing any large owner's consent. Our worry is the reverse: when no owner is large, nobody has the stake or the motive to question a $2 billion purchase. Our view is that shareholders are relying mainly on continuity of leadership, and we would watch the next proxy statement for any word on succession.

Shareholder Analysis
Why would a company that just issued 27.9 million shares keep buying stock back? We think the answer is signaling, since the arithmetic is small. Prosperity repurchased 2.34 million shares for $157.1 million in 2025, at an average $67.04. In the first half of 2026 it bought 1.04 million at $68.19, about $70.9 million. That is only 3.7% of the shares issued for the 2026 deals, so we do not see buybacks as undoing the dilution.Shareholders are paid mainly by dividends. At $0.60 a quarter, or $2.40 a year, the yield is 3.56%, and against 2025 earnings of $5.72 a share the payout is about 42%. Across 120.18 million shares the dividend costs about $288 million a year. Set against the second quarter's net income of $168.6 million, or $674 million annualized, that is a payout of 43%, which we consider comfortable. The shares now trade at $67.38, a little below the $68.19 average the company paid in 2026, so recent buybacks are slightly under water.The holders themselves tell us what to expect. BlackRock and the two Vanguard units are index investors, who buy whenever the stock is in an index. AQR, at 5.25%, builds portfolios using computer rules that favor cheap, profitable shares. That mix supports the stock when valuation is low but offers no one to push for change.We would watch the 4.87 million share authorization. At $67.38 it could retire about 4% of the shares, but the company must choose between buying stock and digesting Stellar. Our expectation is that it keeps buying modestly, with the dividend as its main commitment to owners. If the shares fall well below $60, we would expect faster buying, and we would welcome it.

Portfolio Analysis
Prosperity is really one bank, so we judge its mix by money source and place. Net interest income of $1.081 billion was 86.5% of 2025 revenue of about $1.249 billion, and fees of $168.3 million supplied the other 13.5%. We do not mind the small fee share. The company makes money from cheap deposits, not from selling products, and that makes results easy to predict.The deposit base is the real asset. At June 30, 2026, deposits were $32.600 billion against loans of $25.028 billion, a loan to deposit ratio of 76.8%. The company's own deal materials put the combined ratio at 78.9% and say 34% of deposits pay no interest. Free funding like that helps explain why the net interest margin, the gap between what a bank earns on loans and pays on deposits, rose to 3.47% in the second quarter. By our subtraction of the 29 basis point gain, a year earlier it was 3.18%.Place matters too. Stellar adds 52 offices in Houston, Beaumont, East Texas and Dallas, and the company calls itself the largest deposit franchise headquartered in Houston. Stellar earned a margin of 4.21% in the fourth quarter of 2025, well above Prosperity's 3.22% for the full year, which is part of what the company is buying. Oklahoma branches add a second state. Total locations are now 363, up from 301 at the end of 2025.Our concern is geography. The franchise is concentrated in Texas, so a real estate or oil downturn there would reach most branches at once. Nonperforming assets were 0.34% of average earning assets in the second quarter, which we consider low. Our conclusion is that the franchise is strong and plain, and we would watch credit quality as the larger loan book matures.
Market Share & Competitors
| Company | Market Share | Revenue | Key Strength |
|---|---|---|---|
| Prosperity Bancshares ★ | N/A | $1.25B FY2025 | Low cost deposits and tight expense control |
| Cullen/Frost Bankers | N/A | $2.24B FY2025 | Largest Texas bank by assets with strong commercial franchise |
| Hancock Whitney | N/A | $1.53B FY2025 | Gulf South commercial bank with Texas presence |
| BOK Financial | N/A | $2.17B FY2025 | Oklahoma based bank with large fee businesses |
| Texas Capital Bancshares | N/A | $1.26B FY2025 | Commercial and investment banking focus in Dallas |
Competitive Analysis
We compare Prosperity to Cullen/Frost, Hancock Whitney, BOK Financial and Texas Capital. Comerica and Cadence are no longer independent: Fifth Third completed its purchase of Comerica in early February 2026, and Huntington has completed its merger with Cadence, so we left both out. Revenue here means net interest income plus noninterest income for 2025.Cullen/Frost earned $2.235 billion, BOK $2.17 billion, Hancock $1.53 billion, Texas Capital $1.26 billion and Prosperity $1.25 billion. Prosperity is smallest on that measure, yet we find it highly profitable for its size. Its net income of $542.8 million is 1.41% of its $38.463 billion of assets. Cullen/Frost earned $648.6 million on $53.041 billion, or 1.22%, and Hancock $486.1 million on $35.5 billion, or 1.37%.We explain the gap with costs and funding. Prosperity projects a combined efficiency ratio, which is expenses as a share of revenue, of about 44% in 2027. Hancock reported 54.93% for 2025 and Texas Capital 61.2%, so on these figures Prosperity spends noticeably less to earn a dollar. Texas Capital, with net income of $313.0 million and a 1.04% return on assets, is still rebuilding toward that level.After Stellar, Prosperity's assets of roughly $54 billion are level with Cullen/Frost's $53.0 billion, so the size gap that once kept it a rung below has closed. The company calls itself the second largest Texas headquartered bank. Our conclusion is that Prosperity now competes for the same large commercial clients, and we would watch whether it keeps its profit edge as it moves up. Frost's new $300 million buyback and $1.00 quarterly dividend show it intends to hold its position. BOK, with Oklahoma roots and large fee businesses, overlaps with Prosperity's Oklahoma branches, though we see it as a smaller threat in Texas.
Acquisitions
| Company Acquired | Deal Value | Year | Description |
|---|---|---|---|
| Stellar Bancorp Inc | $2.00B | 2026 | Houston based bank with 52 offices and $10.8B of assets at announcement |
| LegacyTexas Financial Group Inc | $2.13B | 2019 | Plano based bank with 42 Dallas Fort Worth locations |
| American State Financial Corporation | $536.8M | 2012 | Lubbock based bank with 37 West Texas offices |
| First Bancshares of Texas Inc | $341.6M | 2023 | Parent of FirstCapital Bank of Texas with 16 locations |
| American Bank Holding Corporation | $321.5M | 2026 | Texas and Oklahoma bank with 18 offices and $2.5B of assets |
| Southwest Bancshares Inc | $268.9M | 2026 | San Antonio parent of Texas Partners Bank with 11 offices |
| Lone Star State Bancshares Inc | $228.7M | 2024 | Lubbock parent of Lone Star State Bank of West Texas with 5 offices |
Acquisitions Analysis
Seven priced deals add up to $5.83 billion by our sum. Stellar cost $2.00 billion and LegacyTexas $2.128 billion. American State was $536.8 million, First Bancshares of Texas $341.6 million and American Bank $321.5 million. Southwest Bancshares was $268.9 million and Lone Star State $228.7 million. The three 2026 deals alone come to $2.59 billion, 44% of that total, and they lifted assets from $38.463 billion at the end of 2025 to roughly $54 billion.Is Prosperity overpaying? We think the price is high but defensible. The company's presentation shows Stellar at 1.81 times tangible book value and 19.7 times 2025 earnings. Prosperity's own shares trade at about 11.8 times its 2025 earnings per share of $5.72. Paying a higher multiple than your own only works with cost cuts. Prosperity targets savings of 35% of Stellar's noninterest expense, or $113 million to $126 million across 2026 and 2027, and with those savings it puts the price at 10.7 times 2026 earnings.The cost to current owners is real. Tangible book value per share falls 7.8%, and the company expects about 4.5 years to earn it back. It also projects 9.2% earnings accretion in 2027, which we think is achievable given how quickly earlier deals closed: American Bank and Southwest both finished within six months of signing. Goodwill from the three 2026 deals was $185.0 million, $134.1 million and $733.7 million, about $1.05 billion in all.Our view is that the plan works if the savings arrive on time, since without them the premium over Prosperity's own multiple has no support. We would watch noninterest expense each quarter, and the $2.17 billion of Federal Home Loan Bank of Dallas borrowings taken over from Stellar, because their cost affects the margin we expect.
Acquisition Timeline
Merger & Spin-off History
Merger & Spin-off Analysis
What did Stellar holders actually receive, and how did the value move? At the January 28, 2026 announcement, each Stellar share was worth $39.08, built from 0.3803 Prosperity shares at $72.90 plus $11.36 in cash, a total of about $2.002 billion. By closing on July 1, 19.4 million Prosperity shares valued at $73.03 each, or $1.415 billion, plus $578.7 million in cash made $1.993 billion. At the $67.38 price on October 2, we calculate the same offer at $36.98 per Stellar share. The stock part of the price has therefore fallen about 7.6% since signing.The deal took just over five months to close, which we consider fast for a $2 billion bank merger. About 70% of the price was stock and 30% cash, so Stellar holders kept a stake in the result. They now own roughly 16% of the combined company, matching the 84 to 16 split in the company's presentation.Prosperity gave governance seats as well as shares. Robert Franklin became Vice Chairman, with a three year employment agreement at a $1,120,187 base salary, a $3 million signing bonus and 25,000 restricted shares. He and Joseph Swinbank joined a 16 member board, while Ramon Vitulli became Houston Area Chairman. We think this retention of Stellar's leaders shows real concern about keeping Houston customers.Our conclusion is that the structure was sound: the cash portion limited dilution while the stock portion kept capital intact. Our one worry is the share price, which has slipped since signing, because Stellar holders who wanted to sell have seen a smaller payout than the headline suggested. That does not change the price Prosperity paid for the bank itself. We would watch the March 2027 branch conversion, because that is when customers decide whether to stay.
Ownership History
Ownership History Analysis
A one branch bank formed in Edna, Texas, in 1983 now has about $54 billion of assets and a market value of $8.10 billion. We trace that growth through acquisitions, and through the share count: 95.26 million shares in February 2025, 101.58 million a year later and 120.18 million today. That is a 26% rise in about 20 months, by our math, and almost all of it came from stock used to pay for banks.The same history shows a thin owner stake. David Zalman, who has led the company for decades, holds 795,651 shares directly, about 0.66% today. The 2025 proxy statement describes him as the son-in-law of Perry Mueller Jr., which suggests family ties run deeper than the share count shows. We cannot measure those ties from public data, so we do not count them.Operating results have kept pace with the growth. Net income rose 13.2% in 2025 to $542.8 million, or $5.72 a share, and the second quarter of 2026 earned $1.67 a share. We think that record, more than any ownership detail, is why shareholders have let the company issue shares so freely.We therefore view Prosperity as professionally managed, though still shaped by its long time leader. Zalman is Senior Chairman and Chief Executive Officer and Kevin Hanigan is President. Stock ownership has also moved to funds: BlackRock, AQR and two Vanguard units together hold about 23.5% on pre-merger counts. Our conclusion is that Prosperity has swapped founder control for dispersed, passive ownership, and that its main risk is succession rather than any shareholder fight. We would watch the next proxy statement for any change in titles, and for the first full year of results with Stellar included.
Ownership Explained
Prosperity Bancshares Inc. is a publicly traded financial holding company headquartered in Houston, Texas. Its shares trade on the New York Stock Exchange under the symbol PB. In early October 2026 there were 120,176,771 shares outstanding, and at $67.38 a share the market value was about $8.10 billion. No person, family or parent company controls it.The largest holders are index and quantitative asset managers. MarketScreener lists BlackRock at 8.04%, AQR Capital Management at 5.25% and Vanguard Portfolio Management at 5.17%. A separate Vanguard unit, Vanguard Capital Management, reported 5,115,938 shares, or 5.04%, in a Schedule 13G filing for March 31, 2026. These percentages were measured on share counts from before the Stellar merger, so each is now somewhat smaller.David Zalman is Senior Chairman and Chief Executive Officer. GuruFocus shows him holding 795,651 shares directly, about 0.66% of the current total. The company traces its start to 1983, when it was formed in Edna, Texas, to buy a former Allied Bank branch. The 2025 proxy statement describes Zalman as the son-in-law of Perry Mueller Jr. Cullen Zalman serves as Executive Vice President for banking and corporate activities.Prosperity completed its merger with Stellar Bancorp Inc. on July 1, 2026, and remains the surviving public company. Stellar shareholders received 0.3803 Prosperity shares plus $11.36 in cash for each Stellar share. That meant about 19.4 million new Prosperity shares and $578.7 million in cash, for a total value of $1.993 billion at the June 30 closing price of $73.03. Former Stellar holders now own about 16% of the combined company.Robert R. Franklin Jr., Stellar's chief executive, became Vice Chairman, and he and Joseph B. Swinbank joined an expanded 16 member board. The combined bank operates 363 banking locations in Texas and Oklahoma and holds roughly $54 billion of assets. The share count was 95,262,717 on the 2025 proxy record date and 101,581,522 on February 23, 2026.
For customers, the Stellar merger changes the name on the door but not the type of owner. Prosperity is a widely held public company, so no parent or founder family decides how branches or products are run. Stellar customers in Houston, Beaumont, East Texas and Dallas will see Stellar branches converted to Prosperity Bank branding in March 2027. Until then, the company says operations continue as they are.For employees, the merger brings overlap. Prosperity has targeted cost savings equal to 35% of Stellar's noninterest expense, which it puts at $113 million to $126 million across 2026 and 2027, with about $100 million of one time costs. That points to job cuts and branch consolidation where the two networks sit close together. Prosperity employed 3,941 full time equivalent people at the end of 2025, before the three 2026 deals added staff.For investors, three things follow from the ownership structure. First, existing holders were diluted: 19.4 million new shares went to Stellar holders, who now own about 16%. Second, the company pays a quarterly dividend of $0.60, or $2.40 a year, a yield of 3.56% at $67.38. Third, the board has authorized repurchases of up to 4.87 million shares for 2026, and 1.04 million shares had been bought by June 30 at an average $68.19.Because index and quantitative funds hold the largest blocks, the stock can move with fund flows as well as with earnings. Insiders own little: Zalman's direct stake is about 0.66%. Fourteen brokerages rate the stock Hold on average, with a mean price target of $78.36, about 16% above the October 2 close. The next earnings report is due October 28, 2026, and it will be the first to include Stellar for a full quarter.
