Prosperity Bancshares News Roundup Here are the key news stories impacting Prosperity Bancshares this week:

Positive Sentiment: Zacks raised several earnings forecasts. The firm increased its FY2026 EPS estimate to $6.40 from $6.24, lifted FY2027 EPS to $7.22 from $7.16, and raised estimates for Q3 2026, Q4 2026, Q1 2027, Q2 2027, Q4 2027 and Q1 2028. These revisions signal improving expectations for PB’s medium-term profitability. Prosperity Bancshares analyst estimates Neutral Sentiment: Investors are comparing PB’s valuation with Cullen/Frost Bankers. A Zacks analysis examines which Southwest bank offers the better value opportunity. PB trades at a relatively modest valuation, with a reported P/E ratio near 12.6, but the article’s impact depends on its comparative conclusion and may be limited without a new company-specific catalyst. PB versus CFR value analysis Negative Sentiment: Some future-quarter estimates were reduced. Zacks lowered its Q3 2027 EPS forecast to $1.81 from $1.85 and trimmed its Q2 2028 estimate to $1.92 from $1.93. The cuts are small, but they indicate that the earnings outlook is not uniformly improving. Prosperity Bancshares revised estimates Negative Sentiment: Director Ned S. Holmes sold 1,100 shares for approximately $81,000 across two transactions at prices around $73.64–$73.67. He retained a substantial position, so the sales are not necessarily a strong bearish signal, but insider selling can weigh modestly on sentiment.

Prosperity Bancshares continues to deliver robust earnings growth, driven by an expanding net interest margin and M&A activity. Last quarter, PB's net interest margin rose 29 basis points to 3.47%. While already-low funding costs will be hard to improve, fixed-asset repricing can fuel further margin expansion from here. Strong capital levels are enabling ongoing M&A, with recent acquisitions fueling double-digit volume growth last quarter.

Investors interested in Banks - Southwest stocks are likely familiar with Prosperity Bancshares (PB - Free Report) and Cullen/Frost Bankers (CFR - Free Report) . But which of these two stocks offers value investors a better bang for their buck right now? We'll need to take a closer look.

We have found that the best way to discover great value opportunities is to pair a strong Zacks Rank with a great grade in the Value category of our Style Scores system. The Zacks Rank favors stocks with strong earnings estimate revision trends, and our Style Scores highlight companies with specific traits.

Currently, Prosperity Bancshares has a Zacks Rank of #2 (Buy), while Cullen/Frost Bankers has a Zacks Rank of #3 (Hold). This means that PB's earnings estimate revision activity has been more impressive, so investors should feel comfortable with its improving analyst outlook. But this is just one factor that value investors are interested in.

Value investors also tend to look at a number of traditional, tried-and-true figures to help them find stocks that they believe are undervalued at their current share price levels.

Our Value category grades stocks based on a number of key metrics, including the tried-and-true P/E ratio, the P/S ratio, earnings yield, and cash flow per share, as well as a variety of other fundamentals that value investors frequently use.

PB currently has a forward P/E ratio of 11.62, while CFR has a forward P/E of 15.60. We also note that PB has a PEG ratio of 0.82. This metric is used similarly to the famous P/E ratio, but the PEG ratio also takes into account the stock's expected earnings growth rate. CFR currently has a PEG ratio of 2.60.

Another notable valuation metric for PB is its P/B ratio of 0.91. The P/B ratio is used to compare a stock's market value with its book value, which is defined as total assets minus total liabilities. For comparison, CFR has a P/B of 2.34.

These metrics, and several others, help PB earn a Value grade of B, while CFR has been given a Value grade of C.

PB is currently sporting an improving earnings outlook, which makes it stick out in our Zacks Rank model. And, based on the above valuation metrics, we feel that PB is likely the superior value option right now.

Prosperity Bancshares delivered Q2 2026 earnings and revenue beats, supported by recent acquisitions and strong Texas/Oklahoma market exposure. PB's premium valuation is justified by robust core metrics: low-cost deposits, above-average dividend yield (3.21%), and strong efficiency and asset quality ratios. Recent M&A activity, including the Stellar Bancorp acquisition, positions PB for continued growth but introduces integration and tangible book value dilution risks.

Key Takeaways Prosperity Bancshares beat Q2 earnings estimates as revenues rose 25.9% year over year.PB benefited from higher net interest income, merger contributions, and a Visa Class B-2 stock gain.Prosperity Bancshares completed the Stellar Bancorp acquisition and continued integration efforts. Prosperity Bancshares, Inc.’s (PB - Free Report)  second-quarter 2026 adjusted earnings of $1.62 per share surpassed the Zacks Consensus Estimate of $1.54. The bottom line increased 14.1% from the year-ago quarter.

Subsequent to the reported quarter, Prosperity Bancshares completed the acquisition of Stellar Bancorp and its subsidiary, Steller Bank, on July 1, 2026. The company also continued to integrate the acquisitions of American Bank Holding Corporation and Southwest Bancshares, which were completed earlier this year.

Results benefited from higher net interest income (NII) and non-interest income alongside no provision for credit losses. Higher loans and deposit balances were another positive. However, increased operating expenses partly offset these tailwinds.

The results excluded the net gain from the Visa Class B-2 stock exchange, investment securities sales, and merger-related expenses. Including non-recurring items, net income available to common shareholders was $168.6 million, or $1.67 per share, compared with $135.2 million or $1.42 per share in the year-ago quarter. Our estimate for net income available to common shareholders was $111.5 million.

PB’s Revenues Improve, Expenses RiseTotal revenues were $391.3 million, up 25.9% year over year. The top line surpassed the Zacks Consensus Estimate of $376.1 million.

NII rose 23.5% year over year to $330.6 million. Also, the net interest margin (NIM), on a tax-equivalent basis, expanded 29 basis points to 3.47%. Our estimates for NII and NIM were pegged at $326.2 million and 3.50%, respectively.

Non-interest income totaled $60.7 million, up 41.2% year over year. The increase was primarily driven by the American and Southwest mergers and an $8.2 million gain on the Visa Class B-2 stock exchange, net of investment securities sales. Our estimate for the metric was $46.7 million and did not include Visa share sale gains.

Non-interest expenses were $176.2 million, up 27.1% year over year. The increase was primarily due to higher salaries and benefits and additional expenses related to the American and Southwest operations. Our estimate for non-interest expenses was $228.1 million.

The efficiency ratio improved to 45.99% from 44.80% in the prior-year quarter.

PB’s Balance Sheet ExpandsAs of June 30, 2026, total assets were $43.87 billion, up 14.2% year over year, primarily due to the acquisitions of American Bank Holding Corporation and Southwest Bancshares.

Total loans were $25.03 billion, up 12.8% year over year. Deposits increased 18.7% year over year to $32.6 billion, mainly reflecting the impact of the two acquisitions. Our estimates for total loans and total deposits were $25.3 billion and $33.02 billion, respectively.

PB’s Capital Ratios Decline, Profitability Ratios ImproveAs of June 30, 2026, the common equity tier 1 ratio was 15.94%, down from 17.10% in the year-ago quarter. The total risk-based capital ratio declined to 17.38% from 18.35% in the prior-year quarter. The equity-to-assets ratio was 18.93%, down from 19.78% as of June 30, 2025.

At the end of the second quarter, return on average assets was 1.55%, up from 1.41% in the prior-year quarter. The return on average common equity was 8.14%, up from 7.13% in the prior-year quarter.

PB’s Credit Quality: A Mixed BagAs of June 30, 2026, non-performing assets were $130.6 million, up 18.2% from the year-ago period. Net charge-offs were $2.2 million, down from $3 million in the same quarter of 2025, primarily reflecting the resolution of purchased credit deteriorated (PCD) loans.

The company reported no provision for credit losses during the reported quarter, unchanged from the year-ago period. The ratio of allowance for credit losses on loans was $1.53% of the total loans, down from 1.56% a year earlier.

Prosperity Bancshares’s Share Repurchase UpdateIn the reported quarter, the company repurchased 0.2 million shares at an average weighted price of $68.34 per share for a total of $13.7 million under its ongoing 2026 stock buyback program.

Our Take on PBProsperity Bancshares’ inorganic expansion strategy is expected to support revenue growth and strengthen its Texas franchise. The company’s favorable deposit mix and solid NIM remain key positives. However, rising expenses may hurt the bottom line to some extent.

Currently, Prosperity Bancshares carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

BOKF’s results benefited from higher NII and total fees and commissions. An increase in loans was another positive. However, the rise in operating expenses was a major undermining factor.

Bank OZK’s (OZK - Free Report) second-quarter 2026 earnings per share of $1.49 surpassed the Zacks Consensus Estimate of $1.46. However, the bottom line declined 5.7% year over year from $1.58.

For the three months ended June 30, 2026, net income was $168.6 million(2) or $1.67 per diluted common share compared with $135.2 million(3) or $1.42 per diluted common share for the same period in 2025. Net income and net income per diluted common share for the second quarter of 2026 were primarily impacted by an increase in net interest income and a gain on Visa Class B-2 stock exchange net of investment securities sales of $8.2 million, partially offset by an increase in noninterest expenses related to the American and Southwest operations and an increase in provision for income taxes. On a linked quarter basis, net income was $168.6 million(2) or $1.67 per diluted common share for the three months ended June 30, 2026, compared with $116.3 million(4) or $1.16 for the three months ended March 31, 2026. The change was primarily due to an increase in net interest income, lower merger related expenses and a gain on Visa Class B-2 stock exchange net of investment securities sales of $8.2 million. Annualized returns on average assets, average common equity and average tangible common equity for the three months ended June 30, 2026, were 1.55%, 8.14% and 15.48%(1), respectively.

Excluding the gain on Visa Class B-2 stock exchange net of investment securities sales, net of tax, and merger related expenses, net of tax, net income was $162.7(1)million and earnings per diluted common share was $1.62(1) for the three months ended June 30, 2026, and annualized returns on average assets, average common equity and average tangible common equity were 1.50%(1), 7.85%(1) and 14.93%(1), respectively. Prosperity's efficiency ratio (excluding net gains and losses on the sale, write-down or write-up of assets and securities) was 45.99%(1) for the three months ended June 30, 2026, and excluding the merger related expenses, the efficiency ratio was 45.79%(1).

Net interest income before provision for credit losses was $330.6 million for the three months ended June 30, 2026, compared with $267.7 million for the same period in 2025, an increase of $62.8 million or 23.5%. The net interest margin on a tax equivalent basis was 3.47% for the three months ended June 30, 2026, compared with 3.18% for the same period in 2025. The changes to both measures were primarily due to the repricing of assets, a decrease in the average balance and average rate on other borrowings and the impact of the American Merger and the Southwest Merger. Net interest income before provision for credit losses increased $9.4 million or 2.9% to $330.6 million for the three months ended June 30, 2026, compared with $321.2 million for the three months ended March 31, 2026. The net interest margin on a tax equivalent basis was 3.47% for the three months ended June 30, 2026, compared with 3.51% for the three months ended March 31, 2026. The decrease was primarily due to one-time loan interest income from a nonaccrual loan in the first quarter of 2026.

Noninterest income was $60.7 million for the three months ended June 30, 2026, compared with $43.0 million for the same period in 2025, an increase of $17.7 million or 41.2%. The change was primarily due to the American Merger and the Southwest Merger and a gain on Visa Class B-2 stock exchange net of investment securities sales of $8.2 million. Noninterest income was $60.7 million for the three months ended June 30, 2026, compared with $46.5 million for the three months ended March 31, 2026, an increase of $14.2 million or 30.6%. The change was primarily due to a gain on Visa Class B-2 stock exchange net of investment securities sales of $8.2 million and an increase in other noninterest income.

Noninterest expense was $176.2 million for the three months ended June 30, 2026, compared with $138.6 million for the same period in 2025, an increase of $37.6 million. The change was primarily due to an increase in salaries and benefits and an increase in additional expenses related to three months of American and Southwest operations. Noninterest expense was $176.2 million for the three months ended June 30, 2026, compared with $217.3 million for the three months ended March 31, 2026, a decrease of $41.1 million, which was primarily due to lower merger related expenses.

Non-GAAP Financial Measures

Prosperity's management uses certain non-GAAP financial measures to evaluate its performance. Specifically, for internal planning and forecasting purposes, Prosperity reviews each of diluted earnings per share, return on average assets, return on average common equity, and return on average tangible common equity, in each case excluding merger related expenses, net of tax, FDIC special assessment, net of tax and net gain on the sale or write-up of securities; return on average tangible common equity; tangible book value per share; the tangible equity to tangible assets ratio; allowance for credit losses to total loans excluding Warehouse Purchase Program loans; the efficiency ratio, excluding net gains and losses on the sale and securities, write-down or write-up of assets; and the efficiency ratio, excluding net gains and losses on the sale, write-down or write-up of assets and securities, merger related expenses, and FDIC special assessment. Prosperity believes these non-GAAP financial measures provide information useful to investors in understanding Prosperity's financial results and their presentation, together with the accompanying reconciliations, provide a more complete understanding of factors and trends affecting Prosperity's business and allow investors to view performance in a manner similar to management, the entire financial services sector, bank stock analysts and bank regulators. Further, Prosperity believes that these non-GAAP financial measures provide useful information by excluding certain items that may not be indicative of its core operating earnings and business outlook. These non-GAAP financial measures should not be considered a substitute for, nor of greater importance than, GAAP basis financial measures and results; Prosperity strongly encourages investors to review its consolidated financial statements in their entirety and not to rely on any single financial measure. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names. Please refer to the "Notes to Selected Financial Data" at the end of this Earnings Release for a reconciliation of these non-GAAP financial measures to the nearest respective GAAP financial measures.

Notes to Selected Financial Data (Unaudited)
(Dollars and share amounts in thousands, except per share data)

NOTES TO SELECTED FINANCIAL DATA

Prosperity's management uses certain non-GAAP (generally accepted accounting principles) financial measures to evaluate its performance. Specifically, for internal planning and forecasting purposes, Prosperity reviews each of diluted earnings per share, return on average assets, return on average common equity, and return on average tangible common equity, in each case excluding merger related expenses, net of tax, FDIC special assessment, net of tax, and net gain on sale or write-up of securities, net of tax; return on average tangible common equity; tangible book value per share; the tangible equity to tangible assets ratio; allowance for credit losses to total loans excluding Warehouse Purchase Program loans; the efficiency ratio, excluding net gains and losses on the sale, write-down or write-up of assets and securities; and the efficiency ratio, excluding net gains and losses on the sale, write-down or write-up of assets and securities, merger related expenses and FDIC special assessment. In addition, due to the application of purchase accounting, Prosperity uses certain non-GAAP financial measures and ratios that exclude the impact of these items to evaluate its allowance for credit losses to total loans (excluding Warehouse Purchase Program loans). Prosperity has included information below relating to these non-GAAP financial measures for the applicable periods presented.
