How much has the company actually repurchased so far?

Prosperity repurchased 1.04 million shares during the first six months of 2026 at an average price of $68.19 per share, totaling $70.8 million. This represents approximately 21% of the authorized share count.

Why is the buyback relatively modest given the company's size?

Prosperity completed three acquisitions during the first half of 2026—American Bank Holding (January), Southwest Bancshares (February), and Stellar Bancorp (July)—which collectively added approximately $10.4 billion in assets. The company appears to be prioritizing integration of these acquisitions while selectively deploying excess capital through share repurchases.

How does a bank's buyback program differ from a typical corporate repurchase?

Bank buyback programs are subject to regulatory oversight and capital requirements. Prosperity's discretionary repurchase approach allows management flexibility to suspend or accelerate repurchases based on capital levels, loan demand, deposits, and integration needs from acquisitions.

What does the average repurchase price tell us?

The average price of $68.19 per share in H1 2026 was close to the period-end closing price of $73.03 as of June 30, 2026, suggesting the company repurchased at prices generally near the period-end market value, without significant market timing advantage or disadvantage.

When can shareholders expect the repurchase program to conclude?

The repurchase program expires January 26, 2027. With 3.83 million shares of the 4.87 million authorized remaining, Prosperity has approximately six months from the filing date to execute additional repurchases at management's discretion.

What this means

Prosperity Bancshares has returned approximately $70.8 million to shareholders through buybacks in the first half of 2026, reducing share count by roughly 1.04 million shares (about 1.1% of the average share base). This execution demonstrates moderate capital deployment despite aggressive acquisition activity. With 4.87 million shares authorized under the one-year program and only 1.04 million repurchased as of June 30, approximately 3.83 million shares remain available for repurchase through January 26, 2027. The buyback activity is modest relative to the company's $43.9 billion asset base and reflects prudent capital management during integration of three significant acquisitions that collectively added over $5.4 billion in assets in the first half of 2026.
