Stellar Bancorp's Shareholder-Friendly Strategy: A Case for Capital Efficiency and Value Creation

In the ever-evolving landscape of regional banking, Stellar Bancorp, Inc. (STEL) has emerged as a standout performer, leveraging its robust capital position and disciplined profitability to execute a strategic equity buyback program. The second quarter of 2025 has provided a compelling case study in how a well-capitalized institution can balance growth, risk management, and shareholder value creation. For investors, the question is no longer whether Stellar is executing well—it's whether the market is giving it enough credit for doing so.

A Buyback Anchored in Capital Strength

Stellar's recent repurchase of 791,000 shares at a weighted average price of $26.08 reflects a calculated approach to capital deployment. In a sector where many banks are cautious about returning capital, Stellar's actions signal confidence in its intrinsic value. The buyback is not a knee-jerk reaction to short-term volatility but a strategic move to reward shareholders when the stock trades at a discount to its tangible book value. With a tangible book value per share of $19.94 and a stock price of $31.53 as of July 2025, the company's P/B ratio of 1.58 suggests a moderate premium to its tangible assets—a reasonable multiple for a business with a 15.98% risk-based capital ratio and a history of disciplined lending.

The timing of the buyback is equally telling. Stellar's Q2 2025 results showed a 5.4% increase in net income year-over-year, with diluted earnings per share climbing to $0.51. Annualized returns on equity (ROE) and tangible equity stood at 6.62% and 12.16%, respectively—numbers that outpace most regional peers. These metrics underscore a company that is not only profitable but also generating returns that justify a premium valuation.

Profitability and Efficiency: The Twin Engines of Growth

Stellar's financial performance in Q2 2025 was marked by a delicate balance between growth and prudence. Net interest income of $98.3 million, though slightly down from Q1, was offset by a 5.2% increase in noninterest income, driven by Federal Reserve dividends and a leaner cost structure. The efficiency ratio improved to 61.87%, reflecting cost discipline amid rising interest rates. This is critical in an environment where net interest margins (NIMs) are under pressure: Stellar's NIM of 4.18%—though down marginally from 4.20% in Q1—remains resilient, supported by higher loan rates and a diversified deposit base.

What sets Stellar apart is its ability to grow deposits while maintaining low-cost liabilities. Total deposits rose by $110.9 million in Q2, driven by demand and money market accounts, even as certificates and time deposits declined. This shift to lower-cost funding reduces reliance on rate-sensitive liabilities, insulating the company from the volatility that has plagued some peers. Meanwhile, net charge-offs remained negligible at 0.01% of average loans, a testament to the strength of its credit culture and the economic resilience of its Texas-based markets.

Valuation: A Conservative Price for a Conservative Play

At a P/E ratio of 14.5, Stellar trades at a modest premium to its 8-year average of 14.67 and a discount to peers like National Bankshares (P/E 21.17). This multiple, combined with a P/B ratio of 1.01 (when compared to book value), suggests the stock is priced for stability rather than speculation. For investors seeking downside protection, Stellar's conservative valuation aligns with its conservative risk profile. The company's tangible book value of $19.94 per share—up from $19.69 in Q1—provides a floor for the stock price, while its ROE trajectory (up from 6.21% in Q1) hints at upward potential.

The buyback further enhances this value proposition. By retiring shares at a price below tangible book value, Stellar is effectively increasing earnings per share and tangible equity per share. For example, the $20.6 million spent on buybacks (791,000 shares × $26.08) could generate a 1.5% increase in tangible book value per share if the shares are repurchased at a discount. This is a rare win for both long-term capital preservation and short-term return enhancement.

The Case for Immediate Action

The market's muted reaction to Stellar's Q2 results and buyback program may present an opportunity for contrarian investors. While the stock has appreciated modestly over the past year, its valuation remains anchored to fundamentals rather than speculative hype. Consider the following:
1. Momentum: Stellar's management has signaled confidence in loan and deposit growth, particularly in Houston—a market primed for expansion thanks to the President's infrastructure spending bill.
2. Capital Position: A 15.98% risk-based capital ratio provides ample room for further buybacks or strategic acquisitions without compromising regulatory thresholds.
3. Valuation Tailwinds: A P/E ratio of 14.5 is historically justified for a company with Stellar's ROE and ROA, but it may rise as earnings momentum continues.

For investors, the calculus is clear: Stellar offers a rare combination of capital preservation, predictable earnings, and active shareholder returns. The buyback program, in particular, is a vote of confidence from management—a signal that the stock is undervalued and that capital is better deployed in repurchasing shares than in risky asset expansion.

Conclusion

Stellar Bancorp's Q2 2025 results and buyback strategy exemplify the power of disciplined capital allocation. In a market where many banks are retreating from shareholder returns, Stellar is doubling down on its strengths: profitability, efficiency, and a conservative balance sheet. For investors seeking a stable yet growth-oriented play in regional banking, the case for Stellar is both compelling and timely. The question is no longer whether Stellar can deliver—it's whether the market will recognize the value it's already created.
