1st Source Corporation (SRCE) Balance Sheet

The balance sheet is clearly in expansion mode, with total assets growing from $8.7B in 2024Q1 to $9.3B in 2026Q2, a 6.9% cumulative increase. The growth is organic, fueled by a strong deposit franchise, as evidenced by deposit growth outpacing loan growth (3.28% vs 1.71% quarter-over-quarter). This suggests the bank is successfully gathering low-cost funding to support its specialty lending, without resorting to M&A or wholesale funding.

The deposit franchise remains the cornerstone of SRCE's funding strategy, with the bank's Michiana presence providing a stable, low-cost base. The fact that deposit growth is accelerating even in a high-rate environment suggests that the bank has not had to aggressively raise deposit rates, which supports margin stability. However, investors should monitor the cost of these incremental deposits, as sustained rate pressure could eventually force the bank to pay up, squeezing net interest margin.

The sharp reduction in provision expense in 2026Q2 is notable, but it follows a quarter of elevated provisioning, suggesting that credit costs are lumpy rather than trending upward. The bank's niche focus on transportation and equipment finance appears to be performing well, with no signs of deterioration in the secondary market for used aircraft or trucks. However, the volatility in provisions warrants close monitoring, as any softening in collateral values could require higher reserves.

The bank's capital position is steadily building, with equity growing to $1.3B, supported by robust earnings retention. The equity-to-assets ratio, while low in absolute terms due to the bank's asset mix, is trending upward, indicating a strengthening capital base. This provides ample buffer for organic growth and potential capital returns, though management has historically prioritized credit quality over aggressive deployment.

The dramatic increase in cash holdings suggests that SRCE is accumulating liquidity, likely as a result of strong deposit inflows. This positions the bank well to fund loan growth or navigate potential market disruptions. The investment securities portfolio remains substantial at $8.5B, providing additional liquidity, though the bank's reliance on core deposits rather than wholesale funding is a positive indicator of stability.

The stability of the net interest margin is a key positive, but it is not guaranteed. The bank's low-cost deposit base has so far shielded it from the full impact of rising rates, but as the 'Michiana' depositors become more rate-sensitive, the bank may need to increase deposit rates, which could compress margins. The loan-to-deposit ratio is not disclosed, but the strong deposit growth suggests there is room to fund loan expansion without pressure on funding costs.
