The transaction is immediately accretive to Plumas's balance sheet, boosting pro forma assets to $2.3 billion, loans to $1.5 billion, and deposits to $1.9 billion, representing a significant increase driven by Cornerstone's $648 million in assets. The positive market reaction, evidenced by a 1.53% increase in PLBC's share price to $47.64, underscores investor confidence in the deal's rationale.

This retention of local market expertise, particularly in credit and lending, is crucial for a smooth operational consolidation and is intended to pair Cornerstone's strong community ties with Plumas's existing technological and small business lending platforms, aiming to drive long-term shareholder value.

Key Decisions for Investors

• Investors should view the completed acquisition as a positive fundamental development for Plumas Bancorp, as the significant expansion of its asset base and Northern California presence is poised to drive future revenue and earnings growth.
• Monitor the integration process over the next few quarters, paying close attention to metrics such as deposit retention, loan growth in the new markets, and the realization of any stated cost or revenue synergies.
• The retention of key Cornerstone executives in senior roles significantly de-risks the merger execution, suggesting investors should have higher confidence in the combined entity's ability to maintain client relationships and local market share.
