Why It Matters
These pro forma and historical financial statements let investors see how Investar’s consolidated results would look when combined with WFB’s reported operations for the referenced periods. The documents are part of the regulatory disclosure package (filed S-4 and 8-K/A) and provide the financial detail needed to evaluate the financial impact of the combination; investors should review Exhibit 99.1 and the incorporated WFB statements for specifics on assets, liabilities, and pro forma income. This filing is informational—providing financial detail—not an earnings release or an operational announcement.
