FIRST BUSEY CORPORATION

Shareholders of FIRST BUSEY CORPORATION

First Busey Corporation (Nasdaq: BUSE) is a publicly traded company, and U.S. securities law requires individual beneficial-ownership disclosure only for holders that cross the 5% threshold of a class of stock (Sections 13(d)/13(g) of the Securities Exchange Act of 1934). Based on Schedule 13G filings with the SEC, Wellington Management Group LLP reported beneficial ownership of 7,135,906 shares, representing 8.0% of the outstanding class, as of September 30, 2025, and BlackRock, Inc. reported beneficial ownership of 6,487,916 shares, representing 7.2% of the outstanding class, as of March 31, 2025. Both are SEC-registered investment advisers reporting shares held on behalf of client accounts and pooled investment funds rather than direct personal holdings; neither filing indicates an intent to influence control of the company. No other holder has been independently verified above the 5% disclosure threshold as of the most recent available filings.

Data availability

Officer and director information for First Busey Corporation is partial. As a Nevada-incorporated, Nasdaq-listed company, its officer and director disclosures are made primarily through SEC filings (proxy statements and Form 8-K reports) rather than a single state corporate registry, and complete historical appointment dates are not available for every director. Nationality is not disclosed for any officer or director in the reviewed sources. Separately, registry-sourced officer records associated with this company profile name individuals — including a Founder role and two differently addressed Treasurer entries in Illinois and Florida — that could not be independently matched to First Busey Corporation’s current board or executive team through SEC filings or company disclosures, and have therefore been excluded from this overview pending independent verification.

Group structure of FIRST BUSEY CORPORATION

First Busey Corporation is a publicly traded financial holding company and the ultimate parent of its corporate group; no controlling parent company was identified in SEC filings or state registry records. Its principal operating subsidiary is Busey Bank, which SEC filings describe as First Busey Corporation’s wholly-owned, Illinois state-chartered bank subsidiary. On March 1, 2025, First Busey Corporation completed its acquisition of CrossFirst Bankshares, Inc. and its subsidiary, CrossFirst Bank; the bank charters were then combined, with CrossFirst Bank merging into Busey Bank effective June 20, 2025, after which former CrossFirst Bank locations began operating as Busey Bank branches. SEC filings also disclose two earlier, completed bank acquisitions: Herget Financial Corporation and its subsidiary, Herget Bank, National Association (acquired 8 January 2015; Herget Bank merged into Busey Bank on 13 March 2015), and Pulaski Financial Corp. and its subsidiary, Pulaski Bank, National Association (acquired 30 April 2016; Pulaski Bank merged into Busey Bank on 4 November 2016). Both are historical relationships rather than current, separate operating subsidiaries. Group information is partial: registry data associated with this profile also lists numerous additional entities, including statutory trusts and real-estate holding companies, that plausibly relate to First Busey Corporation’s acquisition history but could not be individually verified against SEC filings or state registries within this review, and are therefore not presented as verified relationships below.

Its principal bank subsidiary and recent, completed acquisitions are independently confirmed through SEC filings and official company announcements; the broader set of entities appearing in registry data for this profile, including numerous statutory trusts and real-estate holding LLCs, could not be independently verified within this review and are not included in the relationships table above.
