Explanatory Note
Item 1.01 Entry into a Material Definitive Agreement.
Entry into Board Representative Letter Agreement
On December 3, 2025, FirstSun Capital Bancorp (the “Company”) entered into a Board Representative Letter Agreement with Castle Creek Capital Partners IX, LP (“Castle Creek”) that provides, beginning with the earlier of (i) the closing of the Company’s proposed merger with First Foundation Inc. (the “Proposed Merger Closing”) and (ii) the 2026 Annual Meeting of the Stockholders of the Company (the “2026 Annual Meeting”) the Company will use its best efforts to cause an individual designated for nomination by Castle Creek to be elected or appointed to the board of directors of the Company and will recommend to its stockholders the election of such individual designated at the applicable stockholders’ meetings of the Company. In addition, as of the date of the Board Representative Letter Agreement, to the extent Castle Creek does not have a board representative currently serving on the board of directors, Castle Creek may appoint an individual as a nonvoting observer to the board of directors. Such nomination and observer rights continue for so long as Castle Creek owns at least 40% of the total shares held by Castle Creek as of the date of the Board Representative Letter Agreement. The Board Representative Letter Agreement entered into with Castle Creek is substantially similar to the form of Board Representation Letter Agreements entered into with other stockholders of the Company as described in the Company’s Current Report on Form 8-K filed with the Securities Exchange Commission on February 25, 2025.
The foregoing description of the Board Representative Letter Agreement is not complete and is subject to and qualified in its entirety by reference to the full text of such agreement, a copy of which was included as Exhibit 4.1 to the Original Report.
Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On December 3, 2025, Isabella Cunningham announced her intention to resign as a director of the Company with such resignation being effective as of the earlier of (i) the Proposed Merger Closing and (ii) the 2026 Annual Meeting.
Ms. Cunningham has served as a valuable board member of the Company since 2022. In her letter of resignation, Ms. Cunningham expressed her pleasure in serving on the Board of the Company and wished continued success to the Company after her resignation. The Company similarly appreciates her contributions during her tenure. The Company thanks Ms. Cunningham for her service to the Company and wishes her the best in her endeavors following her resignation from the board.
The Company does not anticipate reducing the size of the board upon Ms. Cunningham’s resignation but intends to keep the size of the Board the same in order to accommodate the board nominee of Castle Creek at the earlier of the Proposed Merger Closing and the 2026 Annual Meeting.
Item 8.01 Other Events.
On December 4, 2025, the Company and Castle Creek issued a joint press release announcing Castle Creek’s investment in the Company and related board representation arrangement. A copy of the press release was furnished as Exhibit 99.1 to the Original Report.
