**Forward Looking Statements "Safe Harbor" Statement Under the Private Securities Litigation Reform Act of 1995.**

Statements included in this communication which are not historical in nature are intended to be, and hereby are identified as, "forward-looking statements" within the meaning, and subject to the protections of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact are forward-looking statements. Examples of forward-looking statements include, but are not limited to, statements regarding the outlook, benefits and expectations of FirstSun and First Foundation with respect to the proposed merger, including future financial and operating results (including the anticipated impact of the proposed merger on First Foundation's and FirstSun's respective earnings and tangible book value), and the expected timing of the closing of the merger. These statements reflect management's current expectations and are not guarantees of future performance. Words such as "may," "will," "believe," "anticipate," "expect," "intend," "opportunity," "continue," "should," and "could" and variations of such words and similar expressions are intended to identify such forward-looking statements. Forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results. Such risks, uncertainties and assumptions, include, among others, the following:

&nbsp;&nbsp;&nbsp;&nbsp;· the failure to obtain necessary
regulatory approvals when expected or at all (and the risk that such approvals may result in the imposition of conditions that could adversely
affect the combined company or the expected benefits of the proposed transaction);

&nbsp;&nbsp;&nbsp;&nbsp;· the failure of First Foundation
or FirstSun to obtain the required stockholder approval, or the failure of either party to satisfy any of the other closing conditions
on a timely basis or at all;

&nbsp;&nbsp;&nbsp;&nbsp;· the occurrence of any event,
change or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;· the possibility that the
proposed transaction will not be completed as planned, including the anticipated benefits of the proposed transaction;

&nbsp;&nbsp;&nbsp;&nbsp;· diversion of 'management's
attention from ongoing business operations and opportunities;

&nbsp;&nbsp;&nbsp;&nbsp;· potential adverse reactions
or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed transaction;

&nbsp;&nbsp;&nbsp;&nbsp;· the outcome of any legal proceedings that may
be instituted against FirstSun or First Foundation;

&nbsp;&nbsp;&nbsp;&nbsp;· the risk that the cost
savings and synergies expected from the proposed transaction may not be realized or may take longer than anticipated to be realized;

&nbsp;&nbsp;&nbsp;&nbsp;· the risk that integration
of FirstSun's and First Foundation's respective businesses may be materially delayed or more costly or difficult than expected,
including as a result of unexpected factors or events;

&nbsp;&nbsp;&nbsp;&nbsp;· changes to tax legislation
and their potential effects on the accounting for the merger;

&nbsp;&nbsp;&nbsp;&nbsp;· the possibility of dilution
to existing shareholders resulting from the issuance of additional shares in connection with the proposed transaction;

&nbsp;&nbsp;&nbsp;&nbsp;· the possibility that the
combined company may be subject to additional regulatory requirements as a result of the merger or expansion of its business operations;
and

&nbsp;&nbsp;&nbsp;&nbsp;· other factors that may
affect future results of FirstSun or First Foundation including changes in asset quality and credit risk; the inability to sustain revenue
and earnings growth; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices;
the impact, extent and timing of technological changes; capital management activities; and actions of the Federal Reserve Board and legislative
and regulatory actions and reforms.

Further information regarding additional factors that could affect the forward-looking statements can be found in the cautionary language included under the headings "Cautionary Note Regarding Forward-Looking Statements" (in the case of FirstSun), "Forward-Looking Statements" (in the case of First Foundation), and "Risk Factors" in FirstSun's and First Foundation's Annual Reports on Form 10-K for the year ended December 31, 2024 (available at [https://www.sec.gov/ix?doc=/Archives/edgar/data/0001709442/000170944225000008/fcb-20241231.htm](https://www.sec.gov/ix?doc=/Archives/edgar/data/0001709442/000170944225000008/fcb-20241231.htm) and [https://www.sec.gov/ix?doc=/Archives/edgar/data/0001413837/000155837025003129/ffwm-20241231x10k.htm](https://www.sec.gov/ix?doc=/Archives/edgar/data/0001413837/000155837025003129/ffwm-20241231x10k.htm), respectively), and other documents subsequently filed by FirstSun and First Foundation with the Securities and Exchange Commission (the "SEC").
