FirstSun and HomeStreet anticipate that subsequent events and developments will cause FirstSun’s and HomeStreet’s assessments to change. Neither FirstSun nor HomeStreet gives any assurance that either FirstSun or HomeStreet, or the combined company, will achieve the results or other matters set forth in the forward-looking statements.
