risks of lending activities, which may be affected by deterioration in real estate markets and the financial condition of borrowers, and the operational risk of lending activities, including the effectiveness of our underwriting practices and
the risk of fraud, any of which may lead to increased loan delinquencies, losses, and non-performing assets, and may result in our allowance for credit losses not being adequate; (iv) fluctuations in the demand for loans, and fluctuations in
commercial and residential real estate values in our market area; (v) the quality and composition of our securities portfolio; (vi) our ability to develop and maintain a strong core deposit base, including among our venture banking clients,

potential adverse reactions of the Company’s or PacWest’s customers, suppliers, vendors, employees or other business partners; (x) results of examinations by regulatory authorities of the Company and the possibility that any such regulatory
authority may, among other things, limit our business activities, restrict our ability to invest in certain assets, refrain from issuing an approval or non-objection to certain capital or other actions, increase our allowance for credit
losses, result in write-downs of asset values, restrict our ability or that of our bank subsidiary to pay dividends, or impose fines, penalties or sanctions; (xi) legislative or regulatory changes that adversely affect our business, including
changes in tax laws and policies, accounting policies and practices, privacy laws, and regulatory capital or other rules; (xii) the risk that our enterprise risk management framework may not be effective in mitigating risk and reducing the
