FORWARD-LOOKING INFORMATION

From time to time, National Bank and CWB make written and verbal forward-looking statements. Statements of this type are included in this press release and may be included in filings with Canadian and U.S. securities regulators or in other communications such as media releases and corporate presentations. Forward-looking statements in this press release may include, but are not limited to, statements regarding the payment of consent fees, the anticipated effects of the Preferred Share Amendments and the LRCN Amendments, the approval of the TSX in connection with the Preferred Share Amendments and the completion of the Transaction. Forward-looking statements are typically identified by the words “believe”, “expect”, “anticipate”, “intend”, “estimate”, “may increase”, “may impact”, “goal”, “focus”, “potential”, “proposed” and other similar expressions, or future or conditional verbs such as “will”, “should”, “would” and “could”.

By their very nature, forward-looking statements involve numerous assumptions and are subject to inherent risks and uncertainties, which give rise to the possibility that National Bank’s and/or CWB’s predictions, forecasts, projections, expectations, and conclusions will not prove to be accurate, that National Bank’s and/or CWB’s assumptions may not be correct, and that National Bank’s and/or CWB’s strategic goals will not be achieved. Assumptions underlying forward-looking statements included in this press release also include the terms and conditions of the consent solicitation and proposed amendments, the expected approval of the proposed amendments, the timing of completion of the Transaction and the conditions precedent to the closing of the Transaction (including the required regulatory approvals).

Forward-looking statements in this press release are based on a number of assumptions and are subject to risk factors, many of which are beyond National Bank’s and CWB’s control and the impacts of which are difficult to predict. These risk factors include, but are not limited to, the terms and conditions of the Preferred Share Amendments and LRCN Amendments (including the regulatory approvals required to implement such amendments); the impact of such amendments assuming that those are implemented; the intention to implement the proposed amendments following closing of the Transaction; the expected timing of completion of the Transaction and the conditions precedent to the closing of the Transaction (including the required regulatory approvals); that the Transaction will be completed on the terms currently contemplated; risk and uncertainties relating to the expected regulatory processes and outcomes in connection with the Transaction; National Bank’s inability to successfully integrate CWB upon completion of the Transaction; the possible delay or failure to close the Transaction; the potential delay or failure to realize the anticipated benefits from the Transaction; the potential failure to obtain the required approvals for the Transaction, including regulatory approvals, in a timely manner or at all; National Bank’s reliance upon publicly available information of CWB; potential undisclosed costs or liability associated with the Transaction; National Bank or CWB being adversely impacted during the pendency of the Transaction; and assumptions about future events, including economic conditions and proposed courses of action, based on National Bank and CWB management’s assessment of the relevant information available as of the date hereof; and National Bank’s and CWB’s ability to anticipate and manage the risks associated with these factors. It is important to note that the preceding list is not exhaustive of possible factors.

Additional information about certain factors and additional risk factors can be found in the “Risk Management” section of CWB’s 2023 Annual MD&A, in the “Risk Management” section of National Bank’s 2023 Annual Report, in the “Risk Management” section of National Bank’s Report to Shareholders for the third quarter of 2024, as well as in other reports and documents filed by National Bank and CWB with securities regulators or securities commissions from time to time and other documents that National Bank and CWB makes public. These and other factors should be considered carefully, and readers are cautioned not to place undue reliance on these forward-looking statements as a number of important factors could cause CWB’s and/or National Bank’s actual results to differ materially from the expectations expressed in such forward-looking statements. Any forward-looking statements contained in this press release represent CWB’s and National Bank’s views as of the date hereof. Unless required by law, neither CWB or National Bank undertake to update any forward-looking statement, whether written or verbal, that may be made from time to time by or on behalf of CWB or National Bank. CWB and National Bank caution investors that these forward-looking statements are not guarantees of future performance and that actual events or results may differ significantly from these statements due to a number of factors.
