Exhibit 99.1

CAE announces pricing of marketed public offering

• Price to the public of US$27.50 per share for gross proceeds of US$250 million, with 15% Over Allotment Option

• Use of proceeds to partly fund the previously announced acquisition of L3Harris Technologies’ Military Training business

Montreal, Canada, March 9, 2021 - (NYSE: CAE; TSX: CAE) - CAE Inc. (“CAE” or the “Corporation”) today announced the pricing of its previously announced underwritten marketed public offering of common shares in the United States and Canada (the “Offering”). The Offering is comprised of 9,090,909 common shares at a price to the public of US$27.50 per share.

The Offering is being conducted through a syndicate of underwriters led by Goldman Sachs & Co. LLC, TD Securities Inc., RBC Capital Markets, and Scotia Capital (USA) Inc. as joint bookrunners (collectively, the “Underwriters”).

CAE has also granted the Underwriters an option to purchase up to 1,363,636 additional common shares, representing in the aggregate 15% of the number of common shares to be sold pursuant to the Offering, solely to cover the Underwriters’ over-allocation position, if any, and for market stabilization purposes. The option is exercisable by the Underwriters for a period of 30 days following the closing of the Offering.

CAE intends to use the net proceeds of the Offering to finance a portion of the purchase price and related costs of its previously announced acquisition of L3Harris Technologies’ Military Training business (the “Acquisition”). CAE expects to fund the balance of the purchase price and related costs of the Acquisition with the net proceeds from its previously completed private placements of C$700 million (approximately US$550 million) aggregate amount of subscription receipts to two institutional investors, and from currently available liquidities, including cash on hand and/or advances or drawdowns under one or more of its senior credit facilities or other debt financing. Pending their use, CAE intends to invest the net proceeds from the Offering in short-term, investment grade, interest bearing instruments or hold them as cash or cash equivalents, and repay a portion of the indebtedness outstanding under one of more of its senior credit facilities. The Offering is not contingent on the closing of the Acquisition. If for any reason the Acquisition does not close, CAE intends to use the net proceeds from the Offering for general corporate purposes, which may include the financing of future potential acquisition and growth opportunities.

In connection with the Offering, CAE filed the preliminary prospectus supplement, and will file a final prospectus supplement, to its short form base shelf prospectus dated November 19, 2020 with the securities regulatory authorities in each of the provinces of Canada. The preliminary prospectus supplement has also been filed, and the final prospectus supplement will be filed, with the U.S. Securities and Exchange Commission (the “SEC”) as part of CAE’s registration statement on Form F-10 in accordance with the multi-jurisdictional disclosure system established between Canada and the United States.

Closing of the Offering is subject to customary closing conditions, including the approvals of the Toronto Stock Exchange and the New York Stock Exchange, and is expected to occur on March 12, 2021.

The Offering is being made in Canada only by means of the short form base shelf prospectus and the prospectus supplement and in the United States only by means of CAE’s registration statement. Such documents contain important information about the Offering. A copy of the Canadian prospectus supplement and short form base shelf prospectus can be found on SEDAR at www.sedar.com, and a copy of the U.S. prospectus supplement and the registration statement can be found on EDGAR at www.sec.gov.

Caution concerning forward-looking statements

This press release includes forward-looking statements, which include, without limitation, statements relating to the Offering; the Acquisition; available liquidities; proceeds of debt financing; the use of proceeds of the Offering; the expected timing of, and conditions precedent to, completion of the Offering and the Acquisition; general economic outlook; prospects and trends of an industry; and other statements that are not historical facts. Although CAE believes that the expectations and assumptions on which such forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements since no assurance can be given that they will prove to be correct.

Forward-looking statements can generally be identified by the use of forward-looking terminology such as “believe”, “expect”, “anticipate”, “plan”, “intend”, “continue”, “estimate”, “may”, “will”, “should”, “strategy”, “future” and similar expressions. All such forward-looking statements are made pursuant to the ‘safe harbour’ provisions of applicable Canadian securities laws and of the United States Private Securities Litigation Reform Act of 1995.

By their nature, forward-looking statements require us to make assumptions and are subject to inherent risks and uncertainties associated with our business which may cause actual results in future periods to differ materially from results indicated in forward-looking statements, including risks and uncertainties relating to the following: the failure to receive regulatory approvals (including stock exchange) or otherwise satisfy the conditions to the completion of the Offering or

delay in completing the Offering and the funds thereof not being available to CAE in the time frame anticipated or at all; the occurrence of an event which would allow the Underwriters to terminate their obligations under the Underwriting Agreement; the failure to close the Acquisition or change in the terms of the Acquisition; the uncertainty of obtaining in a timely manner, or at all, the requisite regulatory approvals required to complete or otherwise satisfy the closing conditions of the Acquisition; unfavourable capital markets developments or other factors that may adversely affect CAE’s ability to complete the Offering or finance the Acquisition; increased indebtedness; the fact that CAE does not currently own or control L3Harris Military Training; the nature of acquisitions; exchange rate and foreign currency exposure risks. The foregoing list is not exhaustive and other unknown or unpredictable factors could also have a material adverse effect on the performance or results of CAE. The completion of the Offering and the completion of the Acquisition (which are not contingent upon each other) are both subject to customary closing conditions, termination rights and other risks and uncertainties, including, without limitation, regulatory approvals, and there can be no assurance that either the Offering or the Acquisition will be completed.

These statements are not guarantees of future performance or events, and we caution you against relying on any of these forward-looking statements. While management considers these assumptions to be reasonable and appropriate based on information currently available, there is risk that they may not be accurate. The forward-looking statements contained in this press release describe our expectations as of March 9, 2021 and, accordingly, are subject to change after such date. Except as required by law, we disclaim any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise. The forward-looking information and statements contained in this press release are expressly qualified by this cautionary statement. Except as otherwise indicated by CAE, forward-looking statements do not reflect the potential impact of any special items or of any dispositions, monetizations, mergers, acquisitions, other business combinations or other transactions that may occur after March 9, 2021. The financial impact of these transactions and special items can be complex and depends on the facts particular to each of them. We therefore cannot describe the expected impact in a meaningful way or in the same way we present known risks affecting our business. Forward-looking statements are presented in this press release for the purpose of assisting investors and others in understanding certain key elements of the Offering and the Acquisition. Readers are cautioned that such information may not be appropriate for other purposes.

Material assumptions

The forward-looking statements set out in this press release are based on certain assumptions including, without limitation: the satisfaction of all closing conditions and the successful completion of the Offering within the anticipated timeframe, including receipt of regulatory approvals (including stock exchange approvals), fulfilment by the Underwriters of their obligations pursuant to the Underwriting Agreement, that no event will occur which would allow the Underwriters to terminate their obligations under the Underwriting Agreement, our liquidity from our cash and cash equivalents, undrawn amounts on our revolving credit facilities, the balance available under our receivable purchase program, our cash flows from operations and continued access to debt funding will be sufficient to meet financial requirements in the foreseeable future, and no material financial, operational or competitive consequences of changes in regulations affecting our business. For additional information, including with respect to other assumptions underlying the forward-looking statements made in this press release, refer to the applicable reportable segment in CAE’s Management’s Discussion & Analysis for the year ended March 31, 2020 (the “MD&A”). Given the impact of the changing circumstances surrounding the COVID-19 pandemic and the related response from CAE, governments, regulatory authorities, businesses and customers, there is inherently more uncertainty associated with CAE’s assumptions.

Accordingly, the assumptions outlined in this press release, and in the documents referenced herein and, consequently, the forward-looking statements based on such assumptions, may turn out to be inaccurate. As it relates to the Acquisition, the assumptions underlying the forward-looking statements made in this press release include, without limitation, the receipt of all requisite regulatory approvals required to complete the Acquisition in a timely manner and on terms acceptable to CAE; economic and political environments and industry conditions; the accuracy and completeness of public and other disclosure (including financial disclosure) by L3Harris; the ability of CAE to opportunistically access the capital markets

before or after the closing of the Acquisition and absence of material change in market conditions; the ability to hedge exposures to fluctuations in interest rates and foreign exchange rates; the maintenance of CAE’s investment grade credit rating; as well as management’s estimates and expectations in relation to future economic and business conditions and other factors in relation to the Acquisition.

Other Material risks

Other important risk factors that could cause actual results or events to differ materially from those expressed in or implied by our forward-looking statements are set out in the MD&A filed by CAE with the Canadian Securities Administrators (available at www.sedar.com) and with the U.S. Securities and Exchange Commission (available at www.sec.gov). The MD&A is also available at www.cae.com. Any one or more of the factors set out in the MD&A may be exacerbated by the growing COVID-19 outbreak and may have a significantly more severe impact on CAE’s business, results of operations and financial condition than in the absence of such outbreak. Accordingly, readers are cautioned that any of the disclosed risks could have a material adverse effect on our forward-looking statements. We caution that the disclosed list of risk factors is not exhaustive and other factors could also adversely affect our results.
