Nemaska Lithium Announces Closing of Subscription Receipt Financing With SoftBank Group

QUEBEC CITY, Apr 25, 2018 - Nemaska Lithium Inc. ("Nemaska Lithium" or the "Corporation") (TSX:NMX) (OTCQX:NMKEF) (FRANKFURT:N0T) is pleased to announce that it has closed its previously announced private placement (the "Placement") of 88,460,446 subscription receipts (the "Receipts") at a price of CAD 1.12 per Receipt for aggregate gross proceeds of CAD 99,075,700, pursuant to the investment agreement (the "Investment Agreement") entered into with SoftBank Group Corp. ("SoftBank") on April 5, 2018.

Pursuant to the Placement, upon conversion of the Receipts, SoftBank will acquire up to 9.9% of Nemaska Lithium's common shares ("Shares"). The gross proceeds from the Placement have been placed in escrow, pending satisfaction or waiver of the remaining escrow release conditions, being, among others, the completion by the Corporation of one or more public and/or private equity offerings (the "Equity Offerings"), and the reception of irrevocable commitments for debt financing as per the details given in its April 5, 12 and 20, 2018 press releases (see : http://www.nemaskalithium.com/en/investors/press-releases/2018/).

If the escrow release conditions are satisfied or waived, each Receipt shall be automatically converted into one (1) Share and the net proceeds of the Placement will be released to the Corporation. If the escrow release conditions have not been satisfied or waived by August 6, 2018, the Receipts will be automatically cancelled and funds will revert to SoftBank. If, after giving effect to the Placement and the completion of the Equity Offerings, SoftBank would hold more than 9.9% of the Shares outstanding on the escrow release date, the Receipts that would result in such excess will be cancelled such that SoftBank will hold no more than 9.9% of the Shares outstanding at such time (and the corresponding proceeds will revert to SoftBank). The full text of the subscription receipt agreement governing the Receipts is available on SEDAR at www.sedar.com.

Cautionary Statement on Forward-Looking Information

All statements, other than statements of historical fact, contained in this press release including, but not limited to, those relating to the fulfillment of the escrow release conditions of the Receipts and the receipt by the Corporation of the net proceeds from the Placement, constitute "forward-looking information" and "forward-looking statements" within the meaning of certain securities laws and are based on expectations and projections as of the date of this press release. Certain important assumptions by the Corporation in making forward-looking statements include, but are not limited to, the satisfaction, in a timely manner, by the Corporation of conditions precedent to (a) the release of the Placement proceeds from escrow and (b) the closing of each component of the overall project financing, including regulatory (and TSX) approval.

Forward-looking statements contained in this press release are based on expectations, estimates and projections as of the time of this press release. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the Corporation as of the time of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. These estimates and assumptions may prove to be incorrect.

Many of these uncertainties and contingencies can directly or indirectly affect, and could cause, actual results to differ materially from those expressed or implied in any forward-looking statements. There can be no assurance that the Placement as well as any component of the financing transactions will be completed, as the next steps and, eventually, the actual results of financing endeavors, in particular as regards the debt financing and the equity offerings, and future events could differ materially from those anticipated in such statements.

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that estimates, forecasts, projections and other forward-looking statements will not be achieved or that assumptions do not reflect future experience. Forward-looking statements are provided for the purpose of providing information about management's endeavors to complete its project financing and, more generally, its expectations and plans relating to the future. Readers are cautioned not to place undue reliance on these forward-looking statements as a number of important risk factors and future events could cause the actual outcomes to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates, assumptions and intentions expressed in such forward-looking statements. All of the forward-looking statements made in this press release are qualified by these cautionary statements and those made in our other filings with the securities regulators of Canada including, but not limited to, the cautionary statements made in the "Risk Factors" section of the Corporation's Annual Information Form dated October 5, 2017 and the "Risk Exposure and Management" section of the Corporation's quarterly Management Discussion & Analysis. The Corporation cautions that the foregoing list of factors that may affect future results is not exhaustive, and new, unforeseeable risks may arise from time to time. The Corporation disclaims any intention or obligation to update or revise any forward-looking statements or to explain any material difference between subsequent actual events and such forward-looking statements, except to the extent required by applicable law.
