REASONS FOR THE OFFER

SC2 is making the Offer following recent engagements with management and the board of Sherritt. SC2 encourages shareholders to consider the following factors, among others, when making the decision to accept the Offer:

• As a result of the Offer, shareholders will receive immediate liquidity at a premium to the current trading price of the common shares.
• SC2 believes that, in the absence of a motivated large shareholders, it seems unlikely that Sherritt's performance will improve. SC2 is prepared to take an active role in ensuring the future success of Sherritt, for the benefit of all shareholders.

DETAILS OF THE OFFER

The Offer is open for acceptance until 5:00 p.m. ( Calgary time) on Friday, May 10, 2024 , provided however that SC2 reserves the right, in its sole and absolute discretion at any time, to: (i) extend or vary the Offer at any time; or (ii) withdraw the Offer if the conditions thereto are not met, and if withdrawn, it will not be required to take up or pay for common shares delivered pursuant to the Offer.

If the Offer is withdrawn by SC2, SC2 shall cause all common shares delivered pursuant to the Offer to be returned to the shareholders. Full details of the Offer are included in the Letters, including complete instructions for the tendering and delivery of common shares to SC2. In order to deposit their common shares to the Offer, registered shareholders must complete the documentation as set out in the Letter of Transmittal and beneficial shareholders must follow the instructions provided by their investment dealer, broker or other nominee. Investment dealers, brokers and other nominees may set a deadline for the delivery of deposit instructions that is earlier than the Expiry Time, and as such shareholders should contact their investment dealer, broker or other nominee for assistance at their earliest convenience. Deposited common shares may be withdrawn at any time prior to the time they are taken up by SC2.

The Offer will be subject to certain conditions set out in the Letters which, unless waived, must be satisfied. The Letters will require that each depositing shareholder whose common shares are taken up and paid for appoint representatives of SC2 as its nominees and proxy for any upcoming shareholders' meeting.

If more than the maximum number of common shares for which the Offer is made are delivered in accordance with the Offer and not withdrawn at the time of take up of the common shares, the common shares to be purchased from each depositing shareholder will be determined on a pro rata basis according to the number of common shares delivered by each shareholder, disregarding fractions, by rounding down to the nearest whole number of common shares.

FORWARD-LOOKING STATEMENTS

Certain statements contained in this press release, including statements regarding taking up and paying for common shares deposited under the Offer contain "forward-looking statements" and are prospective in nature. Forward-looking statements are not based on historical facts, but rather on current expectations and projections about future events, and are therefore subject to risks and uncertainties that could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as "plans", "expects", "intends", "anticipates", or variations of such words and phrases or statements that certain actions, events or results "may", "could", "should", "would", "might" or "will" be taken, occur or be achieved. Although SC2 believes that the expectations reflected in such forward-looking statements are reasonable, such statements involve risks and uncertainties, and undue reliance should not be placed on such statements. Material factors or assumptions that were applied in formulating the forward-looking information contained herein include the assumption that the business and economic conditions affecting Sherritt's operations will continue substantially in the current state, including, without limitation, with respect to industry conditions, general levels of economic activity, continuity and availability of personnel and third party service providers, local and international laws and regulations, foreign currency exchange rates and interest rates, inflation, and taxes, and that there will be no unplanned material changes to Sherritt's facilities, operations and customer and employee relations. SC2 cautions that the foregoing list of material factors and assumptions is not exhaustive. Many of these assumptions are based on factors and events that are not within the control of SC2 and there is no assurance that they will prove correct. Important factors that could cause actual results, performance or achievements to differ materially from those expressed or implied by such forward-looking statements include, among other things, actions taken by Sherritt in respect of the Offer, the failure to satisfy the conditions of the Offer, industry risk and other risks inherent in the running of the business of Sherritt, foreign currency exchange rates and interest rates, general economic conditions, legislative or regulatory changes, changes in income tax laws, and changes in capital or securities markets. These are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of SC2's forward-looking statements. Other unknown and unpredictable factors could also impact its results. Many of these risks and uncertainties relate to factors beyond SC2's ability to control or estimate precisely. Consequently, there can be no assurance that the actual results or developments anticipated by SC2 will be realized or, even if substantially realized, that they will have the expected consequences for, or effects on, SC2 or Sherritt and their respective future results and performance. Forward-looking statements in this press release are based on SC2's beliefs and opinions at the time the statements are made, and there should be no expectation that these forward- looking statements will be updated or supplemented as a result of new information, estimates or opinions, future events or results or otherwise, and SC2 disavows and disclaims any obligation to do so, except as required by applicable law.

THIS PRESS RELEASE IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT AN OFFER OR SOLICITATION TO PURCHASE SECURITIES IN ANY JURISDICTION IN WHICH, OR TO OR FROM ANY PERSON TO OR FROM WHOM, IT IS UNLAWFUL TO MAKE SUCH OFFER OR SOLICITATION UNDER APPLICABLE SECURITIES OR OTHER LAWS. THE OFFER IS BEING MADE SOLELY PURSUANT TO THE LETTERS, WHICH SET FORTH THE COMPLETE TERMS OF THE OFFER THAT SHAREHOLDERS SHOULD CAREFULLY READ PRIOR TO MAKING ANY DECISION.
