The rules require disclosure of, among other

material climate-related risks;

activities to mitigate or adapt to such risks;

governance and management of such risks;

and material greenhouse gas emissions from operations owned or controlled (Scope 1) and/or indirect emissions from purchased energy

consumed in operations (Scope 2).

Additionally, the rules require disclosure in the notes to the financial statements of the effects

of severe weather events and other natural conditions, subject to certain materiality thresholds.

As a smaller reporting company,

the rules will become effective on a phased-in timeline starting in fiscal years beginning in calendar year 2027, which for us

is fiscal 2028.

life of 2.0 years, a risk-free interest rate of 4.33 %, an expected volatility of 54.8 %, and an expected dividend rate of 0 %.

In connection with the closing

of the previously disclosed business combination transaction (the “Transaction”) on March 17, 2023 (the “Transaction

Closing”), 4,565,808 shares of Class B common stock of ECRC were vested as of the Transaction Closing (the “Vested

Shares”) and are exchangeable for Common Shares on a one-for-one basis at any time, and from time to time, until the tenth

anniversary of the Transaction Closing.

On February 29, 2024, 243,692 Vested Shares were exchanged for an equivalent number of

Common Shares.

This exchange resulted in a change in the Company’s ownership interest in ECRC and was accounted for as an

equity transaction in accordance with ASC 810-10-45-23, with no gain or loss recognized.

Accordingly, the carrying amount of the

noncontrolling interest was adjusted to reflect the change in the Company’s ownership interest with a corresponding offset

booked to equity.

Prior to January 1, 2024, the

Company concluded that under ASU 718, Compensation – Stock Compensation (Topic 718) , Options previously issued on December

31, 2021, May 30, 2022, and March 27, 2023, which included a C$ strike price should remain equity-classified as management determined

that the Options qualified for an exemption from liability classification as the Options were denominated in a currency in which

a substantial portion of the Company’s equity securities traded.

Effective January 1, 2024, the Company determined that

due to historically decreasing trading volume on the Toronto Stock Exchange (the “TSX”), this exemption no longer

applied and accordingly, these Options were classified as a liability based on their fair values on that date.

The Company recorded

a mark-to-market gain of $195 in other operating expenses related to these option liabilities for the three-month period ended

March 31, 2024.

On March 28, 2024, the Company’s

Board of Directors (the “Board”) approved a modification to Options previously issued on March 27, 2023, with dual

strike prices of $6.95 and C$9.52, under which the option to exercise in C$ was removed.

No other terms or conditions were amended

by the Board.

Based on this amendment, the Company re-classified these Options to equity on March 28, 2024, based on their fair

value on that date.
