 was classified as a PFIC in any taxable year in which a U.S. Holder held
Common Shares of the Company, such U.S. Holder will be subject to special rules with respect to any gain recognized under the Arrangement.

A foreign corporation will be considered a PFIC for any taxable year in which (1) 75% or more of its gross income is “passive
income” under the PFIC rules or (2) 50% or more of the average quarterly value of its assets produce (or are held for the production of) “passive income.” For this purpose, “passive income” generally includes
interest, dividends, certain rents and royalties, and certain gains. Moreover, for purposes of determining if the foreign corporation is a PFIC, if the foreign corporation owns, directly or indirectly, at least 25%, by value, of the shares of
another corporation, it will be treated as if it holds directly its proportionate share of the assets and receives directly its proportionate share of the income of such other corporation. If a corporation is treated as a PFIC with respect to a U.S.
Holder for any taxable year, the corporation will continue to be treated as a PFIC with respect to that U.S. Holder in all succeeding taxable years, regardless of whether the corporation continues to meet the PFIC requirements in
such years, unless certain elections are made.

The determination as to whether a foreign corporation is a PFIC is based on the
application of complex U.S. federal income tax rules, which are subject to differing interpretations, and the determination will depend on the composition of the income, expenses and assets of the foreign corporation from time to time and the nature
of the activities performed by its officers and employees. The Company believes that it was classified as a PFIC for the taxable year ending December 31, 2024 and in certain prior years, and expects to be classified as a PFIC for the
current taxable year. However, the Company’s actual PFIC status for the current taxable year is uncertain and cannot be determined until after the end of the taxable year.

If the Company is classified as a PFIC, a U.S. Holder that does not make any of the
elections described below would be required to report any gain recognized in connection with the receipt of the Consideration in the Arrangement as ordinary income, rather than as capital gain, and to allocate such gain ratably over each day in the
U.S. Holder’s holding period
