Comment for Type of Reporting Person: This Statement on Schedule 13G/A (the "Schedule 13G/A") is being filed on behalf of (i) Ice Mountain LLC, a Delaware limited liability company ("Ice Mountain"); (ii) Cascade Bay LLC, a Delaware limited liability company ("Cascade Bay"), for itself and as the Manager of Ice Mountain; (iii) Katz 2004 DYN Trust ("DYN"), the Special Assets Manager of Cascade Bay; (iv) Katz New VBA Trust ("New VBA"); (v) Katz Voting Stock Trust, a formerly revocable trust ("KVST"); (vi) Aimee Katz, individually and with April Jalazo, the seat holders of each of the voting committees with the power to direct DYN, New VBA and KVST (each, a "Voting Committee" and collectively, the "Voting Committees"); and (vii) April Jalazo, individually and with Aimee Katz, the seat holders of the Voting Committees (each individually, a "Reporting Person", and collectively, the "Reporting Persons"), related to the common stock, par value $0.01 per share (the "Common Stock"), of Zurn Elkay Water Solutions Corporation, a Delaware corporation (the "Issuer"). Ice Mountain acquired its shares in the Issuer as a result of the combination of Zurn Water Solutions Corporation ("Zurn") and Elkay Manufacturing Company ("Elkay") in 2022. Ice Mountain's holdings in Zurn represent the interests of those members of the Katz family (the founding family of Elkay), who owned a controlling interest in Elkay (a family-owned business formed in 1920) immediately before merging with Zurn. The family members that Ice Mountain represents have expressed their desire that Ice Mountain continue to be an investor in the Issuer for the long-term, with no current plans for Ice Mountain to further diversify Ice Mountain's remaining holdings, and as such, Ice Mountain has entered into a lock-up agreement for Ice Mountain's remaining shares that expires October 31, 2026.
