In addition to three Council of Aboriginal Businesses and is a Committed Canadian acquisitions since 2019 (250+ current member of the Progressive Aboriginal Relations Canadian sta昀昀), Westinghouse continues to program. Westinghouse’s reconciliation journey is invest in the country and will be opening a global supported by our Indigenous Relations Committee, engineering and innovation hub in Kitchener Indigenous Relations policy and DEI initiatives. in May of 2024 for 200+ engineers and sta昀昀. Canadian Footprint Canadian Supply Chain Serving Westinghouse has a deep commitment to Canada, AP1000 Reactors Worldwide with three o昀케ces in Burlington, one in Kitchener • Westinghouse intends to implement its proven (May ’24), one in Port Elgin, and a manufacturing localization approach using Canada’s world facility in Peterborough, Ontario. Westinghouse class nuclear supply chain, for both Canadian gives back to the communities where our employees projects and to support international projects. live and work through charitable donations, • The Canadian AP1000 supply chain will provide scholarships and awards, and volunteering. Canadian 昀椀rms opportunities to support the over 30 AP1000 units Westinghouse has clear line of sight to. No other Western reactor technology has such tangible, substantial growth opportunities. Clean, Affordable Energy for the Ratepayers Westinghouse’s fully designed and readily deployable AP1000 reactor eliminates the First of a Kind (FOAK) design/licensing/construction risks that have plagued new-nuclear and can be on the grid far sooner than any FOAK technology. © 2023 Westinghouse Electric Company LLC.

Why AP1000 Technology Reactor Design, Licensing, Performance • The AP1000 “nuclear island” design is complete and standardized, which greatly reduces the risk to cost and 1 schedule associated with new-nuclear. • Proven technology bene昀椀ting from Nth of a Kind (NOAK) experience - 5 current operating reactors (soon to be 6), with 6 more under construction, and contracts for 13 more in place or being negotiated. Worldwide, a 昀氀eet of 12 AP1000 reactors will be in operation by 2030, before the build-up already committed to in Central/Eastern Europe. • Demonstrated record-setting performance levels with a capacity factor greater than 92%. • Has already been licensed by three di昀昀erent global nuclear regulatory bodies — USA, Europe, China. Reactor Construction and Build • To add emissions-free power to the grid by the 2030s, the AP1000 technology is overwhelmingly the best Canadian-owned and Canadian-supplied solution for the country and its ratepayers. • Canada will benefit from the engineering and constructability experience Westinghouse gained from Chinese and U.S. projects. This experience is being incorporated into our Polish, Bulgarian and Ukrainian projects and is invaluable, as bringing a new reactor from concept to operating reality is very challenging.
