Toronto Stock Exchange Announces the 2023 TSX30®, Celebrating Excellence in Growth

September 12, 2023 (TORONTO) – Toronto Stock Exchange (TSX) today released its 2023 TSX30^®, an annual ranking of the 30 top-performing stocks over a three-year period, showcasing particularly strong representation from the natural resources sector for the second consecutive year. Highlights from this year include: the resilient oil and gas sector making up over 50% of the list; significant Canadian presence, with 27 companies headquartered in Canada; and the continued success of graduates from TSX Venture Exchange (TSXV) to TSX, with 12 companies on the list.

The flagship TSX30 program, established in 2019, recognizes the success of TSX's listed companies. TSX represents a growth opportunity for all publicly-listed companies. The companies featured on the 2023 list averaged 553% share price appreciation, accounting for over $120 billion of value creation.

"This year's TSX30 emphasizes the critical role that Canadian resource companies continue to play at home and abroad, as well as the importance of oil and gas in the world's energy mix for years to come," said Loui Anastasopoulos, CEO, Toronto Stock Exchange. "Canada has historically been a global leader in energy and we are now establishing a similar position in energy transition. TSX will continue to be a platform for this emerging sector, enabling listed companies and investors to capitalize on the long-term growth opportunities related to energy transition, powering Canada's economy for generations to come."

A recurring theme of TSX30 reinforces the important role TSX plays in a company's lifecycle – from early stage to established capital markets participant. This is the fourth year in a row that more than a third of the list are graduates of TSXV.

"We are proud to celebrate the tremendous success of these 30 companies and we congratulate them all for their remarkable growth. The TSX30 points to the overall strength of Canada's ever-evolving public markets, and the efficacy of this powerful ecosystem in driving growth for issuers, investors and the overall economy," added Anastasopoulos.

Other highlights from the 2023 ranking include:

• Sector standouts: Seven of the 30 companies represent the mining sector, with an average price increase of 615% and a 442% market capitalization increase. The industrial products & services sector is also represented by seven companies on this list. Together, they averaged a 423% price increase and 425% market capitalization increase.

• Index representation: Out of the seven mining companies on the list, five are included in the S&P/TSX Battery Metals Index* and five are in the newly launched S&P/TSX Energy Transition Materials Index*.
