Corporate Leadership

Tim Cook to step down as Apple CEO in September, Ternus takes over

Apple confirmed Tim Cook will leave the chief executive role in September, becoming executive chairman of the board. John Ternus, currently senior vice president of hardware engineering, will take over as CEO. Cook's 15-year tenure saw Apple's market value rise by more than $3.6 trillion.

Why it matters

Analysis: The succession puts a hardware engineer at the helm of a company under intense pressure to prove its AI credentials. Ternus has no public track record running a consumer software or services business, raising immediate questions about strategic continuity and whether Apple can close the gap on rivals in generative AI.

Artificial Intelligence

Anthropic's new AI model exposes thousands of critical software vulnerabilities

Anthropic's latest model, Mythos, has drawn warnings from cybersecurity experts and the banking sector after the company said the model's preview had uncovered thousands of major vulnerabilities across every major operating system and web browser. The findings are fuelling concern about the model's potential use as an offensive security tool.

Why it matters

Analysis: A model capable of autonomously identifying thousands of critical vulnerabilities at scale represents a step-change in cyber risk for financial institutions, which rely on the underlying operating systems and browsers now flagged. Expect immediate scrutiny of AI deployment policies and third-party risk frameworks across regulated industries.

Capital Markets

Greenstone announces share sale in Gunnison Copper Corp.

Greenstone Resources II LP, registered in Guernsey, has announced a sale of its shares in Gunnison Copper Corp. The announcement follows earlier news releases in February 2026. The offering is restricted from distribution into the United States.

Why it matters

Analysis: A secondary sell-down by a private equity-backed resources fund signals a monetisation cycle in copper, a metal whose price trajectory is closely tied to energy transition demand. The US distribution restriction points to regulatory structuring considerations that will be relevant to any cross-border investor base.

Infrastructure

Port of Vancouver and GCT sign MOU to advance Roberts Bank Terminal 2

The Vancouver Fraser Port Authority and GCT Global Container Terminals have signed a Memorandum of Understanding to explore a partnership advancing Roberts Bank Terminal 2 at the Port of Vancouver. The MOU was reached with support from the Major Projects Office. Roberts Bank Terminal 2 is one of Canada's largest proposed port infrastructure projects.

Why it matters

Analysis: Roberts Bank Terminal 2 would materially increase Canada's container capacity on the Pacific, with direct implications for supply chain resilience and trade flows through British Columbia. An MOU with a major terminal operator signals the project is advancing from planning into structured commercial development.

Aviation / Labour

Porter Airlines customer service workers at Pearson certified with Steelworkers union

The United Steelworkers union has certified 146 Porter Airlines customer service workers at Toronto Pearson International Airport. Workers cited concerns over wages, hours, and benefits. The certification opens the door to collective bargaining at one of Canada's fastest-growing carriers.

Why it matters

Analysis: Certification at Pearson, Porter's largest hub, introduces a new layer of labour cost and negotiating complexity for an airline that has been aggressively expanding its network. If wage and benefit demands prove significant, the pressure on Porter's unit economics will be felt at a time when aviation margins are already thin.

Corporate Governance

Fermi co-founder Neugebauer, ousted as CEO, pushes for company sale

Toby Neugebauer, co-founder of AI power company Fermi Inc., was removed as chief executive late last week. He is now calling for the company to be sold. Fermi operates in the prospective AI power infrastructure sector.

Why it matters

Analysis: A founder-CEO removal followed immediately by a public push for a sale is a classic trigger for a contested M&A process. Prospective buyers and advisers will need to assess whether the board and Neugebauer are aligned, and whether any sale mandate is credible without board support.
