Shares of three major ASX-listed companies Domino’s Pizza Enterprises Ltd, Helia Group Ltd,and Qantas Airways Ltd saw significant declines in trading today (2 July 2025), as each faced company-specific setbacks ranging from leadership instability to contract loss and cybersecurity breaches.

Domino’s Pizza Enterprises Ltd (ASX:DMP)

Shares of Domino’s fell by 26% to AUD 14.97 after the company unexpectedly announced the resignation of its CEO and Managing Director, Mark van Dyck. His departure, just eight months into the role, surprised the market and raised concerns about leadership continuity at the multinational pizza chain.

Domino’s stated that van Dyck will step down before the end of the year. In the interim, company chairman Jack Cowin will take over as executive chair starting immediately. The company has begun a global search for a new chief executive to lead the next phase of its operations.

Founded in 1983, Domino’s Pizza Enterprises operates more than 3,800 stores across Australia, New Zealand, Europe, and Asia, making it the largest pizza chain in Australia. The CEO’s abrupt exit follows a challenging period for the company, which has recently been navigating margin pressures, inflationary costs, and changing consumer behaviour.

Helia Group Ltd (ASX:HLI)

Helia Group’s share price tumbled by 24% to AUD 4.16 following news that it had lost a major lender’s mortgage insurance (LMI) contract with ING Bank (Australia). According to the company’s announcement, ING has opted to enter negotiations with another provider for its LMI requirements, which could lead to early termination of the existing agreement.

The current contract between Helia and ING is due to expire on 30 June 2026; however, ING retains the right to terminate the arrangement with three months' notice. Helia disclosed that the business underwritten under this contract accounted for roughly 17% of its 2024 gross written premium (GWP), underlining the significance of the potential loss.

Helia, formerly known as Genworth Mortgage Insurance Australia, provides lenders mortgage insurance solutions across Australia.

Qantas Airways Ltd (ASX:QAN)

Qantas shares declined by over 3% to AUD 10.40 following the disclosure of a cyber security incident affecting millions of its customers. In a statement released this morning, the airline confirmed that it had experienced a significant cyberattack that resulted in the theft of customer data.

An initial investigation revealed that data extracted includes names, dates of birth, email addresses, phone numbers, and frequent flyer numbers. Qantas estimates that up to 6 million customer records stored on the compromised platform may have been affected.

Founded in 1920, Qantas is Australia’s flagship carrier and one of the world’s oldest continuously operating airlines. The company said it is working with cybersecurity experts and regulatory authorities to assess the full impact and strengthen its systems. However, it acknowledged that the breach has the potential to damage customer trust and trigger regulatory scrutiny.
