Domino's Pizza Enterprises Ltd (DMP.AU) saw its shares plummet 7.71% during intraday trading on Wednesday, following the release of key operational data.

The sharp decline came after the company reported that group same-store sales growth (SSSG) for the first eight weeks of the second half of fiscal 2026 was -7.2%. This negative sales performance is a critical metric for investors and indicates potential challenges in the company's core operations during the recent period.

Alongside the weak sales update, the company also reported its first-half financial results, including sales of AUD 40.6 million and adjusted net income of AUD 60.1 million. While the company reaffirmed its full-year guidance and announced an interim dividend of 25.0 AU cents per share, the negative SSSG figure appears to have been the primary driver behind the significant sell-off.
