The Appen share price is up 11% to $1.25. Investors have been buying the artificial intelligence data services company's shares following the release of an update at its annual general meeting. Appen has reaffirmed its FY 2026 guidance and continues to expect revenue of $270 million to $300 million. Management is also targeting an underlying EBITDA margin before FX of around 5% to 10%. Appen's CEO, Ryan Kolln, said: "We continue to see positive signals on LLM-related growth from both Appen Global and Appen China customers. Tight cost controls remain in place, in keeping with our focus on managing costs in line with the revenue opportunity."
Guzman Y Gomez Ltd (ASX: GYG)
The Guzman Y Gomez share price is up 13% to $20.49. This follows news that the quick service restaurant operator has decided to close its struggling US stores. Guzman Y Gomez's founder and co-CEO, Steven Marks, said: "I have always been confident in the differentiation of our food and guest experience, however this was not translating to an improvement in sales momentum. Having spent the last 3 months in the US, I realised this was going to take significantly more time and capital than we had expected. In assessing the trajectory of the current network, the Board and I have concluded that the business is unlikely to deliver the performance that would justify continued investment of shareholder capital."
Monadelphous Group Ltd (ASX: MND)
The Monadelphous share price is up 2% to $29.97. This morning, this diversified services company announced that it has secured $120 million in new construction and maintenance contracts across the resources and renewable energy sectors. One is from Fortescue Ltd (ASX: FMG) for the battery energy storage system (BESS) construction contract at the Cloudbreak mine.
