Energy stocks lifted nearly 1% at midday Tuesday despite oil futures settling at their lowest since February 2021.

Viva Energy Group (ASX:VEA) said it remains on track to deliver first-half earnings before interest, taxes, depreciation, and amortization of AU$270 million to AU$330 million from its non-refining businesses. In the second half of the year, the company plans to deliver AU$30 million in convenience and mobility synergies and AU$50 million in group cost savings.

On the flip side, the healthcare sector struggled, shedding over 1%. The major stock indices on Wall Street fell after US President Donald Trump's latest tariff announcements.

Sigma Healthcare (ASX:SIG) said that growth in its normalized earnings before taxes and interest (EBIT) for the nine months to March 31 was broadly consistent with Chemist Warehouse Group's reported 36% increase in normalized EBIT in the fiscal first half. The company said it incurred transaction costs of AU$42.4 million up to March 31.
