Why Monash IVF, NAB, Viva Energy, and Worley shares are falling today

The S&P/ASX 200 Index (ASX: XJO) is on course to start the week with a small decline. At the time of writing, the benchmark index is down slightly to 8,942.4 points.

Four ASX shares that are falling more than most today are listed below. Here’s why they are dropping:

Monash IVF Group Ltd (ASX: MVF)

The Monash IVF share price is down 8% to 70.5 cents. Investors have been selling this fertility treatment company’s shares after it rejected a takeover offer from a consortium that includes Washington H. Soul Pattinson and Co Ltd (ASX: SOL). The company’s chair, Richard Davis, said: “The Board, in consultation with its advisers, has formed the view that the revised Proposal in its current form undervalues the Company. The Board is supportive of Dr Victoria Atkinson and looks forward to the execution of her strategy to bring stability and growth to Monash IVF.” However, Monash IVF revealed that it “remains open to discussions regarding a change of control transaction at a higher valuation.”

National Australia Bank Ltd (ASX: NAB)

The NAB share price is down 3% to $41.30. This morning, the banking giant advised that it has reviewed its credit provisioning and capital settings to better reflect the risks in the market caused by the conflict in the Middle East. NAB expects first-half credit impairment charges to be $706 million. This includes “$201 million increase in Forward Looking Adjustments (FLAs) for potential stress which may emerge in sectors more likely to be impacted by fuel supply and cost issues related to the Middle East conflict.”

Viva Energy Group Ltd (ASX: VEA)

The Viva Energy share price is down almost 7% to $2.36 after returning from a trading halt. This morning, the fuel retailer released an update on last week’s fire at its Geelong refinery. Viva Energy advised that in the near-term, the refinery is expected to run diesel and jet fuel production at around 80% capacity, while petrol output is closer to 60%. The good news is that management expects production to recover to 90% capacity over the coming weeks.

Worley Ltd (ASX: WOR)

The Worley share price is down 3.5% to $11.40. This follows the release of a trading update this morning. The global professional services company revealed that it expects the ongoing Middle East conflict to have a negative impact on its FY 2026 earnings, with underlying EBITA expected to be reduced by between $30 million and $40 million. In light of this, Worley has indicated that it is now unlikely to achieve growth in underlying EBITA in FY 2026.
