Megaport shares surged after major AI-linked contract wins while GrainCorp and Air New Zealand weakened following softer earnings results and rising fuel-cost pressures across key sectors.

Several major ASX-listed companies attracted strong market attention on Thursday as technology, agribusiness and airline sectors reacted to fresh corporate updates.

Within the ASX 200, Megaport Ltd (ASX:MP1) emerged as one of the strongest performers while GrainCorp Ltd (ASX:GNC) and Air New Zealand Ltd (ASX:AIZ) traded sharply lower.

Megaport shares jump on AI infrastructure contracts

Megaport shares surged after the ASX technology company announced three major contracts linked to artificial intelligence infrastructure demand.

The agreements were signed with two United States-based technology providers focused on AI applications.

According to the company:

  • Total contract value reached approximately $254 million
  • Two contracts extend across three years
  • One contract spans two years
  • Around $140 million in new capital investment will be required

Management said the deals position Megaport at the centre of expanding AI infrastructure demand and distributed computing networks.

Chief executive Michael Reid said growing AI deployment is accelerating demand for automated digital infrastructure globally.

For readers following ASX Technology Stocks, AI infrastructure, cloud connectivity and recurring digital services remain major growth themes across the sector.

The strong rally also extended Megaport’s recovery following earlier weakness seen across technology shares during recent months.

GrainCorp falls after softer half-year earnings

GrainCorp shares moved sharply lower after the agribusiness and processing company released weaker half-year results.

The company reported:

  • Underlying EBITDA of $136 million
  • A significant decline from the prior corresponding period
  • Lower grain-handling activity across East Coast Australia
  • Softer operating margins

Management said reduced grower selling activity and oversupply conditions across global grain markets weighed on performance.

The company also pointed to:

  • Lower receivals
  • Multi-year low operating margins
  • Ongoing pressure across agricultural supply chains

Despite the weaker earnings result, GrainCorp reaffirmed full-year FY26 guidance for:

  • Underlying EBITDA between $200 million and $240 million
  • Underlying NPAT between $20 million and $50 million

Within the ASX 200, agricultural and export-focused companies continue responding to commodity pricing, weather conditions and shifting global demand patterns.

For readers following ASX Agriculture Stocks, supply-chain conditions and international commodity trends remain major drivers across the sector.

Air New Zealand pressured by fuel cost surge

Air New Zealand shares also weakened after the airline warned about the financial impact of rising jet fuel prices linked to geopolitical tensions and Middle East conflict developments.

The airline said fuel prices had increased sharply over recent weeks, creating significant pressure on operating costs.

Management now expects to report a FY26 pre-tax loss within a revised guidance range.

The update also attracted attention from market participants monitoring the broader aviation sector, including Qantas Airways Ltd (ASX:QAN).

Fuel costs remain one of the largest operational expenses for airlines globally, making carriers highly sensitive to:

  • Oil price movements
  • Geopolitical instability
  • Supply disruptions
  • Currency fluctuations

Within the ASX 200, transport and aviation businesses continue navigating volatile energy markets alongside broader travel demand trends.

Market themes remain sector-driven

Thursday’s trading activity highlighted the divergence currently shaping Australian equity markets.

Technology companies tied to AI infrastructure and recurring digital revenue continued attracting strong interest, while cyclical sectors linked to commodities and fuel-intensive operations faced renewed pressure.

Broader market sentiment remained cautious as investors monitored:

  • Inflation expectations
  • Commodity pricing
  • Global geopolitical developments
  • Technology sector momentum
  • Interest-rate outlooks

Market participants are expected to continue focusing on:

  • AI-related infrastructure growth
  • Commodity market volatility
  • Energy price movements
  • Corporate earnings updates
  • Global economic conditions

Sector rotation is likely to remain active across the ASX 200 as investors balance growth opportunities against rising operational cost pressures.
