Beach Energy shares sink on guidance downgrade
Beach Energy shares are the laggard of the pack, down 1.7% at $1.18 apiece.
This follows the release of the ASX 200 energy stock's March quarter update (Q3 FY 2026).
While the company achieved a 7% quarter-on-quarter increase in production to 4.8 million barrels of oil equivalent (MMboe), sales volumes of 5.3 MMboe were down 10% from Q2 FY 2026.
This saw sales revenue decline by 6% from the prior quarter to $419 million.
With some of Beach Energy's operations impacted by inclement weather, the ASX 200 oil and gas company lowered its full-year FY 2026 production guidance to between 19.4 and 20.3 MMboe, down from prior guidance of 19.7 to 22.0 MMboe.
Deep Yellow shares lift on uranium project advancement
Unlike Beach Energy shares, Deep Yellow shares are shaking off the wider market malaise today and charging higher.
Shares in the ASX 200 uranium stock are up 2.6% at the time of writing, changing hands for $1.99 apiece.
This follows the release of Deep Yellow's own third-quarter update.
Deep Yellow is grabbing investor interest after reporting on significant progress across its major projects.
At its Tumas Project, located in Namibia, the uranium miner said that detailed engineering progressed to 68% completion by the end of the quarter, with 91% of the bulk earthworks completed.
"Deep Yellow entered the March 2026 quarter with clear momentum across the business, underpinned by continued advancement of our flagship Tumas development project and a disciplined focus on creating long-term shareholder value," Deep Yellow CEO Greg Field said.
Whitehaven shares lift on improved coal prices
Joining Deep Yellow and Beach Energy shares in the financial headlines today, Whitehaven shares are up 2.5%, trading for $7.90 each.
This outperformance comes after, you guessed it, the release of the ASX 200 coal stock's March quarterly update.
Whitehaven also did not escape impacts from heavy rains, which saw its managed run of mine (ROM) coal production slide 14% quarter on quarter to 9.5 million tonnes.
But the Aussie coal miner is finding support, achieving an 8% quarter-on-quarter increase in its average Queensland coal price to $242 per tonne, while New South Wales coal prices were up 7% from Q2 FY 2026 to $175 per tonne.
Management also reaffirmed Whitehaven's full-year FY 2026 production guidance, with expectations that this will come in towards the top end of guidance.
