Four ASX shares that are not letting that hold them back today are listed below. Here's why they are climbing:

Mac Copper CDI (ASX: MAC)

The Mac Copper share price is up 20% to $18.64. This has been driven by news that the copper miner has accepted a takeover offer. Harmony Gold Mining Company Limited (NYSE: HMY) tabled an offer of US$12.25 (A$18.931) cash per share. This implies a fully diluted equity value of ~US$1.03 billion (~A$1.60 billion) and represents a 20.7% premium to its last closing price. The company said: "The MAC board unanimously recommends that MAC shareholders vote in favour of the Scheme, in the absence of a Superior Proposal." Several major shareholders with a combined holding of 20.1% have expressed their support for the deal.

Pro Medicus Ltd (ASX: PME)

The Pro Medicus share price is up almost 3% to $286.12. This follows a strong rise in the tech sector on Wednesday after a great night of trade on the tech-focused Nasdaq index. It isn't just Pro Medicus that is rising today. The S&P/ASX All Technology Index is up 1.5% at the time of writing.

Web Travel Group Ltd (ASX: WEB)

The Web Travel share price is up almost 13% to $5.27. Investors have been buying this business to business travel company's shares following the release of its full year results. Web Travel posted a 22% increase in total transaction value (TTV) with strong growth in all regions. And while its TTV margins weakened in FY 2025, they have now stabilised. Web Travel managing director, John Guscic, also revealed that FY 2026 has started strongly. He said: "We have had an exceptional start to FY26 trading with TTV up 37% and Bookings up 29% compared to the same period last year. We are targeting record EBITDA in FY26 and remain committed to delivering $10 billion TTV in FY30 at circa 50% EBITDA margins."

Yancoal Australia Ltd (ASX: YAL)

The Yancoal share price is up 2.5% to $5.37. This follows the release of the coal miner's annual general meeting update this morning. Commenting on the year ahead, management said: "So far in 2025, international coal indices have been under pressure. Fortunately, our large-scale, low-cost mines see us well positioned to ride out this downturn in the coal price cycle. Yancoal is in strong financial shape with about $1.8 billion of cash and no interest-bearing debt. We look forward to delivering on our 2025 operational guidance and continue to look for value adding opportunities to carry the company forward."

The ASX small-cap copper miner closed at $15.51 per share yesterday.

Meantime, ASX All Ords large-cap copper share Sandfire Resources Ltd (ASX: SFR) is the fastest riser of the S&P/ASX 200 Index (ASX: XJO) today.

Let's investigate.

Why are MAC Copper shares frozen?

MAC Copper shares are in a trading halt after a request by the company.

In a letter to the ASX, MAC Copper said it wanted a trading freeze on its shares pending an upcoming announcement.

The announcement relates to "a potential control transaction".

MAC Copper shares will remain frozen until the earlier of either the release of the announcement or the market open on Thursday.

MAC Copper changed its name from Metals Acquisition Limited about six months ago.

The company's flagship asset is its 100%-owned CSA Copper Mine near Cobar in NSW, which it acquired from Glencore PLC in June 2023.

CSA is one of Australia's highest-grade copper mines with a targeted annual output of more than 50kt by 2026.

Largest ASX All Ords copper share leads market today

ASX All Ords large-cap copper share Sandfire Resources is leading the market today, buoyed by a stronger copper price.

The Sandfire Resources share price is up 4.81% to $11.55 at the time of writing.

This makes it the fastest riser of the ASX 200 Index today.

The ASX 200 is up 0.17% while the S&P/ASX All Ordinaries Index (ASX: XAO) is up 0.16%.

The copper price is currently trading at US$4.8203 per pound, up 0.33%. The copper price rose by almost 4% in yesterday's session.

The red metal is up by more than 20% in the year to date amid growing global demand due to the green energy transition.

The global shift towards renewable energy, electric vehicles (EVs), and digital infrastructure has significantly increased copper demand.

Copper is essential for electrical energy systems such as EVs, wind turbines, solar energy systems, and data centres.

IG Chief Market Analyst, Chris Beauchamp, says copper demand could grow by 50% by 2040, requiring new mines to raise global production and prevent severe shortages.

Trading Economics analysts explained yesterday's near-4% rise:

The rally was supported by a weakening US dollar, which continued to slide amid investor concerns over President Donald Trump's unpredictable trade policies that have dented confidence in US assets.

The analysts said copper supply appears "ample" for the moment, particularly after stronger output from mines in South America.

Small-cap copper stock offers major upside: broker
