In afternoon trade, the S&P/ASX 200 Index (ASX: XJO) is on course to start the week with a decline. At the time of writing, the benchmark index is down 0.3% to 8,589.2 points.
Four ASX shares that are falling more than most today are listed below. Here's why they are dropping:
ASX Ltd (ASX: ASX)
The ASX share price is down over 2.5% to $56.65. Investors have been selling the stock exchange operator's shares following another damaging event. A number of ASX shares have been suspended from trade today due to an announcement outage. It stated: "ASX has implemented an initial remediation and commenced processing company announcements received since 11:22 AEDT. Earlier announcements remain impacted. We apologise for the disruption from this event and we are seeking to resolve this as soon as possible."
AUB Group Ltd (ASX: AUB)
The AUB Group share price is down almost 17% to $31.02. This follows news that the insurance broker's takeover talks have ended without a deal being reached. EQT and CVC had tabled a non-binding offer of $45.00 per share but have now withdrawn the proposal. AUB's CEO, Michael Emmett, said: "AUB Group continues to deliver robust performance, underpinned by a clear strategy and disciplined execution. The recent due diligence process, while demanding, has reaffirmed our confidence in our improvement initiatives and long-term growth prospects. Now that discussions with the Consortium have ended, our Board and management team are fully focused on advancing our portfolio of organic growth initiatives and acquisition opportunities. We remain confident in AUB Group's forecast FY26 financial performance and see significant opportunities to grow profits in FY27 and beyond."
Dyno Nobel Ltd (ASX: DNL)
The Dyno Nobel share price is down over 3% to $3.30. This has been driven by the commercial explosives company's shares going ex-dividend this morning for its final dividend of FY 2025. Eligible shareholders can now look forward to receiving Dyno Nobel's 9.5 cents per share payout later this month on 16 December.
HMC Capital Ltd (ASX: HMC)
The HMC Capital share price is down 7% to $3.60. This is despite there being no news out of the investment company on Monday. However, it is possible that this has been driven by profit taking from investors after some strong gains in recent weeks. For example, even after today's sizeable decline, HMC Capital's shares are up 24% since the middle of November.
