Digital Holdings (2389 JP): SilverCape’s Hostile Competing Bid Is Met with Countermeasures
- The Digital Holdings Inc (2389 JP) Board has responded to SilverCape’s hostile offer by proposing countermeasures ostensibly to protect the interests of minorities.
- The precedent Makino countermeasures against Nidec’s hostile offer were intended to buy time for a higher white-knight offer. In this case, it is being done to facilitate a lower offer.
- The countermeasures will severely dent SilverCape’s chances of succeeding. Hakuhodo Dy Holdings (2433 JP)’s irrevocables and insiders should be sufficient to pass the shareholder vote to implement the countermeasures.
AUB Group (AUB AU): EQT’s NBIO at A$45.00
- In response to an AFR article, AUB Group Limited (AUB AU) confirmed that on 26 September, it received a non-binding proposal from EQT (EQT SS) at A$45.00.
- While the offer represents an all-time high, it is arguably light compared to precedent transactions and peer multiples. EQT’s history of unsuccessful ASX tilts warrants some caution.
- The Board has granted a six-week exclusive due diligence period, which ends on 20 November. The shareholder structure reduces the vote risk.

- Korea’s export model is fading, but a $6T Korea–Japan bloc plus CPTPP buzz offers a fresh policy‑momentum catalyst, with AI/data angles luring incremental global flows.
- Korea–Japan cooperation isn’t a real bloc yet, but it trades like a policy theme—Chey’s 3PRO push makes it a headline‑driven short‑term play ripe for desks.
