I think it's nailed on Sidara formally bid and secure the deal
If Sidara already completed due diligence just six months ago and walked away due to external factors like geopolitical risks and market uncertainty — not internal issues with Wood Group — it suggests that any major red flags with the business itself would’ve already been identified.
For them to return so soon likely means that whatever caused them to step back last time wasn’t related to Wood Group’s fundamentals. It could also indicate that either those external risks have eased or they’ve reconsidered their strategic priorities.
It would be pretty unusual for a company to re-engage this quickly if they’d uncovered serious internal problems. Their return suggests they may still see strong value in the deal — possibly at a better price — and could be positioning themselves for a formal bid.
Sidara re-entered, immediately post 6 month feeeze, in full knowledge of what's in the books. They are not going to walk away without making a decent final offer
