This does not seem very surprising. Big injection of cash, big expansion very quickly and signing some pretty decent riders, but there were rumours of late or missing payments almost from the get-go this year. I suspect some fly-by-night secondary sponsors leaving gaps in costs that lead sponsors were unwilling to bridge, or that they were kind of hoping to wing it on increased winnings until they got to the Spanish mini-season where their sponsors most benefit, and didn't make it.
For the riders, I'm sure the likes of Cordon-Ragot, Nosková and Silvestri can find somewhere even if on the short term, they have plenty of experience around Europe, and Meijering and de Francesco have had good breakout performances this season that should see them safe. The likes of Franz and Maggie Coles-Lyster may have to retreat to the NRC but they should find a home too you'd think. The others will probably be scouting the smaller Spanish and Italian teams for potential I guess as they're either decent enough to fit in on those teams or young enough to be worth a flyer, or both.
