The reasons are derived automatically from the public data on contracts awarded over the last 12 months (CAIS EOP and TED): value, buyer, number of bids, estimated value, sector and registered office in the Commercial Register. They describe what is visible in the contracts and are not an assessment of the quality or legality of the companies' work.
