Notes

Re-verify 2026-06-04 (self-audit cap-flag): UBTech's named factory partners (BYD, Geely, Foxconn, FAW-Volkswagen, Audi FAW, BAIC, Dongfeng Liuzhou, SF Express) are a MIX of factory pilots/trials and announced partnerships, NOT uniformly verified at-scale production-line deployment; the 'orders exceeding 800M yuan' and 'several hundred units delivered' figures are COMPANY-STATED, not independently audited. Walker S2 mass production + first delivery (Nov 2025) is real, so maturityStage stays commercial, but specific at-scale production-line deployments should not be asserted beyond partner-side confirmation. Note: there is NO 'Walker S3' as of Jun 2026 - the S2 remains UBTech's flagship (a Walker S3 record would be premature/fabricated).
