Risks

Six risks to manage, across four of the five suppliers.

Exhibit 1

Six risks to manage before award.

Each risk and the suppliers it affects

	Risk	Affects
1	Kaynes cut FY26 revenue guidance after a railway order deferral; Q1 FY27 net profit fell.^48–49	Kaynes Technology India
2	Vasantha shows no certificate PDF or registry entry; an older listing cites ISO 9001:2008 by KEMA.^{2, 46}	Vasantha
3	Cubix states 400+ employees; Tracxn reports 32. Real capacity is unclear.^8–9	Cubix
4	Vasantha: no lawsuits, closures or parent company were found in the pages read.²	Vasantha
5	Cubix: older company text says ISO 14001:2004 and OHSAS 18001:2007, which conflicts with the current ISO 14001 and ISO 45001 claims.⁸	Cubix
6	Vinrox: tracxn shows three loans from SIDBI and ICICI Bank totalling over ₹37.9Cr, the largest a ₹30Cr ICICI loan in Mar 2024.⁵⁰	Vinrox

Appendix A · Scoring rules

How the scorecard was scored

Each supplier scores 0–4 per criterion against these rules; p. 8 shows the evidence.

Criterion	Looked at
PCB assembly Counts double.	Processes, Certificates
India location Counts double.	Plant area, Sites in India
Box build	Finishing in-house

Each supplier scores 0–4 per criterion, 4 the best. On a cost or risk criterion, 4 means the least cost or risk.

Weighted total: the two asks in your brief count double; the most a supplier can score is 20.

A cell nothing backs is left unscored, never counted as zero.
