1. Company overview & snapshot

1.0 The connection — R Mohankumar

• Education: MBA (International Business), XLRI PGCBM, IIM Bangalore SBLP; IICA-certified independent director.
• Current activity: reposting JN’s network and Cummins power-generation posts (Sept 2026), i.e. in growth-and-visibility mode.

• Connection status: 1st-degree.

1.2 What it does & where money comes from

Customers: industries, hospitals, construction, mining, critical facilities.

1.2a Scale, MSME status & trade

Revenue table

Working revenue range: ₹260–300 Cr (FY24–FY25). Confidence: high for FY24, medium for FY25. Matches the brief’s ₹262 Cr.

1.3 Location & footprint

Madurai HQ; 23 branches/outlets across TN and Pondicherry (Chennai, Trichy, Salem, Tirunelveli, Coimbatore, Virudhunagar, Namakkal, Dharmapuri, Ramnad, Sivaganga, Kanyakumari, Vellore and others); south AP since Oct 2018.

1.4 Leadership & CRM map

Decision path: Mohankumar sponsors a referral pilot → Sudhir approves → branch service managers name DG-heavy AMC customers → Stamped pitches the customer’s plant head directly (the customer is the buyer).

1.5 Recent news & timing

• New CEO in Aug 2026: first 100 days, open to new value-adds.
• CRISIL flags rising working capital with scale; Cummins CPCB-IV+ genset transition is reshaping dealer economics.

2. Energy profile

DISCOM / supply: DISCOM: not applicable — no plant (nearest relevant: TANGEDCO / TNPDCL for the industrial genset customers JN services across Tamil Nadu).

2.1 Bill band

• JN’s own offices and workshops: ₹2–5 lakh/month [~] total, not worth a pilot.
• Typical TN industrial genset AMC customer (textile spinning mill, foundry, auto-component plant) on HT supply: ₹30–150 lakh/month [~] grid, plus diesel spend during cuts or peak.

2.2 Generation & fuel

Customers: Cummins DG sets (often 500–2,000 kVA) as backup or peak-shaving; diesel at roughly ₹25–30 per kWh generated [~] vs TANGEDCO HT energy around ₹7–8 per kWh plus demand charges.

2.3 EnMS, PAT, ISO

JN: not applicable. Customers: mixed.

2.4 Likely ₹ leak categories (at customer sites)

DG running beyond grid-restoration windows, DG used for peak shaving when grid MD headroom exists, DG part-load operation (high specific fuel consumption), MD stacking on TANGEDCO meters, PF penalties.

3. Operations, equipment & digital stack

3.1 Process flow

Sales → installation → AMC → breakdown service (4-hr SLA) → spares and lubes.

3.2 Digital stack

Cummins Insite and Inpower diagnostic software used by JN engineers; genset controllers expose run hours, load and fuel data. Stamped could read genset controller data alongside the grid meter (read-only) at customer sites.

3.3 Metering (customer sites)

TANGEDCO HT meter + genset controller; sub-metering often thin. Path B (bill + main meter + genset run logs) works.

4. Stamped Energy fit analysis

4.1 ICP scorecard

4.2 Fit score rationale

3/10. Not a buyer. Channel value depends on whether JN will share customer names and whether Stamped wants a TN wedge now.

4.3 Wedge

The strongest wedge is: a DG-vs-grid rupee report offered as a free value-add to two or three of JN’s heaviest industrial AMC customers, sponsored by Mohankumar, so JN’s service contract looks stronger and Stamped gets warm TN plant intros.

4.4 Objections

• “Less DG running means fewer service hours for us” → AMCs are fixed-fee; optimal loading improves engine life and customer loyalty; Stamped does not sell gensets or service.
• “We’re a dealer, not an energy firm” → no selling required from JN, only introductions.

4.5 Pilot design

One JN customer plant; 60-Day Proof on grid meter + genset logs; success = verified ₹ saving from avoidable DG hours and MD; kill = customer won’t share genset run data.

4.6 Concern scores (JN customer plant)

4.7 Pitch sketches

1. Mohankumar: “A value-add for your AMC customers that costs JN nothing.”
2. Customer plant head: “Which DG hours were avoidable last month, in rupees, verified with evidence.”
3. Sudhir (MD): “Stickier service contracts, no product conflict.”

5. Before you reach out

5.1 Discovery checklist

• How many industrial (vs hospital/commercial) genset AMC customers in TN?
• Which customers run DG most hours (peak shaving vs backup)?
• Does JN already offer any remote genset monitoring (Cummins PowerCommand Cloud)?
• Would JN co-brand or simply introduce?
• Does JN worry that lower DG hours cuts spares/lube revenue?
• Is Sudhir aligned with the new CEO on partnerships?
• Any customers in south AP worth adding?
• What is his mandate for the first year as CEO?

5.2 Do not lead with

• Do not lead with “cut your customers’ DG running”; frame as better loading and value-add
• Don’t pitch JN as a pilot site
• Don’t lead with solar or ESG (his profile mentions ESG; keep it secondary)

5.3 Opening hooks

“Congratulations on the CEO role. Here is a value-add for your genset AMC customers.”

6. Risks, flags, controversies & sources

6.1 Integrity / controversy / regulatory

• Main risk: channel conflict, since less DG running can mean fewer spares and lube sales for JN, so it may refuse to share customer names; also, TN is outside Stamped’s North India focus.
• CRISIL BB/Stable: moderate credit, large working-capital needs (not a concern for a referral relationship).
• Controversies: none found (searched: “JN Machineries” fraud, complaint, NCLT, GST notice; “R Mohankumar” controversy).

6.2 Data quality flags

• Website still lists Atul N Thakur as CEO; LinkedIn lists Mohankumar (Aug 2026). Treat LinkedIn as current.
• Mohankumar email inferred; JN uses jnmpl.com for branch inboxes.
• FY25 revenue derived from EMIS growth figure.
