HEG Advanced Materials Limited makes a corporate announcement

For the ₹1,606 crore anode expansion, HEG has disclosed the funding sources directionally but not the exact split. Management said the project, to be implemented over two to three years, would be funded through internal accruals plus loans, with spending phased as the project progresses; it did not specify how much would come from each source ^[1].

The project is planned in two stages—20,000 MT by June 2027 and the remaining 24,000 MT by March 2029 ^[2]. Accordingly, the balance-sheet impact should be progressive rather than an immediate ₹1,606 crore increase in debt:

• Internal accruals will fund part of the outlay and limit the amount of borrowing required.
• External debt will increase gross debt as construction payments are made, causing debt-to-equity to rise during the build-out.
• As the company has not disclosed the rupee debt commitment, drawdown schedule, or equity/accrual contribution for this specific ₹1,606 crore expansion, its peak and ending debt-to-equity ratios cannot be calculated from the disclosed information.

Important distinction: the reported 65:35 debt-to-equity mix relates to TACC’s separate 20,000 TPA synthetic graphite project, estimated at ₹1,892.7 crore—not explicitly to the ₹1,606 crore expansion ^[3]. That structure implies project-level debt-to-equity of approximately 1.86x, calculated as 65 ÷ 35, but it should not be applied to the ₹1,606 crore project without management confirmation.

Thus, the correct conclusion is phased leverage increase, but no company-disclosed projected consolidated debt-to-equity path for the ₹1,606 crore project. The ultimate ratio will depend on the eventual debt drawdown and the pace of internal cash generation.

The plan is front-loaded: commission 20,000 MT in June 2027 (Q1 FY28), then add 24,000 MT by March 2029, taking total anode capacity to 44,000 MT. Capex deployment is similarly concentrated in FY27 and the first quarter of FY28.

Anode commissioning schedule

Management had earlier indicated that the 20,000 MT facility would operate at approximately 40% utilisation in FY28 and reach full-year contribution in FY29 ^[6]. This is a ramp-up assumption, not a commissioning date.

Capex deployment milestones

Key interpretation: the disclosed plan implies that the original 20,000 MT facility should be substantially funded by the end of FY27, with only the final payment tranche extending into Q1 FY28. The larger uncertainty is not Phase I funding but the precise FY29 deployment for the additional 24,000 MT. An earlier management discussion referred to a smaller subsequent 10,000 MT expansion costing approximately ₹800 Cr and targeted for 2029 ^[6], while the later investor presentation describes the expanded roadmap as 24,000 MT, so the two disclosures are not perfectly aligned.

HEG’s initial 20,000 TPA anode facility is meaningful but not large enough to satisfy the domestic market on its own. Against the company’s estimate of 120,000–140,000 TPA Indian anode demand by 2030, Phase I would represent roughly 14.3%–16.7% of that market on a capacity-to-demand basis. The planned expansion to 44,000 TPA would equate to approximately 31.4%–36.7%, while the longer-term 60,000 TPA FY32 target would equal roughly 42.9%–50.0% of the cited 2030 demand benchmark. These are mechanical comparisons, not expected market shares, because HEG also intends to serve export markets and capacity utilisation may ramp gradually. ^{[9] [5] [10]}

Domestic supply landscape

The opportunity is primarily an import-substitution and non-China sourcing opportunity, rather than entry into a well-supplied domestic market:

• Domestic anode production is described as limited, with India continuing to rely mainly on imports, particularly from China. The announced domestic battery-capacity pipeline includes 50 GWh under the ACC/PLI framework and a further 178 GWh announced by multiple players; this translates to an estimated 178,000 TPA of anode demand using the cited one-tonne-per-MWh assumption. ^[11]
• HEG separately cites Indian cell-manufacturer plans of 120–140 GWh by 2030, translating into 130–150 kTPA of anode demand. ^[12]
• The company’s broader market case is that synthetic graphite dominates anode demand and that supply outside China is likely to tighten as localisation, trade restrictions and supply-chain diversification accelerate. ^[9]

A precise current domestic anode-output figure could not be confirmed from the cited material. Therefore, the 20,000 TPA Phase I should be viewed as a sizeable first domestic-scale platform, but not evidence that HEG will control the domestic supply pool.

HEG’s stated off-take strategy

Management’s approach is to secure customers through technical qualification first, followed by long-term commercial agreements:

1. Use the 200 TPA demonstration plant for qualification. The demo facility uses the same process flow and technology as the commercial plant. Material has been supplied to more than 20 global cell OEMs, and management said most were satisfied with the specifications and quality. Discussions on long-term off-take terms were then initiated. ^[10]

2. Engage directly with cell makers and automotive-linked customers. HEG says its team is in contact with almost every major cell OEM, including companies supplying marquee EV OEMs and battery makers serving EV, ESS and hybrid applications. Customers representing potential off-take of approximately 30,000 MT were described as being in advanced discussions—above the 20,000 TPA Phase I capacity. ^[13]

3. Build a broader multi-customer pipeline. The Q2 FY27 presentation refers to MOUs or agreements covering more than 100,000 MT being under discussion, with domestic customer discussions linked to more than 100 GWh of planned cell capacity. Commercial validation was expected to begin in early 2027. ^[14]

4. Prioritise higher-value EV demand while retaining ESS as an initial market. Management’s stated target mix is approximately 70% EV and 30% ESS, reflecting its view that EV customers offer higher realisations, while ESS is likely to be the faster-growing near-term domestic segment. ^[15]

Analytical read: the off-take strategy is credible in process—pilot validation, OEM qualification, direct engagement and staged commercialisation—but the evidence currently indicates advanced discussions and prospective commitments, not fully secured binding contracts. Signed volume, contract tenor, pricing formula and take-or-pay provisions could not be confirmed from the cited materials.
