The Mill Liner That Wants To Grind Mountains. And Buy Molycop Doing It.

Welcome to the Grindstone Wars: When Mill Liners Attack

Tega Industries manufactures polymer-based mill liners. No, not the beer. Mill liners are rubber-ish consumable wear components that line the insides of grinding mills used in mineral processing. Copper mines. Gold mines. Anything you dig out of the earth that needs crushing and grinding — Tega’s products go into the machine doing the crushing.

Since 1976, they’ve quietly dominated this niche. Second-largest globally by revenue in polymer-based mill liners. 75% of orders are repeat orders (sticky, recurring, beautiful). Global footprint spanning 70+ countries. Only 10-15% of revenue comes from India — this is a global consumables business with near-perfect pricing power because switching costs are non-zero and customers care about uptime more than price.

Then in November 2025, they got ambitious. Tega announced they’d acquire Molycop — the world’s largest manufacturer of grinding media (those steel balls that do the actual grinding inside mills) — for $1.455 billion enterprise value. Enterprise value. With debt inside. This wasn’t a small bolt-on. This was “we’re going to become the global comminution circuit leader” energy.

The deal structure: Tega owns 84% (~$359 million equity stake), Apollo Funds owns 16% (and is infusing $270 million in perpetual preference shares to optimize Molycop’s capital structure). Financing: ₹1,713 crore raised via preferential share issue in November 2025 at ₹1,994 per share. Plus ₹1,500 crore debt. Plus ₹3,517 crore in OCRPs (Optionally Convertible Redeemable Preference Shares). Plus internal accruals. Deal closing: expected by March 31, 2026, pending antitrust approvals in 12 jurisdictions.

So now Tega is a company in transition: smaller, focused business (the mills and consumables) plus a pending mega-acquisition that’s already diluting EPS because every quarter brings fresh “transaction costs.” Q3 was ugly. But management keeps saying the underlying business is fine. Let’s figure out if they’re right or just really good at spin.

Rubber Liners. Steel Balls. Mining Suffering. Tega Profits.

The business splits into two segments: Consumables (84% of revenue pre-acquisition) and Equipment (16%).

Consumables: Mill liners (the rubber part that prevents ore from sticking to the mill), wear-resistant components, conveyor components, screens, trommels, hydrocyclones. All of these are critical-to-operate items. A mine’s grinding mill breaks down because the liner wears out, and the mine loses millions per hour of downtime. So they buy Tega’s premium products at premium prices. 75% of Tega’s revenue comes from repeat orders because once you put Tega in your mill, switching is pain. The customer knows the fit, the performance, the exact delivery timeline. Why risk a different supplier?

Equipment: Tega acquired Tega McNally Minerals Ltd (TMML) in Feb 2023, which manufactures grinding mills, screens, trommels, material handling, and processing equipment. Global market size for equipment: ~$28 billion annually. Tega’s trying to integrate equipment sales with consumables — sell the mill + the liners that go into it + the ongoing spares. Lock in the customer for life.

Geography: 85-90% of revenue from exports. Gold + copper mining drives 75-77% of demand. When copper and gold prices go up, more marginal mines reactivate, ore throughput increases, and Tega ships more liners. Raw material exposure: ~50% of base chemical inputs are imported (though management says they hedge and have local sourcing).

Q3 Results: The Plot Thickens (Very Badly)

Result Type: Quarterly Results  |  Q3 FY26 EPS: ₹2.62  |  Annualised EPS (Q3×4): ₹10.48  |  9M FY26 Revenue: ₹1,210.3 Cr

The Tale of Two Businesses (And Only One Is Growing)

Consumables (84% of 9M revenue, ₹1,017 cr): Growth is soft at ~6% YoY, but management frames this as a timing issue, not a market issue. Quote from MD: “Sustainable spares (repeat orders) is back very strong, but new customer conversions experienced a lag.” Translation: you’ve got repeat business rolling in, but converting *new* customers has stalled. CFO added: “There is no market loss per se — only about a volume shift from this quarter to subsequent quarters.” So orders are delayed by “a quarter or two,” not cancelled. The company guided full-year consumables growth at ~8% (vs earlier higher aspirations). Gross margin on consumables is typically 57-60%, with EBITDA margin of 22-23%. They pass on raw material inflation via contractual mechanisms with a quarter lag.

Equipment (16% of 9M revenue, ₹183 cr): This is the growth engine. 9M equipment revenue: ₹182.6 cr, +34% YoY. But Q3 equipment revenue was ₹47.5 cr vs ₹54.7 cr YoY (decline of -13% QoQ). Why? Project shipment timing. Equipment deals are lumpy by nature. Q3 was weak, but management says the backlog is “strong” and Q3 spillover will ship in Q4. Gross margin on equipment: 40-45%. EBITDA margin: 13-14% (excluding unusual items, but caveated for “quarter-to-quarter lumpiness”). Equipment is now PBT-positive YTD vs marginally negative last year — so progress on profitability.

What’s This Mining Play Worth? (Spoiler: Not Clear)

$1.455 Billion Bet. 84% Stake. March 31 Closing Target. Antitrust in 12 Jurisdictions.

Assets Growing. Debt Surging. Equity Getting Diluted.

Operating CF Is Fine. But Transaction Costs Are Eating Everything.

ROCE Is Mediocre. ROE Is Weak. P/E Is Stratospheric.

Revenue Growing. But Margins Crumbling Like Cookies in Milk.

Revenue grew 13.8% CAGR over 3 years, but PAT grew only 1.8% CAGR. Translation: top-line growth was eaten by depreciation (TMML acquisition), interest (debt service), and now acquisition-related charges. This is why EPS growth has been anaemic. Once Molycop synergies kick in (if they do), the leverage will flip in your favour.

Tega vs. The Competition (Mostly Losing)

Tega’s P/E of 66.6x is pricey but not the worst in this peer set. Aditya Infotech is at 74.7x. But Aditya has 20.9% ROE vs Tega’s 15.5%. Jyoti CNC has a 24.4% ROCE vs Tega’s 17.8%. The peers earning higher returns trade at similar or lower multiples. That’s the red flag.

Promoters Sold. Then Bought Back. Now at 67.27%.

CRISIL Put Them On Watch. Here’s Why That Matters.

The Comminution Circuit Wars (And Why Tega Just Went All-In)

Geographic breakdown: Tega operates in 70+ countries. US (~25-30% of sales), Australia (~15-20%), LATAM (~20-25%), Europe (~15%), Rest of World (~15-20%). Molycop has strengths in US, Australia, and LATAM. Post-deal, you’ll have geographic redundancy but also geographic diversification. That’s a net positive for risk management.
