Chapter 6
Sum-of-the-Parts
At ¥22.01 on 3 July 2026, TBEA is a ¥112.9bn company — 19x reported and 25x recurring FY2025 earnings, 1.5x the equity attributable to its shareholders. Split that price into its pieces and the surprise is what carries it: the one part with a live market quote, the listed polysilicon stake, is worth only about ¥6bn — roughly 5% of the whole. The other 95% is the grid and coal-and-power engines, and coal, not the grid, is the larger earner.
What ¥22 buys
TBEA earned ¥5.95bn attributable to its shareholders in FY2025, ¥1.161 per share, for a reported P/E near 19x [1]. But ¥1.40bn of that profit was non-recurring, most of it the mark-to-market gain on two listed equity stakes — Huadian New Energy (600930.SH) and CSG Energy (003035.SZ) — revalued at year-end prices [2]. Strip it out and recurring profit was ¥4.55bn, ¥0.8821 per share, lifting the operating multiple to 25x [3]. Return on equity was 8.75% reported, 6.65% on recurring profit [4].

Those are blended multiples on trough-ish earnings: FY2025 profit of ¥5.95bn sits against ¥10.7bn in FY2023 and ¥15.9bn in FY2022 [6]. Whether 19x is cheap or full depends entirely on which parts of the group are doing the earning, and what each is worth on its own.
The parts, by what they earn
TBEA discloses net profit for its four principal subsidiaries — the cleanest way to see where the money is made [7]. The grid franchise — the electrical-equipment group that the investment case leans on (The Grid Franchise) — earned ¥1.69bn on ¥37.1bn of revenue. The coal-and-power engine, Tianchi Energy (Coal and Power), earned twice as much: ¥3.39bn. Polysilicon, Xinte Energy, lost ¥1.33bn (The Polysilicon Engine), and the new-materials arm (XJZH) added ¥0.66bn.

Adjusting for minority interests — TBEA owns all of Tianchi (85.78% directly, the balance through subsidiaries) but only 66.61% of Xinte and 36.81% of the new-materials arm [9] — the coal engine contributes its full ¥3.39bn to TBEA holders, the grid ¥1.7bn, materials only about ¥0.24bn, and polysilicon a roughly ¥0.9bn drag. The "durable core" the report has emphasized is real, but on FY2025 earnings it is the second-largest of the three engines. The largest is a coal-and-power business whose profit has already halved from ¥6.93bn in FY2023 and whose coal-product margin fell from 47.6% to 22.4% (Coal and Power).
The polysilicon option is priced near zero
The polysilicon business is the one piece with an arm's-length mark. Xinte Energy is separately listed in Hong Kong (1799.HK) [10], and the market there values the whole company at roughly HK$10bn — about ¥9bn — trading at close to a quarter of its book value. TBEA's 66.61% share is therefore worth about ¥6bn, or some 5% of TBEA's ¥112.9bn market capitalisation.
Set that against what sits inside TBEA's own accounts: 66.61% of Xinte's ¥37.05bn of net assets is about ¥24.7bn of book value [11]. The market prices the stake at roughly a quarter of that carrying amount. In plain terms, TBEA's shareholders are being asked to pay almost nothing for the polysilicon arm — its ¥82.1bn of consolidated assets, its idle capacity, and any recovery it might deliver.

What the price implies
Take the ¥6bn Xinte stake out of the ¥112.9bn and roughly ¥107bn remains for the grid, coal-and-power, new-materials and the listed-stake portfolio, net of ¥16.6bn of net debt (Cash Conversion). Against combined recurring earnings from those operating engines of about ¥5.3bn, that is close to 20x — a full multiple for a mix in which the biggest single contributor is a coal business already past its own peak, and the grid franchise, though growing, earns a mid-single-digit net margin.
The market's ¥112.9bn rests almost entirely on the grid and coal-and-power engines; the polysilicon arm is priced as a small, cheap option worth about 5% of the total. On through-cycle earnings from the operating core, roughly 20x is full rather than obviously cheap — so the upside case leans on polysilicon inflecting off zero and on the listed-stake value the accounts do not fully show, not on the grid core the label emphasises.
There is a real bull answer to that. FY2025 earnings are depressed: at the FY2022 level, polysilicon alone generated close to ¥19.9bn of gross profit (The Polysilicon Engine), and even a partial normalisation would swamp today's multiple. The Huadian and CSG stakes are worth more than their contribution to reported profit suggests — the ¥1.52bn mark-to-market gain in FY2025 is a hint at scale [15], and Huadian only listed during the year [16]. That is why the four analysts covering the stock carry an average target of ¥32.96, about 50% above the current price.
The bear answer is the arithmetic above: a 25x recurring multiple, a 6.65% recurring return on equity, the largest earner cyclically supported and structurally shrinking, and free cash flow of -¥12.75bn while the polysilicon "option" still consumes capital (Cash Conversion). What would move the read is specific and watchable: a polysilicon price back above Xinte's cash cost, which turns the option live; a coal price that stabilises the ¥3.4bn Tianchi contribution rather than eroding it; and capex rolling off so the core stops leaking cash. Until then, the price pays for the core the company has, not the recovery the label implies.
