On June 30 HD Hyundai Electric Co., Ltd. (KRX:267260) revised the guidance it had published in January. One number changed.
Orders for FY2026 went from $4,222m to $5,185m, an increase of $963m, or 22.8%. The stated reason for the amendment is a revision of the order forecast following its estimate of full-year performance.
Revenue guidance did not move. It remains ₩4,350bn, which is 6.6% above the ₩4,079.5bn the company delivered in FY2025.
Those two numbers moving at such different speeds is the most useful thing this company has disclosed all year.
Converting the order figure to compare it with revenue guidance requires an exchange rate, and the rate has been moving fast. At ₩1,402.50 to the dollar, the rate used in a Korean filing on August 20, $5,185m is about ₩7,272bn. At ₩1,554.40, the rate this company itself used on July 2, it is about ₩8,060bn.
Against ₩4,350bn of guided revenue, that puts the book-to-bill ratio between 1.67 and 1.85 times.
Worth pausing on the fact that a company guiding orders in dollars and revenue in won hands investors a ratio that changes with the currency. Nothing improper about it, since orders are genuinely won in dollars and reported results are genuinely in won, but anyone quoting a book-to-bill for this company should say which rate they used.
Either way the direction is unambiguous. HD Hyundai Electric expects to take in roughly 70% to 85% more work this year than it expects to deliver. Backlog is compounding.
Look at what else is in the guidance form. Operating income: a dash. Pretax income: a dash. Net income: a dash.
The only two numbers HD Hyundai Electric is willing to forecast are revenue and orders. For a company whose entire investment case rests on an operating margin that went from negative 8.85% in FY2019 to 24.40% in FY2025, declining to forecast that margin is not an oversight.
The honest reading is that management does not believe it controls the variable. Margins at this company are a function of how scarce large power transformers are relative to demand for them, and that is set by the collective capacity decisions of five or six manufacturers worldwide plus the pace of data centre and grid construction. A finance team can forecast revenue from a backlog. It cannot forecast what customers will pay two years out in a shortage that might end.
Investors should read the omission the same way.
If demand were the limit, revenue would grow with orders. It isn't, so the guidance gap is telling you the plants are full.
Large power transformers are made on presses and winding lines that cannot be duplicated quickly, tested in high-voltage bays that are expensive and slow to build, and assembled by workers whose training takes years. Adding capacity is measured in years, and adding qualified capacity for a specific utility or hyperscaler is slower still, because the customer has to certify the plant.
The company is trying. Purchases of property, plant and equipment went from ₩75.4bn in FY2023 to ₩121.6bn in FY2024 to ₩233.5bn in FY2025, and ₩139.9bn in the first half of 2026 alone. Property, plant and equipment on the balance sheet rose from ₩624.3bn at the end of FY2023 to ₩1,065.2bn at June 30, up 70.6%.
Even so, ₩233.5bn of annual capital spending against ₩4.08tn of revenue is 5.7%, and the company is running about four won of revenue for every won of fixed assets. That is an unusually high asset turn for heavy electrical equipment, and it means the existing plant is being worked hard rather than a new one being built.
The consolidated group now includes entities in Alabama, Atlanta and Texas alongside Korea and Europe, so some of the expansion is happening on the customer's side of the tariff line. That matters for a business selling into US utilities and hyperscalers.
A capacity-constrained supplier in a shortage has the strongest position in industry. It fills the plant regardless, chooses which customers to serve, and sets price rather than accepting it. That is precisely how gross margin went from 13.02% in FY2021 to 34.14% in FY2025.
It also means every additional won of demand converts into price rather than volume, which is why orders can rise 23% while revenue rises 7%. The company is not leaving money on the table; it is taking the money as margin instead of as sales.
The problem is symmetrical. When capacity arrives, and the whole industry is building it with exactly these profits, the mechanism reverses. Orders stop being scarce, the queue shortens, and price becomes the variable that gives. A manufacturer with a 25% operating margin in a shortage does not have a 25% margin in balance. This company's own history says what the other side looks like: operating losses in FY2018 and FY2019, and a 0.54% operating margin in FY2021.
At the August 27 close of ₩821,000, up 12.01% that day, across 36,047,135 shares, the market capitalisation is ₩29.59tn against ₩2.26tn of equity. Thirteen times book. That price is not paying for a cycle. It is paying for the shortage to persist.
Capital expenditure, at this company and across the sector. It is the leading indicator that matters, because today's capex is tomorrow's oversupply. HD Hyundai Electric's own spending has tripled in two years and remains modest relative to revenue. The number to watch is whether it keeps rising toward 10% of sales, which would signal the industry is finally building its way out.
The second marker is the FY2026 order figure against the raised $5,185m target, reported with full-year results in January or February. Meeting or beating it means the queue is still lengthening. Missing it, particularly if revenue lands on guidance, would mean customers have stopped rushing to book capacity, and that is the first thing that changes before pricing does.
