BHI Company Analysis — Verifying a Hidden Beneficiary of the LNG and Nuclear Boom Through DART
Whenever talk turns to the global boom in LNG combined-cycle and nuclear power investment, BHI is a name that comes up often. Analysts have even used the phrase “record-high results in 2026,” so I wanted to check directly through DART filings whether the actual numbers back that up.
BHI is a power-equipment specialist that localized HRSG (heat recovery steam generators), the core equipment in gas combined-cycle power plants, as well as nuclear balance-of-plant (BOP) equipment. This piece tries to answer three questions. First, how solid is the 2024-2025 earnings turnaround? Second, why did operating profit rise sharply in H1 2026 while net income actually fell? Third, is the debt ratio, which is rising alongside the growing order backlog, a normal growing pain or a real concern? This is based on DART’s 2026 semiannual report and the 2023-2025 annual reports.

BHI Business Structure — Two Growth Engines: World-Leading HRSG and the Nuclear Boom
BHI’s core business is HRSG (heat recovery steam generators), an essential piece of equipment in gas combined-cycle power plants that captures heat from gas turbine exhaust to generate additional steam for power generation. The company has held the No.1 global market share in this segment for two consecutive years. HRSG revenue in Q1 2026 surged 93.3% year over year to KRW 190.7B, driving overall earnings growth, and HRSG is expected to account for as much as 73% of total revenue in 2026. Alongside this, BHI also runs a localized nuclear BOP business and has recently been expanding into the U.S. nuclear supply chain and the SMR (small modular reactor) space. Participation in the 2026 Korea Nuclear Annual Conference and a B2B meeting with U.S.-based Fermi are part of an ongoing push into the North American nuclear market — putting the company on two global power-equipment investment cycles, LNG and nuclear, at the same time.
The order momentum is equally clear. New orders rose from KRW 1.48T in 2024 to KRW 1.8T in 2025 (of which KRW 1.6T was overseas), with 2026 guidance at KRW 2T. As a result, the order backlog reached KRW 2.4T, up 28.9% year over year, giving the company solid revenue visibility for the next several years. Additional Middle East LNG HRSG orders and a large HRSG supply contract for a Japanese LNG combined-cycle plant also point to growing geographic diversification across the Middle East, Asia, and North America — which we view as a positive.
BHI’s 3-Year Financial Trend — Operating Margin Climbs from 4.1% to 14.0%, a Clear Turnaround
| Metric | 2023 | 2024 | 2025 | H1 2026 |
|---|---|---|---|---|
| Revenue | KRW 367.4B | KRW 404.7B | KRW 774.1B | KRW 577.1B |
| Operating Profit | KRW 15.1B | KRW 21.9B | KRW 75.5B | KRW 80.8B |
| Operating Margin | 4.1% | 5.4% | 9.8% | 14.0% |
| Net Income (Controlling) | KRW 7.5B | KRW 19.6B | KRW 65.2B | KRW 25.4B |
| YoY Operating Profit | — | +45.3% | +244.3% | +146.2% |
| Debt-to-Equity Ratio | 477.3% | 350.7% | 367.6% | 444.6% |
The operating margin, which was 4.1% in 2023, climbed steadily to 5.4% in 2024, 9.8% in 2025, and 14.0% by H1 2026. Revenue grew 91.3% from KRW 404.7B in 2024 to KRW 774.1B in 2025, and H1 2026 revenue already reached KRW 577.1B, up 89.5% year over year. Following a record Q1 (revenue KRW 280.8B, operating profit KRW 35.3B, YoY +183.9%), Q2 set another quarterly record (revenue KRW 296.3B, operating profit KRW 45.5B, YoY +123.1%) — a sign, in our view, that this growth is not a one-off. That said, net income (controlling) actually fell 34.1% year over year to KRW 25.4B in H1 2026 (from KRW 38.6B a year earlier), driven not by weaker operations but by roughly KRW 34.3B in valuation and trading losses on FX forwards and swaps in Q1 alone, caused by a rising exchange rate. Operational strength is clearly improving, but the net-income volatility that comes from FX-hedging derivatives needs to be viewed as a separate factor.
BHI Balance Sheet Deep Dive — What a 444.6% Debt Ratio Means Amid an Order Boom
| Item | End of 2025 | End of H1 2026 | Change |
|---|---|---|---|
| Total Assets | KRW 830.8B | KRW 1,100.0B | +32.4% |
| Total Equity | KRW 177.6B | KRW 202.0B | +13.7% |
| Total Liabilities | KRW 653.1B | KRW 898.0B | +37.5% |
| Debt-to-Equity Ratio | 367.6% | 444.6% | +77.0pp |
| Cash & Equivalents | KRW 60.0B | KRW 125.4B | +109.2% |
| Inventory | KRW 9.0B | KRW 14.8B | +64.6% |
| Operating Cash Flow (H1 2026) | — | KRW 67.2B | +107.0% vs. KRW 32.4B a year earlier |
| CAPEX (property & equipment acquired, H1 2026) | — | KRW 13.0B | Continued investment in production capacity |
The debt-to-equity ratio rising from 350.7% at end-2024 to 444.6% at the end of H1 2026 looks concerning at first glance, but on closer inspection it looks more like a natural consequence of the order boom than a red flag. The largest components of the liabilities are not interest-bearing borrowings but “excess billings over construction in progress” (KRW 384.1B at the end of H1 2026) and “trade and other payables” (KRW 260.6B) — line items typical of how large EPC/plant companies account for project progress. As the order backlog has grown to KRW 2.4T, the related working capital has naturally grown alongside it. What stands out more, in our view, is that cash and equivalents jumped 109.2% in a single half and operating cash flow rose to KRW 67.2B, more than double (+107.0%) the year-earlier level — evidence that the order boom is translating into real cash-flow improvement. Still, with the debt ratio itself above 400%, how the company manages its financial burden amid interest-rate or raw-material price swings is something worth continuing to monitor.
BHI CAPEX & New Business — Expansion into the U.S. Nuclear Supply Chain and SMR
BHI invested KRW 13.0B in property and equipment in H1 2026 alone, continuing to expand HRSG production capacity. More notable than the capex, though, is the company’s business expansion. BHI is making tangible progress toward entering the U.S. nuclear supply chain, including a B2B meeting with U.S. nuclear startup Fermi, as it accelerates its push into the North American nuclear market. The company also took part in the 2026 Korea Nuclear Annual Conference to explore expanded global nuclear market cooperation, signaling a push not just into large-scale nuclear but also into the emerging SMR (small modular reactor) commercialization wave. With the U.S. administration’s nuclear expansion roadmap and SMR commercialization efforts converging, some see potential for BHI to grow simultaneously across both large-scale and next-generation nuclear power. That said, these new-business efforts are still at an early stage without confirmed orders or revenue, so it’s worth tracking whether they translate into actual contracts.
BHI Earnings Swing Analysis — Why Operating Profit Surged While Net Income Fell
| Cause | Detail | Temporary / Structural |
|---|---|---|
| ① HRSG order boom driving operating profit higher | HRSG revenue surged 93.3% in Q1, lifting both revenue and operating profit; an order backlog of KRW 2.4T (+28.9%) secures growth visibility | Structural (tied to the global LNG/nuclear investment cycle) |
| ② Derivative valuation losses from a rising exchange rate | FX-hedging forwards and swaps generated roughly KRW 34.3B in valuation and trading losses in Q1 2026 alone, sharply worsening non-operating income and driving net income lower | Temporary (tied to FX moves; can reverse if the exchange rate retraces) |
| ③ Rising debt ratio | Growing orders expanded excess billings and trade payables, pushing the debt ratio from 367.6% to 444.6%; operating cash flow, however, actually improved | Structural, but viewed as normal expansion tied to the order boom |
✅ Three Investment Points
① Dual benefit from world-leading HRSG and the nuclear boom
With the No.1 global HRSG market share for two years running and an order backlog up 28.9% to KRW 2.4T, the company is riding both the LNG and nuclear investment cycles at once.
② A clear margin-improvement trend
The operating margin has climbed steadily from 4.1% in 2023 to 14.0% in H1 2026, confirming both economies of scale and genuine profitability gains.
③ Emerging entry into the U.S. nuclear and SMR markets
Progress toward the U.S. nuclear supply chain and cooperation with partners like Fermi give the company additional growth potential across both large-scale nuclear and SMR.
⚠️ Three Risks
① Debt ratio has crossed into the 400% range
The debt-to-equity ratio has risen from 350.7% at end-2024 to 444.6% at the end of H1 2026 — an absolute level high enough that ongoing financial-burden management deserves continued monitoring.
② Net income volatility driven by derivatives
Quarterly net income can swing significantly with FX-hedging derivative valuation gains or losses, so judging performance on operating profit alone risks being misleading.
③ New businesses remain at an early stage
The U.S. nuclear and SMR initiatives are still at the cooperation-discussion stage without confirmed orders or revenue, creating risk that expectations get priced into the stock ahead of actual results.
My Investment Take on BHI
Looking purely at operating strength, this is one of the clearest turnaround stories of the past three years. The operating margin has climbed steadily from 4.1% to 14.0%, and the order backlog of KRW 2.4T secures revenue visibility for several years ahead. With the No.1 position in HRSG combined with expansion into nuclear and SMR, we see potential for this to become more than a simple earnings recovery — a genuinely structural growth story.
My call is overweight, approached with two conditions in mind. First, having confirmed that the H1 2026 decline in net income was not caused by weaker operations but by a temporary factor — FX-hedging derivative valuation losses — I would not mistake this for a sign of deteriorating fundamentals. Second, while the debt ratio crossing above 400% looks like a normal consequence of the order boom, I would revisit this view if that structure becomes prolonged or if the improving trend in operating cash flow reverses.
Triggers that would change my view: ① If cooperation on U.S. nuclear and SMR projects materializes into actual orders or contracts, I would add further to the position. ② Conversely, if the debt ratio keeps climbing while operating cash flow deteriorates again, I would hold off on adding and shift to a sidelines stance.
