Chips at Warp Speed, Shipyards at Full Steam: Korea's Q2 Split-Screen

This season's defining feature is a chasm, not a cycle. Memory semiconductors posted median revenue growth of +256.8% year over year while telecom shrank -10.1% — a 267-point spread between the top and bottom industries. In between, shipbuilding (+52.7%) and defence (+47.2%) ran hot, while displays (+0.4%) and auto components (+2.4%) barely moved. The message for an international investor is blunt: Korea is no longer a single macro trade — it is a set of violently divergent micro stories.

Revenue growth by industry (median YoY)

Memory and shipyards delivered the quarter's real torque

SK hynix is the headline: revenue +256.8% and EBITDA +420.9% year over year, a margin expansion that is almost violent. Samsung Electronics, in semiconductors & electronics, matched the revenue surge at +130.0% and still trades at just 8.3x earnings. The memory upcycle is not a whisper — it is a roar, and it is the single biggest reason Korea's aggregate growth looks so lopsided this quarter.

Shipbuilding is the second engine. Hanwha Ocean grew revenue +65.2%, EBITDA +207.7% and net profit +366.6%, while HD Hyundai Heavy Industries added +52.7% revenue and +289.8% net profit. Hanwha Aerospace in defence & aerospace was no slouch either: revenue +47.2%, EBITDA +107.8%, net profit +253.1%. These are not one-off rebounds; they are multi-year order books converting into cash.

Telecom and displays are the quarter's warning lights

KT Corporation is the ugliest print in the dataset: revenue -10.1%, EBITDA -20.3%, net profit -36.0%. That is not a soft patch; it is a structural squeeze. LG Display is the second red flag — revenue essentially flat at +0.4%, EBITDA -17.4% and net profit -146.7%, a swing into loss. Hyundai Motor also deserves a mention: revenue +1.9% but EBITDA -29.6% and net profit -15.9%, a classic case of top-line resilience masking margin erosion.

The plot twist: HMM's revenue surged but profit fell — and that changes the shipping read

HMM grew revenue +29.7% and EBITDA +41.0% year over year, yet net profit fell -12.8%. That is the season's genuine surprise: a container shipper expanding at the top line while bottom-line profit contracts. The divergence between EBITDA and net profit points to higher depreciation, interest or one-off items — a warning that not every revenue beat is created equal. Investors who bought the +29.7% headline without checking the -12.8% net line got a lesson in quality of earnings.

Cheap for the growth: shipbuilders and memory; priced for perfection: component and defence electronics

The value case is clearest in shipbuilding and memory. Hanwha Ocean grows revenue +65.2% yet trades at 8.2x earnings and 11.0x EV/EBITDA; HD Hyundai Heavy Industries at 12.7x P/E and 8.1x EV/EBITDA. SK hynix, growing +256.8%, sits at 5.6x P/E — absurdly cheap if the cycle holds. At the other extreme, Samsung Electro-Mechanics (+24.2% revenue) trades at 80.9x P/E and 37.1x EV/EBITDA, and Hanwha Systems (+45.5% revenue) at 70.6x P/E and 38.1x EV/EBITDA. Those are priced-for-perfection multiples that leave no room for a hiccup.

Income: the banks and KT still pay, but for different reasons

Dividend data is thin in this dataset, but the valuation signals are telling. KT, despite the -10.1% revenue decline, trades at 8.6x P/E and 3.4x EV/EBITDA — the cheapest EV/EBITDA in the sample, suggesting the market is already pricing a deep cut to earnings. Shinhan Financial (+9.4% revenue, +17.1% net profit) at 7.4x P/E and KB Financial (+1.2% revenue, +14.6% net profit) at 8.6x P/E offer steady profit growth at single-digit multiples. For income-focused investors, the banks look like the more reliable payers than the shrinking telecom.

The long view belongs to Hanwha Aerospace, with a three-year revenue CAGR of +55.8%, and Hanwha Ocean at +38.0%. These are not cyclical blips; they are structural re-ratings of Korea's defence and shipbuilding franchises. SK hynix's +29.6% three-year CAGR is impressive but far more cycle-dependent. What to watch next: whether memory pricing holds into the second half, whether shipyard margins keep expanding as newbuild prices reset higher, and whether KT's decline stabilises. The split-screen will persist — but the cheap growth in shipbuilding and memory remains the most compelling risk-reward for a value-focused international investor.
