Winhitech

Winhitech is a specialized construction materials company spun off from Wins in September 2011 to manufacture, install, and sell steel structural products, primarily deck plates.

Deck plate is a metal assembly structure used for concrete pouring in building slabs and beams, replacing traditional plywood formwork to shorten construction time and reduce costs.

Its core products include Extra Deck, Void Deck, and Nova Deck, with Extra Deck having obtained certification from the Japan building center, becoming the first in the industry to secure a pathway into the Japanese construction market.

The domestic deck plate market has roughly eight competing manufacturers, and Winhitech is understood to hold approximately third place by market share. The company's business scope extends beyond materials manufacturing and sales into specialized construction and general contracting.

Recently it has expanded contracts with major clients across both industrial and residential segments, including a semiconductor fab construction project ordered by SK Eco Plant and an LH-linked purchased-housing project pursued through its affiliate Incheon Sinpo Complex Development.

Its largest shareholder is S&N Global, which also participated in a recent third-party share placement to maintain control. Because a substantial portion of revenue is tied to domestic construction order volumes and the timing of construction starts, the business model is highly sensitive to the construction cycle.

Winhitech's annual revenue peaked at KRW 153.8bn in 2023 after rising from KRW 116.8bn in 2022, then declined for two straight years to KRW 112.2bn in 2024 and KRW 75.1bn in 2025.

The operating margin also fell sharply from 11.9% in 2023 and 9.8% in 2024 to -5.2% in 2025, turning the company loss-making, while owners' net income flipped from a KRW 7.8bn profit in 2024 to a KRW 6.7bn loss in 2025.

On a quarterly basis, revenue contracted for three straight quarters from KRW 22.0bn in Q2 2025 to KRW 13.2bn in Q4 2025, with operating losses persisting in the range of roughly KRW 0.8bn to KRW 1.3bn.

In Q1 2026, revenue bottomed at KRW 14.3bn while the operating loss actually widened to KRW 3.1bn, reflecting simultaneous revenue weakness and margin deterioration. Revenue recovered double-digit in Q2 2026 to KRW 17.4bn and the operating loss narrowed somewhat to KRW 2.5bn, but the company remained in loss territory.

Over the trailing four quarters (Q3 2025 through Q2 2026), the cumulative owners' net loss reached roughly KRW 9.4bn, a loss magnitude well exceeding the full-year 2024 profit of KRW 7.8bn.

On the balance sheet, equity declined from KRW 77.1bn in 2024 to KRW 72.5bn in 2025, and the debt ratio rose back from 83.5% to 110.9% over the same period.

Operating cash flow, which had generated inflows of KRW 17.3bn and KRW 11.1bn in 2023 and 2024 respectively, turned negative at KRW -2.0bn in 2025, indicating strain in both earnings and cash generation.

Domestic construction activity showed a clear improvement in order indicators in the first half of 2026, but the recovery in coincident indicators such as construction starts and work-in-progress has failed to keep pace, leaving the sector in a mixed state.

According to CERIK, June 2026 construction orders fell sharply by -21.7% year-on-year, as public orders rose 29.2% while private orders dropped 41.5% in the opposite direction.

Construction work-in-progress in the same month rose modestly by 1.6% year-on-year to KRW 14.1tn, while construction sector employment fell 3.4% to 1.893mn workers, showing that employment recovery remains delayed.

The construction cost index rose 5.5% year-on-year to 138.22, adding to cost pressure, with concerns about further increases stemming from delayed effects of the Iran war.

The business sentiment index for construction firms continues to show a wide gap versus the all-industry average, reflecting relatively weak on-the-ground sentiment.

Because deck plate directly substitutes plywood formwork and is closely tied to construction start volumes, any delay in the recovery of starts and work-in-progress could also delay a normalization of revenue for makers like Winhitech.

The market has roughly eight competing manufacturers, with low-price order competition reportedly a persistent feature, meaning margin pressure tends to hit multiple players simultaneously during cost-inflation periods.

The company has continued to secure new orders across both the industrial and residential segments in 2026.

In July it signed a KRW 10.5bn single supply contract with SK Eco Plant for the Yongin Cluster 1 Phase 4 semiconductor fab (IBL FAB) construction project, and in August it disclosed a KRW 38.0bn single sales and supply contract for an LH-linked purchased-housing construction project pursued by its affiliate Incheon Sinpo Complex Development.

On the funding side, in July the company carried out a KRW 2.0bn third-party share placement to its largest shareholder S&N Global; the 935,017 new shares were issued at a 29% premium to the reference price, listed on August 11, and are subject to a one-year lock-up.

The company stated the proceeds would be used for research and development and other management purposes. Prior to that, in June, it also set up a KRW 2.0bn treasury stock trust as part of shareholder value management.

On the industry side, whether the improvement in order indicators translates into construction starts and work-in-progress will be a key determinant of the pace of earnings recovery, and the company's own revenue recovery is closely tied to that broader industry trajectory.

The certification obtained for Extra Deck from the Japan building center remains a potential avenue to reduce reliance on the domestic construction cycle, though recent disclosures have not confirmed a concrete expansion in export performance.
