Kiwoom Securities flags Roche Systems as deeply undervalued at 5.2x forward earnings

Kiwoom Securities published a research brief on September 3rd arguing that Roche Systems (KOSDAQ: 071280), a maker of material-handling equipment for the semiconductor and display industries, is trading at just 5.2 times its projected 2026 earnings — a level the brokerage describes as a significant undervaluation.

The note, authored by Oh Hyun-jin, a small-cap analyst at Kiwoom, forecasts Roche Systems' 2026 annual revenue at 195.8bn won, up 57% year on year, with operating profit rising 61% to 23.3bn won. The operating margin is expected to improve modestly to 11.9%, from 11.5% the previous year.

What the company makes

Roche Systems produces equipment used in semiconductor fabrication, including EFEMs (Equipment Front End Modules) and load ports, as well as flat-panel display (FPD) logistics equipment such as indexers, flexible printed circuit board (FPCB) bending modules, and glass-cutting machines (GCM). As of the second quarter of 2026, its semiconductor division accounts for 54% of total revenue, with the display segment contributing 39%.

Two core growth drivers

The brokerage identifies two principal engines of growth. The first is the company's EFEM business, which supplies equipment to Chinese semiconductor manufacturers via Mattson Technology, an American semiconductor equipment firm. As Chinese chipmakers continue to invest heavily in domestic production capacity amid the broader US-China technology rivalry, demand for these products has grown steadily.

The second driver is the nitrogen purge adaptor (N2 Purge Adaptor), a component that injects nitrogen gas into wafer storage containers (FOUPs) to improve manufacturing yields. This product is supplied directly to South Korea's leading integrated device manufacturers (IDMs). With the semiconductor industry broadly intensifying investment in yield-improvement technologies, this product's revenue contribution is rising.

Order backlog at record levels

Forward-looking indicators are encouraging. At the end of the second quarter of 2026, the semiconductor division's order backlog stood at 62.8bn won — a 251% surge year on year and the highest level on record. Compared with the end of the first quarter alone, the backlog grew by more than 60%, providing greater visibility into second-half earnings.

Display division recovering

The display segment is also regaining momentum. Revenue from that division in the first half of 2026 reached 40.5bn won, up 24% year on year. The previous year had been sluggish, as the company's major domestic display clients made no significant new capital investments. This year, however, refurbishment and upgrade spending on existing production lines has resumed. In the second half, further tailwinds are expected from back-end process investment by South Korean display manufacturers supplying panels for a North American smartphone maker's forthcoming foldable handsets. Roche Systems supplies FPCB bending module equipment used to attach flexible circuits to display panels, as well as inspection equipment for ultra-thin glass (UTG).

A fortress balance sheet

The company's financial position is similarly robust. By the end of 2026, its net debt-to-equity ratio is projected at -34.1%, indicating a net cash position with effectively no borrowings. Total debt stands at just 300m won, against cash and cash equivalents of 51.1bn won. Its interest coverage ratio of 1,261.7 times leaves little room for concern about financial health.

Risks to consider

Investors should nonetheless weigh several risks. The share price has fallen 51.4% from its 52-week high of 13,610 won, closing at 6,620 won on September 2nd. Much of the earlier rally had been driven by enthusiasm over glass substrate technology — a next-generation semiconductor packaging material that attracted speculative interest across the sector. As commercialisation timelines have been pushed back, the shares of companies seen as beneficiaries, including Roche Systems, have retreated sharply.

A foreign ownership rate of 46.3% is another source of potential volatility: any unwinding of overseas positions could weigh on the share price. Additionally, a substantial portion of EFEM revenues is directed at Chinese clients, leaving the company exposed to any tightening of US export controls or broader restrictions on semiconductor-related trade with China.

Historical context and valuation

Roche Systems peaked operationally in 2022, with revenue of 144.6bn won and operating profit of 26.4bn won. The following year, a cyclical downturn pushed those figures down sharply, to 105.3bn won and 11.9bn won respectively. A recovery in 2024 — revenue of 160.1bn won, operating profit of 19.8bn won — was followed by another setback in 2025, when revenue slipped to 124.9bn won and operating profit to 14.4bn won. Should the 2026 forecasts prove accurate, the company would set new all-time records on both measures.

At 5.2 times forward earnings, Roche Systems trades at a substantial discount to the 15–20x P/E multiples typical of comparable South Korean semiconductor equipment companies. Its EV/EBITDA of 1.8 times also sits well below its historical average of 4–10 times. Kiwoom Securities did not set an explicit target price, but was unequivocal in its conclusion: even on conservative estimates, the shares look cheap.
