Report overview

Defense Lifts Profits; Telecom Remains the Open Question

Overseas defense orders and the optical-components subsidiary have transformed RFHIC's earnings power in a short span; the remaining variable is when telecom revenue tied to the U.S. spectrum cycle actually lands.

1
Annual operating margin jumped from around 1% in 2022-2024 to 16.6% in 2025, and the quarterly operating margin exceeded 21% in 2Q26 (per confirmed financials).
2
In February 2026 the company signed a KRW 50.6bn high-power amplifier supply contract with Raytheon Canada, running through February 1, 2027.
3
Management raised 2026 guidance to KRW 260bn revenue and KRW 48bn operating profit, yet confirmed first-half figures stand at KRW 94.6bn and KRW 18.9bn, implying heavy second-half dependence.
4
The U.S. FCC adopted rules in July 2026 to auction 160 MHz of Upper C-band spectrum, with Auction 115 scheduled for April 27, 2027, pushing the telecom investment restart further out.
5
Subsidiary RF Materials has rapidly scaled pump-laser package sales to Lumentum, lifting profit contribution, while the core telecom business recovery is still to be confirmed.

Business structure

Founded in 1999 and listed on KOSDAQ in 2017, RFHIC designs and mass-produces gallium nitride (GaN) transistors and power amplifiers. Its business spans three pillars: telecommunications, defense, and RF energy.

Based on 2024 disclosures, the revenue mix was GaN power amplifiers 77.08%, GaN transistors 16.95%, GaAs MMIC 0.72%, and merchandise/other 5.25% (Daily Invest, April 2025).

On the telecom side, the key customer is Samsung Electronics, to which RFHIC has supplied in-house GaN transistors and power amplifiers used in base station equipment sold to domestic and overseas carriers.

In defense, the company disclosed a KRW 50.638bn high-power amplifier supply contract with Raytheon Canada in February 2026, and domestically it supplies radar power amplifiers for the Cheongung-II air-defense system through LIG Nex1.

Consolidated subsidiaries include RF Materials, which supplies pump-laser packages to Lumentum, and RF Systems, selected as a defense sub-system supplier within the LIG group.

Competitively, the company states in its annual report that while global rivals concentrated on silicon-based LDMOS, it mass-produced GaN for telecom applications and built a competitive cost structure.

Its ability to produce GaN transistors and amplifiers in-house from material to module is cited as a structural strength.

More recently, it won a KRW 18.7bn order for a high-power RF amplifier system (SSPA) for a fourth-generation multipurpose synchrotron radiation facility, extending RF energy into national research and industrial infrastructure (company announcement, February 2026).

Earnings analysis

The shift in the profit structure is dramatic. Revenue was KRW 108.0bn in 2022, KRW 111.4bn in 2023 and KRW 114.9bn in 2024 - essentially flat for three years - while operating profit was only KRW 0.80bn, KRW 0.30bn and KRW 1.53bn respectively, implying margins of 0.3-1.3%.

In 2025, revenue reached KRW 185.8bn (up roughly 62% year on year) with operating profit of KRW 30.9bn and a 16.6% operating margin, a discontinuous improvement.

Notably, in 2023 and 2024 net profit attributable to owners was KRW 17.4bn and KRW 25.7bn despite negligible operating profit, suggesting earnings leaned heavily on non-operating items.

By contrast, in 2025 operating profit of KRW 30.9bn and owners' net profit of KRW 28.7bn were of similar magnitude, indicating earnings quality shifted toward the core business.

Quarterly, 2Q25 posted KRW 44.6bn revenue and KRW 8.3bn operating profit, 3Q25 KRW 40.5bn and KRW 7.4bn, and 4Q25 KRW 68.8bn and KRW 11.5bn, a clear back-half-weighted seasonal pattern.

In 2026, 1Q delivered KRW 43.1bn revenue and KRW 7.7bn operating profit (18.0% margin) and 2Q KRW 51.5bn and KRW 11.2bn (21.7% margin), lifting quarterly margins another notch, with 2Q operating profit up about 35% year on year.

That said, versus KB Securities' April 2026 estimate for the second quarter (KRW 58.8bn revenue, KRW 10.5bn operating profit), confirmed revenue came in lower, meaning margins improved ahead of the top line.

On the balance sheet, the debt-to-equity ratio fell from 55.2% in 2023 to 37.8% in 2025, and 2025 operating cash flow of KRW 29.5bn was broadly in line with operating profit.

Industry analysis

The wireless telecom equipment cycle has not yet confirmed a genuine recovery.

In a March 2026 industry report, Shinhan Securities noted that Ericsson, Nokia and Dell'Oro all expect 2026 wireless equipment conditions to be roughly flat versus the prior year, with both vendors emphasizing cost control and profitability over revenue expansion. On the supply side, however, change is underway.

Competitor NXP has effectively withdrawn from telecom to focus on automotive, while the EU has followed the U.S. in tightening restrictions on Chinese equipment and components (Hana Securities, March 2026).

Against this backdrop, the prospect of Korean suppliers being added to global system integrators' vendor lists has been repeatedly raised. Spectrum schedules serve as a leading indicator for the cycle.

Spectrum auctions are typically read as a leading indicator of carrier capex, and the FCC voted at its July 2026 meeting to auction 160 MHz of Upper C-band spectrum, with that auction (Auction 115) scheduled for April 27, 2027.

Defense demand follows a separate cycle, with radar and interceptor programs expanding after Middle East conflicts and pulling GaN amplifier demand higher.

Data center and optical demand flows through the subsidiary: RF Materials' sales to Lumentum were described as growing from KRW 4bn in 2024 to KRW 11bn in 2025 and around KRW 25bn in 2026 (brokerage estimates, April 2026).

In short, the current position is asymmetric: defense and optical components are in an upcycle, while the core telecom business is still waiting.

Outlook

The company's full-year target has been raised. Following first-quarter 2026 results, RFHIC was reported to have lifted annual guidance from KRW 240bn to KRW 260bn in revenue and from KRW 40bn to KRW 48bn in operating profit (Daily Invest, April 2026).

Against confirmed first-half figures of KRW 94.6bn revenue and KRW 18.9bn operating profit, the second half carries overwhelming weight, so delivery hinges on how quickly defense volumes convert to revenue.

On orders, defense wins secured in the first quarter - KRW 50.6bn from Raytheon in February and KRW 19.2bn from LIG Nex1 in March - were described as beginning to flow into results (KB Securities, April 2026).

For telecom, one view held that a decision on Ericsson vendor selection would become visible within the first half (Shinhan Securities, April 2026), and another projected that sales to Samsung Electronics and Ericsson would ramp after the U.S. spectrum auction (Hana Securities, June 2026).

However, the Upper C-band auction itself is set for April 2027, leaving timing risk around telecom revenue.

In new businesses, the company is pursuing RF power generators for semiconductor deposition and etching processes, and one analyst suggested co-packaged optics (CPO) related revenue could begin as early as the fourth quarter (KB Securities, April 2026).

On price targets, KB Securities presented KRW 120,000 in an April 2026 report, while Hana Securities stated in a June 2026 report that it was maintaining KRW 150,000.

The valuation debate here centers on how durable the new profit level is.

With operating profit near break-even in 2022-2024 before settling into a double-digit margin from 2025, earnings-based multiples are hard to compare directly with the depressed years, and the current price-to-earnings multiple is perceived as sitting near the upper end of the range that Korean telecom equipment names typically commanded during past cycle expansions.

Relative to net assets, the stock trades at a premium, and interpretations diverge depending on how much value is assigned to the defense order backlog and subsidiary stakes.

One brokerage argued in an August 2026 report that, on 2027 estimated earnings, the price-to-earnings multiple of about 18 times sits below the post-2018 average of 24 times - though that rests on that firm's own forecasts, and a change in estimates changes the conclusion.

Dividends continue in the form of a year-end cash payout, but the return relative to profit is modest, so the dividend yield is on the low side and the investment axis lies in earnings durability rather than income.

Ultimately, whether the gap between confirmed first-half results and full-year guidance narrows is the test of the reasoning behind the current multiple.

Bull factors

Overseas Defense Has Reset the Margin Level

The 21.7% operating margin in 2Q26 sits a notch above the 16.6% full-year 2025 level, consistent with the view that a rising share of high-margin overseas defense work has changed the margin structure.

KB Securities estimated in a February 2026 report that highly profitable overseas defense revenue was growing sharply and that the defense share of sales would expand to 66% in 2026.

It also noted that recognizing Raytheon-related revenue over a year should improve revenue visibility from backlog accumulation and smooth earnings seasonality. That confirmed quarterly margins stayed above 18% in both 1Q and 2Q 2026 suggests the structure may not be temporary.

A Structural Seat Created by Supplier Attrition

Analysts have argued that competitor NXP effectively exited telecom to focus on automotive, and that with the EU following the U.S. in restricting Chinese equipment and components, the supply-side environment is shifting (Hana Securities, March 2026).

Among Korean suppliers, RFHIC has repeatedly been cited as a candidate for new global vendor status. If a structure of more demand and fewer suppliers genuinely takes hold, there is room for improvement in pricing power and utilization. Still, this is a hypothesis that must be validated by an observable event such as vendor selection.

A Second Profit Axis From Subsidiaries

RF Materials supplies pump-laser packages to Lumentum, with related sales described as rising from KRW 4bn in 2024 to KRW 11bn in 2025 and around KRW 25bn in 2026, and the unit reportedly posted KRW 10bn in standalone first-quarter 2026 revenue at a margin above 20%.

One view held that co-packaged optics revenue could start as early as the fourth quarter (KB Securities, April 2026). Even if the core telecom recovery is delayed, optical and data center demand now provides a cushion for consolidated profit. RF Systems, selected as a defense sub-system supplier, forms yet another profit axis.

Bear factors

The Gap Between Guidance and Actual First-Half Results

On confirmed quarterly data, first-half 2026 cumulative revenue was KRW 94.6bn with operating profit of KRW 18.9bn. Against the raised annual target of KRW 260bn revenue and KRW 48bn operating profit, the second half would need to generate more than 1.7 times first-half revenue.

While the business is described as back-half weighted, with profit rising toward the fourth quarter, any slippage in large defense shipments would widen the gap between target and reality. Indeed, confirmed 2Q26 revenue came in below brokerage estimates.

The Telecom Cycle Restart Keeps Sliding Right

The U.S. Upper C-band auction (Auction 115) is scheduled for April 27, 2027. Winners could begin service in the top 75 markets only from December 2030, so spectrum acquisition does not translate immediately into equipment orders.

The fact that Ericsson, Nokia and Dell'Oro see 2026 wireless equipment conditions as flat and are emphasizing cost control also caps near-term order intensity (Shinhan Securities, March 2026). If the telecom recovery keeps slipping, earnings concentration in defense deepens.

Dependence on a Few Customers and Contracts

A single Raytheon Canada contract equated to 44% of the prior year's annual revenue, showing how much weight individual deals carry. On the telecom side, the performance of Samsung Electronics' network business has long had a substantial influence on results.

A change in one customer's program schedule or budget immediately amplifies quarterly volatility. Diversification is described as underway, but it is too early to verify the effect in confirmed results.

Risk factors

Order Recognition Timing Risk

Defense contracts carry a long lag between signing and revenue recognition. The Raytheon Canada contract (KRW 50.6bn) specifies a term from February 13, 2026 to February 1, 2027, so any shipment delay can swing a given quarter materially.

Confirmed 2Q26 revenue falling short of street estimates is not unrelated to this lag effect. Rather than reading any single quarter as a trend, cumulative recognition pace should be tracked alongside.

Policy and Regulatory Variables

A large share of the opportunity set is tied to regulatory calendars. The Upper C-band auction proceeds under a statutory deadline to complete competitive bidding by July 4, 2027, and the transition schedule is linked to aircraft radio altimeter interference issues, so procedural delay cannot be ruled out.

Defense exports likewise depend on export approvals and government budgets. While tighter restrictions on Chinese equipment and components are seen as favorable, regulation is a variable whose direction can reverse.

FX and Cost Volatility

With a high export share, currency moves feed directly into margins. In the first quarter of 2026, a weaker won alongside improved subsidiary results was cited as driving earnings growth. Conversely, a stronger won compresses margins on the same volumes.

Procurement prices and supply stability for key materials such as GaN-on-SiC wafers are additional cost variables.

What to watch next

Mid-November 2026
Third-quarter 2026 results disclosure. Key checks are whether Raytheon and U.S. air traffic control related defense volumes have begun converting into revenue, and whether the roughly 21% operating margin posted in the second quarter holds.
Fourth quarter 2026
Disclosures or reports on Ericsson vendor selection and telecom volumes for Samsung Electronics. This was expected by some to become visible within the first half, and it is the pivotal event determining whether telecom revenue resumes.
November 5 - December 15, 2026
Under the U.S. Upper C-band transition process, eligible space station operators must file initial transition plans by November 5 and a clearinghouse candidate must be identified by December 15. Whether these deadlines hold is a leading indicator for the 2027 auction and subsequent equipment orders.
January - February 2027
Full-year 2026 results and year-end dividend disclosure, plus whether a follow-on order emerges as the Raytheon Canada contract expires on February 1, 2027. This is the point at which achievement versus raised guidance and the continuity of defense orders can be checked together.
April 27, 2027
Scheduled start of the U.S. Upper C-band auction (Auction 115). Auction outcomes and winners' capex plans will serve as the benchmark for gauging order volumes across the Korean telecom equipment value chain.

Overall view

RFHIC's earnings profile changed character from 2025.

After a stretch in which revenue stagnated between KRW 108.0bn and KRW 114.9bn in 2022-2024 with operating profit near break-even, the company posted KRW 185.8bn in revenue and KRW 30.9bn in operating profit (16.6% margin) in 2025, and its quarterly operating margin reached 21.7% in 2Q26.

The drivers were high-margin overseas defense orders and the optical-components subsidiary, while the debt-to-equity ratio fell from 55.2% in 2023 to 37.8% in 2025, improving financial flexibility.

On the other hand, the raised 2026 target is heavily back-half weighted, so shipment and recognition pace for defense volumes will determine whether it is met. The core telecom business remains tied in timing to the U.S.

Upper C-band auction scheduled for April 2027 and to Ericsson vendor selection, keeping the lag between expectations and actual revenue in focus. Valuation hinges on judgments about how durable the newly established profit level is, which the next two or three quarters of results will test.
