Report overview

Defense Parts Monopoly, Earnings Still Volatile

Wave Electronics has shifted its center of gravity toward defense components, holding a monopoly supply position for guided-weapon parts to LIG Defense & Aerospace (formerly LIG Nex1), yet its quarterly earnings continue to swing between profit and loss.

1
As of 2025, over 80% of revenue came from the defense segment, marking a structural shift from a telecom equipment maker to a defense parts supplier.
2
The company holds a monopoly supply position for seekers and guidance control units to key customer LIG D&A, while subsidiary Adena is assessed as the No. 2 player in an oligopolistic power supply market.
3
Operating profit turned negative at -KRW 1.64 billion in 2025, but net income attributable to owners turned positive at KRW 1.48 billion, and operating cash flow improved markedly to KRW 10.57 billion.
4
The pattern of crossing the profit/loss line quarter to quarter continued, with a loss recorded in Q1 2026 followed by a return to profit in Q2 2026.
5
The company guided 2026 defense-segment revenue at KRW 57.5-61.7 billion, and its defense order backlog has repeatedly hit record highs.

Business structure

Wave Electronics operates two segments: a telecom segment supplying power amplifiers, filters, and RRH units for mobile base stations and repeaters, and a defense segment supplying seekers and guidance control units for guided weapons.

The telecom segment produces core modules for the RF transmission stage of wireless systems, with major customers including LG Uplus, SK Broadband, and railway-related companies.

The defense segment supplies seekers, guidance control units, and test equipment used in precision-guided munitions (PGM), and has also expanded into satellite and aerospace applications, developing SAR satellite backend systems and 5G satellite communication payload modem modules.

The defense segment's key customer is LIG Defense & Aerospace (LIG D&A), formerly LIG Nex1, with a Shinhan Investment analyst assessing that the company maintains a monopoly supply position for seekers and guidance control units.

Subsidiary Adena (formerly Microtech, 81% stake acquired in 2022) manufactures military and industrial power supply units and is assessed as holding the No. 2 share in an oligopolistic embedded-computer power supply market.

The company's products are used across LIG D&A's guided weapons lineup, from infantry systems such as Hyeongung and Bigung to medium-range guided missiles like Cheongung and Haegung, as well as L-SAM and anti-drone systems.

The business mix has been shifting from telecom equipment toward defense components, with over 80% of 2025 revenue coming from the defense segment. The largest shareholder has remained CEO Park Cheon-seok without change since the company's founding.

Earnings analysis

Consolidated revenue in 2025 was KRW 80.53 billion, up slightly from KRW 78.04 billion in 2024, but operating profit swung to a loss of KRW 1.64 billion from a profit of KRW 1.85 billion the prior year. The operating margin slipped from 3.0% in 2023 to 2.4% in 2024 before turning negative at -2.0% in 2025.

Net income attributable to owners, however, turned positive at KRW 1.48 billion in 2025, an improvement from the large net loss of KRW 6.35 billion in 2024. Operating cash flow reached KRW 10.57 billion in 2025, a marked improvement from negative flows of KRW 9.38 billion in 2022 and KRW 1.74 billion in 2023.

Quarterly results show clear seasonality: from a Q2 2025 revenue of KRW 16.99 billion and an operating loss of KRW 0.78 billion, Q3 revenue rose to KRW 21.72 billion, narrowing the operating loss to KRW 0.14 billion and turning net income positive at KRW 0.47 billion.

Q4 posted the year's strongest results, with revenue of KRW 24.61 billion, operating profit of KRW 0.28 billion, and net income of KRW 2.36 billion.

However, Q1 2026 revenue fell to KRW 15.81 billion with an operating loss of KRW 1.13 billion and a net loss of KRW 1.06 billion, before Q2 2026 swung back to profit with revenue of KRW 20.98 billion, operating profit of KRW 0.99 billion, and net income of KRW 0.78 billion.

Over the trailing four quarters (Q3 2025-Q2 2026), combined revenue totaled roughly KRW 83.1 billion and net income attributable to owners about KRW 2.54 billion, showing continued improvement on an annual basis even though quarter-to-quarter swings remain wide enough that a stable trajectory cannot yet be confirmed.

Industry analysis

Korea's defense industry is in a strong growth cycle centered on export expansion. Wave Electronics' key customer, formerly LIG Nex1, marked its 50th anniversary in March 2026 by renaming itself LIG Defense & Aerospace (LIG D&A) and declaring an expansion combining defense and aerospace businesses.

LIG D&A posted 2025 revenue of KRW 4.31 trillion (up 31.5% year over year) and operating profit of KRW 322.9 billion (up 44.5%), with strong exports of systems such as Cheongung-II cited as the main driver.

The combined order backlog of Korea's top five defense firms (Hanwha Aerospace, Hyundai Rotem, Korea Aerospace Industries, LIG Nex1, and Hanwha Systems) nearly tripled, from KRW 30 trillion in 2021 to KRW 83 trillion in 2024.

The possibility of Bigung exports to the United States has also emerged as a focal point, with assessments that the system has effectively met baseline requirements after all six final test shots hit their targets in a U.S. Department of Defense Foreign Comparative Testing evaluation.

Expanding Middle East orders combined with expectations of increased European defense spending have also driven a broadening of buying interest from finished-system makers to component suppliers.

Within this value chain, Wave Electronics is positioned as a component supplier holding a monopoly on seeker and guidance control unit supply, while subsidiary Adena holds the No. 2 position in an oligopolistic power supply market.

In contrast, the mobile telecom equipment market that houses the company's telecom segment has entered a mature phase of 5G investment with slowing growth, and the company itself has issued a conservative outlook for that segment.

Outlook

The company has guided 2026 defense-segment revenue at KRW 57.5-61.7 billion, up 35-45% from KRW 42.6 billion in 2025. The telecom segment maintains a relatively conservative outlook, so overall revenue growth is being restructured to be led by the defense segment.

On the order front, the backlog stood at KRW 167.8 billion as of Q1 2025, entirely from the defense segment, surpassing the previous record of KRW 146.1 billion set at the end of 2024.

A company representative said defense growth would offset the decline in telecom revenue and expected the order increase to continue through year-end.

In terms of diversifying growth drivers, the company is expanding into satellite and aerospace fields, including SAR satellite backend systems and 5G satellite communication payload modem modules.

However, these new businesses remain at an early stage with limited revenue contribution so far, and most current earnings still stem from existing seeker, guidance control unit, and power supply deliveries. If large export events such as a potential U.S.

Bigung export by LIG D&A materialize, spillover effects on orders for component partner Wave Electronics would be expected.

Over the past five quarters, the company has moved back and forth between operating losses and profits, and the market's assessment of earnings stability appears to be reflected in the valuation as well.

The price-to-book ratio sits near net asset value, a higher level than the discounted range seen during past periods of weak performance.

The price level relative to earnings tends to swing depending on whether a given quarter turns profitable, a pattern tied to the small-cap tendency for operating profit to frequently cross the break-even line.

No dividend has been paid for the most recent fiscal year, suggesting capital is being prioritized toward defense-segment investment and balance sheet improvement rather than shareholder returns.

Ultimately, the level at which the shares currently trade can be seen as reflecting two offsetting factors at once: the structural growth story in the defense segment, and stagnation in the telecom segment combined with quarterly earnings volatility.

Bull factors

Monopoly Position in Defense Component Supply

Wave Electronics maintains a monopoly supply position for seekers and guidance control units to LIG D&A (formerly LIG Nex1), a point highlighted as a key investment thesis in Shinhan Investment research. The defense segment has become the company's core business, accounting for over 80% of 2025 revenue.

If the company's 2026 defense revenue guidance of KRW 57.5-61.7 billion materializes, the overall business's reliance on defense is set to deepen further.

Growing Order Backlog and Improving Cash Flow

The defense order backlog grew from KRW 146.1 billion at the end of 2024 to KRW 167.8 billion in Q1 2025, again setting a record high. Operating cash flow reached KRW 10.57 billion in 2025, a clear improvement from negative flows in 2022-2023.

Given the lag between order intake and revenue recognition typical of the defense industry, the growing backlog can be seen as improving future revenue visibility.

Potential Beneficiary of K-Defense Export Growth

Customer LIG D&A holds a diverse export pipeline, including Cheongung-II sales to the UAE and Saudi Arabia and the potential for Bigung exports to the United States.

The broader industry growth, with the top five Korean defense firms' order backlog rising from KRW 30 trillion in 2021 to KRW 83 trillion in 2024, also provides a favorable environment for component supplier Wave Electronics.

Analysts have noted that expanding exports by finished-system makers are spreading buying interest to component suppliers as well.

Bear factors

Quarterly Earnings Volatility and Renewed Losses

Q1 2026 revenue fell sharply from the prior quarter to KRW 15.81 billion, with an operating loss of KRW 1.13 billion and a net loss of KRW 1.06 billion, marking a return to losses.

In 2025 as well, the company swung from an operating loss in Q2 to a profit in Q3, yet posted a full-year operating loss overall, repeatedly crossing the break-even line.

This quarter-to-quarter variability appears to stem from the timing of defense revenue recognition overlapping with irregular demand in the telecom segment.

Stagnant Telecom Segment

The company's telecom segment maintains a conservative outlook even into 2026, meaning its share of total revenue could continue to shrink. The mobile telecom equipment market, having entered a mature phase of 5G investment, is also not a favorable environment for telecom segment growth. If telecom revenue stagnation persists, the benefits of business diversification could remain limited.

Customer and Revenue Concentration Risk

Defense-segment revenue and orders are effectively concentrated in a single customer, LIG D&A, so changes in that customer's ordering schedule or procurement policy could directly affect the company's results.

The potential Bigung export to the United States has not yet reached an actual contract stage, and market attention is shifting to the actual timing and scale of any order. If a major export event is delayed or scaled back, the pace of backlog growth for component partner Wave Electronics could adjust accordingly.

Risk factors

Customer Concentration Risk

The core defense customer is effectively concentrated in LIG D&A alone, resulting in high dependence on a single client. Any change in that customer's business strategy or procurement policy could immediately affect Wave Electronics' orders and revenue.

Conversely, a major export success by the customer could also benefit partner Wave Electronics, so this should be viewed as a risk that can cut both ways.

Export Contract Uncertainty

A potential Bigung export to the United States is assessed as having met requirements in a U.S. Department of Defense Foreign Comparative Testing evaluation, but no actual contract has been finalized. Market commentary also suggests it is difficult to predict the direction of related developments.

Given the uncertain timing and scale of any major export contract, it may take time before related expectations translate into actual results.

Earnings Volatility and Small-Cap Characteristics

Over the past five quarters, operating results have alternated between profit and loss, indicating relatively low earnings stability. As a small-cap stock, share price volatility can increase sharply around earnings releases or order news.

While balance sheet improvement is underway, the profit base remains thin, which could limit the company's buffer against external shocks.

Overall view

Wave Electronics has made considerable progress in its transition to a defense component supplier, securing a monopoly position supplying seekers and guidance control units across LIG D&A's guided weapons lineup, with its order backlog continuing to hit record highs.

The modest improvement in 2025 revenue and net income attributable to owners, along with the marked improvement in operating cash flow, are positive signals from a balance sheet perspective.

However, operating profit swung back to a loss in 2025, and the pattern of crossing the profit/loss line repeated into 2026 with a Q1 loss followed by a Q2 profit, meaning earnings stability has not yet been firmly established.

While the telecom segment remains stagnant under a conservative outlook, dependence on defense-segment growth is increasing, a structure that heightens sensitivity to a specific customer and specific export events. The K-defense export growth story, including a potential U.S.

Bigung export, could serve as a positive catalyst, but it should also be considered an expectation factor for which no actual contract has yet been finalized.

Investors may find it useful to track the upcoming Q3 and Q4 results, progress toward the defense revenue guidance, and the actual timing of any major export contract as they develop.
