Financial Structure Trend

Valuation (Factual Multiples)

Market capitalization of KRW 30.615 billion (closing price KRW 760 × 40,283,149 shares outstanding, as of 2026-08-04, DART settlement date 2026-03-31) was used as the authoritative figure; EV/EBITDA could not be calculated due to unavailable net debt and EBITDA line-item data.

Competitive Landscape

The global optical fiber fusion splicer market is understood to be an oligopoly dominated by three Japanese companies (combined share of 82.6% as of 2018; latest figures not available), and INNO Instrument is understood to have maintained the No.1 market share in China's domestic market on the strength of cost competitiveness through its production subsidiary in China. The company has stated in its business report that average selling prices are on a declining trend amid intensifying competition (original text not reviewed; cited).

Supply-Demand Trends (Past 1 Month)

Large-scale net foreign selling on the single trading day of 2026-07-23 (KRW -844 million) appears to have driven the 1-month cumulative figure into negative territory, and retail investors generally showed a pattern of moving in the opposite direction to foreign investors. The short-selling balance ratio was 0.86% (as of 2026-07-31, E); the short-selling ratio (relative to trading value) and the foreign ownership limit utilization rate are not available. The figures above are pykrx-based estimates that have not been cross-checked against official KRX aggregated data.

Governance Structure

On 2026-03-31 the CEO changed from Park Cho-young to GAO FEI, and on 2026-04-07 GAO FEI was included as a specially related party of Jo Bong-il, increasing the group's combined stake from 28.45% to 28.91%. Subsequently, per a disclosure dated 2026-04-24, Jo Bong-il's individually held shares decreased by 351,975 shares (-0.87%p) to 24.85%, with the specific reason for the decrease not available. INNO Instrument has 13 unlisted affiliated companies (located in China, Europe, the United States, India, Japan, Hong Kong, Malaysia, the United Kingdom, and Indonesia) and no listed affiliates.

Macro Environment

Given that approximately 98% of revenue is generated overseas, a rise in the KRW/USD exchange rate (won depreciation) is linked to an increase in won-converted revenue and gross profit, while a domestic base rate hike increases the burden of interest expenses and working capital financing amid the operating loss. The US and European optical fiber cable markets are projected to grow at an average annual rate of 9.05% from 2026 to 2031, with 5G densification and expanding investment in AI hyperscale data center-driven optical communication infrastructure cited as revenue drivers.

Key Points of Caution

• The debt-to-equity ratio rose from 31.4% at end-2022 to 97.6% at end-March 2026, and over the same period total equity decreased by approximately 64%, from KRW 97.62 billion to KRW 35.18 billion (Value Line aggregation, E).
• Operating and net losses continued for three consecutive years from 2023 to 2025, and while the loss has been narrowing since 2025, the company remains in a loss-making position (A).
• The capital impairment ratio, whether the stock has been designated as an administrative issue or investment-caution issue, and the most recent audit opinion (including whether it contains a going-concern emphasis-of-matter) are not available and require separate verification against the original DART filings.
• More than 90% of revenue is concentrated in the single product category of optical fiber fusion splicers, and approximately 98% of revenue is generated overseas, exposing the company to exchange-rate volatility.
• The business report states that downward pressure on average selling prices continues due to the market entry of low-cost local Chinese competitors (original text not reviewed; cited).
• Following the short-term surge in March-April 2026, the Korea Exchange designated the stock as an investment-alert issue and an investment-risk issue and imposed trading halts; the 5-to-1 reverse stock split resolved on 2026-07-31 is scheduled to take place during September-October 2026.
