Gaon Cable (000500) In-Depth Analysis:
Post +306% Power Grid Rally Valuation & Earnings Assessment
Gaon Cable delivered stellar 2025 operating profit of 79.2B KRW (+76.0% YoY) and maintained momentum into Q1 2026. However, its YTD stock surge (+306% to +351%) has far outpaced current earnings. Considering the rising debt ratio (2025.5%) and institutional profit-taking, investors should avoid chasing the rally and wait for staged entries on post-earnings pullbacks.
Company Overview & Governance: LS Cable Affiliate Premium & Floating Shares
Gaon Cable (000500) specializes in power cables, insulated wires, and telecommunication cables. The company is a key beneficiary of structural tailwinds including AI data center buildouts, renewable energy integration, electrification, and aging power grid replacements.
4 Core Drivers Behind the 2026 Stock Rally (+306%)
| Driver | Details & Market Interpretation |
|---|---|
| 1. Power Infrastructure Re-rating | AI data center power demand requires massive cable expansions across sub-stations and distribution grids, elevating cable makers from cyclical suppliers to infrastructure plays. |
| 2. Earnings Acceleration | 2025 operating profit soared +76.0% (79.2B KRW) and net profit surged +102.7% (51.4B KRW). Q1 2026 OP continued the streak with +27.2% YoY growth. |
| 3. Supply Squeeze & Group Momentum | With free float under 18.4%, capital inflows triggered a severe supply squeeze. Strategic ties with LS Cable sparked global project win expectations. |
| 4. Stock Price Front-Running Earnings | The stock rallied from 41,910 KRW in Dec 2025 to 188,900 KRW (peak 352,778 KRW), pushing valuation into high PER territory well ahead of fundamental growth. |
Financials & Balance Sheet: Earnings Surge vs. Rising Leverage
| Metric (Consolidated) | 2023 | 2024 | 2025 | Q1 2026 |
|---|---|---|---|---|
| Revenue (100M KRW) | 1,499 | 1,727 | 2,546 (+47.5%) | 764 (+19.4%) |
| Operating Profit (100M KRW) | 437 | 450 | 792 (+76.0%) | 278 (+27.2%) |
| Net Income (100M KRW) | 179 | 254 | 514 (+102.7%) | 197 (+28.3%) |
| Operating Margin (OPM) | 2.9% | 2.6% | 3.1% | 3.65% |
| Debt Ratio (Financial Drag) | 129.8% | 184.8% | 184.8% | 202.5% (Warning) |
Operating margin expanded modestly to 3.1% in 2025 and 3.65% in Q1 2026, though overall profitability remains relatively low. Raw material cost spikes (copper) and working capital demands pushed the **debt ratio up sharply from 129.8% in 2024 to 202.5% in Q1 2026**, raising interest expense burdens in a high-rate environment.

Recent 30-Day Net Cumulative Buying Volume (Shares)

Scenario Analysis & Actionable Investment Strategy
3 Core Conditional Scenarios
Surging global grid & data center cable wins + OPM holding above 4.0% with 2026 net income surpassing 100B KRW
Revenue growth continues while OPM stabilizes around 3.5%, leading to multiple consolidation
Copper price spikes/FX volatility + high debt ratio (202.5%) interest burdens lead to earnings disappointment
💡 Bottom Line: Solid Earnings Momentum, But Valuation Is Front-Loaded!
1. New Entry Guidance: Chasing the stock at current levels carries elevated risk due to heavy PER multiples (60.8x) and institutional selling. Wait for staged accumulation on post-earnings pullbacks.
2. Key Milestones to Watch: ① Continuous quarterly OP growth, ② OPM expanding above 4.0%, ③ Debt ratio stabilization.
3. Portfolio Allocation: Rather than concentrating heavily in a single stock, diversification across transformers, power equipment, and cable makers is strongly recommended.
