Taihan Cable Submarine Cable Plant 2 Investment Memo

A filing-based review of the KRW 497.2 billion capacity expansion for offshore wind and submarine cable demand

Date: 2025-07-16 · Filing-based CAPEX review · Naver Blog and DART

Investment decisions are your own responsibility. This material is research and is not a recommendation to buy or sell.

0. Bottom line first

The filing says Taihan Cable will invest KRW 497.2 billion in phase 1 of its second submarine cable plant. The amount is substantial: 33.2% of equity and 16.6% of market capitalization.

Official fact: The source records Taihan Cable’s market capitalization at KRW 2.9701 trillion and the current price at KRW 15,930 at the time of the filing. The investment starts on 2025-07-16, ends on 2027-12-31, and runs for 2.5 years.

Interpretation: This reads less like routine expansion and more like proactive CAPEX tied to offshore wind and submarine cable market growth. Because the ticket size is large, orders, utilization, and funding conditions need to be tracked together.

CAPEX

Investment amount

KRW 497.2 billion for construction, manufacturing equipment, inspection equipment, and related phase-1 plant items.

BALANCE

Versus equity

33.2%. This is a meaningful investment relative to the company’s capital base.

MARKET CAP

Versus market cap

16.6%. The event increases both the growth optionality and the burden the market has to discount.

1. Investment Purpose

Official fact: The investment type is new facility investment. The stated purpose is phase 1 of the second submarine cable plant, including buildings, manufacturing equipment, and inspection equipment, to secure product capacity as offshore wind and submarine cable markets expand.

Interpretation: The key question is how quickly this capacity becomes usable production. Offshore wind projects value long-term delivery reliability, so the real test is not just the buildout but backlog and profitability after ramp-up.

2. Timeline And Watch Points

Investment amountKRW 497.2 billionOrders and funding burden need to be checked together
Versus equity33.2%Large enough to matter on the balance sheet
Versus market cap16.6%Market expectations and risk can both rise

My checklist is simple: whether submarine cable backlog follows the expansion, whether debt or cash-flow pressure increases during the investment period, and whether phase 1 leads to further phases later.
