Sebo MEC

What Sebo MEC does

Sebo MEC is a South Korea-based engineering and construction firm headquartered in Seoul and publicly listed on KOSDAQ (ticker: 11560). Founded in 1978, the company operates with 51-100 employees and focuses on domestic engineering and construction projects, meaning it delivers infrastructure, industrial, or commercial construction services within the Korean market rather than pursuing international contracts.

The company's revenue model is project-based, relying on contract wins with Korean counterparties. Financial data indicates revenue of approximately 716 billion KRW in fiscal year 2025 (~$540M USD at current exchange rates), down from ~1,032 billion KRW in 2022 — a roughly 30% three-year contraction. Despite the top-line decline, EBITDA margin expanded from 3.6% (2022) to 7.5% (2025), and net income rose from 23.6 billion KRW to 35.6 billion KRW over the same period, consistent with a deliberate strategy of prioritizing higher-margin work over volume. A recently disclosed single order of approximately 40 billion KRW (~$30M USD) illustrates the contract scale on which the company competes.

Sebo MEC's enterprise value of approximately 150 billion KRW (~$113M USD) places it as a small-cap KOSDAQ-listed contractor. The mismatch between revenue scale and headcount (51-100 employees) implies a contract-and-subcontract operating model, where direct labor is lean and execution relies on subcontracted trade partners — a common structure in Korean project-based construction. The company shows no disclosed AI/ML positioning, no foreign expansion activity, and no M&A activity in the available data.
