CH. Karnchang (CK) and STECON are both exposed to major construction projects, but they are not identical contractor-only businesses. CK combines contracting with infrastructure investments; STECON is a holding company spanning construction, utilities and power, and logistics and transportation. Their financial results are only meaningfully comparable when the reporting period and business perimeter match.
How the businesses are structured
| Company | Business structure | What that means for comparison |
|---|---|---|
| CH. Karnchang (CK) | The Stock Exchange of Thailand describes CK as a general contractor for government agencies, state enterprises, and private entities that also invests in comprehensive infrastructure development. Its annual report discusses investments intended to generate dividends or share of profit. | Construction contracts are only part of CK’s economic exposure; infrastructure investments can also contribute income. SET CK Factsheet; CK Annual Report 2024. |
| STECON Group | STECON is a holding company whose core businesses include construction contracting, utilities and power, and logistics and transportation. Its listed holding-company structure was established in 2023 and listed on the SET in place of Sino-Thai Engineering in 2024. | Its results encompass a broader group perimeter than a standalone construction contractor. The company describes construction work across infrastructure, buildings, energy, industry, and environment. SET STECON Factsheet; STECON 6M 2026 Listed Company Snapshot. |
What the available financial figures show
STECON’s SET snapshot table reports revenue of THB 17,592.87 million and net profit of THB 1,261.79 million for the six months ended 30 June 2026. The same table gives 6M 2025 comparatives of THB 15,993.62 million revenue and THB 853.60 million net profit.

| STECON, SET snapshot table | 6M 2025 | 6M 2026 |
|---|---|---|
| Revenue | THB 15,993.62 million | THB 17,592.87 million |
| Net profit | THB 853.60 million | THB 1,261.79 million |
The snapshot’s narrative gives different 6M 2026 totals—THB 17,574.9 million revenue and THB 1,258.3 million net profit—than its financial table. The figures above use the table basis; the discrepancy should not be silently blended into a single value. The company attributes higher first-half construction contract revenue mainly to data center and clean energy projects. These are STECON figures, not a direct comparison with CK: CK’s available filing index confirms 2Q 2026 statements and management discussion, but comparable CK values are not established here. Consult CK’s quarterly results and STECON’s resource center for their filings, then align reporting period, consolidated basis, and business perimeter before comparing revenue, profit, margins, or cash flow.
Projects and backlog: use the date and definition
CK’s 2024 annual report records several contracts with Bangkok Expressway and Metro, including civil and mechanical-and-electrical work for the MRT Orange Line and additional Blue Line rolling stock and systems. One example is the CKST-OR joint operation with Sino-Thai Engineering for Orange Line civil works. CK held 51% under the agreement; the report gives the contract value as THB 58.95 billion including VAT and an approximate duration of 64 months. These are 2024 contract disclosures, useful for understanding project scale and collaboration, not proof of current project status.
#1 Best Overall
The same report states CK Group backlog pending revenue recognition was THB 209,968 million at 31 December 2024, and expected to contribute to revenue growth over the following three years. This is a dated year-end 2024 measure—not CK’s current 2026 backlog. It should not be ranked against a STECON backlog figure unless the date and definition match.
Diversification and recurring-income plans
CK: construction plus infrastructure interests
CK’s annual report describes a focus on transport and communications infrastructure and investments that can provide longer-term dividends or share of profit. At year-end 2024, it reported CK Group shareholding of 37.18% in Bangkok Expressway and Metro and a 20% interest in Luang Prabang Power Company. Those dated disclosures help explain why CK’s economics can extend beyond contract revenue; they do not establish the present value or current status of those holdings.
Rank #2
STECON: stated expansion priorities
STECON identifies construction across infrastructure, buildings, energy, industry, and environment. Its 6M 2026 snapshot says it is exploring utilities, energy, data centers, water, and logistics, with a stated aim of developing recurring income and entering growth businesses. Treat these as company-stated priorities, not evidence that every prospective investment has been implemented.

Fixed-price construction contracts can leave a contractor exposed when materials, labor, energy, or transport costs rise. STECON’s 6M 2026 snapshot specifically discusses input-cost volatility and its mitigation approach. For either company, project mix, contract duration, execution, and cost control matter alongside headline revenue. For an investor comparing results, backlog dates and definitions, consolidated reporting boundaries, and the contribution of non-construction investments also affect what the numbers mean.
