To assess CH. Karnchang Public Company Limited (SET: CK), use its dated financial statements and One Report for reported results, and treat backlog figures from securities analysts as estimates unless the company reports them directly. The company reported 2025 revenue of THB 45,535.69 million and net profit of THB 3,328.22 million; the most recent backlog estimate identified here is DAOL Securities’ roughly THB 190 billion estimate as of September 2025—not a current company-reported figure.
Start with the issuer’s reported financial results
CH. Karnchang is a Thai construction and infrastructure company listed on the Stock Exchange of Thailand as CK. Its disclosed activities include general contracting for government agencies, state enterprises, and private entities—as a main contractor, subcontractor, joint venture (JV), or consortium—as well as infrastructure investment. The SET factsheet classifies CK under Construction Services and summarizes those activities: SET CK factsheet.
For actual results, begin with CK’s investor-relations resource center and financial statements, then check the Thai SEC’s CK filings index. CK lists its 2025 Form 56-1 One Report, 2025 financial statements and annual MD&A, and 2026 quarterly materials. The SEC index lists 2025 annual statements and reviewed company and consolidated statements for Q1 and Q2 2026. The SET also hosts issuer announcements.
CK’s financial-highlights page reports the following figures. Keep the period and metric attached whenever quoting them:

| Reporting period | Revenue | Net profit | Source |
|---|---|---|---|
| Full year 2025 | THB 45,535.69 million | THB 3,328.22 million | CK financial highlights |
| Full year 2024 | THB 38,769.91 million | THB 1,445.90 million | CK financial highlights |

Use the statements and notes to establish what each revenue figure includes and whether it is consolidated, construction-only, or includes investment-related activity. Do not infer the accounting definition from a highlights page alone. The company’s resource center is at CK investor-relations downloads; the SEC filings index is at Thai SEC financial statements; and SET issuer announcements are at SET news and announcements.
Separate reported backlog from analyst estimates
Backlog is useful as an indicator of work potentially available to recognize as revenue, but its value depends on the reporting date, definition, and CK’s attributable share. The latest figure identified here is not an issuer-reported value: a DAOL Securities company update dated 22 September 2025 estimated CK backlog at about THB 190 billion. The same note described a 2024 peak of about THB 210 billion and estimated that backlog could support revenue for at least four to five years. Those are DAOL’s dated estimates, not a current company forecast or a guarantee of future results. See the DAOL Securities research page.

CK lists a 2025 One Report and annual MD&A, but the available listing does not establish a year-end backlog figure or how CK defines backlog. Before quoting a newer official number, locate the full 2025 One Report and reconcile it with any current investor presentation or exchange filing. The relevant CK document listing is CK investor-relations downloads.
When comparing backlog figures, check whether the company counts only signed contracts or also awarded-but-unsigned work, how it treats JV and consortium projects, what commitments are included, and whether the number reflects the full project value or CK’s share. Record the date and definition alongside the total. Even a large backlog is not guaranteed revenue, profit margin, or cash flow: work can be delayed, scope and attributable value can differ, and revenue recognition and cash collection occur on their own schedules.

Evaluate project exposure one contract at a time
DAOL’s September 2025 note linked margin expectations to CK’s project mix and progress. It named the Orange Line, South Purple Line, Den Chai–Chiang Rai–Chiang Khong double-track railway, and Luang Prabang hydropower works as projects progressing at that point. It also identified future progress on the Double Deck expressway and South Purple Line as possible 2026 catalysts. These are dated analyst descriptions and expectations, not confirmation of current status. For current claims about awards, approvals, progress, or schedules, verify them against CK or relevant government primary disclosures.
For each material project, build a dated record using these checks:

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
- Contract certainty: Is there a signed contract, an award, a memorandum, or only an expected opportunity?
- Ownership and scope: What work is CK responsible for, what is its attributable share, and is delivery through a JV or consortium?
- Execution: What progress and schedule are disclosed? Are approvals, land access, or interfaces with other contractors potential dependencies?
- Economics: What is known about expected margin and cost pressure, and how does the project mix affect gross margin?
- Conversion: When is work expected to be completed, recognized as revenue, billed, and collected in cash?
This project-level view helps explain why a backlog total may not convert evenly into revenue, earnings, or cash generation. The DAOL update provides a dated view of project mix, progress, and margin considerations; it is not a substitute for current contract-level disclosures.

A practical source-checking workflow
- Open CK’s investor-relations downloads. Find the 2025 Form 56-1 One Report, annual MD&A, financial statements, and the latest quarterly materials. Start at CK investor-relations downloads.
- Verify the reporting period and entity basis. Check whether the figure is annual or interim and whether it refers to CK’s company-only or consolidated statements. Read the notes for the revenue definition and any investment-related components.
- Cross-check the filing. Match the period against the Thai SEC’s CK financial-statement index and the SET’s announcements: SEC financial statements and SET news and announcements.
- Find the official backlog definition and date. In the full One Report, MD&A, or current presentation, record the stated total, the measurement date, what qualifies as backlog, and how JV or consortium shares are handled.
- Check project disclosures individually. Confirm contract status, scope, CK’s share, progress, schedule, dependencies, and any stated economics using current company or government disclosures. Keep analyst commentary clearly labeled and dated.
How to present the findings without overstating them
- Label company-reported financial results by period and metric; distinguish annual from interim figures.
- Call the approximately THB 190 billion figure a DAOL estimate as of September 2025, not CK’s current reported backlog.
- Do not describe a project as awarded, active, delayed, or completed based only on the dated analyst note.
- Do not treat backlog as a forecast of profit or cash receipts; explain contract scope, execution, margin, and conversion timing separately.
