Tổng Công ty Sông Đà (SJG): State-owned construction group with cyclical earnings rebound but limited public float and low confidence in model
Intrinsic value VND 24,678 vs market VND 22,000 — implied upside 12.2% (model confidence: low).
Tổng quan doanh nghiệp
Tổng Công ty Sông Đà (SJG) is a state-controlled construction and engineering group listed on UPCoM active in construction contracting and materials under ICB 'Xây dựng và Vật liệu'. The company reported revenue of VND 6,620.8 bn and net profit of VND 1,696.4 bn in 2025, and total assets of VND 22,521.2 bn at year-end 2025. Ownership is heavily concentrated: the state investor 'Tổng Công ty Đầu Tư Và Kinh Doanh Vốn Nhà Nước' holds 99.79% of shares.
Luận điểm đầu tư
The investment case rests on a cyclical recovery in construction activity reflected in a strong 2025 earnings print: net profit rose to VND 1,696.4 bn in 2025 from VND 613.7 bn in 2024, supporting an ROE of 24.1% and an EBITDA multiple below the model's fair multiple. Valuation implied by an EV/EBITDA of 8.2 versus the model's fair EV/EBITDA of 9.85 results in an intrinsic value of VND 24,678 per share, implying 12.2% upside to the current price of VND 22,000. Operational profitability metrics are reasonable for the sector: EBITDA/EBIT margins convert to an EBIT margin of 14.7% and a gross margin of 20.7%; P/E is 5.2 and P/B is 1.16 based on BVPS of VND 16,748 per share.
However, the case is constrained by structural liquidity and governance features: trading is very thin (avg volume two weeks: 295 shares) and foreign ownership room is 0.0%, limiting demand from foreign investors. State ownership at 99.79% means free float and potential corporate actions are effectively controlled by the SOE parent; this also raises questions about dividend and capital allocation flexibility given typical SOE payout/mandate dynamics. Finally, the valuation model's confidence is low, reducing conviction in the VND 24,678 target despite an above-sector-median implied upside (sector median upside: 9.6%).
Diễn giải định giá
EV/EBITDA mid-cycle approach: apply a fair EV/EBITDA multiple to our mid-cycle EBITDA and subtract net debt to derive equity value per share.
- Fair EV/EBITDA multiple: 9.85 (own_history).
- Reported enterprise multiple: EV/EBITDA 8.20 (ratios_latest).
- Earnings rebound: net profit VND 1,696.4 bn in 2025 (financials_3yr_bn_vnd).
- High state ownership and near-zero foreign room constrain market-implied value and liquidity.
The model yields an intrinsic value of VND 24,678 per share (implied upside 12.2%) but model confidence is low; the result should be treated as indicative rather than precise. Given low liquidity, heavy state ownership and the recalibrated low confidence, execution and marketability risk limit conviction even though headline multiples look undemanding.
Các luận điểm cần cân nhắc
- Net profit jumped to VND 1,696.4 bn in 2025 from VND 613.7 bn in 2024, indicating a strong recovery in margins and project execution.
- ROE of 24.1% and P/E of 5.2 suggest the market is not pricing sustainable profitability at current levels.
- EV/EBITDA of 8.2 is below our fair EV/EBITDA of 9.85, leaving room for multiple expansion if visibility on mid-cycle EBITDA improves.
- Free float is effectively nil: state shareholder holds 99.79%, and foreign_room is 0.0%, limiting demand and tradability.
- Liquidity is very low (avg volume two weeks: 295 shares) and the UPCoM listing reduces visibility to institutional buyers.
- Valuation model confidence is low and the model has 'illiquid' sanity flag, so the intrinsic value is uncertain despite a 12.2% implied upside.
Bối cảnh ngành
The construction and building materials sector in Vietnam is cyclical and heavily influenced by public infrastructure and real estate activity; SBV credit growth quotas and state budget disbursement timing materially affect orderbooks and working capital for contractors. Peers show mixed outcomes: sector median implied upside from our coverage is 9.6%, and some names in the peer set show higher upside potential (examples: BCR +39.2%, DDB +30.2%). For state-controlled contractors like SJG, SOE governance and payout mandates matter — state owners often determine dividend policy and asset transfers. In addition, VAS accounting and the prevalence of long receivable cycles mean earnings volatility can be masked; construction firms frequently carry non-cash items such as land use rights or long-term progress receivables that require forensic scrutiny.
Yếu tố rủi ro
- Extremely concentrated ownership: state investor holds 99.79%, reducing free-float and limiting minority shareholder influence.
- Very low liquidity (avg volume two weeks: 295), increasing execution risk for large trades and widening realized bid-ask costs.
- Model confidence is low and the valuation flagged as 'illiquid', so intrinsic value has elevated estimation risk.
- Sector cyclicality: reliance on public spending and real-estate cycles can cause sharp revenue and margin swings; revenue fell in 2024 (VND 5,531.4 bn) then rose in 2025 (VND 6,620.8 bn).
- Zero foreign ownership room (0.0%) prevents offshore demand re-rating and limits potential investor base expansion.
- No dividend yield reported (0.0%), so total return depends on price appreciation rather than cash payout.
Yếu tố có thể tác động
- Improved visibility on mid-cycle EBITDA or confirmed multi-year orderbook that supports the fair EV/EBITDA multiple of 9.85.
- Regulatory or corporate actions that increase free float or allow foreign ownership — any relaxation would likely re-rate the stock.
- Quarterly/annual results that sustain the 2025 margin levels and show recurring earnings power.
Đánh giá dấu hiệu kế toán
No Beneish M-Score or other forensic flags are provided and the "red_flags" array is empty. Earnings quality score is 62.9, which is moderate and suggests some caution but no clear manipulation signals in the supplied data. Given inherent VAS differences in revenue recognition for construction contracts and the company's state ownership, monitor receivables, contract margins and one-off items in future filings.
Lịch sử định giá
The model's historical track record shows 9 years with a hit rate of 87.5% and an average realized upside of 121.2% over the sample. While this track record is strong, the current model confidence is low and the stock is flagged as illiquid; past performance is informative but does not eliminate present execution and liquidity constraints.
