YBM: small-cap mining with leverage and limited upside after mid-cycle EV/EBITDA calibration
Intrinsic value VND 9,485 vs market price VND 9,900 -> implied downside -4.2% (model confidence: very_low).
Tổng quan doanh nghiệp
Công ty Cổ phần Khoáng sản Công nghiệp Yên Bái (YBM) is a HOSE-listed industrial minerals and mining company operating in the 'Khai khoáng' segment. The company generated revenue of VND 875.8 bn in 2025, up from VND 770.8 bn in 2024 and VND 553.7 bn in 2023, indicating cyclical recovery in product demand. Its asset base has expanded to VND 714.0 bn in 2025 (from VND 564.8 bn in 2023).
Luận điểm đầu tư
YBM trades at a low market multiple relative to broader sector history: EV/EBITDA reported at 5.94x while our sector_ev_ebitda is 9.14x and our calibrated fair_ev_ebitda is 6.89x (own_history). The company reported ROE of 14.2% and ROA of 4.3% (latest), with gross margin at 36.3% and an EBIT margin of 6.0%, showing operating profitability but limited conversion to net profit (net profit margin 3.3%).
Leverage is a material structural constraint: Debt/Equity stands at 2.31x and net_debt in the valuation model is VND 336,135,407,656, which suppresses equity value in our EV/EBITDA mid-cycle model. Free-float and liquidity are limited (avg_volume_2w 1,509 shares, foreign_room 0.0%), increasing execution and exit risk for larger investors. The model produces an intrinsic value of VND 9,485 per share versus the match price of VND 9,900 (implied -4.2%), and the model confidence is very_low after isotonic calibration and recalibration steps.
Given the narrow implied downside/upside (within single digits) combined with very_low model confidence, concentrated insider ownership (top shareholder stakes: 23.4%, 23.0%, 10.8%, 9.2%, 7.9%) and low trading liquidity, the risk-reward is unattractive for buyers seeking price appreciation. However, the company benefits from improving revenues (2025 revenue VND 875.8 bn) and delivered a higher net profit in 2025 (VND 28.6 bn) versus 2024 (VND 13.3 bn), which supports operational recovery optionality.
Diễn giải định giá
EV/EBITDA mid-cycle: we apply a mid-cycle EBITDA (own_median over 7 years) multiplied by a calibrated fair EV/EBITDA multiple and subtract net debt to derive equity value per share.
- mid_cycle_ebitda = VND 54,332,440,047 (model input)
- fair_ev_ebitda = 6.89x (own_history calibration) vs sector_ev_ebitda = 9.14x
- net_debt = VND 336,135,407,656 is deducted from enterprise value
- EBITDA coefficient of variation = 0.2328 (moderate cyclicality) and 7 years of data used
- calibration method = isotonic; raw_intrinsic_value prior to calibration = VND 1,185 per share
The resulting intrinsic value of VND 9,485 per share implies a small price gap versus the current market price (down -4.2%). Confidence in the calibrated estimate is very_low due to illiquidity and model sensitivity to net debt and EV/EBITDA choice; treat the valuation as directional rather than precise.
Các luận điểm cần cân nhắc
- Revenue recovery: revenue expanded from VND 553.7 bn (2023) to VND 875.8 bn (2025), supporting higher EBITDA potential.
- Operating margins are reasonable for the sector: gross margin 36.3% and EBIT margin 6.0%, providing buffer if commodity prices improve.
- ROE of 14.2% indicates the company can generate returns on equity despite heavy leverage, supporting upside if leverage is reduced or earnings continue to grow.
- High leverage: Debt/Equity 2.31x and model net_debt VND 336,135,407,656 materially depresses equity value and increases downside in a downturn.
- Liquidity and foreign access constraints: avg_volume_2w only 1,509 shares and foreign_room 0.0% make meaningful position entry/exit difficult and amplify price impact.
- Valuation calibration weak: model confidence very_low, raw_intrinsic_value before calibration was only VND 1,185 per share, signalling sensitivity to methodological choices.
- Concentrated ownership: two large shareholders hold ~46.4% combined (23.4% + 23.0%), which can limit free-float and corporate governance flexibility.
Bối cảnh ngành
YBM sits in the cyclically exposed Vietnamese mining sector ('Khai khoáng'), where revenue and EBITDA are sensitive to commodity cycles and construction demand. Sector median metrics show higher EV/EBITDA (sector_ev_ebitda 9.14x) than YBM's current EV/EBITDA of 5.94x, suggesting either a valuation gap or firm-specific weaknesses. Regulatory context: state-driven credit growth quotas from SBV and periodic tightening can affect capex and working capital financing for miners; similarly, SOE-related mandates and VAS accounting treatment for mining reserves and depreciation can create comparability issues vs IFRS peers. Land use rights are less central for hard-rock mineral miners than for real estate, but permitting and reserve recognition under VAS remain a local forensic focal point.
Yếu tố rủi ro
- High financial leverage (Debt/Equity 2.31x) increases refinancing and interest-rate risk in a tightening environment.
- Model and data uncertainty: valuation confidence is very_low and the calibrated result is sensitive to the chosen fair_ev_ebitda (6.89x) vs sector (9.14x).
- Low liquidity and zero foreign_room constrain marketability and increase execution risk for larger asset allocations (avg_volume_2w 1,509).
- Ownership concentration: top two shareholders hold ~46.4%, reducing free-float and raising correlated governance risk.
- Earnings volatility from commodity cycles: EBITDA CV 0.2328 and cyclical revenue history (revenue growth YoY 13.7% in latest) can swing profitability.
- No dividend yield (0.0%) reduces income appeal for yield-seeking investors.
Yếu tố có thể tác động
- Acceleration of EBITDA through higher commodity/contract prices or higher utilization, which would lift mid-cycle EBITDA above the model input VND 54,332,440,047.
- Material debt reduction or refinancing that improves net_debt profile (current model net_debt VND 336,135,407,656).
- Improved liquidity or loosening of foreign ownership limits (foreign_room currently 0.0%) that could reprice the stock closer to sector multiples.
Đánh giá dấu hiệu kế toán
No Beneish M-Score available (mscore null) and no explicit forensic red_flags in the input. Earnings quality is moderately high at 71.7/100, which suggests reported earnings are not obviously manipulated by standard heuristics. Nevertheless, the model flagged 'manipulation_risk' and 'illiquid' in sanity_flags during calibration; given concentrated insider ownership and low trading liquidity, governance and disclosure quality merit continued monitoring.
Lịch sử định giá
The model's historical record spans 9 years (first_year 2018, last_year 2026) with a hit_rate of 0.5, meaning roughly 50% of the time directional calls exceeded the >10% threshold and matched subsequent price moves. The average historical upside across calls was 10.6% (avg_upside_pct 10.5756%), but the modest hit rate suggests limited predictive reliability; treat model signals as one input among qualitative assessments rather than a standalone decision driver.
