TSB: Modest calibrated valuation gap amid weak profitability and forensic risk
The calibrated intrinsic value is VND 17,118 versus the current price of VND 16,000, a calibrated gap of 7.0% that is illustrative and not a forecast return.
Business Overview
Công ty Cổ phần Ắc quy Tia Sáng is a Vietnamese battery company listed on HNX in the electronics and electrical equipment sector. The available data do not break out products, customers, or segment economics, limiting assessment of its competitive position and exposure to particular end markets.
TSB is controlled by listed chemical group DGC, which owns 51.0% of the shares. Under VAS 25, ownership above 50% constitutes control. This may provide a strategic parent relationship, but the available information does not establish the extent of operational or financial support. The concentrated ownership also means minority shareholders have limited influence over corporate decisions.
Key points
Revenue increased from VND 157.5 bn in 2023 to VND 192.3 bn in 2025, but earnings have not followed that trajectory: net profit fell from VND 5.2 bn in 2024 to VND 2.1 bn in 2025. Latest ROE is 2.7%, net margin is 1.1%, and EBIT margin is 0.9%, indicating limited profitability relative to the current valuation multiples of 51.5x P/E and 17.1x EV/EBITDA.
The calibrated intrinsic value of VND 17,118 is 7.0% above the current price of VND 16,000. This is an illustrative estimate from an earlier version of the back-test, provided only for comparison with the last close; it is not a forecast, does not establish mispricing, and should not be interpreted as an investment opportunity. With earnings having weakened despite revenue growth, the key question is whether margins can recover sustainably.
The balance sheet indicators are not uniformly adverse: debt/equity is 0.46x, and three-year operating cash flow to net profit is 1.27x, around the 55.8th percentile versus Vietnamese peers. However, earnings quality is 30.5/100 and the Beneish M-Score risk assessment is moderate, warranting caution around reported earnings. The 4.4% dividend yield offers income support, but the available data do not provide a payout history or establish its sustainability.
Valuation Commentary
The supplied comparison uses an EV/EBITDA approach based on mid-cycle EBITDA. The calibrated intrinsic value is an illustrative estimate from an earlier version of the back-test, intended only for comparison with the last close.
- Calibrated intrinsic value of VND 17,118 versus a current price of VND 16,000.
- The supplied calibrated gap is 7.0%; it is not a forecast return or evidence of mispricing.
- Latest EV/EBITDA is 17.1x, while P/E is 51.5x.
- 2025 net profit was VND 2.1 bn, down from VND 5.2 bn in 2024, despite revenue growth over the three-year period.
The calibrated gap is a comparison with the last close, not a forecast return or a basis for concluding that the shares are mispriced. No validated track record exists for this estimate, and no model reliability assessment or outperformance probability is supplied; the weak latest profitability adds material uncertainty.
Points in favour
- Revenue grew from VND 157.5 bn in 2023 to VND 192.3 bn in 2025.
- Three-year operating cash flow to net profit was 1.27x, at the 55.8th percentile versus Vietnamese peers.
- Debt/equity of 0.46x is below one times equity.
- The latest dividend yield is 4.4%, although its sustainability cannot be assessed from the available data.
Points against
- Net profit declined to VND 2.1 bn in 2025 from VND 5.2 bn in 2024, while revenue reached VND 192.3 bn.
- Latest ROE is 2.7%, net margin 1.1%, and EBIT margin 0.9%, indicating thin returns and operating profitability.
- Latest P/E of 51.5x and EV/EBITDA of 17.1x leave valuation sensitive to continued earnings weakness.
- The M-Score risk level is moderate, with a Vietnamese-peer percentile of 84.7 and a year-on-year increase of 1.5719.
- DGC controls 51.0% of TSB, concentrating voting power and limiting minority influence.
Sector Context
TSB is classified in the cyclical sector and in electronics and electrical equipment. Its revenue expanded over 2023–2025, but the 2025 decline in net profit highlights the importance of margins and earnings resilience in evaluating a cyclical manufacturer. The supplied data do not include peer margins, demand indicators, or input-cost information, so relative operating performance and cycle position cannot be established.
As an HNX-listed Vietnamese company, TSB is subject to local disclosure and listing requirements. No supplied figures indicate that it meets any of the stated statutory cancellation tests: accumulated losses are 0.0 times paid-in capital, consecutive net-loss years are 0, and equity excluding minority interests is not negative. These observations do not imply any exchange decision. DGC’s 51.0% holding constitutes control under VAS 25; the data do not establish whether this relationship produces operating or financing benefits for TSB.
Risk Factors
- Earnings deterioration: net profit fell from VND 5.2 bn in 2024 to VND 2.1 bn in 2025, despite revenue increasing to VND 192.3 bn.
- Thin profitability: latest EBIT margin is 0.9% and net margin is 1.1%, leaving earnings exposed to modest changes in costs or sales mix.
- Valuation sensitivity: P/E is 51.5x and EV/EBITDA is 17.1x against low latest ROE of 2.7%; the supplied calibrated gap does not establish valuation support.
- Forensic concern: M-Score risk is moderate, its peer percentile is 84.7, and it increased by 1.5719 year on year. The score is a screening signal, not proof of manipulation.
- Earnings-quality uncertainty: the earnings-quality score is 30.5/100, despite three-year operating cash flow to net profit of 1.27x.
- Ownership concentration: DGC controls 51.0% of the shares, potentially limiting minority shareholders’ influence over governance and capital allocation.
- Cyclicality: the sector classification and decline in 2025 profit make earnings durability and recovery uncertain; no segment or demand data are provided to assess the cycle.
What could change the picture
- A recovery in net profit from the 2025 level of VND 2.1 bn could improve the earnings case, but the available data provide no forward guidance.
- Sustained revenue growth beyond the VND 192.3 bn recorded in 2025, accompanied by margin improvement, would help demonstrate operating leverage.
- Future disclosures clarifying the drivers of the moderate M-Score risk and the low earnings-quality score could reduce uncertainty.
- Evidence that the 4.4% dividend yield is supported by recurring cash generation could strengthen the income case.
Forensic Assessment
The Beneish M-Score is -1.2115, assessed as moderate risk, at the 84.7th percentile versus Vietnamese peers and up 1.5719 year on year. The conventional -1.78 cutoff was developed using a 1980s US sample and is crossed by a larger share of Vietnamese companies; the score should therefore be interpreted with its peer ranking and change, not as evidence of manipulation. Earnings quality is 30.5/100. Three-year operating cash flow to net profit is 1.27x, while receivables outside the trade cycle are 0.6% of assets, at the 26.4th percentile versus Vietnamese peers.
DGC’s 51.0% stake creates concentrated ownership. No insider or related-party trade registrations were recorded in the supplied 12-month window; registrations are not executed trades. The supplied listing-test indicators show no accumulated losses, no consecutive net-loss years, and no negative equity excluding minority interests, so none of those tests is met on the figures provided.
Track Record
No validated track record or hit rate is supplied for the calibrated intrinsic value. The calibrated estimate is explicitly an illustrative comparison from an earlier version of the back-test, not a validated forecast; its 7.0% gap should therefore be treated with caution. Model reliability and the probability of outperforming sector peers are unavailable.
