PYN Elite Books EUR 150M on STB, Trims Stake to 17.9% on 20% Cap

Overview

PYN Elite, a long-standing Finland-domiciled fund focused on Vietnamese equities, disclosed in its 26 September investor letter that cumulative gains on Sacombank (STB) have passed EUR 150 million, equivalent to more than VND 4,600 billion. The fund trimmed the position because internal rules cap any single holding at 20% of the portfolio, leaving STB as its largest position at 17.9% as of 16 September. The same letter sets out large banking weights in VIB and OCB, making the sector roughly 28% of the fund.

Key Facts

• Cumulative profit on STB since first purchase in November 2022: over EUR 150 million, or more than VND 4,600 billion.
• Realized gains from partial STB sales: approximately EUR 65 million, or close to VND 2,000 billion.
• STB portfolio weight at 16 September: 17.9%, the fund’s largest single holding, against a 20% internal cap.
• PYN forecasts STB net profit of about VND 6,160 billion in 2026, over VND 20,300 billion in 2027 and nearly VND 29,800 billion in 2028.
• VIB weight: 5.3%, with forecast net profit of VND 8,873 billion (2026), VND 13,549 billion (2027) and VND 17,606 billion (2028).
• VIB’s 10-year partnership with Visa, signed January 2026, is valued by PYN at USD 650 million, or roughly VND 17,000 billion.
• OCB weight: 4.8%; the three bank holdings together account for about 28% of the portfolio.

What Happened

In the letter to investors dated 26 September, PYN Elite said Sacombank has been one of its most successful Vietnamese investments. The fund began buying STB in November 2022 and has since realized about EUR 65 million of profit while retaining a 17.9% weight, trimmed from higher levels because internal rules prohibit any single stock from exceeding 20% of the portfolio. PYN noted that Sacombank’s trailing 12-month reported profit fell roughly 84% while the share price rose 31% over the same period, attributing the earnings decline to additional provisioning rather than to the core franchise, which it says has improved.

The letter also flagged Sacombank’s leadership changes, with Nguyen Duc Thuy, widely known as bau Thuy, now Permanent Vice Chairman of the board after previously running the bank as General Director. On VIB, PYN said the bank signed a special cooperation agreement with Visa from January 2026 under which it receives a fixed annual payment tied to customer-base expansion, with the total deal value stated at USD 650 million over 10 years. PYN expects VIB to return to profit growth as provisioning pressure eases and sees scope for partial reserve write-backs. OCB is held at 4.8%.

Market Context

STB trades on HOSE and closed at VND 77,200 on 28 September 2026, a level that reflects the 31% year-to-date advance PYN references even as reported earnings contracted. VIB, also on HOSE, closed at VND 13 with volume of 4,088,000 shares, down 1.87% on the session, while OCB closed at VND 10,100. The disclosure lands in a Vietnamese banking sector where earnings are bifurcated: headline profits are depressed by legacy provisioning, particularly among banks still working through restructured assets, while core pre-provision operating performance and credit demand have held up.

Strategic Significance

For long-term holders, the letter frames STB as a provisioning-cycle story rather than an earnings-momentum story: the fund’s 2026-2028 profit path implies a step-change once legacy charges are absorbed, which is the basis for tolerating an 84% trailing profit decline alongside a 31% price gain. The 20% cap also creates a mechanical constraint that will force further trimming if STB outperforms the rest of the book, meaning position-size disclosures should be read as a function of the rule rather than as a change in conviction. VIB’s Visa arrangement is the more unusual item, since a fixed annual payment tied to customer acquisition converts part of the retail banking franchise into a contracted revenue stream, which matters for how the market values fee income versus credit spread. The 28% aggregate bank weight concentrates the fund in a single policy-sensitive sector.

What to Watch

• Sacombank quarterly filings for the pace of provisioning charges and any reversal, which determines whether the 2026 profit forecast of VND 6,160 billion is reachable.
• PYN’s next monthly or quarterly letter for any further change to the STB weight relative to the 20% cap.
• VIB disclosures on the Visa agreement, including the annual fixed payment amount and the customer-growth metric it is tied to.
• OCB’s provisioning and asset-quality reporting, given its 4.8% weight and limited detail in the letter.
• Any State Bank of Vietnam policy or credit-growth guidance affecting the banking sector’s 2026-2027 earnings trajectory.
