Anyone valuing a Thailand M&A deal in Q3 2026 is working against an unusual backdrop: a public market that just re-rated sharply, a politically calmer Thailand, and a wide spread of trading comparables across industries that don’t all move the same direction. This guide walks through what the current SET-listed comparables imply for private-company valuation in Thailand, and how to adjust public multiples into a defensible private valuation.
Thailand’s public markets have had a strong run in 2026. The SET Index is up roughly 28% year-to-date, political risk has genuinely receded, and the macro backdrop has stabilized after a difficult few years. For business owners and investors thinking about a transaction — a sale, a capital raise, or an acquisition — the natural question is whether that market strength should translate into higher valuations for private Thai companies too.
Our Q3 2026 valuation guidance, drawn from a synthesis of macroeconomic research, equity market data, and trading comparables across the SET-listed universe, points to a more measured answer: the easy gains from de-risking are behind us. Multiples, discount rates, and growth assumptions applied to Thai targets this quarter should reflect normalization, not acceleration.
Key takeaways:
- The SET’s ~28% YTD rally has been driven by multiple expansion (political risk premium collapsing), not earnings growth — at ~14x forward P/E ex-electronics, further re-rating needs earnings confirmation.
- Trading comparables by industry range from ~8x to over 100x P/E — read them industry-by-industry, not off a blended market average.
- The direction between LTM and FY1 multiples matters more than the level: it tells you whether the market is pricing in growth or a pullback.
- Public multiples need three adjustments — earnings normalization, multiple selection, and marketability/control/size discounts — before they translate into a private Thailand business valuation.
Here’s what that means in practice.

NM = not meaningful (negative or de minimis earnings). Averages are simple, equal-weighted averages of the listed constituents in each industry. Public multiples require adjustment (marketability, control, size, normalization) before application to private-company valuation — see full guidance report.
The Macro Picture: Steadier, Not Stronger
Thailand’s 2026 GDP growth is expected to land around 1.8%, weighed down by elevated energy prices and US tariff exposure on manufacturing. The recovery path improves from there — 2.6% in 2027, averaging 3.2% across 2028–30 — but it’s an uneven one. Tech-linked exports (electronics, hard disk drives, integrated circuits, AI-supply-chain components) are running well ahead of the rest of the economy, while autos, petrochemicals, and furniture continue to face structural competitiveness pressure rather than a purely cyclical dip.
Inflation is expected to stay within the Bank of Thailand’s 1–3% target band, and the BOT is expected to hold its policy rate at 1.00% through 2026, with a modest easing bias opening up in 2027. The baht is forecast to trade in a Bt30–34:US$1 range — cross-border deal models should stress-test both ends of that range rather than anchoring on a single spot assumption.
On the political side, the February 2026 election delivered the Bhumjai Thai Party a decisive mandate, and the resulting coalition is expected to serve a full term through 2030. Independent assessments now put the probability of a coalition-destabilizing policy misstep below 20%, and another military coup below 10%. Both are meaningful improvements — but not zero, and not something to price as a permanent state of affairs.
Why the Easy Gains Are Behind Us
The SET’s 28% rally this year has been driven mainly by multiple expansion — a collapsing political risk premium and capital rotating in from elsewhere in the region — rather than earnings growth. At roughly 14x forward P/E (excluding the single dominant electronics name), the market sits at the mid-point of its historical 13–16x range given 2–3% GDP growth and 7–9% earnings growth. In other words, the re-rating has largely run its course. Further upside from here requires earnings to actually show up, and that confirmation remains uncertain through the second and third quarters of 2026 as energy-shock and inventory distortions work their way through reported results.
For deal purposes, this matters: the temptation to extrapolate 2026’s market strength into 2026 deal multiples is one we’d caution against. The multiple expansion already happened. What comes next depends on earnings delivery, not further sentiment improvement.
Thailand Trading Comparables by Industry: Why Direction Matters More Than the Level
Our Thailand trading comparables cover the SET-listed universe across 13 industries, viewed on both a trailing (LTM) and forward (FY1) basis. The single most useful signal in the data isn’t the level of any given multiple — it’s the direction between LTM and FY1.
Where the forward multiple sits meaningfully below the trailing one, the market is pricing in real earnings or EBITDA growth. That shows up clearly in Telecom/ICT (on both P/E and EV/EBITDA) and Electronics. Where the forward multiple sits above the trailing one — Construction, Real Estate & Materials, and Transportation & Tourism on P/E, and Media dramatically so — the market is instead pricing in a near-term earnings pullback from an unusually strong trailing base. That’s the opposite of what the headline multiple alone would suggest, and it’s exactly the kind of detail that gets lost if you apply a single blended multiple across a comp set.
A few other patterns stand out:
Electronics trades at a clear premium across every metric — P/E moving from 91.7x (LTM) to 55.5x (FY1), EV/EBITDA from 40.3x to 30.8x, P/BV from 11.3x to 10.0x. This reflects one dominant AI-supply-chain bellwether, not a sector-wide re-rating. Strip that name out and the rest of the market clusters in far more conventional ranges: P/E roughly 8x–28x, EV/EBITDA roughly 6x–21x, and P/BV mostly 1x–3x.
P/BV is the most stable multiple across the LTM-to-FY1 shift, which makes sense since book value moves slowly. It’s also the best lens for separating genuinely asset-light, high-ROE sectors (Electronics, Telecom/ICT, both trading in double-digit P/BV) from capital-intensive sectors simply trading near book (Banking, Finance, Energy & Utilities, Real Estate & Materials, all clustered around 1.1x–1.2x).
Financial-sector names — Banking, Finance, Insurance — are the cheapest and most stable across every metric, consistent with mature, well-capitalized, low-growth businesses. Insurance’s P/BV slipping from 1.0x to a forward discount of 0.8x is the one break from that stability and worth a closer look for anyone valuing an insurance-adjacent target.
The practical takeaway: select the multiple by what actually drives the sector’s economics. EV/EBITDA for capital-intensive or leveraged names (Telecom/ICT, Transportation & Tourism, Media); P/E where earnings are the cleaner read (Health Care, Food & Beverage, Commerce & Retail); and P/BV as a check on whether a “cheap” or “rich” P/E is actually a return-on-equity story.
From Public Comparables to a Private Company Valuation in Thailand
Every multiple in the comparables set is a public-market, minority-stake, freely-tradable reading. None of those three conditions typically hold for a private company transaction, so a public comparable is a starting reference point for business valuation — not a direct valuation output.
Three adjustments are generally required before applying a public multiple to a private Thai company:
First, normalize the earnings or EBITDA base for one-off items and accounting policy differences between the target and its public peers. Second, select the multiple that actually fits the target’s balance-sheet and cash-flow profile, rather than defaulting to whichever multiple is most commonly quoted for the sector. Third, apply discounts or premia for marketability, control, size, and company-specific risk — the standard private-company adjustments.
These discounts should be applied additively and with judgment, not mechanically. Compounding the high end of every discount will typically understate the value of a target with genuine structural advantages — a defensible market position, multi-year customer contracts, or a credible management succession plan. Conversely, applying only the low end of each discount will overstate the value of a business that is thinly capitalized, customer-concentrated, or owner-dependent.
One more nuance worth flagging: where the reference public comparable itself sits at a sector extreme — Electronics or Telecom on a P/BV basis, for instance — a second-tier or mid-cap peer within the same industry is usually the more appropriate benchmark than the sector’s single richest name. Scale, contract structure, and brand recognition rarely transfer proportionally to a smaller private target.
The Bottom Line for Q3
Thailand enters the second half of 2026 on genuinely better footing than it’s had in years — steadier politics, a stabilizing macro backdrop, and a public market that has already re-rated to reflect both. But “better footing” is not the same as “further re-rating ahead.” The public market gains are largely behind us, and the multiples now on the board should be treated as a normalized, industry-specific starting point for private valuation work — not a signal to reach for higher numbers because sentiment has improved.
