DELTA — Delta Electronics (Thailand) PCL
Thesis
Stance: WATCH → CONDITIONAL BUY (scaled entry). World-class business at a speculative price. Delta Electronics (Thailand) is the world's dominant AI server power supply manufacturer — the Thai-listed manufacturing arm of Delta Electronics (2308.TW, Taiwan) that physically builds the PSUs, liquid cooling CDUs, and rack power systems now powering NVIDIA GB200/GB300 deployments globally. The fundamental business is exceptional: ~28.5% ROIC, growing 20%+ annually, gross margin expanding from ~21% to 27.1% over five years, net cash balance sheet. The problem is the price. At ~146x trailing P/E and ~105x EV/EBITDA, the stock is priced for flawless execution of a 10-year AI buildout. The stock is up 279% in 52 weeks. Analyst consensus target (THB 250) sits 14% below spot. One independent DCF (dbl.fund) implies a -48% five-year expected return at current prices.
What has to be true (the single most important thing): Hyperscaler AI infrastructure capex sustains at or above the current run-rate through 2027-2028. If hyperscalers slow, trim, or pause capex, DET's growth derates AND the P/E compresses simultaneously — a toxic combination. The buy thesis is not undervaluation; it is durable AI-infrastructure growth bought at a very high price, where DET's ~60% group share in AI server PSUs and NVIDIA GB200/GB300 certification create a moat worth a premium multiple.
Bull case: Delta holds ~60% of the AI server PSU market (group-wide), is the primary supplier for NVIDIA GB200-era deployments, is ramping liquid cooling CDU capacity in 2025-2026, and benefits from Thailand's tariff advantage (36% US tariff vs. China 145%). Revenue grew 20% in FY2025; analysts estimate ~24% in FY2026. FCF positive, net cash balance sheet. Pure-play AI infrastructure exposure via a SET-listed name.
Bear case: ~146x P/E with FCF yield of 0.36% leaves zero margin for error. Average analyst target is below spot. Hyperscaler capex cycles are notoriously lumpy. The EV Mobility segment is under pressure from Western OEM delays. The parent (~76% ownership) limits minority shareholder governance rights. Customer names are undisclosed — concentration risk is real but unquantifiable.
Conviction: Low on a new position at the current price; medium as a long-term hold if already in at a lower cost basis. The business quality is High (A-grade); the entry is the problem (C-grade for value). Overall: B+ business, B- management. The path to a buy is a confirmed Q1 2026 earnings beat plus a pullback to THB 250-270.

Business
DET is a contract-and-own-design (OEM and ODM) electronics manufacturer. It designs and builds the power conversion equipment that keeps AI servers running: the box that takes dirty grid power, converts it to clean stable DC at the right voltage, and delivers it to NVIDIA GPUs at hyperscale data centers. It also makes EV powertrain components, industrial automation equipment, and data center cooling systems. ~95% of revenue is hardware product sales; zero is recurring software. It is the Southeast Asia, Oceania, and India regional operating hub of the Taiwan parent. ~75-80% of revenue is export-oriented (North America, Europe, Asia).
Business segments (FY2025 est.)
| Segment | Revenue share | What it does |
|---|---|---|
| Power Electronics | ~53% (confirmed ~51-53% in 2024-2025) | Server/AI PSUs, fans, thermal management, appliance/PC power, custom designs |
| Mobility | ~18% | EV powertrain: on-board chargers (OBC), DC-DC converters, traction inverters |
| Infrastructure | ~17% | Data center power/UPS, telecom power (-48V), EV charging, renewable energy, liquid cooling CDUs |
| Automation | ~12% | Industrial automation (sensors/drives/controllers), building management, LED smart lighting, surveillance |
Segment detail and per-unit economics
Power Electronics (~53%): AI server PSUs (2.5kW to 10kW+, Titanium efficiency, NVIDIA GB200/GB300-certified); standard server PSUs (400W-2kW); declining desktop/workstation commodity mix; DC cooling fans, EMI filters, solenoids. ASP: AI server PSUs $200-600+/unit; traditional server PSUs $80-200. Delta captures ~$1,000-2,000 in PSU content per GB200 NVL72 rack (BOM estimate). NVIDIA AVL qualification is a 12-24 month process creating a 3-5 year revenue lock-in per design win. Power Electronics grew +31% YoY in 2025; AI power is now ~25% of total group revenue (~THB 50B, up from negligible in 2022).
Mobility (~18%): OBC ($200-500), DC-DC converter ($100-200), traction inverter, combined control units ($500-800/vehicle). Customers implied to be Western European and American auto OEMs. EV parts represented ~1/3 of historical revenue. Currently under pressure: GM/Ford/European OEM EV program delays compressed the segment; EV inventory provisions were a key driver of the 4Q24 gross margin collapse. The segment is an AI-bull-masked structural drag with recovery optionality.
Infrastructure (~17%): Liquid cooling CDUs (1.5MW L2L for GB200 NVL72; 4RU in-rack 140kW for GB300; sidecar liquid-to-air), data center UPS, EV charging, -48V telecom power. CDUs use plate-type heat exchangers; the 1.5MW CDU is certified on NVIDIA's AVL/RVL. CDU revenue expected +140% YoY in 2026 — the fastest-growing sub-segment, potentially 5-10% of revenue by FY2027.
Automation (~12%): Steady, not a growth driver; more cyclical than AI power; provides diversification.
Customers and partners
Individual customer names are NOT disclosed — the primary disclosure gap vs. US-listed peers. Estimated cluster shares: major US hyperscalers (undisclosed) ~25-30% of revenue (AI power, concentrated among 3-5 names, MSFT/AMZN/GOOG/META inferred); Western auto OEMs ~15-18%; Asian server ODMs (Supermicro/SMCI, Compal, Hon Hai/Foxconn, Quanta, WIWYNN) ~10-15%; telecom/ICT ~8-10%; industrial automation ~8-10%. If the top AI hyperscaler customer cut orders 20%, DET revenue would decline ~5-6%. Top-5 customers likely exceed 50% of revenue (an undisclosed risk).
NVIDIA relationship: Delta PSUs on NVIDIA AVL for GB200 NVL72 (confirmed); Delta CDUs on AVL/RVL for GB200 NVL72 1.5MW and GB300 in-rack 140kW (confirmed). Showcased "Grid-to-Chip Power Solutions for Gigawatt-Scale AI Data Centers" at NVIDIA GTC 2025; 800VDC solutions at OCP Global Summit 2025 (1.1 MW-scale racks). Delta is one of ~5 companies listed as NVIDIA's partner for 800V HVDC. Revenue lock-in comes from design-in, not a signed supply contract.
Technology edge (first-principles)
For AI servers the challenge is converting AC to DC at scale, efficiently, without corrupting the power signal. A single NVIDIA H100 draws ~700W; a GB200 NVL72 rack packs 72 GPUs and draws ~120,000W (120kW); next-gen Kyber racks (2027+) exceed 1,000kW (1MW). Delta's breakthrough: efficiency at 50% load matters more than at 100%, and specialized topologies (totem-pole bridgeless PFC with GaN transistors at 99% efficiency; LLC/CLLC resonant converters using ZVS/ZCS at 96-98.5%) exceed 96% efficiency at all loads. Delta pioneered the world's first 80 Plus Titanium server PSU (with Dell, 2012). The 800V HVDC shift: at 120kW/rack, 48V distribution requires ~2,500A and thick copper busbars; NVIDIA's 800V architecture cuts current 16x, reducing copper ~45% and adding 5%+ system efficiency. Delta is building a 72kW AC-DC Server Power Shelf (98% efficiency) and 90kW DC-DC Server Power Shelf (98.5% efficiency) for it.
Moat and competitive position
Delta's economic engine is a certification-based oligopoly in Titanium-efficiency AI server PSUs. Sources of moat, prioritized: (1) NVIDIA AVL certification — first mover on GB200 PSU and CDU; 12-24 month requalification cycle for any switch; (2) power-density leadership from 10+ years of R&D (first Titanium PSU co-developed with Dell, 2012); (3) system-level integration — PSU + CDU + 800VDC busbar + UPS from a single qualified vendor, harder to replicate than individual products; (4) manufacturing scale in Thailand (Plants 1-7 main campus, Plant 8 + R&D opened Feb 2024 at 30,400 sqm, 2 Wellgrow plants, plus Slovakia/India/Myanmar) with the tariff advantage vs. China; (5) parent R&D support (~9% of revenue group-wide; group revenue NT$40B+ funding $1B+ R&D). Moat verdict: narrow but real, 5-7 year durability before Chinese competition and the 800VDC certification reset close the gap. Peers: Lite-On (2301.TW, ~15-20% AI PSU share), Acbel Polytech (6165.TW, ~10-15%), FSP Group (3015.TW, ~5-10%); Vertiv (VRT) and Schneider Electric (SU.PA) as full-system integrators; Chinese entrants (Megmeet, Huawei supply chain, BYD-adjacent) advancing but not yet on US hyperscaler AVLs.

*FY2026E: analyst consensus ~24% revenue growth (DBS / Kaohoon). Forward EPS cited THB 2.50 (deep-dive) to THB 2.63 (buy-checklist) — both retained. Note: the FundamentEdge gate table also cites a longer revenue history (FY2021 +34.2%, FY2022 +39.9%, FY2023 +23.5%, FY2024 +12.5%, FY2025 +20.3%); these are alternative-source growth rates and differ slightly from the headline +28/+23/+13/+20 series — both retained as sourced.
Gross margin expanded from ~21% (FY2021 area) to 27.1% (FY2025), driven by AI PSU mix shift. The trajectory is NOT linear (see Q4 2024 below). Operating margin recovered 250bps from 10.7% (FY2024, elevated opex ahead of capacity ramp) to 13.2% (FY2025) on Wellgrow operating leverage. FY2022-FY2025 revenue CAGR = 18.7%.

Balance sheet: Net cash ~THB 19B (~THB 18,820M per StockAnalysis); total debt/equity 2.1% (2.13%) — essentially unlevered. No ATM programs, shelf registrations, warrants, or convertibles. FCF self-funds operations and the current capex program; no equity raise needed. FCF yield is negligible at current market cap (0.36%); FCF would be ~THB 20-25B if capex normalized to maintenance levels. Capex/revenue: ~6.6% FY2022 → 7.9% FY2023 → 9.0% FY2024 → 7.5% FY2025.
ROIC vs. WACC: ROIC 28.5% vs. estimated WACC 8-10% (Thailand cost of equity; minimal debt so WACC ≈ cost of equity). Spread +18-20% — significant economic value creation. The market is capitalizing this at ~146x earnings.

Q4 2024 was the anomalous trough: gross margin cratered to 22.46% from 27.59% in Q3 2024 (cited variously as 22.2% / 22.4% / 22.46% and prior-quarter 27.5% / 27.59% across fragments — all retained). Drivers: EV inventory provisions, customer discounts, and warranty charges. It was NOT pre-warned by management. 2025 showed structural gross margin recovery (25-28.56%); Q4 2025 revenue +38% YoY (also cited +50% YoY in the buy-checklist Gate 2 — both retained), GP +44% incremental margin, net profit +252% — confirming AI mix is margin-accretive.
Incremental margin analysis (last 8 quarters)
| Q1'24 | Q2'24 | Q3'24 | Q4'24 | Q1'25 | Q2'25 | Q3'25 | Q4'25 | 4Q Avg | |

| GP YoY (THB M) | +437 | +2,659 | +2,826 | -1,264 | +2,955 | -113 | +3,158 | +7,109 | +3,277 |
| Incr. gross margin | 7.8% | 45.4% | 51.4% | -32.6% | 62.3% | -4.2% | 31.6% | 44.5% | 25.1% |
| Incr. EBIT margin | 5.6% | 31.4% | 31.6% | -71.1% | 38.7% | -26.6% | 14.0% | 36.5% | 7.6% |
Stripping the Q4 2024 outlier (incremental GM -32.6%, incremental EBIT -71.1%), the 7-quarter average incremental gross margin is +35%+. Q1 2025 was the recovery signal (62.3% incremental GM, highest in the dataset). Sustainable incremental EBIT ~25-35% when AI power drives growth and EV distortions are absent. The Q4 2024 event is the key lesson: margins can crater when non-AI segments face unexpected inventory or customer issues.
Other items: New Global Minimum Tax (OECD Pillar Two) introduced a THB 3.4B expense in FY2025 — a recurring annual drag; management mitigates via substance-based income exclusion provisions. Capex incremental-revenue efficiency ~2.0-3.0x over 2022-2025 (the 2024 ratio of 1.2x was low because capex ramped ahead of Wellgrow coming online; 2.2x in 2025 confirms productivity). Q4 2025 annualized revenue ~THB 231B vs. FY2026E consensus ~THB 245B implies only ~6% growth off the Q4 run-rate (potentially conservative).
Industry landscape
DET sits at the Server PSU / AI Power Shelf layer of the AI power-delivery value chain — between the facility PDU/UPS (Vertiv, Eaton, Schneider) and the VRM on the GPU board (MPS/MPWR, Renesas, Infineon), feeding NVIDIA/AMD accelerators and ultimately the hyperscalers. The AI server PSU market is an oligopoly at the premium end (Delta ~60% group share, Lite-On, Acbel share >80% combined) and fragmented at the commodity end. Barriers to entry are qualification cycles (18-24 months on NVIDIA's AVL), not capital. TAM: global data center PSU market ~$14B by 2026 (Yole Group) at ~20% CAGR; AI-specific server PSU ~$4-6B in 2025 at ~21.5% CAGR to 2031; liquid cooling CDU market ~$2-5B by 2027. Key upstream bottleneck: GaN power semiconductors (Infineon, Navitas, Transphorm, ROHM) with 18-24 month capacity-expansion cycles. We are in the early-to-mid phase of the AI buildout cycle (2025-2027 high intensity); peak risk is real after 2027.

KEY FACT — founder's son CEO
Victor Cheng is the son of Bruce C.H. Cheng, Delta Electronics' founder and Honorary Chairman (founded Delta 1971, Chairman until 2012). This is NOT widely disclosed in standard bios but is confirmed in Delta's 360 internal magazine interview. Victor is a different son than Ping Cheng (who became Taiwan parent CEO in 2012). Career: 1993-1999 display business (Chungli); 2002-2014 President then Chairman of Delta Networks Inc. (DNI), growing DNI revenue from ~$200M to ~$800M; 2014-2017 GM Power System Business Group; 2017-2019 GM ICT Business Group; 2019-2023 EVP Infrastructure Business Group at the Taiwan parent; Jan 2024 DET CEO. His appointment timing (just as AI server demand accelerated) and his PSBG/IFB background were not coincidental. No regulatory actions, lawsuits, or enforcement history for any named executive or director.

Total Delta group (parent + affiliates): ~76% combined. Ownership data as of Feb 27, 2026. Individual executive/director holdings are NOT disclosed at US DEF 14A granularity; no individual executive holds a material personal position (>0.1%) beyond the parent structure. Skin-in-the-game alignment is structural, not personal. No open-market insider buying with personal funds.
Capital allocation
Capital allocation grade B to B+. ROIC 28.5% (capital creating value); consistent 30% dividend payout (no cuts observed); no value-destructive M&A at the DET level; capex productive and measured. No buyback program (structurally explained — the parent owns 76%, so buybacks would primarily benefit minorities). M&A is primarily intra-group: Eltek Australia acquisition (2021, from parent group), Eltek Thailand acquisition (~THB 501M, Nov 2025 disclosure, ~0.56% of net tangible assets, "small size" below shareholder-vote threshold, Audit Committee approved, independent fairness opinion not confirmed), Delta Switzerland 49% stake sale to Delta International Holding B.V. (USD 12.68M), machinery acquisitions from related parties (accumulated ~USD 13.6M), and an intercompany loan disclosed April 3, 2025 (terms in binary PDF). SBC is negligible (no employee stock option / equity grant program identified — no spring-loading risk, but also no equity-based long-term alignment). Group capex guide NT$40B (~$1.3B USD) for 2026 across four countries.
Governance flags
Parent control (~76%) gives effective veto over all shareholder votes; board elections are a formality; minority shareholders (~24% free float) have limited recourse. Board: 5 of 11 directors are Delta Group representatives; 2 Thai non-executives; 3 formally independent (Tipawan Chayutimanta CPA No. 6870, Somchai Harnhirun, Saowanee Kamolbutr). Specific flags: (1) Anusorn Muttaraid — 30 years on the board (since 1994) as a "non-executive" director, independence questionable in practice; chairs Nom.&Comp. and Privilege committees; (2) Dr. Somchai Harnhirun — active Thai Senator (2019-present), ex-Deputy Minister of Industry (2017-2019), on the board as an independent director — a dual political/corporate conflict; (3) Chu Chih-yuan (Roger), a Delta Group representative, historically sat on the Audit Committee alongside the three independents — a structural independence weakness; note he may have departed (not in the most recent board table — if so, a governance improvement). January 2025 exchangeable bond: the parent (via Delta International Holding B.V.) issued a $525M zero-coupon bond exchangeable into DET shares to HSBC, pledging 62M DET shares (0.5% of outstanding) as collateral while retaining economic exposure. Linklaters advised on "one of the largest Thai equity-linked transactions in recent years." This is the parent monetizing/extracting liquidity at high prices, not a sale and not insider buying — a yellow-flag conviction signal.
Credibility / follow-through (credibility score 7/10)
DET gives directional outlook ("double-digit growth") not US-style numeric guidance. Follow-through ~70-80% on directional statements. The Q4 2024 gross margin crash (22.2% vs. 27.5% Q3) was the clearest miss without advance warning — the key blemish. Weasel-language detection: "double-digit" (10% and 29% both qualify), "assuming stable external conditions," "visibility" (not committed backlog) — deliberate ambiguity, typical of Thai SET names, limits forward modeling precision. Overall management grade: B- / Yellow (deep-dive cites B / Yellow). Competent operators in a parent-controlled structure; no fraud, no litigation, no enforcement; structural governance gaps and minority-shareholder risk are the key concerns. The central alignment risk: Victor Cheng's true wealth is tied to the Taiwan parent (2308.TW) via the founder-family position, not DET shares — his incentives may favor the parent over DET minority shareholders if value is transferred via non-arm's-length related-party pricing.

Near-term (0-12 months): Q1 2026 earnings (the buy-checklist flags April 28, 2026 as the date / 2 days from checklist; the deep-dive and profile say results expected May-June 2026 — both retained) — tests whether the +38% YoY Q4 2025 growth and 27-28% gross margin sustain; Wellgrow plant full ramp feeding H1 2026 revenue; first meaningful 800VDC power-shelf volume orders (H2 2026); any named-hyperscaler disclosure would be a significant re-rating event. Medium-term (1-3 years): BP6 completion (April 2027; 4-storey, 51,365 sqm, Bangpoo; AI power + liquid cooling; started Dec 2025) enabling CDU to scale to 5-10%+ of revenue; NVIDIA Kyber rack (1MW+) ramp in 2027 with Delta developing the power infrastructure; EV/Mobility segment recovery optionality (~18% of revenue, depressed); liquid cooling becoming a disclosed segment (+140% YoY expected 2026). Secular tailwinds: GPU power-density escalation (each generation roughly doubles TDP → doubles PSU revenue per rack: H100 700W → B100/GB100 1,000-1,200W → next-gen 2,000W+); hyperscaler capex ($200B+ combined 2025-2026 — MSFT ~$80B FY2026, AMZN $100B+, GOOG $70B+, META $65B+); 800VDC transition (new product cycle, Delta co-developer, 2027+ ramp); liquid cooling adoption (physics mandate above 120kW/rack); Thailand tariff advantage (36% vs. China 145%).
Risks (bear)
Risk 1 — Hyperscaler AI capex plateau (HIGH probability, HIGH impact): if hyperscalers trim or pause 2026-2027 commitments (DeepSeek efficiency gains, macro budget cuts, regulation), DET's order book thins and the P/E re-rates violently. A 60x P/E on FY2026 EPS gives ~THB 158 (46% downside). Risk 2 — Extreme valuation / re-rating (HIGH): at ~146-147x P/E, ~105x EV/EBITDA, 0.36% FCF yield, any earnings miss triggers severe de-rating; no operational mitigant exists. Risk 3 — Q4 2024 recurrence / margin volatility (MEDIUM): EV inventory, customer discounts, warranty provisions created a -32.6% incremental gross margin quarter; the multi-segment model carries this structural volatility. Risk 4 — Chinese PSU competition (MEDIUM, 2-4yr horizon): Megmeet, Huawei supply chain, BYD-adjacent suppliers advancing; could win Chinese-hyperscaler (Alibaba, Tencent, ByteDance) AVLs first, then Western; each new product generation restarts the certification gap. Risk 5 — EV Mobility pressure (HIGH probability, LOW-MEDIUM near-term impact): Western OEM EV delays drag growth and margins. Risk 6 — GaN semiconductor supply constraint (LOW-MEDIUM): wide-bandgap GaN is tight with 18-24 month expansion lag; Infineon dominant. Risk 7 — parent-subsidiary governance (LOW-MEDIUM): related-party transactions could transfer value to the parent at non-arm's-length terms; structural, not closable without ownership change. Risk 8 — THB/USD currency: USD-revenue / THB-cost natural hedge favors DET when USD is strong but can reverse. Longer-horizon disruptors: integrated VRM / on-die voltage regulators (Empower Semiconductor, MPS) could shrink the discrete PSU market (5-10yr); Vertiv/Schneider as full-system integrators with bundled software; architecture obsolescence (low probability, 7+yr).
Behavioral traps active at purchase: FOMO (+279% in 52 weeks, $100B milestone, CNBC/Bloomberg coverage) and narrative seduction ("dominant AI infrastructure player," "#1 server PSU maker," "only Thai $100B company"). Note 8/17 analysts rate Sell or below consensus. Correlation: highly correlated with NVDA/AMD/ASML AI-infrastructure names — adding DET increases AI-cycle concentration.
Valuation / DCF
Margin of safety: near zero. No margin of safety exists at ~147x P/E with 0.36% FCF yield. You are buying growth, not value.
Current multiples (THB 290-293, Apr 2026)
| Metric | DELTA.BK | Context |
|---|---|---|
| P/E TTM | ~146-147x | FY2025 EPS THB 1.99 |
| P/E forward (FY2026E) | ~111x | EPS consensus THB 2.63 |

Peer comparison
| Company | Ticker | P/E TTM | EV/EBITDA | FCF yield | Rev growth |
|---|---|---|---|---|---|
| Delta Electronics Thailand | DELTA.BK | 146x | 105x | 0.36% | +20% |
| Delta Electronics (Taiwan) | 2308.TW | 90x (~55x fwd) | 55x | ~1% | +32% |
| Lite-On Technology | 2301.TW | ~25x | ~12x | ~3-4% | +15% |
| Acbel Polytech | 6165.TW | ~30x | ~15x | ~2-3% | +25% |
| Vertiv Holdings | VRT | ~45x (~55x fwd) | ~30x | ~1.5% | +14% |
DET trades at a 3-5x multiple premium to its direct PSU peers (Lite-On, Acbel) and ~2x premium to its own Taiwan parent. The premium reflects Thai-market scarcity (only listed SE Asia AI-PSU play), SET/NVDR retail accessibility, and the $100B momentum re-rating.
DCF / scenario framework
- Bull: 5%+ DCF assuming 20% CAGR x 7 yrs → THB 200-300+ (where the stock is now)
- Base: 10% CAGR x 5 yrs + normalize → THB 80-120 (a rough DCF — 20% growth 5yr, then 10% 5yr, 5% terminal, 12% net margin, FCF ~65% of net income, 10% discount — implies ~THB 80-120)
- Bear: P/E de-rate to 30-40x → THB 60-80; at 25x forward → THB 63-80; from THB 290 that is 70-80% downside
- Independent dbl.fund DCF (conservative/base): THB 39-58; implies ~-48% five-year expected return at current prices
- Consensus average analyst PT: THB 250 (14% below spot of 290); high THB 350, low THB 162; 8 Buy / 4 Hold / 5 Sell (17 analysts); DBS HOLD with THB 185 target (old note) — and separately a much earlier DBS BUY at a THB 100 target (pre-rally, since exceeded); both old DBS targets retained as sourced and flagged stale
Implied expectations
To justify ~146x P/E the market is pricing ~20%+ revenue CAGR for 7+ years, stable-to-expanding net margins (12-15%), and continued ROIC above 25%. Using a terminal-multiple framework: if FY2026E EPS is THB 2.63 (+32%) and FY2027E THB 3.29 (+25%), a 30x P/E in 3 years gives THB 99 (40x: THB 132; 50x: THB 165). To justify THB 293 at a 40x terminal multiple in 3 years, EPS would need ~THB 7.30 — roughly 3.7x FY2025 EPS over 3 years = ~54% CAGR. This is aggressive. The current price is defensible ONLY if the AI capex cycle sustains above current levels through 2028, AND DET sustains/expands gross margins, AND the market maintains a premium multiple.
Bull-case price target (buy-checklist exit)
THB 400-450 (~30x EV/EBITDA on forward FY2027E estimates) = 35-55% upside from current. Downside bear scenarios: 20% hyperscaler capex cut → 10% FY2026 growth, GM back to 24%, EPS THB 2.10, 50x P/E → THB 105 (64% downside); moderate bear 15% growth, EPS THB 2.40, 80x P/E → THB 192 (34% downside). Business quality grade: B+ overall; A for business quality, C for value at current price. Financial health grade: A-.
Decision log
2026-04-26 — Initial research sweep. /profile, /deep-dive, and /mgmt-dd written; founder's son CEO (Victor Cheng = son of Bruce C.H. Cheng) flagged as the key non-public governance fact. Deep-dive verdict: world-class business at a speculative price; conviction LOW on new position at THB 290, MEDIUM as a hold at lower cost. Management grade B- / Yellow.
2026-04-26 — /checklist (PRE-BUY), price THB 292-293. FundamentEdge gates 5/5 PASS (with maximum respect for valuation risk). Pre-buy scorecard: thesis clear YES; business understood YES; incentives aligned PARTIAL; financials healthy YES; valuation reasonable NO; behavioral trap (FOMO + narrative seduction) YES; technicals support buying now NO (60% above 200-day MA, near 52-week high, Q1 earnings risk). Verdict: WATCH → CONDITIONAL BUY (scaled entry). Path to a buy: (1) Q1 2026 earnings confirmation — open a 30% starter if revenue growth sustains >20% YoY and gross margin holds >25%; (2) target entry THB 250-270 on a 10-15% pullback; (3) scale in over two tranches. Target size 3-5% of portfolio max. Exit/stop framework: bull PT THB 400-450; stop-think at two consecutive quarters of revenue deceleration or gross margin below 24%; hard exit below ~THB 175-185 (40% max loss) or if hyperscaler AI capex is meaningfully cut, a major NVIDIA-certified PSU qualification is lost, or a Chinese PSU competitor wins material share. Do NOT buy a Q1 miss reflexively — distinguish EV-related (acceptable) from AI-PSU-demand-related (thesis risk).
Technical note (Apr 23-26, 2026): ~93% of 52-week range; ~60% above the 200-day MA (~THB 182); ~20% above the 50-day MA (~THB 240-250); nearest support THB 250-260, secondary THB 200-210, resistance THB 319. Technical recommendation: WAIT for a pullback to THB 250-260 or a confirmed earnings catalyst.
