BOKU, INC. (BOKU) — Investment Research Note

Executive summary

Boku operates the leading global network of Local Payment Methods (Direct Carrier Billing, digital wallets, and Account-to-Account real-time schemes), providing tier-one digital merchants (Netflix, Spotify, Meta, Sony, Amazon, Microsoft, Google) with a single integration to ~7bn consumer payment accounts across 60+ countries. After several years of accelerating growth culminating in FY2025 revenue of $128.8m (+30%) and adjusted EBITDA of $41.3m (32% margin), the company issued a material profit warning in July 2026 2026-07-08 trading update: H1 2026 underlying revenue growth slowed to just 11%, and FY26 guidance was cut to $135-142m revenue / $38-42m EBITDA vs consensus of $155m / $49.9m. The single most important valuation issue today is whether the H1 2026 miss reflects one-off merchant dual-sourcing and connection delays (as management asserts) or a structural slowdown as the mix shift to lower-take-rate A2A/wallets and pricing normalisation catch up with the growth story.

Fair value estimate

Range: 100p – 145p per share (implied market cap £286m – £414m); midpoint ~£350m / 122p.

Methodology: EV/adjusted-EBITDA multiple on FY26 guidance, cross-checked against cash-adjusted forward P/E.

• FY26 adjusted EBITDA guidance $38-42m; use $40m mid-case.
• Apply 8x-12x EV/EBITDA (fair for a niche payments platform growing high-single-digits with ~30% margins, well below higher-growth payments peers; low end reflects the credibility hit from July's warning).
• EV range: $320m – $480m.
• Add net cash of $103m at end-2025 (own cash, per 2025 accounts), less ~$23.5m of H1 2026 buybacks = ~$80m residual own cash today, though total group cash is much higher due to merchant funds. Convert at $/£ ~1.34 → ~£60m net cash contribution.
• Equity value: £298m – £418m → 100p – 140p per share.
• Cross-check: on the low end of FY26 net income run-rate (~$18-22m adjusted; ~£14-17m), current market cap of £320m implies ~19-23x — a reasonable but not cheap multiple, consistent with a fair-value conclusion.

Vs current market cap of £319.9m, this implies -10% to +30% upside — modestly undervalued but not compellingly cheap. Absolute upside to midpoint: ~9%.

Sector context

The ICB classification of "Industrials / Industrial Goods & Services" is technically correct but misleading — Boku is a fintech/payments infrastructure platform. Compared to true payments peers (Adyen, Nuvei, Worldline, dLocal), Boku sits below typical scale but with a clean balance sheet, narrower niche (LPMs for digital merchants), and more concentrated customer base (2 merchants = ~51% of 2025 revenue). Closest listed peers: dLocal (DLO) — LPMs in emerging markets, higher growth but customer-concentration risks; Nuvei (recently taken private); Adyen — much larger, broader scale. Quality/growth is in line with mid-cap fintechs; leverage is well below (net cash vs typically leveraged peers).

Investment thesis

1. Structural tailwind from cash-to-digital-payment transition in emerging markets. Global e-commerce is expected to reach ~$11tn by 2028 with LPMs accounting for ~60% of transaction value 2026-03 FY2025 results. Boku sits at the intersection of merchant demand for one-integration global access and central-bank-driven A2A adoption (PIX, UPI). Recent milestones: first PIX and UPI transactions in H1 2026 2026-07-08 trading update.
2. Fortress balance sheet allows patience through the current soft patch. Own cash of $102.9m at end-2025 with zero debt; H1 2026 buyback of 9.6m shares at $23.5m plus further extension announced 2026-07-08 trading update. Balance sheet gives management runway to invest through the disruption rather than cut costs into it.
3. New indirect route to market via Stripe partnership. In H1 2026 Boku signed its first channel partnership with a major global PSP (Stripe), with two merchants already live 2026-07-08 trading update. If replicated with other PSPs, this can materially expand addressable merchants without proportional sales cost — a genuine operating-leverage lever.

Key risks

1. Customer concentration is severe and worsening. 2 merchants accounted for $66.4m of $128.8m FY25 revenue (~51%) 2026-03 FY2025 results; H1 2026's miss was itself driven partly by "a key merchant's move to dual sourcing" reducing Boku's share in one market. Any single-merchant defection would be catastrophic.
2. Take rate structurally declines. Management flagged at the October 2025 Capital Markets Event that "blended take rates expected to trend down over time" as bundling and A2A scale 2026-03 FY2025 results. Revenue growth therefore must be driven entirely by volume — and July's miss shows how vulnerable this is when merchant onboarding slips.
3. Guidance credibility is dented. FY26 revenue guidance was cut ~10% and EBITDA ~20% just months into the year; the September 2025 interim narrative gave no hint of the extent of H1 2026 slowdown 2025-09-30 interim results vs 2026-07-08 update. Not disclosed but inferred: the market will apply a discount until management re-establishes a track record of meeting numbers.

Operating leverage

Boku is a classically high-operating-leverage business with an unusually high fixed-cost base. Gross margins are ~97-98% (adjusted operating expenses of $87.5m on $128.8m revenue equal roughly the entire cost base excluding cost of providing services which is only ~$1-3m). Staff costs alone were $66.1m in FY25 across 592 employees — largely fixed. The business demonstrated this leverage on the way up: FY24→FY25 revenue grew 30% while operating profit grew 205% ($6.2m → $18.9m) 2026-03 FY2025 results. However, H1 2026 shows the leverage works both ways: with revenue only up 11% (vs planned ~20%+), EBITDA margin compressed to 29% from 30.6% — highlighting that the fixed-cost investments made in 2025 do not flex down when volumes disappoint. At-scale incremental contribution margin is plausibly 50-60%+, meaning a 10-20% revenue beat vs current guidance could add $10-20m to EBITDA (26-53% uplift). This is the "long-tail upside" the investor prizes — but symmetrical downside risk is manifestly present.

Value-trap signals

• Customer concentration (top-2 = 51% of revenue) — this is a structural, not temporary, feature.
• Take-rate decay publicly acknowledged by management.
• Repeated methodology changes to adjusted EBITDA (H1 2025: currency conversion costs newly included in EBITDA — reduces reported margin, though justified) create a mild concern about earnings-quality/comparability.
• Guidance miss shortly after upbeat H1 (Jan 2026 trading update reported "strong momentum" for FY25; July 2026 update cut FY26 numbers materially).

Earnings vs expectations

Pattern: consistent beats FY23-FY25 (creating a positive momentum narrative), then a sharp break in H1 2026 with FY26 guidance cut by ~10% (revenue) and ~20% (EBITDA) vs consensus.

Conviction: 3 / 5 — moderate

Anchors: (1) unusually clean balance sheet with $100m+ own cash gives a hard floor; (2) audited accounts, PwC auditor, transparent APM reconciliations; (3) FY26 management guidance is fresh and concrete. Limits: (1) the H1 2026 miss creates genuine uncertainty about whether 20%+ medium-term revenue guidance is still credible; (2) customer concentration means a single merchant announcement could re-rate the shares 20%+ in either direction.
