ROCKWOOD STRATEGIC PLC (RKW) — Investment Research Note

Executive summary

Rockwood Strategic is a UK-listed investment trust (Main Market, LSE) managed by Rockwood Asset Management (formerly Harwood Capital), running a concentrated, engaged, "value + recovery" strategy in sub-£250m UK small-caps. Over the five years to March 2026 NAV total return is +97.4% versus the FTSE AIM All-Share at −40.1% — the best performing UK equity investment trust over that period per the AIC. The single most important point for valuation today: RKW is an investment trust whose value is anchored by its published NAV (~312p as at 12 June 2026); the shares trade at a small discount to NAV and the AI thesis is at best indirect, via a handful of portfolio holdings (Filtronic, Kooth, Tribal).

Fair value estimate

• Methodology: NAV-based valuation (only appropriate approach for a closed-end investment trust). Cross-checked against the manager's post-period-end NAV updates and portfolio marks.
• Anchor: NAV per share was 266.44p at 31 March 2026 and 311.64p at 12 June 2026 (announced 17 June 2026 2026-06-17 full year). Post-period the fund also disclosed takeover offers for Treatt (+48%) and Van Elle (+58.5%) and a further +69% move in Filtronic — all NAV-accretive but partly already reflected in the June mark.
• Fair value range: 290p – 340p per share, implying a market cap range of £176m – £207m. The low end assumes the mark reverses somewhat as recent post-period gains settle; the high end allows a modest (~5%) premium to spot NAV to reflect the manager's demonstrated ability to compound at >15% IRR, which historically has justified periods of premium-to-NAV pricing (the shares averaged a 2.9% premium in FY25 and issued new stock at a premium through both FY25 and FY26).
• Midpoint: c.315p / £191m market cap.
• Current price 316p / market cap £191.6m → absolute upside of roughly 0% (range −8% to +8%). The stock is trading essentially at fair value; it is neither cheap nor expensive on the NAV alone.

Sector context

• Sector: Financials / Financial Services (ICB) — but functionally this is a closed-end UK small-cap investment trust, not an operating financial. Sector benchmarks are AIC UK Smaller Companies peers.
• Quality vs. peers: Above typical peers on performance (No.1 in AIC UK Small Companies over 3 and 5 years), balance sheet (net cash, no gearing) and disclosure. Fees are competitive (1.0% mgmt + 10% performance over 6% hurdle, subject to caps).
• Listed peers: Odyssean Investment Trust (OIT), Aberforth Smaller Companies (ASL), River UK Micro Cap. Rockwood is smaller and more concentrated (24 holdings, top 10 = ~59% NAV) than most peers.

Investment thesis

• Best-in-class manager track record with a differentiated engaged/activist approach: 200% NAV growth in three years, No.1 UK small companies IT over 3 and 5 years, with a strategy that reliably converts value opportunities into realised returns via engagement, board changes, and takeovers (Galliford Try +48% IRR, Treatt +48% bid premium, Van Elle +58.5% premium, Filtronic +69% post-period) 2026-06-17 full year.
• Portfolio contains identifiable AI-adjacent optionality without the AI premium: Filtronic (RF components into SpaceX/Starlink ground stations & LEO satellites) has been transformational, and Tribal Group (Higher Education SaaS) and Kooth (mental-health platform with proprietary US-state contracts) provide additional though modest AI-adjacent exposure 2025-11-18 half-year. You get this exposure at NAV, not at a growth-stock multiple.
• Growing scale, premium-to-NAV issuance, and index inclusion (FTSE All-Share, FTSE Small Cap) — self-reinforcing: broader universe, lower cost ratios, more liquid shares, and post-year end further net issuance took NAV to £180m by 12 June 2026 2026-06-17 full year.

Key risks

• Concentration risk: top 10 = 59% of NAV, and idiosyncratic blow-ups have hurt (Argentex written off in H1 26; Hostmore ~99% loss in FY25) 2025-11-18 half-year, 2025-06-18 full year. In a concentrated fund a single event can materially dent NAV.
• UK small-cap and AIM structural headwinds: sustained retail outflows, AIM tax-break cuts, weak IPO market, "soggy" domestic economy; the manager repeatedly flags this backdrop and depends on takeover activity to crystallise value 2025-11-18 half-year, 2025-06-18 full year.
• Valuation risk vs NAV and macro shocks: In March 2026 NAV was noticeably dented by "US military action against Iran" — a stark reminder that the concentrated equity book can move sharply on macro/geopolitical events, and the small premium/discount to NAV can widen quickly 2026-06-17 full year.

Operating leverage

For an investment trust, "operating leverage" is muted and largely fee-driven. Fixed overheads (director fees, admin, custody) total c.£0.5m–£1m annually; the ongoing charges ratio was 1.66% annualised at H1 26 and would fall further as NAV scales, because the management fee is now capped such that total fees do not exceed 3% of NAV, and fixed overhead does not scale with NAV 2025-11-18 half-year. Practical upside: on NAV growing from ~£180m to, say, £250m, the ongoing charge ratio would compress by perhaps 15-25bps — worth having but not a value driver. The real "operating leverage" here is portfolio-level: several holdings (Trifast, RM, Capita, James Fisher, M&C Saatchi, Filtronic) are themselves margin-recovery stories where the manager quantifies 3-10 percentage points of operating margin uplift potential 2025-06-18 full year — but that leverage accrues to the underlying companies, not to RKW's own P&L.

Value-trap signals

None identified. The fund has a growing NAV, a small premium/discount rather than a persistent deep discount, strong external validation (multiple awards, index inclusion), net cash on the balance sheet, and a manager with material personal ownership.

Earnings vs. expectations

An investment trust does not "guide" or have a consensus in the same way as an operating company. What is measurable is NAV vs. the manager's own 15% IRR target and vs. relevant indices:

• FY24: NAV TR +5.1% (below target, but ahead of FTSE AIM −8.6%) 2024-06-19 full year.
• FY25: NAV TR +21.0% (well ahead of target) 2025-06-18 full year.
• H1 FY26: NAV TR +12.5% in 6 months (well ahead) 2025-11-18 half-year.
• FY26: NAV TR +7.1% for the year (impacted by March Iran shock) but +17% in the ~2.5 months post period-end 2026-06-17 full year. Overall pattern: consistent outperformance of relevant indices and, on a rolling 3-5 year basis, comfortably ahead of the 15% IRR target.

Conviction

4 — high. Anchoring factors: (1) valuation is anchored by an audited, listed-equity NAV published monthly, so the fair value range is unusually tight; (2) the manager's track record is well-documented and independently verified (AIC rankings); (3) the trust's own market cap sits very close to NAV so the arithmetic is simple. Limiting factors: (i) NAV is portfolio-mark dependent, and a concentrated book can move sharply in weeks; (ii) any premium/discount to NAV can shift with sentiment toward UK small-caps, adding a second layer of price variability that is genuinely hard to forecast.
