BlackRock Smaller Companies Trust jumps 4% on merger plan with Throgmorton

BlackRock Smaller Companies Trust has proposed a merger with BlackRock Throgmorton Trust to form a growth-focused vehicle with approximately £780m of net assets, triggering a 4% rise in Smaller Companies Trust shares to 1,433p. Throgmorton would be wound up with shareholders offered either a roll into the enlarged trust or a cash exit at a 1% discount to NAV (capped at 38% of Throgmorton’s share capital); Smaller Companies Trust will run a parallel tender for up to 28% of its shares. The combined trust would be co-managed, benefit from >75% portfolio overlap, cut management fees to 0.5% on the first £500m (0.45% above £750m) yielding an estimated ongoing charges ratio of 0.63% (vs 0.8% currently), and BlackRock will waive six months’ fees to cover ~£1.9m of transaction costs; activist Saba (10.4% of Smaller Companies, 17.8% of Throgmorton) has committed to support and tender. Shareholders vote on 30 March 2026 and a five-for-one share split is planned to improve accessibility.

Analysis

Market structure: The merger creates a £780m growth-focused UK smaller‑companies trust with lower fees (0.5% decaying to 0.45%) and an estimated OCF ~0.63% vs peers ~0.80%, making it a likely net winner for inflows from retail and fee‑sensitive institutional buyers; Saba’s tender commitments (10.4% and 17.8%) and the 5-for-1 split increase immediate sell liquidity but also retail accessibility. Competitive dynamics: Larger scale gives the combined vehicle pricing power versus higher‑cost active small‑cap trusts (who face margin and flow pressure); overlap >75% by value reduces immediate rebalancing need but raises short‑term liquidity impact if forced sales occur. Cross‑asset: direct FX and commodity impacts immaterial; fixed income/credit irrelevant except for potential balance‑sheet flows into UK Gilts if large cash exits occur; expect transient option vol compression on both trusts and on BLK (parent) equity. Risk profile & catalysts: Near term (days–weeks) risks are vote outcome (GM 30 Mar), tender execution and up to 38% cash exit cap — a failed vote or >30% cash exits could widen discounts by 5–15%. Longer term (6–24 months) risks include PM co‑management friction, underperformance vs peers, and fee waiver expiry after 6 months; catalysts to accelerate flows: post‑merger marketing, index inclusion thresholds and Q2 fund flows reporting.

Key Decisions for Investors

• Establish a 2–3% long position in BlackRock Smaller Companies Trust (UK‑listed) ahead of the 30 Mar GM; set a tactical target +12% and stop −6% with review at the tender window outcome (expectNAV accretion from fee cuts and Saba support).
• If capital‑efficient, buy a 4–6 month call spread on BLK (NYSE:BLK) sized 0.5–1% of portfolio risk: buy a ~5% OTM call, sell a ~10% OTM call to play positive sentiment and scale benefits without large delta exposure; close on material underperformance or post‑earnings volatility >25% IV move.
• Initiate small (1–2% portfolio) short positions in UK small‑cap active trusts trading OCF >0.80% and persistent NAV underperformance versus peers (identify borrowable ETFs/trusts); target 10–20% downside over 6–12 months as flows re‑rate to lower‑cost vehicle.
• Trigger/monitor rules: if GM fails on 30 Mar, exit long positions immediately; if cash tenders exceed 25–30% of issued capital in either trust, reduce longs by 50% to avoid NAV dilution/discount widening; reassess after 6 months when BlackRock’s 6‑month fee waiver expires.
