Henry Root Letters – MOBILE WORLD – SEP 2026

Mobile World should pre-empt a structural holding-company discount by making the parent’s capital-allocation role explicit, transparent and shareholder-oriented.

• Dien May Xanh listed on 6 August, and its market capitalization exceeded Mobile World’s on seven trading days between 7 and 18 August; since then, Mobile World has generally traded at only a 10–11% premium to DMX.
• Mobile World owns about 86% of DMX, whose stake represents roughly 77–78% of Mobile World’s total market capitalization, leaving only 22–23% attributed to Bách Hóa Xanh, An Khang Pharmacy, other investments and parent-level net assets.
• Arisaig recommends five actions: define the economic purpose of the parent, publish a clear capital-allocation hierarchy, communicate look-through NAV regularly, return excess capital through dividends or buybacks, and protect minority shareholders through simple, arm’s-length structures.
• Its internal comparison of First Pacific, Masan Group, Jardine Matheson and SK Square estimates FY25 discounts to NAV of 17.2%, 60.5%, 26.3% and 38.3%, respectively; from FY21 to FY25, the discount narrowed by 43.6 percentage points for First Pacific but widened by 60.5 points for Masan Group.
• First Pacific has traded at a substantial discount since the early 2000s, while Masan Group moved from a 16.5% premium to NAV in FY21 to an approximately 60% discount by FY24–25 after Masan Consumer began trading on the HOSE main board on 25 December 2025.

Takeaway: Mobile World’s future valuation will depend not only on DMX and Bách Hóa Xanh’s operating performance but also on whether the parent can demonstrate superior capital allocation, return excess cash and maintain strong governance before any discount becomes entrenched.
