Sovereign Telecom: Leveraged Recapitalisation and WACC
Sovereign Telecom plc has £200m of debt carrying a 5% pre-tax interest rate and an equity market value of £800m. Its cost of equity is 11%, and the tax rate is 25%. EBIT is £120m. The board is considering a leveraged recapitalisation: issuing a further £300m of debt at 7% and using the proceeds to buy back shares. Advisers estimate that the higher gearing would raise the cost of equity to 14% and reduce the equity market value to £500m, while the debt would be rated below investment grade. Interest cover would fall to about 3.4x. The company has no major investment programme, and its shares have traded below book value for two years. The CFO argues that debt is cheaper than equity, so more debt must lower the WACC. A shareholder activist is pressing for a buyback to return excess capital.
1. Calculate the WACC before and after the proposed recapitalisation, and explain why the CFO's statement is incomplete.

Current WACC
Debt weight = £200m/£1,000m = 20%; equity weight = 80%. After-tax cost of debt = 5% × 75% = 3.75%. WACC = 0.20 × 3.75% + 0.80 × 11% = 0.75% + 8.8% = 9.55%.
Proposed WACC
Debt £500m, equity £500m, total £1,000m. After-tax cost of debt = 7% × 75% = 5.25%. WACC = 0.50 × 5.25% + 0.50 × 14% = 2.625% + 7.0% = 9.625%. The WACC rises slightly, not falls.
Why the CFO is incomplete
The CFO compares the cost of debt with the cost of equity without adjusting for the extra financial risk borne by equity. As gearing rises, the cost of equity rises to compensate for the greater risk of residual cash flows, and the interest tax shield is offset by expected financial distress costs. At the proposed gearing, the tax shield on the extra £300m is £300m × 7% × 25% = £5.25m a year, but the higher cost of equity and the below-investment-grade rating consume that benefit. The calculation also ignores the possibility that the £500m equity value already reflects distress, so the true WACC could be higher.
2. Discuss the factors that determine the optimal capital structure for Sovereign, including tax shields, financial distress and signalling.

Tax shield
Debt interest is tax-deductible, so moderate gearing adds value. The current interest of £10m produces a tax shield of £2.5m a year. The proposed interest of £35m produces a shield of £8.75m, but that is not a free lunch.
Financial distress
At high gearing, expected costs of bankruptcy, lost customers, supplier tightening and management distraction rise. Proposed interest cover is £120m/£35m = 3.4x, against 12x currently. A 30% EBIT fall to £84m would cut cover to 2.4x and could breach covenants.
Agency and flexibility
Too little debt allows managers to waste free cash flow; too much creates underinvestment and risk-shifting. A telecom needs spectrum and network capex, so preserving investment-grade access matters. The rating downgrade would raise future borrowing costs and may restrict access to debt markets.
Signalling
A buyback can signal confidence that shares are undervalued, but a debt-funded buyback when shares trade below book may also signal a lack of profitable investment opportunities. The board must decide which signal it wants to send.
Conclusion
The optimal structure balances the tax shield against distress and flexibility costs. Sovereign is probably near its optimum already; forcing gearing higher to hit a theoretical target is not justified.
3. Recommend whether the board should proceed with the full £300m buyback, a smaller buyback, or a special dividend.

Recommendation
A smaller buyback of £100m–£150m, possibly combined with a special dividend, is preferable to the full £300m buyback.
Illustrative £150m buyback
Debt becomes £350m and equity, if value is conserved, £650m. Gearing is 35%. Interest = £200m × 5% + £150m × 7% = £10m + £10.5m = £20.5m; interest cover = £120m/£20.5m = 5.9x. At a cost of equity of, say, 12.5%, WACC = 0.35 × 5.25% + 0.65 × 12.5% = 1.84% + 8.13% = 9.97%. Even that is above the current 9.55%, so the board should not force gearing higher simply to lower WACC.
Why not the full buyback
It takes interest cover to 3.4x, risks a downgrade and leaves little room for an EBIT downturn. It also signals that the company has no better use for cash.
Alternative
A special dividend returns capital without permanently reducing the share count and avoids the signal that the shares are undervalued. If the activist wants a buyback, offer a £100m buyback plus a £50m special dividend, and use the remaining cash for network investment. Communicate that the board will review capital returns annually against a leverage target of 2.0x–2.5x net debt/EBITDA and an investment-grade rating.
