Family manufacturer considers a debt-funded share buyback
Ravensworth Engineering is a family-controlled UK manufacturer. The family owns 55% of the equity; the company has £80m EBITDA, £100m net debt and a £300m market capitalisation. It pays a modest dividend and has stable cash flows. A bank offers a £120m five-year term loan at 6.5% to fund a buyback at a 10% premium to the current share price. The existing covenant is net debt/EBITDA ≤3.0x. The finance director argues the buyback will lower WACC because debt is cheaper than equity and interest is tax-deductible at 25%. The family chair is concerned about losing financial flexibility and about the signal if the buyback is funded with debt. The company has £40m of undrawn facilities and no major debt maturities for three years. The buyback would be offered to all shareholders pro rata, but the family has said it will not sell.
1. Calculate pro forma net debt/EBITDA and covenant headroom after the £120m buyback. At what EBITDA decline would the covenant be breached? Assess whether the buyback is prudent.

Pro forma net debt is £100m + £120m = £220m. With EBITDA of £80m, net debt/EBITDA is 220 / 80 = 2.75x. The covenant is 3.0x, so the net-debt headroom is 3.0 × £80m − £220m = £20m. In EBITDA terms, the minimum EBITDA before breach is £220m / 3.0 = £73.33m, a fall of £6.67m or 8.3%. That is not a large cushion for a manufacturer with cyclical demand. The new loan adds £7.8m of annual interest before any existing interest, which further reduces resilience. The buyback is therefore not prudent at the full £120m unless the company can demonstrate highly stable cash flows and perhaps negotiate a higher covenant. A smaller buyback, funded partly from surplus cash or undrawn facilities, would preserve more headroom. The family's refusal to sell also means the buyback will increase the family's percentage ownership, reduce free float and may be perceived as entrenchment rather than a signal of confidence.
2. Estimate the impact on WACC using the numbers given and the Modigliani-Miller framework with tax. Explain why a lower WACC does not by itself justify the buyback.

Current D/E is £100m / £300m = 0.333. With rD = 6%, rE = 11% and tax = 25%, WACC = (100/400) × 6% × 0.75 + (300/400) × 11% = 1.125% + 8.25% = 9.375%. Unlever the cost of equity: 11% = rA + (1/3) × (rA − 6%) × 0.75, which gives rA = 10.0%. After the buyback, assume equity value falls by £120m to £180m, so D/E = £220m / £180m = 1.222. The new cost of equity is 10% + 1.222 × (10% − 6.5%) × 0.75 = 13.21%. New WACC = (220/400) × 6.5% × 0.75 + (180/400) × 13.21% = 2.68% + 5.94% = 8.63%. The WACC appears to fall by about 0.75 percentage points, but this calculation ignores distress costs, lost financial flexibility, the buyback premium and the possibility that the market re-rates the equity risk. A lower WACC is not a free gain: it reflects higher financial risk borne by shareholders. The board should use scenario analysis or adjusted present value, not a single WACC comparison, and should ask whether the buyback creates value after distress costs and family-control effects.
3. Compare the buyback with a special dividend and with retaining cash to reduce debt. Consider family control, signalling and financial flexibility.
Read the worked answer
A special dividend would distribute cash pro rata, preserving the family's 55% stake and avoiding a change in control or free float. It would still reduce equity and increase leverage, but the signal is more neutral than a buyback at a premium. Retaining cash to reduce debt would strengthen the balance sheet and preserve covenant headroom, which is valuable if demand weakens, but it may signal that the company lacks investment opportunities. A buyback at a 10% premium transfers value to selling shareholders and, because the family will not sell, increases family control; that may be efficient if the family can create value, but it also reduces liquidity and may entrench management. The debt-funded buyback is the most aggressive option and the least consistent with the chair's flexibility concern. My recommendation is either a smaller special dividend or a modest buyback funded from surplus cash, keeping pro forma net debt/EBITDA below about 2.0x. If the company proceeds with debt, it should stress-test EBITDA and explain how it would restore headroom without cutting investment.
