What impact will the new debt have on the company's weighted average cost of capital (WACC) and overall valuation?

Impact on WACC

The $750 mm senior‑note issuance adds a sizable, but still modest, layer of debt to Novelis’ capital structure. Assuming the notes trade at roughly the same yield as comparable 10‑year aluminum‑industry senior unsecured bonds (≈4.5‑5.0 % nominal) and that the company’s marginal tax rate stays near 21 %, the after‑tax cost of this new debt will be about 3.6‑4.2 %. If the pre‑issue weighted‑average cost of equity is still in the 8‑9 % range, the blended cost of capital will fall slightly because the new debt is cheaper than equity. In other words, the added leverage should lower Novelis’ WACC modestly, provided the company can service the interest with existing cash flow (interest coverage > 3× is typical for the sector).

Impact on Valuation

A lower WACC translates into a higher present‑value of future cash flows in a discounted‑cash‑flow (DCF) model, nudging the intrinsic enterprise value upward. However, the net effect is tempered by two countervailing forces:

1. Dilution of equity value – the new debt increases the enterprise value (EV) denominator, but the cash‑in‑hand from the notes is added to assets, so the equity value (EV – net debt) rises only by the amount of net proceeds after issuance costs. If the proceeds are earmarked for value‑creating projects (e.g., capacity expansion, recycling technology upgrades, or strategic acquisitions) that lift operating margins, the upside to equity valuation can be material.
   
2. Credit‑risk perception – The market will re‑price the stock based on the perceived ability to meet the new interest obligations. If analysts view the capital raise as a prudent, low‑cost financing move, the stock may see a small positive price reaction; if they fear over‑leverage, the price could face pressure.

Actionable Take‑aways

• Short‑term: Watch the bond‑yield spread and the stock’s reaction over the next 1‑2 weeks. A narrowing spread (bond price rally) alongside a modest stock uptick suggests the market is comfortable with the added leverage.
  
• Medium‑term: Track the use of proceeds—capex announcements, acquisition filings, or margin‑improving initiatives. Positive deployment will reinforce the WACC reduction and support a higher equity multiple.
  
• Positioning: If the notes are priced at a discount to comparable peers and the company’s credit rating remains stable, a long‑biased stance on Novelis’ equity could be justified, especially if you anticipate the debt to fund higher‑return projects that lift free cash flow and compress the WACC further. Conversely, if credit metrics (e.g., debt/EBITDA) start to creep upward, consider tightening exposure.
