S&P upgrades Viavi Solutions rating to BB on debt repayment

S&P Global Ratings upgraded Viavi Solutions to BB from B+ after the company repaid all term loan B borrowings using proceeds from its $575 million May 2026 equity raise. S&P now expects adjusted debt/EBITDA to improve to 2.8x by fiscal 2026 year-end from a prior 5.5x estimate, and further to 2.2x in fiscal 2027, with free operating cash flow projected at $60 million to $70 million in fiscal 2026 and $160 million to $170 million in fiscal 2027. The outlook is stable, supported by roughly $200 million of annual run-rate revenue from Spirent assets and strong data-center-related demand.

Analysis

The bigger signal is not the rating action itself, but the de-risking of the capital structure into a cleaner equity story. With debt now effectively out of the way, Viavi’s incremental operating leverage should translate much more directly into equity value, especially if hyperscaler demand is as durable as implied. That makes the stock more sensitive to small changes in top-line growth than it was a quarter ago — a useful setup if the market still prices it like a leveraged integration story rather than a self-funding growth asset.

The second-order winner is likely the broader optical and data-center supply chain: if Viavi is seeing demand inflect from hyperscalers, optical module vendors and silicon suppliers are likely further along the same curve. That tends to pull forward orders across the stack, but it also raises the risk of a short-cycle inventory build if customers are over-ordering ahead of a capacity expansion cycle. In that case, the benefit to Viavi could be multi-quarter, while the rest of the chain may see a sharper but shorter pulse.

The key risk is that the leverage reset may cause the market to extrapolate too aggressively from a one-time cleanup event into a smooth rerating path. The equity story still depends on integration execution and on whether the data-center mix improvement is structural rather than a temporary replenishment cycle; any slowdown in hyperscaler capex over the next 6-9 months would hit expectations quickly now that leverage is lower and investor patience is likely shorter. The contrarian view is that the market may be underestimating how much of the upside is already mechanically baked in from deleveraging, leaving less room for multiple expansion unless organic growth keeps surprising.

Key Decisions for Investors

• Long VIAV on a 3-6 month horizon if it has not yet fully rerated on the balance-sheet cleanup; target a move toward growth-equity multiples rather than distressed hardware multiples, with the main risk being a hyperscaler capex pause.
• Use VIAV call spreads instead of outright equity if entering after the initial headline reaction: limited premium outlay, defined downside, and better convexity if the market re-rates the name over the next 1-2 quarters.
• Pair long VIAV / short a higher-beta networking or component peer that still carries leverage or more cyclical exposure; thesis is that de-levered execution should outperform a similar-growth but more fragile balance sheet.
• Add a catalyst watch on any hyperscaler capex commentary over the next earnings season; if order momentum confirms, the trade can be held for 2-3 quarters, but if capex guidance softens, reduce quickly because the equity is now less protected by the capital structure.
