After a very strong 319.5% return over the past year, Viavi Solutions now screens as undervalued on market multiples, while its broader valuation checks point to a more mixed picture. This puts the recent share price surge under closer scrutiny.
Viavi Solutions has delivered a 319.5% return over the last 12 months, so recent buyers are effectively paying up after a sharp rerating.
Expectations around AI driven data center and optical networking demand can support optimism on revenue potential. Any slowdown in hyperscale data center buildouts or spending by customers like Nokia and Ciena may challenge those assumptions.
The stock is assessed as undervalued on certain metrics, but with a valuation score of 3 out of 6, the overall assessment is a mixed picture rather than a clear bargain or clear overvaluation.
The issue now is whether Viavi Solutions’ current valuation adequately reflects both the AI driven upside in its networking business and the risks if those growth expectations ease.
Does Viavi Solutions Look Undervalued on Sales?
P/S is a useful lens for Viavi Solutions because investors are focusing on its revenue exposure to AI driven networking and data center spending. Right now, Viavi Solutions trades on a P/S of 7.7x, which is higher than the broader communications industry average of 2.3x and slightly below the peer group average of 8.0x.
On a more tailored view that factors in Viavi Solutions’ business mix, margins, size and risks, the model points to a fair P/S ratio of 11.1x. That sits well above the current 7.7x level, which suggests the stock screens as undervalued on this measure even after the strong share price move. Despite recent optimism around AI driven data center demand, the P/S multiple does not yet match the fair ratio indicated by these fundamentals.
Put together, Viavi Solutions appears undervalued on the P/S multiple relative to its modelled fair ratio.

The Bottom Line
Viavi Solutions screens as undervalued on its tailored P/S multiple, even after a very strong 1 year return, but the broader valuation checks point to a more cautious, mixed picture rather than a clear disconnect. The key question is whether AI driven data center and optical networking demand can support the revenue profile implied by that multiple without stalling. For now, the crux of the bull versus bear debate is whether current expectations for hyperscale and telecom spending prove resilient, or whether any slowdown shows that the apparent discount is simply compensation for execution and customer concentration risk.
