VIAVI Solutions benefits from every fight in the interconnect layer, since copper versus optical and pluggable versus co-packaged all raise test intensity whoever wins. Its quarter beat cleanly: revenue rose 52.5% to $443.1 million, operating margin expanded 960bp to 24%, and Q1 EPS guidance of $0.40-0.42 crushed the $0.28 estimate. The test segment grew 69.2%. CEO Oleg Khaykin called CPO delay fears nonsense, saying yield issues mean more testing, with CPO revenue starting this quarter. x.com  … Show more

Viavi Solutions is a huge beneficiary of 1.6T tailwinds and appears to have shown 3.2T test gear at OFC 2026. x.com 

Viavi looks expensive against its cash earnings: at 23x, versus the 11x its industry usually gets, it trades 77% above the high end of a $17.76–$22.60 fair range. That range is 11x next year's cash earnings, give or take 12%, and leans on a forecast 69% above trailing earnings. This is a valuation read only, with no fundamental work. x.com 

VIAVI is a picks-and-shovels winner as AI data-center optical testing becomes its main growth driver. Revenue rose 42.8% to $406.8M on data-center and aerospace and defense demand, non-GAAP EPS jumped 80% to $0.27 with a 21% operating margin, and its network and service enablement segment grew 54.4% as Spirent contributes. Next-quarter guidance calls for $427-437M of revenue. The photonics buildout needs high-volume test and measurement, and data-center capex is surging. x.com  x.com 

Viavi's AI data-center testing business is running ahead of plan. Q4 revenue of $443.1M and a 24.0% operating margin topped the high end of guidance, data center more than doubled year over year excluding Spirent, and the Q1 guide of $450M-$460M and $0.40-$0.42 EPS beats a $432M and $0.28 street. The $500M quarter moved up to calendar 2027 from fiscal 2028. CEO Oleg Khaykin called CPO yield-delay worries nonsense, since yield problems mean more testing, with CPO revenue starting this quarter. … Show more

Viavi's earnings were incredible, with revenue up 52.5% to $443.1M and non-GAAP operating margin rising to 24.0% from 14.4%. Non-GAAP EPS jumped to $0.34 from $0.13, which should drive a huge day for the stock. x.com 

Silicon photonics and co-packaged optics are clearly what's next, and the market is rewarding accelerating revenue growth. Some timelines may slip and a 20% pullback is possible, but holding legitimate parts of the value chain for three years should push these stocks to laughable valuations. x.com 

Viavi Solutions can reach $90-$100 by 2028 as earnings scale and it keeps its rerating as an AI hardware enabler. It once traded at 13-16x forward earnings as slow-growth telecom instrumentation, but now trades near 38x 2027 estimates. Consensus non-GAAP EPS rises from about $0.94 in FY2026 to $1.83 by FY2028, and a bull case with stronger Spirent synergies reaches $2.25-$2.50. As a premier testing bottleneck for 1.6T and 3.2T optical deployments, it can sustain a 38-40x multiple. x.com 

Credo is one of the cheapest AI growth stocks, trading around 26x forward earnings after a hard correction while revenue grew 115% to $479M and full-year growth is guided above 85%. Margin worries mostly reflect DustPhotonics amortization and stock comp; non-GAAP gross margin held near 68%. DustPhotonics adds a second engine in optics, with over $600M expected this year, and Credo's low-laser designs can ship through the laser shortage. One customer at about a third of revenue is the main risk. … Show more

Coherent has the most substance in the optical group and the only real base on its chart, while the sector's sell-off is macro, not fundamental. At about 23x 2027 estimates it looks mispriced, and it is the only company holding 6-inch InP, silicon photonics, OCS and CPO engines at once. It alone has stopped making lows. Rate-hike pricing and a 5.04% 10-year are still compressing optical multiples, so staged, defined-risk entries beat full commitments; a daily close below 264 invalidates it. … Show more
