With the headline numbers on the table, the next step is to see how these results line up with the widely followed growth and risk narratives around Lumentum and where those stories might need updating.

TTM Net Income Rebounds To US$439 Million

• On a trailing twelve month basis, net income moved from US$25.9 million at Q4 2025 to US$439 million at Q3 2026, alongside revenue rising from US$1.6b to US$2.5b.
• What stands out for the bullish narrative is how this profit swing lines up with forecasts that earnings could grow around 76.3% per year. However, five year trailing earnings had declined 33.1% per year, so the recent US$439 million result sits at the optimistic end of that story while still leaving a short track record for the higher margin phase.

Bulls argue that this kind of earnings step up could justify higher expectations if it proves durable. They focus on how quickly net income has shifted from losses in 2025 to the current US$439 million TTM figure, and how that may support their view of faster EPS expansion than the longer term decline would suggest. 🐂 Lumentum Holdings Bull Case

Revenue Almost Doubles In Six Quarters

• Total revenue in the regular quarterly data runs from US$402.2 million in Q2 2025 to US$808.4 million in Q3 2026, with the trailing twelve month revenue increasing from US$1.4b at Q2 2025 to US$2.5b at Q3 2026.
• Bears point out that even with this revenue climb, five year earnings had fallen 33.1% per year and price to sales sits at 27.2x versus 12.2x for peers and 2.6x for the wider US Communications group. They see the current growth as needing to work against both that longer earnings decline and a relatively high revenue multiple.
• This tension shows up in the trailing twelve month figures, where US$2.5b of revenue and US$439 million of net income coexist with a P/S that is more than double the peer average.
• It also means that if revenue growth were to slow from the recent pace, the earlier earnings decline and higher multiple context would weigh more heavily on the bearish view.

Skeptics argue that this combination of strong recent growth and a 27.2x P/S multiple leaves less room for disappointment than the five year earnings decline might justify. This is why they focus so closely on how sustainable the move from US$1.4b to US$2.5b of trailing revenue really is. 🐻 Lumentum Holdings Bear Case

Price Sits Between DCF And Analyst Targets

• With the current share price at US$944.28, investors are looking at a DCF fair value of US$1,591.40 and a single allowed analyst price target of US$1,081.10, so the stock trades below that DCF figure and closer to the analyst level while carrying a 27.2x P/S versus 2.6x for the industry.
• Consensus style commentary highlights this as a mixed picture, where the gap to the DCF fair value backs the idea of undervaluation, yet the premium P/S multiple and higher recent share price volatility relative to the US market temper that by reminding investors that the market is already paying a higher revenue multiple while weighing the recent return to profitability.
• The fact that US$944.28 sits between the DCF fair value of US$1,591.40 and the US$1,081.10 target illustrates why some see upside based on cash flow models while others focus on the elevated P/S.
• Overlaying this with the move from a trailing twelve month loss of US$522.8 million at Q2 2025 to TTM profit of US$439 million at Q3 2026 gives both sides concrete numbers to support either an upside or a more cautious stance.
