TTM profit swings and one off loss

• Over the last twelve months, Coherent reported US$6.6b of revenue and net income excluding extra items of US$400.6 million, alongside a one off loss of US$147.6 million that weighs on the reported earnings picture.
• What stands out for the bearish narrative is that this large one off loss sits next to forecasts for earnings to grow around 36.4% per year. This creates a gap between the recent profit record and the longer earnings history.
  • Bears highlight that five year earnings have declined about 16.6% per year, so the current US$400.6 million of trailing net income and the recent move back into profitability do not erase that longer track record.
  • The combination of a sizeable one off charge and a relatively short period of profitability gives cautious investors reasons to question how firmly the current earnings base is established.

Skeptics point to the one off loss and uneven earnings record as signs this recovery could be fragile, while others see it as a reset before steadier profit growth, and that tension is at the heart of the bearish narrative for Coherent. 🐻 Coherent Bear Case

Revenue near US$1.8b and growth forecasts

• On a trailing basis, revenue sits at US$6.6b compared with quarterly revenue of US$1.81b in Q3 2026, and analysts are forecasting around 23.8% yearly revenue growth and 36.4% yearly earnings growth over the next period referenced.
• Supporters of the bullish narrative point to this combination of current revenue scale and high forecast growth as evidence that Coherent's photonics and AI data center exposure could translate into stronger financial results.
  • Bulls argue that record bookings tied to AI data center build outs and high speed optics could help sustain the kind of growth implied by the 23.8% revenue and 36.4% earnings forecasts.
  • At the same time, the company has already reported three consecutive quarters in 2026 with net income excluding extra items between about US$145.1 million and US$192.9 million, which is used to support the view that earnings are starting from a meaningful base.

Bulls point to strong AI related demand and recent profits as a springboard for the high growth forecasts that underpin their narrative for Coherent. 🐂 Coherent Bull Case

Rich valuation multiples versus industry

• At a current share price of US$319.19, the stock trades on a P/S of 9.5x compared with 2.6x for the US Electronic industry and 5.5x for peers, and it sits above an indicated DCF fair value of about US$297.61.
• Consensus narrative commentary that expects earnings to grow quickly and margins to rise is partly challenged by these valuation markers, because the market is already paying more per dollar of sales than both the industry and peer averages.
  • Analysts who see a balanced case reference high forecast growth and recent profitability, but the gap between the current price and the DCF fair value, as well as the higher P/S versus peers, suggests expectations are already demanding.
  • Recent shareholder dilution and higher share price volatility over the last three months add another layer for investors to weigh when thinking about how much of the future growth story is already embedded in the current valuation.
