Gap to fair value
−27%

In our model the price counts as cheap below $269.07 and expensive above $807.20 (uncertainty very high, based on the price swings of the past year).

The two parts of the fair value come to $661.36 (cash-flow model) and $145.84 (industry comparison), and the gap between them shows how uncertain the estimate is.

Calculated with a cost of equity of 9.3%. At 10.3% the fair value would be $344.35, at 8.3% it would be $489.98.

Company outlook raised

Share price after the results: −9.4%

Full year revenue guidance midpoint was raised by $120 million to $6.42 billion and adjusted gross margin for the year by 50 basis points.

Supporting passage from the call, verbatim
“In Q4 26, we expect to deliver of $1.75 billion plus or minus $50 million, raising the full year midpoint to $6.42 billion, up $120 million from last quarter. With this revenue guide, we expect to increase our market share in the combined optical systems and plug market by about 4 points to approximately 30%.”

The outlook is not part of the score and not a recommendation to buy or sell.
