Lumentum (NASDAQ: LITE) is AI-critical for its connectivity, specifically optical and photonic, and its ability to break the data bottleneck. Its importance to the industry was evident in the fiscal Q4 2026 results, which reflected strength relative to a high bar, improved guidance, and accelerating profitability. Profitability is a crucial element, as many other AI-critical names have impaired their cash flow as they ramp up AI spend.
While Lumentum is accelerating its investments too, it doesn’t have the capital requirements of a hyperscaler, a neocloud operator, or a start-up trying to scale. What it does have is the capacity to improve its balance sheet and set the stage for share buybacks.
