Cummins' AI Power Growth Masks Underlying Cyclical and Hydrogen Risks

What happened

Cummins is experiencing a divergence where robust data-center power demand fuels double-digit growth in Power Systems and Distribution, offsetting persistent weakness in its truck engine business due to a prolonged North American freight recession. A Seeking Alpha article projects FY 2026 revenue growth of 3-8% and EBITDA margin expansion to 17-18%, reinforcing a bullish narrative centered on AI-driven opportunities. However, the DeepValue master report cautions that the stock's 54% surge over the past year to $552.09 embeds excessive optimism, with valuations at 28.5x EPS pricing in peak-like margins and underappreciated cyclical risks. Recent filings show Power Systems revenue up 18% with 22.9% EBITDA margins in Q3 2025, but Accelera's hydrogen segment incurred a $336 million loss, including a $240 million impairment, leading to scaled-back ambitions. This dynamic underscores Cummins' reliance on cyclical AI power demand while grappling with structural challenges in its core engine franchise and clean-energy ventures.

Implication

The bullish growth projections for Power Systems must be critically assessed against risks of margin compression from increased competition and evolving data-center capex cycles, which could undermine earnings sustainability. Persistent losses in Accelera and a multi-year truck engine slump threaten to erode profitability, making the stock vulnerable to multiple compression given its elevated P/E ratio of 28.5x. Strong free cash flow and a growing dividend provide some downside protection, but the balance sheet strength does not fully offset overvaluation concerns in a crowded market narrative. Monitoring the 2026 guidance update and Accelera's strategic review will be crucial for signaling whether current profitability levels can be maintained amidst these headwinds. Therefore, aligning with the DeepValue report, investors may consider patience for a more attractive entry point near $450 to mitigate risks of capital loss from overoptimistic pricing.

Thesis delta

The Seeking Alpha article reinforces the growth story but does not shift the DeepValue thesis, which maintains that Cummins is overvalued relative to cyclical truck engine headwinds and hydrogen restructuring risks. A change to a more bullish stance would require concrete evidence of sustained Power Systems margins above 20% and a clear, profitable path for Accelera, neither of which is yet apparent.
