Is earnings growth masking a cash flow problem for tech companies?
Core argument: S&P 500 earnings per share have outpaced free cash flow over a sustained period, a divergence that began with pandemic-era cost cuts and accelerated sharply after ChatGPT’s launch.
Questions are mounting over how quickly the capex ploughing into AI will translate into profitability, but tech’s earnings growth is still impressive — it’s just that the cost of that investment is increasingly hard to ignore. Their free cash flow is deteriorating at an unprecedented pace as spending on data centres gobbles it up, even as the rest of the corporate sector generates more cash. The numbers for the overall S&P 500, as shown by Bloomberg’s Graph Fundamentals function, confirm a protracted run in which earnings per share have risen much faster than free cash flow. This started after companies had made big pandemic cost cuts and then went into overdrive after the arrival of ChatGPT.
