AI Spending Boom Slows Stock Buybacks' Impact on Earnings Per Share
Corporate stock repurchases have long boosted earnings per share by reducing the number of shares outstanding, but this benefit is diminishing as companies increasingly redirect cash toward capital expenditures for AI infrastructure. Despite record buyback spending, total share counts in the S&P 500 are rising due to new stock issuance from employee compensation and acquisitions—particularly prevalent among Big Tech firms like Alphabet (GOOGL), Amazon (AMZN), Meta (META), Microsoft (MSFT), and Oracle (ORCL). As AI investments consume more of corporate cash flow, buybacks have fallen to about 31% of earnings. This shift is reducing the financial flexibility for companies to reward shareholders through share repurchases. The capital expenditure boom mirrors past infrastructure overbuilds like those in the dot-com era, where heavy upfront spending outpaced returns and led to poor investor outcomes. Analysts warn that AI builders may face similar risks if demand lags behind investment costs or if end users capture more value than providers. Investors are advised to monitor key financial metrics such as operating cash flow versus capital expenditures, revenue growth relative to depreciation, and changes in diluted shares outstanding. The implications for the stock market could be significant: reduced buyback activity may dampen earnings per share growth, which has been a major tailwind for equity valuations. As companies like Alphabet plan large stock sales to fund AI expansion, investors must assess whether these investments will generate sufficient returns or lead to overcapacity and financial strain.
