Market Theme: Assessing the Level of Debt-Funded CapEx

  • Recent increases in corporate debt—where issuance is up more than 26% YTD—have raised concerns about the sustainability of CapEx funded by external borrowing, particularly against the backdrop of rising Treasury yields.
  • We examine debt ratios for the S&P 500 and its Information Technology sub-sector. Even with accelerating CapEx, free cash flow per share is rising at a faster pace for the Information Technology sector than for the S&P 500 as a whole, with higher returns on capital as well.
  • While net debt to EBITDA has been rising for the Information Technology sector, this ratio is still well below the ratio for the entire S&P 500. Moreover, a median free cash flow coverage ratio of nearly 15x points to substantial capacity to meet interest obligations from internally-generated cash flow.
