Q3 Earnings Beat Estimates While 10-Year Treasury Yields Climb Above 4.2 Percent

Third-quarter results released through October 2024 show S&P 500 companies exceeding consensus EPS estimates by 4.8 percent, led by technology and communication services sectors. Data from FactSet indicate aggregate revenue growth of 5.1 percent year-over-year, concentrated in firms reporting AI-related capital expenditures above prior guidance. This performance occurs against the 10-year Treasury yield rising from 3.8 percent in mid-September to 4.25 percent by late October, driven by persistent core PCE readings above 2.6 percent.

Rising yields directly affect firms with elevated net debt to EBITDA ratios above 2.5, increasing interest expense and compressing free cash flow available for buybacks. The original coverage understates the sector-level variation: mega-cap AI leaders maintain pricing power that offsets higher discount rates, while mid-cap software and hardware suppliers face margin compression once growth rates normalize below 15 percent. Primary earnings transcripts reveal repeated references to sustained capex commitments despite higher borrowing costs.

The Federal Reserve’s September dot plot projected two 25-basis-point cuts by year-end 2024, yet September CPI and October employment data have shifted market pricing to only one cut. This recalibration tightens financial conditions for issuers rolling over 2025 maturities. Forward P/E multiples for the S&P 500 Information Technology sector remain at 28.4 despite the yield increase, indicating limited immediate derating.

Next earnings season in January 2025 will test whether revenue guidance incorporates the higher cost of capital or whether firms continue to front-load AI infrastructure spending. Any downward revision in 2025 capex plans would signal that yield levels have begun to constrain the current investment cycle.
