HON vs PAYX: audited financials

  • Scale: HON's $37.4B of revenue is about 5.7× PAYX's $6.5B.
  • Net margin: PAYX kept 27.0% of revenue as net income versus 12.6% at HON.
  • Cash conversion: operating cash flow equalled HON 17.1% of revenue, or 1.36× net income; PAYX 39.3% of revenue, or 1.45× net income. A ratio well above 1× usually reflects non-cash charges or working-capital release; well below 1× can reflect working-capital build or non-cash gains.
  • Periods: the fiscal years end about 5 months apart (2025-12-31 for HON, 2026-05-31 for PAYX), so each figure reflects somewhat different demand and cost conditions.

The investment question

You now know HON reports about 5.7× PAYX's revenue, and PAYX keeps more of each dollar as net income. Those are the facts. The investment question is what each share price already assumes about their exposure to economic trends, and which evidence in the next filings would prove that assumption wrong.

SEC filing comparison and disclosure evidence

Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. HON's fiscal year ends December 31, while PAYX's ends May 31. Normalize the reporting periods before comparing growth, margins, capital intensity, or guidance.

The current verified House and Senate snapshot contains 28 matched transaction rows for HON and 31 matched transaction rows for PAYX. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you

This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.

A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
