Share-Count History — From CAT Annual Filings
What Dilution Means for CAT Shareholders
Dilution refers to the reduction in existing shareholders' percentage ownership when a company issues new shares. Companies dilute for multiple legitimate reasons — funding growth, acquiring other companies, compensating employees with equity, or converting debt to equity. Whether dilution is good or bad depends on what the new capital is being used for and whether per-share value grows faster than the share count. For CATERPILLAR INC, share count went from 547,471,467 on 2021-06-30 to 468,478,923 on 2025-06-30 — a change of -14.4% over approximately 49 months.
The dilution mechanism shareholders should monitor most closely is the presence of an ATM (at-the-market) equity facility. ATMs give the company standing authority to issue new shares into the open market at any time, often without separate shareholder notice. They create continuous-issuance overhang — even days when no new shares are sold, the facility itself weighs on the stock as supply might appear at any moment. CATERPILLAR INC's most recent annual filing does not mention an ATM facility — though that status can change with each new financing round.
Convertible notes are a separate forward-dilution mechanism: each note converts into shares at a defined price (or formula) at maturity, automatically expanding share count. The presence of large convertible-note balances on the balance sheet — even before conversion — is a material signal that future dilution is contractually scheduled. No convertible notes are mentioned in CATERPILLAR INC's most recent annual filing.
