Top 5 Income Statement Red Flags

Identifying financial trouble early requires monitoring five specific income statement red flags. A sudden, severe decline in revenue growth often signals weakening demand, as seen in Zoom’s post-pandemic performance. Declining gross margins indicate pricing power issues or rising costs, exemplified by Beyond Meat’s shift into negative territory. Increasing sales and marketing expenses relative to revenue suggest diminishing returns on customer acquisition, a trend that preceded Peloton’s stock decline. Furthermore, goodwill write-downs, such as the $13.4 billion impairment charge taken by Teladoc Health, reveal past overpayment for acquisitions. Finally, excessive shareholder dilution—where share counts grow significantly faster than the business—erodes individual ownership stakes, a pattern observed in Twilio’s history. Tracking these metrics provides a clear diagnostic tool for assessing a company's long-term health and avoiding potential investment pitfalls.
