What caused AOS's Q2 earnings crash?

AOS's Q2 earnings crash was likely caused by a combination of factors:

1. **Decline in Water Heater Volumes**: The company's segmental earnings were down 12.5% year-over-year to $147.9 million, primarily due to lower water heater volumes. This decline suggests that AOS's core business is facing challenges, which is a key factor in the company's earnings performance.
2. **Market Conditions and Challenges**: The company has faced significant headwinds over the past year, including a substantial 1-year change with a decline of -25.82%. These market challenges likely impacted AOS's ability to generate earnings in Q2.
