Pomerantz LLP, a US-based securities litigation firm, has recently announced an investigation on behalf of investors of First Solar, a US-based solar module manufacturer. The investigation concerns whether the officers or directors from First Solar were involved in securities fraud or unlawful practices. The announcement followed a January 7, 2026 analyst downgrade by Jefferies, which lowered the rating to Hold from Buy. The analyst cited reduced guidance, margin compression, and significant de-bookings during 2025. The analyst also stated that First Solar’s deployment opportunities could be more limited during 2026. Following this assessment, First Solar’s share price fell $27.67, representing a 10.29% decline. The stock closed at $241.11 per share on January 7, 2026, reflecting investor reaction. Pomerantz LLP has advised investors to contact the firm regarding potential claims.
