Summary

First Solar's Chief Technology Officer, Markus Gloeckler, executed a sale of common stock on March 16 that totaled $73,894. The sale followed the vesting of restricted stock units earlier that week. Around the same time, the company issued quarterly results and forward guidance that prompted several analyst firms to revise ratings and price targets.


Insider transaction details

According to a Form 4 filing with the Securities and Exchange Commission, Markus Gloeckler sold 368 shares of First Solar common stock on March 16 at $200.8 per share, for gross proceeds of $73,894. The filing notes that the sale came after restricted stock units vested on March 13, when Gloeckler acquired 854 shares at a $0 purchase price.

After completing the March 16 sale, Gloeckler is reported to directly own 10,348 shares of First Solar stock.


Market context

At the time of the transaction, First Solar was trading at $200.42, a level very close to the CTO's sale price. Independent analysis cited in company commentary indicates the shares appear undervalued based on Fair Value calculations, placing the stock among undervalued opportunities within the solar sector. The company trades at a price-to-earnings ratio of 14.1, and noted commentary also highlights that the stock has experienced notable price volatility.


Analyst reaction to financial disclosures and guidance

First Solar reported fourth-quarter earnings that missed expectations by 6% and were 5% below Deutsche Bank's estimates. The company issued 2026 revenue guidance of $4.9 billion to $5.2 billion, which was 17% below Street expectations and implies a 3% year-over-year revenue decline.

Those results and the guidance prompted multiple analyst adjustments:

  • Deutsche Bank downgraded the stock to Hold from Buy and reduced its price target to $245 from $300.
  • GLJ Research downgraded First Solar to Hold from Buy, citing the 2026 guidance as a significant miss across revenue, volumes, and EBITDA.
  • Guggenheim lowered its price target to $269 from $312 while maintaining a Buy rating.
  • Barclays reduced its price target to $228 from $279 and maintained an Overweight rating.
  • Jefferies cut its target to $205 from $260 and retained a Hold rating.

Implications

The insider sale itself follows a routine vesting event and left the CTO with 10,348 shares. Concurrently, the firm's recent earnings and 2026 guidance revisions have led to material changes in analyst views and price targets, reflecting market reassessment of near-term revenue and profitability expectations.


Key takeaways

  • CTO Markus Gloeckler sold 368 shares on March 16 at $200.8, netting $73,894 after an RSU vesting on March 13.
  • First Solar's share price near the sale was $200.42, and the company has a P/E ratio of 14.1 amid noted volatility.
  • Multiple brokerages adjusted ratings and price targets after Q4 results and 2026 guidance that fell short of consensus.
