Michael Koralewski, First Solar's Chief Supply Chain Officer, sold 264 shares on March 16 for $200.8 per share, netting $53,011, after receiving 640 shares via restricted stock unit vesting on March 13. The transaction comes amid a Q4 earnings miss and a 2026 revenue outlook that fell short of Street expectations, prompting multiple analyst price-target cuts and rating changes.

Key Points

  • Chief Supply Chain Officer Michael Koralewski sold 264 First Solar shares on March 16 at $200.8 per share, totaling $53,011, and had acquired 640 shares via RSU vesting on March 13 - relevant to corporate governance and insider activity monitoring.
  • First Solar’s Q4 results missed expectations by 6% and were 5% below Deutsche Bank estimates; 2026 revenue guidance of $4.9 billion to $5.2 billion was significantly below Street expectations and implies a 3% year-over-year decline - affecting investor sentiment and valuation assumptions.
  • Multiple brokerages adjusted views and price targets after the report: Deutsche Bank (Hold, PT $245 from $300), Guggenheim (Buy, PT $269 from $312), Barclays (Overweight, PT $228 from $279), Jefferies (Hold, PT $205 from $260), and GLJ Research (Hold from Buy) - impacting equity research and capital markets coverage for the solar sector.

Michael Koralewski, Chief Supply Chain Officer at First Solar, INC. (NASDAQ:FSLR), reported a sale of 264 company shares on March 16 at a per-share price of $200.8, resulting in proceeds of $53,011. The sale price was close to the then-current market quote of $200.42, and the solar panel manufacturer carries a market capitalization of $21.5 billion.

According to a Form 4 filed with the Securities and Exchange Commission, Koralewski also acquired 640 shares of First Solar common stock on March 13 as a result of restricted stock units vesting. The two filings together show both the automatic issuance of equity from compensation vesting and an executive sale executed a few days later.

Separately, InvestingPro analysis referenced in company disclosures indicates the stock appears undervalued at current levels based on a price-to-earnings ratio of 14.1. The InvestingPro platform is noted as offering nine additional ProTips for investors seeking further detail on FSLR.

First Solar recently reported fourth-quarter results that missed expectations by 6% and were 5% below Deutsche Bank’s estimates. The company provided 2026 revenue guidance in a range of $4.9 billion to $5.2 billion, a figure described as significantly below Street expectations and representing a 3% year-over-year decline.

In response to the earnings print and the 2026 outlook, multiple financial firms adjusted their views on First Solar's shares. Deutsche Bank downgraded its rating to Hold from Buy and lowered its price target to $245 from $300. Guggenheim trimmed its price target to $269 from $312 while retaining a Buy rating. Barclays reduced its price target to $228 from $279 and maintained an Overweight rating. Jefferies kept a Hold rating but cut its price target to $205 from $260, specifically citing weak guidance. GLJ Research moved the stock to Hold from Buy, calling attention to the company’s 2026 guidance as falling short across all metrics, including both revenue and EBITDA.

These developments - the insider sale following RSU vesting, the earnings shortfall, and the lower-than-expected 2026 revenue range - have coincided with a wave of analyst adjustments. The combination of executive transactions and revised market expectations highlights the near-term challenges First Solar faces in aligning its results and guidance with investor forecasts.


Context and implications

While the filings show standard compensation vesting and a subsequent executive sale, the company’s recent operating results and conservative guidance have driven changes in analyst sentiment and price targets. The reported P/E of 14.1 cited by InvestingPro provides one valuation lens cited by market participants evaluating the stock amid these revisions.

Risks

  • Revenue risk: First Solar’s 2026 guidance of $4.9 billion to $5.2 billion is significantly below Street expectations and implies a year-over-year decline, creating near-term top-line uncertainty for the solar manufacturing sector.
  • Earnings and analyst sentiment risk: The company’s fourth-quarter results missed expectations and several firms have reduced price targets or ratings, which may increase stock price volatility and affect investor demand in renewable energy and related markets.
  • Guidance and metric shortfalls: GLJ Research highlighted that 2026 guidance falls short across revenue and EBITDA, signaling potential downside to profitability metrics that matter to valuation models used by market participants.
