First Solar Q1 Beats, Reaffirms 2026 Guidance; Policy Risk Remains Key

What happened

First Solar reported Q1 2026 net sales of $1.04 billion, up 24% YoY, and net income of $347 million, exceeding consensus expectations. The company reaffirmed its 2026 guidance for 17.0-18.2 GW shipments, $4.9-$5.2 billion in net sales, and $2.6-$2.8 billion in adjusted EBITDA, which continues to embed $2.10-$2.19 billion in Section 45X credits. While the strong start and reaffirmation provide near-term visibility, the earnings bridge remains heavily dependent on successful monetization of 45X credits at observed clearing prices near $0.955 per $1. The stock rose approximately 6% on the news but still trades near $202, within the prior WAIT range of $175-$240. The key catalyst to watch is Q2 results, which must deliver the guided $330-$400 million in 45X credits and 3.4-4.0 GW in shipments to sustain confidence in full-year targets.

Implication

First Solar's Q1 results and reaffirmed guidance are consistent with the base case scenario, but the stock remains a WAIT given the concentrated profit driver from Section 45X credits. Investors should monitor Q2 2026 for three proof points: (1) 45X credit realization within the $330-$400 million band, (2) shipment volumes in line with 3.4-4.0 GW, and (3) any updates on credit transfer pricing relative to the ~$0.955 per $1 benchmark. Until these are confirmed, the bear case (25% probability) of a 45X shortfall or trade policy erosion keeps the downside to $140 alive. The bull case (20% probability) requires 2H26 South Carolina facility ramp and sustained credit monetization. Recommended action: trim into strength above $240, consider adding at $175 or below on policy clarity, and reassess after Q2 earnings.

Thesis delta

No material shift in the investment thesis. The Q1 results and reaffirmed guidance strengthen the base case probability slightly but do not resolve the binary risk from 45X credit eligibility and trade policy. The WAIT rating remains appropriate, with conviction unchanged at 3.5 out of 5. Investors should continue to watch Q2 execution as the next pivotal checkpoint.
