First Solar's Revenue Surge Masks Persistent Booking Fragility and Policy Dependency

What happened

A recent Motley Fool article contrasts GE Vernova's backlog growth with First Solar's $1 billion revenue increase in 2025, but this surface-level comparison overlooks critical underlying dynamics. First Solar's revenue jump is largely attributable to Section 45X manufacturing credits, which the DeepValue report identifies as dominating earnings power rather than organic demand or pricing strength. In FY2025, the company experienced net debookings of 0.9 GW, including a significant 6.6 GW termination due to customer breaches, exposing backlog fragility and counterparty risk. Looking ahead, FY2026 gross margin guidance of $2.5B to $2.6B relies heavily on $2.1B to $2.19B from 45X credits, highlighting a precarious dependency on policy monetization amid transfer-market uncertainties. Despite the revenue growth, investors must critically assess whether booking stability and credit durability can be sustained without further disruptions.

Implication

The revenue increase, while nominally positive, does not mitigate the core vulnerabilities outlined in the master report, such as the 6.6 GW termination and ongoing debooking trends. Investors should prioritize tracking quarterly net bookings and 45X credit monetization haircuts, as these will determine whether earnings power remains intact or deteriorates. Another breach-driven termination or a reduction in 45X eligibility below 15¢/W could trigger the bear case, compressing margins and undermining valuation assumptions. The company's strong balance sheet offers downside protection, but it does not eliminate earnings volatility when credits constitute over 80% of gross margin guidance. Therefore, adhering to the 'WAIT' rating and awaiting clearer evidence of booking recovery and stable credit sales is the prudent approach, as the current price of $243 already embeds optimistic policy outcomes.

Thesis delta

The article's mention of revenue growth does not shift the investment thesis; it merely confirms known financial improvements from the master report, which already highlighted FY2025 profitability gains. The thesis remains unchanged: First Solar's near-term fate hinges on observable variables like net bookings and 45X credit monetization, not headline revenue figures, and investors should wait for these datapoints to materialize before committing capital.
