Near Term

Reciprocal Tariffs:

Industry Uncertainty

"Universal" and "reciprocal" tariff rates create significant operational uncertainty

First Solar's contracted backlog for imported product contains tariff-related risk mitigation provisions

Pivoting India manufacturing to domestic market and evaluating Malaysia and Vietnam 2025 production volume

Trade and Industrial Policy

Uncertain impacts of Congressional budget reconciliation on renewable energy tax credits

Final Southeast Asia AD/CVD determinations confirm dumping and illegal subsidization, levy substantial duties

Chinese producers relocate capacity, data indicates surge in U.S. imports, including from Laos and Indonesia

Longer Term

Utility-Scale Solar: Strong Fundamentals

Projected U.S. electricity demand growth of 50% by 2050

Artificial Intelligence, reshoring domestic manufacturing expected to be key drivers

Utility-scale solar capable of rapidly delivering cost-effective incremental peaking and baseload capacity

Domestic Manufacturing Ecosystem

Policy uncertainty and imposition of tariffs may delay c-Si manufacturing investments in U.S.

Timing of IRA §45X credit phase-out limits potential benefits to facilities not yet operating

FEOC regulations, high reliance on bill of material imports pose further headwinds to c-Si manufacturing in U.S.

First Solar

Long-Term Strength

America's Solar Company: American technology, American manufacturing, American supply chain

14 GW of vertically-integrated domestic operational capacity by 2026 provides supply certainty

Tangible economic value creation and retention through domestic manufacturing, supply chains

Policy

Risks of policy uncertainty in Europe, India and the United States

Especially with regards to tariffs, and the ongoing budget reconciliation process and its related potential impacts on the IRA

Risks of policy uncertainty in Europe, India and the United States, especially relating to the budget reconciliation process and IRA, remain

Policy impact and uncertainty relating to tariffs has increased significantly

Tariff impact on guidance range

Section 232 tariffs on aluminum and steel imports into the U.S. at a rate of 25%

Upper end: Assumes impacts from the tariff policy in place as of today's call

remaining through at least the end of 2025

Lower end: Assumes the above, with the addition of including the impacts from

the assumption that "reciprocal" tariffs take effect as of July 9th, 2025

Tariff cost impacts to full year guidance

Section 232 tariffs approx. $15M to $30M

Volume and ASP changes approx. $100M to $375M

Import duties on finished goods approx. $90M to $70M

Raw material imports approx. $25M to $55M

Period costs (sales freight, warehousing, ramp, underutilization, and other) approx. $65M to $270M

Temporary idling of production in Malaysia and Vietnam provides optionality pending tariff, budget reconciliation, IRA updates

"From a second quarter earnings cadence perspective, we anticipate our module sales to be between 3.0 and

3.9 GW. We forecast our advanced manufacturing production tax credit

available to us under Section 45X of the

Internal Revenue Code ("Section 45X tax credit"), to be between $310 million and $350 million in the second quarter.

© 2025 Copyright First Solar, Inc.

These factors result in forecasted second quarter earnings per diluted share between $2.00 and $3.00."
