First Solar, Inc. Announces First Quarter 2024 Financial Results

•Net sales of $794 million

•Net income per diluted share of $2.20

•Net cash balance of $1.4 billion

•Maintain full-year 2024 P&L guidance

•YTD net bookings of 2.7 GW with an average selling price (“ASP”) of 31.3 cents per watt, excluding adjusters

•Expected sales backlog of 78.3 GW

TEMPE, Ariz., May 1, 2024 –First Solar, Inc. (Nasdaq: FSLR) (the “Company”) today announced financial results for the first quarter ended March 31, 2024.

Net sales for the first quarter were $794 million, a decrease of $0.4 billion from the prior quarter. The decrease was primarily driven by an expected historical seasonal reduction in volume of modules sold.

The Company reported first quarter net income per diluted share of $2.20, compared to net income per diluted share of $3.25 in the fourth quarter of 2023.

Cash, cash equivalents, restricted cash, restricted cash equivalents, and marketable securities, less debt at the end of the first quarter, decreased to $1.4 billion from $1.6 billion at the end of the prior quarter. The decrease was primarily a result of capital expenditures related to manufacturing capacity expansions in Alabama, Louisiana, and Ohio.

“We are pleased with our start to 2024, with good operating performance, selective bookings with a year to date ASP over 31 cents per watt excluding adjusters, and solid financial results,” said Mark Widmar, CEO of First Solar. “Our differentiated technology and balanced business model are enabling us to drive growth, navigate industry volatility and deliver enduring shareholder value”.

Operating Expenses (1) (3)	$455M to $485M	Unchanged
Operating Income (1) (4)	$1.5B to $1.6B	Unchanged

——————————

(1)From an earnings cadence perspective, we anticipate our net sales and cost of sales profile, excluding the advanced manufacturing production credit available to us under Section 45X of the Internal Revenue Code (“Section 45X tax credit”), to be approximately 35-40% in the first half of the year and 60-65% in the second half of the year. We forecast Section 45X tax credits of approximately $400 million in the first half of the year and $620 million in the second half of the year. With an operating expenses profile roughly evenly split across the year, this results in a forecasted earnings per share profile of approximately 35-40% in the first half of the year and 60-65% in the second half of the year.

(2)Assumes$40 million to $60 million of ramp costs and $1.0 billion to $1.05 billion of Section 45X tax credits

(3)Assumes $85 million to $95 million of production start-up expense

(4)Assumes $125 million to $155 million of production start-up expense and ramp costs, and $1.0 billion to $1.05 billion of Section 45X tax credits

(5)Defined as cash, cash equivalents, restricted cash, restricted cash equivalents, and marketable securities, less expected debt at the end of 2024

The guidance figures presented above are forward-looking statements that are subject to a variety of assumptions and estimates, including with respect to certain factors related to the Inflation Reduction Act of 2022 (the “IRA”). Among other things, such factors include (i) the total Section 45X tax credit and (ii) the timing and ability to monetize such credit. Investors are encouraged to listen to the conference call and to review the accompanying materials, which contain more information about First Solar’s first quarter 2024 financial results, 2024 guidance, and financial outlook.
