Longanesi First Gas Sales Have Been Achieved

First Quarter 2025 and Recent Company Highlights:

DALLAS – May 15, 2025 – AleAnna, Inc. (“AleAnna” or “the Company”) (NASDAQ: ANNA) today announced financial results for the first quarter of 2025. While revenue from the Longanesi field production was not recognized during the quarter, in May 2025 we achieved first sales and the Company expects to report revenue from the Longanesi field as a part of second quarter results.

For the first quarter 2025, AleAnna reported net loss of $2.0 million. This amounts to a basic and diluted net loss per common share of ($0.05), compared with ($3.41) net loss per common share recorded by the Company in the first quarter 2024.

As of March 31, 2025, AleAnna had cash and cash equivalents of $27.8 million, providing the necessary liquidity to support development activities and pursue strategic opportunities.

Management Commentary

Marco Brun, Chief Executive Officer, remarked on AleAnna’s recent accomplishments: “We continue to execute on our business strategy and are encouraged by the initial performance at the Longanesi field. Although first quarter results did not include revenue from Longanesi, with the onset of sales in early May 2025 we expect to report revenue in our second quarter results. With a healthy balance sheet and growing operational momentum, we’re focused on delivering long-term value to our shareholders.”
