The realized natural gas price for Q1 2024 was 2.8 $/MMBtu, a 40% decrease y-o-y, mainly driven by a 61% decrease in industrial gas prices.

Total revenues in Q1 2024 were 317.4 $MM, stable y-o-y, mainly driven by higher oil realized prices and partially offset by changes to oil inventory. During Q1 2024, net revenues from oil and gas exports were 126.1 $MM and represented 41% of total net revenues, which were 307.8 $MM. Net oil export revenues in Q1 2024 were 119.1 $MM and represented 41% of net oil revenues.

Lifting cost in Q1 2024 was 4.3 $/boe, a 33% decrease compared to Q1 2023, reflecting the consolidation of our new operating model, fully focused on our shale oil assets, following the Transferred Conventional Assets (as defined below) as of March 1, 2023 (1).

Adjusted EBITDA for Q1 2024 was 220.6 $MM, an 8% increase y-o-y, mainly driven by lower lifting costs and stable revenues. Adjusted EBITDA margin was 68%, 4 p.p. above Q1 2023.

Adjusted Net Income during Q1 2024 totaled 47.4 $MM, compared to 72.0 $MM during Q1 2023, mainly driven by higher Current income tax expense and Depreciation, depletion and amortization, and partially offset by a higher Adjusted EBITDA.

Rounding amounts and percentages: Certain amounts and percentages included in this presentation have been rounded for ease of presentation.

For this reason, certain percentage amounts in this presentation may vary from those obtained by performing the same calculations using the figures in the financial statements. In addition, certain other amounts that appear in this presentation may not sum due to rounding.

This presentation contains certain metrics that do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies. Such metrics have been included herein to provide readers with additional measures to evaluate the Company's performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods.

We may or may not refer back to these projections in our future periodic reports filed under the Exchange Act. These expectations and projections are subject to significant known and unknown risks and uncertainties which may cause our actual results, performance or achievements, or industry results, to be materially different from any expected or projected results, performance or achievements expressed or implied by such forward-looking statements.
