Vista Energy, S.A.B. de C.V. ("Vista" or the "Company") (NYSE: VIST in the New York Stock Exchange; BMV: VISTA in the Mexican Stock Exchange), reported today financial and operational results for full year 2022 and Q4 2022.

Full year 2022 highlights:

During 2022, the Company completed and tied-in 28 shale oil wells. Five pads were tied-in in Bajada del Palo Oeste (BPO-11 to BPO-15), which added 20 new wells on production, increasing the total number of wells on production in the block to 60 at year-end. In Bajada del Palo Este, the Company completed and tied-in its first two wells. In Aguada Federal, the Company completed and tied-in its first six wells. Total shale production in 2022 averaged 34,671 boe/d.

Total proved reserves as of December 31, 2022, totaled 251.6 MMboe, a 39% increase compared to 181.6 MMboe as of December 31, 2021. The increase was mainly driven by increased drilling and completion activity and strong well performance in Bajada del Palo Oeste and Aguada Federal. The implied reserves replacement ratio was 495%, while the oil reserves replacement ratio was 515%.

During 2022, total production was 48,560 boe/d, composed of 40,078 bbl/d of oil, representing 83% of the total production, 1.28 MMm3/d of natural gas, representing 16% of the total production, and 450 boe/d of NGL, representing the remaining 1%. Total production in 2022 increased 25% vis-à-vis 2021. Vista exported 6,567.4 Mbbl of oil (represented 44% of oil sales volumes), a 115% increase y-o-y.

Bajada del Palo Oeste

The certified P1 oil and gas reserves in Bajada del Palo Oeste were 186.4 MMboe as of December 31, 2022, a 20% increase with respect to year-end 2021.

The increase was mainly driven by new well activity and strong results in well productivity, as the Company tied-in 20 new wells during 2022. This led to the addition of 32 P1 shale oil well locations in Bajada del Palo Oeste, resulting in a total of 166 booked P1 locations. Proved additions in the block totaled 42.9 MMboe.

The Company has identified up to 550 new well locations in the block and has drilled and tied-in 60 shale oil wells since the start of the project in 2018.

Aguada Federal

The certified P1 oil and gas reserves in Aguada Federal were 37.4 MMboe as of December 31, 2022. The block had no certified P1 reserves at the end of 2021.

The increase was mainly driven by new well activity, as the Company tied-in six new wells during 2022, which led to the addition of 40 P1 shale oil well locations in Aguada Federal.

Vista acquired a 50% working interest in the block in September 2021, and the remaining operated 50% working interest in January 2022. The Company has identified up to 150 new well locations in the block.

Mexico

Certified P1 reserves in block CS-01, located in Tabasco, Mexico, were 4.0 MMboe as of December 31, 2022, down from 4.5 MMboe at year-end 2021. The change was driven by 0.2 MMboe of 2022 production and a negative revision of 0.3 MMboe.

P1 reserves valuation

In accordance with the regulations set forth by the United States Securities and Exchange Commission ("SEC"), future net cash flows were calculated by applying current prices of oil and gas reserves (with consideration of price changes only to the extent provided by contractual arrangements) to estimated future production of proved oil and gas reserves as of the date reported, less the estimated future expenditures (based on current costs) to be incurred in developing and producing the proved reserves. Future net cash flows were then discounted using a factor of 10% per annum.

For the assets located in Argentina, the proved reserves as of December 31, 2022, were calculated with a price of 72.3$/bbl for oil, 31.2 $/boe for LPG and 3.9 $/MMBtu for natural gas, compared to 54.9 $/bbl, 26.7 $/boe and 3.4 $/MMBtu, respectively, as of December 31, 2021. These prices are assumed flat for the entire valuation in accordance with SEC regulations.

The estimated certified future net cash flows attributable to Vista's interests in the P1 reserves, as of December 31, 2022, of the properties located in Argentina, evaluated using the regulations established by the SEC, are summarized as follows:

Adjusted Net Income in Q4 2022 was 171.0 $MM, compared to an Adjusted Net Income of 35.4 $MM in Q4 2021. The y-o-y change was primarily driven by (a) higher Adjusted EBITDA (201.7 $MM in Q4 2022 compared to 116.5 $MM in Q4 2021), (b) a Current income tax benefit of 54.6 $MM in Q4 2022 compared to an expense of 15.2 $MM in Q4 2021 (1), (c) no Restructuring and reorganization expenses in Q4 2022 compared to 1.6 $MM in Q4 2021, offset by (d) higher Depreciation, depletion and amortization for 63.1 $MM in Q4 2022 compared to 46.9 $MM in Q4 2021, and (e) Financial results (net of changes in the fair value of warrants) for a total loss of 22.1 $MM in Q4 2022, compared to a loss 17.4 $MM in Q4 2021 (2).

In October 2022, the meeting of holders of the Warrants issued by the Company approved the amendments to the warrant indenture and the global certificate that covers such Warrants, by means of which a cashless exercise mechanism for Vista Warrants was implemented, entitling warrant holders to, in their sole discretion or at Vista's discretion, obtain one Series A share representative of the capital stock of the Company for each 31 Warrants owned. As a result, a maximum of 3,215,483 shares will become outstanding once all Warrants are converted. As of October 4, 2022, the liability for warrants was settled for 32.9 $MM, an amount equal to the 3,215,483 series "A" shares.

This presentation does not contain all the Company's financial information. As a result, investors should read this presentation in conjunction with the Company's consolidated financial statements and other financial information available on the Company's website. All the amounts contained herein are unaudited.

Rounding amounts and percentages: Certain amounts and percentages included in this presentation have been rounded for ease of presentation. Percentage figures included in this presentation have not in all cases been calculated on the basis of such rounded figures, but on the basis of such amounts prior to rounding. 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.

No reliance may be placed for any purpose whatsoever on the information contained in this document or on its completeness. Certain information contained in this document has been obtained from published sources, which may not have been independently verified or audited. No representation or warranty, express or implied, is given or will be given by or on behalf of the Company, or any of its affiliates (within the meaning of Rule 405 under the Act, "Affiliates"), members, directors, officers or employees or any other person (the "Related Parties") as to the accuracy, completeness or fairness of the information or opinions contained in this presentation or any other material discussed verbally, and any reliance you place on them will be at your sole risk. Any opinions presented herein are based on general information gathered at the time of writing and are subject to change without notice.

The information and opinions contained in this presentation are provided as at the date of this presentation and are subject to verification, completion and change without notice.

This presentation includes "forward-looking statements" concerning the future. The words such as "believes," "thinks," "forecasts," "expects," "anticipates," "intends," "should," "seeks," "estimates," "future" or similar expressions are included with the intention of identifying statements about the future. For the avoidance of doubt, any projection, guidance or similar estimation about the future or future results, performance or achievements is a forward-looking statement. Although the assumptions and estimates on which forward-looking statements are based are believed by our management to be reasonable and based on the best currently available information, such forward-looking statements are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond our control.

There will be differences between actual and projected results, and actual results may be materially greater or materially less than those contained in the projections. Projections related to production results as well as costs estimations are based on information as of the date of this presentation and reflect numerous assumptions including assumptions with respect to type curves for new well designs and certain frac spacing expectations, all of which are difficult to predict and many of which are beyond our control and remain subject to several risks and uncertainties. The inclusion of the projected financial information in this document should not be regarded as an indication that we or our management considered or consider the projections to be a reliable prediction of future events. As such, no representation can be made as to the attainability of projections, guidances or other estimations of future results, performance or achievements. We have not warranted the accuracy, reliability, appropriateness or completeness of the projections to anyone. Neither our management nor any of our representatives has made or makes any representation to any person regarding our future performance compared to the information contained in the projections, and none of them intends to or undertakes any obligation to update or otherwise revise the projections to reflect circumstances existing after the date when made or to reflect the occurrence of future events in the event that any or all of the assumptions underlying the projections are shown to be in error. 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. Many important factors could cause our actual results, performance or achievements to differ materially from those expressed or implied in our forward-looking statements, including, among other things: uncertainties relating to future government concessions and exploration permits; adverse outcomes in litigation that may arise in the future; general political, economic, social, demographic and business conditions in Argentina, Mexico and in other countries in which we operate; changes in law, rules, regulations and interpretations and enforcements thereto applicable to the Argentine and

Forward-looking statements speak only as of the date on which they were made, and we undertake no obligation to release publicly any updates or revisions to any forward-looking statements contained herein because of new information, future events or other factors. In light of these limitations, undue reliance should not be placed on forward-looking statements contained in this presentation.
