#### NEW VISTA ACQUISITION CORP

#### 125 South Wacker Drive, Suite 300<br>Chicago, IL 60606

#### PROXY STATEMENT FOR EXTRAORDINARY GENERAL MEETING<br>OF<br>NEW VISTA ACQUISITION CORP
Dear Shareholders of New Vista Acquisition Corp:

You are cordially invited to attend the Extraordinary General Meeting (the "*Extraordinary General Meeting*") of New Vista Acquisition Corp, a Cayman Islands exempted company (the "*Company*," "*New Vista*," "*we*," "*us*" or "*our*"), to be held on February 10, 2023, at 10:00 a.m., New York City time, at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, located at One Manhattan West, New York, NY 10001 (the "Extraordinary General Meeting"), or at such other time, on such other date and at such other place to which the meeting may be postponed or adjourned, or to attend virtually via the Internet. You will be able to attend the Extraordinary General Meeting online, vote, view the list of shareholders entitled to vote at the Extraordinary General Meeting and submit your questions during the Extraordinary General Meeting by visiting *www.cstproxy.com/newvistacap/2023*. While shareholders are encouraged to attend the meeting virtually, you will be permitted to attend the Extraordinary General Meeting in person at the offices of Skadden, Arps, Slate, Meagher & Flom LLP only if you (i) are fully vaccinated against COVID-19 and show proof of such vaccination, (ii) complete a visitor health form upon arrival and (iii) reserve your attendance at least two business days in advance of the Extraordinary General Meeting by contacting Skadden, Arps, Slate, Meagher & Flom LLP, at One Manhattan West, New York, NY 10001, telephone (212) 735-3000. The accompanying proxy statement is dated January 12, 2023 and is first being mailed to shareholders of the Company on or about January 12, 2023.

Please promptly submit your proxy vote by completing, dating, signing and returning the enclosed proxy, so that your shares will be represented at the Extraordinary General Meeting. It is strongly recommended that you complete and return your proxy card before the Extraordinary General Meeting date to ensure that your shares will be represented at the Extraordinary General Meeting. Instructions on how to vote your shares are on the proxy materials you received for the Extraordinary General Meeting.

The Extraordinary General Meeting is being held to consider and vote upon the following proposals:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Proposal No. 1 — The Extension Proposal** — as a special resolution, to amend the Company's Amended and Restated Memorandum and Articles of Association (the "*Charter*") pursuant to an amendment to the Charter in the form set forth in <u>Annex A</u> of the accompanying proxy statement to extend the date by which the Company must either (i) consummate a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination, which we refer to as our initial Business Combination or (ii) cease its operations except for the purpose of winding up if it fails to complete such initial Business Combination and (iii) redeem all of the New Vista Class A Shares, par value $0.0001 per share, of the Company ("*New Vista Class A Shares*"), included as part of the units sold in the Company's initial public offering that was consummated on February 19, 2021 (the "*IPO*"), from February 19, 2023, to February 19, 2024 (the "*Extension*," such period, the "*Extension Period*" and such end date, the "*Extended Date*");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Proposal No. 2 — The Redemption Limitation Amendment Proposal —** as a special resolution, to amend the Company's Charter pursuant to an amendment to the Charter as set forth in <u>Annex A</u> of the accompanying proxy statement to eliminate from the Charter the limitation that the Company may not redeem public shares to the extent that such redemption would result in the Company having net tangible assets of less than $5,000,001 (the "*Redemption Limitation*") in order to allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation (the "*Redemption Limitation Amendment*" and such proposal, the "*Redemption Limitation Amendment Proposal*");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Proposal No. 3 — The Liquidation Amendment Proposal —** a proposal to amend the Charter as set forth in <u>Annex A</u> of the accompanying proxy statement to permit our Board, in its sole discretion, to elect to wind up our operations on an earlier date (the "*Liquidation Amendment*" and such proposal, the "*Liquidation Amendment Proposal*" and, collectively with the Extension Proposal and the Redemption Limitation Amendment Proposal, the "*Charter Amendment Proposals*");

------

[**Table of Contents**](#TOC001)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) **Proposal No. 4 — The Trust Amendment Proposal —** a proposal to amend the Company's investment management trust agreement, dated as of February 16, 2022, by and between Continental Stock Transfer & Trust Company ("*Continental*") and the Company (the "*Trust Agreement*") pursuant to an amendment to the Trust Agreement in the form set forth in <u>Annex B</u> of the accompanying proxy statement to extend the date by which the Company would be required to consummate our initial Business Combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion (the "*Trust Amendment*" and such proposal, the "*Trust Amendment Proposal*"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) **Proposal No. 5 — The Adjournment Proposal —** as an ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of any of the Charter Amendment Proposals (the "*Adjournment Proposal*"), which will only be presented at the Extraordinary General Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Extraordinary General Meeting to approve any of the Charter Amendment Proposals.

**<u>Each of the proposals is more fully described in the accompanying proxy statement, which you are encouraged to read carefully.</u>**

The purpose of the Extension Proposal is to allow the Company more time to complete an initial Business Combination. The Charter provides that the Company has until February 19, 2023 to complete an initial Business Combination. While the Company is currently evaluating initial Business Combination opportunities, the board of directors of the Company (the "*Board*") has determined that there may not be sufficient time before February 19, 2023 to consummate an initial Business Combination. Therefore, the Board has determined that it is in the best interests of our shareholders to extend the date by which the Company must complete an initial Business Combination to the Extended Date.

The purpose of the Redemption Limitation Amendment Proposal is to eliminate from the Charter the Redemption Limitation in order to allow the Company to redeem public shares, irrespective of whether such redemption would exceed the Redemption Limitation. The Board believes it is in the best interests of the Company and its shareholders for the Company to be allowed to effect redemptions irrespective of the Redemption Limitation.

The purpose of the Liquidation Amendment Proposal is to amend our Charter to enable the Board, in its sole discretion, to liquidate the Trust Account and dissolve in accordance with law and to redeem all of the New Vista Class A Shares included as part of the units sold in the Company's IPO prior to the scheduled end of the Extension Period (including a date prior to the current termination date), after taking into account various factors, including, but not limited to, the prospect of identifying a target and negotiating and consummating a business combination prior to the end of the Extension Period.

The purpose of the Trust Amendment Proposal is to allow the Company to extend the date by which the Company would be required to consummate a business combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion. The Trust Amendment parallels the Charter Amendment Proposals.

In connection with the Charter Amendment Proposals, public shareholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account established in connection with the IPO (the "*Trust Account*"), including interest (net of taxes payable), *divided by* the number of then-issued and outstanding New Vista Class A Shares, regardless of how such public shareholders vote on the Charter Amendment Proposals or if they vote at all. If any of the Charter Amendment Proposals are approved by the requisite vote of shareholders and implemented, the remaining public shareholders will retain their right to redeem their New Vista Class A Shares upon consummation of our initial Business Combination if and when it is submitted to a vote of our shareholders, subject to any limitations set forth in the Charter, as amended. In addition, if the Extension Proposal is approved and implemented, the remaining public shareholders will be entitled to have their shares redeemed for cash if the Company has not completed an initial Business Combination by the Extended Date, subject to any limitations set forth in the Charter, as amended. Such limitations include that a public shareholder, together with any affiliate of such public shareholder or any other person with whom such public shareholder is acting in concert or as a group for purposes of acquiring, holding or disposing of New Vista Shares will be restricted from redeeming its New Vista Class A Shares with respect to more than 15% of the New Vista Class A Shares sold in the IPO. Accordingly, if a public shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the New Vista Class Shares sold in the IPO, then any such shares in excess of that 15% limit would not be redeemed for cash, without our prior consent.

[**Table of Contents**](#TOC001)

Based upon the amount held in the Trust Account as of September 30, 2022, which was $277,450,461, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $10.05 at the time of the Extraordinary General Meeting. The closing price of a New Vista Class A Share on January 11, 2023, was $10.12. The Company cannot assure shareholders that they will be able to sell their New Vista Class A Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

Pursuant to the Charter, a public shareholder may request that the Company redeem all or a portion of such public shareholder's public shares for cash if any of the Charter Amendment Proposals are approved by the requisite vote of shareholders and implemented. You will be entitled to receive cash for any public shares to be redeemed only if you:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) (i) hold public shares or (ii) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares and (iii) such redemption would not result in the Company having net tangible assets of less than $5,000,001 (unless the Redemption Limitation Amendment Proposal is approved and implemented); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) prior to 5:00 p.m., New York City time, on February 8, 2023 (two (2) business days prior to the vote at the Extraordinary General Meeting), (i) submit a written request to Continental, the Company's transfer agent, that the Company redeem your public shares for cash and (ii) tender or deliver your shares (and share certificates (if any) and other redemption forms) to the transfer agent, physically or electronically through The Depository Trust Company.

Any demand for redemption, once submitted to the Company, may not be withdrawn unless the directors of the Company determine (in their sole discretion) to permit the withdrawal of such redemption request (which they may do in whole or in part). If you tendered or delivered your shares for redemption to Continental and decide within the required timeframe not to exercise your redemption rights, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the phone number or address listed under the question "Who can help answer my questions?" below.

Additionally, we will not redeem shares if (i) none of the Charter Amendment Proposals are approved, (ii) none of the Charter Amendment Proposals are implemented (even if approved), or (iii) the Redemption Limitation Amendment Proposal is not approved or not implemented and redemptions would cause the Redemption Limitation to be exceeded. In any of these scenarios, you will not receive cash for public shares. In the event that the Redemption Limitation Amendment Proposal is not approved or not implemented and we receive notice of redemptions of public shares approaching or in excess of the Redemption Limitation, we and/or the Company's sponsor, New Vista Acquisition Sponsor LLC, a Delaware limited liability company (the "*Sponsor*"), may take action to increase our net tangible assets to avoid the Redemption Limitation, which may include, at our and our Sponsor's option and in our and its sole discretion, any, several or all of the following actions: (a) attempting to secure waivers of certain of our significant liabilities, including the deferred underwriting fees and (b) entering into non-redemption agreements with certain of our significant shareholders. If the Redemption Limitation Amendment Proposal is not approved or not implemented and the Redemption Limitation is exceeded, either because we do not take action to increase our net tangible assets or because our attempt to do so is not successful, then we will not proceed with the amendments set forth in <u>Annex A</u> of the accompanying proxy statement and we will not redeem any public shares. In such case, public shares which a public shareholder elects to redeem but which are not redeemed shall be returned to such public shareholder or such public shareholder's account and such public shareholder will retain the right to have their public shares redeemed for cash if the Company has not completed an initial Business Combination by February 19, 2023.

Holders of units of the Company must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank, as applicable, that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, their own name, the holder must contact Continental directly and instruct it to do so. Your broker, bank or other nominee may have an earlier deadline by which you must provide instructions to separate the units into the underlying public shares and public warrants in order to exercise redemption rights with respect to the public shares, so you should contact your broker, bank or other nominee or intermediary. **<u>Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Charter Amendment Proposals.</u>**

[**Table of Contents**](#TOC001)

If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Class A Shares and New Vista Class B ordinary shares, par value $0.0001 per share, of the Company (the "*New Vista Class B Shares*" and together with the New Vista Class A Shares, the "*New Vista Shares*") issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

Approval of the Redemption Limitation Amendment Proposal also requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

Approval of the Liquidation Amendment Proposal also requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

Approval of the Trust Amendment Proposal requires the affirmative vote of 65% of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a simple majority of the holders of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

If the Charter Amendment Proposals are approved, the Company will file an amendment to the Charter with the Cayman Islands Registrar of Companies (the "*Cayman Registrar*") in the form of <u>Annex A</u> hereto to extend the time it has to complete an initial Business Combination until the Extended Date, to remove the Redemption Limitation and to permit the Board to elect to wind up its operations on an earlier date. The Company will then continue to work to consummate an initial Business Combination by the Extended Date.

If the Extension Proposal, the Redemption Limitation Amendment Proposal, the Liquidation Amendment Proposal and the Trust Amendment Proposal are approved and the Extension is implemented, then in accordance with the Company's Trust Agreement, the Trust Account will not be liquidated (other than to effectuate the redemptions described above) until the earlier of (a) receipt by the trustee of a termination letter (in accordance with the terms of the Trust Agreement) or (b) the expiration of the Extension Period.

Notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the amendment to the Company's Charter with the Cayman Registrar. Assuming the Extension Proposal is approved, if our Board abandons the Redemption Limitation Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

**<u>THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE EXTENSION PROPOSAL, THE REDEMPTION LIMITATION AMENDMENT PROPOSAL, THE LIQUIDATION AMENDMENT PROPOSAL, THE TRUST AMENDMENT PROPOSAL AND, IF PRESENTED, THE ADJOURNMENT PROPOSAL.</u>**

The Board has fixed the close of business on January 10, 2023, as the record date for the Extraordinary General Meeting (the "*Record Date*"). Only shareholders of record on the Record Date are entitled to notice of and to vote at the Extraordinary General Meeting or any postponement or adjournment thereof. Further information regarding voting rights and the matters to be voted upon is presented in the accompanying proxy statement.

**<u>You are not being asked to vote on an initial Business Combination at this time. If any of the Charter Amendment Proposals are approved and implemented and you do not elect to redeem your public shares in connection with the Charter Amendment Proposals, you will retain the right to vote on an initial Business Combination if and when such transaction is submitted to shareholders and the right to redeem your public shares for cash from the Trust Account in the event a proposed initial Business Combination is approved and completed or the Company has not consummated an initial Business Combination by the Extended Date. If an initial Business Combination is not consummated by the Extended Date, assuming the Extension is implemented, the Company will redeem its public shares.</u>**

All of our shareholders are cordially invited to attend the Extraordinary General Meeting via the Internet at *www.cstproxy.com/newvistacap/2023*. To ensure your representation at the Extraordinary General Meeting, you are urged to complete, sign, date and return your proxy card as soon as possible. If your shares are held in an account at a brokerage firm or bank, you must instruct your broker or bank on how to vote your shares. You may revoke your proxy card at any time prior to the Extraordinary General Meeting.

A shareholder's failure to vote in person or by proxy will not be counted towards the number of New Vista Shares required to validly establish a quorum. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals. We believe that each of the proposals is a "non-discretionary" matter, and therefore, there will not be any broker non-votes at the Extraordinary General Meeting.

YOUR VOTE IS IMPORTANT. Please sign, date and return your proxy card as soon as possible. You are requested to carefully read the proxy statement and accompanying Notice of the Extraordinary General for a more complete statement of matters to be considered at the Extraordinary General Meeting.

If you have any questions or need assistance voting your ordinary shares, please contact Morrow Sodali LLC ("*Morrow*"), our proxy solicitor, by calling (800) 662-5200, or banks and brokers can call collect at (203) 658-9400.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) **Proposal No. 5 — The Adjournment Proposal —** as an ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of any of the Charter Amendment Proposals (the "*Adjournment Proposal*"), which will only be presented at the Extraordinary General Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Extraordinary General Meeting to approve any of the Charter Amendment Proposals.

The above matters are more fully described in the accompanying proxy statement. **<u>We urge you to read carefully the accompanying proxy statement in its entirety.</u>**

Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting.

Approval of the Redemption Limitation Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting.

Approval of the Liquidation Amendment Proposal also requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

Approval of the Trust Amendment Proposal requires the affirmative vote of 65% of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a simple majority of the holders of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who vote at the Extraordinary General Meeting.

Notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the filing with the Cayman Registrar. Assuming the Extension Proposal is approved, if our Board abandons the Redemption Limitation Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

In connection with the Charter Amendment Proposals, public shareholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account established in connection with the IPO (the "*Trust Account*"), including interest (net of taxes payable), *divided by* the number of then issued and outstanding New Vista Class A Shares, regardless of how such public shareholders vote on the Charter Amendment Proposals or if they vote at all. If any of the Charter Amendment Proposals are approved by the requisite vote of shareholders and implemented, the remaining public shareholders will retain their right to redeem their New Vista Class A Shares upon consummation of our initial Business Combination if and when it is submitted to a vote of our shareholders, subject to any limitations set forth in the Charter, as amended. In addition, if the Extension Proposal is approved and implemented, the remaining public shareholders will be entitled to have their shares redeemed for cash if the Company has not completed an initial Business Combination by the Extended Date, subject to any limitations set forth in the Charter, as Amended. Such limitations include that a public shareholder, together with any affiliate of such public shareholder or any other person with whom such public shareholder is acting in concert or as a group for purposes of acquiring, holding or disposing of New Vista Shares will be restricted from redeeming its New Vista Class A Shares with respect to more than 15% of the New Vista Class A Shares sold in the IPO. Accordingly, if a public shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the New Vista Class Shares sold in the IPO, then any such shares in excess of that 15% limit would not be redeemed for cash, without our prior consent.

[**Table of Contents**](#TOC001)

Pursuant to the Charter, a public shareholder may request that the Company redeem all or a portion of such public shareholder's public shares for cash if any of the Charter Amendment Proposals are approved by the requisite vote of shareholders and implemented. You will be entitled to receive cash for any public shares to be redeemed only if you:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) (i) hold public shares or (ii) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares and (iii) such redemption would not result in the Company having net tangible assets of less than $5,000,001 (unless the Redemption Limitation Amendment Proposal is approved and implemented); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) prior to 5:00 p.m., New York City time, on February 8, 2023 (two (2) business days prior to the vote at the Extraordinary General Meeting), (i) submit a written request to Continental, the Company's transfer agent, that the Company redeem your public shares for cash and (ii) tender or deliver your shares (and share certificates (if any) and other redemption forms) to the transfer agent, physically or electronically through The Depository Trust Company.

Any demand for redemption, once submitted to the Company, may not be withdrawn unless the directors of the Company determine (in their sole discretion) to permit the withdrawal of such redemption request (which they may do in whole or in part). If you tendered or delivered your shares for redemption to Continental and decide within the required timeframe not to exercise your redemption rights, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the phone number or address listed under the question "*Who can help answer my questions*?" below.

Additionally, we will not redeem shares if (i) none of the Carter Amendment Proposals are approved, (ii) none of the Charter Amendment Proposals are implemented (even if approved), or (iii) the Redemption Limitation Amendment Proposal is not approved or not implemented and redemptions would cause the Redemption Limitation to be exceeded. In any of these scenarios, you will not receive cash for public shares. In the event that the Redemption Limitation Amendment Proposal is not approved or not implemented and we receive notice of redemptions of public shares approaching or in excess of the Redemption Limitation, we and/or the Company's sponsor, New Vista Acquisition Sponsor LLC, a Delaware limited liability company, may take action to increase our net tangible assets to avoid the Redemption Limitation, which may include, at our and our Sponsor's option and in our and its sole discretion, any, several or all of the following actions: (a) attempting to secure waivers of certain of our significant liabilities, including the deferred underwriting fees and (b) entering into non-redemption agreements with certain of our significant shareholders. If the Redemption Limitation Amendment Proposal is not approved or not implemented and the Redemption Limitation is exceeded, either because we do not take action to increase our net tangible assets or because our attempt to do so is not successful, then we will not proceed with the amendments set forth in <u>Annex A</u> of the accompanying proxy statement and we will not redeem any public shares. In such case, public shares which a public shareholder elects to redeem but which are not redeemed shall be returned to such public shareholder or such public shareholder's account and such public shareholder will retain the right to have their public shares redeemed for cash if the Company has not completed an initial Business Combination by February 19, 2023.

Holders of units of the Company must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank, as applicable, that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, their own name, the holder must contact Continental directly and instruct it to do so. Your broker, bank or other nominee may have an earlier deadline by which you must provide instructions to separate the units into the underlying public shares and public warrants in order to exercise redemption rights with respect to the public shares, so you should contact your broker, bank or other nominee or intermediary. **<u>Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Charter Amendment Proposals.</u>**

If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public

[**Table of Contents**](#TOC001)

shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

The Company's sponsor is New Vista Sponsor LLC, a Delaware limited liability company (the "*Sponsor*"). The Sponsor and the Company's directors and officers have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any New Vista Class B Shares held by it or them, as applicable, if the Company fails to complete an initial Business Combination by February 19, 2023, although they will be entitled to liquidating distributions from the Trust Account with respect to any New Vista Class A Shares they hold if the Company fails to complete its initial Business Combination by such date. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

The Sponsor has agreed that it will be liable to Company if, and to the extent, any claims by a third party (other than New Vista's independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (a) $10.00 per public share or (b) such lesser amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the assets in the Trust Account, in each case net of the amount of interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company's indemnity of the underwriters for the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that an executed waiver is deemed to be unenforceable against a third party, then the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company has not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believes that the Sponsor's only assets are securities of the Company and, therefore, the Sponsor may not be able to satisfy those obligations. None of the Company's officers or directors will indemnify the Company for claims by third parties, including, without limitation, claims by vendors and prospective target businesses.

Based upon the amount held in the Trust Account as of September 30, 2022, which was $277,450,461, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $10.05 at the time of the Extraordinary General Meeting. The closing price of a New Vista Class A Share on January 11, 2023, was $10.12. The Company cannot assure shareholders that they will be able to sell their New Vista Class A Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

If any of the Charter Amendment Proposals are approved, such approval will constitute consent for the Company to (i) remove from the Trust Account an amount (the "*Withdrawal Amount*") equal to the number of public shares properly redeemed *multiplied* by the aggregate amount then on deposit in the Trust Account, including interest (net of taxes payable), *divided* by the number of then issued and outstanding public shares and (ii) deliver to the holders of such redeemed public shares their portion of the Withdrawal Amount. The funds remaining in the Trust Account after the removal of such Withdrawal Amount shall be available for use by the Company to complete an initial Business Combination on or before the Extended Date. Holders of public shares who do not redeem their public shares now will retain their redemption rights and their ability to vote on an initial Business Combination through the Extended Date if the Extension Proposal is approved. If the Redemption Limitation Amendment Proposal is not approved or not implemented and there are significant requests for redemption such that the Company's net tangible assets would be less than $5,000,001 upon the consummation of an initial Business Combination, the Charter would prevent the Company from being able to redeem its public shares.

The withdrawal of the Withdrawal Amount will reduce the amount held in the Trust Account, and the amount remaining in the Trust Account may be significantly less than the approximately $277,450,461 that was in the Trust Account as of September 30, 2022. In such event, the Company may need to obtain additional funds to complete its initial Business Combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

#### CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This proxy statement contains "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the "*Exchange Act*"), and the Private Securities Litigation Reform Act of 1995, as amended. Forward-looking statements may relate to the Company's initial Business Combination and any other statements relating to future results, strategy and plans of the Company (including statements which may be identified by the use of the words "plans," "expects" or "does not expect," "estimated," "is expected," "budget," "scheduled," "estimates," "forecasts," "intends," "anticipates" or "does not anticipate," "targets," "projects," "contemplates," "predicts," "potential," "continue," or "believes," or variations of such words and phrases or state that certain actions, events or results "may," "could," "would," "should," "might," "will" or "will be taken," "occur" or "be achieved").

Forward-looking statements are based on the opinions and estimates of management of the Company as of the date such statements are made, and they are subject to known and unknown risks, uncertainties, assumptions and other factors that may cause the actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount of redemptions by our public shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our being a company with no operating history and no operating revenues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to select an appropriate target business or businesses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to complete our initial Business Combination (as defined above);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our expectations around the performance of a prospective target business or businesses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• disrupted global supply chains and significant volatility and disruption of financial markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our officers and directors allocating their time to other businesses and potentially having conflicts of interest with our business or in approving our initial Business Combination, as a result of which they would then receive expense reimbursements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the potential incentive to consummate an initial Business Combination with an acquisition target that subsequently declines in value or is unprofitable for public investors due to the low initial price for the Founder Shares paid by our Sponsor and certain members of our team;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our potential ability to obtain additional financing, if needed, to complete our initial Business Combination;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our pool of prospective target businesses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to consummate an initial Business Combination due to the uncertainty resulting from the coronavirus ("COVID-19") pandemic and other events (such as terrorist attacks, natural disasters, global hostilities, or a significant outbreak of other infectious diseases);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the ability of our directors and officers to generate potential initial Business Combination opportunities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our public securities' potential liquidity and trading, including compliance with continued listing standards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the lack of a market for our securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the use of proceeds not held in the Trust Account (as defined above) or available to us from interest income on the Trust Account balance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Trust Account not being subject to claims of third parties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our financial performance;

#### QUESTIONS AND ANSWERS ABOUT THE EXTRAORDINARY GENERAL MEETING
These Questions and Answers are only summaries of the matters they discuss. They do not contain all of the information that may be important to you. You should read carefully the entire document, including any annexes to this proxy statement.

#### Why am I receiving this proxy statement?
This proxy statement and the enclosed proxy card are being sent to you in connection with the solicitation of proxies by our Board for use at the Extraordinary General Meeting to be held virtually and in person or by proxy on February 10, 2023, or at any adjournments or postponements thereof. This proxy statement summarizes the information that you need to make an informed decision on the proposals to be considered at the Extraordinary General Meeting.

New Vista is a blank check company incorporated on December 21, 2020, as a Cayman Islands exempted company and incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses, which we refer to as our initial Business Combination. On February 19, 2021, New Vista consummated its IPO of its units, with each unit consisting of one (1) New Vista Class A Share and one-third of one redeemable warrant to purchase one (1) New Vista Class A Share, which included the full exercise by the underwriters of their over-allotment option in the amount of 3,600,000 units. Simultaneously with the closing of the IPO, New Vista completed the private sale of 5,680,000 private placement warrants at a purchase price of $1.50 per private placement warrant to the Sponsor, generating gross proceeds to us of $8,520,000. Following the closing of New Vista's IPO, a total of $276,000,000 ($10.00 per unit) of the net proceeds from the IPO and the sale of the private placement warrants was placed in the Trust Account, with Continental acting as trustee. Our Charter provides for the return of the IPO proceeds held in the Trust Account to the holders of public shares if we do not complete our initial Business Combination by February 19, 2023.

The purpose of the Extension Proposal is to allow the Company more time to complete an initial Business Combination. While the Company is currently evaluating initial Business Combination opportunities, the Board has determined that there may not be sufficient time before February 19, 2023 to consummate an initial Business Combination. Therefore, the Board has determined that it is in the best interests of our shareholders to extend the date by which the Company must complete an initial Business Combination to the Extended Date.

The purpose of the Redemption Limitation Amendment Proposal is to eliminate from the Charter the limitation that the Company may not redeem public shares to the extent that such redemption would result in the Company having net tangible assets of less than $5,000,001 in order to allow the Company to redeem any public shares redeemed, irrespective of whether such redemption would exceed the Redemption Limitation.

The purpose of the Liquidation Amendment Proposal is to amend our Charter to enable the Board, in its sole discretion, to liquidate the Trust Account and dissolve in accordance with law and to redeem all of the New Vista Class A Shares included as part of the units sold in the Company's IPO prior to the current termination date), after taking into account various factors, including, but not limited to, the prospect of identifying a target and negotiating and consummating a business combination prior to the end of the Extension Period.

The purpose of the Trust Amendment Proposal is to allow the Company to extend the date by which the Company would be required to consummate a business combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion. The Trust Amendment parallels the Charter Amendment Proposals.

#### What is being voted on?
You are being asked to vote on the following proposals:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Proposal No. 1 — The Extension Proposal** — as a special resolution, to amend the Company's Charter pursuant to an amendment to the Charter in the form set forth in <u>Annex A</u> of the accompanying proxy statement to extend the date by which the Company must either (i) consummate a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination, which we refer to as our

[**Table of Contents**](#TOC001)

initial Business Combination, or (ii) cease its operations except for the purpose of winding up if it fails to complete such initial Business Combination and (iii) redeem all of the Class A ordinary shares, par value $0.0001 per share, of the Company, from February 19, 2023, to the Extended Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Proposal No. 2 — The Redemption Limitation Amendment Proposal —** as a special resolution, to amend the Company's Charter pursuant to an amendment to the Charter in the form set forth in <u>Annex A</u> of the accompanying proxy statement to eliminate from the Charter the limitation that the Company may not redeem public shares to the extent that such redemption would result in the Company having net tangible assets of less than $5,000,001 in order to allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Proposal No. 3 — The Liquidation Amendment Proposal** — a proposal to amend the Charter as set forth in Annex A of the accompanying proxy statement to permit our Board, in its sole discretion, to elect to wind up our operations on an earlier date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) **Proposal No. 4 — The Trust Amendment Proposal** — a proposal to amend the Trust Agreement, pursuant to an amendment to the Trust Agreement in the form set forth in Annex B of the accompanying proxy statement to extend the date by which the Company would be required to consummate our initial Business Combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) **Proposal No. 5 — The Adjournment Proposal** — as an ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of any of the Charter Amendment Proposals, which will only be presented at the Extraordinary General Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Extraordinary General Meeting to approve any of the Charter Amendment Proposals.

If the Extension Proposal is approved, we plan to hold another extraordinary general meeting prior to the Extended Date in order to seek shareholder approval of an initial Business Combination and related proposals.

**You are not being asked to vote on an initial Business Combination at this time. If any of the Charter Amendment Proposals are approved and implemented and you do not elect to redeem your public shares in connection with the Charter Amendment Proposals, you will retain the right to vote on an initial Business Combination if and when such transaction is submitted to shareholders and the right to redeem your public shares for cash from the Trust Account in the event a proposed initial Business Combination is approved and completed or the Company has not consummated an initial Business Combination by the Extended Date. If an initial Business Combination is not consummated by the Extended Date, assuming the Extension is implemented, the Company will redeem 100% of its public shares.**

In this regard, you must provide the broker, bank or other nominee with instructions on how to vote your shares.

#### Why should I vote to approve the Extension?
Our Board believes shareholders will benefit from the Company consummating an initial Business Combination and is proposing the Extension to extend the date by which the Company has to complete an initial Business Combination until the Extended Date. The Extension is expected to give the Company the opportunity to complete its initial Business Combination.

If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

We believe that the provisions of the Charter described in the preceding paragraph were included to protect the Company's shareholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable initial Business Combination in the timeframe contemplated by the Charter. We also believe, however, that given the Company's expenditure of time, effort and money on pursuing an initial Business Combination and our belief that the Business Combination is in the best interest of New Vista and our shareholders, the Extension is warranted.

The sole purpose of the Extension Proposal is to provide the Company with sufficient time to complete an initial Business Combination, which the Board believes is in the best interests of the Company and our shareholders. A copy of the proposed amendment to the Charter is attached to this proxy statement as <u>Annex A</u>.

Our Board recommends that you vote in favor of the Extension Proposal, but expresses no opinion as to whether you should redeem your public shares.

#### Why should I vote to approve the Redemption Limitation Amendment Proposal?
The purpose of the Redemption Limitation Amendment Proposal is to eliminate from the Charter the Redemption Limitation in order to allow the Company to redeem any public shares redeemed, irrespective of whether such redemption would exceed the Redemption Limitation.

Shareholders are entitled to exercise redemption rights in connection with the proposals to be voted on at the Extraordinary General Meeting. Under the Company's Charter, it cannot consummate an initial Business Combination unless it has net tangible assets of at least $5,000,001 upon consummation of an initial Business Combination. In addition, if holders of enough of the public shares were to seek redemption rights in connection with the consideration of these proposals, even if the amendments were approved by the requisite vote of shareholders, the Company would not be able to implement the amendments or provide redemption rights as its Charter requires that it must have at least $5,000,001 in net tangible assets to do so.

The Company believes that these limitations which may prevent it from completing an initial Business Combination are not needed. The purpose of such limitation was initially to ensure that the public shares not deemed to be a "penny stock" pursuant to Rule 3a51-1 under the Exchange Act in the event that such public shares failed to be listed on an approved national securities exchange. If the Redemption Limitation Amendment Proposal is not approved or not implemented and there are significant requests for redemption such that the Company's net tangible

[**Table of Contents**](#TOC001)

assets would be less than $5,000,001 upon the consummation of an initial Business Combination, the Charter would prevent the Company from being able to consummate an initial Business Combination even if all other conditions to closing are met.

We believe that the provisions of the Charter described in the preceding paragraph were included to protect the Company's shareholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable initial Business Combination in the timeframe contemplated by the Charter. We also believe, however, that given the Company's expenditure of time, effort and money on pursuing an initial Business Combination, and our belief that an initial Business Combination is in the best interest of the Company and our shareholders, the Extension is warranted.

In connection with the Charter Amendment Proposals, public shareholders may elect to redeem their shares of New Vista Class A Shares for a per-share price, payable in cash, equal to the aggregate amount as of two business days prior to the vote at the Extraordinary General Meeting in the Trust Account, including interest (net of taxes payable), *divided* by the number of then-issued and outstanding shares of New Vista Class A Shares, regardless of how such public shareholders vote on the Charter Amendment Proposals, or if they vote at all. If the Redemption Limitation Amendment Proposal is not approved or not implemented, we will not proceed with the Extension if redemptions of public shares cause us to have less than $5,000,001 of net tangible assets following approval of the Extension Proposal, as provided in the Charter.

Liquidation of the Trust Account is a fundamental obligation of the Company to the public shareholders and the Company is not proposing, and will not propose, to change that obligation to the public shareholders. If holders of public shares do not elect to redeem their public shares, such holders shall retain redemption rights in connection with an initial Business Combination. Assuming the Extension is approved, the Company will have until the Extended Date to complete its initial Business Combination.

Our Board recommends that you vote in favor of the Redemption Limitation Amendment Proposal, but expresses no opinion as to whether you should redeem your public shares.

#### Why should I vote to approve the Liquidation Amendment Proposal?
The purpose of the Liquidation Amendment Proposal is to amend our Charter to enable the Board, in its sole discretion, to liquidate the Trust Account and dissolve in accordance with law and to redeem all of the New Vista Class A Shares included as part of the units sold in the Company's IPO prior to the scheduled end of the Extension Period (including a date prior to the current termination date), after taking into account various factors, including, but not limited to, the prospect of identifying a target and negotiating and consummating a business combination prior to the end of the Extension Period. Accordingly, the Board believes that it is in the best interests of our shareholders to provide additional flexibility to wind up our operations, in which case we will liquidate the Trust Account and dissolve in accordance with law and to redeem all public shares. If a suitable business combination is timely identified, the Company intends to hold another shareholders' meeting prior to the expiration of the Extension Period in order to seek shareholder approval of a potential business combination.

Our Board believes that shareholders will benefit from enabling the Board to liquidate the Trust Account and dissolve in accordance with law and to redeem all public shares on a specified date following the effectiveness of the amended charter and prior to the scheduled end of the Extension Period (including a date prior to the current termination date), after taking into account various factors, including, but not limited to, the prospect of identifying a target and negotiating and consummating a business combination prior to the end of the Extension Period.

#### Why should I vote to approve the Trust Amendment Proposal?
The Company's current Trust Agreement provides that the Company has until 24 months after the closing of the IPO, and such later day as may be approved by the Company's shareholders in accordance with the Company's charter to terminate the Trust Agreement and liquidate the Trust Account.

The purpose of the Trust Amendment is to allow the Company to extend the date by which the Company would be required to consummate a business combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion. The Trust Amendment parallels the Charter Amendment Proposals.

[**Table of Contents**](#TOC001)

#### When would the Board abandon the Extension Proposal?
Our Board will abandon the Extension if our shareholders do not approve the Extension Proposal. Additionally, if the Extension is approved but the Redemption Limitation Amendment Proposal is not approved or not implemented, we are not permitted to redeem New Vista Class A Shares in an amount that would cause our net tangible assets to be less than $5,000,001, and we will not proceed with the Extension if redemptions of our shares of New Vista Class A Shares in connection with the Extension would cause us to have less than $5,000,001 of net tangible assets following approval of the Extension Proposal.

Additionally, notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the filing with the Cayman Registrar. Assuming the Extension Proposal is approved, if our Board abandons the Redemption Limitation Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

#### When would the Board abandon the Redemption Limitation Amendment Proposal?
Our Board will abandon the Redemption Limitation Amendment Proposal if our shareholders do not approve the Redemption Limitation Amendment Proposal or if our shareholders approve the Redemption Limitation Amendment Proposal but do not approve the Extension Proposal.

Additionally, notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the filing with the Cayman Registrar. Assuming the Extension Proposal is approved, if our Board abandons the Redemption Limitation Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

#### When would the Board abandon the Liquidation Amendment Proposal?
Our Board will abandon the Liquidation Amendment Proposal if our shareholders do not approve the Liquidation Amendment Proposal or if our shareholders approve the Liquidation Amendment Proposal but do not approve the Extension Proposal.

Additionally, notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the filing with the Cayman Registrar.

Additionally, notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the filing with the Cayman Registrar. Assuming the Extension Proposal is approved, if our Board abandons the Trust Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

[**Table of Contents**](#TOC001)

#### How do the Company insiders intend to vote their shares?
The Sponsor, the Company's directors, officers and initial shareholders and their permitted transferees (collectively, the "*Initial Shareholders*") collectively have the right to vote approximately 20% of the Company's issued and outstanding New Vista Shares, and are expected to vote all of their shares in favor of each proposal to be voted upon by our shareholders at the Extraordinary General Meeting.

The Sponsor and the Company's directors, officers and advisors, or any of their respective affiliates, may purchase public shares in privately negotiated transactions or in the open market prior to the Extraordinary General Meeting, although they are under no obligation to do so. Any such purchases that are completed after January 10, 2023 (the "*Record Date*") may include an agreement with a selling shareholder that such shareholder, for so long as it remains the record holder of the New Vista Shares in question, will vote in favor of the proposals and/or will not exercise its redemption rights with respect to the New Vista Shares so purchased. The purpose of such share purchases and other transactions would be to increase the likelihood that the proposals to be voted upon at the Extraordinary General Meeting are approved by the requisite number of votes. In the event that such purchases do occur, the purchasers may seek to purchase shares from shareholders who would otherwise have voted against the proposals and elected to redeem their shares for a portion of the Trust Account. Any such privately negotiated purchases may be effected at purchase prices that are below or in excess of the per-share pro rata portion of the Trust Account. Any public shares held by or subsequently purchased by our affiliates may be voted in favor of the proposals. None of the Sponsor or the Company's directors, officers or advisors or any of their respective affiliates may make any such purchases when they are in possession of any material nonpublic information not disclosed to the seller or during a restricted period under Regulation M under the Exchange Act.

#### Who is the Company's Sponsor?
The Company's sponsor is New Vista Acquisition Sponsor LLC, a Delaware limited liability company. The Sponsor currently owns 6,684,500 New Vista Class B Shares and is controlled by its managing members — Dennis A. Muilenburg, Kirsten Bartok Touw and Travis S. Nelson. Each of Mr. Muilenburg, Ms. Bartok Touw and Mr. Nelson are U.S. persons. Each of Mr. Muilenburg, Ms. Bartok Touw and Mr. Nelson may be deemed to beneficially own shares held by our Sponsor by virtue of their shared control over our Sponsor.

Subject to the other parties involved in our initial Business Combination, the Company does not believe that any of the above facts or relationships regarding the Sponsor would, by themselves, subject our initial Business Combination to regulatory review, including review by the Committee on Foreign Investment in the United States ("CFIUS"), nor does the Company believe that if such a review were conceivable that, based solely on such facts or relationships, such Business Combination ultimately would be prohibited.

However, if our initial Business Combination were to become subject to regulatory review and approval requirements, including pursuant to foreign investment regulations and review by governmental entities such as CFIUS, such Business Combination may be delayed or ultimately prohibited. For more information, see the section entitled "*Risk Factor — Our initial Business Combination may be delayed or ultimately prohibited if such initial Business Combination is subject to regulatory review and approval requirements, including pursuant to foreign investment regulations and review by governmental entities such as CFIUS*."

#### What vote is required to approve the Extension Proposal?
Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

#### What vote is required to approve the Redemption Limitation Amendment Proposal?
Approval of the Redemption Limitation Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

[**Table of Contents**](#TOC001)

#### What vote is required to approve the Liquidation Amendment Proposal?
Approval of the Liquidation Amendment Proposal also requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

#### What vote is required to approve the Trust Amendment Proposal?
Approval of the Trust Amendment Proposal requires the affirmative vote of 65% of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

#### What vote is required to approve the Adjournment Proposal?
Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a simple majority of the holders of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

#### What if I want to vote against or don't want to vote for any of the proposals?
If you do not want any of the proposals to be approved, you should vote against such proposals. A shareholder's failure to vote by proxy or to vote in person at the Extraordinary General Meeting will not be counted towards the number of shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on such proposals. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on either of the proposals. We believe that each of the proposals is a "non-discretionary" matter, and therefore, there will not be any broker non-votes at the Extraordinary General Meeting.

#### Will you seek any further extensions to liquidate the Trust Account?
Other than the Extension until the Extended Date, as described in this proxy statement, we do not anticipate seeking any further extension to consummate an initial Business Combination.

#### How are the funds in the Trust Account currently being held?
With respect to the regulation of special purpose acquisition companies like the Company ("*SPACs*"), on March 30, 2022, the SEC issued proposed rules (the "*SPAC Rule Proposals*") relating to, among other items, disclosures in business combination transactions involving SPACs and private operating companies; the condensed financial statement requirements applicable to transactions involving shell companies; the use of projections by SPACs in SEC filings in connection with proposed business combination transactions; the potential liability of certain participants in proposed business combination transactions; and the extent to which SPACs could become subject to regulation under the Investment Company Act of 1940, as amended, including a proposed rule that would provide SPACs a safe harbor from treatment as an investment company if they satisfy certain conditions that limit a SPAC's duration, asset composition, business purpose and activities.

With regard to the SEC's investment company proposals included in the SPAC Rule Proposals, while the funds in the Trust Account have, since the Company's initial public offering, been held only in U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries, to mitigate the risk of being viewed as operating an unregistered investment company (including pursuant to the subjective test of Section 3(a)(1)(A) of the Investment Company Act of 1940, as amended), the Company may, at any time, instruct Continental to hold all funds in the Trust Account in cash until the earlier of the consummation of the Business Combination, the Company's initial business combination and liquidation of the Company.

[**Table of Contents**](#TOC001)

#### What happens if the Extension Proposal is not approved or not implemented?
If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

The Sponsor and the Company's directors and officers have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any New Vista Class B Shares held by it or them, as applicable, if the Company fails to complete an initial Business Combination by February 19, 2023, although they will be entitled to liquidating distributions from the Trust Account with respect to any New Vista Class A Shares they hold if the Company fails to complete its initial Business Combination by such date. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023. The Company will pay the costs of liquidation from its remaining assets outside of the Trust Account.

#### What happens if the Redemption Limitation Amendment Proposal is not approved or not implemented?
If the Extension Proposal is approved but the Redemption Limitation Amendment Proposal is not approved or not implemented, we will not redeem public shares to the extent that, if the Redemption Limitation Amendment Proposal is not approved or not implemented, accepting all properly submitted redemption requests would cause us to have less than $5,000,001 of net tangible assets. In the event that the Redemption Limitation Amendment Proposal is not approved or not implemented and we receive notice of redemptions of public shares approaching or in excess of the Redemption Limitation, we and/or the Sponsor may take action to increase our net tangible assets to avoid the Redemption Limitation, which may include, at our and our Sponsor's option and in our and its sole discretion, any, several or all of the following actions: (a) attempting to secure waivers of certain of our significant liabilities, including the deferred underwriting fees and (b) entering into non-redemption agreements with certain of our significant shareholders. If the Redemption Limitation Amendment Proposal is not approved or not implemented and the Redemption Limitation is exceeded, either because we do not take action to increase our net tangible assets or because our attempt to do so is not successful, then we will not proceed with the amendments set forth in Annex A of the accompanying proxy statement and we will not redeem any public shares. In such case, public shares which a public shareholder elects to redeem but which are not redeemed shall be returned to such public shareholder or such public shareholder's account and such public shareholder will retain the right to have their public shares redeemed for cash if the Company has not completed an initial Business Combination by February 19, 2023.

#### If the Charter Amendment Proposals are approved, what happens next?
The Company is continuing its efforts to complete an initial Business Combination. The Company is seeking approval of the Extension because the Company may not be able to complete an initial Business Combination prior to February 19, 2023. If the Extension Proposal is approved, the Company expects to continue evaluating initial Business Combination opportunities in pursuit of entering into an initial Business Combination agreement and seeking shareholder approval of an initial Business Combination. If shareholders approve such initial Business Combination, the Company expects to consummate an initial Business Combination as soon as possible following shareholder approval and satisfaction of the other conditions to the consummation of an initial Business Combination.

[**Table of Contents**](#TOC001)

Upon approval of the Charter Amendment Proposals by the required number of votes, or approval of the Extension Proposal by the required number of votes in the event the Redemption Limitation Amendment Proposal is not approved or not implemented and as a result of the redemptions, the Redemption Limitation is not reached, the Company plans to file an amendment to the Charter with the Cayman Registrar in the form attached as <u>Annex A</u> hereto. The Company will remain a reporting company under the Exchange Act, and its units, New Vista Class A Shares and public warrants will remain publicly traded. Assuming the Extension Proposal is approved, if our Board abandons the Redemption Limitation Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

If any of the Charter Amendment Proposals are approved and implemented, any removal of any Withdrawal Amount from the Trust Account will reduce the amount remaining in the Trust Account and increase the percentage interest of shares of public held by the Sponsor through the shares of New Vista Class B Shares. If the Redemption Limitation Amendment Proposal is approved and implemented, the Company will redeem public shares irrespective of the prior Redemption Limitation. Only if the Redemption Limitation Amendment Proposal is not approved or not implemented, we will not proceed with the Extension if redemptions of public shares cause us to have less than $5,000,001 of net tangible assets following approval of the Extension Proposal, as provided in the Charter.

If the Extension is approved, the Sponsor will continue to receive payments from the Company of $10,000 per month for office space, utilities and secretarial and administrative services pursuant to the Administrative Services Agreement, dated as of February 16, 2021, by and between the Company and the Sponsor (the "*Administrative Services Agreement*").

***If (i) the Charter Amendment Proposals are approved and we amend the Charter, or (ii) the Redemption Limitation is exceeded, will our securities remain listed on Nasdaq Capital Market following shareholder redemptions?***

Our public shares, units and warrants are listed on the Nasdaq Capital Market. We are subject to compliance with Nasdaq's continued listing requirements in order to maintain the listing of our securities on Nasdaq. Such continued listing requirements for our public shares include, among other things, the requirement to maintain at least 300 public holders, at least 500,000 publicly held shares and the Market Value of Listed Securities (as defined in Nasdaq Rule 5005) of at least $35 million. Pursuant to the terms of our Charter, in connection with the Charter Amendment Proposals, public shareholders may elect to redeem their public shares and, as a result, we may not be in compliance with Nasdaq's continued listing requirements.

If our securities do not meet Nasdaq's continued listing requirements, Nasdaq may delist our securities from trading on its exchange. If Nasdaq delists any of our securities from trading on its exchange and we are not able to list such securities on another approved national securities exchange, we expect that such securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including: (i) a limited availability of market quotations for our securities, (ii) reduced liquidity for our securities, (iii) a determination that our public shares are "penny stocks" which will require brokers trading in our public shares to adhere to more stringent rules, including being subject to the depository requirements of Rule 419 of the Securities Act, and possibly result in a reduced level of trading activity in the secondary trading market for our securities, (iv) a decreased ability to issue additional securities or obtain additional financing in the future, and (v) a less attractive acquisition vehicle to a target business in connection with an initial Business Combination.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as "covered securities." Our public shares, units and warrants qualify as covered securities under such statute. If we were no longer listed on Nasdaq, our securities would not qualify as covered securities under such statute and we would be subject to regulation in each state in which we offer our securities.

#### Where will I be able to find the voting results of the Extraordinary General Meeting?
We will announce preliminary voting results at the Extraordinary General Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four (4) business days after the Extraordinary General Meeting. If final voting results are not available to us in time to file a Current Report on

[**Table of Contents**](#TOC001)

Form 8-K within four (4) business days after the Extraordinary General Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to such Current Report on Form 8-K as soon as they become available.

#### Would I still be able to exercise my redemption rights in connection with a vote to approve a proposed initial Business Combination?
Yes. Assuming you are a shareholder as of the record date for voting on a proposed initial Business Combination, you will be able to vote on a proposed initial Business Combination. If you disagree with an initial Business Combination, you will retain your right to redeem your shares of New Vista Class A Shares upon consummation of such initial Business Combination, subject to any limitations set forth in our Charter, as amended. Such limitations include that a public shareholder, together with any affiliate of such public shareholder or any other person with whom such public shareholder is acting in concert or as a group for purposes of acquiring, holding or disposing of New Vista Shares will be restricted from redeeming its New Vista Class A Shares with respect to more than 15% of the New Vista Class A Shares sold in the IPO. Accordingly, if a public shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the New Vista Class Shares sold in the IPO, then any such shares in excess of that 15% limit would not be redeemed for cash, without our prior consent.

#### How do I change my vote?
If you have submitted a proxy to vote your shares and wish to change your vote, you may send a later-dated, signed proxy card to the Company's Secretary at 125 South Wacker Drive, Suite 300, Chicago, IL 60606, so that it is received by the Company's Secretary prior to the vote at the Extraordinary General Meeting (which is scheduled to take place on February 10, 2023). Shareholders also may revoke their proxy by sending a notice of revocation to the Company's Secretary, which must be received by the Company's Secretary prior to the vote at the Extraordinary General Meeting, or by attending the Extraordinary General Meeting, revoking their proxy and voting in person (including by virtual means). Attendance at the Extraordinary General Meeting alone will not change your vote. However, if your shares are held in "street name" by your broker, bank or another nominee, you must contact your broker, bank or other nominee to change your vote.

#### How are votes counted?
Votes will be counted by the inspector of election appointed for the meeting, who will separately count "FOR" and "AGAINST" votes, abstentions and broker non-votes for each of the proposals. A shareholder's failure to vote by proxy or to vote in person or virtually at the Extraordinary General Meeting will not be counted towards the number of shares required to validly establish a quorum, and if a valid quorum is otherwise established, will have no effect on the proposals. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals. We believe that each of the proposals is a "non-discretionary" matter, and therefore, there will not be any broker non-votes at the Extraordinary General Meeting.

#### If my shares are held in "street name," will my broker automatically vote them for me?
If you do not give instructions to your broker, your broker can vote your shares with respect to "discretionary" items, but not with respect to "non-discretionary" items. We believe that each of the proposals are "non-discretionary" items.

Your broker can vote your shares with respect to "non-discretionary" items only if you provide instructions on how to vote. You should instruct your broker to vote your shares. Your broker can tell you how to provide these instructions. If you do not give your broker instructions, your shares will be treated as broker non-votes with respect to all proposals. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals.

#### What is a quorum?
A quorum is the minimum number of shares required to be present at the Extraordinary General Meeting for the Extraordinary General Meeting to be properly held under our Charter and Cayman Islands law. The presence, in person, virtually, by proxy, or, if a corporation or other non-natural person, by its duly authorized representative or

[**Table of Contents**](#TOC001)

proxy, of the holders of a majority of the issued and outstanding New Vista Shares entitled to vote at the Extraordinary General Meeting constitutes a quorum. Proxies that are marked "abstain" and proxies relating to "street name" shares that are returned to us but marked by brokers as "not voted" (so-called "broker non-votes") will be treated as shares present for purposes of determining the presence of a quorum on all matters. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on "non-discretionary" matters. We believe that each of the proposals is a "non-discretionary" matter.

#### Who can vote at the Extraordinary General Meeting?
Holders of New Vista Shares as of the close of business on the Record Date are entitled to vote at the Extraordinary General Meeting. On the Record Date, there were 34,500,000 New Vista Shares issued and outstanding, including (a) 27, 6000,000 New Vista Class A Shares and (b) 6, 9000,000 New Vista Class B Shares. The Company's warrants do not have voting rights in connection with the proposals.

In deciding all matters at the Extraordinary General Meeting, each shareholder will be entitled to one (1) vote for each share held by them on the Record Date. Holders of New Vista Class A Shares and holders of New Vista Class B Shares will vote together as a single class on all matters submitted to a vote of our shareholders except as required by law. The Initial Shareholders collectively own all of our issued and outstanding New Vista Class B Shares, constituting approximately 20% of our issued and outstanding New Vista Shares.

*Registered Shareholders.* If our shares are registered directly in your name with our transfer agent, Continental, you are considered the shareholder of record with respect to those shares. As the shareholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote in person at the Extraordinary General Meeting.

"*Street Name*" *Shareholders*. If our shares are held on your behalf in a brokerage account or by a bank or other nominee, you are considered the beneficial owner of those shares held in "street name," and your broker or nominee is considered the shareholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker or nominee as to how to vote your shares. However, since a beneficial owner is not the shareholder of record, you may not vote your New Vista Shares at the Extraordinary General Meeting unless you follow your broker's procedures for obtaining a legal proxy. Throughout this proxy statement, we refer to shareholders who hold their shares through a broker, bank or other nominee as "street name shareholders."

#### Does the Board recommend voting for the approval of the proposals?
Yes. After careful consideration of the terms and conditions of these proposals, the Board has determined that each of the proposals are in the best interests of the Company and its shareholders. The Board recommends that the Company's shareholders vote "FOR" each of the proposals.

#### What interests do the Company's directors and officers have in the approval of the proposals?
The Company's directors and officers have interests in the proposals that may be different from, or in addition to, your interests as a shareholder. These interests include ownership of shares of New Vista Class B Shares, private placement warrants that may become exercisable in the future, any loans by them to the Company that will not be repaid in the event of our winding up and the possibility of future compensatory arrangements. See the section entitled "*Proposal No. 1 — The Extension Proposal — Interests of the Sponsor and the Company's Directors and Officers*" for more information.

#### Are there any appraisal, dissenters or similar rights for dissenting shareholders?
Neither Cayman Islands law nor our Charter provides for dissenters' rights for dissenting shareholders in connection with any of the proposals to be voted upon at the Extraordinary General Meeting. Warrant holders do not have appraisal rights in connection with any of the proposals to be voted upon at the Extraordinary General Meeting.

[**Table of Contents**](#TOC001)

#### What happens to the Company's warrants if the Extension Proposal is not approved or not implemented?
If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023.

#### What happens to the Company's warrants if the Extension Proposal is approved?
If the Extension is approved, the Company will continue to attempt to consummate an initial Business Combination until the Extended Date, and will retain the blank check company restrictions previously applicable to it. The warrants will remain outstanding in accordance with their terms.

#### How do I vote?
If you are a holder of record of New Vista Shares as of the close of business on the Record Date, you may vote in person or by virtual attendance at the Extraordinary General Meeting or by submitting a proxy for the Extraordinary General Meeting. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage-paid envelope. If you hold your shares in "street name," which means your shares are held of record by a broker, bank or other nominee, you should contact your broker, bank or other nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or other nominee with instructions on how to vote your shares or, if you wish to attend the Extraordinary General Meeting and vote in person, obtain a valid proxy from your broker, bank or other nominee. If you hold your shares in "street name" and wish to vote online by virtually attending the Extraordinary General Meeting, you must email a copy (a legible photograph is sufficient) of your legal proxy to Continental at proxy@continentalstock.com. If you email a valid legal proxy, you will be issued a 12-digit meeting control number that will allow you to register to attend and participate in the Extraordinary General Meeting.

#### How do I redeem my New Vista Shares?
Pursuant to the Charter, a public shareholder may request that the Company redeem all or a portion of such public shareholder's public shares for cash if any of the Charter Amendment Proposals are approved by the requisite vote of shareholders and implemented. You will be entitled to receive cash for any public shares to be redeemed only if you:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) (i) hold public shares or (ii) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares and (c) such redemption would not result in the Company having net tangible assets of less than $5,000,001 (unless the Redemption Limitation Amendment Proposal is approved and implemented); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) prior to 5:00 p.m., New York City time, on February 8, 2023 (two (2) business days prior to the vote at the Extraordinary General Meeting), (i) submit a written request to Continental, the Company's transfer agent, that the Company redeem your public shares for cash and (ii) tender or deliver your shares (and share certificates (if any) and other redemption forms) to the transfer agent, physically or electronically through The Depository Trust Company.

[**Table of Contents**](#TOC001)

Any demand for redemption, once submitted to the Company, may not be withdrawn unless the directors of the Company determine (in their sole discretion) to permit the withdrawal of such redemption request (which they may do in whole or in part). If you tendered or delivered your shares for redemption to Continental and decide within the required timeframe not to exercise your redemption rights, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the phone number or address listed under the question "Who can help answer my questions?" below.

Additionally, we will not redeem shares if (i) none of the Charter Amendment Proposals are approved, (ii) none of the Charter Amendment Proposals are implemented (even if approved), or (iii) the Redemption Limitation Amendment Proposal is not approved or not implemented and redemptions would cause the Redemption Limitation to be exceeded. In any of these scenarios, you will not receive cash for public shares. In the event that the Redemption Limitation Amendment Proposal is not approved or not implemented and we receive notice of redemptions of public shares approaching or in excess of the Redemption Limitation, we and/or the Company's sponsor, New Vista Acquisition Sponsor LLC, a Delaware limited liability company, may take action to increase our net tangible assets to avoid the Redemption Limitation, which may include, at our and our Sponsor's option and in our and its sole discretion, any, several or all of the following actions: (a) attempting to secure waivers of certain of our significant liabilities, including the deferred underwriting fees and (b) entering into non-redemption agreements with certain of our significant shareholders. If the Redemption Limitation Amendment Proposal is not approved or not implemented and the Redemption Limitation is exceeded, either because we do not take action to increase our net tangible assets or because our attempt to do so is not successful, then we will not proceed with the amendments set forth in <u>Annex A</u> of the accompanying proxy statement and we will not redeem any public shares. In such case, public shares which a public shareholder elects to redeem but which are not redeemed shall be returned to such public shareholder or such public shareholder's account and such public shareholder will retain the right to have their public shares redeemed for cash if the Company has not completed an initial Business Combination by February 19, 2023.

Holders of units of the Company must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank, as applicable, that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, their own name, the holder must contact Continental directly and instruct it to do so. Your broker, bank or other nominee may have an earlier deadline by which you must provide instructions to separate the units into the underlying public shares and public warrants in order to exercise redemption rights with respect to the public shares, so you should contact your broker, bank or other nominee or intermediary. **<u>Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Charter Amendment Proposals.</u>**

#### What should I do if I receive more than one (1) set of voting materials?
You may receive more than one (1) set of voting materials, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards, if your shares are registered in more than one (1) name or are registered in different accounts. For example, if you hold your shares in more than one (1) brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your shares.

#### Who is paying for this proxy solicitation?
Our Board is soliciting proxies for use at the Extraordinary General Meeting. All costs associated with this solicitation will be borne directly by the Company. We have engaged Morrow to assist in the solicitation of proxies for the Extraordinary General Meeting. We have agreed to pay Morrow a fee of $35,000, *plus* disbursements, and indemnify Morrow and its affiliates against certain claims, liabilities, losses, damages and expenses for their services as the Company's proxy solicitor. We will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of New Vista Class A Shares for their expenses in forwarding soliciting materials to beneficial owners of New Vista Class A Shares and in obtaining voting instructions from those owners. Our directors and officers may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

#### RISK FACTOR
**Our initial Business Combination may be delayed or ultimately prohibited if such initial Business Combination is subject to regulatory review and approval requirements, including pursuant to foreign investment regulations and review by governmental entities such as CFIUS.**

Our initial Business Combination may be subject to regulatory review and approval requirements by governmental entities, which may cause such Business Combination to be delayed or ultimately prohibited. For example, CFIUS has authority to review direct or indirect foreign investments in U.S. companies. Among other things, CFIUS is empowered to require certain foreign investors to make mandatory filings, to charge filing fees related to such filings, and to self-initiate national security reviews of foreign direct and indirect investments in U.S. companies if the parties to that investment choose not to file voluntarily. If CFIUS determines that an investment threatens national security, CFIUS has the power to impose restrictions on the investment or recommend that the President prohibit and/or unwind it. Whether CFIUS has jurisdiction to review an acquisition or investment transaction depends on, among other factors, the nature and structure of the transaction, the nationality of the parties, the level of beneficial ownership interest and the nature of any information or governance rights involved.

In connection with our initial Business Combination, we may determine that we will submit to CFIUS review on a voluntary basis, or to proceed with the transaction without submitting to CFIUS and risk CFIUS intervention, before or after closing the transaction. CFIUS may decide to block or delay such Business Combination, or impose conditions with respect to such Business Combination, which may delay or prevent us from consummating such Business Combination. As a result of potential CFIUS or other regulatory review or intervention, the pool of potential targets with which the Company can complete an initial Business Combination may be limited.

The process of government review, whether by CFIUS or otherwise, could be lengthy. Because we have only a limited time to complete our initial Business Combination, our failure to obtain any required approvals within the requisite time period may require us to liquidate. If we are unable to consummate our initial Business Combination within the applicable time period required, including as a result of extended regulatory review, we will (i) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

#### THE EXTRAORDINARY GENERAL MEETING

#### Date, Time, Place and Purpose of the Extraordinary General Meeting
The Extraordinary General Meeting will be held in person or by proxy on February 10, 2023, at 10:00 a.m., New York City time, at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, located at One Manhattan West, New York, New York 10001, or virtually via live webcast at *www.cstproxy.com/newvistacap/2023*, to consider and vote upon the proposals to be put to the Extraordinary General Meeting. While shareholders are encouraged to attend the meeting virtually, you will be permitted to attend the Extraordinary General Meeting in person at the offices of Skadden, Arps, Slate, Meagher & Flom LLP only if you (i) are fully vaccinated against COVID-19 and show proof of such vaccination, (ii) complete a visitor health form upon arrival and (iii) reserve your attendance at least two business days in advance of the Extraordinary General Meeting by contacting Skadden, Arps, Slate, Meagher & Flom LLP, at One Manhattan West, New York, NY 10001, telephone (212) 735-3000.

At the Extraordinary General Meeting, you will be asked to consider and vote on proposals to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Proposal No. 1 — The Extension Proposal** — as a special resolution, to amend the Company's Charter pursuant to an amendment to the Charter in the form set forth in <u>Annex A</u> of the accompanying proxy statement to extend the date by which the Company must either (i) consummate a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination, which we refer to as our initial Business Combination, or (ii) cease its operations except for the purpose of winding up if it fails to complete such initial Business Combination and (iii) redeem all of the New Vista Class A Shares, par value $0.0001 per share, of the Company, from February 19, 2023, to the Extended Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Proposal No. 2 — The Redemption Limitation Amendment Proposal —** as a special resolution, to amend the Company's Charter pursuant to an amendment to the Charter in the form set forth in <u>Annex A</u> of the accompanying proxy statement to eliminate from the Charter the limitation that the Company may not redeem public shares to the extent that such redemption would result in the Company having net tangible assets of less than $5,000,001 in order to allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Proposal No. 3 — The Liquidation Amendment Proposal** — a proposal to amend the Charter as set forth in <u>Annex A</u> of the accompanying proxy statement to permit our Board, in its sole discretion, to elect to wind up our operations on an earlier date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) **Proposal No. 4 — The Trust Amendment Proposal** — a proposal to amend the Trust Agreement, pursuant to an amendment to the Trust Agreement in the form set forth in <u>Annex B</u> of the accompanying proxy statement to extend the date by which the Company would be required to consummate our initial Business Combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) **Proposal No. 5 — The Adjournment Proposal** — as an ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of any of the Charter Amendment Proposals, which will only be presented at the Extraordinary General Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Extraordinary General Meeting to approve any of the Charter Amendment Proposals.

#### Voting Power; Record Date
Only shareholders of record of the Company as of the close of business on the Record Date are entitled to notice of, and to vote at, the Extraordinary General Meeting or any adjournment or postponement thereof. Each of the New Vista Shares entitles the holder thereof to one (1) vote. On the Record Date, there were 34,500,000 New Vista Shares issued and outstanding, including (a) 27,600,000 New Vista Class A Shares and (b) 6,900,000 New Vista Class B Shares. The Company's warrants do not have voting rights in connection with the proposals.

[**Table of Contents**](#TOC001)

#### Quorum and Vote of Shareholders
A quorum is the minimum number of shares required to be present at the Extraordinary General Meeting for the Extraordinary General Meeting to be properly held under our Charter and Cayman Islands law. The presence, in person, virtually, by proxy, or, if a corporation or other non-natural person, by its duly authorized representative or proxy, of the holders of a majority of the issued and outstanding New Vista Shares entitled to vote at the Extraordinary General Meeting constitutes a quorum. Proxies that are marked "abstain" and proxies relating to "street name" shares that are returned to us but marked by brokers as "not voted" (so-called "broker non-votes") will be treated as shares present for purposes of determining the presence of a quorum on all matters. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on "non-discretionary" matters. We believe that each of the proposals is a "non-discretionary" matter.

#### Votes Required
Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals.

Approval of the Redemption Limitation Amendment requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals.

Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who vote at the Extraordinary General Meeting. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals.

If you do not want any of the proposals to be approved, you must vote against such proposal. A shareholder's failure to vote by proxy or to vote in person at the Extraordinary General Meeting will not be counted towards the number of New Vista Shares required to validly establish a quorum. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals. We believe that each of the proposals is a "non-discretionary" matter, and therefore, there will not be any broker non-votes at the Extraordinary General Meeting.

#### Voting
You can vote your shares at the Extraordinary General Meeting in person, by proxy or online by virtually attending the Extraordinary General Meeting. If your shares are owned directly in your name with our transfer agent, Continental, you are considered, with respect to those shares, the "shareholder of record." If your shares are held in a stock brokerage account or by a bank or other nominee or intermediary, you are considered the beneficial owner of shares held in "street name" and are considered a "non-record (beneficial) shareholder."

*Shareholders of Record*

You can vote by proxy by having one (1) or more individuals who will be at the Extraordinary General Meeting vote your shares for you. These individuals are called "proxies" and using them to cast your ballot at the Extraordinary General Meeting is called voting "by proxy." If you wish to vote by proxy, you must (a) complete the enclosed form, called a "proxy card," and mail it in the envelope provided or (b) submit your proxy over the Internet in accordance with the instructions on the enclosed proxy card. If you complete the proxy card and mail it in the envelope provided or submit your proxy over the Internet as described above, you will designate each of Dennis A. Muilenburg and Travis S. Nelson to act as your proxy at the Extraordinary General Meeting. One (1) of the aforementioned individuals

[**Table of Contents**](#TOC001)

will then vote your shares at the Extraordinary General Meeting in accordance with the instructions you have given them in the proxy card with respect to the proposals presented in this proxy statement. Proxies will extend to, and be voted at, any adjournments or postponements of the Extraordinary General Meeting.

Alternatively, you can vote your shares online by virtually attending the Extraordinary General Meeting.

*Beneficial Owners*

If your shares are held in an account through a broker, bank or other nominee or intermediary, you must instruct the broker, bank or other nominee how to vote your shares by following the instructions that the broker, bank or other nominee provides you along with this proxy statement. Your broker, bank or other nominee may have an earlier deadline by which you must provide instructions to it as to how to vote your shares, so you should read carefully the materials provided to you by your broker, bank or other nominee or intermediary.

If you wish to attend and vote your shares at the Extraordinary General Meeting, you must first obtain a legal proxy from your broker, bank or other nominee that holds your shares and email a copy (a legible photograph is sufficient) of your legal proxy to Continental at proxy@continentalstock.com. Beneficial owners who email a valid legal proxy will be issued a 12-digit meeting control number that will allow them to register to attend and participate in the Extraordinary General Meeting. Beneficial owners who wish to attend the Extraordinary General Meeting virtually must obtain a legal proxy from the shareholder of record and email a copy of their legal proxy to proxy@continentalstock.com.

If you do not provide voting instructions to your bank, broker or other nominee or intermediary and you do not vote your shares at the Extraordinary General Meeting, your shares will not be voted on any proposal on which your bank, broker or other nominee does not have discretionary authority to vote. In these cases, the bank, broker or other nominee or intermediary will not be able to vote your shares on those matters for which specific authorization is required. We believe each of the proposals constitutes a "non-discretionary" matter.

*Proxies*

Our Board is asking for your proxy. Giving our Board your proxy means you authorize it to vote your shares at the Extraordinary General Meeting in the manner you direct. You may vote for or withhold your vote for each proposal or you may abstain from voting. All valid proxies received prior to the Extraordinary General Meeting will be voted. All shares represented by a proxy will be voted, and where a shareholder specifies by means of the proxy a choice with respect to any matter to be acted upon, the shares will be voted in accordance with the specification so made. If no choice is indicated on the proxy, the shares will be voted "FOR" each of the proposals and as the proxy holders may determine in their discretion with respect to any other matters that may properly come before the Extraordinary General Meeting.

Proxies that are marked "abstain" and proxies relating to "street name" shares that are returned to us but marked by brokers as "not voted" (so-called "broker non-votes") will be treated as shares present for purposes of determining the presence of a quorum on all matters. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on "non-discretionary" matters. We believe each of the proposals constitutes a "non-discretionary" matter.

Shareholders who have questions or need assistance in completing or submitting their proxy cards should contact our proxy solicitor, Morrow, at (800) 662-5200 or by sending a letter to 333 Ludlow Street, 5<sup>th</sup> Floor, South Tower, Stamford, CT 06902, or by emailing NVSA.info@investor.morrowsodali.com.

#### Revocability of Proxies
Shareholders may send a later-dated, signed proxy card to the Company's Secretary at 125 South Wacker Drive, Suite 300, Chicago, IL 60606, so that it is received by the Company's Secretary prior to the vote at the Extraordinary General Meeting (which is scheduled to take place on February 10, 2023). Shareholders also may revoke their proxy by sending a notice of revocation to the Company's Secretary, which must be received by the Company's Secretary prior to the vote at the Extraordinary General Meeting, or by attending the Extraordinary General Meeting, revoking their proxy and voting in person (including by virtual means). Attendance at the Extraordinary General Meeting alone will not change your vote. However, if your shares are held in "street name" by your broker, bank or another nominee, you must contact your broker, bank or other nominee to change your vote.

[**Table of Contents**](#TOC001)

#### Attendance at the Extraordinary General Meeting
Only shareholders, their proxy holders and guests we may invite may attend the Extraordinary General Meeting. If you wish to virtually attend the Extraordinary General Meeting but you hold your shares through a broker, bank or other agent, you must follow the instructions detailed above on how to attend the Extraordinary General Meeting.

#### Solicitation of Proxies
Our Board is soliciting proxies for use at the Extraordinary General Meeting. All costs associated with this solicitation will be borne directly by the Company. We have engaged Morrow to assist in the solicitation of proxies for the Extraordinary General Meeting. We have agreed to pay Morrow a fee of $35,000, *plus* disbursements, and indemnify Morrow and its affiliates against certain claims, liabilities, losses, damages and expenses for their services as the Company's proxy solicitor. We will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of New Vista Class A Shares for their expenses in forwarding soliciting materials to beneficial owners of New Vista Class A Shares and in obtaining voting instructions from those owners. Our directors and officers may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

You may contact Morrow at:

Morrow Sodali LLC<br>333 Ludlow Street<br>5<sup>th</sup> Floor, South Tower<br>Stamford, CT 06902<br>Individuals (toll-free): (800) 662-5200<br>Banks and brokerage firms, please call collect: (203) 658-9400<br>Email: NVSA.info@investor.morrowsodali.com

If any additional solicitation of the holders of our outstanding New Vista Shares is deemed necessary, we (through our directors and officers) anticipate making such solicitation directly.

#### Dissenters' Rights and Appraisal Rights
Neither Cayman Islands law nor our Charter provides for dissenters' rights for dissenting shareholders in connection with any of the proposals to be voted upon at the Extraordinary General Meeting.

Warrant holders do not have appraisal rights in connection with any of the proposals to be voted upon at the Extraordinary General Meeting.

#### Other Business
The Board does not know of any other matters to be presented at the Extraordinary General Meeting. The form of proxy accompanying this proxy statement confers discretionary authority upon the named proxy holders with respect to amendments or variations to the matters identified in the accompanying Notice of the Extraordinary General Meeting and with respect to any other matters that may properly come before the Extraordinary General Meeting. If any additional matters are properly presented at the Extraordinary General Meeting, or at any adjournments or postponements of the Extraordinary General Meeting, the persons named in the enclosed proxy card will have discretion to vote the shares they represent in accordance with their own judgment on such matters. We expect that the New Vista Class A Shares represented by properly submitted proxies will be voted by the proxy holders in accordance with the recommendations of our Board with respect to any such matters.

#### Principal Executive Offices
Our principal executive offices are located at 125 South Wacker Drive, Suite 300, Chicago, IL 60606. Our telephone number is (312) 855-2083. Our corporate website address is *www.newvistacap.com*. Our website and the information contained on, or that can be accessed through, the website is not deemed to be incorporated by reference in, and is not considered part of, this proxy statement.

[**Table of Contents**](#TOC001)

#### PROPOSAL NO. 1 — THE EXTENSION PROPOSAL

#### Background
We are a blank check company, incorporated on December 21, 2020, as a Cayman Islands exempted company and incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses.

On February 19, 2021, New Vista consummated its IPO of its units, with each unit consisting of one (1) New Vista Class A Share and one-third of one redeemable warrant to purchase one (1) New Vista Class A Share, which included the full exercise by the underwriters of their over-allotment option in the amount of 3,600,000 units. Simultaneously with the closing of the IPO, New Vista completed the private sale of 5,680,000 private placement warrants at a purchase price of $1.50 per private placement warrant to the Sponsor, generating gross proceeds to us of $8,520,000. Following the closing of New Vista's IPO, a total of $276,000,000 ($10.00 per unit) of the net proceeds from the IPO and the sale of the private placement warrants was placed in the Trust Account, with Continental acting as trustee.

#### Reasons for the Extension Proposal
The Charter provides that we have until February 19, 2023, to complete an initial Business Combination. The Board has determined that there may not be sufficient time before February 19, 2023, to hold an extraordinary general meeting to obtain shareholder approval of and consummate an initial Business Combination. Accordingly, the Board believes that in order to be able to successfully complete an initial Business Combination, it is appropriate to continue the Company's existence until the Extended Date. The Board believes that an initial Business Combination is in the best interests of the Company and our shareholders. Therefore, the Board has determined that it is in the best interests of our shareholders to extend the date by which the Company must complete an initial Business Combination to the Extended Date.

If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

We believe that the provisions of the Charter described in the preceding paragraph were included to protect the Company's shareholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable initial Business Combination in the timeframe contemplated by the Charter. We also believe, however, that given the Company's expenditure of time, effort and money on pursuing an initial Business Combination and our belief that the Business Combination is in the best interest of New Vista and our shareholders, the Extension is warranted.

The sole purpose of the Extension Proposal is to provide the Company with sufficient time to complete an initial Business Combination, which the Board believes is in the best interests of the Company and our shareholders. A copy of the proposed amendment to the Charter is attached to this proxy statement as <u>Annex A</u>.

**You are not being asked to vote on an initial Business Combination at this time. If any of the Charter Amendment Proposals are approved and implemented and you do not elect to redeem your public shares in connection with the Charter Amendment Proposals, you will retain the right to vote on an initial Business Combination if and when such transaction is submitted to shareholders and the right to redeem your public shares for cash from the Trust Account in the event a proposed initial Business Combination is approved and completed or the Company has not consummated an initial Business Combination by the Extended Date. If an initial Business Combination is not consummated by the Extended Date, assuming the Extension is implemented, the Company will redeem its public shares.**

#### If the Extension Proposal is Not Approved or Not Implemented
If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

The Sponsor and the Company's directors and officers have agreed to waive their respective rights to liquidating distributions from the Trust Account in respect of any New Vista Class B Shares held by it or them, as applicable, if the Company fails to complete an initial Business Combination by February 19, 2023, although they will be entitled to liquidating distributions from the Trust Account with respect to any New Vista Class A Shares they hold if the Company fails to complete its initial Business Combination by such date. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023. The Company will pay the costs of liquidation from its remaining assets outside of the Trust Account.

#### If the Extension Proposal Is Approved
If the Extension Proposal is approved, the Company will file an amendment to the Charter with the Cayman Registrar in the form of <u>Annex A</u> hereto to extend the time it has to complete an initial Business Combination until the Extended Date. The Company will remain a reporting company under the Exchange Act, and its units, New Vista Class A Shares and public warrants will remain publicly traded. The Company will then continue to work to consummate its initial Business Combination by the Extended Date.

Notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the filing with the Cayman Registrar. Assuming the Extension Proposal is approved, if our Board abandons the Redemption Limitation Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

If the Extension Proposal is approved, and the Extension is implemented, the amount held in the Trust Account will be reduced by withdrawals in connection with any shareholder redemptions. The Company cannot predict the amount that will remain in the Trust Account if the Extension is approved, and the amount remaining in the Trust Account may be significantly less than the approximately $277,450,461 that was in the Trust Account as of September 30, 2022. If the Redemption Limitation Amendment Proposal is not approved or not implemented, we will not proceed with the Extension if the number of redemptions of our public shares cause us to have less than $5,000,001 of net tangible assets following approval of the Extension Proposal, as provided in the Charter.

If the Extension is approved, the Sponsor will continue to receive payments from the Company of $10,000 per month for office space, utilities and secretarial and administrative services pursuant to the Administrative Services Agreement.

#### Redemption Rights
If the Extension Proposal is approved, and the Extension is implemented, each public shareholder may seek to redeem his, her or its public shares. Holders of public shares who do not elect to redeem their public shares in connection with the Extension will retain the right to redeem their public shares in connection with any shareholder vote to approve a proposed initial Business Combination, or if the Company has not consummated an initial Business Combination by the Extended Date.

[**Table of Contents**](#TOC001)

**TO DEMAND REDEMPTION, YOU MUST ENSURE YOUR BANK OR BROKER COMPLIES WITH THE REQUIREMENTS IDENTIFIED HEREIN, INCLUDING SUBMITTING A WRITTEN REQUEST THAT YOUR SHARES BE REDEEMED FOR CASH TO THE TRANSFER AGENT AND TENDERING AND DELIVERING YOUR SHARES (AND SHARE CERTIFICATES (IF ANY) AND OTHER REDEMPTION FORMS) TO THE TRANSFER AGENT PRIOR TO 5:00 P.M. NEW YORK CITY TIME ON FEBRUARY 8, 2023. You will only be entitled to receive cash in connection with a redemption of these shares if you continue to hold them until the effective date of the Extension and redemptions.**

Pursuant to the Charter, a public shareholder may request that the Company redeem all or a portion of such public shareholder's public shares for cash if the Extension Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) (i) hold public shares or (ii) hold public shares as part of units and elect to separate such units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares and (iii) such redemption would not result in the Company having net tangible assets of less than $5,000,001 (unless the Redemption Limitation Amendment Proposal is approved and implemented); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) prior to 5:00 p.m., New York City time, on February 8, 2023 (two (2) business days prior to the vote at the Extraordinary General Meeting), (i) submit a written request to Continental, the Company's transfer agent, that the Company redeem your public shares for cash and (ii) tender or deliver your shares (and share certificates (if any) and other redemption forms) to the transfer agent, physically or electronically through The Depository Trust Company.

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, their own name, the holder must contact the transfer agent directly and instruct it to do so. Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Charter Amendment Proposals.

Additionally, we will not redeem shares if (i) none of the Charter Amendment Proposals are approved, (ii) none of the Charter Amendment Proposals are implemented (even if approved), or (iii) the Redemption Limitation Amendment Proposal is not approved or not implemented and redemptions would cause the Redemption Limitation to be exceeded. In any of these scenarios, you will not receive cash for public shares. In the event that the Redemption Limitation Amendment Proposal is not approved or not implemented and we receive notice of redemptions of public shares approaching or in excess of the Redemption Limitation, we and/or the Company's sponsor, New Vista Acquisition Sponsor LLC, a Delaware limited liability company, may take action to increase our net tangible assets to avoid the Redemption Limitation, which may include, at our and our Sponsor's option and in our and its sole discretion, any, several or all of the following actions: (a) attempting to secure waivers of certain of our significant liabilities, including the deferred underwriting fees and (b) entering into non-redemption agreements with certain of our significant shareholders. If the Redemption Limitation Amendment Proposal is not approved or not implemented and the Redemption Limitation is exceeded, either because we do not take action to increase our net tangible assets or because our attempt to do so is not successful, then we will not proceed with the amendments set forth in <u>Annex A</u> of the accompanying proxy statement and we will not redeem any public shares. In such case, public shares which a public shareholder elects to redeem but which are not redeemed shall be returned to such public shareholder or such public shareholder's account and such public shareholder will retain the right to have their public shares redeemed for cash if the Company has not completed an initial Business Combination by February 19, 2023.

Holders of units of the Company must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank, as applicable, that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its, their own name, the holder must contact Continental directly and instruct it to do so. Your broker, bank or other nominee may have an earlier deadline by which you must provide instructions to separate the units into the underlying public shares and public warrants in order to exercise redemption rights with respect to the public shares, so you should contact your broker, bank or other nominee or intermediary. **<u>Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Charter Amendment Proposals.</u>**

[**Table of Contents**](#TOC001)

Through the Deposit Withdrawal at Custodian ("*DWAC*") system, this electronic delivery process can be accomplished by the shareholder, whether or not it is a record holder or its shares are held in "street name," by contacting the transfer agent or its broker and requesting delivery of its shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical share certificate, a shareholder's broker and/or clearing broker, The Depository Trust Company and the Company's transfer agent will need to act together to facilitate this request. There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge a tendering broker fee and the broker would determine whether or not to pass this cost on to the redeeming holder. It is the Company's understanding that shareholders should generally allot at least two (2) weeks to obtain physical certificates from the transfer agent. The Company does not have any control over this process or over the brokers or The Depository Trust Company, and it may take longer than two (2) weeks to obtain a physical share certificate. Such shareholders will have less time to make their investment decision than those shareholders that deliver their shares through the DWAC system. Shareholders who request physical share certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus may be unable to redeem their shares.

Certificates that have not been tendered in accordance with these procedures prior to the vote on the Extension Proposal will not be redeemed for cash held in the Trust Account. In the event that a public shareholder tenders its shares and decides prior to the vote at the Extraordinary General Meeting that it does not want to redeem its shares, the shareholder may withdraw the tender with the consent of the Board. If you tendered or delivered your shares for redemption to our transfer agent and decide prior to the vote at the Extraordinary General Meeting not to redeem your shares, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the address listed above. In the event that a public shareholder tenders shares and the Extension is not approved, these shares will not be redeemed and the physical certificates representing these shares will be returned to the shareholder promptly following the determination that the Extension will not be approved. The transfer agent will hold the certificates of public shareholders that make the election until such shares are redeemed for cash or returned to such shareholders.

If properly demanded, the Company will redeem each public share for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (net of taxes payable), *divided by* the number of then-issued and outstanding New Vista Class A Shares. Based upon the amount held in the Trust Account as of September 30, 2022, which was $277,450,461, the Company estimates that the per-share price at which public shares may be redeemed from cash held in the Trust Account will be approximately $10.05 at the time of the Extraordinary General Meeting. The closing price of a New Vista Class Share on January 11, 2023 was $10.12. The Company cannot assure shareholders that they will be able to sell their New Vista Class A Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

If you exercise your redemption rights, you will be exchanging your New Vista Class A Shares for cash and will no longer own such shares. You will be entitled to receive cash for these shares only if you properly demand redemption and tender your share certificate(s) to the Company's transfer agent prior to the vote on the Charter Amendment Proposals. The Company anticipates that a public shareholder who tenders shares for redemption in connection with the vote to approve the Charter Amendment Proposals would receive payment of the redemption price for such shares soon after the completion of the Charter Amendment Proposals.

#### U.S. Federal Income Tax Considerations for Shareholders Exercising Redemption Rights
The following is a discussion of U.S. federal income tax considerations generally applicable to U.S. Holders (as defined below) that elect to have their New Vista Class A Shares redeemed for cash if any of the Charter Amendment Proposals are approved and implemented. This discussion applies only to New Vista Class A Shares that are held as capital assets for U.S. federal income tax purposes (generally, property held for investment). This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to holders in light of their particular circumstances or status, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Sponsor or our directors and officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• financial institutions or financial services entities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• broker-dealers;

[**Table of Contents**](#TOC001)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• taxpayers that are subject to the mark-to-market method of accounting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax-exempt entities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• governments or agencies or instrumentalities thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• insurance companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulated investment companies or real estate investment trusts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expatriates or former long-term residents of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• persons that actually or constructively own five percent or more of our voting shares or five percent or more of the total value of all classes of our shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• persons that acquired New Vista Class A Shares pursuant to an exercise of employee share options or upon payout of a restricted share unit, in connection with employee share incentive plans or otherwise as compensation or in connection with the performance of services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• persons that hold New Vista Class A Shares as part of a straddle, constructive sale, hedging, conversion or other integrated or similar transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• persons whose functional currency is not the U.S. dollar;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• controlled foreign corporations; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• passive foreign investment companies.

This discussion is based on the Internal Revenue Code of 1986 (the "*Code*"), proposed, temporary and final Treasury Regulations promulgated under the Code, and judicial and administrative interpretations thereof, all as of the date hereof. All of the foregoing is subject to change, which change could apply retroactively and could affect the tax considerations described herein. This discussion does not address U.S. federal taxes other than those pertaining to U.S. federal income taxation (such as estate or gift taxes, the alternative minimum tax or the Medicare tax on net investment income), nor does it address any aspects of U.S. state or local or non-U.S. taxation.

We have not and do not intend to seek any rulings from the Internal Revenue Service (the "*IRS*") regarding the exercise of redemption rights. There can be no assurance that the IRS will not take positions inconsistent with the considerations discussed below or that any such positions would not be sustained by a court.

This discussion does not consider the tax treatment of partnerships or other pass-through entities or persons who hold our securities through such entities. If a partnership (or any entity or arrangement so characterized for U.S. federal income tax purposes) holds New Vista Class A Shares, the tax treatment of such partnership and a person treated as a partner of such partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships holding any New Vista Class A Shares and persons that are treated as partners of such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences of an exercise of redemption rights to them.

**EACH HOLDER SHOULD CONSULT ITS TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF AN EXERCISE OF REDEMPTION RIGHTS, INCLUDING THE EFFECTS OF U.S. FEDERAL, STATE AND LOCAL AND NON**-U**.S. TAX LAWS.**

As used herein, a "*U.S. Holder*" is a beneficial owner of New Vista Class A Shares who or that is, for U.S. federal income tax purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a citizen or individual resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a corporation (or other entity that is treated as a corporation for U.S. federal income tax purposes) that is created or organized (or treated as created or organized) in or under the laws of the United States or any state thereof or the District of Columbia;

[**Table of Contents**](#TOC001)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an estate whose income is subject to U.S. federal income tax regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a trust if (i) a U.S. court can exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (ii) it has a valid election in place to be treated as a U.S. person.

#### Redemption of New Vista Class A Shares
In addition to the PFIC considerations discussed below under "— *PFIC Considerations*," the U.S. federal income tax consequences of the redemption of a U.S. Holder's New Vista Class A Shares pursuant to an exercise of redemption rights will depend on whether the redemption qualifies as a sale of such shares redeemed under Section 302 of the Code or is treated as a distribution under Section 301 of the Code.

If the redemption qualifies as a sale of New Vista Class A Shares, a U.S. Holder will be treated as described below under the section entitled "— *U.S. Holders — Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of New Vista Class A Shares*." If the redemption does not qualify as a sale of New Vista Class A Shares, a U.S. Holder will be treated as receiving a distribution with the tax consequences described below under the section entitled "— *U.S. Holders — Taxation of Distributions*."

The redemption of New Vista Class A Shares will generally qualify as a sale of the New Vista Class A Shares that are redeemed if such redemption (i) is "substantially disproportionate" with respect to the redeeming U.S. Holder, (ii) results in a "complete termination" of such U.S. Holder's interest or (iii) is "not essentially equivalent to a dividend" with respect to such U.S. Holder. These tests are explained more fully below.

For purposes of such tests, a U.S. Holder takes into account not only ordinary shares actually owned by such U.S. Holder, but also ordinary shares that are constructively owned by such U.S. Holder. A redeeming U.S. Holder may constructively own, in addition to ordinary shares owned directly, ordinary shares owned by certain related individuals and entities in which such U.S. Holder has an interest or that have an interest in such U.S. Holder, as well as any ordinary shares such U.S. Holder has a right to acquire by exercise of an option, which would generally include shares which could be acquired pursuant to the exercise of the warrants.

The redemption of ordinary shares will generally be "substantially disproportionate" with respect to a redeeming U.S. Holder if the percentage of the respective entity's outstanding voting shares that such U.S. Holder actually or constructively owns immediately after the redemption is less than 80% of the percentage of the respective entity's outstanding voting shares that such U.S. Holder actually or constructively owned immediately before the redemption. Prior to an initial business combination, the New Vista Class A Shares may not be treated as voting shares for this purpose and, consequently, this substantially disproportionate test may not be applicable. There will be a complete termination of such U.S. Holder's interest if either (i) all of the ordinary shares actually or constructively owned by such U.S. Holder are redeemed or (ii) all of the ordinary shares actually owned by such U.S. Holder are redeemed and such U.S. Holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of ordinary shares owned by certain family members and such U.S. Holder does not constructively own any other ordinary shares. The redemption of New Vista Class A Shares will not be essentially equivalent to a dividend if it results in a "meaningful reduction" of such U.S. Holder's proportionate interest in the respective entity. Whether the redemption will result in a meaningful reduction in such U.S. Holder's proportionate interest will depend on the particular facts and circumstances applicable to it. The IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a "meaningful reduction."

If none of the foregoing tests is satisfied, then the redemption of New Vista Class A Shares will be treated as a distribution to the redeeming holder and the tax effects to such U.S. Holder will be as described below under the section entitled "— *Taxation of Distributions*." After the application of those rules, any remaining tax basis of the U.S. Holder in the redeemed New Vista Class A Shares will be added to such holder's adjusted tax basis in its remaining shares, or, if it has none, to such holder's adjusted tax basis in its warrants or possibly in other shares constructively owned by it.

U.S. Holders should consult their tax advisors as to the tax consequences of a redemption, including any special reporting requirements.

[**Table of Contents**](#TOC001)

*Taxation of Distributions.*

Subject to the PFIC rules discussed below under "— *PFIC Considerations*," if the redemption of a U.S. Holder's New Vista Class A Shares is treated as a distribution, as discussed above, such distribution will generally be treated as a dividend for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Such dividends will be taxable to a corporate U.S. Holder at regular rates and will not be eligible for the dividends-received deduction generally allowed to domestic corporations in respect of dividends received from other domestic corporations. With respect to non-corporate U.S. Holders, dividends will generally be taxed at preferential long-term capital gains rates only if (i) New Vista Class A Shares are readily tradable on an established securities market in the United States or (ii) New Vista Class A Shares are eligible for the benefits of an applicable income tax treaty, in each case provided that the Company is not treated as a PFIC in the taxable year in which the dividend was paid or in any previous year and certain holding period and other requirements are met. Because we believe it is likely that we were a PFIC for our prior taxable year ended December 31, 2022, it is likely that the lower applicable long-term capital gains rate would not apply to any redemption proceeds treated as a distribution. Moreover, it is unclear whether redemption rights with respect to the New Vista Class A Shares may prevent the holding period of such shares from commencing prior to the termination of such rights. U.S. Holders should consult their tax advisors regarding the availability of the lower rate for any redemption treated as a dividend with respect to New Vista Class A Shares.

Distributions in excess of our current and accumulated earnings and profits will generally constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. Holder's adjusted tax basis in the New Vista Class A Shares. Any remaining excess will be treated as gain realized on the sale or other disposition of the New Vista Class A Shares and will be treated as described below under the section entitled "— *Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of New Vista Class A Shares*."

*Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of New Vista Class A Shares.*

Subject to the PFIC rules discussed below under "— *PFIC Considerations*," if the redemption of a U.S. Holder's New Vista Class A Shares is treated as a sale or other taxable disposition, as discussed above, a U.S. Holder will generally recognize capital gain or loss in an amount equal to the difference between (i) the amount realized and (ii) the U.S. Holder's adjusted tax basis in the New Vista Class A Shares redeemed.

Under tax law currently in effect, long-term capital gains recognized by non-corporate U.S. Holders are generally subject to U.S. federal income tax at a reduced rate of tax. Capital gain or loss will constitute long-term capital gain or loss if the U.S. Holder's holding period for the ordinary shares exceeds one year at the time of disposition. However, it is unclear whether the redemption rights with respect to the New Vista Class A Shares described in this proxy statement may prevent the holding period of the New Vista Class A Shares from commencing prior to the termination of such rights. The deductibility of capital losses is subject to various limitations. U.S. Holders who hold different blocks of New Vista Class A Shares (New Vista Class A Shares purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

#### PFIC Considerations
A foreign corporation will be a passive foreign investment company ("*PFIC*") for U.S. federal income tax purposes if at least 75% of its gross income in a taxable year is passive income. Alternatively, a foreign corporation will be a PFIC if at least 50% of its assets in a taxable year of the foreign corporation, ordinarily determined based on fair market value and averaged quarterly over the year, are held for the production of, or produce, passive income. Passive income generally includes dividends, interest, rents and royalties (other than certain rents or royalties derived from the active conduct of a trade or business) and net gains from the disposition of passive assets.

We believe it is likely that we were a PFIC for our prior taxable year ended December 31, 2022. Our PFIC status for our current taxable year ending December 31, 2023, however, depends in part on whether we complete a business combination prior to the end of such year, as well as the timing and specifics of any such business combination. Because these and other facts on which any determination of PFIC status are based may not be known until the close of our current taxable year, there can be no assurances with respect to our PFIC status for such year. Even if we are not

[**Table of Contents**](#TOC001)

a PFIC for our current taxable year, a determination that we were a PFIC for any prior taxable year will continue to apply to any U.S. Holders who held New Vista Class A Shares during such prior taxable years, absent certain elections described below.

If we are determined to be a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder and the U.S. Holder did not make a timely and effective "qualified election fund" election (a "*QEF Election*") for each of our taxable years as a PFIC in which the U.S. Holder held New Vista Class A Shares, a QEF Election along with a purging election, or a "mark-to-market" election, then such holder will generally be subject to special rules (the "*Default PFIC Regime*") with respect to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any gain recognized by the U.S. Holder on the sale or other disposition of its New Vista Class A Shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any "excess distribution" made to the U.S. Holder (generally, any distributions to such U.S. Holder during a taxable year of the U.S. Holder that are greater than 125% of the average annual distributions received by such U.S. Holder in respect of its ordinary shares during the three preceding taxable years of such U.S. Holder or, if shorter, such U.S. Holder's holding period for such ordinary shares).

Under the Default PFIC Regime:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the U.S. Holder's gain or excess distribution will be allocated ratably over the U.S. Holder's holding period for its New Vista Class A Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount of gain allocated to the U.S. Holder's taxable year in which the U.S. Holder recognized the gain or received the excess distribution, or to the period in the U.S. Holder's holding period before the first day of the first taxable year in which we are a PFIC, will be taxed as ordinary income;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount of gain allocated to other taxable years (or portions thereof) of the U.S. Holder and included in such U.S. Holder's holding period will be taxed at the highest tax rate in effect for that year and applicable to the U.S. Holder; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an additional tax equal to the interest charge generally applicable to underpayments of tax will be imposed on the U.S. Holder in respect of the tax attributable to each such other taxable year of such U.S. Holder.

**THE PFIC RULES ARE VERY COMPLEX AND ARE IMPACTED BY VARIOUS FACTORS IN ADDITION TO THOSE DESCRIBED ABOVE. ALL U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE APPLICATION OF THE PFIC RULES TO THE REDEMPTION OF NEW VISTA CLASS A SHARES, INCLUDING, WITHOUT LIMITATION, WHETHER A QEF ELECTION, A PURGING ELECTION, A MARK**-TO-MARKET **ELECTION, OR ANY OTHER ELECTION IS AVAILABLE AND THE CONSEQUENCES TO THEM OF MAKING OR HAVING MADE ANY SUCH ELECTION, AND THE IMPACT OF ANY PROPOSED OR FINAL PFIC TREASURY REGULATIONS.**

#### Vote Required for Approval
Approval of the Extension Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals. If the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval

[**Table of Contents**](#TOC001)

of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023.

Additionally, unless the Redemption Limitation Amendment Proposal is approved, we will not proceed with the Extension if redemptions of our public shares would cause the Company to exceed the Redemption Limitation. However, in the event that the Redemption Limitation Amendment Proposal is not approved and we receive notice of redemptions of public shares approaching or in excess of the Redemption Limitation, we and/or our Sponsor may take action to increase our net tangible assets to avoid exceeding the Redemption Limitation.

The Sponsor and all of the Company's directors and officers are expected to vote all New Vista Shares owned by them in favor of the Extension Proposal. On the Record Date, the Sponsor and all of the Company's directors and officers beneficially owned and were entitled to vote an aggregate of 6,684,500 New Vista Class B Shares. See the section entitled "*Beneficial Ownership of Securities*" for additional information regarding the holders of New Vista Class B Shares and their respective ownership thereof.

In addition, subject to applicable securities laws (including with respect to material nonpublic information), the Sponsor, the Company's directors, officers or advisors or any of their respective affiliates may (i) purchase public shares from institutional and other investors (including those who vote, or indicate an intention to vote, against any of the proposals presented at the Extraordinary General Meeting, or elect to redeem, or indicate an intention to redeem, public shares), (ii) enter into transactions with such investors and others to provide them with incentives to not redeem their public shares, or (iii) execute agreements to purchase such public shares from such investors or enter into non-redemption agreements in the future. In the event that the Sponsor, the Company's directors, officers or advisors or any of their respective affiliates purchase public shares in situations in which the tender offer rules and restrictions on purchases would apply, they (a) would purchase the public shares at a price no higher than the price offered through the Company's redemption process (i.e., approximately $10.05 per share, based on the amounts held in the Trust Account as of September 30, 2022); (b) would represent in writing that such public shares will not be voted in favor of approving the Extension Proposal; and (c) would waive in writing any redemption rights with respect to the public shares so purchased.

Subject to the immediately preceding paragraph, the Sponsor and the Company's directors, officers or advisors, or any of their respective affiliates, may purchase public shares in privately negotiated transactions or in the open market prior to the Extraordinary General Meeting, although they are under no obligation to do so. Any such purchases that are completed after the Record Date may include an agreement with a selling shareholder that such shareholder, for so long as it remains the record holder of the New Vista Shares in question, will vote in favor of the proposals and/or will not exercise its redemption rights with respect to the New Vista Shares so purchased. The purpose of such share purchases and other transactions would be to increase the likelihood that the proposals to be voted upon at the Extraordinary General Meeting are approved by the requisite number of votes. In the event that such purchases do occur, the purchasers may seek to purchase shares from shareholders who would otherwise have voted against the proposals and elected to redeem their shares for a portion of the Trust Account. Any such privately negotiated purchases may be effected at purchase prices that are below or in excess of the per-share pro rata portion of the Trust Account. Any public shares held by or subsequently purchased by our affiliates may be voted in favor of the proposals. None of the Sponsor or the Company's directors, officers or advisors or any of their respective affiliates may make any such purchases when they are in possession of any material nonpublic information not disclosed to the seller or during a restricted period under Regulation M under the Exchange Act.

#### Interests of the Sponsor and the Company's Directors and Officers
When you consider the recommendation of the Board, you should keep in mind that the Sponsor and the Company's officers and directors have interests that may be different from, or in addition to, your interests as a shareholder. These interests include, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, the 6,900,000 aggregate New Vista Class B Shares held by the Sponsor and certain of our directors will be worthless (as the Sponsor and such directors have waived liquidation rights with respect to such shares), as will the 5,680,000 private placement warrants held by the Sponsor;

[**Table of Contents**](#TOC001)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in connection with the IPO, the Sponsor agreed that it will be liable under certain circumstances to ensure that the proceeds in the Trust Account are not reduced by the claims of any third party for services rendered or products sold to the Company or prospective target businesses with which the Company has entered into certain agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all rights specified in the Charter relating to the right of officers and directors to be indemnified by the Company, and of the Company's officers and directors to be exculpated from monetary liability with respect to prior acts or omissions, will continue after an initial Business Combination and, if the Extension Proposal is not approved and no initial Business Combination is completed by February 19, 2023, so that the Company liquidates, the Company will not be able to perform its obligations to its officers and directors under those provisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• none of the Company's officers or directors has received any cash compensation for services rendered to the Company, and all of the current officers and directors are expected to continue to serve in their roles at least through the date of the Extraordinary General Meeting and may continue to serve following any potential initial Business Combination and receive compensation thereafter; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Sponsor and the Company's officers and directors and their respective affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them related to identifying, investigating, negotiating and completing an initial Business Combination and, if the Extension Proposal is not approved or not implemented and we do not consummate an initial Business Combination by February 19, 2023, they will not have any claim against the Trust Account for reimbursement so that the Company will most likely be unable to reimburse such expenses.

#### The Sponsor
The Company's sponsor is New Vista Acquisition Sponsor LLC, a Delaware limited liability company. The Sponsor currently owns 6,684,500 New Vista Class B Shares and is controlled by its managing members — Dennis A. Muilenburg, Kirsten Bartok Touw and Travis S. Nelson. Each of Mr. Muilenburg, Ms. Bartok Touw and Mr. Nelson are U.S. persons. Each of Mr. Muilenburg, Ms. Bartok Touw and Mr. Nelson may be deemed to beneficially own shares held by our Sponsor by virtue of their shared control over our Sponsor.

Subject to the other parties involved in our initial Business Combination, the Company does not believe that any of the above facts or relationships regarding the Sponsor would, by themselves, subject our initial Business Combination to regulatory review, including review by CFIUS, nor does the Company believe that if such a review were conceivable that, based solely on such facts or relationships, such Business Combination ultimately would be prohibited.

However, if our initial Business Combination were to become subject to regulatory review and approval requirements, including pursuant to foreign investment regulations and review by governmental entities such as CFIUS, such Business Combination may be delayed or ultimately prohibited. For more information, see the section entitled "*Risk Factor — Our initial Business Combination may be delayed or ultimately prohibited if such initial Business Combination is subject to regulatory review and approval requirements, including pursuant to foreign investment regulations and review by governmental entities such as CFIUS*."

**Changes in laws or regulations or how such laws or regulations are interpreted or applied, or a failure to comply with any laws or regulations, may adversely affect our business, including our ability to negotiate and complete our initial Business Combination, and results of operations.**

We are and will be subject to laws and regulations enacted by national, regional and local governments and, potentially, foreign jurisdictions. In particular, we will be required to comply with certain SEC and other legal requirements, an initial Business Combination may be contingent on our ability to comply with certain laws and regulations and the post-closing combined may be subject to additional laws and regulations. Compliance with, and monitoring of, applicable laws and regulations may be difficult, time consuming and costly. Those laws and regulations and their interpretation and application may also change from time to time, including as a result of changes in economic, political, social and government policies, and those changes could have a material adverse effect on our business, including our ability to negotiate and complete our initial Business Combination, and results of operations.

[**Table of Contents**](#TOC001)

In addition, a failure to comply with applicable laws or regulations, as interpreted and applied, could have a material adverse effect on our business, including our ability to negotiate and complete our initial Business Combination, and results of operations.

On March 30, 2022, the SEC issued the SPAC Rule Proposals relating to, among other items, enhancing disclosures in business combination transactions involving SPACs and private operating companies; amending the financial statement requirements applicable to transactions involving shell companies; effectively limiting the use of projections in SEC filings in connection with proposed business combination transactions; increasing the potential liability of certain participants in proposed business combination transactions; and the extent to which SPACs could become subject to regulation under the Investment Company Act. These rules, if adopted, whether in the form proposed or in revised form, may materially adversely affect our ability to complete an initial Business Combination.

**If we are deemed to be an investment company under the Investment Company Act, we would be required to institute burdensome compliance requirements and our activities would be severely restricted. As a result, in such circumstances, we would expect to abandon our efforts to complete an initial Business Combination and liquidate the Trust Account.**

If we are deemed to be an investment company under the Investment Company Act, our activities would be severely restricted, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrictions on the nature of our investments; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrictions on the issuance of securities.

In addition, we would be subject to burdensome compliance requirements, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• registration as an investment company with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adoption of a specific form of corporate structure; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reporting, record keeping, voting, proxy and disclosure requirements and other rules and regulations that we are currently not subject to.

As a result, if we were deemed to be an investment company under the Investment Company Act, we would expect to abandon our efforts to complete an initial Business Combination and liquidate the Trust Account.

In order not to be regulated as an investment company under the Investment Company Act, unless we can qualify for an exclusion, we must ensure that we are engaged primarily in a business other than investing, reinvesting or trading in securities and that our activities do not include investing, reinvesting, owning, holding or trading "investment securities" constituting more than 40% of our total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. Our business will be to identify and complete an initial Business Combination and thereafter to operate the post-transaction business or assets for the long term. We do not plan to buy businesses or assets with a view to resale or profit from their resale. We do not plan to buy unrelated businesses or assets or to be a passive investor.

To that end, the proceeds held in the Trust Account may only be invested in United States "government securities" within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Pursuant to our Investment Management Trust Agreement, the trustee is not permitted to invest in other securities or assets. By restricting the investment of the proceeds to these instruments, and by having a business plan targeted at acquiring and growing businesses for the long term, we intend to avoid being deemed an "investment company" within the meaning of the Investment Company Act.

The SPAC Rule Proposals (as defined above) under the Investment Company Act would provide a safe harbor for SPACs from the definition of "investment company" under Section 3(a)(1)(A) of the Investment Company Act, provided that they satisfy certain conditions that limit a SPAC's duration, asset composition, business purpose and activities. The duration component of the proposed safe harbor rule would require a SPAC to file a Current Report on Form 8-K with the SEC announcing that it has entered into an agreement with the target company (or companies) to engage in an initial Business Combination no later than 18 months after the effective date of the SPAC's registration statement for its initial public offering. The SPAC would then be required to complete its initial Business Combination no later than 24 months after the effective date of its registration statement for its initial public offering. Although the

[**Table of Contents**](#TOC001)

SPAC Rule Proposals, including the proposed safe harbor rule, have not yet been adopted, and may be adopted in a revised form, the SEC has indicated that there are serious questions concerning the applicability of the Investment Company Act to a SPAC that does not complete its initial Business Combination within the proposed time frame set forth in the proposed safe harbor rule.

Notwithstanding whether or not the SPAC Rule Proposals are adopted by the SEC, we may be deemed to be an investment company under the Investment Company Act. As a SPAC, we were formed for the sole purpose of completing an initial Business Combination by February 19, 2023 (i.e. 24 months from the closing of our IPO). The longer that the funds in the Trust Account are held in short-term U.S. government treasury obligations or in money market funds invested exclusively in such securities, the greater the risk that we may be considered an unregistered investment company. Accordingly, we may determine, in our discretion, to liquidate the securities held in the Trust Account at any time, and instead hold all funds in the Trust Account in cash, which would reduce or eliminate the accrual of interest in the Trust Account and thereby reduce what our public shareholders would receive upon any redemption or liquidation. Further, if we do not invest the proceeds held in the Trust Account as discussed above, we may be deemed to be subject to the Investment Company Act, and the loss you may suffer as a result of being deemed subject to the Investment Company Act may be greater than if we liquidated the securities held in the Trust Account and instead held such funds in cash.

We do not believe that our principal activities will subject us to regulation under the Investment Company Act. However, if we were deemed to be subject to the Investment Company Act, compliance with these additional regulatory burdens would require additional expenses for which we have not allotted funds and may hinder our ability to complete an initial Business Combination. In such circumstances, we would expect to abandon our efforts to complete an initial Business Combination and liquidate the Trust Account. If we are unable to complete our initial Business Combination within the required time period and are required to liquidate the Trust Account, our public shareholders may receive only approximately $10.05 per share (based on the amount in the Trust Account as of September 30, 2022), or less in certain circumstances, on the liquidation of our Trust Account, and our warrants will expire worthless. If we are required to liquidate, you may lose all or part of your investment in the Company and you will not be able to realize any future appreciation in the value of your investment since an initial Business Combination would not have been consummated.

**In order to mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act, we may, at any time, instruct the trustee to hold all funds in the Trust Account in cash until the earlier of the consummation of an initial Business Combination or our liquidation. Any decision to hold all funds in the Trust Account in cash would likely reduce the amount our public shareholders would receive upon any redemption or liquidation.**

While the funds in our Trust Account may only be invested in U.S. government treasury bills with a maturity of 185 days or less, or in money market funds investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 under the Investment Company Act, the Company may, at any time, instruct the trustee to hold all funds in the Trust Account in cash until the earlier of the consummation of an initial Business Combination or our liquidation in order to mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act. Any decision to hold all funds in the Trust Account in cash, combined with any permitted withdrawals of interest held in the Trust Account to pay our taxes, would likely reduce the effective yield on the amounts in the Trust Account and the amount our public shareholders would receive upon any redemption or liquidation.

#### Recommendation
As discussed above, after careful consideration of all relevant factors, the Board has determined that the Extension Proposal is in the best interests of the Company and its shareholders. The Board has approved and declared advisable the adoption of the Extension Proposal.

**OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE EXTENSION PROPOSAL. OUR BOARD EXPRESSES NO OPINION AS TO WHETHER YOU SHOULD REDEEM YOUR PUBLIC SHARES.**

[**Table of Contents**](#TOC001)

#### PROPOSAL NO. 2 — THE Redemption limitation amendment PROPOSAL

#### Background
Section 49.2 of the Company's Charter provides the following:

"Prior to the consummation of a Business Combination, the Company shall either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) submit such Business Combination to its Members for approval; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) provide Members with the opportunity to have their Shares repurchased by means of a tender offer for a per-Share repurchase price payable in cash, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two business days prior to the consummation of such Business Combination, including interest earned on the Trust Account (net of taxes paid or payable, if any), *divided* by the number of then issued Public Shares, provided that the Company shall not repurchase Public Shares in an amount that would cause the Company's net tangible assets to be less than US$5,000,001 following such repurchases. Such obligation to repurchase Shares is subject to the completion of the proposed Business Combination to which it relates."

Section 49.4 of the Company's Charter provides the following:

"At a general meeting called for the purposes of approving a Business Combination pursuant to this Article, in the event that such Business Combination is approved by Ordinary Resolution, the Company shall be authorised to consummate such Business Combination, provided that the Company shall not consummate such Business Combination unless the Company has net tangible assets of at least US$5,000,001 immediately prior to, or upon such consummation of, or any greater net tangible asset or cash requirement that may be contained in the agreement relating to, such Business Combination."

Section 49.5 of the Company's Charter provides the following:

"Any Member holding Public Shares who is not the Sponsor, a Founder, Officer or Director may, at least two business days' prior to any vote on a Business Combination, elect to have their Public Shares redeemed for cash, in accordance with any applicable requirements provided for in the related proxy materials (the "**IPO Redemption**"), provided that no such Member acting together with any Affiliate of his or any other person with whom he is acting in concert or as a partnership, limited partnership, syndicate, or other group for the purposes of acquiring, holding, or disposing of Shares may exercise this redemption right with respect to more than 15 per cent of the Public Shares in the aggregate without the prior consent of the Company and provided further that any beneficial holder of Public Shares on whose behalf a redemption right is being exercised must identify itself to the Company in connection with any redemption election in order to validly redeem such Public Shares. If so demanded, the Company shall pay any such redeeming Member, regardless of whether he is voting for or against such proposed Business Combination, or at all, a per-Share redemption price payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the Business Combination, including interest earned on the Trust Account (such interest shall be net of taxes payable) and not previously released to the Company to pay its taxes, *divided* by the number of then issued Public Shares (such redemption price being referred to herein as the "**Redemption Price**"), but only in the event that the applicable proposed Business Combination is approved and consummated. The Company shall not redeem Public Shares that would cause the Company's net tangible assets to be less than US$5,000,001 following such redemptions (the "**Redemption Limitation**")."

Section 49.8 of the Company's Charter provides the following:

"In the event that any amendment is made to the Articles:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) to modify the substance or timing of the Company's obligation to allow redemption in connection with a Business Combination or redeem 100 per cent of the Public Shares if the Company does not consummate a Business Combination within 24 months from the consummation of the IPO, or such later time as the Members may approve in accordance with the Articles; or

[**Table of Contents**](#TOC001)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) with respect to any other provision relating to Members' rights or pre-Business Combination activity, each holder of Public Shares who is not the Sponsor, a Founder, Officer or Director shall be provided with the opportunity to redeem their Public Shares upon the approval or effectiveness of any such amendment at a per-Share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, divided by the number of then issued and outstanding Public Shares. The Company's ability to provide such redemption in this Article is subject to the Redemption Limitation."

The purpose of the Redemption Limitation requirements (set forth in the text above) was to ensure that the Company will not be subject to the "penny stock" rules of the SEC as long as it met the Redemption Limitation requirement, and therefore not be deemed a "blank check company" as defined under Rule 419 of the Securities Act because it complied with Rule 3a51-1(g)(1) (the "*NTA Rule*"). The Company is proposing to amend its Charter to remove the Redemption Limitation requirements underlined above. The NTA Rule is one of several exclusions from the "penny stock" rules of the SEC and the Company believes that it can rely on another exclusion, which relates to it being listed on the Nasdaq Capital Market (Rule 3a51-1(a)(2)) (the "*Exchange Rule*"). Therefore, the Company intends to rely on the exclusion from the penny stock rules set forth in Rule 3a51-1(a)(2) as a result of its securities being listed on the Nasdaq Capital Market.

#### Rule 419 blank check companies and "penny stock" Issuers
As disclosed in our IPO prospectus, because the net proceeds of the our IPO were being used to complete an initial Business Combination with a target business that had not been selected at the time of the IPO, the Company may be deemed a "blank check company". Under Rule 419 of the Securities Act the term "blank check company" means a company that (i) is a development stage company that has no specific business plan or purpose or has indicated that its business plan is to engage in a merger or acquisition with an unidentified company or companies, or other entity or person; and (ii) is issuing "penny stock," as defined in Rule 3a51-1 under the Exchange Act. Rule 3a51-1 sets forth that that term "penny stock" shall mean any equity security, unless it fits within certain enumerated exclusions including the NTA Rule and the Exchange Rule. Historically SPACs have relied upon the NTA Rule to avoid being deemed a penny stock issuer. The inclusion of the language in the sections of the Charter as reproduced above, was to ensure that through the consummation of an initial Business Combination, the Company would not be considered a penny stock issuer and therefore a blank check company if no other exemption from the rule was available.

#### Reliance on Rule 3a51-1(a)(2)
The Exchange Rule excludes from the definition of "penny stock" a security that is registered, or approved for registration upon notice of issuance, on a national securities exchange, or is listed, or approved for listing upon notice of issuance on, an automated quotation system sponsored by a registered national securities association, that has established initial listing standards that meet or exceed the criteria in the rule. The Company's securities are listed on the Nasdaq Capital Market and have been since the consummation of its IPO. The Company believes that the Nasdaq Capital Market has initial listing standards that meet the criteria identified in the Exchange Rule and that it can therefore rely on this rule to avoid being treated as a penny stock. Therefore, the inclusion of the Redemption Limitation is unnecessary.

#### Reasons for the Redemption Limitation Amendment
Shareholders are being asked to adopt the proposed Redemption Limitation Amendment Proposal to the Charter which, in the judgment of the Board, may facilitate the consummation of an initial Business Combination. The Charter limits the Company's ability to consummate an initial Business Combination, or to redeem public shares in connection with an initial Business Combination, if it would cause the Company to have less than $5,000,001 in net tangible assets. The purpose of such limitation was initially to ensure that the public shares were not deemed to be "penny stocks" pursuant to Rule 3a51-1 under the Exchange Act in the event that such public shares failed to be listed on an approved national securities exchange. If the Redemption Limitation Amendment Proposal is not approved or not implemented and there are significant requests for redemption such that the Company's net tangible assets would be less than $5,000,001 upon the consummation of an initial Business Combination, the Charter would prevent the

[**Table of Contents**](#TOC001)

Company from being able to consummate an initial Business Combination even if all other conditions to closing are met. If the Redemption Limitation Amendment Proposal is approved and implemented, the Charter would be amended to delete the Redemption Limitation language from the Charter as set forth in <u>Annex A</u> to this proxy statement.

The Charter also entitles shareholders of the Company to redemption rights if the Company seeks to amend the Charter to extend the period of time to complete an initial Business Combination or makes certain other changes to provisions governing pre-initial Business Combination activity. Redemption rights are limited, however, and any such amendment would be voided if the net tangible assets redemption limit cannot be satisfied. As discussed above, the Company believes that the net tangible assets limitation may be removed from the Charter. The proposed amendments in <u>Annex A</u> to this proxy statement would remove this limitation with respect to redemption rights in connection with Charter amendments as well.

#### The Redemption Limitation Amendment
We are proposing to amend the Charter pursuant to the second resolution in the form set forth in <u>Annex A</u> of this proxy statement to eliminate from the Charter the Redemption Limitation in order to allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation.

#### Reasons for the Redemption Limitation Amendment Proposal
The Board believes it is in the best interests of the Company and its shareholders for the Company to be allowed to effect any redemptions in connection with the Extraordinary General Meeting irrespective of whether such redemptions would exceed the Redemption Limitation.

#### If the Redemption Limitation Amendment Proposal Is Approved
If the Redemption Limitation Amendment Proposal is approved and implemented (and the Extension Proposal is also approved and implemented), we plan to file the Redemption Limitation Amendment with the Cayman Registrar pursuant to second resolution as set forth in <u>Annex A</u> of this proxy statement and, assuming the Extension Proposal is approved and is implemented, redeem public shares as necessary, irrespective of whether such redemptions exceed the Redemption Limitation. However, notwithstanding the approval of the Charter Amendment Proposals, our Board may decide to abandon the Charter Amendment Proposals and the Trust Amendment Proposal at any time and for any reason prior to the effectiveness of the filing with the Cayman Registrar. Assuming the Extension Proposal is approved, if our Board abandons the Redemption Limitation Amendment, public shareholders will not have their public shares redeemed if the Redemption Limitation is exceeded. If our Board abandons all of the Charter Amendment Proposals, public shareholders will not be entitled to exercise redemption rights.

#### If the Redemption Limitation Amendment Proposal Is Not Approved or Not Implemented
If the Redemption Limitation Amendment Proposal is not approved or not implemented, we will not redeem public shares to the extent that accepting all properly submitted redemption requests would exceed the Redemption Limitation. In the event that the Redemption Limitation Amendment Proposal is not approved or not implemented and we receive notice of redemptions of public shares approaching or in excess of the Redemption Limitation, we and/or the Sponsor may take action to increase our net tangible assets to avoid the Redemption Limitation, which may include, at our and our Sponsor's option and in our and its sole discretion, any, several or all of the following actions: (a) attempting to secure waivers of certain of our significant liabilities, including the deferred underwriting fees and (b) entering into non-redemption agreements with certain of our significant shareholders. If the Redemption Limitation Amendment Proposal is not approved or not implemented and the Redemption Limitation is exceeded, either because we do not take action to increase our net tangible assets or because our attempt to do so is not successful, then we will not proceed with the amendments set forth in <u>Annex A</u> of the accompanying proxy statement and we will not redeem any public shares. In such case, public shares which a public shareholder elects to redeem but which are not redeemed shall be returned to such public shareholder or such public shareholder's account and such public shareholder will retain the right to have their public shares redeemed for cash if the Company has not completed an initial Business Combination by February 19, 2023.

[**Table of Contents**](#TOC001)

#### Vote Required for Approval
Approval of the Redemption Limitation Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of at least two-thirds of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so at the Extraordinary General Meeting. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals. We believe each of the Proposals constitutes a "non-discretionary" matter, and therefore, there will not be any broker non-votes at the Extraordinary General Meeting.

#### Recommendation
As discussed above, after careful consideration of all relevant factors, our Board has determined that the Redemption Limitation Amendment Proposal is in the best interests of the Company and its shareholders. Our Board has approved and declared advisable the Redemption Limitation Amendment.

[**Table of Contents**](#TOC001)

#### PROPOSAL NO. 3 — THE LIQUIDATION AMENDMENT PROPOSAL

#### Overview
The proposed Liquidation Amendment would amend the Company's Charter to permit our Board, in its sole discretion, to elect to wind up our operations on an earlier date than the Extension Date (including prior to the current termination date) as determined by our Board and included in a public announcement. The complete text of the proposed amendment is attached to this proxy statement as Annex A. All shareholders are encouraged to read the proposed amendment in its entirety for a more complete description of its terms.

#### Reasons for the Proposed Liquidation Amendment
The Company is proposing to amend its Charter to permit our Board to elect to wind up our operations on an earlier date and liquidate the Trust Account following effectiveness of the amended Charter and prior to February 19, 2024 (including a date prior to the current termination date) if it determines such action is in the best interests of shareholders. In electing to wind up at an earlier date, the Board may take into account various factors, including, but not limited to, the prospect of identifying a target and negotiating and consummating a business combination prior to the end of the Extension Period.

The purpose of the Liquidation Amendment Proposal is to amend our Charter to enable the Board, in its sole discretion, to liquidate the Trust Account and dissolve in accordance with law and to redeem all of the New Vista Class A Shares included as part of the units sold in the Company's IPO prior to the scheduled end of the Extension Period (including a date prior to the current termination date), after taking into account various factors, including, but not limited to, the prospect of identifying a target and negotiating and consummating a business combination prior to the end of the Extension Period. Accordingly, the Board believes that it is in the best interests of our shareholders to provide additional flexibility to wind up our operations, in which case we will liquidate the Trust Account and dissolve in accordance with law and to redeem all public shares. If a suitable business combination is timely identified, the Company intends to hold another shareholders' meeting prior to the expiration of the Extension Period in order to seek shareholder approval of a potential business combination.

#### If the Liquidation Amendment Proposal Is Approved
If the Liquidation Amendment Proposal, as well as the Extension Amendment Proposal and the Trust Amendment Proposal, are approved, these Amendments in the form of Annex A hereto will, upon with the Cayman Registrar, be effective and the Trust Account will not be disbursed except in connection with our completion of the initial business combination or in connection with our liquidation if we do not complete the initial business combination by the applicable termination date. The Company will then continue to attempt to identify and consummate an initial business combination until the applicable Extension Period or until the Company's Board determines, in its sole discretion, that it will not be able to consummate the initial business combination before the expiration of the Extension Period and does not wish to seek an additional extension.

#### If the Liquidation Amendment Proposal Is Not Approved
If the Liquidation Amendment Proposal, the Extension Amendment Proposal or the Trust Amendment Proposal are not approved and we have not consummated the initial business combination by February 19, 2023, we will we will (i) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

#### PROPOSAL NO. 4 — THE TRUST AMENDMENT PROPOSAL

#### Overview
The proposed Trust Amendment would amend the Trust Agreement to allow the Company to extend the date by which the Company would be required to consummate a business combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion. A copy of the proposed Trust Amendment is attached to this proxy statement as Annex B. All shareholders are encouraged to read the proposed amendment in its entirety for a more complete description of its terms.

#### Reasons for the Trust Amendment
The purpose of the Trust Amendment is to allow the Company to extend the date by which the Company would be required to consummate a business combination from February 19, 2023 to February 19, 2024, or such earlier date as determined by our Board in its sole discretion. The Trust Amendment parallels the Charter Amendment Proposals.

The Company's current Trust Agreement provides that the Company has until 24 months after the closing of the IPO, and such later day as may be approved by the Company's shareholders in accordance with the Company's Charter to terminate the Trust Agreement and liquidate the Trust Account.

#### If the Trust Amendment Is Approved
If both the Charter Amendment Proposals and the Trust Amendment Proposal are approved and implemented, the amendment to the Trust Agreement in the form of Annex B hereto will be executed and the Trust Account will not be disbursed except in connection with our completion of the initial business combination or in connection with our liquidation if we do not complete the initial business combination by the applicable termination date. The Company will then continue to attempt to identify and consummate an initial business combination until the applicable Extension Period or until the Company's Board determines in its sole discretion that it will not be able to consummate the initial business combination by the applicable Extension Period and does not wish to continue operations until such expiration.

#### If the Trust Amendment Is Not Approved
If the Trust Amendment is not approved and we do not consummate the initial business combination by February 19, 2023, we will (a) cease all operations except for the purpose of winding up; (b) as promptly as reasonably possible, but not more than ten (10) business days thereafter, redeem our public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (*less* up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), *divided by* the number of then issued and outstanding public shares, which redemption will completely extinguish public shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any); and (c) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and the Board, liquidate and dissolve, subject, in each case, to New Vista's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless if we fail to complete our initial Business Combination by February 19, 2023, or, if the Extension Proposal is approved, the Extended Date.

#### Vote Required for Approval
Approval of the Trust Amendment Proposal requires the affirmative vote of 65% of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who do so in person or by proxy at the Extraordinary General Meeting.

Public shareholders may elect to redeem their public shares regardless of whether or how they vote on the Trust Amendment Proposal at the Meeting; however, redemption payments for Elections in connection with this Meeting will only be made if the Charter Amendment Proposals and the Trust Amendment Proposal receive the requisite shareholder approvals and we determine to implement the Charter Amendments and Trust Amendment.

#### PROPOSAL NO. 5 — THE ADJOURNMENT PROPOSAL

#### Overview
The Adjournment Proposal, if adopted, will allow our Board to adjourn the Extraordinary General Meeting to a later date or dates to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of any of the Charter Amendment Proposals. The Adjournment Proposal will only be presented at the Extraordinary General Meeting if, based on the tabulated votes, there are not sufficient votes at the time of the Extraordinary General Meeting to approve any of the Charter Amendment Proposals.

#### Consequences if the Adjournment Proposal is Not Approved
If the Adjournment Proposal is not approved by our shareholders, our Board may not be able to adjourn the Extraordinary General Meeting to a later date in the event that there are insufficient votes for, or otherwise in connection with, the approval of any of the Charter Amendment Proposals.

#### Vote Required for Approval
The Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of the New Vista Shares issued and outstanding, represented in person or by proxy and entitled to vote thereon and who vote at the Extraordinary General Meeting. Abstentions and broker non-votes will be counted in connection with the determination of whether a valid quorum is established but will have no effect on any of the proposals.

#### Resolution to be Voted Upon
The full text of the resolution to be proposed is as follows:

"**RESOLVED**, as an ordinary resolution, that the adjournment of the extraordinary general meeting to a later date or dates to be determined by the chairman of the extraordinary general meeting, if necessary, to permit further solicitation and vote of proxies be confirmed, ratified and approved in all respects."

#### Recommendation of the Board
As discussed above, after careful consideration of all relevant factors, our Board has determined that the Adjournment Proposal is in the best interests of the Company and its shareholders. Therefore, if there are insufficient votes for, or otherwise in connection with, the approval of any of the Charter Amendment Proposals, our Board will approve and declare advisable adoption of the Adjournment Proposal.

#### BENEFICIAL OWNERSHIP OF SECURITIES
The following table sets forth information regarding the beneficial ownership of New Vista Shares as of January 10, 2023, based on information obtained from the persons named below, with respect to the beneficial ownership of New Vista Shares, by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) each person known by New Vista to be the beneficial owner of more than five percent (5%) of its issued and outstanding New Vista Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) each of New Vista's executive officers and directors that beneficially owns New Vista Shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) all of New Vista's executive officers and directors, as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or will become exercisable within 60 days. Except as described in the footnotes below and subject to applicable community property laws and similar laws, we believe that each person listed below has sole voting and investment power with respect to such shares.

In the table below, percentage ownership is based on 34,500,000 New Vista Shares outstanding as of January 10, 2023, including (a) 27,600,000 New Vista Class A Shares and (b) 6,900,000 New Vista Class B Shares. Voting power represents the combined voting power of New Vista Shares owned beneficially by such person. On all matters to be voted upon, the holders of the New Vista Shares vote together as a single class. The table below does not include any New Vista Shares underlying our outstanding warrants because such securities are not exercisable within 60 days of January 10, 2023.

#### OTHER MATTERS

#### Shareholder Proposals
No business may be transacted at an extraordinary general meeting other than business that is either (i) specified in the notice of the extraordinary general meeting (or any supplement thereto) given by or at the direction of the directors of the Company or (ii) otherwise properly brought before the extraordinary general meeting in accordance with the requirements set forth in the Charter of the Company.

#### Delinquent Section 16(a) Reports
Section 16(a) of the Exchange Act requires our officers, directors and persons who beneficially own more than ten percent of our public shares to file reports of ownership and changes in ownership with the SEC. These reporting persons are also required to furnish us with copies of all Section 16(a) forms they file. Based solely upon a review of such forms furnished since the effective date of our IPO, we believe that there have been no delinquent filers other than as previously disclosed in the Company's SEC filings.

#### Fiscal Year 2021 Annual Report and SEC Filings
Our financial statements for the year ended December 31, 2021, are included in our Annual Report on Form 10-K, filed with the SEC on March 31, 2022. This proxy statement, our Annual Report, and our Quarterly Reports on Form 10-Q for each of the quarterly periods ended March 31, 2022, June 30, 2022, and September 30, 2022, are available from the SEC at its website at *www.sec.gov*. You may also obtain a copy of our Annual Report without charge by sending a written request to New Vista Acquisition Corp, 125 South Wacker Drive, Suite 300, Chicago, IL 60606.

#### DELIVERY OF DOCUMENTS TO SHAREHOLDERS
For shareholders receiving printed proxy materials, unless we have received contrary instructions, we may send a single copy of this proxy statement to any household at which two (2) or more shareholders reside if we believe the shareholders are members of the same family. This process, known as "householding," reduces the volume of duplicate information received at any one (1) household and helps to reduce our expenses. However, if shareholders prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, the shareholders should follow the instructions described below. Similarly, if an address is shared with another shareholder and together both of the shareholders would like to receive only a single set of our disclosure documents, the shareholders should follow these instructions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the shares are registered in the name of the shareholder, the shareholder should contact us at our offices at 125 South Wacker Drive, Suite 300, Chicago, IL 60606, or (312) 855-2083, to inform us of their request; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if a bank, broker or other nominee holds the shares, the shareholder should contact the bank, broker or other nominee directly.

Pursuant to Section 1(i) of the Investment Management Trust Agreement between New Vista Acquisition Corp (the "***Company***") and Continental Stock Transfer & Trust Company (the "***Trustee***"), dated as of February 16, 2021 (as amended, the "***Trust Agreement***"), this is to advise you that the Company did not effect a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with a target business (the "***Business Combination***") within the time frame specified in the Company's amended and restated memorandum and articles of association, as described in the Company's Prospectus relating to the Offering.
