The following is a transcript of a recorded question and answer segment by Manuel Chavez, CEO of Mobile Infrastructure Corporation (“MIC”) and Stephanie Hogue, President and CFO of MIC, as it relates to the proposed business combination of Fifth Wall Acquisition Corp. III and MIC and first made publicly available on July 24, 2023.

Question on screen: What is the current status of the transaction?

00;00;05;14 - 00;00;15;21

Stephanie Hogue

We are working towards a close this summer. A key date is the special meeting of MIC Common Stockholders on August 10th, 2023 at 9 a.m. Eastern time.

00;00;15;21 - 00;00;48;26

Stephanie Hogue

We will, among other things, hold a vote to approve the transaction. When the merger closes, your shares of common stock are expected to be publicly listed on the New York Stock Exchange under the ticker beep. After this time, shares of common stock will be able to be traded freely. Your vote is very important. No matter how many shares of MIC common stock you own, this merger cannot be completed without the approval from MIC Common stock shareholders.

The record date for determining the stockholders entitled to vote on the transaction is June 15th, 2023, by the close of business.

Question on screen: Why should I vote for this transaction?

00;00;49;21 - 00;01;49;05

Stephanie Hogue

Your vote is very important.

You must vote yes to ensure we get to the next step in this process. The completion of the merger is expected to give you liquidity on the New York Stock Exchange or the NYSE American Exchange, meaning that you’ll be able to sell your shares on the open market.

Your shares of common stock of Mobile Infrastructure Corporation will be exchanged for common stock of the combined company, which will be freely tradable following the closing of the merger.

Importantly, insider shareholders and management will be subject to a lock-up period on the shares that they own. We think this is crucial to align interest as we continue to grow the platform.

The public listing of mobile infrastructure stock would mark an important step in our path towards creating a next generation publicly listed parking platform.

We believe that there is tremendous value to unlock as we continue to execute on our strategy and reap the benefits from our active asset management initiatives. We have an exciting opportunity in terms of our existing portfolio as well as the opportunity for additional growth through acquisition over time.

Question on screen: What do I need to do as a shareholder?

00;01;49;28 - 00;02;03;22

Stephanie Hogue

This is a very important question. Getting to the next step in this process relies on you voting “yes”. You should have received a proxy statement which was mailed on July 11th and provides instructions on how you can cast your “yes” vote today.

00;02;05;03 - 00;02;31;05

Manuel Chavez

Well, assuming that you and your fellow shareholders vote yes to approve the merger, every one share of MIC common stock you hold will convert to 1.5 shares of the new BEEP stock. This applies to each share of MIC common stock held prior to the effective time of the merger. Holders of MIC’s preferred stock will receive one share of preferred stock of the surviving company for each share of MIC preferred stock held prior to the effective time of the merger.

Question on screen: At what price will my shares list?

00;02;32;24 - 00;02;44;21

Manuel Chavez

Your shares of BEEP stock will list at $10 per share. But again, it’s important to note that you will receive 1.5 shares of BEEP stock for each share of MIC stock you own.

Question on screen: Are you going to be paying a dividend?

00;02;45;05 - 00;03;06;28

Manuel Chavez

Dividends on Mobile Infrastructure Corp. Series A convertible redeemable preferred stock and Series one convertible Redeemable Preferred stock are continuing to accrue in accordance with the terms. The exact timing of the payment has not yet been set.

Similarly, the company has not yet made a determination whether dividends will be paid on the common stock.

Question on screen: Why is being a publicly listed company good for Mobile Infrastructure (why should we remain shareholders)?

00;03;10;03 - 00;04;00;09

Manuel Chavez

Parking is an attractive asset class with relatively stable cash flows, high contribution margin and low labor cost, low recurring capital requirement, and

we believe mobile infrastructure will be the only publicly listed pure play parking owner of scale. Since we took ownership of the assets, we have been working to reposition the portfolio to establish an institutional platform focused on driving shareholder value through our unique approach to active asset management. We have already started on this growth journey as we have negotiated new lease structures, implemented an active asset management strategy with our proprietary technology and refocused on capturing demand from multiple sources at each asset. We are making progress and still have what we believe is a lot of embedded value creation opportunities.

00;04;00;09 - 00;04;24;23

Manuel Chavez

Lastly, I’ll reiterate the investment highlights. Parking is a compelling asset class. We have a best-in-class platform. The portfolio has attractive in-place revenue with potential upside and we are uniquely positioned to consolidate a fragmented market. And as a final reminder, please vote and please vote yes.

Certain of these risks are identified and discussed in the section of the Joint Proxy Statement/Prospectus titled “Risk Factors.” These risk factors will be important to consider in determining future results and should be reviewed in their entirety. These

Readers should carefully review the statements set forth in the reports, which FWAC and MIC have filed or will file from time to time with the SEC.

In addition to factors previously disclosed in FWAC’s and MIC’s reports filed with the SEC, including FWAC’s and MIC’s most recent reports on Form 8-K and all attachments thereto, which are available, free of charge, at the SEC’s website at www.sec.gov, and those identified elsewhere in this document, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: risks and uncertainties related to the inability of the parties to successfully or timely consummate the proposed transactions, including the risk that any required regulatory approvals or securityholder approvals of FWAC or MIC are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed transactions are not obtained, failure to realize the anticipated benefits of the proposed transactions, risks related to MIC’s ability to execute on its business strategy, attain its investment strategy or increase the value of its portfolio, act on its pipeline of acquisitions, attract and retain users, develop new offerings, enhance existing offerings, compete effectively, and manage growth and costs, the duration and global impact of COVID-19, the possibility that FWAC or MIC may be adversely affected by other economic, business and/or competitive factors, the number of redemption requests made by FWAC’s public shareholders, the ability of MIC and FWAC to leverage Fifth Wall’s affiliates and other commercial relationships to grow MIC’s customer base (which is not the subject of any legally binding obligation on the part of Fifth Wall or any of its partners or representatives), the ability of each of MIC and FWAC to leverage its relationship with any other company investor (including investors in the PIPE transaction) to grow MIC’s customer base, the ability of the combined company to meet the NYSE’s or NYSE American’s listing standards (or the standards of any other securities exchange on which securities of combined company are listed) following the proposed transactions, the risk that the announcement and consummation of the transaction disrupts MIC’s current plans and operations, costs related to the transaction, changes in applicable laws or regulations, the outcome of any legal proceedings that may be instituted against MIC, FWAC, or any of their respective directors or officers, following the announcement of the transaction, the ability of FWAC or combined company to issue equity or equity-linked securities in connection with the proposed transactions or in the future, the failure to realize anticipated pro forma results and underlying assumptions, including with respect to estimated shareholder redemptions and purchase price and other adjustments; and those factors discussed in documents of MIC and FWAC filed, or to be filed, with the SEC. Additional factors that could cause actual results to differ materially from those expressed or implied in forward-looking statements are also provided in the Joint Proxy Statement/Prospectus.

Any financial projections in this document are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond FWAC’s and MIC’s control. While all projections are necessarily speculative, FWAC and MIC believe that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection extends from the date of preparation. The assumptions and estimates underlying the projected results are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. The inclusion of projections in this document should not be regarded as an indication that FWAC and MIC, or their representatives, considered or consider the projections to be a reliable prediction of future events.

This document is not intended to be all-inclusive or to contain all the information that a person may desire in considering an investment in FWAC or MIC and is not intended to form the basis of an investment decision in FWAC or MIC. All subsequent written and oral forward-looking statements concerning FWAC and MIC, the proposed transactions, or other matters, and attributable to FWAC and MIC or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above.
