Airspan Networks, a Leading 5G Technology Company to Go Public through Merger with
New Beginnings Acquisition Corp. (NYSE American: NBA)

BOCA RATON, FL – Monday, March 8, 2021 – Airspan Networks Inc. (Airspan), which provides groundbreaking, disruptive software and hardware for 5G network solutions, has entered into a definitive business combination agreement with and into New Beginnings Acquisition Corp. (NBA) (NYSE American: NBA), a special purpose acquisition company (SPAC). The combination is expected to have an enterprise value of nearly $822 million. Upon closing of the business combination, expected in the third quarter of 2021, NBA will be renamed “Airspan Networks Holdings Inc.,” a publicly listed company, which is expected to be listed on the NYSE American with the ticker symbol “MIMO.”

We believe the wireless industry is poised for rapid deployment of 5G technology. The recent success of the U.S. government’s $80 billion+ C-band spectrum auction demonstrates significant levels of investment from operators and new market entrants.

We believe Airspan’s sophisticated network equipment infrastructure allows maximum efficiency of wireless spectrum, which is an increasingly expensive and scarce resource. Network operators are also accelerating adoption of virtualization and densification, changing their reliance on proprietary hardware to a focus on software and cloud architecture. These trends are expected to provide Airspan with an opportunity to take market share from the legacy network providers and enter new high growth market segments such as Private 5G and Fixed Wireless Access, which are addressable markets in the new telecom paradigm.

“These seismic 5G industry trends play right into Airspan’s strengths,” said Eric Stonestrom, President and CEO of Airspan. “This transaction is expected to help fund our growth plans and accelerate our vision of providing our customers with leading edge 5G networks. We are at the precipice of a significant capital-intensive upgrade as 5G deployments drive the future growth of existing mobile carriers, new market entrants, and private and enterprise buildouts that we believe will transform numerous industries.”

With more than 1,000 customers in over 100 countries worldwide, we believe Airspan is at the forefront of breakthrough 5G RAN and Fixed Wireless Access solutions, with increasing convergence between fixed broadband and mobile use cases and operators. We believe Airspan is uniquely positioned in the expanded addressable market of communications equipment for operators providing high speed wireless connectivity that will dominate the TMT landscape in the decade to come.

Airspan Technology “Key Enabler” of 5G

“Dense, software-centric 5G network builds are crucial for telcos today. Airspan’s technology is a key enabler in this space, which is why SoftBank has invested in Airspan over multiple rounds,” said Michel Combes, President SoftBank Group International.

“We are delighted to partner with Airspan, a first mover in this exciting and rapidly expanding new 5G market,” said Michael Liebowitz, CEO and Director of New Beginnings Acquisition Corp. “As 5G networks are rolled out, Airspan is leading the way with its breakthrough Open RAN technology with significant potential for growth serving incumbent and emerging carriers, and also addressing new “private 5G” segments including in building 5G, Distributed Antenna System (DAS) building replacements, connected and autonomous vehicles (CAVs), automated port operations, air-to-ground in-flight connectivity, Smart Industry 4.0 factories and optimized Smart Grid driven utilities. This transaction will bring the vision of Eric and the Airspan team to fruition.”

Transaction Overview

New Beginnings Acquisition Corp., which currently holds approximately $116 million in trust, will combine with Airspan at an estimated pro forma enterprise value of nearly $822 million. Assuming no redemptions by NBA’s existing public stockholders, Airspan’s existing stockholders will hold approximately 75% of the fully diluted shares of common stock in the combined company, Airspan Networks Holdings Inc., immediately following the closing of the business combination.

The combined company expects to receive approximately $166 million in net proceeds, assuming no redemptions by NBA’s existing public stockholders, including proceeds from a $75 million PIPE transaction. Cash proceeds are expected to be used to accelerate Airspan’s 5G revenue growth, to expand its product portfolio, and for working capital to fund increasing demand.

The transaction has been unanimously approved by the board of directors of both NBA and Airspan, and is subject to the satisfaction of customary closing conditions, including the approval of both parties’ stockholders, expiration of Hart-Scott-Rodino waiting periods and the effectiveness of NBA’s registration statement with the Securities and Exchange Commission (SEC). The transaction is expected to close in the third quarter of 2021.

Non - GAAP Financial Measures This Presentation includes certain financial measures not presented in accordance with generally accepted accounting principl es (“GAAP”) including, but not limited to, EBITDA and certain ratios and other metrics derived therefrom. These non - GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding an d assessing the Company’s financial results. Therefore, these measures should not be considered in isolation or as an alterna tiv e to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be awa re that the Company’s presentation of these measures may not be comparable to similarly - titled measures used by other companies. The Company believes these non - GAAP measures of financial results provide useful information to management and investors regardi ng certain financial and business trends relating to the Company’s financial condition and results of operations. The Company believes that the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating ongoin g operating results and trends in and in comparing the Company’s financial measures with other similar companies, many of whi ch present similar non - GAAP financial measures to investors. These non - GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non - GAAP financial measures. Please refer to any footnotes where presented in this Presentation, as well as to the table on the f ina l page, for a reconciliation of these measures to what the Company believes are the most directly comparable measure evaluate d i n accordance with GAAP. This Presentation also includes certain projections of non - GAAP financial measures. Due to the high variability and difficulty i n making accurate forecasts and projections of some of the information excluded from these projected measures, together with som e of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be r equ ired to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no dis clo sure of estimated comparable GAAP measures is included and no reconciliation of the forward - looking non - GAAP financial measures is in cluded. Certain monetary amounts, percentages and other figures included in this Presentation have been subject to rounding adjustmen ts. Certain other amounts that appear in this Presentation may not sum due to rounding. Use of Projections This Presentation contains financial forecasts with respect to the Company’s projected financial results, including Revenue, Gro ss Profit, Net Income and EBITDA, for the Company’s fiscal years 2020 through 2023. The Company’s independent auditors have n ot audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Pre sen tation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the pur pose of this Presentation. These projections constitute forward - looking information, are for illustrative purposes only and should not b e relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective fin anc ial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risk s a nd uncertainties that could cause actual results to differ materially from those contained in the prospective financial infor mat ion. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company o r t hat actual results will not differ materially from those presented in the prospective financial information. Inclusion of the pr ospective financial information in this Presentation should not be regarded as a representation by any person that the results containe d i n the prospective financial information will be achieved. Industry and Market Data In this Presentation, New Beginnings and the Company rely on and refer to certain information and statistics obtained from th ird - party sources which they believe to be reliable.

Exhibit 99.3

EMAIL SUBJECT: Airspan is Going Public!

Dear Airspan Team,

Great news! We are excited to announce we plan to go public and list our stock on the NYSE American stock exchange. This milestone will be accomplished through a merger with and into an already publicly traded special purpose acquisition company (SPAC), New Beginnings Acquisition Corp. (“NBA”) (NYSE American: NBA). You can read the news release we just distributed externally here: www.airspan.com/news/.

We will continue to operate under the Airspan name and there will be no substantive changes to our team or how we do business. Airspan will become a public company when the deal is complete, expected to trade on the NYSE American stock exchange under the new ticker symbol “MIMO”. The boards of directors of both Airspan and NBA have unanimously approved the proposed transaction, which is expected to be completed in the third quarter of 2021.

We Operate at Scale: 1,000+ Customers in More than 100 Countries

There is still work to be done to close this transaction. But once the merger is approved, it will deliver significant financial resources to accelerate our strategic growth plans, and substantially enhance our balance sheet.

Strict Guidelines around Publicity

As we enter this new chapter, there are some rules we need to follow. The US Securities and Exchange Commission (SEC) has strict guidelines around publicity. To avoid delays or any other repercussions the SEC might impose if we do not adhere to these rules, we must avoid speaking publicly about this process and our business metrics and financials. Airspan employees are limited to providing data that is only publicly released by Airspan. Accordingly, I ask that you please refrain from making any statements about our company or this event publicly.

Inquiries from the Media

With this in mind, this is a good time to remind you that only our Communications team should interact with journalists, bloggers and industry analysts. If you are contacted by the media, please immediately refer her/him to Howie Waterman, hwaterman@airspan.com, 917-359-5505, and Paul Wakefield, pwakefield@airspan.com, 011 44 7774 622615.

If someone asks you about the process of going public or company fundamentals, the best response is to simply say, “We’re really proud and excited. Due to federal regulations, I can’t speak to that, but I would be happy to connect you with the appropriate team members.” Understanding that communications are highly regulated through this process, please know we will continue to share updates with you as we have more to report.

In addition, until the disclosure documents relating to the transaction are filed with the SEC, you should not transact in NBA stock.

It is an exciting time for all of us at Airspan and I want to take this moment to thank everyone for your continued hard work, dedication, partnership and support toward helping us achieve our company vision and business objectives. We look forward to working with you in this next phase of our business evolution, as we continue to deliver our superior connectivity solutions to fuel the global 5G network transformation.

We will host a joint investor conference call with NBA to discuss the proposed transaction this morning at 8 AM EST. To access the conference call, please visit https://www.nbaspac.com, or call 1-844-512-2921 (toll/international 1-412-317-6671) and enter passcode 1143845.

Cautionary Statement Regarding Forward-Looking Statements

This communication contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements about future financial and operating results, our plans, objectives, expectations and intentions with respect to future operations, products and services; and other statements identified by words such as “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimated,” “believe,” “intend,” “plan,” “projection,” “outlook” or words of similar meaning. These forward-looking statements include, but are not limited to, statements regarding Airspan’s industry and market sizes, future opportunities for NBA, Airspan and the combined company, NBA’s and Airspan’s estimated future results and the Proposed Transaction, including the implied enterprise value, the expected transaction and ownership structure and the likelihood and ability of the parties to successfully consummate the Proposed Transaction. Such forward-looking statements are based upon the current beliefs and expectations of our management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are difficult to predict and generally beyond our control. Actual results and the timing of events may differ materially from the results anticipated in these forward-looking statements.

In addition to factors previously disclosed in NBA’s reports filed with the SEC and those identified elsewhere in this communication, the following factors, among others, could cause actual results and the timing of events to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (i) the risk that the Proposed Transaction may not be completed in a timely manner or at all, which may adversely affect the price of NBA’s securities; (ii) the risk that the transaction may not be completed by NBA’s Business Combination deadline and the potential failure to obtain an extension of the Business Combination deadline if sought by NBA; (iii) the failure to satisfy the conditions to the consummation of the Proposed Transaction, including the adoption of the business combination agreement by the stockholders of NBA and Airspan, the satisfaction of the minimum trust account amount following redemptions by NBA’s public stockholders and the receipt of certain governmental and regulatory approvals; (iv) the lack of a third party valuation in determining whether or not to pursue the Proposed Transaction; (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the business combination agreement; (vi) the impact of COVID-19 on Airspan’s business and/or the ability of the parties to complete the Proposed Transaction; (vii) the effect of the announcement or pendency of the transaction on Airspan’s business relationships, performance and business generally; (viii) risks that the Proposed Transaction disrupts current plans and operations of Airspan; (ix) the outcome of any legal proceedings that may be instituted against Airspan or NBA related to the business combination agreement or the Proposed Transaction; (x) the ability to maintain the listing of NBA’s securities on the NYSE American; (xi) the price of NBA’s and the post-combination company’s securities may be volatile due to a variety of factors, including changes in the competitive and regulated industries in which Airspan operates, variations in performance across competitors, changes in laws and regulations affecting Airspan’s business and changes in the combined capital structure; (xii) the ability to implement business plans, forecasts, and other expectations after the completion of the Proposed Transaction, and identify and realize additional opportunities; (xiii) the risk of downturns and the possibility of rapid change in the highly competitive industry in which Airspan operates; (xiv) the risk that Airspan and its current and future collaborators are unable to successfully develop and commercialize Airspan’s products or services, or experience significant delays in doing so; (xv) the risk that the post-combination company may not achieve or sustain profitability; (xvi) the risk that the post-combination company will need to raise additional capital to execute its business plan, which may not be available on acceptable terms or at all; (xvii) the risk that the post-combination company experiences difficulties in managing its growth and expanding operations; (xviii) the risk that third-party suppliers and manufacturers are not able to fully and timely meet their obligations; (xix) the risk that the rollout and utilization of 5G technology will not provide the expected benefits; (xx) the risk that Airspan is unable to secure or protect its intellectual property; and (xxi) the risk that the post-combination company’s securities will not be approved for listing on the NYSE American or if approved, maintain the listing.

Actual results, performance or achievements may differ materially, and potentially adversely, from any projections and forward-looking statements and the assumptions on which those forward-looking statements are based. There can be no assurance that the data contained herein is reflective of future performance to any degree.
