#### To our shareholders,

#### Thank you.
This is my first annual letter, so I will take the liberty to discuss our operating philosophies and where we focus our energy here at BETA. We started BETA to create the future of aerospace and we are on a mission to do so. We have built an aerospace company capable of designing, certifying, manufacturing, operating, and supporting aircraft that reduce the cost, increases the reliability, and expands the reach of aviation. In the words of my friend and mentor Martine Rothblatt, we will "give humans access to the z-dimension of this world." That remains the mission.

It will take time and mental toughness. We are committed to the hard parts, the rewarding parts, and the disciplined work required to see it through. We are also committed to delivering for those of you who have trusted us with your investment and believed in us.

As an aviator, engineer, test pilot, and fabricator, I have a simple view of this business: aerospace rewards discipline and eliminates everything else. There is no room for off-point designs, unnecessary complexity, or engineering that only works in ideal conditions. Aircraft have to work in weather, under load, with normal wear, and in the hands of discerning customers, maintainers, regulators, and operators who depend on them every day.

That is the standard we are building toward.

BETA's competitive advantage is not one feature, one aircraft, or one program. It is the system we have built: simple, certifiable aircraft; vertically integrated enabling technologies (such as bare metal flight controllers, simple motors, robust batteries, and charging infrastructure); manufacturing capability; real-world operating experience; and a culture that puts every dollar and every engineering hour toward the highest-value work because we are focused on the outcome, the mission.

We are fortunate to be at this point in time. We have a nearly unconstrained market opportunity with the confluence of the right technologies at our disposal, a regulatory environment that is ready to embrace technological advancements, and a market that is asking for a better way to move goods and people. The regulatory barrier to entry has always been high in aerospace, which has precluded small advancements over the last 50 years, but this massive asset of unconsumed technology is offering a huge advancement.

The regulatory environment is beginning to support the safe introduction of Advanced Air Mobility. And the foundational technologies we rely on, semiconductors, batteries, controls, software, and manufacturing systems, continue to improve. Aerospace has historically had high barriers to entry, which limited the pace of change. Today, those barriers are still real, but the available technology and its benefits, when engineered in correctly, are greater.

We have done more than others in this space with less capital and fewer people because we have been deliberate about what we build, what we avoid, and in what order we take on risk. We have stayed focused on simple and effective designs, pragmatic sequencing, and disciplined execution. That is what I believe is required to employ today's technology and advance our mission.

First, prove we can certify the core technology. Then certify an electric airplane. Then bring the certified eVTOL to market. Then use the same materials data, validated models, quality systems, and engineering processes to move into larger and more capable aircraft. Each step builds capability, credibility, operating data, customer confidence, and manufacturing muscle for the next one.

------

#### **TABLE OF CONTENTS**
In 2025, that approach continued to prove itself.

We advanced certification work, earned propulsion contracts, flew production-intent aircraft, expanded our charging network, grew our aircraft and component backlog, deepened partnerships with GE, Embraer, GD, and others, continued to put miles on aircraft in real environments and added amazing talent to our team. We also laid more of the manufacturing foundation required for the next phase of the company. We were fortunate to do this with new leadership in the FAA that created an organization and safe path for Advanced Air Mobility entry into service.

Advanced Air Mobility will not be won by the company with the best animation or the loudest marketing. It will be won by the company that can certify, build, deliver, support, and improve aircraft safely and economically over a long period of time.

Simplicity is central to that advantage.

Our aircraft are designed around operational robustness: limited moving parts; no liquid cooling; no gearboxes; no thrust vectoring; and no variable-pitch propellers where they are not needed. That simplicity reduces cost, improves reliability, supports manufacturability, and matters enormously in the field. Many of us at BETA are commercial pilots, maintainers, builders, and aircraft owners. We love what we do, and we love to fly.

Reliable, simple aircraft endure. More importantly, they fly every day.

Operational robustness and simplicity matter in commercial passenger operations. They matter in medical and cargo operations. And they matter in defense.

Defense has become one of the most important developing opportunities for BETA. The need is clear: reduce the logistics tail; reduce fuel dependency; improve operational flexibility; and field aircraft at a cost that allows them to be deployed in meaningful numbers. Rough fields, heat, dust, sand, weather, and austere maintenance environments do not favor unnecessary complexity. They favor aircraft that are simple, rugged, efficient, serviceable, and manufacturable. Our distributed propulsion architecture and systems approach are well suited to that need. Our hybrid VTOL aircraft flies faster than a helicopter, flies further than a helicopter and carries a real payload while offering the operational flexibility of vertical takeoff and landing from ships, islands and unimproved bases… without a pilot.

Defense also relies on production at scale. BETA aircraft have been designed with rate manufacturing in mind, and we have invested in the facilities, tooling, and processes to support that ambition. The people here at BETA are proud to support our military service members with simple, robust technology and manufacturing capabilities designed to produce aircraft at rates not seen since WWII.

Our partnerships are also strengthening. The work with GE has moved quickly because both teams are focused on engineering, building, testing, and learning. We have passed the first major milestones in the GE-BETA turbogenerator program, and the work has created a broader opportunity for BETA's technology and engineering capability. In Brazil, Embraer flying on BETA propulsion is a source of real pride for our team. Their success is our success, and every flight demonstrates the value of the propulsion technology and the trust we are earning as an aerospace supplier to a great company.

We also continue to build the infrastructure around the aircraft. Our charging network is not separate from the aircraft. It is part of the system. Aircraft, chargers, training, service, software, operations, and manufacturing all have to work together as this technology moves from promise to daily use. We think about BETA as an integrated aerospace company, not simply an aircraft developer.

Our capital allocation follows the same logic.

We have been careful with capital because the work ahead is hard and the opportunity is long-term. We have invested in engineering, certification, flight test, manufacturing, charging infrastructure, and the people who make those capabilities real. In all cases, we have tried to avoid spending that creates the appearance of progress without durable value. We have made mistakes, and we have tested systems that did not pass. That is part of serious innovation and engineering. The important question is whether those dollars bought learning, reduced risk, and improved the product. Our balance sheet gives us room to execute, but our standard remains unchanged: each dollar should advance certification, customer value, operational readiness, manufacturability, and ultimately long-term owner value.

------

The team is the reason any of this works.

When you walk through the doorway into BETA, you can feel it: the work ethic; the ingenuity; the passion for aviation; and the willingness to solve hard problems without drama. A quote in the stairway of our R&D center reads, *"No problem can withstand the assault of sustained thinking"* – Voltaire.

Some problems have proven harder than I expected. One is translating rules originally written around turbine engines now being applied to electric motors. Correlations that are clear to me looking through the lens of physics are not clear to the legal teams interpreting the newly minted rules. One thing is certain to me; we are leading this work, we sometimes have to help clear the path for the industry.

Another challenge has been integrating experienced people from a wide range of successful aerospace companies into one common BETA standard. There are many good drawing standards, software tools, and processes in aerospace. The hard work is choosing ours, aligning the team around them, and applying them consistently.

Since becoming a public company, we have seen a larger and higher-quality talent pipeline, and we are continuing to grow at the right pace. In aerospace, culture shows up directly in the machine. It shows up in design reviews, in the shop, on the flight line, in test discipline, and in the way problems get solved before they become crises.

Looking ahead, our priorities are clear.

We will continue to advance certification, deliver aircraft and support eIPP operations, expand the charging network, scale manufacturing, deepen our defense and commercial partnerships, and maintain capital discipline. The FAA has set a high safety bar. That is exactly as it should be. Few companies can meet it. We believe BETA can.

I am confident in our strategy: simple systems, rigorous engineering, real-world operations, capital discipline, and promises kept.

We do not control the daily movement of our share price. We do control the quality of our engineering, the discipline of our capital allocation, the pace of our certification work, the strength of our customer relationships, and the durability of the company we are building. By those measures, I believe BETA is stronger and fundamentally more valuable today than the day we became public. I am more convinced than ever that we made the right technical and market-entry strategy decisions, and that this team will continue to focus and deliver.

To our employees, customers, partners, and shareholders: thank you. You have backed a team taking on one of the hardest and most important engineering challenges in aviation. This is still day-1 for electric aviation and advanced air mobility. We believe BETA will change the way people fly, safely and efficiently.

We understand the responsibility that comes with your trust.

We intend to continue to earn it.

Regards,

Kyle Clark

&nbsp;&nbsp;&nbsp;&nbsp;(1) Francesco Capretti transitioned off our Board in 2025 in connection with our initial public offering ("IPO").

&nbsp;&nbsp;&nbsp;&nbsp;(2) Dean Kamen resigned from our Board, effective February 18, 2026.

We believe that in order for our Board to effectively guide us to long-term sustainable and dependable performance, it should be composed of individuals with sophistication and experience in the many disciplines that impact our business. In order to best serve our stockholders, we seek to have a Board, as a whole, that is competent in key corporate disciplines, including accounting and financial acumen, business judgment, crisis management, governance, leadership, people management, risk management, social responsibility and reputational issues, and strategic planning. The Nominating & Corporate Governance Committee believes that all directors must, at a minimum, meet the criteria set forth in the Board's Code of Ethics and the Corporate Governance Guidelines, which specify, among other things, that the Nominating & Corporate Governance Committee will consider criteria such as independence, skills, and experience in the context of the needs of the Board. When considering the selection of director nominees, the Nominating & Corporate Governance Committee considers individuals with varied backgrounds, viewpoints, accomplishments, and professional expertise, among other factors. The Nominating & Corporate Governance Committee also will consider a combination of factors for each director, including: (a) the nominee's ability to work in and promote a productive environment; (b) whether the nominee has sufficient time and willingness to fulfill the substantial duties and responsibilities of a director; (c) whether the nominee has demonstrated the high level of character, ethics, and integrity expected by the Company; (d) whether the nominee possesses the broad professional and leadership experience and skills necessary to effectively respond to the complex issues encountered by a publicly-traded company; and (e) the nominee's ability to apply sound and independent business judgment.

The Nominating & Corporate Governance Committee has determined that all of our directors meet the criteria and qualifications set forth in our Code of Ethics, our Corporate Governance Guidelines, and the criteria set forth above for director nominees. Moreover, each director possesses the following critical personal qualities and attributes that we believe are essential for the proper functioning of the Board to allow it to fulfill its duties for our stockholders: accountability, ethical leadership, governance, integrity, risk management, and sound business judgment. In addition, our directors have the confidence to assess and challenge the way things are done and

------

#### **TABLE OF CONTENTS**
recommend alternative solutions; a keen awareness of our business and social realities of the environment in which we operate; the independence and high performance standards necessary to fulfill the Board's oversight function; and the humility, professional maturity, and style to interface openly and constructively with other directors.

Subject to any earlier resignation or removal in accordance with the terms of our Certificate, our Class I directors will serve until this annual meeting of stockholders. Our Class II directors will serve until our 2027 annual meeting of stockholders, and our Class III directors will serve until our 2028 annual meeting of stockholders. In addition, our Certificate provides that our directors may be removed with or without cause by the affirmative vote of at least a majority of the voting power of our outstanding shares of stock entitled to vote thereon, voting together as a single class for so long as the outstanding Class B common stock represents 35% or more of the voting power of the then outstanding shares of our capital stock entitled to vote generally in the election of directors ("Voting Stock"). If the outstanding Class B common stock no longer represents 35% or more of our Voting Stock, then our directors may be removed only for cause upon the affirmative vote of at least 66 2∕3% of the voting power of our outstanding shares of stock entitled to vote thereon.

#### GE Aerospace Nomination Rights
Our Certificate provides General Electric Company, operating as GE Aerospace ("GE Aerospace"), with the right to designate one individual for election to our Board (the "Director Designation Right") for so long as either (i) GE Aerospace beneficially owns at least 6,217,138 shares of Class A common stock or (ii) there is a Commercial Relationship (as defined in our letter agreement with GE Aerospace). At any time when GE Aerospace has neither the minimum ownership threshold nor the Commercial Relationship requirement, the Director Designation Right will terminate. See "Certain Relationships and Related Party Transactions—Letter Agreement with GE Aerospace."

In addition, pursuant to the voting rights letter agreement, dated September 26, 2025, between Mr. Clark and the Company, Mr. Clark has agreed to vote all of the shares of the Company's capital stock entitled to vote and held by him in favor of the director designated pursuant to GE Aerospace's Director Designation Right at any meeting of the stockholders of the Company and in any written consent of stockholders and in favor of not removing such director without GE Aerospace's affirmative consent. See "Certain Relationships and Related Party Transactions—Voting Rights Letter Agreement" for additional information related to such agreement.

#### Stockholder Recommendations for Director Nominees
The Nominating & Corporate Governance Committee will consider stockholder nominations for membership on the Board. For the 2027 Annual Meeting, nominations may be submitted to BETA Technologies, Inc., 1150 Airport Drive, South Burlington, VT 05403, Attn: Chief Legal Officer and Secretary, and such nominations will then be forwarded to the Chair of the Nominating & Corporate Governance Committee. Recommendations must be in writing and we must receive the recommendation no later than the close of business on March 13, 2027 and not earlier than the close of business on February 11, 2027. Recommendations must also include certain other procedural requirements as specified in our Bylaws.

When filling a vacancy on the Board, the Nominating & Corporate Governance Committee identifies the desired skills and experience of a new director and nominates individuals who it believes can strengthen the Board's capabilities and further diversify the collective experience represented by the then-current directors. The Nominating & Corporate Governance Committee may engage third parties to assist in the search and provide recommendations. Also, directors are generally asked to recommend candidates for the position. The candidates are then evaluated based on the process outlined in our Corporate Governance Guidelines and the Nominating & Corporate Governance Committee charter, and the same process is used for all candidates, including candidates recommended by stockholders.

Each nominee was recommended for re-election by the Nominating & Corporate Governance Committee for consideration by the Board and our stockholders. If, before the Annual Meeting, any nominee becomes unable to serve, or chooses not to serve, the Board may nominate a substitute. If that happens, the persons named as proxies on the proxy card will vote for the substitute. Alternatively, the Board may either let the vacancy stay unfilled until an appropriate candidate is identified or reduce the size of the Board to eliminate the unfilled seat. As of the mailing of these proxy materials, the Board has no reason to believe any director nominee would not be available to serve.

#### Vote Required and Board Voting Recommendation
Directors will be elected at the Annual Meeting by a plurality of the votes cast in respect of the shares present in person or represented by proxy and entitled to vote on the election of directors. Abstentions and broker non-votes will have no effect on the voting results for the election of directors.

#### CORPORATE GOVERNANCE

#### General
Our Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics, and charters for our Audit Committee, Compensation Committee, and Nominating & Corporate Governance Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines, and our Code of Ethics in the "Governance Documents" section of investors.beta.team.

#### Independence Status
The listing standards of the NYSE require that, subject to specified exceptions, such as those described below under the subsection entitled, "Controlled Company Status", each member of a listed company's Audit Committee, Compensation Committee, and Nominating Committee be independent and that Audit Committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act.

Our Board has determined that John Abele, Chuck Davis, Michael Stone and James McConville meet the requirements to be an independent director. In making this determination, our Board considered the relationships that each non-employee director has with the Company and all other facts and circumstances that our Board deemed relevant in determining their independence, including beneficial ownership of our Common Stock.

#### Controlled Company Status
Kyle Clark, our founder and Chief Executive Officer, controls a majority of our Voting Stock. As a result, we will remain a "controlled company." Under New York Stock Exchange ("NYSE") rules, a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company is a "controlled company" and may elect not to comply with certain NYSE corporate governance requirements. Therefore, we are permitted to, and have elected not to comply with certain corporate governance requirements of the NYSE, including that: (1) a majority of our Board consist of independent directors, (2) our Board have a compensation committee that is comprised entirely of independent directors, (3) our Board have a nominating and corporate governance committee that is comprised entirely of independent directors and (4) our Board conduct an annual performance evaluation of the compensation committee and nominating and corporate governance committee. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the NYSE corporate governance requirements.

#### Board Meetings and Committees
We completed our IPO in November 2025. For the year ended December 31, 2025, our Board held four meetings. Our Audit Committee held one meeting during 2025 and our Compensation Committee held one meeting during 2025. Directors are expected to attend all or substantially all of the Board meetings and meetings of committees on which they serve. In 2025, each director attended at least 75% of an aggregate of the meetings of the Board during such director's tenure and the total number of meetings held by any of the committees of the Board on which the director served.

Our Board has a standing Audit Committee, a standing Compensation Committee, and a standing Nominating & Corporate Governance Committee. The composition, duties, and responsibilities of these committees are as set forth below. In the future, our Board may establish other committees, as it deems appropriate, to assist it with its responsibilities.

In addition, our Board has determined that each of Messrs. Davis and Stone qualifies as an "audit committee financial expert," as such term is defined in Item 407(d)(5) of Regulation S-K.

The Board has adopted a written charter for the Audit Committee, which is available on the investor relations section of our website at investors.beta.team/governance/governance-documents. Our website is not part of this Proxy Statement.

&nbsp;&nbsp;&nbsp;&nbsp;1. developing and recommending to our Board criteria for board and committee membership;

&nbsp;&nbsp;&nbsp;&nbsp;2. subject to the rights of GE Aerospace under our Charter, identifying and recommending to our Board the persons to be nominated for election as directors and to each of our Board's committees;

&nbsp;&nbsp;&nbsp;&nbsp;4. developing and recommending to our Board a set of corporate governance guidelines; and

The Board has adopted a written charter for the Nominating & Corporate Governance Committee, which is available on the investor relations section of our website at investors.beta.team/governance/governance-documents. Our website is not part of this Proxy Statement.

#### Board Leadership Structure
The following section describes our Board leadership structure, the reasons why the structure is in place at this time, the roles of various positions, and related key governance practices. Our Board believes the mix of experienced independent and non-independent directors, as well as management directors that make up our Board, along with the role of our Chair and our Board committee composition, benefits BETA and its stockholders.

#### Independence; Board Mix
Our Board has an effective mix of independent, non-independent, and management directors. Our Board includes four independent directors, including our current Chair Chuck Davis, five non-independent directors, including the GE representative, Amy Gowder, our Chief Executive Officer, Kyle Clark, and our Chief Technology Officer, Dr. David Churchill.

#### Chair
Chuck Davis has been our Chair since April 2021. Mr. Davis has extensive knowledge and experience in a variety of relevant areas acquired through his professional and other experiences, including his distinguished career

------

#### **TABLE OF CONTENTS**
advising companies and his extensive knowledge of corporate finance. This knowledge and experience give Mr. Davis the insight necessary to navigate the responsibilities of strategic development and execution and provide overall guidance to our Chief Executive Officer as to the Board's views and perspectives.

With respect to the roles of Chair of the Board and Chief Executive Officer, our Corporate Governance Guidelines provide that the roles may be separated or combined, and the Board will exercise its discretion in combining or separating these positions as it deems appropriate in light of prevailing circumstances. The roles of Chair of the Board and Chief Executive Officer are currently separated. The Board believes that this structure clarifies the individual roles and responsibilities of Chief Executive Officer and Chair of the Board, streamlines decision-making and enhances accountability. The Board believes that, at this time, separating the roles of Chair and Chief Executive Officer is the most effective leadership structure because it allows Mr. Clark to focus on the management of the Company, day-to-day operations and engaging with external stakeholders, while Mr. Davis focuses his attention on the broad strategic issues considered by the Board, leveraging his strong public company background to provide strategic guidance and effective oversight of management, engaging with the Chief Executive Officer between Board meetings and providing guidance to Mr. Clark.

#### Insider Trading Policy; Hedging Transactions
We have adopted an Insider Trading Policy that is designed to promote compliance with insider trading laws, rules, and regulations, as well as NYSE listing standards. Our Insider Trading Policy prohibits the trading of our securities on the basis of material, non-public information, establishes regular quarterly blackout periods, specifies procedures for seeking clearance to trade by certain designated employees, requires that all insider Rule 10b5-1 trading plans comply with applicable law, including with respect to cooling off periods, and provides for consequences of violating the Insider Trading Policy or the federal securities laws. Pursuant to our Insider Trading Policy, we prohibit our employees, directors, and officers from engaging in hedging or monetization transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds, without specific approval from the Legal Department. Additionally, directors, officers, and other employees are prohibited from holding our securities in a margin account or otherwise pledging our securities as collateral for a loan, subject to specific written approval from the Legal Department. A copy of our Insider Trading Policy was filed as an exhibit to the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

#### Clawback Policy
In connection with our IPO, our Board adopted a Clawback Policy (the "Clawback Policy") that complies with the NYSE's clawback rules promulgated under Section 10D of the Exchange Act and the rules promulgated thereunder. In the event the Company is required to prepare an accounting restatement of its financial statements due to the Company's material noncompliance with any such financial reporting requirement, the Clawback Policy requires that covered executives must reimburse the Company or forfeit any excess incentive-based compensation "received" (as defined under the clawback rules) by such covered executive during the three completed fiscal years immediately preceding the date on which the Company is required to prepare the restatement. Executives covered by the Clawback Policy are current and former executive officers, as determined by the Compensation Committee in accordance with Section 10D of the Exchange Act and the NYSE listing standards. Incentive-based compensation subject to the Clawback Policy includes any cash or equity compensation that is granted, earned, or vested based wholly or in part on the attainment of a financial reporting measure. The amount subject to recovery is the excess of the incentive-based compensation received based on the erroneous data over the incentive-based compensation that would have been received had it been based on the restated results.

#### Executive Sessions of Our Board of Directors
Our independent directors are provided the opportunity to meet in executive sessions at each regularly scheduled meeting of our Board.

#### Risk Oversight
Our management team is responsible for the day-to-day management of risks we face, while our Board, assisted by its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board has the responsibility to ensure that the risk management processes our management team has designed and implemented are appropriate and functioning adequately. To that end, our Board believes that open communication between our

------

#### **TABLE OF CONTENTS**
management team and the Board is essential for effective risk management and oversight. Our Chief Executive Officer and other members of the senior management team attend the meetings of our Board and its committees, as well as such other meetings as the Board or its committees deem appropriate, where, among other topics, they discuss strategy and key risks facing the Company. In this respect, our full Board reviews strategic and operational risk in the context of reports from our management team, and evaluates the risks inherent in significant transactions and events.

Our Board oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, improve long-term organizational performance, and enhance stockholder value. A fundamental part of risk management is not only understanding the most significant risks a company faces and what steps management is taking to manage those risks but also understanding what level of risk is appropriate for a given company. The involvement of our full Board in reviewing our business is an integral aspect of its assessment of the Company's risk profile and also its determination of what constitutes an appropriate level of risk. In connection with its reviews of the operations of our business, our full Board addresses the primary risks associated with our business, such as strategic planning. Our Board appreciates the evolving nature of our business and industry and is actively involved with monitoring new threats and risks as they emerge.

#### Code of Ethics
We have adopted a code of ethics that applies to all of our employees, officers and directors, including those officers responsible for financial reporting. In April 2026, we amended our Code of Ethics to further align with applicable Federal Aviation Administration regulations and reinforce our commitment to safety as a core organizational value. Our Code of Ethics is available on our website at investors.beta.team/governance/governance-documents. We intend to disclose any amendments to the code, or any waivers of its requirements, on our website.

#### Compensation Committee Interlocks and Insider Participation
No interlocking relationships exist between the members of our Board and the board or compensation committee of any other company.

#### Communications by Stockholders and Other Interested Parties with the Board
Stockholders and other interested parties may contact an individual director, the Board as a group, or a specified Board committee or group, including the non-management or independent directors as a group, by sending regular mail to:

#### Emerging Growth Company Status
We are providing compensation information pursuant to the scaled disclosure rules applicable to "emerging growth companies" under the rules of the SEC. As an emerging growth company, we are exempt from certain requirements related to executive compensation, including the requirements to hold a nonbinding advisory vote on executive compensation and to provide information relating to the ratio of total compensation of our Chief Executive Officer to the median of the annual total compensation of all of our employees, each as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act.

------

#### **TABLE OF CONTENTS**
We will remain an emerging growth company until the earlier of: (a) the last day of the year following the fifth anniversary of the consummation of our IPO, (b) the last day of the year in which we have total annual gross revenue of at least $1.235 billion, (c) the last day of the year in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of the second quarter of such year, or (d) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

#### Narrative Disclosure to Summary Compensation Table
*Letter Agreements* 

In connection with our IPO, we entered into employment agreements with each of our NEOs. Each employment agreement provides for at-will employment and sets forth each NEO's annual base salary and opportunity to earn an annual cash incentive award, up to a maximum of 200% of the target bonus for each performance year. In addition, each of the employment agreements provides that, upon termination of the NEO's employment by the Company for any reason other than for "cause," or by the NEO for "good reason," each as defined therein, subject to the NEO's execution, delivery, and non-revocation of a general release of all claims in favor of the Company, the NEO will be entitled to severance consisting of (in addition to accrued benefits): (i) six months of continued base salary payments and (ii) up to six months of continued Consolidated Omnibus Budget Reconciliation Act ("COBRA") premiums; provided that, if such termination occurs within the three months preceding or the 24 months following a "change in control" (as defined in the 2025 Plan), and if an NEO's employment is terminated involuntarily without "cause" within three months preceding or twenty-four months following the change in control, the NEO's severance entitlements shall consist of: (A) a lump sum cash payment equal to two times the sum of the respective NEO's base salary and target bonus for the year in which termination occurs, (B) a lump sum cash payment equal to the prorated target bonus for the year in which termination occurs, (C) a lump sum cash payment equal to 18 months of the NEO's monthly healthcare coverage premiums (or, if greater, the NEO's monthly COBRA premiums), and (D) full accelerated vesting of any then-outstanding equity awards (with performance-vesting awards to be deemed vested at target). Each employment agreement also provides that upon termination of an NEO's employment due to (x) death, all outstanding time-vesting equity awards will vest and (y) "disability" (as defined in the employment agreement), a prorated portion of outstanding time-vesting equity awards will vest, determined based on the number of calendar days from the applicable vesting commencement date through the termination date, plus an additional 365 days.

The employment agreements also contain non-competition and non-solicitation restrictions applicable during the term of employment and for six months thereafter, as well as assignment of inventions covenants, perpetual mutual non-disparagement and confidentiality provisions.

*Base Salary* 

Each of our NEOs receives a base salary. Base salary is a key, fixed element of each NEO's compensation and is intended to recognize the NEO's experience, skills, knowledge, and responsibilities. Each NEO's base salary for the fiscal year 2025 is set forth in the table below.

---

| | |
|:---|:---|
| **Named Executive Officer** | **Salary**  |
| Kyle Clark | $530000<sup>(1)</sup>  |
| Herman V. Cueto | $500000  |
| Brian Dunkiel | $412000 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Mr. Clark's base salary was increased to $815,000 in August 2025.

*2025 Cash Bonus* 

For fiscal year 2025, each of our NEOs was eligible to receive a discretionary cash bonus in such amount, if any, as determined in the sole discretion of (i) the Compensation Committee (with respect to any bonus paid to Mr. Clark) and (ii) Mr. Clark (with respect to any bonus paid to Mr. Cueto or Mr. Dunkiel) in respect of such NEO's performance. Messrs. Clark, Cueto, and Dunkiel received $2,132,000, $375,000, and $100,000, respectively, in connection with the fiscal year 2025 discretionary performance bonuses.

------

#### **TABLE OF CONTENTS**
*IPO Cash Bonus* 

In November 2025, in connection with our IPO, our Board approved one-time discretionary cash bonus awards for our NEOs. These awards were intended to recognize the significant contributions of our executive team leading up to our IPO. Messrs. Clark, Cueto, and Dunkiel received $3,000,000, $500,000, and $250,000, respectively, in connection with the IPO bonuses.

*IPO Grants* 

In November 2025, in connection with our IPO, our Board approved RSU awards under our 2025 Omnibus Incentive Plan (the "2025 Plan") for our NEOs. The RSUs vest ratably over a four-year period, subject to continuous service. These awards were intended to recognize the significant contributions of our executive team leading up to our IPO and to provide long-term retention incentives following our transition to a public company.

*Post-IPO Long-Term Equity Incentive Program* 

Under our long-term equity incentive program, our NEOs receive a mix of RSUs and performance-based restricted stock units ("PSUs") as part of their total equity incentive compensation. The RSUs vest ratably over a four-year period, subject to continuous service. The PSUs will be eligible to be earned quarterly based on achievement of quarterly performance milestones established by the Company's Compensation Committee. To incentivize outperformance, the quarterly performance milestones will result in maximum available payout only if achieved in the initial quarter applicable, with available shares to be earned declining by 25% in each subsequent quarter, as illustrated in the table below.

We view the long-term equity incentive program as an essential component of our executive compensation framework and it reflects the Compensation Committee's commitment to reward timely execution, operational discipline, long-term shareholder value creation, and improved retention.

In January 2026, each of our NEOs received RSU and PSU awards under our long-term equity incentive program. In April 2026, the Company's Compensation Committee certified achievement against the quarterly PSU performance objective for the three months ended March 31, 2026, resulting in payout at 100% for this quarterly milestone.

*Option Awards* 

In response to Item 402(x)(1) of Regulation S-K, the Company has not granted any new awards of stock options, stock appreciation rights, or similar option-like instruments since its IPO. Accordingly, the Company has no specific policy or practice on the timing of awards of such options in relation to the disclosure of material nonpublic information by the Company. In the event the Company determines to grant new awards of such options, the Board will evaluate the appropriate steps to take in relation to the foregoing.

*401(k) Plan* 

We maintain a retirement plan that is intended to be tax-qualified that provides all regular employees (including our Named Executive Officers) with an opportunity to save for retirement on a tax-advantaged basis. Under our 401(k) plan, participants may elect to defer a portion of their compensation on a pre-tax basis and have it contributed to the plan subject to applicable annual limits under the Code. Pre-tax contributions are allocated to each participant's individual account and are then invested in selected investment alternatives according to the participants' directions. Employee elective deferrals are 100% vested at all times.

#### Equity Incentives — 2018 Plan
The 2018 Plan was originally adopted by our Board and approved by our stockholders prior to our IPO. Under the 2018 Plan, we have reserved for issuance an aggregate of 25,084,129 shares of our Class A common stock. The

------

#### **TABLE OF CONTENTS**
number of shares of Class A common stock reserved for issuance is subject to automatic adjustment in the event of a stock split, stock dividend or other change in our capitalization.

The 2018 Plan permits the granting of (i) options to purchase common stock intended to qualify as incentive stock options under Section 422 of the U.S. Internal Revenue Code of 1986, as amended ("the Code"), and (ii) options that do not so qualify. The option exercise price of each option is determined by the administrator but may not be less than 100% of the fair market value of our Class A common stock on the date of grant. The term of each option will be fixed by the administrator and may not exceed 10 years from the date of grant.

Our Board is the administrator of the 2018 Plan. The administrator has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, and to determine the specific terms and conditions of each award. The administrator is authorized to exercise its discretion to reduce the exercise price of outstanding stock options or effect the repricing of such awards through cancellation and re-grants without stockholder approval. Persons eligible to participate in the plan are those officers, employees, directors, consultants and other advisors (including prospective employees, but conditioned upon their employment) of the Company and its subsidiaries as selected from time to time by the administrator in its discretion.

We do not expect to make any further awards under the 2018 Plan following the completion of our IPO.

#### Equity and Cash Incentives — 2025 Omnibus Incentive Plan
The 2025 Plan was adopted by our Board and approved by our stockholders in connection with our IPO. Under the 2025 Plan, employees, consultants, and directors of our Company and our affiliates performing services for us, including our executive officers, are eligible to receive awards. The 2025 Plan provides for the grant of options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, other stock-based awards, cash awards, and substitute awards intended to align the interests of service providers, including our NEOs, with those of our stockholders. We initially reserved 36,207,812 shares of our Class A common stock for issuance under the 2025 Plan. The number of shares of Class A common stock reserved for issuance is subject to automatic adjustment in the event of a stock split, stock dividend or other change in our capitalization. The total number of shares reserved for issuance under the 2025 Plan will be increased annually on January 1 of each calendar year, beginning in 2026 and ending and including January 1, 2035, by the lesser of (i) 5% of the aggregate number of shares of Class A common stock outstanding on December 31 of the immediately preceding calendar year and (ii) the number of shares of Class A common stock as is determined by our Board. Shares of Class A common stock subject to an award that expires or is canceled, forfeited, exchanged, settled in cash or otherwise terminated without delivery of shares and shares withheld to pay the exercise price of, or to satisfy the withholding obligations with respect to, an award will again be available for delivery pursuant to other awards under the 2025 Plan.

The 2025 Plan is administered by our Compensation Committee. The Compensation Committee has the authority to construe and interpret the 2025 Plan, grant awards and make all other determinations necessary or advisable for the administration of the plan. Awards under the 2025 Plan may be made subject to "performance conditions" and other terms.

#### Employee Stock Purchase Plan
The 2025 Employee Stock Purchase Plan (the "2025 ESPP") was adopted by our Board and approved by our stockholders in October 2025 in connection with our IPO. The 2025 ESPP is comprised of two distinct components in order to provide increased flexibility to grant rights to purchase shares under the ESPP that are intended to qualify for favorable U.S. federal tax treatment under Section 423 of the Code (the "Section 423 Component") and rights to purchase shares that are not intended to be tax-qualified under Section 423 of the Code.

Under the 2025 ESPP, participants will be offered the right to purchase shares of our Class A common stock at a discount during one or more offering periods, which may be successive or overlapping and will be selected by the plan administrator in its sole discretion with respect to which rights will be granted to participants. The plan administrator will designate the terms and conditions of each offering in writing, including the offering period, and may change the duration and timing of offering periods in its discretion. However, in no event may an offering period be longer than 27 months in length. The purchase price will be designated by the plan administrator, but, with respect to the 423 Component, will not be less than 85% of the fair market value of a share of our Class A common stock on the applicable enrollment date or the applicable exercise date, whichever is lower. We expect that all of our employees and employees of any designated subsidiary will be eligible to participate in the 2025 ESPP, with certain exclusions as determined by the plan administrator.

------

#### **TABLE OF CONTENTS**
However, an employee may not be granted rights to purchase stock under the 2025 ESPP if the employee, immediately after the grant, would own (directly or through attribution) stock possessing 5% or more of the total combined voting power of all classes of our stock. We initially reserved 2,413,854 shares of our Class A common stock for issuance under the 2025 ESPP. The number of shares available for issuance under the 2025 ESPP will be increased annually on January 1 of each calendar year beginning in 2026 and ending and including January 1, 2035, by an amount equal to the lesser of (i) 1% of the shares outstanding on December 31 of the immediately preceding calendar year or (ii) such smaller number of shares as determined by our Board.

We expect to implement our 2025 ESPP in 2026.

#### Equity Compensation Plan Information
The following table provides information as of December 31, 2025, regarding shares of our Common Stock that may be issued under our equity compensation plans, consisting of the 2018 Plan, the 2025 Plan, and the 2025 ESPP.

&nbsp;&nbsp;&nbsp;&nbsp;(1) As of December 31, 2025, the number of shares reserved for issuance under our 2018 Plan, 2025 Plan, and 2025 ESPP were 25,084,129 shares, 36,207,812 shares, and 2,413,854 shares, respectively, subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. The number of shares reserved for issuance under our 2025 Plan automatically increases each January 1, by 5% of the outstanding number of shares of our Class A common stock on the immediately preceding December 31 or such lesser number of shares as determined by our Board. The total number of shares reserved for issuance under the 2025 ESPP automatically increases on January 1 of each of the first 10 calendar years of the 2025 ESPP by a number of shares of our Class A common stock equal to 1% of the total number of shares of our Class A common stock outstanding on December 31 of the preceding calendar year or such lesser number of shares as determined by our Board.

#### CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

#### Policies for Approval of Related Party Transactions
A "Related Party Transaction" is a transaction, arrangement or relationship, or any series of similar transactions, arrangements, or relationships, in which we or any of our subsidiaries was, is or will be a participant, the amount of which involved will or may be expected to exceed $120,000 in any fiscal year, and in which any related person had, has or will have a direct or indirect material interest. A "Related Person" means:

&nbsp;&nbsp;&nbsp;&nbsp;• any person who is, or at any time during the applicable period was, even if such person does not presently serve in that role, one of our executive officers, one of our directors, or one of our nominees for director;

&nbsp;&nbsp;&nbsp;&nbsp;• any person who is known by us to be the beneficial owner of more than 5% of any class of our voting securities;

&nbsp;&nbsp;&nbsp;&nbsp;• any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of a director, director nominee, executive officer or a beneficial owner of more than 5% of any class of our voting securities, and any person (other than a tenant or an employee) sharing the household of such director, executive officer or beneficial owner of more than 5% of any class of our voting securities; and

&nbsp;&nbsp;&nbsp;&nbsp;• any firm, corporation or other entity in which any of the foregoing persons is a director, general partner or principal or in a similar position or in which such person has a 10% or greater beneficial ownership interest.

Our Board has adopted a written Related Party Transactions Policy. Pursuant to this policy, the Audit Committee expects to review all material facts of all Related Party Transactions and either approve or disapprove entry into the Related Party Transaction, subject to certain limited exceptions. In determining whether to approve or disapprove entry into a Related Party Transaction, the Audit Committee expects to take into account, among other factors, the following: (1) whether the Related Party Transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and (2) the extent of the Related Person's interest in the transaction. Further, the policy would require that all Related Party Transactions required to be disclosed in our filings with the SEC be so disclosed in accordance with applicable laws, rules and regulations.

In addition, under our Code of Ethics our employees and directors will have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest.

#### Related Party Transactions
Other than compensation arrangements for our directors and named executive officers, which are described in the section entitled "Executive Compensation", below we describe transactions during the fiscal year ended December 31, 2025 to which we were a participant or will be a participant, in which:

&nbsp;&nbsp;&nbsp;&nbsp;• the amounts involved exceeded or will exceed $120,000; and

&nbsp;&nbsp;&nbsp;&nbsp;• any of our directors, executive officers, or holders of more than 5% of our capital stock, or any member of the immediate family of, or person sharing the household with, the foregoing persons, had or will have a direct or indirect material interest.

#### SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth information about the beneficial ownership of our Class A common stock and Class B common stock as of April 14, 2026 for:

&nbsp;&nbsp;&nbsp;&nbsp;• each person or group known to us who beneficially owns more than 5% of our Class A common stock and Class B common stock;

&nbsp;&nbsp;&nbsp;&nbsp;• each of our directors;

&nbsp;&nbsp;&nbsp;&nbsp;• each of our NEOs; and

&nbsp;&nbsp;&nbsp;&nbsp;• all of our directors and executive officers as a group.

Each stockholder's percentage ownership is based on 221,313,635 shares of Class A common stock outstanding and 8,501,484 shares of Class B common stock outstanding as of April 14, 2026. Beneficial ownership for the purposes of the following table is determined in accordance with the rules and regulations of the SEC. These rules generally provide that a person is the beneficial owner of securities if such person has or shares the power to vote or direct the voting thereof, or to dispose or direct the disposition thereof or has the right to acquire such powers within 60 days. Common Stock subject to options, RSUs, PSUs, or other rights held by such person that are currently exercisable or will become exercisable or will vest within 60 days of April 14, 2026 are deemed to be outstanding and beneficially owned by the person holding the options, RSUs, PSUs, or other rights. These shares, however, are not deemed outstanding for the purposes of computing the percentage ownership of any other person. Except as disclosed in the footnotes to this table and subject to applicable community property laws, we believe that each stockholder identified in the table possesses sole voting and investment power over all Common Stock shown as beneficially owned by the stockholder.

Unless otherwise noted below, the address of each beneficial owner listed on the table is c/o BETA Technologies, Inc., 1150 Airport Drive, South Burlington, VT 05403. Beneficial ownership representing less than 1% is denoted with an asterisk (\*).

#### PROPOSAL 2 — RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee has appointed Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026. Services provided to the Company and its subsidiaries by Deloitte & Touche LLP for the year ended December 31, 2025 are described below and under "Audit Committee Report."

#### Fees and Services
The following table summarizes the aggregate fees for professional audit services and other services rendered by Deloitte & Touche LLP for the years ended December 31, 2025 and 2024:

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024**  |
| **Audit Fees<sup>(1)</sup>** | $2264164 | $322433  |
| **Audit-Related Fees** |  | $15000  |
| **Tax Fees<sup>(2)</sup>** | $571211 | $324248  |
| **All Other Fees<sup>(3)</sup>** | $1895 | $1895 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Audit fees consist of fees and expenses for the annual audit of our consolidated financial statements included in the Annual Report on Form 10-K, the quarterly reviews of our consolidated financial statements included in our Quarterly Report on Form 10-Q, accounting consultations, and services related to other regulatory filings made with the SEC including fees related to the IPO of $750,000 for the year ended December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Tax fees relate to certain tax advisory services.

&nbsp;&nbsp;&nbsp;&nbsp;(3) All other fees consist of access to Deloitte's accounting research tool.

In considering the nature of the services provided by the independent auditor, the Audit Committee determined that such services are compatible with the provision of independent audit services. The Audit Committee discussed these services with the independent auditor and BETA management to determine that they are permitted under the rules and regulations concerning auditor independence promulgated by the SEC to implement the Sarbanes-Oxley Act of 2002, as well as the American Institute of Certified Public Accountants.

The Audit Committee has adopted a policy that requires advance approval of all audit services as well as non-audit services to the extent required by the Exchange Act and the Sarbanes-Oxley Act of 2002. Unless the specific service has been previously pre-approved with respect to that year, the Audit Committee must approve the permitted service before the independent auditor is engaged to perform it. Each year, the Audit Committee will pre-approve an amount for audit services, audit-related services and tax services to be used by the Company's Chief Financial Officer and Chief Accounting Officer, or a designee of the Chief Financial Officer or Chief Accounting Officer, to use for audit projects, which projects require pre-approval by the Audit Committee.

The Audit Committee approved all services provided by Deloitte & Touche LLP. Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting. They will have the opportunity to make a statement if they desire to do so, and we expect that they will be available to respond to questions.

#### Vote Required and Board Recommendation
Assuming a quorum is present, ratification of the appointment of Deloitte & Touche LLP requires affirmative votes from the holders of a majority of the shares present in person or represented by proxy at the Annual Meeting and entitled to vote. If BETA's stockholders do not ratify the appointment of Deloitte & Touche LLP, the Audit Committee will reconsider the appointment and may affirm the appointment or retain another independent accounting firm. Even if the appointment is ratified, the Audit Committee may in the future replace Deloitte & Touche LLP as our independent registered public accounting firm if it is determined that it is in BETA's best interests to do so.

**The Audit Committee and the Board recommend that you vote "FOR" the ratification of the appointment of Deloitte & Touche LLP as the independent registered public accounting firm for the year ending December 31, 2026.**

#### **TABLE OF CONTENTS**

#### AUDIT COMMITTEE REPORT
The Audit Committee is responsible for overseeing the Company's financial reporting process on behalf of the Board. These oversight responsibilities include monitoring the integrity of our financial statements, the Company's independent auditor's qualifications and independence, and the performance of the Company's independent auditor and our internal audit function, and compliance with legal and regulatory requirements.

Management has the primary responsibility for the financial statements and the reporting process, including establishing and maintaining our systems of internal controls over the preparation of the Company's financial statements. The Company's independent registered public accounting firm, Deloitte & Touche LLP, is responsible for performing an audit of the Company's consolidated financial statements in accordance with standards of the Public Company Accounting Oversight Board ("PCAOB") and issuing an opinion on the financial statements.

In fulfilling its oversight responsibilities, the Audit Committee:

&nbsp;&nbsp;&nbsp;&nbsp;• reviewed and discussed the audited consolidated financial statements for the year ended December 31, 2025 with management;

&nbsp;&nbsp;&nbsp;&nbsp;• discussed with our independent auditors, Deloitte & Touche LLP, the matters required to be discussed by the applicable requirements of the PCAOB and the SEC; and

&nbsp;&nbsp;&nbsp;&nbsp;• received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the PCAOB regarding Deloitte & Touche LLP's communications with the Audit Committee concerning independence and has discussed with Deloitte & Touche LLP its independence.

Based on the Audit Committee's reviews and discussions described above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the SEC.

The notice of electronic availability contains instructions on how to access this Proxy Statement and our annual report and vote online. If you received a notice by mail, you will not receive a printed copy of the proxy materials in the mail.

*Householding. The SEC's rules permit us to print an individual's multiple accounts on a single notice or set of annual meeting materials.

We agree to deliver promptly, upon written or oral request, a separate copy of the notice or annual meeting materials, as requested, to any stockholder to which a single copy of those documents was delivered. If you prefer to receive separate copies of the notice or annual meeting materials, contact Broadridge Corporate Issuer Solutions, Inc. at 1-866-540-7095 or in writing at Broadridge Householding Department, 51 Mercedes Way, Edgewood, New York 11717. A number of brokerage firms have instituted householding. They will have their own procedures for stockholders who wish to receive individual copies of the proxy materials.* 

#### Q: Who will be entitled to vote?
Stockholders who own shares of our Common Stock as of the Record Date are entitled to vote at the Annual Meeting. Each share of our Class A common stock entitles its holders to one vote per share on all matters presented to our stockholders generally, and each share of Class B common stock entitles its holders to 40 votes per share on all matters presented to our stockholders generally. As of the Record Date, BETA had approximately 221,313,635 shares of Class A common stock outstanding and approximately 8,501,484 shares of Class B common stock outstanding, representing approximately 39.4% and 60.6% of the total voting power of our Common Stock, respectively.

#### Q: How do I cast my vote?
*Beneficial Stockholders. If you hold your shares through a broker, trustee or other nominee, you are a beneficial stockholder. In order to vote your shares, please refer to the materials forwarded to you by your broker, bank, or other nominee for instructions on how to vote the shares you hold as a beneficial stockholder.* 

*Registered Stockholders. If you hold shares in your own name, you are a registered stockholder and may vote during the virtual Annual Meeting at www.virtualshareholdermeeting.com/BETA2026. You will need your unique control number included on your proxy card or on the voting instructions form that accompany your proxy materials. Only one person will be able to log in with that unique control number at any time. You can also vote by proxy before the Annual Meeting in the following ways:* 

&nbsp;&nbsp;&nbsp;&nbsp;1. via the Internet at www.proxyvote.com;

&nbsp;&nbsp;&nbsp;&nbsp;2. by phone by calling 1-800-690-6903; or

Proxies submitted via the Internet or by telephone must be received by 11:59 p.m. (EDT) on May 28, 2026.

#### Q: Can I access the proxy materials electronically?
Yes. Your notice, proxy card or voting instruction form will contain instructions on how to:

&nbsp;&nbsp;&nbsp;&nbsp;1. view our proxy materials for the Annual Meeting on the Internet; and

Our proxy materials are also available at www.proxyvote.com and our proxy materials will be available during the voting period starting on April 29, 2026.

Instead of receiving future copies of our proxy statement and annual reports by mail, stockholders of record and most beneficial owners can elect to receive an email that will provide an electronic link to these documents.

If you are a stockholder of record as of the Record Date, you may attend, vote and ask questions virtually at the meeting by logging in at www.virtualshareholdermeeting.com/BETA2026 and providing your control number. This number is included in the Notice or on your proxy card.

------

#### **TABLE OF CONTENTS**
If you are a stockholder holding your shares in "street name" as of the Record Date, you may gain access to the meeting by following the instructions in the voting instruction card provided by your broker, bank or other nominee. You may not vote your shares via the Internet at the Annual Meeting unless you receive a valid proxy from your brokerage firm, bank, broker-dealer or other nominee holder. If you are not a stockholder as of the Record Date, you may still listen to the Annual Meeting, but will not be able to ask questions or vote at the meeting.

If you have questions, you may type them into the dialog box provided at any point during the meeting (until the floor is closed to questions).

Recording of the Annual Meeting will not be permitted.

#### Q: Why is the Annual Meeting virtual only?
We believe that a virtual meeting enables increased stockholder attendance and participation because stockholders can participate from any location around the world, while reducing the costs and environmental impact associated with holding an in-person meeting.

#### Q: What is the voting requirement to approve each of the proposals, and how are the votes counted?
*PROPOSAL 1 — ELECTION OF DIRECTORS* 

A plurality of the votes cast by the shares of Common Stock is required to elect each nominee named herein. This means that the three nominees receiving the highest number of votes "FOR" at the Annual Meeting will be elected, even if those votes do not constitute a majority of the votes cast. Votes that are "WITHHELD" with respect to one or more nominees will result in the respective nominee receiving fewer votes, but they will not count as votes against a nominee and will have no effect on the outcome of the election of those nominees because directors are elected by a plurality of the votes cast at the Annual Meeting. If you are a beneficial stockholder, your bank or broker is not permitted to vote your shares on this proposal if voting instructions are not received from you (this is commonly referred to as a "broker non-vote"). Broker non-votes are not considered votes cast and, therefore, will not impact the election of the nominees.

*PROPOSAL 2 — RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM* 

The affirmative vote of a majority of the voting power of the capital stock present in person or represented by proxy at the meeting and entitled to vote thereon is required to approve Proposal 2. Abstentions will be counted as shares present and entitled to vote on Proposal 2 and will therefore have the same effect of a negative vote as a vote against Proposal 2. Since this is a "routine" matter, we do not expect there to be any broker non-votes with respect to the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2026.

#### Q: When will the results of the vote be announced?
The preliminary voting results will be announced at the Annual Meeting. The final voting results will be published in a Current Report on Form 8-K filed with the SEC within four business days of the Annual Meeting.

#### Q: What is the deadline for submitting a stockholder proposal or director nomination for the 2027 Annual Meeting?
Stockholder proposals pursuant to SEC Rule 14a-8 for inclusion in BETA's proxy statement and form of proxy for BETA's 2027 annual meeting of stockholders, to be held in 2027, must be received by BETA at our principal executive offices at 1150 Airport Drive, South Burlington, VT 05403 no later than the close of business on December 30, 2026. Stockholders wishing to make a director nomination or bring a proposal before the annual meeting to be held in 2027 (but not include it in BETA's proxy materials) must provide written notice of such proposal to the Chief Legal Officer and Secretary at BETA's principal executive offices no later than the close of business on March 13, 2027 and not earlier than the close of business on February 11, 2027, assuming BETA does not change the date of the 2027 annual meeting of stockholders by more than 30 days before or after the anniversary of the 2026 Annual Meeting. If so, BETA will release an updated time frame for stockholder proposals. Any stockholder proposal or director nomination must comply with the other provisions of BETA's Bylaws and be submitted in writing to the Secretary at BETA's principal executive offices.
