Pursuant to Rule 425 of the Securities Act of 1933

and deemed filed pursuant to Rule 14a-12

of the Securities Exchange Act of 1934

Subject Company: Nabors Energy Transition Corp.

Commission File No.: 001-41073

Set forth below is an email from Alec Waugh, General Counsel of Vast Solar Pty Ltd (“Vast Solar”), to Vast Solar’s employees and contractors regarding Vast Solar’s proposed business combination with Nabors Energy Transition Corp.

This is a truly exciting opportunity for Vast, Agcentral Energy and the entire extended team.

Taking us from a world of 13 years of private company governance to being listed on the NYSE will be some journey!  It’s a journey we must take over approximately 3 months so this will be quick.  However, the lawyer in me wants to make sure the entire team becomes public company ready understanding how we need to behave and operate in this new environment.  By the way I’m not worried about this as we have some fantastic partners, including the new Nabors team who are excited about working with us.  I know the Vast team can get this done.

The Important Legal Bits

There are some really important steps we must all take to get us ready for this major leap forward.

Moving from a private to public company will be challenging and exciting.  Ensuring we are able to continuously meet all of the legal requirements of operating in the public markets will require us to set up new systems, processes and a governance structure which while being protective remains nimble and agile.

The attached is the starting point with the high level Do’s and Don’ts we must all follow in particular around social media engagements.  Over time this will evolve and develop further.

As soon as Craig is back on the ground we will have a full team update and step out how we prepare for becoming a publicly listed entity.  Craig, Christina, Simon and I can take you through what is required and how we will be getting this done.

Please in the meantime if you have any questions at all on the attached or in general about the transaction I’m available on the phone so just let me know.

What a monster month already!

Cheers

Alec

Do’s & Don’ts

Project Neptune Announcement Social Media Guidelines

As with all public comments surrounding the announcement of a transaction, it is critical to only communicate with nonmaterial and/or publicly available information, such as the Project Neptune initial press release, when posting on social media. This is an exciting transaction for Vast that will help to fuel its growth, and we understand that the company and its employees may want to share this information with their networks.

What follows are recommendations and guidelines for posting to social media, which cover both Vast and its employees.

DOS

• Vast can share the press release across its social channels with a brief post summarizing the news (see sample posts below)

• Vast can share news coverage about the transaction, but only when an article/interview is filed with the SEC with the proper disclaimers

• Employees should feel free to share/repost and like posts that are made by Vast on its Twitter, LinkedIn Instagram, Facebook accounts

• Both the company and its employees should feel comfortable conveying their excitement, but no one should be providing commentary about the deal (e.g., timing for when it will close, what it will mean for the business more generally, etc.)

• Always err on the side of caution. If you are unsure about whether a statement, comment or post is appropriate, please reach out to Alec Waugh (m.[***] e. [***]) or Simon Woods (m.[***] e. [***]) in advance.

DON’Ts

• Do not share any non-public, material information

• Do not share any privileged and confidential communications (e.g., legal advice, internal communications, emails, etc.)

• Do not respond to an inbound request for information or commentary on Project Neptune or Vast without clearing with Craig, Alec or Simon first

• Do not comment on stock price

• Do not talk about your own stock holdings of the company

• Do not comment about the state of the business

• Do not make any forward-looking comments or predictions

• Do not comment about the competition

• Do not share any confidential customer information
