Exhibit 99.1

GigInternational1 and Convalt Energy Sign an Exclusive Term Sheet for a Business Combination

Company expected to be public in the first half of 2023

Palo Alto, Calif. & Watertown, NY – August 30, 2022 – GigInternational1, Inc. (Nasdaq: GIW), a publicly traded special purpose acquisition company, and Convalt Energy, Inc. (“Convalt”) announced today that they have entered into a non-binding term sheet, with the goal of completing a business combination resulting in Convalt becoming a publicly traded renewable, manufacturing and power generating company.

Convalt is a vertically integrated renewable energy company in the business of manufacturing solar panels, generating renewable power at company-owned power generation facilities, and providing engineering & construction services including solar panel recycling for renewable energy projects. In 2021, Convalt purchased the manufacturing assets of SunPower Corporation and relocated the automated assembly lines from Hillsboro, Oregon to Watertown, New York, where a new factory capable of producing up to 900 MW of solar panels is expected to be operational in the third quarter of 2023. With significant local community and political and financial support from Jefferson County and the State of New York and now with the Inflation Reduction Act bill, Convalt has invested in power generation projects in upstate New York and Maine and expects these assets to provide clean, renewable power to the local communities and the electric grid by year end 2023. Convalt’s engineering and construction division currently engages in build-outs of power generation facilities for corporate and utility customers. Convalt expects to employ about 400 people including former military personnel especially from the nearby Fort Drum Army Reserve.

Hari Achuthan, Founder, Chairman and Chief Executive Officer of Convalt, commented: “Our core mission is to deliver clean and affordable energy to consumers, responsibly and innovatively, as we also create jobs in New York State and Maine. Convalt is dedicated to bringing the manufacturing of the critical components of the solar supply chain back to American soil prior to December 2024. This combination and partnership with GigInternational1 will allow us to further deliver on our mission, accelerate our growth, and provide significant shareholder value as a public company.”

Dr. Raluca Dinu, Founding Managing Partner of GigCapital Global and CEO of GigInternational1, commented: “We incepted GigCapital Global in 2017 as a lead sponsor of technology Private-to-Public Equity (PPE) TMT companies, also known as special purpose acquisition companies (SPAC), driven by the purpose of bettering our world and making our planet cleaner and

sustainable for generations to come. We are delighted to partner with Convalt on its journey to the public market, as it represents a timely investment opportunity in the development of clean energy in the United States. Hari and the Convalt team have established a business with strong fundamentals and with the ability to scale manufacturing, power generation and a construction business into a fully-integrated renewable energy company, with strong support and incentives from local, state governments in New York and Maine and from the federal government via the Inflation Reduction Act. We are incredibly excited about Convalt’s purpose and mission, proven track record and global growth opportunity and becoming a top tier vertically integrated renewable power company. We look forward to supporting their transition to a public company and beyond.”
