Investor Update 4/16 – Huge Updates Before Start Engine Offering Close

Dear Investors and Friends,

Over the last few weeks, we have made progress on partnerships and project discussions that we believe could support our goal of achieving certification and pursuing pilot installations as early as 2027.

Like an orchard after a long growing season, everything we’ve been nurturing seems to be ripening at once. Now we will harvest the bounty and bring Wind Harvesters© to the world.

In the meanwhile, our Start Engine offering closes at midnight this Friday, April 17. If you have friends who’ve been watching Wind Harvest from the sidelines, now is the time to alert them.

Chair Capital MOU: Potential pathway toward TRL 9 and project finance readiness (subject to milestones and third-party requirements)

The best news for potential investors is that big money with significant experience in commercializing new renewable energy technologies is serious about investing in Wind Harvest.  We’ve entered a Memorandum of Understanding with Chair Capital, a London and Dubai based investment firm focused on energy transition, data infrastructure, and AI. The MOU outlines a potential capital structure of up to USD 80M+ across three milestone-based tranches, subject to further due diligence and definitive agreements. If completed, this structure is intended to support Wind Harvest’s progression toward TRL 9 (full commercial certification) and may help facilitate project financing for customers.

Chair Capital is conducting due diligence and we are discussing a potential Series B; timing and completion are subject to due diligence, negotiation of definitive documents, and other conditions. Their funding is released when the Wind Harvester achieves third-party validation of power performance.  This is expected in the fall of 2026.  At that point Chair’s capital will finance projects ready to order our turbines.

Patent Number 9 – International Protection

Large extruded aluminum blades are key to VAWT longevity and capacity to withstand turbulence.  Almost two years ago, we ordered the largest blade extrusion die that Step-G could make. They then produced sample sections that looked great but when they extruded the full blade, the “skin” sagged on the trailing edge. Our engineers found an innovative and simple way to solve that manufacturing problem and in the process, devised a patent that we think will make it impossible for others to make large aluminum blades for VAWTs without licensing our U.S. Patent No. 12,595,781 B1.

We plan to secure international protection of this patent in all countries with significant wind farm capacity that can add VAWTs to their understories.

LOI Signed: Port Hamilton Refining and Transportation — Coke Dock Peninsula

We signed a non-binding Letter of Intent with Port Hamilton Refining and Transportation (PHRT) for the Coke Dock Peninsula project in St. Croix, U.S. Virgin Islands. This formalizes PHRT as the offtaker — the purchaser of the electricity — for what we envision as a landmark wind-solar hybrid project on the peninsula, with up to 120 Wind Harvesters (6 MWs) and 6–7 MWs of solar panels installed between the turbine rows.

To prepare for the LOI, Wind Harvest completed Phase I wildlife field observations, made leadership site visits, did environmental scoping, and completed months of legal and leasing work.

LOI Signing at RES 2026: Cheyenne and Arapaho Tribes — Concho Casino Project

The Cheyenne and Arapaho Tribes represented by Governor Reggie Wassana, signed a non-binding LOI with Wind Harvest at the Reservation Economic Summit (RES 2026).  The LOI sets the stage for the Wind Harvester certification project at the Lucky Star Casino near Concho, Oklahoma, with the opportunity to potentially sell many more turbines to projects on their reservation. Starting with the Casino project, the tribe will help Wind Harvest collect the bird and turbine wake impact data needed for larger project permitting and safe integration under other wind energy technologies.

You will gain an understanding of how Wind Harvester and solar tracker systems can work on the same ground and accommodate bison grazing beneath from this video and graphical rendering. The site is a few hundred meters to the east of the casino.

New Team Members Breaking New Ground

You might know about  two exceptional people we recently hired from past updates. Pronita Saxena joined as Wind Harvest’s Chief Development Officer. Nathan Hart with the Cheyenne and Arapaho Tribes is now focused on working with Wind Harvest. With the help of Investment Tax Credit (ITC) tax attorneys Phyllis Guillory and Mark Reidy with Womble Bond and Dickinson, Pronita, Nathan and our team and partners have found a new and simple way for tribes to meet the July 4, 2026 deadline for “breaking ground” to lock in the 50% Investment Tax Credit “Safe Harbor” on large and small wind and solar projects that will be on line on or before the end of 2030.

A key to meeting the deadline is for projects to uphold tribal principles and priority goals. Short turbines like Wind Harvesters may help address the unity problem that tall traditional turbines create. Many tribal members want the income that the turbines produce while others don’t want to see the tall turbines and worry about their impacts on eagles.  Tribes may be better able to reach consensus by considering wind technology with a lower visual profile, such as Wind Harvesters’ turbine designs. Wind Harvesters’ technology is also being evaluated for potential benefits to wildlife. As a result, Nathan and Pronita are in ongoing discussions with several tribes in wind-rich regions including WY, MT, ND, SD, NM, OK, and CA.

We appreciate support in financial or other forms. With favorable conditions, we aim to help tribes pursue opportunities to access potential federal funding for renewable energy projects that tribes may own and benefit from over time.

Turbine Components: Parts in Motion

We have concrete progress to report on the physical components for the Concho casino project.

Product is in development and has not been manufactured or commercially launched. Design, specifications, and availability are subject to change.

• Driveshafts scheduled to ship soon: The driveshafts manufactured by Tech-Max Machine in Illinois to Action Machine in Indiana for driveshaft assembly, which includes the installation of Schaeffler bearing and the top tower plate. The completed driveshaft assemblies will ship directly to the Concho Casino site, where they will be ready for installation at the top of the lattice tower during the M4.0 turbine installation, consistent with the process used for the Model 3.1 assembly.
• StepG blades paid for and shipping: Ten StepG blades — the extruded aircraft aluminum design that improves performance and fatigue life — have been ordered and are being shipped from Germany to the site.
• Two Permanent Magnet Generators (PMG) paid for: Both PMGs for the Wind Harvester 4.0s have been ordered and will be shipping from Soga in Italy to Concho soon.

We are beginning to see hardware progress toward a project site that is supported by a letter of intent, with discussions underway with a potential offtaker and tribal ownership considerations at the center of the project. This reflects an early-stage example of how the commercialization process may develop.

As the current offering period progresses, we welcome additional investor interest in the Start Engine campaign. Investors are encouraged to share information about the offering, which we anticipate may be among the final crowdfunding opportunities available to participate at this stage. This represents an opportunity to invest in an early-stage technology addressing new markets in renewable energy, prior to potential future financing events and revenue generation.

Thank you, as always, for your belief in Wind Harvest and in the team bringing it to market.

With appreciation,

Kevin Wolf

CEO & Co-Founder, Wind Harvest International
