The Board of Directors (the “Board”) of SolarWindow Technologies, Inc. (the “Company”) appointed Francisco Javier Bono Perez to the Board effective as of November 20, 2025.

Mr. Bono currently serves as President of International Development at Landvac Ti-Vacuum Insulated Glazing (July 2025 – present) located in Luoyang, Henan, China and has been employed as an independent contractor by LandGlass Technology Co., Ltd. for more than 11 years, the last 7 years as its Vice President of International Development. Prior thereto Mr. Bono was employed at Suministros Aries, S.L., a Spanish company located in Valencia, Spain for more than 13 years, the last 4 years and 8 months as its Chief Executive Officer.

Mr. Bono received a Bachelor of Science (B.S.), Mechanical Engineering, from Lafayette College in 2000. He also received an Executive MBA from the IESE Business School in 2009. Mr. Bono participated in certification programs at the Harvard Business School (Executive Education) in 2018, and the China Europe International Business School (International Business, as part of his Executive MBA) in 2009.

The Company believes that Mr. Bono’s nearly 25 years of experience in all types of glass-related industries and his global reach across the glass industry, including solar, architectural, automotive, and specialty fabricated glass, not only make him a valuable asset for the Company but also qualifies him for membership on the Board.

There are no family relationships existing between Mr. Bono and any director or executive officer of the Company. There have been no transactions, and no transactions are currently proposed, in which the Company was or is to be a participant and in which Mr. Bono or any member of his immediate family had or will have any interest, that are required to be disclosed by Item 404(a) of Regulation S-K. In addition, there are no arrangements or understandings between Mr. Bono and any other persons pursuant to which Mr. Bono was appointed to the position as a member of the board. Prior to his appointment to the Board, Mr. Bono’s served on the Company’s Board of Advisors since July 2019.

Silica Holding B.V. (“Silica”) is a foreign corporation domiciled in the Netherlands and wholly owned Silica Ventures, S.L., a Spanish company, and are each wholly owned by Mr. Bono, who has subscribed for and purchased, in the Company’s June 2025 offshore private placement, for an aggregate price of $1,000,000, a total of 3,225,806 units of the Company’s securities, each unit consisting of one share of common stock and one warrant to purchase an additional share of the Company’s common stock at an exercise price of $0.47 per share (collectively, the “Private Placement Securities”). Silica’s ownership of the Private Placement Securities represents, on a fully diluted basis, a beneficial interest of 9.35% in the Company’s issued and outstanding common stock as to which Mr. Bono has voting and disposition authority.

Mr. Bono’s relationship with Company will be governed by, subject to applicable law, Offer Letter dated November 20, 2025 between the Company and Mr. Bono (the “Offer Letter”). A copy of the Offer Letter is attached hereto as Exhibit 10.1 to this Current Report on Form 8-K. Mr. Bono has waived all compensation otherwise payable to him as a member of the Company’s Board of Directors. In addition, Mr. Bono, as a condition to his appointment to the Board of Directors, executed the Company’s standard confidential information and invention assignment agreement.
