The persons identified on the cover page hereto (collectively, the “Hartman Group”) on June 3, 2025 filed a definitive proxy statement and an accompanying BLUE universal proxy card with the Securities and Exchange Commission (the “SEC”) to be used to solicit votes for, among other matters, (i) the election of directors that the Hartman Group has nominated for election at the next annual meeting of stockholders of Silver Star Properties REIT, Inc. (the “Company”) and (ii) the rejection of the Company’s alternate strategy proposal, and in favor of liquidating the Company’s assets in an orderly manner in accordance with the terms of its articles of incorporation and returning capital to stockholders.

On June 25, 2025, the Hartman Group distributed the following letter to shareholders. A copy of the referenced letters sent to shareholders in August 2022 and sent to Broker-Dealers and Advisors on June 9, 2025 are attached hereto as Exhibits 99.1 and 99.2 respectively, and are incorporated herein by reference.

SEC FINALLY CAUGHT SILVER STAR

June 25, 2025

Dear Shareholders,

On June 23^rd the Securities and Exchange Commission notified Gerald Haddock and Silver Star Properties REIT that its review of Silver Star’s definitive proxy statement indicates that the proxy statement fails to comply with the requirements of the Securities Exchange Act of 1934, the rules and regulations thereunder and the requirements of the form. You can read SEC’s letter in full here. This would not be the first of Silver Star’s regulatory violations. Silver Star has been recklessly lying and engaging in a smear campaign to hide their irresponsibility as fiduciary to the investor.

Silver Star Engages in Unbridled Disregard For the Law and Regulatory Constraints

· Silver Star has not included audited financial statements with its proxy solicitation, a violation of securities rules and regulations.

· A “Documents and Records” request, required by law, was denied by Silver Star.

· During the current proxy solicitation, Silver Star suddenly alleges victory in the January 2024 Consent Solicitation. There is no record of the Hartman Group revocations having been counted, audited, or factored into their falsified Consent Solicitation results filed with the SEC. For more detail, read the June 9, 2025 letter sent to Broker-Dealers and Advisors.

Disciplined Return of Capital vs. Unrestrained Legal Warfare

I have no vendetta against the Silver Star Executive Board. However, they seem to have one against me. They have as their modus operandi this type of assault to cover their ineffectiveness in creating value to your investment. I proposed in August 2022 a strategic liquidation that would have preserved value. They preferred a takeover and a scorched earth campaign to ensure their entrenchment. Read the letter I sent in August 2022 outlining a disciplined strategy for liquidation that would have preserved shareholder value.

Silver Star In Violation of Proxy Rules

Silver Star continues to amass legal and regulatory violations while they continually and aggressively mount a misinformation and deflection campaign. What arrogance! What hubris! Silver Star is paving their own way for a class action lawsuit against them.

See the attached proxy letter for more details. Click here to read the full letter.

Thank you for your trust and support.

Sincerely,

Al Hartman
