FOR IMMEDIATE RELEASE

MainStreetChamber Holdings (OTC: MSCH) Clarifies Kathy Ireland Relationship, Addresses Industry Coverage, and Advances Strategic Growth Initiative

Las Vegas, NV — March 18, 2026 — MainStreetChamber Holdings, Inc. (OTC: MSCH) today issued a formal statement clarifying its historical relationship with Kathy Ireland Worldwide (kiWW) and addressing recent industry coverage, while highlighting the Company’s continued strategic momentum. Following a period of contractual restructuring and evolving developments within the kiWW organization, MSCH has taken steps to ensure transparency, provide additional context to the public record, and position the Company for long-term growth through a focused operating model and a series of strategic acquisitions scheduled to close on April 1, 2026.

Clarification of Company Structure and Historical Relationship

MSCH is a publicly traded holding company, not an investment firm.

Beginning in 2023, MSCH, through its wholly owned subsidiary Advanced Licensing, entered into a series of licensing and sublicensing agreements with kiWW. As part of that relationship, MSCH pursued the development of a broader licensing platform associated with the Kathy Ireland brand, including a temporary corporate name change in 2024 from MainStreetChamber Holdings, Inc. to Kathy Ireland Licensing, Inc.

Prior to any corresponding ticker symbol change, MSCH was informed that Kathy Ireland intended to separate from her business partners. In response, MSCH cooperated and discontinued use of the Kathy Ireland Licensing name and subsequently worked over an approximately 12-month period to negotiate a new agreement with Kathy Ireland, LLC, which was executed on October 8, 2025.

At no time did MSCH hold any shares in, have control over, or participate in the internal financial management, capital structure, or governance of Kathy Ireland Worldwide.

Clarification Regarding Licensing International Article

MSCH appreciates the coverage by Licensing International and recognizes that the complexity of multi-year licensing and sublicensing agreements, combined with publication timing constraints, may have contributed to certain inaccuracies or lack of context.

To ensure clarity, the Company provides the following corrections:

Statement: MSCH was described as an “investment and licensing firm” operating under the symbol MSC
Clarification: MSCH is a publicly traded holding company with the ticker symbol MSCH

Statement: Kathy Ireland Worldwide owned 20% of MSCH and “surrendered” its shares under a new contract
Clarification: Shares which were allocated to Kathy Ireland have been returned as part of the new agreement, while MSCH is currently in discussions with other kiWW-affiliated entities, which has been very cooopertive throughout this process and finalizing an additional return of shares.

Statement: MSCH discontinued a “Kathy Ireland Laundry laundromat business”
Clarification: The business originated as Aloha Laundry and was rebranded as Kathy Ireland Laundry in 2023. It is not a laundromat business, and the Company is currently evaluating potential rebranding strategies

Statement: MSCH represents Bo Derek for licensing
Clarification: MSCH does not represent Bo Derek. Rather, MSCH, through its wholly owned subsidiary Advanced Licensing, participates in a joint venture partnership involving licensing and product development, of the Perfect 10 Mattress & Furniture brand

Statement: MSCH has “parted ways” with Kathy Ireland Worldwide
Clarification: MSCH maintains contractual rights to license the Kathy Ireland brand across multiple verticals and may elect to continue utilizing the brand in certain categories

Statement: “We have been in a holding pattern for everything…”
Clarification: During an approximately 12-month period of contract restructuring, the Company experienced a limbo period and sales suffered. With subsequent developments, including Kathy Ireland’s separation from kiWW, MSCH is now well-positioned to advance its growth strategy

Strategic Direction and Growth Initiatives

While the restructuring process created temporary delays, MSCH believes it has emerged stronger and well-positioned to expand its portfolio.

MSCH has entered into agreements to acquire a diversified group of operating companies, with anticipated closings on April 1, 2026:

• Final Mile Technologies

• KozyFurniture

• Perfect Dreamer Mattress

• Aloha Laundry

• Chamber Financial Services

• Chamber Insurance Agency

• Diamond Broker USA

• Perfect 10 Mattress

These acquisitions are expected to enhance the Company’s integrated platform, expand recurring revenue opportunities, and support long-term scalability.
