On January 6, 2025, Metroplex Trading Company, LLC (doing business as GrabAGun), which is party to a previously disclosed Business Combination Agreement, dated as of January 6, 2025, with Colombier Acquisition Corp. II, among other parties, distributed the following message to its existing vendors and business partners.

Hi [NAME]

I am thrilled to share with you that GrabAGun has taken a significant step forward as the leading digital platform focused on shooting sports.

This morning, we announced a definitive agreement for a transaction that when completed will result in GrabAGun becoming a publicly traded company. We've signed this agreement with Colombier Acquisition Corp. II (NYSE: CLBR), a special purpose acquisition company led by Omeed Malik.

We expect to close the business combination in the summer of 2025. Once the transaction is completed, we expect GrabAGun will be listed on the NYSE under the symbol "PEW".

We've made significant progress over the past few years in becoming an established market leader in the rapidly expanding multi-billion-dollar online firearm and ammunition industry. The business combination with an exceptional partner in Colombier will be transformative and continue supporting GrabAGun's growth strategy, enabling us to expand our reach and improve customer experiences.

As far as our working relationship is concerned, business is as usual. We would not have been able to take this step without your continued support, so from our entire team, I would like to thank you for the opportunities you have provided. Because of your trust in our team and our mission, we believe the future is bright for our company and for the future of this industry. We look forward to continuing this journey together.

Sincerely,

Marc
