Dear Valued Client,

You might have seen the news this week about Avantax, Inc., the ultimate parent of our broker-dealer and registered investment adviser, entering into a definitive agreement to be acquired by Cetera Holdings.

Avantax and Cetera support firms such as ours by providing technology, service and products to help us deliver comprehensive, tax-inclusive financial services to you. Both Avantax and Cetera offer tools and flexibility to help firms like us run our independent businesses.

The acquisition of Avantax should have very little impact on you – no new paperwork to sign and no immediate change to technology, investment products or the way we service your accounts. In the long-term following the closing, we expect to have enhanced resources that improve your client experience.

Like Avantax, Cetera understands the value of tax-intelligent advice and works specifically with tax professionals to integrate wealth management services into their practices. Upon the closing, we expect our broker-dealer support will be stronger and have a more robust footprint in the tax and accounting sector. Cetera also shares Avantax’s commitment to a strong advisor community that fosters peer learning and collaboration. We’re encouraged that Cetera has indicated that many Avantax programs supporting our growth will continue so we can keep evolving to meet your needs.

The acquisition is expected to close by the end of the year, subject to stockholder approval, regulatory approvals and other customary closing conditions. Overall, we’re excited about the additional resources and scale this deal will afford following the closing, which we believe will allow us to serve you well in the coming years. If you have any questions, please feel free to contact our team.

Sincerely,

[FPC Name]
