STC Sangoma Technologies Corporation

Sangoma Technologies Corporation (TSX: STC; Nasdaq: SANG) (“Sangoma” or the “Company”), a trusted leader in delivering cloud-based Communications as a Service solutions for companies of all sizes, today announced that on March 28, 2023 it filed a resale registration statement on Form F-3 (the “Resale Registration Statement”) with the Securities and Exchange Commission (the “SEC”) for the registration (the “Share Registration”) of 12,271,637 of its common shares (the “Common Shares”) previously issued or to be issued pursuant to the terms of that certain stock purchase agreement (the “Purchase Agreement”) previously entered into by the Company in connection with the acquisition of StarBlue Inc. on March 31, 2021 (the “StarBlue Acquisition”). A copy of the Resale Registration Statement is available on EDGAR at www.sec.gov.

As partial consideration for the StarBlue Acquisition, the Company previously agreed to issue 15,714,285 Common Shares to the sellers of StarBlue Inc. (the “StarBlue Sellers”), the majority of which was to be issued and distributed in fourteen quarterly installments commencing on April 1, 2022. As of the date hereof, 9,142,856 Common Shares remain to be issued on a quarterly basis, with the final release scheduled for January 2026 (the “Remaining Consideration”). In connection with the Share Registration, the Company has entered into an amendment to the Purchase Agreement (the “Amendment”), effective as of March 27, 2023, which provides that all of the Remaining Consideration shall be issued and distributed to the StarBlue Sellers on the later of (i) the fifth business day following the effective date of the Resale Registration Statement and (ii) such other date as mutually agreed by the Company and the StarBlue Sellers. The Share Registration, Resale Registration Statement and Amendment are each intended to ease administrative burdens in connection with the recurring issuance of the Remaining Consideration and create opportunities for increased liquidity on NASDAQ.

A copy of the Purchase Agreement and the Amendment are each available on EDGAR at www.sec.gov and on SEDAR at www.sedar.com. Following the acceleration of the Common Shares pursuant to the Amendment, there will be no further Common Shares to be issued in connection with the StarBlue Acquisition.

Pursuant to the terms of the Purchase Agreement, approximately 52% of the Remaining Consideration will be issued directly or indirectly to Norm Worthington, and 13% to investment funds affiliated with NewSpring Growth Capital, with which our director Marc Lederman is affiliated. The remainder of the Remaining Consideration will be distributed by Star2Star Holdings, LLC on a pro rata basis to its other members. Due to the tax event triggered by the issuance of shares, Mr. Worthington and Star2Star Holdings, LLC each intend to sell the number of Common Shares necessary to cover their tax obligations. “We believe that accelerating the issuance of Sangoma Common Shares to be contractually issued to the StarBlue Sellers is in the best interests of the Company for a number of reasons, including simplifying the Company’s market capitalization calculation,” said Mr. Worthington. “While I intend to sell a limited number of Common Shares for tax purposes, I anticipate that immediately following such sales I will continue to hold at least 15% of the Common Shares of the Company, and intend to remain a long-term substantial shareholder.” In addition to the Common Shares Mr. Worthington has been and will be issued pursuant to the terms of the Purchase Agreement, Mr. Worthington has purchased an additional 86,900 Common Shares on the open market over the last few weeks, further increasing his ownership in the Company.

The Resale Registration Statement has been filed with the SEC but has not yet become effective. The Common Shares covered by such Registration Statement (the “Securities”) may not be sold, nor may offers to buy any such Securities be accepted, prior to the time the Resale Registration Statement becomes effective by the SEC. If declared effective by the SEC, the StarBlue Sellers may use the prospectus relating to the Resale Registration Statement from time to time to resell their Securities. The Resale Registration Statement is subject to amendment and completion. The Company will not receive any proceeds from the sale of any of the Securities by the StarBlue Sellers. This news release does not constitute an offer to sell or the solicitation of an offer to buy any of the Company’s securities, including the Securities, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
