Investcorp AI Acquisition Corp. Announces Entry into Business Combination Agreement and Scheme Implementation Deed with Bigtincan

NEW YORK, October 21, 2024 – Investcorp AI Acquisition Corp. (“IAAC”) (Nasdaq: IVCA)¹ is pleased to announce that it has agreed to terms with Bigtincan Holdings Limited (“Bigtincan”) (ASX:BTH) under which, if implemented, IAAC would combine with Bigtincan’s business and list on the Nasdaq through a newly formed Cayman Islands exempted company called “Bigtincan Limited” (the “Transaction”).

Transaction Highlights

Harsh Shethia, a 22-year veteran of Investcorp and advisor to IAAC said: “This transaction offers tremendous value not just for Bigtincan’s shareholders, but also for its customers, employees, and partners. It’s a chance to showcase Australia’s strength in AI innovation, especially in sectors like sales enablement, and position an Australian-born company as a global leader in enterprise software. We’re excited to help Bigtincan take the next step in its journey.”

Transaction Overview

Under the Business Combination Agreement (“BCA”), scheme implementation deed (“SID”) and related Transaction documents:

Bigtincan shareholders will receive 1 Bigtincan Limited share for every 30.97 Bigtincan shares held in the Transaction, with the result that Bigtincan shareholders will own up to ~75%¹⁰ of Bigtincan ordinary shares immediately following the closing of the Transaction.

A partial cash election facility may be established, under which Bigtincan shareholders may elect to receive cash consideration for their shares of US$0.16145 (~A$0.241¹¹) per Bigtincan share, subject to availability of funds and a scale back mechanism. If activated, Bigtincan shareholders on the register as of 12:01am today will be given preferential access for their first 5,000 shares under the cash election facility (meaning those shareholders will be entitled to receive the cash scheme consideration on those shares before any pro-rata scale back is applied).

Investcorp will invest US$12.5m (~A$18.7m¹²) into Bigtincan Limited as part of the Transaction, the proceeds of which will be used to fund the partial cash election facility. If additional funds can be secured which, together with the foregoing PIPE by Investcorp, aggregate to at least USD$15m, the partial cash election facility will be activated.

In addition, Bigtincan Limited will seek to raise up to US$25.0m (~A$37.3m¹³) of PIPE from institutional investors and up to US$25m of debt financing to support the Transaction.

Implementation of the Transaction under the Transaction Documents is subject to the satisfaction (or, where applicable, waiver) of various conditions precedent, including:

The SID contains reciprocal customary exclusivity provisions (including ‘no-shop’, ‘no-talk’ and due diligence restrictions, and a notification obligation). IAAC also has a matching right.

No break fee is payable by Bigtincan to IAAC (and vice versa) if the AGM Resolution is not passed and the Transaction Documents are terminated. If the AGM Resolution is passed, then Bigtincan and IAAC may each be liable to pay a break fee to the other of US$2.75 million in the circumstances outlined in the SID.

Approval of the AGM Resolution does not mean the Transaction will occur as it will remain subject to other conditions precedent, including approval by Bigtincan shareholders at a subsequent scheme meeting.

Unanimous Recommendation of the Directors

The board of directors of IAAC considers entry into the BCA and the SID to be in the best interests of IAAC’s shareholders and unanimously recommends that IAAC’s shareholders vote in favor of the Transaction.

Indicative Timing and Next Steps

IAAC shareholders do not need to take any action at this stage.

A registration statement on Form F-4 of Bigtincan Limited (the “Registration Statement”) will be filed with the U.S. Securities and Exchange Commission (the “SEC”), which will contain a proxy statement of IAAC to solicit IAAC shareholder approval at an extraordinary general meeting of IAAC shareholders and a prospectus of Bigtincan Limited to register the Bigtincan Limited shares to be issued in connection with the Transaction. Once the SEC has declared the Registration Statement effective, it will be promptly mailed to IAAC’s shareholders, along with a proxy card for each IAAC shareholder entitled to vote at the extraordinary general meeting.
