Dear Fellow Stockholder,
Sesen Bio’s Board of Directors and management team are focused on enhancing value for all Sesen Bio stockholders. The Sesen Bio Board of Directors unanimously believes the pending merger with Carisma Therapeutics is the most value maximizing option available for Sesen Bio stockholders. Here’s why:
1. Substantial Upfront Cash: The pending merger accelerates the return of direct and immediate cash value through an expected special one-time cash dividend of approximately $70 million, or $0.34 per share1. This dividend is contingent upon closing and represents the cash available in excess of the minimum cash needed to fund the combined company operations.
2. Cutting-Edge Immunotherapy Platform with Upside Opportunity: Stockholders immediately benefit from owning a 25.2% stake, or $0.40 per share2, in the $357 million3 combined company, with potential for significant long-term upside. Carisma’s:
- Proprietary CAR-M platform is an entirely novel immunotherapy approach that has the potential to change the way cancer and other serious diseases are treated;
- First-of-its-kind technology is believed to be the only one with demonstrated proof of mechanism and safety data in clinical trials;
- Strong backing by established investors and strategic partners includes Moderna, Novartis, AbbVie and Merck; and
- Upcoming catalysts and developmental milestones across its clinical programs over the next 18 months provide significant upside opportunity.
3. Additional Potential Cash Upside via a Contingent Value Right: Stockholders will also benefit from any potential proceeds from any sale of Sesen Bio’s legacy assets (including Vicineum) and from the potential $30 million milestone payment, or $0.14 per share4, under the Roche Asset Purchase Agreement.
4. Comprehensive Evaluation of Strategic Alternatives to Maximize Stockholder Value: This attractive transaction is the result of a robust process conducted by the Sesen Bio Board of Directors and management team (with the assistance of independent financial and legal advisors), which included:
- A four-month comprehensive review of strategic alternatives;
- Thorough evaluation of a merger, sale of assets, resumption of R&D and dissolution and liquidation of assets and wind-down of Sesen Bio;
- Outreach to over 100 companies which resulted in 42 bids; and
- Extensive negotiations with Carisma to maximize value in an agreed upon combination.
Beginning in April of 2022, the Sesen Bio Board of Directors and management team conducted an extensive review of strategic alternatives. Based on this review, the Sesen Bio Board of Directors unanimously agreed that the pending merger with Carisma maximized stockholder value over other strategic alternatives, including a potential Nasdaq delisting in January 2023 followed by a dissolution of the company and a liquidation of assets – a path with an inferior distribution of cash, additional risk from needing to satisfy contingent liabilities and a prolonged timeline leading to additional cash burn. The Board remains fully committed to the pending merger with Carisma, which it continues to believe maximizes value for all stockholders.
The Sesen Bio Board of Directors would like to take this opportunity to clarify a number of supposed issues surrounding this transaction, so that stockholders can more accurately evaluate the pending merger.
Did Sesen Bio negotiate to fully maximize the value to stockholders in this transaction?
Yes. The pending merger with Carisma is the result of a comprehensive strategic review process with bids from 42 different companies, as well as extensive negotiations with Carisma. Further, following the announcement of the pending transaction in September 2022, Sesen Bio has engaged extensively with its stockholders and Carisma to explore ways to deliver significant value in connection with the pending transaction. Based on feedback from Sesen Bio stockholders, in December 2022, Sesen Bio and Carisma agreed to amend the merger agreement to do just that:
- Increased expected special cash dividend to be paid to Sesen Bio stockholders from the previously stated up to $25 million to an expected approximate $70 million, representing the amount of excess cash Sesen Bio will have available after meeting a required net cash minimum of $75 million; and
- Expanded the CVR to include potential proceeds from any sale of Sesen Bio’s legacy assets, including Vicineum.
The increased expected special cash dividend and expanded CVR, coupled with an ownership position in a combined company poised for significant long-term upside, is expected to deliver an implied total value of $0.88 per share5 that could otherwise not be achieved.
Could Sesen Bio dividend its remaining cash as suggested by the Investor Group and then find another alternative (i.e., dissolve the Company)?
No. Sesen Bio and Carisma and their respective advisors have engaged extensively with Bradley Radoff and Michael Torok and their affiliates (collectively, the “Investor Group”) in an attempt to reach an amicable resolution regarding the pending merger. Despite Sesen Bio’s best efforts to be flexible and transparent, the Investor Group has increased its opportunistic position in Sesen Bio stock and remains focused on an unfeasible distribution scenario with inaccurate assumptions that would leave considerable stockholder value on the table.
Without the pending merger with Carisma, the most likely and feasible path would be an exchange delisting (as previously publicly communicated) followed by a dissolution of the Company and a liquidation of assets.
The Investor Group has not considered or has chosen to ignore these facts. In a more realistic orderly dissolution and liquidation scenario – which would come with significant expense, delay and uncertainty – only approximately 60%-90%6 of Sesen Bio’s cash balance, or approximately $0.40-$0.60 per share7, would be available for an initial distribution to stockholders, and that could take up to six months or more after an additional stockholder vote to approve the dissolution and liquidation. The remaining amount would fund the wind-down of operations and the reserves for current, potential future and unknown liabilities, which could take up to three years to fully settle.
Is Carisma the best merger candidate for Sesen Bio?
Yes. The Sesen Bio Board of Directors, in consultation with its financial and legal advisors, carefully evaluated 42 bids over several months before determining that a transaction with Carisma was the most value maximizing opportunity.
- Carisma is revolutionizing the field of immunotherapy with cutting-edge technology to develop first-of-their-kind engineered macrophages.
- CAR-M technology has the potential to address a large patient population with broad applicability across multiple types of solid tumors, including non-oncology applications such as liver fibrosis and autoimmune and neurodegenerative disease indications.
- Carisma’s strategic collaboration with Moderna will fully fund R&D of innovative potential cancer therapies and provides potentially significant downstream economics in the form of development, regulatory and commercial milestones, in addition to royalty payments.
Furthermore, the combined company will be led by Carisma’s experienced Board and management team, which has strong investor support including from AbbVie, Moderna, Wellington and TPG:
- CEO Steven Kelly was recently named Ernst & Young Entrepreneur of the Year 2022 Greater Philadelphia, an award that recognizes the most ambitious leaders who are building and sustaining successful, dynamic businesses around the world.
- Co-founder and Chief Scientific Officer Dr. Michael Klichinsky co-invented the technology at the University of Pennsylvania.
The Sesen Bio Board of Directors unanimously urges you to vote FOR the pending merger TODAY to ensure you receive the maximum value of your shares.
The Sesen Bio Board of Directors unanimously recommends stockholders vote “FOR”:
- Proposal No. 1: Approval, for purposes of Nasdaq Listing Rule 5635(a) and (b), of the issuance of shares of Sesen Bio common stock to Carisma stockholders pursuant to the terms of the Merger Agreement and the change of control of Sesen Bio resulting from the merger
- Proposal No. 2: Approval of an amendment to the Sesen Bio Certificate of Incorporation to effect the reverse stock split and reduce the number of authorized shares of Sesen Bio common stock
- Proposal No. 3: Approval of an amendment and restatement of the 2014 Incentive Plan
- Proposal No. 4: Approval of an amendment to the 2014 ESPP
- Proposal No. 5: Approval of an adjournment of the Sesen Bio special meeting, if necessary, to solicit additional proxies
The pending merger is expected to close in the first quarter of 2023, subject to approval by Sesen Bio’s stockholders and other customary closing conditions.

About Sesen Bio
Sesen Bio, Inc. is a late-stage clinical company that was previously focused on targeted fusion protein therapeutics for the treatment of patients with cancer. Sesen Bio’s most advanced product candidate, Vicineum™, also known as VB4-845, is a locally-administered targeted fusion protein composed of an anti-epithelial cell adhesion molecule antibody fragment tethered to a truncated form of Pseudomonas exotoxin A for the treatment of non-muscle invasive bladder cancer. On July 15, 2022, Sesen Bio made the strategic decision to voluntarily pause further development of Vicineum in the US. The decision was based on a thorough reassessment of Vicineum, which included the incremental development timeline and associated costs for an additional Phase 3 clinical trial, following Sesen Bio’s discussions with the United States Food and Drug Administration. Sesen Bio has turned its primary focus to consummating the pending merger with Carisma Therapeutics, Inc. with the goal of maximizing stockholder value. Additionally, Sesen Bio is seeking a partner for the further development of Vicineum. For more information, please visit the Company’s website at www.sesenbio.com.
