Combined company expected to have at least $40 million in cash prior to closingSpring Bank stockholders to receive two separate contingent value rights related to Spring Bank’s STING agonist and STING antagonist programsCompanies to host joint conference call on July 30, 2020 at 7:30 a.m. Eastern TimeHOPKINTON, Mass. and CAMBRIDGE, United Kingdom and CAMBRIDGE, Mass., July 29, 2020 (GLOBE NEWSWIRE) — Spring Bank Pharmaceuticals, Inc. (Nasdaq: SBPH) (“Spring Bank”), a clinical-stage biopharmaceutical company developing novel therapeutics for oncology and inflammatory diseases, and F-star Therapeutics, Limited (“F-star”), a privately-held clinical-stage biopharmaceutical company focused on transforming the lives of patients with cancer through the development of innovative tetravalent bispecific (mAb2™) antibodies, today announced that the companies have entered into a definitive share exchange agreement pursuant to which Spring Bank will, subject to stockholder approval, acquire all of the outstanding share capital of F-star in exchange for newly issued shares of Spring Bank in an all-stock transaction. The combined company, operating under the name F-star Therapeutics, Inc., will advance its immuno-oncology pipeline of multiple tetravalent bispecific antibody programs, as well as Spring Bank’s STING (STimulator of INterferon Gene) agonist, SB 11285, currently in a Phase 1/2 clinical trial.Martin Driscoll, President and CEO of Spring Bank, said: “After an extensive and thorough review of Spring Bank’s strategic options following the termination of our Phase 2b Hepatitis B development program earlier this year, we are thrilled to announce a proposed combination with F-star Therapeutics. We believe the combined company’s strong portfolio of multiple clinical-stage immuno-oncology therapeutic programs, near-term milestones, and accomplished oncology development leadership team offer an excellent opportunity to benefit cancer patients, as well as provide the potential for future value creation for Spring Bank stockholders. The F-star leadership team has committed to continuing the ongoing clinical trial of SB 11285, an IV-administered STING agonist, as part of its expansive immuno-oncology clinical pipeline.“This transaction offers the Spring Bank stockholders of record as of immediately prior to the close of the combination potential future additional value in the form of two contingent value rights (“CVRs”) related to our STING agonist and STING antagonist programs. The first CVR represents the right to receive a potential future cash payment of at least $1.00 per share (on a pre-reverse split basis) if the combined company consummates one or more strategic transactions for SB 11285 aggregating at least approximately $18.0 million within a certain period following the closing. The second CVR gives Spring Bank stockholders the right to receive 80% of the net proceeds from a potential development agreement and from one or more strategic transactions related to the STING antagonist research program that are consummated within a certain period following the closing of the combination.”Eliot Forster, CEO of F-star, said: “We are truly excited about the opportunity created by this proposed combination to further advance our pipeline of novel tetravalent bispecific antibodies, which we believe will be able to address the limitations of current therapies in the field of immuno-oncology. At F-star, we are pioneering a differentiated approach to bispecifics, using a natural human IgG1 antibody format that has already shown early signs of clinical activity, established manufacturing processes and promising safety.“Currently, only a minority of patients realize long-lasting benefit from immunotherapy, so there remains a significant unmet medical need to develop more effective cancer treatment options. We believe this transaction will provide the resources to accelerate F-star’s clinical development and generate stockholder value through a pipeline of novel therapies with the potential to improve the lives of patients with difficult to treat cancers.”By developing medicines that seek to block tumor immune evasion, F-star’s goal is to offer patients greater and more durable benefits than current immuno-oncology treatments. Through its proprietary tetravalent, bispecific antibody (mAb²) format, F-star’s mission is to generate highly differentiated, best-in-class drug candidates with monoclonal antibody-like manufacturability.The combined company’s pipeline will include:FS118, a LAG-3/PD-L1-targeting tetravalent bispecific antibody, currently in Phase 1 developmentFS120, a Phase 1-ready dual T cell agonist tetravalent bispecific antibody targeting OX40 and CD137FS222, a conditional agonist targeting CD137 and PD-L1 expected to enter first in human trials in the first quarter of 2021SB 11285, a novel IV-administered STING agonist, currently in a Phase 1/2 clinical trial for the treatment of solid tumorsAdditional research programs from the F-star differentiated bispecific technology platform and the potential further development of Spring Bank’s STING agonist antibody drug conjugates (“ADCs”)The combined company plans to advance its pipeline through multiple clinical trials, including the following anticipated near-term milestones that offer significant potential value creation for Spring Bank’s stockholders:Report Phase 1 results from the FS118 program (2020 Q4)Update on SB 11285 monotherapy cohorts (2020 Q4)Update on accelerated dose titration from the FS120 Phase 1 trial (2021 Q2)Initial read out from the SB 11285-atezolizumab combination cohort (2021 H1)Initiation of PK/PD expansion cohorts in the FS222 Phase 1 trial (2021 Q4)Update on FS118 Phase 2 proof of concept trial (2022 Q1)Initiation of FS120 PD-1 combination trial (2022 Q2) Update on dose escalation in FS222 Phase 1 (2022 Q2)Report FS118 Phase 2 proof of concept readout (2022 Q4)Report initiation of tumor specific expansion cohorts in FS222 Phase 1 (2022 Q4)F-star anticipates raising additional capital at the closing of the proposed combination from current and potential new investors and the combined company expects to have at least $40 million in cash prior to closing. This financing will help fund the further development of the combined company’s preclinical and clinical immuno-oncology programs, and the combined company expects to have multiple opportunities to raise non-dilutive capital from existing and future business development collaborations over the next two to three years.About the Proposed Combination
Pursuant to the share exchange agreement, Spring Bank will acquire all of the outstanding share capital of F-star in exchange for the issuance of newly issued shares of Spring Bank common stock upon closing, subject to the satisfaction or waiver of customary closing conditions, including the receipt of the required approval of the Spring Bank stockholders. On a pro forma basis and assuming that the proceeds of the concurrent F-star financing will be $25 million, current Spring Bank equity holders and F-star equity holders will own approximately 38.8% and 61.2%, respectively, of the combined company calculated on a fully diluted basis using the treasury stock method and, in the case of Spring Bank, excluding out-of-the-money options and warrants. The actual ownership allocation will be subject to adjustment based on Spring Bank’s net cash balance at the closing of the transaction, the actual amount raised in the F-star financing and certain other terms set forth in the share exchange agreement. Prior to closing, Spring Bank will seek stockholder approval to effect a reverse stock split of its outstanding common stock so that the combined company satisfies the continued listing requirements of the Nasdaq Capital Market.In addition to retaining equity ownership of the combined company, Spring Bank stockholders of record as of the close of the combination will have the opportunity to obtain potential future value in the form of two CVRs associated with Spring Bank’s ongoing Spring Bank SB 11285 IV clinical program and Spring Bank’s STING antagonist research platform. Subject to the terms of the first CVR agreement for the STING agonist clinical program, if one or more strategic transactions are consummated for SB 11285 by the combined company during a period that is the longer of one and a half years following the closing of the combination or one year after the final database lock of the current SB 11285 IV Phase 1a/1b trial, those equity holders of Spring Bank will receive the greater of 25% of the net proceeds from such transactions or $1.00 per share (on a pre-reverse split basis), provided that the aggregate net proceeds are at least approximately $18.0 million. Subject to the terms of the second CVR agreement, if a potential development agreement is consummated and one or more strategic transactions are consummated for the STING antagonist research platform by the combined company during the seven (7)-year period following the closing of the combination, those equity holders of Spring Bank will receive 80% of the net proceeds from such transactions. If Spring Bank enters into a development agreement for the STING antagonist research platform in advance of the closing of the proposed combination, Spring Bank may include certain proceeds from such transaction in its net cash calculation.The Spring Bank directors and officers have signed support agreements committing them to vote in favor of the transaction. These same parties, as well F-star’s key equity holders, directors and officers, have signed lock-up agreements restricting transfers of the combined company’s stock (except as to any shares purchased by such holders in the financing closing immediately prior to the business combination) for 180 days post-closing.The transaction has been approved by the boards of directors of both companies and the equity holders of F-star, who have signed the share exchange agreement. The combined company will be headquartered out of F-star’s existing facilities in Cambridge, U.K. and Cambridge, MA. Following closing, which is expected to occur in late 2020, Spring Bank will be re-named F-star Therapeutics, Inc. and is expected to trade on the Nasdaq Capital Market under the ticker symbol “FSTX”.

Such forward-looking statements are based on our expectations and involve risks and uncertainties; consequently, actual results may differ materially from those expressed or implied in the statements due to a number of factors, including, but not limited to, risks relating to the completion of the combination, including the need for stockholder approval and the satisfaction of closing conditions; the anticipated financing to be completed immediately prior to the closing of the combination; the cash balances of the combined company following the closing of the combination and the F-star financing; the ability of Spring Bank to remain listed on the Nasdaq Capital Market; and expected restructuring-related cash outlays, including the timing and amount of those outlays.
