Summit Therapeutics plc reports its financial results and provides an update on its operational progress for the third quarter and nine months ended 31 October 2019. Oxford, UK, and Cambridge, MA, US, 17 December 2019 - Summit Therapeutics plc (NASDAQ: SMMT, AIM: SUMM) today reports its financial results and provides an update on its operational progress for the third quarter and nine months ended 31 October 2019. “Our enthusiasm for ridinilazole continues to grow. Phase 2 clinical data presented this past quarter showed ridinilazole had significant improvements in patient quality of life measures and preservation of the gut microbiome compared to the current standard of care. These findings reinforce our belief that ridinilazole could provide better overall clinical, physical and mental outcomes for patients with C. difficile infection,” said Glyn Edwards, Chief Executive Officer of Summit. “We were also pleased to announce recently the proposed $50 million investment into Summit that will primarily be used to support the ongoing Phase 3 clinical programme and commercial preparatory activities for ridinilazole. We look forward to continuing to advance ridinilazole through our landmark Phase 3 clinical trials that remain on track to report results in the second half of 2021.” Ridinilazole for C. difficile Infection (‘CDI’) Ri-CoDIFy Phase 3 landmark clinical trials aim to support registration of the precision antibiotic ridinilazole in the US and other territories, and its adoption as a first-line treatment for CDI by: showing superiority over the current standard of care, vancomycin, using a composite endpoint measuring sustained clinical response; generating health economic data to help support ridinilazole’s commercial launch, if approved; and undertaking deep microbiome analyses to evaluate ridinilazole’s preservation of the gut microbiome. The Phase 3 clinical programme remains on track for expected reporting of top-line data in the second half of 2021. The trials had enrolled a total of 128 patients as at the end of November 2019 with over two thirds of the 300 planned clinical trials sites having been opened. Reported new Phase 2 clinical trial data that showed ridinilazole improved patients’ quality of life compared to vancomycin, including statistically significant improvements in measurements of physical and mental health. Additional data from the Phase 2 clinical trial provided mechanistic insights into how ridinilazole preserved the diversity of the gut microbiome in patients with CDI to maintain the balance of the metabolome of active chemicals made or modified by gut bacteria that help prevent C. difficile recurrence. These new results were reported at the ID Week Conference held in Washington DC in October 2019. Commercial and medical affairs hires have been made in the United States to support work to prepare for a potential launch and to secure future market access for ridinilazole, if approved. Discuva Platform Enterobacteriaceae DDS-04 compound series is a new class of antibiotics in lead optimisation that acts via the novel bacterial target LolCDE with the potential to treat infections caused by the Gram-negative bacteria, Enterobacteriaceae. In vivo proof of concept has been demonstrated with a DDS-04 series compound in pneumonia, sepsis and urinary tract infection (‘UTI’). Data from all three disease models were presented at the ASM / ESCMID Conference held in September. Gonorrhoea The focus of the gonorrhoea programme has shifted from SMT-571 to related compounds as part of ongoing preclinical studies as the Company seeks to bring an optimal clinical candidate forward. The lead optimisation work is being supported by an award of up to $4.5 million from CARB-X. Corporate Highlights A proposed fundraising of approximately $50 million through a subscription and placing of new ordinary shares and warrants to existing investors (the ‘Fundraising’) was announced on 6 December 2019. The Fundraising requires approval by shareholders at a general meeting of the Company to be held on 23 December 2019. If the Fundraising is completed, the net proceeds, together with the Company’s existing cash resources and funding agreements, are expected to extend its cash runway to 31 January 2021. Conditional on the Fundraising being completed, the board of directors will be restructured to support preparations for the potential commercial launch of ridinilazole for the treatment of CDI. Specifically, conditional on the Fundraising being completed, Mr Robert W. Duggan, Mr Manmeet Soni, Dr Elaine Stracker and Dr Ventzislav Stefanov were appointed as non-executive directors, and Dr Frank Armstrong, Mr Leopoldo Zambeletti and Mr David Wurzer are stepping down from the board of directors. Mr Glyn Edwards will take the role of Chairman in addition to his existing role as Chief Executive Officer. As a condition of the Fundraising, it is proposed that the admission of the Company’s ordinary shares to trading on AIM will be cancelled (‘AIM Delisting’) with effect from 7.00 am on 24 February 2020. The Company’s American Depositary Shares (‘ADSs’) will remain listed on the Nasdaq Stock Market where one ADS is represented by five ordinary shares. The proposed AIM Delisting reflects the increasing focus of Summit’s business operations on the United States, and specifically the Company’s plans to commercialise ridinilazole in the United States with its own specialised sales force, if approved. Financial Highlights Cash and cash equivalents at 31 October 2019 of £13.6 million compared to £26.9 million at 31 January 2019. Cash position does not include the proposed Fundraising of approximately $50 million announced on 6 December 2019 (see Corporate Highlights above for further details). Loss for the three months ended 31 October 2019 of £7.0 million compared to a loss of £8.1 million for the three months ended 31 October 2018. The Company today announces that it has changed its accounting reference date from 31 January to 31 December with immediate effect. This announcement contains inside information for the purposes of Article 7 of EU Regulation 596/2014 (MAR). About Summit Therapeutics Summit Therapeutics is a leader in antibiotic innovation.

FINANCIAL REVIEW Other Operating Income Other operating income was £3.8 million for the three months ended 31 October 2019, as compared to £2.8 million for the three months ended 31 October 2018. Other operating income was £12.8 million for the nine months ended 31 October 2019, as compared to £9.0 million for the nine months ended 31 October 2018. These increases resulted primarily from the recognition of operating income from Summit’s funding contract with BARDA for the development of ridinilazole, which was £3.6 million for the three months ended 31 October 2019 as compared to £2.2 million for the three months ended 31 October 2018 and £11.7 million for the nine months ended 31 October 2019 as compared to £7.5 million for the nine months ended 31 October 2018. As of 31 October 2019, an aggregate of £26.6 million ($34.3 million) of the total committed BARDA funding of $53.6 million has been recognised. The Group also recognised operating income related to the CARB-X award supporting the development of the Company’s gonorrhoea programme of £0.2 million during the three months ended 31 October 2019 as compared to £0.1 million for the three months ended 31 October 2018 and £0.6 million during the nine months ended 31 October 2019 as compared to £0.3 million for the nine months ended 31 October 2018. Revenue Revenue was £0.1 million for the three months ended 31 October 2019 compared to £0.7 million for the three months ended 31 October 2018. Revenue was £0.5 million for the nine months ended 31 October 2019 compared to £42.5 million for the nine months ended 31 October 2018. Revenue of £0.1 million recognised during the three months ended 31 October 2019 and £0.4 million recognised during the nine months ended 31 October 2019 related to the receipt of a $2.5 million (£1.9 million) upfront payment in respect of the licence and commercialisation agreement signed with Eurofarma Laboratórios SA in December 2017 for the exclusive right to commercialise ridinilazole in specified Latin American and Caribbean countries. The decreases in revenue recognised are principally due to the reduction in revenue related to the Sarepta licence and collaboration agreement for the treatment of Duchenne muscular dystrophy (‘DMD’). Revenue relating to the cost-share arrangement under the Sarepta agreement recognised during the three months ended 31 October 2019 amounted to £nil and during the nine months ended 31 October 2019 amounted to £0.1 million, as compared to total revenues relating to the upfront payment, development milestone payment and cost-share arrangement recognised during the three months ended 31 October 2018 of £0.6 million and during the nine months ended 31 October 2018 of £41.9 million. The agreement with Sarepta was terminated, effective August 2019, with no material ongoing obligations for either party. Operating Expenses Research and Development Expenses Research and development expenses decreased by £1.0 million to £7.2 million for the three months ended 31 October 2019 from £8.2 million for the three months ended 31 October 2018. Research and development expenses decreased by £4.9 million to £24.7 million for the nine months ended 31 October 2019 from £29.6 million for the nine months ended 31 October 2018. These decreases primarily reflect decreases in clinical programme costs pertaining to the historical DMD programme. Expenses related to the CDI programme increased by £4.2 million to £16.9 million for the nine months ended 31 October 2019 from £12.7 million for the nine months ended 31 October 2018. This increase primarily related to clinical operations and supply manufacturing activities related to the ongoing Ri-CoDIFy Phase 3 clinical trials of ridinilazole that commenced in February 2019. Investment in the Group’s preclinical antibiotic pipeline was £2.0 million for the nine months ended 31 October 2019 compared to £1.1 million for the nine months ended 31 October 2018. This increase primarily related to preclinical development activities for DDS-04 series for the treatment of Enterobacteriaceae infections and the gonorrhoea programme. Expenses related to the DMD programme decreased to £0.2 million for the nine months ended 31 October 2019 from £8.6 million for the nine months ended 31 October 2018. The Group does not expect to incur further significant costs for this programme. Other research and development expenses decreased by £1.7 million to £5.6 million during the nine months ended 31 October 2019 as compared to £7.3 million during the nine months ended 31 October 2018, which was driven by a decrease in staffing and facility costs. General and Administration Expenses General and administration expenses decreased by £0.3 million to £4.4 million for the three months ended 31 October 2019 from £4.7 million for the three months ended 31 October 2018. General and administration expenses decreased by £2.1 million to £7.2 million for the nine months ended 31 October 2019 from £9.3 million for the nine months ended 31 October 2018. These decreases were driven primarily by the non-cash charge for the acceleration of share-based payment expense resulting from the surrender of share options offset by a net positive movement in exchange rate variances accounted for in the comparative periods. Finance Costs Finance costs recognised during the three and nine months ended 31 October 2019 relate to lease liability interest payable and the unwinding of the discount associated with provisions. Finance costs were £0.1 million for the three months ended 31 October 2019 compared to £0.1 million for the three months ended 31 October 2018. Finance costs were £0.2 million for the nine months ended 31 October 2019 compared to £0.4 million for the nine months ended 31 October 2018. This decrease relates to the cessation of the unwinding of the discount following the remeasurement in June 2018 of the financial liabilities on funding arrangements for the historical DMD programme. Taxation The income tax credit for the three months ended 31 October 2019 was £0.7 million as compared to £1.3 million for the three months ended 31 October 2018. The income tax credit for the nine months ended 31 October 2019 was £2.6 million as compared to £1.7 million for the nine months ended 31 October 2018. The Group’s current net tax credit for the periods reflects the accrued UK research and development tax credit based on management’s estimate of the qualifying expenditure relating to research and development activities carried out by the Group, the taxes relating to the US operations and the release of deferred tax liabilities associated with the amortisation of intangible assets. Losses Loss before income tax was £7.8 million for the three months ended 31 October 2019 compared to a loss before income tax of £9.4 million for the three months ended 31 October 2018. Loss before income tax was £18.8 million for the nine months ended 31 October 2019 compared to a profit before income tax of £10.9 million for the nine months ended 31 October 2018. Net loss for the three months ended 31 October 2019 was £7.0 million with a basic loss per share of 4 pence compared to a net loss of £8.1 million for the three months ended 31 October 2018 with a basic loss per share of 10 pence. Net loss for the nine months ended 31 October 2019 was £16.2 million with a basic loss per share of 10 pence compared to a net profit of £12.7 million for the nine months ended 31 October 2018 with a basic earnings per share of 16 pence. The profits recorded during the nine months ended 31 October 2018 were due to the recognition of all remaining deferred revenue related to the Sarepta agreement. Cash Flows The Group had a net cash outflow of £13.7 million for the nine months ended 31 October 2019 as compared to a net cash outflow of £8.2 million for the nine months ended 31 October 2018. Operating Activities For the nine months ended 31 October 2019, net cash used in operating activities was £13.2 million compared to £22.1 million for the nine months ended 31 October 2018. This positive movement of £8.9 million was driven by an increase in cash received from licensing agreements and funding arrangements of £0.8 million, an increase in taxation cash inflows of £5.4 million due to the timing of receipt of the Group’s research and development tax credits receivable on qualifying expenditure in respect of financial years ended 31 January 2017, 2018 and 2019, and a decrease in operating costs of £10.2 million as a result of the Group’s decision to discontinue development of ezutromid. Investing Activities Net cash used in investing activities was £0.2 million for the nine months ended 31 October 2019 as compared to £0.1 million for the nine months ended 31 October 2018. Net cash used in investing activities for the nine months ended 31 October 2019 includes amounts paid to acquire property, plant and equipment and intangible assets, offset by bank interest received on cash deposits. Financing Activities Net cash used in financing activities for the nine months ended 31 October 2019 of £0.3 million primarily relates to lease liability repayments. Net cash generated from financing activities for the nine months ended 31 October 2018 of £14.0 million was primarily driven by £14.1 million of proceeds, net of transaction costs, received following the Group’s equity placing in March 2018. Financial Position and Cash Runway Guidance As at 31 October 2019, total cash and cash equivalents held were £13.6 million (31 January 2019: £26.9 million). On 6 December 2019, the Group announced a proposed Fundraising of approximately $50 million which is subject to certain shareholder approvals being obtained at a general meeting to be held on 23 December 2019. Please see Note 1 for further details should the Group not receive shareholder approval. If shareholder approval is obtained, the net proceeds of the Fundraising, together with the Group’s existing cash resources and funding agreements, are expected to extend its cash runway to 31 January 2021.

‘Basis of Accounting - Adoption of IFRS 16 ‘ Leases ’’ The accompanying notes form an integral part of these condensed consolidated interim financial statements. NOTES TO THE FINANCIAL INFORMATION For the three and nine months ended 31 October 2019 1. Basis of Accounting The unaudited condensed consolidated interim financial statements of Summit Therapeutics plc (‘Summit’ and the ‘Company’) and its subsidiaries (together, the ‘Group’) for the three and nine months ended 31 October 2019 have been prepared in accordance with International Financial Reporting Standards (‘IFRS’) and International Financial Reporting Interpretations Committee (‘IFRIC’) interpretations as issued by the International Accounting Standards Board and with those parts of the Companies Act 2006 applicable to companies reporting under IFRS including those applicable to accounting periods ending 31 January 2020 and the accounting policies set out in Summit’s consolidated financial statements. There have been no changes to the accounting policies as contained in the annual consolidated financial statements as of and for the year ended 31 January 2019 other than as described below. These condensed consolidated interim financial statements do not include all information required for full statutory accounts within the meaning of section 434 of Companies Act 2006 and should be read in conjunction with the consolidated financial statements of the Group as at 31 January 2019 (the ‘2019 Accounts’). The 2019 Accounts, on which the Company’s auditors delivered an unqualified audit report, are available on the Group’s website at and were delivered to the Registrar of Companies following the 2019 Annual General Meeting. The auditor’s report did not contain any statement under section 498 of the Companies Act 2006 but did contain a statement from the auditors drawing the shareholders’ attention to the Group’s need to raise additional capital as noted below. Whilst the financial information included in this announcement has been prepared in accordance with IFRS and IFRIC interpretations as issued by the International Accounting Standards Board and with those parts of the Companies Act 2006 applicable to companies reporting under IFRS, this announcement does not itself contain sufficient information to comply with IFRS. The interim financial statements have been prepared assuming the Group will continue on a going concern basis. Based on management’s forecasts, the Group’s existing cash and cash equivalents, anticipated payments from BARDA under its contract for the development of ridinilazole and anticipated payments from CARB-X under its contract for the development of its gonorrhoea antibiotic programme are expected to be sufficient to enable the Group to fund its operating expenses and capital expenditure requirements through to at least 31 January 2020. On 6 December 2019, the Group announced a proposed Fundraising of approximately $50 million through a subscription and placing of new ordinary shares and warrants to existing investors (‘Fundraising’), which is subject to certain shareholder approvals being obtained at a general meeting to be held on 23 December 2019, and certain customary closing conditions being satisfied. If shareholder approval is obtained, the net proceeds of the Fundraising, together with the Group’s existing cash resources and funding agreements, are expected to extend its cash runway to 31 January 2021. The Group expects to use these funds to support the continued Phase 3 clinical programme of ridinilazole for the treatment of CDI; preparatory activities to support commercial launch of ridinilazole, if approved; development of early-stage research projects; and general corporate purposes. Should the Company not receive shareholder approval, the Fundraising would not proceed and the Group would need to take immediate steps to preserve cash including, amongst others, stopping the ongoing Phase 3 clinical trials of ridinilazole and ceasing its Discuva Platform activities and associated research programmes. The failure of the Group to obtain the necessary shareholder approval to enable the proposed Fundraising to proceed would therefore have a material adverse effect on the Group’s business, results of operations and financial condition. These circumstances represent a material uncertainty which may cast and raise significant doubt on the Group’s ability to continue as a going concern. The interim financial statements do not contain any adjustments that might result if the Group was unable to continue as a going concern. The financial information for the three and nine month periods ended 31 October 2019 and 2018 are unaudited. Solely for the convenience of the reader, unless otherwise indicated, all pound sterling amounts stated in the Consolidated Statement of Financial Position as at 31 October 2019, the Consolidated Statement of Comprehensive Income for the three and nine months ended 31 October 2019 and Consolidated Statement of Cash Flows for the nine months ended 31 October 2019 have been translated into US dollars at the rate on 31 October 2019 of $1.2939 to £1.00. These translations should not be considered representations that any such amounts have been, could have been or could be converted into US dollars at that or any other exchange rate as at that or any other date. The Board of Directors of the Company approved this statement on 17 December 2019. Adoption of IFRS 16 ‘ Leases’ IFRS 16 specifies how to recognise, measure, present and disclose leases. The standard provides a single lessee accounting model, requiring lessees to recognise assets and liabilities for all leases unless the lease term is 12 months or less or the underlying asset has a low value. The standard is effective for reporting periods beginning on or after 1 January 2019 and replaces the accounting standard IAS 17 ‘ Leases’ . Two adoption methods are permitted for transition: retrospectively to all prior reporting periods presented in accordance with IAS 8 ‘ Accounting Policies, Changes in Accounting Estimates and Errors’ , with certain practical expedients permitted; or retrospectively with the cumulative effect of initially applying the standard recognised at the date of initial application. Accounting policy At inception of a contract, the Group assesses whether a contract is, or contains, a lease based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Group recognises a right-of-use asset within property, plant and equipment and a lease liability at the lease commencement date. The right-of-use asset is initially measured based on the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received. The assets are depreciated to the earlier of the end of the useful life of the right-of-use asset or the lease term using the straight-line method. The lease term includes periods covered by an option to extend if the Group is reasonably certain to exercise that option and periods covered by an option to terminate if it is reasonably certain not to exercise that option. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group’s incremental borrowing rate. The lease liability is subsequently measured at amortised cost using the effective interest method and is remeasured when there is a change in future contractual lease payments or if the Group changes its assessment of whether it will exercise a purchase, extension or termination option. The Group adopted this new standard effective 1 February 2019, as required, using the full retrospective transition method in accordance with IAS 8 ‘ Accounting Policies, Changes in Accounting Estimates and Errors’ . Under this method, the Group will adjust its results for the years ended 31 January 2018 and 2019 and applicable interim periods, as if IFRS 16 had been effective for those periods. The Group has assessed the effect of adoption of this standard as it relates to its UK leased properties in Oxford and Cambridge and has concluded that any other contracts are not within the scope of IFRS 16 or are of low value, for which the Group has elected not to apply the requirement of IFRS 16. Due to the adoption of IFRS 16, the Group has recognised both right-of-use assets and lease liabilities related to its UK leased properties. The Group no longer recognises a lease incentive accrual and has reclassified some costs from research and development expenses and general and administration expenses to finance costs, being the interest expense on lease liabilities. In addition, some amounts previously presented as cash outflows from operating activities in the Group’s Consolidated Statement of Cash Flows are now presented as cash flows from investing or financing activities. This change in accounting policy has been reflected retrospectively in the comparative Statement of Financial Position for the year ended 31 January 2019, the comparative Statement of Comprehensive Income, Statement of Cash Flows and Statement of Changes in Equity for the nine months ended 31 October 2018, including the opening accumulated losses reserve at 1 February 2018 and 1 February 2019. The impact of the change in accounting policy to IFRS 16 discussed above on the comparatives to the unaudited condensed consolidated interim financial statements is disclosed in the following tables.

(Loss) / earnings per Share Calculation The calculation of (loss) / earnings per share is based on the following data: Three months ended 31 October 2019 Three months ended 31 October 2018 Nine months ended 31 October 2019 Nine months ended 31 October 2018 (Adjusted*) (Adjusted*) 000s 000s 000s 000s (Loss) / profit for the period (7,030 ) (8,134 ) (16,214 ) 12,657 Weighted average number of ordinary shares for basic (loss) / earnings per share 160,495 82,137 160,463 80,279 Effect of dilutive potential ordinary shares (share options and warrants) — — — 527 Weighted average number of ordinary shares for diluted (loss) / earnings per share 160,495 82,137 160,463 80,806 Basic (loss) / earnings per ordinary share from operations £ (0.04 ) (0.10 ) (0.10 ) 0.16 Diluted (loss) / earnings per ordinary share from operations £ (0.04 ) (0.10 ) (0.10 ) 0.16 * See Note 1 - ‘Basis of Accounting - Adoption of IFRS 16 ‘ Leases ’’ Basic (loss) / earnings per ordinary share has been calculated by dividing the (loss) / profit for the three and nine months ended 31 October 2019 by the weighted average number of shares in issue during the three and nine months ended 31 October 2019. Diluted earnings per ordinary share has been calculated by adjusting the weighted average number of ordinary shares outstanding to assume conversion of all potentially dilutive ordinary shares. Potentially dilutive ordinary shares represent the number of shares that could have been acquired at fair value based on the monetary value of the subscription rights attached to share options in-the-money compared with the number of shares that would have been issued assuming the exercise of share options in-the-money. IAS 33 ‘Earnings per Share’ requires the presentation of diluted earnings per share where a company could be called upon to issue shares that would decrease net profit or loss per share. As the Group reported net losses for the three and nine months ended 31 October 2019, the weighted average number of ordinary shares outstanding used to calculate the diluted (loss) / earnings per ordinary share is the same as that used to calculate the basic (loss) / earnings per ordinary share, as the exercise of share options would have the effect of reducing loss per ordinary share which is not dilutive. 3. Issue of Share Capital On 23 April 2019, 104,877 ordinary shares were issued following the exercise of restricted stock units (‘RSUs’). This exercise of RSUs raised net proceeds of £1,049. The new ordinary shares issued in connection with the RSUs exercised rank pari passu with existing ordinary shares. As of 31 October 2019, the number of ordinary shares in issue was 160,494,758. 4 . Post Balance Sheet Events On 6 December 2019, the Group announced a proposed Fundraising of approximately $50 million through a subscription of 166,157,050 new ordinary shares and a placing of 9,221,400 new ordinary shares at a subscription and placing price of 22.1 pence per new ordinary share (‘Fundraising’). The Fundraising requires approval by shareholders at a general meeting of the Company to be held on 23 December 2019. As a condition of the proposed Fundraising, it is proposed that the admission of the Company’s ordinary shares to trading on AIM will be cancelled (‘AIM Delisting’). The Company’s American Depositary Shares (‘ADSs’) will remain listed on the Nasdaq Stock Market where one ADS is represented by five ordinary shares. The proposed AIM Delisting reflects the increasing focus of Summit’s business operations on the United States, and specifically the Company’s plans to commercialise ridinilazole in the United States with its own specialised sales force, if approved. Should shareholders approve the AIM Delisting, the final day of trading on AIM of the ordinary shares is expected to be 21 February 2020. On that basis, the AIM Delisting would take effect at 7:00 am on 24 February 2020. Thereafter, ordinary shares will continue to be capable of being held and transferred in certificated form, but there will be no public market in the UK on which shareholders will be able to trade ordinary shares with all public trading of securities in the Company taking place on Nasdaq by way of ADSs. -END-
