MEREO BIOPHARMA GROUP PLC
Notes to the Condensed Consolidated Financial Statements
(unaudited)
1. Corporate information
Mereo BioPharma Group plc (the “Company” or “Mereo”) is a clinical-stage, United Kingdom (“UK”) based biopharmaceutical company focused on rare diseases and oncology.
The Company is a public limited company incorporated and domiciled in the UK, and registered in England, with shares publicly traded on the Nasdaq Global Market via American Depositary Shares (“ADSs”) under the ticker symbol MREO. The Company’s registered office is located at Fourth Floor, 1 Cavendish Place, London, W1G 0QF, United Kingdom.
These financial statements are the unaudited condensed consolidated financial statements of Mereo BioPharma Group plc and its subsidiaries for the six months ended June 30, 2022. The principal activities of the Company are the development and commercialization of innovative therapeutic pharmaceutical products.
2. Significant accounting policies
Basis of preparation
The unaudited condensed consolidated financial statements for the six-month period ended June 30, 2022 have been prepared in accordance with International Accounting Standards (IAS) 34,
Interim Financial Reporting
. These consolidated condensed financial statements do not include all information and disclosures required in the annual financial statements in accordance with International Financial Reporting Standards (IFRS) and should be read in conjunction with the Company’s annual consolidated financial statements for the year ended December 31, 2021 filed with the Securities and Exchange Commission (“SEC”) on March 31, 2022.
The financial information is presented in pound sterling (“£”), which is the presentational currency of the Company. The functional currencies of consolidated subsidiaries are pound sterling and US dollars (“$”). All amounts disclosed in the condensed consolidated financial statements and notes have been rounded to the nearest thousand, unless otherwise stated.
The financial information for the year ended December 31, 2021 has been extracted from the Company’s audited financial statements for that year, filed with the SEC on March 31, 2022.
These condensed consolidated financial statements are unaudited and do not constitute statutory accounts of the Company as defined in section 434 of the Companies Act 2006. A copy of the statutory accounts for financial year ended December 31, 2021 has been delivered to the Registrar of Companies. The auditors reported on those accounts and their report was unqualified, did not draw attention to any matters by way of emphasis and did not contain a statement under section 498(2) or (3) of the Companies Act 2006.
Segmental information
The Company has one operating segment. The Chief Operating Decision Maker (“CODM”) is the Chief Executive Officer. The Company has a single portfolio of product candidates, with only direct research and development expenses monitored by product candidate. The CODM makes decisions over resource allocation at an overall portfolio level and the Company’s financing is managed and monitored on a consolidated basis.
Going Concern
The going concern basis has been applied in these condensed consolidated financial statements as the Company has adequate resources to meet its liabilities as they fall due for the foreseeable future and at least 12 months from the issuance date of these condensed consolidated financial statements.
The Company expects to incur significant operating losses for the foreseeable future as it continues its research and development efforts, seeks to obtain regulatory approval of its product candidates and pursues any future product candidates the Company may develop.

Until such time as the Company can generate significant revenue from product sales, or other commercial revenues, if ever, or through licensing and/or collaboration agreements for its rare disease or oncology product candidates, the Company will seek to finance its operations through a combination of public or private equity or debt financings or other sources.
Summary of significant accounting policies
The accounting policies adopted in the preparation of the condensed consolidated financial statements are consistent with those followed in the preparation of the Company’s consolidated financial statements for the year ended December 31, 2021.
Significant accounting estimates and judgments
The preparation of these condensed consolidated financial statements requires the management of the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. The Company bases its estimates and judgments on historical experience and on various other assumptions that it considers to be reasonable. Actual results may differ from these estimates under different assumptions or conditions.
The significant accounting estimates and judgments adopted in the preparation of the condensed consolidated financial statements are consistent with those followed in the preparation of the Company’s consolidated financial statements for the year ended December 31, 2021.
3. Revenue
The Company recognized upfront proceeds of £36.5 million ($50.0 million) from the license and collaboration agreement with Ultragenyx for setrusumab as revenue in the
six-month
period ended June 30, 2021. The variable consideration relating to future milestones and sales royalties will be recognized in the statement of comprehensive income when the milestones are achieved or the underlying commercial sales are made, in the event regulatory approval is obtained.
As a consequence of the license and collaboration agreement with Ultragenyx and in accordance with terms of the 2015 asset purchase with Novartis, the Company made a payment to Novartis of £7.2 million ($10.0 million). The payment included a deduction for costs of £2.4 million which was deferred to be recognized in the statement of comprehensive income when the associated costs are incurred. In the
six-month
period ended June 30, 2022, £0.4 million (six months ended June 30, 2021: £0.9 million) of these deductions were recognized within “Cost of revenue” in the
condensed consolidated 
statement of comprehensive
(loss)/
income. As of June 30, 2022, the remaining balance to be recognized of £
0.9
million (June 30, 2021: £
1.5
 million and December 31, 2021: £
1.3
million) is included within “Other liabilities” in the condensed consolidated balance
sheets
.

under the Navi License Agreement with OncXerna. An associated payment was made to
the former shareholders of Mereo BioPharma 5, Inc. under the Contingent Value Rights Agreement (“
CVR
”)
of a total of $0.9
 
million (£0.7 million),
after deductions of costs, charges and expenditures, which resulted in other income, net of £0.8 million.
6. Earnings per share
Basic (loss)/profit per share is calculated by dividing the (loss)/profit attributable for the period to ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the period. Diluted loss per share is based on dividing the loss attributable for the period, adjusted for the effect of dilutive ordinary shares, by ordinary share equivalents, which includes the weighted average number of ordinary shares outstanding and the effect of dilutive ordinary share equivalents.

For the period ended June 30, 2021, the effect of dilutive ordinary shares is related to Company’s outstanding warrants. For the period ended June 30, 2022, share options, convertible loan notes and warrants were considered to be anti-dilutive as they would have decreased the loss per share and were therefore excluded from the calculation of diluted loss per share. Therefore, the weighted average shares outstanding used to calculate both the basic and diluted loss per share was the same.

The present value of the provision for deferred cash consideration relating to the agreement with AstraZeneca was reviewed at June 30, 2022 (see Note
10
). The change in the period due to changes in timelines or probability of contractual milestones being achieved was a decrease of £0.4 
million which was
recognized as a reduction of the intangible asset in line with our accounting policies.
During the period the Company did not revise the value of any other intangible assets (2021: £nil). As the intangible assets remain under development, no amortization charge has been recognized (2021: £nil).

Share-based payments
The Company has a share option scheme under which options to subscribe for the Company’s shares have been granted to certain
executives, non-executive
directors (“NEDs”) and employees. The share-based payment reserve is used to recognize (i) the value of equity settled share-based payments provided to employees, including key management personnel, as part of their remuneration and (ii) deferred equity consideration.
The total charge for the six months to June 30, 2022 in respect of all share option schemes was £2.4 million (June 30, 2021: £1.8 million).
During the six months ended June 30, 2022, the Company granted 3,996,400 market value options over ADS under the Mereo 2019 Equity Incentive Plan to certain executives and other employees. The weighted average fair value of options granted was $1.23
 per option
.
The weighted average exercise price is $1.39
 per ADS
.
During the same period, the Company granted 507,987 market value options over ADS under the Mereo 2019 NED Equity Incentive Plan to
certain non-executive
directors. The weighted average fair value of options granted was $1.10
 per option
.
 The weighted average exercise price is $1.24
 per ADS
.
Options over ADSs issued during the six months ended June 30, 2022 were valued using the Black-Scholes model with the following weighted average inputs: expected volatility of 96%; risk free interest rate of 1.79%; expected life of 10 years; and market price per ADS of $1.38.
A total of 353,183
deferred restricted stock units, with a weighted average fair value of $1.12
 per restricted stock unit
,
were also granted
 in February 2022
under the Mereo 2019 NED Equity Incentive Plan to certain non-executive directors who elected to receive restricted stock units in lieu of their cash fees for the year commencing February 1, 2022.

The deferred cash consideration is the estimate of the quantifiable but not certain future cash payment obligations due to AstraZeneca for the acquisition of certain assets. This provision is calculated as the risk adjusted net present value of future cash payments to be made by the Company. The payments are dependent on reaching certain milestones based on the commencement and outcome of clinical trials. The likelihood of achieving such milestones is reviewed at the balance sheet date and increased or decreased as appropriate (see Note 8).

Warrants - private placement
As a part of the private placement transaction on June 3, 2020, the participating investors received conditional warrants entitling them to subscribe for an aggregate of 161,048,366 ordinary shares in the Company. The warrants were conditional on certain resolutions being passed at the Company’s general meeting on June 30, 2020. On the passing of the resolutions, the warrants entitled the investors to subscribe for ordinary shares at an exercise price of £0.348 per warrant and are exercisable until June 2023. The warrants are classified as liabilities as the Company does not have an unconditional right to avoid redeeming the instruments for cash. The fair value of the warrant liability was £6.9 million as of June 30, 2022 (£8.0 million as of December 31, 2021). The change in the fair value of £1.1 million was recognized as a gain in the
condensed 
consolidated statement of comprehensive
(loss)/
income. In the six months ended June 30, 2022, 
no
 warrants were exercised.
Warrants – bank loan
As of June 30, 2022 and December 31, 2021, the former lenders of the Company have warrants outstanding to purchase a total of 1,243,908 ordinary shares at an exercise price of £2.95 per share
exercisable until August 2027 
and a total of 1,243,908 ordinary shares at an exercise price of $0.4144 per share
 
exercisable until October 2028
At June 30, 2022, the fair value of these warrants were £0.2 million (December 31, 2021: £0.3 million). The change in the fair value of £0.1 million was recognized as a gain in the
condensed 
consolidated statement of comprehensive
(loss)/
income. There were no warrants exercised during the six months ended June 30, 2022.
Total outstanding warrants
At June 30, 2022, a total of 147,431,351 warrants are outstanding. The warrants outstanding are equivalent to 25% of the ordinary share capital of the Company.

The warrant liability is estimated using a Black Scholes model, taking into account appropriate amendments to inputs in respect of volatility, remaining expected life of the warrants and rates of interest at each reporting date.
The fair value of the provision for deferred cash consideration is estimated by discounting future cash flows using rates currently available for debt on similar terms and credit risk. In addition to being sensitive to a reasonably possible change in the forecast cash flows or the discount rate, the fair value of the deferred cash consideration is also sensitive to a reasonably possible change in the probability of reaching certain milestones. The valuation requires management to use unobservable inputs in the model, of which the significant unobservable inputs are disclosed in the tables below. Management regularly assesses a range of reasonably possible alternatives for those significant unobservable inputs and determines their impact on the total fair value.

   Volatility was estimated by reference to the one year historical volatility of the historical share price of the Company. If the volatility is increased to 149% (six month volatility), the carrying value of the warrants as of June 30, 2022 would increase
to
£10.2

In 2021, volatility was estimated by reference to the

Employee benefit trust
In 2016 the Company set up an Employee Benefit Trust (“EBT”). The EBT holds ADS’s to satisfy the exercise of options by employees under the Company’s share-based incentive schemes.
No funding was loaned to the EBT by the Company during the period to June 30, 2022 (June 30, 2021: nil). The EBT repaid £45,493 of the funding previously loaned by the Company during the period ended June 30, 2021.
The EBT did not purchase any ordinary shares during the period to June 30, 2022 (2021: nil). A total of 78,225 ordinary shares owned by the EBT were used to satisfy exercise of options by employees under the Company’s share-based incentive schemes during the period
 ended June 30, 2022 (June 30, 2021: 145,830).
As of June 30, 2022 a cash balance of £17,741 was held by the EBT. As of December 31, 2021 a cash balance of £17,866 was held by the EBT.
