7 LETTER FROM THE BOARD

Xiamen Sunstone shall, within 15 working days from the completion date of the Subscription, complete the changing procedures regarding the Subscription (including the change of the industrial and commercial registration for the change of shareholders and the members of the board for the new term) or the filing procedures.

Assuming that save for the Subscription there will be no change in the issued share capital of Xiamen Sunstone between the date of the Subscription Agreement and the completion of the industrial and commercial changing registration following the Subscription Completion, the equity interest of Xiamen Sunstone will be owned by XRBG as to 75.74%, XPDC as to 12.07%, Xiamen Port Development as to 8.10%, the Individual Shareholders as to 3.66% and XRBM as to 0.43%, as XRBM will also subscribe for 466,000 new shares to be issued by Xiamen Sunstone as a pre-IPO internal restructuring transaction no later than the Subscription Completion.

Lock-up The Subscription Shares, once issued, will not be subject to any lock-up restriction at any time after the Subscription Completion.

Valuation of Xiamen Sunstone and the Target Company As the valuation of Xiamen Sunstone and the Target Company was prepared by the PRC Qualified Valuer based on an income approach, the valuation as set out in the relevant valuation reports is regarded as a profit forecast under Rule 14.61 of the Listing Rules and was based on certain key assumptions including, without limitation: (i) the assets to be valued are being transacted and the professional valuer simulates the market for appraisal according to the transaction conditions of the assets to be valued; (ii) the assets can be traded freely in a perfectly competitive market, the value of which depends on the value judgement of independent buyers and sellers under certain market demand and supply conditions; (iii) the operating entity to be valued will be operated as a going concern and will not cease or terminate to operate in the foreseeable and predictable future; (iv) there would be no material change to the prevailing political, legal, market or economic conditions in the PRC or other countries or areas which has a material impact on the business of the unit and its subsidiaries to be assessed;

8 LETTER FROM THE BOARD

(v) there would be no force majeure events or unpredictable factors to severely interrupt the operation and business of the unit and its subsidiaries to be assessed; (vi) the operation and management team of the unit and its subsidiaries to be assessed are diligent and there would be no material change to the existing scope of business, and its internal control system is effective and complete with sufficient and appropriate risk management measures; (vii) the primary information and financial information are true, accurate and complete, and the title of the assets under assessment are clear, legal and complete and are vested to the unit and its subsidiaries to be assessed; and (viii) the unit and its subsidiaries to be assessed are in full compliance of prevailing national and local laws and regulations and all licences, permits, consents and other legal or administrative authorisations issued by the relevant local and national governmental authorities and organisations necessary for its use of assets and operation are valid and effective in use as at the benchmark assessment date.

According to the valuation reports of Xiamen Sunstone and the Target Company, the respective appraised value of each of their entire equity interest as at the Benchmark Assessment Date by adopting the income approach and the asset-based approach are as follows (all in RMB): Xiamen Target Sunstone Company By income approach ...... 1,462,700,000 136,400,000 By asset-based approach ...... 1,201,861,400 132,232,000

As set out in the valuation report of Xiamen Sunstone, there is a difference of RMB260,838,600 between the valuation results of the entire equity interest of Xiamen Sunstone by adopting the income approach and the asset-based approach respectively, representing approximately 17.8% of the appraised value of the entire equity interest of Xiamen Sunstone. The Board understands from the PRC Qualified Valuer that the main reason for such discrepancy is that the assessment mentality of the asset-based approach is to reflect the replacement cost of the existing assets of an enterprise by first aggregating the appraised values of its asset and then deducting the appraised values of its liabilities, while the consideration of the income approach is to reflect the present quantitative value of the future comprehensive profitability of the entire assets of an enterprise after taken into account of intangible factors that may significantly affect its future income, such as production techniques, asset condition, operation and management capability, sale and distribution network and goodwill.

In addition, to the best of the Directors’ knowledge, information and belief, having made all reasonable enquiries, as at the Latest Practicable Date, (i) the houses and buildings with incomplete or defective valuation information (such as ownership) as identified in the valuation reports of Xiamen Sunstone and the Target Company (the “Defective Properties”) are occupied by the respective entity as leased properties merely used as ancillary infrastructure or fixtures which have no material impact on the production and business operation of Xiamen Sunstone or Target Company; (ii) there has not been any dispute with or any title claim by any third party against the landlords as to the Defective Properties which might affect the continuous occupation of the Defective Properties by Xiamen Sunstone or the Target Company.

Xiamen Sunstone is the leading corporation in the concrete industry in Xiamen and Fujian Province and hence enjoys a competitive edge in the production of commodity concrete and

9 LETTER FROM THE BOARD manufacturing of cement and cement products in the local and provincial markets. The Board understands from the PRC Qualified Valuer that as (i) the operation, management and business performance of Xiamen Sunstone have steadily carried out year-by-year; (ii) the net profits of Xiamen Sunstone have demonstrated a significant upward trend over the last three years with the historical gross profit margin of approximately 16.6% for 2019 and with a projected average gross profit margin at approximately 16.7% for the commodity cement business from 2020 to 2024; and (iii) the main source of revenue and expected annual income of Xiamen Sunstone are recurring and are relatively stable, predictable and quantifiable with an expected growth rate of the operating revenue at approximately 0.7% to 2.7% per annum from 2020 to 2024 with a compound annual growth rate of about 1.7% and with no growth for the subsequent years until perpetual for the sake of prudent, the PRC Qualified Valuer considered that the adoption of the income approach (with a discount rate projected for future cash inflow at 12.18% after taken into account of certain relevant factors which are in line with PRC market practice as further elaborated in the letter from the Independent Financial Adviser set out on pages 20 to 36 of this circular) over the asset-based approach could better reflect the intrinsic value of Xiamen Sunstone in an objective manner and therefore the Board considers that (i) the above assumptions, considerations and projections by the PRC Qualified Valuer are fair and reasonable and are in line with the prevailing PRC market practice; and (ii) it is appropriate to adopt the income approach for the valuation of Xiamen Sunstone.

Waiver from the Stock Exchange Given that the Target Company is a non wholly-owned subsidiary of the Company as at the date of the Equity Transfer Agreement and hence the valuation of which for the Disposal constitutes a profit forecast under Rule 14.61 of the Listing Rules and shall be subject to the requirements under Rule 14.62 of the Listing Rules, the Company has applied for, and the Stock Exchange has granted a waiver from strict compliance of the requirements under Rules 14.60A, 14.62(2), 14.62(3) and Paragraph 29(2) of Appendix 1B of the Listing Rules regarding the valuation of the Target Company based on the following grounds: (i) under PRC regulations, the Equity Transfer constitutes a disposal or transfer of state- owned assets in Xiamen which requires a valuation conducted by a qualified PRC valuer as approved by Xiamen SASAC and hence the valuation report of the Target Company has to be issued as a mandatory requirement for the Equity Transfer and was therefore prepared solely by the PRC Qualified Valuer to fulfil this strict legal requirement to discharge the Group’s passive responsibility and was not made of its own initiative; (ii) the Group is not, and was not, involved in the preparation of the valuation report of the Target Company, save for providing certain historical financial information in respect of the Target Company to the PRC Qualified Valuer for their preparation of the said valuation report, which was a completely independent work done by the PRC Qualified Valuer with any additional input, instruction or guidance of any nature from any member of the Group; (iii) upon completion of the Equity Transfer and the Subscription, the Target Company will cease to be a subsidiary of the Group and therefore their results would not be consolidated with the Group. In addition, the Company’s 8.1% indirect equity interest in the Target Company via Xiamen Sunstone upon completion of the Equity Transfer and the Subscription as a whole would be insignificant to the economic and financial scale of the Group;

10 LETTER FROM THE BOARD

(iv) the PRC Qualified Valuer was introduced and recommended by Xiamen Sunstone for the preparation of the valuation of the Target Company for consistency purposes and was jointed appointed by Xiamen Sunstone and the Company with a fee split on an arm’s length basis based on the equity interest held by each parent company in the Target Company; and (v) in determining the Equity Transfer Consideration, the Board has considered other factors besides the valuation of the Target Company, including without limitation the net asset value of the Target Company.

For the avoidance of doubt, the abovementioned waiver does not applicable to the valuation of Xiamen Sunstone as it is not a subsidiary of the Company as at the date of the Subscription Agreement and will not become a subsidiary of the Group after the Subscription Completion.

Information of Xiamen Sunstone Xiamen Sunstone was established in the PRC in September 2003 and is principally engaged in, inter alia, (i) production of commodity concrete; and (ii) manufacturing of cement, cement products and building materials. As at the date of this circular, its equity interest is owned by XRBG as to 82.8%, XPDC as to 13.2% and the Individual Shareholders as to 4.0%.

According to the audited consolidated financial statements of Xiamen Sunstone which were prepared pursuant to the Chinese Enterprise Accounting Standards, (i) the consolidated net asset value of Xiamen Sunstone as at 31 December 2019 amounted to approximately RMB872,614,151; and (ii) the profits (both before and after taxation) of Xiamen Sunstone for the two years ended 31 December 2018 and 2019 are as follows:

For the year ended For the year ended 31 December 2018 31 December 2019 (in RMB) (in RMB) Profits before taxation ...... 117,371,651 208,090,474 Profits after taxation ...... 92,345,503 167,099,345

The original cost of the equity interests currently held by XRBG, XPDC and the Individual Shareholders amount to their respective aggregate capital contributions made into Xiamen Sunstone since the establishment of Xiamen Sunstone, which were approximately RMB82,800,000, RMB13,200,000 and RMB4,000,000. The Board is of the view that such original acquisition costs incurred by XRBG, XPDC and the Individual Shareholders have no relevancy to the determination of the Subscription Consideration.

Changes in Shareholding Structure of Xiamen Sunstone Assuming that save for the Subscription there will be no change in the issued share capital of Xiamen Sunstone between the date of the Subscription Agreement and the completion of the industrial and commercial changing registration following the Subscription Completion, the changes in the shareholding structures of Xiamen Sunstone as a result of the Subscription will be as follows:

As at the date of this Immediately after announcement Subscription Completion Number of shares % Number of shares % XRBG ...... 82,800,000 82.80 82,280,000 75.74 XPDC ...... 13,200,000 13.20 13,200,000 12.07 Xiamen Port Development ...... — — 8,854,000 8.10 Individual Shareholders ...... 4,000,000 4.00 4,000,000 3.66 XRBM ...... — — 466,000 0.43 Total: ...... 100,000,000 100.00 109,320,000 100.00

Financial Effect of the Equity Transfer and the Subscription Upon the Equity Transfer Completion and the Subscription Completion, (i) the entire equity interest of the Target Company will be owned by Xiamen Sunstone as XRBM will also transfer its 5% equity interest in the Target Company to Xiamen Sunstone as a pre-IPO internal restructuring transaction no later than the Equity Transfer Completion and therefore the Target Company will cease to be a subsidiary of the Group; and (ii) Xiamen Sunstone will remain as a non wholly-owned subsidiary of XRBG and its equity interest upon the Subscription Completion will be owned by XRBG as to 75.74%, XPDC as to 12.07%, Xiamen Port Development as to 8.10%, the Individual Shareholders as to 3.66% and XRBM as to 0.43%, as XRBM will also subscribe for 466,000 new shares to be issued by Xiamen Sunstone as another pre-IPO internal restructuring transaction no later than the Subscription Completion.

It is currently intended that RMB129,507,458 out of the proceeds from the Equity Transfer at RMB129,580,000 will be entirely applied to fund the Subscription Consideration.

A. Optimisation of investment structure and financial performance Given that (i) the Group expects to recognise a gain of approximately RMB32,880,000 from the Equity Transfer before deduction of relevant expenses arising therefrom to be incurred by Xiamen Port Development; and (ii) the Target Company’s profitability is lower than Xiamen Sunstone as the average net asset rates of return of the Target Company and Xiamen Sunstone for the three years between 2017 and 2019 amounts to approximately 5.5% and approximately 13.8% respectively, and therefore the profitability of the Target Company is lower than Xiamen Sunstone, the Board is of the view that, through the abovementioned integration, the Group expects to enhance its investment return and is able to secure a foreseeable and more stable source of income in reliance on the superior bargaining power of Xiamen Sunstone in Xiamen based on its sound, valuable and local hands-on commercial experience and significant economies of scale, as well as beneficial to the Group to further pool its resources for developing port-related business.

B. Enhancement of business competitiveness of the concrete and cement-related products The Group and XRBG intend to utilise Xiamen Sunstone as a unified platform to solidify its market position as the leading corporation in the concrete industry in Xiamen and Fujian Province and hence further improve its overall operating efficiency and competitiveness in the local and periphery commodity concrete and cement-related product market through optimisation of business structure and supply of quality and cost-effective products via reasonable resource integration and deployment in order to expand the concrete-related business in joint effort.

C. Obtaining future listing dividend of Xiamen Sunstone and promoting asset securitisation Xiamen Sunstone is planning its initial public offering and has been entered the pre-listing tutoring period since July 2018. In the event of the successful listing of Xiamen Sunstone, the Group could, by way of the Equity Transfer and Subscription, dispose of the Target Company (which has a lower profitability than Xiamen Sunstone) in exchange for its role as a pre-IPO strategic investor of Xiamen Sunstone so as to obtain the equity interest premium income that may be generated after the successful listing of Xiamen Sunstone in the future for promoting the asset securitisation of the members of the Group. To the best of the Board’s knowledge, information and belief, having made all reasonable enquiries, Xiamen Sunstone intends to strive for the lodging of a formal listing application at the China Securities Regulatory Commission by end of 2021.

The Directors (including all the independent non-executive Directors) have approved the entering into of the Subscription Agreement and the Subscription contemplated thereunder. Despite the

14 LETTER FROM THE BOARD

Equity Transfer and the Subscription as a whole shall be regarded as an one-off corporate restructuring exercise which would not fall within the ordinary and usual course of business of the Group, the Directors have considered the terms of the Subscription Agreement and are of the view that the same are on normal commercial terms, are fair and reasonable and are in the interests of the Group and the Shareholders as a whole.

Listing Rules implications Since (i) Xiamen Port Holding is the controlling shareholder of the Company and XPDC is its wholly-owned subsidiary and therefore both are connected persons of the Company under the Listing Rules; (ii) XPDC is a substantial shareholder of Xiamen Sunstone; and (iii) the highest applicable Relevant Ratio in respect of the Subscription is more than 5% but less than 25%, the Subscription constitutes (a) a discloseable transaction of the Company as a deemed acquisition of equity interest in Xiamen Sunstone from its existing shareholders and is subject to the requirements for notification and announcement under Chapter 14 of the Listing Rules; and (b) a connected transaction of the Company by virtue of Rule 14A.28 of the Listing Rules and is subject to the requirements for notification, announcement and approval by the Independent Shareholders at the EGM.

22 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

PRINCIPAL FACTORS AND REASONS CONSIDERED In arriving at our opinion and recommendation in relation to the Subscription pursuant to the Subscription Agreement, we have considered the following principal factors and reasons:

1. Background of the Group The Group is the largest port terminal operator in Xiamen City, Fujian Province, the PRC. It is also the only group providing full-scale port integrated logistics services in Xiamen City. The Group is principally engaged in, inter alia, (i) container loading and unloading and storage for international and domestic trade; (ii) bulk/general cargo loading and unloading and storage for international and domestic trade; (iii) port integrated logistics services, including shipping agency, tallying, tugboat- assisted berthing and unberthing and port-related logistics; as well as (iv) the manufacturing, processing and selling of building materials and the trading of merchandise, in Xiamen City. The H Shares have been listed on the Main Board of the Stock Exchange since 19 December 2005.

Xiamen Port Development is a joint stock limited company established in the PRC, whose A shares are listed on the Shenzhen Stock Exchange since April 1999 and is currently held as to 61.89% by the Company as at the Latest Practicable Date. It is principally engaged in the provision of the loading/unloading and storage of bulk/general cargo, port integrated logistics services (including shipping agency, tugboat services, transportation services, tallying services and other ancillary extended services), trading services of commodities, as well as the sale of building materials in Xiamen City.

In respect of financial performance of the Group, the Group’s revenue amounted to approximately RMB13,933.1 million for the financial year ended 31 December (“FY(s)”) 2019, representing an increase of approximately 7.9% as compared to that of approximately RMB12,916.8 million in the FY 2018; while its net profit amounted to approximately RMB668.8 million for the FY 2019, representing an increase of approximately 20.6% as compared to that of approximately RMB554.4 million in the FY 2018. The profit attributable to owners of the Company amounted to approximately RMB279.7 million for the FY 2019, representing an increase of approximately 14.3% as compared to that of approximately RMB244.8 million in the FY 2018 mainly due to the increase in revenue from its merchandise trading business.

2. Background of Xiamen Port Holding Xiamen Port Holding Xiamen Port Holding is a wholly state-owned enterprise established in the PRC, and the controlling shareholder of the Company holding 1,862,464,000 Shares, representing approximately 68.32% shareholding interest in the Company as at the Latest Practicable Date.

It is principally engaged in, inter alia, (i) management and operation of certain state-owned assets; (ii) investment in different areas such as port, terminal, logistics, information, real estate, hotel, property, tourism and trading; (iii) providing financing; (iv) investment in financial institutions; (v) port development; (vi) environmental consultancy services in respect of sea pollution; (vii) information products development; and (viii) providing other port-related services.

To the best of the Board’s knowledge, information and belief, having made all reasonable enquiries, the ultimate beneficial owner of Xiamen Port Holding is the Xiamen SASAC, which is the

23 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER authority for supervision and administration of state-owned assets in Xiamen City, Fujian Province, the PRC.

XPDC XPDC is an indirect wholly-owned subsidiary of the Xiamen Port Holding held through XPCG (a wholly-owned subsidiary of Xiamen Port Holding), which is principally engaged in, inter alia, (i) comprehensive land development; (ii) development and construction management of ports, roads and ancillary works; (iii) sale of building materials; and (iv) project construction management technical consultation, etc..

3. Reasons for and benefits of entering into the Subscription Agreement As mentioned in the “Letter from the Board” of the Circular (the “Board Letter”), given that the Target Company (which is a non-wholly-owned subsidiary of the Group) and Xiamen Sunstone are both involving in the business of manufacturing, production and sale of commodity concrete and other cement-related products principally conducted in the region of Xiamen, the Board is of the view that the Equity Transfer and the Subscription as a whole would in effect integrate the Target Company into Xiamen Sunstone and provide the following benefits to the Group:

A. Optimisation of investment structure and financial performance Given that (i) the Group expects to recognise a gain of approximately RMB32,880,000 from the Equity Transfer before deduction of relevant expenses arising therefrom to be incurred by Xiamen Port Development; and (ii) the Target Company’s profitability is lower than Xiamen Sunstone as the average net asset rates of return of the Target Company and Xiamen Sunstone for the three years between 2017 and 2019 amounted to approximately 5.5% and 13.8% respectively, and therefore the profitability of the Target Company is lower than Xiamen Sunstone, the Board is of the view that, through the abovementioned integration, the Group expects to enhance its investment return and is able to secure a foreseeable and more stable source of income in reliance on the superior bargaining power of Xiamen Sunstone in Xiamen based on its sound, valuable and local hands-on commercial experience and significant economies of scale, as well as beneficial to the Group to further pool its resources for developing port-related business.

B. Enhancement of business competitiveness of the concrete and cement-related products The Group and XRBG intend to utilise Xiamen Sunstone as a unified platform to solidify its market position as the leading corporation in the concrete industry in Xiamen and Fujian Province and hence further improve its overall operating efficiency and competitiveness in the local and periphery commodity concrete and cement-related product market through optimisation of business structure and supply of quality and cost-effective products via reasonable resource integration and deployment in order to expand the concrete-related business in a joint effort.

C. Obtaining future listing dividend of Xiamen Sunstone and promoting asset securitisation Xiamen Sunstone is planning its initial public offering (“IPO”) and has been entered the pre-listing tutoring period since July 2018. In the event of the successful listing of Xiamen Sunstone, the Group could, by way of the Equity Transfer and the Subscription, dispose of the Target Company (which has a lower profitability than Xiamen Sunstone) in exchange for its role as a pre-IPO strategic

24 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER investor of Xiamen Sunstone so as to obtain the equity interest premium income that may be generated after the successful listing of Xiamen Sunstone in the future for promoting the asset securitisation of the members of the Group. To the best of the Board’s knowledge, information and belief, having made all reasonable enquiries, Xiamen Sunstone intends to strive for the lodging of a formal listing application at the China Securities Regulatory Commission by end of 2021.

The Directors (including all the independent non-executive Directors) have approved the entering into of the Equity Transfer Agreement and the Subscription Agreement and the transactions contemplated thereunder. Despite the Equity Transfer and the Subscription as a whole shall be regarded as a one-off corporate restructuring exercise which would not fall within the ordinary and usual course of business of the Group, the Directors have considered the terms of the Equity Transfer Agreement and the Subscription Agreement and are of the view that the same are on normal commercial terms, fair and reasonable and in the interests of the Group and the Shareholders as a whole.

Based on the above background information, we are of the view that it is commercially justifiable for conducting the Subscription by way of a one-off corporate restructuring exercise between the Group and Xiamen Sunstone, which is in the interests of the Group and the Shareholders as a whole, even though the Subscription itself is not conducted in the ordinary and usual course of business of the Group.

27 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

The Subscription Consideration The Subscription Consideration of RMB129,507,458 for the Subscription Shares was determined by Xiamen Port Development, Xiamen Sunstone and XRBG in good faith after arm’s length negotiation with reference to the following: (i) the appraised value of the entire equity interest of Xiamen Sunstone of RMB1,462,700,000 as at the Benchmark Assessment Date appraised by the PRC Qualified Valuer and as approved by Xiamen SASAC, by adopting an income approach; (ii) the net asset value of Xiamen Sunstone of RMB691,053,867 at company level as at 31 December 2019 as audited by the PRC Qualified Auditors pursuant to the Chinese Enterprise Accounting Standards; and (iii) the conditions of the operating assets, as well as the profitability and funding needs of Xiamen Sunstone.

Upon the Subscription Completion, out of the Subscription Consideration, RMB8,854,000 and RMB120,653,458 will be applied to the registered capital (on the basis of the nominal value per Subscription Share at RMB1.00 and the issue price at approximately RMB14.63 per Subscription Share) and the capital reserve of Xiamen Sunstone respectively.

Basis for determination of the Subscription Consideration The Subscription Consideration is basically consistent with the Appraised Value attributable to the 8.10% of the enlarged shareholding interest to be subscribed for by Xiamen Port Development.

The Appraisal Value was eventually calculated and arrived at based on the income approach and the general industry standards recognised and adopted nationally, which was further verified and approved by Xiamen SASAC. The PRC Qualified Valuer has considered, but did not adopt, the asset- based approach for evaluating the value of Xiamen Sunstone in view of its business nature as being principally engaged in (i) production of commodity concrete; and (ii) manufacturing of cement, cement products and building materials in the PRC, instead of an asset-based company. As such, we concur with the PRC Qualified Valuer’s decision not to adopt the asset-based approach for the Appraisal, and rather consider that the income approach is an appropriate methodology used in the Appraisal for Xiamen Sunstone. Please refer to the Board Letter and the Appraisal Report as set out in Appendix I to the Circular for fuller details of the underlying bases and assumptions adopted therein.

According to the appraisal reports of each of Xiamen Sunstone and the Target Company, the respective appraised value of each of their entire equity interest as at the Benchmark Assessment Date by adopting the income approach and the asset-based approach are as follows:

Xiamen Target Sunstone Company RMB RMB By income approach ...... 1,462,700,000 136,400,000 By asset-based approach ...... 1,201,861,400 132,232,000 Deviation ...... 260,838,600 4,168,000

As set out in the Appraisal Report as set out in Appraisal I to the Circular, there is a difference of RMB260,838,600 between the valuation results of the entire equity interest of Xiamen Sunstone by

28 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER adopting the income approach and the asset-based approach respectively, representing approximately 17.8% of the appraised value of the entire equity interest of Xiamen Sunstone. The Board understands from the PRC Qualified Valuer that the main reason for such discrepancy is that the assessment mentality of the asset-based approach is to reflect the replacement cost of the existing assets of an enterprise by first aggregating the appraised values of its asset and then deducting the appraised values of its liabilities, while the consideration perspective of the income approach is to reflect the present quantitative value of the comprehensive future profitability of the entire assets of an enterprise after taken into account of intangible factors that may significantly affect its future income, such as production techniques, asset condition, operation and management capability, sale and distribution network and goodwill.

In addition, to the best of the Directors’ knowledge, information and belief, having made all reasonable enquiries, as at the Latest Practicable Date, (i) the houses and buildings with incomplete or defective valuation information (such as ownership) as identified in each of the appraisal reports of Xiamen Sunstone and the Target Company (the “Defective Properties”) are occupied by the respective entity as leased properties merely used as ancillary infrastructure or fixtures, which would have no material impact on the production and business operation of Xiamen Sunstone or Target Company; and (ii) there has not been any dispute with, or any title claim by, any third party against the landlords as to the Defective Properties, which might affect the continuous occupation of the Defective Properties by Xiamen Sunstone or the Target Company. Accordingly, the Board considers that the normal business operations of Xiamen Sunstone after the Subscription Completion (including the Target Group) would not be affected without such land use right certificates and building ownership certificates in respect of the Defective Properties. Based on such consideration, we concur with the Directors’ view in this regard.

Xiamen Sunstone is the leading corporation in the concrete industry in Xiamen and Fujian Province and hence enjoys a competitive edge in the production of commodity concrete and manufacturing of cement and cement products in the local and provincial markets. The Board understands from the PRC Qualified Valuer that as (i) the operation, management and business performance of Xiamen Sunstone have steadily carried out year-by-year; (ii) the net profits of Xiamen Sunstone have demonstrated a significant upward trend over the last three years; and (iii) the main source of revenue and expected annual income of Xiamen Sunstone are recurring and are relatively stable, predictable and quantifiable, the PRC Qualified Valuer considered that the adoption of the income approach over the asset-based approach could better reflect the intrinsic value of Xiamen Sunstone in an objective manner.

Based on our independent due diligence work performed as detailed below, we concur with the PRC Qualified Valuer’s consideration and final selection of valuation approach and methodology to be adopted in the Appraisal Report.

We have independently reviewed the Appraisal Report on Xiamen Sunstone and understood from the PRC Qualified Valuer regarding, among other things, the bases and assumptions made and the methodology adopted by the PRC Qualified Valuer in conducting the appraisal for the business value as well as major assets of Xiamen Sunstone.

During the course of our independent review on the Appraisal Report and further understanding from/enquiry with the PRC Qualified Valuer, we have not identified any major factors which cause us to doubt the fairness and reasonableness of the principal bases and assumptions adopted for the asset appraisal works in relation to the Appraisal Report.

29 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Income approach is a valuation approach which discounts the expected future revenue of the target enterprise/ assets into present value with specific discount rates for the purpose of determining its/ their values. The inherit value of the target enterprise/ assets (i.e. their future profitability) is the basis of the income approach. The PRC Qualified Valuer considers that income approach is the most appropriate method in valuing Xiamen Sunstone as income approach focuses on the economic benefits generated by the income producing capability of an enterprise, and discounts these benefits to its present value using a discount rate appropriate for the risks associated with realising those benefits. Under the income approach, the discounted cash flow (“DCF”) method was adopted.

When applying DCF method to estimate the present market value of Xiamen Sunstone, it is necessary to determine an appropriate discount rate for the enterprise and its assets under review. Based on our independent review on the Appraisal Report and understanding from the PRC Qualified Valuer, the “weighted average cost of capital” (“WACC”) model has been used as the discount rate in the Appraisal. WACC is mainly comprised of two components, namely the cost of equity and the cost of debt. As mentioned in the Appraisal Report and advised by the PRC Qualified Valuer, the cost of debt amounts to 4.9%, which was the long-term (over 5 years) lending rate as stipulated by the People’s Bank of China as at the Benchmark Assessment Date (i.e. 31 December 2019).

With respect to the cost of equity, we were given to understand that the “capital asset pricing model” (“CAPM”) was used by the PRC Qualified Valuer. We understand that the CAPM technique is widely accepted in the investment and financial analysis communities for the purpose of estimating an enterprise’s required rate of return on equity. According to the CAPM, the cost of equity is equivalent to the risk-free rate plus the enterprise-specific risk adjustment co-efficient plus a linear function of a measure of systematic risk (“Beta”) times the market risk premium for the PRC. Based on our discussion with the PRC Qualified Valuer, it has adopted the applicable risk-free rate of approximately 3.14%, which was equivalent to the yield to maturity rate of PRC government bonds with remaining maturity of over 10 years as at the Benchmark Assessment Date.

According to the PRC Qualified Valuer, Beta, being a measure of the relationship between risk and the aggregate market, was determined after considering comparable companies identified by the PRC Qualified Valuer on its best effort and unbiased selection basis. After discussing with the PRC Qualified Valuer, we understand that it had researched for three listed companies, namely 深圳市天 地(集團)股份有限公司 (Shenzhen Universe Group Co., Ltd.) (stock code: 000023), 中建西部建設股份有 限公司 (China West Construction Group Co., Ltd.) (stock code: 002302) and 重慶三聖實業股份有限公 司 (Chongqing Sansheng Industrial Co., Ltd.) (stock code: 002742), which are engaged in the manufacturing construction material industry in the PRC, and consistent with our independent searching results from the Bloomberg data portal. We have interviewed the PRC Qualified Valuer to assess the fairness and reasonableness of the Beta, and concur with its view that the factors for determining the Beta used in the Appraisal are in line with market practice. As such, we are of the view that it is fair and reasonable to derive Beta from these peer companies. With the above determining factors, the PRC Qualified Valuer has finally determined the discount rate projected for future cash inflow in the Appraisal as 12.18% (which is calculated as: 81.66% x 14.09% + 18.34% x (1 – 25%) x 4.90% = 12.18%), which we consider to be appropriate, fair and reasonable.

We note that the PRC Qualified Valuer has considered and relied to a considerable extent on the financial forecast provided by Xiamen Sunstone when preparing the Appraisal. Based on the discussion with the PRC Qualified Valuer, it has believed that the forecast of those data is reasonable after considering the market trend of the industry and historical performance of Xiamen Sunstone. We

30 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER have interviewed with the PRC Qualified Valuer regarding the basis of projecting financial data of Xiamen Sunstone and other relevant assumptions. Pursuant to Rule 13.80 of the Listing Rules, in order to review and understand fairness, reasonableness and completeness the relevant assumptions and projections used in the Appraisal, we have performed the following steps: (i) discussed with the PRC Qualified Valuer and reviewed on the major items of the projection (including but not limited to the forecast operating revenue, operating costs, selling expenses and management expenses) provided by Xiamen Sunstone; (ii) reviewed the projection schedules built by the PRC Qualified Valuer and the related breakdowns; (iii) reviewed the audited financial statements and unaudited management accounts of Xiamen Sunstone for the two years ended 31 December 2019 and for the eight months ended 31 August 2020 and the related financial breakdowns; (iv) discussed with the PRC Qualified Valuer and reviewed on the industry trend of commodity concrete and construction materials in the PRC; and (v) reviewed other relevant bases and assumptions adopted in the Appraisal.

We have noted that (i) the historical growth rate of operating revenue of Xiamen Sunstone; (ii) the historical cost structure and growth trend of operating costs of Xiamen Sunstone; and (iii) the industry trend of commodity concrete and construction materials in the PRC supported the projection of operating revenue and operating costs of the Appraisal.

In view of the projection of operating revenue of Xiamen Sunstone, we understand the projection from the Appraisal is based on the estimation of the revenue amount substantially derived from sales of commodity comment products in its core business operation. For the projected growth rate, the PRC Qualified Valuer had made reference to the historical operating revenue and the future development plan of Xiamen Sunstone, and that the financial resources and business operation will continue to maintain as in current conditions. The growth rate of the operating revenue for the first few Years from 2020 to 2024 is expected to steadily increase by approximately 0.7% to 2.7% per annum with a compound annual growth rate (“CAGR”) of about 1.7%, while the same for the following years until perpetual is anticipated to be routine and stable with no growth for prudent sake.

The main operating costs of Xiamen Sunstone are the cost on purchasing raw materials for production of commodity cement products for its core business. In view of the operating costs, we understand that the projection from the Appraisal was calculated based on the projected operating revenue and a stable gross profit margin at an average of approximately 16.7% for the commodity cement business for the five Years from 2020 to 2024, which is basically consistent with the historical gross profit margin of around 16.6% for the Year 2019, and therefore we consider to be appropriate, fair and reasonable.

We have further reviewed the underlying calculation and understand that the selling expenses and management expenses of Xiamen Sunstone are mainly comprised of staff costs and other office expenses. The projection from the Appraisal is based on either (i) a stable growth rate; or (ii) a stable ratio of the operating income. Such projection is based on historical financial data of Xiamen Sunstone and the discussion with the management of Xiamen Sunstone. Staff costs are mainly comprised of staff wages, employee benefits, social security costs and housing provident fund costs. The components of projected selling costs and management costs are consistent with those of the historical records for the

31 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER past five Years from 2015 to 2019. Based on our review of the Appraisal Report and understanding from the PRC Qualified Valuer, the projected growth rate of selling expenses and management expenses was estimated based on a CAGR of around 2.3% and 2.5%, respectively, per annum with reference to the prevailing inflation rate.

Based on our independent researches for statistical information as extracted from the official websites of 中華人民共和國國家統計局 (The National Bureau of Statistics of China) at http://www.stats.gov.cn and https://data.stats.gov.cn, we noted that the overall consumer price index of the PRC as a whole and Xiamen City accounted for around 2.9% and 3.0%, respectively, in the Year 2019. On such basis, we consider that the projected annual growth rates/ CAGR in respect of Xiamen Sunstone’s operating revenue, operating costs, selling expenses and management expenses are realistic and prudent, and therefore fair and reasonable. After reviewing the historical financial data and discussion with the PRC Qualified Valuer, we believe that the growth of the components of the selling expenses and management expenses are relatively stable and correlated. As a result, we concur with the bases and assumptions adopted in the Appraisal to be fair and reasonable.

Based on our independent due diligence work performed as set out above, we are not aware of any factors which would cause us to doubt the fairness, reasonableness and completeness on the relevant bases and assumptions and projections used in the Appraisal.

Pursuant to Rule 13.80 of the Listing Rules, in order to assess the expertise and independence of the PRC Qualified Valuer regarding to the Appraisal, we have performed the following steps: (i) obtained and reviewed the terms of engagement (having particular regard to the scope of work, whether the scope of work is appropriate to the opinion required to be given and any limitations on the scope of work which might adversely impact on the degree of assurance given by the Appraisal Report); (ii) interviewed the PRC Qualified Valuer as to their current or prior relationships with the Company, and their respective shareholders; (iii) reviewed and discussed with the PRC Qualified Valuer on its qualifications and experience in relation to the preparation of the Appraisal; and (iv) enquired into the steps and due diligence measures taken by the PRC Qualified Valuer for conducting the Appraisal.

Based on our independent research from the public website of 中國證券監督管理委員會 (China Securities Regulatory Commission of the PRC) (the “CSRC”) at http://www.csrc.gov.cn, we noted that the PRC Qualified Valuer is one of the 70 qualified asset appraisal firms authorised by the CSRC and 中華人民共和國財政部 (the Ministry of Finance of the PRC) to perform asset appraisal works in the PRC. It has possessed sufficient qualifications and experience in valuing assets similar to that of Xiamen Sunstone for listed companies in the PRC and Hong Kong over the years. The PRC Qualified Valuer has also confirmed that except for its current engagement in respect of the Appraisal, it has no current or prior relationships with the Group, Xiamen Port Holding, Xiamen Sunstone or their respective equity/share-holders. As such, we are satisfied with the terms of engagement of the PRC Qualified Valuer and are not aware of any matters that would cause us to doubt the PRC Qualified Valuer’s expertise and independence in conducting the Appraisal.

Based on the due diligence work performed as set out above, we consider that we have made adequate assessment on the Appraisal in respect of the Appraisal Report and the PRC Qualified Valuer

32 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER pursuant to Rule 13.80 of the Listing Rules. During the course of our independent review on the Appraisal Report and further understanding from/enquiry with the PRC Qualified Valuer, we have not identified any major factors which cause us to doubt the fairness and reasonableness of the principal bases and assumptions adopted for the asset appraisal works in relation to the Appraisal Report. Nevertheless, Independent Shareholders should note that since the Appraisal involves various bases and assumptions, it may or may not accurately reflect the actual value of Xiamen Sunstone in the foreseeable future.

Taking into account that the Consideration is basically consistent with (i) the share of the Appraised Value under the Subscription, whereby the Appraisal is fairly and reasonably estimated by the PRC Qualified Valuer; and (ii) the pro-rata basis for calculating the consideration of RMB6,816,182 payable by XRBM (which is an independent third party) to subscribe for 0.43% shareholding interest in Xiamen Sunstone in exchange for its original 5% equity holding in the Target Company, we are of the opinion that the basis for determination of the Consideration is on normal commercial terms, fair and reasonable so far as the Independent Shareholders are concerned, and in the interests of the Group and the Shareholders as a whole.

Comparison with other companies in the similar industry As mentioned above, both the Target Company and Xiamen Sunstone are involving in the business of manufacturing, production and sale of commodity concrete and cement-related products principally in the Xiamen region, whilst the primary aim of the Equity Transfer and the Subscription, in substance, is a corporate restructuring exercise for enhancing their future business development potential.

In order to further assess the fairness and reasonableness of determining the Subscription Consideration, we have independently researched from the Bloomberg data portal and identified certain companies which are principally engaged in the construction material industry whose shares are listed on the Shanghai/ Shenzhen Stock Exchange of the PRC (the “Comparables”). However, having reviewed the` financial information and market capitalisation of such Comparables, we consider that direct comparison in terms of P/E Ratio and/or price-to-book ratio with such construction material companies listed on the Shanghai/ Shenzhen Stock Exchange with much larger operating scale would not be meaningful, or even misleading, on the grounds that Xiamen Sunstone’s scale of operation are relatively limited in financial and geographical terms, which we consider it not directly comparable with other sizeable listed construction material companies. Furthermore, since Xiamen Sunstone is not an asset-based company, we consider that price-to-book ratio and asset-based valuation approach shall not be applicable to Xiamen Sunstone.

Nevertheless, it has been the general market practice/ perception that it is better to buy shares in companies with a lower P/E Ratio among companies in the same industry, because this means an investor is paying less for every dollar of earnings that he/ she receives. In that sense, a lower P/E Ratio is like a lower price tag, making it attractive to investors looking for a bargain.

For our present case, in considering whether determination of the Equity Transfer Consideration and the Subscription Consideration are fair and reasonable, we noted that the respective imputed P/E Ratios for the Target Company and Xiamen Sunstone are approximately 24.4 times and 8.8 times based on their latest audited consolidated financial statements for the FY 2019 and Appraised Values as at 31 December 2019, it may imply that the Group is utilising a less profitable company (i.e.

33 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER the Target Company) with a higher valuation in terms of P/E Ratio in exchange for a much more profitable and promising company (i.e. Xiamen Sunstone) with lower P/E Ratio at almost the same consideration which seems to be favourable to the Group on the basis that the PRC Qualified Valuer has applied the same valuation approach (i.e. income approach) in valuing the total enterprise value of each of the Target Company and Xiamen Sunstone at the same time. We advise the Independent Shareholders to compare the P/E Ratios thereunder between each other, while the difference in proportion of equity/ shareholding interests that are being transferred/ subscribed for therein is not directly relevant for consideration. Upon the Subscription Completion, the Target Equity (i.e. being the 95% equity interest in the Target Company) should have been transferred to Xiamen Sunstone. Since the Target Company had net profit of approximately RMB5.6 million for the FY 2019, the P/E Ratio attributable to Xiamen Sunstone by consolidating the financial results of the Target Company upon the Subscription Completion would slightly decrease to approximately 8.5 times as the earning base would have been enlarged.

Based on the above analysis and consideration, we are of the view that determination of the Subscription Consideration by making reference to the Appraised Value is an appropriate and reliable appraisal basis for Xiamen Sunstone.

Payment terms Within 10 working days after notice by Xiamen Sunstone pursuant to the Subscription Agreement, Xiamen Port Development shall by way of bank transfer pay the Subscription Consideration in a lump-sum to Xiamen Sunstone. It is currently intended that the Subscription Consideration will be fully funded by RMB129,507,458 out of the proceeds from the Equity Transfer at RMB129,580,000. According to the current consensus of the parties to the Subscription Agreement, the Subscription will be implemented after the Equity Transfer Completion.

We consider the payment terms are commercially practicable, fair and reasonable.

Conditions precedent and approvals The Subscription shall be subject to, among other things, the satisfaction of the following conditions (all could not be waived, save for part of condition precedent numbered (iv) below which may be waived by the unanimous agreement of the parties): (i) the approval of the Subscription by the internal decision making body of Xiamen Sunstone; (ii) the approval of the Subscription by the internal decision making body of Xiamen Port Development; (iii) the approval of the Subscription by the Board and the Independent Shareholders at the EGM; (iv) no existence of any prohibition or restriction on any party to complete the issue and subscription of the Subscription Shares under law, regulations and antecedent undertakings; and (v) the approval of the matters related to the Subscription by Xiamen SASAC.

As at the Latest Practicable Date, (a) conditions precedent numbered (i), (ii) and (v) have been fulfilled; and (b) none of the parties has intention to waive any other of the above-mentioned conditions precedent.

34 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Completion The completion date of the Subscription shall fall on the date of payment of the Subscription Consideration by Xiamen Port Development, from thereon Xiamen Port Development shall entitled to the shareholders’ rights and perform the shareholders’ obligation in accordance with its equity proportion, and shall be entitled to nominate one director in accordance with the requirements under the new articles of Xiamen Sunstone. Xiamen Sunstone shall, within 15 working days from the completion date of the Subscription, complete the changing procedures regarding the Subscription (including the change of the industrial and commercial registration for the change of shareholders and the members of the board for the new term) or the filing procedures.

Others Please refer to the Board Letter for other immaterial terms of the Subscription Agreement.

Based on the above analysis and consideration, we are of the view that the Subscription contemplated under the Subscription Agreement are on normal commercial terms, fair and reasonable so far as the Independent Shareholders are concerned, and are in the interests of the Company and the Shareholders as a whole.

6. Possible financial effects of the Subscription on the Group Earnings Upon the Subscription Completion, other than the immaterial relevant expenses to be directly incurred in the Subscription, there is no immediate material impact on earnings of the Group by the only reason of the Subscription itself. The Group expects to recognise a gain on disposal of approximately RMB32.9 million as a result of the Equity Transfer.

Working capital According to the Company’s interim report for the six months ended 30 June 2020 (the “Interim Report”), the Group had a working capital deficiency (i.e. total current assets of approximately RMB6,924 million, less total current liabilities of approximately RMB8,554 million) position and cash and cash equivalents as at 30 June 2020 amounted to approximately RMB1,631 million and RMB1,886 million respectively, representing a current ratio of about 80.9%, which showed that the Group’s working capital position as at 30 June 2020 was relatively tight.

As the Subscription Consideration of RMB129,507,458 will be entirely financed by the net proceeds from the Equity Transfer upon the Equity Transfer Completion, which therefore does not involve any additional cash outlay from the Group, its present working capital deficiency position would not deteriorate or be adversely affected by the Subscription only in material respect after the Subscription Completion.

Net asset value According to the Interim Report, the consolidated net asset value (excluding non-controlling interests) of the Group was approximately RMB5,695 million as at 30 June 2020. It is currently expected that there would not be material adverse impact solely as a result of the Subscription itself; whilst the gain on disposal of the Target Equity to be recognised upon the Equity Transfer Completion may enhance the consolidated net asset value of the Group.

35 LETTER FROM THE INDEPENDENT FINANCIAL ADVISER

Gearing position

As at 30 June 2020, the Group had interest-bearing borrowings and net asset value (excluding non-controlling interests) of approximately RMB7,446 million and RMB5,695 million, respectively, representing a relatively higher gearing ratio (which is calculated as total interest-bearing borrowings divided by the net asset value of the Group) of approximately 130.8%.

As no material extra cash outlay and/or new interest-bearing borrowings would be involved to finance the Subscription because it would be fully financed by the net proceeds from the Equity Transfer, it is currently anticipated that the gearing position of the Group would not deteriorate.

Conclusion

The Group is, in substance, using the 95% equity-interest in the less profitable Target Company in exchange for a 8.10% shareholding interest in a much more profitable and promising company (i.e. Xiamen Sunstone), which, based on our understanding, is in the process of preparing for listing in the A share market of the Shenzhen/Shanghai Stock Exchange.

In light of the foregoing financial effects of the Subscription on the earnings, working capital, net asset value and gearing position of the Group as a whole, we are of the view that the Subscription is fair and reasonable so far as the Independent Shareholders are concerned, and in the interests of the Group and the Shareholders as a whole.

RECOMMENDATION

Having taken into account the above principal factors and reasons, we are of the view that although the Subscription is not conducted in the ordinary and usual course of business of the Group as which shall be regarded a one-off corporate restructuring exercise, the Subscription Agreement are entered into on normal commercial terms, fair and reasonable so far as the Independent Shareholders are concerned, and in the interests of the Company and the Shareholders as a whole. Accordingly, we recommend the Independent Shareholders, and the Independent Board Committee to advise the Independent Shareholders, to vote in favour of the ordinary resolution to approve the Subscription and the transactions contemplated thereunder pursuant to the Subscription Agreement at the EGM.

Yours faithfully, For and on behalf of First Shanghai Capital Limited Nicholas Cheng Director

VII. Valuation Approaches (I) Selection of valuation approaches According to Article 17 of the Practice Guidelines for Asset Valuation—Enterprise Value, when performing any appraisal of enterprise value, the suitability of the three basic asset valuation methods, namely, the income approach, the market approach and the cost approach (asset-based approach) shall be analyzed based on the purpose of valuation, the subject of valuation, the type of the value, and the availability of information.

1. Analysis of applicability of income approach The income approach in valuation of enterprise value refers to the valuation method whereby the value of the subject of valuation is determined by capitalising or discounting the expected income. The specific methods used by the income approach include the dividend discount method and the discounted cash flow method. The valuers shall appropriately take into consideration the suitability of the income approach in reference to the enterprise’s historical operating conditions, the predictability of future income, and the adequacy of information collected for valuation. The use of income approach for the valuation of an enterprise is subject to 3 pre-conditions:

(1) The future expected income of the enterprise is predictable and can be measured with currency;

(2) The risks assumed by the enterprise relating to the expected income are also predictable and can be measured with currency;

(3) The number of years with prospective earnings is predictable.

—I-22— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE

In this valuation, future income and risks can be predicted according to the operation planning and operation capacity of the appraised entity, which meets the basic premises for adoption of income approach. Therefore, the income approach can be adopted for this valuation.

2. Analysis of applicability of market approach Market approach in valuation of enterprise value refers to the comparison between the subject of valuation and a comparable listed company or a comparable transaction in order to determine the value of the subject of valuation. Two commonly used methods in market approach are comparable listed company and comparable transaction.

Given that there are few transaction cases of enterprises in the same industry and of the same scale, and it is hard to obtain the operating and financial information of referential enterprises and cases, the market approach does not apply to this valuation.

3. Analysis of applicability of asset-based approach The asset-based approach in valuation of enterprise value is a valuation method by which the values of various assets and liabilities in and off the balance sheet of an enterprise are reasonably valuated based on the balance sheet of the appraised entity on the Benchmark Assessment Date so as to determine the value of the subject of valuation. According to the Practice Guidelines for Asset Valuation—Enterprise Value, in applying the asset-based approach, the valuer shall require the appraised entity to identify each asset and liability both on and off the balance sheet according to the accounting policies and business operation, and shall know that not every asset and liability can be identified and valued separately. The applicability of the asset-based approach should be considered when there are assets or liabilities which have a significant impact on the value of subject of valuation and are difficult to identify and value.

The assets of the appraised entity are common types of assets, and there are no assets or liabilities which have a significant impact on the value of subject of valuation and are difficult to identify and value. Given that the economic and technical parameters needed for the cost approach can be adequately drawn from the data collected, the asset-based approach can be adopted for this valuation. To sum up, the asset-based approach and income approach are adopted for this valuation.

(II) Introduction to asset-based approach Asset-based approach in valuation of enterprise value refers to a valuation approach that reasonably determines the value of the subject of valuation by evaluating the value of various assets and liabilities on and off the balance sheet of an enterprise on the basis of the balance sheet of the appraised entity on the Benchmark Assessment Date.

The valuation methods of various assets and liabilities are as follows:

1. Current assets (1) Monetary funds: including bank deposits For bank deposits, check the book balance with the bank statement, and issue a letter of inquiry to the bank to verify the correctness of the bank balance. The appraised value shall be determined according to the verified book value.

—I-23— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE

(2) Receivables Regarding the evaluation of receivables, the valuers should, after the receivables are verified correctly and on the basis of historical data and information learned from the investigation, make a concrete analysis of the amount, debt time and reason, recovery of payments, and borrowers’ funds, credit and management status, and adopt specific identification and aging analysis to evaluate the risk loss; if there is every reason to believe that the current accounts of affiliated enterprises can be fully recovered, evaluate the risk loss to 0; if there is strong evidence that the amounts are irrecoverable or are aged, evaluate the risk loss to 100%; for amounts which are very likely to be irrecoverable or it is difficult to determine the irrecoverable amount, evaluate the risk loss with reference to the method adopted by enterprise accountants in calculating bad debt reserves according to the aging analysis method.

(3) Inventories For inventories, its quantity as at the Benchmark Assessment Date shall be determined by checking the consistency among those accounts, understanding the storage condition and internal control system and conducting the sample testing based on detailed breakdown provided by the appraised entity.

Approaches on valuation of raw materials:

① The appraised value of normally used raw materials is determined based on the objective market price on the Benchmark Assessment Date.

② It is learnt that most of the idle and sluggish raw materials are mixer truck parts and loader parts, including clutch plates, cylinder liner sealing ring parts, cylinder piston repair kits and water tank radiator assemblies, etc. From the enterprise’s inventory management personnel, the raw materials are mixer truck and loader parts used in the factories. As the corresponding machinery and equipment have been idle, the corresponding parts have no use value and no recyclable value. Therefore, the appraised value is calculated as zero.

Turnover materials in stock: determined based on the objective market price on the Benchmark Assessment Date. As the carrying amount can basically reflect the objective market price on the Benchmark Assessment Date, the appraised value of turnover materials in stock is determined based on the verified book value.

2. Non-current assets (1) Buildings Approaches on valuation of fixed assets of buildings generally include comparison approach, income approach, cost approach, and so on. The market approach is suitable for valuation of major similar real estate transactions; the income approach is suitable for valuation of real estate with gains or potential gains; the cost approach is suitable for valuation of real estate under the circumstances that it is not appropriate to adopt the market approach or income approach for valuation without market basis or in case of insufficient market basis;

Therefore, this valuation is conducted under the replacement cost approach based on the purpose of valuation and the characteristics of the appraised fixed assets of buildings and on the assumption of continuous use.

—I-24— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE

The cost approach is a method to obtain the replacement price or reconstruction price of the subject of valuation at the time of valuation, and comprehensively determine the newness rate based on the service life of the buildings and on-site investigation of the buildings so as to estimate the reasonable price or value of the appraised buildings.

The calculation formula of the replacement cost approach is as follows:

Appraised value of buildings = complete replacement value × newness rate

(2) Fixed assets of equipment The valuers valuate most of the equipment under the replacement cost approach, and the vehicles under the replacement cost approach and market approach based on the investigation and analysis of data provided by the enterprise, the purpose of this valuation, the principle of continuous use, the market price as well as the characteristics of the appraised equipment.

① Approaches on valuation of equipment Appraised value = complete replacement value × newness rate

The complete replacement value of machinery and equipment consists of equipment purchase price, transportation and miscellaneous fees, installation and debugging cost, basic cost, other expenses, cost of capital, etc. According to the Circular of the Ministry of Finance and the State Administration of Taxation on Several Issues Concerning the Implementation of VAT Transformation Reform in China (Cai Shui [2008] No. 170), since 1 January 2009, the input tax incurred on purchase of fixed assets by general taxpayers of VAT may be credited from the output tax against special VAT invoices, special bills of payment of customs import VAT, and documents of settlement of transportation expenses in accordance with the relevant provisions of the Interim Regulations of the People’s Republic of China on Value-added Tax (No. 538 Decree of the State Council) and the Detailed Rules for Implementing the Interim Regulations of the People’s Republic of China on Value- added Tax (No. 50 Decree of the Ministry of Finance and the State Administration of Taxation). Therefore, the input VAT should be deducted from the complete replacement value of equipment.

The calculation formula of the complete replacement value:

Complete replacement value = equipment purchase price + transportation and miscellaneous input VAT מ fees + installation and debugging cost + basic cost + other expenses + cost of capital incurred on purchase of equipment

As the electronic equipment included in the scope of valuation does not need to be installed (or the seller is responsible for the installation) and the transportation cost is low, the complete replacement value is determined with reference to the purchase price of similar equipment under the prevailing market without considering the transportation and miscellaneous fees, installation cost, other expenses and cost of capital.

② Approaches on valuation of vehicles In this valuation on vehicles, the production vehicles and special operation vehicles are valuated under the cost approach according to the characteristics and usage of the vehicles; the

—I-25— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE passenger vehicles are valuated by analogy under the market approach. First, collect data through market surveys and take the market transaction prices of three or more comparable properties that are similar to the appraised subject as basis; then, make a comparative analysis according to the model, transaction date, transaction, usage, vehicle conditions, nature of work and other factors influencing the appraised subject and comparable properties, make technical adjustments to the differences to obtain the prices of the comparable properties of the appraised subject, and finally calculate the appraised value of the appraised subject via the arithmetic mean. The calculation formula is:

Prices of the comparable properties = transaction prices of the comparable properties × score of the model of the appraised vehicle/score of the models of the comparable properties × score of the transaction dates of the comparable properties/score of the transaction date of the appraised vehicle × score of the transaction of the appraised vehicle/score of the transaction of the comparable properties x score of the usage of the appraised vehicle/score of the usage of the comparable properties x score of the conditions of the appraised vehicle/score of the conditions of the comparable properties

(3) Construction in progress The valuers know the image progress of the construction in progress through on-site investigation, verify the various project expenditures incurred in the construction in progress according to the current quota standards for construction and installation projects, and know the payment progress. They also investigate the market prices of the main engineering materials consumed by the construction in progress, and think that the book expenditure amount is reasonable and the basis is sufficient, and the expenditure proportion is basically consistent with the image progress of the completion of the project. As the construction in progress included in the scope of this valuation has not officially commenced, the carrying amount is mainly the cost for purchase of some materials and design. The valuers take the residual value after removal of unreasonable expenditures as the appraised value upon verification of the accounts based on the composition of the book value.

After verification, there is no unreasonable part in the book value, thus the valuers confirm the appraised value according to the verified book value.

(4) Long-term equity investments There are 14 long-term equity investments included in the scope of this valuation. We first valuate all equity interests of shareholders of subsidiaries, and then multiply them by the shareholding ratio to obtain the appraised value of long-term equity investments.

(5) Other on-balance-sheet intangible assets Other intangible assets are mainly financial software, etc. After verification on site, the financial software is installed in the company’s office computers and can be used normally. Therefore, the verified book value is taken as the appraised value.

(6) Long-term deferred expenses The valuers checked the relevant financial accounting records and obtained relevant materials including contracts and invoices. They take the verified book value as the appraised value.

(7) Deferred income tax assets In valuation of deferred income tax assets, the valuers investigate and learn about the reasons for and formation of the difference, and verify whether the difference will result in a deductible amount when determining the taxable income during the period of asset recovery or payment of liabilities in the future and whether the calculated amount complies with the relevant provisions of the accounting system for business enterprises and tax law. They confirm the appraised value based on the deductible amount to be incurred on the precondition that the deferred income tax assets are true and complete upon verification.

3. Liabilities The scope of valuation covers various current liabilities declared in the enterprise valuation, including notes payable, accounts payable, advance receipts, employee compensation payable, taxes payable, dividends payable, other payables and other current liabilities. The valuer investigated and verified the enterprise’s liabilities, and took the amount of liabilities required to be actually borne as at the Benchmark Assessment Date as the appraised value of liabilities based on the verification.

(III) Introduction to income approach The income approach in valuation of enterprise value refers to the valuation method whereby the value of the subject of valuation is determined by capitalising or discounting the expected income. The specific methods used by the income approach include the dividend discount method and the discounted cash flow method.

Income approach is a method whereby the enterprise value is estimated by discounting the enterprise’s expected future cash flow to present value. In other words, the expected cash flow is discounted to present value by calculating the enterprise’s expected future cash flow and using a proper discount rate to attain the enterprise value. It is applied under the basic conditions that the enterprise has the foundation and condition for continuing operation with a stable correspondence between its operation and income, and its future incomes and risks are predictable and quantifiable. The key to use the discounted cash flow method lies in the prediction on the expected future cash flow, the objectivity and reliability of data collection and processing, etc. The valuation result is quite objective and easy to be accepted by the market when the predictions on the expected future cash flow are objective and fair and the discount rate is selected on a reasonable basis.

1. Valuation idea According to the situation of the due diligence and the asset composition and main business of the subject of valuation, the basic ideas of this valuation are:

(1) to calculate the expected income (net cash flow) of the assets and main business included in the scope of statements according to the changes in historical operating conditions and business types of recent years, and discount the same to attain the value of business assets;

(2) to separately calculate the value of surplus assets and other assets as at the benchmark date included in the scope of statements but not considered in the calculation of the expected income (net cash flow) and assets (liabilities) defined as non-operating assets (liabilities);

—I-27— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE

(3) to attain the value of equity capital (all equity interests of shareholders) of the subject of valuation after deducting the value of interest-bearing liabilities from the enterprise value of the subject of valuation calculated by adding the value of the above two assets.

2. Income approach model

(1) Cash flow model

The specific methods commonly used by the income approach include the dividend discount method and the discounted cash flow method. Upon comprehensive analysis, discounted cash flow method and Discounted Cash Flow – Free Cash Flow for the Firm, i.e. DCF-FCFF model, are used in this valuation based on the income approach.

(2) Income period and predictive period

In this valuation, it is assumed that the appraised entity is operated on an on-going basis and relevant income period is determined as a perpetual period. In other words, the income period is the infinite operating period based on the assumption on continuing operation.

Generally, in contrast to the poor accuracy of the predictions on forward income, recent income of the enterprise can be predicted in a relatively accurate manner. In this valuation, staged income discount model is adopted based on the situation of the appraised enterprise to divide the enterprise’s income period into predictive period and perpetual period. First, the cash flow of the respective years in the preliminary stage (from 1 January 2020 to 31 December 2024) is estimated; then, it is estimated that the income for the years after 2025 remain unchanged as compared with the data for 2024; and finally, all the expected incomes are discounted and added.

3. Basic formula

Value of all equity interests of shareholders = overall enterprise value – value of interest- bearing liabilities.

Of which: overall enterprise value = present value of the FCFF + surplus assets + non-operating assets – non-operating liabilities

Of which: FCFF = net profit + depreciation and amortization + after-tax interests of interest- bearing liabilities – capital expenditure – increase of working capital

(1) Overall enterprise value

Overall enterprise value equals the sum of the value of all equity interests of shareholders and the value of interest-bearing liabilities. According the enterprise’s asset allocation and usage, the overall enterprise value is calculated according to the following formula:

Overall enterprise value = value of operating assets + value of surplus assets + value of non-operating assets and liabilities

—I-28— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE

① Value of operating assets Operating assets refer to the assets and liabilities related to the enterprise production and operation and involved in the FCFF prediction after the Benchmark Assessment Date. Value of operating assets is calculated according to the following formula:

Of which: P: Value of the enterprise’s operating assets as at the Benchmark Assessment Date; th Ri: Expected FCFF for the i year after the Benchmark Assessment Date; Rn+1: FCFF during the perpetual period; r: Discount rate (weighted average cost of capital, WACC); n: Predictive period; i: The ith year of the predictive period.

② Non-consolidated-statement long-term equity investment Please refer to the appraised value determined based on the above valuation method of “Asset- based approach – Long-term equity investment”.

③ Value of surplus assets Surplus assets refer to the assets beyond the demand of the enterprise production and operation and not involved in the FCFF prediction as at the Benchmark Assessment Date.

④ Value of non-operating assets and liabilities Non-operating assets and liabilities refer to the assets and liabilities irrelevant to the enterprise production and operation and not involved in the FCFF prediction. It is analysed and calculated separately.

(2) Value of interest-bearing liabilities Interest-bearing liabilities refer to liabilities with interests required to be paid, including bank borrowings, securities issued, long-term payables under financial leases, etc. Interest-bearing liabilities also include some other financing capitals which should have had interests but no interests are paid due to the identity as a related party or for other reasons, such as other payables.

VIII. Implementation Process and Situation of Valuation Procedure Preliminary work for this valuation started from late February 2020, onsite inspection was conducted from March 2020 to April 2020, and valuation conclusion was made on 5 August 2020. The valuation procedure comprises five stages:

IX. Valuation Assumptions In this valuation, the valuer has followed the following valuation assumptions:

(I) General assumptions 1. Transaction assumption Transaction assumption assumes that all assets to be valued are already in the process of transaction, and the professional asset valuer carries out a valuation based on the transaction conditions of the assets to be valued in a simulated market. It is the most essential prerequisite for asset valuation.

2. Open market assumption Open market assumption refers to the assumption that the price of assets which can be freely traded on a fully competitive market is determined based on the judgements on the asset value of the independent buyers and the sellers under the certain market conditions of supply. It is an assumed explanation or restriction on the conditions for proposed entry into the market and effects on the assets under comparatively perfect market conditions.

Open market refers to a fully competitive market with numerous buyers and sellers, where the buyers and sellers are equal in status and have opportunities and time to get enough market information and the transactions between the buyers and sellers are based on free will and rationality rather than mandatory or restricted conditions. Both the buyers and sellers can rationally judge the function, usage, transaction price, etc. of the assets. Open market assumption is based on the fact that the assets can be bought and sold openly in the market.

3. Assumption on continuing operation Assumption on continuing operation refers to the assumption that the operating activities of an operating entity will continue and will not be suspended or terminated in the foreseeable future.

If an operating entity is formed with some assets and liabilities for a specific purpose and a certain function, assumption on continuing operation means that the operating entity will continue to perform the said function for the said specific purpose in the foreseeable future.

(II) Special assumptions 1. There will be no major changes in the current political, legal, financial, market or economic conditions of Mainland China or countries or regions that have a significant impact on the business of the appraised entity and its subsidiaries.

—I-30— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE

2. The operation and business of the appraised entity and its subsidiaries will not be severely interrupted by any force majeure event or uncontrollable and unpredictable factors, including but not limited to wars, military events, natural disasters or catastrophes (such as floods and typhoons), epidemics or serious accidents.

3. The management of the appraised entity and its subsidiaries are dutiful and responsible; there is no significant change in the existing scope of operation; the internal control system of the appraised entity and its subsidiaries is effective and complete, and the risk management measures are adequate and appropriate.

4. The basic information and financial information provided by the Principals is true, accurate and complete; each asset included in the scope of appraisal is true and accurate, and their ownership are clear, legal and complete and all belong to the appraised entity or its subsidiaries; the documents certifying ownership of the assets issued by the appraised entity and its subsidiaries are legal and valid.

5. The appraised entity and its subsidiaries have fully complied with the relevant national and local laws and regulations in force; all licenses, use permits, letters of consent or other legal or administrative authorization documents issued by relevant local and national government agencies or bodies for the use and operation of the assets of the appraised entity and its subsidiaries were used normally and in compliance with rules within the validity period as at the Benchmark Assessment Date.

6. All improvements made by the appraised entity to all relevant assets are in compliance with all relevant legal provisions and requirements under other legal, planning or engineering of the relevant competent authorities.

7. All significant and potential factors that may affect the value have been fully disclosed to us by the Principals.

In accordance with the requirements of asset appraisal, the asset appraisal professionals have determined that these assumptions are valid as at the Benchmark Assessment Date, and the appraisal professionals will not assume the responsibility of deriving different appraisal conclusions due to changes in the premises when the economic environment changes significantly in the future.

When the above assumptions are not established, the Asset Valuation Report shall be invalid except where the differences between the actual situation and the above assumptions are accurately quantifiable and easy to adjust, the Principals shall request the Appraisal Institution to make corresponding adjustments to the asset appraisal conclusion when the purpose of asset appraisal is achieved.

X. Appraisal Conclusion

In accordance with the national laws, rules, regulations and valuation standards on asset appraisal, and in line with the principles of independence, impartiality, science and objectivity, we applied the statutory and necessary procedures for asset appraisal and adopted the asset-based approach and the income approach to conduct field survey, market investigation, confirmation and appraisal calculations on the assets of Xiamen Road & Bridge Sunstone Co., Ltd. included in the scope of appraisal and concluded as follows:

(I) Valuation results of asset-based approach

The audited book value of assets is RMB1,578,823,100, and the appraised value is RMB2,089,630,700, representing an increase in value of RMB510,807,600 and an increase in percentage of 32.35%.

The audited book value of liabilities is RMB887,769,300, and the appraisal value is RMB887,769,300, with no appraisal increase or decrease.

The audited book value of the entire equity of shareholders is RMB691,053,800, and the appraised value is RMB1,201,861,400 representing an increase in value of RMB510,807,600 and an increase in percentage of 73.92%.

The valuation results are summarized as follows: Amount unit: RMB’0,000

—I-32— APPENDIX I VALUATION REPORT OF XIAMEN SUNSTONE

(II) Valuation results of income approach The audited book value of the entire equity of shareholders is RMB691,053,800. Upon valuation by the income approach, the appraised value of the entire equity of shareholders is RMB1,462,700,000, representing an increase in value of RMB771,646,200 and an increase in percentage of 111.66%.

(III) Analysis of the difference in the valuation results of the two approaches The difference between the valuation results of the income approach and the asset-based approach is RMB260,838,600. The main reasons for the difference are as follows:

1. The asset-based approach refers to the appraisal idea of determining the value of the appraisal object on the basis of the reasonable valuation of the sub-item asset value and liabilities of the enterprise, that is, the method to add the appraised value of various element assets that constitute the enterprise, and deduct the appraised value of liabilities to obtain the equity value of shareholders of the enterprise. The valuation result reflects the replacement value of the enterprise based on existing assets and liabilities.

2. The income approach is used to comprehensively consider the impact of the enterprise’s various factors such as production technology, asset status, operation management, marketing network, and goodwill on the value of the enterprise based on the perspective of the enterprise’s future profitability. It reflects the enterprise’s comprehensive profitability of various assets.

(IV) Final selection of valuation results The asset-based approach is used to appraise the value of the enterprise by evaluating the value of individual assets and considering the relevant liabilities based on the perspective of asset replacement. The asset-based approach used this time has conducted an in-depth investigation of the enterprise’s various assets, and used appropriate valuation methods to evaluate various assets. On the whole, this asset-based approach is comprehensive for the overall valuation of the enterprise, and highlights the key points without major omissions. Therefore, the valuation result of this asset-based approach fully reflects the market value of entrusted assets to a certain extent.

The income approach reflects the comprehensive profitability of the enterprise’s various assets from the perspective of the enterprise’s future profitability. The results of the income approach include the value of intangible resources that are difficult to measure and quantify in the enterprise’s financial statements, such as platforms, services, marketing, teams, qualifications, and customers. It can objectively and comprehensively reflect the value of an enterprise.

Based on the comprehensive consideration of the quality and quantity of data used by different valuation methods, appraisers believe that the valuation results of the income approach is more convincing based on the purpose of this valuation, so the valuation results of the income approach are used as the valuation conclusion of the entire equity of shareholders, that is, the entire appraisal equity value of shareholders of Xiamen Road & Bridge Sunstone Co., Ltd. is RMB ONE BILLION FOUR HUNDRED AND SIXTY-TWO MILLION SEVEN HUNDRED THOUSAND Only (RMB1,462,700,000).

The users of this asset valuation report should pay attention to the impact of special matters on the valuation conclusion when applying this valuation conclusion.

VII. Valuation Approaches (I) Selection of valuation approaches According to Article 17 of the Practice Guidelines for Asset Valuation—Enterprise Value, when performing any appraisal of enterprise value, the suitability of the three basic asset valuation methods, namely, the income approach, the market approach and the cost approach (asset-based approach) shall be analyzed based on the purpose of valuation, the subject of valuation, the type of the value, and the availability of information.

1. Analysis of applicability of income approach The income approach in valuation of enterprise value refers to the valuation method whereby the value of the subject of valuation is determined by capitalising or discounting the expected income. The specific methods used by the income approach include the dividend discount method and the discounted cash flow method. The valuers shall appropriately take into consideration the suitability of the income approach in reference to the enterprise’s historical operating conditions, the predictability of future income, and the adequacy of information collected for valuation. The use of income approach for the valuation of an enterprise is subject to 3 pre-conditions:

(1) The future expected income of the enterprise is predictable and can be measured with currency;

(2) The risks assumed by the enterprise relating to the expected income are also predictable and can be measured with currency;

(3) The number of years with prospective earnings is predictable.

In this valuation, future income and risks can be predicted according to the operation planning and operation capacity of the appraised entity, which meets the basic premises for adoption of income approach. Therefore, the income approach can be adopted for this valuation.

2. Analysis of applicability of market approach Market approach in valuation of enterprise value refers to the comparison between the subject of valuation and a comparable listed company or a comparable transaction in order to determine the value of the subject of valuation. Two commonly used methods in market approach are comparable listed company and comparable transaction.

Given that there are few transaction cases of enterprises in the same industry and of the same scale, and it is hard to obtain the operating and financial information of referential enterprises and cases, the market approach does not apply to this valuation.

3. Analysis of applicability of asset-based approach The asset-based approach in valuation of enterprise value is a valuation method by which the values of various assets and liabilities in and off the balance sheet of an enterprise are reasonably

— II-14 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY valuated based on the balance sheet of the appraised entity on the Benchmark Assessment Date so as to determine the value of the subject of valuation. According to the Practice Guidelines for Asset Valuation—Enterprise Value, in applying the asset-based approach, the valuer shall require the appraised entity to identify each asset and liability both on and off the balance sheet according to the accounting policies and business operation, and shall know that not every asset and liability can be identified and valued separately. The applicability of the asset-based approach should be considered when there are assets or liabilities which have a significant impact on the value of subject of valuation and are difficult to identify and value.

The assets of the appraised entity are common types of assets, and there are no assets or liabilities which have a significant impact on the value of subject of valuation and are difficult to identify and value. Given that the economic and technical parameters needed for the cost approach can be adequately drawn from the data collected, the asset-based approach can be adopted for this valuation. To sum up, the asset-based approach and income approach are adopted for this valuation.

(II) Introduction to asset-based approach Asset-based approach in valuation of enterprise value refers to a valuation approach that reasonably determines the value of the subject of valuation by evaluating the value of various assets and liabilities on and off the balance sheet of an enterprise on the basis of the balance sheet of the appraised entity on the Benchmark Assessment Date.

The valuation methods of various assets and liabilities are as follows:

1. Current assets (1) Monetary funds: including bank deposits

For bank deposits, check the book balance with the bank statement, and issue a letter of inquiry to the bank to verify the correctness of the bank balance. The appraised value shall be determined according to the verified book value.

(2) Receivables Regarding the evaluation of receivables, the valuers should, after the receivables are verified correctly and on the basis of historical data and information learned from the investigation, make a concrete analysis of the amount, debt time and reason, recovery of payments, and borrowers’ funds, credit and management status, and adopt specific identification and aging analysis to evaluate the risk loss; if there is every reason to believe that the current accounts of affiliated enterprises can be fully recovered, evaluate the risk loss to 0; if there is strong evidence that the amounts are irrecoverable or are aged, evaluate the risk loss to 100%; for amounts which are very likely to be irrecoverable or it is difficult to determine the irrecoverable amount, evaluate the risk loss with reference to the method adopted by enterprise accountants in calculating bad debt reserves according to the aging analysis method.

(3) Inventories For inventories, its quantity as at the Benchmark Assessment Date shall be determined by checking the consistency among those accounts, understanding the storage condition and internal control system and conducting the sample testing based on detailed breakdown provided by the appraised entity.

— II-15 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

Approaches on valuation of raw materials:

① The appraised value of normally used raw materials is determined based on the objective market price on the Benchmark Assessment Date.

② It is learnt that most of the idle and sluggish raw materials (including No. 51-53 of inventory—raw material appraisal list) are mixer truck parts and loader parts, including clutch plates, cylinder liner sealing ring parts, cylinder piston repair kits and water tank radiator assemblies, etc. From the enterprise’s inventory management personnel, the raw materials are mixer truck and loader parts used in the factories. As the corresponding machinery and equipment have been scrapped, so the corresponding parts have no use value; and as these parts have been left unused for a long time, the materials have expired, and the quality is not guaranteed, so there is no recyclable value. Therefore, the appraised value is calculated as zero.

The valuation method of turnover materials in stock:

Turnover materials in stock are determined based on the objective market price on the Benchmark Assessment Date. As the carrying amount can basically reflect the objective market price on the valuation benchmark date, the appraised value of turnover materials in stock is determined based on the verified book value.

The valuation method of finished goods:

The valuers analyse the finished goods based on the investigation and the information provided by the company, and determine the appraised value of the finished goods based on the tax-exclusive sales price after deducting sales expenses, all taxes and certain profits from product sales.

Appraised value = Actual quantity × tax-exclusive sales price × (1 – sales expense ratio – product sales tax and surcharge rates – operating profit margin × income tax rate – operating profit margin × (1 – income tax rate) × r)

a. Tax-exclusive sales price: The tax-exclusive sales price is determined according to the tax-exclusive price in the recent shipping order of each commodity or the list of sales price provided by the company;

b. Product sales tax and surcharge rates mainly include urban construction tax and education surcharge paid using value-added tax as tax base;

c. Sales expense ratio refers to the average ratio between sales expenses and sales revenue;

d. Operating profit margin = main operating profit ÷ main operating income;

e. Income tax rate is subject to currently executed tax rate of the enterprise;

f. r is a certain rate. Since there are certain market risks and uncertainties for future sales of finished goods, such risks are determined based on the surveys on the benchmark date and the sales after the benchmark date. In addition, r is zero for marketable products, 50% for general sales products, and 100% for barely salable products.

— II-16 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

2. Non-current assets (1) Buildings Approaches on valuation of fixed assets of buildings generally include comparison approach, income approach, cost approach, and so on. The market approach is suitable for valuation of major similar real estate transactions; the income approach is suitable for valuation of real estate with gains or potential gains; the cost approach is suitable for valuation of real estate under the circumstances that it is not appropriate to adopt the market approach or income approach for valuation without market basis or in case of insufficient market basis;

Therefore, this valuation is conducted under the replacement cost approach based on the purpose of valuation and the characteristics of the appraised fixed assets of buildings and on the assumption of continuous use.

The cost approach is a method to obtain the replacement price or reconstruction price of the subject of valuation at the time of valuation, and comprehensively determine the newness rate based on the service life of the buildings and on-site investigation of the buildings so as to estimate the reasonable price or value of the appraised buildings.

The calculation formula of the replacement cost approach is as follows:

Appraised value of buildings = complete replacement value × newness rate

(2) Fixed assets of equipment The valuers valuate most of the equipment under the replacement cost approach, and the vehicles under the replacement cost approach and market approach based on the investigation and analysis of data provided by the enterprise, the purpose of this valuation, the principle of continuous use, the market price as well as the characteristics of the appraised equipment.

① Approaches on valuation of equipment Appraised value = complete replacement value × newness rate

The complete replacement value of machinery and equipment consists of equipment purchase price, transportation and miscellaneous fees, installation and debugging cost, basic cost, other expenses, cost of capital, etc. According to the Circular of the Ministry of Finance and the State Administration of Taxation on Several Issues Concerning the Implementation of VAT Transformation Reform in China (Cai Shui [2008] No. 170), since 1 January 2009, the input tax incurred on purchase of fixed assets by general taxpayers of VAT may be credited from the output tax against special VAT invoices, special bills of payment of customs import VAT, and documents of settlement of transportation expenses in accordance with the relevant provisions of the Interim Regulations of the People’s Republic of China on Value-added Tax (No. 538 Decree of the State Council) and the Detailed Rules for Implementing the Interim Regulations of the People’s Republic of China on Value- added Tax (No. 50 Decree of the Ministry of Finance and the State Administration of Taxation). Therefore, the input VAT should be deducted from the complete replacement value of equipment.

— II-17 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

The calculation formula of the complete replacement value:

Complete replacement value = equipment purchase price + transportation and miscellaneous input VAT מ fees + installation and debugging cost + basic cost + other expenses + cost of capital incurred on purchase of equipment

As the electronic equipment included in the scope of valuation does not need to be installed (or the seller is responsible for the installation) and the transportation cost is low, the complete replacement value is determined with reference to the purchase price of similar equipment under the prevailing market without considering the transportation and miscellaneous fees, installation cost, other expenses and cost of capital.

② Approaches on valuation of vehicles

In this valuation on vehicles, the production vehicles and special operation vehicles are valuated under the cost approach according to the characteristics and usage of the vehicles; the passenger vehicles are valuated by analogy under the market approach. First, collect data through market surveys and take the market transaction prices of three or more comparable properties that are similar to the appraised subject as basis; then, make a comparative analysis according to the model, transaction date, transaction, usage, vehicle conditions, nature of work and other factors influencing the appraised subject and comparable properties, make technical adjustments to the differences to obtain the prices of the comparable properties of the appraised subject, and finally calculate the appraised value of the appraised subject via the arithmetic mean. The calculation formula is:

Prices of the comparable properties = transaction prices of the comparable properties × score of the model of the appraised vehicle/score of the models of the comparable properties × score of the transaction dates of the comparable properties/score of the transaction date of the appraised vehicle × score of the transaction of the appraised vehicle/score of the transaction of the comparable properties x score of the usage of the appraised vehicle/score of the usage of the comparable properties x score of the conditions of the appraised vehicle/score of the conditions of the comparable properties

(3) Construction in progress

The valuers know the image progress of the construction in progress through on-site investigation, verify the various project expenditures incurred in the construction in progress according to the current quota standards for construction and installation projects, and know the payment progress. They also investigate the market prices of the main engineering materials consumed by the construction in progress, and think that the book expenditure amount is reasonable and the basis is sufficient, and the expenditure proportion is basically consistent with the image progress of the completion of the project. As the construction in progress included in the scope of this valuation has not officially commenced, the carrying amount is mainly the cost for purchase of some materials and design. The valuers take the residual value after removal of unreasonable expenditures as the appraised value upon verification of the accounts based on the composition of the book value.

After verification, there is no unreasonable part in the book value, thus the valuers confirm the appraised value according to the verified book value.

— II-18 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

(4) Long-term equity investments There are three long-term equity investments included in the scope of this valuation. We first appraised the value of all equity interests of the three subsidiaries of Xiamen Port Hailuda Building Materials Co., Ltd. (廈門港務海路達建材有限公司), Xiamen Port Building Materials Supply Chain Co., Ltd. (廈門港務建材供應鏈有限公司) and Xiamen Jida Building Materials Technology Co., Ltd. (廈門集 大建材科技有限公司), and then multiply them by the shareholding ratio to obtain the appraised value of long-term equity investments.

(5) Other on-balance-sheet intangible assets Other intangible assets are mainly financial software, etc. After verification on site, the financial software is installed in the company’s office computers and can be used normally. The intangible assets included in the scope of this valuation are mainly financial software purchased by the company, which is a non-general entrusted customized type. It is difficult to find the market price of the same software in the market, and the software purchased by the company is mainly used for its own management and cannot generate income separately. The valuers spot checked the software purchase contracts and invoices, and believed that the value of the company’s carrying value was true, and the amortization period was determined by the company based on the expected service life of the software, and the company’s book value could reflect the use value of the software. The verified book value is confirmed as the appraised value.

(6) Long-term deferred expenses The appraisers found out the reasons for the occurrence of long-term deferred expenses, checked the accounting vouchers of long-term deferred expenses, and verified the date of occurrence of the expenses, the expected number of months of amortization, the number of amortized months, and the remaining months with benefits after the benchmark date. The long-term deferred expenses included in this valuation scope are mainly the renovation cost of the appraised entity on the lease assets. The benefit period is consistent with the expected amortization period of the company. The book value can reflect the subsequent value in use of this asset and the verified book value is taken as the appraised value.

(7) Deferred income tax assets In valuation of deferred income tax assets, the valuers investigate and learn about the reasons for and formation of the difference, and verify whether the difference will result in a deductible amount when determining the taxable income during the period of asset recovery or payment of liabilities in the future and whether the calculated amount complies with the relevant provisions of the accounting system for business enterprises and tax law. They confirm the appraised value based on the deductible amount to be incurred on the precondition that the deferred income tax assets are true and complete upon verification.

3. Liabilities The scope of valuation covers various current liabilities declared in the enterprise valuation, including notes payable, accounts payable, advance receipts, employee compensation payable, taxes payable, dividends payable, other payables and other current liabilities. The valuer investigated and verified the enterprise’s liabilities, and took the amount of liabilities required to be actually borne as at the Benchmark Assessment Date as the appraised value of liabilities based on the verification.

— II-19 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

(III) Introduction to income approach The income approach in valuation of enterprise value refers to the valuation method whereby the value of the subject of valuation is determined by capitalising or discounting the expected income. The specific methods used by the income approach include the dividend discount method and the discounted cash flow method.

Income approach is a method whereby the enterprise value is estimated by discounting the enterprise’s expected future cash flow to present value. In other words, the expected cash flow is discounted to present value by calculating the enterprise’s expected future cash flow and using a proper discount rate to attain the enterprise value. It is applied under the basic conditions that the enterprise has the foundation and condition for continuing operation with a stable correspondence between its operation and income, and its future incomes and risks are predictable and quantifiable. The key to use the discounted cash flow method lies in the prediction on the expected future cash flow, the objectivity and reliability of data collection and processing, etc. The valuation result is quite objective and easy to be accepted by the market when the predictions on the expected future cash flow are objective and fair and the discount rate is selected on a reasonable basis.

1. Valuation idea According to the situation of the due diligence and the asset composition and main business of the subject of valuation, the basic ideas of this valuation are:

(1) to calculate the expected income (net cash flow) of the assets and main business included in the scope of statements according to the changes in historical operating conditions and business types of recent years, and discount the same to attain the value of business assets;

(2) to separately calculate the value of surplus assets and other assets as at the benchmark date included in the scope of statements but not considered in the calculation of the expected income (net cash flow) and assets (liabilities) defined as non-operating assets (liabilities);

(3) to attain the value of equity capital (all equity interests of shareholders) of the subject of valuation after deducting the value of interest-bearing liabilities from the enterprise value of the subject of valuation calculated by adding the value of the above two assets.

2. Income approach model (1) Cash flow model The specific methods commonly used by the income approach include the dividend discount method and the discounted cash flow method. Upon comprehensive analysis, discounted cash flow method and Discounted Cash Flow – Free Cash Flow for the Firm, i.e. DCF-FCFF model, are used in this valuation based on the income approach.

(2) Income period and predictive period In this valuation, it is assumed that the appraised entity is operated on an on-going basis and relevant income period is determined as a perpetual period. In other words, the income period is the infinite operating period based on the assumption on continuing operation.

— II-20 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

Generally, in contrast to the poor accuracy of the predictions on forward income, recent income of the enterprise can be predicted in a relatively accurate manner. In this valuation, staged income discount model is adopted based on the situation of the appraised enterprise to divide the enterprise’s income period into predictive period and perpetual period. First, the cash flow of the respective years in the preliminary stage (from 1 January 2020 to 31 December 2024) is estimated; then, it is estimated that the income for the years after 2025 remain unchanged as compared with the data for 2024; and finally, all the expected incomes are discounted and added.

3. Basic formula Value of all equity interests of shareholders = overall enterprise value – value of interest- bearing liabilities.

Of which: overall enterprise value = present value of the FCFF + surplus assets + non-operating assets – non-operating liabilities

Of which: FCFF = net profit + depreciation and amortization + after-tax interests of interest- bearing liabilities – capital expenditure – increase of working capital

(1) Overall enterprise value Overall enterprise value equals the sum of the value of all equity interests of shareholders and the value of interest-bearing liabilities. According the enterprise’s asset allocation and usage, the overall enterprise value is calculated according to the following formula:

Overall enterprise value = value of operating assets + value of surplus assets + value of non-operating assets and liabilities

① Value of operating assets Operating assets refer to the assets and liabilities related to the enterprise production and operation and involved in the FCFF prediction after the Benchmark Assessment Date. Value of operating assets is calculated according to the following formula:

Of which: P: Value of the enterprise’s operating assets as at the Benchmark Assessment Date;

th Ri: Expected FCFF for the i year after the Benchmark Assessment Date;

Rn+1: FCFF during the perpetual period; r: Discount rate (weighted average cost of capital, WACC); n: Predictive period;

i: The ith year of the predictive period.

— II-21 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

② Non-consolidated-statement long-term equity investment Please refer to the appraised value determined based on the above valuation method of “Introduction to asset-based approach—Long-term equity investments”.

③ Value of surplus assets Surplus assets refer to the assets beyond the demand of the enterprise production and operation and not involved in the FCFF prediction as at the Benchmark Assessment Date.

④ Value of non-operating assets and liabilities Non-operating assets and liabilities refer to the assets and liabilities irrelevant to the enterprise production and operation and not involved in the FCFF prediction. It is analysed and calculated separately.

(2) Value of interest-bearing liabilities Interest-bearing liabilities refer to liabilities with interests required to be paid, including bank borrowings, securities issued, long-term payables under financial leases, etc. Interest-bearing liabilities also include some other financing capitals which should have had interests but no interests are paid due to the identity as a related party or for other reasons, such as other payables.

IX. Valuation Assumptions In this valuation, the valuer has followed the following valuation assumptions:

(I) General assumptions 1. Transaction assumption Transaction assumption assumes that all assets to be valued are already in the process of transaction, and the professional asset valuer carries out a valuation based on the transaction conditions of the assets to be valued in a simulated market. It is the most essential prerequisite for asset valuation.

2. Open market assumption Open market assumption refers to the assumption that the price of assets which can be freely traded on a fully competitive market is determined based on the judgements on the asset value of the independent buyers and the sellers under the certain market conditions of supply. It is an assumed explanation or restriction on the conditions for proposed entry into the market and effects on the assets under comparatively perfect market conditions.

Open market refers to a fully competitive market with numerous buyers and sellers, where the buyers and sellers are equal in status and have opportunities and time to get enough market information and the transactions between the buyers and sellers are based on free will and rationality rather than mandatory or restricted conditions. Both the buyers and sellers can rationally judge the function, usage, transaction price, etc. of the assets. Open market assumption is based on the fact that the assets can be bought and sold openly in the market.

3. Assumption on continuing operation Assumption on continuing operation refers to the assumption that the operating activities of an operating entity will continue and will not be suspended or terminated in the foreseeable future.

If an operating entity is formed with some assets and liabilities for a specific purpose and a certain function, assumption on continuing operation means that the operating entity will continue to perform the said function for the said specific purpose in the foreseeable future.

(II) Special assumptions 1. There will be no major changes in the current political, legal, financial, market or economic conditions of Mainland China or countries or regions that have a significant impact on the business of the appraised entity and its subsidiaries.

2. The operation and business of the appraised entity and its subsidiaries will not be severely interrupted by any force majeure event or uncontrollable and unpredictable factors, including but not limited to wars, military events, natural disasters or catastrophes (such as floods and typhoons), epidemics or serious accidents.

3. The management of the appraised entity and its subsidiaries are dutiful and responsible; there is no significant change in the existing scope of operation; the internal control system of the appraised entity and its subsidiaries is effective and complete, and the risk management measures are adequate and appropriate.

— II-23 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

4. The basic information and financial information provided by the Principals is true, accurate and complete; each asset included in the scope of appraisal is true and accurate, and their ownership are clear, legal and complete and all belong to the appraised entity or its subsidiaries; the documents certifying ownership of the assets issued by the appraised entity and its subsidiaries are legal and valid.

5. The appraised entity and its subsidiaries have fully complied with the relevant national and local laws and regulations in force; all licenses, use permits, letters of consent or other legal or administrative authorization documents issued by relevant local and national government agencies or bodies for the use and operation of the assets of the appraised entity and its subsidiaries were used normally and in compliance with rules within the validity period as at the valuation benchmark date.

6. All improvements made by the appraised entity to all relevant assets are in compliance with all relevant legal provisions and requirements under other legal, planning or engineering of the relevant competent authorities.

7. All significant and potential factors that may affect the value have been fully disclosed to us by the Principals.

In accordance with the requirements of asset appraisal, the asset appraisal professionals have determined that these assumptions are valid as at the valuation benchmark date, and the appraisal professionals will not assume the responsibility of deriving different appraisal conclusions due to changes in the premises when the economic environment changes significantly in the future.

When the above assumptions are not established, the Asset Valuation Report shall be invalid except where the differences between the actual situation and the above assumptions are accurately quantifiable and easy to adjust, the Principals shall request the Appraisal Institution to make corresponding adjustments to the asset appraisal conclusion when the purpose of asset appraisal is achieved.

X. Appraisal Conclusion In accordance with the national laws, rules, regulations and valuation standards on asset appraisal, and in line with the principles of independence, impartiality, science and objectivity, we applied the statutory and necessary procedures for asset appraisal and adopted the asset-based approach and the income approach to conduct field survey, market investigation, confirmation and appraisal calculations on the assets of Xiamen Road and Bridge Building Materials Co., Ltd. included in the scope of appraisal and concluded as follows:

(I) Valuation results of asset-based approach The audited book value of assets is RMB250,496,700, and the appraised value is RMB276,797,200, representing an increase in the appraised value of RMB26,300,500 and an increase in percentage of 10.50%.

The audited book value of liabilities is RMB144,638,700, and the appraised value is RMB144,565,200, representing a decrease in the appraised value of RMB73,500 and a decrease in percentage of 0.05%.

— II-24 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

The audited book value of all equity interests is RMB105,858,000, and the appraised value is RMB132,232,000, representing an increase in the appraised value of RMB26,374,000 and an increase in percentage of 24.91%.

The summary of appraisal results is as follows:

Monetary unit: RMB’0,000 Increase Appraised (decrease) Value-added Book value value in value rate % Item A B C=B-A D=C/A×100% 1 Current assets 19,241.19 19,441.40 200.21 1.04 2 Non-current assets 5,808.48 8,238.32 2,429.84 41.83 3 Among which: Long-term equity investment 2,961.52 5,103.60 2,142.08 72.33 4 Investment real estate — — — — 5 Fixed assets 2,082.83 2,437.19 354.36 17.01 6 Among which: Buildings 745.03 946.50 201.47 27.04 7 Equipment 1,337.81 1,490.69 152.88 11.43 8 Land — — — — 9 Construction in progress 123.66 123.66 — — 10 Intangible assets 25.67 25.67 — — 11 Among which: Land use rights — — — — 12 Development expenditures — — — — 13 Goodwill — — — — 14 Long-term deferred expenses 53.32 53.32 — — 15 Deferred income tax assets 561.47 494.87 -66.60 -11.86 16 Other non-current assets — — — — 17 Total assets 25,049.67 27,679.72 2,630.05 10.50 18 Current liabilities 14,463.87 14,456.52 -7.35 -0.05 19 Non-current liabilities — — — — 20 Total liabilities 14,463.87 14,456.52 -7.35 -0.05 21 Net assets (owner’s equities) 10,585.80 13,223.20 2,637.40 24.91

(II) Appraisal result of income approach The audited book value of all equity interests is RMB105,858,000. After appraised by using the income approach, the appraised value of all equity interests is RMB136,400,000, representing an increase in value of RMB30,542,000 and an increase in percentage of 28.29%.

(III) Analysis of the difference in the valuation results of the two approaches The difference between the valuation results of the income approach and the asset-based approach is RMB4,168,000. The main reasons for the difference are as follows:

1. The asset-based approach refers to the appraisal idea of determining the value of the appraisal object on the basis of the reasonable valuation of the sub-item asset value and liabilities of the enterprise, that is, the method to add the appraised value of various element assets that constitute the enterprise, and deduct the appraised value of liabilities to obtain the equity value of shareholders of the enterprise. The valuation result reflects the replacement value of the enterprise based on existing assets and liabilities.

— II-25 — APPENDIX II VALUATION REPORT OF THE TARGET COMPANY

2. The income approach is used to comprehensively consider the impact of the enterprise’s various factors such as production technology, asset status, operation management, marketing network, and goodwill on the value of the enterprise based on the perspective of the enterprise’s future profitability. It reflects the enterprise’s comprehensive profitability of various assets.

(IV) Final selection of valuation results The asset-based approach is used to appraise the value of the enterprise by evaluating the value of individual assets and considering the relevant liabilities based on the perspective of asset replacement. The asset-based approach used this time has conducted an in-depth investigation of the enterprise’s various assets, and used appropriate valuation methods to evaluate various assets. On the whole, this asset-based approach is comprehensive for the overall valuation of the enterprise, and highlights the key points without major omissions. Therefore, the valuation result of this asset-based approach fully reflects the market value of entrusted assets to a certain extent.

The income approach reflects the comprehensive profitability of the enterprise’s various assets from the perspective of the enterprise’s future profitability. The results of the income approach include the value of intangible resources that are difficult to measure and quantify in the enterprise’s financial statements, such as platforms, services, marketing, teams, qualifications, and customers. It can objectively and comprehensively reflect the value of an enterprise.

Based on the comprehensive consideration of the quality and quantity of data used by different valuation methods, appraisers believe that the valuation results of the income approach is more convincing based on the purpose of this valuation, so the valuation results of the income approach are used as the valuation conclusion of the entire equity of shareholders, that is, the appraised value of all equity interests of Xiamen Road and Bridge Building Materials Co., Ltd. is RMB ONE HUNDRED AND THIRTY-SIX MILLION AND FOUR HUNDRED THOUSAND ONLY (RMB136,400,000).

The users of this asset valuation report should pay attention to the impact of special matters on the valuation conclusion when applying this valuation conclusion.
