The Business Combination



On April 13, 2023 (the “Closing Date”),
the Company consummated the previously announced business combination pursuant to the Amended and Restate Agreement and Plan of Merger,
dated December 15, 2021, by and among (i) the Company, (ii) Bitdeer, (iii) BSGA, (iv) Blue Safari Merge Limited,
a British Virgin Islands business company and a wholly-owned subsidiary of the Company (“BSGA Merger Sub 1”), (v) Blue
Safari Merge II Limited, a British Virgin Islands business company and a wholly-owned subsidiary of the Company (“BSGA Merger Sub
2”), (vi) Bitdeer Merge Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands
and a wholly-owned subsidiary of the Company (“Bitdeer Merger Sub”) and (vii) Blue Safari Mini Corp., an exempted company
incorporated with limited liability under the laws of the Cayman Islands and a wholly-owned subsidiary of BSGA, as amended by (a) the
First Amendment to Amended and Restate Agreement and Plan of Merger, dated May 30, 2022, (b) the Second Amendment to Amended
and Restated Agreement and Plan of Merger, dated December 2, 2022 and (c) the Third Amendment to Amended and Restated Agreement
and Plan of Merger, dated March 7, 2023, each by and among the same parties (the “Merger Agreement”).













Pursuant to the Merger Agreement, the transactions
contemplated under the Merger Agreement were consummated via a multiple-merger structure, including (i) BSGA Merger Sub 1 merging
with and into BSGA with BSGA being the surviving entity and becoming a wholly-owned subsidiary of the Company (the “First SPAC Merger”,
and the surviving entity, the “Initial SPAC Surviving Sub”), (ii) immediately following the First SPAC Merger, Initial
SPAC Surviving Sub merging with and into BSGA Merger Sub 2, with BSGA Merger Sub 2 being the surviving entity (the “Second SPAC
Merger”, and together with the First SPAC Merger, the “Initial Mergers”), and (iii) following the Initial Mergers,
Bitdeer Merger Sub merging with and into Bitdeer, with Bitdeer being the surviving entity and becoming a wholly-owned subsidiary of the
Company (the “Acquisition Merger”, and together with the Initial Mergers and other transactions contemplated by the Merger
Agreement, the “Business Combination”).



Immediately prior to the effective time of the
First SPAC Merger (the “First SPAC Merger Effective Time”), (i) each unit of BSGA (“BSGA Unit”) issued and
outstanding immediately prior to the First SPAC Merger Effective Time was automatically detached into one Class A ordinary shares,
no par value, of BSGA (the “BSGA Class A Ordinary Share”) and one right convertible into one-tenth (1/10) of a BSGA Class A
Ordinary Share (the “BSGA Right”) and (ii) each BSGA Right outstanding immediately prior to the First SPAC Merger Effective
Time (and immediately subsequent to the detachment of the BSGA Units) was cancelled and ceased to exist in exchange for the right to receive,
without interest, one-tenth (1/10) of a BSGA Class A Ordinary Share.



At the First SPAC Merger Effective Time, each
ordinary share, no par value, of BSGA (the “BSGA Ordinary Share”) issued and outstanding immediately prior to the First SPAC
Merger Effective Time was automatically cancelled and ceased to exist in exchange for the right to receive, without interest, one Class A
ordinary shares of the Company, par value US$0.0000001 per share (the “Class A Ordinary Share”).



At the effective time of the Acquisition Merger (the
 “Acquisition Merger Effective Time”), (i) each ordinary share of Bitdeer, par value US$0.0000001 per share (the “Bitdeer
Ordinary Share”) and each preferred share of Bitdeer, par value US$0.0000001 per share, (together with Bitdeer Ordinary Share, the
 “Bitdeer Shares”) issued and outstanding immediately prior to the Acquisition Merger Effective Time (other than the Bitdeer
Shares beneficially owned by Mr. Jihan Wu, founder of Bitdeer, through Victory Courage Limited, the “Key Executive Shares”)
was automatically cancelled and ceased to exist in exchange for the right to receive, without interest, such number of Class A Ordinary
Shares that is equal to the Exchange Ratio (as defined below), (ii) each Key Executive Share issued and outstanding immediately prior
to the Acquisition Merger Effective Time was automatically cancelled and ceased to exist in exchange for the right to receive, without
interest, such number of Class V ordinary shares of the Company (“Class V Ordinary Shares”) that is equal to Exchange
Ratio (as defined below), (iii) each restricted share unit to acquire Bitdeer Shares issued pursuant to an award granted under Bitdeer’s
2021 Share Incentive Plan (“Bitdeer RSU”) outstanding immediately prior to the Acquisition Merger Effective Time, whether
vested or unvested, was assumed by the Company and converted into an award of restricted share units (each an “Assumed RSU”)
representing the rights to receive, on the same terms and conditions (including applicable vesting, settlement and expiration provisions)
as applied to each such Bitdeer RSU immediately prior to the Acquisition Merger Effective Time, Class A Ordinary Shares, except that
the number of Class A Ordinary Shares subject to such Assumed RSU equals the product of (A) the number of Bitdeer Ordinary Shares
that were subject to such Bitdeer RSU immediately prior to the Acquisition Merger Effective Time, multiplied by (B) the Exchange
Ratio (as defined below), rounded down to the nearest whole share and (iv) the convertible note issued by Bitdeer that is convertible
into the Bitdeer Ordinary Shares (the “Bitdeer Convertible Note”) outstanding immediately prior to the Acquisition Merger
Effective Time was assumed by the Company and represented the rights to receive, on the same terms and conditions as applied to such Bitdeer
Convertible Note, Class A Ordinary Shares, except that the number of Class A Ordinary Shares to be received upon conversion
of the Bitdeer Convertible Note equals the product of the number of Bitdeer Ordinary Shares issuable upon conversion of the Bitdeer Convertible
Note multiplied by the Exchange Ratio (as defined below), rounded down to the nearest whole share.



As used herein, “Exchange Ratio” means
the quotient obtained by dividing (A) 118,000,000 by (B) the Bitdeer Total Shares, and is approximately 0.00858; and “Bitdeer
Total Share” equals, as of immediately prior to the Acquisition Merger Effective Time, the sum of (x) the number of issued
and outstanding Bitdeer Shares (on an as-converted basis), (y) the aggregate number of Bitdeer Shares (on an as-converted basis)
issuable upon the settlement of all vested Bitdeer RSUs as of immediately prior to the Acquisition Merger Effective Time (including after
giving effect to the consummation of the Acquisition Merger or any acceleration of any unvested Bitdeer RSUs in connection with the consummation
of the Acquisition Merger) and (z) the aggregate number of Bitdeer Shares (on an as-converted basis) issuable upon conversion of
the Bitdeer Convertible Note.













On April 14, 2023, Class A Ordinary
Shares commenced trading on the Nasdaq Stock Market (“Nasdaq”) under the symbol “BTDR.”



Accounting for the Business Combination



The Business Combination
will be accounted for as a “reverse recapitalization” in accordance with IFRS. Under this method of accounting, BSGA will
be treated as the “acquired” company for financial reporting purposes. This determination is primarily based on the fact that
subsequent to the Business Combination, the Bitdeer’s shareholders are expected to have a majority of the voting power of the Company,
Bitdeer will comprise all of the ongoing operations of combined company, Bitdeer will comprise a majority of the governing body of combined
company, and Bitdeer’s senior management will comprise all of the senior management of the combined company. Since BSGA does not
meet the definition of a business under IFRS, the transaction is outside the scope of IFRS 3, “Business Combinations”, and
it is accounted for as an equity-settled, share-based payment transaction in accordance with IFRS 2, “Share-based Payments”.
Accordingly, for accounting purposes, the Business Combination will be treated as the equivalent of Bitdeer issuing shares for the net
assets of BSGA, accompanied by a recapitalization. The net assets of BSGA will be stated at historical costs. Any difference in the fair
value of the consideration deemed to have been issued by Bitdeer and the fair value of BSGA’s identifiable net assets represents
a listing service received by Bitdeer and is recorded through profit and loss. No goodwill or other intangible assets will be recorded.
Operations prior to the Business Combination will be those of Bitdeer.



Basis of Pro Forma Presentation



The unaudited pro forma combined
financial information included in this Exhibit has been prepared using actual redemption of BSGA Ordinary Shares into cash.



Bitdeer is providing this
information to aid you in your analysis of the financial aspects of the Business Combination. The unaudited pro forma condensed combined
financial statements described above and the assumption and estimates underlying the unaudited pro forma adjustments set forth in the
unaudited pro forma condensed combined financial statements should be read in conjunction with Bitdeer’s and BSGA’s historical
financial statements and the related notes thereto.



The pro forma adjustments
are preliminary, and the unaudited pro forma information have been presented for illustrative purposes only and are not necessarily indicative
of the financial position or results of operations that may have actually occurred had the Business Combination taken place on the dates
noted, or of Bitdeer’s future financial position or operating results. Further, the unaudited pro forma condensed combined financial
statements do not purport to project the future operating results or financial position of Bitdeer following the completion of the Business
Combination. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date
of these unaudited pro forma condensed combined financial statements and are subject to change as additional information becomes available
and analyses are performed.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
FINANCIAL INFORMATION



Note 1 — Basic of Presentation



The unaudited pro forma
condensed combined statement of financial position as of December 31, 2022 gives pro forma effect to the Business Combination
as if it had been consummated on December 31, 2022. The unaudited pro forma condensed combined statements of operations for the year
ended December 31, 2022 give pro forma effect to the Business Combination as if it had been consummated on January 1, 2022,
the beginning of the earliest period presented in the unaudited pro forma condensed combined statements of operations.



The unaudited pro forma
condensed combined statement of financial position as of December 31, 2022 has been prepared using Bitdeer’s consolidated statement
of financial position as of December 31, 2022 and BSGA’s balance sheet as of December 31, 2022.



The unaudited pro forma condensed
combined statement of operations for the year ended December 31, 2022 has been prepared using Bitdeer’s consolidated statement
of operations and loss for the year ended December 31, 2022 and BSGA’s statement of operations for the year ended December 31,
2022.



The historical financial
statements of Bitdeer have been prepared in accordance with the International Financial Reporting Standards (“IFRS”) and in
its presentation and reporting currency of the United States dollars (US$). The historical financial statements of BSGA have been prepared
in accordance with the Generally Accepted Accounting Principles in the United States (“U.S. GAAP”) in its presentation and
reporting currency of United States dollars (US$).



Management has made significant
estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial
information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information
presented.



The unaudited pro forma adjustments
represent management’s estimates based on information available as of the date of these unaudited pro forma condensed combined financial
statements and based on certain assumptions and methodologies that management believes are reasonable under the circumstances. The unaudited
condensed pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes
available and analyses are performed. Therefore, the actual adjustments may materially differ from the pro forma adjustments. Management
considers this basis of presentation to be reasonable under the circumstances.



The unaudited pro forma
condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position
would have been had the Business Combination taken place on the dates indicated, nor are they indicative of the future consolidated results
of operations or financial position of the post-combination company. They should be read in conjunction with the historical financial
statements and notes thereto of Bitdeer and BSGA.



Note 2 — Adjustments to Unaudited Pro Forma
Condensed Combined Financial Information



The unaudited pro forma
condensed combined financial information has been prepared to illustrate the effect of the Business Combination and has been prepared
for informational purposes only.



The following unaudited pro forma
condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the
final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” Release
No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the
transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction
effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Bitdeer has elected
not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the following unaudited
pro forma condensed combined financial statements.













Bitdeer and BSGA have not
had any historical relationship prior to the Business Combination other than item as described in (A) below. Accordingly, such transaction
accounting adjustments were required to eliminate activities between the companies.



Transaction Accounting Adjustments to Unaudited
Pro Forma Condensed Combined Statement of Financial Position

adjustments included in the unaudited pro forma condensed combined statement of financial position as of December 31, 2022 are

Transaction Accounting Adjustments to Unaudited Pro Forma Condensed

The transaction accounting adjustments included
in the unaudited pro forma condensed combined statements of operations for the year ended December 31, 2022 are as follows:



| | (AA) | Reflects the approximately $4.2 million of BSGA’s transaction costs incurred subsequent to December 31, 2022 as if the Business Combination had been consummated on January 1, 2022, the date the Business Combination occurred for the purposes of the pro forma combined statement of operations. This is a non-recurring item;                        
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | (BB) | Represents $37.0 million of expense recognized with income tax effect of approximately $2.5 million in accordance with IFRS 2, for the excess of the fair value of BSGA Ordinary Shares issued over the fair value of BSGA’s identifiable net assets, as described in (I), for the year ended December 31, 2022. These costs are a nonrecurring item; and
| | (CC) | Represents the elimination of interest income earned from the Trust Account for the year ended December 31, 2022.                                                                                                                                                                                                                                        



Note 3 —  Loss per Share



Represents the loss per share
(“EPS”) calculated using the historical weighted average shares outstanding, and the change in number of shares in connection
with the Business Combination, assuming the shares were outstanding at the beginning of the period presented. As the Business Combination
and related transactions are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted
average shares outstanding for basic and diluted loss per share assumes that the shares issuable relating to the Business Combination
have been outstanding for the entire period presented.



Loss per share is computed
by dividing pro forma loss for the periods by the weighted average number of ordinary shares outstanding during the periods using
the two-class method. Using the two-class method, net loss for the periods are allocated between the Class A Ordinary Shares, the
Class V Ordinary Shares and other participating securities (i.e. preference shares) based on their participating rights. Except for
voting rights, the Class A Ordinary Shares and the Class V Ordinary Shares have all the same rights and therefore the pro forma
loss per share for both classes of shares are identical. The pro forma loss per share amounts are the same for Class A Ordinary
Shares and the Class V Ordinary Shares because the holders of each class are entitled to equal per share dividends or distributions
in liquidation.
