Further, the unaudited pro forma combined financial information also may not be useful in predicting the future financial condition and results of operations of New Nautilus. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date of these unaudited pro forma combined financial statements and are subject to change as additional information becomes available and analyses are performed.

Note 1—Description of the Business Combination

On June 9, 2021, New Nautilus consummated the previously announced Business Combination pursuant to Business Combination Agreement dated February 7, 2021 between ARYA and Nautilus, under the terms of which, ARYA acquired Nautilus, upon domestication of ARYA, through which a wholly-owned subsidiary of ARYA merged with and into Nautilus, with Nautilus becoming a wholly-owned subsidiary of ARYA, referred to herein as New Nautilus, which became a publicly-listed entity. As a result of the Business Combination, New Nautilus owns, directly or indirectly, all of the issued and outstanding equity interests of Nautilus and the Nautilus equity holders hold a portion of the New Nautilus Common Stock.

As a result of the Business Combination Agreement, Nautilus equity holders received an aggregate number of shares of New Nautilus Common Stock equal to (i) $900.0 million plus $24.3 million, which reflects the aggregate exercise price of all stock options (whether vested or unvested) of Nautilus at the consummation of the Business Combination, divided by (ii) $10.00 giving effect to the Exchange Ratio of approximately 3.6281 based on the terms of the Business Combination Agreement. At the Closing, (i) an aggregate of 18,721,137 shares of Class A and Class B ordinary shares of ARYA were exchanged for an equivalent number of Common Stock pursuant to the Domestication, (ii) an aggregate of 85,324,118 shares of Common Stock were issued in exchange for the shares of Nautilus outstanding as of immediately prior to the Effective Time and (iii) an aggregate of 20,000,000 shares of Common stock were issued to the PIPE Investors in the PIPE Financing with total gross proceeds of $200 million. Moreover, at the Closing, all options to purchase shares of Nautilus were exchanged for comparable options to purchase shares of Common Stock based on an implied Nautilus equity value of $900 million. Immediately after giving effect to the transactions, there were 124,045,255 shares of Common Stock outstanding and 7,106,767 shares of Common Stock subject to outstanding options under the 2017 Plan.

The following summarizes the number of New Nautilus Common Stock outstanding following the consummation of the Business Combination and the PIPE Financing, based on the estimated aggregate exercise price of all options (whether vested or unvested) of Nautilus at the consummation of the Business Combination excluding the potential dilutive effect of the exercise or vesting of warrants and stock options:

Shareholder	Shares	%
Former ARYA Class A Shareholders	14,983,637	12.1	%
Former ARYA Class B Sponsor Shares	3,737,500	3.0	%
Perceptive PIPE Investor	5,500,000	4.4	%
Other PIPE Investors	14,500,000	11.7	%
Former Nautilus shareholders	85,324,118	68.8	%
Total	124,045,255	100.0	%

Note 2—Basis of Presentation

The accompanying unaudited pro forma condensed combined financial information gives effect to the Business Combination and related PIPE Financing. Pro forma transaction accounting adjustments are included only to the extent they are adjustments that reflect the accounting for the Business Combination and related PIPE Financing in accordance with U.S. GAAP.

This Business Combination was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, ARYA is expected to be treated as the "acquired" company for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of New Nautilus will represent a continuation of the financial statements of Nautilus with the Business Combination treated as the equivalent of Nautilus issuing stock for the net assets of ARYA, accompanied by a recapitalization. The net assets of ARYA will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination will be those of Nautilus in future reports of the New Nautilus. The determination is primarily based on the evaluation of the following facts and circumstances taking into consideration both the no redemption and maximum redemption scenario:

•The pre-combination equity holders of Nautilus will hold the majority of voting rights in New Nautilus;

7

•The pre-combination equity holders of Nautilus will have the right to appoint the majority of the directors on the New Nautilus Board;

•Senior management of Nautilus will comprise the senior management of New Nautilus; and

•Operations of Nautilus will comprise the ongoing operations of New Nautilus.

Under the reverse recapitalization model, the Business Combination will be treated as Nautilus issuing equity for the net assets of ARYA, with no goodwill or intangible assets recorded.

If the actual facts are different than these assumptions, then the amounts and shares outstanding in the unaudited pro forma condensed combined financial information will be different.

New Nautilus assumed outstanding and unexercised equity awards for employees and converted them into New Nautilus equity awards upon the consummation of the Business Combination. Accordingly, no effect has been given to the unaudited pro forma condensed combined financial information for the new awards.

The unaudited pro forma condensed combined financial information does not reflect the income tax effects of the pro forma adjustments as any change in the deferred tax balance would be offset by an increase in the valuation allowance given that Nautilus incurred significant losses during the historical periods presented.

As the Business Combination is being reflected as if it had occurred as of January 1, 2020, the calculation of weighted average shares outstanding for basic and diluted net loss per share assumes the shares issued in connection with the Business Combination have been outstanding for the entire periods presented.
