Description of the Transactions

On April 6, 2021, MCAD entered into the Merger Agreement with Merger Sub and BTX. Pursuant to the Merger Agreement, at the closing of the transactions contemplated thereby, Merger Sub merged with and into BTX with BTX surviving the Merger as a wholly owned subsidiary of MCAD. In addition, in connection with the consummation of the Business Combination, MCAD was renamed “Better Therapeutics, Inc.”

Under the Merger Agreement, MCAD acquired all of the outstanding BTX shares for approximately $151.7 million in aggregate consideration, comprising (i) 15,000,000 shares of MCAD’s Common Stock, based on a price of $10.00 per share, and (ii) 174,729 shares with respect to the expected Net Debt Adjustment for BTX debt based on a price of $10.00 per share. The number of shares in the Merger Consideration issuable were subject to adjustment at a rate of one share of MCAD Common Stock for each $10.00 increment of Net Debt (as defined in the Merger Agreement). The common stock price of $10.00 per share is used here for illustrative purposes and won’t have an impact on the accounting for the transactions as the transactions will be accounted for as reverse capitalizations.

In connection with the Merger, MCAD entered into subscription agreements (the “Subscription Agreement”) dated as of April 6, 2020, with certain institutional and accredited investors, pursuant to which, among other things, MCAD agreed to issue and sell, in a private placement immediately prior to the closing of the Business Combination, an aggregate of 5,000,000 shares of Common Stock for $10.00 per share (the “PIPE Shares”). The Subscription Agreement provides for certain registration rights to the purchasers of the PIPE Shares.

The BTX stock options were assumed by MCAD and automatically converted into an option to purchase such number of shares of Common Stock equal to the product of (x) the number of shares of BTX stock subject to the stock option, and (y) the Exchange Ratio as described below, with the exercise price per share of the assumed option equal to the quotient by dividing the exercise price per share by the Exchange Ratio. The outstanding BTX restricted stock awards were converted into such number of shares of Common Stock equal to the product of (x) the number of shares of BTX restricted stock, and (y) the Exchange Ratio. Each assumed restricted stock award will continue to be subject to the terms and conditions set forth in the applicable restricted stock agreement.

Accounting for the Merger

The Merger will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, MCAD, who is the legal acquirer, will be treated as the “acquired” company for financial reporting purposes and BTX will be treated as the accounting acquirer. This determination was primarily based on BTX having a majority of the voting power of the post-combination company, BTX’s senior management comprising substantially all of the senior management of the post- combination company, the relative size of BTX compared to MCAD, and BTX’s operations comprising the ongoing operations of the post-combination company. Accordingly, for accounting purposes, the Merger will be treated as the equivalent of a capital transaction in which BTX is issuing stock for the net assets of MCAD. The net assets of MCAD will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Merger will be those of BTX.

Basis of Pro Forma Presentation

The historical financial information has been adjusted to give pro forma effect to include adjustments which reflect the accounting required by GAAP. The adjustments presented on the unaudited pro forma combined financial statements have been identified and presented to provide relevant information necessary for an accurate understanding of the transaction, PIPE financing, and other adjustments for the post- combination company upon consummation of the Business Combination.

The unaudited pro forma condensed combined financial information is for illustrative purposes only. The financial results may have been different had the companies always been combined. You should not rely on the unaudited pro forma combined financial information as being indicative of the historical financial position and results that would have been achieved had the companies always been combined or the future financial position and results that the post-combination company will experience. BTX and MCAD have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The MCAD common stock comprises a combination of redeemable and non-redeemable shares. Historical net loss per share has been presented on a two-class basis to present the net loss per share for each of the redeemable and non-redeemable shares. Subsequent to the closing of the Business Combination, BTX will have no redeemable shares outstanding and therefore net loss per share has only been presented for the non-redeemable class of common stock for the pro forma net loss per share.

Included in the shares outstanding and weighted-average shares outstanding as presented in the pro forma combined financial statements are 15,174,729 shares of MCAD Common Stock that were issued to BTX stockholders. Refer to the Net Loss Per Share table below.

As a result of the Business Combination and immediately following the closing of the Business Combination, current stockholders of BTX own approximately 64% of the outstanding Combined Entity common stock, the PIPE Investors own approximately 21% of the outstanding Combined Entity common stock, MCAD’s Sponsor, officer, directors and other holders of founder shares own approximately 8% of the Combined Entity common stock and the former stockholders of MCAD own approximately 7% of the outstanding Combined Entity common stock as of September 30, 2021 (in each case, not giving effect to any shares issuable to them upon exercise of rights or options). As a result, current stockholders of BTX, as a group, will collectively own more shares of Combined Entity common stock than any single stockholder following consummation of the Business Combination with no current stockholder of MCAD owning more than 10% of the issued and outstanding capital stock of the Combined Entity.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1. Basis of Presentation

The pro forma adjustments have been prepared as if the Business Combination had been consummated on September 30, 2021 in the case of the unaudited pro forma condensed combined balance sheet and on January 1, 2020, the beginning of the earliest period presented in the unaudited pro forma condensed combined statement of operations.

The unaudited pro forma condensed combined financial information has been prepared assuming the following methods of accounting in accordance with U.S. GAAP.

Notwithstanding the legal form of the Business Combination pursuant to the Merger Agreement, the Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, MCAD will be treated as the acquired company and BTX will be treated as the acquirer for financial statement reporting purposes. BTX has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances:

• BTX’s existing stockholders have the greatest ownership interest in the Combined Entity with BTX Equityholders controlling 64% of the outstanding common stock of the Combined Entity.

• BTX’s directors represent substantially all of the Combined Entity’ board of directors.

• BTX’s senior management is the senior management of the Combined Entity.

• BTX will continue its operations in substantially the same form as the post-combination company.

Accordingly, for accounting purposes, the financial statements of the Combined Entity will represent a continuation of the financial statements of BTX with the acquisition being treated as the equivalent of the BTX issuing stock for the net assets of MCAD, accompanied by a recapitalization. The net assets of MCAD will be stated at historical cost, with no goodwill or other intangible assets recorded.

One-time direct and incremental transaction costs incurred prior to, or concurrent with, the consummation are reflected in the unaudited pro forma condensed combined balance sheet as a direct reduction to the Combined Entity’ additional paid-in capital and cash settled. As a result of the Business Combination being accounted for as a reverse capitalization, acquisition-related transaction costs are accounted for as equity issuance costs and the unaudited pro forma condensed balance sheet reflects these costs as a reduction of cash with a corresponding decrease to additional paid in capital.

The unaudited pro forma condensed combined financial information does not reflect the income tax effects of the pro forma adjustments. the Combined Entity’ management believes this unaudited pro forma condensed combined financial information to not be meaningful given the Combined Entity incurred significant losses during the historical periods presented.

The Combined Entity’s management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information. The unaudited pro forma condensed combined statements of operations are not necessarily indicative of what the actual results of operations would have been had the Business Combination taken place on the date indicated, nor are they indicative of the future consolidated results of operations of the Combined Entity. They should be read in conjunction with the historical audited financial statements and notes thereto of BTX and MCAD.

Based on its initial analysis, the Combined Entity’ management did not identify any differences in accounting policies that would have a material impact on the unaudited pro forma condensed combined financial information. As a result, the unaudited pro forma condensed combined financial information does not assume any differences in accounting policies. The Combined Entity’ management is performing a comprehensive review of the two entities’ accounting policies.

As a result of the review, the Combined Entity’ management may identify differences between the accounting policies of the two entities which, when conformed, could have a material impact on the financial statements of the Combined Entity.

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 the other transactions contemplated by the Merger Agreement and has been prepared for informational purposes only. The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial information to give pro forma effect to transaction adjustments and to provide relevant information necessary for an accurate understanding of the transaction, PIPE financing, and other adjustments for the post-combination company upon consummation of the Business Combination. MCAD and BTX have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

(K) Represents pro forma adjustments to eliminate the MCAD historical Retained Earnings (Accumulated Deficit) balance.

Adjustments to Unaudited Pro Forma Condensed Combined Statements of Operation

The pro forma adjustments included in the unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2021 and year ended December 31, 2020 are as follows:

(AA) Represents the expense incurred for the acceleration of CEO performance awards upon the close of the Business Combination.

(BB) Represents the reversal of the resulting change in fair value of the SAFEs for the nine months ended September 30, 2021 and year ended December 31, 2020.

3. Net loss per share

Represents the net loss per share calculated using the historical weighted average shares outstanding, and the issuance of additional shares in connection with the Business Combination, assuming the shares were outstanding since January 1, 2020. As the Business Combination is being reflected as if it had occurred at the beginning of the periods presented, the calculation of weighted average shares outstanding for basic and diluted net loss per share assumes that the shares issuable relating to the Business Combination have been outstanding for the entire periods presented. The calculation is adjusted to eliminate the actual MCAD shares redeemed for the entire periods.

The unaudited pro forma condensed combined financial information has been prepared assuming two alternative levels of redemption for the nine months ended September 30, 2021 and year ended December 31, 2020:
