Highlights for the Three Months Ended March 31, 2023

¹ Adjusted net income (loss) is a non-IFRS financial measure. See the “Use of Non-IFRS Financial Measures” section of this prospectus supplement for the definition of such non-IFRS measure.

² Key Customers refers to the Company’s brand customers who contributed revenue of more than $50,000 in the trailing 12 months ended on the measurement date.

Financial Results for the Three Months Ended March 31, 2023

Revenue

Total revenue was $12.1 million for the three months ended March 31, 2023, up by 9.7% quarter over quarter from $11.1 million at the end of 2022, and up by 0.9% from $12.0 million in the same period of 2022.

Gross Profit

Gross profit was $9.6 million for the three months ended March 31, 2023, representing a 78.8% gross margin, compared to $10.4 million, or an 86.2% gross margin, in the same period of 2022. This was due to a change in our cost of goods sold, which was driven by the growth in mobile beauty app subscriptions which resulted in higher platform fees paid to third-party digital distribution platforms (Apple and Google).

Total Operating Expenses

Total operating expenses decreased by 0.9% to $11.1 million for the three months ended March 31, 2023 from $11.2 million in the same period of 2022, demonstrating management’s successful efforts to control costs and enhance productivity.

Net Income

Net income was $0.7 million for the three months ended March 31, 2023, compared to a net loss of $0.5 million during the same period of 2022, mainly driven by $2.2 million interest income during the quarter.

Adjusted Net Income (Non-IFRS)

Adjusted net income was $1.4 million for the three months ended March 31, 2023, compared to adjusted net income of $1.2 million in the same period of 2022.

Liquidity

As of March 31, 2023, the Company held $95.1 million in cash and cash equivalents (or $196.1 million when including 6-month and longer time deposits of $101.0 million, which are classified as current financial assets at amortized cost under IFRS), compared to $162.6 million as of December 31, 2022 (or $192.6 million when including time deposits).

Recent Developments

On March 20, 2023, the Company filed a Form 6-K with the SEC informing its investors that it does not maintain any accounts or hold any deposits or securities at Silicon Valley Bank (“SVB”) or Credit Suisse Group AG (“Credit Suisse”), and it does not otherwise have any material banking relationship, or a direct or indirect affiliation, with SVB, any other U.S. regional banks, or Credit Suisse.

Business Outlook

Looking further into 2023, the strong growth momentum in online AR/AI cloud solutions and subscriptions in the first quarter of 2023 aligns with management’s expectations and is a result of our strategies to prioritize AI innovations and online subscription solutions.

In addition, the robust growth trajectory of our mobile beauty apps reflects consumers’ subscription preference to unlock premium features and to add-on the new AIGC features. We will continue to invest in more premium value-add AI features in our family of mobile beauty apps to fuel the future growth of our online services.

As brands and retailers continue to undergo a digital transformation, AI and AR technology is a crucial component for bringing immersive and personalized shopping experiences across omni-channels. To conclude, with the above strong signs of growth in each respective area and a healthy market demand, the Company is confident to deliver strong growth in 2023.

Forward-Looking Statements

This prospectus supplement contains forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, that are based on beliefs and assumptions and on information currently available to Perfect. In some cases, you can identify forward-looking statements by the following words: “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing,” “target,” “seek” or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Any statements that refer to expectations, projections or other characterizations of future events or circumstances, including strategies or plans, are also forward-looking statements. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by these forward-looking statements. These statements are based on Perfect’s reasonable expectations and beliefs concerning future events and involve risks and uncertainties that may cause actual results to differ materially from current expectations. These factors are difficult to predict accurately and may be beyond Perfect’s control. Forward-looking statements in this prospectus supplement or elsewhere speak only as of the date made. New uncertainties and risks arise from time to time, and it is impossible for Perfect to predict these events or how they may affect Perfect. In addition, risks and uncertainties are described in Perfect’s filings with the Securities and Exchange Commission. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Perfect cannot assure you that the forward-looking statements in this prospectus supplement will prove to be accurate. There may be additional risks that Perfect presently does not know or that Perfect currently does not believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by Perfect, its directors, officers or employees or any other person that Perfect will achieve its objectives and plans in any specified time frame, or at all. Except as required by applicable law, Perfect does not have any duty to, and does not intend to, update or revise the forward-looking statements in this prospectus supplement or elsewhere after the date of this prospectus supplement. You should, therefore, not rely on these forward-looking statements as representing the views of Perfect as of any date subsequent to the date of this prospectus supplement.

Use of Non-IFRS Financial Measures

This prospectus supplement and accompanying tables contain certain non-IFRS financial measures, including adjusted net income, as supplemental metrics in reviewing and assessing Perfect’s operating performance and formulating its business plan. Perfect defined these non-IFRS financial measures as follows:

Adjusted net income (loss) is defined as net income (loss) excluding one-off transaction costs³, non-cash equity-based compensation, non-cash evaluation (gain)/loss of preferred shares, and foreign exchange (gain)/loss. For a reconciliation of adjusted net income (loss) to net income (loss), see the reconciliation table included elsewhere in this press release.

Non-IFRS financial measures are not defined under IFRS and are not presented in accordance with IFRS. Non-IFRS financial measures have limitations as analytical tools, which possibly do not reflect all items of expense that affect our operations. Share-based compensation expenses have been and may continue to be incurred in our business and are not reflected in the presentation of the non-IFRS financial measures. In addition, the non-IFRS financial measures Perfect uses may differ from the non-IFRS measures used by other companies, including peer companies, and therefore their comparability may be limited. The presentation of these non-IFRS financial measures is not intended to be considered in isolation from or as a substitute for the financial information prepared and presented in accordance with IFRS. The items excluded from our adjusted net income are not driven by core results of operations and render comparison of IFRS financial measures with prior periods less meaningful. We believe adjusted net income provides useful information to investors and others in understanding and evaluating our results of operations, as well as providing a useful measure for period-to-period comparisons of our business performance. Moreover, such non-IFRS measures are used by our management internally to make operating decisions, including those related to operating expenses, evaluate performance, and perform strategic planning and annual budgeting.

³ The one-off transaction cost in the first quarter of 2022 and 2023 included professional services expenditures that the Company incurred in connection with the de-SPAC transaction.
