RISK FACTORS SUMMARY

Our business is subject to a number of risks and uncertainties, including those risks discussed at-length in the section below titled "Risk Factors." These risks include, among others, the following:

Risks Related to our Business and Industry

•Unfavorable conditions, including, but not limited to, inflationary pressure or tariffs and other trade protection measures, in the global economy or the industries we serve could limit our ability to grow our business and negatively affect our operating results.

•Our quarterly operating results have fluctuated and may continue to vary from period to period, which could result in our failure to meet expectations with respect to operating results and cause the trading price of our stock to decline.

•We may not be able to grow or sustain our revenue or billings in the future.

•We are dependent upon the Cardlytics platform.

•If we fail to identify and respond effectively to rapidly changing technology and industry needs, our solutions may become less competitive or obsolete.

•We are substantially dependent on Chase, Wells Fargo and a limited number of other FI partners.

•The market in which we participate is competitive, and we may not be able to compete successfully with our current or future competitors.

Risks Related to our Outstanding Convertible Senior Notes

•Servicing our debt may require a significant amount of cash. We may not have sufficient cash flow from our business to pay our indebtedness, and we may not have the ability to raise the funds necessary to settle for cash conversions of the 2024 Convertible Senior Notes or to repurchase the 2024 Convertible Senior Notes for cash upon a fundamental change, which could adversely affect our business and results of operations.

Risks Related to Regulatory and Intellectual Property Matters

•We and our FI partners are subject to stringent and changing privacy and data security laws, rules, contractual obligations, self-regulatory schemes, government regulation, policies and other obligations related to data privacy and security. The actual or perceived failure by us, our customers, our partners, or other third parties whom we rely upon to comply with such obligations could lead to regulatory investigations or actions, litigation, disruptions of our business operations, loss of customers or sales, harm our reputation, result in significant expense, loss of revenue or profits, subject us to significant fines and liability or otherwise adversely affect our business.

•Failure to protect our proprietary technology and intellectual property rights could substantially harm our business, financial condition and operating results.

Risks Related to Ownership of our Common Stock

•The market price of our common stock has been, and is likely to continue to be, volatile.

•Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.
