Material Changes Versus the Prior Comparable Period
- Q3 revenue declined 1%, while nine-month revenue was essentially flat year over year.
- Gross margin declined eight percentage points in both comparison periods, primarily due to infrastructure capacity expansion and engineering investments. Cost of revenue increased 21% in Q3 and 28% for the nine months.
- Operating expenses increased 15% in Q3 and 26% for the nine months. Nine-month technology and development expense increased 33%, and sales and marketing expense increased 23%.
- Nine-month operating results included a $5.7 million bad-debt expense related to a DSP buyer that filed for Chapter 11 bankruptcy. The related uncollectible receivables totaled $14.5 million, of which $8.8 million was subject to publisher chargeback or expected recovery.
- Net dollar-based retention declined to 97% for the trailing twelve months ended September 30, 2023, from 120% in the prior-year period, primarily due to a decline in the run rate of one publisher.
- Interest income increased to $2.2 million in Q3 and $6.3 million for the nine months, compared with $0.6 million and $1.0 million, respectively, due to higher interest rates.
- The prior-year period included a $6.4 million impairment charge on an equity investment; no comparable impairment was recorded in 2023.

Outlook, Commentary, Risks, and Unusual Items
Management expects cost of revenue, technology and development expense, sales and marketing expense, and general and administrative expense to be higher in 2023 than in 2022, reflecting continued infrastructure expansion, technology investment, headcount growth, and marketing programs. The filing does not provide a specific revenue, margin, or earnings forecast.
Management stated that existing cash, marketable securities, expected operating cash flow, and available credit capacity should be sufficient to meet working capital requirements for at least the next 12 months, while cautioning that weaker operating performance could adversely affect liquidity.
- Advertising demand remains sensitive to macroeconomic conditions, inflation, interest rates, foreign exchange movements, geopolitical conflicts, banking-system instability, and seasonal spending patterns.
- The business depends on retaining premium publishers and large DSP buyers, including concentrated relationships that may change without minimum spending or supply commitments.
- Digital advertising pricing and take rates face competitive pressure, including from larger platforms and private marketplace offerings.
- Privacy regulation, consent requirements, cookie and mobile-identifier restrictions, ad blocking, and evolving U.S. and international data-transfer rules could reduce inventory, demand, data availability, or increase compliance costs.
- Platform outages, cybersecurity incidents, fraud, malware, software defects, and reliance on third-party data centers could impair operations and customer relationships.
- Foreign exchange exposure remains material; management estimated that a hypothetical 10% change in the U.S. dollar exchange rate against the Indian rupee or British pound could change nine-month operating loss by approximately $1.4 million or $1.3 million, respectively.
- Lease liabilities totaled $23.1 million in present value, and the company reported $4.5 million of long-term income tax liabilities related to uncertain tax positions, with timing of future cash outflows unclear.
- The company reported no material pending legal proceedings and no material changes to non-cancelable purchase obligations disclosed in its 2022 Form 10-K.
- Disclosure controls and procedures and internal control over financial reporting were effective at a reasonable assurance level as of September 30, 2023.
