SEC filingRevenue declined 5% YoY and margins compressed due to absence of political ad spend and DSP platform changes.
For the three months ended September 30, 2025, PubMatic reported revenue of $67.96 million, a decrease of 5% compared to $71.79 million in the same period last year. The decline was primarily attributed to the absence of incremental political advertising spend that benefited the prior year period, as well as negative short-term impacts from platform changes implemented by one of the company's large DSP buyers. Gross profit decreased 8% to $42.56 million, with gross margin slightly declining from 64% to 63% due to the revenue drop, even as cost per impression decreased 20% year-over-year. Operating loss widened to $8.42 million from $1.37 million, reflecting higher operating expenses, particularly in sales and marketing (up 9%) and technology and development (up 9%). Net loss was $6.45 million compared to $0.91 million in the prior year. Adjusted EBITDA fell to $11.15 million from $18.55 million, representing a margin decline from 25.8% to 16.4%.
The MD&A does not report segment-level revenue, but it highlights key operational metrics. As of September 30, 2025, PubMatic served approximately 1,980 publishers, up from 1,900 a year ago. Supply Path Optimization (SPO) represented over 55% of total activity in Q3 2025, underscoring its role as a growth driver. The net dollar-based retention rate dropped to 98% from 112%, indicating weaker expansion and retention among existing publishers. The company processed approximately 980 billion ad impressions daily in September 2025, demonstrating scale but with lower revenue per impression due to mix and competitive dynamics.
Management expects revenue to be affected by macroeconomic conditions for the remainder of 2025 and negatively impacted in the near term by DSP platform changes. Cost of revenue is anticipated to be higher in absolute dollars as capacity expands, but cost per impression should continue to decline. Operating expenses are expected to increase in absolute dollars, driven by headcount investments in sales, marketing, and technology, as well as legal costs related to ongoing litigation. The company maintains a strong liquidity position with $136.5 million in cash and marketable securities and a $100.0 million share repurchase authorization extended through 2026. No specific numerical guidance was provided, but the focus remains on long-term competitive advantages in omnichannel reach, infrastructure efficiency, and transparency.
As of September 30, 2025, PubMatic held $136.5 million in cash and cash equivalents, up from $100.5 million at December 31, 2024. Marketable securities were zero, compared to $40.1 million at year-end 2024. The company had no borrowings under its $110.0 million revolving credit facility, which matures October 2027. Total assets were $676.2 million, down from $739.5 million, driven by a reduction in accounts receivable ($362.6M vs $424.8M) and marketable securities. Stockholders' equity decreased to $245.1 million from $277.3 million, primarily due to share repurchases and net losses.
Total minimum lease payments under operating and finance leases were $56.2 million as of September 30, 2025, with $9.7 million due within one year. The company also has three irrevocable letters of credit totaling $5.1 million related to facility leases. Purchase obligations primarily relate to data center providers; no material changes were disclosed from the prior year-end.
During the nine months ended September 30, 2025, PubMatic repurchased 4,036,242 shares for $46.0 million. The board authorized an additional $100 million in May 2025, extending the program to December 31, 2026, with $94.4 million remaining. No dividends were declared. Capital expenditures totaled $23.5 million (including capitalized software), representing 11.6% of revenue. No debt was issued or repaid.
The company operates as a single reporting segment. For the nine months ended September 30, 2025, revenue was $202.9 million, down 1.4% year-over-year. Geographic breakdown: United States $115.1M (56.7%), EMEA $64.2M (31.6%), APAC $19.3M (9.5%), Rest of world $4.3M (2.1%). The primary segment profit measure is consolidated net loss, which was $21.1 million for the period.
Operating cash flow of $62.9M exceeded net loss of ($21.1M), reflecting strong non-cash add-backs (depreciation & amortization $34.0M, stock-based compensation $29.0M) and a large working capital inflow from accounts receivable ($62.2M). The capex intensity (PP&E $7.5M + capitalized software $16.1M = $23.5M) consumed 37% of CFO, leaving free cash flow of approximately $39.4M. Share repurchases of $47.7M exceeded FCF, funded by investing cash inflows from marketable securities sales/maturities. The large AR swing is a positive anomaly, likely due to improved collections or revenue timing. No dividends were paid.
