Topic: DSP逆风时间线及AI增长驱动
Key points:
- DSP逆风将在Q3中旬完全消退（影响从Q3初开始，到中旬完全抵消）
- 管理层认为AI是继RTV和移动后的第三次行业变革，规模更大；AI将扩展TAM，重塑价值链
- CTV、移动应用、Commerce Media增长强劲；Q1新兴收入（含AI）同比增超80%
Mgmt stance: 看涨，因AI带来巨大增长机会，且多元化驱动因素明确

Topic: Q2指引中的DSP剔除增长、宏观保守性
Key points:
- Q2报告的营收指引中点约低单位数（含DSP），剔除DSP后中点约低单位数、上边界高单位数
- Q1剔除DSP的实际增长为13%（非18%），管理层指出Q2是最后一个完整叠加DSP逆风的季度
- 预计Q3恢复报告期同比增长，下半年加速至双位数
- AI相关收入（含代理式活动）是下半年双位数增长的重要支撑
Mgmt stance: 谨慎乐观，宏观存在噪音但基本面前景良好，Q2势头稳定

Topic: 中端DSP增长与宏观环境假设
Key points:
- 过去一年新增超50家DSP，中端DSP（尤其是上中端市场）增速快于大企业广告主
- AI将进一步降低中端DSP的客户接入和服务成本，推动其份额提升
- 4月广告支出健康，多个垂直行业同比双位数增长；目前未出现明显宏观放缓
- 管理层对下半年宏观持谨慎乐观态度，政治广告未给出具体数值（仅提及Q3/Q4时未量化）
Mgmt stance: 谨慎乐观，依赖业绩广告透明度及多元化垂直组合应对不确定性

Topic: AI (AgenticOS) 对市场结构与业务长期形态的影响
Key points:
- 应用 AI 跨越全价值链（端到端），而非仅限于 SSP 或 DSP 孤岛；端到端数据可用性可带来更好广告效果与效率。
- Activate 直购结合 AgenticOS（已披露超 30 个活跃活动），客户实现工作媒体效率提升：CPM 改善 30%-40%，可购买媒体量增加 40%，且营收增长。
- AI 推动用户界面过时，客户使用 AgenticOS 可实现 80%-90% 的广告活动设置时间节省。
Mgmt stance: 非常乐观。认为 AI 是千载难逢的机遇，能拉平围墙花园与开放互联网的差距，公司凭借自建基础设施与 AI 先发优势可同时实现营收增长与利润率扩张（利用固定成本基础）。

Topic: Google 反垄断审判影响；AgenticOS 客户反馈与定价更新
Key points:
- Google 反垄断：预计判决（结构性/行为性救济）随时可能出台；公司估计 Google 占 60% 市场份额，其每 1% 份额流失可为 PUBM 带来 5000 万-7500 万美元营收，利润率约 8%；目前 PUBM 份额 4%，存在翻倍机会。
- AgenticOS 反馈：正面惊喜在于 AI 不仅能提升效率（减少手动时间），还能显著提升广告效果（无人类偏见，优化更快）；独立代理商采用速度比控股公司更快。
- 定价模式：Activate 产品保持收入分成模式；AI 工具部分场景探索订阅模式；AI 买家通过 Activate 购买时，全部支出留在公司生态内，带来增量收入分成收益。
Mgmt stance: 非常乐观（反垄断为巨大机遇，叠加 AgenticOS 推动下半年双位数增长与利润率扩张）。
