      Case 3:25-cv-07067-JSC          Document 53          Filed 09/04/26    Page 2 of 37


 1          Lead Plaintiff Sidney Hsu (“Plaintiff”) alleges the following based upon the investigation of

 2 Plaintiff’s counsel, which included, among other things: (1) a review of United States Securities and

 3 Exchange Commission (“SEC”) filings by PubMatic, Inc. (“PubMatic” or the “Company”); (2) a

 4 review of securities analysts’ reports and advisories about the Company; (3) analysis of press

 5 releases, media reports, and other public statements issued by, or about, the Company; (4) interviews

 6 of former Company employees and other individuals with knowledge of the allegations herein; and

 7 (5) analysis of other information regarding the Company.            Plaintiff believes that substantial

 8 additional evidentiary support will exist for the allegations set forth herein after a reasonable

 9 opportunity for discovery.
10                                     NATURE OF THE ACTION
11
            1.      This is a securities class action on behalf of all persons and entities who purchased
12
     the Company’s common stock between February 27, 2025 and August 11, 2025, inclusive (“Class
13
     Period”), seeking to pursue remedies under the Securities Exchange Act of 1934 (“Exchange Act”)
14
     and SEC Rule 10b-5 promulgated thereunder.
15
            2.      PubMatic is a technology company that enables real time programmatic advertising
16
     transactions for advertisers, agencies, and demand side platforms (“DSPs”). Programmatic
17
     advertising purportedly enables buyers to purchase ad impressions on publisher supplied inventory
18
     within milliseconds in a sophisticated, technology-driven marketplace. The Company primarily
19
     generates its revenue from the use of its platform for the purchase and sale of digital advertising
20
     inventory.
21
            3.      On August 11, 2025, PubMatic released its second quarter 2025 financial report. In
22
     its report, PubMatic’s Chief Financial Officer (“CFO”), Steven Pantelick (“Pantelick”), revealed
23
     that the Company’s outlook reflected “a reduction in ad spend from one of [its] top DSP partners.”
24
     The Company’s Chief Executive Officer (“CEO”), Rajeev Goel (“Goel”), further revealed that a
25
     “top DSP buyer” had “shifted a significant number of clients to a new platform that evaluates
26
     inventory differently” causing significant headwinds. In response to the inventory valuation change,
27
     CEO Goel stated further that the Company would “need to do a better job . . . to prioritize across all
28

                                                       1


     Case 3:25-cv-07067-JSC           Document 53         Filed 09/04/26    Page 3 of 37


 1 the hundreds of billions of daily ad impressions that we have, which subset of those impressions

 2 that we send to this DSP.”

 3          4.      On this news, PubMatic’s stock price fell $2.23, or 21.1%, to close at $8.34 per share

 4 on August 12, 2025, on unusually heavy trading volume.

 5          5.      As demonstrated herein, Defendants had long known about the Company’s DSP

 6 problems before the Company’s August 11, 2025 press release. Indeed, the Company’s DSP

 7 problems were discussed in internal global meetings and weekly product management meetings that

 8 were attended by CEO Goel. For example, in 2024, PubMatic saw a big impact on monetization

 9 because of the Company’s problems with DSPs, and it was evident at that time that PubMatic was
10 not growing as fast as it had in previous years. Additionally, in 2024, there were huge projects

11 around the reprioritization of traffic to The Trade Desk that made it clear that PubMatic was

12 experiencing significant risks because of the Company’s problems with DSPs. In fact, Company

13 employees frequently expressed concerns during these meetings regarding these issues and

14 conveyed that the Company’s publishing demand was decreasing and that PubMatic faced serious

15 challenges related to revenue as a result.

16          6.      Moreover, as indicated by a former company employee, internal Company
17 documents further demonstrate that Defendants were aware of, and had access to, information

18 showing the adverse effects that the Company’s problems with DSPs were having upon PubMatic’s

19 financial results. For instance, PubMatic’s minutes for the Company’s global meetings and weekly

20 product management meetings reflect discussions related to PubMatic’s problems with DSPs in

21 general and with The Trade Desk in particular. Additionally, internal revenue reports demonstrate

22 a decrease in the Company’s revenue from DSPs, which Defendants tracked daily.

23          7.      Thus, throughout the Class Period, Defendants made materially false and misleading
24 statements and half-truths, as well as failed to disclose material adverse facts about the Company’s

25 business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (1) that

26 a top DSP buyer was shifting a significant number of clients to a new platform that evaluated

27 inventory differently; (2) that, as a result, PubMatic was seeing a reduction in ad spend and revenue

28 from this top DSP buyer; and (3) that, as a result of the foregoing, Defendants’ positive statements

                              SECOND AMENDED CLASS ACTION COMPLAINT
                                                      2


     Case 3:25-cv-07067-JSC           Document 53          Filed 09/04/26    Page 4 of 37


 1 about the Company’s business, operations, and prospects were materially misleading and lacked a

 2 reasonable basis.

 3          8.      As a result of Defendants’ misrepresentations and half-truths and the significant

 4 decline in the price of the Company’s common stock, Plaintiff and other Class members suffered

 5 substantial losses and damages.

 6                                    JURISDICTION AND VENUE

 7          9.      The claims asserted herein arise under, and pursuant to, Sections 10(b) and 20(a) of

 8 the Exchange Act, 15 U.S.C. §§78j(b) and 78t(a), and SEC Rule 10b-5 promulgated thereunder, 17

 9 C.F.R. §240.10b-5.
10          10.     This Court has jurisdiction over the subject matter of this action pursuant to 28 U.S.C.
11 §1331 and §27 of the Exchange Act.

12          11.     Venue is proper in this District pursuant to §27 of the Exchange Act and 28 U.S.C.
13 §1391(b).      Many of the acts charged herein, including the preparation and dissemination of
14 materially false and misleading information, occurred, in substantial part, in this District.

15          12.     In connection with the acts alleged in this Complaint, Defendants, directly or
16 indirectly, used the means and instrumentalities of interstate commerce, including, but not limited

17 to, the mails, interstate telephone communications, and the facilities of an electronic securities

18 exchange located in this District.

19                                                PARTIES
20          13.     As set forth in the previously filed certification that is incorporated by reference
21 herein (ECF No. 1 at 22-23), Plaintiff purchased the Company’s common stock during the Class

22 Period and has been damaged thereby.

23          14.     Defendant PubMatic is incorporated under the laws of Delaware. The Company
24 maintains a headquarters location in Redwood City, California. PubMatic’s common stock trades

25 on the NASDAQ exchange under the symbol “PUBM.”

26          15.     Defendant Rajeev K. Goel (“Goel”) was the Company’s CEO at all relevant times.
27          16.     Nonparty Steven Pantelick (“Pantelick”) was the Company’s CFO at all relevant
28 times.

                              SECOND AMENDED CLASS ACTION COMPLAINT
                                                       3


     Case 3:25-cv-07067-JSC           Document 53         Filed 09/04/26    Page 5 of 37


 1           17.    Defendants PubMatic and Goel are collectively referred to herein as “Defendants.”

 2           18.    CEO Goel is liable as a direct participant in the wrongs alleged herein. In addition,

 3 by reason of his status as a senior executive officer and/or director, CEO Goel was a controlling

 4 person within the meaning of Section 20(a) of the Exchange Act and had the power and influence

 5 to cause the Company to engage in the unlawful conduct alleged. Because of his position of control,

 6 CEO Goel was able to, and did, directly or indirectly, control the conduct of the Company’s

 7 business.

 8           19.    Because of his position within the Company, CEO Goel controlled and/or possessed

 9 the authority to control the contents of the Company’s reports, press releases, and presentations to
10 securities analysts and, through them, to the investing public. In addition, CEO Goel was provided

11 with copies of the Company’s reports and press releases alleged to be misleading herein, prior to,

12 or shortly after, their issuance and had the ability and opportunity to prevent their issuance or cause

13 them to be corrected. Thus, CEO Goel had the opportunity to commit the fraudulent acts alleged

14 herein.

15           20.    Moreover, as a senior executive officer and/or director – and as a controlling person
16 of a publicly-traded company whose common stock was, and is, governed by the federal securities

17 laws, CEO Goel had a duty to promptly disseminate accurate and truthful information with respect

18 to the Company’s financial condition and performance, growth, operations, financial statements,

19 business, products, markets, management, earnings, and present and future business prospects.

20 Additionally, CEO Goel also had a duty to correct any previously issued statements that had become

21 materially misleading or untrue so that the market price of the Company’s common stock would be

22 based upon truthful and accurate information. Defendants’ misrepresentations and half-truths

23 during the Class Period violated these specific requirements and obligations.

24           21.    CEO Goel is liable as a participant in a fraudulent scheme and course of conduct that
25 operated as a fraud and/or deceit on purchasers of the Company’s common stock by disseminating

26 materially false and misleading statements and/or concealing material adverse facts. This scheme:

27 (1) deceived the investing public regarding the Company’s business, operations and management,

28 and the intrinsic value of the Company’s common stock; (2) enabled the Company to obtain

                              SECOND AMENDED CLASS ACTION COMPLAINT
                                                      4


      Case 3:25-cv-07067-JSC          Document 53          Filed 09/04/26    Page 6 of 37


 1 additional capital at favorable prices, create a public market for its common stock, and gain access

 2 to the public equity markets; and (3) caused Plaintiff and members of the Class to purchase the

 3 Company’s common stock at artificially inflated prices.

 4                                   SUBSTANTIVE ALLEGATIONS

 5                                               Background

 6          22.     PubMatic contends that its mission is to fuel the potential of Internet content creators

 7 by providing an advertisement-funded Internet.           The Company represents that its integrated

 8 technology platform empowers content creators (which it refers to as “publishers”) across the

 9 Internet to maximize monetization of their advertising inventory. PubMatic also claims that its
10 platform provides control and transparency to buyers, which includes advertisers, agencies, agency

11 trading desks, and DSPs (which it collectively refer to as “buyers”).

12          23.     PubMatic suggests that the challenges of scale and the complexity of the digital
13 advertising ecosystem require an automated, fast, and efficient approach to purchasing ads online,

14 known as programmatic advertising. According to the Company, programmatic advertising, on an

15 automated basis, enables buyers to purchase ad impressions on publisher supplied inventory within

16 milliseconds in a sophisticated, technology-driven marketplace. PubMatic claims that with header

17 bidding (which enables a single parallel auction by a publisher with multiple interested parties

18 simultaneously), the industry has seen a significant increase in the number of ad impressions that

19 need to be processed and analyzed in real-time by each participant in the digital advertising

20 ecosystem.

21          24.     Additionally, PubMatic contends that as consumers increasingly engage with digital
22 media – and as advertisers bid on a growing array of ad formats and impressions – an immense

23 amount of data is generated. According to PubMatic, this data includes anonymized consumer

24 information about interests and intent, log files of winning and losing advertiser bids, and transaction

25 records for billing and payment reconciliation. The Company claims that technology infrastructure

26 platforms must rapidly process this data while offering a seamless digital ad experience. According

27 to PubMatic, companies must continue to innovate and find efficiencies in their data processing

28

     Case 3:25-cv-07067-JSC          Document 53         Filed 09/04/26    Page 7 of 37


 1 (including through the use of machine learning and artificial intelligence) to maintain pace with

 2 growing volumes of transactions to maintain profitability.

 3          25.     PubMatic generates revenue from the use of its platform for the purchase and sale of

 4 digital advertising inventory. The Company works primarily with publishers and app developers

 5 who allow PubMatic direct access to their ad inventory, as well as select channel partners that meet

 6 the Company’s quality and scale thresholds. PubMatic’s channel partners aggregate and provide

 7 further access to thousands of sites and apps from smaller publishers. The Company generates

 8 revenue through fees charged to its publishers, which are generally a percentage of the value of the

 9 advertising impressions that publishers monetize on the Company’s platform. PubMatic also
10 generates revenues from its other products such as OpenWrap, its header bidding solution, and

11 Connect, its solution that provides additional data and insights to buyers, which are sold separate

12 from, or in conjunction with, use of its platform. To facilitate the sale of publisher inventory,

13 PubMatic enters into written service agreements with its buyers, primarily DSPs, that allow them to

14 use the Company’s platform to buy ad inventory. As of December 31, 2024, the Company had

15 1,049 employees, of whom 319 were located in the United States, 604 in India, and 126 in other

16 offices around the world.

17                  Defendants’ False and Misleading Statements and Insider Sales
18          26.     On February 27, 2025, the Company filed its Form 10-K with the SEC for the fiscal

19 year ended December 31, 2024 (“2024 Form10-K”). Within the 2020 Form 10-K, Defendants stated

20 the following:

21          If our existing customers do not expand their usage of our platform, or if we fail
            to attract new publishers and buyers, our growth will suffer.
22
            27.     The 2024 Form 10-K also stated the following:
23
            Any disruptions in our relationships with premium publishers, buyers, or our
24          largest channel partners could adversely affect our business, results of operations,
            and financial condition. If we cannot retain or add individual publishers with
25          valuable ad impressions, or if such publishers decide not to make their valuable ad
            impressions available to us, then our buyers may be less inclined to use our
26          platform, which could adversely affect our business, results of operations, and
            financial condition.
27
            28.     Additionally, the 2024 Form 10-K further stated the following in relevant part:

 1          We expect to face challenges, risks, and difficulties frequently experienced by
            growing companies in rapidly developing industries, including those relating to:
 2
            •      changes in demand and pricing for ad impressions sold on our platform;
 3
            •      changes in our access to valuable ad impressions from publishers;
 4
            •      responding to evolving industry standards and government regulations that
 5                 impact our business, particularly in the areas of data protection and consumer
                   privacy;
 6
            •      developing, maintaining, and expanding relationships with publishers,
 7                 DSPs, agencies, advertisers, and buyers;
 8          •      seasonality in our business;
 9          •      innovating and developing new solutions that are adopted by and meet the
                   needs of publishers, DSPs, agencies, advertisers, and buyers;
10
            •      competing against companies with a larger customer base or greater financial
11                 or technical resources;
12          •      changes in the structure of the buying and selling of ad impressions;
13          •      changes in the pricing policies of publishers and competitors;
14          •      changes in demand due to changes in macroeconomic environment, including
                   as a result of an economic downturn, recession, inflation, changes in interest
15                 rates or foreign exchange rates, disruptions to supply chains, or otherwise;
16          •      further expanding our business internationally; and
17          •      recruiting, integrating, and retaining qualified and motivated employees,
                   particularly engineers.
18
            Any one or more of the factors above may result in significant fluctuations in our
19          results of operations.
20          29.    Defendants’ statements in ¶¶26-28 were false and misleading because Defendants
21 misleadingly represented that a reduction in PubMatic’s advertising spend could adversely affect

22 the Company’s business when CEO Goel knew, or was deliberately reckless in not knowing, that

23 such risks had already materialized. Indeed, contrary to Defendants’ representations that “[i]f our

24 existing customers do not expand their usage of our platform, or if we fail to attract new publishers

25 and buyers, our growth will suffer” and that “[i]f we cannot retain or add individual publishers with

26 valuable ad impressions, or if such publishers decide not to make their valuable ad impressions

27 available to us, then our buyers may be less inclined to use our platform, which could adversely

28 affect our business, results of operations, and financial condition,” CEO Goel already knew, or was

 1 deliberately reckless in not knowing, that The Trade Desk informed PubMatic in 2024 that PubMatic

 2 was being de-prioritized.

 3           30.   For example, the account of a Company Confidential Witness (“CW”) 1

 4 demonstrates that CEO Goel knew, or was deliberately reckless in not knowing, that The Trade

 5 Desk informed PubMatic in 2024 that PubMatic was being de-prioritized. CW1 worked as a

 6 Director of Global Support from August 2019 to June 2020 and as a Senior Director of Customer

 7 Enablement from June 2020 until April 2025. As Senior Director of Customer Enablement, CW1

 8 managed the Company’s platform capacity and oversaw the way PubMatic allocated space to

 9 publishers. CW1 reported to Jaan Janes (“Janes”), the Company’s former Vice President of
10 Publisher Partnerships. During CW1’s tenure, CW1 oversaw issues related to the Company’s

11 inventory. In addition to contact during Company meetings, CW1 had frequent, almost daily contact

12 with both CEO Goel and CFO Pantelick in CW1’s early years at the Company, but less so

13 subsequently.

14           31.   CW1 stated that the Company’s DSP problems were discussed in global meetings,
15 which originally occurred weekly on Mondays and subsequently occurred monthly.             CW1
16 personally attended the Company’s global meetings. CW1 stated that these global meetings were

17 also attended by CEO Goel as well as the Company’s Vice President of Product Management. CW1

18 also stated that most executives involved with PubMatic’s revenue participated in the Company’s

19 global meeting, including Chief Revenue Officer Kyle Dozeman and Executive Vice President of

20 Product Nichant Khathri (who was focused on revenue optimization and, to that end according to

21 CW1, was always working to update the back end of the Company’s systems). CW1 stated that in

22 2024, PubMatic saw a big impact on monetization because of the Company’s problems with DSPs

23 in general, and with The Trade Desk in particular, and that it “was clear” that PubMatic was not

24 growing as fast as it had in previous years. CW1 stated that CEO Goel was aware of problems with

25 revenue optimization with The Trade Desk because he participated in both the Company’s global

26 meetings and weekly product management meetings during which the participants discussed these

27 issues.

 1          32.    CW1 stated further that PubMatic’s problems with DSPs in general – and with The

 2 Trade Desk in particular – were also discussed in weekly product management meetings, which

 3 were held on Wednesdays. CW1 personally attended PubMatic’s weekly product management

 4 meetings. CEO Goel also attended the Company’s weekly product management meetings in

 5 addition to PubMatic’s global meetings.

 6          33.    During PubMatic’s weekly product management meetings, CW1 stated that the

 7 participants at the meetings spent almost all of 2024 trying to ascertain how to get revenue from

 8 DSPs to stop leaking. CW1 stated that during these meetings, the issues discussed related to the

 9 declines in the Company’s revenue were “pervasive.” For example, CW1 stated that in 2024, the
10 participants at the weekly product management meetings determined that PubMatic did not perform

11 well with video inventory in the new area of Connected TV (“CTV”), which sustained premium

12 rates.   CTV devices include Smart TVs, streaming sticks and boxes, and gaming consoles.
13 According to CW1, everything other than CTV became just a commodity and was considered

14 “cheap.” CW1 stated that the Company’s competitors like Magnite focused on developing video

15 inventory, which was “premium.” In contrast, according to CW1, PubMatic maintained its historical

16 focus on banner advertisements, which had accounted for much of the Company’s revenue in

17 previous years.

18          34.      CW1 indicated that during the Company’s weekly product management meetings
19 going back to 2024, there were huge projects around the reprioritization of traffic to The Trade Desk.

20 CW1 described that in digital advertising, typically the technology involved will favor making

21 money at any cost. However, according to CW1, to address the leakage of revenue related to The

22 Trade Desk, PubMatic optimized things in favor of The Trade Desk to the point that the Company

23 was “giving away money” to The Trade Desk. For example, CW1 stated that PubMatic’s customer

24 success team created huge projects in 2024 intended to make the Company’s inventory attractive to

25 The Trade Desk.       According to CW1, however, these projects merely consisted of cutting
26 PubMatic’s margins by 20-30% to give The Trade Desk a discounted rate to try to win back business

27 from The Trade Desk. CW1 stated that CEO Goel oversaw these strategies to try to win back

28 business from The Trade Desk. As a result, CW1 stated that it was clear to participants at the

                              SECOND AMENDED CLASS ACTION COMPLAINT
                                                      9

 1 Company’s weekly product management meetings in 2024 that PubMatic was “in a lot of danger”

 2 because of the Company’s problems with The Trade Desk.

 3          35.    Additionally, CW1 stated that during PubMatic’s weekly product management

 4 meetings, the participants discussed the fact that The Trade Desk was prioritizing competitors who

 5 were more competent in CTV, and that these market shifts drastically affected the value of the

 6 Company’s existing inventory. CW1 said, therefore, The Trade Desk was prioritizing competitors

 7 in 2024 who were more competent in CTV and was de-prioritizing PubMatic because the Company

 8 was less competent in CTV. According to CW1, as a result, banner ads became “cheap” and were

 9 increasingly considered “junky.” Thus, in 2024, CW1 stated that PubMatic’s banner inventory that
10 had previously sold for $50 each would bring in less than one dollar.

11          36.    CW1 stated further that during PubMatic’s weekly product management meetings in
12 2024, CEO Goel was furious at The Trade Desk because The Trade Desk had cut off PubMatic.

13 CW1 stated that the Company’s monetization team had asked CEO Goel to intervene to address the

14 problems that PubMatic was experiencing with The Trade Desk. CW1 stated that during the

15 Company’s weekly product management meetings that CW1 and CEO Goel attended in 2024, the

16 Company’s monetization, product, and customer success teams met to discuss how PubMatic could

17 mitigate the negative financial impacts from The Trade Desk’s decision to circumvent business

18 around PubMatic.

19          37.    CW1 also stated that during a weekly product management meeting in 2024, CEO
20 Goel was demoralized while conveying a conversation he had with The Trade Desk. Specifically,

21 CEO Goel told the meeting participants that The Trade Desk told CEO Goel that PubMatic “just

22 wasn’t big enough for The Trade Desk to care about.” CW1 stated that during a subsequent meeting,

23 CEO Goel lamented that “maybe I should have let them win at golf.”

24          38.    Additionally, CW1 stated that former Vice President of Publisher Partnerships Janes,
25 Amit Jamdade (“Jamdade”) (the former Senior Director of Customer Success), and CW1 frequently

26 voiced concerns during the weekly product management meetings regarding these issues. CW1

27 stated that Janes, in particular, was “very vocal” during these meetings in stating that the Company’s

 1 publishing demand was decreasing and that PubMatic faced serious challenges related to revenue

 2 as a result.

 3          39.     Furthermore, CW1 stated that internal Company documents demonstrate that CEO

 4 Goel was aware of, and had access to, information demonstrating the adverse effects that the

 5 Company’s problems with DSPs and The Trade Desk were having upon PubMatic’s financial

 6 results. According to CW1, PubMatic’s minutes for the global meetings reflected discussions

 7 related to PubMatic’s problems with DSPs in general and with The Trade Desk in particular. CW1

 8 also stated that minutes of the Company’s weekly product management meetings documented these

 9 problems and issues with respect to areas focused on monetization. CW1 indicated further that
10 internal revenue reports reflected a decrease in the Company’s revenue from DSPs, which

11 Defendants tracked daily. According to CW1, “the warning signs were there.” Indeed, contrary to

12 Defendants’ suggestion that issues related to “developing, maintaining, and expanding relationships

13 with publishers, DSPs, agencies, advertisers, and buyers” . . . “may result in significant fluctuations

14 in our results of operations,” CW1 stated that the Company was already experiencing DSP problems

15 in general, and with The Trade Desk in particular, in 2024 as discussed in global and weekly product

16 management meetings, which CW1 and CEO Goel personally attended.                   Thus, Defendants’
17 statements misled investors by identifying these risks as merely potential risks when, in fact, the

18 events that existed as risks had actually occurred.

19          40.     Additionally, CEO Goel’s statements at the end of the Class Period further
20 demonstrate why Defendants’ statements were false and misleading. For instance, during the

21 conference call on August 11, 2025, CEO Goel had the following exchange with an analyst:

22          Jason Helfstein - Oppenheimer & Co Inc - Analyst
23          And what made it like specific to this DSP like best to understand like how you – if
            your decision on what was valuable inventory was fine for everybody else, why was
24          it not fine for this DSP suddenly?
25          Rajeev Goel - PubMatic Inc - Chief Executive Officer, Co-Founder, Director
26          Yes. Our view is it was precipitated by a shift in clients that this DSP has from one
            platform to a different platform, and that shift corresponded with the quarter boarder.
27          So we saw that impact starting in July.

 1          41.     Importantly, CEO Goel did not claim that the shift in clients that this DSP had from

 2 one platform to a different platform occurred in July 2025. Rather, CEO Goel stated that PubMatic

 3 purportedly saw the impact of that shift in July 2025. Indeed, on June 6, 2023, The Trade Desk

 4 issued a press release entitled “The Trade Desk Launches Kokai – a New Media Buying Platform

 5 that Brings the Full Power of AI to Digital Marketing” which indicated that the shift that CEO Goel

 6 was referring to that The Trade Desk made from Solimar to Kokai occurred in 2023. CEO Goel’s

 7 statement, therefore, corroborates the account of CW1, who stated that CEO Goel attended the

 8 Company’s global meetings and weekly product management meetings in which discussions were

 9 held regarding the problems that PubMatic experienced with The Trade Desk long before PubMatic
10 purportedly observed the financial impact of that shift in July 2025.

11          42.    On March 3, 2025 – only four days after PubMatic issued its 2024 Form 10-K – CFO
12 Pantelick sold 4,000 shares of PubMatic stock at an average share price of $10.61 for proceeds of

13 $42,440.

14          43.    On April 1, 2025, CEO Goel sold 25,000 shares of PubMatic stock at an average
15 share price of $9.14 for proceeds of $228,500.

16          44.    The next day – on April 2, 2025 – CEO Goel sold 33,213 shares of PubMatic stock
17 at an average share price of $9.31 for proceeds of $309,213. On the same day, CFO Pantelick sold

18 12,061 shares of PubMatic stock at an average share price of $9.31 for proceeds of $112,288.

19          45.    The following day – April 3, 2025 – CFO Pantelick sold 18,384 shares of PubMatic
20 stock at an average share price of $8.45 for proceeds of $155,345.

21          46.    On May 5, 2025, CEO Goel sold 25,000 shares of PubMatic stock at an average share
22 price of $9.84 for proceeds of $246,000. On the same day, CFO Pantelick sold 4,000 shares of

23 PubMatic stock at an average share price of $9.83 for proceeds of $39,320.

24          47.    On May 8, 2025, the Company filed its Form 10-Q for the quarter ended March 31,
25 2025 (“1Q25 Form 10-Q”). Within the 1Q25 Form 10-Q, Defendants stated, in relevant part, the

     and misleading and failed to disclose material adverse facts about the Company’s business,

     operations, and prospects. Specifically, contrary to Defendants’ suggestion that issues related to

 1 which CW1 and CEO Goel personally attended. Accordingly, Defendants’ misrepresentations

 2 identified these risks as mere possibilities when, in fact, the risks had already materialized.

 4 because of the Company’s problems with DSPs in general, and with The Trade Desk in particular,

 5 and that it “was clear” that PubMatic was not growing as fast as it had in previous years. CW1

 6 stated that CEO Goel was aware of problems with revenue optimization with The Trade Desk

 7 because he participated in both the Company’s global meetings and weekly product management

 8 meetings during which the participants discussed these issues. CW1 stated further that PubMatic’s

 9 problems with DSPs in general – and with The Trade Desk in particular – were also discussed in

11                                    The Truth Begins to Emerge
12          67.    On August 11, 2025, after the market closed, PubMatic issued a press release

13 announcing its financial results for the quarter ended June 30, 2025. The press release stated the

14 following in relevant part:

15          While our outlook includes a reduction in ad spend from one of our top DSP
            partners, the underlying health of the business remains strong while we mitigate the
16          impact. Additionally, we are optimizing resources to focus on key priorities that
            include: diversifying DSP mix and accelerating investment on the buy-side, growing
17          CTV, scaling emerging revenue streams, and integrating AI across our tech stack and
            operations. We have a healthy balance sheet and generate positive cash flow and are
18          confident in the long-term strategy to drive durable, accelerated growth, increased
            profitability, and maximized shareholder value.
19
            68.    On the same day, PubMatic held an earnings call to discuss the quarterly results
20
     (“2Q25 Earnings Call”). During the 2Q25 Earnings Call, CEO Goel, stated the following:
21
            Today, our top legacy DSP partners contribute the majority of ad spend on our
22          platform. Historically, this strategy has delivered growth and scale. But platform
            changes on their end are often done with limited visibility and create revenue
23          headwinds for us while we take steps to mitigate them. The most recent example
            occurred just last month in July and will impact our revenue in the second half of
24          this year as we work through mitigation initiatives.

25          69.    Also during the 2Q25 Earnings Call, CFO Pantelick stated the following:

26          Looking to the second half of the year, we are confident that we’ll continue to see
            growth in these secular areas. Our end-to-end platform, SPO and recently launched
27          AI-driven solutions are helping customers scale their ad businesses while
            streamlining their operations. At the same time, beginning in July, we saw a
28          headwind emerge from another top DSP buyer, which recently made platform

 1          changes. As a result, we saw a notable drop in spend in July from this DSP, which
            has stabilized in August.
 2
            70.     Analysts were perplexed by Defendants’ explanations. Indeed, analysts peppered
 3
     Defendants with repeated questions about the “headwind” that PubMatic experienced from one of
 4
     its top DSP buyers:
 5
            Matthew Swanson - Rbc Capital Markets - Analyst
 6
            Hey, guys, thanks for taking the question.
 7
            Rajeev, I know sometimes you can’t give us all the details, but anything else you
 8          can kind of tell us about the nature of the change from the DSP just because we
            weren’t hearing this from some peers. And then also – so it sounds like drop in July,
 9          stable in August. What the process is of doing the iterations to optimize activity?
            And then, Steve, if you could just kind of give us the balance between the DSP and
10          the macro and how you were thinking about guidance, that would be great.
11          Rajeev Goel - PubMatic Inc - Chief Executive Officer, Co-Founder, Director
12          Yes. Thank you, Matt.
13          So beginning in July, we saw a headwind emerge from a top DSP buyer, which
            recently shifted a significant number of clients to a new platform that evaluates
14          inventory differently. And so the parameters of how they value inventory have
            changed, and we are working to optimize the inventory that we send this DSP
15          accordingly. In addition, for some of our SPO partners, they did not realize until after
            the changes were made that their SPO strategies were no longer implemented.
16
            And so as a result, they need to reimplement their SPO settings on this DSP’s new
17          platform, and that process takes time. So accordingly, we saw this notable drop in
            spend in July, and then we’ve seen that stabilize in August.
18
            Now given the scale and complexity of our real-time platform, we anticipate that it
19          will take several months to iterate and optimize the traffic that we send to this DSP.
            And so while we’re doing this, a top priority for us is to accelerate the diversification
20          of ad spend on our platform away from legacy DSPs. And we’ve been making
            progress, but we plan to accelerate our strategy. So for instance, in Q2, we expanded
21          the share of spending from DSPs outside of the top 5 with performance marketers
            and mid-tier DSPs growing 20% year over year, such as MNTN and tvScientific and
22          some China-based DSPs. In July, that same cohort accelerated to over 30% year over
            year.
23
            And we think generally that there is significant opportunity as advertiser budgets
24          outside of the top 250 advertisers and their holdco representatives is growing
            significantly faster than the growth rate within that top 250. But it’s clear that the
25          concentration of our legacy DSP relationships is a significant factor that’s
            constraining our growth, and we intend to address that head on.
26
            I’ll turn it over to Steve.

     Case 3:25-cv-07067-JSC          Document 53         Filed 09/04/26     Page 20 of 37


 1          Sure.

 2          With respect to the outlook, Matt, the vast majority of the outlook is being
            influenced by this change by the DSP in July. Just to give you some additional
 3          color. In providing the range, the way that I look at the bottom end of the range, it
            assumes that the latest trends that we’re seeing today continue as such, and there’s
 4          minimal but some consumer softness from the macro. And of course, the upper end
            of the range assumes the mitigation efforts take hold and start to improve that spend,
 5          and there is limited impact from the macro.

 6          And I think the key point to note for investors is that as a business, we are very
            focused on moving quickly. Obviously, we have a bias towards action. We were
 7          surprised. We had limited visibility from this change, but the team is moving very
            quickly. And as we demonstrated with the DSP change that occurred mid last year,
 8          we worked through that.

 9          And as I commented in the prepared comments, we grew that spend for the first time
            in July from that DSP. So we’re confident we’re on the right track.
10
            71.     Analysts continued to question Defendants:
11
            Jason Helfstein - Oppenheimer & Co Inc – Analyst
12
            And what made it like specific to this DSP like best to understand like how you –
13          if your decision on what was valuable inventory was fine for everybody else, why
            was it not fine for this DSP suddenly?
14
            Rajeev Goel - PubMatic Inc - Chief Executive Officer, Co-Founder, Director
15
            Yes. Our view is it was precipitated by a shift in clients that this DSP has from one
16          platform to a different platform, and that shift corresponded with the quarter
            boarder. So we saw that impact starting in July.
17
            72.     One analyst questioned PubMatic further, noting that the platform shift that the
18
     Company was referring to had been “going on for some time:”
19
            Robert Coolbrith - Evercore Inc - Equity Analyst
20
            Great, thank you for taking our questions.
21
            I think the platform shift that you’re talking about has been going on for some
22          time. So just wondering if the triggering event in July was maybe incremental
            changes to that platform or a large number of your SPO customers finally making
23          that transition or something else? And then finally, any indication of a step-up in
            activity around direct connects from that DSP?
24
            And then finally, I guess, second question here would be, if you could just revisit the
25          timelines for potential recovery, both around getting those SPO instructions back up
            and running and optimizing the traffic shaping. If you could just repeat those, that
26          would be great.
27          Thank you.

 1
          Sure. Yeah, hey, Rob.
 2
          So I mean, we certainly saw an uptick or significant increase of this activity from
 3        the DSP causing the drop in spend in July. So I can’t speak to exactly kind of what
          was their timeline or all the history of changes that they made. But that’s what we
 4        observed on our platform, which we are -- again, we’ve stabilized, but are working
          to improve. So there are things that we need to do to shape the traffic accordingly
 5        from our platform more to the liking of that DSP. And so we’re heavily engaged in
          that process.
 6
          And then I’ll turn it over to Steve for the second half of your question.
 7
          Steven Pantelick - PubMatic Inc - Chief Financial Officer
 8
          Yeah, I mean, just to quickly comment on a little bit more on that color, so that
 9        DSP that made that change growing very nicely, double digits in June and then a
          notable decline negative year over year in July. So there was clearly a shift on their
10        side in terms of how they were valuing inventory in terms of what it matters to them
          and how their platform operates.
11
          And remind me the second part, it was --
12
          Robert Coolbrith - Evercore Inc - Equity Analyst
13
          I just say the time line you have most -- with the stabilization in August, does that
14        indicate that most of your SPO customers have sort of gotten those instructions back
          into that platform? And any timeline on the optimization of the traffic shaping and
15        how you’re thinking about how long that could take to sort of get back to normal?
16        Steven Pantelick - PubMatic Inc - Chief Financial Officer
17        Sure.
18        Well, our teams have absolutely been reaching out to all of our SPO partners, letting
          them know that this has happened, that they need to go into this platform and to
19        reupload their SPO parameters. And so that’s just a process that the SPO partners
          have to do on this DSP. So that’s in process and happening. And it’s -- after letting
20        them know, it’s largely in their hands.
21        Now with respect to just the mitigation efforts, when we saw the trends start to really
          decel in July, obviously, we got all the appropriate folks focused on assessing. And
22        what we saw when we had this significant change a year ago that there is a lot of
          iteration and testing that needs to be done because this is an incredibly complex
23        ecosystem. You’re talking about hundreds of billions of impressions a day that we -
          - ourselves are processing. And so it takes testing, iterating and then doing it all over
24        again and seeing what works and does it meet the criteria that’s been established.
25        So our approach is we’re working hard to mitigate it. I incorporated at the low end
          of the outlook an assumption that the mitigation efforts are relatively limited in terms
26        of effectiveness this quarter, and we’re going to keep working at it.
27        I would say that given the important size of this DSP, it’s just going to take time.
          And -- but we are well positioned to continue to work through it. And I really want
28        to emphasize if you step back, this is a situation we have experienced [sic] doing.

 1          The big challenge here was we didn’t have any visibility in terms of the big decel.
            And so we’re obviously reacting pretty quickly.
 2
            Number two, we are in really healthy financial shape. I mean, we have roughly $120
 3          million of cash, no debt. We generate free cash. So we are in this for the long run,
            and we’re confident that we're going to work through this. And in the near term, we
 4          are going to double down on the fastest growing areas that we have, diversify our
            DSP mix, et cetera.
 5
            So we believe we’re on the right track, and we're going to work through this.
 6
            73.     Despite Defendants’ claims that they were “surprised,” analysts continued to press
 7
     Defendants during the 2Q25 Earnings Call:
 8
            Eric Martinuzzi - Lake Street Capital Markets LLC – Analyst
 9
            And then a follow-up regarding just the fact that you guys were surprised that this
10          large partner changed how it valued the inventory you were sending it, is there a
            risk that other DSPs come to this same conclusion? In other words, how close are
11          you to these DSPs where this kind of [issue] comes out of nowhere?
12          Rajeev Goel - PubMatic Inc - Chief Executive Officer, Co-Founder, Director
13          Yeah.
14          I mean, in general, I think we’re pretty close to these DSPs, and it’s certainly our
            goal to be as close to them as possible. And I think it behooves the DSP as well to
15          be continuously sharing feedback with us on what they want to see more of or what
            they want to see less of or how their advertiser requirements and mix is shifting.
16          So I think, in general, we do quite a good job of being close to these DSPs.
17          In this case, we are reacting with limited visibility. So we need to certainly look
            into that and figure out how we can do a better job.
18
            74.     On this news, PubMatic’s stock price fell $2.23, or 21.1%, to close at $8.34 per share
19
     on August 12, 2025, on unusually heavy trading volume.
20

21          75.     On August 12, 2025, Scotiabank Global Equity Research issued an analyst report on

22 PubMatic entitled “2Q25 Recap: Decent Second Qtr. Results, but Overshadowed by Poor Guidance

23 for 3Q.” The report stated, in relevant part, the following:

24          2Q25 Results Beat, while 3Q25 guidance disappoints. As noted above, PUBM posted
            a modest beat, but disappointing guidance. Ex-TTD, we’ve seen largely positive
25          adtech results this quarter, but most have erred on the conservative side when
            presenting guidance. That being said, PUBM’s guidance looks more than just
26          conservative, and the market is voicing its displeasure. PUBM continues to
            emphasize that growth looks good outside of the DSP client that is reducing spend
27          (mgmt. noted that underlying business - that which excludes the revenue from the
            buyer - grew ~19% yoy), but ultimately these aren’t 1x impacts from legal, or a
28          segment sale, or something similar. This is normal course of business operations, and

 1          PUBM could very easily see another client tomorrow reduce spend. It’s helpful for
            investors to know when growth will normalize, but to assume that this couldn’t
 2          happen again should the broader demand environment get tougher would be foolish.
            Additionally, PUBM may be having trouble optimizing for Kokai - we believe some
 3          of the conservatism built in may be related to the learning curve as they optimize for
            the new platform. One last thing to note is that 3Q24 included ~$5M of political
 4          spend - if we assume the midpoint of the guide and back out the political spend,
            revenues would still be declining yoy. We may not get a completely normal revenue
 5          growth cadence for quite a while.

            your decision on what was valuable inventory was fine for everybody else, why was
11          it not fine for this DSP suddenly?
12          Rajeev Goel - PubMatic Inc - Chief Executive Officer, Co-Founder, Director
13          Yes. Our view is it was precipitated by a shift in clients that this DSP has from one
            platform to a different platform, and that shift corresponded with the quarter boarder.
14          So we saw that impact starting in July.
15          80.     Importantly, CEO Goel did not claim that the shift in clients that this DSP had from
16 one platform to a different platform occurred in July 2025. Rather, CEO Goel stated that PubMatic

17 purportedly saw the impact of that shift in July 2025. Indeed, on June 6, 2023, The Trade Desk

18 issued a press release entitled “The Trade Desk Launches Kokai – a New Media Buying Platform

19 that Brings the Full Power of AI to Digital Marketing” which indicated that the shift that CEO Goel

20 was referring to that The Trade Desk made from Solimar to Kokai occurred in 2023. CEO Goel’s

21 statement, therefore, corroborates the account of CW1, who stated that CEO Goel attended the

22 Company’s global meetings and weekly product management meetings in which discussions were

23 held regarding the shift in clients that The Trade Desk experienced from one platform to a different

24 platform that occurred long before PubMatic purportedly observed the financial impact of that shift

25 in July 2025.

26                     The Insider Selling Supports a Strong Inference of Scienter
27          81.     The stock sales made by CEO Goel and CFO Pantelick during the Class Period add

28 to a strong inference of scienter considering the amount and percentage of shares sold, the timing of

 1 the sales, and their prior trading history. Specifically, during the Class Period, CEO Goel sold

 2 361,214 shares of PubMatic stock for proceeds of $4,122,646. These sales constituted 94% of CEO

 3 Goel’s holdings. Additionally, during the Class Period, CFO Pantelick sold 73,733 shares of

 4 PubMatic stock for proceeds of $794,418. These sales constituted 71% of Pantelick’s holdings.

 5         82.    Indeed, during the Class Period, CEO Goel and CFO Pantelick made the following

 6 sales of Company stock:

 7     •   On April 1, 2025, CEO Goel sold 25,000 shares of PubMatic stock at an average
           share price of $9.14 for proceeds of $228,500;
 8
       •   On April 2, 2025, CEO Goel sold 33,213 shares of PubMatic stock at an average
 9         share price of $9.31 for proceeds of $309,213;
10
       •   On May 5, 2025, CEO Goel sold 25,000 shares of PubMatic stock at an average share
11         price of $9.84 for proceeds of $246,000;

12     •   On June 2, 2025, CEO Goel sold 25,000 shares of PubMatic stock at an average share
           price of $11.80 for proceeds of $295,000;
13
       •   On June 9, 2025, CEO Goel sold 44,000 shares of PubMatic stock at an average share
14         price of $12.13 for proceeds of $533,720;
15     •   On June 23, 2025, CEO Goel sold 44,000 shares of PubMatic stock at an average
16         share price of $11.02 for proceeds of $484,880;

17     •   On July 2, 2025, CEO Goel sold 33,001 shares of PubMatic stock at an average share
           price of $12.56 for proceeds of $414,493;
18
       •   On July 7, 2025, CEO Goel sold 44,000 shares of PubMatic stock at an average share
19         price of $12.53 for proceeds of $551,320;
20     •   On July 21, 2025, CEO Goel sold 44,000 shares of PubMatic stock at an average
21         share price of $12.80 for proceeds of $563,200;

22     •   On August 1, 2025, CEO Goel sold 44,000 shares of PubMatic stock at an average
           share price of $11.28 for proceeds of $496,320;
23
       •   On March 3, 2025, CFO Pantelick sold 4,000 shares of PubMatic stock at an average
24         share price of $10.61 for proceeds of $42,440;
25     •   On April 2, 2025, CFO Pantelick sold 12,061 shares of PubMatic stock at an average
           share price of $9.31 for proceeds of $112,288;
26

27     •   On April 3, 2025, CFO Pantelick sold 18,384 shares of PubMatic stock at an average
           share price of $8.45 for proceeds of $155,345;

                                                  24


     Case 3:25-cv-07067-JSC          Document 53        Filed 09/04/26     Page 26 of 37


 1      •   On May 5, 2025, CFO Pantelick sold 4,000 shares of PubMatic stock at an average
            share price of $9.83 for proceeds of $39,320;
 2
        •   On June 3, 2025, CFO Pantelick sold 4,000 shares of PubMatic stock at an average
 3          share price of $12.07 for proceeds of $48,280;
 4
        •   On July 2, 2025, CFO Pantelick sold 15,598 shares of PubMatic stock at an average
 5          share price of $12.54 for proceeds of $195,599; and

 6      •   On July 3, 2025, CFO Pantelick sold 15,690 shares of PubMatic stock at an average
            share price of $12.82 for proceeds of $201,146.
 7
            83.     The timing of these sales also supports a strong inference of scienter. For example,
 8
     on March 3, 2025 – only four days after PubMatic issued its 2024 Form 10-K – CFO Pantelick sold
 9
     4,000 shares of PubMatic stock at an average share price of $10.61 for proceeds of $42,440.
10
     Additionally, CEO Goel and CFO Pantelick sold substantial amounts of PubMatic stock on the same
11
     days. For example, on April 2, 2025 – CEO Goel sold 33,213 shares of PubMatic stock at an average
12
     share price of $9.31 for proceeds of $309,213. On the same day, CFO Pantelick sold 12,061 shares
13
     of PubMatic stock at an average share price of $9.31 for proceeds of $112,288. Similarly, on May
14
     5, 2025, CEO Goel sold 25,000 shares of PubMatic stock at an average share price of $9.84 for
15
     proceeds of $246,000. On the same day, CFO Pantelick sold 4,000 shares of PubMatic stock at an
16
     average share price of $9.83 for proceeds of $39,320. Moreover, on July 2, 2025, CEO Goel sold
17
     33,001 shares of PubMatic stock at an average share price of $12.56 for proceeds of $414,493. On
18
     the same day, CFO Pantelick sold 15,598 shares of PubMatic stock at an average share price of
19
     $12.54 for proceeds of $195,599.
20
            84.     The stock sales by CEO Goel and CFO Pantelick were also unusual considering their
21
     prior trading histories. For instance, between February 26, 2024 and August 8, 2024, CFO Pantelick
22
     sold 43,281 shares of PubMatic stock for proceeds of $949,345 – proceeds that amounted to only
23
     41% of his holdings compared to sales amounting to 71% of his holdings during the Class Period.
24
     And although CEO Goel sold 257,056 shares of PubMatic stock between February 26, 2024 and
25
     August 8, 2024 for proceeds of $5,172,690, such sales did not occur during a period in which
26
     Plaintiff alleges that the Company’s stock was artificially inflated because of Defendants’
27
     misrepresentations. Thus, these stock sales add to the strong inference of scienter alleged.

     Case 3:25-cv-07067-JSC         Document 53       Filed 09/04/26     Page 27 of 37


 1         The Core Operations Inference Bolsters the Strong Inference of Scienter Alleged

 2          85.    The core operations inference also adds to the strong inference of scienter alleged

 3 because the facts relate to issues about which CEO Goel would have been aware. For example, The

 4 Trade Desk was one of PubMatic’s top two partners, which together account for more than 50% of

 5 platform spending for the Company. Additionally, CEO Goel participated in meetings in which

 6 issues related to The Trade Desk were discussed. For instance, CW1 stated that in 2024, PubMatic

 7 saw a big impact on monetization because of the Company’s problems with DSPs in general, and

 8 with The Trade Desk in particular, and that it “was clear” that PubMatic was not growing as fast as

 9 it had in previous years. CW1 stated that CEO Goel was aware of problems with revenue
10 optimization with The Trade Desk because he participated in both the Company’s global meetings

11 and weekly product management meetings during which the participants discussed these issues.

12 CW1 stated further that PubMatic’s problems with DSPs in general – and with The Trade Desk in

13 particular – were also discussed in weekly product management meetings. During PubMatic’s

14 weekly product management meetings, CW1 stated that the participants at the meetings spent almost

15 all of 2024 trying to ascertain how to get revenue from DSPs to stop leaking.

16          86.    Indeed, CW1 stated that during these meetings, the issues discussed related to the
17 declines in the Company’s revenue were “pervasive.” For example, CW1 stated that in 2024, the

18 participants at the weekly product management meetings determined that PubMatic did not perform

19 well with video inventory in the new area of CTV, which sustained premium rates. According to

20 CW1, everything else became just a commodity and was considered “cheap.” CW1 stated that the

21 Company’s competitors like Magnite focused on developing video inventory, which was

22 “premium.” In contrast, according to CW1, PubMatic maintained its historical focus on banner

23 advertisements, which had accounted for much of the Company’s revenue in previous years.

24          87.     CW1 also indicated that during the Company’s weekly product management
25 meetings going back to 2024, there were huge projects around the reprioritization of traffic to The

26 Trade Desk. CW1 described that in digital advertising, typically the technology involved will favor

27 making money at any cost. However, according to CW1, to address the leakage of revenue related

28 to The Trade Desk, PubMatic optimized things in favor of The Trade Desk to the point that the

                             SECOND AMENDED CLASS ACTION COMPLAINT

     Case 3:25-cv-07067-JSC         Document 53       Filed 09/04/26     Page 28 of 37


 1 Company was “giving away money” to The Trade Desk. For example, CW1 stated that PubMatic’s

 2 customer success team created huge projects in 2024 intended to make the Company’s inventory

 3 attractive to The Trade Desk. According to CW1, however, these projects merely consisted of

 4 cutting PubMatic’s margins by 20-30% to give The Trade Desk a discounted rate to try to win back

 5 business from The Trade Desk. CW1 stated that CEO Goel oversaw these strategies to try to win

 6 back business from The Trade Desk. As a result, CW1 stated that it was clear to participants at the

 7 Company’s weekly product management meetings in 2024 that PubMatic was “in a lot of danger”

 8 because of the Company’s problems with The Trade Desk.

 9          88.    Additionally, CW1 stated that during PubMatic’s weekly product management
10 meetings, the participants discussed the fact that The Trade Desk was prioritizing competitors who

11 were more competent in CTV, and that these market shifts drastically affected the value of the

12 Company’s existing inventory. According to CW1, as a result, banner ads became “cheap” and

13 were increasingly considered “junky.” Thus, in 2024, CW1 stated that PubMatic’s banner inventory

14 that had previously sold for $50 each would bring in less than one dollar.

15          89.    CW1 stated further that during PubMatic’s weekly product management meetings in
16 2024, CEO Goel was furious at The Trade Desk because The Trade Desk had cut off PubMatic.

17 CW1 stated that the Company’s monetization team had asked CEO Goel to intervene to address the

18 problems that PubMatic was experiencing with The Trade Desk. CW1 stated that during the

19 Company’s weekly product management meetings that CW1 and CEO Goel attended, the

20 Company’s monetization, product, and customer success teams met to discuss how PubMatic could

21 mitigate the negative financial impacts from The Trade Desk’s decision to circumvent business

22 around PubMatic.

23          90.    CW1 also stated that during a weekly product management meeting in 2024, CEO
24 Goel was demoralized while conveying a conversation he had with The Trade Desk. Specifically,

25 CEO Goel told the meeting participants that The Trade Desk told CEO Goel that PubMatic “just

26 wasn’t big enough for The Trade Desk to care about.”

27          91.    Additionally, CW1 stated that Janes, Jamdade, and CW1 frequently voiced concerns
28 during the weekly product management meetings regarding these issues. CW1 stated that Janes, in

                             SECOND AMENDED CLASS ACTION COMPLAINT

 1 particular, was “very vocal” during these meetings in stating that the Company’s publishing demand

 2 was decreasing and that PubMatic faced serious challenges related to revenue as a result.

 3                   The Account of CW1 Supports a Strong Inference of Scienter

 4          92.    As set forth in detail above, the account of CW1 demonstrates that CEO Goel knew,

 5 or was deliberately reckless in not knowing, of the falsity of Defendants’ statements and

 6 misrepresentations to investors.

 7                          Plaintiff Adequately Alleges Corporate Scienter

 8          93.    As a corporation, PubMatic acted, and could only have acted, through its employees

 9 and agents. Accordingly, the scienter of the Company’s senior controlling officers may be attributed
10 to PubMatic itself to establish liability as a primary violator of the Exchange Act if such senior

11 officials were acting within the scope of their apparent authority. At all times relevant herein, CEO

12 Goel and CFO Pantelick were senior controlling officers of PubMatic and were acting within the

13 scope of their apparent authority.

14                                       Post Class Period Events
15          94.    On August 13, 2025, Investing.com published an article entitled “PubMatic’s SWOT

16 analysis; adtech firm navigates DSP headwinds amid CTV growth.” The article stated in relevant

17 part the following with respect to PubMatic: “a new headwind emerged from a major Demand-Side

18 Platform (DSP) partner, suspected to be The Trade Desk (NASDAQ:TTD), due to a platform change

19 from Solimar to Kokai. This change affected how inventory is valued and led to a decline in year-

20 over-year spend in July after experiencing double-digit growth in June. The impact of this DSP

21 partner change has been significant enough for PubMatic to adjust its future revenue and EBITDA

22 guidance.”

23                                 CLASS ACTION ALLEGATIONS

24          95.    Plaintiff brings this action as a class action pursuant to Rules 23(a) and 23(b)(3) of

25 the Federal Rules of Civil Procedure on behalf of a class consisting of all those who purchased the

26 Company’s common stock during the Class Period, and who were damaged thereby (“Class”).

27 Excluded from the Class are: (a) persons and entities that suffered no compensable losses; and (b)(i)

28 Defendants; (ii) any person who served as a partner, control person, officer, and/or director of the

                             SECOND AMENDED CLASS ACTION COMPLAINT
                                                     28


     Case 3:25-cv-07067-JSC            Document 53      Filed 09/04/26     Page 30 of 37


 1 Company during the Class Period, and members of their immediate families; (iii) present and former

 2 parents, subsidiaries, assigns, successors, affiliates, and predecessors of the Company; (iv) any

 3 entity in which the Defendants have or had a controlling interest; (v) any trust of which an Individual

 4 Defendant is the settler or which is for the benefit of an Individual Defendant and/or member(s) of

 5 their immediate families; (vi) Defendants’ liability insurance carriers; and (vii) the legal

 6 representatives, heirs, successors, and assigns of any person or entity excluded under provisions (i)

 7 through (vi) hereof.

 8          96.    The members of the Class are so numerous that joinder of all members is

 9 impracticable. Throughout the Class Period, the Company’s common stock was actively traded on
10 the NASDAQ exchange. While the exact number of Class members is unknown to Plaintiff at this

11 time and can only be ascertained through appropriate discovery, Plaintiff believes that there are

12 hundreds or thousands of members in the proposed Class. Record owners and other members of the

13 Class may be identified from records maintained by the Company or its transfer agent and may be

14 notified of the pendency of this action by mail, using the form of notice similar to that customarily

15 used in securities class actions.

16          97.    Plaintiff’s claims are typical of the claims of the members of the Class, since all
17 members of the Class are similarly affected by Defendants’ wrongful conduct in violation of federal

18 law alleged herein.

19          98.    Plaintiff will fairly and adequately protect the interests of the members of the Class
20 and has retained counsel competent and experienced in class action and securities litigation.

21          99.    Common questions of law and fact exist as to all members of the Class and
22 predominate over any questions solely affecting individual members of the Class. Among the

23 questions of law and fact common to the Class are:

24                 (1)     whether Defendants’ acts constituted violations of the federal securities laws;
25                 (2)     whether Defendants’ statements made to the investing public during
26                         the Class Period misrepresented material facts concerning the
27                         Company’s business, operations, and financial condition;

                              SECOND AMENDED CLASS ACTION COMPLAINT
                                                      29


     Case 3:25-cv-07067-JSC          Document 53        Filed 09/04/26    Page 31 of 37


 1                  (3)     whether the price of the Company’s common stock was artificially

 2                          inflated during the Class Period; and

 3                  (4)     to what extent the members of the Class have sustained damages and

 4                          the proper measure of damages.

 5           100.   A class action is superior to all other available methods for the fair and efficient

 6 adjudication of this controversy since joinder of all members is impracticable. Furthermore, as the

 7 damages suffered by individual Class members may be relatively small, the expense and burden of

 8 individual litigation make it impossible for members of the Class to individually redress the wrongs

 9 done to them. Additionally, there will be no difficulty in the management of this action as a class
10 action.

11                                          LOSS CAUSATION
12           101.   As detailed herein, during the Class Period Defendants engaged in a scheme to
13 deceive the market and a course of conduct that artificially inflated the price of the Company’s

14 common stock. Defendants’ conduct, moreover, operated as a fraud or deceit on Class Period

15 purchasers of the Company’s common stock by failing to disclose, and misrepresenting, the adverse

16 facts detailed herein.     As Defendants’ prior misrepresentations and fraudulent conduct were
17 disclosed and became apparent to the market, the price of the Company’s common stock declined

18 significantly as the prior artificial inflation dissipated from the Company’s common stock.

19           102.   Specifically, on August 11, 2025, PubMatic released its second quarter 2025
20 financial report. In the Company’s report, Defendants revealed that the Company’s outlook

21 reflected “a reduction in ad spend from one of [its] top DSP partners.” Defendants further revealed

22 that a “top DSP buyer” had “shifted a significant number of clients to a new platform that evaluates

23 inventory differently” causing significant headwinds. On this news, PubMatic’s stock price fell

24 $2.23, or 21.1%, to close at $8.34 per share on August 12, 2025, on unusually heavy trading volume.

25           103.   As a direct result of Defendants’ misstatements and omissions alleged herein, the
26 price of the Company’s common stock was higher than it would have been but for Defendants’

27 misrepresentations and half-truths.       Specifically, Defendants’ misstatements and half-truths
28

                              SECOND AMENDED CLASS ACTION COMPLAINT
                                                      30


     Case 3:25-cv-07067-JSC           Document 53         Filed 09/04/26   Page 32 of 37


 1 increased the price of the Company’s common stock, maintained the price, and/or prevented a

 2 greater decrease in the price.

 3           104.   As a result of the purchases of the Company’s common stock during the Class Period,

 4 Plaintiff and the other members of the Class suffered economic loss (damages) under the federal

 5 securities laws.

 6           105.   By concealing from investors the adverse facts detailed herein, Defendants presented

 7 a misleading picture of the Company’s business and prospects. As the truth regarding the Company

 8 was revealed to the market, the price of the Company’s common stock fell significantly. These

 9 declines removed the inflation from the price of the Company’s common stock, causing real
10 economic loss to investors who purchased the Company’s common stock during the Class Period.

11           106.   The declines in the price of the Company’s common stock after the corrective
12 disclosures came to light were a direct result of the nature and extent of Defendants’ fraudulent

13 misrepresentations being revealed to investors and the market. The timing and magnitude of the

14 price declines in the Company’s common stock negate any inference that the loss suffered by

15 Plaintiff and the other Class members was caused by changed market conditions, macroeconomic,

16 or industry factors, or by Company-specific facts unrelated to Defendants’ fraudulent conduct.

17           107.   Additionally, the adverse financial impacts that PubMatic experienced in July 2025,
18 including, but not limited to, a significant reduction in advertising spend from The Trade Desk and

19 reduced revenue and EBITDA guidance, represented a materialization of the risks that CEO Goel

20 knew about, or was deliberately reckless in not knowing, since at least 2024 as alleged more fully

21 herein.

22           108.   Moreover, Defendants’ risk disclosures that constituted purported warnings
23 regarding risks that might cause harm to PubMatic’s business in the future implicitly served as

24 representations regarding the Company’s present state of affairs.         Indeed, because the risk
25 disclosures suggested that the circumstances posing the risks had not yet occurred, such disclosures

26 functioned as representations about PubMatic’s present state of affairs. As a result, and as alleged

27 more fully herein, such risk disclosures created an impression that differed in a material way from

28 the present state of affairs that actually existed.

                               SECOND AMENDED CLASS ACTION COMPLAINT
                                                         31


     Case 3:25-cv-07067-JSC          Document 53        Filed 09/04/26     Page 33 of 37


 1          109.   Thus, the economic loss (damages) suffered by Plaintiff and the other Class members

 2 was a direct result of Defendants’ fraudulent scheme to artificially inflate the price of the Company’s

 3 common stock and the subsequent significant decline in the value of the Company’s common stock

 4 when Defendants’ prior misrepresentations and other fraudulent conduct were revealed.

 5                     APPLICABILITY OF PRESUMPTION OF RELIANCE:
                             FRAUD ON THE MARKET DOCTRINE
 6

 7          110.   At all relevant times, the market for the Company’s common stock was an efficient

 8 market for the following reasons, among others:

 9          111.   The Company’s common stock met the requirements for listing, and was listed and
10 actively traded on the NASDAQ exchange, a highly efficient, electronic stock market;

11          112.   As a regulated issuer, the Company filed periodic public reports with the SEC and
12 the NASDAQ exchange;

13          113.   The Company regularly communicated with public investors via established market
14 communication mechanisms, including regular disseminations of press releases on the national

15 circuits of major newswire services and other wide-ranging public disclosures, such as

16 communications with the financial press and other similar reporting services; and

17          114.   The Company was followed by securities analysts employed by major brokerage
18 firms who wrote reports that were distributed to the sales force and certain customers of their

19 respective brokerage firms. Each of these reports was publicly available and entered the public

20 marketplace.

21          115.   As a result of the foregoing, the market for the Company’s common stock promptly
22 digested current information concerning the Company from all publicly available sources and

23 reflected such information in the prices of the Company’s common stock.                  Under these
24 circumstances, all purchasers of the Company’s common stock during the Class Period suffered

25 similar injury through their purchase of the Company’s common stock at artificially inflated prices

26 and a presumption of reliance applies.

     Case 3:25-cv-07067-JSC         Document 53        Filed 09/04/26     Page 34 of 37


 1                                         NO SAFE HARBOR

 2          116.    The statutory safe harbor provided for forward-looking statements under certain

 3 circumstances does not apply to any of the allegedly false statements alleged herein. Many of the

 4 specific statements alleged herein were not identified as “forward-looking statements” when made

 5 and thus are not entitled to protection under the safe harbor provision. Additionally, to the extent

 6 that there were any forward-looking statements, there were no meaningful cautionary statements

 7 identifying important factors that could cause actual results to differ materially from those in the

 8 purportedly forward-looking statements. Alternatively, to the extent that the statutory safe harbor

 9 does apply to any forward-looking statements alleged herein, Defendants are liable for those false
10 forward-looking statements because at the time each of those forward-looking statements were

11 made, the particular speaker knew that the particular forward-looking statement was false, and/or

12 the forward-looking statement was authorized and/or approved by an executive officer of the

13 Company who knew that those statements were false when made.

14                                             COUNT I
           Violation of Section 10(b) of the Exchange Act and SEC Rule 10b-5 Promulgated
15                                Thereunder Against All Defendants
16          117.    Plaintiff repeats and realleges each and every allegation contained above as though
17 set forth in full herein.

18          118.    During the Class Period, Defendants disseminated or approved the materially false
19 and misleading statements specified above, which they knew, or were deliberately reckless in not

20 knowing, were misleading. These statements were false and misleading because they contained

21 misrepresentations and failed to disclose material facts necessary to make the statements made, in

22 light of the circumstances under which they were made, not misleading.

23          119.    To the extent that the claims alleged herein are based upon the omission of
24 information, such omissions were made in connection with the misrepresentations and misleading

25 half-truths alleged herein and were not based upon pure omissions.

26          120.    Defendants: (1) employed devices, schemes, and artifices to defraud; (2) made untrue
27 statements of material fact/and or omitted to state material facts necessary to make the statements

                               SECOND AMENDED CLASS ACTION COMPLAINT
                                                     33

 1 made not misleading; and (3) engaged in acts, practices, and a course of business that operated as a

 2 fraud and deceit upon the purchasers of the Company’s common stock during the Class Period.

 3          121.    Plaintiff and the Class have suffered damages in that, in reliance on the integrity of

 4 the market, they paid artificially inflated prices for the Company’s common stock. Plaintiff and the

 5 Class would not have purchased the Company’s common stock at the prices they paid – or at all –

 6 if they had been aware that the market prices had been artificially and falsely inflated by Defendants’

 7 misleading statements.

 8          122.    As a direct and proximate result of Defendants’ wrongful conduct, Plaintiff and the

 9 other members of the Class suffered damages in connection with their purchases of the Company’s
10 common stock during the Class Period.

11                                              COUNT II
                    Violation of Section 20(a) of the Exchange Act Against CEO Goel
12

13          123.    Plaintiff repeats and realleges each and every allegation contained above as though
14 set forth in full herein.

15          124.    CEO Goel acted as a controlling person of the Company within the meaning of
16 Section 20(a) of the Exchange Act as alleged herein. By virtue of his high-level position and his

17 ownership and contractual rights, participation in, and/or awareness of the Company’s operations

18 and/or intimate knowledge of the Company’s statements filed with the SEC and disseminated to the

19 investing public, CEO Goel had the power to influence and control, and did influence and control,

20 directly or indirectly, the decision-making of the Company, including the content and dissemination

21 of the various statements alleged to be false and misleading herein.

22          125.    CEO Goel, moreover, was provided with, or had unlimited access to, copies of the
23 Company’s reports, press releases, public filings, and other statements alleged to be false and

24 misleading herein. CEO Goel was provided with, or had unlimited access to, such documents and

25 statements prior to, and/or shortly after these statements were issued, and therefore had the ability

26 to prevent the issuance of the statements and/or cause the statements to be corrected. Additionally,

27 CEO Goel had direct and supervisory involvement in the day-to-day operations of the Company and

     Case 3:25-cv-07067-JSC          Document 53         Filed 09/04/26   Page 36 of 37


 1 had the power to control or influence the particular transactions giving rise to the securities

 2 violations.

 3          126.   CEO Goel also had ultimate authority over the Company’s statements, including

 4 controlling the content of such statements and whether and how to communicate such statements to

 5 the public. Thus, CEO Goel is liable pursuant to Section 20(a) of the Exchange Act.

 6                                       PRAYER FOR RELIEF

 7          WHEREFORE, Plaintiff prays for relief and judgment, as follows:

 8          A.     Determining that this action is a proper class action, designating Plaintiff as Lead

 9 Plaintiff, and certifying Plaintiff as a Class representative under Rule 23 of the Federal Rules of
10 Civil Procedure and Plaintiff’s counsel as Lead Counsel;

11          B.     Awarding compensatory damages in favor of Plaintiff and the other Class members
12 against all Defendants, jointly and severally, for all damages sustained because of Defendants’

13 wrongdoing, in an amount to be proven at trial, including interest thereon;

14          C.     Awarding Plaintiff and the Class their reasonable costs and expenses incurred in this
15 action, including counsel fees and expert fees; and

16          D.     Such other and further relief as the Court may deem just and proper.
17                                           JURY DEMAND
18          Plaintiff hereby demands a trial by jury.
