Even if our content is effectively matched with advertisements or client offerings, our current clients may not continue to place marketing spend or advertisements on our websites or our third-party publisher or strategic partner websites. For example, macroeconomic conditions such as an economic downturn, a recession in the United States or other countries, a public health crises such as the COVID-19 pandemic and geopolitical conflicts such as the Russia-Ukraine military conflict and the Israel-Hamas war have impacted, and may continue to impact, our clients’ marketing spend in the short-term and potentially in the long-term. If any of our clients decide not to continue to place marketing spend or advertisements on our owned and operated websites or on our third-party publisher or strategic partner websites, we could experience a rapid decline in our revenue over a relatively short period of time. Any factors that limit the amount our clients are willing to and do spend on marketing or advertising with us, or to purchase marketing results from us, could have a material adverse effect on our business, financial condition, operating results and cash flows.

Furthermore, a substantial portion of our revenue is generated from a limited number of clients, including one client that accounted for 27% of our net revenue for three months ended March 31, 2025, and two clients that accounted 23% and 13% of our net revenue for nine months ended March 31, 2025. Our clients can generally terminate their contracts with us at any time or pause marketing spending without contract termination, and they do not have minimum spend requirements. Clients may also fail to renew their contracts or reduce their level of business with us, leading to lower revenue.

Worldwide economic conditions remain uncertain due to various global disruptions, including geopolitical events, such as war, the threat of war (including collateral damage from cyberwarfare and targeted security attacks), terrorist activity, natural disasters, climate change and extreme-weather related events, power shortages or outages, major public health issues, including pandemics, and significant local, national, or global events capturing the attention of a large part of the population, which could prevent or hinder our, our third-party publishers’ or our clients’ ability to do business, increase our costs, and negatively affect our stock price. Adverse consequences resulting from increasing economic or political conflicts between the United States and China, Russia’s invasion of Ukraine and the subsequent economic sanctions imposed by the U.S., NATO and other countries, the Israel-Hamas war and the possible expansion of such conflict in the surrounding areas, and various other market issues may have broader implications on economies outside of their respective regions, including increased instability in the worldwide financial markets and economy, increases in inflation, recessionary economic cycles, and enhanced volatility in foreign currency exchange rates. These uncertainties have in the past and may in the future cause our clients or potential clients to delay or reduce spending, which could negatively impact our revenue and operating results and make it difficult for us to accurately plan future business activities.

Notwithstanding the decision from the U.S. Court of Appeals for the Eleventh Circuit, the new rules allow the FCC to “red flag” certain numbers, requiring mobile carriers to block texts from those numbers. The rules also codify that the national Do-Not-Call list protections apply to text messaging, making it illegal for marketing texts to be sent to numbers on the national Do-Not-Call registry absent an applicable exception. The FCC order adopting the new rules also encourages providers to make email-to-text messages an opt-in service for end users.

These new rules pertaining to text messaging took effect on March 26, 2024. The “one-to-one” and “logically and topically associated” consent rule, which has been appealed, is now scheduled to take effect on January 26, 2026, absent judicial intervention. The “red flag” blocking requirements requiring mobile wireless providers to block texts from phone numbers on a “reasonable” do-not-originate list and a similar rule which requires mobile wireless providers to block texts from numbers identified by the FCC through its Enforcement Bureau took effect in 2024.

Previous wording

February 2024, the FCC adopted new rules governing the ability of call and text message recipients to revoke consent previously given and thereby “opt-out” of receiving future calls and text messages from a sender. These new rules specify when a call or text message recipient’s consent must be considered revoked and create certain presumptions about other forms of consent revocation that a sender of a call or text message can rebut pursuant to a totality of circumstances test administered by the FCC or a court. They also require valid consent revocations to be honored within a reasonable period not to exceed ten business days from receipt of such request. Additionally, when a recipient has consented to several categories of text messages from a sender and opt-out of a text message from that sender, the new rules permit a sender to seek to clarify the scope of the opt-out request through a one-time opt-out confirmation text message. This rule permitting a sender to seek such clarification through a one-time opt-out confirmation text message took effect on April 4, 2024. On April 7, 2025, the FCC issued a stay of the portion of the consent revocation rules requiring opt-outs across all channels and for all purposes in response to a consumer’s “STOP” request. The remaining proposed consent revocation rules regarding the ten-day revocation window and text responses took effect on April 11, 2025.

The FCC rules could have a material adverse impact on our media sources and our clients, especially smaller businesses, as they may not be able to continue to participate in, or may substantially reduce their participation in, the online advertising channel due to increased costs, technological compliance challenges and additional legal risks, including potential liabilities or claims relating to compliance. Decreased participation in online advertising by our media sources or clients as a result of the rules could have a material adverse impact on our business, results of operation and financial condition, as it may reduce the availability to us of qualified inquiries. Moreover, our business could be materially and adversely affected directly by the FCC’s rules, as we also generate a substantial portion of our revenue from our own operation of websites to generate qualified inquiries. While some of the rules become effective in 2025, recommendations for best practices from associations such as the Cellular Telecommunications Industry Association (“CTIA”) may encourage mobile wireless carriers to require senders of SMS or text messages to comply with the amended rules ahead of the applicable effective dates. In addition, wireline and mobile wireless carriers or their service providers could elect to impose additional requirements, including with respect to prerecorded calls and the use of short codes and ten-digit long codes to transmit or receive text messages, which could have the effect of hindering our ability to contact consumers, which could have a material adverse effect on our business. The scope and application of these rules and related industry practices may be subject to changes and uncertainties. The operation of or compliance with the rules and related industry practices may decrease our revenues or increase our costs. In addition, any failure by us or our media sources or clients to comply with such laws and practices may subject us to significant liabilities.

Historically, quarterly and annual results of operations have fluctuated due to changes in our business, our industry and the general economic and regulatory climate. We expect our future results of operations to vary significantly from quarter to quarter due to a variety of factors, many of which are beyond our control. For example, pandemics such as the COVID-19 pandemic and geopolitical conflicts such as the Russian-Ukraine military conflict and the Israel-Hamas war, have previously, and may over the longer term, make our results of operations difficult to predict, especially for our credit-driven businesses. Furthermore, changes in monetary or fiscal policy as the result of pandemics, military conflicts or otherwise may have consequences to our businesses, including our credit-driven businesses, which are unprecedented or otherwise difficult to predict. Our fluctuating results of operations could cause our performance and outlook to be below the expectations of securities analysts and investors, causing the price of our common stock to decline. Our business changes and evolves over time, and, as a result, our historical results of operations may not be useful to you in predicting our future results of operations. Factors that may increase the volatility of our results of operations include, but are not limited to, the following:

Acquisitions have historically been, and continue to be, an important element of our overall corporate strategy and use of capital. In addition, we regularly review and assess strategic alternatives in the ordinary course of business, including potential acquisitions, investments or divestitures. These potential strategic alternatives may result in a wide array of potential strategic transactions that could be material to our financial condition and results of operations. For example, we acquired AquaVida in fiscal year 2024, Modernize, Mayo Labs and FCE in fiscal year 2021, and AmOne, CCM and MBT in fiscal year 2019. Furthermore, we divested our education client vertical in fiscal year 2021, and we divested our B2B client vertical, our businesses in Brazil consisting of QuinStreet Brasil Online Marketing e Midia Ltda (“QSB”)and VEMM, LLC (“VEMM”) along with its interests in EDB, and our mortgage client vertical in the second half of fiscal year 2020.

Our board of directors canceled the prior stock repurchase program that commenced in July 2017 and in April 2022 authorized a new stock repurchase program allowing the repurchase of up to $40.0 million worth of common stock. As of March 31, 2025, approximately $16.8 million remained available for stock repurchases pursuant to the board authorization. The timing and actual number of shares repurchased will depend on a variety of factors including the price, cash availability and other market conditions. The stock repurchase program, authorized by our board of directors, does not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares. The stock repurchase program could affect the price of our stock and increase volatility and may be suspended or terminated at any time, which may result in a decrease in the trading price of our stock. The existence of our stock repurchase program could also cause the price of our common stock to be higher than it would be in the absence of such a program and could potentially reduce the market liquidity for our common stock. Additionally, repurchases under our stock repurchase program will diminish our cash reserves. There can be no assurance that any stock repurchases will enhance stockholder value because the market price of our common stock may decline below the levels at which we repurchased such shares. Any failure to repurchase shares after we have announced our intention to do so may negatively impact our reputation and investor confidence in us and may negatively impact our stock price. Although our stock repurchase program is intended to enhance long-term stockholder value, short-term stock price fluctuations could reduce the program’s effectiveness.

As of September 30, 2025, approximately $9.7 million remained available for stock repurchases pursuant to the board authorization. On October 30, 2025, the Board of Directors authorized a new stock repurchase program allowing the Company to repurchase up to $40.0 million of its outstanding shares of common stock. Repurchases under this program may take place in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. There is no guarantee as to the exact number of shares that will be repurchased by us, and we may discontinue repurchases at any time.
