In April this year, a huge data breach exposed customer data from SK Telecom, one of the leading mobile carriers in South Korea. This massive cybersecurity incident prompted huge backlash among the user base and caused several public authorities to fine the company for insufficient customer data protection. Unsurprisingly, thousands of subscribers switched to competitors, resulting in a one million MNO SIM loss in just one quarter. SK Telecom’s Q2 results were thus highly anticipated, as the impact of the cybersecurity incident on the company’s financials was not easily measurable. It mainly consisted of two things. First, as the mobile subscriber base shrunk by 3%, total revenue slightly decreased (2.6% QoQ). Second, operating expenses grew by 2.9%, resulting from the implementation of several measures following government notice. These included increased cybersecurity efforts as well as commercial compensations to customers, such as free SIM card replacements and tariff discounts. Both evolutions similarly impacted SK Telecom’s financial performance, driving operating income down by 41%, and thus net income down by 75% QoQ. Such low results contrast with the usually solid performance of SK Telecom, but could mark the start of a new era for the company, despite investments made by SK Telecom to keep subscribers while avoiding similar incidents in the future. On the one hand, extraordinary expenses linked to the incident are expected to decrease as soon as possible for SK Telecom. On the other hand, the current subscriber base will not return to its past stage by itself, thus slashing total revenues in the long run. Whether churned out subscribers will come back to the mobile carrier is unsure, even more when considering the past few years. Indeed, SK Telecom has steadily lost market shares on the mobile market for already some time. Its share of mobile subscribers has gone down from 34.4% in Q1 2024 to 33.2% a year later, and 31.7% in Q2. The gap with LG Uplus, its main challenger, has never been so small. Therefore, the incident could potentially accelerate this trend and impact SK Telecom’s position more than just in the short run. South Korean carriers have long operated in a mature market, where growth has mainly come from 5G or M2M lately. As market saturation looms large, growth potential shrinks and brand image becomes increasingly critical to secure substantial market share and generate constant to growing revenue. At first sight, SK Telecom has released resilient quarterly results considering its tough Q2. However, consequences could last longer than expected.
