Rakuten swings to profit but loses KDDI roaming deal

First operating profit in seven years Rakuten posted a ¥50.4bn operating profit, its first in seven years, as shopping, financial services, and mobile losses improved. This shows the core business is finally turning around.
This is a major positive event that directly boosts investor confidence and the stock price.
KDDI ends roaming deal KDDI ended its roaming deal with Rakuten, threatening network quality, customer losses, and costly catch-up spending. This is a significant blow to Rakuten's mobile business.
This is a major negative event that could hurt future earnings and competitiveness.
Government satellite funding and AST partnership Japan granted up to ¥148bn for a domestic satellite network, reducing reliance on foreign services. A joint venture with AST SpaceMobile targets satellite-powered mobile service next year, adding a growth driver.
This new funding and partnership open a new growth avenue and reduce dependency risks.
Warehouse writedown and regulatory friction A ¥17bn warehouse writedown pushed a quarterly net loss of ¥10.9bn. Regulatory friction also rose: scrutiny over furusato nozei fees and a forced reversal of its Rakuten ID contract policy.
These negative items add financial and regulatory pressure, weighing on sentiment.

Rakuten's mobile network loses KDDI roaming as new bets and setbacks mix

KDDI roaming ends, network quality at risk KDDI is ending the roaming deal that let Rakuten Mobile borrow its network in cities from October. Rakuten's own 5G base stations lag rivals and its 2025 buildout fell far short of plan, so quality may drop, customers may leave, and catching up could mean costly new spending that revives losses.
This is the biggest force on Rakuten's mobile unit, threatening subscribers and profitability.
17 billion yen warehouse writedown deepens loss Rakuten wrote down 17 billion yen of warehouse leasing assets to zero and will use the space itself, pushing its second-quarter net result to a 10.9 billion yen loss. That is a direct hit to reported profit and shows the logistics side is not yet paying off.
A concrete capital loss that directly reduces reported earnings and investor confidence.
Regulatory pushback on fees and ID policy Rakuten kept its furusato nozei fee while three rivals agreed to cut, drawing ministry scrutiny. Days later it scrapped a plan to auto-cancel mobile contracts without a Rakuten ID after the communications ministry intervened. Both show regulatory friction that can raise costs and hurt its public standing.
Regulatory pressure on two key businesses is a real counterweight to the growth story.
New defense drone and Ferrari partnerships Rakuten will act as Japanese go-between for German drone maker Helsing's defense drones, a new revenue path beyond its inspection drone work. It also signed a global partnership with Ferrari starting 2027, extending the sports-sponsorship brand strategy. Both are early-stage and financial details are undisclosed.
These are the period's main positive developments, showing new business and brand expansion.

Rakuten's satellite bet and first profit in seven years drive the story

Government grant for satellite network Japan will give Rakuten up to 148 billion yen to build a domestic satellite communications network, reducing reliance on foreign services like Starlink. This is a huge cash injection that lowers the cost and risk of a new growth business, supporting the share price.
This is a major new capital boost that directly improves Rakuten's financial position and future prospects.
Joint venture with AST SpaceMobile Rakuten is forming a joint venture with AST SpaceMobile to offer satellite-powered mobile service in Japan, with coverage targeted for next year. This opens a new revenue stream and strengthens Rakuten Mobile's offering, which the market views as a positive growth driver.
The JV is a concrete new business expansion that could add subscribers and revenue, directly impacting Rakuten's value.
First operating profit in seven years Rakuten reported a 50.4 billion yen operating profit for the June 2026 interim period, its first in seven years, as internet shopping and financial services grew strongly and mobile losses narrowed. This shows the core business is turning around, a key positive for the stock.
Profitability is the most fundamental driver of share price, and this milestone signals a major improvement in Rakuten's financial health.
Mobile service disruptions after Kumamoto earthquake Rakuten Mobile's services were disrupted in Kumamoto after a powerful earthquake, with no timeline for restoration. While temporary, this highlights network vulnerability and could hurt customer trust and add costs, a modest negative for the stock.
This is a new operational setback that could affect Rakuten Mobile's reputation and near-term performance.
