The curtain has fallen on the 2026 interim reporting season, revealing a sharply divided picture for the mobility sector in Hong Kong. Caocao Travel (02643.HK) has secured its position as the industry leader by surpassing the 10 billion yuan revenue threshold for the first time in a half-year period, while OnTime Travel (09680.HK) is rapidly closing the gap with an impressive 140.7% revenue surge and significantly narrowed losses. In stark contrast, Dida Chuxing (02559.HK) has encountered severe headwinds, experiencing a 42.3% revenue plunge and a swing into losses, culminating in its acquisition by Tongcheng Travel just a week before its results were announced - making it the inaugural casualty among independent players in this arena.

Beyond these three listed entities, T3 Travel submitted its listing application in April 2026, and Xiangdao Travel filed for a second time in May. However, investor enthusiasm for the mobility sector has waned considerably; Caocao Travel's market capitalization stands around HK$7.9 billion, down approximately 66% from its IPO price, while OnTime Travel's valuation has dwindled to a mere HK$1.4 billion with a price-to-sales ratio of only 0.16 times. With the formidable shadow of industry behemoth Didi looming large, the path to a successful public listing for these challengers is fraught with difficulty.

Caocao Travel: Revenue Milestone Overshadowed by Persistent Losses and Sinking Valuation

Caocao Travel generated total revenue of 10.34 billion yuan in the first half, a 9.0% year-on-year increase, achieving a historic milestone by exceeding the 10 billion yuan mark for a six-month period. Revenue from mobility services reached 9.792 billion yuan, up 13.9%, representing 94.7% of its total turnover. The average monthly active users (MAUs) expanded by 17.1% to 44.6 million, while average monthly active drivers grew by 36.8% to 758,000. The company's coverage has extended to 215 cities. Gross transaction value (GTV) hit 12.445 billion yuan, reflecting a 13.6% year-on-year increase. Gross profit for the period was 928 million yuan, translating to a gross margin of 9.0%, a slight improvement from 8.7% in the corresponding period last year.

However, the nagging issue of "rising revenue without corresponding profit growth" persists. The company reported a loss of 380 million yuan for the half-year, a 17.5% narrowing from the previous year, with an adjusted net loss of 307 million yuan, bringing the loss margin down to 3.0%. Vehicle sales revenue plummeted by 60.3% to 295 million yuan from 744 million yuan a year earlier. Net cash generated from operating activities contracted sharply to 65.99 million yuan, an 80.5% decrease from the 338 million yuan recorded in the first half of last year. The company's cash and cash equivalents stood at 1.563 billion yuan, a clear decline from 2.325 billion yuan in the prior year.

Adding to the concern is the inconsistency in profitability. After achieving a first-ever positive adjusted net profit in the fourth quarter of 2025, Caocao Travel slipped back into a net loss of 230 million yuan attributable to shareholders in the first quarter of 2026. During the earnings call, management provided a cautious profitability timeline, stating that they "hope to achieve a turnaround to profitability within fiscal years 2026 to 2027." The share price performance has been equally disheartening. As of September 3, the stock closed at HK$13.61, giving a market capitalization of approximately HK$7.906 billion. Based on an annualized revenue of around 20 billion yuan from the interim results, its price-to-sales ratio is a meager 0.4 times, reflecting a market that has shifted its valuation logic from "growth story" to "profitability proof."

In search of new avenues, Caocao Travel has pivoted its strategy towards "AI + Robotaxi." The company unveiled its RoboX strategy in June 2026, having deployed 140 second-generation Robotaxis by the end of the reporting period, with third-generation L4 custom vehicles, "Eva Cab", slated for mass production in 2027. It has also formed a joint venture with Octopus to push into international markets, starting with Hong Kong, and has integrated with the Doubao AI ecosystem, with AI-enabled ride-hailing features currently in grey-scale trials. However, these initiatives are unlikely to contribute meaningful profits in the near term.

OnTime Travel: Fastest Growth, Yet Most Severe Market Value Erosion

OnTime Travel stands out as the fastest-growing entity among the three listed companies. Its first-half revenue surged 140.7% year-on-year to 4.035 billion yuan, with gross margin improving to 12.4% from 11.7% in the same period last year. The company's loss narrowed by 45.2% to 68.498 million yuan for the period. In its mobility services segment, transaction volume reached 5.064 billion yuan with 184 million orders, translating to 1.0152 million daily orders. Its technology services segment posted a profit of 20.305 million yuan, a substantial leap from 893,000 yuan in the prior year, highlighting the emergence of AI-driven technology services as a promising second growth curve.

Despite this impressive growth, OnTime Travel's market valuation has fallen to startlingly low levels. As of September 3, the stock was trading at HK$7.06, giving it a market cap of merely HK$1.441 billion over two years post-IPO. Even with an annualized revenue of roughly 8 billion yuan based on interim figures, its price-to-sales ratio sits at a thin 0.16 times. This indicates that despite being the fastest grower, the market is unwilling to grant a higher valuation. This valuation collapse underscores a deep-seated skepticism about the earnings prospects within the mobility sector. Even though OnTime Travel is rapidly reducing its losses, the path to genuine profitability remains elusive, and investor patience for second-tier platforms is wearing thin.

Dida Chuxing: A 40% Revenue Collapse and Acquisition Two Years After Listing

Among the trio, the story of Dida Chuxing is the most sobering. First-half revenue fell by a sharp 42.3% to just 165 million yuan, swinging to a net loss of 62.31 million yuan against a net profit of 134 million yuan in the same period last year. The adjusted net loss stood at 56.9 million yuan, compared to an adjusted net profit of 129 million yuan previously. Revenue from travel-related services was 160 million yuan, while advertising and other services contributed 4.89 million yuan. This decline was not sudden; revenue for Dida slid from 815 million yuan in 2023 to 787 million yuan in 2024 and further down to 502 million yuan in 2025, marking three consecutive years of contraction. The total number of ride-pooling orders plummeted from 119 million in 2024 to 76.5 million, and the transaction scale shrank from 7.4 billion yuan to 4.5 billion yuan. The ride-pooling model faces regulatory constraints on daily order limits, capping supply capacity, while behemoths like Didi continue to penetrate the segment, drawing both passengers and drivers away with low-priced options and eroding Dida's competitive pricing advantage.

Dida Chuxing listed on June 28, 2024, earning the crown of being the "first share in shared mobility," but its shares broke below the IPO price on day one, setting for a long decline. On June 29, 2026, Tongcheng Travel (00780.HK) initiated a voluntary conditional cash offer through its wholly-owned subsidiary at a price of HK$1.3875 per share. By August 21, 2026, with valid acceptances for 911 million shares representing approximately 88.74% of Dida's issued share capital, the acquisition was completed. Post-acquisition, Dida will maintain its brand and operational independence, and Tongcheng plans to preserve its Hong Kong listing status. From listing to being acquired took just over two years. As of September 3, Dida's market value was about HK$1.057 billion, less than one-sixth of its approximate HK$6.1 billion valuation at IPO. While the stock price surged after the acquisition news, it signified the end of the road for the standalone ride-pooling business model. Tongcheng Travel's interest lies in the synergy between Dida's mobility services and its tourism ecosystem, as its 250 million annual paying users seeking flights and hotels will require ground transportation solutions. For Dida, though, this marked its denouement as an independent entity.

The Challengers: T3's Paper-Thin Profit and Xiangdao's Second Filing Attempt

T3 Travel officially filed its listing application with the Hong Kong Stock Exchange on April 22, 2026. In 2025, it posted revenue of 17.109 billion yuan with a net profit of just 7.44 million yuan, claiming to be "the large intelligent mobility platform in China to achieve profitability the fastest." Yet, this 7.44 million yuan profit against 17.1 billion yuan in revenue translates to a razor-thin net margin of 0.04%. While improvements are underway - its ride-hailing service gross margin jumped from -0.5% in 2023 to 12.3% in 2025 - the quality of this "accounting-driven turnaround" warrants scrutiny. Notably, approximately 86% of its orders rely on its shareholders and related parties, casting doubt on its independence post-listing and its reliance on such "life-support growth." Furthermore, its R&D expense ratio is only about 1%, raising questions about its ability to sustain an "AI + Mobility" narrative in an era where competitors are making heavy investment commitments.

Xiangdao Travel made its second listing attempt on May 22, 2026. Its initial filing lapsed on April 28, 2026, due to the expiry of the six-month review period. In 2025, the company generated 6.774 billion yuan in revenue but incurred a net loss of 246 million yuan, with a gross margin of 10.98%. Founded by automotive giant SAIC Motor, it has attracted industry investors such as Momenta, Amap, and CATL. Its cumulative losses over three years exceed 1.2 billion yuan. Backing from SAIC provides Xiangdao with advantages - vehicle supply, manufacturing capability, and industrial chain synergies - but also limits. Over-reliance on a single shareholder's resources could pose challenges for independent growth and market competition. In the Robotaxi domain, Xiangdao plans to achieve scaled commercial operations in multiple cities by 2027, a timeline nearly identical to Caocao Travel's "Eva Cab" mass production target. But the critical question remains: how much longer will capital markets be patient?

The Didi Shadow, Robotaxi Bubble Concerns, and Listing Hurdles

The fundamental issue plaguing the mobility sector is the sheer scale of Didi. In the first half of 2026, Didi generated revenue of 121.265 billion yuan, up 10.58% year-on-year. Its operating profit turned to 363 million yuan from a 1.389 billion yuan loss a year earlier. In the second quarter alone, its net profit attributable to shareholders was 866 million yuan, with its China mobility business reaching a record 40.1 million daily orders. Combined, the revenue of Caocao Travel, OnTime Travel, Dida Chuxing, T3 Travel, and Xiangdao Travel totals approximately 38.4 billion yuan, which is merely 30% of Didi's first-half revenue. This disparity is magnified in the capital markets as a valuation chasm, with Didi's market cap around US$15.686 billion (approximately HK$122 billion) dwarfing the combined HK$10.4 billion of the three listed challengers, who together hold less than one-tenth of Didi's value.

This extreme valuation divergence reflects a market consensus that Didi's dominance as an industry leader is virtually insurmountable. Its first-mover advantages, network effects, and capital heft have created a formidable moat that competitors, regardless of their growth rate or narrowing losses, find difficult to breach in terms of obtaining a reasonable valuation premium. Beyond the valuation quandary, players in this sector are also making a collective bet on a rather nascent future. Caocao Travel, OnTime Travel, T3, and Xiangdao all feature Robotaxi as a central keyword in their prospectuses and financial reports. Caocao has deployed 140 second-generation Robotaxis and plans mass production of its third generation by 2027; OnTime is pushing forward with Robotaxi pilot operations; T3 has integrated over 300 Robotaxis and completed over 41,000 kilometers of driverless road tests; and Xiangdao aims for multi-city scaled commercial operations by 2027.

However, the commercialization of Robotaxi is far more complex than anticipated. Every link - technological maturity, policy regulations, cost structures, and user acceptance - harbors significant uncertainties. Until scaled commercial operations are achieved, Robotaxi remains a capital-intensive narrative rather than a profit-generating business. More critically, even if Robotaxi does become a reality, Didi is still the most likely winner. With its extensive mobility data, superior algorithmic capabilities, and vast user and driver network, if Robotaxi represents the endgame for the mobility industry, Didi's advantage in that final scenario is poised to be larger, not smaller, than it is today.
