MTR Corp. signed the second and final project agreement for the Northern Link with the Hong Kong government on Tuesday, committing the city's rail operator to finance, build and run a line that it puts at around HK$90 billion in July 2025 prices, according to a stock exchange filing published that evening.

For investors, the deal fixes the terms of one of MTR's biggest commitments. The company will pay the full cost of the second stage, including land acquisition, and has laid out a capital spending ramp that rises more than fivefold between 2027 and 2029. In return it keeps the rail-plus-property model that has funded Hong Kong's network for decades, with development rights at eight sites in the Northern Metropolis, the government's planned growth zone along the Shenzhen border.

What MTR has agreed to pay

The Part 2 agreement covers construction of the rest of the Northern Link main line, between Kam Sheung Road and Kwu Tung, and the cross-boundary spur line from San Tin to a new Huanggang Port station in Shenzhen. It also hands MTR the operation and maintenance of both as one railway. The scheduled operating date is no later than Dec. 31, 2034, the filing said.

MTR said it expects to spend the Part 2 cost over about 10 years, with capital expenditure of about HK$1.1 billion in 2027, HK$2.9 billion in 2028 and HK$5.9 billion in 2029.

The first agreement, signed in July 2025, put the Part 1 cost at about HK$31.40 billion, also in July 2025 prices, according to MTR's filing at the time. Taken together with the new filing's combined estimate, that leaves roughly HK$58.6 billion for the second stage, a Capital Times calculation.

The company acknowledged the scale of the bill, "not least in combination with the other investment and growth plans already underway." It said it had studied financeability with external advisers and concluded the spending could fit within its funding plans, citing its cash holdings, access to capital markets and the 10-year spread of the outlays. Rothschild & Co Hong Kong advised the board that the agreement was on normal commercial terms and fair to shareholders, the filing said. Directors appointed by or holding posts in the government did not take part in the board discussion.

If commercial operation starts after the scheduled date, MTR must set aside part of its railway revenue to fund network improvements. That mechanism replaces a similar penalty in the Part 1 agreement.

Northern Link property rights and land premium

The financial return rests on land. MTR may develop about 46 hectares across eight sites at Kwu Tung North, Ngau Tam Mei, San Tin and Au Tau for residential, commercial and railway use, subject to approval by the Chief Executive in Council and, where needed, the Town Planning Board, and to the government completing land resumption.

The company will pay land premium at full market value, minus a fixed reduction amount of HK$86.43 billion split into tranches by site. That comes on top of a HK$39.05 billion reduction amount and about 26 hectares across 10 sites granted under the Part 1 agreement. Where premium is still owed after the deduction, MTR can defer it, with interest, to later sites in either stage, and must settle any balance after the last site is assessed.

MTR cautioned that the property income is not guaranteed. The contribution, it said, depends on the future property market, building costs and the floor area finally approved, and there is no assurance the developments will deliver a commercial rate of return. Recent data showed resale prices slipping even as new supply climbs, which bears directly on how much value the Northern Metropolis sites can generate when they come to tender.

Shenzhen section and timetable

Part of the spur line will run inside Shenzhen. The Hong Kong and Shenzhen governments are expected to sign a separate agreement on that section, and MTR will need its own agreements with the Shenzhen Municipal People's Government to build and operate it. MTR said it signed on the basis of its understanding of the proposed arrangements and expects the Hong Kong government to keep supporting the negotiations.

Raymond Ip Wai-man, the Commissioner for Northern Metropolis Railways, said in a radio interview that building the main and spur lines at the same time would bring completion forward by about two years, The Standard reported. He said review times for building plans had been cut by 30% to 50% through a dedicated checking unit and an electronic platform, and that oversight standards were unchanged, according to the newspaper. The Standard cited a construction budget of HK$86.2 billion, which it described as 28% below initial estimates; MTR's filing gives the combined figure of around HK$90 billion.

MTR said the Northern Link will join the East Rail Line and the Tuen Ma Line, both of which it operates, into a loop linking the New Territories with urban Kowloon. The filing also said the company may adopt the Hong Kong Railway Standards introduced in February 2026 and use system-wide contracting across the whole project to hold costs.

The agreement was signed on a day when Hong Kong stocks rose. The Hang Seng Index gained 0.44% to 24,557 on Tuesday, led by financials, The Standard reported.

The next markers for shareholders are the government-to-government agreement on the Shenzhen section and the first Northern Link site tenders, where the size of each premium deduction will show how much of the HK$86.43 billion MTR can put to use.
