Serbian businessman Davor Macura is moving closer to transforming Alta Group from a fast-growing domestic financial company into a regional banking platform spanning Serbia, Bosnia and Herzegovina, Montenegro and North Macedonia.
The expansion would result from the proposed acquisition of four Addiko subsidiaries: Addiko Bank Serbia, Addiko Bank Montenegro, Addiko Bank Sarajevo and Addiko Bank Banja Luka. The transaction is part of a wider takeover of Vienna-listed Addiko Bank AG by Raiffeisen Bank International, rather than a direct purchase of the entire Addiko group by Alta.
The distinction is important. Alta has not yet completed the acquisition, and the transaction remains subject to the successful closing of RBI’s takeover, separation of the four subsidiaries from Addiko’s Austrian parent and approvals from banking and competition regulators in the affected markets. RBI previously indicated that its acquisition of Addiko was expected to close in the fourth quarter of 2026, while the subsequent carve-out and transfer to Alta could be completed during the second half of 2027.
RBI crossed the minimum acceptance threshold for its takeover offer at the end of July. Shareholders tendered 10.83 million Addiko shares, equivalent to 56.16 per cent of the shares covered by the offer, slightly above the revised threshold of more than 55 per cent. Alta contributed its directly owned 1.88 million shares, representing 9.63 per cent of Addiko’s issued capital, to RBI’s offer. Raiffeisen Bank International
The structure creates a two-stage transaction. RBI would first acquire control of the Vienna-based Addiko group. It would retain Addiko’s operations in Austria, Croatia and Slovenia, strengthening its Croatian position and restoring a direct banking presence in Slovenia. Addiko’s businesses in the three non-EU Western Balkan markets would then be separated and sold to Alta at no less than fair market value.
This division reflects different strategic priorities. RBI is concentrating on larger EU-regulated banking markets where it can combine Addiko with its existing regional infrastructure or use the acquisition to reopen a strategically relevant market. Alta is receiving the part of the network that offers a more natural geographic fit with its Serbian base, its payment-services platform and its existing banking operation in North Macedonia.
The agreed purchase price for the four subsidiaries has not been disclosed. This means the transaction cannot yet be assessed through a conventional acquisition multiple such as price-to-book value or price-to-earnings. The “fair market value” requirement protects RBI against selling the businesses to its transaction partner at an artificially low price, while preserving scope for valuation adjustments based on capital, loan quality, profitability and the cost of separating the subsidiaries from Addiko’s central systems.
The carve-out is commercially more complex than a straightforward share transfer. Addiko currently operates with shared technology, risk management, treasury, compliance, branding and reporting structures across Central and Southeast Europe. The Serbian, Montenegrin and Bosnian banks will need operational arrangements that allow them to function independently from the Austrian parent before they can be integrated into Alta.
Technology migration will be one of the largest execution risks. Core banking systems, digital applications, data storage, cybersecurity controls, anti-money-laundering monitoring, regulatory reporting and payment infrastructure cannot be transferred without extensive testing. Transitional-service agreements with Addiko or RBI may be required until Alta establishes or expands its own regional platform.
The regulatory process will be equally demanding. Alta will need to demonstrate that it has sufficient capital, transparent financing, appropriate governance and robust risk controls to own and manage four additional banks. Separate approvals will be required because Bosnia and Herzegovina has two banking jurisdictions: Addiko Bank Sarajevo is supervised within the Federation of Bosnia and Herzegovina, while Addiko Bank Banja Luka operates under the regulatory framework of Republika Srpska.
Approvals will also be required from the National Bank of Serbia and the Central Bank of Montenegro, alongside competition clearances and the wider European approvals needed for RBI’s takeover of Addiko Bank AG. Until these conditions are satisfied, the transaction should be treated as an agreed strategic pathway rather than a completed transfer of ownership.
In Serbia, the acquisition would materially enlarge Alta Bank but would not place it among the country’s largest lenders. At the end of 2025, Alta Bank had assets of approximately RSD194.1 billion, representing around 2.77 per cent of the Serbian banking market. Addiko Bank Serbia had assets of RSD103.8 billion and a market share of approximately 1.48 per cent.
A simple combination of the two balance sheets would therefore create a bank with close to RSD298 billion, or approximately €2.5 billion, in assets and a market share of around 4.25 per cent, before acquisition accounting, portfolio changes or balance-sheet growth. That would give Alta greater scale and move it further into Serbia’s mid-sized banking tier, but the combined institution would remain well behind the dominant foreign-owned banks.
Profitability makes the Serbian subsidiary commercially attractive. Addiko Bank Serbia generated net profit of approximately RSD1.86 billion in 2025, an increase of 72 per cent, despite a 4 per cent decline in total assets. Customer loans grew by about 10 per cent to RSD69 billion, while lending to households and small and medium-sized companies accounted for 93 per cent of the loan portfolio.
Alta Bank reported 2025 profit of approximately RSD1.37 billion. On an unadjusted basis, the two banks produced combined earnings of more than RSD3.2 billion, although this cannot be treated as a forecast for the merged operation. Financing costs, integration expenditure, restructuring, technology investment and possible portfolio harmonisation could initially reduce reported profitability.
The strategic fit lies in the different characteristics of the two businesses. Alta has developed a broader financial-services ecosystem encompassing banking, payments, leasing, foreign-exchange operations and a large physical payment network. Addiko is a specialist consumer and SME lender with an established digital platform, unsecured cash-loan expertise and a relatively focused credit portfolio.
Alta’s payment network gives the group a distribution channel beyond conventional bank branches. Addiko contributes consumer-credit analytics, an identifiable retail franchise and a portfolio concentrated on households and SMEs. A successful combination could allow Alta to distribute bank accounts, cards and loan products through a wider network while applying Addiko’s underwriting and digital-sales capabilities.
The commercial logic is stronger than a simple attempt to accumulate bank assets. Serbia’s banking sector is already highly consolidated, profitable and dominated by well-capitalised international groups. A mid-sized domestic challenger cannot compete with larger banks merely by expanding its branch network. It needs lower acquisition costs, faster digital lending, specialised SME products and an integrated payment infrastructure capable of generating fee income.
The Addiko acquisition could provide those capabilities, but integration decisions will determine whether the expected value is realised. Alta must decide whether Addiko Bank Serbia will be merged into Alta Bank, retained as a separate legal entity for a transitional period or operated under a differentiated brand. A merger could eliminate duplicated functions and improve capital efficiency, while a two-brand structure could preserve Addiko’s consumer recognition and reduce immediate migration risk.
Bosnia and Herzegovina gives Alta a substantially larger regional footprint. The two Addiko banks operate as legally and operationally separate institutions. Addiko Bank Sarajevo ended 2025 with assets of approximately BAM1.28 billion, equivalent to around €652 million, and net profit of BAM21.7 million, or roughly €11.1 million. Its market share by assets was approximately 3.6 per cent at the national level.
Addiko Bank Banja Luka provides a complementary position in Republika Srpska. Together, the two institutions give Alta coverage across the principal Bosnian banking jurisdictions without requiring it to establish a new operation, obtain a banking licence from the beginning or build a customer and deposit base organically.
Bosnia’s fragmented banking market offers consolidation opportunities but also limits immediate integration benefits. Separate regulatory regimes, legal entities, reporting requirements and deposit-protection arrangements mean that Alta cannot operate the two banks as though they were a single Serbian-style subsidiary. Central functions can be aligned, but each bank will continue to require locally compliant governance, capital and liquidity management.
In Montenegro, the acquisition of Addiko Bank Podgorica would connect Alta’s banking operations with a market where the group already has experience through payments and foreign-exchange services. Addiko’s Montenegrin market share is relatively modest, estimated at around 2.5 per cent of banking assets, but the subsidiary provides a licensed platform in a euroised economy with strong links to tourism, real estate, consumer finance and cross-border business.
The Montenegrin operation could carry strategic value beyond its present balance-sheet size. Euro-denominated deposits and loans remove local currency-conversion risk, while Montenegro’s EU accession process is expected to increase regulatory convergence and cross-border investment. The bank could serve Serbian corporate clients investing in Montenegro, Montenegrin businesses trading with Serbia and international investors requiring a banking relationship across both markets.
Alta’s regional map would then comprise its existing businesses in Serbia and North Macedonia, plus new banking operations in Montenegro and both entities of Bosnia and Herzegovina. This is not yet a fully integrated Southeast European banking group, but it represents the infrastructure from which one could be built.
The financing structure will be closely watched. Alta is exchanging a liquid listed shareholding in Addiko Bank AG for the opportunity to acquire privately held banking subsidiaries. Its directly owned 9.63 per cent stake would be sold into RBI’s cash offer at €26.50 per share, producing gross proceeds of approximately €49.8 million for those shares. Alta had also disclosed financial instruments linked to an additional 19.96 per cent of Addiko’s share capital, although the final economic outcome of those positions depends on their contractual terms.
The cash received from the tendered shares may contribute to financing the carve-out, but it is unlikely by itself to cover the fair-market value of four profitable banks. Alta may need a mixture of its own capital, shareholder funding, subordinated instruments, external borrowing or retained earnings. Regulators will examine whether the financing structure leaves sufficient capital within each acquired bank after completion.
This is particularly important because acquisition growth can weaken capital ratios when the buyer pays above book value, recognises goodwill or incurs significant restructuring costs. RBI itself estimated that acquiring Addiko would initially reduce its core equity tier-one ratio by approximately 46 basis points, but that the effect would fall to around 11 basis points after selling the four carve-out subsidiaries. The sharp reduction demonstrates that disposal of the Western Balkan operations is central to RBI’s capital logic, not a peripheral part of the deal.
The transaction also illustrates a wider change in Balkan banking. During the previous two decades, consolidation was largely driven by Austrian, Italian, French, Greek and Slovenian institutions purchasing local banks. The Addiko carve-out reverses part of that pattern by placing a Serbian-controlled financial group in a position to acquire regulated banks from an Austrian parent across several neighbouring markets.
Alta will nevertheless inherit the obligations normally associated with international banking ownership. Expansion creates greater scrutiny of anti-money-laundering controls, related-party exposure, sanctions compliance, cybersecurity, consumer protection and the consistency of group-wide governance. A payment-services company can expand rapidly through commercial networks; a cross-border banking group must demonstrate that control functions grow at the same pace as its balance sheet.
The transaction’s value will ultimately depend on whether Alta can convert geographic expansion into a coherent operating platform. Four additional banking licences and several hundred thousand potential customers create scale, but scale alone does not guarantee higher returns. The commercial gain lies in common digital infrastructure, centralised product development, efficient funding, disciplined credit underwriting and cross-border services for consumers and SMEs.
RBI’s successful offer has opened the route, but ownership has not yet changed. The decisive phase will come during the regulatory reviews, financing process and operational separation scheduled to extend into 2027. Completion would give Alta assets and licences across four Western Balkan markets, turning the group into the most ambitious Serbian-led banking expansion since the region’s post-transition consolidation cycle.
