Paris, 17 September 2026 – As at 30 June 2026, Net Asset Value (NAV) per share stood at €33.95, up 5.0% versus 31 December 2025 (€32.32 per share).

1. PERFORMANCE

NAV (IFRS shareholders' equity) stood at €1,239.5m (versus €1,179.9m at 31 December 2025). The change over the half-year is explained by the following items:

Including a positive foreign-exchange effect of €7.6m, total value creation reached €68.1m over the half-year, of which €66.5m was unrealised value creation. This growth reflects the strong operating performance across the whole portfolio, with a positive contribution from each of the four sectors. Services was the largest contributor to value creation (€21.9m), driven notably by HRK Lunis, Veriforce and Infraneo, followed by Tech (€20.2m), driven notably by Odin, ThoughtWorks, Hirsch and Teciem.

2. ACTIVITY

a) €15.3m of total and partial disposal proceeds received over the half-year (versus €79.7m in H1 2025):

Partial disposal proceeds and income received during the half-year mainly comprise dividends paid by OnCourse Home Solutions (€7.1m) and Authority Brands (€1m). They also include €2m of disposal proceeds from funds, mainly from the Apax Digital fund (€1.8m).

b) €37.3m invested and committed over the half-year (versus €93.5m in H1 2025):

• €29.2m invested and committed via the Apax XI LP fund in 3 companies:

• Sedex (€14.5m committed, transaction not completed as at 30 June): founded in 2004 by a consortium of major British retailers (including Marks & Spencer, Sainsbury's and Tesco), Sedex has become the world's leading supply-chain risk management platform, specialising in social compliance. It enables large companies to verify that their suppliers comply with labour rights, safety conditions and ethical standards at their production sites. Across 180 countries, Sedex connects more than 100,000 buyers and suppliers around SMETA, one of the most widely recognised social-audit standard worldwide.
• Yad2 (€11.0m invested): founded in 2001 in Tel Aviv, Yad2 is Israel's leading classifieds platform, covering real estate and automotive (around 80% of revenue) as well as employment. Its model relies mainly on professionals (agents, dealers, etc.) who pay subscriptions to post listings and generate leads, while access is largely free for individuals.
• Id Fresh Food (€3.7m invested): founded in 2005 in Bengaluru, iD Fresh Food is India's leading fresh, ready-to-cook food company, free of preservatives and prepared using traditional methods. Present in more than 50 cities across India and the Gulf region, it employs close to 2,400 people and holds an estimated 50–60% market share in its key segments (idli/dosa batter and Indian breads).

In addition, a negative adjustment of €9.5m was recorded to reflect the final amounts invested via the Apax Seven2 MidMarketX fund in Zwart Techniek and via the Apax XI LP fund in Teciem.

• €10.9m invested via funds, mainly via the Altaroc Odyssey funds,
• Lastly, €6.7m of follow-on investments were made within the existing portfolio, mainly via the Seven2 MidMarket X fund to finance acquisitions made by Infraneo (€2.0m) and Odin (€2.0m).

3. CASH AND COMMITMENTS

As at 30 June 2026, the Company's statutory accounts show net cash of -€71.9m (versus -€56.7m at 31 December 2025 and -€72.3m at 31 March 2026), reflecting the low level of disposals in recent months.

Against this backdrop, while near-term liquidity remains constrained, the Company has a significant portfolio of assets and several sources of liquidity. In addition to the disposals already announced, Seven2 and Apax are expected to complete liquidity transactions by year-end, while Altamir is concurrently working on additional transactions. Together, these measures will enable the Company to preserve its financial flexibility and its ability to seize new investment opportunities through the end of the financial year.

As at 30 June 2026, Altamir's maximum commitments stood at €287.5m (of which €55.9m committed but not yet called), plus €114.6m of distributions that may be recalled.

These commitments break down as follows:

• For funds in their investment period: €306.9m (of which 8% are distributions that may be recalled), mainly €147.2m in the Apax XI LP fund, €71.7m in the Seven2 MidMarket X fund and €59.0m in the Altaroc Odyssey funds;
• For funds in their divestment period: €95.2m (of which 95% are distributions that may be recalled), mainly €55.3m of distributions that may be recalled by the Apax X LP fund, €14.0m by the Apax MidMarket VIII fund and €10.6m by the Apax IX LP fund.

4. KEY EVENTS SINCE 30 JUNE 2026

Apax announced the acquisition, via two separate transactions, of techoraco and Institutional Investor: techoraco is the leading global events platform for the digital infrastructure sector, and Institutional Investor is a leading platform connecting institutional investors. Apax intends to bring the two companies together within the same events portfolio without merging them, with the ambition of eventually adding other complementary brands.

Apax also announced the acquisition from the Gerresheimer group of Centor and Primary Packaging Plastics, two leading companies in pharmaceutical packaging and prescription-drug bottles. Together they operate 16 production sites in nine countries, employ around 2,400 people and generated combined revenue of approximately €570 million in 2025.

Apax Digital II announced two investments.

Lastly, Apax announced the full disposals of Tosca and Oncourse Home Solutions, held via the Apax IX LP fund and the Apax X LP fund respectively.

Altamir's IFRS financial statements for the half-year ended 30 June 2026 were approved by the Board of Directors of Altamir Gérance on 15 September 2026. They were subject to a limited review by the statutory auditors.
