The beneficiaries identified in the provided context are as follows:

1. Small and medium-sized enterprises (SMEs) and households, particularly those previously bound to local energy suppliers in basic electricity supply, can benefit from increased competition leading to price pressure and more diverse offers. Especially those willing to switch suppliers and households in currently expensive supply areas stand to gain. Large customers above 50 MWh can protect themselves against market price fluctuations through structured procurement[1].

2. Swiss agricultural and food producers benefit from easier participation in the EU internal market due to the reduction of non-tariff trade barriers, which strengthens their competitiveness. Additionally, both Swiss and EU producers benefit from aligned regulations, avoiding adjustments in packaging or recipes when marketing products in both markets[2][3].

3. Researchers, SMEs, and start-ups gain advantages through association with EU framework programs, enabling access to increased competition for funding, enhanced reputation, greater visibility, networking opportunities, and the ability to attract excellent researchers (brain-gain effect). This association also supports additional public and private funding leverage[4].

4. Swiss companies benefit indirectly and directly from the Swiss contribution to partner countries by gaining increased visibility, building closer economic relations, and accessing new markets and investment opportunities. Moreover, Swiss companies can profit from public contracts funded by EU structural and cohesion programs[5][6].

In summary, those who benefit include SMEs, households (especially price-sensitive and willing to switch), agricultural and food producers, researchers, start-ups, and Swiss companies engaged in economic relations with the EU and partner countries.
