Joint ventures allow companies to share financial risk and resources to undertake new business ventures. They provide access to new markets and expertise while reducing costs through resource sharing. Notable Indian joint ventures include Maruti Suzuki, Sony India, and Bharti Walmart. Acquisitions involve one company purchasing another to gain control of its assets and operations. Mergers combine two companies into a new entity with mutual agreement between partners. Franchising is a business model where franchisees operate under an established brand in exchange for fees. Exit strategies like sale, IPO, or liquidation allow business owners to realize returns and transition out of their investment.
