The letter of intent is a central component of the mergers & acquisitions (M&A) process. It is a joint declaration of intent that is signed by the parties involved and guides the negotiations on a company purchase in an orderly manner. Although the LOI is usually not legally binding, it plays a decisive role in creating a solid basis for the further procedure, in particular the due diligence process. This article sheds light on the importance of an LOI and looks at the key content that should be included in such a document.
The LOI in the M&A process and differences to the NBO and term sheet
In a structured M&A process, the seller approaches various potential buyers, usually via a specialised M&A advisor. If there is interest, extensive documentation is made available, initial discussions are held between the parties and the most important questions of the potential buyer are answered. In some cases, limited access to a data room is granted.
On this basis, non-binding offers (NBOs or non-binding offers) are requested from the interested parties. An NBO is a unilateral expression of interest in which the buyer summarises the valuation and important assumptions of their offer. The seller can now form an impression of the offers and – depending on the competition – continue the process with a selection of interested parties.
Then a more in-depth (so-called confirmatory) due diligence begins: the buyer will begin an intensive examination of the company, typically with the involvement of external experts. However, a potential buyer will often require the conclusion of an LOI before going deeper into due diligence or contract negotiations. One important reason for this is that, depending on the size and complexity of the company, relatively high costs are incurred that the buyer wants to secure. In venture capital financing, the term ‘term sheet’ tends to be used in the process. There is no clear distinction between this and the LOI, but the term sheet is typically more concise and focusses more on commercial points and governance issues.
