Amprion enhances its financial strength: issuance of a green bond and increase in the syndicated loan agreement

•    Successful issuance of a green dual-tranche bond worth €1.5 billion
•    Expected ratings for the bond are Baa1 from Moody's and A- from Fitch
•    Proceeds will be used exclusively to finance Amprion's green project portfolio for implementing the energy transition in Germany
•    Syndicated loan agreement increased by €600 million to €3.2 billion

Transmission system operator Amprion GmbH (“Amprion”) has successfully issued a green dual-tranche bond for the second time this year. The total volume of the bond is €1.5 billion. Amprion regularly issues green bonds to finance its green project portfolio, thereby making a significant contribution to the implementation of the energy transition in Germany.

The bond was issued in two tranches and is listed on the Euro MTF market of the Luxembourg Stock Exchange:

•    The first tranche, with a volume of €600 million, has a term of 4 years and an interest coupon of 2.750% p.a.
•    The second tranche, with a volume of €900 million, has a term of 15 years and an interest coupon of 4.000% p.a.

The bond was issued as part of Amprion's debt issuance programme, which now totals €25 billion and met with considerable interest from investors.

In addition, Amprion has increased the Group's syndicated loan agreement by €600 million to a total of €3.2 billion. This further strengthens the company's financial position in the area of short-term financing.

"We are delighted with the successful issuance of this bond and the further increase in the syndicated loan agreement. Good creditworthiness and constant access to the international capital market are essential for implementing our ambitious investment programme. In these times, none of this can be taken for granted,” says Peter Rüth, CFO of Amprion. At the same time, a high degree of financial flexibility is important. Amprion's financing strategy is based on a variety of financing instruments. “The success of these two transactions confirms the confidence of banks and investors in our strategy and our sustainable business model," adds Peter Rüth.

The bond issuance and the increase of the syndicated loan agreement were carried out with the participation of the following banks: Bayerische Landesbank, Commerzbank AG, DZ BANK AG, ING, Landesbank Hessen-Thüringen, Landesbank Baden-Württemberg, SEB and UniCredit.
