Covestro stock market listing: price range and gross proceeds adjusted

Leverkusen, October 1, 2015 -

- Current deterioration and high volatility in capital markets

- Targeted gross proceeds reduced from EUR 2.5 billion to EUR 1.5 billion

- Bookbuilding range reduced to between EUR 21.50 and EUR 24.50

- Net indebtedness unchanged at EUR 4 billion

- Initial listing now planned for October 6, 2015

In light of the current deterioration and volatility in the capital market
environment, Bayer and Covestro have adjusted the targeted gross proceeds and
price range for the issuance of Covestro shares ahead of the planned stock
market listing of the polymer company. The proceeds from the capital increase
are now expected to be EUR 1.5 billion instead of EUR 2.5 billion originally.
The issue price is now in the range of EUR 21.50 to EUR 24.50 per share. It was
previously intended to offer the shares at between EUR 26.50 and EUR 35.50. The
reduced proceeds will be mitigated by increasing the capital contribution by
EUR 1 billion. Thus Covestro's net debt together with pension liabilities will
be unchanged at EUR 4 billion.

The addendum to the stock market prospectus indicating the amended terms of
issue still requires approval from the German Financial Supervisory Authority
(BaFin), which is expected during the course of today. The offer period for the
new shares is being extended until 12:00 midday on Friday, October 2, 2015 for
retail investors interested in subscribing for the shares being offered
publicly in Germany and Luxembourg. An extension until 1:00 p.m. on the same
day applies for institutional investors.

Since the start of the bookbuilding phase on September 21, 2015, the capital
market situation has deteriorated significantly. External factors such as
uncertainty surrounding future economic growth in China or the Federal
Reserve's interest rate policy have contributed to increased market volatility.
In addition, the stock market has been impacted by the negative headlines from
the automotive sector.

Covestro, one of the world's leading polymer manufacturers, intends to issue
between 61.2 million and 69.8 million new shares by way of a capital increase.
The number of shares issued will be aligned with the issue price. On account of
the changed parameters, the free float will be between around 30.4 and 33.3
percent. The remaining shares will be held by Bayer AG. Stabilization measures
equivalent to as much as 10 percent of the emission volume are possible within
30 days of the initial listing in the regulated market segment (Prime Standard)
of the Frankfurt Stock Exchange, now planned for October 6, 2015.

The new bearer shares (ISIN DE0006062144, ticker symbol 1 COV) are being
offered publicly in Germany and Luxembourg to private and institutional
investors. In other countries, only institutional investors are being contacted
in the course of private placements.
