In accordance with General Instruction B, item (iii), attached herewith as
Exhibit 99.1 is a press release, dated April 25, 2007, announcing Stolt-Nielsen
S.A.'s ("SNSA") fourth quarter and 2006 year-end results.

The attached press release shall be deemed to be incorporated by reference into
the prospectuses forming a part of SNSA's Registration Statements on Form S-8
(No. 033-28473, No. 333-06958, No. 333-11178 and No. 333-121315) and to be a
part of such prospectuses from the date of the filing thereof.

The attached  press release  contains  "forward-looking  statements"  within the
meaning of Section  27A of the  Securities  Act of 1933 and  Section  21E of the
Securities  Exchange Act of 1934.  These statements may be identified by the use
of words like "anticipate,"  "believe,"  "estimate,"  "expect," "intend," "may,"
"plan,"  "project,"  "will,"  "should,"  "seek,"  and similar  expressions.  The
forward-looking  statements reflect SNSA's current views and assumptions and are
subject to risks and uncertainties.  The following factors, and others which are
discussed in SNSA's public filings and submissions with the U.S.  Securities and
Exchange  Commission,  are among those that may cause actual and future  results
and trends to differ  materially  from SNSA's  forward-looking  statements:  the
general  economic  conditions  and  competition in the markets and businesses in
which SNSA operates; changes in the supply of and demand for parcel tanker, tank
container and terminal  capacity in the markets in which SNSA operates;  changes
in the supply of and demand for the products SNSA  transport,  particularly  the
bulk liquids,  chemicals and other  specialty  liquids that form the majority of
the   products   that  SNSA   transports;   prevailing   market  rates  for  the
transportation  services that SNSA offers and the fish products that SNSA sells;
changes in bunker fuel  prices;  the cost and  feasibility  of  maintaining  and
replacing  the  Company's  older  ships and  building or  purchasing  new ships;
uncertainties  inherent  in  operating  internationally;  the  outcome  of legal
proceedings;  SNSA's  relationship  with significant  customers;  the outcome of
discussions with customers  concerning potential antitrust claims; the impact of
negative  publicity;  environmental  challenges  and natural  conditions  facing
SNSA's  aquaculture  business;  the  impact of laws and  regulations;  operating
hazards,  including  marine  disasters,  spills  or  environmental  damage;  the
conditions  and  factors  that  may  influence  the  decision  to  issue  future
dividends;  and the market for long-term  debt. Many of these factors are beyond
SNSA's ability to control or predict.  Given these factors, you should not place
undue reliance on the  forward-looking  statements.  Should one or more of these
risks or uncertainties  occur, or should  management's  assumptions or estimates
prove  incorrect,  actual  results  and  events may vary  materially  from those
discussed in the forward-looking statements.
