Forward-Looking Statements
This communication contains “forward-looking statements”, including as defined
under applicable laws, such as the US Private Securities Litigation Reform Act
of 1995. Forward-looking statements provide the Company’s current expectations
or forecasts of future events. Forward-looking statements include statements
about the Company’s expectations, beliefs, plans, objectives, intentions,
assumptions and other statements that are not historical facts or that are not
present facts or conditions. Words or phrases such as “anticipate,” “believe,”
“continue,” “estimate,” “expect,” “hope,” “intend,” “may,” “ongoing,” “plan,”
“potential,” “predict,” “project,” “should,” “will” or similar words or phrases,
or the negatives of those words or phrases, may identify forward-looking
statements, but the absence of these words does not necessarily mean that a
statement is not forward-looking. Forward-looking statements are subject to
known and unknown risks and uncertainties and are based on potentially
inaccurate assumptions that could cause actual results to differ materially from
those expected or implied by the forward-looking statements. The Company’s
actual results could differ materially from those anticipated in forward-looking
statements for many reasons, including as described in the Company’s filings
with the SEC. Accordingly, you should not unduly rely on these forward-looking
statements, which speak only as of the date of this communication. Factors that
could cause actual results to differ materially include, but are not limited to,
the Company’s operating or financial results; the Company’s liquidity, including
its ability to service its indebtedness; competitive factors in the market in
which the Company operates; shipping industry trends, including charter rates,
vessel values and factors affecting vessel supply and demand; future, pending or
recent acquisitions and dispositions, business strategy, areas of possible
expansion or contraction, and expected capital spending or operating expenses;
risks associated with operations; broader market impacts arising from war (or
threatened war) or international hostilities; risks associated with pandemics,
including effects on demand for oil and other products transported by tankers
and the transportation thereof; and other factors listed from time to time in
the Company’s filings with the SEC. Except to the extent required by law, the
Company expressly disclaims any obligations or undertaking to release publicly
any updates or revisions to any forward-looking statements contained herein to
reflect any change in the Company’s expectations with respect thereto or any
change in events, conditions, or circumstances on which any statement is based.
You should, however, review the factors and risks the Company describes in the
reports it files and furnishes from time to time with the SEC, which can be
obtained free of charge on the SEC’s website at www.sec.gov.
