The Woodlands, TX – Huntsman Corporation (NYSE: HUN) today reported fourth quarter 2015 results with
revenues of $2,332 million and adjusted EBITDA of $240 million.

Peter R. Huntsman, our President and CEO, commented:

“During the fourth quarter this year, EBITDA from our cyclical businesses – which include our MTBE, ethylene
and TiO2 products – decreased approximately $78 million compared to the prior year. This overshadowed the
real strength of our portfolio which is in our downstream differentiated businesses. Excluding approximately
$24 million of foreign currency headwind, the EBITDA from our differentiated businesses improved
approximately $50 million compared to the prior year or 27%.

“In 2016, primarily as a result of lower priced oil and a lower global economic growth environment, we expect
continued EBITDA pressure on our cyclical businesses. Growth from our differentiated businesses will offset
cyclical pressure and inflationary costs such that we expect our 2016 EBITDA to be a similar amount to 2015.
Importantly however, we expect our free cash flow generation to improve by $350 million in 2016 through lower
capital expenditures, restructuring and maintenance. In 2016 we will continue to pursue

Segment Analysis for 4Q15 Compared to 4Q14

Polyurethanes

The decrease in revenues in our Polyurethanes division for the three months ended December 31, 2015
compared to the same period in 2014 was due to lower average selling prices and lower MTBE sales volumes.
MDI average selling prices decreased in response to lower raw material costs and the currency exchange
impact of a stronger U.S. dollar primarily against the Euro. PO/MTBE average selling prices decreased in-line
with lower pricing for high octane gasoline. MDI sales volumes increased due to higher demand as well as
competitor outages in the Asian region. The decrease in adjusted EBITDA was primarily due to lower MTBE
contribution margins and the foreign currency exchange impact of a stronger U.S. dollar primarily against the
Euro partially offset by higher MDI contribution margins.
