Agrium Comments on ISS Report

CALGARY, ALBERTA -- (Marketwire) -- 03/27/13 -- ALL AMOUNTS ARE STATED IN U.S.$

Agrium Inc. (TSX: AGU) (NYSE: AGU) today commented on the report issued today by Institutional Shareholder Services Inc. ("ISS"). The report's recommendation puts ISS at odds with the unequivocal statements of support for Agrium's Board nominees issued over the past week by three of Agrium's largest institutional shareholders: Letko Brosseau & Associates, Aimco and bcIMC.

The report's recommendation also puts ISS at odds with three other proxy advisory firms, including Glass, Lewis, a leading international proxy advisory firm, Pensions Investment Research Consultants (PIRC), a UK-based proxy advisory firm, and Egan-Jones. It also puts ISS at odds with the views of the equity research community, which has strongly endorsed Agrium's integrated strategy, as well as the company's analysis of JANA's flawed ideas, and at odds with independent corporate governance experts, who have severely criticized JANA's 'golden leash' pay arrangements for their short-term orientation and for undermining notions of director independence.

As an equity research analyst from CIBC wrote this morning, "ISS' reasoning includes that JANA's goal is NOT to break up (Agrium) (clearly ISS drinking a bit of JANA's "Koolaid" as JANA has been very clear with myself and others from day 1 that AGU's break-up was JANA's exit strategy)."

Likewise, ISS has accepted JANA's portfolio weighted methodology, which has been rejected by all 29 equity research analysts covering Agrium. Glass, Lewis has said "JANA relies upon a poorly justified weighting methodology in order to arrive at figures sufficient to support the remainder of its arguments. We regard this analysis as misleading at best, and believe shareholders should refrain from relying on any conclusions derived therefrom."

"In addition to being offside with the equity research community, leading independent governance experts, three other proxy advisory firms and many of Agrium's largest institutional shareholders, ISS' decision runs counter to its own published criteria for evaluating short-slate dissident campaigns in Canada," said Agrium Board Chair Victor J. Zaleschuk. "Those criteria require a dissident to demonstrate that Board change is warranted. Having completely failed this test, there is no basis for JANA to receive even a single board seat. It is also shocking that ISS - as a self-proclaimed arbiter of good governance - would effectively endorse JANA's 'golden leash' payment scheme. This decision puts ISS way outside the mainstream of the corporate governance community. ISS simply got this one wrong."

"A significant number of large institutional funds have told us they will override any ISS recommendation in favor of JANA and vote instead for Agrium's Board nominees on the white proxy. As with several other situations where ISS has supported dissident slates only to later see those dissident slates defeated by shareholders, we are confident that our shareholders will rightly and roundly defeat JANA's nominees," said Mr. Zaleschuk.

JANA is seeking to break up Agrium and implement other ideas that Agrium has demonstrated would destroy shareholder value. JANA has provided no credible evidence to the contrary and has little support from other Agrium shareholders or the equity research community. JANA has also failed to demonstrate that its dissident nominees can be trusted to act in the best interests of the corporation given their explicit and short-term oriented financial ties to JANA.

On this point, Aimco, which is one of Agrium's largest shareholders and one of the largest investment funds in Canada, wrote: "We struggle with a governance model where JANA Partner's dissident nominees are compensated in a different manner than other directors. This has negative effects on the board: lack of independence, fragmentation, and reduced efficacy. JANA's plan is misaligned with the interests of long-term shareholders."

ISS' decision fails to properly consider the following facts:

--  Agrium's integrated strategy has delivered a 467% shareholder return
    since it was initiated in late 2005

--  Agrium is one of the best performing stocks in North America over the
    past eight years, and on any accepted basis its 1-, 3-, and 5-year share
    price performance is very strong

--  Agrium's Board has an excellent governance track record, including a
    robust and ongoing board renewal program that since 2005 has added the
    fresh perspectives of seven of the current 13 highly-qualified Board
    members

--  Agrium delivered record earnings and strong cash flow in 2011

--  Agrium delivered record earnings and cash flow in 2012

--  Agrium has increased its dividend 18-fold since 2010, in line with
    increased earnings and cash flow and consistent with the actions of
    Agrium's competitors

--  Agrium, not JANA, structured its pending acquisition of the Agri
    Products business from Glencore, allowing Agrium to return C$900 million
    of excess proceeds directly to shareholders through a share repurchase
    in October 2012

--  By endorsing JANA's analysis and helping to promote its break-up plan,
    JANA's dissident nominees have jeopardized their credibility,
    objectivity and independence

--  As Agrium stated in a March 22, 2013 press release: "Agrium has
    maintained from the very beginning that JANA's "portfolio-weighted
    composite" is not a measure of performance that Agrium uses or accepts.
    Presentation of this concept by Agrium was simply to illustrate the
    misinformation in what JANA was advocating."

--  ISS wrongly attributes the use of EBIT/GP as "an appropriate measure for
    distribution companies" to Agrium. This too is plainly wrong. In a March
    19, 2013 letter to ISS, Agrium Executive Vice President and Chief
    Financial Officer Stephen Dyer, wrote:

    --  JANA Partners introduced this measure in their January 23, 2013
        presentation and continued to use it in their Proxy Circular even
        after Agrium's January 28, 2013 Analyst Day where we illustrated
        that Agrium retail's EBITDA margins were highly superior to those of
        our competitors.

    --  EBIT to Gross Profit is not a metric that either Agrium or its
        competitors use. We do not see value in this measure as it is not a
        margin calculation but a ratio mixing cash and non-cash accounting
        numbers. Agrium retail has very strong margins as evidenced by our
        high EBITDA margins which you have reviewed. Agrium retail margins
        have always significantly exceeded margins of our closest direct
        agricultural retail peers (Royster-Clark and UAP). Agrium has
        consolidated Royster-Clark, UAP and many tuck-in acquisitions (all
        with EBITDA margins averaging well below 6%) since 2006 and has
        successfully increased its total North American EBITDA margins to
        over 9%.

--  JANA remains committed to the "golden leash" payment scheme despite
    strong negative reactions by shareholders, governance experts and others

--  JANA's dissident director pay scheme demonstrates that JANA's nominees
    are not aligned with other shareholders and that JANA has a short-term
    vision for Agrium of less than 30 months
