The principal place of business
address of each of the Reporting Persons is 410 Park Avenue, 17^th Floor, New York, New York, 10022.

Item 4. Purpose of Transaction.

This Amendment No. 6 reports (i) the disposition by the Reporting Persons of shares of the Common Stock of the Issuer pursuant to the
Issuers tender offer which closed on October 3, 2018, with shares purchased and consideration paid on October 9, 2018, and (ii) increases in Messrs. Trafelet and Brokaws respective beneficial ownership of the Issuer since
the filing of Amendment No. 5.

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

The Issuer filed Amendment No. 3 to its Tender Offer Statement on Schedule TO with the SEC on October 9, 2018 announcing the final
results of the Issuers tender offer (the Tender Offer). On October 9, 2018, the Issuer accepted for purchase, at a price of $34.00 per share, an aggregate of 752,234 shares of the Common Stock of the Issuer that were
validly tendered and not withdrawn in the Tender Offer. Because the Tender Offer was oversubscribed, the number of shares of Common Stock of the Issuer accepted for purchase by the Issuer from each tendering stockholder was prorated, at a proration
factor of approximately 14.17%. The shares of Common Stock of the Issuer accepted for purchase by the Issuer included 525,052 shares of Common Stock tendered by 734 Investors.

As disclosed in the Issuers Offer to Purchase attached to the Issuers Schedule TO filed with the SEC on September 5, 2018, as
amended, 734 Investors and 734 Agriculture, in addition to having sold shares of Common Stock to the Issuer in the Tender Offer, reserves the right to privately negotiate the repurchase by the Issuer of an additional portion of their Common Stock
after the date of this filing to help fund a one-time debt obligation of 734 Investors and 734

Agriculture. Any such privately-negotiated repurchase of any Common Stock held by 734 Investors and 734 Agriculture after the date of this filing may occur on terms more or less favorable than
the terms of purchase in the Tender Offer, or at a per share price greater or less than the purchase price in the Tender Offer. However, there is currently no agreement between 734 Investors and 734 Agriculture, on the one hand, and the Issuer, on
the other hand, related to such additional repurchase.

In addition, as previously disclosed on the applicable Reporting Persons
respective Form 4s, (i) on December 31, 2016, Mr. Brokaw was granted a stock option to purchase 225,000 shares of Common Stock of the Issuer at an exercise price of $27.15 per share, pursuant to a nonqualified option agreement (the
Brokaw December Option Agreement) issued under the Issuers Stock Incentive Plan of 2015, of which options to purchase 187,500 have been subsequently forfeited, leaving options to purchase 37,500 shares of Common Stock (the
Brokaw December Options), (ii) on December 31, 2016, Mr. Trafelet was granted a stock option to purchase 300,000 shares of Common Stock of the Issuer at an exercise price of $27.15 per share, pursuant to nonqualified
option agreement (the Trafelet December Option Agreement) issued under the Issuers Stock Incentive Plan of 2015 (the Trafelet December Options, and together with the Brokaw December Options, the
December Options), and (iii) on September 4, 2018, Mr. Trafelet was granted a stock option to purchase 210,000 shares of Common Stock of the Issuer at an exercise price of $33.60 per share, pursuant to a
nonqualified option agreement (the Trafelet September Option Agreement, and collectively with the Brokaw December Option Agreement and Trafelet December Option Agreement, the Stock Option Agreements) issued
under the Issuers Stock Incentive Plan of 2015 (the September Options).

The December Options and the September
Options vest (subject to terms in the applicable Stock Option Agreements as to the respective term of the option, continued employment and accelerated vesting) only if certain respective specified trading price thresholds for the Issuers
Common Stock are achieved over a consecutive 20-day trading period within the respective term of the option. The specific trading price thresholds, vesting schedules and other terms of the December Options and
September Options are set forth in the full Stock Option Agreements, which are incorporated hereto by reference to the Stock Option Agreements attached as Exhibits 2, 3, and 4 to this Amendment No. 6.

Item 5. Interest in Securities of the Issuer.

Item
5 of the Schedule 13D is hereby amended and restated as follows:

(a), (b) Items 7 through 11 and 13 of each of the cover pages of
this Amendment No. 6 are incorporated herein by reference. None of the December Options or September Options are currently exercisable within 60 days of the date of this Amendment No. 6 and therefore the underlying shares of Common Stock
are not deemed to be beneficially owned by the Reporting Persons under Rule 13d-3 of the Act as of the date of this Amendment No. 6.

(c)

Disposition pursuant
to the Issuer Tender Offer. As described in Item 4 above, on October 9, 2018, 734 Investors sold 525,052 shares of Common Stock of the Issuer to the Issuer in accordance with the Tender Offer, and 734 Investors received $17,851,768.00 in the
aggregate for such shares.

Except as described in this Schedule 13D, as amended, to the knowledge of any of the Reporting Persons, no
other transactions in the Common Stock were effected by any of the Reporting Persons or any of the entities or persons named in Item 2 hereto during the 60 days prior to the date of this Amendment No. 6.

(d) Except as set forth in this Schedule 13D, as amended, to the knowledge of the Reporting Person, no person had the right to receive
or the power to direct the receipt of dividends from, or the proceeds from the sale of, securities covered by this Schedule 13D, as amended.

(e) Not applicable.

Item 6.
Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

the interest rate to the one-month LIBOR rate plus 2.5%, and extend the maturity date to November 1, 2019, among other amendments. Any description of the Credit Agreement and the margin loan obtained
pursuant to the Credit Agreement is qualified in its entirety by reference to the full Credit Agreement, as amended, which is incorporated hereto by reference to such Credit Agreement as previously filed with the Schedule 13D, and the amendments
thereto as attached as Exhibits 5, 6, 7, and 8 to this Amendment No. 6.
