Please read the Company’s Annual Report on Form 10-K, filed today with the U.S. Securities and Exchange Commission (the “SEC”), which can be retrieved from the SEC’s website at www.sec.gov or from the Company’s website at www.arganinc.com.

Summary Annual Information: (dollars in thousands, except per share data):

Highlights for the Year:

·                  Revenues increased 8% to $413 million for the year ended January 31, 2016 (“Fiscal 2016”) as compared to $383 million for the prior year.

·                  Our gross profit percentage increased to 24.1% for Fiscal 2016 as compared to 21.8% for the prior year.

·                  EBITDA attributable to the stockholders of Argan increased 20% to $62.9 million for Fiscal 2016 as compared to $52.2 million for the prior year.

·                  Net income attributable to the stockholders of Argan increased 19% to $36.3 million for Fiscal 2016 as compared to $30.4 million for the prior year.

·                  The contract backlog of GPS increased 171% to $1.1 billion at the end of Fiscal 2016 as compared to $423 million at the end of the prior year.  Subsequent to Fiscal 2016, an additional $400 million was added to the contract backlog.

·                  GPS started five new power plant projects during Fiscal 2016.

·                  In December, we acquired The Roberts Company (“Roberts”), a fully integrated fabrication, construction and plant services company, for $0.5 million and we paid off $16 million in Roberts debt obligations.

·                  In May, we acquired Atlantic Projects Company (“APC”), a leading provider of construction and technical services for power generation, oil and gas, industrial and process industry customers worldwide, for $11.1 million.

Fiscal Year Results:

Revenue increased 8% to $413 million over last year primarily due to consistent year over year revenue from GPS and the addition of revenues from the two acquisitions, APC and Roberts, in Fiscal 2016.   Our gross profit margins increased to 24.1% during Fiscal 2016 reflecting the effective performance of the construction teams during the year, though new work in the latter part of the year had lower gross margins. Selling, general and administrative expenses increased primarily due to the additions of APC and Roberts and related acquisition costs.  Net income attributable to our stockholders for Fiscal 2016 increased 19% to $36.3 million, or $2.42 per diluted share, from $30.4 million, or $2.05 per diluted share, for the prior year due primarily to the aforementioned revenues and gross profit increases. Likewise, EBITDA attributable to our stockholders for Fiscal 2016 increased 20% to $62.9 million, or $4.19 per diluted share, from $52.2 million, or $3.52 per diluted share, for the prior year.

Commenting on Argan’s results, Rainer Bosselmann, Chairman and Chief Executive Officer, stated, “This has been a significant year of growth for us.  Revenues and gross profit are at record levels and we expect that growth to continue into next year.  We started five new power plant projects at Gemma this year and our total backlog has increased to over $1.5 billion with the addition of the CPV Towantic project. Our two new acquisitions will increase our geographical reach to international power markets, enhance vertical synergies with certain supply services and help diversify our revenue streams for our stockholders. We believe we are well positioned for the coming years.”

Fourth Quarter Results:

Revenues increased 2% to $116 million over last quarter primarily due to $15.3 million in revenues from Roberts which we acquired in December, partially offset by a decrease in revenue at GPS during the fourth quarter reflecting a transitional period from older projects to new projects.  Gross margins decreased 2.8% reflecting lower margins on the new GPS projects and a loss at Roberts, but remain robust overall at 20.2%.  Selling, general and administrative expenses increased $3.5 million primarily due to the addition of Roberts and related acquisition costs as well as year-end incentive compensation costs.  Net income attributable to our stockholders for the fourth quarter decreased 38% to $6.7 million, or $0.45 per diluted share, from $10.8 million, or $0.72 per diluted share, for the third quarter.  Likewise, EBITDA attributable to our stockholders for the fourth quarter decreased 30% to $12.8 million, or $0.85 per diluted share, from $18.2 million, or $1.21 per diluted share, for the third quarter.

Subsequent Events:

·                  In March, GPS received from Competitive Power Venture’s Towantic Energy Center project (“CPV Towantic”) the full notice-to-proceed with EPC activities for a 785 MW combined cycle power plant to be located in Oxford, Connecticut.  GPS total backlog increased to over $1.5 billion with the addition of CPV Towantic, when added to the GPS backlog balance at January 31, 2016.

·                  In March, GPS received from NTE Energy the full notice-to-proceed with EPC activities for a 475 MW combined cycle power plant to be located in Kings Mountain, North Carolina.
