PENFORD REPORTS THIRD QUARTER FISCAL YEAR 2014 FINANCIAL RESULTS

CENTENNIAL, CO, July 7, 2014 – Penford Corporation (Nasdaq: PENX), a leader in ingredient systems for food and industrial markets, today reported third quarter and year-to-date fiscal year 2014 results.

The Company reported net income of $3.1 million, or $0.24 per diluted share, for the third quarter ended May 31, 2014. Consolidated sales for the quarter were $119.4 million compared with $121.7 million last year, primarily because lower corn prices that were passed through to paper industry customers reduced industrial starch and by-products revenue. The Company’s gross margin improved, benefiting from higher Industrial Ingredients profitability. Consolidated operating income increased 15% to $4.9 million.

Third quarter results included a one-time $1.0 million non-operating gain in the Industrial Ingredients division. The Company satisfied conditions of a forgivable government loan and had the remaining repayment obligations waived. The loan was extended following the 2008 flood event that impacted the Company’s operations in Cedar Rapids. Results in the division were also slightly improved by a change in the estimated service lives used to calculate depreciation expense, as explained below. In addition, the Company incurred one-time costs associated with the acquisition of Gum Technology, which are included in the quarterly results of the Food Ingredients division.

Reconciliation of Non-GAAP Measure

To supplement the segment and consolidated financial results prepared in accordance with generally accepted accounting principles (“GAAP”), the Company utilizes a non-GAAP financial measure, net income (loss), before interest, taxes, depreciation and amortization expense (“EBITDA”). The Company uses EBITDA to evaluate performance and establish goals. The Company believes that this measure is valuable to investors in assessing the Company’s operating results when viewed in conjunction with GAAP results. This non-GAAP measure is not a substitute for, or an alternative to, the corresponding measure calculated in accordance with GAAP.
