	Penford Corporation Reports First Quarter Fiscal 2006 Results

CENTENNIAL, Co., December 20, 2005 — Penford Corporation (Nasdaq: PENX), a global leader in ingredient systems for food and industrial applications, today reported financial results for the first quarter of fiscal 2006.

Penford reported net income for the quarter ended November 30, 2005 of $0.2 million, or $0.02 per diluted share, compared to a net loss of $3.8 million, or $0.43 per diluted share, for the same quarter last year. First quarter fiscal 2006 results included $0.6 million of severance expenses in the Australian and Industrial operations as well as $0.3 million of pre-tax stock-based compensation expense. The net loss in the first quarter of fiscal 2005 included $4.1 million in strike-related operating costs in the industrial ingredients business.

The Company has adopted the accounting requirements of Financial Accounting Standards Board Statement No. 123R, “Share-Based Payment.” This statement requires recognition of the cost of share-based compensation in the financial statements beginning with the first quarter of fiscal 2006. Approximately $0.1 million of compensation expense has been recognized by the Company’s operating units, with $0.2 million recorded as corporate operating expenses.

Consolidated sales for the first quarter of fiscal 2006 rose 8% to $77.9 million from $72.1 million last year. Volume increases contributed 6% to the total sales gain with an additional 2% attributable to higher unit selling prices and stronger currency exchange rates. Consolidated gross margin as a percent of sales expanded to 13.3% from 4.5% last year. The return to pre-strike operating rates in the North American Industrial Ingredients business contributed 5.3% to the margin increase. Improvements in volumes, unit prices, product mix and manufacturing efficiencies added 3.5% to the ratio despite rising natural gas and chemical costs worldwide. Consolidated operating expenses increased to $7.7 million from $5.8 million last year on increased professional fees and employee costs, including severance and stock-based compensation costs. Interest expense of $1.3 million was comparable to last year.

Segment Results

First quarter fiscal 2006 sales at the Industrial Ingredients business rose 10% to $38.5 million, due to a 6% increase in volumes as well as higher average selling prices and favorable product mix changes. Quarterly gross margin as a percent of sales improved to 9.3% from last year’s negative margin of 5.1%. Achieving pre-strike operating utilization rates and manufacturing metrics changed the margin by 10.7%. Revenue gains and improved grain procurement costs were partially offset by $3.0 million in additional natural gas and chemical costs. Operating income improved from the same period last year by $5.0 million to $0.6 million.

First quarter sales at the Australia/New Zealand business declined 2% to $24.6 million from $25.2 million last year. The impact of stronger foreign currency exchange rates partially offset decreased volumes of lower margin starches. Gross margin as a percent of sales expanded to 10.5% from 8.0% a year ago on improved production yields and throughput at every manufacturing site. The business was repositioned during the first quarter to accelerate new customer focused initiatives. Employee severance costs related to this program increased operating expense by $0.4 million. Operating income for the first quarter of fiscal 2006 was $0.7 million compared with $0.6 million last year.

First quarter Food Ingredients—North America revenues grew 23% to $15.1 million from $12.3 million a year ago. Sales of potato coating formulations grew by 10% with all other applications expanding by more than 50%. Gross margin as a percent of sales increased to 28.1% from 24.4% a year ago as higher revenue and improved plant utilization more than offset higher energy and chemical costs. Operating income for the first quarter of fiscal 2006 rose to $2.4 million from $1.4 million in the prior year.

“We reported improved operating income in every business segment during the first quarter despite the challenge of rapidly escalating energy and chemical costs,” said Tom Malkoski, Penford’s chief executive officer. “Sales of value-added food and industrial applications are accelerating. Our plants are producing more efficiently. The strategy for success is showing results.”
