Stellar Biotechnologies Reports Fiscal Year 2016 Financial Results

LOS ANGELES, Calif., December 14, 2016 – Stellar Biotechnologies, Inc. (Nasdaq: SBOT), a leading manufacturer of a key protein utilized in multiple immunotherapy development pipelines targeting cancers, Alzheimer's and lupus, among other diseases, today reported financial results for the fiscal year ended September 30, 2016 and provided an update on its business.

For fiscal year 2016, the company reported a 120% increase in product sales over the previous fiscal year as it expanded its customer base and increased shipments of its Stellar KLH protein. Through its collaboration and supply agreements, Stellar KLH is now a key ingredient in multiple clinical-stage immunotherapies. During the fiscal year, the company also completed a financing round with institutional investors and extended its market opportunities through a joint venture agreement to manufacture conjugated therapeutic vaccines.

“In fiscal year 2016 we met our strategic objectives, significantly strengthened our financial position and set the stage for Stellar to continue expanding our growth opportunities. We are closely monitoring our customers’ clinical trials and have a number of key objectives ahead to measure the company’s progress,” said Stellar President and CEO Frank Oakes. He noted that Stellar expects to move ahead with planned upgrades to its infrastructure. The company also plans to expand its commercial and clinical opportunities through new licensing, supply and research collaborations.

Stellar Chief Financial Officer Kathi Niffenegger indicated that the company would continue to prioritize the use of its working capital on manufacturing the company’s Stellar KLH™ protein and related processes. “With the $6.75 million equity financing in July, we are well capitalized to advance our future infrastructure and development projects, and we remain committed to maintaining a strong balance sheet,” she said.

Financial Results for the Fiscal Year Ended September 30, 2016

Total revenues increased by $0.51 million to $1.27 million for the fiscal year ended September 30, 2016 compared to $0.76 million for the fiscal year ended September 30, 2015. Product sales increased by $0.68 million to $1.24 million for fiscal year 2016 compared to $0.56 million for the prior year primarily due to an increase in product sales volume from an expanded customer base, including sales under supply agreements. The increase in product sales was partially offset by a $0.16 million reduction in contract services revenue due to the successful completion in December 2015 of services related to a two-year collaboration agreement.

Costs of sales and contract services increased by $0.24 million to $0.82 million for fiscal year 2016 compared to $0.58 million for the prior year primarily due to increased sales volumes.

Research and development expenses increased by $0.70 million to $1.73 million for fiscal year 2016 compared to $1.03 million for the prior year primarily due to increased research and development in aquaculture in the U.S. and Mexico, process development related to production and manufacturing, and product development.

General and administrative expenses increased by $0.10 million to $3.32 million for fiscal year 2016 compared to $3.23 million for the prior year primarily due to increased corporate and compensation expenses and expanded business development and investor relations activities.

Other income decreased by $1.64 million to an overall loss of $0.11 million for fiscal 2016 compared to an overall gain of $1.53 million for the prior year primarily due to a noncash change in fair value of warrant liability.

For fiscal year 2016, Stellar reported a net loss of $5.03 million, or $0.57 per basic share, compared to a net loss of $2.84 million, or $0.36 per basic share, for fiscal year 2015. The change was primarily due to significant fluctuations in non-cash gain/loss in fair value of warrant liability and non-cash foreign exchange gain/loss, as well as increased research and development expenses, which were partially offset by increased product sales.

At September 30, 2016, the company had working capital of $11.48 million. Cash, cash equivalents and short-term investments totaled $11.41 million. Stellar management estimates that expenditures for the fiscal year ending September 30, 2017 will be approximately $6.0 million.
