Exhibit 99.4

Dear Valued Supplier,

The Span-America board of directors has approved the acquisition of Span-America by Savaria Corporation, a dynamic, industry-leader in the manufacture and sale of accessibility lifts, wheelchair-accessible vans and elevators. Span-America’s news release announcing the transaction is attached.

We expect the transaction to close by the end of June 2017. Until that time, Span-America and Savaria will remain separate companies and it is business as usual. We will continue to honor our contracts and agreements under existing terms, and your contacts at Span-America will remain the same.

We deeply value your service and support, and thank you for your partnership during this transition. If you have questions beyond the attached FAQ, please feel free to reach out to your normal Span-America contact.

Sincerely,

James D. Ferguson
