DEVCON REPORTS A $19.3 MILLION INCREASE IN 2004 NET INCOME,

INCLUDING AN $11 MILLION DOLLAR SETTLEMENT;

NAMES STEPHEN J. RUZIKA AS CHIEF EXECUTIVE OFFICER

DEERFIELD BEACH, Fla., Apr. 18—Devcon International Corp. (NASDAQ: DEVC) today reported an increase of $19.3 million in net income to $10.6 million ($2.09 per fully diluted share) for the year ended December 31, 2004 when compared to a net loss of $ 8.6 million ($ 2.57 per fully diluted share) for the previous year.

In 2004, revenue increased $13.8 million to $69.2 million, a 25 % increase when compared to 2003 revenue of $55.3 million. The operating loss decreased $6.4 million to $2.7 million when compared to the 2003 operating loss of $9.1 million. This significant improvement was principally a result of the Construction and Materials Divisions achieving a combined increase in gross margin of $7.6 million. During the fourth quarter of 2004 we announced the settlement of outstanding note receivables and various pending claims with the Government of Antigua and Barbuda, which resulted in other income amounting to $11.0 million.

The Construction Division continued to improve during 2004. Revenues increased by $7.9 million to $25.1 million when compared to $17.1 million during 2003. This division continued to experience improved revenue and related gross margin dollars in most of its operating areas, particularly the Bahamas. Currently, this division is expected to experience continued revenue growth accompanied by corresponding increases in aggregate gross margin dollars. However, due to the mix of projects currently being worked, accompanied by pending bids outstanding, the company currently anticipates that gross margin as a percentage of revenue may experience a minor decline in 2005.

The Materials Division revenue increased by $4.8 million to $43.0 million in 2004 when compared to $38.2 million in 2003. Operating losses decreased during the year, from $5.9 million in 2003 to $2.7 million in 2004, however this division did record an operating loss of $2.6 million in the fourth quarter of 2004 compared to an operating loss of $0.9 million during the comparable quarter of 2003. Operating results during the fourth quarter of 2004 were significantly affected by negative inventory variations, an impairment of certain assets used in operations, and an increase in bad debt expense relating to certain trade and notes receivable. The increase in bad debt expense is principally attributable to the division’s Sint Maarten and Antigua operations. The implementation of additional review procedures and improved financial controls, which should reduce these write-downs in the future, is underway. In addition, the company is in the process of reviewing in detail this division’s operations and, based upon the findings, will implement the necessary changes to improve profitability, which the company anticipates will be achieved through price increases, where appropriate, and operating expense reductions. Based upon the outcome of this review the company may pursue an orderly divestment of all or certain of these operations.

During his tenure, he has directed the company’s growth from its beginnings as a small south Florida contractor to a major provider of construction materials and construction contracting services in the eastern Caribbean.

“During his long tenure Don has led the company to enjoy good success which has resulted in Devcon having a strong market share in the construction and materials business in the Caribbean. Don has laid a good foundation upon which we can build and I am excited about working closely with Dave Rulien, the president of the Construction and Materials and Utilities Divisions, as well as with all members of the Devcon team in the years ahead,” Mr. Ruzika said.

In addition, Devcon has also announced the following changes in senior management: Ron G. Lakey was named Vice President of Business Development, effective April 13, 2005, and Robert C. Farenhem has been appointed the company’s interim Chief Financial Officer.

“This is an exciting time for our company,” Mr. Smith said. “Steve’s continued leadership capabilities and broad experience should have an extraordinarily positive impact on our company’s growth. I am confident that his leadership as chief executive officer will position Devcon for its continued growth as a diversified services company.”
