On Tuesday, lighting equipment maker Acuity Brands Inc. (NYSE: AYI) reported that its fiscal first-quarter profit dropped 38% due to lower demand for its products. On the other hand, food and animal safety company Neogen Corp. (NASDAQ: NEOG) said that its second-quarter profit rose 20%, boosted by acquisitions.

For the quarter that ended Nov. 30, Acuity Brands earned $19.4 million, or 48 cents per share, which was 33.3% lower than in the same quarter of the previous year. Excluding a pretax charge related to the consolidation of facilities, the company posted an adjusted operating profit of $55.8 million, or 82 cents per share. Sales fell 11% to $452.0 million. Analysts polled by Thomson Reuters had expected a profit of 76 cents per share on $461.3 million in revenue.

Acuity said the rapid decline in demand for lighting products and a dramatic jump in material and component costs during the quarter were unprecedented. The Atlanta-based company said it expects the second quarter to be challenging due to the turbulent economic environment, and for demand from its core markets to be lower for fiscal 2009.

Acuity's share price fell 26 cents, or 0.7% Tuesday, and are 16.5% lower than a year ago.

After the turn of the calendar page, quarterly reporting resumes this week. Analysts surveyed by Thomson Reuters are expecting to see strong earnings growth from fertilizer producer Mosaic Co. (NYSE: MOS), biotech giant Monsanto Co. (NYSE: MON), and Neogen Corp. (NASDAQ: NEOG), which produces food safety and animal health products. Mosaic's estimated earnings per share of $1.43 for the fiscal second quarter would be 41.9% higher than a year ago, and its revenue estimate of $3.0 billion is 36.7% higher. Monsanto's $0.59 per share projection for the fiscal first quarter is 22.0% higher and sales of $2.4 billion are up 14.9%. And Neogen's second-quarter $0.25 per share would be 12.0% higher, while its sales of $32.3 million are up 18.6%. All three have tended to beat expectations in recent quarters, and all three have buy recommendations from a consensus of analysts. Mosaic and Monsanto have recently announced dividends, and their share prices have fallen 62.3% and 39.0%, respectively, from a year ago. The share price of Neogen, which recently announced share buybacks, is only 0.8% lower.

Other companies expected to post modest earnings gains when they report this week include education company Apollo Group Inc. (NASDAQ: APOL), WD-40 Co. (NASDAQ: WDFC), and wine and spirits maker Constellation Brands Inc. (NYSE: STZ).

However, Constellation lowered its full-year profit outlook, in part due to costs from its recent acquisition of Fortune Brands Inc.

Acuity Brands Inc. (NYSE: AYI): Fiscal 2008 first-quarter earnings fell 7 percent, as a restructuring charge offset higher pricing and increased sales. The company earned $31.1 million, or 72 cents per share, compared with $33.6 million, or 77 cents per share, in the same quarter a year ago. Analysts had expected profit of 82 cents per share on revenue of $500.6 million, according to analysts polled by Thomson Financial.

It's been said that if the U.S. state of Georgia were an independent nation, it would have the 18th largest economy in world. The "Empire State of the South" ranked tenth in U.S. in per capita personal income in 2005, and has one of the fastest growing populations in the U.S. -- about a million additional people between 2000 and 2005. Its diverse industrial output ranges from peaches and peanuts, to textiles, food processing, and aircraft manufacturing, to publishing and tourism. Georgia is home to such corporate giants as Coca-Cola Co. (NYSE: KO); Delta Air Lines Inc. (NYSE: DAL); Home Depot Inc. (NYSE: HD); UPS (NYSE: UPS); Newell Rubbermaid Inc. (NYSE: NWL), and Equifax Inc. (NYSE: EFX).

The lighting equipment company Acuity (NYSE: AYI) yesterday announced that it plans to spin-off its specialty products unit directly to shareholders later this year. According to the press report, Acuity is pursuing this spin-off to allow each company to operate separately, create company-specific compensation plans, and so on. The company stands to save $6 million just from a simpler corporate structure. I tend to believe that breaking up unrelated businesses makes sense because each business will be more efficiently valued if it stands as a separate entity.

If you haven't yet read my post about the opportunity in spin-off investments, check it out here. Spin-offs are undoubtedly one of the most interesting and lucrative investment fields in today's world due to "structural undervaluation." But the spin-off opportunity is becoming more and more obvious in recent times thanks to receiving front-page headlines in newspapers. All that being said, I think Acuity will probably trade up into the spin-off as investors try to position themselves to ride the spin-off trade.

On a slightly unrelated note, I saw You Can be a Stock Market Genius in the bargain books section of Border's today -- that was the best $4 value investment I've ever seen.
