What Are Biologicals & Why Use Them?

4

What are they? Biologicals are microorganisms, plant extracts, pheromones, soaps, fatty acids & other natural substances lumped into three categories:

Why use them? Biologicals offer key benefits to manufacturers, growers & consumers:

Natural & Safe

• Environmentally friendly production

• Safe for growers/workers to handle

• Healthier for consumers to eat

• No residues (especially important for export markets)

More Effective

• Improved yields & quality

• Minimized risk of pest resistance

• Can be used in both organic production, as well as conventional farming

• Flexible production schedules

Shorter Timeline & Cost

• Faster time to market • ~4 years for biologicals vs. 10+

years for chemicals• EPA allows an expedited

registration for biologicals

• Significantly lower development cost (<$10M for biologicals vs. $280M for chemicals)

Biological Category Biopesticides Biostimulants Biofertilizers

Use Crop Protection Crop Protection Crop Nutrition

Regulatory EPA-Registered State Registered State Registered

New Entrants Few Many Many

MBI Products Yes (6 products) Target Market No

NASDAQ: MBIISmart. Natural. Solutions.

Since MBI’s products are also used in conventional farming, the current market opportunity for our 6 products exceeds $30B

The global biopesticides market in 2016 was $3.4B in 2016 & is projected to reach $8.8B by 20221

Biopesticides today hold only 5% of the total crop protection market, representing significant room for growth2

In a study conducted by UC Davis, the market for biopesticides in the cannabis industry is estimated to grow from $91M in 2016 to $1.4B in 20213

The biopesticide market is growing at a CAGR of 17.4% vs. ~2.0% in the chemical pesticide market4

GAAP Revenue Product Shipments

Operating Expenses Gross Margins

Our GAAP revenue recognition policy requires us to defer some revenues to certain customers on the sell-through recognition method. We do not grant any return rights to these customers & deferred revenues are recognized over time. Cash is collected on normal terms, exactly the same as with our sell-in customers, & is not affected by this recognition method.
