Frequently Asked Questions Q & A from interested parties

Frequently Asked Questions (1) What is the overall strategy at Chase? “Stay the course” of continued growth in markets we serve via internal and external means, staying close to our core financial principles M&A Consolidation Organic growth in selected areas Review your product mix now and how it has changed over time? Chase has grown from its wire and cable roots into a broad range of industrial and construction-related markets, specializing in protective materials for high-reliability applications with specialized properties and formulations. What end markets are your products sold into? Changes over time? Our primary markets span multiple industries (telecommunications, electronics, energy distribution, automotive, appliance, general industrial, infrastructure (water, oil, gas), bridge & highway, commercial building, housing, medical, mining/drilling, etc.). Our fiscal 2015 acquisition of our specialty chemical intermediates product line, our fiscal 2017 acquisition of Resin Designs and our fiscal 2018 acquisition of Stewart Superabsorbents/Zappa-Tec (“Zappa Stewart”) represent major immediate and long-term opportunities for growth by providing us entry into new markets and expansion in certain markets we already serve.

Frequently Asked Questions (2) Do you have any significant customer concentration? No. During fiscal 2017, 2016 and 2015, no one customer accounted for as much as 10% of sales. The acquisitions that we have made in recent years have expanded our customer roster and broadened our end-market reach, reducing our customer and industry concentration as a welcome side-benefit. Are your products a “consumable” or a one-time purchase? Industrial Materials segment includes specified products that are used in or integrated into another company’s product with demand typically dependent upon general economic conditions. These could be viewed as "consumable" in nature. Construction Materials segment comprises principally project-oriented product offerings that are primarily sold and used as “Chase”-branded products. Each project could be viewed as a one-time purchase, although some projects extend over multiple years and some give rise to follow-on projects (and purchases). What is the cost of your product as a % of the product it is being sold into? Varies by product line, but we believe it to generally be a small part of the cost of the end product or project. How critical are your products to the performance of the products that they are incorporated into? Our products are not typically the “active” part of an end product (e.g., they do not transmit a signal or energy), but rather allow the end product to perform more reliably over time, protect its warranty and increase its durability.

Frequently Asked Questions (3) What is the principal way that you compete in the marketplace (i.e., cost/price, technology/value add, brand/reputation, breadth of offering, service, etc.)? All of the above are important to different products we offer, with differing levels of importance based on the end-market. We compete principally on the basis of technical performance, service, reliability, quality and price. What do you see as your primary competitive advantages in the market? We are a reliable supplier with a long track record of producing and delivering high-quality value-added products. In certain markets, we are differentiated through our depth and breadth of proven product solutions to meet a specific need. What % of your revenue is tied to products that have patents or IP protecting them? Relatively low on legally-protected IP, but our trade secrets are important to our success. We hold various patents, but we believe that they are not material to the success of our business. Do your products have substitutes (i.e., a different material/chemical, not necessarily a competitor’s product)? Most of our products face pressure from some form of substitution, but we believe we offer both tangible and intangible value to our customers over these alternatives. Of course, there are other companies that manufacture or sell products and services similar to those made and sold by us.

Frequently Asked Questions (4) Are your products sold direct or via distributors? Both. We sell through multiple means, depending on market and location. Are any of your products sold on a contract basis? Yes, many products have contracts covering price, volume, etc., but our standard terms and conditions do not include minimum purchase quantities, “take or pay” or exclusivity provisions. Have there been any new entrants into the markets that you serve in the last 3-5 years? Yes, there are always new entrants, or ones that re-appear based upon exchange rates and other factors. What singular competitor do you most find yourselves competing against for sales? Would any market participant’s exit radically improve your ability to win business and improve your financial results? Given the diversified nature of Chase’s product offerings and markets served, the elimination of any one or even two competitors would not dramatically improve the results of the Company as a whole. We compete by reliably supplying our customers quality products. Can you walk through your manufacturing process? They are usually one to three steps, including coating, laminating, blending, polymerizing, mixing, weaving, printing, slitting and containerizing.

Frequently Asked Questions (5) It seems like there is very minimal CapEx in your business? Explicit CapEx is fairly low, since our major pieces of production equipment have long useful lives and the technology changes slowly. However, CapEx is often embedded in M&A activity. While our reported “Purchases of property, plant and equipment” totaled $3,199, $2,046 and $2,642 for fiscal 2017, 2016 and 2015, respectively, these do not include: Resin Designs acquisition (fiscal 2017) - $623 in PP&E obtained Spray Products (India) Private Limited acquisition (fiscal 2016) - $1,027 in PP&E obtained Henkel specialty chemicals intermediates acquisition (fiscal 2015) - $1,064 in PP&E obtained NEPTCO acquisition (fiscal 2012) - $18,657 in PP&E obtained. We currently have several on-going capital projects that are important to our long-term strategic goals. Machinery and equipment will be added as needed to increase capacity or enhance operating efficiencies in our manufacturing plants. Also, we can readily increase production in our facilities through adding shifts, without needing to acquire additional equipment.

How important are automotive-related sales to your current results and planned future growth? The automotive industry is important to us, as our products are used throughout current vehicles. For example, HumiSeal and Resin Designs products are utilized in engine and cabin control systems, in-dash circuitry and displays; our polyurethane dispersions are utilized in headliners, dashes and soft-touch vinyl interior components; our polymeric microspheres are utilized in adhesives and coatings for weight and density reduction, along with lining systems for sound dampening; and our cable shielding tapes, among our oldest products, have sales into automotive industry markets. For the burgeoning electric vehicle market our materials are utilized in power/energy management systems and charging stations. A substantial slowdown in the automotive industry would hurt our results, but no one industry is critical to our future plans. Has your historical revenue growth been driven by volume, price or a combination of the two? Primarily volume, with M&A expansion also significantly contributing to growth. What are the appropriate long-term revenue growth rates to think of for your segments/products? Are these rates being driven by volume, price, or both? We do not provide earnings guidance. We predict both volume and price will play a part in revenue growth, based upon underlying commodity pricing fluctuations. Your gross margins have expanded by over 500 bps in the last few years. What are the primary drivers of this increase? How sustainable is your current margin profile? We continue to focus on the specialty chemical aspects of our business, and have divested some lower-margin non-strategic businesses in recent periods. Frequently Asked Questions (6)

Frequently Asked Questions (7) Your margins are higher than your peer group. What is the reason, and are they sustainable? Our focus has been and will be to follow our strategy of using our base knowledge and core competency of chemical formulation to address customer demand by providing value added protective material solutions. We believe the value we provide to a customer with an engineered solution that meets their requirements, coupled with security of supply, deserves the margins we derive. Our intent is to continue to build out this specialty chemical platform with acquisitions and organic growth and desire to sustain our margin profile. We have also sold some product lines and assets that did not meet our profitability requirements and did not fit our strategy. The revenue losses have been offset by our acquisitions, as well as organic growth in certain strategic product lines. In effect, we have replaced some low-margin business with higher-margin business, resulting in better overall margins for the Company. What are the primary raw materials in your COGS? We purchase a wide variety of commodity items, including petroleum-based solvents, films, yarns, and nonwovens, aluminum and copper foils, specialty papers, and various resins, adhesives and inks. Are you able to pass through raw material cost increases to your customers either contractually or on a spot basis? When raw material costs decline, do you typically keep some of this margin or pass it along to your customers? Short-term, we usually are able to keep the benefit from cost declines but have difficulty passing on cost increases. Over the longer term, these ebbs and flows work themselves through the supply chain.

Frequently Asked Questions (8) What is the mix of fixed versus variable costs in your business? We do not disclose, but we are focused on leveraging and reducing fixed costs. How much room is left on the consolidation strategy and streamlining of operations (i.e., what inning are you in)? There is room for further consolidation, with multiple “games” being played and therefore different “innings” for each project. An active and opportunistic M&A program means that we are always thinking about how to best use our current set of facilities and equipment. Please discuss your capital allocation philosophy and priorities going forward We will continue to use free cash flow and leveraged debt as our two main sources of capital to fund strategic initiatives. How will the Tax Cuts and Jobs Act affect your tax rate? The passage of the Tax Cuts and Jobs Act of 2017 during our second fiscal quarter is expected to affect the Company’s future results and financial position in multiple ways. For the whole of fiscal 2018 (which ends in August), the Company anticipates its annual effective tax rate to be lower than the 34.0% recognized in the first quarter. The new corporate tax rate in the Internal Revenue Code (the “Code”) will also require us to revalue our U.S. net deferred tax asset positions at a lower rate, which will result in a charge taken to earnings in the period this remeasurement occurs. We continue to evaluate and quantify further what effects the new Code will have on our operations and liquidity, including the phasing out of the domestic production deduction (Section 199) and new rules and rates related to the repatriation of foreign cash.

Frequently Asked Questions (9) You refinanced your previously existing debt agreement. What was the purpose of the refinancing and what is Chase’s strategy for utilizing the revolving debt? In December 2016, we replaced our preexisting term loan with a more flexible and larger revolver facility. The base facility, all revolver debt, is structured at $150 million, with an accordion feature of an additional $50 million under the same terms and conditions. The credit agreement allows for greater flexibility in our M&A program, maintains favorable borrowing rates and allows us to convert any portion to term debt. The Company plans to utilize the new revolving debt agreement in line with its existing core strategies, including using it in part to finance the December 2017 acquisition of Zappa Stewart. What is the maximum level of leverage that you are comfortable having on your balance sheet? Our all revolver debt agreement with BoA, Citizens Bank and JPMorgan calls for no more than a 3.25x leverage on EBITDA (as defined in the credit agreement), and that is our high-end comfort level. What is Chase’s priority for use of excess cash? The main focus of Chase Corp is to increase shareholder value through growth initiatives where the return is greater than the cost of capital. We focus on our Mergers, Acquisitions and Divestitures program as the first priority for this “excess” capital, as well as strategic market and product development efforts. Our variable debt structure allows us to pay down debt (de-lever) in times when a project is not ready for investment, and then subsequently use the debt structure to make accretive acquisitions. Our secondary priority would be to pay out special dividends. In view of Chase’s already low float, buying back shares is not currently in our plans.

Frequently Asked Questions (10) Given the recent trading price of CCF stock, has the Company considered the possibility of a stock split? With an increased “float” there might be a corresponding increase in investor interest in the stock. The majority of our investor base (in terms of ownership) is focused on liquidity, measured as total dollars per day in trades. Higher liquidity allows them to move quickly into and out of a position without impacting the share price. For these investors, who often take large positions in Chase (3-5% of a fund), price per share is not part of their decision-making process. Over the last 3 years our liquidity, as measured by dollars per day in trades, has increased tenfold. In 2014, we were trading approximately 8,000 shares a day on average at a price of ~$30/share, or roughly $250k/day. More recently, we are trading approximately 25,000 shares a day at a price of $100+ or $2.5mm/day. Since there are both one-time and recurring costs to splitting the stock, the cost/benefit to Chase and its shareholders is not attractive at this time, as we do not believe that a stock split would change the total dollars traded per day. We will continue to focus on what drives shareholder value, and we believe liquidity measured in terms of dollars per day is the best way to ensure that outcome.

Frequently Asked Questions (11) With regards to mergers and acquisitions, please discuss: How you source deals (i.e., bankers, sellers come to you, you approach sellers, etc.)? Yes to all. What internal resources you have dedicated to M&A? We utilize a cross-functional team made up of senior management and outside consultants. The integration process? We expect to fully integrate all new acquisitions into our business model with centralized administrative services and inclusion in our centrally-managed ERP environment. Opportunities for cost and/or revenue synergies? Each opportunity is unique, but we always look to leverage our fixed costs. The financial hurdles or returns you seek when doing M&A? We look for any acquisition to be accretive to our overall metrics (GM %, ROI, ROE, etc.). The level of M&A to expect going forward? Mergers, acquisitions and divestitures will continue to be an important part of our strategy.

Frequently Asked Questions (12) Can you walk through the strategic rationale of acquiring the Resin Designs assets in September 2016? Why did Resin Designs sell the businesses to you? Resin Designs’ owners felt that the combination of their product design and Chase’s global reach was the right long-term strategy to continue to develop their business. We felt this was an excellent add-on to our business in terms of size, future potential, overlap in our distribution channels, and fit within our overall strategy. What were the EBITDA margins of the acquired Resin Designs business? We do not directly disclose product line margins, but we have provided pro forma financial information in our filings during fiscal 2017. We expect this investment to continue to grow and meet our expectations, and deliver results accretive to the Company. What was the rationale for the sale of the Fiber Optics Cable Components (FOC) business to Roblon in April 2017? The Company’s initial 50% share in the FOC business was part of our acquisition of NEPTCO in fiscal 2012 (NEPTCO JV). In fiscal 2015, we acquired the other 50% equity share owned by Owens Corning, to give us full control in managing the business. Because of its low growth and margin prospects, and a customer, supplier and equipment base separate from our other businesses, Fiber Optic Cable Components was determined to not be part of Chase’s long-term strategy. The business was worth more as an add-on to Roblon, an established player, than to Chase. Moreover, the deal allows Chase to offset certain fixed costs in our Granite Falls, NC location by providing services and leasing space, while we plan our future uses of the facility and its workforce.

How does the acquisition of Zappa Stewart in December 2017 fit into Chase’s strategy? We see this as a continuation of our desire to invest in specialty chemical opportunities where products provide attributes of protection at a low cost and high value. While the business derives some revenue from Wire & Cable customers, the attraction was for products in diversified areas such as medical, consumer, environmental and construction applications. What synergies do you expect once you combine Zappa Stewart with Chase’s ongoing operations? We have not justified this investment on integration of this business into Chase, but we anticipate some logical cost savings by bringing this business onto Chase’s ERP system, support systems and shared services platform. Can you clarify what you mean by accretive to earnings? We see Zappa Stewart as increasing our earnings per share after taking into account one-time transaction costs and financing costs. Was the Zappa Stewart transaction part of an auction? This deal did not involve an auction, as principals on both sides who have had decades-long relationships saw the benefits of combining strengths of each company together to maximize value. Frequently Asked Questions (13)

Why did the former owners of Zappa Stewart sell this business ? There was a desire by one of the owners to scale back a portfolio of businesses as part of a retirement plan, and a desire by other owners to continue to build the business. Combining SSA and Zappa-Tec into one entity enabled an orderly exit for some and the opportunity for other members to continue to grow the business under the Chase umbrella. Can you explain how tax reform and the Tax Cuts and Jobs Act will impact the Zappa Stewart deal? Was that the reason for the December 31, 2017 close date? We justified this business under then-existing tax laws. We see the tax reform changes as being beneficial to certain aspects of this deal as well as Chase as a whole. Opportunity exists to accelerate depreciation on equipment purchased as part of the transaction. The timing of the close had nothing to do with tax considerations. We elected to observe the combination of SSA and Zappa-Tec for one full quarter to evaluate performance of the combined business. What was the multiple that was paid on the acquisition of Zappa Stewart? We are not disclosing this information now. Value on the business was not based upon a multiple of revenue, but rather on profit and cash flow dynamics. Further details may be shared at a later time. The investment was well within overall Chase metrics for gross margin, EBITDA margin, and other financial metrics. [END OF INVESTOR PRESENTATION] Frequently Asked Questions (14)
