“Our customers expect a lot from us and are continually raising the bar. And we continually challenge ourselves to exceed their expectations with superior solutions.”

Forward-Looking Statements Certain statements in this presentation are forward-looking. These may be identified by the use of forward-looking words or phrases such as “believe”; “expect”; “anticipate”; “should”; “planned”; “estimated”; “forecasted”; and “potential”, among others. These forward-looking statements are based on Chase Corporation’s current expectations. The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for such forward-looking statements. To comply with the terms of the safe harbor, the Company cautions investors that any forward-looking statements made by the Company are not guarantees of future performance and that a variety of factors could cause the Company's actual results and experience to differ materially from the anticipated results or other expectations expressed in the Company's forward-looking statements. The risks and uncertainties which may affect the operations, performance, development and results of the Company's business include, but are not limited to, the following: uncertainties relating to economic conditions; uncertainties relating to customer plans and commitments; the pricing and availability of equipment, materials and inventories; technological developments; performance issues with suppliers and subcontractors; economic growth; delays in testing of new products; the Company’s ability to successfully integrate acquired operations; the effectiveness of cost-reduction plans; rapid technology changes and the highly competitive environment in which the Company operates. Important factors that could cause actual results to differ materially from our expectations are disclosed under Item 1A (“Risk Factors”) in our latest Annual Report on Form 10-K filed with the Securities and Exchange Commission, and should be read together with this presentation. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statement was made. Further Information This presentation should be read together with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and the related notes thereto included in our public filings. Non-GAAP Financial Measures This presentation includes certain non‐GAAP financial measures intended to supplement, not substitute for, comparable GAAP financial measures. Reconciliations of non‐GAAP financial measures to GAAP financial measures are provided within this presentation. Investors are urged to consider carefully the comparable GAAP measures and the reconciliations to those measures provided. EBITDA, EBITDA Margin, Adjusted EBITDA, Segment EBITDA, Segment EBITDA Margin and Free Cash Flow are non-GAAP financial measures. The Company believes that EBITDA, EBITDA Margin, Adjusted EBITDA, Segment EBITDA, Segment EBITDA Margin and Free Cash Flow are useful performance measures which are used by its executive management team to measure operating performance, to allocate resources, to evaluate the effectiveness of its business strategies and to communicate with its board of directors and investors concerning its financial performance. The Company believes EBITDA, EBITDA Margin, Adjusted EBITDA, Segment EBITDA, Segment EBITDA Margin and Free Cash Flow are commonly used by financial analysts and others in the industries in which the Company operates, and thus provide useful information to investors. Our measurement of EBITDA, EBITDA Margin, Adjusted EBITDA, Segment EBITDA, Segment EBITDA Margin and Free Cash Flow may not be comparable to similarly-titled measures used by other companies. Non-GAAP financial measures should be considered in addition to, and not as an alternative to, the Company’s reported results prepared in accordance with GAAP. See the Financial Appendix for a reconciliation of these non-GAAP measures to the most comparable GAAP financial measures. Safe Harbor Statement

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, mining/drilling, etc.). Our fiscal 2015 acquisition of our specialty chemical intermediates product line and our fiscal 2017 acquisition of Resin Designs 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 2014, 2015 and 2016, 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. Construction Materials segment comprises principally project-oriented product offerings that are primarily sold and used as “Chase”-branded products. 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. 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 $4,290, $2,642 and $2,046 for fiscal 2014, 2015 and 2016, respectively, these do not include: Resin Designs, LLC 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. Energy end-market exposure has been a headwind to your business. Can you disclose what % of your business is tied to this end-market? It has been a headwind impacting our top line. We believe that the bottom line effect on us has been somewhat mitigated by reductions in commodities costs experienced by our suppliers’ industries. We are also involved in ongoing cost-reduction initiatives. We do not disclose data at that level of detail. What is your overall exposure to the paper end-market? Laminated Durable Paper Products is one of the offerings of our Specialty Products product line. We do not disclose results at the individual product line level, but only significant period-over-period changes when applicable.

Frequently Asked Questions (6) 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. Your top line has been relatively flat but increased this past quarter (second quarter of fiscal 2017). Can you elaborate? Through specific market and product development investment, we are seeing gains in certain businesses: electronic and industrial coatings, pulling and detection and coating and lining systems. The addition of Resin Designs also aided the increase in top line by an additional $4.0 million in the quarter (with $6.6 million in total sales since our purchase of the business on September 30, 2016). 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 (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 Mergers, Acquisitions and Divestitures 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. What are your thoughts on the impact federal tax reform might have on your tax rate? We are cautiously optimistic that with the legislative makeup and executive branch being aligned on corporate tax rates something could develop. We normally recognize income tax expense close to the statutory rate, so any reduction in the headline rate would likely be to our benefit. Additionally, we have historically utilized the domestic manufacturing tax deduction (Section 199) to lower our tax expense, and would hope this will continue to be an option following any possible changes. The details of how any changes are implemented, including any possible changes in state and foreign taxes, will be important, but are also presently unpredictable.

Frequently Asked Questions (9) You recently 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. What is the maximum level of leverage that you are comfortable having on your balance sheet? Our new 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 as such 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) 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 services and inclusion in our 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 (11) Can you walk through the strategic rationale of acquiring the Resin Designs assets? 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? 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.
